Innovative Real-World Data Use for Identifying Stroke Survivors and Access to Rehabilitation in Primary Care in Brazil.

Background: As the impact of stroke remains, primary healthcare will continue to be a critical platform managing the poststroke journey. We aimed to identify stroke survivors assisted by community health worker in Brazil and how they relate to the location of rehabilitation facilities locations.

Methods: We developed a cross-sectional study using deidentified data from a real-world database generated by a free data collection app used by community health workers from May 2015 to January 2021 in Brazil to identify stroke survivors and to assess demographics and clinical characteristics.

A limb-girdle muscular dystrophy 2I model of muscular dystrophy identifies corrective drug compounds for dystroglycanopathies.

Zebrafish are a powerful tool for studying muscle function owing to their high numbers of offspring, low maintenance costs, evolutionarily conserved muscle functions, and the ability to rapidly take up small molecular compounds during early larval stages. Fukutin-related protein (FKRP) is a putative protein glycosyltransferase that functions in the Golgi apparatus to modify sugar chain molecules of newly translated proteins. Patients with mutations in the FKRP gene can have a wide spectrum of clinical symptoms with varying muscle, eye, and brain pathologies depending on the location of the mutation in the FKRP protein.

A defect in the RNA-processing protein HNRPDL causes limb-girdle muscular dystrophy 1G (LGMD1G).

Limb-girdle muscular dystrophies (LGMD) are a heterogeneous group of genetically determined muscle disorders with a primary or predominant involvement of the pelvic or shoulder girdle musculature. More than 20 genes with autosomal recessive (LGMD2A to LGMD2Q) and autosomal dominant inheritance (LGMD1A to LGMD1H) have been mapped/identified to date. Mutations are known for six among the eight mapped autosomal dominant forms: LGMD1A (myotilin), LGMD1B (lamin A/C), LGMD1C (caveolin-3), LGMD1D (desmin), LGMD1E (DNAJB6), and more recently for LGMD1F (transportin-3).

Dystrophic muscle improvement in zebrafish via increased heme oxygenase signaling.

Duchenne muscular dystrophy (DMD) is caused by a lack of the dystrophin protein and has no effective treatment at present. Zebrafish provide a powerful in vivo tool for high-throughput therapeutic drug screening for the improvement of muscle phenotypes caused by dystrophin deficiency. Using the dystrophin-deficient zebrafish, sapje, we have screened a total of 2640 compounds with known modes of action from three drug libraries to identify modulators of the disease progression.

Characterization of zebrafish dysferlin by morpholino knockdown.

Mutations in the gene encoding dysferlin cause two distinct muscular dystrophy phenotypes: limb-girdle muscular dystrophy type 2B (LGMD-2B) and Miyoshi myopathy (MM). Dysferlin is a large transmembrane protein involved in myoblast fusion and membrane resealing. Zebrafish represent an ideal animal model to use for studying muscle disease including abnormalities of dysferlin.
