This program evaluation is guided by the CDC’s 6-step program evaluation framework (2), which was used to inform this assessment.

The Critical Role Of Nac1 In Triple-Negative Breast Cancer Stemness And Immunosuppression, Chrispus Ngule

Theses and Dissertations--Toxicology and Cancer Biology

Triple-negative breast cancer (TNBC) is a highly heterogeneous and the most lethal breast cancer (BC) subtype. We report here a new role of nucleus accumbens associated protein 1 (NAC1) in maintaining stemness signature and features of TNBC and controlling the status of myeloid-derived suppressor cells, which accounts for its role in tumor progression and metastasis. This report demonstrates increased NAC1 amplification in TNBC metastatic samples compared to nonmetastatic tissues. In vitro, NAC1 depletion in TNBC cells suppressed their proliferation, colony formation, migration, and invasion. In vivo, NAC1 knockdown in TNBC cells reduced tumorigenic ability, diminished tumor growth rate, and abolished …

Population Burden Of Rare Infectious And Inflammatory Diseases Of The Heart, Meera Marji

Theses and Dissertations--Epidemiology and Biostatistics

Rare diseases of the heart, such as infective endocarditis (IE), myocarditis, and pericarditis, have earned limited attention in cardiovascular research despite their potential for severe morbidity and mortality. Amidst the opioid crisis in the United States, there has been a notable increase in endocarditis hospitalizations among people who inject drugs. Kentucky, at the epicenter of the opioid epidemic, lacks available data on IE hospitalizations. Moreover, the COVID-19 pandemic has introduced unprecedented challenges to healthcare systems, influencing hospitalizations and healthcare utilization patterns. While trends before, during, and after the pandemic have been extensively studied for common cardiovascular diseases, such as heart …

Revolutionizing Our Understanding Of Specific Platelet-Pathogen Interactions, Hammodah Rawhi Hammodah Alfar

Theses and Dissertations--Molecular and Cellular Biochemistry

Aside from their classical role in maintaining hemostasis, platelets are considered first-line vascular guardians that influence both the innate and adaptive immune systems. This is mediated by either direct interactions with immune cells or through the release of pre-stored cytokines and chemokines upon interacting with pathogens such as viruses. While this establishes platelets as potential players in the response to pathogens, it remains unclear what platelets can do with pathogens and how important that is to immune responses, especially against viruses. Most systemic viremias, such as HIV-1, present with mild thrombocytopenia, which is mediated through several mechanisms such as a …

Chemical Control Of Turfgrass Diseases 2024, Bruce B. Clarke, Paul Vincelli, Paul Koch, Ming-Yi Chou

Agriculture and Natural Resources Publications

Turfgrasses under intensive management are often subject to outbreaks of infectious diseases. Diseases usually are most damaging when weather or cultural conditions favor the disease-causing agent but not plant growth and vigor. Cultural conditions that predispose turfgrass to diseases include close mowing, inadequate or excessive fertility, light or frequent irrigation, excessive thatch, poor drainage, and shade. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, …

Covid-19 And Access To Healthcare At The Crossing Of Race, Poverty, And Rurality, Shavonnie R. Carthens

Law Faculty Scholarly Articles

Black Americans make up 7.7 percent of the rural population in the United States. During the COVID-19 pandemic many in this population found themselves at a unique intersection of inequity - being Black, poor, and residing in a rural area. Poverty is a known contributor to negative health outcomes and is a risk factor for death from coronavirus infection. The association between race and poverty, when examining infectivity and mortality rates of COVID-19, have disproportionately devastated Black Americans and other minorities. Further, research indicates the presence of a general “rural mortality penalty” wherein rural Black communities have higher death rates …

Background: In the fall of 2023, vaccine recommendations included updated COVID-19 and influenza vaccines, as well as a new vaccine and immunization for respiratory syncytial virus (RSV). Vaccine co-administration, the administration of more than one vaccine in one vaccination session, is safe and effective for COVID-19, influenza, and RSV vaccines and can improve vaccine uptake for all recommended vaccines (Bonanni, et al., 2023; CDC, 2023). The COVID-19 pandemic altered the landscape for locations where people receive vaccinations, and it may be beneficial to public health to have …

Biodegradable Nanoparticles Targeting Circulating Immune Cells Reduce Central And Peripheral Sensitization To Alleviate Neuropathic Pain Following Spinal Cord Injury., Michael N. Saunders, Kate V. Griffin, Irina Kalashnikova, Daniel Kolpek, Dominique R. Smith, Eiji Saito, Brian J. Cummings, Aileen J. Anderson, Lonnie D. Shea, Jonghyuck Park

Pharmaceutical Sciences Faculty Publications

Neuropathic pain is a critical source of comorbidity following spinal cord injury (SCI) that can be exacerbated by immune-mediated pathologies in the central and peripheral nervous systems. In this article, we investigate whether drug-free, biodegradable, poly(lactide- co -glycolide) (PLG) nanoparticle treatment mitigates the development of post-SCI neuropathic pain in female mice. Our results show that acute treatment with PLG nanoparticles following thoracic SCI significantly reduces tactile and cold hypersensitivity scores in a durable fashion. Nanoparticles primarily reduce peripheral immune-mediated mechanisms of neuropathic pain, including neuropathic pain-associated gene transcript frequency, transient receptor potential ankyrin 1 nociceptor expression, and MCP-1 (CCL2) chemokine …

Delineating Contributions Of Genotype And Lineage To Lung Cancer Therapy Response, Kassandra Jo Naughton

Theses and Dissertations--Toxicology and Cancer Biology

Non-small cell lung cancer (NSCLC) heterogeneity is a major challenge for determining effective treatment strategies. Adenocarcinomas (ADCs) and squamous cell carcinomas (SCCs) are histologically and epigenetically distinct subtypes of NSCLC. Patients with ADC tumors harboring mutations in both KRAS and LKB1 (aka STK11) have lower survival rates than those with KRAS-only tumors. KRAS/LKB1 tumors are not only aggressive, but also respond poorly to immunotherapy. However, these data are limited to ADCs, and it is unclear if SCCs with this genotype are also resistant to immunotherapy. We developed a mouse model of Kras^mut/Lkb1^mut capable of producing …

Redefining Ed Utilization: A Rabies Post-Exposure Prophylaxis Perspective, David Bennington

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Rabies, though rare in the United States, remains a lethal viral disease with significant public health implications. Post-exposure prophylaxis (PEP) through timely administration of rabies vaccines and rabies immune globulin (RIG) is critical for preventing the progression of the virus following potential exposure. However, the current system of healthcare delivery in the United States has witnessed an alarming trend: the unnecessary utilization of emergency department (ED) visits for rabies PEP, including follow-up vaccinations. This paper aims to examine and address this issue through a review of the factors contributing to the inappropriate use of ED services for rabies treatment.

A Social History Of Opioids’ Crimedical Cycle, Jerel M. Ezell, Alex Rains, Babatunde Patrick Ajayi, Kyle Miller, Erin Augustine, Dawn Goddard-Eckrich, Elizabeth N. Kinnard, Michelle R. Lofwall

Behavioral Science Faculty Publications

Historically, public and political discourse around people who nonmedically use opioids has largely been rendered via a deficits-oriented lens, presenting this population as weak, disinterested, and deviant,and thus undesirable and ill-positioned for wellness and communal integration. These narratives, and subsequent policies used to engage people who use opioids, are intermittently formed and disrupted by geopolitical changes, as public and institutional attitudes, often driven by racial and class-related considerations, shift. As part of what we term the crimedical cycle, a population’s behaviors fluctuate between periods of medicalization and criminalization. Strengths-based theory, an offshoot of ‘positive psychology’ that helps contextualize the crimedical …

Background Pediatric acute transverse myelitis (ATM) accounts for 20–30% of children presenting with a first acquired demyelinating syndrome (ADS) and may be the first clinical presentation of a relapsing ADS such as multiple sclerosis (MS). B cells have been strongly implicated in the pathogenesis of adult MS. However, little is known about B cells in pediatric MS, and even less so in pediatric ATM. Our lab previously showed that plasmablasts (PB), the earliest B cell subtype producing antibody, are expanded in adult ATM, and that these PBs produce self‑reactive antibodies that target neurons. The goal of this study was to …
