From indoors to outdoors: Impact of waste anesthetic gases on occupationally exposed professionals and related environmental hazards - A narrative review and update.

Waste anesthetic gases (WAGs) are trace-concentration inhaled anesthetics that exist worldwide because they are released into the ambient air of operating rooms (ORs) and post-anesthesia care units. WAGs cause indoor contamination, especially in ORs lacking proper scavenging systems, and occupational exposure, while promoting climate change through greenhouse gas/ozone-depleting effects. Despite these controversial features, WAGs continue to pose occupational health hazards.

A New Natural Language Processing-Inspired Methodology (Detection, Initial Characterization, and Semantic Characterization) to Investigate Temporal Shifts (Drifts) in Health Care Data: Quantitative Study.

Background: Proper analysis and interpretation of health care data can significantly improve patient outcomes by enhancing services and revealing the impacts of new technologies and treatments. Understanding the substantial impact of temporal shifts in these data is crucial. For example, COVID-19 vaccination initially lowered the mean age of at-risk patients and later changed the characteristics of those who died.

Comprehensive statistical analysis reveals significant benefits of COVID-19 vaccination in hospitalized patients: propensity score, covariate adjustment, and feature importance by permutation.

Background: COVID-19 vaccines effectively prevent infection and hospitalization. However, few population-based studies have compared the clinical characteristics and outcomes of patients hospitalized for COVID-19 using advanced statistical methods. Our objective is to address this evidence gap by comparing vaccinated and unvaccinated patients hospitalized for COVID-19.
