Hypoxic ischemic encephalopathy (HIE) is a brain injury that occurs in 1 ~ 5/1000 term neonates. Accurate identification and segmentation of HIE-related lesions in neonatal brain magnetic resonance images (MRIs) is the first step toward identifying high-risk patients, understanding neurological symptoms, evaluating treatment effects, and predicting outcomes. We release the first public dataset containing neonatal brain diffusion MRI and expert annotation of lesions from 133 patients diagnosed with HIE.

Methods: We conducted a cross-sectional survey of Children's Hospital Association pediatric surgical practices. Anonymous electronic surveys were used to investigate locum tenens utilization, primary reason for use, limitations on clinical activities, and variations in practice standards or quality.
Purpose: Investigate the influence of baseline blood pressure (BP) on retinal nerve fiber layer (RNFL) rates of change (RoC) in glaucoma patients with central damage or moderate to severe disease.
Design: Prospective cohort study.
Participants: 110 eyes with ≥4 RNFL optical coherence tomography scans and ≥2 years of follow-up.
Article Synopsis
- Acute kidney injury (AKI) affects a significant number of critically ill patients, with the lack of standardized tools for implementing KDIGO criteria creating challenges for researchers.
- The pyAKI pipeline was developed to address these issues, using the MIMIC-IV database to establish a standardized model for consistent AKI diagnosis.
- Validation tests showed that pyAKI performs better than human annotations, achieving perfect accuracy and offering a valuable resource for clinicians and data scientists in AKI research.
Article Synopsis
- MPS IIIB is a rare disorder caused by defects in the enzyme NAGLU, leading to brain dysfunction due to the accumulation of heparan sulfate in lysosomes.
- Researchers created a Drosophila (fruit fly) model with various NAGLU mutations to study the disorder's effects on activity and sleep patterns, revealing significant hyperactivity and sleep issues.
- The study found that gene expression changes in mutant flies are linked to problems with nervous system development and synaptic function, suggesting that this fly model could help develop future therapies for MPS IIIB.
