Substance use patterns, sociodemographics, and health profiles of harm reduction service recipients in Burlington, Vermont.

BACKGROUND: Understanding current substance use practices is critical to reduce and prevent overdose deaths among individuals at increased risk including persons who use and inject drugs. Because individuals participating in harm reduction and syringe service programs are actively using drugs and vary in treatment participation, information on their current drug use and preferred drugs provides a unique window into the drug use ecology of communities that can inform future intervention services and treatment provision. METHODS: Between March and June 2023, 150 participants in a harm reduction program in Burlington, Vermont completed a survey examining sociodemographics; treatment and medication for opioid use disorder (MOUD) status; substance use; injection information; overdose information; and mental health, medical, and health information. Descriptive analyses assessed overall findings. Comparisons between primary drug subgroups (stimulants, opioids, stimulants-opioids) of past-three-month drug use and treatment participation were analyzed using chi-square and Fisher's exact test. RESULTS: Most participants reported being unhoused or unstable housing (80.7%) and unemployed (64.0%) or on disability (21.3%). The drug with the greatest proportion of participants reporting past three-month use was crack cocaine (83.3%). Fentanyl use was reported by 69.3% of participants and xylazine by 38.0% of participants. High rates of stimulant use were reported across all participants independent of whether stimulants were a participant's primary drug. Fentanyl, heroin, and xylazine use was less common in the stimulants subgroup compared to opioid-containing subgroups (p < .001). Current- and past-year MOUD treatment was reported by 58.0% and 77.3% of participants. Emergency rooms were the most common past-year medical treatment location (48.7%; M = 2.72 visits). CONCLUSIONS: Findings indicate high rates of polysubstance use and the underrecognized effects of stimulant use among people who use drugs-including its notable and increasing role in drug-overdose deaths. Crack cocaine was the most used stimulant, a geographical difference from much of the US where methamphetamine is most common. With the increasing prevalence of fentanyl-adulterated stimulants and differences in opioid use observed between subgroups, these findings highlight the importance and necessity of harm reduction interventions (e.g., drug checking services, fentanyl test strips) and effective treatment for individuals using stimulants alongside MOUD treatment.

Preliminary investigation of the administration of biperiden to reduce relapses in individuals with cocaine/crack user disorder: A randomized controlled clinical trial.

BACKGROUND: Several studies have demonstrated that ACh modulates the dopaminergic circuit in the nucleus accumbens, and its blockade appears to be associated with the inhibition of the reinforced effect or the increase in dopamine caused by cocaine use. The objective of this study was to evaluate the effect of biperiden (a muscarinic receptor antagonist with a relatively higher affinity for the M1 receptor) on crack/cocaine use relapse compared to a control group that received placebo. METHODS: This study is a double-blind, randomized, placebo-controlled clinical trial. The intervention group received 2 mg of biperiden, 3 times a day, for a period of 3 months. The control group received identical placebo capsules, at the same frequency and over the same period. All participants were followed for a period of six months. RESULTS: The sample comprised 128 people, with 61 in the control group and 67 in the biperiden group. Lower substance consumption was observed in the group that received biperiden treatment two (bT2 = -2.2 [-3.3; -1.0], p < 0.001) and six months (bT4 = -6, 2 [-8.6; -3.9], p < 0.001) after the beginning of the intervention. The biperiden group had a higher latency until a possible first day of consumption, in the same evaluation periods (bT2 = 0.26 [0.080; 0.44], p = 0.004; bT4 = 0.63 [0.32; 0.93], p < 0.001). CONCLUSIONS: Despite the major limitations of the present study, the group that received biperiden reduced the number of days of cocaine/crack use and showed an increase in the latency time for relapse. More studies are needed to confirm the utility of this approach.

Safe inhalation pipe provision (SIPP): protocol for a mixed-method evaluation of an intervention to improve health outcomes and service engagement among people who use crack cocaine in England.

BACKGROUND: Over 180,000 people use crack cocaine in England, yet provision of smoking equipment to support safer crack use is prohibited under UK law. Pipes used for crack cocaine smoking are often homemade and/or in short supply, leading to pipe sharing and injuries from use of unsafe materials. This increases risk of viral infection and respiratory harm among a marginalised underserved population. International evaluations suggest crack pipe supply leads to sustained reductions in pipe sharing and use of homemade equipment; increased health risk awareness; improved service access; reduction in injecting and crack-related health problems. In this paper, we introduce the protocol for the NIHR-funded SIPP (Safe inhalation pipe provision) project and discuss implications for impact. METHODS: The SIPP study will develop, implement and evaluate a crack smoking equipment and training intervention to be distributed through peer networks and specialist drug services in England. Study components comprise: (1) peer-network capacity building and co-production; (2) a pre- and post-intervention survey at intervention and non-equivalent control sites; (3) a mixed-method process evaluation; and (4) an economic evaluation. Participant eligibility criteria are use of crack within the past 28 days, with a survey sample of ~ 740 for each impact evaluation survey point and ~ 40 for qualitative process evaluation interviews. Our primary outcome measure is pipe sharing within the past 28 days, with secondary outcomes pertaining to use of homemade pipes, service engagement, injecting practice and acute health harms. ANTICIPATED IMPACT: SIPP aims to reduce crack use risk practices and associated health harms; including through increasing crack harm reduction awareness among service providers and peers. Implementation has only been possible with local police approvals. Our goal is to generate an evidence base to inform review of the legislation prohibiting crack pipe supply in the UK. This holds potential to transform harm reduction service provision and engagement nationally. CONCLUSION: People who smoke crack cocaine in England currently have little reason to engage with harm reduction and drug services. Little is known about this growing population. This study will provide insight into population characteristics, unmet need and the case for legislative reform. TRIAL REGISTRATION: ISRCTN12541454  https://doi.org/10.1186/ISRCTN12541454.

Making Harm Reduction More Accessible: Fentanyl Test Strip Awareness and Attitudes among Emergency Department Patients Who Use Drugs.

BACKGROUND: Fentanyl test strips (FTS) are a harm reduction method for people to test their drugs for fentanyl. Ideal points for FTS distribution have not been identified. Many people who use drugs have frequent contact with the Emergency Department (ED). We piloted FTS distribution in two urban hospital EDs. METHODS: Between June-December 2021 in Philadelphia, PA, patients with past 30-day drug use completed a survey about drug use, fentanyl attitudes, and FTS; then offered FTS and a brief training. Survey data were analyzed using SPSS for bivariate statistics. RESULTS: Patients (n = 135) were primarily White (68.1%) and male (72.6%). Participants regularly interacted with substance use (57.8%) and benefits coordination (49.6%) services. The most common drugs used were heroin/fentanyl (68.9%), crack cocaine (45.2%) and cannabis (40.0%). Most (98.5%) had heard of fentanyl though few (18.5%) had ever used FTS. Across most drug types, participants were concerned about fentanyl. All accepted FTS training and distribution. Few (9.6%) were somewhat or very concerned about having FTS if stopped by police and this number varied by race (7.6% of White people were somewhat or very concerned, compared to 12.8% of Black people). Most participants were already engaged in risk reduction practices. DISCUSSION: FTS are a widely desired harm reduction tool to facilitate informed decision-making, and non-harm reduction locations are potentially feasible and acceptable distribution sites. Given regular contact with EDs and social services across the sample, FTS should be offered at non-harm reduction locations that come into frequent contact with people who use drugs.

Peripheral neurotrophin levels during controlled crack/cocaine abstinence: a systematic review and meta-analysis.

Cocaine/crack abstinence periods have higher risk of relapse. Abstinence as initial part of the recovery process is affected by learning and memory changes that could preserve the addictive cycle. To further understand how the interruption of cocaine/crack consumption affects neurotrophin level we performed the present systematic review and meta-analysis following the PRISMA statement (number CRD42019121643). The search formula was conducted in PubMed, Web of Science, Embase, ScienceDirect, and Google Scholar databases. The inclusion criterion was cocaine use disorder in 18 to 60-year-old people, measuring at least one neurotrophin in blood before and after a controlled abstinence period. Studies without pre-post design were excluded. Five investigations had nine different reports, four of them were subjected to a meta-analysis (n = 146). GRADE risk of bias method was followed. Individual studies reported increased peripheral brain derived neurotrophic factor (BDNF) after abstinence, evidence pooled by Hedge's g showed no significant change in BDNF after abstinence. Relevant heterogeneity in the length of the abstinence period (12-32 days), last cocaine/crack consumption monitoring and blood processing were detected that could help to explain non-significant results. Further improved methods are suggested, and a potential BDNF augmentation hypothesis is proposed that, if true, would help to understand initial abstinence as a re-adaptation period influenced by neurotrophins such as the BDNF.

Correlates of Stimulant Use among People Who Use Heroin Undergoing Treatment in Out-Patient Facilities in France, 2010-2020.

Background: Polydrug use has been implicated in driving a "fourth wave" of the overdose crisis in North America, specifically through concurrent use of stimulants and opioids, especially fentanyl. In France, however, heroin has historically been and remains the easiest-to-access opioid, accounting for most drug treatment demand. Whether similar polydrug use is increasing in Western Europe remains understudied, despite severe health implications and potential inadequate public health responses.Methods: We take advantage of a nation-wide dataset containing information on all patients serviced in treatment centers in France from 2010 to 2020. We conduct Poisson regression to determine the main predictors of stimulant use among people who use heroin (PWUH) and opioids (PWUO) generally.Results: Heroin remains the primary opioid within drug treatment in France. A decreasing number of out-patients seeking treatment for heroin use has been accompanied by an increasing trend of stimulant use over time, most commonly with powder cocaine. Our results suggest a significant increase of crack cocaine use among the most vulnerable PWUH. Concurrent use of stimulants among PWUH was positively associated with use of alcohol, cannabis, unprescribed psychotropics and hallucinogens, and negatively with tobacco. Similar results were found for all in-treatment PWUO.Conclusions: Our results uncover heterogeneity in the profiles of PWUH that should be fully acknowledged to ensure better efficiency in substance use clinical practices and policy, while simultaneously drawing attention to trends in concurrent opioid-stimulant use outside North America. We advocate for an extension of the generalized risk framework and its implementation in prevention programs.

Overamped: Stimulant Use and HIV Pathogenesis.

PURPOSE OF REVIEW: In the era of HIV treatment as prevention (TasP), more clarity is needed regarding whether people with HIV who use stimulants (i.e., methamphetamine, powder cocaine, and crack cocaine) display elevated HIV viral load and greater immune dysregulation. RECENT FINDINGS: Although rates of viral suppression have improved in the TasP era, stimulant use was independently associated with elevated viral load in 23 of 28 studies included in our review. In the 12 studies examining other HIV disease markers, there was preliminary evidence for stimulant-associated alterations in gut-immune dysfunction and cellular immunity despite effective HIV treatment. Studies generally focused on documenting the direct associations of stimulant use with biomarkers of HIV pathogenesis without placing these in the context of social determinants of health. Stimulant use is a key barrier to optimizing the effectiveness of TasP. Elucidating the microbiome-gut-brain axis pathways whereby stimulants alter neuroimmune functioning could identify viable targets for pharmacotherapies for stimulant use disorders. Examining interpersonal, neighborhood, and structural determinants that could modify the associations of stimulant use with biomarkers of HIV pathogenesis is critical to guiding the development of comprehensive, multi-level interventions.

The utilization and delivery of safer smoking practices and services: a narrative synthesis of the literature.

BACKGROUND: Providing sterile drug smoking materials to people who use drugs can prevent the acquisition of infectious diseases and reduce overdose risk. However, there is a lack of understanding of how these practices are being implemented and received by people who use drugs globally. METHODS: A systematic review of safer smoking practices was conducted by searching PubMed, PsycInfo, Embase for relevant peer-reviewed, English-language publications from inception or the availability of online manuscripts through December 2022. RESULTS: Overall, 32 peer-reviewed papers from six countries were included. 30 studies exclusively included people who use drugs as participants (n = 11 people who use drugs; generally, n = 17 people who smoke drugs, n = 2 people who inject drugs). One study included program staff serving people who use drugs, and one study included staff and people who use drugs. Sharing smoking equipment (e.g., pipes) was reported in 25 studies. People who use drugs in several studies reported that pipe sharing occurred for multiple reasons, including wanting to accumulate crack resin and protect themselves from social harms, such as police harassment. Across studies, smoking drugs, as opposed to injecting drugs, were described as a crucial method to reduce the risk of overdose, disease acquisition, and societal harms such as police violence. Ten studies found that when people who use drugs were provided with safer smoking materials, they engaged in fewer risky drug use behaviors (e.g., pipe sharing, using broken pipes) and showed improved health outcomes. However, participants across 11 studies reported barriers to accessing safer smoking services. Solutions to overcoming safer smoking access barriers were described in 17 studies and included utilizing peer workers and providing safer smoking materials to those who asked. CONCLUSION: This global review found that safer smoking practices are essential forms of harm reduction. International policies must be amended to help increase access to these essential tools. Additional research is also needed to evaluate the efficacy of and access to safer smoking services, particularly in the U.S. and other similar countries, where such practices are being implemented but have not been empirically studied in the literature.

Prevalence of fentanyl in methamphetamine and cocaine samples collected by community-based drug checking services.

BACKGROUND: Overdose deaths involving stimulants and opioids simultaneously have raised the specter of widespread contamination of the stimulant supply with fentanyl. METHODS: We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 2021-June 2023). Samples from 77 harm reduction programs and clinics originated in 25 US states. Sample donors reported expected drug and physical descriptions. Substances were identified by gas chromatography-mass spectrometry. Negative binomial models were used to calculate fentanyl prevalence, adjusting for potential confounders related to sample selection. We also examined if xylazine changed donors' accuracy of detecting fentanyl. RESULTS: We analyzed 718 lab-confirmed samples of methamphetamine (64%) and cocaine (36%). The adjusted prevalence of fentanyl was 12.5% (95% CI: 2.2%, 22.9%) in powder methamphetamine and 14.8% (2.3%, 27.2%) in powder cocaine, with notable geographic variation. Crystalline forms of both methamphetamine (Chisq=57, p<0.001) and cocaine (Chisq=18, p<0.001) were less likely to contain fentanyl: less than 1% of crystal methamphetamine (2/276) and no crack cocaine (0/53). Heroin was present in 6.6% of powder cocaine samples. Xylazine reduced donors' ability to detect fentanyl, with correct classification dropping from 92% to 42%. CONCLUSIONS: Fentanyl was detected primarily in powder forms of methamphetamine and cocaine. Recommended interventions include expanding community-based drug checking, naloxone and fentanyl test strip distribution for people who use stimulants , and supervised drug consumption sites. New strategies to dampen variability in street drug composition are needed to reduce inadvertent fentanyl exposure.

Salivary protein candidates for biomarkers of oral disorders in people with a crack cocaine use disorder.

The use of cocaine and its main derivative, crack, can cause some systemic effects that may lead to the development of some oral disorders. To assess the oral health of people with a crack cocaine use disorder and identify salivary protein candidates for biomarkers of oral disorders. A total of 40 volunteers hospitalized for rehabilitation for crack cocaine addiction were enrolled; nine were randomly selected for proteomic analysis. Intraoral examination, report of DMFT, gingival and plaque index, xerostomia, and non-stimulated saliva collection were performed. A list of proteins identified was generated from the UniProt database and manually revised. The mean age (n=40) was 32 (±8.88; 18-51) years; the mean DMFT index was 16±7.70; the mean plaque and gingival index were 2.07±0.65 and 2.12±0.64, respectively; and 20 (50%) volunteers reported xerostomia. We identified 305 salivary proteins (n=9), of which 23 were classified as candidate for biomarkers associated with 14 oral disorders. The highest number of candidates for biomarkers was associated with carcinoma of head and neck (n=7) and nasopharyngeal carcinoma (n=7), followed by periodontitis (n=6). People with a crack cocaine use disorder had an increased risk of dental caries and gingival inflammation; less than half had oral mucosal alterations, and half experienced xerostomia. As possible biomarkers for 14 oral disorders, 23 salivary proteins were identified. Oral cancer and periodontal disease were the most often associated disorders with biomarkers.

Drug use patterns and factors related to the use and discontinuation of medications for opioid use disorder in the age of fentanyl: findings from a mixed-methods study of people who use drugs.

BACKGROUND: Medications for opioid use disorder (MOUD; methadone, buprenorphine, naltrexone) are the most effective treatments for OUD, and MOUD is protective against fatal overdoses. However, continued illegal drug use can increase the risk of treatment discontinuation. Given the widespread presence of fentanyl in the drug supply, research is needed to understand who is at greatest risk for concurrent MOUD and drug use and the contexts shaping use and treatment discontinuation. METHODS: From 2017 to 2020, Massachusetts residents with past-30-day illegal drug use completed surveys (N = 284) and interviews (N = 99) about MOUD and drug use. An age-adjusted multinomial logistic regression model tested associations between past-30-day drug use and MOUD use (current/past/never). Among those on methadone or buprenorphine (N = 108), multivariable logistic regression models examined the association between socio-demographics, MOUD type; and past-30-day use of heroin/fentanyl; crack; benzodiazepines; and pain medications. Qualitative interviews explored drivers of concurrent drug and MOUD use. RESULTS: Most (79.9%) participants had used MOUD (38.7% currently; 41.2% past), and past 30-day drug use was high: 74.4% heroin/fentanyl; 51.4% crack cocaine; 31.3% benzodiazepines, and 18% pain medications. In exploring drug use by MOUD history, multinomial regression analyses found that crack use was positively associated with past and current MOUD use (outcome referent: never used MOUD); whereas benzodiazepine use was not associated with past MOUD use but was positively associated with current use. Conversely, pain medication use was associated with reduced odds of past and current MOUD use. Among those on methadone or buprenorphine, separate multivariable logistic regression models found that benzodiazepine and methadone use were positively associated with heroin/fentanyl use; living in a medium-sized city and sex work were positively associated with crack use; heroin/fentanyl use was positively associated with benzodiazepine use; and witnessing an overdose was inversely associated with pain medication use. Many participants qualitatively reported reducing illegal opioid use while on MOUD, yet inadequate dosage, trauma, psychological cravings, and environmental triggers drove their continued drug use, which increased their risk of treatment discontinuation and overdose. CONCLUSIONS: Findings highlight variations in continued drug use by MOUD use history, reasons for concurrent use, and implications for MOUD treatment delivery and continuity.

Serum BDNF levels increase during early drug withdrawal in alcohol and crack cocaine addiction.

Brain-derived neurotrophic factor (BDNF) is involved in several drug-induced brain neuroadaptations. The impact of withdrawal from substances that have different neurological mechanisms on BDNF levels is unclear. Our goal was to compare serum BDNF levels in inpatients with alcohol or crack cocaine use disorders during the early withdrawal period, and to evaluate the association with substance-related outcomes. We performed a follow-up study with 101 men under detoxification treatment (drug preference: alcohol [n = 37] and crack cocaine [n = 64]). Blood samples were collected on the 1st and 15th days of hospitalization to measure serum BDNF levels. Serum BDNF levels increased during the early stage of withdrawal (28.2 ± 10.0 vs. 32.6 ± 13.3, p < 0.001), similarly in individuals with alcohol and crack cocaine use. In the alcohol group, BDNF levels on the 15th day of hospitalization were negatively correlated with age (r = -0.394, p = 0.023). Delta BDNF levels were also negatively correlated with BDNF on the 1st day of hospitalization (p = 0.011). No significant correlation was found regarding substance-related outcomes. This is the first study to compare BDNF levels in alcohol and crack cocaine users undergoing similar treatment conditions. These findings could be related to clinical improvement after abstinence or even to drug withdrawal itself, decreasing neuronal injury. Furthermore, age may be a crucial factor, hindering the recovery of neuroplasticity in alcohol users.

Transgenerational Cycle of Traumatization and HIV Risk Exposure among Crack Users.

The aim of this manuscript is to understand the impact of childhood sexual abuse on the development of Post-Traumatic Stress Disorder (PTSD), Human Immunodeficiency Virus (HIV) exposure. and parental neglect in crack cocaine users, considering the role of gender. This study is a secondary database analysis of a sample from a multicenter cross-sectional study with 715 crack cocaine users receiving outpatient treatment in public mental health networks in six Brazilian capitals. Prevalence ratios were estimated by Poisson regression. In crack cocaine users with childhood sexual abuse, traumatic experiences seem to remain fixed through the development of Post Traumatic Stress Disorder (PTSD) in adulthood. Crack cocaine users with childhood abuse and PTSD in adulthood showed more sexual risk behaviors, including outcomes such as HIV (PR = 3.6 p < 0.001 for childhood abuse and PR = 3.7 p < 0.001 for PTSD). Furthermore, this traumatic trajectory affects the functional ability of crack cocaine users, especially women, to work thus impacting their inclusion and sense of social belonging. Such a chain seems to be reflected in the establishment of a circle of transgenerational transmission, to the extent that subjects with a history of abuse and PTSD reported more parental neglect towards their children. This study reinforces the importance of preventive public policies regarding early socio-emotional vulnerabilities and the need to support families, especially women, to avoid HIV and self-destructive outcomes such as crack cocaine use.

Cuidado em saúde mental com gestantes usuárias de crack / Mental health care with pregnant crack users / Cuidadode salud mental con mujeres embarazadas que utilizan crack

Neste manuscrito, apresentamos uma pesquisa cujo objetivo foi o de compreender como vem sendo produzidas as práticas de cuidado às gestantes usuárias de crack nos serviços de saúde de um município do interior do Rio Grande do Sul. Este estudo de abordagem qualitativa, foi realizado junto a dois serviços públicos, o Programa de Redução de Danos (PRD) e o Centro de Atenção Psicossocial para Álcool e outras Drogas (CAPSad III), com cinco mulheres voluntárias para a pesquisa. As histórias de vida foram reconstruídas a partir de suas narrativas e também de profissionais da saúde que proveram algum tipo de cuidado às participantes. Após a exposição das histórias, refletimos sobre três pistas importantes para pensarmos as práticas de cuidado às gestantes usuárias de crack: saúde mental, uso de drogas e interseccionalidade; direitos humanos, hierarquias reprodutivas e concepções de maternidade; e as práticas de cuidado em saúde. Observamos que as concepções dos profissionais acerca da maternidade direcionam as práticas de cuidado em saúde, caracterizando-se como um cuidado no espectro da saúde materno-infantil, e não um cuidado direcionado à saúde da mulher. Conhecer as demandas de cuidado dessas mulheres é essencial para que possamos pensar em práticas de saúde pautadas pela clínica ampliada. (AU)

In this manuscript, we present a research whose objective was to understand how the practicesof care to the pregnant women users of crack have been being produced in the services of health in a town of Rio Grande do Sul. This study of qualitative approach it was developed jointly to two public services, the Program of Reduction of Harms (PRH) andPsychosocial Care Centers Alcohol and other Drugs (CAPSad), with five voluntary women for the research. The life histories were rebuilt starting from their narratives and also of health's professionals that provided some care to the participants.After exposing the stories, we reflected on three important clues to think about care practices for pregnant women who use crack: mental health, drug use and intersectionality; human rights, reproductive hierarchies and conceptions of motherhood; and health care practices. We observed that the professionals' conceptions about maternity guide health care practices, characterized as care in the spectrum of maternal and child health, and not care directed at women's health.Knowing the care demands of these women is essential for us to think about health practices guided by the expanded clinic.

Conocer las demandas de atención de estas mujeres es fundamental para que pensemos en las prácticas de salud guiadas por la clínica ampliada. (AU)

Assessment of cognitive functioning using the Mini Mental State Examination in men with Alcohol and Crack Cocaine Use Disorder.

INTRODUCTION: Consumption of substances has been associated with cognitive impairment. The Mini Mental State Examination (MMSE) is an easy-to-apply screening tool used to assess cognitive functions. OBJECTIVES: To evaluate the cognitive performance of individuals with alcohol (AUD) and/or crack cocaine use disorder (CUD) and polysubstance use using the MMSE and to investigate the impact of substance use profile and the moderation effect of educational level on MMSE performance. METHODS: Cross-sectional study with 508 adult male inpatients diagnosed with substance use disorders (245 with AUD, 85 with CUD, and 178 with polysubstance use). Cognitive performance was assessed using the MMSE scale (total and composite scores). RESULTS: Individuals with AUD had worse total MMSE scores and scored worse for all three MMSE components compared to individuals with polysubstance use (p < 0.001, oral/written language comprehension, p < 0.001, attention/memory, and p = 0.007, motor functions). MMSE scores were positively correlated with educational level (p < 0.017), but were not associated with age, recent drug use, or years of drug use. Educational level moderated the impact of substance use on MMSE performance, especially total score and composite language comprehension score. Individuals with a low educational level (≤ 8 years) had worse performance than those with a high educational level (≥ 9 years), mainly in individuals with AUD (p < 0.001). DISCUSSION: Individuals with a low educational level and alcohol use are more prone to present cognitive impairment than crack cocaine users, especially involving language aspects. Better-preserved cognitive function could impact treatment adherence and might guide the decision of therapeutic strategies.

Does the Association Between Stimulant use and High Risk Sexual Behavior Vary by Injection Drug Use, Sexual Minority Status, or HIV Infection Status? A Meta-analysis.

There is strong evidence linking stimulant use, namely methamphetamine use, to sexual risk behavior among sexual minority men (SMM); we do not, however, have a good understanding of this relationship among other at-risk populations. In this study, we systematically reviewed associations between stimulant use (i.e., methamphetamine, crack cocaine, cocaine) and sexual risk behaviors among populations facing elevated risk of HIV transmission and acquisition (i.e., SMM, people who inject drugs (PWID), and people living with HIV/AIDS (PLWH)). Random-effects meta-analyses and sensitivity analyses that included crude and adjusted estimates separately were conducted to evaluate the impact of potential confounding variables. The results showed strong relationships between stimulant use and condomless sex, transactional sex, and multiple sexual partners. Results were broadly consistent when analyses were stratified by type of stimulant (methamphetamine, crack cocaine, and other stimulants) and risk group. Sensitivity analyses with confounding variables did not greatly impact results. The results indicate that stimulant use is associated with numerous sexual risk behaviors regardless of risk group, suggesting prevention efforts focused on reducing methamphetamine-related HIV risk should target a range of at-risk populations.

ADHD and addictive behavior in crack-cocaine users.

BACKGROUND: Crack consumption is a major public health issue in Martinique with a poor prognosis. A preliminary study has found a high prevalence of history of childhood ADHD (C-ADHD) in crack users. OBJECTIVE: To determine the prevalence of C-ADHD and adult ADHD (A-ADHD) in crack users and their potential associations with substance use behavior. METHODS: All consecutive patients consulting in the public academic hospital covering 376,000 inhabitants were included in the present study and received a comprehensive battery measuring addictive behavior, psychiatric and somatic comorbidities. C-ADHD groups and A-ADHD groups were defined with the Wender-Utah Rating Scale-25 and the Brown ADD Rating Scale, respectively. Impulsivity was evaluated with the Barratt Impulsiveness Scale (BIS-11). FINDINGS: In total, 111 participants were evaluated. Among them, 50 (45%) were classified in the C-ADHD group and 20 (18%) in the A-ADHD group. Compared to the patients without ADHD, those with ADHD were found to have higher impulsivity (C-ADHD: BIS total score 67.90 (10.1) vs. 63.28 (10.5), P=0.021, BIS attentional score 17.5 (3.6) vs. 15.3 (3.4), P=0.002, A-ADHD: BIS total score 75.1 (11.3) vs. 63.4 (9.2), P<0.001, BIS motor impulsivity 26.9 (5.3) vs. 22.6 (4.3), P<0.001, BIS attentional score 19.3 (3.3) vs. 15.6 (3.5), P<0.001, BIS planification 28.9 (5.7) vs. 25.10 (4.7), P=0.003). Fifty percent of A-ADHD patients were found with high impulsivity vs. 15% of patients without A-ADHD (P<0.001). However, ADHD was not associated with more severe addictive behavior or history of legal consequences. INTERPRETATION: ADHD prevalence is high in cocaine-crack users and associated with increased impulsivity. However, neither ADHD nor impulsivity explains addictive behaviors or legal consequences.

Early discharge predictors among inpatients crack cocaine users.

INTRODUCTION: High rates of early hospital discharge are often observed in crack cocaine users and are related to adverse outcomes and increased public spending. This study evaluated clinical and sociodemographic factors associated with early treatment discharge among crack users. METHODS: The sample comprised 308 men diagnosed with crack cocaine use disorder (crack only), aged 18 to 65 years, admitted between 2013 and 2017 to a male-only hospital unit to treat substance use disorders. Sociodemographic and clinical data were obtained using the Addiction Severity Index, 6th version, and a Sociodemographic Questionnaire. RESULTS: Early discharge (within 7 days) was significantly associated with lack of own income, insufficient family support, being single, and recent homelessness. Regarding drug use, lower treatment retention was related to younger age of crack use onset, recent alcohol use, and nicotine use. Factors such as age, skin color, and educational level showed no relation to the outcome. CONCLUSION: Our findings suggest that presence of characteristics verifiable at the time of admission may be related to crack users' treatment retention. Identification of these factors can contribute to target interventions in order to improve treatment adherence in crack cocaine users.

Sobre dias em que me senti sem ar: desassossegos do pesquisar / On days when i felt breathless: unrest of search / Sobre días que me sentí sin aliento: disurbios de investigación

Resumo Conceitos como o de alteridade, encontro de saberes, polifasia cognitiva, o princípio de familiaridade e de representações sociais operaram na complexa tarefa de compreender como os encontros entre profissionais e usuários sustentavam e/ou transformavam as práticas de acolhimento. Entretanto, a experiência da minha pesquisa de doutorado me levou a questionar os próprios conceitos utilizados da Teoria das Representações Sociais. Ao final do ensaio, após discutir aspectos teórico-metodológicos, o princípio de familiaridade e a questão da tensão e dos afetos nas representações sociais, espero evidenciar como o movimento provocado pelo encontro com usuários e profissionais de uma Rede de Atenção Psicossocial levou-me a questionar pontos essenciais da teoria: o papel domesticador das representações, a forma ainda estática de evidenciar os fenômenos, a separação entre um sujeito que representa e o objeto representado e a dificuldade em usar suas ferramentas conceituais para acompanhar processos me fazem repensar meu lugar e minha função de pesquisador.

Abstract Concepts such as alterity, encounter of knowledge, cognitive polyphasia, the principle of familiarity and the very concept of social representations operated in the complex task of understanding how the encounters between professionals and users supported and / or transformed user embracement practices. However, the experience of my doctoral research led me to question the very concepts used in the Theory of Social Representations. At the end of the essay, after discussing theoretical and methodological aspects, the principle of familiarity and the issue of tension and affects in social representations, I hope to show how the movement caused by the encounter with users and professionals of a Psychosocial Care Network, led me to question essential points of the theory: the domesticating role of representations, the still static way of showing phenomena, the separation between a subject that represents and the object represented and the difficulty in using their conceptual tools to accompany processes makes me rethink my place and role as a researcher.

Resumen Conceptos como la alteridad, el encuentro de saberes, la polifasia cognitiva, el principio de familiaridad y el concepto mismo de representaciones sociales operaron en la compleja tarea de comprender cómo los encuentros entre profesionales y usuarios apoyaron y / o transformaron las prácticas de acogimiento. Sin embargo, la experiencia de mi investigación doctoral me llevó a cuestionar los propios conceptos utilizados en la Teoría de las Representaciones Sociales. Al final del ensayo, después de discutir aspectos teóricos y metodológicos, el principio de familiaridad y el tema de tensión y afectos en las representaciones sociales, Espero mostrar cómo el movimiento provocado por el encuentro con usuarios y profesionales de una Red de Atención Psicosocial, me llevó a cuestionar puntos esenciales de la teoría: el rol domesticador de las representaciones, la forma todavía estática de mostrar los fenómenos, la separación entre un sujeto que representa y el objeto representado y la dificultad para utilizar sus herramientas conceptuales para acompañar procesos, me hace repensar mi lugar y rol como investigador.

(Sobre)viver na rua: narrativas das pessoas em situação de rua sobre a rede de apoio / (About) living on the street: narratives of homeless people about the support network / (Sobre)vivir en la calle: narrativas de personas en situación de calle sobre la red de apoyo

A população em situação de rua (PSR), em seu cotidiano, se relaciona com diferentes pessoas, grupos e/ou coletivos ligados à execução das políticas públicas, às organizações não governamentais, familiares ou a membros da sociedade civil. Pensar nessas dinâmicas de trabalho, cooperação e auxílio remete a pensar sobre uma rede de apoio que constrói estratégias com essa população. Tendo presente essas problematizações, este estudo teve como objetivo analisar as narrativas das pessoas em situação de rua sobre como é produzida sua rede de apoio. Para tanto, foi realizado um estudo qualitativo, de orientação etnográfica, sendo utilizada a observação participante, registros em diário de campo e entrevistas narrativas. Participaram seis pessoas em situação de rua que recebem alimentação ofertada por projetos sociais em uma cidade do interior do Rio Grande do Sul. Os dados produzidos foram analisados a partir da Análise Temática. As análises expressam as especificidades das narrativas das trajetórias de vida associadas à chegada às ruas e à composição de uma rede de apoio na rua. Ao conhecer como se produz e opera essa rede de apoio, a partir das narrativas das pessoas em situação de rua, problematiza-se a complexidade dessa engrenagem e o desafio de produzir ações integradas entre as diferentes instâncias da rede. Nisso, destaca-se a potencialidade de práticas que levem conta à escuta, ao diálogo e à articulação na operacionalização de políticas públicas atentas às necessidades dessa população.(AU)

The street population, in their daily lives, relates to different people, groups and/or collectives linked to the execution of public policies, to non-governmental organizations, family members, or to members of civil society. Thinking about these dynamics of work, cooperation, and assistance leads to thinking about a support network that builds strategies with this population. Having these problematizations in mind, this study aims to analyze the narratives of homeless people about how their support network is produced. To this end, a qualitative study was carried out, with ethnographic orientation, using participant observation, records in a field diary, and narrative interviews. Participated in the research six homeless people who receive food offered by social projects in a municipality in the interior of Rio Grande do Sul. The data produced were analyzed using the Thematic Analysis. The analyzes express the specifities of the narratives of life trajectories associated with the arrival on the streets and the composition of a support network on the street. By knowing how the support network is produced and operated, the complexity of this gear and the challenge of producing integrated actions between the different instances of the network are problematized. Thus, it highlights the potential of practices that consider listening, dialogue, and articulation in the operationalization of public policies that are attentive to the needs of this population.(AU)

Las personas en situación de calle en su cotidiano se relacionan con distintas personas, grupos y/o colectivos, que están vinculados a la ejecución de políticas públicas, organizaciones no gubernamentales, familiares o miembros de la sociedad civil. Pensar en estas dinámicas de trabajo, cooperación y ayuda nos lleva a una red de apoyo que construye estrategias con estas personas. Teniendo en cuenta esta problemática, este estudio tiene como objetivo analizar las narrativas de las personas en situación de calle acerca de cómo se produce su red de apoyo. Con este fin, se realizó un estudio cualitativo, etnográfico, utilizando observación participante, registros de diario de campo y entrevistas narrativas. Este estudio incluyó a seis personas en situación de calle que reciben alimentos ofrecidos por proyectos sociales en una ciudad del interior de Rio Grande do Sul (Brasil). Se utilizó el Análisis Temático. Los análisis expresan las especificidades de las narrativas de las trayectorias de vida asociadas con la llegada a las calles y la composición de una red de apoyo en la calle. Al saber cómo se produce y opera la red de apoyo, a partir de las narrativas de las personas en la calle, se problematizan la complejidad de este equipo y el desafío de producir acciones integradas entre las diferentes instancias de la red. Destaca el potencial de las prácticas que tienen en cuenta la escucha, el diálogo y la articulación en la implementación de políticas públicas que estén atentas a las necesidades de esta población.(AU)
