Why one gut microbe is attracting attention in heart failure research

Researchers found that chronic systolic heart failure caused by nonischemic cardiomyopathy was associated with reduced gut microbial diversity, depletion of Bifidobacterium, and lower microbial short-chain fatty acid production potential. Higher Bifidobacterium abundance and higher circulating indole-3-propionic acid levels were associated with milder disease and clinical improvement, although the findings do not establish causality.

AHA calls for lifelong brain health strategy to prevent cognitive decline

The AHA scientific statement calls for a life-course approach to brain health that integrates cognitive, emotional, behavioral, vascular, environmental, inflammatory, sleep, microbiome, and social factors. It highlights how early-life exposures, mental health, pollution, chronic inflammation, poor sleep, gut dysbiosis, and socioeconomic adversity may shape brain resilience and later-life cognitive decline.
