MedicalResearch.com Interview with: [caption id="attachment_53388" align="alignleft" width="180"]Alexander C. Fanaroff, MD, MHS Assistant Professor of Medicine, Division of Cardiovascular Medicine University of Pennsylvania Dr. Fanaroll[/caption] 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.

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.

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.

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.

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.

Response: Diuretics are considered among the best drugs to treat hypertension, but there are no randomized studies to tell us which diuretic is best. Hydrochlorothiazide is the most frequently used diuretic for hypertension, but another drug, chlorthalidone, is gaining favor, with the most recent US hypertension guideline expressing a preference for it. Chlorthalidone is known to be longer acting and therefore perhaps more effective. Other (non-randomized) studies have been inconsistent, and some of them imply that chlorthalidone may be more effective. But other studies have shown that chlorthalidone may have more side effects.

Would you briefly explain what is meant by Hidden Hearing Loss? Response: Our ears were not designed for the society our brains created. The World Health Organization estimates that 1 billion young adults are at risk for hearing loss due to prolonged exposure to excessive environmental noise. Anatomical analysis of human ears has shown that half of the nerve fibers connecting the ear to the brain have degenerated by the time we reach 40 years of age. Many of us experience the first symptoms of hearing loss as a difficulty following conversations in crowded places such as restaurants. Hidden hearing loss is an umbrella term used to describe such hearing difficulties experienced by people who show no abnormalities on any of the current tests of hearing used in the clinic. Approximately 10% of visitors to our hospital hearing clinic fit this profile, arriving with a primary complaint of poor hearing but being sent home with a clean bill of hearing health.

Response: While U.S. adults age 50-64 previously had more limited options for health insurance before Medicare at age 65, the Affordable Care Act expanded the number of options, including Marketplace plans (e.g., through HealthCare.gov) and Medicaid. This expanded set of options may complicate decisions about health insurance near retirement. In addition, several policy challenges to the Affordable Care Act may add uncertainty to the decision-making process.

Litonjua, M.D., M.P.H. Professor - Department of Pediatrics, Pulmonology Interim Chief - Department of Medicine , Pulmonary Diseases and Critical Care Professor - Department of Medicine , Pulmonary Diseases and Critical Care University of Rochester MedicalResearch.com: What is the background for this study? Response: Vitamin D deficiency and insufficiency is prevalent worldwide. Prior observational studies have shown that low vitamin D levels have been associated with the development of asthma. Animal studies have reported that antenatal vitamin D is important for lung development in utero. Thus, we conducted a randomized, double-blind, controlled trial of vitamin D supplementation in pregnant women to see if we could prevent the development of asthma and wheezing illnesses in young children. The initial report of the trial results showed that children born to mothers in the vitamin D supplementation arm had lower risks for developing either asthma or recurrent wheezing episodes over the first 3 years, but this was not statistically significant (p=0.051)(Litonjua et al. JAMA 2016).

El Khoudary, M.D., M.P.H. Associate Professor of Epidemiology and Saad Samargandy, M.P.H. Ph.D. Student University of Pittsburgh Graduate School of Public Health MedicalResearch.com: What is the background for this study? Response: Research findings suggest that women experience adverse changes in multiple clinical measures of their cardiovascular health during the menopause transition period. We were interested in evaluating the timing of critical changes in arterial stiffness and investigating potential racial differences in how arterial stiffness progresses during the menopause transition. Arterial stiffness refers to the elasticity of arteries and it measures the rate at which blood flows through arteries. Stiffer arteries can lead to dysfunction in how well the heart pumps and moves blood, and damage to the heart, kidneys and other organs. We used a subset of data from SWAN Heart, an ancillary study that enrolled women from Pittsburgh and Chicago between 2001 and 2003 and included two examinations of early markers of cardiovascular health over time. Ultimately, 339 women were included in this study, 36% black and the rest white.

Response: As background, two main points:
  • Almost all molecular (gene expression) analyses performed in neurodegeneration are based on snapshots data, taking at one or a few time points covering the disease's large evolution. Because neurodegenerative diseases take decades to develop, until now we didn't have a dynamical characterization of these diseases. Our study tries to overcome such limitation, proposing a data-driven methodology to study long term dynamical changes associated to disease.
Also, we still lacked robust minimally invasive and low-cost biomarkers of individual neuropathological progression. Our method is able to offer both in-vivo and post-mortem disease staging highly predictive of neuropathological and clinical alterations.

Response: Industry spends more on detailing visits and free samples than any other form of prescription drug marketing.  There is good evidence that these activities can lead to more use of expensive new drugs over equally effective cheaper options.  Given these concerns there have been efforts by some hospitalls and practices to restrict these forms of marketing. We asked physicians in group practices delivering primary care about how often pharmaceutical reps visit their practice and whether they have a free sample closet.

MedicalResearch.com Interview with: [caption id="attachment_52973" align="alignleft" width="133"]Allison Brashear, M.D., M.B.A. Dean, UC Davis School of Medicine Dr. Brashear[/caption] Allison Brashear, M.D., M.B.A. Dean, UC Davis School of Medicine MedicalResearch.com: What is the background for this study? Why is the demand for neurology services and neurologists increasing?  Response: The American Academy of Neurology estimates that by 2025 the number of neurologists in practice will increase to 18,060 but some 3,400 more will be needed to meet the demand for their services. The 58% increase in the number of residency positions in the National Resident Matching Program since 2008 also reflects the growing demand. The higher prevalence of neurologic conditions, aging U.S. population and more patients having access to the health care coverage are the major driving forces. (Note: source of NRMP neurology trend data comes from a physician/resident forum posted May 2019 https://forums.studentdoctor.net/threads/growth-trends-in-neurology-residency-positions.1375918/) MedicalResearch.com: Why is neurology included among the less desirable fields of medicine (similar to nephrology, infectious disease, endocrinology etc.) for medical students and residents to pursue?  Why is burnout and dissatisfaction so high? Response: According to the American Academy of Neurology, a minority of medical students choose to train in neurology each year, with approximately 3.1% matching into a neurology residency in 2018. The newer generations of neurologists value lifestyle and time off work more than their predecessors. According to a recent American Medical Association survey, neurology tied with critical care as the medical specialty with the highest stress levels and burnout. Too many administrative tasks, too many hours at work, increased computerization of practice and insufficient compensation were among the top causes of burnout.

Response: The blood pressure (BP) guideline in the US recommend using an “average” of multiple BP measurements over time for screening for and management of high BP in young adults. While it is well known that BP varies across visits, that “variability” (i.e., visit-to-visit blood pressure variability) is dismissed as a random fluctuation in the clinical setting. Little is known regarding the clinical relevance of visit-to-visit blood pressure variability over time in young adults.

Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Long-standing controversies have focused on the health consequences of dietary fat and carbohydrate. Previous evidence has shown that different types of carbohydrates and fats have varying effects on disease risk and health. For example, carbohydrates from refined grains and added sugars may contribute to insulin resistance and other metabolic problems while carbohydrates from whole grains and whole fruits appear to be beneficial. Likewise, replacing saturated fat with unsaturated fat was associated with lower risk of heart disease and mortality. Therefore, it is crucial to incorporate quality and types of carbohydrate and fat when investigating the associations of low-fat and low-carbohydrate diets with mortality.

Response: Clinical guidelines for prostate cancer, circulated widely in the public domain, endorse the consumption of diets high in micronutrient-enriched vegetables. Drawing on expert opinion, epidemiological studies, and small preclinical experiments, these recommendations propose that vegetable-enriched diets may decrease cancer progression and death among prostate cancer survivors. However, data from randomized clinical trials focused on actionable clinical endpoints has been lacking. We utilized a specific behavioral intervention, grounded in the field of social psychology, to “nudge” patients with prostate cancer toward healthier food choices. The intervention is telephone-based, like a call center: patient-focused, convenient, and simple.

Response: There are concerns that robotic surgery is increasing for common surgical procedures with limited evidence and unclear clinical benefit. Prior studies describing the use of robotic surgery relied upon claims or billing data to identify robotic operations from laparoscopic or open ones. This may lead to inaccuracies as claims data may not provide specific codes for robotic operations.

Cengel, M.D., Ph.D. Associate Professor of Radiation Oncology Hospital of the University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: FLASH radiotherapy involves delivering the treatment dose at a rate that is 1000s of times faster than standard radiotherapy.  Scientists have studied the differential biological effects of various dose rates for dose rates for the past ~80 years, but the unique effects of FLASH dose rates have only been appreciated in the last few years. While the mechanism(s) and applications of FLASH radiotherapy remain an area of active investigation,  t is clear so far that FLASH dose rates can provide similar levels of tumor control with less toxicity to normal tissues when compared to the same dose of radiotherapy delivered at a standard dose rate.
