Exploring The Efficacy Of Mir-33 Antagonism In Promoting Regression Of Intracranial Atherosclerosis In A Nonhuman Primate Model, Peter Hecker

Theses and Dissertations--Pharmacology and Nutritional Sciences

Atherosclerosis, characterized by lipid accumulation and arterial inflammation, is a major contributor to global morbidity and mortality. Despite significant progress in understanding atherosclerosis in extracranial arteries, the study of intracranial atherosclerosis (ICAS) has been relatively neglected, despite its crucial role in stroke and vascular cognitive impairment. Challenges related to ICAS, including its location within the cranium and limited availability of suitable animal models, have hindered research progress in this area. Although nonhuman primates (NHPs) are commonly used for studying extracranial atherosclerosis, a comprehensive understanding of ICAS pathophysiology in these animals is lacking. By subjecting NHPs to a high-fat/cholesterol diet, we …

Case Report: Repeated Use Of Tetrahydrocannabinol Associated With Severe Cerebral Vasoconstriction, Pooja Patel, Ryna Then, Dena Little

Rowan-Virtua Research Day

Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a rare neurological syndrome. The classic presentation consists of recurrent, severe, ”thunderclap” headaches with neuroimaging findings consistent with segmental vasoconstriction of cerebral arteries. Sympathomimetics including cannabinoids have been found to be triggers in many cases of RCVS. Complications include subarachnoid hemorrhage, intracerebral hemorrhage, cerebral edema and ischemic infarction.

This case highlights the potential devastating and irreversible effects of RCVS precipitated by exposure to a sympathomimetic agent. The case emphasizes the importance of patient counseling regarding abstinence from agents that may provoke RCVS.

Retrograde Thromboembolism From The Proximal Descending Thoracic Aorta Leading To Recurrent Acute Cerebrovascular Events, Mark Staroelsky, Akash Patel, Gregory Holland, Nishant Parikh, Peter Bulik

Rowan-Virtua Research Day

In the United States, approximately 800,000 individuals experience a stroke every year

Nearly 25% of strokes are recurrent

Cryptogenic strokes, or those with unknown causes after testing, make up a significant portion of ischemic strokes, as many as 32%

Retrograde thromboembolic events originating from the proximal descending thoracic aorta should be considered as a potential etiology in cryptogenic strokes

The appropriate management of embolic events from aortic atheroma needs further research

Here, we present a case of a 55-year-old male who had recurrent cryptogenic strokes whose origin was discovered to stem from retrograde embolic phenomena from atheroma located within the …
