Antagonistic Effects Of Glucagon And Insulin On 5-Fluorouracil Efficacy In Colorectal Cancer, Gabriel M. Randolph, Andrea Florian

SPARK Symposium Presentations

Prior research on the combined effects of insulin and glucagon with low-dose chemotherapy in cancer treatment has yielded contradictory conclusions. Insulin potentiation therapy (IPT), a longstanding but understudied approach, is broadly claimed to enhance chemotherapeutic efficacy; however, it has also been characterized as pseudoscience lacking physiological merit. Adding further complexity, glucagon, insulin's antagonist hormone, has been shown to produce anti-cancer effects when combined with chemotherapeutic agents. The present study aims to observe the individual effects of both hormones on colorectal cancer cells in combination with 5-Fluorouracil (5-FU), to clarify their respective roles in combination therapy. Through the modulation of both …

From Fog To Function: An Occupational Therapist's Guide To Evaluating And Treating Cancer-Related Cognitive Impairments, Lauren E. Toner

Entry-Level Occupational Therapy Doctorate - Doctoral Capstone Symposium

Cancer – related cognitive impairment (CRCI) is a common side effect of cancer treatment that interferes with cancer survivors’ occupational performance, independence, and quality of life. Despite its high prevalence, CRCI remains under recognized and inconsistently addressed within oncology care. About 70% of individuals diagnosed with cancer report cognitive changes during or after treatment, yet many do not receive treatment. Occupational therapists are clinically trained to evaluate and treat functional cognition, activities of daily activities, instrumental activities of daily living, and client centered goals, positioning them as key providers in addressing CRCI. However, limited occupational therapy specific resources have hindered …

A Review Of Mobility And Gait Changes In Patients With Prostate Cancer: Disease Stage, Symptom, And Treatment-Related Influences, Lauren Hathorn, Abigail Schmitt Dr

2026 Honors Symposium

Background: This review examines the impact of prostate cancer symptoms, progression, and treatments on patients’ gait and mobility. Prostate cancer is the leading cancer diagnosis for men in the United States, with an increase in incidents in the last decade. Prostate cancer, its progression, and its various symptoms and treatments have both physical and functional consequences that often cause changes in patients’ mobility and gait. Some studies have found gait to be a predictor of functional decline and mortality. Given that functional decline and mortality are also consequences of cancer progression and cancer treatments, gait analysis could offer a non-invasive …

Department of Medical Oncology Faculty Papers

BACKGROUND: Genetic testing has become more complex with the transition from single gene testing to multi-gene panels and whole-exome sequencing. The adoption of more complex genetic testing and the promise of precision medicine has created a critical and urgent need for longitudinal clinical follow-up with patients who undergo cancer genetic testing given the residual uncertainty. There is an increasing need for multidisciplinary translational research that focuses on how to advance precision medicine discoveries into clinical practice and to capitalize on connectivity (e.g. digital health) interventions in ways that optimize cancer risk reducing behaviors in real-world clinical populations.

Yaddanapudi, M. Chadi Alraies, Said Ashraf, Jeffery Van Hook, Yegeny Brailovsky

Department of Medicine Faculty Papers

BACKGROUND: CHA2DS2-VASc score in cardiac amyloidosis (CA) with atrial fibrillation (AF) is believed to underestimate ischemic stroke risk, necessitating a better predictive model.

METHODS: Data were obtained from the National Readmission Database (NRD). Outcomes between CA-AF and no-CA-AF were compared using multivariate regression analysis to calculate adjusted odds ratios (aORs). AutoScore, an interpretable machine learning framework, was used to develop a stroke risk prediction model, and its predictive accuracy was evaluated with an area under the curve (AUC) using the receiver operating characteristic analysis.

RESULTS: A total of 11,860,804 (CA-AF 22,687 (0.19%) and no-CA-AF 11,838,117) patients were identified from 2015 …

Regulation Of Icer Degradation And Its Role In Melanoma, Justin Wheelan

Theses, Dissertations and Culminating Projects

Melanoma is the deadliest form of skin cancer, with 100,640 new cases and 8,290 deaths estimated in the United States in 2024. While targeted therapies and immunotherapy have improved patient outcomes, resistance remains a major challenge, necessitating new therapeutic approaches. Approximately 50% of melanomas harbor BRAFⱽ⁶⁰⁰ᴱ mutations, leading to constitutive MAPK pathway activation. Targeted small molecule therapies such as BRAF and MEK inhibitors are available and initially reduce tumor burden, however resistance frequently occurs, likely through many pathways including compensatory activation of cAMP signaling. ICER (Inducible cAMP Early Repressor), a transcriptional repressor of CREB-mediated gene expression, is absent in melanoma …

Effects Of Flavonoids On Reducing Colon Cancer Risk Via Macrophage Polarization, Gracien Jules

Graduate Theses and Dissertations

Colorectal cancer is one of the most fatal diseases in the United States. Chronic tissue inflammation can cause cell proliferation, which leads to tumor formation and cancer development. Macrophages are responsible for maintaining tissue homeostasis and for inflammatory responses. M1 macrophages exhibit proinflammatory responses while M2 macrophages exhibit anti-inflammatory responses. Imbalance between M1 and M2 macrophages is closely related to inflammation-associated disease development. The anti-inflammatory effects of apiaceous vegetable constituents, specifically flavonoids, have been studied for their preventative effects towards reducing disease risk. However, sufficient evidence is lacking on the mechanisms by which flavonoids impact M1/M2 macrophage polarization. RAW 264.7 …

Do Finances Determine Our Fate?: Understanding The Relationships Between Socioeconomic Status, Inflammation, And Cancer Recurrence Risk, Faith Wilbourne

Master's Theses

Individuals of a low socioeconomic status (SES) are more likely to experience a cancer recurrence relative to individuals with a higher SES. This may be partially explained by the stressors of living with a low SES. These stressors can increase inflammatory markers known to elevate the risk of cancer development. Health-promoting behaviors such as exercise, adequate sleep, and a healthy diet can reduce systemic inflammation. Health behaviors may therefore moderate any potential relationship between SES and cancer recurrence risk. This study explored associations between SES (income, educational attainment) and inflammatory markers related to cancer recurrence while seeking to determine if …

Case With Refractory Myasthenia Gravis Caused By Pembrolizumab, Khaled M. Darwesh, Bushra Amer, Lateefah D. Hawshab, Fatima D Hawshab

Journal of Community Hospital Internal Medicine Perspectives

Nowadays, checkpoint inhibitors play a major role in the management of different types of cancers. However, we have seen variants of immune therapy-related adverse events, which usually are variables from fatigue, to neuropathy to severe devastating complications such as respiratory failure due to myasthenia gravis (MG), as we saw in our case. Our patient was started on pembrolizumab, and they developed severe respiratory failure attributed to MG after three weeks from treatment initiation. Also, the patient presented with myositis, mild myocarditis and hepatitis, which were all related to pembrolizumab.

We sought to examine the national inpatient sample database to describe in-hospital outcomes among smokers with EOCRC. The NIS was searched for hospitalizations of adult patients with EOCRC, defined as all-cause colorectal cancer in patients 50 years old or younger. In this nationally representative population‐based retrospective cohort study, hyperlipidemia was associated with higher mortality.

Investigating Pinch-1 In Glioblastoma Multiforme: A Potential Adjuvant Therapy Target To Improve Treatment Outcomes, Saikrishna Gaddam, Dianne Langford

Rowan-Virtua Research Day

Gliomas account for approximately 80% of all brain cancers and 30% of central nervous system tumors. Glioblastoma multiforme (GBM), the most common, is unfortunately, the most aggressive glioma cancer type. Despite treatment efforts such as surgery, radiation, and chemotherapy, nearly all low-grade astrocytoma progress to GBM without complete surgical resection. Achieving full surgical removal is typically impossible, leading to an almost 100% recurrence rate of GBM after 9 months with a median survival of approximately 15 months. This poor prognosis is due to its high invasiveness and resistance to therapy. Therefore, improved therapeutic approaches are needed to reduce recurrence and …

Developing And Validating Brain Tumor Organoid Models To Evaluate Novel Therapeutics In Vitro, Dev P. Patel

Senior Theses

Glioblastoma (GBM), a World Health Organization Grade IV brain tumor, remains one of the most aggressive and treatment-resistant malignancies. It is characterized by rapid proliferation, deep infiltration, and a high level of genotypic and phenotypic heterogeneity. Despite advancements in medical technology and neuro-oncology, GBM remains one of the most treatment-resistant cancers with a median survival rate of only nine months post-diagnosis and less than 5% of patients surviving beyond 5 years of diagnosis. The standard treatment constitutes maximum surgical resection followed by chemotherapy and radiation. These therapeutic strategies are blocked by significant challenges like the blood-brain barrier (BBB), and intratumoral …

Alk Drives Neuroblastoma Tumorigenesis Via Upregulation Of Postn And Activation Of Wnt And Stat3 Signaling, Miller Huang, Wanqi Fang, Alvin Farrel, Linwei Li, Tania Porras Corredor, Shahab Asgharzadeh, John Maris, William A. Weiss

Research Symposium

Background: Neuroblastoma (NB) is the most common extracranial solid tumor in children. Two of the earliest known genetic drivers of NB are the oncogene MYCN and receptor tyrosine kinase ALK. While animal models show MYCN and mutationally active ALK F1174L can accelerate NB tumorigenesis, the mechanism of this cooperation is unknown. This study applied a human stem cell-based model to elucidate how ALK cooperates with MYCN to accelerate tumorigenesis of NB.

Methods: Induced pluripotent stem cells (iPSCs) were engineered with doxycycline-inducible MYCN and constitutively active ALKF1174L. These iPSCs were differentiated into trunk neural crest cells (tNCCs) and orthotopically transplanted into …

The Link Between Alcohol And Cancer: An Under Recognized Major Public Health Problem., Ihsan Salloum

Research Symposium

Objectives: Alcohol use related consequences is a worldwide major public health problem. Alcohol use is globally responsible for three million deaths each year and accounts for 5.1% of the global burden of disease. It accounts for the highest proportion of premature mortality among those ages between 15 and 49 years of age. Alcohol use has been linked to more than 200 disease and injury conditions and to poor health and disabilities of millions of people. While the link between alcohol and cancer has been recognized for a while, the awareness of such connection is still limited among the public …

Use Of Immunoglobulin Replacement Therapy In Clinical Practice: A Review, Jibran Ahmed, Yeonjoo Choi, Taeyeong Ko, Joann Lim, Joud Hajjar

Faculty, Staff and Students Publications

Immunoglobulins (Igs) are produced by B lymphocytes and play a key role in humoral immunity. Igs are classified into five isotypes (IgG, IgA, IgM, IgE, and IgD). Their primary function is to recognize and bind to foreign antigens. When Igs bind to antigens, they facilitate phagocytosis and promote clearance mediated by other immune cells. It is an essential component in protecting the host from outside pathogens. Hypogammaglobulinemia predisposes an individual to severe and recurrent infections. Therefore, replacement therapy is recommended to maintain optimal Ig level. In addition, Igs can modulate immune responses by to neutralizing proteins such as endotoxins or …

Advance Care Planning Utilization Among Non-White Individuals With Heart Disease And Cancer Using Health Retirement Study (Hrs) Data, Trizah M. Njoroge

Nursing Dissertations - Archive

Advance Care Planning (ACP) is a critical component of patient-centered care, yet its utilization remains disproportionately low among Non-White populations in the United States, particularly among individuals with chronic illnesses such as heart disease and cancer. This article explores racial disparities in ACP engagement using secondary analysis of the 2018 and 2020 waves data from the Health and Retirement Study (HRS), guided by Bandura’s self-efficacy theory (SET). The study examines how race, disease type, comorbidity, and survey year predict ACP service utilization, defined as completing five key ACP components: a legal will, a medical care discussion, surrogate assignment (DPOA), a …

3d Bioprinting Technology Innovation In Female Reproductive System, Siyao Chen, Tongxin Wang, Jiaqi Chen, Mingxing Sui, Luyao Wang, Xueyu Zhao, Jianqiao Sun, Yingli Lu

Department of Obstetrics & Gynecology Faculty Publications

Several diseases affect the female reproductive system, and both disease factors and treatments impact its integrity and function. Consequently, understanding the mechanisms of disease occurrence and exploring treatment methods are key research focuses in obstetrics and gynecology. However, constructing accurate disease models requires a microenvironment closely resembling the human body, and current animal models and 2D in vitro cell models fall short in this regard. Thus, innovative in vitro female reproductive system models are urgently needed. Additionally, female reproductive system diseases often cause tissue loss, yet effective tissue repair and regeneration have long been a bottleneck in the medical field. …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

Characterizing A Rad23 Dependent Ultraviolet Radiation Resistance In Tetrahymena Thermophila, Emma June Liimatta

Graduate Theses/Dissertations

In 2020, 10 million deaths were attributed to cancer, with multidrug resistance being responsible for over 90% of deaths in cancer patients receiving treatment. This study utilized the model organism Tetrahymena thermophila to study how cells become resistant to Ultraviolet Radiation (UV) radiation, a process similar to multidrug resistance, specifically focusing on the nucleotide excision repair and ubiquitin shuttle protein Rad23. The National Cancer Institute documented 30-60% of cancers tested had a mutation in RAD23. Knockdown of RAD23 in Tetrahymena thermophila demonstrated a UV resistance phenotype with decreased nucleotide excision repair and differential expression of proteins active within caspase-independent …
