A taxa de mortalidade infantil é considerada indicador síntese da qualidade de vida e do nível de desenvolvimento de uma população. Este artigo analisa a evolução dessas taxas no Município do Rio de Janeiro, no período de 1979 a 2004, e as causas em 2004. Trata de estudo descritivo a partir do total de óbitos infantis e nascimentos ocorridos, utilizando-se os sistemas de informação produzidos pelo Ministério da Saúde. Para avaliação, segundo causa básica de morte, usou-se a Classificação Internacional de Doenças. As taxas de mortalidade infantil por mil nascidos vivos decresceram de 37,4 em 1979 para 15,1 em 2004, sendo o componente pós-neonatal o principal responsável por este declínio. Em 2004, as principais causas de óbito neonatais foram as afecções perinatais e as malformações congênitas; entre os óbitos pós-neonatais destacaram-se as doenças infecciosas e parasitárias, as causas mal definidas e as doenças respiratórias. Embora tenha sido observada queda da taxa de mortalidade infantil, esta não teve uma redução maior, devido ao pequeno declínio do componente neonatal precoce. Observou-se que a assistência à saúde da criança, no município do Rio de Janeiro, ainda deixa a desejar no que se refere à integralidade da assistência desde o período pré-natal.

Objective: to describe operational difficulties in the implementation of deltamethrin-impregnated dog collars for the control of visceral leishmaniasis. Methods: this was a community intervention trial in the municipality of Montes Claros, MG, Brazil, comparing (i) control area -dogs without dog collars -and (ii) intervention area -use of 4% deltamethrin-impregnated collars; an initial serological survey was performed, followed by three further cycles (at 12, 18 and 24 months). Results: out of 4,388 dogs initially seronegative wearing collars, 36.9% were not found in the second cycle, 27.0% of them were lost owing to disappearance/given away/sale, and 22.6% because no one was at home; 56.1% of collars were lost in one year; while among dogs that stayed longer in the study, collar loss was lower. Conclusion: high frequencies of collar loss and no one being at home at the time of the visit are operational difficulties for the implementation of a national control program based on the strategy evaluated.

Abstract. The aim of this study was to characterize risk profiles for Leishmania infantum infection in a population living in an area endemic for visceral leishmaniasis. A cohort study was conducted between January 2004 and December 2006 with the participation of 430 individuals living in the city of Teresina, northeast Brazil, who were initially negative for the Montenegro test. Data analysis was performed using the classification and regression tree method. The cumulative incidence (CI) of Montenegro's test conversion was 35% at 18-month follow-up. Eight different risk profiles for L. infantum infection were identified. The profile with the highest risk (CI = 75%) comprised individuals with less than 4 years of education who had never lived outside Teresina. The profile with the lowest risk (CI = 5%) included highly educated subjects who had owned a dog for 5 years or more and lived in areas that received some type of intervention. These results show that there is a high degree of complexity involved in the risk for L. infantum infection and point out the need of developing new studies to perform a comprehensive analysis focused on investigating the interrelation between risk factors rather than their isolated roles on the determination of infection levels in urban areas.

In software engineering, Software Configuration Management is a set of support activities that allows for the orderly absorption of changes inherent to software development. For that, organization models for code versioning like Gitflow have been proposed. In Gitflow, two fixed branches (master and develop) are used to store the project history and be the starting point for changes. Despite the popularity of Gitflow for being considered a simple workflow, there are few: (a) reports of its use in practice and / or (b) documentation on how to deploy it in a real environment. This paper presents the process of adapting Gitflow and creating rules for its application in a real software development project. This adaptation took into account the opinions of managers and developers of a team of approximately 30 people within an agile Scrum life cycle. As a result, definitions and documents were generated to keep track of development, in addition to defining the necessary steps for its application considering the development process adopted by the team.
