The world experts on aging research at the University of Texas Medical Branch at Galveston have again received an international designation acknowledging their niche in an area that grows more complex every day as the elderly population explodes worldwide. UTMB's Sealy Center on Aging has been redesignated by the World Health Organization as a World Health Organization/Pan American Health Organization (WHO/PAHO) Collaborating Center in Aging and Health. WHO/PAHO Collaborating Centers assist the global organization to investigate public health issues from many angles, ranging from basic science and animal studies to clinical trials, public policy, training and dissemination. UTMB is one of only three institutions in the United States to receive this designation. UTMB's Sealy Center on Aging plays a role as an information resource and a center for innovative, multidisciplinary research on a tremendous range of different aging issues, from stroke and dementia to falls, hospital readmissions, exercise, nutrition, palliative care decision-making, physical therapy, chronic disease, poverty, pensions, and a wide array of other clinical and health-policy related issues.
