Associations between multidimensional sleep measures and domain-specific cognitive function across repeated observations in adults aged 55 years and older

3 days 18 hours ago
Sleep is increasingly recognised as a potentially modifiable factor in cognitive ageing, but evidence is often limited by cross-sectional designs, single sleep measures and global cognitive outcomes. This study examined whether multiple sleep characteristics (device-based and self-report) were associated with domain-specific cognitive function across repeated observations in community-dwelling adults aged 55 years and older. Adults aged ≥ 55 years were assessed at three time points over 2 years...

Duration of smoking cessation and DNA methylation aging clocks among US adults: potential reversibility of smoking-induced biological aging

3 days 18 hours ago
Tobacco smoking is a critical modifiable risk factor for age-related diseases and mortality. Although smoking cessation is known to improve health outcomes, whether smoking-induced biological aging is reversible upon cessation remains unclear. We investigated the associations of smoking status and cessation duration with epigenetic age acceleration (EAA) using multi-generational DNA methylation clocks. We analyzed data from 1,911 adults aged 50-84 years in the National Health and Nutrition...

Work stress and healthy aging: A conceptual framework for the Semmelweis study and the Semmelweis-EUniWell workplace health promotion model program

3 days 18 hours ago
Chronic occupational stress is increasingly recognized as a modifiable accelerator of biological aging, yet it remains underappreciated as a target of geroscience-informed public health intervention. This review reframes workplace stress as a life-course determinant of aging trajectories and introduces a translational framework that positions occupational environments as platforms for promoting healthy aging. Drawing on insights from the Semmelweis Study, a large longitudinal occupational...

Nearly 10,000 patients reveal what works best for knee arthritis pain relief

4 days ago
A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while water-based therapy was especially effective for pain and regular exercise consistently improved both pain and physical function. More high-tech approaches, including ultrasound, generally performed worse.
