Social workers are in an ideal position to address the need for increased access to screening, brief intervention, and referral to treatment (SBIRT) for substance use disorder. This pre-post study explores the effects of SBIRT education and training among social work students from three campus environments (traditional, online, and satellite). Results demonstrated that participation in online training was related to increased levels of confidence, sense of responsibility, and practice of SBIRT and a decrease in perceived barriers. On-campus students showed the greatest post-training gains in confidence to use SBIRT. Results suggest that SBIRT education and training is beneficial for students from various backgrounds and should be included in social work students' core clinical practice curriculum.

Background: Cocaine use disorder (CUD) is a major public health problem for which there is no approved pharmacotherapy. The primary purpose of this study was to evaluate the ability of lorcaserin, a 5-hydroxytryptamine2 C (5-HT2 C) receptor agonist, to facilitate abstinence in individuals seeking treatment for CUD. Methods: This was a 12-site, randomized, parallel arm study with a 13-week Treatment Phase that included a 1week, single-blind run-in period when all participants received twice daily 15 mg acetazolamide capsules (a medication adherence marker), followed by randomization to either twice daily 10 mg lorcaserin or placebo capsules for the remaining 12 weeks. Pre-randomization data were utilized in an enrichment strategy aimed at achieving high levels of medication adherence and low placebo response rates in a subgroup of participants that qualified for the "efficacy population." For lorcaserin vs. placebo, the primary efficacy endpoint was the proportion of participants in the efficacy population achieving abstinence during the last three weeks of treatment, as evidenced by self-report of no cocaine use, confirmed by urine testing. Results: Within the efficacy population, 1.1% of 91 participants receiving lorcaserin and 4.3% of 92 receiving placebo achieved abstinence during the last 3 weeks of treatment. Among all randomized participants, 2.5% of 118 receiving lorcaserin and 5.6% of 124 receiving placebo achieved similar abstinence. Study participants receiving lorcaserin exhibited significantly greater reductions in body weight and BMI, indicating that medication adherence was sufficient to produce a pharmacological effect. Conclusions: Twice daily 10 mg lorcaserin failed to demonstrate efficacy in the treatment of CUD.

Incidental findings in research with human participants may have implications for a person's present health or future health outcomes. Current guidelines focus on methods for handling and reporting incidental findings from biological test data but incidental findings might also arise from non-biological tests. This article presents three examples in which the results from non-biological test data can be predictive of future disease and should be disclosed to research participants. It is intended to increase awareness and facilitate further discussion about the reporting of incidental findings from non-biological data.

PURPOSE:Many studies have found evidence that research subjects engage in deceptive practices while participating in health-related studies. Little is known, however, about how often subjects use deception and the percentage of studies a typical subject will contaminate with false data. This study examined the frequency of use of different types of deception among a sample of subjects who admit to using deception.METHODS:A sample of 59 subjects who had participated in at least two health-related studies in the past 12 months and admitted to using deception in at least one were interviewed. Subjects were asked a series of questions about concealing information and fabricating information to gain entry into studies. Subjects were also asked about falsifying data after being enrolled in a health-related study. All study data reported pertains to only subjects who reported using deception in health-related studies and is based on subjects' study participation only within the last 12 months from the date of the interview.RESULTS:Subjects who conceal information in order to enroll in trials reported using concealment in about two thirds (67%) of the trials they participated in over the past 12 months. On average, these subjects' use of concealment was highest for mental health information (58% of studies) and physical health information (57% of studies). The average frequency of fabricating information in order to enroll in trials was 53% with exaggerating health symptoms (45% of studies) and pretending to have a health condition (39% of studies) as the two most widely used strategies. Subjects who falsify study data after enrollment reported doing so 40% of the time. These subjects falsely reported improvement in the health condition being studied in 38% of the trials they took part in. Subjects who admitted to throwing away study medication to create the appearance of compliance reported doing so 32% of the time.LIMITATIONS:Although this study provides evidence that subjects who admit to using deception contaminate a high percentage of studies, larger and more geographically diverse samples are needed to understand the full extent of the problem of deceptive subjects in research. Regional economic, cultural, or organizational factors may be related to the rate of subjects using deception. It is also possible that this sample underrepresents the use of deception as there are likely subjects who use deception that would be unwilling to admit the extent of this behavior.CONCLUSION:Deceptive subject's behavior poses a threat to the integrity of research findings. Given that deceptive subjects contaminate a high percentage of studies they take part in by concealing information, fabricating information, and falsifying study data after enrollment, efforts to identify and exclude these subjects is important to the integrity of research findings. Strategies to exclude deceptive subjects from health research should be used to inform study designs. Widespread adoption of research subject identity registries could greatly reduce the scope of studies that a single deceptive subject could contaminate. Technological solutions that provide an objective measure of medication compliance may be valuable tools for limiting fraudulent reports of compliance.

The estimated probability of progressing from phase 3 analgesic clinical trials to regula-tory approval is approximately 57%, suggesting that a considerable number of treatments with phase 2 trial results deemed sufficiently successful to progress to phase 3 do not yield positive phase 3 results. Deficiencies in the quality of clinical trial conduct could account for some of this failure. An Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials meeting was convened to identify potential areas for improvement in trial conduct in order to improve assay sensitivity (ie, ability of trials to detect a true treatment effect). We present recommendations based on presentations and discussions at the meeting, literature reviews, and iterative revisions of this article. The recommendations relate to the following areas: 1) study design (ie, to promote feasibility), 2) site selection and staff training, 3) participant selection and training, 4) treatment adherence, 5) data collection, and 6) data and study monitoring. Implementation of these recommendations may improve the quality of clinical trial data and thus the validity and assay sensitivity of clinical trials. Future research regarding the effects of these strategies will help identify the most efficient use of resources for conducting high quality clinical trials. Perspective: Every effort should be made to optimize the quality of clinical trial data. This manuscript discusses considerations to improve conduct of pain clinical trials based on research in multiple medical fields and the expert consensus of pain researchers and stakeholders from academia, regulatory agencies, and industry.

BACKGROUND:Several single-site alcohol treatment clinical trials have demonstrated efficacy for immediate-release (IR) gabapentin in reducing drinking outcomes among individuals with alcohol dependence. The purpose of this study was to conduct a large, multisite clinical trial of gabapentin enacarbil extended-release (GE-XR) (HORIZANT® ), a gabapentin prodrug formulation, to determine its safety and efficacy in treating alcohol use disorder (AUD). METHODS:Men and women (n = 346) who met DSM-5 criteria for at least moderate AUD were recruited across 10 U.S. clinical sites. Participants received double-blind GE-XR (600 mg twice a day) or placebo and a computerized behavioral intervention (Take Control) for 6 months. Efficacy analyses were prespecified for the last 4 weeks of the treatment period. RESULTS:The GE-XR and placebo groups did not differ significantly on the primary outcome measure, percentage of subjects with no heavy drinking days (28.3 vs. 21.5, respectively, p = 0.157). Similarly, no clinical benefit was found for other drinking measures (percent subjects abstinent, percent days abstinent, percent heavy drinking days, drinks per week, drinks per drinking day), alcohol craving, alcohol-related consequences, sleep problems, smoking, and depression/anxiety symptoms. Common side-effects were fatigue, dizziness, and somnolence. A population pharmacokinetics analysis revealed that patients had lower gabapentin exposure levels compared with those in other studies using a similar dose but for other indications. CONCLUSIONS:Overall, GE-XR at 600 mg twice a day did not reduce alcohol consumption or craving in individuals with AUD. It is possible that, unlike the IR formulation of gabapentin, which showed efficacy in smaller Phase 2 trials at a higher dose, GE-XR is not effective in treating AUD, at least not at doses approved by the U.S. Food and Drug Administration for treating other medical conditions.

Placebo-controlled pharmacotherapy trials for alcohol use disorder (AUD) require an active behavioral platform to avoid putting participants at risk for untreated AUD and to better assess the effectiveness of the medication. Therapist-delivered platforms (TDP) can be costly and present a risk to study design because of the variability in therapist fidelity. Take Control is a novel computer-delivered behavioral platform developed for use in pharmacotherapy trials sponsored by the National Institute on Alcohol Abuse and Alcoholism Clinical Investigations Group (NCIG). This behavioral platform was developed with the goal of reducing trial implementation costs and limiting potential bias introduced by therapists providing TDP. This exploratory study is the first to compare Take Control with TDP on measures related to placebo response rate, medication adherence, and participant retention. Data were drawn from the placebo arms of four multisite, double-blind, randomized controlled trials (RCT) for AUD conducted by NCIG from 2007 to 2015. Data were compared from subjects receiving TDP (n=156) in two RCTs and Take Control (n=155) in another two RCTs. Placebo response rate, as represented by weekly percentage of heavy drinking days, was similar between groups. Subjects who received Take Control had a higher rate of medication adherence than those who received TDP. Subject retention was not significantly different between groups. The findings suggest that Take Control is comparable to TDP on measures of retention, medication adherence, and placebo response. Additional research is needed to evaluate Take Control directly against TDPs in a randomized trial.

Clinical trials within the US face an increasing challenge with the recruitment of quality candidates. One readily available group of subjects that have high rates of participation in clinical research are subjects who enroll in multiple trials for the purpose of generating income through study payments. Aside from issues of safety and generalizability, evidence suggests that these subjects employ methods of deception to qualify for the strict entrance criteria of some studies, including concealing information and fabricating information. Including these subjects in research poses a significant risk to the integrity of data quality and study designs. Strategies to limit enrollment of subjects whose motivation is generating income have not been systematically addressed in the literature. The present paper is intended to provide investigators with a range of strategies for developing and implementing a study protocol with protections to minimize the enrollment of subjects whose primary motivation for enrolling is to generate income. This multifaceted approach includes recommendations for advertising strategies, payment strategies, telephone screening strategies, and baseline screening strategies. The approach also includes recommendations for attending to inconsistent study data and subject motivation. Implementing these strategies may be more or less important depending upon the vulnerability of the study design to subject deception. Although these strategies may help researchers exclude subjects with a higher rate of deceptive practices, widespread adoption of subject registries would go a long way to decrease the chances of subjects enrolling in multiple studies or more than once in the same study.

The anticonvulsant topiramate not only decreases ethanol consumption in alcohol dependence (AD) but also may produce several adverse events including cognitive impairment. Zonisamide is a structurally related anticonvulsant that is a promising agent for the treatment of AD and may have greater tolerability than topiramate. This study evaluated the effects of zonisamide (400 mg/d) on alcohol consumption and its neurotoxic effects in subjects with AD. A double-blind placebo-controlled clinical trial was conducted using 2 comparator anticonvulsant drugs, topiramate (300 mg/d) and levetiracetam (2000 mg/d), which does not impair cognition. Study medications were administered for 14 weeks, including a 2-week taper period. Medication adherence was facilitated using Brief Behavioral Compliance Enhancement Treatment. The neurotoxicity of the study drugs was assessed using neuropsychological tests and the AB-Neurotoxicity Scale. Compared with placebo, both zonisamide and topiramate produced significant reductions in the drinks consumed per day, percent days drinking, and percent days heavy drinking. Only the percent days heavy drinking was significantly decreased in the levetiracetam group. The topiramate cell was the only group that had a significant increase on the mental slowing subscale of the Neurotoxicity Scale compared with placebo at study weeks 11 and 12. Topiramate and zonisamide both produced modest reductions in verbal fluency and working memory. These findings indicate that zonisamide may have efficacy in the treatment of AD, with effect sizes similar to topiramate. Both of these drugs produced similar patterns of cognitive impairment, although only the topiramate group reported significant increases in mental slowing.

AIM:As post-translational modifications of proteins may have an impact on the pathogenesis of diseases such as atherosclerosis, diabetes mellitus and chronic kidney disease (CKD), post-translational modifications are currently gaining increasing interest. In this study, a comprehensive method for analysis of these post-translational modifications is established for the clinical diagnostic routine.METHODS:Here, we analysed albumin - the most abundant plasma protein in human - isolated from patients with CKD and healthy controls by chromatographic steps and identified by MALDI mass spectrometry. Post-translational modifications of albumin were identified after digestion by analysing mass signal shifts of albumin peptides using pertinent mass databases.RESULTS:Albumin isolated from plasma of patients with CKD but not from healthy control subjects was specifically post-translationally modified by guanidinylation of lysines at positions 249, 468, 548, 565 and 588. After identification of guanidinylations as post-translational modifications of albumin isolated from patients with CKD, these modifications were quantified by mass spectrometry demonstrating a significant increase in the corresponding mass signal intensities in patients with CKD compared to healthy controls. The relative amount of guanidinylation of lysine at position 468 in patients with CKD was determined as 63 ± 32% (N = 3). Subsequently, we characterized the pathophysiological impact of the post-translational guanidinylation on the binding capacity of albumin for representative hydrophobic metabolic waste products. In vitro guanidinylation of albumin from healthy control subjects caused a decreased binding capacity of albumin in a time-dependent manner. Binding of indoxyl sulphate (protein-bound fraction) decreased from 82 ± 1% of not post-translationally modified albumin to 56 ± 1% after in vitro guanidinylation (P < 0.01), whereas the binding of tryptophan decreased from 20 to 4%. These results are in accordance with the binding of indoxyl sulphate to albumin from healthy control subjects and patients with CKD (88 ± 3 vs. 74 ± 10, P < 0.01). Thus, in vitro post-translational guanidinylation of albumin had a direct effect on the binding capacity of hydrophobic metabolites such as indoxyl sulphate and tryptophan.CONCLUSION:We used a mass spectrometry-based method for the characterization of post-translational modification and demonstrated the pathophysiological impact of a representative post-translational modification of plasma albumin. The data described in this study may help to elucidate the pathophysiological role of protein modifications.

Multiple models guide researchers' payment practices but few studies have assessed subjects' expectations for payment. Payments in excess of subjects' expectations may result in undue inducement, while payments below these expectations may be associated with exploitation. Data on subjects' payment expectations will help inform practices to avoid undue inducement and exploitation. This study examined subjects' expectations for payment for common research procedures and explored the relationship between subjects' honesty and payment expectations. One-hundred subjects who participated in two or more studies in the last year reported the minimum payment they expect for completing study procedures. They were also asked about their use of deception while screening for studies. Subjects expected $20 on average to complete the least risky and least burdensome procedure. Subjects' expectations for payment consistently increased with greater procedure risks. Subjects who denied using deception to enroll in studies refused more procedures than subjects who reported using deception. Among subjects who used deception, the rate of procedure refusal increased with procedure risks, suggesting that these subjects have some risk aversion and may act to protect themselves from undue inducement. Although subjects expect greater payments for more risky procedures, ethical considerations for limiting undue inducement may prevent researchers from meeting subjects' expectations. Subjects who use deceptive practices appear to be more risk-tolerant than subjects who deny using deception; nonetheless, these deceptive subjects also exercise some risk aversion when they refuse higher-risk procedures. These subjects may be able to protect themselves from undue inducement by refusing procedures that exceed their risk tolerance.

Objective: Patients entering treatment for alcohol problems do not have uniform treatment goals, and a pretreatment drinking goal has a significant impact on treatment outcome. The objective of this study was to understand better how an array of individual characteristics, including factors that affect treatment, are related to treatment goals before beginning alcohol treatment in the COMBINE (Combining Medications and Behavioral Interventions) Study. Method: Participants were alcohol-dependent individuals (N=1,156; 357 women) recruited at 11 outpatient academic alcoholism-treatment clinics across the United States to participate in a randomized, double-blind, placebo-controlled trial that combined behavioral intervention with acamprosate and/or naltrexone. Treatment goal was coded as controlled drinking, conditional abstinence, or total abstinence. Multinomial logistic regressions assessed whether there were significant relationships between predictor variables and pretreatment goal selection. Results: Lower levels of alcohol-related consequences, lower readiness to change, higher family income, more daily drinkers in social network, and lack of prior treatment or Alcoholics Anonymous engagement predicted choice of a controlled drinking goal over a total abstinence goal. Fewer alcohol-related consequences, lower readiness to change, and more daily drinkers in-network predicted choice of a conditional abstinence goal over a total abstinence goal. Conclusions: Higher levels of functioning, lower levels of consequences, no prior involvement in treatment and Alcoholics Anonymous, and a more drinking-saturated social environment are associated with the choice of a non-abstinence goal.

The effects of the antidepressant venlafaxine (VEN-225 mg daily) and transdiagnostic cognitive behavioral treatment (CBT) alone and in combination on alcohol intake in subjects with co-morbid alcohol use disorders (AUDs) and anxiety disorders were compared. Drinking outcomes and anxiety were assessed for 81 subjects treated for 11 weeks with one of 4 conditions: 1) VEN-CBT, 2) VEN-Progressive Muscle Relaxation therapy (PMR), 3) Placebo (PLC)-CBT and 4) a comparison group of PLC-PMR. For subjects who reported taking at least one dose of study medication, the Time×Group interaction was significant for percent days of heavy drinking and drinks consumed per day. For the measure of percent days heavy drinking, the paired comparison of PLC-CBT versus PLC-PMR group indicated that the PLC-CBT group had greater drinking reductions, whereas other groups were not superior to the comparison group. In Week 11, the proportion of subjects in the PLC-CBT group that had a 50% reduction from baseline in percent days heavy drinking was significantly greater than those in the comparison group. Of the 3 "active treatment" groups only the PLC-CBT group had significantly decreased heavy drinking when contrasted to the comparison group. This finding suggests that the transdiagnostic CBT approach of Barlow and colleagues may have value in the management of heavy drinking in individuals with co-morbid alcoholism and anxiety.

Background Subjects who enroll in multiple studies have been found to use deception at times to overcome restrictive screening criteria. Deception undermines subject safety as well as study integrity. Little is known about the extent to which experienced research subjects use deception and what type of information is concealed, withheld, or distorted.Purpose This study examined the prevalence of deception and types of deception used by subjects enrolling in multiple studies.Methods Self-report of deceptive behavior used to gain entry into clinical trials was measured among a sample of 100 subjects who had participated in at least two studies in the past year.Results Three quarters of subjects reported concealing some health information from researchers in their lifetime to avoid exclusion from enrollment in a study. Health problems were concealed by 32% of the sample, use of prescribed medications by 28%, and recreational drug use by 20% of the sample. One quarter of subjects reported exaggerating symptoms in order to qualify for a study and 14% reported pretending to have a health condition in order to qualify.Limitations Although this study finds high rates of lifetime deceptive behavior, the frequency and context of this behavior is unknown. Understanding the context and frequency of deception will inform the extent to which it jeopardizes study integrity and safety.Conclusion The use of deception threatens both participant safety and the integrity of research findings. Deception may be fueled in part by undue inducements, overly restrictive criteria for entry, and increased demand for healthy controls. Screening measures designed to detect deception among study subjects would aid in both protecting subjects and ensuring the quality of research findings.

Background Despite advances in the development of medications to treat alcohol dependence, few medications have been approved by the U.S. Food and Drug Administration. The use of certain anticonvulsant medications has demonstrated potential efficacy in treating alcohol dependence. Previous research suggests that the anticonvulsant levetiracetam may be beneficial in an alcohol-dependent population of very heavy drinkers. Methods In this double-blind, randomized, placebo-controlled clinical trial, 130 alcohol-dependent patients who reported very heavy drinking were recruited across 5 clinical sites. Patients received either levetiracetam extended-release (XR) or placebo and a Brief Behavioral Compliance Enhancement Treatment intervention. Levetiracetam XR was titrated during the first 4 weeks to 2,000 mg/d. This target dose was maintained during weeks 5 through 14 and was tapered during weeks 15 and 16. Results No significant differences were detected between the levetiracetam XR and placebo groups in either the primary outcomes (percent heavy drinking days and percent subjects with no heavy drinking days) or in other secondary drinking outcomes. Treatment groups did not differ on a number of nondrinking outcomes, including depression, anxiety, mood, and quality of life. The only difference observed was in alcohol-related consequences. The levetiracetam XR treatment group showed significantly fewer consequences than did the placebo group during the maintenance period (p = 0.02). Levetiracetam XR was well tolerated, with fatigue being the only significantly elevated adverse event, compared with placebo (53% vs. 24%, respectively; p = 0.001). Conclusions This multisite clinical trial showed no efficacy for levetiracetam XR compared with placebo in reducing alcohol consumption in heavy drinking alcohol-dependent patients.

BACKGROUND:Prior findings concerning the use of mirtazapine in the treatment of a variety of substance use disorders and its antagonistic actions at the serotonin 5-HT(2A) receptor suggest that this drug may have efficacy in the treatment of cocaine dependence in the presence of a depressive disorder.METHODS:Depressed cocaine-dependent subjects received either mirtazapine (target dose 45 mg daily) or placebo for 12 weeks. Urine concentrations of benzoylecgonine and self-report were used to assess cocaine consumption. Depression and sleep quality were evaluated using the Hamilton Depression Rating Scale (HAM-D) and the Pittsburgh Sleep Quality Index, respectively.RESULTS:Cocaine consumption during the treatment period did not differ significantly between the mirtazapine (n = 11) and placebo (n = 13) groups in this study. In week 4 sleep latency was significantly lower in the active medication than in the placebo group. Positive effects of mirtazapine treatment on early insomnia were suggested by an item analysis of the HAM-D.CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE:The results of this study suggest that mirtazapine is superior to placebo in improving sleep in patients with comorbid depression and cocaine dependence, but is not more effective than placebo in reducing cocaine use.

OBJECTIVES:The objectives of this study are to assess the tolerability and efficacy of the anticonvulsant zonisamide in an open label trial of the treatment of alcohol dependence.METHODS:In this trial, zonisamide (400-mg daily) was administered to alcohol-dependent subjects (ADS) (n = 16) over 13 weeks. The mean daily consumption of standard alcoholic drinks and performance on a verbal fluency task, the COWAT, and on a measure of attention and visuomotor speed, the DSMT were assessed, and the occurrence of adverse events was monitored weekly.RESULTS:The mean number of drinks consumed daily was significantly reduced from baseline levels during the treatment period. Performances on the COWAT and on the DSMT were not significantly reduced by zonisamide treatment. Overall, zonisamide was well tolerated by the study subjects.CONCLUSION:These results indicate that zonisamide administration may not impair verbal fluency in ADS, and are consistent with other studies that found zonisamide administration may reduce alcohol intake.
