Mobilização social online da APP-Sindicato

This paper analyzes how the APP-Sindicato (Union of Workers in Public Education of Paraná) used the online platforms Facebook, YouTube and the organization’s website to publicize their demands and social mobilization during the strike of Paraná teachers in 2015, evaluating whether the initiatives are presented in an integrated way and seek to encourage popular participation in their actions. In addition to the literature review on the main concepts involving the theme we used the descriptive analysis and we examine the use of platforms. The analysis indicates that the use of platforms not follow an integrated format available, which indicates the lack of an integrated plan of public communication management via social media and the use of Information and Communication Technologies.En este artículo se analiza cómo el APP-Sindicato (Sindicato de los Trabajadores en Educacion Pública de Paraná) utiliza las plataformas en línea de Facebook, YouTube y la página web de la organización para dar a conocer sus demandas y su movilización social durante la huelga de los maestros de Paraná en 2015, evaluando si estas iniciativas se presentan de una manera integrada y tratan de incentivar la participación popular en sus acciones. Además de la revisión de la literatura sobre los principales conceptos relacionados con el tema, hacemos uso del análisis descriptivo y examinamos el uso de esas plataformas. El análisis indica que el uso de las plataformas nombradas no sigue un formato integrado disponible, lo que indica la falta de un plan integral de gestión de la comunicación pública a través de los medios sociales y del uso de las Tecnologías de Información y Comunicación.Este artigo analisa como a APP-Sindicato (Sindicato dos Trabalhadores em Educação Pública do Paraná) utilizou as plataformas online Facebook, YouTube e o website da entidade para divulgação de suas demandas e da mobilização social durante a greve dos professores do Paraná em 2015, avaliando se as iniciativas são apresentadas de forma integrada e se buscam incentivar a participação popular em suas ações.

Asma e gravidez: repercussões no recém-nascido

OBJETIVO: Descrever, numa coorte de nascimentos, aspectos socioeconômicos e comportamentais de gestantes com asma e analisar as repercussões desta sobre alguns parâmetros perinatais. MÉTODOS: Estudo observacional, transversal e analítico a partir de informações de parturientes da coorte de nascimentos ocorridos no período entre 8 de março e 15 de julho de 2005 nas maternidades da Grande Aracaju (SE). A identificação de asma nas gestantes foi obtida segundo informação destas a partir do diagnóstico emitido anteriormente por um médico. Foram analisadas variáveis epidemiológicas, obstétricas e perinatais. RESULTADOS: Das 4.757 parturientes incluídas no estudo, 299 (6,3%) eram asmáticas. As mães asmáticas tinham menor renda familiar e mais frequentemente procuraram assistência no pré-natal e no parto em serviços públicos que as mães sem asma. Embora somente 9,4% das gestantes asmáticas fumaram, e 27,6% ingeriram bebidas alcoólicas, as proporções em relação ao grupo controle foram significativamente maiores. Não se detectou associação entre asma e problemas obstétricos ou do recém-nascido. Não foi encontrada associação entre asma e parto cesariano, prematuridade ou recém-nascido sendo pequeno para a idade gestacional. CONCLUSÕES: O nível socioeconômico inferior parece ser um fator de risco para a asma

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

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

A VIOLÊNCIA NAS “CAPAS” DOS JORNAIS DIÁRIOS BRASILEIROS

O presente artigo trata da presença do tema violência nas primeiras páginas de alguns jornais brasileiros. O trabalho parte de dados coletados em 2007 por pesquisadores do Grupo de Pesquisa Mídia e Política da UEPG para as capas de seis jornais brasileiros (Folha de São Paulo, Estado de São Paulo, Gazeta do Povo, Folha de Londrina, Diário dos Campos e Jornal da Manhã). A metodologia utilizada na pesquisa é quantitativa de monitoramento da cobertura de jornais diários e visa identificar temas, formatos, tamanho em cm², elementos selecionadores e localização topográfica dos textos nas páginas dos jornais. Através de uma análise comparativa dos critérios de noticiabilidade entre veículos de circulação local, regional e nacional, testa-se a hipótese de que os jornais com circulação local apresentam uma lógica própria de noticiabilidade que os distingue daqueles com circulação regional e nacional, no que diz respeito ao tratamento dispensado ao tema violência em suas capas

Laboratório de Esquistossomose. Belo Horizonte, MG, BrazilStudies performed in the last 30 years demonstrated that a strain of B. tenagophila from the Taim Biological Reserve is completely resistant to Schistosoma mansoni infection. This resistance to parasite infection is a dominant characteristic during crossbreeding with susceptible B. tenagophila strains. These experiments also identified a 350 bp molecular marker that is exclusive to the Taim strain and does not occur in other geographic strains of this snail species. The Taim strain (Taim/RS) of Biomphalaria tenagophila was bred on a large scale, physically marked and introduced into a stream in which previous malacological analyses had revealed the presence of only parasite-susceptible B. tenagophila. Samples of offspring captured 4, 11 and 14 months after the introduction of the Taim strain were examined, and the susceptibility of the snails to S. mansoni infection dropped from 38.6–26.5% to 2.1% during the 14 months after the introduction of the Taim snail strain. A significant correlation was also observed between the absence of infection and the identification of the Taim molecular marker. These results demonstrate that the genetic marker from the Taim strain was successfully introduced into the wild snail population. In addition, a significant relationship exists between the marker and resistance to infection

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
