Abstract
INTRODUCTION Fentanyl is not yet routinely monitored among methadone maintenance treatment (MMT) patients in Israel. We aimed 1. to evaluate urine fentanyl proportion changes over 3 years and characterize patients' characteristics 2. To study patients' self-report on fentanyl usage, and compare knowledge about fentanyl risk, before and following brief educational intervention. METHODS Fentanyl in the urine of all current MMT patients was tested every 3 months year between 2021 and 2023, and patients with positive urine fentanyl were characterized. Current patients were interviewed using a fentanyl knowledge questionnaire (effects, indications, and risks) before and following an explanation session. RESULTS Proportion of fentanyl ranged between 9.8 and 15.1%, and patients with urine positive for fentanyl (September 2023) were characterized as having positive urine for pregabalin, cocaine, and benzodiazepine (logistic regression). Of the current 260 patients (87% compliance), 78(30%) self-reported of fentanyl lifetime use ("Ever"), and 182 "never" use. The "Ever" group had higher Knowledge scores than the "Never", both groups improved following the explanatory session (repeated measure). The "Ever" group patients were found with urine positive for cannabis and benzodiazepine on admission to MMT, they were younger, did not manage to gain take-home dose privileges and had a higher fentanyl knowledge score (logistic regression). CONCLUSIONS In the absence of routine fentanyl tests, a high knowledge score, shorter duration in MMT, benzodiazepine usage on admission, and current cannabis usage, may hint of the possibility of fentanyl abuse.

Abstract
BACKGROUND Variants in the delta opioid receptor gene, OPRD1, were associated with opioid use disorder and response to treatment. The study goal was to assess whether OPRD1 variants predict survival and retention in methadone maintenance treatment (MMT). METHODS Retention and survival time since admission (June 1993 - June 2022) until leaving treatment (for retention), or at the end of follow-up (Dec 2022) (for retention and survival) were analyzed in 488 patients. Vital data was taken from a national registry. Predictors were estimated using Kaplan-Meier and Cox regression models. RESULTS Longer retention and survival were found for carriers of the T allele of SNP rs204076. This SNP is associated with OPRD1 expression in cortex (GTEx). Carriers of the T allele (n = 251) survived longer compared to non-carriers (24.7 vs. 20.2 years, p = 0.005) and had longer retention (11.2 vs. 8.8 years, p = 0.04). Multivariate analysis identified the T allele as an independent predictor of longer survival time (p = 0.003) and retention (p = 0.009). Additional predictors for survival were no benzodiazepine use after one year in MMT, no hepatitis C, <20 years of opioid usage, and admission at age < 30. Additional predictors for longer retention were no use of other drugs except opioids on admission, and no drugs at one year, as well as methadone dose ≥ 100mg/d at one year and axis I & II DSM-5 psychiatric diagnosis. CONCLUSIONS The OPRD1 SNP rs204076 and non-genetic predictors contribute to survival time and retention in MMT patients.

Abstract
Opioid addiction (OA) is moderately heritable, yet only rs1799971, the A118G variant in OPRM1, has been identified as a genome-wide significant association with OA and independently replicated. We applied genomic structural equation modeling to conduct a GWAS of the new Genetics of Opioid Addiction Consortium (GENOA) data together with published studies (Psychiatric Genomics Consortium, Million Veteran Program, and Partners Health), comprising 23,367 cases and effective sample size of 88,114 individuals of European ancestry. Genetic correlations among the various OA phenotypes were uniformly high (rg > 0.9). We observed the strongest evidence to date for OPRM1: lead SNP rs9478500 (p = 2.56 × 10-9). Gene-based analyses identified novel genome-wide significant associations with PPP6C and FURIN. Variants within these loci appear to be pleiotropic for addiction and related traits.

Abstract
The findings of studies on cannabis use and retention in methadone maintenance treatment (MMT) are inconsistent. To study cannabis use and its relationship to patients' outcomes in MMT with/without lifetime DSM-IV-TR schizophrenia/chronic-psychosis diagnosis. Since June 1993, 877 patients with available lifetime DSM-IV-TR psychiatric diagnosis were followed-up until December 2017. Urine drug screens on admission and after one year were analyzed. Lifetime schizophrenia/psychosis was diagnosed in 50 (5.7%) patients. They did not differ from the other 827 by admission cannabis use (18.0% vs. 12.3%) and had similar 1-year retention rates (76.0% vs.77.0%, respectively). Cumulative retention of the cohort excluding schizophrenia/chronic-psychosis was longer for the 667 patients who did not use cannabis after 1-year (9.1 years, 95%CI 8.4-9.9) compared with the 118 cannabis-users after 1-year (6.0 years, 95% CI 4.8-7.2, p<.001). Among the schizophrenia/chronic-psychosis group, cannabis was not related to retention (38 non-users, 7.9 years 95%CI 5.2-10.5 vs. 9 cannabis-users, 9.9 years, 95% CI 3.8-16.0, p=.5). Survival was shorter for the 41 schizophrenia/chronic-psychosis non-users (15.2 years, 95% CI 12.8-17.7) than for the 719 non-schizophrenia/chronic-psychosis non-users (18.5, 95%CI 17.9-19.2, p = 0.009). However, survival was comparable among the 9 cannabis-users with schizophrenia/chronic-psychosis (20.1, 95% CI 16.2-24.1) and 101 other cohort users (18.6, 95% CI 16.9-20.4). Cannabis use is associated with decreased retention among MMT patients, however the effects of cannabis on schizophrenia/psychosis patients on retention and survival cannot be verified due to the small sample size and the limited data regarding chronicity of cannabis use. Future larger, prospective studies are needed.

Abstract
BACKGROUND Preference for sweet-tasting foods, weight gain, and constipation characterize patients receiving methadone maintenance treatment (MMT). The prevalence of constipation in MMT and its relation to preference for sweet taste and body mass index (BMI) are undetermined. METHODS A random sample of 83 patients was interviewed for constipation with the Patient Assessment Constipation Quality of Life (PAC-QOL) questionnaire. They rated taste intensity and reward of sweet, salty, and sour solutions by means of a nine-point Likert scale. Data on their BMI, drugs in urine, methadone dose, and serum levels were analyzed. RESULTS Forty-two patients reported minimum to severe constipation. They characterized as having longer durations of opioid usage before MMT and worse sleep quality than non-constipated patients (logistic regression). Constipation intensity was inversely correlated with duration in MMT and linearly correlated with the Patient Assessment Constipation Quality of Life score. Patients with constipation rated reward to sweet taste significantly higher with no differences in taste intensity compared to non-constipated patients. Patients with high methadone serum levels (≥750 ng/mL) rated taste intensity significantly lower compared to those with normal methadone serum levels (<750 ng/mL), and the lowest rates were reported among patients with no constipation and high methadone serum levels. CONCLUSIONS Constipation was highly prevalent among MMT patients and associated with poor sleep and lower quality of life. The relation to preference for sweets, as reflected by higher reward rating, strongly supports the need for nutritional intervention to alleviate constipation symptoms and improve quality of life and sleep.

Abstract
Several OPRD1 intronic variants were associated with opioid addiction (OD) in a population-specific manner. This follow-up study aims to further characterize the OPRD1 haplotype pattern of the risk variants in different populations and apply in silico analysis to identify potential causal variants. A population-specific haplotype pattern was revealed based on six OPRD1 eQTL SNPs and five common haplotypes were identified in a sample of European ancestry (CEU). A European-specific haplotype ('Hap 3') that includes SNPs previously associated with OD and is tagged by SNP rs2236861 is more common in subjects with OD. It is quite common (10%) in CEU but is absent in the African sample (YRI) and extends upstream of OPRD1. SNP rs2236857 is most probably a non-causal variant in LD with the causal SNP/s in a population-specific manner. The study provides an explanation for the lack of association in African Americans, despite its high frequency in this population. OD samples homozygous for 'Hap 3' were reanalyzed using a denser coverage of the region and revealed at least 25 potentially regulatory SNPs in high LD. Notably, GTEx data indicate that some of the SNPs are eQTLs for the upstream phosphatase and actin regulator 4 (PHACTR4), in the cortex, and others are eQTLs for OPRD1 and the upstream lncRNA ENSG00000270605, in the cerebellum. The study highlights the limitation of single SNP analysis and the sensitivity of association studies of OPRD1 to a genetic background. It proposes a long-range functional connection between OPRD1 and PHACTR4. PHACTR4, a mediator of cytoskeletal dynamics, may contribute to drug addiction by modulating synaptic plasticity.

Abstract
BACKGROUND Although methadone maintenance treatment (MMT) guidelines are well established, patients' characteristics and outcome change over time may be affected by the legality of cannabis. OBJECTIVE To study trend changes between two clinics over 20 years from Las Vegas (LV) and 27 years from Tel Aviv (TA). METHODS Patients' characteristics at admission, including drugs in urine at first and 13th month were obtained from their medical charts. Changes by year of admission and cumulative retention were analyzed. RESULTS The LV MMT clinic (1724 patients) had a lower one-year retention rate compared to the TA MMT clinic (1014 patients) (46.4% vs. 74.4%, respectively, p < 0.0005), and a higher rate of opioid stop after one year (75.9% vs. 68.8%, respectively, p = 0.003). The age at MMT admission and the retention rates decreased in LV and increased in TA. The prevalence of cannabis and benzodiazepine misuse on MMT admission increased in LV with no change recorded in TA. Cocaine on MMT admission decreased in LV and increased in TA, while amphetamine use increased in LV and decreased in TA. Cox models multivariate analyses found cannabis on admission to predict shorter retention in LV (as younger age male and amphetamines), and cannabis after one year in TA (as did cocaine and opiates after one year and BDZ on admission). CONCLUSION Although cannabis prevalence increased only in LV where it was legalized, it was associated with poor outcomes in both clinics. Younger age, a known poor outcome predictor, may be related to decreased retention in LV.

Abstract
BACKGROUND As CRH-binding protein (CRHBP) SNP rs1500 was associated with reduced cocaine abuse after 1 year in methadone maintenance treatment (MMT) for heroin addiction, we evaluated the association of additional 28 selected SNPs, in 17 stress-related genes, with MMT outcome. METHODS The distribution of genotypes of each SNP by cocaine abuse after 1 year in MMT was assessed under the dominant and recessive models using χ2. Cumulative retention (up to 26.5 years) was studied using Kaplan-Meier analyses. Logistic regression and Cox model were used for multivariate analyses. RESULTS Of a nonselective sample of 404 patients, 25 patients with <50% Europeans/Middle Eastern ancestry were excluded. Of the remaining 379 patients, 330 (87.1%) stayed at least 1 year in treatment. Four SNPs were associated with cocaine abuse after 1 year in MMT. A lower proportion of cocaine abusers was found in the groups of subjects with the following genotypes: arginine vasopressin (AVP) SNP rs2282018 CC, CRHBP rs7728378 TT, galanin rs3136541 TT/TC, and neuropeptide Y receptor Y1 (NPY1R) rs4518200 AA. The following independent variables were associated with lack of cocaine in urine after 1 year (multivariate analyses): CRHBP rs7728378 TT, NPY1R rs4518200 AA, no cocaine in urine on admission, as well as opiate and benzodiazepine use after 1 year in MMT. Cumulative retention (n = 379) was longer in carriers of AVP rs2282018 CC (13.7 years, 95% CI 11.1-16.2) versus TT/TC genotypes (10.5, 95% CI 9.4-11.5) (p = 0.0230) Conclusions: The study suggests that a reduction in cocaine abuse and longer retention among MMT patients is mediated in part by variants in stress-related genes and is a step toward precision medicine.

Abstract
Individuals with substance use disorders are known to suffer from stress, poor sleep, and cognitive impairment. We investigated whether individuals with opioid use disorder would improve cognitive performance following a year of methadone maintenance treatment (MMT). Perceived Stress Scale (PSS), the Pittsburgh Sleep Quality Index (PSQI), and a standardized computerized cognitive battery were administered at admission (T0) to 29 patients, and repeatedly following one year of MMT (T1) by 19 patients. Admission measures did not differ between those who studied once or twice. Patients who perceived very high stress levels (PSS ≥24) at T0 (11, 37.9%) had lower computerized global cognitive scores (67.6±16.2 vs. 90.9±12.5 p≤0.0005). At T1, PSS and PSQI scores improved significantly among 11 patients with no substance abuse, but worsened among 8 with substance abuse (PSS p(interaction)=0.009, p(groups)=0.005, PSQI p(interaction)=0.01, p(groups)=0.04). Global cognitive score improved at T1 for the entire sample (81.8±20.1 to 89.2±13.8, p=0.05). Differentiation by high stress at T0 or by substance abuse at T1 subgroups showed that improvement was observed by those with very low cognitive scores at T0. Patients with poor cognition may improve following one year of MMT, due to stress and substance abuse reduction. Interventions for stress reduction are recommended.

Abstract
Patients' Body Mass Index (BMI) increase during methadone maintenance treatment (MMT), and both Vitamins D and B12 deficiencies may be associated with BMI. We studied the relations between BMI, these vitamins and treatment outcome in patients with opioid use disorder receiving MMT. Vitamin B12 levels were available for 272 patients and Vitamin D levels were available for 260 patients. Of those 112 and 80 respectively had two measures (at admission or thereafter, and while stabilized or after one year in treatment). Patients' BMI levels and long-term retention were analyzed. Vitamin B12 was lower in patients abusing cocaine/amphetamine on admission. Vitamin D did not change over time, but a significant weight gain could be observed in 38 patients whose vitamin D was elevated compared to 42 whose levels were not, (25.4 ± 4.8 to 28.8 ± 5.2 vs. 24.3 ± 3.7 to 25.5 ± 4.0, p(Time) < 0.0005, p(Group) = 0.03, p(interaction) = 0.02). BMI changes correlated with vitamin D levels change (r = 0.26, p = .04). Longer cumulative retention was observed among the elevated vitamin D group (8.1 years, 95% CI 6.3-9.8) in comparison with the non-elevated group (4.8y 95% CI 3.6-6.1, Kaplan Meier, p = .02). Stimulants misuse was associated with low B12 levels. Vitamin D elevation is associated with weight gain and longer retention in treatment.

Abstract
To study the prevalence of perceived high stress among methadone maintenance treatment (MMT) patients, and whether stress can predict outcome, and whether stress may improve during treatment, we studied a sample of 107 MMT patients using Perceived Stress Scale (PSS) questionnaires. We studied if PSS scores on admission predict long-term retention, and we monitored stress indices (PSS, heart rate variability, saliva cortisol) on admission, 6 and 12 months later, to measure changes. Variables included demographic data, history of adverse events, and urine test. A sample of 79 (73.8%) males and 28 (26.2%) females whose age at opioid use onset was 22.1±7.2 years and age at study onset 50.5±10.8 years was studied for PSS. Both high and very-high PSS patients characterized (logistic regression) as abusing benzodiazepine, and with history of depressive symptoms. The very-high PSS group on admission (n=29) had shorter cumulative retention (1.8 years, 95%%CI 1.2-2.4) compared with 50 others (2.8 years, 95%%CI 2.3-3.3, p=0.03). Monitoring stress indices among 25 patients found that no-benzodiazepine and cocaine use on admission, opioid discontinuation after 6 months, and any substance discontinuation after a year were associated with stress reduction. Conclusion: stress level appears to normalize among MMT patients if no other substance is abused.

Abstract
We studied cognitive performance following discharge from a novel rehabilitation facility, treating individuals with psychosis that developed during trips abroad following mandatory military service. Montreal Cognitive Assessment (MoCA), phonetic and semantic fluency, State-Trait Anxiety, and self-Efficiency were administered before discharge, and 3 and 6 months after discharge. Of the 43 participants (30.2% females), 23(54.8%) had cognitive impairment (MoCA <27), and 15(35.7%) had poor phonetic fluency. Anxiety trait and state were high and inversely correlated with self-efficacy (R=-0.48, p = 0.001) and phonetic fluency (R=-0.43, p = 0.004) and was higher among those who experienced physical exposure, females, and those who served in non-combat army units. Six months after discharge, of 32 participants, 28 were working/studying with a 58.1% reduction in smoking and alcohol consumption, and 16 participants stopped substance use. Phonetic fluency improved among the high anxiety state group with no change among the others. High anxiety levels lowered among those who were still using drugs after six months. The anxiety level lowered and 87.1% of the participants were conducting a productive lifestyle at 6 months after discharge, but half still abused cannabis. Bigger sample and longer follow up would be needed to learn more about the impact of rehabilitation.

Abstract
Introduction: Studies which used the Psychopathy Checklist-Revised (PCL-R) among methadone maintenance treatment (MMT) patients focused mostly on methodological issues, without addressing its relationship to patients' misconduct during treatment. This paper tests the hypothesis that high PCL-R scores are related to high rates of drug abuse, and high numbers of behavioral transgressions in MMT during a 7-year period. Material and Methods: 107 MMT patients were recruited from a MMT clinic in Israel, and were administered the PCL-R. The questionnaires results as well as routine drug test findings were recorded between 7/2007 and 11/2007. Seven years later (7/2014), repeated drug test results were analyzed, and the number of behavioral transgressions during the entire period was computed. Results: High levels of psychopathy were related to drug test results indicating any illicit drug use, cocaine use and benzodiazepines misuse at the beginning of study, and limited to benzodiazepines misuse among patients who stayed in treatment at the 7-year follow-up. However, higher scores on different PCL-R facets were significantly associated with different types of drugs. The PCL-R's total score and all but the antisociality facet were positively correlated with a higher number of behavioral transgressions (such as, threats and/or verbal and physical aggression). Conclusions: Administration of the PCL-R during MMT may help identify patients with high illicit drug use levels and a higher chance of committing behavioral transgressions during treatment.

Abstract
There is a reciprocal relationship between the circadian and the reward systems. Polymorphisms in several circadian rhythm-related (clock) genes were associated with drug addiction. This study aims to search for associations between 895 variants in 39 circadian rhythm-related genes and opioid addiction (OUD). Genotyping was performed with the Smokescreen® array. Ancestry was verified by principal/MDS component analysis and the sample was limited to European Americans (EA) (OUD; n = 435, controls; n = 138). Nominally significant associations (p < 0.01) were detected for several variants in genes encoding vasoactive intestinal peptide receptor 2 (VIPR2), period circadian regulator 2 (PER2), casein kinase 1 epsilon (CSNK1E), and activator of transcription and developmental regulator (AUTS2), but no signal survived correction for multiple testing. There was intriguing association signal for the untranslated region (3’ UTR) variant rs885863 in VIPR2, (p = .0065; OR = 0.51; 95% CI 0.31–0.51). The result was corroborated in an independent EA OUD sample (n = 398, p = 0.0036; for the combined samples). Notably, this SNP is an expression quantitative trait locus (cis-eQTL) for VIPR2 and a long intergenic non-coding RNA, lincRNA 689, in a tissue-specific manner, based on the Genotype-Tissue Expression (GTEx) project. Vasoactive intestinal peptide (VIP) is an important peptide of light-activated suprachiasmatic nucleus cells. It regulates diverse physiological processes including circadian rhythms, learning and memory, and stress response. This is the first report of an association of a VIPR2 variant and OUD. Additionally, analysis of combinations of single nucleotide polymorphisms (SNPs) genotypes revealed an association of PER2 SNP rs80136044, and SNP rs4128839, located 41.6 kb downstream of neuropeptide Y receptor type 1 gene, NPY1R (p = 3.4 × 10−6, OR = 11.4, 95% CI 2.7–48.2). The study provides preliminary insight into the relationship between genetic variants in circadian rhythm genes and long non-coding RNA (lncRNAs) in their vicinity, and opioid addiction.

Abstract
Objective: Comorbidity of depression among individuals with opioid addiction is highly prevalent, but their outcome in methadone maintenance treatment (MMT) is not well determined.Methods: Characteristics and outcomes (retention until December 2017) of newly admitted and already (5.5 ± 4 years) in MMT patients with available Hamilton Depression Rating Scale (HAM-D) scores on admission were studied.Results: During psychiatric intake on admission, 70 (21.2%) of 330 patients were diagnosed with high depressive symptoms beyond the cutoff (HAM-D scores ≥ 18). Depressed and nondepressed groups had a similar proportion of females (20% and 23.8%) and age at admission (43.0 ± 10.5 and 43.7 ± 10.4 years), but the depressed group had higher Brief Psychiatric Rating Scale (BPRS) scores (21.4 ± 8.6 vs. 7.0 ± 7.3, respectively; p < .0005), a higher proportion of minority (non-Jewish faith; 28.6% vs.15.4%; p =.02), and a higher proportion of positive urine screening results for cocaine (55.7% vs. 34.4%; p = .001) and for benzodiazepines on admission (74.3% vs. 57.5%; p = .01). Retention after 1 year was similar (79% and 80.7%), but depressed patients had higher rates of cocaine (40.8% vs. 25.5%; p = .05) and benzodiazepine use (59.2% vs. 41.8%; p = .04) and a shorter cumulative retention (5.6 years, 95% confidence interval [CI; 4.3, 7.0]) than the nondepressed patients (6.8 years, 95% CI [6.1, 7.5]; p = .05). Of the 263 evaluated while already in MMT, 23.5% were depressed, characterized with more females (43.5% vs. 23.4%) and with a history of rape (34.5% vs. 7.6%).Conclusions: Newly admitted depressed and nondepressed patients succeeded similarly in the first year retention in treatment, despite their cocaine and benzodiazepine co-abuse. The depression was characterized with females and with rape history in those who were already in MMT. Adequate intervention is recommended for both depressed groups to improve long-term retention and outcome.

Abstract
OBJECTIVES To confirm our previous findings of less cognitive impairments (based on cognitive screening tools) among methadone maintenance treatment (MMT) patients who achieved take-home dose (THD) privileges. METHODS a random sample of 65 Israeli MMT patients were studied using computerised, age and education standardised, cognitive domains (attention, executive function, memory, motor skills), and non-computerised phonetic and semantic verbal fluency. RESULTS Cognitive scores were within ±1 standard deviation (SD) of average for most domains, including non-verbal IQ, attention and motor skills. Verbal fluency and memory were >1 SD below average (mean = 84; z = -1.1 for both). Females were younger than the males and had poorer motor skills (P = 0.005) but better verbal memory (P < 0.0005). Opiate usage duration correlated with reaction time (P = 0.05) and inversely with verbal memory (P = 0.01). Overall cognitive function was poorest among 25 (38.5%) current drug users, and 6 (9.2%) lifetime schizophrenia patients. Cognitive domains were comparable between THD privileges subgroups. CONCLUSIONS Despite heterogeneity in MMT duration, abuse duration, substance use and psychiatric comorbidity, all performed within ±1 SD of average for age and education in most cognitive domains. Our findings challenge the notion of MMT as being synonymous with compromised cognition and may lead to reduced bias regarding cognitive function of MMT patients.

Abstract
Previously we showed that methadone maintenance treatment (MMT) patients displayed difficulties in generalization and reversal learning in the presence of drug-related context, compared to prolonged abstinence individuals. We now tested how history of childhood trauma, affects their reversal learning abilities. Fifty-one MMT patients were evaluated on a performance- based paradigm which assesses the ability to acquire and reverse stimulus-outcome associations in neutral and drug-related context. Patients with a history of childhood trauma (n = 32) as compared to patients without such a history showed decreased ability to learn associations with positive outcome, and had poorer performance in drug compare to neutral-related context. Most importantly, while individuals with childhood trauma history showed higher success rates in conditions of positive to negative reversals, an opposite pattern was observed in conditions of negative to positive reversal; whereas patients with trauma history preformed significantly worse than patients with no history. The results are in line with other studies which tested the effects of childhood trauma both in clinical and in healthy populations. Recognizing this trait that more disturbed by drug related context, may contribute to develop and improve personalized treatments which takes into account the difficulties as well as the strength associated with childhood trauma.

Abstract
Background: The aim of this study was to characterize human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related knowledge and stigma among methadone maintenance treatment (MMT) patients and evaluate the contribution of an educational lecture in reducing risky behavior and unjustified overprotective behavior due to fear and stigma among MMT patients. Methods: Patients from an MMT clinic within a tertiary medical center were invited to an educational lecture on HIV/AIDS. Seventy participants (of current 330) were chosen by a random sample (December 2015), plus at-risk patients and HIV patients. Attendee compliance and change in scores of questionnaires on knowledge (modified HIV-K-Q-22) and on sexual and injection behaviors were studied. Results: Forty-six patients (65.7% compliance) attended the lecture, and their knowledge and behavior scores improved 2 weeks post-lecture (knowledge: from 14.2 ± 3 to 19.0 ± 2.2 [P < .0005], sexual behavior: from 12.1 ± 2.9 to 8.8 ± 3.0 [P < .0005], and injection behavior: from 7.3 ± 6.2 to 0.2 ± 1.3 [P < .0005]). The unjustified fear of proximity to HIV carriers reported by 50% attendees fell to 35% post-lecture. Eight months post-lecture, the scores on knowledge and risky behavior of 21 randomly chosen attendees were still better than pre-lecture scores (knowledge: 15.4 ± 2.3 vs. 17.2 ± 1.8 [paired t test, P = .001], sexual behavior: 13.2 ± 2.3 vs. 9.7 ± 2.9 [P < .0005], and injection behavior: 9.3 ± 5.6 vs. 2.8 ± 3.1 [P < .0005]). Drug abuse and treatment adherence were not related to intervention and to risky behavior. Conclusions: More knowledge, less fear, and less risky behavior immediately and at 8 months post-lecture reflect the success and importance of the educational intervention. Future efforts are needed in order to reduce ignorance and fear associated with HIV/AIDS.

Abstract
Dysregulation of the stress response is implicated in drug addiction; therefore, polymorphisms in stress-related genes may be involved in this disease. An analysis was performed to identify associations between variants in 11 stress-related genes, selected a priori, and heroin addiction. Two discovery samples of American subjects of European descent (EA, n = 601) and of African Americans (AA, n = 400) were analyzed separately. Ancestry was verified by principal component analysis. Final sets of 414 (EA) and 562 (AA) variants were analyzed after filtering of 846 high-quality variants. The main result was an association of a non-coding SNP rs255105 in the CRH (CRF) receptor 2 gene (CRHR2), in the discovery EA sample (Pnominal = .00006; OR = 2.1; 95% CI 1.4-3.1). The association signal remained significant after permutation-based multiple testing correction. The result was corroborated by an independent EA case sample (n = 364). Bioinformatics analysis revealed that SNP rs255105 is associated with the expression of a downstream long intergenic non-coding RNA (lincRNA) gene AC005154.6. AC005154.6 is highly expressed in the pituitary but its functions are unknown. LincRNAs have been previously associated with adaptive behavior, PTSD, and alcohol addiction. Further studies are warranted to corroborate the association results and to assess the potential relevance of this lincRNA to addiction and other stress-related disorders.

Abstract
BACKGROUND Environmental and social trends and patients' characteristics may affect predictors for methadone maintenance treatment (MMT) outcome. METHODS We have expanded our previous study of predictors for MMT outcome (from 619 to 890 patients) and the study period (from 15 to 24 years). Survival and retention in MMT since admission to the MMT clinic (6/1993-6/2016) and until death or study closure (6/2017) were compiled and analyzed. RESULTS Of 890 patients ever admitted (10,146.9 person-years (py)), 237 passed away (116 while in MMT). The mortality rate did not differ between those who stayed or left (2.6 vs. 2.1 per 100 py, p = 0.1), but it was lower among those who stayed ≥1 year during any admission (2.1 vs. 3.3 per 100 py, respectively, p = 0.004). Age <40 years, no hepatitis C or B, no HIV, and no benzodiazepine abuse after one year predicted longer survival (multivariate analyses). No opiate or benzodiazepine abuse after one year, methadone dose ≥100 mg/d, no DSM-IV-TR Axis II diagnosis only, and no direct hospital referral predicted longer retention. Cocaine abuse predicted poor retention and survival among 271 patients admitted during the extended part of the study period. CONCLUSIONS Predictors for retention (associated with MMT outcome) and mortality (associated with pre-treatment comorbidity) after 24 years were similar to those after 15 years. Cocaine abuse as a predictor of both poor retention and poor survival in the later period may reflect the escalating trend for cocaine abuse and should be studied if related to other unmonitored substances.

Abstract
AIM This study assesses whether genetic variants in stress-related genes are associated with prolonged abstinence from heroin in subjects that are not in long-term methadone treatment. METHODS Frequencies of 117 polymorphisms in 30 genes were compared between subjects with history of heroin addiction, either without agonist treatment (n = 129) or in methadone maintenance treatment (n = 923). RESULTS SNP rs1500 downstream of CRHBP and an interaction of SNPs rs10482672 (NR3C1) and rs4234955 (NPY1R/NPY5R) were significantly associated with prolonged abstinence without agonist treatment. CONCLUSION This study suggests that variability in stress-related genes may contribute to the ability of certain subjects to remain in prolonged abstinence from heroin, possibly due to higher resilience to stress.

Abstract
UNLABELLED To compare in methadone maintenance treatment (MMT) gender characteristics and outcomes, all patients ever admitted to Tel Aviv (TA) MMT clinic (N = 837) (June 1993-December 2014) and Las Vegas (LV) MMT clinic (N = 1256) (February 2000-June 2015) were prospectively followed-up (until June 2016). Drugs in urine on admission and after one year and long-term retention up to 23 and 16 years, respectively, were analyzed. Females in both clinics admitted younger than males and following shorter duration of opioid usage (TA: n = 215, 25.7%, age 35.0 ± 7.9 vs. 40.6 ± 9.8 years, p < .0005, duration 12.4 ± 7.0 vs. 18.1 ± 10 years, p < .0005; LV, n = 494, 39.3%, age 38.0 ± 12.6 vs. 39.2 ± 12.8, p = .08 duration 12.9 ± 11.0 vs. 14.8 ± 12.7 years, p = .008). On admission, higher proportion of female than male had positive urine for cocaine in TA (30.4% vs. 21.8%, p = .02) and for benzodiazepine in LVs (33.9% vs. 26.6%, p = .006). After 1 year, both genders had similar retention rate (TA: 76.1% LV: 49.8%) and opioid abstinence (TA: 67.6%, LV: 74.9%), and cumulative retention (TA: 8.2 years, 95% Confidence-Interval 7.6-8.8; LV 2.2 years, 95% confidence interval 2.0-2.4). CONCLUSIONS Clinics differed in their characteristics and outcome, however in both clinic similar outcome between genders despite the difference in characteristics on admission was observed, as did the known women "telescoping effect."

Abstract
Abstract Minority status is associated with mental and physical morbidity, substance dependence, and poor outcomes. To compare characteristics and treatment outcomes between patients from two minority groups in Israel (Christians and Muslims) and patients from the majority population (Jews) in methadone maintenance treatment (MMT), we prospectively studied all patients admitted to our clinic between 1993 and 2012 and followed up until 2013; 655 Jews, 67 Christians, and 37 Muslims. Christian patients differed from Jews and Muslims by younger age at admission to MMT, greater prevalence of drug injectors, and a higher proportion of Hepatitis-C and HIV sera positive. Muslims had comparatively less education and a lower proportion of females. The three groups had similar rates of one-year retention (75.9%) and opiate abstinence (68.1%). They also did not differ in long-term retention (up to 20 years): Muslims 5.5 years (95%CI 3.6-7.4), Christians 7.5 years (95%CI 6-9.1), and Jews 7.6 years (95%CI 7-8.2, p = .3). The Hepatitis-C incidence, however, was higher among the 21 admitted Hepatitis-C seronegative minorities (5.0/100 person years) than the 207 Hepatitis-C seronegative non-minority patients (1.7/100 person years, p=0.03). All groups had good treatment outcomes, except for Hepatitis-C seroconversion, which necessitates a specific preventive intervention among the minority groups.

Abstract
Methadone maintenance treatment (MMT) patients are often under-nourished and overweight. The impact of a nutrition intervention program to improve knowledge about healthy food habits and losing weight was studied. Patients were screened for knowledge about nutrition and body mass index (BMI). Those with a low knowledge score or a BMI ≥26 (n=89) were randomly divided into either intervention (two lectures on healthy nutrition followed by weight monitoring over 6weeks), or controls (weighed at baseline, post-lectures and at study closure). The Yale Food Addiction Scale (YFAS), eating behavior rating, and nutrition knowledge questionnaires were used. Knowledge and food habit scores improved in the intervention group (28.4±4.3, 37.2±3.1, 32.5±3.9 pre-, post- and 6-weeks post-lectures, respectively), with no change in the controls (28.6±3.4, 28.2±4.9, 28.1±5.3, repeated measured p(time)=0.001, p(group)=0.001, p(interaction)=0.001); food habit (intervention: 35.0±7.0, 38.4±5.2, 37.5±5.3, controls: 34.0±6.9, 34.7±6.9, 34.6±7.4, p(time)=0.001, p(group)=0.04, p(interaction)=0.06). BMI scores however did not change and were similar in both groups (p=0.9). Of all patients, 10.1% met the criteria of food addiction according to the YFAS, 40.4% lost weight and 28% gained weight, with no group differences. There were more symptoms of food addiction among the patients who gained weight vs. those who lost weight (3.7±2.0 vs. 2.6±1.8, respectively, p=0.04). We concluded that although weight loss was not observed, intervention is recommended for improving knowledge about nutrition and for fostering healthy eating habits with the aim of reducing diet-related morbidity among all MMT patients. Longitudinal program combined with physical activity is needed to study if may lead to weight loss.

Abstract
AIM This study assesses whether opioid-related gene variants contribute to reduced vulnerability to relapse to heroin in persons who are not treated with μ-opioid receptor agonist. METHODS Genotypes of 71 SNPs, in nine genes, were analyzed for association with long-term abstinence in former heroin-dependents of European/Middle Eastern ancestry, either without agonist treatment (n = 129) or in methadone maintenance treatment (n = 922). RESULTS The functional OPRM1 nonsynonymous SNP rs1799971 (118A>G) showed significant association with long-term abstinence (Ppermutation = 0.03, dominant model, OR: 2.2; 95% CI: 1.5-3.3). CONCLUSION Since the stress axis is regulated in part by β-endorphin, this functional OPRM1 SNP may blunt the endogenous stress response and contribute to reduced vulnerability for relapse.

Abstract
To study whether poor sleep that is known to characterize methadone maintenance treatment (MMT) patients may be related to their past sexual abuse and/or their treatment modality, we compared perceived sleep indices (Pittsburgh Sleep Quality Index (PSQI); Epworth Sleepiness Scale (ESS)) and depression (21-HAM-D) between women with and without sexual abuse history (Childhood Trauma Questionnaire) in MMT and in a non-MMT ("opioid medication-free") in-patient rehabilitation center (MABAT). Twenty-six sexually abused women in MMT had the worst sleep quality scores (PSQI) (10.4 ± 4.2), followed by 15 sexually abused non-MMT women (7.9 ± 4.8), with the lowest score among 13 MMT non-sexually abused women (6.3 ± 4.8, p = 0.03). ESS score and cognitive state scores (Mini Mental State Exam) were similar. Depression (21-HAM-D) score was similar between the two sexually abused (MABAT and MMT) groups (15.3 ± 7.0 and 15.0 ± 6.3, respectively), but was significantly higher than the nonabused MMT group (10.5 ± 6.3, p = 0.03). Logistic regression model for being poor sleeper (PSQI >5), found depression OR = 1.2 (95% CI: 1.1-1.4, p = 0.001), and poor cognitive state (MMSE) OR = 0.6 (95% CI: 0.3-0.9, p = 0.03) to characterize poor sleep. We conclude that poor sleepers were depressed and this characterized sexually abused women in both the MMT and non-MMT groups.

Abstract
BACKGROUND AND OBJECTIVES Methadone maintenance treatment (MMT) is the gold standard for pregnant women with opioid use disorders. Still, low birth-weights were reported, in particular of mothers who became pregnant before admission to MMT. We studied whether an escalating incentive contingency-management approach may contribute to better newborn birth-weights. METHODS A nationwide controlled randomized trial among all Israeli methadone/buprenorphine maintenance treatment (MBMT), newly or already in treatment pregnant women was performed. A modified contingency-management protocol with coupons of escalating value depending upon reduction of drug use, cigarette smoking, and alcohol consumption was compared to standard care arm. Drugs in urine, smoking (Fagerstrom score), alcohol use, and depression were monitored. RESULTS Thirty-five women had 46 pregnancies. In their first pregnancy, 19 from the contingency-management and 16 from the standard care arms were studied. Contingency-management group as compared to the standard care arm included more newly admitted women (36.8% vs. 6.3%, p = .05), with benzodiazepine and cannabis onset at a younger age, and higher proportion of any drug abuse while pregnant (100% vs. 68.8%, p = .01). Fifteen of the contingency-management and 14 of the control arm gave birth (78.9% vs. 87.5%, p = .3) with similar proportions of normal (>2,500 g) birth-weight (71.4% vs. 61.5%, p = .8). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Newborns' birth-weight was comparable among the two study arms indicating no contribution of the contingency-management approach. Small sample and baseline differences between arms might have influenced results. Intensive intervention should be evaluated on a larger scale of participants. (Am J Addict 2017;26:167-175).

Abstract
Stigma attached to methadone maintenance treatment is very common. The objective of the current article is to evaluate the presence of stigma and its relation to the extent of knowledge about methadone maintenance treatment. The authors conducted a survey among methadone maintenance treatment and non-methadone maintenance treatment addiction therapists from different treatment centers in Israel, including methadone maintenance treatment clinics (Ministry of Health) and non-methadone maintenance treatment addiction facilities (Ministry of Social Services), using an anonymous questionnaire about methadone maintenance treatment stigma and knowledge. There were 63 therapists from methadone maintenance treatment clinics (63%) and 46 therapists from the social services department (SSD) non-methadone maintenance treatment addiction facilities (9.2%) who responded. Methadone maintenance treatment versus social services department personnel were older (42.7 ± 12.8 versus 37.5 ± 8.2 years; p = 0.03), with fewer females (48 versus 75%; p = 0.006), and 50% were social workers compared to 100% social workers in the SSD group (p < 0.0005). Stigma score was lower among methadone maintenance treatment personnel compared to the social services department personnel (3 ± 2.5 versus 5.0 ± 3.5; p = 0.0001), while the knowledge score about methadone maintenance treatment was higher among the methadone maintenance treatment personnel (10.3 ± 2.9 versus 7.7 ± 2.8; p < 0.0005). The difference in both the stigma and knowledge scores remained significant after controlling for age, gender, and profession. There was a negative correlation between the stigma and knowledge scores among both the methadone maintenance treatment (R = -0.5, p < 0.0005) and the social services department personnel (R = -0.33, p = 0.03). These results revealed a significant correlation between the presence of stigma and the extent of education and knowledge about methadone maintenance treatment, with ignorance and stigma against methadone maintenance treatment being more pronounced among social services department personnel. An educational intervention, especially among social services department personnel, may benefit people who use opioids and improve the overall quality of treatment for opioid addiction in Israel.

Abstract
BACKGROUND Polymorphisms in genes such as DAT1, 5HTTLPR, D4DR4, and MAO-A have been linked to attention deficit hyperactivity disorder (ADHD) and susceptibility for opiate addiction. We investigated in opiate-addicted parents and their children the rate of ADHD and genetic markers that could predict susceptibility to ADHD and/or opiate addiction. METHODS We studied 64 heroin-addicted, methadone-maintained parents, and their 94 children who had or had not been exposed prenatally to opiates. DNA extracted from mouthwash was assessed for genetic polymorphism for six polymorphic sites of four different genes. Study subjects also filled a variety of questionnaires assessing the rate of ADHD in the parents and children and the children's intelligence quotient. RESULTS Children of opiate-dependent mothers had a higher rate of ADHD compared to those of the opiate-dependent fathers. Opiate-dependent parents have a high risk of being carriers of most risk alleles examined except DRD4EX3 (allele 7). There was no difference whether the addicted parents had or did not have ADHD. CONCLUSIONS Serotonergic and dopaminergic risk alleles seem to be mainly related to opiate dependence with no effect on the occurrence of ADHD. People carrying those polymorphisms are susceptible to opioid addiction and not necessarily to ADHD.

Abstract
AIM This study was designed to determine whether polymorphisms in acetylcholine receptors contribute to opioid dependence and/or cocaine dependence. PATIENTS & METHODS The sample (n = 1860) was divided by drug and ancestry, and 55 polymorphisms (nine genes) were analyzed. RESULTS Of the 20 SNPs that showed nominally significant associations, the association of the African-specific CHRM4 SNP rs2229163 (Asn417=) with cocaine dependence survived correction for multiple testing (Pcorrected = 0.047). CHRM4 is located in a region of strong linkage disequilibrium on chromosome 11 that includes genes associated with schizophrenia. CHRM4 SNP rs2229163 is in strong linkage disequilibrium with several African-specific SNPs in DGKZ and AMBRA1. CONCLUSION Cholinergic receptors' variants may contribute to drug addiction and have a potential role as pharmacogenetic markers.

Abstract
BACKGROUND Weight gain was reported during methadone maintenance treatment (MMT). However, its relation to eating habits and specific risk factors, including methadone dose or serum level, was limited. The aims of this study were to characterize risk factors for weight gain and to study current eating habits, food preferences, and nutrition knowledge. METHODS Patients with available measures of weight and height (body mass index [BMI]) at admission to MMT and at follow-up, when methadone serum levels were determined (after 1 year or when stabilized) (N = 114), were studied (using the Addiction Severity Index [ASI], drugs in urine, methadone doses, and serum levels). In addition, 109 current patients with available earlier (5.8 ± 2.6 years earlier) BMI completed eating behavior rating and nutrition knowledge questionnaires, and their current and earlier BMI were compared. RESULTS The BMI of 114 newly admitted patients increased from 22.5 ± 3.8 to 24.4 ± 4.3 (P < .0005). Once stabilized on methadone, BMI increased further (24.3 ± 4.5 to 25.6 ± 5.0; P < .0005; n = 74), with no change in methadone doses (125.6 ± 32.5 to 128.0 ± 34.1; F = 1.4, P = .2) or serum levels (495.6 ± 263.7 to 539.8 ± 306.2; F = 1.3, P = .2). Repeated-measures analyses revealed that BMI elevation was higher among 45 hepatitis C virus seronegative and 46 non-benzodiazepine-abusing on-admission patients. Those who scored lower on knowledge about healthy diet and showed a higher sweet-foods preference had a higher BMI. CONCLUSION BMI increased over time, but independent of methadone dosage and blood levels. As expected, worse diet habits and a desire for sweet foods are related to higher BMI. Paradoxically, healthier status (i.e., hepatitis C seronegative, no benzodiazepine abuse) at admission is predictive of greater weight gain during MMT. Education about nutrition habits is recommended.

Abstract
IntroductionComorbidity of depression and opioid addiction is highly prevalent, but their outcome in MMT is not consistent.ObjectivesTo compare between depressed and non-depressed MMT patients.MethodsHamilton depression scale scores (taken during a psychiatric assessment) were studied among MMT patients on admission or during treatment (cutoff for depression > 18).ResultsA total of 498 MMT patients were studied. Depression proportion was 22.5%, and 23.2% among 263 who were studied on admission; the depressed vs. non-depressed on admission did not differ in female proportion (19.7% vs. 25.6%), age of admission (43.2 ± 10.4), opiate use onset (21.8 ± 6.3) and education years (9.5 ± 2.8), but had higher proportion of cocaine (55.7% vs. 35.1%, P = 0.005), and benzodiazepine abuse (73.8% vs. 58.4%, P = 0.04). Retention was high and similar (80.3 vs. 82.9% P = 0.7) and of those who stayed one year, cocaine and benzodiazepine were still higher among the depressed patients (cocaine: 43.8% vs. 23.2%, P = 0.03; BDZ: 61.2% vs. 40%, P = 0.01). Compared to the non-depressed, among all study group (n = 498) the depressed patients presented higher proportion of rape history (25% vs. 9.5%, P = 0.001), of suicide attempts (43.8% vs. 25%, P = 0.001) with only a trend of shorter cumulative retention in MMT of mean 9.4y (95% CI 7.8–10.7) vs. 11.5 (95% CI 10.5–12.5, P = 0.07).ConclusionDespite cocaine and benzodiazepine abuse on admission, depressed succeeded similarly to the non-depressed in the first year retention in treatment. Intervention is recommended since admission, as their long-term retention seems to be shorter, later on, and their ability to discontinue cocaine and benzodiazepine abuse is clearly hampered.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
AIM Drug addiction is characterized, in part, by deregulation of synaptic plasticity in circuits involved in reward, stress, cue learning, and memory. This study was designed to assess whether 185 variants in 32 genes central to synaptic plasticity and signal transduction contribute to vulnerability to develop heroin and/or cocaine addiction. METHODS Analyses were conducted in a sample of 1860 subjects divided according to ancestry (African and European) and drug of abuse (heroin or cocaine). RESULTS Eighteen SNPs in 11 genes (CDK5R1, EPHA4, EPHA6, FOSL2, MAPK3, MBP, MPDZ, NFKB1, NTRK2, NTSR1, and PRKCE) showed significant associations (P < 0.01), but the signals did not survive correction for multiple testing. SNP rs230530 in the NFKB1 gene, encoding the transcription regulator NF-kappa-B, was the only SNP indicated in both ancestry groups and both addictions. This SNP was previously identified in association with alcohol addiction. SNP rs3915568 in NTSR1, which encodes neurotensin receptor, and SNP rs1389752 in MPDZ, which encodes the multiple PDZ domain protein, were previously associated with heroin addiction or alcohol addiction, respectively. CONCLUSIONS The study supports the involvement of genetic variation in signal transduction pathways in heroin and cocaine addiction and provides preliminary evidence suggesting several new risk or protective loci that may be relevant for diagnosis and treatment success.

Abstract
BACKGROUND & AIM The dopaminergic pathways have been implicated in the etiology of drug addictions. The aim of this study was to determine if variants in dopaminergic genes are associated with heroin addiction. MATERIALS & METHODS The study includes 828 former heroin addicts and 232 healthy controls, of predominantly European ancestry. Ninety seven SNPs (13 genes) were analyzed. RESULTS Nine nominally significant associations were observed at CSNK1E, ANKK1, DRD2 and DRD3. CONCLUSION The results support our previous report of association of CSNK1E SNP rs1534891 with protection from heroin addiction. CSNK1E interacts with circadian rhythms and DARPP-32 and has been implicated in negative regulation of sensitivity to opioids in rodents. It may be a target for drug addiction treatment.

Abstract
Internet addiction is known to be associated with depression. The Internet Addiction Test (IAT) and the Center for Epidemiologic Studies Depression scale (CES-D) for depression were studied among non-selective methadone maintenance treatment patients from the United States (n = 164) and Israel (n = 113). Thirty percent were not exposed to the internet, and 2.9% (n = 8) had an "occasional/frequent problem." The IAT and CES-D scores correlated significantly (p = .03). The non-exposed group was older, less educated, and had more benzodiazepine abusers. Unlike other behavioral addictions that characterized these patients, the internet addiction problem is rare, but should not be ignored.

Abstract
BACKGROUND Drug addiction is influenced by genetic factors. AIM To determine if genetic variants in the serotonergic and adrenergic pathways are associated with heroin and/or cocaine addiction. SUBJECTS & METHODS The study examined 140 polymorphisms in 19 genes in 1855 subjects with predominantly European or African ancestries. RESULTS A total of 38 polymorphisms (13 genes) showed nominal associations, including novel associations in S100A10 (p11) and SLC18A2 (VMAT2). The association of HTR3B SNP rs11606194 with heroin addiction in the European ancestry subgroup remained significant after correction for multiple testing (p(corrected) = 0.04). CONCLUSION The study strengthens our previous findings of association of polymorphisms in HTR3A, HTR3B and ADRA1A. The study suggests partial overlap in genetic susceptibility between populations of different ancestry and between heroin and cocaine addiction.

Abstract
Drugs of abuse activate the mesolimbic dopaminergic pathway. Genetic variations in the dopaminergic system may contribute to drug addiction. Several processes are shared between cocaine and heroin addictions but some neurobiological mechanisms may be specific. This study examined the association of 98 single nucleotide polymorphisms in 13 dopamine-related genes with heroin addiction (OD) and/or cocaine addiction (CD) in a sample of 801 African Americans (315 subjects with OD ± CD, 279 subjects with CD, and 207 controls). Single-marker analyses provided nominally significant evidence for associations of 24 SNPs) in DRD1, ANKK1/DRD2, DRD3, DRD5, DBH, DDC, COMT and CSNK1E. A DRD2 7-SNPs haplotype that includes SNPs rs1075650 and rs2283265, which were shown to alter D2S/D2L splicing, was indicated in both addictions. The Met allele of the functional COMT Val158Met was associated with protection from OD. None of the signals remained significant after correction for multiple testing. The study results are in accordance with the results of previous studies, including our report of association of DRD1 SNP rs5326 with OD. The findings suggest the presence of an overlap in genetic susceptibility for OD and CD, as well as shared and distinct susceptibility for OD in subjects of African and European descent.

Abstract
Methylphenidate, an amphetamine-like prescription medication for attention deficit hyperactivity disorder (ADHD) was suspected as being abused among methadone maintenance treatment (MMT) patients. We tested its presence in the routine urine monitoring of all patients in both Tel Aviv and Las Vegas MMT clinics. Data on demographic and addiction history, ADHD (Wender Utah Rating Scale), cognitive impairment (Mini Mental State Exam), and lifetime DSM-IV-TR psychiatric diagnosis from admission were retrieved, and retention following 6 months. None of the 190 patients in Las Vegas tested positive for methylphenidate, while 14.7% (45/306) did in Tel Aviv. Abusers were less educated (p = 0.01), had higher ADHD scores (p = 0.02), lower cognitive scores (p = 0.05), and a higher benzodiazepine (BDZ) abuse rate (p < 0.0005), with no difference in age, gender, duration in MMT, cannabis, opiates, and cocaine abuse and infectious disease. Of the methylphenidate abuse 42.2% have take-home methadone dose privileges. Not like opiate use, being methylphenidate positive did not relate to 6-months retention. Compared to Tel Aviv, Las Vegas patients were more educated, with lower BDZ, and cocaine abuse. The greater abuse of methylphenidate among ADHD subjects might indicate their using it as self-medication, raising a possible indication for its prescription for that subgroup of MMT patients. The high rate of methylphenidate abuse in Israel needs future study.

Abstract
OBJECTIVES To characterize lifetime psychiatric diagnosis groups among methadone maintenance treatment (MMT) patients and associations of diagnosis to long-term (up to 20 years) retention and survival either during treatment or post discontinuation. METHODS A total of 758 patients with available psychiatric diagnosis (98% of those ever admitted between June 1993 and June 2012) were followed-up until June 2013. Lifetime psychiatric diagnosis was assessed according to DSM-IV-TR (Axis I, II, I & II, or none). Observed urine samples at 1 and 13 months were positive for drugs if at least one was positive. Survival data were based on the Israel National Population Registry. Survival and retention in MMT were compared (Kaplan Meier) between groups. RESULTS The Axis II (personality disorders) group had the worst mean long-term retention (5.8 years, 95% Confidence Interval (CI) 5.0-6.5) compared with the Axis I, Axis I & II or no psychiatric diagnosis groups (9.6 years, 95% CI 8.8-10.4) (P < 0.0005). Mean survival since admission (16.4 years, 95% CI 15.9-16.9) was similar for all groups. Axis II patients included more males, more drug injectors, were younger at initial opiate use and more likely left treatment before 1 year. CONCLUSIONS Personality and coping mechanisms (Axis II) could be significant obstacles to the success of MMT, warranting special interventions to overcome them.

Abstract
OBJECTIVES Methadone maintenance treatment (MMT) patients may achieve up to a 2-week privilege of methadone take-home doses (THD), which is associated with considerable responsibility. MMT patients are characterized as having poor sleep quality and low cognitive states. We studied sleep indices and cognitive status with respect to THD privileges. METHODS A sample of 123 MMT patients stratified by THD groups was studied. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the cognitive Clock Drawing Test (CDT) were performed. RESULTS Thirty-one of 123 patients never had any THD and 92 did (25 had the maximum of 2 weeks). The never THD had history of longer duration of opiate usage and a shorter period in MMT. They had the highest rates of poor sleep (80.6%, PSQI > 5), daily sleepiness ("fall asleep while talking") (41.9%), and impaired cognitive status (58.1%, CDT < 3), while those who had 2-week privileges had the lowest (56, 8, and 28%, respectively). Logistic regression characterized THD patients as no-benzodiazepine and no-cocaine, short opiate usage duration, low ADHD scores, and no cognitive impairment (CDT = 3) and its interaction with treatment duration. CONCLUSION Privileges that reflect patients' abstinence and rehabilitation were also expanded to be associated with better cognitive states. These finding confirm the THD dispensing performance. Including CDT as part of the decision for dispensing THD may be considered.

Abstract
Following our finding of high rates of obsessive compulsive disorder (OCD) among methadone maintained (MMT) former opiate addict women with a history of childhood sexual abuse, we compared 68 MMT sexually abused women to 48 women from a Sexual Abuse Treatment Center (SATC) without a history of opiate addiction, for clinical-OCD (Yale-Brown Obsessive Compulsive Scale), dissociation (Dissociative Experiences Scale (DES), complex-post-traumatic stress disorder (PTSD) (Structured Interview for Disorders of Extreme Stress - Non-Other Specify), sexual PTSD (the Clinician-Administered PTSD Scale) and trauma events history (Life Event Inventory). MMT patients were treated for longer periods and were older and less educated. Clinical OCD was more prevalent among the MMT patients (66.2% vs. 30.4%, respectively), while complex-PTSD and high dissociation score (DES≥30) were more prevalent among the non-addicts (46.9% vs. 19.1%, and 57.1% vs. 11.8% respectively). The high rate of OCD among sexually abused MMT women was not found in women who are sexually abused non-addicts. As dissociation was rare among the MMT group, it may just be that the opioids (either as street-drugs or as MMT) serve as an external coping mechanism when the access to the internal one is not possible. Future study about OCD and dissociation before entry to MMT are needed.

Abstract
The relationship between vulnerable attachment style, psychopathology, drug abuse, and retention in treatment among patients in methadone maintenance treatment (MMT) was examined by the Vulnerable Attachment Style Questionnaire (VASQ), the Symptom Checklist-90 (SCL-90), and drug abuse urine tests. After six years, retention in treatment and repeated urine test results were studied. Patients with vulnerable attachment style (a high VASQ score) had higher rates of drug abuse and higher psychopathology levels compared to patients with secure attachment style, especially on the interpersonal sensitivity, anxiety, hostility, phobic anxiety, and paranoid ideation scales. Drug abstinence at baseline was related to retention in treatment and to higher rates of drug abstinence after six years in MMT, whereas a vulnerable attachment style could not predict drug abstinence and retention in treatment. Clinical Implications concerning treatment of drug abusing populations and methodological issues concerning the VASQ's subscales are also discussed.

Abstract
Stress is a significant risk factor in the development of drug addictions and in addiction relapse susceptibility. This hypothesis-driven study was designed to determine if specific SNPs in genes related to stress response are associated with heroin and/or cocaine addiction in African Americans. The analysis included 27 genes (124 SNPs) and was performed independently for each addiction. The sample consisted of former heroin addicts in methadone maintenance treatment (n = 314), cocaine addicts (n = 281), and controls (n = 208). Fourteen SNPs showed nominally significant association with heroin addiction (p < 0.05), including the African-specific, missense SNP rs5376 (Asn334Ser) in the galanin receptor type 1 gene (GALR1) and the functional FKBP5 intronic SNP rs1360780. Thirteen SNPs showed association with cocaine addiction, including the synonymous SNPs rs237902, in the oxytocin receptor gene (OXTR), and rs5374 in GALR1. No signal remained significant after correction for multiple testing. Four additional SNPs (GALR1 rs2717162, AVP rs2282018, CRHBP rs1875999, and NR3C2 rs1040288) were associated with both addictions and may indicate common liability. The study provides preliminary evidence for novel association of variants in several stress-related genes with heroin and/or cocaine addictions and may enhance the understanding of the interaction between stress and addictions.

Abstract
After changing the weekend closure of our methadone maintenance clinic from 1 to 2 days, we compared patients' retention in treatment, discount payment privileges, take-home doses, and rate of drugs in urine tests during the 6 months before and after the change. No differences were found in the 6-month retention rate (94.6% and 95.4%, respectively), take-home dose privileges (60.9% and 58%, respectively), or the rate of urines positive to all substance abuse. Expanding closure of the clinic for a 2-day weekend had no adverse effect on treatment parameters, suggesting that a methadone maintenance clinic may keep the same hours as other hospital's outpatient clinics.
