Objective: To determine the tolerance to and benefits of an intensive mobility training (IMT) approach for individuals with incomplete spinal cord injury (ISCI).
Design: Prospective pretest-posttest study with 6-month follow-up.
Setting: University research laboratory.
Participants: A volunteer sample of individuals with ISCI (N=15; >6 mo postinjury and able to walk at least 3.05 m with or without assistance). Follow-up data were collected for 10 of the participants.
Interventions: Participants received IMT for 3h/d for 10 weekdays, participating in activities that encouraged repetitive, task-specific training of their lower extremities in a massed practice schedule.
Main Outcome Measures: Amount of time spent in therapeutic activities and rest was used to assess participants' tolerance to the intervention. Treatment outcomes were assessed pretest, posttest, and 6 months after the intervention and included the Berg Balance Scale (BBS), Dynamic Gait Index (DGI), 6-minute walk test, gait speed, and Spinal Cord Injury Functional Ambulation Inventory.
Results: Individuals in the higher functioning ISCI group (BBS score ≥45 and gait speed ≥0.6 m/s) spent more time in the intensive therapy on average than individuals in the lower functioning ISCI group. Effect sizes were comparable for changes in balance and mobility assessments between the lower and higher functioning groups, with the largest effect sizes observed for the DGI.
Conclusions: This dosage of IMT may be a more appropriate treatment approach for higher functioning ISCI individuals, as they were better able to tolerate the length of the session and demonstrated higher effect sizes postintervention.

Chrysoeriol (CHE) is a naturally occurring compound with established anti-inflammatory and anti-tumor effects. This study examines its potential role in regulating osteoclast differentiation and activity, both of which are crucial for bone remodeling. Computational docking revealed high binding affinity between CHE and RANKL, specifically at the Lys-181 residue of RANKL, suggesting potential inhibitory interactions on osteoclastogenesis.

Mutations in the ANXA11 gene, encoding an RNA-binding protein, have been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS), but the underlying in vivo mechanisms remain unclear. This study examines the clinical features of ALS patients harboring the ANXA11 hotspot mutation p.P36R, characterized by late-onset motor neuron disease and occasional multi-system involvement.

Introduction: Ultrasound is important in heart diagnostics, yet implementing effective cardiac ultrasound requires training. While current strategies incorporate digital learning and ultrasound simulators, the effectiveness of these simulators for learning remains uncertain. This study evaluates the effectiveness of simulator-based versus human-based training in Focused Assessed with Transthoracic Echocardiography (FATE).

Background: Vanishing white matter disease (VWMD) is a rare autosomal recessive leukoencephalopathy. It is typified by a gradual loss of white matter in the brain and spinal cord, which results in impairments in vision and hearing, cerebellar ataxia, muscular weakness, stiffness, seizures, and dysarthria cogitative decline. Many reports involve minors.

Introduction: The Mirabegron-anticholinergic (MAC) combination has proven effective as a step-up strategy in managing paediatric neurogenic bladder following anticholinergic medication and botulinum toxin (BTX) therapy. This study assesses the long-term efficacy of MAC in children with neurogenic bladder.
Patients And Methods: A retrospective chart review was conducted from 2015 to 2023, including consecutive paediatric patients receiving Mirabegron (25/50 mg) with an anticholinergic agent (solifenacin 16, tolterodine 7, oxybutynin 7, trospium 1).
