Good afternoon,

There are 678 citations in today’s scan. 371 were considered primary research or review literature.

Highlights today include:

 

CANADA

·       Wang, X. proposes a dynamic model that incorporates individuals' behavior change in social interactions at different stages of the epidemics and fit the model to the data in Ontario, Canada, calculating the effective reproduction number Rt within each stage. Simulations demonstrate that enlarging the testing capacity and motivating infected individuals to test for an early diagnosis may facilitate mitigating the disease spread in a relatively short time. Results also indicate a significantly faster decline of confirmed positive cases if individuals practice strict physical distancing even if restricted measures are lifted.

·       Hetherington et al studied the factors associated with COVID-19 vaccine intentions among Canadian parents. 60% of parents (n=798) intended to vaccinate their children, but 9% (n=113) said they did not intend to vaccinate and 31% (n=410) were unsure. Lower education and income were inversely associated with intention to vaccinate. Incomplete vaccination history was associated with intention not to vaccinate but not uncertainty.

·       Murti et al analyzed public health declared workplace outbreaks between January 21 to June 30, 2020, and their associated cases from January 21 to July 28, to understand industry sectors impacted by workplace outbreaks in the first wave of the pandemic within Ontario, and the additional burden of illness through household transmission. There were 199 outbreaks with 1245 cases, and 68% of outbreaks and 80% of cases belonged to i) Manufacturing, ii) Agriculture, Forestry, Fishing, Hunting, iii) Transportation and Warehousing. There were 608 household cases associated with 339 (31%) outbreak cases, increasing the burden of illness by 56%.

EPIDEMIOLOGY

·       Romero-Gómez et al investigated the infectivity of clinical samples obtained from patients with SARS-CoV-2 by comparing the results obtained by RT-PCR with the growth capacity of the virus in vitro. The authors conclude that Ct values cannot be used as a unique tool to identify those patients who can be infective despite a positive SARS-CoV-2 PCR. Positive cultures were associated with low Ct values but viral growth was obtained in a sample with high Ct values.

·       Pinto et al. investigate the possible associations between physical activity levels and clinical outcomes among hospitalized patients with severe COVID-19, and find there are no association. Physical activity indexes were not associated with hospital length of stay mortality, admission to ICU, and mechanical ventilation requirement.

SEROPREVALANCE

·       Armann et al. performed a SARS-CoV-2 seroprevalence study in students and teachers in 13 secondary schools in Saxony, Germany at two timepoints in June and October 2020, respectively. The seroprevalence for SARS-CoV-2 antibodies was 0.6% in May/June and the same in September/October. Even in schools with reported Covid-19 cases before the lockdown of March 13th no clusters could be identified. These observations do not support school closures as a strategy fighting the pandemic in a low prevalence setting.

·       Ruben et al. conducted a serologic survey to estimate SARS-CoV-2 seroprevalence and assess risk factors and occupational exposures among a convenience sample of first responders in US. Seropositivity varied by occupation, with 4.8% (3/62) of firefighters; 3.6% (8/220) of police officers; and no paramedics (0/10) or administration and support staff (0/18) testing positive.

·       Vos et al use a previously established nationwide serosurveillance study  to detect SARS-CoV-2 serum antibodies in the general population of the Netherlands and identify risk factors for seropositivity amidst the first COVID-19 epidemic wave. In the midst of the first epidemic wave, 2.8% of the Dutch population was estimated to be infected with SARS-CoV-2, that is, 30 times higher than reported. This study identified independent groups with increased odds for seropositivity.

·       Thompson et al used blood donations in Scotland as a means of estimating population exposure from the first wave of the pandemic. Samples containing anti-SARS-CoV-2 neutralising antibodies were detected in blood donors who gave blood between 16 and 17 March 2020 in all Scottish health boards. Subsequently, samples containing anti-SARS-CoV-2 neutralising antibodies were detected at every further time point assayed until the end of the study.

·       Cagigi et al longitudinally assessed systemic and airway immune responses against SARS-CoV-2 in a well-characterized cohort of 147 infected. High systemic and airway antibody responses occurred in patients with moderate to severe disease, and while systemic IgG levels were maintained after acute disease, airway IgG and IgA declined significantly. In contrast, individuals with mild symptoms showed significantly lower antibody responses but their levels of antigen-specific memory B cells were comparable with those observed in patients with moderate to severe disease.

THERAPEUTICS

·       Ashraf et al. performed a RCT to investigate the efficacy of honey and nigella sativa (HNS) vs. placebo in patients with moderate or severe COVID-19 treated with standard of care. HNS treatment resulted in a significant reduction in time to symptom alleviation, time to viral clearance, hospital discharge rate and mortality rate compared to placebo.

VACCINE RESEARCH

·       Liu et al. showed that immunization of mice with a candidate subunit vaccine consisting of SARS-CoV-2 RBD and Fc fragment of human IgG, as an immunopotentiator, elicited high titer of RBD-specific antibodies with robust neutralizing activity against both pseudotyped and live SARS-CoV-2 infections.

DIAGNOSTICS

·       Al Ahmad et al proposes a novel optical method of detecting and reducing SARS-CoV-2 transmission using a light source from a smart phone and a mobile spectrophotometer to enable detection of viral proteins. The proof-of-concept is shown by detecting soluble preparations of spike protein subunits from SARS-CoV-2, followed by detection of the actual binding potential of the spike protein with its host receptor, ACE2. This technique is combined with DC bias to show that introduction of a current into the system can be used to disrupt the antigen-antibody reaction, therefore reducing virus transmission by disrupting virus-receptor interactions electrically.

MENTAL HEALTH

·       Niedzwiedz et al explored the relationship between reporting probable COVID-19 symptoms in April 2020 and psychological distress one, two and three months later. Elevated levels of psychological distress were found up to three months after probable COVID-19, compared to participants with no likely infection.

Do Zinc Supplements Enhance the Clinical Efficacy of Hydroxychloroquine?: a Randomized, Multicenter Trial

Abd-Elsalam,  S,  Soliman, et al

Biol Trace Elem Res

Clinical data| Données cliniques Therapeutics| Thérapeutique RCT

We aimed to evaluate the effect of combining chloroquine/hydroxychloroquine (CQ/HCQ) and zinc in the treatment of COVID-19 patients. This was a randomized clinical trial conducted at three major University hospitals in Egypt. Clinical recovery after 28 days was achieved by 79.2% in the zinc group and 77.9% in zinc-free treatment group, without any significant difference (p = 0.969). The need for mechanical ventilation and the overall mortality rates did not show any significant difference between the 2 groups either (p = 0.537 and 0.986, respectively). The age of the patient and the need for mechanical ventilation were the only risk factors associated with the patients' mortality by the univariate regression analysis (p = 0.001 and < 0.001, respectively). Zinc supplements did not enhance the clinical efficacy of HCQ.

Abdulrahman,  Abdulkarim,  AlSayed, et al

medRxiv

Clinical data| Données cliniques Therapeutics| Thérapeutique

We aim to assess the efficacy and safety of using Hydroxychloroquine in treatment of COVID-19 patients who are admitted in acute care hospitals in Bahrain. A random sample of 1571 patients were included, 440 of which received HCQ (treatment group) and 1131 did not receive it (control group). Our results showed that HCQ did not have a significant effect on primary outcomes due to COVID-19 infection when compared to controls after adjusting for confounders (OR 1.43 95% CI 0.85 to 2.37, P value=0.17). Co-administration of azithromycin had no effect on primary outcomes (OR 2.7 95% CI 0.82 to 8.85 P value =0.10). HCQ was found to be associated with increased risk of hypoglycemia (OR 10.9 95% CI 1.72 - 69.49, P value =0.011) and diarrhea(OR 2.8, 95% CI 1.4-5.5, P value =0.003), but not QT prolongation(OR=1.92, 95% CI 0.95-3.9, P value =0.06) or cardiac arrhythmia.(OR=1.06, 95% CI 0.55-2.05, P value =0.85).

New modeling approaches based on varimax rotation of functional principal components

Acal,  C,  Aguilera, et al

Mathematics

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

In this paper, two new functional Varimax rotation approaches are introduced. They are based on the equivalence between FPCA of basis expansion of the sample curves and Principal Component Analysis (PCA) of a transformation of the matrix of basis coefficients. A simulation study and an application with data from the curves of infections by COVID-19 pandemic in Spain are developed to study the performance of these methods by comparing the results with other existing approaches.

Pregnancy Outcomes Among Women With and Without Severe Acute Respiratory Syndrome Coronavirus 2 Infection

Adhikari,  EH,  Moreno, et al

JAMA network open

Epidemiology| Épidémiologie Clinical data| Données cliniques

To evaluate adverse outcomes associated with SARS-CoV-2 infection in pregnancy and to describe clinical management, disease progression, hospital admission, placental abnormalities, and neonatal outcomes. 3374 pregnant women (mean SD] age, 27.6 6] years) tested for SARS-CoV-2 were delivered, including 252 who tested positive.  The cohort included 2520 Hispanic (75%), 619 Black (18%), and 125 White (4%) women. There were no differences in age, parity, body mass index, or diabetes among women with or without SARS-CoV-2. SARS-CoV-2 positivity was more common among Hispanic women (230 91%] positive vs 2290 73%] negative; difference, 17.9%; 95% CI, 12.3%-23.5%; P < .001). There was no difference in the composite primary outcome (52 women 21%] vs 684 women 23%]; relative risk, 0.94; 95% CI, 0.73-1.21; P = .64). Early neonatal SARS-CoV-2 infection occurred in 6 of 188 tested infants (3%), primarily born to asymptomatic or mildly symptomatic women. There were no placental pathologic differences by illness severity. Maternal illness at initial presentation was asymptomatic or mild in 239 women (95%), and 6 of those women (3%) developed severe or critical illness. Fourteen women (6%) were hospitalized for the indication of COVID-19.

SARS-CoV-2 and ECMO: early results and experience

Akhtar,  W,  Olusanya, et al

Indian Journal of Thoracic and Cardiovascular Surgery

Clinical data| Données cliniques Healthcare Response | Réponse des soins de santé

We describe our experience and early outcomes with critically unwell SARS-CoV-2 patients who required extracorporeal membrane oxygenation (ECMO). A retrospective cohort study including 18 SARS-CoV-2 patients who required extracorporeal support at St Bartholomew’s Hospital between 1 March 2020 and 31 July 2020. 14 survived (78%) with 4 deaths (22%). The mean duration from hospital admission to intubation was 4.1 ± 3.4 days, mean time from intubation to ECMO 2.3 ± 2 days and mean run on ECMO 17.7 ± 9.4 days. Survivor mean days from intubation to extubation was 20.6 ± 9.9 days and survivor mean days from intubation to tracheostomy decannulation 46.6 ± 15.3 days. Time from hospital admission to discharge in survivors was a mean of 57.2 ± 25.8 days.

Development of an Optical Assay to Detect SARS-CoV-2 Spike Protein Binding Interactions with ACE2 and Disruption of these Interactions Using Electric Current

Al Ahmad,  Mahmoud,  Mustafa, et al

medRxiv

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

This study proposes a novel optical method of detecting and reducing SARS-CoV-2 transmission.  The technique being proposed uses a light source from a smart phone and a mobile spectrophotometer to enable detection of viral proteins in solution or paper as well as protein-protein interactions. The proof-of-concept is shown by detecting soluble preparations of spike protein subunits from SARS-CoV-2, followed by detection of the actual binding potential of the spike protein with its host receptor, the angiotensin-converting enzyme 2 (ACE2). This technique is combined with DC bias to show that introduction of a current into the system can be used to disrupt the antigen-antibody reaction, suggesting that the proposed extended technique can be a potential means of not only detecting the virus, but also reducing virus transmission by disrupting virus-receptor interactions electrically.

The pattern and trend of covid-19 spread in the eastern mediterranean region: Curve-fitting models estimation

Al Nsour,  MAA,  Khader, et al

Pan African Medical Journal

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

This study aimed to use the Curve Estimation Procedure to assess the pattern and trend of COVID-19 spread in the countries of the Eastern Mediterranean Region (EMR) by finding the model best fit for the observed COVID-19 data in each country between 20 February 2020-21 April 2020. During this observed period, the total number of confirmed cases, recovered cases, and deaths in the region were 138673, 71343, and 6291, respectively. The overall fatality rate in the region was 4.5%. The quadratic model and the cubic model follows the observed data points fairly well during the observed time period in five and nine countries, respectively.

Optimal control problem on COVID-19 disease transmission model considering medical mask, disinfectants and media campaign

Aldila,  D

 

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de sant&amp;eacute; publique

In this paper, a system of ordinary differential equation approach is developed to understand the spread of COVID-19. We first formulate the dynamic model by dividing the human population based on their health status, awareness status, and also including the free virus on the environment. We provide a basic analysis of the model regarding the well-posed properties and how the basic reproduction number can be used to determine the final state of COVID-19 in the population. A Pontryagin Maximum's Principle used to construct the model as an optimal control problem in a purpose to determine the most effective strategies against the spread of COVID-19. Three control strategies involved in the model, such as media campaign to develop an awareness of individuals, medical masks to prevent direct transmission, and use of disinfectant to reduce the number of free virus in the environment. Through numerical simulations, we find that the time-dependent control succeeds in reducing the outbreak of COVID-19. Furthermore, if the intervention should be implemented as a single intervention, then the media campaign gives the most effective cost strategy.

CoVID-19 symptoms analysis of deceased and recovered cases using Chi-square test

Al-Najjar,  D,  Al-Najjar, et al

European review for medical and pharmacological sciences

Epidemiology| Épidémiologie Clinical data| Données cliniques

This paper aims to show the relationship between COVID-19 symptoms and patients' status including recovered and deceased cases. The study uses different CoVID-19 patients' information from different countries, the dataset contains 13174 patients with 730 as recovered and 34 cases as deceased. The Chi-square test is adopted with asymptotic significance level to show the strength of each symptom on recovered and deceased cases independently. The study found that the recovered cases are associated with different symptoms based on the patient history, where the deceased cases showed that high fever is not responsible for increasing the number of deceased cases. In addition, the use of symptoms will not give evidence of the patients' status, and therefore gender, age, reason of infection and patients' province are more dominant in determining the status of patients.

Modelling/ prediction| Modélisation/prédiction Public health interventions*| Interventions de sant&amp;eacute; publique

We modelled and simulated a test-trace-and-quarantine strategy to control the COVID-19 outbreak in the State of São Paulo, Brasil. Two alternative strategies combined with economic evaluations were simulated. One strategy included indiscriminately testing the entire population of the State, reaching more than 40 million people at a maximum cost of 2.25 billion USD, that would reduce the total number of cases by the end of 2020 by 90%. The second strategy investigated testing only symptomatic cases and their immediate contacts - this strategy reached a maximum cost of 150 million USD but also reduced the number of cases by 90%.

Assessment of burnout among primary teachers in confinement during the covid-19 period in morocco: Case of the kenitra

Amri,  A,  Abidli, et al

Pan African Medical Journal

Mental Health |

The aim is to assess the magnitude results of burnout and associated factors among primary school teachers in Kenitra in Morocco during this confinement period. This is a cross-sectional study, which was conducted during the two months of April and May 2020. Burnout was evaluated by the Maslach Burnout Inventory (MBI) with 16 items, specific to the context of Moroccan teachers and the factors of stress were assessed using a questionnaire developed by the research team. The MBI revealed that 68 teachers (54%) were victims of burnout, of which 47 (38%) had a low level; 15 (12%) had a moderate level and six (5%) had a severe burnout. Logistic regression analysis has shown that the risk factors for burnout during this confinement period are: the use and development of skills in new information and communication technologies (p<0,05); work/family conflict (p<0,05); social support (p<0,05); and the workload related to distance education (p≤0,05).

Forecasting Time Series with Multiplicative Trend Exponential Smoothing and LSTM: COVID-19 Case Study

Arceda,  MAM,  Laura, et al

 

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

In this work, we present an analysis of time series of COVID-19 confirmed cases with Multiplicative Trend Exponential Smoothing (MTES) and Long Short-Term Memory (LSTM). We evaluated the results utilizing COVID-19 confirmed cases data from countries with higher indices as the United States (US), Italy, Spain, and other countries that presumably have stopped the virus, like China, New Zealand, and Australia. Additionally, we used data from a Git repository which is daily updated, when we did the experiments we used data up to April 28th. We used 80% of data to train both models and then, we computed the Root Mean Square Error (RMSE) of test ground true data and predictions. In our experiments, MTES outperformed LSTM, we believe it is caused by a lack of historical data and the particular behavior of each country. To conclude, we performed a forecasting of new COVID-19 confirmed cases using MTES with 10 days ahead.

SARS-CoV-2 IgG antibodies in adolescent students and their teachers in Saxony, Germany (SchoolCoviDD19): persistent low seroprevalence and transmission rates between May and October 2020

Armann,  Jakob Peter,  Unrath, et al

medRxiv

Epidemiology| Épidémiologie Immunology | Immunologie

We performed a SARS-CoV-2 seroprevalence study in students and teachers at two time points in June and October 2020, respectively. Students grade 8-11 and their teachers in 13 secondary schools in eastern Saxony, Germany, were invited to participate in the SchoolCoviDD19 study. Blood samples were collected in May/June 2020 after the reopening of the schools following the March 2020 lockdown, and again in September/October 2020, 4 weeks after the end of the summer holidays. SARS-CoV-2 IgG were assed using chemiluminescence immunoassay technology. 1538 students and 507 teachers were initially enrolled, and 1334 students and 445 teachers completed both study visits. The seroprevalence for SARS-CoV-2 antibodies was 0.6% in May/June and the same in September/October. Even in schools with reported Covid-19 cases before the lockdown of March 13th no clusters could be identified. Of 12 persons with positive serology 5 had a known history of confirmed COVID-19; 23 out of 24 participants with a household history of COVID-19 were seronegative. By using a combination of three different immunoassays we could exclude 16 participants with a positive or equivocal results after initial testing. Schools do not play a crucial role in driving the SARS-CoV-2 pandemic in a low prevalence setting. Transmission in families occurs very infrequently, and the number of unreported cases is low in this age group. These observations do not support school closures as a strategy fighting the pandemic in a low prevalence setting.

Clinical data| Données cliniques Therapeutics| Thérapeutique RCT

Honey and Nigella sativa (HNS) have established antiviral properties. Hence, we investigated efficacy of HNS against COVID-19. We conducted a multicenter, placebo-controlled, randomized clinical trial at 4 centers in Pakistan. RT-PCR confirmed COVID-19 adults showing moderate or severe disease were enrolled in the study. Patients were randomly assigned in 1:1 ratio to receive either honey (1 gm/Kg/day) and Nigella sativa seeds (80 mg/Kg/day) or placebo up-to 13 days along with standard care. Three hundred and thirteen patients - 210 moderate and 103 severe - underwent randomization from April 30 to July 29, 2020. HNS resulted in 50% reduction in time taken to alleviate symptoms as compared to placebo (Moderate (4 versus 7 days), Hazard Ratio HR]: 6.11; 95% Confidence Interval CI]: 4.23-8.84, P<0.0001 and severe (6 versus 13 days)HR: 4.04; 95% CI, 2.46-6.64, P<0.0001). HNS also cleared the virus 4 days earlier than placebo group in moderate (6 versus 10 days,HR: 5.53; 95%CI: 3.76-8.14, P<0.0001) and severe cases (8.5 versus 12 days,HR: 4.32; 95%CI: 2.62-7.13, P<0.0001). HNS further led to a better clinical score on day 6 with normal activity resumption in 63.6% versus 10.9% among moderate cases (OR: 0.07; 95%CI: 0.03-0.13, P<0.0001) and hospital discharge in 50% versus 2.8% in severe cases (OR: 0.03; 95%CI: 0.01-0.09, P<0.0001). In severe cases, mortality rate was four-fold lower in HNS group than placebo (4% versus 18.87%, OR: 0.18; 95%CI: 0.02-0.92, P=0.029). No HNS-related adverse effects were observed.

How Timing of Stay-home Orders and Mobility Reductions Impacted First-Wave COVID-19 Deaths in US Counties

Audirac,  Michelle,  Tec, et al

medRxiv

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de sant&amp;eacute; publique

We offer a statistical analysis of the relative effectiveness of the timing of both official stay-at-home orders and population mobility reductions, offering a distinct (but complementary) dimension of evidence gleaned from more traditional mechanistic models of epidemic dynamics. Specifically, we use a Bayesian hierarchical model fit to county-level mortality data from the first wave of the pandemic from Jan 21 2020 through May 10 2020 to establish how timing of stay-at-home orders and population mobility changes impacted county-specific epidemic growth. We find that population mobility reductions generally preceded stay-at-home orders, and among 356 counties with a pronounced early local epidemic between January 21 and May 10 (representing 195 million people and 32,000 observed deaths), a 10 day delay in population mobility reduction would have added 16,149 (95% credible interval CI] 9,517 24,381) deaths by Apr 20, whereas shifting mobility reductions 10 days earlier would have saved 13,571 (95% CI 8,449 16,930) lives. Analogous estimates attributable to the timing of explicit stay-at-home policies were less pronounced, suggesting that mobility changes were the clearer drivers of epidemic dynamics.

This was a qualitative study deploying in-depth, individual interviews, to explore the psychosocial well-being of health and social care professionals working during the COVID-19 pandemic. This study involved 25 participants from a range of frontline professions in health and social care. From the analysis, we identified 5 overarching themes: communication challenges, work-related stressors, support structures, personal growth, and individual resilience. The participants expressed difficulties such as communication challenges and changing work conditions, but also positive factors such as increased team unity at work, and a greater reflection on what matters in life.

Angiotensin converting enzyme genotypes and mortality from COVID-19: An ecological study

Aung,  AK,  Aitken, et al

Journal of Infection

Epidemiology| Épidémiologie

We undertook an ecological study to examine the association between ACE genotypes and COVID-19 mortality across 25 countries to represent different geographical regions of the world. The population frequencies of ACE genotypes were drawn from previously published reports and data on COVID-19-related mortality were extracted from ‘Worldometer’. The frequency of II genotype is highest in east Asian countries and lower among the European and African countries. An inverse geographical distribution frequency was noted for DD genotype. Increasing II genotype frequency was significantly associated with decreased COVID-19 mortality rates (adjusted incident rate ratio IRR] 0.3, 95% confidence interval CI]: 0.002–0.7, p = 0.03). However, no association was found between DD genotype frequency and COVID-19 mortality rates (adjusted IRR 4.3, 95%CI: 0.5–41.2, p = 0.2).

COVID-19: Mitigation Measures and the Aftershock in an Overlapping Generations Model

Bairoliya,  Neha,  Imrohoroglu, et al

SSRN- Lancet prepublication

Modelling/ prediction| Modélisation/prédiction Public health interventions*| Interventions de sant&amp;eacute; publique Economics | Économie

Using an overlapping generations model, we show that a targeted lockdown policy based on preexisting health conditions would have reduced the economic severity of the pandemic by 22.5% without compromising health outcomes. Our model predicts that after the mandatory lockdown measures are lifted, individuals respond to the continued infection risk by lowering their labor supply, resulting in a slower economic recovery where output remains 2.16% below trend. The model predicts significant heterogeneity in agent’s behavioral response to the lingering infection risk. While the vulnerable wealth rich can be convinced to stay home by transfers equalling 10% of their earnings, it would require 35% of own earnings to compensate the vulnerable wealth poor. In aggregate, the vulnerable working age individuals who are at risk of infections can be convinced to self-isolate at a cost of 0.43% of GDP, once the lockdown is lifted.

In this paper a model with both epidemiological and economic content is created to balance the competing claims of saving lives and the high economic cost of shutdowns. The model indicates that an oscillating policy of strict and mild shutdowns is less effective than a policy which maintains a moderate shutdown level.

A new SARS-CoV-2 clade (GV) characterized by S substitution A222V, first reported from Spain in March, is rapidly spreading across Europe. To establish the A222V variant involvement in the infection rise in Italy, all GISAID sequences from Italy and those from our Laboratory (Lazio) in the period June-October were analysed. A222V, first recognized in August, represents 11.2% of sequences in this period, reaching 100% of autochthonous sequences in October, supporting increased GV circulation in Italy.Competing Interest StatementThe authors have declared no competing interest.Funding StatementThis study was supported by funds to the Istituto Nazionale per le Malattie Infettive (INMI) Lazzaro Spallanzani IRCCS, Rome, Italy, from the Ministero della Salute (Ricerca Corrente, linea 1; COVID-2020,12371817), the European Commission Horizon 2020 (EU project 101003544 CoNVat; EU project 101005111-DECISION; EU project 101005075-KRONO), the European Virus Archive GLOBAL (grants no. 653316 and no. 871029). and 3rd Health Programme JA: EU project 848096 SHARPAuthor DeclarationsI confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.YesThe details of the IRB/oversight body that provided approval or exemption for the research described are given below:This work was performed within the framework of the COVID-19 outbreak response and surveillance program, and has been approved by the INMI Ethical Committee (Comitato Etico INMI Lazzaro Spallanzani IRCCS/Comitato Etico Unico Nazionale Covid-19; issue n. 214/20-11-2020). https://www.inmi.it/servizio/comitato_eticoAll necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

A prospective multicentre cohort study of consecutive COVID-19 adult patients aimed to identify the factors associated with the detection of SARS-CoV-2 RNAemia at hospital admission and if its presence is associated with an unfavourable outcome. Patients with SARS-CoV-2 RNAemia required more frequently ICU admission (45.50% vs. 8.2%, P = 0.005), showed more frequently acute respiratory distress syndrome (ARDS) (54.5% vs. 9.8%, P = 0.01) and required in more cases invasive mechanical ventilation (36.4% vs. 6.6%, P = 0.018). Mortality (36.4% vs. 4.9%, P = 0.007) and unfavourable outcome (63.6% vs. 13.1%, P = 0.001), were also more frequent in patients with SARS-CoV-2 RNAemia

This study sought to determine which policies had the greatest impact on reducing the risk of in-school transmission in NYC. Adherence to infection control measures (facemasks, physical distancing, enhanced indoor ventilation, cohorting of small groups, and hand hygiene) is the highest priority for safe school re-opening. All-remote instructions, schedules that rotate in-person and remote instruction, daily symptom screening, and testing 10-20% of students and staff weekly or monthly are all less effective.

This study investigated whether anticoagulation improves survival in COVID-19 and if this improvement in survival is associated with disease severity. This cohort study simulated an intention-to-treat clinical trial, by analyzing the effect on mortality of anticoagulation therapy chosen in the first 48 hours of hospitalization.  Adjusted logistic regression analyses demonstrated a significant decrease in mortality with prophylactic use of apixaban (odds ratio OR] 0.46, p = 0.001) and enoxaparin (OR = 0.49, p = 0.001). Therapeutic apixaban was also associated with decreased mortality (OR 0.57, p = 0.006) but was not more beneficial than prophylactic use when analyzed over the entire cohort or within D-dimer stratified categories. Higher D-dimer levels were associated with increased mortality (p 10 μg/mL) derived the most benefit. There was no increase in transfusion requirement with any of the anticoagulants used.

This study examined the role of hematopoietic stem and progenitor cells (clonal hematopoiesis or CH) and whether CH predisposes to severe Covid-19 or other infections. Among 515 individuals with COVID-19, it was found that CH was associated with severe Covid-19 outcomes (OR=1.9, 95%=1.2-2.9, p=0.01). Further explored the relationship between CH and risk of other infections in 14,211 solid tumor patients. CH was significantly associated with risk of Clostridium Difficile (HR=2.0, 95%CI: 1.2-3.3, p=6×10−3) and Streptococcus/Enterococcus infections (HR=1.5, 95% CI=1.1-2.1, p=5×10−3). These findings suggest a relationship between CH and risk of severe infections that warrants further investigation.

People infected with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) display a wide range of illness, from asymptomatic infection to severe respiratory distress resulting in death. We measured serum biomarkers in uninfected individuals and in individuals with mild, moderate, or critical COVID-19 disease. Levels of monocyte activation (sCD14 and FABP4) and inflammation (TNFR1 and 2) were increased in COVID-19 individuals, regardless of disease severity. Among patients with critical disease, individuals who recovered from COVID-19 had lower levels of TNFR1 and TNFR2 at hospital admission compared to these levels in patients with critical disease that ultimately died.

This study determined the estimated time to recovery for vascular surgery procedures delayed due to COVID-19 in a regional health system. Median statewide monthly vascular surgical volume for the study period was 439 procedures, with a maximum statewide monthly case volume of 519 procedures. For the month of April 2020, elective vascular surgery procedural volume decreased by approximately 90%. Significant variability was seen in estimated hospital capacity as well as estimated backlogged cases, with the recovery of elective cases estimated to take approximately 8 months. If hospitals across the collaborative share the burden of backlogged cases, the recovery could be shortened to approximately 3 months.

The aim of the present study was to document the impact of post Covid-19 alterations to taste and smell. Participants reported difficulty understanding, explaining and managing altered taste and smell; a lack of interpersonal and professional explanation or support; altered eating; appetite loss, weight change; loss of pleasure in food, eating and social engagement; altered intimacy and an altered relationship to self and others. These findings suggest altered taste and smell with Covid-19 lead to a severe disruption to daily living that impacts on psychological well-being and health.

This study estimated the proportion of patients hospitalized with COVID-19 who undergo dialysis, tracheostomy, and extracorporeal membrane oxygenation (ECMO). 240,392 patients hospitalized with COVID-19 were included. Across the six databases, 9,703 (4.04% 95% CI: 3.96% to 4.11%]) patients received dialysis, 1,681 (0.70% 0.67% to 0.73%]) had a tracheostomy, and 398 (0.17% 95%CI: 0.15% to 0.18%]) patients underwent ECMO over the 30 days following hospitalization. Use of ECMO was generally concentrated among patients who were younger, male, and with fewer comorbidities except for obesity. Tracheostomy was used for a similar proportion of patients regardless of age, sex, or comorbidity. While dialysis was used for a similar proportion among younger and older patients, it was more frequent among male patients and among those with chronic kidney disease.

The aim of our retrospective study was to evaluate the earliest COVID19-related signal to anticipate requirements of intensive care unit (ICU) beds .  EMS calls, percentage of positive RT-PCR tests, ambulances used, ED and GP visits of COVID-19 patients were strongly associated (R2 ranging between 0.79 to 0.99, all P<0.001) with COVID-19 ICU patients with an anticipation delay of 23, 15, 14, 13, and 12 days respectively. Hospitalization did not anticipate ICU bed requirement. A qualitative analysis of the onset of the second wave period of the epidemic (August 1 to September 15, 2020) in the same region provided similar results. The daily number of COVID19-related telephone calls received by the EMS and corresponding dispatch ambulances, and the proportion of positive RT-PCR tests were the earliest indicators of the number of COVID19 patients requiring ICU care during the epidemic crisis, rapidly followed by ED and GP visits.

Airway antibodies wane rapidly after COVID-19 but B cell memory is generated across disease severity

Cagigi,  Alberto,  Yu, et al

medRxiv

Epidemiology| Épidémiologie Clinical data| Données cliniques Immunology | Immunologie

This study longitudinally assessed systemic and airway immune responses against SARS-CoV-2 in a well-characterized cohort of 147 infected individuals representing the full spectrum of COVID-19 severity; from asymptomatic infection to fatal disease. High systemic and airway antibody responses were elicited in patients with moderate to severe disease, and while systemic IgG levels were maintained after acute disease, airway IgG and IgA declined significantly. In contrast, individuals with mild symptoms showed significantly lower antibody responses but their levels of antigen-specific memory B cells were comparable with those observed in patients with moderate to severe disease. This suggests that antibodies in the airways may not be maintained at levels that prevent local virus entry upon re-exposure and therefore protection via activation of the memory B cell pool is critical.

I'm alone but not lonely. U-shaped pattern of perceived loneliness during the COVID-19 pandemic in the UK and Greece

medRxiv

Mental Health |
santé mentale

This study trained a RandomForest model using 10 variables quantifying individuals' living environment, physical and mental health statuses to predict how long each of the UK participants (N=382) had been in lockdown. Self-perceived loneliness was found to be the most important variable predicting time in lockdown and, therefore, the aspect most influenced by the time the participant spent in lockdown. Subsequent statistical analysis showed a significant U-shaped curve for the levels of perceived loneliness (p<0.012), specifically decreasing during the 4th and 5th lockdown weeks. The same pattern was found on data from Greek citizens (N=129, p<0.041). These results suggest that lockdown measures may have affected how people evaluated their social support while in lockdown, leading to a decreased sense of loneliness.

This study describes the clinical evolution and predictors of symptom persistence during 2 months' follow-up in adults with noncritical COVID-19 disease.  At D30, 68% (103/150) of patients had at least one symptom; and at D60, 66% (86/130) had symptoms, mainly anosmia/ageusia: 59% (89/150) at symptom onset, 28% (40/150) at D30 and 23% (29/130) at D60. Dyspnoea concerned 36.7% (55/150) patients at D30 and 30% (39/130) at D60. Half of the patients (74/150) at D30 and 40% (52/130) at D60 reported asthenia. Persistent symptoms at D60 were significantly associated with age 40 to 60 years old, hospital admission and abnormal auscultation at symptom onset. At D30, severe COVID-19 and/or dyspnoea at symptom onset were additional factors associated with persistent symptoms. Up to 2 months after symptom onset, two thirds of adults with noncritical COVID-19 had complaints, mainly anosmia/ageusia, dyspnoea or asthenia.

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

This study demonstrates that crowdsourced cough audio samples acquired on smartphones across the world and paired with COVID-19 status labels can be used to develop an AI algorithm that accurately predicts COVID-19 infection with an ROC-AUC of 77.1% (75.2%-78.3%). Furthermore, this AI algorithm is able to generalize to crowdsourced samples from Latin America and clinical samples from South Asia, without further training using the specific samples. As more crowdsourced data is collected, further development can be implemented using various respiratory audio samples to create a cough analysis-based AI solution for COVID-19 detection that can likely generalize globally to all demographic groups in both clinical and non-clinical settings.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

This study designed an intelligent computing paradigm through Levenberg–Marquardt artificial neural networks (LMANNs) for solving the mathematical model of COVID-19 disease propagation via human to human interaction. The model is represented with systems of nonlinear ordinary differential equations represented with susceptible, exposed, symptomatic and infectious, super spreaders, infection but asymptomatic, hospitalized, recovery and fatality classes, and reference dataset of the COVID-19 model is generated by exploiting the strength of explicit Runge–Kutta numerical method for metropolitans of China and Pakistan including Wuhan, Karachi, Lahore, Rawalpindi and Faisalabad. The created dataset is arbitrary used for training, validation and testing processes for each cyclic update in Levenberg–Marquardt backpropagation for numerical treatment of the dynamics of COVID-19 model. The effectiveness and reliable performance of the design LMANNs are endorsed on the basis of assessments of achieved accuracy in terms of mean squared error based merit functions, error histograms and regression studies

A total of 1105 inpatients with COVID-19, 967 subjects with without T2DM (n=522 male, 54.0%) and 138 subjects with pre-existing T2DM (n=82 male, 59.4%) were included. The complications were also markedly increased in patients with pre-existing T2DM, including acute respiratory distress syndrome (ARDS) (48.6% vs 32.3%, p<0.001), acute cardiac injury (ACI) (36.2% vs 16.7%, p<0.001), acute kidney injury (AKI) (24.8% vs 9.5%, p<0.001), coagulopathy (24.8% vs 11.1%, p<0.001), and hypoproteinemia (21.2% vs 9.4%, p<0.001). The in-hospital mortality was significantly higher in patients with pre-existing T2DM compared with those without T2DM (35.3% vs 17.4%, p<0.001). Moreover, in hospitalized patients with COVID-19 with T2DM, ARDS and coagulopathy were the main causes of mortality, with an HR of 7.96 (95% CI 2.25 to 28.24, p=0.001) for ARDS and an HR of 2.37 (95% CI 1.08 to 5.21, p=0.032) for coagulopathy. This was different from inpatients with COVID-19 without T2DM, in whom ARDS and cardiac injury were the main causes of mortality, with an HR of 12.18 (95% CI 5.74 to 25.89, p<0.001) for ARDS and an HR of 4.42 (95% CI 2.73 to 7.15, p<0.001) for cardiac injury.

This study examined the prevalence of anxiety and sleep disturbance at the early stage of the pandemic, and unveiled the information coping process underlying differential susceptibility to COVID-19 infection anxiety and sleep disturbance. The participants were 1,270 adults (47% men, M(age) = 42.82) from the UK and US who completed initial (Time 1) and follow-up (Time 2) surveys. The prevalence of probable clinically relevant anxiety was 61% and 45% at the first and second time points, and more than half of the participants in this anxiety group also reported mild to severe sleep disturbance. Moreover, 41% of the participants perceived themselves as not having enough COVID-19-related information and reported higher levels of COVID-19 infection anxiety and sleep disturbance over time than those who perceived themselves as having enough of such information. Moderated mediation analysis identified two groups who were more vulnerable to both psychological problems: high blunters who sought COVID-19-related information online more frequently and high monitors who sought such information offline less frequently.

We evaluated the association between a history of asthma and mortality and morbidity related to COVID-19. In this study population, 2.3% (n=96) of the patients were diagnosed with comorbid COVID-19 and asthma, while most (n=3,961) did not have asthma. The mortality rate was 8.3% (8/96) in patients with asthma and 3.0% (118/3,961) in those without asthma (p=0.009). After adjustment for multiple variables, the risk of mortality was 2.20 (95% CI =1.02-4.76, p=0.045) in patients with asthma compared with those without asthma. Subgroup analyses based on past medical history showed that among the patients with asthma, those with heart failure and chronic heart disease had an elevated risk of mortality (HR=31.61, 95% CI=4.36-229.05, p<0.001; HR=4.68, 95% CI=1.30-16.84, p=0.018, respectively).

Our findings show that the probability of molecular confirmation of Ag RDT positive results is directly dependent from the semi-quantitative results of this Ag RDT, and that the molecularly confirmed samples actually harbor infectious virus. These results support the public health strategies based on early screening campaigns in settings where molecular testing is not feasible or easily accessible, using rapid and simple point of care tests, able to rapidly identify those subjects who are at highest risk of spreading SARS-CoV-2 infection.

Overall detection was 85.71%, 47.62%, and 44.05% for Bioclin, Livzon, and Wondfo, respectively, with a specificity of 100%, and 98.75% for Livzon on storage serum samples. Bioclin was more sensitive (p<0.01), regardless of the DPS. Thus, the Bioclin can be used as a POC test to monitor SARS-CoV-2 seroconversion in HCW.

The objective of this work is to present a machine learning approach to identify regions that should implement similar health policies. For that end, we successfully developed a system that gives a notion of economic impact given the prediction of new incidental cases through unsupervised learning and time series forecasting. This system was built taking into account computational restrictions and low maintenance requirements in order to improve the system's resilience. Finally this system was deployed as part of a web application for simulation and data analysis of COVID-19, in Colombia, available at (this https URL).

Higher ACE2 expression levels in epicardial than subcutaneous stromal cells from patients with cardiovascular disease: Diabetes and obesity as possible enhancer

Couselo-Seijas,  M,  Almengló, et al

Eur J Clin Invest

Clinical data| Données cliniques

Because epicardial adipose tissue (EAT) express ACE2, we wanted to identify the main factors associated with ACE2 levels and its cleavage enzyme, ADAM17 in epicardial fat.  Epicardial expressed higher levels of ACE2 in comparison with subcutaneous fat cells, which is enhanced by diabetes and obesity presence in patients with cardiovascular disease. Both might be risk factors for SARS-CoV-2 infection.

Autosomal Dominant Polycystic Kidney Disease does not significantly alter major COVID-19 outcomes among veterans

Cui,  Xiangqin,  Gallini, et al

medRxiv

Epidemiology| Épidémiologie Clinical data| Données cliniques

To explore whether the most common inherited cause of chronic kidney disease (CKD), autosomal dominant polycystic kidney disease (ADPKD), is also an independent risk factor, we studied data from the VA health system and the VA COVID-19-shared resources. Among 61 COVID-19-positive ADPKD patients, 21 (34.4%) were hospitalized, 10 (16.4%) were admitted to ICU, 4 (6.6%) required ventilator, and 4 (6.6%) died by August 18, 2020. ADPKD was not a significant risk factor for any of the four outcomes in multivariable logistic regression analyses when compared with other cystic kidney diseases and cystic liver-only diseases. In summary, ADPKD did not significantly alter major COVID-19 outcomes among veterans when compared to other cystic kidney and liver patients.

Dalai,  CK,  Sarkar, et al

Indian Journal of Biochemistry and Biophysics

Clinical data| Données cliniques Therapeutics| Thérapeutique

This institute based study sought to assess the acute adverse effects of hydroxychloroquine among in-house health care professionals who were taking the drug for COVID-19 prophylaxis. The participants (n=54) had taken prophylaxis for 1-7 weeks. The most common adverse effects in the cohort were nausea (02) and skin rash (02). The total number of adverse effects reported by the participants was 08. One incidence each of gastric upset (01), dizziness (01), pain abdomen (01), and chest tightness (01) was reported. None of the adverse effects were serious. Our study indicates that the prophylactic weekly single dose of hydroxychloroquine is not associated with any serious adverse effects within 1-7 weeks of initiation.

World Allergy Organ J

Epidemiology| Épidémiologie Clinical data| Données cliniques

We investigated the putative interplay existing between allergen-specific immunotherapy and COVID-19 infection in a Hymenoptera venom-allergic population. We evaluated the frequency and severity of COVID-19 infection in a cohort of 211 subjects referring to our center for the regular administration of venom immunotherapy (VIT). We reported only an isolated positivity of COVID-19 in the overall group; whereas none suffered from upper airway symptoms associated with COVID-19. Even though the demographic characteristics pose a substantial risk for such a population, we suggest that a regular administration of VIT may help in the development of an immunological milieu able to down modulate the Th1/Th17 environment that has been linked to inflammatory manifestations of COVID-19.

A randomized, multicentre, open-label phase II proof-of-concept trial investigating the clinical efficacy and safety of the addition of convalescent plasma to the standard of care in patients hospitalized with COVID-19: the Donated Antibodies Working agai

Devos,  T,  Geukens, et al

Trials

RCT

BACKGROUND: The COVID-19 pandemic has imposed an enormous burden on health care systems around the world. In the past, the administration of convalescent plasma of patients having recovered from SARS and severe influenza to patients actively having the disease showed promising effects on mortality and appeared safe. Whether or not this also holds true for the novel SARS-CoV-2 virus is currently unknown. METHODS: DAWn-Plasma is a multicentre nation-wide, randomized, open-label, phase II proof-of-concept clinical trial, evaluating the clinical efficacy and safety of the addition of convalescent plasma to the standard of care in patients hospitalized with COVID-19 in Belgium. Patients hospitalized with a confirmed diagnosis of COVID-19 are eligible when they are symptomatic (i.e. clinical or radiological signs) and have been diagnosed with COVID-19 in the 72 h before study inclusion through a PCR (nasal/nasopharyngeal swab or bronchoalveolar lavage) or a chest-CT scan showing features compatible with COVID-19 in the absence of an alternative diagnosis. Patients are randomized in a 2:1 ratio to either standard of care and convalescent plasma (active treatment group) or standard of care only. The active treatment group receives 2 units of 200 to 250 mL of convalescent plasma within 12 h after randomization, with a second administration of 2 units 24 to 36 h after ending the first administration. The trial aims to include 483 patients and will recruit from 25 centres across Belgium. The primary endpoint is the proportion of patients that require mechanical ventilation or have died at day 15. The main secondary endpoints are clinical status on day 15 and day 30 after randomization, as defined by the WHO Progression 10-point ordinal scale, and safety of the administration of convalescent plasma. DISCUSSION: This trial will either provide support or discourage the use of convalescent plasma as an early intervention for the treatment of hospitalized patients with COVID-19 infection. TRIAL REGISTRATION: ClinicalTrials.gov NCT04429854 . Registered on 12 June 2020 - Retrospectively registered.

Clinical data| Données cliniques Therapeutics| Thérapeutique

In this open-label, controlled clinical trial, asymptomatic individuals who had direct contact with laboratory-confirmed COVID-19 cases or had undertaken international travel in the last 2 weeks were offered HCQ prophylaxis and assigned to PEP (n = 132) or control (n = 185) group. The PEP group received HCQ 800 mg on Day 1 followed by 400 mg once weekly for 3 weeks. Both groups undertook home quarantine for 2 weeks along with social distancing and personal hygiene. Over 4-week follow-up, 50/317 participants (15.8%) had new-onset COVID-19. The incidence of COVID-19 was significantly (P = 0.033) lower in the PEP (14/132; 10.6%) compared to the control (36/185; 19.5%) group (total absolute risk reduction, –8.9% points).

The AI system outperformed physicians in the AUROC overall (70% increase in sensitivity and 1% increase in specificity, p < 0.0001). When working with AI support, physicians increased their diagnostic sensitivity from 47% to 61% (p < 0.001), although specificity decreased from 79% to 75% (p = 0.007).

Mathematical analysis of the global COVID-19 spread in Nigeria and Spain based on seird model

Edeki,  SO,  Adinya, et al

Communications in Mathematical Biology and Neuroscience

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

In this paper, a compartmental model for the transmission dynamics of the new infectious disease referred to as COVID-19 is employed.   In the model, the temporal dynamics of the COVID-19 outbreak in Nigeria and Spain are analyzed. It shows that a decrease in the contact rate of the ‘susceptible and the infected’ classes is a considerable condition leading to a decline in 'the exposed, infected, and death' cases. This decrease is attributed to the control of the possible infecting contacts. The spread patterns for the two considered cases are the same. A lot of measures are needed to be put in place to ensure a corresponding increase in the 'recovered class.' The COVID-19 outbreak would remain global and endemic if the infecting contact rate is not well controlled.

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

We developed an automated Western immunoblotting as a complementary serologic assay for COVID-19. The Jess™ Simple Western system, an automated capillary-based assay was used.  In total, 602 sera were tested including 223 from RT-PCR-confirmed COVID-19 patients, 76 from patients diagnosed with seasonal HCoVs and 303 from coronavirus-negative control sera. In the subset of sera collected more than 2 weeks after the onset of symptoms, the sensitivity was 94% and the specificity 93%, the latter value probably reflecting cross-reactivity of SARS-CoV-2 with other coronaviruses.

Method: We conducted a Mendelian randomization study using data from UK Biobank to explore the association between alcohol consumption and risk of SARS-CoV-2 infection and serious clinical outcomes in patients with COVID-19.  Main outcomes were SARS-CoV-2 positivity and death in COVID-19 patients. Both logistic regression and Mendelian randomization analyses found no evidence that alcohol consumption was associated with risk of SARS-CoV-2 infection in participants either with or without obesity. However, frequent drinking, especially heavy drinking, was associated with higher risk of death in patients with obesity and COVID-19, but not in patients without obesity.

iScience

Clinical data| Données cliniques Animal model | Modèle animal

To test whether the olfactory neuroepithelium may represent a target of the virus, we generated RNA-seq libraries from human olfactory neuroepithelia, in which we found substantial expression of the genes coding for the virus receptor angiotensin-converting enzyme-2 (ACE2), and for the virus internalization enhancer TMPRSS2. ACE2 protein was highly expressed in a subset of sustentacular cells in human and mouse olfactory tissues. Finally, we found ACE2 transcripts in specific brain cell types, both in mice and humans. Sustentacular cells thus represent a potential entry door for SARS-CoV-2 in a neuronal sensory system that is in direct connection with the brain.

Detection of SARS-CoV-2 in wastewater in Japan during a COVID-19 outbreak

Hata,  A,  Hara-Yamamura, et al

Science of the Total Environment

Epidemiology| Épidémiologie Surveillance

Wastewater-based epidemiology (WBE) is potentially effective for early warning of a COVID-19 outbreak. In this study, presence of SARS-CoV-2 RNA in wastewater samples was investigated and was compared with the number of the confirmed COVID-19 cases in the study area during COVID-19 outbreak in Japan.  The detection frequency increased when the number of total confirmed SARS-CoV-2 cases in 100,000 people exceeded 10 in each prefecture; however, SARS-CoV-2 could also be detected at a low frequency even when the number was below 1.0. SARS-CoV-2 in wastewater could be detected in the early stage of the epidemic, even if the number of confirmed cases potentially underestimates the actual numbers of cases.

Reasons could include a reduction in self-harm at the community level and individuals avoiding presenting to hospital following self-harm.

Effect of RBD mutation (Y453F) in spike glycoprotein of SARS-CoV-2 on neutralizing antibody affinity

Hayashi,  Takuma,  Yaegashi, et al

bioRxiv

Coronavirology| Coronavirologie zoonoses

Natural selection “adaptation” in the coronavirus can occur during coronavirus amplification in vivo in farmed minks. Natural selection in such viruses is observed by introduction of mutations in SARS- CoV-2 that are not observed during the growth process in humans. Infection with a mutant (Y453F) of SARS-CoV-2 from farmed minks is known to widely spread among humans. We investigated the virological characteristics of this SARS-CoV-2 mutant (Y453F) using three-dimensional protein structural analysis. Our experimental study suggests that virus variants with the Y453F mutation partially escaped detection by four neutralizing monoclonal antibodies. The spread of SARS-CoV-2 variants mediated by millions of infected farmed minks is uncontrolled; consequently, raising a concern that infection of SARS-CoV-2 mutants that cause serious symptoms in humans may spread globally.Competing Interest StatementThe authors have declared no competing interest.

We examined the effects of the coronavirus disease 2019 (COVID-19) pandemic on first-year Japanese university students’ mental health by comparing current year's survey results with previous year's results. Accordingly, an online survey was conducted on first-year Gifu University students from April 20 to May 31, 2020. Study results revealed that, despite the emergence of the COVID-19 pandemic, the number of “high-risk” students and the depression level were lower among the 2020 first-year students compared to previous year's students. However, the 2020 first-year students experienced high academic distress since they had to adapt to an unfamiliar e-learning environment. © 2020

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

One of the ways in which the death of COVID-19 can be reduced is to produce a prediction model that could be used as a reference in taking countermeasures. There are various prediction models, from regression to Autoregressive Fractional Integrated Moving Average (ARIMA), but it still shows shortcomings when disturbances occur from extreme fluctuations and the existence of long memory effects in the form of analysis of a series of data becomes biased, and the power of statistical tests generated for identification become weak. The results of this study prove that ARFIMA (1,0,431.0) with an RMSE of 2,853 is the best model to predict data on the addition of new cases of patients dying from COVID-19.

Controlled human infection (CHI) models for the novel coronavirus (SARS-CoV-2) have been proposed as a tool to accelerate the development of vaccines and drugs. Such models carry inherent risks. Participants may develop severe disease or complications after deliberate infection. Prolonged isolation may negatively impact their wellbeing. Through secondary infection of study personnel or participant household contacts, the experimental virus strain may cause a community outbreak. We identified risks associated with such a SARS-CoV-2 CHI model and assessed their likelihood and impact and propose strategies that mitigate these risks. In this report, we show that risks can be minimized with proper risk mitigation strategies; the residual risk however should be weighed carefully against the scientific and social values of such a CHI model.

Anxiety and depression levels were significantly interacted with the presence of housemates (p = 0.042, p = 0.031, respectively).  A multiple regression analysis indicated that being female and staying at home (with close contact) increased the degree of both anxiety and depression while the presence of housemates increased anxiety levels only. Workers without close contact with COVID-19 patients were divided into three groups: no change in work, transfer to the COVID-19 ward, and transfer to other wards. These instructions did not affect workers’ anxiety and depression levels (p > 0.05, respectively)

Clinical data| Données cliniques Immunology | Immunologie

SARS-CoV-2-specific T cells in individuals who clear SARS-CoV-2 infection without symptoms or disease could reveal non-pathological yet protective characteristics. We therefore compared the quantity and function of SARS-CoV-2-specific T cells in a cohort of asymptomatic individuals (n=85) with that of symptomatic COVID-19 patients (n=76), at different time points after antibody seroconversion.  We detected an increased IFN-γ and IL-2 production in asymptomatic compared to symptomatic individuals after activation of SARS-CoV-2-specific T cells in blood. This was associated with a proportional secretion of IL-10 and pro-inflammatory cytokines (IL-6, TNF-α and IL-1β) only in asymptomatic infection, while a disproportionate secretion of inflammatory cytokines was triggered by SARS-CoV-2-specific T cell activation in symptomatic individuals. Thus, asymptomatic SARS-CoV-2 infected individuals are not characterized by a weak antiviral immunity; on the contrary, they mount a robust and highly functional virus-specific cellular immune response. Their ability to induce a proportionate production of IL-10 might help to reduce inflammatory events during viral clearance.

Brain MRI abnormalities, especially leptomeningeal enhancement, and increased inflammatory markers in CSF are frequent in patients with neurological manifestations related to COVID-19, whereas SARS-CoV 2 detection in CSF remained scanty.

A model of COVID-19 propagation based on a gamma subordinated negative binomial branching process

Levesque,  J,  Maybury, et al

Journal of theoretical biology

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We build a parsimonious Crump-Mode-Jagers continuous time branching process of COVID-19 propagation based on a negative binomial process subordinated by a gamma subordinator. By focusing on the stochastic nature of the process in small populations, our model provides decision making insight into mitigation strategies as an outbreak begins. Our model accommodates contact tracing and isolation, allowing for comparisons between different types of intervention. We emphasize a physical interpretation of the disease propagation throughout which affords analytical results for comparison to simulations.  Combining the asymptotic limit of our model with Bayesian hierarchical techniques, we provide US county level inferences for the reproduction number from cumulative case count data over July and August of this year.

Effects of simulation training on COVID-19 control ability and psychological states of nurses in a children's hospital

Li,  DF,  Shi, et al

European review for medical and pharmacological sciences

Healthcare Response | Réponse des soins de santé

This study aims to discuss the effects of simulation training on improving the pre-examination, triage, prevention, and control of coronavirus disease 2019 (COVID-19), explain the psychological states of pre-examination and triage staff in general hospitals during the COVID-19 epidemic, and analyze relevant influencing factors. The percent of passing significantly increased from 65% before the training to 98.33% after training (p<0.05). Training also significantly relieved the anxiety and depression of the nurses (p<0.05). In conclusion, scenario-simulation training can increase the emergency abilities of pediatric nurses in the prevention and control of the COVID-19 epidemic and relieve the anxiety of nurses.

Dynamic changes in anti-SARS-CoV-2 antibodies during SARS-CoV-2 infection and recovery from COVID-19

Li,  K,  Huang, et al

Nat Commun

Clinical data| Données cliniques Immunology | Immunologie

We analyze the laboratory findings of 1,850 patients to describe the dynamic changes of the total antibody, spike protein (S)-, receptor-binding domain (RBD)-, and nucleoprotein (N)-specific immunoglobulin M (IgM) and G (IgG) levels during SARS-CoV-2 infection and recovery.  The generation of S-, RBD-, and N-specific IgG occurs one week later in patients with severe/critical COVID-19 compared to patients with mild/moderate disease, while S- and RBD-specific IgG levels are 1.5-fold higher in severe/critical patients during hospitalization. The RBD-specific IgG levels are 4-fold higher in older patients than in younger patients during hospitalization. In addition, the S- and RBD-specific IgG levels are 2-fold higher in the recovered patients who are SARS-CoV-2 RNA negative than those who are RNA positive. Lower S-, RBD-, and N-specific IgG levels are associated with a lower lymphocyte percentage, higher neutrophil percentage, and a longer duration of viral shedding. Patients with low antibody levels on discharge might thereby have a high chance of being tested positive for SARS-CoV-2 RNA after recovery.

The Relationship between Weekly Periodicity and COVID-19 Progression

Li,  Sophia

medRxiv

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We investigate the weekly periodicity in the daily reported new cases and new deaths with the implied relationships to the societal and institutional responses using autocorrelation and Fourier transformation. The results show significant linear correlations between the weekly periodicity and the total cases and deaths, ranging from 50% to 84% for sizable groups of countries with population normalized deaths spanning nearly three orders of magnitude, from a few to approaching a thousand per million. In particular, the Strength Indicator of the periodicity in the new cases, defined by the autocorrelation with a 7-day lag, is positively correlated strongly to the total deaths per million in respective countries. The Persistence Indicator of the periodicity, defined as the average of three autocorrelations with 7-, 14- and 21-day lags, is an overall better indicator of the progression of the pandemic. For longer time series, Fourier transformation gives similar results.  This analysis begins to fill the gap in modeling and simulation of epidemics with the inclusion of high frequency modulations, in this case most likely from human behaviors and institutional practices, and reveals that they can be highly correlated to the magnitude and duration of the pandemic. The results show that there is significant need to understand the causes and effects of the periodicity and its relationship to the progression and outcome of the pandemic, and how we could adapt our strategies and implementations to reduce the extent of the impact of COVID-19.

A serological aptamer-assisted proximity ligation assay for COVID-19 diagnosis and seeking neutralizing aptamers

Liu,  R,  He, et al

Chemical Science

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

Here we report a generalizable method for highly specific and ultrasensitive detection of serum COVID-19-associated antigens based on an aptamer-assisted proximity ligation assay. The sensor is based on binding two aptamer probes to the same protein target that brings the ligation DNA region into close proximity, thereby initiating ligation-dependent qPCR amplification. Using this system, serum nucleocapsid protein has been detected quantitatively by converting protein recognition into a detectable qPCR signal using a simple, homogeneous and fast detection workflow in 2 hours. In addition, this system has also been transformed into a universal platform for measuring specific interactions between spike S1 and its receptor ACE2, and more importantly demonstrated the feasibility for screening and investigation of potential neutralizing aptamers.

Expressions of SAA, CRP, and FERR in different severities of COVID-19

OBJECTIVE: To explore the expression and significance of SAA, CRP and FERR in patients diagnosed with COVID-19.  A total of 225 patients diagnosed with COVID-19 who were admitted to the North Hospital of First Hospital in Changsha, China, from 9th February 2020 to 7th March 2020 were enrolled. Age was an important risk factor for the severity of COVID-19 in the patients. Compared with the non-severe group, the severe group showed statistical significance in the levels of total protein, albumin, ALT and AST in liver function, UA in renal function, myocardial enzyme CK-MB and LDH, and immunoglobulin IgG and IgM. The levels of SAA, CRP, and FERR were significantly increased in patients with severe COVID-19. The sensitivity and specificity of the combined detection of the three indicators were higher than those of the detection of any single indicator or two combined indicators.

Here, we showed that immunization of mice with a candidate subunit vaccine consisting of SARS-CoV-2 RBD and Fc fragment of human IgG, as an immunopotentiator, elicited high titer of RBD-specific antibodies with robust neutralizing activity against both pseudotyped and live SARS-CoV-2 infections. The mouse antisera could also effectively neutralize infection by pseudotyped SARS-CoV-2 with several natural mutations in RBD and the IgG extracted from the mouse antisera could also show neutralization against pseudotyped SARS-CoV and SARS-related coronavirus (SARSr-CoV). Vaccination of human ACE2 transgenic mice with RBD-Fc could effectively protect mice from the SARS-CoV-2 challenge.

Data for COVID-19 patients with clinical outcome in a designated hospital in Wuhan, China, were retrospectively collected and analyzed from 30 January 2020 to 20 February 2020.  Of 298 patients enrolled, 84 died and 214 recovered. Most nonsurvivors were male, older, or with chronic diseases. Compared with survivors, nonsurvivors showed significantly elevated white blood cell and neutrophil counts, neutrophil to lymphocyte ratio (NLR), systemic immune inflammation index (defined by platelet count multiplied by NLR), CRP, procalcitonin, and D-dimer and showed decreased red blood cell, lymphocyte, and platelet counts. Age, neutrophil count, platelet count, and CRP were identified as independent predictors of adverse outcome.  CRP exhibited sensitivity of 90.5%, specificity of 77.6%, positive predictive value of 61.3%, and negative predictive value of 95.4%. CRP was also an independent discriminator of severe/critical illness on admission with an AUC (0.783) comparable to age (0.828) and neutrophil count (0.729) (both P > .05).

U-Earth AIRcel bioreactors are a demonstrated effective biomonitoring system. We implemented a methodological approach wherein they were placed at various hospitals treating COVID-19 patients in Italy. The objective of the study was to investigate if U-Earth AIRcel bioreactors were effective in monitoring and improving air quality via detection, capture, and destruction of the SARS-CoV-2 virus, reducing the risk of transmission among healthcare workers. The marked presence of the SARS-CoV-2 virus was found in multiple water samples via the detection of ORF1ab + N and/or E gene involved in gene expression and cellular signaling of the SARS-CoV virus. The AIRcel bioreactors were able to neutralize the virus effectively as traces of the viruses were no longer found in multiple solute samples after an overnight period

SARS‐CoV‐2 infection causes an abrupt response by the host immune system, which is largely responsible for the outcome of COVID‐19. We investigated whether the specific immune responses in the peripheral blood of 276 patients associated to severity and progression of COVID‐19. At admission, dramatic lymphopenia of T, B and NK cells associated to severity. Conversely, the proportion of B cells, plasmablasts, circulating follicular helper T cells (cTfh) and CD56‐CD16+ NK‐cells increased. Regarding humoral immunity, levels of IgM, IgA and IgG were unaffected, but when degrees of severity were considered, IgG was lower in severe patients. Compared to healthy donors, complement C3 and C4 protein levels were higher in mild and moderate, but not in severe patients, while the activation peptide of C5 (C5a) increased from the admission in every patient, regardless their severity. Moreover, total IgG, the IgG1 and IgG3 isotypes and C4 decreased from day 0 to day 10 in patients who were hospitalized for more than two weeks, but not in patients who were discharged earlier.

We evaluated the seroprevalence of anti-SARS-CoV-2 in blood donors in Nuevo Leon, Mexico as a strategy for asymptomatic case detection of COVID-19 and epidemic progression. We found 77 donors reactive for anti-SARS-CoV-2 IgG (seroprevalence 3.99%) and none of them had reported recent COVID-19 symptoms. Donors aged 18 to 49 years (89.5%) were more likely to be seropositive compared to those aged 50 years or older (10.5%) (P<0.001). Prevalence of antibodies increased each epidemiological (EPI) week, parallel to the report of confirmed cases by RT-PCR, identifying the highest prevalence between EPI week 33 and 35 (10.2% to 19%). The metropolitan area of Monterrey recorded the highest number of cases.

The purpose of this study was to develop and internally validate a predictive model to aid in the discrimination of patients undergoing investigation for COVID‐19. 1026 patients were included in the study collected between March and April 2020. Overall, there was disease prevalence of 9.6% in the population under study during this time frame. The logistic regression model was found to have an AUC of 0.89 (95% CI 0.84 ‐ 0.94) when including four features: exposure history, temperature, WBC, and chest radiograph result. Random forest method resulted in AUC of 0.86 (95% CI 0.79 ‐ 0.92) and gradient boosting had an AUC of 0.85 (95% CI 0.79‐0.91). With a consistently held negative predictive value, the logistic regression model had a positive predictive value of 0.29 (0.2‐0.39) compared to 0.2 (0.14‐0.28) for random forest and 0.22 (0.15 – 0.3) for the gradient boosted method.

Epidemiology| Épidémiologie

By interpreting the portion of positive tests as a positive rate, we find the positive rate and the numbers of deceased to run parallel with an offset of about 13 days. This has been observed worldwide in ten other countries and locally in Germany and North Rhine-Westphalia. The daily positive ratio, which is reported by state health authorities, allows to estimate the number of deaths (and seriously ill people) about 13 days ahead. This gives local hospitals more time for detailed planning.

The health crisis caused by SARS-Cov2 continues to question the scientific community on an effective treatment to combat the disease. To do this, understanding the pathophysiology is a key element. Although the use of corticosteroids is debated, recent publications on pathogenesis and histologic pattern allow us to consider their use on a different way. Through these two case reports, it seemed interesting to take stock of the most recent data in the literature and on the potential interest of the corticotherapy in specific critically ill patient's cases.

We consider an SIR model on a network and follow the disease dynamics, modeling the phases of quarantine by changing the node degree distribution. We show that the system reaches different steady states based on the history: the outcome of the epidemic is path-dependent despite the same final node degree distribution. The results indicate that two-phase route to the final node degree distribution (a strict phase followed by a soft phase) are always better than one phase (the same soft one) unless all the individuals have the same number of connections at the end.

Retrospective observational study of all Covid-19 patients admitted to the main hospital of Bergamo, from February 23 to March, 14, 2020. 508 patients were hospitalized , predominantly male (72.4%), mean age of 66±15 years; 49.2% were older than 70 years. At the peak of the outbreak, with a probable high infectious dose and viral load, older age, the severity of respiratory failure and renal impairment at presentation, but not comorbidities, are predictors of 28-day mortality in Covid-19.

Triage Into the Community for COVID-19 (TICC-19) Patients Pathway - Service evaluation of the virtual monitoring of patients with COVID pneumonia

Nunan,  J,  Clarke, et al

Acute medicine

Healthcare Response | Réponse des soins de santé

Safe triage and follow up systems are required to manage this unprecedented demand. We designed a pathway for the triage and assessment of patients based on their resting oxygen saturations and response to a 30 metre rapid walking test. During the first wave of COVID-19 we entered 273 onto the pathway for Virtual Ward follow up. Of these, 31 patients were readmitted to hospital, two were admitted to Intensive Care and one patient died. It is safe, feasible and cost effective to set up a triage system with remote oximetry monitoring for patients with COVID-19 and overwhelmingly patients find it a positive experience.

The Qatar Prospective RCT of Expediting Coronavirus Tapering (Q-PROTECT) aimed to assess virologic cure rates of HC±AZ in cases of low-acuity Covid-19. The study enrolled 456 participants (152 in each of three groups: HC+AZ, HC, placebo) between 13 April and 1 August 2020. HC+AZ, HC, and placebo groups had 6 (3·9%), 7 (4·6%), and 9 (5·9%) participants go off study medications before completing the medication course (p = 0·716). Day six ITT analysis found no difference (p = 0·821) in groups’ proportions achieving virologic cure; and day 14 assessment also showed no association (p = 0·072) between study group and viral cure. HC±AZ does not facilitate virologic cure in patients with mild or asymptomatic Covid-19.

We  studied  the  prognostic  value  of  the  Quick Walk Test (QWT)  for  patients  suspected  of  COVID-19  during  an outbreak, focusing on the need for invasive mechanical ventilation (MV) within 15 days from the first ED access as outcome. As median times from illness onset to clinical deterioration of 8.44 or 14.55 days have been reported, a follow up of 15 days was chosen to capture most of the severe clinical deteriorations, while excluding events that were not directly related to the severity of the COVID-19 infection.

Multi-chain Fudan-CCDC model for COVID-19—a revisit to Singapore’s case

Pan,  H,  Shao, et al

Quantitative Biology

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

We propose the multi-chain Fudan-CCDC model based on the original single-chain model in [Shao et al. 2020] to describe the evolution of COVID-19 in Singapore. Multi-chains can be considered as the superposition of several single chains with different characteristics. We identify the parameters of models by minimizing the penalty function. The multi-chain Fudan-CCDC model provides an effective way to early detect the appearance of imported infectors and super spreaders and forecast a second outbreak. It can also explain the data from those countries where the single-chain model shows deviation from the data.

We aim to estimate the infection fatality risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), based on deaths with confirmed coronavirus disease 2019 (covid-19) and excess deaths from all causes. The main outcome measure was overall, and age and sex specific, infection fatality risk for SARS-CoV-2 in the community dwelling Spanish population. The overall infection fatality risk was 0.8% (19 228 of 2.3 million infected individuals, 95% confidence interval 0.8% to 0.9%) for confirmed covid-19 deaths. The increase in SARS-CoV-2 infection fatality risk after age 50 appeared to be more noticeable in men than in women. Based on the results of this study, fatality from covid-19 was greater than that reported for other common respiratory diseases, such as seasonal influenza.

To provide better understanding of mild SARS-CoV-2 infections and to improve information for potentially infected individuals, we performed a detailed analysis of self-reported symptoms of SARS-CoV-2 positive and SARS-CoV-2 negative individuals. The symptoms reported most frequently by SARS-CoV-2 infected individuals were tiredness, loss of appetite, impairment of smell or taste and dry cough. The symptoms with the highest odds ratios between SARS-CoV-2 positive and negative individuals were loss of appetite and impairment of smell or taste.  A combination of symptoms can provide a good estimate of the probability of SARS-CoV-2 infection.

Mental health of Urban Mothers (MUM) study: a multicentre randomised controlled trial, study protocol

Schwank,  SE,  Chung, et al

BMJ Open

RCT

INTRODUCTION: Mental health disorders are common during pregnancy and the postnatal period and can have serious adverse effects on women and their children. The consequences for global mental health due to COVID-19 are likely to be significant and may have a long-term impact on the global burden of disease. Besides physical vulnerability, pregnant women are at increased risk of mental health problems such as anxiety, depression and post-traumatic stress disorder due to the consequences of social distancing. It can result in altered healthcare routines, less support from the family and friends, and in some cases, partners not being allowed to be present during prenatal visits, labour and delivery. Higher than expected, rates of perinatal anxiety and depression have been already reported during the pandemic. Pregnant women may also feel insecure and worried about the effects of COVID-19 on their unborn child if they get infected during pregnancy. Today, young urban women are used to using internet services frequently and efficiently. Therefore, providing mental health support to pregnant women via internet may be effective in ameliorating their anxiety/depression, reducing the risk of serious mental health disorders, and lead to improved maternal and perinatal outcomes. OVERARCHING AIM: Our aim is to explore the effectiveness of a web-based psychosocial peer-to-peer support intervention in reducing the risk and severity of perinatal mental health disorders and preventing adverse pregnancy outcomes among pregnant women living in metropolitan urban settings. METHODS AND ANALYSIS: We plan to conduct a multicentre prospective randomised controlled trial, Mental health of Urban Mothers trial. Pregnant women living in large metropolitan cities will be recruited using internet-based application through non-profit organisations' websites. The women who consent will be randomised to receive a web-based peer-to-peer support intervention or usual care. Data will be analysed to identify the effects of intervention on Edinburgh Postnatal Depression Score and Generalised Anxiety Disorder 7 scores as well as pregnancy outcomes. The impact of COVID-19 pandemic on maternal stress will be assesed using Impact Event Scale-R. Any differences in outcomes between cities will be addressed in subgroup analyses. ETHICS AND DISSEMINATION: The study will be conducted according to the principles of Good Clinical Practice and will follow the ethical principles of the Declaration of Helsinki. The study protocol has been approved by the ethical review board of Chinese University of Hong Kong (IRB number 2019-8170) and Shanghai Center for Women's and Children's Health (international review board (IRB) number 2020-F001-12). The results will be disseminated at national and international scientific conferences, published in peer-reviewed medical journals and spread to the public through social media, news outlets and podcasts.

This study aimed to estimate the age-stratified and overall morbidity and mortality rates of SARS-CoV-2 infection based on an analysis of the epidemic in Qatar.  All outcomes showed very strong age dependence, with low values for those <50 years of age, but rapidly growing rates for those ≥50 years of age. The strong age dependence was particularly pronounced for infection criticality rate and infection fatality rate.

Potential SARS-CoV-2 interactions with proteins involved in trophoblast functions – An in-silico study

Seethy,  AA,  Singh, et al

Placenta

Coronavirology| Coronavirologie

We explored in silico, the potential interactions between SARS-CoV-2 proteins and proteins involved in the key functions of placenta.  The entry receptors for SARS-CoV-2 – ACE2 and TMPRSS2 are expressed in placenta. SARS-CoV-2 can potentially interact with proteins having crucial roles in the placental function. Whether these potential interactions identified in silico have effects on trophoblast functions in biological settings needs to be addressed by further in vitro and clinical studies.

A recursive bifurcation model for early forecasting of COVID-19 virus spread in South Korea and Germany

Shen,  J

Sci Rep

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie

In this paper we design a recursive bifurcation model for analyzing COVID-19 virus spread in different countries. The bifurcation facilitates recursive processing of infected population through linear least-squares fitting. In addition, a nonlinear least-squares fitting procedure is utilized to predict the future values of infected populations. Numerical results on the data from two countries (South Korea and Germany) indicate the effectiveness of our approach, compared to a logistic growth model and a Richards model in the context of early forecast.

Transmission Clinical data| Données cliniques Immunology | Immunologie

The objective of this prospective observational study was to evaluate the clinical course of COVID-19 during pregnancy and maternal and perinatal outcomes of this pregnancy. 66 women with PCR confirmed SARS-CoV-2 and their 42 neonates were included. Mostly, the manifestations of COVID-19 were mild. However, 9% of cases were severe, and could contribute to preterm delivery or maternal morbidity. Main predictors of severe COVID-19 course in pregnant women were a decrease in the levels of erythrocytes and lymphocytes and increase in the levels of alanine aminotransferase and CRP. Elimination of the virus in pregnant women required more time due to altered immunity. No evidence of vertical transmission during pregnancy and delivery was found.

Pattern Recognition

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

Various AI functionalities such as pattern recognition and prediction can effectively be used to diagnose (recognize) and predict coronavirus disease 2019 (COVID-19) infections and propose timely response (remedial action) to minimize the spread and impact of the virus. Motivated by this, an AI system based on deep meta learning has been proposed in this research to accelerate analysis of chest X-ray (CXR) images in automatic detection of COVID-19 cases. We present a synergistic approach to integrate contrastive learning with a fine-tuned pre-trained ConvNet encoder to capture unbiased feature representations and leverage a Siamese network for final classification of COVID-19 cases. We validate the effectiveness of our proposed model using two publicly available datasets comprising images from normal, COVID-19 and other pneumonia infected categories. Our model achieves 95.6% accuracy and AUC of 0.97 in diagnosing COVID-19 from CXR images even with a limited number of training samples. © 2020 Elsevier Ltd

Characteristics of COVID-19 patients admitted to a tertiary care hospital in Pune, India, and cost-effective predictors of intensive care treatment requirement

Shukla,  UrviB,  Shukla, et al

medRxiv

Clinical data| Données cliniques

Studied the associations of severity of disease and need for ICU treatment in COVID-19 patients. Average age was 41 years, 16% were <20 years of age, 55% were male, 50% were asymptomatic and 16% had at least one comorbidity. Using MoHFW India severity guidelines, 73% patients had mild, 6% moderate and 20% severe disease. Severity was associated with higher age, symptomatic presentation, elevated neutrophil and reduced lymphocyte counts and elevated inflammatory markers. Seventy-seven patients needed ICU treatment: they were older (56 years), more symptomatic and had lower SpO2 and abnormal chest X-ray and deranged hematology and biochemistry at admission. A model trained on the first 500 patients, using above variables predicted need for ICU treatment with sensitivity 80%, specificity 88% in subsequent 300 patients; exclusion of expensive laboratory tests did not affect accuracy.

Influence of the COVID-19 Pandemic on Treatment Times for Acute Ischemic Stroke: The Society of Vascular and Interventional Neurology Multicenter Collaboration

Stroke

Healthcare Response | Réponse des soins de santé

Evaluated whether the COVID-19 pandemic may have contributed to delays in acute stroke management at comprehensive stroke centers. 1491 patients were admitted during the pre-COVID-19 period and 1464 were admitted during COVID-19, 15% of whom underwent intravenous thrombolysis. Patients treated during COVID-19 were at lower odds of receiving thrombolysis within 60 minutes of arrival (odds ratio, 0.61), with a median delay in door-to-needle time of 4 minutes. The lower odds of achieving treatment in the Target: Stroke goal persisted after adjustment for all variables associated with earlier treatment (adjusted odds ratio, 0.55). The delay in thrombolysis appeared driven by the longer delay from imaging to bolus (median, 29 minutes versus 22 minutes). There was no significant delay in door-to-groin puncture for patients who underwent thrombectomy (median, 83 minutes versus 90 minutes). Delays in thrombolysis were observed in the months of June and July.

Examined the association of smoking status with hospitalisation for COVID-19 compared with hospitalisation for other respiratory virus infections a year previous and compared current smoking in cases with age- and sex-matched London prevalence. Patients hospitalised with COVID-19 had lower odds of being current smokers than patients admitted with other respiratory viruses (ORadj=0.55). Odds were equivocal for former smokers (ORadj=1.08). Current smoking in cases was significantly lower than expected from London prevalence (9.4% vs. 12.9%). Smoking status recorded on the EHR deviated significantly from that recorded within the medical notes (χ2(3)=226.7, p<.001).

Rare Complication of Pneumomediastinum and Pneumopericardium in a Patient with COVID-19 Pneumonia

Case Reports in Pulmonology

Clinical data| Données cliniques

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a recently discovered coronavirus which has caused a global outbreak of severe pneumonia with complications leading to hypoxic respiratory failure, acute respiratory distress syndrome (ARDS), cytokine storm, disseminated intravascular coagulation (DIC), and even gastrointestinal symptoms. While ground-glass opacity (GGO) is a typical radiographic finding associated most frequently with COVID-19 pneumonia, other less commonly noted atypical radiographic lung features include isolated lobar or segmental consolidation without GGO, discrete small nodules (centrilobular, "tree-in-bud"), lung cavitation, and smooth interlobular septal thickening with pleural effusion. Pneumomediastinum in COVID-19 patients has rarely been reported. A finding of pneumopericardium is unusual too. This report discusses the case of a young male with COVID-19 pneumonia who was found to have both these features on computed tomographic (CT) scans of his chest on presentation. © 2020 Anshika Singh et al.

Heliyon

Coronavirology| Coronavirologie Vaccine Research| Recherche sur les vaccins

Used various in – silico approaches to designed vaccine against COVID-19. To develop vaccine, we target S- protein, expressed on the virus surface plays important role in COVID-19 infection. We identified 12 B-cell, 9 T-helper and 20 Cytotoxic T-cell epitope based on criteria of selection. The predicted epitopes were link simultaneously with GPGPG & AAY linkers. The β-defensin was used as adjuvant, linked with selected epitope by using EAAAK linker. For vaccine construct justification we analysed its immunogenicity, allergenicity and physiochemical properties. Our study revealed that vaccine was non toxic, immunogenic and antigenic in nature and covers 98.6% of world population, important for vaccine effectively. In- silico cloning was used to analyse its expression in vector. Molecular docking was performed to study the interaction of construct with TLR (TLR3, TLR4, and TLR9) molecules.

Coronavirology| Coronavirologie Vaccine Research| Recherche sur les vaccins

Propose a detailed and comprehensive immunoinformatic approach that can be applied to the currently available coronavirus protein data in the online server for vaccine candidate development. Identified the receptor binding domain (RBD) of structural spike protein (S1) as a potential target for immunity against COVID- 19 infection. Epitope prediction illustrated cytotoxic T-cell epitopes, helper T-cell epitopes, and B-cell epitopes associated with the target protein. These were joined through specific linkers along with adjuvant beta-defensin located at the N-terminal to create a multi epitope subunit vaccine (MESV). The specificity in the binding of the devised vaccine candidate to the TLR-3 immune cell receptor was evaluated via molecular docking interaction studies. Good docking score combined with robust interactions in the binding cavity certified the stringency of the engineered vaccine. Molecular dynamics simulation data showed minimal variation of the root-mean square deviations (RMSDs) and root-mean-square fluctuations (RMSFs) which confirmed the interaction stability.

A Novel Cell Therapy for COVID-19 and Potential Future Pandemics: Virus Induced Lymphocytes (VIL)

Coronavirology| Coronavirologie Therapeutics| Thérapeutique

Used a novel SARS-Cov-2-specific artificial antigen presenting cell (aAPC), coupled with a rapid expansion protocol (REP) as practiced in tumor infiltrating lymphocytes (TIL) therapy, we generate an immune catalytic quantity of Virus Induced Lymphocytes (VIL). Using T cell receptor (TCR)-specific aAPCs carrying co-stimulatory molecules and major histocompatibility complex (MHC) class-I immunodominant SARS-CoV-2 peptide-pentamer complexes, we expand virus-specific VIL derived from peripheral blood mononuclear cells (PBMC) of convalescent COVID-19 patients up to 1,000-fold. This is achieved in a clinically relevant 7-day vein-to-vein time-course as a potential adoptive cell therapy (ACT) for COVID-19. Also evaluated this approach for other viral pathogens using Cytomegalovirus (CMV)-specific VIL from donors as a control. Rapidly expanded VIL are enriched in virus antigen-specificity and show an activated, polyfunctional cytokine profile and T effector memory phenotype which may contribute to a robust immune response. Virus-specific T cells can also be delivered allogeneically via MHC-typing and patient human leukocyte antigen (HLA)-matching to provide pragmatic treatment in a large-scale therapeutic setting.

Report on the pharmacokinetics of remdesivir and its metabolites and the treatment outcome in a patient on renal replacement therapy without residual renal function suffering from severe COVID-19. A male patient in his mid seventies was admitted and diagnosed with COVID-19. Initially, he presented with typical pulmonary infiltrates and normal arterial blood gas results. However, the patient’s clinical status deteriorated rapidly. Ten days after admission, the patient was transferred to the ICU with hypoxaemic lung failure requiring high-flow oxygen therapy. In this critical situation, we decided to apply remdesivir, while performing extensive therapeutic drug monitoring of the prodrug and two metabolites for safety reasons. Overall, there were no signs of drug-related toxicity. By day 5 of remdesivir treatment, oxygenation parameters had improved allowing for patient transfer to a hospital ward.

Analyzed the usage of hydroxychloroquine in pediatric patients with COVID-19. The mean age of asymptomatic children (118±62 months) was found to be higher than that of symptomatic children (89±69 months). Symptomatic children had a significantly lower mean lymphocyte count and higher mean CRP, D-dimer value, procalcitonin and LDH than asymptomatic children in univariate analysis. Out of 156 children, 78 children received Hydroxychloroquine-containing regimen, 15 of them were treated with hydroxychloroquine + azithromycin + oseltamivir, 44 were treated with hydroxychloroquine + azithromycin and 21 were only treated with hydroxychloroquine. Among the 156 patients who received medical treatment, 90 patients had pre and/or post-treatment ECG performed upon them. However, none of them either reported ECG abnormalities or a need for discontinuation of hydroxychloroquine because of adverse drug reaction.

Assessed the impact of the coronavirus disease 2019 (COVID-19) pandemic on surgical volume and emergency department (ED) consults across obstetric & gynecologic (OB/GYN) services at a New York City hospital. The volume and types of surgeries and ED consults were compared before and after the COVID-19 moratorium. During the pandemic, the average weekly volume of ED consults and GYN surgeries decreased, while OB surgeries remained stable. The proportions of OBGYN ED consults, GYN surgeries, and OB surgeries relative to all ED consults, all surgeries, and all labor and delivery patients were 1.87%, 13.8%, 54.6% in the pre-COVID timeframe (February 1 to March 15) versus 1.53%, 21.3%, 79.7% in the COVID timeframe (March 16 to April 15), representing no significant difference in proportions of OBGYN ED consults and GYN surgeries before and during COVID, with proportionate increase in OB surgeries. The distribution of GYN surgical case types changed significantly during the pandemic with higher proportions of emergent surgeries for ectopics, miscarriages, and concern for cancer. Alternatively, the OB surgery distribution of case types remained relatively constant.

Evaluated the antiviral potential of selected WS phytoconstituents against the novel SARS-CoV-2 target proteins and human ACE2 receptor using in silico methods. Most of the phytoconstituents displayed good absorption and transport kinetics and were also found to display no associated mutagenic or adverse effect(s). Molecular docking analyses revealed that most of the WS phytoconstituents exhibited potent binding to human ACE2 receptor, SAR-CoV and SARS-CoV-2 spike glycoproteins as well as the two main SARS-CoV-2 proteases. Most of the phytoconstituents were predicted to undergo Phase-I metabolism prior to excretion. All phytoconstituents had favorable bioactivity scores with respect to various receptor proteins and target enzymes. SAR analysis revealed that the number of oxygen atoms in the withanolide backbone and structural rearrangements were crucial for effective binding. Molecular simulation analyses of SARS-CoV-2 spike protein and papain-like protease with Withanolides A and B, respectively, displayed a stability profile at 300 K and constant RMSDs of protein side chains and Cα atoms throughout the simulation run time.

Six cases of acute pulmonary embolism associated with COVID-19

Revue medicale de Liege

Clinical data| Données cliniques

Article in French. Rising from the province of Wuhan in China, the new coronavirus SARS-CoV-2 broke out in winter 2019, causing a global pandemic. In most cases reported, COVID-19 symptoms include cough, dyspnea, myalgia and asthenia. In some cases, the disease can also cause severe respiratory distress syndrome, requiring intensive care. Recent studies suggest that SARS-CoV-2 infection predisposes to thromboembolic event such as pulmonary embolism. Moreover, there is an overlap between signs and symptoms of pulmonary embolism and COVID-19, which brings a challenge for the diagnosis and could potentially be fatal. Nevertheless, the incidence rate of pulmonary embolism in cases of COVID-19 is currently not known. In this paper we describe six cases of pulmonary embolism associated with COVID-19.

Modelling/ prediction| Modélisation/prédiction Transmission

Propose a mathematical model for the risk analysis of airborne infectious disease in an outpatient room. Not only considering one type of person but also in this research, people are considered according to personal classifications. There are 4 types-patient, relative, worker, and outsider, staying in an outpatient room, which is in accordance with the real world. Air quality control manipulations are simulated using the inlet and outlet ventilation rates adjustment under the condition of a number of surrounding people with a personal classified factor. The fourth-order Runge-Kutta (RK4) is used to approximate the model solution. The proposed numerical model can be used to describe the dynamical dispersion of airborne infectious disease in an outpatient room. The results of the model are satisfactory, and it will be able to control airborne disease in more complicated structures.

Two Stage Transformer Model for COVID-19 Fake News Detection and Fact Checking

Vijjali,  Rutvik,  Potluri, et al

arXiv

Public Health response| Interventions de santé publique

We developed a two stage automated pipeline for COVID-19 fake news detection using state of the art machine learning models for natural language processing. The first model leverages a novel fact checking algorithm that retrieves the most relevant facts concerning user claims about particular COVID-19 claims. The second model verifies the level of truth in the claim by computing the textual entailment between the claim and the true facts retrieved from a manually curated COVID-19 dataset. The dataset is based on a publicly available knowledge source consisting of more than 5000 COVID-19 false claims and verified explanations, a subset of which was internally annotated and cross-validated to train and evaluate our models.

Epidemiology| Épidémiologie Immunology | Immunologie

Participants (n=3207, aged 2–90 years), enrolled from a previously established nationwide serosurveillance study, provided a self-collected fingerstick blood sample and completed a questionnaire (median inclusion date 3 April 2020) in this study to detect SARS-CoV-2 serum antibodies in the general population of the Netherlands and identify risk factors for seropositivity amidst the first COVID-19 epidemic wave. In the midst of the first epidemic wave, 2.8% of the Dutch population was estimated to be infected with SARS-CoV-2, that is, 30 times higher than reported. This study identified independent groups with increased odds for seropositivity that may require specific surveillance measures to guide future protective interventions internationally, including vaccination once available.

This preliminary report investigates the prevalence and features of protracted symptoms in non-hospitalized university students who experienced mild-to-moderate acute illness. Data from COVID-19 positive participants with symptoms ≥28 days (N=22) were compared to those who fully recovered (N=21) and those not diagnosed with COVID-19 (N=58). Our results contradict the perception that this “yet to be defined” post-COVID syndrome predominantly affects middle-aged adults and suggest that exercise intolerance, dyspnea, chest pain, chemosensory impairment, lymphadenopathy, rhinitis, and appetite loss may differentiate post-COVID syndrome from general symptoms of pandemic, age, and academic related stress. These findings are also consistent with previous reports that females are more vulnerable to this post viral syndrome.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de sant&amp;eacute; publique

In this paper, we propose a dynamic model that incorporates individuals' behavior change in social interactions at different stages of the epidemics. We fit our model to the data in Ontario, Canada and calculate the effective reproduction number Rt within each stage. We also investigate the effectiveness of disease intervention strategies. Simulations demonstrate that enlarging the testing capacity and motivating infected individuals to test for an early diagnosis may facilitate mitigating the disease spread in a relatively short time.  Results also indicate a significantly faster decline of confirmed positive cases if individuals practice strict physical distancing even if restricted measures are lifted.

Cancer survivors in routine follow-up would achieve better short-term outcomes. COVID-19 patients with cancer should gain more attention and close monitoring.

Follow-up management strategy for patients undergoing peritoneal dialysis during novel coronavirus pneumonia epidemic

Wang,  Y,  Wang, et al

European review for medical and pharmacological sciences

Healthcare Response | Réponse des soins de santé

The study aimed to explore the best follow-up management strategy for patients undergoing peritoneal dialysis (PD) during the novel coronavirus pneumonia (NCP) epidemic. Since January 2020, among the 580 patients undergoing PD who were followed up in our department and their families, none had NCP infection. The patient follow-up strategy during the epidemic period had a significant positive effect on preventing and controlling the epidemic. Furthermore, during the epidemic period, encouraging patients and caregivers to pay attention to protection at home, avoid going out, strengthen self-management, and other measures were beneficial to the control of kidney disease itself, which is worth promoting.

In the present study, we investigated whether intolerance of uncertainty (IU), a psychological vulnerability factor involved in both OCD and health anxiety, accounts for a portion of the relationship between these symptoms and fear of COVID-19 during the early stages of the outbreak in the Unites States. Results revealed that concern about COVID-19 was moderately and positively correlated with both OCD and health anxiety symptoms, as well as IU. Moreover, regression analyses found that IU partially accounted for the connections between concern about the spread of COVID-19 and OCD and health anxiety symptoms.

The objective of this study was to reconstruct the early phase of the 2020 COVID-19 pandemic in Bavaria from the official case numbers of the Robert Koch Institute in Berlin as well as press and Twitter messages. The initial outbreak could be sufficiently covered using isolation and quarantine measurements, the consecutive early spreading falls into three phases, starting with winter school holidays at the end of February, a number of beer festivals in the following week, and general elections on March, 15. The epidemic started with a few cases during the winter holidays, increased exponentially afterwards including significant more cases by beer festivals and another significant excess of cases following the election that occurred in Bavaria only.

Modelling/ prediction| Modélisation/prédiction Epidemiology| Épidémiologie Public health interventions*| Interventions de sant&amp;eacute; publique

In this study, we apply stochastic optimization to recommend policy triggers governing stages of community mitigation to prevent overwhelming hospital surges and ensure adequate capacity in the unlikely case that they occur. Our data-driven optimization model is built atop a high fidelity SEIR-style (susceptible-exposed-infectious-recovered) simulation model of SARS-CoV-2 transmission. Our findings provide a robust strategy for tracking COVID-19 hospital admissions as an early indicator of hospital surges and enacting staged measures to ensure integrity of the health system, safety of the health workforce, and public confidence.

Epidemiology| Épidémiologie Coronavirology| Coronavirologie

In this study, we classify the genera of COVID-19 and provide brief information about the root of the spread and the transmission from animal (natural host) to humans. We establish a model of fractional-order differential equations to discuss the spread of the infection from the natural host to the intermediate one, and from the intermediate one to the human host. At the same time, we focus on the potential spillover of bat-borne coronaviruses. We consider the local stability of the co-existing critical point of the model by using the Routh–Hurwitz Criteria. Moreover, we analyze the existence and uniqueness of the constructed initial value problem. We focus on the control parameters to decrease the outbreak from pandemic form to the epidemic by using both strong and weak Allee Effect at time t. Furthermore, the discretization process shows that the system undergoes Neimark–Sacker Bifurcation under specific conditions. Finally, we conduct a series of numerical simulations to enhance the theoretical findings.

T cell and antibody functional correlates of severe COVID-19

Clinical data| Données cliniques Immunology | Immunologie

We used multi-parameter flow cytometry and systems serology to comprehensively profile the functions of T cells and antibodies targeting spike, nucleocapsid, and envelope proteins in a convalescent cohort of COVID-19 subjects who were either hospitalized (n=20) or not hospitalized (n=40).  Surprisingly, we found that the magnitude and functional breadth of virus-specific CD4 T cell and antibody responses were consistently higher among hospitalized subjects, particularly those with medical comorbidities. However, an integrated analysis identified more coordination between polyfunctional CD4 T-cells and antibodies targeting the S1 domain of spike among subjects that were not hospitalized. These data reveal a functionally diverse and coordinated response between T cells and antibodies targeting SARS-CoV-2 which is reduced in the presence of comorbid illnesses that are known risk factors for severe COVID-19.

We formulate the task of differentiating viral pneumonia from non-viral pneumonia and healthy controls into a one-class classification-based anomaly detection problem. We therefore propose the confidence-aware anomaly detection (CAAD) model, which consists of a shared feature extractor, an anomaly detection module, and a confidence prediction module. When directly testing on the X-COVID dataset that contains 106 COVID-19 cases and 107 normal controls without any fine-tuning, our model achieves an AUC of 83.61% and sensitivity of 71.70%, which is comparable to the performance of radiologists reported in the literature.

This study compared the anxiety level of the frontline dental staff (FDS) to the general public in Yichang during the coronavirus disease of 2019 (COVID-19) pandemic and examined potential explanatory factors to the differences. In general, FDS were 4.342 (95% CI: 2.427–7.768) times more likely to suffer from anxiety disorders than the general public. The bivariate analysis showed that age, Level Three Protective Measures (PM-3), conflicts with patients and/or colleagues were moderately associated with the anxiety state of FDS. But the knowledge of COVID-19, the treatment to suspected or confirmed cases both had a weak association with the anxiety among FDS.

Arrhythmia in patients with severe coronavirus disease (COVID-19): a meta-analysis

Wen,  W,  Zhang, et al

European review for medical and pharmacological sciences

Review Literature| Revue de littérature

MA:searched PubMed, Embase, Web of Science, and the Cochrane Library for case control studies that were published between January 1 and July 25, 2020. This study showed that the incidence of arrhythmia in patients with severe COVID-19 was greater than that of those with non-severe COVID-19. Patients with severe COVID-19 had a higher risk of arrhythmia complications, which further showed that COVID-19 may be a risk factor for arrhythmia and that the incidence of arrhythmia may increase with the progression of the disease. More importantly, this meta-analysis graded the reliability of evidence for further basic and clinical research into arrhythmia in patients with COVID-19.

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 and activities by collaborators.  Members of the Emerging Sciences group examine and shorten the abstract or 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.

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

Immunology: the study of the immune system and includes serology studies in conjunction with other foci (e.g. epidemiology or diagnostics)

Animal Model: An animal model is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the added risk of harming an actual human.

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

Review Literature:  All 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.

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, 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*.
