CONCLUSION: Cognitive impairment in elderly individuals in Chengdu is serious. We can intervene in and improve cognitive impairment in elderly people by controlling blood pressure and blood sugar, treating depressive and anxiety symptoms and developing community colleges for elderly people and increasing satisfaction with life.

CONCLUSIONS: Our findings indicate that poor sleep quality is related to various manifestations of long COVID in older populations. A comprehensive assessment and multidisciplinary management of sleep health and long COVID may be essential to ensure healthy aging in the future.

Unintentional weight loss in older populations is linked to greater mortality and morbidity risks. This study aims to understand the metabolic mechanisms of unintentional weight loss and their relationship with body composition changes in older adults. We investigated plasma metabolite associations with weight and body composition changes over 5 years in 1335 participants (mean age 73.4 years at Year 1, 51% women, and 33% Black) from the Health, Aging and Body Composition (Health ABC) study....

This study aimed to document the typology of social participation and network among older Canadians and examine their associations with health. Using 2011-2015 cross-sectional data from the Canadian Longitudinal Study on Aging, a latent profile analysis was conducted to identify patterns of social participation and network, and multinomial logistic regressions examined associations with self-rated health. Four types of social participation and networks characterized older Canadians: diverse...

Integrating dietary interventions have been extensively studied for their health benefits, such as Alzheimer's disease, Huntington's disease, and aging. However, it is necessary to fully understand the mechanisms of long-term effects and practical applications of these dietary interventions for health. A 10-week intermittent fasting (IMF) regimen was implemented on the aging animals in the current study. The variations of cerebral functions were analyzed employing a comprehensive experimental...

Epigenetic clocks are a common group of tools used to measure biological aging-the progressive deterioration of cells, tissues, and organs. Epigenetic clocks have been trained almost exclusively using blood-based tissues, but there is growing interest in estimating epigenetic age using less-invasive oral-based tissues (i.e., buccal or saliva) in both research and commercial settings. However, differentiated cell types across body tissues exhibit unique DNA methylation landscapes and age-related...

CONCLUSIONS: Patients' perspectives may enable or hinder deprescribing, emphasizing the importance of soliciting these perspectives during shared decision-making. Effective deprescribing will benefit from understanding patients' perspectives and fostering patient-provider communication about medication changes throughout the disease course.
