Filter by:The primary objective of this study is to evaluate the clinical outcomes following treatment with nusinersen in participants with spinal muscular atrophy (SMA) who previously received onasemnogene abeparvovec. The secondary objectives of this study are to evaluate the safety and tolerability; clinical outcomes and pharmacodynamics (PD) of nusinersen treatment in participants with SMA who previously received onasemnogene abeparvovec.
The loss of muscle mass post-surgery confounds recovery efforts and leads to a delay in patient's ability to return to activities. Although the use of testosterone in aging and chronic muscle loss has been investigated, this study could prove short-term use of testosterone efficacious in preventing muscle atrophy due to surgery. We hypothesize that by bracketing an indexed knee surgery with testosterone undecanoate injections, post-surgical quadriceps muscle loss may be minimized. Determination of the effect of intra-muscular (IM) testosterone injections in preventing quadriceps muscle loss are measured by serial MRI and manual measurements of quadriceps cross-section.
This study aims in investigating the effects of a core muscles' strengthening program on core muscles' atrophy and contraction ability. Twenty healthy adults recruited and randomly assigned to either a 5-week training group developed to activate and strengthen local trunk muscles or a control group. The training program includes isometric bridging exercises from various positions and dynamic exercises for lumbopelvic stability. Core muscles' thickness will be assessed at rest and contracting conditions, prior and after the intervention, using ultrasonography.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent airway obstruction and inflammatory response of the lungs and bronchi. Episodes of exacerbations contribute to increase the severity and prognosis of the disease. Muscle dysfunction (loss of strengh and muscle mass) is one of comorbidities affecting 30% to 60% of patients and playing a key role in their prognosis. During exacerbation, some studies have suggested an association between muscle dysfunction and modifications of inflammatory circulating factors such as CRP, TNF-alpha, IL- 6, IL8, but no exhaustive study has identified precisely one (or more) biomarker(s) that can induce this muscle wasting during the exacerbation of COPD. Our hypothesis is that the serum of exacerbated COPD patients represents a deleterious microenvironment for the muscle cells which would amplify the mechanisms of atrophy linked to hospitalization. Our team has already developed a cell culture model to study the effects of the plasma microenvironment on atrophy of cultured myotubes. The investigators have shown that the serum of COPD patients can induce muscle atrophy. The objectives of this study are : 1/ to evaluate the effects of circulating pro-inflammatory factors on atrophy and the myogenic capacities of muscle cells; and 2/ to identify one (or more) circulating biomarker (s) that may be responsible for the muscle damage induced by the microenvironment of hospitalized patients for exacerbation of COPD. First, myotubes and myoblasts of healthy subjects will be cultivated with 9 exacerbation copd patient serum or 9 copd patient serum or 9 healthy subject serum. Myotube diameters, atrophy, inflammatory and oxidative stress markers and alteration of the myogenic capacity of satellite cells will be compared between three groups. Second, the differential expression of circulating proinflammatory molecules will be compared in the serum of the three groups. Identifying circulating factors associated with muscle weakness is a necessary step to better understand the mechanisms and consider a personalized therapeutic approach that can improve the functional and clinical prognosis of disease. .
This study is to evaluate the correlation between muscle atrophy (MA), sagittal alignment, and stenosis degree in patients with lumbar spinal Stenosis (LSS). From existing radiological images, specific radiographic parameters will be extracted. General Information (Age, sex, levels of stenosis, duration of symptoms) will be extracted from patient files.
The purpose of this study is to evaluate post-operative outcomes after meniscus surgery in participants undergoing blood flow restriction training as a rehabilitative adjunct compared to those with standard rehabilitation.
While "conditioning" by exercise training has been widely evaluated, the available literature on "passive deconditioning" (i.e. forced deconditioning) is predominately limited to studies with or with almost complete mechanical and/or metabolic immobilization/sedation of the respective functional system (e.g. paralysis, bedriddenness). Vice versa, the effects of moderately long interruptions of dedicated types of exercise while maintaining everyday activity are rarely addressed. However, this topic is of high relevance, e.g. considering that breaks of health-related exercise programs due to increased family/occupational stress, vacation or temporary orthopedic limitation are rather frequent in everyday life. In the present project we aimed to determine the effects of 3 months of physical deconditioning due to COVID-19 induced lockdown after 13 month of high intensity endurance and resistance exercise in early postmenopausal women on parameters related to health and physical fitness.
The primary objective of this study is to evaluate the safety of nusinersen sodium injection in the postmarketing setting in China.The secondary objectives are to collect data on the efficacy and the pharmacokinetics of nusinersen sodium injection in the post-marketing setting in China.
This study aims to characterize the clinical-epidemiological profile and baseline characteristics of patients with spinal muscular atrophy (SMA) 5q types II and III in follow-up at the Brazilian Unified Public Health System (SUS). The study data will be based on patients´ medical records from several Brazilian public hospitals, which will be defined by the Brazilian Ministry of Health (MS).
Muscle weakness or atrophy is a common condition following acute and chronic musculoskeletal injuries. Strength training is an imperative component in clinical rehabilitation of musculoskeletal injuries. Heavy exercise loads (approximately 70% of one repetition maximum) is necessary to elicit muscle hypertrophy and strength gains. However, patients with severe muscle atrophy are frequently unable to tolerate these loads due to pain. Blood flow resistance training with low resistance loads may be used to safely develop muscle strength.
