Brain injured athletes may benefit from hypothermia researchNovember 16, 2009NFL players and other athletes who suffer serious or multiple concussions may benefit from ground-breaking research being conducted by scientists at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center. The scientists are developing a surgical technique that involves hypothermia in specific regions of the brain. Therapeutic hypothermia is a medical treatment that lowers a patient's temperature in order to help reduce the risk of injury to tissue. The endovascular intra-arterial cooling method being studied at Barrow rapidly preserves the injured portion of the brain and minimizes damage. Results from the studies, which are being led by Barrow's director of Neurosurgery Research Mark Preul, MD, have been published in academic journals such as Neurological Research. "The ability to cool a specific region of the brain allows us to protect the tissue and avoid risk of damage to other organs that can occur with whole body hypothermia," says Dr. Preul. "This work is targeted currently at severe injuries to the brain like massive strokes or trauma, but it also means we could be able to offer a less invasive and specific approach to saving brain tissue. We're working to develop ways to be more proactive about treating brain injuries like sports concussions that may have been under-treated in the past." The filter-cooling unit technology works similar to renal dialysis, removing a volume of blood and replacing it with a cooled crystalloid solution through a catheter in the carotid artery. The rest of the brain and body maintain a normal temperature. The cooling process quickly lowers the metabolic rate of the tissue, protecting it from stress and further damage. Results could be particularly welcome news for the NFL, which has been under fire from a House Judiciary Committee recently. The league also has been scrutinized in news reports for its medical treatment of former players who show signs of dementia and other types of mental decline. "We're encouraged by our results in the lab, and believe it could translate into faster clinical response and improved outcomes for patients with brain injuries, including athletes, military personnel and trauma patients," says Dr. Preul.

By inducing the release of nitric oxide (NO) gas in mice with septic shock, researchers Anje Cauwels and Peter Brouckaert discovered that the animal's organs showed much less damage, while their chances of survival increased significantly. Chances of surviving cardiac arrest at home or work unchanged in 30 years The chance of surviving an out-of-hospital cardiac arrest has not improved since the 1950s, according to a report by the University of Michigan Health System. Scripps research scientists find new link between insulin and core body temperature A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin-a hormone long associated with metabolism and metabolic disorders such as diabetes-and core body temperature. Global death toll: 1 million premature babies every year More than one million infants die each year because they are born too early, according to the just released White Paper, The Global and Regional Toll of Preterm Birth. Cooling treatment after cardiac arrest is cost-effective, Penn study shows A brain-preserving cooling treatment called therapeutic hypothermia is a cost-effective way to improve outcomes after out-of-hospital cardiac arrest, which claims the lives of more than 300,000 people each year in the United States and leaves thousands of others neurologically devastated. Coronary angiography may improve outcomes for cardiac arrest patients People who suffer cardiac arrests and then receive coronary angiography are twice as likely to survive without significant brain damage compared with those who don't have the procedure, according to a study by University of Pittsburgh School of Medicine researchers. Therapeutic hypothermia is promising strategy to minimize tissue damage Recognition of the benefits of cooling strategies to protect the brain and spinal cord after traumatic injury has led to a wealth of cutting edge research, prime examples of which are featured in a special hypothermia issue of Journal of Neurotrauma. Anesthesia or hypothermia: Warning for Alzheimer's patients Everyone knows that its important to keep a cool head, but a new study published online in The FASEB Journal shows that for Alzheimer's patients, a cool head may make the disease worse. Anesthesia is found to induce hyperphosphorylation of tau at sites related to Alzheimer's disease Scientists from The New York State Office of Mental Retardation and Developmental Disabilities' (OMRDD) New York State Institute for Basic Research in Developmental Disabilities (IBR) report today in the March 2009 issue of the Journal of Alzheimer's Disease that anesthesia induces phosphorylation of tau. Penn study: Chances of surviving cardiac arrest depend on where patients are treated Efforts to fight the toll of cardiac arrest have typically focused on pre-hospital factors -- bystander CPR education and improvement, public defibrillation programs, and quicker EMS response. But new research from the University of Pennsylvania School of Medicine reveals that the hospital where patients are cared for after being resuscitated plays a key role in their chances of survival following these incidents, which takes the lives of more than 300,000 Americans each year.
