RESUMEN
Purpose The measurement of fetal cardiovascular function parameters is not yet established in prenatal diagnostics. Now that the research field of fetal programming is becoming increasingly important, this might change. Fetal cardiovascular changes have been described above all in early/severe fetal growth restriction (FGR). The aim of this study was to investigate functional echocardiographic parameters in fetuses with late-onset small for gestational age (SGA)/FGR. Materials and methods A prospective cohort of SGA fetuses (including FGR) and a control group with similar distribution of gestational age were studied. Parameters of systolic, diastolic and global cardiac function, morphometry and measurements of the fetal abdominal aorta were collected. Results A total of 149 SGA fetuses and 143 control fetuses were included from 32 weeks until term. The total SGA group was further divided into SGA 3rd-10th (fetuses between the 3rd and 10th weight percentile) and FGR subgroups. In the total SGA group, relative right and left ventricular wall thickness, left E/A ratio, isovolumetric contraction time and left myocardial performance index were significantly increased compared to controls after adjustment for gestational age. MAPSE, TAPSE, ejection time, left cardiac output and abdominal aortic distensibility were significantly lower. The changes were more pronounced in the FGR subgroup. Conclusion Even in a group of late-onset SGA/FGR situation, echocardiographic parameters are already altered in utero. Zusammenfassung Ziel Die Messung fetaler kardiovaskulärer Funktionsparameter ist in der Pränataldiagnostik noch nicht etabliert. Nachdem das Forschungsgebiet der fetalen Programmierung einen immer höheren Stellenwert hat, könnte sich das bald ändern. Vor allem bei früher fetaler Wachstumsrestriktion (FGR) sind kardiovaskuläre Veränderungen beschrieben. Ziel dieser Studie war es dies bei Feten mit spät einsetzender FGR zu untersuchen. Material und Methode Eine prospektive Kohorte von Feten, die zu klein für das Gestationsalter (SGA) sind (einschließlich FGR) sowie eine Kontrollgruppe ähnlichen Gestionsalters wurden untersucht. Es wurden Parameter der systolischen, diastolischen sowie globalen Herzfunktion, der Morphometrie sowie Messungen der fetalen Aorta abdominalis erhoben. Ergebnisse Insgesamt wurden 149 SGA Feten sowie 143 Kontrollfeten ab 32 Schwangerschaftswochen eingeschlossen. Die Gesamt-SGA Gruppe wurde für eine Subgruppenanalyse weiterhin in eine SGA (SGA 3-10: Feten zwischen der 3. und 10. Gewichtsperzentile) sowie eine FGR Subgruppe unterteilt. In der Gesamt-SGA Gruppe zeigten sich im Vergleich zu den Kontrollen nach Adjustierung an das Gestationsalter die relative rechte sowie linke Ventrikelwanddicke, das linke E/A-Verhältnis, die isovolumetrische Kontraktionszeit und der linke myokardiale Performanceindex signifikant erhöht. MAPSE, TAPSE, die Ejektionszeit, das linke Herzzeitvolumen und die Beweglichkeit der Aorta abdominalis waren signifikant geringer. Die Ergebnisse waren im Subgruppenvergleich in der FGR Subgruppe ausgeprägter. Schlussfolgerung Auch in einer Gruppe spät einsetzender SGA/FGR Situation sind echokardiographische Parameter bereits intrauterin verändert.
RESUMEN
BACKGROUND: Exercise training improves peak oxygen uptake (V.O2peak) in heart failure with preserved ejection fraction (HFpEF). Multiple adaptations have been addressed, but the role of circulating endothelium-repairing cells and vascular function have not been well defined. OBJECTIVES: The authors investigated effects of moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on vascular function and repair in HFpEF. METHODS: This study is a subanalysis of the OptimEx-Clin (Optimizing Exercise Training in Prevention and Treatment of Diastolic Heart Failure) study randomizing patients with HFpEF (n = 180) to HIIT, MICT, or guideline control. At baseline, 3, and 12 months, the authors measured peripheral arterial tonometry (valid baseline measurement in n = 109), flow-mediated dilation (n = 59), augmentation index (n = 94), and flow cytometry (n = 136) for endothelial progenitor cells and angiogenic T cells. Abnormal values were defined as outside 90% of published sex-specific reference values. RESULTS: At baseline, abnormal values (%) were observed for augmentation index in 66%, peripheral arterial tonometry in 17%, flow-mediated dilation in 25%, endothelial progenitor cells in 42%, and angiogenic T cells in 18%. These parameters did not change significantly after 3 or 12 months of HIIT or MICT. Results remained unchanged when confining analysis to patients with high adherence to training. CONCLUSIONS: In patients with HFpEF, high augmentation index was common, but endothelial function and levels of endothelium-repairing cells were normal in most patients. Aerobic exercise training did not change vascular function or cellular endothelial repair. Improved vascular function did not significantly contribute to the V.O2peak improvement after different training intensities in HFpEF, contrary to previous studies in heart failure with reduced ejection fraction and coronary artery disease.

PURPOSE: Aorto-left ventricular tunnel (ALVT) is an extremely rare, albeit prenatally detectable, extracardiac channel that connects the ascending aorta to the cavity of the left ventricle. MATERIALS AND METHODS: All ALVTs diagnosed prenatally (2006-2020) in five tertiary referral centers were retrospectively assessed for prenatal ultrasound findings, intrauterine course, postnatal outcome, and surgical treatment. We focused on the size of the tunnel and alterations of perfusion of the left ventricular outflow tract and aortic arch. RESULTS: 11 fetuses were diagnosed with ALVT at a mean gestational age of 24.8 weeks. All cases were associated with severe dilatation of the left ventricle and a to-and-fro flow in the left outflow tract. Signs of congestive heart failure were present in five fetuses, four of which were terminated and one of which died in the neonatal period. One fetus died in utero at 34 weeks without prior signs of cardiac failure. Of the five survivors, two underwent the Ross procedure. In both cases the prenatal left ventricular outflow was exclusively via a large tunnel. The remaining three neonates underwent patch closure of the tunnel. In these cases, the prenatal outflow of the left ventricle was via the aortic valve and simultaneously over the tunnel. CONCLUSION: Prenatal diagnosis of ALVT should be considered in the presence of left ventricular hypertrophy, dilatation of the aortic root, and to-and-fro flow in the aortic outflow tract. Signs of heart failure are associated with an unfavorable outcome. Large tunnels, particularly in combination with the absence of flow over the aortic valve, may be an unfavorable predictor of surgical repair.

PURPOSE: To describe the perinatal outcome of a prospective cohort of late-onset small-for-gestational-age (SGA) fetuses and to test adverse perinatal outcome (APO) prediction using Doppler measurements. METHODS: Singleton pregnancies from 32 weeks with suspicion of SGA (followed-up each 2 weeks) and randomly selected healthy controls at a university hospital were included. The whole SGA group was divided into the FGR subgroup or SGA percentile 3-10 subgroup.âThe following Doppler measurements were evaluated prospectively: umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, cerebro-placental ratio (CPR), and mean uterine artery (mUtA) PI. APO was defined as arterial cord blood pH ≤â7.15 and/or 5-minute Apgar ≤â7 and/or emergency operative delivery and/or admission to the neonatal unit. Induction of labor was indicated according to a stage-based protocol. RESULTS: A total of 149 SGA and 143 control fetuses were included. The number of operative deliveries was similar between both groups (control: 29â%, SGA: 28â%), especially the cesarean delivery rate after the onset of labor (11â% vs. 10â%). Most SGA cases ended up in induction of labor (61â% vs. 31â%, pâ<â0.001). The areas under the curve (AUC) for APO prediction were similar using the last UA PI, MCA PI, CPR, and mUtA PI and barely reached 0.60. The AUC was best for the FGR subgroup, using the minimal CPR or maximum mUtA PI z-score of all longitudinal measurements (AUCâ=â0.63). CONCLUSION: SGA fetuses do not have a higher rate of operative delivery if managed according to a risk stratification protocol. Prediction of APO is best for SGA and FGR using the "worst" CPR or mUtA PI but it remains moderate.

BACKGROUND: Congenital heart defects (CHD) affect about 8 out of 1000 births worldwide. Most of the patients reach adulthood and are exposed to an increased risk of endocarditis. Since bacteria already enter the bloodstream during everyday activities, oral hygiene is given special importance in the prevention of endocarditis. METHODS: In this study 81 boys (55.1%) and 66 (44.9%) girls with CHD received a dental exam and additionally an assessment using the DIAGNOdent® pen. This study group consisting of patients with CHD was matched with a healthy epidemiological control group in Germany. RESULTS: Eighty-one boys (55.1%) and 66 (44.9%) girls were examined. The mean age was 11 ± 4 years. 38.8% showed at least one untreated carious lesions. 37.4% had a dmft/DMFT ≥2 and thus represented a group with an increased caries risk. The dmft value was 2.12 ± 1.25 in the age group 3-6 year olds. In the group of the 7-12 year old patients the DMFT/dmft was 2.06 ± 2.27, whereas DMFT in 13-17 year olds was at 2.12 ± 1.58. However, children and adolescents with CHD had a higher DMF index than healthy children in the same age group. CONCLUSIONS: The present study reveals that more than one third of those examined have a dental condition in need of rehabilitation. In future, close interdisciplinary cooperation between pediatric cardiologists and dentists should ensure regular dental check-ups.

OBJECTIVE: This study compared objectively measured and self-reported physical activity (PA) in adults with congenital heart disease (ACHD) to a healthy reference cohort (RC). PATIENTS AND METHODS: From May 2017 to August 2020, 211 ACHD (39.9 ± 9.7 years, 101 female) and 141 healthy adults (35.9 ± 14.7 years, 76 female) participated in a wearable-based and self-reported PA assessment. Moderate-to-vigorous PA (MVPA) and the step count were recorded with the Garmin vivofit® 3 device for 7 consecutive days. Additionally, subjects were asked to report the number of days they are active for ≥30 min throughout the week. RESULTS: Only 33 (17%) ACHD and 36 (26%) healthy controls (p = 0.030) accumulated the World Health Organization's (WHO) recommendation of 150 min MVPA per week. ACHD were less active per week (ACHD: 40.0 [0.0; 101.0] min. MVPA vs. RC: 75.0 [22.5; 152.5] min. MVPA, p = 0.002) and walked fewer daily steps (ACHD: 8,246 [6,505; 10,434] vs. RC: 9,413 [7,621; 11,654], p = 0.001) than healthy controls. Especially, patients with moderate (p = 0.030), complex (p < 0.001), or surgically corrected (p = 0.008) congenital heart disease accumulated significantly less MVPA than healthy peers throughout the week. A large majority of 72% of ACHD and 58% of the RC overestimated their weekly active days by more than one day. CONCLUSIONS: ACHD walked quite a few steps daily but lacked intensity. ACHD was less active than healthy controls and failed to reach international recommendations. They therefore need encouragement toward more intense movement to improve the exercise capacity and lower cardiovascular risk. Self-reported PA showed no agreement to the objectively measured PA.

OBJECTIVES: An association between fetal growth restriction (FGR) and increased predisposition to cardiovascular disease (CVD) is suggested. The aim of this study was to evaluate subclinical signs of fetal cardiac remodeling in late-onset small-for-gestational-age (SGA) and growth-restricted fetuses using two-dimensional speckle tracking echocardiography (2D-STE). METHODS: This is a prospective cohort study, including 117 late-onset (≥32 weeks) SGA (birthweight≤10th centile) fetuses and 102 gestational age matched controls. A subgroup analysis was performed: FGR was defined based on either BW (

OBJECTIVE: Patients with tetralogy of Fallot (ToF) have limited pulmonary blood flow before corrective surgery and ongoing dysfunction of the pulmonary valve and right ventricle throughout life leading to lower exercise capacity and lung volumes in many patients. Inhalation training can increase lung volumes, improve pulmonary blood flow and consequently exercise capacity. This study tests whether home-based daily breathing training improves exercise capacity and lung volumes. METHODS: From February 2017 to November 2018, 60 patients (14.7±4.8 years, 39% female) underwent spirometry (forced vital capacity (FVC); forced expiratory volume in 1 s (FEV1)), cardiopulmonary exercise testing (peak oxygen uptake (peak [Formula: see text]O2)) and breathing excursion measurement. They were randomised into immediate breathing exercise or control group (CG) and re-examined after 6 months. The CG started their training afterwards and were re-examined after further 6 months. Patients trained with an inspiratory volume-oriented breathing device and were encouraged to exercise daily. The primary endpoint of this study was the change in peak [Formula: see text]O2. Results are expressed as mean±SEM (multiple imputations). RESULTS: In the first 6 months (intention to treat analysis), the training group showed a more favourable change in peak [Formula: see text]O2 (Δ0.5±0.6 vs -2.3±0.9 mL/min/kg, p=0.011), FVC (Δ0.18±0.03 vs 0.08±0.03 L, p=0.036) and FEV1 (Δ0.14±0.03 vs -0.00±0.04 L, p=0.007). Including the delayed training data from the CG (n=54), this change in peak [Formula: see text]O2 correlated with self-reported weekly training days (r=0.282, p=0.039). CONCLUSIONS: Daily inspiratory volume-oriented breathing training increases dynamic lung volumes and slows down deconditioning in peak [Formula: see text]O2 in young patients with repaired ToF.

OBJECTIVES: Grip strength is known to be reduced in adults with congenital heart disease (CHD). This study compared grip strength in paediatric patients with CHD with healthy controls and determined a possible association between grip strength and health-related physical fitness (HRPF). METHODS: Grip strength and HRPF were assessed in 569 children (12.4 years, 95% CI 12.16 to 12.72; 238 girls) with various CHD and compared with 2551 healthy controls (11.4 years, 95% CI 11.3 to 11.5; 1424 girls). Grip strength was determined as the maximum value of three repetitions with each hand. HRPF was tested by five motor tasks (FITNESSGRAM) and converted into an SD score (z-score). RESULTS: After adjusting for age, sex and weight, children with CHD showed significantly lower grip strength compared with healthy controls (CHD: 20.8 kg, 95% CI 20.4 to 21.2; controls: 24.5 kg, 95% CI 24.3 to 24.8). CHD subgroup analysis also revealed significantly lower grip strength than the controls, with the lowest values in patients with total cavopulmonary connection (19.1, 95% CI 18.0 to 20.2). Children with complex CHD showed the lowest values with 19.8 kg (95% CI 19.2 to 20.4), those with moderate 20.7 kg (95% CI 19.9 to 21.4) and those with simple 22.5 kg (95% CI 21.6 to 23.3), respectively. HRPF was also lower (z-score: -0.46, 95% CI -0.49 to -0.35) compared with healthy controls and poorly associated with grip strength (r=0.21). CONCLUSIONS: Grip strength is already reduced in children with CHD and poorly associated with HRPF. This suggests that grip strength and HRPF are different domains and have to be assessed separately.

OBJECTIVE: This cross-sectional study aimed to determine whether there is an association between objectively assessed physical activity (PA) and health-related quality of life (HRQoL) in children with CHD. PATIENTS AND METHODS: From September 2017 to January 2021, 343 children with CHD (12.1 ± 3.3 years, 135 girls) provided valid PA data after a 7-day objective PA assessment. PA was evaluated as average daily steps and moderate-to-vigorous physical activity (MVPA) minutes assessed via wearable bracelet Garmin vivofit Jr. These children also completed the KINDL - a 24 Likert-scaled item questionnaires assessing HRQoL in the six dimensions physical well-being, emotional well-being, self-esteem, family, friends and everyday functioning. RESULTS: Daily Steps (r = 0.166, P = .003) and daily MVPA minutes (r = 0.134, P = .017,) were both correlated to total KINDL score. Furthermore, both steps and MVPA were associated with the subscales physical well-being (steps: r = 0.165 p=.003; MVPA: r = 0.129, P = .022), friends (steps: r = 0.210, P < .001, MVPA: r = 0.179, P = .001), steps, and to everyday functioning (r = 0.142, P = .012). Logistic regression showed each MVPA minute increase conferred to a 1% increase in reporting better HRQoL (OR: 1.009 [95% CI: 1.002 - 1.017], P = .019). CONCLUSIONS: PA was positively associated with HRQoL in children with CHD. Patients who move more are more likely to report better HRQoL. While the magnitude of this association needs to be further understood, continuous encouragement towards more PA seems to be crucial in a holistic approach to medical aftercare in children with CHD.

BACKGROUND: Although cardiovascular rehabilitation (CR) is well accepted in general, CR-attendance and delivery still considerably vary between the European countries. Moreover, clinical and prognostic effects of CR are not well established for a variety of cardiovascular diseases. METHODS: The guidelines address all aspects of CR including indications, contents and delivery. By processing the guidelines, every step was externally supervised and moderated by independent members of the "Association of the Scientific Medical Societies in Germany" (AWMF). Four meta-analyses were performed to evaluate the prognostic effect of CR after acute coronary syndrome (ACS), after coronary bypass grafting (CABG), in patients with severe chronic systolic heart failure (HFrEF), and to define the effect of psychological interventions during CR. All other indications for CR-delivery were based on a predefined semi-structured literature search and recommendations were established by a formal consenting process including all medical societies involved in guideline generation. RESULTS: Multidisciplinary CR is associated with a significant reduction in all-cause mortality in patients after ACS and after CABG, whereas HFrEF-patients (left ventricular ejection fraction <40%) especially benefit in terms of exercise capacity and health-related quality of life. Patients with other cardiovascular diseases also benefit from CR-participation, but the scientific evidence is less clear. There is increasing evidence that the beneficial effect of CR strongly depends on "treatment intensity" including medical supervision, treatment of cardiovascular risk factors, information and education, and a minimum of individually adapted exercise volume. Additional psychologic interventions should be performed on the basis of individual needs. CONCLUSIONS: These guidelines reinforce the substantial benefit of CR in specific clinical indications, but also describe remaining deficits in CR-delivery in clinical practice as well as in CR-science with respect to methodology and presentation.
RESUMEN
BACKGROUND: The number of adults with congenital heart disease (ACHD) is steadily rising due to increased survival rate and improved medical resources. Accordingly, more than 330,000 ACHD are currently living in Germany. Almost all of them require lifelong specialized medical follow-up for their chronic heart disease, often accompanied by residua, sequelae, or comorbidities. Primary care physicians (PCPs) are a crucial factor in directing patients to ACHD specialists or specialized institutions, but despite all efforts, the number of ACHD under specialized care is low, the lost-to-follow-up rate is high, and the morbidity and mortality is substantial. The present cross-sectional study was designed to systematically characterize the health care of ACHD from a patient perspective, including (I) use of medical care by ACHD, (II) medical counselling needs, and (III) perceived satisfaction with health care. METHODS: The German-wide analysis was based on a 25-item questionnaire designed to address different aspects of medical status and health issues of ACHD from their own perspective, performed between May of 2017 and July of 2020. RESULTS: A total of 4,008 ACHD (52% female; mean age 41.9±17.2 years) completed the questionnaire. The majority of ACHD (3,524, 87.9%) reported, that they consulted their PCP for non-cardiac health problems, and 49.7% (n=1,991) consulted their PCP also for medical problems associated with the underlying CHD. Almost all ACHD reported a need for medical advice concerning exercise capacity and daily life activities, occupational skills, pregnancy, rehabilitation, genetic counselling, insurance, and retirement. A total of 1,840 (45.9%) patients were not aware of the existence of certified ACHD specialists or centers. Moreover, 2,552 (67.6%) of those surveyed were uninformed about patient organizations for ACHD. CONCLUSIONS: The present study demonstrates that ACHD are largely uninformed about the ACHD care structures available nationwide, although the patients have a great need for specialized follow-up, advice, and care.
RESUMEN
An athlete's skin has to cope with various stressors that influence skin integrity. This study investigated the effect of intense sporting activity at a competitive level on skin health, independent of the type of sport. The prevalence of dermatoses in elite athletes who exercise 8 or more hours per week was compared to recreational athletes. By applying a questionnaire, we acquired data from n=492 recruited athletes and recreational athletes regarding the prevalence of dermatoses, the extent of physical activity, and sports discipline practiced. Compared to the reference group, elite athletes showed less inflammatory, traumatic, infectious, and sebaceous skin diseases and especially neurodermitis, pruritus, bullae, tinea pedis, acne, and herpes were less common. Women suffered from skin diseases more often than men. With advanced age, the incidence of dermatoses increased, but less so among elite athletes. The discipline practiced and the duration of training, especially when performed outdoors, strongly influenced the development of dermatoses. Even though the skin of athletes is exposed to higher stress levels and physical strain, we can state that intensive physical activity seems to act as a protecting factor against skin diseases and significantly promotes skin health.

BACKGROUND: Keratinocyte cancers, also referred to as non-melanoma skin cancers (NMSCs), are one of the most common malignant skin tumors. We performed a retrospective analysis of lesions from patients of a private dermatology practice to evaluate the use of electrical impedance spectroscopy (EIS) in detecting keratinocyte malignancies. The aim of the study is to assess the accuracy of the technique and to rate its use as supportive tool in NMSC diagnosis. MATERIAL AND METHODS: The period evaluated ranges from September 2015 to November 2019. In total, 1712 lesions from 951 patients were included. All lesions suspicious for malignancy were gauged with the Nevisense device. Excised lesions were sent in for histopathological classification, and the results were compared to the Nevisense score. RESULTS: A total of 767 lesions (44.8%) received a negative score (0-3) from the Nevisense system and 945 lesions (55.2%) a positive score (4-10). The combination of the dermatologist's visual assessment plus the technical determined Neviscore resulted in the excision of 52.5% of all 1712 suspicious lesions whereof 15% were found to be malignant. The sensitivity of Nevisense was 98.4% for NMSC detection. CONCLUSION: Electrical impedance spectroscopy was found to be a valuable adjunct support tool in clinical decisions for cases with suspicion for NMSC.

BACKGROUND: The shift toward a preventative approach in medical aftercare of congenital heart disease (CHD) patients has led to encouragement of regular physical activity (PA) in this patient population. Objective measures are crucial in accurately displaying PA levels and have increasingly found their way into clinical research. This review aims to give an overview about quality, methodology, and outcomes of current scientific work on accelerometers objectively assessing PA in patients with CHD. METHODS: Systematically researched literature in all relevant databases (PubMed, Cochrane, and Scopus) over the past decade (2009-2019) with history of CHD and accelerometer-based PA assessment was evaluated by 2 independent reviewers according to the Study Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies of the National Heart, Lung, and Blood Institute. RESULTS: Eight articles with 664 pediatric patients with CHD aged 3-18 years (range 10-162 patients), 5 studies with 574 adults with CHD aged 18-63 years (range 28-330 patients), and 3 studies with 177 pediatric patients and adults with CHD aged 8-52 years were included. Two studies were rated "good"; 9, "fair"; and 5, "poor." Methodologies and devices differed substantially across all studies. CONCLUSIONS: Overall study quality was fair at best, and due to difficult methodological comparability of the studies, no clear answer on how active patients with CHD really are can currently be given. Larger studies carefully considering collection and processing criteria, and correct reporting standards exploring PA in patients with CHD from different angles are needed.

BACKGROUND: The number of adults with congenital heart disease (ACHD) is steadily increasing. Over their life-time, many of the affected patients require medical rehabilitation after interventional or surgical treatment of residua, sequels or complications of their congenital heart defect (CHD). However, up to now only scarce data exist about indication, performance and outcomes of cardiac rehabilitation in ACHD. METHODS: The course and outcome of rehabilitation after previous interventional or surgical treatment in ACHD was analyzed in a retrospective cohort study. RESULTS: Two hundred and five ACHD {54% female; mean age 34±12 [16-68] years} with mild (23.9%), moderate (35.1%) or severe CHD (41.0%), of whom 32% had complex CHD, 21% right-ventricular outï¬ow tract obstructions, 20% pre-tricuspid shunts, 18% left heart or aortic anomalies, 9% post-tricuspid shunts and 2% other congenital cardiac anomalies were included into analysis. The main indications for rehabilitation were a preceding surgical (92%) or interventional (3%) treatment of the underlying CHD immediately before rehabilitation. During rehabilitation, no severe complications occurred. The number of patients in function class I/II increased from 189 to 200 and decreased in class III/IV from 16 to 5. Cardiac medication could be reduced or stopped after rehabilitation in 194 patients, with the exception of ACE-inhibitors. There was an improvement in cardiovascular risk factors. While before medical treatment 77% (n=157) patients were capable of working, the number increased to 82% [168] at the end of rehabilitation. Throughout a follow-up 9.3% (n=19) of patients needed further cardiac interventions. CONCLUSIONS: The current study provided for the first time comprehensive data on the course of rehabilitation in a large cohort of ACHD after surgical or interventional treatment. The overall outcome of ACHD after rehabilitation was uneventful and favorable. Further research is required to assess the clinical long-term outcome, the impact of rehabilitation on the quality of life, disease coping and employment. The results of this study can serve as a benchmark for the development of speciï¬c rehabilitation programs in ACHD.
RESUMEN
PURPOSE: The study aimed to investigate the role of training load characteristics and injury and illness risk in youth ski racing. METHODS: The training load characteristics as well as traumatic injuries, overuse injuries, and illnesses of 91 elite youth ski racers (ageâ¯=â¯12.1 ± 1.3 years, mean ± SD) were prospectively recorded over a period of 1 season by using a sport-specific online database. Multiple linear regression analyses were performed to monitor the influence of training load on injuries and illnesses. Differences in mean training load characteristics between preseason, in-season, and post-season were calculated using multivariate analyses of variance. RESULTS: Differences were discovered in the number of weekly training sessions (pâ¯=â¯0.005) between pre-season (4.97 ± 1.57) and post-season (3.24 ± 0.71), in the mean training volume (pâ¯=â¯0.022) between in-season (865.8 ± 197.8 min) and post-season (497.0 ± 225.5 min) and in the mean weekly training intensity (Index) (pâ¯=â¯0.012) between in-season (11.7 ± 1.8) and post-season (8.9 ± 1.7). A total of 185 medical problems were reported (41 traumatic injuries, 12 overuse injuries, and 132 illnesses). The weekly training volume and training intensity was not a significant risk factor for injuries (p > 0.05). Training intensity was found to be a significant risk factor for illnesses in the same week (ßâ¯=â¯0.348; pâ¯=â¯0.044; R²â¯=â¯0.121) and training volume represents a risk factor for illnesses in the following week (ßâ¯=â¯0.397; pâ¯=â¯0.027; R²â¯=â¯0.157). CONCLUSION: A higher training intensity and volume were associated with increased illnesses, but not with a higher risk of injury. Monitoring training and ensuring appropriate progression of training load between weeks may decrease incidents of illness in-season.

PURPOSE: Current research indicates an imbalance in the autonomic nervous system (ANS) pathway activities in patients with congenital heart disease (CHD). The heart rate variability (HRV) is a measure to quantify activities of the parasympathetic and sympathetic branches. This study evaluated the parasympathetic activity by means of HRV in patients with CHD, regarding diagnostic subgroups and CHD severity, and the association to exercise capacity. METHODS: From July 2016 to August 2018, a total of 222 patients with different types of CHD (28.4 ± 10.1 yr; 44% female) received breathing-controlled HRV measurement in the supine position. Based on 130 adjacent heartbeats, the root mean square of successive differences (RMSSD), a parasympathetic activity surrogate was estimated and log-transformed. Additionally, all patients underwent a cardiopulmonary exercise test. For comparison, a control group (CG) of 57 (29.0 ± 7.1 yr; 61% female) healthy volunteers was recruited. RESULTS: Patients with CHD exhibited reduced parasympathetic activity in comparison to the CG (lnRMSSD CHD: 3.55 ± 0.57 ms vs CG: 3.93 ± 0.55 ms; P < .001), with the lowest parasympathetic activity in patients with Fontan circulation (3.07 ± 0.54 ms; P < .001). Complex CHD (3.40 ± 0.54 ms) had worse values compared with patients with simple (3.87 ± 0.55 ms; P < .001) and moderate severity (3.74 ± 0.54 ms; P < .001). Better parasympathetic activity in CHD patients was associated with increased exercise capacity (r = 0.322; P < .001). CONCLUSIONS: Impaired parasympathetic activity suggests limited function of the ANS in patients with CHD. Further studies should focus on the association of exercise capacity and ANS to possibly improve parasympathetic activity and functional outcomes.

Improved clinical care has led to an increase in the number of adults with congenital heart disease (CHD) engaging in leisure time and competitive sports activities. Although the benefits of exercise in patients with CHD are well established, there is a low but appreciable risk of exercise-related complications. Published exercise recommendations for individuals with CHD are predominantly centred on anatomic lesions, hampering an individualized approach to exercise advice in this heterogeneous population. This document presents an update of the recommendations for competitive sports participation in athletes with cardiovascular disease published by the Sports Cardiology & Exercise section of the European Association of Preventive Cardiology (EAPC) in 2005. It introduces an approach which is based on the assessment of haemodynamic, electrophysiological and functional parameters, rather than anatomic lesions. The recommendations provide a comprehensive assessment algorithm which allows for patient-specific assessment and risk stratification of athletes with CHD who wish to participate in competitive sports.

BACKGROUND: Physical activity (PA) has a substantial impact on arterial stiffness in adults; however, evidence regarding children is scarce. The aim of this study was to examine the association between objectively measured PA with different intensities and surrogate measures of arterial stiffness in healthy children. METHODS: Altogether, 80 children (41 girls and 39 boys, ranging from 8-11 y) participated in this prospective, cross-sectional study. Sedentary time and PA of light, moderate, and vigorous intensity levels were measured over a period of 7 days by accelerometry. Arterial stiffness parameters, including pulse wave velocity and central systolic blood pressure (cSBP), were noninvasively assessed by the oscillometric Mobil-O-Graph. Associations were tested using multiple linear regressions with adjustments for potential confounders (α ≤ .05). RESULTS: PA of moderate intensity was negatively associated with cSBP (ß = -0.266, P = .017). PA of vigorous intensity was inversely related to pulse wave velocity (ß = -0.225, P = .045) and cSBP (ß = -0.286, P = .010), respectively. CONCLUSION: Higher time spent in PA of moderate and vigorous intensity is associated with reduced pulse wave velocity and lower cSBP values in children. It suggests that PA is a favorable determinant of arterial health.
