Abstract
BACKGROUND AND AIMS People with opioid use disorder (OUD) commonly experience pain including chronic pain. Despite the high prevalence, few studies have systematically examined the prevalence and correlates of pain among people seeking or receiving opioid agonist treatment (OAT) for OUD. This review aimed to determine the prevalence of pain in this population globally, and estimate the association between chronic pain and other demographic and clinical characteristics. METHODS Electronic searches were conducted in three databases (Medline, Embase and PsycINFO) from the inception until October 2022. Eligible studies reported prevalence rates of current and/or chronic pain. Meta-analyses examining the main prevalence estimates were conducted by Stata SE 18.0, and comorbid clinical conditions were analysed by Review Manager 5.4. RESULTS Fifty-six studies (n participants = 35 267) from sixty-seven publications were included. Prevalence estimates of current and chronic pain were reported in 27 (48.2%) and 40 studies (71.4%), respectively. Most studies were conducted in North America (71.4%, n = 40) and used cross-sectional designs (64.3%, n = 36). Meta-analyses revealed a pooled prevalence of 60.0% (95% confidence interval [CI]: 52.0-68.0) for current pain and 44.0% [95% CI: 40.0-49.0] for chronic pain. Chronic pain was positively associated with older age (mean deviation of mean age: 2.39 years, 95% CI: 1.40-3.37; I2 = 43%), unemployment (odds ratio [OR] = 0.57, 95% CI: 0.42-0.76; I2 = 78%), more severe mental health symptoms (e.g. more severe depression (standardised mean difference [SMD] of mean scores: 0.45, 95% CI: 0.20-0.70; I2 = 48%) and anxiety symptoms (SMD: 0.52, 95% CI: 0.17-0.88; I2 = 67%), and hepatitis C (OR = 1.41, 95% CI: 1.03-1.94; I2 = 0%). No association was observed between chronic pain and the onset and type of OAT, geographic location, study design, survey year, participant age or use of specific pain assessment tools. CONCLUSIONS There appears to be a high prevalence of pain among people seeking or receiving opioid agonist treatment for opioid use disorder compared with the general population, with positive associations for older age, unemployment, hepatitis C and the severity of some mental health symptoms.

Kim J, Lee J, Thornhill TA, Dennett J, Lu H, Howell B, Grau LE, Fiellin DA, Heimer R, Gonsalves G. Accessibility of Opioid Treatment Programs Based on Conventional vs Perceived Travel Time Measures. JAMA Netw Open 2024; 7:e240209. [PMID: 38376839 PMCID: PMC10879949 DOI: 10.1001/jamanetworkopen.2024.0209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 01/04/2024] [Indexed: 02/21/2024] Open
Abstract
Importance Transportation barriers have long been associated with poorer health outcomes; this burden is especially acute for individuals with opioid use disorder (OUD), a chronic disease often associated with low socioeconomic status. Conventional travel time analyses may not fully account for experiential components of travel, thereby understating the true travel burden and overstating treatment accessibility to opioid treatment programs (OTPs). Objective To develop a metric of feels-like accessibility for those using public transit to access OTPs that accounts for the realistic travel burden on individuals with OUD. Design, Setting, and Participants This cross-sectional study integrated high-resolution transit schedules and operating hours of OTPs to measure feels-like accessibility. Feels-like accessibility considers the differential outcomes of out-of-vehicle travel components and more realistically reflects individuals' transportation burden than conventional accessibility measures. Gini indices and spatial regression models were used to investigate inequities in accessibility. Geocoded data for residential addresses of 1018 overdose fatalities in Connecticut in 2019 were used as a proxy for the treatment needs of individuals with OUD. Data were analyzed between May and August 2023. Main Outcomes and Measures Conventional and feels-like accessibility scores. Exposures Fluctuations in public transit frequencies over the course of the day and the limited operating hours of the OTPs. Results Of the 1018 individuals in the study, the mean (SD) age at death was 43.7 (12.6) years, 784 individuals (77%) were men, 111 (11%) were African American, and 889 (87%) were White, with other racial and ethnic categories including 18 individuals (2%). A total of 264 individuals in the sample (26%) could not access an OTP within 180 minutes. For those who could access these facilities, the average 1-way travel time was 45.6 minutes, with individuals spending approximately 70% of their trip duration on out-of-vehicle travel components. The conventional accessibility metric underestimates individuals' travel burden to OTPs as well as the inequity in accessibility compared with the feels-like accessibility metric. For example, the median (range) conventional accessibility score, defined as the number of OTPs within 120 minutes of transit travel time, was 5.0 (0.0-17.0); the median (range) feels-like accessibility score, defined as the number of OTPs within 120 minutes of transit travel time weighted to account for in- and out-of-vehicle segments, was 1.0 (0.0-10.0). There is a considerable temporal variation in travel time and accessibility depending on the departure times. Conclusions and Relevance In this cross-sectional study of travel burdens, the calculated feels-like accessibility scores, which consider the differential outcomes of out-of-vehicle travel components (eg, walking and waiting), could better and more realistically reflect passengers' transportation burden. Policy recommendations derived from the conventional accessibility metric could be misleading, and decision-makers should use feels-like accessibility metrics that adequately capture individuals' travel burdens. In the context of access to OTPs, the findings from this study suggest that opening new OTP sites to address gaps in access due to distance to services or extending hours of operation at existing sites may ameliorate the travel burden for individuals.

Abstract
INTRODUCTION Acute pain is common after injury. This study intended to evaluate the feasibility of quantifying pain experience over an entire admission using "area under the pain curve" and to identify factors associated with increased pain. METHODS This retrospective single-center study included all trauma patients admitted from 2013 to 2020. Maximum pain scores were extracted for each day. Pain was defined as area under the curve (AUC) of maximum pain scores/day plotted against time. Injury patterns were analyzed by dichotomizing Abbreviated Injury Scale (AIS) scores (AIS < 3 versus AIS ≥ 3) for each body region. Urinary drug screen results were collected from admission data. A general linear model was used to determine which injury patterns, mechanisms, and age groups were predictive of increased AUC in all patients together and separate by operative and nonoperative groups. RESULTS We identified 21,640 patients, of which 70% were male and 83% had suffered blunt injury. Overall injury severity was associated with increased pain experience. Serious head injury, younger age, and older age (compared to 45-49 y) were associated with decreased pain. Spinal injuries, thoraco-abdominal injuries, and combined thoracic and lower extremity injuries were predictive of increased pain. Compared to patients with no positive test for illicit substances or documentation of prehospital narcotic medications, the pain experience was greater for both, those who had been administered a narcotic in the prehospital setting and those who tested positive for illicit substances. CONCLUSIONS This study extends the concept of total pain experience using AUC methodology. Our results demonstrate associations between increased pain and certain patterns of injury, ages, and presence of drugs on admission. Measuring total pain experience could assist in comparing pain-management strategies. Future research should focus on validating pain experience against quality-of-life measurements.

Barriers to Assessing and Treating Trauma in Primary Care and Opportunities for Improvement: Perspectives from Prescribers of Medications for Opioid Use Disorder. Subst Use Misuse 2023; 58:1651-1659.

Abstract
Background: Medication for Opioid Use Disorder (MOUD) is a best practice for treating individuals with opioid use disorder (OUD), and primary care-based MOUD management can reduce treatment barriers among OUD patients. Individuals with OUD experience disproportionately high rates of trauma and violence, highlighting the importance of addressing trauma, mental health, and substance use concurrently. However, clear guidelines for trauma-informed treatment in a primary care setting remain poorly established. Methods: A qualitative approach was engaged to explore primary care providers' perceptions of barriers and facilitators to assessing and treating trauma among MOUD patients. Twenty in-depth interviews were conducted in 2021 with Baltimore-based MOUD prescribers, including primary care physicians and nurse practitioners. Interview questions assessed experiences with identifying and treating trauma among MOUD patients, including challenges and opportunities. Results: Providers reported extensive histories of trauma experienced by MOUD patients. Barriers to addressing trauma include a lack of standardized protocols/procedures for identifying trauma, insufficient training/time to assess and treat trauma, and the limited availability of external mental health providers and specialty services. Opportunities included building strong, mutually respectful patient-provider relationships, providing individualized, person-centered care, and establishing connections to coordinated multidisciplinary treatment networks. Conclusions: MOUD treatment within primary care is an important way to increase OUD treatment access, but clearer standards are needed for the treatment of trauma within this patient population. These findings demonstrate opportunities to improve standards and systems such that primary care providers are better equipped to assess and treat the complex histories of trauma experienced by individuals with OUD.

Abstract
Although prevalent among people living with human immunodeficiency virus (HIV) (PLWH) and people who use unregulated drugs (PWUD), pain and its possible links to substance use patterns and engagement in HIV treatment remains poorly characterized. We sought to evaluate the prevalence and correlates of pain among a cohort of PLWH who use un-regulated drugs. Between December 2011 and November 2018, 709 participants were recruited, and data were analyzed using generalized linear mixed-effects (GLMM). At baseline, 374 (53 percent) individuals reported moderate-to-extreme pain in the previous 6 months. In a multivariable model, pain was significantly associated with nonmedical prescrip-tion-opioid use (adjusted odds ratio (AOR) = 1.63, 95 percent confidence interval (CI): 1.30-2.05), nonfatal overdose (AOR = 1.46, 95 percent CI: 1.11-1.93), self-managing pain (AOR = 2.25, 95 percent CI: 1.94-2.61), requesting pain medication in the previous 6 months (AOR = 2.01, 95 percent CI: 1.69-2.38), and ever being diagnosed with a mental illness (AOR = 1.47, 95 percent CI: 1.11-1.94). Establishing accessible pain management interventions that address the complex intersection of pain, drug use, and HIV-infection has potential to improve quality of life outcomes among this population.

Systematic Review and Meta-Analysis of the Prevalence of Chronic Pain Among Patients With Opioid Use Disorder and Receiving Opioid Substitution Therapy. THE JOURNAL OF PAIN 2023; 24:192-203. [PMID: 36220483 DOI: 10.1016/j.jpain.2022.08.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 08/26/2022] [Accepted: 08/29/2022] [Indexed: 11/08/2022]
Abstract
To assess studies examining the prevalence of chronic pain (CP) in patients treated with Opioid Substitution Treatment (OST - buprenorphine or methadone) for Opioid Used Disorder (OUD), we conducted a systematic review and meta-analysis of the literature between the years 2000 and 2020. We searched EMBASE, PsycINFO, Cochrane, and MEDLINE databases and included studies assessing the prevalence of CP in OUD adults treated with OST. The studies were assessed for risk of bias and overall quality and the results were pooled using a random-effects model. Subgroup analyses and meta-regressions were used to identify possible factors associated with CP. Twenty-three studies reported data on the prevalence of CP in patients treated with OST were evaluated. The prevalence obtained was 45.3% (CI95% [38.7; 52.1]). Overall, 78.3% of the studies had a low risk of bias. Subgroup analysis estimates did not vary according to gender, OST, and CP duration. However, it appeared that the clinical settings was associated with a lower CP prevalence when assessed in primary care sites. Our study provided an estimate regarding the prevalence of CP among OST patients. These patients deserve specific attention from health professionals and health authorities. Thus, the real challenge in OST patients is the implementation of a multidisciplinary approach to manage CP. PERSPECTIVE: Our meta-analysis provided an estimate of CP prevalence, reaching almost 50% of OUD patients with OST. Thus, the urgent challenge in OST patients is to pay systematic attention to chronic pain diagnosis, along with the implementation of a multidisciplinary patient-focused approach for an appropriate management of CP.

Abstract
PURPOSE A multidisciplinary approach is recommended for patients with complex chronic pain (CP). Many multidisciplinary pain treatment facilities (MTPFs) use patient exclusion criteria but little is known about their characteristics. The objective of this study was to describe the frequency and characteristics of exclusion criteria in public Canadian MTPFs. METHODS We conducted a cross-sectional study in which we defined an MPTF as a clinic staffed with professionals from three disciplines or more (including at least one medical specialty) and whose services were integrated within the facility. We disseminated a web-based questionnaire in 2017-2018 to the administrative leads of MPTFs across the country. They were invited to complete the questionnaire about the characteristics of their facilities. Data were analyzed using descriptive statistics and correlation measures. RESULTS A total of 87 MTPFs were included in the analyses. Half of them (52%) reported using three exclusion criteria or more. There was no significant association between the number of exclusion criteria and wait time for a first appointment or number of new consultations in the past year. Fibromyalgia and migraine were the most frequently excluded pain syndromes (10% and 7% of MPTFs, respectively). More than one MPTF out of four excluded patients with mental health disorders (30%) and/or substance use disorders (29%), including MPTFs with specialists in their staff. CONCLUSIONS Multidisciplinary pain treatment facility exclusion criteria are most likely to affect CP patients living with complex pain issues and psychosocial vulnerabilities. Policy efforts are needed to support Canadian MPTFs in contributing to equitable access to pain management.

Abstract
Background: The opioid overdose epidemic has led health care providers to increased vigilance for opioid-related risks in the treatment of chronic non-cancer pain (CNCP). Media have conveyed stigmatizing representations of opioid analgesics. Aims: This study aimed to understand how the opioid overdose epidemic has impacted health care experiences among people living with CNCP in two Canadian provinces (British Columbia, Quebec). Methods: This qualitative study proceeded through 22 semi-structured interviews conducted in 2019. Participants were recruited from a cross-sectional survey examining the effects of the opioid overdose epidemic on individuals with CNCP. We collected in-depth narratives that we analyzed using a thematic framework. The sample included 12 women and 10 men aged 20 to 70 years, with 11 from each province. Results: Several participants described increased difficulty in accessing medical services for pain since the onset of the opioid overdose epidemic. They reported that some physicians urged them to taper opioids regardless of their pain severity and functional limitations. Some participants reported facing discrimination and care denials as they were labeled "drug-seeking," especially in hospital. Depending on their educational resources, they were unequally able to counter providers' stigmatizing behaviors. However, participants described empathetic relationships with providers with whom they had a long-term relationship. Some participants drew distinctions between themselves and the stigmatized status of "addict" in ways that reinforced stigma toward people who are dependent on opioids. Conclusions: Health policies and provider education programs aimed at reducing opioid-related stigma are needed to counter detrimental consequences of the opioid overdose epidemic for people living with CNCP.

Factors associated with health-related cannabis use intentions among a community sample of people who inject drugs in Los Angeles and San Francisco, CA 2016 to 2018. Drug Alcohol Depend 2021; 219:108421. [PMID: 33301996 PMCID: PMC7856255 DOI: 10.1016/j.drugalcdep.2020.108421] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 11/10/2020] [Accepted: 11/11/2020] [Indexed: 12/23/2022]
Abstract
OBJECTIVE Cannabis motivations have been studied extensively among patients of medicinal cannabis dispensaries, but less is known about motivations in community samples of opioid-using people who inject drugs. Our objective is to describe cannabis use motivations associated with self-treatment of physical pain, emotional issues, and as an opioid substitute. METHODS Data come from 6-month follow-up interviews with people who inject drugs who participated in a study on the efficacy of an injection initiation prevention intervention in Los Angeles and San Francisco, California from 2016-18. The analytic sample consists of 387 people who inject drugs who reported past-month cannabis use. We developed multivariable logistic regression models by reported cannabis use motivations: physical pain relief, emotional problems, and opioid substitute. RESULTS The most common cannabis use motivations reported by people who inject drugs was to "get high," relieve physical pain and emotional problems, and reduce opioid use. In separate multivariate models, using cannabis for physical pain relief was associated with higher odds of using cannabis as a substitute for opioids; cannabis for emotional problems was associated with being diagnosed with depression; and cannabis as a substitute for opioids was associated with non-prescribed, non-injection methadone use. CONCLUSION People who inject drugs reported using cannabis for health-related motivations. This motivation aligns with health needs and suggests the acceptability of cannabis use for health reasons in this population. Studies to determine the medical effectiveness of cannabis products for these common health and mental health needs among people who inject drugs are needed.

Abstract
INTRODUCTION Most studies on chronic noncancer pain (CNCP) in people who use drugs (PWUD) are restricted to people attending substance use disorder treatment programs. This study assessed the prevalence of CNCP in a community-based sample of PWUD, identified factors associated with pain, and documented strategies used for pain relief. METHODS This was a cross-sectional study nested in an ongoing cohort of PWUD in Montreal, Canada. Questionnaires were administered to PWUD seen between February 2017 and January 2018. CNCP was defined as pain lasting three or more months and not associated with cancer. RESULTS A total of 417 PWUD were included (mean age = 44.6 ± 10.6 years, 84% men). The prevalence of CNCP was 44.8%, and the median pain duration (interquartile range) was 12 (5-18) years. The presence of CNCP was associated with older age (>45 years old; odds ratio [OR] = 1.8, 95% CI = 1.2-2.7), male sex (OR = 2.3, 95% CI = 1.2-4.2), poor health condition (OR = 1.9, 95% CI = 1.3-3.0), moderate to severe psychological distress (OR = 2.9, 95% CI = 1.8-4.7), and less frequent cocaine use (OR = 0.5, 95% CI = 0.3-0.9). Among CNCP participants, 20.3% used pain medication from other people, whereas 22.5% used alcohol, cannabis, or illicit drugs to relieve pain. Among those who asked for pain medication (N = 24), 29.2% faced a refusal from the doctor. CONCLUSIONS CNCP was common among PWUD, and a good proportion of them used substances other than prescribed pain medication to relieve pain. Close collaboration of pain and addiction specialists as well as better pain assessment and access to nonpharmacological treatments could improve pain management in PWUD.

Abstract
OBJECTIVE High levels of chronic pain interference with daily activities are known to negatively impact quality of life. Although mental health conditions have been associated with pain interference and child abuse, research has been mixed regarding it acting as a mediator, with even less known among people who inject drugs. Therefore, we sought to explore childhood emotional abuse and pain interference among this population. METHODS Data were derived from two prospective cohort studies of community-recruited people who inject drugs in Vancouver, Canada, between June 2014 and November 2016. We employed multivariable generalized estimating equations to examine the relationship between childhood emotional abuse and pain interference in the past six months. We also conducted a mediation analysis to examine whether mental health disorder diagnoses mediated this association. RESULTS Among 822 eligible participants, 341 (41.5%) reported childhood emotional abuse. In a multivariable analysis, experiencing childhood emotional abuse remained independently associated with pain interference (adjusted odds ratio = 1.33, 95% confidence interval [CI] = 1.05-1.70) after adjusting for a range of confounders. Results from the mediation analysis yielded a statistically significant positive average causal mediation effect (β = 0.01, 95% CI = 0.001-0.02). Approximately 12% of the effect was due to mediation. CONCLUSIONS Our results demonstrate among people who inject drugs with chronic pain, those who experienced childhood emotional abuse were more likely to report pain interference, which was partially mediated by mental health disorder diagnosis history. These findings highlight the importance of incorporating screening and appropriate treatment for mental illness into chronic pain treatment.

Abstract
BACKGROUND Chronic non-cancer pain (CNCP) among patients with substance use disorder (SUD) poses a risk for worse treatment outcomes. Understanding the association of CNCP with SUD is important for informing the need and potential benefits of pain assessment/management among those with SUDs. METHODS We analyzed electronic health record data from 2013 to 2018 among adults aged ≥18 years (N = 951,533; mean age: 48.4 years; 57.4 % female) in a large academic healthcare system. Adjusted logistic regression models were conducted to estimate the association of CNCP conditions with opioid overdose, emergency department utilization, and inpatient hospitalization stratified by different SUD diagnoses and by gender. RESULTS Among the total sample, the prevalence of CNCP was 46.6 % and any SUD was 11.2 %. The majority of patients with a SUD had CNCP (opioid: 74.7 %; sedative: 72.3 %; cannabis: 64.3 %; alcohol: 58.7 %; tobacco: 59.5 %). The prevalence of CNCP was greater in females vs. males for most SUD diagnoses. The presence of CNCP was associated with more mental health disorders and chronic medical conditions among each SUD group. CNCP was associated with significantly decreased odds of overdose among those with opioid use disorder but increased odds of overdose and healthcare utilization among other SUDs. CNCP was positively associated with overdose in females, but not males, with alcohol or non-opioid drug use disorders. CONCLUSIONS The direction and magnitude of the association between CNCP and negative health indicators differed as a function of SUD type and gender, respectively. Greater awareness of potential unmet pain treatment need may have implications for improving SUD outcomes.

Abstract
INTRODUCTION AND AIMS People who inject drugs (PWID) are a key group within the hepatitis C virus (HCV) pandemic. Chronic pain is a common condition among PWID as these individuals are often exposed to soft tissue infections due to injections and violence. This study aims to characterise the relationship between HCV exposure and pain among PWID. DESIGN AND METHODS Data were derived from three prospective cohorts of PWID in Vancouver, Canada, between December 2011 and November 2016. The primary outcome was pain severity, which was defined based on the Euroqol EQ-5D-3L pain subscale. A bivariable and multivariable ordinal generalised estimating equations model was used to quantify the association between HCV exposure and pain among participants. RESULTS One thousand and twelve of 2038 participants (50%) reported moderate/extreme pain at baseline. In total, 1473 (72%) participants were HCV-antibody positive. In unadjusted analyses, HCV exposure was positively associated with increased pain [odds ratio (OR) = 1.47; 95% confidence interval (CI): 1.20-1.81]. However, once adjusted for known confounders in multivariable analyses, HCV exposure did not remain significantly associated with increased pain (adjusted OR = 1.00; 95%CI: 0.78-1.28). DISCUSSION AND CONCLUSIONS In this sample of PWID, HCV exposure was not significantly associated with pain once other factors were considered. These various factors may explain the elevated risk of pain among PWID and should be addressed in future initiatives when managing pain among PWID with HCV exposure. Future studies should also examine whether pain changes with changes in HCV status (i.e. active vs. cleared infection).

Abstract
The current opioid crisis in the United States has emerged from higher demand for and prescribing of opioids as chronic pain medication, leading to massive diversion into illicit markets. A peculiar tragedy is that many health professionals prescribed opioids in a misguided response to legitimate concerns that pain was undertreated. The crisis grew not only from overprescribing, but also from other sources, including insufficient research into nonopioid pain management, ethical lapses in corporate marketing, historical stigmas directed against people who use drugs, and failures to deploy evidence-based therapies for opioid addiction and to comprehend the limitations of supply-side regulatory approaches. Restricting opioid prescribing perversely accelerated narco-trafficking of heroin and fentanyl with consequent increases in opioid overdose mortality As injection replaced oral consumption, outbreaks of hepatitis B and C virus and human immunodeficiency virus infections have resulted. This viewpoint explores the origins of the crisis and directions needed for effective mitigation.

Abstract
BACKGROUND People who inject drugs (PWID) often contend with chronic pain as a result of illness and trauma, and such pain is known to have significant impacts on mental health, quality of life, and substance use behaviours. Although PWID are also known to have high rates of childhood trauma, little is known about how childhood emotional abuse may be associated with chronic pain in this population. OBJECTIVE We undertook this study to explore emotional abuse and chronic pain among PWID. PARTICIPANTS AND SETTING This study comprised a total of 1459 participants in Vancouver, Canada between June 2014 and November 2016. METHODS We employed multivariable generalized estimating equations with data derived from two prospective cohort studies of community-recruited PWID to examine the relationship between childhood emotional abuse and chronic pain in the past six months. RESULTS Among eligible participants, 591 (40.5%) reported childhood emotional abuse, and 760 (52.1%) reported chronic pain in the previous six months. In a multivariable analysis, experiencing childhood emotional abuse remained independently associated with chronic pain (adjusted odds ratio: 1.25; 95% confidence interval: 1.01-1.53) after adjustment for a range of socio-demographic and drug use confounders. CONCLUSIONS Our findings suggest that childhood emotional abuse may have lasting relationships with chronic pain among PWID, potentially through established physiological and psychological mechanisms. Current chronic pain treatment may benefit from the evaluation of life course vulnerabilities that may be amenable to earlier interventions. Further, increased availability of effective trauma-informed chronic pain treatment is needed among this vulnerable population.

Abstract
PURPOSE OF REVIEW To explore the consequences of policies implemented in the Russian Federation in response to syndemic of HIV-1 and opioid use disorder and compare the responses to the concomitant syndemic in rural America. RECENT FINDINGS The syndemic spread has not been reduced by policies implemented by the Russian government, which continues to underfund harm reduction efforts to reduce HIV transmission, refuses to approve evidence-based opioid agonist treatments for opioid use disorder, and relies on criminal justice and abstinence approaches to control illicit opioids. When effective measures have been undertaken locally, the lessons learned have not been transferred to other parts of the country and local programs have been allowed to wither. As in many parts of rural America, Russia has experienced intertwined epidemics of opioid misuse and HIV-1 that continue to expand. The expansion has been facilitated by adoption of policies that run contrary to medical and public health evidence.

Abstract
BACKGROUND In Canada, the rise in prescription opioid (PO) overdoses and addiction is a major public health concern. Various health authorities have recently recommended that physicians use caution when prescribing opioids, especially to people with histories of substance use. As a result, fewer therapeutic options are available for people who use drugs (PWUD) and suffer from chronic non-cancer pain (CNCP). This paper examines how PWUD describe their experiences with CNCP management in the context of the opioid crisis. METHODS This qualitative study is based on in-depth interviews with Montreal (Canada) PWUD experiencing CNCP for 3 months or more. RESULTS Most of the 25 participants (27-61 years; 10 women, 15 men) were polysubstance users (cocaine, opioids, amphetamine, etc.) suffering from CNCP for several years, with multiple additional health and social problems. The majority were unsatisfied with their CNCP management. They felt labelled as "addicts" and stigmatized within the healthcare system. Many participants had been denied PO, even those with severe CNCP and those who were not opioid-dependent. Participants expressed a desire to access non-pharmacological CNCP therapies, but these were often too expensive. Some PWUD were offered methadone to relieve CNCP and found this inappropriate. As a last resort several participants reported self-medicating CNCP with street drugs, increasingly known to be laced with fentanyl. CONCLUSION PWUD with CNCP are affected by two opioid crises: the PO crisis and the street-opioid crisis. The lack of a coherent policy that addresses their pain management produces reoccurring problems when seeking CNCP relief. Restrictive prescription measures implemented in response to the PO crisis may have consequences similar to prohibitionist policies: they heighten overdose risks for PWUD by increasing exposure to street drugs laced with fentanyl. Improving access to diverse CNCP management options for PWUD can help reduce harms related to street-opioid use.

Abstract
The current opioid crisis highlights an urgent need for better paradigms for prevention and treatment of chronic pain and addiction. Although many approach this complex clinical condition with the question, "Is this pain or is this addiction?," it is more than the sum of its parts. Chronic pain among those with dependence and addiction often evolves into a complex disabling condition with pain at multiple sites, psychosocial dysfunctions, medical and psychiatric disorders, polypharmacy, and polysubstance use, all interacting with each other in complex ways (multimorbidity). The authors offer an integrative therapeutic approach to manage this complex clinical scenario.

Abstract
Opioid overdose and substance abuse treatment entry data suggest that injection drug use is increasing in nonurban locations. We sought to explore the prevalence and incidence of viral infections among people who inject drugs (PWID) residing in Fairfield and New Haven counties but outside of the six largest cities. A longitudinal cohort of PWID was assembled and incidence of HIV-1, hepatitis B virus, and hepatitis C virus infections was determined by annual antibody screening. Data on participants' socioeconomic situation and risk behaviors were collected. We identified 11 new hepatitis C virus infections and calculated incidence at 9.03 cases per 100 person-years. Only one new HIV infection and one new hepatitis B virus infection were detected. Factors associated with seroconversion were assessed. Given the high incidence of HCV and lack of HBV vaccination coverage, prevention and treatment resources need to be targeted to this population.

Abstract
Individuals experiencing homelessness in the United States are aging; little is known about chronic pain in this population. In a cross-sectional, population-based study, we interviewed 350 homeless individuals aged 50 years and older to describe pain experienced by older persons experiencing homelessness and to assess factors associated with chronic moderate to severe pain, defined as pain lasting ≥3 months, with a past week average severity score of 5 to 10 (scale 0-10). The median age of participants was 58 years. Participants were predominantly African American (79.6%) and male (77.3%). Overall, 46.8% reported chronic moderate to severe pain. Almost half of participants reported a diagnosis of arthritis (44.3%) and one-third reported symptoms consistent with post-traumatic stress disorder (PTSD; 32.8%). Three-quarters (75.3%) endorsed a personal history of abuse. In multivariate analyses, PTSD (adjusted odds ratio [AOR]: 2.2, 95% confidence interval [CI], 1.4-3.7), arthritis (AOR: 4.8, 95% CI, 3.0-7.8), and history of experiencing abuse (AOR: 2.4, 95% CI, 1.3-4.3) were associated with chronic moderate to severe pain. HIV status, diabetes, depressive symptoms, and substance use were not associated with pain. Clinicians should consider the management of associated mental health conditions and the sequelae of experiencing abuse in the treatment of chronic pain in older adults experiencing homelessness. PERSPECTIVE This article describes the prevalence and factors associated with chronic pain in older homeless adults. Almost half report chronic pain, which was associated with PTSD, arthritis, and personal history of abuse. Clinicians should address chronic pain, trauma, and the associated mental health conditions in this high-risk population.

Abstract
Background People who inject drugs (PWID) often have poor health and lack access to health care. The aim of this study was to examine whether PWID engage in self-treatment through nonmedical prescription opioid use (NMPOU). We describe the prevalence and features of self-reported physical pain and its association with NMPOU. Methods PWID (N = 702) in San Francisco, California (age 18+) were recruited to complete interviewer administered surveys between 2011 and 2013. Multivariate logistic regression analysis was conducted to examine the associations among self-reported pain dimensions (past 24-h average pain, pain interference with functional domains) and NMPOU, controlling for age, sex, psychiatric illness, opioid substitution treatment, homelessness, street heroin use and unmet healthcare needs. Results Almost half of the sample reported pain, based on self-reported measures in the 24 h before their interview. The most common pain locations were to their back and lower extremities. Past 24-h NMPOU was common (14.7%) and associated with past 24 h average pain intensity on a 10 point self-rating scale (adjusted odds ratio [AOR] = 2.15, 95% confidence interval [CI] 1.21–3.80), and past 24 h pain interference with general activity (AOR 1.82 [95% CI 1.04–3.21]), walking ability (AOR 2.52 [95% CI 1.37–4.63]), physical ability (AOR 2.01 [95% CI 1.16–3.45]), sleep (AOR 1.98 [95% CI 1.13–3.48]) and enjoyment of life (AOR 1.79 [95% CI 1.02–3.15]). Conclusion Both pain and NMPOU are common among PWID, and highly correlated in this study. These findings suggest that greater efforts are needed to direct preventive health and services toward this population.

Mu Opioid Receptor Modulation of Dopamine Neurons in the Periaqueductal Gray/Dorsal Raphe: A Role in Regulation of Pain. Neuropsychopharmacology 2016; 41:2122-32. [PMID: 26792442 PMCID: PMC4908643 DOI: 10.1038/npp.2016.12] [Citation(s) in RCA: 100] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2015] [Revised: 01/08/2016] [Accepted: 01/08/2016] [Indexed: 12/14/2022]
Abstract
The periaqueductal gray (PAG) is a brain region involved in nociception modulation, and an important relay center for the descending nociceptive pathway through the rostral ventral lateral medulla. Given the dense expression of mu opioid receptors and the role of dopamine in pain, the recently characterized dopamine neurons in the ventral PAG (vPAG)/dorsal raphe (DR) region are a potentially critical site for the antinociceptive actions of opioids. The objectives of this study were to (1) evaluate synaptic modulation of the vPAG/DR dopamine neurons by mu opioid receptors and to (2) dissect the anatomy and neurochemistry of these neurons, in order to assess the downstream loci and functions of their activation. Using a mouse line that expresses eGFP under control of the tyrosine hydroxylase (TH) promoter, we found that mu opioid receptor activation led to a decrease in inhibitory inputs onto the vPAG/DR dopamine neurons. Furthermore, combining immunohistochemistry, optogenetics, electrophysiology, and fast-scan cyclic voltammetry in a TH-cre mouse line, we demonstrated that these neurons also express the vesicular glutamate type 2 transporter and co-release dopamine and glutamate in a major downstream projection structure-the bed nucleus of the stria terminalis. Finally, activation of TH-positive neurons in the vPAG/DR using Gq designer receptors exclusively activated by designer drugs displayed a supraspinal, but not spinal, antinociceptive effect. These results indicate that vPAG/DR dopamine neurons likely play a key role in opiate antinociception, potentially via the activation of downstream structures through dopamine and glutamate release.

Abstract
OBJECTIVES Studies from pain treatment settings indicate that poor acceptance of pain may be an important and modifiable risk factor for higher severity of opioid use. However, the degree to which pain acceptance relates to opioid use severity in the addiction treatment population is unknown. In this study of addiction treatment patients with co-morbid pain, we examined correlates of severity of opiate (heroin and prescription opioid) use, with a particular focus on the role of pain acceptance. METHODS Patients in residential addiction treatment with comorbid pain (N=501) were stratified into low, moderate and high severity of opiate use. Demographic and clinical characteristics were compared across opiate severity categories. RESULTS 72% (N=360) of the participants had symptoms that were consistent with an opiate use disorder. Younger age, Caucasian race, female gender, cocaine use and lower pain acceptance were associated with higher severity of opiate use, whereas pain intensity was not. Controlling for demographic and other risk factors, such as substance use and pain intensity, higher pain acceptance was associated with lower odds of severe prescription opioid (AOR 0.50, 95% CI 0.38-0.68 for a one SD increase in pain acceptance) and heroin use (AOR 0.57, 95% CI 0.44-0.75 for a one SD increase in pain acceptance). CONCLUSIONS Problematic opiate use is common in addictions treatment patients with chronic pain. Lower pain acceptance is related to greater opiate use severity, and may be an important modifiable target for interventions to successfully treat both pain and opiate use disorders.
