LIDERANÇA E PARTICIPAÇÃO: O FOCO NO PROTAGONISMO JUVENIL EM UMA ESCOLA TÉCNICA ESTADUAL

Este artigo tem como objetivo, compreender a formação da autonomia e participação efetiva dos jovens no contexto escolar, através do protagonismo juvenil. Ele provém de uma pesquisa de mestrado que se dedicou a investigar o cotidiano da gestão escolar em uma Escola Técnica Estadual, do município de Bezerros, no agreste de Pernambuco, integrante do Programa de Educação Integral. A fundamentação teórica baseou-se nas concepções apresentadas por estudiosos consagrados sobre temáticas como: gestão escolar, gestão democrática, participação, liderança, protagonismo juvenil e Educação Interdimensional, sendo esta última, arcabouço filosófico das Escolas Técnicas Estaduais e Escolas de Referência em Ensino Médio de Pernambuco. O itinerário investigativo desta pesquisa se deu através da pesquisa-ação e constituição de um grupo focal formado por educandos e coordenadores. Desta maneira, foi possível mergulhar na realidade vivida pelos sujeitos, de onde foram coletados os dados e informações relevantes para a pesquisa, fazendo ainda uso de questionários e entrevistas semiestruturadas. Percebeu-se que as ações de promoção do protagonismo e da participação, podem ser instrumentos para a formação de jovens líderes na sociedade civil

Objetivo: Identificar as experiências dos enfermeiros na prática da Sistematização da Assistência de Enfermagem (SAE) na Unidade de Terapia Intensiva (UTI). Métodos: Tratou-se de um estudo descritivo-exploratório com abordagem qualitativa através de pesquisa de campo, tendo como cenário um hospital privado localizado no município de Niterói/RJ, sendo os sujeitos são 10 enfermeiros que atuam no setor. Resultados: Os depoimentos sofreram análise temática, onde surgiram os seguintes núcleos de sentido: os fatores que interferem na implementação da SAE na UTI e o (des) conhecimento do enfermeiro sobre a SAE. Conclusão: Pôde-se compreender que a SAE e sua implementação na UTI perpassa por meandros que interagem diretamente com as tecnologias do cuidado de enfermagem. Cumpre-se expressar que o enfermeiro deve ser visto como primeiro cliente, ou seja, necessita de valorização profissional com respeito a sua individualidade, assim proporcionará à clientela um desvelo integral baseado na motivação de implementar a SAE.&nbsp

Reflecting on the practice of nursing care systematization in the intensive care unit

Objective: To identify the experiences of nurses in the practice of nursing care systematization in the intensive care unit (ICU). Method: This was a descriptive and expIoratory study with a qualitative approach through field research. It was a private hospital located in Niterói, in a municipality of Rio de Janeiro City. The participants are 10 nurses who work in the sector of intensive care. Results: The statements suffered thematic analysis where emerged the following classes: Factors affecting the implementation of the SAE in the ICU and (un) knowable of nurses about the CNS. Conclusion: It might be understood that the NSQ and its implementation in the ICU run through intricacies that interact directly with the nursing care technologies. We should express that the nurse should be seen as the first customer, in other words, requires professional valuation with respect to his individuality, so he will provide to the customers a full commitment based on motivation to implement the CN

Cytotoxicity assessment of endodontic sealers: metabolic activity, morphology and chromosomal alterations

Introduction: Endodontic treatment aims to eliminate infection of the root canals and fill the dental pulp space, being, the obturation of root canals an important step. The study of the toxicity/biocompatibility of the sealers used to fill the root canals is crucial since they are applied into direct contact with periradicular tissues.There are several types of sealers, categorized according to their main chemical constituents. The aim of this study was to evaluate the cytotoxicity of three root canal sealers, AH Plus, Bio MTA+ and Bio C, on immortalized human gingival fibroblasts. Methods: To study the cytotoxicity of the sealers we performed a Methyltetrazolium (MTT) assay, a study of cell's morphology and a cytogenetic study. Cells were placed in contact with material-conditioned media, for 24 h, at three different concentrations (1, 10 and 100 mg/ml) for the MTT assay. Cell morphology and cytogenetic studies were performed at 100 mg/ml. Cells in normal culture medium were analyzed as control group. Results: MTT assay revealed a cytotoxic effect of Bio MTA+ and Bio C with a growing decrease of metabolic activity with increasing compound concentration, reaching 50% with 100 mg/ml. Regarding the cells morphology, Bio C was the compound that showed a more drastic effect, with a decrease in cell confluence and several morphological changes. AH Plus and Bio MTA+ did not seem to affect the cell confluence, however morphology changes were observed, as compromised cell membranes and loss of cell content. Cytogenetic study was thus far only performed with AH Plus. Since there was a severe decrease of mitotic index after treatment, it was not yet possible to obtain sufficient metaphases, even after several cytogenetic harvesting procedures, but, so far, no relevant structural or numerical changes were observed. Discussion: This preliminary study allowed us to verify that these root canal sealers exhibit some cytotoxicity, depending on the concentration used. Although more studies are still needed, this work could be important to both, help in the selection of the most appropriate compounds for clinical practice and to determine the maximum recommended amounts of each sealer.info:eu-repo/semantics/publishedVersio

Evaluation of the properties of WHODAS-12 measurements in individuals with Chagas disease in Brazil

Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser–Meyer–Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD

A comprehensive assessment of the transcriptome of cork oak (Quercus suber) through EST sequencing

Background: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic information. Cork oak forests are of great ecological importance and represent a major economic and social resource in Southern Europe and Northern Africa. However, global warming is threatening the cork oak forests by imposing thermal, hydric and many types of novel biotic stresses. Despite the economic and social value of the Q. suber species, few genomic resources have been developed, useful for biotechnological applications and improved forest management. Results: We generated in excess of 7 million sequence reads, by pyrosequencing 21 normalized cDNA libraries derived from multiple Q. suber tissues and organs, developmental stages and physiological conditions. We deployed a stringent sequence processing and assembly pipeline that resulted in the identification of ~159,000 unigenes. These were annotated according to their similarity to known plant genes, to known Interpro domains, GO classes and E.C. numbers. The phylogenetic extent of this ESTs set was investigated, and we found that cork oak revealed a significant new gene space that is not covered by other model species or EST sequencing projects. The raw data, as well as the full annotated assembly, are now available to the community in a dedicated web portal at http://www.corkoakdb.org. Conclusions: This genomic resource represents the first trancriptome study in a cork producing species. It can be explored to develop new tools and approaches to understand stress responses and developmental processes in forest trees, as well as the molecular cascades underlying cork differentiation and disease response.Peer Reviewe

Pervasive gaps in Amazonian ecological research

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
