Serious outcomes among emergency department patients with presyncope: A systematic review

Academic Emergency Medicine, EarlyView.
Abstract Background Syncope is transient loss of consciousness, and in presyncope, patients experience same prodromal symptoms without losing consciousness. While studies have extensively reported the risk of serious outcome among emergency department (ED) syncope, the outcome for patients with presyncope and their management are not well studied.

Clinically Significant Neuroimaging Findings Among Pediatric Patients Presenting to the Emergency Department With Symptoms of Psychosis: A Multicenter Retrospective Study

Academic Emergency Medicine, EarlyView.
ABSTRACT Background The clinical utility of diagnostic neuroimaging for pediatric patients presenting to the emergency department (ED) for psychosis remains unclear. We sought to estimate the prevalence of and characteristics associated with clinically significant neuroimaging findings among pediatric patients presenting to the ED with symptoms of ...

Pre‐operative anaemia, red blood cell transfusion and mortality after cardiac surgery: a Netherlands Heart Registration mediation analysis

Anaesthesia, EarlyView.
Summary Introduction Pre‐operative anaemia is an established risk factor for mortality after cardiac surgery. The extent to which this risk is mediated by complications related to red blood cell transfusion remains uncertain, particularly across different age groups.

Machine Learning‐Based Prediction of Life‐Threatening Complications During Hemodialysis in Hospitalized Patients With Poor General Conditions

Artificial Organs, EarlyView.
A machine learning model using predialysis data predicted sudden events during or after hemodialysis with high accuracy (auROC: 0.889). The key predictors included emergency hospitalization, recent surgery, high heart rate, low albumin levels, and high CRP.

Preoperative Atrial Fibrillation Does Not Impact Long‐Term Survival and Complications in Left Ventricular Assistance Device Recipients

Artificial Organs, EarlyView.
In this large multicenter study, AF before LVAD implantation was not associated with increased risks of mortality, bleeding, stroke, or pump thrombosis, but was linked to a higher incidence of late VAs. ABSTRACT Introduction A substantial proportion of patients receiving left ventricular assist devices (LVADs) present with pre‐existing atrial ...
