Author Interviews, Biomarkers, JAMA, Tobacco Research / 09.11.2022

MedicalResearch.com Interview with: Dr. Hongying Daisy Dai, PhD Professor and Associate Dean of Research The College of Public Health University of Nebraska Medical Center. MedicalResearch.com: What is the background for this study? Response: Tobacco use landscape has been changing in the United States with fewer combustible cigarette smokers and more e-cigarette and other emerging tobacco users. Nicotine concentration level is a key product characteristic of modern e-cigarette products and high-nicotine vaping devices have recently become available. This study seeks to examine whether biomarkers of exposure to tobacco-related toxicants have changed since 2013 among adult nicotine e-cigarette users, non-nicotine e-cigarette users, and cigarette smokers.

What are the main findings?  Response: Although the health effects of e-cigarettes remains unclear, e-cigarettes have been marketed as an approach for smoking cessation. Previous studies have reported an increase in e-cigarette use in US people since 2010. The current study showed that from 2014 to 2016, there was an increase in ever use of e-cigarettes but decline in current use of e-cigarettes.  (more…)
Author Interviews, Heart Disease, JAMA, Tobacco Research, UCLA / 01.02.2017

MedicalResearch.com Interview with: Holly R. Middlekauff, MD Professor UCLA Division of Cardiology David Geffen School of Medicine UCLA MedicalResearch.com: What is the background for this study? What are the main findings? Response: E-cigarettes are the fastest rising tobacco product in the US today, but almost nothing is known about their cardiovascular effects. Rather than wait decades for epidemiological data in e-cigarette users to become available, we reasoned that investigations into the known mechanisms by which tobacco cigarettes increase heart disease would provide insights into the health risks of e-cigarettes. We focused on 2 critical mechanisms: 1) cardiac adrenaline activity, and 2) oxidative stress, measured in chronic e-cigarrete users compared to matched, healthy controls. The major findings were that, compared to healthy controls, e-cig users had increased cardiac adrenaline activity (measured by a technique called "heart rate variability"). Furthermore, compared to healthy controls, the e-cig users had increased susceptibility to oxidative stress. (more…)
