Clinical Research Focus:
My areas of clinical research focus are in cerebrovascular disease, specifically:
1) Antiphospholipid antibodies (aPL) and cerebrovascular disease.
I have been investigating the role of various aPL in predicting stroke risk (initial and recurrent), having developed the Antiphospholipid Antibodies and Stroke Study Group (APASS). Currently, I am investigating the role of persistent positivity of several aPL (specifically antibodies to β2-glycoprotein-I, antiphosphatidylserine antibodies, and anticardiolipin antibodies) as a portfolio in predicting recurrent stroke and thrombo-occlusive events. A recently started project, funded by NHLBI, is investigating the role of various aPL in predicting pathologically proven cerebral infarction in a large cohort of aging individuals (at RUSH University), as well as looking at mechanism of infarction related to annexin resistence and relationship of aPL to intracranial large vessel atherosclerosis.
2) Telemedicine for stroke (“Telestroke”).
a) Developing a protocol to study the use of hand-held devices (iPad, iPhone) for use in obtaining and interpreting acute head CT scans in acute stroke patients – determining the validity and reliability compared to the gold standard neuroradiology read on a desk top/work station. Long term goal is to develop the ability to conduct clinical stroke treatment trials using telemedicine at community/rural hospital sites.
b) Developing and validating quality indicators for acute stroke care via telemedicine
3) Thrombolytic therapy for acute ischemic stroke
a) Studying the prevalence, magnitude, and prognostic significance of rapidly improving stroke symptoms/signs (RISS) in acute stroke patients. Long term goal is to determine optimal treatment decisions for patients with rapidly improving symptoms/signs based on magnitude of RISS
4) Mobile Applications for Stroke (MAPPS)
a) Developing mobile apps for stroke survivors and their caregivers through a PCORI-funded grant. Phase 2 will involve testing the apps and determing their utlity
5) Post-stroke fatigue (PSF)
a) Determining factors (clinical, neuroimaging) that predict occurrence of PSF.
6) Primary Stroke Prevention in Women (PSPW)
a) Determining knowledge practice patterns of PSPW in all 3 primary care providers specialties (Family Medicine, Internal Medicine, and OBGYN)
b) Determine women’s knowledge and preferences for PSP
