Understanding the clinical spectrum of complicated Plasmodium vivax malaria: a systematic review on the contributions of the Brazilian literature

The resurgence of the malaria eradication agenda and the increasing number of severe manifestation reports has contributed to a renewed interested in the Plasmodium vivax infection. It is the most geographically widespread parasite causing human malaria, with around 2.85 billion people living under risk of infection. The Brazilian Amazon region reports more than 50% of the malaria cases in Latin America and since 1990 there is a marked predominance of this species, responsible for 85% of cases in 2009. However, only a few complicated cases of P. vivax have been reported from this region. A systematic review of the Brazilian indexed and non-indexed literature on complicated cases of vivax malaria was performed including published articles, masters' dissertations, doctoral theses and national congresses' abstracts. The following information was retrieved: patient characteristics (demographic, presence of co-morbidities and, whenever possible, associated genetic disorders); description of each major clinical manifestation. As a result, 27 articles, 28 abstracts from scientific events' annals and 13 theses/dissertations were found, only after 1987. Most of the reported information was described in small case series and case reports of patients from all the Amazonian states, and also in travellers from Brazilian non-endemic areas. The more relevant clinical complications were anaemia, thrombocytopaenia, jaundice and acute respiratory distress syndrome, present in all age groups, in addition to other more rare clinical pictures. Complications in pregnant women were also reported. Acute and chronic co-morbidities were frequent, however death was occasional. Clinical atypical cases of malaria are more frequent than published in the indexed literature, probably due to a publication bias. In the Brazilian Amazon (considered to be a low to moderate intensity area of transmission), clinical data are in accordance with the recent findings of severity described in diverse P. vivax endemic areas (especially anaemia in Southeast Asia), however in this region both children and adults are affected. Finally, gaps of knowledge and areas for future research are opportunely pointed out

Homens e violência conjugal: uma análise de estudos brasileiros Men and conjugal violence: an analysis of Brazilian studies

O estudo analisou qualitativamente 54 textos brasileiros sobre homens e violência conjugal, relacionados a atividades de pesquisa ou de intervenção. Primeiramente caracterizou-se o material quanto aos temas abordados, ao foco principal e ao tipo de texto. A seguir fizeram-se sínteses e análises das principais considerações dos textos a partir dos eixos temáticos encontrados: diferentes inteligibilidades da problemática, magnitude da violência conjugal, sentidos de homens relacionados à violência e intervenções e/ou políticas junto a homens agressores. A análise teve como parâmetro o ramo de discussões nacionais e internacionais que se esforça por ultrapassar a polêmica em torno da definição do problema como "violência de gênero" ou "violência conjugal", cunhando sobretudo o pressuposto de que existem diversos estilos de conjugalidade violenta. Concluiu-se que a maior unanimidade dos estudos é pensar a problemática como questão relacional de gênero. Defendeu-se, por fim, a ideia de que a escolha da melhor abordagem articuladora entre os polos da polêmica ainda demanda mais investigações, com metodologias qualitativas junto a atores de diferentes camadas e grupos sociais. Quanto às intervenções, propõem-se investimentos no maior número possível de alternativas, valorizando a singularidade dos casos.<br>This study consisted of a qualitative analysis of 54 Brazilian texts about men and conjugal violence related to research or intervention activities. Initially, the material was divided up according to the topics under scrutiny, the main focus and the type of text. Analysis and synthesis of the main considerations of the texts, based on the thematic points revealed, was then carried out. This included the different approaches to the problem, the magnitude of conjugal violence, the attitudes of men vis-à-vis violence and interventions and/or policies towards male aggressors. The parameter for the analysis was the national and international debate seeking to overcome the controversy surrounding the definition of the problem as "gender violence" or conjugal violence," essentially fostering the hypothesis of various types of violent conjugal relationships. It was concluded that the unanimous outcome of the study was to view the problem as a gender relationship issue. Lastly, it was argued that the choice of the best approach between the poles of the controversy requires further investigation using qualitative methodologies together with players from different classes and social backgrounds. With respect to further intervention, it was considered necessary to examine a broad gamut of alternatives emphasizing the singular nature of the cases
