PHOENIX, Ariz. Dec. 4, 2013 In an effort to lower medical costs, identify patients at risk for injury, and speed patient recovery, scientists will attempt to identify a molecular signal that indicates severity of brain-injury during a $4 million, five-year federal grant to Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, Phoenix Children's Hospital and the Translational Genomics Research Institute (TGen).
The molecular profile comprised of RNA, the body's relay messenger between DNA and protein could help identify which patients are most at risk for vasospasm after hemorrhagic stroke. Hemorrhagic stroke can occur as:
By identifying this RNA molecular marker, a new standard of individualized care could be established, enabling medical teams to respond more rapidly to quickly changing health conditions, and allowing earlier intervention to prevent a secondary injury from occurring.
"We hope this study will lead to less injury, less testing and cost, and shorter stays in the hospital," said Dr. Yashar Kalani, M.D. and Ph.D., a resident physician in Neurological Surgery and assistant professor at the Barrow Neurological Institute and one of the study's principal investigators. Additional investigators at Barrow include Drs. Robert Spetzler, Peter Nakaji, Felipe Albuquerque and Cameron McDougall.
Vasospasms are characterized by bleeding in the brain that causes irritation and nearby blood vessels to spasm and narrow. This decreases blood flow to the brain, which can result in damage or even death to parts of the brain.
Only about half of patients with brain-aneurysm ruptures survive, and those who do survive often are severely disabled for life. In
