Filter by:Hereditary Inclusion Body Myopathy (HIBM) is a severe progressive metabolic myopathy caused by a defect in the biosynthetic pathway for sialic acid (SA), a critical component of many muscle proteins, resulting in a deficiency in SA in the muscles of HIBM patients. The effective replacement of the missing SA substrate is theoretically simple, and, in animal models, replacement with SA showed significant restoration of sialylation biochemistry and excellent reduction in muscle disease. These data show that replacement can achieve significant clinical benefit in muscle pathology, function, and survival.
Intensive care unit (ICU) hospitalization saves lives but often does so at a high personal cost to ICU survivors who frequently experience significant cognitive impairment and an array of physical and functional disabilities that limit their recovery and quality of life. While the problems experienced by these patients are likely amenable to rehabilitation, few ICU survivors receive focused rehabilitation. Recently, early physical rehabilitation in ICU patients has shown to improve the chances a patient will regain their pre-hospital functional status. Early cognitive rehabilitation for these patients has not yet been explored. This pilot study will determine the feasibility of early cognitive rehabilitation in ICU patients. The investigators will perform cognitive and physical rehabilitation, beginning in the earliest phases of critical illness, to determine the effect of these therapies on cognitive and functional outcomes in ICU survivors. The investigators hypothesize that combined cognitive and physical rehabilitation, started in the ICU, will improve recovery of cognitive and physical function as well as improve quality of life of ICU survivors.
This study consists of a series of prospective, randomized placebo-controlled n of 1 trials to objectively evaluate the reproducibility of subjective and objective symptoms among patients with a history of statin-related myopathy.
The aim of this study is to investigate pharmacokinetics and safety of N-acetylneuraminic acid in patients with Distal myopathy with rimmed vacuoles (DMRV) - hereditary inclusion body myopathy (hIBM). Dosages are 800mg single and three times a day and 800mg 3 times a day for 5 consecutive days. N-acetylneuraminic acid and N-glycolylneuraminic acid in serum and urine are measured before and after oral administration of N-acetylneuraminic acid.
The investigators propose to evaluate the effect of bezafibrate on metabolism during exercise in 22 adult patients affected with carnitine palmitoyltransferase II (CPTII) or very-long chain acyl-CoA-dehydrogenase (VLCAD) deficiencies. This study will be an 9-month, randomized, double-blind, placebo-controlled crossover trial. The trial will be conducted in two centers: Institut de Myologie, Pitié-Salpêtrière Hospital in France, and Rigshospitalet, University of Copenhagen, in Denmark. The main criteria for assessing the potential effect of this drug will be the fat oxidation rate studied during a moderate workload on cycle ergometer, after infusion of stable isotopes (palmitate and glucose tracers).
This study will be co-ordinated by Dr Hector Chinoy, Dr Robert G Cooper (Salford Royal NHS Foundation Trust / The University of Manchester) and Dr Ian N Bruce (Central Manchester University Hospitals NHS Foundation Trust/ The University of Manchester). An initial pilot study will be completed, to establish proof of concept of the study and to examine whether trends may observed of differences between cases and controls. Twenty five prevalent UK Caucasian adult IIM cases, confirmed by internationally accepted criteria, will be recruited via the Adult Onset Myositis clinic, Salford Royal NHS Foundation Trust. Age, gender and race-matched controls will be recruited on a 'best friend' system. At the Wellcome Trust Clinical Research Facility (WTCRF), The University of Manchester, facilities are already available for B-mode ultrasound CIMT measurement, Endo-PAT, lean body mass measurement and contrast echocardiography. Cases and controls will have their cardiovascular risk factors assessed using a standardised questionnaire and blood tests. Further tests performed will include blood pressure, electrocardiogram, lean body mass, B-mode ultrasound CIMT measurement and Endo-PAT. IIM cases will have additional blood tests and a clinical assessment to assess their disease status, and contrast echocardiography. As part of a linked study, subjects (but not controls) will also have Gd-DTPA-MRI of the heart performed.
With the great economic costs and traditionally poor outcomes among chronic temporomandibular joint and muscle disorder (TMJMD) patients, it has become important to treat patients in the acute state, in order to prevent these more chronic disability problems. This has been the goal of two past funded grant projects. Results of the initial project isolated risk factors that successfully predicted the development of chronicity with a 91% accuracy rate. A statistical algorithm was developed which was used in the second project to screen out "high-risk" patients. These patients were then randomly assigned an early intervention or non-intervention group. One-year follow-up evaluations documented the treatment efficacy and cost effectiveness of early intervention. These results have major implications for effective early intervention and significant health care cost savings for this prevalent pain and disability problem. For the present proposed project, we plan to implement this treatment program in order to evaluate its effectiveness in more community-based dental practices. This is in response to NIH's request for the implementation of evidence-based treatment approaches, developed in controlled clinical settings, to the "real world" of diverse practices in the community. Acute TMJMD patients will be recruited from two community-based clinics. Based upon our "risk" screening algorithm, high-risk patients will be randomly assigned to one of two groups (n=225/group): an early biobehavioral intervention or an attention-control group. It is hypothesized that the attention control "high-risk" patients will display more chronic TMJMD problems, relative to the "high-risk" early intervention patients, at one- and two-year follow-ups. A number of biopsychosocial measures will be evaluated, including chewing performance, the RDC/TMD, self-reported pain and stress, etc. Such a multi-level, multi-systems approach has not been applied to better understand the biopsychosocial underpinnings of TMJMD. Results from this component of the project will greatly aid in stimulating future research leading to the better understanding of TMJMD, as well as better tailoring of prescribed treatment regimens.
The primary aim of the project is to apply the non-invasive stimulated muscle force assessment system to i) intensive care unit patients and ii) patients with primary myopathy or subclinic myopathy (e.g., Duchenne muscular dystrophy, Myotonia, MH). The investigators will use this new methodology of force assessment to phenotype patients weakness during their illnesses (depict typical force pattern) and monitor recovery periods, or disease progression, respectively. This new system will be evaluated until the year 2018. The investigators will determine variables of isometric skeletal muscle force. These systems should serve as force monitoring tools and help to guide therapies.
Statins are a group of medications that are used to lower cholesterol levels. Although serious side effects are rare, some people taking statins experience muscle pain or weakness. This study will evaluate the number of people who experience mild muscle complaints and will determine the effect of statins on skeletal muscle strength, endurance, and aerobic exercise performance.
RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that did not respond to treatment may help doctors learn more about the disease and plan the best treatment. PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia that did not respond to treatment.
