Prospective associations of family conflict with alcohol expectancies in the adolescent brain cognitive development study: effects of race and ethnicity.

Introduction: Alcohol expectancies predict subsequent alcohol use and related problems among adolescents, although predictors of alcohol expectancies remain unclear. This study examined the longitudinal association between family conflict, a sociocultural factor strongly implicated in adolescent alcohol use, and positive and negative alcohol expectancies of adolescents of diverse racial/ethnic backgrounds. Methods: Data were from the Adolescent Brain Cognitive Development Study 4.0 release, a multisite longitudinal study (N = 6,231, baseline age 9-10). Linear mixed-effects regression, with interactions between race/ethnicity and family conflict, tested the association between family conflict and alcohol expectancies, for each racial/ethnicity (e.g., Black vs. non-Black; White vs. non-White). Results: Interactions of family conflict with race/ethnicity in predicting negative and positive alcohol expectancies were statistically significant for models testing Black and White adolescents, but not for Asian, Hispanic, and Other. Family conflict at baseline predicted lower negative alcohol expectancy for Black adolescents (B = -.166, p = 0.033) and positive alcohol expectancy for White adolescents (B = 0.71, p = 0.023) at the year 3 follow-up. All models controlled for sex, age, family socioeconomic status, alcohol expectancies at year 1, and family conflict at year 3. Conclusion: The results indicate that family conflict is a potential risk factor for problematic alcohol expectancies for Black and White adolescents. Although we did not directly compare Black and White adolescents, our findings indicate that family conflict may operate differently for Black and White adolescents. Prevention and intervention efforts targeting family conflict may be relevant for different aspects of alcohol expectancies in Black and White families.

Associations Between Family History of Alcohol and/or Substance Use Problems and Frontal Cortical Development From 9 to 13 Years of Age: A Longitudinal Analysis of the ABCD Study.

Background: Previous investigations that have examined associations between family history (FH) of alcohol/substance use and adolescent brain development have been primarily cross-sectional. Here, leveraging a large population-based sample of youths, we characterized frontal cortical trajectories among 9- to 13-year-olds with (FH+) versus without (FH-) an FH and examined sex as a potential moderator. Methods: We used data from 9710 participants in the Adolescent Brain Cognitive Development (ABCD) Study (release 4.0). FH+ was defined as having ≥1 biological parents and/or ≥2 biological grandparents with a history of alcohol/substance use problems (n = 2433). Our primary outcome was frontal cortical structural measures obtained at baseline (ages 9-11) and year 2 follow-up (ages 11-13). We used linear mixed-effects models to examine the extent to which FH status qualified frontal cortical development over the age span studied. Finally, we ran additional interactions with sex to test whether observed associations between FH and cortical development differed significantly between sexes. Results: For FH+ (vs. FH-) youths, we observed increased cortical thinning from 9 to 13 years across the frontal cortex as a whole. When we probed for sex differences, we observed significant declines in frontal cortical thickness among boys but not girls from ages 9 to 13 years. No associations were observed between FH and frontal cortical surface area or volume. Conclusions: Having a FH+ is associated with more rapid thinning of the frontal cortex across ages 9 to 13, with this effect driven primarily by male participants. Future studies will need to test whether the observed pattern of accelerated thinning predicts future substance use outcomes.

Examining Gender Differences in the Relationship Between School Bonding and Opioid Misuse Among Justice-Involved Adolescents.

Justice-involved adolescents (JIAs) have an increased risk for opioid use disorder and overdose related to opioid misuse (OM). Consequences of untreated OM include recidivism and poor educational outcomes, which can be harsher for female JIA. Therefore, identifying relevant factors and settings that reduce the risk for OM is critical. Schools are a central institution in adolescent development. Drawing on social control theory, JIA with higher levels of school bonding was hypothesized to attenuate risk for OM. Cross-sectional data on 79,960 JIA from the Florida Department of Juvenile Justice were examined. Multivariate and stratified logistic regression analyses were employed. On average, for every one-unit increase in school bonding, JIA had 22%, female JIA had 23%, and male JIA had 22% lower odds of OM. Results suggest school bonding and the school context should be considered in treatment and how this setting may impact OM intervention outcomes among JIA.

Effects of parental mental health and family environment on impulsivity in preadolescents: a longitudinal ABCD study®.

Introduction: Impulsivity is a known risk factor for the development of substance use disorders and other psychiatric conditions that is influenced by both genetics and environment. Although research has linked parental mental health to children's impulsivity, potential mediators of this relationship remain understudied. The current investigation leverages the large national Adolescent Brain Cognitive Development (ABCD) Study to assess the mediating role of family conflict - an important social context for youth development - in the relationship between parental mental health and youth impulsivity. Methods: Data were from the first three annual waves of the ABCD study (Baseline N = 11,876 children, Mage = 9.9 years; 48% female; 52% White). Parental mental health conditions were self-reported internalizing, externalizing, and total problems. Youth completed the family conflict scale, and Urgency, Planning (lack of), Perseverance (lack of), Sensation Seeking, and Positive Urgency (UPPS-P) scale to measure impulsivity. To determine if within-family change in conflict from baseline to year 1 explained changes in the strength of relations between baseline parental mental health and year 2 youth impulsivity, longitudinal causal mediation analyses were conducted, controlling for demographic factors (i.e., age, sex, race, household income, parental education, marital status), as well as baseline levels of family conflict and outcomes. Separate mediation models were run for each mental health condition and each UPPS-P subscale. Results: Above and beyond bivariate relations, longitudinal mediation models, which included covariates, showed family conflict significantly (ps < 0.001) mediated relations between all three parental mental health conditions and all but one (i.e., sensation seeking) UPPS-P subscales. The proportion mediated through family conflict for internalizing problems and total problems on facets of impulsivity (except sensation seeking) ranged from 9% (for lack of perseverance) to 17% (for lack of planning). Proportion mediated via family conflict for externalizing problems on youth's impulsivity (except sensation seeking) was slightly higher, ranging between 13% (lack of perseverance) to 21% (lack of planning). Discussion: Family conflict may be an important intergenerational factor linking parental mental health and youth's impulsivity. Addressing parental mental health and family conflict may help curb increased impulsivity in youth, and in turn reduce adolescent substance use disorders.

Single Cell Transcriptome of Stress Vulnerability Network in mouse Prefrontal Cortex.

Increased vulnerability to stress is a major risk factor for the manifestation of several mood disorders, including major depressive disorder (MDD). Despite the status of MDD as a significant donor to global disability, the complex integration of genetic and environmental factors that contribute to the behavioral display of such disorders has made a thorough understanding of related etiology elusive. Recent developments suggest that a brain-wide network approach is needed, taking into account the complex interplay of cell types spanning multiple brain regions. Single cell RNA-sequencing technologies can provide transcriptomic profiling at the single-cell level across heterogenous samples. Furthermore, we have previously used local field potential oscillations and machine learning to identify an electrical brain network that is indicative of a predisposed vulnerability state. Thus, this study combined single cell RNA-sequencing (scRNA-Seq) with electrical brain network measures of the stress-vulnerable state, providing a unique opportunity to access the relationship between stress network activity and transcriptomic changes within individual cell types. We found especially high numbers of differentially expressed genes between animals with high and low stress vulnerability brain network activity in astrocytes and glutamatergic neurons but we estimated that vulnerability network activity depends most on GABAergic neurons. High vulnerability network activity included upregulation of microglia and mitochondrial and metabolic pathways, while lower vulnerability involved synaptic regulation. Genes that were differentially regulated with vulnerability network activity significantly overlapped with genes identified as having significant SNPs by human GWAS for depression. Taken together, these data provide the gene expression architecture of a previously uncharacterized stress vulnerability brain state, enabling new understanding and intervention of predisposition to stress susceptibility.

Homegrown: Parent and Sibling Substance Abuse Linked to Opioid Misuse Among Justice-Involved Children.

Opioid misuse (OM) is a priority public health concern, especially for those in correctional settings. Understanding the etiology of OM among justice-involved children (JIC) is key to resolving this crisis. On average, 12% of all children and up to 50% of JIC in the United States have experienced household substance misuse (HSM). Theory and empirical research suggest that HSM may increase risk for OM, but these relationships have not been examined among JIC. The objective of this study was to examine the effects of sibling and parent substance misuse on OM among JIC. Cross-sectional data on 79,960 JIC from the Florida Department of Juvenile Justice (FLDJJ) were examined. Past 30-day opioid (P30D) OM was indicated by urine analysis. Bivariate and multivariate logistic regression analyses were employed. In the total sample, nearly 3% met FLDJJ criteria for P30D OM and nearly 25% lived with a parent/caregiver or sibling who misused substances. Among opioid misusers, one third lived with a parent/caregiver who misused substances and nearly half lived with a parent/caregiver or sibling who misused substances. Compared to JIC without HSM, JIC reporting sibling substance misuse had 1.95 times higher odds of OM (95% CI, 1.63-2.33), JIC with parent substance misuse had over twice the odds of OM (95% CI, 1.89-2.31), and those with both sibling and parent had more than three times higher odds of OM (95% CI, 2.75-3.87). Family-based approaches to OM intervention and prevention initiatives may be more effective than individual-focused approaches. Implications are discussed.

The Inflation Reduction Act: How Will Medicare Negotiating Drug Prices Impact Patients with Heart Disease?

PURPOSE OF REVIEW: Cardiovascular medications improve health and prevent early death. However, high drug prices reduce the use of these medications and strain the health system. The Inflation Reduction Act (IRA) of 2022 allows Medicare to negotiate drug prices with manufacturers and reduces out-of-pocket drug costs for Medicare beneficiaries. This article explores the potential impact that the IRA will have on the treatment of cardiovascular disease. RECENT FINDINGS: Cardiovascular disease medications are likely to be selected for price negotiations under the IRA, leading to savings for patients and for Medicare. Recent work suggests that the IRA's reforms to the Medicare Part D drug benefit will meaningfully reduce out-of-pocket costs for important cardiovascular medications. The IRA is expected to impact cardiovascular disease treatments via price negotiations and through the broader access to medications afforded by improvements to Part D coverage design.

Racial/Ethnic Differences in the Effects of Adverse Childhood Experiences on Substance Misuse among Justice-Involved Children.

Background: Adverse childhood experiences (ACEs) are linked to substance use (SU) and substance use disorders (SUD). However, this relationship has yet to be tested among justice-involved children (JIC), and it is unclear if racial/ethnic differences exist. This study aimed to determine: (1) whether ACEs are associated with increased risk of SU and SUD among JIC; and (2) if the effects of ACEs on SU and SUD are moderated by race/ethnicity. Methods: Bivariate and multivariate logistic regression analyses were employed to examine a statewide dataset of 79,960 JIC from the Florida Department of Juvenile Justice. Marginal odds were estimated to examine how race moderates the relationship between ACEs and SU and SUD. Results: Results showed higher ACEs scores were linked to SU and SUD. Black JIC were 2.46 times more likely, and Latinx JIC were 1.40 times more likely to report SU than white JIC. Specifically, Black and Latinx JIC with a higher average ACEs score were more likely to report SU but less likely to have ever been diagnosed with a SUD when compared to white JIC with equivalent ACEs. Conclusions: Study results highlight the need to develop trauma-informed and culturally appropriate interventions for SU and SUD among JIC.

The nexus between gender, parental supervision, and opioid misuse among justice-involved adolescents.

Justice-involved adolescents (JIA) are at higher risk for opioid misuse (OM) and opioid-related overdose than nonoffending adolescents. Untreated OM can lead to severe consequences (e.g., trauma), which may be harsher for female JIA. Therefore, examining risk and protective factors, such as parental supervision, is essential to identify factors that may impact OM. The current study used a statewide, cross-sectional dataset including 79,960 JIA from the Florida Department of Juvenile Justice. Stratified logistic regression analyses were conducted. Results indicated that JIA who experienced sporadic or inadequate supervision had 2.14 and 3.54 higher odds, respectively, of misusing opioids compared to JIA who experienced consistent supervision. Female JIA who experienced sporadic or inadequate supervision had 2.23 and 3.70 higher odds, respectively, of misusing opioids. Results suggest parental supervision is an important protective factor that should be considered in developing prevention and treatment efforts that serve JIA who misuse opioids, especially females.

Black girls and referrals: racial and gender disparities in self-reported referral to substance use disorder assessment among justice-involved children.

BACKGROUND: There is a higher prevalence of substance use disorder (SUD) among justice-involved children (JIC). It is critical to ensure that JIC who report current use are referred for SUD assessment and potentially life-saving treatment services. Prior research suggests that certain minoritized groups may be less likely to have ever been referred for screening, and research on intersectionality suggests that these disparities may be exacerbated for racially minoritized females. METHODS: Multivariate logistic regression and interaction effects were employed to analyze longitudinal data from the Florida Department of Juvenile Justice on 12,128 JIC who reported SU in the past 6 months. The main and interaction effects of race and gender on the odds of having a history of reporting a referral to SUD assessment were tested. The primary outcome variable was a self-reported measure of a youth's history of being referred to service. The control variables included substance type, household income, current SU problems, history of mental health problems, number of misdemeanors, risk to recidivate, and age at first offense. RESULTS: There were no significant differences in the likelihood of having a history of reporting being referred to SUD assessment between White females, White males, and Latinx females. However, Black females (AOR = 0.62), Latinx males (AOR = 0.71), and Black males (AOR = 0.65) were significantly less likely to self-report having a history of being referred than White males. Black females were 34% likely to report a history of being referred as White males and females. CONCLUSION: In this sample, Black females who use substances were substantially less likely to self-report being referred to SUD screening. According to officials, FLDJJ has solid process to ensure referrals are made. Therefore, the results are likely to be due to external factors and alternative explanations. Community leaders and stakeholders may consider culturally relevant and gender-sensitive programs to expand access to services for minoritized adolescents in their communities, schools, and other institutions.

Primary Purpose for Committing a Crime and Past-30 Day Opioid Misuse: A Statewide Sample of Justice-Involved Children.

The prevalence of opioid misuse (OM) among justice-involved children (JIC) is significantly higher than children in the general population, yet little research has examined the predictors of OM among JIC. Goldstein's "economic compulsive model" hypothesizes that JIC who commit crimes for material gain will have a higher likelihood of meeting past-30 day (P30D) OM criteria. The data in this study were cross-sectional and represented 79,960 Florida JIC. To test the hypothesis, logistic regression analyses were utilized. Over 2000 JIC (2.67%) met P30D OM criteria and JIC who committed crimes for material gain were 2.55 times as likely to meet P30D OM criteria. Findings indicate that children may be incarcerated due to an inability to afford their addiction, contributing to the criminalization of mental health. JIC could benefit from the increased utilization of drug courts and the implementation of a cascade of care model.

Preventing Adolescent Opioid Misuse: Racial/Ethnic Differences in the Protective Effects of Extracurricular Activities.

OBJECTIVE: Participation in extracurricular activities has been largely shown to be protective against adolescent substance use. However, research has yet to examine whether extracurricular activities are specifically protective against adolescent opioid misuse and if these protective effects vary by race/ethnicity. This study focuses on a high-risk population for drug use (i.e., justice-involved adolescents [JIAs]) that is not often captured in population-based surveys. The goals of the current study were twofold: (a) determine the prevalence of opioid misuse for White, Black, and Latinx JIAs and (b) assess the influence of participation in extracurricular activities on opioid misuse risk among White, Black, and Latinx JIAs. METHOD: Using data from the Florida Department of Juvenile Justice (n = 65,248), multivariate logistic regression models were estimated to determine which racial/ethnic groups experienced protective effects from participation in extracurricular activities. RESULTS: Results show that 2.3% of the sample met criteria for past-30-day opioid misuse and participation in extracurricular activities lowered the risk for opioid misuse by 36%. However, although involvement in extracurricular activities was protective for White and Latinx youth, Black youth received no such protective effect. CONCLUSIONS: This study provides evidence of a fairly strong protective effect (36% risk reduction) for extracurricular activities against opioid misuse, but our results caution against assuming that youth from all racial/ethnic backgrounds benefit similarly from extracurricular activities because Black adolescents may not experience the same protective benefit that White and Latinx youth receive. Programs should be aware that the protection extracurricular activities offer varies across racial/ethnic lines and tailoring may be warranted to see protective effects for Black youth.

Sex differences in the association of adverse childhood experiences on past 30-day opioid misuse among Florida justice-involved children.

INTRODUCTION: Opioid misuse remains a chief public health concern in the United States, especially among justice-involved children and adolescents (JIC). Adverse childhood experiences (ACEs) are prevalent among JIC and are associated with a higher risk for opioid misuse. Justice involvement can be harsher for females, who tend to have higher ACE scores and experience more physiological and psychological risk factors than males. However, this study was the first to examine how sex may moderate the link between ACEs and opioid misuse. This study hypothesized that females will have higher odds of opioid misuse than males with equivalent ACEs. METHODS: The study team examined cross-sectional data on 79,960 JIC in the Florida Department of Juvenile Justice from 2007 to 2015. The study measured ACEs using 10 questions from the Positive Achievement Change Tool. Opioid misuse was reported by either self-disclosure, positive urinalysis, or other evidence of opioid consumption within the past 30 days. The team estimated logistic regression, marginal effects, and multiplicative interaction terms to test the hypotheses. RESULTS: JIC with an ACE score of 4 or higher were 2.59 times more likely to misuse opioids than JIC with lower ACE scores. Among JIC with 4 or more ACEs, females had significantly higher odds of opioid misuse than males. CONCLUSION: Reducing exposure to ACEs may decrease the risk for opioid misuse, particularly among females. These findings corroborate trauma-informed and sex-responsive prevention programs in the juvenile justice system.

Ultrasonic Deep Brain Neuromodulation in Acute Disorders of Consciousness: A Proof-of-Concept.

The promotion of recovery in patients who have entered a disorder of consciousness (DOC; e.g., coma or vegetative states) following severe brain injury remains an enduring medical challenge despite an ever-growing scientific understanding of these conditions. Indeed, recent work has consistently implicated altered cortical modulation by deep brain structures (e.g., the thalamus and the basal ganglia) following brain damage in the arising of, and recovery from, DOCs. The (re)emergence of low-intensity focused ultrasound (LIFU) neuromodulation may provide a means to selectively modulate the activity of deep brain structures noninvasively for the study and treatment of DOCs. This technique is unique in its combination of relatively high spatial precision and noninvasive implementation. Given the consistent implication of the thalamus in DOCs and prior results inducing behavioral recovery through invasive thalamic stimulation, here we applied ultrasound to the central thalamus in 11 acute DOC patients, measured behavioral responsiveness before and after sonication, and applied functional MRI during sonication. With respect to behavioral responsiveness, we observed significant recovery in the week following thalamic LIFU compared with baseline. With respect to functional imaging, we found decreased BOLD signals in the frontal cortex and basal ganglia during LIFU compared with baseline. In addition, we also found a relationship between altered connectivity of the sonicated thalamus and the degree of recovery observed post-LIFU.

Neural oscillations track recovery of consciousness in acute traumatic brain injury patients.

Electroencephalography (EEG), easily deployed at the bedside, is an attractive modality for deriving quantitative biomarkers of prognosis and differential diagnosis in severe brain injury and disorders of consciousness (DOC). Prior work by Schiff has identified four dynamic regimes of progressive recovery of consciousness defined by the presence or absence of thalamically-driven EEG oscillations. These four predefined categories (ABCD model) relate, on a theoretical level, to thalamocortical integrity and, on an empirical level, to behavioral outcome in patients with cardiac arrest coma etiologies. However, whether this theory-based stratification of patients might be useful as a diagnostic biomarker in DOC and measurably linked to thalamocortical dysfunction remains unknown. In this work, we relate the reemergence of thalamically-driven EEG oscillations to behavioral recovery from traumatic brain injury (TBI) in a cohort of N = 38 acute patients with moderate-to-severe TBI and an average of 1 week of EEG recorded per patient. We analyzed an average of 3.4 hr of EEG per patient, sampled to coincide with 30-min periods of maximal behavioral arousal. Our work tests and supports the ABCD model, showing that it outperforms a data-driven clustering approach and may perform equally well compared to a more parsimonious categorization. Additionally, in a subset of patients (N = 11), we correlated EEG findings with functional magnetic resonance imaging (fMRI) connectivity between nodes in the mesocircuit-which has been theoretically implicated by Schiff in DOC-and report a trend-level relationship that warrants further investigation in larger studies.
