    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Get PDF
    Introduction: Tetralogy of Fallot involves four specific heart problems. Firstly, there is pulmonary stenosis, characterized by the narrowing of the pathway that carries blood from the heart to the lungs, hindering blood flow. Right ventricular hypertrophy is another characteristic, where the muscle of the right ventricle of the heart becomes thicker due to increased workload caused by pulmonary stenosis. Methodology: The present study adopted a descriptive epidemiological approach with the aim of analyzing cases of Tetralogy of Fallot among live births in Brazil from 2012 to 2021. Data collection utilized the Live Birth Information System (SINASC), made available by DATASUS. Results: In the group of individuals born with Tetralogy of Fallot, the analysis of variables reveals valuable information about demographic characteristics and perinatal conditions. Regarding the "Race/Ethnicity" variable, out of the 943 cases registered, 588 (62.35%) were classified as white, 51 (5.41%) as black, 10 (1.06%) as yellow, 267 (28.31%) as brown, and 27 (2.86%) had race/ethnicity recorded as unknown. Conclusion: A profound understanding of congenital heart diseases not only saves lives but also significantly improves the quality of life for affected individuals.Introdução: A Tetralogia de Fallot envolve quatro problemas cardíacos específicos. Em primeiro lugar, há a estenose pulmonar, caracterizada pelo estreitamento da via que conduz o sangue do coração para os pulmões, dificultando o fluxo sanguíneo. A hipertrofia ventricular direita é outra característica, onde o músculo do ventrículo direito do coração torna-se mais espesso devido ao aumento da carga de trabalho provocado pela estenose pulmonar. Metodologia: O presente estudo adotou uma abordagem epidemiológica descritiva com o objetivo de analisar os casos de Tetralogia de Fallot entre os nascidos vivos no Brasil no período de 2012 a 2021. Para a coleta de dados, utilizou-se o Sistema de Informações sobre Nascidos Vivos (SINASC), disponibilizado pelo DATASUS Resultado: No grupo de nascidos com Tetralogia de Fallot, a análise das variáveis revela informações valiosas sobre características demográficas e condições perinatais. Em relação à variável "Cor/Raça", dos 943 casos registrados, 588 (62,35%) eram classificados como brancos, 51 (5,41%) como pretos, 10 (1,06%) como amarelos, 267 (28,31%) como pardos, e 27 (2,86%) tiveram a cor/raça registrada como ignorada Conclusão: A compreensão profunda das cardiopatias congênitas não apenas salva vidas, mas também melhora significativamente a qualidade de vida dos indivíduos afetados

    Síndrome de Chiari e Hidrossiringomielia com comprometimento neurológico: um relato de caso

    Get PDF
    A Malformação de Chiari (MC) pertence a um amplo grupo de raras deformidades estruturais da junção craniocerebelomedular. O tipo I da doença caracteriza-se pela herniação tonsilar ou amigdaliana cerebelar devido à anomalia da base do crânio e da parte superior da coluna cervical, além de a porção medial do lobo inferior do cerebelo pelo canal cervical também se protuberar através do forame magno, impedindo que o líquor flua normalmente através do canal. A real prevalência da doença é desconhecida, pois muitos pacientes com herniação cerebelar são assintomáticos e o problema agrava-se na fase adulta, com queixas de cefaleia intensa e, por vezes, parestesia. O objetivo deste estudo é relatar um caso de síndrome de Chiari (SC) em uma paciente de 53 anos, ao abordar sua apresentação clínica, diagnóstico e tratamento. Paciente do sexo feminino, 53 anos, foi admitida em um hospital da rede pública de referência se queixando de cefaleia occipital intensa e cervicalgia com irradiação da dor para os membros superiores, acompanhada de parestesia nos quatro segmentos. Relatou já sentir dor há 2 anos, mas apresentou piora do quadro clínico há 8 meses. Foi, também, observada incontinência urinária devido à dissinergia detrusora-esfincteriana por provável bexiga neurogênica. Foi, então, realizado exame de imagem de ressonância magnética (RNM) do crânio e da coluna cervical, com obtenção de sequências ponderadas em T1, T2 e STIR, nos planos sagital e transverso com contraste, o qual evidenciou leve alargamento medular, além de sinais de hidrossiringomielia difusa, com hipossinal na sequência T2 intramedular na altura de D1-D2 (coluna dorsal). Foi notada discreta herniação das tonsilas cerebelares junta ao forame magno, típica da SC, sendo, por fim, confirmado o diagnóstico. A paciente, no entanto, não apresentava hidrocefalia, mesmo com a interrupção do fluxo do líquido cefalorraquidiano (LCR) para o canal vertebral. Ela encaixou- se nos parâmetros de indicação cirúrgica, sendo realizada craniotomia occipital, com acesso ao plexo coroide do quarto ventrículo do tronco encefálico com o intuito de elevar as tonsilas cerebelares baixas, herniadas no canal espinhal cervical e bloqueando o fluxo do LCR. Após a descompressão craniocervical, o curso do líquor foi restaurado e a paciente foi, por fim, encaminhada à sala de recuperação pós-operatória. A SC é uma rara doença que apresenta quadro clínico e alterações radiológicas complexas e extensas e, por vezes, o diagnóstico é retardado devido à inespecificidade dos sintomas confundidos com cervicalgias e cefaleias comuns. A hipótese diagnóstica deve ser embasada nas queixas do paciente, na anamnese minuciosa, exame clínico e nos exames de imagens, sendo a prevalência desta patologia de difícil definição e com faixas etárias distintas

    Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
