Population dynamics of DENV-1 genotype V in Brazil is characterized by co-circulation and strain/lineage replacement

Following successive outbreaks of dengue fever caused predominantly by dengue virus (DENV) 2 and 3, DENV-1 is now the primary serotype circulating in Brazil. We sequenced and analyzed Brazilian DENV-1 genomes and found that all isolates belong to genotype V and are subdivided into three lineages, which were introduced during four different events. The first introduction occurred in 1984-85, the second in 1997-99, and the third and fourth occurred from 2004 to 2007. These events were associated with an increase in genetic diversity but not with positive selection. Moreover, a potential new recombinant strain derived from two distinct lineages was detected. We demonstrate that the dynamics of DENV-1 in Brazil is characterized by introduction, movement, local evolution, and lineage replacement. This study strengthens the relevance of genotype surveillance in order to identify, trace, and control virus populations circulating in Brazil and Latin America.Conselho Nacional de Pesquisas (Brazil) Conselho Nacional de Desenvolvimento Cientifico e TecnologicoFundação de Amparo à Pesquisa do Estado de Minas Gerai

CELEBRANDO A NAÇÃO NOS GRAMADOS: O CAMPEONATO SUL-AMERICANO DE FUTEBOL DE 1922

Esse artigo tem por objetivo analisar um momento da história brasileira no qual o esporte foi mobilizado com o intuito de celebrar a nação: a realização de um campeonato sul-americano de futebol no âmbito dos festejos do centenário da independência, organizados na Capital Federal em 1922. Para alcance do objetivo, como fontes foram utilizadas revistas e jornais de grande circulação do Rio de Janeiro e de São Paulo. O intuito foi analisar a competição em sua materialidade, em sua funcionalidade e em seu teor simbólico. Buscamos perceber como os dirigentes procuraram fazer do evento uma concretização de seus desejos de celebração da nação e também como o público se apropriou à sua maneira dessa iniciativa, a partir da relação estabelecida com a seleção brasileira de futebol

Milling of the Phosphate Rock Flotation Circuit Circulating Load Aiming Production Increase and Iron Content Reduction in the Final Concentrate

Phosphorus has its main application in the production of phosphoric acid, being the apatite series its main ore. The Brazilian main phosphorus reserves are igneous, as is the case of Catalão alkaline dome, were Copebras/CMOC International has operations. The content of P2O5 in the ROM has been reduced over the years and, as a consequence, the content of the contaminants in the concentrate, produced by flotation, which enhances the difficulty in the phosphoric acid production. Only traces of arsenic, iron, and heavy metals can be present in high-purity phosphoric acid. The circulating load of the Copebras’ phosphate rock flotation circuit was submitted to bench scale flotation tests with addition of a milling step were carried out in order to increase the recovery of P2O5 and the reduction of the Fe2O3 content to values below 5%. Samples were collected from the flow composed by the scavenger concentrate and cleaner tail, with d95 \u3c208 \u3eμm and average content of 26.2% of P2O5 and 13% of Fe2O3 (6% hematite, 5% goethite, 1% magnetite, and 1% ilmenite) and comminuted in a pilot pant rod mill. Three samples with different d95 (2O3 content (for the sample with d95 \u3c150 \u3eμm). The industrial implementation of a milling stage of the flotation circulation load and a subsequent flotation of this material has the potential to increase the overall process efficiency by approximately 5.5%, resulting in a production increase of 62,000 tons/year of phosphate rock concentrate, with higher quality than the one currently produced. The phosphate rock flotation tailings feeds a niobium processing plant, a co-product of extreme importance due to its economic value. The proposed circuit increased the niobium liberation degree and its content in the produced tailings, which will probably lead to a higher recovery of the same

Evaluation of the patient with temporomandibular dysfunction : what are the steps to arrive at a correct diagnosis?

Temporomandibular disorders are heterogeneous group of disorders involving the temporomandibular joint, masticatory muscles and associated structures. With a multifactorial origin, usually the patient with mandibular temporomandibular disorder reports multiple complaints, associated or not to comorbidities and non-repairing sleep. Anamnesis directed to the correct diagnosis is fundamental for the elaboration of a successful therapy. The diagnostic process should be able to categorize the pain as well as identify the involved tissues in addition to pointing out the specific source of pain within that tissue system. The steps to arrive at a correct diagnosis should cover: anamnesis, clinical evaluation for temporomandibular joint, the clinical examination through inspection of the cranial nerves, intra-oral evaluation and musculoskeletal examination, imaging tests, anesthetic block diagnosis, laboratory tests and evaluation of sleep pattern. This process begins in the clinical history, presence or not of associated comorbidities, sleep pattern and other factors that may somehow contribute to the patient’s clinic. This information supports the correct diagnosis and is essential for adequate and successful therapy.info:eu-repo/semantics/publishedVersio

Immune Modulation in Primary Vaccinia virus Zoonotic Human Infections

In 2010, the WHO celebrated the 30th anniversary of the smallpox eradication. Ironically, infections caused by viruses related to smallpox are being increasingly reported worldwide, including Monkeypox, Cowpox, and Vaccinia virus (VACV). Little is known about the human immunological responses elicited during acute infections caused by orthopoxviruses. We have followed VACV zoonotic outbreaks taking place in Brazil and analyzed cellular immune responses in patients acutely infected by VACV. Results indicated that these patients show a biased immune modulation when compared to noninfected controls. Amounts of B cells are low and less activated in infected patients. Although present, T CD4+ cells are also less activated when compared to noninfected individuals, and so are monocytes/macrophages. Similar results were obtained when Balb/C mice were experimentally infected with a VACV sample isolated during the zoonotic outbreaks. Taking together, the data suggest that zoonotic VACVs modulate specific immune cell compartments during an acute infection in humans

Relato de caso: atonia uterina / Case report: uterine atony

A atonia uterina corresponde a um estado de perda da contratilidade da musculatura uterina no período pós-parto imediato o que aumenta o risco de hemorragia pós-parto (HPP). É fundamental que os sinais de atonia uterina sejam identificados de forma precoce para prevenir complicações. Além disso é imprescindível uma equipe multidisciplinar que realize a monitorização da paciente e que esteja apta para atuar em casos de complicações Objetivos: Identificar os sinais de gravidade nos quadros de atonia uterina e como realizar o manejo dessa paciente. Métodos: Revisão bibliográfica, cujo levantamento de referências ocorreu entre os meses de fevereiro a abril de 2018. Foi realizada busca nas The Lancet e Scielo, empregando-se os termos: atonia uterina; hipotonia uterina; hemorragia pós-parto, prevenção para atonia. Os critérios de inclusão foram artigos cujas abordagens contivessem aspectos pertinentes ao trabalho, com ano de publicação entre 2015 e 2018. Foram descartadas as fontes que não continham conteúdo adequado para a confecção deste trabalho. Foram utilizadas 10 referências bibliográficas incluído livros físicos sobre o assunto abordado.  Discussão: Existem diversas causas para HPP, dentre elas a atonia uterina. É fundamental observar as todas as pacientes após o parto, uma vez que, a maioria das pacientes que desenvolvem o quadro não possuem fatores de risco prévio. Além disso, a principal formar de prevenção é adotar uma conduta ativa no terceiro estágio do trabalho de parto, que consiste na administração de droga uterotônica após o desprendimento do ombro anterior e tração controlada do cordão umbilical. Conclusão: É sempre importante observar os sinais vitais, bem a quantidade de sangue perdida pela paciente para tomar medidas o mais precoce possível. Além disso é fundamental uma equipe multiprofissional apta para atuar no manejo adequado. Por fim é de extrema importância a realização de medidas preventivas para evitar complicações e até mesmo o óbito materno

Circulation of Different Lineages of Dengue Virus 2, Genotype American/Asian in Brazil: Dynamics and Molecular and Phylogenetic Characterization

The American/Asian genotype of Dengue virus type 2 (DENV-2) was introduced into the Americas in the 80′s. Although there is no data showing when this genotype was first introduced into Brazil, it was first detected in Brazil in 1990. After which the virus spread throughout the country and major epidemics occurred in 1998, 2007/08 and 2010. In this study we sequenced 12 DENV-2 genomes obtained from serum samples of patients with dengue fever residing in São José do Rio Preto, São Paulo (SJRP/SP), Brazil, in 2008. The whole open reading frame or envelope sequences were used to perform phylogenetic, phylogeographic and evolutionary analyses. Isolates from SJRP/SP were grouped within one lineage (BR3) close to isolates from Rio de Janeiro, Brazil. Isolates from SJRP were probably introduced there at least in 2007, prior to its detection in the 2008 outbreak. DENV-2 circulation in Brazil is characterized by the introduction, displacement and circulation of three well-defined lineages in different times, most probably from the Caribbean. Thirty-seven unique amino acid substitutions were observed among the lineages, including seven amino acid differences in domains I to III of the envelope protein. Moreover, we dated here, for the first time, the introduction of American/Asian genotype into Brazil (lineage BR1) to 1988/89, followed by the introduction of lineages BR2 (1998–2000) and BR3 (2003–05). Our results show a delay between the introduction and detection of DENV-2 lineages in Brazil, reinforcing the importance and need for surveillance programs to detect and trace the evolution of these viruses. Additionally, Brazilian DENV-2 differed in genetic diversity, date of introduction and geographic origin and distribution in Brazil, and these are important factors for the evolution, dynamics and control of dengue.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq Grant )Fundação de Amparo à Pesquisa do Estado de São PauloFundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG grant
