Adverse Childhood Experiences, Coping and Resilience in Persons with Alcohol Use Disorder and Their Non-drinking Siblings in High-density Families: A Case-control Study

Background

Adverse childhood experiences (ACEs) increase the odds of alcohol use disorder (AUD).

Aim

To study the ACEs, coping, and resilience in persons with AUD and their non-drinking siblings from high-density families.

Methods

The study used a case-control study design. Using purposive sampling, 135 participants were selected; the sample consists of persons with AUD (n = 45), non-drinking siblings (n = 45), and healthy controls (n = 45), selected from out-patient and in-patient services from a government-run de-addiction centre in Bengaluru. Individuals were administered an ACEs questionnaire, Brief-COPE, and Connor-Davison Resilience scale. Descriptive statistics, Friedman's test, and Bonferroni's post-hoc test, Binary Logistic Regression were used for analysis.

Results

ACEs, coping, and resilience significantly differ across the three groups. Persons with AUD and their non-drinking siblings are comparable in terms of ACEs and having dysfunctional family members. Non-drinking siblings and healthy controls have similar coping and resilience. None of the healthy controls had dysfunctional family members.

Conclusion

ACEs are more prevalent and more frequent in persons with AUD. Individuals with AUD showed higher avoidant coping and lower resilience than their non-drinking siblings and healthy controls. Early identification of ACEs and interventions to build resilience and coping strategies could prevent individuals from developing AUD in high-density families.

Comorbidity of Lifetime History of Abuse and Trauma With Opioid Use Disorder: Implications for Nursing Assessment and Care

BACKGROUND

Opioid use disorder (OUD) is a public health crisis and is challenging to treat. Previous research has shown correlations between OUD, abuse/trauma, and chronic pain.

AIMS

The purpose of this study was to investigate history of lifetime sexual, physical, and/or emotional abuse among participants in a medication-assisted treatment (MAT) program for OUD, and to investigate associations between abuse history and chronic pain.

METHODS

This is a secondary analysis of intake data from a 2-year, nonexperimental cohort treatment program of patients with OUD in rural Colorado. De-identified data were provided by 476 adult MAT patients using the Adult Addiction Severity Index (ASI-6). The ASI-6 includes three yes/no questions about history of abuse (emotional, physical, and sexual), with separate scoring for "past 30 days" and "lifetime" abuse.

RESULTS

Lifetime history among MAT program for OUD patients was 23% for sexual abuse, 43% for physical abuse, and 58% for emotional abuse. History of physical abuse was significantly associated with having a chronic pain diagnosis, χ2 = 4.49, p = .03, and also with higher reported pain levels, t(460) = 2.71, p = .007.

CONCLUSION

Lifetime history of physical abuse was associated with OUD and chronic pain, yet standard pain assessments do not assess these factors. In health care settings, the implementation of standardized trauma-informed screening tools, prompt recognition of abuse/trauma history, and adjunct psychological interventions may reduce stigma, reduce opioid use escalation, and help patients overcome OUD.

Differences in the prevalence and clinical correlates of depressive symptoms in male patients with methamphetamine and heroin use disorder in a Chinese Han population

BACKGROUND AND OBJECTIVES

Comorbidity of substance use disorders and depression is a common phenomenon. It is well known that opioid addiction is neurobiologically distinct from psychostimulant addiction. However, direct comparisons of comorbid depressive symptoms in patients with methamphetamine (METH) use disorder (MAUD) and heroin use disorders (HUD) have been lacking until now.

METHODS

A total of 353 patients with methamphetamine use disorder, 76 patients with HUD, and 203 healthy controls were recruited. The Beck Depression Inventory (BDI-SF), the Desires for Drug Questionnaire (DDQ) and the short form of the Childhood Trauma Questionnaire (CTQ-SF) were used to measure participants' depressive symptoms, drug craving, and childhood abuse or neglect, respectively.

RESULTS

The prevalence of depressive symptoms was 35.41% (125/353) in MAUD and 56.57% (43/76) in MAUD, significantly higher than the 22.66% (46/203) in healthy controls. Furthermore, there was a significant difference in the total BDI score between the MAUD and HUD groups (F = 5.02, df = 1, 372, p = .026). Among MAUD, years of education, history of incarceration, month of abstinence and negative reinforcement scores were associated with depressive symptoms (all p < .05). Among HUD, duration of drug use, childhood emotional abuse and sexual abuse were associated with depressive symptoms (all p < .05).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

The prevalence and correlates of depressive symptoms differ between MAUD and HUD, adding to the existing literature. Therefore, treatment and intervention programs should be designed to address these unique correlates in HUD and MAUD patients.

Adverse childhood experiences, risk of opioid misuse and its pathway among students at a public university

OBJECTIVE

 We examine role of ACEs and pathways to risk of opioid misuse among young adults. Participants and Methods: A cross-sectional survey of validated measures of ACEs, risk of opioid misuse, and health conditions with a sample of 1,402 students from a large public university followed by multivariate logistic regression and pathway analysis. Results: Majority (61%) of participants reported at least one ACE. A dose-response relationship between numbers of ACEs with risk for opioid misuse was present. Compared to participants with no ACEs, participants with ≥4 ACEs and 0-3 ACEs were 2.93 (95% CI: 1.95, 4.39; p < 0.001) and 1.96 (95% CI: 1.46, 2.65; p < 0.001) times more likely to be at risk for opioid misuse, respectively. Having at least one existing or past health condition significantly mediated the association. Conclusions: Our findings suggest need to include assessment of ACEs as a screening criterion for opioid prescription and administration among college-aged individuals.

The impact of exposure to physical and sexual violence on opioid consequences among trauma-exposed individuals recruited from the community who use opioids

Interpersonal violence and opioid use disorder are significant and intersecting public health concerns in the USA. The current study evaluated the consequences associated with opioid use (e.g., physical, social, interpersonal, intrapersonal, and impulse control) as a function of a history of exposure to interpersonal trauma, specifically physical and sexual violence. Participants were 84 trauma-exposed individuals recruited from the community who use opioids (M age = 43.5 50% men; 55% white). Whereas no significant differences emerged in the consequences of opioid use based on a history of physical violence, individuals with a history of sexual violence demonstrated higher levels of impulsive consequences of opioid use compared to individuals without a history of sexual violence. These data highlight the importance of considering the role of exposure to sexual violence in the context of opioid use disorder treatment.

Resilience and traumatic childhood experiences of patients with opioid use disorder

We aim to explore childhood traumatic experiences and resilience of patients with OUD and compare these variables to healthy controls. Ninety-five patients and 83 healthy controls completed the Sociodemographic Data Form, Connor Davidson Psychological Resilience Scale (CDRS), and Childhood Trauma Questionnaire-33 (CTQ-33). We found that CTQ correlated negatively with CDRS in patients. T-test results showed significant differences between both groups regarding total and subscales' scores of CTQ-except overprotection-over control. Physical neglect predicted a decrease in resilience in patients with OUD. In conclusion, childhood traumas and resilience could be essential factors during patients' follow-up and treatment process with OUD.

The Impact of Physical and Sexual Violence on Opioid Consequences among Trauma- exposed Individuals Recruited from the Community who Use Opioids

Interpersonal violence and opioid use disorder are significant and intersecting public health concerns in the United States. The current study evaluated the consequences associated with opioid use as a function of history of interpersonal trauma, specifically physical and sexual violence. Participants were 84 trauma-exposed individuals recruited from the community who use opioids (M age = 43.5 50% men; 55% white). Whereas no significant differences emerged in the consequences of opioid use based on a history of physical violence, individuals with a history of sexual violence demonstrated higher levels of impulsive consequences of opioid use compared to individuals without a history of sexual violence. These data highlight the importance of considering the role of sexual violence in the context of opioid use disorder treatment.

Differential prevalence of Adverse Childhood Experiences (ACEs) by gender and substance used in individuals with cannabis, cocaine, opioid, and tobacco use disorders

Background: Adverse childhood experiences (ACEs) show a graded association with the development of substance use disorders (SUDs) and engagement in risky substance use behaviors. Women are overrepresented among individuals with more severe childhood adversity (≥4 types of ACEs) and may be at particular risk for aberrant substance use.Objectives: To assess the prevalence of ACEs among men and women with cannabis, opioid, cocaine, and tobacco use disorders.Methods: Non-treatment-seeking individuals participating in clinical addiction research at a single site completed the ACE questionnaire and provided a detailed substance use history. Data were analyzed using proportional odds models and logistic regression.Results: Most participants (424/565; 75%) reported at least one ACE, and more than one-quarter (156/565; 27%) reported severe childhood adversity. Relative to men (n = 283), women (n = 282) reported more ACEs (OR = 1.49; p = .01) and more experiences of emotional/physical abuse (OR = 1.52; p = .02), sexual abuse (OR = 4.08; p = .04), and neglect (OR = 2.30; p < .01). Participants in the cocaine (OR = 1.87; n = .01) and opioid (OR = 2.21; p = .01) use disorder, but not cannabis use disorder (OR = 1.46; p = .08), studies reported more severe adversity relative to the tobacco group. Relative to tobacco users, emotional/physical abuse (OR = 1.92; p = .02) and neglect (OR = 2.46; p = .01) scores were higher in cocaine users and household dysfunction scores were higher in opioid users (OR = 2.67; p = .01).Conclusion: The prevalence of ACEs differs with respect to both participant gender and primary substance used. Novel SUD treatment strategies that incorporate ACEs may be uniquely beneficial in specific subpopulations of people with SUDs.

We need to talk: The urgent conversation on chronic pain, mental health, prescribing patterns and the opioid crisis

The opioid crisis’ pathways from first exposure onwards to eventual illnesses and fatalities are multiple, intertwined and difficult to dissect. Here, we offer a multidisciplinary appraisal of the relationships among mental health, chronic pain, prescribing patterns worldwide and the opioid crisis. Because the opioid crisis’ toll is especially harsh on young people, emphasis is given on data regarding the younger strata of the population. Because analgesic opioid prescription constitute a recognised entry point towards misuse, opioid use disorder, and ultimately overdose, prescribing patterns across different countries are examined as a modifiable hazard factor along these pathways of risk. Psychiatrists are called to play a more compelling role in this urgent conversation, as they are uniquely placed to provide synthesis and lead action among the different fields of knowledge and care that lie at the crossroads of the opioid crisis. Psychiatrists are also ideally positioned to gauge and disseminate the foundations for diagnosis and clinical management of mental conditions associated with chronic pain, including the identification of hazardous and protective factors. It is our hope to spark more interdisciplinary exchanges and encourage psychiatrists worldwide to become leaders in an urgent conversation with interlocutors from the clinical and basic sciences, policy makers and stakeholders including clients and their families.

Social Suffering: Indigenous Peoples' Experiences of Accessing Mental Health and Substance Use Services

In this paper, we present findings from a qualitative study that explored Indigenous people's experiences of mental health and addictions care in the context of an inner-city area in Western Canada. Using an ethnographic design, a total of 39 clients accessing 5 community-based mental health care agencies were interviewed, including 18 in-depth individual interviews and 4 focus groups. Health care providers also were interviewed (n = 24). Data analysis identified four intersecting themes: normalization of social suffering; re-creation of trauma; the challenge of reconciling constrained lives with harm reduction; and mitigating suffering through relational practice. The results highlight the complexities of experiences of accessing systems of care for Indigenous people marginalized by poverty and other forms of social inequity, and the potential harms that arise from inattention to the intersecting social context(s) of peoples' lives. Service delivery that aims to address the mental health concerns of Indigenous people must be designed with awareness of, and responsiveness to, the impact of structural violence and social suffering on peoples' lived realities. A relational policy and policy lens is key to alleviate patterns of social suffering and counter the harms that are unwittingly created when social suffering is normalized.

An Illustrative Review of Substance Use-Specific Insights From the National Longitudinal Study of Adolescent to Adult Health

PURPOSE

The purpose of this illustrative, thematic review was to demonstrate the utility of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) for substance use research and to describe substance use-specific insights gained from Add Health research over the past 2 decades.

METHODS

We searched multiple electronic databases (PubMed, PsycInfo, and Web of Science) and selected an illustrative sample of 40 articles that used Add Health data and longitudinally examined a measure of alcohol, marijuana, or illicit drug use or prescription drug misuse as the exposure or outcome in association with diverse domains of additional factors assessed (social, emotional, behavioral, contextual, biological, and genetic).

RESULTS

Included articles identified several key associations between substance use behaviors and additional factors from a wide range of domains. For example, results from several studies indicated that experiences of sexual violence, adolescent dating violence, and intimate partner violence are associated with an increased likelihood of later prescription opioid misuse, heavy drinking, and marijuana use, with some differences by biological gender and race/ethnicity. Results from other studies showed that bidirectional associations between substance use and mental health differ by specific type of substance and mental health condition.

DISCUSSION

Existing research using Add Health data has provided valuable insights regarding substance use by leveraging the study's longitudinal design, the prospective nature of data collection, the breadth and depth of substance use questions assessed from adolescence to adulthood, the size and diversity of the cohort, and the wide range of additional factors measured over time.

“I'm putting a Band-Aid on a bullet hole the only way I know how:” a qualitative study of barriers and facilitators to opioid misuse and recovery in Nevada

Nevada, like the rest of the United States, is undergoing substantial challenges with opioid misuse and overdose deaths, further exacerbated by the COVID-19 pandemic. While much of the attention around opioid overdose prevention is centered on treatment and recovery, it is important to understand the factors that influence initiation of use, and the function opioids play in people’s everyday lives. We conducted qualitative semi-structured individual interviews using purposive and snowball sampling among 35 people across Nevada with a current or prior history of illegal opioid or nonmedical opioid use. Our study aimed to understand why people start to use drugs, why they continue to use, what motivates them to continue to use or to seek treatment, and why individuals maintain recovery or return to use. We found five significant themes as perceived by the participants: that trauma is a risk factor for drug misuse; that the function of opioids in everyday life is a source of temporary relief but highly disruptive in the longer term; that recovery is most often a complicated and nonlinear process; that there are many barriers to accessing services that are both logistical and psychosocial; and that compassion, hope, and having a sense of purpose are crucial to the recovery process. The experiences of the study participants portray opioid use as a rational choice to escape the emotional ramifications of trauma. However, due to the physiological dependence and physical risk of opioids, drug policies that criminalize addiction, societal stigma, and the barriers to timely access of harm reduction, treatment, and recovery services, opioid users often become trapped in a distressing and dangerous cycle. Lastly, respondents indicated that hope, value, belonging, and purpose are powerful factors in cultivating intrinsic motivation for making positive changes and fostering resilience in the recovery process. Opioid misuse services should help meet basic needs and incorporate holistic approaches to recovery that acknowledge past trauma and the complexity of the recovery process.

Adverse Childhood Experiences, Mental Health, and Risk Behaviors in Adulthood: Exploring Sex, Racial, and Ethnic Group Differences in a Nationally Representative Sample

This study examined sex, racial, and ethnic differences in the short- and long-term associations between adverse childhood experiences (ACEs), mental health, and risk behaviors in a nationally representative sample. Analysis was based on the National Longitudinal Study of Adolescent to Adult Health, a longitudinal cohort of U.S. adolescents followed in five waves of data collection from adolescence to adulthood. Analysis included design-based regression models to examine the associations between ACEs and proximal and distal outcomes (i.e., depression, suicidal ideation, number of sexual partners, binge drinking, current smoker) assessed in the transition to adulthood (mean age 21; 2001-2002) and adulthood (mean age 38; 2016-2018). Sex, racial, and ethnic interactions were included in regression models to examine effect modification in the association of ACEs, mental health, and risk behaviors. In this analytical sample (N = 9,690), we identified a graded association between ACEs and depression, suicide ideation, and current smoker status at both time points (i.e., mean age 21 and 38). Sex moderated the relationship between ACEs and depression at mean age 21, while race (i.e., American Indian versus White) moderated the relationship between ACEs and number of sexual partners at mean age 38. A greater number of cumulative traumatic experiences in childhood may amplify adverse health outcomes among women and adults of American Indian descent in particular.

Impact of adverse childhood experiences on the symptom severity of different mental disorders: a cross-diagnostic study

Background

Adverse childhood experiences have a significant impact on different mental disorders.

Objective

To compare differences in adverse childhood experiences among those with different mental disorders and their relationships in a cross-disorder manner.

Methods

The study included 1513 individuals aged ≥18 years : 339 patients with substance use disorders, 125 patients with schizophrenia, 342 patients with depression, 136 patients with bipolar disorder, 431 patients with obsessive-compulsive disorder (OCD), and 140 healthy controls. The Early Trauma Inventory Self Report-Short Form was used to investigate childhood traumatic experiences, and the Addiction Severity Index, Positive and Negative Syndrome Scale, Hamilton Depression Scale, Young Mania Rating Scale, and Yale-Brown Obsessive-Compulsive Scale were used to assess mental disorder severity. Correlation and multivariate logistic regression were analysed between adverse childhood experiences and clinical features.

Results

Levels of adverse childhood experiences were significantly different among different mental disorders. Moreover, 25.8% of patients with substance use disorders reported childhood trauma, which was significantly higher than found in the other four psychiatric disorder groups. Emotional abuse scores were positively correlated with disease severity: the higher the total trauma score, the more severe the mental disorder.

Conclusions

Adverse childhood experiences are a common phenomenon in those with mental disorders, and the level of trauma affects mental disorder severity. Emotional abuse is closely related to many mental disorders. The incidence or severity of mental disorders can be reduced in the future by reducing the incidence of adverse childhood experiences or by timely intervention in childhood trauma.

The effect of social network strain on suicidal ideation among middle-aged adults with adverse childhood experiences in the US: A twelve-year nationwide study

Objective

Building on literature that measured the association between social network strain (SNS) and suicidal ideation using conventional regression analyses, we examined the effect of SNS, due to adverse childhood experiences (ACEs), on suicidal ideation using instrumental variables (IV) to eliminate the potential biases that may have occurred in earlier studies due to residual confounding.

Methods

This retrospective cohort study linked longitudinal data from the National Survey of Midlife Development in the United States (MIDUS) Refresher Biomarker Project (2012–2016), the MIDUS Refresher Project (2011–2014), the MIDUS 2 Biomarker Project (2004–2009), and the MIDUS 2 Project (2004–2006). Participants completed a phone interview, self-administered survey, and biomarker data collection. Exposure indicators included self-reported suicidal ideation, ACEs, and SNS from family, spouse, and friends. IV analysis was used to evaluate the continuous local average treatment effect of SNS on suicidal ideation when SNS only varied due to variation in ACEs.

Results

Our sample included 1703 middle-aged adults (52.9% females), which were followed up for 12 years. An IV probit model controlling for sociodemographic characteristics found a one-standard-deviation reduction in SNS reduced suicidal ideation by 22.6% (p < 0.01). A comprehensively controlled IV probit model found that a one-standard-deviation reduction in SNS is associated with a 21.4% (p = 0.05) decrease in suicidal ideation.

Conclusions

The causal pathway from SNS (due to ACEs) to suicidal ideation among middle-aged adults was established using IV analysis in this large-scale longitudinal study. The magnitude of this effect is sufficient to warrant the development of programs to improve social network relationships among family, friends, and spouses/partners. Suicide prevention programs addressing SNS may significantly reduce suicidal ideation among middle-aged Americans who have experienced ACEs.

•

Social Network Strain (SNS) from family, spouse, and friends is common.

•

SNS derives from demands, criticisms, disappointments, and irritations.

•

SNS varies strongly with Adverse Childhood Experiences (ACEs).

•

Reductions in SNS due to fewer ACEs decrease suicidal ideation.

•

A one standard-deviation reduction in SNS lowers suicidal ideation by 20%.

Acting with awareness moderates the association between lifetime exposure to interpersonal traumatic events and craving via trauma symptoms: a moderated indirect effects model

BACKGROUND

History of exposure to traumatic events (ETE) is common among women in substance use disorder (SUD) treatment and is related to craving. We examined whether ETE (i.e., emotional, physical, sexual abuse) in childhood, adulthood, or both is related to craving via trauma symptoms and how trait mindfulness might attenuate this association.

METHODS

Baseline data from a larger randomized clinical trial of a mindfulness-based intervention for women (N = 245) in SUD treatment were used. Inclusion criteria were: 18-65 years of age, SUD diagnosis, English fluency, no cognitive impairment, and willingness to be audio recorded and provide consent. Demographics and validated measures of ETE, posttraumatic stress symptoms, trait mindfulness, and substance use craving were collected via in-person interviews. Descriptive statistics, correlational analysis, and relative direct, indirect, and conditional indirect effects models were run.

RESULTS

Most participants identified as Hispanic (58.5%), had at least a high school education (52.2%), with a mean age of 32.2. Women reported ETE in childhood only (20.4%), adulthood only (17.5%), both childhood and adulthood (50.0%), and never (11.4%). Compared to women with ETE in both childhood and adulthood, those with exposure in adulthood only (β = -.10, 95% CI = -.20, -.02) or no exposure (β = -.11, 95% CI = -.23, -.03; [∆R2= .347, F(8, 245) = 15.7, p < .001) had lower craving via lower trauma symptomatology but no difference when compared to those with ETE only in childhood. Acting with awareness moderated this indirect effect (∆R2 = .04, F(3, 245) = 4.66, p = .004. At low levels of awareness, women with ETE during both childhood and adulthood reported higher craving via trauma symptomatology than women with no exposure or only adulthood exposure.

CONCLUSIONS

Low levels of acting with awareness may worsen trauma symptoms after ETE, which in turn may lead to more craving for women in substance use treatment. Despite a small moderating effect size, acting with awareness may have clinical significance due to the prevalence of trauma symptoms among women in SUD treatment.

A retrospective cohort study describing characteristics of those repeatedly detained under Section 136 of the Mental Health Act over a 5-year period and the association with past abuse

Individuals repeatedly detained under Section 136 (S136) of the Mental Health Act account for a significant proportion of all detentions. This study provides a detailed analysis of those repeatedly detained ('repeat attenders') to a London Mental Health Trust, identifying key demographic profiles when compared to non-repeat attenders, describing core clinical characteristics and determining to what degree a past history of abuse might be associated with these.All detentions to the S136 suite at South West London and St George's Mental Health NHS Trust over a 5-year period (2015-2020) were examined. Data were collected retrospectively from electronic records. A total of 1767 patients had been detained, with 81 patients identified as being a 'repeat attenders' (having had > = 3 detentions to the S136 suite during the study period). Repeat attenders accounted for 400 detentions, 17.7% of all detentions.Repeat attenders included a higher proportion of females (49.4%, p = 0.0001), compared to non-repeat attenders, and a higher proportion of them were of white ethnicity (85.2%, p = 0.001). 52 (64%) patients reported being a victim of past abuse or trauma. Of repeat attenders who reported past abuse or trauma, a high proportion had diagnoses of personality disorders, with deliberate self-harm as the most common reason for detention. They were more commonly discharged home with community support, rather than considered for hospital admission. In light of these findings, this paper discusses support potential strategies for those most vulnerable to repeated S136 detention, thereby minimising the ever-growing number of S136 detentions in the UK.

Psychiatric Disorders and HIV Drug Risk Behaviors Among Individuals Under Community Correctional Supervision

The prevalence of human immunodeficiency virus (HIV) is nearly three times higher in the incarcerated population than in the general population in the United States, and over half of the incarcerated population has a psychiatric diagnosis. Individuals under community corrections supervision continue to receive limited attention regarding HIV prevention and surveillance. Anxiety-related, depressive-related, and post-traumatic stress disorders are high in the community corrections population and may be potential correlates of HIV risk behaviors. Examining the link between psychiatric diagnosis and HIV risk behavior within the community correctional setting may shed light on who is at greatest risk for HIV. Individuals within community corrections who participated in a clinical trial completed questionnaires and semistructured interviews to screen for psychiatric disorders and HIV risk behaviors. Multivariate analyses revealed that individuals of younger age, of White race, and with anxiety disorders engaged in greater HIV drug risk behaviors, providing preliminary implications for whom testing and prevention efforts should be emphasized.

Neural Underpinnings of Social Stress in Substance Use Disorders

BACKGROUND

Drug addiction is a complex brain disorder that is characterized by craving, withdrawal, and relapse, which can be perpetuated by social stress. Stemming from an acute life event, chronic stress, or trauma in a social context, social stress has a major role in the initiation and trajectory of substance use. Preclinical literature shows that early life stress exposure and social isolation facilitate and enhance drug self-administration. Epidemiological evidence links childhood adversity to increased risk for drug use and demonstrates that cumulative stress experiences are predictive of substance use severity in a dose-dependent manner. Stress and drug use induce overlapping brain alterations leading to downregulation or deficits in brain reward circuitry, thereby resulting in greater sensitization to the rewarding properties of drugs. Though stress in the context of addiction has been studied at the neural level, a gap in our understanding of the neural underpinnings of social stress in humans remains.

METHODS

We conducted a systematic review of in vivo structural and functional neuroimaging studies to evaluate the neural processes associated with social stress in individuals with substance use disorder. Results were considered in relation to participants' history of social stress and with regard to the effects of social stress induced during the neuroimaging paradigm.

RESULTS

An exhaustive search yielded 21 studies that matched inclusion criteria. Social stress induces broad structural and functional neural effects in individuals with substance use disorder throughout their lifespan and across drug classes. A few patterns emerged across studies: (1) many of the brain regions altered in individuals who were exposed to chronic social stress and during acute stress induction have been implicated in addiction networks (including the prefrontal cortex, insula, hippocampus, and amygdala); (2) individuals with childhood maltreatment and substance use history had decreased gray matter or activation in regions of executive functioning (including the medial prefrontal cortex, orbitofrontal cortex, anterior cingulate cortex), the hippocampal complex, and the supplementary motor area; and (3) during stress-induction paradigms, activation in the anterior cingulate cortex, caudate, and amygdala was most commonly observed.

CONCLUSIONS/IMPLICATIONS

A distinct overlap is shown between social stress-related circuitry and addiction circuitry, particularly in brain regions implicated in drug-seeking, craving, and relapse. Given the few studies that have thoroughly investigated social stress, the evidence accumulated to date needs to be replicated and extended, particularly using research designs and methods that disentangle the effects of substance use from social stress. Future clinical studies can leverage this information to evaluate the impact of exposure to trauma or adverse life events within substance use research. Expanding knowledge in this emerging field could help clarify neural mechanisms underlying addiction risk and progression to guide causal-experimental inquiry and novel prevention and treatment strategies.

Experiencias adversas en la infancia y el uso de drogas en la adolescencia y adultez: un análisis de la evidencia

El objetivo de este estudio es la revisión de la evidencia actual sobre la relación entre la vivencia de experiencias adversas en la infancia y el posterior uso de drogas en la adolescencia y adultez, y sus características. La metodología utilizada fue una revisión sistemática de publicaciones científicas, entre el periodo 2013-2017, disponibles en la base de datos Scopus sobre experiencias adversas en la infancia y el uso de drogas en la adolescencia y adultez que arrojó un total de 69 publicaciones incluidas en el estudio. Las experiencias adversas en la infancia presentan una elevada relación con el uso y/o abuso de drogas en la adolescencia y adultez. El consumo de drogas en adolescentes y adultos expuestos a experiencias traumáticas en la infancia se da principalmente en hombres. Las drogas mayormente usadas son alcohol, tabaco, cannabis y fármacos no recetados y, en menor medida, opioides, cocaína y anfetaminas. Las drogas, en este sentido, cumplen el rol de barrera química para distanciar el dolor emocional que deriva del recuerdo de las experiencias traumáticas y su intensa carga psíquica. Se requieren acciones de promoción del buen trato en la infancia, así como el abordaje terapéutico temprano de niños expuestos a experiencias traumáticas.

Associations between insufficient sleep and prescription opioid misuse among high school students in the United States

STUDY OBJECTIVES

The aim of this study was to estimate the association between insufficient sleep and prescription opioid misuse among US high school students.

METHODS

Participants were 6,884 high school students who self-reported on sleep duration and prescription opioid misuse in the 2019 Youth Risk Behavior Survey. Sleep duration was categorized by the Youth Risk Behavior Survey according to the American Academy of Sleep Medicine guidelines as follows: recommended sleep duration (8-9 hours) vs insufficient sleep (< 8 hours). Participants also reported whether they had any prescription opioid misuse during their lifetime and whether they had prescription opioid misuse within the past 30 days.

RESULTS

Most (79.4%) participants reported sleeping less than 8 hours per night. Among all youth, 12.9% reported lifetime prescription opioid misuse and 6.2% reported current prescription opioid misuse. Prevalence of both lifetime and current opioid medication misuse was higher among those also reporting insufficient sleep compared to those reporting recommended sleep duration (14.3% vs 7.7%, P < .0001 for lifetime misuse and 6.6% vs 4.3%, P = .0091 for current misuse). In multivariate models, insufficient sleep was associated with an increased odds of lifetime prescription opioid misuse (adjusted odds ratios = 1.4; 95% confidence interval, 1.1-1.2; P = .006); however, we did not find an association between sleep duration and current prescription opioid misuse in multivariate analysis.

CONCLUSIONS

Sleep duration is associated with lifetime opioid misuse among US youth. Longitudinal studies are needed to test whether causal relationships exist, and to understand biobehavioral mechanisms that underlie associations between sleep deficiency and opioid misuse in adolescents.

Opioid Use Disorder and Perinatal Outcomes

OBJECTIVES

Evidence on the perinatal health of mother-infant dyads affected by opioids is limited. Elevated risks of opioid-related harms for people with opioid use disorder (OUD) increase the urgency to identify protective factors for mothers and infants. Our objectives were to determine perinatal outcomes after an OUD diagnosis and associations between opioid agonist treatment and birth outcomes.

METHODS

We conducted a population-based retrospective study among all women with diagnosed OUD before delivery and within the puerperium period in British Columbia, Canada, between 2000 and 2019 from provincial health administrative data. Controlling for demographic and clinical characteristics, we determined associations of opioid agonist treatment on birth weight, gestational age, infant disorders related to gestational age and birth weight, and neonatal abstinence syndrome via logistic regression.

RESULTS

The population included 4574 women and 6720 live births. Incidence of perinatal OUD increased from 166 in 2000 to 513 in 2019. Compared with discontinuing opioid agonist treatment during pregnancy, continuous opioid agonist treatment reduced odds of preterm birth (adjusted odds ratio: 0.6; 95% confidence interval: 0.4-0.8) and low birth weight (adjusted odds ratio: 0.4; 95% confidence interval: 0.2-0.7). Treatment with buprenorphine-naloxone (compared with methadone) reduced odds of each outcome including neonatal abstinence syndrome (adjusted odds ratio: 0.6; 95% confidence interval: 0.4-0.9).

CONCLUSIONS

Perinatal OUD in British Columbia tripled in incidence over a 20-year period. Sustained opioid agonist treatment during pregnancy reduced the risk of adverse birth outcomes, highlighting the need for expanded services, including opioid agonist treatment to support mothers and infants.

Early life adversity promotes resilience to opioid addiction-related phenotypes in male rats and sex-specific transcriptional changes

Experiencing some early life adversity can have an "inoculating" effect that promotes resilience in adulthood. However, the mechanisms underlying stress inoculation are unknown, and animal models are lacking. Here we used the limited bedding and nesting (LBN) model of adversity to evaluate stress inoculation of addiction-related phenotypes. In LBN, pups from postnatal days 2 to 9 and their dams were exposed to a low-resource environment. In adulthood, they were tested for addiction-like phenotypes and compared to rats raised in standard housing conditions. High levels of impulsivity are associated with substance abuse, but in males, LBN reduced impulsive choice compared to controls. LBN males also self-administered less morphine and had a lower breakpoint on a progressive ratio reinforcement schedule than controls. These effects of LBN on addiction-related behaviors were not found in females. Because the nucleus accumbens (NAc) mediates these behaviors, we tested whether LBN altered NAc physiology in drug-naïve and morphine-exposed rats. LBN reduced the frequency of spontaneous excitatory postsynaptic currents in males, but a similar effect was not observed in females. Only in males did LBN prevent a morphine-induced increase in the AMPA/NMDA ratio. RNA sequencing was performed to delineate the molecular signature in the NAc associated with LBN-derived phenotypes. LBN produced sex-specific changes in transcription, including in genes related to glutamate transmission. Collectively, these studies reveal that LBN causes a male-specific stress inoculation effect against addiction-related phenotypes. Identifying factors that promote resilience to addiction may reveal novel treatment options for patients.

Rural Emergency Medical Service Providers Perceptions on the Causes of and Solutions to the Opioid Crisis: A Qualitative Assessment

Introduction:

The continuing opioid crisis poses unique challenges to remote and often under-resourced rural communities. Emergency medical service (EMS) providers serve a critical role in responding to opioid overdose for individuals living in rural or remote areas who experience opioid overdoses. They are often first at the scene of an overdose and are sometimes the only health care provider in contact with an overdose patient who either did not survive or refused additional care. As such, EMS providers have valuable perspectives to share on the causes and consequences of the opioid crisis in rural communities.

Methods:

EMS providers attending a statewide EMS conference serving those from greater Minnesota and surrounding states were invited to take a 2-question survey asking them to reflect upon what they believed to be the causes of the opioid crisis and what they saw as the solutions to the opioid crisis. Results were coded and categorized using a Consensual Qualitative Research approach.

Results:

EMS providers’ perceptions on causes of the opioid crisis were categorized into 5 main domains: overprescribing, ease of access, socioeconomic vulnerability, mental health concerns, and lack of resources and education. Responses focused on solutions to address the opioid crisis were categorized into 5 main domains: need for increased education, enhanced opioid oversight, increased access to treatment programs, alternative therapies for pain management, and addressing socioeconomic vulnerabilities.

Conclusion:

Along with the recognition that the opioid crisis was at least partially caused by overprescribing, rural EMS providers who participated in this study recognized the critical role of social determinants of health in perpetuating opioid-related harm. Participants in this study reported that education and increased access to treatment facilities and appropriate pain management, along with recognition of the role of social determinants of health in opioid dependency, were necessary steps to address the opioid crisis.

Adverse Childhood Experiences Predict Early Initiation of Opioid Use Behaviors

Introduction: Although a substantial body of research documents a relationship between traumatic stress in childhood and the initiation of substance use later in the life course, only limited research has examined potential linkages between adverse childhood experiences (ACEs) and the initiation of non-medical prescription opioid use and other opioid use behaviors. The present study contributes to this growing body of work by investigating the association of childhood trauma with early initiation of a series of opioid use behaviors. Methods: New York City young adults (n = 539) ages 18-29 who reported non-medical use of prescription opioids or heroin use in the past 30 days were recruited using Respondent-Driven Sampling in 2014-16. Ten ACEs were assessed via self-report with the ACE Questionnaire. Associations between number of ACEs and self-reported ages of initiating seven opioid use behaviors (e.g., non-medical prescription opioid use, heroin use, heroin injection) were estimated with multivariable logistic regression. Results: Eighty nine percent of participants reported at least one ACE, and 46% reported four or more ACEs, a well-supported threshold indicating elevated risk for negative health consequences. Every increase of one trauma was associated with a 12-23% increase in odds of early initiation across the seven opioid use behaviors. Findings also document that the mean age at initiation increased with increasing risk severity across the behaviors, contributing to evidence of a trajectory from opioid pill misuse to opioid injection. Discussion: Increasing number of childhood traumas was associated with increased odds of earlier initiation of multiple opioid misuse behaviors. In light of prior research linking earlier initiation of substance use with increased substance use severity, present findings suggest the importance of ACEs as individual-level determinants of increased opioid use severity. Efforts to prevent onset and escalation of opioid use among at-risk youth may benefit from trauma prevention programs and trauma-focused screening and treatment, as well as increased attention to ameliorating upstream socio-structural drivers of childhood trauma.

How urban and rural built environments influence the health attitudes and behaviors of people who use drugs

Research suggests that the built environment is associated with drug use. However, there is limited scholarship focusing on specific features of the built environment that influence drug use behaviors, experiences, and patterns and how risk factors for drug use are placed in distinctive urban and rural settings. Applying Neely and Samura's conceptual theory that describes space as contested, fluid and historical, interactional and relational, and defined by inequality and difference, we assessed data from semi-structured qualitative interviews conducted between 2019 and 2020 with consumers at syringe exchange programs (SEPs) in an urban location (New York City) and a rural location (southern Illinois). We aimed to contextualize how drug use manifests in each space. In total, 65 individuals, including 59 people who use drugs (PWUD) and six professionals who worked with PWUD, were interviewed. Findings illustrate that, in both the urban and rural setting, the built environment regulates the drug use milieu by mediating social reproduction, namely the degree of agency PWUD exert to acquire and use drugs where they desire. Processes of "stigma zoning," defined as socio-spatial policing of boundaries of behavior deemed undesirable or deviant, impacted PWUD's socio-geographic mobility, social conditions, and resource access, and modulated PWUD's broader capacity and self-efficacy. Similar patterns of drug use, according to social and economic inequities chiefly related to housing instability, were further observed in both settings.

Early Life Stress and Risks for Opioid Misuse: Review of Data Supporting Neurobiological Underpinnings

A robust body of research has shown that traumatic experiences occurring during critical developmental periods of childhood when neuronal plasticity is high increase risks for a spectrum of physical and mental health problems in adulthood, including substance use disorders. However, until recently, relatively few studies had specifically examined the relationships between early life stress (ELS) and opioid use disorder (OUD). Associations with opioid use initiation, injection drug use, overdose, and poor treatment outcome have now been demonstrated. In rodents, ELS has also been shown to increase the euphoric and decrease antinociceptive effects of opioids, but little is known about these processes in humans or about the neurobiological mechanisms that may underlie these relationships. This review aims to establish a theoretical model that highlights the mechanisms by which ELS may alter opioid sensitivity, thereby contributing to future risks for OUD. Alterations induced by ELS in mesocorticolimbic brain circuits, and endogenous opioid and dopamine neurotransmitter systems are described. The limited but provocative evidence linking these alterations with opioid sensitivity and risks for OUD is presented. Overall, the findings suggest that better understanding of these mechanisms holds promise for reducing vulnerability, improving prevention strategies, and prescribing guidelines for high-risk individuals.

Associations between adolescent sleep deficiency and prescription opioid misuse in adulthood

STUDY OBJECTIVES

The main aim of this study was to estimate the association between sleep deficiency in adolescence and subsequent prescription opioid misuse in adulthood using United States nationally representative longitudinal data.

METHODS

Self-reported data captured in the National Longitudinal Study of Adolescent to Adult Health at baseline (Wave 1; mean age = 16 years) and 12 year follow-up (Wave 4; mean age = 29 years). Participants (n = 12,213) reported on four measures of sleep during adolescence (Wave 1) and on lifetime prescription opioid misuse during adulthood (Wave 4). Associations between adolescent sleep and adult opioid misuse were estimated using multivariate logistic regression analysis controlling for sociodemographics, chronic pain, mental health, childhood adverse events, and a history of substance use.

RESULTS

During adolescence, 59.2% of participants reported sleep deficiency. Prospectively, adolescents reporting not getting enough sleep, chronic unrestful sleep, and insomnia were associated with an increased risk for prescription opioid misuse (adjusted odds ratios [OR] = 1.2, p < 0.005 for all three variables). Short sleep duration was not associated with opioid misuse.

CONCLUSION

This is the first study to longitudinally link sleep deficiency as an independent risk factor for the development of prescription opioid misuse. Sleep deficiency could be a driver of the opioid crisis affecting young people in the United States. Future studies should determine whether early and targeted sleep interventions may decrease risk for opioid misuse in high-risk patients prescribed opioids for pain.

Sex differences in the effects of physical and sexual abuse on the odds of past 30-day opioid misuse among Florida justice-involved children

AIM

Opioid misuse is a severe threat to justice-involved children and adolescents. Identifying risk factors and sex differences is critical to design accurate risk assessments and person-centered interventions. Stress theory and research posit that abuse may be linked to opioid misuse, and the consequences may be harsher for females. The study tests the hypothesis that physical and sexual abuse will individually and cumulatively increase the risk for opioid misuse, and females will have a higher risk than males.

METHODS

A statewide sample of 79,960 justice-involved children in Florida were examined. Opioid misuse, illicit and non-medical use, was measured by urine analysis or self-disclosure within the past-30 days. Bivariate and multivariate logistic regression analyses were employed. Marginal effects were estimated to investigate the interaction between abuse and sex.

RESULTS

Over 2000 youth met the criteria for opioid misuse. One-third of female opioid users experienced both physical and sexual abuse. Compared to those with no history of physical or sexual abuse, those who were physically abused had 43% higher odds of opioid misuse, those who were sexually abuse had 78% higher odds, and those who experienced both had twice as high odds of opioid misuse. The individual and combined effects of these abuse types were higher for females. For example, female youth who were sexually abused had 2.7-times higher odds of opioid misuse than males who were sexually abused.

CONCLUSION

Intervention efforts can be improved by integrating physical and sexual abuse into risk assessments and tailoring assessments by sex.

Associations Between Childhood Trauma and the Age of First-Time Drug Use in Methamphetamine-Dependent Patients

Childhood trauma is related to substance use disorder; however, few studies have examined the relationship between childhood trauma and the age at which the drug was first used. The aim of this study was to investigate the relationship between childhood trauma and the age of first-time drug use among methamphetamine-dependent patients. Moreover, we analyzed the characteristics of adverse family environment associated with severe childhood trauma and the risk factors for starting drugs in minors. A baseline interview was conducted with 110 participants who were in detoxification, including demographic information, past substance use, and age of first-time drug use. The participants' childhood trauma experience before 18 years of age was evaluated using the simplified version of the Childhood Trauma Questionnaire (CTQ-SF). The Chinese version of the Family Environment Scale (FES-CV) was used to assess the family environment of methamphetamine-dependent patients. Among 110 non-injecting methamphetamine-dependent patients, nearly half (n = 48, 43.6%) had moderate and severe childhood trauma. Correlation analysis showed that the age of first-time drug use negatively correlated with emotional abuse (r = -0.32, p < 0.01) and physical abuse (r = -0.27, p < 0.01). The age of first-time drug use negatively correlated with conflict (r = -0.20, p < 0.05) and independence (r = -0.22, p < 0.05) of family environment, but positively correlated with intellectual-cultural orientation (r = 0.28, p < 0.01). Additionally, childhood trauma factors significantly correlated with many indexes of family environment, especially cohesion (r = -0.45, p < 0.01), conflict (r = 0.49, p < 0.01), and independence (r = 0.33, p < 0.01). Additionally, the regression model showed that when emotional abuse increased by one point, the age of first-time drug use was 0.69 years earlier. These findings suggest that a detrimental family environment can aggravate childhood trauma, and the experience of childhood emotional or physical abuse may be an effective predictor of early drug use among methamphetamine-dependent patients.

Associations between Childhood Abuse and Chronic Pain in Adults with Substance Use Disorders

Both childhood abuse and chronic pain are common in people with substance use disorders (SUDs). Studies have found that exposure to childhood abuse is associated with chronic pain in adulthood; however, few studies have examined this association in people with SUDs. Objectives: This study aimed to characterize the association between childhood abuse and chronic pain presence and severity in adults with SUDs. Methods: Data were obtained from 672 treatment-seeking participants with SUDs on an inpatient detoxification unit. Regression models evaluated whether childhood physical or sexual abuse was associated with the likelihood of chronic pain and severity of several pain-related characteristics: pain catastrophizing, pain severity, and pain interference. Results: Childhood physical and sexual abuse were significantly associated with a greater likelihood of chronic pain in adulthood. In the adjusted analyses, childhood physical abuse was associated with worse pain severity, whereas childhood sexual abuse was associated with greater pain catastrophizing and worse pain interference. Conclusions: Childhood physical and sexual abuse were associated with a greater likelihood of chronic pain in adults with SUDs. Among those with chronic pain, exposure to childhood abuse was associated with a more severe symptom profile, characterized by greater pain severity, more catastrophic interpretations of pain, and more pain-related interference with daily life. People with SUDs and a history of childhood abuse may benefit from screening for pain and interventions to reduce pain catastrophizing. These findings highlight the importance of longitudinal research to understand mechanisms linking childhood abuse exposure to later pain and substance misuse.

Resilience as a Mediator between Adverse Childhood Experiences and Prescription Opioid Misuse among U.S. Adults

Studies have shown some linkage between adverse childhood experiences (ACEs) and prescription opioid misuse. While preventable, once an individual is exposed to ACEs, they can have irreparable health impacts. Resilience could have protective effects on preventing those with ACEs from adulthood health-risk behaviors. Objectives: To examine how resilience mediates the association between ACEs and adulthood prescription opioid misuse among U.S. adults. Methods: Adult respondents (n = 33,613) from the National Epidemiologic Survey on Alcohol and Related Conditions-III (2012-2013) were included. A count of ten types of ACEs constituted the ACE score (range: 0-10). A latent variable was created to measure resilience based on the Connor-Davidson Resilience Scale. Generalized structural equation modeling (GSEM) was utilized to conduct the mediation analysis. The Problem Behavior Theory was used to guide covariate selection. Results: The GSEM measurement model estimated the latent variable resilience and determined that tolerance of negative effects, self-control, acceptance of change, and spiritual influence were all associated with resilience, holding personal competence constrained for estimation purposes. Respondents with a higher ACE score were more likely to misuse prescription opioids in the past year (OR = 1.08; p < 0.01), where 40.8% of the association was mediated by resilience (indirect effect OR = 1.06). Conclusion: Reducing prescription opioid misuse is an essential step in alleviating the current opioid epidemic. Findings suggested that resilience mediated the relationship between ACEs and adulthood prescription opioid misuse. To prevent adults with ACEs from misusing prescription opioids, interventions designed to address ACEs' impact should include behavioral and educational components for enhancing the priority dimensions of resilience.

The Joint Effect of Childhood Abuse and Homelessness on Substance Use in Adulthood

Childhood abuse and homelessness are independently associated with substance use. Though childhood abuse and homelessness are strongly correlated, research on the joint effect of exposure to both traumatic life events on substance use is limited. Objective: To estimate independent and joint effects of childhood abuse and homelessness on substance use risk during emerging adulthood and adulthood. Methods: Using the National Longitudinal Study of Adolescent to Adult Health (N = 12,288), we measured associations between exposure to physical or sexual abuse in childhood, homelessness in childhood or emerging adulthood, or exposure to both traumas and outcomes of binge drinking, marijuana use, cocaine use, methamphetamine use, and prescription opioid misuse during emerging adulthood (Wave III, ages 18-26 years) and adulthood (Wave IV, ages 24-32 years). Results: In adjusted analyses, exposure to childhood abuse alone, homelessness alone, and both childhood abuse and homelessness were significant correlates of most substance use indicators in emerging adulthood. Those jointly exposed to childhood abuse and homelessness had disproportionate risk of substance use, particularly use of cocaine (adjusted odds ratio (AOR)=4.25, 95% confidence interval (CI): 2.70, 6.71) and methamphetamine (AOR = 6.59, 95% CI: 3.87, 11.21). The independent and combined effects of abuse and homelessness generally persisted into adulthood though associations tended to weaken. Conclusions/Importance: Those with exposure to abuse, homelessness, and both adverse outcomes constitute a high-risk population for substance use. Addressing abuse and homelessness should be a component of preventing drug risk for screening, treatment, and prevention efforts.

Sexual Violence, Mental Health, and Prescription Opioid Use and Misuse

INTRODUCTION

Previous research indicates that sexual violence is associated with prescription opioid use and misuse. However, this literature is limited by a lack of sex-specific analyses, an inability to establish temporality between experiences of sexual violence and prescription opioid outcomes, and little understanding of mechanisms underlying these associations.

METHODS

Data from Waves IV (2008) and V (2016-2018) of the National Longitudinal Study of Adolescent to Adult Health (N=10,685) were analyzed in March 2020. The association of sexual violence with past 30-day prescription opioid use and misuse among women and men and mediation by depression and anxiety diagnoses were examined using generalized structural equation modeling. Temporality was established using self-reported age at the first experience of sexual violence and age at first depression and anxiety diagnoses.

RESULTS

Sexual violence was associated with an increased likelihood of prescription opioid use and misuse among women (OR=1.68, 95% CI=1.19, 2.39 for use; OR=1.18, 95% CI=0.95, 1.55 for misuse) and men (OR=2.37, 95% CI=1.37, 4.12 for use; OR=1.71, 95% CI=1.06, 2.75 for misuse). Among women, depression (p=0.0420) and anxiety (p=0.0450) diagnoses mediated the association with prescription opioid use, and anxiety diagnosis (p=0.0210) mediated the association with prescription opioid misuse. Among men, anxiety diagnosis (p=0.038) mediated the association with prescription opioid use, and depression diagnosis (p=0.0390) mediated the association with prescription opioid misuse.

CONCLUSIONS

Secondary prevention efforts focused on evidence-based, trauma-informed behavioral health treatment among survivors of sexual violence may prevent prescription opioid use and misuse as strategies for coping with the psychological impact of these traumatic experiences.

A life-course theory exploration of opioid-related maternal mortality in the United States

BACKGROUND AND AIMS

Between 2007 and 2016, pregnancy-associated mortality resulting from overdose more than doubled in the United States. This study explored the circumstances surrounding maternal opioid-related morbidity and mortality, using the life-course theory as a sensitizing framework to examine how each participant's life-course contributed to her substance use, relapse, recovery or overdose.

DESIGN

A mixed-methods study using semi-structured, in-depth face-to-face interviews and focus groups were conducted.

SETTING

Texas, United States.

PARTICIPANTS

Women who had relapsed into opioid use or experienced a 'near-miss' overdose and family members of women who had died during the maternal period due to opioid overdose were interviewed (n = 99).

MEASUREMENTS

A socio-demographic questionnaire captured participants' ethnicity, age, marital status, medical and mental health history and employment status. The Stressful Life Events Screening Questionnaire-revised (SLESQ-R) assessed life-time exposure to trauma.

FINDINGS

Women reported histories of abuse and loss of a loved one through homicide or suicide. Participants indicated that limited social support, interpersonal conflict with their partner and unaddressed mental illness made recovery more challenging. Additionally, losing their children through the child welfare system was described as punitive and placed them at greater risk for relapse and overdose.

CONCLUSIONS

A life-course theory approach to examining maternal opioid-related morbidity and mortality in Texas, United States reveals the complex needs of women at risk for opioid use relapse and overdose and the significant role of previous traumatic experiences.

Something to despair: Gender differences in adverse childhood experiences among rural patients

Existing research has demonstrated that patients in treatment for an opioid use disorder (OUD) have high rates of adverse childhood experiences (ACE) compared to community-based samples. While research has documented important gender differences in ACEs in patients with OUD receiving treatment in urban areas, research has not shown whether these findings would generalize to rural and Appalachian areas, which are known to have lower ACE scores. We conducted a secondary analysis of existing clinical data, utilizing intake assessment data from a rural Appalachian outpatient buprenorphine program. We restricted the sample to patients with an OUD who presented for treatment between June 2018 and June 2019 (n = 173). The clinical intake assessment included a modified 17-item ACE instrument that patients self-administered. More than half (54.3%) of patients reported having experienced 4+ categories of adverse childhood experiences. On average, females endorsed 4.5 categories of adverse experiences, whereas males endorsed 3.3 (p < 0.00); female patients were significantly more likely to have experienced sexual abuse (42.4% versus 10.6%, p < 0.00). Alarmingly, 25.9% of females and 8.2% of males reported being forced to have sex before age 18. Disproportionately high rates of childhood adversities, particularly among females, may partially explain despair in rural Appalachian areas. OUD treatment programs should conduct clinical assessments of trauma and integrate trauma-informed care into drug treatment, especially for female patients residing in rural Appalachia.

Exploring stress, cognitive, and affective mechanisms of the relationship between interpersonal trauma and opioid misuse

BACKGROUND

People with a history of interpersonal trauma, including intimate partner violence, sexual assault, and adverse childhood experiences, are disproportionately affected by the current opioid epidemic. Interpersonal trauma has been shown to increase risk for chronic pain conditions, prescription opioid use, and opioid misuse. Stress, cognition, and affective function have been examined as potential mechanisms that may influence opioid misuse among individuals with a history of interpersonal trauma. However, no studies have examined these factors simultaneously, despite their interrelatedness.

OBJECTIVE

The purpose of this study was to 1) examine perceived stress, perceived cognitive function, depressive symptoms, and PTSD symptoms as potential mechanisms of opioid misuse among individuals with a history of interpersonal trauma, 2) examine the types of interpersonal trauma that are associated with opioid misuse, and 3) assess the mediating role of pain and opioid prescription.

METHODS

A cross-sectional, observational study design was conducted. Data were collected through a confidential self-report online survey using validated instruments (n = 230). A series of regression analyses were conducted to identify mechanistic factors and interpersonal trauma types associated with opioid misuse, opioid prescription, and pain intensity. Structural equation modeling was used to examine mediating effects of pain intensity and opioid prescription.

RESULTS

Opioid prescription, depressive symptoms, and intimate partner violence increased the odds of reporting opioid misuse. Pain intensity and adverse childhood experiences increased the odds of opioid prescription. Higher levels of perceived stress and depressive symptoms were associated with increased pain intensity. Pain intensity emerged as a mediator of the relationship between depressive symptoms and opioid misuse.

CONCLUSIONS

Our work shows that there are likely several pathways through which interpersonal trauma can lead to opioid misuse. Interventions aimed at improving depressive symptoms and coping with traumatizing events should be included as part of comprehensive trauma-informed pain management practices.

The Opioid Epidemic: Task-Shifting in Health Care and the Case for Access to Harm Reduction for People Who Use Drugs

We are sadly experiencing unprecedented levels of overdose mortalities attributed to the increased availability of synthetic opioids in illegal markets. While the majority of attention in North America has focused on preventing drug overdose cases through the distribution and administration of naloxone, in addition to stricter regulations of opioid prescriptions and greater law enforcement in illegal markets, little attention has been given to other alternative models and treatments for people who use drugs that are tailored specifically to the health care needs of this marginalized population. Through this analysis, the implications of task-shifting in health care via the distribution of naloxone for an already marginalized population are discussed. Alternatively, the role of pioneering harm-reduction programs - such as supervised injection/consumption sites, a variety of opioids maintenance therapies, and social-structural interventions - are highlighted as crucial interventions in the current ongoing opioid crisis. Moreover, people with lived experiences of illegal drug use are discussed as having a pivotal role but being ultimately overshadowed by public health partners.

Re-assessing the Validity of the Opioid Risk Tool in a Tertiary Academic Pain Management Center Population

OBJECTIVE

To analyze the validity of the Opioid Risk Tool (ORT) in a large. diverse population.

DESIGN

A cross-sectional descriptive study.

SETTING

Academic tertiary pain management center.

SUBJECTS

A total of 225 consecutive new patients, aged 18 years or older.

METHODS

Data collection included demographics, ORT scores, aberrant behaviors, pain intensity scores, opioid type and dose, smoking status, employment, and marital status.

RESULTS

In this population, we were not able to replicate the findings of the initial ORT study. Self-report was no better than chance in predicting those who would have an opioid aberrant behavior. The ORT risk variables did not predict aberrant behaviors in either gender group. There was significant disparity in the scores between self-reported ORT and the ORT supplemented with medical record data (enhanced ORT). Using the enhanced ORT, high-risk patients were 2.5 times more likely to have an aberrant behavior than the low-risk group. The only risk variable associated with aberrant behavior was personal history of prescription drug misuse.

CONCLUSIONS

The self-report ORT was not a valid test for the prediction of future aberrant behaviors in this academic pain management population. The original risk categories (low, medium, high) were not supported in the either the self-reported version or the enhanced version; however, the enhanced data were able to differentiate between high- and low-risk patients. Unfortunately, without technological automation, the enhanced ORT suffers from practical limitations. The self-report ORT may not be a valid tool in current pain populations; however, modification into a binary (high/low) score system needs further study.

Drivers of opioid use in Appalachian Pennsylvania: Cross-cutting social and community-level factors

BACKGROUND

Four Appalachian states including Pennsylvania (PA) have the highest drug overdose rates in the country, calling for better understanding of the social and economic drivers of opioid use in the region. Using key informant interviews, we explored the social and community drivers of opioid use in a non-urban Appalachian Pennsylvania community.

METHODS

In 2017, we conducted qualitative interviews with 20 key stakeholders from a case community selected using the results from quantitative spatial models of hospitalizations for opioid use disorders. In small town located 10 miles outside Pittsburgh, PA, we asked participants to share their perceptions of contextual factors that influence opioid use among residents. We then used qualitative thematic analysis to organize and generate the results.

RESULTS

Participants identified several contextual factors that influence opioid use among residents. Three cross-cutting thematic topics emerged: 1) acceptance and denial of use through familial and peer influences, community environments, and social norms; 2) impacts of economic shifts and community leadership on availability of programs and opportunities; and 3) the role of coping within economic disadvantage and social depression.

CONCLUSION

Uncovering multi-level, contextual drivers of opioid use can benefit the development of future public health interventions. These results suggest that social and community-level measures of structural deprivation, acceptance and/or denial of the opioid epidemic, community engagement and development, social support, and social depression are important for future research and programmatic efforts in the Appalachian region.

Factors associated with benzodiazepine prescribing in community mental health settings

OBJECTIVE

One class of drugs increasingly involved in overdose fatalities is benzodiazepines. Prescribing benzodiazepines to people with co-occurring substance use disorders (SUDs) poses risk for overdose and dependence and is not recommended. The current study reports prevalence rates of prescribing benzodiazepines to people with and without co-occurring SUDs in community mental health settings. Clinical and socio-demographic factors associated with receipt of a benzodiazepine were examined, including whether factors potentially indicative of prescribing biases (older age and race) moderated the relationship between having a co-occurring SUD and receiving a benzodiazepine prescription.

METHODS

Retrospective chart review data from service users treated between August 2014 and August 2017 were collected as part of an NIMH-funded RCT of Person-Centered Care Planning. Data were assessed from 774 charts collected across 14 sites nested within ten community mental health centers (CMHCs). Mixed effects logistic regression models examined direct and interaction effects related to receipt of a benzodiazepine.

RESULTS

Of the 774 service users, 19.9% (N = 154) were prescribed at least one benzodiazepine. Of those prescribed a benzodiazepine, 35.1% (N = 54) had a co-occurring SUD and 31.8% (N = 49) had an anxiety disorder. Our main effects model did not find a significant difference in the odds of receiving a benzodiazepine among service users with and without a co-occurring SUD (OR = 0.77, CI: 0.50-1.17). However, moderation analyses found that the odds of being prescribed a benzodiazepine among people with co-occurring SUDs was greater among service users of older age (OR: 2.01, CI: 1.01-4.02) and non-Hispanic white race (OR = 3.34, CI: 1.55-7.22).

DISCUSSION

Our findings demonstrate that a considerable number of people with a documented co-occurring SUD are prescribed benzodiazepines in CMHCs, a practice that poses risks for dependence and overdose. Prescribing decisions may be influenced by service user age and race.

Adapting the Social-Ecological Framework for Chronic Pain Management and Successful Opioid Tapering

Context

In 2015, Solano County's Medi-Cal insurer implemented a new policy to taper patients using high-dose opioids (≥120-mg morphine equivalent dose) to a safer level to follow best practices to address the opioid epidemic.

Objective

To evaluate the effect of the 2015 Solano County Medi-Cal prescribing policy, gain insight into the patient experience of undergoing opioid tapering, and generate hypotheses for further study.

Methods

Using a case series approach, researchers completed medical record reviews of affiliated clinical records, Solano County Vital Statistics, and California's prescription monitoring program in 2018. After exclusions, eligible patients were asked to participate in a comprehensive qualitative interview.

Results

Medical record reviews of 38 patients found the majority were not using opioids using them at a morphine equivalent dose of 90 mg or less. The reviews also found that mental illness and obesity prevalence were higher than Solano county baseline levels. Furthermore, naloxone was not prescribed to any of the 38 patients. Researchers reached 15 of the 38 patients by phone, and ultimately 6 completed the interview process. Themes and emergent concepts from interviews identified a lack of empathetic connection with health care professionals, poor understanding of overdose risks, persistent pain, and confirmed naloxone underuse.

Conclusion

Safer prescribing policies may take multiple years to fully implement and need to be employed across the jurisdiction to minimize doctor-shopping and adverse effects on patients with chronic pain. Approaching pain management through the social-ecological model can address potential root causes of addiction and establish a framework for doctors to provide compassionate care, community leadership, and advocacy for these patients.

Childhood abuse as a risk factor for injection drug use: A systematic review of observational studies

ISSUES

Childhood abuse is a public health challenge with lifelong impacts, including future drug use. However, previous research has been mixed regarding impacts on injection drug use. This systematic review examines the impact of childhood abuse (sexual, physical and emotional) on adult injection drug use.

APPROACH

We searched MEDLINE, EMBASE, PsycINFO, CINAHL, Web of Science and grey literature to identify relevant studies from database inception to 26 September 2018. Studies were eligible if: (i) they were empirical original research published in English; (ii) considered childhood abuse as potential risk factors for lifetime history of injection drug use; and (iii) included adult participants. Risk of bias was assessed using the modified Newcastle-Ottawa Scale.

KEY FINDINGS

Of the 1994 articles screened, 17 studies met the inclusion criteria. Most studies were conducted in the USA and utilised cross-sectional research designs. All of the 17 studies measured sexual abuse, six studies measured physical abuse and three studies measured emotional abuse; most (N = 11) of which reported a statistically significant and positive association between at least one sub-scale of childhood abuse and injection drug use.

IMPLICATIONS

Our findings highlight the need for devising interventions to reduce the harms associated with childhood abuse.

CONCLUSIONS

The evidence base suggests a significant positive association between experiences of childhood physical abuse and elevated risks of injection drug initiation with mixed results for sexual and emotional abuse.

Direct and indirect associations between perception of childhood trauma and suicidal ideation through emotion dysregulation in males who use heroin

Emotion dysregulation is considered as one of the factors related to suicide in individuals with childhood trauma (CT). However, no research has been performed on the role of emotion dysregulation in the relationship between perception of CT and suicidal ideation in individuals who use heroin. This study aimed to evaluate direct and indirect relationships between perception of CT and suicidal ideation through emotion regulation difficulties (ERD) and cognitive emotion regulation strategies (CERSs) in males with a DSM diagnosis of heroin dependence. In a cross-sectional design, 310 males with a DSM diagnosis of heroin dependence completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Difficulties in Emotion Regulation Scale (DERS), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Obsessive-Compulsive Drug Use Scale-Form Heroin (OCDUS-Form Heroin), and the Depression Anxiety Stress Scales (DASS). The results revealed that perception of CT had no direct relation to suicidal ideation. Perception of CT was indirectly associated with suicidal ideation through some ERD dimensions [e.g., non-acceptance of emotional responses (Non-acceptance), limited access to emotion regulation strategies (Strategies), lack of emotional awareness (Awareness)] and the CERS of positive reappraisal. The findings suggest that high suicidal ideation may stem from a perception of CT and subsequently emotion dysregulation in individuals who use heroin. Also, the findings of this research may have implications for the prevention and treatment of suicidal ideation in individuals using heroin with a perception of CT. The results of the present study require further examination through longitudinal studies.

Effects of childhood emotional maltreatment on depressive symptoms through emotion dysregulation in treatment-seeking patients with heroin-dependence

BACKGROUND

Although individuals who experience childhood emotional maltreatment (CEM) are more likely to use maladaptive emotion regulation strategies, resulting in vulnerability to depression, no research has examined whether emotion dysregulation may explain the association between CEM and current depressive symptoms in a clinical sample of heroin-dependent individuals.

OBJECTIVES

The current study aimed to assess the direct effect of CEM on current depressive symptoms and its indirect effect via emotion dysregulation in a treatment-seeking sample of males with heroin dependence. In a cross-sectional design, participants (N = 350) completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Difficulties in Emotion Regulation Scale (DERS), the Obsessive-Compulsive Drug Use Scale (OCDUS), and the Beck Depression Inventory-II (BDI-II).

RESULTS

Emotional abuse and neglect severity had significant direct effects on current depressive symptoms and significant indirect effects through emotion dysregulation after controlling for clinical factors related to heroin use.

LIMITATIONS

Study limitations include the cross-sectional design and use of self-report scales.

CONCLUSIONS

Findings suggest emotion dysregulation may increase depressive symptoms in heroin users who experienced CEM. Training in emotion regulation strategies may decrease depressive symptoms in heroin-dependent individuals with CEM. Additional research with a longitudinal design to confirm these results is warranted.

Gender and Race Informed Pathways From Childhood Sexual Abuse to Sexually Transmitted Infections: A Moderated Mediation Analysis Using Nationally Representative Data

PURPOSE

Although data suggest child sexual abuse is linked with increased risk of contracting asexually transmitted infection (STI), the mechanisms through which these experiences are connected remain understudied. Moreover, there is a need to explore how race/ethnicity and gender influence these processes.

METHODS

The present study examined the mediational pathways from child sexual abuse to risky sexual behavior to STIs and further evaluated the role of depressive symptomatology and nonmedical prescription drug use on the relationship between child sexual abuse and risky sexual behavior. In addition, race and gender were examined as moderators to account for potential different effects of these mechanisms on females and males and on different racial and ethnic groups. A nationally representative sample of 4,181 youth from the Add Health dataset was used.

RESULTS

Results from a moderated mediation model indicated risky sexual behavior partially mediated the pathway from child sexual abuse to STI contraction and depressive symptomatology and nonmedical prescription drug use partially mediated pathway from child sexual abuse to risky sexual behavior. Race and gender moderated the relationship between risky sexual behavior and STI contraction.

CONCLUSIONS

Findings underscore the need for STI prevention efforts among adolescents to focus on risk factors beyond risky sexual behaviors, such as childhood sexual abuse and mental health screening that includes depressive symptomatology and nonmedical prescription drug use. In addition, findings emphasize the need to further examine the different effects on different racial/ethnic and gender subgroups, particularly black women.

The Association of Trauma with the Physical, Behavioral, and Social Health of Women Living with HIV: Pathways to Guide Trauma-informed Health Care Interventions

BACKGROUND

Trauma is increasingly recognized as a near-universal experience among women living with HIV (WLHIV) and a key contributor to HIV acquisition, morbidity, and mortality.

METHODS

We present data from the baseline analysis of a planned intervention trial of the impact of trauma-informed health care on physical, behavioral, and social health outcomes of WLHIV in one clinic, with a particular focus on quality of life and viral suppression. Data were collected through interviewer-administered surveys and electronic health record data abstraction.

RESULTS

Among 104 WLHIV, 97.1% of participants reported having experienced lifetime trauma, and participants had experienced on average 4.2 out of 10 Adverse Childhood Experiences. WLHIV with more lifetime trauma were significantly more likely to report post-traumatic stress disorder, depression, and anxiety symptoms; significantly more likely to report potentially harmful alcohol and drug use; and had a significantly poorer quality of life. In addition, women who had experienced more lifetime trauma were significantly less likely to report being on and adhering to HIV medications, although trauma was not significantly associated with having an undetectable HIV viral load.

CONCLUSIONS

These data suggest that trauma is associated with much of the morbidity and mortality experienced by WLHIV. The results of this study support the implementation and study of trauma-informed approaches to health care for WLHIV.
