Clinical Anatomy, EarlyView.ABSTRACT The esophagogastric junction (EGJ) is the anatomical zone where the esophagus ends and the stomach begins. Its competence in preventing gastro‐esophageal reflux has been shown to depend on a number of factors which have been extensively investigated and widely accepted.

Eye &ENT Research, EarlyView.ABSTRACT Artificial intelligence (AI) is increasingly applied to optical coherence tomography (OCT) in ophthalmology, but evidence for automated diagnosis is stronger than evidence for longitudinal monitoring. This narrative review evaluates OCT‐based AI with emphasis on disease monitoring and progression, particularly in retinal disease and glaucoma ...
