Citric acid is more effective than sodium thiosulfate in chelating calcium in a dissolution model of calcinosis.

Calcinosis cutis affects 20-40% of patients with systemic sclerosis. This study tests the hypothesis that calcium-chelating polycarboxylic acids can induce calcium dissolution without skin toxicity or irritancy. We compared citric acid (CA) and ethylenediaminetetraacetic acid (EDTA) to sodium thiosulfate (STS) for their ability to chelate calcium in vitro using a pharmaceutical dissolution model of calcinosis (hydroxyapatite (HAp) tablet), prior to evaluation of toxicity and irritancy in 2D in vitro skin models.

Relationship of Individual Athlete External Load, Session Rating of Perceived Exertion, and Athlete Playing Status Across a Collegiate Women's Basketball Season.

External (EL) and internal (IL) load are commonly used methods used to quantify training load in team sports. Playing time and playing position may influence the training loads for specific athletes throughout a season. The purpose of the current study was to evaluate the effect of athlete playing status and individual in-season practices on EL and IL across a collegiate women's basketball season.

Mitochondrial dysfunction signatures in idiopathic primary male infertility: a validated proteomics-based diagnostic approach.

Research Question: Male infertility accounts for almost half of all infertility cases worldwide, with idiopathic male infertility accounting for up to 30% of the cases. Sperm proteomics has revealed critical molecular pathway changes in men with infertility. However, the sperm mitochondrial proteome remains poorly understood.

What If…The Impact of Institutional Accreditation on PA Programs Transitioning to an Entry-Level Professional Doctorate Degree.

Introduction: There are several ramifications of a potential degree transition to an entry-level doctoral degree for Physician Assistant (PA) programs. The purpose of this article is to investigate the impact on institutional accreditation and transitioning to an entry level doctoral degree. To understand the potential impact on racial diversity, a subset of programs was further reviewed.

Xylazine-Associated Necrotic Upper-Extremity Wounds: A Single Hospital System's Experience with 82 Patients and 125 Wounds.

Background: The rise in xylazine-adulterated heroin and fentanyl poses novel challenges to hand surgeons and a rising epidemic of necrotic upper-extremity wounds. While prior case studies have focused on particularly severe and complex xylazine-associated necrotic (XAN) wounds, the aim of this consecutive case series was to characterize the variability of presentations (ranging from mild to severe) at a single institution at the epicenter of the xylazine epidemic.

Methods: Patients presenting to a tertiary referral center for XAN upper-extremity wounds were retrospectively identified from emergency department visits and hospital admissions between January 2021 and December 2023.
