Moving On Up: A Case Study Of Hiv And Covid-Induced Guillain-Barre Syndrome, Victoria Wong Murray, Rebecca Chae, Isobel Moyer, Cindy Hou

Rowan-Virtua Research Day

COVID and HIV are both common diseases, with COVID affecting an estimated 775 million and HIV affecting 39 million people worldwide. Guillain-Barre is a rare but feared complication of immune stimulation in which the body generates autoantibodies against gangliosides, found in the nodes of Ranvier, in the myelin, and in the ganglia; causing ascending paralysis.

A mid-30s man with HIV maintained on Genvoya presented to the Jefferson Health New Jersey Early Intervention Program clinic with fatigue, fever, cough, and congestion and tested positive for SARS-CoV-2 on the following day. Two weeks later, he presented to the emergency department complaining of …

Pediatric Neurotropic Infection Alters Synaptic Development In The Developing Brain, Anuoluwapo Grace Fadare, Yashika S. Kamte, Manish N. Chandwani, Lauren A. O'Donnell

Rowan-Virtua Research Day

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …

‘Not So Atypical’: An Atypical Presentation Of West Nile Virus And Guillain-Barre Syndrome, Matthew Orap, Sana Tahir, Ugonna Ononuju, Naresh Kumar

Rowan-Virtua Research Day

Guillain-Barre Syndrome (GBS) is defined by acute areflexic paralysis, usually starting in the distal lower extremities, and ascending to the upper extremities. It is associated with albuminocytologic dissociation, which involves elevated protein levels and normal cell counts in the cerebrospinal fluid. One of the types of GBS, called Miller-Fischer Syndrome (MFS), is characterized by ophthalmoplegia, ataxia, and areflexia. This case report focuses on a 49-year-old male with an atypical presentation of Guillain-Barre syndrome. Guillain-Barre syndrome can be classically caused by Campylobacter jejuni. However, there can be other infectious causes as well, namely Cytomegalovirus, Epstein-Barr virus, Varicella-Zoster virus, …

Case Report: Varicella Zoster Virus Encephalitis Presenting With Monochorea, Chetna Thawani, Frank Wheeler

Rowan-Virtua Research Day

Meningoencephalitis is a broad range of symptoms as a sequela of inflammation of the CNS system. It is a diagnosis that is often missed, especially in atypical presentations. We describe a case of HSV encephalitis that presented to the ER afebrile with atypical arm movements, most similar to a monochorea, and discuss other cases in the literature of atypical presentations of this disease.

Chilling Complications: A Case Of Covid-Associated Cold Autoimmune Hemolytic Anemia (Aiha), Julian Coz, Kishan B. Patel

Rowan-Virtua Research Day

Cold Agglutinin disease (CAD) also known as Cold Autoimmune Hemolytic Anemia (AIHA) is a form of autoimmune hemolytic anemia wherein cold agglutinins (IgM autoantibodies against red blood cell (RBC) antigens) bind during cold temperatures causing clinical symptoms related to RBC agglutination resulting to hemolytic anemia. Clinicians should recognize that Cold Agglutinin disease can be secondary to an underlying pathology such as COVID-19. Here we describe an unusual case of Cold Agglutinin Autoimmune Hemolytic Anemia which was diagnosed in the Emergency Department with the presence of COVID-19 and with a hospital course complicated by acute deep vein thrombosis (DVT) and bilateral …

Institute for Human Development, East Africa

Introduction There are no published data on the long-term impact of invasive group B Streptococcus disease (iGBS) on economic costs or health-related quality of life (HRQoL) in low-income and middle-income countries. We assessed the impact of iGBS on healthcare utilisation, costs and HRQoL in Argentina, India, Kenya, Mozambique and South Africa.

Methods Inpatient and outpatient visits, out-of-pocket (OOP) healthcare payments in the 12 months before study enrolment, and health-state utility of children and caregivers (using the EuroQol 5-Dimensions-3-Level) were collected from iGBS survivors and an unexposed cohort matched on site, age at recruitment and sex. We used logistic or Poisson …

Uncovering Capillary Endothelial Cells Response During Lung Injury-Repair, Celine Shuet Lin Kong

Dissertations and Theses (Open Access)

Once thought to be a homogenous population, capillary endothelial cells (ECs) have embodied organotypic specialization and heterogenous properties, both during homeostasis and tissue injury. In the lung, capillary ECs consist of two distinct populations, CAP1 and CAP2s; how each population responds to diverse tissue injury is incompletely understood. In this thesis, I report the induction and function of a truncated isoform of Ntrk2, Ntrk2^-tk (lacking the tyrosine kinase domain) in multiple injury models. Using a combinatorial approach of single-cell multiome, mouse genetics and viral infection models, I found that Ntrk2^-tk is broadly induced in CAP1s after the initial …

A Comparative Analysis Of Hiv/Aids In France And The United States: Historical Context And Preventative Actions, Rebecca A. Liebsack

Honors Program: Senior Projects (Public)

The HIV/AIDS pandemic is the result of transmission of a zoonotic disease known as simian immunodeficiency virus. The pandemic has had profound social and economic consequences and continues to be present today. France and the United States’ response to the discovery of HIV will be compared and the impact that HIV/AIDS had on their countries and future responses. They had rather similar responses, however, the United States had a slower initial response compared to France. Both had similar takeaways such as aiming at improving prevention and utilizing tactics developed during the start of the pandemic like frequent testing and vaccines.

Exploring Binding Pockets In The Conformational States Of The Sars-Cov-2 Spike Trimers For The Screening Of Allosteric Inhibitors Using Molecular Simulations And Ensemble-Based Ligand Docking, Grace Gupta, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Understanding mechanisms of allosteric regulation remains elusive for the SARS-CoV-2 spike protein, despite the increasing interest and effort in discovering allosteric inhibitors of the viral activity and interactions with the host receptor ACE2. The challenges of discovering allosteric modulators of the SARS-CoV-2 spike proteins are associated with the diversity of cryptic allosteric sites and complex molecular mechanisms that can be employed by allosteric ligands, including the alteration of the conformational equilibrium of spike protein and preferential stabilization of specific functional states. In the current study, we combine conformational dynamics analysis of distinct forms of the full-length spike protein trimers and …

Ischemic Colitis In A Middle-Aged Man With Covid-19: Case Report And Review Of Literature, Lara Appiah, Subhasis Misra, Stephen Jones

HCA Healthcare Journal of Medicine

Introduction

Coronavirus disease 2019 (COVID-19) was a pandemic that began in 2019 and continues to have morbid and deadly consequences throughout the world. During the beginning of the pandemic, many considered older adults and immunocompromised younger adults to be the only populations at risk for the severe consequences of COVID-19. Throughout the pandemic, this was proven wrong with several case reports and studies showing that relatively younger adults can also suffer serious consequences from this perplexing virus.

Case Presentation

We report a rare case of ischemic colitis in a 42-year-old obese man who presented to the emergency department with quintessential …

Pharmacy Faculty Articles and Research

The emergence of multidrug-resistant (MDR) strains causes severe problems in the treatment of microbial infections owing to limited treatment options. Antimicrobial peptides (AMPs) are drawing considerable attention as promising antibiotic alternative candidates to combat MDR bacterial and fungal infections. Herein, we present a series of small amphiphilic membrane-active cyclic peptides composed, in part, of various nongenetically encoded hydrophilic and hydrophobic amino acids. Notably, lead cyclic peptides 3b and 4b showed broad-spectrum activity against drug-resistant Gram-positive (MIC = 1.5–6.2 µg/mL) and Gram-negative (MIC = 12.5–25 µg/mL) bacteria, and fungi (MIC = 3.1–12.5 µg/mL). Furthermore, lead peptides displayed substantial antibiofilm action comparable …
