Author Interviews, JAMA, OBGYNE, Pediatrics, Social Issues / 15.07.2019

MedicalResearch.com Interview with: Dr. Marina Mendonca PhD RECAP project (Research on European Children and Adults Born Preterm) Department of Psychology University of Warwick, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research on the social lives of adults born preterm (under 37 weeks gestation) was inconsistent. This meta-analysis brought together data from up to 4.4m adult participants and has shown that those who were born preterm are less likely to form romantic relationships, to have had sexual relations or experience parenthood than full terms. For example, those born preterm were 28% less likely to form romantic relationships and 22% less likely to become parents, when compared to those born full term. When looking at sexual relations, preterm born adults were 2.3 times (or 57%) less likely to ever have a sexual partner. These associations were found for both men and women, and were stronger the lower gestational age. This means that the chances of finding a romantic partner or having children were lower for those born very (<28 weeks gestation) or extremely preterm (<28 weeks gestation), with the extremely pre-term born adults being for example 3.2 times (78%) less likely to ever having had sexual relations when compared to their full term peers. Despite having fewer relationships, we found that when adults who were born preterm had friends or a partner, the quality of these relationships was at least as good as those born full term.  (more…)
Author Interviews, Genetic Research, Heart Disease, Imperial College, JAMA / 12.07.2019

MedicalResearch.com Interview with: Ben Cordon, PhD NIHR Post-doctoral Academic Clinical Fellow Specialist Registrar training in cardiology  James S. Ware, PhD, MRCP  Reader in Genomic Medicine Group head within the Cardiovascular Genetics & Genomics Unit Imperial College London     MedicalResearch.com: What is the background for this study?   Response: Non-ischaemic dilated cardiomyopathy is a common cause of heart failure and carries the risk of life-threatening ventricular arrhythmia. An implantable cardioverter defibrillator (ICD) can be life-saving in this condition. However, the decision to implant an ICD is not one that can be taken lightly - ICD insertion carries its own risks, such as infection or inappropriate shocks, and our ability to predict who will benefit from a device is currently far from perfect. Genetic sequencing is affordable and widely available and for DCM, like many diseases, it is hoped that genetic stratification may one day help deliver personalised management. In DCM, variants in the Lamin A/C gene for example are known to cause a phenotype with early and severe arrhythmias and, as a result, international guidelines advocate a lower threshold for ICD insertion in these patients. However, Lamin A/C is an infrequent cause of DCM. The commonest known genetic cause of DCM are protein-truncating variants in the gene encoding Titin (TTNtv), accounting for ~15% of DCM cases. We wanted to know if this group had a higher risk of arrhythmia than the general DCM population. Earlier work from our group on this topic found that patients with TTNtv-associated DCM were more likely to have a clinical history of arrhythmia (composite of atrial and ventricular arrhythmia, including NSVT), at the time of their initial DCM diagnosis. But it was unclear if this was driven by ventricular arrhythmia, atrial arrhythmia, or both or if it would translate into a long-term risk of potentially dangerous ventricular arrhythmia of the sort for which an ICD can be life-saving. In another study we analysed a larger cohort of ambulant DCM patients but did not find an increased risk of ventricular arrhythmia – but this was a relatively low-risk group, with comparatively mild symptoms (NHYA I/II heart failure) and moderately impaired LV function. As a result, the overall arrhythmic event rate was low, meaning that the power to detect differences between the TTNtv and non-TTNtv groups was reduced. (more…)
Author Interviews, Blood Pressure - Hypertension, Heart Disease, JAMA / 12.07.2019

MedicalResearch.com Interview with: Dr Kazem Rahimi Deputy Director of the George Centre for Healthcare Innovation James Martin Senior Fellow in Essential Healthcare Honorary Consultant Cardiologist at the John Radcliffe Hospital Deputy Director of the George Institute for Global Health MedicalResearch.com: What is the background for this study? Response: In the last century, we have witnessed a dramatic change in the spectrum of valvular heart disease and the prevalence of this condition has been rapidly increasing, due to population ageing, with poor patient outcomes and high healthcare costs associated with the only effective treatment available, which is valve repair or replacement. However, modifiable risk factors for valvular heart disease remain largely unknown, which limits prevention and treatment. We used a state-of-the-art, gene-based method called Mendelian randomization to determine the causality of the association between systolic blood pressure and risk of valvular heart diseases.  (more…)
Anemia, Author Interviews, Heart Disease, JAMA, Karolinski Institute / 11.07.2019

MedicalResearch.com Interview with: Dr. Niels Grote Beverborg, MD PhD Post-doctoral research fellow Department of experimental cardiology University Medical Center Groningen, Groningen, The Netherlands Integrated CardioMetabolic Center Karolinska Institutet, Stockholm Sweden  MedicalResearch.com: What is the background for this study?   Response: Iron deficiency is very prevalent worldwide and a significant cause of morbidity and mortality, especially in vulnerable populations such as patients with heart failure. It is well known that iron deficiency can be a consequence of an insufficient iron uptake or increased iron loss (termed low iron storage), or of a chronic low inflammatory state (defective iron utilization). However, so far, we had no tools to distinguish these causes from each other in patients and have not been able to assess their potential consequences. (more…)
Author Interviews, JAMA, Nutrition, Weight Research / 11.07.2019

MedicalResearch.com Interview with: Anne Thorndike, MD, MPH Massachusetts General Hospital General Internal Medicine Division Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: Nearly one-third of the 150 million US adults who are employed are obese. Employees frequently eat meals acquired at work, and workplace food is often high in calories. Effective strategies for reducing non-nutritive energy intake during the workday could help address the rising prevalence of obesity. Simplified labeling, such as traffic-light labels, provide understandable information about the relative healthfulness of food and can be placed on menu boards, shelf labels, and individual packages to help employees make healthier choices. Choice architecture (e.g., product placement) interventions make it easier and more convenient for employees to choose a healthy item. It is unknown if labeling interventions are associated with sustained reductions in calorie intake, or if there are only temporary effects after which most people revert to higher-calorie choices. A previous study demonstrated that a hospital cafeteria traffic-light labeling and choice architecture program resulted in a higher proportion of healthy green-labeled purchases and lower proportion of unhealthy red-labeled purchases over two years. The current study analyzed calories purchased by a longitudinal cohort of 5,695 hospital employees who used the cafeteria regularly. The study examined changes in calories purchased over time and hypothesized the effect of the change in calorie intake on employees’ weight. (more…)

MedicalResearch.com Interview with: video-gamesDr. Klaus Wölfling Psychologische Leitung - Ambulanz für Spielsucht Klinik und Poliklinik für Psychosomatische Medizin und Psychotherapie Universitätsmedizin der Johannes Gutenberg-Universität Mainz Mainz MedicalResearch.com: What is the background for this study? What are the main findings?  Response:  Our institution, the outpatient clinic of Behavioral Addictions at the Department of Psychosomatic Medicine, University Medical Center Mainz started as a pilot project, which was funded by Rhineland-Palatine, our federal state in Germany. We rapidly noticed the need for treatment in the population. We revealed insights of the disease during the last decade. During this time, we developed and refined therapeutic processes addressing Internet Addiction and Gaming Disorder. We conducted a pilot study, which tested the feasibility of a CBT-treatment approach for Internet Addiction in an RCT. We learned a lot from therapy research and noticed that it was important to conduct a study, which indicates an effective treatment for this disease. STICA found a strong remission rate for Internet and Computer game Addiction of treatment group vs. WLC (OR=10.10; 94% CI 3.69 to 27.65). (more…)
Author Interviews, Dermatology, Gastrointestinal Disease, JAMA / 11.07.2019

MedicalResearch.com Interview with: Prof Ching-Chi Chi, MD, MMS, DPhil (Oxford) Department of Dermatology Chang Gung Memorial Hospital, Linkou Guishan Dist, Taoyuan 33305 Taiwan MedicalResearch.com: What is the background for this study? Response: Hidradenitis suppurativa (HS) and inflammatory bowel disease (IBD) are inflammatory diseases that share common clinical manifestations, genetic susceptibility, and immunologic features. For example, both diseases have similar clinical manifestations in the skin and gut, characterized by sterile abscesses in perineal and inguinal areas, scarring, and sinus tract formation. Both diseases have been associated with an increased prevalence of spondyloarthropathy, have common risk factors (smoking and obesity), and respond well to tumor necrosis factor-inhibitors. Some studies have suggested a link between HS and IBD, but data on the association of HS and IBD remain inconsistent and unclear. Therefore, we conducted a meta-analysis to investigate the association of hidradenitis suppurativ with IBD. (more…)

MedicalResearch.com Interview with: D. Mark Anderson, Ph.D. Associate Professor Department of Agricultural Economics and Economics Montana State University, IZA, and NBER MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Using data from the Youth Risk Behavior Surveys for the period 1993-2017, we explore the effect medical and recreational marijuana laws have on teen use. We find that medical marijuana laws (MMLs) are not associated with teen marijuana consumption, but recreational marijuana laws (RMLs) are actually negatively associated with teen use.  (more…)

MedicalResearch.com Interview with: Dr. Ann M. O’Hare, MD Professor,Division of Nephrology University of Washington Investigator, VA HSR&D Center of Excellence Affiliate Investigator, Group Health Research Institute Seattle, WA  MedicalResearch.com: What is the background for this study? Response: We know that survival for people undergoing dialysis is generally quite limited.  Only a few studies have attempted to elicit how patients undergoing dialysis understand prognosis and how their prognostic awareness might be related to their interest in planning for the future, their preferences for resuscitation and the kind of care they would want if they were seriously ill or dying.

Aging, Author Interviews, Cognitive Issues, Gender Differences, Hormone Therapy, JAMA, Menopause, Weight Research / 05.07.2019

MedicalResearch.com Interview with: Rachel Zsido PhD student Department of Neurology International Max Planck MedicalResearch.com: What is the background for this study? Response: We integrated measures of brain network structure, visceral adipose tissue (VAT), serum estradiol levels, and cognitive performance from 974 participants in order to shed light on potential mechanisms underlying cognitive health. We believe it is imperative to assess sex-specific risk trajectories in brain aging and cognitive decline, especially given the known sex differences in both VAT accumulation patterns and estradiol fluctuations across the lifespan. Thus, we aimed to answer three questions in men and in women: 1) Does visceral adipose tissue exacerbate the association between age and brain network structure, 2) Does estradiol mitigate the negative association between VAT and brain network structure, and 3) What does this imply for healthy cognitive aging in men and women?  (more…)
Author Interviews, JAMA / 04.07.2019

MedicalResearch.com Interview with: Lucy Schulson, MD MPH Section of General Internal Medicine Boston University School of Medicine Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: Research in the early 2000s in California demonstrated that racial and ethnic minorities, immigrants, and those with limited English proficiency (LEP) experienced high rates of discrimination in healthcare. Since those studies were published, California has made concerted efforts at the state and local level to address health equity; these efforts may have impacted perceptions of discrimination in health care. However, it is not known how perceptions of discrimination in healthcare have changed over the last ten years overall and for specific groups. This study sought to compare perceptions of discrimination in health care in 2003-2005 compared to 2015-2017 overall, for racial and ethnic minorities, among immigrants, and among those with Limited English Proficiency (LEP).  (more…)
Author Interviews, Cancer Research, JAMA / 03.07.2019

MedicalResearch.com Interview with: Farhad Islami, MD PhD Scientific Director, Surveillance Research American Cancer Society, Inc MedicalResearch.com: What is the background for this study?   Response: In the United States, cancer is the second leading cause of death, and premature cancer deaths impose significant economic burden. Contemporary information on the economic burden of cancer mortality can inform policies and help prioritize resources for cancer prevention and control, but this information is lacking. In our study, we provide contemporary estimates for the loss of future earnings (lost earnings) due to cancer death at national and state levels for all cancers combined and for major cancers.

Author Interviews, CDC, Emory, Infections, JAMA, Pediatrics, Vaccine Studies / 02.07.2019

MedicalResearch.com Interview with: Ms. Cassandra Pingali Ms. Pingali worked on this paper while a a graduate student at Emory University, and completed it post-graduation. She is currently an ORISE fellow at Centers for Disease Control and Prevention Immunization Services Division MedicalResearch.com: What is the background for this study? Response: Despite high overall immunization coverage in the United States, we are currently experiencing the largest measles outbreak since measles was declared eliminated in 2000. In 2014, California grappled with a very large measles outbreak known as the “Disneyland” outbreak. Later investigation revealed that most of the affected children were unvaccinated against measles despite the availability of a safe and effective vaccine. In order to prevent future outbreaks, California officials wanted to improve their declining childhood vaccination coverage. California passed two laws and implemented an educational program for school staff to increase vaccination rates in the state. We felt it was important to take a systematic look at these interventions and examine if public health initiatives such as these are working to improve vaccination rates. (more…)
Addiction, Author Interviews, JAMA, Opiods, University of Michigan / 30.06.2019

MedicalResearch.com Interview with: Rebecca L. Haffajee, J.D., Ph.D., M.P.H. Assistant Professor Department of Health Management & Policy umichsphumichsph MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Evidence suggests that the availability of medications to treat opioid use disorder (OUD) has been slow to expand, particularly in rural areas, despite the efficacy and effectiveness of these medications in reducing overdose deaths and other adverse life outcomes. We were interested in understanding the characteristics of counties both with high need (as measured by above-national rates in opioid overdose deaths) AND low provider capacity to deliver medications to treat OUD in 2017. We found that such "opioid high-risk" counties were likely to be in the East North Central (e.g., Michigan, Ohio, Illinois, Indiana), South Atlantic (e.g., North Carolina, South Carolina, Virginia, West Virginia), and Mountain (e.g., New Mexico, Arizona, Nevada) regions. We also found that these opioid high-risk counties were more likely to have higher rates of unemployment and less likely to have fewer primary care clinicians or be micropolitan (more…)
Author Interviews, Columbia, JAMA, Pulmonary Disease / 28.06.2019

MedicalResearch.com Interview with: Elizabeth C. Oelsner, MD, MPH Irving Assistant Professor of Medicine Division of General Medicine New York Presbyterian Columbia University MedicalResearch.com: What is the background for this study? Response: Uncertainty regarding how to diagnose chronic obstructive pulmonary disease (COPD) has posed significant problems for early detection and treatment of this common disease. Simplifying and standardizing the diagnosis of COPD has the potential to improve diagnosis, clinical care, and clinical research for this common and under-diagnosed chronic lung disease. We therefore aimed to provide robust evidence for the best threshold to diagnose COPD by comparing how well various thresholds predict hospitalizations and deaths from COPD. (more…)
Author Interviews, JAMA, Pediatrics, Sexual Health, Technology / 28.06.2019

MedicalResearch.com Interview with: texting, sextingCamille Mori, B.A. (hons) M.Sc. candidate Clinical Psychology Program Determinants of Child Development Lab University of Calgary  MedicalResearch.com: What is the background for this study? Response: Sexting, which is the sharing of sexual messages, images, or videos over technological devices, has recently become a cause for concern among parents, teachers, and policy makers. However, the research on sexting among youth is still in early stages, and evidence of the risks associated with sexting is inconsistent. One way to resolve discrepancies in the field is to conduct a meta-analysis, which statistically summarizes existing research. We conducted a meta-analysis in order to examine the association between sexting and sexual activity (having sex, multiple sexual partners, and lack of contraception use). The associations between sexting and mental health related variables, including delinquent behaviour, substance use, and depression/anxiety were also examined. (more…)
ALS, Alzheimer's - Dementia, Author Interviews, Biomarkers, JAMA, Multiple Sclerosis / 27.06.2019

MedicalResearch.com Interview with: Charlotte E. Teunissen, PhD Neurochemistry Laboratory, Department of Clinical Chemistry VU University Medical Centre, Neuroscience Campus Amsterdam Amsterdam, the Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several reports have shown increased in NfL in various neurological disorders, separately. We wanted to know how the levels are in these disorders relative to each other. Moreover, some reports showed absence of age effects in Multiple Sclerosis (MS) patients, which is normally present in controls. So, we thought that it would be good to study age effects in a large group of controls, and if these effects are absent in other diseases, similarly as in MS. (more…)
Author Interviews, JAMA, Prostate, Prostate Cancer, Urology / 25.06.2019

MedicalResearch.com Interview with: Kari Tikkinen, MD, PhD, Adjunct Professor Departments of Urology and Public Health University of Helsinki and Helsinki University Hospital Helsinki, Finland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Men’s choice of whether to undergo screening is value and preference sensitive: fully informed men will make different choices depending on their experience and perspective. For such decisions, shared decision-making represents an ideal approach to decision making. In shared decision-making both the patient and health care provider contribute to the medical decision-making process. The health care provider explains alternatives to patients, informs them of the best evidence regarding the anticipated consequences of a decision for or against the intervention, and helps them choose the option that best aligns with their preferences. All major guidelines of prostate cancer screening acknowledge the importance of informing men about risks and benefits of PSA screening. Shared decision-making is challenging because it requires time, knowledge, and specific skills. Prostate cancer screening decisions aids may, by summarizing the current best evidence and by supporting conversations that address what matters most to men, address these challenges. The impact of decision aids on the decision-making process is, however, uncertain. We therefore undertook a systematic review and meta-analysis of the randomized trials that have addressed the impact of decision aids in the context of prostate cancer screening.  (more…)
Amgen, Author Interviews, Cost of Health Care, JAMA, Lipids, UCLA / 24.06.2019

MedicalResearch.com Interview with: Gregg C. Fonarow, MD, FACC, FAHA Eliot Corday Professor of Cardiovascular Medicine and Science Director, Ahmanson-UCLA Cardiomyopathy Center Co-Chief of Clinical Cardiology, UCLA Division of Cardiology Co-Director, UCLA Preventative Cardiology Program David Geffen School of Medicine at UCLA Los Angeles, CA  MedicalResearch.com: What is the background for this study? Response: Last year, Amgen made the PCSK-9 inhibitor evolocumab available at a reduced list price of $5,850 per year This 60% reduction was aimed at improving patient access by lowering patient copays, especially for Medicare beneficiaries. Additionally, the treatment landscape for PCSK9 inhibitors was further defined in 2018 when the American College of Cardiology/American Heart Association Multisociety Clinical Guideline on the Management of Blood Cholesterol recommended PCSK9 inhibitors for, among other patient populations, patients with very high-risk (VHR) ASCVD whose low-density lipoprotein cholesterol levels remain at 70 mg/dL or more  despite a heart-healthy lifestyle and treatment with standard background therapy.

MedicalResearch.com Interview with: Liping Pan, MD, MPH Epidemiologist Division of Nutrition, Physical Activity, and Obesity National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Children with severe obesity face significant health and social challenges. Children with obesity are at higher risk for having other chronic health conditions and diseases, such as asthma, sleep apnea, bone and joint problems, and type 2 diabetes. They also have more risk factors for heart disease such as high blood pressure, impaired glucose tolerance, and high cholesterol than their healthyweight peers. Children with obesity can be bullied and teased more than their healthyweight peers. They are also more likely to suffer from social isolation, depression, and lower self-esteem. Children with obesity are also more likely to have obesity as adults. This can lead to lifelong physical and mental health problems. Adult obesity is associated with a higher risk of type 2 diabetes, heart disease, and many types of cancers.  Childhood obesity is more common among children from lower-income families, as many lack access to healthy, affordable foods and beverages and opportunities for low-cost physical activity.

Author Interviews, Geriatrics, JAMA, Ophthalmology, University of Michigan / 21.06.2019

MedicalResearch.com Interview with: Joshua R. Ehrlich, MD, MPH Assistant Professor, Ophthalmology and Visual Sciences Kellogg Eye Center Department of Ophthalmology and Visual Sciences University of Michigan  MedicalResearch.com: What is the background for this study?   Response: This study came out of data collected as part of the National Poll on Healthy Aging (NPHA). The NPHA is funded by AARP and the Institute for Healthcare Policy and Innovation at the University of Michigan to inform the public, healthcare providers, and policymakers on a variety issues related to health. The vision survey, conducted in March 2018, was just one of many NPHA surveys. Due to aging of the population, the number of older U.S. adults with blindness and vision impairment is expected to double over the next 30 years. Thus, this study was designed to provide crucial data  on contemporary data on patterns of eye care utilization in older adults. (more…)

MedicalResearch.com Interview with: Changchuan (Charles) Jiang MD, MPH MSSLW Internal Medicine Residency Program Class of 2020 Ichan School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: Chronic pain is one of the common side effects of cancer treatments and it has been linked to low life quality, lower adherence to treatment, higher medical cost. As the population of cancer survivors grows rapidly, chronic pain will be a major public health issue in this population. We know from previous studies that chronic pain is common in certain cancers such as breast cancer. However, little was known about the epidemiology of chronic pain in the cancer survivors until our study. (more…)

MedicalResearch.com Interview with: Christian Krautz, MD Department of Surgery, Universitätsklinikum Erlangen Friedrich-Alexander-Universität Erlangen Nürnberg Erlangen, Germany  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this preclinical study that included 720 case evaluations, visualization with Cinematic Rendering allowed a more correct and faster comprehension of the surgical anatomy compared to conventional CT imaging independent from the level of surgical experience. Therefore,Cinematic Rendering is a tool that may assist HPB surgeons with preoperative preparation and intraoperative guidance through an improved interpretation of computed tomography imaging data.

Author Interviews, Geriatrics, Hip Fractures, JAMA, Orthopedics, Osteoporosis / 17.06.2019

MedicalResearch.com Interview with: Kristine E. Ensrud MD MPH Professor of Medicine and Epidemiology and Community Health University of Minnesota Core Investigator, Center for Care Delivery and Outcomes Research Minneapolis VA Health Care System  MedicalResearch.com: What is the background for this study? Response: Women aged 80 years and older, a rapidly growing segment of the population, account for the majority of hip fractures in the United States. Hip fractures account for 72% of fracture-related health care expenditures and lead to significant morbidity and mortality. However, many late-life women at high risk of hip fracture are undiagnosed. Clinicians have difficulty identifying late-life women most likely to benefit from osteoporosis screening and interventions to prevent hip fracture in part due to concerns about comorbidity burden and prognosis in this patient population.

MedicalResearch.com Interview with: Quinn R Pack, MD Assistant Professor of Medicine University of Massachusetts Medical School - Baystate Adjunct Assistant Professor of Medicine Tufts University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Because echocardiograms are non-invasive, very low risk, and nearly universally available, it is easy to over-use this technique.  In myocardial infarction, echo is also recommended in guidelines. However, in our lab, we frequently find echocardiograms that are ordered purely out of routine, without any thought as to the likelihood of finding an abnormality.   Prior studies also suggested that as many as 70% of echocardiograms provide no additional diagnostic value. When spread across the approximate 600,000 patients in the United States each year, this low diagnostic yield represents an opportunity to reduce costs by reducing echocardiograms.  (more…)
