The Devil In The Bakken, Kennedy Lorraine Delap

Graduate Student Theses, Dissertations, & Professional Papers

In 2008 the oil boom hit North Dakota. The oil brought wealth and human health concerns to the state and specifically, the Fort Berthold Indian Reservation. In July of 2024 the largest Clean Air Act Settlement of its kind happened on the reservation due to Marathon Oil emitting thousands of tons more pollutants that regulations outlined. This story dives into the human health effects, advocacy and the difficulty in balancing health and wealth on the reservation.

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

The Effects Of Plx 3397 On Fentanyl Escalation In Male And Female Sprague-Dawley Rats, Jakob Shaykin

Theses and Dissertations--Psychology

Purpose: A hallmark characteristic of opioid use disorder (OUD) is a persons’ ‘loss of control’, which leads to the compulsion to seek and obtain opioids, resulting in increased consumption. This phenomenon is known as ‘escalation of drug intake’. Chronic opioid use causes microglial reactivity and subsequent release of proinflammatory cytokines leading to neuroinflammation, weakening one’s executive control over drug taking and ultimately leading to greater use. Previous research in our laboratory has explored heterogeneity of fentanyl intake in extended access (6-hr) sessions and identified distinct endophenotypes of fentanyl intake. Moreover, we have observed a positive correlation between Treml1 expression …

Micro/Nanoplastics And Cancer: Focus On Gastrointestinal Malignancies - A Narrative Review, Sana Rabeeah, Priyata Dutta, Ahmad Mahdi, Alejandra Vargas, Edward C. Oldfield, David A. Johnson

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are plastic particles smaller than 5 mm and 1 μm, respectively, and are emerging environmental pollutants with growing implications for human health. These particles stem from either 'primary sources', such as intentionally manufactured microbeads and industrial abrasives, or 'secondary sources', where larger plastic items break down into smaller fragments over time. Human exposure primarily occurs through ingestion and inhalation, with contaminated seafood and plastic-laden food packaging representing key routes of entry. Once ingested, MNPs can cross the intestinal barrier, accumulate in gastrointestinal (GI) tissues, and trigger biological responses. Mechanistic studies reveal that MNPs induce oxidative stress, …

Drug-Induced Leukocytoclastic Vasculitis From An Unreported Source: Daptomycin, Jennifer K. Priessnitz, Timothy Kuzel, Lindsay Ackerman, Nelson Nicolasora

Department of Medicine Faculty Publications

Leukocytoclastic vasculitis (LCV) is a rare small-vessel vasculitis caused by immune-complex-mediated deposition on endothelial cells of dermal capillaries. Common triggers include medications, infections, autoimmune disorders, and malignancies. We present a case of a 58-year-old male who developed daptomycin-induced LCV after being treated for Methicillin-resistant Staphylococcus aureus (MRSA) endocarditis. The patient experienced painful palpable purpura on his lower extremities, which was diagnosed as LCV by skin biopsy. At the time of the biopsy, warfarin and daptomycin were discontinued, and the patient was transitioned to heparin and ceftaroline. MRSA-induced LCV was ruled out, due to negative blood cultures and adequate source control …

Treatment Of Myocardial Infiltration Of Hodgkins Lymphoma: A Catch-22, Jennifer Priessnitz, Erin Biringen, Fadi Khoury, Christina Bergin

Department of Medicine Faculty Publications

Background: Cardiac sequelae in Hodgkin Lymphoma (HL) can manifest as involvement of the heart and pericardium. Direct cardiac involvement is rare, and myocardial infiltration is distinctly unusual.¹ When it does occur, it is often a late manifestation of lymphoma, with a median onset of 20 months after initial diagnosis, and it is usually associated with advanced-stage disease.²

Case: A 34-year-old male was diagnosed with classic HL by lymph node biopsy. During his hospitalization, the patient remained in sinus tachycardia with heart rate up to 150 with no dysrhythmias. Transthoracic echocardiogram (TTE) revealed a reduced ejection fraction (EF) of 36% concerning …

Investigating Whether Txnrd2 Is A Therapeutic Target Against Triple Negative Breast Cancer Using African American-Derived Models, Keacha Chang

Dissertations

Despite similar breast cancer incidence rates, African American (AA) women experience a 40% higher mortality rate compared to Caucasian American (CA) women. This disparity is multifactorial and particularly pronounced in the Chicago area. AA women are twice as likely to be diagnosed with triple-negative breast cancer (TNBC), often at a younger age and with more aggressive disease. TNBC is a heterogeneous subtype lacking targeted therapies and is associated with the poorest prognosis among breast cancer types. Therefore, there is an urgent need for novel therapeutic strategies for TNBC, especially those tailored to AA patients. The thioredoxin pathway is essential for …

Forgoing Nuclear: Nuclear Power Plant Closures And Carbon Emissions In The United States, Luke Petach

Funded Scholarship

This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state-level carbon emissions and electricity generation from the Energy Information Administration (EIA), this paper adopts a difference-in differences (DiD) approach to estimate the effect of nuclear decommissioning. Two-way fixed-effects (TWFE) DiD estimates suggest a nuclear plant closure increases annual state-level per capita carbon emissions between 6% and 8%. The increase in state-level carbon emissions is driven by a substitution toward fossil fuel electricity—particularly …

Manuscripts, Articles, Book Chapters and Other Papers

Pediatric lead poisoning remains a persistent public health problem. Children in the US spend the preponderance of their time at home; thus, housing is an important social determinant of health. Improving health outcomes derived from housing-based sources involves differentiating the risks posed by the existing housing stock. In this paper, we developed a parcel-level lead risk index (LRI) based on external housing conditions and the year of home construction. The purpose of this study was to introduce a housing-based lead risk index (LRI), developed using retrospective data, to estimate parcel-by-parcel variation in housing-based lead risk. We described how the LRI …

Ccr5-Ligand Decorated Rilpivirine Lipid-Based Nanoparticles For Sustained Antiretroviral Responses, Milankumar Patel

Theses & Dissertations

Antiretroviral therapy (ART) is the standard remedy to improve the health-related quality of life of people living with human immunodeficiency virus (HIV). However, limited access to the viral reservoir has significantly hindered its effectiveness in fully eradicating HIV. Therefore, to improve HIV therapy, here we propose a C-C chemokine receptor type 5 (CCR5)-targeted theranostic lipid Based Nanoparticles (LBNPs) to noninvasively track and specifically deliver the antiretroviral drugs (ARVs) to the viral reservoir. A multi-modular radioactive nanoprobe was synthesized and co-encapsulated with rilpivirine (RPV, an ARV) into the LBNP to achieve a theranostic LBNP that can be tracked by positron emission …

Using Bivalves As An Indicator For Fecal Bacteria, Kamala Chuss

Honors Scholar Theses

This project focuses on the integration of fecal bacteria from warm-blooded animals into bivalve tissue, and the utilization of bivalves as an indicator for fecal bacteria in waterways. Bivalves may give a more representative long-term average of fecal bacteria in water as compared to direct water testing. The primary objective is to create a standard operating procedure to use bacterial testing of bivalves as a proxy for bacteria concentration in the water. This method can be used in places where bivalves do not already exist by adding them to a body of water, or by collecting bivalves that already exist …

Pediatric Flecainide Pharmacogenomics: A Roadmap To Delivering Precision-Based Care To Pediatrics Arrhythmias., Ronald Palmen, Mollie Walton, Jonathan B. Wagner

Manuscripts, Articles, Book Chapters and Other Papers

Flecainide acetate is a Class 1c anti-arrhythmic with a potent sodium voltage gated channel blockade which is utilized for the second-line treatment of tachyarrhythmias in children and adults. Given its narrow therapeutic index, the individualization of drug therapy is of utmost importance for clinicians. Despite efforts to improve anti-arrhythmic drug therapy, there remain knowledge gaps regarding the impact of variation in the genes relevant to flecainide's disposition and response. This variability is compounded in developing children whose drug disposition and response pathways may remain immature. The purpose of this comprehensive review is to outline flecainide's disposition and response pathways while …
