    Aim: To systematically review the literature on the effectiveness of the computerized method of dental anesthesia in relation to pain, non-collaborative behavior and fear/anxiety in children and adolescents compared to the conventional method. Materials and methods: An electronic search was performed in five databases (Virtual Health Library, Scopus, Embase, Pubmed and Web of Science) that included randomized clinical trials. The search was performed in October 2020 and updated in May 2021. The risk of bias assessment was performed using the RoB 2 and a qualitative analysis was also performed. Results: A total of 3,518 studies were found, and after removing duplicates, analyzing the title and abstract, and complete reading, 26 studies remained included. Of these, five assessed anxiety/fear, twelve assessed behavior during anesthesia, and twenty-two assessed pain perception. No significant difference was observed in most studies between the use of the computerized method compared to the traditional method for all outcomes analyzed. Discussion: Although there does not seem to be a significant difference in pain perception, fear/anxiety reports and behavior between the use of the computerized method and the traditional method, it is fundamental to evaluate the child's behavior during dental care, as their expressions may indicate some discomfort and pain. These findings should be interpreted with caution, considering that nearly three-quarters of the included studies were at high risk of bias. Conclusion: Even with the absence of difference, electronic devices are promising, as they promote slow and controlled administration and result in safe and effective anesthesia, which is an alternative to clinical practice.Objetivo: Revisar sistematicamente a literatura sobre a efetividade do método computadorizado de anestesia odontológica em relação à dor, comportamento não colaborador e o medo/ansiedade em crianças e adolescentes em comparação com o método convencional. Materiais e métodos: Uma busca eletrônica foi realizada em cinco base de dados (Biblioteca Virtual em Saúde, Scopus, Embase, Pubmed e Web of Science) e que incluiu ensaios clínicos randomizados. A busca foi realizada em outubro de 2020 e atualizada em maio de 2021 e, não houve restrição de data ou idioma. A avaliação de risco de viés foi realizada usando a RoB 2 e, também foi realizada uma análise qualitativa. Resultados: Foram encontrados 3.518 estudos, e após a remoção das duplicatas, análise do título e resumo e, leitura completa, restaram 26 estudos incluídos. Destes, cinco avaliaram ansiedade/medo, doze avaliaram o comportamento durante a anestesia, e vinte e dois avaliaram a percepção de dor. Não foi observado diferença significativa na maioria dos estudos entre o uso do método computadorizado em comparação ao método tradicional para todos os desfechos analisados. Discussão: Apesar de não parecer haver diferença significativa na percepção de dor, no relato de medo/ansiedade e no comportamento entre o uso do método computadorizado em comparação ao método tradicional, é fundamental avaliar o comportamento da criança durante o atendimento odontológico pois suas expressões podem indicar algum desconforto e dor. Esses achados devem ser interpretados com cautela, considerando que quase três quartos dos estudos incluídos apresentaram alto risco de viés. Conclusão: Mesmo com a ausência de diferença, os dispositivos eletrônicos são promissores, visto que promovem uma administração lenta e controlada e resultam em uma anestesia segura e eficaz que coloca-se como alternativa a prática clínica

    Objective: To analyze the associated factors of reductions for dental visits performed in Primary Health Care (PHC) in Brazil during COVID-19 pandemic. Methods: Crosssectional study with PHC dentists. The outcome was a reduction in dental care appointments and that the exposure variables included sociodemographic factors, aspects about personal protective clothing and equipment (PPE) and measures adopted by the Basic Health Unit (UBS) in Brazil after the appearance of COVID. Poisson regression was performed, used to determine the prevalence ratio and 95% confidence interval. Results: Reduction in visits above 50% after the onset of the pandemic was reported by 62.6% of 958 participating. Biosafety protocols (PR=1.04 – 95%CI 1.01;1.07), PPE suggested by the protocols (PR=0.94 – 95%CI 0.89;0.99), and telescreening (PR=0.90 – 95%CI 0.85;0.96) were factors associated with this reduction. Conclusion: The availability of the new PPE and the implementation of telescreening at UBS seem to have minimized the reduction in dental care after the onset of the pandemicObjetivo: Analizar factores asociados a la reducción de consultas odontológicas en Atención Primaria de Salud (APS) en Brasil durante COVID-19.

    A aderência ao PIIP da UFT através de PIP próprio foi motivado por uma dificuldade do processo de ensino: uma pretensa contradição entre a teorização e a prática do economista. O PIP do Curso aparece como ferramenta de aproximação destas dimensões, importante à motivação dos alunos. Estrutura-se em três ambientes: um para oferta de grupos de estudos, mini-cursos, oficinas, seminários, palestras, etc., outro para ofertas de monitoria aos estudantes; e um terceiro, para convívio entre estudantes por meio de projetos recreativos e culturais. Os espaços para ações no âmbito destas atividades foram estruturados neste exercício, e importantes ações foram ofertadas. Mas o projeto, pela novidade que representa, precisa ainda de importantes aprimoramentos

    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

    ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

    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.

    Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

    The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
