The region of St. Louis, Missouri, has displayed a high level of heterogeneity in COVID-19 cases, hospitalization, and vaccination coverage. We investigate how human mobility, vaccination, and time-varying transmission rates influenced SARS-CoV-2 transmission in five counties in the St. Louis area. A COVID-19 model with a system of ordinary differential equations was developed to illustrate the dynamics with a fully vaccinated class. Using the weekly number of vaccinations, cases, and hospitalization data from five counties in the greater St. Louis area in 2021, parameter estimation for the model was completed. The transmission coefficients for each county changed four times in that year to fit the model and the changing behaviour. We predicted the changes in disease spread under scenarios with increased vaccination coverage. SafeGraph local movement data were used to connect the forces of infection across various counties.

Background: Relapsed or refractory cases of pediatric acute myeloid leukemia (AML) have poor outcomes despite advancements in chemotherapy and hematopoietic stem cell transplantation (HSCT). While a second HSCT is often a salvage option, its outcomes vary widely, and prognostic factors remain unclear.
Objectives: This study aimed to evaluate outcomes and identify prognostic factors in pediatric patients with AML who underwent multiple HSCTs.

Objective: To evaluate the clinical efficacy of tocilizumab, a interleukin-6 (IL-6) receptor blocker, for the treatment of acute necrotizing encephalopathy (ANE).
Methods: PubMed, Cochrane Library, Embase, and Web of Science were searched for systematic review based on PRISMA guidelines. ANE patients treated with and without tocilizumab were included.

Background: Respiratory syncytial virus (RSV) is a leading cause of respiratory infections in infants and young children. The COVID-19 pandemic significantly disrupted global RSV epidemiology. This study aimed to investigate the impact of the pandemic on RSV epidemiology in northern Taiwan from 2018 to 2023.

Purpose: This study aimed to evaluate the performance of ChatGPT (GPT-4o) in interpreting free-text breast magnetic resonance imaging (MRI) reports by assigning BI-RADS categories and recommending appropriate clinical management steps in the absence of explicitly stated BI-RADS classifications.
Methods: In this retrospective, single-center study, a total of 352 documented full-text breast MRI reports of at least one identifiable breast lesion with descriptive imaging findings between January 2024 and June 2025 were included in the study. Incomplete reports due to technical limitations, reports describing only normal findings, and MRI examinations performed at external institutions were excluded from the study.

Intra-aneurysmal thrombus formation is crucial for the healing of endovascularly treated aneurysms. This study evaluated whether T1-weighted black blood imaging can monitor thrombus formation by examining the relationship between chronological signal intensity changes and aneurysm occlusion status after flow diverter stenting and coil embolization. We retrospectively analyzed 78 patients with 83 aneurysms (flow diverter stenting: 28, coil embolization: 55) who underwent T1-weighted black blood imaging at 1 week, 3 months, and 6 months post-treatment.
