Estimulaçao ventricular mínima associada à estimulaçao na via de saída do ventrículo direito: análise do remodelamento atrial elétrico e mecânico atrial e da qualidade de vida

Introduçao: O algoritmo de estimulaçao ventricular mínima (EVM) do marcapasso (MP) de dupla-câmara permite uma estimulaçao cardíaca fisiológica. Questiona-se se a associaçao a um sítio alternativo de estimulaçao ventricular pode reduzir a incidência de arritmias supraventriculares em longo prazo, sobretudo a fibrilaçao atrial (FA) crônica. Objetivo: Comparar a densidade de arritmia atrial, a dimensao do átrio esquerdo e a qualidade de vida quando do sinergismo entre a EVM (por meio d

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

Educomunicação e suas áreas de intervenção: Novos paradigmas para o diálogo intercultural

oai:omp.abpeducom.org.br:publicationFormat/1O material aqui divulgado representa, em essência, a contribuição do VII Encontro Brasileiro de Educomunicação ao V Global MIL Week, da UNESCO, ocorrido na ECA/USP, entre 3 e 5 de novembro de 2016. Estamos diante de um conjunto de 104 papers executivos, com uma média de entre 7 e 10 páginas, cada um. Com este rico e abundante material, chegamos ao sétimo e-book publicado pela ABPEducom, em seus seis primeiros anos de existência. A especificidade desta obra é a de trazer as “Áreas de Intervenção” do campo da Educomunicação, colocando-as a serviço de uma meta essencial ao agir educomunicativo: o diálogo intercultural, trabalhado na linha do tema geral do evento internacional: Media and Information Literacy: New Paradigms for Intercultural Dialogue

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 understanding 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,5,6,7 vast areas of the tropics remain understudied.8,9,10,11 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 underrepresented in biodiversity databases.13,14,15 To worsen this situation, human-induced modifications16,17 may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities 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 organism 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 neglected 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 lost

Production of nanocomposite films functionalized with silver nanoparticles bioreduced with rosemary (Rosmarinus officinalis L.) essential oil

This study produced nanocomposite films with silver nanoparticles (AgNPs) bioreduced with rosemary (Rosmarinus officinalis L.) essential oil. The nanocomposites were produced by the casting technique with gelatin/carboxymethyl cellulose/citric pectin and functionalized with 15, 30, and 50% (v/v) AgNPs. The results demonstrate that the rosemary essential oil presented various bioactive compounds, and the major compounds were α-pinene, bornyl acetate, and 1,8-cineol. The AgNPs showed a particle size lower than 50 nm, zeta potential of −30 mV, and polydispersity index of 0.35. UV–vis spectroscopy, TEM, SEM, and XRD confirmed the synthesis of AgNPs with spherical shapes, diameters of 50 nm, and crystalline structures. The nanocomposite films containing AgNPs demonstrated strong antimicrobial activity against eight pathogenic microorganisms. The incorporation of AgNPs affected the opacity and improved the mechanical properties of the nanocomposites. In conclusion, the eco-friendly nanocomposite produced can be a sustainable material for biological applications

Obesidade e fatores de risco para o desenvolvimento de doenças crônicas não transmissíveis entre usuários de unidade de alimentação e nutrição Obesity and risk factors for the development of chronic non-transmissible diseases among consumers in a foodservice unit

O objetivo deste estudo foi avaliar o estado nutricional e fatores de risco para doenças crônicas não transmissíveis entre 1.252 funcionários de uma indústria em Santa Catarina, Brasil. Foram estudadas as variáveis: estado nutricional, circunferência da cintura, pressão arterial, glicemia, idade e escolaridade. Observou-se sobrepeso e obesidade em 45% e 10% da amostra, respectivamente, com associação significativa entre o estado nutricional e sexo, mas não entre estado nutricional e escolaridade, ajustados por idade. Verificaram-se valores de circunferência da cintura elevados em 33% dos funcionários, com diferença significativa entre sexos. Observou-se pressão arterial sistólica (PAS) e pressão arterial diastólica (PAD) elevadas em 18% e 11% dos funcionários, respectivamente, com associação significativa entre sexos após ajuste por idade. Diagnosticou-se diabetes mellitus tipo II em 2% da amostra e glicemia alterada em 4%. Após ajuste por idade, as únicas variáveis associadas à circunferência da cintura foram a PAS e a PAD. Estes resultados permitiram que atividades preventivas e educacionais fossem desenvolvidas pela empresa, de modo a melhorar a qualidade de vida e a produtividade dos funcionários.<br>This study aimed to assess nutritional status and risk factors for chronic non-transmissible diseases in 1,252 factory employees in Santa Catarina State, Brazil. The following variables were studied: nutritional status, waist circumference, blood pressure, blood glucose levels, age, and schooling. Overweight and obesity were observed in 45% and 10% of the sample, respectively, with a significant association between nutritional status and gender, but not between nutritional status and schooling, adjusted for age. The proportion of high waist circumference was 33%, with a significant difference between genders. High systolic blood pressure (SBP) and diastolic blood pressure (DBP) were present in 18% and 11% of the employees, respectively, with a significant association between genders after adjusting for age. Type II diabetes mellitus was diagnosed in 2% of the sample and altered glucose levels in 4%. After adjusting for age, the only variables significantly associated with waist circumference were SBP and DPB. The results allowed the implementation of preventive and educational activities to improve employees' quality of life and productivity
