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 purpose of this pilot research is to test the feasibility of two interventions focused on either reducing total calorie intake or reducing the total time that calories are ingested each day in older adults. Participation in this research will involve visits to our clinic for testing and weekly intervention visits (in-person or remote depending on group assignment) for nine months with total participation lasting about a year.
The purpose of this pilot study is to demonstrate the safety and feasibility of administering intermittent doses of Dasatinib and Quercetin (D+Q) in older adults at risk of Alzheimer's disease (AD). The study will evaluate whether giving D+Q may improve cerebral blood flow regulation, mobility, and cognition in older adults, and thus may prevent progression to Alzheimer's disease.
This study aims to assess the digestibility and efficacy of the study groups previously developed innovative plant-based protein and fibre products.
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.
The aim of this study is to evaluate the relationship between age-related anorexia and personality traits in elderly individuals with comorbidities.
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.
This research project aims to determine whether post exercise hot water immersion can improve vascular and cardiometabolic health to a greater extent than post exercise thermoneutral water immersion in healthy middle-aged adults. The study will take place over an 8 week period where participants will do a combination of aerobic exercise and water immersion 3 times per week. The study will be a randomised controlled trial comparing 8-weeks of post exercise hot water immersion (EX+HWI) to post exercise thermoneutral water immersion (EX+TNWI).
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.
