The Role Of Heart Rate Variability In The Management Of Inflammatory Bowel Disease: A Scoping Review, Zarif A. Ladak, Krisha Patel, Dylan Bagley, Jeffery Powers

Rowan-Virtua Research Day

Complications associated with Inflammatory Bowel Disease (IBD) have an unclear pathophysiology. Heart Rate Variability (HRV) is a potent modality for monitoring autonomic nervous system function and may give insight into the timing of flares and complication development. Existing literature suggests a link between IBD complications and inflammation as well as inflammation and HRV. However, research directly exploring the relationship between HRV and IBD complications is limited. This review aims to examine the state of the science as it pertains to the relationship between HRV and IBD complications highlighting current knowledge gaps to guide future research. A search was conducted using …

Children Born To Mothers With Inflammatory Bowel Disease: A Review Of Pediatric Outcomes, Simran Gandhi, Kush Patel, Harmann Singh

Rowan-Virtua Research Day

Background: Inflammatory Bowel Disease (IBD), comprising Crohn’s disease and ulcerative colitis, frequently affects women during their reproductive years. While the impact of IBD on pregnancy has been widely studied, less is known about the long-term health outcomes in children born to affected mothers, particularly in the context of in utero exposure to immunosuppressive therapies.

Hypothesis: We hypothesize that children born to mothers with well-managed IBD experience normal growth and development, with minimal risk for immune-related complications, despite potential exposure to biologics and other IBD medications during gestation.

Methods: A literature review was conducted using PubMed and Google Scholar. Search terms …

Unusual Path: Gallstone Ileus With Pneumobilia And Jejunal Obstruction, Kristine Rubi, Kelly Schuitema, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We present a case of a 48-year-old female with two-day history of diffuse abdominal pain, nausea and vomiting. She was diagnosed with small bowel obstruction due to gallstone ileus. Diagnosis is usually challenging due to its nonspecific presentation, but computed tomography reveals the classic findings of Rigler’s triad -- pneumobilia, bowel obstruction, and an ectopic gallstone. The patient underwent laparoscopy with enterolithotomy with subsequent resolution of symptoms. Prompt diagnosis through imaging and timely surgical intervention is critical for in preventing complications and improving patient outcomes.

Clinical Implications Of Mismatch Repair Deficiency In Pancreatic Ductal Adenocarcinoma, Zachary Kaplan, Elizabeth Prezioso, Aditi Jain, Harish Lavu, Charles Yeo, Wilbur Bowne, Avinoam Nevler

Kimmel Cancer Center Faculty Papers

BACKGROUND: Pancreatic cancer is a highly aggressive and lethal disease, characterized by a limited response to chemotherapy and overall poor prognosis. Pancreatic cancers with a distinct mismatch repair deficiency, although relatively rare, have been shown to be associated with markedly better outcomes in comparison. Furthermore, whereas pancreatic cancers are generally unresponsive to current immunotherapy, this specific group of tumors has been shown to have a notable susceptibility to immune checkpoint inhibitors.

AIMS: In this review, we aim to summarize the relevant literature regarding mismatch-repair associated pancreatic cancers, the impacted biological mechanisms, and the resulting vulnerabilities for potential opportunistic immunotherapeutic treatment …

The Role Of Ucp2 In Pancreatic Cancer Metabolism And Its Potential As A Radiosensitizer, Emily Rieff

Dissertations and Theses (Open Access)

Uncoupling protein 2 (UCP2) is a mitochondrial protein that regulates the flow of protons down the gradient established by the electron transport chain (ETC) without generating ATP, thus uncoupling the proton gradient from ATP generation. In tumors, specifically pancreatic cancer (PDAC), the ETC is highly stimulated to generate the copious ATP needed by the tumor to grow. However, extended ETC use increases reactive oxygen species (ROS), and if left unchecked, results in cell death. To evade this, PDAC employs antioxidant strategies, including upregulating UCP2 in tumor cells. In addition to its uncoupling function, UCP2 indirectly controls ROS levels by maintaining …

The Role Of Myosin 5b In Intestinal Health And Disease: From Microvilli Assembly To Colorectal Cancer Progression, Sarah Aline Dooley

MUSC Theses and Dissertations

Background: Myosin Vb (Myo5b) is an essential molecular motor responsible for delivering diverse cargo to the apical membrane of enterocytes. Mutations in Myo5b cause congenital enteropathies, but its broader role in maintaining the integrity of the intestinal brush border under normal physiological conditions and in disease remain unclear. We hypothesize that Myo5b participates in the assembly and maintenance of the intestinal brush border by transporting members of the intermicrovillar adhesion complex (IMAC) and the xenobiotic efflux pump P-glycoprotein (P-gp) to the apical membrane of enterocytes. We further hypothesize that dysregulation of the myosin chaperone protein, UNC45A, and downregulation of Myo5b …

The Role Of Biological Sex In The Treatment Of Acute Cholecystitis, Desiree Duncan, Camden Gardner, Polina Chuikov, Matthew George, Sadaf Hashemian, Jeffrey Johnson, Md

Medical Student Research Symposium

Faculty, Staff and Students Publications

Background: Acute liver failure (ALF) is a loss of liver function due to a severe hepatic insult. Studies utilizing the azoxymethane (AOM) mouse model of ALF, which also generates hepatic encephalopathy, have primarily focused on development of neurological deficits. However, the molecular processes that generate liver damage have not been fully characterized. Therefore, a more comprehensive characterization of the hepatic consequences of AOM toxicity is needed to better understand this disease model.

Aim: To identify molecular pathology contributing to hepatic injury during the progression of AOM-induced ALF.

Methods: C57BL/6 mice were injected with AOM to produce ALF and hepatic encephalopathy. …

Nauli

Pharmacy Faculty Articles and Research

Chronic Hepatitis B Virus (HBV) infection remains a formidable global health challenge, driving severe liver complications such as hepatocellular carcinoma (HCC) and pyogenic liver abscesses (PLA). At the core of HBV persistence lies covalently closed circular DNA (cccDNA), a viral reservoir that fuels ongoing infection despite antiviral treatments. This review highlights molecular mechanisms governing cccDNA formation, maintenance, and clearance, spotlighting innovative therapeutic strategies to disrupt this key viral element. We explore cutting-edge approaches, including epigenetic modulation to silence cccDNA, RNA interference (RNAi) for viral RNA degradation, and CRISPR/Cas genome editing to excise cccDNA directly. Additionally, emerging antiviral therapies and immunotherapies, …

Department of Medicine Faculty Papers

Introduction: We present the first published case of turmeric-associated drug-induced liver injury (DILI) accompanied by significant ferritin elevation. Case Presentation: Our patient, a 59-year-old female with DILI caused by long-term ingestion of oral turmeric supplements, presented with painless jaundice on an annual exam. The patient’s liver function tests exhibited a hepatocellular pattern and hyperferritinemia (>2,000 ng/dL). Additional testing was negative except for heterozygosity for the H63D allele associated with hemochromatosis. A liver biopsy indicated acute hepatitis without fibrosis or stainable iron. Conclusion: Upon discontinuation of the supplement, liver enzymes normalized within a month. This case highlights the potential for …

Factors Driving Adolescent Tuberculosis Incidence By Age And Sex In 30 High-Tuberculosis Burden Countries: A Mathematical Modelling Study, Silvia S Chiang, Megan B Murray, Alexander W Kay, Peter J Dodd

Faculty, Staff and Students Publications

INTRODUCTION: During adolescence, tuberculosis incidence rises, with a greater increase in males compared with females. Tuberculosis notifications and estimates infrequently disaggregate adolescent age groups. Moreover, the factors that drive the increases in overall incidence and the male-to-female (MF) ratio remain unclear.

METHODS: We constructed a mechanistic model to estimate cumulative Mycobacterium tuberculosis infection and tuberculosis disease incidence in the WHO’s 30 high-tuberculosis burden countries (HBCs), which represent 86%–90% of global tuberculosis incidence. We derived infection risk from tuberculosis prevalence and assortative social mixing based on sex and age (10–14 years vs 15–19 years old). We adjusted age subgroup-specific risks of …

A Case Of Microscopic Colitis Masquerading As Chronic Inflammatory Diarrhea, Corey Haines, Sophia Moon, Giani Tah, Diana Acosta Pozo, Alejandro Aquino, Fatimah Bello

Research Symposium

Introduction: Microscopic colitis is an idiopathic, inflammatory form of colitis that is characterized by a normal macroscopic appearance of bowel but abnormal histological appearance on microscopy. Microscopic colitis can be subdivided into two histological subtypes: collagenous and lymphocytic. The collagenous subtype is characterized by proliferation of collagenous connective tissue that forms a thick subepithelial collagen band while the lymphocytic subtype is characterized by lymphocytic infiltrates and little to no proliferation of connective tissue. Classically, microscopic colitis presents with chronic, nonbloody, watery diarrhea lasting more than one month. It is typically associated with weight loss, abdominal pain, tenesmus, and nocturnal stools. …

INTRODUCTION: Global migration has increased in recent decades owing to war, conflict, persecution and natural disasters, but also secondary to increased opportunities related to work or study. Migrants' risk of tuberculosis (TB) differs depending on migration, socioeconomic status, mode of travel and TB risk in transit, TB incidence and healthcare provision in country of origin. Despite advances in TB care for migrants and new treatment strategies, decisions for managing migrants at risk of TB often rely on expert opinions, rather than clinical evidence.

METHODS: A systematic literature search was conducted, studies were mapped to different recommendation groups and included studies …
