Evaluation of Prompts to Simplify Cardiovascular Disease Information Generated Using a Large Language Model: Cross-Sectional Study.

In this cross-sectional study, we evaluated the completeness, readability, and syntactic complexity of cardiovascular disease prevention information produced by GPT-4 in response to 4 kinds of prompts.

Super High Contrast USPIO-Enhanced Cerebrovascular Angiography Using Ultrashort Time-to-Echo MRI.

Background: Ferumoxytol (Ferahame, AMAG Pharmaceuticals, Waltham, MA) is increasingly used off-label as an MR contrast agent due to its relaxivity and safety profiles. However, its potent T2 relaxivity limits achievable T1-weighted positive contrast and leads to artifacts in standard MRI protocols. Optimization of protocols for ferumoxytol deployment is necessary to realize its potential.

Response of Unvaccinated US Adults to Official Information About the Pause in Use of the Johnson & Johnson-Janssen COVID-19 Vaccine: Cross-Sectional Survey Study.

Using a rapid response web-based survey, we identified gaps in public understanding of the Centers for Disease Control and Prevention's messaging about the pause in use of the Johnson & Johnson-Janssen COVID-19 vaccine and estimated changes in vaccine hesitancy using counterfactual questions.

Ferumoxytol-enhanced ultrashort TE MRA and quantitative morphometry of the human kidney vasculature.

Purpose: To evaluate the feasibility of Quantitative Ultrashort-Time-to-Echo Contrast-Enhanced (QUTE-CE) MRA using ferumoxytol as a contrast agent for abdominal angiography in the kidney.

Methods: Four subjects underwent ferumoxytol-enhanced MRA with the 3D UTE Spiral VIBE WIP sequence at 3 T. Image quality metrics were quantified, specifically the blood Signal-to-Noise Ratio (SNR), blood-tissue Contrast-to-Noise Ratio (CNR) and Intraluminal Signal Heterogeneity (ISH) from both the aorta and inferior vena cava (IVC).

Comparison of Readability of Official Public Health Information About COVID-19 on Websites of International Agencies and the Governments of 15 Countries.

This cross-sectional study evaluates the readability of information on COVID-19 on websites of international agencies, governments of 15 countries, and US health departments.

Chronic Medical Illness as a Risk Factor for Poor Mammography Screening Adherence.

The aim of this study was to determine the association between the presence of chronic medical disease and mammography screening adherence. We performed a retrospective study on women between the ages of 50 and 64 who received screening mammography in 2005 and had at least 8 years of follow-up. Demographic and clinical information was obtained from our centralized patient data registry.

Advanced imaging in acute and chronic deep vein thrombosis.

Deep venous thrombosis (DVT) affecting the extremities is a common clinical problem. Prompt imaging aids in rapid diagnosis and adequate treatment. While ultrasound (US) remains the workhorse of detection of extremity venous thrombosis, CT and MRI are commonly used as the problem-solving tools either to visualize the thrombosis in central veins like superior or inferior vena cava (IVC) or to test for the presence of complications like pulmonary embolism (PE).

Open access: the changing face of scientific publishing.

The debate on open access to scientific literature that has been raging in scholarly circles for quite some time now has been fueled further by the recent developments in the realm of the open access movement. This article is a short commentary on the current scenario, challenges, and the future of the open access movement.
