Identifying the likelihood of a patient having coronary artery disease (CAD) at the time of emergency department (ED) presentation with chest pain could reduce the need for stress testing or coronary imaging after myocardial infarction (MI) has been excluded. The authors aimed to determine if a novel cardiac biomarker consisting of plasma cholesteryl ester (CE) levels typically derived from the activity of the enzyme acyl-CoA:cholesterol acyltransferase (ACAT2) are predictive of CAD in a clinical model. ⋯ Plasma levels of ACAT2-CE have strong potential to predict a patient's likelihood of having CAD when considered in a clinical model but not when used alone. In turn, a clinical model containing ACAT2-CE could reduce the need for cardiac imaging after the exclusion of MI.

Randomized Controlled Trial Comparative Study
Randomized trial comparing intraoral ultrasound to landmark-based needle aspiration in patients with suspected peritonsillar abscess.
Traditionally, emergency physicians (EPs) have used anatomic landmark-based needle aspiration to drain peritonsillar abscesses (PTAs). If this failed, an imaging study and/or consultation with another service to perform the drainage is obtained. Recently, some EPs have used ultrasound (US) to guide PTA drainage. This study seeks to determine which initial approach leads to greater successful drainage. The primary objective of this study was to compare the diagnostic accuracy of EPs for detecting PTA or peritonsillar cellulitis (PTC) using either intraoral US or initial needle aspiration after visual inspection (the landmark technique [LM]). Secondary objectives included the successful aspiration of purulent material in those patients with a PTA in each arm, the use of computed tomography (CT) scanning in each arm, and the otolaryngology (ENT) consultation rate in each arm. ⋯ An initial intraoral US performed by EPs can reliably diagnose PTC and PTA. Additionally, using intraoral US to assist in the drainage of PTAs with needle aspiration leads to greater success compared to the traditional method of LM relying on physical exam alone.

There is increasing research interest in the risk stratification of emergency department (ED) syncope patients. A major barrier to comparing and synthesizing existing research is wide variation in the conduct and reporting of studies. The authors wanted to create standardized reporting guidelines for ED syncope risk-stratification research using an expert consensus process. ⋯ After two survey rounds, the final reporting guidelines included 92 items that achieved >80% consensus. These included 10 items for study eligibility, 23 items for outcomes, nine items for ECG abnormalities, and 50 items for candidate predictors. Adherence to these guidelines should facilitate comparison of future research in this area.

Multicenter Study
Risk factors for increased ED utilization in a multinational cohort of children with sickle cell disease.
The objective was to identify clinical, social, and environmental risk factors for increased emergency department (ED) use in children with sickle cell disease (SCD). ⋯ Asthma and exposure to environmental tobacco smoke are potentially modifiable risk factors for greater ED use in children with SCD. Low income is associated with greater ED use for SCD pain in countries with and without universal health care.

Due to antimicrobial resistance in Streptococcus pneumoniae, national guidelines recommend a respiratory fluoroquinolone or combination antimicrobial therapy for outpatient treatment of community-acquired pneumonia (CAP) associated with risk factors for drug-resistant S. pneumoniae (DRSP). The objectives of this study were to assess the prevalence of these risk factors and antibiotic prescribing practices in cases of outpatient CAP treated in the acute care setting. ⋯ DRSP risk factors were present in approximately half of outpatient CAP cases treated in the acute care setting; however, guideline-concordant antibiotic therapy was infrequent. Strict adherence to current guidelines would substantially increase use of fluoroquinolones or combination therapy. Whether the potential risks associated with these broad-spectrum regimens are justified by improved clinical outcomes requires further study.
