Outcomes of an adapted prolonged exposure psychotherapy for people with early phase psychosis, substance misuse, and a history of adversity: the PE + trial.

BACKGROUND: Several adversity-focused treatment trials have reported improvements to adversity sequelae (e.g., PTSD symptoms) and decreases in psychotic symptoms among individuals with psychotic disorders. Yet, no trials have examined the impact of adversity-focused treatment on substance use or examined the outcomes among an early phase psychosis population. These gaps in both the research literature and clinical practice have resulted in less knowledge about the outcomes of adversity-focused treatment at this stage of illness, including the impact on substance use. METHODS: The outcomes of an adapted prolonged exposure protocol (PE+) among an early phase psychosis population were examined using a multiple-baseline design. Nineteen adults with a psychotic disorder, current substance misuse, and a history of adversity were recruited from an early psychosis program. Participants were randomized to treatment start time and participated in a 15-session course of PE + therapy. Ten assessments were completed focusing on primary outcomes (i.e., adversity sequelae, negative psychotic symptoms, substance misuse) and secondary outcomes (i.e., functioning, hopelessness, experiential avoidance). The Reliable Change Index (RCI) was used to establish whether there were clinically significant changes to primary or secondary outcomes. RESULTS: Half or more of treatment completers experienced clinically significant changes to most domains of adversity sequelae, no participants experienced improvements in negative psychotic symptoms, and substance misuse increased for several participants. In terms of secondary outcomes, functioning and experiential avoidance were improved for a number of participants, while hopelessness decreased for only one participant. Participants reported high satisfaction with the PE + treatment, and exposure and coping skills were rated as the most helpful elements of treatment. CONCLUSIONS: Reductions in adversity sequelae were observed following PE + treatment, suggesting that adversity-focused treatment may be beneficial for an early psychosis population. Yet, few positive changes to psychotic symptoms or substance use were observed. Further integrating treatment strategies for psychosis and substance use into PE + may be required to effectively treat the links between psychosis, adversity sequelae, and substance use. Future studies should make efforts to integrate substance use strategies into adversity treatment trials for people with psychotic disorders.

Parental domestic violence and abuse, mental ill-health, and substance misuse and the impact on child mental health: a secondary data analysis using the UK Millennium Cohort Study.

BACKGROUND: Parental domestic violence and abuse (DVA), mental ill-health (MH), and substance misuse (SU) can have a negative impact on both parents and children. However, it remains unclear if and how parental DVA, MH, and SU cluster and the impacts this clustering might have. We examined how parental DVA, MH, and SU cluster during early childhood, the demographic/contextual profiles of these clusters, and how these clusters relate to child MH trajectories. METHODS: We examined data from 15,377 families in the UK Millennium Cohort Study. We used: (1) latent class analysis to create groups differentially exposed to parental DVA, MH, and SU at age three; (2) latent growth curve modelling to create latent trajectories of child MH from ages 3-17; and (3) a case-weight approach to relate latent classes to child MH trajectories. RESULTS: We identified three latent classes: high-frequency alcohol use (11.9%), elevated adversity (3.5%), and low-level adversity (84.6%). Children in the elevated adversity class had higher probabilities of being from low-socioeconomic backgrounds and having White, younger parents. Children exposed to elevated adversity displayed worse MH at age three (intercept = 2.274; p < 0.001) compared the low-level adversity (intercept = 2.228; p < 0.001) and high-frequency alcohol use class (intercept = 2.068; p < 0.001). However, latent growth factors (linear and quadratic terms) of child MH did not differ by latent class. CONCLUSIONS: Parental DVA, MH, and SU cluster during early childhood and this has a negative impact on children's MH at age three, leading to similar levels of poor MH across time. Intervening early to prevent the initial deterioration, using a syndemic-approach is essential.

The contribution of pain catastrophizing, depression and anxiety symptoms among patients with persistent pain and opioid misuse behaviours.

BACKGROUND: Anxiety, depression and pain catastrophizing are independently associated with risk of opioid misuse in patients with persistent pain but their relationship to current opioid misuse, when considered together, is poorly understood. This study will assess the relative contribution of these modifiable, and distinct psychological constructs to current opioid misuse in patients with persistent pain. METHODS: One hundred and twenty-seven patients referred to a specialized opioid management clinic for prescription opioid misuse within a tertiary pain service were recruited for this study. The Pain Catastrophizing Scale, Depression, Anxiety and Stress Scales and the Current Opioid Misuse Measure were administered pre-treatment. Pain severity and morphine equivalent dose based on independent registry data were also recorded. RESULTS: Higher levels of pain catastrophizing, depression, and anxiety were significantly associated with higher current opioid misuse (r = .475, 0.599, and 0.516 respectively, p < .01). Pain severity was significantly associated with pain catastrophizing (r = .301, p < .01). Catastrophizing, depression, and anxiety explained an additional 11.56% of the variance (R2 change = 0.34, p < .01) over and above age, gender, pain severity and morphine equivalent dose. Depression was the only significant variable at Step 2 (ß = 0.62, p < .01). CONCLUSION: Findings show that in a sample of people with persistent pain referred for treatment for opioid misuse, depression contributes over and above that of anxiety and pain catastrophizing. Theoretical and clinical practice implications are presented.

Paternal morphine exposure in rats reduces social play in adolescent male progeny without affecting drug-taking behavior in juvenile males or female offspring.

The ongoing opioid addiction crisis necessitates the identification of novel risk factors to improve prevention and treatment of opioid use disorder. Parental opioid exposure has recently emerged as a potential regulator of offspring vulnerability to opioid misuse, in addition to heritable genetic liability. An understudied aspect of this "missing heritability" is the developmental presentation of these cross-generational phenotypes. This is an especially relevant question in the context of inherited addiction-related phenotypes, given the prominent role of developmental processes in the etiology of psychiatric disorders. Paternal morphine self-administration was previously shown to alter the sensitivity to the reinforcing and antinociceptive properties of opioids in the next generation. Here, phenotyping was expanded to include the adolescent period, with a focus on endophenotypes related to opioid use disorders and pain. Paternal morphine exposure did not alter heroin or cocaine self-administration in male and female juvenile progeny. Further, baseline sensory reflexes related to pain were unaltered in morphine-sired adolescent rats of either sex. However, morphine-sired adolescent males exhibited a reduction in social play behavior. Our findings suggest that, in morphine-sired male offspring, paternal opioid exposure does not affect opioid intake during adolescence, suggesting that this phenotype does not emerge until later in life. Altered social behaviors in male morphine-sired adolescents indicate that the changes in drug-taking behavior in adults sired by morphine-exposed sires may be due to more complex factors not yet fully assessed.

Expanding access to substance misuse services through emergency medical services: envisioning a novel partnership for addiction medicine clinicians.

Emergency medical services (EMS) can be an invaluable ally of addiction medicine clinicians, but the potential role of EMS in combating the opioid epidemic has been under-realized. EMS has historically focused on emergency response and resuscitation in cases of overdose; however, EMS is also well-positioned to build rapport with persons who use drugs (PWUD), provide harm reduction services, and connect PWUD with additional treatment services and resources. A select number of EMS organizations have begun to offer substance-related programming that extends beyond resuscitation, but these offerings remain limited in scope and impact. This perspective argues that addiction medicine clinicians can bolster the ability of EMS to provide high quality substance-related services by engaging in prehospital care education, program development and research, and clinical care. This perspective shares practical strategies for addiction medicine clinicians to partner with EMS and considers several potential barriers that must be overcome, including bureaucratic challenges, variability in the scope of practice of EMS providers across different locations, and limited funding.

Assessing experts' perspectives on challenges in substance misuse prevention, harm reduction, and treatment to shape funding priorities in New York State.

BACKGROUND: Drug overdose is a leading cause of death and opioid-related deaths increased by more than 300% from 2010 to 2020 in New York State. Experts holding a range of senior leadership positions from across New York State were asked to identify the greatest challenges in substance misuse prevention, harm reduction, and treatment continuum of care. Expert input was used to shape funding priorities. METHOD: Individual semi-structured interviews of sixteen experts were conducted in April and May 2023. Experts included academics, medical directors, leaders of substance misuse service agencies, administrators of a state agency, a county mental health commissioner, the president of a pharmacy chain, and a senior vice president of an addiction-related national non-profit. Zoom interviews were conducted individually by an experienced qualitative interviewer and were recorded, transcribed, and coded for content. An initial report, with the results of the interviews organized by thematic content, was reviewed by the research team and emailed to the expert interviewees for feedback. RESULTS: The research team identified five major themes: 1. Siloed and fragmented care delivery systems; 2. Need for a skilled workforce; 3. Attitudes towards addiction (stigma); 4. Limitations in treatment access; and 5. Social and drug related environmental factors. Most experts identified challenges in each major theme; over three-quarters identified issues related to siloed and fragmented systems and the need for a skilled workforce. Each expert mentioned more than one theme, three experts mentioned all five themes and six experts mentioned four themes. CONCLUSIONS: Research, educational, and programmatic agendas should focus on identified topics as a means of improving the lives of patients at risk for or suffering from substance use-related disorders. The results of this project informed funding of pilot interventions designed to address the identified care challenges.

The Impact of Social Support and Social Network Characteristics on Trauma Symptoms Among Violence-Exposed Women with Substance Use Disorders.

Background: Women with substance use disorder (SUD) experience higher rates of violence exposure, post-traumatic stress disorder (PTSD), and post-traumatic stress symptoms (PTSS) than their non-substance-using peers. Exposure to violence in women with SUD is associated with PTSS symptom severity and leads to lower rates of treatment adherence, poorer treatment outcomes, and a higher risk for relapse. Little is known about the buffers to PTSS among violence-exposed women with SUD. Methods: A sample of 375 women with SUD were recruited from three inner-city intensive treatment centers, in a midwestern city. Using ordinary least squares regression models, we sought to identify the direct effects of violence, general social support, recovery-specific social support, and social network composition on PTSS. Moderation was also examined using the Bootstrapping function in PROCESS macro for SPSS. Results: General social support, recovery social support, and greater duration of network relationships were associated with lower trauma symptom scores. General social network composition variables were directly associated with lower trauma symptom severity. Recovery-specific social network variables moderated the association between violence exposure and PTSS for Black participants only. Conclusions: These data suggest that providers should target the quality of the client's interpersonal relationships to reduce PTSS among violence-exposed women with SUD. Maintaining social network relationships should be the focus of treatment interventions for women with SUD who have experienced violence.

Illicit drug use in Limerick City: A stakeholder and policy analysis using multiple streams model.

BACKGROUND: The changing drug situation in Ireland has led to the development of various drug policies. This paper aims to use Limerick City as a case study to examine approaches to policy development. METHODOLOGY: The study is qualitative and uses a hybrid technique that combines document, content, and stakeholder analysis. Kingdon's multiple streams model underpins this study. In addition, guidelines for the systematic search for grey literature were adopted as the search strategy. RESULTS: Problem Stream: Illicit drug use and its related problems have changed. The increasing availability of drugs, increasing usage and changes in the types of drugs being used have led to increased drug-related crimes, adverse health outcomes and elevated demand for treatment services. Local drug policies and initiatives emerge by recognising drug-related problems in the region. Policy Stream: The current national drug strategy 2017-2025 which informs action plans in Limerick is the first to focus on a unified health approach. Some national policies have evolved to ensure that guidelines meet current service needs. However, these changes have occurred in some cases with no clear actions. Political Stream: Statutory, voluntary and community stakeholders provide drug addiction and drug addiction-related services, which have evolved rapidly since their first introduction. The Mid-West Regional Drug Task Force was identified as essential in coordinating stakeholders locally. One area for improvement is limited evidence of the voices of persons who take drugs included in service/policy development. This regional analysis also suggests that local implementation of policies concerning dual diagnosis and supervised injection facilities can be further expanded. Despite the challenges experienced by stakeholders in Limerick, a hands-on approach has been adopted in the creation of strategies to tackle the drug problem. CONCLUSION: The approaches to drug policy development have delivered continuous development of services. However, services remain underdeveloped in areas removed from the capital city of Dublin. Navigating the complex drug landscape reveals that inclusivity, adaptation, and ongoing research are critical components of successful and long-lasting drug policies.

Addressing substance use disorder in a hospital prenatal setting.

Pregnancy can be a time of joy and hope but, for birthing parents struggling with a substance use disorder (SUD), it can be challenging. Social stigma, shame, and the potential legal ramifications present barriers to individuals seeking the care they need. Marginalized groups, in particular, face challenges that put them at even greater risk for substance misuse. Substance use during pregnancy can further impair the individual's level of functioning, and it has also been associated with problems in the social, emotional, and cognitive development of their children. Pregnancy and addiction each require guidance and good medical care. By integrating substance misuse treatment services under the umbrella of their medical care, clinics facilitate timely access to care, as well as help break the stigma associated with substance misuse. Our program offers a comprehensive and multidisciplinary approach to support pregnant individuals with SUDs. Interventions include support, education, case management, and mental health counseling. By providing optimal prenatal care early on, individuals can receive the treatment that they need so that they can achieve physical and emotional stability once the baby arrives, which ultimately has better outcomes for the parent and child's health and wellbeing.

Psychological flexibility, self-compassion, subjective well-being, and substance misuse in college students: a serial mediation model.

Substance misuse is a pressing public health concern, especially among emerging adults, with implications for psychological health and overall well-being. This cross-sectional study investigates the mediating roles of self-compassion and subjective well-being in the relationship between psychological flexibility and substance misuse among Turkish college students. The study included 445 emerging adults enrolled at a state university in Türkiye. University participants were recruited via convenience sampling using snowball methods. Data were collected using self-report scales. The sample was 69% female (n = 307) and 31% male (n = 138) and ranged in age from 18 to 26 years (M = 20.85, SD = 1.35). In the study, Pearson product-moment correlation analysis was conducted to examine the relationships between the variables and then the serial mediation model was tested. The findings have revealed that psychological flexibility significantly predicts substance misuse, subjective well-being, and self-compassion. Additionally, the study identifies self-compassion as a mediator in the relationship between psychological flexibility and subjective well-being. While self-compassion contributes significantly to well-being, it does not explain the impact of psychological flexibility on substance misuse. Furthermore, subjective well-being also appears to be a mediator in the relationship between psychological flexibility and substance misuse, emphasizing its potential significance in reducing the likelihood of resorting substance misuse. Overall, the study contributes to understanding the pivotal role of self-compassion and psychological flexibility in fostering well-being and preventing substance misuse in the college setting.

Examining the Associations Between Substance Misuse and Suicide Bereavement.

Focusing on the understudied question of substance misuse among suicide bereaved adults we investigated patterns of binge drinking and non-prescribed drug use among a recently bereaved sample (n = 1,132). Comparing our respondents to the non-bereaved, those in the 2022 National Survey of Drug Use and Health (n = 71,369), we did not find heightened problematical substance misuses among our respondents. With t-tests and multiple regression analyses we examined whether binge drinkers and non-prescribed drug users had heightened levels of grief difficulties, PTSD, self-blaming and depression compared to others not bingeing or using non-prescribed drugs. Results showed binge drinkers had more of all these grieving problems when important confounding variables were also considered. Analysis of the demographic correlates of bingeing showed them dimly aware of their own additional grieving and substance misusing problems. Since 75% indicated being under the care of counseling professionals, this represents an important opportunity for psycho-educational helping.

Tracing the origins of midlife despair: association of psychopathology during adolescence with a syndrome of despair-related maladies at midlife.

BACKGROUND: Midlife adults are experiencing a crisis of deaths of despair (i.e. deaths from suicide, drug overdose, and alcohol-related liver disease). We tested the hypothesis that a syndrome of despair-related maladies at midlife is preceded by psychopathology during adolescence. METHODS: Participants are members of a representative cohort of 1037 individuals born in Dunedin, New Zealand in 1972-73 and followed to age 45 years, with 94% retention. Adolescent mental disorders were assessed in three diagnostic assessments at ages 11, 13, and 15 years. Indicators of despair-related maladies across four domains - suicidality, substance misuse, sleep problems, and pain - were assessed at age 45 using multi-modal measures including self-report, informant-report, and national register data. RESULTS: We identified and validated a syndrome of despair-related maladies at midlife involving suicidality, substance misuse, sleep problems, and pain. Adults who exhibited a more severe syndrome of despair-related maladies at midlife tended to have had early-onset emotional and behavioral disorders [ß = 0.23, 95% CI (0.16-0.30), p < 0.001], even after adjusting for sex, childhood SES, and childhood IQ. A more pronounced midlife despair syndrome was observed among adults who, as adolescents, were diagnosed with a greater number of mental disorders [ß = 0.26, 95% CI (0.19-0.33), p < 0.001]. Tests of diagnostic specificity revealed that associations generalized across different adolescent mental disorders. CONCLUSIONS: Midlife adults who exhibited a more severe syndrome of despair-related maladies tended to have had psychopathology as adolescents. Prevention and treatment of adolescent psychopathology may mitigate despair-related maladies at midlife and ultimately reduce deaths of despair.

Nicotinic regulation of microglia: potential contributions to addiction.

Clinical and preclinical studies have identified immunosuppressive effects of nicotine, with potential implications for treating nicotine addiction. Here we review how nicotine can regulate microglia, the resident macrophages in the brain, and corresponding effects of nicotine on neuroimmune signaling. There is significant evidence that activation of α7 nicotinic acetylcholine receptors (nAChRs) on microglia can trigger an anti-inflammatory cascade that alters microglial polarization and activity, cytokine release, and intracellular calcium concentrations, leading to neuroprotection. These anti-inflammatory effects of nicotine-dependent α7 nAChR signaling are lost during withdrawal, suggesting that neuroimmune signaling is potentiated during abstinence, and thus, heightened microglial activity may drive circuit disruption that contributes to withdrawal symptoms and hyperkatifeia. In sum, the clinical literature has highlighted immunomodulatory effects of nicotine and the potential for anti-inflammatory compounds to treat addiction. The preclinical literature investigating the underlying mechanisms points to a role of microglial engagement in the circuit dysregulation and behavioral changes that occur during nicotine addiction and withdrawal, driven, at least in part, by activation of α7 nAChRs on microglia. Specifically targeting microglial signaling may help alleviate withdrawal symptoms in people with nicotine dependence and help to promote abstinence.

Behavior change, health, and health disparities 2023: Contingency management for treating substance use disorders and promoting health in vulnerable populations.

This Special Issue (SI) of Preventive Medicine is the 10th in a series on behavior change, health, and health disparities. This issue focuses on Contingency Management (CM), a highly efficacious behavior-change intervention for substance use disorders (SUDs) and other behavioral health conditions wherein patients receive material incentives (e.g., vouchers exchangeable for retail items) contingent on objectively verified behavior change. Despite substantial support for its efficacy, CM remains largely unavailable in U.S. community SUD treatment facilities and other healthcare settings. This is especially concerning regarding stimulant use disorder for which CM is the only reliably efficacious intervention in controlled studies and yet is unavailable to the vast majority of those in need. This SI details recent promising developments in efforts to surmount longstanding implementation obstacles while also detailing other promising advances from meta-analyses and controlled trials examining CM's efficacy in treating other difficult-to-treat problems including smoking among pregnant women and mothers of young children as well among those as those experiencing homelessness and alcohol use disorder, the promise of digital CM, and a potential new application in promoting adherence with SUD medications.

Epidemiological associations of asthma status and tobacco use, substance use, and substance misuse among adults in the United States, 2015-2019.

Objective: Adults with asthma have a higher prevalence of substance use. However, knowledge is scarce regarding the associations between adults with asthma and tobacco use, substance use, and substance misuse. This study aimed to use national samples of United States adults to assess the comprehensive use and misuse of substances in adults with asthma.Method: This cross-sectional study comprised data drawn from the 2015 to 2019 National Survey on Drug Use and Health. Weighted logistic regressions were used to measure the associations of asthma status (lifetime and current) with last month's tobacco use; substance use (alcohol, marijuana, cocaine, crack, heroin, hallucinogens, inhalants); and substance misuse (pain relievers, tranquilizers, stimulants, sedatives). All regression models were controlled for sociodemographic characteristics, comorbidity, last-month serious psychological distress, and co-substance use and misuse. Results: Adults with lifetime asthma (Nweighted = 115,600,887) were less likely to use cigarettes, cigars, smokeless tobacco, inhalants, and polyuse of any substance. In contrast, adults with current asthma (Nweighted = 765,096,31) were more likely to use pipe tobacco, cocaine, non-prescribed tranquilizers, and less likely to use polytobacco products. Adults with lifetime asthma were associated with fewer last-month tobacco and inhalant use than those without lifetime asthma. However, adults with current asthma were associated with greater last month's pipe tobacco, cocaine, and non-prescribed tranquilizers. Conclusion: Thus, further longitudinal studies are recommended among adults with asthma to effectively design tailored treatment and prevention interventions.

Effectiveness of brief alcohol interventions for pregnant women: a systematic literature review and meta-analysis.

BACKGROUND: Prenatal alcohol exposure (PAE) can result in a range of adverse neonatal outcomes, including Fetal Alcohol Spectrum Disorder (FASD). This systematic review and meta-analysis sought to investigate the effectiveness of brief interventions (BIs) in eliminating or reducing 1) alcohol consumption during pregnancy; and 2) PAE-related adverse neonatal outcomes; and 3) cost-effectiveness of BIs. METHOD: We conducted a systematic literature search for original controlled studies (randomized control trials (RCTs); quasi-experimental) in any setting, published from 1987 to 2021. The comparison group was no/minimal intervention, where a measure of alcohol consumption was reported. Studies were critically appraised using the Centre for Evidence-based Medicine Oxford critical appraisal tool for RCTs (1). The certainty in the evidence for each outcome was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) (2). Meta-analysis of continuous and binary estimates of effect-size for similar outcome measures for BIs versus control groups were pooled and reported as mean difference (MD) Hedges' g and odds ratios (ORs), respectively. RESULTS: In total, 26 studies, all from high income countries, met inclusion criteria. Alcohol abstinence outcome available in 12 studies (n = 2620) found modest effects in favor of BIs conditions by increasing the odds of abstinence by 56% (OR = 1.56, 95% confidence interval (CI) = 1.15-2.13, I2 = 46.75%; p = 0.04). BIs effects for reduction in mean drinks/week (Cohen's d = - 0.21, 95%CI = - 0.78 to 0.36; p = 0.08) and AUDIT scores (g = 0.10, 95%CI = - 0.06 to 0.26; p = 0.17) were not statistically significant. Among seven studies (n = 740) reporting neonatal outcomes, BI receipt was associated with a modest and significant reduction in preterm birth (OR = 0.67, 95% CI = 0.46-0.98, I2 = 0.00%; p = 0.58). No statistically significant differences were observed for mean birthweight or lower likelihood of low birth weight (LBW). Certainty in the evidence was rated as 'low'. No eligible studies were found on cost-effectiveness of BIs. CONCLUSION: BIs are moderately effective in increasing abstinence during pregnancy and preventing preterm birth. More studies on the effectiveness of BIs are needed from low- and middle-income countries, as well as with younger mothers and with a broader range of ethnic groups.

Propofol misuse in medical professions: a scoping review.

PURPOSE: We aimed to describe the current literature concerning propofol misuse in medical professionals, specifically relating to the individual demographics of those misusing propofol and the outcomes of propofol misuse. METHODS: We conducted a retrospective scoping review of the literature using a modified PRISMA approach. We used MEDLINE, EMBASE, and PsycINFO databases to identify relevant studies based on search terms. Studies describing individual medical professionals misusing propofol were included. RESULTS: Twenty-four articles describing 88 individual cases of propofol misuse were included for data charting and analysis. Anesthesiologists and certified registered nurse anesthetists were most commonly identified. Death was a common method of identification of misuse, while rehabilitation and death were common final outcomes associated with propofol misuse. CONCLUSIONS: Despite knowledge of the pharmacokinetic and pharmacodynamic properties of propofol by those misusing this medication, death was a common outcome reported in the literature. Data related to long-term outcomes including re-entry to clinical practice or success of rehabilitation were limited.

RéSUMé: OBJECTIF: Nous avons cherché à décrire la littérature actuelle concernant l'abus de propofol chez les professionnels de la santé, en particulier en ce qui concerne les données démographiques individuelles de ceux qui abusent du propofol et les issues d'un tel abus. MéTHODE: Nous avons réalisé une étude de portée rétrospective de la littérature à l'aide d'une approche PRISMA modifiée. Nous avons utilisé les bases de données MEDLINE, EMBASE et PsycINFO pour identifier les études pertinentes en fonction des termes de recherche. Les études décrivant des professionnels de la santé abusant du propofol ont été incluses. RéSULTATS: Vingt-quatre articles décrivant 88 cas individuels d'abus de propofol ont été inclus pour la cartographie et l'analyse des données. Les anesthésiologistes et les infirmières anesthésistes autorisées certifiées ont été le plus souvent identifiés. La mort était une méthode courante d'identification de l'abus, tandis que la réhabilitation et la mort étaient des issues finales fréquemment associées à l'abus de propofol. CONCLUSION: Malgré la connaissance des propriétés pharmacocinétiques et pharmacodynamiques du propofol par ceux qui abusent de ce médicament, le décès était une issue fréquente rapportée dans la littérature. Les données relatives aux issues à long terme, y compris le retour à la pratique clinique ou le succès de la réhabilitation, étaient limitées.

A review on the reciprocal interactions between neuroinflammatory processes and substance use and misuse, with a focus on alcohol misuse.

Background: The last decade has witnessed a surge of findings implicating neuroinflammatory processes as pivotal players in substance use disorders. The directionality of effects began with the expectation that the neuroinflammation associated with prolonged substance misuse contributes to long-term neuropathological consequences. As the literature grew, however, it became evident that the interactions between neuroinflammatory processes and alcohol and drug intake were reciprocal and part of a pernicious cycle in which disease-relevant signaling pathways contributed to an escalation of drug intake, provoking further inflammation-signaling and thereby exacerbating the neuropathological effects of drug misuse.Objectives: The goal of this review and its associated special issue is to provide an overview of the emergent findings relevant to understanding these reciprocal interactions. The review highlights the importance of preclinical and clinical studies in testing and validation of immunotherapeutics as viable targets for curtailing substance use and misuse, with a focus on alcohol misuse.Methods: A narrative review of the literature on drug and neuroinflammation was conducted, as well as articles published in this Special Issue on Alcohol- and Drug-induced Neuroinflammation: Insights from Pre-clinical Models and Clinical Research.Results: We argue that (a) demographic variables and genetic background contribute unique sensitivity to drug-related neuroinflammation; (b) co-morbidities between substance use disorders and affect dysfunction may share common inflammation-related signatures that predict the efficacy of immunotherapeutic drugs; and (c) examination of polydrug interactions with neuroinflammation is a critical area where greater research emphasis is needed.Conclusions: This review provides an accessible and example-driven review of the relationship between drug misuse, neuroinflammatory processes, and their resultant neuropathological outcomes.

Differential risks of syringe service program participants in Central Ohio: a latent class analysis.

BACKGROUND: Significant heterogeneity exists among people who use drugs (PWUD). We identify distinct profiles of syringe service program (SSP) clients to (a) evaluate differential risk factors across subgroups and (b) inform harm reduction programming. METHODS: Latent class analysis (LCA) was applied to identify subgroups of participants (N = 3418) in a SSP in Columbus, Ohio, from 2019 to 2021. Demographics (age, sex, race/ethnicity, sexual orientation, housing status) and drug use characteristics (substance[s] used, syringe gauge, needle length, using alone, mixing drugs, sharing supplies, reducing use, self-reported perceptions on the impact of use, and treatment/support resources) were used as indicators to define latent classes. A five-class LCA model was developed, and logistic regression was then employed to compare risk factors at program initiation and at follow-up visits between latent classes. RESULTS: Five latent classes were identified: (1) heterosexual males using opioids/stimulants with housing instability and limited resources for treatment/support (16.1%), (2) heterosexual individuals using opioids with stable housing and resources for treatment/support (33.1%), (3) individuals using methamphetamine (12.4%), (4) young white individuals using opioids/methamphetamine (20.5%), and (5) females using opioids/cocaine (17.9%). Class 2 served as the reference group for logistic regression models, and at the time of entry, class 1 was more likely to report history of substance use treatment, overdose, HCV, sharing supplies, and mixing drugs, with persistently higher odds of sharing supplies and mixing drugs at follow-up. Class 3 was more likely to report history of overdose, sharing supplies, and mixing drugs, but outcomes at follow-up were comparable. Class 4 was the least likely to report history of overdose, HCV, and mixing drugs, but the most likely to report HIV. Class 5 was more likely to report history of substance use treatment, overdose, HCV, sharing supplies, and mixing drugs at entry, and higher reports of accessing substance use treatment and testing positive for HCV persisted at follow-up. CONCLUSIONS: Considerable heterogeneity exists among PWUD, leading to differential risk factors that may persist throughout engagement in harm reduction services. LCA can identify distinct profiles of PWUD accessing services to tailor interventions that address risks, improve outcomes, and mitigate disparities.

The Association between Potentially Traumatic Events and Cocaine, Cannabis, and Alcohol Use Differs by Race.

Background: Although exposure to potentially traumatic events (PTEs) for Black and Latinx may be comparable or lower than their White counterparts, type of trauma experiences differ such as more interpersonal trauma and violence reported by Black people, who also experience higher rates of PTSD. In this retrospective study, we examined the association between use of particular substances and various PTEs and the race/ethnicity-group differences for this association. Methods: One-hundred seventy-nine participants recruited from an outpatient substance use disorder program from February 2018 to October 2020 completed measures on lifetime trauma history and current/past cocaine, cannabis, and alcohol misuse. Bayesian generalized linear modeling with horseshoe prior was used to predict substance misuse using 17 PTEs, then PTEs were ranked and examined by racial/ethnic group. Results: No PTEs were associated with substance misuse across all four r/e groups. Transportation accident, natural disaster, war exposure, and other stressful events were associated with substance misuse across two or three r/e groups. Notably, the three PTEs involving interpersonal violence in our study (weapon assault, physical assault, and sexual assault) were only associated with substance misuse (posterior probability ≥70%) for Latinx participants. Conclusion: The relational nature of interpersonal/violent traumas may make them particularly salient for Latinx people where interpersonal relationships are prioritized. These types of traumas may also be viewed as an extension of discrimination and exclusion, two longstanding, intractable issues for people of color in the US, making them even more damaging. Furthermore, lack of resources may limit options for coping, resulting in substance use problems.
