The Development Of Tumour Vascular Networks, Cassandra B Iroz, Willemijn L A Schäfer, Julie K Johnson, Meagan S Ager, Reiping Huang, Salva N Balbale, Jonah J Stulberg

Faculty, Staff and Student Publications

BACKGROUND: Opioids prescribed to treat postsurgical pain have contributed to the ongoing opioid epidemic. While opioid prescribing practices have improved, most patients do not use all their pills and do not safely dispose of leftovers, which creates a risk for unsafe use and diversion. We aimed to generate consensus on the content of a "safe opioid use agreement" for the perioperative settings to improve patients' safe use, storage, and disposal of opioids.

METHODS: We conducted a modified three-round Delphi study with clinicians across surgical specialties, quality improvement (QI) experts, and patients. In Round 1, participants completed a survey rating the …

The Effect Of An Educational Handout On Knowledge, Awareness And Attitudes Of Pre-Exposure Prophylaxis (Prep) Among Participants At A Needle And Syringe Exchange Site, Mckenzie Buckel

DNP Projects

Background: In 2018, the total number of HIV cases in the United States was 1.2 million. Almost 186,500 of these cases were attributed to intravenous drug use. With the adherence to pre-exposure prophylaxis (PrEP) there is approximately a 49% decrease in the rates of HIV among people who inject drugs and the most significant barrier to PrEP among this population is a lack of awareness and knowledge.

Objective: The purpose of this study was to determine participants’ of a needle and syringe exchange site knowledge, awareness and attitudes of PrEP after reviewing an educational handout about PrEP.

Methods: A quasi …

Faculty, Staff and Students Publications

Background: Cigarette smoking remains the leading avoidable cause of premature death in the United States, accounting for approximately 500,000, or 1 in 5, deaths annually. We explored trends in cigarette smoking among US adolescents.

Methods: We used data for adolescents in grades 9 through 12 from 1991 to 2021 from the Youth Risk Behavior Survey provided by the US Centers for Disease Control and Prevention. We explored trends overall as well as by sex, race/ethnicity, and school grade.

Results: All cigarette use—assessed as ever, occasional, frequent, or daily—among adolescents declined markedly from 1991 to 2021. Specifically, ever use significantly decreased …

Comparing Cigarette-Cue Attentional Bias Between People With Hiv/Aids And People With Opioid Use Disorder Who Smoke, Gopalkumar Rakesh, Joseph L Alcorn, Rebika Khanal, Seth S Himelhoch, Craig R Rush

Faculty, Staff and Student Publications

BACKGROUND: Special populations like people living with HIV/AIDS (PLWHA) and people with opioid use disorder (OUD) smoke tobacco cigarettes at rates three to four times greater than the general population. Patients with tobacco use disorder exhibit attentional bias (AB) for cigarette cues. Eye tracking can quantify this bias by measuring fixation time (FT) on cigarette and matched neutral cues, to calculate an AB score. Although previous studies have measured this bias in people who smoke without any other comorbid conditions, no study, to our knowledge, has measured or compared this bias in special populations.

METHODS: We performed exploratory analyses on …

Within Subject Cross-Tissue Analyzes Of Epigenetic Clocks In Substance Use Disorder Postmortem Brain And Blood, Brenda Cabrera-Mendoza, Laura Stertz, Katherine Najera, Sudhakar Selvaraj, Antonio L Teixeira, Thomas D Meyer, Gabriel R Fries, Consuelo Walss-Bass

Faculty, Staff and Student Publications

There is a possible accelerated biological aging in patients with substance use disorders (SUD). The evaluation of epigenetic clocks, which are accurate estimators of biological aging based on DNA methylation changes, has been limited to blood tissue in patients with SUD. Consequently, the impact of biological aging in the brain of individuals with SUD remains unknown. In this study, we evaluated multiple epigenetic clocks (DNAmAge, DNAmAgeHannum, DNAmAgeSkinBlood, DNAmPhenoAge, DNAmGrimAge, and DNAmTL) in individuals with SUD (n = 42), including alcohol (n = 10), opioid (n = 19), and stimulant use disorder (n = 13), and controls (n = 10) in …

Sociodemographic Differences In Menthol Cigarette Use In The United States, Rajesh Talluri, Sanjay Shete

Faculty, Staff and Student Publications

Background: Menthol cigarette use is associated with higher smoking initiation and reduced smoking cessation. We investigated sociodemographic differences in menthol and nonmenthol cigarette use in the United States.

Methods: We used the most recent available data from the May 2019 wave of the nationally-representative Tobacco Use Supplement to the Current Population Survey. The survey weights were used to estimate the national prevalence of individuals who currently smoke among individuals who use menthol and nonmenthol cigarettes. Survey-weighted logistic regression methods were used to estimate the association of menthol cigarette use with formerly smoking cigarettes and attempting to quit within the past …

Determinism V. Free Will & Genetic Evidence Of Addiction In Plea Bargaining And Sentence Mitigation: Conversion Of Incarceration To Probation And Rehabilitation Based On Genetic Addiction Risk Severity (Gars) Test, Kenneth Blum, Paul Mullen, Richard Green

St. Mary's Law Journal

In this Article, Dr. Kenneth Blum and his team present the case of a presently abstinent, thirty-five year old alcoholic (“AG”) who has several convictions for DWI. AG has undergone and continues to be engaged in out-patient substance abuse treatment. He entered treatment before adjudication and was mandated by the court to continue treatment to assist in maintaining sobriety. Treatment included the administration of the Genetic Addiction Risk Severity (“GARS”) Test.

AG was facing a probable five-year sentence for his fifth DWI conviction in Bexar County, Texas. However, because AG’s genetic risk results indicated a genetically induced dopamine dysfunction, hypodopaminergia, …

Hdac6 Inhibition Reverses Cisplatin-Induced Mechanical Hypersensitivity Via Tonic Delta Opioid Receptor Signaling, Jixiang Zhang, Jazzmine M Junigan, Ronnie Trinh, Annemieke Kavelaars, Cobi J Heijnen, Peter M Grace

Faculty, Staff and Student Publications

Peripheral neuropathic pain induced by the chemotherapeutic cisplatin can persist for months to years after treatment. Histone deacetylase 6 (HDAC6) inhibitors have therapeutic potential for cisplatin-induced neuropathic pain since they persistently reverse mechanical hypersensitivity and spontaneous pain in rodent models. Here, we investigated the mechanisms underlying reversal of mechanical hypersensitivity in male and female mice by a 2 week treatment with an HDAC6 inhibitor, administered 3 d after the last dose of cisplatin. Mechanical hypersensitivity in animals of both sexes treated with the HDAC6 inhibitor was temporarily reinstated by a single injection of the neutral opioid receptor antagonist 6β-naltrexol or …

Cue-Induced Cocaine Craving Enhances Psychosocial Stress And Vice Versa In Chronic Cocaine Users, Ann-Kathrin Kexel, Bruno Kluwe-Schiavon, Markus R Baumgartner, Etna J E Engeli, Monika Visentini, Clemens Kirschbaum, Erich Seifritz, Beate Ditzen, Leila M Soravia, Boris B Quednow

Faculty, Staff and Student Publications

Stress and craving, it has been found, contribute to the development and maintenance of and relapse in cocaine use disorder. Chronic cocaine users (CU), previous research has shown, display altered physiological responses to psychosocial stress and increased vegetative responding to substance-related cues. However, how psychosocial stress and cue-induced craving interact in relation to the CU's physiological responses remains largely unknown. We thus investigated the interaction between acute psychosocial stress and cocaine-cue-related reactivity in 47 CU and 38 controls. In a crossed and balanced design, the participants were randomly exposed to a video-based cocaine-cue paradigm and the Trier Social Stress Test …

Cigarette smoking is associated with epigenetic changes that may be reversible following smoking cessation. Whole blood DNA methylation was evaluated in Framingham Heart Study Offspring (n = 169) and Third Generation (n = 30) cohort participants at two study visits 6 years apart and in Atherosclerosis Risk in Communities (ARIC) study (n = 222) participants at two study visits 20 years apart. Changes in DNA methylation (delta β values) at 483,565 cytosine-phosphate-guanine (CpG) sites and differentially methylated regions (DMRs) were compared between participants who were current, former, or never smokers at both visits (current-current, former-former, never-never, respectively), versus those who …

Influence Of Pregabalin Maintenance On Cannabis Effects And Related Behaviors In Daily Cannabis Users, Joshua A Lile, Joseph L Alcorn, Lon R Hays, Thomas H Kelly, William W Stoops, Michael J Wesley, Philip M Westgate

Faculty, Staff and Student Publications

No medications are approved for cannabis use disorder (CUD), though a small clinical trial demonstrated that the voltage-dependent calcium channel (VDCC) ligand gabapentin reduced cannabis use in treatment seekers. VDCCs are modulated by cannabinoid (CB) ligands, and there are shared effects between CB agonists and VDCC ligands. This overlapping neuropharmacology and the initial clinical results supported the evaluation of pregabalin, a "next-generation" VDCC ligand, as a CUD medication. Two separate placebo-controlled, double-blind, counterbalanced, within-subjects human laboratory studies tested placebo and 300 (N = 2 females, 11 males; Experiment [EXP] 1) or 450 (N = 3 females, 11 males; …

(2) Forty-eight heavy drinking AUD patients (34 males (M)/14 females (F)) participated in this study. Patients were grouped by serum alanine aminotransferase (ALT) level (a marker of liver injury) as group 1 (Group 1 (Gr.1); ALT ≤ 40 U/L, 7M/8F, without any indication of early-stage ALD) and group 2 (Group 2 (Gr.2); ALT > 40 U/L, 27M/6F or early-stage ALD). These patients …

Associations Between Cannabis, Psychosis, And Schizophrenia In Adolescents, Lauren Moment

Academic Leadership Journal in Student Research

The effects of cannabis use on the brain, mind, and body have been studied for decades. The developing brain, particularly the adolescent and young adult brain, undergoes critical development that makes it especially susceptible to the effects of cannabis use. Among the adverse effects of cannabis use in adolescence and young adulthood, psychosis and psychotic disorders (e.g., schizophrenia) have been examined. The association of cannabis use with schizophrenia was first elucidated in a Swedish study of army conscripts. Specifically, conscripts reported their cannabis use exposure and were followed longitudinally to assess the emergence of schizophrenia. The authors found that those …

Cellular Bioenergetics: Experimental Evidence For Alcohol-Induced Adaptations, Liz Simon, Patricia E. Molina

School of Medicine Faculty Publications

At-risk alcohol use is associated with multisystemic effects and end-organ injury, and significantly contributes to global health burden. Several alcohol-mediated mechanisms have been identified, with bioenergetic maladaptation gaining credence as an underlying pathophysiological mechanism contributing to cellular injury. This evidence-based review focuses on the current knowledge of alcohol-induced bioenergetic adaptations in metabolically active tissues: liver, cardiac and skeletal muscle, pancreas, and brain. Alcohol metabolism itself significantly interferes with bioenergetic pathways in tissues, particularly the liver. Alcohol decreases states of respiration in the electron transport chain, and activity and expression of respiratory complexes, with a net effect to decrease ATP content. …

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Objective
To determine if treatment with a 5-HT3 antagonist (ondansetron) reduces need for opioid therapy in infants at risk for neonatal opioid withdrawal syndrome (NOWS).

Study Design
A multicenter, randomized, placebo controlled, double blind clinical trial of ninety (90) infants. The intervention arms were intravenous ondansetron or placebo during labor followed by a daily dose of ondansetron or placebo in infants for five days.

Results
Twenty-two (49%) ondansetron-treated and 26 (63%) placebo-treated infants required pharmacologic treatment (p>0.05). The Finnegan score was lower in the ondansetron-treated group (4.6 vs. 5.6, p=0.02). A non-significant trend was noted for the duration of …

Association Of Alcohol Use And Physical Activity With Body Mass Index In Mexican-Origin Adults, Natalia I Heredia, Qiong Dong, Shine Chang, Lorna H Mcneill

Faculty, Staff and Student Publications

BACKGROUND: Studies across racial/ethnic groups indicate that physical activity (PA) and alcohol consumption are positively associated, and that alcohol consumption is negatively associated with body mass index (BMI), but this relationship is less often evaluated in Hispanics. The purpose of this study was to assess the relationships between alcohol consumption, PA, and BMI in Hispanic adults.

METHODS: In this secondary data analysis of a Mexican-American cohort, we collected self-reported PA, alcohol consumption, and demographics, and measured height and weight. Linear regression assessed the association between PA and alcohol consumption with BMI, controlling for covariates. Total sample for analyses was n …

Gut Commensals Modulate Siv/Shiv Pathogenesis And Therapeutics, Samuel Johnson

Theses & Dissertations

Despite significant advancements in combination antiretroviral therapy (cART), ongoing inflammation in the brain and gut remain two of the most significant hurdles in the health of people living with human immunodeficiency virus (HIV). Additionally, a viral reservoir in each compartment inhibits cure efforts by allowing rapid viral rebound following cART interruption. Emerging understanding of the gut-brain axis (GBA) implicates each compartment in the modulation of the other in a complex bi-directional interaction mediated by vagus innervation, circulating lymphocytes, and microbiome composition and biproducts. Using multiple models of the simian (and simian-human) immunodeficiency virus (SIV/SHIV) and therapeutic intervention, I present how …

Neuronal Activity Within The Ventral Tegmental Area Is Correlated With Cocaine-Seeking Behavior In Male, But Not Female, Rats, Colton D. Spencer, Nicole M. Hinds, Ireneusz D. Wojtas, Desta M. Pulley, Daniel Manvich

Rowan-Virtua Research Day

The objective of this study was to begin to determine the neurobiological underpinnings of psychosocial stress-induced cocaine seeking. Social defeat stress, achieved using the well-established resident-intruder procedure, is an ecologically-valid psychosocial stressor in rodents that may more closely recapitulate those psychosocial experiences that elicit cocaine craving and relapse in human cocaine users. Our laboratory has developed a model of psychosocial stress-induced relapse in rats in which extinguished cocaine seeking is reinstated by re-exposure to a discrete cue that signals impending social defeat stress. We previously reported that an individual rat’s predilection towards the display of active coping behaviors during prior …

Morphine-Induced Hyperactivity Is Attenuated By Intra-Accumbens Administration Of The Highly-Selective Dopamine D3 Receptor Antagonist Vk4-40, Mansi Patel, Desta M. Pulley, Daniel Manvich

Rowan-Virtua Research Day

Opioids exert their abuse-related effects by enhancing dopamine (DA) neurotransmission within the brain’s mesolimbic reward system, a neural projection involving DA neurons in the ventral tegmental area (VTA) that project to medium spiny neurons within the nucleus accumbens (NAc). Mu (MOR) are expressed by several populations of GABAergic neurons that tonically inhibit VTA DA neurons. By inhibiting these GABAergic neurons in a MOR-dependent manner, opioids indirectly enhance DA neurotransmission via disinhibition of DAergic neurons. Accumulating evidence indicates that selective pharmacological antagonism of the dopamine D3 receptor (D3R) attenuates the abuse-related effects of several opioids, but the neurobiological mechanisms mediating this …

Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz

Electronic Theses and Dissertations

Prenatal opioid exposure has been studied in relation to infants' medical outcomes. However, large gaps exist in the literature supporting early identification of atypical neurobehavior and motor development of infants with prenatal opioid exposure. The purpose of the study was to investigate whether prenatal opioid exposure has a negative influence on a newborn infant’s neurobehavior and motor development to aid in the early identification of potential delays. Using a prospective quasi experimental design, infants motor development using the Test of Infant Motor Performance (TIMP) and neurobehavior using the NICU Neonatal Network Scale (NNNS) was assessed on 58 infants in a …

Investigating The Role Of The Basolateral Amygdala Plays In The Incubation Of Cue-Induced Cocaine Seeking Behavior, Claire Marie Corbett

Graduate School of Biomedical Sciences Theses and Dissertations

Cocaine use disorder is a chronic, relapsing brain disease. Sex and ovarian hormones are known to influence cocaine addiction liability and relapse vulnerability. However, little is known regarding the cellular and synaptic mechanisms contributing to sex differences in relapse vulnerability, including how these measures are influenced by hormonal fluctuations. To investigate sex differences in relapse vulnerability we use a rodent model of cocaine craving and relapse called the incubation model in which cue-induced seeking progressively increases or “incubates” during the first month of withdrawal from extended-access cocaine self-administration. Using this model, we have recently shown that females in the estrus …

The Effects Of Rosiglitazone On Task Specific Anxiety-Like Behavior And Novelty Seeking In A Model Of Chronic Adolescent Unpredictable Stress, Hannah Sexton, Nathan A. Olszewski, Mary-Louise Risher

Biomedical Sciences

Adolescence is characterized as a period of increased social behavior, risk taking, and novelty seeking, partly due to ongoing maturation in critical brain areas and the hypothalamic-pituitary-adrenal (HPA) negative-feedback system. During this period there is heightened vulnerability to stress that can drive neuro-immune-endocrine remodeling, resulting in the emergence of maladaptive behaviors that increase susceptibility to alcohol and substance abuse. Here we used a rat model to investigate the impact of chronic adolescent unpredictable stress on a battery of behavioral measures to assess anxiety, novelty seeking, risk taking, depression, and voluntary ethanol consumption while determining whether the PPARγ agonist rosiglitazone can …

Mindfulness And Pain Regulation: The Role Of Acceptance And Commitment Therapy For Individuals With Chronic Pain, Ariana C. White

Honors Theses and Capstones

Chronic pain is a significant and widely prevalent health condition which requires comprehensive care to address the many facets contributing to symptomatology. In 2016, 20% of American adults (about 50 million) reported experiencing chronic pain, of which 7.4% indicated that chronic pain frequently limited their life and participation in activities within the past 3 months (CDC, 2018). As a result, many individuals with chronic pain turn to opioid-based medication for pain relief, but long-term use of opioids actually increases pain sensation (Tobin, 2019). Moreover, opioid medication is unable to target underlying mental health components which emerge as part of chronic …

Faculty, Staff and Student Publications

Cocaine use continues to be a significant public health problem with limited treatment options and no approved pharmacotherapies. Cognitive-behavioral therapy (CBT) remains the mainstay treatment for preventing relapse, however, people with chronic cocaine use display cognitive impairments that are associated with poor response to CBT. Emerging evidence in animal and human studies suggests that the peroxisome proliferator-activated receptor-gamma (PPAR- γ) agonist, pioglitazone, improves white matter integrity that is essential for cognitive function. This project will determine whether adjunctive use of pioglitazone enhances the effect of CBT in preventing relapse during the early phase of recovery from cocaine use disorder. This …

Evaluating The Efficacy Of Automated Smoking Treatment For People With Hiv: Protocol For A Randomized Controlled Trial, Damon J Vidrine, Thanh C Bui, Michael S Businelle, Ya-Chen Tina Shih, Steven K Sutton, Lokesh Shahani, Diana Stewart Hoover, Kristina Bowles, Jennifer I Vidrine

Faculty, Staff and Student Publications

BACKGROUND: Smoking prevalence rates among people with HIV are nearly 3 times higher than those in the general population. Nevertheless, few smoking cessation trials targeting smokers with HIV have been reported in the literature. Efforts to develop and evaluate sustainable, low-cost, and evidence-based cessation interventions for people with HIV are needed. Given the widespread proliferation of mobile phones, the potential of using mobile health apps to improve the reach and efficacy of cessation interventions is promising, but evidence of efficacy is lacking, particularly among people with HIV.

OBJECTIVE: This study will consist of a 2-group randomized controlled trial to evaluate …
