     O câncer de próstata configura como importante causa de mortalidade em homens em cenário nacional e internacional. Atualmente há série de possibilidades terapêuticas para pacientes com diagnóstico de câncer de próstata. Nesse contexto, a cirurgia robótica emerge como uma abordagem inovadora no tratamento do câncer de próstata, oferecendo consideráveis ​​benefícios em comparação com as técnicas tradicionais. Este artigo de revisão explora a literatura existente para analisar os efeitos positivos da cirurgia robótica na eficácia do tratamento, recuperação pós-operatória e qualidade de vida dos pacientes com câncer de próstata. A metodologia empregada envolve a busca de artigos científicos relevantes em bases de dados especializadas, com foco em estudos publicados nos últimos anos. Na literatura pesquisada foi verificado que a cirurgia robótica apresenta potencial em melhorar de maneira significativa o pós-operatório de pacientes com câncer de próstata, melhorando tempo de recuperação, reduzindo dor, reduzindo de taxas de infecção de ferida operatória e reduzindo lesão nervosa de nervos envolvidos no processo de ereção peniana. Apesar dos inúmeros benefícios da cirurgia robótica é evidenciado que se trata de uma tecnologia de elevado custo operacional e de difícil implantação e aplicação em massa

    Cirurgia bariátrica e a redução de Diabetes e Hipertensão Arterial Sistêmica: revisão de literatura

    A obesidade atua como fator inflamatório importante no organismo humano, atuando e alterando significativamente a homeostase do indivíduo. Nesse contexto, a introdução da cirurgia bariátrica como prática terapêutica no controle de peso corporal tem se destacado como uma abordagem eficaz no tratamento da obesidade e suas comorbidades, incluindo diabetes mellitus tipo 2 (DM2) e hipertensão arterial sistêmica (HAS). Nesta revisão da literatura, exploramos estudos que investigam os efeitos da cirurgia bariátrica na redução do DM2 e da HAS, bem como os mecanismos subjacentes a essas melhorias. As buscas foram realizadas nas bases de dados PubMed, Scopus e Web of Science, utilizando termos de pesquisa relacionados à “cirurgia bariátrica”, “diabetes” e “hipertensão arterial sistêmica”. Dentre os estudos selecionados houve a constatação de uma sinalização benéfica do uso da cirurgia bariátrica no controle da obesidade e também na melhoria dos padrões pressóricos e também de redução da resistência insulínica. Conclui-se que a cirurgia bariátrica tem seu espaço no arsenal terapêutico de controle às patologias citadas, mas que sua indicação deve ser criteriosa e associada a melhora de hábitos de vida

    Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

    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

    Growing knowledge: an overview of Seed Plant diversity in Brazil

    Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
