Design For Success: Identifying A Process For Transitioning To An Intensive Online Course Delivery Model In Health Professions Education., Paige L Mcdonald, Kenneth J Harwood, Joan T Butler, Karen S Schlumpf, Carson W Eschmann, Daniela Drago

Clinical Research and Leadership Faculty Publications

Intensive courses (ICs), or accelerated courses, are gaining popularity in medical and health professions education, particularly as programs adopt e-learning models to negotiate challenges of flexibility, space, cost, and time. In 2014, the Department of Clinical Research and Leadership (CRL) at the George Washington University School of Medicine and Health Sciences began the process of transitioning two online 15-week graduate programs to an IC model. Within a year, a third program also transitioned to this model. A literature review yielded little guidance on the process of transitioning from 15-week, traditional models of delivery to IC models, particularly in online learning …

Dual-Display Laparoscopic Laser Speckle Contrast Imaging For Real-Time Surgical Assistance, Jaepyeong Cha, Corey Zheng, Lung Wai Lau

Pediatrics Faculty Publications

Laser speckle contrast imaging (LSCI) utilizes the speckle pattern of a laser to determine the blood flow in tissues. The current approaches for its use in a clinical setting require a camera system with a laser source on a separate optical axis making it unsuitable for minimally invasive surgery (MIS). With blood flow visualization, bowel viability, for example, can be determined. Thus, LSCI can be a valuable tool in gastrointestinal surgery. In this work, we develop the first-of-its-kind dual-display laparoscopic vision system integrating LSCI with a commercially available 10mm rigid laparoscope where the laser has the same optical axis as …

Medication Adherence And Its Implications For Clinical Research: An Example From Low Income, Urban Young Adults Living With Hiv/Aids, Kathleen A. Thoma

Clinical Research and Leadership Faculty Posters and Presentations

Consistent medication adherence by study participants is essential for producing valid and reliable safety and efficacy data in clinical trials. Adherence to investigational medications can be a challenge, particularly for study participants who have complex medication regimens, a stigmatized illness such as HIV/AIDS or a mental health disorder, and risk factors for poor adherence such as young or old age, poor health status, cognitive issues, low health literacy, and low socioeconomic status. A deep understanding of the study population’s beliefs, attitudes, motivations, and prior experiences regarding medication adherence can assist clinical research professionals with predicting medication adherence potential during the …

HIV infection is associated with the increased risk of cardiovascular disease (CVD), even in patients successfully treated with the combination antiretroviral therapy (cART). However, the relationship between HIV, cART, and pathogenesis of CVD remains controversial. In the present study, we evaluated the carotid intima-media thickness (CIMT), a surrogate marker of atherosclerosis, in HIV-infected subjects receiving or not receiving cART. One hundred nine newly diagnosed HIV-infected subjects and one hundred nine uninfected age-matched controls (all males) without the history of CVD, hypertension, or diabetes were recruited into the present study. Cross-sectional analysis at baseline (BL) showed significantly increased levels of triglycerides …

Patients often present at the onset of menarche with abdominal pain and a pelvic mass from an obstructed hemivagina. We report a child who presented with a febrile urinary tract infection and upon further workup was found to have OHVIRA.

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 …

Opioid Administration And Prescribing In Older Adults In U.S. Emergency Departments (2005-2015)., Erin M Marra, Maryann Mazer-Amirshahi, Peter Mullins, Jesse M Pines

Emergency Medicine Faculty Publications

Introduction: We assess trends in opioid administration and prescribing from 2005-2015 in older adults in United States (U.S.) emergency departments (ED).

Methods: We analyzed data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) survey from 2005 to 2015. ED visits for painful conditions were selected and stratified by age (18-64, 65-74, 75-84, ≥ 85 years). We analyzed trends in opioid administration in the ED and prescribing at discharge to encounters ≥ 65 and assessed predictors of use using survey-weighted chi-square tests and logistic regression. Trends in the use of five commonly prescribed opioids were also explored.

Results: Opioid administration …

Psychiatry and Behavioral Sciences Faculty Publications

BACKGROUND: Evidence for the effectiveness of psychological treatments in low- and middle-income countries is increasing. However, there is a lack of systematic approaches to guide implementation in government health systems. The objective of this study was to address this gap by employing the Replicating Effective Programs (REP) framework to guide contextualization of a psychological treatment in the Uganda public health system for caregivers of children affected by nodding syndrome, a neuropsychiatric disorder endemic to Sub-Saharan Africa associated with high morbidity and disability.

METHODS: To contextualize a psychological treatment, we followed the four components of the REP framework: pre-conditions, pre-implementation, implementation, …

High-Risk Advanced Maternal Age And High Parity Pregnancy: Tackling A Neglected Need Through Formative Research And Action., Khadidiatou Ndiaye, Erin Portillo, Dieneba Ouedraogo, Allison Mobley, Stella Babalola

Global Health Faculty Publications

Pregnancy among women of advanced maternal age (those 35 years or older) or among women of high parity (those having had 5 or more births) is linked to maternal and infant mortality. Yet little is known about the drivers of these pregnancies as they are often neglected in existing family planning and reproductive health programs. To better understand the context in which advanced maternal age and high parity pregnancies occur and the acceptability of discussing associated pregnancy risks, the Health Communication Capacity Collaborative (HC3) conducted formative qualitative research between January and March 2015 on the perception and determinants of such …

The Role Of Communities In Mental Health Care In Low- And Middle-Income Countries: A Meta-Review Of Components And Competencies., Brandon A Kohrt, Laura Asher, Anvita Bhardwaj, Mina Fazel, Mark J D Jordans, Byamah B Mutamba, Abhijit Nadkarni, Gloria A Pedersen, Daisy R Singla, Vikram Patel

Psychiatry and Behavioral Sciences Faculty Publications

Abstract

Community-based mental health services are emphasized in the World Health Organization’s Mental Health Action Plan, the World Bank’s Disease Control Priorities, and the Action Plan of the World Psychiatric Association. There is increasing evidence for effectiveness of mental health interventions delivered by non-specialists in community platforms in low- and middle-income countries (LMIC). However, the role of community components has yet to be summarized. Our objective was to map community interventions in LMIC, identify competencies for community-based providers, and highlight research gaps. Using a review-of-reviews strategy, we identified 23 reviews for the narrative synthesis. Motivations to employ community …

Emerging Cellular And Molecular Strategies For Enhancing Central Nervous System (Cns) Remyelination., Mohammad Abu-Rub, Robert H Miller

Anatomy and Regenerative Biology Faculty Publications

Myelination is critical for the normal functioning of the central nervous system (CNS) in vertebrates. Conditions in which the development of myelin is perturbed result in severely compromised individuals often with shorter lifespans, while loss of myelin in the adult results in a variety of functional deficits. Although some form of spontaneous remyelination often takes place, the repair process as a whole often fails. Several lines of evidence suggest it is feasible to develop strategies that enhance the capacity of the CNS to undergo remyelination and potentially reverse functional deficits. Such strategies include cellular therapies using either neural or mesenchymal …

Tgf-Β Sustains Tumor Progression Through Biochemical And Mechanical Signal Transduction., Robert L Furler, Douglas F Nixon, Christine A Brantner, Anastas Popratiloff, Christel H Uittenbogaart

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Transforming growth factor β (TGF-β) signaling transduces immunosuppressive biochemical and mechanical signals in the tumor microenvironment. In addition to canonical SMAD transcription factor signaling, TGF-β can promote tumor growth and survival by inhibiting proinflammatory signaling and extracellular matrix (ECM) remodeling. In this article, we review how TGF-β activated kinase 1 (TAK1) activation lies at the intersection of proinflammatory signaling by immune receptors and anti-inflammatory signaling by TGF-β receptors. Additionally, we discuss the role of TGF-β in the mechanobiology of cancer. Understanding how TGF-β dampens proinflammatory responses and induces pro-survival mechanical signals throughout cancer development is critical for designing therapeutics that …

Sources And Fates Of Carbamyl Phosphate: A Labile Energy-Rich Molecule With Multiple Facets., Dashuang Shi, Ljubica Caldovic, Mendel Tuchman

Genomics and Precision Medicine Faculty Publications

Carbamyl phosphate (CP) is well-known as an essential intermediate of pyrimidine and arginine/urea biosynthesis. Chemically, CP can be easily synthesized from dihydrogen phosphate and cyanate. Enzymatically, CP can be synthesized using three different classes of enzymes: (1) ATP-grasp fold protein based carbamyl phosphate synthetase (CPS); (2) Amino-acid kinase fold carbamate kinase (CK)-like CPS (anabolic CK or aCK); and (3) Catabolic transcarbamylase. The first class of CPS can be further divided into three different types of CPS as CPS I, CPS II, and CPS III depending on the usage of ammonium or glutamine as its nitrogen source, and whether

Lung Cancer Risk And Low (≤50 Μg/L) Drinking Water Arsenic Levels For Us Counties (2009⁻2013)-A Negative Association., Steven H Lamm, Isabella J Boroje, Hamid Ferdosi, Jaeil Ahn

Pediatrics Faculty Publications

While epidemiologic studies clearly demonstrate drinking water with high levels of arsenic as a significant risk factor for lung cancer, the evidence at low levels (≤50 μg/L) is uncertain. Therefore, we have conducted an ecological analysis of recent lung cancer incidence for US counties with a groundwater supply of <50 μg/L, the historical limit for both the EPA and WHO. Data sources used included USGS for arsenic exposure, NCI for lung cancer outcome, and CDC and US Census Bureau forcovariates. Poisson log-linear models were conducted for male, female, and total populations using for exposure median county arsenic level, maximum arsenic level ≤50 μg/L, and ≥80% population groundwater dependency. Statistically significant negative associations were found in each of the six models in which the exposure was limited to those who had major exposure (≥80% dependency) to low-levels of arsenic (≤50 μg/L). This is the first large ecological study of lung cancer risk from drinking water arsenic levels that specifically examined the dose-response slope for populations whose exposure was below the historical limit of ≤50 μg/L. The models for each of the three populations (total; male; female) demonstrated an association that is both negative and statistically significant.

Ultrasound-Guided Introital Drainage Of Pyometrocolpos, I Kim, Ranjith Vellody, Hans G. Pohl, Karun Sharma, Kabir Yadav

Radiology Faculty Publications

Pyometrocolpos can be caused by congenital malformations such as distal vaginal atresia and imperforate hymen. Patients usually present with obstructive urinary tract infections, acute kidney injury, or sepsis. Percutaneous drainage of the infected fluid can help treat the patient; however, recurrence is of concern. In this case report, we present a case of a child with recurrent pyometrocolpos due to distal vaginal atresia despite initial percutaneous drainage. To our knowledge, this is the first report of ultrasound-guided introital drainage of pyometrocolpos with relief of symptoms obviating the need for repeat drainage or immediate surgery. © 2017
