Reproductive Desire in Women Living with HIV/AIDS with Serodiscordant Partners.

OBJECTIVE: To estimate the prevalence and factors associated with reproductive desire in a sample of women living with HIV/AIDS (WLHA) with serodiscordant partners. STUDY DESIGN: Between September 2015 and August 2016, a cross-sectional study was conducted among 110 WLHA from HIV/AIDS treatment services and non-governmental organizations. An interview was conducted using a structured questionnaire to collect sociodemographic data, reproductive desire, and potential predictor variables. Poisson regression was used to analyze the factors associated with reproductive desire in the sample. RESULTS: The prevalence of reproductive desire was 32.7% (95% Confidence Interval: % CI: 24.7-42.0%). In regression analysis, we observed an association between reproductive desire and the following variables: age < 30 years; relationship time < 2 years; reproductive desire for the partner; and absence of children. CONCLUSIONS: The prevalence of reproductive desire in the investigated sample was relatively high. Young age and reproductive desire for the partner were the main associated factors.

Molecular epidemiological investigation of Mayaro virus in febrile patients from Goiania City, 2017-2018.

Mayaro virus (MAYV) has historically been associated with sylvatic transmission; however, urban outbreaks have been reported in Brazil, including cases of co-detection with dengue virus (DENV). Therefore, we performed a molecular survey to investigate MAYV circulation and cocirculation with DENV within Goiania, a major city in Central-West Brazil. Among 375 subjects with arbovirus-like symptoms, 259 were positive for DENV and 26 for MAYV. Of these, 17 were coinfected with DENV-2, suggesting co-transmission of the viruses. The most common complaints at the time of inclusion were myalgia, headache, fever, arthralgia, retro-orbital pain, and skin rash. No specific symptoms were associated with MAYV when either detected alone or co-detected with DENV, compared to that when DENV was detected alone. Most MAYV-infected subjects were women with no recent travel history to rural/sylvatic areas. Phylogenetic reconstruction indicated that the MAYV identified in this study is closely related with a lineage observed in Peru, belonging to genotype D. Our results corroborate the growing circulation of MAYV in urban environments in Brazil and reinforce the need to implement laboratory diagnosis in the Unified Health System, considering that the clinical manifestations of Mayaro fever are similar to those of other arboviruses, particularly dengue. Furthermore, most cases occurred in association with DENV-2. Further phylogenetic studies are needed to evaluate MAYV, which has not been widely examined.

Bio-behavioral survey of syphilis in homeless men in Central Brazil: a cross-sectional study.

The objective of this study was to investigate the prevalence and factors associated with syphilis in homeless men in Central Brazil. It is a cross-sectional study conducted with 481 individuals attending four therapeutic communities between October and December 2015. A structured interview was conducted to collect sociodemographic data and risk factors for syphilis. Rapid/point-of-care and VDRL tests were performed to determine exposure to syphilis and the presence of active syphilis, respectively. Poisson regression analysis was used to verify the risk factors associated with the outcomes investigated. Of the study participants, 10.2% were reactive to the rapid test, and 5.4% had active syphilis. At the multiple regression analysis, schooling (adjusted prevalence ratio - APR: 0.89; p = 0.005), history of genital ulcer (APR: 2.59; p = 0.002), STI history (APR: 1.97; p = 0.042), and sexual intercourse under drug effects (APR: 1.60; p = 0.022) were independent factors associated with lifetime syphilis. Also, history of genital ulcer (APR: 2.19; p = 0.019), STI history (APR: 1.74; p = 0.033) and number of sexual partners in the last year (APR: 1.02; p = 0.044) were associated with active syphilis. The prevalence of syphilis among homeless men was rather high, confirming the vulnerability of this group to this infection. These results emphasize the need for educational intervention, improvement of risk reduction programs, availability of diagnostic tests, especially the rapid test, and treatment.

O estudo teve como objetivo investigar a prevalência da sífilis e fatores associados em homens sem-teto no Centro-oeste do Brasil. A amostra nesse estudo transversal incluiu 481 indivíduos que frequentavam comunidades terapêuticas entre outubro e dezembro de 2015. Uma entrevista estruturada foi usada para coletar dados sociodemográficos e fatores de risco para sífilis. Foram realizados testes rápidos e VDRL para determinar a exposição à sífilis e a presença de sífilis ativa, respectivamente. A análise de regressão de Poisson foi usada para verificar os fatores de risco associados aos desfechos investigados. Entre os participantes, 10,2% foram reativos ao teste rápido e 5,4% tinham sífilis ativa. Na análise de regressão múltipla, a escolaridade (razão de prevalência ajustada - RPA: 0,89; p = 0,005), história de úlcera genital (RPA: 2,59; p = 0,002), história de DST (RPA: 1,97; p = 0,042) e relações sexuais sob o efeito de drogas (RPA: 1,60; p = 0,022) apareceram como fatores independentes associados à história pregressa de sífilis. Além disso, a história de úlcera genital (RPA: 2,19; p = 0,019), história de DST (RPA: 1,74; p = 0,033) e número de parceiros sexuais no último ano (RPA: 1,02; p = 0,044) estiveram associados à sífilis ativa. A prevalência de sífilis em homens sem-teto era bastante elevada, confirmando a vulnerabilidade desse grupo à infecção. Os achados enfatizam a necessidade de intervenções educacionais, melhoria dos programas de redução de risco, disponibilidade de testes diagnósticos (sobretudo o teste rápido) e tratamento adequado.

Reproductive desire among women living with HIV/AIDS in Central Brazil: Prevalence and associated factors.

BACKGROUND: The purpose of this study was to estimate the prevalence and examine the factors associated with reproductive desire among women living with HIV/AIDS (WLWHA) in Central Brazil. METHODS: A cross-sectional study involving 274 WLWHA, aged 18 to 49 years, was conducted with the support of treatment services and non-governmental organizations that assist people living with HIV/AIDS. Data regarding sociodemographic characteristics, substance use, sexual behavior, and reproductive variables were collected through interviews. Poisson regression with robust variance was used to analyze the factors associated with reproductive desire. RESULTS: The prevalence of reproductive desire was 25.9% (95.0% confidence interval [CI]: 21.1-31.4%). This outcome was associated with age < 30 years (adjusted prevalence ratio [APR]: 2.93; p < 0.001), black skin color or race (APR: 2.28; p = 0.017), partner's reproductive desire (APR: 7.55; p < 0.001), absence of children (APR: 2.13; p = 0.003), history of abortion (APR: 1.65; p = 0.045) and undetectable viral load at the time of data collection (APR: 1.92; p = 0.043). CONCLUSION: The prevalence of reproductive desire among WLWHA was relatively high. It is necessary to include fertility issues as part of assistance and counseling for women in referral services to support them with their feelings, goals, and needs regarding reproductive choices.

Exposure to hepatitis C virus in homeless men in Central Brazil: a cross-sectional study.

BACKGROUND: Homeless men are highly vulnerable to acquisition of the hepatitis C virus (HCV) compared to the general population. In Brazil, a country of continental dimensions, the extent of HCV infection in this population remains unknown. The objective of this study is to investigate the epidemiological profile of exposure to HCV in homeless men in Central Brazil. METHODS: A Cross-sectional study was conducted in 481 men aged over 18 years attending therapeutic communities specialized in the recovery and reintegration of homeless people. Participants were tested for anti-HCV markers using rapid tests. Poisson regression analysis was used to verify the risk factors associated with exposure to HCV. RESULTS: The prevalence of HCV exposure was 2.5% (95.0% CI: 1.4 to 4.3%) and was associated with age, absence of family life, injection drug use, number of sexual partners, and history of sexually transmitted infections (STI). Participants reported multiple risk behaviors, such as alcohol (78.9%), cocaine (37.1%) and/or crack use (53.1%), and inconsistent condom use (82.6%). Injection drug use was reported by 8.7% of participants. CONCLUSIONS: The prevalence of HCV infection among homeless men was relatively high. Several risk behaviors were commonly reported, which shows the high vulnerability of this population. These findings emphasize the need for the development of specific strategies to reduce the risk of HCV among homeless men.

Epidemiology of hepatitis B virus infection in first-time blood donors in the southwestern region of Goiás, central Brazil

INTRODUCTION: Little is known about the epidemiology of hepatitis B virus (HBV) infection in populations from inner cities, especially in Central Brazil. Thus the objective of this study was to estimate the prevalence of HBV infection, and to analyze the factors associated with HBV infection, in a population of first-time blood donors in the southwestern region of Goiás, Central Brazil. METHODS: A total of 984 individuals were interviewed and gave blood samples to detect serological markers of HBV (HBsAg, anti-HBs, and anti-HBc) by enzyme linked immunosorbent assays. RESULTS: An overall prevalence of 6.9 percent was found for HBV, with constituent prevalence rates of 3.6 percent and 11.6 percent, in subjects classified as fit and unfit to donate blood according the epidemiological screening, respectively. Only three individuals were positive for anti-HBs alone, suggesting previous vaccination against HBV. The variables of prior blood transfusion (OR = 2.3), tattoo/piercing (OR = 2.1), illicit drug use (OR = 2.3), sex with a partner with hepatitis (OR = 14.7), and history of sexually transmitted diseases (OR = 2.9) were independently associated with HBV-positivity. These data suggested a low endemicity of hepatitis B in the studied population. CONCLUSION: The findings of low hepatitis B immunization coverage and the association of hepatitis B with risky behavior highlight that there is a need to intensify hepatitis B prevention programs in the southwest region of Goiás.

[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.
