A qualitative study exploring the feasibility and acceptability of embedding an overdose prevention sites in a U.S. hospital.

Introduction: Community-based overdose prevention sites (OPS) are recognized for reducing overdose deaths and the spread of HIV and hepatitis C among people who use drugs (PWUD). While some hospitals in Europe and Canada have successfully integrated OPS into their facilities, such integration remains illegal in the United States. This study explores the feasibility and acceptability of implementing an OPS at the Hospital of the University of Pennsylvania (HUP), situated in an urban area with high rates of overdose.

Wound Characteristics Among Patients Exposed to Xylazine.

Importance: The alpha-2 agonist xylazine is increasingly detected as an adulterant in illicitly manufactured fentanyl. There is concern that xylazine may be responsible for an emerging pattern of necrotizing wounds among people who use drugs, but the clinical features of wounds associated with xylazine remain poorly characterized.

Objective: To systematically characterize the location, wound bed surface, and chronicity of wounds among persons with confirmed xylazine exposure.

Depth-resolved characterization of Meissner screening breakdown in surface treated niobium.

We report direct measurements of the magnetic field screening at the limits of the Meissner phase for two superconducting niobium (Nb) samples. The samples are processed with two different surface treatments that have been developed for superconducting radio-frequency (SRF) cavity applications-a "baseline" treatment and an oxygen-doping ("O-doping") treatment. The measurements show: (1) that the screening length is significantly longer in the "O-doping" sample compared to the "baseline" sample; (2) that the screening length near the limits of the Meissner phase increases with applied field; (3) the evolution of the screening profile as the material transitions from the Meissner phase to the mixed phase; and (4) a demonstration of the absence of any screening profile for the highest applied field, indicative of the full flux entering the sample.

A multicenter evaluation of the time and travel burden on families with children treated for early-onset scoliosis.

Purpose: Patients who undergo growth-friendly (GF) treatment for early-onset scoliosis (EOS) undergo multiple clinical and surgical encounters. We sought to quantify the associated temporal and travel burden and estimate subsequent cost.

Methods: Four centers in an international study group combined data on EOS patients who underwent surgical GF treatment from 2006 to 2021.

Adaptive Biobehavioral Control: A Pilot Analysis of Human-Machine Coadaptation in Type 1 Diabetes.

While it is well recognized that an automated insulin delivery (AID) algorithm should adapt to changes in physiology, it is less understood that the individual would also have to adapt to the AID system. The adaptive biobehavioral control (ABC) method presented here attempts to compensate for this deficiency by including AID into an information cloud-based ecosystem. The Web Information Tool (WIT) implements the ABC concept via the following: (1) a Physiological Adaptation Module (PAM) that tracks metabolic changes and adapts AID parameters accordingly and (2) a Behavioral Adaptation Module (BAM) that provides information feedback.
