“Behavioral addictions” share biological mechanisms with substance dependence, and “drug interactions” have been observed between certain substances and self-reinforcing behaviors. This study examines correlates of patterns of and motivations for playing video games while using or feeling the effects of a substance (concurrent use). Data were drawn from a nationally-representative survey of adult Americans who “regularly” or “occasionally” played video games and had played for at least one hour in the past seven days (n = 3,380). Only recent concurrent users’ data were included in analyses (n = 1,196). Independent variables included demographics, substance use frequency and problems, game genre of concurrent use (identified by looking titles up in an industry database), and general game playing variables including problem video game play (PVP), consumer involvement, enjoyment, duration, and frequency of play. Exploratory factor analysis identified the following dimensions underlying patterns of and motivations for concurrent use: pass time or regulate negative emotion, enhance an already enjoyable or positive experience, and use of video games and substances to remediate each other’s undesirable effects. Multivariate regression analyses indicated PVP and hours/day of video game play were associated with most patterns/motivations, as were caffeine, tobacco, alcohol, marijuana, and painkiller use problems. This suggests that concurrent use with some regular situational pattern or effect-seeking motivation is part of the addictive process underlying both PVP and substance dependence. Various demographic, game playing, game genre of concurrent use, and substance use variables were associated with specific motivations/patterns, indicating that all are important in understanding concurrent use.

Objectives. We examined the relationship between substance dependence and residential stability in homeless adults with current mental disorders 12 months after randomization to Housing First programs or treatment as usual (no housing or support through the study). Methods. The Vancouver At Home study in Canada included 2 randomized controlled trials of Housing First interventions. Eligible participants met the criteria for homelessness or precarious housing, as well as a current mental disorder. Residential stability was defined as the number of days in stable residences 12 months after randomization. We used negative binomial regression modeling to examine the independent association between residential stability and substance dependence. Results. We recruited 497 participants, and 58% (n = 288) met the criteria for substance dependence. We found no significant association between substance dependence and residential stability (adjusted incidence rate ratio = 0.97; 95% confidence interval = 0.69, 1.35) after adjusting for housing intervention, employment, sociodemographics, chronic health conditions, mental disorder severity, psychiatric symptoms, and lifetime duration of homelessness. Conclusions. People with mental disorders might achieve similar levels of housing stability from Housing First regardless of whether they experience concurrent substance dependence. PMID:24148035

Cannabis is the most widely used illicit substance in the United States with especially high prevalence of use among those with psychiatric disorders. Few studies have examined the relationship between concurrent cannabis use and treatment outcome among patients receiving treatment for comorbid substance abuse and psychiatric disorders. This study investigated the effects of cannabis use on treatment retention and abstinence from cocaine among cocaine dependent patients with Attention Deficit Hyperactivity Disorder (ADHD). Cocaine dependent patients diagnosed with current ADHD (DSM-IV, N = 92) aged 25 to 51 participated in a randomized clinical trial of methylphenidate for treatment of ADHD and cocaine dependence in an outpatient setting. The majority of patients (69%) used cannabis during treatment. Results suggest that moderate/intermittent cannabis users had greater retention rates compared to abstainers and consistent users (p = .02). This study is the first to examine concurrent cannabis use in cocaine dependent patients diagnosed with ADHD.

Attentional biases toward substance-related stimuli might play a contributing role in addictive behaviors. This study investigated the selective attention to substance-related stimuli in heroin dependents receiving methadone maintenance therapy. Thirty outpatients receiving methadone maintenance treatment for heroin dependence and 38 healthy controls completed a visual probe task with concurrent eye movement monitoring. The results showed that the heroin group reacted faster to probes associated with substance-related pictures than neutral pictures, and they directed more initial fixations and maintained longer initial fixation durations toward substance-related pictures than neutral pictures. However, attentional bias was not correlated with addiction severity in the heroin group. These findings suggest that attentional bias towards substance-related cues occurs in heroin dependents, although this bias might not be associated with the severity of drug-using behavior.

To evaluate the impact of concurrent treatments for substance use disorder and nicotine-dependence for stimulant-dependent patients. A randomized, 10-week trial with follow-up at 3 and 6 months after smoking quit date conducted at 12 substance use disorder treatment programs between February 2010 and July 2012. Adults meeting DSM-IV-TR criteria for cocaine and/or methamphetamine dependence and interested in quitting smoking were randomized to treatment as usual (n = 271) or treatment as usual with smoking-cessation treatment (n = 267). All participants received treatment as usual for substance use disorder treatment. Participants assigned to treatment as usual with concurrent smoking-cessation treatment received weekly individual smoking cessation counseling and extended-release bupropion (300 mg/d) during weeks 1-10. During post-quit treatment (weeks 4-10), participants assigned to treatment as usual with smoking-cessation treatment received a nicotine inhaler and contingency management for smoking abstinence. Weekly proportion of stimulant-abstinent participants during the treatment phase, as assessed by urine drug screens and self-report, was the primary outcome. Secondary measures included other substance/nicotine use outcomes and treatment attendance. There were no significant treatment effects on stimulant-use outcomes, as measured by the primary outcome and stimulant-free days, on drug-abstinence, or on attendance. Participants assigned to treatment as usual with smoking-cessation treatment, relative to those assigned to treatment as usual, had significantly better outcomes for drug-free days at 6-month follow-up (χ(2)(1) = 4.09, P <.05), with a decrease in drug-free days from baseline of -1.3% in treatment as usual with smoking-cessation treatment and of -7.6% in treatment as usual. Participants receiving treatment as usual with smoking-cessation treatment, relative to those receiving treatment as usual, had significantly better outcomes on smoking point-prevalence abstinence (25.5% vs 2.2%; χ(2)(1) = 44.69, P < .001; OR =18.2). These results suggest that providing smoking-cessation treatment to illicit stimulant-dependent patients in outpatient substance use disorder treatment will not worsen, and may enhance, abstinence from nonnicotine substance use.

Glucocorticoid activity is disrupted in substance users including khat chewers who also use tobacco. Anger, dysphoria, and anxiety can mediate this relationship. The aim of this study was to contrast emotion dysregulation and substance use variables as predictors of post-stress cortisol output. Comparable numbers of males (n = 90) and females (n = 85) including controls, khat only, and concurrent khat and tobacco users participated in a stress study. Depressive affect, anxiety, anger, substance use patterns, and saliva samples were collected following a standardized laboratory stress manipulation. Regression analysis showed that high depression and low anxiety was associated with high post-stress cortisol, but only in co-users of tobacco and khat. Males, but not females, showed a significant association between co-use of khat and tobacco and cortisol, which appears to be mediated by frequency of use. The link between anxiety and post-stress cortisol in the co-users remained significant after controlling for nicotine dependence and substance use frequency. Anxiety predicted the neuroendocrine consequences of concurrent use of tobacco and khat above and beyond sex, nicotine dependence, anger, and substance use frequency. Sex differences, however, are related to differences in nicotine dependence. Copyright © 2018. Published by Elsevier Ltd.

Mississippi has among the highest prevalence of sexually transmitted infections (STIs) in the United States. Understanding sexual networks can provide insight into risk factors for transmission and guide prevention interventions. Participants included 1437 primarily African American (95%) adults presenting for care at an STI clinic in Jackson, Mississippi. Latent class analysis identified underlying population subgroups with unique patterns of response on a comprehensive set of 14 sexual partner variables, such as living with or having a child with a partner, partner dependence and trust, 1-time sexual encounters, multiple main partners, substance use, sexual concurrency, and incarceration. Classes were compared on participant age, sex, sexual orientation, public assistance, lifetime partners, relationship status, and self-reported past-year STI. Three classes emerged. Class 1 (n = 746) participants were less dependent on partners and less likely to live with or have a child with a partner. Class 2 participants (n = 427) endorsed multiple STI risk factors, including partner incarceration, 6 or more lifetime partners, sexual concurrency, 1-time sexual encounters, and substance use at last sex. Class 3 participants (n = 226) were more likely to be in dependent, committed relationships with children. Class 2 had a higher proportion of self-report past-year STIs (36.7%) compared with classes 1 (26.6%) and 3 (26.1%). Certain partner factors such as incarceration, substance use, and concurrency may contribute to increased STI risk. Partner factors may be useful proxies for STI risks and could be useful questions to include in screening questionnaires in clinical settings.

Objective Measures of substance dependence severity that are both clinically efficient and sensitive to change can facilitate assessment of clinical innovation necessary for improving current evidence-based practices. The Leeds Dependence Questionnaire (LDQ) is a 10-item, continuous, self-report measure of dependence that is not specific to any particular substance and has shown promise in preliminary psychometric research. The present study investigates its psychometric properties in a large clinical sample of young adults. Method Emerging adults (N = 300) were enrolled in a naturalistic treatment process and outcome study of residential substance dependence treatment (mean age 20.4 [1.6], range 18–25; 27% female; 95% White). Dependence severity by demographic and diagnostic groupings, factor structure and internal consistency, and criterion- and construct-related validity were examined. Results Dependence severity in this cohort of youth overall was high (M = 18.65 [8.65]). LDQ scores were highest among opiate and stimulant users, and there was a trend for higher scores among women compared to men (t = 1.869, p = .063). Factor analysis using a robust alpha factoring extraction revealed a single factor accounting for 63% of the variance in reported dependence severity. The internal consistency was also very high (alpha = .93). Concurrent and convergent validity with dependence criteria, substance use frequency, and general symptom severity, respectively, were also acceptable. Conclusions The LDQ shows considerable promise as a brief, psychometrically sound, measure of substance dependence useful across a variety of substances, that has clinical and research utility. This study supports its use among emerging adults. PMID:20004062

This study assessed lifetime and current prevalence rates of mental disorders and concurrent mental and substance use disorders in a sample of homeless women. Current suicide risk and recent health service utilization were also examined in order to understand the complex mental health issues of this population and to inform the development of new treatment strategies that better meet their specific needs. A cross-sectional survey of 196 adult homeless women in three different Canadian cities was done. Participants were assessed using DSM-IV-based structured clinical interviews. Current diagnoses were compared to available mental health prevalence rates in the Canadian female general population. Current prevalence rates were 63% for any mental disorder, excluding substance use disorders; 17% for depressive episode; 10% for manic episode; 7% for psychotic disorder; 39% for anxiety disorders, 28% for posttraumatic stress disorder; and 19% for obsessive-compulsive disorder; 58% had concurrent substance dependence and mental disorders. Lifetime prevalence rates were notably higher. Current moderate or high suicide risk was found in 22% of the women. Participants used a variety of health services, especially emergency rooms, general practitioners, and walk-in clinics. Prevalence rates of mental disorders among homeless participants were substantially higher than among women from the general Canadian population. The percentage of participants with moderate or high suicide risk and concurrent disorders indicates a high severity of mental health symptomatology. Treatment and housing programs need to be accompanied by multidisciplinary, specialized interventions that account for high rates of complex mental health conditions.

Researchers have consistently linked commercial sexual exploitation (CSE) of youth and involvement in prostitution with substance dependency and delinquency. Yet, important questions remain regarding the directionality and mechanisms driving this association. Utilizing a sample of 114 CSE/prostituted youth participating in the Pathways to Desistance study-a longitudinal investigation of the transition from adolescence to adulthood among serious adolescent offenders-the current study examined key criminal career parameters of CSE/prostitution including age of onset and rate of recurrence. Additionally, structural equation modeling (SEM) was used to explore concurrent associations and causal links between CSE/prostitution and drug involvement. Findings show a general sequential pattern of the ages of onset with substance use and selling drugs occurring prior to CSE/prostitution, evidence that a small group with chronic CSE/prostitution account for the majority of CSE/prostitution occurrences, and high rates of repeated CSE/prostitution. SEM results suggest CSE/prostituted youth persist in drug involvement from year to year but infrequently experience perpetuation of CSE/prostitution from year to year. Concurrent associations between CSE/prostitution and drug involvement were found across the length of the study. Additionally, drug involvement at one year was linked to CSE/prostitution during the subsequent year during early years of the study. © The Author(s) 2014.

The current study examined the preliminary efficacy of dialectical behaviour therapy (DBT) adapted for concurrent eating disorders (EDs) and substance use disorders (SUDs). A matched randomized controlled trial was carried out with 25 female outpatients diagnosed with concurrent ED and SUD. Participants randomized to the intervention condition received DBT, whereas those randomized to the control condition received treatment as usual (TAU), both for a period of 1 year. A series of measures related to disordered eating, substance use and depression were administered to the participants at the beginning of treatment and at 3, 6, 9 and 12 months into treatment, followed by 3-month and 6-month follow-up assessments. Participants randomized to the DBT condition evidenced a superior retention rate relative to their counterparts in the TAU condition at various study time points, including post-treatment (80% versus 20%) and follow-up (60% versus 20%). Due to the unexpected elevated dropout rates and the worsening of ED-SUD symptomatology in the TAU condition, recruitment efforts were terminated early. Results from the DBT condition revealed that the intervention had a significant positive effect on behavioural and attitudinal features of disordered eating, substance use severity and use, negative mood regulation and depressive symptoms. Finally, increases in participants' perceived ability to regulate and cope with negative emotional states were significantly associated with decreases in emotional eating and increases in levels of confidence in ability to resist urges for substance use. Results suggest that the adapted DBT might hold promise for treating individuals with concurrent ED and SUD. The current study is the first study to report positive effects of DBT on individuals with concurrent eating and substance use disorders. Although the results require replication and extension, they suggest that the DBT may be promising for this population. The results suggest that clinicians treating individuals with concurrent eating and substance use problems should be particularly cautious of poor treatment retention and treatment complications. The results bear upon the highly salient and important issue of whether individuals with concurrent substance use need to be excluded from research studies and treatment programmes.

Substance use disorders are major contributors to excess mortality among individuals with attention deficit hyperactivity disorder (ADHD), yet associations between pharmacological ADHD treatment and substance-related problems remain unclear. This study investigated concurrent and long-term associations between ADHD medication treatment and substance-related events. The authors analyzed 2005-2014 commercial health care claims from 2,993,887 (47.2% female) adolescent and adult ADHD patients. Within-individual analyses compared the risk of substance-related events (i.e., emergency department visits related to substance use disorders) during months in which patients received prescribed stimulant medication or atomoxetine relative to the risk during months in which they did not. In adjusted within-individual comparisons, relative to periods in which patients did not receive ADHD medication, male patients had 35% lower odds of concurrent substance-related events when receiving medication (odds ratio=0.65, 95% CI=0.64-0.67), and female patients had 31% lower odds of concurrent substance-related events (odds ratio=0.69, 95% CI=0.67-0.71). Moreover, male patients had 19% lower odds of substance-related events 2 years after medication periods (odds ratio=0.81, 95% CI=0.78-0.85), and female patients had 14% lower odds of substance-related events 2 years after medication periods (odds ratio=0.86, 95% CI= 0.82-0.91). Sensitivity analyses supported most findings but were less consistent for long-term associations among women. These results provide evidence that receiving ADHD medication is unlikely to be associated with greater risk of substance-related problems in adolescence or adulthood. Rather, medication was associated with lower concurrent risk of substance-related events and, at least among men, lower long-term risk of future substance-related events.

Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management, self control, stimulus control, communication and child management skills training exercises, and financial management components. Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental control and follow-up data collection) of this case example are discussed in light of these results. PMID:23226920

This study tested the hypothesis that playing video games while using or feeling the effects of a substance--referred to herein as "concurrent use"-is related to substance use problems after controlling for substance use frequency, video gaming as an enthusiastic hobby, and demographic factors. Data were drawn from a nationally representative online survey of adult video gamers conducted by Knowledge Networks, valid n = 2,885. Problem video game playing behavior was operationalized using Tejeiro Salguero and Bersabé Morán's 2002 problem video game play (PVP) measure, and measures for substance use problems were taken from the National Survey of Drug Use and Health (NSDUH). Separate structural equation modeling analyses were conducted for users of caffeine, tobacco, alcohol, and marijuana. In all four models, concurrent use was directly associated with substance use problems, but not with PVP. Video gaming as an enthusiastic hobby was associated with substance use problems via two indirect paths: through PVP for all substances, and through concurrent use for caffeine, tobacco, and alcohol only. Results illustrate the potential for "drug interaction" between self-reinforcing behaviors and addictive substances, with implications for the development of problem use.

The psychostimulant drugs cocaine and methamphetamine are potent indirect dopamine receptor agonists which act through similar but not identical mechanisms. Studies in humans have observed that a large proportion of those who chronically use these drugs experience psychotic symptoms. However, direct comparisons of psychotic symptom severity between cocaine and methamphetamine users are lacking. The goal of the present study was to directly compare severity of psychotic symptoms between cocaine- and methamphetamine-dependent individuals. Additionally, we sought to determine how concurrent cocaine + methamphetamine dependence would influence psychotic symptoms. We recruited 153 polysubstance-using subjects meeting DSM-IV-TR criteria for cocaine dependence, 38 with methamphetamine dependence, and 32 with cocaine + methamphetamine dependence. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS) and analyzed using a five-factor model. All participants were also assessed for physical and mental illnesses as well as recent substance use. Most subjects completed a comprehensive neurocognitive battery. While all three groups exhibited high total PANSS scores, the positive symptom subscale was significantly higher in the methamphetamine-dependent (17.03 ± 6.3) than the cocaine-dependent group (13.51 ± 4.12) and non-significantly higher (p = 0.08) than the cocaine + methamphetamine group (14.44 ± 5.50). Groups also differed on demographic variables, viral infection, and other indices of substance use, which were unlikely to account for the difference in positive symptoms. There were only modest differences between groups in neurocognitive function. Methamphetamine dependence was associated with more severe positive symptoms of psychosis than cocaine dependence. Concurrent cocaine + methamphetamine dependence did not increase psychosis severity.

Young women who regularly attend nightclubs are at risk for numerous health and social consequences, including mental distress, sexual and physical victimization and substance dependence. This paper uses a biopsychosocial framework to examine co-occurring mental health problems, victimization, substance dependence, sexual risk and physical pain among a sample of young women who use drugs (N = 222) in Miami's club scene. The majority of women were under 24 years old, Hispanic, and identified as heterosexual. Almost all the women reported past 90-day use of alcohol, ecstasy/MDMA, marijuana, cocaine and prescription opioids and benzodiazepines; 32% of women reported being in a monogamous relationship while 41.9% reported having three or more sexual partners in the past 90 days; 65.3% met DSM-IV criteria for substance dependence; 60.4% met DSM-IV criteria for serious mental illness (SMI) and 59.9% were victimized as minors. Women who had SMI had higher odds of substance dependence, concurrent physical pain, three or more sexual partners in the past 90 days, childhood victimization and severe abuse-related trauma. The high levels of interconnected mental health, victimization, trauma, physical pain, substance dependence and sexual risk factors observed are underreported in the literature, as young women club scene participants appear to be more similar to other marginalized drug-involved populations than previously considered. While further research is needed, it appears these young women are in great need of outreach for primary health, mental health, HIV prevention, increased social support and substance abuse treatment services.

Smoking is highly prevalent among individuals with drug and alcohol disorders. Concurrent tobacco dependence treatment during substance use disorder (SUD) treatment is supported, yet the association between SUD treatment outcomes and smoking status has been understudied in minorities, including Latinos. Participants were 322 Spanish-speaking Latinos enrolled in a SUD treatment study in 5 U.S. cities. Logistic regression examined associations between baseline smoking status and treatment outcomes for nontobacco substance use at follow-up. Covariates included age, gender, level of education, marital status, treatment group, and mandated treatment status. Results indicated smokers had a reduced likelihood of abstinence for all nontobacco substances (p = .001) and their primary drug of use (p = .007). Findings contribute to the growing literature indicating a possible beneficial effect of smoking cessation services on SUD treatment, specifically among Latinos. Further research is needed to identify ideal smoking cessation treatments for Latinos. © 2016 Wiley Periodicals, Inc.

Substance dependence is one of the main factors contributing to morbidity and mortality worldwide. Gambling disorder has recently been included as an addictive disorder in DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) and is associated with substantial psychiatric comorbidity and respective disability. Nevertheless, the vast majority of those suffering from these disorders do not receive treatment. In Israel, prevalence of substance dependence has traditionally been estimated to be lower than those in high-income countries, though prevalence estimates from the recent decade are lacking. Moreover, characteristics of individuals seeking treatment for substance dependence and gambling disorder have not been published. In this study, the authors analyzed data from the Israel National Addiction Registry, a computerized database that includes sociodemographic characteristics of all individuals treated in specialized public facilities for substance dependence and gambling disorders in the years 2003-2012. The prevalence of treatment utilization for drug and alcohol dependence and gambling disorders were 0.2%, 0.1%, and 0.01%, respectively. These rates generally remained stable throughout the last decade. Individuals seeking treatment for alcohol dependence were in the lower socioeconomic status (SES) cluster, whereas those seeking treatment for drug dependence were in the midrange SES clusters, findings that are generally in concurrence with characteristics of treatment seekers in high-income countries. Prevalence estimates based on reports indicating that approximately 10% of individuals with substance dependence seek treatment suggest rates of alcohol dependence in Israel that are substantially higher those previously published, though still lower than most high-income countries. Nationwide epidemiologic studies exploring current rates of substance dependence and gambling disorder in Israel are urgently needed, and treatment options should be planned and funded accordingly. Potential reasons for these apparent low rates of treatment utilization for these disorders in Israel should be explored in order to improve services provided for this population.
The Diagnostic Dilemma of Pathological Appearance and Performance Enhancing Drug Use

Appearance and performance enhancing drug (APED) use includes the use of a range of pharmacologically distinct substances and concurrent investment in outward appearance or achievement, dietary control, and frequent exercise. A number of existing reviews and conceptual papers have defined pathological forms of APED use within the APED class of anabolic-androgenic steroids (AASs) and using the framework of AAS dependence. We review published data on APED use including human studies of AAS users and identified three defining phenomenological features associated with increased health risk and pathology. These features included (1) polypharmacy or the concurrent use of several pharmacologically distinct substances used to change outward appearance or increase likelihood of personal achievement; (2) significant body image disturbance; (3) rigid practices and preoccupations with diet and exercise. Investigations into the latent structure of APED use suggest these features cluster together in a homogenous group of APED users who have the highest health risk and most psychopathology. These features are discussed in the context of AAS dependence and problems with defining classic tolerance-withdrawal symptoms among APED users. Suggestions for a resolution and outline for future research needed to determine the best system for identifying and diagnosing pathological APED use are discussed. PMID:21115306

Substance dependence and antisocial psychopathology, such as a history of childhood conduct disorder (HCCD), are associated with impulsive or disadvantageous decision making and reduced working memory capacity (WMC). Reducing WMC via a working memory load increases disadvantageous decision making in healthy adults, but no previous studies have examined this effect in young adults with substance dependence and HCCD. Young adults with substance dependence (SubDep; n=158, 71 female), substance dependence and HCCD (SubDep+HCCD; n=72, 24 female), and control participants (n=152, 84 female) completed a test of decision making (the Iowa Gambling Task; IGT) with or without a concurrent working memory load intended to tax WMC. Outcomes were (i) net advantageous decisions on the IGT, and (ii) preferences for infrequent- versus frequent-punishment decks. SubDep+HCCD men made fewer advantageous decisions on the IGT than control men without a load, but there were no group differences among women in that condition. Load was associated with fewer advantageous decisions for SubDep+HCCD women and control men, but not for men or women in the other groups. Participants showed greater preference for infrequent-punishment, advantageous decks under load as well. There are gender differences in the effects of substance dependence, HCCD, and working memory load on decision making on the IGT. Decision making by control men and SubDep+HCCD women suffered the most under load. Load increases preferences for less-frequent punishments, similar to a delay discounting effect. Future research should clarify the cognitive and neural mechanisms underlying these effects. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

High rates of co-occurrence between substance abuse and child neglect have been well documented and especially difficult to treat. As a first step in developing a comprehensive evidence-based treatment for use in this population, the present case examination underscores Family Behavior Therapy (FBT) in the treatment of a mother who evidenced Substance Dependence, child neglect, Post-Traumatic Stress Disorder, Bipolar I Disorder, and domestic violence. Utilizing psychometrically validated self-report inventories and objective urinalysis, treatment was found to result in the cessation of substance use, lower risk of child maltreatment, improved parenting attitudes and practices, and reduced instances of violence in the home. The importance of utilizing validity scales in the assessment of referrals from child welfare settings is discussed, and future directions are reported in light of the results. PMID:23457426

Background: Cannabis is one of the most widely used illicit drugs in India and worldwide. It is considered to have a minimal effect on physical health. Objectives: The aim of this study was to compare the laboratory profiles of treatment-seeking patients who were cannabis dependent, and drug users who concurrently use other substances, with non-users. Materials and Methods: Medical records of patients, whose urine was tested for the detection of cannabis within the last year, were considered for the study. The inclusion criteria for the study group were; co-morbid diagnosis of cannabis dependence according to DSM-IV TR criteria, positive urine drug screen for cannabis, and at least one biochemical or hematological examination report during the treatment period. The subjects who underwent all of the above mentioned tests, but who were negative for any psychoactive substance with no past or current history of substance use, were placed in the control group. Results: A total of 51 subjects fulfilled the inclusion criteria for the study group and 30 subjects were considered as controls. There was no significant difference found between the demographic profiles of the subject and control groups. The mean duration of cannabis use in the patients was 9.53 ± 8.06 years. Serum levels of; bilirubin, SGOT (serum glutamic oxaloacetic transaminase), SGPT (serum glutamic pyruvic transaminase), total protein, alkaline phosphatase, ESR, and eosinophil counts, were raised in; 13.7%, 15.6%, 33.3%, 17.6%, 37.2%, 75% and 5.8% of subjects, respectively. The relative monocyte count was lower than normal in 92% of cases. Physical complaints were reported in 98% of subjects. The two groups showed significant differences in serum alkaline phosphatase [t (79) = 6.5, P ≤ 0.01], TLC [t (79) = 2.36, P = 0.03] and hemoglobin levels [t (79) = 5.50, P ≤ 0.01]. Conclusions: Abnormal laboratory parameters were observed in patients with cannabis dependence. The study emphasizes the need for regular physical examinations and laboratory investigations for cannabis users. PMID:24971286
Nicolaus Taurellus on forms and elements.
Blank, Andreas
2014-12-01
This article examines the conception of elements in the natural philosophy of Nicolaus Taurellus (1547-1606) and explores the theological motivation that stands behind this conception. By some of his early modern readers, Taurellus may have been understood as a proponent of material atoms. By contrast, I argue that considerations concerning the substantiality of the ultimate constituents of composites led Taurellus to an immaterialist ontology, according to which elements are immaterial forms that possess active and passive potencies as well as motion and extension. In Taurellus's view, immaterialism about elements provides support for the theological doctrine of creation ex nihilo. As he argues, the ontology of immaterial forms helps to explicate a sense in which creatures are substances, not accidents of the divine substance. In particular, he maintains that immaterial forms stand in suitable relations of ontological dependence to God: creation dependence (since forms would not exist without the divine act of creation), but neither subsistence dependence (since forms continue to exist without continued divine agency) nor activity dependence (since forms are active without requiring divine concurrence).
Concurrent Use of Cannabis and Alcohol: Neuropsychiatric Effect Consequences.

2017-01-01
Concurrent use of cannabis and alcohol is frequent. According different studies, the prevalence is among 20-34% depending on different samples studied. In contrast with the wide evidence available about neuropsychiatric effects associated to the use of cannabis or alcohol separately, there are few studies of the neuropsychiatric effects of their combination. Our aim was to review the literature regarding this topic. We performed a search in MEDLINE and from 114 potentially eligible studies, 27 were selected. Most of them studied the relation between cannabis and alcohol, and with them combined to other substances of abuse, but only a few considered their concurrent effect among mental disorders (ADHD, bipolar disorder) and neuropsychological performance. More research in the neuropsychiatric effects of the concomitant use of cannabis and alcohol is needed.

Objective This study examined the impact of coping motives for cannabis and alcohol use on the relation between social anxiety/depressive symptoms and severity of substance use for alcohol, tobacco, and cannabis among treatment-seeking smokers who also use cannabis and alcohol. Methods The sample included 197 daily cigarette smokers (MAge 34.81 yrs, SD = 13.43) who reported using cannabis and alcohol. Results Hierarchical multiple regression analyses were conducted wherein separate models were constructed for each dependent variable. Among individuals with higher social anxiety, alcohol coping motives were associated with heavier drinking, and this was more pronounced among those low in depressive symptoms. Similarly, those at greater risk for nicotine dependence were anxious individuals with lower depressive symptoms who endorse coping-oriented motives for using cannabis. Further, among those with higher social anxiety, cannabis coping motives were associated with marginally greater drinking, particularly for those high in depressive symptoms. Conclusions The present findings support the perspective that among multi-substance users, the interplay between social anxiety, depressive symptoms, and coping-oriented motives for using one substance (e.g., cannabis or alcohol) may pose difficulties in refraining from other substances (e.g., tobacco). This observation highlights the importance of tailoring multi-substance treatments to specific needs of multi-users for whom single-substance interventions may be less effective. Findings also support previous work exploring the benefits of concurrently treating co-occurring substance use and lend credence to the perspective that motivation to use substances for coping reasons is of central theoretical and clinical relevance.

Adolescence is a vulnerable time for both substance use and bullying involvement; however, there is limited research on substance use among adolescent victims of bullying. This study aimed to examine concurrent and prospective associations between bullying and substance use, differentiating between passive-victims, bully-victims and 'pure' bullies. Associations between bullying involvement and substance use at baseline and 24 months post-baseline were examined in a cohort of adolescents in Australia. Bullying victims were divided into passive-victims (those who get bullied and do not bully others) and bully-victims (those who both get bullied and bully others). Perpetrators of bullying were divided into 'pure' bullies (those who bully others but do not get bullied), and bully-victims (as above). Outcomes examined were past six month use of alcohol (any drinking; risky drinking), tobacco, and cannabis. While there was no evidence of an association between bullying victimization and/or perpetration and substance use at baseline, there was evidence of an association between bullying and substance use 24 months post-baseline. Specifically, there was evidence of increased odds of risky drinking and cannabis use for the bully-victim group. Bully-victim status at age 13 was associated with substance use at age 15, controlling for concurrent bullying involvement at age 15. Bully-victims are a particularly high-risk group that could benefit from targeted substance use preventive interventions. Reducing bullying is of great importance in reducing substance use and other harms among adolescents. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The current study aimed to understand whether substance-specific parenting practices predicted the probability of child alcohol, cigarette, or marijuana use beyond known family factors like family management and parental substance use and norms. Data were drawn from the Intergenerational Project, which used an accelerated longitudinal design and included 383 families surveyed seven times between 2002 and 2011. Analyses included 224 families with children ages 10-18 years (49% female). Multilevel models tested both concurrent and lagged (predictors at time t - 1, outcomes at time t) associations between child past year use of alcohol, cigarettes, and marijuana and time-varying measures of substance-specific parenting practices, including permitting child use of alcohol or cigarettes; family rules about alcohol, cigarette, and drug use; and child involvement in family member alcohol or cigarette use (getting, opening, or pouring alcoholic drinks; getting or lighting cigarettes for family members). Demographic controls were included. Child involvement in family member substance use predicted an increased probability of child substance use both concurrently and 1 year later, even when controlling parent substance use, pro-substance norms, and family management. Family rules about substance use and parent provision of alcohol or cigarettes were not consistently related to child alcohol, cigarette, or marijuana use. Family-based preventive interventions to reduce youth substance use should continue to focus on family management and include messaging discouraging parents from allowing children to get, open, or pour drinks or get or light cigarettes for family members.

Previous research has shown that early maladaptive schemas (EMS) play an important role in substance use, depression, and anxiety. However, few studies have examined the role of EMS within the context of all three concurrently. The goal of this study was to determine the role of EMS in predicting symptoms of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) among adults in residential treatment for substance dependence. We used pre-existing patient records of adults diagnosed with a substance use disorder from a residential substance use treatment facility (N=122). The EMS domains of disconnection and rejection and impaired limits were associated with symptoms of MDD and the domain of impaired autonomy and performance was associated with symptoms of GAD, even after controlling for age, gender, years of education, alcohol use, drug use, and symptoms of MDD (when predicting GAD) and GAD (when predicting MDD). Findings suggest that EMS may play an important role in comorbid mental health problems among men and women in residential substance use treatment. Continued treatment outcome research is needed to examine whether modification of EMS results in improved mental health and substance use outcomes.

A 10-item self-report measure of social self-control was examined for its association with substance use, controlling for its associations with 12 personality disorder indices and 4 demographic variables among a sample of 1050 high-risk youth. Social self-control was found to be associated with 30-day cigarette smoking, alcohol use, marijuana use, and hard drug use, controlling for these other variables. The most consistent concurrent predictors of substance use were male gender, antisocial personality disorder, and social self-control. These results highlight the importance of social self-control as a unique concurrent predictor of substance use and suggest that social self-control skill training is relevant in substance abuse prevention programming.

Gender-based relationship power is frequently linked to women's capacity to reduce sexual risk behaviors. This study offers an exploration of predictors of relationship power, as measured by the multidimensional and theoretically grounded sexual relationship power scale, among women in outpatient substance abuse treatment. Linear models were used to test nine predictors (age, race/ethnicity, education, time in treatment, economic dependence, substance use, sexual concurrency, partner abuse, and sex role orientation) of relationship power among 513 women participating in a multi-site HIV risk reduction intervention study. Significant predictors of relationship control included having a non-abusive male partner, only one male partner, and endorsing traditional masculine (or both masculine and feminine) sex role attributes. Predictors of decision-making dominance were interrelated, with substance use × partner abuse and age × sex role orientation interactions. Results contribute to the understanding of factors which may influence relationship power and to their potential role in HIV sexual risk reduction interventions.

The new Kreek-McHugh-Schluger-Kellogg scale ('KMSK scale') is designed to quantify self-exposure to opiates, cocaine, alcohol, and/or tobacco. Each section of the KMSK scale assesses the frequency, amount, and duration of use of a particular substance during the individual's period of greatest consumption. The scale also assesses the mode of use, whether the substance use is current or past, and whether each substance is the substance of choice. The administration time is under 5 min. In an initial validation study of this scale, 100 human subjects were administered the KMSK scale concurrently with the Structured Clinical Interview for DSM-IV (SCID-I DSM-IV version). The sensitivity and specificity were very good for opiates, cocaine, and alcohol use. In addition, the correlations between KMSK scores and the number of SCID-I criteria items met were excellent for opiates and cocaine and good for alcohol use. Nicotine dependence was not assessed in this study as there is no SCID-I nicotine criteria. These preliminary results show that the KMSK scale may have both construct validity similar to that of other established self-report measures and the potential to be an effective screening instrument for the assessment of a lifetime diagnosis of alcohol, opiate, or cocaine dependence.

Alcohol misuse in Greece: a 15-year experience from a specialized outpatient service.
Pomini, V; Mellos, L; Paparrigopoulos, T; Liappas, J
2014-01-01
Alcohol use in Greece is traditionally diffused among its population. According to general population surveys, three out of four Greeks aged 12-64 referred to alcohol consumption during the last year and 10% reported at least one episode of alcohol abuse during the last month. Furthermore, the large majority of young people aged 13-18 reported lifetime use of alcohol and 14.8% of them reported more than three episodes of alcohol abuse during the last month. Apparently, cultural factors have influenced the pattern of alcohol consumption and the ensuing alcohol-related problems during the last two decades. The "Athena" Service is an outpatient therapeutic unit for the management of substance misusers and their families. It is a specialized abstinence-oriented service that does not administer substance substitutes; mental health professionals of the service work as a multidisciplinary team. Motivational approaches, individual cognitive-behavioural psychotherapy and family interventions of a systemic orientation are the principal therapeutic techniques applied. Adjunctive medication is prescribed whenever mild to moderate concomitant psychopathology is detected. Support measures such as provisional use of medication, use of antagonistic agents or brief hospitalization can be provided if deemed necessary. No strict time limits are applied regarding treatment duration and discharge from the program. During the period 1998-2013, a total of 1511 individuals with alcohol-related problems addressed the service. The changing pattern of substance misuse over the last fifteen years can be summarized as follows: (a) there is a gradually increasing number of women misusing substances; (b) there is an increasing proportion of young adults reporting multi-substance use with concurrent psychiatric disorders; (c) there is an increasing proportion of young adults regularly using/misusing substances; (d) there is a decreasing proportion of middle-aged individuals presenting with chronic alcohol misuse and dependence, with a long-ago onset and slow development of alcohol-related problems; and (e) the proportion of older age individuals presenting chronic alcohol misuse and dependence with concurrent severe neurological impairments is increasing. Also, detailed information on a sample of 133 individuals who addressed the service for alcohol-related problems during 2012 is given and further discussed. Finally, the need for close monitoring of dangerous alcohol consumption and changing patterns of misuse in times of socio-economic crisis, alongside with an increasing need to provide treatment, is highlighted.
Concurrent substance-related disorders and mental illness: the North American experience

Ingredients of the evolving North American experience in addressing the management of patients with concurrent substance-related disorders and mental illness are presented. This experience as well as select data from Europe and Australia indicate a growing empirically-based consensus to provide an integrated approach to the care of these patients. It also highlights the necessity to conduct local surveys of needs and resources and adapt the published clinical experience to the local system of care, resources and culture. PMID:16633492

Clarifying the Relationship between Impulsive Delay Discounting and Nicotine Dependence
Amlung, Michael; MacKillop, James
2014-01-01
Impulsive delayed reward discounting (DRD) has been linked to nicotine dependence, but with some inconsistency. This may be related to the considerable variability in the literature with regard to the DRD assessments used, particularly in the case of reward magnitudes assessed. In addition, previous studies have often not considered concurrent substance use when examining the relationship between DRD and nicotine dependence. The current study sought to further clarify the relationship between DRD and nicotine dependence by characterizing DRD across diverse reward magnitudes and incorporating other substance use. Daily smokers (N = 933) were assessed for DRD preferences across nine reward magnitudes (delayed reward range: $2.50–$850), comorbid substance use, and relevant demographic variables (age, education, income). A significant large effect size magnitude effect was found for DRD, reflecting steeper discounting for smaller delayed rewards, but significant correlations across magnitudes also suggested similar relative levels of discounting. Principal components analysis (PCA) was used to generate a single latent index of discounting across all magnitudes that accounted for 67% of the total variance. In both correlation and regression analyses, steeper composite DRD was significantly associated with nicotine dependence severity. This relationship remained statistically significant after incorporating demographic variables and alcohol and illicit drug use. These findings provide evidence of a specific link between impulsive DRD and nicotine dependence, and reveal that this association is robust across a broad range of monetary rewards. The study also demonstrates the utility of using PCA to generate latent indices of delay discounting across multiple magnitudes of delayed reward. PMID:24841186

There are many known risk factors associated with youth substance use. Nonetheless, the impact of life satisfaction (LS) on the use of alcohol, tobacco and marijuana by adolescents still remains largely unknown. The present analysis utilized data from the Health Behavior in School-Aged Children 2009-10 US study. Multilevel logistic regression models were used to assess the relationship between LS and individual substance use. Multilevel multinomial regression models examined the relationship with total number of substances used. After controlling for numerous variables associated with substance use, individuals reporting low LS were significantly more likely to ever use tobacco (OR = 1.34, 95% CI = [1.01, 1.78]), alcohol (OR = 1.45, 95% CI = [1.10, 1.92]) and marijuana (OR = 1.98, 95% CI = [1.39, 2.82]). Additionally, students with low LS were significantly more likely to use two substances (OR = 1.90, 95% CI = [1.15, 3.14]) and three substances concurrently (OR = 2.00, 95% CI = [1.27, 3.16]). The present study identified strong associations between LS and individual, as well as concurrent, substance use among adolescents. Interventions aiming to reduce adolescent substance use may benefit from incorporating components to improve LS.
Insights from Preclinical Choice Models on Treating Drug Addiction
Banks, Matthew L.; Negus, S. Stevens
2016-01-01
Substance-use disorders are a global public health problem that arises from behavioral misallocation between drug use and more adaptive behaviors maintained by nondrug alternatives (e.g., food or money). Preclinical drug self-administration procedures that incorporate a concurrently available nondrug reinforcer (e.g., food) provide translationally relevant and distinct dependent measures of behavioral allocation (i.e., to assess the relative reinforcing efficacy of the drug) and behavioral rate (i.e., to assess motor competence). In particular, preclinical drug versus food ‘choice’ procedures have produced increasingly concordant results with both human laboratory drug self-administration studies and double-blind placebo-controlled clinical trials. Accordingly, here we provide a heuristic framework of substance-use disorders based on a behavioral-centric perspective and recent insights from these preclinical choice procedures. PMID:27916279

Tobacco and cannabis are highly co-morbid in the general population and in patients with schizophrenia. Given the putative causal mechanisms facilitating co-use, it is important to determine how cannabis cessation may influence concurrent tobacco use. Using a 28-day cannabis abstinence paradigm, we prospectively examined changes in tobacco consumption in patients with schizophrenia and controls with cannabis dependence and daily cigarette use. Cannabis dependent patients with schizophrenia (n = 19) and controls (n = 20) completed the study with abstinence rates of 42% and 55%, respectively. Participants completed measures of substance use, withdrawal, and clinical symptoms weekly. Urine samples were collected twice weekly to biochemically verify abstinence. Patients reported a greater increase in cigarettes smoked per day (CPD) on Day 7 relative to baseline (2.97 cigarette increase for abstinent subgroup, p < .01) compared to controls (.06 cigarette increase for abstinent subgroup, p = .95). Initially, greater reductions in cannabis use related to greater increases in CPD relative to baseline in the patient subsample (simple slope = -2.31, p = .05), but by Day 28, CPD returned to baseline levels independent of cannabis use. CPD changes were unrelated to cannabis withdrawal. Results were similar for changes in caffeine consumption, but not for alcohol. Findings suggest transient tobacco substitution for cannabis in patients with schizophrenia. This provides further support for a strong association between cannabis and tobacco in schizophrenia. Future studies should focus on targeting underlying mechanisms that promote co-use to better address potential changes in concurrent substance use during treatment interventions.

This study compares cigarette smoking knowledge, attitudes, and practices (S-KAP) of opioid- and other substance-dependent patients and their multidisciplinary staff at an outpatient perinatal substance abuse treatment center. Consenting patients (n = 95) and staff (n = 41) concurrently completed a modified form of the S-KAP survey instrument. Ninety-five percent of patients reported currently smoking, and half endorsed wanting "to quit smoking now." This patient desire to quit smoking was significantly underrated by staff compared to the patients themselves (p = .028). Both patients and staff demonstrated suboptimal knowledge of smoking health risks, but 73% of patients reported trying to quit with past pregnancies to avoid harm to the fetus/baby. Although results show that patients could benefit from smoking cessation strategies centered on smoking's fetal/neonatal health risks, organizational interventions that focus on changing staff attitudes about patient desire to quit smoking may first need to be implemented.

Research on interventions to positively impact health and housing status of people who are homeless has received substantially increased attention over the past 5 years. This rapid review examines recent evidence regarding interventions that have been shown to improve the health of homeless people, with particular focus on the effect of these interventions on housing status. A total of 1,546 articles were identified by a structured search of five electronic databases, a hand search of grey literature and relevant journals, and contact with experts. Two reviewers independently screened the first 10% of titles and abstracts for relevance. Inter-rater reliability was high and as a result only one reviewer screened the remaining titles and abstracts. Articles were included if they were published between January 2004 and December 2009 and examined the effectiveness of an intervention to improve the health or healthcare utilization of people who were homeless, marginally housed, or at risk of homelessness. Two reviewers independently scored all relevant articles for quality. Eighty-four relevant studies were identified; none were of strong quality while ten were rated of moderate quality. For homeless people with mental illness, provision of housing upon hospital discharge was effective in improving sustained housing. For homeless people with substance abuse issues or concurrent disorders, provision of housing was associated with decreased substance use, relapses from periods of substance abstinence, and health services utilization, and increased housing tenure. Abstinent dependent housing was more effective in supporting housing status, substance abstinence, and improved psychiatric outcomes than non-abstinence dependent housing or no housing. Provision of housing also improved health outcomes among homeless populations with HIV. Health promotion programs can decrease risk behaviours among homeless populations. These studies provide important new evidence regarding interventions to improve health, housing status, and access to healthcare for homeless populations. The additional studies included in this current review provide further support for earlier evidence which found that coordinated treatment programs for homeless persons with concurrent mental illness and substance misuse issues usually result in better health and access to healthcare than usual care. This review also provides a synthesis of existing evidence regarding interventions that specifically support homeless populations with HIV.

Background Research on interventions to positively impact health and housing status of people who are homeless has received substantially increased attention over the past 5 years. This rapid review examines recent evidence regarding interventions that have been shown to improve the health of homeless people, with particular focus on the effect of these interventions on housing status. Methods A total of 1,546 articles were identified by a structured search of five electronic databases, a hand search of grey literature and relevant journals, and contact with experts. Two reviewers independently screened the first 10% of titles and abstracts for relevance. Inter-rater reliability was high and as a result only one reviewer screened the remaining titles and abstracts. Articles were included if they were published between January 2004 and December 2009 and examined the effectiveness of an intervention to improve the health or healthcare utilization of people who were homeless, marginally housed, or at risk of homelessness. Two reviewers independently scored all relevant articles for quality. Results Eighty-four relevant studies were identified; none were of strong quality while ten were rated of moderate quality. For homeless people with mental illness, provision of housing upon hospital discharge was effective in improving sustained housing. For homeless people with substance abuse issues or concurrent disorders, provision of housing was associated with decreased substance use, relapses from periods of substance abstinence, and health services utilization, and increased housing tenure. Abstinent dependent housing was more effective in supporting housing status, substance abstinence, and improved psychiatric outcomes than non-abstinence dependent housing or no housing.

Background Many with alcohol and other drug dependence have concurrent marijuana use, yet it is not clear how to address it during addiction treatment. This is partially due to the lack of clarity about whether marijuana use impacts one’s ability to achieve abstinence from the target of addiction treatment. We examined the association between marijuana use and abstinence from other substances among individuals with substance dependence. Methods A secondary analysis of the Addiction Health Evaluation And Disease management study, a randomized trial testing the effectiveness of chronic disease management. Individuals met criteria for drug or alcohol dependence and reported recent drug (i.e. opioid or stimulant) or heavy alcohol use. Recruitment occurred at an inpatient detoxification unit, and all participants were referred to primary medical care. The association between marijuana use and later abstinence from drug and heavy alcohol use was assessed using longitudinal multivariable models. Results Of 563 study participants, 98% completed at least one follow-up assessment and 535 (95%) had at least one pair of consecutive assessments and were included. In adjusted analyses, marijuana use was associated with a 27% reduction in the odds of abstinence from drug and heavy alcohol use (adjusted odds ratio 0.73 [95% CI, 0.56–0.97], P=0.03). Conclusions Marijuana use among individuals with alcohol or other drug dependence is associated with a lower odds of achieving abstinence from drug and heavy alcohol use. These findings add evidence that suggests concomitant marijuana use among patients with addiction to other drugs merits attention from clinicians. PMID:24986785

We conducted a comparative analysis of gender differences in patients with primary psychotic disorders with concurrent substance use and in those with substance-induced psychoses. A total of 385 individuals admitted to psychiatric emergency departments with early-onset psychosis and recent substance use were interviewed at baseline and at six-month intervals for two years. Using a standardized research diagnostic assessment instrument, we classified patients at baseline into primary and substance-induced psychosis groups and analyzed the effects of gender on demographic, family, and clinical characteristics at baseline, the interaction of gender and diagnosis, and gender main effects on illness course, adjustment, and service use over the two-year follow-up period. Women had better premorbid adjustment, less misattribution of symptoms, and a later age at onset of regular drug use compared to men. Women, however, showed greater depression and histories of abuse compared to men. Men had greater arrest histories. No interactions between gender and diagnosis were significant. Both genders in the primary and substance-induced psychosis groups showed clinical and functional improvement over the follow-up period despite the overall minimal use of mental health and substance abuse treatment services. Women and men with psychosis and substance use differ on several dimensions. Our findings suggest the need for gender-specific treatment programming across both diagnostic groups.

Substance use and violence co-occur among adolescents. However, the extant literature focuses on the substance use behaviors of perpetrators of violence and not on victims. This study identifies patterns of school victimization and substance use and how they co-occur. The California Healthy Kids Survey was used to identify latent classes/clusters of school victimization patterns and lifetime and frequency of recent (past month) alcohol, tobacco, and marijuana use (N =419,698). Demographic characteristics (age, gender, and race/ethnicity) were included as predictors of latent class membership. Analyses revealed four latent classes of school victimization: low victimization (44.4 %), moderate victimization (22.3 %), verbal/relational victimization (20.8 %), and high victimization (with physical threats; 12.5 %). There were also four classes of substance use: non-users (58.5 %), alcohol experimenters (some recent alcohol use; 25.8 %), mild poly-substance users (lifetime use of all substances with few days of recent use; 9.1 %), and frequent poly-substance users (used all substances several times in the past month; 6.5 %). Those in the high victimization class were twice as likely to be frequent poly-substance users, and mild poly-substance use was most salient for those in the verbal victimization class. Few studies have explored latent patterns of substance use and violence victimization concurrently. The findings indicate substantial heterogeneity in victimization and substance use among youth in California schools with implications for targeted and tailored interventions. Understanding how certain types of victimization are associated with particular patterns of substance use will provide schools with opportunities to screen for concurrent behavioral health problems among youth.

Insights from Preclinical Choice Models on Treating Drug Addiction.
Banks, Matthew L; Negus, S Stevens
2017-02-01
Substance-use disorders are a global public health problem that arises from behavioral misallocation between drug use and more adaptive behaviors maintained by nondrug alternatives (e.g., food or money). Preclinical drug self-administration procedures that incorporate a concurrently available nondrug reinforcer (e.g., food) provide translationally relevant and distinct dependent measures of behavioral allocation (i.e., to assess the relative reinforcing efficacy of the drug) and behavioral rate (i.e., to assess motor competence). In particular, preclinical drug versus food 'choice' procedures have produced increasingly concordant results with both human laboratory drug self-administration studies and double-blind placebo-controlled clinical trials. Accordingly, here we provide a heuristic framework of substance-use disorders based on a behavioral-centric perspective and recent insights from these preclinical choice procedures.

Individuals in recovery from alcohol use disorders (AUDs) frequently continue to smoke cigarettes. The purpose of this study was to examine the relationship between cigarette smoking status and risk of AUD relapse in adults with remitted AUDs among adults in the United States. Data were drawn from Wave 1 (2001 to 2002) and Wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses included the subsample of respondents who completed both waves of data collection reported a history of alcohol abuse and/or dependence prior to Wave 1 (N = 9,134). Relationships between Wave 1 cigarette smoking status (nonsmoker, daily cigarette smoker, and nondaily cigarette smoker) and Wave 2 alcohol use, abuse, and dependence were examined using logistic regression analyses. Analyses were adjusted for Wave 1 demographics; mood, anxiety, and substance use disorders; nicotine dependence; and AUD severity. Both daily and nondaily cigarette smoking at Wave 1 were significantly associated with a lower likelihood of alcohol use and a greater likelihood of alcohol abuse and dependence at Wave 2 compared to Wave 1 nonsmoking. These relationships remained significant after adjusting for demographics, psychiatric disorders, substance use disorders, AUD severity, and nicotine dependence. Among adults with remitted AUDs, daily and nondaily use of cigarettes was associated with significantly decreased likelihood of alcohol use and increased likelihood of alcohol abuse and alcohol dependence 3 years later. Concurrent treatment of cigarette smoking when treating AUDs may help improve long-term alcohol outcomes and reduce the negative consequences of both substances.

Objectives The causes of disability among chronic methamphetamine (MA) users are multifactorial. The current study examined the additive adverse impact of human immunodeficiency virus (HIV) infection, a common comorbidity in MA users, on functional dependence. Methods A large cohort of participants (N=798) stratified by lifetime MA dependence diagnoses (i.e., MA+ or MA−) and HIV serostatus (i.e., HIV+ or HIV−) underwent comprehensive baseline neuromedical, neuropsychiatric, and functional research evaluations, including assessment of neurocognitive symptoms in daily life, instrumental and basic activities of daily living, and employment status. Results Independent, additive effects of MA and HIV were observed across all measures of functional dependence, independent of other demographic, psychiatric, and substance use factors. The prevalence of global functional dependence increased in the expected stepwise fashion across the cohort, with the lowest rates in the MA−/HIV− group (29%) and the highest rates in the MA+/HIV+ sample (69%). The impact of HIV on MA-associated functional dependence was moderated by nadir CD4 count, such that MA use was associated with greater disability among those HIV-infected persons with higher, but not lower nadir CD4. Within the MA+/HIV+ cohort, functional dependence was reliably associated with neurocognitive impairment, lower cognitive reserve, polysubstance use, and major depressive disorder. Conclusions HIV infection confers an increased concurrent risk of MA-associated disability, particularly among HIV-infected persons without histories of immune compromise. Directed referrals, earlier HIV treatment, and compensatory strategies aimed at counteracting the effects of low cognitive reserve, neurocognitive impairment, and psychiatric comorbidities on functional dependence in MA+/HIV+ individuals may be warranted.

Disability among long-term methamphetamine (MA) users is multifactorial. This study examined the additive adverse impact of human immunodeficiency virus (HIV) infection, a common comorbidity in MA users, on functional dependence. A large cohort of participants (N = 798) stratified by lifetime MA-dependence diagnoses (ie, MA+ or MA-) and HIV serostatus (ie, HIV+ or HIV-) underwent comprehensive baseline neuromedical, neuropsychiatric, and functional research evaluations, including assessment of neurocognitive symptoms in daily life, instrumental and basic activities of daily living, and employment status.

Varenicline, a nicotinic partial agonist, selectively reduces ethanol (EtOH)- versus sucrose-maintained behavior when tested in separate groups, yet like the indirect agonist fluvoxamine, this selectively inverts when EtOH and food are concurrently available. Here, we extend these findings by examining varenicline and fluvoxamine effects under a multiple concurrent schedule where food and EtOH are concurrently available in different components: Component 1 where the food fixed-ratio was 25 and Component 2 where the food fixed-ratio was 75. The EtOH fixed-ratio was always 5. Food-maintained responding predominated in Component 1, while EtOH-maintained responding predominated in Component 2. In a second experiment, varenicline effects were assessed under a multiple schedule where food, then EtOH, then again food were available in separate 5-minute components with fixed-ratios of 5 for each reinforcement. In the multiple concurrent schedule, varenicline was more potent at reducing food- versus EtOH-maintained responding in both components and reduced EtOH-maintained responding more potently during Component 1 (when food was almost never earned) than in Component 2 (where food was often earned). Fluvoxamine was similarly potent at reducing food- and EtOH-maintained responding. Under the multiple schedule, varenicline, like fluvoxamine, more potently decreases EtOH- versus food maintained responding when only food or EtOH is available in separate components. These results demonstrate that selective effects on drug- versus alternative-maintained behavior depend on the schedule arrangement, and assays in which EtOH or an alternative is the only programmed reinforcement may overestimate the selectivity of treatments to decrease EtOH self-administration. Thus selective effects obtained under one assay may not generalize to another. Better understanding the behavioral mechanisms responsible for these results may help to guide pharmaco-therapeutic development for substance use disorders.

Gambling participation and low academic performance are related during adolescence, but the causal mechanisms underlying this link are unclear. It is possible that gambling participation impairs academic performance. Alternatively, the link between gambling participation and low academic performance could be explained by common underlying risk factors such as impulsivity and socio-family adversity. It could also be explained by other current correlated problem behaviors such as substance use. The goal of the present study was to examine whether concurrent and longitudinal links between gambling participation and low academic performance exist from age 14 to age 17 years, net of common antecedent factors and current substance use. A convenience sample of 766 adolescents (50.6% males) from a longitudinal twin sample participated in the study. Analyses revealed significant, albeit modest, concurrent links at both ages between gambling participation and academic performance. There was also a longitudinal link between gambling participation at age 14 and academic performance at age 17, which persisted after controlling for age 12 impulsivity and socio-family adversity as well as current substance use. Gambling participation predicts a decrease in academic performance during adolescence, net of concurrent and antecedent personal and familial risk factors.

Substance abuse in pregnant women. Experiences from a special child welfare clinic in Norway
Hjerkinn, Bjørg; Lindbæk, Morten; Rosvold, Elin Olaug
2007-01-01
Background Substance abuse during pregnancy may harm the foetus and can cause neonatal abstinence syndrome. Exposure to alcohol and other substances can influence the child for the rest of its life. A special child welfare clinic was set up in 1994 in Kristiansand, Norway, targeting pregnant women with substance abuse problems in the county of Vest-Agder. Pregnancy is not an indication for opioid replacement therapy in Norway, and one of the clinic's aims was to support the drug dependent women through their pregnancy without any replacements. The object of this paper is to describe concurrent health and social problems, as well as the predictors for stopping drug abuse, in the clinic's user group. Methods Retrospective cohort study. Data was gathered from the medical records of all 102 women seen in the clinic in the period between 1992 and 2002. The study includes 59 out of 60 women that were followed until their children were two years old or placed in alternative care, and a comparison group of twice the size. Both groups were presented with a questionnaire concerning both the pregnancy and health and socio-economic issues. Results Four (4.5 percent) of the women that completed their pregnancies did not manage to reduce their substance abuse. All the others reduced their substance abuse considerably. The odds ratio for stopping substance abuse within the first trimester was significantly associated with stopping smoking (O.R. 9.7) or being victims of rape (O.R. 5.3). Conclusion A low cost and low threshold initiative organised as a child welfare clinic may support women with substance abuse problems in their efforts to stop or reduce their substance abuse during pregnancy.

To determine: (a) the prevalence of physical fighting while under the influence of alcohol or drugs, and (b) the associations among demographic factors, other risk behaviors, and physical fighting while under the influence of substances. Cross-sectional analysis of The National Longitudinal Study of Adolescent Health (Add Health) 1994-1995, a school-based, nationally representative survey of 6504 7th to 12th graders. The dependent outcome variables of interest were: "The most recent time you got into a fight, had you been drinking?" and "Have you ever gotten into a fight when you had been using drugs?" Independent variables included: demographics, adolescent characteristics and risk behaviors, home environment, and peer substance use. Univariate and bivariate analyses, and logistic regressions, using SUDAAN, were performed for the two outcome behaviors for the overall sample (p = .05). Eleven percent of both drinkers (n = 1110) and drug users (n = 1869) reported being under the influence while fighting. These adolescents were significantly more likely to injure or sustain injury than their counterparts. Selling drugs, gang fighting, and peer substance use were significantly associated with both outcomes. A significant proportion of adolescents who use substances also engage in physical fighting while under the influence. Health providers should counsel their patients about the potential for injury and be mindful that concurrent fighting and substance use may be markers for other more high-risk delinquent behaviors.

Reduced posterior mesofrontal cortex activation by risky rewards in substance-dependent patients.

2008-05-01
Substance-dependent individuals show disadvantageous decision-making, as well as alterated frontocortical recruitment when performing experimental tasks. We investigated whether substance-dependent patients (SDP) would show blunted recruitment of posterior mesofrontal cortex (PMC) by a conflict between concurrently increasing reward and risk of penalty in a monetary game of "chicken." SDP and controls performed: motor control (no reward) trials, guaranteed reward trials in which reward was not at risk, and risky trials where subjects were required to terminate their reward accrual before a secret varying time limit or else "bust" and forfeit that trial's winnings (low penalty) or the current trial's winnings plus an equal amount of previous winnings (high penalty). Reward accrual duration at risk of "busting" correlated negatively with trait neuroticism. The contrast between winning guaranteed reward versus non-reward activated the caudate head bilaterally in SDP but not controls. Accumulation of money at risk of low- or high-penalty (contrasted with accumulating guaranteed money) activated the PMC in both groups, but with a greater magnitude and more anterior extent in controls. Pre-decision signal increase in a PMC volume of interest negatively correlated with risk-taking in low-penalty trials, and was blunted in SDP relative to controls under both penalty conditions after controlling for individual differences in actual risk-taking and the higher neuroticism of SDP. These data suggest that SDP are characterized by a combination of: (a) striatal hypersensitivity to reward, and (b) under-recruitment of the specialized conflict-monitoring circuitry of the PMC when reward entails potential penalties.

Aims The French health authority (ANSM) is responsible for monitoring medicinal and other drug dependencies. To support these activities, the ANSM manages a network of 13 drug dependence evaluation and information centres (Centres d'Evaluation et d'Information sur la Pharmacodépendance ‐ Addictovigilance ‐ CEIP‐A) throughout France. In 2006, the Nantes CEIP‐A created a new tool called the EGAP (Echelle de GrAvité de la Pharmacodépendance‐ drug dependence severity scale) based on DSM IV criteria. This tool allows the creation of a substance use profile that enables the drug dependence severity to be homogeneously quantified by assigning a score to each substance indicated in the reports from health professionals. This article describes the validation and psychometric properties of the drug dependence severity score obtained from the scale ( Clinicaltrials.gov NCT01052675). Method The validity of the EGAP construct, the concurrent validity and the discriminative ability of the EGAP score, the consistency of answers to EGAP items, the internal consistency and inter rater reliability of the EGAP score were assessed using statistical methods that are generally used for psychometric tests. Results The total EGAP score was a reliable and precise measure for evaluating drug dependence (Cronbach alpha = 0.84; ASI correlation = 0.70; global ICC = 0.92). In addition to its good psychometric properties, the EGAP is a simple and efficient tool that can be easily specified on the official ANSM notification form. Conclusion The good psychometric properties of the total EGAP score justify its use for evaluating the severity of drug dependence. PMID:27302554

While the detrimental effects of concurrent substance use disorders (SUDs) are now being well documented, very few studies have examined this comorbidity among women with posttraumatic stress disorder (PTSD). Data for these analyses were derived from the "Women and Trauma" study conducted within the National Drug Abuse Treatment Clinical Trials Network. Women with full or subthreshold PTSD and co-occurring cannabis use disorder (CUD) and cocaine use disorder (COD; N=99) were compared to their counterparts with co-occurring CUD only (N=26) and co-occurring COD only (N=161) on rates of trauma exposure, psychiatric disorders, psychosocial problems, and other substance use utilizing a set of multivariate logistic regressions. In models adjusted for age and race/ethnicity, women with PTSD and COD only were significantly older than their counterparts with CUD only and concurrent CUD+COD. Relative to those with CUD only, women with concurrent CUD+COD had higher odds of adult sexual assault. Relative to those with COD only, women with concurrent CUD+COD had higher odds of alcohol use disorder in the past 12months. Finally, relative to those with CUD only, women with COD only had higher odds of ever being arrested/convicted and adult sexual assault. The higher rates of adult sexual assault and alcohol use disorder among those with concurrent CUD+COD suggest the need for trauma-informed approaches that can respond to the needs of this dually-diagnosed population. Moreover, the causal link between repeated traumatic stress exposure and polysubstance use requires further examination. Copyright © 2017 Elsevier Inc. All rights reserved.

While the co-prevalence of eating disorders (ED) has been documented in individuals with substance use disorders (SUD), little is known about the co-occurrence of other disorders in this population. Examining this issue is critical for public health policy and treatment success. To identify and evaluate the co-occurrence of ED and other psychiatric disorders in men and women with SUD. The sample consisted of individuals seeking treatment for substance use. Semi-structured interviews and the CAMH Concurrent Disorders Screener were completed to assess DSM-IV psychopathology. Chi-square analyses suggested that more women scored positive for ED than men, EDs were more prevalent in both genders than in the general population, and the co-occurrence of other disorders was higher for clients with both SUD and ED than with SUD. Individuals with both SUD and ED appear to have multiple needs that may not be readily assessed by existing addiction treatment programs. Assessment issues, treatment, potential prevention and health promotion implications are addressed.

Individuals who are homeless or vulnerably housed have a higher prevalence of concurrent disorders, defined as having a mental health diagnosis and problematic substance use, compared to the general housed population. The study objective was to investigate the effect of having concurrent disorders on health care utilization among homeless or vulnerably housed individuals, using longitudinal data from the Health and Housing in Transition Study. In 2009, 1190 homeless or vulnerably housed adults were recruited in Ottawa, Toronto, and Vancouver, Canada. Participants completed baseline interviews and four annual follow-up interviews, providing data on sociodemographics, housing history, mental health diagnoses, problematic drug use with the Drug Abuse Screening Test (DAST-10), problematic alcohol use with the Alcohol Use Disorders Identification Test (AUDIT), chronic health conditions, and utilization of the following health care services: emergency department (ED), hospitalization, and primary care. Concurrent disorders were defined as the participant having ever received a mental health diagnosis at baseline and having problematic substance use (i.e., DAST-10 ≥ 6 and/or AUDIT ≥ 20) at any time during the study period. Three generalized mixed effects logistic regression models were used to examine the independent association of having concurrent disorders and reporting ED use, hospitalization, or primary care visits in the past 12 months. Among our sample of adults who were homeless or vulnerably housed, 22.6% (n = 261) reported having concurrent disorders at baseline. Individuals with concurrent disorders had significantly higher odds of ED use (adjusted odds ratio [AOR] = 1.71; 95% confidence interval [CI], 1.4-2.11), hospitalization (AOR = 1.45; 95% CI, 1.16-1.81), and primary care visits (AOR = 1.34; 95% CI, 1.05-1.71) in the past 12 months over the four-year follow-up period, after adjusting for potential confounders. Concurrent disorders were associated with higher rates of health care utilization when compared to those without concurrent disorders among homeless and vulnerably housed individuals. Comprehensive programs that integrate mental health and addiction services with primary care as well as community-based outreach may better address the unmet health care needs of individuals living with concurrent disorders who are vulnerable to poor health outcomes.

This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. Concurrent and predictive validity tests showed that all 4 brief scales-hopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)-were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents "at risk," one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed. Copyright © 2012 by the Research Society on Alcoholism.

Background A better understanding of how to measure motivation to change and how it relates to behavior change in patients with drug and alcohol dependence would broaden our understanding of the role of motivation in addiction treatment. Methods Two multi-site, randomized clinical trials comparing brief motivational interventions with standard care were conducted in the National Institute on Drug Abuse Clinical Trials Network. Patients with primary drug dependence and alcohol dependence entering outpatient treatment participated in a study of either Motivational Enhancement Therapy (n=431) or Motivational Interviewing (n=423). The construct, concurrent, and predictive validity of two composite measures of motivation to change derived from the University of Rhode Island Change Assessment (URICA): Readiness to Change (RTC) and Committed Action (CA) were evaluated. Results Confirmatory factor analysis confirmed the a priori factor structure of the URICA. RTC was significantly associated with measures of addiction severity at baseline (r=.12-.52, p<.05). Although statistically significant (p<.01), the correlations between treatment outcomes and RTC were low (r=-.15 and -18). Additional analyses did not support a moderating or mediating effect of motivation on treatment retention or substance use. Conclusions The construct validity of the URICA was confirmed separately in a large sample of drug- and alcohol-dependent patients. However, evidence for the predictive validity of composite scores was very limited and there were no moderating or mediating effects of either measure on treatment outcome. Thus, increased motivation to change, as measured by the composite scores of motivation derived from the URICA, does not appear to influence treatment outcome. PMID:19157723

This article examines noncausal associations between high school seniors' alcohol and marijuana use status and rates of self-reported unsafe driving in the past 12 months. Analyses used data from 72,053 students collected through annual surveys of nationally representative cross-sectional samples of U.S. 12th-grade students from 1976 to 2011. Two aspects of past-12-month alcohol and marijuana use were examined: (a) use frequency and (b) status as a nonuser, single substance user, concurrent user, or simultaneous user. Measures of past-12-month unsafe driving included any tickets/warnings or accidents, as well as tickets/warnings or accidents following alcohol or marijuana use. Analyses explored whether an individual's substance use frequency and simultaneous use status had differential associations with their rate of unsafe driving. Higher substance use frequency (primarily alcohol use frequency) was significantly and positively associated with unsafe driving. The rate of engaging in any unsafe driving was also significantly and positively associated with simultaneous use status, with the highest rate associated with simultaneous use, followed by concurrent use, followed by use of alcohol alone. Individuals who reported simultaneous use most or every time they used marijuana had the highest likelihood of reporting unsafe driving following either alcohol or marijuana use. This article expands the knowledge on individual risk factors associated with unsafe driving among teens. Efforts to educate U.S. high school students (especially substance users), parents, and individuals involved in prevention programming and driver's education about the increased risks associated with various forms of drug use status may be useful.

Mobile phone use has increased dramatically and concurrent with rapid developments in mobile phone-based health interventions. The integration of text messaging interventions promises to optimise the delivery of care for persons with substance dependence with minimal disruption to clinical workflows. We conducted a systematic review to assess the acceptability, feasibility and clinical impact of text messaging interventions for persons with illicit drug and alcohol dependence. Studies were required to evaluate the use of text messaging as an intervention for persons who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition criterion for a diagnosis of illicit drug and/or alcohol dependence. Authors searched for articles published to date in MEDLINE (pubmed.gov), the Cochrane Library, EMBASE, CINAHL, Google Scholar and PsychINFO. Eleven articles met the search criteria for this review and support the acceptability and feasibility of text messaging interventions for addressing illicit drug and alcohol dependence. Most studies demonstrated improved clinical outcomes, medication adherence and engagement with peer support groups. Text messaging interventions also intervened on multiple therapeutic targets such as appointment attendance, motivation, self-efficacy, relapse prevention and social support. Suggestions for future research are described, including intervention design features, clinician contact, privacy measures and integration of behaviour change theories. Text messaging interventions offer a feasible platform to address a range of substances (i.e. alcohol, methamphetamine, heroin and alcohol), and there is increasing evidence supporting further larger-scale studies.

Objective To evaluate the efficacy and safety of osmotic-release methylphenidate (OROS-MPH) compared to placebo for attention deficit hyperactivity disorder (ADHD) and impact on substance treatment outcomes in adolescents concurrently receiving cognitive behavioral therapy (CBT) for substance use disorders (SUD). Method 16-week randomized controlled multi-site trial of OROS-MPH + CBT versus placebo + CBT in 303 adolescents (aged 13-18), meeting DSM-IV diagnostic criteria for ADHD and SUD. Primary outcomes: (1) ADHD- clinician-administered ADHD Rating Scale (ADHD-RS), adolescent informant; (2) Substance- adolescent reported days of use in the past 28 days. Secondary outcome measures included parent ADHD-RS and weekly urine drug screens (UDS). Results There were no group differences on reduction in ADHD-RS scores (OROS-MPH: −19.2, 95% confidence interval [CI], −17.1 to −21.2; placebo,−21.2, 95% CI, −19.1 to −23.2) or reduction in days of substance use (OROS-MPH: −5.7 days, 95% CI, 4.0-7.4; placebo: −5.2 days, 95% CI, 3.5-7.0). Some secondary outcomes favored OROS-MPH including lower parent ADHD-RS scores at 8 (mean difference [md]=4.4, 95% CI, 0.8-7.9) and 16 weeks (md=6.9; 95% CI, 2.9-10.9) and more negative UDS in OROS-MPH (mean=3.8) compared to placebo (mean=2.8; P=0.04). Conclusions OROS-MPH did not show greater efficacy than placebo for ADHD or on reduction in substance use in adolescents concurrently receiving individual CBT for co-occurring SUD. However, OROS-MPH was relatively well tolerated and was associated with modestly greater clinical improvement on some secondary ADHD and substance outcome measures. PMID:21871372

The misuse, abuse and diversion of controlled substances have reached epidemic proportion in the United States. Contributing to this problem are providers who over-prescribe these substances. Using one state's prescription drug monitoring program, we describe a series of metrics we developed to identify providers manifesting unusual and uncustomary prescribing practices. We then present the results of a preliminary effort to assess the concurrent validity of these algorithms, using death records from the state's vital records database pertaining to providers who wrote prescriptions to patients who then died of a medication or drug overdose within 30 days. Metrics manifesting the strongest concurrent validity with providers identified from these records related to those who co-prescribed benzodiazepines (e.g., valium) and high levels of opioid analgesics (e.g., oxycodone), as well as those who wrote temporally overlapping prescriptions. We conclude with a discussion of a variety of uses to which these metrics may be put, as well as problems and opportunities related to their use.

Objective The purpose of this report was to examine the course of smoking among pregnant women with concurrent substance use, and to assess the impact of depression on smoking. Methods Data were gathered as part of a randomized controlled trial assessing the efficacy of substance abuse treatment in pregnant women. Women (n=176) were recruited before 28 completed weeks of pregnancy, and followed until 3 months postpartum. Depression was assessed using the Inventory of Depressive Symptomatology and the MINI Neuropsychiatric Interview. Our outcome was the average number of cigarettes smoked per day. Linear mixed effects regression was used to measure differential changes in smoking. Results 66% of women smoked in the three months before pregnancy, 42% of pre-pregnancy smokers achieved abstinence before delivery and 60% of the baseline cohort smoked postpartum. Smoking did not differ significantly between depressed and non-depressed groups. After delivery both groups increased smoking at similar rates. Conclusion Smoking was common among our cohort of pregnant women with a history of substance use. Women were able to discontinue or decrease smoking during pregnancy, but were likely to resume or increase smoking postpartum. Having clinically significant depressive symptoms or a diagnosis of depression did not have an obvious effect on smoking behaviors. PMID:24447885

Non-dependent alcohol and substance use patterns are prevalent among men who have sex with men (MSM), yet few effective interventions to reduce their substance use are available for these men. We evaluated whether an adapted brief counseling intervention aimed at reducing HIV risk behavior was associated with secondary benefits of reducing substance use among episodic substance-using MSM (SUMSM). 326 episodic SUMSM were randomized to brief Personalized Cognitive Counseling (PCC) intervention with rapid HIV testing or to rapid HIV testing only control. Both arms followed over 6 months. Trends in substance use were examined using GEE Poisson models with robust standard errors by arm. Reductions in frequency of use were examined using ordered logistic regression. In intent-to-treat analyses, compared to men who received rapid HIV testing only, we found men randomized to PCC with rapid HIV testing were more likely to report abstaining from alcohol consumption (RR=0.93; 95% CI=0.89-0.97), marijuana use (RR=0.84; 95% CI=0.73-0.98), and erectile dysfunction drug use (EDD; RR=0.51; 95% CI=0.33-0.79) over the 6-month follow-up. PCC was also significantly associated with reductions in frequency of alcohol intoxication (OR=0.58; 95% CI=0.36-0.90) over follow-up. Furthermore, we found PCC was associated with significant reductions in number of unprotected anal intercourse events while under the influence of methamphetamine (RR=0.26; 95% CI=0.08-0.84). The addition of adapted PCC to rapid HIV testing may have benefits in increasing abstinence from certain classes of substances previously associated with HIV risk, including alcohol and EDD; and reducing alcohol intoxication frequency and high-risk sexual behaviors concurrent with methamphetamine use.

The behavioural response following infusion of a novel, stable substance P (SP) analogue, DiMe-C7, into the ventral tegmental area (VTA) of rats was characterized and contrasted with the response to an equal dose of the parent compound SP. DiMe-C7 produced a longer-lasting behavioural stimulation than SP as evidenced in several behaviours, including locomotor activity, wet dog shakes, rearing and grooming. DiMe-C7-induced locomotor activity and rearing were potentiated by concurrent peripheral administration of D-amphetamine and blocked by pretreatment with haloperidol. Such responses to DiMe-C7 may thus be dependent upon dopaminergic activity. When given immediately following VTA infusion of DiMe-C7, morphine decreased, while naloxone had no effect upon most behavioural measures. The effect of methysergide on DiMe-C7 or SP into the substantia nigra reticulata produced a pattern of responses similar to nature to those produced by VTA infusion but different with respect to time course. These findings suggest that DiMe-C7 is a metabolically stable analogue of substance P which manifests prolonged actions on behaviour when centrally administered. Further, a role for central dopaminergic mechanisms is implicated in DiMe-C7-induced behavioural action.

A sofosbuvir/ledipasvir combination is part of a first-line treatment of hepatitis C. However, in patients concurrently treated with amiodarone, cardiac side effects have been described, resulting in an official warning in 2015 by the American Food and Drug Administration and the European Medicines Agency when combining those substances. This deprived numerous hepatitis C patients with concurrent cardiovascular problems of receiving this highly effective treatment. Here we present a treatment alternative with an elbasvir/grazoprevir regimen, based on our successful treatment of a patient under concurrent amiodarone therapy. Our observations indicate that patients treated with amiodarone can finally benefit from effective antiviral therapy. PMID:29606942

Objective It is imperative that research identifies factors related to depression among individuals in substance use treatment, as depression is associated with substance use relapse. Dispositional mindfulness and spirituality may bear an important role in the relationship between depression and substance use. Method Using preexisting patient medical records (N = 105), the current study investigated dispositional mindfulness and spirituality in relation to depressive symptom clusters (affective, cognitive, and physiological) among men in residential substance use treatment. The mean age of the sample was 41.03 (standard deviation = 10.75). Results Findings demonstrated that dispositional mindfulness and spirituality were negatively associated with depressive symptoms. After controlling for age, alcohol use, and drug use, dispositional mindfulness remained negatively associated with all of the depression clusters. Spirituality only remained associated with the cognitive depression cluster. Conclusion Mindfulness-based interventions may hold promise as an effective intervention for reducing substance use and concurrent depressive symptoms. PMID:25522300

To assess the performance of Diagnostic Cost Groups (DCGs) in explaining variation in concurrent utilization for a defined subgroup, patients with substance abuse (SA) disorders, within the Department of Veterans Affairs (VA). A 60 percent random sample of veterans who used health care services during Fiscal Year (FY) 1997 was obtained from VA administrative databases. Patients with SA disorders (13.3 percent) were identified from primary and secondary ICD-9-CM diagnosis codes. Concurrent risk adjustment models were fitted and tested using the DCG/HCC model. Three outcome measures were defined: (1) "service days" (the sum of a patient's inpatient and outpatient visit days), (2) mental health/substance abuse (MH/SA) service days, and (3) ambulatory provider encounters. To improve model performance, we ran three DCG/HCC models with additional indicators for patients with SA disorders. To create a single file of veterans who used health care services in FY 1997, we merged records from all VA inpatient and outpatient files. Adding indicators for patients with mild/moderate SA disorders did not appreciably improve the R-squares for any of the outcome measures. When indicators were added for patients with severe SA who were in the most costly category, the explanatory ability of the models was modestly improved for all three outcomes. Modifying the DCG/HCC model with additional markers for SA modestly improved homogeneity and model prediction. Because considerable variation still remained after modeling, we conclude that health care systems should evaluate "off-the-shelf" risk adjustment systems before applying them to their own populations.
Heavy metal poisoning and concurrent septicemia

Poisoning occurring in animals caused by agents such as arsenic, lead, tin, and other necrotizing substances is often accompanied by a Clostridial septicemia. The toxins of the Clostridia involved bring about clinical signs and pathologic changes that differ considerably from those caused by the poisonous agent; thereby overshadowing those produced by the poison. The Clostridia involved most frequently are Clostridium septicum, sordelli, and novyi. Therapy in cases of poisoning by necrotizing substances should include measures to prevent possible Clostridial involvement.

The majority of Drug Treatment Court (DTC) research has examined the impact of DTCs on criminal recidivism. Comparatively little research has addressed the association between DTC participation and engagement with community-based health and social services. The present study investigated changes in participant involvement with outpatient healthcare and income assistance within a DTC cohort. We hypothesized that involvement with community-based (outpatient) health and social services would increase post-DTC participation, and that service levels would be higher among program graduates and offenders with histories of co-occurring mental and substance use disorders. Participants were 631 offenders at the DTC in Vancouver, Canada (DTCV). Administrative data representing hospital, outpatient medical care, and income assistance were examined one-year pre/post program to assess differences over time. Generalized estimating equations were used to investigate the association between changes in service use and program involvement. We also examined the relationship between level of service use and offender characteristics. Members of the cohort were disproportionately Aboriginal (33 %), had been sentenced 2.7 times in the 2 years preceding their index offence, and 50 % had been diagnosed with a non substance-related mental disorder in the five years preceding the index offence. The mean number of outpatient services post DTCV was 51, and the mean amount of social assistance paid was $5,897. Outpatient service use increased following exposure to DTCV (Adjusted Rate Ratio (ARR) = 1.45) and was significantly higher among women (ARR = 1.47), program graduation (ARR = 1.23), and those previously diagnosed with concurrent substance use and mental disorders (ARR = 4.92). Overall, hospital admissions did not increase post-program, although rates were significantly higher among women (ARR = 1.76) and those with concurrent disorders (ARR = 2.71). Income assistance increased significantly post program (ARR = 1.16), and was significantly higher among women (ARR = 1.03), and those diagnosed with substance use disorders (ARR = 1.42) and concurrent disorders (ARR = 1.72). These findings suggest that the DTCV was a catalyst for increased participant engagement with community health and social supports, and that rates of service use were consistently higher among women and individuals with concurrent disorders. Research is needed to investigate the potential link between health and social support and reductions in recidivism associated with DTCs.
A comparative study of self-regulation in substance dependent and non-dependent individuals.

Several factors influence the beginning and maintenance of substance use. The purpose of this study was to examine as well as to compare 'self-regulation' in both substance dependent and non-substance dependent individuals. In a cross-sectional study 228 (118 substance dependent and 110 with no history of using substance) participants aged 16-55 were recruited. All of the participants were asked to complete the Self-Regulation Inventory (SRI-25) and a demographic characteristics data checklist. Data was analyzed using descriptive statistics (frequency, mean and standard deviation) and the t-test. The results showed significant differences between substance dependent and non- substance dependent groups in all the scales of the self-regulation inventory including positive actions, controllability, expression of feelings and needs, assertiveness, and well-being seeking (p<0.01). Self-regulation and self-control skills in drug dependent individuals are lower than those without substance dependence individuals. It is concluded that substance use may related to a deficiency in self-control and regulation of feelings. Therefore, for prevention and treatment of substance dependence disorder, it is necessary to work out and exploit strategies that include the improvement of self-regulation.

Objectives We examined behavioral and cognitively-based quit processes among concurrent alcohol and tobacco users and assessed whether smoking and drinking were differentially influenced. Methods Participants were 200 treatment-seeking smokers (37.50% female; Mage = 30.72; SD = 12.68) who reported smoking an average of 10 or more cigarettes daily for at least one year. Results Barriers to cessation (BCS) and reasons for quitting (RFQ) were generally correlated with substance use. BCS moderated the relationship between quit methods and cigarette use such that quit methods were negatively associated with smoking, particularly among those with more BCS. RFQ moderated the association between quit methods and cigarette use such that quit methods were negatively linked with smoking among those with fewer RFQ, but positively linked with smoking among those with more RFQ. Two 3-way interactions emerged. The first 3-way indicated that among individuals with fewer RFQ, quit methods was negatively associated with smoking, and this was strongest among those with more BCS. However, among those with more RFQ, smoking and quit methods were positively associated, particularly among those with more BCS. The second 3-way showed that among those with fewer RFQ, quit methods was negatively linked with drinking frequency, and this was strongest among those with more BCS. However, among those with fewer BCS, drinking and quit methods were positively linked. Conclusions The relationship between behavioral and cognitively-based quit processes and substance use is not straightforward. There may be concurrent substance-using individuals for whom these processes might be associated with increased substance use. PMID:26949566

Background Substance use is highly prevalent among transgender (trans*) females and has been associated with negative health outcomes, including HIV infection. Little is known about psychosocial risk factors that may influence the onset of substance use among trans*female youth, which can contribute to health disparities during adulthood. Methods We conducted a secondary data analysis of a study on HIV risk and resilience among trans*female youth (N=292). Prevalence of substance use was assessed and multivariable logistic regression models were used to examine the relationship between posttraumatic stress disorder (PTSD), psychological distress, gender-related discrimination, parental drug or alcohol problems (PDAP) and multiple substance use outcomes. Results Most (69%) of the trans*female youth reported recent drug use. In multivariable analyses, those with PTSD had increased odds of drug use [AOR=1.94 (95%CI=1.09–3.44)]. Those who experienced gender-related discrimination had increased odds of drug use [AOR=2.28 (95%CI=1.17–4.44)], drug use concurrent with sex [AOR=2.35 (95%CI=1.11–4.98)] and use of multiple drugs [AOR=3.24 (95%CI=1.52–6.88)]. Those with psychological distress had increased odds of using multiple heavy drugs [AOR=2.27 (95%CI=1.01–5.12)]. Those with PDAP had increased odds of drugs use [AOR=2.62 (95%CI=1.43–4.82)], drug use concurrent with sex [AOR=2.01 (95%CI, 1.15–3.51)] and use of multiple drugs [AOR=2.10 (95%CI=1.22–3.62)]. Conclusions Substance use is highly prevalent among trans*female youth and was significantly associated with psychosocial risk factors. In order to effectively address substance use among trans*female youth, efforts must address coping related to gender-based discrimination and trauma. Furthermore, structural level interventions aiming to reduce stigma and gender-identity discrimination might also be effective. PMID:25548025

Air pollution by industry and motor vehicles, the use of coal ash for the construction of residential and nonresidential buildings, and the presence of dead zones in the residential sector are the main factors of carcinogenic risk to human health. Natural factors (such as topography and prevailing wind directions) can weaken or strengthen technogenic factors. Based on the estimate of pollutant concentrations in the snow cover of Barnaul, we reveal residential areas that are located at the crossroads of atmospheric transport of carcinogenic substances and characterized by concentrations considerably exceeding the maximum allowable concentration. These areas are characterized by the integral accumulation of carcinogenic substances concurrently from multiple sources; for almost any wind rose, the impact of one of the pollution sources is observed throughout the year. The assessment of the carcinogenic risk for a territory depends much on the correlation between local topography and the height of apartments above ground level. Using cancer register data for Barnaul, we reveal an increased level of the incidence of malignant neoplasms in people living in high-rise buildings located in areas with a sharp change in topography (such as ledges, hills, and lowlands). This may occur due to stagnant zones and wind shadows; under certain correlation between topography and the height and shape of buildings, carcinogenic substances accumulate maximally.

Acceptability and willingness to both take and pay for HIV self-tests (HIVSTs) in US neighbourhoods with high rates of HIV infection are not well understood. We surveyed 1,535 individuals about acceptability and willingness to take and pay for an HIVST in a predominately African American neighbourhood with 3% HIV seroprevalence. We recruited individuals presenting for HIV screening services in a community-based programme. Latent class analysis (LCA) grouped individuals with similar patterns of HIV-risk behaviours and determined which groups would be most willing to use and buy HIVSTs. Nearly 90% of respondents were willing to use an HIVST; 55% were willing to buy HIVSTs, but only 23% were willing to pay the market price of US $40. Four distinct groups emerged and were characterized by risk behaviours: (1) low risk ( N = 324); (2) concurrent partnerships ( N = 346); (3) incarceration and substance use ( N = 293); and (4) condomless sex/multiple partners ( N = 538). Individuals in the low-risk class were less willing to self-test compared to concurrent sexual partners (OR = 0.39, p = .003) and incarceration and substance use (OR = 0.46, p = .011) classes. There were no significant differences across classes in the amount individuals were willing to pay for an HIVST. HIVSTs were overwhelmingly acceptable but cost prohibitive; most participants were unwilling to pay the market rate of US $40. Subsidizing and implementing HIVST programmes in communities with high rates of infection present a public health opportunity, particularly among individuals reporting condomless sex with multiple partners, concurrent sexual partnerships and those with incarceration and substance use histories.

Tributyltin and 1, 1-dichloro-2, 2 bis (p-chlorophenyl) ethylene (p,p'-DDE) have been ubiquitously distributed over the world. In Japan, p,p'-DDE and tributyltin are ingested through marine products, in which these substances are accumulated through bio-concentration and the food chain. However, the consequence of potential combined hazards of these substances remains unknown. Therefore, the effects of concurrent exposure to 125 ppm p,p'-DDE and 25 ppm tributyltin were investigated in immature male Wistar rats by oral administration during puberty. In this study, tributyltin promoted the growth of pubertal male rats, while p,p'-DDE itself did not affect the growth but inhibited the growth enhancement by tributyltin. Furthermore, tributyltin reduced thymus weight but p,p'-DDE also prevented this weight reduction. Neither development of male sexual accessory organs nor sexual maturation was affected even by concurrent exposure to p,p'-DDE and tributyltin. No significant changes of serum testosterone, luteinizing hormone, follicle-stimulating hormone concentrations, and epididymal sperm numbers were observed with the administration of p,p'-DDE and/or tributyltin. These results indicate that sexual maturation, male reproductive organ development and sperm production is scarcely affected in immature male Wistar rats even by concurrent exposure to p,p'-DDE and tributyltin at a daily dose of ca. 2 mg/kg tributyltin and 10 mg/kg p,p'-DDE. Moreover, the simultaneous administration of p,p'-DDE with tributyltin counterbalanced the effects that were attributed to tributyltin alone.

Temporal associations in the relationship between emotional-behavioral difficulty and academic achievement were explored in 2 samples followed from 6th through 8th grade. The first sample comprised 280 students entering an economically disadvantaged urban middle school and the second comprised 318 students entering an affluent suburban middle school. Among disadvantaged youth, emotional indices were concurrently associated with poorer achievement while prospective associations between substance use and achievement were evident. For privileged adolescents, only a significant concurrent relationship emerged between social anxiety and achievement, although nonsignificant trends in the data suggest other, albeit weak, associations. The findings are discussed in terms of similarities and differences in these temporal associations across 2 samples representing extremes of the socioeconomic continuum. PMID:23129975

In this study, we used data from Add Health Waves II and III to compare men who had been incarcerated to those who had not, and examined whether incarceration was associated with increased numbers of sexual partners and increased odds of concurrent partnerships. We used multivariate regression and propensity-score matching to compare sexual behavior of Wave III male respondents who had been incarcerated with those who had not, and compared sexual behavior at Wave II to identify differences in sexual behavior prior to incarceration. Incarceration was associated with an increased rate of lifetime sexual partnership, but this was attenuated by substance use. Criminal justice involvement was associated with increased odds of having partners who report concurrent partnerships, but no further increase was seen with incarceration. There were no significant sexual behavior differences prior to incarceration. These results suggest that the criminal justice system and substance use may interact to shape sexual behavior.

Background Comorbid substance use disorders (SUD) are associated with increased illness severity and functional impairment among adolescents with bipolar disorder (BD). Previous psychosocial treatment studies have excluded adolescents with both BD and SUD. Studies suggest that integrated interventions are optimal for adults with BD and SUD. Methods We modified family-focused treatment for adolescents with BD (FFT-A) in order to explicitly target comorbid SUD (FFT-SUD). Ten adolescents with BD who had both SUD and an exacerbation of manic, depressed, or mixed symptoms within the last 3 months were enrolled. FFT-SUD was offered as an adjunct to pharmacotherapy, with a target of 21 sessions over 12 months of treatment. The FFT-SUD manual was iteratively modified to integrate a concurrent focus on SUD. Results Six subjects completed a mid-treatment 6-month assessment (after a mean of 16 sessions was completed). Of the 10 subjects, 3 dropped out early ( after ≤ 1 session); in the case of each of these subjects, the participating parent had active SUD. No other subjects in the study had a parent with active SUD. Preliminary findings suggested significant reductions in manic symptoms and depressive symptoms and improved global functioning. Reduction in cannabis use was modest and did not reach significance. Limitations Limitations included a small sample, open treatment, concurrent medications, and no control group. Conclusions These preliminary findings suggest that FFT-SUD is a feasible intervention, particularly for youth without parental SUD. FFT-SUD may be effective in treating mood symptoms, particularly depression, despite modest reductions in substance use. Integrating motivation enhancing strategies may augment the effect of this intervention on substance use. Additional strategies, such as targeting parental substance use, may prevent early attrition.

Energy drinks and alcohol-related risk among young adults.
Caviness, Celeste M; Anderson, Bradley J; Stein, Michael D
2017-01-01
Energy drink consumption, with or without concurrent alcohol use, is common among young adults. This study sought to clarify risk for negative alcohol outcomes related to the timing of energy drink use. The authors interviewed a community sample of 481 young adults, aged 18-25, who drank alcohol in the last month. Past-30-day energy drink use was operationalized as no-use, use without concurrent alcohol, and concurrent use of energy drinks with alcohol ("within a couple of hours"). Negative alcohol outcomes included past-30-day binge drinking, past-30-day alcohol use disorder, and drinking-related consequences. Just over half (50.5%) reported no use of energy drinks,18.3% reported using energy drinks without concurrent alcohol use, and 31.2% reported concurrent use of energy drinks and alcohol. Relative to those who reported concurrent use of energy drinks with alcohol, and controlling for background characteristics and frequency of alcohol consumption, those who didn't use energy drinks and those who used without concurrent alcohol use had significantly lower binge drinking, negative consequences, and rates of alcohol use disorder (P < .05 for all outcomes). There were no significant differences between the no-use and energy drink without concurrent alcohol groups on any alcohol-related measure (P > .10 for all outcomes). Concurrent energy drink and alcohol use is associated with increased risk for negative alcohol consequences in young adults. Clinicians providing care to young adults could consider asking patients about concurrent energy drink and alcohol use as a way to begin a conversation about risky alcohol consumption while addressing 2 substances commonly used by this population.

Background Cigarette smoking is common in adolescents with attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD). However, little is known about the relationship between cigarette and cannabis use trajectories in the context of treatment for both ADHD and SUD. To address this research gap, we report collateral analyses from a 16-week randomized, controlled trial (n=303) of osmotic-release methylphenidate (OROS-MPH) in adolescents with ADHD concurrently receiving cognitive behavioral therapy (CBT) targeting non-nicotine SUD. Methods Participants completed cigarette and cannabis use self-report at baseline and throughout treatment. Analyses were performed to explore the relationships between cigarette smoking, cannabis use, and other factors, such as medication treatment assignment (OROS-MPH versus placebo). Results Baseline (pre-treatment) cigarette smoking was positively correlated with cannabis use. Negligible decline in cigarette smoking during treatment for non-nicotine SUD was observed in both medication groups. Regular cigarette and cannabis users at baseline who reduced their cannabis use by >50% also reduced cigarette smoking (from 10.8±1.1 to 6.2±1.1 cigarettes per day). Conclusions Findings highlight the challenging nature of concurrent cannabis and cigarette use in adolescents with ADHD, but demonstrate that changes in use of these substances during treatment may occur in parallel.

Substance use and violent behavior in women with antisocial personality disorder.
Lewis, Catherine F
2011-01-01
The purpose of this study was to examine the relationship between substance abuse and dependence and violent behavior in a sample of incarcerated women with antisocial personality disorder (ASPD). Among male populations, substance dependence is associated with aggression and criminal behavior. Individuals with ASPD have more severe substance dependence, including higher symptom counts, earlier age of onset, and more frequent co-morbidity. Incarcerated women have a high prevalence of ASPD and substance dependence, but there has been little detailed work regarding addiction severity. Similarly, work on association of substance abuse and dependence with specific violent behaviors has been limited. This study examined a group of 41 mid-sentence female felons with a diagnosis of ASPD to determine associations with substance abuse and dependence. Data were gathered through administration of the Semi-Structured Assessment of the Genetics of Alcoholism II (SSAGA II). Substance dependence was highly prevalent (i.e., alcohol dependence, 56.1%; opiate dependence, 48.8%; cocaine dependence, 61.0%). While specific diagnoses were not associated with violent behavior and offending, symptom severity (i.e., age of onset, symptom count, co-morbidity) was associated with violent behavior in women dependent on opiates, alcohol, and cocaine. Arrest for an assault 1 was associated with alcohol dependence and opiate dependence. These data suggest that measurement of symptom severity and co-morbidity is important in assessing violent behavior in incarcerated women with ASPD. These findings are potentially important in examining non-incarcerated, substance-dependent women. Copyright © 2011 John Wiley & Sons, Ltd.

Cannabis use disorder (CUD) is frequently associated with concurrent substance use and/or comorbid substance use disorders (SUDs); however there is little specificity with regard to commonly abused individual drug types/classes. This study therefore aimed to provide insight into the degree of these co-occurring relationships across several specific newer and older generation illicit and prescription drugs. 36,309 adults aged 18+ from wave 3 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were assessed. Weighted cross-tabulations and multivariable logistic regression analyses were used to evaluate comorbidity between current DSM-5 CUD, substance use and DSM-5 SUD. Current DSM-5 CUD is associated with greater lifetime use of all examined drug classes, and previous 12-month use of several newer-class illicit and prescription stimulant-based substances (all p< 0.05). Current DSM-5 CUD was similarly associated with increased incidence of a range of DSM-5 SUDs and was independently associated with concurrently reporting current DSM-5; sedative (Adjusted OR= 5.1, 95%CI 2.9-9.0), cocaine (AOR= 9.3, 95%CI 5.6-15.5), stimulant (AOR= 4.3, 95%CI 2.3-7.9), club drug (AOR= 16.1, 95%CI 6.3-40.8), opioid (AOR= 4.6, 95%CI 3.0-6.8) and alcohol-use disorder (AOR= 3.0, 95%CI 2.5-3.7); but not heroin or 'other' drug use disorder (both p>0.05). High comorbidity exists between DSM-5 CUD and many specific DSM-5 SUDs. Newer-class illicit and prescription stimulant-based drug use disorders are overrepresented among those with DSM-5 CUD. These findings underscore the need for tailored treatment programs for those presenting with DSM-5 CUD, and for greater treatment specification where poly-drug use is evident.

Background Adults with substance use disorders (SUDs) report higher rates of child abuse than adults without SUDs. Prior work suggests this abuse is associated with higher rates of psychosis, posttraumatic stress disorder, physical health problems, alcohol dependence, and cannabis dependence among substance users. Little is known about other problems associated with child abuse experienced by substance users. We hypothesized among adults with SUDs, child abuse would be associated with elevated rates of all Diagnostic and Statistical Manual (DSM-IV-TR) psychiatric disorders, substance dependencies, and comorbidities assessed. Method We assessed 280 inpatients in substance use treatment with the Structured Clinical Interview for the DSM-IV-TR, the Diagnostic Instrument for Personality Disorders, and Childhood Trauma Questionnaire (CTQ). We used chi-square and regression analyses to establish whether rates of psychiatric disorders, substance dependencies, and comorbidities differed as a function of child abuse. Results Consistent with our hypotheses, higher scores on the CTQ were associated with elevated rates of psychiatric disorders (mood disorders, anxiety disorders, psychotic symptoms, and personality disorders) and substance dependencies (alcohol dependence and cocaine dependence). Moreover, higher rates of all comorbidity patterns (e.g. comorbid alcohol dependence and anxiety) were observed among individuals who reported experiencing child abuse. Across all substance dependencies examined, individuals who had been abused had significantly higher rates of all psychiatric disorders assessed. Conclusions Individuals with substance use disorders who have been abused have particularly elevated rates of psychiatric and substance use disorders as a function of their abuse experiences. These findings have important treatment implications for individuals in residential substance use treatment settings. PMID:24976457
Mental health disorders among homeless, substance-dependent men who have sex with men.
Fletcher, Jesse B; Reback, Cathy J
2017-07-01
Homelessness is associated with increased prevalence of mental health disorders, substance use disorders and mental health/substance use disorder comorbidity in the United States of America. Gay, bisexual and other men who have sex with men (MSM) living in the United States are at increased risk for homelessness, and have also evidenced elevated mental health and substance use disorder prevalence relative to their non-MSM male counterparts. Secondary analysis of data from a randomised controlled trial estimating the diagnostic prevalence of substance use/mental health disorder comorbidity among a sample of homeless, substance-dependent MSM (DSM-IV verified; n = 131). The most prevalent substance use/mental health disorder comorbidities were stimulant dependence comorbid with at least one depressive disorder (28%), alcohol dependence comorbid with at least one depressive disorder (26%) and stimulant dependence comorbid with antisocial personality disorder (25%). Diagnostic depression and antisocial personality disorder both demonstrated high rates of prevalence among homeless, substance-dependent (particularly stimulant and alcohol dependent) MSM.

Nicotine produces core symptoms of substance dependence (craving and withdrawal) without any psychotic symptoms. The psychopharmacological structure of craving is hypothesized to be constituted by three components: the primary reinforcing property of a substance, the secondary reinforcing property of that substance (conditioned aspects of the environment, such as contextual or specific cues associated with substance taking), and the negative affective motivational property during withdrawal (i.e. the desire to avoid the dysphoric withdrawal symptoms elicits craving). Among the three components, the primary reinforcing property of a substance forms the most fundamental factor for establishing substance dependence. Sensitization or reverse tolerance observed in locomotor activity of animals, which had been believed to be a methamphetamine psychosis model, is demonstrated to reflect the establishment of conditioned reinforcement. Finally, non-substance-related addiction such as gambling, internet, and sex is discussed. From the aspect of the above hypothetical psychopharmacological structure of craving, the most significant difference between substance dependence and non-substance-related addiction is that the primary reinforcing property of non-substance reward is relatively intangible in comparison with that of a substance of abuse.

The Problem Oriented Screening Instrument for Teenagers (POSIT) substance use/abuse subscale has been validated with high school students, adolescents with criminal justice involvement, and adolescent substance use treatment samples using the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III-R and DSM-IV. This study examines the concurrent validity of the POSIT's standard 17-item substance use/abuse subscale and a revised, shorter 11-item version using DSM-5 substance use disorder diagnoses. Adolescents (N = 525; 93% African American, 55% female) 12-17 years of age awaiting primary care appointments at a Federally Qualified Health Center in Baltimore, Maryland completed the 17-item POSIT substance use/abuse subscale and items from a modified World Mental Health Composite International Diagnostic Interview corresponding to DSM-5 alcohol use disorder (AUD) and cannabis use disorder (CUD). Receiver operating characteristic curves, sensitivities, and specificities were examined with DSM-5 AUD, CUD, and a diagnosis of either or both disorders for the standard and revised subscales using risk cutoffs of either 1 or 2 POSIT "yes" responses. For the 17-item subscale, sensitivities were generally high using either cutoff (range: 0.79-1.00), although a cutoff of 1 was superior (sensitivities were 1.00 for AUD, CUD, and for either disorder). Specificities were also high using either cutoff (range: 0.81-0.95) but were higher using a cutoff of 2. For the 11-item subscale, a cutoff of 1 yielded higher sensitivities than a cutoff of 2 (ranges for 1 and 2: 0.96-1.00 and 0.79-0.86, respectively). Specificities for this subscale were higher using a cutoff of 2 (ranges for 1 and 2: 0.82-0.89 and 0.89-0.96, respectively). Findings suggest that the POSIT's substance use/abuse subscale is a potentially useful tool for screening adolescents in primary care for AUD or CUD using a cutoff of 1 or 2. The briefer, revised subscale may be preferable to the standard subscale in busy pediatric practices.
Moderate- vs high-dose methadone in the treatment of opioid dependence: a randomized trial.

Methadone hydrochloride treatment is the most common pharmacological intervention for opioid dependence, and recent interest has focused on expanding methadone treatment availability beyond traditional specially licensed clinics. However, despite recommendations regarding effective dosing of methadone, controlled clinical trials of higher-dose methadone have not been conducted. To compare the relative clinical efficacy of moderate- vs high-dose methadone in the treatment of opioid dependence. A 40-week randomized, double-blind clinical trial starting in June 1992 and ending in October 1995. Outpatient substance abuse treatment research clinic at the Johns Hopkins University Bayview Campus, Baltimore, Md. One hundred ninety-two eligible clinic patients. Daily oral methadone hydrochloride in the dose range of 40 to 50 mg (n = 97) or 80 to 100 mg (n = 95), with concurrent substance abuse counseling. Opioid-positive urinalysis results and retention in treatment. By intent-to-treat analysis through week 30 patients in the high-dose group had significantly lower rates of opioid-positive urine samples compared with patients in the moderate-dose group (53.0% [95% confidence interval [CI], 46.9%-59.2%] vs 61.9% [95% CI, 55.9%-68.0%]; P = .047. These differences persisted during withdrawal from methadone. Through day 210 no significant difference was evident between dose groups in treatment retention (high-dose group mean retention, 159 days; moderate-dose group mean retention, 157 days). Nineteen (33%) of 57 patients in the high-dose group and 11 (20%) of 54 patients in the moderate-dose group completed detoxification. Both moderate- and high-dose methadone treatment resulted in decreased illicit opioid use during methadone maintenance and detoxification. The high-dose group had significantly greater decreases in illicit opioid use.

Neuropeptide substance P (SP) is produced and released by a subset of peripheral sensory neurons that respond to tissue damage (nociceptors). SP exerts excitatory effects in the central nervous system, but peripheral SP actions are still poorly understood; therefore, here, we aimed at investigating these peripheral mechanisms. SP acutely inhibited T-type voltage-gated Ca(2+) channels in nociceptors. The effect was mediated by neurokinin 1 (NK1) receptor-induced stimulation of intracellular release of reactive oxygen species (ROS), as it can be prevented or reversed by the reducing agent dithiothreitol and mimicked by exogenous or endogenous ROS. This redox-mediated T-type Ca(2+) channel inhibition operated through the modulation of CaV3.2 channel sensitivity to ambient zinc, as it can be prevented or reversed by zinc chelation and mimicked by exogenous zinc. Elimination of the zinc-binding site in CaV3.2 rendered the channel insensitive to SP-mediated inhibition. Importantly, peripherally applied SP significantly reduced bradykinin-induced nociception in rats in vivo; knock-down of CaV3.2 significantly reduced this anti-nociceptive effect. This atypical signaling cascade shared the initial steps with the SP-mediated augmentation of M-type K(+) channels described earlier. Our study established a mechanism underlying the peripheral anti-nociceptive effect of SP whereby this neuropeptide produces ROS-dependent inhibition of pro-algesic T-type Ca(2+) current and concurrent enhancement of anti-algesic M-type K(+) current. These findings will lead to a better understanding of mechanisms of endogenous analgesia. SP modulates T-type channel activity in nociceptors by a redox-dependent tuning of channel sensitivity to zinc; this novel modulatory pathway contributes to the peripheral anti-nociceptive effect of SP.

The American Society for Pain Management Nursing (ASPMN) has updated its position statement on managing pain in patients with substance use disorders. This position statement is endorsed by the International Nurses Society on Addictions (IntNSA) and includes clinical practice recommendations based on current evidence. It is the position of ASPMN and IntNSA that every patient with pain, including those with substance use disorders, has the right to be treated with dignity, respect, and high-quality pain assessment and management. Failure to identify and treat the concurrent conditions of pain and substance use disorders will compromise the ability to treat either condition effectively. Barriers to caring for these patients include stigmatization, misconceptions, and limited access to providers skilled in these two categories of disorders. Topics addressed in this position statement include the scope of substance use and related disorders, conceptual models of addiction, ethical considerations, addiction risk stratification, and clinical recommendations.

This study describes the initiation and maintenance of illicit drug use, risky behaviors, and the substance use treatment experiences of women in Georgia. Qualitative interviews with 55 drug-using women (mean age 36 years; SD = 9.52), were conducted during April-September 2011. Participants presented diverse histories of drug use initiation and substance use, risky behaviors, and drug treatment participation. All participants reported concurrent use of different substances, including home-produced injection preparations. Women described their experiences of both the positive and negative effects (physical and psychological) that they attributed to their use of drugs. Findings enrich our understanding of the environment in which substance use is initiated and maintained in a female population in Georgia, and illustrate the importance of culture and the role of social factors in the development of injection drug use. Results can provide direction for tailoring the development of interventions for substance use disorders, public policy discussions regarding the treatment of women who use drugs, and future research on substance use among women in Georgia and other post-Soviet nations.

This study examined barriers to employability among women meeting criteria for a substance dependence disorder who were identified by routine screening conducted in welfare offices. The characteristics of these women were compared to other women on welfare who did not have a substance use disorder. A sample of 214 substance dependent women on federal welfare were recruited to participate in a substance use disorders welfare demonstration project. An additional 69 nonsubstance-affected women on welfare served as a comparison sample. All participants were assessed in welfare settings through a standardized battery of measures. Substance dependent women reported moderate to severe substance use problems. They also reported significantly higher rates than the women with no substance use disorder of other barriers such as domestic violence, mental health problems, legal problems, child welfare investigations and fewer job skills. Findings raise questions about the likely effectiveness of existing welfare reform services in addressing the needs of substance dependent women.

There is growing evidence that anhedonia is a commonly experienced symptom among substance-using populations. This systematic review synthesises findings across a range of substances to address questions regarding the time course of anhedonia, how anhedonia relates to other symptoms of substance dependence and whether it is similarly prevalent across all addictive drugs. A literature search was conducted on PubMed, PsycINFO and MEDLINE, yielding 32 studies that used self-report measures of anhedonia among participants with a history of a substance abuse, dependence or long-term daily use of addictive substances. Findings from these studies indicate that anhedonia (1) is elevated in samples dependent on a range of substances; (2) typically appears as a consequence of substance abuse or dependence, and diminishes with abstinence; and (3) predicts increased drug cravings and the likelihood of relapse in those attempting abstinence. The common experience of anhedonia in substance-dependent populations, and its relationship to relapse, emphasises the importance of developing therapeutic interventions that specifically target anhedonia in the treatment of all substance use disorders.
Chronic pain and opioid misuse: a review of reviews.

The crisis of prescription opioid (PO) related harms has focused attention toward identifying and treating high-risk populations. This review aims to synthesize systematic reviews on the epidemiology and clinical management of comorbid chronic pain and PO or other substance misuse. A systematic database search was conducted to identify systematic reviews published between 2000 and 2016. Eligible studies were systematic reviews related to chronic non-cancer pain and PO or other substance misuse. Evidence from the included reviews was synthesized according to epidemiology and clinical management themes. Of 1908 identified articles, 18 systematic reviews were eligible for final inclusion. Two meta-analyses estimated the prevalence of chronic non-cancer pain in individuals using POs non-medically to be approximately 48% to 60%, which is substantially higher than the prevalence of chronic non-cancer pain in general population samples (11% to 19%). Five systematic reviews estimated the rates of PO or other opioid use in chronic pain populations with substantial variation in results (0.05% to 81%), likely due to widely varying definitions of dependence, substance use disorder, misuse, addiction, and abuse. Several clinical assessment and treatment approaches were identified, including: standardized assessment instruments; urine drug testing; medication counts; prescription drug monitoring programs; blood level monitoring; treatment agreements; opioid selection; dosing and dispensing strategies; and opioid agonist treatment. However, the reviews commonly noted serious limitations, inconsistencies, and imprecision of studies, and a lack of evidence on effectiveness or clinical utility for the majority of these strategies. Overall, current systematic reviews have found a lack of high-quality evidence or consistent findings on the prevalence, risk factors, and optimal clinical assessment and treatment approaches related to concurrent chronic pain and substance misuse. Given the role of systematic reviews in guiding evidence-based medicine and health policy, there is an urgent need for high-quality primary research to guide future systematic reviews to address the escalating epidemic of harms related to chronic pain and substance misuse.

Cigarette smoking is common in adolescents with attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD). However, little is known about the relationship between cigarette and cannabis use trajectories in the context of treatment for both ADHD and SUD. To address this research gap, we report collateral analyses from a 16-week randomized, controlled trial (n=303) of osmotic-release methylphenidate (OROS-MPH) in adolescents with ADHD concurrently receiving cognitive behavioral therapy (CBT) targeting non-nicotine SUD. Participants completed cigarette and cannabis use self-report at baseline and throughout treatment. Analyses were performed to explore the relationships between cigarette smoking, cannabis use, and other factors, such as medication treatment assignment (OROS-MPH versus placebo). Baseline (pre-treatment) cigarette smoking was positively correlated with cannabis use. Negligible decline in cigarette smoking during treatment for non-nicotine SUD was observed in both medication groups. Regular cigarette and cannabis users at baseline who reduced their cannabis use by >50% also reduced cigarette smoking (from 10.8±1.1 to 6.2±1.1 cigarettes per day). Findings highlight the challenging nature of concurrent cannabis and cigarette use in adolescents with ADHD, but demonstrate that changes in use of these substances during treatment may occur in parallel.

Inhibiting responses is a challenge, where the outcome (partly) depends on the situational context. In everyday situations, response inhibition performance might be altered when irrelevant input is presented simultaneously with the information relevant for response inhibition. More specifically, irrelevant concurrent information may either brace or interfere with response-relevant information, depending on whether these inputs are redundant or conflicting. The aim of this study is to investigate neurophysiological mechanisms and the network underlying such modulations using EEG beamforming as method. The results show that in comparison to a baseline condition without concurrent information, response inhibition performance can be aggravated or facilitated by manipulating the extent of conflict via concurrent input. This depends on whether the requirement for cognitive control is high, as in conflicting trials, or whether it is low, as in redundant trials. In line with this, the total theta frequency power decreases in a right hemispheric orbitofrontal response inhibition network including the SFG, MFG, and SMA, when concurrent redundant information facilitates response inhibition processes. Vice versa, theta activity in a left-hemispheric response inhibition network (i.e., SFG, MFG, and IFG) increases, when conflicting concurrent information compromises response inhibition processes. We conclude that concurrent information bi-directionally shifts response inhibition performance and modulates the network architecture underlying theta oscillations which are signaling different levels of the need for cognitive control.

Attention-deficit hyperactivity disorder is a risk factor of smoking and alcohol drinking in adolescence. Since attention-deficit hyperactivity disorder and smoking and alcohol drinking in adolescence are predictors for the development of substance use disorders in adulthood, it is important to understand the nature of these associations. The aim of the authors was to investigate associations between attention-deficit hyperactivity disorder symptoms and the joint use of alcohol and nicotine among 9th graders. A representative sample of 944 pupils attending state-run secondary schools in Budapest were recruited. Generalized Linear Mixed Model and logistic regression analyses have been conducted. The prevalence was 29.6% and 41.4% for current smoking and current alcohol drinking, respectively. The prevalence of their concurrent-use was 21.7%. Alcohol drinking and smoking showed a significant positive association with the total scores of Attention-Deficit Hyperactivity Disorder Scale and with the Attention Deficit and Hyperactivity/Impulsivity subscales. The findings highlight the potential importance of attention-deficit hyperactivity disorder in the development of the joint use of these substances.

The objectives of this study were to examine the association between individual and partnership characteristics with condom use, sexual concurrency, and discordance in monogamy perceptions among out-of-treatment, young adult, drug-involved couples to gain a better understanding of how discordance in monogamy beliefs may influence HIV/sexually transmitted infection risk. Data were collected from 94 predominantly black heavy alcohol and/or drug users (AOD) and their steady partners recruited through street outreach in Durham, North Carolina, and a methadone clinic in Raleigh, North Carolina. One third was wrong about partners' monogamy intentions. Greater lifetime number of substances, longer relationship duration, and at least weekly relationship conflict were associated with inconsistent condom use, and discordant monogamy beliefs were associated with consistent condom use. Many individuals misperceive their partners' monogamy intentions, although this misperception may be reflective of greater HIV/sexually transmitted infection protection. Interventions for couples should focus on strategies appropriate for committed long-term relationships, including increasing awareness of partner risk behavior, negotiating safety, and conflict resolution skills.

Introduction Research has shown that eating disorder (ED) patients who abuse substances demonstrate worse ED symptomatology and poorer outcomes than those with EDs alone, including increased general medical complications and psychopathology, longer recovery times, poorer functional outcomes and higher relapse rates. This article provides a broad overview of the prevalence, aetiology, assessment and management of co-morbid EDs and substance use disorders (SUDs). Review The co-occurrence of EDs and SUDs is high. The functional relationship between EDs and SUDs vary within and across ED subtypes, depends on the class of substance, and needs to be carefully assessed for each patient. Substances such as caffeine, tobacco, insulin, thyroid medications, stimulants or over the counter medications (laxatives, diuretics) may be used to aid weight loss and/or provide energy, and alcohol or psychoactive substances could be used for emotional regulation or as part of a pattern of impulsive behaviour. A key message conveyed in the current literature is the importance of screening and assessment for co-morbid SUDs and EDs in patients presenting with either disorder. There is a paucity of treatment studies on the management of co-occurring EDs and SUDs. Overall, the literature indicates that the ED and SUD should be addressed simultaneously using a multi-disciplinary approach. The need for medical stabilization, hospitalization or inpatient treatment needs to be assessed based on general medical and psychiatric considerations. Common features across therapeutic interventions include psycho-education about the aetiological commonalities, risks and sequelae of concurrent ED behaviours and substance abuse, dietary education and planning, cognitive challenging of eating disordered attitudes and beliefs, building of skills and coping mechanisms, addressing obstacles to improvement and the prevention of relapse. Emphasis should be placed on building a collaborative therapeutic relationship and avoiding power struggles. Cognitive behavioural therapy has been frequently used in the treatment of co-morbid EDs and SUDs, however there are no randomized controlled trials. More recently evidence has been found for the efficacy of dialectical behavioural therapy in reducing both ED and substance use behaviours. Conclusion Future research would benefit from a meta-analysis of the current research in order to better understand the relationships between these two commonly co-occurring disorders. PMID:24200300

Substance abuse treatment response in a Latino sample: the influence of family conflict.
Fish, Jessica N; Maier, Candice A; Priest, Jacob B
2015-02-01
Latino Americans report underutilization of treatment and poor treatment response for substance use and abuse compared to other racial/ethnic groups; thus, it is important to assess factors that contribute to these disparities. The current study objective was to assess the influence of family conflict on substance abuse treatment response in a sample of Latino Americans using two different yet complementary analyses. First, ordinary least squares regression was used to assess the association between overall family conflict and pre- and post-treatment substance use. Second, repeated measures latent class analysis was used to identify groups based on family member conflict and timing of conflict during treatment. Findings indicated that family conflict contributed unique variance to concurrent substance use; however pre-treatment family conflict was not related to post-treatment outcomes. Results also identified three distinct family conflict groups: no/low conflict, pre-treatment conflict, and post-treatment conflict who differed in pre- and post-treatment substance use. Post hoc investigation revealed that those who experienced pre-treatment conflict but low post-treatment conflict showed the greatest decrease in substance use. Findings highlight the importance of considering family conflict during all stages of treatment for Latino American substance users. Copyright © 2015 Elsevier Inc. All rights reserved.

To investigate the age of onset of phobic disorders in relation to later development of substance dependence in a sample of adolescent psychiatric patients. Clinical sample of 238 adolescents (age 12-17) admitted to psychiatric inpatient hospitalization between April 2001 and July 2003. Psychiatric diagnoses and onset ages obtained from the schedule for affective disorders and schizophrenia for school aged children-present and lifetime (K-SADS-PL). Logistic regression analyses revealed that adolescents with phobic disorders had a 4.9-fold risk for comorbid substance dependence compared to those without phobia. The mean onset age was 11.4 and 14.4 years for phobias and comorbid substance dependence, respectively. Boys (13.7 years) had a statistically significantly lower onset age for substance dependence than girls (15.4 years). Over one-half of the adolescents with phobic disorders had developed substance dependence within three years after the onset of phobia. We found that phobias might influence the development of secondary substance dependence within a few years from the onset of phobia already in adolescence.

Deficits in sustained attention and impulsivity have previously been demonstrated in preschoolers prenatally exposed to cocaine. We assessed an additional component of attention, selective attention, in a large, poly-substance cocaine-exposed cohort of 4 year olds and their at-risk comparison group. Employing postpartum maternal report and biological assay, we assigned children to overlapping exposed and complementary control groups for maternal use of cocaine, alcohol, marijuana, and cigarettes. Maternal pregnancy use of cocaine and use of cigarettes were both associated with increased commission errors, indicative of inferior selective attention. Severity of maternal use of marijuana during pregnancy was positively correlated with omission errors, suggesting impaired sustained attention. Substance exposure effects were independent of maternal postpartum psychological distress, birth mother cognitive functioning, current caregiver functioning, other substance exposures and child concurrent verbal IQ.

Although mental disorders have been shown to predict subsequent substance disorders, it is not known whether substance disorders could be cost-effectively prevented by large-scale interventions aimed at prior mental disorders. Although experimental intervention is the only way to resolve this uncertainty, a logically prior question is whether the associations of mental disorders with subsequent substance disorders are strong enough to justify mounting such an intervention. We investigated this question in this study using simulations to estimate the number of substance disorders that might be prevented under several hypothetical intervention scenarios focused on mental disorders. Data came from the National Comorbidity Survey Replication (NCS-R), a nationally representative US household survey that retrospectively assessed lifetime history and age of onset of DSM-IV mental and substance disorders. Survival analysis using retrospective age-of-onset reports was used to estimate associations of mental disorders with subsequent substance dependence. Simulations based on the models estimated effect sizes in several hypothetical intervention scenarios. Although successful intervention aimed at mental disorders might prevent some proportion of substance dependence, the number of cases of mental disorder that would have to be treated to prevent a single case of substance dependence is estimated to be so high that this would not be a cost-effective way to prevent substance dependence (in the range 76-177 for anxiety-mood disorders and 40-47 for externalizing disorders). Treatment of prior mental disorders would not be a cost-effective way to prevent substance dependence. However, prevention of substance dependence might be considered an important secondary outcome of interventions for early-onset mental disorders.

Purpose To assess changes in inmates’ misuse of substances from pre- to post-incarceration. Methods In Study 1, professionals (n = 162) and laypersons (n = 50) predicted how jail inmates’ substance misuse would change from pre-incarceration to post-release. In Study 2, a longitudinal study of 305 jail inmates, we examined actual changes in substance use and dependence from pre-incarceration to the first year post-incarceration, as well as whether changes varied as a function of demographic, criminal justice, treatment, and personality factors. Results Professionals and laypersons predicted little change in substance misuse whereas, in fact, inmates’ frequency of substance use and dependence decreased substantially from pre-incarceration to post-release. Sharper decreases were observed for inmates who were female, younger, more educated, serving longer sentences, enrolled in substance abuse treatment, high in shame-proneness, and low in criminogenic thinking. Race, first time incarceration, transfer to other correctional facilities, mandated community supervision (probation), and guilt-proneness did not predict changes in substance use or dependence. Conclusions Although substance misuse decreased, this remains a population high in need of substance abuse treatment both upon arrest and at one year post-incarceration; 60% of former inmates met at least one DSM-IV criterion for substance dependence at one year post-release.

Substance use disorders are diagnosed as a manifestation of inappropriate behavioral allocation toward abused drugs and away from other behaviors maintained by more adaptive nondrug reinforcers (e.g., money and social relationships). Substance use disorder treatment goals include not only decreasing drug-maintained behavior but also promoting behavioral reallocation toward these socially adaptive alternative reinforcers. Preclinical drug self-administration procedures that offer concurrent access to both drug and nondrug reinforcers provide a translationally relevant dependent measure of behavioral allocation that may be useful for candidate medication evaluation. In contrast to other abused drugs, such as heroin or cocaine, preclinical methamphetamine versus food choice procedures have been a more recent development. We hypothesize that preclinical to clinical translatability would be improved by the evaluation of repeated pharmacological treatment effects on methamphetamine self-administration under a methamphetamine versus food choice procedure. In support of this hypothesis, a literature review suggests strong concordance between preclinical pharmacological treatment effects on methamphetamine versus food choice in nonhuman primates and clinical medication treatment effects on methamphetamine self-administration in human laboratory studies or methamphetamine abuse metrics in clinical trials. In conclusion, this literature suggests preclinical methamphetamine versus food choice procedures may be useful in developing innovative pharmacotherapies for methamphetamine use disorder. © 2016 New York Academy of Sciences.

The mu1 opioid receptor gene, OPRM1, has long been a high-priority candidate for human genetic studies of addiction. Because of its potential functional significance, the non-synonymous variant rs1799971 (A118G, Asn40Asp) in OPRM1 has been extensively studied, yet its role in addiction has remained unclear, with conflicting association findings. To resolve the question of what effect, if any, rs1799971 has on substance dependence risk, we conducted collaborative meta-analyses of 25 datasets with over 28,000 European-ancestry subjects. We investigated non-specific risk for "general" substance dependence, comparing cases dependent on any substance to controls who were non-dependent on all assessed substances. We also examined five specific substance dependence diagnoses: DSM-IV alcohol, opioid, cannabis, and cocaine dependence, and nicotine dependence defined by the proxy of heavy/light smoking (cigarettes-per-day >20 vs. ≤ 10). The G allele showed a modest protective effect on general substance dependence (OR = 0.90, 95% C.I. [0.83-0.97], p value = 0.0095, N = 16,908). We observed similar effects for each individual substance, although these were not statistically significant, likely because of reduced sample sizes. We conclude that rs1799971 contributes to mechanisms of addiction liability that are shared across different addictive substances. This project highlights the benefits of examining addictive behaviors collectively and the power of collaborative data sharing and meta-analyses.

Commitment to change is an innovative potential mediator or mechanism of behavior change that has not been examined in adolescents with substance use disorders (SUD). The Adolescent Substance Abuse Goal Commitment (ASAGC) questionnaire is a 16-item measure developed to assess an individual's commitment to his/her stated treatment goal. The objectives of this study are to explore the research and clinical utility of the commitment construct as measured by the ASAGC. During sessions 3 and 9 of a 10-week SUD treatment, therapists completed the ASAGC for 170 13-18 year-old adolescents. An exploratory factor analysis was conducted on the ATAGC items. Concurrent validity with related constructs, self-efficacy and motivation for change, was examined as well. At both sessions, the factor analysis resulted in two scales--Commitment to Recovery and Commitment to Harm Reduction. The ASAGC scales were found to demonstrate a high level of internal consistency (alpha coefficients ranged from .92 to .96 over time). In contrast to the Commitment to Harm Reduction scale, the Commitment to Recovery scale consistently correlated with scales from the Situational Confidence Questionnaire assessing self-efficacy, evidencing concurrent validity. Similarly, the Commitment to Recovery scale was related to the Problem Recognition Questionnaire, providing further evidence of the validity of the ASAGC. The ASAGC is a reliable and valid clinical research instrument for the assessment of adolescents' commitment to their substance abuse treatment goal. Clinical researchers may take advantage of the clinical utility of the ASAGC including its ability to differentiate between commitment to abstinence versus commitment to harm reduction.

The present research addressed the following important question in pediatric medicine: Can participation in a new family-centered preventive intervention, the Strong African American Families-Teen (SAAF-T) program, deter conduct problems, substance use, substance use problems, and depressive symptoms among rural black adolescents across 22 months? Data were collected from 502 black families in rural Georgia, assigned randomly to SAAF-T or an attention control condition. The prevention condition consisted of 5 consecutive meetings at community facilities with separate, concurrent sessions for caregivers and adolescents followed by a caregiver-adolescent session in which families practiced skills they learned in the separate sessions. Adolescents self-reported conduct problem behaviors, substance use, substance use problems, and depressive symptoms at ages 16 years (pretest) and 17 years 10 months (long-term assessment). Adolescents who participated in SAAF-T evinced lower increases in conduct problem behavior, substance use, substance use problems, and depressive symptom frequencies than did adolescents in the attention control condition across the 22 months between pretest and long-term assessment. This is the first study to demonstrate efficacy in a prevention program designed to deter conduct problems, substance use, substance use problems, and depressive symptoms among rural black adolescents. Because SAAF-T is a manualized, structured program, it can be easily disseminated to public health agencies, schools, churches, boys' and girls' clubs, and other community organizations.

Large-scale treatment studies suggest that effective depression treatment and reduced depression are associated with improved substance use outcomes. Yet information is limited regarding the longitudinal association between depressive symptoms and problematic substance use and its predictors, particularly in real-world practice settings. Using latent growth modeling, we examined the (a) longitudinal association between depressive symptoms and problematic substance use, (b) impact of depressive symptoms on problematic substance use, (c) impact of problematic substance use on depressive symptoms, and (d) role of co-occurring symptoms on depression and problematic substance use. Participants were part of the Youth Partners in Care study, an effectiveness trial evaluating a quality improvement intervention for youth depression through primary care. This ethnically diverse sample included youths aged 13 to 21 years screening positive for depression from 5 health care organizations. Participants were followed 4 times over an 18-month period and assessed for both depressive symptoms and problematic substance use. Both depressive symptoms and problematic substance use declined over time. Higher baseline depressive symptoms predicted a slower decline in problematic substance use, but baseline problematic substance use did not predict changes in depressive symptoms. These prospective associations remained robust controlling for co-occurring symptoms. Results support prior large-scale depression studies indicating depression burden negatively impacts substance use outcome and extends these findings to real-world practice settings. Findings underscore the importance of addressing depression severity in youth with concurrent substance use problems, even in the context of comorbid symptoms of anxiety, delinquency, and aggression.

Continuous morphine consumption contributes to the development of cognitive disorders. This work investigates the impacts of different types of exercise on learning and memory in morphine-dependent rats. Forty morphine-dependent rats were randomly divided into five groups: sedentary-dependent (Sed-D), endurance exercise-dependent (En-D), strength exercise-dependent (St-D), and combined (concurrent) exercise-dependent (Co-D). Healthy rats were used as controls (Con). After 10weeks of regular exercise (endurance, strength, and concurrent; each five days per week), spatial and aversive learning and memory were assessed using the Morris water maze and shuttle box tests. The results showed that morphine addiction contributes to deficits in spatial learning and memory. Furthermore, each form of exercise training restored spatial learning and memory performance in morphine-dependent rats to levels similar to those of healthy controls. Aversive learning and memory during the acquisition phase were not affected by morphine addiction or exercise, but were significantly decreased by morphine dependence. Only concurrent training returned the time spent in the dark compartment in the shuttle box test to control levels. These findings show that different types of exercise exert similar effects on spatial learning and memory, but show distinct effects on aversive learning and memory. Further, morphine dependence-induced deficits in cognitive function were blocked by exercise. Therefore, different exercise regimens may represent practical treatment methods for cognitive and behavioral impairments associated with morphine-related disease. Copyright © 2016 Elsevier Inc.

In this study, the prevalence of psychoactive substance use and dependence was estimated among students at a Spanish university, together with associated factors, polyconsumption, and comorbidity with depression, using a 554-member sample stratified by sex, degree year, and discipline. 86.5% had consumed some potentially addictive psychoactive substance in the past month, and 10.5% satisfied DSM-IV criteria for dependence on nicotine, alcohol, caffeine, or cannabis. Polyconsumers (90.4%) consumed an average 3.2 different substances. Current depression implied increased likelihood of having consumed tobacco or psychoactive pharmaceutical drugs in the past month, and DSM-IV symptoms of major depressive episode were shown by 8.6% of 58 substance-dependent participants, 8.7% of 540 past-month legal substance consumers, and 12.1% of 140 past-month illegal substance consumers.

The American Society for Pain Management Nursing (ASPMN) has updated its position statement on managing pain in patients with substance use disorders. This position statement is endorsed by the International Nurses Society on Addictions (IntNSA) and includes clinical practice recommendations based on current evidence. It is the position of ASPMN and IntNSA that every patient with pain, including those with substance use disorders, has the right to be treated with dignity, respect, and high-quality pain assessment and management. Failure to identify and treat the concurrent conditions of pain and substance use disorders will compromise the ability to treat either condition effectively. Barriers to caring for these patients include stigmatization, misconceptions, and limited access to providers skilled in these two categories of disorders. Topics addressed in this position statement include the scope of substance use and related disorders, conceptual models of addiction, ethical considerations, addiction risk stratification, and clinical recommendations.

We assessed whether a meaningful set of latent risk profiles could be identified in an inner-city population through individual and network characteristics of substance use, sexual behaviors, and mental health status. Data came from 600 participants in Social Network Study III, conducted in 2009 in Winnipeg, Manitoba, Canada. We used latent class analysis (LCA) to identify risk profiles and, with covariates, to identify predictors of class. A 4-class model of risk profiles fit the data best: (1) solitary users reported polydrug use at the individual level, but low probabilities of substance use or concurrent sexual partners with network members; (2) social-all-substance users reported polydrug use at the individual and network levels; (3) social-noninjection drug users reported less likelihood of injection drug and solvent use; (4) low-risk users reported low probabilities across substances. Unstable housing, preadolescent substance use, age, and hepatitis C status predicted risk profiles. Incorporation of social network variables into LCA can distinguish important subgroups with varying patterns of risk behaviors that can lead to sexually transmitted and bloodborne infections.

Anxiety-related characteristics, including anxiety sensitivity and trait anxiety, are elevated in individuals with alcohol and nicotine dependence and associated with greater difficulties with quitting smoking. However, little is known about how anxiety-related characteristics are related to smoking cessation outcomes in alcohol-dependent smokers. The present study, part of a larger smoking cessation clinical trial, examined associations between anxiety sensitivity, trait anxiety, nicotine withdrawal symptoms, smoking urges, and smoking cessation outcomes in a sample of 83 alcohol-dependent smokers. Participants were enrolled in concurrent alcohol and tobacco treatment as part of a substance-abuse intensive outpatient program. Smoking cessation treatment was administered in a 3-week cognitive-behavioral format that included 8 weeks of open-label nicotine patch treatment. Information on nicotine withdrawal, smoking urges, and CO-confirmed smoking consumption rates was collected at baseline, quit date, end of behavioral treatment, and at a 1-month follow-up. Higher levels of anxiety sensitivity were associated with more smoking urges due to anticipation of negative affect relief at quit date. Higher levels of trait anxiety were associated with more smoking urges due to positive reinforcement and anticipation of relief of negative affect at quit date, as well as more severe nicotine withdrawal symptoms at the end of treatment. Levels of anxiety sensitivity and trait anxiety were not associated with Cox regression survival times to relapse. These results indicate that for alcohol-dependent smokers, levels of anxiety sensitivity and trait anxiety are important to consider in the assessment and treatment of nicotine dependence.
Social dimensions of adolescent substance use.

The aim of this study was to explore in detail the relationship between various social aspects of young people's lives and substance use and differences in the degree of influence exerted by the different social factors as a function of age. Design, setting, participants. The study was a survey of pupils aged 11-16 in a stratified sample of five English schools. Data from 4516 participants were obtained in relation to their cigarette, alcohol and illicit drug use and their contact with the police, perceived academic achievements and future expectations, religious beliefs, family structure, the importance of family versus peer opinions and suspension from school. Cumulative, age-specific preferences of substance misuse were compared. Logistic regression was used to rank the various risk factors. Substantial differences were found between substance users and non-users and the various risk factors being examined. For example, of those who had only been in trouble with the police, 18.8% used illegal drugs compared with 1.6% of those who had not had a police contact and who had no other risk factors. Many of these relationships were age-sensitive. For instance, the negative relationship between belief in God and illicit drug use became stronger as age increased (non-believers: y = 8.1886x - 9.16 R(2) = 0.9484; believers: y = 5.1514x - 8.08 R(2) = 0.9247). These results suggest that, within this sample of English adolescents, there was a strong relationship between substance use and the social factors examined. Although there were differences depending upon whether cigarette, alcohol or illicit drug use was being modelled, logistic regression indicated that the social factors could be ranked in the following order of importance: concurrent use of the second and third substances, having been in trouble with the police, perceived poor academic performance and low future academic expectations, a lack of religious belief, coming from a non-intact family, favouring peer over family opinion and having been suspended from school. Many of these relationships were age-sensitive with substance use peaking at age 15. The models and relationships presented in this paper show that a constellation of behaviours are related to adolescent substance use. Also demonstrated is that behaviours cannot be considered in isolation, but need to be examined from an holistic or biopsychosocial standpoint. These relationships are complex and future research should consider not only causality of adolescent substance use, but also of the aetiology of the satellite behaviours.

Introduction and aims To examine differences in the characteristics and histories of male and female dependent heroin users, and in the clinical characteristics associated with multiple substance dependence diagnoses. Design and methods 1513 heroin dependent participants underwent an interview covering substance use and dependence, psychiatric history, child maltreatment, family background, adult violence and criminal history. Family background, demographic and clinical characteristics were analysed by sex. Ordinal regression was used to test for a relationship between number of substance dependence diagnoses and other clinical variables. Results Women were more likely to experience most forms of child maltreatment, to first use heroin with a boyfriend or partner, to experience ongoing adult violence at the hands of a partner, and to have a poorer psychiatric history than men. Males had more prevalent lifetime substance dependence diagnoses and criminal histories and were more likely to meet criteria for ASPD. Predictors of multiple substance dependence diagnoses for both sexes were mental health variables, antisocial behaviour, childhood sexual abuse, victim of adult violence, younger age at first cannabis use and overdose. As the number of dependence diagnoses increased, clinical and behavioural problems increased. Childhood emotional neglect was related to increasing dependence diagnoses for females but not males, whereas PTSD was a significant predictor for males but not females. Discussion and conclusions Mental health problems, other substance dependence, childhood and adult trauma were common in this sample, with sex differences indicating different treatment needs and possible different pathways to heroin dependence for men and women.

Aims This study explored the factor structure of DSM III-R/IV symptoms for substance abuse and dependence across six illicit substance categories in a population-based sample of males. Method DSM III-R/IV drug abuse and dependence symptoms for cannabis, sedatives, stimulants, cocaine, opioids and hallucinogens from 4179 males born 1940-1970 from the population-based Virginia Adult Twin Study of Psychiatric and Substance Use Disorders were analyzed. Confirmatory factor analyses tested specific hypotheses regarding the latent structure of substance misuse for a comprehensive battery of 13 misuse symptoms measured across six illicit substance categories (78 items). Results Among the models fit, the latent structure of substance misuse was best represented by a combination of substance-specific factors and misuse symptom-specific factors. We found no support for a general liability factor to illicit substance misuse. Conclusions Results indicate that liability to misuse illicit substances is drug class specific, with little evidence for a general liability factor. Additionally, unique dimensions capturing propensity toward specific misuse symptoms (e.g., tolerance, withdrawal) across substances were identified. While this finding requires independent replication, the possibility of symptom-specific misuse factors, present in multiple substances, raises the prospect of genetic, neurobiological and behavioral predispositions toward distinct, narrowly defined features of drug abuse and dependence.

2018-01-01
Comorbidity between substance use disorders (SUD) and major depression (MD) is the most common dual pathology in the field of addiction to substances and has prevalence rates ranging between 12% and 80%, which complicates the response to treatment and worsens the prognosis of patients. Differentiating between diagnoses of induced depressive episodes and primary depressive episodes concurrent to substance use is especially relevant for therapeutic management. This article presents the state of the art of the currently available pharmacologic treatments of comorbid depression in patients with SUD, taking into account the safety and risk of abuse of antidepressant drugs. Due to the fact that comorbidity of MD and SUD is frequent and presents greater psychopathological and medical severity, as well as worse social functioning, it is crucial to treat MD and SUD simultaneously using the integrated treatment model and not to treat both conditions separately.

Substance-related and addictive disorders are chronic relapsing conditions that substantially impact public health. Effective treatments for these disorders require addressing substance use/dependence comprehensively as well as other associated comorbidities. Comprehensive addressing of substance use in a medical setting involves screening for substance use, addressing substance use directly with the patient, and formulating an appropriate intervention. For alcohol dependence and opioid dependence, pharmacotherapies are available that are safe and effective when utilized in a comprehensive treatment paradigm, such as medication assisted treatment. In primary care, substance use disorders involving alcohol, illicit opioids, and prescription opioid abuse are common among patients who seek primary care services. Primary care providers report low levels of preparedness and confidence in identifying substance-related and addictive disorders and providing appropriate care and treatment. However, new models of service delivery in primary care for individuals with substance-related and addictive disorders are being developed to promote screening, care and treatment, and relapse prevention. The education and training of primary care providers utilizing approved medications for the treatment of alcohol use disorders and opioid dependence in a primary care setting would have important public health impact and reduce the burden of alcohol abuse and opioid dependence.

Research in adults shows that substance dependent individuals demonstrate attentional bias (AB) for substance-related stimuli. This study investigated the role of AB in adolescents diagnosed with alcohol, cannabis, amphetamine or GHB dependency on entering therapy and six months later, and the role of executive control (EC) as a moderator of the relationship between problem severity and AB. Seventy-eight young substance-dependent (SD) patients (mean age=19.5), and 64 healthy controls (HC; mean age=19.0) were tested. Thirty-eight SD patients took part at 6-month follow-up (FU). AB was indexed by a visual probe task, EC by the attention network task, problem severity by the short alcohol (or drug) use disorder identification test and the severity of dependence questionnaire. SD patients demonstrated an AB for substance stimuli presented for 500 ms and 1250 ms, with the latter related to severity of dependence. There was a nonsignificant tendency indicating that EC was higher in HC than SD participants, but EC did not moderate the relationship between AB and dependency. Substance use, dependency, EC and AB remained unchanged in the 6 month FU period. Young SD patients showed a stronger relatively early as well as maintained AB toward substance cues. A stronger maintained attention was related to higher severity of dependence. Further, there were some indications that EC might play a role in adolescent substance use. The finding that at FU AB and problem severity were not decreased, and EC was not increased underlines the persistent character of addiction. Copyright © 2015 Elsevier Ireland Ltd.

A comparison of analysis methods to estimate contingency strength.
Lloyd, Blair P; Staubitz, Johanna L; Tapp, Jon T
2018-05-09
To date, several data analysis methods have been used to estimate contingency strength, yet few studies have compared these methods directly. To compare the relative precision and sensitivity of four analysis methods (i.e., exhaustive event-based, nonexhaustive event-based, concurrent interval, concurrent+lag interval), we applied all methods to a simulated data set in which several response-dependent and response-independent schedules of reinforcement were programmed. We evaluated the degree to which contingency strength estimates produced from each method (a) corresponded with expected values for response-dependent schedules and (b) showed sensitivity to parametric manipulations of response-independent reinforcement. Results indicated both event-based methods produced contingency strength estimates that aligned with expected values for response-dependent schedules, but differed in sensitivity to response-independent reinforcement. The precision of interval-based methods varied by analysis method (concurrent vs. concurrent+lag) and schedule type (continuous vs. partial), and showed similar sensitivities to response-independent reinforcement. Recommendations and considerations for measuring contingencies are identified. © 2018 Society for the Experimental Analysis of Behavior.

Attention Deficit Hyperactivity Disorder (ADHD) is a risk for substance use disorders. The aim of this study was to investigate the association between adult ADHD symptoms, opioid use disorder, life dysfunction and co-occurring psychiatric symptoms. 1057 heroin dependent patients on opioid substitution treatment participated in the survey. All patients were screened for adult ADHD symptoms using the Adult ADHD Self-Report Scale (ASRS-v1.1). 19.4% of the patients screened positive for concurrent adult ADHD symptoms status and heroin dependence. Education level was lower among patients with ADHD symptoms, but not significant with respect to non-ADHD patients. Patients with greater ADHD symptoms severity were less likely to be employed. A positive association was observed between ADHD symptoms status and psychiatric symptoms. Patients with ADHD symptoms status were more likely to be smokers. Patients on methadone had a higher rate of ADHD symptoms status compared to buprenorphine. Those individuals prescribed psychoactive drugs were more likely to have ADHD symptoms. In conclusion, high rate of ADHD symptoms was found among heroin dependent patients, particularly those affected by the most severe form of addiction. These individuals had higher rates of unemployment, other co-morbid mental health conditions, heavy tobacco smoking. Additional psychopharmacological interventions targeting ADHD symptoms, other than opioid substitution, is a public health need. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.
Anxiety disorders and drug dependence: evidence on sequence and specificity among adults.
Goodwin, Renee D; Stein, Dan J
2013-04-01
The goal of this study was to investigate the relation between specific anxiety disorders and substance dependence, adjusting for potentially confounding demographic factors (e.g. sex) and comorbidity (e.g. alcohol dependence, major depression), among adults in the USA. Data were drawn from the National Comorbidity Survey (NCS), a nationally representative population sample of the US adult population aged 15-54. The temporal sequence of onset of anxiety and substance dependence disorders was examined. Substance dependence temporally precedes several anxiety disorders, particularly panic disorder. Specifically, a history of past substance dependence predicts current panic disorder (odds ratio [OR] =2.62, 95% confidence interval [CI] =1.29, 5.32), social phobia (OR=1.7, 95%CI=1.12, 2.41), and agoraphobia (OR=1.78, 95%CI=1.08, 2.94). Conversely, in more than 50% of substance abuse disorder cases, in nearly 40% of post-traumatic stress disorder (PTSD) cases, and in nearly 30% of generalized anxiety disorder (GAD) cases, the anxiety disorder has first onset. Similarly, a lifetime history of social phobia, PTSD, or GAD significantly predicts lifetime substance dependence (OR=1.51 for social phobia, 2.06 for PTSD, 1.45 for GAD). For any particular anxiety disorder, a diagnosis of substance abuse can occur prior to or subsequent to an anxiety disorder. Nevertheless, there is also evidence for the specificity of some associations between anxiety and substance dependence disorders; these are independent of the effects of sex and other comorbid disorders, may be causal in nature, and deserve particular attention in clinical settings. The possibility that within a particular anxiety disorder there are a variety of mechanisms of association with various substances should be addressed in future work. © 2013 The Authors.

Although lower socioeconomic status has been linked to increased youth substance use, much less research has determined potential mechanisms explaining the association. The current longitudinal study tested whether alternative (i.e., pleasure gained from activities without any concurrent use of substances) and complementary (i.e., pleasure gained from activities in tandem with substance use) reinforcement mediate the link between lower socioeconomic status and youth substance use. Further, we tested whether alternative and complementary reinforcement and youth substance use gradually unfold over time and then intersect with one another in a cascading manner. Potential sex differences are also examined. Data were drawn from a longitudinal survey of substance use and mental health among high school students in Los Angeles. Data collection involved four semiannual assessment waves beginning in fall 2013 (N = 3395; M baseline age = 14.1; 47% Hispanic, 16.2% Asian, 16.1% multiethnic, 15.7% White, and 5% Black; 53.4% female). The results from a negative binomial path model suggested that lower parental socioeconomic status (i.e., lower parental education) was significantly related to an increased number of substances used by youth. The final path model revealed that the inverse association was statistically mediated by adolescents' diminished engagement in pleasurable substance-free activities (i.e., alternative reinforcers) and elevated engagement in pleasurable activities paired with substance use (i.e., complementary reinforcers). The direct effect of lower parental education on adolescent substance use was not statistically significant after accounting for the hypothesized mediating mechanisms. No sex differences were detected. Increasing access to and engagement in pleasant activities of high quality that do not need a reinforcement enhancer, such as substances, may be useful in interrupting the link between lower parental socioeconomic status and youth substance use.

HIV's effects on episodic memory have not been compared systematically between male and female substance-dependent individuals. We administered the Brief Visuospatial Memory Test-Revised (BVMT-R) to 280 substance-dependent HIV+ and HIV- men and women. Groups were comparable on demographic, substance use, and comorbid characteristics. There were no significant main effects of sex or HIV serostatus on BVMT-R performance, but HIV+ women performed significantly more poorly on delayed recall. This effect was most prominent among cocaine-dependent HIV+ women. Our findings are consistent with recent speculation that memory impairment may be more common among HIV+ women, particularly those with a history of cocaine dependence.

Most studies of attention deficit hyperactivity disorder (ADHD) in the substance dependence literature have assessed ADHD as a single, categorical entity. This approach limits characterization across the spectrum of ADHD symptomatology and may mask differences across the two core domains of ADHD symptoms-hyperactive-impulsive (HI) and inattention (IN). Further, it is unclear whether relations of HI and IN symptoms to substance dependence extend across drug classes and to the general population. This cross-sectional study investigated associations of lifetime ADHD HI and IN symptom levels to individual classes of lifetime substance dependence (alcohol, nicotine, depressants, opioids, stimulants, cannabis, hallucinogens, polysubstance) in a population-based sample of 34,653 American adults. HI and IN were associated with the majority of dependence diagnoses in a linear pattern, such that each additional symptom was associated with a proportional increase in odds of dependence. After adjusting for the overlap between symptom domains, both HI and IN uniquely associated with alcohol, nicotine, and polysubstance dependence, but only HI uniquely associated with dependence on illicit substances. These findings suggest that individuals in the general population with elevated levels of ADHD (particularly HI) symptoms are at risk for various forms of substance dependence and could benefit from preventive interventions.

This college-based questionnaire survey aimed to explore the individual, family, and peer correlates for cigarette smoking among first-year college students. The sample included 2918 first-year college students (males, 45.5%) recruited from a national university in Taiwan (participation rate, 79.1%). The participants reported on questions about various substances, attitudes toward substances, personality characteristics, psychopathology, suicidal behaviors, parenting style, family function and use of substances, and peer substance use. There were 263 (9.0%; males, 70.6%) current smokers. Compared to nonsmokers, college smokers were more extraverted and neurotic, and showed less harm avoidance, and more novelty seeking in their personality. They had more hostile, somatic, depressive, paranoid, and psychotic symptoms in terms of psychopathology. Smokers were more likely to use other substances, and to have suicidal ideations, wishes, plans, and attempts. Smokers perceived lower family cohesion, less care from their fathers, and less overprotection from their mothers. They were more likely to have peers and family members who also smoked or used other substances. The most associated correlates were male sex, older age, other substance use, novelty seeking, suicidal ideation and attempts, sibling and peer substance use, a prosubstance attitude, and less maternal overprotection. Our findings support the association of cigarette use in Taiwanese young adults with several individual, family, and peer factors identified in Western studies. Intervention in cigarette use should be multifaceted, by taking its correlates and the concurrent psychopathology, use of substances, and suicidality into consideration.

Objective To assess the performance of Diagnostic Cost Groups (DCGs) in explaining variation in concurrent utilization for a defined subgroup, patients with substance abuse (SA) disorders, within the Department of Veterans Affairs (VA). Data Sources A 60 percent random sample of veterans who used health care services during Fiscal Year (FY) 1997 was obtained from VA administrative databases. Patients with SA disorders (13.3 percent) were identified from primary and secondary ICD-9-CM diagnosis codes. Study Design Concurrent risk adjustment models were fitted and tested using the DCG/HCC model. Three outcome measures were defined: (1) “service days” (the sum of a patient's inpatient and outpatient visit days), (2) mental health/substance abuse (MH/SA) service days, and (3) ambulatory provider encounters. To improve model performance, we ran three DCG/HCC models with additional indicators for patients with SA disorders. Data Collection To create a single file of veterans who used health care services in FY 1997, we merged records from all VA inpatient and outpatient files. Principal Findings Adding indicators for patients with mild/moderate SA disorders did not appreciably improve the R-squares for any of the outcome measures. When indicators were added for patients with severe SA who were in the most costly category, the explanatory ability of the models was modestly improved for all three outcomes. Conclusions Modifying the DCG/HCC model with additional markers for SA modestly improved homogeneity and model prediction. Because considerable variation still remained after modeling, we conclude that health care systems should evaluate “off-the-shelf” risk adjustment systems before applying them to their own populations.

A framework for rigorously specifying the behavior of concurrent systems is proposed. It is based on the view of a concurrent system as a collection of interacting processes but no assumptions are made about the mechanisms for process synchronization and communication. A formal language is described that permits the expression of a broad range of logical and timing dependencies.

In order for a novel test method to be applied for regulatory purposes, its reliability and relevance, i.e., reproducibility and predictive capacity, must be demonstrated. Here, we examine the predictive capacity of a novel non-radioisotopic local lymph node assay, LLNA:BrdU-FCM (5-bromo-2'-deoxyuridine-flow cytometry), with a cutoff approach and inferential statistics as a prediction model. 22 reference substances in OECD TG429 were tested with a concurrent positive control, hexylcinnamaldehyde 25%(PC), and the stimulation index (SI) representing the fold increase in lymph node cells over the vehicle control was obtained. The optimal cutoff SI (2.7≤cutoff <3.5), with respect to predictive capacity, was obtained by a receiver operating characteristic curve, which produced 90.9% accuracy for the 22 substances. To address the inter-test variability in responsiveness, SI values standardized with PC were employed to obtain the optimal percentage cutoff (42.6≤cutoff <57.3% of PC), which produced 86.4% accuracy. A test substance may be diagnosed as a sensitizer if a statistically significant increase in SI is elicited. The parametric one-sided t-test and non-parametric Wilcoxon rank-sum test produced 77.3% accuracy. Similarly, a test substance could be defined as a sensitizer if the SI means of the vehicle control, and of the low, middle, and high concentrations were statistically significantly different, which was tested using ANOVA or Kruskal-Wallis, with post hoc analysis, Dunnett, or DSCF (Dwass-Steel-Critchlow-Fligner), respectively, depending on the equal variance test, producing 81.8% accuracy. The absolute SI-based cutoff approach produced the best predictive capacity, however the discordant decisions between prediction models need to be examined further. Copyright © 2015 Elsevier Inc.

Although genetic risk factors have been found to contribute to dependence on both licit and illicit psychoactive substances, we know little of how these risk factors interrelate. To clarify the structure of genetic and environmental risk factors for symptoms of dependence on cannabis, cocaine, alcohol, caffeine, and nicotine in males and females. Lifetime history by structured clinical interview. General community. Four thousand eight hundred sixty-five members of male-male and female-female pairs from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders. Main Outcome Measure Lifetime symptoms of abuse of and dependence on cannabis, cocaine, alcohol, caffeine, and nicotine. Controlling for greater symptom prevalence in males, genetic and environmental parameters could be equated across sexes. Two models explained the data well. The best-fit exploratory model contained 2 genetic factors and 1 individual environmental factor contributing to all substances. The first genetic factor loaded strongly on cocaine and cannabis dependence; the second, on alcohol and nicotine dependence. Nicotine and caffeine had high substance-specific genetic effects. A confirmatory model, which also fit well, contained 1 illicit drug genetic factor--loading only on cannabis and cocaine--and 1 licit drug genetic factor loading on alcohol, caffeine, and nicotine. However, these factors were highly intercorrelated (r = + 0.82). Large substance-specific genetic effects remained for nicotine and caffeine. The pattern of genetic and environmental risk factors for psychoactive substance dependence was similar in males and females. Genetic risk factors for dependence on common psychoactive substances cannot be explained by a single factor. Rather, 2 genetic factors-one predisposing largely to illicit drug dependence, the other primarily to licit drug dependence-are needed. Furthermore, a large proportion of the genetic influences on nicotine and particularly caffeine dependence appear to be specific to those substances.

Introduction. Addiction in women can expose them to malnutrition, high blood pressure, cancer, and some other dangerous diseases like hepatitis, AIDS, or other sexual transmitted diseases. The aim of this study was to assess illegal sexual relations in three groups of women. Methods. This is a cross-sectional study that was done on 236 girls and young women aged 16-25 years in 2012 in three groups: vulnerable women who have substance dependency (crimes that had made women incarcerated were considered as vulnerability in this study), invulnerable women who have substance dependency (substance dependent women without a history of incarceration), and a control group (women with no history of substance dependency or being in prison). Results. 43.8% of vulnerable women who have substance dependency had extramarital sexual relations; this percentage was 55.8% in invulnerable women who have substance dependency and 1.4% in the control group. Crystal and methamphetamine abuse was higher in addicts who had extramarital sexual relations and alcohol abuse was correlated with unsafe sexual intercourse (r = 0.36, P = 0.001). There was a statistically significant difference in extramarital sexual relation based on marital status (P < 0.001). Conclusions. Poverty, drug dependency, divorce, and alcohol consumption make women prone to other high risk behaviors that need more attention.
Specificity and transfer effects in time production skill: examining the role of attention.
Wohldmann, Erica L; Healy, Alice F; Bourne, Lyle E
2012-05-01
Two experiments examined transfer of a prospective, time production skill under conditions involving changes in concurrent task requirements. Positive transfer of the time production skill might be expected only when the attentional demands of the concurrent task were held constant from training to test. However, some positive transfer was found even when the concurrent task at retraining was made either easier or more difficult than the concurrent task learned during training. The amount and direction of transfer depended more on the pacing of the stimuli in the secondary task than on the difficulty of the secondary task, even though difficulty affects attentional demands more. These findings are consistent with the procedural reinstatement principle of skill learning, by which transfer from one task to another depends on an overlap in procedures required by the two skills.
The impact of cognitive load on delayed recall.
Camos, Valérie; Portrat, Sophie
2015-08-01
Recent studies have suggested that long-term retention of items studied in a working memory span task depends on the refreshing of memory items-more specifically, on the number of refreshing opportunities. However, it was previously shown that refreshing depends on the cognitive load of the concurrent task introduced in the working memory span task. Thus, cognitive load should determine the long-term retention of items assessed in a delayed-recall test if such retention relies on refreshing. In two experiments, while the amount of refreshing opportunities remained constant, we varied the cognitive load of the concurrent task by either introducing tasks differing in their attentional demands or varying the pace of the concurrent task. To verify that this effect was related to refreshing and not to any maintenance mechanism, we also manipulated the availability of subvocal rehearsal. Replicating previous results, increasing cognitive load reduced immediate recall. This increase also had a detrimental effect on delayed recall. Conversely, the addition of concurrent articulation reduced immediate but not delayed recall. This study shows that both working and episodic memory traces depend on the cognitive load of the concurrent task, whereas the use of rehearsal affects only working memory performance. These findings add further evidence of the dissociation between subvocal rehearsal and attentional refreshing.
Risk of inpatient stay for mental illness among individuals with substance use disorders.
Prince, Jonathan D
2012-09-01
Whereas most studies of inpatient stay for mental illness examine whether substance use is present, this study identified types or combinations of abused substances that most increased hospitalization risk. Logistic regression of data from the 2007 National Survey of Drug Use and Health (N=37,654) was used to predict past-year hospitalization of individuals with DSM-IV substance use disorders. Even after the inclusion of control variables, adults with four types of substance abuse or dependence were more likely to be hospitalized than adults without substance abuse or dependence. High-risk disorders included abuse of or dependence on opioid analgesics (odds ratio [OR]=6.85, p<.001), cocaine (OR=2.65, p<.05), alcohol and cocaine (OR=2.58, p<.05), and alcohol and marijuana (OR=3.10, p<.01). Researchers examining inpatient stays may find it beneficial to look at abuse of specific substances or combinations of substances, and efforts to prevent inpatient stays could target people with high-risk substance use disorders.

Delayed matching to sample and concurrent learning in nonamnesic humans with alcohol dependence.
Bowden, S C; Benedikt, R; Ritter, A J
1992-05-01
Small samples of alcohol-dependent subjects who showed no clinical signs of Wernicke-Korsakoff syndrome were compared with nonalcohol-dependent controls on two animal memory tests which are performed poorly by human amnesics. Compared to the control subjects, the alcohol-dependent subjects' performance was impaired on a version of the delayed matching to sample task. On concurrent discrimination learning the overall group difference just failed to reach significance. The results are interpreted as suggesting that behavioural impairment may occur in alcohol-dependent subjects who are not clinically amnesic, and that the impairment is similar in type to that observed in cases of severe Wernicke-Korsakoff syndrome.

A cross-sectional study was conducted in the year 2008 among 174 children in observation homes in Hyderabad, India, to estimate the distribution of inhalant (whitener) use among this population. Data were collected using an instrument developed for this purpose. About 61% of the children were boys and their mean age was 12.2 years (range 5-18 years). Whitener use was found in 35% of the children along with concurrent use of other substances. Peer pressure was the commonest cause reported for initiating substance use. The high prevalence is an important concern for the Indian policymakers given the large number of street children in Indian cities.

Existing research has demonstrated the significance of situational antecedents to substance use. The current study used a cluster analytic approach to identify groups of club drug users who report using substances in similar situations (assessed by the Inventory of Drug Taking Situations) with longitudinal data from 400 active drug users. A three-cluster solution emerged in baseline data and was replicated in 12-month follow-up data. Groups were identified as Situationally Restricted, Pleasure Driven, and Situationally Broad users. Group differences were observed on measures of mental health, attitudes towards substance use, amount of substance use, and rates of substance dependence. Cluster membership predicted substance dependence after controlling for past dependence, current use, and current depression/anxiety. PMID:20696530

The current series of studies is a preliminary exploration of the psychometric properties of the SURPS in two populations (undergraduate and high school students). In study 1, an analysis of the internal structure of two versions of the SURPS shows that the abbreviated version best reflects the 4-factor structure.

In Study 3, the SURPS was administered in a more youthful population to test its sensitivity in identifying younger problematic drinkers. The results from the current series of studies demonstrate support for the reliability and construct validity of the SURPS, and suggest that four personality dimensions may be linked to substance-related behavior through different reinforcement processes.

Objective: The aim of this study was to examine how reasons for substance use at age 18 relate to alcohol and marijuana use at ages 18 and 35 and to symptoms of alcohol use disorder and marijuana use disorder at age 35. Method: Bivariate correlation and multivariate regression analyses were conducted to examine the prediction of substance use and misuse by social/recreational, coping with negative affect, compulsive, and drug effect reasons for alcohol and marijuana use. Control variables included gender, race/ethnicity, parent education, and previous substance use (for age 35 outcomes). Results: Social/recreational, coping, and drug effect reasons for drinking predicted symptoms of alcohol use disorder 17 years later. Reasons for marijuana use were generally associated only with concurrent marijuana use; an exception was that drug effect reasons predicted marijuana use disorder at age 35. Conclusions: The long-term longitudinal predictive power of reasons for alcohol use (and, to a lesser extent, for marijuana use) suggests that adolescents' self-reported reasons, in particular those involving regulating emotions and experiences, may be early risk factors for continued use and misuse of substances into adulthood.

This study aimed to evaluate synthetic cannabinoid (SC)-induced psychosis in terms of patient profile and clinical characteristics with reference to concurrently hospitalized schizophrenic patients. A total of 81 male patients diagnosed with psychotic disorder induced by the use of SCs (n=50; mean (standard deviation [SD]) age: 25.9 (5.5) years) or with schizophrenia (n=31, mean (SD) age: 42.9 (11.6) years) based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosis criteria who were concurrently hospitalized at Erenköy Mental and Neurological Diseases Training and Research Hospital were included in this cross-sectional study. Data on sociodemographic characteristics, Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), Frontal Assessment Battery (FAB), Hamilton Rating Scale for Depression (HRSD), and Hamilton Anxiety Rating Scale (HAM-A) were recorded in all the patients. Mean (SD) age at disease onset in SC-induced psychosis patients was 22.3 (5.6) years; 26.0% had suicidal ideation and 58.4% were hospitalized involuntarily. Marijuana was the most common first used substance (72.0%), and solitary use of SC was noted in 38.0% of patients. SC-induced psychosis patients had similar PANSS positive, BPRS, HRSD, and FAB scores and significantly lower PANSS negative scores (18.0 [6.5] vs 22.3 [6.0], P=0.004) than patients with schizophrenia, while they had similar HAM-A scores (17.8 [10.3] vs 21.6 [5.5], P=0.085) as young schizophrenics. Age at onset for SC (r=0.364, P=0.05) or substance (r=0.395, P=0.01) use was correlated positively with total FAB scores. In conclusion, our findings revealed SC-induced psychosis to influence young individuals and be associated with remarkable rates of suicidal ideation and involuntary hospitalization as well as similar clinical picture with schizophrenia in terms of PANSS positive, BPRS, HRSD, HAM-A, and FAB scores. Younger age at onset was associated with poorer frontal lobe functions overall, regardless of the type of substance, and with poorer inhibitory control and programming performance in case of SC use.

Abundant evidence from family, adoption, and twin studies point to large genetic contributions to individual differences in vulnerability to develop dependence on one or more addictive substances. Twin data suggest that most of this genetic vulnerability is shared by individuals who are dependent on a variety of addictive substances. Molecular genetic studies, especially genomewide and candidate gene association studies, have elucidated common haplotypes in dozens of genes that appear to make polygenic contributions to vulnerability to developing dependence. Most genes that harbor currently identified addiction-associated haplotypes are expressed in the brain. Haplotypes in many of the same genes are identified in genomewide association studies that compare allele frequencies in substance dependent vs. control individuals from European, African, and Asian racial/ethnic backgrounds. Many of these addiction-associated haplotypes display pleiotropic influences on a variety of related brain-based phenotypes that display 1) substantial heritability and 2) clinical cooccurence with substance dependence.

This study examines the relationship between self-reported symptoms of substance dependence and risky sexual behavior among 187 HIV-negative men who have sex with men. In a supplement to a Chicago household survey, using random probability sampling, men who reported consensual sex with other men or who identified as gay or bisexual were selected for interviews. Participants reported on sexual behavior, substance use, and symptoms of substance dependence related to past year use of alcohol, marijuana, cocaine, and sedatives, tranquilizers or pain relievers. Risky sexual behavior was defined as unprotected insertive or receptive anal intercourse plus having multiple partners, casual partners, or a partner who was HIV positive or of unknown serostatus. Risky sexual behavior in the past six months was significantly and positively associated with alcohol dependence symptoms, cocaine dependence symptoms (receptive only), and prescription drug dependence symptoms (insertive only). Confirmatory factor analyses revealed that dependence symptoms loaded on separate factors by substance, which in turn loaded on an overarching dependence symptoms factor. In structural equation models, individual substance factors were not significantly associated with sexual risk behavior, however the higher order dependence symptoms factor was significantly and positively associated with both receptive and insertive risk behavior. MSM with symptoms of multiple substance use dependencies are more likely to be engaged in sexual behavior that places them at risk for acquiring HIV and other sexually transmitted infections. Alcohol and drug abuse treatment providers should be aware of the need for HIV testing and counseling in this population. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

The present study sought to inform models of risk for drugged driving through empirically identifying patterns of marijuana use, alcohol use, and related driving behaviors. Perceived dangerousness and consequences of drugged driving were evaluated as putative influences on risk patterns. We used latent profile analysis of survey responses from 897 college students to identify patterns of substance use and drugged driving. We tested the hypotheses that low perceived danger and low perceived likelihood of negative consequences of drugged driving would identify individuals with higher-risk patterns. Findings from the latent profile analysis indicated that a four-profile model provided the best model fit. Low-level engagers had low rates of substance use and drugged driving. Alcohol-centric engagers had higher rates of alcohol use but low rates of marijuana/simultaneous use and low rates of driving after substance use. Concurrent engagers had higher rates of marijuana and alcohol use, simultaneous use, and related driving behaviors, but marijuana-centric/simultaneous engagers had the highest rates of marijuana use, co-use, and related driving behaviors. Those with higher perceived danger of driving while high were more likely to be in the low-level, alcohol-centric, or concurrent engagers' profiles; individuals with higher perceived likelihood of consequences of driving while high were more likely to be in the low-level engagers group. Findings suggested that college students' perceived dangerousness of driving after using marijuana had greater influence on drugged driving behaviors than alcohol-related driving risk perceptions. These results support targeting marijuana-impaired driving risk perceptions in young adult intervention programs.

The World Health Organization (WHO) World Mental Health (WMH) Survey Initiative uses the Composite International Diagnostic Interview (CIDI). The first 13 surveys only assessed substance dependence among respondents with a history of substance abuse; later surveys also assessed substance dependence without symptoms of abuse. We compared results across the two sets of surveys to assess implications of the revised logic and develop an imputation model for missing values of lifetime dependence in the earlier surveys. Lifetime dependence without symptoms of abuse was low in the second set of surveys (0.3% alcohol, 0.2% drugs). Regression-based imputation models were built in random half-samples of the new surveys and validated in the other half. There were minimal differences for imputed and actual reported cases in the validation dataset for age, gender and quantity; more mental disorders and days out of role were found in the imputed cases. Concordance between imputed and observed dependence cases in the full sample was high for alcohol [sensitivity 88.0%, specificity 99.8%, total classification accuracy (TCA) 99.5%, area under the curve (AUC) 0.94] and drug dependence (sensitivity 100.0%, specificity 99.8%, TCA 99.8%, AUC 1.00). This provides cross-national evidence of the small degree to which lifetime dependence occurs without symptoms of abuse. Imputation of substance dependence in the earlier WMH surveys improved estimates of dependence. Copyright © 2017 John Wiley & Sons, Ltd.
Concurrent credit portfolio losses
Sicking, Joachim; Schäfer, Rudi
2018-01-01
We consider the problem of concurrent portfolio losses in two non-overlapping credit portfolios. In order to explore the full statistical dependence structure of such portfolio losses, we estimate their empirical pairwise copulas. Instead of a Gaussian dependence, we typically find a strong asymmetry in the copulas. Concurrent large portfolio losses are much more likely than small ones. Studying the dependences of these losses as a function of portfolio size, we moreover reveal that not only large portfolios of thousands of contracts, but also medium-sized and small ones with only a few dozens of contracts exhibit notable portfolio loss correlations. Anticipated idiosyncratic effects turn out to be negligible. These are troublesome insights not only for investors in structured fixed-income products, but particularly for the stability of the financial sector. JEL codes: C32, F34, G21, G32, H81.

Sociological work on social capital and its impact on health behaviours have been translated into the addiction field in the form of 'recovery capital' as the construct for assessing individual progress on a recovery journey. Yet there has been little attempt to quantify recovery capital. The aim of the project was to create a scale that assessed addiction recovery capital. Initial focus group work identified and tested candidate items and domains followed by data collection from multiple sources to enable psychometric assessment of a scale measuring recovery capital. The scale shows moderate test-retest reliability at 1 week and acceptable concurrent validity. Principal component analysis determined single factor structure. The Assessment of Recovery Capital (ARC) is a brief and easy to administer measurement of recovery capital that has acceptable psychometric properties and may be a useful complement to deficit-based assessment and outcome monitoring instruments for substance dependent individuals in and out of treatment. © 2012 Australasian Professional Society on Alcohol and other Drugs.
Treatment dropout in drug-addicted women: are eating disorders implicated?

A high prevalence of eating disorders among drug-addicted female patients has been noted, and it could be associated to psychopathological underlying factors. Our aim was to assess eating disorder traits in women approaching a residential program for drug addiction. We hypothesized that these traits would correlate to more general psychopathological factors, and would influence treatment relapse. A sample of 204 substance dependent women attending a residential treatment was screened for psychopathological indices, and follow-up data were obtained at the end of the treatment. Clients had a high risk for eating disorders (15%), and lifetime prevalence was even higher (20%). Disordered eating was associated to psychopathological distress, in particular harm avoidance resulted significantly lower (p=0.005), evoking higher unresponsiveness to danger. Drug addiction treatment outcome is associated to completion of defined programs, and eating disorder was a key covariable in determining treatment relapse or success (p=0.03). Clinicians should be aware of this potential co-morbidity, and concurrent treatments should be attempted, in order to prevent symptomatic shifting.

The occurrence of repetitive behaviours that are often harmful has been attributed to traits traditionally described as "impulsive" or "compulsive" e.g. substance dependence, excessive gambling, and hoarding. These behaviours are common and often co-occur in both the general population and psychiatric populations. The lack of measures to concurrently index a range of such behaviours led to the development of the Impulsive-Compulsive Behaviours (ICB) Checklist. This study aims to validate the ICB Checklist in a general community sample. Factor analyses revealed a two-factor structure, demonstrating good model fit in two independent samples. These were labelled Impulsive-Compulsions and Compulsive-Impulsions, comprising of classically compulsive and impulsive behaviours respectively. Reliability and construct validity were further confirmed using correlations with existing measures of impulsivity and compulsivity. Results suggest that the ICB Checklist is a valid and practical assessment that can be used to monitor behavioural clusters characterised by deficits in inhibition. Copyright © 2016 Elsevier Ltd.

The present article reviews whether available efficacy and safety data support the pharmacological treatment of adult attention-deficit/hyperactivity disorder (ADHD) in patients with concurrent substance use disorders (SUD). Arguments for and against treating adult ADHD with active SUD are discussed. Findings from 19 large open studies and controlled clinical trials show that the use of atomoxetine or extended-release methylphenidate formulations, together with psychological therapy, yield promising though inconclusive results about short term efficacy of these drugs in the treatment of adult ADHD in patients with SUD and no other severe mental disorders. However, the efficacy of these drugs is scant or lacking for treating concurrent SUD. No serious safety issues have been associated with these drugs in patients with co-morbid SUD-ADHD, given their low risk of abuse and favourable side effect and drug–drug interaction profile. The decision to treat adult ADHD in the context of active SUD depends on various factors, some directly related to SUD-ADHD co-morbidity (e.g. degree of diagnostic uncertainty for ADHD) and other factors related to the clinical expertise of the medical staff and availability of adequate resources (e.g. the means to monitor compliance with pharmacological treatment). Our recommendation is that clinical decisions be individualized and based on a careful analysis of the advantages and disadvantages of pharmacological treatment for ADHD on a case-by-case basis in the context of active SUD.

Conduct problems, substance use, and risky sexual behavior have been shown to coexist among adolescents, which may lead to significant health problems. The current study was designed to examine relations among these problem behaviors in a community sample of children at high risk for conduct disorder. A latent growth model of childhood conduct problems showed a decreasing trend from grades K to 5. During adolescence, four concurrent conduct problem and substance use trajectory classes were identified (high conduct problems and high substance use, increasing conduct problems and increasing substance use, minimal conduct problems and increasing substance use, and minimal conduct problems and minimal substance use) using a parallel process growth mixture model. Across all substances (tobacco, binge drinking, and marijuana use), higher levels of childhood conduct problems during kindergarten predicted a greater probability of classification into more problematic adolescent trajectory classes relative to less problematic classes. For tobacco and binge drinking models, increases in childhood conduct problems over time also predicted a greater probability of classification into more problematic classes. For all models, individuals classified into more problematic classes showed higher proportions of early sexual intercourse, infrequent condom use, receiving money for sexual services, and ever contracting an STD. Specifically, tobacco use and binge drinking during early adolescence predicted higher levels of sexual risk taking into late adolescence. Results highlight the importance of studying the conjoint relations among conduct problems, substance use, and risky sexual behavior in a unified model. Copyright © 2010 Elsevier Ireland Ltd.

Sexual minority adolescents are more likely than their heterosexual peers to use substances. This study tested factors that contribute to sexual orientation disparities in substance use among racially and ethnically diverse adolescents. Specifically, we examined how both minority stress (i.e., homophobic bullying) and social norms (i.e., descriptive and injunctive norms) may account for sexual orientation disparities in recent and lifetime use of four substances: tobacco, alcohol, marijuana, and prescription drugs. A probability sample of middle and high school students (N=3012; aged 11-18 years old; 71.2% racial and ethnic minorities) using random cluster methods was obtained in a mid-size school district in the Southeastern United States. Sexual minority adolescents were more likely than heterosexual adolescents to use substances, experience homophobic bullying, and report higher descriptive norms for close friends and more permissive injunctive norms for friends and parents. While accounting for sociodemographic characteristics, multiple mediation models concurrently testing all mediators indicated that higher descriptive and more permissive injunctive norms were significant mediators of the associations between sexual orientation and recent and lifetime use of the four substances, whereas homophobic bullying was not a significant mediator of the associations between sexual orientation and recent and lifetime use of any of the substances. Descriptive and injunctive norms, in conjunction with minority stress, are important to consider in explaining sexual orientation disparities in substance use among racially diverse adolescents. These results have implications for substance use interventions among sexual minority adolescents. Copyright © 2017 Elsevier B.V. All rights reserved.

Substance use and depression often co-occur, complicating treatment of both substance use and depression. Despite research documenting age-related trends in both substance use and depression, little research has examined how the associations between substance use behaviors and depression changes across the lifespan. This study examines how the associations between substance use behaviors (daily smoking, regular heavy episodic drinking (HED), and marijuana use) and depressive symptoms vary from adolescence into young adulthood (ages 12-31), and how these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we implemented time-varying effect models (TVEM), an analytic approach that estimates how the associations between predictors (e.g., substance use measures) and an outcome (e.g., depressive symptoms) vary across age. Marijuana use and daily smoking were significantly associated with depressive symptoms at most ages from 12 to 31. Regular HED was significantly associated with depressive symptoms during adolescence only. In bivariate analyses, the association with depressive symptoms for each substance use behavior was significantly stronger for females at certain ages; when adjusting for concurrent substance use in a multivariate analysis, no gender differences were observed. While the associations between depressive symptoms and both marijuana and daily smoking were relatively stable across ages 12-31, regular HED was only significantly associated with depressive symptoms during adolescence. Understanding age and gender trends in these associations can help tailor prevention efforts and joint treatment methods in order to maximize public health benefit.

Evidence suggests that substance abuse negatively affects both psychiatric symptom severity and quality of life (QOL) in people with severe mental illness (SMI). However, these relationships have not been examined simultaneously, nor have they been characterized over time. Thus, it is difficult to appreciate the extent to which substance abuse exerts an enduring effect on psychiatric symptoms and distress and/or QOL in this population. The purpose of this study is to test a conceptual model linking these factors together. Subjects were participants in a longitudinal evaluation of community mental healthcare in Ontario (n = 133). Comprehensive consumer assessments were conducted at treatment entry, and at 9 and 18 months. Subjects were receiving intensive case management or assertive community treatment throughout the 18-month study period. Structural equation modelling was used to examine the concurrent and longitudinal relationships between substance abuse, symptoms and distress, and QOL. The prevalence of substance abuse was 55.0%. The SEM analysis suggested that substance abuse at baseline was associated with elevated symptomatology and distress and lower QOL, and that these effects endured after 18 months of treatment. Psychiatric symptoms and distress mediated the negative relationship between substance abuse and QOL. The mediating role played by symptom and distress levels in the relationship between substance abuse and QOL suggests the importance of closely monitoring changes in these factors among SMI patients with substance problems. Tracking symptom severity and distress levels over time will allow service providers to intervene and potentially improve the QOL of individuals with SMI.

Substance abuse and criminality share a complex relationship. The rates of substance use among the prisoners, and that of criminal acts among substance users in community setting are high. Data from South Asian countries, including from India are inadequate. This study aimed to assess the pattern of criminal acts among opioid-dependent subjects and their substance use pattern in the month before, during and after imprisonment. Using a cross-sectional study design and purposive sampling, opioid-dependent subjects (n=101) attending two community drug treatment clinics who have had any contact with the law were assessed using a specifically-designed tool to record criminal acts and substance use before, during and after last imprisonment. Most subjects (93%) had committed illegal acts in their lifetime. Physical assault was the most common illegal act, while 23% reported selling drugs and 9% reported committing serious crimes. About 95% were arrested and 92% had spent time in police lockups. About 29% were arrested for drugs possession or drug use, and 3% of injecting drug users arrested for carrying injection equipment. About 85% had been imprisoned at least once, of whom 88% used psychoactive substances in the 1-month period before their last imprisonment. Opioids were the most common substances used daily (68%), followed by cannabis (34%) and alcohol (22%). Ninety-seven percent reported the availability of substances in prisons, and 65% also used substances during their last imprisonment. Cannabis (35%) was the most common substances used in prison followed by opioids (19%). Seventy-six percent used substances soon after prison release, and 13% of opioid users experienced opioid overdose soon after prison release. Use of cannabis, injecting drugs, and opioid use before imprisonment were predictors of substance use in prison. Opioid-dependent people have various contacts with the law, including imprisonment. Many users are dependent on substances during prison-entry, which is an important reason for their continued substance use in prisons. There is a need to provide substance abuse treatment across all stages of criminal justice system. Copyright © 2015 Elsevier Inc. All rights reserved.

South Africa is experiencing a growing methamphetamine problem, and there is concern that methamphetamine use may accelerate HIV transmission. There has been little research on the HIV prevention needs of methamphetamine users receiving substance abuse treatment in South Africa. This study assessed the prevalence and correlates of HIV risk behaviors among 269 methamphetamine users entering substance abuse treatment in two clinics in Cape Town. The prevalence of sexual risk behaviors was high among sexually active participants: 34 % multiple partners, 26 % unprotected intercourse with a casual partner, and 24 % sex trading for money/methamphetamine. The strongest predictor of all sexual risk behaviors was concurrent other drug use. Over half had not been HIV tested in the past year, and 25 % had never been tested, although attitudes toward HIV testing were overwhelmingly positive. This population of primarily heterosexual, non-injecting methamphetamine users is a high-risk group in need of targeted HIV prevention interventions. Substance abuse treatment is an ideal setting in which to reach methamphetamine users for HIV services.

Two major nomenclatures, Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) and International Classification of Diseases, tenth edition (ICD-10), currently define substance use disorders for broad audiences of users with different training, experience and interests. A comparison of these definitions and their implications for DSM-V and ICD-11 has not been available. The background for the dependence concept and abuse, harmful use, withdrawal, substance-induced disorders and remission and other substance-related conditions is reviewed. Reliability evidence is presented, as is validity evidence from approaches including psychometric, genetic and animal studies. The relevance of the DSM-IV and ICD-10 compared to alternative systems (e.g. the Addiction Severity Index) is considered. Reliability and psychometric validity evidence for substance dependence is consistently strong, but more mixed for abuse and harmful use. Findings on the genetics of alcohol disorders support the validity of the dependence concept, while animal studies underscore the centrality of continued use despite negative consequences to the concept of dependence. While few studies on substance-induced disorders have been conducted, those published show good reliability and validity when elements of DSM-IV and ICD-10 are combined. Dependence in DSM-V and ICD-11 should be retained, standardizing both criteria sets and adding a severity measure. The consequences of heavy use should be measured independently of dependence; add cannabis withdrawal if further research supports existing evidence; conduct further studies of the substance-induced psychiatric categories; standardize their criteria across DSM-V and ICD-11; develop a theoretical basis for better remission criteria; consider changing substance 'abuse' to substance 'dysfunction disorder'; and conduct clinician education on the value of the diagnostic criteria.

The objective of this study is to examine the effect of fetal alcohol exposure on later substance dependence using an adoption study method. One hundred ninety-seven adoptees were interviewed for substance abuse disorders, including nicotine, alcohol, and drug dependence. Twenty-one adoptees had mothers who drank during pregnancy. Adoptees with fetal alcohol exposure were compared with those without fetal alcohol exposure for symptoms of adult nicotine, alcohol, and drug dependence. Adoptee symptom counts for alcohol, drug, and nicotine dependence were higher for those exposed to alcohol in utero. The effect of fetal alcohol exposure remained after controlling for gender, biological parent alcohol dependence diagnosis, birth weight, gestational age and other environmental variables. Fetal alcohol exposure may produce increased risk for later nicotine, alcohol, and drug dependence. Possible effects of fetal alcohol exposure on development of adult substance use patterns needs attention in genetic studies of substance abuse.

It is well established that craving increases following exposure to substance-related 'cues', but the role of life-styles or substance use habits that are unique to each person remains poorly understood. This study examines the association of substance-specific and personal cues with craving and substance use in daily life. Ecological momentary assessment was used during a 2-week period. Data were collected in a French out-patient addiction treatment centre. A total of 132 out-patients beginning treatment for alcohol, tobacco, cannabis or opiate addiction were included. Using mobile technologies, participants were questioned four times per day relative to craving, substance use and exposure to either substance-specific cues (e.g. seeing a syringe) or personal cues unique to that individual (e.g. seeing the specific person with whom the substance is used). Craving intensity was associated with the number of concurrently assessed substance-specific cues (t = 4.418, P < 0.001) and person-specific cues (t = 4.006, P < 0.001) when analysed jointly within the same model. However, only person-specific cues were associated with increases in craving over subsequent hours of the day (t = 2.598, P < 0.05). Craving intensity, in turn, predicted increases in later substance use (t = 4.076, P < 0.001). Causal mediation analyses demonstrated that the association of cues with later substance use was mediated by craving intensity (mediated effect = 0.007, 95% confidence interval = 0.004-0.011). Unique person-specific cues appear to have a robust effect on craving addictive substances, and the duration of this association may persist longer than for more general substance-specific cues. Mobile technologies provide new opportunities for understanding these person-specific risk factors and for providing individually tailored interventions. © 2015 Society for the Study of Addiction.

Biodiesel fuel test substances Rape Ethyl Ester (REE), Rape Methyl Ester (RME), Neat Rape Oil (NR), Say Methyl Ester (SME), Soy Ethyl Ester (SEE), Neat Soy Oil (NS), and proportionate combinations of RME/diesel and REE/diesel were studied to test the biodegradability of the test substances in an aerobic aquatic environment using the EPA 560/6-82-003 Shake Flask Test Method. A concurrent analysis of Phillips D-2 Reference Diesel was also performed for comparison with a conventional fuel. The highest rates of percent CO{sub 2} evolution were seen in the esterified fuels, although no significant difference was noted between them. Ranges of percentmore » CO{sub 2} evolution for esterified fuels were from 77% to 91%. The neat rape and neat soy oils exhibited 70% to 78% CO{sub 2} evolution. These rates were all significantly higher than those of the Phillips D-2 reference fuel which evolved from 7% to 26% of the organic carbon to CO{sub 2}. The test substances were examined for BOD{sub 5} and COD values as a relative measure of biodegradability. Water Accommodated Fraction (WAF) was experimentally derived and BOD{sub 5} and COD analyses were carried out with a diluted concentration at or below the WAF. The results of analysis at WAF were then converted to pure substance values. The pure substance BOD{sub 5} and COD values for test substances were then compared to a control substance, Phillips D-2 Reference fuel. No significant difference was noted for COD values between test substances and the control fuel. (p > 0.20). The D-2 control substance was significantly lower than all test substances for BCD, values at p << 0.01. RME was also significantly lower than REE (p < 0.05) and MS (p < 0.01) for BOD{sub 5} value.« less

Violence is a salient concern among veterans, yet relationships between psychiatric comorbidity, social networks, and aggression are poorly understood. We examined associations between biopsychosocial factors (substance use, posttraumatic stress disorder [PTSD], and social network behaviors) with aggression. We recruited veterans endorsing past-year aggression and substance use (N = 180) from Department of Veterans Affairs outpatient treatment clinics. Main and interaction effects between probable PTSD, substance use, social network violence and substance use, and veteran violence were examined with negative binomial regressions-specifically, physical aggression toward a relationship partner (PA-P), physical injury of a partner (PI-P), physical aggression toward nonpartners (PA-NP), and physical injury of nonpartners (PI-NP). Alcohol use yielded consistent main effects. PTSD and social network violence demonstrated main effects for PA-NP and PI-NP. PTSD and social network violence interacted to predict PA-P such that social network violence appeared salient only in the context of PTSD. PTSD was associated with PI-P, PA-NP, and PI-NP in social network substance use models. In the PA-P model including social network substance use, veterans with PTSD reported greater PA-P in the context of greater social network substance use, whereas veterans without PTSD endorsed PA-P concurrent with greater alcohol frequency. For PI-P, PTSD interacted with alcohol to predict a greater likelihood of partner injury in the context of social network substance use. Investigated variables demonstrated unique associations within the context of specific relationships and the severity of behaviors. Overall, the findings underscore the importance of biopsychosocial models for understanding veteran violence. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Cannabis use is reported to increase the risk for psychosis, but no prospective study has longitudinally examined drug use and symptoms concurrently in clinical high risk cases. We prospectively followed for up to 2 years 32 cases who met research criteria for prodromal psychosis to examine the relationship between substance use and clinical measures. Cases with a baseline history of cannabis use (41%) were older, but did not differ in clinical measures. Longitudinal assessments showed these cases had significantly more perceptual disturbances and worse functioning during epochs of increased cannabis use that were unexplained by concurrent use of other drugs or medications. These data demonstrate that cannabis use may be a risk factor for the exacerbation of subthreshold psychotic symptoms, specifically perceptual disturbances, in high risk cases.

Few studies linking single motherhood and maternal smoking during pregnancy consider correlated risk from problem substance use beyond history of smoking and concurrent use of alcohol. In the present study, we used propensity score methods to examine whether the risk of smoking during pregnancy associated with single motherhood is the result of potential confounders, including alcohol dependence. Data were drawn from mothers participating in a birth cohort study of their female like-sex twin offspring (n = 257 African ancestry; n = 1,711 European or other ancestry). We conducted standard logistic regression models predicting smoking during pregnancy from single motherhood at twins' birth, followed by propensity score analyses comparing single-mother and two-parent families stratified by predicted probability of single motherhood. In standard models, single motherhood predicted increased risk of smoking during pregnancy in European ancestry but not African ancestry families. In propensity score analyses, rates of smoking during pregnancy were elevated in single-mother relative to two-parent European ancestry families across much of the spectrum a priori risk of single motherhood. Among African ancestry families, within-strata comparisons of smoking during pregnancy by single-mother status were nonsignificant. These findings highlight single motherhood as a unique risk factor for smoking during pregnancy in European ancestry mothers, over and above alcohol dependence. Additional research is needed to identify risks, beyond single motherhood, associated with smoking during pregnancy in African ancestry mothers.
Mechanisms and genetic factors underlying co-use of nicotine and alcohol or other drugs of abuse.

Concurrent use of tobacco and alcohol or psychostimulants represents a major public health concern, with use of one substance influencing consumption of the other. Co-abuse of these drugs leads to substantial negative health outcomes, reduced cessation, and high economic costs, but the underlying mechanisms are poorly understood. Epidemiological data suggest that tobacco use during adolescence plays a particularly significant role. Adolescence is a sensitive period of development marked by major neurobiological maturation of brain regions critical for reward processing, learning and memory, and executive function. Nicotine exposure during this time produces a unique and long-lasting vulnerability to subsequent substance use, likely via actions at cholinergic, dopaminergic, and serotonergic systems. In this review, we discuss recent clinical and preclinical data examining the genetic factors and mechanisms underlying co-use of nicotine and alcohol or cocaine and amphetamines. We evaluate the critical role of nicotinic acetylcholine receptors throughout, and emphasize the dearth of preclinical studies assessing concurrent drug exposure. We stress important age and sex differences in drug responses, and highlight a brief, low-dose nicotine exposure paradigm that may better model early use of tobacco products. The escalating use of e-cigarettes among youth necessitates a closer look at the consequences of early adolescent nicotine exposure on subsequent alcohol and drug abuse.
Choice and conditioned reinforcement.
Fantino, E; Freed, D; Preston, R A; Williams, W A
1991-01-01
A potential weakness of one formulation of delay-reduction theory is its failure to include a term for rate of conditioned reinforcement, that is, the rate at which the terminal-link stimuli occur in concurrent-chains schedules. The present studies assessed whether or not rate of conditioned reinforcement has an independent effect upon choice. Pigeons responded on either modified concurrent-chains schedules or on comparable concurrent-tandem schedules. The initial link was shortened on only one of two concurrent-chains schedules and on only one of two corresponding concurrent-tandem schedules. This manipulation increased rate of conditioned reinforcement sharply in the chain but not in the tandem schedule. According to a formulation of delay-reduction theory, when the outcomes chosen (the terminal links) are equal, as in Experiment 1, choice should depend only on rate of primary reinforcement; thus, choice should be equivalent for the tandem and chain schedules despite a large difference in rate of conditioned reinforcement. When the outcomes chosen are unequal, however, as in Experiment 2, choice should depend upon both rate of primary reinforcement and relative signaled delay reduction; thus, larger preferences should occur in the chain than in the tandem schedules. These predictions were confirmed, suggesting that increasing the rate of conditioned reinforcement on concurrent-chains schedules may have no independent effect on choice. PMID:2037826
Exploring the nature of the relationship between child sexual abuse and substance use among women.

This study investigated whether child abuse (CSA) was associated with earlier substance use and greater severity of substance dependence and what aspects of CSA might predict substance abuse. The study compared (a) drug and alcohol treatment clients with and without a history of CSA and (b) CSA survivors outside drug and alcohol treatment who did or did not have current substance abuse. Semi-structured interviews took place at participants' homes, treatment agencies or the research centre. Volunteer participants included 100 women recruited from drug and alcohol treatment programmes and 80 CSA survivors recruited through CSA counseling services and medial advertising. The results focus on data from the Opiate Treatment Index, Severity of Alcohol Dependence Questionnaire, Substance Dependence Scale, Self-Esteem Inventory and self-reported histories of CSA. There were no differences between CSA survivors and other drug and alcohol treatment clients in their severity of dependence. Women with a history of CSA more frequently identified stimulants as their main problem drug and reported an earlier age of first intoxication and earlier use of inhalants. Among abused CSA survivors outside drug and alcohol treatment, women with current substance abuse had typically been abused during adolescence by someone outside the family, whereas those without current substance abuse were typically abused by family members before adolescence. The results suggest that adolescence is a crucial time for the influence of CSA experiences on substance abuse.

Objectives The aims of this study were to estimate the frequency and course of substances use disorders in Latino patients with schizophrenia and to ascertain risk factors associated with substance use disorders in this population. Method We studied 518 subjects with schizophrenia recruited for a genetic study from the Southwest United States, Mexico, and Central America (Costa Rica and Guatemala). Subjects were assessed using structured interviews and a best estimate consensus process. Logistic regression, χ2, t- test, Fisher’s exact test, and Yates’ correction, as appropriate, were performed to assess the sociodemographic variables associated with dual diagnosis. We defined substance use disorder as either alcohol or substance abuse or dependence. Results Out of 518 patients with schizophrenia, 121 (23.4%) had substance use disorders. Comorbid substance use disorders were associated with male gender, residence in the United States, immigration of Mexican men to the United State, history of depressive syndrome or episode, and being unemployed. The most frequent substance use disorder was alcohol abuse/dependence, followed by marijuana abuse/dependence, and solvent abuse/dependence. Conclusion This study provides data suggesting that depressive episode or syndrome, unemployment, male gender, and immigration of Mexican men to the United States were factors associated with substance use disorder comorbidity in schizophrenia. Binary logistic regression showed that country of residence was associated with substance use disorder in schizophrenic patients. The percentage of subjects with comorbid substance use disorders was higher in the Latinos living in the United States compared with subjects living in Central America and Mexico. PMID:20303714

Clinical and population-based samples show high comorbidity between Substance Use Disorders (SUDs) and Axis II Personality Disorders (PDs). However, Axis II disorders are frequently comorbid with each other, and existing research has generally failed to distinguish the extent to which SUD/PD comorbidity is general or specific with respect to both specific types of PDs and specific types of SUDs. We sought to determine whether ostensibly specific comorbid substance dependence-Axis II diagnoses (e.g., alcohol use dependence and borderline personality disorder) are reflective of more pervasive or general personality pathology or whether the comorbidity is specific to individual PDs. Face-to-face interview data from Wave 1 and Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Participants included 34,653 adults living in households in the United States. We used hierarchical factor models to statistically partition general and specific personality disorder dimensions while simultaneously testing for specific PD-substance dependence relations. Results indicated that substance dependence-Axis II comorbidity is characterized by general (pervasive) pathology and by Cluster B PD pathology over and above the relationship to the general PD factor. Further, these relations between PD factors and substance dependence diagnoses appeared to largely account for the comorbidity among substance dependence diagnoses in the younger but not older participants. Our findings suggest that a failure to consider the general PD factor, which we interpret as reflecting interpersonal dysfunction, can lead to potential mischaracterizations of the nature of certain PD and SUD comorbidities.

[Is the term "dependence" appropriate?].
Pavlovský, P
1996-05-01
The term dependence is found in the International Classification of Diseases-10 only in conjunction with the diagnosis of a dependent personality disorder and the substance-related syndrome. Nowhere dependence not related to a substance is mentioned. At present we encounter in the press and professional literature frequently comments on dependence in relation to gambling, work, television, sports activities or some hobby. From the medical aspect it is a dominating idea, i.e. rather a phenomenon within the framework of an extended standard than a symptom from the field of psychopathology. The author recommends to avoid the use of the term "dependence not related to a substance" to prevent psychiatrization of common activities..

We examined associations between two definitions of sexual minority status (SMS) and substance abuse and/or dependence among young adults in a national population. A total of 14,152 respondents (7,529 women and 6,623 men) interviewed during wave four of the National Longitudinal Study of Adolescent Health were included in the study (age range: 24-32 years). We used two definitions of SMS based on self-reported attraction, behavior, and identity: 1-indicator SMS (endorsing any dimension) and 3-indicator SMS (endorsing all dimensions). Outcomes included nicotine dependence as well as ≥3 signs of substance dependence, any sign of substance abuse, and lifetime diagnosis of abuse or dependence for alcohol, marijuana, and a composite measure of other drugs. Weighted logistic regression models were fit to estimate the odds of each outcome for each of the sexual minority groups (compared with the heterosexual majority), controlling for sociodemographic covariates. SMS women were more likely than exclusively heterosexual women to experience substance abuse and dependence, regardless of substance or SMS definition. In adjusted models for women, 3-indicator SMS was most strongly associated with abuse/dependence (adjusted odds ratio [AOR] range: 2.74-5.17) except for ≥3 signs of cannabis dependence, where 1-indicator SMS had the strongest association (AOR=3.35). For men, the 1-indicator SMS group had higher odds of nicotine dependence (AOR=1.35) and the 3-indicator SMS group had higher odds of ≥3 signs of alcohol dependence (AOR=1.64). Young adult female sexual minority groups, regardless of how defined, are at a higher risk than their heterosexual peers of developing alcohol, drug, or tobacco abuse and dependence.

Numerous prospective studies have shown that children diagnosed with ADHD are at higher risk of long-term substance abuse/dependence. However, there are two important limits to these studies: a) most did not differentiate the role of hyperactivity and inattention; b) most did not control for associated behavioral problems; c) most did not consider females. Our aim was to clarify the unique and interactive contributions of childhood inattention and hyperactivity symptoms to early adulthood substance abuse/dependence. Behavioral problems of 1804 participants (814 males) in a population-based longitudinal study were assessed yearly between 6 and 12 years by mothers and teachers. The prevalence of substance abuse/dependence at age 21 years was 30.7% for nicotine, 13.4% for alcohol, 9.1 % for cannabis and 2.0% for cocaine. The significant predictors of nicotine dependence were inattention (OR: 2.25; 95% CI: 1.63–3.11) and opposition (OR: 1.65; 95%: 1.20–2.28). Only opposition contributed to the prediction of cannabis dependence (OR: 2.33; 95% CI: 1.40–3.87) and cocaine dependence (OR: 2.97; 95% CI: 1.06–8.57). The best behavioral predictor of alcohol abuse/dependence (opposition) was only marginally significant (OR: 1.38; 95% CI: 0.98–1.95). Frequent oppositional behaviors during elementary school were clearly the most pervasive predictors of substance abuse/dependence in early adulthood. The association of childhood ADHD with substance abuse/dependence is largely attributable to its association with opposition problems during childhood. However, inattention remained a key predictor of nicotine dependence, in line with genetic and molecular commonalities between the two phenotypes suggested in the literature. PMID:22733124

This review summarizes the history of the development of diagnostic constructs that apply to repetitive substance use, and compares and contrasts the nature, psychometric performance and utility of the major diagnoses in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD) diagnostic systems. The available literature was reviewed with a particular focus on diagnostic concepts that are relevant for clinical and epidemiological practice, and so that research questions could be generated that might inform the development of the next generation of DSM and ICD diagnoses. The substance dependence syndrome is a psychometrically robust and clinically useful construct, which applies to a range of psychoactive substances. The differences between the DSM fourth edition (DSM-IV) and the ICD tenth edition (ICD-10) versions are minimal and could be resolved. DSM-IV substance abuse performs moderately well but, being defined essentially by social criteria, may be culture-dependent. ICD-10 harmful substance use performs poorly as a diagnostic entity. There are good prospects for resolving many of the differences between the DSM and ICD systems. A new non-dependence diagnosis is required. There would also be advantages in a subthreshold diagnosis of hazardous or risky substance use being incorporated into the two systems. Biomedical research can be drawn upon to define a psychophysiological 'driving force' which could underpin a broad spectrum of substance use disorders.

Although the association between acculturation and substance use among Latino groups is important, it is often understudied, especially within specific Latino groups living in geographically distinct communities, such as the Mexican American population in South Texas. The researchers of this study aimed to better understand the effect of acculturation on substance use and alcohol dependence in a Mexican American college student population. This survey study investigated the correlation between acculturation and substance use and dependence by using the Vancouver Index of Acculturation (VIA), items related to substance use (nicotine, marijuana, and cocaine) in a Mexican American college student sample (N = 1,494), and the Short Alcohol Dependence Data Questionnaire (SADD; N = 715). The study was conducted in the Texas-Mexico border region. The results suggest that higher levels of acculturation do not predict increased drug use or alcohol dependence in the Mexican American college students. However, acculturation was found to be associated with lower use of cocaine and marijuana. The discussion examines commonalities and differences in drug use and dependence. Specifically, acculturation seems to have an inverse relationship to substance use and may serve as a protective factor to licit and illicit drug use among Mexican American college students.

Neuropyschological dysfunction, ranging from mild cerebral indicators to dementia has been a consistent part of the medical picture of HIV/AIDS. However, advances in medical supervision, particularly as a result of antiretroviral (ARV) treatment, have resulted in some mitigation of the neuropsychological effects of HIV and necessitate re-evaluation of the pattern and nature of HIV-related cognitive or mental deficits. The associated enhancements in morbidity and mortality that have occurred as a result of ARV medication have led to a need for interventions and programs that maintain behaviors that are healthy and stop the resurgence of the risk of HIV transmission. Risk factors such as mental illness and substance use that may have contributed to the initial infection with HIV still need consideration. These risk factors may also increase neuropsychological dysfunction and impact observance of prevention for treatment and recommendations. Explicitly, a better comprehension of the role of substance use on the progression of HIV-related mental decline can enlighten management and evaluation of persons living with HIV with concurrent disorders of substance use. This review provides a summary of the neurophyschology of substance use and HIV and the existing research that has looked at the effects of both substance use and HIV disease on neurophyscological function and suggestions for future research and treatment.

Incarcerated women have high rates of substance abuse problems and trauma. A variety of variables may influence whether these women seek help or are referred for substance abuse problems. This study reports an exploratory project on service utilization among incarcerated substance-dependent women (N = 40) in southeastern Idaho. Using self-report and interview tools, most participants reported some substance abuse treatment history, although extent and types of treatment varied. Most of the women also reported some type of childhood abuse. Age, income, and consequences of alcohol and other drug use related positively to substance abuse treatment. However, severity of childhood sexual abuse and current trauma symptoms were negatively correlated with substance abuse treatment episodes. These women may use substances to cope with childhood trauma or may not perceive the substance abuse system as responsive to their co-occurring trauma symptoms. Copyright © 2011 Elsevier Inc.

To examine the prevalence of use, abuse, and dependence on legal and illegal psychotropic substances in an adolescent in-patient psychiatric population in relation to age and gender. Participants were all consecutive admissions (patients aged from 14 to 17) to the adolescent psychiatric in-patient unit. Of the 86 patients who met all the criteria for taking part in the study 70 were interviewed, giving a response rate of 81%. Prevalence of use and of substance use disorders were assessed through structured diagnostic interviews (M-CIDI), conducted from March 2000 through July 2000. We found high prevalence of use and of the diagnosis of legal and illegal psychotropic substances. Around 76% reported a regular use of tobacco, 44% regular alcohol use, and 40% regular use of illegal substances. Diagnosis (abuse or dependence) was found in 50% of cases for nicotine, 29% for alcohol, and 26% for illegal substances. The adolescent in-patient psychiatric population is at high risk of use, abuse, and dependence on legal and illegal psychotropic substances. It is important to diagnose these disorders (anamnesis, screening tools) and to install preventive and therapeutic programs in clinical therapeutic settings.

This study explores whether associations between anxiety and alcohol and other substance use are already evident in middle adolescence, and whether general anxiety or symptoms of social phobia affect continuity of frequent alcohol use, frequent drunkenness and cannabis use. Data from the Adolescent Mental Health Cohort Study, a school-based Finnish survey among adolescents aged 15-16 years at baseline, was utilized to assess prevalence, incidence and continuity of symptoms of social phobia, general anxiety, frequent alcohol use, frequent drunkenness and cannabis use (which in this context was smoked 'hashish' of unknown constituency), and the associations between the substance use variables and the anxiety variables in 2-year follow-up. Anxiety preceded substance use while no reciprocal associations were observed. Depression mediated the associations between anxiety and substance use. Symptoms of social phobia did not elevate the incidence of substance use, but general anxiety did. Frequent drunkenness was less significantly associated with anxiety than the other two substance use variables. Co-morbid general anxiety increased the persistence of frequent alcohol use while co-morbid social phobia decreased its persistence. Continuity of frequent drunkenness and cannabis use were unaffected by co-morbid anxiety. General anxiety in middle adolescence places adolescents at risk for concurrent and subsequent substance use. The risk may, however, be associated with co-morbid depression. Social phobia in middle adolescence may protect from substance use. Adolescents with internalizing symptoms may need guidance in coping with the symptoms even if the symptoms do not fulfil the criteria of mood or anxiety disorder.

Harm reduction approaches endeavor to assist individuals with avoiding the most detrimental consequences of risk taking behaviors, but limited research has documented the outcomes of harm reduction substance abuse treatment. In total, 211 methamphetamine-using men who have sex with men (MSM) enrolled in two outcome studies of substance abuse treatment programs that were implementing an evidence-based, cognitive-behavioral intervention (i.e., the Matrix Model) from a harm reduction perspective. Study 1 (N = 123) examined changes in self-reported substance use, Addiction Severity Index (ASI) composite scores, and HIV care indicators over a 12-month follow-up. Study 2 (N = 88) assessed changes in substance use, sexual risk taking, and HIV care indicators over a 6-month follow-up. Participants in study 1 reported reductions in cocaine/crack use as well as decreases in the ASI drug and employment composite scores. Among HIV-positive participants in study 1 (n = 75), 47 % initiated or consistently utilized anti-retroviral therapy and this was paralleled by significant increases in self-reported undetectable HIV viral load. Study 2 participants reported reductions in methamphetamine use, erectile dysfunction medication use in combination with other substances, and sexual risk-taking behavior while using methamphetamine. Participants in both studies reported concurrent increases in marijuana use. Taken together, these studies are among the first to observe that clients may reduce stimulant use and concomitant sexual risk-taking behavior during harm reduction substance abuse treatment. Randomized controlled trials are needed to examine the differential effectiveness of harm reduction and abstinence-based approaches to substance abuse treatment.

Concurrent use of cigarettes with alternative tobacco products (ATPs), even among very light smokers, may be harmful. This study examined current use of e-cigarettes, cigars, and hookah, and susceptibility to future use of these products in a sample of college student cigarette smokers. Participants were 1161 18-29 year old (M age = 21.15; SD = 2.72; 52.7% female; 41.2% non-Hispanic white) current, or past 30-day cigarette smokers, drawn from a larger study. Current smokers were categorized as very light smokers [≤5 cigarettes per day (cpd)] and heavier smokers (>5 cpd). 88.6% of all participating college student smokers were very light smokers and 67.7% used at least one ATP concurrently. The prevalence of current use in this sample was 42.9% for e-cigarettes, 36.4% for hookah, and 25.9% for cigars. Compared to heavier smokers, very light smokers were more likely to be younger, racial/ethnic minorities, and four-year versus two-year college students. Multilevel logistic regression models showed that after controlling for socio-demographic characteristics and substance use, being a very light smoker, compared with a heavier smoker, was negatively associated with concurrent e-cigarette use, but positively associated with concurrent cigar use, and not associated with concurrent hookah use. Moreover, compared to heavier smokers, very light smokers reported being more susceptible to future cigar and hookah use, but not e-cigarette use. Concurrent use of cigarettes with ATPs is popular among all college student smokers, but very light smokers are more likely than heavier smokers to use combustible ATPs. Smoking intervention programs and campus policies should caution smokers, especially very light smokers, against ATP use. Copyright © 2018 Elsevier Ltd. All rights reserved.

The current study evaluates a therapy for substance-dependent perpetrators of partner violence. Sixty-three males arrested for partner violence within the past year were randomized to a cognitive behavioral substance abuse-domestic violence (SADV; n = 29) or a drug counseling (DC; n = 34) condition. Seventy percent of offenders completed eight core sessions with no differences between SADV and DC conditions in the amount of substance or aggression at pretreatment. SADV participants had fewer cocaine-positive toxicology screens and breathalyzer results during treatment, were less likely to engage in aggressive behavior proximal to a drinking episode, and reported fewer episodes of violence than DC participants at posttreatment follow-up. SADV shows promise in decreasing addiction and partner violence among substance-dependent male offenders. © 2017 American Association for Marriage and Family Therapy.
Physician substance use by medical specialty.

Self-reported past year use of alcohol, tobacco, marijuana, cocaine, and two controlled prescription substances (opiates, benzodiazepines); and self-reported lifetime substance abuse or dependence was estimated and compared for 12 specialties among 5,426 physicians participating in an anonymous mailed survey. Logistic regression models controlled for demographic and other characteristics that might explain observed specialty differences. Emergency medicine physicians used more illicit drugs. Psychiatrists used more benzodiazepines. Comparatively, pediatricians had overall low rates of use, as did surgeons, except for tobacco smoking. Anesthesiologists had higher use only for major opiates. Self-reported substance abuse and dependence were at highest levels among psychiatrists and emergency physicians, and lowest among surgeons. With evidence from studies such as this one, a specialty can organize prevention programs to address patterns of substance use specific to that specialty, the specialty characteristics of its members, and their unique practice environments that may contribute risk of substance abuse and dependence.
Substance use in adulthood following adolescent self-harm: a population-based cohort study

Objective To determine whether adolescents who self-harm are at increased risk of heavy and dependent substance use in adulthood. Method Fifteen-year prospective cohort study of a random sample of 1943 adolescents recruited from secondary schools across the state of Victoria, Australia. Data pertaining to self-harm and substance use was obtained at seven waves of follow-up, from mean age 15.9 years to mean age 29.1 years. Results Substance use and self-harm were strongly associated during the adolescent years (odds ratio (OR): 3.3, 95% CI 2.1–5.0). Moreover, adolescent self-harmers were at increased risk of substance use and dependence syndromes in young adulthood. Self-harm predicted a four-fold increase in the odds of multiple dependence syndromes (sex- and wave-adjusted OR: 4.2, 95% CI: 2.7–6.6). Adjustment for adolescent anxiety/depression attenuated but did not eliminate most associations. Adolescent substance use confounded all associations, with the exception of multiple dependence syndromes, which remained robustly associated with adolescent self-harm (fully adjusted odds ratio: 2.0, 95% CI: 1.2–3.2). Conclusion Adolescent self-harm is an independent risk factor for multiple dependence syndromes in adulthood. This level of substance misuse is likely to contribute substantially to the premature mortality and disease burden experienced by individuals who self-harm. PMID:24954250

To investigate all suicide cases that occurred in New Brunswick in the 14 months spanning April 1, 2002, to May 31, 2003, to determine 6-month and lifetime prevalence rates of psychopathology in the deceased. We used 2 psychological autopsy methods: direct proxy-based interviews and medical chart reviews, together with telephone contacts with informants. Consensus DSM-IV diagnoses were formulated by clinical panels on the basis of the Structured Clinical Interviews I and II for DSM-IV complemented by medical charts. Of the 109 suicide deaths identified by the coroner at the time of the study, we were able to investigate 102. At time of death, 65% of the suicide victims had a mood disorder, 59% had a substance-related disorder, and 42% had concurrent mood and substance-related disorders. The lifetime prevalence of substance-related disorders among these suicide victims was 66%. Finally, 52% of the suicide victims presented with a personality disorder; one-half of these were of the cluster B type. Although treatment of depression has frequently been recognized as the focal point of clinically based suicide-prevention efforts, our results underscore substance-related disorders as a key dimension of completed suicide. Suicide-prevention programs should be designed to address this problem more directly.

The current study examined the prevalence and associations of a need for domestic violence services among child welfare-involved mothers and fathers with substance use disorders. Data were drawn from 2,231 child welfare-involved parents in Illinois with an identified substance use disorder. Approximately 42% of mothers and 33% of fathers with a substance use disorder had a concurrent need for domestic violence services. The sample was stratified by gender and logistic regression models were fit to determine the adjusted odds of an identified need for domestic violence services. For both mothers and fathers, the strongest association was an additional need for mental health services. Age, education status, alcohol use, marijuana use, and a reported history of physical violence victimization were also associated with a need for domestic violence services among mothers, while race, age, marital status, annual income, alcohol use, cocaine use, and a reported history of physical violence perpetration were associated with a need for domestic violence services among fathers. The findings of this study make clear that domestic violence is a commonly co-occurring service need for child welfare-involved parents with identified substance use disorders, and that associations with this need vary by gender.

Prenatal cocaine exposure (PCE) is associated with increased rates of illicit-substance use during adolescence. In addition, both PCE and illicit-substance use are associated with alterations in cortico-striato-limbic neurocircuitry, development of which is ongoing throughout adolescence. However, the relationship between illicit-substance use, PCE and functional neural responses has not previously been assessed concurrently. Sixty-eight adolescents were recruited from an ongoing longitudinal study of childhood and adolescent development. All participants had been followed since birth. Functional magnetic resonance imaging (fMRI) data were acquired during presentation of personalized stressful, favorite-food and neutral/relaxing imagery scripts and compared between 46 PCE and 22 non-prenatally-drug-exposed (NDE) adolescents with and without lifetime illicit-substance use initiation. Data were analyzed using multi-level ANOVAs (pFWE<.05). There was a significant three-way interaction between illicit-substance use, PCE status and cue condition on neural responses within primarily cortical brain regions, including regions of the left and right insula. Among PCE versus NDE adolescents, illicit-substance use was associated with decreased subcortical and increased cortical activity during the favorite-food condition, whereas the opposite pattern of activation was observed during the neutral/relaxing condition. Among PCE versus NDE adolescents, illicit-substance use during stress processing was associated with decreased activity in cortical and subcortical regions including amygdala, hippocampus and prefrontal cortex. Neural activity within cortico-striato-limbic regions was significantly negatively associated with subjective ratings of anxiety and craving among illicit-substance users, but not among non-users. These findings suggest different neural substrates of experimentation with illicit drugs between adolescents with and without in utero cocaine exposure. Copyright © 2015 Elsevier Ireland Ltd.

Background Labour market disengagement among youths has lasting negative economic and social consequences, yet is poorly understood. We compared four types of work-related self-perceptions, as well as vulnerability to mental health and substance abuse problems, among youths not in education, employment, or training (NEET) and among their peers. Methods Participants were from the Environmental Risk (E-Risk) longitudinal study, a nationally representative U.K. cohort of 2,232 twins born in 1994–95. We measured commitment to work, job-search effort, professional/technical skills, “soft” skills (e.g., teamwork, decision-making, communication), optimism about getting ahead, and mental health and substance-use disorders at age 18. We also examined childhood mental health. Results At age 18, 11.6% of participants were NEET. NEET participants reported themselves as committed to work and searching for jobs with greater diligence than their non-NEET peers. However, they reported fewer “soft” skills (B = −0.98, p < .001) and felt less optimistic about their likelihood of getting ahead in life (B = −2.41, p < .001). NEET youths also had higher rates of concurrent mental health and substance-abuse problems, but these did not explain the relationship with work-related self-perceptions. Nearly 60% of NEET (vs. 35% of non-NEET) youths had already experienced ≥1 mental health problem in childhood/adolescence. Associations of NEET status with concurrent mental health problems were independent of pre-existing mental health vulnerability. Conclusions Our findings indicate that while NEET is clearly an economic and mental health issue, it does not appear to be a motivation issue. Alongside skills, work-related self-perceptions and mental-health problems may be targets for intervention and service provision among this high-risk population. PMID:26791344

The aims of this study were to examine evidence for the concurrent validity of two self-report measures and two staff-report measures measuring alcohol and drug problems in seriously mentally ill people and to examine if psychotic patients under-report their alcohol and drug problems in an early intervention clinic. This is a cross-sectional study of 48 patients (26 inpatients and 22 outpatients) from an early intervention clinic for psychosis. To examine the sensitivity and specificity, we compared both the staff-report measures Clinical Alcohol Use Scale (AUS) and Clinical Drug Use Scale (DUS) and the self-report measures Short Michigan Alcohol Screening Test (SMAST-13) and Drug Abuse Screening Test (DAST-20), with the current ICD-10 diagnostic criteria as the gold-standard for alcohol and drug problems. To examine whether the patients under-report their alcohol and drug problems, we also compared the self-report measures SMAST-13 and DAST-20 with the staff-report measures AUS and DUS and ICD-10 consensus substance abuse diagnoses. The results show that the concurrent validity compared with ICD-10 diagnoses was moderate for both the staff-report measures AUS and DUS and for the self-report measures SMAST-13 and DAST-20. Three out of seven patients under-report alcohol problems and one patient out of seven under-report drug use problems according to consensus ICD-10 substance abuse diagnoses. We conclude that the SMAST-13 and DAST-20 in combination with the AUS and DUS, which are easy and quick to perform, are helpful in establishing a common understanding of the patient's alcohol and drug problems in an early intervention clinic.

HIV+ individuals with and without substance use disorders make significantly poorer decisions when information about the probability and magnitude of wins and losses is not available. We administered the Game of Dice Task, a measure of decision making under risk that provides this information explicitly, to 92 HIV+ and 134 HIV- substance-dependent men and women. HIV+ participants made significantly poorer decisions than HIV- participants, but this deficit appeared more prominent among HIV+ women. These data indicate that decision making under risk is impaired among HIV+ substance-dependent individuals (SDIs). Potential factors for the HIV+ women's relatively greater impairment are discussed.

We investigated the link between child maltreatment, including child sexual assault (CSA) and child physical assault (CPA), and addiction-related symptomatology in a subsample of adolescents from the National Survey of Adolescents, all of whom met DSM-IV criteria for substance abuse or dependence (n=281). Over 60% of the sample reported a history of CSA and/or CPA. Results indicated significant differences in typography of substance abuse and dependence symptoms and rates of comorbid lifetime PTSD based on assault history, specific assault incident characteristics, and sex. Clinical implications for substance abusing youth with maltreatment histories are discussed. PMID:20151043

Racial disparity: substance dependency and psychological health problems among welfare recipients.
Lee, Kyoung Hag; Hines, Lisa D
2014-01-01
This study explored the racial disparity of substance dependency and psychological health among White, African American, and Hispanic Temporary Assistance to Needy Families (TANF) recipients as well as the relationship between substance dependency and psychological health. It analyzed 1,286 TANF recipients from the 2006 National Survey on Drug Use and Health data. Analysis of variance indicated that Whites were experiencing more nicotine and alcohol dependency and psychological distress than others, but African Americans and Hispanics were experiencing more cocaine dependency than Whites. Ordinary least squares regression revealed that nicotine dependency is significantly related to the psychological distress of Whites. Alcohol dependency is significantly associated with the psychological distress of three groups. Culturally competent programs are suggested.

Personality disorders (PDs) are considered to be potential predictors of treatment outcome in substance-dependent patients and potential treatment matching variables. There is a need for a brief and simple screening instrument for PDs that can be used in routine psychological assessment, especially in a treatment setting for previously substance-dependent criminal offenders, where a high prevalence of PDs is expected. This study investigated the psychometric properties of the Standardized Assessment of Personality-Abbreviated Scale (SAPAS), a commonly used screening interview for PDs, in a population of inpatient criminal offenders with a history of substance dependence. Various statistical procedures were used to establish reliability and validity measures, such as Kuder-Richardson 20, confirmative factor analysis, receiver operating characteristic analysis and multitrait multimethod matrix. The SAPAS was administered to 101 inpatient criminal offenders with a history of substance dependence at baseline. Within three weeks, participants were administered the Structured Interview for DSM-IV Personality in order to assess the presence of PDs. Results show limited evidence to make firm conclusions on the psychometric qualities of the SAPAS as a screening instrument for comorbid PDs in a substance dependence treatment setting for criminal offenders. Suggestions for improvement concerning the psychometric qualities of the SAPAS as a screening instrument for this population are noted. Copyright © 2012 John Wiley & Sons, Ltd.

Objective. We examined abstinence rates among substance-dependent women receiving Temporary Assistance for Needy Families (TANF) in intensive case management (ICM) over 24 months and whether ICM yielded significantly better employment outcomes compared with a screen-and-refer program (i.e., usual care). Methods. Substance-dependent (n = 302) and non–substance dependent (n = 150) TANF applicants in Essex County, New Jersey, were recruited. We randomly assigned substance-dependent women to ICM or usual care. We interviewed all women at 3, 9, 15, and 24 months. Results. Abstinence rates were higher for the ICM group than for the usual care group through 24 months of follow-up (odds ratio [OR] = 2.11; 95% confidence interval [CI] = 1.36, 3.29). A statistically significant interaction between time and group on number of days employed indicated that the rate of improvement over time in employment was greater for the ICM group than for the usual care group (incidence rate ratio = 1.03; 95% CI = 1.02, 1.04). Additionally, there were greater odds of being employed full time for those in the ICM group (OR = 1.68; 95% CI = 1.12, 2.51). Conclusions. ICM is a promising intervention for managing substance dependence among women receiving TANF and for improving employment rates among this vulnerable population. PMID:19059855

A structured interview and standardized rating scales were used to assess a sample of 194 outpatients with schizophrenia in a regional Australian mental health service for substance use, abuse, and dependence. Case manager assessments and urine drug screens were also used to determine substance use. Additional measurements included demographic information, history of criminal charges, symptom self-reports, personal hopefulness, and social support. The sample was predominantly male and showed relative instability in accommodations, and almost half had a history of criminal offenses, most frequently drug or alcohol related. The 6-month and lifetime prevalence of substance abuse or dependence was 26.8 and 59.8 percent, respectively, with alcohol, cannabis, and amphetamines being the most commonly abused substances. Current users of alcohol comprised 77.3 percent and current users of other nonprescribed substances (excluding tobacco and caffeine) comprised 29.9 percent of the sample. Rates of tobacco and caffeine consumption were high. There was a moderate degree of concordance between case manager determinations of a substance-use problem and research diagnoses. Subjects with current or lifetime diagnoses of substance abuse/dependence were predominantly young, single males with higher rates of criminal charges; however, there was no evidence of increased rates of suicide attempts, hospital admissions, or daily doses of antipsychotic drugs in these groups compared with subjects with no past or current diagnosis of substance abuse or dependence. Subjects with a current diagnosis of substance use were younger at first treatment and currently more symptomatic than those with no past or current substance use diagnosis. The picture emerging from this study replicates the high rate of substance abuse in persons with schizophrenia reported in North American studies but differs from the latter in finding a slightly different pattern of substances abused (i.e., absence of cocaine), reflecting relative differences in the availability of certain drugs.
Adolescent Alcoholism and Drug Addiction: The Experience of Parents.
Choate, Peter W
2015-10-29
Alcoholism and drug addiction have marked impacts on the ability of families to function. Much of the literature has been focused on adult members of a family who present with substance dependency. There is limited research into the effects of adolescent substance dependence on parenting and family functioning; little attention has been paid to the parents' experience. This qualitative study looks at the parental perspective as they attempted to adapt and cope with substance dependency in their teenage children. The research looks into family life and adds to family functioning knowledge when the identified client is a youth as opposed to an adult family member. Thirty-one adult caregivers of 21 teenagers were interviewed, resulting in eight significant themes: (1) finding out about the substance dependence problem; (2) experiences as the problems escalated; (3) looking for explanations other than substance dependence; (4) connecting to the parent's own history; (5) trying to cope; (6) challenges of getting help; (7) impact on siblings; and (8) choosing long-term rehabilitation. Implications of this research for clinical practice are discussed.
Addiction liability of pharmacotherapeutic interventions in obesity.
Greene, William M; Sylvester, Mark; Abraham, Joel
2011-01-01
Obesity and substance use disorders are rapidly growing problems throughout the world. Of the current mainstay therapies of diet, exercise, behavioral modification, surgery, and medications, drugs have the greatest risk for abuse and dependence. As each of these disorders share similar underpinnings mediated by the dopaminergic brain reward pathways, clinicians must seriously consider the safety of both the patient's physical and mental health when prescribing treatments. Specifically, balance and awareness of the factors involved in the variable abuse potentials of these prescribed medications is paramount. A cursory review of weight loss medications commonly used is performed with attention to FDA status, mechanism of action, and abuse potential. Concurrent strategies to minimize risk such as drug screening, ruling out doctor shopping, temporal considerations, monitoring for signs and symptoms of abuse and/or dependency, and a safety-tiered prescribing approach is also discussed in order to optimize best treatment practice. As the understanding of these disorders progresses along with the evolution of agreed nomenclature and awareness of compulsive behavioral disorders in general, greater safety and more appropriate interventions may be achieved. Further areas of research will help to elucidate nuances of the coocurrance and treatment of these disorders and perhaps guide drug research and development in the area of drug treatments of obesity.

To elucidate mechanisms of acute and chronic pain, it is important to understand how spinal excitatory systems influence opioid analgesia. The tachykinin substance P (SP) represents the prototypic spinal excitatory peptide neurotransmitter/neuromodulator, acting in concert with endogenous opioid systems to regulate analgesic responses to nociceptive stimuli. We have synthesized and pharmacologically characterized a chimeric peptide containing overlapping NH2- and COOH-terminal functional domains of the endogenous opioid endomorphin-2 (EM-2) and the tachykinin SP, respectively. Repeated administration of the chimeric molecule YPFFGLM-NH2, designated ESP7, into the rat spinal cord produces opioid-dependent analgesia without loss of potency over 5 days. In contrast, repeated administration of ESP7 with concurrent SP receptor (SPR) blockade results in a progressive loss of analgesic potency, consistent with the development of tolerance. Furthermore, tolerant animals completely regain opioid sensitivity after post hoc administration of ESP7 alone, suggesting that coactivation of SPRs is essential to maintaining opioid responsiveness. Radioligand binding and signaling assays, using recombinant receptors, confirm that ESP7 can coactivate μ-opioid receptors (MOR) and SPRs in vitro. We hypothesize that coincidental activation of the MOR- and SPR-expressing systems in the spinal cord mimics an ongoing state of reciprocal excitation and inhibition, which is normally encountered in nociceptive processing. Due to the ability of ESP7 to interact with both MOR and SPRs, it represents a unique prototypic, anti-tolerance-forming analgesic with future therapeutic potential. PMID:10852965

The present study aimed to identify proximal and distal factors associated with real life community functioning among men with schizophrenia. Real life community functioning was defined to include: independent living, occupational functioning, social and leisure activities, and substance misuse, self-harm, and aggressive behaviour. 225 men with schizophrenia or schizo-affective disorder were assessed at discharge from hospital and at six-monthly intervals during a two-year period. Information was available from structured interviews with the participants, family members and treatment staff, records of psychiatric treatment, social service files, and official criminal records. Symptoms were assessed using the Positive and Negative Symptom Scale and the Hamilton Rating Scale for Depression. Substance misuse was measured by self-report and hair and urine analyses. Predictors of outcome were divided into four categories: childhood, adulthood, year prior to functional outcome assessment, and con-current. In a final regression model, five predictors were significantly associated with patients' real life functioning: two adult life-time variables-a diagnosis of drug abuse/dependence and level of education and three current variables-victimisation, depression, and medication non-compliance. Most of the variance in the final outcome scores was explained by current predictors. In order to elevate levels of psychosocial functioning among men with schizophrenia, clinicians need to assess victimisation experiences, and, when present, design and implement interventions to help patients protect themselves. In addition, depression needs to be identified and treated, and compliance with antipsychotic medication assured.

Objective To describe inpatient hospitalization patterns among detained and non-detained youth in a large, total population of hospitalized adolescents in California. Methods We examined the unmasked California Office of Statewide Health Planning and Development Patient Discharge Dataset from 1997-2011. We considered hospitalized youth aged 11-18 years “detained” if admitted to California hospitals from detention, transferred from hospital to detention, or both. We compared discharge diagnoses and length of stay (LOS) between detained youth and their non-detained counterparts in the general population. Results There were 11,367 hospitalizations for detained youth. Hospitalizations differed for detained versus non-detained youth: 63% of all detained youth had a primary diagnosis of mental health disorder (compared to 19.8% of non-detained youth). Detained girls were disproportionately affected, with 74% hospitalized for a primary mental health diagnosis. Detained youth hospitalized for mental health disorder had an increased median LOS compared to non-detained inpatient youth with mental illness (≥6 days versus 5 days, respectively). This group difference was heightened in the presence of minority status, public insurance, and concurrent substance abuse. Hospitalized detained youth discharged to chemical dependency treatment facilities had the longest hospital stays (≥43 days). Conclusions Detained juvenile offenders are hospitalized for very different reasons than the general adolescent population. Mental illness, often with comorbid substance abuse, requiring long inpatient stays, represents the major cause for hospitalization. These findings underscore the urgent need for effective, well-coordinated mental health services for youth before, during, and after detention. PMID:26208862

Prenatal exposures to alcohol, cigarettes, and other drugs of abuse are associated with numerous adverse consequences for affected offspring, including increased risk for substance use and abuse. However, maternal substance use during pregnancy appears to occur more often in those with a family history of alcohol dependence. Utilizing a sample that is enriched for familial alcohol dependence and includes controls selected for virtual absence of familial alcohol dependence could provide important information on the relative contribution of familial risk and prenatal exposures to offspring substance use. A sample of multigenerational families specifically ascertained to be at either high or low risk for developing alcohol dependence (AD) provided biological offspring for a longitudinal prospective study. High-risk families were selected based on the presence of 2 alcohol-dependent sisters. Low-risk families were selected on the basis of minimal first and second-degree relatives with AD. High-risk (HR = 99) and Low-risk offspring (LR = 110) were assessed annually during childhood and biennially in young adulthood regarding their alcohol, drug, and cigarette use. At the first childhood visit, mothers were interviewed concerning their prenatal use of substances. High-risk mothers were more likely to use alcohol, cigarettes, and other drugs during pregnancy than low-risk control mothers, and to consume these substances in greater quantities. Across the sample, prenatal exposure to alcohol was associated with increased risk for both offspring cigarette use and substance use disorders (SUD), and prenatal cigarette exposure was associated with increased risk for offspring cigarette use. Controlling for risk status by examining patterns within the HR sample, prenatal cigarette exposure remained a specific predictor of offspring cigarette use, and prenatal alcohol exposure was specifically associated with increased risk for offspring SUD. Women with a family history of SUD are at increased risk for substance use during pregnancy. Both familial loading for alcohol dependence and prenatal exposure to alcohol or cigarettes are important risk factors in the development of offspring substance use. An inadequate assessment of family history may obscure important interactions between familial risk and prenatal exposures on offspring outcomes.

Background The current prevalence rate of substance abuse and dependence, represents an increasing trend of substance abuse and dependence among women, and the results of epidemiology studies indicate that substance use patterns are different between men and women. This study aimed to determine gender differences in substance use patterns and disorders among the patients undergoing methadone maintenance treatment. Methods This cross-sectional study was conducted throughout a specified time bracket ranging from September 2012 through March 2013 in Methadone Maintenance Treatment (MMT) clinics of Mashhad, Iran. In this study, 140 men and 120 women were selected from among the patients referring to MMT clinics in Mashhad through purposeful sampling method. The sample units were assessed using a demographic information questionnaire and Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID). The data were then analyzed by Chi Square test, Mann-Whitney U test, and Independent-samples t-test. SPSS software 16 was used to conduct statistical analyses with P values less than 0.05 regarded as significant. Results The results showed that men and women are significantly different from each other in terms of marital status (p=0.001), education (p=0.001), income (p=0.001), history of injection (p=0.002), imprisonment (p=0.001), and substance use abstention (p=0.023). It was also revealed that methamphetamine dependence (p=0.017) and simultaneous use of multiple substances (p=0.001) in the past 12 months were diagnosed, to a larger extent, in male participants than those in female participants. In addition, the diagnoses of nicotine dependence (p=0.001), cannabis abuse (p=0.001), heroin dependence (p=0.001), and substance abuse and alcohol dependence (p=0.001) during a lifetime were more frequently existing in males than those in females. Conclusion There are gender differences in substance use patterns and disorders that appear to be caused by the degree of access to substances and the impacts of cultural and social aspects on men and women in Iran.

Suicide and attempted suicide are common in individuals with schizophrenia, and evidence exists for a link between substance use disorders and suicidality in this disorder. However, alcohol has not been consistently implicated. We examined the relationship between substance use disorders and suicide attempts in schizophrenia. We recruited a schizophrenia sample in Australia (n = 821) for genetic analyses. We analysed demographic and clinical variables, including substance use disorders, and their relationship to suicide attempts using generalised equation modelling. A significant association was identified between lifetime alcohol abuse/dependence and suicide attempts (OR = 1.66; 95% CI, 1.23 to 2.24; p = 0.001) after adjustment for potential confounders, but not between cannabis abuse/dependence and suicide attempts, nor between other illicit drug abuse/dependence and suicide attempts. Polysubstance abuse/dependence was also not implicated. These results suggest that the presence of alcohol abuse/dependence may be a risk factor for suicide attempts in individuals with schizophrenia, independent of comorbid substance abuse/dependence.
An Effective Method for Substance Detection Using the Broad Spectrum THz Signal: A “Terahertz Nose”
Trofimov, Vyacheslav A.; Varentsova, Svetlana A.
2015-01-01
We propose an effective method for the detection and identification of dangerous substances by using the broadband THz pulse. This pulse excites, for example, many vibrational or rotational energy levels of molecules simultaneously. By analyzing the time-dependent spectrum of the THz pulse transmitted through or reflected from a substance, we follow the average response spectrum dynamics. Comparing the absorption and emission spectrum dynamics of a substance under analysis with the corresponding data for a standard substance, one can detect and identify the substance under real conditions taking into account the influence of packing material, water vapor and substance surface. For quality assessment of the standard substance detection in the signal under analysis, we propose time-dependent integral correlation criteria. Restrictions of usually used detection and identification methods, based on a comparison between the absorption frequencies of a substance under analysis and a standard substance, are demonstrated using a physical experiment with paper napkins.

Gene × environment interaction contributes to externalizing disorders in adolescence, but little is known about whether such effects are long-lasting or present in adulthood. We examined gene-environment interplay in the concurrent and prospective associations between antisocial peer affiliation and externalizing disorders (antisocial behavior and substance use disorders) at ages 17, 20, 24, and 29. The sample included 1,382 same-sex twin pairs participating in the Minnesota Twin Family Study. We detected a gene × environment interaction at age 17, such that additive genetic influences on antisocial behavior and substance use disorders were greater in the context of greater antisocial peer affiliation. This gene × environment interaction was not present for antisocial behavior symptoms after age 17, but was for substance use disorder symptoms through age 29 (though effect sizes were largest at age 17). Results suggest adolescence is a critical period for the development of externalizing disorders wherein exposure to greater environmental adversity is associated with a greater expression of genetic risk. This form of gene × environment interaction may persist through young adulthood for substance use disorders, but is limited to adolescence for antisocial behavior. PMID:27580681

This study aimed to investigate the correlations between early initiation (<12 years) of smoking cigarettes, alcohol use, and drug use (cannabis) with suicidal ideation and suicide attempts in school-aged adolescents in four Pacific Island countries in Oceania. The sample included 6540 adolescents (≤13 to ≥16 years old) from Kiribati, Samoa, Solomon Islands, and Vanuatu. Bivariate and multivariable analyses were conducted to assess the association between pre-adolescent substance use initiation and suicidal ideation and suicide attempts. Results indicate a prevalence of 25.8% suicidal ideation in the past 12 months (ranging from 17.2% in Vanuatu to 34.7% in Kiribati) and 34.9% suicide attempts in the past 12 months (ranging from 23.5% in Vanuatu to 62.0% in Samoa). The prevalence of early cigarette smoking initiation was 15.7%, early alcohol initiation 13.8%, and early drug use initiation was 12.9%. Students who reported pre-adolescent substance use initiation, compared with non-substance users, were more likely reporting suicidal ideation and suicide attempts. The concurrent initiation of cigarette smoking, alcohol, and drug use should be targeted in early prevention programmes in order to prevent possible subsequent suicidal behaviours.

Substance P containing nerves are widely distributed throughout the gastrointestinal tract. The aims of this study were to determine the distribution of substance P containing nerves in the extrahepatic biliary tree of the Australian brush-tailed possum and to characterize the effect of exogenous substance P on the sphincter of Oddi (SO) motility and transphincteric flow in vivo. Immunohistochemical staining of fixed specimens (n = 8) found moderate numbers of substance P containing nerve cell bodies and fibres throughout the neural plexuses of the SO, in particular in the serosal and intraluminal nerve trunks of the SO and gallbladder. Synthetic porcine substance P (1-2000 ng kg-1), administered by close intra-arterial injection (i.a.; n = 7), produced a dose-dependent elevation in basal pressure [P < 0.01] and an associated dose-dependent reduction in trans-sphincteric flow [P < 0.0001]. Substance P had no significant dose-dependent effect on SO phasic contraction amplitude or frequency. Tetrodotoxin (9 micrograms kg-1, i.a.) did not inhibit the effect of substance P on SO motility and trans-sphincteric flow (n = 5). In conclusion, substance P containing nerves are found throughout the possum extrahepatic biliary tree. Exogenous substance P stimulates SO motility and reduces trans-sphincteric flow in vivo by acting directly on the sphincter smooth muscle.

Since DSM-IV was published in 1994, its approach to substance use disorders has come under scrutiny. Strengths were identified (notably, reliability and validity of dependence), but concerns have also arisen. The DSM-5 Substance-Related Disorders Work Group considered these issues and recommended revisions for DSM-5. General concerns included whether to retain the division into two main disorders (dependence and abuse), whether substance use disorder criteria should be added or removed, and whether an appropriate substance use disorder severity indicator could be identified. Specific issues included possible addition of withdrawal syndromes for several substances, alignment of nicotine criteria with those for other substances, addition of biomarkers, and inclusion of nonsubstance, behavioral addictions. This article presents the major issues and evidence considered by the work group, which included literature reviews and extensive new data analyses. The work group recommendations for DSM-5 revisions included combining abuse and dependence criteria into a single substance use disorder based on consistent findings from over 200,000 study participants, dropping legal problems and adding craving as criteria, adding cannabis and caffeine withdrawal syndromes, aligning tobacco use disorder criteria with other substance use disorders, and moving gambling disorders to the chapter formerly reserved for substance-related disorders. The proposed changes overcome many problems, while further studies will be needed to address issues for which less data were available. PMID:23903334

OBJECTIVES: To determine the prevalence of drug and alcohol use among newly remanded prisoners, assess the effectiveness of prison reception screening, and examine the clinical management of substance misusers among remand prisoners. DESIGN: A consecutive case study of remand prisoners screened at reception for substance misuse and treatment needs and comparison of findings with those of prison reception screening and treatment provision. SETTING: A large adult male remand prison (Durham). SUBJECTS: 548 men aged 21 and over awaiting trial. MAIN OUTCOME MEASURES: Prevalence of substance misuse; treatment needs of substance misusers; effectiveness of prison reception screening for substance misuse; provision of detoxification programmes. RESULTS: Before remand 312 (57%) men were using illicit drugs and 181 (33%) met DSM-IV drug misuse or dependence criteria; 177 (32%) men met misuse or dependence criteria for alcohol. 391 (71%) men were judged to require help directed at their drug or alcohol use and 197 (36%) were judged to require a detoxification programme. The prison reception screen identified recent illicit drug use in 131 (24%) of 536 men and problem drinking in 103 (19%). Drug use was more likely to be identified by prison screening if an inmate was using multiple substances, using opiates, or had a diagnosis of abuse or dependence. 47 (9%) of 536 inmates were prescribed treatment to ease the symptoms of substance withdrawal. CONCLUSIONS: The prevalence of substance misuse in newly remanded prisoners is high. Prison reception health screening consistently underestimated drug and alcohol use. In many cases in which substance use is identified the quantities and numbers of different substances being used are underestimated. Initial management of inmates identified by prison screening as having problems with dependence producing substances is poor. Few receive a detoxification programme, so that many are left with the option of continuing to use drugs in prison or facing untreated withdrawal. PMID:9233320

Treatment providers need tools which are designed to identify risk, treatment needs, and monitor client engagement. These are essential components in substance abuse treatment for offender populations. This study evaluated a flexible set of 1-page modular assessments known as the TCU Short Forms and compared them with the measures of global domains contained in the Addiction Severity Index (ASI). The sample was based on 540 adult males and females in corrections-based substance abuse treatment services located in Arkansas and Missouri. Results suggest the set of TCU forms and ASI both reliably represent core clinical domains, but TCU Short Forms explained more variance in therapeutic engagement criteria measured during treatment. Similarities and differences of the assessment tools are discussed, along with applications PMID:23087588

Posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) are prevalent and frequently co-occur. Comorbid PTSD/SUD is associated with a more complex and costly clinical course when compared with either disorder alone, including increased chronic physical health problems, poorer social functioning, higher rates of suicide attempts, more legal problems, increased risk of violence, worse treatment adherence, and less improvement during treatment. In response, psychosocial treatment options have increased substantially over the past decade and integrated approaches – treatments that address symptoms of both PTSD and SUD concurrently –are fast becoming the preferred model for treatment. This paper reviews the prevalence, etiology and assessment practices as well as advances in the behavioral and pharmacologic treatment of comorbid PTSD and SUDs. PMID:24179316

The WHO World Mental Health (WMH) Survey Initiative uses the Composite International Diagnostic Interview (CIDI) for data collection and operationalizes diagnoses using DSM-IV criteria. The first 13 WMH surveys used CIDI version 3.0, which only assessed substance dependence among respondents with a history of substance abuse, while subsequent surveys also assessed substance dependence without symptoms of abuse. The aim of the current report is to compare results across the two sets of surveys to assess the implications of the revised skip logic and develop an imputation model for missing values of lifetime dependence without symptoms of abuse in the earlier surveys. Prevalence of lifetime dependence without symptoms of abuse was low in the second set of WMH surveys (0.3% for alcohol and 0.2% for drugs). Regression-based imputation models were built in random half-samples of the new surveys and validated in the other half-samples. There were minimal difference in the distributions of imputed and reported cases in the validation dataset for important correlates such as age, gender and quantity though higher numbers of additional mental disorders and number of days out of role were found in the imputed than reported cases. Concordance between imputed and observed estimates of total lifetime dependence in the full sample was high both for alcohol dependence (sensitivity 88.0%, specificity 99.8%, TCA 99.5% and AUC 0.94) and drug dependence (sensitivity 100.0%, specificity 99.8%, TCA 99.8% and AUC 1.00). This study provides cross-national evidence of the degree to which each of lifetime alcohol dependence and lifetime drug dependence occur without symptoms of abuse. Additionally imputation of substance dependence without symptoms of abuse in the earlier WMH surveys will result in improved estimates of lifetime prevalence for comparison with other epidemiological studies both cross-nationally and over time.

Background: Substance misuse is a matter of major public health concern in India. House-to-house survey, though an appealing method to generate population-level estimates, has limitations for estimating prevalence rates of use of illicit and rare substances. Materials and Methods: In this rapid assessment survey (RAS), respondent-driven sampling was used to recruit substance-using individuals from the field. Size of the substance-using population was estimated using the “benchmark-multiplier” method. This figure was then projected to the entire population of the Union Territory (U.T) of Chandigarh. Focused group discussions were used to study the perceptions and views of the substance users regarding various aspects of substance use. Results: Prevalence of any substance dependence in the U.T of Chandigarh was estimated to be 4.65%. Dependence rates on opioids, cannabinoids, and sedative hypnotics were found to be 1.53%, 0.52%, and 0.015%, respectively. Prevalence of injectable opioids was calculated to be 0.91%. Injectable buprenorphine was the most commonly used opioid, followed by bhukhi/doda/opium and heroin. A huge gap was found between the prevalence rates of substance-using population and those seeking treatment. Conclusion: RAS can be a useful method to determine the prevalence of illicit and rare substances. Our survey shows that the use of substance including that of opioids is highly prevalent in the U.T of Chandigarh. The findings of this survey can have implications for policymaking. PMID:29085086

The following study assesses the relationship between affiliating with delinquent peer groups, participation in delinquency, and several substance misuse and injecting drug use outcomes in a nationally representative sample of inmates in state and federal facilities in the United States. After controlling for potential confounders, affiliating with peers who engaged in deviant behaviors and participation in delinquency was associated with onset of alcohol and illicit drug use, substance dependence, alcohol dependence, types of substances used, and injecting drug use outcomes. Inmates who began engaging in delinquency at older ages reported initiating drug and alcohol use at older ages, and were less likely to meet the criteria for drug abuse or dependence, less likely to use substances daily or near daily, and less likely to report having ever injected or shared syringes. The implications of these findings for substance abuse, HIV, and crime prevention interventions are discussed. PMID:28966393

Recent theories suggest that behavioural addictions and substance use disorders may be the result of the same underlying vulnerability. The present study investigates profiles of family background, personality and mental health factors and their associations with seven behavioural addictions (to the internet, gaming, smartphones, internet sex, gambling, exercise and work) and three substance use disorder scales (for alcohol, cannabis and tobacco). The sample consisted of 5287 young Swiss men (mean age = 25.42) from the Cohort Study on Substance Use Risk Factors (C-SURF). A latent profile analysis was performed on family background, personality and mental health factors. The derived profiles were compared with regards to means and prevalence rates of the behavioural addiction and substance use disorder scales. Seven latent profiles were identified, ranging from profiles with a positive family background, favourable personality patterns and low values on mental health scales to profiles with a negative family background, unfavourable personality pattern and high values on mental health scales. Addiction scale means, corresponding prevalence rates and the number of concurrent addictions were highest in profiles with high values on mental health scales and a personality pattern dominated by neuroticism. Overall, behavioural addictions and substance use disorders showed similar patterns across latent profiles. Patterns of family background, personality and mental health factors were associated with different levels of vulnerability to addictions. Behavioural addictions and substance use disorders may thus be the result of the same underlying vulnerabilities. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Electrophysiological and mechanical effects of substance P and acetylcholine on rabbit aorta.
Bény, J L; Brunet, P C

1. The mechanical and electrical properties of smooth muscle cells of the rabbit aorta were recorded simultaneously using respectively a force transducer and a 3 M-KCl-filled glass microelectrode. 2. Acetylcholine had two effects depending on concentration. At low concentration, it caused a persistent endothelium-dependent relaxation and hyperpolarization. At higher concentrations the acetylcholine endothelium-dependent relaxation summed with an endothelium-independent contraction. 3. Substance P caused a transient endothelium-dependent relaxation and hyperpolarization. 4. Acetylcholine and substance P depolarized and contracted de-endothelialized smooth muscle. When the de-endothelialized strip was pre-contracted by noradrenaline, acetylcholine depolarized the muscle but substance P did not. 5. In a 'cascade' experiment, the perfusate from an upstream intact aorta passed over a downstream de-endothelialized strip. Acetylcholine and substance P relaxed the downstream strip showing that they released an endothelial humoral factor which relaxes smooth muscle. 6. The results suggest a constant release of a factor from the endothelial cells which hyperpolarizes the smooth muscle cells in the media. Activation of acetylcholine and substance P receptors on the endothelium accelerates the release of this factor and causes vasodilatation. PMID:2455799

Aims The objective of this study was to examine the associations between compulsive buying (CB) and substance dependence/abuse, major depressive episode (MDE), and generalized anxiety disorder (GAD) at mean age 43. Methods Participants came from a community-based random sample of residents in two New York counties (N=548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (SD=2.8). Fifty five percent of the participants were females. Over 90% of the participants were white. The prevalence of substance dependence/abuse, MDE, and GAD (during the past 5 years before the interviews) was 6.6%, 13.7, and 11.5%, respectively. Results Logistic regression analyses showed that CB was significantly associated with substance dependence/abuse [Adjusted Odds Ratio (A.O.R.) = 1.60], MDE (A.O.R. = 1.70), and GAD (A.O.R. = 1.63), despite controlling for substance dependence/abuse, MDE, and GAD, respectively, at mean age 37, and demographic factors. Discussion Since the study sample is limited to predominantly white participants (over 90%) with a close association to a small geographic area, the findings may not be generalizable to racial/ethnic minority groups or individuals living in other parts of the country. Nevertheless, it is important that clinicians treating substance dependence/abuse, MDE, and GAD consider the role of CB. PMID:27215919

There is a growing body of research demonstrating that families of individuals with substance use and concurrent disorders (SUCD) experience a wide range of biopsychosocial problems that significantly impedes their quality of life and health. However, there has been a relative lack of treatment programs primarily focused on improving the well-being and quality of life of these family members. The current study assessed the efficacy of such a program at reducing stress, increasing perceived social support from family and friends, and increasing general, dyadic, and self-rated family functioning within these concerned family members. A sample of 125 family members of individuals with SUCDs was recruited, of which 97 participated in the treatment program and 28 were used as the comparison group. Results indicated that the treatment program significantly reduced stress, increased perceived social support from family and friends, and increased general, dyadic and self-rated family functioning. A perceived personal benefits questionnaire demonstrated that participants had a better understanding of SUCDs, better coping capabilities in regard to emotional difficulties, adopted stronger coping methods, participated in more leisure activities, and improved their relationship with the individual with a SUCD. The results of the current study further demonstrate the need to implement more of these family-member oriented psycho-educational treatment programs. Copyright © 2017 Elsevier Inc.

To investigate the role of personality factors and attentional biases towards emotional faces, in establishing concurrent and prospective risk for mental disorder diagnosis in adolescence. Data were obtained as part of the IMAGEN study, conducted across 8 European sites, with a community sample of 2257 adolescents. At 14 years, participants completed an emotional variant of the dot-probe task, as well two personality measures, namely the Substance Use Risk Profile Scale and the revised NEO Personality Inventory. At 14 and 16 years, participants and their parents were interviewed to determine symptoms of mental disorders. Personality traits were general and specific risk indicators for mental disorders at 14 years. Increased specificity was obtained when investigating the likelihood of mental disorders over a 2-year period, with the Substance Use Risk Profile Scale showing incremental validity over the NEO Personality Inventory. Attentional biases to emotional faces did not characterise or predict mental disorders examined in the current sample. Personality traits can indicate concurrent and prospective risk for mental disorders in a community youth sample, and identify at-risk youth beyond the impact of baseline symptoms. This study does not support the hypothesis that attentional biases mediate the relationship between personality and psychopathology in a community sample. Task and sample characteristics that contribute to differing results among studies are discussed.

Many college students are using substances at levels consistent with Substance Abuse or Dependence, yet little explanation for this phenomenon exits. The aim of this study was to explore a risk factor profile that best separates those with low and high potential for having a substance use disorder (SUD). A discriminant function analysis revealed that participants with a high probability of having a SUD misperceive others' alcohol and marijuana use to a greater extent than those with a low probability of having a SUD. Implications for educators and counselors on college campuses are discussed.

The purpose of this study was to obtain information about education in substance use and dependence that appears in the predoctoral curricula of U.S. and Canadian dental schools. Sixty-eight deans were sent a twenty-item survey requesting information about when in the curriculum these subjects were taught, what instructional methods were used, and whether behavior change instruction was included to address these issues in clinical interactions. The survey had an 81 percent response rate. The topics of alcohol use and dependence, tobacco use and dependence, and prescription drug misuse and abuse were reported in over 90 percent (N=55) of responding schools’ predoctoral curricula. The topic of other substance use and dependence was reported in only 72.7 percent (N=40) of these schools. The primary instructional method reported was the use of lecture. Less frequently used methods included small-group instruction, instruction in school-based clinic, community-based extramural settings, and independent study. As future health professionals, dental students are an important source for patients concerning substance use, abuse, and treatment. Our investigation confirmed that alcohol, tobacco, and prescription drug abuse is addressed widely in predoctoral dental curricula, but other substance use and dependence are less frequently addressed.

Injectable extended-release naltrexone (XRNTX) presents an effective therapeutic strategy for opioid addiction, however its utility could be hampered by poor adherence. To gain a better insight into this phenomenon, we utilized blood oxygenation level-dependent functional magnetic resonance imaging (fMRI) in conjunction with a validated cue-induced craving procedure to examine neural correlates of XRNTX adherence. We operationalized treatment adherence as the number of monthly XRNTX injections (range: 0–3) administered to a group of fully detoxified heroin-dependent subjects (n=32). Additional outcomes included urine toxicology screening and self-reported tobacco use. The presented heroin-related visual cues reliably elicited heroin craving in all tested subjects. Nine, five, three and 15 of the participants, respectively, received zero, one, two and three XRNTX injections, predicted by the individual baseline fMRI signal change in response to the cues in the medial prefrontal cortex, a brain region involved in inhibitory self-control and emotional appraisal. The incidence of opioid-positive urines during the XRNTX therapy was low and remained about half the pre-treatment rate after the XRNTX ended. During the treatment, cigarette smoking behaviors followed patterns of opioid use, while cocaine consumption was increased with reductions in opioid use. The present data support the hypothesis that medial prefrontal cortex functions are involved in adherence to opioid antagonist therapy. A potential role of concurrent non-opioid addictive substances consumption during the XRNTX pharmacotherapy warrants further investigation. Our findings set the stage for further bio-behavioral investigations of the mechanisms of relapse prevention in opioid dependence. PMID:25781230
Alcohol dependence: international policy implications for prison populations.

In light of the emphasis on drug abuse, this study explored the relative prevalence of substance use disorders among United Kingdom (UK) prison inmates in the context of findings from a general inmate population in the United States (US). The lead author of the report conducted a structured diagnostic interview with 155 new admissions to one of two prisons in the UK using the CAAPE (Comprehensive Addiction And Psychological Evaluation), a structured diagnostic interview, to ensure consistent assessments. The US sample consisted of 6,881 male inmates in a state prison system evaluated with an automated version of the SUDDS-IV (Substance Use Disorder Diagnostic Schedule-IV) interview. Alcohol dependence emerged as the most prevalent substance use disorder in both UK prisons and in the US sample. Relative frequencies of abuse and dependence for alcohol and other drugs revealed that dependence on a given substance was more prevalent than abuse ad defined by the current diagnostic criteria. Despite the emphasis on drugs in correctional populations, alcohol dependence appears to be the most prominent substance use disorder among the incarcerated in both the US and UK and must be considered in developing treatment programs and policy priorities.

Sex differences in neurobiological mechanisms of substance dependence are well documented but studies of sex differences in associated neurocognitive deficits have produced inconsistent results. Posttraumatic stress disorder (PTSD) is comorbid with substance dependence and frequently affects neurocognition. Thus, we investigated the effects of sex and PTSD symptoms on sustained attention and inhibition abilities among 126 female and 297 male substance-dependent individuals (SDIs) using the Immediate Memory Test (IMT). Females with significant PTSD (PTSD+) symptoms demonstrated significantly impaired IMT performance relative to other participants. These results represent progress in efforts to delineate sex-specific risk factors for neurocognitive deficits among SDIs.

Attention-deficit/hyperactivity disorder (ADHD), an early manifestation of externalizing behavior, may identify children at high risk for later substance abuse. However, the ADHD-substance abuse relationship often disappears when co-occurring conduct disorder (CD) is considered. To determine whether there is a prospective relationship between ADHD and the initiation of substance use and disorders, and whether this relationship depends on the ADHD subtype (hyperactive/impulsive or inattentive), CD, or sex. Dimensional and categorical measures of ADHD and CD were examined via logistic regression analyses in relation to subsequent initiation of tobacco, alcohol, and illicit drug use by 14 years of age and onset of substance use disorders by 18 years of age in a population-based sample of 11-year-old twins (760 female and 752 male twins) from the Minnesota Twin Family Study. Structured interviews were administered to adolescents and their mothers regarding substance use and to generate diagnoses. For boys and girls, hyperactivity/impulsivity predicted initiation of all types of substance use, nicotine dependence, and cannabis abuse/dependence (for all, P < .05), even when controlling for CD at 2 time points. By contrast, relationships between inattention and substance outcomes disappeared when hyperactivity/impulsivity and CD were controlled for, with the possible exception of nicotine dependence. A categorical diagnosis of ADHD significantly predicted tobacco and illicit drug use only (adjusted odds ratios, 2.01 and 2.82, respectively). A diagnosis of CD between 11 and 14 years of age was a powerful predictor of substance disorders by 18 years of age (all odds ratios, > 4.27). Hyperactivity/impulsivity predicts later substance problems, even after growth in later-emerging CD is considered, whereas inattention alone poses less risk. Even a single symptom of ADHD or CD is associated with increased risk. Failure in previous research to consistently observe relationships between ADHD and substance use and abuse outcomes could be due to reliance on less-sensitive categorical diagnoses.

This study examined whether duration of unemployment from ages 21 to 33 was associated with symptoms of alcohol use disorder, nicotine dependence disorder, and cannabis use disorder at age 39, after accounting for childhood and early adult involvement in substance use and other indicators of psychopathology. Analyses also investigated whether dimensions of perceived neighborhood characteristics during childhood and adolescence contributed to the link between unemployment and substance use disorder symptoms during adulthood. Potential gender differences were examined. Using life-course calendar data from a prospective longitudinal study (N=677), participants' unemployment history was measured from ages 21 to 33. General childhood and substance use-specific neighborhood characteristics were assessed at ages 10-18. Findings from negative binomial regression models showed that duration of unemployment was associated with higher levels of alcohol use disorder and nicotine dependence symptoms, after adjusting for earlier involvement in substance use. Substance use-specific neighborhood factors during childhood were associated with symptoms of nicotine dependence and cannabis use disorder. Findings also suggest that the detrimental impact of unemployment on nicotine dependence symptoms was possibly stronger for women. Findings suggest that unemployment may be an important risk factor for alcohol use disorder and nicotine dependence symptoms, indicating that public health efforts providing strategies to cope with unemployment, particularly for women who experience chronic unemployment, may be promising. Additionally, substance use-specific neighborhood characteristics during childhood should be considered as part of a prevention strategy to ameliorate adult nicotine and cannabis use problems.

Although bipolar disorder and substance use disorder frequently co-occur, there is little information on the effectiveness of behavioral treatment for this population. Integrated group therapy, which addresses the two disorders simultaneously, was compared with group drug counseling, which focuses on substance use. The authors hypothesized that patients receiving integrated group therapy would have fewer days of substance use and fewer weeks ill with bipolar disorder. A randomized controlled trial compared 20 weeks of integrated group therapy or group drug counseling with 3 months of posttreatment follow-up. Sixty-two patients with bipolar disorder and current substance dependence, treated with mood stabilizers for >or=2 weeks, were randomly assigned to integrated group therapy (N=31) or group drug counseling (N=31). The primary outcome measure was the number of days of substance use. The primary mood outcome was the number of weeks ill with a mood episode. Intention-to-treat analysis revealed significantly fewer days of substance use for integrated group therapy patients during treatment and follow-up. Groups were similar in the number of weeks ill with bipolar disorder during treatment and follow-up, although integrated group therapy patients had more depressive and manic symptoms. Integrated group therapy, a new treatment developed specifically for patients with bipolar disorder and substance dependence, appears to be a promising approach to reduce substance use in this population.

The present investigations applied a theoretical perspective regarding the impact of executive functioning (EF) on sexual risk among substance users, by using a methodological approach designed to examine whether EF subtypes differentially predict behavior patterns. Participants included 104 substance-using HIV-negative gay and bisexual men. Participants completed five neuropsychological assessment tasks selected to tap discrete EF components, and these data were linked to data on substance dependence and behavioral reports of substance use and sexual risk in the past 30 days. Cluster analysis identified three EF subtypes: a) High-performing (good performance across all measures); b) Low Performing (poor performance across all measures); and c) Poor IGT Performance (impairment on the Iowa Gambling Task (IGT) and its variant, but good performance on all other tasks). The three subtypes did not differ in amount of substance use, but the Low-Performing subtype was associated with greater rates of substance dependence. The Low-Performing subtype reported the highest rates of sexual behavior and risk, while the Poor IGT-Performance subtype reported the lowest rates of sexual risk-taking. Global associations between substance use and sexual risk were strongest among the Low-Performing subtype, but event-level associations appeared strongest among individuals in the High-Performing subtype. These data suggest complex associations between EF and sexual risk among substance users, and suggest that the relationship between substance use and sexual risk may vary by EF subtypes.

Participants completed 5 neuropsychological assessment tasks selected to tap discrete EF components, and these data were linked to data on substance dependence and behavioral reports of substance use and sexual risk in the past 30 days. Cluster analysis identified 3 EF subtypes: (a) high performing (good performance across all measures); (b) low performing (poor performance across all measures); and (c) poor IGT performance (impairment on the Iowa Gambling Task [IGT] and its variant, but good performance on all other tasks). The 3 subtypes did not differ in amount of substance use, but the low-performing subtype was associated with greater rates of substance dependence. The low-performing subtype reported the highest rates of sexual behavior and risk, while the poor-IGT-performance subtype reported the lowest rates of sexual risk taking. Global associations between substance use and sexual risk were strongest among the low-performing subtype, but event-level associations appeared strongest among individuals in the high-performing subtype. These data suggest complex associations between EF and sexual risk among substance users, and suggest that the relationship between substance use and sexual risk may vary by EF subtypes. 2013 APA, all rights reserved

Depressive symptoms often coexist with substance use disorders (SUDs). The DSM-IV has identified two distinct categories for depression coexisting with SUDs-independent depression and substance-induced depression. While this distinction has important therapeutic and prognostic implications, it remains difficult to make in clinical practice; the differentiation is often guided by chronological and symptom severity criteria that patients may be unable to precisely provide. Furthermore, it is unclear whether the various substances commonly abused-cannabis, cocaine, and opioids-are equally associated with the two types of depression. Predictors, associations, and other markers may be helpful in guiding the diagnostic process. We, therefore, examined the differences between cannabis-, cocaine-, and opioid-dependent individuals contending with independent depression and those contending with substance-induced depression in regard to several variables, hypothesizing that independent depression is more commonly found in females, and that it is associated with higher symptom severity and psychiatric comorbidity. Cocaine-, cannabis-, and/or opioid-dependent, treatment-seeking individuals underwent a structured clinical interview for DSM-IV-TR disorders after providing consent at our clinical research site; those with co-existing primary depression or substance-induced depression diagnoses were provided with further questionnaires and were entered into this analysis (n= 242). Pair-wise comparisons were conducted between the groups classified as independent versus substance-induced depression with 2-by-2 tables and chi-square tests for dichotomous independent variables, and t-tests for continuous variables. Binomial logistic regression was performed in order to ascertain which of the variables were significant predictors. Women were more likely than men to have independent depression (p< .005). Cannabis dependence was highly associated with independent depression (p< .001), while cocaine dependence was highly associated with substance-induced depression (p< .05). Independent depression was associated with higher Hamilton depression scale scores (16 vs. 10, p< .005), and was more highly associated with the comorbid diagnosis of posttraumatic stress disorder (p< .05). Cannabis dependence (p< .001) and female gender (p< .05) were highly significant predictors of major depression specifically. Gender, cannabis dependence, psychiatric severity, and psychiatric comorbidity have variable, statistically significant associations with independent and substance-induced depression, and may be helpful in guiding the diagnostic process. © American Academy of Addiction Psychiatry.
The role of emotional dysregulation in concurrent eating disorders and substance use disorders.
Spence, Sarah; Courbasson, Christine
2012-12-01
This study explored the role of emotional dysregulation in 178 participants with concurrent EDs and SUDs. We ran two path analyses: Model 1 predicted negative mood regulation from alexithymia, and Model 2 predicted emotional eating from negative mood regulation. For Model 1, difficulty identifying and describing feelings was related to poor coping expectancies, while externally-oriented thinking was related to greater coping expectancies. For Model 2, poor coping expectancies in general were related to emotional eating, while greater coping expectancies in relation to behavior (i.e., the belief that some behavior or action can alleviate one's negative affect) also resulted in increased emotional eating. This finding suggests that there may be differences in the purpose of emotional eating; some people may believe that emotional eating can be used as an effective coping strategy to deal with negative affect.

Background Recent animal and human studies reveal distinct cognitive and neurobiological differences between opiate and stimulant addictions; however, our understanding of the common and specific effects of these two classes of drugs remains limited due to the high rates of polysubstance-dependence among drug users. Methods The goal of the current study was to identify multivariate substance-specific markers classifying heroin dependence (HD) and amphetamine dependence (AD), by using machine-learning approaches. Participants included 39 amphetamine mono-dependent, 44 heroin mono-dependent, 58 polysubstance dependent, and 81 non-substance dependent individuals. The majority of substance dependent participants were in protracted abstinence. We used demographic, personality (trait impulsivity, trait psychopathy, aggression, sensation seeking), psychiatric (attention deficit hyperactivity disorder, conduct disorder, antisocial personality disorder, psychopathy, anxiety, depression), and neurocognitive impulsivity measures (Delay Discounting, Go/No-Go, Stop Signal, Immediate Memory, Balloon Analogue Risk, Cambridge Gambling, and Iowa Gambling tasks) as predictors in a machine-learning algorithm. Results The machine-learning approach revealed substance-specific multivariate profiles that classified HD and AD in new samples with high degree of accuracy. Out of 54 predictors, psychopathy was the only classifier common to both types of addiction. Important dissociations emerged between factors classifying HD and AD, which often showed opposite patterns among individuals with HD and AD. Conclusions These results suggest that different mechanisms may underlie HD and AD, challenging the unitary account of drug addiction. This line of work may shed light on the development of standardized and cost-efficient clinical diagnostic tests and facilitate the development of individualized prevention and intervention programs for HD and AD.

Although caffeine is the most commonly used psychoactive substance and often produces symptoms of toxicity and dependence, little is known, especially in community samples, about the association between caffeine use, toxicity and dependence and risk for common psychiatric and substance use disorders. Assessments of lifetime maximal caffeine use and symptoms of caffeine toxicity and dependence were available on over 3600 adult twins ascertained from the population-based Virginia Twin Registry. Lifetime histories of major depression (MD), generalized anxiety disorder (GAD) and panic disorder, alcohol dependence, adult antisocial behavior and cannabis and cocaine abuse/dependence were obtained at personal interview. Logistic regression analyses in the entire sample and within monozygotic (MZ) twin pairs were conducted in SAS. In the entire sample, measures of maximal caffeine use, heavy caffeine use, and caffeine-related toxicity and dependence were significantly and positively associated with all seven psychiatric and substance use disorders. However, within MZ twin pairs, controlling for genetic and family environmental factors, these associations, while positive, were all non-significant. These results were similar when excluding twins who denied regular caffeine use. Maximal lifetime caffeine intake and caffeine-associated toxicity and dependence are moderately associated with risk for a wide range of psychiatric and substance use disorders. Analyses of these relationships within MZ twin pairs suggest that most of the observed associations are not causal. Rather, familial factors, which are probably in part genetic, predispose to both caffeine intake, toxicity and dependence and the risk for a broad array of internalizing and externalizing disorders.

Background Dialectical Behavior Therapy (DBT) identifies emotion dysregulation as central to the dangerous impulsivity of borderline personality disorder (BPD) including substance use disorders, and DBT targets improved emotion regulation as a primary mechanism of change. However, improved emotion regulation with DBT and associations between such improvement and behavioral outcomes such as substance use has not been previously reported. Objective Thus, the goal of this study was to assess for improvement in emotion regulation and to examine the relationship between improvements in the emotion regulation and substance use problems following DBT treatment. Method Emotion regulation as assessed by the Difficulties in Emotion Regulation Scale, depressed mood as assessed by the Beck Depression Inventory, and their associations with substance use frequency were investigated in 27 women with substance dependence and BPD receiving 20 weeks of DBT in an academic community outpatient substance abuse treatment program. Results indicated improved emotion regulation, improved mood, and decreased substance use frequency. Further, emotion regulation improvement, but not improved mood, explained the variance of decreased substance use frequency. Conclusions This is the first study to demonstrate improved emotion regulation in BPD patients treated with DBT and to show that improved emotion regulation can account for increased behavioral control in BPD patients. Significance and Future Research Emotion regulation assessment is recommended for future studies to further clarify the etiology and maintenance of disorders associated with emotional dyregulation such as BPD and substance dependence, and to further explore emotion regulation as a potential mechanism of change for clinical interventions.

Among substance-dependent individuals, comorbid major depressive disorder (MDD) is associated with greater severity and poorer treatment outcomes, but little research has examined mediators of posttreatment substance use outcomes within this population. Using latent growth curve models, the authors tested relationships between individual rates of change in 12-step involvement and substance use, utilizing posttreatment follow-up data from a trial of group Twelve-Step Facilitation (TSF) and integrated cognitive-behavioral therapy (ICBT) for veterans with substance dependence and MDD. Although TSF patients were higher on 12-step affiliation and meeting attendance at end-of-treatment as compared with ICBT, they also experienced significantly greater reductions in these variables during the year following treatment, ending at similar levels as ICBT. Veterans in TSF also had significantly greater increases in drinking frequency during follow-up, and this group difference was mediated by their greater reductions in 12-step affiliation and meeting attendance. Patients with comorbid depression appear to have difficulty sustaining high levels of 12-step involvement after the conclusion of formal 12-step interventions, which predicts poorer drinking outcomes over time. Modifications to TSF and other formal 12-step protocols or continued therapeutic contact may be necessary to sustain 12-step involvement and reduced drinking for patients with substance dependence and MDD.

The purpose of this research was to expand knowledge in the current literature regarding treatment retention in intensive outpatient substance abuse treatment programs. The sample in this study participated in a hospital-based program accredited by the Joint Commission on Accreditation for Health Organizations (JCAHO) that utilized the Minnesota model. Specifically, this inquiry investigated whether treatment retention would be predicted by gender, age, employment status, number of problems on the treatment plan, whether the referral was related to driving while intoxicated (DWI), marital status, race, and whether each of the following substance problems was listed as the client's primary DSM-IV diagnosis: alcohol dependence, cocaine dependence, polysubstance dependence, opioid dependence, sedative/hypnotic dependence, cannabis dependence, other (or unknown) dependence, alcohol abuse, cannabis abuse, amphetamine abuse, and caffeine intoxication. Findings indicated that those retained in treatment, when compared to those who dropped out, had significantly more problems on their treatment plans, were more likely to be alcoholics, were less often cocaine addicts, and were more likely to be employed. The results of this study suggest that clients with this profile have increased likelihood of being retained in intensive outpatient substance abuse treatment programs.

In psychiatric care practice, patients are often seen who have difficulty with their social lives due to protracted psychiatric symptoms despite years without drug abuse. The difficulty of dealing with such cases and the lack of preparedness of the legal system leave circumstantial care as the only option. Western.countries have recently begun using the name 'concurrent disorder' as a diagnosis for patients deemed unable to recover solely through such treatment for drug addiction, signifying the presence of both a substance use disorder (SUD) and a mental health disorder. Various assessment and intervention methods are being investigated, and many studies have been reported. Based on the hypothesis that Drug Addiction Rehabilitation Center (DARC) are partly involved in supporting those with psychotic concurrent disorders (PSCD) in Japan, we conducted a survey to clarify the actual support for PSCD patients at DARC and the challenges they face. Surveys were administered to DARC-related institutions all over Japan (44 governing organizations and 66 institutions). Complete responses from 86 full-time employees and 445 DARC users were analyzed. DARC users were divided into two groups: psychiatric concurrent disorders (PSCD group, n = 178) and those without such symptoms (SUD group, n = 267), with the PSCD group accounting for 40% of the DARC users surveyed. Compared to the SUD group, the PSCD group was significantly less satisfied with their lifestyle and interpersonal relations at the DARC and a significantly higher proportion of the PSCD group requested assistance in communicating with others. When employees were presented with a hypothetical PSCD case and asked what was needed to deal with it, some responses were, "an institution that can treat both drug addiction and other mental health disorders," "a psychiatric care institution that provides 24-hour care," and "sufficient manpower and training." In the future, a treatment system must be established based on public medical institutions with a dedicated PSCD program that can provide medical care under legal observation.
Evidence that anhedonia is a symptom of opioid dependence associated with recent use.

Anhedonia is prevalent among substance-dependent populations. The hedonic allostasis model suggests this is due to the effects of addictive substances on neural substrates of reward processing. However, previous research may have been confounded by other factors likely to influence anhedonia, including tobacco use, psychopathology, and history of trauma and other stressors. Thus it remains unclear whether elevated anhedonia in substance-dependent populations is caused by substance use itself, or is due to other correlates of substance dependence. Multivariate analysis of covariance was conducted to test whether opioid-dependent participants' anhedonia scores were elevated, relative to a non-dependent control group, after controlling for psychosocial factors likely to influence anhedonia. Correlational analyses within opioid-dependent participants were also conducted to examine whether anhedonia was associated with recent illicit opioid use or duration of abstinence. There was a modest, but significant, elevation in anhedonia in opioid-dependent participants, relative to controls (Partial η 2 =0.034, p=0.041) after controlling for psychosocial variables that were associated with anhedonia. Depressive symptoms and history of post-traumatic stress disorder also remained significantly associated with anhedonia in the adjusted model. Among participants on opioid pharmacotherapy, there were significant associations between frequency of recent illicit opioid use and scores on anhedonia measures (all r s >0.25, p<0.013), but among abstinent opioid-dependent participants, relationships between duration of abstinence and anhedonia were not significant (all r s <0.24, p>0.22). These findings support the hypothesis that use of opioids can cause anhedonia, although other psychosocial factors may also contribute to the high prevalence of anhedonia among opioid-dependent populations.

We describe relationships between substance use, conduct disorder (CD), depression, and history of self-injury or suicide attempts, in referred, delinquent, substance involved, adolescent males. Sixty youths (mean age 16.3 years) completed standardized assessments for substance use and other psychiatric disorders, aggressiveness, and social class. All boys met modified criteria for CD. Most had high aggression ratings. Twenty percent had depressive diagnoses. By age 13, 78% had begun regular substance use. Marijuana was the first substance for 42%. The boys had substance dependence on a mean of 3.2 different drugs (usually including alcohol and marijuana), with abuse of an average of one additional drug. CD symptoms began 3.6 years (mean) before regular use. CD symptom count correlated with number of dependence diagnoses, and both of those (but not depression) related significantly to suicide attempt and self-injury histories. Improved understanding of substance involvement in youths with CD may generate more rational prevention and treatment.

Substance P and bombesin induce contraction of isolated IAS smooth muscle cells by different intracellular mechanisms. The cells contracted in a dose dependent manner to both peptides. The kinetics of contraction were different. Substance P induced contraction peaked at 30 seconds and declined in a time dependent manner while bombesin induced contraction peaked at 30 seconds and was maintained for up to 8 minutes. The absence of extracellular calcium in the medium (0 calcium and 2 mM EGTA) had no affect on substance P induced contraction while it blocked bombesin induced contraction. Substance P induced contraction was blocked by the calmodulin antagonist W7 (10(-9)M) and was not affected by the PKC antagonist H7 (10(-6)M). Bombesin induced contraction was blocked by the PKC antagonist H7 and was not affected by the calmodulin antagonist W7. Our data indicate that substance P induces a transient contraction utilizing intracellular calcium and a calmodulin dependent pathway, while bombesin induces a sustained contraction utilizing calcium from extracellular sources and a calmodulin independent pathway.

Introduction The present study aims to examine the role of emotion dysregulation and childhood maltreatment in self mutilation (SM) of substance dependent patients. Specifically, the present study examined whether emotion dysregulation and its dimensions, and childhood maltreatment and its dimensions were associated with SM. The relationship between emotion dysregulation and childhood maltreatment was also investigated. Methods The sample of study consisted of 55 alcohol dependent and 24 opiate dependent patients (n=79). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV-TR (SCID-I), Turkish version. Childhood Trauma Questionnaire (CTQ) and Difficulties in Emotion Regulation Scale (DERS) were used. Results Findings indicated that substance dependents with SM and without SM were differentiated in terms of overall emotion dysregulation. Results also suggest the relevance of three specific dimensions of emotion dysregulation to SM: Difficulties engaging in goal-directed behaviors when experiencing negative emotions, difficulties controlling impulsive behaviors when experiencing negative emotions, and limited access to effective emotion regulation strategies. These dimensions were predicted from childhood emotional maltreatment and neglect. It is also revealed that substance dependents with SM had higher points than those without SM on emotional childhood maltreatment and neglect, physical childhood maltreatment. Conclusion Results were supported by the literature suggested that self-mutilation functions as a emotional regulation strategy. Findings also suggested that self- mutilation is related to early relationships take place in family environment in which individuals grow up. PMID:28360668

Substance dependence is complex and multifactorial, with many distinct pathways involved in both the development and subsequent maintenance of addictive behaviors. Various cognitive mechanisms have been implicated, including impulsivity, compulsivity, and impaired decision-making. These mechanisms are modulated by emotional processes, resulting in increased likelihood of initial drug use, sustained substance dependence, and increased relapse during periods of abstinence. Emotional traits, such as sensation-seeking, are risk factors for substance use, and chronic drug use can result in further emotional dysregulation via effects on reward, motivation, and stress systems. We will explore theories of hyper and hypo sensitivity of the brain reward systems that may underpin motivational abnormalities and anhedonia. Disturbances in these systems contribute to the biasing of emotional processing toward cues related to drug use at the expense of natural rewards, which serves to maintain addictive behavior, via enhanced drug craving. We will additionally focus on the sensitization of the brain stress systems that result in negative affect states that continue into protracted abstinence that is may lead to compulsive drug-taking. We will explore how these emotional dysregulations impact upon decision-making controlled by goal-directed and habitual action selections systems, and, in combination with a failure of prefrontal inhibitory control, mediate maladaptive decision-making observed in substance dependent individuals such that they continue drug use in spite of negative consequences. An understanding of the emotional impacts on cognition in substance dependent individuals may guide the development of more effective therapeutic interventions. PMID:23162443
[Quetiapine in substance use disorders, abuse and dependence possibility: a review].
Erdoğan, Serap
2010-01-01
Quetiapine is an atypical antipsychotic approved by the FDA (Food and Drug Administration) for use in the treatment of schizophrenia, acute mania, and bipolar depression. Pharmacologically, it has antagonistic effects on serotonin 5-HT1A and 5-HT2A, dopamine D1 and D2, histamine H1, and adrenergic alpha1 and alpha2 receptors. In addition to reports of its use in schizophrenia and bipolar disorder, many studies have examined the use of quetiapine in the treatment of anxiety disorders and substance use disorders. In the treatment of patients with psychotic or bipolar disorder with a comorbid substance abuse disorder even though quetiapine was prescribed primarily for the treatment of the underlying psychotic symptoms, patients taking this medication reported a significant reduction in substance use. Yet, there are also case reports of quetiapine abuse and dependence; in particular among prisoners and patients diagnosed with substance abuse. Though quetiapine should be used peroral, it is also used intranasally and intravenously in these patient groups. Moreover, in some cases quetiapine is combined with other substances, such as cocaine or marijuana, to increase sedation. This abuse of quetiapine is thought to occur due to the anxiolytic and sedative effects of the drug. There are no controlled studies on quetiapine dependence in the literature and it remains unknown whether or not quetiapine causes dependence. This review aimed to present all published case reports on quetiapine abuse and to discuss the possible mechanisms that underlie its abuse and dependence.
[Doping: health risks and relation to addictive behaviors].
Siri, Françoise; Roques, Bernard P
2003-11-01
The paper presents the health hazards of the major doping substances and raises some questions about the relationship between doping and addictive behavior. Current definitions of doping and addictive behavior are examined. The paper's goal is: 1- to assess the risks of neurotoxicity and overall toxicity of doping substances: stimulants, narcotics (seldom used as doping substances), and hormones, and assess their addictive potential; 2- to present available data on drug-dependent patients with a record of early prolonged and intensive physical activity or athletic practice. Some doping substances present high risks for health at large doses, but usually low addictive potential and neurotoxicity. Dependency on doping substances and drift towards dependency to addictive drugs, if any, are therefore determined by genetic and environmental factors. A significant susceptibility to drug dependence has been observed in some cases of very intensive and competitive practice. Over-representation of intensive and competitive athletic antecedents among some drug-dependent patients could be accounted for in either of two ways. On the first account, the causal factor is a sensation-seeking character trait, with a likely genetic component, which predisposes the individual to the use of drugs or doping substances, as the opportunities arise. On the second account, the sudden interruption of intensive practice, and of the associated organic stress and hypersensitization of the hedonic pathway, creates a weaning syndrome and leads to the search for relief through drugs. Further exploration of this hypothesis is called for.

A number of demographic factors, psychiatric disorders, and childhood risk factors have been associated with cocaine dependence (CD) and opioid dependence (OD), but little is known about their relevance to the rate at which dependence develops. Identification of the subpopulations at elevated risk for rapid development of dependence and the risk factors that accelerate the course of dependence is an important public health goal. Data were derived from cocaine dependent (n=6333) and opioid dependent (n=3513) participants in a multi-site study of substance dependence. Mean age was approximately 40 and 40% of participants were women; 51.9% of cocaine dependent participants and 29.5% of opioid dependent participants self-identified as Black/African-American. The time from first use to dependence was calculated for each substance and a range of demographic, psychiatric, and childhood risk factors were entered into ordinal logistic regression models to predict the (categorical) transition time to CD and OD. In both the cocaine and opioid models, conduct disorder and childhood physical abuse predicted rapid development of dependence and alcohol and nicotine dependence diagnoses were associated with slower progression to CD or OD. Blacks/African Americans were at greater risk than European Americans to progress rapidly to OD. Only a subset of factors known to be associated with CD and OD predicted the rate at which dependence developed. Nearly all were common to cocaine and opioids, suggesting that sources of influence on the timing of transitions to dependence are shared across the two substances. © 2013.

The maximum cumulative ratio (MCR) method allows the categorisation of mixtures according to whether the mixture is of concern for toxicity and if so whether this is driven by one substance or multiple substances. The aim of the present study was to explore, by application of the MCR approach, whether health risks due to indoor air pollution are dominated by one substance or are due to concurrent exposure to various substances. Analysis was undertaken on monitoring data of four European indoor studies (giving five datasets), involving 1800 records of indoor air or personal exposure. Application of the MCR methodology requires knowledge of the concentrations of chemicals in a mixture together with health-based reference values for those chemicals. For this evaluation, single substance health-based reference values (RVs) were selected through a structured review process. The MCR analysis found high variability in the proportion of samples of concern for mixture toxicity. The fraction of samples in these groups of concern varied from 2% (Flemish schools) to 77% (EXPOLIS, Basel, indoor), the variation being due not only to the variation in indoor air contaminant levels across the studies but also to other factors such as differences in number and type of substances monitored, analytical performance, and choice of RVs. However, in 4 out of the 5 datasets, a considerable proportion of cases were found where a chemical-by-chemical approach failed to identify the need for the investigation of combined risk assessment. Although the MCR methodology applied in the current study provides no consideration of commonality of endpoints, it provides a tool for discrimination between those mixtures requiring further combined risk assessment and those for which a single-substance assessment is sufficient.

The aim of the current investigation was to examine uni-morbid and co-occurring tobacco and marijuana use in relation to the negative emotional symptoms of anxiety and depression. Participants were 250 adult individuals (132 female; mage = 22.43, SD = 9.00), falling into one of four non-overlapping substance use categories: tobacco use only (n = 39), marijuana use only (n = 62), co-occurring tobacco and marijuana use (n = 82), and neither tobacco nor marijuana use (n = 67). Results revealed three key findings. First, tobacco-only using individuals reported significantly greater negative affectivity than any of the other groups. Second, tobacco-only users reported greater anxious arousal symptoms than either the marijuana or non-substance-using groups, but not the combined group. Third, tobacco-only users reported greater levels of depressive symptoms than either marijuana users or non-substance-users. These findings provide novel information about tobacco and marijuana use, and how these variables relate to the experience of general and specific types of negative emotional symptoms. PMID:20390700

Research in the United States tends to indicate that immigrants from most sociogeographic regions have considerably lower substance use disorder (SUD) rates than native born individuals. We aimed to analyze the differences between immigrants and native born population regarding substance abuse and dependence. This objective was approached using data from the ARACAT cross-sectional multicenter study in primary care settings of two different Spanish regions: Aragon and Catalonia. Three thousand six patients (1,503 immigrants randomly selected and 1,503 native born paired by age and gender) were interviewed using the Mini-International Neuropsychiatric Interview. Reported substance abuse and dependence were more prevalent in the native born population than in immigrants (alcohol abuse 5.1% vs. 2.6% p < .0001, alcohol dependence 3.3% vs. 2.6% n.s., other abuse 3.4% vs. .4% p < .0001, other dependence .5% vs. 4.0% p < .0001). Large differences were detected between different ethnic groups. Sociodemographic characteristics such as female gender, older age, higher level of education or stable housing (among others), were found to be protective against different SUDs. Immigrants have lower levels of alcohol and substance abuse, however, those that do consume show higher levels of both comorbid mental disorders and problematic alcohol/substance use. It would appear to be the case that issues specific to immigrant cultures, such as extreme stigmatization of substance and alcohol use, may serve to promote social marginalization and inhibit treatment access. © American Academy of Addiction Psychiatry.

Addiction is a phenomenon that causes structural changes in different systems of society. Studies show for planning of addiction prevention and treatment, it is necessary to create an information management system. Substance dependence information systems refer to systems which collect, analyse and report data related to substance dependence information. The aim of this study was to identify advantages and barriers to implement Substance Dependence Treatment Information System (SDTIS). This study was a narrative review. Our review divided into three phases: literature collection, assessing, and selection. We employed the following keywords and their combinations in different areas of articles. In this study, 22 of collected articles and reports were selected based on their relevancy. We found many advantages for a substance dependence treatment information system such as recording sufficient, complete and accurate information and easy and timely access to them and monitoring and enhancing the quality of care received by patients. But we may face some concerns for implementing this information system like taking time and funds from client services, being expensive or even problems regarding the quality of data contained in these information systems. There are some important problems in the way of implementing. In order to overcome these issues, we need to raise community awareness.

Intensive case management (ICM) is effective for facilitating entry into and retention in outpatient substance use disorder treatment (OSUDT) for low-income substance-dependent women; however, no studies have specifically examined the moderating impact of depressive symptoms on ICM. The purpose of this study was to investigate whether depressive symptoms moderated ICM's effect on OSUDT engagement, attendance, and outcomes for substance-dependent women on Temporary Assistance for Needy Families (TANF). It was hypothesized that highly depressed women would demonstrate worse outcomes on all indicators. Logistic regression and generalized estimating equations were used to determine depression's moderating impact on ICM in a secondary analysis of data from a randomized controlled trial comparing the effectiveness of ICM to usual care provided by local public assistance offices in Essex County, NJ. Substance-dependent women (N = 294) were recruited while being screened for TANF eligibility and were followed for 24 months. Findings revealed that high levels of depressive symptoms moderated the effectiveness of ICM in unexpected directions for two outcome variables. Subjects with high levels of depressive symptoms in ICM were (a) significantly more likely to engage in at least one treatment program than those in usual care and (b) associated with the fewest mean drinks per drinking day across the 24-month follow-up period. Independent effects for high levels of depressive symptoms and ICM were also found to positively influence engagement, attendance, and percentage days abstinent. ICM is effective for substance-dependent women with a broad spectrum of depressive symptoms in enhancing OSUDT utilization and outcomes.

The aim of this study was to evaluate the prevalence of suicide in Turkish male substance dependents, and to investigate the relationship of suicide attempt history with childhood abuse and neglect, alexithymia, and temperament and character dimensions of personality. Participants were 154 consecutively admitted male substance dependents. Patients were investigated with the Childhood Abuse and Neglect Questionnaire, Toronto Alexithymia Scale (TAS-20) and Temperament and Character Inventory (TCI). Among substance-dependent patients, 28.6% was considered a group with suicide attempt history (SAH). Current age was lower and rate of being single was higher in the group with SAH. There were no significant differences between groups in terms of employment, educational status and duration of education. Rates of physical, emotional abuse and neglect, self-mutilation and being alexithymic were higher and ages at first substance use and regular substance use were lower in the group with SAH. Mean scores of "difficulty in identifying feelings" (DIF) and "difficulty in describing feelings" (DDF) subscale EOT of the TAS-20 were higher in the SAH group. Among temperament and character dimensions of the TCI, only "Self-directedness" and "Cooperativeness" were lower in SAH and there were no significant differences between groups in terms of other subscales. Age and Self-directedness score of TCI were determinants for suicide attempt. In particular, young drug users with low Self-directedness scores could be the target population in order to prevent suicidal behavior. This study also suggests that in substance-dependent patients, in the background of all suicidal behavior, childhood abuse and neglect must be evaluated.

Genetic influences contribute significantly to co-morbidity between conduct disorder and substance use disorders. Estimating the extent of overlap can assist in the development of phenotypes for genomic analyses. Multivariate quantitative genetic analyses were conducted using data from 9577 individuals, including 3982 complete twin pairs and 1613 individuals whose co-twin was not interviewed (aged 24-37 years) from two Australian twin samples. Analyses examined the genetic correlation between alcohol dependence, nicotine dependence and cannabis abuse/dependence and the extent to which the correlations were attributable to genetic influences shared with conduct disorder. Additive genetic (a(2) = 0.48-0.65) and non-shared environmental factors explained variance in substance use disorders. Familial effects on conduct disorder were due to additive genetic (a(2) = 0.39) and shared environmental (c(2) = 0.15) factors. All substance use disorders were influenced by shared genetic factors (rg = 0.38-0.56), with all genetic overlap between substances attributable to genetic influences shared with conduct disorder. Genes influencing individual substance use disorders were also significant, explaining 40-73% of the genetic variance per substance. Among substance users in this sample, the well-documented clinical co-morbidity between conduct disorder and substance use disorders is primarily attributable to shared genetic liability. Interventions targeted at generally reducing deviant behaviors may address the risk posed by this shared genetic liability. However, there is also evidence for genetic and environmental influences specific to each substance. The identification of these substance-specific risk factors (as well as potential protective factors) is critical to the future development of targeted treatment protocols.

Objectives: A secondary analysis assessed health-related quality of life characteristics (i.e. anxiety, depression, fatigue, and types of pain) among patients entering substance-use treatment, and identified characteristics specific to treatment modalities relative to a representative comparison group. Methods: As part of a larger alcohol bank assessment, substance-use patients (n=406) beginning methadone treatment (n=170) or other outpatient treatment (n=236) and a comparison group representative of the general population (n=1000) completed a survey measuring anxiety, depression, fatigue, pain interference, and pain in the last 7 days. Previous studies lacked comparable and concurrent assessments across these three groups. Results: Patients entering substance-use treatment had relatively high levels of emotional distress and poorer health-related quality of life relative to the general population. Among treatment modalities, patients beginning methadone treatment reported the highest levels of pain interference and pain behavior and the poorest physical functioning. Prior to the potentially modifying effects of methadone maintenance, patients beginning agonist therapy reported the greatest levels of compromised quality of life. Conclusion: These data present the magnitude of differences in health-related quality of life characteristics between treatment and comparison groups using the same assessment rubric and may help inform the design and timing of treatment modalities, thereby enhancing treatment efficacy for patients.

Background Attention-deficit /hyperactivity disorder (ADHD) is associated with substance use and substance use disorders (SUD). However, relatively little is known about the relationship between DSM-IV ADHD subtypes and substance use or DSM-IV abuse/dependence in epidemiological samples. Methods Data were obtained from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC, N=33,588). Respondents reported on ADHD symptoms (DSM-IV) for the period of time when they were 17 years or younger. Lifetime use and DSM-IV abuse/dependence of alcohol, nicotine, cannabis, cocaine, sedatives, stimulants and heroin/opiates were compared across those with ADHD symptoms but no diagnosis (ADHDsx; N=17,009), the Combined (ADHD-C; N=361), Predominantly Inattentive (ADHD-I; N=325), and the Predominantly Hyperactive-Impulsive (ADHD-HI; N=279) ADHD subtypes. Taking a more dimensional approach, inattentive and hyperactive-impulsive symptom counts and their associations with substance use and misuse were also examined. Results After adjustments for conduct disorder, major depressive disorder, any anxiety disorder and other socio-demographic covariates, substance use and SUD were associated with ADHDsx, ADHD-C, ADHD-I and ADHD-HI. Overall, substance use and SUD were more weakly associated with the ADHDsx group compared to the three ADHD diagnostic groups. Statistically significant differences were not evident across the three diagnostic groups. Hyperactive-impulsive symptoms were more consistently associated with substance use and SUD compared to inattentive symptoms. Conclusions ADHD subtypes are consistently associated with substance use and SUD. The relatively stronger association of hyperactive/impulsive symptoms with substance use and abuse/dependence is consistent with the extant literature noting impulsivity as a precursor of substance use and SUD.

A spatially collocated sound thrusts a flash into awareness

To interact effectively with the environment the brain integrates signals from multiple senses. It is currently unclear to what extent spatial information can be integrated across different senses in the absence of awareness. Combining dynamic continuous flash suppression (CFS) and spatial audiovisual stimulation, the current study investigated whether a sound facilitates a concurrent visual flash to elude flash suppression and enter perceptual awareness depending on audiovisual spatial congruency. Our results demonstrate that a concurrent sound boosts unaware visual signals into perceptual awareness. Critically, this process depended on the spatial congruency of the auditory and visual signals pointing towards low level mechanisms of audiovisual integration. Moreover, the concurrent sound biased the reported location of the flash as a function of flash visibility. The spatial bias of sounds on reported flash location was strongest for flashes that were judged invisible. Our results suggest that multisensory integration is a critical mechanism that enables signals to enter conscious perception. PMID:25774126

Recent animal and human studies reveal distinct cognitive and neurobiological differences between opiate and stimulant addictions; however, our understanding of the common and specific effects of these two classes of drugs remains limited due to the high rates of polysubstance-dependence among drug users. The goal of the current study was to identify multivariate substance-specific markers classifying heroin dependence (HD) and amphetamine dependence (AD), by using machine-learning approaches. Participants included 39 amphetamine mono-dependent, 44 heroin mono-dependent, 58 polysubstance dependent, and 81 non-substance dependent individuals. The majority of substance dependent participants were in protracted abstinence. We used demographic, personality (trait impulsivity, trait psychopathy, aggression, sensation seeking), psychiatric (attention deficit hyperactivity disorder, conduct disorder, antisocial personality disorder, psychopathy, anxiety, depression), and neurocognitive impulsivity measures (Delay Discounting, Go/No-Go, Stop Signal, Immediate Memory, Balloon Analogue Risk, Cambridge Gambling, and Iowa Gambling tasks) as predictors in a machine-learning algorithm. The machine-learning approach revealed substance-specific multivariate profiles that classified HD and AD in new samples with high degree of accuracy. Out of 54 predictors, psychopathy was the only classifier common to both types of addiction. Important dissociations emerged between factors classifying HD and AD, which often showed opposite patterns among individuals with HD and AD. These results suggest that different mechanisms may underlie HD and AD, challenging the unitary account of drug addiction. This line of work may shed light on the development of standardized and cost-efficient clinical diagnostic tests and facilitate the development of individualized prevention and intervention programs for HD and AD.

Alcohol and marijuana are the two most abused substances in US colleges. However, research on the combined influence (cross sectional or longitudinal) of these substances on academic performance is currently scant. Data were derived from the longitudinal 2-year Brain and Alcohol Research in College Students (BARCS) study including 1142 freshman students who completed monthly marijuana use and alcohol consumption surveys. Subjects were classified into data-driven groups based on their alcohol and marijuana consumption. A linear mixed-model (LMM) was employed using this grouping factor to predict grade point average (GPA), adjusted for a variety of socio-demographic and clinical factors. Three data-driven clusters emerged: 1) No/low users of both, 2) medium-high alcohol/no-low marijuana, and 3) medium-high users of both substances. Individual cluster derivations between consecutive semesters remained stable. No significant interaction between clusters and semester (time) was noted. Post-hoc analysis suggest that at the outset, compared to sober peers, students using moderate to high levels of alcohol and low marijuana demonstrate lower GPAs, but this difference becomes non-significant over time. In contrast, students consuming both substances at moderate-to-high levels score significantly lower at both the outset and across the 2-year investigation period. Our follow-up analysis also indicate that when students curtailed their substance use over time they had significantly higher academic GPA compared to those who remained stable in their substance use patterns over the two year period. Overall, our study validates and extends the current literature by providing important implications of concurrent alcohol and marijuana use on academic achievement in college.

The Positive and Negative Affect Schedule (PANAS) is a widely used measure of affect. A comprehensive psychometric evaluation among substance users, however, has not been published. To examine the psychometric properties of the PANAS in a sample of outpatient treatment substance users. We used pooled data from four randomized clinical trials (N = 416; 34% female, 48% African American). A confirmatory factor analysis indicated adequate support for a two-factor correlated model comprised of Positive Affect and Negative Affect with correlated item errors (Comparative Fit Index = 0.93, Root Mean Square Error of Approximation = 0.07, χ(2) = 478.93, df = 156). Cronbach's α indicated excellent internal consistency for both factors (0.90 and 0.91, respectively). The PANAS factors had good convergence and discriminability (Composite Reliability > 0.7; Maximum Shared Variance < Average Variance Extracted). A comparison from baseline to Week 1 indicated acceptable test-retest reliability (Positive Affect = 0.80, Negative Affect = 0.76). Concurrent and discriminant validity were demonstrated with correlations with the Brief Symptom Inventory and Addiction Severity Index. The PANAS scores were also significantly correlated with treatment outcomes (e.g. Positive Affect was associated with the maximum days of consecutive abstinence from primary substance of abuse, r = 0.16, p = 0.001). Our data suggest that the psychometric properties of the PANAS are retained in substance using populations. Although several studies have focused on the role of Negative Affect, our findings suggest that Positive Affect may also be an important factor in substance use treatment outcomes.

In the present study, we have investigated the effects of a novel prolyl endopeptidase (EC 3.4.21.26, PEP) inhibitor, compound S 17092, on substance P (SP) and alpha-melanocyte-stimulating hormone (alpha-MSH) metabolism in the rat brain. In vitro experiments revealed that S 17092 inhibits in a dose-dependent manner PEP activity in rat cortical extracts (IC50 = 8.3 nm). In addition, S 17092 totally abolished the degradation of SP and alpha-MSH induced by bacterial PEP. In vivo, a significant decrease in PEP activity was observed in the medulla oblongata after a single oral administration of S 17092 at doses of 10 and 30 mg/kg (-78% and -82%, respectively) and after chronic oral treatment with S 17092 at doses of 10 and 30 mg/kg per day (-75% and -88%, respectively). Concurrently, a single administration of S 17092 (30 mg/kg) caused a significant increase in SP- and alpha-MSH-like immunoreactivity (LI) in the frontal cortex (+41% and +122%, respectively) and hypothalamus (+84% and +49%, respectively). In contrast, chronic treatment with S 17092 did not significantly modify SP- and alpha-MSH-LI in the frontal cortex and hypothalamus. Collectively, the present results show that S 17092 elevates SP and alpha-MSH concentrations in the rat brain by inhibiting PEP activity. These data suggest that the effect of S 17092 on memory impairment can be accounted for, at least in part, by inhibition of catabolism of promnesic neuropeptides such as SP and alpha-MSH.

This study evaluated the clinical and sociodemographic features associated with various degrees of concurrent comorbidity in adult outpatients with nonpsychotic major depressive disorder (MDD). Outpatients enrolled in the STAR*D trial completed the Psychiatric Diagnostic Screening Questionnaire (PDSQ). An a priori 90% specificity threshold was set for PDSQ responses to ascertain the presence of 11 different concurrent DSM-IV Axis I disorders. Of 1376 outpatients, 38.2% had no concurrent comorbidities, while 25.6% suffered one, 16.1% suffered two, and 20.2% suffered three or more comorbid conditions. Altogether, 29.3% met threshold for social anxiety disorder, 20.8% for generalized anxiety disorder, 18.8% for posttraumatic stress disorder, 12.4% for bulimia, 11.9% for alcohol abuse/dependence, 13.4% for obsessive-compulsive disorder, 11.1% for panic disorder, 9.4% for agoraphobia, 7.3% for drug abuse/dependence, 3.7% for hypochondriasis, and 2.2% for somatoform disorder. Those with more concurrent Axis I conditions had earlier ages at first onset of MDD, longer histories of MDD, greater depressive symptom severity, more general medical comorbidity (even though they were younger than those with fewer comorbid conditions), poorer physical and mental function, health perceptions, and life satisfaction; and were more likely to be seen in primary care settings. Participants had to meet entry criteria for STAR*D. Ascertainment of comorbid conditions was not based on a structured interview. Concurrent Axis I conditions (most often anxiety disorders) are very common with MDD. Greater numbers of concurrent comorbid conditions were associated with increased severity, morbidity, and chronicity of their MDD.
Topiramate in the treatment of substance-related disorders: a critical review of the literature.
Shinn, Ann K; Greenfield, Shelly F
2010-05-01
To critically review the literature on topiramate in the treatment of substance-related disorders. A PubMed search of human studies published in English through January 2009 was conducted using the following search terms: topiramate and substance abuse, topiramate and substance dependence, topiramate and withdrawal, topiramate and alcohol, topiramate and nicotine, topiramate and cocaine, topiramate and opiates, and topiramate and benzodiazepines. 26 articles were identified and reviewed; these studies examined topiramate in disorders related to alcohol, nicotine, cocaine, methamphetamine, opioids, Ecstasy, and benzodiazepines. Study design, sample size, topiramate dose and duration, and study outcomes were reviewed. There is compelling evidence for the efficacy of topiramate in the treatment of alcohol dependence. Two trials show trends for topiramate's superiority over oral naltrexone in alcohol dependence, while 1 trial suggests topiramate is inferior to disulfiram. Despite suggestive animal models, evidence for topiramate in treating alcohol withdrawal in humans is slim. Studies of topiramate in nicotine dependence show mixed results. Human laboratory studies that used acute topiramate dosing show that topiramate actually enhances the pleasurable effects of both nicotine and methamphetamine. Evidence for topiramate in the treatment of cocaine dependence is promising, but limited by small sample size. The data on opioids, benzodiazepines, and Ecstasy are sparse. Topiramate is efficacious for the treatment of alcohol dependence, but side effects may limit widespread use. While topiramate's unique pharmacodynamic profile offers a promising theoretical rationale for use across multiple substance-related disorders, heterogeneity both across and within these disorders limits topiramate's broad applicability in treating substance-related disorders. Recommendations for future research include exploration of genetic variants for more targeted pharmacotherapies. ©Copyright 2010 Physicians Postgraduate Press, Inc.

Substance use disorder is characterized by impaired decision making, impulsivity, and risk taking. Pathological gambling shares many of these characteristics, and having both diagnoses may be associated with greater problems than either diagnosis alone. We investigated whether among substance-dependent individuals, comorbid pathological gambling would be associated with worse decision making, greater impulsivity, risk taking, and drug severity. Ninety-six substance-dependent individuals were recruited from a residential treatment program and divided into 1 of the 2 groups depending on whether they met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for pathological gambling (SDPG, n = 26) or not (SD, n = 70). Ninety-two controls were recruited from the community. Participants completed a decision-making task (modified Iowa Gambling Task), measures of impulsivity (Barratt Impulsivity Scale and Delay Discounting), and risk taking (Balloon Analog Risk Task). Decision making was analyzed using a computational model. We tested for group differences using analysis of covariance or Kruskal-Wallis and appropriate post-hoc tests. The groups differed in decision-making parameters (P < 0.001) and self-reported impulsivity (P < 0.001). All post-hoc comparisons were significant on these measures, and indicated stepwise changes in controls, followed by SD, followed by SDPG, with SDPG performing worse on decision making and being more impulsive. Compared with SD, SDPG had greater drug severity (P < 0.001). No group differences were observed in delay discounting or risk taking. Compared with individuals with substance dependence without pathological gambling, those with both disorders demonstrated worse decision making and significantly more drug-related symptoms. When evaluating patients with substance dependence, clinicians should consider diagnostic assessments for gambling, as the co-occurrence of both disorders may impact clinical characteristics.

There is a reasonable theoretical base for understanding the possible causes and motivations behind substance misuse and its dependency. There is a need for a reliable and valid measure that delineates the markers of substance use from its initiation and identifies different motivations for drug use transitioning, maintenance, and dependency. We addressed this gap in the United Kingdom by examining and validating the Substance Transitions in Addiction Rating Scale (STARS). For this review, 390 male prisoners were screened for conduct disorder and assessed with a clinical diagnostic interview for attention deficit/hyperactivity disorder (ADHD). They completed the four STARS subscales regarding their substance use. Exploratory structural equation modeling was performed to assess the STARS structure and to derive factors to assess validity against ADHD and conduct disorder diagnostic categories. Each of the subscales produced meaningful and reliable factors that supported the self-medication and behavioral disinhibition hypotheses of substance use motivation. The findings robustly show that ADHD is significantly associated with the need for coping as a way of managing primary and comorbid symptoms, but not conduct disorder. The findings were strongest for the combined ADHD type. STARS has a great potential to further the understanding of the motivation behind substance use and its dependency in different populations.

Previous studies have shown that when assessing child psychopathology, parents tend to report more symptoms than children for externalizing disorders such as attention deficit hyperactivity disorder (ADHD), whereas children tend to report more symptoms for internalizing disorders such as major depression. Whether for clinical or research purposes, parents are also frequently asked to report on their children's experiences with alcohol and drugs. The purpose of this study was to analyze correspondence between adolescent and parent reports of adolescent substance use and abuse or dependence. In the current study, 591 subjects 12 to 17 years old were interviewed using the child version of the Semi-Structured Assessment for the Genetics of Alcoholism (C-SSAGA) as part of the Collaborative Study on the Genetics of Alcoholism (COGA). One parent was also interviewed about each adolescent using the parent version of the C-SSAGA. Sensitivities, specificities, and kappa coefficients were calculated to assess parental agreement with adolescent reports of lifetime substance use and Diagnostic and Statistical Manual of Mental Disorders-Third Revision substance abuse or dependence. The results indicate that parents are somewhat knowledgeable about their children's use of substances, particularly those that are used most commonly. For example, 55% of adolescents who had smoked cigarettes, 50% who had used alcohol, and 47% who had used marijuana had a parent who knew that they used. However, parents were less aware of substance-related problems experienced by their offspring, agreeing with adolescent reports only 27% of the time for diagnoses of alcohol abuse or dependence and 26% of the time for diagnoses of marijuana abuse or dependence. Parent reports added few cases of substance use for 12- to 13 year-olds and essentially no cases for 16- to 17-year-olds. Parent reports added a nominal number of diagnoses of substance abuse or dependence for older adolescents. Whether for clinical or research purposes, the results emphasize the importance of directly assessing adolescents regarding alcohol and other substance use disorders. Furthermore, investigators should consider the specific disorder(s) being investigated and the ages of the children being studied when determining whether to include parent reports as part of study design.

This study investigated the association of academic outcomes, romantic relationships, and substance use (tobacco, marijuana, cocaine) with alcohol dependence in a sample of Latino (N = 1,143) college students. Secondary data analysis was conducted on measures of grade point average in college, relationship satisfaction, drug use, and alcohol dependence. Latino college students who reported alcohol dependency had significant relational dissatisfaction and poor academic outcomes. Thus, lower grade point average and relationship dissatisfaction were associated with alcohol dependence. By focusing specifically on a Mexican American population, this study adds important information to current research regarding the commonality and differences across cultural groups regarding drug use and dependence and further clarifies the risk factors associated with substance use and dependency in a population that is vulnerable for at-risk behaviors. This study also offers insight into potential targets of treatment and intervention for this cultural group.

To examine among alcohol-dependent out-patient clients the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) total score and 'zones' suggested by the World Health Organization for defining levels of severity of alcohol use problems. Participants were classified into AUDIT zones (AUDIT total score = 8-15, 16-19, 20-40) and compared on measures of demographics, treatment goals, alcohol consumption, alcohol-related consequences, severity of dependence, physiological dependence, tolerance, withdrawal and biomarkers of alcohol use. Eleven out-patient academic clinical research centers across the United States. Participants Alcohol dependent individuals (n = 1335) entering out-patient treatment in the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study. The AUDIT was administered as part of an initial screening. Baseline measures used for concurrent validation included the Structured Clinical Interview for Diagnostic and Statistical Manual, 4th edition (DSM-IV) Disorders, the Alcohol Dependence Scale, the Drinker Inventory of Consequences, the Obsessive-Compulsive Drinking Scale, the University of Rhode Island Change Assessment, the Thoughts about Abstinence Scale, the Form-90, %carbohydrate-deficient transferrin and gamma-glutamyl transferase. Findings Indicators of severity of dependence and alcohol-related problems increased linearly with total score and differed significantly across AUDIT zones. The highest zone, with scores of 20 and above, was markedly different with respect to severity from the other two zones and members of this group endorsed an abstinence goal more strongly. The AUDIT total score is a brief measure that appears to provide an index of severity of dependence in a sample of alcohol-dependent individuals seeking out-patient treatment, extending its potential utility beyond its more traditional role as a screening instrument in general populations.

To compare providers' impressions of adolescents' level of substance use with diagnostic classifications from a structured diagnostic interview. Secondary analysis of data was conducted from a validation study of the CRAFFT substance abuse screening test of 14- to 18-year-old medical clinic patients (n = 533) and their corresponding medical care providers (n = 109) at an adolescent clinic affiliated with a large tertiary care pediatric hospital. Medical care providers completed a form that recorded their clinical impressions of patients' level of alcohol and drug involvement (none, minimal, problem, abuse, dependence) and demographic characteristics. The form included brief diagnostic descriptions for each level of use. After the medical visit, patients completed the Adolescent Diagnostic Interview (ADI), a structured diagnostic interview that yields diagnoses of abuse and dependence according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). On the basis of their past 12 months of alcohol and drug use on the ADI interview, adolescents were classified into 5 mutually exclusive diagnostic groups. "None" was defined by no reported use of alcohol or drugs during the past year. "Minimal use" was defined as use of alcohol or drugs but no report of any substance-related problems. "Problem use" was defined as reporting 1 or more substance-related problems but no diagnosis of abuse or dependence. "Abuse" was defined by meeting any 1 of 4 DSM-IV diagnostic criteria for either alcohol or drug abuse but no diagnosis of dependence. "Dependence" was defined by meeting any 3 of 7 diagnostic criteria for either alcohol or drug dependence, with or without a diagnosis of abuse. Proportions were compared using Fisher exact test. Agreement was assessed with the weighted kappa, and these analyses were stratified by substance used (ie, alcohol vs drug) and demographic characteristics. Sensitivity, specificity, and positive and negative predictive values were calculated from 2 x 2 tables. Compared with the criterion standard interview, providers identified significantly fewer patients with problem use and abuse and no patients with dependence. Of >100 patients whom the ADI classified with substance problem use, providers correctly identified 18. Of 50 patients who were classified with a diagnosis of alcohol or drug abuse, providers correctly identified 10. Of 36 patients who were classified with a diagnosis of alcohol or drug dependence, providers correctly identified none. For the 86 adolescents who were classified with a substance-related disorder (ie, abuse or dependence), providers' impressions were "none" (24.4%), "minimal use" (50%), "problem use" (15.1%), "abuse" (10.5%), and "dependence" (0%). There was only marginal agreement between providers' impressions and diagnoses related to alcohol use (kappa = .29), drug use (kappa = .31), and any substance use (kappa = .30). Kappa was not significantly affected by the patient's age, but it was by gender. Among boys, kappa was significantly higher for impressions of drug use versus alcohol use (kappa = .48 vs kappa = .27); and, among drug users, kappa was significantly higher among boys compared with girls (kappa = .48 vs kappa = .24). Kappa did not differ significantly across race/ethnicity subgroups, although there is a suggestive trend toward higher agreement for black non-Hispanic compared with white non-Hispanic adolescents (kappa = .35 vs kappa = .21). Kappa did not differ significantly on the basis of the visit type, but the size of this difference (kappa = .36 vs kappa = .24) suggests that the longer well-child visit yielded greater identification of substance-related pathology. Providers' impressions had a sensitivity of .63 for identifying use of alcohol or drugs. However, sensitivity was poor for identification of problem use (.14), abuse (.10), and dependence (0), whereas specificity and positive predictive values were high. Of the 86 adolescents with a diagnosis of abuse or dependence, 75.6% were correctly identified by providers as using substances; however, the level of use in 50% of these adolescents was reported by providers as minimal. In this study, clinical impressions of adolescents' alcohol/drug involvement underestimated substance-related pathology. When providers thought that use was present, there was a very high likelihood that a problem or disorder existed. The use of structured screening devices would likely improve identification of adolescents with substance-related pathology in primary care settings and should be considered for use with all adolescent patients, rather than only those who are perceived to be at higher risk.
[Sports, use of performance enhancing drugs and addiction. A conceptual and epidemiological review].
Franques, P; Auriacombe, M; Tignol, J
2001-11-01
Both the general public and non-sports medicine health professionals have recently been made aware of a large use of performance enhancing drugs among sports practicing subjects. It has been suggested that this behavior is similar to that of substance dependence. Also some have reported that practice of a sport could be in itself an addictive behavior. The main objective was to address the following question: is performance enhancing drug use in sports an addictive behavior? Methodology. We first reviewed the definition of performance enhancing drug use in sports and the diagnostic criteria of substance dependence as they are currently accepted and attempted to determine a possible common factor. Secondly we reviewed epidemiological data from the literature according to three approaches: Use of performance enhancing drugs is an important and increasing phenomenon among adolescents. It is sometimes associated to risk taking behaviors for health (syringe use and sharing). Competition participants are at increased risk (up to 20% according to some authors) and some substances (anabolic steroids) are also used by non-sports practicing individuals. It has not been shown that sports practicing subjects were more at risk of using addictive substances compared to non-sports practicing subjects. It is not established that practice of a sport is by itself a risk factor for substance use. However, it could be that a sub-group of individuals that practice certain types of sports in an intensive way, that use both performance enhancing drugs and addictive substances and that engage in health risk taking behaviors have an increased risk for developing a dependence syndrome to both addictive and performance enhancing drugs. This sub-group is even more at risk because some performance enhancing drugs (anabolic steroids) could increase the risk for occurrence of a substance dependence syndrome through neurobiological actions. Yet, the few available clinical studies show that at most only half of regular users actually meet criteria for dependence. Also, one study has reported an overrepresentation of sports professionals among patients seeking treatment for heroin addiction. The large majority of sports practicing subjects have no dependence to either performance enhancing or addictive drugs. However, a subgroup of individuals that practice sports intensely and makes use of both addictive and performance enhancing drugs appear to be at increased risk for developing a substance dependence syndrome.
Methylxanthines and drug dependence: a focus on interactions with substances of abuse.
Morelli, Micaela; Simola, Nicola
2011-01-01
This chapter examines the psychostimulant actions of methylxanthines, with a focus on the consequences of their excessive use. Consumption of methylxanthines is pervasive and their use is often associated with that of substances known to produce dependence and to have abuse potential. Therefore, the consequences of this combined use are taken into consideration in order to evaluate whether, and to what extent, methylxanthines could influence dependence on or abuse of other centrally active substances, leading to either amplification or attenuation of their effects. Since the methylxanthine that mostly influences mental processes and readily induces psychostimulation is caffeine, this review mainly focuses on caffeine as a prototype of methylxanthine-produced dependence, examining, at the same time, the risks related to caffeine use.

Similar to substance addictions, reward-related cognitive motivational processes, such as selective attention and positive memory biases, have been found in disordered gambling. Despite findings that individuals with substance use problems are biased to approach substance-related cues automatically, no study has yet focused on automatic approach tendencies for motivationally salient gambling cues in problem gamblers. We tested if moderate- to high-risk gamblers show a gambling approach bias and whether this bias was related prospectively to gambling behaviour and problems. Cross-sectional assessment study evaluating the concurrent and longitudinal correlates of gambling approach bias in moderate- to high-risk gamblers compared with non-problem gamblers. Online study throughout the Netherlands. Twenty-six non-treatment-seeking moderate- to high-risk gamblers and 26 non-problem gamblers community-recruited via the internet. Two online assessment sessions 6 months apart, including self-report measures of gambling problems and behaviour (frequency, duration and expenditure) and the gambling approach avoidance task, with stimuli tailored to individual gambling habits. Relative to non-problem gamblers, moderate- to high-risk gamblers revealed a stronger approach bias towards gambling-related stimuli than neutral stimuli (P = 0.03). Gambling approach bias was correlated positively with past-month gambling expenditure at baseline (P = 0.03) and with monthly frequency of gambling at follow-up (P = 0.02). In multiple hierarchical regressions, baseline gambling approach bias predicted monthly frequency positively (P = 0.03) and total duration of gambling episodes (P = 0.01) 6 months later, but not gambling problems or expenditure. In the Netherlands, relative to non-problem gamblers, moderate- to high-risk gamblers appear to have a stronger tendency to approach rather than to avoid gambling-related pictures compared with neutral ones. This gambling approach bias is associated concurrently with past-month gambling expenditure and duration of gambling and has been found to predict persistence in gambling behaviour over time. © 2017 Society for the Study of Addiction.

Adult attention deficit hyperactivity disorder (ADHD) shows a robust association with alcohol and cannabis misuse, and these relationships are expressed differently in males and females. Manifestation of specific ADHD symptom profiles, even in the absence of the full disorder, may also be related to problems with alcohol and cannabis, although these relationships have not been investigated in epidemiological studies. To address this question, we studied the sex-specific associations of ADHD symptomatology with problematic alcohol and cannabis use in a representative sample of adults aged 18 years and older residing in Ontario, Canada. Data were obtained from the Centre for Addiction and Mental Health Monitor, an ongoing cross-sectional telephone survey, between January 2011 and December 2013. Respondents (n = 5080) reported on current ADHD symptomatology, measured using the Adult ADHD Self-Report Version 1.1 Screener (ASRS-V1.1) and four additional items, and alcohol and cannabis use, which were measured using the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), respectively. Logistic regression analyses were conducted in men and women to test the association of each ADHD symptom cluster (hyperactivity, inattentiveness, impulsivity) with problematic alcohol and cannabis use. After controlling for age, education, and comorbid internalizing and externalizing psychopathology, hyperactive symptoms were associated with problematic alcohol use in both men and women and with problematic cannabis use in men. Impulsive symptoms were independently associated with problematic cannabis use in men. By contrast, inattentive symptomatology predicted problems with alcohol and cannabis only in women. In all models, age was negatively associated with substance misuse and externalizing behavior was positively correlated and the strongest predictor of hazardous alcohol and cannabis use. ADHD symptom expression in adulthood is related to concurrent hazardous use of alcohol and cannabis. Distinctive ADHD symptom profiles may confer increased risk for substance misuse in a sex-specific manner.

Labour market disengagement among youths has lasting negative economic and social consequences, yet is poorly understood. We compared four types of work-related self-perceptions, as well as vulnerability to mental health and substance abuse problems, among youths not in education, employment or training (NEET) and among their peers. Participants were from the Environmental Risk (E-Risk) longitudinal study, a nationally representative UK cohort of 2,232 twins born in 1994-1995. We measured commitment to work, job-search effort, professional/technical skills, 'soft' skills (e.g. teamwork, decision-making, communication), optimism about getting ahead, and mental health and substance use disorders at age 18. We also examined childhood mental health. At age 18, 11.6% of participants were NEET. NEET participants reported themselves as committed to work and searching for jobs with greater diligence than their non-NEET peers. However, they reported fewer 'soft' skills (B = -0.98, p < .001) and felt less optimistic about their likelihood of getting ahead in life (B = -2.41, p < .001). NEET youths also had higher rates of concurrent mental health and substance abuse problems, but these did not explain the relationship with work-related self-perceptions. Nearly 60% of NEET (vs. 35% of non-NEET) youths had already experienced ≥1 mental health problem in childhood/adolescence. Associations of NEET status with concurrent mental health problems were independent of pre-existing mental health vulnerability. Our findings indicate that while NEET is clearly an economic and mental health issue, it does not appear to be a motivation issue. Alongside skills, work-related self-perceptions and mental health problems may be targets for intervention and service provision among this high-risk population. © 2015 Association for Child and Adolescent Mental Health.
How should we revise diagnostic criteria for substance use disorders in the DSM-V?
Martin, Christopher S; Chung, Tammy; Langenbucher, James W
2008-08-01
This article reviews literature on the validity and performance characteristics of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) diagnostic criteria for substance use disorders (SUDs) and recommends changes in these criteria that should be considered for the next edition of the DSM (DSM-V). Substantial data indicate that DSM-IV substance abuse and substance dependence are not distinct categories and that SUD criteria are best modeled as reflecting a unidimensional continuum of substance-problem severity. The conceptually and empirically problematic substance abuse diagnosis should be abandoned in the DSM-V, with substance dependence defined by a single set of criteria. Data also indicate that various individual SUD criteria should be revised, dropped, or considered for inclusion in the DSM-V. The DSM-V should provide a framework that allows the integration of categorical and dimensional approaches to diagnosis. Important areas for further research are noted.

Thermal Entanglement in XXZ Heisenberg Model for Coupled Spin-Half and Spin-One Triangular Cell

In this paper, we investigate the thermal entanglement of two-spin subsystems in an ensemble of coupled spin-half and spin-one triangular cells, (1/2, 1/2, 1/2), (1/2, 1, 1/2), (1, 1/2, 1) and (1, 1, 1) with the XXZ anisotropic Heisenberg model subjected to an external homogeneous magnetic field. We adopt the generalized concurrence as the measure of entanglement which is a good indicator of the thermal entanglement and the critical points in the mixed higher dimensional spin systems. We observe that in the near vicinity of the absolute zero, the concurrence measure is symmetric with respect to zero magnetic field and changes abruptly from a non-null to null value for a critical magnetic field that can be signature of a quantum phase transition at finite temperature. The analysis of concurrence versus temperature shows that there exists a critical temperature, that depends on the type of the interaction, i.e. ferromagnetic or antiferromagnetic, the anisotropy parameter and the strength of the magnetic field. Results show that the pairwise thermal entanglement depends on the third spin which affects the maximum value of the concurrence at absolute zero and at quantum critical points.

For American college students, alcohol and cigarette use are important health concerns, and employment concurrent with school attendance is on the rise. Given the lifelong importance of employment and substance use trajectories begun in college, parsing out the relationship between the two is meaningful. This study's purpose is to determine whether employment during college is associated with substance use. Cross-sectional associations between employment (work hours, earnings) and substance use (drinking frequency, drinking quantity, smoking frequency) were estimated using partial proportional odds models in a sample of N = 1457 freshmen attending a large, public 4-year university in 2011, after accounting for demographics, personality, social environment, and parental influences. Working 10 more hours and earning $50 more per week as a freshman had modest positive associations with higher smoking frequency and with moderate drinking frequency and quantity prior to adjustment. After adjustment, work hours remained modestly associated with moderate drinking frequency and quantity. No adjusted associations were found among employment measures and smoking or between weekly earnings and drinking frequency. Different relationships emerged for moderate versus heavy alcohol use frequency and quantity. Both employment and substance use are commonplace among college freshmen. After extensive controls for potential confounders, the relationship between the two appears modest. Employment may yet play a role in college student substance use, but work hours and earnings are likely only small parts of a larger web of influences on drinking and smoking.

Substance abuse disorders in nurses.
Griffith, J
1999-01-01
Substance abuse is a serious concern in the profession of nursing. The American Nurses Association (1997) estimates that 10% to 20% of nurses have substance abuse problems, and that 6% to 8% of registered nurses are impaired due to their abuse of alcohol and other drugs. Chemical dependency is considered a disease that requires treatment. Early identification and treatment of the chemically dependent nurse is important for the safety of the public and for the well-being of the nurse and her profession. This article addresses substance abuse from a biopsychosocial perspective, and includes a description of an approach to treatment and suggestions for the role of nursing administration.
Treating patients with bipolar disorder and substance dependence: lessons learned.
Weiss, Roger D
2004-12-01
Although bipolar disorder is the Axis I psychiatric disorder associated with the highest rate of co-occurring substance use disorders, little research has focused on treatments specifically designed for these patients. The author and his colleagues have developed and studied Integrated Group Therapy (IGT) for this population. This paper describes common themes that have emerged in carrying out IGT for patients with bipolar disorder and substance dependence. These include the strong emphasis on depression, as opposed to mania; the predominance of hopelessness; specific patterns of medication noncompliance; and the implications of patients' labeling their substance use as self-medication. Therapeutic aspects involved in addressing these themes are discussed.

Risk factors among adolescent substance abusers have been shown to correlate with substance use severity. Characteristics related to severity, such as demographic and family factors, peer influences, psychiatric co-morbidity and HIV risk behaviors, are examined for a sample of adolescent cannabis users entering treatment. These data are from a clinical trial study utilizing blocked random assignment of clients to one of five treatment conditions. The study targeted adolescents entering outpatient treatment for primarily cannabis abuse or dependence. Treatment and research facilities in four metropolitan areas of the US were used to recruit study participants. Treatment was delivered in outpatient drug-free settings. Participants were 600 clients, ages 12-18, admitted to outpatient substance abuse treatment programs for cannabis problems, 96% with DSM-IV diagnoses of substance abuse or dependence, with the remaining 4% having at least one symptom of dependence plus significant problems indicating need for treatment. The Global Appraisal of Individual Needs (GAIN) was used to collect the information presented in this paper. The GAIN incorporates DSM-IV criteria for substance use disorders, conduct disorder and attention deficit hyperactivity disorder, as well as dimensional (scale) measures for physical and mental health. All participants reported at least one symptom of substance use disorders, and 46% met the DSM-IV criteria for substance dependence, while 50% met criteria for a diagnosis of abuse. Only 20% of the participants perceived any need for help with problems associated with their drug or alcohol use. Clients participating in the study typically presented multiple problems at treatment entry, most often including conduct disorder, attention deficit hyperactivity disorder (ADHD), internal (mental) distress, and physical health distress. The co-occurrence of conduct disorder and ADHD was found in 30% of the sample. Clients meeting criteria for substance dependence tended to have more co-occurring problems and significantly less denial at admission. The characteristics of this sample exemplify the complex nature of adolescent substance use and abuse among adolescents entering outpatient treatment programs. Patterns of co-occurring problems are at rates comparable to those found in other clinical studies. Those with more severe substance use disorders tend to manifest more problems of social functioning, more mental health problems, and physical health problems. Implications of these findings are discussed in terms of treatment needs, challenges, and prognostic implications.

The purpose of this study is to explore narcissistic and prosocial behaviors as reported by adolescents with and without substance dependency disorder (SDD). This study employs a quasi-experimental design using SDD adolescents compared with two normative samples of adolescents. In comparison to normative adolescents, adolescents with SDD were strongly distinguished by overt narcissistic behaviors and less monetary giving. Levels of narcissistic and prosocial behaviors among adolescents with SDD suggest a connection between self-centeredness and addiction. Results also suggest volunteerism as a potential option to counter narcissism in substance dependent adolescents. PMID:22544995
Concurrent sexual partnerships among married Zimbabweans – implications for HIV prevention
Mugweni, Esther; Pearson, Stephen; Omar, Mayeh
2015-01-01
Background Concurrent sexual partnerships play a key role in sustaining the HIV epidemic in Zimbabwe. Married couples are at an increased risk of contracting HIV from sexual networks produced by concurrent sexual partnerships. Addressing these partnerships is an international HIV prevention priority. Methods Our qualitative study presents the socioeconomic factors that contribute to the occurrence of concurrent sexual partnerships among married people in Zimbabwe. We conducted 36 in-depth interviews and four focus group discussions with married men and women in Zimbabwe in 2008 to understand the organizations of concurrent sexual partnerships. Data were analyzed using framework analysis. Results Our study indicates that relationship dissatisfaction played a key role in the engagement of concurrent sexual partnerships. Depending on the source of the dissatisfaction, there were four possible types of concurrent sexual relationships that were formed: sex worker, casual partner, regular girlfriend or informal polygyny which was referred to as “small house”. These relationships had different levels of intimacy, which had a bearing on practicing safer sex. Participants described three characteristics of hegemonic masculinity that contributed to the sources of dissatisfaction leading to concurrent sexual activity. Similarly, various aspects of emphasized femininity were described as creating opportunities for the occurrence of concurrent sexual relationships. Economic status was also listed as a factor that contributed to the occurrence of concurrent sexual partnerships. Conclusion Marital dissatisfaction was indicated as a contributing factor to the occurrence of concurrent sexual relationships. There were several reports of satisfying marital relationships in which affairs did not occur. Lessons from these marriages can be made part of future HIV prevention interventions targeted at preventing concurrent sexual partnerships by married couples. PMID:26491372

Substance use and abuse, which includes alcohol use, alcohol dependence, drug use, and drug dependence, inflicts a substantial toll on Americans. Although studies have demonstrated the protective effect of social support, such as religious participation and via marriage, understanding their influence on racial and ethnic minorities is limited. Thus, the aim of this study is to assess the impact of social support on substance use and abuse in racial and ethnic minorities. The Collaborative Psychiatric Epidemiology Surveys, sponsored by the National Institute of Mental Health, a repository of race, ethnicity, and mental health data, was leveraged to develop four models using multivariate analysis, specifically logistic regression to estimate the probability of meeting the criteria for substance use and abuse. Racial and ethnic minorities were found to have lower rates of substance use and abuse compared to Whites, and foreign-born individuals were consistently less likely to use or abuse substances compared to American-born minorities. Mental health conditions were highly associated with substance use and abuse, and social support by way of religious participation and marriage was protective against substance use and abuse. In racial and ethnic minorities, nativity and social support were protective against substance use and abuse; however, these protective factors did not completely eliminate risk. Thus, although race and ethnicity are important to understanding health outcomes and health behaviors, such as substance use and abuse, it is the intersection of multiple factors, representing internal and external forces, which may be more informative and offer a more comprehensive picture of the landscape influencing drug and alcohol use and dependence. Targeted interventions should consider leveraging religious spaces and bilingual materials when attempting to reach racial and ethnic minorities.

Marijuana (MJ) use and HIV infection are both associated with neurocognitive deficits, yet there is little research to date examining their interactions, specifically how they pertain to procedural learning (PL). We examined a sample of 86 individuals with a history of dependence for multiple substances who underwent a comprehensive evaluation including measures of mental health, substance use history, and three measures of PL: the photoelectric Rotary Pursuit Task (RPT), the Star Mirror Tracing Task (SMT), and the Weather Prediction Task (WPT). We found that a positive HIV serostatus and a history of marijuana dependence were both independently associated with overall poorer performance on the SMT and RPT in this sample of individuals with a history of dependence for multiple substances. Rate of improvement across trial blocks did not differ as a function of HIV serostatus or history of marijuana dependence. Although we found no significant HIV × MJ interaction for any of the PL tasks, we did observe evidence of additive negative effects from HIV and a history of marijuana dependence on overall performance on the SMT and RPT, but not the WPT. The findings suggest that complex motor skills are adversely affected among abstinent polysubstance users with a history of marijuana dependence and that such deficits are compounded by HIV.

Objective To examine three aspects of adolescent cannabis problems: 1) do DSM-IV cannabis abuse and dependence criteria represent two different levels of severity of substance involvement, 2) to what degree do each of the 11 abuse and dependence criteria assess adolescent cannabis problems, and 3) do the DSM-IV items function similarly across different adolescent populations? Method We examined 5587 adolescents aged 11–19, including 615 youth in treatment for substance use disorders, 179 adjudicated youth, and 4793 youth from the community. All subjects were assessed with a structured diagnostic interview. Item response theory was utilized to analyze symptom endorsement patterns. Results Abuse and dependence criteria were not found to represent different levels of severity of problem cannabis use in any of the samples. Among the 11 abuse and dependence criteria, Problems cutting down and Legal problems were the least informative for distinguishing problem users. Two dependence criteria and three of the four abuse criteria indicated different severities of cannabis problems across samples. Conclusions We found little evidence to support the idea that abuse and dependence are separate constructs for adolescent cannabis problems. Furthermore, certain abuse criteria may indicate severe substance problems while specific dependence items may indicate less severe problems. The abuse items in particular need further study. These results have implications for the refinement of the current substance use disorder criteria for DSM-V. PMID:18176333

1. The action of substance P (SP) on the release of gamma-aminobutyric acid (GABA) and acetylcholine (ACh) and on contraction were studied in strips of the guinea-pig urinary bladder. Substance P induced a dose-dependent contraction of strips of guinea-pig urinary bladder (EC50 = 1.2 x 10(-9) M). This contraction was not altered by tetrodotoxin, but with a dose of 10(-9) M and less, there was a complete inhibition by 10(-6) M) atropine. Contractions initiated by 3 x 10(-9) M) SP or more were partly inhibited by atropine. The EC50 value of substance P in the presence of atropine was 7.0 x 10(-9) M. 2. Substance P induced a Ca2+-dependent and tetrodotoxin-resistant release of [3H]-acetylcholine (ACh) from strips of urinary bladder preloaded with [3H]-choline (EC50 = 4.9 x 10(-10) M), and this release was antagonized by [D-Pro2,D-Trp7,9] substance P. 3. Bicuculline increased the substance P-induced contraction and the release of [3H]-ACh from the strips. 4. Substance P induced a Ca2+-dependent and tetrodotoxin-sensitive release of [3H]-gamma-aminobutyric acid (GABA) from strips preloaded with [3H]-GABA (EC50 = 2.6 x 10(-9) M), and this release was antagonized by [D-Pro2,D-Trp7,9] substance P. 5. Therefore, substance P appears to exert excitatory effects on the contractility of urinary bladder predominantly by stimulating its own receptor located on the cholinergic nerve terminals. GABA released by substance P inhibits stimulation of the cholinergic neurone. However, the direct action of substance P on the cholinergic neurone is more potent that the indirect action via GABA release. PMID:2479440
Assessment of the Tobacco Dependence Screener Among Smokeless Tobacco Users.
Mushtaq, Nasir; Beebe, Laura A
2016-05-01
Variants of the Fagerström Tolerance Questionnaire and Fagerström Test for Nicotine Dependence (FTND) are widely used to study dependence among smokeless tobacco (ST) users. However, there is a need for a dependence measure which is based on the clinical definition of dependence and is easy to administer. The Tobacco Dependence Screener (TDS), a self-administered 10-item scale, is based on the Diagnostic and Statistical Manual, fourth edition (DSM-IV) and ICD-10 definitions of dependence. It is commonly used as a tobacco dependence screening tool in cigarette smoking studies but it has not been evaluated for dependence in ST users. The purpose of this study is to evaluate the TDS as a measure of tobacco dependence among ST users. Data collected from a community-based sample of exclusive ST users living in Oklahoma (n = 95) was used for this study. TDS was adapted to be used for ST dependence as the references for smoking were changed to ST use. Concurrent validity and reliability of TDS were evaluated. Salivary cotinine concentration was used as a criterion variable. Overall accuracy of the TDS was assessed by receiver's operating characteristic (ROC) curve and optimal cutoff scores for dependence diagnosis were evaluated. There was no floor or ceiling effect in TDS score (mean = 5.42, SD = 2.61). Concurrent validity of TDS as evaluated by comparing it with FTND-ST was affirmative. Study findings showed significant association between TDS and salivary cotinine concentration. The internal consistency assessed by Cronbach's alpha indicated that TDS had acceptable reliability (α = 0.765). TDS was negatively correlated with time to first chew/dip and positively correlated with frequency (number of chews per day) and years of ST use. Results of logistic regression analysis showed that at an optimal cutoff score of TDS 5+, ST users classified as dependent had significantly higher cotinine concentration and FTND-ST scores. TDS demonstrated acceptable reliability and concurrent validity among ST users. These findings are consistent with the results of previous cigarette smoking studies evaluating TDS. A self-administered tobacco dependence measure for ST users based on a clinical definition of dependence is an effective tool in research setting. ST dependence research is still evolving. This is the first study of the TDS among ST users providing preliminary evidence about some of the psychometric properties of the scale. Similar to cigarette smokers, TDS is an effective measure of ST dependence. Study showed moderate reliability and affirmative concurrent validity of the TDS among ST users. © The Author 2015.

The relationship between substance use disorders and criminal activity is strong, and one that is not easily resolved in the criminal justice system. A better understanding of personality traits among substance misusers who commit offences could support better treatment efforts. The aim of this study is to explore associations between the psychopathology of people addicted to substances who have also committed crimes. We recruited 263 substance-dependent individuals (80% male, 20% female) from a cohort of people attending regional community services in Italy. They all completed an extensive evaluation of their current mental health and personality traits. Their official criminal records were obtained, and the psychopathology of those who had a criminal record compared with those who did not. The criminal group was more likely to perceive the external world as hostile and to consider others as responsible for their own problems and difficulties; in addition, substance-dependent individuals with criminal records showed more personality traits within the psychopathy range and fewer in the dependent personality range than the substance abusers who had never committed crimes. These findings allow us to hypothesise that substance abusers who also have criminal convictions may have a specific personality profile. If further research were to confirm this, then it could have important implications for identifying people for particular treatment pathways and developing more effective treatments.

Given the clinical and public health significance of substance disorders and the need to identify their early risk factors, we examined the association of childhood attention-deficit/hyperactivity disorder (ADHD) with substance use (e.g., nicotine, alcohol) and abuse/dependence outcomes (nicotine, alcohol, marijuana, cocaine, other). To strengthen a potential causal inference, we meta-analyzed longitudinal studies that prospectively followed children with and without ADHD into adolescence or adulthood. Children with ADHD were significantly more likely to have ever used nicotine and other substances, but not alcohol. Children with ADHD were also more likely to develop disorders of abuse/dependence for nicotine, alcohol, marijuana, cocaine, and other substances (i.e., unspecified). Sex, age, race, publication year, sample source, and version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) used to diagnose ADHD did not significantly moderate the associations with substance outcomes that yielded heterogeneous effect sizes. These findings suggest that children with ADHD are significantly more likely to develop substance use disorders than children without ADHD and that this increased risk is robust to demographic and methodological differences that varied across the studies. Finally, few studies addressed ADHD and comorbid disruptive behavior disorders (DBD), thus preventing a formal meta-analytic review. However, we qualitatively summarize the results of these studies and conclude that comorbid DBD complicates inferences about the specificity of ADHD effects on substance use outcomes. PMID:21382538
Concurrent Treatment of Substance Use and PTSD.
Flanagan, Julianne C; Korte, Kristina J; Killeen, Therese K; Back, Sudie E
2016-08-01
Substance use disorders (SUD) and posttraumatic stress disorder (PTSD) are chronic, debilitating conditions that frequently co-occur. Individuals with co-occurring SUD and PTSD suffer a more complicated course of treatment and less favorable treatment outcomes compared to individuals with either disorder alone. The development of effective psychosocial and pharmacological interventions for co-occurring SUD and PTSD is an active and critically important area of investigation. Several integrated psychosocial treatments for co-occurring SUD and PTSD have demonstrated promising outcomes. While recent studies examining medications to treat co-occurring SUD and PTSD have yielded encouraging findings, there remain substantial gaps in the evidence base regarding the treatment of co-occurring SUD and PTSD. This review will summarize the findings from clinical trials targeting a reduction in SUD and PTSD symptoms simultaneously. These results may improve our knowledge base and subsequently enhance our ability to develop effective interventions for this complex comorbid condition.
The Client Satisfaction Questionnaire: psychometric properties in a Dutch addict population.
De Wilde, Eveline F; Hendriks, Vincent M
2005-01-01
The aim of this study is to investigate psychometric properties of the Client Satisfaction Questionnaire (CSQ-8) in a Dutch substance abuse population. The CSQ-8 and the Mental Health Thermometer (the standard Dutch satisfaction instrument) were sent to 927 patients of a Dutch substance abuse treatment centre. (response rate 28.3%; n = 262). Data were compared on several variables (i.e., age, gender, ethnicity, treatment type). For a subgroup of responders (n = 84), data were compared with pre-treatment problem severity and treatment need (the European Addiction Severity Index). Both internal consistency and concurrent validity were found to be high. Only treatment type had significant effects on CSQ-8 satisfaction scores. Scores were negatively skewed. The CSQ-8 is as suitable an instrument to be used in addict populations, as it is in other populations. (c) 2005 S. Karger AG, Basel
[Abuse, dependence and intoxication of substances].
Wada, Kiyoshi
2015-09-01
As for substance-related disorders, there were several differences between ICD-10 and DSM-IV, however, the concept of "dependence" had been essential for both criteria. DSM-5 published in 2013 had erased dependence. This confuses us. It is important to recognize dependence again. "Abuse" is the self-intake behavior of drug against the social norms. Repeated abuse results in dependence. Dependence is a state of loss of control against drug use due to craving. Abuse can produce "acute intoxication", and repeated abuse under dependence can produce "chronic intoxication". It is important to understand abuse, dependence and "intoxication" based on their relationship from the point of time course.
Caffeine use and dependence in adolescents: one-year follow-up.
Oberstar, Joel V; Bernstein, Gail A; Thuras, Paul D
2002-01-01
The objectives were to conduct a 1-year follow-up of daily caffeine-using adolescents to further describe caffeine dependence symptoms and to determine whether caffeine dependence is associated with other substance dependence disorders. Twenty-one of 36 (58.3%) adolescents who participated in a study of caffeine dependence returned for follow-up. The previous study was a case series of adolescents who consumed caffeine daily and met some Diagnostic and Statistical Manual of Mental Disorders (fourth edition) substance dependence criteria as applied to caffeine. At follow-up, caffeine consumption from beverages was 179.9 +/- 151.8 mg/day. Of the 21 teenagers, 23.8% (n = 5) met criteria for caffeine dependence. Four of these participants developed caffeine dependence during the follow-up period. Other substance dependence disorders were not overrepresented in the caffeine dependent group compared to the caffeine nondependent group. The most commonly reported withdrawal symptoms in dependent teenagers (at baseline and follow-up combined) were feeling drowsy/tired, fatigued, or sluggish/slowed down (83.3% each) and headache (75.0%). Caffeine dependence occurs in some adolescents who drink caffeine daily and is marked by symptoms similar to those found in adults.

Background Linkages between intrauterine exposures to cocaine and marijuana and adolescents’ problematic substance use have not been fully delineated. Methods Prospective longitudinal study with assessors unaware of intrauterine exposure history followed 157 urban participants from birth until late adolescence. Level of intrauterine exposures was identified by mother's report and infant’s meconium. Problematic substance use, identified by the Voice Diagnostic Interview Schedule for Children (V-DISC) or the Audio Computer Assisted Self-Interview (ACASI) and urine assay, was a composite encompassing DSM-IV indication of tolerance, abuse, and dependence on alcohol, marijuana, and tobacco and any use of cocaine, glue, or opiates. Results Twenty percent (32/157) of the sample experienced problematic substance use by age 18 years, of whom the majority (22/157) acknowledged abuse, tolerance or dependence on marijuana with or without other substances. Structural equation models examining direct and indirect pathways linking a Cox survival model for early substance initiation to a logistic regression models found effects of post-natal factors including childhood exposure to violence and household substance use, early youth substance initiation, and ongoing youth violence exposure contributing to adolescent problematic substance use. Conclusion We did not identify direct relationships between intrauterine cocaine or marijuana exposure and problematic substance use, but did find potentially modifiable post-natal risk factors also noted to be associated with problematic substance use in the general population including earlier substance initiation, exposure to violence and to household substance use.

Proposed International Classification of Diseases, 11th edition (ICD-11), criteria for substance use disorder (SUD) radically simplify the algorithm used to diagnose substance dependence. Major differences in case identification across DSM and ICD impact determinations of treatment need and conceptualizations of substance dependence. This study compared the draft algorithm for ICD-11 SUD against DSM-IV, DSM-5, and ICD-10, for alcohol and cannabis. Adolescents (n = 339, ages 14 to 18) admitted to intensive outpatient addictions treatment completed, as part of a research study, a Structured Clinical Interview for DSM SUDs adapted for use with adolescents and which has been used to assess DSM and ICD SUD diagnoses. Analyses examined prevalence across classification systems, diagnostic concordance, and sources of diagnostic disagreement. Prevalence of any past-year proposed ICD-11 alcohol or cannabis use disorder was significantly lower compared to DSM-IV and DSM-5 (ps < 0.01). However, prevalence of proposed ICD-11 alcohol and cannabis dependence diagnoses was significantly higher compared to DSM-IV, DSM-5, and ICD-10 (ps < 0.01). ICD-11 and DSM-5 SUD diagnoses showed only moderate concordance. For both alcohol and cannabis, youth typically met criteria for an ICD-11 dependence diagnosis by reporting tolerance and much time spent using or recovering from the substance, rather than symptoms indicating impaired control over use. The proposed ICD-11 dependence algorithm appears to "overdiagnose" dependence on alcohol and cannabis relative to DSM-IV and ICD-10 dependence, and DSM-5 moderate/severe use disorder, generating potential "false-positive" cases of dependence. Among youth who met criteria for proposed ICD-11 dependence, few reported impaired control over substance use, highlighting ongoing issues in the conceptualization and diagnosis of SUD.

The microwave absorption of certain water soluble polymers (polyethylene glycol, polyvinyl pyrrolidone, proteins, and DNA) in solution is composed of three parts: absorption in the free water, absorption in the substance, and absorption in the hydration layer. Ethanol, sucrose, glycerol, and sodium acetate, which form weak hydrogen bonds or have an ionic nature in aqueous solutions, also have microwave absorption signatures similar to polymers that form hydration layers. The frequency-dependent absorption of the free water and of the hydration layer water is described by a simple Debye relaxation model. The absorption per unit sample volume attributable to the hydration layer is solute concentration dependent, and a simple model is used to describe the dependence. The hydration-layer relaxation time was found to vary from substance to substance and with solute concentration. The relaxation time was also found to be independent of solute length.
Days with pain and substance use disorders: is there an association?

We investigated possible associations between pain frequency and the 5 most common substance use disorders: alcohol abuse/dependence, cocaine abuse/dependence, methamphetamine abuse/dependence, opioid abuse/dependence, and marijuana abuse/dependence. We used data from the Rural Stimulant Study, a longitudinal (7 waves), observational study of at-risk stimulant users (cocaine and methamphetamine) in Arkansas and Kentucky (n=462). In fixed-effects logistic regression models, we regressed our measures of substance use disorders on the number of days with pain in the past 30 days and depression severity. Time periods when individuals had 1 to 15 days [odds ratio (OR)=1.85, P<0.001] or 16+ days (OR=2.18, P<0.001) with pain in the past 30 days were more likely to have a diagnosis of alcohol abuse/dependence, compared with time periods when individuals had no days with pain. Compared with time periods when individuals had no pain days in the past 30 days, time periods when individuals had 16+ pain days were more likely to have a diagnosis of opioid abuse/dependence (OR=3.32, P=0.02). Number of days with pain was not significantly associated with other substance use disorders. Pain frequency seems to be associated with an increased risk for alcohol abuse/dependence and opioid abuse/dependence in this population, and the magnitude of the association is medium to large. Further research is needed to investigate this in more representative populations and to determine causal relationships.

Combination packages for HIV prevention can leverage the effectiveness of biomedical and behavioural elements to lower disease incidence with realistic targets for individual and population risk reduction. We investigated how sexual network structures can maximise the effectiveness of a package targeting sexually active adults in sub-Saharan Africa (SSA) with intervention components for medical male circumcision (MMC) and sexual partnership concurrency (having >1 ongoing partner). Network-based mathematical models of HIV type 1 (HIV-1) transmission dynamics among heterosexual couples were used to explore how changes to MMC alone and in combination with changes to concurrency impacted endemic HIV-1 prevalence and incidence. Starting from a base model parameterised from empirical data from West Africa, we simulated the prevalence of circumcision from 10% to 90% and concurrency was modelled at four discrete levels corresponding to values observed across SSA. MMC and concurrency could contribute to the empirical variation in HIV-1 disease prevalence across SSA. Small reductions in concurrency resulted in large declines in HIV-1 prevalence. Scaling up circumcision in low-concurrency settings yields a greater relative benefit, but the absolute number of infections averted depends on both the circumcision coverage and baseline incidence. Epidemic extinction with this package will require substantial scale-up of MMC in low-concurrency settings. Dynamic sexual network structure should be considered in the design and targeting of MMC within combination HIV-1 prevention packages. Realistic levels of coverage for these packages within southern Africa could lead to a reduction of incidence to the low levels observed in western Africa, and possibly, epidemic extinction.

Do anorectic men share personality traits with opiate dependent men? A case-control study.
Abbate-Daga, Giovanni; Amianto, Federico; Rogna, Lorenzo; Fassino, Secondo
2007-01-01
Eating disorders (ED) and substance use disorders (SUD) display clinical and psychodynamic analogies. The co-diagnosis of a substance use disorder in male ED patients is frequent. Nevertheless, knowledge about the mutual predisposing factors or personality analogies is currently scarce and hypotheses are controversial. The Temperament and Character Inventory (TCI) was used to assess 21 anorectic men, 79 heroin-dependent men, and 75 control men matched for age and education. Anorectic and opiate-addicted patients displayed higher Harm Avoidance and lower Self-directedness and Cooperativeness. Anorectic men displayed lower Reward Dependence and higher Persistence. Opiate addicts had higher Novelty Seeking and Self-transcendence. Anorectic and heroine-dependent subjects share personality traits related to anxiety, fearfulness and antisocial features. Nevertheless, the personality profile does not completely overlap and this could influence the choice of the "substance" of abuse and the related clinical differences between anorexia and heroin dependence.

Despite evidence of substantial comorbidity between psychiatric disorders and substance involvement, the extent to which common genetic factors contribute to their co-occurrence remains understudied. In the current study, we tested for associations between polygenic risk for psychiatric disorders and substance involvement (i.e., ranging from ever-use to severe dependence) among 2573 non-Hispanic European-American participants from the Study of Addiction: Genetics and Environment. Polygenic risk scores (PRS) for cross-disorder psychopathology (CROSS) were generated based on the Psychiatric Genomics Consortium's Cross-Disorder meta-analysis and then tested for associations with a factor representing general liability to alcohol, cannabis, cocaine, nicotine, and opioid involvement (GENSUB). Follow-up analyses evaluated specific associations between each of the five psychiatric disorders which comprised CROSS-attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (AUT), bipolar disorder (BIP), major depressive disorder (MDD), and schizophrenia (SCZ)-and involvement with each component substance included in GENSUB. CROSS PRS explained 1.10% of variance in GENSUB in our sample (p < 0.001). After correction for multiple testing in our follow-up analyses of polygenic risk for each individual disorder predicting involvement with each component substance, associations remained between: (A) MDD PRS and non-problem cannabis use, (B) MDD PRS and severe cocaine dependence, (C) SCZ PRS and non-problem cannabis use and severe cannabis dependence, and (D) SCZ PRS and severe cocaine dependence. These results suggest that shared covariance from common genetic variation contributes to psychiatric and substance involvement comorbidity.
Substance abuse and dependence in the hospital workplace: detection and handling.
Ossi, J
1991-01-01
A hospital can take many avenues in dealing with an employee or professional who is impaired by substance abuse or dependence. The most difficult aspect of dealing with the problem is detection. Fortunately, increasing public awareness and concern regarding workplace substance abuse is forcing legislators to address the issue and expose the problem. The legislative response appears to be geared toward treatment and education rather than punishment, which in the opinion of this author is a desirable approach. The pharmacy department can be a valuable asset to the hospital risk manager in detecting diversion of controlled substances and educating employees as to the clinical signs and symptoms of impairment.

Existing tools for measuring blood-borne virus (BBV) and sexually transmitted infection (STI) transmission risk behaviours in substance use interventions have limited capacity to assess risk behaviours across varied social, cultural and epidemiological contexts; have not evolved alongside HIV treatment and prevention innovations; or accounted for sexual contexts of drug use including among a range of lesbian, gay, bisexual, transgender, intersex and queer (LGBTIQ) sub-communities. The Substance Use and Sex Index (SUSI) is a new brief, simple tool being developed to assess change in HIV and STI risk behaviours for substance use treatment studies. A 26-item questionnaire was piloted online among community volunteers (n = 199). Concurrent and predictive validity were assessed against risk-taking (RT-18) and STI testing items (Gay Community Periodic Surveys). The developed scale comprised nine items measuring: condomless penile (anal or vaginal) sex, unprotected oral sex, shared toy use, bloodplay, chemsex (consumption of drugs for the facilitation of sex), trading sex for drugs, being 'too out of it' to protect self, injecting risk and group sex. Factor-analytic approaches demonstrated that items met good fit criteria for a single scale. Significant, moderate magnitude, positive relationships were identified between total SUSI score and both RT-18 risk-taking and recent STI testing. Qualitative feedback underscored the importance of culturally-embedded question formulation. The results support the conceptual basis for the instrument, highlighting the need for further scale content refinement to validate the tool and examine sensitivity to change. SUSI is a step towards improving outcome measurement of HIV/BBV/STI transmission risk behaviours in substance use treatment studies with greater inclusiveness of experiences across different population groups.

To evaluate and characterize the structure of temporal patterns of depression, smoking, unhealthy alcohol use, and other substance use among individuals receiving medical care, and to inform discussion about whether integrated screening and treatment strategies for these conditions are warranted. Using the Veterans Aging Cohort Study (VACS) we measured depression, smoking, unhealthy alcohol use and other substance use (stimulants, marijuana, heroin, opioids) and evaluated which conditions tended to co-occur within individuals, and how this co-occurrence was temporally structured (i.e. concurrently, sequentially, or discordantly). Current depression was associated with current use of every substance examined with the exception of unhealthy alcohol use. Current unhealthy alcohol use and marijuana use were also consistently associated. Current status was strongly predicted by prior status (p < 0.0001; OR = 2.99-22.34) however, there were few other sequential relationships. Associations in the HIV infected and uninfected subgroups were largely the same with the following exceptions. Smoking preceded unhealthy alcohol use and current smoking was associated with current depression in the HIV infected subgroup only (p < 0.001; OR = 1.33-1.41 and p < 0.001; OR = 1.25-1.43). Opioid use and current unhealthy alcohol use were negatively associated only in the HIV negative subgroup (p = 0.01; OR = 0.75). Patterns of depression, smoking, unhealthy alcohol use, and other substance use were temporally concordant, particularly with regard to depression and substance use. These patterns may inform future development of more integrated screening and treatment strategies.

Background Alcohol and marijuana are the two most abused substances in US colleges. However, research on the combined influence (cross sectional or longitudinal) of these substances on academic performance is currently scant. Methods Data were derived from the longitudinal 2-year Brain and Alcohol Research in College Students (BARCS) study including 1142 freshman students who completed monthly marijuana use and alcohol consumption surveys. Subjects were classified into data-driven groups based on their alcohol and marijuana consumption. A linear mixed-model (LMM) was employed using this grouping factor to predict grade point average (GPA), adjusted for a variety of socio-demographic and clinical factors. Results Three data-driven clusters emerged: 1) No/low users of both, 2) medium-high alcohol/no-low marijuana, and 3) medium-high users of both substances. Individual cluster derivations between consecutive semesters remained stable. No significant interaction between clusters and semester (time) was noted. Post-hoc analysis suggest that at the outset, compared to sober peers, students using moderate to high levels of alcohol and low marijuana demonstrate lower GPAs, but this difference becomes non-significant over time. In contrast, students consuming both substances at moderate-to-high levels score significantly lower at both the outset and across the 2-year investigation period. Our follow-up analysis also indicate that when students curtailed their substance use over time they had significantly higher academic GPA compared to those who remained stable in their substance use patterns over the two year period. Conclusions Overall, our study validates and extends the current literature by providing important implications of concurrent alcohol and marijuana use on academic achievement in college.

Homelessness and substance use often coexist, resulting in high morbidity. Emergency department (ED) patients have disproportionate rates of both homelessness and substance use, yet little research has examined the overlap of these issues in the ED setting. We aimed to characterize alcohol and drug use in a sample of homeless vs. non-homeless ED patients. A random sample of urban hospital ED patients were invited to complete an interview regarding housing, substance use, and other health and social factors. We compared substance use characteristics among patients who did vs. did not report current literal (streets/shelter) homelessness. Additional analyses were performed using a broader definition of homelessness in the past 12-months. Patients who were currently homeless (n = 316, 13.7%) versus non-homeless (n = 1,993, 86.3%) had higher rates of past year unhealthy alcohol use (44.4% vs. 30.5%, p < .0001), any drug use (40.8% vs. 18.8%, p < .0001), heroin use (16.7% vs. 3.8%, p < .0001), prescription opioid use (12.5% vs. 4.4%, p < .0001), and lifetime opioid overdose (15.8% vs. 3.7%, p < .0001). In multivariable analyses, current homelessness remained significantly associated with unhealthy alcohol use, AUDIT scores among unhealthy alcohol users, any drug use, heroin use, and opioid overdose; past 12-month homelessness was additionally associated with DAST-10 scores among drug users and prescription opioid use. Patients experiencing homelessness have higher rates and greater severity of alcohol and drug use than other ED patients across a range of measures. These findings have implications for planning services for patients with concurrent substance use and housing problems. Copyright © 2018 Elsevier B.V. All rights reserved.

Individual differences in drug dependence may be mediated by several abnormalities in associative learning, including perseveration of drug-seeking following contingency change, greater control over drug-seeking by Pavlovian stimuli, or greater sensitivity to drug reinforcement establishing higher rates of drug-seeking. To evaluate these three candidate markers for nicotine dependence, Experiment 1 contrasted daily (N = 22) and nondaily smoker groups (N = 22) on a novel instrumental learning task, where one S+ was first trained as a predictor of tobacco reward before being extinguished. Experiment 2 compared daily (N = 18) and nondaily smoker groups (N = 18) on a concurrent-choice task for tobacco and chocolate reward before an extinction test in which the tobacco response was extinguished, followed by a Pavlovian-to-instrumental transfer test, wherein the impact of tobacco and chocolate cues on concurrent choice was measured (gender was balanced within each smoker group). The results showed no group difference in sensitivity to extinction of either the stimulus-drug or response-drug contingency in Experiments 1 and 2, respectively, nor did groups show a difference in Pavlovian-to-instrumental transfer of control over tobacco choice. By contrast, nicotine-dependence status was marked by a higher frequency of tobacco choice in the concurrent-choice procedure, and this choice preference was associated with subjective craving (gender did not affect any behavioral measure). These results favor the view that nicotine dependence in this sample is not determined by individual predilection for perseveration or stimulus-control over drug-seeking, but by greater sensitivity to reinforcement of instrumental drug choice. Value-based decision theories of dependence are discussed.

Little is known about the association of various psychiatric disorders with the risk of developing dependence or abuse among users of various psychoactive substances (conditional dependence, CD; conditional abuse, CA). Evaluate the association of psychiatric disorders with CA only, CD only and CA+CD. Secondary analysis of data from 43,093 non-institutionalized US adults in the first wave (2001-2002) of the National Epidemiological Survey on Alcohol and Related Conditions. A structured diagnostic interview allowed classification by lifetime psychiatric diagnosis (DSM-IV criteria) and psychoactive substance use. Data were analyzed using weighted proportions, 95% CIs, and weighted logistic regression models to generate odds ratios (OR) adjusted for socio-demographic characteristics. Psychiatric disorders were associated with higher prevalence of psychoactive substance use, regardless of type of disorder or substance. CA, CD and CA+CD prevalence rates were generally higher than unconditional prevalence rates among respondents with and without psychiatric disorders. Respondents with multiple disorders (mainly mood and anxiety disorders) had higher rates of CA+CD on most, but not all, psychoactive substances (e.g., not heroin), while schizophrenia was associated only with higher rates of tranquilizer CA+CD. Psychiatric disorders had few associations with CA only and CD only on psychoactive substances. Study findings suggest that mood and anxiety disorders are associated with increased prevalence of substance use and increased transition from use to CA and CD, while schizophrenia is associated with increased transition from abstinence to use, especially for marijuana.

Background Little is known about the association of various psychiatric disorders with the risk of developing dependence or abuse among users of various psychoactive substances (conditional dependence, CD; conditional abuse, CA). Objectives Evaluate the association of psychiatric disorders with CA only, CD only and CA +CD. Method Secondary analysis of data from 43,093 non-institutionalized US adults in the first wave (2001–2002) of the National Epidemiological Survey on Alcohol and Related Conditions. A structured diagnostic interview allowed classification by lifetime psychiatric diagnosis (DSM-IV criteria) and psychoactive substance use. Data were analyzed using weighted proportions, 95% CIs, and weighted logistic regression models to generate odds ratios (OR) adjusted for socio-demographic characteristics. Results Psychiatric disorders were associated with higher prevalence of psychoactive substance use, regardless of type of disorder or substance. CA, CD and CA+ CD prevalence rates were generally higher than unconditional prevalence rates among respondents with and without psychiatric disorders. Respondents with multiple disorders (mainly mood and anxiety disorders) had higher rates of CA+CD on most, but not all, psychoactive substances (e.g., not heroin), while schizophrenia was associated only with higher rates of tranquilizer CA+ CD. Psychiatric disorders had few associations with CA only and CD only on psychoactive substances. Conclusion Study findings suggest that mood and anxiety disorders are associated with increased prevalence of substance use and increased transition from use to CA and CD, while schizophrenia is associated with increased transition from abstinence to use, especially for marijuana. Findings did not support the self-medication hypothesis of substance use disorders. PMID:21641123

Alcohol use disorders, substance use disorders, and antisocial personality disorder share a common externalizing liability, which may also include attention-deficit hyperactivity disorder (ADHD). However, few studies have compared formal quantitative models of externalizing liability, with the aim of delineating the categorical and/or continuous nature of this liability in the community. This study compares categorical, continuous, and hybrid models of externalizing liability. Data were derived from the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653). Seven disorders were modeled: childhood ADHD and lifetime diagnoses of antisocial personality disorder (ASPD), nicotine dependence, alcohol dependence, marijuana dependence, cocaine dependence, and other substance dependence. The continuous latent trait model provided the best fit to the data. Measurement invariance analyses supported the fit of the model across genders, with females displaying a significantly lower probability of experiencing externalizing disorders. Cocaine dependence, marijuana dependence, other substance dependence, alcohol dependence, ASPD, nicotine dependence, and ADHD provided the greatest information, respectively, about the underlying externalizing continuum. Liability to externalizing disorders is continuous and dimensional in severity. The findings have important implications for the organizational structure of externalizing psychopathology in psychiatric nomenclatures.

The Case for Chronic Disease Management for Addiction
Saitz, Richard; Larson, Mary Jo; LaBelle, Colleen; Richardson, Jessica; Samet, Jeffrey H.
2009-01-01
Chronic disease (care) management (CDM) is a patient-centered model of care that involves longitudinal care delivery; integrated, and coordinated primary medical and specialty care; patient and clinician education; explicit evidence-based care plans; and expert care availability. The model, incorporating mental health and specialty addiction care, holds promise for improving care for patients with substance dependence who often receive no care or fragmented ineffective care. We describe a CDM model for substance dependence and discuss a conceptual framework, the extensive current evidence for component elements, and a promising strategy to reorganize primary and specialty health care to facilitate access for people with substance dependence. The CDM model goes beyond integrated case management by a professional, colocation of services, and integrated medical and addiction care—elements that individually can improve outcomes. Supporting evidence is presented that: 1) substance dependence is a chronic disease requiring longitudinal care, although most patients with addictions receive no treatment (eg, detoxification only) or short-term interventions, and 2) for other chronic diseases requiring longitudinal care (eg, diabetes, congestive heart failure), CDM has been proven effective.

Background. There are limited community based treatment services for drug dependence in India. Rural areas and urban resettlement colonies are in particular deficient in such services. Aims. The current study aimed at preliminary assessment of substance use disorder management services at a community based substance use treatment clinic in an urban resettlement colony. Methods. The study was carried out at community based substance use treatment centre in a resettlement colony in India. The records of the centre were chart reviewed. Results. A total of 754 patients were registered at the clinic during the study period. Heroin was the primary drug of abuse for 63% of the patients. The mean duration of follow-up for the patients with opioid and alcohol dependence was 13.47 (SD ± 10.37; range 0-39) months. A total of 220 patients of opioid dependence were prescribed substation or abstinence directed therapy. Buprenorphine (87), slow release oral morphine (SROM) (16), and dextropropoxyphene (98) were used for opioid substitution. Conclusion. It is possible to deliver substance use disorder treatment services in community setting. There is a need to develop area specific community based treatment services for substance abuse in socially disadvantaged populations such as urban resettlement colonies.

Acute myeloid leukemia progressed from myelodysplastic syndrome (MDS/AML) is generally incurable with poor prognosis for complex karyotype including monosomy 7 (-7). Qinghuang Powder (, QHP), which includes Qing Dai (Indigo naturalis) and Xiong Huang (realgar) in the formula, is effective in treating MDS or MDS/AML even with the unfavorable karyotype, and its therapeutic efficacy could be enhanced by increasing the Xiong huang content in the formula, while Xiong huang contains > 90% arsenic disulfide (As2S2). F-36p cell line was established from a MDS/AML patient with complex karyotype including -7, and was in cytokine-dependent. The present study was to investigate the effects of As2S2 on F-36p cells. Cell proliferation was measured by an 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Cell apoptosis was identified by Annexin V-staining. Cell viability was determined by a propidium iodide (PI) exclusion. Erythroid differentiation was evaluated by the expression of cell surface antigen CD235a (GpA). After treatment with As2S2 at concentrations of 0.5 to 16 μmol/L for 72 h, As2S2 inhibited the proliferation of F-36p cells. The 50% inhibitory concentrations (IC50) of As2S2 against the proliferation of F-36p cells was 6 μmol/L. The apoptotic cells significantly increased in a dose-dependent mannar (P<0.05). The cell viabilities were significantly inhibited by As2S2 dose-dependent in a dose-dependent manner (P<0.05). Significant increases of CD235a-positive cells were concurrently observed (P<0.05) also in a dose-dependent manner. As2S2 could inhibit proliferation and viability, induce apoptosis, and concurrently promote erythroid differentiation dose-dependently in F-36p cells. As2S2 can inhibit proliferation and viability, induce apoptosis, and concurrently promote erythroid differentiation in cytokine-dependent MDS-progressed human leukemia cell line F-36p with complex karyotype including -7. The data suggest that QHP and/or As2S2 could be a potential candidate in the treatment of MDS or MDS/AML even with unfavorable cytogenetics.

Individuals' decision processes play a central role in understanding modern migration phenomena and other demographic processes. Their integration into agent-based computational demography depends largely on suitable support by a modelling language. We are developing the Modelling Language for Linked Lives (ML3) to describe the diverse decision processes of linked lives succinctly in continuous time. The context of individuals is modelled by networks the individual is part of, such as family ties and other social networks. Central concepts, such as behaviour conditional on agent attributes, age-dependent behaviour, and stochastic waiting times, are tightly integrated in the language. Thereby, alternative decisions are modelled by concurrent processes that compete by stochastic race. Using a migration model, we demonstrate how this allows for compact description of complex decisions, here based on the Theory of Planned Behaviour. We describe the challenges for the simulation algorithm posed by stochastic race between multiple concurrent complex decisions.

Prior studies attempted to explore the association between schizophrenia and hepatitis C virus (HCV). However, their conclusions were inconsistent. This study aimed to examine the association of schizophrenia with HCV using a population-based dataset in Taiwan. There were 6097 patients with schizophrenia and 6097 sex- and age-matched comparison patients without schizophrenia included in this study. We defined the dependent variable of interest as whether or not a patient had received a diagnosis of HCV. We found that of the sampled patients, 2.1% of patients with schizophrenia and 1.4% of comparison patients had concurrent HCV. We further found that schizophrenia was not significantly associated with concurrent HCV after adjusting for sex, age, urbanization level, geographic region, monthly income, and drug abuse. However, of the sampled male patients, the adjusted odds of concurrent hepatitis C for patients with schizophrenia were 1.72-times higher than the odds of concurrent HCV among comparison patients. We failed to observe this association among female sampled patients. We concluded that schizophrenia was not significantly associated with concurrent HCV. However, of the sampled male patients, the risk of concurrent HCV among patients with schizophrenia was higher than comparison patients. Copyright © 2017 Elsevier B.V. All rights reserved.

Substance abuse cessation is one of the leading factors in determining the eligibility for the heart transplantation waiting list, as noncompliance with this issue may seriously endanger posttransplantation outcomes. Yet, the prevalence of substance-related disorders among candidates for heart transplantation has not been evaluated enough. Eighty three heart transplantation candidates were assessed for prior or current substance-related disorders through the Structured Clinical Interview for mental disorders according to DSM-IV. A prior history of at least one substance-related disorder was found in 64% of patients, with nicotine dependence as the most prevalent diagnosis (61.4% of the sample). Ten subjects were currently smokers, despite heart failure. A prior history of alcohol abuse and caffeine intoxication was found in 9.6% and 2.4% of patients, respectively. Substance abuse or dependence behaviors should be monitored during all the phases of heart transplantation program. Early identification of current substance-related disorders may allow better allocation of organ resources and proper lifestyle modification programs provision. A prior history of substance-related disorders should alert physicians to assess patients for possible relapse, especially after transplantation. The inclusion of a specialist in the assessment and treatment of substance-related disorders in the heart transplantation unit may reduce the risk of unsuccessful outcomes due to noncompliance with an adequate lifestyle.
Substance use and addictive disorders in DSM-5 and ICD 10 and the draft ICD 11.
Saunders, John B
2017-07-01
The present review compares and contrasts the diagnostic entities and taxonomy of substance use and addictive disorders in the beta draft of the Eleventh Revision of the International Classification of Diseases (ICD 11), which was released in November 2016, and the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which was published in mid-2013. Recently published papers relevant to these two classification systems are examined. New initiatives in diagnosis and assessment including the addictions neuroclinical assessment are noted. The draft ICD 11 retains substance dependence as the 'master diagnosis' in contrast to the broader and heterogeneous concept of substance use disorder in DSM-5 and there is empirical support for the coherence of substance dependence for alcohol, cannabis, and prescribed opioids. Both systems now include gambling disorder in the addictive disorders section, with it being transferred from the impulse control disorders section. The new diagnosis of Internet gaming disorder is included in DSM-5 as a condition for further study, and gaming disorder is grouped with the substance and gambling disorders in the draft ICD 11. Initiatives from the U.S. National Institutes of Health (NIH) are highlighting the importance of capturing the neurobiological phases of the addictive cycle in clinical diagnosis and assessment. Although most of the changes in the draft ICD 11 and DSM-5 are incremental, the contrast between DSM-5 substance use disorder and substance dependence in the draft ICD 11, and the inclusion of gambling disorder and gaming disorder will generate much discussion and research.

Introduction As a primary point of contact within the health care system, family physicians are able to play a vital role in identifying individuals with substance use disorders and connecting them to the appropriate treatment. However, there is very little data available on whether family physicians are actively screening for and treating substance use disorders. The objective of the current survey was to assess whether family physicians in Ontario are screening for alcohol, opioid and tobacco use disorders, using validated tools and providing treatment. Methods An online survey consisting of a series of 38 primarily close-ended questions was circulated to family physicians in Ontario. Rates of screening for alcohol, opioid and tobacco dependence, use of validated tools for screening, providing treatment for dependent individuals and the current barriers to the prescription of pharmacotherapies for these drug dependences were assessed. Results The use of validated screening tools was limited for all three substances. Screening by family physicians for the substance use disorders among adolescents was much lower than screening among adults. Pharmacotherapy was more commonly used as an intervention for tobacco dependence than for alcohol and opioid dependence. This was explained by the lack of knowledge among family physicians on the pharmacotherapies for alcohol and opioid dependence. Conclusions Findings from the current study suggest there is a need for family physicians to integrate screening for substance use disorders using validated tools into their standard medical practice. Furthermore, there is a need for increased knowledge on pharmacotherapies for alcohol and opioid use disorders. It is important to note that the low response rate is a major limitation to this study. One possible reason for this low response rate may be a lack of interest and awareness among family physicians on the importance of screening and treatment of substance use disorders in Ontario.

Posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) are commonly co-occurring disorders associated with more adverse consequences than PTSD alone. Prolonged exposure therapy (PE) is one of the most efficacious treatments for PTSD. However, among individuals with PTSD-SUD, 35–62% of individuals drop out of trauma-focused exposure treatments. Thus, it is important to identify predictors of PTSD treatment dropout among substance abusers with PTSD in order to gain information about adapting treatment strategies to enhance retention and outcomes. The current study explored pre-treatment predictors of early termination from PE treatment in a sample of 85 individuals receiving concurrent treatment for PTSD and a SUD in a residential treatment facility as part of a randomized controlled trial. The results indicated that less education and more anxiety sensitivity uniquely predicted PE treatment dropout. Demographic variables, PTSD severity, SUD severity, mental health comorbidities, and emotion regulation difficulties did not predict treatment dropout. These results suggest that adding pre-treatment interventions that address anxiety sensitivity, and promote social adjustment and cognitive flexibility, could possibly improve PE retention rates in clients with high anxiety or low education.

Background Treatment engagement is often measured in terms of treatment retention and drop out, resource utilization, and missed appointments. Since persons may regularly attend treatment sessions but not pay close attention, actively participate, or comply with the program, attendance may not reflect the level of effort put into treatment. Teens in correctional settings may feel coerced to attend treatment, making it necessary to develop measures of treatment involvement beyond attendance. This study describes the development and validation of the Adolescent Substance Treatment Engagement Questionnaire (ASTEQ), Teen and Counselor versions. Methods The psychometric properties of the ASTEQ were examined in a sample of incarcerated teens (N = 205) and their counselors. Principal component analysis was conducted on teen and counselor versions of the questionnaire. Results Scales of positive and negative treatment engagement were found, reflecting both overt behaviors (joking around, talking to others) and attitudes (interest in change). Significant correlations with constructs related to treatment attitudes and behaviors, and misbehaviors (including substance use) demonstrate good concurrent and predictive validity. Teen and counselor ratings of engagement produced validity correlations in the medium effect size range. Conclusions These measures comprise a valid and reliable method for measuring treatment engagement for incarcerated teens. PMID:26021405

The prospective effects of impulsivity on alcohol and tobacco use in a college sample.
Doran, Neal; Trim, Ryan S
2013-01-01
Alcohol and tobacco use are strongly associated, particularly in younger populations, and concurrent use may encourage progression toward dependence on both substances. Impulsivity has been linked to the use of alcohol and tobacco individually, but has not been studied in terms of its association with use of both. This study tested the hypothesis that the effects of impulsivity (sensation seeking and negative urgency) on smoking initiation in a sample of college students (n = 400) would be mediated by alcohol consumption. We also predicted that sensation seeking and negative urgency would predict alcohol and cigarette use and overlap among initiators. Sensation seeking and negative urgency both predicted smoking initiation, but only the former effect was mediated by alcohol use. Among initiators, sensation seeking was associated with more frequent alcohol use as well as more frequent overlap between alcohol and tobacco use but not with smoking frequency. Higher negative urgency was associated with more frequent smoking, but not with alcohol use or alcohol/tobacco overlap. Findings are consistent with previous research in college samples and suggest the existence of multiple pathways to alcohol and tobacco use and co-use in college students.

Positive social interaction could play an essential role in switching the preference of the substance dependent individual away from drug related activities. We have previously shown that conditioned place preference (CPP) for cocaine at the dose of 15 mg/kg and CPP for four 15-min episodes of social interaction were equally strong when rats were concurrently conditioned for place preference by pairing cocaine with one compartment and social interaction with the other. The aim of the present study was to investigate the differential activation of brain regions related to the reward circuitry after acquisition/expression of cocaine CPP or social interaction CPP. Our findings indicate that cocaine CPP and social interaction CPP activated almost the same brain regions. However, the granular insular cortex and the dorsal part of the agranular insular cortex were more activated after cocaine CPP, whereas the prelimbic cortex and the core subregion of the nucleus accumbens were more activated after social interaction CPP. These results suggest that the insular cortex appears to be potently activated after drug conditioning learning while activation of the prelimbic cortex-nucleus accumbens core projection seems to be preferentially involved in the conditioning to non-drug stimuli such as social interaction.
Responses of python gastrointestinal regulatory peptides to feeding
Secor, Stephen M.; Fehsenfeld, Drew; Diamond, Jared; Adrian, Thomas E.
2001-01-01
In the Burmese python (Python molurus), the rapid up-regulation of gastrointestinal (GI) function and morphology after feeding, and subsequent down-regulation on completing digestion, are expected to be mediated by GI hormones and neuropeptides. Hence, we examined postfeeding changes in plasma and tissue concentrations of 11 GI hormones and neuropeptides in the python. Circulating levels of cholecystokinin (CCK), glucose-dependent insulinotropic peptide (GIP), glucagon, and neurotensin increase by respective factors of 25-, 6-, 6-, and 3.3-fold within 24 h after feeding. In digesting pythons, the regulatory peptides neurotensin, somatostatin, motilin, and vasoactive intestinal peptide occur largely in the stomach, GIP and glucagon in the pancreas, and CCK and substance P in the small intestine. Tissue concentrations of CCK, GIP, and neurotensin decline with feeding. Tissue distributions and molecular forms (as determined by gel-permeation chromatography) of many python GI peptides are similar or identical to those of their mammalian counterparts. The postfeeding release of GI peptides from tissues, and their concurrent rise in plasma concentrations, suggests that they play a role in regulating python-digestive responses. These large postfeeding responses, and similarities of peptide structure with mammals, make pythons an attractive model for studying GI peptides. PMID:11707600

The objective of this study was to estimate the current prevalence of psychiatric disorders in cocaine-dependent patients who attend different treatment centres in the Community of Madrid. A prospective multicentre study was used, and a total of 197 cocaine-dependent subjects were assessed. The assessment instrument used for diagnosis was the Psychiatric Research Interview for Substance and Mental Disorders (PRISM-IV). The main findings of this study were a high prevalence of psychiatric comorbidity in cocaine-dependent patients seeking treatment (64.0%). The most common Non Substance Use Disorders found were attention-deficit/hyperactivity Disorders (34.5%) and depressive disorders (13.7%). The most common Substance Use Disorder was alcohol dependence (28.4%). Cocaine-dependent patients who had a depressive disorder and were alcohol dependent presented a more severe clinical profile and a higher degree of psychopathology, measured using different assessment tools, than the patients who were only cocaine dependent. These data suggest that the presence of psychiatric comorbidity could constitute a risk factor associated with the severity of cocaine dependence. The clinical heterogeneity found also indicates the need to search for individualised treatments that more specifically fit the needs of this population.

Substance abuse worsens the course of schizophrenia, but it is not known whether or not there are differences between specific substances concerning their association with the hospitalizations of patients with schizophrenia. The primary aims of this study were to examine the possible associations between amphetamine, cannabis, and opioid abuse, and the risk of hospitalizations among patients with schizophrenia. The study population consisted of 146 patients with ICD-defined schizophrenia from two different geographical sites in Finland, and it included both inpatients and outpatients. Data were collected retrospectively from the patients' medical files. Substance abuse was defined as either harmful use or dependence according to ICD-10. The cumulative prevalence of substance abuse was 10.9% (16/146) for cannabis, 8.9% (13/146) for amphetamine, and 4.1% (6/146) for opioids. Among patients with schizophrenia and abuse of any substance, the number of hospitalizations was about 1.5-fold when compared to those without substance abuse. The incidence rate ratio for hospitalizations was 2.9 (95% CI 2.47-3.63) for opioids, 2.0 (1.71-2.41) for amphetamine, and 1.6 (1.33-1.84) for cannabis, when compared with no abuse of each substance. The risk of hospitalizations was significantly higher for opioids when compared with amphetamine (p < 0.001) or cannabis (p < 0.001). Harmful use or dependence of opioids among patients with schizophrenia is associated with significantly higher risk of hospitalizations than either harmful use or dependence of amphetamine or cannabis.

Addressing the psychological distress of individuals experiencing substance use disorders has too often been relegated to the 'too hard basket', leaving those affected with little choice but to receive treatments aimed solely at addressing their drug and alcohol issues. Conversely, individuals receiving support for psychological issues are often underdiagnosed with regards to any comorbid substance misuse problems. In fact, to date, no definitive treatment model exists that gives equal focus to the treatment of both psychological well-being and substance-related addictions. This is not to suggest, however, that existing treatment programmes for substance misuse are not impacting positively on clients' mental health, rather that further research is needed in order to determine what it is that is supporting such improvements. The aim of this study, therefore, was to address this imbalance by examining the correlation between substance dependence and psychological well-being. Using a descriptive correlation design, the Severity of Dependence and Kessler 10 scales were administered to 37 inpatient and outpatient clients at a rural drug and alcohol rehabilitation service, at intake and 2 months into treatment. Data were analysed using descriptive statistics and paired-samples t-tests. Positive correlative factors of improvement between substance dependence and psychological well-being were found for both groups. In light of these findings, the authors recommend that future research be undertaken to investigate the causal factors for this correlation. © 2016 Australian College of Mental Health Nurses Inc.

Essential limitations of the standard THz Time Domain Spectroscopy (TDS), which lead to false detection of dangerous and neutral substances in commonly used materials, are demonstrated using the physical experiment with chocolate under real conditions as well as with semiconductors under laboratory conditions. To overcome this disadvantage, we propose using the time-dependent spectrum of the THz pulse, transmitted through or reflected from a substance. For quality assessment of the standard substance absorption frequency presence in the signal under analysis, we use time-dependent integral correlation criteria. The influence of aperture placed in front of the sample on spectral properties of silicon wafers with different resistivity is demonstrated as well.
Generalized concurrence in boson sampling.

A fundamental question in linear optical quantum computing is to understand the origin of the quantum supremacy in the physical system. It is found that the multimode linear optical transition amplitudes are calculated through the permanents of transition operator matrices, which is a hard problem for classical simulations (boson sampling problem). We can understand this problem by considering a quantum measure that directly determines the runtime for computing the transition amplitudes. In this paper, we suggest a quantum measure named "Fock state concurrence sum" C S , which is the summation over all the members of "the generalized Fock state concurrence" (a measure analogous to the generalized concurrences of entanglement and coherence). By introducing generalized algorithms for computing the transition amplitudes of the Fock state boson sampling with an arbitrary number of photons per mode, we show that the minimal classical runtime for all the known algorithms directly depends on C S . Therefore, we can state that the Fock state concurrence sum C S behaves as a collective measure that controls the computational complexity of Fock state BS. We expect that our observation on the role of the Fock state concurrence in the generalized algorithm for permanents would provide a unified viewpoint to interpret the quantum computing power of linear optics.

School based efforts need to embrace a continuum of care model that moves beyond solely primary prevention to address the needs of students who are identified as substance dependent. The extent of this problem and barriers to program implementation are presented. Efforts to offer services through Student/Assistance Programs, School-based…
[Long-term problem with addictive substances dependence and its solution: a case report].

The recovery of a male health professional dependent on alcohol and other psychoactive substances was possible only after long-term cooperation with the organization Alcoholics Anonymous. This case report illustrates the principle that addiction is a chronic disease and its treatment is successful if it is treated as a chronic disease.

Despite emerging evidence for the comorbidity of posttraumatic stress disorder (PTSD) and migraine, few studies have examined the relation of PTSD and migraine, particularly among clinical populations at-risk for both conditions (e.g., substance-dependent patients). This study examined the role of PTSD symptoms in migraine and headache-related disability within a sample of 153 substance-dependent inpatients (37.25% female, Mean age 36.46). PTSD symptoms predicted both migraine and headache-related disability above and beyond gender, depression and anxiety symptoms, the experience of a Criterion A traumatic event, and current alcohol use disorder. Findings highlight the strong association between migraine and PTSD symptoms in a unique population at risk for both conditions.
[Adaptation of a peer pressure scale in French and German: the Peer Pressure Inventory].

Peer pressure is regarded as an important determinant of substance use, sexual behavior and juvenile delinquency. However, few peer pressure scales are validated, especially in French or German. Little is known about the factor structure of such scales or the kind of scale needed: some scales takes into account both peer pressure to do and peer pressure not to do, while others consider only peer pressure to do. The aim of the present study was to adapt French and German versions of the Peer Pressure Inventory, which is one of the most widely used scales in this field. We considered its factor structure and concurrent validity. Five thousand eight hundred and sixty-seven young Swiss men filled in a questionnaire on peer pressure, substance use, and other variables (conformity, involvement) in a cohort study. We identified a four-factor structure, with the three factors of the initial Peer Pressure Inventory (involvement, conformity, misconduct) and adding a new one (relationship with girls). A non-valued scale (from no peer pressure to peer pressure to do only) showed stronger psychometric qualities than a valued scale (from peer pressure not to do to peer pressure to do). Concurrent validity was also good. Each behavior or attitude was significantly associated with peer pressure. Peer pressure seems to be a multidimensional concept. In this study, peer pressure to do showed the strongest influence on participants. Indeed, peer pressure not to do did not add anything useful. Only peer pressure to do affected young Swiss men's behaviors and attitudes and was reliable. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Isocyanates are used in polyurethane production. Dermal exposure to isocyanates can induce contact allergy. The most common isocyanate is diphenylmethane diisocyanate used for industrial purposes. The isomer diphenylmethane-4,4'-diisocyanate (4,4'-MDI) is used in patch testing. Diphenylmethane-4,4'-diamine (4,4'-MDA) is its corresponding amine. Concurrent reactions to 4,4'-MDI and 4,4'-MDA have been reported, as have concurrent reactions to 4,4'-MDI and dicyclohexylmethane-4,4'-diisocyanate (4,4'-DMDI). To investigate the sensitization capacities and the cross-reactivity of 4,4'-MDI, 4,4'-MDA, 4,4'-DMDI, and dicyclohexylmethane-4,4'-diamine (4,4'-DMDA). The guinea-pig maximization test (GPMT) was used. The GPMT showed sensitizing capacities for all investigated substances: 4,4'-MDI, 4,4'-MDA, 4,4'-DMDI, and 4,4'-DMDA (all p < 0.001). 4,4'-MDI-sensitized animals showed cross-reactivity to 4,4'-MDA (p < 0.001) and 4,4'-DMDI (all p < 0.05). 4,4'-MDA-sensitized animals showed cross-reactivity to 4,4'-DMDA (p = 0.008). All of the investigated substances were shown to be strong sensitizers. Animals sensitized to 4,4'-MDI showed cross-reactivity to 4,4'-MDA and 4,4'-DMDI, supporting previous findings in the literature. The aromatic amine 4,4'-MDA showed cross-reactivity to the aliphatic amine 4,4'-DMDA. © 2017 The Authors. Contact Dermatitis published by John Wiley & Sons Ltd.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are known to be at significantly greater risk for the development of substance use disorders (SUD) compared to peers. Impulsivity, which could lead to higher levels of drug use, is a known symptom of ADHD and likely accounts, in part, for this relationship. Other factors, such as a biologically increased susceptibility to substance dependence (addiction), may also play a role. This report further examines the relationships between childhood ADHD, adolescent- onset SUD, and substance abuse and substance dependence in adulthood. Individuals with childhood ADHD and non-ADHD controls from the same population-based birth cohort were invited to participate in a prospective outcome study. Participants completed a structured neuropsychiatric interview with modules for SUD and a psychosocial questionnaire. Information on adolescent SUD was obtained retrospectively, in a previous study, from medical and school records. Associations were summarized using odds ratios (OR) and 95% CIs estimated from logistic regression models adjusted for age and gender. A total of 232 ADHD cases and 335 non-ADHD controls participated (mean age, 27.0 and 28.6 years, respectively). ADHD cases were more likely than controls to have a SUD diagnosed in adolescence and were more likely to have alcohol (adjusted OR 14.38, 95% CI 1.49-138.88) and drug (adjusted OR 3.48, 95% CI 1.38-8.79) dependence in adulthood. The subgroup of participating ADHD cases who did not have SUD during adolescence were no more likely than controls to develop new onset alcohol dependence as adults, although they were significantly more likely to develop new onset drug dependence. Our study found preliminary evidence that adults with childhood ADHD are more susceptible than peers to developing drug dependence, a disorder associated with neurological changes in the brain. The relationship between ADHD and alcohol dependence appears to be more complex.

Recently, the NIH called for additional research on the topic of viral and host factors contributing to impaired cognitive and neural function in HIV/AIDS patients and their response to antiretroviral treatment. This investigation responds to that call by examining a host factor, a family history of substance dependence, often overlooked in cognitive and neuroimaging studies of HIV/AIDS. We categorized 146 HIV-1 seropositive patients receiving antiretroviral treatment (ART) and 92 seronegative volunteers by the presence or absence of alcohol, cocaine, or heroin dependence affecting a biological parent. Seropositive patients were further categorized by the estimated ability of their individual ART regimens to penetrate the CNS. The indicator of brain function was a 3-7Hz oscillatory electroencephalographic response (theta ERO) evoked by target stimuli presented during a simple selective attention task. The analysis revealed that the presence of a family history of substance dependence obscured the reduction in frontal theta ERO power accompanying the presence of HIV-1 as well as the improvement in frontal theta ERO power accompanying treatment with ART agents estimated to have greater (n=41) versus lesser (n=105) CNS penetrance. Secondary analyses employing sLORETA source localization techniques revealed that the source of the theta ERO response was similarly reduced by the presence of either HIV-1 or a family history of substance dependence. We conclude that a family history of substance dependence complicates and obscures the subtle neurophysiological changes which typically accompany HIV/AIDS and ART. Studies of new therapeutic agents for HIV-1-associated cognitive and neurophysiological impairments must consider this complication and exclude or control it. Copyright © 2012 Elsevier Ireland Ltd.

Abstract Introduction: Smoking is highly prevalent in substance dependence, but smoking-cessation treatment (SCT) is more challenging in this population. To increase the success of smoking cessation services, it is important to understand potential therapeutic targets like nicotine craving that have meaningful but highly variable relationships with smoking outcomes. This study characterized the presence, magnitude, and specificity of nicotine craving as a mediator of the relationship between SCT and smoking abstinence in the context of stimulant-dependence treatment. Methods: This study was a secondary analysis of a randomized, 10-week trial conducted at 12 outpatient SUD treatment programs. Adults with cocaine and/or methamphetamine dependence ( N = 538) were randomized to SUD treatment as usual (TAU) or TAU+SCT. Participants reported nicotine craving, nicotine withdrawal symptoms, and substance use in the week following a uniform quit attempt of the TAU+SCT group, and self-reported smoking 7-day point prevalence abstinence (verified by carbon monoxide) at end-of-treatment. Results: Bootstrapped regression models indicated that, as expected, nicotine craving following a quit attempt mediated the relationship between SCT and end-of-treatment smoking point prevalence abstinence (mediation effect = 0.09, 95% CI = 0.04% to 0.14%, P < .05, 14% of total effect). Nicotine withdrawal symptoms and substance use were not significant mediators ( P s > .05, <1% of total effect). This pattern held for separate examinations of cocaine and methamphetamine dependence. Conclusions: Nicotine craving accounts for a small but meaningful portion of the relationship between smoking-cessation treatment and smoking abstinence during SUD treatment. Nicotine craving following a quit attempt may be a useful therapeutic target for increasing the effectiveness of smoking-cessation treatment in substance dependence. PMID:26048168
Absorption-emission optrode and methods of use thereof
Hirschfeld, T.B.
1990-05-29
A method and apparatus are described for monitoring the physical and chemical properties of a sample fluid by measuring an optical signal generated by a fluorescent substance and modulated by an absorber substance. The emission band of the fluorescent substance overlaps the absorption band of the absorber substance, and the degree of overlap is dependent on the physical and chemical properties of the sample fluid. The fluorescent substance and absorber substance are immobilized on a substrate so that an effective number of molecules thereof are sufficiently close for resonant energy transfer to occur, thereby providing highly efficient modulation of the fluorescent emissions of the fluorescent substance by the absorber substance. 4 figs.
Brain activation to cocaine cues and motivation/treatment status.

Motivation to change is believed to be a key factor in therapeutic success in substance use disorders; however, the neurobiological mechanisms through which motivation to change impacts decreased substance use remain unclear. Existing research is conflicting, with some investigations supporting decreased and others reporting increased frontal activation to drug cues in individuals seeking treatment for substance use disorders. The present study investigated the relationship between motivation to change cocaine use and cue-elicited brain activity in cocaine-dependent individuals using two conceptualizations of 'motivation to change': (1) current treatment status (i.e. currently receiving versus not receiving outpatient treatment for cocaine dependence) and (2) self-reported motivation to change substance use, using the Stages of Change Readiness and Treatment Eagerness Scale. Thirty-eight cocaine-dependent individuals (14 currently in treatment) completed a diagnostic assessment and an fMRI cocaine cue-reactivity task. Whole-brain analyses demonstrated that both treatment-seeking and motivated participants had lower activation to cocaine cues in a wide variety of brain regions in the frontal, occipital, temporal and cingulate cortices relative to non-treatment-seeking and less motivated participants. Future research is needed to explain the mechanism by which treatment and/or motivation impacts neural cue reactivity, as such work could potentially aid in the development of more effective therapeutic techniques for substance-dependent patients. © 2012 The Authors, Addiction Biology © 2012 Society for the Study of Addiction.

Research into the cerebral patterns that govern the formation and development of addictive behavior is one of the most interesting goals of neurophysiology. Authors of contemporary papers on the matter define a number of symptoms that are all part of substance or non-substance dependence, each one of them leading to abnormalities in the corresponding system of the brain. During the last twenty years the functional magnetic resonance imaging (fMR1) technology has been instrumental in locating such abnormalities, identifying specific parts of the brain that, when dysfunctional, may enhance addiction and cause its positive or negative symptoms. This article reviews fMRI studies aimed toward locating areas in the brain that are responsible for cognitive, emotional, and motivational dysfunction. Cerebral correlatives of impulsiveness, behavior control, and drug cravings are reviewed separately. The article also contains an overview of possibilities to further investigate the Selves of those dependent on substances, identify previously unknown diagnostic markers of substance dependence, and evaluate the effectiveness of therapy. The research under review in this article provides data that points to a special role of the nucleus caudatus as well as the nucleus accumbens, the thalamus, the insular cortex (IC), the anterior cingulate, prefrontal and orbitofrontal areas in psychological disorders that are part of substance dependence. General findings of the article are in accordance with contemporary models of addictive pattern.

Mediating the distal crime-drug relationship with proximal reactive criminal thinking.
Walters, Glenn D
2016-02-01
This article describes the results of a study designed to test whether reactive criminal thinking (RCT) does a better job of mediating the crime → drug relationship than it does mediating the drug → crime relationship after the direct effects of crime on drug use/dependency and of drug use/dependency on crime have been rendered nonsignificant by control variables. All 1,170 male members of the Pathways to Desistance study (Mulvey, 2012) served as participants in the current investigation. As predicted, the total (unmediated) effects of crime on substance use/dependence and of substance use/dependence on crime were nonsignificant when key demographic and third variables were controlled, although the indirect (RCT-mediated) effect of crime on drug use was significant. Proactive criminal thinking (PCT), by comparison, failed to mediate either relationship. The RCT continued to mediate the crime → drug relationship and the PCT continued to not mediate either relationship when more specific forms of offending (aggressive, income) and substance use/dependence (drug use, substance-use dependency symptoms) were analyzed. This offers preliminary support for the notion that even when the total crime-drug effect is nonsignificant the indirect path from crime to reactive criminal thinking to drugs can still be significant. Based on these results, it is concluded that mediation by proximal reactive criminal thinking is a mechanism by which distal measures of crime and drug use/dependence are connected.

To evaluate retrospectively the comorbidity of mental and addictive disorders in community mental health and substance misuse services in Madrid. The medical records of 400 patients from mental health and substance misuse services in Madrid were evaluated. Records were examined for the last 20 patients from each service unit. Dual pathology was constituted when a current diagnosis of mental and addictive disorders, excluding nicotine addiction, appeared on the patient's records. Prevalence of dual pathology was 34%. There were differences in the prevalence figures for the two kinds of service: 36.78% in substance misuse services, and 28.78% in mental health services. There was an association of dual diagnosis with alcohol or cocaine dependence, but not with opioid dependence. The mental disorders more prevalent in dually diagnosed than in non-dually diagnosed patients were mood disorders, personality disorders, and schizophrenia. There is a high prevalence of dual pathology in those seeking treatment, being higher in substance misuse services than in mental health services, and higher in patients with alcohol or cocaine dependence. These findings could be of help in the planning of care resource policies for these patients.

Homeless, substance-dependent men who have sex with men (MSM) continue to suffer health disparities, including high rates of HIV. One-hundred and thirty one homeless, substance-dependent MSM were randomized into a contingency management (CM) intervention to increase substance abstinence and health-promoting behaviors. Participants were recruited from a community-based, health education/risk reduction HIV prevention program and the research activities were also conducted at the community site. Secondary analyses were conducted to identify and characterize treatment responders (defined as participants in a contingency management intervention who scored at or above the median on three primary outcomes). Treatment responders were more likely to be Caucasian/White (p < .05), report fewer years of lifetime methamphetamine, cocaine, and polysubstance use (p < or = .05), and report more recent sexual partners and high-risk sexual behaviors than nonresponders (p < .05). The application of evidence-based interventions continues to be a public health priority, especially in the effort to implement effective interventions for use in community settings. The identification of both treatment responders and nonresponders is important for intervention development tailored to specific populations, both in service programs and research studies, to optimize outcomes among highly impacted populations.
Nicotine as a Factor in Stress Responsiveness Among Detoxified Alcoholics

2011-01-01
Aims: The effect of transdermal nicotine on stress reactivity was investigated in currently smoking, detoxified, substance-dependent individuals (65% alcohol dependent, n = 51; 31 male) following a psychosocial stressor. Methods: Using a randomized, double-blind, placebo-controlled design, subjects were assigned to receive either active transdermal nicotine (low or high dose) or placebo. Six hours following nicotine administration, subjects performed a laboratory psychosocial stressor consisting of two 4-min public-speaking sessions. Results: Consistent with prior reports, substance-dependent individuals displayed a blunted stress response. However, a review of the cortisol distribution data encouraged additional analyses. Notably, a significant minority of the substance-dependent individuals (33%) demonstrated elevated poststress cortisol levels. This group of responders was more likely to be alcohol dependent and to have received the high dose of nicotine [χ2(2) = 32, P < 0.0001], [χ2(2) = 18.66, P < 0.0001]. Differences in salivary cortisol responses between responders and nonresponders could not be accounted for by the length of sobriety, nicotine withdrawal levels, anxiety or depressive symptomatology at the time of the psychosocial stressor. Conclusion: These results suggest that nicotine administration may support a normalization of the salivary cortisol response following psychosocial stress in subgroups of substance-dependent individuals, particularly those who are alcohol dependent. Given the association between blunted cortisol levels and relapse, and the complex actions of nicotine at central and peripheral sites, these findings support the systematic study of factors including nicotine, which may influence stress reactivity and the recovery process in alcohol-dependent individuals.

Substance P and bradykinin, endothelium-dependent vasodilators of pig coronary artery, trigger in endothelial cells a rise in cytosolic Ca2+ concentration ([Ca2+]i) and membrane hyperpolarization. The aim of the present study was to determine the type of Ca2+-dependent K+ (KCa) currents underlying the endothelial cell hyperpolarization. The substance P-induced increase in [Ca2+]i was 30 % smaller than that induced by bradykinin, although the two peptides triggered a membrane hyperpolarization of the same amplitude. The two agonists evoked a large outward K+ current of the same conductance at maximal stimulation. Agonists applied together produced the same maximal current amplitude as either one applied alone. Iberiotoxin (50 nM) reduced by about 40 % the K+ current activated by bradykinin without modifying the substance P response. Conversely, apamin (1 μm) inhibited the substance P-induced K+ current by about 65 %, without affecting the bradykinin response. Similar results were obtained on peptide-induced membrane hyperpolarization. Bradykinin-induced, but not substance P-induced, endothelium-dependent relaxation resistant to NG-nitro-L-arginine and indomethacin was partly inhibited by 3 μm 17-octadecynoic acid (17-ODYA), an inhibitor of cytochrome P450 epoxygenase. Similarly, the bradykinin-induced K+ current was reduced by 17-ODYA. Our results show that responses to substance P and bradykinin result in a hyperpolarization due to activation of different KCa currents. A current consistent with the activation of large conductance (BKCa) channels was activated only by bradykinin, whereas a current consistent with the activation of small conductance (SKCa) channels was stimulated only by substance P. The observation that a similar electrical response is produced by different pools of channels implies distinct intracellular pathways leading to KCa current activation. PMID:10457055
A classification of substance-dependent men on temperament and severity variables.
Henderson, Melinda J; Galen, Luke W
2003-06-01
This study examined the validity of classifying substance abusers based on temperament and dependence severity, and expanded the scope of typology differences to proximal determinants of use (e.g., expectancies, motives). Patients were interviewed about substance use, depression, and family history of alcohol and drug abuse. Self-report instruments measuring temperament, expectancies, and motives were completed. Participants were 147 male veterans admitted to inpatient substance abuse treatment at a U.S. Department of Veterans Affairs medical center. Cluster analysis identified four types of users with two high substance problem severity and two low substance problem severity groups. Two, high problem severity, early onset groups differed only on the cluster variable of negative affectivity (NA), but showed differences on antisocial personality characteristics, hypochondriasis, and coping motives for alcohol. The two low problem severity groups were distinguished by age of onset and positive affectivity (PA). The late onset, low PA group had a higher incidence of depression, a greater tendency to use substances in solitary contexts, and lower enhancement motives for alcohol compared to the early onset, high PA cluster. The four-cluster solution yielded more distinctions on external criteria than the two-cluster solution. Such temperament variation within both high and low severity substance abusers may be important for treatment planning.

To synthesize the substance-dependence researches focusing on rehab treatment phase. Several criteria were used to select studies for meta analysis. Firstly, the research must have focused on the rehab period on the substance-dependence treatment, secondly, only quantitative researches that used statistics to calculate effect sizes were selected, and thirdly, all researches were from Thai libraries and were done during 1997-2006. The instrument used for data collection was comprised of two sets. The first used to collect the general information of studies including the crucial statistics and test statistics. The second was used to assess the quality of studies. Results from synthesizing 32 separate studies found that 323 effect sizes were computed in terms of the correlation coefficient "r". The psychology approach rehab program was higher in effect size than the network approach (p < 0.05). Additionally, Quasi-experimental studies were higher in effect size than correlation studies (p < 0.05). Among the quasi-experimental studies it was found that TCs revealed the highest effect size (r = 0.76). Among the correlation studies, it was found that the motivation program revealed the highest effect size (r = 0.84). The substance-use rehab treatment programs in Thailand which revealed the high effect size should be adjusted to the current program. However, the narcotic studies which focus on the rehab phase should be synthesized every 5-10 years in order to integrate new concept into the development of future the substance-dependence rehab treatment program, especially those at the research unit of the Drug Dependence Treatment Institute/Centers in Thailand.

Anxiety disorders and externalizing problems are both associated with substance use disorders. However, the nature of this relationship remains unclear. To examine whether presence of an anxiety disorder changes the association between externalizing problems (conduct disorder, oppositional defiant disorder, and attention deficit hyperactivity disorder) and substance use disorders, we analyzed data from the National Comorbidity Survey-Replication, which is based on a nationally representative sample of 9282 English-speaking adults. Presence of externalizing problems was associated with an increased odds for alcohol abuse (OR: 6.7, CI: 5.6-8.1), alcohol dependence (OR: 7.6, CI: 5.9-9.6), substance abuse (OR: 9.9, CI: 8.1-12.2), and substance dependence (OR: 13.1, CI: 9.6-17.8). Similarly, anxiety disorders were associated with increased odds for substance use disorders. The highest association was found between post-traumatic stress disorder and substance use disorder (OR: 9.2, CI: 5.4-15.5). Individuals who met diagnostic criteria for an anxiety disorder and externalizing problems showed consistently and significantly lower odds for substance use problems than subjects with externalizing problems without a comorbid anxiety disorder. The results suggest that presence of any anxiety disorder reduces the association between externalizing problems and substance use disorders, possibly because the fear of bodily symptoms prevents individuals with externalizing problems from engaging in drug-seeking behaviors.
Racial differences in treatment effect among men in a substance abuse and domestic violence program.
Scott, Melanie C; Easton, Caroline J
2010-11-01
It is unclear whether racial differences in treatment effect exist for individuals in substance abuse and domestic violence programs. This study examined racial differences in treatment effect among substance dependent Caucasian and African-American male intimate partner violence (IPV) offenders court mandated to an integrated substance abuse and domestic violence treatment. From baseline to completion of treatment (week 12), 75 participants (39 Caucasian; 36 African-American) were assessed on demographics, substance use, legal characteristics, and use of violence (physical, verbal, and psychological). African-American men served more months incarcerated in their life than Caucasian men. Both groups showed decreases in their use of physical violence and alcohol abuse over treatment. Caucasian men also showed a decrease in their use of verbal abuse. At treatment completion, both groups showed a reduction in physical abuse and alcohol abuse. Caucasian men showed a reduction in their use of verbal abuse, but African-American men did not. Substance dependent African-American male IPV offenders may benefit from interventions that thoroughly target communication skills in addition to issues of substance abuse and IPV to reduce use of verbal abuse and improve treatment outcomes among African American men.

Background Recent research has begun to examine the early maladaptive schemas of substance abusers, as it is believed that targeting these core beliefs in treatment may result in improved substance use outcomes. One special population that has received scant attention in the research literature, despite high levels of substance use, is airline pilots. Aims The current study examined the early maladaptive schemas of a sample of airline pilots (n = 64) who were seeking residential treatment for alcohol dependence and whether they differed in early maladaptive schemas from non-pilot substance abusers who were also seeking residential treatment for alcohol dependence (n = 45). Method Pre-existing medical records from patients of a residential substance abuse treatment facility were reviewed for the current study. Results Of the 18 early maladaptive schemas, results demonstrated that pilots scored higher than non-pilots on the early maladaptive schema of unrelenting standards (high internalized standards of behavior), whereas non-pilots scored higher on insufficient self-control (low frustration tolerance and self-control). Conclusions Early maladaptive schemas may be a relevant treatment target for substance abuse treatment seeking pilots and non-pilots. PMID:24701252

Exercise may be a useful treatment for substance use disorders. Participants (N=24) included treatment-seeking individuals with concurrent cocaine and tobacco-use disorder (cigarette smokers). Participants were randomized to either running or walking (30 min per session, 3 times per week) or sitting (control condition) for 4 consecutive weeks. Several metrics indicated significant differences among runners, walkers, and sitters during sessions, including mean distance covered and calories burned. In addition, remote physiological monitoring showed that the groups differed significantly according to mean maximum heart rate (HR), respiration, and locomotor activity. Across the 4-week study, exercise improved fitness measures including significantly decreasing resting HR. Though not statistically significant, exercise improved abstinence from cocaine and increased self-reports of no cocaine use in last 24h. In general, reductions in tobacco use and craving were not as robust. To our knowledge, this is the first study to evaluate the effects of a multi-week exercise program in individuals with concurrent cocaine and tobacco-use disorder. The data clearly show significant improvements in basic fitness measures and several indices reveal that exercise improved both self-report and biochemically verified reports of cocaine abstinence. Taken together, the data from this study provides preliminary evidence for the efficacy of exercise for improving fitness and reducing cocaine use. PMID:27541349

Low efficiency of the standard THz TDS method of the detection and identification of substances based on a comparison of the spectrum for the signal under investigation with a standard signal spectrum is demonstrated using the physical experiments conducted under real conditions with a thick paper bag as well as with Si-based semiconductors under laboratory conditions. In fact, standard THz spectroscopy leads to false detection of hazardous substances in neutral samples, which do not contain them. This disadvantage of the THz TDS method can be overcome by using time-dependent THz pulse spectrum analysis. For a quality assessment of the standard substance spectral features presence in the signal under analysis, one may use time-dependent integral correlation criteria. PMID:27070617

Between 5% and 30% of children in high-income countries live with a substance misusing parent, the majority of which is below dependent levels. However, little is understood about the impact of nondependent parental substance misuse upon children. We searched the international literature using rigorous systematic methods to identify studies examining parental substance misuse and adverse outcomes in children. The inclusion criteria were cross-sectional, longitudinal, case-control, and cohort studies; of children aged 0-18 years whose parents are high-risk substance misusers; reporting on their health, psychological, substance use, educational, and social outcomes. We identified 36 papers (from 33 unique studies), most of which were assessed as being of medium to high methodological quality ( N= 28). Parental nondependent substance misuse was found to be associated with adversity in children, with strong evidence of an association with externalizing difficulties ( N = 7 papers, all finding an association) and substance use ( N = 23 papers, all finding an association) in adolescents and some evidence of adverse health outcomes in early childhood ( N = 6/8 papers finding an association). There is less evidence of an association between parental substance misuse and adverse educational and social outcomes. The body of evidence was largest for parental alcohol misuse, with research examining the impact of parental illicit drug use being limited. Methodological limitations restrict our ability to make causal inference. Nonetheless, the prevalence of adverse outcomes in children whose parents are nondependent substance misusers highlights the need for practitioners to intervene with this population before a parent has developed substance dependency.

Transglutaminases catalyze the cross-linking and amine incorporation of proteins, and are implicated in various biological phenomena such as blood clotting, wound healing, apoptosis, and cell differentiation. Streptomyces lavendulae Y-200, isolated from soil, produced a substance that inhibited transglutaminases. The inhibitory substance was purified from the cultured medium by procedures of acid precipitation, deoxyribonuclease treatment, and gel filtration chromatography. The partially purified sample was dark brown. The inhibitory activity was stable under acidic, alkaline, and high temperature conditions, and resistant to the treatment with proteinases such as trypsin and Pronase. The molecular weight of the inhibitory substance was estimated to be between 10(4) and 10(5) from its permeability through ultrafilter membranes. The acid hydrolysate of the inhibitory substance contained amino acids and sugars. The inhibitory substance inhibited both calcium-dependent and calcium-independent transglutaminases in a competitive manner with a glutamine substrate. The extent of inhibition caused by the calcium-dependent transglutaminase increased with increasing calcium concentration. The results obtained here may help identify a novel regulatory substance of transglutaminase in biological systems.
Work-family conflict and employee psychiatric disorders: the National Comorbidity Survey.
Frone, M R
2000-12-01
This study examined the relation between work-family conflict and several types of psychiatric disorders: mood, anxiety, substance dependence, and substance abuse. Survey data were obtained from a representative national sample of 2,700 employed adults who were either married or the parent of a child 18 years old or younger. Hierarchical logistic regression analyses revealed that both work-to-family and family-to-work conflict were positively related to having a mood, anxiety, and substance dependence disorder. Depending on the type of work-family conflict and type of disorder, employees who reported experiencing work-family conflict often were 1.99-29.66 times more likely than were employees who reported no work-family conflict to experience a clinically significant mental health problem. No support was found for gender differences.
Association of Substance Use Disorders With Conversion From Schizotypal Disorder to Schizophrenia.

Understanding the role of substance use disorders in conversion from schizotypal disorder to schizophrenia may provide physicians and psychiatrists with important tools for prevention or early detection of schizophrenia. To investigate whether substance use disorders, in particular cannabis use disorder, are associated with conversion to schizophrenia in individuals with schizotypal disorder. This prospective cohort study included a population-based sample of all individuals born in Denmark from January 1, 1981, through August 10, 2014, with an incident diagnosis of schizotypal disorder and without a previous diagnosis of schizophrenia. Follow-up was completed on August 10, 2014, and data were analyzed from March 10, 2017, through February 15, 2018. Information on substance use disorders combined from 5 different registers. Cox proportional hazards regression using time-varying information on substance use disorders and receipt of antipsychotics and adjusted for parental history of mental disorders, sex, birth year, and calendar year were used to estimate hazard ratios (HRs) and 95% CIs for conversion to schizophrenia. A total of 2539 participants with incident schizotypal disorder were identified (1448 men [57.0%] and 1091 women [43.0%]; mean [SD] age, 20.9 [4.4] years). After 2 years, 16.3% (95% CI, 14.8%-17.8%) experienced conversion to schizophrenia. After 20 years, the conversion rate was 33.1% (95% CI, 29.3%-37.3%) overall and 58.2% (95% CI, 44.8%-72.2%) among those with cannabis use disorders. In fully adjusted models, any substance use disorder was associated with conversion to schizophrenia (HR, 1.34; 95% CI, 1.11-1.63). When data were stratified by substance, cannabis use disorders (HR, 1.30; 95% CI, 1.01-1.68), amphetamine use disorders (HR, 1.90; 95% CI, 1.14-3.17), and opioid use disorders (HR, 2.74; 95% CI, 1.38-5.45) were associated with conversion to schizophrenia. These associations were not explained by concurrent use of antipsychotics, functional level before incident schizotypal disorder, or parental history of mental disorders. Substance use disorders, in particular cannabis, amphetamines, and opioids, may be associated with conversion from schizotypal disorder to schizophrenia. However, conversion rates are high even in those without substance use disorders, indicating a need for universal and substance-targeted prevention in individuals with schizotypal disorder.

Experiments conducted with albino rats have evidenced that under the effect of an atherogenic ration the level of lipids and cholesterol in the blood plasma and hepatic tissue and of sillac acids in the blood plasma increased. In the aortic intima the content of acid mucopolysaccharides was rising, this being attended by a concurrent swelling of the main interstitial substance and of the collagen fibers in the subendothelial layer. An addition of apple pectin or of cellulose to the atherogenic ration deferred the development of the mentioned changes.

Data in gender differences in aggression among alcohol and drug dependent subjects are lacking, and no published data are available about gender differences among various subtypes of substance using populations. The goal of this cross-sectional study was to investigate gender differences with regard to types of trait aggression in substance dependent young populations (age: 20-35 years) compared to the general population. Subjects were selected from two clinical samples with a diagnosis of alcohol and drug dependence as well as from a representative sample of the general population. Trait aggression was measured by the four individual subscales of the Buss Perry Aggression Questionnaire (physical-PA, verbal aggression-VA, hostility-H and anger AN) whereas alcohol and drug use were characterized by the AUDIT and EuroADAD scales, respectively. Alcohol and drug dependent subjects showed higher severity on all four subscales of trait aggression compared to the general population. The male-female difference was the highest in the cannabis group. General Linear Model analysis for PA indicated a significant main effect of gender (higher PA for males, p=0.034) with no interaction between substance dependence and gender. For VA, no main effect or interaction for gender was found. Effect sizes for gender difference indicated that while males and females were similar in the control group in the severity in H and A, the level of H and AN was substantially higher in females than in males in the clinical group. These differences between the two genders reached statistical significance in the marijuana group, where female subjects showed a significantly higher severity in these two domains. Compared to the normal sample chronic substance use is associated with higher scores on certain factors of trait aggression, including hostility and anger, in females than in males. Our data suggest that aggression in substance dependent females is more provocable by chronic use of alcohol and drugs than in males. Copyright © 2011 Elsevier Inc. All rights reserved.

Although substance use is associated with reduced educational attainment, this association may be owing to common risk factors such as socioeconomic disadvantage. We tested whether alcohol, nicotine, and illicit drug use and dependence were associated with lifetime educational attainment after controlling for familial background characteristics. Data were from a 1987 questionnaire and a 1992 telephone diagnostic interview of 6,242 male twins (n = 3,121 pairs; mean age = 41.9 years in 1992) who served in the U.S. military during the Vietnam era and therefore, were eligible for educational benefits after military service. Reduced educational attainment (<16 years) was examined in twin pairs discordant for substance use history. Substance use and dependence risk factors assessed were early alcohol and cannabis use, daily nicotine use, lifetime cannabis use, and alcohol, nicotine, cannabis, and any illicit drug dependence. Three significant differences were observed between at-risk twins and their cotwins: Compared to their low-risk cotwins, likelihood of completing <16 years of education was significantly increased for the following: (i) twins who used alcohol before age 18 (adjusted OR = 1.44; 95% CI: 1.02 to 2.05), (ii) twins with a lifetime alcohol dependence diagnosis (adjusted OR = 1.76; 95% CI: 1.27 to 2.44), and (iii) twins who had used nicotine daily for 30 or more days (adjusted OR = 2.54, 95% CI: 1.55 to 4.17). However, no differences in education were observed among twin pairs discordant for cannabis initiation, early cannabis use, or cannabis, nicotine, or any illicit drug dependence. Even in a veteran population with access to military educational benefits, early alcohol use, alcohol dependence, and daily nicotine use remained significantly associated with years of education after controlling for shared familial contributions to educational attainment. The association between other substances and educational attainment was explained by familial factors common to these substance use phenotypes and adult educational attainment.

: Study goals were 2-fold: 1) to examine differences in demographic and clinical characteristics of smokers who fell into 3 diagnostic groups: alcohol abuse/dependence only (ALC), cocaine abuse/dependence only (COC), and mixed alcohol and cocaine abuse/dependence (ALC + COC); and 2) to determine the degree to which diagnostic grouping predicted short-term abstinence from smoking. : Retrospective chart reviews were conducted by using the treatment records of male veterans (N = 175) who participated in a voluntary smoking cessation program during their stay in residential substance dependence treatment. : The ALC group smoked more heavily, had higher levels of nicotine dependence, and reported more emotional problems than the other 2 groups. Short-term abstinence rates were high across the 3 groups (38%, 58%, and 57% for the ALC, COC, and ALC + COC groups, respectively). Lighter smoking at treatment entry, non-white race, and a diagnosis of cocaine abuse/dependence (with or without alcohol abuse/dependence) predicted short-term abstinence in the program. : Substance misusers motivated to quit smoking can initiate smoking abstinence at relatively high rates with the aid of combined pharmacotherapy and intensive group counseling. White subjects who smoke more heavily and have a diagnosis of alcohol abuse/dependence only have lower success rates for abstinence initiation.

We used population-level Australian data to estimate prevalence, age of onset and speed of transitions across stages of alcohol and cannabis use, abuse and dependence, and remission from disorder, and consider the potential impacts that an individual's age cohort's level of substance use predicted transitions into and out of substance use. Data on use, DSM-IV use disorders, and remission from these disorders were collected from participants (n = 8463) in the 2007 Australian National Survey of Mental Health and Wellbeing using the Composite International Diagnostic Interview. Lifetime prevalence (95% confidence interval) of alcohol use, regular use, abuse and dependence were 94.1% (93.3-94.8%), 64.5% (62.9-66.2%), 18.7% (17.4-19.9%) and 4.0% (3.4-4.6%). Lifetime prevalence of cannabis use, abuse and dependence were 19.8% (18.6-20.9%), 4.4% (3.8-5.0%) and 1.9% (1.5-2.4%). Among those with the disorder, rates of remission from cannabis abuse, alcohol abuse, cannabis dependence and alcohol dependence were 90.5% (87.4-93.6%), 86.2% (83.8-88.7%), 79.6% (71.1-88.1%) and 53.8% (46.6-61.0%). Increases in the estimated proportion of people in the respondent's age cohort who used alcohol/cannabis as of a given age were significantly associated with most transitions from use through to remission beginning at the same age. Clear associations were documented between cohort-level prevalence of substance use and personal risk of subsequent transitions of individuals in the cohort from use to greater substance involvement. This relationship remained significant over and above associations involving the individual's age of initiation. These findings have important implications for our understanding of the causal pathways into and out of problematic substance use. © 2018 Australasian Professional Society on Alcohol and other Drugs.

Drug treatments used in substance use disorders are not effective in all patients. To assess the effectiveness of topiramate use in the treatment of substance use disorders. Medline database from January 1966 to December 2013, Cochrane database and clinicaltrials.gov. We used keywords topiramate, addiction, substance abuse, alcohol, tobacco, nicotine, cocaine, methamphetamine, opiate, heroin, benzodiazepine, cannabis, bulimia nervosa, binge eating disorder, gambling. All clinical trials were included. Animal trials, laboratory tests, reviews, answers to writers, case-reports, case series and publications unrelated to the topic were excluded. Twenty-eight articles investigating the efficacy of topiramate in substance use were included. In alcohol-related disorder, several trials and a meta-analysis showed a reduction of days of consumption. In a single-center trial on tobacco-related disorder, topiramate was not found effective in reducing the carbon monoxide expired. In cocaine-related disorder, one single-center trial showed a reduction of days of consumption and two single-center trials have found a trend in favour of topiramate. In alcohol and cocaine co-dependency, a single-center trial found a trend in favour of topiramate. In methamphetamine-related disorder, a multicenter trial found a trend in favour of topiramate. In bulimia nervosa, two single-center trials showed a reduction in binge eating and compensatory behaviours. In binge eating disorder, several trials showed a reduction of binge eating and weight. In gambling, one single-center trial did not show any significant results. There were no randomized controlled trials found in opioid-related disorder, benzodiazepines-related disorder, and cannabis-related disorder. Definition of abstinence and methods to assess the efficacy of topiramate differed between trials. The methodological quality of included trials was variable, especially with no double-blind procedure in eight trials. Topiramate showed interest mainly in alcoholism, binge eating disorder and bulimia nervosa. No definitive conclusions can be reached for other substance use disorders such as nicotine dependence, cocaine dependence, amphetamine dependence or cannabis dependence and for gambling.

The methanol/methylene chloride (CH(3)OH/CH(2)Cl(2)) extract from the stem bark of Mammea africana was showed to possess vasodilating effect in the presence and the absence of N(omega)-nitro-l-arginine methyl ester (l-NAME). The present study was designed to evaluate the effects of the methanol/methylene chloride from the stem bark of Mammea africana. The extract (200 mg/(kg day)) was administered orally in rats treated concurrently with l-NAME (40 mg/(kg day)). l-Arginine (100 mg/(kg day)) and captopril (20 mg/(kg day))were used as positive controls. Bodyweight, systolic arterial blood pressure and heart rate were measured weekly throughout the experiment period (28 days). At the end of treatment, animals were killed and the cardiac mass index evaluated. The aorta was used to evaluate the endothelium-dependant relaxation to carbachol. The aorta contraction induced by noradrenalin was also examined and expressed as a percentage of that induced by KCl. The extract neither affected the body weight nor the heart rate. The extract as captopril completely prevented the development of arterial hypertension. Both the substances failed to restore the endothelium-dependent vascular relaxation and increased the vascular contraction to norepinephrine in relation to KCl contraction. They also significantly reduced the left ventricular hypertrophy induced by l-NAME. These findings are in agreement with the traditional use of Mammea africana in the treatment of arterial hypertension and indicate that it may have a beneficial effect in patients with NO deficiency but will be unable to improve their endothelium-dependent vasorelaxation.

Sensory information processing and alexithymia are two important factors in determining behavioral reactions. Some studies explain the effect of the sensitivity of sensory processing and alexithymia in the tendency to substance abuse. Giving that, the aim of the current study was to compare the styles of sensory information processing and alexithymia between substance-dependent people and normal ones. The research method was cross-sectional and the statistical population of the current study comprised of all substance-dependent men who are present in substance quitting camps of Masal, Iran, in October 2013 (n = 78). 36 persons were selected randomly by simple randomly sampling method from this population as the study group, and 36 persons were also selected among the normal population in the same way as the comparison group. Both groups was evaluated by using Toronto alexithymia scale (TAS) and adult sensory profile, and the multivariate analysis of variance (MANOVA) test was applied to analyze data. The results showed that there are significance differences between two groups in low registration (P < 0.020, F = 5.66), sensation seeking (P < 0.050, F = 1.92), and sensory avoidance (P < 0.008, F = 7.52) as a components of sensory processing and difficulty in describing emotions (P < 0.001, F = 15.01) and difficulty in identifying emotions (P < 0.002, F = 10.54) as a components of alexithymia. However, no significant difference were found between two groups in components of sensory sensitivity (P < 0.170, F = 1.92) and external oriented thinking style (P < 0.060, F = 3.60). These results showed that substance-dependent people process sensory information in a different way than normal people and show more alexithymia features than them.

Cigarette smoking prevalence rates are high among homeless adults (>70%); however, little is known about concurrent tobacco or other nicotine product use (i.e., concurrent use [CU]) in this population. CU may impact smoking quit rates and confer greater risk of health problems within this vulnerable population. This study characterized CU in a sample of homeless smokers and compared cigarette-only smokers (C-OS) to concurrent users (CUs) on participant characteristics and factors known to be associated with smoking cessation. Participants were 178 adult conventional cigarette smokers from a homeless shelter in Dallas, TX. Sociodemographic characteristics, number of homelessness episodes, tobacco dependence, and items characterizing use of several tobacco/nicotine products over the last 30 days including use frequency, reasons for use, and perceived health risks were described. Sociodemographic characteristics, number of homelessness episodes, tobacco dependence, stress, readiness to quit (RTQ) smoking, and number of smoking quit attempts in the last year were compared between the C-OS and CUs groups using t tests and chi-square tests. CU was prevalent (n = 91; 51.1%), and 49.5% of CUs reported the use of ≥2 products in addition to conventional cigarettes. Compared with C-OS, CUs were younger and had more homelessness episodes, higher expired breath carbon monoxide levels, and higher stress (ps < .05). Groups did not differ on sex, race, other dependence indicators, RTQ, or previous quit attempts. CU is common among homeless smokers. CUs and C-OS did not differ in their RTQ smoking, though greater stress among the CUs may represent a hurdle for cessation. © The Author 2014.

Theories of embodied cognition propose that we recognize tools in part by reactivating sensorimotor representations of tool use in a process of simulation. If motor simulations play a causal role in tool recognition then performing a concurrent motor task should differentially modulate recognition of experienced vs. non-experienced tools. We sought to test the hypothesis that an incompatible concurrent motor task modulates conceptual processing of learned vs. non-learned objects by directly manipulating the embodied experience of participants. We trained one group to use a set of novel, 3-D printed tools under the pretense that they were preparing for an archeological expedition to Mars (manipulation group); we trained a second group to report declarative information about how the tools are stored (storage group). With this design, familiarity and visual attention to different object parts was similar for both groups, though their qualitative interactions differed. After learning, participants made familiarity judgments of auditorily presented tool names while performing a concurrent motor task or simply sitting at rest. We showed that familiarity judgments were facilitated by motor state-dependence; specifically, in the manipulation group, familiarity was facilitated by a concurrent motor task, whereas in the spatial group familiarity was facilitated while sitting at rest. These results are the first to directly show that manipulation experience differentially modulates conceptual processing of familiar vs. unfamiliar objects, suggesting that embodied representations contribute to recognizing tools.

Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. Adolescent patients (age range, 12-17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview-Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview-Substance Abuse Module as the criterion standard. Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84% (95% CI, 76%-89%) for identifying nontobacco substance use, 90% (95% CI, 77%-96%) and 94% (95% CI, 89%-96%) for substance use disorders, 100% and 94% (95% CI, 90%-96%) for severe substance use disorders, and 75% (95% CI, 52%-89%) and 98% (95% CI, 95%-100%) for nicotine dependence. No significant differences were found in sensitivity or specificity between the full tool and the Screening to Brief Intervention. A single screening question assessing past-year frequency use for 8 commonly misused categories of substances appears to be a valid method for discriminating among clinically relevant risk categories of adolescent substance use.

IMPORTANCE Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. OBJECTIVE To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. DESIGN, SETTING, AND PARTICIPANTS Adolescent patients (age range, 12–17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview–Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. MAIN OUTCOMES AND MEASURES For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview–Substance Abuse Module as the criterion standard. RESULTS Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84%(95%CI, 76%–89%) for identifying nontobacco substance use, 90% (95%CI, 77%–96%) and 94%(95%CI, 89%–96%) for substance use disorders, 100% and 94%(95%CI, 90%–96%) for severe substance use disorders, and 75% (95%CI, 52%–89%) and 98%(95%CI, 95%–100%) for nicotine dependence. No significant differences were found in sensitivity or specificity between the full tool and the Screening to Brief Intervention. CONCLUSIONS AND RELEVANCE A single screening question assessing past-year frequency use for 8 commonly misused categories of substances appears to be a valid method for discriminating among clinically relevant risk categories of adolescent substance use.

Substance abuse is a worldwide public health concern. Extensive scientific research has shown that screening and brief interventions for substance use disorders administered in primary care provide substantial benefit at relatively low cost. Frontline health clinicians are well placed to detect and treat patients with substance use disorders. Despite effectiveness shown in research, there are many factors that impact the implementation of these practices in real-world clinical practice. Recently, the Ministry of Health and Social Services in Quebec, Canada, issued two policy documents aimed at introducing screening and early intervention for substance abuse into frontline healthcare clinics in Quebec. The current research protocol was developed in order to study the process of implementation of evidence-based addiction treatment practices at three primary care clinics in Montreal (Phase 1). In addition, the research protocol was designed to examine the efficacy of overall policy implementation, including barriers and facilitators to addictions program development throughout Quebec (Phase 2). Phase 1 will provide an in-depth case study of knowledge translation and implementation. The study protocol will utilize an integrated knowledge translation strategy to build collaborative mechanisms for knowledge exchange between researchers, addiction specialists, and frontline practitioners (guided by the principles of participatory-action research), and directly examine the process of knowledge uptake and barriers to transfer using both qualitative and quantitative methodologies. Evaluation will involve multiple measures, time points and domains; program uptake and effectiveness will be determined by changes in healthcare service delivery, sustainability and outcomes. In Phase 2, qualitative methods will be utilized to examine the contextual facilitators and barriers that frontline organizations face in implementing services for substance dependence. Phase 2 will provide the first study exploring the wide-scale implementation of frontline services for substance dependence in the province of Quebec and yield needed information about how to effectively implement mandated policies into clinical practice and impact public health. Findings from this research program will contribute to the understanding of factors associated with implementation of frontline services for substance dependence and help to inform future policy and organizational support for the implementation of evidence-based practices.

We quantify changes in the interfacial pH local to the electrochemical double layer during electrocatalysis, using a concurrent non-faradaic probe reaction. In the absence of electrocatalysis, nanostructured Pt/C surfaces mediate the reaction of H2 with cis-2-butene-1,4-diol to form a mixture of 1,4-butanediol and n-butanol with a selectivity that is linearly dependent on the bulk solution pH. We show that kinetic branching occurs from a common surface-bound intermediate, ensuring that this probe reaction is uniquely sensitive to the interfacial pH within molecular length scales of the surface. We use the pH-dependent selectivity of this reaction to track changes in interfacial pH during concurrent hydrogen oxidation electrocatalysis and find that the local pH can vary dramatically, > 3 units, relative to the bulk value even at modest current densities in well-buffered electrolytes. This work highlights the key role that interfacial pH variation plays in modulating inner-sphere electrocatalysis. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Objective To identify robust predictors of drug dependence. Methods This longitudinal study included 2361 male and female twins from an ongoing longitudinal study at the Center for Antisocial Drug Dependence (CADD) at the University of Colorado Boulder and Denver campuses. Twins were recruited for the CADD project while they were between the ages of 12 and 18. Participants in the current study were on average approximately 15 years of age during the first wave of assessment and approximately 20 years of age at the second wave of assessment. The average time between assessments was five years. A structured interview was administered at each assessment to determine patterns of substance use and Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; Fourth Edition) attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), and drug dependence symptoms. Cloninger’s Tridimensional Personality Questionnaire was also used to assess novelty seeking tendencies (NS). At the second wave of assessment, DSM-IV dependence symptoms were reassessed using the same interview. Path analyses were used to examine direct and indirect mechanisms linking psychopathology and drug outcomes. Results Adolescent substance use, CD, and NS predicted young adult substance dependence, whereas the predictive effects of ADHD were few and inconsistent. Furthermore, CD and NS effects were partially mediated by adolescent substance use. Conclusions Adolescent conduct problems, novelty seeking, and drug use are important indices of future drug problems. The strongest predictor was novelty seeking. PMID:23685327

Both substance use and depression are common in adolescence and often comorbid. Past research has produced conflicting results on whether there is a temporal relationship, and if so, in which direction it operates and how it may vary by sex. We examined the longitudinal associations between substance use frequency and depressive symptoms from adolescence into young adulthood and whether the associations were moderated by sex. With data from Waves I, III, and IV of the National Longitudinal Study of Adolescent to Adult Health (n = 9,816), we used growth curve models to test if depressive symptoms predicted marijuana use or binge drinking frequency (Self-Medication Model) or if substance use frequency predicted depressive symptoms (Stress Model). Moderation by sex and age was tested for both potential pathways. Increases in adolescent depressive symptoms, compared to no symptoms, were associated with a steeper predicted increase in marijuana use frequency from adolescence to young adulthood. Increases in persistent binge drinking or marijuana use frequency had concurrent positive associations with depressive symptoms from adolescence to young adulthood, and these associations were significantly stronger for females compared to males. The results not only support the Self-Medication Model for marijuana use but also provide modest support for the Stress Model, that substance use is associated with depressive symptoms, especially for females.

High levels of childhood traumatic experiences have been observed among substance abusers. There has been insufficient study of the effects of childhood trauma in adulthood. The aim of this study is to research the relationship between childhood trauma, self-esteem, and levels of depression and anxiety in substance-dependent (SD) people. This study took place between March 2012 and April 2013, at Balıklı Rum Hospital (Istanbul) substance dependency clinic. It included 50 patients diagnosed as substance dependent according to the criteria of DSM-IV as compared with 45 healthy controls. The Structured Clinical Interview for DSM-IV Diagnosis (SCID-I) was used to identify Axis I disorders. All other data was collected using a semi-structured socio-demographic questionnaire, the Childhood Trauma Questionnaire (CTQ), the Rosenberg Self Esteem Scale (RSES), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The total scores of the SD group on the CTQ and on its Emotional Abuse/Emotional Neglect (EA/EN), Physical Abuse (PA) and Sexual Abuse (SA) subscales were statistically significant. In relation to the healthy controls, the SD group scored higher on the RSES, BDI and BAI. A correlation was observed between the total scores of SD individuals on the CTQ and their scores on the RSES, BDI and BAI. This study showed high levels of childhood traumatic experiences for SD people and indicates that there may be a relationship between these experiences and their levels of self-esteem, depression and anxiety.

In this article the research directed on development of a technique of definition of time of induction of the self-ignition of substances and materials which is an indicator of the beginning of development of an emergency is conducted. The experiment consisting in supervision over process of self-ignition of coal and oil deposits was the basis for research. On the basis of experimental data the curve expressing analytic - expected dependence of size of temperature of ignition on induction time was constructed. Proceeding from graphical representation of process, functional dependence of time of induction on a temperature indicator was received: y = 16920 • x0 537. By means of known indicators of such substances as bitumen oil oxidized (the combustible solid substance received by oxidation of residual product of oil refining) and tar oil (the combustible solid substance which is residual product of oil refining) and the received algorithm, verification of reliability of the received dependence and a technique of definition of time of induction of spontaneous ignition of deposits of oil in general was carried out. The practical importance of the conducted research is that having data on time of induction of process of self-ignition, by means of preventive measures becomes possible to avoid and prevent accidents in oil and oil processing branches, at the same time loss of property and loss of human life.

Objective: This article examines relationships between reproductive onset and lifetime history of smoking, regular smoking, and nicotine dependence, and cannabis and other illicit drug use. Method: Data were drawn from a young adult cohort of 3,386 female and 2,751 male Australian twins born between 1964 and 1971. Survival analyses were conducted using Cox proportional hazards regression models predicting age at first childbirth from history of substance use or disorder separately by substance class. Other substance use or disorder, including alcohol dependence, as well as sociodemographic characteristics, history of psychopathology, and family and childhood risks, were included as control variables in adjusted models. Results: Regular smoking and nicotine dependence were associated with earlier reproduction, with pronounced effects for women. For women, use of cannabis was associated with early reproduction before age 20, and with delayed reproduction among women who have not reproduced by age 20 or 25. Adjustment for control variables only partially explained these associations. Conclusions: Consistent with research linking adolescent use with sexual risk taking predictive of early childbearing, regular smokers and nicotine-dependent individuals show earlier reproductive onset. In contrast, delays in childbearing associated with use of cannabis are consistent with impairments in reproductive ability and/or opportunities for reproduction. Continued research on risks both upstream and downstream of substance-use initiation and onset of substance-use disorder is needed for causal mechanisms to be fully understood. PMID:19737504

Ten years after the publication of Elaborated Intrusion (EI) Theory, there is now substantial research into its key predictions. The distinction between intrusive thoughts, which are driven by automatic processes, and their elaboration, involving controlled processing, is well established. Desires for both addictive substances and other desired targets are typically marked by imagery, especially when they are intense. Attention training strategies such as body scanning reduce intrusive thoughts, while concurrent tasks that introduce competing sensory information interfere with elaboration, especially if they compete for the same limited-capacity working memory resources. EI Theory has spawned new assessment instruments that are performing strongly and offer the ability to more clearly delineate craving from correlated processes. It has also inspired new approaches to treatment. In particular, training people to use vivid sensory imagery for functional goals holds promise as an intervention for substance misuse, since it is likely to both sustain motivation and moderate craving.

Concurrent Transmission Based on Channel Quality in Ad Hoc Networks: A Game Theoretic Approach
NASA Astrophysics Data System (ADS)
Chen, Chen; Gao, Xinbo; Li, Xiaoji; Pei, Qingqi
In this paper, a decentralized concurrent transmission strategy in shared channel in Ad Hoc networks is proposed based on game theory. Firstly, a static concurrent transmissions game is used to determine the candidates for transmitting by channel quality threshold and to maximize the overall throughput with consideration of channel quality variation. To achieve NES (Nash Equilibrium Solution), the selfish behaviors of node to attempt to improve the channel gain unilaterally are evaluated. Therefore, this game allows each node to be distributed and to decide whether to transmit concurrently with others or not depending on NES. Secondly, as there are always some nodes with lower channel gain than NES, which are defined as hunger nodes in this paper, a hunger suppression scheme is proposed by adjusting the price function with interferences reservation and forward relay, to fairly give hunger nodes transmission opportunities. Finally, inspired by stock trading, a dynamic concurrent transmission threshold determination scheme is implemented to make the static game practical. Numerical results show that the proposed scheme is feasible to increase concurrent transmission opportunities for active nodes, and at the same time, the number of hunger nodes is greatly reduced with the least increase of threshold by interferences reservation. Also, the good performance on network goodput of the proposed model can be seen from the results.

The study was to survey and assess the drug dependence and abuse potential of tramadol with no history of substance abuse. Subjects of tramadol dependence with no prior history of substance abuse were surveyed by interview. Physical dependence of tramadol was assessed using 10 items opiate withdrawal scale (OWS), and psychological dependence was assessed by Addiction Research Center Inventory—Chinese Version (ARCI-CV). Twenty-three male subjects (the median age was 23.4 ± 4.1 years) referred to the addiction unit in Medical Hospital of Guangzhou with tramadol abuse problems were included in this cross-sectional study. The control group included 87 heroin addicts, 60 methamphetamine (MA) abusers, and 50 healthy men. The scores of OWS of tramadol were 0.83–2.30; the mean scores of identifying euphoric effects–MBG, sedative effects–PCAG, and psychotomimetic effects–LSD of ARCI were 8.96 ± 3.08, 6.52 ± 3.25, and 6.65 ± 2.50, respectively, F = 4.927, P < 0.001. Scores of MBG scale in tramadol did not differ from those in heroin and MA groups (P > 0.05) but were higher than those in healthy men (P < 0.05). Tramadol with no history of substance abuse has a clear risk of producing high abuse potential under the long-term infrequent abuse and the high doses. PMID:24151592

This paper describes a comparison of pedestrian compliance at traffic signals with two types of pedestrian phasing: concurrent, where both pedestrians and vehicular traffic are directed to move in the same directions at the same time, and exclusive, where pedestrians are directed to move during their own dedicated phase while all vehicular traffic is stopped. Exclusive phasing is usually perceived to be safer, especially by senior and disabled advocacy groups, although these safety benefits depend upon pedestrians waiting for the walk signal. This paper investigates whether or not there are differences between pedestrian compliance at signals with exclusive pedestrian phasing and those with concurrent phasing and whether these differences continue to exist when compliance at exclusive phasing signals is evaluated as if they had concurrent phasing. Pedestrian behavior was observed at 42 signalized intersections in central Connecticut with both concurrent and exclusive pedestrian phasing. Binary regression models were estimated to predict pedestrian compliance as a function of the pedestrian phasing type and other intersection characteristics, such as vehicular and pedestrian volume, crossing distance and speed limit. We found that pedestrian compliance is significantly higher at intersections with concurrent pedestrian phasing than at those with exclusive pedestrian phasing, but this difference is not significant when compliance at exclusive phase intersections is evaluated as if it had concurrent phasing. This suggests that pedestrians treat exclusive phase intersections as though they have concurrent phasing, rendering the safety benefits of exclusive pedestrian phasing elusive. No differences were observed for senior or non-senior pedestrians. Published by Elsevier Ltd.

To estimate the prevalence of substance use among US physicians. A mailed, anonymous, self-report survey that assessed use of 13 substances and permitted comparison with results of the National Household Survey on Drug Abuse. Rates of physician substance use were weighted to provide national prevalence estimates. A national sample of 9600 physicians, stratified by specialty and career stage, and randomly selected from the American Medical Association master file. The response rate after three mailings was 59%. Demographic characteristics of respondents closely reflected those of the US physician population. Subjects' self-reported use of 13 substances in their lifetime, the past year, and the past month; reasons for use; self-admitted substance abuse or dependence; and whether treatment was received. For controlled prescription substances, respondents were asked to report only use "not prescribed by another physician for a legitimate medical or psychiatric condition." Physicians were less likely to have used cigarettes and illicit substances, such as marijuana, cocaine, and heroin, in the past year than their age and gender counterparts in the National Household Survey on Drug Abuse. They were more likely to have used alcohol and two types of prescription medications--minor opiates and benzodiazepine tranquilizers. Prescription substances were used primarily for self-treatment, whereas illicit substances and alcohol were used primarily for recreation. Current daily use of illicit or controlled substances was rare. Although physicians were as likely to have experimented with illicit substances in their lifetime as their age and gender peers in society, they were far less likely to be current users of illicit substances. The higher prevalence of alcohol use among respondents may be more a characteristic of their socioeconomic class than of their profession. A unique concern for physicians, however, is their high rate of self-treatment with controlled medications--a practice that could increase their risk of drug abuse or dependence. Uniform national guidelines are needed to sensitize medical students and physicians to the dangers of self-treatment with controlled prescription substances.

This study investigates whether certain types of substances are differentially related to certain risky sexual behaviors (RSBs) within the same population and determines whether combination substance use (SU) has additive, redundant or antagonistic effects on RSBs. African-American youth aged 9-19 participated in a large, community-based survey assessing substance use and sexual behaviors. Multilevel modeling was used to predict the differential influence of alcohol, marijuana, and cocaine use on condom use measured in the past 90days and at last intercourse, sex while drunk/high, and number of sexual partners. Tests of the within-participant relations showed that participants increasing their SU over time concurrently increased their RSBs, establishing a strong link between the two behaviors (alcohol: condom β=-0.045, sex while drunk/high β=0.138, sex partners β=0.102; marijuana: condom β=-0.081, sex while drunk/high β=0.255, sex partners β=0.166; cocaine: condom β=-0.091, sex while drunk/high β=0.103, sex partners β=0.031; all p's<0.01). Tests of the between-participant relations showed that, generally, youth reporting less SU across their teenage years were also more likely to report fewer RSBs over this period (alcohol: condom β=-0.128, sex while drunk/high β=0.120, sex partners β=0.169; marijuana: condom β=-0.170, sex while drunk/high β=0.638, sex partners β=0.357; cocaine: condom β=-0.353; all p's<0.05). Moreover, the combination of some substances has unique redundant or antagonistic effects on RSB. Such findings support the consideration of type of SU, and particular combinations of substances, on RSBs in intervention development. Copyright © 2016 Elsevier Ltd. All rights reserved.
