This systematic review and meta-analysis are designed to determine whether there is empiricalevidence to support the belief that “lockdowns” reduce COVID-19 mortality. Lockdowns aredefined as the imposition of at least one compulsory, non-pharmaceutical intervention (NPI).NPIs are any government mandate that directly restrict peoples’ possibilities, such as policies thatlimit internal movement, close schools and businesses, and… Continue reading A LITERATURE REVIEW AND META-ANALYSISOF THE EFFECTS OF LOCKDOWNS ONCOVID-19 MORTALITY
Myocarditis Cases Reported After mRNA-Based COVID-19 Vaccination in the US From December 2020 to August 2021
Importance Vaccination against COVID-19 provides clear public health benefits, but vaccination also carries potential risks. The risks and outcomes of myocarditis after COVID-19 vaccination are unclear. Objective to describe reports of myocarditis and the reporting rates after mRNA-based COVID-19 vaccination in the US. Design, Setting, and Participants Descriptive study of reports of myocarditis to the… Continue reading Myocarditis Cases Reported After mRNA-Based COVID-19 Vaccination in the US From December 2020 to August 2021
Perceived Physical Fatigability Predicts All-Cause Mortality in Older Adults
BackgroundPerceived physical fatigability is highly prevalent in older adults and associated with mobility decline and other health consequences. We examined the prognostic value of perceived physical fatigability as an independent predictor of risk of death among older adults. MethodsParticipants (N = 2 906), mean age 73.5 [SD, 10.4] years, 54.2% women, 99.7% white enrolled in… Continue reading Perceived Physical Fatigability Predicts All-Cause Mortality in Older Adults
Be Alert to the Risk of Adverse Cardiovascular Events after COVID-19 Vaccination
AbstractWith the global popularization of vaccination against coronavirus disease 2019 (COVID-19), the reports of cases of vaccine-related adverse events are increasing gradually. The most common events are local pain at the injection site and atypical symptoms, such as fever, headache, myalgia, and general discomfort. However, a few people might develop serious cardiovascular complications, such as… Continue reading Be Alert to the Risk of Adverse Cardiovascular Events after COVID-19 Vaccination
Neuroticism, Worry, and Cardiometabolic Risk Trajectories: Findings From a 40‐Year Study of Men
Anxiety is linked to elevated risk of cardiometabolic disease onset, but the underlying mechanisms remain unclear. We examined the prospective association of 2 anxiety facets, neuroticism and worry, with cardiometabolic risk (CMR) trajectories for 4 decades. Methods and ResultsThe sample comprised 1561 men from an ongoing adult male cohort. In 1975, healthy men (mean age,… Continue reading Neuroticism, Worry, and Cardiometabolic Risk Trajectories: Findings From a 40‐Year Study of Men
Rapid emergence of SARS-CoV-2 Omicron variant is associated with an infection advantage over Delta in vaccinated persons
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants continues to shape the coronavirus disease 2019 (Covid-19) pandemic. The detection and rapid spread of the SARS-CoV-2 Omicron variant (lineage B.1.1.529) in Botswana and South Africa became a global concern because it contained 15 mutations in the spike protein immunogenic receptor binding domain and… Continue reading Rapid emergence of SARS-CoV-2 Omicron variant is associated with an infection advantage over Delta in vaccinated persons
The Lancet: COVID-19 pandemic led to stark rise in depressive and anxiety disorders globally in 2020, with women and younger people most affected
First global estimates of impact of the COVID-19 pandemic on mental health in 2020 suggests additional 53 million cases of major depressive disorder and 76 million cases of anxiety disorders were due to the pandemic.Women and younger people were the most affected by major depressive disorder and anxiety disorders in 2020.Countries hit hardest by the… Continue reading The Lancet: COVID-19 pandemic led to stark rise in depressive and anxiety disorders globally in 2020, with women and younger people most affected
Do COVID-19 RNA-based vaccines put at risk of immune-mediated diseases? In reply to “potential antigenic cross-reactivity between SARS-CoV-2 and human tissue with a possible link to an increase in autoimmune diseases”
To the Editor,I read with great interest the article by Vojdani et al. [1], concerning the hypothesis of a molecular mimicry mechanism between the nucleoprotein/spike protein of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and self-antigens. Viruses are notoriously involved in the pathogenesis of autoimmune diseases [2], and the authors reasonably conclude that such a… Continue reading Do COVID-19 RNA-based vaccines put at risk of immune-mediated diseases? In reply to “potential antigenic cross-reactivity between SARS-CoV-2 and human tissue with a possible link to an increase in autoimmune diseases”
Transmissibility of SARS-CoV-2 among fully vaccinated individuals
Vaccine effectiveness studies have conclusively demonstrated the benefit of COVID-19 vaccines in reducing individual symptomatic and severe disease, resulting in reduced hospitalisations and intensive care unit admissions.1 However, the impact of vaccination on transmissibility of SARS-CoV-2 needs to be elucidated. A prospective cohort study in the UK by Anika Singanayagam and colleagues2 regarding community transmission… Continue reading Transmissibility of SARS-CoV-2 among fully vaccinated individuals
