Active clinical trials for "Sarcopenia"

Sarcopenia is defined as a decrease in muscular strength and muscle mass, accompanied by a decrease in physical performance. Seniors might develop sarcopenia because of a decreased physical activity and a decreased protein intake. Many patients also develop sarcopenia after a long stay in an intensive care unit. Protein intake is very important when treating sarcopenia. However, meeting the protein requirements at home proves difficult. Oral dietary supplements, given in addition to the other known recommendations, might provide a solution. This study will assess the efficacy of the oral dietary supplements for the treatment of sarcopenia.

Immobilization in general internal medicine inpatients is a major contributor to morbidity and mortality. Goal-directed mobilization (GDM) may improve mobility. The aim of this study is to assess, if GDM increases physical activity (DEMMI score) during hospitalization and improves quality of care until 3 months after hospitalization.

Vitamin D deficiency is proposed to be prevalent in community-dwelling older adults, with prevalence substantially higher among older adults in residential care facilities. Musculoskeletal health is compromised in older vitamin D deficient individuals and alongside frailty, sarcopenia and osteoporosis associated with ageing, affected individuals are at increased risk of falls and fractures. Vitamin D supplementation is an effective intervention for fall prevention and, along with calcium supplementation, in fracture risk reduction in institutionalised older adults. Thus, monitoring vitamin D status and treating deficiency among older adults in residential care facilities may limit the substantial economic burden associated with falls/fractures in this population. The vitamin D status of older adults in residential care facilities in Northern Ireland (NI) is currently unknown, therefore, the aim of this pilot study is to determine the vitamin D status of this cohort of the population, and to define factors which may influence vitamin D status, including body mass index (BMI), mobility out-of-doors, medication use, dementia and diet. Vitamin D status will be determined via the measurement of 25-hydroxyvitamin D using liquid chromatography-tandem mass spectrometry (LC-MS/MS). In addition, biomarkers associated with vitamin D metabolism will be measured including calcium, albumin, creatinine, urea, bone turnover markers and parathyroid hormone. Factors that may affect vitamin D status will be assessed using a health and lifestyle questionnaire and dietary vitamin D intake will be estimated via analysis of the menus in the residential care facilities. Vitamin D supplementation practices in these facilities will also be assessed via analysis of drug prescription records, focusing on differences between residents who have/have not suffered a fracture. Physical measures such grip strength, timed up and go test and T-score measurement via Achilles ultrasound machine will be taken. This study will provide data on the prevalence of vitamin D deficiency in older adults in residential care facilities within NI and identify factors that predispose residents to increased risk of deficiency. Dissemination of these findings, along with analysis of current supplementation practices, will help practitioners to develop a strategy to identify those residents with vitamin D deficiency/insufficiency and thus requiring supplementation ultimately improving health and well-being. This study will also inform the design of a larger study to investigate vitamin D status, supplementation and musculoskeletal health in older adults in residential care facilities within Northern Ireland, providing important information that will ultimately contribute towards reducing falls and fractures within this population.

The general hypothesis is that administration of testosterone to healthy, older men for 52 weeks (1 year) following a cycle of 4 weeks of testosterone administration and 4 weeks without testosterone (i.e., monthly cycled regimen) will provide the same gains in muscle strength, muscle mass, and bone density as standard of care (SOC), continuous administration of testosterone for 52 weeks.

This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of Ursolic Acid of Loquat Extract for treatment of muscle function improvement with relatively health adults. 54 subjects received 500 mg of Loquat Extract per day or a placebo for 12 weeks.

The goal of this study was to evaluate the effect of detraining in the components of physical aptitude of people living with HIV/Aids (PVHA).

Several trials have found that nutritional supplementation can elicit an increased rate of skeletal muscle protein synthesis following a single bout of exercise in both young and older individuals. However, there have been no studies that have investigated if nutritional supplementation and exercise can cause a sustained increase in physical functioning and fat free mass, particularly in older adults with functional limitations. This study will compare the effects of a nutritional supplement versus a placebo on exercise training induced changes in physical functioning older adults who are at risk for mobility disability.

Rationale: Age related muscle loss (sarcopenia) is assumed to be related to the impaired postprandial muscle protein synthetic response to protein and/or amino acid administration in the elderly vs the young. Co-ingestion of carbohydrate increases post-prandial insulin secretion. Insulin affects skeletal muscle blood flow and may therefore affect substrate availability and postprandial muscle protein synthesis. However, it is unclear whether the response to the combined intake of protein and carbohydrates is different in elderly compared to young subjects. Hypothesis: Adding carbohydrate to a bolus of protein represents an effective strategy to overcome the impaired postprandial muscle protein synthesis in the elderly. Objective: The primary objective of the study is to investigate whether carbohydrate co-ingestion augments the in vivo postprandial muscle protein synthetic response after protein ingestion and whether this response is different between young and elderly subjects. The secondary objective of the study is to assess the effect of carbohydrate co-ingestion on insulin levels and microvascular perfusion in young and elderly subjects. Intervention: The intervention consists of a single test day during which the subjects will receive a drink containing 20 gram intrinsically labelled casein with or without 60 gram carbohydrates. In addition, continuous intravenous tracer infusions of labeled amino acids will be administered. During the test day 18 plasma samples and 4 muscle biopsies will be collected over a period of 8½ h. Furthermore, muscle skeletal blood flow will be estimated using sidestream darkfield imaging (SDF) in sublingual position.

The goal of this observational study is to evaluate in elderly patients for the frequency of sarcopenia and its relationship with mortality in a university hospital. The main questions it aims to answer are; What is the frequency of sarcopenia in elderly patients at emergency department? Is sarcopenia associated with mortality in an elderly patient admitted to the emergency department?

Juvenile idiopathic arthritis (AJI), is a frequent inflammatory disease in children, characterized by pain, arthritis, and deformities. Chronic inflammation leads to physical inactivity and can be associated with muscle weakness around affected joints, low bone strength, and mass(3). To our knowledge, no study has focused on the prevalence of sarcopenia in JIA and the data on the muscle disorder are lacking. The purpose of the present study is to detect sarcopenia and identify associated factors in children with JIA
