1. Retrospective analysis of hospital records showed decreased hospital admission rates for non-COVID-19 diseases in Denmark since the first lockdown. 2. Mortality rates were also shown to be higher for non-COVID-19 diseases, including respiratory diseases, cancer, pneumonia, and sepsis. Evidence Rating Level: 2 (Good) Study Rundown: The COVID-19 pandemic has put a...
1. This cross-sectional study found that events leading to informal social gatherings, such as birthdays among households, were associated with increased rates of diagnosed COVID-19 infection. 2. COVID-19 diagnoses per 10,000 individuals were higher among child birthdays than adult birthdays, further highlighting informal social gatherings as a potential important source...
1. Therapeutic anticoagulation with rivaroxaban or enoxaparin did not improve clinical outcomes and increased bleeding compared with prophylactic anticoagulation. 2. Net clinical benefit composite of death, thrombotic events, and major or clinically relevant non-major bleeding was not significantly different between groups. Evidence Rating Level: 1 (Excellent) Study Rundown: COVID-19 is associated with...
1. In this epidemiological cohort study based out of Valencia, Spain, the neighborhood where the hospital and COVID-19 testing facility was situated correlated with a high number of total infectious connections and was potentially a major contributor to local spread. 2. These findings suggest that a more selective and strategic...
1. A similar proportion of patients died within 28 days of randomization in both groups (high-titre convalescent plasma vs. usual care). 2. Allocation to convalescent plasma had no significant effect on the proportion of patients discharged from hospital within 28 days. Evidence Rating Level: 1 (Excellent) Study Rundown: Convalescent plasma is a...
1. In-hospital mortality within 30 days of admission for COVID-19 was 48% (vs. global mortality 31.5%). 2. Increased age, underlying comorbidities and delay in admission were associated with an increased mortality rate among African patients. Evidence Rating Level: 2 (Good) Study Rundown: The COVID-19 pandemic has exposed long-standing inequities in healthcare. Critically...
1. There was a vaccine efficacy of 97.2% against symptomatic COVID-19 infection in individuals at least 7 days after their second vaccine dose. 2. Substantial and consistent declines in COVID-19 incidence corresponded to greater vaccine coverage. Evidence Rating Level: 2 (Good) Study Rundown: Beyond clinical trials, there is growing evidence of the...
1. Participants identifying as South Asian or Black were more likely to test positive for COVID-19 infection, be hospitalized for COVID-related symptoms, and be admitted to the intensive care unit compared with the White population. 2. In the second wave, the relative rates of COVID-related hospitalization, ICU admission, and death...
1. Compared to usual care, fewer patients in the tocilizumab group died within 28 days of randomization. 2. Patients allocated tocilizumab were more likely to be discharged from the hospital within 28 days. Evidence Rating Level: 1 (Excellent) Study Rundown: Hypoxic respiratory failure in patients with COVID-19 is associated with systemic inflammation, alveolar damage,...
1. Vaccinated individuals reported fewer SARS-CoV-2 infections and a lesser proportion of cases were symptomatic compared to the unvaccinated cohort. 2. BNT162b2 mRNA vaccine showed an effectiveness of 70% 21 days after a single dose. Evidence Rating Level: 2 (Good)  Study Rundown: The BNT162b2 mRNA (Pfizer-BioNTech) and ChAdOx1 nCoV-19 adenoviral (Oxford-AstraZeneca) COVID-19...
