D-Dimer in Acute Mesenteric Venous Thrombosis: A Prospective Case-Control International Multicenter Study.

Background: Acute mesenteric venous thrombosis (MVT) is rarely suspected as primary diagnosis in emergency departments and still carries an in-hospital mortality rate of above 20%.

Objectives: The aim of this study was to find differences in clinical and laboratory markers between patients with acute MVT and a control group of suspected but confirmed as not having any type of acute mesenteric ischaemia (AMI).

Design: Data was retrieved from the AMESI (Acute MESenteric Ischaemia) study.

Edge-sharing water prisms.

Regular-shaped water clusters and nanostructures can be of particular interest for the self-assembly of complex structures and functional materials involving water molecules. Polyhedral water clusters are the most well studied. The low-energy structures of water hexamer, octamer and decamer are shaped like right prisms.

A Multi-Country Survey on the Availability of Intraoperative Use of Echocardiography for Noncardiac Surgery.

Background: This survey aimed to explore the availability and accessibility of echocardiography during noncardiac surgery worldwide.

Methods: An internet-based 45-item survey was sent, followed by reminders from August 30, 2021, to August 20, 2022.

Results: 1189 responses were received from 62 countries.

Incidence, diagnosis, management and outcome of acute mesenteric ischaemia: a prospective, multicentre observational study (AMESI Study).

Background: The aim of this multicentre prospective observational study was to identify the incidence, patient characteristics, diagnostic pathway, management and outcome of acute mesenteric ischaemia (AMI).

Methods: All adult patients with clinical suspicion of AMI admitted or transferred to 32 participating hospitals from 06.06.

Ice structures assembled from cubic water clusters of D and S symmetry.

The study of self-assembly processes is of key importance for fundamental science and modern technologies. Cubic water clusters of D and S symmetry show great potential as building blocks for self-assembly. The objective of this paper is to construct possible ice structures formed by hydrogen bonding of these very stable water clusters.
