Active clinical trials for "Muscular Diseases"

The purpose of this research study is to test the feasibility and response of a new exercise protocol on improving physical activity in adolescents with cerebral palsy.

The Myotonic Dystrophy Family Registry (MDFR) is an online, patient-entered database that collects information on myotonic dystrophy (DM) to aid researchers in developing new, effective treatments and help identify participants for research studies and clinical trials.

Due to the widespread use of NGS, TTN is emerging as a major causative gene in neuromuscular disorders, with high clinical heterogeneity. The mechanisms underlying the phenotypic variability and mode of inheritance (recessive or dominant) of titinopathies are poorly understood. They involve the primordial structural functions of titin on the formation and stability of the sarcomere, as well as its interactions with other proteins. We identified by NGS, in patients with skeletal myopathy (with or without cardiomyopathy), several potentially disease causing TTN variants. The specific aims of the present project are to implement functional studies (transcripts, protein analyses, in vitro protein-protein interaction studies) to evaluate the effect of TTN variants on the transcripts and protein in order to perform phenotype-genotype correlation studies. We participate to the national "titin network" and to international efforts for the understanding of the molecular bases of titinopathies. Genomic characterisation opens the way to develop cellular models of titinopathy, derived from patient biopsies. This is also a mandatory first step for the design of novel therapeutic approaches.

The purpose of this study is to determine whether patients with acute kidney injury requiring renal replacement therapy have a higher incidence of muscle wasting than controls and whether the course of recovery is longer compared to controls.

ICU-acquired weakness represents a common and often devastating disease process which affects greater than 50% of critically ill patients. This pathogenesis of this acquired disease is multifactorial and results in variable severity, ranging from mild, transient to severe, permanent dysfunction of peripheral nerves in additional to muscle. In affected patients, weakness may persist for months to years after the acute phase of their illness, and has been implicated as a major contributor to decreased functional status and quality of life. Muscle ultrasound has been validated for assessment of muscle size as well as diagnosis of myopathic and neuropathic changes in patients with other known neuromuscular diseases. The use of muscle ultrasound or other imaging modalities for diagnosis or monitoring of ICU-acquired weakness has not been studied, although a single study using muscle ultrasound has shown significant change in muscle size in ICU patients receiving high dose corticosteroids and a prolonged course of paralytic agents. The investigators plan to use multiple modalities to examine skeletal muscle catabolism, function, and structure in patients during critical illness and recovery. The investigators will combine physical exam, hand grip dynamometry, electrophysiologic studies, serum biomarkers, muscle biopsies, and muscle ultrasound to assess a group of critically ill patients during their hospital stay. The investigators will obtain additional data, including neuropsychiatric assessments, severity of illness scores, administration of potentially harmful medications, and pertinent daily laboratory data. This study will last approximately 12 months.

This study is an observational longitudinal study involving the use of MRIs and video recordings taken at home of patients completing basic tasks. Once consent is obtained, subjects will be asked to schedule an appointment with radiology to undergo the listed MRIs of the heart and/or muscle. Subjects will also be given instructions on how to use the video recording app on their personal devices, or study provided device. The subjects will be followed regularly over the course of two years, submitting video recordings of their movements and reporting to Mayo Clinic for MRIs as scheduled.

Atrial myopathy is considered to be the underlying cause of a large proportion of embolic strokes of undetermined source. However, the definition of this atrial condition is not well delineated while its identification could lead to prescription on anticoagulation in order to avoid stroke recurences. This study aims to identify new markers of atrial myopathy and choosed a multi parametric approach with electrical, echographical, biological and 4D flow CMR derived markers.

As a T2T, our patients with idiopathic inflammatory myopathies will receive pulse therapies with methyprednisolone and/or human intravenous immunoglobulin, or only methyprednisolone at disease onset. This scheme is an internal routine protocol of our Service.

This study aims to understand the state of onset of NLSD(neutral lipid storage disease) / TGCV(triglyceride deposit cardiovasculopathy) worldwide, background information of affected patients, and natural history of the disease, as well as exploring the prognostic factors and assessing the efficacy of disease-specific treatment.

In the Congenital Myopathy Research Program at Boston Children's Hospital and Harvard Medical School, the researchers are studying the congenital myopathies (neuromuscular diseases present from birth), including central core disease, centronuclear/myotubular myopathy, congenital fiber type disproportion, multiminicore disease, nemaline myopathy, rigid spine muscular dystrophy, SELENON (SEPN1), RYR1 myopathy, ADSS1 (ADSSL) Myopathy and undefined congenital myopathies. The primary goal of the research is to better understand the genes and proteins (gene products) involved in muscle functioning and disease. The researchers hope that our studies will allow for improved diagnosis and treatment of individuals with congenital myopathies in the future.
