The Relationship Between Social Media Use And Depression In College Students: A Scoping Review, Susan Wu

Dissertations and Theses (Open Access)

Background: In 2017, 17.3 million adults in the U.S. (7.1% of all U.S. adults) have had at least one major depressive episode, with individuals ages 18-25 having the highest prevalence of major depression at 13.1%. Studies have looked at the association between social media (SM) use and depression with mixed findings. The goal of this research is to conduct a scoping review of existing evidence for the relationship between SM use and depression among college students.

Methods: Searches for articles published in the scientific literature were performed on PubMed, Embase and Scopus. Articles selected followed an inclusion criteria: studied SM …

Evaluating The Multivariate Relationship Between Breastfeeding, Early Childhood Obesity, Asthma, And Mental Illness In Dallas, Tx, Sitara Weerakoon

Dissertations and Theses (Open Access)

The aim of this study was to examine the associations between breastfeeding, asthma and mental illness in North Texas children aged two to five years, and to explore whether these associations are explained by the presence of obesity. The study population comprised of 1,174 children whose caregivers responded to a 2015 survey administered by Children’s Health and the Health & Wellness Alliance for Children. Information on breastfeeding, BMI, asthma, and mental illness were self-reported by primary caregivers. Of the 1,174 children, 61% were breastfed, 13% had asthma, and 17% had a mental illness. The odds of having asthma were 2.28 …

Numerical Study For Seamless Clinical Trials With Covariate Adaptive Randomization, Mengxi Wang

Dissertations and Theses (Open Access)

One important goal of the pharmaceutical industry is to evaluate new therapies in a time-sensitive and cost-effective manner without undermining the integrity and validity of clinical trials. Adaptive seamless phase II/III designs (ASD) have gained popularity for accelerating the drug development process and reducing cost. Covariate adaptive randomization (CAR) is the most popular design in randomized controlled trials to ensure valid treatment comparisons by balancing the prognostic characteristics of patients among treatment groups. Although adaptive seamless clinical trials with CAR have been implemented in practice1, the theoretical understanding of such designs is limited. In addition, current approaches to control the …

Long-Term Outcomes After Endovascular Stent Placement For Long-Segment Superficial Femoral Artery Lesions, Nader Zamani

Dissertations and Theses (Open Access)

Objective: Endovascular intervention is commonly pursued as first-line management of symptomatic, long-segment superficial femoral artery (SFA) disease. The relative effectiveness and comparative long-term outcomes among bare metal stents (BMSs), covered stents (CSs), and drug-eluting stents (DESs) for long-segment SFA lesions remain uncertain.

Methods: A retrospective cohort study identified patients with symptomatic SFA lesions measuring at least 15cm who successfully received an endovascular stent (BMS, CS, or DES). The outcomes were patency, patient presentation upon stent occlusion, amputation free survival (AFS), and all-cause mortality. Proportional hazards regressions and a multinomial logistic regression model were used to control for significant confounders.

Results: …

Lymphocyte-Specific Tyrosine Kinase Expression In Ovarian Cancer: A Valuable Prognostic Indicator, Emily Moss Hinchcliff

Dissertations and Theses (Open Access)

Cellular immune response, specifically tumor infiltrating lymphocytes (TILs), has been correlated to survival in epithelial ovarian cancer; however, specific gene expression patterns for this response remain poorly understood. The objective of this research was to investigate the prognostic and biologic significance of immune-related gene expression in high grade serous ovarian cancer (HGSOC). To do so, a panel of immune related gene expression was evaluated in HGSOC utilizing The Cancer Genome Atlas (TCGA) and validated in an independent cohort of ovarian tumors. Based on the strong association with survival, the cohort was grouped into LCK (lymphocyte specific tyrosine kinase) high and …

Clinical Diagnostic Whole Exome Sequencing For Infants In Intensive Care Settings: Outcomes Analysis And Economic Evaluation, Hadley Stevens Smith

Dissertations and Theses (Open Access)

Whole exome sequencing (ES) is an extensive form of genetic testing and increasingly used as a diagnostic tool. Clinical uptake of genome-scale sequencing occurred without clear guidelines for application or robust information regarding potential impact on patient health outcomes or cost of care. For infants in intensive care with suspected genetic conditions, ES can be especially powerful to identify a specific diagnosis and inform crucial decisions about medical care. However, little is known about the cost-effectiveness of ES compared to other diagnostic strategies. This project first assessed the literature on pediatric clinical ES. Then, using electronic medical record, diagnostic laboratory, …

Fire Department Support And Physical Activity Of Volunteer Firefighters: A Cross-Sectional Examination, Sarah Wagner

Dissertations and Theses (Open Access)

Greater health and fitness of volunteer firefighters protects them from cardiovascular disease-related deaths, reduces risk of injury, and improves job performance, which subsequently provides better protection for the majority of the U.S. population who is served by volunteers. Given the strong social support system characteristic of the U.S. fire service, there seems to be potential opportunity to influence the behaviors of firefighters by creating a culture that promotes healthy habits rather than unhealthy. Objective: Determine the association between fire department culture’s encouragement of physical activity and volunteer firefighters’ moderate- to vigorous-intensity aerobic activity. Methods: A cross sectional analysis was performed …

Evaluating The Impact Of Early Initiation Of Antiretroviral Therapy (Art) On Patient Outcomes Among Hiv-Infected Adolescents And Young Adults In Uganda, Hilda Sekabira Nakalema

Dissertations and Theses (Open Access)

Introduction: Since the introduction of anti-retroviral therapy (ART), treatment initiation criteria have continually been revised to start these lifesaving drugs before onset of advanced disease and optimize ART benefits for people living with HIV. However, little is known about the effect of these changes on treatment outcomes among young people. We evaluated the effect of such a policy change on long term adherence and treatment outcomes among young people, aged 15-24 years.

Methods: We conducted a retrospective cohort analysis of young people, 15-24years old, who started ART from January 2012 – December 2016. We used administrative data from the District …

Ends Device Types And Subsequent Use Of Combustible Tobacco Products Among Texas Youth, Aslesha Sumbe

Dissertations and Theses (Open Access)

The aims of the study were to determine whether ENDS device types (i.e., disposable devices, replaceable cartridges, and refillables) at initial, or first ENDS use is longitudinally associated with subsequent initiation of combustible tobacco products (cigarettes, hookah, cigars) and continued, past 30-day use of combustible and ENDS products. This study is a secondary analysis of data from the Texas Adolescent Tobacco and Marketing Surveillance system (TATAMS) study, a longitudinal cohort study of students who were in the 6th, 8th, and 10th grades (n = 3907) during the 2014-2015 academic year. Data were collected every 6 months, from 2014-2018. Using data …

Dynamic Competing Risk Model For Multi-Type Recurrent Events With Dependent Termination, Alokananda Ghosh

Dissertations and Theses (Open Access)

Cardiovascular disease (CVD), defined by the World Health Organization (WHO) as diseases that involve the heart and/or blood vessels is the number one cause of morbidity and mortality worldwide. In the United States more health care dollars are spent managing and treating CVD and/or its complications than any other disease process. Coronary heart disease (CHD) is the leading cause of deaths (43.8%) attributable to CVD, followed by stroke (16.8%), hypertension (9.4%) and heart failure (HF) (9%). CVD-related deaths and attendant morbidities, which include lifelong disability are in many cases preventable. This research proposes a dynamic risk model that handles multi-type …

Healthy Life Choice: Using The School-Based Program To Facilitate Change, Jennifer Shaheed

Doctor of Psychology (PsyD)

Research highlights the multiple determinants of weight including poverty, nutrition, and physical activity (Miguel-Berges, 2018). Children and adolescents living in rural areas are at greater risk than their urban counterparts. Regarding physical activity, there are often fewer recreational resources and the high poverty rate precludes transportation or additional fees associated with many extracurricular activities. In response to this problem, research has shown the educational environment is a point of access to reinforce health education and behavior. One evidenced-based program showing significant outcome in improving health behavior is the Healthy Lifestyle Choices (HLC) which is designed to be delivered in an …

Pyschosocial Well-Being And Efforts To Quit Smoking In Pregnant Women Of South-Central Appalachia, Brittney Stubbs

Undergraduate Honors Theses

A sample of 1,031 pregnant women from five prenatal practices participated in Tennessee Intervention for Pregnant Smokers (TIPS), an expanded 5A’s (Ask, Advise, Assess, Assist, Arrange) program. Stress, self-esteem, depressive symptoms, and disordered eating were hypothesized to differ among three groups: pregnant women who never smoked, pregnant women who smoked but quit prior to birth, and pregnant women who smoked and did not quit prior to birth. Smokers who quit were lower in stress and higher in self-esteem than those who did not quit. Non-smokers were lowest in stress and depression, and highest in self-esteem. These findings may lead to …

Coercive And Deceptive Predictors Of Sexual Risk: The Moderating Role Of Self-Esteem, Morgan Barker

Undergraduate Honors Theses

Risky sexual practices can lead to concerning public health issues, including sexually transmitted infections (STIs) and unintended pregnancy. Coercive or deceptive behaviors by one’s partner to engage in risky practices may be one factor contributing to sexual risk. This study examined experiences of sexual risk coercion and deception, including partner sexual infidelity, coerced condom nonuse, and fear of negative partner reaction to condom request, as predictors of engagement in sexual risk behaviors, including condom use, safer sex communication, and lifetime number of sexual partners. Self-esteem was examined as a moderator. College students (N = 216) were recruited through the …

Risk-Taking, Thinking Styles, And Criminality: A Fuzzy-Trace Theory Perspective, Adrienne Machann

Electronic Theses and Dissertations

Preferred modes of thinking, otherwise known as biases, have been well documented in adult reasoning and decision-making (Evans, 2003; Gilovich, Griffin, & Kahneman, 2002; Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). Researchers have explained these biases by proposing that the basis for them is a system of thought that relies mostly on intuition and “gut feelings” rather than logical analysis of the situation (Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). According to standard dual-process theories, intuition is described as a thought process so quick, it is automatic and, at times unconscious; conversely, analytical thinking is slow and steady, …

Health And Quality Of Life Of Children Undergoing Elective Surgery, Vivian Luong

Student Scholar Symposium Abstracts and Posters

Multiple studies have found that poorer health is associated with significantly lower quality of life when comparing children and adults with health conditions such as cancer, diabetes, asthma, and ADHD to their normal healthy counterparts. The relationship between health and quality of life, however, has yet to be examined in children who have undergone elective surgery. More than 5 million children in the U.S. undergo surgery each year. These children are often undergoing surgery for a number of health issues that may impede quality of life. Consequently, this study analyzes the effects of health on the quality of life of …

Female Genital Mutilation In The United States: Estimating The Number Of Girls At Risk, Phyllis Chesler

Dignity: A Journal of Analysis of Exploitation and Violence

Female genital mutilation (FGM) destroys the capacity of women to experience sexual pleasure. It causes serious medical complications such as bleeding, painful urination, cysts, dangerous and recurrent bladder and urinary tract infections, the growth of scar tissue that make marital intercourse a nightmare and that turns childbirth into an experience of danger and torture. Due to immigration, FGM now poses a potential health crisis in the West, both in Europe and in the United States. To estimate how many girls who live in the West are at risk, one can measure the prevalence of FGM in the non-Western countries where …

Relational Processes In Support-Related Communication Among Young Adults With Cancer, Kathleen Darabos

Dissertations, Theses, and Capstone Projects

Despite decades of studies reporting positive associations of social support with cancer-related quality of life, little attention has been paid to understanding how relational qualities (e.g., self-disclosure, perceived support member disclosure, perceived support member responsiveness) of cancer-related support exchanges might influence psychological adjustment and intimacy among young adults with cancer. Further, little attention has been paid to understanding how young adults with cancer communicate with their social support networks among different modes of communication [(face-to-face vs. technology-related (e.g., text message, social media)] remains poorly understood. Questionnaire data from 45 young adults with cancer combines these two separate but related literatures …

Assessing Hospitalizations Due To Assaults At Dell Seton Medical Center (2015-2018), Stephani L. Curry

Dissertations and Theses (Open Access)

Physical assaults are a major public health concern in the United States, with rates being on the rise during the last couple of years (WISQARS Nonfatal Injury Reports, n.d.). In Austin at the Dell Seton Medical Center [DSMC], physical assaults are a main reason for hospitalization, making up nearly 10% of their hospitalizations, with around 250 patients per year. No subgroup of the population is risk free from physical assaults; however, national data suggest some sociodemographic groups are at higher risk than others (“Injury and Violence Prevention”, n.d.). Given the diversity of Austin, TX, it was unclear whether local sociodemographic …

The Association Of Cell Phones With Adolescents' Academic Performance, Sleep, Time Spent With Friends, And Cyberbullying Exposure, Johanna E. Peyton

Dissertations and Theses (Open Access)

This study examined the association between owning or having access to a cell phone with/without internet access and adolescent academic performance, whether they met the guidelines for recommended nightly sleep, the amount of time spent with friends outside of school and the presence and frequency of cyberbullying experienced by 8th and 11th grade participants in the 2015-2016 SPAN study in Texas. This study also examined the association between gender of the adolescent and the above-mentioned outcomes.

The study group consisted of 5,421 adolescents from 8th grade and 3,635 from 11th grade. The 8th grade sample contained 51.48% males(48.6% females) and …

Exploring Prenatal Risk Factors Among Hispanic Children With Autism Spectrum Disorders. – A Pilot Study In The Rio Grande Valley, Lauren Tien

Dissertations and Theses (Open Access)

Background: Peer-reviewed studies suggest that a hostile gestational environment is associated with delayed neurological development in infants. Autism spectrum disorder (ASD) is estimated to affect 1 in 59 children in the United States; however, few studies have specifically investigated risk factors for autism in Hispanic children. Purpose: The University of Texas RGV Hispanic Autism Research Center (HARC) studied Hispanic children with ASD and their biological mothers to identify potential environmental exposures and prenatal risk factors that could impact the risk for ASD through preliminary research in the Rio Grande Valley. Methods: This pilot study recruited 25 Hispanic mothers and their …
