Risk exists for civilian exposure to nerve agents (NA), and exposure can produce prolonged seizures. Pediatric populations are at greater risk for injury or death due to the central nervous system effects of NAs. To address the need to evaluate the effectiveness of anticonvulsants, pediatric and adult animal models were established to test the effectiveness of anticonvulsant drugs for treating NA-induced seizures in pediatric populations. In this paper, median effective dose (ED50) and neuroprotective effectiveness were determined for the first-line anticonvulsant treatments diazepam and midazolam in pediatric and adult rats against sarin- and VX-induced seizures. Comparisons between treatments were made across postnatal days (PND) 21, 28, and 70 in rats of both sexes. We observed high efficacy and potency of midazolam and diazepam, with low variation in doses across the ages or sexes. These data are important for informing adult and pediatric dosing recommendations for NA-induced seizures.

Background: Transition from paediatric to adult healthcare is a turning point for patients with Type 1 diabetes (T1D). A gradual coordinated process connecting paediatric and adult healthcare providers may improve adherence to adult follow-up.
Aims: To describe a transition process developed jointly by paediatric and adult diabetology units and compare patients progressing or not to follow-up in adult care setting.

The WOUND-Q is a patient-reported outcome measure for individuals with any type of chronic wound. This study aimed to identify patient and wound factors associated with the four WOUND-Q health-related quality of life (HRQL) scales: Life impact, Psychological, Sleep, and Social. Adults with a chronic wound were recruited internationally through clinical settings between August 2018 and May 2020, and through an online platform (i.

Miller Fisher syndrome (MFS) is a rare Guillain-Barré syndrome (GBS) variant. The global incidence of GBS is approximately one to two in 100,000 children (aged 0 to 15 years) per year. Miller Fisher syndrome represents a further small subset, with the incidence being one to two in 1,000,000 children.

Background: Cardiomyopathy is a disease that affects the myocardium and can be classified as dilated, restrictive, or hypertrophic cardiomyopathy. Among the subtypes, restrictive cardiomyopathy is characterized by restriction of ventricular filling and its uncommon cause is a disease due to mutation on Filamin C (FLNC) gene. Filamin C is an actin-binding protein encoded by FLNC gene and participates in sarcomere stability maintenance, which is expressed on the striated muscle.

The recently developed human brain organotypic culture model is one highly promising model that requires the involvement of neurosurgeons and neurosurgical patients. Studies have investigated the electrophysiological properties of neurons in such human tissues, but the maintenance of other cell types within explanted brain remains largely unknown.
