Medical educators are facing the new challenge of using medical simulation for teaching purposes. The use of simulators seems attractive for trainers and for trainees, but prices of simulators may be prohibitive. In an era of limited resources it is mandatory when using such an expensive tool as simulation, to prove its benefits. Despite the fact that simulation provides opportunity for training, additional advantages are far from being established. The supposed benefits of using medical simulators in teaching and examination needs to be proven regarding two aspects: effectiveness and efficiency.

Delta large-channel endoscopy versus unilateral biportal endoscopy decompressive laminectomy for lumbar spinal stenosis: a prospective randomized controlled trial.
J Orthop Surg Res
January 2025
Center of Medical Genetics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, 610041, China.
Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Pediatr Rheumatol Online J
January 2025
Division of Pediatric Rheumatology, Seattle Children's Hospital, 4800 Sand Point Way NE, Seattle, WA, 98105, USA.
Background: NSAIDs are commonly used as first line therapy in chronic nonbacterial osteomyelitis (CNO) but are not effective for all patients. The objective of this study was to identify clinical variables associated with NSAID monotherapy response versus requiring second-line medication in a single-center cohort of patients with CNO.
Methods: The charts of children with CNO who attended a CNO clinic at a quaternary care center between 1/1/05 and 7/31/21 were retrospectively reviewed.
Automatic segmentation of white matter lesions on multi-parametric MRI: convolutional neural network versus vision transformer.
BMC Neurol
January 2025
Department of Diagnostic Radiology, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, School of Medicine, College of Medicine, National Sun Yat-Sen University, No. 123 Ta-Pei Road, Niao-Sung Dist, Kaohsiung, 83305, Taiwan.
Background And Purpose: White matter hyperintensities in brain MRI are key indicators of various neurological conditions, and their accurate segmentation is essential for assessing disease progression. This study aims to evaluate the performance of a 3D convolutional neural network and a 3D Transformer-based model for white matter hyperintensities segmentation, focusing on their efficacy with limited datasets and similar computational resources.
Materials And Methods: We implemented a convolution-based model (3D ResNet-50 U-Net with spatial and channel squeeze & excitation) and a Transformer-based model (3D Swin Transformer with a convolutional stem).
Acute administration of NLX-101, a Serotonin 1A receptor agonist, improves auditory temporal processing during development in a mouse model of Fragile X Syndrome.

Graduate Neuroscience Program, University of California, Riverside, CA, USA.
Background: Fragile X syndrome (FXS) is a leading known genetic cause of intellectual disability and autism spectrum disorders (ASD)-associated behaviors. A consistent and debilitating phenotype of FXS is auditory hypersensitivity that may lead to delayed language and high anxiety. Consistent with findings in FXS human studies, the mouse model of FXS, the Fmr1 knock out (KO) mouse, shows auditory hypersensitivity and temporal processing deficits.

Hematopoietic stem cell transplantation (HSCT) is a highly effective therapy for malignant blood illnesses that pose a high risk, as well as diseases that are at risk due to other variables, such as genetics. However, the prevalence of graft-versus-host disease (GVHD) has impeded its widespread use. Ensuring the stability of microbial varieties and associated metabolites is crucial for supporting metabolic processes, preventing pathogen intrusion, and modulating the immune system.
