Substance use, childhood traumatic experience, and Posttraumatic Stress Disorder in an urban civilian population

Potential influence of socioeconomic status on genetic correlations between alcohol consumption measures and mental health

BACKGROUND

Frequency and quantity of alcohol consumption are metrics commonly used to measure alcohol consumption behaviors. Epidemiological studies indicate that these alcohol consumption measures are differentially associated with (mental) health outcomes and socioeconomic status (SES). The current study aims to elucidate to what extent genetic risk factors are shared between frequency and quantity of alcohol consumption, and how these alcohol consumption measures are genetically associated with four broad phenotypic categories: (i) SES; (ii) substance use disorders; (iii) other psychiatric disorders; and (iv) psychological/personality traits.

METHODS

Genome-Wide Association analyses were conducted to test genetic associations with alcohol consumption frequency (N = 438 308) and alcohol consumption quantity (N = 307 098 regular alcohol drinkers) within UK Biobank. For the other phenotypes, we used genome-wide association studies summary statistics. Genetic correlations (rg) between the alcohol measures and other phenotypes were estimated using LD score regression.

RESULTS

We found a substantial genetic correlation between the frequency and quantity of alcohol consumption (rg = 0.52). Nevertheless, both measures consistently showed opposite genetic correlations with SES traits, and many substance use, psychiatric, and psychological/personality traits. High alcohol consumption frequency was genetically associated with high SES and low risk of substance use disorders and other psychiatric disorders, whereas the opposite applies for high alcohol consumption quantity.

CONCLUSIONS

Although the frequency and quantity of alcohol consumption show substantial genetic overlap, they consistently show opposite patterns of genetic associations with SES-related phenotypes. Future studies should carefully consider the potential influence of SES on the shared genetic etiology between alcohol and adverse (mental) health outcomes.

Mechanisms of Shared Vulnerability to Post-traumatic Stress Disorder and Substance Use Disorders

Psychoactive substance use is a nearly universal human behavior, but a significant minority of people who use addictive substances will go on to develop an addictive disorder. Similarly, though ~90% of people experience traumatic events in their lifetime, only ~10% ever develop post-traumatic stress disorder (PTSD). Substance use disorders (SUD) and PTSD are highly comorbid, occurring in the same individual far more often than would be predicted by chance given the respective prevalence of each disorder. Some possible reasons that have been proposed for the relationship between PTSD and SUD are self-medication of anxiety with drugs or alcohol, increased exposure to traumatic events due to activities involved in acquiring illegal substances, or addictive substances altering the brain's stress response systems to make users more vulnerable to PTSD. Yet another possibility is that some people have an intrinsic vulnerability that predisposes them to both PTSD and SUD. In this review, we integrate clinical and animal data to explore these possible etiological links between SUD and PTSD, with an emphasis on interactions between dopaminergic, adrenocorticotropic, GABAergic, and glutamatergic neurobehavioral mechanisms that underlie different emotional learning styles.

The effectiveness of substance use interventions for homeless and vulnerably housed persons: A systematic review of systematic reviews on supervised consumption facilities, managed alcohol programs, and pharmacological agents for opioid use disorder

BACKGROUND

Substance use is disproportionately high among people who are homeless or vulnerably housed. We performed a systematic overview of reviews examining the effects of selected harm reduction and pharmacological interventions on the health and social well-being of people who use substances, with a focus on homeless populations.

METHODS AND FINDINGS

We searched MEDLINE, EMBASE, PsycINFO, Joanna Briggs Institute EBP, Cochrane Database of Systematic Reviews and DARE for systematic reviews from inception to August 2019. We conducted a grey literature search and hand searched reference lists. We selected reviews that synthesized evidence on supervised consumption facilities, managed alcohol programs and pharmacological interventions for opioid use disorders. We abstracted data specific to homeless or vulnerably housed populations. We assessed certainty of the evidence using the GRADE approach. Our search identified 483 citations and 30 systematic reviews met all inclusion criteria, capturing the results from 442 primary studies. This included three reviews on supervised consumption facilities, 24 on pharmacological interventions, and three on managed alcohol programs. Supervised consumption facilities decreased lethal overdoses and other high risk behaviours without any significant harm, and improved access to care. Pharmaceutical interventions reduced mortality, morbidity, and substance use, but the impact on retention in treatment, mental illness and access to care was variable. Managed alcohol programs reduced or stabilized alcohol consumption. Few studies on managed alcohol programs reported deaths.

CONCLUSIONS

Substance use is a common chronic condition impacting homeless populations. Supervised consumption facilities reduce overdose and improve access to care, while pharmacological interventions may play a role in reducing harms and addressing other morbidity. High quality evidence on managed alcohol programs is limited.

Traumatic Events and Substance Use Disorders in Adolescents

OBJECTIVES

Adolescents with substance use disorders (SUD) frequently report traumatic events (TEs) and symptoms of post-traumatic stress disorder (PTSD). This study aimed to assess whether lifetime prevalence rates of TEs and PTSD are related to SUD severity in adolescent psychiatric patients.

METHODS

We analyzed N = 114 self-reports of treatment-seeking German adolescents aged 12 to 18 years, who visited a specialized SUD outpatient unit. Standardized questionnaires were applied to assess SUD severity, the number of TEs and DSM-IV PTSD criteria.

RESULTS

Patients fulfilling PTSD criteria (28% of the total sample) had a higher Drug Use Disorders Identification Test (DUDIT) score compared to non-PTSD patients with TEs (p <.001), and compared to adolescents without TEs or PTSD (p = .003). Additionally, SUD severity was positively associated with the number of TEs and the number of intrusion, hyperarousal, and avoidance symptoms (all r = .33 to.48, all p <.01).

DISCUSSION

Adolescent patients with SUD reported 3-times higher rates of TEs, and a 5-time higher prevalence of PTSD following TEs, than the general adolescent population. Adolescent SUD patients with PTSD reported more severe substance use problems than patients without PTSD-regardless of previous TEs. Longitudinal studies are needed in order to investigate the temporal relationship between TEs, PTSD and SUD.

A genome-wide association study of cocaine use disorder accounting for phenotypic heterogeneity and gene–environment interaction

BACKGROUND

Phenotypic heterogeneity and complicated gene–environment interplay in etiology are among the primary factors that hinder the identification of genetic variants associated with cocaine use disorder.

METHODS

To detect novel genetic variants associated with cocaine use disorder, we derived disease traits with reduced phenotypic heterogeneity using cluster analysis of a study sample (n = 9965). We then used these traits in genome-wide association tests, performed separately for 2070 African Americans and 1570 European Americans, using a new mixed model that accounted for the moderating effects of 5 childhood environmental factors. We used an independent sample (918 African Americans, 1382 European Americans) for replication.

RESULTS

The cluster analysis yielded 5 cocaine use disorder subtypes, of which subtypes 4 (n = 3258) and 5 (n = 1916) comprised heavy cocaine users, had high heritability estimates (h2 = 0.66 and 0.64, respectively) and were used in association tests. Seven of the 13 identified genetic loci in the discovery phase were available in the replication sample. In African Americans, rs114492924 (discovery p = 1.23 × E−8), a single nucleotide polymorphism in LINC01411, was replicated in the replication sample (p = 3.63 × E−3). In a meta-analysis that combined the discovery and replication results, 3 loci in African Americans were significant genome-wide: rs10188036 in TRAK2 (p = 2.95 × E−8), del-1:15511771 in TMEM51 (p = 9.11 × E−10) and rs149843442 near LPHN2 (p = 3.50 × E−8).

LIMITATIONS

Lack of data prevented us from replicating 6 of the 13 identified loci.

CONCLUSION

Our results demonstrate the importance of considering phenotypic heterogeneity and gene–environment interplay in detecting genetic variations that contribute to cocaine use disorder, because new genetic loci have been identified using our novel analytic method.

Child Maltreatment, Fathers, and Adolescent Alcohol and Marijuana Use Trajectories

Background: Little is known about heterogeneity in developmental trajectories of alcohol and marijuana use among at-risk youth. Objective: This study aims to examine how child maltreatment and father structural factors at different stages in the life course are associated with different patterns of alcohol and marijuana use trajectories. Methods: A sample of youth (N = 903) were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Latent class growth analysis was employed to assess heterogeneity in patterns of adolescent alcohol and marijuana use. In addition, binary logistic regression analysis was performed to examine child maltreatment and father structural factors across different developmental stages as predictors of membership in the identified alcohol and marijuana use trajectory classes. Results: For both alcohol and marijuana use, two distinct latent classes were identified: stable no/low alcohol use (74%) vs. increasing alcohol use (26%); stable no/low marijuana use (85%) vs. increasing marijuana use (15%). Emotional abuse during early childhood and physical abuse during adolescence predicted membership in the increasing alcohol use and the increasing marijuana use classes. The presence of father in the home during early childhood was associated with lower likelihood of being in the increasing alcohol use class. Conclusions: Our findings highlight the importance of understanding the etiology of adolescent substance use through a developmental lens. Screening of exposure to child maltreatment across different developmental stages and interventions promoting father engagement during early childhood might help mitigate the risk of adolescent alcohol and marijuana use.

Childhood Maltreatment, Limbic Dysfunction, Resilience, and Psychiatric Symptoms

Previous research has indicated that childhood maltreatment is predictive of psychiatric symptoms in adulthood. Among the potential intervening factors in this relationship are affective reactions in the victims, neurodevelopmental problems, and resilience. The purpose of this study was to test, in a nonclinical low-risk sample, an integrative developmentally based psychoneurological model of the roles of limbic system dysfunction, shame and guilt, and resiliency as potential intervening variables between childhood maltreatment and adult psychiatric symptoms. Also of interest was whether there were gender-specific pathways from maltreatment to symptoms. Based on the results of preliminary analyses, several regressions were conducted separately by gender, entering the different forms of parental aggression at Step 1, resilience at Step 2, the resilience by parental aggression interaction term at Step 3, shame and guilt at Step 4, and limbic dysfunction at Step 5, as predictors of psychiatric symptoms. Analyses indicated that both maternal psychological maltreatment and paternal physical maltreatment were predictive of total psychiatric symptomatology in adulthood, with shame mediating the relationship in women and guilt mediating it in men, limbic system symptoms mediating the relationship in both genders, and trait resilience moderating the relationship in both genders.

The Role of Early Life Stress in HPA Axis and Anxiety

Substantial evidence from various studies suggests a preeminent role for early adverse experiences in the development of psychopathology. The most recent studies reviewed here suggest that early life stressors are associated with an increased risk for anxiety disorders in adulthood. Early life stress predisposes individuals to develop a number of psychiatric syndromes, particularly affective disorders, including anxiety disorders, and is therefore a significant health problem.This review examines the emerging literature on the relationship between stress, hypothalamic-pituitary-adrenal (HPA) axis function, and generalized anxiety disorder (GAD), panic disorder, and phobias and the role of early life stress as an important risk factor for HPA axis dysfunction.The most consistent findings in the literature show increased activity of the HPA axis in depression associated with hypercortisolemia and reduced inhibitory feedback. In addition to melancholic depression, a spectrum of other conditions may be associated with increased and prolonged activation of the HPA axis, including panic, GAD, phobias and anxiety. Moreover, HPA axis changes appear to be state-dependent, tending to improve upon resolution of the anxiety syndrome. Interestingly, persistent HPA hyperactivity has been associated with higher rates of relapse. These studies suggest that an evaluation of the HPA axis during treatment may help identify patients who are at a higher risk for relapse. These findings suggest that this dysfunction of the HPA axis is partially attributable to an imbalance between glucocorticoid and mineralocorticoid receptors. Evidence has consistently demonstrated that glucocorticoid receptor function is impaired in anxiety disorders. Moreover, normal basal cortisol levels and hyper-responsiveness of the adrenal cortex during a psychosocial stressor are observed in social phobics. Finally, abnormal HPA axis activity has also been observed in generalized anxiety disordered patients. Early stressful life events may provoke alterations of the stress response and thus of the HPA axis that can endure during adulthood, predisposing individuals to develop psychopathology.

Borderline personality disorder symptoms and exposure to violence as risk factors for opioid use in adulthood

Borderline personality disorder and exposure to violence are both risk factors for opioid use. While past research has identified these relationships, there has yet to be any study which investigates the potential that exposure to violence may help explain the relationship between borderline personality disorder symptoms and opioid use as a mediator. The present study used data from the Pathways to Desistance study to test these proposed relationships. Results indicated that greater levels of borderline personality disorder symptoms were associated with increased opioid use frequency. However, when exposure to violence variables were included in the model, the magnitude of this effect was attenuated by more than 20% and reduced to non-significance. These results indicate the importance of identifying and treating borderline personality disorder symptomatology and to provide increased oversight of the environments which juvenile offenders are exposed to upon reentry. Doing so may help to address the opioid crisis in the United States.

Posttraumatic Stress Disorder Symptom Association With Subsequent Risky and Problem Drinking Initiation

OBJECTIVES

Posttraumatic stress disorder (PTSD) and unhealthy alcohol use are commonly associated conditions. It is unknown whether specific symptoms of PTSD are associated with subsequent initiation of unhealthy alcohol use.

METHODS

Data from the first 3 enrollment panels (n = 151,567) of the longitudinal Millennium Cohort Study of military personnel were analyzed (2001-2012). Complementary log-log models were fit to estimate whether specific PTSD symptoms and symptom clusters were associated with subsequent initiation of 2 domains of unhealthy alcohol use: risky and problem drinking (experience of 1 or more alcohol-related consequences). Models were adjusted for other PTSD symptoms and demographic, service, and health-related characteristics.

RESULTS

Eligible study populations included those without risky (n = 31,026) and problem drinking (n = 67,087) at baseline. In adjusted analyses, only 1 PTSD symptom-irritability/anger-was associated with subsequent increased initiation of risky drinking (relative risk [RR] 1.05, 95% confidence interval [CI] 1.00-1.09) at least 3 years later. Two symptom clusters (dysphoric arousal [RR 1.17, 95% CI 1.11-1.23] and emotional numbing [RR 1.30, 95% CI 1.22-1.40]) and 5 symptoms (restricted affect [RR 1.13, 95% CI 1.08-1.19], sense of foreshortened future [RR 1.12, 95% CI 1.06-1.18], exaggerated startle response [RR 1.07, 95% CI 1.01-1.13], sleep disturbance [RR 1.11, 95% CI 1.07-1.15], and irritability/anger [RR 1.12, 95% CI 1.07-1.17]) were associated with subsequent initiation of problem drinking.

CONCLUSIONS

Findings suggest that specific PTSD symptoms and symptom clusters are associated with subsequent initiation of unhealthy alcohol use.

Sex-Dependent Changes in miRNA Expression in the Bed Nucleus of the Stria Terminalis Following Stress

Anxiety disorders disproportionately affect women compared to men, which may arise from sex differences in stress responses. MiRNAs are small non-coding RNAs known to regulate gene expression through actions on mRNAs. MiRNAs are regulated, in part, by factors such as stress and gonadal sex, and they have been implicated in the pathophysiology of multiple psychiatric disorders. Here, we assessed putative sex differences in miRNA expression in the bed nucleus of the stria terminalis (BNST) - a sexually dimorphic brain region implicated in anxiety - of adult male and female rats that had been exposed to social isolation (SI) stress throughout adolescence. To assess the translational utility of our results, we assessed if childhood trauma in humans resulted in changes in blood miRNA expression that are similar to those observed in rats. Male and female Sprague-Dawley rats underwent SI during adolescence or remained group housed (GH) and were tested for anxiety-like behavior in the elevated plus maze as adults. Small RNA sequencing was performed on tissue extracted from the BNST. Furthermore, we re-analyzed an already available small RNA sequencing data set from the Grady Trauma Project (GTP) from men and women to identify circulating miRNAs that are associated with childhood trauma exposure. Our results indicated that there were greater anxiogenic-like effects and changes in BNST miRNA expression in SI versus GH females compared to SI versus GH males. In addition, we found nine miRNAs that were regulated in both the BNST from SI compared to GH rats and in blood samples from humans exposed to childhood trauma. These studies emphasize the utility of rodent models in studying neurobiological mechanisms underlying psychiatric disorders and suggest that rodent models could be used to identify novel sex-specific pharmacotherapies for anxiety disorders.

PTSD Symptom Clusters and Craving Differs by Primary Drug of Choice

Objective: Research has demonstrated a cyclical relationship between posttraumatic stress disorder (PTSD) and substance use disorder. Identifying factors that link PTSD symptom clusters and substance use disorder may illuminate mechanisms underlying the PTSD-substance use disorder relationship, better informing interventions that target this comorbidity. The current study of individuals enrolled in an outpatient aftercare chemical dependency program in King County, Washington, assessed whether overall PTSD symptoms and specific PTSD symptom clusters predicted craving depending on individuals identified primary drug of choice (DOC). Methods: Participants eligible for the parent study were at least 18 years of age, fluent in English, medically cleared from substance withdrawal, and able to participate in treatment sessions and agreed to random assignment. Random assignment to either a mindfulness-based relapse prevention group, a standard relapse prevention group, or a treatment as usual group was conducted on a computer randomization program. A secondary analysis of baseline data was employed in the current study to determine which of the PTSD symptom clusters (avoidance, hyperarousal, and intrusion) predicted substance craving. Results: Covarying for severity of dependence, results suggest that overall PTSD scores predicted craving in participants who identified alcohol, stimulants, and opiates as their primary DOC. Further, avoidance-related PTSD symptoms alone predicted a significant proportion of the variability in craving in stimulant users, and hyperarousal symptoms alone predicted a significant proportion of the variability in craving in alcohol users. No specific PTSD cluster significantly predicted a proportion of the variability in craving in marijuana or opiates users. Conclusions: Findings suggest that craving may play a role in maintaining the relationship between specific PTSD symptom clusters and substance use disorder, and the nature of this relationship may differ by primary DOC. The clinical trial on which this secondary analysis of data was conducted is registered as NCT01159535 at www.clinicaltrials.gov.The original trial from which data for this study was drawn was supported by the National Institutes of Health [NIH/NIDA 5 R01 DA025764-02].

U.S. Opioid Epidemic: Impact on Public Health and Review of Prescription Drug Monitoring Programs (PDMPs)

OBJECTIVES

In recent years, the devastating effects of U.S. opioid epidemic has been making news headlines. This report explores background information and trends on opioid misuse, overdose fatalities and its impact on public health. In addition, various efforts to improve surveillance, timeliness of data and Prescription Drug Monitoring Program (PDMP) integration and interoperability are reviewed.

METHOD

PubMed and internet searches were performed to find information on the U.S. opioid epidemic. In addition, searches were performed to retrieve information about PDMPs and state-specific mandates along with presentation slides and learnings from the 2018 National Rx Drug Abuse & Heroin Summit in Atlanta, GA.

RESULTS

It is clear that the U.S. opioid epidemic has a tremendous impact on public health including the next generation of children. Various data, surveillance & technology-driven efforts including CDC-Funded Enhanced State Opioid Overdose Surveillance Program (ESOOS) and use of telemedicine for opioid use disorder treatment aim to improve prevention, treatment and targeted interventions. In addition, PDMP integration and interoperability efforts are advancing to provide prescribers meaningful decision support tools.

DISCUSSION

The opioid epidemic has a complex impact on public health intertwined with variable factors such as mental health and social determinants of health. Given the statistics and studies that suggest many of the illicit opioid users start with prescription opioids, continued advancement in the area of PDMP integration and interoperability is necessary. The PDMP integrated clinical decision support systems need to supply to healthcare providers access to complete, timely and evidence-based information that can meaningfully inform prescribing decisions and communication with patients that affect measurable outcomes.

CONCLUSION

While Prescription Drug Monitoring Programs (PDMPs) are valuable tools for providers in making informed prescribing decisions, the variable state mandates and varying degrees of integration and interoperability across states may limit their potential as meaningful decision support tools. Sharing best practices, challenges and lessons learned among states and organizations may inform strategic and systematic use of PDMPs to improve public health outcomes.

Personal and Socioeconomic Determinants in Medication-assisted Treatment of Opioid Use Disorder in Adolescents and Young Adults

Opioid use disorder (OUD) is a pediatric and adolescent problem as most young adults (aged <25 years) in treatment programs report initiating use before 25 years of age, and there are lifelong impacts from early substance use necessitating early screening for opioid use and subsequent treatment. Medication-assisted treatment (MAT) is a highly effective intervention for OUD, and there is strong evidence for its use with adolescents; however, most adolescents with OUD are unable to access MAT or remain in MAT long term to achieve substantial recovery. Using case examples drawn from a pediatric and adolescent physician's experiences proving MAT to adolescents and young adults (ages 16-24 years), this article explores the personal and socioeconomic determinants in MAT of OUD in adolescents and young adults and provides suggestions for advocacy areas and resources to improve MAT with this population.

Violence exposure, conflict, and health outcomes in inner-city African American adolescents

PURPOSE

To examine relationships among community and school violence exposure, parent-adolescent conflict, coping style, and self-reported health in a sample of 432 high-risk, inner-city African American adolescents at age 14 years.

DESIGN AND METHODS

Multiple regression and principal component analysis were used to analyze the secondary data. After controlling for multiple covariates (eg, sex, age, blood lead levels, and socioeconomic status), both violence exposure and posttraumatic stress symptoms (PTSS) were related to health outcomes. The survey of exposure to community violence, the safe-school survey, and the conflict tactics scale were used to measure community violence, school violence, and parent-adolescent conflict. Coping was evaluated using the general coping scale. The child health illness profile-adolescent edition was used to obtain self-reported health measures, and the clinician-assisted PTSD scale was used to measure PTSS.

RESULTS

Higher exposure to community violence was associated with less emotional comfort, less family involvement, higher individual risk, and poorer academic and work performance. Parent-adolescent conflict predicted less physical and emotional comfort and poorer home safety and health.

CONCLUSIONS

Our findings suggest that it is important to evaluate both violence exposure and the responses to the exposure, which can include both PTSS and diverse coping strategies.

Managing job performance, social support and work-life conflict to reduce workplace stress

Purpose

Workplace stress costs £3.7bn per annum in the UK and in excess of $300bn per annum in the USA. The purpose of this paper is to examine the existence, strength and direction of relationships between perceptions of social support, work–life conflict, job performance and workplace stress in an Irish higher education institution.

Design/methodology/approach

The selected theoretical framework consisted of a combination of reward imbalance theory, expectancy theory and equity theory. An organizational stress screening survey instrument was used to survey the staff (n= 1,420) of an academic institution. Multiple linear regression analysis was used to evaluate the relationships between the independent variables (social support, work–life conflict, job performance), the covariates (staff category, direct reports, age, gender), and the dependent variable (workplace stress).

Findings

The results showed a negative correlation between social support and workplace stress, a positive correlation between work–life conflict and workplace stress, and a negative correlation between job performance and workplace stress (p< 0.05). The results also revealed significant relationships between the covariates direct reports and gender and the dependent variable workplace stress.

Practical implications

The findings from this research can trigger an organizational approach where educational leaders can enable workplace change by developing and implementing social support and work–life strategies, and potential pathways to reduce levels of workplace stress and improve quality of life for employees and enhance performance.

Originality/value

The examination and establishment of particular relationships between social support, work–life conflict and job performance with workplace stress is significant for managers.

Animal Models of PTSD: The Socially Isolated Mouse and the Biomarker Role of Allopregnanolone

Post-traumatic stress disorder (PTSD) is a debilitating undertreated condition that affects 8%-13% of the general population and 20%-30% of military personnel. Currently, there are no specific medications that reduce PTSD symptoms or biomarkers that facilitate diagnosis, inform treatment selection or allow monitoring drug efficacy. PTSD animal models rely on stress-induced behavioral deficits that only partially reproduce PTSD neurobiology. PTSD heterogeneity, including comorbidity and symptoms overlap with other mental disorders, makes this attempt even more complicated. Allopregnanolone, a neurosteroid that positively, potently and allosterically modulates GABAA receptors and, by this mechanism, regulates emotional behaviors, is mainly synthesized in brain corticolimbic glutamatergic neurons. In PTSD patients, allopregnanolone down-regulation correlates with increased PTSD re-experiencing and comorbid depressive symptoms, CAPS-IV scores and Simms dysphoria cluster scores. In PTSD rodent models, including the socially isolated mouse, decrease in corticolimbic allopregnanolone biosynthesis is associated with enhanced contextual fear memory and impaired fear extinction. Allopregnanolone, its analogs or agents that stimulate its synthesis offer treatment approaches for facilitating fear extinction and, in general, for neuropsychopathologies characterized by a neurosteroid biosynthesis downregulation. The socially isolated mouse model reproduces several other deficits previously observed in PTSD patients, including altered GABAA receptor subunit subtypes and lack of benzodiazepines pharmacological efficacy. Transdiagnostic behavioral features, including expression of anxiety-like behavior, increased aggression, a behavioral component to reproduce behavioral traits of suicidal behavior in humans, as well as alcohol consumption are heightened in socially isolated rodents. Potentials for assessing novel biomarkers to predict, diagnose, and treat PTSD more efficiently are discussed in view of developing a precision medicine for improved PTSD pharmacological treatments.

Marijuana use motives mediate the association between experiences of childhood abuse and marijuana use outcomes among emerging adults

INTRODUCTION

Experiences of childhood sexual abuse (CSA) and childhood physical abuse (CPA) are associated with poor mental health outcomes including substance use in subsequent years. Marijuana use motives (i.e., coping with negative affect, enhancing positive affect, or improving social interactions) may influence problematic substance use among young adults. Specifically, motives may be associated with severity of marijuana use outcomes among individuals who have experienced CSA or CPA. This study investigated the indirect effect of marijuana use motives between experiences of CSA or CPA and marijuana use and problems among emerging adults.

METHOD

Participants were 397 young adults (50.1% male, 66.2% White) between ages 18-25 years, who reported 15.85 (SD = 11.66) days of marijuana use in the past month. Participants reported on history of childhood abuse, marijuana use days, problems, and motives for use.

RESULTS

Findings suggest a significant indirect effect of coping motives in the association between CPA and marijuana use days and marijuana problems. Further, both coping motives and marijuana use days indicated a significant indirect effect between CPA and problems. Motives of socializing or enhancement did not have a significant indirect effect between CPA and marijuana use or problems. There were no significant findings with CSA and marijuana use outcomes.

DISCUSSION

Coping motives might be an important potential target for future marijuana interventions in persons with childhood physical abuse.

Clinical Opinion Letters Regarding Breastfeeding and Neonatal Abstinence Syndrome for Child Apprehension Family Court Proceedings

The accelerating reach of opioid use disorder in North America includes increasing prevalence among pregnant people. In Canada, the rate of Neonatal Abstinence Syndrome (NAS) rose 27% between 2012-2013 and 2016-2017, and it is estimated that 0.51% of all infants now experience NAS after delivery. Pregnant people are a priority population for access to opioid replacement therapy programs. Participation in such programs demonstrates significant commitment to self-care among pregnant people and concern for fetal and infant wellbeing. Participation in opioid replacement therapy often results in family surveillance by Child Protection Services and infant apprehension. Children of Indigenous descent are held in foster care at high and disproportionate rates.The Convention on the Rights of the Child principle of Best Interests of the Child governs family law and child access decisions. The value of breastfeeding for all children and in particular for children recovering from NAS can be a consideration in the Best Interest of the Child. Clinicians with expertise in lactation may support the breastfeeding dyad to remain together by preparing Clinical Opinion Letters for the court. This Insights into Policy presents a how-to description of the content of clinical opinion letters in such cases, including context and process considerations, client background, breastfeeding science, and factors specific to neonatal abstinence syndrome.

Internalizing and externalizing factors on the pathway from adverse experiences in childhood to non-medical prescription opioid use in adulthood

BACKGROUND

Research demonstrates strong associations between adverse childhood experiences (ACEs) and non-medical prescription opioid use (NMPO), but pathways are not understood, hindering prevention and treatment responses.

METHODS

We assessed hypothesized mediators of the association between ACEs and NMPO in a nationally-representative U.S.

SAMPLE

National Longitudinal Study of Adolescent to Adult Health data (N = 12,288) yielded an ordinal exposure comprising nine ACEs (neglect; emotional, physical, sexual abuse; parental incarceration and binge drinking; witnessed, threatened with, experienced violence) and a binary lifetime NMPO outcome. Nine potential mediators measured in adolescence and/or adulthood included depression, anxiety, suicidality, delinquency, impulsivity, and risk-taking. We estimated adjusted odds ratios (AOR) and 95% confidence intervals (CI) for sex-stratified associations of: ACEs and mediators; mediators and NMPO; and ACEs and NMPO adjusting for mediators individually and simultaneously.

RESULTS

All associations of ACEs and mediators were statistically significant and similar by sex. All mediators had statistically significant associations with NMPO (except one depression measurement for each sex). Delinquency was strongly associated with ACEs and NMPO and was the strongest individual mediator. Every ACE increase was associated with increased NMPO odds of 32% for males and 27% for females. Adjusting for all mediators, odds of NMPO were attenuated partially for males [AOR = 1.18 (95% CI:1.07, 1.31)] and somewhat more for females [AOR = 1.11 (95% CI:1.00, 1.25)].

CONCLUSIONS

Internalizing and externalizing factors partially explained the pathway from ACEs to NMPO. Substance abuse may be more difficult to treat with co-occurring psychopathologies and maladaptive behaviors, highlighting the need to address trauma early in life.

What Trauma Looks Like for Incarcerated Men: A Study of Men's Lifetime Trauma Exposure in Two State Prisons

OBJECTIVE

While it is understood that high rates of trauma exposure are common among incarcerated male populations, there is limited data on the nature of the trauma exposure. This study sought to develop foundational knowledge about the trauma experiences of incarcerated men in order to provide a basis for further theory building in this area.

METHOD

This study used a quantitative-qualitative approach to examine the trauma histories of a randomly selected sample of 67 men incarcerated in the Missouri Department of Corrections.

RESULTS

The analyses revealed several patterns among study participants, including near universal trauma exposure in adolescence with the most frequent exposures involving witnessing or being proximate to violent deaths of family and friends. The mean age of exposure for all trauma exposure types measured was 17 years old. We found that for this group of incarcerated men, trauma exposures in childhood tended to result more from community violence than child maltreatment (e.g., abuse and neglect by caregivers).

CONCLUSION

The study results suggested that further research may be needed into the effects of close proximity to violent death during this particular window in adolescent development. Neuroscience research has shown that this is a "sensitive period" in brain development with potential negative outcomes in early adulthood, including emotional regulation deficits that can potentially lead to increased risk of arrest. Further research on trauma exposure within this population is needed both to appropriately serve men while in prison or in the process of reentering society and to support efforts to reduce mass incarceration.

Typologies of PTSD clusters and reckless/self-destructive behaviors: A latent profile analysis

Posttraumatic stress disorder (PTSD) is comorbid with diverse reckless and self-destructive behaviors (RSDBs). We examined the nature and construct validity (covariates of age, gender, depression severity, number of trauma types, functional impairment) of the optimal class solution categorizing participants based on PTSD symptom and RSDB endorsement. The sample included 417 trauma-exposed individuals recruited through Amazon's MTurk platform who completed the Life Events Checklist for DSM-5, PTSD Checklist for DSM-5, the Posttrauma Risky Behaviors Questionnaire, and Patient Health Questionnaire-9. Latent profile analyses indicated an optimal three-class solution: the Low PTSD-RSDBs, High PTSD-Low RSDBs, and High PTSD-RSDBs classes. Multinomial logistic regression indicated that impairment and depression predicted the High PTSD-Low RSDBs vs. the Low PTSD-RSDBs classes. Impairment, age, being female, and depression predicted the High vs. Low PTSD-RSDBs classes. Number of trauma types, age, being female, and depression predicted the High PTSD-RSDBs vs. High PTSD-Low RSDBs classes. Results support the presence of a reckless behaviors subtype of PTSD (characterized by greater depression, greater impariment, greater number of trauma types, being male, and being younger), conducting comprehensive assessments of RSDBs for individuals reporting PTSD symptoms and of PTSD symptoms for individuals reporting RSDBs, and the need to tailor interventions to treat PTSD and RSDBs concurrently.

Developmental Trajectories of Early Life Stress and Trauma: A Narrative Review on Neurobiological Aspects Beyond Stress System Dysregulation

Early life stressors display a high universal prevalence and constitute a major public health problem. Prolonged psychoneurobiological alterations as sequelae of early life stress (ELS) could represent a developmental risk factor and mediate risk for disease, leading to higher physical and mental morbidity rates in later life. ELS could exert a programming effect on sensitive neuronal brain networks related to the stress response during critical periods of development and thus lead to enduring hyper- or hypo-activation of the stress system and altered glucocorticoid signaling. In addition, alterations in emotional and autonomic reactivity, circadian rhythm disruption, functional and structural changes in the brain, as well as immune and metabolic dysregulation have been lately identified as important risk factors for a chronically impaired homeostatic balance after ELS. Furthermore, human genetic background and epigenetic modifications through stress-related gene expression could interact with these alterations and explain inter-individual variation in vulnerability or resilience to stress. This narrative review presents relevant evidence from mainly human research on the ten most acknowledged neurobiological allostatic pathways exerting enduring adverse effects of ELS even decades later (hypothalamic-pituitary-adrenal axis, autonomic nervous system, immune system and inflammation, oxidative stress, cardiovascular system, gut microbiome, sleep and circadian system, genetics, epigenetics, structural, and functional brain correlates). Although most findings back a causal relation between ELS and psychobiological maladjustment in later life, the precise developmental trajectories and their temporal coincidence has not been elucidated as yet. Future studies should prospectively investigate putative mediators and their temporal sequence, while considering the potentially delayed time-frame for their phenotypical expression. Better screening strategies for ELS are needed for a better individual prevention and treatment.

Cumulative childhood interpersonal trauma is associated with reduced cortical differentiation between threat and non-threat faces in posttraumatic stress disorder adults

OBJECTIVE

Posttraumatic stress disorder and childhood trauma frequently co-occur. Both are associated with abnormal neural responses to salient emotion stimuli. As childhood trauma is a risk factor for posttraumatic stress disorder, differentiating between their neurophysiological effects is necessary to elucidate the neural pathways by which childhood trauma exposure contributes to increased posttraumatic stress disorder risks.

METHODS

Face-specific N170 evoked response potentials for backward-masked (non-conscious) and conscious threat (fear, angry) and non-threat (happy) faces were measured in 77 adults (18-64 years old, 64% women, 78% right-handed) symptomatic for posttraumatic stress disorder. Differences in N170 peak amplitudes for fear-versus-happy and angry-versus-happy faces at bilateral temporo-occipital (T5, T6) sites were computed. The effect of cumulative exposure to childhood interpersonal trauma, other childhood trauma, adult trauma, depression and posttraumatic stress disorder symptom severity on the N170 response was assessed using hierarchical multiple regression analyses.

RESULTS

T5 N170 peak amplitudes for non-conscious fear-versus-happy faces were inversely related to cumulative childhood interpersonal trauma after accounting for socio-demographic, clinical symptom and other trauma factors. Posttraumatic stress disorder Avoidance was positively associated with N170 peak amplitudes for non-conscious fear-versus-happy faces, primarily due to reduced N170 responsivity to happy faces.

CONCLUSION

Childhood interpersonal trauma exposure is associated with reduced discrimination between fear and happy faces, while avoidance symptom severity is associated with dampened responsivity to automatically processed happy faces in posttraumatic stress disorder adults. Results are discussed in terms of the likely contributions of impaired threat discrimination and deficient reward processing during neural processing of salient emotion stimuli, to increased risks of posttraumatic stress disorder onset and chronicity in childhood interpersonal trauma-exposed adults.

The effects of Psychoeducation on the Traumatic Perception of the Birth Phenomenon in women with Substance-use Disorders

Objective: The present study evaluates the traumatic perception of the birth phenomenon in women with substance-use disorders (SUD) and to investigate the effects of psychoeducation on this perception. Material and Methods: The study was conducted between January and July 2017, and involved 60 women with SUD who were divided into two groups: intervention (n = 30) and control (n = 30). The study was carried out using the semi-experimental "pre-post test matched group model," and the Traumatic Perception of Birth Psychoeducation Program (TPBPP) was applied. Results: Traumatic birth perception was found to be decreased after TPBPP was applied in four modules to women with SUD. Conclusion: TPBPP is an effective psychoeducation model in the reduction of the traumatic perception of birth in women with SUD.

From Traumatic Childhood to Cocaine Abuse: The Critical Function of the Immune System

BACKGROUND

Experiencing traumatic childhood is a risk factor for developing substance use disorder, but the mechanisms that underlie this relationship have not been determined. Adverse childhood experiences affect the immune system, and the immune system mediates the effects of psychostimulants. However, whether this system is involved in the etiology of substance use disorder in individuals who have experienced early life stress is unknown.

METHODS

In this study, we performed a series of ex vivo and in vivo experiments in mice and humans to define the function of the immune system in the early life stress-induced susceptibility to the neurobehavioral effects of cocaine.

RESULTS

We provide evidence that exposure to social stress at an early age permanently sensitizes the peripheral (splenocytes) and brain (microglia) immune responses to cocaine in mice. In the brain, microglial activation in the ventral tegmental area of social-stress mice was associated with functional alterations in dopaminergic neurotransmission, as measured by whole-cell voltage clamp recordings in dopamine neurons. Notably, preventing immune activation during the social-stress exposure reverted the effects of dopamine in the ventral tegmental area and the cocaine-induced behavioral phenotype to control levels. In humans, cocaine modulated toll-like receptor 4-mediated innate immunity, an effect that was enhanced in those addicted to cocaine who had experienced a difficult childhood.

CONCLUSIONS

Collectively, our findings demonstrate that sensitization to cocaine in early life-stressed individuals involves brain and peripheral immune responses and that this mechanism is shared between mice and humans.

Early life stress and trauma: developmental neuroendocrine aspects of prolonged stress system dysregulation

Experience of early life stress (ELS) and trauma is highly prevalent in the general population and has a high public health impact, as it can trigger a health-related risk cascade and lead to impaired homeostatic balance and elevated cacostatic load even decades later. The prolonged neuropsychobiological impact of ELS can, thus, be conceptualized as a common developmental risk factor for disease associated with increased physical and mental morbidity in later life. ELS during critical periods of brain development with elevated neuroplasticity could exert a programming effect on particular neuronal networks related to the stress response and lead to enduring neuroendocrine alterations, i.e., hyper- or hypoactivation of the stress system, associated with adult hypothalamic-pituitary-adrenal axis and glucocorticoid signaling dysregulation. This paper reviews the pathophysiology of the human stress response and provides evidence from human research on the most acknowledged stress axis-related neuroendocrine pathways exerting the enduring adverse effects of ELS and mediating the cumulative long-term risk of disease vulnerability in adulthood.

Implications of Increased Trait Impulsivity on Psychopathology and Experienced Stress in the Victims of Early Trauma With Suicidality

There is a paucity of research characterizing suicide-related factors in victims of early trauma (ET). This cross-sectional study investigated an increase in trait impulsivity of ET victims with suicidal ideation or behavior and its role in severity of psychopathologies and experienced stress. Using data of 401 Korean suicidal ideators and attempters, trait impulsivity, severity of psychopathologies, and stress levels in addition to sociodemographic and clinical characteristics were compared between the ET group and the no ET group. Three first-order factors of trait impulsivity measured in Barratt Impulsive Scale-11 (cognitive instability, motor, and [lack of] perseverance) as well as depression, anxiety, overall stress level, and stress from social relationships were significantly elevated in the ET group. Owing to the long-lasting neurobiological influences of ET, it is recommended clinically that victims be carefully monitored for the development of mental distress, such as depression and anxiety, even in adulthood.

The relationship between the level of exposure to stress factors and cannabis in recent onset psychosis

BACKGROUND

There is a lack of studies investigating the dose-response effect of childhood trauma, recent events and cannabis use on recent psychosis. This study aims to determine the relationship between the level of exposure to stress factors and cannabis use with psychosis and to determine the combination effect among these factors in predicting a psychotic disorder.

METHODS

146 recent onset psychotic (ROP) patients and 61 healthy controls were included. Childhood trauma was evaluated using the childhood trauma questionnaire (CTQ) and recent events using the Holmes-Rahe social readjustment scale. The pattern of cannabis use was assessed by a detailed interview. A hierarchical multiple regression was run in order to determine both the cumulative and independent contribution of each factor in predicting a psychotic disorder.

RESULTS

The highest levels of exposure to childhood trauma and cannabis were associated with psychosis while neither low nor high recent event exposure was associated. The combined effect of risk factors yielded a significant association with psychosis (ײ = 86.76, p < .001) explaining the 49% of its variation. ROP were more likely to be exposed to one, two or three environmental factors than HC. Exposed to two or all factors were 7.5-fold and 26.7-fold more likely to have a diagnosis of psychosis, respectively.

CONCLUSIONS

Our study provides evidence for a cumulative and a dose-response effect of environmental factors on recent psychosis. Considering that cannabis use and stress are highly prevalent in the population with psychosis, investigations of their relationships are needed to implement targeted prevention and treatment strategies.

A novel rat model of comorbid PTSD and addiction reveals intersections between stress susceptibility and enhanced cocaine seeking with a role for mGlu5 receptors

PTSD is highly comorbid with cocaine use disorder (CUD), and cocaine users with PTSD + CUD are more resistant to treatment. Here we sought to develop a rat model of PTSD + CUD in order to identify the neurobiological changes underlying such comorbidity and screen potential medications for reducing cocaine seeking in the PTSD population. We utilized a predator scent stress model of PTSD, wherein rats received a single exposure to the fox pheromone 2,5-dihydro-2,4,5-trimethylthiazoline (TMT). One week after TMT exposure, stress-susceptible (susceptible), intermediate, and resilient phenotypes were detected and were consistent with behavioral, corticosterone, and gene expression profiles 3 weeks post TMT. We assessed phenotypic differences in cocaine self-administration, extinction, and cue-primed reinstatement. Susceptible rats exhibited deficits in extinction learning and increased cue-primed reinstatement that was not prevented by Ceftriaxone, an antibiotic that consistently attenuates the reinstatement of cocaine seeking. TMT-exposed resilient rats displayed increased mGlu5 gene expression in the amygdala and medial prefrontal cortex and did not display the enhanced cocaine seeking observed in susceptible rats. Combined treatment with the mGlu5 positive allosteric modulator 3-Cyano-N-(1,3-diphenyl-1 H-pyrazol-5-yl)benzamide (CDPPB), fear extinction, and ceftriaxone prevented the reinstatement of cocaine seeking in susceptible rats with fear extinction an important mediating condition. These results highlight the need for animal models of PTSD to consider stress-responsivity, as only a subset of trauma-exposed individuals develop PTSD and these individuals likely exhibit distinct neurobiological changes compared with trauma-exposed populations who are resilient to stress. This work further identifies glutamate homeostasis and mGlu5 as a target for treating relapse in comorbid PTSD-cocaine addiction.

Risk factors of new onset anxiety and anxiety exacerbation in the perinatal period: A systematic review and meta-analysis

BACKGROUND

Even though more than 20% of women meet diagnostic criteria for an anxiety disorder during the perinatal period, very little is known about the predictors of these problems. As a result, we systematically reviewed the literature on risk factors for new onset anxiety and maternal anxiety exacerbation in the perinatal period.

METHODS

PubMed, MEDLINE, PsycINFO, CINAHL, Ovid, ProQuest Portal, and Web of Science were searched for studies assessing risk factors for the development of new onset anxiety or anxiety worsening in women during pregnancy and the postpartum period.

RESULTS

11,759 citations were identified, with 11 studies meeting eligibility criteria. New onset anxiety was assessed in 7 studies, anxiety worsening in 3, and 1 assessed both. Lower educational attainment, living with extended family members, multiparity, a family history of psychiatric disorders, hyperemesis gravidarum, comorbid sleep disorders, and prenatal oxytocin exposure were risk factors for new onset perinatal anxiety, while presence of comorbid psychiatric disorders and prenatal oxytocin were risk factors for anxiety worsening.

LIMITATIONS

Studies not explicitly stating whether participants had pre-existing anxiety disorders were excluded. As a result, meta-analysis was not possible for several risk factors.

CONCLUSIONS

Risk factors for new onset anxiety and anxiety worsening during the perinatal period include psychological, social, and biological exposures. Given the lack of studies differentiating women with and without pre-existing anxiety disorders, additional research is required in order to determine whether these factors differ from the non-puerperal population, as well as from each other.

Predictors of transitions across stages of heroin use and dependence prior to treatment-seeking among people in treatment for opioid dependence

BACKGROUND AND AIMS

Little is known about transition pathways among heroin users prior to treatment. This study examined the demographic and clinical predictors of transition speed from heroin use, to dependence, to first treatment episode.

METHODS

1149 heroin-dependent participants recruited from opioid agonist treatment clinics in Sydney, Australia, underwent a structured interview. Age of onset (AOO) was collected for heroin use, dependence and treatment-seeking, childhood maltreatment, psychiatric history and other substance dependence. Discrete-time survival analyses modelled years from onset of use to dependence, and from dependence to treatment-seeking, including demographic and clinical covariates.

FINDINGS

Median AOO for first heroin use, dependence and treatment-seeking was 18 years (inter-quartile range, or IQR = 6), 21 years (IQR = 7), and 24 years (IQR = 10) respectively. In adjusted models, younger birth cohorts (vs. born <1960), greater childhood maltreatment and later AAO of first heroin use were associated with more rapid transitions from heroin use to dependence. Living independently, parental violence, and alcohol dependence were associated with slower transitions. Earlier treatment-seeking was associated with younger birth cohorts, having dependent children and later AOO of dependence. Delayed treatment-seeking was associated with <10 years school education, living independently, depression and alcohol dependence.

CONCLUSIONS

In this treatment sample, onset of heroin use occurred during late adolescence, suggesting the need for targeted interventions in mid-adolescence. Transitions to heroin dependence, then treatment-seeking, occurred during early adulthood. Rapid transitions from use to dependence were associated with younger birth cohorts, greater exposure to childhood maltreatment, and later onset of use.

Regular past year cannabis use in women veterans and associations with sexual trauma

INTRODUCTION

This study sought to describe the prevalence of regular past year cannabis use (i.e., at least monthly use) in women veterans, to characterize women veterans reporting this level of use, and to examine the independent contributions of sexual trauma across the lifespan on regular past year cannabis use.

METHODS

A national online survey on women veterans' health, with targeted oversampling of lesbian and bisexual women, collected data from US armed forces women veterans, 18 or older, living in the US (N = 636).

RESULTS

Eleven percent of women reported regular cannabis use (5% heterosexual women; 21% lesbian/bisexual women). In bivariate analysis, identifying as a sexual and/or racial ethnic minority, younger age, being unmarried, reporting lower income, receiving VA services, smoking tobacco, and screening positive for alcohol misuse were positively associated with regular cannabis use. Additionally, a greater percentage of cannabis users reported experiencing childhood and adult sexual trauma and screened positive for posttraumatic stress disorder (PTSD) when compared to peers who did not use any drugs. In a multivariate model, the number of life eras women endorsed experiencing sexual trauma was significantly associated with regular cannabis use even when adjusting for demographic variables and PTSD symptoms.

CONCLUSIONS

Among women veterans, regular cannabis use is fairly common among those who are sexual and racial/ethnic minorities, younger, unmarried, receiving VA services, and reporting alcohol or tobacco use, PTSD symptoms, and/or multiple sexual traumas across the lifespan. Screening and assessment may be important to consider in healthcare settings serving this veteran population.

Re-evaluation of the KMSK scales, rapid dimensional measures of self-exposure to specific drugs: Gender-specific features

BACKGROUND

The Kreek-McHugh-Schluger-Kellogg (KMSK) scales provide a rapid assessment of maximal self-exposure to specific drugs and can be used as a dimensional instrument. This study provides a re-evaluation of the KMSK scales for cannabis, alcohol, cocaine, and heroin in a relatively large multi-ethnic cohort, and also the first systematic comparison of gender-specific profiles of drug exposure with this scale.

METHODS

This was an observational study of n = 1,133 consecutively ascertained adult volunteers. The main instruments used were the SCID-I interview (DSM-IV criteria) and KMSK scales for cannabis, alcohol, cocaine, and heroin.

RESULTS

Participants were 852 volunteers (297 female) with specific DSM-IV abuse or dependence diagnoses, and 281 volunteers without any drug diagnoses (154 female). Receiver operating characteristic (ROC) curves were calculated for concurrent validity of KMSK scores with the respective DSM-IV dependence diagnoses. The areas under the ROC curves for men and women combined were 99.5% for heroin, 97% for cocaine, 93% for alcohol, and 85% for cannabis. Newly determined optimal KMSK "cutpoint" scores were identical for men and women for cocaine and heroin dependence diagnoses, but were higher in men than in women, for cannabis and alcohol dependence diagnoses.

CONCLUSIONS

This study confirms the scales' effectiveness in performing rapid dimensional analyses for cannabis, alcohol, cocaine, and heroin exposure, in a cohort larger than previously reported, with "cutpoints" changed from initial determinations, based on this larger sample. The KMSK scales also detected gender differences in self-exposure to alcohol and cannabis that are associated with the respective dependence diagnoses.

Importance of Behavioral Therapy in Patients Hospitalized for Post-Traumatic Stress Disorder (PTSD) with Opioid Use Disorder

Objective: To analyze differences in demographic pattern and hospitalization outcomes in post-traumatic stress disorder (PTSD) with opioid use disorder (OUD) patients managed with versus without behavioral therapy (BT). Methods: We conducted case-control study using Nationwide Inpatient Sample and identified PTSD and OUD using ICD–9–CM codes. Linear regression model was used to evaluate impact of BT on inpatient stay and cost. Results: We analyzed 1531 inpatient admissions and 786 patients received BT. Females had higher odds of receiving BT during inpatient management for PTSD with OUD (OR 1.210; 95% CI 1.020–1.436). About 63.1% patients receiving BT were benefited by Medicaid. Patients receiving BT had an increase in hospital stay by 1.27 days (P = 0.085) and hospitalization cost by $4734 (P = 0.018). There were no transfers to short term hospitals and lower transfers to skilled nursing facility (3.8% vs. 10.1%) in patients receiving BT. Conclusion: This study aims to reinforce combination management with psychotropic medications and BT in PTSD patients with comorbid OUD during hospitalization as it significantly decreases adverse disposition of the patient and thereby improves the quality of life post-treatment.

Differential relationships of PTSD and childhood trauma with the course of substance use disorders

A large body of research documents the link between Posttraumatic Stress Disorder (PTSD) and the course of Substance Use Disorders (SUD). Similar relationships have been reported between Childhood Trauma (CT) and the course of illness in patients with SUD even in the absence of PTSD, but few studies have examined differential effects of PTSD and CT (independent of PTSD) in this population. We used the International Diagnostic Checklist (IDCL) and the Posttraumatic Diagnostic Scale (PDS) to diagnose PTSD in a sample of patients with SUD (N = 459). The Childhood Trauma Questionnaire (CTQ) and the European Addiction Severity Index (EuropASI) were administered to assess childhood trauma and addiction related problems including comorbid psychopathological symptoms. The sample was divided into three groups: patients with experiences of CT and PTSD (CT-PTSD), experiences of CT without PTSD (CT-only), and neither experiences of CT nor PTSD (No trauma) to examine their differential associations with the course and severity of SUD. Patients of both the CT-PTSD (n = 95) and the CT-only group (n = 134) reported significantly higher levels of anxiety and depression as well as more suicidal thoughts and suicide attempts during their lifetime than the No trauma group (n = 209). Regarding most variables a graded association became apparent, with the highest level of symptoms in the CT-PTSD group, an intermediate level in the CT-only group and the lowest level in the No trauma group. The CT-PTSD group also differed in almost all substance use variables significantly from the No trauma group, including a younger age at first use of alcohol and cannabis, more cannabis use in the last month, and more lifetime drug overdoses. Our results confirm the relationships of both CT and PTSD with psychiatric symptoms in patients with SUD. Thus, it seems important to include both domains into the routine assessment of SUD patients. Specific treatments for comorbid PTSD but also for other consequences of childhood trauma should be integrated into SUD treatment programs.

Teenage Trauma Patients Are at Increased Risk for Readmission for Mental Diseases and Disorders

BACKGROUND

Most studies of readmission after trauma are limited to single institutions or single states. The purpose of this study was to determine the risk factors for readmission after trauma for mental illness including readmissions to different hospitals across the United States.

MATERIALS AND METHODS

The Nationwide Readmission Database for 2013 and 2014 was queried for all patients aged 13 to 64 y with a nonelective admission for trauma and a nonelective readmission within 30 d. Multivariable logistic regression was performed for readmission for mental diseases and disorders.

RESULTS

During the study period, 53,402 patients were readmitted within 30 d after trauma. The most common major diagnostic category on readmission was mental diseases and disorders (12.1%). The age group with the highest percentage of readmissions for mental diseases and disorders was 13 to 17 y (38%). On multivariable regression, the teenage group was also the most likely to be readmitted for mental diseases and disorders compared to 18-44 y (odds ratio [OR] 0.45, P < 0.01) and 45-64 y (OR 0.24, P < 0.01). Other high-risk comorbidities included HIV infection (OR 2.4, P < 0.01), psychosis (OR 2.2, P < 0.01), drug (OR 2.0, P < 0.01), and alcohol (OR 1.4, P < 0.01) abuse.

CONCLUSIONS

Teenage trauma patients are at increased risk for hospital readmission for mental illness. Efforts to reduce these admissions should be targeted toward individuals with high-risk comorbidities such as HIV infection, psychosis, and substance abuse.

Childhood Adversity and Hazardous Drinking: The Mediating Role of Attachment Insecurity

BACKGROUND

Harmful alcohol use is associated with disease and mortality. Identifying new determinants of harmful drinking may aid the 16.3 million adults who have alcohol use disorders. Childhood adversity is associated with alcohol use, but is not amenable to change. Attachment insecurity (anxiety and avoidance) may be associated with alcohol use and may be a target for modification or used to personalize interventions.

OBJECTIVES

This study aims to (a) identify the association between attachment insecurity and harmful drinking, (b) determine if attachment insecurity may mediate between childhood adversity and harmful drinking, and (c) test sex as a moderator between attachment insecurity and harmful drinking in the mediation relationship.

METHODS

Adult primary care patients (N = 348, 60% women) completed a cross-sectional survey study using validated measures in 2012. Statistical analyses were performed using Hayes's PROCESS macro in SPSS.

RESULTS

Childhood adversity was reported by 61% of the cohort and 18% endorsed harmful drinking. Attachment anxiety was associated with harmful drinking (p >.001), but attachment avoidance was not (p =.11). Attachment anxiety may mediate between childhood adversity and harmful drinking (95% CI:.03-.14). Sex did not moderate the relationships between attachment anxiety and harmful drinking in the mediation relationship (women: 95% CI:.031-.179; men: 95% CI:.003.-.182). Conclusions/Importance: Attachment anxiety may mediate between childhood adversity and harmful drinking in both men and women. Attachment anxiety may be a potential therapeutic target for people with a history of childhood adversity.

Childhood interpersonal violence and adult alcohol, cannabis, and tobacco use disorders: variation by race/ethnicity?

BACKGROUND

Exposure to child maltreatment has been shown to increase lifetime risk for substance use disorders (SUD). However, this has not been systematically examined among race/ethnic groups, for whom rates of exposure to assaultive violence and SUD differ. This study examined variation by race/ethnicity and gender in associations of alcohol (AUD), cannabis (CUD), and tobacco (TUD) use disorders with three types of childhood interpersonal violence (cIPV): physical abuse, sexual abuse, and witnessing parental violence.

METHOD

Data from the National Epidemiologic Survey of Alcohol-Related Conditions-III (N: 36 309), a US nationally representative sample, was utilized to examine associations of DSM-5 AUD, CUD and TUD with cIPV among men and women of five racial/ethnic groups. Models were adjusted for additional risk factors (e.g. parental substance use problems, participant's co-occurring SUD).

RESULTS

Independent contributions of childhood physical and sexual abuse to AUD, CUD, and TUD, and of witnessing parental violence to AUD and TUD were observed. Associations of cIPV and SUD were relatively similar across race/ethnicity and gender [Odds Ratios (ORs) ranged from 1.1 to 1.9], although associations of physical abuse with AUD and TUD were greater among males, associations of parental violence and AUD were greater among females, and associations of parental violence with AUD were greater among Hispanic women and American Indian men.

CONCLUSIONS

Given the paucity of research in this area, and the potential identification of modifiable risk factors to reduce the impact of childhood interpersonal violence on SUDs, further research and consideration of tailoring prevention and intervention efforts to different populations are warranted.

Childhood trauma, combat trauma, and substance use in National Guard and reserve soldiers

BACKGROUND

The goal of this work was to examine associations among childhood trauma, combat trauma, and substance use (alcohol problems, frequent heavy drinking [FHD], current cigarette smoking, and current/lifetime drug use) and the interaction effects of childhood trauma and combat exposure on those associations among National Guard/reserve soldiers.

METHODS

Participants (N = 248) completed an electronic survey asking questions about their military experiences, physical and mental health, and substance use. Childhood trauma and combat exposure were examined jointly in regression models, controlling for age, marital satisfaction, and number of deployments.

RESULTS

Childhood trauma was associated with current drug use (trend level, odds ratio [OR] = 1.44, 95% confidence interval [CI]: 0.97, 2.14; P = .072) in the main effect model; however, there was not a significant interaction with combat. Combat exposure had a significant interaction with childhood trauma on alcohol problems (b = -0.56, 95% CI: -1.12, -0.01; P = .048), FHD (b = -0.27, 95% CI: -0.47, -0.08; P = .007), and lifetime drug use (OR = 1.78, 95% CI: 1.04, 3.04; P = .035). There were no associations with either of the trauma measures and current cigarette smoking.

CONCLUSIONS

These results demonstrate that childhood and combat trauma have differential effects on alcohol use, such that combat trauma may not add to the effect on alcohol use in those with greater child maltreatment but may contribute to greater alcohol use among those with low child maltreatment. As expected, childhood and combat trauma had synergistic effects on lifetime drug use. Screening for multiple types of trauma prior to enlistment and/or deployment may help to identify at-risk individuals and allow time for early intervention to prevent future adverse outcomes.

Psychological abuse, substance abuse distress, dissatisfaction with friendships, and incident psychiatric problems

OBJECTIVE

The aim of this study was to assess the mediating role of dissatisfaction with friendships in adulthood in the associations between psychological abuse in childhood, substance abuse distress in childhood, and incident psychiatric problems (IPPs) in adulthood over 13 years of follow-up.

METHODS

We used data collected from 1994 to 2008 within the framework of the Tromsø Study (N = 9502), a representative, longitudinal, prospective cohort study. Poisson regression analysis was used to assess the associations between psychological abuse, substance abuse distress, dissatisfaction with friendships in adulthood, and IPPs in adulthood. Indirect effects and proportion mediated (%) were assessed with the difference-in-coefficients method.

RESULTS

Psychological abuse (relative risk [RR] = 1.66, 95% confidence interval [CI]: 1.45-1.89) and substance abuse distress in childhood (RR = 1.38, 95% CI: 1.18-1.62) were associated with an increased risk of dissatisfaction with friendships in adulthood. Dissatisfaction with friendships in adulthood was associated with an increased risk of IPPs in adulthood (RR = 1.71, 95% CI: 1.33-2.20). Moreover, dissatisfaction with friendships in adulthood mediated 9.31% (95% CI: 4.25-14.57) of the association between psychological abuse in childhood and IPPs in adulthood, and 9.17% (95% CI: 4.35-16.33) of the association between substance abuse distress in childhood and IPPs in adulthood.

CONCLUSIONS

Dissatisfaction with friendships in adulthood mediates a minor proportion of the associations between psychological abuse, substance abuse distress, and IPPs in adulthood. Interventions aimed at decreasing dissatisfaction with friendships may dampen some of the effect of psychological abuse and substance abuse distress in childhood on IPPs in adulthood.

Lack of access to medical care during Hurricane Sandy and mental health symptoms

Destruction caused by natural disasters compromises medical providers' and hospitals' abilities to administer care. Hurricane Sandy was particularly devastating, resulting in massive disruptions of medical care in the region. This study aimed to determine whether a lack of access to medical care during Hurricane Sandy was associated with posttraumatic stress disorder (PTSD) symptoms and other mental health/substance abuse outcomes. A secondary aim was to examine whether having a chronic illness moderates those associations. Self-reported medical access and mental health symptomatology were obtained from New York City and Long Island residents (n = 1669) following Hurricane Sandy under the Leaders in Gathering Hope Together project (10/23/2013–2/25/2015) and Project Restoration (6/5/2014–8/9/2016). Multivariable logistic regressions were utilized to determine the relationship between lack of access to medical care and mental health outcomes. Of the 1669 participants, 994 (59.57%) were female, 866 (51.89%) were white, and the mean age was 46.22 (SD = 19.2) years old. Those without access to medical care had significantly higher odds of showing symptoms of PTSD (AOR = 2.71, CI = [1.77–4.16]), as well as depression (AOR = 1.94, CI = [1.29–2.92]) and anxiety (AOR = 1.61, CI = [1.08–2.39]) compared to those with access. Lack of access to care was associated with a 2.12 point increase in perceived stress scale score (SE = 0.63). The interaction between having a chronic illness and lack of access to medical care was not significantly associated with any outcomes. The findings emphasize the importance of making medical care more accessible to patients, both chronically and acutely ill, during natural disasters to benefit their physical as well as their mental health.

•

Individuals without access to medical care had asignificantly higher odds of showing symptoms of mental health difficulties.

•

Chronic illness did not moderate the relationship between a lack of access to care and mental health outcomes.

•

Access to medical care during natural disasters may benefit the mental health of survivors with and without chronic illness.</span>

Adverse Experiences in Childhood and Sexually Transmitted Infection Risk From Adolescence Into Adulthood

BACKGROUND

Childhood maltreatment, particularly sexual abuse, has been found to be associated with sexual risk behaviors later in life. We aimed to evaluate associations between a broad range of childhood traumas and sexual risk behaviors from adolescence into adulthood.

METHODS

Using data from Waves I, III and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we used logistic regression to estimate the unadjusted odds ratio (OR) and adjusted OR (AOR) for associations between 9 childhood traumas and a cumulative trauma score and three sexual risk outcomes (multiple partnerships, sex trade involvement, and sexually transmitted infection [STI]) in adolescence, young adulthood, and adulthood. We also examined modification of these associations by gender.

RESULTS

Associations between cumulative trauma score and sexual risk outcomes existed at all waves, though were strongest during adolescence. Dose-response-like relationships were observed during at least 1 wave of the study for each outcome. Violence exposures were strong independent correlates of adolescent sexual risk outcomes. Parental binge drinking was the only trauma associated with biologically confirmed infection in young adulthood (AOR, 1.46; 95% confidence interval [CI], 1.01-2.11), whereas parental incarceration was the trauma most strongly associated with self-reported STI in adulthood (AOR, 1.70; 95% CI, 1.11-2.58). A strong connection was also found between sexual abuse and sex trade in the young adulthood period (AOR, 2.17; 95% CI, 1.43-2.49).

CONCLUSIONS

A broad range of traumas are independent correlates of sex risk behavior and STI, with increasing trauma level linked to increasing odds of sexual risk outcomes. The results underscore the need to consider trauma history in STI screening and prevention strategies.
