Acceptability, validity and responsiveness of inertial measurement units for assessing motor recovery after gene therapy in infants with early onset spinal muscular atrophy: a prospective cohort study.

Background: Onasemnogene abeparvovec gene replacement therapy (GT) has changed the prognosis of patients with spinal muscular atrophy (SMA) with variable outcome regarding motor development in symptomatic patients. This pilot study evaluates acceptability, validity and clinical relevance of Inertial Measurement Units (IMU) to monitor spontaneous movement recovery in early onset SMA patients after GT.

Methods: Clinical assessments including CHOPINTEND score (the gold standard motor score for infants with SMA) and IMU measurements were performed before (M0) and repeatedly after GT.

Correlations between clinical motor scores and CMAP in patients with type 2 spinal muscular amyotrophy treated with nusinersen.

Background: Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by the degeneration of the anterior horn cells of the spinal cord. Nusinersen for the treatment of SMA has been covered by public healthcare in France since May 2017.

Objective: Our aim was to investigate whether there is a correlation between clinical and compound motor action potential (CMAP) measurements in SMA patients treated with nusinersen after 3  years' follow-up.

Motor outcomes in patients with infantile and juvenile Pompe disease: Lessons from neurophysiological findings.

In Infantile Onset Pompe Disease (IOPD), enzyme replacement therapy (ERT) may improve survival, cardiac function, and motor development. However, even with early enzyme replacement therapy, some patients experienced poor response to ERT and abnormal motor milestones that could be due to motor neuron involvement. In this long-term retrospective study, we analyzed concomitant clinical motor outcomes and electroneuromyography (ENMG) findings in patients with IOPD and Juvenile Onset Pompe Disease (JOPD).

A new score combining compound muscle action potential (CMAP) amplitudes and motor score is predictive of motor outcome after AVXS-101 (Onasemnogene Abeparvovec) SMA therapy.

Spinal muscular atrophy 1 (SMA1) is a severe early genetic disease with degeneration of motor neurons. Motor development is still suboptimal after gene replacement therapy in symptomatic patients. In this study, compound muscle action potential (CMAP) amplitudes were explored as predictors of motor recovery after gene therapy.

Development and co-construction of a therapeutic patient education program for albinism.

Background: Long-term and ongoing support in accordance with the changing needs of patients and their families is one of the main components of patient care, including therapeutic patient education (TPE).

Objective: To co-construct a TPE program for albinism with all those involved in the management of albinism patients.

Methods: Eight steps have been defined for the co-construction process: 1) identify all the relevant experts and invite them to participate in the construction of a TPE program to improve care for and support of patients with albinism, 2) review and analyse all publications regarding TPE for albinism, 3) conduct semi-structured interviews with the patients' parents, 4) conduct brainstorming meetings with the participating experts for an exchange of experience and expertise, 5) elaborate the program's concrete content with the experts, 6) draw up a TPE skills checklist, 7) create TPE educational tools to facilitate learning, 8) review and summarize each step of the co-construction protocol.

Palliative Care in SMA Type 1: A Prospective Multicenter French Study Based on Parents' Reports.

Spinal muscular atrophy type 1 (SMA-1) is a severe neurodegenerative disorder, which in the absence of curative treatment, leads to death before 1 year of age in most cases. Caring for these short-lived and severely impaired infants requires palliative management. New drugs (nusinersen) have recently been developed that may modify SMA-1 natural history and thus raise ethical concerns about the appropriate level of care for patients.
