Hidden Trauma: An Analysis of the Identification of Contusions on Different Skin Tones.

While abrasions and lacerations are typically easily identified, darker pigmentation of the skin may obscure contusions. Forensic pathology literature shows a disproportionate number of illustrations of contusions on lighter skin tones compared to darker ones. Skin and soft tissue dissection is the most reliable method to confirm contusions.

Fascin structural plasticity mediates flexible actin bundle construction.

Fascin cross-links actin filaments (F-actin) into bundles that support tubular membrane protrusions including filopodia and stereocilia. Fascin dysregulation drives aberrant cell migration during metastasis, and fascin inhibitors are under development as cancer therapeutics. Here, we use cryo-EM, cryo-electron tomography coupled with custom denoising and computational modeling to probe human fascin-1's F-actin cross-linking mechanisms across spatial scales.

Contemporary Administrative Codes to Identify Pulmonary Vein Isolation Procedures for Atrial Fibrillation.

Background: Use of pulmonary vein isolation (PVI) to treat atrial fibrillation continues to increase. Despite great interest in leveraging administrative data for real-world analyses, contemporary procedural codes for identifying PVI have not been evaluated.

Methods And Results: In this observational retrospective cohort study, inpatient PVIs were identified among US Medicare fee-for-service beneficiaries using Current Procedural Terminology (CPT) code 93656 in Carrier Line Files.

Phosphoribosyl pyrophosphate synthetase 1 () associated retinal degeneration: an international study.

Introduction: Phosphoribosyl pyrophosphate synthetase 1 () is an X-linked gene critical for nucleotide metabolism. Pathogenic variants cause three overlapping phenotypes: Arts syndrome (severe neurological disease), Charcot-Marie-Tooth type 5 [CMTX5] (peripheral neuropathy), and non-syndromic sensorineural hearing loss (SNHL). Each may be associated with retinal dystrophy.

Social Determinants of Health Affecting Retinopathy of Prematurity Follow-up Attendance.

Purpose: To identify social determinants of health (SDOH) associated with follow-up attendance of pre-term infants with retinopathy of prematurity (ROP) after neonatal intensive care unit (NICU) discharge.

Methods: This retrospective cohort study, conducted at a single academic tertiary care center, included preterm infants screened for ROP from July 2018 to December 2022. Sociodemographic and clinical data were collected from a preexisting NICU database.
