A main challenge for targeting chronic kidney disease (CKD) is the heterogeneity of its causes, co-morbidities and outcomes. Patients under nephrological care represent an important reference population, but knowledge about their characteristics limited. We enrolled 5217 carefully phenotyped patients with moderate CKD [estimated glomerular filtration rate (eGFR) 30–60 mL/min per 1.73 m2 or overt proteinuria at higher eGFR] routine nephrologists into German Chronic Kidney Disease (GCKD)...

Erythropoietin (EPO) mobilises endothelial progenitor cells and promotes neovascularisation in heart failure. The present authors studied the effects of EPO on pulmonary vascular cardiac remodelling a model for flow-associated arterial hypertension (PAH). PAH was induced adult male Wistar rats by injection monocrotaline combined with an abdominal aortocaval shunt 1 week later (PAH or experimental group). Immediately afterwards, were randomised into those who received treatment (PAH+EPO...

Primary chronic kidney disease is associated with high cardiovascular risk. However, the exact mechanisms behind this cardiorenal interaction remain unclear. We investigated between heart and kidneys in novel animal model for interaction. Normal Wistar rats Munich Fromter rats, spontaneously developing renal dysfunction, were subjected to experimental myocardial infarction induce cardiac dysfunction (CD) combined (CRD), respectively (N = 5-10). Twelve weeks later, cardiac- parameters...

<title>Abstract</title> Background The demand for managing congenital heart disease (CHD) exceeds the available resources in low- and middle-income countries (LMICs). This has resulted a growing population of children with CHD, only few receiving surgical interventions, while many more are waiting intervention. Health-related quality life (HRQOL) its impact on pediatric CHD these settings have been largely overlooked, limited research conducted. Therefore, this study aimed to explore HRQOL...
