Juan César García: Social Medicine As Project And Endeavor.

This paper analyses some aspects of the trajectory of the Argentinian physician and sociologist Juan César García (1932-1984) in the field of Latin American Social Medicine. Three dimensions constituting his basic orientations are highlighted: the elaboration of systematic and reflective social thought; a critical attitude in questioning teaching and professional practices; a commitment to the institutionalization and dissemination of health knowledge.

Relações entre conteúdo e forma de conhecimentos e práticas pedagógicas em Geociências: imaginário de futuros professores numa disciplina de licenciatura

Pesquisas e reflexões sobre ensino, história e epistemologia das Ciências da Terra têm sido desenvolvidas, em grande parte, intimamente associadas às práticas docentes dos professores/pesquisadores universitários. Nessa mesma perspectiva, buscamos neste trabalho compreender relações que os estudantes de licenciatura em Geografia estabelecem entre o conteúdo/forma trabalhado numa disciplina universitária e o conteúdo/forma profissional, ou seja, pensado na relação com a escola básica, com o tornar-se professor. As respostas dos estudantes a uma questão por nós formulada indicou como eles representaram uma das atividades desenvolvidas na disciplina na relação com seu imaginário sobre ser professor da educação básica. As análises mostraram também que essas significações se produzem de maneiras muito diferentes entre os estudantes, fazendo intervir no imaginário a partir do qual essas significações se produzem, aspectos da memória escolar de alguns estudantes e da maneira como representam o conhecimento escolar e as práticas de ensino na disciplina Geografia da educação básica. As análises mostraram que a atividade não é transparente quanto ao que seja o "conteúdo" de ensino da atividade, posto que essas significações são o trabalho de diferentes memórias discursivas, implicado em diferentes posições-aluno. Este estudo aponta para a importância de considerar e para a possibilidade de trabalhar com os imaginários dos futuros professores sobre ensino na relação que estabelecem com os conteúdos/formas em suas disciplinas científicas universitárias.

Controle social e gestão participativa em saúde pública em unidades de saúde do município de Campo Grande, MS, 1994-2002

A participação social no Brasil evoluiu de movimento operário e de sindicatos, culminando na institucionalização através de Conselhos. Na área da saúde, foi legalizada pela Lei 8142/90. O objetivo deste estudo é conhecer a prática do controle social exercida em Conselhos de Unidades e sua influência nas políticas de saúde do município de Campo Grande, MS. Foram feitos cinco estudos de caso, tendo como fonte principal as atas de reuniões e como referencial de análise um documento do Ilpes/Claps (1975). Os Conselhos organizam-se em plenário, com coordenador, secretário, composição hoje paritária, representatividade reduzida e periodicidade mensal. O processo decisório contempla principalmente elementos técnico-administrativos e técnico-operacionais. No período 1998-2002, o controle social fortaleceu-se por encaminhamentos mais concretos, mas a capacidade de deliberação precisa ser fortalecida por uma capacitação que inclua elementos técnicos, políticos e administrativos, representatividade, fortalecimento da cidadania, divulgação intensa das atividades dos Conselhos, inclusive na mídia, maior mobilização social e articulação entre os vários Conselhos e instâncias municipais que fazem interface com o setor de saúde.

Queimadas nos canaviais e perspectivas dos cortadores de cana-de-açúcar em Macatuba, São Paulo

A lei nº 11.241/2002 do estado de São Paulo proíbe a queima de cana-de-açúcar pré-colheita devido ao alto impacto que a fumaça desse processo causa na saúde coletiva e no meio ambiente. De modo gradativo, a previsão inicial era de que a proibição fosse efetiva em 2031. Posteriormente, acordo entre governo do Estado e União da Indústria de Cana-de-açúcar (Unica), estabeleceu redução do prazo para 2017. A cana-de-açúcar, quando não queimada, exige muito mais esforço dos cortadores, diminuindo a produtividade do corte manual em comparação às máquinas colheitadeiras. A ausência das queimadas traz benefícios à saúde e ao meio ambiente, no entanto, pouco ainda se sabe a respeito das consequências da mecanização para a mão de obra rural nos canaviais. Este artigo busca analisar esse quadro de incerteza sobre o que ocorrerá do ponto de vista dos cortadores de cana e o reconhecimento das consequências da lei em suas vidas. Durante a safra de cana de 2006, foram aplicados questionários a 40 cortadores de cana, de diferentes idades e gênero, no bairro Jardim América, em Macatuba-SP, em suas casas ou na rua. Perguntas qualitativas e quantitativas que abordavam temas socioeconômicos, de saúde, reconhecimento da lei e perspectivas de trabalho. Os entrevistados apresentaram um dilema entre o ar limpo e a perspectiva de trabalho. Muitos se apresentaram indecisos e sem incentivos a trabalhar em outros setores, apesar de grande parte gostar do local onde vive e se interessar por continuar a trabalhar na agricultura

Forest certification in Amazonia: standards matter

Forest Stewardship Council (FSC) certification promises international consumers that `green-label` timber has been logged sustainably. However, recent research indicates that this is not true for ipe (Tabebuia spp.), currently flooding the US residential decking market, much of it logged in Brazil. Uneven or non-application of minimum technical standards for certification could undermine added value and eventually the certification process itself. We examine public summary reports by third-party certifiers describing the evaluation process for certified companies in the Brazilian Amazon to determine the extent to which standards are uniformly applied and the degree to which third-party certifier requirements for compliance are consistent among properties. Current best-practice harvest systems, combined with Brazilian legal norms for harvest levels, guarantee that no certified company or community complies with FSC criteria and indicators specifying species-level management. No guidelines indicate which criteria and indicators must be enforced, or to what degree, for certification to be conferred by third-party assessors; nor do objective guidelines exist for evaluating compliance for criteria and indicators for which adequate scientific information is not yet available to identify acceptable levels. Meanwhile, certified companies are expected to monitor the long-term impacts of logging on biodiversity in addition to conducting best-practice forest management. This burden should reside elsewhere. We recommend a clarification of `sustained timber yield` that reflects current state of knowledge and practice in Amazonia. Quantifiable verifiers for best-practice forest management must be developed and consistently employed. These will need to be flexible to reflect the diversity in forest structure and dynamics that prevails across this vast region. We offer suggestions for how to achieve these goals.

Oral Hygiene Indirect Instruction and Periodic Reinforcements: Effects on Index Plaque in Schoolchildren

The aim of this study was to evaluate the effectiveness of the indirect instruction and the influence of the periodic reinforcement on the plaque index in schoolchildren. Forty schoolchildren aged from 7 to 9 years old were selected from a public school. After determining the initial O`Leary Plaque Index all schoolchildren were submitted to a program for oral hygiene through indirect instruction - ""The Smiling Robot"". The schoolchildren were divided into 2 groups: with and without motivation reinforcement. The index plaque exam was performed in both groups after 30, 60 and 90 days of the educational program. Comparing the groups, the plaque index decreasing could be observed in the group with reinforcement with statistically significant difference. For the group with reinforcement, statistically significant difference among the evaluations was found. For the group without reinforcement, significant decrease in the plaque index was found after 30 days when compared to the first, third and fourth evaluations. The indirect instruction with ""The Smiling Robot ""promoted a positive initial impact on the decrease of plaque index in the schoolchildren. The periodic reinforcements showed snore suitable results and significant reduction of the plaque index in the course of the evaluations.

From idola conceptiones to discourse analysis: A response to Bart Crum

Crum's notion of idola as a conceptual fallacy is interesting, somewhat helpful, yet potentially limiting in a critique of research in PE if one is to accept a postmodern or poststructuralist position. In line with a poststructuralist position, a strength in Crum's application of idola is the recognition that research in PE is constituted by the researcher and their social world which, in turn, constitutes the researcher. Limitations to Crum's idola thesis arise when the notion is used to suggest that as a result of the researcher's lack of conceptual clarity, the quest for knowledge or truth about PE pedagogy is undermined as this assumes that meanings can be unequivocal and precede a linear research process. In contrast, this response argues that a priority in research should be to examine how, and under what conditions, particular discourses come to shape PE practices in schools and universities. In a postmodern world, conceptual clarity should not be the goal but rather a coming to understand how PE knowledge and practice is being constructed across sites and contexts.

Conhecimento e formação de futuros professores dos primeiros anos – o sentido de número racional

Nos últimos anos o conhecimento do professor tem vindo a ser reconhecido como um dos aspetos nucleares no, e para o, desenvolvimento do conhecimento matemático dos alunos. Atendendo a essa centralidade, a formação deverá focar-se onde é, efetivamente, necessária, de modo a potenciar um incremento do conhecimento dos alunos, pelo conhecimento (e práticas) dos professores. Sendo os números racionais um dos tópicos problemáticos para os alunos, é fundamental identificar quais as situações matematicamente (mais) críticas para os professores de modo que, pela formação facultada, possam deixar de o ser. Neste artigo, tendo por foco o conhecimento matemático do professor e as suas especificidades, discutimos alguns aspetos desse conhecimento de futuros professores sobre números racionais, em concreto o sentido de número racional, identificando as suas componentes mais problemáticas e equacionando alguns dos porquês em que se sustentam. Terminamos com algumas considerações sobre implicações para a formação de professores e responsabilidade dos seus formadores.

Readability of medicinal package leaflets: a systematic review

OBJECTIVE To review studies on the readability of package leaflets of medicinal products for human use.METHODS We conducted a systematic literature review between 2008 and 2013 using the keywords “Readability and Package Leaflet” and “Readability and Package Insert” in the academic search engine Biblioteca do Conhecimento Online,comprising different bibliographic resources/databases. The preferred reporting items for systematic reviews and meta-analyses criteria were applied to prepare the draft of the report. Quantitative and qualitative original studies were included. Opinion or review studies not written in English, Portuguese, Italian, French, or Spanish were excluded.RESULTS We identified 202 studies, of which 180 were excluded and 22 were enrolled [two enrolling healthcare professionals, 10 enrolling other type of participants (including patients), three focused on adverse reactions, and 7 descriptive studies]. The package leaflets presented various readability problems, such as complex and difficult to understand texts, small font size, or few illustrations. The main methods to assess the readability of the package leaflet were usability tests or legibility formulae. Limitations with these methods included reduced number of participants; lack of readability formulas specifically validated for specific languages (e.g., Portuguese); and absence of an assessment on patients literacy, health knowledge, cognitive skills, levels of satisfaction, and opinions.CONCLUSIONS Overall, the package leaflets presented various readability problems. In this review, some methodological limitations were identified, including the participation of a limited number of patients and healthcare professionals, the absence of prior assessments of participant literacy, humor or sense of satisfaction, or the predominance of studies not based on role-plays about the use of medicines. These limitations should be avoided in future studies and be considered when interpreting the results.

Schistosomiasis mansoni in an area of low transmission: II. Risk factors for infection

Risk factors for Schistosoma mansoni infection were identified using a 1:1 matched case-control design. The work was conducted in the municipality of Pedro de Toledo, São Paulo State, Brazil, an area where the snail host is Biomphalaria tenagophila. Information on water contact patterns, knowledge, attitudes and pratices (kap), socioeconomic and sanitary conditions were obtained by mean of questionnaires. The crude odds ratio estimates and the adjusted odds ratio estimates using the logistic regression model are presented. Most of the examined individuals admitted recent water contacts (90.6% of the cases). The most frequent reason for contact was swimming, playing and fishing and the preferential site of contact was the river. According to the logistic regression technique, the main risk factors for infection were: a) water contact through swimming, playing and fishing; b) fording; c) bad hygiene. We concluded that recreational activities are the main reasons for schistosomiasis transmission in Pedro de Toledo and leisure alternatives should be offered to the local population.

Recursos para la alfabetización mediática: investigación y propuestas para niños

Mucho se ha investigado sobre la educación en medios, su importancia y objetivos. Más allá de las Directivas, resoluciones o recomendaciones, la investigación en esta área ha permitido profundizar y solidificar sus fundamentos, al tiempo que ha facilitado el reconocimiento de sus puntos más débiles u omisiones. Uno de los puntos críticos destacados por la formación y por el trabajo de investigación que se ha desarrollado en la Universidad de Miño (Portugal) durante los últimos 20 años, es la inexistencia de recursos y materiales que puedan utilizarse para la promoción de la educación en los medios de comunicación en diferentes contextos. De esta forma, independientemente de los recursos y materiales, se genera la importancia de la transferencia de conocimientos a la práctica, la trascendencia de la mediación del conocimiento producido a su público. Esta preocupación fue la base principal del proyecto titulado «Recursos para la alfabetización mediática» llevado a cabo en el Centro de Estudios de Comunicación y Sociedad y financiado por Evens Foundation (Bélgica). Este trabajo presenta sucintamente los procesos de creación y los resultados generados por estos recursos, centrados en tres medios: televisión, videojuegos e Internet y redes sociales.

Analysis of GPCR properties of Frizzled receptors and establishment of the "in vitro" platform for screening of Frizzled agonists/antagonists as potential therapeutic agents

Morphogens of the Wnt protein family are the secreted lipoglycoprotein ligands which initiate several pathways heavily involved in the coordination of various developmental stages of organisms in the majority of animal species. Deregulation of these pathways in the adult leads to formation and sustaining of multiple types of cancer. The latter notion is reinforced by the fact that the very discovery of the first Wnt ligand was due to its role as the causative factor of carcinogenic transformation (Nusse and Varmus, 1982). Nowadays our knowledge on Wnt signaling has "moved with the times" and these pathways were identified to be often crucial for tumor formation, its interactions with the microenvironment, and promotion of the metastases (Huang and Du, 2008; Zerlin et al., 2008; Jessen, 2009). Thus the relevance of the pathway as the target for drug development has further increased in the light of modern paradigms of the complex cancer treatments which target also spreading and growth- promoting factors of tumors by specific and highly efficient substances (Pavet et al., 2010). Presently the field of the Wnt-targeting drug research is almost solely dominated by assays based on transcriptional activation induced by the signaling. This approach resulted in development of a number of promising substances (Lee et al., 2011). Despite its effectiveness, the method nevertheless suffers from several drawbacks. Among the major ones is the fact that this approach is prone to identify compounds targeting rather downstream effectors of the pathway, which are indiscriminately used by all the subtypes of the Wnt signaling. Additionally, proteins which are involved in several signaling cascades and not just the Wnt pathway turn out as targets of the new compounds. These issues increase risks of side effects due to off-target interactions and blockade of the pathway in healthy cells. In the present work we put forward a novel biochemical approach for drug development on the Wnt pathway. It targets Frizzleds (Fzs) - a family of 7-transmbembrane proteins which serve as receptors for Wnt ligands. They offer unique properties for the development of highly specific and effective drugs as they control all branches of the Wnt signaling. Recent advances in the understanding of the roles of heterotrimeric G proteins downstream from Fzs (Katanaev et al., 2005; Liu et al., 2005; Jernigan et al., 2010) suggest application of enzymatic properties of these effectors to monitor the receptor-mediated events. We have applied this knowledge in practice and established a specific and efficient method based on utilization of a novel high-throughput format of the GTP-binding assay to follow the activation of Fzs. This type of assay is a robust and well-established technology for the research and screenings on the GPCRs (Harrison and Traynor, 2003). The conventional method of detection involves the radioactively labeled non-hydrolysable GTP analog [35S]GTPyS. Its application in the large-scale screenings is however problematic which promoted development of the novel non-radioactive GTP analog GTP-Eu. The new molecule employs phenomenon of the time-resolved fluorescence to provide sensitivity comparable to the conventional radioactive substance. Initially GTP-Eu was tested only in one of many possible types of GTP-binding assays (Frang et al., 2003). In the present work we expand these limits by demonstrating the general comparability of the novel label with the radioactive method in various types of assays. We provide a biochemical characterization of GTP-Eu interactions with heterotrimeric and small GTPases and a comparative analysis of the behavior of the new label in the assays involving heterotrimeric G protein effectors. These developments in the GTP-binding assay were then applied to monitor G protein activation by the Fz receptors. The data obtained in mammalian cultured cell lines provides for the first time an unambiguous biochemical proof for direct coupling of Fzs with G proteins. The specificity of this interaction has been confirmed by the experiments with the antagonists of Fz and by the pertussis toxin-mediated deactivation. Additionally we have identified the specificity of Wnt3a towards several members of the Fz family and analyzed the properties of human Fz-1 which was found to be the receptor coupled to the Gi/o family of G proteins. Another process playing significant role in the functioning of every GPCR is endocytosis. This phenomenon can also be employed for drug screenings on GPCRs (Bickle, 2010). In the present work we have demonstrated that Drosophila Fz receptors are involved in an unusual for many GPCRs manifestation of the receptor-mediated internalization. Through combination of biochemical approaches and studies on Drosophila as the model organism we have shown that direct interactions of the Fzs and the α-subunit of the heterotrimeric G protein Go with the small GTPase Rab5 regulate internalization of the receptor in early endosomes. We provide data uncovering the decisive role of this self-promoted endocytosis in formation of a proper signaling output in the canonical as well as planar cell polarity (PCP) pathways regulated by Fz. The results of this work thus establish a platform for the high-throughput screening to identify substances active in the cancer-related Wnt pathways. This methodology has been adjusted and applied to provide the important insights in Fz functioning and will be instrumental for further investigations on the Wnt-mediated pathways.
