A hallmark of aging is an impaired ability to adequately recover following a stressor, such as muscle disuse, resulting in muscle fibrosis and weakness thereby increasing the risk for falls and loss of independence. Mechanistic-based therapeutic strategies to enhance muscle recovery in older adults do not exist. Metformin has been implicated to have positive effects on muscle size and function through non-glycemic mechanisms. Metformin has been shown to enhance macrophage function and lessen cellular senescence burden by targeting SASP in a variety of muscle interstitial cells. However, the role of metformin to improve muscle recovery in older adults following disuse atrophy through immunomodulating and senomorphic mechanisms have not been examined. Therefore, the purpose of this study is to conduct a randomized, double blind, placebo-controlled clinical trial in older adult participants to determine if short-term metformin delivery (vs placebo) during the recovery phase following disuse atrophy can improve muscle regrowth.
Spinal Muscular Atrophy (SMA) is a severe neuromuscular disorder characterized by the degeneration of alpha motor neurons in the spinal cord, resulting in progressive muscle atrophy and weakness, particularly in proximal and axial muscles. SMA causes respiratory muscle weakness, recurrent infections, and nocturnal hypoventilation, contributing significantly to morbidity and mortality. Children with SMA often display respiratory and trunk muscle weakness compared to healthy controls. Our project aims to investigate the impact of pulmonary rehabilitation, including inspiratory muscle training, along with trunk control exercises in children with SMA. The study will include 30 SMA patients aged 5-18, with maximum inspiratory capacity below 60 centimeters of water (cmH2O), predicted vital capacity over 25%, and the ability to sit unsupported for more than 5 seconds. The participants will be randomly assigned to two groups: Pulmonary Rehabilitation Group (Group 1, n=15) and Trunk Control Training Group (Group 2, n=15). Group 1 will undergo breathing exercises and inspiratory muscle training (IMT), involving diaphragmatic, pursed-lip, and segmental breathing. IMT will be administered with a portable device, starting at appropriate resistance and consisting of 10 cycles, 10 minutes each, once a day, with designated rest intervals. Also applied by calculating 30% of the maximal inspiratory pressure (MIP). During weekly clinic visits, the MIP value will be recalculated and the current threshold pressure value will be determined. In Group 2, alongside pulmonary rehabilitation, children will engage in trunk control exercises, progressively increasing in difficulty, focusing on pelvic control, proximal stabilization, and strengthening trunk and gluteal muscles. All interventions will be performed in front of a mirror. At the end of the 8-week intervention, MIP and Maximal Expiratory Pressure (MEP) will be used to measure respiratory muscle performance, spirometry will be used to monitor lung volume changes, and Peak Cough Flow will be used to evaluate the effectiveness of cough. The Trunk Control Measurement Scale, the Revised Upper Extremity Module, and the Children's Quality of Life Scale will assess trunk control, upper extremity functions, and quality of life, respectively. The Hammersmith Functional Motor Scale will assess gross motor functions and the Zarit Caregiver Burden Scale will inquire about familial factors affecting the child.
This global, retrospective, non-interventional, medical chart review (MCR), descriptive study collected patient-level data in regions outside the US. The study required a repeated data collection at follow-up dates from start of treatment with nusinersen, onasemnogene abeparvovec-xioi (OA), and/or risdiplam. At the start of data collection, the study team reached out to the health care providers (HCPs) involved in treating pediatric SMA patients for participating in this study. The physicians across the participating countries conducted a retrospective MCR of pediatric patients diagnosed with SMA who were treated with at least 1of the 3 novel disease-modifying treatments (DMTs): nusinersen, OA, and/or risdiplam. All health care encounters data i.e., emergency and inpatient admissions, surgery, and outpatient consultations of recruited patients, including their treatment with nusinersen, OA, and/or risdiplam, were abstracted to understand the treatment patterns as per routine clinical practice for SMA management globally. The first date of initial administration of 1 of the 3 target drugs was used as the "index date." Based on this, the record abstraction was performed through a retrospective MCR during the pre-index period, at index date and in the post-index period.
There is no cure to arrest or delay SBMA progression. It is estimated that ~1000 individuals are affected by SBMA in Italy at any given time (prevalence: 1.5/100000) with an annual incidence of 0.19/100000 males. Here, we are going to test the potential of beta2-agonist stimulation on muscle as a therapeutic avenue for SBMA. We have provided pre-clinical evidence that β-agonist stimulation may be a therapeutic strategy for SBMA. Moreover, we have shown that beta2-agonists are effective in improving motor function without relevant adverse events in a small cohort of SBMA patients. To establish safety and efficacy of clenbuterol as a cure for SBMA, we are conducting a multicenter, phase II, randomized, double-blind, parallel-group, single dose, placebo-controlled trial. Indeed, based on our preliminary data, some concerns remain to be addressed.
The goal of this clinical trial is to analyze the usability and safety of the robotic gait device EXPLORER in children with cerebral palsy, acquired brain injury and spinal muscular atrophy. Participants will use the exoskeletons in their home and the community and variables regarding safety and usability will be measured and recorded.
The goal of this clinical trial study is to test effects of leucine-enriched branched-chain amino acid (BCAA) in critically ill patients. The main questions it aims to answer are: • How are the changes in muscle thickness between groups at baseline and end of study • Is there a decrease in interleukin-6 levels between groups at baseline and end of study • Is there a decrease in sequential organ failure assessment score between groups at baseline and end of study. Participants will be given leucine-enriched branched-chain amino acid 40 g/day enterally or parenterally for 10 days. Researchers will compare with control groups to see if there is any changes between groups at baseline and end of study.
Spinal muscular atrophy (SMA) is a genetic neurodegenerative disease impacting spinal cord motor neurons, leading to motor and respiratory issues and, ultimately, death. With emerging therapies, a need arises to enhance motor function assessment in severely hypotonic infants (SMA type 1) as traditional scales on examination tables lack completeness due to gravity's influence. The study team has developed a "bath test" to observe infants' motor skills in water, eliminating gravity's effects. This test aims to detect subtle movements using inertial sensors, potentially revealing more active motor neurons in aquatic conditions. It aids in identifying infants with motor improvement potential, even if they show limited mobility outside water, and tracks disease progression and therapy responses. Presently, pediatric neurologists in France use parent-provided bathing videos for evaluations, but these lack standardization and precision. The study aims to establish a standardized evaluation protocol with quantifiable data. The study's key objective is to evaluate severely hypotonic SMA infants using inertial sensors, including accelerometers, gyrometers, and magnetometers. The study will conduct "dry" and "water" assessments using a specially designed bathtub. This method's goal is to quantify water-based movements accurately. Simultaneously, the study seeks to establish semi-quantitative evaluation criteria to create a clinical assessment scale for infant motor function in bathtubs. This scale will aid doctors in therapeutic decisions. The study will not influence the treatment or therapeutic decisions made for the children being tested. Collected data from "dry" and "water" conditions will be statistically analyzed and compared to reference motor assessment scales (e.g., CHOP INTEND and HINE) and electromyography (CMAP-EMG) results, commonly used in diagnosis and monitoring. Blurred video recordings will assist in protocol monitoring and sensor data analysis.
Cell-free fetal DNA (cffDNA) is present in the maternal blood from the early first trimester of gestation and makes up 5%-20% of the total circulating cell-free DNA (cfDNA) in maternal plasma. Its presence in maternal plasma has allowed development of noninvasive prenatal diagnosis for single-gene disorders (SGD-NIPD). This can be performed from 9 weeks of amenorrhea and offers an early, safe and accurate definitive diagnosis without the miscarriage risk associated with invasive procedures. One of the major difficulties is distinguishing fetal genotype in the high background of maternal cfDNA, which leads to several technical and analytical challenges. Besides, unlike noninvasive prenatal testing for aneuploidy, NIPD for monogenic diseases represent a smaller market opportunity, and many cases must be provided on a bespoke, patient- or disease-specific basis. As a result, implementation of SGD-NIPD remained sparse, with most testing being delivered in a research setting. The present project aims to take advantage of the unique French collaborative network to make SGD-NIPD possible for theoretically any monogenic disorder and any family.
This study aims to measure the spinal cord gray matter in patients with spinal muscular atrophy (SMA) type II and III in comparison with age- and sex-matched healthy controls (HC) using rAMIRA (radially sampled averaged magnetization inversion recovery acquisitions) imaging, a novel MRI (Magnetic Resonance Imaging) method. Patient and HC undergo MRI examinations, clinical/neurological (handheld dynamometry) and electrophysiological investigations (MUNIX, Motor Unit Number Index). Serum markers of neuro-axonal and astrocytic injury are also assessed.
