Sustaining Breaths For Restorative Rest: A Preliminary Evaluation Of Sleep, Mental Health, And Cognitive Function Following Hypoglossal Nerve Stimulation For Obstructive Sleep Apnea, Elliottnell Perez

Theses and Dissertations

Introduction: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that produces repetitive obstruction or collapse of the upper airway. Positive airway pressure (PAP) therapy is the gold standard treatment for OSA. Hypoglossal nerve stimulation (HNS) is considered an alternative treatment for patients who are unable to tolerate PAP therapy. The purpose of the study was to examine sleep, mental health, and cognitive health outcomes before and after HNS to determine its viability as an alternative treatment.

Methods: The study utilized a single-group, pretest-posttest design. Objective and subjective sleep was measured using actigraphy, sleep diary, and questionnaires. Objective and subjective …

Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox

Theses and Dissertations

Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (M_age = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …

The Harm In Seeking Care: Assessing The Relationship Between Healthcare Discrimination And Healthcare Avoidance Behaviors In The Past Year And Since The Start Of The Coronavirus Pandemic In A Transgender And Gender Independent Sample, Kyle L. Mason

Theses and Dissertations

Background: Gender minorities encounter a myriad of barriers to accessing general and gender affirming healthcare. Financial disparities impacting affordability of healthcare costs and insurance-based denials for gender-affirming care are among prominent barriers discussed. Considerations of the prevalence of stigma, discrimination, and erasure of gender minority identities must not be neglected when seeking to understand healthcare accessibility and utilization in this population. Previous researchers have examined gender minority patients’ experiences of discrimination in healthcare settings and delaying care due to fear of discrimination. There is a dearth of knowledge about the relationship between lifetime exposure to varied forms of healthcare discrimination …

The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan

Theses and Dissertations

Background: Postpartum depression (PPD) is a phenomenon that affects nearly 10-15% of pregnancies in the US. It is characterized by depressed mood or anhedonia and lasting for more than 2 weeks. PPD changes how moms interact with family members and child-rearing behavior. Depression is a phenomenon that is also known to affect the psychopathology of children. However, the specifics of how postpartum depression impacts children remains controversial. Many studies do not control for major depressive disorder which makes it difficult to disentangle the impact depression has within the first year of life. Furthermore, other PPD risk factors may be confounding …

Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt

Theses and Dissertations

Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …

Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers

Theses and Dissertations

Anxiety disorders (ADs) and stress-related disorders are some of the most common psychiatric disorders in the United States. Like other c0mplex psychiatric illness, genetics and neuroimaging research has focused on understanding their underlying neurobiology. Areas within the fear-network play important roles in threat perception, fear conditioning/learning, cognitive processing, and modulation of fear responses including contextual modulation and extinction and have been implicated in ADs as well as stress disorders such as posttraumatic stress disorder (PTSD). The primary gap in the current search for underlying biological mechanisms is in whether biomarkers associated with disorders share genetic influences with the disorders they …

Penalized Mixed-Effects Ordinal Response Models For High-Dimensional Genomic Data In Twins And Families, Amanda E. Gentry

Theses and Dissertations

The Brisbane Longitudinal Twin Study (BLTS) was being conducted in Australia and was funded by the US National Institute on Drug Abuse (NIDA). Adolescent twins were sampled as a part of this study and surveyed about their substance use as part of the Pathways to Cannabis Use, Abuse and Dependence project. The methods developed in this dissertation were designed for the purpose of analyzing a subset of the Pathways data that includes demographics, cannabis use metrics, personality measures, and imputed genotypes (SNPs) for 493 complete twin pairs (986 subjects.) The primary goal was to determine what combination of SNPs and …

Chronic Pain Causal Attributions In An Interdisciplinary Primary Care Clinic: Patient-Provider And Provider-Provider Discrepancies, Bryan Jensen

Theses and Dissertations

The purpose of the present study was to investigate the influence of pain causal attributions on patient pain-related functioning, treatment engagement, and clinical outcomes. Additionally, the impact of discordant pain causal attributions between patients and their providers as well as between interdisciplinary providers was examined. Patients rated their pain functioning and causal pain attributions during a regular clinic visit. Following the patient’s visit both the behavioral medicine provider and internal medicine resident provided ratings of similar pain-related functioning domains and causal attributions. Follow-up data were collected from the electronic medical record three months following that clinic visit. Overall, results revealed …
