Filter by:The investigators recently published significant associations between circulating gut bacteria-related metabolites with lean and skeletal muscle mass and with measures of physical function in older adults, evidence that suggests a role for gut bacteria on the maintenance of these outcomes. To date, studies aimed at identification of associations between gut bacteria with lean mass or with specific measures of physical function have yet to be reported. Accordingly, the over-arching hypothesis is that gut bacteria are associated with, and are causatively involved in mechanisms that underlie the maintenance of lean mass and physical function in older adults. Results obtained from the proposed study are intended as the basis for future studies aimed at targeted modulation of the gut microflora, which may be a novel and innovative means for improving lean mass and physical function, and for addressing the public health priority of healthy aging in older adults.
Sarcopenia is defined as a loss in skeletal muscle mass and function (strength and/or performance). There is a high prevalence in elderly and in patients with cancer. Several mechanisms are known to explain sarcopenia (inflammation, neurodegenerative process, hormonal disorders, lack of exercise, malnutrition). The consequences were analysed in several studies where sarcopenia appeared to be an independent factor of mortality, and associated with cancer-related fatigue, nosocomial infections, cardio-vascular diseases, and chemotherapy toxicities. Diagnosis is based on the measure of the muscle mass performing an abdominal computed-tomography (CT) scan, and on the measure of the muscle strength using the handgrip test with a "Jamar®" hydraulic hand dynamometer. CT scan is more invasive and less easy to reach than handgrip test. This test is used to be performing in elderly but not in cancer patients having chemotherapy. Present prospective study explored the feasibility of systematic handgrip strength testing and short-term changes in muscle strength in digestive cancer patients treated by chemotherapy.
The purposes of this study are 1. To explore effect of sarcopenia on recovery of post stroke hemiplegia 2. To explore the effect of stroke on sarcopenia and relationship between the degree of sarcopenia and respiration and swallowing function 3. To quantify and qualify post stroke loss of muscle mass 4. To validity the use of echointensity and elastography in evaluation of sarcopenia. By reaching the above list purposes, sarcopenia can be viewed as one of serious post stroke complications that is closely related to worth functional outcome, thereby emphasizing the importance of evaluation of sarcopenia as well as its prevention.
The investigators determined effects of 8-week dietary protein intake in mixed meals with uneven or even consumption pattern on the metabolic outcomes of whole-body net protein synthesis and muscle protein synthesis in older participants.
Cancer 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.
The aims of this study are to establish the cohort of elder population based on parameters of health-related fitness, body compositions, blood biochemistry, blood biomarker, balance, quality of life, and musculoskeletal ultrasonography; and to evaluate the association between fitness parameters and disease incidence with those data.
The primary aim of this study is to improve both physical fitness and sarcopenia of patients with ESLD who are potentially eligible for liver transplantation through a 12-week physical training program. Secondary aims will focus on changes in anthropometrics, body composition, quality of life, and metabolic profile. This is a randomized clinical trial including 50 patients, with half allocated to the active group (physical training program) and half to standard of care.
Uraemic sarcopenia is complex, and progressive . As older persons are particularly susceptible to renal failure and this accelerates the physiological muscle wasting in this patient group. Hence sarcopenia is an important factor of functional impairment in elderly patients suffering from chronic kidney disease. On the other hand, overweight has become increasing common in dialysis patients, and is paradoxically reported to be associated with better survival. It remains unclear if adipose tissue in overweight in elderly dialysis patients is a source of proinflammatory mediators, which could contribute to protein-energy wasting (PEW), cardiovascular disease, and increased mortality. This study attempts to explore the prevalence of Sarcopenic Obesity (SO) in a cohort of hemodialysis patients with a more well defined criteria. In addition, this study aims to examine the association between sarcopenia and SO with metabolic and cardiovascular risk factors in these patients.
The purpose of the study is to investigate if an increased protein intake, in the form of a protein-enriched, milk-based supplement, can enhance the beneficial effect of resistance training, offered during hospitalization and 12 weeks post discharge, in older patients. This will in part be evaluated from measures of muscle strength, muscle mass and physical functioning. Also, the study population's acceptance of the intervention product will be assessed along with measures related to 'cost-effectiveness'. A sub-study will be performed in a sub-group (n=30) to investigate if bio-impedance analysis (BIA) correlates with Dual-Energy X-ray absorptiometry (DXA) at single time points, and to see if it is possible to track changes in lean body mass. In addition, the reliability of the bio-impedance analyzer will be evaluated. Also, the prevalence and classification of sarcopenia will be assessed at baseline, and correlations to nutritional status will be investigated (n=120).
The purpose of this project is to investigate the age-related differences in force-velocity muscle characteristics during isolated knee extensions variable in speed and load, during cyclic movements on a usual and recumbent bike variable in speed and velocity development and a functional test battery with healthy participants aged between 20-80 years.
