Using these risk factors, physicians may be able to better identify children who will or will not benefit from life-saving transplantation surgery; the current criteria for receiving a transplant sometimes miss children who may benefit.
If the findings of the report are successfully used nationwide, the indications for heart transplantation may be broadened giving more children access to this life-prolonging therapy.
“Competing risks for death and cardiac transplantation in children with dilated cardiomyopathy: results from the Pediatric Cardiomyopathy Registry,” was published online today in Circulation, the journal of the American Heart Association.
Risk factors identified for either death, transplantation, or both include presence of congestive heart failure, echocardiographic evidence of more severe disease, increased age, dilation of the left ventricle, and height. Short stature increased the risk of death but not transplantation. Researchers also found that the causes of dilated cardiomyopathy strongly affected which risk factors were predictive of death and/or transplantation. This suggests that establishing the cause of disease as soon as possible is critically important.
This population-based study used data from the Pediatric Cardiomyopathy Registry (PCMR). From 1990 to 2007, the PCMR, led by the University of Miami Leonard M. Miller School of Medicine, enrolled 1,731 children (18 years of age or younger) diagnosed with pediatric dilated cardiomyopathy, the most common heart muscle disease. Dilated cardiomyopathy can lead to heart valve problems, arrhythmias (irregular heartbeats), blood clots in the heart, and even heart failure.
For 57 percent of children who suffer from cardiomyopathy, the cause of the disease is unknown. The nationwide registry was established to collect and organize data on the condition, which will help determine the causes of the disease and lead to new and better treatments.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
