The Role Of Dna Methylation In White Matter Hyperintensity Burden: An Integrative Approach, Yunju Yang

Dissertations and Theses (Open Access)

Cerebral white matter hyperintensities (WMH) on MRI are an indicator of cerebral small vessel disease, a major risk factor for vascular dementia and stroke. DNA methylation may contribute to the molecular underpinnings of WMH, which are highly heritable. We performed a meta-analysis of 11 epigenome-wide association studies in 6,019 middle-aged to elderly subjects, who were free of dementia and stroke and were of African (AA) or European (EA) descent. In each study, association between WMH volume and each CpG was tested within ancestry using a linear mixed model, adjusted for age, sex, total intracranial volume, white blood cell count, technical …

Exploration Of Breastfeeding As A Protective Factor For Breast Cancer In South African Women: A Nested Case-Control Study, Booker S. Quiera

Dissertations and Theses (Open Access)

Background. South African’s (SA) breast cancer incidence rate is continually increasing (39 per 100,000 (2012) versus 46.2 per 100,000 (2018) with trends towards later-stage diagnosis. In previous literature, breastfeeding has been assessed as a protective factor for breast cancer; however, the SA population experiences inconsistent breastfeeding trends, rates, and support services. Therefore, this study will evaluate the inverse association between breast cancer and breastfeeding history. Methods. Cases (breast cancer) and controls (mastalgia) were matched 1:1 on clinical visit from May-August 2019 at Groote Schuur Hospital (GSH) in Cape Town, Western Cape, South Africa. Breastfeeding history, breast carcinoma diagnosis, and clinically …

The Influence Of Sodium And Potassium On Blood Pressure Genetics In The Population Architecture Using Genomics And Epidemiology Study, Cynthia S. Bell

Dissertations and Theses (Open Access)

Multiple polymorphisms have shown associations with blood pressure (BP) levels and hypertension status, but the overall genetic effect on BP has been small and accounts for only a small fraction of the variation in population-wide BP characteristics. These weak associations of BP with genotype may not be attributable to the examining the “wrong” single nucleotide polymorphism (SNP) but may instead be the result of noisy BP phenotypes based on mmHg alone. Adding information from the underlying mechanisms of nutritional intake, reuptake, and excretion on BP may produce more informative BP phenotypes to study. To explore this complex relationship between diet, …

Estimating Children’S Health Risks From Recreational Beach Play Following An Oil Spill, Tanu K. Altomare

Dissertations and Theses (Open Access)

Environmental contamination from marine oil spills can have damaging impacts on ecosystems and human health. In 2010, an explosion of the Deepwater Horizon (DWH) oil drilling platform resulted in approximately 1,728 km of shoreline oiling. Existing research characterizes health risk from exposure to oil spill chemicals (OSCs) for adults; however, data on impacts to child health are limited. One objective of the Beach Exposure And Child HEalth Study (BEACHES), funded by the Gulf of Mexico Research Initiative, is to estimate health risks to children between walking and six years of age from exposure to OSCs in a post-oil spill scenario …

Measuring Cultural Humility Of Community Health Workers, Nayeema Ahmed

Dissertations and Theses (Open Access)

This study examined cultural humility of community health workers (CHWs) in ambulatory clinical settings. Cultural humility has been defined as an attitude, or process that incorporates openness, power-balance, and critical self-reflection when interacting with people of cultural differences. It differs from the more well-known concept of cultural competence in that cultural humility is not culture specific and reflects provider attitudes and an orientation towards recognizing differences rather than specific knowledge about another culture. As such, cultural humility may lend itself to improving the care process across diverse patient populations. The literature on cultural humility and its relationship with CHWs is …

The Association Between Assorted Hormonal Contraceptive Methods And Advanced-Stage Epithelial Ovarian Cancer: A Systematic Review, Cheng Cheng

Dissertations and Theses (Open Access)

Epithelial ovarian cancer, the most lethal of the gynecological cancers, is typically diagnosed at advanced stages. Women diagnosed with advance-staged (i.e., stage III and IV according to the International Federation of Gynecology and Obstetrics) epithelial ovarian cancer are more likely to have recurrent episodes within 18 months17. According to a 2012 2016 case analysis conducted by the surveillance, epidemiology, and end results, or SEER program, the incidence of ovarian cancer was 11.4 per 100,000 women in all races per year with the highest incidence in non-Hispanic whites, of 11.9 per 100,000 women and the lowest incidence in Asians / Pacific …

Depression, Anxiety, And Social Anxiety As Predictors Of Help – Seeking Behavior Among U.S. University Students, Priya B. Thomas

Dissertations and Theses (Open Access)

Depression and anxiety are the top two mental health issues frequently cited by university students. Furthermore, the majority of students fail to seek professional help and may not find treatment useful. Many studies do not address the multiple factors that inhibit help seeking behaviors. This study aims to examine the associations between mental health issues and specific sociodemographic factors that may predict which students find seeking mental health treatment useful and are likely to seek help for their mental health issues over two semesters. Data from this study can be used to help develop strategies that help students maximize the …

Using S-Predixcan To Identify Associations Of Genetically Determined Gene Expression Levels With Carotid Intima Media Thickness, Andy Bryan A Castaneda

Dissertations and Theses (Open Access)

The aim of the study was to identify associations between predicted gene expression levels using S-PrediXcan and carotid intima media thickness (cIMT) in order to elucidate the etiology of atherosclerosis. Further, we wanted to compare our results to those from a transcriptome wide association study (TWAS) that used actual gene expression levels in whole blood. For our analysis we used summary statistics from a GWAS of cIMT from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium, tissue-specific gene expression profiles from the GTEx project, and S-PrediXcan prediction models. The TWAS of cIMT that we compared our …

Raft-Versus-Host Disease Occurrence Among Cord Blood Transplantation Recipients In Relation To Human Leukocyte Antigen Match Grade, Sarah Chowdhury

Dissertations and Theses (Open Access)

Umbilical cord blood (UCB) transplantation has been consistently found to have low rates of graft-versus-host disease (GVHD), high rates of engraftment, and faster turnaround times in terms of finding suitable donors. In addition, it serves as a viable option for individuals with no matched donor options especially due to its flexible human leukocyte antigen matching criteria. Despite its advantages, there has been an overall decrease in UCB transplantation. However, its advantages emphasize the need for further research and investment in resources such as cord blood banking especially since pediatric populations are most likely to benefit from continued research due to …

Statistical Evaluation Of An Extension Of Linear Discriminant Analysis In Multiclass Settings With An Application For Detection Of Cervical Neoplasia, Frances A. Brito

Dissertations and Theses (Open Access)

Although a pathologists’ review of Papanicolaou smear cell samples has been successful in decreasing cervical cancer incidence, it is often costly and time-consuming. Quantitative cytology is a promising semi-automated method that measures cell features for further analysis or classification. There have been several advancements in classification algorithms, but many do not account for the nested data structure seen in quantitative cytology. Further, histologic diagnoses are separated into five or more classes, yet, multiclass classification has not been investigated. Here, we compare the predictive performance of macrolevel discriminant analysis (MDA) to traditional discriminant analysis methods in multi-class settings on cervical quantitative …

The Health And Wellness Characteristics Of Food And Beverage Service Industry Workers In Austin, Texas: A Participatory Cross-Sectional Survey, Alexandria Abbott

Dissertations and Theses (Open Access)

Food and beverage service industry workers are prone to tobacco use, alcohol abuse, illicit drug use, and mental health conditions. These workers are also highly likely to not have health insurance. Despite the poor health outcomes that stem from these conditions, little to no empirical evidence currently exists to explain the factors that contribute to the poor health condition of the service industry workforce. This study used a cross-sectional online survey to gather preliminary information on the health and wellness condition of service industry workers over the age of 18 in Austin, Texas. Survey respondents revealed high rates of alcohol …

Follow Up Care, Cancer Treatment Summaries And Patient Centered Communication, Ashleigh Gil

Dissertations and Theses (Open Access)

The adolescent and young adult (AYA) age group is the cohort of individuals who have been diagnosed with and/or are survivors of cancer. It is recommended they receive lifelong follow up care to prevent or mitigate late health effects associated with cancer and treatment. However, AYAs are caught between the pediatric and adult healthcare systems and they may not be able to fully advocate for their healthcare needs. Some factors that may be associated with AYAs survivorship care are treatment summaries and where they receive follow up care. This study aimed to identify if receipt of a treatment summary and …

Assessing Patient Attitudes To Ward Genetic Testing For Hereditary Hematologic Malignancy, Addison Johnson

Dissertations and Theses (Open Access)

Since 2003, more than 15 genes have been identified to predispose to hereditary hematologic malignancy (HHM). Although the diagnostic yield of germline analysis for leukemia is similar to solid tumors, referral for genetic evaluation in adults with leukemia is underperformed. Identifying HHM is important for prognostication, treatment, and donor selection for hematopoietic stem cell transplant. No studies have examined leukemia patients’ attitudes toward genetic testing for HHM. This study aimed to assess leukemia patients’ attitudes toward genetic testing and elicit current perceived distress due to a leukemia diagnosis. Data were elicited through an electronic survey sent to 5,513 patients diagnosed …

Demographic Predictors Of Adult Behaviors In The Pediatric Postoperative Environment, Natasha H. Hikita, Amber Osorno, Carlie Taurosa, Michelle A. Fortier, Zeev N. Kain, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

Over 85% of children experience postoperative pain. If poorly treated, pediatric postoperative pain may lead to various negative health outcomes. Adult behaviors may be associated with child experiences in the postoperative environment. For example, adult behaviors such as distraction, humor, and coping advice divert a child’s attention away from their pain and thus, may significantly reduce child postoperative distress. In contrast, adult behaviors such as empathy, reassurance, and apology direct a child’s attention towards their pain which may increase a child’s overall postoperative distress. Moreover, patient demographic factors, like child ethnicity, may significantly alter the frequency of use of these …

Pediatric Postoperative Pain Medication: Child Sex And Ethnicity Interact To Predict Parent Medication Attitudes, Vivian Luong, Harshitha V. Venkatesh, Michelle Fortier, Zeev N. Kain, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

Over 85% of children experience significant pain after surgery. Despite this presence of pain, research suggests that a quarter of these children receive very little or even no pain medication at home. Such poor pain management in children can have harmful long-term consequences, both physically and psychologically. Previous research indicates that the amount of pain medication administered to children in the home may be significantly impacted by beliefs and attitudes parents have regarding analgesics. Given this, the purpose of the present study is to identify which demographic factors are associated with certain parent analgesic attitudes or misconceptions among pediatric patients …

Weight Status As A Moderator Of Low Self-Esteem And Poor Sexual Functioning, Madison Hinkle

Electronic Theses and Dissertations

Researchers have found that self-esteem and weight status can impact numerous aspects of an individual’s life, including reproductive health issues. However, there has been limited research specifically examining how self-esteem may affect female sexual functioning. The current study aims to examine whether self-esteem is a significant predictor of sexual functioning, and whether this relationship may change as a function of women’s weight status. Participants consisted of 730 women ranging from 18 to 49 years of age, who were recruited through an online questionnaire. Results indicate that higher levels of self-esteem predict better sexual functioning and weight status was found to …
