Fatores associados à qualidade de vida dos profissionais-docentes e seus impactos socio-pessoal-laborais / Factors associated with the quality of life of professionals-teachers and their social-personal-laboral impacts

Objetivo: Entender os fatores associados à qualidade de vida dos docentes e seus impactos sociais, pessoais e laborais. Método: Foi realizada uma revisão de literatura com estudos no período de 2015/2019, a partir dos descritores “Qualidade de vida, Medicina do Trabalho, Doenças ocupacionais, Condições de Trabalho, Medicina Ocupacional, Docentes”. Resultados: A partir da análise dos artigos foi possível observar que docentes sofrem frequentemente com manifestações psíquicas e físicas. Os estudos reforçam que a qualidade de vida dos profissionais está associada, sobretudo, a fatores como dores músculoesqueléticas, distúrbios psiquiátricos menores, precarização do ambiente do trabalho e baixa qualidade do sono. Conclusão: É necessário, portanto, realizar mais Pesquisas no que se refere à qualidade de vida dos profissionais. O seu feito pode gerar resoluções que diminuam os impactos gerados pela baixa qualidade de vida dos docentes, repercutindo positivamente na sua vivência

Rotavirus and the emergence of new genotypes: a narrative review

Rotavirus infection, which is directly related to the population’s quality of life, can culminate in death, mainly of children. This review discusses the prevalence and distribution of rotavirus genotypes, focusing on the genotypic variation of the virus after the implementation of vaccines and the cross-infection between animal and human species. It was searched the published literature from January 2006 to July 2017 using the Web of Knowledge database and the search terms “rotavirus”, “genotype”, “prevalence post vaccine”, and “emerging genotypes”. It was observed that the predominant genotypes changed in all continents, and that some genotypes are still emerging. Two hypotheses for this global change are the genetic variability of the virus and the emergence of vaccine-resistant genotypes. In addition, the virus can easily infect several animal species other than humans, as evidenced by reports of cross-infection of strains, which have served as warning for the generation of new virus genotypes. Inter-sectoral actions that encompass not only the health sector, but also all the socio-economic sector including the government, researchers, teachers, health agents, and communities contribute to decrease health-related expenditures and reduce mortality caused by the rotavirus, thereby improving health indicators and promoting health around the world.Rotavirus infection, which is directly related to the population’s quality of life, can culminate in death, mainly of children.

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors

A Genética Médica tornou-se uma especialidade médica reconhecida, com conceitos e abordagens importantes no diagnóstico e tratamento de muitas doenças, comuns e raras. As doenças genéticas seguem padrões de herança, podendo ser autossômicas recessivas, autossômicas dominantes, ligadas ao cromossomo X ou ao cromossomo Y, ou multifatoriais. O objetivo do estudo é padronizar um instrumento de coleta de dados para ser utilizado nos encaminhamentos de  pacientes atendidos no Centro de Especialidades Médicas do ambulatório de Genética Médica de um Centro Universitário de Belém, Pará. Os dados foram coletados a partir de prontuários de pacientes, atendidos entre 2014 e 2019, usando protocolo próprio dos pesquisadores, com dados analisados e tabulados através do programa Microsoft Excel. Foi realizada a análise de 101 prontuários, a partir disso, constatou-se que não existe uma coleta padronizada da história clínica dos pacientes, acarretando na perda de informações importantes. Os resultados do presente estudo revelam a necessidade do preenchimento adequado, respondendo questionamentos pertinentes para elucidação diagnóstica, uma vez que o diagnóstico correto conduz a um tratamento adequado

Study of the requirements of an autonomous system for surface water quality monitoring

In recent years, there has been increasing awareness of the preservation, protection and sustainable use of natural resources. Water resources, being one of the most important natural resources, face major threats due to contamination by pollutants of various types and origins. Maintaining the quality of water resources requires more robust, reliable and more frequent monitoring than traditional techniques of data collection based on sporadic, discontinuous and manual processes. The management of large geographical areas, the insufficient spatiotemporal discretization of the values of samples collected by traditional processes and the unpredictability of natural phenomena, require a new approach to data collection procedures. This article, which is the result of ongoing research, defines the technical requirements and technologies used in a continuous and regular monitoring of surface water quality in freshwater systems, whose data acquisition system helps to identify the sources of pollution and the contaminants flow along the waterways. The design of a versatile real-time water quality monitoring system, which, due to its environmental constraints should be based on renewable energies and wireless transfer of energy, will contribute to improve the management and effective protection of water resources.This work was supported by Centro2020, Portugal 2020 and European Union (EU) under the grants, CENTRO-01-0145-FEDER-024052E – Libélula: Mobile robotic surface water quality monitoring system.info:eu-repo/semantics/publishedVersio

AVALIAÇÃO DA SUSTENTABILIDADE AMBIENTAL DAS SUB-BACIAS DOS RIACHOS SECO E PRECUÁ, NOS MUNICÍPIOS DE BACABEIRA E ROSÁRIO – MA: Bases para o ordenamento territorial

O presente trabalho propõe avaliar a sustentabilidade ambiental das sub-bacias dos Riachos Seco e Precuá, considerando os aspectos físicos, o uso e cobertura do solo, o desenvolvimento humano, o índice de sustentabilidade ambiental e as áreas de conflito de uso. As sub-bacias dos Riachos Seco e Precuá estão sofrendo uma intensa modificação na sua estrutura e funções ecossistêmicas, devido às atividades operacionais para a implantação da Refinaria Premium I nos municípios de Bacabeira e Rosário, impondo a necessidade do estabelecimento de indicadores quantitativos que reflitam as mudanças ambientais nos corpos d’água investigados. Os indicadores adotados no estudo refletem os aspectos propostos no modelo de avaliação PEI/ER (pressão-estado-impacto/efeito resposta), o qual foi recomendado pela Organização para a Cooperação Econômica e Desenvolvimento - OECD. As sub-bacias do Riacho Seco e Precuá pertencem à bacia hidrográfica do rio Itapecuru, estando situadas em seu curso inferior, entre os limites dos municípios de Bacabeira e Rosário. Os recursos ambientais foram identificados a partir do uso de imagens de satélite LANDSAT 5 dos anos de 2000 e 2010. As imagens de satélite possibilitaram a determinação da evolução do uso e cobertura do solo, na geração do fator de proteção solo e auxiliou na identificação das áreas de conflito de uso, entre os anos de 2000 e 2010. Para caracterizar a população, utilizaram-se dados demográficos do Censo 2000 e de 2010, tomando como base a agregação de setores censitários. Os resultados obtidos mostraram que a sub-bacia do Riacho Precuá apresentou menor redução no grau de proteção existente, decorrente de um maior incremento nas atividades impactantes do solo. Apesar destas intervenções, o índice de sustentabilidade indicou que as sub-bacias analisadas apresentam um grau de integridade consistente. 

Analysis of active chlorine releasing and pH of sodium hypochlorite solutions used in Endodontics

The use of a suitable irrigation solution and a correct root system shape effectively contributes to the success of endodontic treatment. Among the irrigating solutions used in Endodontics, sodium hypochlorite has been the most used because of many qualities. However, this substance must have chemical stability of its properties, by maintaining the potential of hydrogen (pH) and chlorine concentrations appropriately. Objective: The aim of this study was to evaluate active chlorine releasing and pH of some sodium hypochlorite solutions used in endodontic clinical practice. Material and methods: The solutions tested in this study were 0.5% Dakin, 1% Milton, 2% Chlorinated Soda, and household bleaches (Brilux®and Qboa®), which were opened at the same period and first used, with the same storage modus but with different manufacturing dates. The pH was measured with a digital device, and the active chlorine content was obtained through iodometric titration. Results:All solutions presented chlorine content not smaller than that informed in the flasks, ranging from 1% to 2.4%; pH was higher in all solutions, between 9 and 13. Conclusion: Based on the method applied and the results obtained, it was possible to conclude that sodium hypochlorite solutions used specifically in Dentistry (Dakin and Milton solutions and Chlorinated Soda), showed on the labels the hypochlorite content. On the other hand, household bleaches (Brilux® and Qboa®) showed the chlorine content. It was not possible to compare pH authenticity, due to lack of description on the label

Antibacterial and Cytotoxic Activities of Pinus tropicalis and Pinus elliottii Resins and of the Diterpene Dehydroabietic Acid Against Bacteria That Cause Dental Caries

Considering the impact of dental caries on public health and the wide biological potential described for species belonging to the genus Pinus, here we investigate the antibacterial activity of the P. elliottii and P. tropicalis resins and of the diterpene dehydroabietic acid (DHA) against cariogenic bacteria. For this purpose, we have determined the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of the resins and of the diterpene. We have also investigated the biofilm inhibition ability (through MBIC50 determination), as well as the synergistic effect (through fractional inhibitory concentration index) and the cytotoxic potential (through XTT assay) of the P. elliottii and P. tropicalis resins. The resins gave promising MIC and MBC values, which ranged from 12.5 to 400 μg/mL; DHA provided MIC and MBC values ranging from 25 to 400 μg/mL. The MICB50 values ranged from 0.78 to 400 μg/mL for the resins. Neither additive nor synergistic effects emerged for the combinations of one of the resins with chlorhexidine. The cytotoxic activity was ≥312.5 and ≥156.3 μg/mL for the P. elliottii and P. tropicalis resins, respectively. The resins showed antibacterial activity against planktonic and sessile cariogenic bacteria. These data are relevant and encourage further research into these plants, which may contribute to the discovery of new substances that can inhibit the growth of cariogenic microorganisms and reduce the incidence of dental caries

Supramolecular Materials for Optical and Electrochemical Biosensors

It is incontestable that the interactions and bonds that keep molecules united to generate unique supramolecular compounds, with individual properties, morphologies and behaviour, are of special dynamics and singular forces. Therefore, it is necessary to discuss and consider the types of interactions that may occur in a determined system, their dynamics and number, which directly act on the energetic balance that strengthen the union between participants and give rise to a supramolecule
