Multicenter Study
Association of recent major psychological stress with cardiac arrest: A case-control study.
We hypothesized that major psychological stress can be a risk factor for cardiac arrest and that effects are modified by elapsed time from specific stressful events. ⋯ MLEs were associated with cardiac arrest occurrence, and the effect was modified by the elapsed time from the MLEs.

This study aimed to clarify the association between the crowding and clinical practice in the emergency department (ED). ⋯ Overcrowding in the ED might increase physicians' decision-making time and patients' length of stay, and more patients could be admitted to observation units or an inpatient department. The use of CT and laboratory examinations would also increase. All of these could lead more patients to stay in the ED.

This study aimed to determine which children with suspected appendicitis should be considered for a computerized tomography (CT) scan after a non-diagnostic ultrasound (US) in the Emergency Department (ED). ⋯ Ordering CT should be considered after non-diagnostic US for appendicitis only when children meet at least 2 predictors of RLQ tenderness, peritoneal signs and WBC>10,000 in mm3.

Comparative Study
Effect of the Macintosh curved blade size on direct laryngoscopic view in edentulous patients.
In the present study, we compared the laryngoscopic view depending on the size of the Macintosh curved blade in edentulous patients. ⋯ Compared to a standard-sized Macintosh blade, a smaller-sized Macintosh curved blade improved the laryngeal exposure in edentulous patients.

Comparative Study
Psychological scales as predictors of emergency department hospitalizations in suicide attempters.
The purpose of this study was to evaluate the psychological scales reflecting lethality and intent as predictors of suicide attempter's hospitalization. ⋯ The psychological scales can be helpful for predicting suicide attempter's hospitalization in emergency settings. Especially, the RRRS seemed to have a superior predictive ability. Moreover, combining the scales had significantly better predictive performance than use of the individual scale alone did.
