Aims: Duodenal Mucosal Resurfacing (DMR) is an endoscopic ablation technique aimed at improving glycemia in patients with type 2 diabetes mellitus (T2DM). Although the exact underlying mechanism is still unclear, it is postulated that the DMR-induced improvements are the result of changes in the duodenal mucosa. For this reason, we assessed macroscopic and microscopic changes in the duodenal mucosa induced by DMR + GLP-1RA.

Introduction: Radiological scores used to assess the extent of subarachnoid hemorrhage are limited by intrarater and interrater variability and do not utilize all available information from the imaging. Image segmentation enables precise identification and delineation of objects or regions of interest and offers the potential for automatization of score assessments using precise volumetric information. Our study aims to develop a deep learning model that enables automated multiclass segmentation of structures and pathologies relevant for aneurysmal subarachnoid hemorrhage outcome prediction.

Introduction: Prediction scores for hematoma expansion in spontaneous intracerebral hemorrhage (ICH), such as the 9-point and BRAIN scores, were developed predominantly using planimetry to measure hematoma volume. In this study, we aim to investigate whether the ABC/2 formula, which is known to overestimate hematoma volume, can be reliably used as a substitute for planimetry in these prediction scores.

Patients And Methods: A total of 429 patients from four hospitals were retrospectively enrolled.

Article Synopsis
  • Childhood obesity is increasingly recognized as a significant global health issue, with environmental influences playing a role in its development.
  • A study involving 63 adolescents examined pupillary responses to auditory food vs. nonfood words, using a remote eye-tracking device to measure changes in pupil size.
  • Results showed that healthy-weight adolescents exhibited greater pupil dilation to food words compared to those with obesity, who had a similar response to both food and nonfood cues; this suggests the need to explore psychological factors affecting these responses in future research.
