Active clinical trials for "Sarcopenia"

RATIONALE The unique characteristic of our study lies in the attempt to reverse the functional impairment experienced by sarcopenic patients with hip fracture using nutritional intervention. What makes this study different from prior studies is that it will be conducted in a hospital setting, unlike most prior studies, which were conducted in a community setting. The association between muscle mass and strength, inflammatory indices, and functional impairment versus dependence and fragility will also be measured. HYPOTHESIS The hypothesis of our study is that nutritional intervention enriched in metabolites of essential amino acids (beta-hydroxy-beta-methylbutyrate) is effective for treating sarcopenia in elderly patients with hip fracture and improves functional level. OBJECTIVES Primary objective is to assess functional improvement after nutritional intervention in sarcopenic patients with hip fracture, as measured using Barthel index. Secondary objectives will include: 1) to show the relationship between metabolic and inflammatory indices and sarcopenia; 2) to show how sarcopenia and its treatment influence the risk of fall; 3) to show muscle mass improvement; 4) to show increased strength; 5) to assess mortality and morbidity. EXPECTED RESULTS The investigators expect to find that the supplemented group experiences throughout the study period a significant improvement in functional status (Barthel index), an increase in muscle mass, and a reduction in fat mass. An increased strength and a reduction in associated complications (falls) are also expected. The investigators hope to be able to show reductions in inflammatory indices and insulin resistance. To conclude, by improving muscle strength and mass the investigators expect to find a reduction in the disability and dependence of this population group.

The purpose of the study is to Test the effect of a dietary supplement beta-hydroxy-beta-methylbutyrate (HMB) with and without Vitamin D to prevent and reverse the losses of muscular strength and functionality in older adults. The second aim of the study is to determine if HMB and Vitamin D improves markers of bone turnover in adults aged 60 plus years. HMB is a dietary supplement that comes from the amino acid leucine. HMB is found in foods and is made in your body after you eat protein (meat). Subjects will be randomized to one of four dietary supplement groups and will participate in a 3-day per week exercise program for 12 weeks. Each exercise day will be about 60 minutes long consisting of strength training exercises utilizing Theraband® stretch cords and jumping. Subjects will consume the dietary supplement 2 times per day for 12 weeks. Tests will consist of the following: Measuring the strength of subjects' legs by using a Isokinetic Dynamometer Measuring body composition Measuring hand-grip strength using a hand-grip dynamometer Measuring functional mobility, balance and agility by the time it takes for you to rise from a chair, walk around a cone 8 feet in front of the chair and return to the chair (Up-&-Go Test Filling out questionnaires and having blood drawn for biochemical measurements. Testing will be performed at the beginning and at 4, 8 and 12 weeks.

The purpose of this study is to determine whether a higher-than-replacement dose of testosterone and finasteride can be combined to safely increase muscle strength in older men who have a low blood concentration of testosterone.

The purpose of this study is to determine whether consuming additional leucine during calorie restriction induced weight loss has beneficial or harmful effects on multi-organ (liver, muscle, adipose tissue) insulin sensitivity, colonocyte proliferation rates, the gut microbiome, muscle mass and function, and bone mineral density in obese, postmenopausal women.

Health effects of fish consumption have been demonstrated in epidemiological studies and in controlled intervention studies in a number of different population groups, however, randomized controlled studies on the effect of fish consumption in elderly are sparse. Many studies have focused on n-3 fatty acids instead of fish as a food and therefore, many health effects have only been related to the effect of n- 3 fatty acids. The elderly are a heterogeneous population group and therefore difficult to study. In order to reduce heterogeneity, it is advisable to focus on elderly with specific needs. Elderly who experienced a hip fracture can serve as a model for an advanced ageing process, as these patients typically experience a huge inflammatory response, immobilisation and a reduction in muscle mass. Increased fish intake is believed to have effects towards inflammation and a reduction in muscle mass. Therefore, we want to test whether increased fish intake can have positive health effects in elderly who experienced a hip fracture. Main hypothesis: Increased fish intake (salmon, cod, pelagic fish), in comparison to meat, will increase mobility, muscle strength and mobility in frail elderly. Objectives To evaluate the health effects of fish consumption in frail elderly The effect of a dietary intervention with fish on mobility, muscle mass and strength in elderly who experienced a hip fracture has not been shown before. To demonstrate the feasibility of dietary intervention in elderly We want to show that a dietary intervention with fish or control meals is feasible in elderly. The meals (4 portions of fish per week or control portions of meat) will be delivered to their homes. Description of work and role of participants This is a randomized clinical trial (RCT) on the effect of fish consumption on mobility in elderly who experienced a hip fracture. Elderly who experienced a hip fracture but were able to walk without support by a person before the fracture, will receive, after being randomized to two groups, fish or meat to be used in cold or warm meals at 4 days per week for a period of 16 weeks. Measurements will be taken at baseline (when patients have left the rehabilitation center), after 4 weeks and after 16 weeks. Measurements at 4 and 16 weeks after inclusion will be at their homes or in the outpatient clinic.

The primary goal of proposed investigation is to study the impact of oral glutamine supplementation on muscle mitochondrial and endothelial cell function measured mitochondrial energetics and vascular function using 31P magnetic resonance spectroscopy and optical spectroscopy (MRS/OS) among persons with moderate-severe CKD. The secondary objective is to describe the impact of oral glutamine supplementation on mitochondrial metabolic profile as well as inflammatory and oxidative stress biomarkers among persons with chronic kidney disease.

Sarcopenia is defined as the presence of low muscle mass and either decreased muscle strength or function. It is increasingly becoming a significant cause of frailty, loss of independence and physical disability in ageing western populations. Recent experimental evidence has revealed that skeletal muscle is particularly susceptible to damaging molecules that result in oxidative stress and that oxidative stress plays a prominent role in the development and progression of sarcopenia. The investigators have previously shown that the xanthine oxidase inhibitor allopurinol is able to abolish vascular oxidative stress and improve endothelial function in cohorts such as optimally treated chronic heart failure and chronic kidney disease. Recently, the investigators have also shown that allopurinol improves exercise tolerance and time to ST-depression in optimally treated coronary artery disease, suggesting that allopurinol could also exert its effects through ATP and/or oxygen sparing mechanisms. Therefore, we propose a randomised double blind placebo-controlled parallel group trial of allopurinol in patients with primary sarcopenia using MR-spectroscopy and Flow Mediated Dilatation to investigate the possible mechanisms that underlie this exciting possibility

The purpose of this study is to determine whether consuming additional protein during calorie restriction induced weight loss has beneficial or harmful effects on multi-organ (liver, muscle, adipose tissue) insulin sensitivity, colonocyte proliferation rates, the gut microbiome, muscle mass and function, and bone mineral density in obese, postmenopausal women.

The study aims to determine the effects of testosterone on muscle function, mobility, activities of daily living and overall quality of life

Investigators plan a prospective cohort study with an adaptive design based on physical function status. The design will involve tracking the number of women recruited with physical function impairment and those without any functional impairment. Investigators aim to recruit similar numbers of women in each group. If investigators find unequal numbers, they will adapt recruit strategies based on a woman's functional status.
