The Association Of Motherhood And Maternal-Related Life Events And Cardiovascular-Related Health, Disease Events, And Mortality, Taishayla Mckitt

ETDs from 2020-2029

More than 40% of U.S. women have cardiovascular disease (CVD), and nearly half have at least one major risk factor. Sparse evidence exists related to the role of childrearing (regardless of prior pregnancy) on CVD. A recent literature review highlighted the influence of reproduction on CVD and health and identified opportunities for advancement. At present, it has yet to be discovered from prospective epidemiologic studies the extent to which parenting and maternal events have influence on cardiovascular health and clinical events. It has been demonstrated that parous women have greater prevalence of cardiovascular risk factors (e.g., short sleep duration and …

Independent And Combined Effects Of Early-Life Iron Deficiency And Antibiotic Exposure On Growth And Hematological Outcomes In A Piglet Model, Ginger M. Fitzpatrick

Master's Theses

Iron deficiency (ID) affects over 2 billion individuals globally. Children under 5 are at increased risk of ID due to rapid growth and are especially vulnerable to its negative consequences because of iron’s essential role in cognitive development and immune maturation. ID is the leading cause of iron deficiency anemia (IDA), with IDA affecting approximately 40% of children in this age group. Antibiotic (abx) exposure is also prevalent during early life and may disrupt growth and through gut dysbiosis, with increasing use posing additional risk in younger populations. Geographically, there is overlap in regions with high anemia prevalence and those …

Effects Of Irrigation And Nitrogen Management On Yield And Leaching Risk In Organic And Conventional Broccoli Fields, Shane Egerstrom

Master's Theses

Under regulatory pressures to reduce groundwater contamination by nitrate from fertilizer, such as those posed by the Central Coast Regional Water Quality Control Board’s Agricultural Order 4.0, a need exists to better understand interactions between irrigation and nitrogen (N) management. To increase N use efficiency (NUE), growers are encouraged to account for additional sources of N in their management plans, such as irrigation water N and preplant soil N. The availability of these N sources for plant uptake and how it is affected by other management conditions is not yet well documented. We conducted 6 field trials, 3 organic and …

Animal and Food Sciences Faculty Publications

Combined modulation of the hypothalamic–pituitary–thyroid (HPT) and hypothalamic–pituitary–adrenal (HPA) axes is known to play a critical role in maintaining physiological stability in response to stress. In this study, stress induced modulation of these axes was examined using 20 pigs/treatment either weaned (WN), weaned with feed/water restriction 9 h (FR), transported 9 h (TRANS), or remaining with sow (SOS) and euthanized at 32 or 56 h post-weaning. Serum cortisol, thyroxine (T4), and triiodothyronine (T3) were measured before weaning and after 24, 32, and 56 h with no difference in cortisol concentrations among treatments at any timepoint. However, both T3 and T4 …

Assessing Aflatoxin Knowledge, Perceptions, And Related Practices, In A Rural Coastal Community: A Population-Based Cross-Sectional Survey, Rosebella Iseme, Joseph Abuodha, Anthony Ngugi, Innocent Abayo, Mansoor Saleh

Population Health, East Africa

Background

Aflatoxin contamination is a significant yet under-addressed food safety challenge in low-resource settings, driven by a complex interplay of environmental, agricultural, and socio-economic factors. Limited access to agricultural inputs, inadequate post-harvest handling and storage, and weak regulatory enforcement alongside food scarcity and climate change heighten the risk of contamination and exposure. Human exposure is associated with serious health consequences, including hepatocellular carcinoma, immune suppression, and childhood stunting. Although aflatoxin is increasingly recognized as a global food safety concern, little is known about community-level knowledge, risk perceptions, and preventive practices. This study examined household heads’ awareness, perceptions, and behaviours related …

All Peer-Reviewed Publications

This work investigated the effects of black soldier fly ( Hermetia illucens L.) larvae meal (BSFLM) on growth- and immune-related gene expression in Ross 308 broilers. Birds were fed diets containing soybean meal (SBM), fishmeal (FM), combinations with BSFLM, or BSFLM alone. Growth, organ weights, immune genes [interleukin-2 (IL-2), interleukin-6 (IL-6), tumor necrotic factor alpha (TNF-α), interferon-gamma (IFN-γ)] and growth-related genes [chicken growth hormone (cGH), insulin growth factor 1 (IGF-1)] expression were measured. Our results demonstrate that birds fed FM+BSFLM had significantly higher final liveweight, average daily weight gain (ADG), and low feed conversion ratio. Birds fed FM+BSFLM showed highest …

Paying For Participation: Equitable Compensation Models For Community Co-Researchers, Jamie Zimmerman, Prabhneet Girn

The Foundation Review

Community-engaged research is increasingly central to philanthropic practice, yet funders rarely provide guidance for compensating community members who participate as co-researchers. This gap is especially pronounced for youth, who often face administrative, legal, and developmental constraints that complicate what “fair pay” looks like in practice.

This article presents findings from a mixed-methods comparative case study of three youth participatory action-research projects involving 44 youth ages 16–24 across varied organizational settings. Data were collected through youth surveys, focus groups, staff interviews, financial analysis, and document review.

Findings show that each model carries distinct trade-offs related to feasibility, transparency, and administrative capacity, …

The Putative Role Of Oral Microbiome In Premature Aging During Hiv Infection: What Do We Know?, Carlos Solá-Morlá, Daphne Alcalá-Zúñiga, Juan Araujo, Maria Da Gloria Bonecini-Almeida, Upal Roy, Josué Pérez-Santiago

Health & Biomedical Sciences Faculty Publications

Despite improvements in life expectancy, people with HIV (PWH) are at risk of developing HIV-associated comorbidities at a younger age when compared to HIV-uninfected individuals. This premature aging process can be attributed to various factors, such as the prolonged exposure to combination antiretroviral therapy (cART), inflammation, microbial perturbances and oxidative stress. Similarly to the gut, oral dysbiosis occurs in HIV-1 infection, with cART and inflammation playing a crucial role. This gives rise to an enrichment of pathogenic microorganisms that in turn, elicit an immune response tied to chronic inflammation. Consequently, cART exposure, dysbiosis and persistent inflammation in HIV-1 infection have …

Precision Nutrition In Breast Cancer: Towards Patient- And Tumour-Informed Dietary Strategies, Cristina Crespo-García, R. Taaffe, Carolyn Peddle-Mcintyre, Emily Jeffery, John P. Campbell, Robert Thomas, Daniel A. Galvao, Robert U. Newton

Research outputs 2022 to 2026

Dietary strategies are increasingly recognized as important modulators of breast cancer outcomes, acting through effects on metabolic regulation, weight management, hormone signalling, immune function, and the gut microbiome. However, breast cancer heterogeneity and inter-individual variability mean that generic dietary guidelines may not fully capture patient needs. Precision nutrition offers the opportunity to align dietary interventions with tumour subtype, treatment context, and host biology, potentially enhancing therapeutic response and survivorship in patients diagnosed with breast cancer. In this narrative review, we summarize evidence on dietary patterns and prognosis, and explore how targeted interventions, including fasting regimens, ketogenic diets, and caloric restriction, …

The Color Of Combat: How Subtleties Of Resource Value Alter The Effects Of Fighting Ability In Hermit Crab Contests: How Subtleties Of Resource Value Alter The Effects Of Fighting Ability In Hermit Crab Contests, Thomas M. Chatfield, Mark Briffa

School of Biological and Marine Sciences

During contests over resources, the intensity of fighting and the outcome is often influenced by an interaction between the difference between opponents in the fighting abilities (resource holding potential [RHP]) and the difference in how they subjectively value the resource. Additionally, because fighting can involve vigorous activity, engaging in a fight can make the opponents more noticeable to predators. Thus, predation risk, alongside resource value (RV), may interact with the effects of RHP difference. During hermit crab contests over the ownership of empty gastropod shells attackers perform vigorous shell rapping, whereas defenders adopt a protective posture inside their shells. This …
