The aim of this study is to investigate the impact of rotavirus vaccine on hospitalization rates for acute diarrhea in children younger than 5 years old after the introduction of the vaccine in 2006. A descriptive analytical observational study was carried out of the hospitalization rates occurred between 2000 and 2011 in 22 Regional Health Centers of Paraná State, Brazil. The effect of the vaccine was assessed by applying the SARIMA/Box-Jenkins time series methodology of intervention analysis, which allows verifying the slopes of the series are different after the introduction of the vaccine and estimating the magnitude of these effects for children younger than five years of age, by age group, for each region center. It was verified a statistically significant reduction by center/month on hospitalization rates for children 1 year old and younger, with averages of 47% and 58%, respectively, in December 2011.O objetivo desse estudo e investigar o impacto da vacina do rotavirus nas taxas de internacao por diarreia aguda em criancas menores de cinco anos apos a introducao da vacina em 2006.

Objective: To evaluate the risk of hospitalization for acute diarrhea in children under five, in the period of ten years before and after the oral rotavirus vaccine. Methods: Eco-descriptive-analyticstudy of the rates of hospitalization for acute diarrhea. We used hospitalization rate and the Relative Variation Rate to quantify the difference between the median in the years pre- andpostvaccination. We used logistic regression, odds ratio and attributablerisk to assess for the proportion of cases that could be avoided if exposure was avoided. Results: During the study period, the hospitalization rate was 117.41 per 10,000 children. In the prevaccination period, the median rate of hospitalization was 124.2/10,000 children. After the introduction of the vaccine, hospitalization rates were lower when compared to the median of the pre-vaccination years. Conclusion: There was a reduction in the hospitalization rates for acute diarrhea, thereby suggesting that the use of the vaccine and other associated factors can reduce the number of cases.

OBJECTIVE: To evaluate primary care prophylactic post-exposure anti-rabies treatment. METHODS: This was a cross-sectional, descriptive and analytical study, with data from the Information System for Notification of Diseases. It analyzed 39,087 visits, excluding 1,091 (2.79%) cases of re-exposure and pre-exposure, resulting in 37,996 post-exposure visits. A logistic regression analysis was performed for adjustment of the treatment. RESULTS: A predominance of Caucasians (83.93%), male (54.58%), primary school educational level (66.13%), ages between 20-59 years (45.0%) , followed by 0 to 12 years (32.88%), and residents in the urban area (91.97%) was observed. Among the visits, 15,500 (41.56%) were considered inadequate, 10,587 (28.11%) were deficient or the patient did not receive the necessary treatment, and 5,013 (13.44%) patients received more than what was necessary for rabies prophylaxis. CONCLUSION: The post-exposure prophylaxis for rabies was considered inadequate and requires a better approach on admission, and attention in completing the notification in the data record.

A diarreia por rotavirus e uma das principais causas de mortalidade em criancas nos paises em desenvolvimento, embora tenha sido observada a reducao nas taxas de hospitalizacao (HR) por diarreias aguda desde que a vacina do rotavirus foi introduzida. A dinâmica do rotavirus, no entanto, ainda e mal compreendida e picos sazonais ocorrem durante todo o ano, com variacoes entre paises e ao longo do tempo. O principal objetivo foi analisar o comportamento temporal das HR devido a diarreia aguda em criancas menores de um ano de idade no sul do Brasil, de 2000 a 2011, e investigar mudancas no padrao de sazonalidade apos a introducao da vacina contra o rotavirus em 2006. Analises harmonica e multiescala wavelet foram utilizadas para detectar a sazonalidade e pontos de mudanca na serie temporal. A significância estatistica de cada sazonalidade identificada foi testada pelo teste de Fisher. As analises harmonica e wavelet mostraram padroes sazonais anual e semestral das HR, bem como a nitida mudanca apos a introducao da vacina em 2006.Diarrhea by rotavirus is one of the main causes of mortality in children in developing countries, although the hospitalization rates (HR) for acute diarrhea have been found to have fallen since the introduction of the rotavirus vaccine. However, the patterns of the rotavirus are still not well understood and seasonal peaks occur throughout the year, with variations between countries and over time. The main objective of this study was to analyze the temporal behavior of HR caused by acute diarrhea in children under the age of one in the south of Brazil, between 2000 and 2011, and to explore changes in seasonality patters after the introduction of the vaccine against the rotavirus in 2006. Harmonic and multiscale wavelet analyses were used to detect seasonality and the points of change in the temporal scale. The statistical significance of each seasonality that was identified was tested using Fishers test. The harmonic and wavelet analyses show annual seasonal and six-monthly patterns for HR, as well as a clear change after the introduction of the vaccine in 2006.

No estudo de series temporais no dominio de frequencias, a analise de Fourier ou analise harmonica e bastante utilizada para encontrar periodicidades desconhecidas. Tal procedimento decompoe a serie em componentes periodicos, ou seja, a analise de Fourier corresponde a particao da variabilidade da serie em componentes de frequencias. Logo, como por ser visto em [2], considerando o modelo da serie temporal dado por uma combinacao linear de harmonicos (componentes senoidais) da seguinte forma [...]

Neste artigo, o comportamento espaco/temporal/sazonal das taxas de hospitalizacao por diarreia aguda em menores de um ano nas 6 macro regionais do estado do Parana, no periodo de 2000 a 2010 e analisado a partir de metodologias tanto no dominio do tempo quanto frequencia. Na analise de series temporais, sao frequentes os casos em que nao e possivel induzir a estacionariedade, de modo que a maioria dos metodos tradicionais para series temporais nao podem ser aplicados. Nesse sentido, a analise wavelets vem se mostrando como uma ferramenta importantissima. Uma versao modificada das wavelets, chamada de nao decimada, e invariante por translacao e tem propiciado excelentes resultados na analise de series temporais. E possivel realizar uma decomposicao da variância total da serie temporal em diferentes escalas. Diferentemente das usuais wavelets decimadas, o mesmo numero de coeficientes e mantido em cada escala na decomposicao, permitindo que toda correspondencia temporal seja mantida na analise. Uma vez que a variância de uma determinada serie e decomposta em diferentes escalas, fenomenos anteriormente ocultos podem ser revelados, tais como sazonalidades, variacoes ciclicas, pontos de mudanca, etc. Os resultados se mostraram promissores na investigacao do comportamento das internacoes e do rotavirus, principalemente em relacao a sazonalidade.
