Discordance between MR enterography and endoscopic detection of Crohn's disease ileal strictures: evidence to inform recommendations.
Abdom Radiol (NY)
December 2024
Mayo Clinic, Rochester, USA.
Purpose: To evaluate correlation between terminal ileal (TI) stricture diagnosis at MR enterography (MRE) and ileocolonoscopy (IC) in patients with Crohn's disease (CD).
Methods: One hundred and four patients with CD (51% females; 41 ± 15 years) underwent IC and MRE within 3 months in this retrospective case-control study. Positive cases had TI strictures diagnosed by endoscopy (n = 35); or MRE (threshold small bowel dilation ≥ 3cm; n = 34).
Interplay between platelets and coagulation: from protective haemostasis to pathological arterial thrombosis.

Haemostasis refers to the physiological process aimed at repairing vessel injury and preventing bleeding. It involves four interlinked stages culminating in the formation of a platelet-fibrin haemostatic plug that is eventually dissolved once the vessel heals. In contrast, arterial thrombosis is a pathological condition resulting from atheroma exposure, triggering the formation of a platelet-rich thrombus that may obstruct blood flow, leading to the clinical manifestations of ischaemic cardiovascular disease.

Aim: Bronchiectasis (BE) is a disease defined by irreversible dilatation of the airway. Computed tomography (CT) plays an important role in the detection and quantification of BE. The aim of this study was three-fold: 1) to assess bronchus-artery (BA) dimensions using fully automated software in a cohort of BE disease patients; 2) to compare BA dimensions with semi-quantitative BEST-CT (Bronchiectasis Scoring Technique for CT) scores for BE and bronchial wall thickening; and 3) to explore the structure-function relationship between BA-method lumen dimensions and spirometry outcomes.

School of Natural Sciences, Macquarie University, Sydney, Australia.
For the first time in any animal, we show that nocturnal bull ants use the exceedingly dim polarisation pattern produced by the moon for overnight navigation. The sun or moon can provide directional information via their position; however, they can often be obstructed by clouds, canopy, or the horizon. Despite being hidden, these bodies can still provide compass information through the polarised light pattern they produce/reflect.
