Filter by:The aim of this study is to examine the performance of determining the sarcopenia by anthropometric measurements (mid-upper arm circumference and calf circumference) added to the SARC-F questionnaire developed as a screening tool for the risk of sarcopenia in the community-dwelling older adults. The risk of sarcopenia of the individuals over 65 years of age who applied to the Geriatrics Department of Ege University Medical Faculty Hospital Internal Diseases Department. was determined by the SARC-F questionnaire, muscle mass was established by bioelectrical impedance analysis, muscle strength was assessed by handgrip strength, physical performance was assessed by a 4-meter walking test and presence of malnutrition was assessed with an MNA-long form. For the diagnosis of sarcopenia; old (EWGSOP 1) and revised (EWGSOP 2) diagnostic criteria of Sarcopenia Study Group in Elderly Individuals of the European Union Geriatric Medicine Association were used. New parameters were obtained by adding calf circumference (SARC-CC) and mid-upper arm circumference (SARC-MUAC) measurements were added separately and together (SARC-CC-MUAC) to the SARC-F. For the calf circumference cut-off points of <31 cm and <33 cm and for the mid-upper arm circumference cut-off points of <25 cm and <31 cm were used for the sensitivity and specificity analyses.
Sarcopenia is the major health concern and common consequence of COVID-19 in the aging population. Moreover, this clinical condition has not been considered in usual physical rehabilitation practice, and its optimal protein requirement in food is not well defined, which requires a meaningful study in this field. The reports of this trial would deliver the latest evidence and proper guidelines for the prescription of physical exercises and also provide an optimal dietary plan in sarcopenia patients with COVID infection. Objective: To find and compare the clinical and psychological effects of integrated physical training with a high protein diet versus a low-protein diet in community-dwelling COVID-19 asymptomatic older adults with Sarcopenia symptoms.
To analyze the effects of a high intensity exercises program by intervals on sarcopenia, active aging and oral microbiota in older adults.
Muscle failure (sarcopenia or dynapenia) is a factor of frailty and therefore, ultimately, of loss of autonomy in the elderly. Currently, no biomarker of muscle failure has a high sensitivity, specificity and positive predictive value. Several results, although preliminary, suggest that metabolomics could facilitate the early identification of frail patients, allowing the implementation of primary prevention strategies. Untargeted high-resolution metabolomics analysis would identify discriminative biomarkers and biological mechanisms associated with frailty. Finally, the hypothesis that metabolic signatures can be identified as risk factors for the development of age-related dynapenia should be tested in a longitudinal design.
Rationale: Food intake stimulates muscle protein synthesis rates. The magnitude of the anabolic response to feeding forms a key factor in regulating muscle mass maintenance. Ingestion of animal-derived proteins generally leads to a greater stimulation of muscle protein synthesis when compared to the ingestion of plant-derived proteins. What is often neglected is that the anabolic properties of protein isolates do not necessarily reflect the anabolic response to the ingestion of the whole-foods from which those are derived. This discrepancy is due to the presence or absence of other components normally found within whole-food matrices, which influence protein digestion and amino acid absorption from animal based and plant based protein sources. A rapid and robust post-prandial release of food-derived amino acids is of particular relevance for older individuals, who typically show a blunted muscle protein synthetic response to feeding Objective: To compare the post-prandial muscle protein synthetic response following ingestion of a whole-food meal (560 kilo calorie (kCal); ~36 g protein total, ~0.45 g/kg body weight) containing ~100 g lean ground beef (~30 g protein) versus the ingestion of an isonitrogenous, isocaloric whole-food meal containing only plant-based protein sources (561 kCal; ~36 g protein total) in vivo in healthy, older men and women. Study design: randomized, counter-balanced, cross-over design, researchers and participants are not blinded, analysts are blinded. Study population: 16 healthy older (65-85 y) men and women (1:1 ratio of men:women) Intervention: Participants will undergo 2 test days. On one test day participants will consume a whole-food meal containing meat as the primary source of protein (~36 g, ~0.45 g/kg body weight). On the other day, participants will consume a whole-food meal containing only plant-based foods as the source of protein (~36 g or ~0.45 g/kg body weight). In addition, a continuous intravenous tracer infusion will be applied, and blood an muscle samples will be collected in order to assess the muscle protein synthetic response. Main study parameters/endpoints: The primary endpoint will be mixed muscle protein synthesis rates over the full 6h post-prandial period following meal ingestion.
Frailty and sarcopenia are two age-related syndromes which can result in adverse health-related events. The combination of both is more predictive of mortality than either condition alone. These conditions can be reversed through an early detection and appropriate interventions. Nevertheless, scientific community highlights the lack of cheap, portable, rapid and easy-to-use tools for detecting frailty and sarcopenia in combination. The aim of this study is to validate an iPhone App to detect frailty and sarcopenia syndromes in community dwelling older adults. This is a protocol study of a retrospective diagnostic test accuracy study which will include at least 400 participants older than 60 years recruited from elderly social centers of Murcia city. Researchers will recollect data of health status, dependency, cognitive status, and functional capacity of the participants. The index test will consist in the measurement of muscle power exerted during a single Sit-to-stand through an App (iPhone), combined with calf and mid-upper arm circumference. The reference standard will be frailty syndrome and sarcopenia assessed according to Fried's phenotype and to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) (2019) recommendations, respectively. Sensitivity, specificity, positive predictive value, negative predictive values, and area under the curve will be reported.
Sarcopenia has been defined as a disease which presented as low muscles strength, low muscle quantity or quality and low physical activity. The prevalence of sarcopenia is increasing with the age and it is also included in one of geriatric syndromes. Several criteria have been mentioned for diagnosis of sarcopenia, such as European Working Group on Sarcopenia in Older People (EWGSOP)、Foundation for the National Institutes of Health Biomarkers Consortium Sarcopenia Project (FNIH) and Asian Working Group for Sarcopenia (AWGS). In European, the prevalence rate of sarcopenia is 9.25-18%; 5-7% Canadian and 14.4% Taiwanese elders have been diagnosed as sarcopenia, respectively. The sarcopenia has been found its relationship with adverse outcomes of fall down, fracture, disability, and death. The cytokines and decline in anabolic hormones play a role in the pathogenesis of sarcopenia. Tai Chi exercise is one of Qigong and well-popular in Chinese population, and is helpful to integration of body movements. Tai Chi exercise is less complicated and emphasized people's awareness of self-care which presented the relationship between human and nature. Tai Chi exercise could improve muscle performance, balance and have the benefit for fall down prevention in the elders and patients with frailty. Furthermore, Tai Chi has been found that it also could improve the muscle power and power strength in sarcopenic elders by team training. Furthermore, immune makers of inflammation process have been noted their diminishments by Qigong intervention. The aim of this study is to investigate the effect of Tai Chi exercise in sarcopenic elders through practicing at home. The differences of muscles strength, muscle quantity or quality and physical activity after interventions would be recorded and analyzed. The cytokines related to the sarcopenia process would also be sampled.

Rationale: Aging is accompanied by impairments in the sensitivity of skeletal muscle tissue to respond to the anabolic properties of protein feeding, which is suggested to result in age-related loss in muscle mass. Adequate muscle perfusion capacity is essential for muscle mass maintenance, as it determines the rapid delivery of amino acids, nutrients and growth factors to the muscle fiber, thereby stimulating muscle protein synthesis. However, muscle perfusion capacity declines with increasing age. Hence, improving muscle perfusion may be key to augment the sensitivity of senescent muscle following protein feeding in older adults. Although exercise training is an effective way to improve muscle perfusion capacity, there are a number of patient groups that find exercise training difficult to achieve. Hence, alternative strategies need to be developed to improve muscle perfusion capacity. Passive heat treatment (PHT) has been associated with various health benefits in older adult populations, including improved blood pressure, cardiovascular disease risk, and metabolic health. In addition, PHT has been shown to increase muscle fiber capillarization in healthy young adults. However, whether such an intervention improves muscle perfusion capacity, and enhances the anabolic response of skeletal muscle following food ingestion in older adults is unknown. Objective: To assess the impact of an 8-week passive heat treatment intervention on skeletal muscle fiber capillarization/perfusion capacity and post-prandial muscle protein synthesis rates in healthy older adults. Study design: single arm, within subject study design Study population: 14 healthy older (65-85 y) men and women. Intervention (if applicable): Participants will be subjected to an 8-week (3 x pw) PHT, by means of infrared sauna bathing, intervention. Before and after the PHT intervention the participants will undergo one test day during which blood pressure, body composition, physical function and muscle strength will be assessed. In addition, before and after the PHT intervention period subjects will be complete a 'whole-meal test day' during which the muscle protein synthesis and perfusion capacity response will be evaluated following the ingestion of a whole food meal. Basal and post-prandial muscle protein synthesis and perfusion capacity will be assessed by a continuous infusion of labelled amino acids combined with contrast-enhanced ultrasound measurements. Blood and muscle samples will be collected in order to assess the muscle protein synthetic response. Main study parameters/endpoints: The primary outcome will be post-prandial muscle protein synthesis rates following meal ingestion.
Sarcopenia and malnutrition are two geriatric syndromes that are frequently seen in the elderly and have multifactorial etiology and severe clinical effects. However, the results vary widely due to the many methods and criteria used in the diagnosis and prevalence rates of both syndromes. In this study, it is aimed to investigate the relationship between the GLIM (Global Leadership Initiative on Malnutrition) criteria and various sarcopenia levels, which are newly defined worldwide and have the widest spectrum so far in describing malnutrition.
