Filter by:The main aim of this project is to analyze and understand the meaning of explicit requests to hasten death (euthanasia and assisted suicide) from older people living in an Establishment of accommodation for dependent old persons. This involves conducting interviews with patients, carers to whom the request has been expressed and a relative chosen by the patient. This study aims to describe the request over time. This will be done through two series of interviews, one as soon as it is first expressed, then one week later.
The Aging Mastery Program® (AMP) is designed to inform, encourage, and support older adults as they take steps to improve their lives and stay engaged in their communities. The program incorporates evidence-informed materials, expert speakers, group discussion, peer support, and small rewards to give participants the skills and tools they need to achieve measurable improvements in managing their health, remaining economically secure, and contributing actively to society. L.A. CAPRA in partnership with the National Council on Aging, City of Los Angeles and the Los Angeles County Department of Aging will evaluate the effectiveness of the AMP program across 5 community-based senior sites. The overall objective of the proposed study is to evaluate the effectiveness of AMP program on improving the health and well-being of older adults using a randomized wait-list controlled trial.
The purpose of this study is to determine the respective roles of aging and schizophrenia in the regulation of metamemory using a generation strategy. 4 groups will be necessary to comparison: Adult patients (18-45 years) Adult controls (18-45 years) Aged patients (≥ 59.5 years) Aged controls (≥ 59.5 years) The effects of age and the disease could lead to interaction in regulating metamemory. The effect of age would be aggravated by the disease.
FIT-AGING will determine the effect of different exercise modalities on α-Klotho protein (primary outcome) in sedentary healthy adults. FIT-AGING also investigate the physiological consequences of activating Klotho gene (secondary outcomes).
The purpose of REACT project is to provide cost-effective way to promote physical activity and reduce sedentary time among older adults. This is done by examining the efficacy of activity tracker based intervention on wake-time physical activity, sedentary time, sleep and other health outcomes among recent retirees. REACT study will be the first randomized physical activity trial targeted to time window right after retirement.
The goal of this pilot and feasibility study is to investigate the effects of a short course of metformin therapy on a surrogate marker of cellular senescence and autophagy among adult patients with prediabetes. The overall hypothesis is that metformin will have beneficial effects on longevity and quality of life by inducing autophagy downstream of activating adenosine monophosphate-activated protein kinase (AMPK) and inhibiting mechanistic target of rapamycin (mTOR) through potential effects of reduced inflammation, reduced degeneration of muscle and tendon tissue, antineoplastic effects, reduced obesity and hyperglycemia, preserved cardiovascular functions, and/or the prevention of neurodegeneration (such as age-associated dementia). This pilot study will address the following aim: Demonstrate that metformin therapy will increase cellular autophagy as an inverse correlate of aging as measured by increases in Microtubule-associated protein 1A/1B-light chain 3 (LC3) scores. Hypothesis 1: In addition to beneficial effects on glycemia, body weight, and body composition, metformin therapy exerts beneficial effects on surrogate measures of autophagy and aging. Primary outcome: Increased levels of LC3 in leukocytes.
Dysfunction of adipose tissue in obesity, inflammation and aging: mechanisms and effects of physical exercise and omega-3 fatty acids.
Emerging evidence from social neuroscience suggests that prefrontal cortex (PFC), insular and anterior cingulate cortex (ACC) regulate social and emotional responses to acute threats to social connectedness among young adults. Deficient neural reserve or overused neural compensation resulting from neurodegeneration is commonly observed in these frontal regions in old age. This aging-related "neural depletion" may have implications for how older adults respond to social threats, potentially increasing maladaptive emotional and social behavioral responses, such as social anxiety and social avoidance, which contribute to social disconnectedness. The central hypothesis is that cognitive deficits and associated aging-related 'neural depletion' in the frontal regions will contribute to maladaptive social-emotional responses to a social stressor -- social exclusion. Ultimately, maladaptive responses to acute social stress, such as social anxiety and avoidance, can compromise social connectedness by increasing social strain and isolation. The investigators have recently developed a neuroplasticity-based cognitive training program, called vision-based speed of processing (VSOP) training, targeting multiple aspects of cognitive capacity (e.g., attention, working memory and inhibition) and incorporating the speed component to improve the efficiency of these cognitive processes. VSOP training also targets several neural networks seeded in ACC and insular (default mode network) or PFC (the frontal-striatal network and central executive network). These networks also overlap with neural substrates of emotion regulation. Notably, VSOP training appears to improve emotion regulation, as depressive symptoms were reduced in older adults following VSOP training. Finally, the autonomic nervous system (ANS), critical to stress adaptation, is regulated by these frontal regions. The objective of the proposed pilot study is to provide proof-of-concept for the hypothesis that improvements in older adults' cognitive capacity, frontal regions' neural efficiency, and ANS function via the VSOP training will be associated with more adaptive social-emotional response to social exclusion, which, in turn, should confer longer-term protection for older adults' sense of social connectedness. Randomized Controlled Trial Design: 30 older adults will be randomly assigned to engage in 6-week VSOP training, or to an active control group. Differential changes from baseline to post-training in cognitive capacity, neural efficiency, and ANS function, and sense of social connectedness, will be compared between VSOP control groups. A social exclusion paradigm ('cyberball' task) will be conducted post-training to evaluate VSOP training effects on social-emotional responses to social exclusion, including anxiety and motivation for social affiliation.
Sarcopenia, the loss in muscle mass with age, is associated with several negative health outcomes including cancer, stroke, cardiovascular disease and diabetes. This loss of muscle mass remains relatively steady following 50 years of age however it can be accelerated with periods of disuse associated with hospitalization, fracture or surgery of the hip or simply influenza. Also associated with periods of disuse, is a lack of energy intake as hospitalizations often result in undernourishment. The consumption of protein has been shown to stimulate muscle growth and therefore the investigators are wondering whether it is able to offset the loss of muscle mass associated with disuse. Therefore, the purpose of the study is to examine the effects of protein consumption combined with mild caloric restriction on changes in muscle mass and function during a period of disuse as well as during a period of recovery .
This is a randomized, double-blind, single-center, placebo-controlled Phase 2 trial enrolling 66 healthy elderly subjects (33 placebo and 33 AMAZ-02 administration) who are ≥65 and ≤ 90 years of age with evidence of low mitochondrial function. AMAZ-02 or placebo will be orally administered for 4 months.
