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…)

Author Interviews, Cost of Health Care, JAMA, Pharmaceutical Companies / 04.03.2020

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.

Addiction, Author Interviews, JAMA, Pediatrics / 02.03.2020

MedicalResearch.com Interview with: Karl Alcover, PhD Postdoctoral Research Associate Behavioral Health Innovations Washington State University MedicalResearch.com: What is the background for this study? Response: It has been a public health focus to prevent early exposure to drugs. Our paper shows that the average age of initiation of drug use among adolescents and young adults has been increasing from 2004 to 2017. We found that 12 of 18 drugs (including alcohol and tobacco products) had statistically increasing average ages of initiation. To our knowledge, no studies have documented these findings. We think this is great news because delaying initiation of drugs prevents early exposure, which we know is associated with various long-term negative health outcomes. Also, these promising trends may serve as initial evidence that prevention strategies, especially those that focus on adolescents and young adults, are working. (more…)
Alzheimer's - Dementia, Author Interviews, Hearing Loss / 28.02.2020

MedicalResearch.com Interview with: Julia Sarant, PhD Associate Professor Department of Audiology and Speech Pathology Faculty of Medicine, Dentistry and Health Sciences Melbourne School of Health Sciences MedicalResearch.com: What is the background for this study? Response: Dementia is a rapidly growing global problem. Hearing loss has been identified by the Lancet Commissions as a modifiable risk factor for dementia. There is no treatment for dementia. This study investigated the effect of hearing aid use on cognition over time in older adults, objectively assessing hearing loss treatment, compliance and benefits while controlling for the effects of other known risk factors for dementia.  (more…)
Asthma, Author Interviews, Genetic Research, Nature / 28.02.2020

MedicalResearch.com Interview with: Zbigniew Zasłona PhD Luke A. J. O’Neill PhD Professor (Chair of Biochemistry) School of Biochemistry and Immunology Trinity Biomedical Sciences Institute Trinity College Dublin, Dublin, Ireland  MedicalResearch.com: What is the background for this study? Response: Asthma is the most common disease in childhood and the most common respiratory condition in Ireland. It is a disease of environmental and genetic components. It is important to point out that although Ireland has very good air quality, asthma prevalence is very high (the second highest in Europe), and although asthma is not a single gene disease (such as cystic fibrosis) it is very important to study genetic variations in Irish population. Therefore in this study we put emphasis on the genetic component of asthma, rather than environmental factors, especially given that asthma heritability has been estimated as high as 60%. Prevention of asthma by reducing exposure to common risk factors, such as air pollution, will not stop the asthma epidemic in Ireland, as inferior air quality is not an issue. (more…)
Author Interviews, JAMA, Mental Health Research / 28.02.2020

MedicalResearch.com Interview with: Dr. Aristotle Voineskos MD, PhD, FRCPC Director, Slaight Family Centre for Youth in Transition and Head, Kimel Family Translational Imaging-Genetics Laboratory Campbell Family Mental Health Research Institute CAMH University of Toronto MedicalResearch.com: What is the background for this study? Response: Uncontrolled studies in humans have shown conflicting results regarding effects of antipsychotic medications on brain structure. Recent studies in animals (e.g. rats and non-human primates) show that these medications may be associated with brain volume loss. To date, our knowledge of the effects of antipsychotic medications on brain structure in humans have been limited by the lack of a double-blind, randomized, placebo-controlled trial with brain imaging. Ours is the first such study. It is considered unethical to do such a study in people with schizophrenia, because of the life-saving benefits of these medications in this illness. However, in people with depression also experiencing psychosis, it was possible to do such a study once people experienced remission from their illness. (more…)
Author Interviews, Dermatology, Immunotherapy, Science / 27.02.2020

MedicalResearch.com Interview with: Brian S. Kim, MD, MTR, FAAD Associate Professor of Medicine (Dermatology) Co-Director, Center for the Study of Itch and Sensory Disorders Division of Dermatology, Department of Medicine Washington University School of Medicine St. Louis, MO 63110 MedicalResearch.com: What is the background for this study? Response: It has been known well for decades that a specific part of your immune system called the “type 2 immune response” is overactive in atopic disease. Indeed, that is what new drugs like dupilumab block so effectively and thus revolutionized the treatment of atopic disorders just in the last few years. In fact, our lab focuses predominantly on this part of the immune system. However, increasingly it is becoming recognized that the immune system is not just about whether it is “on or off” but rather a balance like yin and yang. Along these lines, we noticed that a cell that could theoretically counterbalance atopic inflammation was significantly deficient in many patients with eczema. This cell is the natural killer (NK) cell. (more…)
Author Interviews, BMC, Breast Cancer, Cancer Research, Weight Research / 27.02.2020

MedicalResearch.com Interview with: Carolyn Ee PhD NICM Health Research Institute Western Sydney University Australia MedicalResearch.com: What is the background for this study? Response: Worldwide and in Australia, breast cancer is the most common cancer in women. Weight gain is common after diagnosis of breast cancer and may increase tumour recurrence risk, mortality rate, and worsen quality of life. As there was no national data on the prevalence of weight gain after breast cancer in Australia, we undertook a national survey which was open to any woman living in Australia who had breast cancer.

Donovan, M.D. Chief, Division of Geriatric Psychiatry Brigham and Women’s Hospital Assistant Professor of Psychiatry Harvard Medical School Boston, MA 02115  MedicalResearch.com: What is the background for this study? Response: Prior research has shown that widowed older adults are more likely to experience cognitive decline than those who are married. However, there have been no prior studies of widowhood as a risk factor for cognitive decline due to Alzheimer’s disease, the most common cause of severe cognitive impairment. (more…)
Author Interviews, Heart Disease, JACC, Women's Heart Health / 26.02.2020

MedicalResearch.com Interview with: Haider Aldiwani, MD Fellow in Internal Medicine and C. Noel Bairey Merz, MD, FACC, FAHA Director Barbra Streisand Women’s Heart Center Smidt Heart Institute, Cedars-Sinai Medical Center Los Angeles, CA, 90048   MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease is the leading cause of death in women in the United States. Women are found to have a higher prevalence of ischemia but no obstructive coronary artery disease (INOCA) compared to men. These women are often labeled as “normal” and their symptoms and cardiovascular risk are not managed appropriately. Women with INOCA are higher risk of developing major adverse cardiovascular events including death, myocardial infarction (MI), stroke and heart failure hospitalization. Presenting symptoms of ischemia are variable and more often labelled “atypical” in women.  (more…)

MedicalResearch.com Interview with: Prof. Konstantinos Stellos, MD, DM, MRCP, DSc, FAHA, FESC Professor of Medicine, Chair of Cardiovascular Medicine, Chair of Epitranscriptomics Lead, Vascular Biology & Medicine Theme Hon. Consultant Cardiologist, Newcastle Hospitals NHS Foundation Trust Biosciences Institute Faculty of Medical Sciences Newcastle University MedicalResearch.com: What is the background for this seminar? Can you tell us a little about how amyloid is made and stored? Response: Patients are afraid that they may die due to a heart attack - a major cause of death worldwide- or if they live long they may get dementia compromising severely their quality of life in their last years of life. Many years ago we asked the question whether there is a link between these two ageing-associated diseases. For this reason we studied the clinical value of amyloid-beta peptides in patients with coronary heart disease. We chose to study the amyloid-beta peptides, which are the cleavage product of the beta- and gamma-secretases of the mother protein amyloid precursor protein, because amyloid-beta plaques in brain is the hallmark of Alzheimer's disease. Following amyloid precursor protein (APP) gene transcription, APP is cleaved in the nonamyloidogenic pathway (plasma membrane) by α- and γ- secretases or in the amyloidogenic pathway (endosomes) by β- and γ- secretases. The later pathway generates amyloid beta (Αβ) peptides that are released extracellularly. Αβ accumulation in blood or tissues may result from enhanced production/cleavage or by impaired degradation and/or clearance. The related mechanisms are depicted in Figure 2 of our publication in JACC: http://www.onlinejacc.org/content/75/8/952  (more…)
Annals Internal Medicine, Author Interviews, Breast Cancer, Brigham & Women's - Harvard, Cancer Research, Mammograms / 25.02.2020

MedicalResearch.com Interview with: Xabier Garcia-De-Albeniz MD PhD Research Associate Department of Epidemiology Harvard T.H. Chan School of Public Health Mongan Institute for Health Policy Massachusetts General Hospital  MedicalResearch.com: What is the background for this study? Response: The goal of breast cancer screening is to reduce deaths from breast cancer by finding breast cancer at early, more treatable stages. The main way to screen for breast cancer is periodic mammography, which is an x-ray of the breast that can show tumors before they are large enough to feel. High-quality studies called clinical trials have shown that screening women in their 50s and 60s decreases breast cancer deaths. However, the point at which women can safely stop screening because it no longer decreases breast cancer deaths has not been studied. More than half of women in the United States continue screening mammography after age 75 years.  (more…)
