Evaluation of Gender Differences in Ultrasound Milestone Evaluations During Emergency Medicine Residency Training: A Multicenter Study.

Objectives: Prior literature has demonstrated incongruities among faculty evaluation of male and female residents' procedural competency during residency training. There are no known studies investigating gender differences in the assessment of procedural skills among emergency medicine (EM) residents, such as those required by ultrasound. The objective of this study was to determine if there are significant gender differences in ultrasound milestone evaluations during EM residency training.

Serial sodium values and adverse outcomes in heart failure with preserved ejection fraction.

Objective: The purpose of our study is to examine whether serial measurements of serum sodium values after diagnosis identify a higher-risk subset of patients with heart failure with preserved ejection fraction.

Methods: We identified 50,932 subjects with HFpEF with 759,577 recorded sNa measurements (mean age 72 ± 11 years) using a validated algorithm in the VA national database from 2002 to 2012. We examined the association of repeated measures of sNa with mortality using a multivariable Cox proportional hazards model.

Ambulances under siege in Syria.

Background: Healthcare is under attack in Syria with repeated air strikes on hospitals and ambulances and the largest death toll of health workers in any recorded conflict.1 Ambulances in Syria have been bombed, shot at, stolen, looted and obstructed, significantly impeding their ability to safely evacuate the wounded and provide medical aid.

Methods: This article presents the summary of a literature review on attacks against ambulances in Syria from 2011 to 2018, as well as a descriptive secondary data analysis on individual attacks reported by the Syrian Network for Human Rights from January 2016 to December 2017.

Development and validation of a heart failure with preserved ejection fraction cohort using electronic medical records.

Background: Heart failure (HF) with preserved ejection fraction (HFpEF) comprises nearly half of prevalent HF, yet is challenging to curate in a large database of electronic medical records (EMR) since it requires both accurate HF diagnosis and left ventricular ejection fraction (EF) values to be consistently ≥50%.

Methods: We used the national Veterans Affairs EMR to curate a cohort of HFpEF patients from 2002 to 2014. EF values were extracted from clinical documents utilizing natural language processing and an iterative approach was used to refine the algorithm for verification of clinical HFpEF.

Prognostic Significance of Baseline Serum Sodium in Heart Failure With Preserved Ejection Fraction.

Background: The purpose of this study was to evaluate the relationship between serum sodium at the time of diagnosis and long term clinical outcomes in a large national cohort of patients with heart failure with preserved ejection fraction.

Methods And Results: We studied 25 440 patients with heart failure with preserved ejection fraction treated at Veterans Affairs medical centers across the United States between 2002 and 2012. Serum sodium at the time of heart failure diagnosis was analyzed as a continuous variable and in categories as follows: low (115.

Angiotensin-Converting Enzyme Inhibitors in Hypertension: To Use or Not to Use?

Most guidelines for the management of patients with cardiovascular disease recommend angiotensin-converting enzyme (ACE) inhibitors as first-choice therapy, whereas angiotensin receptor blockers (ARBs) are merely considered an alternative for ACE inhibitor-intolerant patients. The aim of this review was to compare outcomes and adverse events between ACE inhibitors and ARBs in patients. In patients with hypertension and hypertension with compelling indications, we found no difference in efficacy between ARBs and ACE inhibitors with regard to the surrogate endpoint of blood pressure and outcomes of all-cause mortality, cardiovascular mortality, myocardial infarction, heart failure, stroke, and end-stage renal disease.

A novel method for creating custom shaped ballistic gelatin trainers using plaster molds.

Simulation based procedural training is an effective and frequently used method for teaching vascular access techniques which often require commercial trainers. These can be prohibitively expensive, which allows for homemade trainers made of gelatin to be a more cost-effective and attractive option. Previously described trainers are often rectangular with a flat surface that is dissimilar to human anatomy.

Duration of Dual Antiplatelet Therapy in Patients with an Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention.

Background: The recent American Heart Association/American College of Cardiology guidelines on duration of dual antiplatelet therapy (DAPT) recommend DAPT for 1 year in patients presenting with an acute coronary syndrome, with a Class IIb recommendation for continuation. We aim to assess the evidence for these recommendations using a meta-analytic approach.

Methods: We searched electronic databases for randomized trials comparing short-term (≤6 months) vs 12-month vs extended (>12 months) DAPT in patients with an acute coronary syndrome undergoing percutaneous coronary intervention.

Utility of Ultrasound Guidance for Central Venous Access in Children.

Background: Placement of a central venous catheter (CVC) in a pediatric patient is an important skill for pediatric emergency medicine physicians but can be challenging and time consuming. Ultrasound (US) guidance has been shown to improve success of central line placement in adult patients.

Objectives: This article aims to review the literature and evaluate the benefit of US guidance in the placement of CVCs, specifically in pediatric emergency department patients, and to review the procedure.

Intravascular ultrasound-guided vs angiography-guided drug-eluting stent implantation in complex coronary lesions: Meta-analysis of randomized trials.

Unlabelled: The relative outcomes of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI with drug-eluting stent (DES) in complex lesions have not been established. We sought to compare the efficacy and safety of IVUS-guided PCI with angiography-guided PCI in patients with complex coronary lesions treated with DES.

Methods: Electronic databases were searched to identify all randomized trials comparing IVUS-guided vs angiography-guided DES implantation.

Ultrasound-guided dorsal penile nerve block performed in a case of zipper entrapment injury.

Injury to the penis resulting from zipper entrapment is a painful condition that presents a unique anesthetic challenge to the emergency physician and may even require procedural sedation for removal. In this case report, we describe successful removal of zipper entrapment from the penis of a 34-year-old patient after the application of an ultrasound-guided dorsal penile nerve block. We discuss the anatomy, sonographic features, and steps required for the nerve block procedure.

Outcomes of Intensive Blood Pressure Lowering in Older Hypertensive Patients.

Background: The 2014 Eighth Joint National Committee panel recommended a therapeutic target of systolic blood pressure (BP) <150 mm Hg in patients ≥60 years of age, a departure from prior recommendation of <140 mm Hg.

Objectives: This study assessed the efficacy and safety of intensive BP-lowering strategies in older (age ≥65 years) hypertensive patients.

Methods: The MEDLINE, Scopus, EMBASE, and Cochrane databases were searched for all relevant randomized controlled trials from 1965 through July 1, 2016.

Renin Angiotensin Aldosterone System Inhibitors in Hypertension: Is There Evidence for Benefit Independent of Blood Pressure Reduction?

The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in the pathogenesis of hypertension (HTN). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are first line anti-HTN drug classes that are potent, effective and largely safe. Direct renin inhibitors (DRIs) have shown similar blood pressure (BP) reduction but more side effects.

Meta-Analysis of Randomized Trials on the Efficacy and Safety of Angiotensin-Converting Enzyme Inhibitors in Patients ≥65 Years of Age.

The comparative efficacy and safety of angiotensin-converting enzyme inhibitors (ACEIs) with other agents in patients ≥65 years of age with cardiovascular diseases or at-risk are unknown. Electronic databases were systematically searched to identify all randomized controlled trials that compared ACEIs with control (placebo or active) and reported long-term cardiovascular outcomes. We required the mean age of patients in the studies to be ≥65 years.

Social Capital and the Paradox of Poor but Healthy Groups in the United States.
