Older adults with established cardiovascular diseases (CVD) are at elevated risk of heart failure (HF). Frailty, a hallmark of multi-system aging, may contribute to HF development through inflammation. However, population-based evidence remains scarce. Leveraging data from 49,530 CVD patients in the UK Biobank, frailty was measured by five components: weight loss, exhaustion, low physical activity, slow walking speed, and low grip strength. We employed Cox regression models to assess the...

CONCLUSIONS: The intake of dietary live microbes is nonlinearly associated with accelerated biological age. IR partially mediated the relationship.

The second Biomarkers of Aging Symposium, jointly hosted by the National Institute on Aging (NIA) Intramural Research Program and the Biomarkers of Aging Consortium (BAC) on September 12, 2024, in Baltimore, MD, convened leading researchers, clinicians, and stakeholders in the aging field to share new developments and discuss roadmaps to advance biomarkers of aging. This meeting report summarizes the highlights of this symposium and underscores the urgent need to understand longitudinal,...

Adult hippocampal neurogenesis-the generation of new neurons in the adult brain-declines with age, contributing to cognitive deficits in aging. While the majority of mammalian studies on neurogenesis have utilized inbred mouse strains, these models do not fully capture the genetic diversity of humans, limiting the translational relevance of their findings. The Diversity Outbred (DO) mouse model, a genetically heterogeneous population, provides a promising alternative to traditional inbred...

Prediabetes, characterized by impaired fasting glucose and/or glucose tolerance, is associated with organ damage, increased mortality, and accelerated aging, even before diabetes onset. Severe short-term energy restriction while maintaining essential nutrient intake is among the most effective strategies for weight loss, metabolic health improvement, and delaying type 2 diabetes progression. Extracellular vesicles contribute to these metabolic benefits; however, the impact of...
