Abstract Background Sedentary behavior has been associated with several cardiometabolic risk factors during childhood. However, little is known about the impact of sedentary behavior on the health and eating habits of physically active children and adolescents. Objective To evaluate the association between sedentary behavior and cardiometabolic risk factors and eating habits in physically active children and adolescents. Methods This cross-sectional study was conducted, including 516 physically active children and adolescents (10 to 18 years old; both sexes) enrolled in the […]

Abstract Background Some patients with COVID-19 present myocardial injury. Objective To detect myocardial injury in critically ill paediatric patients, and to compare cardiac involvement between children with severe acute respiratory syndrome (SARS) and children with multisystemic inflammatory syndrome (MIS-C). Methods All COVID-19 children admitted to a referral intensive care unit were prospectively enrolled and had a two-dimensional echocardiogram (2D-TTE) and a cardiac troponin I (cTnI) assay within the first 72 hours. For statistical analysis, two-sided p < 0.05 was considered […]

Abstract Background Cardiometabolic risk has been shown to be inversely associated with cardiorespiratory fitness (CRF) and positively associated with body mass index (BMI). Objective Our objective was to analyze the association of cardiometabolic risk factors with combined BMI and CRF in schoolchildren from a city in southern Brazil. Methods Cross-sectional study with a sample of 1252 schoolchildren aged seven to 17 years. Total cholesterol (TC), HDL-c, LDL-c, triglycerides (TG), systolic (SBP) and diastolic blood pressure (DBP) were evaluated. CRF and […]

Abstract Background: Arterial stiffness is an important predictor factor of aortopathy and myocardial remodeling in patients with a bicuspid aortic valve and it might be increased in childhood. Objective: To assess the arterial stiffness and left ventricular myocardial function in children with a well-functioning bicuspid aortic valve. Methods: Forty-four children with a bicuspid aortic valve and 41 healthy peers with a tricuspid aortic valve were included in this case-control study. Diameters and the related z-scores of the aortic root and […]

Introduction Mutations in the SCN5A gene, encoding the cardiac Na+channel, can result in several life-threatening arrhythmias. These mutations have proven to be causative for inherited and primarily electrical diseases, including Brugada Syndrome (BrS), Long QT Syndrome, and other cardiac conduction disturbances., BrS, the most reported condition in this group of disorders, has typically been described in adult populations and related to approximately 20% of all sudden deaths (SD) in patients with apparently normal hearts.– Therefore, few reports have shown significant […]

Abstract Background COVID-19 pandemic represents a huge burden to the health system in the world. Although pediatric COVID-19 patients have been relatively spared compared with adults, recent reports showed an increasing number of critically ill patients with multisystemic inflammatory syndrome in children (MIS-c), with marked cardiovascular impairment. Nevertheless, little is known about the relationship between cardiac abnormalities and inflammatory and coagulation biomarkers. Objectives to investigate echocardiographic abnormalities in pediatric patients with COVID-19 admitted to tertiary hospital. Methods this was a […]

Abstract Background: Evidence points to anthropometric and fitness variables as associated factors with children’s blood pressure. Analysing these factors in a single context is a relevant possibility of identifying the weight that each factor can present for the development of arterial hypertension. Objective: Identify the possible associations between anthropometric measurements, body composition, moderate-vigorous physical activity (MVPA) and cardiorespiratory fitness (CRF) with blood pressure in children. Methods: Correlational study with a quantitative approach. Sample: 215 schoolchildren aged 6-12 years selected by […]
