Acute Respiratory And Renal Failure Following Delayed Recognition Of T-Cell Lymphoblastic Leukemia In A Previously Healthy Child, Olivia R. Kaufman, Christopher M. Ahmad, Samira Haberman, Ethan Speer, Curtis King

Student Publications

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive pediatric hematologic malignancy that frequently presents with mediastinal involvement. Delayed recognition can result in rapid clinical deterioration due to airway compression, metabolic derangements, and treatment-related complications. We report the case of a previously healthy 12-year-old male who developed acute hypoxemic respiratory failure secondary to a large mediastinal mass initially treated as pneumonia, in whom imaging demonstrated a large anterior mediastinal mass with airway compression and a malignant right-sided pleural effusion with the diagnosis of T-ALL. The hospital course was complicated by severe tumor lysis syndrome resulting in oligo-anuric acute kidney injury, recurrent …

Connected Pastors: The Importance Of Having Safe Support Systems In Ministry, Karin A. Hines

Senior Honors Theses

Pastors minister to broken people, but sometimes they need help themselves. Many pastors do not seek help or do not have anyone safe to go to, often for fear of losing their influence or job. This thesis argues that sharing one’s life with safe people is essential, especially for those who are in high-stress professions. It explores pastoral support systems, examines comparable stigmas against seeking help in other fields, analyzes the science of sharing and isolation and their effects on the brain and body, and considers the Bible’s instructions on living in community for one’s personal well-being. Pastors require intentional, …

Faculty, Staff and Student Publications

Introduction: Early open fracture management aims to minimise the risk of complications. For the most severe open fracture wounds, multiple irrigation and debridement surgeries are required to overcome severe wound contamination, to reassess the evolving tissue injury or to temporise and plan further surgery. When multiple irrigation and debridement surgeries are needed, uncertainty remains about how the open fracture wound should be managed to best minimise complications. The primary aim of this trial is to compare the antibiotic cement bead pouch vs negative pressure wound therapy in the management of patients with severe open tibia fracture wounds.

Hlafreq: Download And Combine Hla Allele Frequency Data, David A. Wells, Michael Mcauley

Research Outputs: 2025-Present

Human leukocyte antigen (HLA) genes encode cell-surface proteins which play an important role in immunity. Since different HLA alleles enable different immune responses, the population frequency of HLA alleles is often considered when designing vaccines (Gulukota & DeLisi, 1996). Specific HLA alleles have been linked to autoimmune disease (Simmonds & Gough, 2007) and associated with adverse drug reactions (Fan et al., 2017). Further, the success of solid organ and stem cell transplants is related to HLA matching between donor and recipient (Fürst et al., 2019; Morishima et al., 2002). We present HLAfreq, a Python package which can be used to …

Annona Muricata (Soursop) And Hematopoiesis: Ethnomedicinal Insights, Immunomodulatory Mechanisms, And Translational Challenges, Fatma Matano, Amiya Patra

Peninsula Medical School

Annona muricata (soursop) is a tropical medicinal plant widely used in traditional medicine across Africa, the Caribbean, and parts of South America. While its ethnomedicinal applications span a range of conditions, including infections, inflammation, and anemia-related symptoms, its potential relevance to hematopoiesis has not been systematically examined. This narrative review synthesizes ethnomedicinal knowledge, phytochemical composition, and experimental evidence to explore the biological plausibility by which A. muricata may indirectly influence hematopoietic processes. Bioactive constituents of A. muricata, including flavonoids, polyphenols, and acetogenins, have demonstrated antioxidant, anti-inflammatory, and immunomodulatory properties in preclinical models. These effects are particularly relevant given the established …

The Bonds Of Family: A Case Study On Interconnectedness In The Prison-Industrial Complex, Cameron Stone

Binghamton University Undergraduate Journal

Beginning in the 1960s, a rightward shift in politics and “War on Drugs” policies propelled the United States toward mass incarceration. The result was a prison population of around 2 million people, in which minority groups have been disproportionately imprisoned. While historians and legal scholars have examined the policies and legal structures behind mass incarceration, oral historians working in the tradition of social history emphasize the importance of narratives of those most impacted yet traditionally neglected. This paper specifically examines the relatively unstudied Columbia University's 2019 Mass Incarceration oral history collection, which explores the interconnected perspectives of one family’s experience …

Late Hepatitis B Reactivation After Hsct And B-Cell Depleting Therapy: Case Vignettes Challenging Fixed-Duration Prophylaxis, Ariana Cho, Harrison Moses, Muaz Alchirazi, Vishakh Keri, Lea Monday

Conference Presentation Abstracts

Hepatitis B virus (HBV) reactivation remains a critical concern in immunosuppressed oncology and hematopoietic stem cell transplant (HSCT) patients, yet the optimal duration of antiviral prophylaxis is unresolved. Current guidelines recommend 12–18 months of prophylaxis after HSCT or B-cell depleting therapy for patients who are isolated anti-HBc positive, based on documented cases of late reactivation beyond the traditional 12-month threshold. However, these recommendations largely derive from studies in HBsAg-positive patients or those receiving rituximab-containing regimens, with limited data addressing the broader range of high-risk scenarios encountered in practice. We present two vignettes highlighting this gap. Patient 1 is a 60-year-old …

Mycobacterium Chimaera In A Young Patient Without Underlying Cardiac Surgery History, Kate A. Szczesniak, Rakesh Shah, Malitha Hettiarachchi

Conference Presentation Abstracts

Introduction/Objective Mycobacterium chimaera (M. chimaera), within the Mycobacterium Avium Complex (MAC), is a slow-growing nontuberculous mycobacterium (NTM) species that is most often characterized by nonspecific symptoms of night sweats, fever, and fatigue. Due to the nonspecific symptoms of M. chimaera and the rarity of this infection, delayed or misdiagnosis occurs in these patients. Risk factors of contaminated heater-cooler units used in cardiac surgery have been reported; however, cases without this exposure, such as this case, have been cited less commonly. This case of M. chimaera will present a young patient initially presenting with dyspnea who was found to have a …

An Investigation Of Entamoeba Histolytica Chitin Synthases And Other Encystation Factors In Early Encystation, John N. Talledo

All Theses

Entamoeba histolytica is a food-and-water-borne human protozoan pathogen that relies on a two-stage life cycle for successful proliferation outside of the host. E. histolytica exists in its dormant cyst form while outside of its host and converts to the motile trophozoite (amoeba) form in the small intestine. The trophozoites colonize the large intestine to cause symptomatic disease in ~10% of infections, resulting in ~100 million cases of amoebic dysentery each year. Trophozoites can convert back to the cyst form, which is shed in feces to continue the infection cycle.

Currently, there is a lack of understanding of the exact molecular …

Testing The In Vitro Effectiveness Of Protease Inhibitors Against Histomonas Meleagridis, Evy Belle Hafer

Animal Science Undergraduate Honors Theses

Histomonas meleagridis is a protozoal parasite able to exist in a flagellated or amoeboid form that infects gallinaceous birds, particularly turkeys, and causes significant mortality. There is currently no effective treatment for this disease. The purpose of this study was to assess the anti-histomonal activity of commercially available protease inhibitors, leupeptin, bestatin, and antipain, using an established in vitro model. Three protease inhibitors, leupeptin, bestatin, and antipain, were evaluated across five assays. Treatment groups included: 1) non-treated control, 2) leupeptin 100 µM, 3) bestatin hydrochloride 100 µM, and 4) antipain dihydrochloride 100 µM.

The Effects Of Avian Influenza On Consumer Egg Prices In The United States, Jacob B. Franklin

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Outbreaks of highly pathogenic avian influenza (HPAI) create major challenges to poultry supply chains due to the high mortality rates in flocks, leading to disruptions in production and higher costs for producers. Using quantitative data from Federal Reserve Bank of St. Louis, USDA, and National Agricultural Statistics Service, this research analyzes changes in egg production, retail prices, and regional variations throughout the United States for the 2022-2025 HPAI event. A time-series regression model was used to control for production costs, seasonal patterns, and regional differences. All of these measures come together to quantify the impact of HPAI outbreaks on consumer …

Structure Of The Spoiie Protein In Clostridioides Difficile, Robert B. Bauer

Biological Sciences Undergraduate Honors Theses

Clostridioides difficile is an opportunistic pathogen responsible for severe gastrointestinal infection. C. difficile-related infection is extremely prevalent in healthcare facilities, causing roughly 30,000 deaths annually in the United States alone. Its main mechanism of virulence is sporulation, which is directed by the SpoIIE protein. This makes SpoIIE an attractive target for the remedy and prevention of infections. The objective of this study was to analyze its structure using both lab techniques and artificial intelligence modeling. A truncated version of this protein, SpoII∆TM, was expressed and analyzed using optimal conditions previously determined in the lab. SDS-PAGE results and analyses confirmed …

Efficacy Of Tick Sampling Methods In Urban Parks., Emma Staples

College of Arts & Sciences Senior Theses

Amblyomma americanum (Lone star ticks) are parasites and vectors of diseases, including Ehrlichiosis. Questions remain about how an urban environment affects the host-seeking behavior of A. americanum across different life stages and thus the efficacy of different sampling methods. We sought to compare the efficacy of different sampling methods on A. americanum ticks in urban parks during the fall season and explore how the urban heat island (UHI) effect may impact each method’s efficacy. We hypothesized that, where the UHI effect is weaker near the city’s periphery, the CO₂ trapping method would collect more A. americanum adults and nymphs …

Understanding Barriers To Breast Cancer Screening Among Rural Women In South Carolina: A Qualitative Study Using The Idea Model, Israt Jahan

All Theses

Breast cancer screening rates remain low among rural women in South Carolina, leading to higher incidences of late-stage cancer diagnosis. This qualitative study used semi-structured interviews to investigate reasons why many women delay or avoid screenings, even when free screening programs such as the Best Chance Network are available in South Carolina. Guided by the IDEA model, the study explored how women interpret cancer risk, how they seek and trust cancer information, how they understand screening explanations, and what barriers affect their ability to take action. Participants described fear of pain, fear of diagnosis, personal relevance, confusion about the screening …
