Medical Decision Making in Multiple System Atrophy
Multiple System AtrophyThe goal of this clinical study is to evaluate the effects of a personalized symptomatic treatment plan integrated with monthly telemedicine and mobile palliative care interventions on a population of individuals diagnosed with Multiple System Atrophy (MSA) and their informal caregivers. The aim is to improve the quality of life of MSA patients and their caregivers, as well as provide them with better support during the disease progression. After a baseline visit, all 46 patients will receive a personalized therapeutic plan (including medical treatment, physiotherapy, logotherapy and occupational therapy excercises and psychological support) and contact with social workers and a palliative care team. They willl then be re-evaluated at 6-,12-, 18- month visits. Semi-structured online interviews at baseline and 12 month visit will collect patients' individual healthcare preferences, which will be taken into account in the preparation of the individual therapeutic plan. Twenty-three patients will be randomized to receive monthly telemedicine visits. Assessment of patients´satisfaction with the therapeutic plan, with the palliative interventions (when they occurred) and the telemedicine visits will be carried over the 18 month period. Forty-six informal caregivers will be invited to participate with semi-structured online interviews and assessment of their QoL and caregivers' burden.
Study of the Functional Effects of Nusinersen in 5q-spinal Muscular Amyotrophy Adults (SMA Type...
Spinal Muscular AtrophySpinal Muscular Atrophy (SMA) is an autosomal recessive disease caused by a mutation of exon 7, in 95% of cases, encoding the gene for the motor neuron survival protein called SMN1 (Survival Motor Neuron) located on chromosome 5q. Patients with an SMA-5q mutation suffer from progressive muscle deficiency and subsequent atrophy induced by degeneration of motor neurons in the spinal cord. Gene therapy is now available for the management of spinal muscular atrophy and nusinersen is the first approved treatment. Nusinersen has been granted marketing authorization in France since May 30, 2017. Nusinersen has a high level of medical service rendered (MSR) for types I, II, and III, but the improvement in medical service rendered (IMSR) is assessed as moderate for types I and II. For Type III, IMSR is not known.
Sex-specific Determinants of Early-phase Recovery From Skeletal Muscle Disuse
Atrophy of Muscle Due to DisuseRehabilitationThis project is a 2-phase, randomized clinical trial that includes 7 days of unilateral leg disuse (Phase 1), immediately followed by 14 days of bilateral leg rehabilitation (Phase 2). The investigators will recruit cohorts of healthy middle-aged men and women to address their aims: Demonstrate the sex-specific effects of skeletal muscle disuse (Phase 1) Identify key molecular determinates of susceptibility of skeletal muscle atrophy (Phase 1) Map the early, sex-specific molecular time-course of rehabilitation (Phase 2) Determine if disused and healthy muscle respond similarly to exercise (Phase 2) Healthy, middle-age men and post-menopausal women (50-65 years) will be recruited from the greater Houston/Galveston area. This under-represented research demographic demonstrate few negative metabolic or phenotypic signs of advanced age, but are at increased risk of being hospitalized and experiencing accelerated loss of lean mass and muscle function that parallels a much older population. The goal of this study is to characterize phenotypic and molecular skeletal muscle changes in middle-aged men and women during critical periods of disuse and rehabilitation and ultimately direct the development of targeted and effective prevention and treatment strategies.
Outcome Measures and Biomarkers in a Cohort of Spinal Muscular Atrophy Type III/ IV Patients
Spinal Muscular AtrophyThe "SMOB" project intends to contribute to fill the gap with reliable and operational outcome measures for type III and IV SMA. In analysing the reliability in imaging (spinal and muscular), electrophysiology analysis (MUNIX), and evaluate the evolution of respiratory function for 50 patients' cohort. The investigators would also take the opportunity to collect biologic samples in order to investigate genetic markers and to assess quality of life of patients by QoL-gNMD questionnaire. The investigators aim to build a database that will allow us to evaluate the effectiveness of a new therapy for adult SMA patients by studying the natural history of the disease. The investigators have distributed the various expertise in Work Package where several centers are involved. This study is original in that it evaluates the parameters of qMRI and MUNIX in correlation with blood biomarkers. To our knowledge, there are no quantitative MRI (spinal and muscular) biomarkers and/or electrophysiological (MUNIX technique) highlighted for tracking the progression of the adult form of SMA type III and IV. This pilot study would allow identification of predictive markers of the disease progression, and to have validated, sensitive to change and relevant measurement tools that could be used as endpoints in future therapeutic trials.
Quantification of Motor Function in Infants With Spinal Muscular Atrophy Treated With Innovative...
Spinal Muscular AtrophyThe aim of the study is to propose a method for quantifying motor function in infants with spinal muscular atrophy treated with innovative therapies using inertial sensors.
Skeletal Muscle Atrophy and Dysfunction Following Total Knee Arthroplasty
Knee OsteoarthritisTotal knee replacement, or arthroplasty, is the final clinical intervention available to relieve pain and functional limitations related to advanced stage knee osteoarthritis. Despite its beneficial effects, the early post-surgical period is characterized by the erosion of lower extremity muscle size and strength that cause further disability and slow functional recovery. While the detrimental effects of this period on muscle are widely recognized, the mechanisms underlying these adaptations are poorly understood and there are currently no widely-accepted clinical interventions to counter them

InactivityPhysical10 moreThe purpose of this study is to assess the impact of 3-days reduced physical activity (<1500 steps/day) with/without 'exercise snacks' (15 chair stands with calf raises every 30 min) on skeletal muscle metabolic health.
Vulvovaginal Atrophy Correction Using Neodymium Laser
Postmenopausal PeriodVaginal Atrophy1 moreThe aim of this prospective study is characteristic of changes in the vaginal wall and vulva after treatment of neodymium laser radiation with a wavelength of 1064 nm. To assess the condition of the vaginal walls and vulva before and after laser treatment, the following methods will be used: vaginal health index, perineometry, elastography of vulva, cytological methods. Female Sexual Function Index (FSFI), The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), Vulvovaginal Symptoms Questionnaire (VSQ), Visual Analogue Scale (VAS) will be used to collect feedback on changes in the participants life quality. Total up to 120 participants with postmenopausal atrophy will be involved in the study. Participants will be divided into three groups: laser treatment group, topical hormones treatment group, and both laser treatment with topical hormones application group, by 40 participants in each. The time intervals between tests will be the same for all groups. Thus, a direct comparison between conventional treatment (topical hormones), laser treatment and combine laser and topical hormones therapy of the vaginal atrophy will be made. The main hypothesis of the study is improvement in condition of the vaginal walls after laser treatment and laser treatment with hormones application compared with the initial state of not less than thirty percent of participants, and improvement in condition on average compared with the hormones only therapy group.
Insulin Resistance in Multiple System Atrophy
Multiple System AtrophyMultiple system atrophy (MSA) is a rare and fatal neurodegenerative disorder. The pathologic hallmark is the accumulation of aggregated alpha-synuclein in oligodendrocytes forming glial cytoplasmic inclusions. Some symptomatic treatments are available while disease-modification remains an unmet treatment need. Post-mortem findings suggest insulin resistance, i.e. reduced insulin signaling, in the brains of MSA patients. The aim of this study is to complete the target validation of insulin resistance for future treatment trials.
