Social Rejection, Isolation, And Substance Use Disorders: A Neurobiological Defense Of Social Network Intervention In Single-Site Housing First, Victoria Eichel

Scripps Senior Theses

Abstract

Introduction: Rising rates of homelessness in the United States demand not only increased housing efforts but also comprehensive strategies addressing the underlying causes of chronic homelessness. Among the most prevalent factors is substance use disorder (SUD), which both contributes to and results from housing instability. Conventional abstinence-based treatment models often fail to address the root causes of substance use, particularly the chronic social isolation and rejection experienced by the unhoused. This thesis argues for the adoption of a neuroscience-informed model of recovery rooted in community reintegration and low-barrier housing with on-site support services.

Increasing evidence suggests that adults with disabilities have higher rates of drug misuse compared to adults without disabilities, however; there is limited information on rates of commonly misused prescription drugs (e.g., stimulants, opioids, tranquilizers) to quantify the magnitude of this disparity. Thus, the purpose of this cross-sectional study is to examine and compare prevalence rates of prescription drug misuse by disability status and age group in a national sample of U.S. adults.

Methods

Data (n=47,100 adults) from the 2021 National Survey on Drug Use and Health was stratified by age group: 1) 18-29 years; 2) 30-49 years; 3) 50 …

Effect Of Problematic Smartphone Usage On Reaction Time And Critical Flicker Fusion Frequency Among Medical Undergraduate Students In Chennai, South India - A Cross-Sectional Study, Saisubramanian Abeetha, Angappan Suba, Mourali Chitra, Chirag D Jain, Saisubramanian Sadhana

Health Professions Education

Purpose: Smartphones are vital for communication and learning, especially among medical students, but excessive use can cause physical, psychological, and cognitive issues. Problematic Smartphone Usage (PSU), marked by compulsive use, is linked to attention deficits and reduced cognitive function. Reaction Time (RT) reflects sensory-motor speed, while Critical Flicker Fusion Frequency (CFFF) indicates sensory processing and neural fatigue. Prolonged smartphone use may impair these parameters. Despite growing concern, data on PSU’s impact on RT and CFFF in medical students is limited. This study explores their association among undergraduates in Chennai.

Mitigating The Risk Of Qtc Prolongation When Using Haloperidol For Acute Treatment Of Cannabinoid Hyperemesis Syndrome In Adolescents And Young Adults, Sandra Merino, Lissette Tordera, Allison Jun, Sun Yang

Pharmacy Faculty Articles and Research

Background/Objectives: Cannabinoid Hyperemesis Syndrome (CHS), associated with long-term cannabinoid use, has been increasingly observed in emergency room visits as more states in the U.S. have legislatively permitted medical and recreational marijuana use. The acute management of CHS primarily focuses on antiemetic treatment and supportive care. However, both the condition itself and the antiemetic drugs, such as haloperidol, may cause QTc prolongation. Methods: We reported two adolescent cases admitted to the emergency department for acute antiemesis management of CHS who received haloperidol treatment. A literature review was performed through October 2024 for previously published cases of QTc prolongation and/or …

Factors Affecting Waiting Times To Enter Opioid Use Disorder Treatment In The United States With A Particular Focus On Potential Biological Sex Disparity, Stanley Nkemjika, Kenneth Oforeh, Connie Olwit, Olaniyi Olayinka, Terence Tumenta

Department of Psychiatry and Human Behavior Faculty Papers

AIM: Opioid use disorder (OUD) is the problematic use of licit or illicit opioids. Thus far, the literature on biological sex differences in accessing treatment is scarce. Hence, we hypothesize that biological sex has a moderating effect on OUD treatment accessibility. We aim to explore biological sex differences in treatment disparities and its role in wait time to enter OUD treatment.

METHOD: Using the 2018 Treatment Episode Data Set Discharge, the national sample representative of OUD patients in the substance use disorder treatment facilities within the 50 states of the United States was 382,547. Univariate and multivariable logistic analysis of …

Factors Associated With Cognitive Flexibility In People With Opioid-Use Disorder: A Pilot Study, Paul S. Regier, Thais Costa Macedo De Arruda, Laura Sinko, Anne M. Teitelman, Anna Rose Childress

College of Nursing Faculty Papers & Presentations

The ability to adapt to changing circumstances has strong survival value. Individuals with substance use disorders tend to get "stuck" over-responding to drug-reward signals and pursuing drugs despite negative consequences. A lack of flexibility may be tied to impairments in neurocognition, including learning, memory, and executive function. However, results are often mixed, potentially due to heterogeneity in factors such as mental health, personality traits, or prior adversity. This study aimed to identify which factors influence neurocognitive variations within the opioid use disorder (OUD) population. Based on prior literature, we hypothesized that individuals with OUD would show deficits (vs. controls) in …

Comprehensive Community Medicine, Alexander Walther

Capstone Projects and Master's Theses

Comprehensive Community Medicine (CCM) is a theoretical framework designed to address the complex needs of individuals with dual diagnoses of mental illness and substance use disorders (SUDs). Dual diagnosis is highly prevalent, particularly among populations experiencing homelessness, and is associated with poorer health outcomes and increased healthcare service utilization. Structural inequities, including a fractured healthcare system, exacerbate the challenges faced by this vulnerable group. Research indicates that effective care for dually diagnosed individuals requires a layered approach addressing clinical, systemic, legal, and housing barriers.

The development of CCM has been informed by interviews with local stakeholders, including County EMS board …
