Of Monkeys And Men: Immunomic Profiling Of Sera From Humans And Non-Human Primates Resistant To Schistosomiasis Reveals Novel Potential Vaccine Candidates., Mark S Pearson, Luke Becker, Patrick Driguez, Neil D Young, Soraya Gaze, Jeffrey M. Bethony, +12 Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosoma haematobium affects more than 100 million people throughout Africa and is the causative agent of urogenital schistosomiasis. The parasite is strongly associated with urothelial cancer in infected individuals and as such is designated a group I carcinogen by the International Agency for Research on Cancer. Using a protein microarray containing schistosome proteins, we sought to identify antigens that were the targets of protective IgG1 immune responses in S. haematobium-exposed individuals that acquire drug-induced resistance (DIR) to schistosomiasis after praziquantel treatment. Numerous antigens with known vaccine potential were identified, including calpain (Smp80), tetraspanins, glutathione-S-transferases, and glucose transporters (SGTP1), as well …

Emergency Department Ultrasound Probe Infection Control: Challenges And Solutions, Hamid A. Shokoohi, Paige Armstrong, Ryan Tansek

Emergency Medicine Faculty Publications

Point-of-care ultrasound (US) has become a cornerstone in the diagnosis and treatment of patients in the emergency department (ED). Despite the beneficial impact on patient care, concern exists over repeat use of probes and the role as a vector for pathogen transmission. US probes are used for various applications, with the level of infection risk, based on the Spaulding Classification, ranging from noncritical with common practice to semicritical with endocavitary probes. To date, the most closely studied organisms are Staphylococcus aureus and human papilloma virus. Current evidence does confirm probe colonization but has not established a causative role in human …

Do Emergency Department Patients Receive A Pathological Diagnosis? A Nationally-Representative Sample., Leana S. Wen, Janice A. Espinola, Joshua M. Mosowsky, Carlos A. Camargo

Emergency Medicine Faculty Publications

Introduction

Understanding the cause of patients’ symptoms often requires identifying a pathological diagnosis. A single-center study found that many patients discharged from the emergency department (ED) do not receive a pathological diagnosis. We analyzed 17 years of data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) to identify the proportion of patients who received a pathological diagnosis at ED discharge. We hypothesized that many patients do not receive a pathological diagnosis, and that the proportion of pathological diagnoses increased between 1993 and 2009.

Methods

Using the NHAMCS data from 1993–2009, we analyzed visits of patients age ≥18 years, discharged …

Solving The Worldwide Emergency Department Crowding Problem - What Can We Learn From An Israeli Ed?, Jesse M Pines, Steven L Bernstein

Emergency Medicine Faculty Publications

ED crowding is a prevalent and important issue facing hospitals in Israel and around the world, including North and South America, Europe, Australia, Asia and Africa. ED crowding is associated with poorer quality of care and poorer health outcomes, along with extended waits for care. Crowding is caused by a periodic mismatch between the supply of ED and hospital resources and the demand for patient care. In a recent article in the Israel Journal of Health Policy Research, Bashkin et al. present an Ishikawa diagram describing several factors related to longer length of stay (LOS), and higher levels of ED …

Impact Of Condition Specific Camps On Resiliency And Adaptive Behavior In Children With Heart Conditions, Jeanette Fong, Sandra Cushner-Weinstein

GW Research Days 2015

Objectives: Resilience is the ability to adapt in stressful situations and overcome adversity through the use of effective coping strategies. Previous studies have demonstrated that condition-specific camps designed for children with epilepsy can increase adaptive coping skills including social interactions, cooperation, initiative, and communication in participants over a three-year period ^[1,2]. Additionally, research indicates that as a group, individuals who live with chronic health disorders exhibit less hope and have worse health outcomes when compared to their normative peers. The aim of this study was to determine the impact of condition-specific camps on children with heart conditions.

Further Expansion Of Nested E-Modules To Address Anatomical Knowledge Retention In Medical Students Entering The Obstetrics And Gynecology Clinical Rotation, Abigail Armstrong, Jill A. Krapf, Kirsten Brown, Gisela Butera, Ellen F. Goldman, Rosalyn A. Jurjus

GW Research Days 2015

Previous work has shown that a curriculum that included computer-based teaching modules (“e-modules”) improved retention of preclinical concepts of gross anatomy, as medical students transitioned to the third-year OBGYN clerkship. However, data showed that deficiencies still remained in areas not addressed by the curriculum. Two of these areas were microscopic anatomy and embryology, where retention scores were 4% and 38%, respectively (Jurjus et al., unpublished). Based on this research, an expanded series of e-modules will be created to target these anatomical topics that still require improvement, specifically in microscopic anatomy and embryology: 1) Ultrasound in Pregnancy using Embryological Knowledge 2) …

Once Upon A Microscopic Slide: The Story Of Histology, Inaya Hussein, Mohamad Raad, Rawan Safa, Rosalyn A. Jurjus, Abdo Jurjus

Anatomy and Regenerative Biology Faculty Publications

For centuries, histology has maintained its remarkable place in the medical curriculum. However, its teaching has been influenced by the new technological advancement that has reshaped medicine teaching into a more modern student-friendly form. Since its inception in the 18th century, the discipline of histology has progressed hand in hand with the advancements in microscopy and microscopic technologies, including immunohistochemistry. In the traditional curriculum of USA medical schools, especially after the first Flexner’s report of 1910, histology was considered as very essential topic for a physician studying the “Art and Science” of medicine. In this era, the teaching relied more …

Clash Of The Titans: Medicaid Meets Private Health Insurance, Sara J. Rosenbaum

Health Policy and Management Faculty Publications

Throughout its first forty-eight years of life, the federal Medicaid statute lacked a viable insurance pathway for most low-income adults' ineligible for employer-sponsored coverage. In what is arguably the most important public health achievement since the enactment of Medicare and Medicaid fifty years ago, the Patient Protection and Affordable Care Act (ACA) fundamentally alters this picture. Building on earlier breakthroughs for children, the ACA restructures Medicaid to cover poor adults and juxtaposes its new architecture against an affordable and accessible private insurance market for people ineligible for employer-sponsored or government insurance.

Insistence On Sameness Relates To Increased Covariance Of Gray Matter Structure In Autism Spectrum Disorder., Ian W Eisenberg, Gregory L Wallace, Lauren Kenworthy, Stephen J Gotts, Alex Martin

Psychiatry and Behavioral Sciences Faculty Publications

BACKGROUND: Autism spectrum disorder (ASD) is characterized by atypical development of cortical and subcortical gray matter volume. Subcortical structural changes have been associated with restricted and repetitive behavior (RRB), a core component of ASD. Behavioral studies have identified insistence on sameness (IS) as a separable RRB dimension prominent in high-functioning ASD, though no simple brain-behavior relationship has emerged. Structural covariance, a measure of morphological coupling among brain regions using magnetic resonance imaging (MRI), has proven an informative measure of anatomical relationships in typical development and neurodevelopmental disorders. In this study, we use this measure to characterize the relationship between brain …

Pediatrics Faculty Publications

Pleuropulmonary blastoma (PPB) is the most frequent pediatric lung tumor and often the first indication of a pleiotropic cancer predisposition, DICER1 syndrome, comprising a range of other individually rare, benign and malignant tumors of childhood and early adulthood. The genetics of DICER1-associated tumorigenesis are unusual in that tumors typically bear neomorphic missense mutations at one of five specific “hotspot” codons within the RNase IIIb domain of DICER 1, combined with complete loss of function (LOF) in the other allele. We analyzed a cohort of 124 PPB children for predisposing DICER1 mutations and sought correlations with clinical phenotypes. Over …
