    OBJECTIVE: A low circulating level of bilirubin is associated with increased cardiovascular risk. As statins can stimulate heme oxygenase-1 (HO-1), which increases bilirubin production, we investigated whether statins in routine use increase total bilirubin levels in subjects at high cardiovascular risk. METHODS: Data from 3290 subjects with self-reported history of hypercholesterolemia, diabetes, or cardiovascular diseases in the United States National Health and Nutrition Examination Survey (NHANES) 1999-2008 were analyzed. RESULTS: Subjects taking statins (n = 1156) had lower total bilirubin levels than those not taking any lipid-lowering medication (n = 2134) after adjusting for age, sex, race/ethnicity, and survey period (adjusted mean = 0.699 vs 0.729 mg/dl respectively, P=0.001). The association remained significant after adjusting for more covariates (P = 0.002), but was attenuated after further adjusting for glycosylated hemoglobin, insulin resistance index, and low-density lipoprotein (LDL) cholesterol (P = 0.043). The use of lovastatin, rosuvastatin, and cerivastatin was associated with lower total bilirubin levels in the full adjustment model (P < 0.05). CONCLUSION: The use of statins was associated unexpectedly with lower total bilirubin levels. This could be explained at least partly by the effect of statins on glycemia and LDL cholesterol. Our results do not suggest that the anti-oxidant and anti-inflammatory effects of statins are due to HO-1 induction and increased serum bilirubin levels.postprin

    RESUMO HOFFMANN, Catharina. Acolhimento na Atenção Básica: navegações e mergulhos nos discursos e práticas produzidos no cotidiano de uma Unidade de Saúde da Família. Orientadora: Profa. Dra. Maristela Dalbello Araújo. Vitória/ES: PPGPSI/UFES, 2009. 167f. Dissertação de Mestrado. Esta pesquisa abrange os processos de produção de saúde, tendo como objeto de estudo os discursos e práticas de saúde relacionados ao acolhimento. O contexto de análise é a Atenção Básica do município de Vitória/ES e o campo de pesquisa, o cotidiano da Unidade de Saúde da Família da Ilha do Príncipe. O estudo utilizou como referência os aportes teóricos da Análise Institucional e da Saúde Coletiva. Buscou-se analisar o modo como os trabalhadores fazem acolhimento no cotidiano do serviço, além de escutar as concepções e os discursos produzidos a respeito, na relação com suas práticas cotidianas, o que inclui os processos de trabalho e as interações com os usuários. Para isso, utilizou-se a Cartografia como estratégia metodológica. Os dados foram produzidos no período de fevereiro a setembro de 2008, por meio de observação, diário de campo e entrevistas realizadas com usuários e trabalhadores da USF. Os resultados produzidos expressam que o processo de trabalho e sua gestão são fragmentados e burocratizantes. Há intenção dos trabalhadores de rever os processos de trabalho, entretanto, isto encontra obstáculos na prática. No tocante ao acolhimento, a exigência que os trabalhadores sofrem para que atendam a uma certa produtividade é um aspecto que compromete a qualidade da relação entre as equipes e destas com o usuário, afetando o atendimento às necessidades destes e a própria oferta de ações de saúde. As necessidades que os trabalhadores esperam acolher estão circunscritas à doença ou sintoma manifesto fisicamente. Demonstrou-se que ir ao serviço para conversar constitui-se em uma demanda valorizada pelos usuários, sendo acolhida por alguns trabalhadores. Evidenciou-se que a comunicação nas equipes é restrita às discussões de questões administrativas e procedimentos. A hierarquização entre os níveis de formação contribui para entender o acolhimento como uma atividade ou procedimento que é atribuição de uma categoria específica (auxiliares de enfermagem), a qual supõe-se, tem capacidade técnica para fazê-lo no ato de recepção do usuário. Constatou-se que as ações de saúde não são pactuadas com os usuários, de modo que o PSF não garante o acolhimento. Porém, os tensionamentos nas relações cotidianas entre trabalhador e usuário favorecem a problematização do acolhimento como ação que pode ultrapassar a recepção. Fica evidente a necessidade de reorganização dos processos de trabalho e de se engendrar subjetividades por uma humanização que valorize os processos de singularização, de modo a se promover uma real democracia no acesso à saúde, na qualidade da assistência e na garantia dos princípios do SUS. Palavras-chave: acolhimento; processos de trabalho em saúde; produção de subjetividade; relação trabalhador-usuário

    The imperialist claws of MetaCapitalism

    Get PDF
    The information and industrial revolutions are so different and yet similar. Both enjoyed the emergence of accounting measurement and management techniques which privileged the efficient allocation of resources as the principal imperative to a firm\u27s participation in a free market economy. MetaCapitalism is one such corporate change strategy which promised untold wealth and unprecedented growth, and under that guise a predatory Darwinistic corporate strategy was implemented. Fundamentally, it promotes extreme outsourcing and downsizing of human capital, de-capitalisation of all non-core capital assets and the diminished role of the State in the global free market economy. Yet the most disturbing aspect is its complete and total disregard for even the slightest social or public policy implications. Essentially then, its most salient danger is an unmistakable endorsement of a fundamentalist brand of value free, reckless capitalism that is ultimately detrimental not only to the long-term business interest, but human as well. One of the main findings of evaluating the Fortune 100 companies\u27 performance in implementing MetaCapitalism was the resulting monopolies. Lenin described monopolies as essential to imperialism which is the highest stage of capitalism. The parallels between the resulting monopolies under MetaCapitalism, and what Lenin described as the final stage of Capitalism are poignant. I would like to draw upon those parallels in the hope that earlier work might enlighten our understanding and inform our critique of MetaCapiatlism

    Obesity-induced liver inflammation can drive insulin resistance. HDL has anti-inflammatory properties, so we hypothesized that low levels of HDL would perpetuate inflammatory responses in the liver and that HDL treatment would suppress liver inflammation and insulin resistance. The aim of this study was to investigate the effects of lipid-free apoAI on hepatic inflammation and insulin resistance in mice. We also investigated apoAI as a component of reconstituted HDLs (rHDLs) in hepatocytes to confirm results we observed in vivo. To test our hypothesis, C57BL/6 mice were fed a high-fat diet (HFD) for 16 weeks and administered either saline or lipid-free apoAI. Injections of lipid-free apoAI twice a week for 2 or 4 weeks with lipid-free apoAI resulted in: i) improved insulin sensitivity associated with decreased systemic and hepatic inflammation; ii) suppression of hepatic mRNA expression for key transcriptional regulators of lipogenic gene expression; and iii) suppression of nuclear factor κB (NF-κB) activation. Human hepatoma HuH-7 cells exposed to rHDLs showed suppressed TNFα-induced NF-κB activation, correlating with decreased NF-κB target gene expression. We conclude that apoAI suppresses liver inflammation in HFD mice and improves insulin resistance via a mechanism that involves a downregulation of NF-κB activation.

    Pre-Fibrillar α-Synuclein Mutants Cause Parkinson's Disease-Like Non-Motor Symptoms in Drosophila

    Get PDF
    Parkinson's disease (PD) is linked to the formation of insoluble fibrillar aggregates of the presynaptic protein α-Synuclein (αS) in neurons. The appearance of such aggregates coincides with severe motor deficits in human patients. These deficits are often preceded by non-motor symptoms such as sleep-related problems in the patients. PD-like motor deficits can be recapitulated in model organisms such as Drosophila melanogaster when αS is pan-neurally expressed. Interestingly, both these deficits are more severe when αS mutants with reduced aggregation properties are expressed in flies. This indicates that that αS aggregation is not the primary cause of the PD-like motor symptoms. Here we describe a model for PD in Drosophila which utilizes the targeted expression of αS mutants in a subset of dopadecarboxylase expressing serotonergic and dopaminergic (DA) neurons. Our results show that targeted expression of pre-fibrillar αS mutants not only recapitulates PD-like motor symptoms but also the preceding non-motor symptoms such as an abnormal sleep-like behavior, altered locomotor activity and abnormal circadian periodicity. Further, the results suggest that the observed non-motor symptoms in flies are caused by an early impairment of neuronal functions rather than by the loss of neurons due to cell death

    How does one become spiritual? The Spiritual Modeling Inventory of Life Environments (SMILE)

    We report psychometric properties, correlates and underlying theory of the Spiritual Modeling Index of Life Environments (SMILE), a measure of perceptions of spiritual models, defined as everyday and prominent people who have functioned for respondents as exemplars of spiritual qualities, such as compassion, self-control, or faith. Demographic, spiritual, and personality correlates were examined in an ethnically diverse sample of college students from California, Connecticut, and Tennessee (N=1010). A summary measure of model influence was constructed from perceived models within family, school, religious organization, and among prominent individuals from both tradition and media. The SMILE, based on concepts from Bandura\u27s (1986) Social Cognitive Theory, was well-received by respondents. The summary measure demonstrated good 7-week test/retest reliability (r=.83); patterns of correlation supporting convergent, divergent, and criterion-related validity; demographic differences in expected directions; and substantial individual heterogeneity. Implications are discussed for further research and for pastoral, educational, and health-focused interventions

    Polymorphisms in the P2X7 receptor gene are associated with low lumbar spine bone mineral density and accelerated bone loss in post-menopausal women

    The P2X7 receptor gene (P2RX7) is highly polymorphic with five previously described loss-of-function (LOF) single-nucleotide polymorphisms (SNP; c.151+1G>T, c.946G>A, c.1096C>G, c.1513A>C and c.1729T>A) and one gain-of-function SNP (c.489C>T). The purpose of this study was to determine whether the functional P2RX7 SNPs are associated with lumbar spine (LS) bone mineral density (BMD), a key determinant of vertebral fracture risk, in post-menopausal women. We genotyped 506 post-menopausal women from the Aberdeen Prospective Osteoporosis Screening Study (APOSS) for the above SNPs. Lumbar spine BMD was measured at baseline and at 6–7 year follow-up. P2RX7 genotyping was performed by homogeneous mass extension. We found association of c.946A (p.Arg307Gln) with lower LS-BMD at baseline (P=0.004, β=−0.12) and follow-up (P=0.002, β=−0.13). Further analysis showed that a combined group of subjects who had LOF SNPs (n=48) had nearly ninefold greater annualised percent change in LS-BMD than subjects who were wild type at the six SNP positions (n=84; rate of loss=−0.94%/year and −0.11%/year, respectively, P=0.0005, unpaired t-test). This is the first report that describes association of the c.946A (p.Arg307Gln) LOF SNP with low LS-BMD, and that other LOF SNPs, which result in reduced or no function of the P2X7 receptor, may contribute to accelerated bone loss. Certain polymorphic variants of P2RX7 may identify women at greater risk of developing osteoporosis

    Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

    Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
