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 …

The Oral Bacterial Communities Of Children With Well-Controlled Hiv Infection And Without Hiv Infection., Brittany E. Goldberg, Emmanuel F. Mongodin, Cheron E. Jones, Michelle Chung, Claire M. Fraser, Anupama R. Tate, Steven L. Zeichner

Pediatrics Faculty Publications

The oral microbial community (microbiota) plays a critical role in human health and disease. Alterations in the oral microbiota may be associated with disorders such as gingivitis, periodontitis, childhood caries, alveolar osteitis, oral candidiasis and endodontic infections. In the immunosuppressed population, the spectrum of potential oral disease is even broader, encompassing candidiasis, necrotizing gingivitis, parotid gland enlargement, Kaposi's sarcoma, oral warts and other diseases. Here, we used 454 pyrosequencing of bacterial 16S rRNA genes to examine the oral microbiome of saliva, mucosal and tooth samples from HIV-positive and negative children. Patient demographics and clinical characteristics were collected from a cross-section …

Temporal Order Of Rnase Iiib And Loss-Of-Function Mutations During Development Determines Phenotype In Dicer1 Syndrome: A Unique Variant Of The Two-Hit Tumor Suppression Model [V1; Ref Status: Approved With Reservations 1, Http://F1000r.Es/5l9], Mark Brenneman, Amanda Field, Jiandong Yang, Gretchen Williams, Leslie A. Doros, Christopher T. Rossi, Heather A. Gordish-Dressman, D. Ashley Hill, Et Al.

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 …

Β2-Adrenergic Receptor Promoter Haplotype Influences The Severity Of Acute Viral Respiratory Tract Infection During Infancy: A Prospective Cohort Study., Pingsheng Wu, Emma K. Larkin, Sara S Reiss, Kecia N Carroll, Marshall L. Summar, Patricia A Minton, +6 Additional Authors

Pediatrics Faculty Publications

BACKGROUND: Despite the significant interest in β2-Adrenergic receptor (ADRB2) polymorphisms related to asthma, whether ADRB2 genetic variants are similarly associated with acute respiratory tract infections have not been studied. We hypothesized that genetic variants in ADRB2 associated with a response to asthma therapy during an asthma exacerbation were also associated with severity of acute respiratory tract infections.

METHODS: To test this hypothesis, we genotyped 5 common polymorphisms in the promoter region and coding block of the ADRB2 gene (loci -2387, -2274, -1343, +46, and +79) from 374 Caucasian and African American term infants who were enrolled at the time of …

Differential Expression Of The Nrf2-Linked Genes In Pediatric Septic Shock., Jocelyn R Grunwell, Scott L Weiss, Natalie Z Cvijanovich, Geoffrey L Allen, Neal J Thomas, Robert J. Freishtat, +10 Additional Authors

Pediatrics Faculty Publications

INTRODUCTION: Experimental data from animal models of sepsis support a role for a transcription factor, nuclear erythroid-related factor 2 p45-related factor 2 (Nrf2), as a master regulator of antioxidant and detoxifying genes and intermediary metabolism during stress. Prior analysis of a pediatric septic shock transcriptomic database showed that the Nrf2 response is a top 5 upregulated signaling pathway in early pediatric septic shock.

METHODS: We conducted a focused analysis of 267 Nrf2-linked genes using a multicenter, genome-wide expression database of 180 children with septic shock 10 years of age or younger and 53 healthy controls. The analysis involved RNA isolated …

Beyond Cd19: Opportunities For Future Development Of Targeted Immunotherapy In Pediatric Relapsed-Refractory Acute Leukemia., Haneen Shalabi, Anne Angiolillo, Terry J Fry

Pediatrics Faculty Publications

Chimeric antigen receptor (CAR) T cell therapy has been used as a targeted approach in cancer therapy. Relapsed and refractory acute leukemia in pediatrics has been difficult to treat with conventional therapy due to dose-limiting toxicities. With the recent success of CD 19 CAR in pediatric patients with B cell acute lymphoblastic leukemia (ALL), this mode of therapy has become a very attractive option for these patients with high-risk disease. In this review, we will discuss current treatment paradigms of pediatric acute leukemia and potential therapeutic targets for additional high-risk populations, including T cell ALL, AML, and infant ALL.

Intracellular Cd24 Disrupts The Arf-Npm Interaction And Enables Mutational And Viral Oncogene-Mediated P53 Inactivation., Lizhong Wang, Runhua Liu, Peiying Ye, Chunshu Wong, Guo-Yun Chen, Penghui Zhou, +11 Additional Authors

Pediatrics Faculty Publications

CD24 is overexpressed in nearly 70% human cancers, whereas TP53 is the most frequently mutated tumour-suppressor gene that functions in a context-dependent manner. Here we show that both targeted mutation and short hairpin RNA (shRNA) silencing of CD24 retard the growth, progression and metastasis of prostate cancer. CD24 competitively inhibits ARF binding to NPM, resulting in decreased ARF, increase MDM2 and decrease levels of p53 and the p53 target p21/CDKN1A. CD24 silencing prevents functional inactivation of p53 by both somatic mutation and viral oncogenes, including the SV40 large T antigen and human papilloma virus 16 E6-antigen. In support of the …

Acute Glomerular Diseases In Children, Kanwal Kher

Pediatrics Faculty Publications

Glomerulonephritis [GN] is one of the common acquired pediatric renal disorders encountered in clinical practice. The clinical manifestations include gross or microscopic hematuria, proteinuria, and nephrotic syndrome. Renal dysfunction and hypertension may also be present in many patients. Etiopathogenesis of GN can be idiopathic in a large majority, while some may result from infections or known immune disorders. Several of these disorders are now believed to arise from dysfunctions of podocytes and are grouped under the heading of “podocytopathies”. This review focuses on the clinical manifestations and management of the common forms of acute GN encountered in children.
