Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.

An Engine, Not A Vessel: Place, Politics, And Health In The United States, Philip B. Rocco

Political Science Faculty Research and Publications

Social scientists often treat places as containers for social and economic phenomena that shape health outcomes. Yet this analytic practice conceals more than it reveals. Local governments in the United States should be understood as engines of both health promotion and stratification. As the contributions to this symposium suggest, governments not only occupy a formal place in the U.S. public health system, their decisions on everything from housing to transportation infrastructure can also have profound impacts on health outcomes. Local political economies likewise renegotiate the parameters of acceptable health interventions, public understandings of health disparities, and the status of population …

Economic Exchange And Relational Work In Doubled-Up Households, Hope Harvey

Sociology Faculty Publications

Doubling up, or sharing a home, is an increasingly common way that families make ends meet. Drawing on over 170 in-depth interviews with 60 parents, I ask how doubled-up household members understand and contest their economic relationships. I show that the success of intra-household economic exchange depends not only on the amounts exchanged, but also the shared meanings behind these exchanges. Given the lack of institutionalized expectations guiding doubled-up household relationships, household members draw on competing norms, framing the household as either a solidarity unit or a series of independent nuclear family units. Although disagreement over economic relationships is common, …

Perceived Adolescent Insecure Attachment With Mothers And Fathers, Helena Pipová, Martin Dolejš, Jaroslava Suchá, Alexander T. Vazsonyi

Sociology Faculty Publications

The aim of this study was to test relationships between adolescent insecure attachment (anxious and avoidant) with mothers and fathers and three outcomes: food addiction, eating disorders, and weight status, in a large multi-regional sample of Czech adolescents. Anonymous, self-reported data were collected from 3,677 adolescents (1,688 boys, 45.9% and 1,989 girls, 54.1%). Both anxious and avoidant attachment with mothers were positively associated with food addiction (p <.001) and eating-disorder risk (p <.001). Importantly, avoidant attachment with fathers uniquely and additively explained variance in both food addiction (p <.001) and eating-disorder risk (p =.003), after controlling for maternal attachment. Weight status was unrelated to attachment and was predicted by sex and parental education only. Study findings highlight the salience of insecure attachment with both mothers and fathers for food addiction and eating disorders among adolescents and identify the parental relationship as a key potential preventative strategy.

Fda After Loper Bright, Erika Lietzan

Faculty Publications

Loper Bright, which overruled the Chevron decision from 1984, tells us that a court should determine the meaning of all statutory provisions for itself, rather than deferring to the views of the federal agencies that implement those provisions. But the overruling of Chevron may have less of an impact on the U.S. Food and Drug Administration than conventional wisdom supposes. Most challenges to FDA action do not concern its statutory interpretations. And the agency prevailed in most cases involving statutory interpretation, before the Chevron doctrine took hold. After 1984, when the doctrine did apply, the agency often lost cases at …

The Suppression Of The Opelousas Massacre Of 1868: The Blackleg Hunt Or “La Chasse A’ La Jambe Noire”, August Malveaux

The Griot - Southern Conference on African American Studies, Inc.

This article examines the suppression of the 1868 Opelousas Massacre—also known as “la chasse à la jambe noire” or the Blackleg Hunt—and situates it within the broader landscape of Reconstruction-era racial violence in Louisiana. Malveaux argues that the massacre was not an isolated riot but a premeditated act of political terrorism designed to eliminate Black electoral participation and reverse Reconstruction gains. Triggered by Black political mobilization and white supremacist resistance, the violence unfolded over several days in September 1868 and resulted in widespread murder, intimidation, and property destruction. The essay challenges the historiographical minimization of the event, emphasizing how organized …

Ai-Driven Risk Forecasting For Strengthening The United States Food Supply Chain Resilience: Case Study: A National Ai-Enabled Food Supply Chain Risk Forecasting Framework And A Data Analytics Approach To Predicting Disruptions, Sarah Onyeche Usoro, Itua Austin Omogiate, Rahab Zhewe Felix, David Azikutenyi Galadima

Student Publications

The United States food supply chain is one of the most complex and interconnected systems in the world, spanning agricultural production, processing, transportation, storage, and retail distribution. While this complexity enables efficiency and scale, it also increases vulnerability to disruptions caused by climate change, labor shortages, geopolitical shocks, transportation failures, cyber threats, and public health crises. Conventional risk management methods, often reactive and siloed, have proven inadequate in predicting and mitigating systemic shocks that have become frequent occurrences in today’s world. This article examines how artificial intelligence (AI) and data analytics can transform risk forecasting in U.S. food supply chains …

Dietetics and Human Nutrition Faculty Publications

This study qualitatively examined college students' perceptions of a pilot cooking and nutrition workshop, College Cooking Connection (CCC), through the Social Cognitive Theory (SCT) framework. Undergraduate students who attended at least one CCC workshop (N = 29) were invited to a 30 min virtual focus group. A trained moderator guided the discussion to gather perceptions of the program. Themes were identified using thematic analysis with a directive and deductive approach based on SCT. Focus groups revealed eight major themes across the SCT. Cognitive themes included: (1) improved nutrition literacy, (2) understanding the nutrition-mental health connection, and (3) increased awareness of …

Soil Nutrient Sufficiency Versus Plant Nutrient Status In Compost-Amended Soils: Plant Tissue Analysis As A Diagnostic Tool, Chandralekha Joga Miss

Murray State Theses and Dissertations

This study evaluated whether Mehlich III soil nutrient sufficiency ratings reliably predict plant nutrient status and chlorophyll response across contrasting compost application histories. A greenhouse pot experiment was conducted with Chijimisai (Brassica rapa) planted in three treatment soils that had no compost (T1), moderate compost history (T2), and long-term hog manure compost application (T3). Plant performance was assessed through weekly shoot length and chlorophyll content (SPAD) measurements, leaf number at maturity, and leaf tissue nutrient analysis conducted at harvest. Soil test results indicated adequate to high nutrient levels across all three treatments. Leaf tissue analysis, however, revealed substantial …

Do Magnesium Ions Have Similar Effects As Calcium Ions On Resting Membrane Potential?, Anthony Hana, Youngwoo Kim, Joy Bidros, Katie Neglia, Robin L. Cooper

Biology Faculty Publications

Maintaining a membrane electrical potential of biological cells is a dynamic process, as some cells have a continually changing potential, like pacemaker cells, while other cells may function with large or small changes in the membrane potential. Additionally, some cells may change their electrical potential when stimulated or inhibited by electrical signals, chemical compounds, or both—either simultaneously or episodically. The persistent leak of K⁺ through two-pore-domain potassium channels (K2P) and of Na⁺ through Na⁺ leak channels (NALCNs) and the action of pumps and exchangers are primarily responsible for maintaining a resting potential. Ca²⁺ ions are known …

Addressing Obesity And Diabetes In Appalachian Kentucky, Hannah E. Orens

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

Type 2 diabetes and obesity are major public health concerns in Appalachian Kentucky. Populations in this region experience much higher rates of chronic disease than the rest of the state, have limited access to preventive care, and ongoing economic challenges that affect health. Many rural counties face increased poverty, transportation challenges, and shortages of healthcare professionals, all of which contributed to poor health outcomes and reduced access to evidence-based prevention programs. As a result, there is a strong need for focused, feasible, community-based interventions that improve access to evidence-based prevention while addressing the social and economic factors influencing health in …

Purchasing A Healthier Future: A Nutrition-Focused, Community-Centered Approach To Reduce Obesity And Diabetes In Graves County, Kentucky, Marissa Stephens

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

Obesity and type 2 diabetes are among the most significant public health challenges in the United States, with Kentucky consistently ranking among the states with the highest prevalence of both conditions. Together, these conditions contribute to reduced quality of life, rising healthcare costs, and increased morbidity and mortality, underscoring the need for targeted, community-centered interventions. The disease burden of obesity and diabetes is particularly pronounced in rural areas, including the state’s westernmost region, the Jackson Purchase. Among rural populations, chronic disease risk is driven by a combination of factors, including low socioeconomic status, limited access to healthcare/supermarket options, and food …

Reproductive Success Is Secured By A Rapidly-Evolving Short Peptide In Female Aedes Aegypti Mosquitoes, Priyanka Lakhiani

Student Theses and Dissertations

The mosquito lineage spans hundreds of millions of years of evolution, and this period has honed the yellow fever mosquito, Aedes aegypti, into a precise and expert predator. While nectar and plant-derived carbohydrates are sufficient sources of nutrition to maintain energy and metabolism, female mosquitoes must acquire multiple ingredients to successfully reproduce and produce offspring. Healthy, motile sperm from a conspecific male and a complete blood meal from a human host are required for females to develop viable eggs, and thus ensure species survival. What are the internal mechanisms that coordinate the acquisition of these key elements with the maturation, …

Dining In The Dark Atp Sensing In The Female Aedes Aegypti Mosquito, Katherine Adriana Rosas Villegas

Student Theses and Dissertations

Blood feeding is fundamental for female Aedes aegypti mosquitoes, which require this protein-rich meal for egg development. After being attracted to a human host by sensory cues such as body odor, body heat, and carbon dioxide exhaled in human breath, the mosquito lands and probes under the skin to feed on blood. Probing uses the stylet, a sharp appendage ensheathed in the mosquito labium that punctures the skin and is highly specialized for blood ingestion. Previous work from the lab with GCaMP calcium imaging of stylet neurons showed that approximately 50% of stylet neurons respond to blood, and that these …

Using Nmr Spectroscopy And Linear Discriminant Analysis To Molecular Profile Varietal Honey, Taylor Mac

Master's Theses and Doctoral Dissertations

In recent years, varietal honey has been a massive target of adulteration through mislabeling and the addition of other sugars. Unethical companies do this to cut production costs while still charging the consumer full price. Previous studies have used nuclear magnetic resonance (NMR) to unravel possible adulteration in honey, but currently, there are no standard rapid methods to authenticate varietal honey. In our research, we collected NMR signatures (“fingerprints”) and combined them with linear discriminant analysis (LDA) to predict the varietal, country, and region of varietal honey. As a part of the project, we investigated whether an adjustment to the …

Enhancing Postoperative Esophagectomy Outcomes With Preoperative Education: A Quality Improvement Project, Gaelyn Kattman

DNP Projects

Title

Enhancing Postoperative Outcomes with Preoperative Education for Esophagectomy Patients

Background/Significance

Esophageal cancer is an aggressive disease and the fourth most common gastrointestinal cancer. A surgical treatment for a patient with esophageal cancer who is a surgical candidate is an esophagectomy. Immediate postoperative complications may include pneumonia, arrhythmias or anastomotic leaks, all of which can potentially increase the patient’s length of stay. Delayed discharges can lead to a backup throughout the hospital, limiting the amount of available inpatient beds for patient care.

Purpose 

The DNP project purpose was to implement an additional preoperative telehealth visit in order to provide  patient …

Predictors Of Increased Length Of Stay And Cost In Readmissions For Spinal Surgical Site Infections, Matthew Giammanco, Alex Zhang, Phillip Alexeev, Ryan Snowden

SPARK Symposium Presentations

Abstract:

Background

Surgical site infection (SSI) following spinal surgery remains a costly and morbid complication, frequently necessitating hospital readmission and operative management. While prior studies have characterized the overall economic burden of spinal SSI, the specific drivers of cost during SSI-related readmissions are poorly defined. The primary research question of this study was to identify clinical, operative, and microbiologic factors associated with increased hospital cost, length of stay, and financial margins during readmission for operative management of spinal SSI.

Methods

We performed a retrospective cohort study of adult patients readmitted for surgical management of spinal SSI at a single tertiary …

Leveraging Research-Based Knowledge Translation Via Rural Libraries To Improve Maize Postharvest Practices In Uganda, Jackline Estomihi Kiwelu, Patrick Ngulube

Libraries

Background: Rural community libraries are increasingly recognised for providing localised knowledge, yet their potential to support agricultural extension services and improve access to postharvest knowledge in Uganda remains underexplored.
Objectives: This study examined the postharvest information needs of smallholder maize farmers and explored how community libraries can be leveraged to translate and repackage research-based knowledge to meet these needs.
Method: A mixed-methods parallel design was employed. Data were collected from a survey of 312 maize farmers, personal interviews and two focus group discussions (FGDs) with 22 extension workers and four librarians. Desk research was conducted to analyse relevant documents. Quantitative …

Alcohol Consumption Exacerbates High-Fat Diet- Mediated Disruptions In Myelopoiesis And Osteoclastogenesis In Mouse Models Of Metabolic Dysfunction-Associated Liver Diseases, Hami Hemati, Madison B. Blanton, Lauren Rutt, Nicholas Keiran, Rebecca Geron, Florence Lima, Rebecca L. Mccullough, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Objective: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) and Metabolic Dysfunction-Associated Alcohol-related Liver Disease (MetALD) exhibit systemic immune abnormalities. Given that such immune dysregulation is closely linked to the skeletal complications frequently observed in MASLD and MetALD, we sought to comprehensively characterize the bone marrow hematopoietic compartment and its link to osteoclastogenesis.

Methods: We utilized bone marrow from mouse models of MASLD (high-fat diet, HFD) and MetALD (high-fat diet plus ethanol, HFD+EtOH), followed by flow cytometric analysis to phenotype hematopoietic stem and progenitor cells (HSPCs), as well as in vitro and in vivo assays to evaluate osteoclastogenesis.

Results: We found that …

“Why Can’T I Do My Homework Without Crying?” Neurodivergence And The Gendered Expectations Of Functioning, Alia Wang

Pitzer Senior Theses

The purpose of this qualitative interview study was to examine the experiences of neurodivergent women and gender-diverse individuals regarding productivity. Neurodivergence is often understood in biological and medical terms; far less attention has been given to how neurodivergent individuals experience and navigate everyday life. Meanwhile, productivity is often framed as a neutral measure of efficiency, but in practice, it is shaped by social norms that shape particular ways of thinking, working, and behaving.

Particularly for women and gender diverse people, these expectations are compounded not only by cognitive differences but also by gendered norms around behavior. This creates a mismatch …

Chronic Alcohol Consumption Disrupts The Gut Microbial And Metabolic Landscapes, Madison B. Blanton, Ethan G. Napier, Katelyn E. Keen, Ethan V. Stuart, Isaac R. Cinco, Hami Hemati, Ronald C. Bruntz, Landon Wilson, Stephen Barnes, Rupak Khadka, Kathleen A. Grant, Ilhem Messaoudi

Pharmaceutical Sciences Faculty Publications

Introduction: Alcohol use disorder (AUD) increases incidence of infections, organ damage, and cancers. Aberrant inflammation is likely a driver of these adverse outcomes. Indeed, chronic alcohol consumption (CAC) rewires macrophages/monocytes toward a hyper-inflammatory phenotype. Prior studies showed increased gut permeability and dysbiosis. Translocation of host- and microbial-derived metabolites could trigger the hyper-inflammatory responses generated by macrophages/monocytes. However, the exact changes in these metabolites remain poorly defined due to confounders that complicate clinical studies and the differences between human and rodent gut microbiomes.

Methods: Here, we utilized a non-human primate model of ethanol self-administration to characterize alcohol-induced alterations in gut microbes …
