ABSTRACT
O objetivo deste estudo foi analisar a relação do incentivo parental com o gosto pela prática e a percepção do nível de atividade física (AF) de adolescentes. Trata-se de um estudo descritivo epidemiológico de base escolar. Participaram do estudo 1011 adolescentes. Verificou-se que 90,4% dos adolescentes avaliados gostam de praticar AF e 81,4% se percebem fisicamente ativos. O incentivo parental teve associação com gostar de AF apenas para a variável "a mãe não levar para fazer AF", para o qual, 74,3% dos que gostam de AF a mãe não leva para fazer (p=0,012). Quando comparado a percepção de inatividade física com a de estímulo dos pais para a prática, mais de 70% dos inativos afirmam que sua mãe estimula a ser ativo e cerca de 50% afirmam que o pai estimula a ser ativo. Conclui-se que o incentivo dos pais foi significativamente associado com a percepção do nível de AF.
The aim of this study was to analyze the relationship between parental incentive and taste for practice and the perception of the level of physical activity (PA) of adolescentes. This is a school-based epidemiological descriptive study. 1011 adolescents participated in the study. It was found that 90.4% of the evaluated adolescents like to practice PA and 81, 4% perceive themselves as physically active. The parental incentive was associated with liking PA only for the variable "the mother doesn't take it to do PA", for which, 74.3% of those who like PA, the mother does not take it (p=0.012). When comparing the perception of physical inactivity with the parents' encouragement to practice, more than 70% of the inactive say that their mother encourages them to be active and about 50% say that their father encourages them to be active. It is concluded that parental encouragement was significantly associated with perceived PA level.
ABSTRACT
Considerando o grande interesse observado, os avanços nas técnicas para preservação da fertilidade feminina e levando em conta que a criopreservação de oócitos é uma atraente estratégia para preservação da fertilidade, foi realizada uma revisão sistemática para comparar a criopreservação de oócitos com outros métodos já estabelecidos para este intuito. Foram buscadas referências em dois bancos de dados (Medline e Lilacs), e identificados 869 estudos, mas nenhum deles conseguiu preencher os critérios de inclusão. Ainda há um longo caminho para este método ser incorporado à prática clínica.
Considering the great interest observed; the advancement of techniques to preserve female fertility and that oocyte cryopreservation is an attractive strategy to fertility preservation, this systematic review was conducted in order to compare the cryopreservation of oocytes with other already established methods. References were searched in two databases (Medline and Lilacs). A total of 869 studies were identified, however none of them could compare oocytes cryopreservation with other techniques to preserve female fertility. There is still a long way to go to integrate it into a routine clinical procedure.

The pathophysiological mechanisms linking cardiovascular dysautonomy to mortality are unclear. The aim of this study was to investigate the pattern of 24-h ambulatory blood pressure (BP) monitoring (ABPM) in diabetic patients with cardiovascular autonomic neuropathy (CAN). We evaluated 391 type 2 diabetic patients in a cross-sectional study. Five clinical tests of CAN were performed: heart-rate variation during deep breathing, the Valsalva maneuver, and standing, and BP variation during handgrip and standing. Patients were considered to have initial CAN if one heart-rate test was abnormal or two were borderline, and to have definite or severe CAN if at least two tests were abnormal. Differences between patients with and without CAN were assessed by bivariate tests and ANCOVA. Of the 391 patients, 230 (59%) presented clinical CAN, of whom 53 had definite or severe involvement. Patients with CAN were older, had diabetes of longer duration, and had an equal prevalence of hypertension but used more antihypertensive drugs than those without CAN. On ABPM, patients with definite or severe CAN had higher systolic BP (SBP) and pulse pressures (PP) than those without CAN, particularly in the nighttime (SBP: 128 +/- 18 vs. 117 +/- 16 mmHg, p = 0.007; PP: 58 +/- 13 vs. 50 +/- 11 mmHg, p = 0.003) and early morning (SBP: 140 +/- 18 vs. 131 +/- 17 mmHg, p = 0.05) after adjustment for potential confounders, as well as a higher prevalence of the systolic nondipping pattern (75.5% vs. 50.9%, p = 0.021). In conclusion, type 2 diabetic patients with more severe CAN have higher SBP and PP, especially during the nighttime and early morning, as well as a higher prevalence of nondipping status. This unfavorable 24-h ABPM pattern may contribute to the increased cardiovascular risk of diabetic patients with dysautonomy.
