BACKGROUND Previous reports have suggested the occurrence of cardiac conduction disorders and permanent pacemaker (PPM) requirement after transcatheter aortic valve implantation (TAVI). Based on a single-center experience, we aim to assess the incidence of postprocedural conduction disorders, need for PPM, and its determinants after TAVI with a(More)
BACKGROUND The purpose of this study was to analyze the relation between body mass index (BMI), Cardiorespiratory Fitness (CRF), and levels of physical activity (PA) from sedentary to very vigorous intensities, measured by accelerometry, in students from a middle and high school. METHODS This cross-sectional study included 111 children and adolescents,(More)
OBJECTIVE The purpose of this study was to assess the associations and impact of increased meal frequency, physical activity and 'skipping' breakfast on obesity levels in a sample of urban adolescents, aged 13-17 years old, from Porto, Portugal. METHODS Overweight and obesity were defined according to age- and sex-specific BMI cut-points. Daily meal(More)
BACKGROUND A permanent pacemaker (PPM) implantation is common after transcatheter aortic valve implantation (TAVI). We sought to evaluate requirements of pacing and incidence of pacemaker dependency during the first year after TAVI. METHODS From August 2007 until May 2011, 65 patients underwent TAVI with self-expandable prosthesis. Five patients paced at(More)
BACKGROUND Treatment-resistant major depressive disorder (MDD) is a complex condition, with very low remission rates. Physical exercise has been used, with some encouraging results, as an alternative therapy in other depressive disorders. This study assessed the impact on depression and functioning parameters of a moderate intensity exercise program, as an(More)
BACKGROUND Elevated blood pressure (BP) has been reported in young people and seems to be associated with body mass index (BMI) and reduced physical activity (PA). AIM This study sought to analyse the association of BP with BMI, PA intensity patterns and cardiorespiratory fitness (CRF) in youth. SUBJECTS AND METHODS A cross-sectional study was carried(More)
The aims of this cross-sectional study were 1) to estimate changes in body composition and cardiorespiratory fitness across stages of pubertal maturation, and 2) to describe the relationship between maturity status and body fatness, regional fat distribution, and cardiorespiratory fitness. The sample consisted of 494 children (254 males, 240 females), 8-16(More)
Modifiable cardiovascular risk factors that increase the risk for cardiovascular diseases (CVD) in adult populations have also been observed in pediatric populations. Childhood and adolescence obesity has been strongly implicated in the clustering of risk factors. The aims of the present study were 1) to examine whether clustering of CVD risk factors,(More)
OBJECTIVE The aims of this study were (1) to assess the relationships between transport to and from school (active vs. passive), sedentary behaviours, measures of socio-economic position and perceived environmental variables, and (2) to determine which, if any, variables were predictors of active transportation. METHODS The sample comprised 705 girls with(More)
OBJECTIVE The purpose of this study was to examine the relationship between sexual maturation (SM), and the prevalence of overweight among boys and girls. SUBJECTS AND METHODS The sample of this cross-sectional study included 819 children and adolescents (382 boys and 437 girls), aged 10-15 years old randomly selected from 30 schools in the Porto region.(More)
