To determine average glucose levels in the blood over a two to three month period, doctors measure glycosylated hemoglobin (the oxygen-carrying protein in the blood that is bound to the sugar glucose). In general, higher levels have been associated with increased risk of heart disease, said Dr. David Aguilar, assistant professor of medicine – cardiology at BCM (http://www.bcm.edu/news/broadcastcenter/expert.cfm?expertid=150).
"Most doctors try to keep glucose levels of those with diabetes as low as they can to lower the risk of complications such as eye problems, kidney disease or the development of heart disease," said Aguilar, senior author of the study. "However, we found that in diabetic patients with heart failure, glucose levels slightly higher than what are normally recommended had the lowest risk of death."
Researchers at BCM and the Michael E. DeBakey Veterans Affairs Medical Center (http://www.houston.va.gov/) in Houston identified 5,815 veterans with heart failure and diabetes who were receiving treatment at VA medical centers across the nation. They followed the patients for two years, dividing them into five categories based on their glycosylated hemoglobin levels.
Most medical professionals recommend levels at 7 and below as the target for optimal health for diabetic patients. However, the results of the study of diabetic patients with heart failure showed that those with levels 7.1 to 7.8 had the lowest rate of death. Those patients at both ends of the spectrum had the higher death risks.
"This doesn't mean that diabetic patients with heart failure should change their target goal for glucose levels," Aguilar said. "The results could simply be telling us that the glycosylated hemoglobin levels are a marker for other risks that are contributing to increased risk of death, but not necessarily the cause of the problem."
Aguilar said the correlation needs to be further investigated to confirm the findings and see what other factors could be contributing to the mortality rate.
The research is supported by a V.A. Health Services Research and Development Service grants and a National Institutes of Health Mentored Career Development Award.
Other researchers who took part in this study include, Drs. Biykem Bozkurt, Kumudha Ramasubbu and Anita Deswal, all from the Winters Center for Heart Failure Research and Section of Cardiology, and the Department of Medicine at BCM. Deswal is also at the Houston Center for Quality of Care and Utilization Studies at the Michael E. DeBakey V. A. Medical Center in Houston.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
