AbstractMasking was the single most common non-pharmaceutical intervention in the course of the coronavirus disease 2019 (COVID-19) pandemic. Most countries have implemented recommendations or mandates regarding the use of masks in public spaces. The aim of this short study was to analyse the correlation between mask usage against morbidity and mortality rates in the 2020-2021… Continue reading Correlation Between Mask Compliance and COVID-19 Outcomes in Europe

Hypertension after anti-COVID-19 vaccination
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapidly spread across the world, killing more than 4 million individuals globally, with 240 million individuals being confirmed by laboratory tests. Among different therapeutic strategies to prevent SARS-CoV-2 infection, vaccines are the most promising approach for curbing the pandemic. They elicit an immune neutralizing response and thus offer… Continue reading Hypertension after anti-COVID-19 vaccination
Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
Risk of SARS-CoV-2 reinfection among unvaccinated people with prior COVID-19 is a subject of debate.1,2 We performed a survival analysis in a large US population to assess the degree and duration of protection associated with natural immunity in unvaccinated individuals MethodsThis cohort study used data from patients tested for SARS-CoV-2 at 1300 sites of care… Continue reading Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
Background & AimsAutoimmune hepatitis episodes have been described following SARS-CoV-2 infection and vaccination but their pathophysiology remains unclear. Here, we report the case of a 52-year-old male, presenting with bimodal episodes of acute hepatitis, each occurring 2-3 weeks after BNT162b2 mRNA vaccination and sought to identify the underlying immune correlates. The patient received first oral… Continue reading SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
Background: Waning of protection against infection with SARS-CoV-2 conferred by 2 doses of the BNT162b2 vaccine begins shortly after inoculation and becomes substantial within four months. With that, the impact of prior infection on incident SARS-CoV-2 reinfection is unclear. Therefore, we examined the long-term protection of naturally acquired immunity (protection conferred by previous infection) compared… Continue reading SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
BackgroundAt the beginning of the SARS-CoV-2 pandemic we stated that,given the new virus and the little-known disease it caused, in theabsence of Evidence-Based Medicine indications, patients shouldhave been treated with drugs already available, useful to counteractthe pathophysiology of the COVID-19 [1]. Recent literature hasconfirmed that this could be a successful approach, demonstratingthat an early treatment… Continue reading COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
Efficacy and Safety of Vitamin D Supplementation to Prevent COVID-19 in Frontline Healthcare Workers. A Randomized Clinical Trial
Background. Associations between vitamin D (VD) deficiency and the risk of SARS-CoV-2 infection have been documented in cross-sectional population studies. Intervention studies in patients with moderate to severe COVID-19 have failed to consistently document a beneficial effect. Objective. To determine the efficacy and safety of VD-supplementation in the prevention of SARS-CoV-2 infection in highly exposed… Continue reading Efficacy and Safety of Vitamin D Supplementation to Prevent COVID-19 in Frontline Healthcare Workers. A Randomized Clinical Trial
Psychological Distress Before and During the COVID-19 Pandemic Among Adults in the United Kingdom Based on Coordinated Analyses of 11 Longitudinal Studies
How population mental health has evolved across the COVID-19 pandemic under varied lockdown measures is poorly understood, and the consequences for health inequalities are unclear. Objective To investigate changes in mental health and sociodemographic inequalities from before and across the first year of the COVID-19 pandemic in 11 longitudinal studies. Design, Setting, and Participants This… Continue reading Psychological Distress Before and During the COVID-19 Pandemic Among Adults in the United Kingdom Based on Coordinated Analyses of 11 Longitudinal Studies
Estimating disease severity of Omicron and Delta SARS-CoV-2 infections
The Omicron variant of SARS-CoV-2 has been reported to cause milder disease in adults but lead to increased hospital admissions in children. How can we compare disease severity in Omicron and Delta infections, and how should differences be interpreted? Measuring COVID-19 disease severity in a population has been important for understanding the public health impact… Continue reading Estimating disease severity of Omicron and Delta SARS-CoV-2 infections
