Aging & Longevity

Age-related hearing loss (ARHL) is an increasingly common feature of aging and has been linked to poorer psychosocial wellbeing and increased dementia risk. Individuals with ARHL experience speech perception difficulties in noisy environments, wherein the brain must "turn up the volume" or upregulate neural activity to accurately parse speech from background noise. As the aging population steadily increases worldwide, it is essential to develop effective, non-invasive, and easily attainable...

Myofascial pain syndrome (MPS) in the elderly is a significant contributor to chronic pain and functional decline, driven by a unique set of age-related pathophysiological challenges. Core geroscience principles-including sarcopenia, inflammaging, and cellular senescence-converge to create a state of heightened central sensitization that amplifies pain. Traditional pharmacotherapy is fraught with risks in this population due to polypharmacy and vulnerability to adverse effects, with many common...

BACKGROUND: Sustained attention is a complex cognitive function required for the successful performance of tasks such as walking, cycling, driving, conversations and other prolonged tasks. Deficits of this function are associated with frailty, falls, and general cognitive decline in older adults. Sustained attention declines with age and is impaired in many neurological disorders. However, little is known about the underlying neurophysiological characteristics of sustained attention deficits in...

The association between aging and cancer has been extensively documented in observational studies, but their shared genetic basis remains unclear. Leveraging genome-wide association studies summary statistics of aging and pan-cancer (87,531 cases and 314,193 controls) within the European population, genetic correlation and Mendelian randomization analyses were used to estimate genetic correlations, and infer causal relationships between seven aging-related traits and pan-cancer. We further...

The microbiome is a key determinant of organismal health, yet inter-individual variability and heterogeneous responses to environmental conditions complicates the understanding of its effects on hosts. Here, we present a comprehensive analysis using the Drosophila Genetic Reference Panel (DGRP) to investigate how the interplay between host genetic variation and diet influences microbiome composition, and to assess whether microbiome features in young flies can be used to predict lifespan and...

The global demographic shift toward aging has precipitated a surge in age-related ocular pathologies, imposing a formidable public health challenge that demands urgent intervention. Blinding disorders such as age-related macular degeneration (AMD), cataracts, and dry eye disease exemplify this crisis, with their pathogenesis being intrinsically linked to tissue-specific aging processes in the eye. At the molecular level, core pathways including telomere attrition, oxidative stress, cellular...

Nitric oxide (NO) is a pleiotropic gaseous mediator that regulates tissue homeostasis. At physiological levels, it functions as a precise signaling molecule through soluble guanylate cyclase (sGC) activation and the reversible S-nitrosylation of cysteine residues. However, in the context of aging and fibrosis, oxidative stress disrupts this balance. The increased generation of superoxide (O₂•⁻) anions diverts NO from homeostatic signaling to form peroxynitrite (ONOO⁻), a potent oxidant. This...

Aging, stress-related disorders, and chronic disease are often examined across separate domains-stress physiology, nutrition, psychiatry, and geroscience-despite converging on shared phenotypes of functional decline and reduced resilience. Although adaptive responses to stress are well characterized, why comparable exposures yield sustained resilience in some individuals but progressive dysfunction in others remains insufficiently explained. We propose that the missing unifying constraint is not...

This study examined associations between dietary habits and the risk of developing Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE)-predicted late-life dementia risk in Korean adults. A total of 5,042 participants aged 40-69 years were included. We assessed associations between dietary patterns-the Mediterranean diet, Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, Korean Healthy Eating Index (KHEI), and Empirical Dietary Inflammatory Index...

Vitamin K2 is a fat-soluble vitamin that has been reported to exhibit significant anti-stress activity. Anti-stress properties are considered to be closely associated with lifespan extension. Therefore, we investigated the effects of vitamin K2 on the lifespan and stress resistance of Caenorhabditis elegans, as well as the underlying mechanisms. In the present study, we found that the effects of Vitamin K2 on C. elegans are concentration-dependent. High concentrations (10 μM) of Vitamin K2 are...

Life's Essential 8 (LE8) provides a multidimensional framework to assess cardiovascular health (CVH) in aging populations. The objective of this study was to describe LE8 component scores and their variation by age, sex, and psychosocial factors in middle-aged and older adults from Cádiz, Spain. Cross-sectional data were analyzed from 495 adults aged 50-79 years (59.4% women; 34.7% ≥ 65 years). LE8 scores were calculated following American Heart Association guidelines. Group comparisons used...

UVB-induced lens epithelial cell (LEC) senescence is among the important factors involved in the pathogenesis of age-related cataract (ARC). This study aimed to investigate the anti-aging effect of metformin (Met) and to elucidate the molecular mechanisms underlying this effect. RNA sequencing, nontargeted metabolomics analysis and network pharmacology were conducted. The expression of senescence indicators (P53 and P21^(Cip1)) and senescence-associated β-galactosidase (SA-β-gal) activity were...

CONCLUSIONS: A self-administered online geriatric screening tool adapted from the ICOPE framework is feasible, acceptable, and effective in detecting GSs in primary care. The high prevalence of GSs highlights the urgent need for scalable digital solutions. Integrating online screening into primary care workflows could facilitate early identification, optimize resource use, and promote healthy aging in resource-constrained settings.

CONCLUSIONS: Our findings suggest that the use of white noise can result in improving sleep quality and may be helpful in reducing fatigue in community-dwelling older adults and can be recommended as an low effort, low-cost and safe strategy to enhance sleep and reduce fatigue in older individuals.

Cancer-associated cachexia (CAC) is a multifactorial wasting syndrome characterized by progressive loss of fat and lean mass, systemic inflammation, and poor therapeutic responsiveness. While brown adipose tissue (BAT) is traditionally considered a protective, energy-dissipating organ, its qualitative remodeling in CAC remains poorly characterized.Here, we demonstrate that CAC induces a senescent conversion of BAT, marked by thermogenic failure, fibrosis, inflammation, and acquisition of a...

CONCLUSIONS: The use of an aging simulation suit was associated with improvements in specific dimensions of clinical empathy among healthcare professionals working in long-term care. This educational tool offers a valuable experiential approach that enhances understanding and compassion toward older adults. However, these findings are limited to short-term, self-reported measures, and no behavioral or patient outcome data were collected. Further longitudinal studies are needed to determine the...

Physical resilience is a term used to describe an individual's response to physical and physiological stressors across the fields of gerontology and rehabilitation sciences. However, the term has not yet undergone a rigorous examination of its underlying assumptions, which has hindered its theoretical development and empirical measurement. This paper reviews the existing definitions of physical resilience in the context of human physical and psychological systems to examine its underlying,...

Global population aging has sharply increased the prevalence of age-related degenerative diseases, posing severe challenges to global public health and socioeconomic stability. Growing evidence links these disorders to the bidirectional crosstalk between gut microbiota and cellular senescence, yet the integrated interaction network governing multi-organ degeneration remains poorly defined. Age-related gut microbial remodeling reshapes metabolite profiles: beneficial metabolites mitigate cellular...
