Experience with Aposematic Defense Triggers Attack Bias in a Mantid Predator ().

Studies of predator psychology in aposematism have suggested important effects of signal detection through space and time on outcomes of attack behavior. Both the integration of aposematic signals from prey and experience state of the predator can have important effects on attack decisions. The universality of these effects however, especially as it applies to non-avian predators such as arthropods, remains poorly understood.

Association between intraoperative hypotension and postoperative nausea and vomiting: a retrospective cohort study.

Objective: Postoperative nausea and vomiting (PONV) occurs in up to 30% of patients and its pathophysiology and mechanisms have not been completely described. Hypotension and a decrease in cardiac output are suspected to induce nausea. The hypothesis that intraoperative hypotension might influence the incidence of PONV was investigated.

Intraoperative Hypotension Is an Important Modifiable Risk Factor for Major Complications in Spinal Fusion Surgery.

Study Design: Retrospective observational cohort.

Objectives: This study explores the impact of Intraoperative hypotension (IOH) on postoperative complications for major thoracolumbar spine fusion procedures.

Summary Of Background Data: IOH with mean arterial pressure (MAP) <65 mm Hg is associated with postoperative acute kidney injury (AKI) in general surgery.

Quality assurance of late gadolinium enhancement cardiac magnetic resonance images: a deep learning classifier for confidence in the presence or absence of abnormality with potential to prompt real-time image optimization.

Background: Late gadolinium enhancement (LGE) of the myocardium has significant diagnostic and prognostic implications, with even small areas of enhancement being important. Distinguishing between definitely normal and definitely abnormal LGE images is usually straightforward, but diagnostic uncertainty arises when reporters are not sure whether the observed LGE is genuine or not. This uncertainty might be resolved by repetition (to remove artifact) or further acquisition of intersecting images, but this must take place before the scan finishes.
