Abstract
This study aims to identify the key genes and their regulatory networks by bioinformatics, increasing understanding of childhood obesity. The data comes from the GEO and Immport database. The immune microenvironment was explored in GSE104815. Key genes were identified by intersection of DEGs with the immune gene set. Enrichment analysis revealed gene-related functions and correlation analysis explored the relationship. Regulatory networks were constructed based on miRcode, TarBase and TargetScan databases. GSE29718 was used to validate our findings. Intercellular communication and cell differentiation trends were further explored using single-cell data from GSE153643. Based on our research, the immune microenvironment in the obese group showed higher immune infiltration. We found 962 DEGs and CXCL2 was identified as the key gene. The co-regulatory network of lncRNA-miRNA-mRNA suggested that obtaining TM4SF19-AS1, GUSBP11, AC105020.1, LINC00189, COL4A2-AS2, VIPR1-AS1 and LINC00242 may regulate CXCL2 (r > 0.9 and P < 0.01). Differential expression of CXCL2 was validated in GSE29718 (P < 0.05) and CXCL2 was identified as a biomarker for childhood obesity (AUC = 0.885). GSVA enrichment analysis revealed many pathways of high group obtaining the TNF-α signaling via NF-κB pathway and interferon γ response pathway. In GSE153643, 11 cell types were identified and CXCL2 was highly expressed in monocyte, macrophage, endothelial cell and pericyte. In CXCL2 high expressing macrophages, there was a tendency for cells to polarize toward M1 macrophages (P < 0.05). In summary, we identified CXCL2 as a potential biomarker of childhood obesity. The development of childhood obesity may be associated with the activation of immune infiltration of macrophage M1 polarization by CXCL2 expression.

Abstract
OBJECTIVE Hypertension has become a global medical and public health issue even in childhood. It is well accepted that hypertension is associated with impaired endothelium-dependent vascular reactivity in adult patients. However, there is a lack of data on hypertension-related endothelial dysfunction in hypertensive children. Thus, present study aimed to evaluate the association of primary hypertension in the pediatric population with macro- and microvascular function, and to assess the potential role of oxidative stress in that connection. METHODS Fifty-two children were enrolled in this study; 26 normotensive (NT) and 26 with primary hypertension (HT), both sexes, 9-17 years old. In addition to anthropometric, hemodynamic and biochemical measurements, peripheral microvascular responses to occlusion (postocclusive reactive hyperemia, PORH), local heating (local thermal hyperemia, LTH), iontophoretically applied acetylcholine (AChID) and sodium nitroprusside (SNPID) were evaluated by laser Doppler flowmetry (LDF). Furthermore, brachial artery flow-mediated dilation (FMD) was measured and biomarker of oxidative stress was determined. RESULTS PORH, AChID and LTH were impaired in hypertensive compared to normotensive children, while SNPID did not differ between groups. FMD was decreased in hypertensive compared to normotensive children. Serum concentration of 8-iso-PGF2α was significantly elevated in hypertensive compared to normotensive children. CONCLUSION Even in childhood, primary hypertension is associated with attenuated endothelial function and reduced endothelium-dependent responses to various physiological stimuli. Juvenile hypertension is related to increased level of vascular oxidative stress. All changes are independent of BMI.

Abstract
OBJECTIVE Arterial stiffness is an early and detectable marker of vascular changes leading to atherosclerotic cardiovascular disease (ACVD). Our objective was to compare the effectiveness of different types of exercise in reducing arterial stiffness in children and adolescents. DESIGN A systematic review and network meta-analysis (NMA) was conducted including experimental studies reporting the effects of exercise interventions on pulse wave velocity (PWV) in children and adolescents. DATA SOURCES Cochrane Central Register of Controlled Trials, EMBASE (via Scopus), PubMed (via Medline) and Web of Science from database inception to 25 March 2022. ELIGIBILITY CRITERIA Experimental studies reporting the effects of exercise interventions on PWV in children and adolescents. RESULTS Fourteen studies were included in the NMA, all of them were randomised controlled trials except one quasi-experimental study, with an overall risk of bias of some concern. Regarding PWV reduction, all exercise modalities were more effective than control, with standardised mean difference ranging from -1.93 (95% CI: -2.84 to -1.02) and -1.11 (95% CI: -2.01 to -0.21) for aerobic exercise and high intensity interval training (HIIT), respectively, to -0.59 (95% CI: -1.39 to 0.22) for combined exercise. Only sensorimotor training was not superior to the control group 0.11 (95% CI: -1.10 to 1.32). CONCLUSION Our results support that exercise interventions, especially aerobic exercise or HIIT, can improve arterial stiffness at early ages. The potential to address ACVD early and mitigate long-term consequences via exercise interventions in children and adolescents with higher arterial stiffness requires further investigation.

Abstract
BACKGROUND Youth with cystic fibrosis (CF) and pulmonary exacerbation (PEx) often experience weight loss, then rapid weight gain. Little is known about body composition and its relationship to functional outcomes during this critical period. METHODS Twenty CF youth experiencing PEx were assessed on the day following admission and 7-17 days later at discharge for body mass index (BMI), fat mass index (FMI), lean mass index (LMI), skeletal muscle mass index (SMMI), and functional measures: percent predicted forced expiratory volume in 1 second (FEV1) (ppFEV1), maximal inspiratory and expiratory pressures (MIPs and MEPs), and handgrip strength (HGS). Changes from admission to discharge and correlations among body composition indices and functional measures at both times are reported. RESULTS Upon admission, participant BMI percentile and ppFEV1 varied from 2 to 97 and 29 to 113, respectively. Thirteen had an LMI below the 25th percentile and nine had a percent body fat above the 75th percentile. BMI and FMI increased significantly (p = 0.03, 0.003) during hospitalization. LMI and SMMI did not change. FEV1 and MIPS increased (p = 0.0003, 0.007), independent of weight gain, during treatment. HGS did not improve. CONCLUSIONS Many youth with CF, independent of BMI, frequently carried a small muscle mass and disproportionate fat at the time of PEx. During hospital treatment, weight gain largely represented fat deposition; muscle mass and strength did not improve. A need for trials of interventions designed to augment muscle mass and function, and limit fat mass accretion, at the time of PEx is suggested by these observations.

Eur J Pediatr 2023; 182:203-211. [PMID: 36278997 DOI: 10.1007/s00431-022-04653-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 09/07/2022] [Accepted: 10/06/2022] [Indexed: 01/12/2023]
Abstract
UNLABELLED Incidence of diabetes during pregnancy is increasing worldwide, and intrauterine hyperglycemia exposure may have long-term adverse effects on the cardiovascular health of children. We investigated prospectively the risk of atherosclerosis and carotid intima-media thickness (CIMT) in infants born macrosomic and in infants of diabetic mothers (IDM) at the age of 8-9 years in 2021. A total of 49 infants of diabetic mothers (IDM group) and 13 macrosomic infants (macrosomic group) were included in the study. They were compared with 26 age-matched healthy children with birth weight appropriate for gestational age born to non-diabetic mothers (control group). Anthropometric measurements, atherosclerosis risk factors, and CIMT measurements were performed. There was no significant difference between the groups in terms of age, gender, actual anthropometric measurements, blood pressure measurements, laboratory parameters, or atherosclerosis risk factors. Gestational age was lower in the IDM group (p < 0.001), while birth weight was higher in the macrosomic group (p < 0.001). High-density lipoprotein cholesterol level was lower in the IDM group than the other groups. Duration of exclusive and total breastfeeding was lower in IDM group than in the control group (p < 0.001 for both). Body mass index, skinfold thickness, waist-to-hip ratio, and waist-to-height ratio were higher in those breastfed for less than 6 months in the IDM group. The CIMT values were statistically higher in IDM [0.43 ± 0.047 (0.34-0.60)] and macrosomic [0.40 ± 0.055 (0.33-0.50)] groups than control group [0.34 ± 0.047 (0.26-0.45)]. CONCLUSION CIMT values were higher in IDM and macrosomic groups at 8-9 years old age compared to children born with normal birth weight. This indicates intrauterine exposure in both groups. And also, breastfeeding seems very important for IDMs. WHAT IS KNOWN • Intrauterine hyperglycemia exposure has long-term adverse effects on the cardiovascular health of children. • Infants of diabetic mothers have higher carotid artery intima-media thickness at birth. WHAT IS NEW • Both infants of diabetic mothers and infants with macrosomia have increased carotid artery intima-media thickness at the age of 8-9 years. • Duration of breast feeding is important especially in infants of diabetic mothers as body mass index, skinfold thickness, waist to hip and height ratio were higher in those breastfed less than 6 months.

The Impact of Obesity on C1q/TNF-Related Protein-9 Expression and Endothelial Function following Acute High-Intensity Interval Exercise vs. Continuous Moderate-Intensity Exercise. BIOLOGY 2022; 11:biology11111667.

Abstract
C1q-TNF-related protein-9 (CTRP9) increases endothelial nitric oxide synthase and reduces vasoconstrictors. There is limited information regarding exercise-mediated CTRP9 in obesity. The purpose of this study was to compare high-intensity interval exercise (HIIE) and continuous moderate-intensity exercise (CME) on the CTRP9 response and an indicator of endothelial function (FMD) in obese participants. Sixteen young male participants (9 obese and 7 normal-weight) participated in a counterbalanced and caloric equated experiment: HIIE (30 min, 4 intervals of 4 min at 80–90% of VO2 max with 3 min rest between intervals) and CME (38 min at 50–60% VO2 max). Serum CTRP9 and FMD were measured prior to, immediately following exercise, and 1 h and 2 h into recovery. CTRP9 was significantly increased immediately following acute HIIE and CME in both groups (p = 0.003). There was a greater CME-induced FMD response at 2 h into recovery in obese participants (p = 0.009). A positive correlation between CTRP9 and FMD percent change was observed in response to acute CME when combined with both obese and normal-weight participants (r = 0.589, p = 0.016). The novel results from this study provide a foundation for additional examination of the mechanisms of exercise-mediated CTRP9 on endothelial function in individuals with obesity.

Abstract
IntroductionChildhood obesity is a chronic disease that requires multidisciplinary and specialist intervention to address its complex pathophysiology, though access to treatment is limited globally. Evaluating the impact of evidence-based interventions implemented in real-world clinical settings is essential, in order to increase the translation of research into practice and enhance child health outcomes. In Ireland, the National Model of Care for Obesity highlighted the need to develop and improve healthcare services for children and adolescents with obesity.AimsThis study aims to evaluate the impact of a family-based, Tier 3 multi-disciplinary child and adolescent obesity outpatient service (www.w82go.ie) on standardized body mass index (BMI-SDS).MethodsFollowing referral by pediatricians, patients were assessed by a pediatric multidisciplinary team (physiotherapist, dietician, and psychologist) and personalized obesity treatment plans were developed. Anthropometric and demographic information were recorded at baseline and final visit. Descriptive statistics were used to explore distribution, central tendency and variation in the demographic data, change in BMI-SDS over time was assessed using a t-test, and multiple linear regression analysis was used to investigate the association of demographic factors on the change in BMI-SDS.ResultsThe overall mean BMI-SDS reduction across the whole cohort (n = 692) was −0.17 (95% CI = −0.20, −0.13; P < 0.001). Younger age at admission and longer duration of treatment were associated with greater BMI-SDS reduction but there was no significant association between change in BMI-SDS and any of the other parameters (deprivation score, treatment type, sex, obesity category at admission or presence of comorbid condition).ConclusionEngagement in a specialist Tier 3 pediatric obesity service was associated with reductions in BMI-SDS in children and adolescents with obesity.

Abstract
This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.

Abstract
According to the World Health Organization obesity is the result of an energy imbalance between calories assumed and expended and over the past 30 years its incidence has dramatically increased. Recently, the problem of obesity has drastically increased also in childhood, assuming a social relevance. Childhood obesity, in fact, increases the possibility to be obese in adulthood, representing a risk for cardiovascular morbidity and mortality. Aim of this review was to carry out a revision of the literature on childhood obesity focusing on natriuretic peptides (NPs) and in particular on the role of C-type natriuretic peptide (CNP). In obesity NPs play a fundamental role in the regulation of body weight and energy metabolism. Data on plasma CNP levels in children are scarce. The review of the literature relating to the role of CNP in adolescents showed a progressive reduction in the CNP plasma levels in overweight/obese adolescents compared to normal-weight subjects, as previously observed in obese adults, as well as a different modulation in CNP mRNA expression. An independent association between CNP levels and obesity as well as a significant association with the endothelial dysfunction index was reported, indicating that the peptide could play a very important role as a marker of risk of developing obesity. The results of these studies indicate the importance of adopting healthy lifestyles to improve glucometabolic control as well as to provide the rationale for designing and developing new drugs to modulate the NPs system.

Abstract
OBJECTIVE Obesity is a well-known risk factor for coronary heart disease (CHD), but there is little evidence on the effect of long-term trajectories of body mass index (BMI) over the life course. By using repeated assessments, the aim was to study the risk of CHD in adults during 38 years in different trajectories of BMI. METHODS A sample of 2129 men and women, aged 20-59 years at baseline, took part in four repeated interviews between 1980 and 2005. Data on BMI, medical history, lifestyle and socioeconomy were collected. Based on the World Health Organization categories of BMI, life course trajectories of stable normal weight, stable overweight, stable obesity, increasing BMI and fluctuating BMI were created. The individuals were followed through national registers for first hospitalization of CHD (389 events) until the end of 2017, and Hazard Ratios (HRs) were calculated, adjusted for age, sex, socioeconomic factors, lifestyle factors and metabolic comorbidities. RESULTS Stable normal weight in all assessments was the reference group. Those who had an increase in BMI from normal weight in the first assessment to overweight or obesity in later assessments had no increased risk of CHD, HR 1.04 (95% CI: 0.70-1.53). The HR for individuals with fluctuating BMI was 1.25 (0.97-1.61), for stable overweight 1.43 (1.03-1.98), for stable obesity 1.50 (0.92-2.55), and for stable overweight or obesity 1.45 (1.07-1.97), after full adjustments. CONCLUSION Having a stable overweight or obesity throughout adult life was associated with increased CHD risk but changing from normal weight at baseline to overweight or obesity was not associated with increased CHD risk. Prevention of obesity early in life may be particularly important to reduce CHD risk.

Abstract
This study aimed to establish standard reference values for soluble thrombomodulin in healthy prepubertal school-aged children and elucidate the relationship between soluble thrombomodulin levels and obesity, metabolic syndrome-associated indices, and other markers of vascular endothelial damage. The participants in this study were healthy Japanese children aged 9-10 years (315 boys and 267 girls). Blood tests for soluble thrombomodulin, leptin, fibrinogen, and general biochemical markers were performed, and the mean and 10th, 50th, and 90th percentiles for each marker were determined. Participants were divided into two groups based on their waist circumference (≥75 vs. <75 cm), and each parameter was compared between the two groups. Analyses were performed to compare subgroups with different numbers of risk factors for cardiovascular disease (CVD). We found that as CVD risk factors accumulated, the levels of total cholesterol, alanine aminotransferase, uric acid, soluble thrombomodulin, fibrinogen, and leptin were significantly elevated, whereas the level of high-density lipoprotein cholesterol significantly decreased. We determined reference values for soluble thrombomodulin in prepubertal children, and our results suggest that soluble thrombomodulin levels contribute to the latent progress of arteriosclerosis from childhood.

Abstract
BACKGROUND AND OBJECTIVE This study aimed to investigate if childhood primary snoring (PS) was associated with adverse cardiovascular outcomes at 5-year follow-up. METHODS This was a prospective matched cohort study. Subjects were recruited from a hospital-based cohort established from years 2006 to 2012 and they were aged 6-18 years at baseline. Each subject with PS was gender, age and BMI z-score matched with a control who had normal sleep study (obstructive apnoea-hypopnoea index [OAHI] < 1/h) and without habitual snoring (<3 nights/week) at baseline. All subjects underwent measurements of flow-mediated dilation (FMD) and carotid intima-media thickness (cIMT) and sleep study at baseline and follow-up visits. Twenty-four hour ambulatory blood pressure (ABP) was also recorded at follow-up. RESULTS Fifty-five case-control pairs were recruited and the length of follow-up was 5.1 ± 1.3 years. At follow-up visit, subjects with PS at baseline had significantly lower FMD (-0.34% [-0.59 to -0.10]), greater cIMT (+0.01 mm [+0.001 to +0.013]), higher wake systolic blood pressure (SBP) (+2.6 mm Hg [+0.02 to +5.1]), sleep SBP (+3.0 mm Hg [+0.3 to +5.6]), sleep diastolic blood pressure (+2.2 mm Hg [+0.04 to +4.4]) and sleep mean arterial pressure (+2.2 mm Hg [+0.1 to +4.2]) compared to matched controls in the fully adjusted model for variables including change in OAHI and parental history of cardiovascular diseases. CONCLUSION Childhood PS is associated with poorer endothelial function, greater cIMT and higher ABP at 5-year follow-up irrespective of change in obstructive sleep apnoea severity.

Abstract
OBJECTIVES In obese adults the shape of the glucose response curve during an oral glucose tolerance test (OGTT) predicts future type 2 diabetes. Patients with an incessant increase or monophasic curves have increased risk compared to those with biphasic curves. Since type 2 diabetes is associated with increased cardiometabolic risk, we studied whether differences in OGTT response curve are associated with differences in cardiometabolic risk factors in healthy adolescents across a wide body mass index (BMI) range. METHODS Sixty-nine (33F/36M), white adolescents (age: 15.2 ± 1.7 years; BMI: 21.5 ± 4.7 kg/m2; mean ± SD) were studied. Risk factors measured included percent body fat, blood pressure, lipids, augmentation index, reactive hyperemia, endothelin 1, plasminogen activator 1, inflammatory markers (interleukin 6, c-reactive protein), insulin secretion, insulin sensitivity (Matusda index), and disposition index (DI). RESULTS Thirty-two subjects had biphasic responses; 35 subjects had monophasic responses and two females had incessant increases. Sex did not affect the frequency of responses. Glucose area under the curve during OGTT was greater in those with a mono vs. biphasic curves (p=0.01). Disposition index was markedly lower in subjects with a monophasic curve than in those with a biphasic curve (3.6 [2.3-5.0] vs. 5.8 [3.8-7.6], median [25th, 75th%] p=0.003). Triglyceride to high-density lipoprotein cholesterol (HDL) ratio was higher in subjects with a monophasic curve (p=0.046). CONCLUSIONS The decreased disposition index indicates that in healthy adolescents a monophasic response to OGTT is due to decreased insulin secretion relative to the degree of insulin resistance present. This was not associated with differences in most other cardiometabolic risk markers. TRIAL REGISTRATION Clinical Trials.gov, NCT02821104.

Abstract
Cardiovascular diseases are the main cause of mortality worldwide, and childhood excess weight/obesity are strong correlators of accumulated risk in later life. A relationship between maternal preeclampsia and offspring's childhood obesity is recognized, but most studies fail to control for strong confounders. Our goal is to analyze the association between preeclampsia and childhood excess weight/obesity, after accounting for important confounders. We recruited 5133 women with singleton pregnancies during admission for delivery. Sixty-seven pregnancies were complicated by preeclampsia. Maternal and children outcomes were assessed at 10 years of age. We analyzed the association between preeclampsia and childhood excess weight/obesity by fitting a linear regression model (using offspring body mass index (BMI) z-score at 10 years of age) and a logistic regression model (using excess weight/obesity status). We then controlled both models for known confounders, namely maternal prepregnancy BMI, parity, and smoking during pregnancy. At 10 years of age, offspring of preeclamptic mothers had a higher BMI z-score and were more likely classified as overweight/obese, but these differences were not statistically significant. After controlling for maternal prepregnancy BMI, parity, and smoking during pregnancy, there was a high magnitude change in the beta coefficient of preeclampsia in the linear (0.175; -0.014) and the logistic regression models (1.48; 1.23) suggesting that the association between preeclampsia and childhood excess weigh/obesity is significantly confounded by these variables. These confounders also showed a significant association with childhood obesity. This finding suggests that in utero exposure to preeclampsia seems to have less impact in childhood obesity than the previously described confounders.

Abstract
There is evidence that a number of medical conditions and co-morbidities are associated with obesity in young children. This review explored whether there is evidence of associations with other conditions or co-morbidities. Observational studies of young children (mean age < 10 years) were identified using electronic searches of five databases (MEDLINE, Embase, CINAHL, AMED and SPORTDiscus). Of 27 028 studies screened, 41 (comprising 44 comparisons) met the inclusion criteria. These studies provided data on five distinct diseases/conditions: asthma (n = 16), vitamin D deficiency (n = 10), iron deficiency (n = 10), allergies (n = 4) and flat-footedness (n = 4). Thirty-two studies were appropriate for meta-analysis using random-effects models, and revealed obesity was significantly associated with having asthma (OR 1.5, 95% CI 1.3-1.7), vitamin D deficiency (OR 1.9, 95% CI 1.4-2.5) and iron deficiency (OR 2.1, 95% CI 1.4-3.2). Heterogeneity (I2 ) ranged from 57% to 61%. Narrative synthesis was conducted for all studies. There was no evidence of a consistent association between obesity in young children and eczema, dermatitis or rhinitis due to the low number of studies. However, there was an association with flat-footedness. These results have implications for health policy and practice and families. Further research leading to a greater understanding of the associations identified in this review is suggested.

Abstract
Carotid intima-media thickness (cIMT) and carotid stiffness (CS) are important markers of atherosclerotic risk in the young. We assessed a novel third-generation method for its applicability in large population-based epidemiologic studies to determine strengths, limitations, completeness and predictors of unsuccessful measurement. Four thousand seven hundred ninety-eight 14- to 31-y-old participants of the German KiGGS cohort, which is based on a nationally representative sample with 11-y follow-up, underwent B-mode ultrasound examinations of the left and right common carotid artery with semi-automatic edge detection and automatic electrocardiogram-gated real-time quality control based on a sophisticated snake algorithm and subpixel interpolation. Overall completeness was 98% for far wall cIMT and 89% for CS parameters. Plane-specific completeness varied from 92%-96% for far wall and from 64%-69% for near-wall cIMT. Obesity independently predicted unsuccessful cIMT and CS measurements with odds ratios of 12.67 (95% confidence interval: 5.50-29.19) and 7.30 (4.87-10.94) compared with non-overweight after adjustment for blood pressure, cholesterol, smoking, hazardous drinking, age, sex and sonographer. Inter- and intra-rater reliabilities of cIMT and CS parameters in a sample of 15 young adults were good or excellent. Third-generation cIMT and CS measurements in the young with semi-automatic edge-detection and automatic real-time quality control has been successfully standardized with high reliability and very high completeness in a national survey setting. This provides a strong methodological foundation for further validation of the predictive value of cIMT and CS for atherosclerotic risk in the young.

Determinants of Intima-Media Thickness in the Young: The ALSPAC Study. JACC Cardiovasc Imaging 2021; 14:468-478.

Abstract
OBJECTIVES This study characterized the determinants of carotid intima-media thickness (cIMT) in a large (n > 4,000) longitudinal cohort of healthy young people age 9 to 21 years. BACKGROUND Greater cIMT is commonly used in the young as a marker of subclinical atherosclerosis, but its evolution at this age is still poorly understood. METHODS Associations between cardiovascular risk factors and cIMT were investigated in both longitudinal (ages 9 to 17 years) and cross-sectional (ages 17 and 21 years) analyses, with the latter also related to other measures of carotid structure and stress. Additional use of ultra-high frequency ultrasound in the radial artery at age 21 years allowed investigation of the distinct layers (i.e., intima or media) that may underlie observed differences. RESULTS Fat-free mass (FFM) and systolic blood pressure were the only modifiable risk factors positively associated with cIMT (e.g., mean difference in cIMT per 1-SD increase in FFM at age 17: 0.007 mm: 95% confidence interval [CI]: 0.004 to 0.010; p < 0.001), whereas fat mass was negatively associated with cIMT (difference: -0.0032; 95% CI: 0.004 to -0.001; p = 0.001). Similar results were obtained when investigating cumulative exposure to these factors throughout adolescence. An increase in cIMT maintained circumferential wall stress in the face of increased mean arterial pressure when increases in body mass were attributable to increased FFM, but not fat mass. Risk factor-associated differences in the radial artery occurred in the media alone, and there was little evidence of a relationship between intimal thickness and any risk factor. CONCLUSIONS Subtle changes in cIMT in the young may predominantly involve the media and represent physiological adaptations as opposed to subclinical atherosclerosis. Other vascular measures may be more appropriate for the identification of arterial disease before adulthood.

Abstract
Although relatively rare in childhood, primary hypertension (PH) is thought to have originated in childhood and may be even determined perinatally. PH prevalence increases in school-age children and affects 11% of 18-year-old adolescents. Associated with metabolic risk factors, elevated blood pressure in childhood is carried into adulthood. Analysis of the phenotype of hypertensive children has revealed that PH is a complex of anthropometric and neuro-immuno-metabolic abnormalities, typically found in hypertensive adults. Children with elevated blood pressure have shown signs of accelerated biological development, which are closely associated with further development of PH, metabolic syndrome, and cardiovascular disease in adulthood. At the time of diagnosis, hypertensive children were reported to have significant arterial remodelling expressed as significantly increased carotid intima-media thickness, increased stiffness of large arteries, lower area of microcirculation, and decreased endothelial function. These changes indicate that their biological age is 4 to 5 years older than their normotensive peers. All these abnormalities are typical features of early vascular aging described in adults with PH. However, as these early vascular changes in hypertensive children are closely associated with features of accelerated biological development and neuro-immuno-metabolic abnormalities observed in older subjects, it seems that PH in childhood is not only an early vascular aging event, but also an early biological maturation phenomenon.

Abstract
Background Bariatric surgery is an effective long-term weight loss strategy yielding improvements in neurocognitive function; however, the mechanism(s) responsible for these improvements remains unclear. Here, we assessed the feasibility of using magnetic resonance imaging (MRI) to evaluate whether cerebral vascular reactivity (CVR) is impaired in severely obese bariatric surgery candidates compared with normal weight healthy controls and whether CVR improves following bariatric surgery. We also investigated whether changes in CVR were associated with changes in cognitive function. Methods Bariatric surgery candidates (n = 6) were compared with normal weight healthy controls of a similar age (n = 10) at baseline, and then reassessed 2 weeks and 14 weeks following sleeve gastrectomy bariatric surgery. Young reference controls (n = 7) were also studied at baseline to establish the range of normal for each outcome measure. Microvascular and macrovascular CVR to hypercapnia (5% CO2) were assessed using blood-oxygen-level-dependent (BOLD) MRI, and changes in the middle cerebral artery (MCA) cross-sectional area, respectively. Cognitive function was assessed using a validated neurocognitive software. Results Compliance with the CVR protocol was high. Both macro- and micro-cerebrovascular function were highest in the young reference controls. Cognitive function was lower in obese bariatric surgery candidates compared with normal weight controls, and improved by 17% at 2 weeks and 21% by 14 weeks following bariatric surgery. To our surprise, whole-brain CVR BOLD did not differ between obese bariatric surgery candidates and normal weight controls of similar age (0.184 ± 0.101 vs. 0.192 ± 0.034 %BOLD/mmHgCO2), and did not change after bariatric surgery. In contrast, we observed vasoconstriction of the MCA during hypercapnia in 60% of the obese patients prior to surgery, which appeared to be abolished following bariatric surgery. Improvements in cognitive function were not associated with improvements in either CVR BOLD or MCA vasodilation after bariatric surgery. Conclusions Assessing CVR responses to a hypercapnic challenge with MRI was feasible in severely obese bariatric patients. However, no changes in whole-brain BOLD CVR were observed following bariatric surgery despite improvements in cognitive function. We recommend that future large trials assess CVR responses to cognitive tasks (rather than hypercapnia) to better define the mechanisms responsible for cognitive function improvements following bariatric surgery.

Abstract
C-type natriuretic peptide (CNP) is an endogenous adipogenesis regulator whose plasma levels in childhood are known, while no data are available on its expression. Our aim was to evaluate both CNP plasma levels and CNP system expression in whole blood obtained from normal-weight (N, n = 24) and obese (O, n = 16) adolescents (age:13.5 ± 0.4 years). Endothelial function was assessed measuring reactive hyperemia index (RHI). CNP plasma levels, evaluated with specific RIA, resulted significantly lower in O than in N (6.1 ± 0.8 vs.15.2 ± 1.3 pg/mL; p < 0.0001), while CNP/NPR-B/NPR-C mRNA, measured by Real-Time PCR, resulted similar in N (4.1 ± 1.7; 5.0 ± 1.6; 2.2 ± 0.9) and in O (4.3 ± 1.6; 3.5 ± 1.1; 2.3 ± 0.8). RHI was significantly lower in O than in N (1.4 ± 0.08 vs.2.1 ± 0.04, p < 0.0001). Dividing all subjects according to the RHI median value, irrespective of the presence or absence of obesity (Group 1 > 1.9, n = 23, Group 2 < 1.9, n = 17), CNP plasma concentrations resulted significantly (p = 0.014) higher in Group 1 (14.6 ± 1.6) than in Group 2 (7.5 ± 1.0), showing a significant correlation with RHI (p = 0.0026), while CNP mRNA expression was, surprisingly, higher in Group 2 (7.0 ± 2.3) than in Group 1 (1.8 ± 0.4; p = 0.02). NPR-B mRNA resulted similar in both Groups (4.3 ± 1.6; 4.7 ± 1.3) and NPR-C significantly higher in Group 2 (p = 0.02). Our data suggest different trends between CNP plasma levels and expression, assessed for the first time in whole blood, that could reflect changes occurring both at CNP transcriptional level in activated leukocytes due to inflammation, and at circulating levels, due to CNP paracrine/autocrine activities. This could represent an interesting area for new therapies able to modulate endothelial dysfunction.

Increased body fat and reduced insulin sensitivity are associated with impaired endothelial function and subendocardial viability in healthy, non-Hispanic white adolescents. Pediatr Diabetes 2019; 20:842-848. [PMID: 31329355 PMCID: PMC7207768 DOI: 10.1111/pedi.12896] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 07/11/2019] [Accepted: 07/15/2019] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Cardiovascular disease has its origins in adolescents. Endothelial dysfunction, arterial stiffness, and decreased endocardial oxygen supply: demand ratios are early functional markers of cardiovascular risk. The goal of this study was to determine the relationships of these markers to physical, inflammatory, and metabolic markers in healthy non-Hispanic, white adolescents. METHODS Thirty-four of the 75 subjects were female. Mean age was 15.0 ± 1.7 years and mean body mass index (BMI) was 22.0 ± 5.8 kg/m2 (mean ± SD). Reactive hyperemia was measured using venous occlusion plethysmography. Arterial tonometry was used to measure the augmentation index (AIx75 ) and the Buckberg subendocardial viability ratio. Blood samples were taken to measure inflammatory and lipid markers and oral glucose tolerance test was used to assess insulin sensitivity. RESULTS Reactive hyperemia decreased as body mass and fat mass increased. It also decreased with increasing neutrophil count. The Buckberg index was higher in males and was positively related to insulin sensitivity even when accounting for age, sex, and resting heart rate. AIx75 was not related to any of the other variables. CONCLUSIONS These results demonstrate that increased fat mass and decreased insulin sensitivity are related to poorer vascular function and cardiac risk in adolescents before the development of actual cardiovascular disease.

Urinary Biomarkers of Inflammation and Oxidative Stress Are Elevated in Obese Children and Correlate with a Marker of Endothelial Dysfunction. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:9604740. [PMID: 31737180 PMCID: PMC6817929 DOI: 10.1155/2019/9604740] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Revised: 08/10/2019] [Accepted: 08/16/2019] [Indexed: 01/01/2023]
Abstract
Obesity is a state of chronic low-level inflammation closely associated with oxidative stress. Childhood obesity is associated with endothelial dysfunction, inflammation, and oxidative stress markers individually. This study was aimed at determining the association between the biomarkers of inflammation, oxidative stress, and endothelial dysfunction in urine samples of healthy, overweight, and obese children. Eighty-eight elementary school children aged between 6 and 10 years participated in this study. Anthropometric measurements were measured using WHO recommendations. The biomarkers of low-grade inflammation such as C-reactive protein (CRP), interleukin-6 (IL-6), and α-1-acid glycoprotein (AGP); oxidative stress markers such as 8-isoprostane and 8-hydroxy-2'-deoxyguanosine (8-OHdG); and endothelin-1 (ET-1) were analyzed in urine samples. The area under the curve (AUC) by the receiver operating characteristics (ROC) was analyzed to identify the best urinary biomarker in childhood obesity. Linear regression and Pearson correlation were analyzed to determine the association between the parameters. The obese participants have significantly increased levels of CRP, AGP, IL-6, and 8-isoprostane compared to normal-weight participants. The overweight participants had significantly increased levels of ET-1 and 8-OHdG but not the obese group compared to the NW group. The AUC for urinary CRP (AUC: 0.847, 95% CI: 0.765-0.930; p < 0.0001) and 8-isoprostane (AUC: 0.857, 95% CI: 0.783-0.932; p < 0.0001) showed a greater area under ROC curves compared to other inflammatory and oxidative markers. The urinary CRP and 8-isoprostane significantly correlated with the obesity measures (body mass index, waist circumference, and waist-to- height ratio) and ET-1, inflammatory, and oxidative markers. The increased urinary inflammatory markers and 8-isoprostane can serve as a noninvasive benchmark for early detection of the risk of developing cardiovascular disease.

Abstract
Atherosclerosis underlies most myocardial infarctions and ischemic strokes. The timing of onset and the rate of progression of atherosclerosis differ between individuals and among arterial sites. Physical manifestations of atherosclerosis may begin in early life, particularly in the abdominal aorta. Measurement of the abdominal aortic intima-media thickness by external ultrasound is a non-invasive methodology for quantifying the extent and severity of early atherosclerosis in children, adolescents, and young adults. This review provides an evidence-based rationale for the assessment of abdominal aortic intima-media thickness-particularly as an age-appropriate methodology for studying the natural history of atherosclerosis in the young in comparison to other methodologies-establishes best practice methods for assessing abdominal aortic intima-media thickness, and identifies key gaps in the literature, including those that will identify the clinical relevance of this measure.

Abstract
BACKGROUND Intermittent energy restriction (IER) is an effective obesity management strategy in adults. OBJECTIVE The aim of this study was to investigate the feasibility, effectiveness, and acceptability of IER in adolescents (aged 12-17 y) with obesity [adult equivalent body mass index (BMI; kg/m2) ≥30]. METHODS During weeks 1-12 participants followed an IER dietary plan consisting of a very-low-energy diet (VLED) 3 d/wk (500-600 kcal/d) and an eating plan consistent with national dietary guidelines 4 d/wk. For weeks 13-26 participants chose to continue with 1-3 VLED d/wk or follow a prescriptive eating plan. Primary outcomes were feasibility and change in BMI expressed as a percentage of the 95th percentile (BMI %95th percentile) at 12 wk. Secondary outcomes were diet acceptability, body composition, cardiometabolic risk, vascular structure and function, quality of life (Pediatric Quality of Life Inventory), and eating behaviors [Dutch Eating Behavior Questionnaire (DEBQ-C)]. Linear mixed models were used to assess change in outcome measures. RESULTS Of 45 adolescents invited to participate, 30 adolescents (mean ± SD age: 14.5 ± 1.4 y, female n = 25) with a median BMI of 34.9 (range: 27.7-52.4) were recruited. At 12 wk, 23 participants chose to continue with the VLED 2-3 d/wk, and 21 completed the study, indicating the feasibility of IER. Consistent with intention-to-treat analysis, BMI %95th percentile was reduced at 12 wk (difference in estimated marginal means ± SEMs: -5.6 ± 1.1, P < 0.001) and 26 wk (-5.1 ± 1.9, P = 0.013) compared with baseline. Plasma triglycerides were reduced at 26 wk from baseline (-0.33 ± 0.12 mmol/L, P = 0.03). Body fat percentage reduced between 12 and 26 wk (-1.57% ± 0.76%, P = 0.05). Carotid intima-media thickness (CIMT) (-0.06 ± 0.01 mm, P < 0.001) and flow-mediated dilation (absolute increase 0.44% ± 0.11%, P = 0.001) improved between baseline and 12 wk, with reduced CIMT maintained at 26 wk (P < 0.001). DEBQ-C and Pediatric Quality of Life Inventory scores improved throughout the intervention. Nineteen adolescents completed an acceptability interview, rating IER as easy and pleasant to follow (mean ± SD: +2.1 ± 1.2; +1.9 ± 1.2, respectively) on a Likert scale from -4 to +4. CONCLUSION IER is a feasible, effective, and acceptable intervention in adolescents with obesity achieving reductions in BMI and cardiovascular disease risk.

Abstract
OBJECTIVE To evaluate daily eating frequency (main meals and snacks) in relation to weight status in children aged 3-9 years, representative of the Portuguese population. DESIGN Cross-sectional study. Dietary intake was estimated as the mean of two non-consecutive days of food diaries, followed by face-to-face interviews. Weight and height were measured by trained observers. Eating occasions (EO) were defined by the children's caregiver; an EO was considered separate if the time of consumption was different from other EO and it provided at least 209 kJ (50 kcal). Main meals defined as 'breakfast', 'lunch' and 'dinner' could be selected only once per day. The remaining EO were considered snacks. The association between eating frequency and overweight/obesity was evaluated through logistic regressions weighted for the population distribution. SETTING National Food, Nutrition and Physical Activity Survey of the Portuguese population, 2015-2016. PARTICIPANTS Portuguese children aged 3-9 years with complete dietary data and anthropometric measurements (n 517). RESULTS Overall, the number of daily EO ranged from 3·5 to 11, and on average children had 5·7 daily EO. After adjustment for child's sex, age and total energy intake, and considering only plausible energy intake reporters, having < 3 snacks/d was positively associated with being overweight/obese (OR = 1·98; 95 % CI 1·00, 3·90), compared with having ≥ 3 snacks/d. CONCLUSIONS Lower daily frequency of EO was associated with increased odds of being overweight or obese in children. A higher eating frequency, maintaining the same energy intake, seems to contribute to a healthy body weight in children.

Abstract
BACKGROUND Tetralogy of Fallot (TOF) is one of the most common cyanotic congenital heart diseases (CHD) in children. Various surgical procedures including palliative shunts and TOF total correction (TFTC) were done with some complications, of which, the most common is pulmonary valve regurgitation (PR). Tadalafil is a phosphodiesterase 5 inhibitor which reduces pulmonary vascular resistance, and improves right ventricular function and vascular endothelium, and may have some beneficial effects after TFTC. METHODS We studied 18 patients with TOF and PR, with some impaired right ventricular function after TFTC. Tadalafil tablets at a dose of 1 mg per kg (maximum 40 mg) per day as a single dose was administered orally for 8 weeks. In all patients, before and after taking tadalafil, functional class assessment, electrocardiography (ECG) changes, some echocardiographic and endothelial function parameters [flow-mediated dilation (FMD) and intima-media thickness (IMT) of carotid artery], and exercise test were determined. RESULTS The patient's mean age was 10.11 ± 4.03 years, and the mean age of operation was 2.52 ± 1.12 years. The effect of tadalafil on different echocardiographic parameters and also on tricuspid valve regurgitation (TR) and PR severity and gradient was not significant. Moreover, it had no effects on QRS duration. Tadalafil had a significant effect on improving FMD and exercise test (P = 0.01). The effect of tadalafil on echocardiographic parameters, carotid artery IMT, and ECG parameters was not significant (P > 0.05). Tadalafil was tolerated well, and the most common side effects were headache and myalgia. CONCLUSION This study showed that tadalafil is a safe and well-tolerated drug. It might improve exercise performance, endothelial function, and functional class, and possibly could allow patients a longer period of well-being and could possibly delay the need for pulmonary valve replacement (PVR).

Abstract
Cardiovascular disease (CVD), as a possible consequence of endothelial dysfunction, is prevalent among HIV-infected patients despite successful administration of antiretroviral drugs. This warrants the routine clinical assessment of endothelial function in HIV-positive patients to circumvent potential CVD events. Several different non-invasive strategies have been employed to assess endothelial function in clinical research studies yielding inconsistencies among these reports. This review summarises the different techniques used for assessing endothelial function, with a focus on proposed blood-based biomarkers, such as endothelial leukocyte adhesion molecule-1 (E-selectin), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), von Willebrand factor (vWF), TNF-α, interleukin 6 (IL6) and soluble thrombomodulin (sTM). The identification of suitable blood-based biomarkers, especially those that can be measured using a point-of-care device, would be more applicable in under-resourced countries where the prevalence of HIV is high.

Abstract
Background Body mass index (BMI) has been suggested to be causally related to cardiovascular health in mid-to-late life, but this has not been explored systematically at younger ages - nor with detailed cardiovascular phenotyping. Recall-by-Genotype (RbG) is an approach that enables the collection of precise phenotypic measures in smaller studies, whilst maintaining statistical power and ability for causal inference. Methods In this study, we used a combination of conventional multivariable regression analysis, Mendelian randomization (MR) and sub-sample RbG methodologies to estimate the causal effect of BMI on gross-level and detailed cardiovascular health in healthy participants from the Avon Longitudinal Study of Parents and Children at age 17 (N=1420-3108 for different outcomes) and an independent sample from the same cohort (for RbG) study at age 21 (N=386-418). Results In both MR and RbG analyses, results suggested that higher BMI causes higher blood pressure (BP) and left ventricular mass index (LVMI) in young adults (e.g., difference in LVMI per kg/m2 using MR: 1.07g/m2.7; 95% CI: 0.62, 1.52; P=3.87x10-06 and per 3.58kg/m2 using RbG: 1.65g/m2.7 95% CI: 0.83, 2.47; P=0.0001). Additionally, RbG results suggested a causal role of higher BMI on higher stroke volume (SV: difference per 3.58kg/m2: 1.49ml/m2.04; 95% CI: 0.62, 2.35; P=0.001) and cardiac output (CO: difference per 3.58kg/m2: 0.11l/min/m1.83; 95% CI: 0.03, 0.19; P=0.01) but no strong evidence for a causal role on systemic vascular resistance or total arterial compliance. Neither analysis supported a causal role of higher BMI on heart rate. Conclusions Complementary MR and RbG causal methodologies, together with a range of sensitivity analyses, suggest that higher BMI is likely to cause worse cardiovascular health, specifically higher BP and LVMI, even in youth. Higher BMI also resulted in increased CO in the RbG study, which appeared to be solely driven by SV, as neither MR nor RbG analyses suggested a causal effect of BMI on heart rate. These consistent results support efforts to reduce BMI from a young age to prevent later adverse cardiovascular health and illustrate the potential for phenotypic resolution with maintained analytical power using RbG.

Abstract
Primary hypertension is not just an adult disorder. Current US population data on children and adolescents demonstrate a prevalence of elevated blood pressure (BP) and hypertension combined of over 10%. Recent reports from prospective cohort studies describe an association of high BP in childhood with hypertension in young adulthood. Excess adiposity is strongly associated with higher BP in childhood and increases risk for hypertension in adulthood. In addition to overweight/obesity, other exposures that raise the risk for high BP include low birthweight, dietary sodium, and stress. Using intermediate markers of cardiovascular injury, studies on hypertensive children report findings of cardiac hypertrophy, vascular stiffness, and early atherosclerotic changes. Impaired cognitive function has also been demonstrated in hypertensive children. Recent advances in clinical and translational research support the concept that the evolution of primary hypertension begins in childhood.

Abstract
INTRODUCTION Carotid intima-media thickness (CIMT) is a surrogate marker of atherosclerosis that is measured in adults and children to better understand the natural history of cardiovascular disease (CVD). In adults, CIMT is predictive of myocardial infarction and stroke. In children and adolescents, CIMT is used to assess vascular changes in the presence of CVD risk factors (obesity, hypertension, smoking, etc) or clinical conditions associated with a high risk for premature CVD. However, there is no comprehensive overview, in a life-course epidemiology perspective, of the risk factors and determinants of CIMT in children. It is also important to evaluate between-study differences in CIMT measurement methods and take them into consideration when drawing conclusions. Our objective is to systematically review the evidence on the relationship between CIMT and prenatal and postnatal exposures or interventions in children, as well as documenting and discussing the CIMT measurement methods. METHODS AND ANALYSIS Systematic searches of the Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica (EMBASE)and Central Register of Controlled Trials (CENTRAL) databases will be conducted. The reference lists and other literatures sources will be browsed. Observational and experimental studies in children from birth up to 18 years will be included. Prenatal and postnatal exposures or interventions assessed in relationship with CIMT will be considered for inclusion. Examples might include gestational age, obesity, hypertension, tobacco exposure, specific at-risk conditions (chronic kidney disease, diabetes, etc) or statin treatment. The outcome will be CIMT assessed by ultrasonography. The setting, scanning and measurement methods for each included study will be described in detail. Results will be synthesised descriptively and, if appropriate, will be pooled across studies to perform meta-analyses. Separate meta-analyses for each exposure or intervention type will be conducted. ETHICS AND DISSEMINATION This systematic review will be published in a peer-reviewed journal. A report will be prepared for clinicians and other healthcare decision-makers. PROSPERO REGISTRATION NUMBER CRD42017075169.

Abstract
OBJECTIVE Atherosclerosis developed during premenopausal years predicts postmenopausal atherosclerosis burden. Selective serotonin reuptake inhibitor (SSRI) antidepressants, recently approved for hot flushes, have been associated with increased ischemic stroke risk in several observational studies; however, effects on carotid artery atherosclerosis, a strong predictor of future vascular events, are unknown. METHODS The effects of chronic administration of a commonly prescribed SSRI, sertraline HCl, on atherosclerosis in the carotid artery was assessed in a placebo-controlled, longitudinal, randomized study of premeonopausal depressed and nondepressed cynomolgus monkeys (Macaca fascicularis; n = 42). Physiologic and behavioral phenotypes were evaluated at baseline and after 18 months of oral sertraline (20 mg/kg, n = 21) or placebo (n = 21). Carotid artery atherosclerosis was measured post mortem via histomorphometry. RESULTS Atherosclerosis extent in the right common carotid artery, on average, was 60% greater in sertraline-treated depressed monkeys compared with all other groups (P = 0.028). The results of linear regression analyses suggested that sertraline and depression effects on atherosclerosis were not mediated by their effects on behavioral and physiological risk factors. CONCLUSIONS These findings suggest that chronic SSRI treatment is associated with the progression of carotid artery atherosclerosis, which may increase the risk for future vascular events, particularly in depressed women. The underlying mechanism remains to be determined, but does not appear to be related to SSRI effects on traditional cardiovascular risk factors.

Abstract
Objective: To evaluate whether the obesity alters ultrasonographical markers of
metabolic and cardiovascular disease risk in children. Methods: A cross-sectional study evaluated 80 children aged between 6 and 10 years,
comparing 40 obese with 40 normal children. The following parameters were
assessed: weight; height; body mass index; arterial blood pressure; body
fat; basal metabolic rate; HDL-cholesterol, LDL-cholesterol and total
cholesterol; fasting insulin and glucose; quantitative insulin sensitivity
check index (QUICKI); homeostasis model of assessment - insulin resistance
(HOMA-IR); basal diameter of the brachial artery; brachial artery flow
mediated dilation (FMD) and of pulsatility index change (PI-C). Results: Significant differences were observed between obese vs. non-obese children:
systolic blood pressure (97.7±8.4 vs. 89.0±5.8 mmHg; p<0.01), diastolic
blood pressure (64.3±7.9 vs. 52.9±5.1 mmHg; p<0.01), proportion of body
fat (45.1±5.9 vs. 21.3±6.0%; p<0.01), basal metabolic rate (1216.1±102.1
vs. 1072.9±66.4 Kcal; p<0.01), total cholesterol (164.7±25.2 vs.
153.4±15.8 mg/dL; p=0.03), fasting insulin (7.1±5.2 vs. 2.8±1.8 pIU/mL;
p<0.01), HOMA-IR (1.5±1.1 vs. 0.6±0.4; p<0.01), basal diameter of the
brachial artery (2.5±0.3 vs. 2.1±0.3 mm; p<0.01); PI-C (-15.5±27.2 vs.
-31.9±15.5%; p<0.01), decreased QUICKI (0.4±0.05 vs. 0.4±0.03;
p<0.01), and FMD (6.6±3.2 vs. 15.6±7.3%; p<0.01). Conclusions: Obesity worsens ultrasonographical and laboratorial markers of metabolic and
cardiovascular disease risk in children.

Abstract
Atherosclerotic cardiovascular disease is a leading cause of death and disability worldwide, and the atherosclerotic process begins in childhood. Prevention or containment of risk factors that accelerate atherosclerosis can delay the development of atherosclerotic cardiovascular disease. Although current recommendations are to periodically screen for commonly prevailing risk factors for atherosclerosis in children, a single test that could quantify the cumulative effect of all risk factors on the vasculature, thus assessing arterial health, would be helpful in further stratifying risk. Measurement of pulse wave velocity and assessment of augmentation index - measures of arterial stiffness - are easy-to-use, non-invasive methods of examining arterial health. Various studies have assessed pulse wave velocity and augmentation index in children with commonly occurring conditions including obesity, hypertension, insulin resistance, diabetes mellitus, dyslipidaemia, physical inactivity, chronic kidney disease, CHD and acquired heart diseases, and in children who were born premature or small for gestational age. This article summarises pulse wave velocity and augmentation index assessments and the effects of commonly prevailing chronic conditions on arterial health in children. In addition, currently available reference values for pulse wave velocity and augmentation index in healthy children are included. Further research to establish widely applicable normative values and the effect of lifestyle and pharmacological interventions on arterial health in children is needed.

Abstract
BACKGROUND/PURPOSE To investigate the correlations among endothelial function assessment parameters, asymmetric dimethylarginine (ADMA)-related biomarkers, and traditional risk factors in adipose children. METHODS We enrolled adipose children aged 7-18 years between July 2014 and August 2016 as well as normal-weight controls from the outpatient clinic. Vascular measurements including echocardiography, carotid intima media thickness, pulse wave velocity (PWV), and flow-mediated dilation (FMD) were measured. Venous blood samples including traditional metabolic and endothelial dysfunction parameters were analyzed. Participants were grouped as adipose vs. normal-weight and as adipose with hypertension vs. adipose without hypertension. Clinical presentations, laboratory data, and cardiovascular measurement were compared. RESULTS Of the 105 enrolled children, 85 were adipose. Adipose children had higher systolic blood pressure, larger left ventricular (LV) mass, and adverse traditional metabolic biomarkers. FMD was significantly reduced (8.25 (5.32-12.06) % vs. 12.49 (7.18-16.58) %, p = 0.018) in the adipose group. PWV was markedly increased (4.65 (4.2-5.5) m/sec vs. 3.95 (3.38-4.35) m/sec, p < 0.001) in the hypertensive adipose children. Endothelial dysfunction parameters were not significantly changed in this study. CONCLUSION Adipose children were at higher risk of hypertension and LV hypertrophy. FMD, PWV and traditional cardiovascular biomarkers can detect subtle vascular changes. Hypertension is an important sign of arterial involvement in adipose children. Although ADMA-related biomarkers were not statistically significant, future studies are needed to confirm its correlation with adiposity and hypertension in children. The early detection and prevention of endothelial dysfunction may decrease the rate of progression to cardiovascular consequences in later life.

Abstract
BACKGROUND High-intensity intermittent training (HIIT) may serve as an effective alternative to traditional endurance training, since HIIT has been shown to induce greater improvements in aerobic fitness and health-related markers in adult populations. Our objective was to determine whether HIIT and supramaximal high-intensity intermittent training (supra-HIIT) would improve vascular structure and function in obese preadolescent boys. METHODS Before the baseline testing, 48 obese preadolescent boys, aged 8-12 years, were randomly assigned into control (CON; n = 16), HIIT (8 × 2 minutes at 90% peak power output, n = 16), and supra-HIIT (8 × 20 seconds at 170% peak power output, n = 16) groups. Both exercise groups performed exercises on a cycle ergometer three times/week for 12 weeks. RESULTS After 12 weeks, both HIIT and supra-HIIT did not affect body mass, body fat percentage, and waist circumference. Peak oxygen consumption (VO2peak) increased in both HIIT and supra-HIIT groups (p < 0.05). Both HIIT and supra-HIIT groups had higher resting metabolic rate than the control group (p < 0.05). A measure of arterial stiffness, brachial-ankle pulse wave velocity, and carotid intima-media thickness decreased after 12 weeks of HIIT and supra-HIIT program (all p < 0.05). Flow-mediated dilation, a measure of endothelium-dependent vasodilation, increased in both HIIT and supra-HIIT groups (all p < 0.05). CONCLUSIONS It is concluded that both HIIT and supra-HIIT have favorable effects on aerobic capacity, metabolic rate, vascular function and structure, and blood lipid profile in obese preadolescent boys. HIIT may be a time efficient and effective exercise for preventing future cardiovascular disease in obese children.

Abstract
OBJECTIVE In studies on the relationship between amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) concentration and height velocity in children, CNP has been implicated as an emerging new growth marker during childhood. It has been reported that besides its well-studied role in growth, plasma CNP levels are reduced in overweight and/or obese adolescents, suggesting CNP as a potential biomarker in childhood obesity. The primary goal of this study was to test this hypothesis in a Turkish population. METHODS Consent was taken from 317 children [ages 0-18 (158 girls, 159 boys)] and their parents. All subjects were physically examined; anthropometric measurements were obtained. Body mass index was calculated. During routine blood work, 1 mL extra blood was taken. Plasma NT-proCNP concentration was measured by enzyme-linked immunosorbent assay. RESULTS Results confirmed the previously described relationship between plasma NT-proCNP concentration and growth velocity. Plasma NT-proCNP concentration showed a negative correlation with age, weight, and height in children. Gender was not a factor that alters the age-dependent plasma NT-proCNP concentration until puberty. CONCLUSION Unlike previous reports, plasma NT-proCNP concentration of overweight/obese children was not significantly lower than that of children with normal weight in age groups analyzed in a Turkish population. Thus, it is too early to conclude that CNP is a potential biomarker in childhood obesity. Further studies are necessary to address this question.

Abstract
Increasing prevalence of hypertension (HTN) in children and adolescents has become a significant public health issue driving a considerable amount of research. Aspects discussed in this document include advances in the definition of HTN in 16 year or older, clinical significance of isolated systolic HTN in youth, the importance of out of office and central blood pressure measurement, new risk factors for HTN, methods to assess vascular phenotypes, clustering of cardiovascular risk factors and treatment strategies among others. The recommendations of the present document synthesize a considerable amount of scientific data and clinical experience and represent the best clinical wisdom upon which physicians, nurses and families should base their decisions. In addition, as they call attention to the burden of HTN in children and adolescents, and its contribution to the current epidemic of cardiovascular disease, these guidelines should encourage public policy makers to develop a global effort to improve identification and treatment of high blood pressure among children and adolescents.

Abstract
BACKGROUND With increasing rates of hypertension, obesity, and diabetes in the pediatric population, wide available, and reproducible methods are necessary to evaluate arterial structure and function in children and adolescents. METHODS MEDLINE/Pubmed was searched for articles published in years 2012-2017 on methodology of, current knowledge on, and limitations of the most commonly used methods to evaluate central, proximal and coronary arteries, as well as endothelial function in pediatric patients. RESULTS Among 1528 records screened (including 1475 records from years 2012 to 2017) 139 papers were found suitable for the review. Following methods were discussed in this review article: ultrasound measurements of the intima-media thickness, coronary calcium scoring using computed tomography, arterial stiffness measurements (pulse wave velocity and pulse wave analysis, carotid artery distensibility, pulse pressure, and ambulatory arterial stiffness index), ankle-brachial index, and methods to evaluate vascular endothelial function (flow-mediated vasodilation, peripheral arterial tonometry, Doppler laser flowmetry, and cellular and soluble markers of endothelial dysfunction). CONCLUSIONS Ultrasonographic measurement of carotid intima-media thickness and measurement of pulse wave velocity (by oscillometry or applanation tonometry) are highly reproducible methods applicable for both research and clinical practice with proved applicability for children aged ≥6 years or with height ≥120cm. Evaluation of ambulatory arterial stiffness index by ambulatory blood pressure monitoring is another promising option in pediatric high-risk patients. Clearly, further studies are necessary to evaluate usefulness of these and other methods for the detection of subclinical arterial damage in children.

Abstract
BACKGROUND/OBJECTIVES Endothelial dysfunction predicts mortality but it is unknown whether childhood obesity predicts adult endothelial dysfunction. The aim of this study was to determine whether anthropometric indices of body fat in childhood, adolescence and early midlife are associated with endothelial dysfunction in early midlife. SUBJECTS/METHODS Participants belonged to a representative birth cohort of 1037 individuals born in Dunedin, New Zealand in 1972 and 1973 and followed to age 38 years, with 95% retention (the Dunedin Multidisciplinary Health and Development Study). We assessed anthropometric indices of obesity at ages 3, 5, 7, 9, 11, 13, 15, 18, 21, 26, 32 and 38 years. We tested associations between endothelial function assessed by peripheral arterial tonometry (PAT) at age 38 and; age 38 cardiovascular risk factors; age 3 body mass index (BMI); and four BMI trajectory groups from childhood to early midlife. RESULTS Early midlife endothelial dysfunction was associated with BMI, large waist circumference, low high-density lipoprotein cholesterol, low cardiorespiratory fitness and increased high-sensitivity C-reactive protein. After adjustment for sex and childhood socioeconomic status, 3-year-olds with BMI 1 s.d. above the mean had Framingham-reactive hyperemia index (F-RHI) ratios that were 0.10 below those with normal BMI (β=-0.10, 95% confidence interval (CI) -0.17 to -0.03, P=0.007) at age 38. Cohort members in the 'overweight', 'obese' and 'morbidly obese' trajectories had F-RHI ratios that were 0.08 (β=-0.08, 95% CI -0.14 to -0.03, P=0.003), 0.13 (β=-0.13, 95% CI -0.21 to -0.06, P<0.001) and 0.17 (β=-0.17, 95% CI -0.33 to -0.01, P=0.033), respectively, below age-peers in the 'normal' trajectory. CONCLUSIONS Childhood BMI and the trajectories of BMI from childhood to early midlife predict endothelial dysfunction evaluated by PAT in early midlife.

Abstract
CONTEXT As opposed to coronary heart disease (CHD) mortality, cardiovascular mortality attributed to non-CHD causes has increased. OBJECTIVE To evaluate the association of body mass index (BMI) in late adolescence with mortality attributed to non-CHD cardiovascular sequelae. DESIGN AND SETTING A nationwide cohort. PARTICIPANTS A total of 2,294,139 adolescents examined between 1967 and 2010. INTERVENTIONS Height and weight were measured at age 17. All cardiovascular disease-specific outcomes, coded by the Central Bureau of Statistics from death notifications as the underlying cause of death, were obtained by linkage. Cox hazards models were applied. MAIN OUTCOME MEASUREMENTS Death attributed to fatal arrhythmias, hypertensive heart disease, cardiomyopathies, arterial disease, heart failure, and pulmonary embolism. RESULTS During 42,297,007 person-years of follow-up, there were 3178 deaths due to cardiovascular causes, of which 279, 122, 121, 114, 94, and 70 were attributed to the main outcomes, respectively. BMI was positively associated with all study outcomes with hazard ratios (HRs) per unit increment in BMI ranging from 1.09 [95% confidence interval (CI): 1.03 to 1.16] for arterial disease to 1.16 (95% CI: 1.11 to 1.21) for hypertensive heart disease. When BMI was treated as a categorical variable, a graded increase in risk was evident from the high-normal (22.0 to <25.0 kg/m2) to the overweight to the obese categories, with HRs of 1.4, 1.7, and 3.7 for arrhythmias; 1.9, 4.1, and 8.0 for hypertensive heart disease; 1.5, 2.4, and 4.0 for cardiomyopathies, 2.7, 5.0, and 3.5; for arterial disease, 1.7, 2.7, and 5.4 for heart failure; and 1.3, 1.8, and 3.0 for pulmonary embolism. Findings persisted in extensive sensitivity analyses. CONCLUSIONS Adolescent BMI within the accepted normal range is associated with non-CHD nonstroke cardiovascular outcomes.

Man E, Cheung PT, Cheung YF. Associations between arterial structure and function and serum levels of liver enzymes in obese adolescents. J Paediatr Child Health 2017; 53:691-697. [PMID: 28383828 DOI: 10.1111/jpc.13528] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Revised: 11/04/2016] [Accepted: 12/11/2016] [Indexed: 11/27/2022]
Abstract
AIM To determine the structural and functional alterations of systemic arteries in obese adolescents and their relationships with adiposity, metabolic and lipid profile, and serum liver enzyme levels. METHODS Carotid intima-media thickness (IMT), carotid stiffness index, and brachial-ankle pulse wave velocity (baPWV) were measured in 56 obese adolescents and 58 lean controls. Obese adolescents had additional liver ultrasound and determination of fasting blood indices of glucose metabolism and lipid profile, and serum levels of liver enzymes. RESULTS Carotid IMT (P < 0.0001), carotid stiffness index (P < 0.0001) and baPWV (P = 0.001) were significantly greater in obese than control subjects. Thirty-seven (66%) obese subjects had fatty liver changes and their aspartate aminotransferase, alanine aminotransferase (ALT), alkaline phosphatase, and gamma-glutamyl transferase levels were significantly higher than those without (all P < 0.05). Univariate analyses showed positive correlations between serum ALT (r = 0.29, P = 0.03) and alkaline phosphatase (r = 0.28, P = 0.04) levels and carotid IMT, aspartate aminotransferase level and carotid stiffness (r = 0.41, P = 0.002), and gamma-glutamyl transferase level and baPWV (r = 0.34, P = 0.02) in obese subjects. Multivariate linear regression revealed serum ALT level (β = 0.02, P = 0.006) as an independent correlate of carotid stiffness. CONCLUSION Obese adolescents have increased carotid IMT and stiffness, which are associated positively with serum liver enzyme levels.
