Association of T-EAT-10 and NUFFE-TR scores with a history of aspiration pneumonia in nursing home residents: a cross-sectional study

1 month 2 weeks ago
CONCLUSIONS: The T-EAT-10 is a practical and highly effective screening tool for identifying aspiration pneumonia risk in institutionalized elderly populations. A clinical threshold of >12 is recommended for identifying high-risk residents, which is substantially higher than the standard dysphagia screening cut-off. Systematic screening using T-EAT-10 and NUFFE-TR should be integrated into routine geriatric care in nursing homes to improve preventive strategies.

Bcl11a orchestrates multilineage integrity in aging hematopoiesis by regulating multipotent progenitor fate decisions

1 month 2 weeks ago
Aging hematopoiesis exhibits progressive myeloid skewing and impaired lymphopoiesis, driving age-related blood disorders. We show that multipotent progenitors (MPPs) mediate this lineage imbalance. Aging expands myeloid-biased MPP3 cells while functionally compromising MPP4 lymphoid potential, collectively skewing hematopoietic output toward the myeloid lineage. We identify Bcl11a as a dosage-sensitive regulator of MPP fate: Bcl11a suppresses Fer to restrain premature myeloid differentiation in...

Stroke burden and associated predictors in Ghana: a Bayesian analysis of the WHO study on global ageing and adult health

1 month 2 weeks ago
CONCLUSION: Public health strategies should emphasize physical activity, healthy diets, weight control, and improved management of chronic diseases. These efforts align with the sustainable development goal 3 (SDG 3); Good Health and Well-being, particularly Target 3.4, which aims to reduce premature mortality from non-communicable diseases through prevention and treatment by 2030.

Gut Metabolism Links Precision Nutrition, Exercise, and Healthspan in Drosophila melanogaster

1 month 2 weeks ago
Longevity-promoting interventions commonly entail functional trade-offs, raising the unresolved question of whether lifespan extension necessarily compromises physiological performance. Here, utilizing a chemically defined diet (CDD) in Drosophila melanogaster, we systematically evaluated a multimodal intervention combining methionine restriction (MR), taurine supplementation (Tau), and moderate exercise. This combinatorial approach additively extended lifespan, preserved reproductive capacity,...

Scientists discover a protein that protects the brain from Alzheimer’s damage

1 month 2 weeks ago
A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible drug target that could help control harmful activity in supporting brain cells.

The mysterious hum heard around the world may finally have an explanation

1 month 2 weeks ago
The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external.

Phytochemicals modulating HSF-1-associated pathways: A systematic review of longevity-extending mechanisms in Caenorhabditis elegans

1 month 2 weeks ago
Aging is characterized by progressive loss of proteostasis, and heat shock transcription factor 1 (HSF1) is the master regulator of the cellular stress response, making it an attractive pharmacological target for interventions aimed at extending lifespan. However, a systematic synthesis of phytochemicals that modulate HSF1 has been lacking. Following PRISMA 2020 guidelines, we systematically searched PubMed, Web of Science, Scopus, Embase, and the Cochrane Library from March 2016 to March 2026,...

The circulating senosome: Blood as the therapeutic interface of aging

1 month 2 weeks ago
Aging is commonly framed as a progressive accumulation of cellular and tissue-level damage. However, the aged organism does not decline as a collection of isolated organs. Aging is communicated systemically through blood-borne signals that connect senescent cells, immune remodeling, vascular dysfunction, metabolic stress, dysbiosis, and chronic inflammation. I propose the concept of the circulating senosome to describe the composite network of age-associated circulating mediators, including...
