Medical radiation exposures have been reduced significantly with modern equipment and protection measures. Biomonitoring of medical personnel can provide information concerning possible effects of radiation exposure. However, chromosome aberration (CA) analysis is now recommended only when the estimated effective dose is 200 mSv or higher. In this retrospective study in Bosnia and Herzegovina, we have measured the cytogenetic status of medical workers and healthy volunteers (controls). Peripheral blood samples from 66 medical workers exposed to low-dose ionising radiation and 89 non-exposed volunteers were collected for chromosome aberrations (CA) analysis and the cytokinesis-block micronucleus (CBMN) assay. Higher rates of chromatid and chromosome breaks, acentric fragments, double minutes, micronuclei, and micronucleated binuclear cells were observed in the control group, while the rate of nucleoplasmic bridges was higher in the medical workers group.

Mutagenicity, DNA Repair Gene Polymorphism, and Differentially Expressed Plasma Protein Fractions among Textile Dyeing Workers.
J Occup Environ Med
November 2024
Industrial Medicine and Occupational Health, Public Health and Community Medicine Department, Faculty of Medicine, Mansoura University, Mansoura, Egypt.
Objectives: This study aimed to assess mutagenicity biomarkers among Egyptian textile dyeing workers, their alteration with gene polymorphism, and the changes in plasma proteins' expression.
Methods: Using a detailed questionnaire, a comparative cross-sectional study was conducted on 212 workers (106 textile dyeing exposed group and 106 control group). CBMN-Cyt assay, ERCC2 gene polymorphism, and plasma protein fractions were analyzed in workers' blood samples.

All the authors affiliated to Yiling People's Hospital of Yichang City, 32# Donghu st., Yichang, Hubei, China, 443000.
Objective: This study evaluates the utility of serum s-αKlotho levels as a quantifiable biomarker for overwork.
Methods: Frontline medical workers aged 20-55 from Yiling People's Hospital of Yichang were recruited. Criteria included non-smokers, non-heavy drinkers, no chronic medication use, and no acute illnesses recently.
Sustainability of an evidence-based intervention supporting transition to independent care for youth living with HIV in Kenya.
PLOS Glob Public Health

Department of Global Health, University of Washington, Seattle, Washington, United States of America.
Integrating and sustaining evidence-based interventions (EBIs) in routine care is crucial to improving HIV treatment outcomes among youth living with HIV (YLH). However, EBIs are often not sustained post clinical trial. An Adolescent Transition Package (ATP) delivered by health care workers (HCWs) and tested in Kenya in 2021 significantly improved YLH readiness to transition to independent care.

PLoS One
January 2025
Division of General Internal Medicine, Massachusetts General Hospital, Boston, Massachusetts, United States of America.
Objective: Identify the most important sociodemographic and behavioral factors related to the diet of low-income adults with hypertension in order to guide the development of a community health worker (CHW) healthy eating intervention for low-income populations with hypertension.
Design: In this cross-sectional analysis, dietary recalls were used to assess Healthy Eating Index-2020 (HEI-2020) total (range: 0 to 100 [best diet quality]) and component scores and sodium intake. Self-reported sociodemographic and behavioral data were entered into a Least Absolute Shrinkage and Selection Operator (LASSO) regression model to determine the relative importance of factors related to diet quality.
