BACKGROUND/AIMS: Obstructive sleep apnea hypoxia syndrome (OSAHS) is an independent risk factor for coronary artery disease (CAD). Treatment of OSAHS improves clinical outcome in some CAD patients, but the relationship between OSAHS and CAD is complex. Microparticles (MPs) are shed by the plasma membrane by either physiologic or pathologic stimulation. In the current study, we investigated the role of MPs in the context of OSAHS.

METHODS AND RESULTS: 54 patients with both suspected coronary artery stenosis and OSAHS were recruited and underwent both coronary arteriography and polysomnography. Circulating MPs were isolated and analyzed by flow cytometry. CAD+OSAHS patients exhibited greater …

Pain Perception In Latino Vs. Caucasian And Male Vs. Female Patients: Is There Really A Difference?, Molly Aufiero, Holly Stankewicz, Shaila Quazi, Jeanne Jacoby, Jill Stoltzfus

Aria Health Papers

INTRODUCTION: Pain is a common emergency department (ED) complaint. It is important to understand the differences in pain perception among different ethnic and demographic populations.

METHODS: We applied a standardized painful stimulus to Caucasian and Latino adult patients to determine whether the level of pain reported differed depending on ethnicity (N=100; 50 Caucasian [C], 50 Latino [L] patients) and gender (N=100; 59 female, 41 male). Patients had an initial pain score of 0 or 1. A blood pressure cuff was inflated 20 mm HG above the patient's systolic blood pressure and held for three minutes. Pain scores, using both a …

Clinician-Performed Bedside Ultrasound In Improving Diagnostic Accuracy In Patients Presenting To The Ed With Acute Dyspnea., Dimitrios Papanagnou, Michael Secko, John Gullett, Michael Stone, Shahriar Zehtabchi

INTRODUCTION: Diagnosing acute dyspnea is a critical action performed by emergency physicians (EP). It has been shown that ultrasound (US) can be incorporated into the work-up of the dyspneic patient; but there is little data demonstrating its effect on decision-making. We sought to examine the impact of a bedside, clinician-performed cardiopulmonary US protocol on the clinical impression of EPs evaluating dyspneic patients, and to measure the change in physician confidence with the leading diagnosis before and after US.

METHODS: We conducted a prospective observational study of EPs treating adult patients with undifferentiated dyspnea in an urban academic center, excluding those …

Does Mental Status Impact Therapist And Patient Communication In Emergency Department Brief Interventions Addressing Alcohol Use?, Brian Borsari, Timothy R. Apodaca, Ali Yurasek, Peter M. Monti

Manuscripts, Articles, Book Chapters and Other Papers

Motivational interviewing (MI) is often incorporated into screening, brief intervention, and referral to treatment (SBIRT) interventions in critical care settings to address alcohol and other drug use. However, cognitive status has been linked to differential response to MI sessions in emergency department (ED) settings. The current study examined one possible explanation for this differential response: whether higher versus lower mental status impacts patient response to clinician statements during MI sessions conducted in an ED. Participants were 126 patients receiving an MI-based single-session alcohol brief intervention, and 13 therapists who provided treatment. Participants completed a mental status exam (MSE) as part …

Factors Associated With Post-Arrest Withdrawal Of Life-Sustaining Therapy., Anne V. Grossestreuer, David F. Gaieski, Benjamin S. Abella, Douglas J. Wiebe, Ari Moskowitz, Daniel J. Ikeda, Jason S. Haukoos, Sarah M. Perman

INTRODUCTION: Most successfully resuscitated cardiac arrest patients do not survive to hospital discharge. Many have withdrawal of life sustaining therapy (WLST) as a result of the perception of poor neurologic prognosis. The characteristics of these patients and differences in their post-arrest care are largely unknown.

METHODS: Utilizing the Penn Alliance for Therapeutic Hypothermia Registry, we identified a cohort of 1311 post-arrest patients from 26 hospitals from 2010 to 2014 who remained comatose after return of spontaneous circulation. We stratified patients by whether they had WLST post-arrest and analyzed demographic, arrest, and post-arrest variables.

RESULTS: In our cohort, 565 (43%) patients …
