Social isolation, loneliness, and positive affect before and during the COVID-19 pandemic in very old adults living in Germany: a quasi-experimental multi-sample study
CONCLUSIONS: Cumulative risks during the COVID-19 pandemic escalated, with pandemic responses such as lockdowns increasing the adverse effects of social isolation and loneliness on positive affect of very old adults. Our pooled-multi-sample design allows a quantitative investigation of an understudied population, offering researchers new insights and an empirical strategy to utilize.
Frailty progression before and after diabetes onset among older adults in china: a nationwide cohort study
CONCLUSIONS: Incident diabetes was associated with accelerated progression of frailty in older adults, particularly in the domain of instrumental activities of daily living. Regular functional assessments and targeted interventions following diabetes diagnosis was important, especially for high-risk subgroups including the oldest-old, unmarried individuals, and those with lower BMI.
The Drosophila escape motor circuit shows differential vulnerability to aging linked to functional decay
Brain aging can cause cognitive and motor disabilities which often correlate with changes in dendritic branch, axon collateral, and synapse numbers. However, from invertebrates to mammals, age-related decline is typically restricted to specific neuron types or brain parts, indicating differential vulnerability. The rules to pinpoint the susceptibility of distinct brain elements to aging remain largely unknown. Here, we combine longitudinal studies with neuroanatomical, electrophysiological, and...
Effect of Hong Huang Tang on memory enhancement and mitigation of microgravity-induced oxidative stress in C. elegans
Ziziphus jujuba Mill. (ZJ) is a traditional medicinal plant known for its antioxidant, anti-inflammatory, and neuroprotective properties, yet its role in learning and cognitive regulation remains insufficiently explored. Huang Jing (Polygonatum sibiricum), a Qi- and Yin-tonifying herb in Traditional Chinese Medicine, has historically been used to combat fatigue, support brain function, delay aging, and regulate metabolic balance. In this study, we evaluated the neuroprotective and antioxidant...
Cardiometabolic-Inflammatory Risk Factors and Cognitive Decline Among Older Indians-Report From a Nationally Representative, Longitudinal Study
CONCLUSION: Cardiometabolic risk factors play a significant role in late-life cognitive decline and death among older Indians. These longitudinal relationships from LASI-DAD highlight potentially modifiable risk factors and inform potential prevention policies.
Changes in the risk of depression in older adults in Poland from 2010 to 2019: results of two nationwide surveys
CONCLUSIONS: Higher prevalence of clinically relevant depression in certain groups and increased risk possibly reflect unfavorable socioeconomic changes that occurred for the elderly population in Poland in the analyzed period.
Smart aging: integrating AI into elderly healthcare
Artificial Intelligence (AI) is transforming geriatric healthcare by improving early disease detection, optimizing patient management, and enhancing clinical decision-making. AI-driven tools, including machine learning (ML) algorithms, predictive analytics, and assistive robotics, are increasingly utilized to address challenges associated with aging, such as frailty, multimorbidity, polypharmacy, and fall prevention. These technologies can facilitate personalized medicine, improve diagnostic...
A Scoping Review of Delphi Studies: Trends and Gaps in Aging Research
This scoping review provides key trends in the use of the Delphi method applied to geriatrics and gerontology research, and documents key information that can be used in the planning of future Delphi studies, like recruitment rates, number of Delphi rounds and panelists, attrition, consensus definitions, and stakeholders engaged.

Monoacylglycerol lipase inhibition improves motor function and reduces oxidative stress in hemiparkinsonian mice
Parkinson's Disease (PD) is characterized by motor symptoms, loss of dopaminergic neurons, and oxidative stress in the Substantia Nigra pars compacta (SNpc) and striatum of patients, as well as in models of parkinsonism. Recent studies show that the endocannabinoid system present in the basal ganglia has a strong influence on the progression of PD, with the inhibition of the enzyme Monoacylglycerol Lipase (MAGL) being a promising therapeutic strategy. Therefore, the aim of this study was to...
Supportive Smart Homes: Is It Time to Get Serious About Aging in Place?
Worldwide, the population is aging. Most older adults would prefer not to move from their current residence; however, there are human resource challenges in home care service provision. Smart home technology has evolved over the past decades and could provide an adjunct to home care and potentially delay moving to a higher level of care. This paper provides an overview of supportive smart home technology, which expands smart home technology to enable feedback and action based on daily...
Strength but not power training increases soluble alpha klotho levels in pre-frail older adults
CONCLUSION: Twelve weeks of ST, but not PT, significantly increased circulating sαKL levels in pre-frail older adults. Given the beneficial health effects of increased sαKL, these findings suggest that ST may offer additional biological advantages relevant to healthy aging. sαKL may serve as a promising biomarker for training-induced adaptions, but prospective trials are needed to confirm long-term effects and further clarify underlying mechanisms.
Development and validation of a simplified time-dependent interpretable machine learning-based survival model for older adults with multimorbidity
Multimorbidity elevates late-life mortality, yet existing tools remain complex. Using two nationally representative Chinese cohorts-the Chinese Longitudinal Healthy Longevity and Happiness Family Study (CLHLS-HF; n = 8675) and the China Health and Retirement Longitudinal Study (CHARLS, n = 4171)-we developed and externally validated a simplified, time-dependent, interpretable survival model. A four-stage feature-selection pipeline (univariate Cox, L1-penalized Cox, multi-model importance with...
Mitochondrial RNA cytosolic leakage drives the SASP
Senescent cells secrete proinflammatory factors known as the senescence-associated secretory phenotype (SASP), contributing to tissue dysfunction and aging. Mitochondrial dysfunction is a key feature of senescence, influencing SASP via mitochondrial DNA (mtDNA) release and cGAS/STING pathway activation. Here, we demonstrate that mitochondrial RNA (mtRNA) also accumulates in the cytosol of senescent cells, activating RNA sensors RIG-I and MDA5, leading to MAVS aggregation and SASP induction....
