    INTRODUCTION: Eugenia uniflora L. and Psidium cattleianum Sabine essential oils (EO) can be biologically active and serve as novel sources of antibiotics for Klebsiella pneumoniae and Acinetobacter baumannii bacteria.METHODS: The EO of E. uniflora L. (EOE) and P. cattleianum Sabine (EOP) were extracted from de leaves of the plants and chemically characterized by gas chromatography-mass spectrometry (GC-MS). The antioxidant potential was evaluated by the DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) technique and the cytotoxicity evaluated in mammalian VERO cell line by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The antibacterial activity of EOE and EOP was assessed by the broth microdilution method.RESULTS: The major compounds of EOE were benzofuran (24.38%), germacrene B (20.12%), ?-elemene (9.33%) and ?-cubebene (8.55%), and for EOP were ?-pinene (24.25%), ?-caryophyllene (20.45%), and eucalyptol (10.43%). Both EO tested showed low antioxidant effect and dose-dependent cytotoxicity in VERO cell line. The EOE was less toxic for the mammalian cells with an IC50 (half maximal inhibitory concentration) index of 75.0 mg.mL-1. The EOP and EOE were more active against A. baumannii, with a minimum inhibitory concentration (MIC) of 14.0 and 56.0 mg.mL-1 and a minimal bactericide concentration (MBC) of 14.0 and 112.0 mg.mL-1, respectively.  CONCLUSIONS: Although EOE and EOP have low antioxidant and antibacterial activity against A. baumanni and K. pneumoniae new approaches can be applied to improve this effect in vivo.

    As neoplasias hematológicas fazem parte de um grupo heterogêneo de doenças malignas que afetam os precursores hematopoiéticos sendo responsáveis por significativas taxas de mortalidade. O objetivo desse trabalho foi identificar a incidência dessas doenças na região de Três Lagoas, MS no período de janeiro de 2014 a julho de 2018. Foi baseado na análise de prontuários de pacientes com diagnóstico confirmado de leucemias, linfomas e mieloma múltiplo do Serviço de Oncologia do município de Três Lagoas, sendo os dados categorizados por: sexo, residência, faixa etária, raça, CID-10, ano de ingresso, diagnóstico, tratamento e evolução. Foram identificados 133 casos, com predomínio em indivíduos pardos (62,40%), do sexo masculino (60,9%) e idade de 70 a 79 anos (25,56%), procedentes do município (65,41%). O linfoma não-Hodgkin (LNH) foi o mais prevalente, correspondendo ao total de 45,11%, mais especificamente, o linfoma não-Hodgkin difuso de grandes células B (56,87%) e o linfoma folicular (13,73%). Foram identificados 9,77% de linfoma de Hodgkin, 18,4% de mieloma múltiplo e, dentre as leucemias crônicas, 5,26% foram as leucemias linfoides crônicas e 4,51% de leucemias mieloides crônicas. Dentre os tratamentos, a quimioterapia (68%) foi a mais utilizada e a biópsia foi método de diagnóstico mais solicitado. Os linfomas não-Hodgkin se consolidaram como maior taxa de óbitos (45%) reflexos da busca do serviço com doença em estadio e idade avançados. A pesquisa revela o retrato indireto de uma região, demonstrando a importância em ampliar o acesso à informação, minimizando o risco de aumento substancial no número de mortes por doenças onco-hematológicas

    Objective: To determine if the region served by the Unit of High Complexity Assistance in Oncology of Três Lagoas (HCAO - TL), an oncological reference in the Bolsão Sul-Matogrossense region, has similarity with the general average of cases of solid neoplasms in Brazil and the State, in addition to showing, through associations between the collected variables, possible factors that influence death in the region. Methods: Epidemiological cross-sectional study, based on medical records, including patients diagnosed with solid neoplasms, between January 2008 and December 2017. The epidemiological profile was assessed using the variables: sex, residence, age, race, ICD-10, year of diagnosis, stage, diagnosis, treatment and evolution, using the Quasi-Likelihood method. Results: Were identified, in this period,1,760 cases, showing that the region is similar to the national and state general average. With the associations, it has been demonstrated that proximity and access to specialized services reduces mortality. In addition, attention was drawn to the finding that younger individuals had more unfavorable outcomes, in addition to significant mortality in the white race. In addition, it was found that the survival rate is higher the lower the staging in the region. Final Considerations: The research, despite confirming the similarity with the general Brazilian and state average, can establish important correlations between the variables and the death outcome, drawing attention to the heterogeneous aspect of the studied region, bringing implications for management and care practice that it is necessary to seek the qualification and sustainability of cancer information systems, so that the results obtained create the appropriate means to face the challenges and support the development of effective actions for public health in Brazil.Objetivo: Determinar se a região atendida pela Unidade de Assistência de Alta Complexidade em Oncologia de Três Lagoas (UNACON - TL), referência oncológica no Bolsão Sul-Matogrossense, apresenta semelhança com a média geral de casos de neoplasias sólidas do Brasil e do Estado, além de evidenciar, através de associações entre as variáveis coletadas, possíveis fatores que exerçam influência sobre o óbito na região. Métodos: Estudo epidemiológico de delineamento transversal, baseado em prontuários, incluindo pacientes diagnosticados com neoplasias sólidas, entre janeiro de 2008 e dezembro de 2017. O perfil epidemiológico foi avaliado através das variáveis: sexo, residência, faixa etária, raça, CID-10, ano de diagnóstico, estádio, diagnóstico, tratamento e evolução, utilizando método da Quasi-Verossimilhança. Resultados: Foram identificados 1.760 casos neste período, podendo observar que a região tem semelhança com a média geral nacional e do estado. Com as associações, ficou demonstrado que a proximidade e o acesso ao serviço especializado diminui a mortalidade. Além disso, chamou atenção a verificação de que os indivíduos mais jovens tiveram desfechos mais desfavoráveis, além de uma significativa mortalidade na raça branca. No mais, constatou-se que a taxa de sobrevida é mais alta quanto menor foi o estadiamento na região. Considerações Finais: A pesquisa apesar de confirmar a semelhança com a média geral brasileira e do estado, pode estabelecer correlações importantes entre as variáveis e o desfecho óbito, chamando atenção para o aspecto heterogêneo da região estudada, trazendo implicações para a gestão e a prática assistencial de que é preciso buscar a qualificação e sustentabilidade dos sistemas de informação sobre câncer, para que os resultados obtidos criem os meios adequados para enfrentar os desafios e subsidiem o desenvolvimento de ações eficazes para a saúde pública no Brasil

    Discutir as representações sociais de discentes de um curso técnico de enfermagem acerca da problemática das drogas. Pesquisa qualitativa fundamentada na Teoria das Representações Sociais, envolvendo 98 discentes, para as quais foram aplicadas as técnicas de associação livre de palavras (TALP), grupo focal e entrevista. Os dados do TALP foram processados no software estatístico STATA. A identificação de termos com significância estatística norteou a análise de conteúdo para as demais técnicas, gerando duas categorias temáticas. A droga foi representada como objeto de destruição da pessoa, família e sociedade. A imagem da pessoa usuária de drogas aparece vinculada ao sexo masculino, jovem, de cor preta, morador da periferia e pobre. As representações sociais ressaltam aspectos de experiências e do contexto sociocultural das estudantes acerca das drogas, evidenciando demandas na formação dessas profissionais para integralidade da assistência

    Objective: to understand the perspective of health professionals on care for people with acquired immunodeficiency syndrome. Methods: this is a qualitative approach based on the Social Representation Theory based on the free speeches of 73 practitioners from four specialized public services, which were submitted to Factorial Correspondence Analysis. Results: practitioners with longer training and working time have emphasized aspects related to the syndrome such as physical degradation, abandonment and death; practitioners with shorter training and working time have represented the care of the person living with human immunodeficiency virus as an increased knowledge of sensitivity, indicating attitudes and behaviors socially constructed and accepted as belonging to health practitioners. Conclusion: practitioners with more experience have seen the syndrome in its negative and initial aspect; the newcomers to the professional practice have shown sensitivity and openness to the relevant issues of this phenomenon and concrete possibilities of more effective/transforming care practices

    International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
