Comparison of Imaging Findings between Granulomatosis with Polyangiitis and Eosinophilic Granulomatosis with Polyangiitis on Sinus CT: Importance of High-Density Opacification of the Paranasal Sinuses.

Background And Purpose: Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA) are the most common causes of chronic sinusitis from systemic granulomatous diseases. While both are small- to medium-sized vasculitis with necrotizing granulomas, they have different clinical courses and prognoses. High-density sinus opacification has been reported in allergic fungal sinusitis with eosinophilic infiltrates.

Associations Between Food Restriction, Alcohol and Marijuana Use and Co-Use, and Consequences Among College Students.

Background: Simultaneous alcohol and marijuana use (SAM) and food restriction on days students intend to drink are associated with an increased risk of substance use-related consequences. However, these negative outcomes have been studied mostly in alcohol-only use contexts. Little is known about the combination of alcohol, marijuana, SAM, and food restriction.

Artificial intelligence in emergency and trauma radiology: ASER AI/ML expert panel Delphi consensus statement on research guidelines, practices, and priorities.

Background: Emergency/trauma radiology artificial intelligence (AI) is maturing along all stages of technology readiness, with research and development (R&D) ranging from data curation and algorithm development to post-market monitoring and retraining.

Purpose: To develop an expert consensus document on best research practices and methodological priorities for emergency/trauma radiology AI.

Methods: A Delphi consensus exercise was conducted by the ASER AI/ML expert panel between 2022-2024.

Evolution and development of complex floral displays.

Flowering plants - angiosperms - display an astounding diversity of floral features, which have evolved in response to animal pollination and have resulted in the most species-rich plant clade. Combinations of macroscale (e.g.
