Start date: January 1, 2016
Phase:
Study type: Observational

The purpose of this study is to assess patient's function after functional limb restoring surgery, performed after ablative tumour surgery or trauma. However, there are no studies as yet providing objective proof of the recovery of function after this type of surgery. This study will use 3D Gait Analysis, Environmental simulation and Patient Reported Outcome Measures to compare patients with function restoring surgery against patients without function restoring surgery.

NCT ID: NCT04849689 Completed - Body Weight Clinical Trials

WFPB Lifestyle and Muscle Mass Preservation

WFPBmuscle
Start date: April 12, 2021
Phase:
Study type: Observational

Body fat (BF) and muscle mass showed opposing association with mortality. Whole-food, plant-based (WFPB) lifestyle programs has been on the rise lately especially due to impressive health benefits. The results of research on the effectiveness of popular weight loss diets in obese subjects showed 20 to 30% loss of lean muscle mass within to the total body weight loss, whereas in the whole-food, plant-based (vegan) diet the loss was up to 42%. Therefore, an open research problem is to find a way how to improve body composition in an effective and healthy way (i.e., losing of excess BF while maintaining muscle mass as much as possible) but still using stric plant-based (vegan) diet. Investigators will perform retrospective analysis of measurements of body composition and phase angle values of aprox. 200 participants who were on a WFPB lifestyle program from 2016 to 2021 and performed two successive measurements (initial and follow up (FU)), without body mass index (BMI) limitation on same medically approved and calibrated bioelectrical impedance (Tanita 780 S MA, Tokyo, Japan) and were not yet included in our previous studies. A WFPB lifestyle program were consisted of nutrition (i), (ii) physical activity and (iii) support system. Primary outcome include the following measures: BF % and FFM and to examine the change from initial values to FU values (by gender), according BMI classification (e.g,, normal, pre-obese and obese) with subanalysis for those participants who lost up to 5 kg/more and those who lost 5 kg or more of body weight.

NCT ID: NCT04777305 Recruiting - Obesity Clinical Trials

The POWER BARIATRIC Trial: Physical Outcomes With Exercise Regimens on BARIATRIC Patients

POWER
Start date: August 1, 2021
Phase: N/A
Study type: Interventional

This study aims to determine how different types of exercise regimens (resistance, aerobic, or combined exercise regimens) can be used to minimize muscle loss and mobilize body fat in severely obese patients after bariatric surgery (BS), despite the rapid surgery-induced weight loss. Additionally, the study will examine how changes in the intestinal microbiota following BS act as a mediation factor that alter tissue-specific responses in muscle and adipose tissue. The study will also evaluate the effect of different types of exercise regimens on cardiometabolic markers, endocrine response, and physical function following BS. Sixty sedentary (regular exercise <1 hour per week) candidates to bariatric surgery at Herzliya Medical Center will be recruited to participate in this six-month-long randomized control study. Participants will be randomly assigned to either one of three exercise regimens intervention groups (aerobic, resistance, or a combined exercise regimen combining aerobic and resistance exercises) or a control group that will receive standard care. Training will be supervised and matched for metabolic equivalent (METs). The intervention will take place at the Sylvan Adams Sports Institute at Tel Aviv University and an online platform. All measurements will be taken at a presurgical baseline assessment and throughout the study, and will include changes of muscle mass and adipose tissue distribution, measured by a 3-Tesla magnetic resonance imaging (MRI); body composition- will be assessed using multichannel bioelectrical impedance (Seca); Bone mass, will be measured by a Dual-energy X-ray absorptiometry (DEXA); microbiota composition and changes will be evaluated by stool samples that will be subjected to 16S ribosomal ribonucleic acid (16s rRNA) profiling and metagenomics analysis; fasting blood samples will be used to examine endocrine control and cardiometabolic markers; anthropometric measurements to assess surgery results associations with physical activity outcomes and physical function will be assessed by several validated performance assessments, including handgrip, six-minute walk, sit-to-stand, maximum voluntary contraction, and maximal oxygen consumption (VO2max).

NCT ID: NCT04756674 Withdrawn - Covid19 Clinical Trials

The Impact of Covid-19 on Skeletal Muscle

Start date: March 10, 2021
Phase:
Study type: Observational

With the recent worldwide outbreak of the COVID-19 infection and the huge impact it has had upon lives in the UK, it is key to increase knowledge on the impact of the virus on the body. Certain aspects of the virus' characteristics are also poorly understood: The reason behind the variation in response between individuals, and the long-term impacts of infection upon the body. It is already known from previous research that muscle-health plays an important role in health, with other illnesses known to have an impact upon muscle health. A large number of studies have investigated the relationship between muscle and health, with an increasing focus upon the impact upon the mitochondria within the muscle cells. Mitochondria are the energy-producing component of a cell and are vital not just for the muscle-cells but for the body as a whole. The researchers hope that by investigating the impact of COVID-19 infection upon human skeletal muscle, the question of why individuals have different responses to the infection and the mechanism of the longer-term impact of infection can be answered. This added knowledge will then, hopefully, be able to guide therapy targets in the future.

NCT ID: NCT04698798 Completed - Critical Illness Clinical Trials

Skeletal Muscle Wasting in SARS-CoV-2

SMW
Start date: January 2, 2021
Phase: N/A
Study type: Interventional

The SARS-CoV-2 pandemic causes a major burden on patient and staff admitted/working on the intensive care unit (ICU). Short, and especially long admission on the ICU causes major reductions in skeletal muscle mass (3-4% a day) and strength. Since it is now possible to reduce mortality on the ICU, short and long-term morbidity should be considered another principal endpoint after SARS-CoV-2 infection. Cachexia is defined as 'a complex metabolic syndrome associated with underlying illness and characterized by loss of muscle mass'. Its clinical features are weight loss, low albumin, anorexia, increased muscle protein breakdown and inflammation. There is strong evidence that cachexia develops rapidly in patients hospitalized for SARS-CoV-2 infection, especially on the ICU. Several mechanisms are believed to induce cachexia in SARS-CoV-2. Firstly, the virus can interact with muscle cells, by binding to the angiotensin converting enzyme 2 (ACE-2). In vitro studies have shown the virus can cause myofibrillar fragmentation into individual sarcomeres, in addition to loss of nuclear DNA in cardiomyocytes. Similar results were found during autopsies. On a cellular level, nothing is known about the effects of SARS-CoV-2 infection on skeletal muscle cells. However, up to 19.4% of patients present with myalgia and elevated levels of creatine kinases (>200U/l), suggesting skeletal muscle injury. Moreover, patients with SARS-CoV-2 infection are shown to have elevated levels of C-reactive protein and other inflammatory cytokines which can all affect skeletal muscles. The above mentioned factors are not the only mediators by which skeletal muscle mass might be affected in SARS-CoV-2. There are other known factors to affect skeletal muscle mass on the ICU, i.e. immobilization and mechanical ventilation, dietary intake (anorexia) and inflammatory cytokines. SARS-CoV-2 infection in combination with bed rest and mechanical ventilation can lead to severe muscle wasting and functional decline resulting in long-term morbidity. Until know there are no studies investigating acute skeletal muscle wasting in patients infected with SARS-CoV-2 and admitted to the ICU. As a result, there is a need of more in-depth understanding the effects of SARS-CoV-2 infection on muscle wasting. An optimal characterization of these effects may lead to improvement in morbidity and even mortality in the short and long term by the establishment of evidence-based rehabilitation programs for these patients.
