The Petri dish under the ice: permafrost pathogens and their impact on global healthcare and antibiotic resistance.

Background: A shallow active layer of soil above the permafrost thaws during the summer months which promotes microbial growth and releases previously confined pathogens which result in bacterial epidemics in circumpolar regions. Furthermore, these permafrost sources harbor several antibiotic resistance genes (ARGs) which may disseminate and pose a challenge for pharmacologists worldwide.

Aims: The authors examined the potential association between climate change-induced permafrost thawing, and the resulting release of antibiotic-resistant pathogens, as well as the potential impact this can have on global healthcare systems in the long run.

Improved Early Outcomes With Off-Pump Coronary Artery Bypass Grafting in Patients With Left Ventricular Dysfunction: A Systematic Review and Meta-Analysis.

The ongoing debate surrounding coronary artery bypass grafting (CABG) with or without cardiopulmonary bypass persists, particularly in individuals with left ventricular dysfunction. The objective of this study was to evaluate the safety and efficacy of these 2 strategies through a comprehensive meta-analysis of existing studies. A systematic search of PubMed, EMBASE, Web of Science, and the Cochrane Central Registry was conducted from inception to July 2023.
