Markey Cancer Center Faculty Publications

Eukaryotic elongation factor 2 kinase (eEF2K) is a stress-responsive regulator of protein synthesis implicated in melanoma progression, but its role in tumor immune evasion remains poorly defined. We investigated how eEF2K influences programmed death ligand 1 (PD-L1) expression through modulation of Cyclin D1. We analyzed gene expression and dependency datasets from The Cancer Genome Atlas and the Cancer Dependency Map. Protein–protein interactions were assessed by co-immunoprecipitation. Cyclin D1 was inhibited pharmacologically with palbociclib. Immune responses were evaluated in murine B16-OVA and human A2058 melanoma models using flow cytometry and immunohistochemistry after genetic or pharmacologic modulation of eEF2K and Cyclin D1. …

Population, Patient, Physician and Professionalism Projects

Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related death in the United States, with screening shown to significantly reduce mortality. However, incarcerated individuals experience substantially lower CRC screening rates and often present with more advanced disease than non-incarcerated individuals. Our project’s objective was to review the state of CRC screening in U.S. carceral settings, along with exploring possible alternatives to address the substantial disparity in CRC screening rates experienced by the incarcerated population.

North Texas GME Research Forum 2026

Background: Cellulitis is a common skin infection that classically presents with unilateral lower extremity erythema, swelling, and pain. The diagnosis is made clinically. Many conditions may mimic cellulitis that are collectively referred to as “pseudocellulitis.” These include stasis dermatitis, deep vein thrombosis, atopic dermatitis, psoriasis, and gout. The Alt-70 model is a validated clinical prediction tool for differentiating cellulitis from pseudocellulitis. It is unclear if it is utilized or if it has changed clinical practice in the emergency department setting.

Methods: This was a retrospective chart review study utilizing the HCA Healthcare Data Warehouse. The Alt-70 model was applied using …


Excision Followed By Standing Cone Deformity Repair Is Tissue Conservative, Henry Lim, Christian Scheufele, Marshall Hall, Stephen Weis, Dustin Wilkes Jan 2026

Excision Followed By Standing Cone Deformity Repair Is Tissue Conservative, Henry Lim, Christian Scheufele, Marshall Hall, Stephen Weis, Dustin Wilkes

North Texas GME Research Forum 2026

Introduction Elliptical excisions are the most common method to treat benign and malignant tumors in dermatologic surgery. This standardized design is traditionally 3 to 4.5 times longer than the excisional width to prevent unsightly protrusions of skin after primary closure, known as “standing cone,” “Burow’s triangles” or “dog ear” deformities. This results in a scar significantly longer than the original tumor that may be less easily concealed.

Objective To compare the final repair length of a tissue conservative method to remove skin tumors and close resultant defects against predicted repair length of traditional elliptical excision.

Methods Eighteen cases are presented …

Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiological features with Huntington’s disease (HD), a neurodegenerative disorder characterized by the expression of mutant huntingtin (mHTT) and marked dysfunction of cortico-striatal synapses and mitochondria. However, the role of SAPAP3 in mitochondrial function and HD pathophysiology remains unexplored. SAPAP3 was extracted from striatal synaptoneurosomes and analyzed by SWATH-MS proteomics to identify potential interactors, revealing SAPAP3 association with several mitochondrial proteins, particularly Mic60. These data were further complemented with proximity ligation …

Case Report: Suspected Rupture Of A Papillary Thyroid Tumor In A Patient With Graves' Disease Who Experienced Airway Narrowing Without Respiratory Distress., Daniel Goodman, Samuel Bosco, Bradford Davison Smith

Otolaryngology (ENT) Resident Research

This case report describes a 55-year-old woman presenting with acute dysphagia and neck swelling after a "popping" sensation in her neck. CT and MRI revealed a large retropharyngeal cystic mass and a left thyroid lobe mass, causing airway displacement. Despite significant effacement of the oropharyngeal and supraglottic airway on flexible nasopharyngolaryngoscopy, the patient remained asymptomatic regarding respiratory distress. Subsequent ultrasound-guided fine needle aspiration biopsy diagnosed malignant papillary thyroid carcinoma. Concurrently, previously undiagnosed Graves' disease was identified. The clinical presentation was attributed to suspected rupture or hemorrhage of the malignant thyroid tumor, leading to a serosanguineous fluid collection and inflammatory edema. …

Introducing Education For Sensory Approaches In Mental Health-Related Emergency Department Visits: A Quality Improvement Project To Enhance Patient-Centered Care, Jesse O'Neill

Master's Theses and Capstones

Background: Barriers to specialty care access have resulted in emergency departments (ED) operating as temporary psychiatric hold facilities for their communities. Patients boarding in the ED are demonstrated to use a disproportionate percentage of facility resources with minimal benefit to the patient. The Institute for Healthcare Improvement identifies the impact of the healthcare environment on patient outcomes and suggests staff training to foster trauma-informed practice culture (Schall et al., 2020).

Local Problem: High-stress healthcare environments can escalate maladaptive patient behaviors and the use of restrictive interventions. Traditional use of restrictive interventions lacks supportive evidence and contradicts person-centered care goals (Molloy …

Implementing A Standardized App-Led Multidisciplinary Medication Review And Reconciliation To Improve Medication Safety Before Systemic Cancer Therapy: An Ambulatory Oncology Quality Improvement Initiative, Sarah R. Hines

DNP Projects

Background

Adult patients initiating systemic cancer therapy frequently present with pre-existing polypharmacy related to chronic comorbidities and cancer-related symptom management. The addition of anticancer therapies and supportive care medications further increases medication burden and the risk of medication-related harm. Although national organizations and institutional policies recommend comprehensive medication review before treatment initiation, implementation remains inconsistent in ambulatory oncology practice.

Purpose

To implement and evaluate a standardized Advanced Practice Provider (APP)-led multidisciplinary medication review and reconciliation process designed to identify medication medication-related safety risks before initiation of systemic cancer therapy in adult oncology patients receiving care in an ambulatory infusion center. …


Improving Clinic Workflow To Enhance Rubeola Immunity Screening In Pregnant Patients, Courtney Mcduffie Jan 2026

Improving Clinic Workflow To Enhance Rubeola Immunity Screening In Pregnant Patients, Courtney Mcduffie

Doctor of Nursing Practice Final Project Abstract

Purpose: The purpose of this quality improvement (QI) project was to improve provider adherence to Rubeola IgG serum order entry for prenatal care visits by implementing a standardized workflow and an electronic medical record (EMR)-based order-entry process in a high-risk maternal outpatient clinic.

Background: Rubeola infection during pregnancy is associated with significant maternal and fetal complications. Despite recommendations from the American College of Obstetricians and Gynecologists (ACOG) to use serologic testing to determine immunity status, inconsistent provider ordering practices and workflow gaps contribute to missed opportunities for identifying non-immune patients and planning post-partum vaccination.

Methodology: A ten-week intervention period utilized …

The essentiality of protein in the human diet is unequivocal. Yet researchers, clinicians, and lay people often believe numerous propositions about dietary protein despite insufficient supporting or refuting data in some instances. To address this disconnect, and to "pressure-test" current beliefs about dietary protein, the Indiana University School of Public Health-Bloomington convened a workshop in February 2025 titled "Human Dietary Protein Needs and Benefits: A Critical Assessment of Postulated Propositions." More than 20 international experts discussed (1) methodologic issues affecting data acquisition and interpretation; (2) "optimal" dietary protein intakes and effects on muscle protein synthesis rates, muscle protein accretion, …

Children’s Nutrition Research Center Staff Publications

Background: The relationship between abdominal fat depots and cardiometabolic risk among youth is inconclusive due to the cross-sectional nature of existing studies and limitations in assessment methods. In this study, we examined cross-sectional and longitudinal associations of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) with cardiometabolic risk indicators among Mexican adolescents.

Methods: Participants (n = 169 at baseline and 134 at follow-up) were assessed for diastolic or systolic blood pressure (DBP or SBP), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, glucose, and insulin. VAT and SAT were measured using magnetic resonance imaging. Measures …


A Framework For Digital Energy Modulation And Translation In Projectional X-Ray Imaging, Richard R. Wargo Jan 2026

A Framework For Digital Energy Modulation And Translation In Projectional X-Ray Imaging, Richard R. Wargo

Theses and Dissertations

In projectional X-ray imaging, acquisition energy fundamentally influences subject contrast, image noise, and radiation dose. While dual-energy techniques exploit spectral differences to optimize contrast and enable material separation, acquiring multiple images of the same anatomy often requires additional exposures and increased system complexity.

This dissertation presents a framework for digital energy modulation (DEM), in which computational models are trained to translate projection images between energy domains without requiring additional X-ray acquisitions. DEM is conceived as a generalizable strategy for controlled contrast modulation in projection imaging, with potential applications in image optimization, radiation therapy alignment, and dual-energy applications.

The framework was …

Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease Incidentally Diagnosed During Post-Stroke Rehabilitation: A Case Report, Ching-Yun Liao, Chung-Hao Chao, Chih-Chin Hsu

Rehabilitation Practice and Science

背景

髓鞘少突膠質細胞糖蛋白抗體相關疾病(MOGAD)是一種罕見的自體免疫發炎性疾病,主要涉及中樞神經系統(CNS),其主要特徵是視神經、腦部和脊髓脫髓鞘。我們報告一例最初疑似復發性中風的病例,該病例在住院中風復健期間最終確診為MOGAD。

病例概要

49歲女性,左側大腦半球梗塞,在中風後復健期間出現多次右側肢體肌力下降伴隨失語症。這些神經功能波動偏離了典型卒中的預期復健軌跡。卒中發作兩個月後行腦部磁振造影(MRI)檢查,結果顯示右側內囊後肢、腦橋及C1脊髓出現多處新發病灶。後續血清學檢查顯示抗髓鞘少突膠質細胞糖蛋白(MOG)IgG抗體陽性,而水通道蛋白4(AQP4)抗體陰性,確診為MOGAD。患者接受了甲潑尼龍治療及充分的復健治療,追蹤期間肌力顯著改善,未見脫髓鞘病灶復發。

結論

本案例凸顯了復健科醫師在早期發現類似中風的神經發炎性疾病的關鍵作用。復健科醫師處於獨特的領先地位,能夠透過持續的功能監測識別「危險信號」;任何偏離預期復健路徑或無法解釋的神經功能波動都應促使醫生進行進一步檢查。早期識別此類非典型模式,並及時進行免疫治療和多學科康復,可以預防永久性功能衰退,並優化長期預後。

Department of Radiology Faculty Papers

BACKGROUND: Stroke leads to complex chronic structural and functional brain changes that specifically affect motor outcomes. The brain predicted age difference (PAD) has emerged as a sensitive biomarker of both sensorimotor and cognitive function after stroke. Our previous study showed a higher global brain PAD associated with poorer motor function after stroke. However, the association between local stroke lesion load, regional brain age, and motor impairment is unclear. This study aimed to investigate the associations between focal lesion damage, regional brain PAD in both hemispheres, and motor outcomes in chronic stroke, and to identify key predictors of motor impairment.

METHODS: …

Synthesis And Characterization Of Succinate Dehydrogenase Inhibitors H2/Z14 And C6/Z96 In Order To Combat Small Cell Lung Cancer, Lauren M. Graves Jan 2026

Synthesis And Characterization Of Succinate Dehydrogenase Inhibitors H2/Z14 And C6/Z96 In Order To Combat Small Cell Lung Cancer, Lauren M. Graves

Honors Undergraduate Theses

The use of ubiquinone inhibitors to combat cancer is a recent development in medicinal science and procedures to efficiently synthesize these drugs remain limited. C6/Z96 and H2/Z14, two succinate dehydrogenase inhibitors, have been previously tested in vitro against NSCLC with positive results. Their similarity to ubiquinone is what makes them a strong candidate for a succinate dehydrogenase inhibitor at the ubiquinone binding site. The heterocyclic scaffolds and substituents are proposed to bind strongly through a combination of electronics, hydrogen-bonding, and fit, allowing them to bind well and prove to be more favorable than ubiquinone when competing for the Q-site. By …

Dengue Fever With Normal Platelet Count In A Patient With Β-Thalassemia Trait: A Case Report., Pankaj Kumar Jain, Manoj Seval, Vikas Meena, Rajesh Kumar Yadav

Digital Journal of Clinical Medicine

Dengue fever is an arboviral infection caused by different serotypes of the dengue virus. Generally, it presents with a wide variety of symptoms ranging from undifferentiated fever to dengue shock syndrome associated with thrombocytopenia and hemoconcentration. But in patients with thalassemia, it presents with anemia due to hemolysis, rather than hemoconcentration. Here we present a case of an 18-year-old female diagnosed with Dengue fever with thalassemia trait, who presented with a normal platelet count and moderate microcytic anemia.


Limitations Of Plasma Exchange In Yellow Phosphorus-Induced Acute Liver Failure: A Case Report, Vihitha Vunnam, Swathi B.S Jan 2026

Limitations Of Plasma Exchange In Yellow Phosphorus-Induced Acute Liver Failure: A Case Report, Vihitha Vunnam, Swathi B.S

Digital Journal of Clinical Medicine

Yellow phosphorus is a highly toxic compound commonly used in rodenticides and is associated with significant morbidity and mortality following ingestion. Toxicity typically evolves through an initial gastrointestinal phase, a deceptive latent period, and a final phase characterized by fulminant hepatic failure and multiorgan dysfunction. We report the case of an 18-year-old male who intentionally ingested two tubes of Ratol containing 3% yellow phosphorus. After initial vomiting and transient clinical stability, he developed rapidly progressive acute liver failure with severe coagulopathy, conjugated hyperbilirubinemia, hepatic encephalopathy, acute pancreatitis, pancytopenia, acute kidney injury, metabolic derangements, and recurrent hypoglycemia. Serial laboratory trends demonstrated …


When Fever And Thrombocytopenia Are Not Infectious: A Case Of Vitamin B12 Deficiency Mimicking Tropical Fever, Ram Arvind Viswanathan Dr Jan 2026

When Fever And Thrombocytopenia Are Not Infectious: A Case Of Vitamin B12 Deficiency Mimicking Tropical Fever, Ram Arvind Viswanathan Dr

Digital Journal of Clinical Medicine

Vitamin B12 deficiency is classically associated with megaloblastic anaemia and neurological manifestations; however, atypical presentations continue to pose diagnostic challenges. Fever in association with thrombocytopenia often prompts evaluation for infectious aetiologies such as dengue, malaria, or sepsis, particularly in tropical settings. We report a case of vitamin B12 deficiency presenting with pyrexia and isolated thrombocytopenia, initially suspected to be an infectious illness. Extensive evaluation failed to reveal an infective cause, and subsequent haematological workup demonstrated megaloblastic changes with low serum vitamin B12 levels.
