Pisl V, Vevera J. COVID-19 vaccine uptake in mental healthcare users: Czech nationwide register study. Vaccine 2023; 41:5435-5440. [PMID: 37479611 DOI: 10.1016/j.vaccine.2023.07.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/10/2023] [Accepted: 07/12/2023] [Indexed: 07/23/2023]
Abstract
BACKGROUND The excessive covid-related mortality of psychiatric patients was reduced by vaccination. The vaccine uptake in patients diagnosed with different mental health disorders is, however, not fully described. AIMS A nationwide, record-based retrospective cross-sectional study examines the effect of substance use, psychotic, affective, anxiety, and personality disorders on COVID-19 vaccination rates in August and December 2021. Further, it quantifies the effect of receiving mental healthcare on vaccine uptake. METHODS The COVID-19 vaccine rates of mental healthcare users in August and December 2021 were examined using logistic regression models adjusted for sex and age on a sample of 7,235,690 adult inhabitants of the Czech Republic. The probability of vaccine uptake in the week following mental healthcare appointment or hospitalization on any day in the fall 2021 was compared to the general probability of getting vaccinated during that week. RESULTS The vaccination rate in August 2021 was related to history of hospitalization due to substance use (OR = 0.71), personality (OR = 0.87), psychotic (OR = 0.92), and anxiety (OR = 1.15) disorders, while mood disorders had no effect (OR = 1.00). Compared to general population, mental healthcare users were undervaccinated in August but not in December 2021. Vaccine uptake was low in those with history of psychiatric hospitalizations but higher in those utilizing inpatient or outpatient mental healthcare recently, predominantly for affective disorders. Increased vaccine uptake was observed following utilization of mental healthcare as well as in those with repeated psychiatric hospitalizations. CONCLUSIONS The vaccination rates of mental healthcare users relative to general population largely differ across nosological categories and during the vaccination campaign. Psychiatrists were successful in promoting vaccination against COVID-19.

Incidence and Determinants of COVID-19 in Patients Seeking Treatment for Substance Use Disorder: A Patient-Based Linkage Study. Eur Addict Res 2023; 29:333-343. [PMID: 37586329 PMCID: PMC10614235 DOI: 10.1159/000528647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 12/05/2022] [Indexed: 08/18/2023]
Abstract
INTRODUCTION People with substance use disorder (SUD) may be at increased risk of COVID-19 infection. However, there is little evidence regarding the incidence of and determinants associated with infection in this group. The aims of the study were to determine the cumulative incidence of COVID-19 among people who sought treatment for heroin, cocaine, cannabis, and alcohol use disorder in Catalonia; to identify sociodemographic, substance, and clinical determinants associated with COVID-19 infection among SUD patients; and to compare the cumulative incidence of COVID-19 infection in the population with SUD with that of the general population. METHODS A patient-based retrospective observational study was conducted. The study population comprised people who sought treatment for heroin, cocaine, cannabis, or alcohol use disorder in Catalonia in 2018 and 2019. We analysed cumulative incidence of COVID-19 (confirmed by PCR test) from 25 February to 31 December 2020. Additionally, we used a log-link binomial generalized linear model for COVID-19 infection, using the substance as the exposition, adjusting for sociodemographic and clinical variables. RESULTS Of the 23,092 individuals who sought treatment for SUD, 38.15% were considered suspected cases of COVID-19, and 2.60% (95% CI = 2.41-2.82) were confirmed positive for COVID-19 by PCR test during the study period. Those who sought treatment for alcohol use (cumulative incidence of COVID-19 of 3% [95% CI = 2.70-3.34]) had a higher risk ratio than, those who sought treatment for heroin use (cumulative incidence of 1.94% [95% CI = 1.47-2.56]). Being born outside of Spain, living in an institutionalized residence, having HIV, and being in a high morbidity group were associated with higher risk of COVID-19 infection. Meanwhile, the cumulative incidence of COVID-19 in the general population, according to public COVID-19 test data, was 3.86% (95% CI = 3.85-3.87). CONCLUSION This study did not find higher cumulative incidence of COVID-19 infection among people with SUD in Catalonia in 2020, despite the clinical vulnerability of this population and their social disadvantage. However, differences were seen in the cumulative incidence of COVID-19 according to the substance for which treatment was sought. For example, those with alcohol dependence had a higher rate than those dependent on heroin. Further studies are needed to determine the factors contributing to these differences.

Abstract
BACKGROUND The impact of illicit substance use is especially devastating in low-resourced countries where factors such as poverty, unemployment, and inadequate services impede successful treatment. Contingency management (CM) is a treatment for substance use disorders that has shown to be effective in eliciting behaviour change. The efficacy of CM interventions in low and middle income countries (LMICs) has been under explored. METHODS The aim of this systematic review of randomized controlled trials was to assess measures of CM efficacy in addressing substance use disorders, while also considering contextual moderators of CM in LMICs. A search of PubMed, Scopus, and Cochrane library databases yielded 18 studies for inclusion, from which relevant data were extracted using modified versions of the Cochrane Characteristics of Studies tool. RESULTS Two studies were located in a low-income country, two in lower-middle income countries, and fourteen in upper middle-income countries. Overall, estimated efficacy estimates were similar to those from higher income countries. However, context-specific challenges that warrant further investigation included limited access to trained staff and structural and financial constraints. CONCLUSIONS While CM in LMICs is in its early stages of development, efficacy estimates were not substantially different compared to high income countries. Challenges such as costs, willingness to implement, and the stigma associated with addiction sets the stage for further research in these contexts.

Abstract
Background Scant information exists on Iranian women's protective behaviors mainly constant condom use. Inconsistent condom use seems prevalent among women with substance use problems. We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian women with substance use disorders (SUDs). Methods In our cross-sectional study, we recruited 300 women who sought treatments for their SUDs from the active outpatient drug free (ODF) and Methadone Maintenance Therapy (MMT) centers in Tehran, Iran during 2017-2021. We used three batteries including demographic questionnaire, the Risky Sexual Behavior Questionnaire (RSBQ); and the Condom Barriers Scale (CBS). The statistical software R, analysis of variance post hoc and multivariate analysis of variance (MANOVA) logistic regression tests were used in data analysis. Results The majority reported at least one lifetime experience of RSBs. Our results show that only 22% of the participants 'always' use condom in their sexual encounters. The lowest and highest subscale scores of the CBS were related to Sexual Experience (SE) (2.47 ± 0.86) and access/availability structure (3.52 ± 0.7), respectively. RSBs had negative significant association with Partner Barrier (PB) subscale scores (OR = 0.4; 95% CI: 0.22 to 0.73) and effect on SE subscale scores (OR= 0.54; 95% CI: 0.31 to 0.94). Conclusion RSBs was prevalent among our study population. RSBs and condom use barriers are significantly interwoven. The condom use barriers were highly associated with the types of sexual encounters such as group sex or casual sexual relations than specific mean of sexual performance (i.e. anal sex). Gender-specific RSBs, STIs/HIV/AIDS prevention program is recommended for women with SUDs.

Pilot Feasibility Stud 2023; 9:135. [PMID: 37525253 PMCID: PMC10388447 DOI: 10.1186/s40814-023-01361-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 07/10/2023] [Indexed: 08/02/2023] Open
Abstract
BACKGROUND Law enforcement frequently responds to substance abuse and mental health crises. Crisis stabilization units (CSUs) operate as a public-receiving facility to provide short-term stabilization services for individuals experiencing these crises and offer law enforcement an important alternative to arrest. However, there is limited understanding about how and when law enforcement decides to use CSUs. There is also the challenge of retaining individuals in treatment after CSU stabilization to prevent future crises and persistent engagement with police. This study will respond to these gaps by exploring CSU procedures and examining the feasibility and acceptability of a technology-assisted mobile aftercare intervention designed for individuals brought to a CSU by law enforcement. METHODS This study will consist of three aims. Aim 1 will include qualitative interviews with law enforcement and CSU-affiliated mental health staff (n=80) regarding CSU utilization and collaboration logistics between the groups. Findings from Aim 1 will be synthesized for the development of an implementation guide of our intervention, mobile, and technology-assisted aftercare, designed for individuals brought to a CSU by law enforcement, during Aim 2. During Aim 2, intervention services will be pilot-tested for 6 months through a small sample (n=24), randomized control trial (RCT). Control participants will receive standard services available for individuals discharging from a CSU. Treatment participants will receive the mobile aftercare intervention. Qualitative and quantitative data will be collected at 2 weeks, 3 months, and 6 months post-recruitment for all study participants. Aims 1 and 2 will inform the design of a multi-site RCT to compare CSUs with and without mobile and technology-assisted aftercare (Aim 3). DISCUSSION The study will offer decision making and procedural insight into law enforcement use of CSUs as an alternative to jail and provide opportunities to inform that process. This research will provide outcome trends for those who go through standard CSU services compared to those who receive mobile and technology-assisted aftercare services. The current study will inform a larger RCT efficacy study of CSUs with and without technology-assisted aftercare services. TRIAL REGISTRATION This study was registered on ClinicalTrials.gov (reference #NCT04899934) on May 25, 2021.

Abstract
Background: Alterations in EEG activity have been considered valid endophenotypes of substance use disorders (SUDs). Empirical evidence has supported the association between genetic factors (e.g., genes, single nucleotide polymorphisms [SNPs]) and SUDs, considering both clinical samples and individuals with a positive family history of SUDs [F+SUD]). Nevertheless, the relationship between genetic factors and intermediate phenotypes (i.e., altered EEG activity) among individuals with SUD phenotypes remains unclear.Objective(s): The current study aims at summarizing genetic factors linked to aberrant EEG activity among individuals with SUDs and those with F+SUD.Methods: Sixteen studies (5 [N = 986] + 11 from the Collaborative Studies On Genetics of Alcoholism [COGA] sample [432 ≤ N ≤ 8810]) were included for a qualitative systematic review. Thirteen studies (5 + 8 studies from the COGA sample) were used for multi-level meta-analytic procedures.Results: Qualitative analyses highlighted a multivariate genetic architecture linked to alterations in EEG waves among individuals with SUD phenotypes (i.e., augmented resting-state beta waves; reduced resting-state alpha waves; reduced resting-state and task-dependent theta waves). The most recurrent genetic factors were involved in cellular energy homeostasis, modulation of inhibitory and excitatory neural activity together with neural cell growth. Meta-analytic results showed a moderate association between genetic factors and altered resting-state and task-dependent EEG activity. Meta-analytic results also suggested non-additive genetic effects on altered EEG activity.Conclusions: Complex genetic interactions mediating neural activity and brain development might constitute a causal pathway toward intermediate phenotypes associated with phenotypic features, which in turn are linked to SUDs.

Abstract
INTRODUCTION Cannabis is used for medical and recreational purposes and may result in cannabis use disorder (CUD). This study explored the prevalence of cannabis use disorder and other psychiatric comorbidities among inpatients undergoing treatment for substance use disorder who reported medical cannabis use at admission. METHODS We assessed CUD and other substance use disorders based on DSM-5 symptoms, anxiety with the Generalized Anxiety Disorder scale (GAD-7), depression with the Patient Health Questionnaire (PHQ-9), and post-traumatic stress disorder with the PTSD Checklist for DSM-5 (PCL-5). We compared the prevalence of CUD and other psychiatric comorbidities between inpatients who endorsed the use of cannabis for medical purposes only vs those endorsing use for medical and recreational purposes. RESULTS Among 125 inpatients, 42% reported medical use only, and 58% reported medical and recreational use (dual motives). For CUD, 28% of Medical-Only and 51% of Dual-Use motives patients met the diagnostic criteria for CUD (p = 0.016). High psychiatric comorbidities were present: 79% and 81% screened positive for an anxiety disorder, 60% and 61% screened positive for depression, and 66% and 57% screened positive for PTSD for the Medical-Only and Dual-Use inpatients, respectively. CONCLUSIONS Many treatment-seeking individuals with substance use disorder who report medical cannabis use meet criteria for CUD, particularly those reporting concurrent recreational use.

Abstract
We sought to determine common characteristics of SUD-related hospitalizations and patterns of discharge diagnoses among adolescents in the United States. Using the 2016 KID, a cross-sectional study was conducted to identify discharge records associated with ICD-10-CM diagnostic codes for SUD. Adolescents between the ages of 13 and 19 were included. SUD and non-SUD groups were compared using the Student's t-test for continuous variables and the χ2 test for categorical variables. A total of 6.7 million hospital discharges were analyzed. A uniform and a standardized coding system were used to identify cases. Subgroup comparative analysis for length of stay, hospital charge, and common discharge diagnoses was performed. A weighted estimate of 94,732 adolescents associated with SUD was discharged from the U.S. hospitals during the study year. Teens with SUD accounted for 510,268 days of inpatient days in the U.S. community hospitals accounting for a total charge of $3,070,948,580. The average LOS for all SUD teens in the U.S. was 5.4 days with a mean charge per discharge of $32,754, indicating higher LOS but a significantly lower mean charge compared to non-SUD teens (4.1 days; $39,657). In 2016, more than 88% of SUD patients had ≥ 3 diagnoses compared to non-SUD patients (76%) (P < 0.0001 for all). The most frequently observed diagnosis associated with teens with SUD was psychoses, depressive neuroses, and alcohol use disorder. With one in ten teenagers found with an SUD, early substance initiation still appears to be an important public health issue. Unfortunately, the health and economic impact of substance use in adolescence on society are huge requiring effective strategies targeted to this population. The concerning data and literature identify a significant need to address prevention, treatment, and recovery services for adolescents throughout the United States.

Abstract
RATIONALE Cocaine can increase inflammatory neuroimmune markers, including chemokines and cytokines characteristic of innate inflammatory responding. Prior work indicates that the Toll-like receptor 4 (TLR4) initiates this response, and administration of TLR4 antagonists provides mixed evidence that TLR4 contributes to cocaine reward and reinforcement. OBJECTIVE These studies utilize (+)-naltrexone, the TLR4 antagonist, and mu-opioid inactive enantiomer to examine the role of TLR4 on cocaine self-administration and cocaine seeking in rats. METHODS (+)-Naltrexone was continuously administered via an osmotic mini-pump during the acquisition or maintenance of cocaine self-administration. The motivation to acquire cocaine was assessed using a progressive ratio schedule following either continuous and acute (+)-naltrexone administration. The effects of (+)-naltrexone on cocaine seeking were assessed using both a cue craving model and a drug-primed reinstatement model. The highly selective TLR4 antagonist, lipopolysaccharide from Rhodobacter sphaeroides (LPS-Rs), was administered into the nucleus accumbens to determine the effectiveness of TLR4 blockade on cocaine-primed reinstatement. RESULTS (+)-Naltrexone administration did not alter the acquisition or maintenance of cocaine self-administration. Similarly, (+)-naltrexone was ineffective at altering the progressive ratio responding. Continuous administration of (+)-naltrexone during forced abstinence did not impact cued cocaine seeking. Acute systemic administration of (+)-naltrexone dose-dependently decreased cocaine-primed reinstatement of previously extinguished cocaine seeking, and administration of LPS-Rs into the nucleus accumbens shell also reduced cocaine-primed reinstatement of cocaine seeking. DISCUSSION These results complement previous studies suggesting that the TLR4 plays a role in cocaine-primed reinstatement of cocaine seeking, but may have a more limited role in cocaine reinforcement.

Abstract
The Supreme Court's ruling to overturn the 1973 Roe v. Wade verdict represents a major setback for women's reproductive freedoms in the United States. This ruling revokes constitutional protection for abortion rights and returns the decision to the states. Since this ruling in June 2022, numerous states have adopted total or near total abortion bans, with many of these bans offering no exception for rape, incest, or nonfatal maternal health risks. Legal experts also warn that this ruling can open the door to restrict contraceptive rights previously protected under the same implied constitutional right to privacy as abortion. Already, this decision has increased momentum for states to place restrictions on specific forms of contraception. Certain groups of women will be disproportionately harmed by these bans, such as women with substance use disorders (SUDs). Women with SUDs face unique barriers to sexual and reproductive health services that exist at the structural level (e.g., criminalization; costs and accessibility), interpersonal level (e.g., higher rates of intimate partner violence) and individual level (e.g., reduced reproductive autonomy). These synergistic barriers interact to produce lower contraceptive use, increased unintended pregnancy rates, and subsequently a greater need for abortion services among this population. This ruling will exacerbate the effects of these barriers on women with SUDs, resulting in even greater difficulties accessing contraceptive and abortion services, and ultimately increasing rates of criminalization among pregnant and parenting women with SUDs. This commentary describes these barriers and highlights potential advocacy steps that are urgently needed to assist reproductive-aged women with SUDs during these challenging times when essential health services are increasingly inaccessible.

Abstract
Substance use disorders (SUD) are associated with increased risk of worse COVID-19 outcomes. Likewise, racial/ethnic minority patients experience greater risk of severe COVID-19 disease compared to white patients. Providers should understand the role of race and ethnicity as an effect modifier on COVID-19 severity among individuals with SUD. This retrospective cohort study assessed patient race/ethnicity as an effect modifier of the risk of severe COVID-19 disease among patients with histories of SUD and overdose. We used merged electronic health record data from 116,471 adult patients with a COVID-19 encounter between March 2020 and February 2021 across five healthcare systems in New York City. Exposures were patient histories of SUD and overdose. Outcomes were risk of COVID-19 hospitalization and subsequent COVID-19-related ventilation, acute kidney failure, sepsis, and mortality. Risk factors included patient age, sex, and race/ethnicity, as well as medical comorbidities associated with COVID-19 severity. We tested for interaction between SUD and patient race/ethnicity on COVID-19 outcomes. Findings showed that Non-Hispanic Black, Hispanic/Latino, and Asian/Pacific Islander patients experienced a higher prevalence of all adverse COVID-19 outcomes compared to non-Hispanic white patients. Past-year alcohol (OR 1.24 [1.01-1.53]) and opioid use disorders (OR 1.91 [1.46-2.49]), as well as overdose history (OR 4.45 [3.62-5.46]), were predictive of COVID-19 mortality, as well as other adverse COVID-19 outcomes. Among patients with SUD, significant differences in outcome risk were detected between patients of different race/ethnicity groups. Findings indicate that providers should consider multiple dimensions of vulnerability to adequately manage COVID-19 disease among populations with SUDs.

Abstract
BACKGROUND The selection of appropriate efficacy endpoints in clinical trials has been a long-standing challenge for the substance use disorder field. Using data from a large, multi-site National Drug Abuse Treatment Clinical Trials Network trial (CTN-0044; n=474), this secondary data analysis aimed to explore whether specific proximal (during-treatment) substance use outcome measures predict longer-term improvements in psychosocial functioning and post-treatment abstinence, and whether predictions vary depending on the specific substance (cannabis, cocaine/stimulants, opioids, and alcohol). METHODS Generalized linear mixed models examined associations between six during-treatment substance use outcome measures and social functioning impairment (Social Adjustment Scale Self-Report) and severity of psychiatric symptoms (Brief Symptom Inventory-18) at end-of-treatment, and 3- and 6-months after treatment as well as post-treatment abstinence. RESULTS Maximum days of consecutive abstinence, proportion of days abstinent, ≥3 weeks of continuous abstinence, and the proportion of urine specimens negative for the primary substance were associated with post-treatment psychiatric and social functioning improvement and abstinence. However, only the effects of abstinence during the last 4 weeks of the treatment period on all three post-treatment outcomes was stable over time and did not differ between primary substance groups. In contrast, complete abstinence during the 12-week treatment period was not consistently associated with functioning improvements. CONCLUSIONS Substance use outcome measures capturing the duration of primary substance abstinence during treatment are suitable predictors of post-treatment abstinence and longer-term psychosocial functioning improvement. Binary outcomes, such as end-of-treatment abstinence, may be particularly stable predictors and attractive given their ease of computation and straightforward clinical interpretability.

Abstract
BACKGROUND A large proportion of adult psychiatric inpatients experience homelessness and are often discharged to unstable accommodation or the street. It is unclear whether homelessness impacts psychiatric hospital readmission. Our primary objective was to examine the association between homelessness and risk for 30-day and 90-day readmission following discharge from a psychiatric unit at a single urban hospital. METHODS A retrospective cohort study involving health administrative data among individuals (n = 3907) in Vancouver, Canada with an acute psychiatric admission between January 2016 and December 2020. Participants were followed from the date of index admission until censoring (December 30, 2020). Homelessness was measured at index admission and treated as a time-varying exposure. Adjusted Hazard Ratios (aHRs) of acute readmission (30-day and 90-day) for psychiatric and substance use disorders were estimated using multivariable Cox proportional hazards regression. RESULTS The cohort comprised 3907 individuals who were predominantly male (61.89%) with a severe mental illness (70.92%), substance use disorder (20.45%) and mean age of 40.66 (SD, 14.33). A total of 686 (17.56%) individuals were homeless at their index hospitalization averaging 19.13 (21.53) days in hospital. After adjusting for covariates, patients experiencing homelessness had a 2.04 (1.65, 2.51) increased rate of 30-day readmission and 1.65 (1.24, 2.19) increased rate of 90-day readmission during the observation period. CONCLUSIONS Homelessness was significantly associated with increased 30-day and 90-day readmission rates in a large comprehensive sample of adults with mental illness and substance use disorders. Interventions to reduce homelessness are urgently needed. QUESTION Is homelessness associated with risk for 30-day and 90-day psychiatric hospital readmission? FINDINGS In this retrospective cohort study of 3907 individuals, homelessness at discharge was associated with increased 30-day and 90-day psychiatric readmission. MEANING Housing status is an important risk factor for hospital readmission. High-quality interventions focused on housing supports have the potential to reduce psychiatric readmission.

Abstract
Anxiety disorders are frequent, with a 12-month prevalence of 14%, tend to be chronic, and display a high comorbidity with substance abuse disorders. Anxiety and substance abuse disorders are associated with a pronounced individual as well as socioeconomic burden. This article reviews the epidemiological, etiological, and clinical aspects of the dual diagnosis of anxiety and substance abuse disorders, with a particular focus on alcohol and cannabis. The treatment comprises nonpharmacological strategies, mainly cognitive behavioral therapy combined with elements of motivational interviewing (MI) and pharmacological management with antidepressants; however, the use of selective serotonin reuptake inhibitors (SSRI)/serotonin and noradrenaline reuptake inhibitors (SNRI) is not unreservedly recommended. The use of gabapentinoids requires careful risk-benefit consideration because of their potential for abuse and dependence in substance abuse disorders. Benzodiazepines are reserved exclusively for crisis management. Rapid diagnosis and treatment initiation targeting both disorders are essential for successful treatment of comorbid anxiety and substance abuse disorders.

Abstract
BACKGROUND Globally, the rise in the number of people living with a substance use disorder (SUD) carries a multitude of individual and social health implications for carers and their families, often impacting negatively on their quality of life. Considered from a harm reduction approach, SUD is understood as a chronic protracted, complex health and social condition. From the extant literature, there is no evidence of the harm reduction approach being applied to address the needs of carers/family members who carry the burden of SUD care. This study preliminarily evaluated the Care4Carers Programme. It is a purposively designed set of brief interventions to improve the coping self-efficacy of carers of people with SUD (PwSUD carers) by equipping them to think about ways to exert control over their motivation, behaviours and social environment. METHODS A pre-experimental, one group pretest-posttest design was implemented with 15 purposively selected participants in the Gauteng Province of South Africa. The intervention was conducted by the lead researcher, a registered social worker. Eight brief intervention sessions were held, over 5-6 weeks at research sites where the participants were identified. The coping self-efficacy scale was completed before and directly after exposure to the programme. Results were analysed using paired t-tests. RESULTS There were statistically significant (p < .05) improvements in carers' coping self-efficacy, both overall and in respect of each of its constituent components: problem-focused coping, emotion-focused coping and social support strategies. CONCLUSIONS The Care4Carers Programme improved the coping self-efficacy of carers of people living with SUDs. The application of this programmatic harm reduction intervention to support PwSUD carers should be tested on a larger scale across South Africa.

Abstract
INTRODUCTION Opioid agonist treatment (OAT) is the first-line treatment for opioid use disorder (OUD). Simultaneously, opioids are essential medicines in acute pain management. The literature is scarce on acute pain management in individuals with OUD, and guidelines are controversial for patients on OAT. We aimed at analyzing rescue analgesia in opioid-dependent individuals on OAT during hospitalization in the University Hospital Basel, Switzerland. METHODS Patient hospital records were extracted from the database over 6 months (Jan-Jun) in 2015 and 2018. Of the 3,216 extracted patient records, we identified 255 cases on OAT with full datasets. Rescue analgesia was defined according to established principles of acute pain management, e.g., i) the analgesic agent is identical to the OAT medication, and ii) the opioid agent is dosed above 1/6th morphine equivalent dose of the OAT medication. RESULTS The patients were on average 51.3 ± 10.5 years old (range: 22-79 years), of which 64% were men. The most frequent OAT agents were methadone and morphine (34.9% and 34.5%). Rescue analgesia was not documented in 14 cases. Guideline-concordant rescue analgesia was observed in 186 cases (72.9%) and consisted mostly of NSAIDs, including paracetamol (80 cases), and identical agents such as the OAT opioid (70 cases). Guideline-divergent rescue analgesia was observed in 69 (27.1%) cases, predominantly due to an underdosed opioid agent (32 cases), another agent other than the OAT (18 cases), or contraindicated agents (10 cases). DISCUSSION Our analysis suggests that rescue analgesia in hospitalized OAT patients was predominantly concordant with guidelines, while divergent prescriptions seemed to follow common principles of pain medicine. Clear guidelines are needed to appropriately treat acute pain in hospitalized OAT patients.

Abstract
BACKGROUND Cognitive control and the attribution of incentive salience are two key neuropsychological processes proposed to explain substance use disorder (SUD). However, little is known about how they interact to influence the severity of drug use in people with SUD. OBJECTIVE To determine if cognitive control exerts a moderating effect on the relation between the attribution of salience to drug/reward-related cues and the severity of drug use in SUD cases. METHOD Sixty-nine SUD cases with methamphetamine as the main drug of consumption were selected and evaluated. Participants performed the Stroop, Go/No-Go, and Flanker tasks to identify a latent cognitive control factor, and the Effort-Expenditure for Reward task, as well as answering the Methamphetamine Incentive Salience Questionnaire to measure the attribution of incentive salience. Severity of drug use was determined by the KMSK scale and an exploratory clinical interview. RESULTS As expected, higher incentive salience attribution predicted greater severity of methamphetamine use. Unexpectedly, however, we found a moderating effect of impaired cognitive control on the relations between higher incentive salience scores and higher monthly drug use, and between younger age at onset of systematic drug use and higher incentive salience scores. CONCLUSION Results show the moderating role of cognitive control on the relation between incentive salience attribution and severity of drug use in SUD cases, and help explain the chronic, relapsing nature of addiction, knowledge necessary to develop more precise prevention and treatment strategies.

Abstract
BACKGROUND Breaking Free Online (BFO), a computer-assisted therapy (CAT) program for substance use disorders (SUD), has been available across UK treatment services for the past decade and has demonstrated efficacy. The Covid-19 pandemic has contributed to digital and 'telehealth' approaches to healthcare delivery becoming more common and accepted, and has in parallel, increased numbers of referrals to SUD services because of the impact pandemic-related stress has had on substance using habits in the general population. Digital and telehealth approaches, such as BFO, have the potential to support the treatment system to meet this increased demand for SUD services. METHODS Parallel-group randomized controlled trial of eight-week BFO as an adjunct to standard treatment for SUD, in comparison to standard treatment only, at a National Health Service (NHS) Mental Health Trust in North-West England. Participants will be service users aged 18 years and over with demonstrable SUD for at least 12-months. Interventional and control groups will be compared on multiple measures from baseline to post-treatment assessment at eight-weeks, and then three and six-months follow-up. Primary outcome will be self-reported substance use, with secondary outcomes being standardized assessments of substance dependence, mental health, biopsychosocial functioning and quality of life. DISCUSSION This study will examine whether BFO and telehealth support, when delivered as an adjunct to standard SUD interventions, improves outcomes for services users receiving NHS SUD treatment. Findings from the study will be used to inform both developments to the BFO program and guidance around augmenting the delivery of CAT programs via telehealth. Trial registration registered with ISRCTN on 25th May 2021-registration number: 13694016. PROTOCOL VERSION 3.0 05th April 2022. TRIAL STATUS This trial is currently open to recruitment-estimated to be completed in May 2023.

Abstract
Health care environments have historically faced stressful situations that place those working in those environments at risk for substance use disorders. Over the past several years, the rates of burnout, workplace violence, diverse population stigmatization, and mental health concerns (including suicide) during the Covid-19 pandemic have increased, further challenging and contributing to development of negative coping skills, including use of substances to reduce the side effects and emotions from work. This article introduces the problem of substance use disorders, pathophysiology, and how the challenges contribute to the development of turning to substances to cope.

Abstract
Introduction Previous research has established co-occurrence between substance use disorders (SUDs) and gambling disorder (GD). Less well understood is the temporal sequencing of onset between these disorders, and in particular whether SUD is a risk factor for GD. The present study examined the temporal order between registered diagnoses of SUD and GD, stratified by sex. Methods A study with a longitudinal design using objective registry data drawn from the Norwegian Patient Registry was carried out. Among the patients with a registered diagnosis of GD between 2008 and 2018 (N = 5,131; males = 81.8%), those (who in addition) had a registered diagnosis of any SUD (n = 1,196; males = 82.1%) were included. The measures included a registered diagnosis using the ICD-10 of both GD (code F63.0) and SUDs (codes F10-F19) by a health care professional. Binomial tests were used to identify the temporal order between SUD(s) and GD. Co-occurring cases (i.e., cases diagnosed within the same month) were removed in the main analyses. Results Results showed a significant directional path from SUD to GD but no support for the reversed path (i.e., from GD to SUD). This finding was similar overall for (i) both males and females, (ii) when different SUDs (alcohol, cannabis, sedatives, and polysubstance) were examined individually, and (iii) when specifying a 12-month time-lag between diagnoses. Conclusions The findings suggest that experiencing SUD(s) is a risk marker for GD given the temporal precedence observed for patients in specialised healthcare services seeking treatment. These results should be considered alongside screening and prevention efforts for GD.

Abstract
Substance use disorders (SUDs) are highly prevalent and exact a large toll on individuals' health, well-being, and social functioning. Long-lasting changes in brain networks involved in reward, executive function, stress reactivity, mood, and self-awareness underlie the intense drive to consume substances and the inability to control this urge in a person who suffers from addiction (moderate or severe SUD). Biological (including genetics and developmental life stages) and social (including adverse childhood experiences) determinants of health are recognized factors that contribute to vulnerability for or resilience against developing a SUD. Consequently, prevention strategies that target social risk factors can improve outcomes and, when deployed in childhood and adolescence, can decrease the risk for these disorders. SUDs are treatable, and evidence of clinically significant benefit exists for medications (in opioid, nicotine and alcohol use disorders), behavioral therapies (in all SUDs), and neuromodulation (in nicotine use disorder). Treatment of SUDs should be considered within the context of a Chronic Care Model, with the intensity of intervention adjusted to the severity of the disorder and with the concomitant treatment of comorbid psychiatric and physical conditions. Involvement of health care providers in detection and management of SUDs, including referral of severe cases to specialized care, offers sustainable models of care that can be further expanded with the use of telehealth. Despite advances in our understanding and management of SUDs, individuals with these conditions continue to be stigmatized and, in some countries, incarcerated, highlighting the need to dismantle policies that perpetuate their criminalization and instead develop policies to ensure support and access to prevention and treatment.

Abstract
Microglia are widely known for their role in immune surveillance and for their ability to refine neurocircuitry during development, but a growing body of evidence suggests that microglia may also play a complementary role to neurons in regulating the behavioral aspects of substance use disorders. While many of these efforts have focused on changes in microglial gene expression associated with drug-taking, epigenetic regulation of these changes has yet to be fully understood. This review provides recent evidence supporting the role of microglia in various aspects of substance use disorder, with particular focus on changes to the microglial transcriptome and the potential epigenetic mechanisms driving these changes. Further, this review discusses the latest technical advances in low-input chromatin profiling and highlights the current challenges for studying these novel molecular mechanisms in microglia.

Abstract
BACKGROUND Psychiatric illness is a well-established risk factor for criminal justice system involvement, but less is known about the relationships between specific psychiatric illnesses and reoffending. Research typically examines reoffending as a single discrete event. We examined the relationship between different psychiatric disorders and types of reoffending while accounting for multiple reoffending events over time. METHODS Data were drawn from a population cohort of 83,039 individuals born in Queensland, Australia, in 1983 and 1984 and followed to age 29-31 years. Psychiatric diagnoses were drawn from inpatient health records and offending information was drawn from court records. Descriptive and recurrent event survival analyses were conducted to examine the association between psychiatric disorders and reoffending. RESULTS The cohort included 26,651 individuals with at least one proven offence, with 3,580 (13.4%) of these individuals also having a psychiatric disorder. Individuals with any psychiatric disorder were more likely to reoffend compared to those without a disorder (73.1% vs. 56.0%). Associations between psychiatric disorders and reoffending varied across age. Individuals with a psychiatric disorder only started to accumulate more reoffending events from ~ 27 years, which accelerated up to age 31 years. There were both specificity and common effects in the associations between different psychiatric disorders and types of reoffending. CONCLUSIONS Findings demonstrate the complexity and temporal dependency of the relationship between psychiatric illness and reoffending. These results reveal the heterogeneity present among individuals who experience psychiatric illness and contact with the justice system, with implications for intervention delivery, particularly for those with substance use disorders.

Abstract
OBJECTIVE We investigated adult-onset epilepsy as a risk factor for the development of substance use disorder (SUD) by comparing the rate of SUD diagnosis among adults diagnosed with epilepsy with presumably healthy controls with lower extremity fractures (LEF). For additional comparison, we investigated the risk for adults with migraine only. Epilepsy and migraine are both episodic neurological disorders and migraine is frequently comorbid with epilepsy. METHODS We conducted a time-to-event analysis using a subset of surveillance data of hospital admissions, emergency department visits, and outpatient visits in South Carolina, USA from January 1, 2000, through December 31, 2011. Individuals aged 18 years or older were identified using the International Classification of Disease, 9thRevision Clinical Modification (ICD-9) with a diagnosis of epilepsy (n = 78,547; 52.7% female, mean age 51.3 years), migraine (n = 121,155; 81.5% female, mean age 40.0 years), or LEF (n = 73,911; 55.4% female, mean age 48.7 years). Individuals with SUD diagnosis following epilepsy, migraine, or LEF were identified with ICD-9 codes. We used Cox proportional hazards regression to model the time to SUD diagnosis comparing adults diagnosed with epilepsy, migraine, and LEF, adjusting for insurance payer, age, sex, race/ethnicity, and prior mental health comorbidities. RESULTS Compared to LEF controls, adults with epilepsy were diagnosed with SUD at 2.5 times the rate [HR 2.48 (2.37, 2.60)] and adults with migraine only were diagnosed with SUD at 1.12 times the rate [HR 1.12 (1.06, 1.18)]. We found an interaction between disease diagnosis and insurance payer, with hazard ratios comparing epilepsy to LEF of 4.59, 3.48, 1.97, and 1.44 within the commercial payer, uninsured, Medicaid, and Medicare strata, respectively. SIGNIFICANCE Compared to presumably healthy controls, adults with epilepsy had a substantially higher hazard of SUD, while adults with migraine only showed a small, but significant, increased hazard of SUD.

Abstract
BACKGROUND Although depressive symptoms represent a promising therapeutic target to promote recovery from substance use disorders (SUD), heterogeneity in their diagnostic presentation often hinders the ability to effectively tailor treatment. We sought to identify subgroups of individuals varying in depressive symptom phenotypes (i.e., demoralization, anhedonia), and examined whether these subgroups were associated with patient demographics, psychosocial health, and treatment attrition. METHODS Patients (N = 10,103, 69.2 % male) were drawn from a dataset of individuals who presented for admission to SUD treatment in the US. Participants reported on their demoralization and anhedonia approximately weekly for the first month of treatment, and on their demographics, psychosocial health, and primary substance at intake. Longitudinal latent profile analysis examined patterns of demoralization and anhedonia with treatment attrition as a distal outcome. RESULTS Four subgroups of individuals emerged: (1) High demoralization and anhedonia, (2) Remitting demoralization and anhedonia, (3) High demoralization, low anhedonia, and (4) Low demoralization and anhedonia. Relative to the Low demoralization and anhedonia subgroup, all the other profiles were more likely to discontinue treatment. Numerous between-profile differences were observed in demographics, psychosocial health, and primary substance. LIMITATIONS The racial and ethnic background of the sample was skewed towards White individuals; future research is needed to determine the generalizability of our findings to minoritized racial and ethnic groups. CONCLUSIONS We identified four clinical profiles that varied in the joint course of demoralization and anhedonia. Findings suggest specific subgroups might benefit from additional interventions and treatments that address their unique mental health needs during SUD recovery.
