RESUMO
OBJECTIVE: To evaluate the effects of interdisciplinary pain management on pain-related disability and opioid reduction in polymorbid pain patients with 2 or more comorbid psychiatric conditions. DESIGN: Two-arm randomized controlled trial testing a 3-week intervention with assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up. SETTING: Department of Veterans Affairs medical facility. PARTICIPANTS: 103 military veterans (N=103) with moderate (or worse) levels of pain-related disability, depression, anxiety, and/or posttraumatic stress disorder randomly assigned to usual care (n=53) and interdisciplinary pain management (n=50). All participants reported recent persistent opioid use. Trial participants had high levels of comorbid medical and mental health conditions. INTERVENTIONS: Experimental arm-a 3-week, interdisciplinary pain management program guided by a structured manual; comparison arm-usual care in a large Department of Veterans Affairs medical facility. MAIN OUTCOME MEASURES: Oswestry Disability Index (pain disability); Timeline Followback Interview and Medication Event Monitoring System (opioid use). Analysis used generalized linear mixed model with all posttreatment observations (posttreatment, 6-month follow-up, 12-month follow-up) entered simultaneously to create a single posttreatment effect. RESULTS: Veterans with polymorbid pain randomized to the interdisciplinary pain program reported significantly greater decreases in pain-related disability compared to veterans randomized to treatment as usual (TAU) at posttreatment, 6-month, and 12-month follow-up. Aggregated mean pain disability scores (ie, a summary effect of all posttreatment observations) for the interdisciplinary pain program were -9.1 (95% CI: -14.4, -3.7, P=.001) points lower than TAU. There was no difference between groups in the proportion of participants who resumed opioid use during trial participation (32% in both arms). CONCLUSION: These findings offer the first evidence of short- and long-term interdisciplinary pain management efficacy in polymorbid pain patients, but more work is needed to examine how to effectively decrease opioid use in this population.

Prescription opioid misuse is a rising epidemic in the U.S., and people living with HIV are at increased risk. We assessed the association between prescription opioid use and virologic failure in HIV+ patients in the South Texas HIV Cohort. We found prescription opioid use was significantly associated with virologic failure, after adjustment for age, race, gender, insurance status, years living with HIV, reported HIV risk factor, chronic hepatitis C virus infection, current substance abuse, and care engagement. These findings suggest that opioid analgesic use may have negative consequences beyond misuse in people living with HIV.

Opioid misuse is a growing epidemic among the civilian and military communities. Five hundred prospective, anonymous surveys were collected in the emergency department waiting room of a military tertiary care hospital over 3 weeks. Demographics, medical and military characteristics were investigated for association with opioid use. Univariate logistic models were used to characterize the probability of misuse in relation to the demographic, medical, and military-specific variables. Traumatic brain injury (TBI) and posttraumatic stress disorder were investigated within different age cohorts with adjustment for deployment. The opioid misuse rate disclosed by the subject was 31%. Subjects with TBI were less likely to misuse opioids. We found a trend among younger cohorts to have a higher likelihood for misusing opioids when diagnosed with TBI or posttraumatic stress disorder with history of deployment in the past 5 years. The most common form of misuse was using a previously prescribed medication for a new pain. Traumatic brain injury and/or enrollment in post-deployment recovery programs maybe protective against opioid misuse. Chronic opioid use among young soldiers maybe viewed as a weakness that could influence opioid misuse. Younger cohorts of active duty service members could be at higher risk for misuse. Efforts to enhance close monitoring of misuse should address these at-risk populations.

BACKGROUND: Increasingly, new HIV infections among people who use drugs are attributed to sexual risk behavior. However, HIV prevention research targeting persons with opioid dependence continues to focus on drug injection practices. Moreover, despite the rising prevalence of prescription opioid dependence in the United States, little is known about HIV risk in this population. METHODS: This study examined the prevalence of sexual risk behavior among patients with opioid dependence who primarily use prescription opioids for non-medical purposes. As part of a multi-site clinical trial, participants (N = 653) completed a baseline assessment that included the Risk Behavior Survey. RESULTS: In the past month, 74% were sexually active. Of these, most had opposite sex partners (97.3%) and vaginal intercourse (97.1%); anal intercourse was uncommon (3.1%). The majority reported unprotected intercourse (76.5%), but few had multiple partners (11.3%). Unprotected intercourse was associated with history of other substance dependence (adjusted odds ratio [AOR] = 1.73), and having multiple partners was associated with concurrent cocaine use (AOR = 2.54). Injection drug use in the past month was rare (2.5%). CONCLUSIONS: While the majority of sexually active participants engaged in unprotected intercourse, the proportion with multiple sex partners was low relative to other samples of persons who use illicit drugs. Among persons with non-medical prescription opioid dependence, those who concurrently use other substances may be at elevated risk for HIV infection. Comprehensive assessment of substance abuse history among individuals dependent upon prescription opioids is critical for identifying patients who may require additional clinical interventions to reduce HIV sexual risk behavior.

BACKGROUND: Given the growing prevalence of prescription opioid dependence and the considerable rates of additional psychopathology in drug dependence, we examined the association between the presence of a co-occurring Axis I psychiatric disorder and sociodemographic and clinical characteristics in this secondary analysis of patients entering a treatment study for dependence on prescription opioids. Treatment outcomes were also compared. METHODS: Patients dependent on prescription opioids participated in a multi-site, two-phase, randomized, controlled trial to assess different lengths of buprenorphine-naloxone pharmacotherapy and different intensities of counseling (Clinicaltrials.gov identifier: NCT00316277). Among the 653 participants entering the first phase of the trial, 360 entered the second phase, receiving 12 weeks of buprenorphine-naloxone treatment; they are reported here. Half of those participants (180/360) had a current co-occurring psychiatric disorder in addition to substance dependence. RESULTS: Sociodemographic characteristics were similar overall between those with and without a co-occurring psychiatric disorder, but women were 1.6 times more likely than men to have a co-occurring disorder. On several clinical indicators at baseline, participants with a co-occurring disorder had greater impairment. However, they had better opioid use outcomes at the conclusion of 12 weeks of buprenorphine-naloxone stabilization than did participants without a co-occurring disorder. CONCLUSIONS: Prescription opioid-dependent patients with a co-occurring psychiatric disorder had a better response to buprenorphine-naloxone treatment despite demonstrating greater impairment at baseline. Additional research is needed to determine the mechanism of this finding and to adapt treatments to address this population.

BACKGROUND: Self-management of opioid use disorder (OUD) is an important component of treatment. Many patients receiving opioid agonist treatment in methadone maintenance treatment settings benefit from counseling treatments to help them improve their recovery skills but have insufficient access to these treatments between clinic appointments. In addition, many addiction medicine clinicians treating patients with OUD in a general medical clinic setting do not have consistent access to counseling referrals for their patients. This can lead to decreases in both treatment retention and overall progress in the patient's recovery from substance misuse. Digital apps may help to bridge this gap by coaching, supporting, and reinforcing behavioral change that is initiated and directed by their psychosocial and medical providers. OBJECTIVE: This study aimed to conduct an acceptability, usability, and utility pilot study of the KIOS app to address these clinical needs. METHODS: We developed a unique, patient-centered computational software system (KIOS; Biomedical Development Corporation) to assist in managing OUD in an outpatient, methadone maintenance clinic setting. KIOS tracks interacting self-reported symptoms (craving, depressed mood, anxiety, irritability, pain, agitation or restlessness, difficulty sleeping, absenteeism, difficulty with usual activities, and conflicts with others) to determine changes in both the trajectory and severity of symptom patterns over time. KIOS then applies a proprietary algorithm to assess the individual's patterns of symptom interaction in accordance with models previously established by OUD experts. After this analysis, KIOS provides specific behavioral advice addressing the individual's changing trajectory of symptoms to help the person self-manage their symptoms. The KIOS software also provides analytics on the self-reported data that can be used by patients, clinicians, and researchers to track outcomes. RESULTS: In a 4-week acceptability, usability (mean System Usability Scale-Modified score 89.5, SD 9.2, maximum of 10.0), and utility (mean KIOS utility questionnaire score 6.32, SD 0.25, maximum of 7.0) pilot study of 15 methadone-maintained participants with OUD, user experience, usability, and software-generated advice received high and positive assessment scores. The KIOS clinical variables closely correlated with craving self-report measures. Therefore, managing these variables with advice generated by the KIOS software could have an impact on craving and ultimately substance use. CONCLUSIONS: KIOS tracks key clinical variables and generates advice specifically relevant to the patient's current and changing clinical state. Patients in this pilot study assigned high positive values to the KIOS user experience, ease of use, and the appropriateness, relevance, and usefulness of the specific behavioral guidance they received to match their evolving experiences. KIOS may therefore be useful to augment in-person treatment of opioid agonist patients and help fill treatment gaps that currently exist in the continuum of care. A National Institute on Drug Abuse-funded randomized controlled trial of KIOS to augment in-person treatment of patients with OUD is currently being conducted.
RESUMO
Background: There has been a significant increase in methamphetamine use and methamphetamine use disorder (Meth UD) in the United States, with evolving racial and ethnic differences. Objectives: This secondary analysis explored racial and ethnic differences in baseline sociodemographic and clinical characteristics as well as treatment effects on a measure of substance use recovery, depression symptoms, and methamphetamine craving among participants in a pharmacotherapy trial for Meth UD. Methods: The ADAPT-2 trial (ClinicalTrials.gov number, NCT03078075; N=403; 69% male) was a multisite, 12-week randomized, double-blind, trial that employed a two-stage sequential parallel design to evaluate the efficacy of combination naltrexone (NTX) and oral bupropion (BUP) vs. placebo for Meth UD. Treatment effect was calculated as the weighted mean change in outcomes in the NTX-BUP minus placebo group across the two stages of treatment. Results: Of the 403 participants in the ADAPT-2 trial, the majority (65%) reported non-Hispanic White, while 14%, 11% and 10% reported Hispanic, non-Hispanic Black, and non-Hispanic other racial and ethnic categories respectively. At baseline non-Hispanic Black participants reported less severe indicators of methamphetamine use than non-Hispanic White. Treatment effects for recovery, depression symptoms and methamphetamine cravings did not significantly differ by race and ethnicity. Conclusions: Although we found racial and ethnic differences at baseline, our findings did not show racial and ethnic differences in treatment effects of NTX-BUP on recovery, depression symptoms and methamphetamine cravings. However, our findings also highlight the need to expand representation of racial and ethnic minority groups in future trials.
RESUMO
BACKGROUND AND AIMS: Socio-cultural (gender) and biological (sex)-based differences contribute to psychostimulant susceptibility, potentially affecting treatment responsiveness among women with methamphetamine use disorder (MUD). The aims were to measure (i) how women with MUD independently and compared with men respond to treatment versus placebo and (ii) among women, how the hormonal method of contraception (HMC) affects treatment responsiveness. DESIGN: This was a secondary analysis of ADAPT-2, a randomized, double-blind, placebo-controlled, multicenter, two-stage sequential parallel comparison design trial. SETTING: United States. PARTICIPANTS: This study comprised 126 women (403 total participants); average age = 40.1 years (standard deviation = 9.6) with moderate to severe MUD. INTERVENTIONS: Interventions were combination intramuscular naltrexone (380 mg/3 weeks) and oral bupropion (450 mg daily) versus placebo. MEASUREMENTS: Treatment response was measured using a minimum of three of four negative methamphetamine urine drug tests during the last 2 weeks of each stage; treatment effect was the difference between weighted treatment responses of each stage. FINDINGS: At baseline, women used methamphetamine intravenously fewer days than men [15.4 versus 23.1% days, P = 0.050, difference = -7.7, 95% confidence interval (CI) = -15.0 to -0.3] and more women than men had anxiety (59.5 versus 47.6%, P = 0.027, difference = 11.9%, 95% CI = 1.5 to 22.3%). Of 113 (89.7%) women capable of pregnancy, 31 (27.4%) used HMC. In Stage 1 29% and Stage 2 5.6% of women on treatment had a response compared with 3.2% and 0% on placebo, respectively. A treatment effect was found independently for females and males (P < 0.001); with no between-gender treatment effect (0.144 females versus 0.100 males; P = 0.363, difference = 0.044, 95% CI = -0.050 to 0.137). Treatment effect did not differ by HMC use (0.156 HMC versus 0.128 none; P = 0.769, difference = 0.028, 95% CI -0.157 to 0.212). CONCLUSIONS: Women with methamphetamine use disorder receiving combined intramuscular naltrexone and oral bupropion treatment achieve greater treatment response than placebo. Treatment effect does not differ by HMC.

OBJECTIVES: To address the critical need for opioid use disorder (OUD) treatment by rapidly planning and implementing a statewide DEA X-waiver training initiative expanding office-based OUD treatment in Texas by: (1) facilitating access to buprenorphine waiver trainings to targeted regions and health care providers across the state; and (2) supporting completion of DEA X-waiver requirements. METHODS: We used a transdisciplinary and theory-driven approach to adapt and rapidly scale up an existing, previously successful DEA X-waiver initiative. Pre-implementation activities included a literature review to identify OUD treatment barriers and demographic analyses to identify high-need areas of the state. We used geospatial mapping methods to identify regions with highest point prevalence of opioid-overdose mortality and low access to a buprenorphine provider. The study team used the Replicating Effective Programs (REP) framework developed by the Centers for Disease Control and Prevention to support implementation of evidence-based practices. RESULTS: In six months, we trained 451 waiver eligible providers, 133 (29%) of whom received waivers by 6 months post-training. Of the 163 (36.1%) providers who completed the post-waiver evaluation, 97% reported that they were satisfied or very satisfied with the training. Our initiative delivered high quality education to providers and increased the number of waiver trainers in Texas from eight to thirteen. CONCLUSIONS: Despite recent changes to the DEA X-waiver process, barriers to treating OUD with buprenorphine remain. Lack of education and experience treating substance use disorders remains a significant factor in limiting clinician comfort in prescribing buprenorphine. The research team successfully adapted a Texas-wide initiative to increase the number of office-based providers eligible to prescribe buprenorphine for OUD from an existing single-site initiative. Attentiveness to barriers pre-implementation and to adaptations during implementation enabled moderate impact across a large network in a short time and facilitated program sustainment.

Background and Objectives: Patients taking opioids are at risk of developing dependence and possibly abuse. Given the role of the mesolimbic dopamine system in opioid reward, blocking dopamine D2 receptors should limit the abuse liability of opioid analgesics. This pilot study evaluates the analgesic efficacy of oxycodone combined with an atypical antipsychotic (dopamine D2 receptor antagonist). Methods: A randomized, double-blind, within-subjects, controlled trial in healthy volunteers was conducted at UT Health SA Pain Clinic. Fifteen volunteers with previous medical exposure to opioids were enrolled. Risperidone (2 mg) or ziprasidone (80 mg) in combination with oxycodone (5, 10, 15 mg) was administered. Pain intensity using the cold pressor test, Current Opioid Misuse Measure (COMM), Addiction Research Center Inventory (ARCI, opioid subscale), Drug likability with drug effects questionnaire (DEQ) were assessed. Results: Oxycodone produced dose dependent increases in thermal analgesia on the cold pressor test that was significant at 10 and 15 mg (t = 3.087, P = 0.017). The combination did not significantly alter thermal analgesia. There was no significant effect of the combination on the ARCI or the POMS. Discussion and Conclusion: The combination of an atypical antipsychotic with oxycodone does not alter analgesic response or increase the incidence of adverse effects when compared to oxycodone alone. Such information is critical for the development of drug combinations for the treatment of pain and provide the foundation for future studies of abuse potential in drug users. Scientific Significance: This intervention in chronic pain patients is unique because it utilizes FDA approved drugs in combination to reduce abuse liability. The first step, and aim of this study, is to confirm the drug combination does not interfere with analgesic efficacy. The next step is to examine the combination in recreational drug users to assess the potential to block the euphoric effects of oxycodone. Ultimately, if this combination is effective, this approach could be beneficial in management of chronic pain.
RESUMO
Importance: As opioid-related deaths continue to climb, methods to reduce barriers to prescribing buprenorphine for individuals with opioid use disorder (OUD) are needed. Recent conversations by state and federal authorities targeting low-threshold buprenorphine aim to reduce some barriers to prescribing buprenorphine; however, what remains unclear is whether removal of the requirement to obtain a waiver for prescribing buprenorphine through the Drug Addiction Treatment Act of 2000 (an X-waiver) will be enough to increase access to buprenorphine. Objective: To assess barriers and facilitators of obtaining an X-waiver and prescribing buprenorphine. Design, Setting, and Participants: This mixed-method survey study was conducted between September and December 2020; 607 office-based Texas clinicians were surveyed after they attended a buprenorphine X-waiver training course. All attendees between March 2, 2019, and February 28, 2020, were eligible to receive this survey; 126 responses were received (20% response rate: 81 physicians, 37 nurse practitioners, and 8 physician assistants). Data analysis was performed October 2021. Main Outcomes and Measures: Surveys measured the extent to which clinicians experienced 9 previously identified barriers during the waiver process and in prescribing buprenorphine. The survey included open-ended items assessing facilitating factors to obtaining a waiver and to prescribing buprenorphine for OUD. The barriers were analyzed using χ2 tests of homogeneity. Qualitative data were analyzed using a constant comparative method. Results: Among 126 clinicians who responded, 61 (48.4%) had received an X-waiver; of these waivered clinicians, 22 (36%) were prescribing buprenorphine and 39 (64%) were not. "Complexity of X-waiver process," "Perceived lack of professional support and referral network," and "Getting started" were significantly different barriers among waivered and nonwaivered clinicians. Significant differences in barriers experienced between prescribers and nonprescribers were "Getting started" and "Accessing reimbursement for treatment." The most frequently mentioned facilitators involved changes to the waiver training and the need for networks connecting experienced clinicians with those in the initial stages of readiness for prescribing buprenorphine for OUD. Conclusions and Relevance: This survey study's results contribute new understanding of facilitators to obtaining the X-waiver and to prescribing buprenorphine. Furthermore, these findings suggest that to increase access to compassionate evidence-based treatment for OUD, clinicians need ongoing support and mentorship from experienced and knowledgeable clinicians. Interventions aimed at improving access to buprenorphine should focus on facilitating such networks to increase the number of clinicians who obtain an X-waiver and prescribe buprenorphine for OUD.

BACKGROUND: Given the relatively high rates of suicidal ideation and attempt among people with chronic pain, there is a need to understand the underlying factors to target suicide prevention efforts. To date, no study has examined the association between pain phenotypes and suicide related behaviors among those with mild traumatic brain injuries. OBJECTIVE: To determine if pain phenotypes were independently associated with suicidal ideation / attempt or if comorbidities within the pain phenotypes account for the association between pain phenotypes and suicide related behaviors. METHODS: This is a longitudinal retrospective cohort study of suicide ideation/attempts among pain phenotypes previously derived using general mixture latent variable models of the joint distribution of repeated measures of pain scores and pain medications/treatment. We used national VA inpatient, outpatient, and pharmacy data files for Post-9/11 Veterans with mild traumatic injury who entered VA care between fiscal years (FY) 2007 and 2009. We considered a counterfactual causal modeling framework to assess the extent that the pain phenotypes during years 1-5 of VA care were predictive of suicide ideation/attempt during years 6-8 of VA care conditioned on covariates being balanced between pain phenotypes. RESULTS: Without adjustment, pain phenotypes were significant predictors of suicide related behaviors. When we used propensity scores to balance the comorbidities present in the pain phenotypes, the pain phenotypes were no longer significantly associated with suicide related behaviors. CONCLUSION: These findings suggest that suicide ideation/attempt is associated with pain trajectories primarily through latent multimorbidity. Therefore, it is critical to identify and manage comorbidities (e.g., depression, post-traumatic stress disorder) to prevent tragic outcomes associated with suicide related behaviors throughout the course of chronic pain and mild traumatic brain injury management.

BACKGROUND: While clinical interventions used to support the recovery process of U.S. adults are well understood, community-based solutions such as peer-based recovery support services delivered by a recovery community organization are not. METHODS: Previously collected administrative data of 3459 participants at 20 recovery community organizations in the U.S. were analyzed using a paired samples t-test to examine intake and current recovery capital differences, and multiple linear regression models to examine the association between peer-based recovery support engagement on changes in recovery capital. RESULTS: Participants were mostly male (52.1%), non-Hispanic (80.2%), White (75.5%), with an average age of 39.38 years (SD = 12.57). Participants' average engagement was 130.68 days (SD = 166.6) with a total of 4290 engagement sessions (M = 4.75, SD = 4.74) and 8913 brief check-ins (M = 5.0, SD = 5.03) facilitated. Reported health events were 0.09 recurrences of substance use (SD = 0.61) and 0.02 emergency room visits (SD = 0.26) on average. Paired sample t-test results showed a statistically significant increase in recovery capital of 1.33 points (95% CI: 0.97-1.69). Multiple linear regression models for predicting improvements in recovery capital (adjusted r2 = 0.61) found number of follow-up engagements and completed recovery plan goals were statistically significant predictors. CONCLUSIONS: Peer-based recovery support services delivered by recovery community organizations assist in significantly improving individual recovery capital, as well as helping to facilitate involvement with an array of recovery support services that may contribute to other functional social determinant domain improvements and lower negative health events.

Most treatment studies of opioid-dependent populations have focused predominantly on heroin users, despite a recent increase in those dependent upon prescription opioids. A key methodological challenge involved in studying the latter group involves defining the population. Specifically, researchers must decide whether to include (1) concurrent heroin users and (2) individuals with pain. The multi-site Prescription Opioid Addiction Treatment Study is examining treatments for this population. This paper describes various inclusion criteria considered by the study team related to heroin use and pain. The goal was to recruit a distinct but generalizable population of individuals dependent upon prescription opioids. (Am J Addict 2010;00:1-6).

BACKGROUND: We explored pain, psychological flexibility, and continued substance use among 100 adults treated with methadone for opioid use disorder (OUD). All participants had co-occurring chronic pain. METHODS: Participants recruited from a community treatment center between 2009 and 2010 completed an interviewer-facilitated assessment. Chronic pain severity and interference, psychological flexibility (mindfulness, acceptance, values success), past 30-day substance use, and demographics were reported. We modeled a zero-inflated negative binomial regression to examine 1) the probability that an individual does not use illicit substances and 2) illicit substance use frequency among those expected to use. Pain severity and mindfulness were included as predictors in the logit (zero inflated) model. Pain interference, acceptance, and values success were included as predictors in the negative binomial (count) model. We controlled for age and gender in both models. RESULTS: Participants were predominantly (84%) Hispanic, and 64% used an illicit substance least once in the past 30 days. Greater degree of mindfulness significantly predicted the probability that an individual does not continue to use illicit substances (OR = 1.59, p < 0.05). Lower degree of values success significantly predicted greater illicit substance use frequency among those likely to use (IRR = 0.72, p < 0.01). No other variables were associated with continued substance use. CONCLUSIONS: Findings suggest psychological flexibility is associated with continued substance use in this predominantly Hispanic sample of adults treated for OUD with co-occurring chronic pain. Study findings may have implications for how to address the treatment needs of this complex population.

Pain is a pervasive problem that affects nearly half of the U.S. Veterans deployed in support of the Global War on Terror (Post-9/11 Veterans) and over half of the Post-9/11 Veterans with diagnosed traumatic brain injury (TBI). The goal of the current study was to identify pain phenotypes based on distinct longitudinal patterns of pain scores in light of pain treatment among Post-9/11 Veterans over 5 years of care using latent growth mixture analysis stratified by TBI status. Five pain phenotypes emerged: 1) simple low impact stable pain, 2) complex low impact stable pain, 3) complex low impact worsening pain, 4) complex moderate impact worsening pain, and 5) complex high impact stable pain. Baseline pain scores and slopes were significantly higher in Veterans with mild TBI for some phenotypes. The mild TBI cohort was younger, had more men, more whites, less blacks, less education, more unmarried, more Marines and Army, more active duty in comparison to the no TBI cohort. Distinct trajectories in pain treatment were apparent among the pain intensity subgroups. PERSPECTIVE: The complexity of pain in patients with mTBI is categorically different than those with no TBI. Pain in patients with mTBI is heterogeneous with distinct phenotypes which may explain poor outcomes in this group. Identification of the individual differences may have a significant impact on the success of interventions.

The comorbidity of chronic pain and opioid addiction is a serious problem that has been growing with the practice of prescribing opioids for chronic pain. Neuroimaging research has shown that chronic pain and opioid dependence both affect brain structure and function, but this is the first study to evaluate the neurophysiological alterations in patients with comorbid chronic pain and addiction. Eighteen participants with chronic low back pain and opioid addiction were compared with eighteen age- and sex-matched healthy individuals in a pain-induction fMRI task. Unified structural equation modeling (SEM) with Lagrange multiplier (LM) testing yielded a network model of pain processing for patient and control groups based on 19 a priori defined regions. Tests of differences between groups on specific regression parameters were determined on a path-by-path basis using z-tests corrected for the number of comparisons. Patients with the chronic pain and addiction comorbidity had increased connection strengths; many of these connections were interhemispheric and spanned regions involved in sensory, affective, and cognitive processes. The affected regions included those that are commonly altered in chronic pain or addiction alone, indicating that this comorbidity manifests with neurological symptoms of both disorders. Understanding the neural mechanisms involved in the comorbidity is crucial to finding a comprehensive treatment, rather than treating the symptoms individually.
RESUMO
OBJECTIVE: This study explored the relationship between substance use disorder risk and self-compassion and posits a model for how the two are related through the mitigation of suffering. METHOD: Study participants were recruited using social media to complete an online survey that included a basic socio-demographic survey and two validated instruments, the Self-Compassion Survey and the National Institute on Drug Abuse (NIDA) Alcohol Smoking and Substance Involvement Screening Test (ASSIST), which screens for substance use disorder (SUD) risk. Established cut scores for ASSIST were used to divide participants into low, moderate and high-risk groups. RESULTS: Participants (n=477) were 31 years old on average, almost evenly split by gender, mostly non-Hispanic white, slightly more likely to be single and to hold an Associate's degree or higher. Overall, 89% of participants reported using drugs and/or alcohol in their lifetime. SUD risk was distributed between low risk (52%), moderate risk (37%) and a smaller percentage of high risk (11%). Self-compassion was inversely related to SUD risk. The low risk group had a higher mean self-compassion score (M=2.86, SD=0.75) than the people who were high risk (M=2.25, SD=0.61) (t(298)=5.58 p<0.0001). Bivariate Pearson correlations showed strong associations between high risk and all self-compassion subscales, as well as low risk and five of the subscales. CONCLUSIONS: This study suggests SUD risk has an inverse relationship to self-compassion. Raising self-compassion may be a useful addition to substance use disorder prevention and treatment interventions.

Over the past few decades, the rise of multiple chronic conditions has become a major concern for clinicians. However, it is still not known precisely how multiple chronic conditions emerge among patients. We propose an unsupervised multi-level temporal Bayesian network to provide a compact representation of the relationship among emergence of multiple chronic conditions and patient level risk factors over time. To improve the efficiency of the learning process, we use an extension of maximum weight spanning tree algorithm and greedy search algorithm to study the structure of the proposed network in three stages, starting with learning the inter-relationship of comorbidities within each year, followed by learning the intra-relationship of comorbidity emergence between consecutive years, and finally learning the hierarchical relationship of comorbidities and patient level risk factors. We also use a longest path algorithm to identify the most likely sequence of comorbidities emerging from and/or leading to specific chronic conditions. Using a de-identified dataset of more than 250,000 patients receiving care from the U.S. Department of Veterans Affairs for a period of five years, we compare the performance of the proposed unsupervised Bayesian network in comparison with those of Bayesian networks developed based on supervised and semi-supervised learning approaches, as well as multivariate probit regression, multinomial logistic regression, and latent regression Markov mixture clustering focusing on traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), depression (Depr), substance abuse (SuAb), and back pain (BaPa). Our findings show that the unsupervised approach has noticeably accurate predictive performance that is comparable to the best performing semi-supervised and the second-best performing supervised approaches. These findings also revealed that the unsupervised approach has improved performance over multivariate probit regression, multinomial logistic regression, and latent regression Markov mixture clustering.

Introduction: Between 2001 and 2009, opioid analgesic prescriptions in the Military Health System quadrupled to 3.8 million. The sheer quantity of opioid analgesics available sets the stage for issues related to misuse, abuse, and diversion. To address this issue, the Department of Defense implemented several directives and clinical guidelines to improve access to appropriate pain care and safe opioid prescribing. Unfortunately, little has been done to characterize changing patterns of opioid use in active duty service members (ADSM), so little is known about how combat operations and military health care policy may have influenced this significant problem. We examined changes in opioid use for ADSM between 2006 and 2014, compared trends with the civilian population, and explored the potential role of military-specific factors in changes in opioid use in the Military Health System. Materials and Methods: After obtaining Institutional Review Board approval, administrative prescription records (Pharmacy Data Transaction Records) for non-deployed ADSM were used to determine the number of opioid prescriptions dispensed each year and the proportion of ADSM who received at least one prescription per month between 2006 and 2014. Based on the observation and the literature, we identified December 2011 as the demarcation point (the optimal point to identify the downturn in opioid use) and used it to compare opioid use trends before and after. We used an autoregressive forecast model to verify changes in opioid use patterns before and after 2011. Several interrupted time series models examined whether military system-level factors were associated with changes in opioid use. Results: Between 2006 and 2014, 1,516,979 ADSM filled 7,119,945 opioid prescriptions, either in military treatment facilities or purchased through TRICARE. Both active duty and civilian populations showed signs of decreasing use after 2011, but this change was much more pronounced among ADSM. The forecast model showed a significant difference after 2011 between the projected and actual proportion of ADSM filling an opioid prescription, confirming 2011 as a point of divergence in opioid use. Interrupted time series models showed that the deflection point was associated with significant decreases. A significant increase of 0.261% in opioid prescriptions was seen for every 1,000 wounded in action service members in a given month. Troops returning from Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn did not appear to influence the rates of use. Even after accounting for returning troops from Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn and wounded in action counts, the deflection point was associated with a lower proportion of ADSM who filled an opioid prescription, leading to a decrease of 1.61% by the end of the observation period (December 2014). Conclusion: After December 2011, opioid use patterns significantly decreased in both civilian and ADSM populations, but more so in the military population. Many factors, such as numbers of those wounded in action and the structural organization of the Military Health System, may have caused the decline, although more than likely the decrease was influenced by many factors inside and outside of the military, including policy directives and cultural changes.
