'Stroke Belt' Deaths Tied to Non-Traditional Risk FactorsJanuary 12, 2009• Stroke risks go beyond geographic and racial differences • Diabetes and hypertension rates higher for this region BIRMINGHAM, Ala. - Southerners die from stroke more than in any other U.S. region, but exactly why that happens is unknown. A new report by researchers at the University of Alabama at Birmingham (UAB) and the University of Vermont underscores that geographic and racial differences are not the sole reasons behind the South's higher stroke death rate. The data is from UAB's Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, which has enrolled more than 30,200 U.S. participants. The study confirms a greater-than 40 percent higher stroke death rate in eight southeastern states known as the Stroke Belt - Alabama, Arkansas, Georgia, Louisiana, Mississippi, North and South Carolina and Tennessee. After factoring in age, race and sex-related factors, the predicted stroke risk was only slightly higher in Stoke Belt states compared to other regions (10.7 percent versus 10.1 percent), said George Howard, Dr.PH., professor of biostatistics in UAB's School of Public Health and a REGARDS principal. That risk was calculated using nine known risk factors common to stroke screening. SOMETHING ELSE HAPPENING "We found geographic and racial differences are useful in predicting stroke risk, but they only explain less than half the picture. Something else is happening," Howard said. "It could be exposure to allergens in the home, it could be micronutrients in drinking water or it could be other factors considered 'non-traditional' because they don't fall into the list of nine factors commonly used to predict stroke risk." The findings are reported in the Annals of Neurology. All minority groups, including Native Americans, Hispanics and African-Americans, face a significantly higher risk for stroke and death from stroke compared to whites, and research is focused on exactly why that is, said Mary Cushman, M.D., of the University of Vermont, the study's lead author. Continued analysis of REGARDS data and follow-up study will determine other stroke risk factors and their significance. One detail that emerged in the Annals of Neurology study is that the prevalence of diabetes and hypertension was up to five percentage points higher in the Southeast. That means interventions to reduce geographic disparities in diabetes and hypertension - including boosting diabetes screening rates and follow-up care - could also reduce geographic disparities in stroke death, Howard said. REGARDS already has spawned more than 50 accompanying research reports. The study is a research partnership that includes UAB's Departments of Epidemiology, Biostatistics and Preventive Medicine, UAB's Center for Aging and the Center for the Study of Community Health, the University of Vermont in Burlington, the University of Arkansas for Medical Sciences in Little Rock, the University of Cincinnati, Indiana University in Indianapolis, the Alabama Neurological Institute in Birmingham, the Medical University of South Carolina in Charleston and Wake Forest University School of Medicine in Winston-Salem, N.C.

New discovery about the formation of new brain cells The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. Multiple health concerns surface as winter, vitamin D deficiences arrive A string of recent discoveries about the multiple health benefits of vitamin D has renewed interest in this multi-purpose nutrient, increased awareness of the huge numbers of people who are deficient in it, spurred research and even led to an appreciation of it as "nature's antibiotic." New understanding about mechanism for cell death after stroke leads to possible therapy Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. Surgery not linked to memory problems in older patients For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study from researchers at Washington University School of Medicine in St. Louis questions those assumptions. Pushing the brain to find new pathways Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities.
