Randomized Controlled Trial Comparative Study
Evaluation of gum-elastic bougie combined with direct and indirect laryngoscopes in vomitus setting: A randomized simulation trial.
Videolaryngoscopes may not be useful in the presence of vomitus due to blurred images on the monitor. The objective of our study is to compare the utility of gum-elastic bougie (GEB) application for tracheal intubation with the Macintosh laryngoscope (McL), which is a direct laryngoscope, with that of the Pentax-AWS Airwayscope® (AWS) and McGRATH® MAC (McGRATH) in simulated vomitus settings. ⋯ The GEB application facilitates the tracheal intubation in the vomitus setting using McGRATH and AWS in adult simulation.

To assess and compare the diagnostic value of lactate, procalcitonin (PCT) and C-reactive protein (CRP) in low, moderate, and high-risk stratified population applying Mortality in Emergency Department (MEDS) risk score using Bayesian statistical modeling. ⋯ Bayesian statistical model demonstrated the superior diagnostic quality of PCT. For ruling out severe disease, lactate yielded a higher benefit with increased relative gain with negative LR.

Observational Study
Development and validation of clinical risk score to predict the cardiac rupture in patients with ST-elevation myocardial infarction.
Cardiac rupture (CR) is a fatal complication of ST-elevation myocardial infarction (STEMI) with poor prognosis. The aim of this study was to develop and validate practical risk score to predict the CR after STEMI. ⋯ A simple risk score system based on 7 baseline clinical variables could identify patients with high risk of CR, for whom appropriate treatment strategies can be implemented.
