Opioid Risk Tool, in-hospital opioid exposure, and opioid demand predict pain outcomes following traumatic injury.

Prescribed opioids are a mainstay pain treatment after traumatic injury, but a subgroup of patients may be at risk for continued opioid use. We evaluated the predictive utility of a traditional screening tool, the Opioid Risk Tool (ORT), and two other measures: average in-hospital milligram morphine equivalents (MME) per day and an assessment of opioid demand in predicting pain outcomes. Assessments of pain-related outcomes (pain intensity, interference, injury-related stress, and need for additional pain treatment) were administered at 2 weeks and 12 months post-discharge in a sample of 34 patients hospitalized for traumatic injury. Bayesian linear models were used to evaluate changes in responses over time as a function of predictors. High-risk ORT, higher MME per day, and greater opioid demand predicted less change in outcomes over time. This report provides first evidence that malleable factors of opioid and opioid demand have utility in predicting pain outcomes following traumatic injury.

Contingency management plus acceptance and commitment therapy for initial cocaine abstinence: Results of a sequential multiple assignment randomized trial (SMART).

BACKGROUND: This study tested an adaptive intervention for optimizing abstinence outcomes over phases of treatment for cocaine use disorder using a SMART design. Phase 1 assessed whether 4 weeks of contingency management (CM) improved response with the addition of Acceptance and Commitment Therapy (ACT). Phase 2 assessed pharmacological augmentation with modafinil (MOD) vs. placebo (PLA) for individuals not achieving abstinence during Phase 1. METHOD: For Phase 1 of treatment, participants (N=118) were randomly allocated to ACT+CM or Drug Counseling (DC+CM), the comparison condition. At week 4, treatment response was defined as the submission of six consecutive cocaine-negative urine drug screens (UDS). Phase 1 non-responders were re-randomized to MOD or PLA as adjunct to their initial treatment. Phase 1 responders continued receiving their initial treatment. Primary outcomes included response rate and proportion of cocaine-negative UDS for Phase 1 and 2. Analyses used Bayesian inference with 80% pre-specified as the posterior probability (PP) threshold constituting moderate evidence that an effect exists. RESULTS: Phase 1 response was higher in the ACT+CM group (24.5%) compared to the DC+CM group (17.5%; PP = 84.5%). In Phase 2, the proportion of cocaine-negative UDS among Phase 1 responders did not differ by initial treatment (PP = 61.8%) but remained higher overall compared to Phase 1 non-responders (PPs > 99%). No evidence of an effect favoring augmentation with MOD was observed. DISCUSSION: Adding ACT to CM increased abstinence initiation. Initial responders were more likely to remain abstinent compared to initial non-responders, for whom modafinil was not an effective pharmacotherapy augmentation strategy.

A meta-analysis of electrophysiological biomarkers of reward and error monitoring in substance misuse.

Substance use disorders are characterized by marked changes in reward and error processing. The primary objective of this meta-analysis was to estimate effect sizes for the reward positivity (RewP) and error-related negativity (ERN), two event-related potential indicators of outcome monitoring, in substance users compared to controls. The secondary objective was to test for moderation by demographic, substance type, and EEG experiment parameters. Final PubMed searches were performed in August 2023. Inclusion criteria were substance use disorder/dependence or validated self-report of substance misuse, RewP/ERN means available, healthy control comparison group, non-acute drug study, peer-reviewed journal, English language, and human participants. Selection bias was tested through modified Egger's regression and exploratory 3-parameter selection model tests. The RewP results (19 studies, 1641 participants) did not support an overall effect (Hedges' g = 0.07, 95% CI [-0.44, 0.58], p = .777) and nor effect of any moderators. The ERN results (20 studies, 1022 participants) indicated no significant overall effect (g = 0.41, 95%CI [-0.05, 0.88]). Subgroup analyses indicated that cocaine users had a blunted ERN compared to controls (g = 1.12, 95%CI [0.77, 1.47]). There was limited evidence for publication/small study bias. Although the results indicate a potential dissociation between substance types, this meta-analysis revealed the need for additional research on the RewP/ERN in substance using populations and for better designed experiments that adequately address research questions.

Prenatal cocaine exposure and its influence on pediatric epigenetic clocks and epigenetic scores in humans.

The investigation of the effects of prenatal cocaine exposure (PCE) on offspring has been inconsistent, with few studies investigating biological outcomes in humans. We profiled genome-wide DNA methylation (DNAm) of umbilical cord blood (UCB) from newborns with (n = 35) and without (n = 47) PCE. We used DNAm data to (1) assess pediatric epigenetic clocks at birth and (2) to estimate epigenetic scores (ES) for lifetime disorders. We generated gestational epigenetic age estimates (DNAmGA) based on Knight and Bohlin epigenetic clocks. We also investigated the association between DNAmGA and UCB serum brain-derived neurotrophic factor (BDNF) levels. Considering the large-scale DNAm data availability and existing evidence regarding PCE as a risk for health problems later in life, we generated ES for tobacco smoking, psychosis, autism, diabetes, and obesity. A gene ontology (GO) analysis on the CpGs included in the ES with group differences was performed. PCE was associated with lower DNAmGA in newborns, and this effect remained significant when controlling for potential confounders, such as blood cell type composition predicted by DNAm and obstetric data. DNAmGA was negatively correlated with BDNF levels in the serum of UCB. Higher tobacco smoking, psychosis, and diabetes ES were found in the PCE group. The GO analysis revealed GABAergic synapses as a potential pathway altered by PCE. Our findings of decelerated DNAmGA and ES for adverse phenotypes associated with PCE, suggest that the effects of gestational cocaine exposure on the epigenetic landscape of human newborns are detectable at birth.

Mental Health Clinician Practices and Perspectives on Treating Adults with Co-Occurring Posttraumatic Stress and Substance Use Disorders.

OBJECTIVE: Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) commonly co-occur and represent a complex, challenging clinical comorbidity. Meta-analytic studies and systematic reviews suggest that trauma-focused treatments are more efficacious than non-trauma focused interventions for co-occurring PTSD/SUD. However, relatively little is known about mental health clinicians' practices or preferences for treating co-occurring PTSD/SUD. The present study aimed to describe the current clinical practices of mental health clinicians who treat PTSD and/or SUD-related conditions and to assess interest in novel integrative treatments for PTSD/SUD. METHODS: Licensed mental health clinicians (N = 76; Mage = 39.59, SD = 8.14) who treat PTSD and/or SUD completed an anonymous online survey from April 2021 to July 2021. RESULTS: The majority (61.8%) of clinicians reported using integrative treatments for PTSD/SUD. The most commonly used trauma-focused treatments were 1) Cognitive Processing Therapy (CPT: 71.1%) and 2) Prolonged Exposure Therapy (PE: 68.4%) for PTSD. Approximately half (51.3%) of clinicians endorsed using Relapse Prevention (RP) for SUD. The vast majority (97.4%) of clinicians were somewhat or very interested in a new integrative CPT-RP intervention, and 94.7% of clinicians believed patients would be interested in a CPT-RP intervention. In the absence of an available evidence-based integrative treatment using CPT, 84.0% of clinicians reported modifying extant treatment protocols on their own to address PTSD and SUD concurrently. CONCLUSIONS: The findings demonstrate mental health clinician support of integrative treatments for PTSD/SUD. The most commonly used trauma-focused intervention was CPT and clinicians expressed strong interest in an integrative intervention that combines CPT and RP. Implications for future treatment development are discussed.

An opioid-minimizing multimodal pain regimen reduces opioid exposure and pain in trauma-injured patients at high risk for opioid misuse: Secondary analysis from the mast trial.

BACKGROUND: Screening to identify patients at risk for opioid misuse after trauma is recommended but not commonly used to guide perioperative opioid management interventions. The Multimodal Analgesic Strategies for Trauma trial demonstrated that an opioid-minimizing multimodal pain regimen reduced opioid exposure in a heterogeneous trauma patient population. Here, we assess the efficacy of the Multimodal Analgesic Strategies for Trauma multimodal pain regimen in a critical patient subgroup who screened at high risk for opioid misuse. METHODS: The Multimodal Analgesic Strategies for Trauma trial compared an opioid-minimizing multimodal pain regimen (oral acetaminophen, naproxen, gabapentin, lidocaine patch, as-needed opioid) against an original multimodal pain regimen (intravenous followed by oral acetaminophen, 48-hour celecoxib and pregabalin, followed by naproxen and gabapentin, scheduled tramadol, as-needed opioid), in a randomized trial conducted from April 2018 to March 2019. A total of 631 enrolled patients were classified either as low- or high-risk via the Opioid Risk Tool. Bayesian analyses evaluated the moderating influence of Opioid Risk Tool risk (high/low) on the effect of Multimodal Analgesic Strategies for Trauma multimodal pain regimen (versus original) on opioid exposure (morphine milligram equivalents/day), opioids prescribed at discharge, and pain scores. RESULTS: Multimodal Analgesic Strategies for Trauma multimodal pain regimen effectively reduced morphine milligram equivalents/day in low- and high-Opioid Risk Tool risk groups. Moderation was observed for opioids at discharge and pain scores; Multimodal Analgesic Strategies for Trauma multimodal pain regimen was effective in the high-risk group only (opioids at discharge: 63% vs 77%, relative risk = 0.86, 95% Bayesian credible interval [0.66-1.08], posterior probability (relative risk <1) = 90%; pain scores: b = 3.8, 95% Bayesian credible interval [3.2-4.4] vs b = 4.0, 95% Bayesian credible interval [3.4-4.6], posterior probability (b <0) = 87%). CONCLUSION: This study is the first to show the moderating influence of opioid misuse risk on the effectiveness of an opioid-minimizing multimodal pain regimen. The Opioid Risk Tool was useful in identifying high-risk patients for whom the Multimodal Analgesic Strategies for Trauma multimodal pain regimen is recommended for perioperative pain management.

Feasibility of Exenatide, a GLP-1R Agonist, for Treating Cocaine Use Disorder: A Case Series Study.

Cocaine use remains a serious public health problem associated with a marked increase in overdose deaths in the past decade. No medications have yet been proven to be effective for the treatment of cocaine use disorder (CUD). Among the highly promising medications have been glucagon-like peptide 1 receptor agonists (GLP-1RA) that are currently used for the treatment of type 2 diabetes mellitus and weight management. Preclinically, GLP-1RAs have been shown to attenuate cocaine self-administration, however, this has not yet been demonstrated in a human laboratory study. The GLP-1RA extended-release exenatide is given as a once-weekly injection, which may be clinically advantageous for addressing medication nonadherence among individuals with CUD. Here, we assess feasibility and safety by reporting on 3 cases of patients with CUD who received 6 weeks of exenatide 2 mg subcutaneously once-weekly in an open-label fashion, along with standard individual drug counseling. We observed excellent attendance and compliance, along with positive end-of-study satisfaction ratings. The medication was well tolerated and without unexpected or severe adverse events. Results for cocaine use and related clinical effects were more mixed, yet encouraging. Future empirical testing of exenatide for treating CUD should utilize a randomized controlled trial design and longer treatment duration.

Deficits in consummatory reward relate to severity of cocaine use.

BACKGROUND AND AIMS: Identifying modifiable neuropsychological factors associated with more severe CUD could improve CUD treatment. Impairments in processing of non-drug rewards may be one such factor. This study assessed the relationship between reward functioning and cocaine use severity using multi-modal measures of three distinct reward functions: consummatory reward (pleasure or "liking"); motivational reward ("wanting") and reward learning. METHODS: Fifty-three adults with at least moderate CUD completed self-report and behavioral measures of consummatory reward, motivational reward and reward learning, and a composite cocaine use severity measure including quantity, frequency and life impacts of cocaine use. We conducted parallel Frequentist and Bayesian multiple regressions with measures of reward functioning as predictors of cocaine use severity. RESULTS: Less self-reported ability to experience pleasure, a hypothesized measure of consummatory reward, significantly predicted greater severity after adjustment for covariates and multiple hypothesis testing, ß = 0.39, t(38) = 2.86, p = 0.007. Bayesian analyses confirmed a highly likely association between severity and ability to experience pleasure, and provided moderate evidence for associations with willingness to exert effort and reward learning. CONCLUSIONS: Our results suggest that less experience of subjective pleasure is related to greater cocaine use severity. This cross-sectional study cannot establish whether differences in consummatory reward are pre-existing, a result of CUD, or both. However, these results suggest interventions focused on increasing subjective pleasure, such as mindful "savoring", should be investigated for CUD.

Exenatide as an adjunct to nicotine patch for smoking cessation and prevention of postcessation weight gain among treatment-seeking smokers with pre-diabetes and/or overweight: study protocol for a randomised, placebo-controlled clinical trial.

INTRODUCTION: Obesity and smoking are the two leading causes of preventable death in the USA. Unfortunately, most smokers gain weight after quitting. Postcessation weight gain (PCWG) is frequently cited as one of the primary barriers to a quit attempt and a common cause of relapse. Further, excessive PCWG may contribute to the onset or progression of metabolic conditions, such as hyperglycaemia and obesity. The efficacy of the current treatments for smoking cessation is modest, and these treatments have no clinically meaningful impact on mitigating PCWG. Here, we outline a novel approach using glucagon-like peptide 1 receptor agonists (GLP-1RA), which have demonstrated efficacy in reducing both food and nicotine intake. This report describes the design of a double-blind, placebo-controlled, randomised clinical trial that evaluates the effects of the GLP-1RA exenatide as an adjunct to nicotine patches on smoking abstinence and PCWG. METHODS AND ANALYSIS: The study will be conducted at two university-affiliated research sites in Houston, Texas, the UTHealth Center for Neurobehavioral Research on Addiction and Baylor College of Medicine Michael E. DeBakey VA Medical Centre. The sample will consist of 216 treatment-seeking smokers with pre-diabetes (haemoglobin A1c of 5.7%-6.4%) and/or overweight (body mass index of 25 kg/m2 or above). Participants will be randomised (1:1) to receive subcutaneous injections of placebo or 2 mg exenatide, once weekly for 14 weeks. All participants will receive transdermal nicotine replacement therapy and brief smoking cessation counselling for 14 weeks. The primary outcomes are 4-week continuous abstinence and changes in body weight at the end of treatment. The secondary outcomes are (1) abstinence and changes in body weight at 12 weeks post end of treatment and (2) changes in neuroaffective responses to cigarette-related and food-related cues as measured by electroencephalogram. ETHICS AND DISSEMINATION: The study has been approved by the UTHealth Committee for the Protection of Human Subjects (HSC-MS-21-0639) and Baylor College of Medicine Institutional Review Board (H-50543). All participants will sign informed consent. The study results will be disseminated via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT05610800.

Types of Traumatic Experiences in Drug Overdose-Related Deaths: An Exploratory Latent Class Analysis.

Aim: Drug overdose related-deaths in the US are increasing, with over 100,000 deaths occurring in 2020, an increase of 30% from the previous year and the highest number recorded in a single year. It is widely known that experiences of trauma and substance use very often co-occur, but little is known about the role of trauma in the context of drug overdose-related deaths. Latent class analysis (LCA) was used to classify drug overdose-related deaths based on type of traumatic experiences and individual, social, and substance use characteristics. Methods: Psychological autopsy data were obtained from the University of Texas Health Science Center at Houston (UTHealth) Brain Collection. A total of 31 drug overdose-related deaths collected from January 2016 through March 2022 were included in this study. LCA was used to identify latent factors via experience of four trauma categories (illness/accidents, sexual/interpersonal violence, death/trauma to another, other situations where life was in danger). Generalized linear modeling (GLM) was used to explore differences on demographic, social, substance use, and psychiatric variables between the latent classes in separate models. Results: LCA identified 2 classes: C1 ( n =12; 39%) was characterized by higher incidence of overall trauma exposure as well as variation in trauma type; C2 ( n =19; 61%) had lower levels of overall trauma exposure with sexual/interpersonal violence as the most frequent. GLMs indicated that C1 membership was associated with higher incidence of polysubstance use, being married, and having suicidal ideation compared to C2 membership ( p s<0.05). Conclusion: Among individuals who died by drug overdose, the exploratory LCA identified two distinct subgroups that differed in type of trauma experienced and substance use pattern, the first group having more "typical" characteristics of drug overdoses cases, the other group less typical. This suggests that those at risk of drug overdose may not always exhibit high-risk characteristics.

Naltrexone plus bupropion reduces cigarette smoking in individuals with methamphetamine use disorder: A secondary analysis from the CTN ADAPT-2 trial.

INTRODUCTION: Methamphetamine (MA) use is marked by high rates of comorbid tobacco smoking, which is associated with more severe drug use and worse clinical outcomes compared to single use of either drug. Research has shown the combination of naltrexone plus oral bupropion (NTX-BUP) improves smoking cessation outcomes in non-MA-using populations. In the Accelerated Development of Additive Pharmacotherapy Treatment (ADAPT-2) study, NTX-BUP successfully reduced MA use. Our aim in this secondary data analysis was to examine changes in cigarette smoking among the subgroup of participants reporting comorbid tobacco use in the ADAPT-2 trial. METHODS: The multi-site ADAPT-2 study used a randomized, double blind, sequential parallel comparison design to evaluate treatment with extended-release injectable NTX (380 mg every 3 weeks) combined with once-daily oral extended-release BUP (450 mg/day) vs matching injectable and oral placebo in outpatients with moderate or severe MA use disorder. The study assessed smoking outcomes, based on self-reported timeline followback (TLFB) data, twice/week for 13 weeks. RESULTS: Of the 403 participants in the ADAPT-2 trial, 290 reported being current cigarette smokers (71.9 %). The study found significant differences (p's < 0.0001) for each smoking outcome indicating greater change in the proportion of nonsmoking days, number of cigarettes smoked per week, and consecutive nonsmoking days, all favoring the group receiving NTX-BUP versus placebo. CONCLUSIONS: NTX-BUP was associated with significant reductions in self-reported cigarette smoking in the context of concurrent treatment for MA use disorder. These off-target medication effects warrant prospective investigation using biochemically confirmed measures of smoking abstinence. The development of NTX-BUP as a co-addiction treatment strategy has a potential for high public health impact.

Assessing cocaine motivational value: Comparison of brain reactivity bias toward cocaine cues and cocaine demand.

The behavioral economic measure drug demand and the neural measure late positive potential (LPP) are two measures of motivational value that have been associated with drug relapse risk and treatment outcomes. Despite having overlapping themes, no studies have directly compared drug demand and LPP. Participants (N = 59) included treatment-seeking individuals with cocaine use disorder that had completed both a baseline cocaine demand task and an electroencephalogram (EEG) picture-viewing task of drug-related and pleasant picture cues. Associations between the LPP difference score amplitude (drug-pleasant) and five demand indices (Q0, essential value [EV], Omax, Pmax, and breakpoint [BP]) were evaluated via Bayesian generalized linear modeling. Positive associations (posterior probabilities ≥ 75%) were found between LPP amplitude and four demand indices (Q0, EV, Omax, BP). These results suggest that individuals who attach greater relevance to cocaine cues also exhibit greater valuation of cocaine reward. Implications for incorporating methodology from behavioral science and brain imaging are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Late positive potential as a candidate biomarker of motivational relevance in substance use: Evidence from a meta-analysis.

The objective of the current meta-analysis was to assess the effect size of the Late Positive Potential (LPP) to drug and emotional cues in substance users compared to controls. The secondary objective was to test for moderation by: age, gender, years of use, use status, and substance type. Search was performed in August 2021 using PubMed. Inclusion criteria were: substance use disorder/dependence or validated self-report, LPP means, healthy control comparison, non-acute drug study, data available, peer-reviewed journal, English, and human participants. Selection bias was tested through modified Egger's regression and exploratory 3-parameter selection model tests. Results (k = 11) indicated LPP to drug cues was larger in substance use compared to control group, with a large effect size (Hedges' g=1.66, 95%CI [0.64,2.67], p = 0.005). There were no overall differences for emotional cues. Though threats of selection bias were not severe, inclusion of more studies with larger sample sizes in future meta-analyses will allow more robust tests of publication bias and more accurate measures of effect size.

Early pain, stress, and opioid use following traumatic injury.

OBJECTIVE: Prescription opioids are an effective pain treatment strategy but can lead to long-term opioid misuse. Identifying at risk patients during hospitalization can inform the development of prevention interventions post-discharge. Using the Opioid Risk Tool (ORT) as a screening measure, this study predicted factors associated with pain and opioid use at 2 weeks post-discharge in trauma patients. DESIGN: A quality improvement prospective study design was used. SETTING: Participant recruitment took place at an inpatient Level 1 trauma center in Houston, Texas. PARTICIPANTS: Participants (n = 103) were patients admitted to the adult trauma service. Patients completed the ORT in the hospital and a survey at 2 weeks post-discharge. MAIN OUTCOME MEASURE: The survey assessed pain intensity and interference, injury-related stress, medication use, and need for additional pain treatment. Wilcoxon-Mann-Whitney U test, the Spearman rank-order correlation, and chisquare test of independence tested the ORT as a predictor of follow-up outcomes. Post hoc analyses relied on logistic and quantile regression. RESULTS: The ORT identified 15.5 percent of patients at high risk for opioid-related aberrant behavior. Survey results indicated high percentages of patients reporting moderate to severe pain (79.6 percent), pain interference (77.9 percent), taking pain pills (59.6 percent), experiencing stress (76.9 percent), and needing pain treatment (52.4 percent). The ORT predicted injury-related stress with the high-risk category having higher stress levels than low risk (Z = 2.518, p = 0.012). CONCLUSION: Risk of opioid misuse assessed in hospitalized trauma patients was associated with injury-related stress reported post-discharge. This highlights the importance of including stress assessments in follow-up appointments.

Distress tolerance: prospective associations with cognitive-behavioral therapy outcomes in adults with posttraumatic stress and substance use disorders.

74Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; Mage = 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory Serial Addition Task. The Clinician-Administered PTSD Scale for DSM-5 severity scores and percent days of primary substance use, measured via Timeline Follow-back, were used as indicators of PTSD symptoms and substance use, respectively. Covariates included treatment condition, baseline PTSD symptom severity, and baseline substance use. Lower perceived DT at baseline (DTS total score) was associated with higher PTSD symptom severity at end-of-treatment. Lower behavioral DT at baseline (MTPT duration) was associated with higher substance use at the conclusion of treatment (i.e. proportion of number of use days to total number of days between two final treatment sessions).

Comorbid alcohol use and post-traumatic stress disorders: Pharmacotherapy with aldehyde dehydrogenase 2 inhibitors versus current agents.

The increased risk of alcohol use disorder (AUD) in individuals with post-traumatic stress disorder (PTSD) is well-documented. Compared to individuals with PTSD or AUD alone, those with co-existing PTSD and AUD exhibit greater symptom severity, poorer quality of life, and poorer treatment outcomes. Although the treatment of comorbid AUD is vital for the effective management of PTSD, there is a lack of evidence on how to best treat comorbid PTSD and AUD, and currently, there are no FDA-approved treatments for the PTSD-AUD comorbidity. The objective of this manuscript is to review the evidence of a promising target for treating the AUD-PTSD comorbidity. First, we summarize the epidemiological evidence and review the completed clinical studies that have tested pharmacotherapeutic approaches for co-existing AUD and PTSD. Next, we summarize the shared pathological factors between AUD and PTSD. We conclude by providing a rationale for selectively inhibiting aldehyde dehydrogenase-2 as a potential target to treat comorbid AUD in persons with PTSD.

Nonjudgmental acceptance: Associations with substance-related cue reactivity in adults with substance use disorders and posttraumatic stress.

The present investigation examined the predictive utility of nonjudgmental acceptance, a facet of mindfulness defined as the ability to remain aware and nonevaluative about internal experience, in terms of substance-related cue reactivity among adults with substance use disorders (SUD) and posttraumatic stress (PTS) symptomatology. We hypothesized that higher nonjudgmental acceptance, indexed via self-report, would predict higher levels of self-reported control over oneself and safety 'in the moment', broadly, and lower levels of substance-related craving in response to substance script cues. Effects were expected after subtracting reactivity to neutral script cues from each outcome rating. PTS severity was included as a covariate. The sample was comprised of 53 adults (48.1% women; 75.9% African American; 74.1% with past-month PTSD) with substance dependence per DSM-IV and at least four symptoms of PTSD per DSM-5. Higher baseline nonjudgmental acceptance predicted greater safety and control in response to substance cues; no effects were found for craving. These experimental laboratory results elucidate the potential clinical utility of mindfulness-based interventions in bolstering recovery from addiction among adults with SUD/PTS by fostering safety and control in response to substance cues.

Utility of a brief assessment of opioid demand among post-discharge trauma care patients.

Opioid misuse and opioid-related death are a growing public health concern. One population of interest is recent trauma and/or surgery patients, who are at increased risk of developing an opioid use disorder (OUD). Although a variety of assessments have been developed to screen for risk of opioid misuse, each has limitations and prediction needs improvement. One promising measure is drug demand, a behavioral economic measure assessing drug consumption at different price points. In the current proposal, we assessed the utility of a brief assessment of opioid demand. Demand and various pain-related self-report measures among trauma-surgery patients (N = 103) were assessed at 4 weeks post-discharge. Opioid demand was significantly associated with self-report measures of pain and amount of morphine milligram equivalents (MME) received during the hospital stay. The current result support the utility of the opioid demand as an adjunctive and complementary measure to assess risk of opioid misuse. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
