Abstract
Hypertrophic cardiomyopathy (HCM) often leads to heart failure. Mutations in sarcomeric proteins are most frequently the cause of HCM but in many patients the gene defect is not known. Here we report on a young man who was diagnosed with HCM shortly after birth. Whole exome sequencing revealed a mutation in the FLNC gene (c.7289C > T; p.Ala2430Val) that was previously shown to cause aggregation of the mutant protein in transfected cells. Myocardial tissue from patients with this mutation has not been analyzed before and thus, the underlying etiology is not well understood. Myocardial tissue of our patient obtained during myectomy at the age of 23 years was analyzed in detail by histochemistry, immunofluorescence staining, electron microscopy and western blot analysis. Cardiac histology showed a pathology typical for myofibrillar myopathy with myofibril disarray and abnormal protein aggregates containing BAG3, desmin, HSPB5 and filamin C. Analysis of sarcomeric and intercalated disc proteins showed focally reduced expression of the gap junction protein connexin43 and Xin-positive sarcomeric lesions in the cardiomyocytes of our patient. In addition, autophagy pathways were altered with upregulation of LC3-II, WIPI1 and HSPB5, 6, 7 and 8. We conclude that the p.Ala2430Val mutation in FLNC most probably is associated with HCM characterized by abnormal intercalated discs, disarray of myofibrils and aggregates containing Z-disc proteins similar to myofibrillar myopathy, which supports the pathological effect of the mutation.

Abstract
BACKGROUND Dilated cardiomyopathy (DCM) is a leading cause of death in children with heart failure. The outcome of pediatric heart failure treatment is inconsistent, and large cohort studies are lacking. Progress may be achieved through personalized therapy that takes age- and disease-related pathophysiology, pathology, and molecular fingerprints into account. We present single nuclei RNA sequencing from pediatric patients with DCM as the next step in identifying cellular signatures. METHODS We performed single nuclei RNA sequencing with heart tissues from 6 children with DCM with an age of 0.5, 0.75, 5, 6, 12, and 13 years. Unsupervised clustering of 18 211 nuclei led to the identification of 14 distinct clusters with 6 major cell types. RESULTS The number of nuclei in fibroblast clusters increased with age in patients with DCM, a finding that was confirmed by histological analysis and was consistent with an age-related increase in cardiac fibrosis quantified by cardiac magnetic resonance imaging. Fibroblasts of patients with DCM >6 years of age showed a profoundly altered gene expression pattern with enrichment of genes encoding fibrillary collagens, modulation of proteoglycans, switch in thrombospondin isoforms, and signatures of fibroblast activation. In addition, a population of cardiomyocytes with a high proregenerative profile was identified in infant patients with DCM but was absent in children >6 years of age. This cluster showed high expression of cell cycle activators such as cyclin D family members, increased glycolytic metabolism and antioxidative genes, and alterations in ß-adrenergic signaling genes. CONCLUSIONS Novel insights into the cellular transcriptomes of hearts from pediatric patients with DCM provide remarkable age-dependent changes in the expression patterns of fibroblast and cardiomyocyte genes with less fibrotic but enriched proregenerative signatures in infants.

Abstract
In times of donor organ shortage, organs with extended allocation criteria, for example, valve pathologies, have to be taken into consideration for transplantation. The donor pool can be extended to hearts with mitral valve insufficiency. Mitral valve repair can rapidly be performed in the donor heart on the back table with excellent results.

Abstract
Interest in the concept of caring and the ethics of caring has grown as technology and depersonalization of health care delivery have increased. Major concepts of the ethics of caring are reviewed, with special focus on relating caring and virtue ethics. Assuming that caring is a virtue, it is concluded that ethically virtuous nurses must possess the caring attributes and demonstrate caring actions.

150 knees were re-examined after operative therapy because of chondromalacia patellae. We found good and very good results in 52.7%. The results after lateral release were statistically significant better than the results after after the other methods. Because of 82% good results the lateral release operation can be recommended.

Abstract
150 knees were re-examined and rated with a modified Bentley-score to estimate the results of the conservative treatment of chondromalacia patellae. 25 several methods in 74 various combinations were used in the treatment. Only injections of Arteparon, short waves and iontophoresis with histamine were applied as single treatment in some knees. None of these methods, applied as single or in combination with other ones, gave results, which were statistically significant better than those of the other ones. In the conservative treatment of chondromalacia patellae the polypragmasy should be stopped and arthro-muscular rehabilitation should be regarded as the principle task.
