Metformin Use Is Inversely Associated with Prevalent, but Not Incident Colorectal Adenomas.

Background: Chemoprevention for colorectal neoplasia has attracted growing interest, with multiple medications investigated. Metformin may decrease the overall incidence of cancer in patients with diabetes and may decrease the incidence of colorectal cancer.

Aims: We aimed to determine the impact of metformin use on the behavior of colorectal adenomas in a US veteran population.

Respiratory Auscultation Lab Using a Cardiopulmonary Auscultation Simulation Manikin.

Introduction: Mastery of respiratory auscultation skills is fundamental for clinicians to develop. We created a case-based educational session utilizing a high-fidelity simulator to teach lung sound auscultation to medical students at our institution. We employed a hypothesis-driven approach and deliberate practice to enhance students' learning experience and retention of acquired skills.
