Associação entre a deficiência em magnésio e a doença do coronavírus (covid-19): uma revisão integrativa / Association between magnesium deficiency and coronavirus disease (covid-19): an integrative review

A doença do coronavírus (COVID-19) foi caracterizada como pandemia pela Organização Mundial da Saúde (OMS), sendo que milhões de pessoas no mundo foram infectadas pelo novo coronavírus SARS-COV-2. Alguns estudos já têm sido conduzidos com o intuito de verificar a existência de relação entre as concentrações biológicas de minerais, como o magnésio, e a COVID-19, considerando as funções exercidas por esse nutriente, em particular, no fortalecimento do sistema imune. O presente estudo consiste em revisão integrativa conduzida com o objetivo de avaliar a existência de associação entre a deficiência em magnésio e a COVID-19. Uma pesquisa em bases de dados Pubmed, Cochrane Library e ScienceDirect foi feita por dois pesquisadores, sendo incluídos estudos observacionais, experimentais e de intervenção (considerando tempo 0). Foram excluídos da pesquisa alguns tipos de estudo como, exemplo àqueles feitos em animais e revisões. Dos sete estudos incluídos nesta revisão, quatro mostraram, em seus resultados, prevalência elevada de hipomagnesemia nos pacientes com COVID-19, variando de 20,8% a 48%. Além disso, pacientes com COVID-19 internados na UTI apresentaram maior prevalência de hipomagnesemia quando comparados com àqueles que não precisaram de UTI. Dessa forma, os resultados do presente estudo sugerem a existência de associação entre a hipomagnesemia e a COVID-19, bem como com maior gravidade da doença.

Nutritional education through recreational activities as an entertainment tool in Hotel businesses

Food, with its different flavors, is introduced into a child’s life by the family and through nutritional education. Recreational activities also give children the ability to understand what to eat, and how to eat it. Due to the high demand for tourist accommodation that focuses on the family segment, the tourist trade, particularly hotel business, is hiring more employees in the recreation and leisure sector, in order to assist children and parents who want to enjoy a few hours of carefree leisure and rest. This article aims to show that recreational activities that provide nutritional education can be developed by hotel businesses as a form of children’s entertainment, stimulating creativity, teamwork, imagination, interpersonal relationships, the comfort of parents, along with an improvement in dietary habits. This study involves applied, exploratory, descriptive and bibliographic research, with a quantitative analysis to evaluate the level of children's satisfaction, using a visual 3-point Likert Scale. As an action strategy, we organized lectures with fun activities. We conclude that activities associated with nutritional learning are accepted by children as a means of socialization and entertainment, making them tools for use in accommodation establishments, as a recreational activity aimed at encouraging healthy eating.

Sob a bandeira neoliberal: Exame de propostas para a educação em postagens de candidatos do partido novo no Instagram

The purpose of this article is to examine New Party candidates proposals for the education, based on the discourse analysis of posts published on Instagram. With this, we aim to investigate how these proposals are anchored in relations of knowledge and power, which are linked to neoliberal rationality. For this, the focus of analysis rests on four posts aired on the Instagram profile of Partido Novo candidates. This study follows a descriptive-interpretative approach with qualitative bias. Thus, in order to subsidize the analyzes, we use of Foucault's (2008; 2009; 2010), Dardot and Laval (2016), Laval (2004) ad of Sargentini (2015; 2017). The examination of the proposals makes it possible to identify the implications of neoliberal rationality, based on the prioritization of the market and the private sector, through practices such as the awarding of the “best” students and teachers.El propósito de este artículo consiste en examinar propuestas para la educación de candidatos del partido Novo, a partir del análisis del discurso de publicaciones publicadas en Instagram.

The market of cumaru nuts (Dipteryx odorata) in the State of Pará, Brazil

O presente artigo analisou o mercado de amêndoas de semente de cumaru (Dipteryx odorada (Aubl.) Willd.) no estado do Pará na safra de 2005. As informações secundárias foram obtidas através do Instituto Brasileiro de Geografia e Estatística IBGE e do sistema de informação Aliceweb, do Ministério do Desenvolvimento, Indústria e Comércio Exterior. As informações primárias da cadeia foram obtidas através de entrevistas com os agentes envolvidos na comercialização. Os resultados mostram que atualmente os principais países importadores são o Japão, França, Alemanha e China. Aproximadamente 2.700 famílias estão envolvidas no extrativismo de cumaru em todo os estado. As Margens Brutas foram, respectivamente, 20,0 e 15,0% (paras os dois grupos de atravessadores), 33,3 e 46,7%. Já a Markup foi de 75,0% para os atravessadores, 166,7% para as empresas exportadoras do interior e 233,3% para as empresas atacadistas em Belém. No total o Markup foi de 500,0%. O preço do quilo da amêndoa variou de R$3,00 para os extrativistas até R$ 18,00 para as empresas atacadistas. Também foi possível averiguar que os responsáveis pelo maior acréscimo de preço no produto são as empresas exportadoras, o que gera ganhos desproporcionais ao longo da cadeia.Palavras-chave: Cadeia produtiva; cumaru; extrativismo. AbstractThe market of cumaru nuts (Dipteryx odorata) in the State of Pará, Brazil.

Yes, we can: internships providing leverages in the labour market

Facing unprecedented challenges to deal with the problem of graduate unemployment, Higher Education Institutions (HEIs) are increasingly concerned with the professional insertion of their graduates in the labour market and with the design of institutional mechanisms that facilitate students’ transition from higher education to work. This has been achieved, inter alia, through the creation of study programmes with internships, or several other forms of cooperative education between HEIs and employing institutions. Benefits of internships are extensively reported in the majority of studies dealing with the professional integration of graduates. There is a general consensus that internships can be regarded as an institutional mechanism that facilitates students’ transition from higher education to work. However, there seems to be a gap between the intended results and the actual impact of internships on employability, which needs to be better understood. Moreover, existing research tends to be largely based on the perceptions of the main stakeholders involved – students, HEIs, and employing institutions – rather than on actual post-graduation career outcomes. This paper aims to assess the importance of internships for the employability of graduate students. Three inter-related dimensions are explored. Firstly, the extent to which the introduction of internships in study programmes contributes to the decrease of graduate unemployment rates is analysed. Second, the extent to which the different features of internships, namely those associated with their length and structure, contribute to lower graduate unemployment rates is assessed. Thirdly, the internship approaches, which seem to allow greater job preparedness, namely those related to interns’ supervision entailing close collaboration between universities and employers, are discussed. Our empirical data consists of a unique database comprising 1,168 Portuguese first cycle degrees, with study programmes approved from 2006 to 2009 and published in the Official Gazette. These results are crosschecked with the perspectives of the main stakeholders involved in internships, regarding their motivations; required efforts; and expected outcomes. Empirically, this is based on the content analysis of semi-structured individual interviews to units’ coordinators and also focus groups conducted with the coordinators of study programmes; academic internship supervisors; and former interns

Fibre Reinforced Polymer (FRP) connectors for Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) sandwich panels

Insulated sandwich wall panels are frequently composed of external concrete layers, mechanically connected through metallic connectors, such as trusses. Due to their high thermal conductivity, these connectors generally cause thermal bridges on the building envelope. In view of this problem, an innovative system is proposed where FRP connectors are used together with a thermal insulation layer. Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) wythes are also used to obtain panels that are both technically and economically advantageous. However, to present day there is no experimental data on the mechanical behaviour of the suggested connections. In this research, an experimental study is performed to characterize different types of FRP-SFRSCC connections under pull-out tests. Shear connection behaviour under monotonic loading is evaluated with slip controlled tests. Embedded and adhesively bonded connection solutions between SFRSCC layers and FRP connectors are studied.(undefined

Effect of angiotensin II and losartan on the phagocytic activity of peritoneal macrophages from Balb/C mice

Angiotensin II (AII), a product of rennin-angiotensin system, exerts an important role on the function of immune system cells. In this study, the effect of AII on the phagocytic activity of mouse peritoneal macrophages was assessed. Mice peritoneal macrophages were cultured for 48 h and the influence of different concentrations of AII (10-14 to 10-7 M) and/or losartan, 10-16 to 10-6 M), an AT1 angiotensin receptor antagonist, on phagocytic activity and superoxide anion production was determined. Dimethylthiazoldiphenyltetrazolium bromide reduction and the nucleic acid content were used to assess the cytotoxicity of losartan. A stimulatory effect on phagocytic activity (P < 0.05) was observed with 10-13 M and 10-12 M AII concentrations. The addition of losartan (up to10-14 M) to the cell cultures blocked (P < 0.001) the phagocytosis indicating the involvement of AT1 receptors. In contrast, superoxide anion production was not affected by AII or losartan. The existence of AT1 and AT2 receptors in peritoneal macrophages was demonstrated by immunofluorescence microscopy. These results support the hypothesis that AII receptors can modulate murine macrophage activity and phagocytosis, and suggest that AII may have a therapeutic role as an immunomodulatory agent in modifying the host resistance to infection.16717

Angiotensin II (AII), a product of rennin-angiotensin system, exerts an important role on the function of immune system cells. In this study, the effect of AII on the phagocytic activity of mouse peritoneal macrophages was assessed. Mice peritoneal macrophages were cultured for 48 h and the influence of different concentrations of AII (10(-14) to 10(-7) M) and/or losartan, 10(-16) to 10(-6) M), an AT1 angiotensin receptor antagonist, on phagocytic activity and superoxide anion production was determined. Dimethylthiazoldiphenyltetrazolium bromide reduction and the nucleic acid content were used to assess the cvtotoxicity of losartan. A stimulatory effect on phagocytic activity (P < 0.05) was observed with 10(-13) M and 10(-12 M) AII concentrations. The addition of losartan (up to10(-14) M) to the cell cultures blocked (P < 0.001) the phagocytosis indicating the involvement of AT1 receptors. In contrast, superoxide anion production was not affected by AII or losartan. The existence of AT1 and AT2 receptors in peritoneal macrophages was demonstrated by immunofluorescence microscopy.
