The female crack users: Higher rates of social vulnerability in Brazil

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.

HIV and Substance Use in Latin America: A Scoping Review

This scoping review aims to explore the interplay between substance use (SU) and HIV in Latin America (LA). Database searches yielded 3481 references; 196 were included. HIV prevalence among people who used substances (PWUS) ranged from 2.8–15.2%. SU definitions were variable throughout studies, and thus data were not easily comparable. In 2019, only 2% of new HIV infections were attributed to injection drug use (IDU) in LA. Factors associated with HIV among PWUS included being female, IDU and homelessness, and PWUS were likely to engage in risky sexual behaviors, start antiretroviral treatment late, have poor adherence, have treatment failure, be lost to follow-up, have comorbidities, and experience higher mortality rates and lower quality of life, as has been reported in PLWH with SU in other regions. Five intervention studies were identified, and only one was effective at reducing HIV incidence in PWUS. Interventions in other regions have varying success depending on context-specific characteristics, highlighting the need to conduct more research in the LA region. Though progress has been made in establishing SU as a major concern in people living with HIV (PLWH), much more is yet to be done to reduce the burden of HIV and SU in LA.

Sex differences in brain regional homogeneity during acute abstinence in cocaine use disorder

There are significant sex differences in the clinical characteristics of cocaine use disorder (CUD). As this is a brain disorder that involves changes in functional connectivity, we investigated the existence of sex differences among people with CUD and controls. We used a data‐driven method comparing males (n = 20, CK‐M) and females with CUD (n = 20, CK‐F) and healthy controls (20 males, HC‐M and 20 females, HC‐F). The participants undertook a resting‐state functional magnetic resonance imaging exam. Regional homogeneity (ReHo) was performed to identify group and sex differences. Persons with CUD of both sexes presented lower ReHo parameters than controls, especially within the parietal lobule. Males with CUD showed higher ReHo than females in three right‐side brain areas: postcentral gyrus, putamen and fusiform gyrus. It was found that abstinence symptoms severity was associated with lower ReHo values in the right postcentral gyrus and the right fusiform gyrus. Participants with CUD exhibited altered ReHo parameters compared to controls, similar to what is found in ageing‐related disorders. Our data also indicate that cocaine has sex‐specific effects on brain functioning when analysing ReHo.

The Perceptions of Women About Their High Experience of Using Crack Cocaine

INTRODUCTION

The aim of this study was to explore the perceptions of women about their experience in using crack cocaine, discussing their motivations for using it and the repercussions in their lives.

OBJECTIVE

To investigate these experiences, a qualitative exploratory study was conducted, using the inductive thematic analyses of the content.

METHODS

Eight female crack cocaine users took part in this study. They were assessed by a semi-structured interview, addressing the crack cocaine use experience. Four main themes emerged in the interviews: (1) crack cocaine "high" experience; (2) symptoms related to crack cocaine use; (3) circumstances of crack cocaine use; and (4) crack cocaine use consequences.

RESULTS

The main perceptions reported by the users were related to a feeling of being disconnected to the world preceded by a pleasant experience, especially during the first moments of use. They revealed that the drug fulfills a key role of coping strategy to handle with negative thoughts, emotions or life experiences. An important influence of social issues was reported in relation to the onset of crack cocaine use. Negative consequences and significant impact on their lives appeared in their reports, regarding the loss of family ties, involvement with prostitution, traumatic experiences and violence.

CONCLUSION

Taking together all women's perceptions suggests that beyond the positive immediate rewarding effect, the maintenance of use might be related to the dissociative experience and self-medication role, acting as negative reward by relieving of negative life experiences that, in turn, are both cause and consequence of the drug use.

Hepatitis E Virus in People Who Use Crack-Cocaine: A Cross-Sectional Study in a Remote Region of Northern Brazil

People who use crack-cocaine (PWUCC) have numerous vulnerabilities and pose a challenge to health and social assistance services. The exposure to pathogens and risk situations occur differently according to each individual, region and social group. This study identified the presence, genotypes and factors associated with hepatitis E virus (HEV) exposure among a community-recruited cohort of 437 PWUCC in northern Brazil. Epidemiological information was collected through community-based assessments and interviews. Thereafter, blood and fecal samples were collected and tested for HEV using an immunoenzymatic assay, and the genotype was identified by PCR. Logistic regressions were used to identify the risk factors independently associated with exposure to HEV. In total, 79 (18.1%) PWUCC were exposed to HEV: 73 (16.7%) for IgG and six for IgG + IgM. HEV RNA was detected in six fecal samples and in two blood samples from PWUCC with IgM + IgG. Subtype 3c was identified in all of the samples. The factors associated with exposure to HEV were low monthly income, unstable housing (e.g., homelessness), crack-cocaine use ≥40 months, and the shared use of crack-cocaine equipment. The current study provides unique initial insights into HEV status and risk factors among PWUCC in a remote area in Brazil, with diverse implications for urgently improved diagnosis, prevention, and treatment intervention needs.

Percepções de Profissionais sobre Atendimentos em Saúde para Mulheres Usuárias de Crack

Resumo As percepções dos profissionais de saúde que atendem mulheres usuárias de crack podem auxiliar no aprimoramento dos atendimentos. Assim, este estudo objetivou compreender essas percepções. Se trata de um estudo qualitativo, com 33 participantes divididos em três grupos focais submetidos à análise temática. Estabeleceram-se dois eixos centrais: a) usuárias de crack e b) serviços de saúde. Posteriormente, identificaram-se oito temas e seis subtemas. No primeiro eixo destacaram-se: características das usuárias, ausência de rede de apoio, violência, estigma de gênero, prostituição e comorbidades clínicas. No segundo ressaltaram-se as dificuldades na articulação entre os serviços e questões a serem aprimoradas, como: prevenção na atenção básica, motivação dos profissionais, serviços específicos para mulheres, especificidades da gestação e combate ao estigma. A partir dos resultados, foram identificados e discutidos os desafios e as potencialidades que se dão nos atendimentos de mulheres usuárias de crack.

Women and substance use disorders in low- and middle-income countries: A call for advancing research equity in prevention and treatment

Although the prevalence of substance use disorders (SUDs) is higher among men, women with SUDs in low- and middle-income countries (LMICs) face unique challenges. Poverty and adversity, inequality of women, and disparities in access to treatment and prevention services exacerbate biological, psychological and social correlates of substance use disorders for women living in low-resource settings. Increasing the inclusion of women in research has long been a goal, though even high income countries struggle to achieve parity. In LMICs, women with SUDs are often neglected from global research due to underreporting and the disproportionate focus of global substance use research on men. We will discuss risk factors for SUDs that are particularly relevant for women residing in LMICs in order to gain insight into neglected areas of research and opportunities for prevention and treatment.

Crack users and violence. What is the relationship between trauma, antisocial personality disorder and posttraumatic stress disorder?

TITLE

Crack users and violence. What is the relationship between trauma, antisocial personality disorder and posttraumatic stress disorder?

BACKGROUND

Crack use is frequently related to severe social and psychiatric conditions including Antisocial Personality Disorder (ASPD) and Posttraumatic Stress Disorder (PTSD). Social vulnerabilities increase the frequency of traumatic exposure. The relationship of trauma and psychiatric disorders among crack users is still unclear.

OBJECTIVES

To describe the characteristics of crack users with ASPD and to verify of the association between ASPD and PTSD, ASPD and each type of traumatic event and the temporality of these events.

METHODS

Data from a multicenter cross-sectional sample of 733 crack users under treatment in six Brazilian capitals was obtained via interviews with Addiction Severity Index (ASI) 6 and Mini International Neuropsychiatric Interview (MINI). Demographic characteristics, psychiatric diagnosis and trauma history were examined. Descriptive and bivariate analyses were used to assess the relationship between the studied variables.

RESULTS

More than 80% of crack users with ASPD and >65% without this diagnosis report traumatic experiences. The prevalence of PTSD disorder among those with ASPD (47.3%) is lower than among those without (52.7%) this diagnosis. The traumatic experiences occur either before or after the first episode of drug use.

CONCLUSIONS

The high prevalence of ASPD and PTSD among crack users and their frequent exposure to severe traumatic events was verified as well as the fact that they are often victims and sometimes perpetrators of violence illustrating the complexity of the relationships between crack use, trauma and comorbidities.

Sex-based differences in multidimensional clinical assessments of early-abstinence crack cocaine users

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.

Effects of DRD2 splicing-regulatory polymorphism and DRD4 48 bp VNTR on crack cocaine addiction

There is evidence that dopamine receptors D2 (DRD2) and D4 (DRD4) polymorphisms may influence substance use disorders (SUD) susceptibility both individually and through their influence in the formation of DRD2-DRD4 heteromers. The dopaminergic role on the vulnerability to addiction appears to be influenced by sex. A cross-sectional study with 307 crack cocaine addicts and 770 controls was conducted. The influence of DRD2 rs2283265 and DRD4 48 bp VNTR in exon 3 variants, as well as their interaction on crack cocaine addiction susceptibility and severity were evaluated in women and men separately. An association between the DRD2 T allele and crack cocaine addiction was found in women. In this same group, interaction analysis demonstrated that the presence of DRD2-T allele and concomitant absence of DRD4-7R allele were associated with risk for crack cocaine addiction. No influence of DRD2 and DRD4 variants was observed in men regarding addiction severity. This study reinforces the role of dopaminergic genes in externalizing behaviors, especially the influence of DRD2-DRD4 interaction on SUD. This is the fourth sample that independently associated the DRD2-DRD4 interaction with SUD itself or related disorders. In addition, our findings point out to a potential difference of dopaminergic neurotransmission across sex influencing addiction susceptibility.

Ideação suicida e consumo de drogas ilícitas por mulheres

Resumo Objetivo Analisar a relação entre ideação suicida e consumo de drogas ilícitas em mulheres. Métodos Estudo analítico realizado com 369 mulheres atendidas em Unidades Básicas de Saúde utilizando para investigação do consumo de drogas ilícitas o Non-Student Drugs Use Questionnaire e para investigação da ideação suicida o Self-Reporting Questionnaire. Resultados Verificou-se que existe associação entre ideação suicida e o uso de tranquilizantes sem prescrição médica (p=0,005), de solventes (p=0,006) e de maconha (p=0,003). O consumo de tranquilizantes aumenta em 2,7 vezes (IC=1,372-5,608) as chances de as mulheres terem ideação suicida quando comparadas com aquelas que não fazem uso das referidas drogas, bem como pelo uso de solventes em 10,1 vezes (IC=2,197-46,967) e o uso de maconha em 3,3 vezes (IC=1,865-13,900). Conclusão Os indicadores produzidos apontam que uso de drogas ilícitas pelas mulheres tem implicação grave e, portanto, necessita de intervenções efetivas que devem focalizar, sobretudo, na prevenção da ideação suicida, uma vez que a progressão dessa ideação poderá convergir para desfechos trágicos que incluem tentativa de suicídio, automutilação e suicídio.
