Author Interviews, HIV, NEJM / 20.03.2020

MedicalResearch.com Interview with: Susan Swindells MBBS Professor, Infectious Diseases Department of Internal Medicine University of Nebraska Medical Center Omaha, NE MedicalResearch.com: What is the background for this study? Response: The background for this study is the development of long-acting injectable formulations of two antiretroviral agents: cabotegravir and rilpivirine.  These were previously tested in a Phase 2 study, and the current study (called ATLAS) reports findings from Phase 3 in which HIV-infected patients on antiretroviral therapy were switched to monthly injections. The partner study, (FLAIR), is published in the same addition of the journal, and reports results from patients that were new to antiretroviral therapy, and took oral medications as a lead-in to achieve viral suppression before switching to similar monthly injections.  Both studies included randomization to continuing oral antiretroviral therapy.

MedicalResearch.com Interview with: Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center  MedicalResearch.com: What is the background for this study? Response: E-cigarette use increased significantly from 2017 to 2019 among U.S. adolescents, and marijuana and other substances besides can be used in e-cigarettes. Meanwhile, restrictions on marijuana use have been relaxing and social acceptability of marijuana use is shifting among youth. This study analyzed 38,061 middle and high school students from the 2017 and 2018 National Youth Tobacco Survey.  (more…)
Author Interviews, Cannabis, JAMA / 05.10.2019

MedicalResearch.com Interview with: Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center  MedicalResearch.com: What is the background for this study? Response: Although marijuana is still classified as a Schedule I drug at the Federal level, as of June 2019, 33 states and the District of Columbia have legalized one or more forms of marijuana; 11 states and the District of Columbia have approved both medical and recreational uses. Public opinion on marijuana has changed dramatically over the last two decades and support for legalization has doubled since 2010. However, very little is known about the prevalence and patterns of marijuana use among adults with medical conditions. This study analyzed the 2016 and 2017 Behavioral Risk Factor Surveillance System data to report the prevalence and patterns of marijuana use among adults with self-reported medical conditions.  (more…)

MedicalResearch.com Interview with: Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center Omaha MedicalResearch.com: What is the background for this study? Response: Previous studies have reported a surge in e-cigarette use among youth during the 2017 - 2018. For instance, the prevalence of current (past 30-day) e-cigarette use increased by 77.8% (from 11.7% to 20.8%) among high school students and by 48.5% (from 3.3% to 4.9%) among middle school students. As a result, the Food and Drug Administration (FDA) warns that youth e-cigarette use is reaching an epidemic proportion in September 2018. Whether e-cigarette use prevalence also increased among young adults (aged 18-24 years), a population with high e-cigarette use rates and vulnerability to nicotine dependence, is unknown. (more…)
Author Interviews, Infections, NEJM / 13.03.2019

MedicalResearch.com Interview with: Susan Swindells MBBS Professor and Medical Director, HIV Clinic Department of Internal Medicine University of Nebraska Medical Center Omaha, NE MedicalResearch.com: What is the background for this study? What are the main findings?  Response: More than one quarter of the world’s population is infected with tuberculosis (TB), and there is effective treatment for this but only a small fraction of those eligible actually receive it.   TB is the leading cause of death for people with HIV infection, globally.  One of the major problems with currently available treatments for TB infection is that they take too long, and people just stop taking them after a while.  We identified an ultra-short course of treatment (only one month) and tested it against the conventional 6-month course of treatment. Our main findings were that the new short course was just as effective as the standard 6 month course, more patients taking the short course completed their treatment, and had less adverse effects.  (more…)
Author Interviews, JAMA, Pediatrics, Smoking, Tobacco, Tobacco Research / 07.01.2019

MedicalResearch.com Interview with: Dr. Hongying Dai, PhD Associate Professor at the College of Public Health University of Nebraska Medical Center. MedicalResearch.com: What is the background for this study? Response: The 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA) banned cigarettes with characterizing flavors (e.g., candy, fruit, clove) except menthol. However, there are no restrictions on the marketing and sales of flavored non-cigarette tobacco products. This has led to a proliferation of flavored tobacco products in the marketplace. Flavoring has become one of the leading reasons for current tobacco use among youth. It is reported that 81% of e-cigarette users, 79% of hookah users, 74% of cigar users, 69% of smokeless tobacco users, and 67% of snus users attributed the availability of appealing flavors for their tobacco use in 2013–2014 among teenagers aged 12 to 17 years. In November 2018, the FDA proposed new restrictions on flavored tobacco products. (more…)
