    A pandemia COVID-19 trouxe muitas mudan√ßas em nossas vidas e tamb√©m nas organiza√ß√Ķes. A partir do regime de trabalho remoto, com o confinamento, embaralhamos definitivamente o p√ļblico e o privado em nossas casas, as escolhas passaram a n√£o estar somente em benef√≠cio de alguns, mas a n√≠vel de toda a sociedade, e tivemos que lidar com informa√ß√Ķes globalmente dispersas entre os m√ļltiplos atores. Nesse cen√°rio, que foi interconectado por dispositivos tecnol√≥gicos, as rela√ß√Ķes participativas nas organiza√ß√Ķes mostraram-se essenciais. Neste estudo, fazemos uma revis√£o hist√≥rica e conceitual da comunica√ß√£o interna e problematizamo-la nas organiza√ß√Ķes contempor√Ęneas, a partir da premissa de que qualquer processo comunicacional necessita de equil√≠brio pela participa√ß√£o. Entendendo a participa√ß√£o como uma efetiva redistribui√ß√£o de poder, propomos uma (re)organiza√ß√£o da comunica√ß√£o interna que permita a constru√ß√£o de espa√ßos sociais, interativos, de partilha, de responsabilidades, de planeamentos e tomada de decis√Ķes. Assim, a comunica√ß√£o interna √© percebida no estudo como uma constru√ß√£o simb√≥lica de significados, envolvendo todos os colaboradores, em todos os n√≠veis, por meio da cria√ß√£o de um ambiente de trabalho como um espa√ßo social, integrativo. Ressalta-se ainda que √© preciso que profissionais de comunica√ß√£o reconhe√ßam sua capacidade e responsabilidade de funcionar como agentes de mudan√ßa nos locais de trabalho, observem as estruturas e experi√™ncias proporcionadas pelas novas tecnologias de comunica√ß√£o e ajudem a criar um ambiente organizacional que proporcione a participa√ß√£o dos colaboradores de forma ativa

    This work is part of the debate on a topic of particular relevance today, worldwide: the increasing use of biotechnology in the production of genetically modified foods and the public knowledge about it. Aiming to know the opinion of consumers in the city of Fortaleza, Brazil, we applied a structured questionnaire with six objective and dissertative questions about the existence, consummation, to health risk, labeling and disclosure related to transgenic foods. Of the 60 people interviewed, 67% said they had some knowledge about transgenic foods, with 60% confirming they are consumers of such products. However, the majority of respondents (68%) were unable to report on the possible benefits or harms of eating transgenic foods, revealing the absence of a structured and scientific knowledge on the subject. We found that 48% do not agree with the use of biotechnology in the modification of food and 73% said that the information contained on the labeling of genetically modified foods is not clear. We observed that the media exerts great influence over the choice of these foods. In short, it becomes clear that consumers do not have conclusive opinions regarding the issue of transgenic foods, feeling insecure to give their opinion on the subject.Este trabalho se insere no debate de um tema relevante na atualidade, em √Ęmbito mundial: o crescente uso da biotecnologia na produ√ß√£o de alimentos transg√™nicos e o saber p√ļblico sobre o assunto. Visando conhecer a opini√£o de consumidores da cidade de Fortaleza, foi aplicado um question√°rio estruturado, com 6 quest√Ķes objetivas e dissertativas a respeito da exist√™ncia, consuma√ß√£o, risco √† sa√ļde, rotulagem e divulga√ß√£o de alimentos transg√™nicos. Das 60 pessoas entrevistadas, 67% responderam que tinham algum conhecimento sobre alimentos transg√™nicos, e 60% afirmaram consumir tais produtos. A maioria dos entrevistados (68%) n√£o soube informar sobre os poss√≠veis benef√≠cios ou malef√≠cios do consumo de alimentos transg√™nicos, revelando aus√™ncia de conhecimento estruturado e cient√≠fico sobre o assunto. Verificou-se, ainda, que 48% n√£o concordaram com a utiliza√ß√£o da biotecnologia na modifica√ß√£o dos alimentos, e 73% declararam que as informa√ß√Ķes contidas no r√≥tulo dos alimentos geneticamente modificados n√£o s√£o claras. Observou-se que a m√≠dia exerce grande poder de influ√™ncia nos consumidores sobre a escolha desses alimentos. Conclui-se que a maioria dos consumidores n√£o apresentam opini√Ķes contundentes sobre os transg√™nicos, sentindo-se inseguros em opinar sobre o tema

    The egg is an inexpensive and highly nutritious food that is part of the Brazilian food habits. However, eggs are one of the most important causative agents of salmonellosis, diseases caused by bacteria of the genus Salmonella, belonging to the family Enterobacteriaceae, of which there are more than 2,500 serotypes; however, 80-90 are important to the health of animals and humans. Therefore, the aim of this study was to evaluate the level of contamination by Salmonella spp. in quail and chicken eggs (shell and yolk) commercialized in Fortaleza/CE by a specific polymerase chain reaction (PCR). The shell and yolk of 36 egg were analyzed by PCR using specific primers that amplify a fragment of 284 base pairs (bp) from the invA gene of Salmonella thyfimurium. The results show that 2.6% of the yolks and 5.3% shells were positive for Salmonella. Comparing the different types of eggs, 11.1% of the white type were positive in shell for Salmonella, 7.1% of the yolk from quail eggs were positives and no contamination was detected in red eggs. In conclusion, the PCR was effective to demonstrate that chicken and quail eggs sold in Fortaleza-CE showed salmonella contamination.O ovo √© um alimento econ√īmico e de alto valor nutritivo que faz parte do h√°bito alimentar do povo brasileiro. Entretanto, √© um dos principais agentes causadores de salmonelose, enfermidade provocada por bact√©rias do g√™nero Salmonella, pertencentes √† fam√≠lia Enterobacteriaceae, sendo conhecidos mais de 2.500 sorotipos, dos quais 80 a 90 t√™m import√Ęncia para a sa√ļde de animais e seres humanos. Diante dessa problem√°tica, o presente trabalho teve como objetivo avaliar o n√≠vel de contamina√ß√£o por Salmonella spp. em ovos de galinha e codorna (casca e gema) comercializados em Fortaleza/CE, por meio da t√©cnica de PCR. Foram analisadas amostras de casca e gema de 36 ovos dos tipos branco, vermelho e codorna por rea√ß√£o em cadeia da polimerase (PCR), utilizando oligonucleot√≠deos espec√≠ficos que conseguem amplificar um fragmento de 284 pares de bases (bp) do gene invA de Salmonella thyfimurium. Os resultados mostram que 2,6% da parte interna dos ovos e 5,3% da casca foram positivos para salmonela. Na compara√ß√£o entre os diferentes tipos de ovos, das 18 amostras de ovos brancos, 11,1% apresentaram positividade na casca para Salmonella; das 14 de ovos de codorna, cerca de 7,1% das gemas apresentavam-se positivas e os ovos vermelhos apresentaram aus√™ncia de contamina√ß√£o. Conclui-se que a t√©cnica de PCR foi eficiente para demonstrar que ovos de galinha e codorna comercializados na cidade de Fortaleza-CE apresentaram contamina√ß√£o por salmonela

    A green synthetic route was developed to prepare silver nanoparticles (AgNPs) in aqueous solution for biological applications. Eschweilenol C, a compound derivative ellagic acid was identified as the main constituent of the aqueous fraction of the ethanolic extract of Terminalia fagifolia Mart. by NMR analysis. In the green synthesis, the ethanolic extract of T. fagifolia and its aqueous fraction were used to promote silver reduction and nanoparticle stabilization. The synthesized AgNPs presented a spherical or polygonal morphology shape by TEM analysis and AgNPs showed high levels of antioxidant and considerable antibacterial and antifungal activities. Synthesized nanoparticles presented significant antioxidant activity by sequestration of DPPH and ABTS radicals, in addition to iron reduction (FRAP assay) and measurement of antioxidant capacity in ORAC units, in addition, AgNP synthesized with the aqueous fraction also demonstrated antioxidant potential in microglial cells. Gram-positive and Gram-negative bacteria were susceptible to growth inhibition by the nanoparticles, among which the AgNPs formed by the ethanolic extract was the most effective. The data obtained by AFM images suggested that AgNPs could lead to the lysis of bacteria and subsequent death. The antifungal assays showed high efficiency against yeasts and dermatophytes. This work represents the first description of antifungal activity by AgNPs against Fonsecaea pedrosoi, the etiologic agent of chromoblastomycosis. In relation to biocompatibility, the AgNPs induced lower haemolysis than AgNO3.We thank Herbert Kogler and Reinhard Wimmer for the identification of Eschweilenol C.

    Tree diversity and above-ground biomass in the South America Cerrado biome and their conservation implications

    Get PDF
    Less than half of the original two million square kilometers of the Cerrado vegetation remains standing, and there are still many uncertainties as to how to conserve and prioritize remaining areas effectively. A key limitation is the continuing lack of geographically-extensive evaluation of ecosystem-level properties across the biome. Here we sought to address this gap by comparing the woody vegetation of the typical cerrado of the Cerrado‚ÄďAmazonia Transition with that of the core area of the Cerrado in terms of both tree diversity and vegetation biomass. We used 21 one-hectare plots in the transition and 18 in the core to compare key structural parameters (tree height, basal area, and above-ground biomass), and diversity metrics between the regions. We also evaluated the effects of temperature and precipitation on biomass, as well as explored the species diversity versus biomass relationship. We found, for the first time, both that the typical cerrado at the transition holds substantially more biomass than at the core, and that higher temperature and greater precipitation can explain this difference. By contrast, plot-level alpha diversity was almost identical in the two regions. Finally, contrary to some theoretical expectations, we found no positive relationship between species diversity and biomass for the Cerrado woody vegetation. This has implications for the development of effective conservation measures, given that areas with high biomass and importance for the compensation of greenhouse gas emissions are often not those with the greatest diversity

    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

    Abstract Objectives: to analyze the perception of a nursing team in the implantation of a Reception with Risk Classification (RRC) sector for pregnant women. Methods: a descriptive cross-sectional study with a qualitative approach performed in a private hospital and linked to the Public Health System in Feira de Santana city in Bahia State in 2016. 10 nursing team professionals participated in the study that provided direct care for the pregnant women who were in labor and in puerperium. A semi-structured questionnaire was applied with questions identifying and characterizing their sociodemographic profile and an interview addressing questions about RRC sector, the advantages of implanting RRC sector to care for the pregnant women in labor and the possible changes in the implantation in the professionals’ routine. Results: the interviewees recognize that the RSRC is a way to administrate in the health services, reorganizing the work process, ensuring the quality of care, so its implementation is useful to differentiate care for pregnant women, with humanization and sensitivity, and create a bond among the professionals and the health users. Conclusions: the implementation of the RRC sector establishes improvement that ensures a relationship of trust among the health users and the professionals and the effectiveness of care for pregnancy emergencies and urgencies
