Exploring Standardized Patients’ Perspectives On Working With Medical Students, Samantha Starr, Margaret M. Plack, Karen Lewis, Benjamin Blatt

GW Research Days 2016 - 2020

Little is known about how working with emerging medical professionals affects Standardized Patients’ (SPs’) professional identities, yet understanding the SP-medical student interaction could be useful for screening SPs, supporting SP professional identity formation, and bridging the SP and medical student cultures. This project provides the unique perspective of SPs involved in the growth of medical students into physicians.

Qualitative methods were used to understand the SPs’ perspectives. Two researchers, without evaluative relationships with the SPs, conducted 2 one-hour focus group interviews (n=3; n=9) using a semi-structured interview protocol. Interviews were audio-recorded and transcribed verbatim. Three researchers independently analyzed the transcripts …

Piloting Carestart™ Rapid Diagnostic Test (Rdt) To Promote Glucose-6-Phosphate Dehydrogenase (G6pd) Screening In Malaria Endemic Community In Cambodia, Bertha Nyagaya-Wojnarski, +Several Additional Authors

GW Research Days 2016 - 2020

Background: Primaquine (PQ) is the only FDA-approved drug for radical cure of Plasmodium vivax (P.v) malaria, but treatment can result in life-threatening hemolysis if given to a glucose-6-phosphate dehydrogenase deficient (G6PDd) patient. Therefore, the G6PD status of the patient with P.v must be known prior to prescribing PQ. However, a patient’s G6PD status in rural malaria endemic settings is generally unknown, illuminating the need for reliable point of care G6PD diagnostic tests as a prerequisite to safely administer PQ. To increase community PQ access in Cambodia, performance of CareStart™ G6PD rapid diagnostic tests (RDTs) needs to …

Occupational Exposure To Solvents And Associated Neurotoxicity In Construction Painters: A Systematic Review, Allison Cailliau

GW Research Days 2016 - 2020

Background

Existing evidence suggests that occupational exposure to solvents can have devastating and adverse effects on cognitive function. Individuals in the construction industry, specifically construction painters, often come in contact with these harmful chemicals on a regular basis. A solvent is a liquid that can dissolve, suspend, or extract other materials without chemical change to the solvent itself. They are present in a wide range of industries and can be used for extraction of fats and oils, degreasing, or manufacturing of paints and plastics. Their main routes of exposure are through inhalation and skin absorption, and they have a tendency …

An Assessment Of Cultural Perceptions And Recognition Of Ebola Virus Disease, And Its Correlation With Traditional Burial Practice In Rural Guinea, Chulwoo Park, Amira Roess, Sally Lahm, Mamadou Kally Bah, Mohamed Campel Camara, John Sandberg

GW Research Days 2016 - 2020

Background:

In the midst of the unprecedented Ebola outbreak in West Africa during 2014-2016, the humanitarian response to control the disease was hampered in part because there was a limited understanding of local traditional rituals or indigenous medicine (ethnomedicine) on the part of the responders. The Ebola outbreak claimed 11,310 lives, more than all other outbreaks combined. West African burial funeral ceremonies and surrounding rituals may have hindered interventions that included the forceful removal of the sick or dead from the community.

Objective:

Our objective was to understand transmission associated with traditional burial practices in rural Guinea. Through the lens …

Pupillometric Assessment Of Small Doses Of Opioid In A Pediatric Population, David Strum, Elizabeth Malphrus, Kevin Jackson, Julia Finkel

GW Research Days 2016 - 2020

According to the CDC, opioid prescriptions in the United States have more than tripled from 1999-2014, which has correlated with the staggering increase in opioid-involved drug overdose deaths. This pattern of prescription is thought to be a major contributory factor to the increase in drug overdose in America, as four out of five new heroin users started by misusing prescription painkillers. Providers need the means to objectively monitor analgesic efficacy of treatment in patients with pain to mitigate unnecessary analgesic prescribing.

It is well established that mu opioid agonists like morphine cause miosis, an effect to which tolerance does not …

Al-Amoodi, Whitney Jones, Danny Lee, Steven Mckenzie, Helen C. Miller, Zach Zeller, Seth Stubblefield, Susan Knoblach, Heather Gordish-Dressman, Dustin Hittel, Laura L. Tosi

GW Research Days 2016 - 2020

INTRODUCTION: Osteoporosis is a significant burden for our aging population. Developing a better understanding of the genetic underpinnings of poor bone quality may assist in the future development of prevention strategies. Correa-Rodriguez et al. have identified a group of single nucleotide polymorphisms (SNPs) that were associated with bone mineral density (BMD) in a population of Spanish Caucasians. In particular, they found that SNP rs3736228 in the low-density lipoprotein receptor related protein 5 (LRP5) gene had an influence on BMD. While the role of LRP5 in the Wnt canonical pathway has been fairly well characterized, its association with phenotypic BMD and …

Acute Hepatic Failure And Oral Amiodarone, Hani Alhamoud, Sivateja Mandava, Talal Alzahrani

GW Research Days 2016 - 2020

Introduction:

Amiodarone is associated with serious complications such as lung toxicity, thyroid dysfunction, and QT-prolongation. Further, hepatic failure from the intravenous (IV) formulation of amiodarone is described in numerous case reports and case series. Although there are reports of elevated liver enzymes from the oral formulation of amiodarone, to our knowledge, none have definitively identified a case of acute hepatic failure from the oral formulation alone. In this case, we report an instance of acute hepatic failure after increasing the oral amiodarone dosage as well as rapid recovery following cessation of the medication.

Case report:

Lumbar Decompression Surgery: Does Chronic Steroid Use Increase The Risk Of Postoperative Infectious Complications? – A Study Of The National Surgical Quality Improvement Program (Nsqip) Database, Shane Sobrio, Mikel Thista, Raj Rao, Alex Gu, Chapman Wei, Warren Yu

GW Research Days 2016 - 2020

Intro: It has long been established that corticosteroids have a negative impact on the human immune system’s ability to function at an optimal level. Many past studies have shown that patient’s will have higher rates of infection if they are taking chronic steroids. What has yet to be established is just how much of an increased risk patients on chronic steroids have for infection after undergoing lumbar decompression surgeries, of which there are thousands per year. We hypothesize that patients on chronic steroids will have higher rates of surgical site infections and higher rates of other infections (UTI, pneumonia, etc.) …

Tumor Surveillance Using Liquid Biome In Pediatric High Grade Gliomas, Erin Bonner, Eshini Panditharatna, Madhuri Kambhampati, Stefaan Van Gool, Wilfried Stuecker, Roger J. Packer, Javad Nazarian

GW Research Days 2016 - 2020

Immunotherapy is currently being used to treat pediatric brain cancer, though its efficacy in treating patients with diffuse intrinsic pontine glioma (DIPG), the deadliest pediatric brain tumor, has not been evaluated. MRI is the gold standard for monitoring tumor response to therapy, but is limited by pseudoresponse and psuedoprogression: post-treatment, immune cells infiltrate the primary tumor causing transient tumor enlargement, which falsely resembles tumor progression on MRI. Thus, it is critical to develop more accurate approaches to monitor tumor response to immunotherapy. Here, we use a liquid biopsy platform we have already established to monitor tumor response to therapy, to …

GW Research Days 2016 - 2020

Background

Between 2012 and 2016, the opioid overdose mortality rate in the U.S. almost doubled from 7.4 to 13.3 per 100,000 population, leading to calls for a national opioid crisis. This crisis has generated interest in Medicaid’s dual role as a health insurance system that provides reimbursement for both prescription opioid analgesics like Oxycodone used to treat chronic pain, which could inadvertently fuel addiction, and prescription opioids used as treatment medication to help people survive and recover from drug abuse, such as Naloxone.

Methods

In this study, we conduct a multi-variate analysis of Medicaid prescription drug utilization data for the …
