Good afternoon,

There are 1250 citations in today’s scan. 657 were considered primary research or review literature.

Highlights today include:

 

CANADA

·       Yau et al investigate an outbreak in an Urban hemodialysis Unit. They describe the course of a COVID-19 outbreak in the unit and the infection control measures taken for mitigation. By implementing universal screening by RT-PCR and universal droplet and contact precautions they were able to prevent further transmissions in the unit.

·       Mohammed et al., examine how mask usage by Canadians changed in the months since the onset of the pandemic in Canada. Despite the policy reversal on masks by Canadian public health officials, the survey data collected from the COVID-19 Monitor indicate that Canadians were responsive to changing guidance, self-reported usage rises from 5 percent in late March to 63 percent by early June.  Notably, the inflection point appears to take place in early April and corresponds with the issuance of revised guidance on masks by PHAC.

·       Pacheco et al., highlight that marginalized workers in Canada (e.g., women, migrants, people facing financial hardships) reported lower job security, and having temporarily lost one’s job was negatively associated with job security during the pandemic.

IPAC

·       Heilingloh et al., determined the susceptibility of SARS-CoV-2 to irradiation with ultraviolet light. The UVC dose required for complete inactivation was 1,048 mJ/cm2. UVA exposure demonstrated only a weak effect on virus inactivation over 15 minutes. Hence, inactivation of SARS-CoV-2 by UVC irradiation constitutes a reliable method for disinfection purposes in health care facilities and for preparing SARS-CoV-2 material for research purpose. 

TRANSMISSION

·       Kim et al. suggest that remote airborne transmission of SARS-CoV-2 from hospitalized COVID-19 patients is uncommon when aerosol-generating procedures have not been performed.

EPIDEMIOLOGY

·       Jeong et al suggest that true asymptomatic SARS-CoV-2 infection may be rare.  In their case series of 40 hospitalized laboratory confirmed SARS-CoV-2 cases prevalence of asymptomatic infection was 5%, lower than previously reported, and that of presymptomatic infection was 13%.  They suggest that cough, fever, myalgia, rhinorrhea or nasal congestion, and diarrhea are adequate screening criteria for covering all symptoms of SARS-CoV-2 infection.

·       Akinbani et al: estimated seroprevalence of SARS-CoV-2 among healthcare, first response, and public safety personnel by conducting antibody testing. , Of 16,403 participants, 6.9% had SARS-CoV-2 antibodies. In adjusted analyses, seropositivity was associated with exposure to SARS-CoV-2–positive household members and working within 15 km of Detroit. Nurse assistants and nurses had higher likelihood of seropositivity than physicians. Working in a hospital emergency department increased the likelihood of seropositivity. Consistently using N95 respirators and surgical facemasks decreased the likelihood of seropositivity.

·       Anand et al: described the clinic-demographic profile and viral load in neonates born to COVID 19 positive mothers. Viral load in neonates was comparable with the Ct reported from adults; however, neonates had milder clinical manifestations. All 7 neonates who tested positive for COVID 19 were subsequently discharged. Six of the 7 neonates were asymptomatic and 1 neonate needed respiratory support (indication being prematurity) which resolved after 48 h. Viral loads of mothers with COVID 19 positive neonates compared with mothers with COVID 19 negative neonates for E and RdRp gene were also statistically non-significant. The majority (93%) of neonates tested later than 48 h (roomed in with mother and breastfed) tested negative.

·       Fond et al., suggests that schizophrenia (SCZ) patients are not overrepresented among COVID-19 hospitalized patients, but SCZ is associated with excess COVID-19 mortality (adjusted odds ratio 4.36 95% CI: 1.09–17.44]; P = 0.038, adjusted for  age, sex, smoking status, obesity and comorbidity), confirming the existence of health disparities described in other somatic diseases.

·       Ehrhardt et al investigated data from SARS-CoV-2 infected 0-19 year olds, who attended schools/childcare facilities, to assess their role in SARS-CoV-2 transmission after these establishments reopened in Germany. Six of the 137 cases were found to have infected a total of 11 additional pupils. The remaining cases with information on school attendance were caused by sources outside of school and childcare facilities. Their findings suggest that child-to-child transmission in schools and childcare facilities is uncommon and not the primary cause of SARS-CoV-2 infection in children. Based on their estimation there could be one secondary case per roughly 25 infectious school days.

·       Pierce et al. compared cytokine, humoral, and cellular immune responses in pediatric (n=65) and adult (n=60) patients with COVID-19 at a metropolitan hospital system in New York City. The pediatric patients had a shorter length of stay, decreased mechanical ventilation requirements, and lower mortality compared to adults. The serum concentrations of IL-17A and IFN-γ, but not TNF-α or IL-6, were inversely related to age. Adults mounted a more robust T cell response to the viral spike protein than pediatric patients. Moreover, serum neutralizing antibody titers and antibody-dependent cellular phagocytosis was higher in adults compared to pediatric COVID-19 patients. The neutralizing antibody titer correlated positively with age and negatively with IL-17A and IFN-γ serum concentrations.

·       Liu, et al. enrolled 140 medical workers with COVID‐19 in Wuhan. Epidemiological, demographic, clinical, laboratory, radiological, treatment and clinical outcome data were collected, and predictors of the duration of viral shedding were explored through multivariable linear regression analysis. Glucocorticoid treatment and lymphocytes less than 1.1 × 109/L are associated with prolonged viral shedding. Early admission and rIFN‐α treatment help shorten the duration of viral shedding.

·       Massey, et al. determined the prevalence and type of a wide variety of respiratory pathogens in 12,075 United States subjects tested for SARS-CoV-2 infection in March and April 2020. Infections with other respiratory pathogens were present in both SARS-CoV-2 + and SARS-CoV-2- subjects. Among the co-pathogens present in both subject groups were K. pneumoniae and M. catarrhalis. Advanced age and nursing home status were associated with higher SARS-CoV-2 + and co-infection rates.

·       Gao et al., (preprint) describe the use of human activities measured by venable distances and activity density as a good early indicator for spread of COVID-19 during the early in the pandemic.  They show significant time lag relationships between changes in activity and the reproduction number, indicating the possible utility of human activitiy measurements in predicting COVID-19 transmission in the community

CLINICAL DATA

·       Chao et al report a female infant born to a woman who had been diagnosed with COVID-19 at 26+6 weeks of pregnancy. Throat swabs obtained from the infant on day 2, 3 and 8 after birth were all negative for SARS-Cov-2. SARS-Cov-2 IgM in the neonatal serum were negative on samples from day 2 and 8. Elevated IgG levels were observed, suggesting that antibodies may have come from the mother. According to this case report, no intrauterine vertical transmission was found.

·       Corcorran et al describe a SARS-CoV-2 outbreak within an inpatient geriatric psychiatry unit at the University of Washington Medical Center. Asymptomatic infection was common in this cohort of hospitalized elderly individuals (30%) despite similar duration of SARS-CoV-2 RT-PCR positivity and cycle threshold values among symptomatic and asymptomatic patients.

·       Ludzik, et al. report new dermatologic findings have been described in association with COVID-19 that can potentially be a distinguishing feature of infection. One such feature resembles chilblains and this case report represents a presentation of this feature with a 48-year-old female with violaceous lesions with surrounding pink erythema on her toes who tested negative for COVID-19.

SURVEILLANCE

·       Ferrari et al.,  Retrospectively examine routine blood tests for AST and LDH levels from 30000 patients admitted since September 2018.  The results indicate that AST and LDH levels are highly sensitive to the presence of COVID-19 and may be a good surveillance indicator of the presence of COVID-19 circulation. They also suggest in a separate paper on the same data that use of AST and LDH along side a false-negative PCR results to indicate COVID-19 would reduce the false negative rate by 4-fold.

THERAPEUTICS

·       Hueso et al report a case series of 17 consecutive patients with profound B-cell lymphopenia and prolonged COVID-19 symptoms, negative IgG-IgM SARS-CoV-2 serology and a positive RNAemia measured by digital PCR who were treated with four units of COVID-19 convalescent plasma. They found that in these COVID-19 patients unable to mount a specific humoral response to SARS-CoV-2, convalescent plasma with anti-SARS-CoV-2 antibodies no adverse events were reported and patients showed improvement of clinical symptoms and virus-specific T cell responses.

·       Kumar et al. This study aimed to study the binding potential of various phytochemicals present in multiple natural plant extract as a secondary metabolite to non-structural protein 15 (Nsp15) protein, a drug target known to play a crucial role in virulence of coronavirus. The  study successfully demonstrated the binding of phytochemicals such as sarsasapogenin, ursonic acid, curcumin, ajmalicine, novobiocin, silymarin and aranotin, piperine, gingerol, rosmarinic acid, and alpha terpinyl acetate to Nsp15 viral protein and they might play a key role in inhibiting SARS-CoV-2 replication.

·       Kumar et al evaluated the ACE2 inhibitory effects of 10 essential oils. Geranium and lemon essential oils strongly reduced the human ACE2 levels in HT-29 cells from 17.68 ng/mL to 1.43 ng/mL and 4.34 ng/mL, respectively.

·       Rasheed et al. studied 49 early-stage critically-ill COVID-19 patients in Respiratory Care Units (RCU) of three hospitals in Baghdad, Iraq. 21 received convalescent plasma while 28 (control group) did not receive it.  Patients who received convalescent plasma showed reduced infection duration and showed less death rate. Also, all the patients who were given convalescent plasma showed high levels of SARS-CoV-2 IgG and IgM three days after plasma transfusion. Plasma from donors with high SARS-CoV-2 IgG levels and donors with positive SRAS-CoV-2 IgM showed better therapeutic results than other donors.

·       Youssef et al. A synthetic form of Vasoactive Intestinal Peptide (VIP)  is currently in phase 2/3 placebo-controlled trials and has Fast Track Designation for treating Critical COVID-19  cases. Of the 21 consecutive patients with Acute Respiratory Failure in Critical COVID-19 that were administered intravenous VIP, 19 showed improvement in lungs (17 in both and 2 in one lung). A mean increase of 292% was seen for PaO2:FiO2 ratio with complete remission from respiratory failure in 9 patients and ongoing improvement in 10. In vitro anti-viral effect was seen using radiographic findings, oxygen consumption and other inflammatory markers.

CORONAVIROLOGY

·       Mege, et al. construct the phylogeny of the SARS corona virus that causes Covid-19 in various countries in the world by using the SARS Covid-19 gene database from the NCBI GenBank. The results showed that the phylogeny trees formed were obtained by 2 main monophyletic groups. The presence of sequences from China in the 2 main monophyletic groups confirms that this virus originated in the Chinese epicenter.

·       Ma, et al. created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung, heart and artery, the top tissues targeted by SARS-CoV-2. Our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2, suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly.

DIAGNOSTICS

·       Therchilsen et al compared the sensitivity of self-collected versus healthcare worker (HCW)-collected swabs for SARS-CoV-2 testing. A total of 109 participants were included, and 19 participants had SARS-CoV-2-positive results. The diagnostic sensitivity of the self-collected and HCW-collected swabs was 84.2% and 89.5%, respectively.

·       Vaz et al validated the use of saliva as a biological sample for diagnosis of COVID-19. Participants presenting with signs/symptoms suggesting SARS-CoV-2 infection underwent a nasopharyngeal swab and/or oropharyngeal swab, and saliva collection. The sensitivity and specificity of RT-PCR using saliva samples were 94.4% (95% CI 86.4–97.8) and 97.62% (95% CI 91.7–99.3), respectively. There was an overall high agreement (96.1%) between the two tests.

·       Dust et al reported that choice of test did not compromise SARS-CoV-2 detection. Commercial assays and lab developed tests for detection of SARS-CoV-2 exhibited 100% positive and negative agreement and there was no cross-reactivity with common respiratory viruses, including endemic coronaviruses.

ZOONOSES

·       Musso et al. detail the case of a domestic cat with clear clinical signs of pneumonia, confirmed by Rx imaging, that was found to be infected by SARS-CoV-2 using quantitative RT–qPCR from a nasal swab. 

PUBLIC HEALTH RESPONSE

·       Neto et al. describe Covid-19 mobile applications available for download on smartphones. The cross-sectional analysis finds 86.6% of applications were developed in 2020, 98.1% were free, 94.2% did not have accessibility for people with disabilities, and 32.7% were in English. The majority  of applications were on “case monitoring” and “symptoms, prevention, and care”. Associations between the target audience and “symptoms, prevention, and care”, as well as patient monitoring and professional training were noted.

HEALTH CARE RESPONSE

·       Okonkwo et al. present outcome data following pediatric elective surgeries in a region with high COVID-19 prevalence. Study finds the combined use of household self‐isolation, testing and screening questionnaires to have allowed for the re‐initiation of elective paediatric surgery at high volume whilst maintaining pre‐COVID‐19 outcomes in children/young people undergoing surgery.

PMC7403866; Angioedema and urticaria in a COVID-19 patient: A case report and review of the literature

Abasaeed Elhag,  SA,  Ibrahim, et al

JAAD Case Rep

Clinical data| Données cliniques

This article presents a case of angioedema and urticaria occurring in a 40-year-old previously healthy man presented to the emergency department with a 1-day history of lip and bilateral eyelid swelling and a generalized pruritic rash. Before the symptoms occurred, he had a 5-day history of mild, nonproductive cough and dyspnea with low-grade fever. Nasopharyngeal swab result for COVID-19 reverse transcriptase–polymerase chain reaction test was positive. Chest radiograph showed bilateral lower-zone opacities and infiltrations typical for COVID pneumonia of moderate severity. This article reviewed literature that described cutaneous manifestations in COVID-19. Although urticarial lesions have been described in patients with COVID-19 pneumonia, associated angioedema was rarely reported. Concluded that urticaria and angioedema are often triggered by various viral or bacterial infections, and COVID-19 infection is not an exception, adding a new member to the array of cutaneous manifestations of this enigmatic infection.

32919429; A histopathological observation regarding the possibility of hemophagocytic lymphohistiocytosis in COVID-19 patients

Abdollahi,  A,  Beigmohammadi, et al

Journal of gastrointestinal and liver diseases : JGLD

Clinical data| Données cliniques

This editorials reports on COVID-19’s  pathogenesis and suggest that critical cases of COVID-19 with poorer prognoses are characterized by evidence that points to hemophagocytic lymphohistiocytosis (HLH).  This study was conducted to examine the histopathological findings in patients who had passed away due to COVID-19. While  conducting  a  pathological  study  on  11  randomly  selected  deceased  patients  who  were  confirmed  cases  of  COVID-19,  and  following  a  post-mortem  core  needle  liver  biopsy  procedure,  the authors  found  the  presence  of  Kupffer  cell  hyperplasia and hemophagocytosis in the liver of two patients. HLH  can  be  proposed  as  the  cause  of  such  an  observation.

PMC7467028; Computer-aided detection of COVID-19 from X-ray images using multi-CNN and Bayesnet classifier

Abraham,  B,  Nair, et al

Biocybern Biomed Eng

Clinical data| Données cliniques Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

This paper investigates the effectiveness of multi-convolutional neural networks (CNN), a combination of several pre-trained CNNs, for the automated detection of COVID-19 from X-ray images.  The method was tested using two public datasets and achieved promising results on both the datasets. In the first dataset consisting of 453 COVID-19 images and 497 non-COVID images, the method achieved an AUC of 0.963 and an accuracy of 91.16%. In the second dataset consisting of 71 COVID-19 images and 7 non-COVID images, the method achieved an AUC of 0.911 and an accuracy of 97.44%. The experiments performed in this study proved the effectiveness of pre-trained multi-CNN over single CNN in the detection of COVID-19.

Impact of the COVID-19 Pandemic on the U.S. Electricity Demand and Supply: An Early View from Data

Agdas,  D,  Barooah, et al

IEEE Access

Public Health response| Interventions de santé publique Economics | Économie

This paper analyzed the electricity data until the end of May 2020, examining both electricity demand and variables that can indicate stress on the power grid. Limited this study to three states in the U.S. California, Florida and New York. The results indicate that the effect of the pandemic on electricity demand is not a simple reduction, and there are noticeable differences among regions analyzed. The variables that can indicate stress on the grid (e.g., daily peak and trough of the hourly demand, demand ramp rate, demand forecast error, and net electricity interchange) also conveyed mixed messages: some indicate an increase in stress, some indicate a decrease, and some do not indicate any clear difference. Also provided a weather-correction method, applied to a small city-wide area in North Central Florida, and discussed the implications of the estimated changes in demand. The results indicate that a 10% (95% CI [2%, 18%]) increase in electricity demand is likely to have occurred due to COVID-19 for the city analyzed.

Covid-19: statutory means of scrutinizing workers' deaths and disease

Agius,  RM

Occup Med (Lond)

Public Health response| Interventions de santé publique

This study assesses the adequacy of these statutory ( By law, covid-19 disease and deaths in workers may lead to coroners' inquests and/or Health and Safety Executive (HSE) investigations) means to yield recommendations for prevention of acquiring covid-19 infection from work. The coroners' guidance allowed a wider range of reports of death than did the HSE and conformed better with ONS data on covid-19 mortality by occupation. In the practitioner survey, 62 respondents considered a higher likelihood that reported covid-19 cases would have arisen from the scenario deemed unreportable as a 'dangerous occurrence' by HSE than the reportable scenario (P < 0.001). On average there was only one coroner's report to prevent future death from occupational disease every year in England and Wales. The HSE dealt with a yearly average of 1611 reports of work-related disease including 104 on biological agents, but has received about 9000 covid-19 reports.

A poisson autoregressive model to understand covid-19 contagion dynamics

Agosto,  A,  Giudici, et al

Risks

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We present a statistical model which can be employed to understand the contagion dynamics of the COVID-19, which can heavily impact health, economics and finance. The model is a Poisson autoregression of the daily new observed cases, and can reveal whether contagion has a trend, and where is each country on that trend. Model results are exemplified from some observed series. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Ajide,  KB,  Ibrahim, et al

Transportation Research Interdisciplinary Perspectives

Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

The study examines the extent to which lockdown measures impact on COVID-19 confirmed cases in Nigeria. Six indicators of lockdown entailing retail and recreation, grocery and pharmacy, parks, transit stations, workplaces, and residential, are considered. The study established the key following findings: First, retail and recreation, grocery and pharmacy, parks, transit stations, and workplaces are statistically significant and negatively signed as relevant predictors of the virus. Second, the impact of residential is positive and statistically significant at the conventional level.

Immuno-Informatics Quest against COVID-19/SARS-COV-2: Determining Putative T-Cell Epitopes for Vaccine Prediction

Akhtar,  N,  Joshi, et al

Infect Disord Drug Targets

Coronavirology| Coronavirologie Vaccine Research| Recherche sur les vaccins

This study attempted to design epitope based vaccine for combatting COVID-19 disease by analyzing the complete proteome of the virus by using immuno-informatics tools.  The study has predicted 5 peptide molecules that can act as potential candidate for epitope based vaccine development. Among the 5 selected epitopes, the peptide LRARSVSPK can be the most potent epitope because of its high geometric shape complementarity score, low ACE and very high response to it by the world population (81.81% global population coverage). Further, molecular dynamic simulation analysis indicated the formation of stable epitope-MHCII complex. The epitope LRARSVSPK was also found to be highly conserved among the SARS-CoV-2 isolated from different countries.

SARS-CoV-2 Seroprevalence among Healthcare, First Response, and Public Safety Personnel, Detroit Metropolitan Area, Michigan, USA, May-June 2020

Akinbami,  LJ,  Vuong, et al

Emerg Infect Dis

Epidemiology| Épidémiologie Immunology | Immunologie

This study estimated seroprevalence of severe acute respiratory syndrome 2 (SARS-CoV-2) among healthcare, first response, and public safety personnel in Michigan. Of 16,403 participants, 6.9% had SARS-CoV-2 antibodies. In adjusted analyses, seropositivity was associated with exposure to SARS-CoV-2-positive household members ( aOR] 6.18, 95% CI 4.81-7.93) and working within 15 km of Detroit (aOR 5.60, 95% CI 3.98-7.89). Nurse assistants (aOR 1.88, 95% CI 1.24-2.83) and nurses (aOR 1.52, 95% CI 1.18-1.95) had higher likelihood of seropositivity than physicians. Working in a hospital emergency department increased the likelihood of seropositivity (aOR 1.16, 95% CI 1.002-1.35). Consistently using N95 respirators (aOR 0.83, 95% CI 0.72-0.95) and surgical facemasks (aOR 0.86, 95% CI 0.75-0.98) decreased the likelihood of seropositivity.

Depressive, drug abusive, or informative: Knowledge-aware study of news exposure during COVID-19 outbreak

Alambo,  A,  Gaur, et al

 

Public Health response| Interventions de santé publique

This position paper proposed a novel framework for assessing the spatio-temporal-thematic progression of depression, drug abuse, and informativeness of the underlying news content across the different states in the United States. The framework employed an attention-based transfer learning technique to apply knowledge learned on a social media domain to a target domain of media exposure. Used neural semantic parsing, and background knowledge bases in a sequence of steps called semantic filtering. Achieved promising preliminary results on three variations of Bidirectional Encoder Representations from Transformers (BERT) model. Compared the findings against a report from Mental Health America and the results showed that this fine-tuned BERT models performed better than vanilla BERT.

AlAteeq,  DA,  Aljhani, et al

Journal of Infection and Public Health

Healthcare Response | Réponse des soins de santé

This  cross-sectional study sought to explore depression and anxiety levels among healthcare providers during the COVID-19 outbreak in Saudi Arabia. The respondents represented various healthcare occupations: administrators (28.49%), nurses (26.29%), physicians (22.11%), non-physician specialists (13.94%), technicians (6.77%), and pharmacists (2.30%). The majority of them were male (68.1%). More than half of them had depressive disorder (55.2%), which ranged from mild (24.9%), moderate (14.5%), and moderately severe (10%) to severe (5.8%). Half of the sample had generalized anxiety disorder (51.4%), which ranged from mild (25.1%) and moderate (11%) to severe (15.3%). Multivariate analysis showed that males were significantly less predicted to have anxiety (Beta = −0.22, P-value <0.04), 30–39 years age group were significantly more predicted to have depression and anxiety group (Beta = 0.204, P-value <0.001 and beta = 0.521, P-value <0.003 respectively), and nurses had significantly higher mean score of anxiety (Beta = 0.445, P-value <0.026).

Covid-19 related stigma, examining the view of the general public of stigma toward people with covid-19 in Iraq

Alatrany,  SSJ

International Journal of Psychosocial Rehabilitation

Public Health response| Interventions de santé publique

The current study aimed to examine the view of the general public of stigma toward people with COVID-19 in Iraq. The findings showed that the participants generally agreed people could be subjected to stigma if they have COVID-19. There was no significant difference between males and females. In addition, people who have confirmed COVID-19 patients in their family or of friend reported high possibility of stigma.

Epidemiology| Épidémiologie Clinical data| Données cliniques

This study observed the clinical course of symptomatic pregnant women diagnosed with or suspected of having COVID-19. The mean duration of hospitalization was 6.1 ± 3 days. The gestational age of the patients ranged from 6w2d to 40w2d. Thirty-five patients' CT scan findings suggested viral pneumonia. Four patients delivered vaginally, and 10 patients underwent a cesarean section during the study period. Four of the cesarean deliveries were indicated due to COVID-19 hypoxemia-related fetal distress. Four patients were admitted to the intensive care unit (ICU) after the cesarean section.

Estimates of dynamics of the COVID-19 pandemic and of its impact on the economy

Albu,  LL,  Preda, et al

Romanian Journal of Economic Forecasting

Economics | Économie

This study assessed the impact of COVID19 pandemic impact on the economic growth. The study proposed an estimation-simulation model to analyse the dynamics of the spread of epidemic among the population, and built a model with differential equations for a special logistic time-function, which resulted in certain key-values and four phases of its evolution. Moreover, by simulating the daily dynamics of pandemic at three levels (world, EU, and Romania) we estimated the impact of pandemic on the economic growth until the end of this year.

Moral Disengagement and Generalized Social Trust as Mediators and Moderators of Rule-Respecting Behaviors During the COVID-19 Outbreak

Alessandri,  G,  Filosa, et al

Frontiers in Psychology

Public Health response| Interventions de santé publique

This study tested a theoretical model with moral disengagement, a mediator, and generalized social trust (GST), a mediator and a moderator of the relationship between personality traits and rule-respecting behaviors (i.e., social distancing and stay-at-home), during the coronavirus disease 2019 (COVID-19) outbreak in Italy. The data were collected on 1520 participants (61% males). General results are threefold: (1) moral disengagement mediated the relationship between emotional stability, narcissism, psychopathy, and social distancing; (2) among components of GST, trust in Government mediated the relationship between psychopathy and social distancing; trust in known others mediated the relationship between emotional stability, agreeableness, and Machiavellianism with total number of exits; trust in unknown others mediated the relationship of emotional stability, agreeableness, conscientiousness, and psychopathy with average daily number of exits; (3) GST moderated the indirect effect of personality traits on rule-respecting behaviors through moral disengagement.

On global dynamics of COVID-19 by using SQIR type model under non-linear saturated incidence rate

Algehyne,  EA,  Din, et al

Alexandria Engineering Journal

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

This paper investigates a new mathematical SQIR model for COVID-19 by means of four dimensions; susceptible, quarantine, infected and recovered (SQIR) via Non-linear Saturated Incidence Rate. First of all the model is formulated in the form of differential equations. Disease-free, endemic equilibriums and Basic Reproduction Number are found for the said model. Local Stability is analyzed through Jacobean Matrix while Lyapunov Function is constructed for the study of Global Stability of the Model. Using nonstandard finite difference method, numerical results are simulated. By Simulation, we mean how protection, exposure, death and cure rates affect the Susceptible, Quarantined, Infected and recovered population with the passage of time. © 2020 Faculty of Engineering, Alexandria University

Energy demand in the state of Kuwait during the Covid-19 pandemic: Technical, economic, and environmental perspectives

Alhajeri,  HM,  Almutairi, et al

Energies

Public Health response| Interventions de santé publique Economics | Économie

The present paper reports the impact of the Covid-19 pandemic on the electricity peak load and power generation in the State of Kuwait during the partial and full curfews imposed in March, April and May 2020. Comparison of measured peak demand for 2019 and 2020 with predicted peak demand for 2020 has: (i) enabled an accurate evaluation of residential energy consumption in the state of Kuwait at nearly 18 MWh yearly the highest energy consumption per capita in the world, (ii) shown that the imposition of the curfews to reduce the spread of COVID-19 caused a fall in the demand for electrical power of 17.6% compared with the expected demand and (iii) quantified the reduction in CO2, NOx and CO pollutant emissions produced by power plants due to less fuel being consumed.

Impact of COVID-19 pandemic on agricultural wholesale prices in India: A comparative analysis across the phases of the lockdown

Ali,  J,  Khan, et al

Journal of Public Affairs

Public Health response| Interventions de santé publique Economics | Économie

This paper attempts to analyse the impact of COVID-19 lockdown on wholesale prices of the agricultural commodities particularly fruits and vegetables in the Union Territory of Jammu and Kashmir, India. The analysis of the difference in the weighted average wholesale prices across markets and commodities has shown a mixed response. The most hydrating perishable fresh fruits and vegetables with high water content have faced a significant decline in wholesale prices during the lockdown. On the contrary, other perishable fruits and vegetables have realized a gain in the average wholesale prices. The weighted average wholesale price has also declined over the phases of the lockdown.

Clinical data| Données cliniques

COVID-19 is associated with severe coagulopathy. We present three cases of colonic ischemia that can be attributed to the hypercoagulable state related with SARS-CoV2 and disseminated intravascular coagulation. Three males aged 76, 68 and 56 with respiratory distress presented episodes of rectal bleeding, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia. One patient (case 2) in which a computed tomography (CT) scan showed perforation of the gangrenous cecum underwent surgery. D-dimer levels were markedly increased (2,170, 2,100 and 7,360 ng/ml) in all three patients. All three patients died shortly after diagnosis.

Data on multisystem inflammatory syndrome in children (MIS-C) related to coronavirus disease-19 (COVID-19) is increasing in the current COVID-19 pandemic. We present a 16 year old male who was hospitalized in July 2020 under adult medical service due to Kawasaki-like disease symptoms. Diagnosis of MIS-C related to COVID-19 was established by clinical features, elevated inflammatory markers, and positive SARS−COV 2 immunoglobulin G. We encourage all clinicians especially who practice adult medicine to be familiar with signs and symptoms of MIS-C to avoid delayed diagnosis and complications. © 2020 The Author(s)

Healthcare Response | Réponse des soins de santé

This study estimated the impact of the coronavirus disease 2019 (COVID-19) pandemic on the organization of Spanish hospital emergency departments (EDs).  A total of 246 (87%) responses were received. The majority of the EDs organized a triage system, first aid, and observation wards; areas specifically for patients suspected of having COVID-19 were newly set apart. The nursing staff was increased in 83% of the EDs (with no subgroup differences), and 59% increased the number of physicians (especially in large hospitals and locations where the COVID-19 incidence was high). Diagnostic tests for the severe acute respiratory syndrome coronavirus 2 were the resource the EDs missed most: 55% reported that tests were scarce often or very often. Other resources reported to be scarce were FPP2 and FPP3 masks (38% of the EDs), waterproof protective gowns (34%), and space (32%). More than 5% of the physicians, nurses, or other emergency staff were on sick leave 20%, 19%, and 16% of the time. These deficiencies were greatest during the last half of March, except for tests, which were most scarce in the first 15 days.

In the present study, more than 51 phytochemicals of J. procera were docked against the main protease of COVID-19. Rutin gave the highest interaction score among all the phytochemicals and the commercially available antiviral drugs. Lopinavir showed the second highest binding score. Rutin and lopinavir were further investigated using homology models of COVID-19. Rutin showed a better inhibition score in 9 of the 11 of homology models compared with lopinavir. Analysis of ligand-protein interaction contacts revealed that 3 residues (Glu166, Gly143, and Thr45) of the main protease formed hydrogen bonds with rutin.

This study investigated whether anti-influenza vaccination plays a role in minimizing the diffusion of COVID-19 in the Italian population aged 65 and over.  At univariate analyses, the influenza vaccination coverage rates correlated negatively with all COVID-19 outcomes (Beta ranging from −134 to −0.61; all p < 0.01). At multivariable analyses, influenza vaccination coverage rates correlated independently with SARS-CoV-2 seroprevalence (Beta (95% C.I.): −130 (−198, −62); p = 0.001), hospitalizations for COVID-19 symptoms (Beta (95% C.I.): −4.16 (−6.27, −2.05); p = 0.001), admission to intensive care units for reasons related to SARS-CoV-2 (Beta (95% C.I.): −0.58 (−1.05, −0.12); p = 0.017), and number of deaths attributable to COVID-19 (Beta (95% C.I.): −3.29 (−5.66, −0.93); p = 0.010). The R2 observed in the unadjusted analysis increased from 82% to 159% for all the considered outcomes after multivariable analyses.

Clinical profile, viral load, management and outcome of neonates born to COVID 19 positive mothers: a tertiary care centre experience from India

Anand,  P,  Yadav, et al

European journal of pediatrics

Epidemiology| Épidémiologie Clinical data| Données cliniques

This study  described the clinicodemographic profile and viral load in neonates born to COVID 19 positive mothers. Of 2947 deliveries, 69 mothers were COVID 19 positive (2.3%), with 1 abortion, 2 macerated stillbirths and 2 fresh stillbirths as pregnancy outcomes. Of 65 tested neonates, 10.7% (7) were confirmed COVID 19 positive by RTPCR (reverse transcriptase-polymerase chain reaction). Viral load (cycle threshold, Ct of E, RDRp) in neonates was comparable with the Ct reported from adults; however, neonates had milder clinical manifestations. All 7 neonates who tested positive for COVID 19 were subsequently discharged. Six of the 7 neonates were asymptomatic and 1 neonate needed respiratory support (indication being prematurity) which resolved after 48 h. Maternal and neonatal comparison of Ct of E and RdRp gene was statistically non-significant (25.97 vs 19.68, p = 0.34 and 26.5 vs 25.0, p = 0.84). Viral loads of mothers with COVID 19 positive neonates compared with mothers with COVID 19 negative neonates for E and RdRp gene were also statistically non-significant (25 vs 27.19, p = 0.63 and 19.6 vs 27.6, p = 0.08). The majority (93%) of neonates tested later than 48 h (roomed in with mother and breastfed) tested negative.

We develop a multivariate time series model of employment in 19 sectors for Australia. We use this model to determine the long-run effect of a 1% increase in economic activity in any chosen sector on aggregate employment. Our findings point to manufacturing and construction sectors as those that generate the largest positive spillovers for the aggregate economy. Moreover, we provide an interactive web-based app that produces our model's forecasts based on any user-specified scenario. As the restrictions associated with the COVID-19 pandemic evolve, the sectoral employment multipliers together with these interactive tools will provide useful information for policymakers. © 2020 The University of Melbourne, Melbourne Institute: Applied Economic & Social Research, Faculty of Business and Economics

COVID-19, nausea and vomiting

Andrews,  PLR,  Cai, et al

J Gastroenterol Hepatol

Clinical data| Données cliniques

This study examined the incidence of nausea (N) and vomiting (V) during infection before defining potential mechanisms. Estimated that the overall incidence of nausea (median 10.5%), although variable, is comparable to diarrhoea.  Proposed that emetic mechanisms are activated by mediators released from the intestinal epithelium by SARS-CoV-2 modulate vagal afferents projecting to the brainstem and after entry into the blood, activate the area postrema (AP). The receptor for spike protein of SARS-CoV-2, angiotensin 2 converting enzyme (ACE2), and transmembrane protease serine (for viral entry) are expressed in upper GI enterocytes, ACE2 is expressed on enteroendocrine cells (EECs), and SARS-CoV-2 infects enterocytes but not EECs (studies needed with native EECs). The resultant virus-induced release of epithelial mediators due to exocytosis, inflammation and apoptosis provides the peripheral and central emetic drives. Additionally, data from SARS-CoV-2 shows an increase in plasma angiotensin II (consequent on SARS-CoV-2/ACE2 interaction), a centrally (AP) acting emetic, providing a further potential mechanism in COVID-19.

Clinical data| Données cliniques

The current study attempts to investigate the relationships between infection, mortality and recovery rates from coronavirus and the prevalence of ADHD at the US statewide level.  Based on information from 2011 regarding the prevalence of ADHD across the US by state, findings suggest that, while there are no correlations between ADHD and population size, infection and mortality rates from coronavirus, recovery rates (recovery-population ratio) rise with the prevalence of ADHD. Consequently, a possible explanation is that in coping with the disease, ADHD might provide an evolutionary advantage.

Transportation Research Interdisciplinary Perspectives

Public Health response| Interventions de santé publique

This study aims to interpret the change in the population density of Sapporo city in the emergency's period declaration using big data obtained from mobile spatial statistics. The results indicate that, in the time of refraining from traveling, the city's residents have been more likely to stay home and less likely to travel to the center area. This has led to a decrease of up to 90% of the population density in crowded areas. The study's outcomes partly explain the statement of reducing 70%–80% of contact between people in line with the purpose of the emergency declaration.

This study estimated the prevalence of COVID-19 in a large population of Parkinson's disease (PD) patients and compared the infection rate with the general population of the same region of Italy. Eight PD patients, meaning 0.57% of interviewed, were found to be positive to COVID-19.  75% of PD patients (n = 6/8) died because of COVID-19, while the mortality rate in the general population of Piedmont was 11.53% (n = 3186/27,622).  PD symptoms worsened in all patients, early before or early after the onset of infection signs, which consisted in fever (100% of patients), weakness (43%), muscle pain (29%), dyspnea (29%), and cough (14%). Interestingly, one patient developed disabling dyskinesia as the presenting symptom of the infection. All patients were hospitalized, and three were already institutionalized at the moment of infection. All were treated with levodopa, alone or in combination with dopamine agonists.

We performed a survey among Romanian physicians in order to see how many of them would administer prophylactically hydroxychloroquine to themselves or to people close to them, and if they would participate to a randomized controlled trial. A total of 785 answers were collected. Nine physicians (1.1%) thought that there was clear evidence on prescribing hydroxychloroquine prophylaxis, 375 (48%) considered the evidence acceptable, 348 (44.3%) considered it weak, whereas 53 (6.8%) answered there was no evidence. 59 (7.5%) respondents were determined to take it (of which 31 = 4% already took), 192 (24.5%) were inclined to take, 271 (34.5%) were not decided yet. 175 (22.3%) of respondents declared they (would) give the treatment to their close ones, and this decision was associated with a higher age (P = 0.003), and the opinion that there was evidence (P < 0.001). When asked about the source of the treatment regimen, 286 (36.4%) indicated a scientific paper, while no scientific paper about the prophylaxis with hydroxychloroquine existed at that time. 718 (91.5%) considered a randomized clinical trial necessary (RCT), but only 333 (42.4%) answered they would enrol in such a trial. There was only a very weak correlation (Kendall's tau _b = 0.255, P < 0.001) between the belief that an RCT is necessary and the willingness to enrol in such an RCT.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We propose a forecasting method for predicting epidemiological health series on a two-week horizon at the regional and interregional level. The approach is based on model order reduction of parametric compartmental models, and is designed to accommodate small amount of sanitary data. The efficiency of the method is examined in the case of the prediction of the number of hospitalized infected and removed people during the first pandemic wave of COVID-19 in France, which has taken place approximately between February and May 2020. Numerical results illustrate the promising potential of the approach.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

In this study, a Deep Neural Network approach using Monte Carlo is proposed for generating a database to train networks for estimating the optimal parameters of a SIR epidemiology model. The number of total infected people as of April 7 in Spain is considered as input to the Deep Neural Network. The adaptability of the model was evaluated using the latest data upon completion of this paper, i.e., April 14. The date range for the peak of infected people (i.e., active cases) based on the new information is estimated to be within 74 to 109 days after the first recorded case of COVID-19 in Spain. In addition, a curve fitting measure based on the squared Euclidean distance indicates that according to the current data the peak might occur before the 86th day. Collectively, Deep Neural Networks have proven accurate and useful tools in handling big epidemiological data and for peak prediction estimates.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

Article in Spanish. This study aimed to highlight the importance of the analysis of non-linear correlation models and all the statistical inference procedures for the design of a mathematical model that allows the prediction of data based on the age of positive cases of COVID-19 in Colombia. With an R2 value of 0.9969 very close to 1 and a hypothesis test that guarantees the veracity of the alternative hypothesis, the ideal mathematical model that aligns the growth data of COVID-19 is quadratic. The quadratic model is positive and increasing as long as the number of infections continue to grow; therefore, it is not an ideal moment to speak of a flattening of the curve. If the growth is constant, the model could have an exponential trend.

Weobserve that the number of deaths and cases in different re-gions would have been much smaller had the lockdowns beenimposed earlier and had the re-openings been done later, es-pecially among indoor bars and restaurants. We also analyzethe speculated impact of herd immunity on the spread giventhe population of each region and show that lockdown policieshave a very strong impact on the spread regardless of the levelof prior infections.

The C-C Chemokine Receptor Type 4 Is an Immunomodulatory Target of Hydroxychloroquine

Beck,  TC,  Beck, et al

Frontiers in Pharmacology

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

Despite an abundance of empirical data, the mechanism(s) involved in the immunomodulatory activity of hydroxychloroquine have not been characterized. Using the unbiased chemical similarity ensemble approach (SEA), we identified C-C chemokine receptor type 4 (CCR4) as an immunomodulatory target of hydroxychloroquine. The crystal structure of CCR4 was selected for molecular docking studies using the SwissDock modeling software. In silico, hydroxychloroquine interacts with Thr-189 within the CCR4 active site, presumably blocking endogenous ligand binding. However, the CCR4 antagonists compound 18a and K777 outperformed hydroxychloroquine in silico, demonstrating energetically favorable binding characteristics. Hydroxychloroquine may subject COVID-19 patients to QT-prolongation, increasing the risk of sudden cardiac death. The FDA-approved CCR4 antagonist mogalizumab is not known to increase the risk of QT prolongation and may serve as a viable alternative to hydroxychloroquine. Results from this report introduce additional FDA-approved drugs that warrant investigation for therapeutic use in the treatment of COVID-19.

Assessment of effective imidazole derivatives against SARS-CoV-2 main protease through computational approach

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

A docking study was executed on eighteen imidazole derivatives based on 7-chloro-4-aminoquinoline against novel Coronavirus (SARS-CoV-2). The result indicate that Molecules N° 3, 7 and 14 have more binding energy with SARS-CoV-2 main protease recently crystallized (pdb code 6LU7) in comparison with the other imidazole derivatives and the two drug; Chloroquine and hydroxychloroquine. Because of the best energy of interaction, these three molecules could have the most potential antiviral treatment of COVID-19 than the other studied compounds. The structures with best affinity in the binding site of the protease have more than 3 cycles and electronegative atoms in the structure. This may increase the binding affinity of these molecules because of formation of π-bonds, halogen interactions and/or Hydrogen bond interactions between compounds and the enzyme. So, compounds with more cycles and electronegative atoms could have a potent inhibition of SARS-CoV-2 main protease.

Article in German. In a cross-sectional survey we investigated the caseload and the perceived challenges in Southern Bavarian primary care practices during the first phase of the pandemic. A total of 160 questionnaires were available for analysis (response rate 76 %). 92 % of participants had seen at least one patient with a SARS-CoV-2 infection, two colleagues saw more than 100 infected patients; the median number was 10.63 % had at least one patient hospitalized and 31 % at least one death associated with SARS-CoV-2 infection. In contrast, only 23 % of the nursing homes looked after by the participants were affected by infections; in individual nursing homes, however, there were numerous hospitalizations and deaths. In 18 % of practices at least one member of the team was tested positive for SARS-CoV-2. The most important challenges were the lack of protective equipment and the adaptation of the practice process to the pandemic situation. With regard to a possible “second wave”, the need for protective equipment and a better flow of information were central issues.

Clinical data| Données cliniques Therapeutics| Thérapeutique

The aim of this study was to assess the effects of these drugs on QT interval and outcome in a COVID-19 population. A total of 112 consecutive COVID-19 patients were included in this analysis and were divided in 3 groups according to the receiving therapeutic regimens: 19 (17%) patients in Group 1 (no treatment), 40 (36%) in Group 2 (HCQ only), 53 (47%) in Group 3 (HCQ/AZT). A prolonged QTc interval was found in 61% of patients treated with HCQ alone or in combination with AZT, but only 4 (4%) patients showed a QTc > 500 ms. HCQ/AZT combination determined a greater increase of QTc duration compared to the other two strategies (Group 3452 ± 26.4 vs Group 2436.3 ± 28.4 vs Group 1424.4 ± 24.3 ms, respectively; p < 0.001). Multivariate analysis demonstrated that HCQ/AZT combination (OR 9.02, p = 0.001) and older age (OR 1.04, p = 0.031) were independent predictors of QTc prolongation. The risk increased with age (incremental utility analysis p = 0.02). Twenty patients (18%) died, and no cardiac arrest neither arrhythmic fatalities were documented.

Berzuini,  A,  Bianco, et al

Blood Transfus

Clinical data| Données cliniques

Here we report on blood films examined from 20 patients with COVID-19-related anaemia who had been consecutively referred for pre-transfusion testing or ABO typing.  The analysis of blood smears obtained from patients with COVID-19-related anaemia showed several RBC shape abnormalities. The presence of a high frequency
of stomatocytes and knizocytes, which are not frequently encountered on blood smears in other types of anaemia, were the most common finding. In line with recent
studies, it could be hypothesised that RBC injury occurs as a consequence of immune-mediated mechanisms , and/or physical cell damage due to COVID-19  icroangiopathy.

Analysis of the relationship of the improvement of façades and thermal bridges of spanish building stock with the mitigation of its energy and environmental impact

Energies

Public Health response| Interventions de santé publique

This study assesses the effect of improving building façades and thermal bridges. For this purpose, a case study is assessed for all climate zones in Spain, both in current and future scenarios, considering operational patterns from the COVID-19 pandemic. The study shows that the application of energy conservation measures focusing on reducing the thermal transmittance of façades and the linear thermal transmittance of thermal bridges has a more significant energy and environmental effect than other, more economical energy conservation measures that do not improve the effect of thermal bridges. Likewise, the application of energy conservation measures to improve façades can reduce carbon dioxide emissions but are far from achieving the 90% reduction set by the European Union by 2050. Consequently, these measures should be combined with other measures.

Data Brief

Public Health response| Interventions de santé publique

In this study we focus on physical activity (PA) change in Greek adults over time, during each of the last four weeks of lockdown in Greece. Overall PA change (from PRE to POST condition) ranged from -21.50% in G-I (Ph-I) to -5.03 in G-V (Ph-V); PA change in male subgroups ranged from -26.10% in Ph-I to -13.64 in Ph-V; in female subgroups it ranged from -17.42% in Ph-I to -1.39 in Ph-V. Although the decline in overall PA is evident in all groups during each lockdown phase (p<0.05), the combination of our data demonstrates that towards the end of lockdown this decline showed a gradual decreasing tendency.

The aim of this study was to assess modifications of neuropsychiatric symptoms during quarantine in patients with dementia and their caregivers. A total of 4,913 caregivers participated in the survey. Increased BPSD was reported in 59.6% of patients as worsening of preexisting symptoms (51.9%) or as new onset (26%), and requested drug modifications in 27.6% of these cases. Irritability, apathy, agitation, and anxiety were the most frequently reported worsening symptoms and sleep disorder and irritability the most frequent new symptoms. Profile of BPSD varied according to dementia type, disease severity, and patients’ gender. Anxiety and depression were associated with a diagnosis of AD (OR 1.35, CI: 1.12–1.62), mild to moderate disease severity and female gender. DLB was significantly associated with a higher risk of worsening hallucinations (OR 5.29, CI 3.66–7.64) and sleep disorder (OR 1.69, CI 1.25–2.29), FTD with wandering (OR 1.62, CI 1.12–2.35), and change of appetite (OR 1.52, CI 1.03–2.25).

This study aimed to evaluate the preparedness of Polish pharmacy employees for patient education on the new threat. The study was conducted using the mystery shopper method. Two interviewers phoned 90 randomly chosen community pharmacies throughout Poland and presented some inquiries on the SARS-CoV-2. Pharmacists devoted more time to patients than pharmacy technicians (2:22 vs. 1:54), and the information they provided was significantly more comprehensive (p = 0.006). The majority of respondents provided an evidence-based recommendation on prevention, symptoms, and management of SARS-CoV-2; however, the scope of advice significantly varied. Community pharmacy staff often expressed their concern about the lack of time to address patients’ questions adequately. No statistically significant differences were found in recommendations provided by chain and non-chain pharmacy staff.

Clinical data| Données cliniques Public Health response| Interventions de santé publique

We explored the psychological changes in suspected patients during the COVID-19 epidemic and obtained evidence for early psychological guidance and intervention in this group. A total of 31 inpatients with suspected COVID-19 were identified at our hospital. Among the patients, 32.3% had symptoms of depression and 19.4% had symptoms of anxiety. Levels of anxiety and fear varied. Overall, 50% of confirmed patients had symptoms, with 30.8% classified as mild, 15.4% classified as moderate, and 3.8% classified as severe. During the COVID-19 epidemic, suspected and diagnosed patients had different levels of mental health problems. Diagnosed patients had more visible symptoms. The performance of suspected patients was higher, but their mental state was more polarized. It may thus be important to monitor the psychological state of suspected patients as early as possible to enable timely interventions that promote psychological rehabilitation.

We analyzed the clinical characteristics of COVID-19 fecal/perianal swab nucleic acid-positive patients in our hospital and evaluated the effect of SARS-CoV-2 on the gastrointestinal tract.  Fecal/perianal swabs of 53.61% (52/97) patients were positive including 31 males (59.62%) and 21 females (40.38%). The negative group had more females than males (P = 0.001). The distribution of case classification based on the most severe condition observed after admission was different between groups: five (5.15%) critical type patients were all from the positive group (P = 0.029). There was no statistical difference in clinical manifestations between the groups. In the positive group, the mean nucleic acid-negative conversion time was 14.13 ± 8.61 days, which was significantly later than the negative group (6.98 ± 5.16 days; P < 0.001). In the positive group, 92% (48/52) had nucleic acid-negative conversion with a mean nucleic acid-negative conversion time of 22.58 ± 10.30 days. Among them, 41 (78.85%) cases were delayed compared with pharynx/nasal swab nucleic acid-negative conversion time.

We conducted an online survey of 917 participants to assess the media involvement and other potential factors (empathy, sympathy and affect) which might affect death anxiety. Correlation analysis and mediation models were conducted to examine the relationship between media involvement and death anxiety, and the possible mediating roles of empathy, sympathy, and affect. It was found that media involvement was positively associated with death anxiety. Empathy, sympathy, and negative affect played mediating roles between them. However, empathy and sympathy act differently in the association, as empathy could lead to the increase of negative affect, while sympathy did not.

This paper aims to disclose how the willingness to travel is affected by the risk perception and travellers' familiarity with the destination in a major epidemic. The results show that, under COVID-19, the traveller risk perception is negatively correlated with the willingness to travel, and the traveller familiarity with the destination regulated the negative correlation. It also unveils the traveller risk perception is enhanced by the number of changes of transport vehicles, the length of travel time, and the degree of epidemic impact on the destination, but suppressed by the risk tolerance of potential travellers.

We continuously monitored the serum IgM and IgG responses specific to four SARS-CoV-2 related antigens, including the nucleoprotein (NP), receptor binding domain (RBD), S1 protein, and ectodomain (ECD) of the spike protein among non-severe and severe COVID-19 patients for seven weeks since disease onset. Most patients generated humoral responses against NP and spike protein-related antigens but with their distinct kinetics profiles. Combined detection of NP and ECD antigens as detecting antigen synergistically improved the sensitivity of the serological assay, compared to that of using NP or RBD as detection antigen. 80.7% of convalescent sera from COVID-19 patients revealed that the varying extents of neutralization activities against SARS-CoV-2. S1-specific and ECD-specific IgA responses were strongly correlated with the neutralization activities in non-severe patients, but not in severe patients. Moreover, the neutralizing activities of the convalescent sera were shown to significantly decline during the period between 21 days to 28 days after hospital discharge, accompanied by a substantial drop in RBD-specific IgA response.

Epidemiology| Épidémiologie

This study aimed to understand the distribution patterns and the factors influencing the interval between entry of mainland China and diagnosis in imported COVID-19 cases in Guangdong Province to provide evidence for formulating and implementing effective control measures. A total of 179 imported cases were reported in Guangdong by April 10th, 2020. The average interval between entry of mainland China and diagnosis was 4.21 days with a median of 2 days. The interval was between 1 and 3 days in 69.8% of the cases. Multivariate logistic regression analysis showed that a negative result of the initial nucleic acid test (OR=5.205, 95% CI: 1.100-24.640, P=0.038) and interval between entry of mainland China and a positive diagnosis >2 days (OR=85.654, 95% CI: 24.569-298.615, P < 0.001) were risk factors for the finding delay. The results of initial nucleic acid detection and the interval between entry of mainland China and a positive diagnosis of COVID-19 are the major contributing factors of delayed case detection.

32913273; Humanized single domain antibodies neutralize SARS-CoV-2 by targeting the spike receptor binding domain

Chi,  X,  Liu, et al

Nature communications

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

Here, using SARS-CoV-2 spike receptor-binding domain (RBD) as a bait, we generate a panel of humanized single domain antibodies (sdAbs) from a synthetic library. These sdAbs reveal binding kinetics with the equilibrium dissociation constant (KD) of 0.99-35.5 nM. The monomeric sdAbs show half maximal neutralization concentration (EC50) of 0.0009-0.07 µg/mL and 0.13-0.51 µg/mL against SARS-CoV-2 pseudotypes, and authentic SARS-CoV-2, respectively. Competitive ligand-binding experiments suggest that the sdAbs either completely block or significantly inhibit the association between SARS-CoV-2 RBD and viral entry receptor ACE2. Fusion of the human IgG1 Fc to sdAbs improve their neutralization activity by up to ten times. These results support neutralizing sdAbs as a potential alternative for antiviral therapies.

Running the COVID-19 marathon: the behavioral adaptations in mobility and facemask over 27 weeks of pandemic in Seoul, South Korea

Cho,  Jungwoo,  Shin, et al

arXiv

Public health interventions*| Interventions de santé publique

In this paper, we employ a data-centric approach to investigate individual mobility adaptations and mask-wearing in Seoul, South Korea. We first identify six epidemic phases and two waves based on COVID-19 case count and its geospatial dispersion. The phase-specific linear models reveal the strong, self-driven mobility reductions in the first escalation and peak with a common focus on public transit use and less-essential weekend/afternoon trips. However, comparable reduction was not present in the second wave, as the shifted focus from mobility to mask-wearing was evident. Although no lockdowns and gentle nudge to wear mask seemed counter-intuitive, simple and persistent communication on personal safety has been effective and sustainable to induce cooperative behavioral adaptations. Our phase-specific analyses and interpretation highlight the importance of targeted response consistent with the fluctuating epidemic risk.

This study presents the survey of students' reaction to online classrooms and the adaptability to the online classroom of both students and instructors from the department of industrial engineering, Thammasat University. Students' feedback was collected after the first week of online classroom. The result shows that, in the beginning, there were several problems reported from students, such as the confusion of different platforms used among all courses, sense of isolation, lack of equipment of students, and limited skills of using the online teaching platform of instructors. The most recommended online classroom platforms by students are Zoom for online meetings and Microsoft Teams for learning management systems. It seems that the most concern for students is lacking peer interaction and the learning atmosphere as provided in the traditional classroom.

In March 2020, we observed an outbreak of COVID-19 among a relatively homogenous group of 199 young (median age 21 years; 87% men) Swiss recruits. By comparing physical endurance before and in median 45 days after the outbreak, we found a significant decrease in predicted maximal aerobic capacity in COVID-19 convalescent but not in asymptomatically infected and SARS-CoV-2 naive recruits. This finding might be indicative of lung injury after apparently mild COVID-19 in young adults.

Public health interventions*| Interventions de santé publique

This study examined how these lockdown measures due to COVID-19 changed the incidence of other infectious diseases. The incidence of common and serious infectious diseases in the period 1.01.2020 to 15.05.2020 was evaluated and compared to the corresponding period from the year 2019. A significant drop in the number of reported infectious diseases can be seen in the middle and at the end of March. These observations correlate with the time of introducing social distancing in Poland.

Public Health response| Interventions de santé publique

On March 8, 2020, there was a 650% increase in Twitter retweets using the term “Chinese virus” and related terms. On March 9, there was an 800% increase in the use of these terms in conservative news media articles. Using data from non-Asian respondents of the Project Implicit “Asian Implicit Association Test” from 2007–2020 (n = 339,063), we sought to ascertain if this change in media tone increased bias against Asian Americans. This research provides evidence that the use of stigmatizing language increased subconscious beliefs that Asian Americans are “perpetual foreigners.”

Research Square prepub

Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

We aimed to develop a one-step droplet digital RT-PCR (RT-ddPCR) multiplex assay that allows for sensitive detection of SARS-CoV-2 RNA with respect to human derived RNA. Assay sensitivity of the RT-PCR assay drastically decreased when SARS-CoV-2 copies were detected in a background of total NA extract compared to water, while the sensitivity of the RT-ddPCR was not affected by the total NA background. The present study describes a robust and sensitive one-step RT-ddPCR multiplex assay for reliable detection and quantification of SARS-CoV-2 RNA.

Research Square prepub

Epidemiology| Épidémiologie Immunology | Immunologie

Two seropravelence studies were undertaken in Delhi to test for SARS-CoV-2 antibodies. The survey conducted June 26-July 10 (sample size 21387) showed 23.48% seroprevalence, which was 79-times higher than corresponding virus-tested positives. Survey conducted August 1-7 (15311 samples) showed 29.1% antibody-positive, and was 44x of virus-tested positive total. This study seeks to examine why the multiple should decline so drastically in one month, from 79x to 44x. The study indicates that there is a significant proportion of pre-existing cross-reactive antibodies (possibly to the HCoV viruses), that are seropositive in SARS-CoV-2 antibody tests, to the extent of 16%-19% of the population.

We hypothesize that, in addition to viral load and host antibody repertoire, host genetic variants also impact vulnerability to infection. Here we apply human induced pluripotent stem cell (hiPSC)-based models and CRISPR-engineering to explore the host genetics of SARS-CoV-2. We demonstrate that a single nucleotide polymorphism (rs4702), common in the population at large, impacts alveolar and neuron infection by SARS-CoV-2 in vitro.

COVID-19 presents more seriously in conjunction with other human disease conditions such as hypertension, diabetes, and lung diseases. We conducted a bioinformatics analysis of COVID-19 comorbidity-associated gene sets, identifying genes and pathways shared among the comorbidities. Phenotypic analysis of shared genes revealed significant enrichment for immune system phenotypes and for cardiovascular-related phenotypes, which might point to alleles and phenotypes in mouse models that could be evaluated for clues to COVID-19 severity. Through pathway analysis, we identified enriched pathways shared by comorbidity datasets and datasets associated with SARS-CoV-2 infection.

32913365; Monitoring trends and differences in COVID-19 case-fatality rates using decomposition methods: Contributions of age structure and age-specific fatality

Dudel,  C,  Riffe, et al

PloS one

Epidemiology| Épidémiologie

We analyze the contribution of two key determinants of the variation in the observed case-fatality rate (CFR): the age-structure of diagnosed infection cases and age-specific case-fatality rates. We use data on diagnosed COVID-19 cases and death counts attributable to COVID-19 by age for China, Germany, Italy, South Korea, Spain, the United States, and New York City. The age-structure of detected cases often explains more than two-thirds of cross-country variation in the CFR.  The importance of the age-structure of confirmed cases likely reflects several factors, including different testing regimes and differences in transmission trajectories; while increasing age-specific case-fatality rates in Italy could indicate other factors, such as the worsening health outcomes of those infected with COVID-19.

In this paper, we provide a theoretical framework for the analysis and prediction of the infection rate evolution in time due to the CoVid-19 spreading. By comparison with the theories of growth and recovery in coupled socio-medical systems, we find that the data for many countries show infection rate trends that are exponential in form. In particular, the recovery trajectory is universal in trend and consistent with the learning theory, which allows for predictions useful in the assistance of decision-making of emergency recovery actions.

Here, we compared the performance of two commercial assays, the cobas® SARS-CoV-2 (Roche Diagnostics) and Xpert® Xpress SARS-CoV-2 (Cepheid®) tests, and a laboratory developed RT-PCR test adapted for use on the Hologic® Panther Fusion® (Hologic®) instrument as well as Bio-Rad and QIAGEN real-time PCR detection systems. Due to assay-specific differences in sample processing and nucleic acid extraction, the overall analytical sensitivity ranged from 24 copies/mL specimen to 574 copies/mL specimen. Despite these differences, there was 100 % agreement between the commercial and laboratory developed tests. No false-negative or false-positive SARS-CoV-2 results were observed and there was no cross-reactivity with common respiratory viruses, including endemic coronaviruses.

Angiotensin receptor blockers (ARBs) reducing inflammation and protecting lung and brain function, could be of therapeutic efficacy in COVID-19 patients. Methods: Using GSEA, we compared our previous transcriptome analysis of neurons injured by glutamate and treated with the ARB Candesartan (GSE67036) with transcriptional signatures from SARS-CoV-2 infected primary human bronchial epithelial cells (NHBE) and lung postmortem (GSE147507), PBMC and BALF samples (CRA002390) from COVID-19 patients. Results: Hundreds of genes upregulated in SARS-CoV-2/COVID-19 transcriptomes were similarly upregulated by glutamate and normalized by Candesartan. Gene Ontology analysis revealed expression profiles with greatest significance and enrichment, including proinflammatory cytokine and chemokine activity, the NF-kappa B complex, alterations in innate and adaptive immunity, with many genes participating in the COVID-19 cytokine storm.

32791492; Excess Patient Visits for Cough and Pulmonary Disease at a Large US Health System in the Months Prior to the COVID-19 Pandemic: Time-Series Analysis

Elmore,  JG,  Wang, et al

Journal of medical Internet research

Surveillance

The aim of this study is to investigate whether excess visits where the word "cough" was present in the EHR (USA) reason for visit, and hospitalizations with acute respiratory failure were more frequent from December 2019 to February 2020 compared with the preceding 5 years. The percentage of patients presenting with an EHR reason for visit containing the word "cough" to clinics exceeded the 95% prediction interval the week of December 22, 2019, and was consistently above the 95% prediction interval all 10 weeks through the end of February 2020. Similar trends were noted for emergency department visits and hospitalizations starting December 22, 2019, where observed data exceeded the 95% prediction interval in 6 and 7 of the 10 weeks, respectively. The estimated excess over the 3-month 2019/2020 winter season, obtained by either subtracting the maximum or subtracting the average of the five previous seasons from the current season, was 1.6 or 2.0 excess visits for cough per 1000 outpatient visits, 11.0 or 19.2 excess visits for cough per 1000 emergency department visits, and 21.4 or 39.1 excess visits per 1000 hospitalizations with acute respiratory failure, respectively.  A significantly higher number of patients with respiratory complaints and diseases starting in late December 2019 and continuing through February 2020 suggests community spread of SARS-CoV-2 prior to established clinical awareness and testing capabilities.

We aimed to compare the clinical characteristics and outcomes of COVID-19  schizophrenia (SCZ) patients with those of non-SCZ patients, Marseille, southern France. This study suggests that SCZ is not overrepresented among COVID-19 hospitalized patients, but SCZ is associated with excess COVID-19 mortality, confirming the existence of health disparities described in other somatic diseases. A total of 1092 patients were included. The overall in-hospital mortality rate was 9.0%. The SCZ patients had an increased mortality compared to the non-SCZ patients (26.7% vs. 8.7%, P = 0.039), which was confirmed by the multivariable analysis after adjustment for age, sex, smoking status, obesity and comorbidity (adjusted odds ratio 4.36 95% CI: 1.09–17.44]; P = 0.038). In contrast, the SCZ patients were not more frequently admitted to the ICU than the non-SCZ patients. Importantly, the SCZ patients were mostly institutionalized (63.6%, 100% of those who died), and they were more likely to have cancers and respiratory comorbidities.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

Early Indicators of COVID-19 spread:  The objective of this paper is to specify and examine early indicators of disease spread risk in cities during the initial stages of outbreak based on patterns of human activities obtained from digital trace data.  The results show statistically significant correlations between the indicators of human activities and the basic reproduction number in all counties, as well as a significant leader-follower relationship (time lag) between them. The results also show one to two weeks' lag between the change in activity indicators and the decrease in the basic reproduction number. This result implies that the human activity indicators provide effective early indicators for the spread risk of the pandemic during the early stages of the outbreak.

Clinical data| Données cliniques

We propose that metformin withdrawal in COVID-19 patients be considered to prevent disease progression. We enrolled 110 hospitalized COVID‐19 patients with diabetes under either metformin or non‐metformin hypoglycemic treatment for a case‐control study. There were no differences between the two groups in age, gender, comorbidities, and clinical severity at admission.  Strikingly, the percentage of cases who experienced life-threatening complications was significantly higher in the metformin group (28.6% (16/56) versus 7.4% (4/54), P = 0.004). Antidiabetic therapy with metformin was associated with a higher risk of disease progression in COVID-19 patients with diabetes during hospitalization (adjusted odds ratio = 3.964, 95%CI 1.034-15.194, P = 0.045).  This retrospective analysis suggested a potential safety signal for metformin, the use of which was associated with a higher risk of severe COVID-19.

Hydroxychloroquine is one of several agents being evaluated in the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. March 1 and June 30, 2020. The incidence of active SARS-CoV-2 infections during the study period did not differ between patients receiving hydroxychloroquine and patients not receiving hydroxychloroquine (31 [0·3%] of 10 703 vs 78 [0·4%] of 21 406; odds ratio 0·79, 95% CI 0·52–1·20, p=0·27).  In multivariate logistic regression analysis, receipt of hydroxychloroquine was not associated with the development of active SARS-CoV-2 infection (odds ratio 0·79, 95% CI 0·51–1·42).  There were no significant differences in secondary outcomes between the two groups in patients who developed active SARS-CoV-2 infection. For all patients in the study, overall mortality was lower in the hydroxychloroquine group than in the group of patients who did not receive hydroxychloroquine (odds ratio 0·70, 95% CI 0·55–0·89, p=0·0031).

Objective. To assess the diagnostic yield of point-of-care ultrasound imaging in patients suspected of having noncritical severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection but no apparent changes on a chest radiograph. Methods. Cross-sectional analysis of a case series including patients coming to an emergency department in March and April 2020 with mild-moderate respiratory symptoms suspected to be caused by SARS-CoV-2. A point-of-care ultrasound examination of the lungs was performed on all participants as part of routine clinical care. Ultrasound findings were compared according to the results of SARS-CoV-2 test results. Results. Ultrasound findings were consistent with interstitial pneumonia due to coronavirus disease 2019 (COVID-19) in 33 (56.9%). Most were in cases with test-confirmed COVID-19. The most common ultrasound findings in confirmed COVID-19 cases were focal and confluent B-lines in the basal and posterior regions of the lung and associated pleural involvement.

Disentangling the Impact of the COVID-19 Lockdowns on Urban NO2 From Natural Variability

Goldberg,  DL,  Anenberg, et al

Geophysical Research Letters

Public health interventions*| Interventions de santé publique

TROPOMI satellite data show substantial drops in nitrogen dioxide (NO2) during COVID-19 physical distancing. To attribute NO2 changes to NOx emissions changes over short timescales, one must account for meteorology. We find that meteorological patterns were especially favorable for low NO2 in much of the United States in spring 2020, complicating comparisons with spring 2019. Meteorological variations between years can cause column NO2 differences of ~15% over monthly timescales. After accounting for solar angle and meteorological considerations, we calculate that NO2 drops ranged between 9.2% and 43.4% among 20 cities in North America, with a median of 21.6%. Of the studied cities, largest NO2 drops (>30%) were in San Jose, Los Angeles, and Toronto, and smallest drops (<12%) were in Miami, Minneapolis, and Dallas. These normalized NO2 changes can be used to highlight locations with greater activity changes and better understand the sources contributing to adverse air quality in each city.

. The authors explore the underlying causes for those who intend to defy these norms. Methods: Using national-level data from a March 2020 survey of 989 Americans, the authors explore intentions to defy social distancing norms by testing an interactionist theory of foundation-based moral behavior in combination with faith in President Trump during the coronavirus pandemic. Results: Low self-control is the strongest predictor of defiance intentions. Consistent with interactionist theory, defiance intentions are significantly higher for those holding specific faith in Trump and those endorsing binding foundations.

Baseline T cell immune phenotypes predict virologic and disease control upon SARS-CoV infection

Graham,  Jessica,  Swarts, et al

bioRxiv

Immunology | Immunologie Animal model | Modèle animal

Here, we utilized data from a screen of genetically diverse mice from the Collaborative Cross (CC) infected with SARS-CoV to determine whether circulating baseline T cell signatures are associated with a lack of viral control and severe disease upon infection. SARS-CoV infection of CC mice results in a variety of viral load trajectories and disease outcomes. Further, early control of virus in the lung correlates with an increased abundance of activated CD4 and CD8 T cells and regulatory T cells prior to infections across strains. A basal propensity of T cells to express IFNg and IL17 over TNFa also correlated with early viral control. Overall, a dysregulated, pro-inflammatory signature of circulating T cells at baseline was associated with severe disease upon infection.

Public Health response| Interventions de santé publique

The present study examined how student-athletes’ mental health was associated with teammate social support, connectedness, and changes to athletic identity from before to during COVID-19. Method: A sample of 234 student-athletes completed surveys before COVID-19 physical distancing (February 2020), with 135 (63% female) participating in a follow-up in the month following school closures (April 2020). Path models estimated the effects of teammate social support and connectedness (during COVID-19), as well as changes in athletic identity on indices of mental health. Results: student-athletes who received more social support and reported more connectedness with teammates reported less dissolution of their athletic identity and—in most models—reported better mental health and well-being.

The objective of this study is to present an epidemic model specially tailored for the study of the COVID-19 epidemics, and the model is aimed at allowing the integrated study of epidemic control strategies and dimensioning of the required medical infrastructure. Along with the theoretical model, a case study with three prognostic scenarios is presented for the first wave of the epidemic in the city of Manaus, the capital city of Amazonas state, Brazil. Although the temporary collapse of the medical infrastructure is hardly avoidable in the state-of-affairs at this time (April 2020), the results show that there are feasible control strategies that could substantially reduce the overload within reasonable time. Furthermore, this study delivers and presents an intuitive, straightforward, free, and open-source online platform that allows the direct application of the model.

OBJECTIVE: The aim of this study was to analyze the benefits of using telemedicine services for patients with chronic liver disease (CLD) at a tertiary care center in Italy during the COVID-19-mandated lockdown. METHODS: From March 9 to May 3, 2020, a prospective observational study was conducted in the Liver Unit of the University Hospital of Naples Federico II to evaluate the impact of (1) a fully implemented telemedicine program, partially restructured in response to COVID-19 to include video consultations; (2) extended hours of operation for helpline services; and (3) smart-working from home to facilitate follow-up visits for patients with CLD while adhering to social distancing regulations. RESULTS: During the lockdown in Italy, almost 400 visits were conducted using telemedicine; only patients requiring urgent care were admitted to a non-COVID-19 ward of our hospital. Telemedicine services were implemented not only for follow-up visits but also to screen patients prior to hospital admission and to provide urgent evaluations during complications.

The current study was conducted in the Basque Autonomous Community in northern Spain. The authors analyzed stress, anxiety, and depression with the arrival of the virus and the levels of symptoms according to age, comorbidity, and confinement. Levels of anxiety, stress, and depression were measured in a sample of 976 adults, using the DASS scale ( Depression Anxiety, and Stress Scale). Although levels of symptoms were generally low at the start of the alert, younger individuals with chronic diseases reported more symptoms than the rest of the population. The study also detected higher levels of symptoms after the stay-at-home order was issued. Such symptoms are predicted to increase as the confinement continues. The authors propose psychological interventions for prevention and treatment in order to mitigate the pandemic's psychological impacts.

We evaluated the protective activity of a chimpanzee adenovirus-vectored vaccine encoding a prefusion stabilized spike protein (ChAd-SARS-CoV-2-S) in challenge studies with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and mice expressing the human angiotensin-converting enzyme 2 receptor.  Intramuscular dosing of ChAd-SARS-CoV-2-S induces robust systemic humoral and cell-mediated immune responses and protects against lung infection, inflammation, and pathology but does not confer sterilizing immunity, as evidenced by detection of viral RNA and induction of anti-nucleoprotein antibodies after SARS-CoV-2 challenge. In contrast, a single intranasal dose of ChAd-SARS-CoV-2-S induces high levels of neutralizing antibodies, promotes systemic and mucosal immunoglobulin A (IgA) and T cell responses, and almost entirely prevents SARS-CoV-2 infection in both the upper and lower respiratory tracts. Intranasal administration of ChAd-SARS-CoV-2-S is a candidate for preventing SARS-CoV-2 infection and transmission and curtailing pandemic spread.

We determined the susceptibility of SARS-CoV-2 to irradiation with ultraviolet light. The virus was highly susceptible to ultraviolet light. A viral stock with a high infectious titer of 5 × 106 TCID50/mL was completely inactivated by UVC irradiation after nine minutes of exposure. The UVC dose required for complete inactivation was 1,048 mJ/cm2. UVA exposure demonstrated only a weak effect on virus inactivation over 15 minutes. Hence, inactivation of SARS-CoV-2 by UVC irradiation constitutes a reliable method for disinfection purposes in health care facilities and for preparing SARS-CoV-2 material for research purpose.

Following the hypothesis that T cells in COVID-19 might have a similar, dual function, we comprehensively characterized the differentiation (CCR7, CD45RO) and activation status (HLA-DR, CD38, CD69, CD226), the co-expression of co-inhibitory molecules (PD1, TIM-3, LAG-3, BTLA, TIGIT), as well as the expression pattern of the transcription factors T-bet and eomes of CD8+ and CD4+ T cells of PBMC of n = 20 SARS-CoV-2 patients compared to n = 10 P. falciparum infected patients and n = 13 healthy controls. Overall, acute COVID-19 and malaria infection resulted in a comparably elevated activation and altered differentiation status of the CD8+ and CD4+ T cell populations.  T effector cells of COVID-19 and malaria patients showed higher frequencies of the inhibitory receptors T-cell immunoglobulin mucin-3 (TIM-3) and Lymphocyte-activation gene-3 (LAG-3) which was linked to increased activation levels and an upregulation of the transcription factors T-bet and eomes. COVID-19 patients with a more severe disease course showed higher levels of LAG-3 and TIM-3 than patients with a mild disease course.

Public Health response| Interventions de santé publique

Methods: Aim of this web-based survey was to assess the mental health burden of the German public over a period of 50 days after the COVID-19 outbreak. 16,245 individuals responded regarding sleep disturbances, COVID-19-fear, and generalized anxiety disorder (GAD-7). Data were put in relation to infection rates, number of deaths and the German stock index. Results: The specific fear increased rapidly in concordance with infection numbers. However, no relation to the number of deaths was found, COVID-19-fear developed reversed to the stock index. Initially, 13.5% of the respondents reported a reduced sleep quality, and 7.2% a moderate generalized anxiety; proceeding simultaneously with high peaks. Finally, more than twice as many respondents showed psychological burdens.

A Relationship Between SIR Model and Generalized Logistic Distribution with Applications to SARS and COVID-19

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

This paper shows that the generalized logistic distribution model is derived from the SIR model under certain conditions. In the SIR model, there are uncertainties in predicting the final values for the number of infected population and the infectious parameter. However, by utilizing the information obtained from the generalized logistic distribution model, we can perform the SIR numerical computation more stably and more accurately. Applications to SARS and COVID-19 using this combined method are also introduced. We have fitted the generalized logistic distributions to observed values of cumulative number of infected persons, cumulative number of died persons and cumulative number of recovered persons. We see that the infection spreads very quickly, but recovered slowly. From the infection to recover, it took three weeks referring the median time of infection curve and recovered curve.

We analyze the potential of using TB diagnostic and research infrastructures for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing. We focused on quality control by adapting the 12 Quality System Essentials framework to the COVID-19 and TB context. We conclude that diagnostic infrastructures for TB can in principle be leveraged to scale-up SARS-CoV-2 testing, in particular in resource-poor settings. TB research infrastructures also can support sequencing of SARS-CoV-2 to study virus evolution and diversity globally.

Our group applied an unsupervised machine learning technique to identify COVID-19 cases.   Our experiments utilize Principal Component Analysis (PCA), t-distributed Stochastic Neighbor Embedding (t-SNE), and the recently developed Robust Continuous Clustering algorithm (RCC). We display the performance of RCC in identifying COVID-19 patients and its ability to compete with other unsupervised algorithms, namely K-Means++ (KM++). Using a COVID-19 Radiography dataset, we found that RCC outperformed KM++; we used the Adjusted Mutual Information Score (AMI) in order to measure the effectiveness of both algorithms. The AMI for the two and three class cases of KM++ were 0.0250 and 0.054, respectively. In comparison, RCC scored 0.5044 in the two class case and 0.267 in the three class case, clearly showing RCC as the superior algorithm.

Non-pharmaceutical interventions (NPIs) are effective in curbing the spread of severe acute respiratory syndrome coronavirus 2. All US states have adopted NPI policies, but the compliance to these measures and influence of sociopolitical factors on NPI adherence is unknown. NPI adherence may be approximated by personal mobility in a population that is tracked by anonymous mobile phone data. Study design: This is a cross-sectional study of state-level mobility changes across the US. Methods: State-level mobility was based on anonymous mobile phone data from multiple participating carriers collected by the University of Washington's Institute for Health Metrics and Evaluation. Results: All states experienced a decline in personal mobility but had varying nadirs ranging from a 34% to a 69% reduction in mobility, which was not temporally related to the timing of state-level NPI measures. There was a statistically significant linear and negative correlation (r = −0.79) between the proportion of Republicans/leaning Republicans and NPI adherence across US states. The negative association between Republicans and NPI adherence was significant even when adjusting for urbanization, proportion of essential workers, population, Gini index, and poverty rates.

METHODS: We invited the participants from Hubei and Henan Provinces of China for an internetbased survey starting from 12:00 on February 21, 2020 to 12:00 on February 23. The survey included the general conditions, KAP of COVID-19, psychological status and living conditions of the residents. RESULTS: Social media were the most important source of information concerning the pandemic of the respondents. The respondents had a high awareness of person-to-person transmission of the virus through the respiratory tract or droplets but showed a relatively low level of awareness of the population susceptible to COVID-19 and its specific symptoms. The results of multivariate analysis showed that women, undergraduate students (including college students) and higher degree holders had better knowledge of COVID-19. the proportion of respondents who expressed to have different levels of psychological stressed such as worry, anxiety and panic reached 77.2%; 16.7% of the responders considered psychological interventions necessary for their psychological conditions; 63.6% of the respondents confessed a bias against the people returning from Hubei and Henan provinces, while 22.4% worried that they might be biased because of their residence in Hubei and Henan.

This study aimed to detect pathogens in biological and environmental samples of these asymptomatic infected individuals and analyse their association. Using a cross-sectional study design, we collected biological and environmental samples from 19 patients treated in the isolation ward of Nanjing No.2 Hospital. As results, 19 asymptomatic infected individuals participated in the survey, with 8 positives for pathogens and 11 positives only for antibodies. Three positive samples were detected from among 96 environmental samples, respectively, from a cell phone surface, a cell phone shelf and a bedside handrail. No positive samples were detected in the exhaled breath condensate in this work. All patients identified pathogens in the environment had positive anal swabs. There was a statistical association between positive anal swabs and positive environmental samples. The association of positive samples from the surrounding of asymptomatically infected patients with positive anal swabs suggested that patients might secrete the virus for a more extended period.

We report a series of 17 consecutive patients with profound B-cell lymphopenia and prolonged COVID-19 symptoms, negative IgG-IgM SARS-CoV-2 serology and a positive RNAemia measured by digital PCR who were treated with four units of COVID-19 convalescent plasma. Within 48 hours following transfusion, all patients except one experienced an amelioration of their clinical symptoms. The inflammatory syndrome abated within a week. Only one patient who needed mechanical ventilation for severe COVID-19 disease died of bacterial pneumonia. SARS-CoV-2 RNAemia decreased to below the sensitivity threshold in 9 out of 9 evaluated patients. Analysis of virus-specific T-cell responses using T-cell enzyme linked immunoSpot (ELISPOT) assay was analyzed before convalescent plasma transfusion in 3 patients. All showed a conserved SARS-CoV-2 T-cell response and poor cross-response to other coronaviruses. No adverse event was reported.

On the verge of life: Distribution of nucleotide sequences in viral RNAs

Husev,  Mykola,  Rovenchak, et al

arXiv

Coronavirology| Coronavirologie

The aim of the study is to analyze viruses using parameters obtained from distributions of nucleotide sequences in the viral RNA. Seeking for the input data homogeneity, we analyze single-stranded RNA viruses only. Two approaches are used to obtain the nucleotide sequences; In the first one, chunks of equal length (four nucleotides) are considered. In the second approach, the whole RNA genome is divided into parts by adenine or the most frequent nucleotide as a "space". Rank--frequency distributions are studied in both cases. Within the first approach, the Pólya and the negative hypergeometric distribution yield the best fit. For the distributions obtained within the second approach, we have calculated a set of parameters, including entropy, mean sequence length, and its dispersion. The calculated parameters became the basis for the classification of viruses. We observed that proximity of viruses on planes spanned on various pairs of parameters corresponds to related species. In certain cases, such a proximity is observed for unrelated species as well calling thus for the expansion of the set of parameters used in the classification. We also observed that the fourth most frequent nucleotide sequences obtained within the second approach are of different nature in case of human coronaviruses (different nucleotides for MERS, SARS-CoV, and SARS-CoV-2 versus identical nucleotides for four other coronaviruses).

This cross-sectional study aims to assess the knowledge, attitude, and practices regarding COVID-19 among people with chronic diseases at the outpatient departments in Ho Chi Minh City. A total of 522 participants had a mean age of 51.5 ± 10.6 years. Most of them reported seeing information regarding the COVID-19 pandemic (93.7%) via television and social media (72.8% and 62.1%, respectively). Just over two-thirds of the participants (68.4%) answered with sufficient knowledge of COVID-19. Most respondents had a positive attitude toward COVID-19 (90.8%), although some misconceptions existed. Almost over three-fourths of them (77.2%) maintained good practices for prevention. The rate of good practices in those who had sufficient knowledge was 1.24 times greater than that among those who had insufficient knowledge (PR 1.24, 95% CI: 1.10–1.41, P<0.05). Also, the rate of good practices in males was lower than that of females (PR: 0.91, 95% CI: 0.83–0.99, P<0.05).

Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

After fully characterising lentiviral pseudotypes bearing the SARS-CoV-2 spike protein, we employed them in pseudotype-based neutralisation assays in order to profile the neutralising activity of human serum samples from an Italian sero-epidemiological study. The results obtained with pseudotype-based neutralisation assays mirrored those obtained when the same panel of sera was tested against the wild type virus, showing an evident convergence of the pseudotype-based neutralisation and MN results. The overall results lead to the conclusion that the pseudotype-based neutralisation assay is a valid alternative to using the wild-type strain, and although this system needs to be optimised and standardised, it can not only complement the classical serological methods, but also allows serological assessments to be made when other methods cannot be employed, especially in a human pandemic context.

Modelling/ prediction| Modélisation/prédiction Transmission

This paper aims to establish a performance evaluation of Multilayer Perceptron (MLP) and a Radial Basis Function (RBF) networks in investigating the contributing factors for COVID-19 spread and death. The RBF and MLP networks are typically used in the same form of applications, however, their internal calculation structures are different. A comparison was made by using a dataset of COVID-19 cases in 41 Asia countries during April 2020. There are nine contributing factors which acted as the covariates to the network such as Cases, Deaths, High Temperature, Low Temperature, Population, Percentage of Cases over Population, and Percentage of Death over Population, Average Temperature, and Total Cases. The results obtained from the testing sets indicated that the two neural structures were able to investigate the COVID-19 spread and death contributing factors. Nevertheless, the RBF network indicated a slightly better performance than the MLP.

Epidemiology| Épidémiologie

This  preliminary study investigates whether trace lithium, such as that in drinking water, may be associated with a low COVID-19 mortality. After adjusting for the relevant factors using a stepwise method, the model could predict COVID-19 standard mortality rates (SMRs) with statistical significance (F=42.1, p<0.001). However, the lithium level was not a significant contributor to the COVID-19 SMR (B=0.073, p=0.367). Among the relevant factors, only the proportion of elderly people (B=0.629 p<0.001) and the proportion of one-person households (B-0.334 p=0.002) were significant contributors.

Forty patients were included (median age, 30 years; interquartile range IQR], 25-57 years; 58% female). Six (15%) patients required supplemental oxygen. The prevalence of asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection was 5% and that of presymptomatic infection was 13%. Cough, fever, myalgia, rhinorrhea or nasal congestion, and diarrhea were the screening criteria for diagnosing symptomatic and presymptomatic SARS-CoV-2 infections. Sputum production, chest discomfort, a large number of symptoms, abnormal procalcitonin and C-reactive protein levels, and abnormal chest X-ray or chest computed tomography findings were more common in patients requiring supplemental oxygen than in those not requiring supplemental oxygen. Overall mortality rate was 3% (1/40). Four patients (10%) were readmitted after testing positive by reverse-transcription polymerase chain reaction again. Incubation period was 5 days (IQR, 4-6 days), and the duration of viral shedding was 21 days (IQR, 14-28 days; maximum, 51 days).

This study aimed to investigate chemical characteristics, abatement mechanisms and regional transport of atmospheric pollutants during the COVID-19 outbreak control period in the Yangtze River Delta (YRD) region, China. Due to the stricter outbreak control, the levels of PM2.5 and VOCs, and the occurrence frequencies of haze-fog episodes decreased substantially from NCP to CP, with average reduction rates of 31.6%, 38.9% and 35.1% at PD, and 34.5%, 50.7% and 37.9% at DSL, respectively. The major source for PM2.5 was secondary sulfate & nitrate in both periods, and the emission control of primary sources such as coal burning and vehicle exhaust decreased the levels of precursors gas sulfur dioxide and nitrogen oxide, which highly contributed to the abatement of PM2.5 from NCP to CP. The higher levels of ozone at both PD and DSL on CP might be due to the weak nitrogen monoxide titration, low relative humidity and high visibility compared with NCP. Vehicle exhaust and fugitive emission from petrochemical industry were the major contributors of ambient VOCs and their decreasing activities mainly accounted for VOCs abatement. Moreover, the high frequency of haze-fog events was closely impacted by medium-scale regional transport within Anhui and Jiangsu provinces.

The study of alterations in the epidemiological pattern of traumatic injuries during the COVID-19 crisis can provide estimates in the planning of healthcare resources.  There were important epidemiological changes during the COVID-19 crisis in trauma patients. The cessation of sports activities resulted in a reduction in ligamentous injuries of sports origin. Women better implemented the stay-at-home strategies shown by a sudden increase in the men to women ratio of risk-taking traumatic injuries. The decreased number of patients with soft-tissue injuries and a high rate of self-discharge must inform the authorities of the fear of in-hospital contamination.

To elucidate the cardiotoxicity induced by  CQ and AZM , authors examined the effects of these drugs based on the electrophysiological properties of human embryonic stem cell-derived cardiomyocytes (hESC-CMs) using multi-electrode arrays. In support of the clinical data suggesting the cardiovascular side effects of the combination therapy of CQ and AZM, our results suggest that AZM reinforces the cardiotoxicity induced by CQ in hESC-CMs.

Clinical data| Données cliniques

COVID-19 is a new disease leading to respiratory complications in adults. Children appear to have more modest symptoms than adults. Varicella is often described as a benign disease in the pediatric population. However, patients with varicella and COVID-19 co-infection can develop a more serious respiratory infection. We report the case of an infant who had a co-infection with both viruses that led to pleuropneumonia. The main question in the present case concerns the link between COVID-19 and varicella infection, and the possible modulation in immune response due to the two virus infections. © 2020 French Society of Pediatrics

Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

We examined national all-cause mortality comparing weeks 1–27 in 2020 and 2015–2019. We examined all-cause mortality rates among all deaths recorded from 2015 to 2020 and among chronic conditions (cardiovascular (cardiac & circulatory), chronic pulmonary, chronic kidney disease, cancer, and diabetes), comparing each week in 2020 to weeks in 2015–2019. During the COVID-19 pandemic, due to timely lockdown measures, the mortality rate in Denmark has not increased compared to the mortality rates in the same period during 2015–2019.

Evaluation of Boarding Methods Adapted for Social Distancing When Using Apron Buses

Milne,  RJ,  Delcea, et al

IEEE Access

Modelling/ prediction| Modélisation/prédiction Public health interventions*| Interventions de santé publique

We conduct stochastic simulation experiments to assess nine adaptations of boarding methods according to four performance metrics. Three of the metrics are related to the risk of the virus spreading to passengers during boarding. The fourth metric is the time to complete boarding of the two-door airplane when apron bus transport passengers to the airplane. The particular adaptation to use depends on an airline’s relative preference for having short boarding times versus a reduced risk of later boarding passengers passing (and thereby possibly infecting) previously seated window seat passengers.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We used the extended form of the Susceptible-Exposed-Infected/Infectious-Recovered/Removed (SEIR) model to predict new cases and number of deaths associated to COVID-19 in Iran. The total DALYs for COVID-19 in Iran predicted by our model will be 973 per 100,000 populations from January, 2020 to January, 2021. Our predictions of COVID-19 burden will be useful in determining health priorities and to appropriately allocate resources to prepare for future outbreaks of COVID-19 and similar diseases. We hope this study will contribute to evidence-based health policy making in Iran.

Canadian Public Policy

Public Health response| Interventions de santé publique

To examine how mask usage by Canadians changed in the months since the onset of the pandemic in Canada, we use data from the Vox Pop Labs (2020) COVID-19 Monitor initiative, a rolling public opinion survey that has been fielded weekly since mid-March.  We analyze the first 12 waves of the study, which were conducted between 20 March and 3 June and involved 27,040 respondents. Despite the policy reversal on masks by Canadian public health officials, the survey data collected from the COVID-19 Monitor indicate that Canadians were responsive to changing guidance, self-reported usage rises from 5 percent in late March to 63 percent by early June.  Notably, the inflection point appears to take place in early April and corresponds with the issuance of revised guidance on masks by PHAC.

To present the otologic findings of a patient with COVID-19 and complicated acute otitis media, evaluate for the presence of SARS-CoV-2 in middle ear fluid, and assess whether suctioning of middle ear fluid may be aerosol- generating. Consistent with observations during endonasal suctioning, suctioning of middle ear fluid was not found to be aerosol or droplet generating. While middle ear suctioning may not be aerosol-generating, the risk of coughing or prolonged close contact requires heightened precautions during otologic procedures in patients with suspected or confirmed COVID-19

Epidemiology| Épidémiologie Clinical data| Données cliniques

Patients hospitalized for infection with SARS-CoV-2 typically present with pneumonia. The respiratory failure is frequently complicated by pulmonary embolism in segmental pulmonary arteries. The distribution of pulmonary embolism in regard to lung parenchymal opacifications has not been investigated yet. Methods: All patients with COVID-19 treated at a medical intensive care unit between March 8th and April 15th, 2020 undergoing computed tomography pulmonary angiography (CTPA) were included. All CTPA were assessed by two radiologists independently in respect to parenchymal changes and pulmonary embolism on a lung segment basis. Results: Out of 22 patients with severe COVID-19 treated within the observed time period, 16 (age 60.4 ± 10.2 years, 6 female SAPS2 score 49.2 ± 13.9) underwent CT. A total of 288 lung segment were analyzed. Thrombi were detectable in 9/16 (56.3%) patients, with 4.4 ± 2.9 segments occluded per patient and 40/288 (13.9%) segments affected in the whole cohort. Patients with thrombi had significantly worse segmental opacifications in CT (p < 0.05) and all thrombi were located in opacitated segments. There was no correlation between d-dimer level and number of occluded segmental arteries. Conclusions: Thrombi in segmental pulmonary arteries are common in COVID-19 and are located in opacitated lung segments. This might suggest local clot formation.

Healthcare Response | Réponse des soins de santé

In an effort to improve the efficiency of computer algorithms applied to screening for coronavirus disease 2019 (COVID-19) testing, we used natural language processing and artificial intelligence-based methods with unstructured patient data collected through telehealth visits. Text analytics revealed that concepts such as smell and taste were more prevalent than expected in patients testing positive. As a result, screening algorithms were adapted to include these symptoms. The deep learning model yielded an area under the receiver-operating characteristic curve of 0.729 for predicting positive results and was subsequently applied to prioritize testing appointment scheduling. Informatics tools such as natural language processing and artificial intelligence methods can have significant clinical impacts when applied to data streams early in the development of clinical systems for outbreak response.

Objective: to model disease progression, healthcare demand and case fatality rate attributed to COVID-19 pandemic that may occur in Chile in 1-month time, by simulating different scenarios according to diverse mitigation measures hypothetically implemented. If no mitigation measures were applied (R0=2.5), by May 25, Chile would have 2 019 775 cases and 15 068 deaths. If mitigations measures were implemented to decrease R0 to 1.5 (early detection of cases, quarantine, social distancing of elderly), the number of cases and deaths would importantly decrease. Nonetheless, the demand for in-hospital care including intensive care would exceed the available resources. Our age-specific analysis showed that population over 60 years are at higher risk of needing intensive care and death.

Assess the situation and perception of the Spanish population in four key areas related to the COVID-19 pandemic: social contact behavior during confinement, personal economic impact, labor situation, and health status. Regarding social behavior during confinement, participants mainly left their homes to satisfy basic needs. We found several statistically significant differences in social behavior across genders and age groups. The population's willingness to comply with the confinement measures is evident. From the survey answers, we identified a significant adverse economic impact of the pandemic on those working in small businesses and a negative correlation between economic damage and willingness to stay in confinement. The survey revealed that close contacts play an important role in the transmission of the disease, and 28% of the participants lacked the necessary resources to properly isolate themselves. We also identified a significant lack of testing, with only 1% of the population tested and 6% of respondents unable to be tested despite their doctor's recommendation. We developed a generalized linear model to identify the variables that were correlated with a positive SARS-CoV-2 test result; estimated an average of 5% for SARS-CoV-2 prevalence in the Spanish population. .

Public Health response| Interventions de santé publique

1,073 Canadian workers working full-/part-time or who were temporarily laid off completed an online survey, including measures of wellbeing at work or in general, job security and potential resilience levers (workplace disaster preparedness, policy, social capital). Multiple regression findings highlight that marginalized workers (e.g., women, migrants, people facing financial hardships) reported lower job security, and having temporarily lost one’s job was negatively associated with job security. Low job security was related to lower scores across measures of wellbeing. Distress was high in the sample. Workplace disaster preparedness, policy and social capital were associated with higher wellbeing. The effects of these resilience levers tended to be stronger at higher job security levels.

Serial simultaneously self-swabbed samples from multiple sites show similarly decreasing SARS-CoV-2 loads in COVID-19 cases of differing clinical severity

Clinical data| Données cliniques Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

Shortly after a confirmed diagnosis of COVID-19 using the local diagnostic AusDiagnostics (Ausdiagnostics UK Ltd., Chesham, England) SARS-CoV-2 PCR test,3 each participant volunteered to provide serial self-collected swabs from the nasopharynx (NPS, 1 swab), just inside the soft part of the nose (NS, 1 swab), the oropharynx (OPS, 1 swab), inside the cheek (CS, 1 swab). In addition, we also decided to check for the presence of SARS-CoV-2 in the conjunctiva (CJS, 1 swab for both eyes).  From 17th April to 5th May 2020, a total of 105 swabs were collected from three participants.  All three participants were PCR negative for SARS-CoV-2 on the final swabs taken on 5th May 2020. Patient 1 (mild COVID-19) only had positive PCR results from the NPS and NS, with negative PCR results from the NS after day 8. Patient 2 had positive PCR results from all sites except for the conjunctiva, with the lowest cycle threshold (Ct) value (i.e. the highest viral load) in the NPS, followed by the OPS, NS and CS. Patient 3 had positive PCR values from all sites; with the lowest Ct value (highest viral load) in the NPS followed by NS, CS, OPS and CJS. For all three participants, Ct values appeared to increase (i.e. the viral loads decreased) over time.  self-swabbing from these various URT sites is an effective and sensitive way to collect diagnostic samples, as found elsewhere. we conclude that for symptomatic patients, it is difficult to obtain a ‘false negative’ result on NPS, OPS, NS or CS samples, if sampled early (within 5 days) post-symptom onset, even if the swab was ‘poorly’ taken.

We collected daily numbers of COVID-19 cases in 202 locations in 8 countries. We matched meteorological data from the NOAA National Centers for Environmental Information. Temperature did not exhibit significant association with R0 of COVID-19 (meta p = 0.446). Also, relative humidity (meta p = 0.215), wind speed (meta p = 0.986), and ultraviolet (UV) radiation (meta p = 0.491) were not significantly associated with R0 either.

Public health interventions*| Interventions de santé publique

This study compared the surface air quality monitoring data from the United States Environmental Protection Agency (U.S. EPA)'s AirNow network during the period 20 March-5 May in 2020 to those in 2015-2019 from the Air Quality System (AQS) network over the state of California. The results indicated changes in fine particulate matter (PM2.5) of-2.04 ± 1.57 μg m-3 and ozone of-3.07 ± 2.86 ppb. If the air quality improvements persist over a year, it could potentially lead to 3970-8900 prevented premature deaths annually (note: the estimates of prevented premature deaths have large uncertainties). Public transit demand showed dramatic declines (~80%). The pandemic provides an opportunity to exhibit how substantially human behavior could impact on air quality.

Epidemiology| Épidémiologie Clinical data| Données cliniques

Out of 98 patients admitted to a dedicated COVID-19 ICU at the University Hospital of Bari with diagnosis of ARDS, 18 consecutive patients (from March 18 to May 12, 2020) were included in a thorough evaluation over time aiming to assess the changes of several reliable clotting variables in order to determine the nature of the coagulopathy associated with COVID-19 and its relationship with inflammation. Our data show that patients with COVID-19 display marked alterations of the coagulation system, which, however, are not compatible with a consumption coagulopathy typical of DIC.  we found that the main change in COVID-19 patients is the rise in D-dimer and fibrinogen levels. On the contrary, platelets, PT and PTT were within the normal range and their trajectories over the whole follow-up did not show any sign of consumption.

This study explores the demographic and environmental factors affecting the spread and mortality rate of COVID-19 in countries around the world.  We found that countries with a higher proportion of people over 65 had a higher rate of confirmed positive cases, a higher mortality rate, and a higher case fatality rate. We also found that there was a positive and significant statistical correlation between the number of foreign migrants in a country and the rate of confirmed positive COVID19 cases and the number of deaths but an inverse relationship between this variable and the case fatality rate. We found a negative relationship between the number of hospital beds and mortality and case fatality rate while but a positive relationship between the level of nitrogen oxides in the environment and the rate of confirmed positive cases, the mortality rate, and the case fatality rate, although there was no such relationship for ultrafine dust.

From May 2nd to 26th June 2020, we tested with the Abbott SARS-CoV-2 IgG assay 3569 staff HCWs (female, 74.8 %; median age, 39.6 years) in the hospital department of occupational medicine, on a voluntary basis. SARS-CoV-2 IgG antibodies were detected in 423 (11.9%) HCWs. A. A total of 90 (2.5 %) HCWs with equivocal Abbott index values were further retested with Beckman Coulter IgG assay: 70 were SARS-CoV-2 IgG-negative, 6 showed equivocal results, and 14 (15.5 %; 0.4 % of HCWs) were SARS-CoV-2 IgG-positive. The combination strategy of two SARS-CoV-2 IgG assays having different targets in series with final interpretation given by the second test was used to address the issues of HCWs with equivocal results by the first test. In our series, such strategy made possible to recover 14 sera having index values in the Abbott equivocal zone.

This work intent to develop the CNN model by the process of transfer learning. The models will be created from the three pre-trained models include Xception, VGG16, and Inception-Resnet-V2 model. Then, these newly proposed models will be applied to detect COVID-19 pneumonia from the X-ray image dataset. The proposed models enhance to diagnose the chest X-ray images of patients who have pneumonia by COVID-19. Since the existing COVID-19 X-ray dataset has a small number of images containing 323 images, this work uses the data augmentation techniques to increase the virtual number of images. The results reveal that the proposed models have performed the classification task for detecting pneumonia. The proposed model achieved an accuracy level of Xception, VGG16, and Inception-Resnet-V2 is 97.19%, 95.42% and 93.87%, respectively.

We compared cytokine, humoral, and cellular immune responses in pediatric (children and youth, age < 24 years) (n=65) and adult (n=60) patients with COVID-19 at a metropolitan hospital system in New York City. The pediatric patients had a shorter length of stay, decreased requirement for mechanical ventilation and lower mortality compared to adults. The serum concentrations of IL-17A and IFN-γ, but not TNF-α or IL-6, were inversely related to age. Adults mounted a more robust T cell response to the viral spike protein compared to pediatric patients as evidenced by increased expression of CD25+ on CD4+ T cells and the frequency of IFN-γ+CD4+ T cells. Moreover, serum neutralizing antibody titers and antibody-dependent cellular phagocytosis were higher in adults compared to pediatric COVID-19 patients. The neutralizing antibody titer correlated positively with age and negatively with IL-17A and IFN-γ serum concentrations. There were no differences in anti-spike protein antibody titers to other human coronaviruses.

METHODS: Starting March 1st, 332 patients were introduced to a RM program during the Italian lockdown in order to limit the risk of in-hospital exposure to Severe Acute Respiratory Syndrome-Coronavirus-2. Patients were categorized into two groups based on the modality of RM delivery home (n=229) vs office (n= 103) delivered]. The study aimed at assessing the efficacy of the new follow-up protocol, assessed as mean RM Activation Time (AT) and need for technical support.  Results: Activation Time (AT) time was <48 hours in 93% of patients and 7% of them required further technical support. Despite a higher number of trans‐telephonic technical support in home‐delivered Remote monitoring (RM) group, mean AT was similar between groups (1.33±0.83 days in home‐delivered vs 1.28±0.81 days in office‐delivered patients; p=0.60). Twenty‐eight (2.5%) urgent/emergent in‐person examinations were required. A high degree of patient satisfaction was reached in both groups whereas anxiety status was higher in office‐delivered group.

we aimed to investigate associations of Vitamin D (VITD) status to disease presentation within the CovILD registry. A total of 109 patients were included in the analysis (60% males, 40% females), aged 58 ± 14 years. Eight weeks after the onset of COVID-19, a high proportion of patients presented with impaired VITD metabolism and elevated parathyroid hormone (PTH) levels. PTH concentrations were increased in patients who needed intensive care unit (ICU) treatment, while VITD levels were not significantly different between disease severity groups. Low VITD levels at disease onset or at eight-week follow-up were not related to persistent symptom burden, lung function impairment, ongoing inflammation, or more severe CT abnormalities. VITD deficiency is frequent among COVID-19 patients but not associated with disease outcomes. However, individuals with severe disease display a disturbed parathyroid-vitamin-D axis within their recovery phase.

RNA and protein sequences obtained from databases were used to count the number of atoms of each element in the virions of SARS, MERS and SARS-CoV-2. The number of protein copies and carbohydrate composition were taken from the literature. The number of lipid molecules was estimated from the envelope surface area. Based on elemental composition, growth equations were balanced, and thermodynamic properties of the viruses were determined using Patel-Erickson and Battley equations. Elemental and molecular compositions of SARS, MERS and SARS-CoV-2 were found, as well as their standard thermodynamic properties of formation and growth. Standard Gibbs energy of growth of virus nucleocapsids was found to be significantly more negative than that of their host tissue. The ratio of Gibbs energies of growth of virus nucleocapsids and host cell is greater than unity. The more negative Gibbs energy of growth of viruses implies that virus multiplication has a greater driving force than synthesis of host cell components, giving a physical explanation of why viruses are able to hijack their host cell's metabolism.

A web-based survey was designed and sent to pediatric exercise testing laboratories in the United States and Canada. Questions were designed to understand the initial and ongoing adaptations made by pediatric exercise testing laboratories in response to COVID-19. Results were analyzed as frequency data. There were responses from 42% (35/85) of programs, with 68% (23/34) of laboratories discontinuing all exercise testing. Of the 23 programs that discontinued testing, 15 (65%) are actively working on triage plans to reopen the exercise laboratory. Personal protective equipment use include gloves (96%; 25/26), surgical masks (88%; 23/26), N-95 masks (54%; 14/26), face shields (69%; 18/26), and gowns (62%; 16/26). Approximately 47% (15/32) of programs that typically acquire metabolic measurements reported either ceasing or modifying metabolic measurements during COVID-19. Additionally, 62% (16/26) of the programs that previously obtained pulmonary function testing reported either ceasing or modifying pulmonary function testing. Almost 60% of respondents expressed a desire for additional guidance on exercise laboratory management during COVID-19.

A mathematical model for forecasting the transmission of the COVID-19 outbreak is proposed to investigate the effects of quarantined and hospitalized individuals. We analyze the proposed model by considering the existence and the positivity of the solution. Then, the basic reproduction number (R0)-the expected number of secondary cases produced by a single infection in a completely susceptible population-is computed by using the next-generation matrix to carry out the stability of disease-free equilibrium and endemic equilibrium. The results show that the disease-free equilibrium is locally asymptotically stable if R0 < 1, and the endemic equilibrium is locally asymptotically stable if R0 > 1

Altogether, 228 students and staff of the Pavlodar branch of the Semey Medical University participated in an online survey. In total, 30.3 % of respondents experienced substantial difficulties in maintaining self-isolation/social distancing. Their proportion was higher among those frequently watching, reading or listening to news about COVID-19 (41.7 % vs. 20.0 %, р < 0.001), and getting the information from online bloggers (42.9 % vs. 26.8 %, р = 0.03). The psychological stress was reported by 92.7 % of the respondents. Those who experienced the difficulties with self-isolation/social distancing were more likely to feel excessive stress due to mobility restrictions (30.4 % vs. 6.9 %, p = 0.001), limited interpersonal communication (37.7 % vs. 17.0 %, p < 0.001), distance education (26.1 % vs. 11.3 %, p = 0.006), the suspension/reduction of clinical practice (33.3 % vs. 20.1 %, p = 0.044) than the others. That group with the difficulties had a higher proportion of anxiety (26.1 % vs. 11.9 %, p = 0.008) and depression symptoms (40.6 % vs. 22.0 %, p = 0.004). Positive correlations were observed between the severity of the perceived difficulties and the frequency of watching, reading or listening to COVID-19 news (r = 0.26 p < 0.001). The difficulties correlated with symptoms of anxiety (r = 0.36, p < 0.001) and depression (r = 0.25, p < 0.001), stress due to mobility restrictions (r = 0.50, p < 0.001), limited interpersonal communication (r = 0.39, p < 0.001), and distance education (r = 0.31, p < 0.001).

In the current study, we explored changes of depression in vs. after lockdown and whether stress and loneliness during the lockdown affect subsequent depression after the COVID-19 lockdown in Austria. A repeated measures online survey was performed by Qualtrics with the first wave during the lockdown from 10th to 30th of April 2020 and the second wave after the lockdown from 11th to 22nd of June 2020. The first wave comprised 1,005 individuals (representative for age, gender, education, region) and 445 of them took part in the second wave. More individuals changed from not depressed in lockdown to depressed after lockdown (n=39, 8.8%) as compared to from depressed in lockdown to not depressed after lockdown (n=21, 4.7%). Higher stress combined with higher loneliness in lockdown had the most detrimental effect on depression after lockdown.

To better understand the genetic determinants behind the ability of ACE2 orthologs to support viral entry, we compared koala and mouse ACE2 sequences with that of human and identified the key residues in koala and mouse ACE2 that restrict viral receptor activity. Humanization of these critical residues rendered both koala and mouse ACE2 capable of binding the spike protein and facilitating viral entry. The single mutation that allowed for mouse ACE2 to serve as a viral receptor provides a potential avenue for the development of SARS-CoV-2 mouse model.

This study aimed at exploring the active components and mechanisms of Jinhua Qinggan granules (JQG) in the prevention and treatment of coronavirus disease 2019 (COVID-19) using network pharmacology and molecular docking technology. Visualization analysis demonstrated that the core active components of JQG had a strong affinity for SARS-CoV-2 3CL hydrolase, SARS-CoV-2 S protein, ACE2, and SOCS1. These data imply that the potential active components of JQG may act on multiple signaling pathways by binding to targets such as SARS-CoV-2 3CL hydrolase, S protein, ACE2, and SOCS1, thereby inhibiting virus replication and targeting cell binding, reducing host inflammation, and activating antiviral immunity to a certain extent.

Overall, the sampled population included 2106 respondents, and 39.3% were HCWs. Even though HCWs were more likely to exhibit a better understanding of SARS-CoV-2/COVID-19 related issues (aOR 2.195, 95%CI 1.809 to 2.664), they were not exempt for misunderstandings, particularly on actual incidence and lethality of COVID-19.

Coupling between COVID-19 and seasonal influenza leads to synchronization of their dynamics

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

Interactions between COVID-19 and other pathogens may change their dynamics. Specifically, this may hinder the modelling of empirical data when the symptoms of both infections are hard to distinguish. We introduce a model coupling the dynamics of COVID-19 and seasonal influenza, simulating cooperation, competition and asymmetric interactions. We find that the coupling synchronizes both infections, with a strong influence on the dynamics of influenza, reducing its time extent to a half.

32908584; Utility-Based Multicriteria Model for Screening Patients under the COVID-19 Pandemic

Roselli,  LRP,  Frej, et al

Computational and mathematical methods in medicine

Healthcare Response | Réponse des soins de santé

In this paper, a utility-based multicriteria model is proposed to support the physicians to deal with an important medical decision-the screening decision problem-given the squeeze put on resources due to the COVID-19 pandemic. Since the COVID-19 emerged, the number of patients with an acute respiratory failure has increased in the health units. This chaotic situation has led to a deficiency in health resources. Thus, this study, using the concepts of the multiattribute utility theory (MAUT), puts forward a mathematical model to aid physicians in the screening decision problem. The model is used to generate which of the three alternatives is the best one for where patients with suspected COVID-19 should be treated, namely, an intensive care unit (ICU), a hospital ward, or at home in isolation. Also, a decision information system, called SIDTriagem, is constructed and illustrated to operate the mathematical model proposed. Copyright © 2020 Lucia Reis Peixoto Roselli et al.

Public Health response| Interventions de santé publique

Based on the Theory of Planned Behavior (TPB), an explanatory structural model of social entrepreneurial intention was tested, and the impact of the COVID-19 crisis on this intention was evaluated. To do this, a quantitative investigation was conducted using a survey of Spanish university students, obtaining a total of 558 responses: 324 before the COVID-19 crisis and 234 during the crisis period (February and June 2020). The results obtained make it possible to validate the explanatory model of social entrepreneurial intention from the perspective of the TPB. In addition, it shows that social entrepreneurial intention decreases in times of deep socioeconomic crises and high uncertainty, such as that caused by COVID-19.

This data article describes raw statistics on occupational health and safety strategies influencing the reduction of coronavirus in South Africa. The purpose of this research was to investigate factors that could potentially influence the reduction of the spread of COVID-19 in a municipality setting. The following independent constructs are explored: physical wellness, psychological wellness, Intellectual wellness, intellectual wellness, emotional wellness and social wellness. In addition to the individual dependent variables, the influence of these constructs on the reduction of COVID-19 transmission and employee performance at a selected municipality was tested. Hypotheses emerged from the proposed influence of each of these constructs on reduction of COVID-19 transmission at a municipality. Smart PLS was used to measure the impact of the proposed hypotheses of the research. In order to describe data on the respondents' characteristics, SPSS and SMART PLS was used to generate the relevant statistics. The data generated for this research could potentially advise on how healthy and safety strategies could contribute to lowering the transmission of COVID-19 at a municipality.

We describe the neurosurgical experience at Emory University during the COVID-19 pandemic and the impact of COVID-19-related policies on resident experience.  We retrospectively reviewed all neurosurgical cases performed at Emory University Hospital between March 16, the day cancellation of elective cases was effective, and April 15, 2020, and the same period in the preceding 3 years. For the study period, we collected the number of cases and their distribution by subspecialty along with total hospital charges. Compared with an average of 606 cases performed during the study period over the past 3 years, only 145 neurosurgical cases were performed between March 16 and April 15, 2020, which corresponds to an 80% reduction in case volume and 66% decrease in hospital revenue in 2020.  Even at academic centers that were not hugely impacted by the COVID-19 pandemic, prophylactic and preparedness measures still exhibited an unprecedented toll on neurosurgical resident and fellow experience.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

The future trajectory of the Covid-19 pandemic hinges on the dynamics of adaptive immunity against SARS-CoV2; however, salient features of the immune response elicited by natural infection or vaccination are still uncertain. We use simple epidemiological models to explore estimates for the magnitude and timing of future Covid-19 cases given different protective efficacy and duration of the adaptive immune response to SARS-CoV-2, as well as its interaction with vaccines and nonpharmaceutical interventions. We find that variations in the immune response to primary SARS-CoV-2 infections and a potential vaccine can lead to dramatically different immune landscapes and burdens of critically severe cases, ranging from sustained epidemics to near elimination. Our findings illustrate likely complexities in future Covid-19 dynamics, and highlight the importance of immunological characterization beyond the measurement of active infections for adequately projecting the immune landscape generated by SARS-CoV-2 infections.

Transmission Clinical data| Données cliniques

In this report, we present two seriously ill neonates who were born from mothers with stablished COVID-19 pneumonia. Laboratory tests showed lymphopenia with high LDH and hypocalcemia right after the birth. They had fever for days without responding to antibiotics and despite ruling out other potential causes. Both patients had positive RTPCR for SARS-COV-2 in the second round of testing but the first assay tested was negative. Hydroxychloroquine was used to treat both patients; the first patient was treated with it over a period of 14 days before showing signs of improvement. The second patient responded to the treatment over a period of 5 days. Although based on the available evidences, vertical transmission of COVID-19 is less likely, many aspects of pathogenesis and transmission of this novel virus are still unclear.

Clinical data| Données cliniques Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

In this paper, we propose an improved hybrid classification approach for COVID-19 images by combining the strengths of CNNs (using a powerful architecture called Inception) to extract features and a swarm-based feature selection algorithm (Marine Predators Algorithm) to select the most relevant features. A combination of fractional-order and marine predators algorithm (FO-MPA) is considered an integration among a robust tool in mathematics named fractional-order calculus (FO). The proposed approach was evaluated on two public COVID-19 X-ray datasets which achieves both high performance and reduction of computational complexity. The proposed approach selected successfully 130 and 86 out of 51 K features extracted by inception from dataset 1 and dataset 2, while improving classification accuracy at the same time. The results are the best achieved on these datasets when compared to a set of recent feature selection algorithms. By achieving 98.7%, 98.2% and 99.6%, 99% of classification accuracy and F-Score for dataset 1 and dataset 2, respectively, the proposed approach outperforms several CNNs and all recent works on COVID-19 images.

This study aimed to describe the effectiveness and risk management of remote rehabilitation for coronavirus disease (COVID-19) patients. Out of a total of 43 patients, 14 were initially provided with remote rehabilitation and 29 with direct rehabilitation. Four patients were switched from direct to remote rehabilitation during the study, thus at the end of the study there were 18 in the remote rehabilitation group and 25 in the direct rehabilitation group. Patients in remote rehabilitation were significantly younger than those in direct rehabilitation. Of 12 patients who required intubation, 3 were given remote rehabilitation. One extracorporeal membrane oxygenation survivor underwent direct rehabilitation. All patients on remote rehabilitation were discharged home or to a hotel. Twelve out of 29 patients were transferred to a rehabilitation hospital due to delayed recovery of activities of daily living. No serious adverse events occurred.

This study aims to test the knowledge, attitude and practices (KAP) towards COVID-19 in Lebanon.  A cross-sectional study of Lebanese population comprising of 1861 participants was used to analyze the knowledge, attitude and practices of individuals concerning COVID-19 in relationship to multiple variables such as age, gender, marital status, living area, education level, occupation in addition to their degree of worrying about this disease. Our participants showed an overall appropriate knowledge (67.1%), positive attitude and practices that ranged from fair to very good, depending on its type, regarding COVID-19. In the absence of a vaccine, pandemics such as the current COVID-19 are best combatted by increasing public awareness leading to collective preventative practices. A key factor in this effort lies in creating a good environment that enhances people’s compliance with considerate pandemic behavioral rules in which governing bodies must be pivotal.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

This work presents a mobility indicator derived from fully anonymised and aggregated mobile positioning data. Even though the indicator does not provide information about the behaviour of individuals, it captures valuable insights into the mobility patterns of the population in the EU and it is expected to inform responses against the COVID-19 pandemic. Spatio-temporal harmonisation is carried out so that the indicator can provide mobility estimates comparable across European countries. The indicators are provided at a high spatial granularity (up to NUTS3). As an application, the indicator is used to study the impact of COVID-19 confinement measure on mobility in Europe. It is found that a large proportion of the change in mobility patterns can be explained by these measures. The paper also presents a comparative analysis between mobility and the infection reproduction number Rt over time. These findings will support policymakers in formulating the best data-driven approaches for coming out of confinement, mapping the socio-economic effects of the lockdown measures and building future scenarios in case of new outbreaks.

OBJECTIVE: To assess the discrepancy among and within low- and middle-income countries (LMICs) regarding PPE availability, use, and satisfaction. METHODS: The study population consisted of healthcare workers from LMICs who partook in the questionnaire survey from March 1, 2020, until April 15, 2020. RESULTS: In the bivariate analysis, gender (p = 0.05), HCWs (p < 0.01), and of care (p < 0.01) were associated with the public or private sector (p < 0.05). Using multivariate analysis, PPE factors were associated with the health sector (p < 0.05). The multivariate logistic regression model determined a Pearson's χ2 of 706.736 (d.f. = 726, p = -0.689) and a c-statistic of 0.592, indicating a good model. CONCLUSION: In LMICs, huge discrepancies are present in PPE provision to HCWs, especially among the public healthcare sectors. Efforts at national and international protective levels ought to be addressed to protect frontline HCWs at higher risk of contracting COVID-19.

Methylprednisolone pulse therapy: An alternative management of severe COVID-19

Sauñe,  PM,  Bryce-Alberti, et al

Respiratory Medicine Case Reports

Clinical data| Données cliniques Immunology | Immunologie

We present two cases of severe COVID-19 that were rejected by medical institutions. The management of the disease was done at home with methylprednisolone (MP) pulse therapy for three days. This resulted in a favorable evolution and resolution of most symptoms. COVID-19 infection presents as asymptomatic disease, non-severe symptomatic disease, and severe respiratory inflammatory disease. The first two forms are dependent on viral response and a “cytokine storm” is responsible for the progression into severe disease. Glucocorticoids (GC) reduce inflammation by different mechanism depending of their concentration. Pulses lead to overall apoptosis of immune cells. Studies using pulse MP as treatment for SARS-CoV-1 showed clinical improvement and decreased incidence of ARDS compared with patients who received low dose steroid treatment. Inhibition of excessive inflammation through timely administration of GC in the early stage of inflammatory cytokine storm effectively prevents the occurrence of ARDS. © 2020

Epidemiology| Épidémiologie Clinical data| Données cliniques

Since metabolic diseases are major risk factors for the present COVID-19 pandemic, we examined circulating soluble DPP-4 serum concentrations in patients suffering from severe COVID-19 infection and in healthy human subjects in a case control design. In this analysis sDPP-4 levels were significantly lower in COVID-19 patients compared to controls (242.70 ± 202.12 ng/mL versus 497.70 ± 188.13 ng/mL, p = 0.02). We also examined sDPP-4 serum concentrations in patients suffering from sepsis not due to corona-like viruses. In these subjects, sDPP-4 levels were not different compared to healthy case controls (p = 0.14), which might suggest the decrease of sDPP-4 to be specific for corona-like virus infections. Currently, most data point towards membrane bound ACE2 in contrast to DPP-4 as the major binding partner for COVID-19 internalization into host immune cells. However, the finding that the circulating soluble form of DPP-4 is reduced in hospitalized patients might suggest a regulatory role for both, ACE and DPP-4, in COVID-19 infections, especially since obesity and type 2 diabetes are major risk factor for a severe course of the disease

Immunosuppressive therapies increase the susceptibility of patients to infections. The current pandemic with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) compels clinicians to develop recommendations for successful clinical management and surveillance of immunocompromised patients at high risk for severe disease progression. With only few case studies published on SARS-CoV-2 infection in patients with rheumatic diseases, we report a 25-year-old male who developed moderate coronavirus disease 2019 (COVID-19) with fever, mild dyspnea, and no major complications despite having received high-dose prednisolone, cyclophosphamide, and rituximab for the treatment of highly active, life-threatening eosinophilic granulomatosis with polyangiitis (EGPA).

Metadata on weekly incident and near-incident reports from 2016 to June 2020 involving over 14 000 clients with mild to serious intellectual disability of 's Heeren Loo, a long-term care organisation for people with intellectual disability, were subjected to interrupted time series analysis, comparing the COVID-19 with the pre-COVID-19 period. The imposition of lockdown-measures coincided with a significant drop in incidents (total, P < .001; aggression, P = .008; unexplained absences, P = .008; and medication errors, P < .001).  The rise in incidents involving aggression, against the background of generally lowered reporting, underlines the need for pandemic control measures that are suitable for people with intellectual disability in long-term care.

Pulmonary embolism in COVID-19 pneumonia: An overlapping diagnosis or a misdiagnosis?

Secco,  E,  Pasqualetto, et al

Journal of Cardiovascular Echography

Clinical data| Données cliniques

Coronavirus pneumonia (COVID-19) is a novel infectious disease with a high mortality rate due to severe acute respiratory syndrome. A 57-year-old woman was admitted to the emergency department (ED) with fever, cough, atypical chest pain, and dyspnea. She remained in the ED for about 48 h while waiting for the result of the COVID-19 oropharyngeal swab. Once she tested positive, she was hospitalized in the pneumological department with a diagnosis of pneumonia based on a chest X-ray and biochemical tests. Although azithromycin and hydroxychloroquine were promptly administered, she had a worsening of dyspnea even with a high-flow oxygen mask. D-dimer was increased, and a computed tomography scan with pulmonary and leg angiogram was positive for bilateral pulmonary embolism, deep-venous thrombosis, and multiple consolidated opacities in the lung parenchyma. This case highlights the fact that, in a pandemic situation, there is a potentially fatal risk of overlooking an alternative diagnosis in a COVID-19 patient who is generally considered as suffering only from pneumonia. © 2020 Wolters Kluwer Medknow Publications.

OBJECTIVES: To describe clinical characteristics of fracture patients, including a closer look to hip fracture patients, and determine how epidemiological variables may have influenced on a higher vulnerability to SARS-CoV-2 infection, as the basis for the considerations needed to reintroduce elective surgery during the pandemic. DESIGN: Longitudinal prospective cohort study. SETTING: Level I Trauma Center in the East of Spain. PATIENTS/PARTICIPANTS: One hundred forty-four consecutive fracture patients 18 years or older admitted for surgery. INTERVENTION: Patients were tested for SARS-CoV-2 with either molecular and/or serological techniques and screened for presentation of COVID-19. MAIN OUTCOME MEASUREMENTS: Patients were interviewed and charts reviewed for demographic, epidemiological, clinical, and surgical characteristics. RESULTS: We interviewed all patients and tested 137 (95.7%) of them. Three positive patients for SARS-CoV-2 were identified (2.1%). One was asymptomatic and the other 2 required admission due to COVID-19-related symptoms. Mortality for the whole cohort was 13 patients (9%). Significant association was found between infection by SARS-CoV-2 and epidemiological variables including: intimate exposure to respiratory symptomatic patients (P = 0.025) and intimate exposure to SARS-CoV-2-positive patients (P = 0.013). No association was found when crowding above 50 people was tested individually (P = 0.187). When comparing the 2020 and 2019 hip fracture cohorts we found them to be similar, including 30-day mortality. A significant increase in surgical delay from 1.5 to 1.8 days was observed on the 2020 patients (P = 0.034). CONCLUSIONS: Patients may be treated safely at hospitals if strict recommendations are followed. Both cohorts of hip fracture patients had similar 30-day mortality. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

In this study, we evaluated the ACE2 inhibitory effects of 10 essential oils. Among them, geranium and lemon oils displayed significant ACE2 inhibitory effects in epithelial cells. In addition, immunoblotting and qPCR analysis also confirmed that geranium and lemon oils possess potent ACE2 inhibitory effects. Furthermore, the gas chromatography-mass spectrometry (GC–MS) analysis displayed 22 compounds in geranium oil and 9 compounds in lemon oil. Citronellol, geraniol, and neryl acetate were the major compounds of geranium oil and limonene that represented major compound of lemon oil. Next, we found that treatment with citronellol and limonene significantly downregulated ACE2 expression in epithelial cells. The results suggest that geranium and lemon essential oils and their derivative compounds are valuable natural anti-viral agents that may contribute to the prevention of the invasion of SARS-CoV-2/COVID-19 into the human body.

The goal of this study is to present a domain-specific approach to understand sentiments manifested within people around the globe regarding this situation. In order to attain this, corona-specific tweets are acquired from twitter platform. After gathering the tweets, they are labelled and a model is developed which is effective for detecting the actual sentiment behind a tweet related to COVID-19. The substantial assessments are performed in bi-class and multi-class setting over n-gram feature set along with cross-dataset evaluation of different machine learning techniques in order to develop the model. Our experiments reveal that the proposed model performs well in perceiving the perception of people about COVID-19 with a maximum accuracy of about 93%.

As RNA viruses have a high mutation rate therefore we wanted to identify whether this virus is also prone to mutations. For this reason we selected four major structural (Spike protein (S), Envelope protein (E), Membrane glycoprotein (M), Nucleocapsid phosphoprotein (N)) and ORF8 protein of 100 different SARS-CoV-2 isolates of fifteen countries from NCBI database and compared these to the reference sequence, Wuhan NC_045512.2, which was the first isolate of SARS-CoV-2 that was sequenced. By multiple sequence alignment of amino acids, we observed substitutions and deletion in S protein at 13 different sites in the isolates of five countries (China, USA, Finland, India and Australia) as compared to the reference sequence. Thus, we observed several mutations in the isolates thereafter the first sequencing of SARS-CoV-2 isolate, NC_045512.2, which suggested that this virus might be a threat to the whole world and therefore further studies are needed to characterize how these mutations in different proteins affect the functionality and pathogenesis of SARS-CoV-2.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

Recently, a forecasting model was developed to measure and predict daily Covid-19 cases in Malaysia for the coming 10 days using previously-confirmed cases. A Singular Spectrum Analysis-based forecasting model that discriminates noise in a time series trend is introduced. These results show that the parameter L= 4 (T/20) for RF-SSA model was suitable for short time series outbreak data and the appropriate number of eigentriples to obtain is important as it influences the forecasting result. Evidently, the RF-SSA has over-forecasted the cases by 0.36%. This indicates RF-SSA’s competence to predict the impending number of Covid-19 cases. Nevertheless, enhanced RF-SSA algorithm should to be developed for higher effectivity in capturing any extreme data changes.

PURPOSE: This present study aims to investigate the relationship between laboratory parameters on admission and prognosis of coronavirus disease 2019 (COVID-19) in maintenance hemodialysis patients, as well as providing a theoretical basis for clinical evaluation of prognosis and corresponding intervention measures. METHODS: Retrospective analysis was performed on the clinical data of 47 maintenance hemodialysis patients who infected with COVID-19 and admitted to our hospital. According to their clinical outcome, these patients were divided into a survival group (n = 38) and a fatality group (n = 9). Information on the general condition and laboratory parameters of the patients were collected. Laboratory parameters were compared between different groups. The area under the curve (AUC) was used to evaluate the prognosis of COVID-19 in maintenance hemodialysis patients. RESULTS: Statistically significant differences were observed in age, white blood cell count, neutrophil count, albumin, C-reactive protein (CRP), procalcitonin, and lactate dehydrogenase (LDH) on admission (P < 0.05). Receiver operating characteristic (ROC) curve analysis showed that the values of AUC of CRP, neutrophil count, LDH, white blood cell count, albumin, and procalcitonin were 0.895, 0.813, 0.758, 0.757, 0.743, and 0.728, respectively. CONCLUSIONS: Laboratory parameters including CRP, neutrophil count, LDH, white blood cell count, albumin, and procalcitonin were predictive on the prognosis of maintenance hemodialysis patients with COVID-19. Among them, CRP was the strongest single predictive laboratory indicator.

Fourteen natural curcuminoids were studied for their possibility of inhibiting SARS-CoV-2. We studied their in silico properties towards SARS-CoV-2 target proteins by homology modelling, ADME, drug-likeness, toxicity predictions, docking molecular dynamics simulations and MM-PBSA free energy estimation. Among the curcuminoids docked to the receptor binding domain of SARS-CoV-2 spike glycoprotein, the keto and enol forms of curcumin form strong hydrogen bond interactions with ACE2 binding residues Q493, T501, Y505, Y489 and Q498. Molecular dynamics simulations, free energy binding and interaction energy validated the interaction and stability of the docked keto and enol forms of curcumin.

Modelling/ prediction| Modélisation/prédiction Transmission

In this work we give a delay differential equation, the retarded logistic equation, as a mathematical model for the global transmission of COVID-19. This model accounts for asymptomatic carriers, pre-symptomatic or latent transmission as well as contact tracing and quarantine of suspected cases. We find that the equation admits varied classes of solutions including self-burnout, progression to herd immunity and multiple states in between. We use the term “partial herd immunity” to refer to these states, where the disease ends at an infection fraction which is not negligible but is significantly lower than the conventional herd immunity threshold. We believe that the spread of COVID-19 in every localized area can be explained by one of our solution classes. © 2020, Copyright held by the author(s).

This study aimed to evaluate the application of three-in-one intelligent screening in outpatient pre-inspection in Children's Hospital. We randomly enrolled 100 children pre-screened by traditional in the outpatient department of Children's Hospital Zhejiang University School of Medicine from February 6th to 16th, 2020, and another 100 children by the intelligent three-in-one mode from February 17th to 27th, 2020. For on-line registered patients, the system automatically sent the COVID-19 epidemiological pre-screening triage questionnaire one hour before the appointment, requiring parents to complete and submit online before arriving at the hospital.  The three-in-one intelligent pre-inspection mode took an average of (25.6±8.0) seconds for each child, which was significantly shorter than the traditional pre-inspection mode (74.8±36.4 seconds) (t=13.182, P0.05). The three-in-one intelligent pre-inspection model can effectively shorten the patient pre-check time, with similar triage coincidence rate to traditional model.

Clinical data| Données cliniques Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

In this research, we show how convolutional neural network (CNN) can be useful to detect COVID-19 using chest X-ray images. We leverage the CNN-based pre-trained models as feature extractors to substantiate transfer learning and add our own classifier in detecting COVID-19. In this regard, we evaluate performance of five different pre-trained models with fine-tuning the weights from some of the top layers. We also develop an ensemble model where the predictions from all chosen pre-trained models are combined to generate a single output. The models are evaluated through 5-fold cross validation using two publicly available data repositories containing healthy and infected (both COVID-19 and other pneumonia) chest X-ray images. We also leverage two different visualization techniques to observe how efficiently the models extract important features related to the detection of COVID-19 patients. The models show high degree of accuracy, precision, and sensitivity. We believe that the models will aid medical professionals with improved and faster patient screening and pave a way to further COVID-19 research.

OBJECTIVE: There is currently over 80,000 cases of COVID-19 in Arizona, and the number is rapidly increasing, leading the country in the rate of new daily cases. Exposure among first responders remains unknown. METHODS: Rates of SARS-CoV-2 IgG among first responders in Arizona were determined, and attitudes / views about the impact of COVID-19 on their work life was analyzed. RESULTS: Of 3,326 first responders, 50 (1.50%) tested positive for SARS-CoV-2 IgG. Most first responders thought antibody testing would help ease their anxieties (62.5%) and be beneficial to their work-life (60.6%). CONCLUSION: The rate of COVID-19 exposure among first responders in Arizona is low - 1.50%. COVID-19 is a concern among many of the first responders, and antibody testing was beneficial in easing their anxieties about going to work and performing work-related duties.

A total of 2188 patients with clinically suspected of COVID-19 in Southwest China were recruited from January 21 to February 29, 2020. Nasopharyngeal swabs, throat swabs and sputum specimens were collected to detect SARS-CoV-2 by using real-time reverse transcription-polymerase chain reaction (RT-PCR) and other 12 viruses via PCR fragment analysis combined with capillary electrophoresis. Only 1.1% (24/2188) patients with suspected COVID-19 were eventually confirmed to have SARS-CoV-2 infection, and the most frequently observed symptoms were fever (75.0%, 18/24) and cough (20.8%, 5/24). This study reveals the epidemiological features of common respiratory viruses and their clinical impact during the ongoing outbreak of COVID-19 in a mild epidemic area.

Correlation between premorbid IL-6 levels and COVID-19 mortality: Potential role for Vitamin D

Silberstein,  M

International immunopharmacology

Epidemiology| Épidémiologie Clinical data| Données cliniques

To identify whether IL-6 levels prior to infection might predict outcome, early data on COVID-19 mortality from Italy and the UK were compared with previously published results of mean IL-6 levels from these countries as well as from the USA. There was a highly significant correlation (r = 0.9883; p = 0.00025) between age-stratified mortality rates and IL-6 levels from previously published data on healthy individuals. To determine whether Vitamin D may be beneficial at lowering IL-6 levels in patients, a limited analysis of trials examining the relationship between these entities published since 2015 was undertaken. Eight out of 11 studies described a significant lowering effect of Vitamin D on IL-6. Given that IL-6 likely facilitates viral cell entry and replication, levels prior to infection may predict mortality. This provides a rationale for prophylactic and therapeutic measures directed at lowering IL-6, including Vitamin D prescription.

32841152; Association Between Generalized Anxiety Disorder Scores and Online Activity Among US Adults During the COVID-19 Pandemic: Cross-Sectional Analysis

Singh,  P,  Cumberland, et al

Journal of medical Internet research

Public Health response| Interventions de santé publique

BACKGROUND: Evidence from past pandemics suggests that fear, uncertainty, and loss of control during large-scale public health crises may lead to increased pandemic-related information seeking, particularly among persons predisposed to high anxiety. In such groups, a greater consumption of information pertaining to the COVID-19 pandemic may increase anxiety. OBJECTIVE: In this study, we examine the association between online activity and Generalized Anxiety Disorder 7 (GAD-7) scores in the United States. METHODS: We recruited participants for an online survey through advertisements on various platforms such as Google, Facebook, and Reddit. A total of 406 adult US participants with moderate to severe (≥10) GAD-7 scores met the inclusion criteria and completed the survey. Anxiety levels measured using the GAD-7 scale formed our primary outcome. Our key independent variables were average daily time spent online and average daily time spent online searching about COVID-19 within the past 14 days. We used as controls potential confounders of the relation between our key independent variables and GAD-7 scores, namely, sleep quality, the COVID-19 Fear Inventory scale, binge drinking, substance use, prescription drug abuse, and sociodemographic attributes. RESULTS: Linear multivariate regression analyses showed that GAD-7 scores were higher among those who spent >4 hours online (per day) searching for information about COVID-19 (coefficient 1.29, P=.002), controlling for all other covariates. The total time spent online was not statistically associated with GAD-7 scores. CONCLUSIONS: Results from this study indicate that limiting pandemic-related online information seeking may aid anxiety management in our study population. ©Parvati Singh, William G Cumberland, Dominic Ugarte, Tim-Allen Bruckner, Sean D Young.

Healthcare Response | Réponse des soins de santé

Purpose: (1) To what extent did telehealth usage increase for an outpatient orthopaedic trauma clinic at a Level 1 trauma center from the month before the COVID-19 stay-at-home order compared with the month immediately following the order? (2) What is the proportion of no-show visits before and after the implementation of telehealth?

Methods: Patients with internet access who had the ability to download the MyChart application on their mobile device and agreed to a telehealth visit were seen virtually between March 16, 2020 and April 10, 2020 (COVID-19) by three attending orthopaedic trauma surgeons at a large, urban, Level 1 trauma center.

Results: There was an increase in the percentage of office visits conducted via telehealth between the pre-COVID-19 and COVID-19 periods (0% 0 of 340] versus 37% 86 of 233]; p < 0.001), and by the third week of implementation, telehealth comprised approximately half of all clinic visits (57%; 30 of 53]). There was no difference in the no-show proportion between the two periods (13% 53 of 393] for the pre-COVID-19 period and 14% 37 of 270] for the COVID-19 period; p = 0.91).

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique Healthcare Response | Réponse des soins de santé

Background: Sweden has taken a different approach aiming to mitigate, not suppress, community transmission, by using physical distancing without lockdowns.

Methods: We used an age-stratified health-care demand extended SEIR (susceptible, exposed, infectious, recovered) compartmental model for all municipalities in Sweden, and a radiation model for describing inter-municipality mobility. The model was calibrated against data from municipalities in the Stockholm healthcare region.

Results: Our scenario with moderate to strong physical distancing describes well the observed health demand and deaths in Sweden up to the end of May 2020. In this scenario, the intensive care unit (ICU) demand reaches the pre-pandemic maximum capacity just above 500 beds. In the counterfactual scenario, the ICU demand is estimated to reach
20 times higher than the pre-pandemic ICU capacity. The different scenarios show quite different death tolls up to 1 September, ranging from 5000 to 41 000, excluding deaths potentially caused by ICU shortage. Additionally, our statistical analysis of all causes excess mortality indicates that the number of deaths attributable to COVID-19 could be increased by 40% (95% confidence interval: 0.24, 0.57).

This study aimed to examine the relationship between perceived adequacy of personal protective equipment (PPE) and workplace-based infection control procedures (ICP) and mental health symptoms among a sample of health-care workers in Canada within the context of the current COVID-19 pandemic. A total of 7,298 respondents started the survey, of which 5,988 reported information on the main exposures and outcomes. A total of 54.8% (95% CI], 53.5% to 56.1%) of the sample had GAD-2 scores of 3 and higher, and 42.3% (95% CI, 41.0% to 43.6%) of the sample had PHQ-2 scores of 3 and higher. Absolute differences of 18% (95% CI, 12% to 23%) and 17% (95% CI, 12% to 22%) were observed in the prevalence of GAD-2 scores of 3 and higher between workers whose perceived PPE needs and ICP needs were met compared to those who needs were not met. Differences of between 11% (95% CI, 6% to 17%) and 19% (95% CI, 14% to 24%) were observed in PHQ-2 scores of 3 and higher across these same PPE and ICP categories.

Public health interventions*| Interventions de santé publique

The implementation of governmental Non-Pharmaceutical Interventions (NPIs) has been the primary means of controlling the spread of the COVID-19. Using global mobility data, released by Apple and Google, and ACAPS NPI data, we investigate the proportional contribution of NPIs on i) size of the change (magnitude) of transition between pre- and post-lockdown mobility levels and ii) rate (gradient) of this transition. Using generalized linear models to find the best fit model we found similar results using Apple or Google data. NPIs found to impact the magnitude of the change in mobility were: Lockdown measures (Apple, Google Retail and Recreation (RAR) and Google Transit and Stations (TS)), declaring a state of emergency (Apple, Google RAR and Google TS), closure of businesses and public services (Google RAR) and school closures (Apple). Using cluster analysis and chi square tests we found that closure of businesses and public services, school closures and limiting public gatherings as well as border closures and international flight suspensions were closely related. The implementation of lockdown measures and limiting public gatherings had the greatest effect on the rate of mobility change.

Type 1 diabetes mellitus (T1DM) is rare in infants and toddlers and is usually associated with a relatively high mortality when complicated with diabetic ketoacidosis (DKA). In infants, the classical symptoms of DKA are atypical and therefore many infants with DKA are mistreated for infections. We report a case of DKA precipitated by COVID-19 in an 8-month-old infant with newly diagnosed diabetes mellitus. This case is reported in view of its rarity and originality. The relation between T1DM and COVID19 infection is discussed.

The objective of the study was to describe and compare the clinical presentation and radiological and hematological data of a cohort of symptomatic COVID19 positive T2DM diabetic patients (n = 59) versus another cohort of non-diabetic symptomatic COVID19 positive patients (n =244) diagnosed at the same time from January 2020 to May 2020. Prevalence of T2DM in symptomatic COVID19 positive patients was 59/303 (=19.5%). Diabetic patients had higher prevalence of hypertension, chronic kidney disease (CKD) and cardiac dysfunction coronary heart disease (CHD)], and congestive heart failure (CHF). Charlson Comorbidity score was significantly higher in the T2DM patients (2.4± 1.6) versus the non-diabetic -patients (0.28 ± 0.8; p: < 0.001). Clinically and radiologically, T2DM patients had significantly higher percentage of pneumonia, severe pneumonia and ARDS versus the non-diabetic patients. Hematologically, diabetic patients had significantly higher C-reactive protein (CRP), higher absolute neutrophilic count (ANC) and lower counts of lymphocytes and eosinophils compared to non-diabetic patients. They had significantly higher systolic and diastolic blood pressures, longer duration of hospitalization, ICU stay, mechanical ventilation and oxygen therapy. CRP was correlated significantly with the duration of stay in the ICU and the duration for oxygen supplementation (r = 0.37 and 0.42 respectively; p: <0.01). T2DM patients showed higher inflammatory response to COVID 19 with higher absolute neutrophilic count (ANC) and CRP with lower lymphocytic and eosinophilic counts.

This study examined the impact of social support and social trust on the activities and efficacy of the public’s risk response in the case of COVID-19. We conducted an online survey over eight days with 620 Korean adult participants. Data were analyzed using structural equation modelling and K-means cluster analysis. Our results showed that public support had a positive impact on response efficacy, while response efficacy had a positive impact on sanitation, distancing, and purchasing activities. In addition, social support positively moderated the impact of public and individual support on response efficacy, while response efficacy negatively moderated the impact on sanitation activities. These results suggest that governments should proactively supply tools and information for infection-prevention, and deliver messages that encourage and support infection-prevention activities among the public; governments, along with all other members of society, must engage in aggressive risk response measures; and there is a need for risk communication that further emphasizes the importance of personal sanitation activities in the face of viral risk.

We aimed to develop and test an effective and user-friendly tool to identify and track symptoms compatible with COVID-19 in hospital workers. We developed and pilot tested Hospital Epidemics Tracker (HEpiTracker), a newly designed app to track the spread of COVID-19 among hospital workers. Hospital staff in 9 hospital centers across 5 Spanish regions (Andalusia, Balearics, Catalonia, Galicia, and Madrid) were invited to download the app on their phones and to register their daily body temperature, COVID-19-compatible symptoms, and general health score, as well as any polymerase chain reaction and serological test results. A total of 477 hospital staff participated in the study between April 8 and June 2, 2020. Of note, both health-related (n=329) and non-health-related (n=148) professionals participated in the study; over two-thirds of participants (68.8%) were health workers (43.4% physicians and 25.4% nurses), while the proportion of non-health-related workers by center ranged from 40% to 85%. Most participants were female (n=323, 67.5%), with a mean age of 45.4 years (SD 10.6). Regarding smoking habits, 13.0% and 34.2% of participants were current or former smokers, respectively. The daily reporting of symptoms was highly variable across participating hospitals; although we observed a decline in adherence after an initial participation peak in some hospitals, other sites were characterized by low participation rates throughout the study period.

This letter to the editor includes retrospective data on patients who were admitted to the Intensive Care Departement at the Hospital Universitario Ramón y Cajal in Madrid (Spain), with the primary diagnosis of SARS-COV-2 between March 10th and June 19th, 2020. A total of 83 patients were enrolled. Overall mortality in the ICU was 24.1 %.  The incidence of bacterial coinfection at admission was only 8.4% and no patient was diagnosed at admission with any other virus than SARS-CoV-2. Isolated bacteria were: S. pneumoniae n=1, Legionella pneumophila n=2, Pseudomonas aeruginosa n=1, Klebsiella oxytoca n=1 and Methicilin-sensitive S. aureus n=2. These findings support stopping empirical antibiotics in the vast majority of patients when COVID-19 infection is confirmed. However, it is important to remark that mortality in the subgroup of patients with co-infection was very high, with a mortality rate of 57.1% versus 21.1% in patient without co-infection (p = 0.033).

This study examined impacts of COVID-19 on electronic cigarette (ECIG) users. Concept mapping, a mixed-methods approach, was used to identify COVID-19 impacts on adult ECIG users. ECIG users (n= 93) provided statements completing a prompt: “A specific way Coronavirus/COVID-19 has affected my vaping/e-cigarette use, my vaping/e-cigarette related purchasing, or other vaping/e-cigarette related behaviors or issues is…”. Participants generated 85 unique statements, sorted statements into groups of similar content and rated each statement on how true they were. Multidimensional scaling and hierarchical cluster analysis identified thematic clusters. Mean cluster ratings were compared between sample subgroups. Ten clusters were identified: Stocking up and Bulk Purchasing, Challenges in Obtaining ECIG Supplies, Alternative Purchasing Procedures, Increased ECIG use, Disruption of Routine and ECIG Use, Efforts to Decrease ECIG Use, Improving ECIG Skills, COVID-19 Health Concerns, Perceptions of ECIG Use and COVID-19, and COVID-19 Protection. More dependent ECIG users and dual users of ECIGs and cigarettes rated clusters higher than less dependent ECIG users and non-dual users. ECIG users may experience or perceive they face additional COVID-19 impacts, such as increased exposure, financial burdens, stress, and health risks.

SARS-CoV-2 infection: physiological and environmental gift factors at high altitude

VirusDisease

Epidemiology| Épidémiologie

The present report is an attempt to study the effect of physiological and environmental factors existing at high altitudes (HA) with spread of SARS-CoV-2 infection. Analysis of existing data revealed that HA natives do possess certain physiological advantages such as (1) improved hypoxic ventilatory response, (2) higher concentration of oxygen carrying molecules, haemoglobin, (3) increased production of Vitamin D, due to intense solar radiation, (4) lower rates of comorbidities such as lung infections, obesity etc. and (5) most importantly reduced production of angiotensin converting enzyme 2, a carrier molecule for SARS-CoV-2 virus entry into the host cell; all of which can collectively account for improved tolerance to SARS-CoV-2 infection in HA natives. In addition, environmental factors at HA such as (6) dry and chilly winds, (7) low air density and (8) intense UV radiations may further inhibit viral growth and spread into the atmosphere. High altitude natives may posses physiological and environmental advantage over low landers in terms of reduced severity of SARS-CoV-2 infection and its limited spread.

This study aims to ascertain renal cell carcinoma (RCC) patients’ perspectives on COVID-19 and understand the associated implications for treatment.  An online survey of RCC patients was conducted from March 22 to March 25, 2020, disseminated through social media and patient networking platforms.  A total of 539 patients (male:female 39%:58%) from 14 countries responded. Of them, 71% felt that their risk of COVID-19 infection was higher than the general population, and 27% contacted their physician to establish this. Among patients with localized disease (40%), most (42%) had scheduled surveillance scans within 6 wk–65% were unwilling to delay scans. Among patients with metastatic disease, 76% were receiving active therapy. While most patients preferred not to defer therapy (51%), patients receiving immune therapy regimens were less amenable to deferring therapy than those receiving targeted treatment (20% vs 47%). Many patients with RCC were inclined to adhere to existing schedules of surveillance (localized disease) and systemic treatment (metastatic disease).

The aim of this study is to provide estimates of excess mortality in Germany during the first wave of SARS-CoV-2 (week 10 to 23 in 2020). We analyzed age-specific numbers of deaths per week from 2016 to week 26 in 2020. We used weekly mean numbers of deaths of 2016-2019 to estimate expected weekly numbers for 2020. We estimated standardized mortality ratios (SMR) and 95% confidence intervals. The observed numbers of deaths were higher than expected for age groups 60-69, 80-89, and 90+. The age group 70-79 years did not show excess mortality.  The net excess number of deaths for weeks 10-23 was +8,071. The overall SMR was 1•03 (95%CI 1•03-1•04). The largest increase occurred among people aged 80-89 and 90+ (SMR=1•08 and SMR=1•09). A sensitivity analysis that accounts for demographic changes revealed an overall SMR of 0•98 (95%CI 0•98-0•99) and a deficit of 4,926 deaths for week 10-23, 2020.

Purpose: The aim of this study was to investigate potential markers of coagulopathy and the effects of thromboprophylaxis with low-molecular-weight heparin (LMWH) on thromboelastography (TEG) and anti-factor Xa in critically ill COVID-19 patients. Material and Methods: We conducted a prospective study in 31 consecutive adult intensive care unit (ICU) patients. TEG with and without heparinase and anti-factor Xa analysis were performed. Standard thromboprophylaxis was given with dalteparin (75–100 IU/kg subcutaneously). Results: Five patients (16%) had symptomatic thromboembolic events. All patients had a maximum amplitude (MA) > 65 mm and 13 (42%) had MA > 72 mm at some point during ICU stay. Anti-factor Xa activity were below the target range in 23% of the patients and above target range in 46% of patients. There was no significant correlation between dalteparin dose and anti-factor Xa activity. Conclusions: Patients with COVID-19 have hypercoagulability with high MA on TEG. The effect of LMWH on thromboembolic disease, anti-factor Xa activity and TEG was variable and could not be reliably predicted. This indicates that standard prophylactic doses of LMWH may be insufficient. Monitoring coagulation and the LMWH effect is important in patients with COVID-19 but interpreting the results in relation to risk of thromboembolic disease poses difficulties. © 2020 Elsevier Inc.

To describe the dietary characteristics of participants in the NutriNet Brasil cohort before and during the covid-19 pandemic. Participants (n = 10,116)  were selected to complete a questionnaire on their diet at two time points: the first time when entering the study, between January 26 and February 15, 2020, and the second between May 10 and 19, 2020. The questionnaire includes questions about the consumption of healthy (vegetables, fruits and legumes) and unhealthy (ultra-processed foods) eating markers. Comparisons of indicators based on the consumption of these markers before and during the pandemic are presented for the study population and according to gender, age group, macro-region of residence and schooling. Chi-square tests and t-tests were used to compare proportions and means, respectively, adopting p < 0.05 to identify significant differences. For all participants, we found a modest but statistically significant increase in the consumption of healthy eating markers and stability in the consumption of unhealthy food markers. This favorable pattern of dietary changes during the pandemic occurred in most sociodemographic strata. We observed a less favorable changing pattern, with a tendency to increasing consumption of healthy and unhealthy food markers, in the Northeast and North macro-regions and among people with less schooling, suggesting social inequalities in the response to the pandemic.

Our aim is to describe sociodemographic and transmission profile of COVID-19 cases that were transmitted before and after the introduction of the decree in the Bologna Local Health Authority. Cases were classified as transmitted before or after the decree according to the date of last contact with a COVID-19 case or, if this date was unavailable, we used the date of onset of symptoms considering the incubation period. Sociodemographic, clinical and epidemiological information was collected by using the infectious disease monitoring database, hospital discharge, deprivation index and long term care facility databases.  In the period after the publication of the decree, there were more elderly, females, strangers, retired, residents in nursing homes and deprived people than in the first period. There were also more health care personnel and less professionals/managers, sales or office workers. In both phases, family is mentioned as the first community attended although less frequently in the second group.  The profile of the new COVID-19 cases changed during the outbreak suggesting a differential effect of lockdown measures on the population.

Journal of Adolescent Health

Public Health response| Interventions de santé publique RCT

This study explored adherence to "stay-at-home" (SAH) orders by young adults with hazardous drinking, and the role of alcohol consumption with in-person contacts on adherence. Analyses included young adults with hazardous drinking (i.e., AUDIT-C score ≥3/4 for women/men; n = 50; ages 18–25) participating in a randomized trial in Pittsburgh, PA. Participants provided experience sampling reports on drinking twice per week from the week before SAH orders started on April 1, 2020 through 6 weeks during the SAH period. We examined how in-person contact with non-household friends changed over time and event-level relationships between alcohol consumption and in-person contacts. Results: The percentage of participants with any in-person contact in the week before SAH was 44% (95% confidence interval CI] 30%–59%), which decreased to 29% (95% CI 15%–43%) in the first SAH week and increased to 65% (95% CI 46%–85%) by SAH week 6. Controlling for average levels of alcohol consumption, on days when young adults drank, participants reported more in-person contacts compared to nondrinking days. Preliminary data indicate that, among young adults with hazardous drinking, adherence to public policies like SAH orders is suboptimal, declines over time, and is associated with drinking events.

This study aims to explore the psychology of COVID-19 patients during hospitalization. A phenomenological and robust sampling approach was employed. Sixteen patients admitted to the First Affiliated Hospital of Henan University of Science and Technology with COVID-19 from 20th January to 1st March 2020 were selected. Data were collected through semi-structured interviews, phone calls, or face-to-face interviews using quarantine measures. Data were analyzed using the Colaizzi method. The psychological experience of COVID-19 patients during hospitalization could be summarized into five themes. Firstly, attitudes toward the disease included fear, denial, and stigma during the early stages, which gradually developed into acceptance in the later stages. Secondly, the major source of stress included the viral nature of the disease, quarantine measures, and concerns regarding the health of family members. Thirdly, reactions of body and mind included disease stage-dependent emotional responses, excessive attention to symptoms, rumination, and changes in diet, sleep, and behavior. Fourthly, supportive factors included psychological adjustments, medical care, and family and social support. Finally, the disease resulted in psychological growth and patients viewed problems with gratitude through the cherishing of life, family, bravery, and tenacity.

Public Health response| Interventions de santé publique

In this study, we investigate the impact of COVID-19 on global air transportation at different scales, ranging from worldwide airport networks where airports are nodes and links between airports exist when direct flights exist, to international country networks where countries are contracted as nodes, and to domestic airport networks for representative countries/regions. We focus on the spatial-temporal evolutionary dynamics of COVID-19 in air transportation networks. Our study provides a comprehensive empirical analysis on the impact of the COVID-19 pandemic on aviation from a complex system perspective using network science tools.

Can questions summarize a corpus? Using question generation for characterizing COVID-19 research

Public Health response| Interventions de santé publique

This article describes a method, corpus2question, used to aggregate a large amount of data on texts related to COVID. Results show that applying corpus2question on a corpus of scientific articles related to COVID-19 yields relevant questions about the topic. The most frequent questions are "what is covid 19" and "what is the treatment for covid". Among the 1000 most frequent questions are "what is the threshold for herd immunity" and "what is the role of ace2 in viral entry". The authors demonstrate that the proposed method generated similar questions for 13 of the 27 expert-made questions from the CovidQA question answering dataset.

Physical activity changes and its risk factors among community-dwelling japanese older adults during the COVID-19 epidemic: Associations with subjective well-being and health-related quality of life

International Journal of Environmental Research and Public Health

Public Health response| Interventions de santé publique

We aimed to (1) assess how public health restrictions impact physical activity (PA), subjective well-being (SWB), and health-related quality of life (HRQoL) of community-dwelling elderly, and (2) investigate risk factors that lead to a decline in PA. Self-administered questionnaires assessed the changes in PA, SWB, HRQoL. Multivariate logistic regression analysis was performed to identify significant associated risk factors for decreased PA. Of 165 participants (valid response rate, 41.3%; mean age, 78.5 ± 8.0 years), 47.3% became less active, 23.0% became more active, and 29.7% maintained PA levels. There was a significant decrease in SWB at baseline and follow-up after COVID-19 restrictions in the less active group (p < 0.01). Higher levels of moderate or strenuous exercise/sports activity at baseline (odds ratio OR], 1.12; 95% confidence interval CI], 1.01–1.24), and lower mental component HRQoL scores at baseline (OR, 0.96; 95% CI, 0.93–0.99) were associated with an increased risk of decreased PA. Public health restrictions impact the PA of the elderly, especially those who had higher levels of exercise/sports activity and lower HRQoL before COVID-19.

The viral protein fragment theory of COVID-19 pathogenesis

Suzuki,  YJ

Medical hypotheses

Coronavirology| Coronavirologie

This article describes the hypothesis of the viral protein fragment theory of COVID-19 pathogenesis, based on observations in cultured human vascular cells that SARS-CoV-2 spike protein can activate cell signaling events without the rest of the viral components. It is generally thought that SARS-CoV-2 and other single-stranded RNA viruses attach to the host cells through the interactions between surface proteins of the viral capsid and the host cell receptors; the fusion and the entry of the viral components, resulting in the replication of the viruses; and the host cell responses are the consequence of these events.

Public Health response| Interventions de santé publique

We aimed to explore the effect of disruption to scheduled oncology services and the UK Government shielding letter on emotional and cognitive vulnerability and to investigate the relationship between COVID-19 related emotional vulnerability (COVID-EMV) and anxiety, depression and perceived cognitive function. Women diagnosed with primary breast cancer (N = 234) completed a series of online questionnaires to assess their cognitive and emotional wellbeing as well as their COVID-EMV. Results indicated that disrupted oncology services had a significant impact on COVID-EMV, anxiety and depression, with those experiencing disruptions expressing higher general emotional vulnerability as well as COVID-EMV. Further, the UK Government letter had a significant effect on perceived cognitive function; those who received the letter reported poorer cognitive function. Regression analyses revealed that after allowing for the effects of sociodemographic and clinical variables, women’s COVID-EMV significantly predicted worse outcomes of anxiety, depression and perceived cognitive function. Our findings indicate that concerns about COVID-19 amongst women affected by breast cancer leads to increased risk of developing affective disorder, such as anxiety and depression symptomatology, among this sample.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters human cells upon binding of its spike (S) glycoproteins to ACE2 receptors and causes the Coronavirus disease 2019 (COVID-19). Therapeutic approaches to prevent SARS-CoV-2 infection are mostly focused on blocking S-ACE2 binding, but critical residues that stabilize this interaction are not well understood. By performing all-atom Molecular Dynamics (MD) simulations, we identified an extended network of salt bridges, hydrophobic and electrostatic interactions, and hydrogen bonding between the receptor-binding domain (RBD) of the S protein and ACE2. Mutagenesis of these residues on the RBD was not sufficient to destabilize binding but reduced the average work to unbind the S protein from ACE2. In particular, the hydrophobic end of RBD serves as the main anchor site and unbinds last from ACE2 under force. We propose that blocking this site via neutralizing antibody or nanobody could prove an effective strategy to inhibit S-ACE2 interactions.Competing Interest StatementThe authors have declared no competing interest.

Healthcare Response | Réponse des soins de santé

The pulmonary function test (PFT) is an important test for risk stratification before allogeneic transplantation (allo-HCT). However, it might be preferable to avoid PFT as much as possible in the recent era of coronavirus disease 2019 (COVID-19), because PFT requires forced expirations and might produce aerosols, increasing the risk of COVID-19 transmission. Therefore, we tried to predict normal PFT results before allo-HCT based on computed tomography (CT) findings. This study included 390 allo-HCT recipients at our center for whom lung CT images and PFT results before allo-HCT were available. Abnormal CT findings were less likely to be observed in the normal PFT group (47.0% versus 67.4%, P = .015), with a high negative predictive value of 92.9%. In a multivariate analysis, normal CT was significantly associated with normal PFT (odds ratio, 2.47; 95% confidence interval, 1.22 to 4.97; P = .012). A model for predicting normal PFT was constructed based on the results of a multivariate analysis, and the area under the curve of the receiver operating characteristic analysis was 0.656, which gave a sensitivity of 45.5% and a specificity of 86.0%. The relatively high specificity of the model suggested that PFT can be omitted in patients with normal CT findings before allo-HCT. © 2020 American Society for Transplantation and Cellular Therapy

The authors performed an observational study at 2 locations in Honolulu and evaluated outdoor face mask use compliance in 200 people. Simultaneous observations were performed in a downtown Honolulu business area and in Waikiki, an area focusing on tourism. Overall, 77% of all subjects used face masks in an appropriate fashion, covering their nose and mouth, while 23% were either incorrectly masked or not masked. The rate of compliance with correct public mask use in downtown Honolulu (88%) was significantly higher than in Waikiki (66%) (P=.0003, Odds Ratio 95% Confidence Interval]=3.78 1.82, 7.85]) These findings suggest that there are opportunities for improvement in rates of public face mask use and a potential decrease in the spread of COVID-19 in our population.

Objective: To survey and supervise the risk of infection control and radiation safety in the radiological diagnostic workplace for COVID-19, and provide data support for the safety protection of radiographers and related staff.

Methods: 4 emergency hospitals for COVID-19 including 2 makeshift hospitals, module hospital and brick pattern hospital in Hubei province were performed for testing and evaluation of imaging performance and radiological protection for the 8 new installed CT scanners and places according to the national standards of WS 519-2019 and GBZ 130-2013. Two COVID-19 designated hospitals including general hospital and infectious disease specialized hospital were selected to carry out field investigation and sampling of environmental biological samples for 4 CT rooms. Then the samples were detected for the nucleic acid of novel coronavirus. The results of radiodiagnostic workplace overall arrangement, infection prevention and the nucleic acid testing were analyzed, and the biological safety reliability and risk point were evaluated.

Results: The indicators of imaging performance and radiation protection for 8 CT scanners in emergency hospitals could meet the requirements of national standards.Each of 2 makeshift hospitals had 3 CT rooms with the area of 38.8 m2 and 4 mm Pb equivalent thickness of protective shielding. The CT rooms in module hospital and brick pattern hospital were 20.0 m2, and 35.8 m2 in areas, with 4 mm Pb equivalent and 3 mm Pb equivalent thickness of protection shielding, respectively. The 8 radiological diagnostic workplaces of the emergency hospitals were designed and constructed based on " three zones with two passage ways". The result of the nucleic acid test indicated that the positive samples were found at the multiple sites such as scanning bed, internal of gantry and ground touched by patients in CT scanning room.

This study describes the experience with a hybrid gastroenterology electronic consultation programme starting in 2019. Electronic consultations were performed for every referral regardless of indication as well as directly initiated telephone-based telehealth visits with patients without the need for in-person clinic.  Over five consecutive months, 1243 hybrid electronic consultations were performed with 356 (29%) resulting in a clinic appointment. The remaining 887 (71%) electronic consultations were resolved without need for a clinic visit. Five hundred and fourteen (41%) electronic consultations resulted in a directly scheduled procedure without clinic appointment. Eighty-five per cent of electronic consultations were performed on the same day of referral and 98% of electronic consultations were completed in under 20 min. A hybrid electronic consultation model which pre-emptively reviews all outpatient referrals streamlines access to specialty care.

Virus host-genome similarity (HGS) is an important factor that reflects the adaptability of virus to host. SARS-CoV-2 may retain beneficial mutations to increase HGS and evade the host immune system. This study investigated the HGSs between 399 SARS-CoV-2 strains and 10 hosts of different species, including bat, mouse, cat, swine, snake, dog, pangolin, chicken, human and monkey. The results showed that the HGS between SARS-CoV-2 and bat was the highest, followed by mouse and cat. Human and monkey had the lowest HGS values. In terms of genetic similarity, mouse and monkey are halfway between bat and human. These findings suggest that animals closely related to human life, especially those with high HGS, need to be closely monitored.

Journal of Allergy and Clinical Immunology: In Practice

Public Health response| Interventions de santé publique

Objective: We sought to identify changes in pediatric asthma-related health care utilization, respiratory viral testing, and air pollution during the COVID-19 pandemic.

Methods: For the time period January 17 to May 17, 2015 to 2020, asthma-related encounters and weekly summaries of respiratory viral testing data were extracted from Children's Hospital of Philadelphia electronic health records, and pollution data for 4 criteria air pollutants were extracted from AirNow. Changes in encounter characteristics, viral testing patterns, and air pollution before and after Mar 17, 2020, the date public health interventions to limit viral transmission were enacted in Philadelphia, were assessed and compared with data from 2015 to 2019 as a historical reference.

Results: After March 17, 2020, in-person asthma encounters decreased by 87% (outpatient) and 84% (emergency + inpatient). Video telemedicine, which was not previously available, became the most highly used asthma encounter modality (61% of all visits), and telephone encounters increased by 19%. Concurrently, asthma-related systemic steroid prescriptions and frequency of rhinovirus test positivity decreased, although air pollution levels did not substantially change, compared with historical trends.

Conclusions: The COVID-19 pandemic in Philadelphia was accompanied by changes in pediatric asthma health care delivery patterns, including reduced admissions and systemic steroid prescriptions.

Healthcare Response | Réponse des soins de santé

ackground: During the pandemic of COVID-19, the overwhelm of infected patients created an exponential surge for ICU and ward beds. As a result, a major proportion of elective surgeries was postponed. However, various emergency and urgent procedures were allowed. Due to the mortality complications of hepatopancreatobiliary issues, we decided to afford urgent procedures under intensive protective arrangements. Method and results: In our ward (liver transplant), 4 ICU beds and 16 ward beds were allocated to non-COVID-19 patients. A total of 36 hepatopancreatobiliary procedures were managed for one month. All the surgeries were afforded under personal protective equipment and other intensive protective arrangements for personnel and patients. During 6 weeks following the surgery, all patients were followed up through telemedicine and no new case of COVID-19 was detected. Conclusion: In general, it appears that intensive protections could significantly reduce the number of COVID-19 incidence among patients with co-morbidities who undergo invasive procedures.

Epidemiology| Épidémiologie Surveillance

This is a summary of the epidemiological data in Australia related to COVID-19. Cumulatively to 30 August there have been 25,686 case notifications and 577 deaths. The number of new cases reported nationally this fortnight was 1,751, a 61% decrease from the previous fortnight (4,501).  On average this represented 125 cases diagnosed each day over the reporting period, a decrease from 322 cases per day over the previous reporting period. The majority of new cases 94% (1,640) were reported in Victoria, with a smaller number of cases reported from New South Wales (86), Queensland (19), Western Australia (5) and South Australia (1). The continued decrease in new cases observed this fortnight in Victoria is likely associated with the enhanced public health measures that are currently in place in Victoria. Locally acquired cases which were predominantly associated with several interconnected clusters continued to be reported in NSW. A total of 26 deaths were reported from cases diagnosed in this reporting period, all from Victoria and aged 75 years or older. Testing rates remain high across all jurisdictions, with an overall positivity rate for the reporting period of 0.27%. Victoria reported a positivity rate of 0.90% for this reporting period; in all other jurisdictions the positivity rate was 0.03% or lower.

The objectives are to demonstrate the impact of lung segmentation in COVID-19 automatic identification using CXR images and evaluate which contents of the image decisively contribute to the identification. We have performed lung segmentation using a U-Net CNN architecture, and the classification using three well-known CNN architectures: VGG, ResNet, and Inception. To estimate the impact of lung segmentation, we applied some Explainable Artificial Intelligence (XAI), such as LIME and Grad-CAM. To evaluate our approach, we built a database named RYDLS-20-v2, following our previous publication and the COVIDx database guidelines. We evaluated the impact of creating a COVID-19 CXR image database from different sources, called database bias, and the COVID-19 generalization from one database to another, representing our less biased scenario. The experimental results of the segmentation achieved a Jaccard distance of 0.034 and a Dice coefficient of 0.982. In the best and more realistic scenario, we achieved an F1-Score of 0.74 and an area under the ROC curve of 0.9 for COVID-19 identification using segmented CXR images. Further testing and XAI techniques suggest that segmented CXR images represent a much more realistic and less biased performance.

Epidemiology| Épidémiologie

OBJECTIVE: To describe variations in COVID-19 confirmed cases and deaths among assisted living (AL) residents and examine their associations with key AL characteristics.

METHODS:  Observational study employing data on confirmed COVID-19 cases and deaths in ALs from seven states, through May 29, 2020. Information on COVID-19 cases/deaths in ALs was obtained from state government websites. A national inventory of ALs was used to identify communities with and without COVID-19 cases/deaths. Medicare Beneficiary Summary File (MBSF) identifying AL residents was employed to develop AL characteristics. County-level COVID-19 lab-confirmed cases/deaths were obtained from publicly available data.

RESULTS: We found 4,865 ALs (2,647 COVID-19 cases and 777 deaths) in the 7 states. After excluding missing data the sample consisted of 3,994 ALs (82.1%) with 2,542 cases (96.0%) and 675 deaths (86.9%). State case fatality ranged from 3.32% in North Carolina to 9.26% in Connecticut, but for ALs in these states it was 12.89% and 31.59%, respectively. Among ALs with at least 1 case, mid-size communities had fewer cases (IRR=0.829; p=0.004), than very small ALs. ALs with higher proportions of racial/ethnic minorities had more COVID-19 cases (IRR=1.08; p<0.001), as did communities with higher proportions of residents with dementia, COPD and obesity.

CONCLUSION: ALs with a higher proportion of minorities had more COVID-19 cases. Many of the previously identified individual risk factors are also present in this vulnerable population.

In this study, we assessed the validity of the hypothesis that baseline electrolyte imbalances may be related to unfavourable outcomes in hospitalized COVID-19 patients.  This was a retrospective observational study, which included 408 hospitalized individuals with COVID-19 over 18 years old. Baseline levels of sodium, potassium, calcium and chloride were assessed and the effects of abnormalities in these electrolytes on requirement for intensive care unit and mechanical ventilation, hospitalization duration and treatment outcome were evaluated.  Patients were clustered based on electrolyte levels and clusters were compared according to outcome variables. Frequency of other severe disease indices was compared between the clusters. Independent factors related to COVID-19-associated deaths were also evaluated using multivariate analyses. 228 (55.8%) of the patients had at least one electrolyte imbalance at baseline. Hyponatraemia was the most frequent electrolyte abnormality. Patients with hyponatraemia, hypochloraemia or hypocalcaemia had, respectively, more frequent requirement for intensive care unit and mechanical ventilation, higher mortality rate and longer hospitalization. The clusters associated with electrolyte abnormalities had unfavourable outcomes. Hyponatraemia was an independent factor related to death from COVID-19 (OR 10.33; 95% CI 1.62–65.62; p 0.01). Furthermore, baseline electrolyte imbalances, primarily hyponatraemia, were related to poor prognosis in COVID-19 and baseline electrolyte assessment would be beneficial for evaluating the risk of severe COVID-19.

A total of 109 participants were included, and 19 participants had SARS-CoV-2-positive results. The diagnostic sensitivity of the self-collected and HCW-collected swabs was 84.2% and 89.5%, respectively. Further, results from a questionnaire answered by the participants found that loss of smell as a self-reported symptom was a strong predictor for a SARS-CoV-2-positive test.

COVID-19, caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), represents a global crisis. Key to SARS-CoV-2 therapeutic development is unraveling the mechanisms driving high infectivity, broad tissue tropism and severe pathology. Our 2.85 Å cryo-EM structure of SARS-CoV-2 spike (S) glycoprotein reveals that the receptor binding domains (RBDs) tightly bind the essential free fatty acid (FFA) linoleic acid (LA) in three composite binding pockets. The pocket also appears to be present in the highly pathogenic coronaviruses SARS-CoV and MERS-CoV. LA binding stabilizes a locked S conformation giving rise to reduced ACE2 interaction in vitro. In human cells, LA supplementation synergizes with the COVID-19 drug remdesivir, suppressing SARS-CoV-2 replication. Our structure directly links LA and S, setting the stage for intervention strategies targeting LA binding by SARS-CoV-2.

Analyzed the prognostic value of a chest radiograph severity scoring system for younger (nonelderly) patients with COVID-19. Each patient's emergency department (ED) chest radiograph was divided into six zones and examined for opacities by two cardiothoracic radiologists, and scores were collated into a total concordant lung zone severity score. Multivariable logistic regression was used to evaluate the relationship between clinical parameters, chest radiograph scores, and patient outcomes. Independent predictors of hospital admission were chest radiograph severity score of 2 or more and obesity. Among patients who were admitted, a chest radiograph score of 3 or more was an independent predictor of intubation.

Comparison of eight commercial, high-throughput, automated or ELISA assays detecting SARS-CoV-2 IgG or total antibody

Journal of Clinical Virology

Diagnostics / Pathogen detection| Diagnostics / Détection d'agents pathogènes

Compared the performance of assays detecting IgG or total antibodies to N or S antigens, validated for routine use in France, with samples from subjects with more or less severe SARS-CoV-2 infection. The positivity rate varied depending on the assay but was greater for all assays in hospitalized than non-hospitalized patients. Despite a good correlation between the assays, discrepancies occurred, without a systematic origin, even for samples taken more than 20 days after symptom onset. These discrepancies were linked to low antibody levels in pauci-symptomatic patients. Whichever assay is chosen, a false negative result may need to be ruled out with another test in a risk situation.

Describe a case of acute hepatocellular hepatitis related to COVID-19 and our experience. In our experience, liver function tests (LFTs) abnormalities are commonly seen in COVID-19 patients. From February to June 2020, 309 patients have been hospitalized for COVID-19 in our department (61% males, mean age 61). Mild or moderate LFTs alterations have been detected in 4-10% of the patients, while severe elevations were never found at the time of hospitalization. It is reasonable to assume that the hepatic alterations encountered in COVID-19 patients are multifactorial. However, the virus itself could also be responsible for a direct cytopathic effect that can eventually lead to a clinical picture of acute hepatitis, a phenomenon called viral sepsis.

Study provides first insights into Slovenian tourists’ perceived threats of covid-19 on two dimensions: severity and susceptibility. The results have shown that age affects the two measured dimensions of perceived threat and future travel avoidance, but only with women. Furthermore, people who have travelled the most in the past express the least likelihood of avoidance to travel due to the covid-19 pandemic. Those who are more educated, on the other hand, perceive higher risk, yet education has no role in their expressed future travel avoidance. The results, moreover, show that the moral obligation towards taking care of others might be a highly important element in the success factor of covid-19 measures. Finally, the results show that we cannot easily predict how the general population will behave regarding their future travel avoidance since the opinions are not polarised in the extremes.

Assessed the prognostic value of pneumonia severity score (PSS), pectoralis muscle area (PMA), and index (PMI) on chest computed tomography (CT) in adult coronavirus disease 2019 (COVID-19) patients.  The relationship between clinical variables, PSS, PMA, sex-specific PMI values, and patient outcomes (intubation, prolonged hospital stay, and death) were investigated. Patients with comorbidity had a higher mean of PSS (6.3 + 4.5 vs 3.9 + 3.8; p = 0.001). After adjusting the confounders, PSS was an independent predictor of intubation, prolonged hospital stay, and death. PMI value was a predictor of prolonged hospital stay and death. Incrementally increasing PMA value was a predictor of prolonged hospital stay and intubation. PSS, PMA, and PMI values have prognostic value in adult COVID-19 patients and can be easily assessed on chest CT images.

Assessed the knowledge, perception, and attitude of undergraduate dental students in Nigeria to the COVID-19 pandemic and infection control practices. Fifty percent of the students had adequate knowledge of COVID-19. Final-year students (58.1%) demonstrated more adequate knowledge of COVID-19 than penultimate-year students (28.6%, P = 0.008). Most (95.1%) respondents had positive attitudes towards infection control practices against COVID-19. Guidelines on COVID-19 from reputable health authorities should be reviewed by dental school authorities and disseminated to the students to suit their clinical practice.

From late 2019 to the present day, the coronavirus outbreak tragically affected the whole world and killed tens of thousands of people. Many countries have taken very stringent measures to alleviate the effects of the coronavirus disease 2019 (COVID-19) and are still being implemented. In this study, various machine learning techniques are implemented to predict possible confirmed cases and mortality numbers for the future. According to these models, we have tried to shed light on the future in terms of possible measures to be taken or updating the current measures. Support Vector Machines (SVM), Holt-Winters, Prophet, and Long-Short Term Memory (LSTM) forecasting models are applied to the novel COVID-19 dataset. According to the results, the Prophet model gives the lowest Root Mean Squared Error (RMSE) score compared to the other three models. Besides, according to this model, a projection for the future COVID-19 predictions of Turkey has been drawn and aimed to shape the current measures against the coronavirus. © 2020 Tech Science Press.

Clinical data| Données cliniques Immunology | Immunologie

Analysed the clinical characteristics, humoral immune response, sources of contamination, and outcomes among healthcare workers (HCW)s with COVID-19. Median delay between onset of symptoms and diagnosis was 4.39 days. Most frequent symptoms were cough and headache (75% respectively). Fever accounted for 68.7%. Most represented professions were nurses (42%). HCWs were mainly infected by patient contact (32.9%). 7.6% required hospitalization and 1.7% were admitted in intensive care unit. Unfortunately, one HCW died (0.5 %). Total antibodies were positive in 109/126 (86.5%). Clinical presentation of COVID-19 in HCWs does not differ from the general population. However outcomes were more favourable with a mortality rate lower than that reported in Belgian COVID-19 patients in general.

Rapid detection of inter-clade recombination in SARS-CoV-2 with Bolotie

Coronavirology| Coronavirologie

Previous methods for detecting recombination and reassortment events cannot handle the computational requirements of analyzing tens of thousands of genomes, a scenario that has now emerged in the effort to track the spread of the SARS-CoV-2 virus. Furthermore, the low divergence of near-identical genomes sequenced in short periods of time presents a statistical challenge not addressed by available methods. In this work we present Bolotie, an efficient method designed to detect recombination and reassortment events between clades of viral genomes. We applied our method to a large collection of SARS-CoV-2 genomes and discovered hundreds of isolates that are likely of a recombinant origin.

Validated the use of saliva as a biological sample for diagnosis of COVID-19. Participants presenting with signs/symptoms suggesting SARS-CoV-2 infection underwent a nasopharyngeal swab (NPS) and/or oropharyngeal swab (OPS), and saliva collection. The sensitivity and specificity of RT-PCR using saliva samples were 94.4% (95% CI 86.4–97.8) and 97.62% (95% CI 91.7–99.3), respectively. There was an overall high agreement (96.1%) between the two tests. Use of self-collected saliva samples is an easy, convenient, and low-cost alternative to conventional NP swab-based molecular tests.

Vechi,  HT,  Maia, et al

Revista do Instituto de Medicina Tropical de Sao Paulo

Clinical data| Données cliniques

In late 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged as the cause of a cluster of pneumonia cases in China, and the corresponding disease was designated as Coronavirus Disease 2019 (COVID-19), spreading quickly around the world resulting in a pandemic. COVID-19 is associated with a set of coagulation abnormalities that increase the risk of thromboembolic events, especially in patients with severe/critical disease. We describe a series of five cases of mild COVID-19, treated in an outpatient clinic, which, after an apparent clinical improvement, developed acute pulmonary embolism (APE) between the third and the fourth week after the onset of symptoms, when they are mostly related to acute illness disappearance. Thromboembolic events are also a potential complication of mild COVID-19 and can manifest later in the disease course. This finding raises discussion about the prevention of thromboembolic events in selected group of patients with mild COVID-19.

COVID-19 has to date affected over 5 million people worldwide and caused in excess of 300000 deaths. One of the principal finding is that of a thrombotic tendency within the lungs leading to high mortality. There have been increasing number of reports of peripheral arterial thrombosis as well. Most cases of arterial thrombosis is noted in patient in intensive care setting. Here-in we report a case of acute bilateral lower limb arterial thrombosis in a patient recovering at home with mild COVID-19 symptoms, highlighting that patients with milder symptoms may also suffer from prothrombotic state resulting in acute arterial occlusions. Arterial thrombosis should be suspected in these patients despite the absence of predisposing factors. © The Author(s) 2020.

The rapid spread of SARS-CoV-2 has raised a severe global public health issue, where therapy is not identified with specific drugs or vaccines. The present investigation dealt with the inhibition of various proteins and receptors of virus using phytocompounds of three pertinent medicinal plants i.e. Eurycoma harmandiana, Sophora flavescens and Andrographis paniculata. Phytocompounds known to have antiviral properties were screened against the papain-like protease (PLpro) and main protease (Mpro) / 3-chymotrypsin-like Protease (3CLpro). Molecular docking with Canthin-6-One 9-O-Beta-Glucopyranoside showed the highest binding affinity and least binding energy with both the proteases viz. PLpro and Mpro/ 3CLpro. ADMET analysis of the compound suggested that it is having drug-like properties like high gastrointestinal (gi-) absorption, no blood-brain barrier permeability, and high lipophilicity.

Are two consecutive negative RT-PCR results enough to rule out COVID-19?

New Microbes and New Infections

Clinical data| Données cliniques

The coronavirus disease 2019 (COVID-19) pandemic is redefining the world we live in, and scientists are struggling to find the best severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic tool. Routine testing is currently performed using real-time reverse transcription PCR (RT-PCR) of upper or lower respiratory tract secretions. We sought to demonstrate the importance of conducting RT-PCR using deep sampling when initial upper respiratory testing is negative in cases of high index of suspicion for COVID-19. We present the case of a 47-year-old man admitted for fever and bilateral pneumonia diagnosed via chest computed tomographic scan amidst the early peak of the COVID-19 pandemic, suggesting a SARS-CoV-2 infection. Two RT-PCR results from nasopharyngeal swab samples were negative. A bronchoscopy was then performed, and RT-PCR testing on bronchoalveolar lavage samples yielded positive results, confirming the diagnosis of COVID-19 pneumonia. RT-PCR samples of the lower respiratory tract likely contain a higher virus load and thus retain a higher sensitivity for SARS-CoV-2 detection. © 2020 The Authors

Cancer patients in SARS-CoV-2 infection: A singlecenter experience from Wuhan

Wang,  J,  Zhang, et al

Journal of Cancer

Epidemiology| Épidémiologie Clinical data| Données cliniques

Cancer is a rare comorbidity of patients with COVID-19; however, it cannot be overemphasized due to its poorer outcomes. Conducted a single-center cohort study to analyzed information of all inpatient cases with laboratory-confirmed COVID-19 who had treatment outcomes. A total of 716 patients with laboratory-confirmed COVID-19 infection were identified. Among them, a total of 12 cases (1.7%, 95% CI: 0.7%-2.6%) had history of cancer with 4 cases (33%) experiencing severe events. Compared with cases without cancer, patients with cancer have higher risks of severe events (33% vs 7.7%, p=0.012) and deaths (25% vs 3.6%, p=0.009). Found that patients older than 60 years (75%), with other comorbidities (50%), or experiencing anticancer treatment in past month (42.9%) had a numerically higher incidence of severe events.

Surveyed the current online undergraduate education status in dental medicine in mainland China during the critical stage of the COVID-19 outbreak. Ninety-seven percent of the respondents have opened online courses during COVID-19 pandemic in China, 74% of which chose live broadcast as the major teaching way. As compared with theoretical courses, fewer specialized practical curriculums were set up online with a lower satisfaction from students in most dental schools. For the general evaluation of online learning from students of different dental schools, the "online learning content" received the highest support, while the "interaction between teachers and students" showed the lowest satisfaction.

Purpose: This study aimed to determine the needs, emotions, and coping behaviors of U.S. youth during COVID-19. Methods: Two open-ended questions were posed to 1,174 MyVoice youth, aged 14–24 years, on March 20, 2020, regarding their needs and coping strategies during COVID-19. Qualitative responses were coded using thematic analysis and data were summarized with descriptive statistics. Results: The average age of the 950 respondents (RR = 80.9%) was 18.9 ± 2.8 years with 52.1% female and 63.8% white. While 32.6% of participants felt resources were readily available, 35.2% felt resources were difficult to access or unavailable. Participants also described both emotional responses (27.4%) and coping strategies (69.8%). Most emotional responses were negative, including symptoms of anxiety or depression. Commonly reported coping strategies included staying connected and maintaining positivity. Conclusions: A significant portion of U.S. youth are experiencing unmet needs and negative emotions due to COVID-19 suggesting additional youth outreach is necessary to ensure basic needs, including socialization, are met. © 2020 Society for Adolescent Health and Medicine

Healthcare Response | Réponse des soins de santé

The clinical learning environment is limited for undergraduate medical education in otolaryngology as the result of coronavirus disease 2019. In an effort to foster and rebuild the attending-medical student relationship, we have developed the R4 teaching model. This model encourages the student to read background information, respond to questions, and review online with faculty with the goal of realization of clinical decision making with gained knowledge. Within the R4 model, there are learning environment subtypes, including real patient cases, journal club, interactive quizzes, flipped classroom, and attending-lead discussions. In the absence of a multitude of "live" patients, our curricula reinstate the core of clinical teaching for medical students.

The purpose of this study was to obtain an accurate picture of the level of anxiety, depression and stress during the coronavirus outbreak (COVID-19). The results of the study showed that the number of respondents experiencing depression, anxiety, and stress in above normal (mild to severe) was 15.5%, 28.7%, and 22.2%., respectively. Thus, respondents more anxious rather than stress and depression. Overall there are significant differences between the conditions of depression, anxiety, and stress based on differences in age of the subjects.

Disparities in vulnerability to complications from COVID-19 arising from disparities in preexisting conditions in the United States

Research in Social Stratification and Mobility

Epidemiology| Épidémiologie

The COVID-19 pandemic has magnified U.S. health disparities. Though disparities in COVID-19 hospitalization by race-ethnicity are large, disparities by income and education have not been studied. Using an index based on preexisting health conditions and age, we estimate disparities in vulnerability to hospitalization from COVID-19 by income, education, and race-ethnicity for U.S. adults. The index uses estimates of health condition and age effects on hospitalization for respiratory distress prior to the pandemic validated on COVID-19 hospitalizations. We find vulnerability arising from preexisting conditions is nearly three times higher for bottom versus top income quartile adults and 60 % higher for those with a high-school degree relative to a college degree. Though non-Hispanic Blacks are more vulnerable than non-Hispanic Whites at comparable ages, among all adults the groups are equally vulnerable because non-Hispanic Blacks are younger. Hispanics are the least vulnerable. Results suggest that income and education disparities in hospitalization are likely large and should be examined directly to further understand the unequal impact of the pandemic. © 2020 Elsevier Ltd

BMJ open respiratory research

Clinical data| Données cliniques

The global pandemic of COVID-19 has challenged the management of hypoxaemic respiratory failure and strained intensive care unit resources. While prone positioning (PP) is an established therapy in mechanically ventilated patients with acute respiratory distress syndrome (ARDS), its role in conscious patients is less well defined. We retrospectively reviewed our experience of implementing early PP in a cohort of 24 patients with acute hypoxaemic respiratory failure due to COVID-19 who required support with continuous positive airway pressure (CPAP). The use of PP alongside CPAP significantly increased both the ROX index and arterial oxygen pressure:fractional inspired oxygen (PaO2:FiO2) ratio from baseline values (ROX index: 7.0±2.5 baseline vs 11.4±3.7 CPAP+PP, p<0.0001; PaO2:FiO2 ratio: 143±73 mm Hg baseline vs 252±87 mm Hg CPAP+PP, p<0.01), and the changes to both the ROX index and PaO2:FiO2 ratio remained significant 1 hour after cessation of proning. The mean duration of PP in the first 24 hours was 8±5 hours. Few complications were observed and PP was continued for a mean of 10±5 days. From our experience in a dedicated COVID-19 respiratory high care unit, PP alongside CPAP therapy was feasible, tolerated, safe and improved oxygenation. The use of conscious PP in ARDS warrants further investigation in randomised controlled trials. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use.

Sociodemographic inequality in exposure to COVID-19-induced economic hardship in the United Kingdom

Witteveen,  D

Research in Social Stratification and Mobility

Economics | Économie

The COVID-19 pandemic led to a lockdown in European countries in the first half of 2020, including stay-at-home orders and closure of non-essential businesses. To mitigate the detrimental effects on the financial stress of employees and households, the UK government implemented a furlough scheme that temporarily secured earnings up to 80 percent of regular pay. Other employees were at risk of reduced work hours or permanent job loss. Using data from the UK Household Longitudinal Study COVID-19 Supplement, this study examines the extent to which different earnings groups and sociodemographic groups (gender, race/ethnicity, class background) became exposed to economic hardship between March and May of 2020. Results indicate that lower earnings groups were more than twice as likely to experience economic hardship relative to top quintile earners. Furthermore, among pre-COVID employed individuals, men and whites had a lower probability of being furloughed or dismissed from work. Analyses indicate that these are to a large extent attributable to gender earnings inequalities within occupations and the fact that women and racial-ethnic minorities are employed in essential occupations. © 2020 Elsevier Ltd

A natural mutation between SARS-CoV-2 and SARS-CoV determines neutralization by a cross-reactive antibody

Wu,  NicholasC,  Yuan, et al

bioRxiv

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

Epitopes that are conserved among SARS-like coronaviruses are attractive targets for design of cross-reactive vaccines and therapeutics. CR3022 is a SARS-CoV neutralizing antibody to a highly conserved epitope on the receptor binding domain (RBD) on the spike protein that can cross-react with SARS-CoV-2, but with lower affinity. Using x-ray crystallography, mutagenesis, and binding experiments, we illustrate that of four amino acid differences in the CR3022 epitope between SARS-CoV-2 and SARS-CoV, a single mutation P384A fully determines the affinity difference. CR3022 does not neutralize SARS-CoV-2, but the increased affinity to SARS-CoV-2 P384A mutant now enables neutralization with a similar potency to SARS-CoV. We further investigated CR3022 interaction with the SARS-CoV spike protein by negative-stain EM and cryo-EM. Three CR3022 Fabs bind per trimer with the RBD observed in different up-conformations due to considerable flexibility of the RBD. In one of these conformations, quaternary interactions are made by CR3022 to the N-terminal domain (NTD) of an adjacent subunit. Overall, this study provides insights into antigenic variation and potential for cross-neutralizing epitopes on SARS-like viruses.Competing Interest StatementThe authors have declared no competing interest.

Impact of emission reductions and meteorology changes on atmospheric mercury concentrations during the COVID-19 lockdown

Wu,  Q,  Tang, et al

Science of the Total Environment

Public health interventions*| Interventions de santé publique

The lockdown measures to restrict the spread of Coronavirus Disease 2019 (COVID-19) and the following unfavorable meteorology in Beijing provided a natural experiment to examine how air mercury responds to strict control measures when the climate becomes humid and warm.  Existing pollution control and additional lockdown measures reduced mercury emissions by 16.7 and 12.5 kg/d during lockdown, respectively, which correspondingly reduced the concentrations of atmospheric mercury by 0.10 and 0.07 ng/m3. Emission reductions from cement clinker production contributed to the largest decrease in atmospheric mercury, implying potential mitigation effects in this sector since it is currently the number one emitter in China. Changes in meteorology raised atmospheric mercury by 0.41 ng/m3. The increases in relative humidity (9.5%) and temperature (1.2 °C) significantly offset the effect of emission reduction by 0.17 and 0.09 ng/m3, which highlights the challenge of air mercury control in humid and warm weather and the significance of understanding mercury behavior in the atmosphere and at atmospheric interfaces, especially the impact from relative humidity.

To investigate the immediate psychological effects of Coronavirus Disease 2019 (COVID-19) on medical and non-medical students.  A retrospective online survey of 805 medical students and 1900 non-medical students was conducted. Medical students estimated COVID-19 to be more serious and disastrous than non-medical students, while they scored lower than non-medical students on the Impact of Event Scale-Revised (IES-R), and less severe anxiety and depression than non-medical students. The students experienced greater impact from the outbreak and a higher rate of anxiety and depression with increased time focusing on the outbreak. The difference in psychological effects between medical and non-medical students was further enlarged when focusing time was prolonged.

We retrospectively analyzed clinical characteristics of pregnant and nonpregnant women with COVID-19 aged from 20 to 40, Wuhan, and symptoms of pregnant women with COVID-19 and compared the clinical characteristics and symptoms to historic data previously reported for H1N1. Among 64 patients, 34 (53.13%) were pregnant, with higher proportion of exposure history (29.41% vs 6.67%) and more pulmonary infiltration on computed tomography test (50% vs 10%) compared to nonpregnant women. Of pregnant patients, 27 (79.41%) completed pregnancy, 5 (14.71%) had natural delivery, 18 (52.94%) had cesarean section, and 4 (11.76%) had abortion; 5 (14.71%) patients were asymptomatic. All 23 newborns had negative reverse-transcription polymerase chain results, and an average 1-minute Apgar score was 8-9 points. Pregnant and nonpregnant patients show differences in symptoms such as fever, expectoration, and fatigue and on laboratory tests such as neurophils, fibrinogen, D-dimer, and erythrocyte sedimentation rate. Pregnant patients with COVID-19 tend to have more milder symptoms than those with H1N1.

We propose an improved method for predicting confirmed cases based on LSTM (Long-Short Term Memory) neural network. This work compares the deviation between the experimental results of the improved LSTM prediction model and the digital prediction models (such as Logistic and Hill equations) with the real data as reference. This work uses the goodness of fitting to evaluate the fitting effect of the improvement. Experiments show that the proposed approach has a smaller prediction deviation and a better fitting effect. Compared with the previous forecasting methods, the contributions of our proposed improvement methods are mainly in the following aspects: 1) we have fully considered the spatiotemporal characteristics of the data, rather than single standardized data. 2) the improved parameter settings and evaluation indicators are more accurate for fitting and forecasting. 3) we consider the impact of the epidemic stage and conduct reasonable data processing for different stage.

To investigate the neurological symptoms and implications of patients with non-critically ill COVID-19 patients. This retrospective cohort study investigated all COVID-19 patients admitted to Wuhan East-West Lake Fangcang shelter hospital. Among 1,682 patients with confirmed non-critically ill COVID-19, 509 patients (30.3%) had neurological symptoms, including myalgia (311, 18.5%), headache (216, 12.8%), fatigue (83, 4.9%), and dizziness (15, 0.9%). One hundred and fourteen patients (6.8%) were the expansion of pulmonary infection according to their chest CT images and medical history. Compared with patients without neurological symptoms, patients with neurological symptoms had a significantly longer length of hospital stay, time of nucleic acid turning negative, and the mean time from onset of symptom to hospital admission (p < 0.05). Patients with neurological symptoms were more likely to occur the expansion of pulmonary infection compared with the patients without neurological symptoms (46/509 9.0%] vs. 68/1,173 5.8%]).

In this study, we analyzed the mechanism of the Reyanning mixture and its effects against SARS-CoV-2 based on the method of network pharmacology. We used the TCM Systems Pharmacology database and employed a similarity algorithm to screen and identify the bioactive ingredients and potential targets of the Reyanning mixture. The GeneCards database was used to predict and screen the disease targets and build the active ingredient target network diagram. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to construct the target signal pathway associations. The STRING tool was used to reconstruct the protein-protein interaction network. As a result, 27 candidate targets, such as tumor necrosis factor, interferon gamma, tumor protein P53, C-reactive protein, and peroxisome proliferator-activated receptor gamma, were identified among the 33 bioactive ingredients of the 4 TCMs in the Reyanning mixture with effects on treating SARS-CoV-2. These targets were significantly enriched in 20 KEGG pathways and associated with 48 diverse GO terms. All of these targets may play a role in inhibiting inflammatory reactions, regulating immune function, and reducing lung injury to achieve the purpose of treating SARS-CoV-2.

In this retrospective study, epidemiological, clinical, laboratory, treatment and outcomes data of hospitalized patients with severe COVID-19 in Zhongnan Hospital of Wuhan University, were collected. Binary logistic regression model was use to analyse risk factors for disease progression from severe COVID-19 illness to critical illness. The effectiveness and safety of the use of methylprednisolone for patients with severe COVID-19 disease were evaluated. The results of the multivariate analysis from 175 patients with severe COVID-19 indicate that the use of methylprednisolone was a protective factor against disease progression from severe to critical illness (P<0.001; OR: 0.054 95% CI: 0.017-0.173). Among patients with severe COVID-19 aged<65 years, both the proportion of patients who progressed to critical illness (42.2% vs 90.0%, P=0.000) and the mortality(6.7% vs 30.0%, P=0.002) were lower for patients in methylprednisolone group, compared with those in the non-methylprednisolone group, whereas no statistical differences between the methylprednisolone group and the non-methylprednisolone group were found among COVID-19 patients older than 65 years. Moreover, both the levels of CD4(+) T lymphocyte counts (646 vs 463/ul, P=0.007) and IL-6(241.9 vs 82.8pg/ml, P=0.025) were higher among patients with severe COVID-19 aged<65 years, compared with those patients ≥65 years old.

Quantitative Biology

Modelling/ prediction| Modélisation/prédiction Transmission Public health interventions*| Interventions de santé publique

In this study, we designed a dynamic graph model, not for precisely predicting the number of infected cases, but for a glance of the dynamics under a public epidemic emergency situation and of different contributing factors. We demonstrated the impact of asymptomatic transmission in this outbreak and showed the effectiveness of city lockdown to halt virus spread within a city. We further illustrated that sudden emergence of a large number of cases could overwhelm the city medical system, and external medical aids are critical to not only containing the further spread of the virus but also reducing fatality.

Clinical data| Données cliniques

We report the first case of persistent COVID-19 pneumonia that was still ongoing at 2 months after onset in a patient with follicular lymphoma (FL) undergoing rituximab maintenance therapy. The patient failed to develop anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin (Ig)G and IgM antibodies, which was most probably the result of prior rituximab therapy, and thus provoked this unusual chronic state of COVID-19 pneumonia. Patients undergoing recent rituximab therapy are likely to fail to develop anti-SARS-CoV-2 antibodies, which may lead to severe and prolonged COVID-19 infections. Rituximab therapy should be avoided whenever possible during the COVID-19 pandemic.

We describe the course of the COVID-19 outbreak and the infection control measures taken for mitigation in a hemodialysis centre in Toronto, Canada. This was a retrospective cohort study including 237 maintenance hemodialysis patients and 93 hemodialysis staff at a single hemodialysis center. Due to universal screening the primary outcome was detection of SARS-CoV-2 in nasopharyngeal samples from patients and staff using reverse transcriptase–polymerase chain reaction (RT-PCR). 11 of 237 (4.6%) hemodialysis patients and 11 of 93 (12%) staff members had a positive RT-PCR test result for SARS-CoV-2. Among individuals testing positive, 12 of 22 (55%) were asymptomatic at time of testing and 7 of 22 (32%) were asymptomatic for the duration of follow-up. One patient was hospitalized at the time of SARS-CoV-2 infection and 4 additional patients with positive test results were subsequently hospitalized. 2 (18%) patients required admission to the intensive care unit. After 30 days’ follow-up, no patients had died or required mechanical ventilation. No hemodialysis staff required hospitalization. Universal droplet and contact precautions were implemented during the outbreak. Hemodialysis staff with SARS-CoV-2 infection were placed on home quarantine regardless of symptom status. Patients with SARS-CoV-2 infection, including asymptomatic individuals, were treated with droplet and contact precautions until confirmation of negative SARS-CoV-2 RT-PCR test results. Analysis of the outbreak identified 2 index cases with subsequent nosocomial transmission within the dialysis unit and in shared shuttle buses to the hemodialysis unit.

we utilized human embryonic stem cell-derived brain organoids and monolayer cortical neurons to investigate infection of brain with pseudotyped SARS-CoV-2 viral particles. Spike-containing SARS-CoV-2 pseudovirus infected neural layers within brain organoids. The expression of ACE2, a host cell receptor for SARS-CoV-2, was sustained during the development of brain organoids, especially in the somas of mature neurons, while remaining rare in neural stem cells. However, pseudotyped SARS-CoV-2 was observed in the axon of neurons, which lack ACE2. Neural infectivity of SARS-CoV-2 pseudovirus did not increase in proportion to viral load, but only 10% of neurons were infected.

Transmission Public health interventions*| Interventions de santé publique

This study aimed to describe the spread of coronavirus disease 2019 (COVID-19) from Wuhan to rural villages in the Hubei Province. COVID-19 spread from Wuhan to other cities and rural areas in Hubei, but the disease did not become widespread in rural villages because of strict prevention measures and urbanization. According to the fluctuation in the number of confirmed cases reported in Hubei after January 23, 2020, we inferred that the infected patients on the same day will become ill during the next 20 days. The advanced traffic system facilitates the direct spread of COVID-19 from Wuhan to counties, towns, and villages in the Hubei Province.There is a low possibility of COVID-19 spread from prefecture-level cities to rural areas. The findings imply that the government should limit the travelers from the cities to the rural areas, pay more attention to the prevention and control of severe acute respiratory syndrome coronavirus 2 in cities, and appropriately prolong the isolated observation period of travelers.

Epidemiology| Épidémiologie Clinical data| Données cliniques Therapeutics| Thérapeutique

Background: Vasoactive Intestinal Peptide (VIP) blocks replication of the SARS-CoV-2 virus, inhibits cytokine synthesis, prevents cytopathy, and upregulates surfactant production in human pulmonary cells. RLF-100™ (aviptadil), is currently in phase 2/3 trials with FDA Fast Track designation for treating Critical COVID-19 with Respiratory Failure. Methods: Case series of 21 consecutive with Critical COVID-19 and multiple co-morbidities, treated with intravenous aviptadil (synthetic VIP). Sixteen patients were treated with ventilation alone and five with extracorporeal membrane oxygenation (ECMO). Results: So far, 19 of 21 patients have survived. Improved radiographic appearance was seen in both lungs of 17 patients and in one lung of 2 patients. A mean 2.5-fold increase in PaO2:FiO2 ratio was seen (P<0.0001) with complete remission from respiratory failure in 9 patients and ongoing improvement in 10. Seven patients were discharged from the hospital, 7 sent to intermediate care, and 5 remain in the ICU. Four of 5 patients on ECMO have been decannulated, and thus far three have been discharged. A 75% (95% CI±3%: P<.001) reduction in IL-6 was seen with corresponding decrease in C-reactive protein. A median 3 point reduction (mean 2.7; P<0.001) in the WHO Ordinal Scale was observed (P<.001). Comment: The short term outcome in these 21 patients represent a dramatic response in patients whose comorbidities precluded their randomization in all other trials of COVID therapeutics and who were previously treated with remdesivir, tocilizumab, or convalescent plasma. Improvement in radiographic appearance, oxygenation requirement, and inflammatory markers is consistent with in vitro evidence of direct anti-viral effect

The purpose of this study was to investigate the resumption of endodontic practices in Hubei Province, China 1 month after the end of the lockdown. A total of 322 participants completed the survey. Most respondents (62%) were from Wuhan. Almost 83% of the respondents have resumed their endodontic practice partially or fully. Most respondents in practice (99%) would take measures to screen patients before treatment including paid screening measures. More than 93% of the respondents reported having taken special measures for routine endodontic treatment at this stage, with the most common measure taken being wearing an N95 mask. The rubber dam was recognized as efficient in preventing infection by most respondents. Many respondents were concerned about contracting coronavirus disease 2019 (COVID-19) as a result of routine endodontic practice at this stage, and respondents with more than 11 years of endodontic experience were significantly less concerned about infection compared with those with fewer than 5 years of experience (P <.05).

Chest X-rays are playing an important role in the testing and diagnosis of COVID-19 disease in the recent pandemic. However, due to the limited amount of labelled medical images, automated classification of these images for positive and negative cases remains the biggest challenge in their reliable use in diagnosis and disease progression. We implemented a transfer learning pipeline for classifying COVID-19 chest X-ray images from two publicly available chest X-ray datasets1,2. The classifier effectively distinguishes inflammation in lungs due to COVID-19 and Pneumonia from the ones with no infection (normal). We have used multiple pre-trained convolutional backbones as the feature extractor and achieved an overall detection accuracy of 90%, 94.3%, and 96.8% for the VGG16, ResNet50, and EfficientNetB0 backbones respectively. Additionally, we trained a generative adversarial framework (a CycleGAN) to generate and augment the minority COVID-19 class in our approach. For visual explanations and interpretation purposes, we implemented a gradient class activation mapping technique to highlight the regions of the input image that are important for predictions. Additionally, these visualizations can be used to monitor the affected lung regions during disease progression and severity stages. © 2020, The Author(s).

Science of the Total Environment

Public health interventions*| Interventions de santé publique

A top-down approach was employed to estimate the influence of lockdown measures implemented during the COVID-19 pandemic on NOx emissions and subsequent influence on surface PM2.5 and ozone in China. The nation-wide NOx emission reduction of 53.4% due to the lockdown in 2020 quarter one in China may represent the current upper limit of China's NOx emission control. During the Chinese New Year Holiday (P2), NOx emission intensity in China declined by 44.7% compared to the preceding 3 weeks (P1). NOx emission intensity increased by 20.3% during the 4 weeks after P2 (P3), despite the unchanged NO2 column. It recovered to 2019 level at the end of March (P4). The East China (22°N - 42°N, 102°E - 122°E) received greater influence from COVID-19. Overall NOx emission from East China for 2020 first quarter is 40.5% lower than 2019, and in P4 it is still 22.9% below the same period in 2019. The 40.5% decrease of NOx emission in 2020 first quarter in East China lead to 36.5% increase of surface O3 and 12.5% decrease of surface PM2.5. The elevated O3 promotes the secondary aerosol formation through heterogeneous pathways. We recommend that the complicated interaction between PM2.5 and O3 should be considered in the emission control strategy making process in the future. © 2020 Elsevier B.V.

A wide range of case fatality rate has been reported in patients with parkinson's disease. The significance of parkinson disease (PD) as a risk factor has not been well described in context of COVID-19. COVID-19 patients with PD and non-PD demonstrated different age, sex and race distribution. A conditional logistic regression found that PD patients had a significant higher risk of dying from covid-19 compared to patients without PD. The dataset lacks information on key comorbidities as well as does not include information on recovery, what does indicate the importance of preventing transmission in PD patients.

The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a major pandemic outbreak recently. Various diagnostic technologies have been under active development. The novel coronavirus disease (COVID-19) may induce pulmonary failures, and chest X-ray imaging becomes one of the major confirmed diagnostic technologies. The very limited number of publicly available samples has rendered the training of the deep neural networks unstable and inaccurate. This study proposed a two-step transfer learning pipeline and a deep residual network framework COVID19XrayNet for the COVID-19 detection problem based on chest X-ray images. COVID19XrayNet firstly tunes the transferred model on a large dataset of chest X-ray images, which is further tuned using a small dataset of annotated chest X-ray images. The final model achieved 0.9108 accuracy. The experimental data also suggested that the model may be improved with more training samples being released.

Purpose: To explore the relationship between symptomless multi-Variable apnea prediction (sMVAP) index and adverse outcomes of patients with Corona Virus Disease 2019 (COVID-19). Methods: According to the sMVAP quartiles, we divided all patients into four groups. The clinical electronic medical records, nursing records, laboratory findings, and radiological examinations for all patients with laboratory confirmed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection were reviewed. Cox proportional hazard ratio (HR) models were used to determine the risk factors associated with in hospital death. Results: A total of 97 patients were included in this study. The “Quartile 4” group 's ICU transfer rate was significantly higher than the “Quartile 1” group. Coronary heart disease, high d-dimer and sMVAP at admission were associated with increased odds of death. Conclusions: Using the sMVAP index for obstructive sleep apnea hypopnea syndrome (OSAHS) risk assessment, and then predicting the adverse outcomes of COVID-19 patients, is an effective method. Therefore, the use of sMVAP index for OSAHS screening for inpatients with COVID-19 should be vigorously promoted, and high-risk patients should be effectively managed. © 2020 Elsevier B.V.

Open Forum Infectious Diseases

Epidemiology| Épidémiologie Clinical data| Données cliniques

Background. Various types of pulmonary diseases are associated with iron deficiency. However, information on iron status in coronavirus disease 2019 (COVID-19) is scarce. Methods. This study included 50 hospitalized patients with confirmed COVID-19. The role of serum iron in predicting severity and mortality of COVID-19 was evaluated. Results. The most common symptoms of COVID-19 patients in this study were cough (82%), fever (64%), and chest distress (42%). Of the 50 patients, 45 (90%) patients had abnormally low serum iron levels (<7.8 μmol/L). The severity of COVID-19 was negatively correlated with serum iron levels before and after treatment and was positively correlated with C-reactive protein, serum amyloid A, D-dimer, lactate dehydrogenase, urea nitrogen, and myoglobin levels. Decreased serum iron level could predict the transition of COVID-19 from mild to severe and critical illness. Seven (53.8%) patients with a lower serum iron level after treatment in the critical group had died. There was a significant difference in posttreatment serum iron levels between COVID-19 survivors and nonsurvivors. Conclusions. Serum iron deficiency was detected in the patients with COVID-19. The severity and mortality of the disease was closely correlated with serum iron levels. Low serum iron concentration was an independent risk factor for death in COVID-19 patients. © The Author(s) 2020.

Public Health response| Interventions de santé publique

We analyzed compliance with social distancing and its associations with mental health. Of the 1501 respondents (52.5% female, 72.3% aged 18–59 years), 74.2%, 72.7%, and 59.7% reported avoiding going out, going to crowded places, and attending social gatherings of more than four people, respectively. Most respondents had stayed-at-home for at least four of the past seven days (58.4%; mean 4.12, Standard Deviation 2.05). Adoption, perceived effectiveness, and perceived compliance with social distancing were associated with lower stress levels and less anxiety and depressive symptoms (all p < 0.01). However, more days stayed-at-home were associated with more depressive symptoms (aOR 1.09; 95% CI 1.00, 1.18). The long-term psychological impact in relation to social distancing and staying-at-home requires further investigation.

This study aimed to examine the effects of COVID-19 on life satisfaction and perceived general health and reveal the buffering effect of perceived control on coping with COVID-19. We collected 1,847 participants' data from 31 pandemic-affected provinces in China and obtained regional epidemic data of the same provinces. We employed a moderated mediation model with both individuals' self-report data and regional epidemic data to verify the hypotheses. Our findings indicate that perceived control may act as a protective factor buffering the psychological impact of the pandemic on general health and life satisfaction. Psychological distance can serve as a mediator that explains how the COVID-19 pandemic impacts perceived general health and life satisfaction.

Decreased HD-MIR2911 absorption in human subjects with the SIDT1 polymorphism fails to inhibit SARS-CoV-2 replication

Zhou,  Z,  Zhou, et al

Cell Discovery

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

Previous studies have found that the absorption of MIR2911 in honeysuckle decoction (HD) inhibits SARS-CoV-2 replication and accelerates the negative conversion of infected patients. The SID1 transmembrane family member 1 (SIDT1) in the gastric pit cell membrane mediates the delivery of MIR2911 in HD to target cells. This study sequenced the SIDT1 gene in 135 healthy volunteers and revealed the presence of a polymorphism (rs2271496) in 16% of subjects. The results of in vitro analyses preformed by this group suggest that the amino acid replacement caused by the polymorphism compromises the capability for exogenous MIR2911 absorption in vivo, which ultimately leads to the reduction of the level of MIR2911 in blood. Subsequently, cells expressing SARS-CoV-2 or S-protein were exposed to circulating exosomes from WT and polymorphic subjects before and after consumption of HD. The results of these analyses suggested that decreased HD-MIR2911 absorption in human subjects with the SIDT1 polymorphism leads to a failure to inhibit SARS-CoV-2 replication.

32909725; Hypernatremia-A Manifestation of COVID-19: A Case Series

Zimmer,  MA,  Zink, et al

A&A practice

Clinical data| Données cliniques

We report for the first time therapy-resistant hypernatremia (plasma sodium concentration ≥150 mmol per liter) developing in 6 of 12 critically ill coronavirus disease 2019 (COVID-19) patients age 57-84 years requiring mechanical ventilation. There was no correlation between plasma sodium concentrations and sodium input. Plasma concentrations of chloride were elevated, those of potassium decreased. These findings are consistent with abnormally increased renal sodium reabsorption, possibly caused by increased angiotensin II activity secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced downregulation of angiotensin-converting enzyme 2 (ACE2) receptors. As hypernatremia was associated with increased length of intensive care unit stay, special attention should be paid to the electrolyte status of COVID-19 patients.

A model of covid-19 transmission to understand the effectiveness of the containment measures: application to data from France

Zongo,  P,  Zorom, et al

Epidemiol Infect

Modelling/ prediction| Modélisation/prédiction Public health interventions*| Interventions de santé publique

This paper used mathematical modelling to assess whether the containment measures imposed by most of the world governments are effective and sufficient to stop the epidemic of COVID-19 beyond the lock-down period. Using French data, the results of this modelling suggest that the containment methods have slowed the growth of the outbreak but are only effective with long term compliance of a very large fraction of the population. Easing of social distancing restrictions was predicted to be effective to overcome the outbreak only if transmission rates are decreased to 75% and testing volume is multiplied by three.

Cod19 and cod20: An Italian experience of active home surveillance in covid-19 patients

Zuccotti,  GV,  Bertoli, et al

International Journal of Environmental Research and Public Health

Public health interventions*| Interventions de santé publique Public Health response| Interventions de santé publique

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic found Italy unprepared to cope with the large concentrated numbers of patients infected with coronavirus disease 2019 (COVID-19) who often required hospital admission and in many cases intensive care. This pandemic very quickly overwhelmed the Italian Healthcare System. This paper describes the Active Home Surveillance System (Operations Center for Discharged Patients; COD19) and the Home Hospital Care System (COD20) and presents the clinical data collected and the level of user satisfaction with the service. The Operations Center for Discharged Patients (COD19) is an active surveillance service for home-care patients which involves: (1) monitoring critical clinical conditions; (2) recognizing social and health issues; (3) and providing necessary clinical services in the form of a telemedicine service. COD20 is a patient-specialist video consultation service that allows to perform an assessment of clinical conditions and any need to visit; defining the priority of access to specialist outpatient visits in the presence or manageable with the new video consultation model. This service was immediately necessary during the COD19 monitoring. COD19 and COD20 are based on the Amazon Web Services Serverless certified platform. The COD19 and COD20 platform can be intrinsically utilized for future epidemic outbreaks; also those with non-respiratory transmission; and is sufficiently flexible to adapt to natural catastrophes. © 2020 by the authors.

Epidemic mitigation by statistical inference from contact tracing data

 

arXiv

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

This study developed Bayesian inference methods to estimate the risk that an individual is infected. This inference is based on the list of his recent contacts and their own risk levels, as well as personal information such as results of tests or presence of syndromes. Proposed to use probabilistic risk estimation in order to optimize testing and quarantining strategies for the control of an epidemic. Results show that in some range of epidemic spreading (typically when the manual tracing of all contacts of infected people becomes practically impossible, but before the fraction of infected people reaches the scale where a lock-down becomes unavoidable), this inference of individuals at risk could be an efficient way to mitigate the epidemic. These approaches translate into fully distributed algorithms that only require communication between individuals who have recently been in contact. Such communication may be encrypted and anonymized and thus compatible with privacy preserving standards.

Assessment of Countries' Preparedness and Lockdown Effectiveness in Confronting COVID-19

 

Disaster Medicine and Public Health Preparedness

Epidemiology| Épidémiologie Public health interventions*| Interventions de santé publique

This study assessed the risks in confronting the COVID-19 pandemic and the ongoing lockdown effectiveness in Italy, Germany, Spain, France, and the USA using China's lockdown model simulation, and cases forecast until the plateau phase. Total Risk Assessment (TRA) evaluation tool was used to assess the pre-pandemic stage risks, pandemic threshold fast responsiveness, and the ongoing performance until plateau. The Infected Patient Ratio (IPR) tool was developed to measure the number of patients resulting from 1 infector during the incubation period. Both IPR and TRA were used together to forecast inflection points, plateau phases, intensive care units’ and ventilators’ breakpoints, and the Total Fatality Ratio.In Italy, Spain, France, Germany, and the USA, an inflection point is predicted within the first 15 days of April, to arrive at a plateau after another 30 to 80 days. Variations in IPR drop are expected due to variations in lockdown timing,  the extent of adherence to it, and the number of tests performed by each country.

Appendix: Process and definitions. 

 

A daily search for new publications is conducted in PubMed, Scopus, BioRxiv and MedRxiv, SSRN, Research Square, arXiv for all publications related to COVID-19 disease or SARS-CoV-2 using the search terms (COVID-19 OR SARS-CoV-2 OR "novel CoV" OR "novel coronavirus" OR nCoV) adapted to each database.  The capture is cross-referenced with publication announcements on the COVID-19 dashboards set up by a number of publishers and google.  Publishers include Lancet, Elsevier, The New England Journal of Medicine, BMJ, Wiley, Springer Nature, ChinaCDCweekly. Additionally the database is cross-referenced with other literature scans e.g. WHO publication list and activities by collaborators.  Members of the Emerging Sciences group develop 1 -2 point summaries of each publication. Please email Lisa Waddell for additional information: Lisa.Waddell@canada.ca.  References are compiled in a reworks database that has citations since the beginning of the outbreak.  All references can be accessed at this link and by the categories listed below.  The daily scan has also been compiled in an excel sheet and copies can be provided upon request or accessed here.

 

Category Definitions:

Modelling/ prediction: Predictive modeling is a process that uses data mining and probability to forecast outcomes. Each model is made up of a number of predictors, which are variables that are likely to influence future results.

Epidemiology: the branch of medicine which deals with the incidence, distribution, and possible control of diseases and other factors relating to health. Includes Ro, attack rates, case number doubling time, case fatality rate, serial interval, clinical attack rate, asymptomatic fraction, proportion of asymptomatic and infective*

Transmission: The passage of a pathogen causing communicable disease from an infected host to an uninfected host via direct or indirect routes.

Clinical data of cases: Includes clinical parameters such as incubation period, latent period, period of communicability, duration of illness, duration of hospitalization, host risk factors, as well as clinical profiles of patients; presenting symptoms, symptoms over course of illness, sequelae, comorbidities.* 

Surveillance: Public health surveillance is the continuous, systematic collection, analysis and interpretation of health-related data.  Surveillance data will likely be number of cases suspected/confirmed, number of deaths, number recovered. *

Coronavirology: All research relating to the virus; its characteristics, genetic make-up, phylogenetic analyses  

Diagnostics / Pathogen detection:  All studies on identification of the virus; culture, PCR, antibody/antigen tests etc.

Therapeutics: Studies of substances that may be used to treat infected hosts including passive immunization products.

Vaccine Research:  Studies of vaccine candidates to prevent infection with 2019-nCoV including clinical trials.

Public Health Priorities: These citations will focus on what the current research priorities are and/or where knowledge gaps exist.

Public Health interventions*: Any study evaluating how effective a public health intervention is or maybe (in the case of a predictive model).

Public Health response: These papers are typically overviews of past and current activities, they often also identify knowledge gaps and suggest future activities or objectives.

Infection Prevention and Control/ Prévention et contrôle des infections (IPAC/PCI): Any research on the effectiveness of IPC interventions should also be tagged as IPC

Health care Response: This foci would include a description of activities to deal with 2019-nCoV cases including, but not limited to:  set up of a special emergency multi-disciplinary intensive care team; Bed and medical equipment preparation/ stock piling supplies; Education and training of staff; Early case recognition and classification of disease severity.

Economics: papers discussing/ forecasting the economics of COVID-19 pandemic.

Immunology:

Animal Model:

Zoonotic: all literature discussing the transmission to and from or occurrence of naturally acquired SARS-COV-2 infection in animals. 

Review LiteratureAll articles that summarize the published literature can be tagged as a review.  This includes systematic review, meta-analysis, scoping review, overviews, umbrella reviews*

Commentary/Editorial: For commentaries, editorials, letters to the editor, other types of opinion pieces where there is no new data collected by the author or analysis conducted by the author, please tag these within the commentary category.

News articles that have not scientific information.

Annexe: Processus et définitions. 

 

Une recherche quotidienne des nouvelles publications est effectuée dans PubMed, Scopus, BioRxiv and MedRxiv, SSRN, Research Square, arXiv pour toutes les publications relatives à la maladie COVID-19 ou au SRAS-CoV-2 en utilisant les termes de recherche (COVID-19 OU SARS-CoV-2 OU « novel CoV » OU « novel coronavirus » OU nCoV).  La saisie renvoie à des annonces de publication sur les tableaux de bord du nCoV mis en place par un certain nombre d'éditeurs et par Google.  Parmi les éditeurs figurent Lancet, Elsevier, The New England Journal of Medicine, BMJ, Wiley, Springer Nature, ChinaCDCweekly.  En outre, la base de données renvoie à d'autres survols de publications, e.g. la liste des publications de l'OMS, et à des activités des collaborateurs.  Les membres du groupe scientifique émergent préparent des résumés en 1 ou 2 points de chaque publication. Pour en savoir plus, veuillez envoyer un courriel à Lisa Waddell au : Lisa.Waddell@canada.ca.  Les références sont compilées dans une base de données Refworks qui contient des citations depuis le début de l'épidémie.  Toutes les références sont accessibles à partir de ce lien et par les catégories énumérées ci-dessous. L'analyse quotidienne a également été compilée dans une feuille Excel et des copies peuvent être fournies sur demande ou consultées ici.

 

Définitions des catégories :

Modélisation / prédiction : La modélisation prédictive est un processus qui utilise l'exploration de données et la probabilité pour prévoir les résultats. Chaque modèle est composé de plusieurs prédicteurs, qui sont des variables susceptibles d'influencer les résultats futurs.

Épidémiologie : Branche de la médecine qui traite de l'incidence, de la répartition et du contrôle éventuel des maladies et d'autres facteurs liés à la santé. Comprend le taux de reproduction de base (Ro), les taux d'attaque, le temps de doublement du nombre de cas, le taux de létalité, l'intervalle sériel, le taux d'attaque clinique, la fraction asymptomatique, la proportion de cas asymptomatiques et infectieux*.

Transmission : Passage d'un agent pathogène causant une maladie transmissible d'un hôte infecté à un hôte non infecté par des voies directes ou indirectes.

Données cliniques des cas : Comprend les paramètres cliniques tels que la période d'incubation, la période de latence, la période de contagiosité, la durée de la maladie, la durée de l'hospitalisation, les facteurs de risque de l'hôte, ainsi que les profils cliniques des patients; les symptômes présentés, les symptômes au cours de la maladie, les séquelles, les comorbidités.* 

Surveillance : La surveillance de la santé publique est la collecte, l'analyse et l'interprétation continues et systématiques de données relatives à la santé.  Les données de surveillance concerneront probablement le nombre de cas suspects / confirmés, le nombre de décès, le nombre de personnes guéries. *

Coronavirologie : Toutes les recherches relatives au virus, ses caractéristiques, sa constitution génétique et les analyses phylogénétiques.  

Diagnostics / Détection d'agents pathogènes : Toutes les études sur l'identification du virus : culture, PCR, tests de dépistage d'anticorps ou d’antigènes, etc.

Thérapeutique : Étude des substances pouvant être utilisées pour traiter les hôtes infectés, y compris les produits d'immunisation passive.

Recherche sur les vaccins : Études des candidats à la vaccination pour prévenir l'infection par le 2019-nCoV, y compris des essais cliniques.

Priorités de santé publique : Ces citations porteront sur les priorités actuelles de recherche et/ou sur les lacunes dans les connaissances.

Interventions de santé publique* : Toute étude évaluant l'efficacité (réelle ou possible) d'une intervention de santé publique (dans le cas d'un modèle prédictif).

Réponse de la santé publique : Ces articles sont généralement des aperçus des activités passées et actuelles, qui identifient souvent les lacunes dans les connaissances et suggèrent des activités ou des objectifs futurs.

Prévention et contrôle des infections/Infection Prevention and Control (PCI/IPAC) : Les recherches sur l'efficacité des interventions en PCI doivent également être marquées comme PCI.
