Metastatic Large Cell Neuroendocrine Carcinoma: A Rare Cause Of Hypopituitarism, Smriti Nair, Taskeen Ahmed, Jessica Watari

Division of Internal Medicine Faculty Papers & Presentations

Pituitary metastases from pulmonary large cell neuroendocrine carcinoma (LCNEC) are exceedingly rare but should be considered in patients presenting with arginine vasopressin deficiency and panhypopituitarism in the context of known or suspected metastatic lung cancer. Early recognition and prompt initiation of hormonal replacement therapy are essential to prevent life-threatening endocrine crises and to improve symptom burden. We describe a case of a 43-year-old male who presented with dyspnea, weight loss, and weakness who was found to have metastatic LCNEC involving the liver. Endocrine evaluation revealed central hypothyroidism, central adrenal insufficiency, and later arginine vasopressin deficiency manifested by polyuria and hypernatremia. …

We utilized descriptive statistics, intra-rater reliability tests, and mixed-effects ordinal regression to analyze divergence …

Slc Transporter-Mediated Functional Imaging In Cancer Diagnosis, Lumeng Zhang, Jun He

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Functional imaging has become an important approach for evaluating tumor physiology in vivo beyond morphologic assessment. Radiotracers used for cancer imaging are designed to mimic endogenous substrates or substrate analogues, and their accumulation can depend on membrane transport, intracellular metabolism, and clearance from normal tissues. Specifically, SLC transporters contribute to tracer uptake and signal formation, linking transporter activity with measurable imaging signals in cancer. While [18F]FDG PET/CT remains the most widely used example of transporter-associated metabolic imaging, SLC transporter-mediated imaging strategies have been developed to assess amino acid transport, sodium-dependent glucose uptake, redox metabolism, lactate exchange, nucleoside metabolism, choline metabolism, …

Makara Journal of Science

Early and accurate diagnosis for spinal muscular atrophy (SMA) has gained relevance in an era of emerging therapies to improve patient outcomes. While screening of dried blood spots (DBS) effectively detects deletion-type SMA, non-deletion cases are often missed. Mutation screening from DBS is needed to address this gap. Here, we aimed to evaluate the feasibility of an in-house, cellulose-based card for direct Sanger sequencing for variant hunting, avoiding DNA extraction and offering an alternative to commercial cards. As a proof of concept, sequences obtained from DBSs of 23 healthy individuals were compared with sequences derived from isolated genomic DNA (gDNA). …

Peripheral quantitative computed tomography (pQCT) is a widely used imaging technique for assessing volumetric bone mineral density (vBMD) in pediatric populations; however, conventional methods may obscure subtle cortical adaptations. The primary aim of this study was to evaluate the feasibility of shape-based cortical vBMD profiling, with an exploratory objective of assessing its sensitivity to inter-individual variation in lean mass index (LMI). Methods: Eighteen children (6–12 years) underwent pQCT scanning at the 38% and 66% tibial sites (distal and proximal diaphysis). Cortical vBMD was quantified across three …

Bridging Data Gaps In Retinal Imaging: From Structural Domain Adaptation To Topology-Aware Synthesis, Gözde Merve Demirci

Dissertations, Theses, and Capstone Projects

Comprehensive visualization of the retina is essential for diagnosing and monitoring blinding diseases such as Diabetic Retinopathy and Retinopathy of Prematurity (ROP), where pathological changes often extend beyond a single field of view. Despite significant advances in automated retinal image analysis, clinical deployment remains limited by two fundamental data gaps: a structural learning gap, arising from scarce expert annotations and poor generalization across imaging domains, and a spatial coverage gap, caused by the difficulty of acquiring multi-view retinal images in fragile populations. Although these challenges are often addressed independently, this dissertation argues that they are tightly coupled: accurate, …

Chikungunya, a debilitating mosquito-borne disease caused by chikungunya virus, has surged dramatically in the past two decades. Chikungunya outbreaks can intensify rapidly, with infections posing a significant endemic health burden in tropical/subtropical areas and for travelers. Health professionals require timely and accurate outbreak information to adequately protect travelers and assess chikungunya risk. However, detection is often insufficient in the areas most susceptible to outbreaks, leading to diagnostic and reporting delays. Consequently, travelers are often unaware of increased chikungunya infection risk at their destination. We assessed chikungunya surveillance and reporting resources, and we developed expert recommendations for traveler health protection. Because …

A History Of Native Medical Auxiliaries, Tanzania:1920s To The 1960s, Irene Gabriel Ndosi, Ashura Jackson Ngoya

Journal of Humanities and Social Sciences

This paper examines the role and evolution of Native Medical Auxiliaries (NMAs) in Kilimanjaro, Tanzania, during British colonial rule between the 1920s and 1960s. It argues that NMAs were not merely subordinates within the colonial medical system but active agents who negotiated and blended Western medical practices with indigenous healing knowledge. Drawing on archival records and oral histories, the paper finds that NMAs filled critical gaps in healthcare delivery, particularly in rural areas, while simultaneously preserving local therapeutic traditions. By applying Local Agency Theory, the paper highlights the NMAs’ strategic engagement with colonial structures and their contribution to shaping hybrid …

Stroke Mimics And Stroke Chameleons: Leveraging The False Positive/False Negative Diagnostic Schema In Resident Teaching, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background

Stroke mimics and stroke chameleons contribute significantly to diagnostic uncertainty in Emergency Medicine. Traditional teaching often relies on enumerating examples, yet residents struggle to internalize these distinctions.

Objective

To present a conceptual teaching framework that maps stroke mimics to false positives and stroke chameleons to false negatives, leveraging pre-existing diagnostic schemas.

Methods

Using representative cases—including hypoglycemic hemiparesis and spinal epidural lipomatosis presenting as stroke mimic—we developed an explanation for residents involving framing mimics as false positives and chameleons as false negatives.

Results

Framing mimics as false positives and chameleons as false negatives activates existing learner schemas related to sensitivity …

Point-Of-Care Intestinal Ultrasound Is Associated With Reduced Colonoscopy Utilization And Improved Clinical Decision-Making In Ibd, Lakumi Dias, Ashlyn Mcclelland, Amy Glasofer, Charalampos Papachristou, Yecheskel Schneider, Sanket Patel

Rowan-Virtua Research Day

Background:

Point-of-care intestinal ultrasound (IUS) enables real-time assessment of bowel inflammation, and it is underutilized in the United States. IUS provides visualization of bowel wall thickness, vascularity, and complications without radiation or bowel preparation. Prior studies demonstrate that IUS changes management and reduces reliance on invasive testing. This study hypothesizes that IUS will impact downstream clinical decision-making in a U.S. outpatient IBD cohort by decreasing invasive procedures and supporting appropriate treatment decisions.

Methods:

A retrospective cohort study was performed. Logistic regression and chi-square tests assessed associations between IUS use, colonoscopy referral, hospital utilization, and treatment modification. A derived “surveillance-due” variable …

The Case For Intraprocedural Ultrasound Guidance In Lumbar Puncture--From Landmarking To Navigation In Lumbar Puncture. A Conceptual Review And Research Agenda, James Espinosa, Frank Wheeler, Robin Lahr, Sergey Medlenov, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Ultrasound guidance for lumbar puncture (LP) is well established for pre-procedural landmark identification, particularly in patients with difficult anatomy. However, most current approaches discontinue ultrasound prior to needle insertion, returning the operator to a blind technique. Current emergency medicine ultrasound guided intravenous line insertion demonstrate feasibility of real-time needle visualization.  However,  the development and adoption of real-time guidance in the setting of lumbar puncture remains limited. Prior simulation work demonstrated that ergonomics, operator experience, and workflow integration significantly influence performance in ultrasound-assisted LP (Horn, Espinosa et al., 2016).  Here we make the case that LP is not a static targeting …

Rowan-Virtua Research Day

Title: Evaluating the 4mm Endometrial Thickness Threshold: Racial Disparities in Ultrasound Sensitivity and Diagnostic Delay

Background: Current ACOG guidelines utilize a 4mm endometrial thickness (ET) threshold via transvaginal ultrasound (TVUS) to exclude malignancy in postmenopausal women. However, recent evidence suggests these standardized thresholds may not be equally effective across all racial cohorts. This systematic review evaluates the diagnostic performance of the 4mm threshold specifically in Black patients.

Methods: A systematic search of peer-reviewed literature was conducted to identify studies comparing TVUS sensitivity and clinical outcomes between racial groups. Data were extracted focusing on the diagnostic sensitivity of the 4mm threshold, …

In low- and middle-income countries (LMICs), cardiovascular diseases (CVDs) are prevalent and pose a major concern as the current healthcare systems are oriented primarily towards communicable diseases. The largest contributor to CVDs, hypertension, is a significant issue in Kenya, a model LMIC. Based on previous studies in this lab, high rates of hypertension are present in the region of Kasigau, Kenya. Kasigau is a small region within Taita-Taveta County, Kenya. Traditional risk factors are not necessarily predictive of hypertension in all regions of Kenya. This study aims to address the lack of tested risk factors for hypertension in Kenya and …

Characterization Of Circulating Extracellular Proteome In Plasma Samples Of Triple-Negative Breast Cancer Patients, Brionna Wilson

Honors Theses

Extracellular vesicles (EVs) are membrane-bound vesicles secreted by cells in the body that play an important role in intercellular signaling, immune modulation, and transfer of biomolecules between cells. EV s reflect the physiological state of their cells of origin, so they are being explored as potential noninvasive biomarkers for cancer detection and monitoring. Triple-negative breast cancer (TNBC), an aggressive subtype lacking targeted therapies, is difficult to detect early and currently has no reliable prognostic biomarkers. This study aimed to quantify EV concentrations in the blood serum of TNBC patients (n=40) compared with cancer-free healthy controls (n=35) as well as determine …

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

Sepsis As An Immune Continuum: Cytokine Storm To Lymphopenia And Pics, Chelsey King

Senior Honors Theses

Sepsis is a leading cause of morbidity and mortality worldwide, driven by a dynamic immune continuum that progresses from early hyperinflammation to profound immunosuppression. This review examines the three overlapping phases of sepsis: the inflammation-mediated cytokine storm driven by dysregulated PRR activation, NF-κB signaling, and NETosis; apoptosis-driven lymphopenia involving caspase-mediated lymphocyte death, dendritic cell dysfunction, and metabolic exhaustion; and prolonged immunoparalysis culminating in persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Key mechanisms linking these phases, including the co-existence of hyper- and hypo-inflammatory states, are synthesized alongside relevant clinical biomarkers such as IL-6, HLA-DR, and single-cell immune profiles. This review highlights …

Honors Theses

Alzheimer's disease (AD) is a growing global health concern, with millions of people affected worldwide and cases expected to rise significantly in the coming decades. Early detection is critical for patient treatment and care, and recent advances in natural language processing (NLP) have shown promise in identifying linguistic markers associated with AD. However, most existing work has focused on English, leaving speakers of other languages with limited access to such tools. This study investigates how effective AD detection models trained on English data are at transferring to Greek, a low-resource language with limited dementia-related speech data available. We propose a …

Organic Synthesis Of A Hydrazine Functionalized Ammonium Compound For Improved Capture Of Aldehyde Metabolites From Exhaled Breath, Po'iu N. Burgo

Undergraduate Theses

Breath analysis has emerged as a non-invasive and inexpensive way to screen for respiratory diseases. This technique involves measuring concentrations of specific metabolites found in exhaled breath that serve as a biomarkers for disease. A subclass of volatile organic compounds called α,β-Unsaturated aldehydes, products of the lipid peroxidation mechanism, are underrepresented as biomarkers of lung cancer. These have been found to have relatively increased concentrations in the exhaled breath of lung cancer patients compared to a healthy patient. One of the reasons that these metabolites have been underreported is that the techniques used to measure and characterized exhaled metabolites do …
