Comparative Analysis of Performance of Large Language Models in Urogynecology.

Importance: Despite growing popularity in medicine, data on large language models in urogynecology are lacking.

Objective: The aim of this study was to compare the performance of ChatGPT-3.5, GPT-4, and Bard on the American Urogynecologic Society self-assessment examination.

High-Risk Anomalous Aortic Origin of the Left Coronary Artery: Consecutive Admissions Presenting With Sudden Cardiac Arrest.

Anomalous aortic origin of the left coronary artery (AAOLCA) confers high risk for sudden cardiac arrest (SCA). This series aims to describe consecutive admissions with interarterial AAOLCA presenting with SCA and distinct clinical trajectories. An eight-year-old boy collapsed at school and received 10-min of cardiopulmonary resuscitation (CPR) and defibrillation prior to return of spontaneous circulation.

Imaging of 3 bright terrestrial gamma-ray flashes by the atmosphere-space interactions monitor and their parent thunderstorms.

The Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) includes an instrument designed to geolocate Terrestrial Gamma-ray Flashes (TGF) produced by thunderstorms. It does so with a coded aperture system shadowing the pixelated Low Energy Detector of the Modular X- and Gamma-ray Sensor (MXGS). Additionally, it locates associated lightning flashes with the Modular Multispectral Imaging Array (MMIA).

Disentangling top-down drivers of mortality underlying diel population dynamics of Prochlorococcus in the North Pacific Subtropical Gyre.

Photosynthesis fuels primary production at the base of marine food webs. Yet, in many surface ocean ecosystems, diel-driven primary production is tightly coupled to daily loss. This tight coupling raises the question: which top-down drivers predominate in maintaining persistently stable picocyanobacterial populations over longer time scales? Motivated by high-frequency surface water measurements taken in the North Pacific Subtropical Gyre (NPSG), we developed multitrophic models to investigate bottom-up and top-down mechanisms underlying the balanced control of Prochlorococcus populations.
