Abstract
The prefrontal cortex (PFC) has justifiably become a significant focus of chronic pain research. Collectively, decades of rodent and human research have provided strong rationale for studying the dysfunction of the PFC as a contributing factor in the development and persistence of chronic pain and as a key supraspinal mechanism for pain-induced comorbidities such as anxiety, depression, and cognitive decline. Chronic pain alters the structure, chemistry, and connectivity of PFC in both humans and rodents. In this review, we broadly summarize the complexities of reported changes within both rodent and human PFC caused by pain and offer insight into potential pharmacological and nonpharmacological approaches for targeting PFC to treat chronic pain and pain-associated comorbidities. SIGNIFICANCE STATEMENT: Chronic pain is a significant unresolved medical problem causing detrimental changes to physiological, psychological, and behavioral aspects of life. Drawbacks of currently approved pain therapeutics include incomplete efficacy and potential for abuse producing a critical need for novel approaches to treat pain and comorbid disorders. This review provides insight into how manipulation of prefrontal cortex circuits could address this unmet need of more efficacious and safer pain therapeutics.

Abstract
OBJECTIVE Depressive symptoms are prevalent among knee osteoarthritis (KOA) patients and may lead to additional medical costs. We compared medical costs in Medicare Current Beneficiary Survey (MCBS) respondents with KOA with and without self-reported depressive symptoms. METHODS We identified a KOA cohort using ICD-9/10 diagnostic codes in both Part A and Part B claims among community-dwelling MCBS respondents from 2003 to 2019. We determined the presence of depressive symptoms using self-reported data on sadness or anhedonia. We considered three groups: 1) without depressive symptoms, 2) with depressive symptoms, no billable services, and 3) with depressive symptoms and billable services. We used a generalized linear model with log-transformed outcomes to compare annual total direct medical costs among the three groups, adjusting for age, gender, race, history of fall, Total Joint Replacement, comorbidities, and calendar year. RESULTS The analysis included 4118 MCBS respondents with KOA. Of them, 27% had self-reported depressive symptoms, and 6% reported depressive symptoms and received depression-related billable services. The adjusted mean direct medical costs were $8598/year for those without depressive symptoms, $9239/year for those who reported depressive symptoms and received no billable services, and $14,229/year for those who reported depressive symptoms and received billable services. CONCLUSION While over one quarter of Medicare beneficiaries with KOA self-reported depressive symptoms, only 6% received billable medical services. The presence of depressive symptoms led to higher direct medical costs, even among those who did not receive depression-related billable services.

Abstract
Ketamine is a restricted and regulated medication in Australia and New Zealand, which has implications when considering treatment for patients with treatment-resistant depression and a history of illicit drug use, abuse or dependence. Regulations governing prescription of ketamine for treatment-resistant depression vary between jurisdictions in Australia and New Zealand, though most restrict use in those with drug dependence. There is substantial variation in definitions of drug dependence used in each jurisdiction, and between the legal and clinical definitions, with the latter specified in the current International Classification of Diseases, Eleventh Revision and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. This paper reviews the literature assessing the risk of ketamine misuse and dependence in patients with a history of illicit drug use, abuse or dependence and presents recommendations for psychiatrists who prescribe ketamine in such patients with treatment-resistant depression.

Garland EL, Jinpa T. Mindfulness-induced self-transcendence promotes universal love with consequent effects on opioid misuse. Behav Res Ther 2024; 175:104494.

Abstract
In addition to its health benefits, mindfulness has been theorized in classical contemplative frameworks to elicit self-transcendent experiences as a means of promoting universal love and compassion. Increasing feelings of love may be especially clinically relevant for the treatment of opioid misuse, in that addictive use of opioids dysregulates neurobiological processes implicated in the experience of love. Here we tested these hypotheses in a secondary analysis (n = 187) of data from a randomized clinical trial of Mindfulness-Oriented Recovery Enhancement (MORE) versus supportive psychotherapy for comorbid opioid misuse and chronic pain. At pre- and post-treatment, participants completed a measure of state self-transcendence immediately following a laboratory-based mindfulness task. Through 9-month follow-up, we assessed changes in universal love and opioid misuse. Participants also completed ecological momentary assessments of opioid craving during the 8-week study interventions and for the following month. Compared to supportive psychotherapy, participants in MORE reported significantly greater increases in mindfulness-induced self-transcendence, which mediated the effect of MORE on increased feelings of universal love. In turn, increases in universal love significantly predicted decreased opioid craving and lower odds opioid misuse through 1- and 9-month follow-ups, respectively. Findings suggest mindfulness-induced self-transcendence may promote feelings of universal love, with possible downstream benefits on reducing addictive behavior.

Abstract
Chronic pain is commonly treated with long-term opioids, but the neuropsychological outcomes associated with stable long-duration opioid use remain unclear. Here, we contrasted the psychological profiles, brain activity, and brain structure of 70 chronic back pain patients on opioids (CBP+O, average opioid exposure 6.2 years) with 70 patients managing their pain without opioids. CBP+O exhibited moderately worse psychological profiles and small differences in brain morphology. However, CBP+O had starkly different spontaneous brain activity, dominated by increased mesocorticolimbic and decreased dorsolateral-prefrontal activity, even after controlling for pain intensity and duration. These differences strongly reflected cortical opioid and serotonin receptor densities and mapped to two antagonistic resting-state circuits. The circuits' dynamics were explained by mesocorticolimbic activity and reflected negative affect. We reassessed a sub-group of CBP+O after they briefly abstained from taking opioids. Network dynamics, but not spontaneous activity, reflected exacerbated signs of withdrawal. Our results have implications for the management and tapering of opioids in chronic pain.

Abstract
Chronic back pain (CBP) is a global health concern with significant societal and economic burden. While various predictors of back pain chronicity have been proposed, including demographic and psychosocial factors, neuroimaging studies have shown that brain characteristics can serve as robust predictors of CBP. However, large-scale, multisite validation of these predictors is currently lacking. In two independent longitudinal studies, we examined white matter diffusion imaging data and pain characteristics in patients with subacute back pain (SBP) over six- and 12-month periods. Diffusion data from individuals with CBP and healthy controls (HC) were analyzed for comparison. Whole-brain tract-based spatial statistics analyses revealed that a cluster in the right superior longitudinal fasciculus (SLF) tract had larger fractional anisotropy (FA) values in patients who recovered (SBPr) compared to those with persistent pain (SBPp), and predicted changes in pain severity. The SLF FA values accurately classified patients at baseline and follow-up in a third publicly available dataset (Area under the Receiver Operating Curve ~ 0.70). Notably, patients who recovered had FA values larger than those of HC suggesting a potential role of SLF integrity in resilience to CBP. Structural connectivity-based models also classified SBPp and SBPr patients from the three data sets (validation accuracy 67%). Our results validate the right SLF as a robust predictor of CBP development, with potential for clinical translation. Cognitive and behavioral processes dependent on the right SLF, such as proprioception and visuospatial attention, should be analyzed in subacute stages as they could prove important for back pain chronicity.

Abstract
PURPOSE This qualitative evidence synthesis aimed to identify and integrate findings where adults with fibromyalgia discussed how they managed their pain, and their perceptions of prescribed treatments from healthcare professionals. MATERIALS AND METHODS A comprehensive search strategy was implemented in PubMed, Scopus, ISI Web of Science, and Cinahl Plus databases. The GRADE-CERQual framework was used to evaluate the findings confidence. The findings were analyzed using an inductive thematic analysis approach. RESULTS A total of 35 studies (N = 728) were included. The confidence in the findings ranged from high to low confidence. Patients with fibromyalgia often do not benefit from seeking medical attention due to provider stigma, and have varying views on medication effectiveness commonly reporting feeling like "walking chemists." They find mixed effects from exercise, and consider psychological support essential, although the benefits of cognitive-behavioral therapy were controversial. Combining cognitive-behavioral therapy with physical exercise appears more effective, while natural and complementary therapies have short-term benefits and high costs. CONCLUSIONS Pain management is a source for frustration and an unmet need for patients with fibromyalgia. The current findings provide crucial insight for providers and researchers; and support the need for fibromyalgia phenotyping and precision medicine approaches to pain management.Implications for RehabilitationChronic widespread pain is the defining feature of fibromyalgia, yet pain reduction is often an unmet need for these individuals.The lack of effective treatments resulting in long-term relief proves frustrating for patients and healthcare providers.Rehabilitation professional should consider the unique insight into this complex, heterogeneous condition that this qualitative synthesis provides to better understand their patient's perspective on pain management.Given the differing perspectives on pain treatment approaches individuals with fibromyalgia report, providers should discuss with each patient their current strategies and take a patient-centered, individualized approach to form an effective treatment plan.

Abstract
Self-reported pain intensity, frequently used as an outcome in randomized clinical trials (RCTs) of chronic pain, is often highly variable and could be associated with multiple baseline factors. Thus, the assay sensitivity of pain trials (ie, the ability of the trial to detect a true treatment effect) could be improved by including prespecified baseline factors in the primary statistical model. The objective of this focus article was to characterize the baseline factors included in statistical analyses of chronic pain RCTs. Seventy-three RCTs published between 2016 and 2021 that investigated interventions for chronic pain were included. The majority of trials identified a single primary analysis (72.6%; n = 53). Of these, 60.4% (n = 32) included one or more covariates in the primary statistical model, most commonly baseline value of the primary outcome, study site, sex, and age. Only one of the trials reported information regarding associations between covariates and outcomes (ie, information that could inform prioritization of covariates for prespecification in future analyses). These findings demonstrate inconsistent use of covariates in the statistical models in chronic pain clinical trials. Prespecified adjustments for baseline covariates that could increase precision and assay sensitivity should be considered in future clinical trials of chronic pain treatments. PERSPECTIVE: This review demonstrates inconsistent inclusion and potential underutilization of covariate adjustment in analyses of chronic pain RCTs. This article highlights areas for possible improvement in design and reporting related to covariate adjustment to improve efficiency in future RCTs.

Abstract
OBJECTIVE Patients with chronic low back pain (CLBP) and comorbid depression or anxiety disorders are highly prevalent. Negative affect (NA) refers to a combination of negative thoughts, emotions, and behaviors. Patients with CLBP with high NA have greater pain, worse treatment outcomes, and greater prescription opioid misuse. We present the protocol for SYNNAPTIC (SYNergizing Negative Affect & Pain Treatment In Chronic pain). DESIGN A randomized comparative-effectiveness study of antidepressants, fear-avoidance rehabilitation, or their combination in 300 patients with CLBP with high NA. In the antidepressant- or rehabilitation-only arms, SYNNAPTIC includes an adaptive design of re-randomization after 4 months for nonresponders. SETTING A multisite trial conducted in routine pain clinical treatment settings: pain clinics and physical and occupational therapy treatment centers. METHODS Inclusion criteria include CLBP with elevated depression and anxiety symptoms. Antidepressant and rehabilitation treatments follow validated and effective protocols for musculoskeletal pain in patients with high NA. Power and sample size are based on superior outcomes of combination therapy with these same treatments in a 71-subject 4-arm pilot randomized controlled trial. CONCLUSIONS SYNNAPTIC addresses the lack of evidence-based protocols for the treatment of the vulnerable subgroup of patients with CLBP and high NA. We hypothesize that combination therapy of antidepressants plus fear-avoidance rehabilitation will be more effective than each treatment alone. TRIAL REGISTRATION ClinicalTrials.gov ID: NCT04747314.

Addict Behav 2023; 142:107668. [PMID: 36868055 DOI: 10.1016/j.addbeh.2023.107668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 12/16/2022] [Accepted: 02/15/2023] [Indexed: 02/21/2023]
Abstract
Trauma-exposure and posttraumatic stress symptoms increase risk for opioid-related problems in the context of chronic pain. Yet, there has been little exploration of moderators of the posttraumatic stress-opioid misuse association. Pain-related anxiety, defined as worry about pain and the negative consequences of pain, has shown relations to both posttraumatic stress symptoms and opioid misuse, and it may moderate the association between posttraumatic stress symptoms and opioid misuse, as well as dependence. The current study examined the moderating role of pain-related anxiety on the relationship between posttraumatic stress symptoms and opioid misuse and dependence among 292 (71.6 % female, Mage = 38.03 years, SD = 10.93) trauma exposed adults with chronic pain. Results indicated that pain-related anxiety significantly moderated the observed relations, such that compared to those with low pain-related anxiety, the relationship between posttraumatic stress symptoms and opioid misuse and dependence was stronger for those with elevated pain-related anxiety. These results highlight the importance of assessing and targeting pain-related anxiety among this trauma-exposed segment of the chronic pain population with elevated posttraumatic stress symptoms.

Abstract
BACKGROUND Prescription opioids remain a primary treatment option for patients with chronic low back pain. However, little research has examined how patients take opioids in daily life. Behavioral economics suggest that the environmental context may contribute to patients' decisions around opioid use. PURPOSE This study examined the association of self-reported environmental factors and physical activity with likelihood of taking opioids, opioid dosage, and physical pain. METHOD Patients with chronic low back pain on long-term opioid therapy (n = 34) without significant past-year opioid-related problems completed a two-week ecological momentary assessment protocol (nobservations = 1,714). RESULTS Initial multilevel models revealed multiple associations for different specific contexts with opioid use and pain. In models that collapsed specific contexts into categories (where, with whom, doing what), greater occasion-level physical activity was associated with a greater likelihood of taking opioids and greater pain, and being somewhere (v. at home) was associated with taking a smaller opioid dose. At any given occasion, being with someone (v. alone) was associated with taking a larger opioid dose, but patients who spent more time with others over the entire study took fewer opioids overall. Multilevel mediation found that pain did not mediate the association of physical activity and opioid use. CONCLUSION Results suggest that prescribed opioid use in patients with chronic low back pain is not solely determined by pain, but influenced by environmental factors, including physical activity. Psychoeducation regarding environmental factors, including how factors may be associated with both increased and decreased use of opioids, may help patients take fewer opioids more effectively.

Abstract
OBJECTIVES The risk of opioid addiction among people with chronic pain is elevated in those using opioids to self-medicate physical or emotional pain or distress. The purpose of this study is to test the main effect of distress tolerance (DT) on opioid use disorder (OUD) status in people with chronic pain, and the potential moderating effect of DT in the relationship between known addiction risk factors and the development of OUD. METHODS One hundred twenty people with chronic pain were recruited to 1 of 3 groups according to their opioid use status (ie, current methadone or buprenorphine/naloxone for OUD [n = 60], history of OUD but current prolonged opioid abstinence [n = 30, mean abstinence = 121 weeks, SD = 23.3], and opioid naive [n = 30]). Participants completed self-report measures and a cold pressor task. Multinomial logistic regression analyses were used to test if DT associated with OUD status in people with chronic pain and to compare DT to other known indicators of OUD risk. Multinomial linear regression analyses were used to test the moderation effects of DT on the relationship between various risk factors and OUD in people with chronic pain. RESULTS Analyses revealed that DT was significantly related to OUD status but did not moderate the effects of most OUD risk factors. CONCLUSIONS These results suggest that decreasing distress (eg, pain levels, craving responses, etc) may be more effective than improving tolerance to distress for the comorbid chronic pain and OUD population.

Abstract
Large variability in the individual response to even the most-efficacious pain treatments is observed clinically, which has led to calls for a more personalized, tailored approach to treating patients with pain (ie, "precision pain medicine"). Precision pain medicine, currently an aspirational goal, would consist of empirically based algorithms that determine the optimal treatments, or treatment combinations, for specific patients (ie, targeting the right treatment, in the right dose, to the right patient, at the right time). Answering this question of "what works for whom" will certainly improve the clinical care of patients with pain. It may also support the success of novel drug development in pain, making it easier to identify novel treatments that work for certain patients and more accurately identify the magnitude of the treatment effect for those subgroups. Significant preliminary work has been done in this area, and analgesic trials are beginning to utilize precision pain medicine approaches such as stratified allocation on the basis of prespecified patient phenotypes using assessment methodologies such as quantitative sensory testing. Current major challenges within the field include: 1) identifying optimal measurement approaches to assessing patient characteristics that are most robustly and consistently predictive of inter-patient variation in specific analgesic treatment outcomes, 2) designing clinical trials that can identify treatment-by-phenotype interactions, and 3) selecting the most promising therapeutics to be tested in this way. This review surveys the current state of precision pain medicine, with a focus on drug treatments (which have been most-studied in a precision pain medicine context). It further presents a set of evidence-based recommendations for accelerating the application of precision pain methods in chronic pain research. PERSPECTIVE: Given the considerable variability in treatment outcomes for chronic pain, progress in precision pain treatment is critical for the field. An array of phenotypes and mechanisms contribute to chronic pain; this review summarizes current knowledge regarding which treatments are most effective for patients with specific biopsychosocial characteristics.

Maximizing treatment efficacy through patient stratification in neuropathic pain trials. Nat Rev Neurol 2023; 19:53-64.

Abstract
Treatment of neuropathic pain remains inadequate despite the elucidation of multiple pathophysiological mechanisms and the development of promising therapeutic compounds. The lack of success in translating knowledge into clinical practice has discouraged pharmaceutical companies from investing in pain medicine; however, new patient stratification approaches could help bridge the translation gap and develop individualized therapeutic approaches. As we highlight in this article, subgrouping of patients according to sensory profiles and other baseline characteristics could aid the prediction of treatment success. Furthermore, novel outcome measures have been developed for patients with neuropathic pain. The extent to which sensory profiles and outcome measures can be employed in routine clinical practice and clinical trials and across distinct neuropathic pain aetiologies is yet to be determined. Improvements in animal models, drawing on our knowledge of human pain, and robust public-private partnerships will be needed to pave the way to innovative and effective pain medicine in the future.

Abstract
Neuropathic pain is a common chronic pain condition that is caused by a lesion or disease of the somatosensory nervous system. The multitude of sensory negative and positive sensations and associated comorbidities have a major impact on quality of life of affected patients. Current treatment options often only lead to a partial pain relief or are even completely ineffective. In addition, many clinical trials for the development of new drugs have not met the primary endpoint. Therefore, there is still an unmet clinical need in neuropathic pain syndromes. One reason for this therapeutic dilemma could be the heterogeneity of neuropathic pain with a variety of pathophysiological pain mechanisms that are expressed differently in each patient regardless of the underlying disease etiology. Reclassification of neuropathic pain syndromes therefore focuses on the underlying mechanisms of pain development rather than the disease etiology. A priori stratification of patients based on these individual mechanisms could allow the identification of potential treatment responders and thus realize the concept of a mechanism-based treatment. As no biomarkers for pain mechanisms have been discovered yet, one has to rely on surrogate markers that are thought to be closely related to these mechanisms. In this chapter, we present promising predictive biomarkers, focusing in particular on sensory symptoms and signs assessed by patient-reported outcome measures and sensory testing, and discuss how these tools might be used in clinical trials in the future.

Abstract
Prescription opioids are a primary driver of opioid-related deaths. Although craving is a substantial component of OUD, the degree to which craving leads to misuse among chronic pain patients on long-term prescription opioids is unknown. A clear understanding of the factors that lead to misuse in this vulnerable population is needed for the development of safe and effective practices for opioid taper. This narrative review summarizes the relevant literature on the role of craving in addiction and chronic pain through epidemiological and behavioral studies. The first part of this review examines the role of craving in predicting opioid use/misuse in individuals with chronic pain with and without OUD. The second part covers methods on how craving is evaluated experimentally using both subjective and objective measures and provides related findings. The overall goal of this review is to facilitate the development of a population-specific description of craving in those who use opioids to control chronic pain and to describe how it may be mechanistically linked to patterns of opioid (mis)use.

Abstract
ABSTRACT The United States faces a crisis because of the high prevalence of chronic pain, concurrent opioid use disorder, and overdose deaths. Prescription opioids remain a primary driver of opioid-related deaths. Craving is a core symptom of addiction, yet the degree to which craving plays a role in prescription opioid use among patients with chronic pain is unknown. Understanding the degree to which craving should be considered in patients with chronic pain is critical for developing effective interventions for supporting patients through opioid tapering. The current work combines data collected from (1) 2152 veterans screened for eligibility at a pain specialty care clinic at the San Francisco VA Health Care System and (2) medical records obtained from the VA Corporate Data Warehouse. We found that prescription opioid craving among veterans with chronic pain was low, with 66.4% of the sample reporting no craving and 33.6% reporting craving. We also found that craving had a small association with morphine equivalent daily dose and pain severity but was more strongly associated with depression. Craving of prescription opioids among veterans with chronic pain is complex. Findings are discussed in relation to chronic pain symptoms, psychiatric comorbidities, and demographics.

Abstract
INTRODUCTION In the past decades, the opioid crisis has heavily impacted parts of the US society and has been followed by an increase in the use of opioids worldwide. It is of paramount importance that we explore the origins of the US opioid epidemic to develop best practices to tackle the rising tide of opioid overdoses. AREAS COVERED In this expert review, we discuss opioid (over)prescription, change in perception of pain, and false advertisement of opioid safety as the leading causes of the US opioid epidemic. Then, we review the evidence about opioid dependence and addiction potential and provide current knowledge about predictors of aberrant opioid-related behavior. Lastly, we discuss different approaches that were considered or undertaken to combat the rising tide of opioid-related deaths by regulatory bodies, pharmaceutical companies, and health-care professionals. For this expert review, we considered published articles relevant to the topic under investigation that we retrieved from Medline or Google scholar electronic database. EXPERT OPINION The opioid epidemic is a dynamic process with many underlying mechanisms. Therefore, no single approach may be best suited to combat it. In our opinion, the best way forward is to employ multiple strategies to tackle different underlying mechanisms.

Abstract
Objective Individuals experience chronic pain differently, not only because of different clinical diagnoses, but also because of differing degrees of influence from biopsychosocial pain modulators. We aimed to cluster patients with chronic pain into distinct subgroups based on psychosocial characteristics and pain intensity, and we subsequently examined group differences in pain-related interference approximately 1 year later. Methods In this observational, longitudinal study, patients with chronic pain (n = 94) completed validated assessments of psychosocial characteristics and pain intensity at the beginning of COVID-19–related social distancing (April to June 2020). One year later (May to June 2021), patients completed a follow-up survey with assessments of pain interference, loneliness, social support, mindfulness, and optimism. Results A cluster analysis, using psychosocial factors and pain intensity, empirically produced three patient groups: 1) psychosocial predominant (PSP), characterized by high psychosocial distress and average pain intensity; 2) pain intensity predominant (PIP), characterized by average psychosocial distress and high pain intensity; and 3) less elevated symptoms (LES), characterized by low psychosocial distress and low pain intensity. At the 1-year follow-up, patients in the PSP and PIP clusters suffered greater pain interference than patients in the LES cluster, while patients in the PSP cluster also reported greater loneliness and lower mindfulness and optimism. Conclusions An empirical psychosocial-based clustering of patients identified three distinct groups that differed in pain interference. Patients with high psychosocial modulation of pain at the onset of social distancing (the PSP cluster) suffered not only greater pain interference but also greater loneliness and lower levels of mindfulness and optimism, which suggests some potential behavioral targets for this group in the future.

Abstract
IMPORTANCE Successful treatment of opioid misuse among people with chronic pain has proven elusive. Guidelines recommend nonopioid therapies, but the efficacy of mindfulness-based interventions for opioid misuse is uncertain. OBJECTIVE To evaluate the efficacy of Mindfulness-Oriented Recovery Enhancement (MORE) for the reduction of opioid misuse and chronic pain. DESIGN, SETTING, AND PARTICIPANTS This interviewer-blinded randomized clinical trial enrolled patients from primary care clinics in Utah between January 4, 2016, and January 16, 2020. The study included 250 adults with chronic pain receiving long-term opioid therapy who were misusing opioid medications. INTERVENTIONS Treatment with MORE (comprising training in mindfulness, reappraisal, and savoring positive experiences) or supportive group psychotherapy (control condition) across 8 weekly 2-hour group sessions. MAIN OUTCOMES AND MEASURES Primary outcomes were (1) opioid misuse assessed by the Drug Misuse Index (self-report, interview, and urine screen) and (2) pain severity and pain-related functional interference, assessed by subscale scores on the Brief Pain Inventory through 9 months of follow-up. Secondary outcomes were opioid dose, emotional distress, and ecological momentary assessments of opioid craving. The minimum intervention dose was defined as 4 or more completed sessions of MORE or supportive group psychotherapy. RESULTS Among 250 participants (159 women [63.6%]; mean [SD] age, 51.8 [11.9] years), 129 were randomized to the MORE group and 121 to the supportive psychotherapy group. Overall, 17 participants (6.8%) were Hispanic or Latino, 218 (87.2%) were White, and 15 (6.0%) were of other races and/or ethnicities (2 American Indian, 3 Asian, 1 Black, 2 Pacific Islander, and 7 did not specify). At baseline, the mean duration of pain was 14.7 years (range, 1-60 years), and the mean (SD) morphine-equivalent opioid dose was 101.0 (266.3) mg (IQR, 16.0-90.0 mg). A total of 203 participants (81.2%) received the minimum intervention dose (mean [SD], 5.7 [2.2] sessions); at 9 months, 92 of 250 participants (36.8%) discontinued the study. The overall odds ratio for reduction in opioid misuse through the 9-month follow-up period in the MORE group compared with the supportive psychotherapy group was 2.06 (95% CI, 1.17-3.61; P = .01). At 9 months, 36 of 80 participants (45.0%) in the MORE group were no longer misusing opioids compared with 19 of 78 participants (24.4%) in the supportive psychotherapy group. Mixed models demonstrated that MORE was superior to supportive psychotherapy through 9 months of follow-up for pain severity (between-group effect: 0.49; 95% CI, 0.17-0.81; P = .003) and pain-related functional interference (between-group effect: 1.07; 95% CI, 0.64-1.50; P < .001). Participants in the MORE group reduced their opioid dose to a greater extent than those in the supportive psychotherapy group. The MORE group also had lower emotional distress and opioid craving. CONCLUSIONS AND RELEVANCE In this randomized clinical trial, among adult participants in a primary care setting, the MORE intervention led to sustained improvements in opioid misuse and chronic pain symptoms and reductions in opioid dosing, emotional distress, and opioid craving compared with supportive group psychotherapy. Despite attrition caused by the COVID-19 pandemic and the vulnerability of the sample, MORE appeared to be efficacious for reducing opioid misuse among adults with chronic pain.

Abstract
STUDY OBJECTIVE VVZ-149 is a small molecule that inhibits the glycine transporter type 2 and the serotonin receptor 5-hydroxytryptamine 2A. In the present study, we investigated the efficacy and safety of VVZ-149 as a single-use injectable analgesic for treating moderate to severe postoperative pain after colorectal surgery. DESIGN Randomized, parallel group, double-blind Phase 2 clinical trial (NCT02489526). SETTING 3 academic institutions in the United States. PATIENTS 60 patients undergoing laparoscopic colorectal surgery. INTERVENTIONS A continuous 8-h intravenous infusion of VVZ-149 Injections (n = 40) or placebo (n = 20) administered after emergence from anesthesia. MEASUREMENTS The outcome measures included pain intensity (PI), opioid consumption via patient-controlled analgesia (PCA), and rescue dosing provided "as needed". Early rescue dosing with opioids postoperatively was associated with preoperative negative affect (anxiety, depression, and pain catastrophizing), enabling it to be used as an indirect measure of the affective component of pain. Efficacy outcomes were compared between treatment groups based on preoperative negative affect and early rescue dosing of opioids. MAIN RESULTS Postoperative PI was non-significantly lower in patients receiving VVZ-149 compared to those receiving placebo. The VVZ-149 group had a 34.2% reduction in opioid consumption for 24 h post-dose, along with fewer PCA demands. Somnolence and headache was higher in the intervention group. For patients characterized by high levels of preoperative negative affect, the VVZ-149 group experienced a significant pain reduction and 40% less opioid use compared to the placebo group. CONCLUSIONS VVZ-149 resulted in a non-significant reduction of postoperative pain during the first 8 h after surgery. Post hoc analysis indicates that VVZ-149 may benefit patients with negative affect who otherwise have higher postoperative opioid use. REGISTRATION NUMBER: www.clinicaltrials.gov, ID: NCT02489526.

Abstract
ABSTRACT Randomized clinical trials have demonstrated the efficacy of opioid analgesics for the treatment of acute and chronic pain conditions, and for some patients, these medications may be the only effective treatment available. Unfortunately, opioid analgesics are also associated with major risks (eg, opioid use disorder) and adverse outcomes (eg, respiratory depression and falls). The risks and adverse outcomes associated with opioid analgesics have prompted efforts to reduce their use in the treatment of both acute and chronic pain. This article presents Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) consensus recommendations for the design of opioid-sparing clinical trials. The recommendations presented in this article are based on the following definition of an opioid-sparing intervention: any intervention that (1) prevents the initiation of treatment with opioid analgesics, (2) decreases the duration of such treatment, (3) reduces the total dosages of opioids that are prescribed for or used by patients, or (4) reduces opioid-related adverse outcomes (without increasing opioid dosages), all without causing an unacceptable increase in pain. These recommendations are based on the results of a background review, presentations and discussions at an IMMPACT consensus meeting, and iterative drafts of this article modified to accommodate input from the co-authors. We discuss opioid sparing definitions, study objectives, outcome measures, the assessment of opioid-related adverse events, incorporation of adequate pain control in trial design, interpretation of research findings, and future research priorities to inform opioid-sparing trial methods. The considerations and recommendations presented in this article are meant to help guide the design, conduct, analysis, and interpretation of future trials.

Abstract
PURPOSE Precision pain medicine focuses on employing methods to assess each patient individually, identify their risk profile for disproportionate pain and/or the development of chronic pain, and optimize therapeutic strategies to target specific pathological processes underlying chronic pain. This review aims to provide a concise summary of the current body of knowledge regarding psychological, physiological, and genetic determinants of chronic pain related to precision pain medicine. METHODS Following the Scale for the Assessment of Narrative Review Articles (SANRA) criteria, we employed PubMed/Medline to identify relevant articles using primary database search terms to query articles such as: precision medicine, non-modifiable factors, pain, anesthesiology, quantitative sensory testing, genetics, pain medicine, and psychological. RESULTS Precision pain medicine provides an opportunity to identify populations at risk, develop personalized treatment strategies, and reduce side effects and cost through elimination of ineffective treatment strategies. As in other complex chronic health conditions, there are two broad categories that contribute to chronic pain risk: modifiable and non-modifiable patient factors. This review focuses on three primary determinants of health, representing both modifiable and non-modifiable factors, that may contribute to a patient's profile for risk of developing pain and most effective management strategies: psychological, physiological, and genetic factors. CONCLUSION Consideration of these three domains is already being integrated into patient care in other specialties, but by understanding the role they play in development and maintenance of chronic pain, we can begin to implement both precision and personalized treatment regimens.

Abstract
BACKGROUND CONTEXT Psychological comorbidities are important prognostic factors for low back pain (LBP). To develop improved treatment paradigms, it is first necessary to characterize and determine current patterns of treatment in this population. PURPOSE Identify how comorbid depression or anxiety in patients with LBP is related to use of healthcare resources. STUDY DESIGN/SETTING Retrospective cohort study using electronic health records from outpatient offices at a large multisite academic medical center. PATIENT SAMPLE Data from 513,088 unique patients seen between January 2010 and July 2020 (58.0% female, 52.6±19.5 years) with a diagnosis of LBP, indicated by predetermined ICD-9 and ICD-10 codes. OUTCOME MEASURES Average self-reported pain scores, absolute differences and unadjusted risk ratios to compare opioid use, emergency department visits, hospitalizations, advanced imaging orders, spinal injections, and back surgeries between cohorts. METHODS Clinical characteristics and data regarding use of healthcare resources were extracted from the electronic health record. Clinical features and patterns in healthcare utilization were determined for patients with depression or anxiety compared to those without. RESULTS Depression or anxiety was coded for 21.4% of patients at first LBP visit. Those with depression or anxiety were more likely to be on opioids (unadjusted risk ratio: 1.22, CI: [1.22,1.23]), go to the emergency department (1.31 [1.30-1.33]), be hospitalized (1.15 [1.13, 1.17]), receive advanced imaging (1.09 [1.08, 1.11]), receive an epidural steroid injection (1.16 [1.15, 1.18]), and less likely to have back surgery (0.74 [0.72, 0.77]). Differences in pain scores for those with depression/anxiety compared to those without were not clinically significant. CONCLUSIONS Depression/anxiety is associated with increased use of healthcare resources, and is not associated with clinically meaningful elevated pain scores. Limitations come from use of an aggregate data set and reliance on administrative coding.

Mindfulness-based therapy compared to cognitive behavioral therapy for opioid-treated chronic low back pain: Protocol for a pragmatic randomized controlled trial. Contemp Clin Trials 2021; 110:106548.

Abstract
OBJECTIVE Chronic low back pain (CLBP) is disabling and costly. Existing therapies have proven suboptimal, with many patients resorting to long-term opioid therapy, which can cause harms. Cognitive behavioral (CBT) and mindfulness-based (MBT) therapies can be effective and offer unique skills for safe pain coping. This article describes the protocol for a study evaluating comparative effectiveness of CBT and MBT in adults with opioid-treated CLBP. DESIGN Pragmatic, multi-center randomized controlled trial (RCT). SETTINGS Community and outpatient care. PARTICIPANTS Planned enrollment of 766 adults (383/group) with CLBP treated with long-term opioids (≥3 months; ≥15 mg/day morphine-equivalent dose). INTERVENTIONS CBT or MBT consisting of eight weekly therapist-led, two-hour group sessions, and home practice (≥30 min/day, 6 days/week) during the 12-month study. MAIN OUTCOME MEASURES Main outcome measures, collected by self-report at baseline, then three, six, nine and 12 months post-entry, include co-primary measures: pain intensity (Numeric Rating Scale) and function (Oswestry Disability Index), and secondary measures: quality of life (Medical Outcomes Study) and average daily opioid dose (Timeline Followback). Baseline scores of depression, anxiety, and opioid misuse questionnaires will be assessed as potential contributors to the heterogeneity of treatment response. Intention-to-treat, linear mixed-effects analysis will examine treatment effectiveness. Qualitative data will augment the quantitative measures. CONCLUSIONS This will be the largest RCT comparing CBT and MBT in opioid-treated CLBP. It will provide evidence on the impact of these interventions, informing clinical decisions about optimal therapy for safe, effective care, improving quality of life and decreasing opioid-related harm among adults with refractory CLBP.

Does aerobic exercise training alter responses to opioid analgesics in individuals with chronic low back pain? A randomized controlled trial. Pain 2021; 162:2204-2213. [PMID: 33394881 PMCID: PMC8203753 DOI: 10.1097/j.pain.0000000000002165] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Accepted: 12/01/2020] [Indexed: 11/25/2022]
Abstract
ABSTRACT We tested whether aerobic exercise training altered morphine analgesic responses or reduced morphine dosages necessary for adequate analgesia. Patients with chronic back pain were randomized to an 18-session aerobic exercise intervention (n = 38) or usual activity control (n = 45). Before and after the intervention, participants underwent 3 laboratory sessions (double-blinded, crossover) to assess effects of saline placebo, i.v. morphine (0.09 mg/kg), and i.v. naloxone (12 mg) on low back pain and evoked heat pain responses. Differences in evoked and back pain measures between the placebo and morphine conditions indexed morphine analgesia, with pre-post intervention changes the primary outcome. Endogenous opioid analgesia was indexed by differences in evoked and low back pain measures between the naloxone and placebo conditions. A Sex X Intervention interaction on the analgesic effects of morphine on visual analogue scale back pain intensity was observed (P = 0.046), with a similar trend for evoked pain threshold (P = 0.093). Male exercisers showed reduced morphine analgesia pre-post intervention, whereas male controls showed increased analgesia (with no differences in females). Of clinical significance were findings that relative to the control group, aerobic exercise produced analgesia more similar to that observed after receiving ≈7 mg morphine preintervention (P < 0.045). Greater pre-post intervention increases in endogenous opioid function (from any source) were significantly associated with larger pre-post intervention decreases in morphine analgesia (P < 0.046). The overall pattern of findings suggests that regular aerobic exercise has limited direct effects on morphine responsiveness, reducing morphine analgesia in males only.

Abstract
Opioids are commonly prescribed for the management of patients with chronic noncancer pain. Despite the potential analgesic benefits of opioids, long-term opioid therapy (LTOT) may be accompanied by problems such as opioid misuse and opioid use disorder (OUD). In this review, we begin with a description of opioid misuse and OUD and the patient-specific factors associated with these problems among patients with chronic pain. We will focus primarily on highlighting the predominant role played by psychological factors in the occurrence of opioid misuse and OUD in these patients. Several psychological factors have been found to be associated with opioid use problems in patients with chronic pain, and evidence indicates that patients presenting with psychological disturbances are particularly at risk of transitioning to long-term opioid use, engaging in opioid misuse behaviors, and developing OUD. The biological factors that might underlie the association between psychological disturbances and opioid use problems in patients with chronic pain have yet to be fully elucidated, but a growing number of studies suggest that dysfunctions in reward, appetitive, autonomic, and neurocognitive systems might be involved. We end with an overview of specific types of psychological interventions that have been put forward to prevent or reduce the occurrence of opioid misuse and OUD in patients with chronic pain who are prescribed LTOT.

Abstract
Clinical outcome assessments (COAs) measure outcomes that are meaningful to patients in clinical trials and are critical for determining whether a treatment is effective. The objectives of this study are to (1) describe the different types of COAs and provide an overview of key considerations for evaluating COAs, (2) review COAs and other outcome measures for chronic pain treatments that are recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) or other expert groups, and (3) review advances in understanding pain-related COAs that are relevant to clinical trials. The authors reviewed relevant articles, chapters, and guidance documents from the European Medicines Agency and U.S. Food and Drug Administration. Since the original core set of outcome measures were recommended by IMMPACT 14 years ago, several new advancements and publications relevant to the measurement or interpretation of COAs for chronic pain trials have emerged, presenting new research opportunities. Despite progress in the quality of measurement of several outcome domains for clinical trials of chronic pain, there remain some measurement challenges that require further methodological investigation.

Abstract
There is tremendous interpatient variability in the response to analgesic therapy
(even for efficacious treatments), which can be the source of great frustration
in clinical practice. This has led to calls for “precision
medicine” or personalized pain therapeutics (ie, empirically based
algorithms that determine the optimal treatments, or treatment combinations, for
individual patients) that would presumably improve both the clinical care of
patients with pain and the success rates for putative analgesic drugs in phase 2
and 3 clinical trials. However, before implementing this approach, the
characteristics of individual patients or subgroups of patients that increase or
decrease the response to a specific treatment need to be identified. The
challenge is to identify the measurable phenotypic characteristics of patients
that are most predictive of individual variation in analgesic treatment
outcomes, and the measurement tools that are best suited to evaluate these
characteristics. In this article, we present evidence on the most promising of
these phenotypic characteristics for use in future research, including
psychosocial factors, symptom characteristics, sleep patterns, responses to
noxious stimulation, endogenous pain-modulatory processes, and response to
pharmacologic challenge. We provide evidence-based recommendations for core
phenotyping domains and recommend measures of each domain.

Abstract
The opioid epidemic is an ongoing concern in the United States and efforts to ameliorate this crisis are underway on multiple fronts. Opiate use is an important consideration for patients undergoing lumbar spine surgery with concurrent psychiatric diagnoses and more information is needed regarding the factors involved in these patients. That information may help guide opioid prescribing practices for individual patients with certain psychiatric conditions that are undergoing these procedures. This study was done to identify psychiatric conditions that are associated with preoperative and postoperative opioid use in this cohort of veteran patients undergoing elective lumbar spine surgery.A 3 month preoperative and 3 month postoperative chart review was conducted on 25 patients per year who underwent elective lumbar spine surgery over a 16-year period at the Veterans Affairs Nebraska-Western Iowa Healthcare Center (n = 376 after exclusion criteria applied). The association between psychiatric comorbidities and use of opioids during the 90-day period after surgery was assessed using a linear model that adjusted for surgical type, opioid use prior to surgery, and other relevant comorbidities.Patients are more likely to use opioids preoperatively if they have major depression (P = .02), hepatitis C (P = .01), or musculoskeletal disorders (P = .04). PTSD (P = .02) and lumbar fusion surgery (P < .0001) are associated with increased postoperative use, after adjusting for preoperative use and other comorbidities.Certain psychiatric comorbidities are significantly correlated with opioid use for this cohort of lumbar spine surgery patients in the preoperative and postoperative periods. Awareness of an individual's psychiatric comorbidity burden may help guide opioid prescription use.

Abstract
BACKGROUND Many retired National Football League (NFL) athletes manage pain with opioids during their playing careers and in retirement, though the longitudinal association between opioid use and health outcomes pertinent to an NFL career are not yet known. This study aimed to assess the relationship between opioid use in 2010 and current use, depressive symptoms, and health related quality of life (HRQoL) among NFL retirees. METHODS Former NFL athletes from the Retired NFL Players Association initially recruited in 2010 for a study examining risk factors of opioid use and misuse were re-contacted (N = 89) from 2018 to 2019 and administered measures of pain, opioid use, depressive symptoms, and HRQoL. Binomial regression examined the association between 2010 opioid use with current use, moderate-severe depressive symptoms, and average and above HRQoL (physical and mental) while controlling for covariates. RESULTS Nearly 50 % of retirees using opioids in 2010 currently used. Compared to non-users, retirees who used opioids in 2010 had greater odds of current use (AOR: 3.71, 95 % CI: 1.02-13.56, p = 0.046) and experiencing moderate-severe depressive symptoms (AOR: 5.93, 95 % CI: 1.15-30.54, p = 0.033). Retirees reporting use in 2010 also evidenced lower odds of reporting average or above mental HRQoL (AOR: 0.13, 95 % CI: 0.03-0.67, p = 0.015) compared to non-users. CONCLUSIONS This study showed that among NFL retirees, early retirement opioid use predicted current use and deleterious effects on mental health, including moderate-severe depressive symptoms approximately nine years later. This investigation further supports the importance of early intervention of pain and opioid use among this population.

Abstract
Background: Psychological factors of patients may influence physicians’ decisions on prescribing opioid analgesics. However, few studies have sought to identify these factors. The present study had a double objective: (1) To identify the individual factors that differentiate patients who had been prescribed opioids for the management of chronic back pain from those who had not been prescribed opioids and (2) to determine which factors make significant and independent contributions to the prediction of opioid prescribing. Methods: A total of 675 patients from four primary care centers were included in the sample. Variables included sex, age, pain intensity, depressive symptoms, pain catastrophizing, and pain acceptance. Results: Although no differences were found between men and women, participants with chronic noncancer pain who were prescribed opioids were older, reported higher levels of pain intensity and depressive symptoms, and reported lower levels of pain-acceptance. An independent association was found between pain intensity and depressive symptoms and opioid prescribing. Conclusions: The findings suggest that patient factors influence physicians’ decisions on prescribing opioids. It may be useful for primary care physicians to be aware of the potential of these factors to bias their treatment decisions.

Abstract
OBJECTIVE Serotonin norepinephrine reuptake inhibitors (SNRIs) are commonly co-prescribed with opioids for chronic pain. The purpose of this study was to describe pain and mood response to venlafaxine among older adults with chronic low back pain (CLBP) and depression relative to opioid exposure. DESIGN Secondary analyses were collected from a randomized clinical trial testing a stepped-care approach to comorbid pain and depression in older patients: the Addressing Depression and Pain Together study (ADAPT: 2010-2016). SETTING University-based late-life mental health research clinic. SUBJECTS Two hundred twenty-seven adults aged 65+ years with CLBP and depression. METHODS Participants received six weeks of lower-dose venlafaxine (≤150 mg/d). Pain and depression were measured each week. Response for both pain and depression at the end of six weeks was defined by a ≥30% improvement on a 0-20 numeric rating scale for low back pain and a Patient Health Questionnaire-9 score ≤5. Opioid exposure was analyzed as prescribed (yes or no) and by morphine equivalent dosing (MED). RESULTS Patients co-prescribed an opioid were less likely to report a pain response to venlafaxine. MED was negatively correlated with pain response. Depression response was not impacted. CONCLUSIONS Opioids are negatively associated with older adults' early analgesic response to lower-dose venlafaxine. These findings suggest that clinicians may wish to consider either nonopioid or alternative antidepressant approaches to pain management in these complex patients. It is reassuring that opioids do not prevent depression response. Future research should examine both longer duration of treatment and a wider range of doses.

Abstract
Introduction Chronic lower back pain is a leading cause of disability in US adults. Opioid use continues to be controversial despite the Centers for Disease Control and Prevention guidance on chronic pain management to use nonpharmacologic and nonopioid pharmacologic interventions. The objectives of the study were to assess the impact of early physical therapy (PT) intervention on improving functionality and reducing opioid burden in patients with chronic lower back pain. Methods A single-center, retrospective chart review of patients receiving ≥6 PT visits and treated with either opioids first (OF) or PT first (PTF) therapy for chronic lower back pain were evaluated. Concomitant use of nonopioid and nonpharmacologic therapy was permitted. The Oswestry Disability Index (ODI), a survey measuring functionality, was recorded for PTF group. Pain scores and medication use including opioids were collected at treatment initiation and completion. Results One hundred and eighty patients were included in three groups: OF group (n = 60), PTF group (n = 60), and PTF + ODI group (n = 60). The PTF + ODI group had mean ODI reduction of 11.9% (P < .001). More OF patients were lost to follow up (68.3%) or failed PT (60%) compared to the PTF group, 38.3% and 3.3% (P < .001). Reduction in both opioid and nonopioid medications as well as pain scores were observed but not statistically significant. Discussion Early PT resulted in improved functionality, decreased pain, and reduced medication use upon PT completion. These findings suggest PT, along with nonopioid modalities, are a viable first-line option for the management of chronic lower back pain.

Abstract
Introduction Postoperative pain management and opioid use following endoscopic skull base surgery (ESBS) is not well understood. A subset of patients requires additional opioid prescription (AOP) in the postoperative period. The objective of this study is to describe the incidence of AOP, as well as evaluate patient and surgical characteristics that may predict additional pain management requirements following ESBS. Methods A retrospective review of cases undergoing ESBS between November 2016 and August 2018 was performed. We reviewed patients' sociodemographic and clinical data, and Controlled Substance Utilization Review and Evaluation System (CURES) records. Stepwise multivariable logistic regressions were performed to evaluate the factors associated with AOP within 60 days following surgery. Results A total of 42 patients were identified. Indications for ESBS included intracranial mass (64.2%), sinonasal malignancy (23.8%), and skull base reconstruction (9.5%). AOP were recorded in nine patients (21.4%). There were no significant differences in operative factors, including approach, lesion location, or perioperative analgesia between the two cohorts. On multivariable logistic regression, we found that younger age (odds ratio [OR]: 0.891, 95% confidence interval [CI]: 0.79-1.00, p = 0.050), comorbid depression (OR: 86.48, 95% CI: 1.40-5,379.07, p = 0.034), and preoperative opioid use (OR: 104.45, 95% CI: 1.41-7,751.10, p = 0.034) were associated with additional prescriptions postoperatively. Conclusion The requirement for extended postoperative opioid pain control is common after ESBS. Patient demographics including age and psychosocial factors, such as depression may predict the need for AOP after ESBS. These results suggest that patient-driven factors, rather than surgical characteristics, may determine the need for prolonged pain control requirements after ESBS.

Abstract
BACKGROUND Data linking labor pain and postpartum depression are emerging. Robust, prospective evaluations of this relationship while factoring other important variables are lacking. We assessed perinatal pain and other factors predicting postpartum depression (PPD) symptoms. METHODS Third trimester women, stratified by a priori plan to receive or avoid labor epidural analgesia, were longitudinally followed from the prenatal period through labor and delivery, until 6 weeks and 3 months postpartum. Electronic pain data was collected hourly during labor in real time, capturing pain unpleasantness, intensity, pain management satisfaction, and expectations. Prenatal and postpartum data included anxiety, depression, the Brief Pain Inventory (BPI), pain catastrophizing, resiliency, and perceived social support and stress. The primary outcome was Edinburgh Postnatal Depression Score (EPDS) as a marker of PPD symptoms. The primary pain variable of interest was labor pain emotional valence (unpleasantness burden, area under the curve for entire labor duration). Single and multivariable linear regressions examined perinatal pain variables in relation to EPDS. RESULTS Of 72 subjects included, 55 planned/received labor epidural analgesia and 17 planned avoidance/avoided it. In the planned epidural group, the emotional valence of labor pain independently predicted six-week EPDS (labor pain unpleasantness burden, R2 = 0.42, P = 0.002). In addition to labor pain, prenatal and postpartum pain variables from the BPI independently predicted six-week EPDS. Three-month depression scores were linked to labor and acute pain (6 weeks postpartum), but not to chronic (3 months postpartum) pain variables. Intrapartum pain management satisfaction and expectations were largely met or exceeded and did not differ between analgesia groups. CONCLUSION For susceptible women, pain at all perinatal time points-prenatal, labor, and postpartum-appear to be independently linked to depression scores at 6 weeks postpartum. The relationships are true, even though satisfaction and expectations regarding labor pain management were met or exceeded. These data support the concept that labor and acute postpartum pain influences both acute and long-term PPD symptoms, although additional data are needed to assess how analgesia preference interacts with these relationships.

Abstract
AIM Adolescents in the criminal justice system, called justice-involved children (JIC), are particularly vulnerable in the modern opioid misuse (OM) epidemic. After release, relapse and overdose occur at higher rates than the general population. The current study assesses optimism and likelihood of P30D consumption of non-prescription or illicit opioids among JIC. METHODS The study examines a sample of 79,960 JIC from the Florida Department of Juvenile Justice. Multivariate logistic regression was employed, controlling for gender, race, family income, age, history of mental problems, history of depression, and county of residence. RESULTS JIC who reported very low optimism on the final screen had over 8 times the odds of meeting criteria for P30D OM compared to those with high optimism while adjusting for covariates. CONCLUSIONS Further research is needed to understand the potential for optimism to serve as a protective factor. Optimism can be developed, and therefore can possibly be incorporated to design novel interventions or integrated into empirically validated treatment programs to precipitate uptake.

Abstract
BACKGROUND The USA is currently enduring an opioid crisis. Identifying cost-effective, easy-to-implement behavioral measures that predict treatment outcomes in opioid misusers is a crucial scientific, therapeutic, and epidemiological goal. METHODS The current study used a mixed cross-sectional and longitudinal design to test whether a behavioral choice task, previously validated in stimulant users, was associated with increased opioid misuse severity at baseline, and whether it predicted change in opioid misuse severity at follow-up. At baseline, data from 100 prescription opioid-treated chronic pain patients were analyzed; at follow-up, data were analyzed in 34 of these participants who were non-misusers at baseline. During the choice task, participants chose under probabilistic contingencies whether to view opioid-related images in comparison with affectively pleasant, unpleasant, and neutral images. Following previous procedures, we also assessed insight into choice behavior, operationalized as whether (yes/no) participants correctly self-reported the image category they chose most often. RESULTS At baseline, the higher choice for viewing opioid images in direct comparison with pleasant images was associated with opioid misuse and impaired insight into choice behavior; the combination of these produced especially elevated opioid-related choice behavior. In longitudinal analyses of individuals who were initially non-misusers, higher baseline opioid v. pleasant choice behavior predicted more opioid misuse behaviors at follow-up. CONCLUSIONS These results indicate that greater relative allocation of behavior toward opioid stimuli and away from stimuli depicting natural reinforcement is associated with concurrent opioid misuse and portends vulnerability toward future misuse. The choice task may provide important medical information to guide opioid-prescribing practices.

Abstract
The opioid epidemic is a significant public health concern linked to chronic pain. Despite efforts to change opioid prescribing practices for chronic pain, opioid-involved overdoses remain at an all-time high. Research focused on identifying individual difference factors for problematic opioid misuse in the context of chronic pain have identified certain psychological variables that may confer heightened risk for opioid-related problems. Anxiety sensitivity, or fear of anxiety-related physical sensations, has been linked to opioid-related problems among adults with chronic pain. Yet, it is possible that these relations may not be distributed equally in society, and sex differences may be one avenue by which these relations differ. Therefore, the current study examined the moderating role of sex on the relation between anxiety sensitivity, current opioid misuse, and severity of opioid dependence among 428 adults (74.9% female, Mage = 38.28 years, SD = 11.06) with chronic pain. Results indicated that the relation between anxiety sensitivity and current opioid misuse (ΔR2 = 0.005, B = 0.12, SE = 0.06, p = 0.04), and opioid dependence (ΔR2 = 0.01, B = 0.04, SE = 0.02, p = 0.007) was stronger for males compared to females. These results suggest that anxiety sensitivity may be associated with opioid-related problems to a greater extent for males than females. Continued research is needed to examine how these sex differences may impact clinical treatment for opioid-related problems.

Abstract
Chronic low back pain (CLBP) conditions are highly prevalent and constitute the leading cause of disability worldwide. The Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the US Food and Drug Administration and the American Pain Society (APS), have combined to create the ACTTION-APS Pain Taxonomy (AAPT). The AAPT initiative convened a working group to develop diagnostic criteria for CLBP. The working group identified 3 distinct low back pain conditions which result in a vast public health burden across the lifespan. This article focuses on: 1) the axial predominant syndrome of chronic musculoskeletal low back pain, 2) the lateralized, distally-radiating syndrome of chronic lumbosacral radicular pain 3) and neurogenic claudication associated with lumbar spinal stenosis. This classification of CLBP is organized according to the AAPT multidimensional framework, specifically 1) core diagnostic criteria; 2) common features; 3) common medical and psychiatric comorbidities; 4) neurobiological, psychosocial, and functional consequences; and 5) putative neurobiological and psychosocial mechanisms, risk factors, and protective factors. PERSPECTIVE: An evidence-based classification of CLBP conditions was constructed for the AAPT initiative. This multidimensional diagnostic framework includes: 1) core diagnostic criteria; 2) common features; 3) medical and psychiatric comorbidities; 4) neurobiological, psychosocial, and functional consequences; and 5) putative neurobiological and psychosocial mechanisms, risk factors, and protective factors.

Clinical Effectiveness of Decision Support for Prescribing Opioids for Chronic Noncancer Pain: A Prospective Cohort Study.

[PMID: 32113620 PMCID: PMC7061936 DOI: 10.1016/j.jval.2019.09.2748] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 09/03/2019] [Accepted: 09/06/2019] [Indexed: 05/10/2023]
Abstract
OBJECTIVES This prospective cohort study examines the clinical effectiveness of electronic medical record clinical decision support (EMR CDS) for opioid prescribing. METHODS Data analysis included primary care patients with chronic opioid therapy for noncancer pain seen within an integrated health delivery system in Louisiana between January 2017 and October 2018. EMR CDS incorporated an opioid health maintenance tool to display the status of risk mitigation, and the medication order embedded the morphine equivalent daily dose (MEDD) calculator and a hyperlink to the Louisiana pharmacy drug monitoring program. Outcome measures included change in the average MEDD and rates of opioid risk mitigation, hospitalization, and emergency department use. RESULTS Among 14 221 patients, 9% had prescriptions with an average MEDD ≥90 mg. There were no significant changes in MEDD after EMR CDS implementation. Increasing age, Charlson Comorbidity Index score, female sex, black non-Hispanic race, non-opioid pain medication co-prescriptions, and specialty referrals were associated with a lower odds of MEDD ≥90 (high-dose threshold). Medicare or self-pay, substance abuse history, and pain agreements were associated with increased odds of prescribing above this high-dose threshold. After incorporation of EMR CDS, patients had higher rates of urine drug screens (17% vs 7%) and naloxone prescriptions (3% vs 1%, all P < .001). In addition, specialty referrals to physical or occupational therapy, orthopedics, neurology, and psychiatry or psychology increased in the postintervention period. Although emergency department use decreased (rate ratio 0.92; 95% confidence interval 0.89-0.95), hospitalization rates did not change. CONCLUSIONS EMR CDS improved adherence to opioid risk mitigation strategies. Further research examining which practice redesign interventions effectively reduce high-dose opioid prescribing is needed.

Abstract
OBJECTIVE Prescribed opioids for chronic pain management contribute significantly to the opioid crisis. There is a need to understand the real-world benefits that, despite risks, lead chronic pain patients to persist in opioid use. Negative reinforcement models of addiction posit that individuals use substances to reduce aversive states but have seldom been applied to prescribed opioids. Using ecological momentary assessment, we examined reciprocal associations between opioid use and physical pain, for which opioids are prescribed, and negative affect (NA), for which they are not. METHOD Chronic low back pain patients on long-term opioid therapy (n = 34) without significant past-year opioid misuse reported multiple times daily via smartphone over 2 weeks (nobservations = 2,285). We hypothesized that pain and NA would be positively associated with subsequent opioid use, and that use would be negatively associated with subsequent pain and NA. RESULTS Time-lagged multilevel models indicated that participants were more likely to use opioids and in larger doses following elevated pain and NA. There was also an interaction of concurrent pain and NA on opioid dose. In turn, participants reported reduced pain and NA following larger doses. Additionally, individuals at high risk for opioid misuse, compared with low risk, took larger doses following pain, but also experienced smaller subsequent pain and NA reductions. CONCLUSIONS Opioid use was bidirectionally associated with pain and NA. Findings fit negative reinforcement models associated with risk of developing opioid use disorder. Educating patients and providers about negative reinforcement may help reduce opioid use and opioid-associated risks. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
Aims The aim of this study was to characterize the relationship between pre- and postoperative opioid use among patients undergoing common elective orthopaedic procedures Patients and Methods Pre- and postoperative opioid use were studied among patients from a national insurance database undergoing seven common orthopaedic procedures using univariate log-rank tests and multivariate Cox proportional hazards analyses. Results A total of 98 769 patients were included; 35 701 patients were opioid-naïve, 11 621 used opioids continuously for six months before surgery, and 4558 used opioids continuously for at least six months but did not obtain any prescriptions in the three months before surgery. Among opioid-naïve patients, between 0.76% and 4.53% used opioids chronically postoperatively. Among chronic preoperative users, between 42% and 62% ceased chronic opioids postoperatively. A three-month opioid-free period preoperatively led to a rate of cessation of chronic opioid use between 82% and 93%, as compared with between 31% and 50% with continuous preoperative use (p < 0.001 for significant changes in opioid use before and after surgery in each procedure). Between 5.6 and 20.0 preoperative chronic users ceased chronic use for every new chronic opioid user. Risk factors for chronic postoperative use included chronic preoperative opioid use (odds ratio (OR) 4.84 to 39.75; p < 0.0001) and depression (OR 1.14 to 1.55; p < 0.05 except total hip arthroplasty). With a three-month opioid-free period before surgery, chronic preoperative opioids elevated the risk of chronic opioid use only mildly, if at all (OR 0.47 to 1.75; p < 0.05 for total shoulder arthroplasty, rotator cuff repair, and carpal tunnel release). Conclusion Chronic preoperative opioid use increases the risk of chronic postoperative use, but an opioid-free period before surgery decreases this risk compared with continuous preoperative use Cite this article: Bone Joint J 2019;101-B:1570–1577

Ethosuximide improves chronic pain-induced anxiety- and depression-like behaviors. Eur Neuropsychopharmacol 2019; 29:1419-1432.

Abstract
Chronic pain is a heavy burden disease. Current treatments are generally weakly effective or associated with adverse effects. New therapeutic approaches are therefore needed. Recent studies have suggested T-type calcium channels as an attractive target for the treatment of chronic pain. In this perspective, it was decided to perform a preclinical evaluation of the efficacy of ethosuximide, a T-type channel blocker used clinically as an antiepileptic, as a novel pharmacological treatment for chronic pain. Assessment of the effect of ethosuximide was thus made in both nociception and pain-related comorbidities as anxiety and depression are frequently encountered in chronic pain patients. Our results show that such symptoms occurred in three animal models of chronic pain designed to reflect traumatic neuropathic, chemotherapy-induced neuropathic and inflammatory pain conditions. Administration of ethosuximide reduced both chronic pain and comorbidities with a marked intensity ranging from partial reduction to a complete suppression of symptoms. These results make ethosuximide, and more broadly the inhibition of T-type calcium channels, a new strategy for the management of uncontrolled chronic pain, likely to improve not only pain but also the accompanying anxiety and depression.

Abstract
Sex-related differences in pain and opioids has been the focus of many researches. It is demonstrated that women experience greater clinical pain, lower pain threshold and tolerance, more sensitivity and distress to experimentally induced pain compared to men. Sex differences in response to opioid treatment revealed inconsistent results. However, the etiology of these disparities is not fully elucidated. It is, therefore, conceivable now that this literature merits to be revisited comprehensively. Possible multifaceted factors seem to be associated. These include neuroanatomical, hormonal, neuroimmunological, psychological, social and cultural aspects and comorbidities. This review aims at providing an overview of the substantial literature documenting the sex differences in pain and analgesic response to opioids from animal and human studies within the context of the modulatory effects of the aforementioned factors. A detailed and critical discussion of the cellular and molecular signaling pathways underlying the modulatory actions of gonadal hormones in the sexual dimorphism in pain processing and opioid analgesia is extensively presented. It is indicated that sexual dimorphic activation of certain brain regions contributes to differential pain sensitivity between females and males. Plausible crosstalk between sex hormones and neuroimmunological signaling pertinent to toll-like and purinergic receptors is uncovered as causal cues underlying sexually dimorphic pain and opioid analgesia. Conceivably, a thorough understanding of these factors may aid in sex-related advancement in pain therapeutic management.

Abstract
Introduction Chronic pain patients frequently report having sleep disturbances and many tend to stay up during the night and then sleep into the day. Objectives This study was designed to compare a heterogeneous group of persons with chronic pain who reported typically going to bed between the hours of 9 pm and midnight with those who go to bed at other hours of the day and night. Methods Two hundred seventy-nine participants were divided between those who reported going to bed between the hours of 9 pm and midnight (N = 205) and those who reported having atypical bedtimes (N = 74) based on pre-post questionnaire data and average pain assessments from a smartphone pain application (app). Results Those individuals in the atypical bedtime group reported waking up more frequently and getting fewer hours sleep (P < 0.05). These individuals also reported significantly higher pain scores, activity interference, and taking more prescription opioid medication compared with those who had typical bedtimes (P < 0.05). Based on average 3-month daily assessments, those subjects with an atypical bedtime consistently reported more sleep disturbances, pain, activity interference, negative mood, and general worsening conditions over time, and elevated pain catastrophizing, pain-related disability, emotional distress scores, and more prescription medication for pain at 3-month follow-up (P < 0.01). Conclusion These results support the importance of providers asking patients with pain about what time they typically go to bed at night to gain a greater understanding of their lifestyle habits. Future studies are needed to further determine the importance of maintaining a typical bedtime among patients with chronic pain.

Abstract
Chronic breathlessness is a multidimensional and aversive symptom, which is often poorly explained by underlying pathophysiology [1]. For many sufferers, breathlessness is refractory to maximal medical therapies that target disease processes [2]. However, opioids are thought to be a possible therapeutic avenue to treat symptomology independently of disease [3]. Importantly, research in chronic pain has demonstrated that qualities such as anxiety and depression (collectively termed negative affect here) can both exacerbate symptoms [4] and reduce opioid efficacy [5, 6]. Therefore, it may be pertinent to consider such behavioural factors when contemplating the use of opioids for breathlessness. Diminished opioid efficacy in the treatment of breathlessness is related to negative affect and anticipatory brain activity in the anterior cingulate and medial prefrontal cortex.http://bit.ly/2LXyyDo

Abstract
OBJECTIVE The psychological health of patients with chronic low back pain (CLBP) influences their response to a number of conservative and invasive pain treatments. However, evidence is still scarce regarding the impact of anxiety and depression in the clinical outcomes of multidisciplinary pain management over time. This study, based on longitudinal data from a clinical practice setting, aimed to assess the effectiveness of the usual multidisciplinary approach provided to CLBP patients and to explore the impact of anxiety and depression symptoms and their interaction on clinical outcomes. METHODS In this study, participants included were adult patients in their first consultation in a multidisciplinary chronic pain clinic. Anxiety and depression symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS). The Brief Pain Inventory (BPI) and the Shortened Treatment Outcomes in Pain Survey (S-TOPS) were used to assess outcomes. Linear mixed effects models were used to assess the impact of anxiety, depression, and their interaction on treatment outcomes. RESULTS A total of 284 patients (age 60.4 ± 13.7 years, 74.6% female) with CLBP were included at baseline. The majority of patients had both anxiety and depression and experienced higher pain severity (P < 0.001) and higher pain-related disability (P < 0.001). Anxiety and depression mainly predicted changes in pain interference over time. Their interaction significantly predicted changes in pain interference. CONCLUSIONS Anxiety, depression, and their interaction are associated with changes in pain disability at one-year follow-up. These findings encourage the pretreatment screening of anxiety and depression as independent symptoms in patients with CLBP in order to design more tailored and effective multidisciplinary treatments.
