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.
