Randomized Controlled Trial Multicenter Study Comparative Study
A comparative study of dexmedetomidine and propofol to prevent recovery agitation in adults undergoing procedural sedation with ketamine: A randomized double-blind clinical trial.
The present study was designed to evaluate the effect of dexmedetomidine and propofol on ketamine-induced recovery agitation in adults when used as co-administration with ketamine. ⋯ In this study, a combination of ketamine-dexmedetomidine and ketamine-propofol reduced the incidence and severity of ketamine-induced recovery agitation in adults undergoing procedural sedation in the ED.

Multicenter Study
Clinical prediction rule of termination of resuscitation for out-of-hospital cardiac arrest patient with pre-hospital defibrillation given.
To derive a clinical prediction rule of termination of resuscitation (TOR) for out-of-hospital cardiac arrest (OHCA) with pre-hospital defibrillation given. ⋯ The 2-criteria TOR rule for OHCA patients with pre-hospital defibrillation had a high specificity and PPV for predicting death on or before ED arrival.

Multicenter Study Observational Study
Can plain film radiography improve the emergency department detection of clinically important urinary stones?
Physicians frequently use ultrasound to assess hydronephrosis in patients with suspected renal colic, but ultrasound has limited diagnostic sensitivity and rarely clarifies stone size or location. Consequently, up to 80% of emergency department (ED) renal colic patients undergo confirmatory CT imaging. Our goal was to estimate x-ray sensitivity for urinary stones and determine whether x-ray substantially improves stone detection (sensitivity) compared to hydronephrosis assessment alone. ⋯ Adding x-ray to hydronephrosis assessment substantially improves diagnostic sensitivity, enabling the detection of nearly 70% of large stones and over 80% of interventional stones. This level of sensitivity may be sufficient to reassure physicians about a renal colic diagnosis without CT imaging for many patients.

Multicenter Study
The impact of antihypertensive use in the treatment of acute ischemic stroke in patients receiving alteplase.
Treatment of acute ischemic stroke (AIS) with intravenous alteplase within 4.5 h of symptom onset is associated with neurologic improvement. High baseline blood pressure (BP) and BP variability during the first 24 h of AIS is associated with increased early adverse events and death. The purpose of this study is to characterize the incidence of poor neurologic outcome in patients treated with alteplase for AIS who received antihypertensive medications prior to and within the first 24 h following alteplase administration compared with patients who did not. ⋯ Antihypertensive treatment in the first 24 h of AIS was associated with poor neurologic outcomes at 90 days. However, after controlling for other clinical factors in a multivariable logistic regression, this association was no longer observed.

The use of accurate prediction tools and early intervention are important for addressing severe coronavirus disease 2019 (COVID-19). However, the prediction models for severe COVID-19 available to date are subject to various biases. This study aimed to construct a nomogram to provide accurate, personalized predictions of the risk of severe COVID-19. ⋯ The nomogram was a reliable tool for assessing the probability of severe COVID-19 and may facilitate clinicians stratifying patients and providing early and optimal therapies.
