ABSTRACT
RESUMO: A prevenção primordial é definida como a prevenção inicial de fatores de risco, por meio da adoção de comportamentos mais saudáveis. Dentro desse conceito, a American Heart Association (AHA) definiu sete métricas, baseadas em evidências, para se alcançar uma saúde cardiovascular (SCV) ideal. O objetivo deste trabalho foi avaliar a prevalência de SCV na população brasileira, segundo sexo, faixa etária e região de moradia, utilizando os dados da última Pesquisa Nacional de Saúde (PNS), de 2013. Foram avaliados, como preconizado pela AHA, de forma conjunta (número de fatores) e isolada, quatro fatores comportamentais (tabagismo, atividade física, índice de massa corporal e dieta) e três biológicos (pressão arterial, glicemia e níveis de colesterol). A população brasileira atingiu prevalências menores de 1%, de sete fatores em nível ideal. Isoladamente, 3,2% da população apresentaram a dieta em nível ideal, seguido da atividade física (23,6%) e índice de massa corporal (43,7%). A população entre 18 e 35 anos apresentou a maior prevalência de número de métricas conjuntas em nível ideal (0,5%), valor também atingido pela população geral da Região Norte. Os resultados indicam que devem ser realizados ainda maiores esforços por meio de políticas públicas de prevenção primordial para atingir metas adequadas de SCV na população brasileira.
ABSTRACT: Primordial prevention is defined as the initial prevention of risk factors, through the adoption of healthier behaviors. Within this concept, the American Heart Association (AHA) has defined seven metrics, based on evidence, to achieve ideal cardiovascular health. The aim of this study was to evaluate the prevalence of cardiovascular health in the Brazilian population, according to sex, age, and region of residence, using data from the latest National Health Survey (2013). We assessed the risk factors, as recommended by the AHA, combined (number of factors) and individually: four behavioral (smoking, physical activity, body mass index and diet) and three biological factors (blood pressure, blood glucose and cholesterol levels). The Brazilian population has reached very low prevalence (1%), for the sum of 7 factors in ideal level. Individually, 3.2% of the population consumed ideal diet, followed by physical activity (23.6%) and body mass index (43.7%). The subjects aged between 18 and 35 years showed higher prevalence of metrics combined at the optimal levels (0.5%), which was also reached by the population of the Northern region. These results indicate that greater efforts are urgent by public policies at the level of primordial prevention in order to achieve appropriate targets of cardiovascular health in the Brazilian population.

To determine whether adiponectin may have synergistic effects in combination with the proinflammatory cytokine interleukin (IL)-1beta regarding the production of proinflammatory mediators during arthritic joint inflammation, synovial cells from rheumatoid arthritis (RA) patients were treated with adiponectin, IL-1beta, and their combination for 24 h. Culture supernatant was collected and analyzed by enzyme-linked immunosorbent assay for levels of IL-6, IL-8, prostaglandin E2 (PGE2), vascular endothelial growth factor (VEGF), and matrix metalloproteinases (MMPs). Adiponectin-mediated intracellular signaling pathways were investigated to elucidate the molecular mechanisms underlying their synergy. The association of proinflammatory mediators with adiponectin was investigated in the synovial fluid of arthritis patients. Adiponectin functioned synergistically with IL-1beta to activate IL-6, IL-8, and PGE2 expression in RA fibroblast-like synoviocytes; Levels of VEGF, MMP-1, and MMP-13 were not synergistically stimulated. Adiponectin and IL-1beta each increased the expression of both adiponectin receptor 1 and IL-1 receptor 1. However, adiponectin and IL-1beta did not synergistically support the degradation of IkappaB-alpha or the nuclear translocation of NF-kappaB. Synergistically increased gene expression was significantly inhibited by MG132, an NF-kappaB inhibitor. Supporting the in vitro results, IL-6 and IL-8 levels were positively associated with adiponectin in synovial joint fluid from patients with RA, but not osteoarthritis (OA). In conclusion, adiponectin and IL-1beta may synergistically stimulate the production of proinflammatory mediators through unknown signaling pathways during arthritic joint inflammation. Adiponectin may be more important to the pathogenesis of RA than previously thought.

Gráficos com demonstração das curvas ângulo-tempo das articulações dos membros dos eqüinos foram avaliados por meio da análise de imagens digitalizadas tomadas de 10 cavalos e 13 éguas da raça Mangalarga Marchador. Foram utilizados marcadores reflexivos adesivos colocados em 19 pontos articulares dos eqüinos, procedendo-se à filmagem com freqüência de 250 quadros por segundo e utilizando-se o aplicativo Simi-motion 3D 6.0 para digitalização e análise das imagens. A utilização dos marcadores reflexivos adesivos constituiu boa metodologia para análise dos movimentos dos segmentos ósseos dos eqüinos. Os resultados observados indicam haver, durante a locomoção dos eqüinos marchadores brasileiros, comportamento similar das articulações quando comparados com eqüinos de sela europeus, apresentando mesmo padrão das curvas de ângulo-tempo e não havendo grandes diferenças entre os pontos máximos de flexão e extensão.
Images of 10 horses and 13 mares of Mangalarga Marchador breed were taken and digitalized to analyze the joint angle-time curves. Reflexives and adhesives markers were glued on 19 articulations points of the hindlimbs and forelimbs of the horses. The images were taken at 250 frames per second and the digitalization and analysis were made using a Simi-motion 3D 6.0 software. The results demonstrated that the methodology using reflexives and adhesives markers was efficient to make analyses of the bone segment movements of the horses. This study concluded that the Brazilian gaited horses have a similar angle-joint curve as the European warmblood horses and there are no great differences of the maximum extension and flexion points.
