Risk of adverse cardiovascular events based on common genetic variants in 8-year follow-up of the LIPIDOGEN2015 population using the polygenic risk score (PRS): study design and methodology.

Introduction: Classical risk factors such as hypertension, hypercholesterolemia, pre-diabetes, diabetes and obesity can predict adverse cardiovascular events, but they are less prognostic in patients aged < 60 years. Polygenic risk scores (PRS) can be effective in predicting adverse coronary events in younger and middle-aged patients. Our main aim is to assess the utility of a new PRS created for the Polish population in predicting mortality during an 8-year follow-up in the nationwide LIPIDOGEN2015 population.

Sewage sludge fertilization affects microbial community structure and its resistome in agricultural soils.

Global sewage sludge production is rapidly increasing, and its safe disposal is becoming an increasingly serious issue. One of the main methods of municipal sewage sludge management is based on its agricultural use. The wastewater and sewage sludge contain numerous antibiotic resistance genes (ARGs), and its microbiome differs significantly from the soil microbial community.

α-Hemolysin from Staphylococcus aureus Changes the Epigenetic Landscape of Th17 Cells.

The human body harbors a substantial population of bacteria, which may outnumber host cells. Thus, there are multiple interactions between both cell types. Given the common presence of Staphylococcus aureus in the human body and the role of Th17 cells in controlling this pathogen on mucous membranes, we sought to investigate the effect of α-hemolysin, which is produced by this bacterium, on differentiating Th17 cells.

The whole genome sequence of Polish vaccine strain BCG Moreau.

Unlabelled: Currently, tuberculosis immunoprophylaxis is based solely on Bacillus Calmette-Guérin (BCG) vaccination, and some of the new potential tuberculosis vaccines are based on the BCG genome. Therefore, it is reasonable to analyze the genomes of individual BCG substrains. The aim of this study was the genetic characterization of the BCG-Moreau Polish (PL) strain used for the production of the BCG vaccine in Poland since 1955.

Stopover habitat selection drives variation in the gut microbiome composition and pathogen acquisition by migrating shorebirds.

Long-distance host movements play a major regulatory role in shaping microbial communities of their digestive tract. Here, we studied gut microbiota composition during seasonal migration in five shorebird species (Charadrii) that use different migratory (stopover) habitats. Our analyses revealed significant interspecific variation in both composition and diversity of gut microbiome, but the effect of host identity was weak.
