Humans Continue to Outperform Large Language Models in Complex Clinical Decision-Making: A Study with Medical Calculators.

Although large language models (LLMs) have been assessed for general medical knowledge using medical licensing exams, their ability to effectively support clinical decision-making tasks, such as selecting and using medical calculators, remains uncertain. Here, we evaluate the capability of both medical trainees and LLMs to recommend medical calculators in response to various multiple-choice clinical scenarios such as risk stratification, prognosis, and disease diagnosis. We assessed eight LLMs, including open-source, proprietary, and domain-specific models, with 1,009 question-answer pairs across 35 clinical calculators and measured human performance on a subset of 100 questions.

Comparison of the GoCheck Kids and Spot Screener photoscreening devices for the detection of amblyopia risk factors using 2021 AAPOS recommendations.

Purpose: To compare the Spot Vision Screener (SPOT) to the GoCheck Kids mobile application (GCK) in the evaluation of amblyopia risk factors (ARFs), according to updated 2021 AAPOS guidelines for instrument-based pediatric vision screening.

Methods: SPOT, GCK using horizontal and vertical images (two-photo mode), and a complete eye examination (CEE) were performed on children ages ≥1 to <7 years referred to a pediatric ophthalmologist from October 2020 to December 2022 for a failed vision screen based on manufacturer guidelines. The primary outcomes were sensitivity, specificity, and positive predictive value (PPV) for each photoscreener.

Five-year evaluation of Anal Cancer Screening Program in Men Who Have Sex With Men with HIV at Two Academic Center Clinics.

Background: Guidelines recommend annual anal cytology-based squamous cell carcinoma of anus (SCCA) screening for men who have sex with men (MSM) with HIV aged ≥35 years (eligible population). Recommended threshold for high resolution anoscopy (HRA) depends on its availability: low-threshold (any abnormal cytology) if availability is high, and high-threshold (High-Grade Squamous Intraepithelial Lesion (HSIL) on cytology) if availability is low.

Methods: Retrospective chart review (2018-2022) at academic HIV clinics.

Tissue expansion mitigates radiation-induced skin fibrosis in a porcine model.

Tissue expansion (TE) is the primary method for breast reconstruction after mastectomy. In many cases, mastectomy patients undergo radiation treatment (XR). Radiation is known to induce skin fibrosis and is one of the main causes for complications during post-mastectomy breast reconstruction.

Mitonuclear effects on sex ratio persist across generations in interpopulation hybrids.

Eukaryotic energy production requires tight coordination between nuclear and mitochondrial gene products. Because males and females often have different energetic strategies, optimal mitonuclear coordination may be sex-specific. Previous work found evidence for sex-specific mitonuclear effects in the copepod Tigriopus californicus by comparing two parental lines and their reciprocal F1 crosses.
