In-Hospital Outcomes Following Left Atrial Appendage Closure, Shubrandu S. Sanjoy Jul 2020

In-Hospital Outcomes Following Left Atrial Appendage Closure, Shubrandu S. Sanjoy

Electronic Thesis and Dissertation Repository

Left atrial appendage closure (LAAC) is a non-pharmacologic approach for stroke prevention in patients with atrial fibrillation. The impact of comorbidity burden on adverse outcomes following LAAC is very important for clinical decision making. Cohort-based observational study was conducted to evaluate the association of comorbidity burden with in-hospital complications. Of 3294 participants (mean age was 75.7±8.2 years), 60% were male and 86% whites. The majority of participants undergoing LAAC presented with a significant number of comorbid conditions. The occurrence of in-hospital major adverse events (MAE) was 4.6%. Women and patients exhibiting higher Charlson Comorbidity Index (adjusted odds ratio [aOR]: 1.14, …


Evaluating White Matter Changes And Executive Function In Rat Models Of Mediodorsal Thalamic Stroke And Neuroinflammation, Jessica Garabon Jun 2018

Evaluating White Matter Changes And Executive Function In Rat Models Of Mediodorsal Thalamic Stroke And Neuroinflammation, Jessica Garabon

Electronic Thesis and Dissertation Repository

Recent literature has supported a relationship between vascular disease and its role in the progression of cognitive impairment. Previous studies have demonstrated that white matter inflammation (WMI) in the brain is a common pathological outcome following stroke. Moreover, WMI has been shown to be the strongest predictor of cognitive decline following stroke. Finally, previous work in our lab has demonstrated, using a rodent model of striatal stroke, that WMI is correlated with post-stroke cognitive impairment. The current study aimed to further investigate the role of WMI in post-stroke cognitive impairment by utilizing a mediodorsal thalamic (MD) stroke model in the …


Causes Of Post Stroke Falls Along The Care Continuum: Implications For Improving Patient Safety, Mona Madady Jun 2013

Causes Of Post Stroke Falls Along The Care Continuum: Implications For Improving Patient Safety, Mona Madady

Electronic Thesis and Dissertation Repository

In Western countries stroke is responsible for 10-12% of all deaths. In 2000, strokes cost $3.6 billion for the Canadian healthcare system and lost productivity due to premature death and long-term disability. Falls are a frequent occurrence at all stages of post-stroke recovery and can have significant negative impacts. While information about the incidence and risk factors of falling among stroke survivors is available, considerably less is known about the specific factors contributing to falls and the circumstances surrounding these adverse events. The purpose of this project was to identify similarities between systemic factors of falls in stroke survivors across …


An Investigation Into The Combined Effects Of Β-Amyloid Toxicity And Cerebral Ischemia On The Pathological Expression Of Gangliosides., Jeffrey D. Hepburn Oct 2012

An Investigation Into The Combined Effects Of Β-Amyloid Toxicity And Cerebral Ischemia On The Pathological Expression Of Gangliosides., Jeffrey D. Hepburn

Electronic Thesis and Dissertation Repository

Identifying mechanisms underlying the synergistic pathological interaction between stroke and Alzheimer’s disease (AD) can effectively guide future therapeutic strategies for these highly co-morbid conditions. Aberrant ganglioside expression marked by the pathological accumulation of ganglioside GM3 is common to stroke and AD, yet it is unclear whether GM3 is synergistically enhanced in a comorbid model, or if GM3 is a viable therapeutic target. Adult male Wistar rats received a unilateral ischemic striatal infarct via endothelin-1 (ET-1) injection alone or in combination with bilateral intracerebroventricular injection of the β-Amyloid 25-35 peptide (Aβ) to induce generalized Aβ toxicity (Aβ/ET-1). Animals were sacrificed after …


Three-Dimensional Ultrasound Measurements Of Carotid Atherosclerosis In Vulnerable Patient Populations, Daniel N. Buchanan Apr 2012

Three-Dimensional Ultrasound Measurements Of Carotid Atherosclerosis In Vulnerable Patient Populations, Daniel N. Buchanan

Electronic Thesis and Dissertation Repository

Atherosclerosis is a progressive disease that leads to plaque development and is associated with cardiovascular events such as myocardial infarction and stroke. Several biomarkers have been established as surrogates of plaque development yet none can provide direct, noninvasive, rapid measurements of atherosclerotic disease. Three-dimensional Ultrasound (3DUS) image acquisition is safe, inexpensive and fast, however 3DUS image measurements are limited due to time consuming manual image analyses. In addition, the true clinical meaning of 3DUS carotid imaging measurements has not yet been established. A semi-automated approach for the estimation of 3DUS Total Plaque Volume (TPV) was developed with similar variability and …
