Identifying Therapeutic Targets of Accelerated Sarcopenia

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 ? of older Americans have type 2 diabetes, and about ? 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 Impact of a Resistance Training Intervention on Blood Pressure Control in Older Adults With Sarcopenia

Current prevention and treatment of high blood pressure (BP) in sarcopenia, by non-pharmacological approaches remain limited and are far from optimal. This randomized control intervention pilot study will provide new evidence of the unexplored relationship between muscle strength and high BP in sarcopenia, and experimentally test the effects of an evidence-based progressive resistance training intervention on BP, while also examining reversibility to identify muscle strength as a non-pharmacological target for BP control in older sarcopenic adults.

Ultrasound (US) Measurement of Sarcopenia in the Elder Subject

Sarcopenia is a generalized, progressive and multifactorial muscle impairment, causing multiple pathologies and their consequences such as falls, fractures, dependence, worsening of cognitive disorders and death. Interventions to combat the progression of sarcopenia should be introduced as soon as clinically suspected, based on functional tests to measure muscle strength. Diagnostic confirmation of sarcopenia can be done using several validated methods of estimating muscle mass: magnetic resonance imaging (MRI), computed tomography (CT), biphotonic absorptiometry (DEXA) or bio-impedanceometry. Their availability in clinical routine remains limited due to their high costs and/or lack of accessibility depending on the place of practice. On the other hand, there are certain pitfalls for carrying out these various examinations, in connection with several common clinical problems in the study population: mobility disorders and neurodegenerative disorders disabling for transport and access to the examination table for imaging examinations, hydration disorders distorting measures for bio-impedancetry. Previous studies suggest that ultrasound may be as effective a tool as previous methods for diagnostic confirmation of sarcopenia. Because of its non-invasive and non-irradiating nature, its affordability, its short duration of realization, its availability and its low constraints of realization, the ultrasound could help to remove some of the current limits to the diagnostic confirmation of sarcopenia. The investigators hypothesis is that ultrasound can be used to implement a simple and reliable protocol for assessing sarcopenia in the elderly. It could also be used to detect sarcopenia at an early stage ("presarcopenia") while the decrease in muscle mass is not yet accompanied by a decrease in skeletal muscle strength.

The Whole Body Vibration for Sarcopenic Hospitalized Patients Aged 80+ Years

Resistance training have been recommended for sarcopenic patients. However, the whole body vibration training would further benefit for sarcopenic patients on the basis of resistance training remains unclear. The purpose of this study is to explore the effect of the whole body vibration training on improving the mobility of elderly patients with sarcopenia. The whole body vibration involves different frequencies that can improve muscle strength and keep aged upright, including the legs and core. These kinds of exercises can improve stability and help prevent falls.

Impacts of Nicotinamide Riboside on Functional Capacity and Muscle Physiology in Older Veterans

Frailty is an age-associated clinical condition of poor physiological reserve that increases risks for falls, hospitalization and mortality. Nicotinamide adenine dinucleotide (NAD) is a critical co-factor needed for many cellular processes. The natural levels of NAD decline aging and this has been linked to physical performance decline in animals. Human trials have demonstrated that nicotinamide riboside (NR), a form of vitamin B3, is safe and effectively increases NAD+ levels. In animal studies, NR improves treadmill performance and muscle quality. Here the investigators propose a double-blind randomized control trial to assess the benefits of NR supplementation on human muscle function and physiology. The investigators anticipate the research findings will support the use of this nutritional supplement to improve the health of Veterans during aging.

Muscular Rehabilitation by Eccentric Exercise After Severe COVID-19 Infection

With the COVID-19 pandemic, the number of patients to be treated in rehabilitation increased . Hospitalization for severe infection can induce muscular atrophy and muscular dysfunction that persists for several months and rehabilitation capacities may be exceeded. Exercises in eccentric mode could be performed, inducing greater muscular hypertrophy, muscle strength, power and speed than concentric exercises. The goal of this study was to compare functional recovery at 2 months after a training program in eccentric and concentric mode after severe COVID-19. An effective rehabilitation could help reduce costs and duration of care.

Diaphragm Kinetics Following Hepatic Resection

Sarcopenia is associated with reduced pulmonary function in healthy adults, as well as with increased risk of pneumonia following abdominal surgery. Consequentially, postoperative pneumonia prolongs hospital admission, and increases in-hospital mortality following a range of surgical interventions. Little is known about the function of the diaphragm in the context of sarcopenia and wasting disorders or how its function is influenced by abdominal surgery. Liver surgery induces reactive pleural effusion in most patients, compromising post-operative pulmonary function. Hypotheses: Both major hepatic resection and sarcopenia have a measurable impact on diaphragm function. Sarcopenia is associated with reduced preoperative diaphragm function, and that patients with reduced preoperative diaphragm function show a greater decline and reduced recovery of diaphragm function following major hepatic resection. Goals: The primary goal of this study is to evaluate whether sarcopenic patients have a reduced diaphragm function prior to major liver resection compared to non-sarcopenic patients, and to evaluate whether sarcopenic patients show a greater reduction in respiratory muscle function following major liver resection when compared to non-sarcopenic patients. Methods and analysis: Trans-costal B-mode, M-mode ultrasound and speckle tracking imaging will be used to assess diaphragm function perioperatively in patients undergoing major hepatic resection starting one day prior to surgery and up to thirty days after surgery. In addition, rectus abdominis and quadriceps femoris muscles thickness will be measured using ultrasound to measure sarcopenia, and pulmonary function will be measured using a hand-held bedside spirometer. Muscle mass will be determined preoperatively using CT-muscle volumetry of abdominal muscle and adipose tissue at the third lumbar vertebra level (L3). Muscle function will be assessed using handgrip strength and physical condition will be measured with a short physical performance battery (SPPB). A rectus abdominis muscle biopsy will be taken intraoperatively to measure proteolytic and mitochondrial activity as well as inflammation and redox status. Systemic inflammation and sarcopenia biomarkers will be assessed in serum acquired perioperatively.

Protein and Skeletal Muscle in Older Twins: Role of the Gut Microbiome

Research Question: Does the gut microbiome contribute to muscle anabolic resistance to protein supplementation in older adults? Background: Loss of muscle occurs with age and skeletal muscle in older adults can display anabolic resistance to protein in diet. It has been hypothesised that the gut microbiome may play a role in this relationship and therefore could be targeted. Aim: This trial aims to test whether modulation of the gut microbiome, in addition to protein supplementation, can improve skeletal muscle function versus protein supplementation alone. Methods: Double blinded, randomised, placebo controlled, dietary intervention study. Twin pairs will be randomised to either receive protein supplementation plus placebo or protein supplementation plus a gut microbiome modulator (prebiotic plus probiotic) for 12 weeks. Primary outcome will be muscle function measured using chair-rise time. Conclusion: Anabolic resistance warrants further characterisation to guide future therapeutic interventions, especially considering its role in the development of disability, sarcopenia and frailty.

A Study of Perioperative Oral Nutritional Support for Patients Having Surgery for Colon Cancer, Peri-Nutri

This is a multicenter, unblinded, randomized study. The aim of this study is to research whether preoperative and postoperative oral nutritional supplement (ONS) (Resource 2.5 Compact/fibre compact) used at least 2 weeks prior the surgery and 10 days after surgery can improve the nutritional status of a colon cancer patient and reduce number of complications. The aim is also to investigate whether the oral nutritional support can shorten the hospital stay and improve the patients´ quality of life. The aim is also to find out whether the oral nutritional support can reduce 90-day mortality and improve disease free and overall survival. Consecutive patients diagnosed with primary adenocarcinoma of the colon who are considered for radical surgical procedure are enrolled in this study provided that the inclusion criteria are filled. Patients in the intervention group start oral nutritional support (ONS)2 portions a day for about 2 weeks prior to the operation starting at the time of randomization and continue ONS 10 days after the operation. Control group will continue with their regular diet without ONS until the operation. Both groups keep a food diary for 4 days right after the randomization and both one month and three months after the operation to assess the energy and nutrient intakes. Laboratory markers, NRS 2002, quality of life questionnaire, exercise questionnaire, bioelectrical impedance analysis (BIA) and handgrip strength as well as body composition on computer tomography scan are assessed prior to any treatment or supplement in order to estimate the patients' well-being and nutritional status prior to surgical operation. Laboratory parameters and QoL questionnaire are repeated right before the operation on admission to hospital as well as about 30 and 90 days after the operation in addition to BIA, handgrip strength to assess the effect of nutritional support. Data on complications, infections, length of stay in the hospital and mortality are collected. Another arm in this research is to discover more information on biological markers in colon cancer and cancer related malnutrition thus providing targets for future treatment and prognostic predictors. Tissue samples are collected during this research at the surgery.
