Effect of Exercise and Protein Supplementation on Muscle Function in Patients With Hemodialysis...
SarcopeniaSarcopenia can be easily observed in patients with hemodialysis. However, there were few studies on the precise concept and diagnostic criteria for sarcopenia in patients with hemodialysis. The investigators have already recognized the sarcopenia-associated mortality and morbidity in patients with hemodialysis. However, intervention studies on hemodialysis patients with sarcopenia have not been conducted until now. Here, The investigators aim a pilot study to evaluate the effectiveness of the combined exercise and nutrition intervention for sarcopenia in patients with hemodialysis. This is a prospective study with 60 patients with hemodialysis who were diagnosed as sarcopenia or frailty in our previous cohort study. Combined intervention will consist of resistance exercise and nutritional supplementation for 12 weeks. The primary outcome of this study is muscle mass and handgrip strength after 12 weeks' intervention. All functional outcomes will be measured at 0, 12, and 24 weeks after intervention. The data will be analysed using the intention-to-treat principle.
Feasibility of a Novel Resistance Exercise in Individuals With Osteoporosis
OsteopeniaOsteoporosis2 moreThe aim of the 6 month randomized controlled trial is to investigate the feasibility of a novel progressive muscle resistance exercise in postmenopausal women with low bone mass.
Does Human Skeletal Muscle Possess an Epigenetic Memory of Testosterone?
Healthy AgingAge-Related Sarcopenia1 moreThis project's primary aim of this double-blinded, randomised, placebo-controlled trial is to investigate whether short-term testosterone administration +/- resistance exercise training induces a muscle memory response that can lead to longer-lasting benefits in aged human skeletal muscle. The investigators will provide older men with the anabolic hormone, testosterone or placebo, with or without resistance training, followed by a period of testosterone abstinence and detraining, followed by a subsequent repeated period of resistance training (retraining). This will help determine if earlier encounters with short-term testosterone administration can be "remembered" and if adaptation to later retraining can be enhanced as a consequence of encountering testosterone earlier.
Muscle Stem Cell Quality in Atrophy
Muscle WeaknessAtrophy5 moreThe goal of this clinical trial is to compare the quality of mesoangioblasts isolated from various patient groups suffering from muscle atrophy. This study includes cancer cachexia and muscle-impaired elderly and a control group of the same age. The quality will be defined on these following outcomes: The number and distribution of the mesoangioblasts in a muscle biopsy to define if there are sufficient mesoangioblasts to start a culture. The proliferation capacity to define if we can culture them the numbers required for systemic treatment. The myogenic capacity to define if the mesoangioblasts are sufficiently capable to generate muscle fibres. Participants will: Undergo a muscle biopsy (needle biopsy or rest material from surgery, ~50mg) Donate blood (~20 ml) Fill in SARC-F questionnaire (evaluate sarcopenia score) Fill in SQUASH questionnaire (evaluate physical activity of previous week) Researchers will compare groups (muscle-impaired elderly vs control; cancer cachexia vs control) to see if there is a difference regarding quality. These results will define the potential of autologous mesoangioblast therapy within these groups.
Functional Changes and Power Training in Older Women.
SarcopeniaMuscle WeaknessExtending quality of life and attenuating functional decline is paramount in older adults. This study investigates the effects of low-intensity power-training in older women and its effects on functional outcomes.
Angiotensin Receptors and Age Related Mitochondrial Decline in HIV Patients
HIVAging2 moreThis study is designed to evaluate specific factors in mitochondria that may precipitate premature aging and physical weakness in HIV patients. Angiotensin receptors 1 and 2 (AT1R and AT2R) are found in virtually every cell type. This study will evaluate how the relationships among these receptors in immune and skeletal muscle cells change with HIV, and how these changes might trigger mitochondrial dysfunction, declines in muscle strength, and cellular decline in people living with HIV.
Postacute Sarcopenia: Supplementation With β-hydroxyMethylbutyrate After Resistance Training
SarcopeniaA randomized, double-blind, placebo-controlled, parallel study to assess the effects of β-hydroxymethylbutyrate (β-HMB) combined with a resistance training program, after an acute process in older patients with sarcopenia in terms of muscle mass, muscle strength and physical performance. Treatments compared will be β-hydroxymethylbutyrate (β-HMB) with a resistance training program or placebo with a resistance training program.
Omega-3 Supplementation in Cervix Cancer Patients Undergoing Chemoradiotherapy
SarcopeniaCancer cachexia is a complex metabolic process affecting up to 80% of patients suffering from an advanced-stage cancer. Moreover, 20 to 40% of all cancer deaths are caused directly by cachexia. Recently, omega-3 fatty acids have gained interest for their beneficial effects in cancer cachexia. Moreover, nutritional supplementation enriched with omega-3 could potentially maintain body weight in cancer patients undergoing intensive treatment. The investigators aims in this study is to evaluate the effect of omega-3 supplementation on body composition, functional capacity, inflammatory profile and quality of life in cervix cancer patients undergoing chemoradiotherapy.
Nutritional Intervention for Age-related Muscular Function and Strength Losses-Study 2
SarcopeniaMen and women lose muscle mass and strength with age. Loss of muscle mass and strength is accompanied by a loss of muscle function which can lead to diminished quality of life and more importantly can lead to serious fall requiring medical treatment. The investigators hypothesize that the combined supplements of Calcium-HMB and Vitamin D will lead to decreased falls and to improved quality of life (QOL) for older adults. The investigators further hypothesize that the addition of a modest exercise regimen to these supplements will enhance the synergistic effects of both Calcium-HMB and Vitamin D. Subjects will consume the dietary supplement 2 times per day for 12 months. Tests will consist of the following: a) strength of subjects' legs and elbow by Isokinetic Dynamometer; b) body composition; c) hand-grip strength by hand-grip dynamometer; d) functional mobility, balance and agility (Get-Up and Get-Up-and-Go tests); e) filling out questionnaires; and g) having blood drawn for biochemical measurements. Testing will be performed at the baseline (0 months) and at 3, 6, 9, and 12 months.
The Effect of 6 Months of Local Vibration Training in Institutionalized Elderly
