ABSTRACT OBJECTIVE This study aims to assess the degree of adequacy of prenatal care (PNC) in the state of Rio Grande do Sul (RS) and in its 7 macro-regions considering the time of PNC initiation and the number of appointments attended. It also aims to verify the mode of delivery prevalence and the factors associated with PNC adequacy by mode of delivery. METHODS Sub analysis from a cross-sectional study conducted among 13,432 childbearing women aged 15–49 years assisted in 66 maternity hospitals of the Unified Health System (SUS) and private associated facilities from September 2017 to October 2019. A standardized form was used to collect sociodemographic data, and information about PNC and delivery from the childbearing women’s prenatal cards, hospital records, and medical reports. RESULTS The PNC coverage was (98.4%), but only 57.5% of the participants had an adequate PNC defined as the one initiated until the 12th gestational week, with attendance of at least 6 appointments. The cesarean rate was 57.2%. Among women who performed vaginal delivery, multivariate analysis showed that for each 1-year increase in the age of the parturient, the chance of having an adequate PNC increased by 5%. White parturients with higher education and fewer deliveries residing in the macro-region of Valleys were more likely to have an adequate PNC when compared with non-white parturients, who were illiterate and/or had incomplete elementary school, with 3 or more deliveries and who resided in other macro-regions. During pregnancy, 96.0% of the women performed at least one anti-HIV test, 55.8% a rapid test for syphilis, and 75.0% a Venereal Disease Research Laboratory test (VDRL). CONCLUSIONS Despite the almost universal PNC coverage in RS, the PNC offered by the SUS was adequate for just half of the population, therefore public health policies targeted at women receiving care in this setting shall be revisited.

ABSTRACT Background: Women living with human immunodeficiency virus (HIV) (WLWH) are more likely to be infected with the oncogenic human papillomavirus (HPV). We assessed the prevalence of high-risk (HR) (16/18/31/33/35/39/45/51/52/56/58/59/68/73/82), probable high-risk (pHR) (26/53/66), and low-risk (LR) (6/11/40/42/43/44/54/61/70) HPV types and their associated risk factors. Methods: This cross-sectional study of WLWH aged 18-64 years included one laboratory and eight HIV-specialty healthcare facilities in the pilot network. Descriptive statistics were used to assess sociodemographic and behavioral characteristics. Adjusted analyses were conducted to evaluate risk factors associated with HR and/or pHR HPV infection in WLWH. Results: From May/2021 to May/2022, 1,914 (92.5%) WLWH participated in the pilot study and had valid HPV-DNA results of self-collected vaginal samples. The median age of the participants was 45 years, 60.1% had ≥ 9 years of schooling, 80.5% were ≤ 18 years at first sexual intercourse, and 51.7% had > 4 sexual partners throughout life. The prevalence of any HPV type, HR HPV, pHR HPV, and LR HPV was 65.8%, 49.6%, 16.7%, and 40.0%, respectively. Age was inversely associated with pHR and/or HR-HPV (p < 0.001), and education level was inversely associated with HR-HPV (p = 0.003) types. Any HR or pHR was associated with being single (p = 0.029) and exchanging sex for drugs (p = 0.037). Conclusions: The prevalence of HPV, especially HR HPV, among WLWH is high in Brazil, highlighting the need for HPV screening in this population. Self-collection of vaginal samples is an important strategy for increasing testing access.

ABSTRACT Background: Gonorrhea is not a notifiable disease in Brazil, and the national health information system does not collect data on reported cases or infection prevalence. Methods: We compiled published data on gonorrhea prevalence in Brazil from cross-sectional surveys and clinical trials between 2000 and 2020. The study entry criteria included a sample size of 50 or more, and Neisseria gonorrhoeae infection detected in urine, urethral, anal, or cervicovaginal specimens using either Nucleic Acid Amplification Test or culture. Gonorrhea prevalence trends between 2000 and 2020 were generated using Spectrum-STI, a statistical trend-fitting model. Results: Forty-five studies with 59 gonorrhea prevalence data points were identified. Fifty data points were for women and represented 21,815 individuals, eight for men encompassing a total of 4,587 individuals, and one for transgender people comprising 345 individuals. The Spectrum-STI estimate for the prevalence of urogenital infection with gonorrhea in women 15-49 in 2020 was 0.63% (95% confidence interval (CI): 0.13-2.23) and was lower than the 1.05% estimated value for 2000 (95% CI: 0.36-2.79). The corresponding figures for men were 0.70% (95% CI: 0.16-2.44) and 1.14% (95% CI: 0.34-3.15). Anal prevalence estimates could not be generated because of insufficient data (three data points). Conclusions: These results suggest that the overall prevalence of genitourinary gonococcal infections in Brazil is less than 1%. Data on gonorrhea prevalence in men and in populations at increased STI vulnerability are limited.

Resumo: A profilaxia pré-exposição ao HIV (PrEP) tem sido considerada uma estratégia fundamental para o controle da epidemia de HIV/aids, e desde 2018 tem sido objeto de estudo de implementação (Estudo ImPrEP Stakeholders), realizado no Brasil, no México e no Peru. Um componente qualitativo desse estudo foi desenvolvido com o objetivo de identificar os contextos sociais e estruturais que envolvem e organizam a oferta de serviços de PrEP no Brasil, as subjetividades dos atores envolvidos e as diferentes percepções que podem impactar a efetivação dessa estratégia. O presente artigo teve como foco de análise o acesso das populações vulneráveis aos serviços de PrEP, na perspectiva de gestores, profissionais de saúde, lideranças ou ativistas e usuários de PrEP. É um estudo qualitativo com o uso de metodologia compreensiva, realizado em seis capitais brasileiras, em que foram entrevistados 71 atores-chave no período de novembro de 2018 a maio de 2019. A análise foi pautada pelos modelos analíticos sobre acesso propostos por Giovanella & Fleury, McIntyre et al. e Penchansky & Thomas. Os resultados são apresentados com base em três eixos: “percepções sobre prevenção combinada e PrEP”; “disponibilidade e adequação: perfil e estrutura dos serviços no contexto do ImPrEP”; e “aceitabilidade: atitudes e práticas dos profissionais de saúde e usuários”.

Abstract: HIV preexposure prophylaxis (PrEP) has been considered a fundamental strategy for controlling the HIV/AIDS epidemic, and since 2018 it has been the object of an implementation study (ImPrEP Stakeholders Study), conducted in Brazil, México, and Peru. A qualitative component of this study was developed with the objective of identifying the social and structural contexts that involve and organize the supply of PrEP services in Brazil, the stakeholders’ subjectivities, and the different perceptions that can impact the strategy’s implementation. The current article’s focus was to analyze access by vulnerable populations to PrEP services from the perspective of managers, health professionals, leaders or activists, and users of PrEP. This was a qualitative study using a comprehensive methodology, conducted in six Brazilian state capitals, interviewing 71 key actors from November 2018 to May 2019. The analysis was based on access analysis models as proposed by Giovanella & Fleury, McIntyre et al. and Penchansky & Thomas. The results are presented along three lines: “perceptions of combined prevention and PrEP”, “availability and adequacy: profile and structure of services in the context of ImPrEP”, and “acceptability: attitudes and practices of health professionals and users”.

Abstract Sub-daily resolution rain gauge data (pluviographic records) should be used to define extreme rainfall intensity-frequency-duration curves. However, there is a lack of these records for many countries, which leads to the application of rainfall disaggregation models that transforms maximum daily rainfall data into sub-daily depths. The agreement between the intensity-duration-frequency curves obtained with disaggregation models and using sub-daily rainfall data is necessary to support the disaggregation method's applicability. The daily rainfall disaggregation method using disaggregation coefficients is the most used in Brazil, despite the lack of performance evaluation. The linear regression and model identity test was used to compare the intensity of rainfall obtained with different methodologies to obtain intensity-duration-frequency curves in 116 rain gauges in Minas Gerais, Brazil. There is a significant difference between the maximum rainfall intensity (im) obtained from pluviographic records and those estimated by the daily rainfall disaggregation. Nevertheless, comparing the im estimated by the daily rainfall disaggregation methods and the im obtained by sub-daily rainfall data, good precision and accuracy are observed, especially using specific disaggregation coefficients. The disaggregation IDF relationships had an underestimation tendency of im, especially in larger return periods, which can be considered less harmful since the larger return periods are associated with higher safety projects. The practical result of this paper was the possibility of a simple and effective methodology to disaggregate the daily into a sub-daily resolution rainfall.

O objetivo foi caracterizar aspectos sociodemográficos, comportamentais e clínicos entre conscritos brasileiros, segundo a prevalência de sífilis. Estudo descritivo desenvolvido valendo-se de pesquisa nacional de base populacional, realizada em 2016, com amostra probabilística de jovens conscritos de 17 a 22 anos de idade. Realizou-se autoaplicação de questionários confidenciais. As amostras de sangue total dos participantes foram coletadas para testagem de sífilis, com a utilização de testes treponêmicos e não treponêmicos. Empregaram-se técnicas de estatística descritiva para estimar as prevalências de sífilis e a distribuição de frequências entre as variáveis pesquisadas, considerando os intervalos de 95% de confiança (IC95%), após a ponderação dos dados. Do total de 37.282 participantes, 73,7% haviam iniciado a vida sexual. As prevalências de sífilis na vida e de sífilis confirmada foram de 1,6% e 1,1%, respectivamente. As seguintes variáveis populacionais apresentaram maior prevalência de sífilis: ausência de acesso à Internet no domicílio; início da atividade sexual antes dos 14 anos; categoria de exposição homens que fazem sexo com homens; práticas sexuais com mais de cinco parcerias; recebimento de presentes, drogas ou outros incentivos em troca de sexo; e história prévia de sintomatologia de infecções sexualmente transmissíveis. Observou-se o aumento de sífilis entre os jovens conscritos brasileiros, em comparação aos inquéritos anteriores. Tal incremento reforça a importância dessa população sentinela para realizar vigilância ativa, de forma a subsidiar estratégias de atenção à saúde dos jovens, incluindo cenários escolares.

The objective was to characterize sociodemographic, behavioral, and clinical aspects in young Brazilian military recruits according to prevalence of syphilis. This was a descriptive study based on a nationwide population-based survey in 2016 with a probabilistic sample of military recruits 17 to 22 years of age. A confidential self-applied questionnaire was used. Blood samples were drawn from participants for treponemal and non-treponemal syphilis tests. Descriptive statistical techniques were used to estimate syphilis prevalence rates and distribution of frequencies between the target variables, considering 95% confidence intervals (95%CI), after weighting the data. Of the total of 37,282 participants, 73.7% were sexually initiated. Prevalence rates for lifetime and confirmed syphilis were 1.6% and 1.1%, respectively. The following population variables showed higher prevalence of syphilis: lack of Internet access at home; initiation of sexual activity before 14 years of age; men who have sex with men; more than five sexual partners; having received presents, drugs, or other incentives in exchange for sex; and prior history of symptoms of sexually transmissible infections. An increase was observed in syphilis in Brazilian military recruits when compared to previous surveys. This increase emphasizes the importance of this sentinel population for performing active surveillance in order to support healthcare strategies for youth, including in the school system.
