Physical performance in the elderly

Creating a reusable adhesive that can hold objects on a wall and can yet be easily removed al for researchers in the adhesives community for many years. Geckos and other climbing organisms demonstrate just this ability: to hold large loads (on-state) due to specialized digits and microstructures, yet they are also able to quickly peel their feet from a surface while climbing (off-state). Inspired by the simplicity of the gecko's geometric switching mechanism, we have investigated the use of origami design methods to create geometries that can transition from a stiff configuration to a more flexible and easily peeled configuration...

METHODS: Participants (N = 998) were from the Hispanic Established Population for the Epidemiologic Study of the Elderly (2007-2016)...

BACKGROUND: Family caregivers play a crucial role in providing physical, emotional, and social support to the elderly, allowing them to maintain their independence and stay in their preferred living environment. However, family caregivers face numerous challenges and require specific knowledge and skills to provide effective care. Therefore, understanding the knowledge and skills required for effective family caregiving in elderly home care is vital to support both the caregivers and the elderly recipients...

Both ageing and hypertension are clinical factors that may lead to a higher propensity for dissection or rupture of ascending thoracic aortic aneurysms (ATAAs). This study sought to investigate effect of valve morphology on regional delamination strength of ATAAs in the elderly hypertensive patients. Whole fresh ATAA samples were harvested from 23 hypertensive patients (age, 71 ± 8 years) who underwent elective aortic surgery. Peeling tests were performed to measure region-specific delamination strengths of the ATAAs, which were compared between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV)...

Intrinsic capacity(IC) is a measure of physical, cognitive, vitality, psychological, and sensory abilities which determines functional ability. Decline in IC has been shown to accelerate the trajectory of frailty. We aim to show the impact of exercise (Ex) and cognitive stimulation therapy (CST) on (i) IC domains and composite score (ii) frailty and functional ability in pre-frail older adults. Secondary analysis of data from a pre-post intervention study of pre-frail older adults ≥ 65 years attending primary care clinic...
