    Psychiatric Symptoms as a Predictor of Outcome in Patients with Post-Concussive Syndrome

    RESEARCH

    August 2015 Faster Start of IV tPA Does Not Decrease the Need for Endovascular Thrombectomy in Acute Ischemic Stroke

    In a prospectively maintained registry, I identified patients receiving IV tPA at 2 academic medical centers from March 2005 – May 2015. For this analysis I used the inclusion criteria of a target large artery occlusion seen on CTA or MRA before (or early during) infusion of IV tPA, and the performance of follow-up vessel imaging within 6h of IV tPA start, using CT, MR or catheter angiogram. Degree of thrombus lysis achieved by IV tPA was rated using the arterial occlusive lesion (AOL) Scale.The goal of the study was to determine if faster times to the administration of tPA after symptom onset would obviate the need for endovascular therapy.

    April 2014 Psychiatric Symptoms as a Predictor of Outcome in Patients with Post-Concussive Syndrome, Rush University Medical Center, Chicago, IL

    I performed a retrospective chart review of patients with the diagnosis of concussion or post-concussive syndrome that were seen at our institution over a 15 month period. Patients 16-75 years old who had suffered a concussion within 4 months prior to their clinic visit were included. Patients were excluded if they had a previous diagnosis of a psychiatric illness or suffered an intracranial bleed or skull/facial fracture while sustaining their concussion. Patients who exhibited the psychiatric symptoms of irritability, depression, anxiety, or changes in mood within 1 month after their concussion were compared to those who did not. The goal of the study was to determine if psychiatric symptoms experienced in the acute or subacute phase would portend a worse prognosis and longer recovery.

    October 2013 Utility of PFA Testing after Stent-Coil Aneurysm Repair

    Rush University Medical Center, Chicago, IL

    I retrospectively reviewed the last 100 stent placements done by two of our neuro-interventional attendings at Rush University using our electronic medical record. One attending performs PFA testing on all of his patients and makes adjustments to anti-platelet regimens accordingly and the other never performs PFA testing. I then retrospectively compared outcomes amongst the patients who received PFA testing versus those who didn’t. More specifically, I looked at the rate of thromboembolic complications and the rate of mild, moderate to severe hemorrhage in both populations. Ultimately I hoped to prove or disprove a need for PFA testing in patients with stent-coil treatment of their intracranial aneurysms.

    September 2012 Biomarkers for Cerebral Aneurysm Formation

    Rush University Medical Center, Chicago, IL

    I first reviewed the pathophysiology of cerebral aneurysm formation and the

    current role of biomarkers in the literature for tracking aneurysm development.

    We then postulated that elastase, lipoprotein A, MMP (gelatinase), homocysteine

    and plasmin correlated with aneurysm rupture. After receiving funding for lab work, we plan to enroll patients who have acutely undergone aneurysm rupture and compare their biomarker values to the serum values 6-months post coiling. We plan to compare this to controls and those with non-ruptured, unsecured

    aneurysms to hopefully find a range of values for each biomarker that could predict pending aneurysm rupture.

    August 2004 Brain Perfusion Characteristics of Cerebral Catheters

    UVA Mechanical Engineering Dept, Charlottesville, VA

    As part of my capstone engineering project, I tested the perfusion characteristics of various catheters upon infusion into cerebral tissue gels. Agarose gels were prepared weekly that had been shown, based on previous studies, to accurately simulate the properties of brain tissue. Different types of catheters were supplied to us by local biomedical companies and the perfusion characteristics of each catheter was tested by infusion into the model gels. The ultimate goal was to find an ideal catheter for chemotherapy infusion into brain tissue so that chemotherapy could be accurately targeted to the site of interest without harming healthy, normal tissue. I presented my findings in an undergraduate thesis.

    November 2003 Epidemiological Studies in Breast Cancer

    Breast Cancer Research Center, UVA Hospital, Charlottesville, VA

    Spent 10-15 hours a week working at the Breast Cancer center performing database entry of patient files into Microsoft Access. Each patient’s epidemiological data was entered and trends in those with breast cancer were identified. These trends were statistically analyzed with the goal of identifying risk factors and predictors of breast cancer so as to prevent its future occurrence.
