    A síndrome do impacto do ombro (SIO) se refere a uma combinação de sintomas do ombro, achados do exame e sinais radiológicos atribuíveis à compressão das estruturas ao redor da articulação glenoumeral que ocorrem com a elevação do ombro, essa compressão causa dor e disfunção persistentes.  O diagnóstico de SIO implica um espectro de achados clínicos, não lesão de uma estrutura específica, a dor no ombro Ê altamente prevalente na população em geral, perdendo apenas para a dor lombar. As radiografias simples são desnecessårias para a avaliação inicial de suspeita de SIO, a ultrassonografia geralmente revela o local do impacto e os tendþes envolvidos. As evidências para orientar o gerenciamento do SIO são limitadas, os programas de fisioterapia desenvolvidos e executados adequadamente tratam com eficåcia a maioria dos pacientes.

    Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

    Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

    Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

    A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

    Search for pair production of excited top quarks in the lepton+jets final state

    A search is performed for pair-produced spin-3/2 excited top quarks (t∗tˉ∗t^*\bar{t}^*), each decaying to a top quark and a gluon. The search uses data collected with the CMS detector from pp collisions at a center-of-mass energy of s\sqrt{s}=8 TeV, selecting events that have a single isolated muon or electron, an imbalance in transverse momentum, and at least six jets, of which one must be compatible with originating from the fragmentation of a b quark. The data, corresponding to an integrated luminosity of 19.5 inverse femtobarns, show no significant excess over standard model predictions, and provide a lower limit of 803 GeV at 95% confidence on the mass of the spin-3/2 t* quark in an extension of the Randall-Sundrum model, assuming a 100% branching fraction of its decay into a top quark and a gluon. This is the first search for a spin-3/2 excited top quark performed at the LHC.A search is performed for pair-produced spin-3/2 excited top quarks t ∗ t ¯ ∗ , each decaying to a top quark and a gluon.

    Dispositivo intrauterino de cobre em puÊrperas: grau de satisfação e conhecimento sobre seu uso em pacientes em Belo Horizonte

    Get PDF
    O dispositivo intrauterino de cobre (DIU) Ê um mÊtodo contraceptivo altamente eficaz, não hormonal, e de longa duração reversível, com uma taxa de gravidez inferior a 0,4% no primeiro ano de uso. Entretanto, apenas 1,9% das mulheres em idade reprodutiva utilizam, apesar dos benefícios jå evidenciados. Este trabalho consiste em avaliar o grau de satisfação e conhecimento sobre o DIU de cobre das puÊrperas da Maternidade Santa Casa de Misericórdia de Belo Horizonte. Foi realizado um estudo descritivo transversal, baseado na coleta de dados por meio de questionårios validados, aplicados a uma amostra de 75 mulheres no puerpÊrio imediato na Maternidade Santa Casa de Misericórdia de Belo Horizonte, entre janeiro e março de 2024. A mÊdia de conhecimento apresentada pelas pacientes em um escore de 1 a 5 foi de 3,6 ¹ 1,4. No quesito satisfação, esse escore mÊdio geral foi de 3,8 ¹ 0,6. Os resultados indicam um alto nível de satisfação entre as usuårias, especialmente entre as mais jovens e solteiras, que buscam evitar gestaçþes não planejadas. Entretanto, tambÊm revelam lacunas significativas no conhecimento sobre o mecanismo de ação e possíveis complicaçþes. A diversidade educacional das participantes, com ensino mÊdio completo majoritariamente, destacou a importância da escolaridade na compreensão e adesão ao mÊtodo. Deste modo, conclui-se que, apesar dos benefícios comprovados do DIU de cobre e da alta satisfação, Ê necessårio aprimorar a comunicação, para aumentar o nível de conhecimento sobre este dispositivo, beneficiando a saúde reprodutiva das mulheres e a eficåcia dos programas de planejamento familiar

    Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8  TeV

    Get PDF
    Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel
