Sympathetic neural activity, metabolic parameters and cardiorespiratory fitness in obese youths.
2017
OBJECTIVE: The main objective of this cross-sectional study is to assess the cardiac autonomic neural activity in the presence of abnormally increased body weight in youths and its relationship to metabolic risk factors and cardiorespiratory fitness (CRF). METHODS: Sixty-four overweight and obese patients, aged 9-17 years, of both sexes, stratified according to the international BMI cut-off, were enrolled. Continuous ECG was recorded during 15 min in resting conditions, and the heart rate variability (HRV) was measured in the time domain, frequency domain and for nonlinear dynamics. In addition, cardiometabolic risk factors and CRF in effort conditions were assessed. RESULTS: Among the over…
Evidences from Clinical Trials and Use of Antihypertensive Drugs in Children and Adolescents
2019
In adults, when prescribing antihypertensive therapy, decisions regarding the choice of agent can be based upon evidence from clinical trials in large numbers of subjects, many of these having compared one class of agent with another. Whilst increased emphases on conducting drug trials in children and adolescents over the past 25 years have yielded important advances, and have tested the efficacy and safety of the various classes of antihypertensive agents, there remains a general lack of high quality long-term outcome data to guide choice of drug therapy for pediatricians managing HTN. As of today, certain clinical trials in children and adolescents have established the pharmacokinetics, p…
Longitudinal study of DNA methylation during the first 5 years of life
2016
[Background]: Early life epigenetic programming influences adult health outcomes. Moreover, DNA methylation levels have been found to change more rapidly during the first years of life. Our aim was the identification and characterization of the CpG sites that are modified with time during the first years of life. We hypothesize that these DNA methylation changes would lead to the detection of genes that might be epigenetically modulated by environmental factors during early childhood and which, if disturbed, might contribute to susceptibility to diseases later in life. [Methods]: The study of the DNA methylation pattern of 485577 CpG sites was performed on 30 blood samples from 15 subjects,…
Impact of ESH and AAP hypertension guidelines for children and adolescents on office and ambulatory blood pressure-based classifications.
2019
The objective was to assess the differences between the 2016 European Society of Hypertension (ESH) and the 2017 American Academy of Pediatrics (AAP) hypertension (HTN) guidelines in the distribution of office blood pressure (BP) categories as well as in the office and ambulatory BP mismatches.The study included 4940 clinical evaluations performed in 2957 youth (5-18 years) of both sexes. BP and anthropometric parameters were measured following standard conditions. The classification of the BP measurements was normotension, high-normal, stages 1 and 2 HTN, following the criteria of both guidelines. In a subgroup of 2467 participants, 3941 office BP assessment was completed with 24-h ambulat…
Identifying poor cardiorespiratory fitness in overweight and obese children and adolescents by using heart rate variability analysis under resting co…
2020
Background: Childhood obesity, including overweight, continues increasing worldwide affecting health expectancy, quality of life and healthcare expenditure. These subjects have higher probability of suffering or developing cardio metabolic risk factors. Recent studies have revealed cardiorespiratory fitness (CRF) as a valuable clinical parameter to identify these subjects and have even suggested cut-off values. However, evaluating CRF in overweight and obese youth can be difficult to implement, unfriendly and expensive. Objective: Develop a screening tool to identify high-risk subjects in a representative population of those attending overweight/obesity assessment programmes without prior i…
Obesity and cardiovascular risk
2018
: Obesity is a key factor for cardiovascular diseases and complications. Obesity is associated with hypertension, dyslipidemia and type II diabetes, which are the major predictors of cardiovascular disease in the future. It predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke that are the main causes of cardiovascular hospitalization and mortality. As obesity and the cardiovascular effects on the vessels and the heart start early in life, even from childhood, it is important for health policies to prevent obesity very early before the disease manifestation emerge. Key roles in the prevention are strategies to increase physical exercise,…

: Obesity predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke, which are the main causes of cardiovascular hospitalization and mortality. As obesity and the cardiovascular effects on the vessels and the heart start early in life, even from childhood, it is important for health policies to prevent obesity very early before the disease manifestation emerge. Key roles in the prevention are strategies to increase physical exercise, reduce body weight and to prevent or treat hypertension, lipids disorders and diabetes earlier and efficiently to prevent cardiovascular complications.
Relationship between body composition and postural control in prepubertal overweight/obese children: A cross-sectional study
2017
Abstract Background Excess body weight during childhood causes reduced motor functionality and problems in postural control, a negative influence which has been reported in the literature. Nevertheless, no information regarding the effect of body composition on the postural control of overweight and obese children is available. The objective of this study was therefore to establish these relationships. Methods A cross-sectional design was used to establish relationships between body composition and postural control variables obtained in bipedal eyes-open and eyes-closed conditions in twenty-two children. Centre of pressure signals were analysed in the temporal and frequency domains. Pearson…
Determinants of Cardiometabolic Risk Factors in the First Decade of Life
2017
The present prospective study assessed the association of birth weight (BW) and growth pattern on cardiometabolic risk factors in a cohort followed from birth to 10 years of age. One hundred and forty-five subjects (73 girls) who fulfilled the inclusion criteria and had all their data recorded at birth and at 5 years were enrolled. Of these, 100 (52 girls) also recorded data at 10 years. Anthropometric measurements, office and 24-hour blood pressure, and metabolic parameters were obtained. At 5 years, both BW and current weight were determinants of blood pressure and metabolic parameters; however, as the subjects got older, the impact of body size increased. Higher BW and maternal obesity i…
Longitudinal genome-wide DNA methylation analysis uncovers persistent early-life DNA methylation changes
2019
[Background] Early life is a period of drastic epigenetic remodeling in which the epigenome is especially sensitive to extrinsic and intrinsic influence. However, the epigenome-wide dynamics of the DNA methylation changes that occur during this period have not been sufficiently characterized in longitudinal studies.
Uric acid is linked to cardiometabolic risk factors in overweight and obese youths.
2018
OBJECTIVE Observational studies have indicated that high levels of serum uric acid are associated with the risk of cardiovascular disease. The aim of the present study is to investigate the association of uric acid with individual cardiometabolic risk factors, as well as their degree of clustering, in overweight and moderate obese youth. METHODS Three hundred and thirty-three Caucasians of both sexes (149 women), from 5-18 years of age from those who underwent an assessment of overweight/obesity. Anthropometric parameters, office and 24-h blood pressure measurements and metabolic profile, including HDL-cholesterol, triglycerides, insulin, HOMA index and uric acid were assessed. RESULTS Uric…
Gender-related differences in serum uric acid in treated hypertensive patients from central and east European countries: findings from the Blood Pres…
2019
OBJECTIVE: Hyperuricemia has been associated with high blood pressure (BP) values, diabetes mellitus, metabolic syndrome and chronic kidney disease (CKD). In the present study, we assessed the gender-related relationships between serum uric acid (SUA) and cardionephrometabolic variables in central and east European hypertensive patients. METHODS: A total of 3206 treated hypertensive patients with available SUA levels from the BP-CARE study was analyzed. Correlations among SUA, BP values, BP control, diabetes mellitus, metabolic syndrome and CKD were performed according to gender. RESULTS: Twenty-five percent of the whole population showed hyperuricemia (28% in women and 23% in men). These p…
