Measuring The Effects Of Thc On Human Sperm Parameters Using Biomonitoring Analysis, Roxana Amaya-Fuentes, Heather Young, Courtney Irwin, Jonathan Crites, David Moody, Melissa Perry

GW Research Days 2016 - 2020

Marijuana is one of the most common substances used in the United States with more men utilizing marijuana compared to women. The effects of marijuana on the brain are well known, however, there is limited research on its effects on human sperm parameters. We examined the association between THC and human sperm parameters in participants in the Washington D.C. area. Our preliminary results suggested that THC was associated with low sperm morphology.

Background: Marijuana has a long history of human usage for medicinal, ceremonial, and religious purposes. As of January 2018, nine states including Washington D.C. have legalized it for …

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 …

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:

A 61-year-old male with a …

Onyx Use In Extracranial Pathologies - A Retrospective Case Review, Faezeh Razjouyan, Rishi Sood, Alex Cho, Anthony Venbrux, Shawn Sarin

GW Research Days 2016 - 2020

Purpose:

Onyx is an embolic agent currently FDA approved for neurointerventional procedures such as in the treatment of aneurysms and arteriovenous malformations. Despite its limited indications, the agent's off-label use in the treatment of extracranial pathologies continues to increase. To date, there has not been a single-center study demonstrating a large number of cases demonstrating safe and effective peripheral embolization with Onyx.

Materials:

We performed a retrospective review of all cases that used Onyx between October 2010 and July 2016 at a single tertiary care academic university urban hospital. Institutional review board approval was appropriately obtained. Initial case selection was …

Cost-Effectiveness Of Alternative Anticoagulation Strategies For Postoperative Management Of Total Knee Arthroplasty Patients, Savannah R. Smith, Jeffrey Katz, Elena Losina

GW Research Days 2016 - 2020

Background: Anticoagulation is essential for deep vein thrombosis (DVT) and pulmonary embolism (PE) prevention following total knee arthroplasty (TKA). Some research has suggested that longer duration anticoagulation can substantially reduce the risks of DVT and PE; however, in the absence of definitive recommendations, physicians are left weighing the risks of DVT and PE against those of anticoagulation, including gastrointestinal (GI) and central nervous system (CNS) hemorrhage and increased likelihood of prosthetic joint infection (PJI). We conducted a cost-effectiveness analysis to evaluate the benefits and risks of 14- and 35-day therapy with the most commonly prescribed anticoagulants post-TKA.

Background: Anticoagulation is …

Is Androgen Excess Masked In Alopecia Areata Patients: A Retrospective Data Analysis Of 1,587 Patients, G. Cheyana Ranasinghe, Melissa Piliang, Wilma Bergfeld

GW Research Days 2016 - 2020

Studies on the pathophysiology and comorbidities associated with alopecia areata (AA) are limited. The purpose of this study was to determine the prevalence of androgen excess in AA and its subtypes, in relation to demographics and comorbidities. Medical records of 1,587 Patchy AA, AT, AU, and ophiasis patients seen in the Department of Dermatology at the Cleveland Clinic Foundation in Ohio between 2005 and 2015 were reviewed. Out of this cohort, 226 patients met the inclusion criteria. There is evidence that patients with AA had significantly greater prevalence of polycystic ovary syndrome (PCOS) than the general population (p<0.001). Androgen excess was identified in 42.5% (n=96) of the 226 patients with AA or any subtype (p<0.001). The androgen excess group was significantly more likely to present with irregular menses, hirsutism, adult acne, PCOS, and/or ovarian cysts (p<0.001). This study was limited by being retrospective. Our study demonstrated that AA is associated with androgen excess.

Perioperative Aspirin Recommendations In Children With Fenestrated Fontan Undergoing Adenotonsillectomy, Mariam Ashraf, Pamela A. Mudd, Jamie Mcelrath Schwartz, Karen Thompson

GW Research Days 2016 - 2020

Objective: Pediatric patients who have undergone the Fontan procedure are often on a long term aspirin regimen which can complicate perioperative management. In high risk procedures such as adenotonsillectomy, hemorrhage can be a significant complication and aspirin use may increase the risk. There is a need for evidence-based protocol on how to manage aspirin intake in the perioperative period for Fontan patients. We report the case of a patient with Fontan palliation who underwent adenotonsillectomy and presented with postoperative hemorrhage.

Methods: PubMed was searched for guidelines, case reports, and reviews on pediatric Fontan patients, adenotonsillectomy, and perioperative aspirin …
