AI Article Synopsis
- Temporary maintenance workers in petrochemical plants in Korea are exposed to carcinogens like benzene, raising concerns about cancer risk.
- A study analyzed data from 14,698 male workers between 2002-2007, linking cancer and mortality rates to national registries.
- The results indicated higher rates of oral and pharyngeal cancers in these workers, suggesting a possible link, and recommended further research with extended follow-up and exposure assessments.
Article Abstract
Background: Petrochemical plant maintenance workers are exposed to various carcinogens such as benzene and metal fumes. In Korea, maintenance operations in petrochemical plants are typically performed by temporary employees hired as contract workers.
Objectives: The purpose of this retrospective study was to evaluate cancer risk in temporary maintenance workers in a refinery/petrochemical complex in Korea.
Methods: Subjects consisted of 14 698 male workers registered in a regional petrochemical plant maintenance workers union during 2002-2007. Cancer mortality and incidence were identified by linking with the nationwide death and cancer registries during 2002-2007 and 2002-2005, respectively. Standardized mortality ratios (SMRs) and standardized incidence ratios (SIRs) were calculated for each cancer.
Results: Increased SMR 3·61 (six cases, 95% CI: 1·32-7·87) and SIR 3·18 (five cases, 95% CI: 1·03-7·42) were observed in oral and pharyngeal cancers.
Conclusion: Our findings may suggest a potential association between oral and pharyngeal cancers and temporary maintenance jobs in the petrochemical industry. Future studies should include a longer follow-up period and a quantitative exposure assessment.

Background: Cardiometabolic multimorbidity (CMM), characterized by the coexistence of diabetes, hypertension, and cardiovascular disease, poses a major health challenge in India, particularly in rural areas with limited healthcare resources. Lifestyle interventions can manage cardiometabolic risk factors, yet adherence remains suboptimal. Mobile health (mHealth) interventions offer a scalable approach for managing CMM by promoting behaviour change and medication adherence.

Introduction: Health literacy is considered a determinant of several health-related behaviors and outcomes. Health literacy can be seen as a particularly relevant resource for health maintenance and promotion for young adults at the beginning of their challenging vocational training in nursing. However, the underlying mechanisms and the roles of other influencing factors such as self-efficacy remain unclear and need to be understood to successfully tailor interventions.

Telomere attrition is a hallmark of biological aging, contributing to cellular replicative senescence. However, few studies have examined the determinants of telomere attrition in vivo in humans. Mitochondrial Health Index (MHI), a composite marker integrating mitochondrial energy-transformation capacity and content, may be one important mediator of telomere attrition, as it could impact telomerase activity, a direct regulator of telomere maintenance.
