The evidence gathered during this study provides estimates of carriage prevalence in Brazilian adolescents, showing an unusually high dominance of serogroup C. These results have important implications in future strategies to optimize the impact of the current meningococcal C vaccination program in Brazil.

Objective:To assess the completeness and reliability of the Information System on Live Births (Sinasc) data.Methods:A cross-sectional analysis of the reliability and completeness of Sinasc's data was performed using a sample of Live Birth Certificate (LBC) from 2009, related to births from Campinas, Southeast Brazil. For data analysis, hospitals were grouped according to category of service (Unified National Health System, private or both), 600 LBCs were randomly selected and the data were collected in LBC-copies through mothers and newborns' hospital records and by telephone interviews. The completeness of LBCs was evaluated, calculating the percentage of blank fields, and the LBCs agreement comparing the originals with the copies was evaluated by Kappa and intraclass correlation coefficients.Results:The percentage of completeness of LBCs ranged from 99.8%-100%. For the most items, the agreement was excellent. However, the agreement was acceptable for marital status, maternal education and newborn infants' race/color, low for prenatal visits and presence of birth defects, and very low for the number of deceased children.Conclusion:The results showed that the municipality Sinasc is reliable for most of the studied variables. Investments in training of the professionals are suggested in an attempt to improve system capacity to support planning and implementation of health activities for the benefit of maternal and child population.

In this work, the effects of particle size and density on the fluid dynamic behavior of vertical gas-solid transport of Group D particles in a 53.4 mm diameter transport tube were studied. For the conditions tested, the experimental curves of pressure gradient versus air velocity presented a minimum pressure gradient point, which is associated with a change in the flow regime from dense to dilute phase. The increases in particle size from 1.00 to 3.68 mm and in density from 935 to 2500 kg/m³ caused an increase in pressure gradient for the dense-phase transport region, but were not relevant in dilute transport. The transition velocity between dense and dilute flow (Umin) also increased with increasing particle density and diameter. An empirical equation was fitted for predicting transition air velocity for the transport of glass spheres. Additional experiments, covering a wider range of conditions and particles properties, are still needed to allow the fitting of a generalized equation for prediction of Umin

The authors describe an outbreak of American cutaneous leishmaniasis from February 1993 to September 1994 in the districts of Sousas and Joaquim Egídio, Campinas, São Paulo State. Out of a total of 25 cases, seven occurred in the countryside, nine in the periurban area, and nine in the urban area. The authors observed a shift in the occurrence of leishmaniasis cases from rural to urban areas. Cases in males predominated over females (60%/40%). Some 44% of the cases occurred in individuals ranging from 11 to 30 years of age. Some 48% of cases occurred in students, domestic workers, and housewives. In 90% of the cases, the disease presented as a single lesion, located predominantly on the upper and lower limbs. The appearance of cases in the region is probably related to the expansion of urban areas occurring in the 1970s and 1980s, a trend which intensified further more recently.

OBJETIVOS Analisar a magnitude das mudanças na incidência e mortalidade por câncer do colo do útero (CCU) e câncer de mama (CM) em Campinas (SP) entre os quinquênios 1991–1995 e 2010–2014. MÉTODOS Os dados sobre câncer foram obtidos do Registro de Câncer de Base Populacional de Campinas e os dados sobre óbitos do Sistema de Informação de Mortalidade do Departamento de Informática do Sistema Único de Saúde. Foram calculadas taxas de incidência e de mortalidade padronizadas por idade pelo método direto, com os respectivos intervalos de confiança de 95%. Mensurou-se a magnitude das mudanças por meio da razão de taxas (RT). RESULTADOS Entre os períodos estudados, houve aumento de três vezes na taxa de detecção do CCU in situ (RT = 3,03; IC95% 2,64–3,47) e de 5 vezes para o CM in situ (RT = 5,23; IC95% 4,98–5,50). A proporção de casos de CM in situ em relação ao total de casos de CM aumentou de 3,31% para 11,05%. A taxa de incidência do CCU invasivo declinou em 57% (RT = 0,43; IC95% 0,40–0,47), e a do CM invasivo aumentou em 40% (RT = 1,40; IC95% 1,33–1,47). A taxa de mortalidade do CCU caiu em 58% (RT = 0,42; IC95% 0,32–0,56), e a do CM em 15% (RT = 0,85; IC95% 0,82–0,89). CONCLUSÃO A incidência de carcinomas in situ de CCU e CM aumentou nessas quase duas décadas. A taxa de carcinoma invasivo do CCU diminuiu, e a do CM aumentou. A mortalidade pelos dois cânceres foi reduzida. Observar essas alterações é útil para avaliar o impacto das ações realizadas no período e planejar ações futuras.
