Use of Poisson spatiotemporal regression models for the Brazilian Amazon Forest: malaria count data

INTRODUÇÃO: A malaria é uma doença endêmica na região da Amazônia Brasileira, e a detecção de possíveis fatores de risco pode ser de grande interesse às autoridades em saúde pública. O objetivo deste artigo é investigar a associação entre variáveis ambientais e os registros anuais de malária na região amazônica usando métodos bayesianos espaço-temporais. MÉTODOS: Utilizaram-se modelos de regressão espaço-temporais de Poisson para analisar os dados anuais de contagem de casos de malária entre os anos de 1999 a 2008, considerando a presença de alguns fatores como a taxa de desflorestamento. em uma abordagem bayesiana, as inferências foram obtidas por métodos Monte Carlo em cadeias de Markov (MCMC) que simularam amostras para a distribuição conjunta a posteriori de interesse. A discriminação de diferentes modelos também foi discutida. RESULTADOS: O modelo aqui proposto sugeriu que a taxa de desflorestamento, o número de habitants por km² e o índice de desenvolvimento humano (IDH) são importantes para a predição de casos de malária. CONCLUSÕES: É possível concluir que o desenvolvimento humano, o crescimento populacional, o desflorestamento e as alterações ecológicas associadas a estes fatores estão associados ao aumento do risco de malária. Pode-se ainda concluir que o uso de modelos de regressão de Poisson que capturam o efeito temporal e espacial em um enfoque bayesiano é uma boa estratégia para modelar dados de contagem de malária.

Disparity between Multilocus Enzyme Electrophoresis, Microsatellite Markers and Pulsed-Field Gel Electrophoresis in epidemiological tracking of Candida albicans

Various molecular systems are available for epidemiological, genetic, evolutionary, taxonomic and systematic studies of innumerable fungal infections, especially those caused by the opportunistic pathogen C. albicans. A total of 75 independent oral isolates were selected in order to compare Multilocus Enzyme Electrophoresis (MLEE), Electrophoretic Karyotyping (EK) and Microsatellite Markers (Simple Sequence Repeats - SSRs), in their abilities to differentiate and group C. albicans isolates (discriminatory power), and also, to evaluate the concordance and similarity of the groups of strains determined by cluster analysis for each fingerprinting method. Isoenzyme typing was performed using eleven enzyme systems: Adh, Sdh, M1p, Mdh, Idh, Gdh, G6pdh, Asd, Cat, Po, and Lap (data previously published). The EK method consisted of chromosomal DNA separation by pulsed-field gel electrophoresis using a CHEF system. The microsatellite markers were investigated by PCR using three polymorphic loci: EF3, CDC3, and HIS3. Dendrograms were generated by the SAHN method and UPGMA algorithm based on similarity matrices (S(SM)). The discriminatory power of the three methods was over 95%, however a paired analysis among them showed a parity of 19.7-22.4% in the identification of strains. Weak correlation was also observed among the genetic similarity matrices (S(SM)(MLEE) x S(SM)(EK) x S(SM)(SSRs)). Clustering analyses showed a mean of 9 +/- 12.4 isolates per cluster (3.8 +/- 8 isolates/taxon) for MLEE, 6.2 +/- 4.9 isolates per cluster (4 +/- 4.5 isolates/taxon) for SSRs, and 4.1 +/- 2.3 isolates per cluster (2.6 +/- 2.3 isolates/taxon) for EK. A total of 45 (13%), 39(11.2%), 5 (1.4%) and 3 (0.9%) clusters pairs from 347 showed similarity (Si) of 0.1-10%, 10.1-20%, 20.1-30% and 30.1-40%, respectively. Clinical and molecular epidemiological correlation involving the opportunistic pathogen C. albicans may be attributed dependently of each method of genotyping (i.e., MLEE, EK, and SSRs) supplemented with similarity and grouping analysis. Therefore, the use of genotyping systems that give results which offer minimum disparity, or the combination of the results of these systems, can provide greater security and consistency in the determination of strains and their genetic relationships.

Isozyme characterization of Eucalyptus urophylla (S.T. Blake) and E-grandis (Hill ex Maiden) populations in Brazil

Seedling taken from 2 species of Eucalyptus growing in Brazil were electrophoretically analysed at 14 isozyme loci representing 6 enzyme systems: alpha-EST, beta-EST, SKDH, IDH, MDH, and LAP. Genetic variability measures were determined using 11 putative isozyme loci. on average, 81.8% and 54.5% of the loci were found to be polymorphic by the criterion of 95% in E. urophylla and E. grandis, respectively. The mean number of alleles per loci was 3.0 in E. urophylla and 2.5 in E. grandis. Observed mean heterozygosity was 0.283 in E. urophylla and 0.166 in E. grandis. Levels of genetic diversity in these species were similar to those in other Eucalyptus species which have widespread distributions. The possible hybridization of E. urophylla with E. alba is also discussed.

Prevalence of deciduous tooth erosion in childhood

Objectives: The objective of this study was to estimate the prevalence of deciduous tooth erosion and to identify possible associations with sex, age and toothbrushing frequency in children aged 4-6 years. Methods: The sample was drawn from attendants (n = 7058) of 57 public preschools in a Brazilian city. Tooth wear index was used to evaluate erosion. Descriptive statistical analysis consisted of the calculation of the prevalence of dental erosion; chi-squared and Fisher's exact tests were performed to verify the association between dental erosion and sex, age and toothbrushing frequency. Results: Two thousand and seven hundred and fifty-nine preschool students were examined. Deciduous tooth erosion was observed in 0.6% of children and its incidence did not differ between sexes. The highest prevalence was observed in children aged 6 years (58.3%) and the most affected sextants were the fourth (22.86%) and sixth (20.00%), indicating that lingual and occlusal tooth surfaces were most frequently involved. The degree of involvement was classified as incipient in 54.29% of children and moderate in 45.71%. The significance level was set at 5%. No association was found between erosion and sex, age or toothbrushing frequency. Conclusions: The prevalence of deciduous tooth erosion was low in Brazilian children, and this disorder is not considered a public health problem in this part of the population. © 2013 John Wiley & Sons A/S.

Aspectos físicos e sociais da geografia da disponibilidade hídrica municipal no Brasil

In managing water resources, indexes are used to simplify and quantify available information as well as report the characteristics of a region under study. These indexes may be extremely demanding concerning information required, or very simple, and the water poverty index and Falkenmark index are examples of both extreme situations, respectively. Searching for an index that considers regional and local complexities and information available in developing countries, a new index was developed to evaluate the population accessibility to water resources. This new index combines the Human Development Index and Falkenmark Index and geographic information systems. The results are presented in figures which show the situation at national level, highlighting that the Northeast and Southeast regions are the most vulnerable in Brazil.

Desenvolvimento humano: a realidade além dos números

The book-report Human Development: the reality beyond the numbers addresses issues related to the Development Index (IDH), of Brazil, in a general context, and the city of Bauru, in the local context. The “IDH” is a number that serves as a comparison between countries, in order to measure the degree of economic development and the quality of life offered to the population. The classification, if high, can be readily used as a means of aggrandizement national and if low, can be used to highlight the weaknesses national. Understanding the role of media as an agent capable of promoting social debates of great importance, this book-report aims to discuss the concept of human development beyond the numbers commonly reported, prompting debates on the issue of human development: whether in relation to social issues, public policy or the role of the media in the process of contributing to the formation of public opinion. The methodology used was the data collection and the research literature, besides journalistic techniques, such as interview, report and profile
