Antiseizure Medications And Their Differing Effects On Cardiovascular Risk, Aleena Abbasi, Bassil Abbasi, Scott Mintzer, Carla Lopinto-Khoury

Department of Neurology Faculty Papers

This review discusses the differing effects of enzyme-inducing and non-inducing antiseizure medications on cardiovascular risk and their implications for the management strategies of epilepsy patients. Traditional risk markers, including low density lipoprotein, high density lipoprotein and triglycerides, can be altered by both enzyme induction and inhibition. Other markers of vascular risk, including c-reactive protein, non-high-density lipoprotein and homocysteine, are affected by antiseizure medications, although adults and children may have different responses. The overall atherosclerotic risk picture is more complex due to indirect effects such as neuroendocrine function and the metabolic syndrome. Large scale data shows an evolving understanding of cardiovascular …

Interdisciplinary Research Among Tourism, Public Health, And Global Health: A Promising Stream Focusing On Populations With Suboptimal Health Status, Jun Wen, Fangli Hu, Danni Zheng, Haifeng Hou, Wei Wang

Research outputs 2022 to 2026

Research suggests that approximately 75% of the world's population suffers from suboptimal health status, meaning these individuals often feel unwell but have no clearly diagnosable conditions. Suboptimal health status, originating from traditional Chinese medicine, signifies an intermediate state between health and disease. Tourism has been deemed beneficial for personal health and general well-being. More recently, it has been proposed as a non-pharmacological intervention for individuals with dementia, given its potential contributions to health promotion and disease prevention/treatment. Yet, the tourism literature has paid scarce attention to populations with suboptimal health status, even as an aging society becomes inevitable. This paper …
