The Neurodevelopmental Perspective Of Surgical Necrotizing Enterocolitis: The Role Of The Gut-Brain Axis., Chariton Moschopoulos, Panagiotis Kratimenos, Ioannis Koutroulis, Bhairav V Shah, Anja Mowes, Vineet Bhandari

Pediatrics Faculty Publications

This state-of-the-art review article aims to highlight the most recent evidence about the therapeutic options of surgical necrotizing enterocolitis, focusing on the molecular basis of the gut-brain axis in relevance to the neurodevelopmental outcomes of primary peritoneal drainage and primary laparotomy. Current evidence favors primary laparotomy over primary peritoneal drainage as regards neurodevelopment in the surgical treatment of necrotizing enterocolitis. The added exposure to inhalational anesthesia in infants undergoing primary laparotomy is an additional confounding variable but requires further study. The concept of the gut-brain axis suggests that bowel injury initiates systemic inflammation potentially affecting the developing central nervous system. …

Pd-L1 Checkpoint Inhibition And Anti-Ctla-4 Whole Tumor Cell Vaccination Counter Adaptive Immune Resistance: A Mouse Neuroblastoma Model That Mimics Human Disease., Priya Srinivasan, Xiaofang Wu, Mousumi Basu, Christopher Rossi, Anthony D Sandler

Pathology Faculty Publications

BACKGROUND: Adaptive immune resistance induces an immunosuppressive tumor environment that enables immune evasion. This phenomenon results in tumor escape with progression and metastasis. Programmed cell death-ligand 1 (PD-L1) expressed on tumors is thought to inhibit tumor-infiltrating lymphocytes (TILs) through programmed cell death 1 (PD1), enabling adaptive immune resistance. This study investigates the role of PD-L1 in both mouse and human neuroblastoma immunity. The consequence of PD-L1 inhibition is characterized in the context of an established whole tumor cell vaccine.

METHODS AND FINDINGS: A mouse model of neuroblastoma was investigated using an Id2 knockdown whole cell vaccine in combination with checkpoint …

Epha2/Ephrin-A1 Mediate Corneal Epithelial Cell Compartmentalization Via Adam10 Regulation Of Egfr Signaling., Nihal Kaplan, Rosa Ventrella, Han Peng, Sonali Pal-Ghosh, Constadina Arvanitis, Joshua Z Rappoport, Brian J Mitchell, Mary Ann Stepp, Robert M Lavker, Spiro Getsios

Anatomy and Regenerative Biology Faculty Publications

Purpose: Progenitor cells of the limbal epithelium reside in a discrete area peripheral to the more differentiated corneal epithelium and maintain tissue homeostasis. What regulates the limbal-corneal epithelial boundary is a major unanswered question. Ephrin-A1 ligand is enriched in the limbal epithelium, whereas EphA2 receptor is concentrated in the corneal epithelium. This reciprocal pattern led us to assess the role of ephrin-A1 and EphA2 in limbal-corneal epithelial boundary organization.

Methods: EphA2-expressing corneal epithelial cells engineered to express ephrin-A1 were used to study boundary formation in vitro in a manner that mimicked the relative abundance of these juxtamembrane signaling proteins in …

Spotlight On Once-Monthly Long-Acting Injectable Aripiprazole And Its Potential As Maintenance Treatment For Bipolar I Disorder In Adult Patients., Vanessa Torres-Llenza, Pooja Lakshmin, Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

The lack of long-term medication adherence is a challenge in the treatment of bipolar disorder, particularly during the maintenance phase when symptoms are less prominent. The rate of nonadherence is ~20%-60% depending on how strict a definition is used. Nonadherence worsens the course of bipolar disorder and can add hundreds of thousands of dollars to the lifetime cost of treating the illness. Long-acting injectable (LAI) medication is an attractive alternative to daily dosing of oral medication, especially among patients who are ambivalent about treatment. The purpose of this paper is to review the evidence for the safety and efficacy of …

Review Of Risk Assessment Tools To Predict Morbidity And Mortality In Elderly Surgical Patients Brief Title: Review Of Surgical Risk Assessment Tools, Gilgamesh Eamer, Mohamed Al-Amoodi, Jayna Holroyd-Leduc, Darryl Rolfson, Lindsey Warkentin, Rachel Khadaroo

School of Medicine and Health Sciences Student Works

Background

Informed surgical consent requires accurate estimation of risks and benefits. Multiple risk assessment tools are available; however, most are not widely used or are specific to certain interventions. Assessing surgical risk is especially challenging in elderly patients because of their range of comorbidities, level of frailty, or severity of illness and a number of available surgical interventions.

Data sources

We searched MEDLINE from January 2014 to July 2017 for studies that used risk assessment tools in studies on elderly surgical patients. We then sought the original articles describing each assessment tool and subsequent validation studies.

Conclusions

We identified risk …

Genomic Differences Between Nasal Staphylococcus Aureus From Hog Slaughterhouse Workers And Their Communities., Yaqi You, Li Song, Bareng A S Nonyane, Lance B Price, Ellen K Silbergeld

Environmental and Occupational Health Faculty Publications

New human pathogens can emerge from the livestock-human interface and spread into human populations through many pathways including livestock products. Occupational contact with livestock is a risk factor for exposure to those pathogens and may cause further spreading of those pathogens in the community. The current study used whole genome sequencing to explore nasal Staphylococcus aureus obtained from hog slaughterhouse workers and their community members, all of whom resided in a livestock-dense region in rural North Carolina. Sequence data were analyzed for lineage distribution, pathogenicity-related genomic features, and mobile genetic elements. We observed evidence of nasal S. aureus differences between …

Epidemiology Faculty Publications

INTRODUCTION: Mortality associated with in-utero HIV infection rises rapidly within weeks after birth. Very early infant diagnosis of HIV (VEID)-testing within 2 weeks of birth-followed by immediate initiation of antiretroviral therapy has potential to avert mortality associated with in-utero transmission. However, our understanding of acceptability and feasibility of VEID is limited.

METHODS: VEID was piloted in an observational prospective cohort of HIV-positive pregnant women and their infants in 13 Lesotho health facilities. Between March-July 2016, semi-structured interviews were conducted with HIV-positive women attending 6-week or 14-week postnatal visits and health workers (HWs) in 8 study facilities in 3 districts as …

Rhythm: An Open Source Imaging Toolkit For Cardiac Panoramic Optical Mapping, Christopher Gloschat, Kedar Aras, Shubnam Gupta, N. Rokhana Faye, Hanyu Zhang, Matthew W. Kay, Igor R Efimov, +Several Additional Authors

Pharmacology and Physiology Faculty Publications

Fluorescence optical imaging techniques have revolutionized the field of cardiac electrophysiology and advanced our understanding of complex electrical activities such as arrhythmias. However, traditional monocular optical mapping systems, despite having high spatial resolution, are restricted to a two-dimensional (2D) field of view. Consequently, tracking complex three-dimensional (3D) electrical waves such as during ventricular fibrillation is challenging as the waves rapidly move in and out of the field of view. This problem has been solved by panoramic imaging which uses multiple cameras to measure the electrical activity from the entire epicardial surface. However, the diverse engineering skill set and substantial resource …

Modeling The Relationship Between Women’S Perceptions And Future Intention To Use Institutional Maternity Care In The Western Highlands Of Guatemala, Emily Peca, John Sandberg

Global Health Faculty Publications

Background

Despite global gains, women in hard-to-reach areas are at a relatively higher risk of death and disability related to childbirth. Traditional methods of measuring satisfaction may mask negative experiences (such as disrespect and abuse) that can drive down demand for institutional care. Better measurement of women’s perceptions of care quality, especially among marginalized populations with historically low utilization of institutional care, are needed to inform how to improve services and foster greater utilization of (potentially life-saving) clinical care.

Methods

A population-based household survey was conducted in 15 purposively selected villages in the rural Western Highlands of Guatemala among women …

Antiretroviral Therapy Interruptions: Impact On Hiv Treatment And Transmission., Gueorgui Dubrocq, Natella Rakhmanina

Pediatrics Faculty Publications

Introduction: Successful management of pediatric and adult human immunodeficiency virus (HIV) disease includes lifelong administration of antiretroviral therapy (ART). The need for the continuous use of antiretroviral drugs throughout the life course poses a challenge to children, adolescents, and adults living with HIV and their caregivers. Historically, treatment interruptions have been viewed as a negative therapeutic strategy. Recently, however, treatment interruptions or treatment reduction strategies have become a focus of investigations as innovative approaches to the long-term management of HIV disease. Current challenges with treatment interruptions include identifying an appropriate timeframe for length of interruptions and identifying HIV patient populations …

Hiv Intervention For The Dc Community, Evelyn Rosales, Elias Belhocine, Daniel Ndagha, Tiana Young

DC Health and Academic Prep Program (DC HAPP)

Before the 1980s, the world had little to no knowledge about HIV. Now there has been research conducted on HIV/AIDs that has helped people prevent and be aware of their status. However, there is still an increasing amount of HIV cases in adults (18-34), especially in DC communities. Such disparities in HIV cases occur based on people’s race, gender, sexual orientation, income and geographical location. The social determinants of health also play a role in these cases such as poverty, access to care, stigma and racism. Our program will tackle these issues by providing an emphasis on existing programs by …

Simulations For Designing And Interpreting Intervention Trials In Infectious Diseases., M Elizabeth Halloran, Kari Auranen, Sarah Baird, Nicole E Basta, Steven E Bellan, +Several Additional Authors

Global Health Faculty Publications

BACKGROUND: Interventions in infectious diseases can have both direct effects on individuals who receive the intervention as well as indirect effects in the population. In addition, intervention combinations can have complex interactions at the population level, which are often difficult to adequately assess with standard study designs and analytical methods.

DISCUSSION: Herein, we urge the adoption of a new paradigm for the design and interpretation of intervention trials in infectious diseases, particularly with regard to emerging infectious diseases, one that more accurately reflects the dynamics of the transmission process. In an increasingly complex world, simulations can explicitly represent transmission dynamics, …
