    O presente estudo teve como objetivo analisar os contributos das intervenções de enfermeiras de Cuidados de Saúde Primários, com primíparas, na promoção do aleitamento materno. Trata-se de um desenho quase-experimental, longitudinal, com amostra de 151 primíparas, com menos de 28 semanas de gravidez, entre 15 de outubro de 2007 e 29 de fevereiro de 2008, com filhos vivos aos seis meses após o parto. A quase totalidade das mulheres iniciou o aleitamento materno, verificando-se quebra acentuada da prevalência até os seis meses. A duração média do aleitamento materno foi 123,8±68,9 dias. A intervenção que se iniciou no pré-parto e se prolongou para o pós-parto, com diversidade de estratégias (consulta individual; curso de preparação para a parentalidade/parto e visita domiciliária) e contextos de intervenção (serviços de saúde e domicílio), teve efeitos significativos na duração do aleitamento materno, não se verificando na prevalência.This study aimed to analyze the contributions of the Primary Healthcare nursing interventions, with primiparae in the promotion of breastfeeding. This is a quasi-experimental, longitudinal study, with a sample consisting of 151 primiparae, who had less than 28 weeks of pregnancy, with the child living for at least six months after the birth, performed between 15 October 2007 and 29 February 2008. Almost all the women initiated breastfeeding, with a sharp decline verified in the prevalence at six months. The mean duration of breastfeeding was 123.8±68.9 days. The intervention that began in the prepartum and continued into the postpartum period, using various strategies (individual consultation, preparation courses for parenting/childbirth, and domicile visits) and intervention contexts (health services and domicile) had significant effects on the duration of breastfeeding, which was not verified in the prevalence.info:eu-repo/semantics/publishedVersio

    <p>Abstract</p> <p>Background</p> <p>Children with physical disabilities may have an increased risk for obesity and obesity might be a risk factor for inflammatory arthritis. The aims of this study were: to determine the prevalence of obesity in children and adolescents with juvenile idiopathic arthritis (JIA), and to examine the association between obesity and disease activity in this population.</p> <p>Findings</p> <p>A cross-sectional analysis of all patients with JIA attending a pediatric rheumatology clinic, between October 2009 and September 2010, was performed. A linear regression model was used to explore the association between obesity and disease activity in patients with JIA. A total of 154 subjects were included in the analysis; median age was 10.6 years, 61% were female, and 88% were white. Obesity was found in 18%, 12% were overweight, and 3% were underweight. There was no association between obesity and JADAS-27 (Juvenile Arthritis Disease Activity Score 27), physician's assessment of disease activity, parent's assessment of child's well-being, erythrocyte sedimentation rate, number of active joints, or C-reactive protein (p-value range 0.10 to 0.95).</p> <p>Conclusions</p> <p>Although 18% of patients with JIA were obese, we did not find an association between obesity and disease activity. As obesity confers an additional health risk in children with arthritis, addressing this co-morbidity should be a health priority in patients with JIA. Future studies are necessary to further explore potential associations between obesity, development of JIA, and disease activity.</p

    Fear expression is suppressed by tyrosine administration

    Animal studies have demonstrated that catecholamines regulate several aspects of fear conditioning. In humans, however, pharmacological manipulations of the catecholaminergic system have been scarce, and their primary focus has been to interfering with catecholaminergic activity after fear acquisition or expression had taken place, using L-Dopa, primarily, as catecholaminergic precursor. Here, we sought to determine if putative increases in presynaptic dopamine and norepinephrine by tyrosine administered before conditioning could affect fear expression. Electrodermal activity (EDA) of 46 healthy participants (24 placebo, 22 tyrosine) was measured in a fear instructed task. Results showed that tyrosine abolished fear expression compared to placebo. Importantly, tyrosine did not affect EDA responses to the aversive stimulus (UCS) or alter participants' mood. Therefore, the effect of tyrosine on fear expression cannot be attributed to these factors. Taken together, these findings provide evidence that the catecholaminergic system influences fear expression in humans
