Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes

Electronic Theses and Dissertations

Opioid use disorder (OUD) impacts 5.6 million people in the US. Buprenorphine (BUP) is a commonly prescribed opioid medication used to treat OUD, including in pregnant women. However, opioid use during pregnancy is associated with poorer infant outcomes including reduced fetal growth, neurodevelopmental deficits, and neonatal opioid withdrawal syndrome (NOWS). Recent clinical data suggests that providing mothers with a lower dose of BUP may result in fewer negative outcomes in infants. Here, a preclinical rodent model of low-dose perinatal BUP exposure was used to study offspring health outcomes in the neonate, juvenile, and adolescent offspring. Dams were given clinically relevant …

Seeds In The City: Impacts Of Urbanization On Avian Seed Dispersal Networks In The Southern Appalachians, Jody Horton

Electronic Theses and Dissertations

Urbanization is an intensive form of habitat disturbance associated with detrimental effects on biodiversity. However, few studies have investigated its effects on the number, identity and structure of species interactions while considering seasonal fluctuations in communities. Avian seed dispersal is a vital ecosystem service, and the interplay of urbanization and seasonality may impact seed dispersal in ways not predicted by either factor alone. In this study, we evaluate the effects of urbanization and season on avian seed dispersal networks in the southern Appalachians. We found that the number and richness of interactions was unaffected, but the identity of interacting bird …

Psychological Mediation Of Minority Stress And Health: Exploration Of Risk Factors In Lgbq College Students, Kyndal Grammer

Electronic Theses and Dissertations

Decades of research have documented pervasive physical and mental health disparities among individuals holding a marginalized identity, including those who identify as lesbian, gay, bisexual, or queer (LGBQ). Heterosexism in the forms of harassment, rejection, and discrimination likely increases minority stress, which is theorized to contribute to documented health disparities. One group that may be particularly vulnerable to effects of heterosexist discrimination, harassment, and rejection is LGBQ college students, especially those who identify as first-generation and were raised in rural environments. The current study aimed to evaluate relationships between LGBQ discrimination, depression, and physical health outcomes at the bivariate level, …

Symptom Clusters In Individuals Seeking Treatment For Gambling Disorder, Blaine Stiglets

Electronic Theses and Dissertations

The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) presents the criteria for Gambling Disorder (GD) as a unidimensional construct where each additional symptom corresponds to increased severity. Many individuals experience addiction symptoms in specific symptom clusters, with membership to one profile of symptoms or other better-representing disorder severity than raw symptom counts. This study explored whether similarly informative symptom clusters exist among adults seeking treatment for gambling harms. The sample included 444 adults (Mage= 44.95) who completed an assessment of DSM criteria for GD at intake. Through a latent class analysis of GD criteria, three …

Do Emotion Dysregulation And Internalized Shame Mediate The Relationship Between Borderline Personality Disorder Symptomology And Criminal Involvement?, Madison Smith

Electronic Theses and Dissertations

Borderline personality disorder (BPD) is a severe and debilitating mental disorder that is over-represented within the criminal legal system (CLS), with 15-29.5% of individuals in the CLS meeting criteria. However, little research has examined mechanisms leading to criminal involvement within this population. Potential mechanisms include positive/negative emotion dysregulation and internalized shame, which (aside from positive emotion dysregulation) have been linked to criminal involvement in other populations. Research has yet to examine these constructs as mechanisms explaining criminal involvement among individuals with BPD. This study examined positive/negative emotion dysregulation and internalized shame as mechanisms of the relationship between BPD and criminal …

Preliminary Evidence For The Validity And Reliability Of A Modified Adverse Childhood Experiences (Aces) Scale: The Variability In Aces Scale, Mary Jo Hedrick

Electronic Theses and Dissertations

Adverse Childhood Experiences (ACEs) research has proliferated in the last twenty years with significant research demonstrating the detrimental effects of early childhood adversity. While many measures purport to measure ACEs, very few capture the intensity of ACEs while still calculating the traditional “ACEs tally.” Thus, it is the goal of this dissertation to collect evidence for an expanded ACES measure. The Variability in Adverse Childhood Experiences Scale (VACE) measure builds upon the original ACEs and captures interval level data. Two survey-based studies were conducted in which convergent and criterion related validity and test-retest reliability evidence were collected. In …

Validation Of A Novel Heritable Rodent Model Of Drug Abuse Vulnerability In Psychosis And Investigation Of Therapeutic Targets, Loren D. Peeters

Electronic Theses and Dissertations

Schizophrenia is a severe neuropsychiatric disorder of largely unknown etiology that is often accompanied by high rates of cigarette smoking, reduced quit success, and high relapse rates. Dysregulated dopamine signaling and aberrant synaptic plasticity in the mesocorticolimbic pathway are implicated in the pathophysiology of schizophrenia and conferred substance abuse disorder and relapse vulnerability. Genetic factors are presumed to play a significant role in the development of schizophrenia, with a 40-50% concordance rate for monozygotic twins, although genetic markers are inconsistent. As such, epigenetic factors have instead been implicated. Specifically, there is strong evidence to suggest DNA methylation at several candidate …
