Desafios e avanços na antibioticoterapia para exacerbações pulmonares na fibrose cística

A fibrose cística é uma doença genética complexa que afeta a produção de muco e a função pulmonar. Exacerbações pulmonares, muitas vezes provocadas por Pseudomonas aeruginosa, são comuns. O diagnóstico requer testes de suor e genéticos para guiar a terapia antibiótica. Avanços com moduladores CFTR melhoram a função pulmonar, mas desafios como resistência bacteriana persistem. Este estudo busca analisar a antibioticoterapia para exacerbações pulmonares na fibrose cística, com foco em abordagens inovadoras e personalizadas. O estudo, baseado em uma revisão sistemática da literatura científica, abrange o período de 2016 a 2024, utilizando as bases de dados PubMed (Medline), Cochrane Library e Scientific Electronic Library Online (SciELO). No primeiro estudo, sobre adjuvantes antibióticos no tratamento de infecções pulmonares em pacientes com fibrose cística, não houve impacto significativo nas exacerbações pulmonares ou na função respiratória. O KB001-A não alterou o tempo para a próxima administração de antibióticos em comparação ao placebo. Evidências apontam uma possível redução na densidade de Pseudomonas aeruginosa com o KB001-A e reduções em Staphylococcus aureus e quase-Pseudomonas aeruginosa com o óxido nítrico, sem diferenças na qualidade de vida. O segundo estudo, em um modelo suíno de pneumonia por Pseudomonas aeruginosa multirresistente, a terapia inalatória de amicacina combinada com meropenem mostrou maior eficácia bactericida nas secreções traqueais em comparação à monoterapia intravenosa. A administração inalatória não preveniu a disseminação da infecção, mas a amicacina evitou o aumento da concentração inibitória mínima de meropenem, com alta concentração nas amostras sem diferenças entre pulmões infectados e não infectados. No terceiro estudo, O estudo das nanopartículas poliméricas na eliminação de biofilmes bacterianos em cepas resistentes e suscetíveis associadas à fibrose cística mostrou potencial promissor contra bactérias multirresistentes. Os nanoportadores de lipídios demonstraram eficácia terapêutica significativa, ressaltando a necessidade de mais pesquisas para confirmar seu benefício clínico. Em resumo, os adjuvantes antibióticos não impactaram significantemente o tratamento de infecções pulmonares na fibrose cística. A combinação de amicacina e meropenem foi eficaz contra pneumonia por Pseudomonas aeruginosa multirresistente. As nanopartículas poliméricas e nanoportadores de lipídios mostraram potenciais terapêuticos promissores, demandando mais pesquisas para validar seus benefícios clínicos

Síndromes anêmicas: uma abordagem fisiopatológica sobre as principais considerações clínicas / Anemic syndromes: a pathophysiological approach to key clinical considerations

O seguinte artigo é uma revisão narrativa de literatura fundamentada nas plataformas do SciELO, LILACS, Pubmed, Google Acadêmico e Brazilian Journal of Health Review no período de janeiro a março de 2022. Atualmente, a anemia é algo que não é investigado sobre a sua etiologia e  sujeita a negligência, muitos pacientes são vítimas dos riscos de hemotransfusão e até privados de tratarem doenças que seriam possivelmente de manejo mais simples se detectadas precocemente. O seguinte artigo objetivou descrever as principais considerações sobre as síndrome anêmicas, em especial em sua  fisiopatologia e implicações clínicas. A temática de síndromes anêmicas é um tema complexo, que possui várias etiologias, apresentações clínicas, sintomatologias e meios diagnósticos. A terapêutica é focada em investigar o fator etiológico de base e simultaneamente tratar as implicações e aliviar o quadro clínico. Logo, o estudo em questão narra de modo detalhado a fisiopatologia da anemia e aborda as principais síndromes anêmicas para a clínica médica.

ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.

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
