Validity Evidence for Using Virtual, Interactive Patient Encounters to Teach and Assess Clinical Reasoning for First-Year Medical Students.

Purpose: Despite universal agreement on the importance of clinical reasoning skills, inadequate curricular attention to these skills remains a problem. To facilitate integration of clinical reasoning instruction and assessment into the preclerkship phase, the authors created a clinical reasoning curriculum using technology-enhanced patient simulations.

Method: In 2023, first-year medical students at Duke University School of Medicine were enrolled in a biomedical science course using diagnostic reasoning sessions and 16 virtual, interactive patient (VIP) encounters to teach and assess clinical reasoning.

Preclinical Evaluation of Bavdegalutamide (ARV-110), a Novel PROteolysis TArgeting Chimera Androgen Receptor Degrader.

Androgen receptor (AR) signaling is the principal driver of prostate cancer, and drugs that target this pathway (e.g., abiraterone and enzalutamide) are standard treatments for metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer (mCRPC).

Bryozoa (Cheilostomata) from polymetallic nodules in the Russian exploration area, Clarion-Clipperton Fracture Zone, eastern Pacific Ocean-taxon novelty and characteristics as macro- and megafaunal elements.

This work describes Bryozoa of the order Cheilostomata associated with polymetallic nodules collected by box-coring in the eastern part of the Russian exploration area of the Clarion-Clipperton Fracture Zone (CCFZ or CCZ) under contract to Yuzhmorgeologiya. Study of 569 cheilostome specimens from 4510-5280 m depth yielded 32 species (22 new) in 20 genera (3 new) and 14 families (1 new). For six species, the nomenclature was left open (genus only) owing to the paucity of defining characters.

Morphological and Mechanical Property Differences in Trapeziometacarpal Ligaments of Healthy and Osteoarthritic Female Joints.

Purpose: To identify changes in morphological and mechanical properties in the volar ligament complex (VLC), dorsoradial ligaments (DRL), and posterior oblique ligaments (POL) in healthy and osteoarthritic female trapeziometacarpal (TMC) joints.

Methods: Twenty-four fresh-frozen female cadaveric TMCs were separated into (1) younger healthy/early-stage osteoarthritic, (2) elder healthy/early-stage osteoarthritic, and (3) advanced-stage osteoarthritic groups based on age and Eaton-Littler grading. Stress relaxation and load-to-failure testing were performed to characterize mechanical tensile properties.
