A spatial transcriptomic signature of 26 genes resolved at single-cell resolution characterizes high-risk gastric cancer precursors.

Gastric cancer precursors demonstrate highly-variable rates of progression toward neoplasia. Certain high-risk precursors, such as gastric intestinal metaplasia with advanced histologic features, may be at up to 30-fold increased risk for progression compared to lower-risk intestinal metaplasia. The biological differences between high- and low-risk lesions have been incompletely explored.

Neonatal deep medullary venous thrombosis radiographic severity is associated with neurodevelopmental impairment.

Deep medullary vein thrombosis (DMVT) is an increasingly recognized etiology of neonatal brain injury, but remains poorly understood. Our study aimed to assess the association between MRI severity and neurodevelopmental impairment (NDI) in neonates with DMVT, and develop a novel MRI grading system that might inform clinical outcomes. We retrospectively reviewed relevant charts from infants admitted to our tertiary care hospital between January 1990 to March 2023, and evaluated clinical characteristics, MRI features, and neurodevelopmental assessments of this cohort.

Applying Large Language Models to Assess Quality of Care: Monitoring ADHD Medication Side Effects.

Objective: To assess the accuracy of a large language model (LLM) in measuring clinician adherence to practice guidelines for monitoring side effects after prescribing medications for children with attention-deficit/hyperactivity disorder (ADHD).

Methods: Retrospective population-based cohort study of electronic health records. Cohort included children aged 6 to 11 years with ADHD diagnosis and 2 or more ADHD medication encounters (stimulants or nonstimulants prescribed) between 2015 and 2022 in a community-based primary health care network (n = 1201).

Use of a Stroke Alert Protocol and Outcomes at a Quaternary Children's Hospital.

Objective: To assess for improvement in diagnostic efficiency following implementation of an institutional pediatric stroke alert protocol at a quaternary children's hospital, and to compare characteristics of in-hospital (IH) and out-of-hospital (OH) stroke alert activations.

Study Design: We retrospectively reviewed data from pediatric stroke alerts called for children between age 1 month and 21 years of age at our quaternary children's hospital between October 2016 and October 2022 after implementation of an institutional stroke alert protocol. Generalized linear models assessed code-to-image (CTI) time over the study period, with and without interaction terms for alert location.

Leveraging a Large Language Model to Assess Quality-of-Care: Monitoring ADHD Medication Side Effects.

Objective: To assess the accuracy of a large language model (LLM) in measuring clinician adherence to practice guidelines for monitoring side effects after prescribing medications for children with attention-deficit/hyperactivity disorder (ADHD).

Methods: Retrospective population-based cohort study of electronic health records. Cohort included children aged 6-11 years with ADHD diagnosis and ≥2 ADHD medication encounters (stimulants or non-stimulants prescribed) between 2015-2022 in a community-based primary healthcare network (n=1247).
