The effect of a complex intervention for older adults on medication adequacy: results from the + AGIL Barcelona program

7 hours 36 minutes ago
CONCLUSIONS: While the + AGIL Barcelona program had a limited quantitative impact on polypharmacy, it significantly reduced PIMs' use, particularly in nervous system-acting medications, which are involved in increased risk of falling and cognitive impairment in older adults. The study highlights the importance of medication review in multidimensional frailty management, although future research with larger samples and standardized medication review protocols is needed.

Factors associated with the engagement in meaningful activity and occupational balance in institutionalised older adults: a prospective observational cohort study

7 hours 36 minutes ago
CONCLUSIONS: These findings underscore the need to review the type and range of activities offered in institutional settings, reducing time devoted to highly structured leisure activities and promoting more enriching experiences. To do so, experience-based co-design approaches involving institutionalised older adults and professionals in these settings are essential to develop person-centred programmes to enhance engagement in meaningful activities and occupational balance. Future research...

A single protein may be holding back CAR T cancer therapy

1 day 2 hours ago
A newly identified protein may be one of the biggest obstacles holding CAR T-cell therapy back. Researchers found that NFIL3 causes these engineered immune cells to become exhausted and lose their cancer-fighting power over time. When NFIL3 was disabled, the cells remained stronger for longer and controlled tumors more effectively in animal models.

Scientists discover gut bacteria that may help protect against autism and ADHD

1 day 3 hours ago
A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby’s genes and gut microbes. Researchers found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life, and certain combinations were linked to early signs of autism and ADHD by age three.

Exploratory multi-omics analysis for candidate biomarker identification in Parkinson's disease

1 day 7 hours ago
Parkinson's disease (PD) is a progressive neurodegenerative disorder lacking established clinical biomarkers. We performed an exploratory multi‑omics analysis of transcriptome and proteome data from small PD and control cohorts at Huaihe Hospital of Henan University. Using two local datasets, we identified 124 differentially expressed genes (DEGs) and 28 proteins, then performed protein‑protein interaction (PPI) and gene set variation analysis (GSVA). After intersecting with 2,964 DEGs from Gene...

Associations Between Posttraumatic Stress and Comorbidities of Traumatic Brain Injury and Substance Use Disorders with Alzheimer's Disease in Older Veterans: A Narrative Review

1 day 7 hours ago
Posttraumatic stress disorder (PTSD) exhibits high rates of comorbidity with Substance Use Disorders (SUDs) and Traumatic Brain Injury (TBI), especially in older adults who are subject to the effects of psychological trauma due to combat exposure, health-related and psychosocial outcomes, and aging. This narrative review explores the associations between PTSD and comorbidities of psychoactive substance abuse and traumatic brain injuries on the incidence of Alzheimer's disease (AD) in veterans...

DREAM repressive activity links somatic mutation, lifespan and disease

1 day 7 hours ago
The DREAM complex has emerged as a central repressor of DNA repair, raising questions as to whether such repression exerts long-term effects on human health. Here we establish that DREAM-associated activity significantly impacts lifetime somatic mutation burden, and that such effects are linked to altered lifespan and age-related disease pathology. First, joint profiling of DREAM-associated activity (quantified from the expression of genes transcriptionally repressed by DREAM) and somatic...

Intracellular mitochondrial-subcellular communication: A Regulator of Myocardial Energy Metabolic Homeostasis in Heart Failure

1 day 7 hours ago
Heart failure (HF) is characterized by a severe disruption of myocardial energy metabolism, with mitochondrial dysfunction standing as a central pathological feature. However, the upstream regulatory mechanisms that drive metabolic remodeling, particularly across distinct HF phenotypes, remain inadequately defined. Mounting evidence reveals that, beyond their metabolic role, mitochondria act as central signaling hubs. This review proposes that dysfunctional mitochondrial-organelle crosstalk is a...

Peripheral immunosenescence biomarkers and longitudinal cognitive decline: a large population-based study

1 day 7 hours ago
Peripheral immunosenescence has been increasingly implicated in dementia pathogenesis. However, the contributions of specific lymphocyte subsets to cognitive outcomes remain poorly defined, and evidence from large-scale longitudinal studies is scarce. We leveraged data from the US Health and Retirement Study (n = 7444; mean age: 67.7 ± 9.7 years). Our primary analysis calculated three ratio metrics to quantify T-cell immunosenescence: the CD4:CD8 ratio, CD4 + EMRA: Naïve and CD8 + EMRA: Naïve...

Reductive death is averted by a conserved de novo lipogenic switch

1 day 7 hours ago
Biguanides, including metformin, the world's most prescribed oral hypoglycemic, extend health span and lifespan in vertebrates and invertebrates. Given the widespread use and apparent safety of metformin, it is assumed that its effects are not associated with toxicity, except when in marked excess. Here, we determine that accumulation of damaging reducing equivalents is an unanticipated toxicity associated with biguanides, defense against which requires post-transcriptional protection of de novo...

Association between physical activity levels and intrinsic capacity impairment among Chinese older adults: A cross-sectional study based on CHARLS

1 day 7 hours ago
CONCLUSIONS: Physical activity levels were non-linearly associated with the risk of intrinsic capacity impairment, with moderate levels being associated with a lower risk. This study further identified marked heterogeneity in the associations between physical activity and different intrinsic capacity domains, suggesting that the benefits are not uniform across functional domains. These findings highlight the importance of maintaining an appropriate level of physical activity and support the...

Association between urinary phytoestrogens and sarcopenia in older adults: A cross-sectional study

1 day 7 hours ago
CONCLUSION: This study indicates that phytoestrogens are associated with sarcopenia, and the direction of this association depends on the specific type of estrogen. The findings reveal that O-DMA, Enterolactone, and total phytoestrogens possess a preventive effect against sarcopenia in female and it also reveal that Daidzein possess a preventive effect against sarcopenia in male.

Aging in Behcet's syndrome: an overlooked risk for late-life cognitive impairment

1 day 7 hours ago
Behçet's syndrome (BS) is a chronic multisystemic inflammatory disorder with a heterogeneous clinical course. A severe subset with central nervous system involvement (neuro-Behçet's syndrome, NBS) carries substantial morbidity. While disease activity often decreases with age, the long-term neurological and cognitive outcomes remain poorly defined. Emerging evidence indicates that vascular insufficiency, chronic inflammation, and central nervous system involvement may contribute to cognitive...
