Metachronous Periprosthetic Joint Infection In Patients With Multiple Arthroplasties At Index Infection, Devin Young, Daniel Nikolaidis, Andrew Steffensmeier, Robert Runner, Mark Karadsheh

Posters

Periprosthetic joint infection (PJI) is a devastating complication of one of the most successful surgeries in medicine. About 1% to 2% of patients will develop PJI after primary total hip arthroplasty (THA) or primary total knee arthroplasty (TKA) [1]. The 5-year patient survival rate of THA PJI is estimated to be worse than that of common cancers, such as breast cancer [2]. The burden of this disease is likely to increase exponentially as the population ages and the number of patients undergoing total joint arthroplasties increases in the future [3].

Most devastating is what Murray et al deem as metachronous …


Mechanisms Of Behavioral Change In Hosts Of Toxoplasma Gondii: A Review, Olivia Grimsley May 2025

Mechanisms Of Behavioral Change In Hosts Of Toxoplasma Gondii: A Review, Olivia Grimsley

Senior Honors Theses

The parasite Toxoplasma gondii is a highly ubiquitous parasite that latently infects an estimated 33% percent of the global population. Toxoplasmosis is of obvious clinical significance due to the extremely high risks to the unborn who contract it congenitally. Less attention has been given to a more subtle aspect of latent infection, which is the behavioral alterations that are commonly experienced by those who contract the parasite. Infected individuals commonly display a variety of altered behaviors, such as increased aggression and risk-seeking behaviors, depression, higher tendency towards suicide and self-directed violence, a loss of fear response, and a greatly increased …

Evaluation Of Human Mesenchymal Stromal Cells (Msc) As An Adjuvant Therapeutic For Chronic Lyme Disease, Matthew Teryek May 2025

Evaluation Of Human Mesenchymal Stromal Cells (Msc) As An Adjuvant Therapeutic For Chronic Lyme Disease, Matthew Teryek

Rowan-Virtua Research Day

Background: Lyme disease, caused by the spirochetal bacterium Borrelia burgdorferi, is the most prevalent vector-borne illness in the Northern Hemisphere. If undiagnosed or untreated, the disease progresses through multiple stages of increasing clinical severity. While antibiotics such as doxycycline and ceftriaxone are the current standard of care, patients with chronic or late-stage Lyme disease may require additional therapeutic interventions.

Rationale: Human mesenchymal stem cells (MSCs) are of growing clinical interest due to their immunomodulatory properties, low immunogenicity, and potential to promote tissue repair. These characteristics position MSCs as promising adjuvant therapies for chronic Lyme disease, with the potential to …

Igg4-Related Autoimmune Pancreatitis In Patients With Prior Occupational Exposure: A Case Report And Review Of Risks Concerning Blue-Collared Workers, Zachary A. Coren, Justin Le, Jason Tran, Nicholas Moscardelli, Krish Patel, Joshua Coren

Rowan-Virtua Research Day

Autoimmune pancreatitis (AIP), a manifestation of IgG4-related disease (IgG4-RD), is a rare, often misdiagnosed condition that can closely mimic pancreatic cancer, particularly in its clinical and radiographic presentation. We report the case of a 76-year-old retired plumber who presented with painless jaundice and was initially suspected to have pancreatic cancer based on imaging findings. Subsequent endoscopic evaluation, biopsy, and markedly elevated serum IgG4 levels led to a diagnosis of type 1 AIP. Treatment with corticosteroids resulted in rapid clinical improvement and reduction in IgG4 levels, confirming the diagnosis.

This case highlights the diagnostic challenges of AIP, especially among blue-collar workers …

Rowan-Virtua Research Day

The advent of immunomodulatory therapies and their ever-expanding number of treatment indications necessitates the understanding of their associated complications. Neutropenic fever serves as an example of these complications often encountered in clinical practice. Although neutropenic fever can result from virtually any pathogen, episodes of the syndrome secondary to tick-borne illness remain relatively undocumented in the scientific literature. In the case presented, a 77-year-old female with a pertinent past medical history of smoldering IgG multiple myeloma on active immunosuppressive therapy presented with a first-time episode of neutropenic fever likely secondary to tick-borne illness. Through this overview of a broader report, attention …

Case Report: Pigtail Suprapubic Catheter Placement In A Patient With Acute Urinary Retention And Abdominal Mesh, Clara Keum, Zamran Masih, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute urinary retention (AUR) is a urological emergency that requires immediate bladder decompression and management of the underlying condition to prevent further complications such as urinary tract infection and renal failure. When standard urethral catheterization is not feasible, a suprapubic catheter can be used to achieve adequate bladder drainage. However, in patients with structural or anatomical challenges, such as the presence of surgical mesh, suprapubic catheter placement can be difficult. This case report presents the successful placement of an 8.5 French pigtail catheter and urinary drainage in an 86-year-old male with abdominal mesh who presented with AUR.

An Unusual Cause Of Sepsis: Capnocytophaga Canimorsus, Capnocytophaga, Christopher Dellmyer, Kishan B. Patel

Rowan-Virtua Research Day

Septic shock can be caused by numerous different pathogens. A few of the more common causes are Streptococcus Pneumoniae, Staphylococcus Aureus, Escherichia Coli, Pseudomonas Aeruginosa, and Candida Albicans. Although these are the pathogens involved in the majority of septic shock cases, it is imperative to take the entire clinical picture into account when treating a patient with septic shock. Here we will discuss a seemingly unimpressive dog bite leading to Capnocytophaga canimorsus bacteremia, septic shock and end organ failure.

Case Report: Haemophilus Influenzae Meningitis In A 65 Year Old Female, Kaywan Saed, Russell Mordecai

Rowan-Virtua Research Day

We report a case of a 65-year-old female who presented with fever, altered mental status, and neck stiffness. Cerebrospinal fluid (CSF) analysis confirmed Haemophilus influenzae meningitis. The differential diagnosis of bacterial meningitis in older adults is broad and includes Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes, and Haemophilus influenzae. However, in the post-Hib vaccine era, non-typeable H. influenzae has emerged as a significant cause of invasive disease in older adults, particularly in those with underlying comorbidities.

Older patients often present with atypical symptoms, which may delay diagnosis and treatment. In this case, early recognition and prompt administration of empiric antibiotic therapy …


The Impact Of Emergency Room Overcrowding On The Incidence Of Healthcare-Acquired Infections Among Patients, Hayya Ali May 2025

The Impact Of Emergency Room Overcrowding On The Incidence Of Healthcare-Acquired Infections Among Patients, Hayya Ali

Rowan-Virtua Research Day

Emergency department (ED) visits are vital components of healthcare delivery, serving as the primary site for acute medical care, particularly for individuals with urgent medical needs. The ED is among the most crowded hospital units. The fast-paced setting and over-crowdedness of an emergency room have become the reality of every hospital across the United States. Overcrowding causes problems for patients and staff, which include the risk of contracting healthcare-acquired infections. This is due to several factors that in most cases lead to an increase in the number of people within the ED, an increase in mortality and morbidity, and a …

Cooper Rowan Medical Journal

Drug-induced hyperpigmentation is responsible for up to 20% of acquired hyperpigmentation cases, especially among the elderly population. The pathogenesis varies depending on the medication involved and may include melanin accumulation, drug deposition, production of special pigments, and iron deposition. We report the case of an elderly, immunocompromised patient with a history significant for leukemia presenting with black-blue hyperpigmentation of the upper and lower extremities, associated with iron deposition following levofloxacin exposure.


A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner May 2025

A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner

All Theses

Toxoplasmosis is a worldwide, yet often overlooked, parasitic disease caused by the protozoan parasite, Toxoplasma gondii. The parasite is capable of infecting humans and almost all warm-blooded vertebrates. Over a million people are infected in the United States with toxoplasmosis each year. Most infections are asymptomatic but severe cases can lead to vision impairment, neurological disorders, and congenital birth defects. T. gondii is transmitted through undercooked meat, infected feline feces, or contaminated water and soil. The burden of T. gondii infection is most notable in livestock, felines, and immunocompromised humans. Despite being a widespread disease, toxoplasmosis is neglected in …


Detection Of Covid-19 Variants, Christina Aglieco May 2025

Detection Of Covid-19 Variants, Christina Aglieco

Honors Scholar Theses

The outbreak of Covid-19 in December 2019 was devastating to many but led to major advancements in vaccine research and development. The development of a vaccine against SARS-CoV-2 infection offers protection for the public but cannot eliminate the risk of contracting Covid-19 due to the many viral mutations since the initial wild-type strain isolation in 2019. Analysis of these viral mutations will allow for the development of vaccines with greater protection against the new variants of the coronavirus. Secondary to Covid-19 infection seen in the pediatric population is Multisystem Inflammatory Syndrome in Children or MIS-C. Through qPCR analysis of pediatric …

The Role Of Myosin L In The Survival Of Toxoplasma Gondii And The Importance Of Mlc1 For In Vitro And In Vivo Myosin F Motility, Victoria K. Yi

Honors Scholar Theses

My thesis discusses the work that I have conducted on two myosins in Toxoplasma gondii, which is an obligate intracellular parasite that has chronically infected around 10% of the American population. It causes toxoplasmosis and severe health consequences for individuals with compromised immune systems or when infections occur in utero. However, immunocompetent individuals are asymptomatic or present with subclinical symptoms. In the Heaslip lab, I investigated two myosins in the parasite: Myosin L and Myosin F. MyoL is an uncharacterized motor that localizes at the apical end of the parasite. It was shown to be important for parasite …

Efficacy Of Stem Cell Therapy Versus Standard Drug Therapy In Adults With Heart Failure, Evie Reynolds May 2025

Efficacy Of Stem Cell Therapy Versus Standard Drug Therapy In Adults With Heart Failure, Evie Reynolds

Physician Assistant Scholarly Project Papers

Myocardial infarction (MI) or other damage to the heart tissue may result in ischemia, and because cardiomyocytes have limited regenerative capacity, this often leads to the development of heart failure (HF). Typical symptoms of HF include dyspnea, edema, cough, fatigue, and chest pain, which arises from fluid overload and congestion. Current medical treatments focus on alleviating these symptoms through loop diuretics, which reduce fluid accumulation but do not treat the underlying ischemic damage. Recent studies have shifted focus towards stem cell therapy, which have shown potential to differentiate into cardiomyocytes and regenerate ischemic heart tissue. A comprehensive search of databases …

Pseudomonas Aeruginosa Exoenzyme Y Enzymatic Activity Inhibits Exoenzyme S-Induced Caspase Activation But Not Cytotoxicity In Pulmonary Microvascular Endothelial Cells, Connor Holm

Honors Theses

Pseudomonas aeruginosa (P. aeruginosa) is the most common cause of ventilator-associated pneumonia in intensive care unit patients. P. aeruginosa utilizes a type III secretion system that injects exoenzymes U, S, T, and/or Y into the host cell cytosol. A majority of clinically isolated P. aeruginosa strains express ExoY often in combination with ExoU and ExoT, or ExoS and ExoT. Host signaling mechanisms in response to intoxication with individual exoenzymes have been extensively studied, yet little is known about host cell response to co-intoxication. In this study, pulmonary microvascular endothelial cells (PMVECs) were infected with P. aeruginosa strains expressing different combinations …
