Virtual reality use in pediatric patients for orthopedic clinical procedures: A randomized prospective trial of efficacy.

Background: Distraction therapy use such as virtual reality is novel in the pediatric orthopedic field. In this study, we use subjective and objective metrics to evaluate virtual reality efficacy to reduce anxiety and pain in a pediatric orthopedic cohort.

Methods: A prospective randomized controlled trial included patients between age 5 and 17 years, presenting to a tertiary care pediatric orthopedic clinic.

Elasto-compliance of harmonically stimulated soft micro-gaps during electro-magneto-kinetic flows.

In this article, we develop and solve an analytical model to understand the elasto-hydrodynamic force response of a deformable, soft substrate, under dynamic loading; wherein the microfluidic gap between the substrate and load is subjected to electro-magneto-hydrodynamic interactions. As a simple physical system, we model the coupled fluid-structure-interaction characteristics when a rigid, small cylinder is permitted to impinge harmonically on an infinitely large elastic, soft substrate, and an oscillatory, squeeze flow establishes in the micro-gap formed between the two. We discuss the different observations and mechanics in terms of the governing Dukhin, Hartmann, and electroviscous numbers.

Identifying solutions to minimize meal tray waste: A mixed-method approach.

Background & Aims: Over $150,000 are lost annually due to meal tray waste in a large hospital in the United States. This study aims to explore the root causes of meal tray waste within a decentralized foodservice model and strategies to mitigate waste.

Methods: A mixed methods sequential explanatory design was used by first identifying hospital units high and low in meal tray waste using recorded food management data from January 2021 through September 2022, then conducting observations, mobile-interviews (n = 16), and in-depth interviews with hospital foodservice staff (n = 6) and nurses (n = 6) in each unit.

What Is Medical Extended Reality? A Taxonomy Defining the Current Breadth and Depth of an Evolving Field.

Medical extended reality (MXR) has emerged as a dynamic field at the intersection of health care and immersive technology, encompassing virtual, augmented, and mixed reality applications across a wide range of medical disciplines. Despite its rapid growth and recognition by regulatory bodies, the field lacks a standardized taxonomy to categorize its diverse research and applications. This American Medical Extended Reality Association guideline, authored by the editorial board of the , introduces a comprehensive taxonomy for MXR, developed through a multidisciplinary and international collaboration of experts.

Prescription Drug Prices: An AAN Position Statement.

This position statement serves to establish the AAN's stance on the methods to address the cost of prescription drugs being considered by state and federal policymakers so that the AAN can continue to advocate effectively for its members. Neurologists seek to provide high-value care for patients with neurologic diseases at the lowest cost possible. However, many therapies for neurologic diseases are among the most expensive in the United States.

Three-Dimensional Visualization With Virtual Reality Facilitates Complex Live Donor Renal Transplant.

Living donor renal transplant involves highly technical operations in both a healthy donor and a recipient with end-stage kidney disease. Contrast-enhanced computed tomography angiography (CTA) is used to assess critical donor anatomy, but its interpretation becomes increasingly difficult as renal anatomy becomes more complex. A related donor was denied because of prohibitive anatomy seen on the pretransplant evaluation CTA.

Guidelines for establishing a 3-D printing biofabrication laboratory.

Advanced manufacturing and 3D printing are transformative technologies currently undergoing rapid adoption in healthcare, a traditionally non-manufacturing sector. Recent development in this field, largely enabled by merging different disciplines, has led to important clinical applications from anatomical models to regenerative bioscaffolding and devices. Although much research to-date has focussed on materials, designs, processes, and products, little attention has been given to the design and requirements of facilities for enabling clinically relevant biofabrication solutions.

3D printed bismuth oxide-polylactic acid composites for radio-mimetic computed tomography spine phantoms.

Polylactic acid (PLA) composite filaments with varying concentrations of bismuth oxide microparticle additives were fabricated for use with commercially available fused filament fabrication (FFF) printing systems for the production of spine phantoms that mimic the radiopacity of bone. Thermal analysis showed that the additives had limited impact on the glass transition temperature and melting point of the filaments, allowing for their use in commercial FFF systems with standard printer settings. The ultimate strength of the printed test specimens was found to reduce slightly when bismuth oxide was added in high concentrations, with a moderate reduction of 12% compared to PLA at the highest concentration of 30 wt%.

Three-Dimensional Printed Patient Models for Complex Pediatric Spinal Surgery.

Pediatric spinal deformity surgeries are challenging operations that require considerable expertise and resources. The unique anatomy and rarity of these cases present challenges in surgical training and preparation. We present a case series illustrating how 3-dimensional (3-D) printed models were used in preoperative planning for 3 cases of pediatric spinal deformity surgery.

Repetitive Transcranial Magnetic Stimulation for Treatment of Depression in a Patient With Severe Traumatic Brain Injury.

Background: Traumatic brain injury (TBI) commonly presents with a constellation of findings, including physical, cognitive, and psychological disturbances. Traditionally, few options have been available for long-term management of mood symptoms for post-TBI patients who are refractory to medications. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment.

Computed tomography characteristics in pediatric versus adult traumatic brain injury.

Object: Traumatic brain injury (TBI) is a leading cause of injury, hospitalization, and death among pediatric patients. Admission CT scans play an important role in classifying TBI and directing clinical care, but little is known about the differences in CT findings between pediatric and adult patients. The aim of this study was to determine if radiographic differences exist between adult and pediatric TBI.

Risk of unfavorable long-term outcome in older adults with traumatic intracranial hemorrhage and anticoagulant or antiplatelet use.

Study Objective: The objective was to compare neurological outcomes at 6 months in older patients with preinjury warfarin or clopidogrel use and mild traumatic intracranial hemorrhage with those without prior use of these medications.

Methods: This was a retrospective study conducted at a Level 1 trauma center from April 2009 to July 2010. Patients older than 55 years with isolated mild head injury (Glasgow Coma Scale score 13-15 and Abbreviated Injury Score < 3 in nonhead body region) were included.
