RESUMEN
The objectives of this study were to develop age- and sex-specific reference percentiles for fat mass index (FMI) and fat-free mass index (FFMI) in adolescents aged 14 to 19 years and to determine differences in overweight/obesity classification by FMI and body mass index (BMI). The EVA4YOU study is a single-center cross-sectional study conducted in western Austria. Cardiovascular risks including anthropometric measurements and bioelectrical impedance analysis were assessed in adolescents (mean age 17 years). FMI and FFMI were calculated as the ratio of fat mass (FM) and fat-free mass (FFM) to the square of height and compared to study population-specific BMI percentiles. One thousand four hundred twenty-two adolescents were included in the analysis. Girls had a significantly higher mean FM and FMI and a significantly lower mean FFM, FFMI (p < 0.001, each), and mean BMI (p = 0.020) than boys. Body composition classification by FMI and BMI percentiles shows a concordance for the < 75th and > 97th percentile, but a significant difference in percentile rank classifications between these two cut-off values (all p < 0.05). Based on FMI, 15.5% (221/1422) of the whole population and 29.4% (92/313) of those between the 75th and 97th percentiles are classified one category higher or lower than those assigned by BMI. CONCLUSION: Classification of normal or pathologic body composition based on BMI and FMI shows good accordance in the clearly normal or pathologic range. In an intermediate range, FMI reclassifies categories based on BMI in more than a quarter of adolescents. Cut-off values to differentiate normal from pathologic FMI values on a biological basis are needed. TRIAL REGISTRATION: The study is registered at www. CLINICALTRIALS: gov (Identifier: NCT04598685; Date of registration: October 22, 2020). WHAT IS KNOWN: ⢠Chronic non-communicable diseases (NCDs) are the leading cause of morbidity and mortality globally, with major risk factors including unhealthy diets, harmful behaviors, and obesity. Obesity in children and adolescents is a key risk factor for later NCDs, which is commonly measured by Body Mass Index (BMI). ⢠BMI can be misleading as it doesn't distinguish between fat mass (FM) and fat-free mass (FFM), leading to potential misclassification of obesity in children. Previous studies have already suggested the use of the Fat Mass Index (FMI) and Fat-Free Mass Index (FFMI) as a more accurate measures of body composition. WHAT IS NEW: ⢠This study adds the first age- and sex-specific reference values for FMI and FFMI in Austrian adolescents using bioelectrical impedance analysis (BIA) as a safe and secure measurement method of a large representative cohort. ⢠We found percentile misclassification between BMI and FMI when categorizing for obesity, especially in intermediate categories of body composition. Furthermore, when comparing the new reference values for FMI and FFMI to existing ones from the US, UK, and Germany we could show a good alignment within the European cohorts and major differences with American values, indicating and confirming the difference of FMI and FFMI for different populations of different ethnical background, living on different continents.

The number of adults with congenital heart defects (CHD) is steadily rising and amounts to approximately 360,000 in Germany. CHD is often associated with pulmonary hypertension (PH), which may develop early in untreated CHD. Despite timely treatment of CHD, PH not infrequently persists or recurs in older age and is associated with significant morbidity and mortality.The revised European Society of Cardiology/European Respiratory Society 2022 guidelines for the diagnosis and treatment of PH represent a significant contribution to the optimized care of those affected. However, the topic of "adults with congenital heart disease" is addressed only relatively superficial in these guidelines. Therefore, in the present article, this topic is commented in detail from the perspective of congenital cardiology.
RESUMEN
BACKGROUND AND AIMS: Preterm birth has been linked with an increased risk of cardiovascular (CV) disease from childhood into adolescence and early adulthood. In this study, we aimed to investigate differences in CV health profiles between former term- and preterm-born infants in a cohort of Tyrolean adolescents. METHODS: The Early Vascular Aging (EVA)-Tyrol study is a population-based non-randomized controlled trial, which prospectively enrolled 14- to 19-year-old adolescents in North Tyrol, Austria and South Tyrol, Italy between 2015 and 2018. Metrics of CV health (body mass index (BMI), systolic (SBP) and diastolic blood pressure (DBP), smoking, physical activity, dietary patterns, total cholesterol and fasting blood glucose) were assessed and compared between former term- and preterm-born girls and boys. RESULTS: In total, 1,491 study participants (59.5% female, mean age 16.5 years) were included in the present analysis. SBP and DBP were significantly higher in former preterm-born adolescents (mean gestational age 34.6 ± 2.4 weeks) compared to term-born controls (p < 0.01). In the multivariate regression analysis these findings remained significant after adjustment for potential confounders in all models. No differences were found in all other CV health metrics. The number of participants meeting criteria for all seven health metrics to be in an ideal range was generally very low with 1.5% in former term born vs. 0.9% in former preterm born adolescents (p = 0.583). CONCLUSIONS: Preterm birth is associated with elevated SBP and DBP in adolescence, which was even confirmed for former late preterm-born adolescents in our cohort. Our findings underscore the importance of promoting healthy lifestyles in former term- as well as preterm-born adolescents. In addition, we advise early screening for hypertension and long-term follow-up in the group of preterm-born individuals.

BACKGROUND: Migraine with aura is associated with an increased risk of cardiovascular disease, yet the pathophysiology is unknown. Suggested underlying mechanisms of aura formation point into the direction of an abnormal vasoreactivity that also extends to the extracranial vasculature. METHODS: In the Early Vascular Ageing Tyrol study, a community-based non-randomized controlled trial conducted in 45 schools and companies in Tyrol (Austria) and South-Tyrol (Italy) between May 2015 and September 2018 aiming to increase cardiovascular health in adolescents, headache syndromes were classified according to the International Classification of Headache Disorders in a face-to-face interview. Carotid-femoral pulse-wave-velocity was measured by applanation tonometry and carotid intima-media-thickness by high-resolution ultrasound of the distal common carotid arteries. Differences in pulse-wave-velocity and carotid intima-media-thickness in youngsters with migraine with aura were compared respectively to those without headache and with other headaches by multivariable linear regression analysis. RESULTS: Of the 2102 study participants 1589 were aged 14 to 19 (mean 16.8) years and had complete data. 43 (2.7%) reported migraine with aura and 737 (46.4%) other headaches. Mean pulse-wave-velocity was 6.17 m/s (± 0.85) for migraine with aura, 6.06 m/s (± 0.82) for all other headaches and 6.15 (0.95) m/s for participants without headaches. Carotid intima-media-thickness was 411.3 µm (± 43.5) for migraine with aura, 410.9 µm (± 46.0) for all other headaches and 421.6 µm (± 48.4) for participants without headaches. In multivariable linear regression analysis, we found no differences in carotid-femoral pulse-wave-velocity or carotid intima-media-thickness in young subjects with migraine with aura, all other headaches, or no headaches. CONCLUSIONS: In line with previous large-scale studies in adults, we could not demonstrate relevant associations of migraine with aura with markers of arterial stiffness or subclinical atherosclerosis making early vascular ageing an unlikely pathophysiological link between migraine with aura and cardiovascular diseases. TRIAL REGISTRATION: First registered on ClinicalTrials.gov 29/04/2019 (NCT03929692).

Pulmonary hypertension (PH) in childhood differs from that of adulthood particularly in the specific pathophysiology of congenital heart disease-associated pulmonary arterial hypertension, the presence of developmental lung disease, and the frequent association with chromosomal, genetic, and syndromal abnormalities. Treatment of children with PH requires a modified diagnostic algorithm tailored to childhood, as well as pathophysiologically oriented therapeutic strategies. In the current 2022 ERS/ESC-PH guidelines, the specific features of PH in children are highlighted in its own chapter and commented on by the authorship group in this article.

BACKGROUND: In recent years, there has been increasing evidence that asthma is associated with atherosclerosis and cardiovascular disease. However, data in children and adolescents are scarce and conflicting. We aimed to assess the impact of asthma with and without an allergic component on the carotid intima-media thickness in a large pediatric population. METHODS: The community-based early vascular ageing-Tyrol cohort study was performed between May 2015 and July 2018 in North, East (Austria) and South Tyrol (Italy) and recruited youngster aged 14 years and above. Medical examinations included anthropometric measurements, fasting blood analysis, measurement of the carotid intima-media thickness by high-resolution ultrasound, and a physician guided interview. RESULTS: The mean age of the 1506 participants was 17.8 years (standard deviation 0.90). 851 (56.5%) participants were female. 22 subjects had a physician diagnosis of non-allergic asthma, 268 had inhalative allergies confirmed by a positive radio-allergo-sorbent-test and/or prick test, and 58 had allergic asthma. Compared to healthy controls, participants with non-allergic asthma (411.7 vs. 411.7 µm; p = 0.932) or inhalative allergy (420.0 vs. 411.7 µm; p = 0.118) did not have significantly higher carotid intima-media thickness (cIMT). However, participants with allergic asthma had significantly higher cIMT (430.8 vs. 411.7; p = 0.004) compared to those without and this association remained significant after multivariable adjustment for established cardiovascular risk factors. CONCLUSION: Allergic asthma in the youth is associated with an increased carotid intima-media thickness. Physicians should therefore be aware of allergic asthma as a potential cardiovascular risk factor in children and adolescents. Trial Registration Number The EVA-Tyrol Study has been retrospectively registered at clinicaltrials.gov under NCT03929692 since April 29, 2019.

BACKGROUND AND AIMS: Ideal cardiovascular health (CVH) behaviors in adolescents are defined by body mass index (BMI), diet, physical activity and smoking, and are directly associated with better health in later life. To further improve health prevention programs we investigated the prevalence of these behaviors in a cohort of healthy adolescents and focused on the associations with sex, age, and education. METHODS AND RESULTS: The Early Vascular Aging Tyrol study is a cross-sectional study assessing 14- to 19-year-old pupils and apprentices in Western Austria and South Tyrol. Between May 2015 and July 2018 2047 adolescents (43.6% males, mean age 16.4 years) with complete data for all 4 health behaviors were included. The prevalence of ideal body mass index (BMI) was 78.3%, of ideal physical activity 42.5%, of non-smoking 70.4% and of ideal diet 8.1%. Females showed a higher smoking prevalence and a lower physical activity, but better dietary habits than males. Older adolescents of both sexes had lower prevalence of ideal smoking and diet. Apprentices and pupils of vocational schools had a higher BMI and a less favorable diet compared to secondary academic school students. Smoking prevalence was highest in apprentices. Non-ideal BMI was independently associated with smoking. CONCLUSION: In our cohort, only a minority showed ideal CVH behaviors which were best in adolescents younger than 16 years. We observed significant differences between males and females and a clear impact of school education with apprentices being at risk for non-ideal CVH behaviors.

OBJECTIVE: To assess the time point during infancy and early childhood at which greater than expected weight gain is associated with overweight in adolescence. STUDY DESIGN: Current height, weight, and body mass index (BMI) were assessed in 1520 adolescents (mean age of boys, 15.52 ± 0.84 years; mean age of girls, 15.37 ± 0.77 years). Information on weight and height trajectories during infancy and early childhood (birth and 6 other time points) was extracted from mother-child booklets. Conditional relative weights were computed to estimate greater or lower than expected weight gain (ie, soft tissue gain at a specific age independent of linear growth), and their association with BMI in adolescence was investigated using linear regression analysis. RESULTS: The mean BMI in adolescence was 21.77 ± 3.69 in boys and 21.70 ± 3.50 in girls. The proportion of overweight was 14.8% in each group. Overweight adolescents had significantly higher weight z-scores at birth, 1.2 month, 3.3 months, 7.6 months, 1 year, 2 years, and 4 years of age as compared with normal-weight adolescents. There were significant positive associations of weight z-scores and conditional relative weights with adolescent BMI at all ages except birth, which were strongest after the first year of life. In a majority of overweight adolescents, overweight had manifested within the first 4 years of life. CONCLUSIONS: Greater than expected weigh gain at any time in the first years of life is associated with an increased BMI in adolescence. The effect is strongest after the first year.

INTRODUCTION: Metabolomics studies are not routine when quantifying amino acids (AA) in congenital heart disease (CHD). OBJECTIVES: Comparative analysis of 24 AA in serum by traditional high-performance liquid chromatography (HPLC) based on ion exchange and ninhydrin derivatisation followed by photometry (PM) with ultra-high-performance liquid chromatography and phenylisothiocyanate derivatisation followed by tandem mass spectrometry (TMS); interpretation of findings in CHD patients and controls. METHODS: PM: Sample analysis as above (total run time, ~ 119 min). TMS: Sample analysis by AbsoluteIDQ® p180 kit assay (BIOCRATES Life Sciences AG, Innsbruck, Austria), which employs PITC derivatisation; separation of analytes on a Waters Acquity UHPLC BEH18 C18 reversed-phase column, using water and acetonitrile with 0.1% formic acid as the mobile phases; and quantification on a Triple-Stage Quadrupole tandem mass spectrometer (Thermo Fisher Scientific, Waltham, MA) with electrospray ionisation in the presence of internal standards (total run time, ~ 8 min). Calculation of coefficients of variation (CV) (for precision), intra- and interday accuracies, limits of detection (LOD), limits of quantification (LOQ), and mean concentrations. RESULTS: Both methods yielded acceptable results with regard to precision (CV < 10% PM, < 20% TMS), accuracies (< 10% PM, < 34% TMS), LOD, and LOQ. For both Fontan patients and controls AA concentrations differed significantly between methods, but patterns yielded overall were parallel. CONCLUSION: Serum AA concentrations differ with analytical methods but both methods are suitable for AA pattern recognition. TMS is a time-saving alternative to traditional PM under physiological conditions as well as in patients with CHD. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier NCT03886935, date of registration March 27th, 2019 (retrospectively registered).

BACKGROUND: According to the World Health Organization, cardiovascular diseases (CVDs) are the leading non-communicable cause of death. Awareness of the individual risk profile is crucial to implement a healthy lifestyle and prevent CVDs. Multiple studies demonstrated that atherosclerosis, the main cause of CVDs, begins early in life. Therefore, it may be necessary to start prevention programs already in childhood. METHODS: The EVA-Tyrol study is a population-based non-randomized controlled trial that will prospectively enroll 2000 participants from high schools and training companies in North- and East-Tyrol (Austria) and South-Tyrol (Italy). Participants will be assigned to either an intervention (n = 1500) or a control (n = 500) group. Intervention group participants will be enrolled at the 10th school grade (mean age 15-16 years), undergo two examinations within a two-year interval, with follow-up at the 12th grade (mean ages 17-18 years). Control group participants will be enrolled at the 12th grade (mean age 17-18 years). Medical examination will include anthropometric measurements, comprehensive lifestyle and dietary questionnaires, a fasting blood sample, high-resolution ultrasound of the carotid arteries, and measurement of carotid-femoral pulse wave velocity. Active intervention will consist of (1) enhancing knowledge about CVDs, (2) individual medical counseling based on the results of the baseline examination, (3) an online health promotion tool and (4) involvement of participants in planning and implementation of health promotion projects. Effectiveness of the intervention will be assessed by comparing the proportion subjects with ideal health metrics as defined by the American Heart Association between study groups. DISCUSSION: This study aims to improve cardiovascular health in Tyrolean adolescents by demonstrating the efficacy of a multi-layer health promotion program and may yield novel insights into the prevalence of vascular risk conditions and mechanisms of early vascular pathologies in adolescents. TRIAL REGISTRATION: EVA-Tyrol has been retrospectively registered at clinicaltrials.gov under NCT03929692 since April 29, 2019.

Prenatal closure of foramen ovale without CHD is a rarely reported entity. Therefore, clinical and echocardiographic findings are poorly defined in these patients. We report a patient with prenatal closure of foramen ovale that presented with severe pulmonary hypertension of the newborn and left ventricular failure. Judicious management strategies were utilised to successfully treat both life-threatening conditions.

BACKGROUND: The 6-minute walk test (6MWT) in children can be performed in the conventional way, or by using a measuring wheel. This study aimed to compare these test modalities and to determine influencing factors. METHODS: The study included 317 healthy children (172 boys) between 6 and 15 years from elementary schools and high schools, who were randomly assigned to perform a 6MWT either with or without a measuring wheel according to the guidelines of the American Thoracic Society. The 6-minute walk distance (6MWD) was compared between the two measuring modalities as well as different school types. RESULTS: The use of a measuring wheel during the 6MWT led to a significantly greater 6MWD compared to conventional walking. Students of sports schools walked substantially farther than those attending general high schools, irrespective of test modality. In multivariate regression analysis height, post-test heart rate, male sex and the measuring wheel itself were all independently associated with greater 6MWD. CONCLUSIONS: The use of a measuring wheel during a 6MWT reflects physical performance in children and adolescents more accurately as it includes the stretch of way around the cones during lap turns. Test modalities and sports background should be taken into account, especially when performing longitudinal monitoring and multicenter studies.

PURPOSE: Oral contraception is one of the most popular contraceptive methods both in adults and adolescents. However, the effects of oral contraception on lipids in adolescents are not well studied. METHODS: Lipid profiles were measured and contraceptive use was assessed in 14- to 19-year-old female participants of the prospective population-based Early Vascular Ageing-Tyrol Study between 2015 and 2018, twice on average 22 months apart. RESULTS: For this analysis, data from 828 young women with a median age of 17.0 years were available. Of them, 317 (38%) used oral contraceptives (OCs). OC users had a slightly higher systolic and diastolic blood pressure and larger changes over time and were more likely to use cigarettes than nonusers. Total cholesterol (179.6 vs. 162.4 mg/dL), low-density lipoprotein-cholesterol (106.4 vs. 94.6 mg/dL), and triglycerides (104.0 vs. 67.0 mg/dL) were significantly higher in OC users after multivariable adjustment in linear regression models. No difference in high-density lipoprotein-cholesterol between the two groups was found. In 558 females, follow-up data were available. Those who initiated OC use had on average 15.4 mg/dL higher low-density lipoprotein-cholesterol and 36.2 mg/dL higher triglyceride level changes between baseline and follow-up than never users. Duration of OC use did not show a significant association with lipid levels and changes. DISCUSSION: We showed an independent association between OC use and blood lipids as well as lipid trajectories over time in a large cohort of healthy adolescents. These changes are especially relevant to consider in adolescents with other risk factors for dyslipidemia or other cardiovascular risk factors.
RESUMEN
AIM: To assess the impact of maternal, neonatal, and adolescent factors on the development of non-alcoholic fatty liver disease (NAFLD) in a cohort of 14- to 19-year-old adolescents. METHODS: This study is part of the Early Vascular Ageing in the YOUth study, a single-center cross-sectional study conducted in western Austria. Maternal and neonatal factors were extracted from the mother-child booklet, adolescent factors were evaluated by a face-to-face interview, physical examination, and fasting blood analyses. Liver fat content was assessed by controlled attenuation parameter (CAP) using signals acquired by FibroScan® (Echosense, Paris, France). The association of maternal, neonatal, and adolescent factors with CAP values was analyzed using linear regression models. RESULTS: In total, 595 adolescents (27.2% male) aged 17.0 ± 1.3 years were included. 4.9% (n = 29) showed manifest NAFLD with CAP values above the 90th percentile. Male sex (p < 0.001), adolescent triglyceride levels (p = 0.021), Homeostatic Model Assessment for Insulin Resistance index and BMI z-score (p < 0.001, each) showed a significant association with liver fat content in the multivariable analysis. Maternal pre-pregnancy BMI was associated with CAP values after adjustment for sex, age, and birth weight for gestational age (p < 0.001), but this association was predominantly mediated by adolescent BMI (indirect effect b = 1.18, 95% CI [0.69, 1.77]). CONCLUSION: Components of the metabolic syndrome were the most important predictors of adolescent liver fat content. Therefore, prevention of NAFLD should focus on lifestyle modification in childhood and adolescence.

Background: Homocysteine (Hcy) has been associated with an adverse cardiovascular risk profile in adolescents. Assessment of the association between plasma Hcy levels and clinical/laboratory factors might improve our understanding of the pathogenesis of cardiovascular disease. Methods: Hcy was measured in 1,900 14- to 19-year-old participants of prospective population-based EVA-TYROL Study (44.3% males, mean age 16.4 years) between 2015 and 2018. Factors associated with Hcy were assessed by physical examination, standardized interviews, and fasting blood analysis. Results: Mean plasma Hcy was 11.3 ± 4.5â µmol/L. Distribution of Hcy was characterized by extreme right skew. Males exhibited higher Hcy and sex differences increased with increasing age. Univariate associations with Hcy emerged for age, sex, body mass index, high-density lipoprotein cholesterol, and for factors pertaining to blood pressure, glucose metabolism, renal function, and diet quality, whereas the most important multivariate predictors of Hcy were sex and creatinine. Discussion: Clinical and laboratory factors associated with Hcy in adolescents were manifold, with sex and high creatinine identified as strongest independent determinants. These results may aid when interpreting future studies investigating the vascular risk of homocysteine.
RESUMEN
(1) Background: Unhealthy dietary behaviors are estimated to be one of the leading causes of death globally and are often shaped at a young age. Here, we investigated adolescent diet quality and its predictors, including nutrition knowledge, in two large Central European cohorts. (2) Methods: In 3056 participants of the EVA-Tyrol and EVA4YOU prospective population-based cohort studies aged 14 to 19 years, diet quality was assessed using the AHEI-2010 and DASH scores, and nutrition knowledge was assessed using the questionnaire from Turconi et al. Associations were examined utilizing multivariable linear regression. (3) Results: The mean overall AHEI-2010 score was 42%, and the DASH score was 45%. Female participants (60.6%) had a significantly higher diet quality according to the AHEI-2010 and DASH score. AHEI-2010 and DASH scores were significantly associated (p < 0.001) with sex, school type, smoking, and total daily energy intake. The DASH score was additionally significantly associated (p < 0.001) with age, socioeconomic status, and physical activity. Participants with better nutrition knowledge were more likely to be older, to attend a general high school, to live in a high-income household, to be non-smokers, and to have a higher diet quality according to the AHEI-2010 and DASH score. (4) Conclusions: Predictors of better diet quality included female sex, physical activity, educational level, and nutrition knowledge. These results may aid focused interventions to improve diet quality in adolescents.

A 22-year-old woman with complete Fontan palliation for tricuspid valve hypoplasia and chronic anemia presented to a local hospital for swelling of her left arm. Initially, the patient was hemodynamically stable without dyspnea or chest pain. Admission hemoglobin was 53 g/L and D-dimer 0.51 mg/L. Sonography showed signs of venous congestion of the left arm, but no definitive signs of venous thrombosis. Subsequently she developed dyspnea with a decrease in transcutaneous oxygen saturation to 85%. Computed tomography angiography revealed bilateral pulmonary embolism with occlusion of the right pulmonary artery. The patient was transferred to a tertiary care center. Gastroscopy detected only small stomach ulcers, and because of ongoing hemodynamic instability, the decision was to initiate rescue ultrasound-assisted catheter-directed local thrombolysis. This treatment was effective with rapid hemodynamic stabilization without bleeding complications and without residual emboli in a long-term follow-up cardiac catheterization.
RESUMEN
OBJECTIVES: The aim of this retrospective study was to determine if Cormatrix® (CM) represents a safe alternative to conventional patch materials used in congenital heart surgery. METHODS: A total of 57 paediatric patients who underwent cardiac surgery using an Extracellular Matrix Bioscaffold (CM) were categorized into 4 groups according to the patch implant location. Patch-related complications and reintervention rates were analysed. A subgroup of 18 patients was subsequently compared to a matched group of 36 patients who underwent similar surgical procedures with autologous pericardium as patch material. RESULTS: No patient died during hospitalization. There were 2 late deaths, not related to the implanted CM patch. Fourteen (66.7%) out of 21 patients with arterial patch plasty developed progressive vessel/right ventricular outflow tract stenosis or aneurysm. All 3 patients with a valved CM conduit developed haemodynamically relevant valve stenosis or regurgitation. A total of 18 (31.5%) patients needed reintervention and 12 (21.1%) related to CM. Four (7%) patients needed surgical treatment with operative removal of the stenosis. Redo valve replacement was performed on 2 (3.5%) patients. Six (10.5%) patients required an interventional cardiology procedure at a median interval of 5 months from surgery. The subgroup analysis revealed a significantly lower patch-related reintervention rate in patients treated with autologous pericardium when compared to CM (P = 0.006). CONCLUSIONS: CM is safe for atrial and ventricular defect closure. The use of CM for arterial vessel reconstruction is associated with higher reintervention rates when compared to autologous pericardium.
