The temporal evolution of SARS-CoV-2 vaccine efficacy and effectiveness (VE) against infection, symptomatic, and severe COVID-19 is incompletely defined. The temporal evolution of VE could be dependent on age, vaccine types, variants of the virus, and geographic region. We aimed to conduct a systematic review and meta-analysis of the duration of VE against SARS-CoV-2 infection, symptomatic COVID-19 and severe COVID-19. MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Coc...

The activity of marine microorganisms depends on community composition, yet, in some oceans, little is known about the environmental and ecological processes that structure their distribution. The objective of this study was to test the effect of geographic distance and environmental parameters on prokaryotic community structure in the Southern Ocean (SO). We described the total (16S rRNA gene) and the active fraction (16S rRNA-based) of surface microbial communities over a ~6.500 km longitudina...

This US Preventive Services Task Force modeling study provides updated estimates of the net balance in benefits and harms of routine use of low-dose aspirin for

Aortic aneurysm (AA) is a global public health concern. However, little is known about the disease burden of AA in China. Following the general analytic strategy used in the Global Burden of Disease Study (GBD) 2019, we analyzed the mortality and years of life lost (YLLs) due to AA, stratified by sex, age, and province-level region in China from 1990 to 2019. The temporal trend of AA burden in China was analyzed and the main attributable risk factors for AA in China were also explored. In China,...

Food security and livelihoods among smallholder farmers in sub-Saharan Africa are often constrained by limited farm resource endowment. It can be difficult to improve resource endowment given barriers such as low land availability and the unaffordability of agricultural inputs, so here we ask whether farmers can gain a better return on their resources through optimising their farm strategy in terms of the composition and/or diversity of crop and livestock species raised. Our survey of 1133 small...

Citywide Integrated Aedes aegypti Mosquito Surveillance as Early Warning System for Arbovirus Transmission, Brazil - The Maravi Post

In this article, statistician Bruno Wiesend reports on a scientific controversy about a study on the "Influence of intelligence and practice on the development of skills". The author considers the results of the study to be wrong due to methodological errors. | Photo: Pixabay

We review the most important statistical ideas of the past half century, which we categorize as: counterfactual causal inference, bootstrapping and simulation-based inference, overparameterized mod...

Although global surveillance of antimicrobial resistance (AMR) is considered key in the containment of AMR, data from low- and middle-income countries, especially from sub-Saharan Africa, are scarce. This study describes epidemiology of bloodstream infections and antimicrobial resistance rates in a secondary care hospital in Benin. Blood cultures were sampled, according to predefined indications, in BacT/ALERT FA Plus and PF Plus (bioMérieux, Marcy-l’Etoile, France) blood culture bott...
