Higher nighttime light exposure was associated with adverse changes in cardiac structure and function and increased risks of cardiovascular disease (CVD) events and death. In this UK Biobank population-based study, 11,071 participants with 7-day wrist-worn light measurements and subsequent cardiac MRI were evaluated, with high nighttime light exposure (>3 lux) […]
In two UK cohorts including 977,282 adults, drinking beverages at a “very hot” temperature was associated with more than a threefold higher risk of esophageal squamous cell carcinoma (SCC), while drinking 6 or more hot beverages per day was associated with a 71% higher SCC risk. Over 11–14 years of […]
Regular smoking was associated with a lower risk of Parkinson disease (PD), and among people who never smoked, higher levels of exhaled carbon monoxide (CO) were associated with a lower risk of PD in a broadly dose-dependent manner. This nationwide prospective cohort study included 512,724 adults aged 30–79 years from […]
The recombinant shingles vaccine was associated with a 9% reduction in overall cardiovascular burden over 7 years among adults aged 60 years or older, based on a natural experiment that reduced confounding from existing studies comparing vaccinated and unvaccinated individuals. Researchers compared adults vaccinated immediately before versus immediately after the […]
Waist circumference (WC) and waist-to-hip ratio (WHR) identified important differences in cardiovascular disease (CVD) risk that were not captured by conventional BMI categories, suggesting that central adiposity can reclassify CVD risk across normal weight, overweight, and obesity and provide additional diagnostic and prognostic information. The US Cross-Cohort Collaboration study included […]
Restricting sugar intake during the first 1,000 days from conception was associated with a lower risk of dementia, delayed disease onset by about 2.5–2.9 years, and better brain health in later life. Using the end of UK sugar rationing in September 1953 as a natural experiment, researchers analyzed 64,737 UK […]
Incidental coronary artery calcium (CAC) identified on routine nongated chest CT scans predicts future coronary heart disease (CHD) and cardiovascular disease (CVD) events with prognostic performance comparable to dedicated gated cardiac CT, supporting its incorporation into routine clinical practice for cardiovascular risk assessment. This study included 2,472 participants from the […]
Higher blood levels of the gut microbiome-derived metabolite trimethylamine N-oxide (TMAO) were independently associated with an increased risk of developing abdominal aortic aneurysms (AAAs) and experiencing serious AAA-related events in apparently healthy older adults. Researchers measured plasma TMAO levels in 4,442 community-dwelling adults aged 65 years or older from the […]
Accelerated biological aging was associated with a higher risk of early-onset solid cancers in young adults, particularly lung, gastrointestinal, and uterine cancers, suggesting that biological aging may help explain the rising incidence of cancer in recent generations. In a study of 154,169 young adults from the UK Biobank, systemic biological […]
Men who started testosterone therapy (TT) without evidence of hypogonadism had significantly higher long-term risks of major adverse cardiovascular events (MACE), all-cause mortality, ischaemic stroke, cardiac arrest, and heart failure than men with documented hypogonadism. In this global retrospective real-world study of 358,957 men aged 30–75 years initiating TT, 35.4% […]
