Abstract 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.

Objectives: To compare suicide rates observed in Brazil after the onset of the COVID-19 pandemic with the estimated rate based on suicide deaths between 2010 and 2020, and identify sociodemographic variables associated with this outcome. Methods: Ecological time-series study. Data were obtained from Brazilian Unified Health System Department of Information Technology (DATASUS), with the structural break of the data set in March 2020. The number of actual suicides observed and the number of expected suicides if there were no COVID-19 pandemic were analyzed through bayesian structural time series modeling. Results: The overall incidence of suicides in Brazil remained stable after the start of the COVID-19 pandemic compared to what would be expected. However, there was a significant increase in suicide deaths among women (6.9%) and older adult (9.1%). Analysis by macro-regions of the country showed significant increases in suicide deaths in the Center-West (7.4%), Northeast (5.7%), and Southeast (10%). Stratified analyses revealed differences according to age, sex, education, and skin color. Conclusions: Despite stability in the overall number of suicides, this phenomenon occurs heterogeneously among different population groups and regions of Brazil. Rates have increased in populations with a history of poor access to health, which may have been more severely impacted by the pandemic.

Objective: To assess differences in blood inflammatory cytokines between people with alcohol use disorder (AUD) and healthy controls (HC). Methods: Searches were performed from inception through April 14, 2021. Meta-analyses with random-effects models were used to calculate the standardized mean difference ([SMD], 95%CI), and potential sources of heterogeneity were explored trough meta-regressions and subgroup analysis. Results: The meta-analysis included 23 studies on the following 14 cytokines: tumor necrosis factor (TNF)-α, IL-1, IL-1RA, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-13, IL15, interferon (IFN)-γ and sCD14. There were significantly higher concentrations of IL-6 (n=462 AUD and 408 HC; SMD = 0.523; 95%CI 0.136-0.909; p = 0.008) in AUD than HC. No significant differences were found in the other 13 cytokines. Conclusion: We found that IL-6 levels were significantly higher in individuals with AUD than HC and that other cytokines were not altered. This can be explained by the small number of studies, their methodological heterogeneity, and confounding factors (active use, abstinence, quantity, and physical or psychiatric illnesses, for example). Despite a great deal of evidence about alcohol and inflammatory diseases, studies assessing the role of neuroimmune signaling in the development and severity of AUD are still lacking.

Objective: Conduct a systematic review and meta-analysis to evaluate levels of anger among substance users compared to non-user controls and to analyze the possible association between anger and psychoactive substance use (PSU). Methods: The procedures of this review followed the Meta-Analyzes of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Four electronic databases (MEDLINE, EMBASE, BIREME, PsycINFO) were searched. Results: Twelve studies were included in the meta-analysis; 10 used the State-Trait Anger Expression Inventory (STAXI) anger trait subscale and two used the Buss-Perry-Aggression Questionnaire (BPAQ) anger subscale. The sample included 2,294 users of psychoactive substances and 2,143 non-users, all male. The mean difference in anger scale scores between users and non-users was 2.151 (95%CI 1.166-3.134, p ≤ 0.00, inconsistency index [I2] = 98.83) standard deviations. Age and abstinence duration did not moderate the difference in anger between substance users and non-users. Conclusion: Users of psychoactive substances had elevated anger scores compared to non-users, which represents a high risk of relapse. It is suggested that PSU treatment programs include intensive anger management modules, focusing on factors such as dealing with daily stressors, family conflicts, frustrations, and problems.

Abstract Introduction Changes in brain-derived neurotrophic factor (BDNF) have been linked to the neuroadaptative consequences of chronic alcohol use and associated with disease severity and prognosis. Few studies have evaluated the influence of drug withdrawal and clinical and sociodemographic data on BDNF levels in severe alcohol users. Objectives Our goals were (1) to evaluate variation in BDNF levels during alcohol withdrawal and, (2) to assess the influence of putative confounding factors on BDNF levels. Methods Our sample consists of 62 men with alcohol use disorder undergoing a detoxification process. Serum BDNF levels were measured using a commercial sandwich-ELISA kit, at two points: before and after the detoxification period. Results We found an increase in BDNF levels during alcohol withdrawal (25.4±9.6 at admission vs. 29.8±10.2 ng/ml at discharge; p < 0.001), even after controlling for potential confounders (positive family history, number of days between blood sample collections, and age) (Generalized Estimating Equation: coefficient = -4.37, 95% confidence interval [95%CI] -6.3; -2.4; p < 0.001). Moreover, individuals who had first-degree relative with alcohol dependence had smaller increases in BDNF levels than individuals with no family history (14.8 [95%CI -5.3; 35.6] vs. 35.3 [95%CI 15.4; 74.8]; p = 0.005). Conclusions In summary, variation in BDNF levels seems to be influenced by withdrawal in severe alcohol users. A positive family history of alcohol dependence could also be a factor that influences variation in this biomarker.

Abstract The COVID-19 pandemic is unquestionably impacting on the mental health of the population worldwide. Fear of contamination can both increase levels of stress in healthy individuals and intensify psychiatric symptoms in patients with pre-existing conditions, especially obsessive-compulsive disorder (OCD). During the COVID-19 pandemic, the imminent risk of contamination creates a logical need for self-surveillance and hygiene habits. However, this kind of information can have drastic implications for subjects with OCD, since cognitive distortions and compensatory strategies (cleansing rituals) are no longer irrational or oversized – rather, these ideas become legitimate and socially accepted, generating plausible validation for the intensification of compulsive cleaning rituals. Patients who presented remission of OCD symptoms would be more likely to have a relapse, and subclinical patients may scale up and ultimately be diagnosed with OCD due to the reinforcement of their habits, emotions and thoughts.

RESUMO OBJETIVO: Analisar a satisfação de usuários em relação ao acesso, à infraestrutura e à qualidade dos serviços na Atenção Primária à Saúde (APS) no Brasil. MÉTODOS: Estudo transversal com dados de 114.615 usuários vinculados a 30.523 equipes de saúde, obtidos por meio do banco de dados do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). Foram estudadas variáveis independentes relacionadas ao acesso, à infraestrutura e à qualidade dos serviços na APS. O desfecho, satisfação dos usuários, foi mensurado através das variáveis: “se tivesse a opção, mudaria de equipe ou de serviço de saúde” e “recomendaria este serviço de saúde para um amigo ou familiar”. Para avaliar a satisfação de acordo com as variáveis independentes de exposição, foi utilizado o teste Qui-quadrado de Pearson, considerando nível de significância de 5%. Análises descritivas das variáveis foram realizadas através de frequências absoluta (n) e relativa (%). RESULTADOS: A satisfação dos usuários esteve associada às variáveis de acesso (p < 0,001), infraestrutura (p < 0,001) e qualidade dos serviços (p < 0,001) na APS. A proximidade do serviço, atenção à demanda espontânea, escuta e o respeito dos profissionais às singularidades do paciente, assim como a resolutividade dos serviços, sem necessidade de encaminhamentos para outros e a boa infraestrutura, estiveram relacionados com a satisfação dos usuários. CONCLUSÃO: Para a garantia da melhoria da qualidade dos serviços ofertados na APS do Brasil, os aspectos de satisfação dos usuários identificados no presente estudo devem ser considerados na organização e gestão dos serviços.

ABSTRACT OBJECTIVE: To analyze user satisfaction in relation to access, infrastructure and quality of Primary Health Care (PHC) services in Brazil. METHODS: This cross-sectional study was conducted with data from 114,615 users linked to 30,523 health teams, obtained through the database of the Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB —National Program for the Improvement of Access and Quality of Primary Care). Independent variables related to access, infrastructure and quality of services in PHC were studied. The outcome, user satisfaction, was measured using the variables: “if given the option, I would change the staff or health service” and “I would recommend this health service to a friend or family member.” To assess satisfaction according to independent exposure variables, Pearson’s chi-squared test was used, considering a significance level of 5%. Descriptive analyses of the variables were performed using absolute (n) and relative (%) frequencies. RESULTS: User satisfaction was associated with the variables of access (p < 0.001), infrastructure (p < 0.001) and quality of services (p < 0.001) in PHC. The proximity of the service, attention to spontaneous demand, listening and the respect of professionals to the singularities of the patient, as well as the problem-solving capacity of the services, without the need for referrals to others and the good infrastructure, were related to user satisfaction. CONCLUSION: To ensure the improvement of the quality of services offered in PHC in Brazil, the aspects of user satisfaction identified in this study should be considered in the organization and management of services.

Abstract Introduction Brazil is one of the countries with the highest rates of alcohol-related traffic infractions, but little is known about the profile of the drivers who commit them. Identifying the characteristics of impaired drivers is essential for planning preventive actions. Objective To compare drug use and driving behavior profiles of drivers with and without alcohol-related infractions. Methods 178 drivers stopped at routine roadblocks were assessed by traffic agents who conducted standard roadblock procedures (document verification; request of a breathalyzer test [BT]). Drug use and driving behavior data were collected through semi-structured interviews. Subjects were divided into three groups: drivers who refused the BT (RDs, n = 72), drivers who tested positive on the BT (PDs, n = 34), and drivers who had committed other infractions (ODs, n = 72). Results The proportion of alcohol use in the last year was higher among RDs (100%) than in the PD and OD groups (97.1% and 72.2% respectively, p < 0.001). Lifetime prevalence of cannabis and cocaine use for the overall sample was 44.3% and 18.2%, respectively. Fewer individuals in the OD group (31.5%) reported having been stopped at roadblocks in the previous year compared to the PDs (55.9%) and RDs (48.6%, p = 0.03). However, a higher proportion of RDs reported drunk driving in the same period (87.5%; PD 69.7%; OD 26.9%; p < 0.001). Conclusion Essential differences among groups were observed. RDs had a higher proportion of alcohol use and drunk driving in the previous year; drivers who fit into this particular group may be unresponsive or less responsive to social deterrence and enforcement actions.

Abstract Introduction The dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has a key role in drug addiction susceptibility. In addition to the well-known relationship between cortisol and the HPA axis, other molecules are involved with stress response and could modify the HPA activation, such as the neuropeptide Y (NPY), which has anxiolytic proprieties. There are few studies evaluating the effect of NPY levels on addiction, especially in crack cocaine dependence. Objective To evaluate NPY in crack users during early withdrawal to determine its relationship with drug use and cortisol levels. Methods We analyzed 25 male inpatient crack users. Serum NPY levels were measured at admission and discharge (mean of 24 days). Morning salivary cortisol was measured at admission. Results Serum NPY levels at admission and discharge were very similar. Lower NPY levels at discharge were associated with higher lifetime crack use. Also, a negative correlation was found between morning cortisol and delta NPY (NPY discharge – NPY admission). Conclusion These preliminary findings indicate that crack use influences the modulation of NPY levels and modifies stress response. The NPY pathway may play an important role in the pathophysiology of crack addiction, and the anxiolytic effect of NPY may be impaired in crack users. Future studies should consider NPY as a measurable indicator of the biological state in addiction.

Abstract Introduction Drug-related crimes, especially drug trafficking, account for a large part of incarcerations not only in Brazil, but also worldwide. It is not clear whether the change in the drug law has contributed to the increase in the number of drug trafficking prisoners. Few studies have investigated gender differences and the growth of drug trafficking offenses in the Brazilian southern state of Rio Grande do Sul. Objective To investigate the growth of the prison population in the state of Rio Grande do Sul, emphasizing incarcerations for drug trafficking and gender differences. Method This was an ecological study using secondary data collected from official databases of the Brazilian National Penitentiary Department (Departamento Penitenciário [DEPEN]), affiliated with the Brazilian Ministry of Justice. Results Between 2006 and 2015, incarcerations increased by 27% (25% men, 83% women). Incarcerations for drug trafficking accounted for 11% of total arrests in 2006 (11% men, 20% women) and 45% in 2015 (47% men, 91% women), corresponding to an increase of 427% (415% among men, 723% among women). Conclusions Imprisonment for drug trafficking has increased considerably, especially among women. This may be due to factors such as: increase of drug trafficking, increase in the numbers of gangs in the state, and changes in the Brazilian drug law. These results highlight an emerging challenge in public health from the perspective of human rights and gender.

Objective: To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. Methods: Cross-sectional study with 108 crack users. Anthropometric data were assessed through body mass index (BMI) and bioimpedance (BIA) measurements. A blood test to analyze hematocrit, hemoglobin, glucose, and lipid profiles was also performed. Crack use was determined through a standardized interview. Results: Based on BMI and BIA, most individuals were eutrophic (about 70%). Regarding hematological parameters, we found that hemoglobin and hematocrit levels were below normal for 32.4 and 30.6% of patients, respectively. Considering normal parameters, a large part of the sample (60.2%) had low levels of HDL cholesterol and high levels of triglycerides (38%). There were no significant correlations between drug profile and nutritional variables. Conclusion: This is a pioneering study that examines the nutritional status of crack users. Our results showed that most crack users present normal anthropometric findings and the prevalence of underweight is low. However, blood analysis showed changes and a specific type of malnutrition.

Objective: Many studies correlate characteristics of family functioning and the development of drug addiction. This study sought to evaluate and compare the family environment styles of two groups of psychoactive substance users: 1) alcohol-only users and 2) crack-cocaine users. Methods: Three hundred and sixty-four users of alcohol, crack-cocaine, and other drugs, recruited from research centers in four Brazilian capitals participated in this study. Subjects were evaluated through the Family Environment Scale and the Addiction Severity Index, 6th version (ASI-6). ASI-6 t-scores were compared by analysis of variance (ANOVA) and post-hoc tests. A final model was obtained using a logistic regression analysis. All analyses were adjusted for partner, age, and psychiatric t-score. Results: We found a significant difference between groups in the cohesion subscale (p = 0.044). The post-hoc test revealed a difference of 1.06 points (95%CI 0.11-2.01) between groups 1 (6.45±0.28) and 2 (5.38±0.20). No significant between-group differences were observed in the other subscales. However, categorical analyses of variables regarding family dynamic showed that crack users more often reported that sometimes people in their family hit each other (30.4% vs. 13.2%, p = 0.007) and that people in their family frequently compared each other regarding work and/or school achievement (57.2% vs. 42.6%, p = 0.041). Conclusion: These results suggest that families of crack-cocaine users are less cohesive than families of alcohol users. This type of family environment may affect treatment outcome, and should thus be adequately approached.
