REPORTING OF SEXUAL VIOLENCE AGAINST WOMEN IN BRAZIL

Objetivo: Apresentar o quadro de violência sexual contra a mulher no Brasil, com base nas notificações realizadas no Sistema de Informação de Agravos de Notificação (SINAN). Métodos: Trata-se de um estudo descritivo, com abordagem quantitativa, que analisou informações referentes às notificações de violência sexual contra a mulher, no período de 2009 a 2013, considerando a unidade da federação, perfil das mulheres, características da ocorrência e encaminhamentos realizados pelo setor saúde. Os dados foram analisados por meio da estatística descritiva, sendo apresentados números absolutos e relativos derivados das notificações. Resultados: No Brasil, foram registradas 21.871 notificações no período estudado. Observaram-se maiores taxas de registros no ano de 2013 e na região Norte. Predominou o ciclo de vida de 10 a 19 anos (10.806/49,4%), as raças branca (8.894/40,7%) e parda (8.535/39,0%), e a escolaridade ensino fundamental incompleto (5.444/24,9%). Os casos de violência sexual ocorreram com maior frequência na residência da mulher (13.259/60,6%), com agressor conhecido (5.649/25,8%) e sem suspeita do uso de álcool (9.249/42,3%). A maior parte do atendimento no setor saúde foi de nível ambulatorial (15.842/72,6%), e os casos evoluíram para alta (16.879/77,2%). Conclusão: As notificações cresceram progressivamente no período estudado, e a violência sexual contra a mulher no país, registrada pelo setor saúde, atingiu, principalmente, adolescentes, no ambiente doméstico e com agressor conhecido.

ADVANCES AND CHALLENGES OF BREASTFEEDING IN BRAZIL: AN INTEGRATIVE REVIEW

Objective: To analyze the panorama of breastfeeding in Brazil through an integrative literature review highlighting its advances and challenges. Methods: We carried out an integrative literature review in the SciELO and PubMed databases and in booklets published on the websites of the Ministry of Health and the International Baby Food Action Network (IFBAN) using the following Portuguese and English descriptors: aleitamento materno (breastfeeding), autoeficácia (self-efficacy), promoção da saúde (health promotion) and desmame (weaning) in the period from 2002 to 2015. Results: We identified at first 43 articles, 33 booklets, 1 thesis and 3 dissertations, including in the study 17 articles, 3 dissertations and 19 booklets due to information saturation. It was verified that breastfeeding rates have reduced significantly over time with direct implications in infant mortality rates, being associated with early weaning and the lack of promotion of maternal self-efficacy in the prenatal and postpartum. To change this situation, Brazil imposed a number of public policies aimed at breastfeeding success, which advocated to raise rates. Conclusion: Despite the advances, the Brazilian panorama of breastfeeding shows that the country remains below the recommendations of international organizations, and overcoming the obstacles to successful breastfeeding constitutes a major challenge for the Brazilian public health.

VITAMIN “A” FOOD CONSUMPTION BY PREGNANT WOMEN IN BRAZIL: A SYSTEMATIC REVIEW

Objective: To conduct a systematic review of the Vitamin “A” food consumption by pregnant women in Brazil. Methods: The review consisted of a search for articles published in the period from 1999 to 2015 in SciELO, PubMed, and LILACS databases. At the end, eight articles were selected for this review. Results: The methods used for the analysis of the intake of vitamin “A” were: food frequency questionnaire (FFQ) – considering the diet or only vitamin “A” foods and the dietary recall (24hDR). Only two articles estimated the adequacy of the Vitamin “A” food consumption by the population assessed. Some methodological limitations were quite frequent, emphasizing the lack and/or limitation of information on the sample representativeness, loss of studies, accuracy of the methods applied and the control of confounding variables. Conclusion: It is observed that there are still few studies that critically assess the Vitamin “A” food consumption by pregnant women in Brazil, and that the identification and control of possible biases of the dietary surveys can improve the reliability of the information found.

Clostridium difficile ribotypes in humans and animals in Brazil

Clostridium difficile is an emerging enteropathogen responsible for pseudomembranous colitis in humans and diarrhoea in several domestic and wild animal species. Despite its known importance, there are few studies about C. difficile polymerase chain reaction (PCR) ribotypes in Brazil and the actual knowledge is restricted to studies on human isolates. The aim of the study was therefore to compare C. difficile ribotypes isolated from humans and animals in Brazil. Seventysix C. difficile strains isolated from humans (n = 25), dogs (n = 23), piglets (n = 12), foals (n = 7), calves (n = 7), one cat, and one manned wolf were distributed into 24 different PCR ribotypes. Among toxigenic strains, PCR ribotypes 014/020 and 106 were the most common, accounting for 14 (18.4%) and eight (10.5%) samples, respectively. Fourteen different PCR ribotypes were detected among human isolates, nine of them have also been identified in at least one animal species. PCR ribotype 027 was not detected, whereas 078 were found only in foals. This data suggests a high diversity of PCR ribotypes in humans and animals in Brazil and support the discussion of C. difficile as a zoonotic pathogen.

Genetic diversity of Cryptosporidium identified in clinical samples from cities in Brazil and Argentina

The identification and characterisation of Cryptosporidium genotypes and subtypes are fundamental to the study of cryptosporidiosis epidemiology, aiding in prevention and control strategies. The objective was to determine the genetic diversity of Cryptosporidium in samples obtained from hospitals of Rio de Janeiro, Brazil, and Buenos Aires, Argentina. Samples were analysed by microscopy and TaqMan polymerase chain reaction (PCR) assays for Cryptosporidium detection, genotyped by nested-PCR-restriction fragment length polymorphism (RFLP) analysis of the 18S rRNA gene and subtyped by DNA sequencing of the gp60 gene. Among the 89 samples from Rio de Janeiro, Cryptosporidium spp were detected in 26 by microscopy/TaqMan PCR. In samples from Buenos Aires, Cryptosporidium was diagnosed in 15 patients of the 132 studied. The TaqMan PCR and the nested-PCR-RFLP detected Cryptosporidium parvum , Cryptosporidium hominis , and co-infections of both species. In Brazilian samples, the subtypes IbA10G2 and IIcA5G3 were observed. The subtypes found in Argentinean samples were IbA10G2, IaA10G1R4, IaA11G1R4, and IeA11G3T3, and mixed subtypes of Ia and IIa families were detected in the co-infections. C. hominis was the species more frequently detected, and subtype family Ib was reported in both countries. Subtype diversity was higher in Buenos Aires than in Rio de Janeiro and two new subtypes were described for the first time.

First description of Candida nivariensis in Brazil: antifungal susceptibility profile and potential virulence attributes

This study evaluated the antifungal susceptibility profile and the production of potential virulence attributes in a clinical strain of Candida nivariensis for the first time in Brazil, as identified by sequencing the internal transcribed spacer (ITS)1-5.8S-ITS2 region and D1/D2 domains of the 28S of the rDNA. For comparative purposes, tests were also performed with reference strains. All strains presented low planktonic minimal inhibitory concentrations (PMICs) to amphotericin B (AMB), caspofungin (CAS), and voriconazole. However, our strain showed elevated planktonic MICs to posaconazole (POS) and itraconazole, in addition to fluconazole resistance. Adherence to inert surfaces was conducted onto glass and polystyrene. The biofilm formation and antifungal susceptibility on biofilmgrowing cells were evaluated by crystal violet staining and a XTT reduction assay. All fungal strains were able to bind both tested surfaces and form biofilm, with a binding preference to polystyrene (p < 0.001). AMB promoted significant reductions (≈50%) in biofilm production by our C. nivariensis strain using both methodologies. This reduction was also observed for CAS and POS, but only in the XTT assay. All strains were excellent protease producers and moderate phytase producers, but lipases were not detected. This study reinforces the pathogenic potential of C. nivariensis and its possible resistance profile to the azolic drugs generally used for candidiasis management.

Respiratory syncytial virus seasonality in Brazil: implications for the immunisation policy for at-risk populations

Respiratory syncytial virus (RSV) infection is the leading cause of hospitalisation for respiratory diseases among children under 5 years old. The aim of this study was to analyse RSV seasonality in the five distinct regions of Brazil using time series analysis (wavelet and Fourier series) of the following indicators: monthly positivity of the immunofluorescence reaction for RSV identified by virologic surveillance system, and rate of hospitalisations per bronchiolitis and pneumonia due to RSV in children under 5 years old (codes CID-10 J12.1, J20.5, J21.0 and J21.9). A total of 12,501 samples with 11.6% positivity for RSV (95% confidence interval 11 - 12.2), varying between 7.1 and 21.4% in the five Brazilian regions, was analysed. A strong trend for annual cycles with a stable stationary pattern in the five regions was identified through wavelet analysis of the indicators. The timing of RSV activity by Fourier analysis was similar between the two indicators analysed and showed regional differences. This study reinforces the importance of adjusting the immunisation period for high risk population with the monoclonal antibody palivizumab taking into account regional differences in seasonality of RSV.

Leprosy in children and adolescents under 15 years old in an urban centre in Brazil

This original study describes the intra-urban distribution of cases of leprosy in residents under 15 years old in Salvador, Bahia, Brazil; the study also identifies the environment in which Mycobacterium leprae is being transmitted. The cases were distributed by operational classification, clinical forms, type of contact and the addresses were geo-referenced by neighborhood. Between 2007 and 2011, were reported 145 cases of leprosy in target population living in Salvador, corresponding to detection rates of 6.21, 6.14, 5.58, 5.41 and 6.88/100,000 inhabitants, respectively. The spatial distribution of the disease was focal. Of the 157 neighborhoods of Salvador, 44 (28.6%) notified cases of leprosy and in 22 (50%) of these were detected more than 10 cases per 100,000 inhabitants. The infectious forms were found in 40% of cases. Over 90% of cases had been living in Salvador for more than five years. Overall, 52.6% reported having had contact with another infected individual inside the household and 25% in their social circle. In Salvador, M. leprae transmission is established. The situation is a major concern, since transmission is intense at an early age, indicating that this endemic disease is expanding and contacts extend beyond individual households.

Candida duobushaemulonii: an emerging rare pathogenic yeast isolated from recurrent vulvovaginal candidiasis in Brazil

The aim of this study was to identify Candida species isolated from women diagnosed with recurrent vulvovaginal candidiasis (RVVC) and their partners; and to evaluate the fluconazole (FLZ) susceptibility of the isolates. In a period of six years, among 172 patients diagnosed with vulvovaginal candidiasis, 13 women that presented RVVC and their partners were selected for this investigation. The isolates were obtained using Chromagar Candida medium, the species identification was performed by phenotypic and molecular methods and FLZ susceptibility was evaluated by E-test. Among 26 strains we identified 14 Candida albicans , six Candida duobushaemulonii, four Candida glabrata , and two Candida tropicalis . Agreement of the isolated species occurred in 100% of the couples. FLZ low susceptibility was observed for all isolates of C. duobushaemulonii (minimal inhibitory concentration values from 8-> 64 μg/mL), two C. glabrata isolates were FLZ-resistant and all C. albicans and C. tropicalis isolates were FLZ-susceptible. This report emphasises the importance of accurate identification of the fungal agents by a reliable molecular technique in RVVC episodes besides the lower antifungal susceptibility profile of this rare pathogen C. duobushaemulonii to FLZ.
