The Presence Of Sarcopenia In Patients With Knee Osteoarthritis
SarcopeniaOsteoarthritisOsteoarthritis (OA) is one of the most common joint disorders worldwide . The knee is the most common symptomatic joint in osteoarthritis. In this study, we evaluated the presence of sarcopenia multidimensionally in patients with knee osteoarthritis (OA) using clinical, ultrasonographic and biochemical parameters, and in this respect, it was aimed to investigate the relation between OA and sarcopenia and to identify the most practical, easily accessible and inexpensive method for investigating sarcopenia.

Gripwise® Versus JAMAR®
Age-Related SarcopeniaIt is recommended to screen ageing patients for sarcopenia, due to the increased risk of morbimortality if detected positive. According to the consensus of the European Working Group on Sarcopenia in Older People, the diagnosis of sarcopenia is based, among other things, on grip strength measurement. Our study will compare the performance of the new GRIPWISE digital device with the mechanical dynamometer JAMAR, the gold standard currently used to assess the grip strength. We propose to evaluate it in an elderly hospitalized population where the prevalence of sarcopenia is likely to be high due to the high prevalence of various chronic illness, notably oncological and cardiological ones. This cross-sectional study will include 348 patients.

Impact of Sarcopenia Using an Easy Psoas Area Measurement
SarcopeniaThe purpose of this study is to compare the post-operative course in patients suffering from sarcopenia who had colorectal surgery for cancer. Our primary outcome is the comparaison of the length of hospital stay in sarcopenic and non sarcopenic patients.

Validity of an App to Detect Frailty and Sarcopenia Syndromes in Elderly
SarcopeniaFrailty Syndrome3 moreFrailty 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.

Role of the Gut Microbiome on Lean Mass and Physical Function in Older Adults
SarcopeniaThe 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.

IGF-1, Sarcopenia and Mortality: a Cohort Study in Patient With Cognitive Impairment
Cognitive ImpairmentInsulin-like Growth Factor 1Insulin-like growth factor 1 (IGF)-1 is an important neuromyotrophic hormone. Disregulation of this hormone has been reported to influence the genesis of cognitive impairment and dementia in the elderly patients. We analyzed the possible link between IGF-1 and risk of Sarcopenia and Mortality in a cohort of elder patients with cognitive impairment.

Is Gait Speed and Sarcopenia Prognostic in Chronic Respiratory Disease?
Chronic Obstructive Pulmonary Disease and Allied ConditionsThis study aims to assess usual walking speed (4-metre gait speed) and markers of sarcopenia predict mortality in patients with chronic respiratory disease.

Blood Flow, Muscle Regeneration and Sarcopenia
SarcopeniaDue to the rapid aging of the population, sarcopenia is among the greatest challenges facing the health care system over the next quarter century. This age-related loss of skeletal muscle mass and strength directly contributes to the incidence of functional disability, thereby reducing independence and quality of life for the elderly. Despite increasing efforts to combat sarcopenia, its etiology remains incompletely described. Subsequently, limited progress has been made in developing comprehensive preventative and therapeutic strategies to combat the problem. A decreased ability to regenerate skeletal muscle fibers through the donation of skeletal muscle stem cells (satellite cells) is thought to contribute to sarcopenia. However, the upstream physiological mediators that regulate this impairment are poorly delineated. Reduced muscle blood flow in advanced age appears to be a significant factor in reducing skeletal muscle regenerative capacity, but few data exist to confirm this hypothesis. Thus to test this hypothesis we aim to conduct a translational pilot trial which examines regeneration in both young and old adults. Furthermore, we aim to determine if muscle blood flow and satellite cell number are associated with muscle function. The central hypothesis of this proposal is that age-related declines in skeletal muscle angiogenesis and perfusion are significant causal factors in age-related losses of skeletal muscle mass. The specific aims and hypotheses of the project are as follows:

The Prevalence of Malnutrition and Sarcopenia in Swiss Rehabilitation Settings
MalnutritionSarcopeniaThe aim of the study is to identify the prevalence of malnutrition and sarcopenia in patients admitted in Swiss rehabilitation centers. Furthermore, the aim is to investigate the changes of selected malnutrition and sarcopenia parameters over the length of the rehabilitation stay.
