Institute of Child Nutrition, Applied Research Division

The increasing prevalence of ultra-processed foods (UPFs) in children’s diets presents a significant public health concern due to associations with obesity, metabolic disorders, poor cardiometabolic health, and reduced academic performance. Scratch cooking in school meal programs has emerged as a promising strategy for improving meal quality by emphasizing preparation from basic, minimally processed ingredients. Although research indicates that scratch-prepared meals can improve nutritional quality and student acceptance, implementation remains challenging due to operational, financial, and workforce barriers.

The purpose of this study was to identify challenges school nutrition professionals face when offering scratch-prepared meals, assess the national prevalence of these …

Covering The Care: The Fourth Trimester, Susy Hawes

All Materials

The weeks following the birth of a baby are often described as a time of extremes: profound joy paired with deep exhaustion, vulnerability, and adjustment. For birthing people, this period involves physical recovery from childbirth, dramatic hormonal shifts, disrupted sleep, learning to feed and care for an infant, and navigating major emotional changes. While some new parents have strong support systems, others face isolation, housing instability, or unsafe home environments. This critical 12-week period after birth is now widely known as the “fourth trimester.” Although the language is new, the reality is not. Across cultures and history, the postpartum period …

Chemistry Faculty Research & Creative Works

Preferential fluid flow remains a major challenge in subsurface energy production and gas storage operations, resulting in excessive water production in mature oil fields, reduced heat extraction in geothermal reservoirs, and low sweep and storage efficiency in CO₂-EOR projects. Polymer gels are widely used to mitigate high-permeability channels; however, conventional systems exhibit limited plugging efficiency and short lifetimes in ultra-high-temperature reservoirs due to poor thermal stability. This study presents a novel ultra-high-temperature-resistant preformed particle gel (UHT-PPG) developed for conformance control in reservoirs with temperatures of 150–275 °C and severe super-K or channeling problems. The material was evaluated in …

Progression Toward Terminal Oxidation Of Starch Via Hybrid Organic–Enzymatic Bioanode For Renewable Carbohydrate Conversion, Adam Milam, Jose Intano, Shelley D. Minteer

Chemistry Faculty Research & Creative Works

The performance of starch-based biofuel cells is fundamentally limited by inefficient utilization of the fuel's inherent energy density. Sequential oxidation of carbohydrate fuels, such as glucose, the monomeric unit of starch, using minimal catalyst systems has therefore emerged as a promising strategy to improve biofuel cell efficiency. Here, we extend a previously reported three-catalyst, organic–enzymatic glucose oxidation cascade to polymeric carbohydrate fuels by integrating enzymatic starch depolymerization with downstream electrochemical oxidation. To our knowledge, this represents the first demonstration of a defined hybrid organic–enzymatic cascade designed to drive progression of starch-derived glucose equivalents toward terminal oxidation using a minimal catalyst …

Impact Of Oxidative Stress On Mapk Signaling In Human Pancreatic Ductal Cell Line, Alexis Fink

Theses

The main processes linked to diabetes (type 1 or type 2) and obesity are impaired insulin production and glucose intolerance. The imbalance between antioxidant defense systems and oxygen-reactive species are known as oxidative stress. Understanding oxidative stress and its substantial effects on diabetes is crucial. Reactive oxygen species (ROS) can activate mitogen-activated protein kinases (MAPKs). We hypothesize that altered MAPK phosphorylation and hence downstream signaling is associated with changes in oxidative stress in the human pancreatic duct epithelial cell line (H6C7). While H6C7 cells are often engineered to be cancerous precursors, the natural phenotype of these cells and their expression …

Effects Of Energetic State On Male Mating Preferences In Poeciliid Fishes With Differing Mating Strategies, Katherine E. Taylor

Theses

Reproduction is energetically costly, making condition (i.e., energetic state) a potential factor in shaping reproductive behavior. However, its role in male mate choice remains largely unexplored. Here, we investigate condition-dependent effects on male mate choice in two species of Poeciliids: one coercive species (Gambusia affinis) and one courting species (Xiphophorus hellerii). Diet treatments were used to manipulate male and female conditions, and male preferences were assessed in dichotomous-choice tests using animated female stimuli. X. hellerii males showed a preference for high-condition females, whereas G. affinis males showed no overall net preference. Diet influenced preference in G. affinis, with high-fed males …

Epidemiology and Environmental Health Faculty Publications

Background: Diabetes self-management education and support (DSMES) is an evidence-based intervention that improves outcomes for people with diabetes, but uptake is <10%. We conducted a pilot pragmatic trial to increase DSMES in rural primary care clinics that integrated health information technology with a quality improvement (QI) learning collaborative. Methods: Two healthcare systems from rural Kentucky participated in the study. Within each system, 2 clinics received the intervention and 1 clinic served as a control (N = 6 clinics). Each intervention clinic identified a QI team (5-6 individuals) who participated in a 9-month QI learning collaborative followed by 5 months of follow-up. Our primary outcome was DSMES referrals; secondary outcomes were DSMES attendance and percentage with A1c >9%. Results: The 6 study clinics served 1,803 patients with diabetes; n = 1083 (60.1%) from 4 intervention clinics and n = 720 (39.9%) from 2 control clinics. DSMES referrals significantly increased in the intervention clinics compared to the control clinics (31.7% vs 0.1%, P < .001) and continued to increase throughout 5-month follow-up (40.0% vs 0.1%, P < .001). Conclusions: A structured QI intervention can significantly increase DSMES referral rates in primary care clinics. Findings highlight the potential of systems-level approaches to address persistent gaps in diabetes care delivery in rural settings.

Decreased Exercise-Induced Pulmonary Capillary Recruitment In Pulmonary Arterial Hypertension, David Langleben, Stylianos E. Orfanos, Benjamin D. Fox, Michele Giovinazzo, Magali Kaddis, John D. Catravas

Bioelectrics Publications

The human lung normally accommodates exercise-induced cardiac output increases mainly via recruitment of non-concomitantly perfused pulmonary capillaries. Recruitment is detectable by measuring the first-pass transpulmonary metabolism of ³H-benzoyl-Phe-Ala-Pro, providing an estimate of functional capillary surface area (FCSA). Pulmonary arterial hypertension (PAH) results from luminal narrowing of small precapillary arterioles, reducing downstream perfused FCSA. We hypothesized that exercising PAH patients would not be able to recruit FCSA normally. We studied two patients with severe PAH. Despite exercising to maximal dyspnea, neither could recruit FCSA. These limited data are the first direct measurements of FCSA in exercising PAH patients.

Effects Of The Menstrual Cycle Phase On Rpe, And Symptom Characteristics In Pre-Professional Female Soccer Players, Emily Potts

College of Graduate Studies: Theses & Dissertations

Hormonal fluctuations across the distinct phases of the menstrual cycle have been shown to influence physiological and psychological responses to exercise, with some evidence suggesting phase-dependent changes in symptom presentation and ratings of perceived exertion (RPE); however, findings remain inconsistent, and few studies have examined these relationships across an entire competitive season in female soccer players. The purpose of this study was to examine changes in RPE and menstrual symptoms across cycle phases, as well as the relationships between RPE and symptom reporting in pre-professional female soccer players. A total of 22 female soccer players (age 22± 1.85) were recruited …
