An efficient ghost-cell immersed boundary method (GCIBM) for simulating turbulent flows in complex geometries is presented. A boundary condition is enforced through a ghost cell method. The reconstruction procedure allows systematic development of numerical schemes for treating the immersed boundary while preserving the overall second-order accuracy of the base solver. Both Dirichlet and Neumann boundary conditions can be treated. The current ghost cell treatment is both suitable for staggered and non-staggered Cartesian grids. The accuracy of the current method is validated using flow past a circular cylinder and large eddy simulation of turbulent flow over a wavy surface. Numerical results are compared with experimental data and boundary-fitted grid results. The method is further extended to an existing ocean model (MITGCM) to simulate geophysical flow over a three-dimensional bump. The method is easily implemented as evidenced by our use of several existing codes.

Home-based exercise training is a promising alternative to conventional supervised training for patients with congenital heart disease (CHD). Even though the beneficial effect of exercise interventions is well established in patients with CHD, knowledge concerning variety and utility of existing programmes is still lacking. Therefore, the aim of this review is to give an overview about existing home-based exercise interventions in patients with CHD. A systematic search was performed in PubMed, Cochrane, Scopus and PEDro (2008–2018) for relevant clinical trials that provided any kind of home-based exercise with patients with CHD. All articles were identified and assessed by two independent reviewers. Seven articles with 346 paediatric CHD (18 months to 16 years) and five articles with 200 adults with CHD (21–41 years) were included. Most studies performed a supervised home-based exercise intervention with children and adolescents exercising at least three times per week with duration of 45 min for 12 weeks. Reported outcome measurements were health-related quality of life and physical activity, but mostly exercise capacity measured as peak oxygen uptake that improved in four studies (1.2%, 7%, 7.7%, 15%; p

Aim

Health-related quality of life (HrQoL) is a multidimensional concept including self-reported measures of physical and mental health. Throughout the last decades, HrQoL has become a more and more important outcome measure not only in clinical conditions. This study evaluates current HrQoL of healthy children and adolescents, determinants of HrQoL, and the agreement between self- and proxy-report.



Methods

From April 2012 to July 2013, we prospectively examined 530 healthy children (13.2 ± 2.1 years, 236 girls) and their parents on their childrens HrQoL using the KINDL-R self-report questionnaire and the parent's proxy-report. Data was compared to the established reference value from 2007 and the agreement of self- and parent's proxy-report was assessed by calculation of intraclass correlation coefficient (ICC).



Results

In general, the HrQoL improved compared to references in both children's (104.5 ± 12.6 % of predicted reference value, P < .001) and parent's proxy-report (104.3 ± 12.3 % of predicted reference value, P < .001). HrQoL declined with proceeding age (r = −.247, P < .001) but was not associated with BMI (r = −.035, P = .420). There was good accordance between children's reported HrQoL and the parent's proxy-report (ICC: .774). Only in the domains ‘self-esteem’ (ICC: .558) and ‘Emotional well-being’ (ICC: .612) the agreements were moderate.



Conclusions

HrQoL perception has increased throughout the past 10 years and worsens with increasing age. Moreover, the parent's proxy-report of the KINDL-R questionnaire is a good supplementary method to provide additional information regarding to children's HrQoL.

Health-related quality of life in children and adolescents: Current normative data, determinants and reliability on proxy-report.

Background: Overweight and obesity have become a major public health concern in recent decades, particularly in patients with chronic health conditions like congenital heart disease (CHD). This systematic review elaborates on the prevalence and the longitudinal development of overweight and obesity in children and adults with CHD. Methods: A systematic literature search was conducted in PubMed, Cochrane, and Scopus from January 2010 to December 2020 on overweight and obesity prevalence in children and adults with CHD. Results: Of 30 included studies, 15 studies evaluated 5680 pediatric patients with CHD, 9 studies evaluated 6657 adults with CHD (ACHD) and 6 studies examined 9273 both pediatric patients and ACHD. Fifteen studies received the quality rating “good”, nine studies “fair”, and six studies “poor”. In children with CHD, overweight prevalence was between 9.5–31.5%, and obesity prevalence was between 9.5–26%; in ACHD, overweight prevalence was between 22–53%, and obesity was between 7–26%. The prevalence of overweight and obesity was thereby similar to the general population. Overweight and obesity have been shown to increase with age. Conclusion: The prevalence of overweight and obesity in children and adults with CHD is similar to the general population, demonstrating that the growing obesity pandemic is also affecting the CHD population.
