Lumbar Range of Motion Using the Wolfson Modified Schober Test.

Introduction: Lumbar range of motion (ROM) is a critical component of spinal function and often affected by age and sex. This study aimed to evaluate the variations in lumbar ROM across different age groups in a healthy adult population and determine the influence of sex, height, weight, and body mass index.

Methods: A total of 208 subjects (106 men, 102 women) were recruited and stratified into age groups from the 20s to 60s and older.

Hydraulic Polymethylmethacrylate Pressure Delivery System Versus Manual Balloon Tamp System in Balloon Kyphoplasty.

Study Design: Retrospective cohort study.

Objective: Osteoporotic vertebral compression fractures (VCFs) are prevalent among the elderly population, and Balloon kyphoplasty (BKP) is a minimally invasive solution for these. However, Polymethylmethacrylate (PMMA) leakage is a significant complication with potentially severe consequences.

A matched-pair case control study identifying hemodynamic predictors of cerebral aneurysm growth using computational fluid dynamics.

Initiation and progression of cerebral aneurysms is known to be driven by complex interactions between biological and hemodynamic factors, but the hemodynamic mechanism which drives aneurysm growth is unclear. We employed robust modeling and computational methods, including temporal and spatial convergence studies, to study hemodynamic characteristics of cerebral aneurysms and identify differences in these characteristics between growing and stable aneurysms. Eleven pairs of growing and non-growing cerebral aneurysms, matched in both size and location, were modeled from MRA and CTA images, then simulated using computational fluid dynamics (CFD).

Epidemiology of Species at a Tertiary Hospital in Southern Taiwan, 2012 to 2020: MLSA Phylogeny and Antimicrobial Susceptibility.

The identification and antimicrobial susceptibility of spp. are essential for guiding antibiotic treatment. We investigated the species distribution and evaluated the antimicrobial susceptibility of species collected in southern Taiwan from 2012 to 2020.

Validation of the Reduced Unified Continuum Formulation Against In Vitro 4D-Flow MRI.

We previously introduced and verified the reduced unified continuum formulation for vascular fluid-structure interaction (FSI) against Womersley's deformable wall theory. Our present work seeks to investigate its performance in a patient-specific aortic setting in which assumptions of idealized geometries and velocity profiles are invalid. Specifically, we leveraged 2D magnetic resonance imaging (MRI) and 4D-flow MRI to extract high-resolution anatomical and hemodynamic information from an in vitro flow circuit embedding a compliant 3D-printed aortic phantom.
