2.  Design of the NIDA Clinical Trials Network Validation Study of Tobacco, Alcohol, Prescription Medications, and Substance Use/Misuse (TAPS) Tool 
Background
Substance use and its associated use disorders are under-detected and under-treated in primary care. There is a need for a clinically useful brief screening and assessment instrument to identify primary care patients with substance use, sub-threshold substance use disorder (SUD), and SUD to facilitate brief intervention and treatment.
Methods
We describe the design of the recently completed National Drug Abuse Treatment Clinical Trials Network’s tobacco, alcohol, prescription medications, and substance use/misuse screen and brief assessment tool validation study. Study aims included to: develop a 2-stage screening and brief assessment tool (TAPS Tool) to detect substance use, problem use, and SUD among adult primary care patients; examine the validity of both the screen component and the TAPS Tool by comparing them to reference standard screening and assessment measures of no use, problem use, and SUD; and determine the feasibility and acceptability of the self-administration and interviewer-administration of the tool. The design included a pilot testing phase (n=30) and the main study of 2,000 adult primary care participants who were randomly assigned in counter-balanced order to have the interviewer-administration or the self-administration of the TAPS Tool followed by the other administration format. Participants’ views of feasibility, acceptability and preference for format of self-administration versus interviewer-administration of the TAPS Tool were assessed. Criterion measures of use and DSM-5 SUDs were administered.
Discussion
The TAPS Tool study builds on prior work to develop a 2-stage clinical tool for facilitating the adoption of screening, brief assessment and treatment for SUDs in primary care.

4.  Performance of the Tobacco, Alcohol, Prescription medication, and other Substance use (TAPS) Tool for substance use screening in primary care patients 
Annals of internal medicine  2016;165(10):690-699.
Background
Substance use is a leading cause of morbidity and mortality that is under-identified in medical practice.
Objective
The Tobacco, Alcohol, Prescription medication, and other Substance use (TAPS) Tool was developed to address the need for a brief screening and assessment instrument that includes all commonly used substances, and fits into clinical workflows. The goal of this study was to assess the performance of the TAPS Tool in primary care patients.
Design
Multi-site study conducted within the National Drug Abuse Treatment Clinical Trials Network, comparing the TAPS Tool against a reference standard measure.
Setting
Five adult primary care clinics.
Participants
2,000 adult patients were consecutively recruited from clinic waiting areas.
Measurements
Interviewer- and self-administered versions of the TAPS Tool were compared to the reference standard modified Composite International Diagnostic Interview (CIDI), which measures problem use and substance use disorders (SUD).
Results
Interviewer- and self-administered versions of the TAPS Tool had similar diagnostic characteristics. For identifying problem use (at a cutoff of 1+), the TAPS Tool had sensitivity 0.93 (95% CI 0.90–0.95) and specificity 0.87 (95% CI 0.85–0.89) for tobacco, and sensitivity 0.74 (95% CI 0.70–0.78), specificity 0.79 (95% CI 0.76–0.81) for alcohol. For problem use of illicit and prescription drugs, sensitivity ranged from 0.82 (95% CI 0.76–0.87) for marijuana to 0.63 (95% CI 0.47–0.78) for sedatives, and specificity was 0.93 or higher. For identifying any SUD, sensitivity was lower, but a score of 2+ greatly increased the likelihood of having a SUD.
Limitations
Low prevalence of some drug classes led to poor precision in some estimates. Research assistants were not blinded to the participant’s TAPS Tool responses when they administered the CIDI.
Conclusions
In a diverse population of adult primary care patients, the TAPS Tool detected clinically relevant problem substance use. While it may also detect tobacco, alcohol, and marijuana use disorders, further refinement is needed before the TAPS Tool can be broadly recommended as a screener for SUD.

5.  The Presence or Absence of QTc Prolongation in Buprenorphine-Naloxone Among Youth with Opioid Dependence 
Journal of addiction medicine  2016;10(1):26-33.
Objective
To evaluate buprenorphine-naloxone effects on the QTc in youth with opioid dependence. Buprenorphine is a partial agonist that is an effective treatment for opioid dependence. Compared to methadone it has a lower risk of QTc prolongation in adults but is less well studied in youth. It may also reduce the risk for torsades de pointes (TdP) an uncommon variant of polymorphic ventricular tachycardia, that can result in syncope, ventricular fibrillation, and sudden death.
Methods
Secondary analysis of ECG data from 95 subjects who participated in a multi-site trial for youth with opioid dependence. Subjects were randomized to a 2-week (DETOX), or a 12-week course of buprenorphine-naloxone (BUP). 12-lead ECGs were done at baseline, weeks 4 and 12, and QTc intervals were hand measured and calculated using Bazett's formula. Increases > 60 milliseconds (ms) were considered clinically significant, and readings > 450 ms (males) and 470 ms (females) indicated a prolonged QTc.
Results
Mean QTc intervals were higher for BUP than DETOX participants at baseline, week 4, and week 12 (p = 0.045), and females had longer mean QTc intervals than males (p < 0.0005). Variations in QTc intervals were observed in some, however none were above 500 ms, the level at which risk for TdP becomes more significant.
Conclusion
In this randomized trial, the mean QTc at baseline, before randomization, was higher in BUP than DETOX patients. Minimal changes in the QTc were seen at 4 and 12-weeks in a few patients in both groups. There was no evidence that buprenorphine-naloxone alone increased the QTc to a level that increased the risk for TdP.

6.  Effective Treatment of Depressive Disorders in Medical Clinics for Adolescents and Young Adults living with HIV: A controlled trial 
Objective
Preliminary test of a manualized, measurement-guided treatment for depression for adolescents and young adults in care at four sites of the Adolescent Trials Network for HIV/AIDS Interventions (ATN).
Design
The U.S. sites were randomly assigned to either a 24-week, combination cognitive behavioral therapy and medication management algorithm (COMB) tailored for youth living with HIV (YLWH) or to treatment as usual (TAU).
Methods
Youth at TAU sites had access to therapists and medication management as needed. COMB site clinicians were trained in the manualized intervention and participated in supervision calls to monitor intervention fidelity.
Results
Over the course of the study with 44 participants, those in COMB, compared to those in TAU, reported fewer depressive symptoms, p<0.01 (as measured by the Quick Inventory for Depression Symptomatology) and were more likely to be in remission, p<0.001, (65% vs.10% at week 24 end of treatment, and 71% vs. 7% at week 48 final follow-up). A greater proportion of COMB participants received psychotherapy (95% vs. 45%, p<0.001) and attended more sessions (12.6 vs. 5, p<0.001) than those in TAU. Viral load decreased in both groups and was associated (p<0.05) with reduction in depressive symptoms.
Conclusions
A 24-week manualized, measurement-guided psychotherapy and medication management algorithm tailored for YLWH was more effective in achieving and sustaining remission from depression than treatment as usual at HIV care clinic sites. Given observed treatment efficacy, this structured combination treatment could be disseminated to medical clinics in order to successfully treat YLWH, who are at particular risk for depression.

9.  Association of Cannabis Use with Opioid Outcomes among Opioid-Dependent Youth 
Drug and alcohol dependence  2013;132(0):342-345.
Objective
Cannabis use is common among opioid-dependent patients, but studies of its association with treatment outcome are mixed. In this secondary analysis, the association of cannabis use with opioid treatment outcome is assessed.
Methods
In the main study, participants (N=152) aged 15-21 years were randomized to receive psychosocial treatments and either a 12-week course of buprenorphine-naloxone with a dose taper to zero in weeks 9-12, or a 2-week detoxification with buprenorphine-naloxone. Drug use was assessed by self-report and urine drug screen at baseline and during study weeks 1-12. The association between cannabis and opioid use at weeks 4, 8, and 12 was examined using logistic regression models.
Results
Participants reported a median of 3.0 days (range=0-30) cannabis use in the past month; half (50.3%; n=77) reported occasional use, one-third reported no use (33.1%; n=50), and one-sixth reported daily cannabis use (16.6%; n=25). Median lifetime cannabis use was 4.0 years (range=0-11) and median age of initiation of use was 15.0 years (range 9-21). Neither past cannabis use (age of initiation and use in the month prior to baseline) nor concurrent use was associated with level of opioid use.
Conclusions
Overall, cannabis use had no association with opioid use over 12 weeks in this sample of opioid-dependent youth. While cannabis use remains potentially harmful, it was not a predictor of poor opioid treatment outcome.

10.  Predictors of Abstinence: NIDA Multi-site Buprenorphine/Naloxone Treatment Trial in Opioid Dependent Youth 
Objective
To examine predictors of opioid abstinence in buprenorphine/naloxone (Bup/Nal) assisted psychosocial treatment for opioid dependent youth
Method
Secondary analyses of data from 152 youth (ages 15–21) randomly assigned to 12 weeks of extended Bup/Nal therapy or up to 2 weeks of Bup/Nal detoxification, both with weekly individual and group drug counseling. Logistic regression models were constructed to identify baseline and during-treatment predictors of opioid positive urines (OPU) at week-12. Predictors were selected based on significance or trend toward significance (i.e. p<0.1) and backward stepwise selection was used, controlling for treatment group, to produce final independent predictors at p ≤ 0.05.
Results
Youth presenting to treatment with past 30-day injection drug use (IDU) and more active medical/psychiatric problems were less likely to have a week-12 OPU. Those with early treatment opioid abstinence (i.e. weeks 1 and 2); and those who received additional non-study treatments during the study were less likely to have a week-12 OPU; and those not completing 12 weeks of treatment were more likely to have an OPU.
Conclusions
Youth with advanced illness (i.e. reporting IDU and additional health problems), and those receiving ancillary treatments to augment study treatment were more likely to have lower opioid use. Treatment success in the first 2 weeks and completion of 12 weeks of treatment were associated with lower rates of OPU. These findings suggest that youth with advanced illness respond well to Bup/Nal treatment, and identify options for tailoring treatment for opioid-dependent youth presenting at community-based settings.

In opioid dependent youth there is substantial attrition from medication-assisted treatment. If youth at risk for attrition can be identified at treatment entry or early in treatment, they can be targeted for interventions to help retain them in treatment.
Methods
Opioid dependent adolescents and young adults (n=152), aged 15–21, were randomized to 12 weeks (BUP, n=74) or 2 weeks of detoxification (DETOX, n=78) with buprenorphine/naloxone (Bup/Nal), both in combination with 12 weeks of psychosocial treatment. Baseline and early treatment related predictors of treatment attrition were identified in each group using bivariate and multivariate logistic regression.
Results
In the DETOX group 36% left between weeks 2 and 4, at the end of the dose taper, while in the BUP group only 8% left by week 4. In the BUP group, early adherence to Bup/Nal, early opioid negative urines, use of any medications in the month prior to treatment entry, and lifetime non-heroin opioid use were associated with retention while prior 30-day hallucinogen use was associated with attrition. In the DETOX group, only use of sleep medications was associated with retention although not an independent predictor. A broad range of other pre-treatment characteristics was unrelated to attrition.
Conclusions
Prompt attention to those with early non-adherence to medication or an early opioid positive urine, markers available in the first 2 weeks of treatment, may improve treatment retention. Extended Bup/ Nal treatment appeared effective in improving treatment retention for youth with opioid dependence across a wide range of demographics, and pre-treatment clinical characteristics.

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

13.  Cost-effectiveness of Extended Buprenorphine-Naloxone Treatment for Opioid-Dependent Youth: Data from a Randomized Trial 
Addiction (Abingdon, England)  2010;105(9):1616-1624.
Introduction
The objective is to estimate cost, net social cost, and cost-effectiveness in a clinical trial of extended buprenorphine-naloxone treatment versus brief detoxification treatment in opioid-dependent youth.
Methods
Economic evaluation of a clinical trial conducted at 6 community outpatient treatment programs from July 2003 to December 2006 including 152 patients aged 15 to 21 years who were randomized to 12 weeks of buprenorphine-naloxone (BUP) or a 14-day taper (DETOX). BUP patients were prescribed up to 24 mg per day for 9 weeks and then tapered to zero at the end of week 12. DETOX patients were prescribed up to 14 mg per day and then tapered to zero on day 14. All were offered twice weekly drug counseling. Data were collected prospectively during the 12-week treatment and at follow-up interviews at months 6, 9, and 12.
Results
The 12-week outpatient study treatment cost was $1514 (p<0.001) higher for BUP relative to DETOX. One-year total direct medical cost was only $83 higher for BUP (p=0.97). The cost-effectiveness ratio of BUP relative to DETOX was $1,376 in terms of 1-year direct medical cost per quality-adjusted life year (QALY) and $25,049 in terms of outpatient treatment program cost per QALY. The acceptability curve suggests that the cost-effectiveness ratio of BUP relative to DETOX has an 86% chance of being accepted as cost-effective for a threshold of $100,000 per QALY.
Conclusions
Extended buprenorphine-naloxone treatment relative to brief detoxification is cost effective in the U.S. health care system for the outpatient treatment of opioid-dependent youth.

14.  HIV risk behavior in treatment-seeking opioid-dependent youth: Results from a NIDA Clinical Trials Network multi-site study 
Objective
To assess baseline rates of and changes in HIV drug and sexual risk behavior as a function of gender and treatment in opioid-dependent youth.
Methods
150 participants were randomly assigned to extended buprenorphine/naloxone therapy for 12 weeks (BUP) or detoxification for 2 weeks (DETOX); all received drug counseling for 12 weeks. HIV risk was assessed at baseline and 4-, 8-, and 12-week follow-ups. Behavioral change was examined using generalized estimating equations.
Results
Baseline rates of past-month HIV risk for females/males were 51%/45% for injection drug use (IDU) (ns), 77%/35% for injection risk (p<.001), 82%/74% for sexual activity (ns), 14%/24% for multiple partners (ns), and 68%/65% for unprotected intercourse (ns). IDU decreased over time (p<.001), with greater decreases in BUP versus DETOX (p<.001) and females versus males in BUP (p<.05). Injection risk did not change for persistent injectors. Sexual activity decreased in both genders and conditions (p<.01), but sexual risk did not.
Conclusions
Overall IDU and sexual activity decreased markedly, particularly in BUP patients and females, but injection and sexual risk behaviors persisted. While extended buprenorphine/naloxone therapy appears to have favorable effects on HIV risk behavior in opioid-dependent youth, risk reduction counseling may be necessary to extend its benefits.

15.  The Added Risk of Opioid Problem Use among Treatment-Seeking Youth with Marijuana and/or Alcohol Problem Use 
Addiction (Abingdon, England)  2010;105(4):686-698.
Objectives
To determine the added risk of opioid problem use (OPU) in youth with marijuana/alcohol problem use (MAPU).
Method
475 youth (ages 14–21 years) with OPU+MAPU were compared to a weighted sample of 475 youth with MAPU only (i.e., no OPU) before and after propensity score matching on gender, age, race, level of care, and weekly use of marijuana/alcohol. Youth were recruited from 88 drug treatment sites participating in eight Center for Substance Abuse Treatment funded grants. At treatment intake, participants were administered the Global Appraisal of Individual Need to elicit information on demographic, social, substance, mental health, HIV, physical and legal characteristics. Odds ratios with confidence intervals were calculated.
Results
The added risk of OPU among MAPU youth was associated with greater comorbidity: higher rates of psychiatric symptoms and trauma/victimization; greater needle-use and sex-related HIV-risk behaviors and greater physical distress. The OPU+MAPU group was less likely to be African American or other race and more likely to be age 15–17 years, Caucasian; report weekly drug use at home and among peers; engage in illegal behaviors and be confined longer; have greater substance abuse severity and poly drug use; and use mental health and substance abuse treatment services.
Conclusions
These findings expand on the existing literature and highlight the substantial incremental risk of OPU on multiple comorbid areas, among treatment-seeking youth. Further evaluation is needed to assess their outcomes following standard drug treatment and to evaluate specialized interventions for this subgroup of severely impaired youth.

16.  Predictors of buprenorphine-naloxone dosing in a 12-week treatment trial for opioid-dependent youth: Secondary analyses from a NIDA Clinical Trials Network study 
Drug and alcohol dependence  2009;107(2-3):253-256.
Introduction
The present investigation examines baseline patient characteristics to predict dosing of buprenorphine-naloxone, a promising treatment for opioid addiction in youths.
Methods
This study of 69 opioid-dependent youths is a secondary analysis of data collected during a National Institute on Drug Abuse (NIDA) Clinical Trials Network study. Outpatients aged 15-21 were randomized to a 12-week buprenorphine-naloxone dosing condition (including 4 weeks of taper). Predictors of dosing included sociodemographic characteristics (gender, race, age, and education), substance use (alcohol, cannabis, cocaine, and nicotine use), and clinical characteristics (pain and withdrawal severity).
Results
Most (75.4%) reported having either “some” (n=40, 58.0 %) or “extreme” (n=12, 17.4%) pain on enrollment. Maximum daily dose of buprenorphine-naloxone (19.7 mg) received by patients reporting “extreme” pain at baseline was significantly higher than the dose received by patients reporting “some” pain (15.0 mg) and those without pain (12.8 mg). In the adjusted analysis, only severity of pain and withdrawal significantly predicted dose. During the dosing period, there were no significant differences in opioid use, as measured by urinalysis, by level of pain.
Conclusion
These data suggest that the presence of pain predicts buprenorphine-naloxone dose levels in opioid-dependent youth, and that patients with pain have comparable opioid use outcomes to those without pain, but require higher buprenorphine-naloxone doses.

18.  Clinical Characteristics of Treatment Seeking Adolescents with Opioid versus Cannabis/Alcohol Use Disorders 
Drug and alcohol dependence  2008;99(1-3):141-149.
Objectives
To assess the clinical characteristics of adolescents with DSM-IV opioid use disorder (OUD) and compare them to adolescents with cannabis/alcohol use disorders.
Method
94 adolescents (ages 14–18 years) with a current OUD and 74 adolescents with a current non-OUD cannabis/alcohol use disorders were recruited from admissions, predominantly residential, to a substance abuse treatment program in Baltimore, Maryland. Participants were assessed cross-sectionally using standardized interviews and self-reports. Chi-square, t-tests and ANCOVA (adjusting for age, gender and treatment setting, race and residence)were performed to determine group differences on demographic, substance use, psychiatric and HIV-risk behaviors; logistic regression analyses, both unadjusted and adjusted for the above five factors were conducted to assess the strength of associations.
Results
The OUD group was more likely to be Caucasian, to have dropped out of school and to live in the suburbs (trend). They also had greater substance use severity with higher proportion of current sedative and multiple SUDs. There were generally no differences in rates of criminal behaviors. Both groups had high rates of current psychiatric disorders (83% vs. 78%, n.s.) but the OUD adolescents reported higher depressive symptoms, mostly in the moderate range. Injection drug use (IDU) and needle sharing was almost exclusive to the OUD group, while both groups reported similar high rates of risky sexual behaviors.
Conclusions
While there were similarities between the two groups, OUD adolescents evidenced greater impairment in academic, substance use, depressive symptom and IDU-related HIV-risk areas. Findings suggest poorer long-term prognosis and highlight the need for specialized interventions for treatment seeking OUD adolescents.

19.  Extended vs Short-term Buprenorphine-Naloxone for Treatment of Opioid-Addicted Youth 
Context
The usual treatment for opioid-addicted youth is detoxification and counseling. Extended medication-assisted therapy may be more helpful.
Objective
To evaluate the efficacy of continuing buprenorphine-naloxone for 12 weeks vs detoxification for opioid-addicted youth.
Design, Setting, and Patients
Clinical trial at 6 community programs from July 2003 to December 2006 including 152 patients aged 15 to 21 years who were randomized to 12 weeks of buprenorphine-naloxone or a 14-day taper (detox).
Interventions
Patients in the 12-week buprenorphine-naloxone group were prescribed up to 24 mg per day for 9 weeks and then tapered to week 12; patients in the detox group were prescribed up to 14 mg per day and then tapered to day 14. All were offered weekly individual and group counseling.
Main Outcome Measure
Opioid-positive urine test result at weeks 4, 8, and 12.
Results
The number of patients younger than 18 years was too small to analyze separately, but overall, patients in the detox group had higher proportions of opioid-positive urine test results at weeks 4 and 8 but not at week 12 ( χ22 = 4.93, P = .09). At week 4, 59 detox patients had positive results (61%; 95% confidence interval [CI] = 47%-75%) vs 58 12-week buprenorphine-naloxone patients (26%; 95% CI = 14%-38%). At week 8, 53 detox patients had positive results (54%; 95% CI = 38%-70%) vs 52 12-week buprenorphine-naloxone patients (23%; 95% CI = 11%-35%). At week 12, 53 detox patients had positive results (51%; 95% CI = 35%-67%) vs 49 12-week buprenorphine-naloxone patients (43%; 95% CI = 29%-57%). By week 12, 16 of 78 detox patients (20.5%) remained in treatment vs 52 of 74 12-week buprenorphine-naloxone patients (70%; χ12 = 32.90, P < .001). During weeks 1 through 12, patients in the 12-week buprenorphine-naloxone group reported less opioid use ( χ12 = 18.45, P < .001), less injecting ( χ12 = 6.00, P = .01), and less nonstudy addiction treatment ( χ12 = 25.82, P < .001). High levels of opioid use occurred in both groups at follow-up. Four of 83 patients who tested negative for hepatitis C at baseline were positive for hepatitis C at week 12.
Conclusions
Continuing treatment with buprenorphine-naloxone improved outcome compared with short-term detoxification. Further research is necessary to assess the efficacy and safety of longer-term treatment with buprenorphine for young individuals with opioid dependence.

20.  Carbapenem-Resistant Pseudomonas aeruginosa in Malaysia Producing IMP-7 β-Lactamase 
Antimicrobial Agents and Chemotherapy  2002;46(10):3286-3287.
We have isolated and identified a carbapenem-resistant Pseudomonas aeruginosa strain from Malaysia that produces an IMP-7 metallo-β-lactamase. This isolate showed high-level resistance to meropenem and imipenem, the MICs of which were 256 and 128 μg/ml, respectively. Isoelectric focusing analyses revealed pI values of >9.0, 8.2, and 7.8, which indicated the possible presence of IMP and OXA. DNA sequencing confirmed the identity of the IMP-7 determinant.
