A diversidade lingüística da internet como reação contra-hegemônica das tendências de centralização do império

A Internet nasceu nos EUA como variação de um projeto militar muito específico. No início, quase a totalidade da comunicação em rede era em língua inglesa, pois a maioria das pessoas envolvidas nos projetos provinha dos EUA, ou de comunidades científicas nas quais o inglês era língua franca. Com o aumento da utilização da Internet em diferentes países, a hegemonia do inglês passou a ser revista. Em 1998, o inglês já havia sofrido queda de 15% do seu total, devido principalmente à proliferação da rede e à produção de conteúdos locais nas línguas nacionais. O presente trabalho busca perceber quais são as causas do crescente aumento de línguas locais na produção da Internet e identificar as formas de reação contra-hegemônica empreendida pelo uso desta ferramenta como campo fértil para a produção e difusão de idéias, informações, conteúdos, conhecimentos e saberes.

Prevalence rate and reasons for refusals of influenza vaccine in the elderly

RESUME Peu d'informations sont disponibles concernant la prévalence et les motifs de refus de la vaccination contre la grippe dans la population âgée. Le but de notre recherche était d'investiguer les vrais motifs de refus de la vaccination (c'est-à-dire pas uniquement les raisons de non-vaccination parfois indépendantes du patient lui- même) chez les personnes âgées. Tous les patients ambulatoires de plus de 65 ans consultant la Policlinique Médicale Universitaire (PMU) de Lausanne ou leur médecin traitant durant les périodes de vaccination contre la grippe 1999-2000 et 2000-2001 ont été inclus. Chaque patient recevait une information sur la grippe et ses complications, de même que sur la nécessité de la vaccination, son efficacité et ses effets seconda ires éventuels. En l'absence de contre-indication, la vaccination était proposée. En cas de refus, les motifs étaient investigués par une question ouverte. Sur 1398 sujets inclus, 148 (12%) ont refusé la vaccination. Les raisons principales de refus étaient la perception d'être en bonne santé (16%), de ne pas être susceptible à la grippe (15%) ou le fait de ne jamais avoir été vacciné contre la grippe dans le passé (15%). On retrouvait également la mauvaise expérience personnelle ou d'un proche lors d'une vaccination (15%) et l'impression d'inutilité du vaccin (10%). 17% des personnes interrogées ont donné des motifs autres et 12% n'ont pas explicité leur non-acceptation. Les refus de vaccination contre la grippe dans la population âgée sont essentiellement liés aux convictions intimes du patient quant à son état de santé et à sa susceptibilité à la grippe, de même qu'à l'efficacité supposée de la vaccination. La résistance au changement semble être un obstacle majeur à l'introduction de la vaccination chez les personnes de plus de 65 ans. SUMMARY More knowledge on the reasons for refusal of the influenza vaccine in elderly patients is essential to target groups for additional information, and hence improve coverage rate. The objective of the present study was to describe precisely the true motives for refusal. All patients aged over 64 who attended the Medical Outpatient Clinic, University of Lausanne, or their private practitioner's office during the 1999 and 2000 vaccination periods were included. Each patient was informed on influenza and its complications, as well as on the need for vaccination, its efficacy and adverse events. The vaccination was then proposed. In case of refusal, the reasons were investigated with an open question. Out of 1398 patients, 148 (12%) refused the vaccination. The main reasons for refusal were the perception of being in good health (16%), of not being susceptible to influenza (15%), of not having had the influenza vaccine in the past (15%), of having had a bad experience either personally or a relative (15%), and the uselessness of the vaccine (10%). Seventeen percent gave miscellaneous reasons and 12% no reason at all for refusal. Little epidemiological knowledge and resistance to change appear to be the major obstacles for wide acceptance of the vaccine by the elderly.

Novo isolado de Bacillus thuringiensis efetivo contra a lagarta-do-cartucho

Com o objetivo de encontrar princípios ativos que possam ser usados no controle da lagarta-do-cartucho, Spodoptera frugiperda (Smith, 1797), foram testados 205 isolados de Bacillus, provenientes de diferentes regiões brasileiras, contra larvas deste inseto. Apenas um isolado de B. thuringiensis subsp. kurstaki, denominado S93, causou 100% de mortalidade. A CL50 da mistura esporos-cristais do isolado S93 para larvas de 3º estádio de S. frugiperda foi de 37,0 ng/mL, enquanto a da estirpe HD-1 de B. thuringiensis subsp. kurstaki isolada do produto Dipel foi de 177,73 mg/mL, demonstrando ser o novo isolado muito mais tóxico contra a lagarta-do-cartucho do que HD-1-Dipel.

Bilateral anterior ischemic optic neuropathy following influenza vaccination.

Optic neuritis is an occasional complication of vaccination. Visual loss can be unilateral or bilateral, and most patients recover substantially without treatment. The presumptive mechanism is an immune-mediated demyelinating injury of the optic nerve. We report two patients who had permanent visual loss following influenza vaccination. Their pattern of visual loss, segmental optic disc changes, and failure of visual recovery were atypical for demyelinating optic neuritis and reminiscent of a primary ischemic injury to the optic nerve. We speculate that an immune complex-mediated vasculopathy following vaccination can cause anterior ischemic optic neuropathy. Clinicians should be aware of this entity because of the less favorable prognosis for visual recovery in these cases.

Controle químico de fungos associados a sementes de sorgo e proteção contra fungos do solo

Este trabalho teve como objetivo avaliar a eficiência de alguns fungicidas no controle de fungos associados a sementes de sorgo cultivar CMS 182R e na proteção delas contra fungos do solo. A microbiota das sementes de sorgo, composta por Fusarium moniliforme, Penicillium spp., Alternaria tenuis, Cladosporium spp. e Phoma sorghina, foi patogênica a essas sementes, e os fungos Pythium aphanidermatum e Sclerotium rolfsii, infectantes do solo de monocultivo de sorgo, também se mostraram patogênicos. Os fungicidas captan, thiram, captan + thiabendazole, thiram + thiabendazole, iprodione + thiram e tolylfluanid foram os mais eficientes no controle não só de toda a microbiota das sementes, como também na proteção das sementes contra Pythium aphanidermatum e Sclerotium rolfsii.

The ethics committee proposes the document as a foundation for decision making in preparing for and responding to pandemic influenza. The document addresses four ethical or moral focal points that public health and health care workers may need to address during a public health disaster.

Estirpes de Bacillus thuringiensis efetivas contra insetos das ordens Lepidoptera, Coleoptera e Diptera

O objetivo deste trabalho foi selecionar entre 300 estirpes de Bacillus thuringiensis as efetivas simultaneamente contra larvas de Spodoptera frugiperda J.E. Smith e Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae), Anthonomus grandis Boheman (Coleoptera: Curculionidae), Aedes aegypti Linnaeus e Culex quinquefasciatus Say (Diptera: Culicidae). Foram selecionadas duas estirpes de B. thuringiensis, denominadas S234 e S997, que apresentaram atividade contra as três ordens de insetos. As estirpes foram caracterizadas por métodos morfológicos, bioquímicos e moleculares. As mesmas apresentaram duas proteínas principais de 130 e 65 kDa, produtos de reação em cadeia da polimerase de tamanho esperado para a detecção dos genes cry1Aa, cry1Ab, cry1Ac, cry1B e cry2 e cristais bipiramidais, cubóides e esféricos.

Does Influenza Vaccination Induce De Novo HLA Alloantibody Formation in Transplant Recipients?

Introduction: Infl uenza vaccination is recommended for all solid organ transplant recipients. However, some centers are reluctant to give annual vaccination due to concerns about precipitating rejection. A proposed mechanism of this is vaccineinduced development of cellular and humoral responses to donor HLA antigens. We studied the induction of HLA Ab in a cohort of lung transplant recipients receiving infl uenza vaccination. Methods: Adult lung transplant recipients were immunized with 0.5 mL intramuscular seasonal infl uenza vaccine followed by 0.1 mL intradermal booster at 4 weeks as part of a previous study. Sera were collected pre-vaccination and at 4, 8 weeks post-vaccination. Post-vaccination sera were analyzed for HLA Ab using fl owPRA specifi c beads (One Lambda Inc). A positive result was defi ned as 5%. Positive samples were further analyzed for antibody specifi city by single antigen bead testing. Pre-vaccination sera were tested only only if post-vaccination sample screen was positive for HLA Ab. The presence of HLA Ab was correlated to vaccine seroresponse and rejection episodes. Results: Sixty patients were included with equal numbers of men and women. Mean age of patients was 47.3 years (range 20.7-72.4). Median time post-transplant was 1.3 years (range 85 days - 17 years). One patient was excluded due to an uninterpretable baseline screen result. 16/59 (27.1%) patients were positive for HLA Ab both in both pre- and post-vaccination samples. Of these, 12/16 (75%) had antibody against HLA Class I (majority A30,A31,B27,B44), 2/16 (12.5%) had antibody against HLA class II (majority DQ4, DQ7), and 2/16 (12.5%) had antibody against both Class I & II. There was no signifi cant increase in existing HLA Ab post-vaccination. Of the 16 patients, only one (6.3%) patient had de novo HLA Ab and this was determined to be non donor specifi c. Factors such as gender, time from transplant, immunosuppression, and acute rejection episodes did not correlate with presence of HLA Ab. HLA Ab was not associated with seroconversion to to vaccine antigens. Conclusions: Our data support that receiving the annual infl uenza vaccine does not lead to the generation of de novo donor specifi c antibodies in lung transplant recipients or upregulation of existing HLA Ab.

La violencia doméstica contra las mujeres y el desarrollo de estándares normativos de derechos humanos en el Consejo de Europa

La violencia doméstica contra las mujeres constituye una forma de discriminación basada exclusivamente en el género que impide a un amplio sector de la población europea disfrutar plenamente de los derechos que le son internacionalmente reconocidos. Pese a la dimensión paneuropea del problema y a su compromiso de salvaguardar y dar la mayor efectividad a los derechos humanos, el Consejo de Europa ha evitado durante años imponer obligaciones jurídicas internacionales a los Estados en relación con la erradicación de la violencia contra las mujeres, incluida la violencia doméstica (excepción hecha de las disposiciones del Convenio europeo de derechos humanos, aunque se aplicaban sin tener en cuenta un enfoque de género). Sin embargo, ante los insuficientes resultados obtenidos se ha considerado necesario disponer de un tratado europeo en la materia, la Convención sobre la prevención y la lucha contra la violencia contra las mujeres y la violencia doméstica, que establece un marco integral de actuación sobre la base de los principios de igualdad y no discriminación y de diligencia debida.

Who knew? Awareness of being recommended for influenza vaccination among US adults

Please cite this paper as: Maurer et al. (2012) Who knew? Awareness of being recommended for influenza vaccination among US adults. Influenza and Other Respiratory Viruses 6(4), 284-290. Background  Starting with the 2010-2011 influenza season, the Advisory Committee on Immunization Practices at the US Centers for Disease Control and Prevention recommends annual influenza vaccination to all people aged 6 months and older unless contraindicated. Objectives  To measure perceived influenza vaccination recommendation status among US adults (n = 2122) and its association with socio-demographic characteristics and recommendation status during the 2009-2010 pandemic influenza season. Methods  We analyze nationally representative data from longitudinal Internet surveys of US adults conducted in November-December 2009 and September-October 2010. Results  During the 2010-2011 vaccination season, 46·2 percent (95%-CI: 43·3-49·1%) of US adults correctly reported to be covered by a government recommendation for influenza vaccination. Awareness of being covered by a government influenza vaccination recommendation was statistically significantly higher among non-working adults and adults who had been recommended for seasonal vaccination or both seasonal and H1N1 vaccination during the 2009-2010 pandemic influenza vaccination season. Conclusion  Our results highlight that a majority of US adults do not know that they are recommended for annual influenza vaccination by the government. The fraction of adults who are unaware of their recommendation status is especially large among newly recommended healthy young adults. The universal vaccination recommendations will only be successful if they reach both patients and physicians and lead to changing vaccination practices. The universal nature of the new recommendation simplifies vaccination-related outreach and compliance with government vaccination guidelines considerably, as it does not require any identification of specific recommendation groups based on complex personal or health risk factors.
