Urolithiasis or urinary stone disease has been estimated to affect about 1 in 11 Americans. Patients with urinary stone disease commonly present to the emergency department for management of their acute pain. In addition to providing analgesia, administration of drug (medical expulsive therapy) is often prescribed to assist passage of the urinary stone. In this methodology paper, we describe the design of a prospective, multi-center, randomized, double-blind placebo controlled clinical trial of the alpha-adrenergic blocker, tamsulosin, to evaluate its effectiveness as medical expulsive therapy. In addition, we describe the unique challenges of conducting a trial of this type within the …

Extracorporeal Membrane Oxygenation With Multiple-Organ Failure: Can Molecular Adsorbent Recirculating System Therapy Improve Survival?, Bailey E. Sparks, Nicholas C. Cavarocchi, Hitoshi Hirose

BACKGROUND: Liver dialysis, molecular adsorbent recirculating system (MARS) particularly, has been used in liver failure to bridge to transplantation. We expanded the indication for MARS to patients with acute shock liver failure and cardiopulmonary failure on extracorporeal membrane oxygenation (ECMO), aiming to improve survival to wean from ECMO.
METHODS: Retrospective chart analysis of patients on ECMO between 2010 and 2015 found 28 patients who met the criteria for acute liver failure, diagnosed by hyperbilirubinemia (total bilirubin ≥10 mg/dl) or by elevated transaminase (alanine transaminase >1,000 IU/liter). Of these patients, 14 underwent MARS treatment (Group M), and 14 were supported with …

INTRODUCTION: Since the creation of Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) patient satisfaction (PS) scores, patient experience (PE) has become a metric that can profoundly affect the fiscal balance of hospital systems, reputation of entire departments and welfare of individual physicians. While government and hospital mandates demonstrate the prominence of PE as a quality measure, no such mandate exists for its education. The objective of this study was to determine the education and evaluation landscape for PE in categorical emergency medicine (EM) residencies.
METHODS: This was a prospective survey analysis of the Council of Emergency Medicine Residency …

OBJECTIVES: Subharmonic imaging (SHI) is a technique that uses the nonlinear oscillations of microbubbles when exposed to ultrasound at high pressures transmitting at the fundamental frequency ie, f
METHODS: Eight waveforms with different envelopes were optimized with respect to acoustic power at which the SHAPE study is most sensitive. The study was run with four input transmit cycles, first in vitro and then in vivo in three canines to select the waveform that achieved the best sensitivity for detecting changes in portal pressures using SHAPE. A Logiq 9 scanner with a 4C curvi-linear array was used to acquire 2.5 MHz …

Proteoglycan Neofunctions: Regulation Of Inflammation And Autophagy In Cancer Biology., Liliana Schaefer, Claudia Tredup, Maria A. Gubbiotti, Renato V. Iozzo

Inflammation and autophagy have emerged as prominent issues in the context of proteoglycan signaling. In particular, two small, leucine-rich proteoglycans, biglycan and decorin, play pivotal roles in the regulation of these vital cellular pathways and, as such, are intrinsically involved in cancer initiation and progression. In this minireview, we will address novel functions of biglycan and decorin in inflammation and autophagy, and analyze new emerging signaling events triggered by these proteoglycans, which directly or indirectly modulate these processes. We will critically discuss the dual role of proteoglycan-driven inflammation and autophagy in tumor biology, and delineate the potential mechanisms through which …

OBJECTIVE: Plasma adiponectin (APN) levels are decreased in diabetic patients. Dysfunctional mitochondrial biogenesis is involved in type 2 diabetes (T2DM) pathogenesis, by unclear mechanisms. The present study determined (1) whether myocardial mitochondrial biogenesis was impaired in cardiomyocytes exposed to a high glucose/high fat (HGHF) medium (a T2DM in vitro model), (2) the effects of APN administration upon mitochondrial biogenesis in cardiomyocytes affected by HGHF incubation, and 3) the involved underlying mechanisms.
MATERIALS AND METHODS: Neonatal rat ventricular myocytes (NRVMs) were isolated and incubated in HGHF medium. Mitochondrial function was assessed by ATP content, and fluorescent microscopic analysis of myocardial apoptosis …

INTRODUCTION: Benefits of post-simulation debriefings as an educational and feedback tool have been widely accepted for nearly a decade. Real-time, non-critical incident debriefing is similar to post-simulation debriefing; however, data on its practice in academic emergency departments (ED), is limited. Although tools such as TeamSTEPPS® (Team Strategies and Tools to Enhance Performance and Patient Safety) suggest debriefing after complicated medical situations, they do not teach debriefing skills suited to this purpose. Anecdotal evidence suggests that real-time debriefings (or non-critical incident debriefings) do in fact occur in academic EDs;, however, limited research has been performed on this subject. The objective of …
Targeting The Nrf2-Heme Oxygenase-1 Axis After Intracerebral Hemorrhage., Jing Chen-Roetling, Raymond F. Regan

BACKGROUND: Injury to cells adjacent to an intracerebral hemorrhage (ICH) is likely mediated at least in part by toxins released from the hematoma that initiate complex and interacting injury cascades. Pharmacotherapies targeting a single toxin or pathway, even if consistently effective in controlled experimental models, have a high likelihood of failure in a variable clinical setting. Nuclear factor erythroid-2 related factor 2 (Nrf2) regulates the expression of heme oxygenase-1 (HO-1) and multiple other proteins with antioxidant and antiinflammatory effects, and may be a target of interest after ICH.
METHODS: Studies that tested the effect of HO and Nrf2 in models …

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 …

Postoperative infection after elective arthrodesis of the interphalangeal joint is an uncommon complication often necessitating urgent debridement. We present the rare case of a female patient with a history of oral herpetic lesions, who underwent elective arthrodesis of the middle and index fingers for treatment of erosive osteoarthritis and subsequently developed a postoperative herpetic infection at the surgical site.
