Aging & Longevity

CONCLUSIONS: Among older adults in Shenzhen, the burden of stroke with comorbid hypertension and diabetes showed a long-term upward trajectory over the study period. Model-based projections suggested that the burden may increase from 2024 to 2033, particularly among males and older age groups. These findings provide population-level descriptive and projection evidence that may inform risk stratification and health service planning for ageing urban populations.

CONCLUSION: Life satisfaction in later life is associated with a multidimensional interplay of structural resources, health status, and existential orientation. Socioeconomic security and religious belief emerged as significant predictors of well-being, after controlling for health status. These findings highlight the importance of integrated policies addressing both material and psychosocial predictors of aging well.

CONCLUSIONS: Uptake and sustained engagement with SP via AAC referral appeared to be shaped less by individual capability than by physical opportunity, social opportunity and motivation. Primary care providers are well placed to facilitate engagement by leveraging trusted patient relationships, while centre managers and policymakers should address structural barriers such as zoning restrictions, language mismatch and age-identity mismatch. These findings offer actionable insights to optimise the...

Age-friendly cities and communities (AFCC), together with initiatives to combat ageism, are recognised as two of the four action areas of the United Nations (UN) Decade of Healthy Ageing, have received global attention. However, there is a lack of understanding regarding the distinct experiences of older adults in their cities and communities, as well as the extent to which these experiences are linked to their perceptions of ageism. Using a sample of 398 older adults from four cities in...

Centenarians - individuals aged ≥100 years - provide a unique human model for understanding resilience to cardiovascular ageing. Although cardiovascular and metabolic diseases, including hypertension, heart failure, atrial fibrillation and chronic kidney disease, are common in centenarians, their onset is typically delayed relative to that in individuals aged 80-100 years. Centenarians characteristically have structural changes in the heart and vessels, including concentric left ventricular...

Aging is accompanied by a progressive decline in immune function, increasing susceptibility to infections, cancer, and poorer treatment outcomes. The diversity of the T cell receptor (TCR) repertoire, reflecting the capacity to recognize diverse antigens, is known to decline with age. However, how intrinsic and extrinsic factors jointly shape TCR diversity and its rate of decline, as well as the extent to which this diversity influences clinical outcomes in cancer, remain poorly characterized....

Mitochondria are central regulators of cellular metabolism, integrating energy production, redox balance, and signaling pathways that shape aging trajectories. If mitochondrial organization contributes to lifespan divergence, exceptionally long-lived species should exhibit distinctive metabolic signatures reflecting adaptations promoting long-term cellular maintenance. Comparative approaches across species with extreme lifespan variation provide a powerful framework for identifying potential...

Ginsenoside Rg1, the main active component of Panax ginseng, has been shown to improve mitochondrial function and delay cell aging by regulating chaperone-mediated mitophagy. However, how Rg1 works in Caenorhabditis elegans is still unclear. In this study, C. elegans was used as a model to study how Rg1 regulates autophagy and mitochondrial function, and to understand its anti-aging mechanism. The results showed that Rg1 treatment significantly kept cells alive and maintained muscle shape in...

The concept of cognitive reserve (CR) and resilience originates from clinicopathological observations that amyloid-β deposition, tau pathology and neurodegeneration do not uniformly translate into clinical dementia, highlighting inter-individual differences in the brain's capacity to tolerate pathology. Although CR and resilience lack a single accepted definition, they broadly describe the ability to maintain cognition in the presence of age-related or pathological brain changes. This review...

CONCLUSION: In a society where appearance is important, appearance management suggests that it can be a psychological mechanism that goes beyond simply pursuing youthfulness and helps with self-awareness, personal growth, and adaptation to the aging process. Appearance management that fosters self-expression and personal capabilities can improve the quality of life of older people.

Aging is associated with functional decline and reduced regenerative capacity in the brain, is also the strongest risk factor for ischemic stroke, which remains a leading cause of mortality and long-term disability worldwide, and is associated with impaired functional recovery. Here, we investigated whether short-term partial cellular reprogramming through cyclic expression of Yamanaka factors (OSKM) in a Tet-ON mouse model under Rosa-26 promoter has any impact on ischemic damage in aged mice....

Minimal hepatic encephalopathy (MHE) is a neurological complication associated with chronic liver disease characterized by subtle cognitive impairment and neuroinflammation, particularly in the aging population. However, the molecular mechanisms underlying age-associated MHE remain poorly understood. The present study investigated the role of Fetuin-A-mediated neuroinflammation and its potential as a therapeutic target in the management of MHE in old rats using pioglitazone in a thioacetamide...

Cognitive reserve (CR) is a broad framework for explaining why individuals differ in cognitive functioning in the face of aging and neuropathology. One influential mechanistic account proposes that cognitively demanding life experiences such as education, occupational complexity, and cognitively stimulating activities augment a domain-general cognitive capacity that subsequently provides resilience. We refer to this more specific claim as cognitive reserve augmentation (CRA). This narrative and...

CONCLUSION: Concordance between epigenetic-clock and clinical-outcome changes was inconsistent, with favorable signals concentrated mainly in selected intermediate outcomes. Epigenetic clocks should currently be considered exploratory or adjunctive biomarkers of intervention response rather than validated clinical surrogate endpoints.

Lipodystrophies are a group of disorders featuring reduced adipose tissue mass or function, which often leads to significant metabolic disease, reduced lifespan and impaired quality of life. Individuals with congenital generalised lipodystrophy (CGL) have severely reduced adipose tissue mass. The loss of healthy systemic lipid storage typically causes hepatic steatosis and lipoatrophic diabetes. In addition, adipocyte-secreted hormones including leptin and adiponectin are dramatically reduced....

Endothelial cells (ECs) are critical regulators of vascular function and exhibit tissue-specialized roles. During aging, these cells become dysfunctional, resulting in increased susceptibility to cardiovascular disease. Although single-cell transcriptomics has revealed extensive endothelial heterogeneity, a comprehensive atlas of human EC transcriptomes over the course of the adult human lifespan has been lacking. Here, we present the Human Aging Endothelial Cell Atlas (HAECA), a harmonized...

CONCLUSION: Bibliometric and semantic analyses indicate growing research interest in cell-type-specific senescence, inflammatory-fibrotic remodelling, HF phenotype heterogeneity, biomarkers, and senotherapeutics. These findings highlight opportunities for integrating mechanistic research with clinical investigation. Future studies should prioritize cell-specific senescence atlases, multidimensional biomarkers, comorbidity-aware HF stratification, and cautious evaluation of senotherapeutics in HF...

Global health policies and the World Health Organization consistently promote aging in place, reflecting the strong preference of older adults to remain in their home environments. Yet frailty, cognitive decline, caregiver exhaustion, and social vulnerability frequently make nursing home admission necessary and position institutional care as the default response to severe dependency. The COVID-19 pandemic exposed vulnerabilities of nursing home care and renewed debate about the sustainability of...
