Circulation of antibodies against yellow fever virus in a simian population in the area of Porto Primavera hydroeletric plant, São Paulo, Brazil

A febre amarela (FA) é doença infecciosa aguda de origem viral transmitida por mosquitos. No ciclo silvestre, o vírus é mantido por meio da infecção de macacos e da transmissão transovariana nos vetores. A vigilância sobre populações de primatas não humanos torna-se necessária para detectar a circulação viral, quando ainda está restrito a epizootias, e para determinar sua presença em regiões indenes ou de transição para a doença. Padronizou-se a técnica ELISA (Enzyme Linked Immunosorbent Assay) para determinar a prevalência de anticorpos da classe IgG contra o vírus da FA em soros de bugios (Alouatta caraya) da região do reservatório da Usina Hidrelétrica de Porto Primavera, SP. Foram testados soros de 570 macacos sendo que nenhuma amostra mostrou-se reativa para a presença de anticorpos contra o vírus da FA. Os resultados são coerentes com a epidemiologia da FA na região. Mesmo sendo área de transição, não se conhece, até o momento, ocorrência de epizootia ou surto de FA em humanos e investigações entomológicas não apontaram a presença de vetores para esta arbovirose. A técnica mostrou-se sensível, rápida e útil à vigilância epidemiológica como instrumento de busca ativa permitindo desencadear ações preventivas, como vacinação, antes mesmo do surgimento de epizootias

Síndrome metabólica: o novo desafio da Nutrição

A síndrome metabólica (SM) consiste em um conjunto de fatores de risco cardiovascular relacionados à obesidade abdominal e à resistência à insulina, refletindo no aumento da glicemia e da pressão arterial e na ocorrência de dislipidemia. Critérios recentes utilizados para a classificação da síndrome consideram a circunferência da cintura e a pressão arterial elevadas, pré-diabetes, hipertrigliceridemia e HDL colesterol reduzido. A SM pode aumentar consideravelmente o risco de desenvolvimento e de mortalidade por doenças e agravos não transmissíveis, como diabetes e doenças cardiovasculares. Sua ocorrência é multifatorial, envolvendo aumento ponderal, alimentação inadequada, inatividade física, predisposição genética e tabagismo. Ações preventivas mostram-se mais efetivas para a diminuição de riscos, quando comparadas ao tratamento de suas consequências, sendo importante a promoção da alimentação saudável, que envolve incentivo ao consumo de fibras e de gorduras insaturadas e moderação das saturadas e trans e de sódio

Política externa chilena e espectro ideológico político-partidário: um estudo sobre a Câmara dos Deputados (2002-2006)

The influence of political parties on decisions made by members of Congress is a hotly debated issue in political science. In foreign policy, which is usually considered nonpartisan, the matter is even more inconclusive. The current study analyzes all the roll-call votes taken on foreign policy issues in the 2002-2006 legislature of the Chilean Chamber of Deputies. After tracing a spatial map of foreign policy preferences among Chilean Deputies using the Nominate statistical package, we concluded that the ideology of the legislator's political party is a predictive factor for his or her foreign policy behavior. Our findings indicate that the way Chilean legislators structure their preferences on foreign policy issues does not differ significantly from the way they shape their domestic policy preferences.

LEACHATE TREATMENT PROCESS AT A MUNICIPAL STABILIZED LANDFILL BY CATALYTIC OZONATION: AN EXPLORATORY STUDY FROM TAGUCHI ORTHOGONAL ARRAY

Catalytic ozonation has been recognized in the scientific community as an efficient technique, reaching elevated rates of recalcitrant organic material mineralization, even at the presence of scavenger species of hydroxyl free radicals. This study presents the most significant factors involving the leachate treatment stabilized by the municipal landfill of the city of Guaratingueta, State of Sao Paulo, Brazil, by using a catalytic ozonation activated by metallic ions Fe(3+), Zn(2+), Mn(2+), Ni(2+) and Cr(3+). The Taguchi L(16) orthogonal array and its associated statistical methods were also used in this study. Among the researched ions, the most notable catalysis was obtained with ferric ion, statistically significant in the reduction of COD with a confidence level of 99.5%.

Constitutive model for long term municipal solid waste mechanical behavior

This paper presents some improvements in the model proposed by Machado et al. [Machado SL, Carvalho MF, Vilar OM. Constitutive model for municipal solid waste. J Geotech Geoenviron Eng ASCE 2002; 128(11):940-51] now considering the influence of biodegradation of organic matter in the mechanical behavior of municipal solid waste. The original framework considers waste as composed of two component groups; fibers and organic paste. The particular laws of behavior are assessed for each component group and then coupled to represent waste behavior. The improvements introduced in this paper take into account the changes in the properties of fibers and mass loss due to organic matter depletion over time. Mass loss is indirectly calculated considering the MSW gas generation potential through a first order decay model. It is shown that as the biodegradation process occurs the proportion of fibers increases, however, they also undergo a degradation process which tends to reduce their ultimate tensile stress and Young modulus. The way these changes influence the behavior of MSW is incorporated in the final framework which captures the main features of the MSW stress-strain behavior under different loading conditions.

Opportunistic and partisan election cycles in Brazil: new evidence at the municipal level

This article tests the hypothesis of opportunistic and partisan cycle models using a new large data set of Brazilian municipalities over the 1989-2005 period. The results show an increase in total and current expenditures and a decrease in municipal investments, local tax revenues, and budget surplus in election years. They also show that partisan ideology exerts a relative influence on the performance of the local public accounts. These results confirm that both opportunistic and partisan cycles have occurred in the management of the budgets of Brazilian municipalities after the end of the military government.

De novo mutations of the Patched gene in nevoid basal cell carcinoma syndrome help to define the clinical phenotype

The demonstration that mutations in the Patched (PTCH) gene cause nevoid basal cell carcinoma syndrome (NBCCS) has led to the identification of the exact molecular lesion in a percentage of individuals with the syndrome, In addition, it has been possible to determine, through molecular analysis of parents and other relatives of these individuals, if the mutation is inherited or has arisen de novo, We have previously reported 28 mutations in individuals with NBCCS, and here we present an additional 4 novel mutations, We have also analyzed relatives of a number of the individuals in whom we have found mutations, In total we have identified 8 individuals who carry a de novo mutation in the PTCH gene, In 5 of these cases, clinical and radiological examination had not unequivocally ruled out a diagnosis in one of the parents, This helps to define the clinical phenotype and suggests that diagnostic criteria in this complex syndrome may require review.

De novo copy number variants identify new genes and loci in isolated sporadic tetralogy of Fallot

Tetralogy of Fallot (TOF), the most common severe congenital heart malformation, occurs sporadically, without other anomaly, and from unknown cause in 70% of cases. Through a genome-wide survey of 114 subjects with TOF and their unaffected parents, we identified 11 de novo copy number variants (CNVs) that were absent or extremely rare (<0.1%) in 2,265 controls. We then examined a second, independent TOF cohort (n = 398) for additional CNVs at these loci. We identified CNVs at chromosome 1q21.1 in 1% (5/512, P = 0.0002, OR = 22.3) of nonsyndromic sporadic TOF cases. We also identified recurrent CNVs at 3p25.1, 7p21.3 and 22q11.2. CNVs in a single subject with TOF occurred at six loci, two that encode known (NOTCH1, JAG1) disease-associated genes. Our findings predict that at least 10% (4.5-15.5%, 95% confidence interval) of sporadic nonsyndromic TOF cases result from de novo CNVs and suggest that mutations within these loci might be etiologic in other cases of TOF.

Distribution of Hemoglobin Phenotypes in Four Different Districts of Porto Velho, Rondonia, Brazil

Hemoglobin profile studies have been carried out in four samples from different districts of Porto Velho (Rondonia State) in the western Amazonian region of Brazil: Candelaria, Bate Estaca, Hemeron (at the State Blood Bank), and Sao Carlos. Samples from 337 unrelated individuals were collected during medical and paramedical team visits by professionals from the Instituto de Pesquisa em Patologia Tropical and the Centro de Pesquisa em Patologias Tropicais (both research institutes in tropical diseases). The aim of this study is to assess the frequency of alleles in the hemoglobin system, mainly alleles HB*A, *S, and *E. The overall phenotype frequencies were FIB A,S = 0.025, HB A,E = 0.006, and HB A,A = 0.969. Samples from the blood bank subjects and samples from the homogeneous areas of Silo Carlos and Candelaria plus Bate Estaca have a chi-square of heterogeneity of 6.383 (p = 0.041) and 8.406 (p = 0.015), respectively. The allele frequencies (HB*A = 0.984, HB*S = 0.012, and HB*E = 0.003) do not significantly differ from frequencies found in other Brazilian regions.

Impacts of Animal Traffic on the Brazilian Amazon Parrots (Amazona species) Collection of the Quinzinho de Barros Municipal Zoological Park, Brazil, 1986-2007

Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. Zoo Biol 29:600-614, 2010. (C) 2010 Wiley-Liss, Inc.

Projeto porto sem papel

O setor portu??rio envolve uma grande diversidade de usu??rios e ??rg??os intervenientes, cada um com suas normas e processos pr??prios. Tal situa????o, associada ao fato de que todo o fluxo de informa????es e documentos solicitados pelos ??rg??os aos usu??rios era realizado em papel, n??o permitia clareza e efici??ncia na troca de informa????es. A falta de dados confi??veis e tempestivos tamb??m n??o permitia efetividade na gest??o e planejamento do setor. Nesse contexto, foi implantado, na fase inicial do Porto Sem Papel, um sistema que permitia a troca de informa????es e documentos digitais entre os usu??rios e os diversos ??rg??os intervenientes. Assim, os fluxos de informa????es e documentos, que antes eram realizados em papel, passaram a ser realizados digitalmente, dando agilidade e transpar??ncia aos processos. Cabe destacar que todas as informa????es est??o presentes agora em uma base ??nica de dados, o que permite a realiza????o de an??lises que subsidiem a gest??o e a melhoria de processos no setor portu??rio

O Sistema de Gest??o de Conv??nios e Contratos de Repasse (Siconv) ?? a iniciativa do Governo Federal respons??vel por todo o ciclo de vida dos conv??nios, contratos de repasse e termos de parceria, no qual s??o registrados os atos, desde a formaliza????o da proposta at?? a presta????o de contas final. O Siconv inova no modelo de gest??o, proporciona celeridade aos procedimentos e desburocratiza as atividades fins, com foco na substitui????o do processo f??sico pelo eletr??nico e no registro de todos os procedimentos, o que permite maior transpar??ncia na execu????o das transfer??ncias volunt??rias da Uni??o. Destaca- se ainda que a disponibiliza????o do sistema aos usu??rios e tamb??m para a sociedade por meio do endere??o eletr??nico www.convenios.gov.br deve ser considerada como grande fator de inova????o, uma vez que, mesmo indiretamente, se apresenta como mais uma ferramenta de controle social.

Registro eletr??nico do atendimento ambulatorial: mais um passo na consolida????o do prontu??rio eletr??nico do paciente no Hospital de Cl??nicas de Porto Alegre

O Hospital de Cl??nicas de Porto Alegre, como hospital universit??rio, tem a miss??o de oferecer servi??os assistenciais ?? comunidade, ser ??rea de ensino para a Universidade Federal do Rio Grande do Sul e promover a realiza????o de pesquisas. At?? 2004, todo o registro do atendimento ambulatorial vinha sendo realizado manualmente, ao contr??rio dos registros do atendimento de interna????o, que, na sua quase totalidade, j?? estavam informatizados no Prontu??rio On-Line. Em decorr??ncia, registros incompletos, n??o padronizados e, muitas vezes, ileg??veis eram freq??entes. A informatiza????o do ambulat??rio foi um projeto com n??vel de criticidade alt??ssimo, exigindo reformula????o completa da infra-estrutura existente e gerenciamento adequado dos riscos envolvidos. O sistema ?? hoje utilizado em 145 consult??rios, por 188 equipes de sa??de, que atendem a uma m??dia di??ria de 2 mil consultas, de modo que o sistema tem proporcionado melhoria na qualidade e completude da informa????o
