The State Of Oral Health In People With Disabilities And The Impact Of Family-Centered Care On The Oral Health Of Children With Special Health Care Needs, Bedant Chakraborty

Theses & Dissertations

Oral diseases are one of the most prevalent non-communicable, chronic diseases of the 21st century. Yet, dental diseases are generally neglected and are a top concern for policymakers globally. The burden of oral diseases disrupts routine activities that affect the overall quality of life, especially for those with special healthcare needs. Dental diseases have also been marked as the “silent epidemic” and are the leading secondary health condition that affects individuals with disabilities. Disabled people are less likely to receive timely and adequate dental care, which could be tied to poor oral health outcomes among them. This group of studies …

Crispr Technology As An Antiviral In Dsdna And Ssrna Viruses, Cathryn Mayes

Theses & Dissertations

The COVID-19 pandemic highlights the necessity of emergency response and pandemic preparedness, especially for emerging viral threats. Currently, virus-specific vaccines and antivirals are the primary tools to combat viral diseases; however, broad-spectrum antivirals that target more than one virus species could provide additional protection from emerging and re-emerging viral diseases (Andersen et al. 2020; Zhu et al. 2015; Hickman et al. 2022).

Clustered regulatory interspaced short palindromic repeat (CRISPR)-associated endonucleases have become recently utilized as potential antiviral strategies due to their high specificity, efficacy, and versatility (Najafi et al. 2022). While CRISPR-based antivirals have previously been used to target specific …

Understanding The Perceived Risk And Biopsychosocial Impact Of The Covid-19 Pandemic On People Living With Hiv And Pre-Exposure Prophylaxis Users In Nebraska: A Mixed Methods Approach, Titilola O. Labisi

Theses & Dissertations

The COVID-19 pandemic disrupted HIV care and prevention services. COVID-19 guidelines required physical and social distancing, resulting in movement restrictions and limited healthcare services. People living with HIV (PLWH) may be more vulnerable to the pandemic’s impact due to immune suppression and socioeconomic status than people without HIV. Consistent use of pre-exposure prophylaxis (PrEP), condoms, and regular sexually transmitted infection tests are critical strategies for HIV prevention. The pandemic’s impact on PLWH have not been thoroughly studied, and whether PLWH may be more impacted than PrEP users is inconclusive.

This research aimed to use an explanatory sequential mixed methods design …

Hepatocyte-Hepatic Stellate Cell Axis In Potentiation Of Alcohol And Hiv-Induced Liver Injury, Moses O. New-Aaron

Theses & Dissertations

Human Immunodeficiency Virus (HIV) remains a global threat, with approximately 38.4 million active infections and 33 million HIV-related deaths since the first case. While many may be tempted to think of HIV as a relic of the past, emerging data suggests otherwise. By the end of 2021, approximately 1.5 million HIV incidences and 650 000 mortalities were reported globally. The etiologies of HIV-related mortality are numerous. Liver disease is one of the leading etiologies of HIV-related mortality, especially in recent times of antiretroviral therapy (ART)-induced longevity among people living with HIV (PLWH). While co-infections with hepatotropic viruses notoriously contribute to …

Grip Characterization Of Protective Gloves, Doris Burns

Theses & Dissertations

In 2014, ASTM International (ASTM), one of the world's largest international standards developing organizations, published a new test method on glove grip performance. This method was adopted by the National Fire Protection Association (NFPA) in some of their specification standards. The method utilized hand torque instead of the pull method previously used by the NFPA to determine the Percent Bare Hand Control Value (%BHCV). The %BHCV, compares torque results of a gloved hand versus a bare hand. In developing this new test method, only four males and one female participated; therefore, it is unclear if statistical significance was attained. In …

The Link Between Fat Soluble Vitamin Deficiencies, Decreased Microbiota Diversity And Severity In Children With Sickle Cell Disease Followed In A Clinic In Omaha Nebraska, Chinenye R. Dike

Theses & Dissertations

Fat soluble vitamin (FSV) deficiencies are associated with worse pain in individuals with sickle cell disease (SCD). Data on the dietary and pancreatic function influence on fat soluble vitamin levels are limited. Additionally, individuals with SCD have gut dysbiosis but there are gaps in knowledge on the impact of this on severity. This thesis attempted to evaluate FSV prevalence and gut microbial profile in our cohort of children with SCD and compare this with matched healthy children and to ascertain if diet or pancreatic function affects these levels and see if these affects sickle cell severity.

Essential Protections For Essential Workers: Ethical Considerations For Infection Prevention And Control, Abigail E. Lowe

Theses & Dissertations

Prior to the COVID-19 pandemic, ethical guidance for workers during epidemics and pandemics centered on healthcare workers, which meant there was not guidance to address critical contextual issues for many on the frontlines of the pandemic. Meat processing workers are a key example of workers deemed essential during the COVID-19 pandemic and facing conditions of elevated risk without adequate public health guidance or resources to control disease spread. Meat processing workers are an underserved, resource-limited, and vulnerable workforce that face occupational health and safety risks. Meat processing and other essential workers have heightened health disparities due to the social determinants …

Gender Differences In Breast Cancer Treatment Decisions And Related Survival: A Study Using The National Cancer Database, Shamim Shahi

Theses & Dissertations

Despite increasing incidence, male breast cancer (MBC) remains understudied in almost all aspects of disease management. MBC patients are more likely to be diagnosed with larger tumors, at an advanced stage, and to experience poorer survival than female patients. There is a need to identify modifiable factors that can improve MBC patients’ survival.

This dissertation aimed to investigate whether there was a difference in the refusal of recommended treatments and related survival, by gender, in breast cancer patients enrolled in the National Cancer Database. Specifically, we conducted separate analyses for four treatments: hormone therapy, chemotherapy, radiation therapy, and surgery. Then, …

Frailty Determination And Responsiveness In Left Ventricular Assist Devices, Sarah Schroeder

Theses & Dissertations

Frailty, the state of being vulnerable with susceptibility to decreased age-related physical reserve, is found in 56-79% of adults with end-stage HF receiving durable left ventricular assist device (dLVAD) therapy. Frailty increases risk of adverse events, including increased mortality in the dLVAD population, but less is known about depression, quality of life (QOL), cognition and frailty responsiveness. Therefore, we aimed to describe and compare frailty (5-Meter Walk Test, 5MWT), depression (Patient Health Questionnaire-9, PHQ-9), quality of life (EQ5D Visual Analog Scale, EQ-5D VAS) and cognition (Trailmaking B) from pre- to 12-months post-dLVAD We also compared demographics, clinical characteristics, and post-dLVAD …

Novel Mechanisms Of Protein Kinase C Α Regulation And Function, Xinyue Li

Theses & Dissertations

Protein kinase Cα (PKCα) is a member of the PKC family of serine/threonine kinases, which have been implicated in regulation of many cellular processes, including cell proliferation, differentiation, survival, and transformation. A large body of evidence from the Black laboratory and others support an anti-proliferative function of PKCα in normal epithelial tissues, including the intestinal mucosa and endometrial epithelium. PKCα is also tumor suppressive in epithelial cancers, such as colorectal cancer (CRC) and endometrial cancer (EC). However, a major obstacle to harnessing the tumor suppressive functions of PKCα to benefit patients is the widespread loss of PKCα expression in tumors. …

Theses & Dissertations

In the United States (US), African American (AA) men often face oppression, discrimination, negative interactions with the justice system, and significant economic, neighborhood, and social hardships over their life course. These challenges increase the risk of chronic exposure to stressful events with negative mental health outcomes, such as depression. Most of the research on parenting and parental depression has focused on mothers based on the premise that women are more often primary caregivers for their children, especially during early childhood. However, a growing number of fathers take on childcare responsibilities. Despite dealing with different life stressors and negative circumstances, AA …

Characterization Of Metastatic Cutaneous Squamous Cell Carcinoma In The Immunosuppressed Patient, Megan E. Wackel

Theses & Dissertations

Patients who are immunosuppressed, such as solid organ transplant recipients (SOTRs), are known to have a higher risk of developing cutaneous squamous cell carcinoma (cSCC). This population is at a higher risk of metastasis and worse disease-specific survival, with over 1 million cases and an estimated 3,932 to 8,791 deaths each year in the United States. Large cancer genomic databases have reported on genomic drivers for many cancer subtypes, yet cSCC has not been included.

Assessing The Methodology, Prevalence, And Associated Factors For Adverse Childhood Experiences (Aces) Among Children And Adolescents In The United States, Kiara L. Lyons

Theses & Dissertations

To comprehensively capture the risk and protective factors of ACE exposure and ACE-related outcomes, we propose to consider a social-ecological model framework. The concept of the Social-Ecological Model was originally introduced in the 1970s by psychologist Urie Bronfenbrenner and designed to theoretically capture the multifaceted influence different personal, social, and environmental factors have on health behaviors and outcomes. Additionally, this would help to determine what prevention and intervention methods would be more appropriate to implement. This conceptual framework had five system levels: microsystem (individual), mesosystem (interpersonal), exosystem (community context), macrosystem (societal and cultural influences), and chronosystem (internal and external elements …

Metoprolol Disrupts Sterol Biosynthesis Through Inhibition Of 7-Dehydrocholesterol Reductase (Dhcr7), Luke B. Allen

Theses & Dissertations

Cholesterol is essential for life. It is particularly important in the brain as it relies on de novo synthesis of cholesterol following the formation of the blood brain barrier (BBB). As such, disrupting sterol biosynthesis during neurodevelopment can have devastating outcomes. The most common post-lanosterol sterol biosynthesis disorder, Smith-Lemli-Opitz Syndrome, arises from a faulty DHCR7 enzyme. DHCR7 has also been shown to be inhibited by several psychotropic medications. Here we assess six beta-blockers and their effects on sterol biosynthesis in vitro. Two beta-blockers, metoprolol and nebivolol strongly inhibit DHCR7 in four separate in vitro models of both mouse and …

Open-Source Flight Data: Free, But At What Cost?, James Norman

Aviation Faculty Publications

The proliferation of open-source flight data has been heralded throughout the aviation industry, from air traffic service providers seeking efficiencies to the voyeuristic tracking of celebrity aircraft movements. However, the rise of open-source data presents challenges when juxtaposed against the traditional safety management systems that have sustained commercial aviation until now. Open-source data are not protected legally to the same extent as traditional flight data, and data from open-source platforms are not subject to the same validation standards as traditional flight data. Pilots are now able to interface with their own flight data, which diverges from the original aggregate intent …
