Published: March 2025

During the school year, radon (222Rn) was continuously measured with passive detectors in all public schools in Montenegro-345 primary and 47 secondary schools. Measurements were taken in all ground-floor classrooms and offices (2336 rooms in total), as well as in 182 first-floor rooms across 91 schools. On the first floor, the arithmetic mean (AM) of radon concentrations was 100 Bq/m3, and the median (MED) was 65 Bq/m3, with only five schools having rooms where radon levels exceeded 300 Bq/m3. On the ground floor of all 392 schools, the AM was 276 Bq/m3, and the MED was 146 Bq/m3. In 188 schools, some rooms had radon levels above 300 Bq/m3, and in 43 schools, certain rooms exceeded 1000 Bq/m3. An assessment of the effective annual doses from radon inhalation for pupils was also conducted. On average, the dose was 0.66 mSv per school year, although in some classrooms it reached up to 11 mSv.

Background: Studying the spatial pattern of out-of-hospital cardiac arrest (OHCA) and its environmental impactors is crucial for both providing timely medical assistance and implementing preventative measures. Existing researches have mainly focused on natural and sociodemographic environments, usually at a macro- or meso-scale, while giving less attention to understanding the association between environment and OHCA risk from the perspective of daily-life contexts.

Methods: In this study, we utilized 1843 eligible OHCA cases from core districts of Beijing in 2020 and employed modified Besag-York-Mollié (BYM2) Bayesian models to investigate the association between living environment (consisting of food environment, physical activity environment, healthcare environment and leisure environment) and adult OHCA risk, as well as its age disparities, at a 1 × 1 km cell resolution.

Introduction: Limited access to resources and stereotypes about orthopaedic surgeons may contribute to the low percentage of women and people of underrepresented in medicine (URiM) backgrounds in orthopaedic surgery. Several organizations have created resources to address these barriers, but medical students are unlikely to be exposed to the initiatives through traditional curricula. The purpose of this study was to (1) evaluate the ability of a 1-day virtual Diversity, Equity, Inclusion, and Accessibility (DEIA) summit to effectively reach URiM medical students, (2) increase medical students' knowledge of DEIA resources, and (3) augment the perception of diverse backgrounds in orthopaedic surgery.

Smoke-free homes (SFHs) reduce secondhand smoke exposure (SHSe), which is particularly crucial where smoking prevalence is high and public smoke-free policies are nascent, as in some low- and middle-income countries (LMICs). This study examined perspectives regarding SFHs, including barriers and facilitators, among adults in Armenia, a LMIC with high male smoking prevalence and recently-implemented smoke-free policies. In February-March 2024, focus groups were conducted with adults reporting smoking and non-smoking, separately, in two Armenian communities ( = 39; = 41.
