Abstract
BACKGROUND Cocaine-use disorder (CUD) has been associated with early life adversity and activated cellular immune responses. Women are most vulnerable to complications from chronic substance disorders, generally presenting an intense feeling of abstinence and consuming significant drug amounts. Here, we investigated neutrophil functional activities in CUD, including the formation of neutrophil extracellular traps (NETs) and related intracellular signalling. We also investigated the role of early life stress in inflammatory profiles. METHODS Blood samples, clinical data, and history of childhood abuse or neglect were collected at the onset of detoxification treatment of 41 female individuals with CUD and 31 healthy controls (HCs). Plasma cytokines, neutrophil phagocytosis, NETs, intracellular reactive oxygen species (ROS) generation, and phosphorylated protein kinase B (Akt) and mitogen-activated protein kinases (MAPK)s were assessed by flow cytometry. RESULTS CUD subjects had higher scores of childhood trauma than controls. Increased plasma cytokines (TNF-α, IL-1β, IL-6, IL-8, IL-12, and IL-10), neutrophil phagocytosis, and production of NETs were reported in CUD subjects as compared to HC. Neutrophils of CUD subjects also produced high levels of intracellular ROS and had more activated Akt and MAPKs (p38/ERK), which are essential signalling pathways involved in cell survival and NETs production. Childhood trauma scores were significantly associated with neutrophil activation and peripheral inflammation. CONCLUSION Our study reinforces that smoked cocaine and early life stress activate neutrophils in an inflammatory environment.

Abstract
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.

Wouldes TA, Crawford A, Stevens S, Stasiak K. Evidence for the Effectiveness and Acceptability of e-SBI or e-SBIRT in the Management of Alcohol and Illicit Substance Use in Pregnant and Post-partum Women. Front Psychiatry 2021; 12:634805. [PMID: 34025470 PMCID: PMC8131659 DOI: 10.3389/fpsyt.2021.634805] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 03/17/2021] [Indexed: 12/12/2022] Open
Abstract
Alcohol and illicit psychoactive drug use during pregnancy have increased worldwide, putting women and their children's health and development at risk. Multiple drug use, comorbid psychiatric disorders, sexual and physical abuse are common in women who use alcohol and drugs during pregnancy. The effects on the mother include poor reproductive and life-long health, legal, family, and social problems. Additionally, the exposed child is at increased risk of long-term physical health, mental health, and developmental problems. The stigma associated with substance use during pregnancy and some clinicians' reticence to inquire about substance use means many women are not receiving adequate prenatal, substance abuse, and mental health care. Evidence for mHealth apps to provide health care for pregnant and post-partum women reveal the usability and effectiveness of these apps to reduce gestational weight gain, improve nutrition, promote smoking cessation and manage gestational diabetes mellitus, and treat depression and anxiety. Emerging evidence suggests mHealth technology using a public health approach of electronic screening, brief intervention, or referral to treatment (e-SBIRT) for substance use or abuse can overcome the typical barriers preventing women from receiving treatment for alcohol and drug use during pregnancy. This brief intervention delivered through a mobile device may be equally effective as SBIRT delivered by a health care professional in preventing maternal drug use, minimizing the effects to the exposed child, and providing a pathway to therapeutic options for a substance use disorder. However, larger studies in more diverse settings with women who have co-morbid mental illness and a constellation of social risk factors that are frequently associated with substance use disorders are needed.

Abstract
Resumo Este artigo problematiza os sentidos construídos por profissionais de Consultórios na Rua (CnaR) sobre o consumo de crack por mulheres e suas implicações às práticas de cuidado. Pesquisa qualitatitava realizada junto a quatro equipes de CnaR (eCnaR) que atuam em três territórios do município do Rio de Janeiro, totalizando 25 profissionais. Produzidos a partir de grupos focais, os dados empíricos apontam para a diversidade de sentidos na compreensão do crack, entendido como a “droga da morte” ou a ‘pedra da felicidade’.A discussão e a análise dos dados revelam que o gênero é incorporado de modo controverso no cotidiano dos serviços: mesmo que os discursos sinalizem para diferenças nos padrões de consumo de crack entre homens e mulheres, no acesso e uso dos serviços psicossociais e na forma de obtenção da droga, as mulheres continuam sendo pensadas pela sua capacidade reprodutiva. Apontam, ainda, que mesmo nos serviços da rede assistencial de saúde, usuárias de crack são estigmatizadas: por serem mulheres que consomem crack e pela situação de rua. Sinalizam que impera na organização da rede de serviços o ideário da mulher-mãe. Advoga-se pelo imperativo da incorporação do referencial empírico-analítico dos estudos de gênero na política de atenção à saúde de usuários de crack.

Abstract
BACKGROUND Evidence in different countries suggest an association between sex work and drug use. In the Dominican Republic an estimated 60,000-100,000 women work in the sex industry. However, little is known about their drug use behaviors. OBJECTIVE To characterize the burden of drug use and examine correlates of these behaviors among female sex workers in the Dominican Republic. METHODS Data for this analysis comes from a cross-sectional study among key populations at risk for HIV. A community sample of female sex workers (N = 389) was recruited using passive and active recruitment strategies. Participants completed a behavioral survey between 2015 and 2016. Logistic regression models were constructed to examine predictors of drug use. RESULTS Protective factors against marijuana and crack or cocaine use included being heterosexual, having a higher level of education, regular employment, and fewer male sexual partners. Increased odds of crack or cocaine use were associated with incarceration, having slept in a place not meant for human habitation in the last six months, and having ever lived in a batey (a community around a sugar mill where workers and their families live). Participants that used marijuana were generally younger, while those that used crack or cocaine were older. CONCLUSIONS Our findings highlight characteristics of the social and economic environment that require further research to optimize prevention and care strategies for this population. Public health interventions are needed that address drug use, sexual risk-taking, and helping female sex workers and their families achieve a healthy life.

Abstract
OBJECTIVE To explore and describe sociodemographic characteristics, crack consumption patterns, and psychiatric comorbidities of female crack users receiving treatment at therapeutic communities. METHODS This was a cross-sectional, descriptive, quantitative study. Forty-six women who abstained from crack use were assessed using a sociodemographic questionnaire, the Mini-Mental State Examination (MMSE), the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and a profile of crack use questionnaire. Descriptive statistical analyses were conducted. RESULTS Participants had a mean age of 31.02 years (standard deviation [SD] = 7.73), most were single (76.1%), white (67.4%) and had complete or incomplete elementary education (43.5%). Before treatment, 65.2% of the women reported using crack every day; 46.3% smoked between 10 to 30 crack rocks per week. Mean treatment time was 63.56 days (SD = 75.85), with a mean of 80.41 days of abstinence (SD = 74.52) and 3.37 previous treatments (SD = 5.49). Mean age upon crack use initiation was 22.61 years (SD = 8.06), and the most frequent motivation to start using crack was curiosity (78.3%). The mean lifetime duration of crack use was 82.26 months (SD = 74.76), and the physical complications most frequently reported were weight loss (93.5%), followed by sleep problems (87%). In this study, the most prevalent psychiatric diagnoses were major depressive episode (60.87%), followed by post-traumatic stress disorder (52.17%) and generalized anxiety disorder (13.07%). CONCLUSIONS Overall, a pattern of high consumption of crack was observed. The results show a high frequency of mood and anxiety disorders, with the highest frequencies found for major depressive episode and post-traumatic stress disorder.

Abstract
Crack cocaine use disorder (CUD) has been related to sex differences. This work aimed to compare the severity of drug use and the severity of other negative related outcomes in males and females with CUD. A total of 1344 inpatients (798 males and 546 females) with crack cocaine use disorder (CUD) were evaluated by a detailed multidimensional clinical assessment, including addiction severity and trauma exposure. Linear regression predicted higher drug use severity (β = 0.273, p < 0.001) and more problems in domains related to childcare issues (β = 0.321), criminal involvement (β = 0.108), work-related problems (β = 0.281) and social support impairments (β = 0.142) for females, all with p < 0.001. Alcohol problems were predicted to be higher in males (β = -0.206, P < 0.001). Females had higher rates of other mental disorders, particularly trauma and stress-related disorders (OR: 3.206, CI: 2.22, 4.61). Important sex differences also emerged in trauma history and HIV infection prevalence. CUD has a more severe clinical presentation among females facing early abstinence. Sex differences in the CUD course indicate the need for consideration of sex-specific interventions and research.

Abstract
Globally, cocaine use increased by 7%-18.2 million people in 2016 or 0.4% of the world population aged 15-64. In 2016, over 34 million (0.7%) people aged 15-64 used amphetamines and a further 0.4% used MDMA (Ecstasy). Women of child bearing age worldwide are increasingly using and becoming dependent on stimulants; and are, in turn, more vulnerable to sexually transmitted diseases, sexual violence, unplanned pregnancies and mental health problems. Stimulant use during pregnancy increases obstetric complications for the mother, increases the rate of preterm birth and decreases birth weight, length and head circumference for the exposed infant. No consistent signs of neonatal abstinence syndrome requiring pharmacological treatment have been identified for cocaine or methamphetamine, however, infants exposed to one or both drugs exhibit disorganized neurobehaviour at birth. Increased efforts worldwide are needed to determine the extent of maternal stimulant use and to prevent or identify and treat substance use early during pregnancy.

Abstract
OBJECTIVE To verify the association between the profile of women who seek specialized treatment for the use of psychoactive substances, their treatment adherence time and the types of substance used. METHOD A retrospective cohort with data from medical records of women who sought care at a referral service for the use of psychoactive substances. RESULTS The final sample consisted of 411 medical records. A significant association was observed between unemployment (p<0.000), living in the streets/homeless shelters (p=0.003), having HIV/AIDS (p=0.004) and the type of substance used. The best predictors for the treatment adherence time were being a cocaine and crack user (OR=0.22), having family members who use illegal substances (OR=0.36) and reporting suicidal ideation (OR=2.7). CONCLUSION The sociodemographic and epidemiological factors of the women in this study are associated with the use of psychoactive substances. The therapeutic strategies developed for this group should take into account the risk stratification, seeking comprehensive and individualized care. Persistent approaches to include family members in the treatment, especially of those who present problems related to the use of psychoactive substances should be considered.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection is related with several liver diseases such as cirrhosis and hepatocellular carcinomas, leading to more than 0.5 million deaths every year and to a great global burden. It is known that injection drug users show a high prevalence of HCV infection, being considered a risk group for this disease. Cocaine users seem to be in greater risk than other drug users, and several hypotheses for this association are being studied. AIM To review data on HCV infection in cocaine users, taking into consideration the relevance of the different routes of drug administration and other risk behaviors. METHODS This was a narrative review performed in the main scientific databases. RESULTS AND CONCLUSION Data suggest that cocaine use could be associated with HCV infection due to the specificities of cocaine consumption pattern, even in those subjects who do not inject drugs, in addition to other risky behaviors, such as tattooing and unprotected sex. Injectable cocaine users seem to be more susceptible to contamination than users who do not inject drugs. However, evidence is pointing to the possibility of infection by sharing drug paraphernalia other than syringes. Moreover, specific immune system impairments caused by cocaine use are also being linked with HCV infection susceptibility, persistence and increased pathological effects.

[From evidence to action: challenges for the Brazilian Unified National Health System in offering pre-exposure prophylaxis (PrEP) for HIV to persons with the greatest vulnerability]. CAD SAUDE PUBLICA 2018; 34:e00206617. [PMID: 30043853 DOI: 10.1590/0102-311x00206617] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2017] [Accepted: 05/02/2018] [Indexed: 12/12/2022] Open
Abstract
Pre-exposure prophylaxis (PrEP) has been considered a promising strategy for controlling the global HIV epidemic. However, it is necessary to translate the knowledge accumulated from clinical trials and demosntration studies to the reality of health services and the groups most vulnerable to infection in order to achieve broad coverage with PrEP. The article proposes a reflection on this challenge, focusing on three dimensions: users of prophylaxis, with an emphasis on the contexts of sexual practices and the potential exposures to HIV; the advantages of prophylaxis as compared to other methods and the challenges for protective and safe use; and health services, considering the organizational principles to ensure greater success in the supply and incorporation of PrEP as part of combination prevention strategies. The following principles were analyzed: uniqueness of care, freedom of choice and non-hierarchization of prevention methods, sexual risk management, scheduling flexibility, and complementary and multidisciplinary care. These principles can foster organization of the health service and care, facilitating linkage and retention in care. Some comments were offered on the relative incompatibility between the existing structure of services and the Brazilian Ministry of Health guidelines for offering PrEP. The conclusion was that the success of PrEP as a public health policy depends on two essential factors: ensuring that health services are culturally diverse settings, free of discrimination, and the intensification of community-based interventions, including social networks, in order to reduce inequalities in access to PrEP and health services as a whole.

Abstract
Brazil has the largest cocaine market in South America, and crack cocaine use is closely associated with HIV-1 infection. This study investigated the prevalence, risk factors, and HIV-1 subtypes, including recombinant forms and mutations associated with drug resistance, among crack cocaine users in Central-West Brazil. We recruited 600 crack cocaine users admitted to a referral hospital in Goiânia for psychiatric disorders. The participants were interviewed; blood samples were collected for anti-HIV-1/2 serological screening. HIV-1 pol gene sequences (entire protease [PR] and partial reverse transcriptase [RT]) were obtained from plasma RNA. HIV-1 subtypes, recombinant viruses, transmitted drug resistance (TDR), and secondary drug resistance mutations were investigated. The median participant age was 30 years (range, 18-68 years); most were male, single, unemployed, and of mixed races. Among them, 2.8% (17/600) were HIV-1 positive: 2.2% of men (11/507) and 6.5% of women (6/93). The main predictors of HIV-1 seropositivity were a sexual partner with HIV infection, irregular condom use, and previous homelessness. HIV-1 pol sequences (12/17) indicated the predominance of subtype B (n = 7), followed by recombinant forms FPR/BRT (n = 1) and BPR/FRT (n = 2) and subtypes F1 (n = 1) and C (n = 1). TDR prevalence was 58.3% (7/12). Isolates from two participants showed mutations associated with resistance to nucleoside reverse transcriptase inhibitors (NRTI) only (M41L, T125C, T125F, M184V), while an isolate from one patient who had received antiretroviral therapy (ART) since 2008 had a mutation associated with resistance to non-NRTI (G190S). Five isolates had secondary mutations to protease inhibitors (K20M, L10V, L33I, A71T, A71V). In conclusion, the findings of HIV-1 circulation, TDR to NRTI, and secondary mutations to protease inhibitors in ART-naïve crack cocaine users support the importance of monitoring this population in regions far from the epicenter of the HIV epidemic.

Abstract
The article comprises a narrative review of the scientific literature, aiming to identify and discuss the contexts of vulnerability and social exclusion faced by users of crack cocaine and other substances who live on the sidelines of society in the Brazilian and international context. The paper summarizes insights from different theoretical frameworks, focusing on an integrated perspective of substance use and abuse, with an emphasis on the use of crack and its inter-relationships with social vulnerability, marginalization, social exclusion and deviation. In a first step, broad aspects of qualitative research on drugs are outlined. The subsequent section highlights issues associated with exclusion and social vulnerability of crack users, followed by an assessment of the main associations mentioned in the literature on drug use and criminal involvement. Finally, the concept of "sidelines of society" is discussed, as exemplified by situations and events experienced by users of crack and other substances, as mentioned in the literature.

Abstract
The objective of this study was to investigate risk behaviors for sexually transmitted infections (STIs) in noninjecting drug users (NIDUs), using STI diagnosis history as an indicator. A cross-sectional study was conducted in 323 NIDUs of two facilities for alcohol and/or drug dependence treatment in the Goiás State, Central Brazil. All participants were interviewed about risk behaviors and STI history. Multivariable analysis was performed in order to identify predictors of STIs. Adjusted prevalence ratio (APR) with confidence intervals of 95% was obtained using a Poisson regression model. Prevalence of self-reported STIs in the previous 12 months was 25.4% (95% confidence interval [95% CI]: 21.0-30.4%). A multivariable model verified that age (APR: 1.01; 95% CI: 1.00-1.01), sexual contact with partners diagnosed with STIs (APR: 1.27; 95% CI: 1.12-1.45) and injecting drug users (IDUs) (APR: 1.14; 95% CI: 1.14; 95% CI: 1.01-1.31), exchange sex for money and/or drugs (APR: 1.12; 95% CI: 1.02-1.21), and a history of sexual violence (APR: 1.04; 95% CI: 1.04-1.32) were predictors of STIs. Elevated rates of STI history and risk behaviors were observed in NIDUs, supporting the vulnerability of this group for these infections. Public policies and health outreach should be intensified in this population, principally regular STI testing of individuals in treatment for drug dependence and their sexual partners.

Abstract
BACKGROUND The aim of this study was to compare sociodemographic characteristics, patterns of drug use, and risky sexual behaviour among female and male users of crack cocaine. METHODS Between 2012 and 2013, we conducted a cross-sectional study of 919 crack cocaine users (783 men and 136 women) in Central Brazil using face-to-face interviews. Blood samples were collected to test for syphilis. The Chi-Square Automatic Interaction Detector (CHAID) was used to explore the differences between genders. We implemented two models: the first model included previous incarceration and variables related to patterns of drug use, and the second model included variables related to sexual risky behaviours and syphilis exposure. RESULTS Women consumed more crack cocaine than men on a regular basis; however, poly-drug use was more common among men. More women than men reported exchanging sex for money and/or drugs and inconsistent condom use during sexual intercourse; women also reported more sexual partners. In addition, the frequency of sexual violence was higher for women than men. A higher proportion of women than men were positive for syphilis (27.2% vs. 9.2%; p < 0.001). The CHAID decision tree analysis identified seven variables that differentiated the genders: previous incarceration, marijuana use, daily crack cocaine consumption, age at first illicit drug use, sexual violence, exchange of sex for money and/or drugs, and syphilis exposure. CONCLUSION Our findings demonstrate a difference in patterns of crack cocaine consumption and sexual risky behaviours between genders, thus indicating a need for gender-specific interventions in this population.

Abstract
BACKGROUND Studies indicate high rates of criminal behavior, violent activities, and legal problems among illicit drug users (IDU) in Brazil. The aim of this study was to estimate the prevalence and factors associated with criminal behavior among IDU undergoing treatment for chemical dependency in Central Brazil. METHODS Cross-sectional study carried out with IDU undergoing treatment for chemical dependence. Data were collected by means of face-to-face interviews and analyzed using logistic regression. RESULTS Of the total participants (n = 274), 46.7%, 15.7%, and 10.9% reported involvement in robbery, drug trafficking and homicide, respectively. Robbery was associated with young age, withdrawal symptoms, prison record, sex work, and crack use, while drug trafficking was associated with young age, low education, and marijuana use. Homicides were associated with cocaine and marijuana use. CONCLUSION The results show high rates of criminal behavior among drug users, demonstrating associations between socio-demographic and behavioral characteristics, illicit drug use, and practices of illegal activities. These variables must be considered when planning programs and policies to reduce harm related to drug use and abuse.

Abstract
RESUMO Este artigo visa investigar como se conformam, no Brasil e internacionalmente, as abordagens ao uso prejudicial do crack e outras drogas. Foi realizada uma revisão crítica da literatura acerca do padrão de consumo do crack e os fatores a ele relacionados com busca sistemática em bases eletrônicas no período de 2010 a 2016. Foram analisados 37 artigos por autor, ano, país do estudo, metodologia; padrão de consumo de crack e fatores individuais e contextuais relativos a esse uso. Conclui-se que a abordagem ao uso de drogas deve estar focada na perspectiva da redução de danos, na promoção da autonomia e dos direitos humanos, e não na utopia de eliminação do consumo e da produção de drogas.

Abstract
Objective: To compare the working memory (WM) performance of young adult crack-cocaine dependent users, healthy older adults, and a control group of healthy young adults. Methods: A total of 77 female participants took part in this study: 26 young adult crack-cocaine dependent users (CRK), 19 healthy older adults (HO), and 32 healthy younger adults (HC). All participants completed the N-back verbal task. Results: A multivariate analysis of covariance was performed. The model included education, income, and medication use as covariates. A group effect (F6,140 = 7.192, p < 0.001) was found. Post-hoc analyses showed that the performance of the CRK and HO groups was reduced compared to the HC group in two N-back conditions. No differences between the HO and CRK groups on WM performance were found. Conclusions: CRK participants perform similar to HO participants on a WM task, despite the well-known effects of age on WM and the young age of CRK. These data point to a possible parallel between cognitive declines associated with crack use and developmental aging.

Abstract
BACKGROUND Early life stress (ELS) and addiction are related to age-related diseases and telomere shortening. However, the role of telomere length (TL) in crack cocaine addiction remains unknown. The purpose of this study was to investigate the TL in a sample of crack cocaine dependent-women who reported an ELS history and in a community-based sample of elderly women as a reference group for senescence. METHODS This study included treatment seeking crack cocaine dependents women (n=127) and elderly women without a psychiatric diagnosis (ELD, n=49). The crack cocaine sample was divided in two groups according to their Childhood Trauma Questionnaire (CTQ) scores: presence of history of childhood abuse and neglect (CRACK-ELS) and absence of ELS history (CRACK). TL was assessed by T/S ratio obtained from peripheral blood DNA using quantitative PCR assay. RESULTS CRACK and CRACK-ELS subjects exhibited shortened TL in comparison to the ELD group, despite their younger age. Among crack cocaine sample, CRACK-ELS group had significantly shorter telomeres than the CRACK group. Correlation analysis within crack cocaine group indicated that TL was negatively correlated with emotional abuse scores. CONCLUSIONS These results support previous findings associating telomere shortening with both ELS and drug addiction. This study suggests new evidence of a distinct biological phenotype for drug-dependent women with ELS. The results support the biological senescence hypothesis underpinning ELS experience.

Abstract
Crack cocaine addicted inpatients that present more severe withdrawal symptoms also exhibit higher rates of depressive symptoms. There is strong evidence that the identification of genetic variants in depression is potentialized when reducing phenotypic heterogeneity by studying selected groups. Since depression has been associated to dysregulation of the hypothalamic-pituitary-adrenal axis, this study evaluated the effects of SNPs in stress-related genes on depressive symptoms of crack cocaine addicts at early abstinence and over the detoxification treatment (4th, 11th and 18th day post admission). Also, the role of these SNPs on the re-hospitalization rates after 2.5 years of follow-up was studied. One hundred eight-two women were enrolled and eight SNPs in four genes (NR3C2, NR3C1, FKBP5 and CRHR1) were genotyped. A significant main effect of NR3C1-rs41423247 was found, where the C minor allele increased depressive symptoms at early abstinence. This effect remained significant after 10,000 permutations to account for multiple SNPs tested (P=0.0077). There was no effect of rs41423247 on the course of detoxification treatment, but a slight effect of rs41423247 at late abstinence was detected (P=0.0463). This analysis suggests that the presence of at least one C allele is worse at early abstinence, while only CC genotype appears to increase depressive symptoms at late abstinence. Also, a slight effect of rs41423247 C minor allele increasing the number of re-hospitalizations after 2.5 years was found (P=0.0413). These findings are in agreement with previous studies reporting an influence of rs41423247 on sensitivity to glucocorticoids and further elucidate its resulting effects on depressive-related traits.

Transactional Sex among Noninjecting Illicit Drug Users: Implications for HIV Transmission. ScientificWorldJournal 2016; 2016:4690628. [PMID: 27648467 PMCID: PMC5018331 DOI: 10.1155/2016/4690628] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Revised: 07/04/2016] [Accepted: 07/11/2016] [Indexed: 02/05/2023] Open
Abstract
Noninjecting illicit drug users (NIDUs) present high risk for HIV infection, due especially to transactional sex. This study aimed to estimate the prevalence and risk factors for transactional sex among NIDUs in the Southwest region of Goiás State, Central Brazil. The prevalence of self-reported transactional sex was 22.8%. Prevalence in women and men was 52.7% and 16.8%, respectively, a significant difference (p < 0.001). Crack use and history of sexually transmitted infections (STI) were risk factors for transactional sex in men. Homelessness, crack use, sex under the influence of drugs, and history of sexual violence were risk factors for transactional sex in women. A high prevalence of transactional sex was observed among NIDUs. This risk behavior may contribute to the high rates of HIV among this population and their social networks and in the general population.

Abstract
Problem Early diagnosis of infections with human immunodeficiency virus (HIV) is needed – especially among key populations such as sex workers, transgender people, men who have sex with men and people who use drugs. Approach The Brazilian Ministry of Health developed a strategy called Viva Melhor Sabendo (“live better knowing”) to increase HIV testing among key populations. In partnership with nongovernmental organizations (NGOs), a peer point-of-care testing intervention, using an oral fluid rapid test, was introduced at social venues for key populations at different times of the day. Local setting Key populations in Brazil can have 40 times higher HIV prevalence than the general population (14.8% versus 0.4%). Relevant changes Legislation was reinterpreted, so that oral fluid rapid tests could be administered by any person trained in rapid testing by the health ministry. Between January 2014 and March 2015, 29 723 oral fluid tests were administered; 791 (2.7%) were positive. Among the key populations, transgender people had the greatest proportion of positive results (10.7%; 172/1612), followed by men who declared themselves as commercial sex workers (8.7%; 165/1889) and men who have sex with men (4.8%; 292/6055). Lessons learnt The strategy improved access to HIV testing. Testing done by peers at times and locations suitable for key populations increased acceptance of testing. Working with relevant NGOs is a useful approach when reaching out to these key populations.

Abstract
BACKGROUND Although previous studies have shown that both adolescence and drug addiction can influence risk-taking and decision-making processes, the underlying mechanisms remain unclear. Specifically, there is a lack of evidence as to whether these conditions could affect deliberative and affective processes involved in risk taking, such as feedback learning and valuation of profits and risk. OBJECTIVES The objectives were to compare the role of feedback and the use of information in risk-taking behavior between female crack cocaine users and adolescents. Additionally, we aimed to investigate whether sensation seeking, impulsivity, depressive and anxiety symptoms, executive functioning, and working memory performance could explain differences in risk-taking behavior. METHOD This is a quasi-experimental study comparing 27 low-income adult female crack cocaine users (CU) to 18 female adolescents (AD) within two conditions (no-feedback or delayed-feedback) of the Columbia Card Task (CCT). In order to investigate CCT reference values for adult females, we also included 20 female non-drug-users with regular education and income as a reference group (RG). RESULTS A similar pattern of risk-taking behavior was found between CU and AD within the CCT no-feedback condition. When delayed feedback was provided, AD exhibited a similar pattern of risk-taking behavior in the no-feedback condition, while CU showed a reduction of risk-taking behavior. Both groups exhibited higher risk taking than the RG within the CCT no-feedback condition, but only the AD group showed higher risk-taking behavior within the CCT feedback condition. Depressive symptom severity and working memory deficits were associated with higher risk-taking behaviors in CU. Executive functioning deficits were associated with higher risk-taking behavior in AD. CONCLUSIONS Adult female crack cocaine users and female adolescents took similar risks during risky decision-making scenarios where feedback about their own performance was absent. However, when participants were provided with such feedback, it modulated risk-taking behaviors in crack cocaine users but not in adolescents.

Low prevalence, low immunization and low adherence to full hepatitis B vaccine scheme and high-risk behaviors among crack cocaine users in central Brazil. J Infect Public Health 2016; 10:76-83. [PMID: 27026240 DOI: 10.1016/j.jiph.2016.02.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2015] [Revised: 02/18/2016] [Accepted: 02/20/2016] [Indexed: 01/25/2023] Open
Abstract
Crack cocaine users represent a target group for hepatitis B vaccination. We evaluate the HBV epidemiology, immunization status and compliance with a super-accelerated vaccination schedule among in-treatment crack cocaine users in central Brazil. Six hundred in-treatment crack cocaine users were interviewed, and serum samples were tested for HBV markers. A super-accelerated vaccination schedule of HBV vaccine was offered to all susceptible crack cocaine users. In total, 7.0% of those tested had at least one positive marker of HBV exposure. Age, use of crack cocaine through improvised pipe, exchange of sex for money/drugs and previous sexually transmitted infections (STIs) were predictors of HBV exposure. One hundred six (17.7%) individuals showed a serological profile of hepatitis B vaccination. Of these, 54.7% were less than 25 years old, and only 13% of individuals were more than 35 years old. Although 91.8% of crack users accepted the first vaccine dose, only 21.7% received all three doses. Of the 23 crack cocaine users who agreed to have their vaccine response evaluated, 78.3% developed protective anti-HBs titers. Premature termination of treatment was the most common reason for not receiving the full vaccine series. Despite the low prevalence of HBV exposure among in-treatment crack cocaine users in central Brazil, the low rate of immunization and the high frequency of high-risk behaviors highlight the potential for crack users to acquire and disseminate this infection and therefore maintain the viral reservoir. Health practitioners need to keep this in mind, taking advantage of all opportunities to access this population and vaccinate against HBV.

Abstract
Objetivo Este estudo teve como objetivo adaptar a Cocaine Selective Severity Assessment (CSSA) para o português do Brasil e verificar as propriedades psicométricas do instrumento em uma amostra de usuárias de crack. Métodos Após as etapas de tradução e adaptação, 125 mulheres usuárias de crack, internadas em uma unidade pública de desintoxicação, foram avaliadas. Para caracterização da amostra e análise das validades concorrente, de construto e preditiva, foram utilizados os seguintes instrumentos: SCID-I, ASI-6, BDI-II e CCQ-B. Resultados A análise fatorial exploratória identificou cinco fatores, com níveis adequados de consistência interna tanto para os fatores quanto para o escore geral da CSSA. Quanto à validade concorrente, a CSSA vai ao encontro de instrumentos já utilizados na clínica e em pesquisas. Em relação à validade de construto e preditiva, a CSSA pode ser sensível ao declínio dos sintomas de abstinência durante o processo de desintoxicação do crack. Conclusões Nossos achados foram além da tradução e adaptação da CSSA, proporcionando testes de validade e sugerindo que a CSSA é um instrumento confiável na avaliação dos sintomas de abstinência do crack.

Abstract
O aumento do uso de crack tem se constituído em um desafio para a saúde pública no Brasil. Os objetivos deste artigo são identificar como se constituem as relações de gênero no cotidiano dos usuários de crack; e analisar a dinâmica que permeia a construção destas relações que envolvem troca e poder. Estudo qualitativo, descritivo, exploratório, de orientação fenomenológica. Dados coletados com usuários de crack em situação de rua, na comunidade de Manguinhos, no Rio de Janeiro. Realizados oito grupos focais (n = 31) e duas entrevistas individuais, entre Junho e Agosto de 2011. Nos grupos, os relatos dos rapazes e moças investigados diferiram quanto ao estabelecimento dos vínculos de afeto; no papel atribuído ao crack como operador na mediação de conflitos; no uso do corpo como moeda de troca/prostituição e na geração e cuidado da prole. Foram observados alguns deslocamentos com relação aos acordos tradicionais e hierárquicos de gênero. O estudo das relações estabelecidas na pesquisa revela que não é possível apontar para algozes ou vítimas. O que surge nas análises é um universo plural e fluido, em permanente construção, com deslizamentos que privilegiam ora as mulheres e ora os homens.
