Filter by:The primary aim of this research proposal is to examine whether this novel training program approach is capable to tackle excessive loss in muscle mass, function and contractile capacity with aging. Previous investigations have universally shown a dramatic loss in type II muscle fibers, while certain countermeasures in their follow-up studies were generally ineffective and limited to attenuate this phenomenon. Probably, they failed to meet recruitment threshold of larger motor units and subsequently innervate type II muscle fibers. Furthermore, previous investigations also failed to provide any data on specific blood markers that may provide additional insight into muscle fiber loss with aging. Muscle fibers type II play a crucial role in the human ability to produce as much as force as possible over a limited time-frame (e.g. 100-200 ms) to counteract unexpected perturbations during stair climbing for example and thus avoiding falls. Therefore, this data collection would be noteworthy in particular, especially for this population due to health-related outcomes and healthy aging process. Since age-related decline is accelerated already after short bouts of physical inactivity, with small recovery potential, any attempt to counteract age-related and disuse-related decline have high clinical significance. Based on the findings, data collected may aid in development of safety guidelines and protocols aimed at reducing health risks in this specific population. Importantly, in case the aforementioned hypotheses are confirmed, present findings may offer important information to the healthcare system, especially for reducing economic burden.
Our study is a randomized controlled study and the subjects included in the study will be divided into three groups as virtual reality training, biofeedback training, and conventional rehabilitation.
Visits to the emergency department (ED) for chest pain are extremely common and require a safe, rapid and efficacious treatment algorithm to exclude a possible AMI. These diagnostic algorithms are partly based on an important laboratory value, which showed growing utility in the diagnostic and prognostic of many cardiovascular diseases in the last years : cardiac troponin. However, some patients with muscle disease often present with unexplained elevated high-sensitive cardiac Troponin T (hs-cTnT) levels in the absence of cardiac disease. The investigators aim at the characterization of the behaviour of this biomarker and its alternative (high-sensitive cardiac Troponin I), which will have important clinical implications on patients management.
Acute skeletal muscle wasting in ICU patients is associated with functional impairment and with increased risk of death. Of what we know today, physical disability can persist up to 5 years. Adequate nutrition is the basis for an optimal recovery for ICU patients and for prevention of muscle wasting. Today, continuous feeding is still the standard enteral nutrition form for patients in the ICU to limit the incidence of aspiration. A study of Serpa et al. and Georgia et al. compared the continuous feeding versus a bolus nutrition with a feeding time of 30 - 60 minutes every 4 hours. They showed no statistical differences in complications between both groups. ProBoNo is a prospective, randomized, controlled pilot study of critically ill patients with a protein- rich formula to explore the impact of continuous or intermittent bolus nutrition on muscle breakdown in ICU patients. The investigators would like to recruit 68 patients during the first 24 hours after surgical intensive care unit admission. Prior beginning of nutrition administration, and on the 7th day thereafter the investigators will perform a muscle biopsy and an ultrasound from the vastus lateralis muscle in both groups. The primary outcome is the time from 6.00 am of the following day after admission until the patient reaches his daily protein's target quantity. Secondary outcomes include the diameter and densitiy of the hamstrings assessed by ultrasound and histology, the process of gastric residual volume, number of diarrhoea events and laboratory findings like glucose, urea and insulin like growth factor (IGF)-1, all compared between the two time points. Intermittent feeding is not only more natural and could help to limit the muscle wasting in ICU patients, it is also easier to handle for the ICU caring medical team. A trial from Georgia et al. in 2007 compared continuous to intermittent enteral nutrition. They found that the intermittently fed patients reached their nutrition goal faster than those being continuously nourished. This might in part be explained by feeding interruptions in the continuous feeding regimen. Presumably, preoperative holding of tube feedings in the continuous nutrition group most commonly caused interruptions. Thus, independently from prevention of muscle breakdown, a bolus nutrition would be more attractive.
The purpose of this survey is to evaluate the long-term safety and efficacy of leuprorelin acetate injection kit 11.25 mg in patients with spinal and bulbar muscular atrophy (SBMA) in the routine clinical setting.
The aim of the study is to investigate the effect of exercise in form of whole-body electromyostimulation (WB-EMS) on early tumor-induced muscular dysfunction. It is anticipated to gain detailed knowledge about composition and metabolism of skeletal muscle cells, and single muscle fiber functionality. To determine key factors leading to impaired force generation and thus decreased muscle strength in cancer patients who are suspected to develop or already show early signs of tumor cachexia is crucial for the establishment of effective cancer treatment. Comparative analysis of skeletal muscle biopsies taken from the abdomen of patients during indicated surgeries will be conducted. The patients will be allocated to the following study groups: a) Study group 1: Patients without cancer, b) Study group 2: Patients with solid tumors who did not perform physical training and c) Study group 3: Patients with solid tumors who executed physical training in form of WB-EMS. The investigation can help to understand skeletal muscle physiology under exercise and to get a better insight into the effects of physical training on early-stage muscle atrophy, both on cellular and molecular level. Initially, it is planned to identify the inflammation and nutrition status of the patients, and to determine skeletal muscle strength. It is anticipated to explore muscle protein composition, particularly myosin to actin ratio and their interaction. Biochemical analysis and the examination of the cellular ultra-structure should enhance the knowledge about the key mechanisms controlling the contractile apparatus of single muscle fibers in order to determine the quality of muscle force. Taken together, these investigations will help to better understand muscle atrophy in advanced cancer patients, and might support the development of targeted anti-cachectic therapies, that can be applied already in early phases of the tumor disease to significantly improve the patients' prognosis and their quality of life.

The purpose of the Clinical Procedures To Support Research (CAPTURE) study is to utilize information collected in the medical record to learn more about a disease called amyotrophic lateral sclerosis (ALS) and related disorders.
Patients requiring prolonged time on the ventilator are susceptible to a wide range of clinical complications and excess mortality. It is therefore imperative for them to wean at the earliest possible time. Respiratory muscle weakness due to disuse of these muscles is a major underlying factor for weaning failure. Surprisingly, there is not much known about the impact of critical illness and MV on the expiratory abdominal wall muscles.These muscles are immediately activated as ventilation demands increase and are important in supporting respiratory function in patients with diaphragm weakness. Weakness of expiratory abdominal wall muscles will result in a decreased cough function and reduced ventilatory capacity. These are considerable causes of weaning failure and (re)hospitalisation for respiratory complications such as pneumonia. Recent evidence shows that neuromuscular electrical stimulation (NMES) can be used as a safe therapy to maintain skeletal muscle function in critically ill patients. This study will be the first to test the hypothesis that breath-synchronized NMES of the abdominal wall muscles can prevent expiratory muscle atrophy during the acute stages of MV.
The primary objective of this study is to investigate the natural history of spinal muscular atrophy (SMA) types 2 and 3 patients in Taiwan. This study will provide further insights into the clinical course SMA. Several analyses will be conducted regarding overall survival, demographic characteristics, motor function, respiratory and nutritional support, and genotype and phenotype correlation.
