Fatores associados ao atraso do desenvolvimento motor de crianças prematuras internadas em unidade de neonatologia

OBJETIVOS: verificar a frequência do atraso do desenvolvimento motor em crianças prematuras internadas em unidade neonatal e identificar os fatores associados. MÉTODOS: estudo descritivo e analítico, realizado na Unidade Neonatal de uma maternidade de alto risco em Recife, Brasil. Avaliou-se o desenvolvimento motor, através do Test of Infant Motor Performance, de 98 crianças nascidas pré-termo com idade pós-conceptual mínima de 34 semanas, durante a internação, entre janeiro e julho de 2009. Analisaram-se associações entre variáveis maternas, neonatais e assistenciais com desenvolvimento motor. RESULTADOS: a média de idade pós-conceptual na avaliação foi de 37 semanas e 39,8% das crianças apresentaram desenvolvimento motor alterado (atípico ou suspeito). Fatores significativamente associados ao desenvolvimento motor alterado foram: menor peso ao nascer; maior idade na avaliação; maior número de consultas pré-natais; ocorrência de hipóxia e displasia broncopulmonar; maior tempo de permanência na unidade de terapia intensiva e unidade neonatal. Houve tendência significante a um pior desenvolvimento motor com uso de oxigenoterapia e ventilação mecânica prolongadas. CONCLUSÕES: crianças prematuras internadas podem apresentar atraso precoce do desenvolvimento motor, de forma grave ou limítrofe. Peso ao nascer, morbidades neonatais e assistência recebida na unidade neonatal foram os fatores que mais influenciaram o desfecho. Esses resultados justificam o início de estratégias preventivas e estimulação ainda no período de internação

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
