We examined characteristics and predictors of hospitalization and death in a nationwide cohort of all Danish individuals tested for severe acute respiratory syndrome coronavirus 2.

Detection of SARS-COV N2 Gene: Very low amounts of viral RNA or false positive?

In 17 out of 36 positive patients, very low viral RNA copies were suspected since positivity was detected at high Ct. We confirmed positivity for patients who showed both E and N genes detected and for patients with only N detected but with Ct <39

Combined throat/nasal swab sampling for SARS-CoV-2 is equivalent to nasopharyngeal sampling

We compared the combined throat/nasal sampling with. nasopharyngeal sampling for detection of SARS-CoV-2 in healthcare workers suspected of. COVID-19. 80 healthcare workers tested negative with both sampling methods, and 25 healthcare workers (23.4%) tested positive with both methods.

Performance characteristics of five immunoassays for SARS-CoV-2: a head-to-head benchmark comparison

Four commercial, widely available assays and a scalable 384-well ELISA can be used for SARS-CoV-2 serological testing. All assays achieved a sensitivity of at least 98% with thresholds optimised to achieve a specificity of 98% on samples taken 30 days or more post symptom onset.

COVID-19 in a cohort of pregnant women and their descendants, the MOACC-19 study

The Mother and Child COVID-19 study is a cohort recruiting pregnant women and their children in Cantabria, North of Spain. The aim is to ascertain consequences of SARS-CoV-2 infection on pregnant women. This article reports the cohort profile and preliminary results as recruitment is still open.

Echocardiographic Features of Cardiac Injury Related to COVID-19 and Their Prognostic Value: A Systematic Review

Echocardiographic features of cardiac injury related to the novel coronavirus disease 2019 (COVID-19) and their prognostic value are scattered in the different literature. Therefore, the aim of this study was to investigate the echocardiographic features of cardiac injury related to COVID-19 and their prognostic value. RV dilatation and dysfunction may be the most prominent echocardiographic abnormality in symptomatic patients with COVID-19, especially in those with more severe or deteriorating

The role of Chinese medicine in COVID-19 pneumonia: A systematic review and meta-analysis

Chinese medicine has been used to treat Novel Coronavirus 2019 (COVID-19) pneumonia in China. A meta-analysis was conducted to evaluate the clinical efficacy and safety of CM in the treatment of the disease. The meta-analysis exhibited in comparison to conventional treatment, CM combined with conventional treatment significantly improved clinical efficacy. According to the allocated data, CM has demonstrated clinical efficacy and safety on COVID-19 pneumonia.

Warmer weather unlikely to reduce the COVID-19 transmission: An ecological study in 202 locations in 8 countries

To examine the association between meteorological factors and transmission capacity of COVID-19. Cases of COVID-19 have been confirmed in 202 locations in 8 countries. We examined the possible association between meteorological conditions. Meteorological conditions did not have statistically significant associations with the R0 of COVID-19. Warmer weather alone seems unlikely to reduce the CO VID-19 transmission.
