Research Summary

Enrique Leira MD MS specializes in Cerebrovascular Diseases and Epidemiology. His research focus is acute stroke management, including evidence-based strategies to improve and accelerate stroke treatment in rural areas. There is an unacceptable disparity in acute stroke practices between urban tertiary centers and those 25% patients living in rural areas. The gap will be further increased as rural patients continue to be excluded from time-dependent stroke trials due to distance/time from research centers. His research interests include novel strategies to enable participation of patients living in rural areas in acute trials testing stroke therapies, such as randomization before arrival to the University while they are being transported in a helicopter ambulance. Dr. Leira is also interested in designing novel forms of integrated physiological monitoring for stroke patients in order to modernize the current practice of performing gross "neurochecks" by nurses. The goal is to improve the beneficial effect of dedicated stroke units by detecting neurological deterioration in an objective, real time manner, without having to wake up the patient every few hours. He is a member of the Operator Performance laboratory in the College of Engineering. http://www.ccad.uiowa.edu/opl/. He also has an interest in aviation neurology, neurological emergencies in flight and developing real-time telecommunication solutions for the helicopter ambulances that transport stroke patients from small rural hospitals to large tertiary care centers.
