RESUMO
BACKGROUND: Inpatient experiences with interdisciplinary treatment for substance dependence and mental health care are measured using continuous electronic measurements in Norway. Major changes in data collection from cross-sectional surveys to continuous measurements necessitated the revalidation of the instrument. The main purpose of the present study was to determine the psychometric properties of the Patient Experiences Questionnaire for Interdisciplinary Treatment for Substance Dependence - Continuous Electronic Measurement (PEQ-ITSD - CEM). We also aimed to develop a short version of this tool, since completing the original version can be burdensome for some patients. METHODS: The study included adult inpatients (aged ≥ 16 years) who received substance-dependence treatment at 102 different sections in Norway during 2020-2022 (n = 2,850). Factor structure and item performance were assessed. A short version was developed based on the psychometric testing results that included item response theory analysis. RESULTS: The PEQ-ITSD - CEM comprised three empirically based scales with good internal consistency, reliability and validity, which covers treatment and personnel (14 items), milieu (6 items) and outcome (5 items). The results supported a seven-item short version, with three items selected for the treatment and personnel scale, two items for the milieu scale and two items for the outcome scale. CONCLUSIONS: The PEQ-ITSD - CEM can be recommended for future assessments of patient experiences with interdisciplinary treatment for substance dependence in Norway and in other countries with similar healthcare systems. This short-form version can be applied when respondent burden is a crucial issue.

OBJECTIVE: The objective of this systematic review is to determine the tolerability and safety of psilocybin in a variety of psychiatric and substance-dependence conditions. DATA SOURCES: A systematic review was conducted using Embase, PubMed, Cochrane Central, and Web of Science through September 2023 using the following terminology: "psilocybin" AND "mental-disease" OR "substance-dependence" AND "disease-therapy," in addition to other synonymous key words. STUDY SELECTION AND DATA EXTRACTION: Literature reporting acute effects and safety data following the use of psilocybin as the pharmacologic intervention in a clinical trial in adult patients with a psychiatric or substance-dependence condition were included. Following the application of inclusion and exclusion criteria, 16 studies were ultimately included in this review. DATA SYNTHESIS: The most common treatment-emergent adverse effects reported were transient nausea and headache. Transient anxiety was reported as a frequent psychiatric effect, and 3 participants received a benzodiazepine for refractory anxiety during the psilocybin session. Psilocybin demonstrated modest increases in blood pressure and heart rate, and 1 participant received an antihypertensive for sustained hypertension during the psilocybin session. No cases of psilocybin-induced psychosis or Hallucinogen Persisting Perception Disorder were reported. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Treatment resistance remains a concern for psychiatric patients and novel therapies are needed to help alleviate the burden of morbidity and mortality. Psilocybin demonstrates promising acute and long-term safety that may allow for its use in psychiatric or substance-dependence conditions as an alternative to standards of care or in treatment-resistant patients. CONCLUSIONS: Psilocybin has demonstrated tolerability and safety in recent literature that has investigated its therapeutic potential in a variety of psychiatric or substance-dependence conditions.
RESUMO
BACKGROUND: Child laborers are often defined as work that deprives children of their childhood, their potential and their dignity, and that is harmful to physical and mental development. Child laborers are one of the most vulnerable groups in domestic violence. Domestic violence severely affects the physical and mental health, and consequently affects substance dependence and resilience to suicide of these children. Accordingly, it is essential to examine domestic violence, substance dependence, and suicidal ideation in working children. OBJECTIVES: the present study aimed to investigate the relationship between exposure to domestic violence and substance dependence and suicide resilience on the other among child laborers in Iran. METHODS: This study employed cross-sectional research. 600 child laborers were selected via convenience and snow ball sampling from one rehabilitation and welfare center and three charity organization societies in the west of Iran, from January to August 2022. They completed questionnaires. Data were analyzed by SPSS software version 22 and with using descriptive statistics (frequency, percentage, mean and standard deviation) and ANOVA, independent t-test and the multiple linear regression model with a backward strategy. RESULTS: Findings showed that exposure to domestic violence has a strong and direct correlation with substance dependence (r = 0.94, p < 0.001) and strong and indirect correlation with suicide resilience (r =- 0.91, p < 0.001). Also substance dependence has a strong and direct correlation with suicide resilience (r = -0.87, p < 0.001) in child laborers. Variables of substance dependence, suicide resilience, gender, guardian's disease status, living status and age can predict 76.51% of the variance in domestic violence in these children. CONCLUSION: Child laborers experience a lot of domestic violence, which severely affects their suicide resilience and substance dependence in them. Therefore, there is an urgent need for systematic support programs with content (teaching self-care behaviors, stress management, avoiding tense and violent environments) in order to support of these children and reduce domestic violence against them and subsequently reduce substance improve abuse resilience to suicide in these children.

IMPORTANCE: More than 109,000 Americans died of drug overdose in 2022, with 81,231 overdose deaths involving opioids. Methadone, buprenorphine and naltrexone are the most widely used medications for opioid use disorders (MOUD) and the most effective intervention for preventing overdose deaths. However, there is a concern that methadone results in long QT syndrome, which increases the risk for fatal cardiac arrythmias. Currently few studies have systematically evaluated both the short-term and long-term differences in cardiac and mortality outcomes between MOUD. OBJECTIVES: To compare the risks of cardiac arrythmias, long QT syndrome and overall mortality between patients with opioid use disorders (OUD) who were prescribed methadone, buprenorphine or naltrexone. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study based on a multicenter and nationwide database of electronic health records (EHRs) in the United States. The study population was comprised of 144,141 patients who had medical encounters for OUD in 2016-2022, were prescribed MOUD within 1 month following a medical encounter for OUD diagnosis and had no diagnosis of cardiac arrythmias or long QT syndrome before any MOUD prescription. The study population was divided into three cohorts: (1) Methadone cohort (n = 40,938)-who were only prescribed methadone. (2) Buprenorphine cohort (n = 80,055)-who were only prescribed buprenorphine. (3) Naltrexone cohort (n = 5,738)-who were only prescribed naltrexone. EXPOSURES: methadone, buprenorphine, or naltrexone. MAIN OUTCOMES AND MEASURES: Cardiac arrythmias, long QT syndrome, and death. Hazard ratio (HR) and 95% confidence interval (CI) of outcomes at six different follow-up time frames (1-month, 3-month, 6-month, 1-year, 3-year, and 5-year) by comparing propensity-score matched cohorts using Kaplan-Meier survival analysis. RESULTS: Patients with OUD who were prescribed methadone had significantly higher risks of cardiac arrhythmias, long QT syndrome and death compared with propensity-score matched patients with OUD who were prescribed buprenorphine or naltrexone. For the 1-month follow-up, the overall risk for cardiac arrythmias was 1.03% in the Methadone cohort, higher than the 0.87% in the matched Buprenorphine cohort (HR: 1.20, 95% CI: 1.04-1.39); The overall risk for long QT syndrome was 0.35% in the Methadone cohort, higher than the 0.15% in the matched Buprenorphine cohort (HR: 2.40, 95% CI: 1.75-3.28); The overall mortality was 0.59% in the Methadone cohort, higher than the 0.41% in the matched Buprenorphine cohort (HR: 1.48, 95% CI: 1.21-1.81). The increased risk persisted for 5 years: cardiac arrhythmias (HR: 1.31, 95% CI: 1.23-1.38), long QT syndrome (HR: 3.14, 95% CI: 2.76-3.58), death (HR: 1.50, 95% CI: 1.41-1.59). CONCLUSIONS AND RELEVANCE: Methadone was associated with a significantly higher risk for cardiac and mortality outcomes than buprenorphine and naltrexone. These findings are relevant to the development of guidelines for medication selection when initiating MOUD treatment and inform future medication development for OUD that minimizes risks while maximizing benefits.

BACKGROUND: People living in precarious housing or homelessness have higher than expected rates of psychotic disorders, persistent psychotic symptoms, and premature mortality. Psychotic symptoms can be modeled as a complex dynamic system, allowing assessment of roles for risk factors in symptom development, persistence, and contribution to premature mortality. METHOD: The severity of delusions, conceptual disorganization, hallucinations, suspiciousness, and unusual thought content was rated monthly over 5 years in a community sample of precariously housed/homeless adults (n = 375) in Vancouver, Canada. Multilevel vector auto-regression analysis was used to construct temporal, contemporaneous, and between-person symptom networks. Network measures were compared between participants with (n = 219) or without (n = 156) history of psychotic disorder using bootstrap and permutation analyses. Relationships between network connectivity and risk factors including homelessness, trauma, and substance dependence were estimated by multiple linear regression. The contribution of network measures to premature mortality was estimated by Cox proportional hazard models. RESULTS: Delusions and unusual thought content were central symptoms in the multilevel network. Each psychotic symptom was positively reinforcing over time, an effect most pronounced in participants with a history of psychotic disorder. Global connectivity was similar between those with and without such a history. Greater connectivity between symptoms was associated with methamphetamine dependence and past trauma exposure. Auto-regressive connectivity was associated with premature mortality in participants under age 55. CONCLUSIONS: Past and current experiences contribute to the severity and dynamic relationships between psychotic symptoms. Interrupting the self-perpetuating severity of psychotic symptoms in a vulnerable group of people could contribute to reducing premature mortality.

BACKGROUND: Health-related quality of life (HRQoL) is an important element of patient care and clinical research. The aim of this study was to describe HRQoL changes and identify associated factors during a 6-month follow-up of outpatients starting care for alcohol or opioid dependence. METHODS: HRQoL was measured at baseline and 3 and 6 months later using the SF-12. Data on the patients' sociodemographics, clinical characteristics and levels of anxiety and depression were collected using the Hospital Anxiety and Depression Scale (HADS). Repeated-measures analyses were performed to assess factors associated with global HRQoL differences and the evolution of HRQoL indicated by both physical and mental scores (PCS and MCS, respectively). RESULTS: The mean PCS and MCS scores were initially low at 45.4 (SD = 8.6) and 36.0 (SD = 10.9), respectively. The improvement in HRQoL was rapid in the first 3-month period and then slowed and remained stable over the subsequent 3-month period. Being employed (p = 0.012), having no comorbidities (p = 0.014) and having no depression (p = 0.004) were associated with significant differences in the average PCS scores at the 3 time points. Patients who had lower overall HRQoL MCS scores on average were those for whom a medication was initiated (p = 0.009), as was the case for patients with anxiety (p < 0.001) and depression (p < 0.001). Patients with depression at baseline were also those for whom a significantly greater increase in MCS score during the 6 months of follow-up was observed. CONCLUSION: Our findings highlight the importance of screening early psychological distress and considering other factors associated with HRQoL changes in outpatients after the first 3-month period of treatment for substance use disorder.

BACKGROUND: Previous literature has extensively investigated the brain activity during response inhibition in adults with addiction. Inconsistent results including both hyper- and hypo-activities in the fronto-parietal network (FPN) and the ventral attention network (VAN) have been found in adults with addictions, compared with healthy controls (HCs). METHODS: Voxel-wise meta-analyses of abnormal task-evoked regional activity were conducted for adults with substance dependence (SD) and behavioral addiction during response inhibition tasks to solve previous inconsistencies. Twenty-three functional magnetic resonance imaging studies including 479 substance users, 38 individuals with behavioral addiction and 494 HCs were identified. RESULTS: Compared with HCs, all addictions showed hypo-activities in regions within FPN (inferior frontal gyrus and supramarginal gyrus) and VAN (inferior frontal gyrus, middle temporal gyrus, temporal pole and insula), and hyper-activities in the cerebellum during response inhibition. SD subgroup showed almost the same activity patterns, with an additional hypoactivation of the precentral gyrus, compared with HCs. Stronger activation of the cerebellum was associated with longer addiction duration for adults with SD. We could not conduct meta-analytic investigations into the behavioral addiction subgroup due to the small number of datasets. CONCLUSION: This meta-analysis revealed altered activation of FPN, VAN and the cerebellum in adults with addiction during response inhibition tasks using non-addiction-related stimuli. Although FPN and VAN showed lower activity, the cerebellum exhibited stronger activity. These results may help to understand the neural pathology of response inhibition in addiction.

Brain asymmetry reflects left-right hemispheric differentiation, which is a quantitative brain phenotype that develops with age and can vary with psychiatric diagnoses. Previous studies have shown that substance dependence is associated with altered brain structure and function. However, it is unknown whether structural brain asymmetries are different in individuals with substance dependence compared with nondependent participants. Here, a mega-analysis was performed using a collection of 22 structural brain MRI datasets from the ENIGMA Addiction Working Group. Structural asymmetries of cortical and subcortical regions were compared between individuals who were dependent on alcohol, nicotine, cocaine, methamphetamine, or cannabis (n = 1,796) and nondependent participants (n = 996). Substance-general and substance-specific effects on structural asymmetry were examined using separate models. We found that substance dependence was significantly associated with differences in volume asymmetry of the nucleus accumbens (NAcc; less rightward; Cohen's d = 0.15). This effect was driven by differences from controls in individuals with alcohol dependence (less rightward; Cohen's d = 0.10) and nicotine dependence (less rightward; Cohen's d = 0.11). These findings suggest that disrupted structural asymmetry in the NAcc may be a characteristic of substance dependence.

BACKGROUND: Behaviors of substance dependence are common among patients with medication-overuse headache (MOH). Whether MOH, like other substance use disorders, is associated with an increased risk for suicide is unknown. METHODS: In this cross-sectional study, newly diagnosed chronic migraine (CM) patients with or without coexisting MOH were enrolled prospectively. Headache diagnoses were made through face-to-face interviews by headache specialists, and a specifically designed questionnaire was used to collect demographics, headache profiles, Migraine Disability Assessment, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, etc. Suicidal ideation and prior suicide attempt were specifically questioned. RESULTS: In total, 603 CM patients (485F/118M, mean age 42.03 ± 12.18 years) were recruited, including 320 with MOH (257F/63M, mean age 42.8 ± 11.7 years) (53.1%), and 214 (35.5%) and 81 (13.4%) had suicidal ideation and prior suicide attempt, respectively. Among CM patients, the presence of MOH increased the risks of suicidal ideation (odds ratio [OR] = 1.75 [95% CI = 1.20-2.56], p = 0.004) and prior suicide attempt (OR = 1.88 [1.09-3.24], p = 0.024), after controlling for demographics, headache profile, disabilities, symptoms of anxiety and depression, and sleep quality. CONCLUSIONS: In CM patients, MOH is associated with an increased risk for suicidal ideation and prior suicide attempt, which deserves attention for clinicians taking care of headache patients. However, further studies are needed to determine the causal relationship, as well as the underlying pathophysiology.

Child sexual abuse (CSA) and substance use issues later in life have been well documented in the literature. This systematic review from 2009 to 2019 provides an update on what is known about the relationship between CSA and substance use. While the review confirms a clear relationship between CSA and substance use, it also highlights some potential gaps in our current practices, including an acknowledgment of the other risk factors associated with CSA and substance use issues, as well as the need to develop treatment that specifically screens for and addresses CSA in the context of substance use.

Purpose : While recent years have seen a number of studies of social networks in therapeutic communities (TCs) and other residential settings, these have primarily focused on male residents. This paper aims to conduct a longitudinal social network analysis of interpersonal interactions in a TC for women. Design/methodology/approach : The data consists of a longitudinal directed social network of instances of feedback between 56 residents of a 16 bed TC for women over a period of 611 days. Mean age of the participants was 33.1 years, mean length of stay was 133.9 days and 91% of the participants were female. Feedback consisted of written affirmations for prosocial behavior and written corrections for contravening TC norms. Data was analyzed using a latent factor longitudinal social network model. Findings : Residents react to peer intervention in complex ways. Residents reciprocated affirmations (B = 0.14, 95% confidence interval = 0.10, 0.18) and corrections (B = 0.20, 95% CI = 0.13, 0.25). Controlling for reciprocity, participants who received affirmations were more likely to affirm and correct peers (B = 0.10, 95% CI = 0.06, 0.15; B = 0.17, 95% CI = 0.10, 0.23), suggesting that the encouragement offered by affirmations leads to increased activity. Homophily by admission time occurred in both affirmations and corrections (B = 0.23, 95% CI = 0.10, 0.37; B = 0.51, 95% CI = 0.29, 0.74). Originality/value : While affirmations and corrections serve as vehicles for behavioral reinforcement and social learning, they also allow residents to interact in ways that strengthen social bonds.
RESUMO
The majority of research on gender and the opioid epidemic focuses on women as patients, caregivers, or expectant mothers. However, little research approaches men as gendered subjects, despite their dramatically increased risk of opioid overdose. Accordingly, we examined gender differences in prescription opioid use and misuse with specific attention to implications for men using data from the 2017 National Survey on Drug Use and Health. We used design-adjusted, weighted Wald tests and multivariate logistic regression to compare gender differences in rates of prescription opioid use and misuse, prescription opioid sources, primary motivation for misuse, and prescription opioid dependence. We found that although men were significantly less likely than women to report opioid use, they were significantly more likely to report opioid misuse and to misuse prescription opioids primarily to feel good or get high. Among past-year opioid users, men were significantly more likely than women to meet DSM-IV criteria for opioid dependence. Results are consistent with past work on the intersection of masculinity norms and health behaviors. Although gender-specific interventions are typically synonymous with interventions tailored to women, our results suggest that such interventions could alleviate the burden of the opioid epidemic for men as well. Further research studying possible mechanisms that explain men's increased vulnerability to the opioid epidemic is urgently needed to address this growing public health crisis.

BACKGROUND: Although research on health-related quality of life (HRQoL) has increased in the addiction field, few studies have focused on the determinants of HRQoL changes. This study aimed to describe dependent patients' HRQoL changes at a 3-month follow-up and to assess whether satisfaction with care can predict those changes among outpatients starting care for alcohol or opioid dependence. METHODS: HRQoL was measured with the SF-12 at baseline and 3 months later in a prospective cohort of dependent outpatients. Satisfaction was assessed with the EQS-C early after inclusion. Data on sociodemographics, clinical characteristics and patients' levels of anxiety and depression were also collected. A multivariable analysis was performed to identify factors associated with HRQoL changes in both the physical and mental component summary scores (PCS and MCS, respectively). RESULTS: Of the 172 patients included at baseline, a total of 136 patients assessed their satisfaction with care. The mean PCS and MCS scores were initially low, and HRQoL improvement was significant after 3 months for both the PCS and MCS. Never having been married (ß = 5.5; p = 0.001) and a lower baseline PCS score (ß = - 0.6; p < 0.0001) were associated with significant PCS improvement, whereas being legally compelled to undergo drug treatment (ß = - 5.9; p = 0.02) was associated with less PCS change. Higher early satisfaction with care (ß = 0.1; p = 0.02) and a lower baseline MCS score (ß = - 0.7; p < 0.0001) were associated with significant MCS improvement. CONCLUSION: The study supported the hypothesis that greater satisfaction with care may predict HRQoL improvement among dependent outpatients. Further studies are needed to understand the factors that affect patients' early satisfaction to identify areas of improvement and thus improve HRQoL.

While imaging studies have demonstrated volumetric differences in subcortical structures associated with dependence on various abused substances, findings to date have not been wholly consistent. Moreover, most studies have not compared brain morphology across those dependent on different substances of abuse to identify substance-specific and substance-general dependence effects. By pooling large multinational datasets from 33 imaging sites, this study examined subcortical surface morphology in 1628 nondependent controls and 2277 individuals with dependence on alcohol, nicotine, cocaine, methamphetamine, and/or cannabis. Subcortical structures were defined by FreeSurfer segmentation and converted to a mesh surface to extract two vertex-level metrics-the radial distance (RD) of the structure surface from a medial curve and the log of the Jacobian determinant (JD)-that, respectively, describe local thickness and surface area dilation/contraction. Mega-analyses were performed on measures of RD and JD to test for the main effect of substance dependence, controlling for age, sex, intracranial volume, and imaging site. Widespread differences between dependent users and nondependent controls were found across subcortical structures, driven primarily by users dependent on alcohol. Alcohol dependence was associated with localized lower RD and JD across most structures, with the strongest effects in the hippocampus, thalamus, putamen, and amygdala. Meanwhile, nicotine use was associated with greater RD and JD relative to nonsmokers in multiple regions, with the strongest effects in the bilateral hippocampus and right nucleus accumbens. By demonstrating subcortical morphological differences unique to alcohol and nicotine use, rather than dependence across all substances, results suggest substance-specific relationships with subcortical brain structures.

BACKGROUND: Several in-vitro and animal studies suggest that statins may have beneficial effects on clinical outcomes of traumatic brain injury (TBI), however, clinical data are scarce. OBJECTIVES: To examine the association of statin use with TBI clinical outcomes among patients with TBI. METHODS: A retrospective cohort study of Tricare beneficiaries who had a TBI diagnosis, as defined by the Barbell injury diagnosis matrix. Outcomes were defined using ICD-9 codes and included: post-concussion syndrome, neurological disorders, substance dependence or abuse, and psychiatric disorders. Statin-users and non-users were propensity score (PS)-matched using 103 baseline characteristics. RESULTS: Out of 1187 adult patients with a TBI diagnosis (172 statin-users and 1015 nonusers), we PS-matched 70 statin-users to 70 non-users. There were no statistically significant differences in the PS-matched cohort of statin-users in comparison to nonusers for post-concussion syndrome (odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.03-2.20), neurological disorders (OR: 0.60, CI: 0.31-1.16); substance dependence or abuse (OR: 0.80, CI: 0.40-1.60), or psychiatric disorders (OR 0.80, CI: 0.41-1.55). CONCLUSION: This study did not show benefit or harm for statins among survivors of TBI. Our findings do not support the evidence from some animal studies and small randomized controlled trials. Further studies utilizing larger sample sizes are warranted.

Background: Abuse of psychoactive substances may lead to physical and/or physiological dependence on said substances. While a great deal of research has focused on risk factors predicting onset, there has been little research focused on risk factors influencing continued dependence on substances in adulthood following onset early in life. Purpose/Objectives: The present study examined poly-victimization and developmental patterns of anxiety as predictors of continued substance dependence problems. Methods: The Pathways to Desistance data were used in the present study. A subset of this sample was used in analyses comprising 261 juvenile offenders who reported lifetime drug and/or alcohol dependence at baseline. Firth logistic regression was used to estimate the impact that covariates had on the odds that individuals in this subsample had continued substance dependence in adulthood. Results: Results indicated that increased poly-victimization score pertaining to direct victimization at baseline was associated with increased odds of continued substance dependence problems in adulthood. Further, presentation of high and chronic anxiety symptomatology during adolescence was associated with increased risk for continued dependence. Conclusions/Importance: Drug dependent adolescents who demonstrate chronic anxiety and/or have experienced polyvictimization are at-risk for continuity of dependent in adulthood. Youth should be screened for these issues and targeted with treatment.

BACKGROUND: A primary response to the alarming rise in overdose and mortality due to nonmedical prescription opioid (PO) use has been to restrict opioid prescribing; however, little is known about the relationship between obtaining opioids from a physician and overdose risk among people who use POs nonmedically and illicit street drugs. Objectives: Investigate the relationship between non-fatal overdose and acquiring POs exclusively from physicians for the purposes of engaging in nonmedical PO use. Methods: Data were collected between 2013 and 2016 among participants in two harmonized prospective cohort studies of people who use drugs in Vancouver: the At-Risk Youth Study (ARYS) and the Vancouver Injection Drug Users Study (VIDUS). Analyses were restricted to participants who engaged in nonmedical PO use and used generalized estimating equations. Results: Among 599 participants who used POs nonmedically, 82 (14%) individuals reported acquiring POs exclusively from a physician and 197 (33%) experienced a non-fatal overdose at some point over the study period. Acquiring POs exclusively from physicians was significantly and negatively associated with non-fatal overdose in the bivariate analysis (Odds Ratio = 0.60, 95% Confidence Interval (CI): 0.39-0.94) but not the final multivariate analysis (Adjusted Odds Ratio =0.87, 95% CI: 0.53-1.44). Conclusions: Compared to individuals who acquired POs from friends or the streets, participants who acquired POs exclusively from a physician were not at an increased risk of non-fatal overdose. Although responsible opioid prescribing is an important priority, additional strategies to address nonmedical PO use are urgently needed to reduce overdose and related morbidity and mortality.

BACKGROUND: One major concern of long-term opioid therapy (LTOT) for chronic noncancer pain (CNCP) is the risk of abuse of prescribed opioids. OBJECTIVE: To examine the prevalence and predictors of opioid use-related hospitalizations and potential abuse of prescribed opioids by persons with LTOT for CNCP in a sample representative of the German statutory health insurance companies. METHODS: Retrospective cross-sectional study in 2014. Anonymized German health claims database, including 4,028,618 insured individuals of 69 German statutory health insurances. Univariate logistic regression models to evaluate demographic and medical characteristics associated with hospital stays and a diagnosis of mental and behavioral disorders due to alcohol, opioids, tranquilizers, multiple substances and intoxications by narcotic agents in insured individuals with CNCP receiving LTOT. RESULTS: The prevalence of LTOT for CNCP was 0.8%; 9.9% of these insured individuals received high-dose LTOT (≥120 morphine equivalent mg/day). The 1year prevalence of hospital stays with a diagnosis of mental and behavioral disorders due to alcohol, opioids, tranquilizers, multiple substances and intoxications by narcotic agents was 1.75% of persons with LTOT. These diagnoses were strongly associated with prescriptions of tranquilizers (odds ratio [OR] 3.63; 95% confidence interval [CI] 3.03; 4.36) and moderately associated with diagnosis of depression (OR 2.52; 95% CI 2.12; 3.00) and slightly associated with diagnosis of somatoform pain disorder (OR 1.89; 95% CI 1.56; 2.28) and high-dose LTOT (OR 1.81; 95% CI 1.44; 2.27). DISCUSSION: The study is in line with the recommendations of the German national guidelines on long-term opioid therapy of chronic non-cancer pain (LONTS) to avoid concomitant prescription of tranquilizers for CNCP and to carefully select and monitor patients with depression and somatoform pain disorder.

OBJECTIVES: Substance use disorders (SUDs), including those for alcohol, stimulants, tobacco, opioids and cannabis, in patients with bipolar disorder are a major clinical and public health problem, and are present in the majority of these patients. Nonetheless, the development of effective pharmacological treatments for co-occurring SUDs in bipolar illness have not been well-developed and may be an important practical reason for the reduced effectiveness of these medications in community practice. METHODS: We conducted a systematic review of the literature (PubMed, Medline, Google Scholar), and identified N = 29 clinical studies, which evaluated both mental health and SUD outcomes in patients with co-occurring bipolar disorders and SUDs. RESULTS: Our findings suggest the potential of valproate sodium and lamotrigine as preferred pharmacological agents for the treatment of co-occurring psychiatric and substance use outcomes in these patients. However, many of the reviewed studies are of open-label designs and of modest sample sizes. CONCLUSIONS: Thus, given the gaps in our knowledge, recommendations for treatment of this common and important co-morbidity are preliminary. Accordingly, the conduct of larger, randomized controlled trials for this co-morbidity is clearly needed.

BACKGROUND: Substantial substance use disorders and related health conditions emerged dur-ing the mid-20th century and continue to represent a remarkable 21st century global burden of disease. This burden is largely driven by the substance-dependence process, which is a complex process and is influenced by both genetic and environmental factors. During the past few decades, a great deal of pro-gress has been made in identifying genetic variants associated with Substance Use and Dependence (SUD) through linkage, candidate gene association, genome-wide association and sequencing studies. METHODS: Various statistical methods and software have been employed in different types of SUD ge-netic studies, facilitating the identification of new SUD-related variants. CONCLUSION: In this article, we review statistical methods and software that are currently available for SUD genetic studies, and discuss their strengths and limitations.
