"So we brought these players together": a qualitative study of educators' experiences to analyze the challenges of creating an e-learning program for neuropalliative care.

BACKGROUND: In recent years, the subspecialty of neuropalliative care has emerged with the goal of improving the quality of life of patients suffering from neurological disease, though gaps remain in neuropalliative care education and training. E-learning has been described as a way to deliver interactive and facilitated lower-cost learning to address global gaps in medical care. We describe here the development of a novel, international, hybrid, and asynchronous curriculum with both self-paced modules and class-based lectures on neuropalliative care topics designed for the neurologist interested in palliative care, the palliative care physician interested in caring for neurological patients, and any other physician or advanced care providers interested in neuropalliative care. METHODS: The course consisted of 12 modules, one per every four weeks, beginning July 2022. Each module is based on a case and relevant topics. Course content was divided into three streams (Neurology Basics, Palliative Care Basics, and Neuropalliative Care Essentials) of which two were optional and one was mandatory, and consisted of classroom sessions, webinars, and an in-person skills session. Evaluation of learners consisted of multiple choice questions and written assignments for each module. Evaluation of the course was based on semi-structured qualitative interviews conducted with both educator and learner, the latter of which will be published separately. Audio files were transcribed and underwent thematic analysis. For the discussion of the results, Khan's e-learning framework was used. RESULTS: Ten of the 12 participating educators were interviewed. Of the educators, three identified as mid-career and seven as senior faculty, ranging from six to 33 years of experience. Nine of ten reported an academic affiliation and all reported association with a teaching hospital. Themes identified from the educators' evaluations were: bridging the global gap, getting everybody on board, defining the educational scope, investing extensive hours of voluntary time and resources, benefiting within and beyond the curriculum, understanding the learner's experience, creating a community of shared learning, adapting future teaching and learning strategies, and envisioning long term sustainability. CONCLUSIONS: The first year of a novel, international, hybrid, and asynchronous neuropalliative care curriculum has been completed, and its educators have described both successes and avenues for improvement. Further research is planned to assess this curriculum from the learner perspective.

Regional variation of thigh muscle fat infiltration in patients with neuromuscular diseases compared to healthy controls.

BACKGROUND: Chemical shift encoding-based water-fat magnetic resonance imaging (CSE-MRI) measures a quantitative biomarker: the proton density fat fraction (PDFF). The aim was to assess regional and proximo-distal PDFF variations at the thigh in patients with myotonic dystrophy type 2 (DM2), limb-girdle muscular dystrophy type 2A (LGMD2A), and late-onset Pompe disease (LOPD) as compared to healthy controls. METHODS: Seven patients (n=2 DM2, n=2 LGMD2A, n=3 LOPD) and 20 controls were recruited. A 3D-spoiled gradient echo sequence was used to scan the thigh musculature. Muscles were manually segmented to generate mean muscle PDFF. RESULTS: In all three disease entities, there was an increase in muscle fat replacement compared to healthy controls. However, within each disease group, there were patients with a shorter time since symptom onset that only showed mild PDFF elevation (range, 10% to 20%) compared to controls (P≤0.05), whereas patients with a longer period since symptom onset showed a more severe grade of fat replacement with a range of 50% to 70% (P<0.01). Increased PDFF of around 5% was observed for vastus medialis, semimembranosus and gracilis muscles in advanced compared to early DM2. LGMD2A_1 showed an early disease stage with predominantly mild PDFF elevations over all muscles and levels (10.9%±7.1%) compared to controls. The quadriceps, gracilis and biceps femoris muscles showed the highest difference between LGMD2A_1 with 5 years since symptom onset (average PDFF 11.1%±6.9%) compared to LGMD2A_2 with 32 years since symptom onset (average PDFF 66.3%±6.3%). For LOPD patients, overall PDFF elevations were observed in all major hip flexors and extensors (range, 25.8% to 30.8%) compared to controls (range, 1.7% to 2.3%, P<0.05). Proximal-to-distal PDFF highly varied within and between diseases and within controls. The intra-reader reliability was high (reproducibility coefficient ≤2.19%). CONCLUSIONS: By quantitatively measuring muscle fat infiltration at the thigh, we identified candidate muscles for disease monitoring due to their gradual PDFF elevation with longer disease duration. Regional variation between proximal, central, and distal muscle PDFF was high and is important to consider when performing longitudinal MRI follow-ups in the clinical setting or in longitudinal studies.
