Concordance Between Trainee Self-Assessment and Expert Assessment of Cold Snare Polypectomy Competence: Results From a Randomized Clinical Study.

Purpose: Many trainees lack competence in performing cold snare polypectomy (CSP), and longer observation periods using assessment tools, such as the Cold Snare Polypectomy Assessment Tool (CSPAT), may be required. However, these tools are not commonly used in busy academic endoscopy practices. This study evaluates the concordance between trainee self-assessment of CSP with expert assessment and assesses factors associated with concordance.

Sex and race disparities in emergency department patients with chest pain and a detectable or mildly elevated troponin.

Background: Identifying and eliminating health disparities is a public health priority. The goal of this analysis is to determine whether cardiac testing or outcome disparities exist by race or sex in patients with detectable to mildly elevated serum troponin.

Methods: We conducted a secondary analysis of the CMR-IMPACT trial that randomized patients with symptoms suggestive of acute coronary syndrome and a detectable or mildly elevated troponin measure from 4 US hospitals to an early invasive angiography or cardiac MRI strategy.

Differential Associations of Cigar, Pipe, and Smokeless Tobacco Use Versus Combustible Cigarette Use With Subclinical Markers of Inflammation, Thrombosis, and Atherosclerosis: The Cross-Cohort Collaboration-Tobacco Working Group.

Background: Understanding the association of tobacco product use with subclinical markers is essential in evaluating health effects to inform regulatory policy. This is particularly relevant for noncigarette products (eg, cigars, pipes, and smokeless tobacco), which have been understudied because of their low prevalence in individual cohort studies.

Methods: This cross-sectional study included 98 450 participants from the Cross-Cohort Collaboration-Tobacco data set.

Evolving Trends and Patterns of Utilization of Magnetic Resonance-Guided Radiotherapy at a Single Institution, 2018-2024.

: Over the past decade, significant advances have been made in image-guided radiotherapy (RT) particularly with the introduction of magnetic resonance (MR)-guided radiotherapy (MRgRT). However, the optimal clinical applications of MRgRT are still evolving. The intent of this analysis was to describe our institutional MRgRT utilization patterns and evolution therein, specifically as an early adopter within a center endowed with multiple other technology platforms.

Scanner-based real-time three-dimensional brain + body slice-to-volume reconstruction for T2-weighted 0.55-T low-field fetal magnetic resonance imaging.

Background: Motion correction methods based on slice-to-volume registration (SVR) for fetal magnetic resonance imaging (MRI) allow reconstruction of three-dimensional (3-D) isotropic images of the fetal brain and body. However, all existing SVR methods are confined to research settings, which limits clinical integration. Furthermore, there have been no reported SVR solutions for low-field 0.
