Filter by:Cardiovascular diseases are the leading cause of morbidity and mortality and contribute most to healthcare costs in the U.S. Age is the strongest cardiovascular disease risk factor, with >90% of all deaths from cardiovascular disease occurring in adults >50 years old. The age-associated increased risk of cardiovascular disease is due, in large part, to the development of arterial dysfunction, including endothelial dysfunction and stiffening of the large elastic arteries. Therefore, novel, effective interventions that improve arterial function will have a large public health impact by decreasing the risk of cardiovascular diseases. The short-chain fatty acid acetate is endogenously produced by the gut microbiome from fermentation of dietary soluble fiber. High-fiber diets reduce risk of cardiovascular diseases, but unfortunately, a low percentage of Americans meet guidelines for adequate dietary fiber intake and, despite nationwide efforts to improve this, trends in fiber intake have not improved over the last 20+ years. Thus, directly supplementing acetate may be a more practical and feasible intervention for effectively improving arterial function in older adults and reducing the risk of cardiovascular diseases. The investigators will conduct a study to determine the efficacy of 12 weeks of oral supplementation with acetate for improving arterial function in late middle-aged and older (50+ years) adults. They will also assess the safety and tolerability of acetate supplementation in these adults and perform innovative mechanistic analyses to determine how acetate supplementation improves arterial function. The investigators hypothesize that oral acetate supplementation will improve arterial function by decreasing oxidative stress and increasing nitric oxide bioavailability, and also hypothesize that acetate supplementation will be safe and promote high rates of adherence.
Hospitalized older patients usually remain bedridden for many hours and this may lead to the appearance of unwanted negative consequences, such as cognitive or physical decline upon discharge. Our study will analyze whether an intervention consisting of a multicomponent training programme applied to patients over the age of 60 who are hospitalized for acute medical conditions in an Oncology Department of a tertiary hospital improves functional capacity and cognitive function. A total of 50 hospitalized older adult patients will be recruited in the Hospital Universitario de Navarra, Pamplona, Spain. The participants will be randomized and included in an exercise intervention (n = 25) or a control (n = 25) group (hospital usual-care). The intervention consists of a multicomponent exercise training programme that will take place for 3 consecutive days (2 sessions/day). The control group will receive usual hospital care, which will include physical rehabilitation when needed. Functional and cognitive impairment after and during acute hospitalization in older adults are major determinants of the later need for health resources. If our hypothesis is correct and shows that a multicomponent, individualized and progressive exercise programme is an effective therapy for improving the functional capacity of acutely hospitalized older patients compared to usual care, a change in the current system of hospitalization may be justified in oncogeriatric patients with medical conditions
The proposed study is designed to evaluate the effect of at-home executive function training on cognition and mobility in older adults with age-related hearing loss (ARHL), older adults with normal hearing, and middle-aged adults.
There is a decrease in cardiovascular and neuromuscular functions, which leads to reduced performance with advancing age. Physical activity provides health benefits, prevents and treats cardiovascular and neuromuscular disease. The aim of this project is to describe cardiovascular and neuromuscular function in active and sedentary subjects of different ages.
The aim of this study as part of the SCOBES-AR project is to establish and test a protocol for implementation and usability of mixed reality-enhanced multidisciplinary screening tool for early detection of cognitive impairments in the elderly.
This study will investigate whether transcranial direct current stimulation (tDCS) enhances the effects of cognitive training in older adults with depression.
Over time, lifespan is extending, the population is aging, and accordingly there is a great demand for hospital beds in nursing homes, increasing attention to this population and the services they receive. Mostly, elderly population living in nursing homes suffers from dementia, Alzheimer, depression, agitation, and other diseases that require multidisciplinary treatment. In addition to the medical and pharmacological treatments that patients receive to maintain functional medical status, there is a great need for non-pharmacological treatments, that may improve quality of life, mental well-being, and life satisfaction. There are several treatment approaches of multisensory stimulation environment (MSSE). MSSE in the Snoezelen room therapy recognized as benefiting the patients' physical, mental, and emotional health status. In addition, there is great importance of intervention by social interaction, support, and encouragement. However, the effect of combined intervention of MSSE in Snoezelen room therapy and social support, has not yet been sufficiently studied in elderly patients in nursing homes. These two interventions - together - are supposed to have an increased effect on physical and mental wellbeing of elderly.
The primary objective of the Vanderbilt Alzheimer's Disease Research Center (VADRC) is to provide local and national researchers with access to a well-characterized and diverse clinical cohort, including participant referrals, biosamples, clinical data, and neuroimaging data. The VADRC Clinical Core will create an infrastructure to support research efforts of both local and national investigator studies to develop early detection, prevention, and treatment strategies for Alzheimer's disease. The Clinical Core intends to enroll up to 1000 participants, including individuals who are cognitively unimpaired, have mild cognitive impairment, or have Alzheimer's disease. This cohort of about 1000 participants will be called the Tennessee Alzheimer's Project. Participants will be seen annually for comprehensive clinical characterization and then referred to other studies to enhance Alzheimer's disease research activities.
This study will use an observational cohort to cross-sectionally and longitudinally relate vascular health to clinical, imaging, and biological markers of early Alzheimer's disease and cerebrovascular disease among aging adults. Adjusting for relevant clinical covariates, we will test the hypothesis that vascular health is associated with clinical, brain magnetic resonance imaging (MRI), neuropsychological, and cerebrospinal fluid markers of early cerebrovascular and Alzheimer's disease changes (i.e., prior to the onset of significant cognitive decline or dementia). Secondarily, we will examine medical and genetic factors that might mediate associations between vascular health and brain aging, such as inflammatory processes, insulin resistance, and genetic factors (e.g., APOE, a susceptibility risk factor for dementia). Findings will advance knowledge regarding the role that vascular health plays in brain aging.
Chronic pain is one of the main factors influencing workers' retention at work. Considering that the prevalence of suffering from chronic pain increases with age, older workers are most likely to be absent from work because of their pain. Transcranial direct current stimulation (tDCS) is a treatment option to reduce chronic pain. This study aims to document the effect of tDCS on pain and work retention in older workers and to compare the traditional tDCS protocol (5 sessions) with an enhanced protocol (11 sessions).
