Appearance Over Function - The Impact Of Long-Term Oral Contraceptive Use On Brain Development, Breast Tissue Composition, And Future Lactation Outcomes, Fiona M. Wang

Dissertations

This integrative review examines the long-term effects of combined oral contraceptive (COC) use beginning in puberty on brain development, breast tissue composition, and future breastfeeding outcomes. Puberty is a critical developmental stage during which hormonal changes significantly impact the neurological and reproductive systems. The introduction of synthetic estrogen and progestin through COC use during this time may disrupt natural hormonal pathways, potentially altering neuroendocrine signaling and breast tissue maturation. Such changes may have lasting consequences, including impaired milk production, a weakened milk ejection reflex, disrupted maternal-infant bonding, and reduced overall breastfeeding success. The review synthesizes findings from endocrinology, neuroscience, and …

Faculty, Staff and Students Publications

Chagas disease, caused by the protozoan Trypanosoma cruzi, is a significant challenge for canine health, with limited diagnostic tools. This study assessed the performance of a novel Tc-24 recombinant antigen ELISA compared to three commercial diagnostic tests on 70 serum samples from kennel dogs in Texas. The Tc-24 ELISA demonstrated high sensitivity (87.5%) and specificity (91.2%) compared to Indirect Fluorescent Antibody (IFA) testing, with significant differences in Tc-24 optical density (OD) between positives and negatives (0.607 vs. 0.089, p < 0.001). When compared to Chagas Stat-Pak (SP), Tc-24 ELISA showed sensitivity and specificity values of 82.1% and 86.7%, respectively (p < 0.001). For Chagas Detect Plus (IB), the assay achieved a sensitivity of 80.0% and specificity of 93.1% (p < 0.001). Spearman correlation analysis revealed significant associations between Tc-24 OD and SP (r = 1.0, p = 0.0167), IB (r = 0.9, p = 0.0833) and IFA (r = 0.6273, p = 0.044). Elevated immunochromatographic values in commercial kits (SP or IB) correlated with Tc-24 OD (1.17 vs. 0.039, p < 0.001), achieving 100% sensitivity and 95.8% specificity based on positive results from commercial kits. These findings suggest that Tc-24 ELISA is a reliable and accurate serological tool for diagnosing T. cruzi infection in dogs, with the potential to enhance diagnostic capabilities in veterinary medicine.

The Role Of Serum Phosphate Control In Supporting Transplant Readiness In Patients On Dialysis, Laura A Williams, Stephen Z Fadem

Faculty, Staff and Students Publications

Chronic kidney disease affects over 36 million Americans, with more than 800,000 progressing to end-stage kidney disease (ESKD). Treatment with kidney transplantation offers superior survival, quality of life, and cost-effectiveness compared with dialysis, yet access remains limited. Hyperphosphatemia is a highly prevalent and modifiable complication of ESKD that contributes to cardiovascular disease, mineral bone disorder, and potential pulmonary dysfunction. Additionally, elevated serum phosphate has been linked to transplant graft failure and adverse post-transplant outcomes. Although normal phosphate levels are not formally required for transplant eligibility, they are frequently considered as part of transplant readiness assessments. Persistent gaps between clinical guideline …

Public Support For And Reactive Behavior Toward Technological Risk Interventions: An Extension Of Secondary Risk Theory, Hye Kyung Kim, Rui Gu, Fiona Goh, Sonny Rosenthal, Shirley S. Ho

Research Collection College of Integrative Studies

Project Wolbachia is a dengue control initiative in Singapore. Guided by Secondary Risk Theory, this study examined how primary (dengue) and secondary (Wolbachia) threat and coping appraisals shape public support and reactive behavior toward the project. A nationally representative survey of 1,000 Singaporeans showed that support was positively linked to the perceived primary risk, the efficacy of the project and the government, while negatively related to the perceived secondary risk. Reactive behavior was positively associated with perceptions of both primary and secondary risk. Media attention and trust in the government indirectly influenced support and behavior moderated by knowledge.
