Besides the broad spectrum of health impairment, hepatitis A, B, and C viruses also present different transmission forms, whether parenteral, sexual, vertical, or fecal-oral. Among the strategies suggested for the control of viral hepatitis, in addition to behavioral measures, are expanded diagnosis, early vaccination against hepatitis A and hepatitis B viruses, and access to available therapeutic resources. Considering vertical transmission of the hepatitis B and hepatitis C viruses, screening for pregnant women with chronic hepatitis B and C is an essential perinatal health strategy, indicating with precision those who can benefit from the prophylactic interventions.

RESUMO Introdução: As infecções sexualmente transmissíveis (ISTs) ainda são um importante problema de saúde pública, e a vigilância é essencial para sua prevenção e seu controle. Objetivo: Avaliar a prevalência das ISTs em uma unidade de referência ginecológica no Rio de Janeiro, Brasil. Materiais e métodos: Trata-se de um estudo transversal realizado entre agosto de 2016 e junho de 2017. Foram coletados sangue total e células cervicais de 62 mulheres e realizados testes para detecção de papiloma vírus humano (HPV), vírus da imunodeficiência humana (HIV), sífilis, clamídia, gonorreia e vírus do herpes simples 1 e 2 (HSV-1/2). As lesões cervicais foram diagnosticadas por citopatologia, e em algumas pacientes, por colposcopia (79%). Outras ISTs foram avaliadas durante o exame clínico. Resultados: Foram encontradas lesões cervicais pelo exame citopatológico em 46,8% das pacientes; aquelas com história de quatro parceiros sexuais tiveram mais risco de desenvolvê-las. Houve concordância moderada entre os resultados da citopatologia e colposcopia (Kappa = 0,69). A prevalência de HSV (96,7%), sífilis (6,4%) e HIV (3,2%) foi maior que a descrita na literatura, enquanto a prevalência de clamídia (6,4%) e gonorreia (1,6%) foi similar. O HPV foi detectado em 53,2% das mulheres, sendo 32,3% delas infectadas pelo HPV 16. No contexto das coinfecções, 38 mulheres (61,3%) tinham mais de uma IST. Conclusão: Visto que a maioria das mulheres analisadas era acometida por mais de uma IST, nossos resultados sugerem que uma triagem rotineira dessas infecções nas unidades de saúde poderia auxiliar na detecção precoce, bem como no tratamento e na prevenção. Essas medidas também impactariam no controle do câncer cervical das pacientes.

ABSTRACT Introduction: Sexually transmitted infections (STI) remain a major public health problem and surveillance is crucial for prevention and control strategies. Objective: Our aim was to assess the prevalence of STI in a reference center for gynecology in Rio de Janeiro, Brazil. Materials and methods: It is a cross-sectional study conducted between August 2016 and June 2017. Whole blood and cervical cells were collected from 62 women and tested for human papillomavirus (HPV), human immunodeficiency virus (HIV), syphilis, chlamydia, gonorrhea and herpes simples virus 1 and 2 (HSV-1/2). Cervical lesions were diagnosed by cytopathology and in some patients by colposcopy (79%). Other STI were evaluated during clinical examination. Results: Cervical lesions were detected by cytopathology examinations in 46.8% of patients; those with a history of four sexual partners were at higher risk of developing them. There was moderate agreement between the cytopathology e colposcopy results (Kappa = 0.69). The prevalence of HSV (96.7%), syphilis (6.4%) and HIV (3.2%) were higher than that described in the literature, while the prevalence of chlamydia (6.4%) and gonorrhea (1.6%) were similar. HPV was detected in 53.2% of women, 32.3% of which were infected by HPV 16. In the context of co-infections, 38 women (61.3%) presented more than one STI. Conclusion: Since most of the women analyzed were affected by more than one STI, our results suggest that routine screening for these infections at health centers would help in early detection, treatment and prevention of these infections. These measures would also impact on patients’ cervical cancer control.

Abstract The human C-C chemokine receptor type-5 (CCR5) is the major transmembrane co-receptor that mediates HIV-1 entry into target CD4+ cells. Gene therapy to knock-out the CCR5 gene has shown encouraging results in providing a functional cure for HIV-1 infection. In gene therapy strategies, the initial region of the CCR5 gene is a hotspot for producing functional gene knock-out. Such target gene editing can be done using programmable endonucleases such as transcription activator-like effector nucleases (TALEN) or clustered regularly interspaced short palindromic repeats (CRISPR-Cas9). These two gene editing approaches are the most modern and effective tools for precise gene modification. However, little is known of potential differences in the efficiencies of TALEN and CRISPR-Cas9 for editing the beginning of the CCR5 gene. To examine which of these two methods is best for gene therapy, we compared the patterns and amount of editing at the beginning of the CCR5 gene using TALEN and CRISPR-Cas9 followed by DNA sequencing. This comparison revealed that CRISPR-Cas9 mediated the sorting of cells that contained 4.8 times more gene editing than TALEN+ transfected cells.

ABSTRACT. Most fishing management systems in the world have long assessed and managed single-stocks over very large areas. The increasing use of the oceans and the problems faced by many fisheries have increased the trend to focus on spatial-based fisheries management. Most of the Brazilian industrial fisheries concentrate in the so-called "southeastern-south region" (SE/S), a large jurisdictional area exceeding 1600 km of latitudinal extent, along which industrial demersal fishing vessels operate quite unrestrictedly, resulting in large overlapping in their catch composition and fishing areas. Despite being essentially multi-specific, management of these fisheries is focused on a few target-species, with poor results in terms of sustainability. This paper aimed at identifying possible future spatial fishing management units for the region, based on the distribution of demersal stocks, depth, bottom characteristics and fishing dynamics from double-rig, pair and stern trawlers, bottom gillneters, bottom longliners and octopus potters which were landed in Santa Catarina harbors (southern Brazil) between 2010 and 2012. Based on these data and information from existing literature, six potential spatial units were proposed at coastal (<30 m depth), shelf (southeastern and southern sectors) (30 to 100 m), shelf break (100 to 250 m) and slope areas (>250 m). This new scheme represents a step forward in designing a final spatial management model for the SE/S industrial fisheries, improving a previous model published in the early 2000' s and conforming, in general, to the three main subdivisions recognized for the South Brazil Large Marine Ecosystem.

RESUMEN. En el mundo la mayoría de los sistemas de manejo de pesquerías han evaluado y manejado stocks únicos en extensas áreas. El aumento del uso de los océanos y los problemas enfrentados por muchas pesquerías han generado un enfoque creciente de atención en el manejo pesquero basado en áreas. La mayor parte de las pesquerías industriales brasileñas se concentra en la llamada "región sureste y sur" (SE/S), una gran área jurisdiccional que excede 1600 km de extensión latitudinal, donde los buques pesqueros involucrados en las pesquerías demersales industriales operan casi sin restricción, resultando en una gran superposición en la composición de capturas y áreas de pesca. Al ser éstas esencialmente multi-específicas, el manejo de estas pesquerías se basa en un grupo pequeño de especies objetivo con resultados pobres en términos de sustentabilidad. El artículo busca identificar posibles unidades de manejo pesquero espacial para la región, sobre la base de la distribución de los stocks demersales, profundidad y tipos de fondo, así como también en la dinámica de las flotas de arrastre dobles, arrastre simple, arrastre por parejas, enmalle de fondo, palangre de fondo y trampas para pulpo, las que desembarcaron sus capturas en los puertos de Santa Catarina (sur de Brasil) entre 2010 y 2012. Basado en estos datos y en información obtenida en la literatura, se propusieron seis unidades espaciales de manejo en la zona costera (<30 m de profundidad), plataforma continental (sectores sur y sureste, 100-250 m) y talud continental (>250 m). Este nuevo esquema representa un avance en el desarrollo de un modelo de manejo espacial para las pesquerías industriales del SE/S, mejorando un modelo anterior publicado a inicios del 2000 y se ajusta en general, a las tres principales subdivisiones reconocidas para el Gran Ecosistema Marino del Sur de Brasil.
