DNA methylation clocks, which measure biological age by analyzing age-related DNA methylation patterns, offer powerful biomarkers of aging. But as a recent preprint highlights, current models underperform in diverse populations. The next generation of clocks must prioritize equity to avoid reinforcing disparities in precision aging and disease risk prediction.

This study aims to investigate the predictive value of combined phenotypic age and phenotypic age acceleration (PhenoAgeAccel) for benign prostatic hyperplasia (BPH) and develop a machine learning-based risk prediction model to inform precision prevention and clinical management strategies. The study analyzed data from 784 male participants in the US National Health and Nutrition Examination Survey (NHANES, 2001-2008). Phenotypic age was derived from chronological age and nine serum biomarkers.

Glial fibrillary acidic protein (GFAP) is an astrocytic marker that can be assessed in blood using single molecule array technology. Recent studies suggest that individuals with posttraumatic stress disorder (PTSD) have suppressed circulating levels of this CNS biomarker. This study examined the hypothesis that PTSD and plasma GFAP levels share common genetic and epigenetic pathways.

Low-grade non-muscle invasive bladder cancer is a specific category of bladder cancer with a favourable prognosis; however, its management presents several challenges. The risk of stage progression is very low, but approximately half of patients will experience recurrence within the first 5 years after diagnosis. This high propensity for recurrence, coupled with the threat of progression, mandates ongoing surveillance.

Background: Immune dysregulation and metabolic disturbances contribute to cognitive decline in aging populations. The neutrophil-to-HDL cholesterol ratio (NHR), an emerging immunometabolic biomarker, reflects systemic inflammation and vascular dysfunction. However, its role in predicting cognitive impairment in older adults remains unclear.
