Exploration Into The Relationship Between Colitis And Depression: A Potential Role For The Aryl Hydrocarbon Receptor, Kasie Lynn Roark Apr 2023

Exploration Into The Relationship Between Colitis And Depression: A Potential Role For The Aryl Hydrocarbon Receptor, Kasie Lynn Roark

Theses and Dissertations

Inflammatory Bowel Disease (IBD) is a group of chronic gastrointestinal disorders with unclear etiology comprised of two defined disorders – Crohn’s Disease (CD) and Ulcerative Colitis (UC). IBD leads to chronic pain, socially isolating symptoms, and an overall reduction in patient quality of life. There is currently no cure for IBD. Due to decreased mucous production and weakening of the colonic epithelial lining, gut-microbiota and their metabolites can invade the intestinal lamina propria and circulate systemically, a term known as “leaky gut”. Recent studies show a relationship exists between peripheral inflammation, such as IBD, and depression. The gut-brain axis (GBA) …

The Intergenerational Effects Of Adverse Childhood Experiences On Children’S Emergency Department Utilization And Depression And Anxiety In South Carolina, Eboni E. Haynes

Theses and Dissertations

Adult exposure to adverse childhood experiences (ACEs) is common in the U.S., with over half of adults reporting exposure to at least one ACE. Childhood trauma is associated with risk factors for premature death, disability, poor physical and mental health, and lower quality of life in adults. Traumatic experiences also influence parenting behaviors later in life, placing offspring at an increased risk of ACE exposure. Few studies have explored the intergenerational effects of ACEs on the health and well-being of offspring. This study sought to identify whether associations existed between caregiver ACE exposures and emergency department (ED) utilization for sick …


Role Of Heart Rate Variability Biofeedback In Cognitive Performance, Chronic Pain, And Related Symptoms, James P. Winstead Jul 2019

Role Of Heart Rate Variability Biofeedback In Cognitive Performance, Chronic Pain, And Related Symptoms, James P. Winstead

Theses and Dissertations

Over-modulation of the sympathetic nervous system and reduced heart rate variability (HRV) are commonly overlooked components of pain, poor cognition (decreased attention, recall, and cognitive processing), depression, stress, and fatigue. HRV Biofeedback (HRVB) training induces HRV coherence to balance the autonomic system. Paced breathing (~6 breaths/minute) increases HRV coherence. This randomized, controlled intervention trial tested the hypothesis that HRVB would improve HRV coherence, pain (severity, interference, and catastrophizing), cognitive performance, and reduce depressive, stress, and fatigue symptoms and pain medication use in veterans. Participants were randomized to previously established HRVB or control protocols. Each participant completed a Baseline Assessment, 6 …


Interdependent Mechanisms Of Stress Susceptibility, Julie Elaine Finnell Jul 2019

Interdependent Mechanisms Of Stress Susceptibility, Julie Elaine Finnell

Theses and Dissertations

Social stress is a significant risk factor for the emergence of psychiatric disorders including depression and anxiety. While there are a number of commercially available therapeutic options for the treatment of these disorders, these treatments require weeks of continuous use to produce behavioral efficacy. It has also been suggested that these traditional therapies are only marginally effective in producing complete remission, suggesting that our understanding as it pertains to the mechanisms underlying stressinduced behavioral dysfunction is still in its infancy. In the last few years, inflammation has become a major focus in the field of stress and depression as clinical …

Implementation Of A Depression Screening Tool For Cardiovascular Patients In The Primary Care Setting, Amber Nicole Ballentine Jan 2018

Implementation Of A Depression Screening Tool For Cardiovascular Patients In The Primary Care Setting, Amber Nicole Ballentine

Theses and Dissertations

Background: Patients with cardiovascular disease (CVD) have a two-fold increased risk of depression as compared to patients without CVD. According to the American Heart Association (AHA, 2016), there is no gold-standard procedure for screening for depression in cardiovascular patients. Screening for depression varies greatly across specialties and practices, often leaving a gap for detection and treatment of depression in cardiac patients. There are many depression screening tools available; however, the AHA recommends use of the patient health questionnaire (PHQ) screening tool. The PHQ-2 and PHQ-9 questionnaires are the most brief, sensitive, and specific depression screening tool for patients with …

The Effect Of Depression And Antidepressants On Cost, Survival And Adherence To Hormone Therapy In Breast Cancer, Virginia Noxon Jun 2016

The Effect Of Depression And Antidepressants On Cost, Survival And Adherence To Hormone Therapy In Breast Cancer, Virginia Noxon

Theses and Dissertations

Introduction: Breast cancer patients with a depression diagnosis before or after cancer diagnosis have increased cost, shorter survival time and reduced adherence to hormone therapy. Treating depression in these patients should improve these outcomes; however, there is scarce literature on this topic. Currently, no study has determined the association of concurrent depression while adjusting for a history of depression or treating depression with antidepressants with cost, survival and adherence to hormone therapy. This study has two objectives: 1) to determine the association of concurrent depression with cost, survival and adherence to hormone therapy adjusting for a history of depression 2) …

Depression Among Pregnant Latinas In South Carolina, Andrew Fogner

Theses and Dissertations

The aim of the study was to determine the prevalence of depression among pregnant Latinas. To bring to light the importance of prenatal depression prevention, we assessed the effect of the quality of healthcare providers among South Carolina Latinas (n=171). Women answered a validated CES-D and were categorized as depressed (score >16). In multivariate analyses, good perception of quality of healthcare was more likely among women who were not depressed; adjusted odds ratio of 0.75, 95% confidence interval 0.37 – 1.55. The findings show the need for tailoring healthcare to Latinas with prenatal depression prevention. It is imperative to understand …

Pathways To Sexual Risk Taking Among Female Adolescent Detainees, Vera Lopez, Albert M. Kopak, Alyssa G. Robillard, Mary Rogers Gillmore, Rhonda Conerly Holliday, Ronald L. Braithwaite

Faculty Publications

Sexual risk taking among female delinquents represents a significant public health problem. Research is needed to understand the pathways leading to sexual risk taking among this population. This study sought to address this issue by identifying and testing two pathways from child maltreatment to non-condom use among 329 White and 484 African American female adolescent detainees: a relational pathway and a substance use coping pathway. The relational pathway indicated that child maltreatment would be related to non-condom use via depressive self-concept and condom use self-efficacy. The substance use coping pathway suggested that depressive self-concept and alcohol-based expectancies for sexual enhancement …

Criterion Validity Of The Pittsburgh Sleep Quality Index: Investigation In A Non-Clinical Sample, Michael A. Grandner, Daniel F. Kripke, In-Young Yoon, Shawn D. Youngstedt

Faculty Publications

The objective of this study was to investigate the reliability and validity of the Pittsburgh Sleep Quality Index (PSQI) in a non-clinical sample consisting of younger and older adults. There has been little research validating the PSQI with respect to multinight recording as with actigraphy, and more validation is needed in samples not specifically selected for clinical disturbance. Also, the degree to which the PSQI scores may reflect depressive symptoms versus actual sleep disturbance remains unclear. One-hundred and twelve volunteers (53 younger and 59 older) were screened for their ability to perform treadmill exercises; inclusion was not based on sleep …
