Filter by:Dietary amino acid supplementation may provide an effective means to promote tendon injury recovery and enhance collagen synthesis. While most published research has been completed in animal models, research with young adults has shown that a leucine-rich whey isolate consumed during a chronic resistance training (RT) intervention resulted in greater gains (~60%) in tendon CSA when compared to placebo. Leucine-rich diets have also improved tendon collagen content in rodents. Further, in our preliminary work utilizing microdialysis, we demonstrate that oral consumption of a leucine-rich amino acid beverage increased delivery of amino acids to tendons in young adults (21-30 years). However, whether aging alters the delivery of amino acids to tendons after oral consumption has not be investigated. In order to optimize amino acid dosing for chronic interventional studies, we wish to determine if aging influences amino acid concentration in the peritendinous (space around the tendon) space after oral consumption.
Sunnybrook Veterans Centre (VC) is a long-term care (LTC) facility with many elderly residents living with swallowing disorders who are at high risk of developing pneumonia from aspirating food/liquid into their lungs. Expiratory muscle strength training (EMST) using a hand-held resistance device over a four week intensive program has been shown to have promising results in improving cough function and reducing aspiration during swallowing in older, community-dwelling adults. The purpose of this study is to explore whether a modified slow-stream protocol of EMST over eight weeks is an effective therapy for improving swallowing safety and lung clearance in elderly VC residents with swallowing disorders. Before and after the eight week therapy program, we will measure participants' cough under spirometry, swallowing under videofluoroscopy, and their swallowing-related quality of life and diet texture modification. A three month follow-up visit will measure swallowing-related quality of life again, as well as record incidence of respiratory tract infections requiring antibiotics in the last three months, to be compared with broader institutional data.
The aim of the current study, therefore, is to determine the feasibility of recruitment and adherence to resistance exercise training interventions performed at low and high loads, to volitional muscular failure, in a trial population that includes both healthy and frail older people.
This study will utilise an assessor blinded, randomised controlled design to investigate the acceptability and feasibility of providing a novel tele-rehabilitation balance training system (HOLOBalance) for community dwelling older adults at risk for falls. Older adults (age 65-80) who meet the inclusion criteria (e.g. independently living, no neurological conditions) will be recruited from falls services and from the wider community (via AgeUK) and will be randomly allocated to receive either a prescribed exercise programme delivered by: 1) the HOLOBalance tele-rehabilitation system or 2) an exercise booklet (The OTAGO Home Exercise Programme). Participants will be required to perform a series of prescribed exercises each day (duration of up to 30 minutes per day) for the entirety of the 8-week exercise programme. These exercises will be provided via the HOLOBalance tele-rehabilitation system (intervention arm) or by written instructions (control arm). Primary objectives for this study are to assess recruitment rate, compliance with exercise programmes (exercise diaries) and drop-out rates within the intervention group and a control group undertaking standard practice, home based balance rehabilitation (the OTAGO Home Exercise Programme) to explore whether HOLOBalance is acceptable to participants. Furthermore, acceptability to older adults will also be investigated via exit interviews performed within the HOLOBalance tele-rehabilitation intervention arm. Feasibility will be assessed by documenting adverse events (and SAE's), adverse device effects (and SADE's), deviations from protocol and feedback from treating clinicians. Implementation issues such as technology break down, service delivery and usability issues will also be documented. Secondary outcomes to explore trends for effectiveness will investigate performance of both groups at baseline and after the 8 week intervention across a range of outcome measures associated with balance function and falls risk, cognitive function, Physical activity and social participation, and subjective report of mobility and balance.
This study will use a socially assistive robot to deliver cognitive training in the form of a music (piano) learning intervention to socially isolated older adults with mild cognitive impairment.
The aim of this study is to determine the effects of krill oil supplementation on muscle mass in function in older adults. Half of the participants will receive krill oil supplements and the other half a placebo.
The study is an investigator-sponsored, prospective, multicenter, randomized, open-label study designed to compare efficacy and safety between bivalirudin and heparin in elderly patients with acute coronary syndrome undergoing elective percutaneous coronary intervention.
The menopause transition is associated with increased risk for weight gain and a shift toward storing fat in the belly region, which may increase risk for cardiovascular disease and diabetes. The study will determine whether the stress hormone cortisol contributes to this shift.
Study of efficacy of probiotic in older patients with multiple co-morbidites and constipation
Exercise can be beneficial for older adults by promoting health, delaying or reversing functional decline, reducing chronic disease risk, decreasing falls, increasing strength and stamina, improving ability to perform activities of daily living (ADL), and improving overall quality of life (QOL). Developing and implementing exercise programs for homebound older adults for whom traveling to routine clinic-based appointments may not be feasible or safe becomes critical. Homebound, older adults are at increased risk for recurrent hospitalization, use of emergency care, nursing home placement, and death. Indeed, one study shows patients had significantly higher risk of being admitted into a hospital or nursing home, higher mortality, and higher health care expenditures compared to those in a comparison group. The purpose of this pilot is to develop and implement a pragmatic and feasible intervention to improve physical functioning in older homebound adults with chronic mobility disability. Unfortunately, little is known about the feasibility and utility of pragmatic home-based exercise rehabilitation in older adults with severe mobility limitations. The investigators propose to develop and implement an intervention targeting functional limitations in this population with mobility disability. Our overall goals are to maintain and restore physical functioning and QOL for older, homebound adults. This research carries direct benefits for these patients as even modest improvements in disabled older adults may translate into significantly better QOL, reduce disability, minimize or reverse gradual declines related to serious chronic disease, resort functional independence, and increase community living capacity. Thus, the specified objectives of finalizing and implementing a sustainable home-based exercise program have practical implications for disabled older adults. Were homebound patients even slightly higher in terms of functional capacity, it could provide a partial degree of functional independence, impacting QOL for both patients and caregivers.
