Author Interviews, Columbia, Heart Disease, Mediterranean Diet, Women's Heart Health / 13.03.2020

MedicalResearch.com Interview with: Dr. Riddhi Shah, PhD AHA SFRN Postdoctoral Research Fellow Division of Cardiology Columbia University Medical Center New York, New York MedicalResearch.com: What is the background for this study? Response: The Mediterranean Diet, characterized by higher intakes of plant foods including plant proteins, monounsaturated fat, fish, and lower consumption of animal products and saturated fat, has long been associated with reduced cardiovascular risk and greater longevity, but the molecular mechanisms underlying these associations have not been fully elucidated. We evaluated associations of an Alternate Mediterranean Diet Score, reflective of adherence to this diet pattern and adapted for US populations, and its components with markers of endothelial inflammation directly measured in endothelial cells harvested from women, including oxidative stress, nuclear factor kappa B (NFκB), and endothelial nitric oxide synthase (eNOS) gene expression.

Author Interviews, COVID -19 Coronavirus, CT Scanning, Global Health, Medical Imaging / 13.03.2020

MedicalResearch.com Interview with: Soheil Kooraki  MSR MS, MD on behalf of Dr. Ali Gholamrezanezhad MD and co-authors Department of Radiological Sciences, David Geffen School of Medicine, University of California at Los Angeles Los Angeles, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: COVID19 is a novel strain of the coronavirus family causing pneumonia. Two similar strains were discovered in 2003 and 2012 to cause the so-called SARS and MERS outbreaks, respectively. Radiologists need to be prepared for the escalating incidence of COVID-19. We reviewed the literature to extract the epidemiologic and imaging features of SARS and MERS in comparison with known imaging features of COVID-19 pneumonia to have a better understanding of the imaging features of the COVID19 pneumonia in acute and post-recovery stages.

Author Interviews, Lyme / 13.03.2020

MedicalResearch.com Interview with: Donal Bisanzio PhD DVM Senior Epidemiologist RTI International MedicalResearch.com: What is the background for this study? Response: The number of reported cases of Lyme disease has steadily increased since the year 2000. The Centers for Disease Control Prevention (CDC) estimates that nearly 30,000 cases are reported each year with close to 270,000 unreported cases. The high fraction of unreported cases is linked with the absence of specific disease symptoms, which can deter physicians from an initial diagnosis. Another critical factor causing underreporting is the low accuracy of methods used to test Lyme disease. These factors show us that some counties that are currently considered Lyme disease-free may only have this status due to underreporting. RTI International, in collaboration with Columbia University, built a model to show factors affecting the diffusion of case reporting in the north-eastern U.S. from 2000 to 2017 and identify which counties may be experiencing underreporting. The model used publicly available data published each year by the CDC on cases reported at the county-level merged with information on vector distribution and data obtained by satellite surveys. The model included 855 counties located in 31 states in the West North Central, East North Central, New England, Mid-Atlantic, and Southern regions of the U.S. The final product was a map showing the probability of counties of the north-eastern U.S. to report Lyme disease cases.  (more…)
Author Interviews, Cancer Research, JAMA / 13.03.2020

MedicalResearch.com Interview with: Alyson Haslam, PhD Nutritional Epidemiologist Center for Indigenous Health Research and Policy Oklahoma State University MedicalResearch.com: What is the background for this study? Response: Checkpoint inhibitor drugs for the treatment of cancers have received a lot of attention in recent years because of their ability to induce responses in certain tumors. To quantify the eligibility and response of these drugs in the US population, we published an article about a year ago (https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2732329). Since that publication, there were several confirmatory studies that failed to show a benefit in important outcomes such as overall survival or progression-free survival, and the US FDA made some revisions to certain checkpoint inhibitor drug labels. This prompted us to re-evaluate the eligibility of these drugs. (more…)
Author Interviews, Colon Cancer, JAMA, Weight Research / 13.03.2020

MedicalResearch.com Interview with: Dr Laurent Bailly MD, PhD Département de Santé Publique, CHU Nice, Hôpital Archet 1. Niveau1 NICE France  MedicalResearch.com: What is the background for this study? Response: Obesity is known to increase cancer incidence and notably colorectal cancer incidence. Bariatric surgery is an effective treatment of obesity however the association of this surgery with the colorectal cancer remained controversial. We used the French National Health Insurance Information System to conduct a nationwide retrospective cohort study, between 2009 and 2018, of patients hospitalized in France with a diagnosis of obesity. We followed more than 1 million obese individuals aged 50 to 75 years and free of colorectal cancer at baseline, some of them did undergo bariatric surgery and others did not. (more…)
Author Interviews, Hepatitis - Liver Disease, JAMA, USPSTF / 12.03.2020

MedicalResearch.com Interview with: Dr. Michael Barry MD Director of the Informed Medical Decisions Program Health Decision Sciences Center at Massachusetts General Hospital Physician at Massachusetts General Hospital Professor of Medicine,Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Hepatitis C affects more people today than ever before, many of whom are younger. If left untreated, it can cause serious, lifelong health problems due to liver damage. The good news is that hepatitis C infection is both preventable and treatable, with recent evidence showing that new treatments for adults are highly effective. Knowing this, we’ve broadened our guidelines to recommend screening for hepatitis C in all adults between the ages of 18 and 79. (more…)
Author Interviews, Cost of Health Care, JAMA, NIH, Social Issues / 12.03.2020

MedicalResearch.com Interview with: Dr. Adan Z. Becerra PhD Senior Epidemiologist for the  NIH Social and Scientific Systems Washington, District Of Columbia MedicalResearch.com: What is the background for this study? Response: Previous studies have shown that disparities in insurance coverage by immigration status exist in the United States such that immigrants compared to nonimmigrants are less likely to have insurance. However, most studies have been cross sectional with few studies investigating long term trajectories of insurance coverage over time. We addressed this gap in the literature by following a cohort of adults for 24 years from before until after reaching Medicare age-eligibility. (more…)
Author Interviews, Beth Israel Deaconess, Brigham & Women's - Harvard, Cost of Health Care, Geriatrics, JAMA, Medicare / 12.03.2020

MedicalResearch.com Interview with: Rishi K. Wadhera, MD Harvard Medical Faculty Physicians Cardiovasular Diseases Beth Israel Deaconess Medical Center  MedicalResearch.com: What is the background for this study? Response: In the U.S., income inequality has steadily increased over the last several decades. Given widening inequities, there has been significant concern about the health outcomes of older Americans who experience poverty, particularly because prior studies have shown a strong link between socioeconomic status and health. In this study, we evaluated how health outcomes for low-income older adults who are dually enrolled in both Medicare and Medicaid have changed since the early 2000’s, and whether disparities have narrowed or widened over time compared with more affluent older adults who are solely enrolled in Medicare (non-dually enrolled).

Alcohol, Author Interviews, Brigham & Women's - Harvard / 11.03.2020

MedicalResearch.com Interview with: John F. Kelly, Ph.D., ABPP. Recovery Research Institute Elizabeth R. Spallin Professor of Psychiatry in Addiction Medicine Harvard Medical School   MedicalResearch.com: What is the background for this study? Response: Alcohol use disorder is one of the leading causes of disease, disability, and preventable death worldwide. Alcoholics Anonymous (AA) is a widespread international recovery support organization designed to address it. While it has remained popular and influential for many decades, until recently the quantity and quality of the research on AA and clinical treatments designed to stimulate AA involvement – Twelve-Step Facilitation (TSF) treatments – had not been evaluated adequately. This systematic review and meta-analysis used the rigor of the Cochrane review system to subject AA/TSF to the same scientific standards as other clinical interventions.   (more…)

MedicalResearch.com Interview with: Olivier Wouters, Ph.D. Assistant Professor of Health Policy Department of Health Policy London School of Economics and Political Science London MedicalResearch.com: What is the background for this study? Response: Although both Democrats and Republicans consider lowering prescription drug prices a priority, lobbyists and campaign donors in the pharmaceutical industry may counteract efforts by federal and state governments to decrease these costs. In this study, I tracked every dollar spent by the pharmaceutical and health product industry on lobbying and campaign contributions in the US from 1999 to 2018. These data were obtained from the Center for Responsive Politics and the National Institute on Money in Politics—two non-profit, non-partisan US organizations.  (more…)
Allergies, Asthma, Author Interviews, Dermatology, Pediatrics / 10.03.2020

MedicalResearch.com Interview with: Marcella Aquino, M.D. Hasbro Children's Hospital Department of Pediatrics Division of Allergy & Immunology Associate Professor of Pediatrics   Daphne Koinis-Mitchell PhD Professor (Research) in the Departments of Psychiatry and Human Behavior and Pediatrics Warren Alpert Medical School of Brown University Providence, Rhode Island 02903   MedicalResearch.com: What is the background for this study? Response: Urban minority children with asthma are at increased risk for sleep loss and poorer sleep quality secondary to socio-contextual stressors (poverty, stressors of urban living) and the underlying challenges related to following possibly complex asthma treatment regimens. Atopic dermatitis (AD) is very frequently seen in children with asthma and increases the risk for poor quality sleep, for example difficulty falling asleep, awakenings during the night, difficulty awakening in the morning, and/or daytime sleepiness.  (more…)
Author Interviews, Fertility / 10.03.2020

MedicalResearch.com Interview with: Dr. Julia Stern (Jünger) Georg-August-University Göttingen Georg-Elias-Müller-Institute of Psychology Biological Personality Psychology Göttingen  MedicalResearch.com: What is the background for this study? Response: The main background for this study was the Good Genes Ovulatory Shift Hypothesis. This Hypothesis is quite famous in evolutionary social sciences. It claims that women’s mate preferences should shift across their ovulatory cycle, regulated by changing hormone levels (mainly estradiol and progesterone). More precisely, when fertile, women should be sexually attracted to men who displayed assumed indicators of genetic quality, e.g. dominant behavior, whereas when not fertile, women should prefer to mate with potential long-term partners. This Hypothesis has received criticism in the recent years, because of studies not finding any evidence for it, studies with positive evidence were criticized for methodological problems, and studies claiming that previously presumed indicators of good genes do not really display good genes at all. All this criticism led to a debate about the existence of mate preference shifts across women’s ovulatory cycle. My colleagues and I wanted to contribute to this debate by conducting a large study with strong research methods. (more…)
Author Interviews, Biomarkers, Lung Cancer, Stanford / 09.03.2020

MedicalResearch.com Interview with: Professor Dr. Andreas Keller Stanford University School of Medicine Office Department of Neurology and Neurological Sciences Chair for Clinical Bioinformatics Saarbrücken, Germany MedicalResearch.com: What is the background for this study? Response: Lung cancer is among the three most common cancers and the leading cause of cancer-related deaths worldwide. The overall low survival rate of patients with lung cancer calls for improved detection tools to enable better treatment options and improved patients’ outcomes. To detect lung tumors, liquid biopsy-based strategies are increasingly explored, that are biomarkers, which are identifiable in body fluids such as human blood. The clinical application of biomarkers is, however, largely hampered by the relatively small numbers of cases that have been analyzed in the majority of the preclinical studies including the studies on lung cancer.  (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition, Social Issues / 09.03.2020

MedicalResearch.com Interview with: Alon Peltz, MD MBA MHS  Department of Population Medicine Harvard Pilgrim Health Care Institute MedicalResearch.com: What is the background for this study? Response: Thank you for taking an interest in our study. This study represented a collaboration between investigators from Harvard Medical School and Boston University School of Medicine. SNAP is an important U.S. federal aid program that serves nearly 40 million persons annually with well-established health, nutrition, and financial benefits. Families can be eligible for the SNAP program under “federal” rules or “categorical eligibility” rules that extend SNAP support to otherwise ineligible families who receive benefits under certain social assistance programs, such as Temporary Assistance for Needy Families. In July 2019, the U.S. Department of Agriculture proposed new SNAP policies that would limit qualifications via the categorical eligibility route. Although these new policies have not been finalized, it is estimated that 1 in 10 U.S. families currently participating in SNAP may lose their benefits. We wanted to investigate the potential ramifications of these changes to help inform policymakers of the vulnerabilities of the families who receive SNAP benefits and may be at risk for disenrollment if the proposed policies are implemented.

MedicalResearch.com Interview with: Robert F. Heary, M.D. Co-Director, Reynolds Family Spine Laboratory Director, Spine Center of New Jersey Professor, Rutgers New Jersey Medical School Newark, New Jersey MedicalResearch.com: What is the background for this study? Response: This article was written to assess the relative danger versus safety of youth football.  As this is a hot-button topic in the world of neurosurgery and neurology, we decided to look into this issue. In a suburban town, middle school football players were studied.  They wore helmets with accelerometers mounted inside the hemet to measure how many hits the player absorbs and the magnitude of the force behind the hits.  Also, soft “guardian caps” we worn over the outside of the helmets during practices. For all football activities (practices and games), the helmets were worn and data were accumulated.  In addition, specialized coaching related to safe tackling techniques was provided. (more…)
Author Interviews, Compliance, Electronic Records, JAMA, University of Pennsylvania / 05.03.2020

MedicalResearch.com Interview with: Alexander C. Fanaroff, MD, MHS Assistant Professor of Medicine, Division of Cardiovascular Medicine University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: This is a secondary analysis of the ARTEMIS, a cluster randomized trial of copayment assistance for P2Y12 inhibitors in patients that had myocardial infarction. One of the primary endpoints of ARTEMIS was persistence with P2Y12 inhibitors: Did the patient continue to take a P2Y12 inhibitor over the entire 1 year following MI? In ARTEMIS, we captured persistence data in two ways, patient report and pharmacy fill records. What we did in this study was to look at the agreement between persistence as measured by these two methods. (more…)
Author Interviews, BMJ, Brigham & Women's - Harvard, Heart Disease, Nutrition / 05.03.2020

MedicalResearch.com Interview with: Jean-Philippe Drouin-Chartier, RD PhD Assistant Professor, Faculty of Pharmacy, Université Laval Researcher, NUTRISS Center of INAF, Université Laval Visiting Scientist, Department of Nutrition Harvard TH Chan School of Public Health  MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease (CVD) is a leading cause of death worldwide. Eggs are a major source of dietary cholesterol, but they are also an affordable source of high-quality protein, iron, unsaturated fatty acids, phospholipids, and carotenoids. However, because of the cholesterol content in eggs, the association between egg intake and CVD risk has been a topic of intense debate in the past decades. Many prospective studies on the association between egg intake and cardiovascular disease risk have provided conflicting findings. The aim of our study was to prospectively examine the association between egg consumption and risk of CVD in three cohorts of US men and women, and to conduct a systematic review and a meta-analysis of prospective cohort studies on eggs and CVD.  (more…)

MedicalResearch.com Interview with: Olivier Wouters, Ph.D. Assistant Professor of Health Policy Department of Health Policy (COW 2.06) London School of Economics and Political Science MedicalResearch.com: What is the background for this study? What are the main findings? Response: Drug companies often point to high research and development costs as justification for the rising prices of new medicines. Yet most prior analyses of research and development costs have been based on confidential data voluntarily supplied by drug companies to researchers with financial ties to the industry. Independent teams have not been able to verify those findings. (more…)
Author Interviews, Cost of Health Care, JAMA, University of Pittsburgh / 04.03.2020

MedicalResearch.com Interview with: Inmaculada Hernandez, PharmD, PhD Assistant Professor of Pharmacy and Therapeutics University of Pittsburgh School of Pharmacy MedicalResearch.com: What is the background for this study? Response: Prior research found that list prices of drugs more than doubled in the last decade. However, because prior research was based on list prices, it did not account for manufacturer discounts, which have also increased in the past few years. We leveraged net pricing data from the investment firm SSR health to estimate increases in drug prices after accounting for discounts. (more…)
Accidents & Violence, Author Interviews, Brigham & Women's - Harvard, JAMA, Pediatrics / 03.03.2020

MedicalResearch.com Interview with: Hooman Azad First author and a 3rd year medical student Feinberg School of Medicine Northwestern University Eric Fleegler, MD MPH FAAP Senior author and Pediatric Emergency Physician Boston Children’s Hospital Assistant Professor of Pediatrics and Emergency Medicine Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Pediatric firearm violence is a public health crisis. The firearm fatality rate has increased by >50% over the past 10 years. Over our 26-year study period (1991-2016), 13,697 children under the age of 15 died at the hands of a firearm. Laws have been employed to try to reduce these deaths, and Child Access Prevention (CAP) laws, which aim to hold parents liable for the safe storage of their firearms, were passed in 25 states between 1989-2000. No new state passed a CAP laws after the year 2000. Child Access Prevention laws come in two flavors – recklessness laws that hold firearm owners liable for directly providing firearms to a minor, and negligence laws that hold the firearm owner liable for the unsafe storage of firearms with variability in how storage is defined and what penalties are imposed.

Author Interviews, Nutrition, Pediatrics, Sugar / 03.03.2020

MedicalResearch.com Interview with: Lori Spruance PhD Assistant Professor, Public Health College of Life Sciences Brigham Young University MedicalResearch.com: What is the background for this study? Response: I was interested in studying this phenomenon after I attended a research conference presentation where the presenter was describing results from a study where they found that children between ages 6-11 who were physically active drank more sugar-sweetened beverages than children in that age group who were not physically active. The presenter suggested that they believed this was due to youth sports and Gatorade consumption. I was really intrigued by the fact that kids were getting physical activity, but had really high sugar-sweetened beverage intake. Prior to the study, I did some qualitative interviews with parents of children involved in youth sports. During these interviews, parents discussed the “snack culture” and the shame they sometimes feel being the “healthy parent”. I really wanted to investigate further what was happening. (more…)
Author Interviews, Heart Disease, Omega-3 Fatty Acids / 03.03.2020

MedicalResearch.com Interview with: Lee Hooper PhD, RD Reader in Research Synthesis, Nutrition & Hydration Norwich Medical School Norwich, UK  MedicalResearch.com: What is the background for this study? Response: Polyunsaturated fats are common healthy eating choices, and fish oil (long-chain omega-3 including EPA and DHA) and flaxseed (containing alpha-linolenic acid, ALA, a plant-based omega-3) supplements are commonly consumed. Worldwide cardiovascular disease was responsible for 37% of premature deaths due to non-communicable disease in 2012, and cancers were responsible for 27%.  Small effects of omega-3 and polyunsaturated fats on cardiovascular diseases and cancers could have big effects on worldwide health.
