    Este trabalho teve como objetivo o desenvolvimento de um mapeamento sistemático com a finalidade de identificar as principais abordagens de mensuração de características de autorregulação da aprendizagem em ambientes online. A identificação destas abordagens fornecem subsídios para identificar as principais formas de análises e coletas que estão sendo utilizadas na literatura. Os resultados mostram que ainda é pouca expressiva a quantidade de trabalhos que utilizam dados comportamentais, através de logs, para a mensuração em tempo real. Este parece ser um tema desafiador especialmente considerando o número cada vez maior de cursos a distância, número de alunos e volume de dados gerados em plataformas de aprendizagem online

    Get PDF
    Introdução: Pacientes hepatopatas, geralmente, apresentam um quadro clínico grave que pode se intensificar rapidamente fazendo com que a espera até o transplante de fígado ou o pós-cirúrgico tenha má prognósticos. Com isso, a oxigenoterapia hiperbárica é descrita em alguns estudos como uma alternativa nesses casos por mitigar os efeitos das doenças e do transplante hepático. Objetivo: Descrever os efeitos da oxigenoterapia hiperbárica no pré e no pós-operatório de pacientes submetidos ao transplante hepático. Métodos: Trata-se de uma Revisão Integrativa na base de dados PubMed e Web Of Science. Foi utilizado os descritores: “Hyperbaric oxygenation”, “Liver transplantation” e “Hyperbaric oxygen therapy” com o operador booleano “AND”, e selecionados artigos de relevância para o tema. Inicialmente, foram selecionados 49 artigos, todos publicados nos últimos 20 anos, em português e/ou inglês. Após análise, 6 artigos corresponderam ao objetivo proposto. Resultados: Pode-se verificar que o conteúdo intraoperatório de O2 sistêmico afeta a recuperação pós-operatória em pacientes submetidos ao transplante de fígado. A oxigenoterapia hiperbárica precoce atua como protetor na redução da gravidade da lesão de isquemia/reperfusão dos hepatócitos. A oxigenoterapia hiperbárica também influencia na resposta imune do paciente submetido ao transplante de fígado, reduzindo a incompatibilidade. Ainda sobre os efeitos imunomodulatórios da oxigenoterapia hiperbárica, essa terapia se mostrou eficaz no auxílio da prevenção de infecções pós-operatórias por melhorar a atividade antibacteriana das células imunes e aumentar o efeito bactericida dos antibióticos. Tratando-se de pacientes em lista de espera para transplante de fígado, foi observado após tratamento com a oxigenoterapia a diminuição no número e na intensidade dos episódios de encefalopatia, melhora do prurido e sentimento de bem-estar. No quesito disfunção precoce do aloenxerto, foi demonstrado que pacientes com disfunção apresentaram valores mais baixos de O2 nas fases anepática e neo-hepática, quando comparado com os pacientes sem disfunção no período pósoperatório. Além disso, durante a fase anepática, o conteúdo do nível de SatO2 também foi menor no grupo com disfunção do que nos sem disfunção. Conclusão: A oxigenoterapia hiperbárica é benéfica na preservação do fígado, uma vez que ajuda a manter a função hepática, a prolongar o tempo de preservação do fígado e melhorar o resultado do transplante hepático

    Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

    Get PDF
    Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

    NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

    No full text
    Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.

    The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

    NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

    No full text
    Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
