Socioeconomic disparities associated with symptomatic Zika virus infections in pregnancy and congenital microcephaly: A spatiotemporal analysis from Goiânia, Brazil (2016 to 2020).

The Zika virus (ZIKV) epidemic, which was followed by an unprecedented outbreak of congenital microcephaly, emerged in Brazil unevenly, with apparent pockets of susceptibility. The present study aimed to detect high-risk areas for ZIKV infection and microcephaly in Goiania, a large city of 1.5 million inhabitants in Central-West Brazil. Using geocoded surveillance data from the Brazilian Information System for Notifiable Diseases (SINAN) and from the Public Health Event Registry (RESP-microcefalia), we analyzed the spatiotemporal distribution and socioeconomic indicators of laboratory confirmed (RT-PCR and/or anti-ZIKV IgM ELISA) symptomatic ZIKV infections among pregnant women and clinically confirmed microcephaly in neonates, from 2016 to 2020. We investigated temporal patterns by estimating the risk of symptomatic maternal ZIKV infections and microcephaly per 1000 live births per month. We examined the spatial distribution of maternal ZIKV infections and microcephaly cases across the 63 subdistricts of Goiania by manually plotting the geographical coordinates. We used spatial scan statistics estimated by discrete Poisson models to detect high clusters of maternal ZIKV infection and microcephaly and compared the distributions by socioeconomic indicators measured at the subdistrict level. In total, 382 lab-confirmed cases of maternal ZIKV infections, and 31 cases of microcephaly were registered in the city of Goiania. More than 90% of maternal cases were reported between 2016 and 2017. The highest incidence of ZIKV cases among pregnant women occurred between February and April 2016. A similar pattern was observed in the following year, although with a lower number of cases, indicating seasonality for ZIKV infection, during the local rainy season. Most congenital microcephaly cases occurred with a time-lag of 6 to 7 months after the peak of maternal ZIKV infection. The highest estimated incidence of maternal ZIKV infections and microcephaly were 39.3 and 2.5 cases per 1000 livebirths, respectively. Districts with better socioeconomic indicators and with higher proportions of self-identified white inhabitants were associated with lower risks of maternal ZIKV infection. Overall, the findings indicate heterogeneity in the spatiotemporal patterns of maternal ZIKV infections and microcephaly, which were correlated with seasonality and included a high-risk geographic cluster. Our findings identified geographically and socio-economically underprivileged groups that would benefit from targeted interventions to reduce exposure to vector-borne infections.

Motivação para primeira experiência do uso de drogas e recaídas de pessoas em tratamento / Motivation for first-time drug use and relapses of people in treatment

O objetivo deste estudo foi investigar a motivação para primeira experiência no uso de drogas e recaídas após abstinência por pessoas com dependência química induzida pelo crack. Estudo descritivo, de abordagem mista. Foram realizadas 600 entrevistas com a utilização de questionário estruturado, na etapa quantitativa, e oito grupos focais, na etapa qualitativa, com total de 39 participantes. Para análise de dados utilizou-se o software SPSS e o método de interpretação de sentidos. A curiosidade motivou a iniciação do uso de drogas, assim como a pressão dos amigos e problemas familiares. Já a dificuldade de ficar sem a droga, vontade de sentir o efeito novamente, pressão de amigos, problemas familiares, decepção pela desconfiança dos familiares e o uso de drogas na própria instituição de tratamento foram relatados como motivadores de recaída. Os dados em ambas as metodologias foram convergentes e ratificaram os resultados obtidos.

The aim of this study was to investigate the motivation for first-time drug use and relapses after abstinence of people with chemical dependency to crack cocaine. A descriptive study, with a mixed approach. In the quantitative phase, six hundred interviews were conducted using a structured questionnaire. In the qualitative phase, eight focus groups were created, with 39 total participants. SPSS software and the sense interpretation method were used to analyze the data. Curiosity, as well as peer pressure and family problems, motivated the initiation of drug use. Difficulty to live without the drug, desire to feel its effect again, peer pressure, family problems, disappointment in lack of trust of family members, and drug use at the rehabilitation institution were reported as relapse motivators. The data in both methodologies were convergent and confirmed the obtained results.

HIV-1 infection among crack cocaine users in a region far from the epicenter of the HIV epidemic in Brazil: Prevalence and molecular characteristics.

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.

Viral hepatitis in female sex workers using the Respondent-Driven Sampling.

OBJECTIVE: To estimate the prevalence of hepatitis B virus and C virus infections and their genotypes and analyze the risk factors for the markers of exposure to hepatitis B virus in female sex workers in a region of intense sex trade. METHODS: This is a cross-sectional study performed with four hundred and two female sex workers in Goiânia, Brazil. Data have been collected using the Respondent-Driven Sampling. The women have been interviewed and tested for markers of hepatitis B and C viruses. Positive samples have been genotyped. The data have been analyzed using the Respondent-Driven Sampling Analysis Tool, version 5.3, and Stata 11.0. RESULTS: The adjusted prevalence for hepatitis B virus and C virus were 17.1% (95%CI 11.6-23.4) and 0.7% (95%CI 0.1-1.5), respectively. Only 28% (95%CI 21.1-36.4) of the participants had serological evidence of vaccination against hepatitis B virus. Being older (> 40 years), being single, having a history of blood transfusion and use of cocaine, and ignoring the symptoms of sexually transmitted infections were associated with positivity for hepatitis B virus (p < 0.05). We have detected the subgenotype A1 of hepatitis B virus (n = 3) and the subtypes of hepatitis C virus 1a (n = 3) and 1b (n = 1). CONCLUSIONS: We can observe a low prevalence of infection of hepatitis B and C viruses in the studied population. However, the findings of the analysis of the risk factors show the need for more investment in prevention programs for sexual and drug-related behavior, as well as more efforts to vaccinate this population against hepatitis B. The genotypes of the hepatitis B virus and C virus identified are consistent with those circulating in Brazil.

Outreach hepatitis B vaccination of female sex workers in central-west Brazil: immunization status, compliance, and immune response.

OBJECTIVES: To evaluate the hepatitis B immunization status of female sex workers (FSWs) in Central-West Brazil and to evaluate their compliance with and immune response to hepatitis B vaccination delivered using outreach strategies. METHODS: A total of 721 FSWs recruited in 2 large cities in Central-West Brazil were interviewed and screened for the presence of hepatitis B virus (HBV) markers. Hepatitis B vaccine was offered to all women susceptible to HBV, using outreach strategies. The immune response of FSWs who received a full course of vaccine was assessed following the final vaccine dose. RESULTS: We found that 27.6% of FSWs, the majority of whom were aged 18 to 25 years, had serological evidence of previous hepatitis B vaccination. A total of 434 FSWs were eligible for vaccination, 389 (89.6%) of whom accepted the first hepatitis B vaccine dose. Of those, 64% received a second dose and 37.5% received all three doses. Through the outreach strategy, there was a 52.2% increase in the number of women who received the second dose and a 67% increase in the number who received the third dose. Of the 146 women who received a full course of vaccine, 105 accepted testing for quantitative anti-HBs (hepatitis B surface antibody) following the final vaccine dose, and 92.4% of those tested had developed protective levels of anti-HBs. Lower education level, workplace, and length of prostitution were predictors of full-vaccine acceptance. CONCLUSIONS: The present findings illustrate the benefits of using outreach strategies to overcome the difficulties of vaccinating hard-to-reach populations such as FSWs.

Vulnerability to sexually transmitted infections in women who sell sex on the route of prostitution and sex tourism in central Brazil.

OBJECTIVE: to investigate knowledge on sexually transmitted diseases (STDs), STD-related risk behaviors, and signs/symptoms of STDs among female sex workers (FSWs). METHODS: a cross-sectional study was conducted with a probabilistic sample comprising 395 women recruited using a respondent-driven sampling method between 2009 and 2010. The data were collected during face-to-face interviews. RESULTS: most of the participants were young adults, had a low educational level, and had poor knowledge on the transmission paths of the human immunodeficiency virus (HIV). Over one-third of the participants were not able to describe the signs/symptoms of STDs. The prevalence rates of vaginal discharge and wounds/ulcers were 49.0% and 8.6%, respectively, but 41.7% of the women had not sought treatment. CONCLUSION: the results indicate the need for public health policies focusing on the control and prevention of STDs in this population, especially for the FSWs who are active in an important prostitution and sex tourism route in central Brazil.

[Risk behaviors for sexually transmitted diseases among truck drivers in Brazil]. / Comportamentos de risco para doenças sexualmente transmissíveis em caminhoneiros no Brasil.

OBJECTIVE: To evaluate the frequency of sexually transmitted diseases (STD) and associated risk factors based on self-reporting by long-haul truck drivers in Brazil. METHOD: From October 2005-October 2006, 641 long-haul truck drivers that travel federal highway BR-153, traversing the country from south to north, were interviewed. A structured interview was used to collect sociodemographic data. The truck drivers also completed a self-administered questionnaire on risk behaviors and STD history. The data were adjusted and analyzed using logistic regression. RESULTS: Of 641 drivers interviewed, 620 (96.7%) provided answers on STD history. Of these, 35.6% (95% confidence interval (CI) = 31.9-39.6) reported past or current STD. Being 30 years of age or older was statistically associated with having a history of STD. In addition, truck drivers who reported using amphetamines (odds ratio (OR) = 1.7; 95%CI = 1.1-2.6), having been incarcerated (OR = 2.2; 95%CI = 1.2-4.2), and sexual relations with sex professionals (OR = 1.9; 95%CI = 1.3-2.8) had increased odds for having a history of STD. CONCLUSION: These results confirm that Brazilian truck drivers are highly vulnerable to STD and show the importance of prevention programs targeting this specific group, one that is constantly on the move and may efficiently disseminate STD.

Comportamentos de risco para doenças sexualmente transmissíveis em caminhoneiros no Brasil / Risk behaviors for sexually transmitted diseases among truck drivers in Brazil

OBJETIVO: Avaliar a freqüência de doenças sexualmente transmissíveis (DST) e os fatores de risco a elas associados conforme auto-relato em caminhoneiros de rota longa no Brasil. MÉTODO: De outubro de 2005 a outubro de 2006, foram entrevistados 641 caminhoneiros de rota longa que circulam na BR-153, uma rodovia federal que atravessa o Brasil de sul a norte. Um roteiro estruturado foi usado para a coleta de dados sociodemográficos. Os caminhoneiros responderam ainda a um questionário auto-aplicável sobre comportamentos de risco e antecedentes de DST. Os dados foram ajustados e analisados por regressão logística. RESULTADOS: Dos 641 entrevistados, 620 (96,7 por cento) responderam sobre antecedentes de DST. Desses, 35,6 por cento (IC95 por cento: 31,9 a 39,6) referiram história presente ou passada de DST. A idade superior a 30 anos foi estatisticamente associada ao relato de DST. Ainda, os caminhoneiros que relataram o uso de anfetaminas ("rebite") (razão de chances, OR: 1,7; IC95 por cento: 1,1 a 2,6), antecedentes prisionais (OR: 2,2; IC95 por cento: 1,2 a 4,2) e relacionamento sexual com profissionais do sexo (OR: 1,9; IC95 por cento: 1,3 a 2,8) apresentaram maior chance de relato de DST. CONCLUSÃO: Os resultados deste estudo ratificam a elevada vulnerabilidade dos caminhoneiros brasileiros às DST e evidenciam a importância de programas específicos de prevenção de doenças e promoção da saúde para esse grupo-alvo, que vive em constante deslocamento, sendo eficaz em disseminar as DST.
