Diagnostic Performance of Clinical and Routine Laboratory Data in Acute Mesenteric Arterial Occlusion-An International Multicenter Study.

Background: There are no clinical or laboratory markers that can diagnose acute mesenteric ischemia (AMI) accurately. This study aimed to find differences in clinical and laboratory markers between arterial occlusive AMI and other acute abdominal diseases where AMI was initially suspected.

Methods: This was a post hoc study of an international prospective multicenter study where data on patients with suspected AMI were collected.

High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S.

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihilation of dark matter particles. We present a high-statistics measurement of the spectrum of CRe candidate events from 0.3 to 40 TeV with the High Energy Stereoscopic System, covering 2 orders of magnitude in energy and reaching a proton rejection power of better than 10^{4}.

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.

Loncastuximab tesirine in previously treated diffuse large B-cell lymphoma: A plain language summary of the LOTIS-2 study.

What Is This Summary About?: This article provides a plain-language summary of the results of a clinical trial called the LOTIS-2 study.The LOTIS-2 study included 145 participants with an aggressive type (one that forms, grows, or spreads quickly) of non-Hodgkin lymphoma called diffuse large B-cell lymphoma (a type of blood cancer), or DLBCL for short, whose disease came back or did not respond after 2 or more previous treatments. The LOTIS-2 study was conducted from August 2018 to September 2022.

Combining Imaging and Electrophysiology to Visualize and Record Spreading Depolarizations in Mice.

Spreading Depolarizations (SDs) are massive events in the brain that often go undetected due to their slow propagation through gray matter. Because SD detection can be elusive, it is optimally confirmed using multiple methods. This protocol describes methods for combining imaging and electrophysiology to detect SDs in a manner that most laboratories can reliably and easily adopt.
