‘Things That You Can’T Really Suppress’: Adverse Childhood Experiences In The Narratives Of People With Opioid Use Disorder, Sydney Silverstein, Josef Rivera, Danielle Gainer, Raminta Daniulaityte

Psychiatry Faculty Publications

While numerous studies have established relationships between Adverse Childhood Experiences (ACEs) and adult substance use, few qualitative studies have explored the differing ways in which experiences of childhood adversity are emplotted into narratives of drug use and recovery. This paper analyzes qualitative data collected as part of a mixed-methods longitudinal study of people with opioid use disorder. Narratives of adverse childhood experiences emerged unprompted. After coding qualitative data for mention of ACEs, we thematically analyzed coded data using a framework of critical phenomenology and constructed a four-part typology to differentiate the ways that ACEs were emplotted into narratives. Our …

Alcohol use disorder (AUD) produces cognitive deficits, indicating a shift in prefrontal cortex (PFC) function. PFC glutamate neurotransmission is mostly mediated by α-amino-3‑hydroxy-5-methyl-4-isoxazolepropionic acid-type ionotropic receptors (AMPARs); however preclinical studies have mostly focused on other receptor subtypes. Here we examined the impact of early withdrawal from chronic ethanol on AMPAR function in the mouse medial PFC (mPFC). Dependent male C57BL/6J mice were generated using the chronic intermittent ethanol vapor-two bottle choice (CIE-2BC) paradigm. Non-dependent mice had access to water and ethanol bottles but did not receive ethanol vapor. Naïve mice had no ethanol exposure. We used patch-clamp electrophysiology to measure …

The connection between experiencing trauma and the development of substance use disorder is widely recognized. Although trauma is more prevalent among individuals with substance use disorders, healthcare professionals have limited access to training focused on trauma informed care. It is crucial for those working in addiction treatment to receive training and education on trauma informed care to understand the impact of trauma and its association with substance use disorders.

This DNP project's objective was to develop and evaluate an educational presentation for staff emphasizing the importance of trauma-informed care in the context of addiction. The effectiveness of this intervention was …


The Pornography Industry's Disinformation Campaign On Addiction Recovery Resources, Darryl Mead Oct 2023

The Pornography Industry's Disinformation Campaign On Addiction Recovery Resources, Darryl Mead

Dignity: A Journal of Analysis of Exploitation and Violence

As pornography became increasingly popular online, many unsuspecting consumers reported adverse effects. These included sexual dysfunctions, such as lack of response with real partners, delayed ejaculation, erectile difficulties, and sexual compulsivity. Some pornography consumers began congregating in online self-help portals (forums and websites) to assist one another in quitting or reducing problematic pornography use. The popularity of the self-help resources and their potential to dampen the profits of a lucrative industry resulted in disinformation campaigns run by individuals connected to the pornography industry. In this article, I examine how a paper containing significant inaccuracies about the people organising the online …

Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng Aug 2023

Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng

Electronic Thesis and Dissertation Repository

Nicotine dependence is causally linked to increased risk of mood/anxiety disorders in later life. Females are reported to experience a higher prevalence of anxiety/depressive disorders and challenges in smoking cessation therapies, suggesting a potential sex-specific response to nicotine exposure and mood/anxiety disorder risk. However, pre-clinical evidence of sex-specific responses to adolescent nicotine exposure is unclear. Thus, to determine any sex differences in anxiety/depressive-related outcomes, adolescent male and female Sprague Dawley rats received nicotine (0.4 mg/kg; 3x daily) or saline injections for 10 consecutive days, followed by behavioural testing, in-vivo electrophysiology and Western Blot analyses. Our results revealed that adolescent nicotine …

The purpose of this research study is to explore the lived experience of using opiates, as described by young adults aged 18 to 25 years. Over the last 2 decades, opioid use disorders (OUDs) and opiate overdose deaths have increased dramatically in the United States. What used to be a problem primarily contained to minority groups in poor inner-city areas is now increasingly common in all races, genders, ages, and classes. There has also been an alarming increase in opiate use—including fentanyl, both legal and illegal—among young adults. While much of the literature has been focused on the opiate use …


Side-Stepping God: How The Nonreligious Find Success In Alcoholics Anonymous, Caitlin Trombley Jun 2023

Side-Stepping God: How The Nonreligious Find Success In Alcoholics Anonymous, Caitlin Trombley

Dissertations

This dissertation utilized mixed methods research to examine how nonreligious individuals with substance use disorders navigate recovery within—or in spite of—Alcoholics Anonymous (AA). Both the 12-step program itself and Alcoholics Anonymous have long been criticized for being religious and/or spiritual in nature, and some studies have shown that this is particularly challenging for nonreligious individuals seeking recovery. The purpose of this research was to (a) identify differences in recovery resources (recovery capital) between the religious, the nonreligious, those in AA, and those who have adopted alternative forms of recovery; (b) identify barriers that the nonreligious face as they navigate recovery …

Master's Projects and Capstones

Problem: The use of evidence-based alternative forms of therapy like horticulture therapy and therapeutic gardening is underutilized in substance use recovery programs in the United States. As the country continues to struggle with addiction, it is important that recovery programs look to and incorporate these alternative therapies into official curricula. Currently, 46.3 million individuals living in the United States are living with a substance use disorder (U.S Department of Health and Human Services’ Substance Abuse and Mental Health Services Administration, 2022).

Context: The intervention was implemented at an all-male substance use treatment facility in San Jose, CA that houses up …


The Impact Of Chronic Morphine Exposure On The Intrinsic Electrical Properties Of Orexin Neurons, Elizabeth Berry May 2023

The Impact Of Chronic Morphine Exposure On The Intrinsic Electrical Properties Of Orexin Neurons, Elizabeth Berry

NYMC Student Theses and Dissertations

Addiction to drugs of abuse is a growing problem in today’s society and current treatments often fail to adequately manage the negative withdrawal symptoms that drive relapse. Therefore, development of more effective therapies is a high priority. The orexin neuropeptide system is a key regulator of reward processes and is therefore an attractive therapeutic target. However, the precise impact of chronic drug exposure on orexin neuron function remains largely unknown. Data from a recent publication found that human post-mortem brains from opiate users have smaller but more numerous orexin immunoreactive neurons. Since decreased neuronal soma area suggests increased excitability, we …

Assessing The Involvement Of Projections From The Prelimbic Prefrontal Cortex To The Paraventricular Nucleus Of The Thalamus In Cocaine Withdrawal-Induced Anxiety, Clinton Coelho Apr 2023

Assessing The Involvement Of Projections From The Prelimbic Prefrontal Cortex To The Paraventricular Nucleus Of The Thalamus In Cocaine Withdrawal-Induced Anxiety, Clinton Coelho

MUSC Theses and Dissertations

Withdrawal from cocaine induces an immediate and powerful negative affective state which is characterized by feelings of agitation and anxiety in humans and anxiety-like behaviors in rodents. It has been hypothesized that the anxiogenic effects associated with cocaine withdrawal play a major role in continued cocaine use and drive relapse to cocaine seeking. The prelimbic (PL) medial prefrontal cortex is not only involved in the processing and regulation of negative emotions such as anxiety but also mediates relapse to cocaine-seeking. Subcortical hubs of the reward system that receive projections from the PL neurons are known to be dysregulated during different …

Computational Design And Molecular Modeling Of Morphine Derivatives For Preferential Binding In Inflamed Tissue, Makena Augenstein, Nayiri Alexander, Matthew Gartner

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The opioid epidemic has impacted over 10 million Americans in 2019. Opioids, like morphine, bind non-selectively in both peripheral tissue, leading to effective pain relief, and central tissue, resulting in dangerous side effects and addiction. The inflamed conditions of injured tissues have a lower pH (pH = 6–6.5) environment than healthy tissue (pH = 7.4). We aim to design a morphine derivative that binds selectively within inflamed tissue using molecular extension and dissection techniques. Morphine binds to the μ-opioid receptor (MOR) when the biochemically active amine group is protonated. Fluorination of a β-carbon from the tertiary amine group led to …


Extending Immunity For Drug Overdoses, Dixie R. Tabet, Maggie G. Spadaro, Kaylie E. Moss Apr 2023

Extending Immunity For Drug Overdoses, Dixie R. Tabet, Maggie G. Spadaro, Kaylie E. Moss

Belmont University Research Symposium (BURS)

The Tennessee Code 63-1-156 provides immunity to those who suffer from a drug overdose that seek medical assistance, only for the first overdose. After the first overdose, individuals who seek medical assistance do not receive immunity and are subject to criminal charges. Over the past 5 years, drug overdose deaths have increased significantly and in 2021 3,814 Tennesseans died from a drug overdose. In addition, individuals incarcerated for drug-related offenses make up about 20% of the state’s prison population. The state of Tennessee has had a significant increase in drug abuse rates, leading to a rise in overdose deaths and …


Role Of Nucleus Accumbens Dopamine Receptor Signaling In The Suppression Of Punished Reward Seeking, Grace M. Joyner, Anna Caroline Toburen Apr 2023

Role Of Nucleus Accumbens Dopamine Receptor Signaling In The Suppression Of Punished Reward Seeking, Grace M. Joyner, Anna Caroline Toburen

Senior Theses

Previous studies have shown that within the nucleus accumbens (NAc), a brain region associated with motivation and reinforcement learning, activity of neurons expressing the dopamine D2 receptor (D2R neurons) act as a “break” on risky behavior associated with negative outcomes. Moreover, when these neurons are stimulated, rats were found to become more risk averse. However, the impact of dopamine signaling through NAc D2R neurons in risk avoidance is still unclear. To further explore the role of NAc dopamine signaling in punished reward-seeking, we tested rats in a novel punished food-seeking paradigm in which subjects are trained to choose between a …

Lived Experiences Of People With Substance Use Disorder As Healthcare Education To Develop Empathy For This Population, Whitney Bynum Jan 2023

Lived Experiences Of People With Substance Use Disorder As Healthcare Education To Develop Empathy For This Population, Whitney Bynum

Nursing | Student Research Posters

Stigmas that develop among healthcare workers regarding patients with substance use disorder include: "drug-seeking", "violent", and "unmotivated". These beliefs can decrease the quality of care provided and results in less people seeking out needed treatment. Healthy People's 2030 goals include reducing drug and alcohol addiction. In order to do this, healthcare workers need to show empathy and form trusting relationships with this patient population. Building a trusting relationship allows the patient to be more receptive to help and suggestions. Learning the life story of a patient can help healthcare workers develop empathy and reduce negative attitudes.


Prescription Opioid Misuse And Addiction: Healthcare’S Contribution To The Opioid Epidemic And What Can Be Done About It, Emily Larsen, Katrina Ecke Jan 2023

Prescription Opioid Misuse And Addiction: Healthcare’S Contribution To The Opioid Epidemic And What Can Be Done About It, Emily Larsen, Katrina Ecke

Nursing | Senior Theses

Up to one in four patients undergoing prolonged opioid therapy in a primary care setting battle opioid addiction. In 2020, the CDC found that more than 16,000 deaths involving prescription opioids (limited to natural and semi-synthetic opioids and methadone) had occurred, which is equivalent to about 45 deaths per day. Opioid overdose death can be identified through three distinct waves; increased prescribing of opioids in the 1990’s began the first wave, the beginning of the second wave came in 2010 with a rapid increase in heroin related overdose deaths, and in 2013 the third wave began with a significant increase …

A Tale Of Two Waves: The Role Of Genomic Enhancers In Regulating Transcriptional And Epigenetic Responses To Neuronal Activitiy, Robert A. Phillips Iii Jan 2023

A Tale Of Two Waves: The Role Of Genomic Enhancers In Regulating Transcriptional And Epigenetic Responses To Neuronal Activitiy, Robert A. Phillips Iii

All ETDs from UAB

The mesolimbic dopamine (DA) pathway, which consists of dopaminergic neurons that project from the ventral tegmental area (VTA) to the nucleus accumbens (NAc), is heavily implicated in drug addiction. Exposure to drugs of abuse results in increases in extracellular concentrations of DA in the NAc, which in turn activates an immediate early gene (IEG) expression program that primarily consists of activity-dependent transcription factors, such as the AP1 subunits Fos and JunB. IEGs engage a set of temporally and functionally distinct genes, termed the late response gene (LRG) expression program. While gene expression changes are critical for drug-dependent adaptations, two major …
