Development Of A Standard And Functional Tactical Emergency Medical Curriculum -- Tems Medic, Benjamin Hannon

Honors Theses

Violent crime causes death and injury regularly in the United States. Some events such as the Newtown shootings, the Oklahoma City bombings, or the Washington, DC sniper case acutely focus the entire nation’s attention while other, less contemporary events fade away. The public safety apparatus – police, fire, and emergency medical services – always respond to save lives. On December 11, 2012 a man opened fire at a mall in Clackamas County, Oregon. The 9-1-1 dispatchers sent units to a shooting at the mall and then quickly reported that the shooter was still firing in the mall. One of the …

Optimizing Atraumatic Emergency Care In Child Sexual Abuse, Kristen A. Morris

Evidence-Based Practice Project Reports

Child sexual abuse has been identified as a common problem. According to the United States Department of Health and Human Services, in 2010 it was estimated that child victims of sexual abuse accounted for 9.2% (69,368) of the 573,794 children under the age of 12 years who were the victims of maltreatment. The emergency department (ED) is often the point of entry into the healthcare system for child sexual abuse victims, which adds to the resource burden of this department nationwide. The purpose of this evidence-based project was to develop a best-practice screening tool for medical providers to guide the …

ETSU Faculty Works

Introduction: The aging population is a rapidly growing demographic in the United States. Isolation, limited autonomy, and declining physical and mental health render many older adults vulnerable to elder mistreatment (EM). The purpose of this study was to assess the prevalence and correlates of EM among a sample of older adults using legal assistance services in Atlanta, Georgia.

Methods: Researchers administered surveys to consenting older adults (aged 60þ) in 5 metro Atlanta community centers that hosted legal assistance information sessions as part of the Elderly Legal Assistance Program. The surveys screened for risk factors and prevalence of EM risk using …

Aortic Dissection Presenting As Gait Disturbance: A Case Report., Michael Estreicher, Joseph Portale, Bernard Lopez

Department of Emergency Medicine Faculty Papers

Emergency medicine dogma traditionally teaches that aortic dissection presents as tearing chest pain, radiating to the back. This case report describes a 55 year old woman presenting with a left homonymous hemianopsia and resultant gait disturbance. Initial head CT demonstrated a right parietal infarct, and chest radiograph demonstrated a markedly widened mediastinum. Acute Stanford Type A aortic dissection was subsequently confirmed. This report provides further evidence for atypical, painless presentations of aortic dissection. Given recent literature on the increasing prevalence of painless dissection, the disease entity should be included in the differential diagnosis for stroke, and a simple portable chest …

Tumor Necrosis Factor-Α And Lymphotoxin-Α Mediate Myocardial Ischemic Injury Via Tnf Receptor 1, But Are Cardioprotective When Activating Tnf Receptor 2., Yanqing Zhang, Jianli Zhao, Wayne Bond Lau, Li-Yuan Jiao, Baojiang Liu, Yuexing Yuan, Xiaoliang Wang, Erhe Gao, Walter J Koch, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

OBJECTIVE: This study determines the roles of tumor necrosis factor-α (TNFα) and lymphotoxin-α (LTα) in post-myocardial infarction (post-MI) cardiac injury, and identifies the TNF receptor type responsible for TNFα- and LTα-mediated cardiac injury.

METHODS AND RESULTS: Adult male wild type (WT), TNFα(-/-), LTα(-/-), TNFR1(-/-), and TNFR2(-/-) mice were subjected to MI via coronary artery occlusion. Functional, histological, and biochemical analyses were performed 1 to 7 days post-MI. In WT mice, MI significantly increased both TNFα and LTα levels in plasma, but in distinct temporal manner. Plasma TNFα peaked 1 day after MI, and decreased toward baseline 3 days after MI. …

Rewarming For Accidental Hypothermia In An Urban Medical Center Using Extracorporeal Membrane Oxygenation., David Morley, Kentaro Yamane, Rika O'Malley, Nicholas Cavarocchi, Hitoshi Hirose

Department of Emergency Medicine Faculty Papers

BACKGROUND: Accidental hypothermia complicated by cardiac arrest carries a high mortality rate in urban areas. For moderate hypothermia cases conventional rewarming methods are usually adequate, however in severe cases extracorporeal membrane oxygenation (ECMO) is known to provide the most efficient rewarming with complete cardiopulmonary support. We report a case of severe hypothermia complicated by prolonged cardiac arrest successfully resuscitated using ECMO.

CASE REPORT: A 45 year old female was brought to our emergency department with a core body temperature

CONCLUSIONS: This case demonstrates the advantages of advanced internal rewarming techniques, such as ECMO, for quick and efficient rewarming of severely …

Ginsenoside Rd Attenuates Myocardial Ischemia/Reperfusion Injury Via Akt/Gsk-3Β Signaling And Inhibition Of The Mitochondria-Dependent Apoptotic Pathway., Yang Wang, Xu Li, Xiaoliang Wang, Wayne Bond Lau, Yajing Wang, Yuan Xing, Xing Zhang, Xinliang Ma, Feng Gao

Department of Emergency Medicine Faculty Papers

Evidence suggests Ginsenoside Rd (GSRd), a biologically active extract from the medical plant Panax Ginseng, exerts antioxidant effect, decreasing reactive oxygen species (ROS) formation. Current study determined the effect of GSRd on myocardial ischemia/reperfusion (MI/R) injury (a pathological condition where ROS production is significantly increased) and investigated the underlying mechanisms. The current study utilized an in vivo rat model of MI/R injury and an in vitro neonatal rat cardiomyocyte (NRC) model of simulated ischemia/reperfusion (SI/R) injury. Infarct size was measured by Evans blue/TTC double staining. NRC injury was determined by MTT and lactate dehydrogenase (LDH) leakage assay. ROS accumulation and …

The Tip Of The Tail Needle Affects The Rate Of Dna Delivery By Bacteriophage P22., Justin C Leavitt, Lasha Gogokhia, Eddie B Gilcrease, Anshul Bhardwaj, Gino Cingolani, Sherwood R Casjens

Department of Biochemistry and Molecular Biology Faculty Papers

The P22-like bacteriophages have short tails. Their virions bind to their polysaccharide receptors through six trimeric tailspike proteins that surround the tail tip. These short tails also have a trimeric needle protein that extends beyond the tailspikes from the center of the tail tip, in a position that suggests that it should make first contact with the host's outer membrane during the infection process. The base of the needle serves as a plug that keeps the DNA in the virion, but role of the needle during adsorption and DNA injection is not well understood. Among the P22-like phages are needle …

Evidence-Based Protocols For Assessment And Treatment Of Adolescent Suicide Risk In An Emergency Department, Rebecca Bentele

All Graduate Theses, Dissertations, and Other Capstone Projects

Suicide and suicide attempts are a frequently encountered clinical crisis and the assessment, management and treatment of suicidal patients is one of the most stressful tasks for clinicians (Fowler, 2012). The purpose of this project was to examine whether current assessment and treatment protocols followed in the ED, Mankato, adhere to best-­‐practices as identified through research, as well as to make recommendations to MCHS-­‐Mankato for future considerations and potential modifications to existing protocols.

Effect Of Blood Collection Practices On Emergency Department Blood Specimen Rejection Rates, Barbara K. Vernoski

UNF Graduate Theses and Dissertations

The practice of obtaining blood as part of the placement of a new peripheral venous access device (p-VAD) is a frequent practice in the emergency department (ED). Of the concerns related to this practice is the possibility of laboratory specimen rejection due to p-VAD catheter size, use of the wrong collection device, and the absence of a standardized collection process. The objective of this study, therefore, was to examine the effect of the use of evidence-based venipuncture and p-VAD blood collection protocols on the rejection rate of blood specimens drawn by staff in the adult areas of an urban academic …

Current Opinion On Nanotoxicology, Ali Pourmand, Mohammad Abdollahi

Emergency Medicine Faculty Publications

Nanotechnology is one of the premiere technologies available today, having expanded both as field of scientific study and in the public consciousness. Despite this growth, the drawbacks, limitations and potential safety hazards associated with the incorporation of nanotechnology into existing industries are still being learned. The noticeable point is that there is no enough data available yet to analyze global use of nanotechnology from a meta-perspective. Three challenges can be defined in light of nanotoxicology. One, materials that might prove to be significantly toxic must be identified. Two, a system for the categorization of NP materials must be codified and …

Effect Of Iron Chelators On Methemoglobin And Thrombin Preconditioning., Jing Chen-Roetling, Jesse Sinanan, Raymond F. Regan

Department of Emergency Medicine Faculty Papers

Cell loss immediately adjacent to an intracerebral hemorrhage may be mediated in part by the toxicities of extracellular hemoglobin (Hb) and thrombin. However, at low concentrations, these proteins induce tolerance to hemin and iron that may limit further peri-hematomal injury as erythrocyte lysis progresses. The mechanisms mediating these preconditioning effects have not been completely defined, but increased expression of both heme oxygenase (HO)-1 and iron binding proteins likely contributes. In the present study, we hypothesized that iron chelator therapy would attenuate this protective response. Pretreatment of cortical glial cultures (> 90 % GFAP+) with 3 μM methemoglobin (metHb) or 5 …

Decrease In Central Venous Catheter Placement And Complications Due To Utilization Of Ultrasound-Guided Peripheral Intravenous Catheters, Arthur K Au, Masashi Rotte, Robert Grzybowski, Bon Ku, Jason M. Fields

Department of Emergency Medicine Faculty Papers

Poster presented at: American College of Emergency Physicians (ACEP) conference.

Introduction: -Up to 40% of ED visits include diagnostic blood tests and 26% result in administration of IV fluids necessitating successful peripheral intravenous (IV) catheter placement.1 -There is a subset of patients with difficult IV access (DIVA) in which traditional cannulation methods are unsuccessful resulting in central venous cannulation (CVC). -CVCs have a 5-15 percent complication rate2 and attributable costs per CVC related infection have been estimated at $34,508-$56,000.3 -Ultrasound-guided peripheral IV catheters (USGPIVs) provide a method of potentially decreasing the need for CVC placement, however due to poor durability …

Perspective On Lead Toxicity: A Comparison Between The United States And Iran, Ali Pourmand, Tareq Khedir Al-Tiae, Maryann Mazer-Amirshahi

Emergency Medicine Faculty Publications

Lead is a pervasive toxin that has been implicated in human poisonings throughout history. Exposure mitigation strategies in the United States and worldwide have led to a decline in symptomatic poisonings and population blood lead levels; however, lead remains a major health hazard. In this article, we review the history of lead toxicity, clinical manifestations ranging from subclinical and subtle features to life-threatening complications, and the subsequent public health interventions in the US. In addition, we explore common routes of lead exposure and the unique differences between the US and Iran. Although the US has made significant strides with regard …
