Filter by:Obesity is highly prevalent in older adults and is a major cause of sarcopenia and disability in older adults. Although exercise can counteract the effects of obesity and sarcopenia, many have difficulty adhering to an exercise program and the benefits of exercise are variable. Therefore, there is an urgent need to test novel pharmacologic interventions to prevent disability and loss of independence. Oxytocin is a pituitary hormone released during parturition and lactation that is also known to suppress appetite in rodents and humans; and, recent small studies have found that intranasal oxytocin reduces body weight in adults. We propose a pilot study of intranasal oxytocin as a novel approach to promote weight loss and increase muscle mass in older subjects with sarcopenic obesity.
The proposed research is designed to identify the mechanisms that can accelerate loss of muscle size, strength and physical function in type 2 diabetes and with hospitalization in older persons. About ⅓ of older Americans have type 2 diabetes, and about ⅓ of the hospitalizations in the USA involve persons older than 65 year of age. The proposed research is relevant to the part of NIH's mission that pertains to development of the fundamental knowledge that will improve health and reduce the burdens of disability, because this work will provide the fundamental evidence to identify new targets for the development of innovative treatments to slow down muscle loss and disability in our aging society.
The prevalence of sarcopenia is high in many organ pathologies such as COPD, but remains little studied in acute respiratory failure. Sarcopenia is a health problem representative of frailty, loss of autonomy and decreased muscle strength. The frequency and evolution of sarcopenia is unknown in patients having chronic bronchic obstruction with exacerbation.
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).
In line with improvements in oncologic outcome for patients with esophageal cancer, the attritional impact of curative treatment with respect to functional status and health-related quality of life (HR-QL) in survivorship is increasingly an important focus. Functional recovery after surgery for esophageal cancer is commonly confounded by anorexia and early satiety, which may reduce oral nutrient intake with consequent malnutrition and weight loss. One in three disease-free patients has more than fifteen percent body weight loss at three years after esophagectomy. The ESPEN Special Interest Group on cachexia-anorexia in chronic wasting diseases has defined sarcopenia as skeletal muscle index (SMI) of ≤39 cm2/m2 for women and ≤55cm2/m2 for men, while similar cut-off points have been validated in upper gastrointestinal and respiratory malignancies (less than 38.5 cm2/m2 for women and 52.4 cm2/m2 for men). The European Working Group on Sarcopenia in Older People (EWGSOP) additionally recommends that assessment should also include determination of muscle function, for example gait speed or grip strength, where possible. The presence of sarcopenia is associated with increase treatment-associated morbidity, impaired HR-QL, reduced physical and role functioning, and increased pain scores in older adults. In addition, a previous longitudinal study demonstrated that the decline in HR-QL over a six year period in older adults was accelerated in the presence of sarcopenia. As such, sarcopenia may represent a modifiable barrier to recovery and subsequent retention of HR-QL and functional status, and may reinforce a persistent illness identity, among patients following potentially curative treatment for esophageal cancer.
Background. In advanced chronic kidney disease (CKD), multiple metabolic and nutritional abnormalities may contribute to the impairment of skeletal muscle mass and function thus predisposing patients to the condition of sarcopenia. Herein, we aim to investigate the association of uremic toxins and sacropenia. In addition, the prevalence and mortality predictive power of sarcopenia, defined by different methods, in a cohort of hemodialysis patients. Methods. We plan to evaluate 300 HD patients. Sarcopenia was defined as reduced muscle function assessed by handgrip strength (HGS <30th percentile of a population-based reference adjusted for sex and age) plus diminished muscle mass assessed by different methods: (i) midarm muscle circumference (MAMC) <90% of reference value (A), (ii) muscle wasting by DEXA (B) and (iii) reduced skeletal muscle mass index (<10.76 kg/m² men; <6.76 kg/m² women) estimated by bioelectrical impedance analysis (BIA) (C). Serum levels of 3 established uremic toxins such as indoxyl sulfate, p-cresol and hippuric acid will be measured. Besides, various relevant inflammatory markers will also be assessed. Patients will be followed for up to 3 years for all-cause mortality.
Investigators plan a prospective cohort study with an adaptive design based on physical function status. The design will involve tracking the number of women recruited with physical function impairment and those without any functional impairment. Investigators aim to recruit similar numbers of women in each group. If investigators find unequal numbers, they will adapt recruit strategies based on a woman's functional status.
The SARA-OBS is a single arm phase 2 clinical trial, with no investigational product and no therapeutic intervention that will be conducted in three European countries, (Belgium, France and Italy), and in the US. 300 community dwelling older adults (men or women≥65 years) reporting loss of physical function and at risk of mobility disability, will undergo mobility functional evaluation and Dual-energy X-ray Absorptiometry DXA scan for body composition determination twice, at six-month interval. Participants aged ≥ 65 years complaining of poor physical function will be selected to perform SPPB (Short Physical Performance Battery)tests. Those with SPPB scores ≤ 8/12 will be selected to perform body composition analysis with DXA Scan. Participants with ALM/BMI < 0.789 in men and 0.512 in women will be included. The investigational phase will comprise two main visits: the inclusion visit and the 6-month visit. Both the 6-minute walk distance test and the 400-metre walking test will be administered at the main visits. Patient Reported Outcomes (PROs) will be completed by the patients at the same visits.
Rationale: There is increasing evidence that obesity may be a risk factor for frailty in the elderly. Obesity favors a state of chronic inflammation and insulin resistance, involves a fatty infiltration of the muscle and an increased cardiovascular risk and, in addition, obese people usually perform less physical activity. All this favors the loss of mass and muscular function (sarcopenia), a key component of the fragility and the functional deterioration. Objectives: To evaluate the effectiveness of a multimodal intervention to lose weight in the prevention of frailty in obese elderly people, as well as to know the main mechanisms involved in the frailty process. Methodology: Design: Controlled, randomized, open-label clinical trial with two parallel intervention arms and 2 years follow-up. Study population: People between 65 and 75 years of age, obese (BMI ≥30), without criteria of fragility and living in the community. Study intervention: multimodal and personalized intervention with the support of a "personal trainer" that has two main axes of action: a) diet: assessment of nutritional status and nutritional requirements and establishment of personalized nutritional plan with monthly dietetic controls and b) physical exercise: a multi-component physical exercise program that will include aerobic exercise and strengthening, balance and flexibility exercises as well as a weekly group session of health education, during six months. Main outcome measures (to be evaluated annually for 2 years): Fragility (according to the L Fried criteria) and Sarcopenia (according to the criteria of the European Working Group on Sarcopenia in Older People -EWGSOP). Sarcopenia is considered if there is a decrease in gait velocity or muscle grip strength (measured with a dynamometer) and a decrease in muscle mass assessed by bioimpedance (BIA). Intermediate outcome measures (at 6, 12 and 24 months): a) weight loss, b) changes in body composition and distribution of body fat, c) glycemic control (HbA1) and insulin resistance (by HOMA index (HOmeostasis Model Assessment)), d) cardiovascular risk according to the REGICOR algorithm, e) functional capacity (according to Barthel Index and 2 Minute Walking Test), f) inflammatory markers (IL-6, CRP(C reactive protein), TNF(Tumor Necrosis Factor)-alpha and leptin) and g) anabolic hormones (IGF-1, ghrelin and testosterone).
The goal of this cross-sectional study is to evaluate the difference in cytokine profiling approach and mitochondrial function between geriatric sarcopenic patients (group 1) and geriatric non-sarcopenic patients (group 2) and healthy (group 3) geriatric participants.
