Author Interviews, JAMA, Sleep Disorders, Stanford / 07.07.2020

MedicalResearch.com Interview with: Eileen B. Leary, Ph.D. Student Epidemiology and Clinical Research Stanford University MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by REM sleep? Response: Sleep is a regulated, reversible, and recurring loss of consciousness that is a critical requirement for a happy, healthy life. REM sleep is an important component of sleep defined by rapid eye movements and commonly associated with dreaming. We learned from previous studies that sleep duration is associated with mortality, however little was known about how the different sleep stages relate to timing or cause of death. (more…)

MedicalResearch.com Interview with: Erin Brantley, PhD, MPH Senior Research Associate Department of Health Policy and Management Milken Institute School of Public Health Preferred pronouns: she/her/hers  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We looked at what happened when work requirements for the Supplemental Nutrition Assistance Program Participation, or SNAP, were turned on in many places after the Great Recession. We found large drops in participation in SNAP benefits due to work requirements, and that black recipients were more likely to lose benefits than white recipients. We think this is driven by the fact that black workers face higher unemployment rates than white workers, and work requirement policies do not take this into account. We also found that some people who report having disabilities lost benefits, even though the intent of work requirements is that they apply to people without disabilities.  (more…)
Author Interviews, COVID -19 Coronavirus, Dermatology, Environmental Risks, JAMA / 26.06.2020

MedicalResearch.com Interview with: Dr Herman Anne MD Service de Dermatologie Cliniques Universitaires Saint-Luc   MedicalResearch.com: What is the background for this study? Response: In the context of the COVID-19 pandemic, several cases of acro-located lesions (on foot or hands) suggestive of chilblains have been reported and were possibly related to COVID-19. We wanted to determine if chilblains, observed in many patients recently referred to our department, are indicative of COVID-19. MedicalResearch.com: Would you briefly explain what is meant by chilblains? Response: Chilblains are frequent cold induced inflammatory lesions. Chilblains are typically seen in winter and occur after repeated exposure to cold temperatures. Clinical presentation includes erythema and swelling on toes and/or digits followed by red-purple macules or patches. However, given the large number of patients affected, and the exceptionally high outdoor temperatures for the spring season over the past month and at the time of case-observation, cold-exposure seemed unlikely. These lesions were, therefore, suspected to be associated with COVID-19. However, to date, no study has proven a pathological link between these lesions and COVID-19. (more…)

MedicalResearch.com Interview with: Robert Wong, MD, MS Division of Gastroenterology and Hepatology Veterans Affairs Palo Alto Healthcare System Stanford University School of Medicine MedicalResearch.com: What is the background for this study? Response: Prior to this study, we already knew that obesity and metabolic syndrome were major public health issues in the U.S.  A previous analyses by our team which analyzed data through 2012 observed than one in three adults in the U.S. have metabolic syndrome.  The aim of our current study was to evaluate more recent trends in the prevalence of metabolic syndrome and to identify whether certain groups are at higher risk of having metabolic syndrome.  (more…)

MedicalResearch.com Interview with: Megan B. Cole Brahim, PhD, MPH Assistant Professor | Dept. of Health Law, Policy, & Management Boston University School of Public Health Boston, MA MedicalResearch.com: What is the background for this study? Response: Enrollment in high deductible health plans (HDHPs)—which require patients to pay on the upwards of thousands of dollars in out-of-pocket costs before they can use their health insurance coverage for most services—has skyrocketed over the last decade. For cancer survivors in particular, this is really concerning, as patients may avoid or delay necessary health care services or important medications because they can’t afford their deductible. We know from previous work that HDHPs are associated with less use of health care, including less cancer screening and treatment. However, there has been very little work to assess how HDHPs may contribute to racial/ethnic disparities in care, and our study is the first known study to assess how HDHPs may contribute to racial/ethnic disparities in cancer survivors. To fill this gap, we used nationally representative survey data from 2013-2018 to assess how enrollment in high deductible health plans was associated with cost-related barriers to care among cancer survivors with private insurance, and how this relationship varied across racial/ethnic groups.

MedicalResearch.com Interview with: Julian Santaella Tenorio, MSc DrPH Epidemiology Center for Opioid Epidemiology and Policy Division of Epidemiology, Department of Population Health New York University Langone School of Medicine, New York, New York MedicalResearch.com: What are the main findings? car-accident-traffic-accidentResponse: This study found that recreational cannabis laws were associated with increases in traffic fatalities in Colorado (mean of 75 excess fatalities per year) but not in Washington State.  These findings suggest that unintended effects of recreational cannabis laws can be heterogeneous and may be specific to variations in how these laws are implemented
(eg, density of recreational cannabis stores).   (more…)

MedicalResearch.com Interview with: Russell Kamer, MD Department of Medicine, New York Medical College, Valhalla 15 North Broadway, Suite E White Plains, NY 10601 New York MedicalResearch.com: What is the background for this study? "marijuana apocalypse - weed is a stimulant !" by Blind Nomad is licensed under CC BY 2.0Response: It is well known that marijuana usage impairs driving ability, yet the early studies of the effects of recreational marijuana legalization on traffic fatalities were inconclusive. MedicalResearch.com: What are the main findings? Response: By analyzing data over a longer time period, we found that the legalization of recreational marijuana increased traffic deaths in the first four states to legalize. Traffic fatalities increased about 20% in those states. If we apply these numbers to the nation as a whole, nationwide legalization would be associated with about 7,000 excess traffic fatalities each year. (more…)
Author Interviews, Heart Disease, JAMA, Opiods, Surgical Research, University of Pennsylvania / 20.06.2020

MedicalResearch.com Interview with: Chase Brown, MD Associate Fellow, Leonard Davis Institute of Health Economics Integrated Cardiac Surgery Resident Hospital of the University of Pennsylvania Nimesh D. Desai, MD, PhD Director, Thoracic Aortic Surgery Research Program Associate Professor of Surgery Hospital of the University of Pennsylvania MedicalResearch.com: What is the background for this study? Dr. Chase Brown:  Opioid use in the United States is a public health emergency. We know that opioids prescribed after general surgery operations to patients who never received them within the year prior to their surgery are at increased risk for continuing to take opioids months later. However, this has not been studied in patients undergoing cardiac surgery, who often times have more severe post-operative pain. Our goal in this study was to determine how many patients after cardiac surgery and are opioid naive are continuing to take opioids within 90-180 days after their surgery.   (more…)

MedicalResearch.com Interview with: Dr. Karina Davidson, PhD Senior Vice President of Research Dean of Academic Affairs Professor of Behavioral Medicine Zucker School of Medicine Hofstra University/Northwell Health Vice Chairmam US Preventive Services Task Force  MedicalResearch.com: What is the background for this study? Response: Drug use is among the most common causes of preventable death, injury, and disability in the United States, with nearly 10 percent of adults reporting unhealthy drug use. This includes the use of illegal drugs, as well as using prescription drugs in ways that are not recommended by a doctor. (more…)
Author Interviews, Diabetes, JAMA / 17.06.2020

MedicalResearch.com Interview with: Richard E. Pratley, MD AdventHealth Samuel E. Crockett Chair in Diabetes Research Medical Director | AdventHealth Diabetes Institute Senior Investigator and Diabetes Program Lead AdventHealth Translational Research Institute  MedicalResearch.com: What is the background for this study? Response: Historically, older individuals with T1D have been underrepresented or excluded from clinical trials. Older individuals with T1D are at particularly high risk for hypoglycemia. Because of their long duration of diabetes, they often have impaired counterregulatory responses and hypoglycemia unawareness. Hypoglycemia in older individuals is particularly dangerous because it can lead to falls and fractures, cognitive impairment and cardiovascular events, including death. There has been the misperception that older individuals are less able to use technology to manage their diabetes.  This study dispelled that notion.   (more…)
Author Interviews, JAMA, Multiple Sclerosis, Neurology / 15.06.2020

MedicalResearch.com Interview with: Cris S Constantinescu,  MD, PhD, FRCP Professor, Division of Clinical Neuroscience Research Group in Clinical Neurology University of Nottingham Queen's Medical Centre Nottingham UK MedicalResearch.com: What is the background for this study? Response: The study is in some way a test of the hygiene or old friends hypothesis, whereby eradication, through improved hygiene, of some parasites that have existed in the human gut for thousands of years and have suppressed inflammatory reactions, leads to an increase in inflammatory conditions. This has been used to explain the increased autoimmune and inflammatory diseases in the developed world. Healthy volunteer studies at the University of Nottingham showed therapeutic hookworm infection to be safe and well tolerated up to about 50 larvae, and then safety studies in people with airway hyperreactivity and inflammatory bowel disease raised no concern. Following a study in Argentina showing that people with MS have milder disease when they have a natural co-existing asymptomatic infection with intestinal parasites, we (Professor Pritchard, immunoparasitologist and myself) decided to test hookworm in MS, and for the first time used 25 larvae in a patient study.

MedicalResearch.com Interview with: Mohammad Sajadi, MD Associate Professor Institute of Human Virology Global Virus Network Center of Excellence University of Maryland School of Medicine Baltimore, MD 21201  MedicalResearch.com: What is the background for this study? Response: Because of geographical proximity and significant travel connections, epidemiological modeling of the epicenter predicted that regions in Southeast Asia, and specifically Bangkok would follow Wuhan, and China in the COVID-19 epidemic. When we saw this did not happen, we suspected that SARS-CoV-2 might be acting like a seasonal respiratory virus.  (more…)

MedicalResearch.com Interview with: Colm Travers, M.D., MSPH Assistant Professor Department of Pediatrics University of Alabama at Birmingham MedicalResearch.com: What is the background for this study? Response: It is known that black mothers are much more likely to deliver preterm and low birth weight infants. The purpose of this study was to determine whether racial/ethnic disparities in care practices and outcomes were decreasing or increasing among extremely preterm infants. These are infants born from 22 to 27 weeks of gestation who have a high risk of death and major illnesses.  (more…)
Author Interviews, Clots - Coagulation, JAMA, Kidney Disease / 09.06.2020

MedicalResearch.com Interview with: Manish M Sood MD FRCPC MSc Jindal Research Chair for the Prevention of Kidney Disease Associate Professor of Medicine, Dept. of Medicine and the School of Epidemiology and Public Health University of Ottawa Scientist, Ottawa Hospital Research Institute Nephrologist, The Ottawa Hospital Ottawa, Ontario, Canada  MedicalResearch.com: What is the background for this study? Response: Early work has suggested a very commonly used antibiotic, clarithromycin, may interfere with the metabolism of the most widely used type of blood thinning medication (called direct oral anticoagulants or DOACs) such that the blood level of the DOAC increases and may place the patient at a higher risk for bleeding.  In our study we looked at patients of advanced age (>66 years old) who were given clarithromycin while on a DOAC in Ontario, Canada. We compared patients on clairthromycin-DOAC to patients given a very similar antibiotic, azithromycin, that does not interfere with the metabolism of DOAC. (more…)

MedicalResearch.com Interview with: Niklas Andersson MS Department of Epidemiology Research Statens Serum Institut Copenhagen S, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Second-generation antihistamines are among the most commonly prescribed drug classes during pregnancy. Fexofenadine is a widely used antihistamine but given the limited fetal safety on the use of antihistamines during pregnancy in general, current clinical guidelines only recommend the use cetirizine and loratadine during pregnancy when needed due to a larger body of fetal safety data for these antihistamines.

MedicalResearch.com Interview with: Anjali Kaimal, MD, MAS, Maternal-Fetal Medicine Specialist Associate Professor in the Departments of Obstetrics Massachusetts General Hospital Miriam Kuppermann, PhD, MPH Professor Vice Chair Clinical and Translational Research Director Program for Clinical Perinatal UCSF MedicalResearch.com: What is the background for this study? What are the main findings? Response: Reducing the rate of cesarean delivery is an important public health goal.  Nearly one third (31.9%) of deliveries in the US are via cesarean, and dramatic increases in the cesarean rate since the 1990s have been associated with substantial increases in maternal morbidity.  One of the reasons for the increased rate of cesarean delivery is the decreasing rate at which women attempt to have a vaginal birth after cesarean (VBAC).  Although having a “trial of labor” (in the hopes of giving birth vaginally) after cesarean is safe, and many women say they would prefer a vaginal delivery, most women who have had a previous cesarean plan a scheduled repeat cesarean delivery.  While some hospitals do not offer trial of labor after cesarean, even at institutions where this is an option. VBAC rates remain low. We created a patient-facing “decision tool” that provides detailed information on both trial of labor and scheduled repeat cesarean, a personalized risk assessment of the likelihood that the a trial of labor would end in a VBAC, and a series of values clarification exercises, to help women think through their options and engaged in informed, shared decision making with their providers.  We then conducted a randomized study in three geographic areas (San Francisco, Boston, and Chicago) to determine whether use of the decision tool affected rates of trial of labor and vaginal birth after cesarean, as well as several aspects of decision quality (knowledge, shared decision making, decisional conflict, and decision satisfaction).   (more…)

MedicalResearch.com Interview with: Kao-Ping Chua, M.D., Ph.D. Assistant Professor, Pediatrics, Medical School Susan B. Meister Child Health Evaluation and Research Center University of Michigan MedicalResearch.com: What is the background for this study? Response: Due to high and rising prices, insulin has become increasingly unaffordable for patients with type 1 diabetes who must pay out-of-pocket for this life-saving medication. Over the past 5 months, many states and insurers have taken steps to cap insulin out-of-pocket spending. For example, Cigna imposed a $25 monthly cap earlier this year. This week, the Centers for Medicare and Medicare Services announced a $35 monthly cap for many Medicare Part D beneficiaries. (more…)
Author Interviews, JAMA, OBGYNE, Pediatrics / 01.06.2020

MedicalResearch.com Interview with: Katri RäikkönenKatri Räikkönen Professor, Department of Psychology and Logopedics University of Helsinski MedicalResearch.com: What is the background for this study? Response: Maternal antenatal corticosteroid treatment is standard care when there is a risk for preterm delivery. The treatment improves the prognosis of babies born preterm. In high-income countries, antenatal corticosteroid treatment has been in routine use for over 30 years. Recommendations and clinical care guidelines for maternal antenatal corticosteroid treatment differ between continents and countries. In Finland the treatment is currently recommended when the risk for preterm delivery is at 34 gestational weeks or less. In select cases, the treatment is recommended even later in gestation. Corticosteroids accelerate fetal maturation, especially in the lungs, and increase the child’s resilience to the stress that results from being born preterm. However, antenatal corticosteroids not only cross the placenta, but also cross the the blood-brain barrier and may harm fetal brain development. We are not aware of previous population-based studies that would have tested if maternal antenatal corticosteroid treatment would be associated with mental and behavioral disorders in children and we are not either aware of studies that would have tested if any associations would be explained by shared genetic or familial factors.

Author Interviews, Blood Clots, Clots - Coagulation, COVID -19 Coronavirus, JAMA / 29.05.2020

MedicalResearch.com Interview with: Dr Tristan Morichau-Beauchant, MD. Intensive Care Unit Centre Cardiologique du Nord Saint-Denis, France MedicalResearch.com: What is the background for this study? Response: During the spread of the COVID-19 epidemic in France, early reports on severe patients stated a highly increased inflammatory response associated with procoagulant changes in coagulation pathways and high D-Dimer levels. Preliminary reports from the intensive care community signaled frequent events of deep vein thrombosis (DVT) among this population. We decided to perform prospectively a venous ultrasonogram of the inferior limbs for all patients with severe COVID-19 pneumonia at admission in our ICU.  All patients had acute respiratory distress syndrome according to the Berlin definition an required mechanical ventilation. Considering the high prevalence of venous thrombosis at admission we repeated a venous ultrasonography after 48 hours if the first exam was normal. All patients received standard anticoagulant prophylaxis since hospital admission. (more…)
Author Interviews, COVID -19 Coronavirus, JAMA / 28.05.2020

MedicalResearch.com Interview with: Soumya Sen PhD McKnight Presidential Fellow Mary & Jim Lawrence Fellow of Carlson School Director of Research, MIS Research Center Associate Professor, Information & Decision Sciences Carlson School of Management University of Minnesota, Minneapolis, MN MedicalResearch.com: What is the background for this study? Response: As the Covid-19 pandemic unfolded across the United States, one of the greatest barriers to understanding the extent of the problem was the lack of reliable and consistent data. Some of the metrics being reported, such as case count and death, are insufficient for hospital capacity planning. Case count is a conservative estimate of the actual number of infected individuals in the absence of community-wide serologic testing, while death count is a lagging metric and insufficient for proactive hospital capacity planning. A more valuable metric for assessing the effects of public health interventions on the health care infrastructure is hospitalizations. Therefore, the Medical Industry Leadership Institute (MILI) and the Management Information Systems Research Center (MISRC) at the Carlson School of Management launched the COVID-19 hospitalization tracking project in March to consistently track and report daily hospitalizations from all reporting states. Tracking daily hospitalization data is a major step forward in quantifying the current impact on local hospital systems, modeling and  forecasting future utilization needs, and tracking the rate of change in the disease severity. It is also useful for understanding the role of health policy interventions in slowing or reducing the impact of the pandemic. (more…)
Author Interviews, Cancer Research, JAMA, Yale / 28.05.2020

MedicalResearch.com Interview with: Daniel J. Boffa, MD Associate Professor of Thoracic Surgery Yale School of Medicine MedicalResearch.com: What is the background for this study? Response: The study examined networks that formed around hospitals that had been previously ranked in the top-50 by US News and World Report.  These top-ranked hospitals have shared their brand with hospitals in their network, which leads some people to believe that the care is the same at top-ranked hospitals and their affiliate hospitals.  We wanted to determine if outcomes after complex surgical procedures were truly the same at affiliate hospitals and top-ranked hospitals.  (more…)
Author Interviews, Gender Differences, JAMA, Surgical Research, University of Pittsburgh / 21.05.2020

MedicalResearch.com Interview with: Sara P. Myers, M.D., Ph.D. University of Pittsburgh School of Medicine  MedicalResearch.com: What is the background for this study? Response: Compared to other fields, medicine, and especially academic surgery and its subspecialties, trail with respect to gender diversity. Considering that these fields were traditionally male-dominated, two issues that may present ongoing challenges to the retention and promotion of women are pro-male bias and negative stereotypes about women. Training specific to pursuing a surgical career begins in residency, so it is important to understand how these issues affect motivation and achievement during this formative period. In our study we first evaluated the association between pro-male bias and research-related career engagement using a survey methodology, and then looked at whether evoking negative stereotypes about women was associated with reduced performance on a simulated technical skill assessment called the Fundamentals of Laparoscopic Surgery (FLS) assessment.  (more…)

MedicalResearch.com Interview with: Alyson Cavanaugh, PT, PhD Joint Doctoral Program in Epidemiology University of California, San Diego/ San Diego State University MedicalResearch.com: What is the background for this study? Response: More than 700,000 total knee replacements are performed annually in the United States, but there is a racial disparity in outcomes after the surgery. If the knee replacement procedure is considered a highly effective treatment, why don't black women present with the same outcomes as whites? Physical function when going into surgery has a large impact on the potential functional outcomes after surgery. Our hypothesis was that black women were presenting to surgery with poorer physical function, which was contributing to poorer functional outcomes after surgery. (more…)
Author Interviews, JAMA, STD / 19.05.2020

MedicalResearch.com Interview with: Barbara Van Der Pol, PhD, MPH President, American STD Association President-Elect, International Society fo STD Research Professor of Medicine & Public Health Director, STD Diagnostics Lab Director, UAB STD Clinical Research Organization University of Alabama at Birmingham Birmingham, AL  35294 MedicalResearch.com: What is the background for this study? Response: For many decades, public health programs focused on control and prevention of sexually transmitted infections (STI) have relied on lab based tests that required a 1-day to 1-week wait for test results.  Efforts to shorten the duration of infection lead to treating at the time of the clinic visit based on the association between certain clinical signs or symptoms and the likelihood of infection. Unfortunately, more than ½ of infected persons do not have signs or symptoms so they receive no treatment until test results are available. Thus, a test that could be performed at the clinical site with a limited wait time would improve the accuracy of treatment and shorten the duration of infection. Such a strategy will hopefully reduce the number of return clinic visits, the possibility of transmission, and the potential for consequences of untreated infection such as infertility.  (more…)

MedicalResearch.com Interview with: James D. Chambers, PhD, MPharm, MSc Associate Professor of Medicine Tufts Medical Center Institute for Clinical Research and Health Policy Studies MedicalResearch.com: What is the background for this study? Response: We know that biosimilars have not had the same uptake in the US as they have had elsewhere. We know that this is in part due to reference product manufacturer tactics to delay biosimilar market entry and patent disputes. In this study we examined whether lack of preferred coverage by commercial health insurers may also play a role. (more…)
Author Interviews, Cost of Health Care, JAMA, Primary Care / 19.05.2020

MedicalResearch.com Interview with: Sara Martin, MD, MSc Santa Rosa Family Medicine Residency Program Santa Rosa, California MedicalResearch.com: What is the background for this study? Response: To improve access to comprehensive primary care, we need to understand how much is being spent on primary care. Until recently, the United States lacked any data-based estimate of primary care expenditure.  This study utilizes Medical Expenditure Panel Survey (MEPS)data from 2002 – 2016 to estimate the percentage of healthcare expenditures that was spent on primary care. Most discussions around health care expenditure in the U.S. focus on the fact that we spend more than any other country and do not have the corresponding outcomes to match that investment.  This paper focuses the conversation around the distribution of the expenditure.

MedicalResearch.com Interview with: Pooja S. Tandon, MD, MPH Center for Child Health, Behavior and Development Seattle Children's Research Institute MedicalResearch.com: What is the background for this study? Response: Cell phone use is common among middle and high school students, yet we do not have an understanding of school cell phone policies and practices in the U.S. We conducted a survey of public schools serving grades 6-12. The survey sent to over 1,100 school principals, representing a national sample of schools across the U.S., asked questions about the presence of a cell phone policy for students and staff and restrictions on phone use. Additional questions addressed consequences of policy violation, the use of cell phones for curricular activities and principals’ attitudes toward cell phone policies. (more…)
Author Interviews, Cannabis, CDC, JAMA, Pediatrics, Tobacco Research / 18.05.2020

MedicalResearch.com Interview with: Susan Hocevar Adkins, MD Lead Author, Senior Medical Officer, and Commander United States Public Health Service CDC MedicalResearch.com: What is the background for this study? Response: Since August 2019, the Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA), and state, local, and territorial health departments have been investigating a national outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). Although clinical presentation and outcomes of EVALI patients generally have been reported, data on adolescent patients are more limited. This article fills this gap by using data from national EVALI surveillance at CDC to examine demographic, substance use, and clinical characteristics of adolescent EVALI patients relative to young adult and adult EVALI patients.

Author Interviews, JAMA, Surgical Research, Weight Research / 16.05.2020

MedicalResearch.com Interview with: Wei Bao, MD, PhD Assistant Professor Department of Epidemiology, College of Public Health, University of Iowa, Iowa City, IA 52242 and Dr. Yangbo Sun, PhD (Former postdoc research scholar at University of Iowa) Tenure-track Assistant Professor The University of Tennessee Health Science Center.   MedicalResearch.com: What is the background for this study? Response: Obesity is a rising epidemic in the United States and worldwide. Bariatric surgery has been shown to be the most effective and durable treatment for clinically morbid obesity which is difficult to reverse through traditional approaches such as lifestyle intervention. There has been long-standing uncertainty and debate regarding the value of pre-operative weight loss as a requirement for bariatric surgery. Meanwhile, one of the major indicators for surgery outcomes is 30-day mortality after surgery, which is especially important for bariatric surgery because the vast majority of the patients undergoing bariatric surgery are voluntary and if the surgery were not performed, they are not supposed to die in short term. So far, the association of pre-operative weight loss with 30-day mortality after bariatric surgery remains unclear. Therefore, in this study, we examined the associations of pre-operative BMI and weight loss with 30-day mortality following bariatric surgery using a large database among ~500,000 patients who underwent bariatric surgery in the United States and Canada.
