    PM10 samples were collected in 2008 at three sites in South America in the framework of an international project (South American Emissions Megacities, and Climate; SAEMC). The concentration of metals, metalloids, ion and organic compounds of most PM10 samples collected at three sites (Buenos Aires (BAI), Bogotá (BOG) and São Paulo (SPA)) is below the air quality standard of the respective countries. At the sites n-alkanes and carbon preference index distribution indicated the influence of petroleum residues derived from vehicular emissions. Most PAH detected are attributed to light-duty gasoline vehicles and to stationary sources. At all sites benzo[a]pyrene equivalent values mean a significant cancer risk. Sulfate, nitrate, ammonium, calcium and sodium are the most abundant water-soluble ions at the three sites. Ammonium sulfate is likely the form presented for these species formed by photochemical reactions of precursors emitted mainly by vehicles. At BAI and SPA, formate/acetate ratios indicated the contribution of photochemical reactions; on the contrary, at BOG site, acetate is predominant, indicating strong contribution of vehicular emissions. São Paulo samples showed the highest concentrations of elements among all the sites. None of the toxic or potentially toxic elements exceed the guideline values of the World Health Organization. At BAI site earth crust seems to be the major source of Fe and Mn; at SPA, anthropogenic source is responsible for Pb and Zn presences. Traffic related element is well correlated at the three sites.Fil: Vasconcellos, Pérola C.. Universidade de Sao Paulo; BrasilFil: Souza, Davi Z..

    Este estudo analisa a estruturação da Rede de Atenção à Saúde nas regiões de saúde do estado de Mato Grosso, considerando as ações planejadas nos instrumentos de gestão do governo do estado e da Secretaria de Estado de Saúde (SES), nos anos de 2012 a 2017, em conformidade com as diretrizes da Portaria MS/GM nº 4.279, de 30 de dezembro de 2010, que orienta o processo de conformação das redes de atenção à saúde no âmbito do Sistema Único de Saúde (SUS). Trata-se de estudo qualitativo, de natureza exploratório-descritiva, do tipo documental, que analisou os documentos públicos referentes ao planejamento do governo na especificidade do setor de saúde, o que inclui o Plano Plurianual, o Plano Estadual de Saúde e o Plano Estratégico da SES. Os achados do estudo mostram que, embora algumas ações/atividades relacionadas às diretrizes da portaria estivessem contempladas nos documentos pesquisados, ainda não foram suficientes para o estabelecimento de uma rede de atenção regionalizada de qualidade e para o fortalecimento da Atenção Primária à Saúde (APS) com capacidade de ser coordenadora do cuidado e ordenadora da rede no estado de Mato Grosso.This study analyzes the structuring of the Health Care Network in the health regions of the state of Mato Grosso, considering the actions planned in the management instruments of the State government and the State Department of Health (SES), in the years of 2012 to 2017, in accordance with the guidelines of Ordinance MS/GM No 4.279, of December 30, 2010, which guides the process of conformation of Health Care Networks within the scope of the Brazilian National Health System (SUS). This is a qualitative, exploratory-descriptive study, of documentary type, which analyzed the public documents related to government planning on the specificity of the health sector, which includes the Pluriannual Plan, the State Health Plan and the Strategic Plan of the SES. The findings of the study show that, although some actions/activities related to the guidelines of the Ordinance were included in the researched documents, they were not yet sufficient for establishing a quality regionalized care network and for strengthening the Primary Health Care (PHC) with the capacity to coordinate care and order the network in the state of Mato Grosso

    Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Evaluation of in vitro testing strategies for hazard assessment of the skin sensitization potential of “real-life” mixtures : The case of henna-based hair-colouring products containing p-phenylenediamine

    Background: Allergic contact dermatitis caused by henna-based hair-colouring products has been associated with adulteration of henna with p-phenylenediamine (PPD). Objectives: To develop a testing approach based on in vitro techniques that address key events within the skin sensitization adverse outcome pathway in order to evaluate the allergenic potential of hair-colouring products. Methods: The following in vitro assays were used to test the sensitizing capacity of hair dye ingredients: the micro-direct peptide reactivity assay (mDPRA); the HaCaT keratinocyte-associated interleukin (IL)-18 assay; the U937 cell line activation test (U-SENS)/IL-8 levels; the blood monocyte-derived dendritic cell test; and genomic allergen rapid detection (GARD skin). Those techniques with better human concordance were selected to evaluate the allergenic potential of 10 hair-colouring products. Results: In contrast to the information on the label, chromatographic analyses identified PPD in all products. The main henna biomarker, lawsone, was not detected in one of the 10 products. Among the techniques evaluated by testing hair dye ingredients, the mDPRA, the IL-18 assay, GARD skin and the U-SENS correlated better with human classification (concordances of 91.7%-100%) and were superior to the animal testing (concordance of 78.5%). Thus, these assays were used to evaluate hair-colouring products, which were classified as skin sensitizers by the use of different two-of-three approaches. Conclusions: Our findings highlight the toxicological consequences of, and risks associated with, the undisclosed use of PPD in henna-based “natural” “real-life” products

    A brucelose canina por Brucella canis é uma doença infecto-contagiosa caracterizada principalmente por abortamentos e esterilidade nas fêmeas bem como orquite e epididimite nos machos. Além da grande importância econômica para criadores de cães, o caráter zoonótico da brucelose canina também deve ser considerado em virtude da complexa relação da população canina com os seres humanos. Deste modo, com o objetivo de pesquisar anticorpos anti Brucella canis em cães residentes na região metropolitana de Salvador, foram avaliadas 85 amostras de soro sanguíneo de cães domiciliados, machos e fêmeas, de idade e raças variadas através da técnica de imunodifusão em gel de agarose, com antígeno de membrana de Brucella ovis desenvolvido pelo Centro de Pesquisa Veterinária Desidério Finamor-RS (CPVDF). Os resultados encontrados indicaram uma soropositividade de 5,88% (5/85), demonstrando a presença de anticorpos anti-Brucella canis em cães residentes na região metropolitana de Salvador salientando a importância de maiores estudos desta zoonose
