Associação da síndrome inflamatória multissistêmica pediátrica e a covid-19 / Association of pediatric multisystem inflammatory syndrome and covid-19

Objetivo: Analisar evidências disponíveis na literatura sobre a associação da Síndrome Inflamatória Multissistêmica Pediátrica (SIM-P) e a Covid-19. Metodologia: Trata-se de um levantamento bibliográfico, de caráter exploratório, com abordagem qualitativa. Foram realizadas buscas nas bases de dados da Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO) e materiais disponíveis na plataforma Google Acadêmico no período de 2020 e 2021. Resultados: O estudo traz discussões sobre o quadro clínico de crianças que cursaram com processos de infecção provavelmente associada por SARS-CoV-2. Os casos registrados mostram três fases da doença, onde algumas crianças tiveram sintomas leves ou assintomáticos, e outras evoluíram para casos mais graves, com evidências laboratoriais de infecção ou inflamação, incluindo concentrações elevadas de PCR. De acordo com dados da Covid-19 desde o início da pandemia, as crianças eram as menos afetadas ou cursavam com sintomatologia mais suave. No entanto, verificou-se que houve um aumento significativo no número de crianças com a SIM-P, podendo estar relacionada diretamente com o vírus, levando a um alerta para os profissionais e as autoridades de saúde sobre o assunto. Conclusão: A SIM-P é provavelmente de origem imunológica, mediada por anticorpos, possui algumas similaridades com a doença de Kawasaki, porém com critérios laboratoriais diferentes. Uma das comprovações da SIM-P ser uma síndrome pós-infecciosa, é cursar com provas virológicas frequentemente negativas e somente anticorpos IgG positivos, sendo assim relacionada diretamente pela Covid-19

Spatial analysis of probable cases of dengue fever, chikungunya fever and zika virus infections in Maranhao State, Brazil

Dengue fever, chikungunya fever, and zika virus infections are increasing public health problems in the world, the last two diseases having recently emerged in Brazil. This ecological study employed spatial analysis of probable cases of dengue fever, chikungunya fever, and zika virus infections reported to the National Mandatory Reporting System (SINAN) in Maranhao State from 2015 to 2016. The software GeoDa version 1.10 was used for calculating global and local Moran indices. The global Moran index identified a significant autocorrelation of incidence rates of dengue (I=0.10; p=0.009) and zika (I=0.07; p=0.03). The study found a positive spatial correlation between dengue and the population density (I=0.31; p<0.001) and a negative correlation with the Performance Index of Unified Health System (PIUHS) by basic care coverage (I=-0.08; p=0.01). Regarding chikungunya fever, there were positive spatial correlations with the population density (I=0.06; p=0.03) and the Municipal Human Development Index (MHDI) (I=0.10; p=0.002), and a negative correlation with the Gini index (I=-0.01; p<0.001) and the PIUHS by basic care coverage (I=-0.18; p<0.001). Lastly, we found positive spatial correlations between Zika virus infections and the population density (I=0.13; p=0.005) and the MHDI (I=0.12; p<0.001), as well as a negative correlation with the Gini index (I=-0.11; p<0.001) and the PIUHS by basic care coverage (I=-0.05; p=0.03). Our results suggest that several socio-demographic factors influenced the occurrence of dengue fever, chikungunya fever, and zika virus infections in Maranhao State

Síndrome de Torsades de Pointes: análise de casos: Torsades de Pointes Syndrome: case analysis

A Síndrome de Torsades de Pointes (TdP) é uma taquiarritmia ventricular polimórfica de pacientes com um intervalo QT longo congênito ou induzido por fármacos, cujo eletrocardiograma possui aspecto de “torção das pontas” e os sinais e sintomas característicos são síncope, palpitação ou mesmo evolução para fibrilação ventricular e morte súbita. O sexo mais frequentemente acometido é o feminino, o diagnóstico se baseia no eletrocardiograma e o tratamento preconizado é o sulfato de magnésio (MgSO4) intravenoso, a correção dos distúrbios eletrolíticos, principalmente a hipocalemia e o tratamento da causa base, na TdP farmacoinduzida. O objetivo do estudo é analisar os casos de Síndrome de Torsades de Pointes em pacientes com alterações do intervalo QT no eletrocardiograma. Trata-se de uma revisão bibliográfica integrativa, do tipo quantitativa, que utilizou as plataformas do PubMed, SciELO e Cochrane Library como bases de dados para seleção dos artigos, todos na língua inglesa. Foram utilizadas literaturas publicadas com recorte temporal de 2017 a 2022. De acordo com as literaturas analisadas, conclui-se que a TdP é uma taquiarritmia ventricular polimórfica com um mau prognóstico se não tratada precocemente com o MgSO4 intravenoso e, por ter diversas etiologias, é primordial que o diagnóstico preciso seja estabelecido de forma rápida, devido ao alto índice de mortalidade. Pacientes portadores da síndrome do QT longo congênita, bradicardia sinusal e bloqueio atrioventricular de 1º grau possuem predisposição para o desenvolvimento de TdP. Observa-se escassez na literatura a respeito das formas adequadas de prevenção da TdP, já que muitos pacientes que participam das triagens, muitas das vezes inefetivas, adquirem a síndrome após o uso de drogas que a predispõem, com prolongamento do intervalo QT, ou não sabem que possuem uma SQTL pré-existente, obrigatória para o desenvolvimento da TdP

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
