Author Interviews, Infections, JAMA, Mental Health Research, Pediatrics / 25.04.2019

MedicalResearch.com Interview with: Lauren Breithaupt, PhD Department of Psychology George Mason University Fairfax, Virginia  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Our study provides novel insight into the relationship between the immune system and eating disorders characterized by chronic restriction (e.g., anorexia nervosa) and binge eating and/or purging (e.g., binge eating disorder, bulimia nervosa). These findings also add to the growing body of literature linking the immune systems broadly and mental disorders. We found that infections in early childhood were associated with an increased risk of anorexia nervosa, bulimia nervosa, and other eating disorders such as binge eating disorder in adolescence. These relationships appear to be both time and dose-dependent, meaning that the onset of eating disorder diagnosis is greatest in the first three months following the infection, and the more infections, the greater the risk.    (more…)
Author Interviews, Genetic Research, Heart Disease, JAMA, Lipids / 25.04.2019

MedicalResearch.com Interview with: Florian Kronenberg, MD Division of Genetic Epidemiology Department of Medical Genetics, Molecular and Clinical Pharmacology Medical University of Innsbruck, Innsbruck, Austria MedicalResearch.com: What is the background for this study? Response: Lp(a) is one of the most prevalent lipoprotein risk factors for cardiovascular disease. Roughly 20% of the general Caucasian population have concentrations above 50 mg/dL and the 10% with the highest concentrations have a 2 to 3-fold increased risk for myocardial infarction. There is strong evidence from genetic studies that high Lp(a) concentrations are causally related to cardiovascular outcomes. Until recently there was no drug available which lowers Lp(a) without any effects on other lipoproteins. This has recently changed by the development of drugs that block the production of Lp(a) in an impressive way. These drugs have to be studied in randomized controlled trials whether they not only lower Lp(a) concentrations but also cardiovascular outcomes. For the planning of such studies it is crucial to estimate the amount of Lp(a) lowering required to show a clinical benefit. (more…)
Author Interviews, JAMA, OBGYNE, Pediatrics, Race/Ethnic Diversity / 24.04.2019

MedicalResearch.com Interview with: Clare Brown, PhD Health Systems and Services Research University of Arkansas for Medical Sciences J. Mick Tilford, PhD, Professor and Chair Department of Health Policy and Management Fay W. Boozman College of Public Health University of Arkansas for Medical Science   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Prematurity and low birthweight are associated with increased risk of infant mortality as well as increased risk of chronic conditions throughout infancy and into adulthood. Non-Hispanic black infants are twice as likely to be born low birthweight (13.9% vs 7.0%) and 1.5 times as likely to be born prematurely (13.9% vs 9.1%) compared to non-Hispanic white infants. Under the Affordable Care Act (ACA), states may expand Medicaid to adults with household income levels at or below 138% of the federal poverty level, thus extending coverage to childless adults and improving continuity. Insurance gain may ultimately improve maternal health, increased use and earlier initiation of prenatal care services, and improved access to pregnancy planning resources. Our study aimed to evaluate whether there were changes in rates of low birthweight and preterm birth outcomes among states that expanded Medicaid versus states that did not expand Medicaid. (more…)
Author Interviews, Environmental Risks, JAMA, Pediatrics, Primary Care, Toxin Research, USPSTF / 23.04.2019

MedicalResearch.com Interview with: Alex H. Krist, MD, MPH Vice-Chairperson, U.S. Preventive Services Task Force Professor of family medicine and population healt Virginia Commonwealth University  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Exposure to lead can have serious lifelong effects on the health and wellbeing of children. There is no safe level of lead exposure, so finding and removing any source of lead exposure is essential. In its review of the evidence, the Task Force found that more research is needed to determine what primary care clinicians can do to help prevent and treat the health problems that can result from lead exposure in childhood and pregnancy.

Author Interviews, Environmental Risks, JAMA, Lymphoma, Occupational Health, Toxin Research / 23.04.2019

MedicalResearch.com interview with: Sylvain Lamure, MD, Hematologist, Principal Investigator Pascale Fabbro-Peray, MD, PhD , Epidemiologist, Senior Investigator University of Montpellier, France MedicalResearch.com: What is the background for this study? Response: Occupational exposure to pesticides is a well-documented associated factor for non-Hodgkin lymphoma. The main biological mechanisms of both pesticides and chemotherapy are genotoxicity and reactive oxygen species generation. Cellular adaptation among patients exposed to low doses of genotoxic and oxidative compounds might hinder chemotherapy efficiency in lymphoma patients. T hus, we have investigated the association of occupational exposure with response to immunochemotherapy and survival in the subgroup of diffuse large B cell lymphoma, whose treatment is standardized.

Author Interviews, JAMA, Pediatrics, Sugar / 23.04.2019

MedicalResearch.com Interview with: Asher Y Rosinger, PhD, MPH Assistant Professor of Biobehavioral Health and Anthropology Director of the Water, Health, and Nutrition Laboratory Pennsylvania State University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sugar-sweetened beverage consumption has been linked to many negative health conditions, such as weight gain, dental caries, and type 2 diabetes. Previous research found that when you replace sugar-sweetened beverages (SSBs) with water intake then total energy intake goes down. We wanted to know how many calories from SSBs children consume when they drink water or not since sugar-sweetened beverages are often used as a replacement for water. SSB intake has been falling among children over the last 15 years, but there are still pockets and sub-populations that have high consumption levels. It is critical to identify which kids are particularly at risk for high SSB intake since this can lead to these negative health effects. Overall we found that kids that did not consume any plain water (from tap or bottled water) consumed almost twice as many calories and percent of total calories from sugar-sweetened beverages than kids that consumed water. And for the sample overall that translated to nearly 100 extra calories on a given day.  (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, JAMA, Radiation Therapy, Technology / 19.04.2019

MedicalResearch.com Interview with: Raymond H Mak, MD Radiation Oncology Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? 
  • Lung cancer remains the most common cancer, and leading cause of cancer mortality, in the world and ~40-50% of lung cancer patients will need radiation therapy as part of their care
  • The accuracy and precision of lung tumor targeting by radiation oncologists can directly impact outcomes, since this key targeting task is critical for successful therapeutic radiation delivery.
  • An incorrectly delineated tumor may lead to inadequate dose at tumor margins during radiation therapy, which in turn decreases the likelihood of tumor control.
  • Multiple studies have shown significant inter-observer variation in tumor target design, even among expert radiation oncologists
  • Expertise in targeting lung tumors for radiation therapy may not be available to under-resourced health care settings
  • Some more information on the problem of lung cancer and the radiation therapy targeting task here:https://www.youtube.com/watch?v=An-YDBjFDV8&feature=youtu.be

MedicalResearch.com Interview with: Robert C. Miller, MD, MS, MBA Department of Radiation Oncology, Mayo Clinic, Jacksonville, Florida University of Maryland School of Medicine, Baltimore MedicalResearch.com: What is the background for this study? What are the main findings? Response: "Magic Mouthwash" is one of the most commonly prescribed medications for oral mucositis pain during cancer therapy, but there has not been good evidence in the past to support its use. This trial is the first large randomized controlled trial to demonstrate that both "Magic" mouthwash and doxepin rinse reduce patient reported pain during cancer therapy. (more…)
Author Interviews, Depression, Genetic Research, JAMA / 19.04.2019

MedicalResearch.com Interview with: Dr Kimberley Kendall MBBCh Wellcome Trust Clinical Research Fellow Professor James Walters MRC Centre for Neuropsychiatric Genetics and Genomics Professor, Division of Psychological Medicine and Clinical Neurosciences Cardiff University   MedicalResearch.com: What is the background for this study? Response: Copy number variants (CNVs) are the deletion or duplication of large sections of DNA. Large, rare CNVs have been shown to increase the risk of neurodevelopmental disorders including autism spectrum disorder (ASD), intellectual disability (ID), attention deficit/hyperactivity disorder (ADHD) and schizophrenia. However, the impact of these CNVs on risk of depression was unclear from the existing literature. (more…)

MedicalResearch.com Interview with: Associate Professor Josip Car MD, PhD, DIC, MSc, FFPH, FRCP (Edin)​ Associate Professor of Health Services Outcomes Research,​ Director, Health Services Outcomes Research Programme and Director Centre for Population Health Sciences Principal Investigator, Population Health & Living Laboratory  MedicalResearch.com: What is the background for this study? Response: In 2018, almost 8% of people with diabetes who owned a smartphone used a diabetes app to support self-management. Currently, most apps are not regulated by the US Food and Drug Administration (FDA). We downloaded and assessed 371 diabetes self-management apps, to see if they provided evidence-based decision support and patient education.  (more…)
Author Interviews, Education, JAMA, University of Pennsylvania / 16.04.2019

MedicalResearch.com Interview with: Krisda Chaiyachati, MD, MPH, MSHP Assistant Professor Medicine, Perelman School of Medicine Clinical Innovation Manager Penn's Center for Health Care Innovation Perelman School of Medicine Medical Director, Penn Medicine's FirstCall Virtual Care   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The United States spends more than $12 billion annually on training young doctors who have rates of burnout and depression at an alarmingly high rate. Yet, we have limited evidence as to what they are doing while training in the hospital. We sought to glimpse into how their day is spent. In the largest study to date, we observed 80 first-year internal medicine physicians (“interns”) for nearly 2200 hours across 194 work shifts at 6 different sites. Our research sought to understand what medical residents did by categorizing training activities into themes such as time spent in education or patient care.  (more…)
Author Interviews, Cost of Health Care, Hospital Readmissions, JAMA, Outcomes & Safety / 16.04.2019

MedicalResearch.com Interview with: Karen Joynt Maddox, MD, MPH Assistant Professor of Medicine Washington University Brown School of Social Work  MedicalResearch.com: What is the background for this study? Response: Medicare’s Hospital Readmissions Reduction Program has been controversial, in part because until 2019 it did not take social risk into account when judging hospitals’ performance. In the 21st Century Cures Act, Congress required that CMS change the program to judge hospitals only against other hospitals in their “peer group” based on the proportion of their patients who are poor. As a result, starting with fiscal year 2019, the HRRP divides hospitals into five peer groups and then assesses performance and assigns penalties.  (more…)
Author Interviews, Brigham & Women's - Harvard, Gender Differences, JAMA, Surgical Research / 16.04.2019

MedicalResearch.com Interview with: Nelya Melnitchouk, MD,MSc Director, Program in Peritoneal Surface Malignancy, HIPEC Dr. Melnitchouk is an associate surgeon at Brigham and Women’s Hospital (BWH) and Brigham and Women’s Faulkner Hospital (BWFH) and instructor of surgery at Harvard Medical School. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current literature on women in surgery show that female physicians, particularly those in procedural specialties, face many challenges in balancing responsibilities between work and home. We hypothesized that these challenges may affect career satisfaction more negatively for physician mothers in procedural specialties than those in nonprocedural specialties. In our study, we found that physician mothers in procedural specialties who had more domestic responsibilities were more likely to report a desire to change careers than those in nonprocedural specialties.  (more…)
Author Interviews, JAMA, University of Pennsylvania / 14.04.2019

MedicalResearch.com Interview with: Genevieve P. Kanter, PhD Assistant Professor (Research) of Medicine Medical Ethics and Health Policy University of Pennsylvania Perelman School of Medicine Philadelphia, PA  19104-6021 MedicalResearch.com: What is the background for this study?   Response: Physicians frequently have financial relationships with pharmaceutical and medical device firms, but only recently has information on these financial ties been made available to the public. The Open Payments program, created by the Physician Payment Sunshine Act, has made this industry payments information available through a public website since 2014. Because transparent institutions are believed to engender greater public trust, public disclosure of industry payments could increase public trust in the medical profession, which may have been weakened by physicians' relationships with industry. On the other hand, Open Payments may have decreased public trust because of the focus of media reporting on physicians receiving the largest sums of money. We sought to investigate how Open Payments and the public disclosure of industry payments affected public trust in physicians and in the medical profession. We compared changes in trust among patients who lived in states where payments information had, by state statute, previously been made available, to changes in trust among patients who lived in states where this information became newly available through Open Payments.

Author Interviews, Exercise - Fitness, Gender Differences, Heart Disease, JAMA, Johns Hopkins, Women's Heart Health / 14.04.2019

MedicalResearch.com Interview with: Erin D. Michos, MD, MHS, FACC, FAHA, FASE Associate Professor of Medicine and Epidemiology Associate Director of Preventive Cardiology Ciccarone Center for the Prevention of Heart Disease Johns Hopkins School of Medicine Victor Okunrintemi, MD, MPH Department of Internal Medicine East Carolina University Greenville, North Carolina  MedicalResearch.com: What is the background for this study?   Response: Women are less physically active than men on average, and the lack of regular physical activity has been associated with increased risk of cardiovascular disease and poorer health outcomes. Although recommendations encouraging regular physical activity has been in place for decades, we do not know how much of these recommendations are met, particularly among high risk women with established cardiovascular disease for secondary prevention. This study was therefore designed with the aim of describing the 10-year trends for the proportion of women with cardiovascular disease who do not meet these recommend physical activity levels, overall and by key sociodemographic groups, and the associated cost implications.

Author Interviews, Emergency Care, Global Health, JAMA / 12.04.2019

MedicalResearch.com Interview with: Margaret B. Greenwood-Ericksen MD, MSc Department of Emergency Medicine University of New Mexico Albuquerque, NM 87109 MedicalResearch.com: What is the background for this study?   Response: I’m an emergency physician, so I see first-hand how emergency department use patterns provide a lens into the status of health care delivery in the communities they serve. Troubling declines in the health of rural Americans coupled with rising rural hospital closures – with little access to alternative sites of care like urgent care – all led me to hypothesize that rural populations may be engaging with the health care system differently than their urban counterparts. Understanding the health care use of individuals in rural areas may yield insights into addressing rural health disparities. Further, this information may help healthcare systems and policymakers to make data-driven decisions informing new models of healthcare delivery for rural communities. (more…)
Author Interviews, Cancer Research, Health Care Systems, JAMA, Outcomes & Safety, Surgical Research, Yale / 12.04.2019

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? What are the main findings? Response: Prominent cancer hospitals have been sharing their brands with smaller hospitals in the community.  We conducted a series of nationally representative surveys and found that a significant proportion of the U.S. public assumes that the safety of care is the same at all hospitals that share the same respected brand.  In an effort to determine if safety was in fact the same, we examined complex surgical procedures in the Medicare database. We compared the chance of dying within 90 days of surgery between top-ranked hospitals, and the affiliate hospitals that share their brands.  When taking into account differences in patient age, health, and type of procedure, Medicare patients were 1.4 times more likely to die after surgery at the affiliate hospitals, compared to those having surgery at the top-ranked cancer hospitals.

Author Interviews, Epilepsy, Genetic Research, JAMA, Pediatrics / 12.04.2019

MedicalResearch.com Interview with: Dr. Ahmad Abou Tayoun, PhD Clinical Molecular Geneticist Director of the Genetics Laboratory Al Jalila Children’s United Arab Emirates MedicalResearch.com: What is the background for this study?   Response: In this study, we provide data in favor of using an exome-based testing approach, where parental samples can be readily accessible, for early onset epilepsy patients. The exome test includes all coding genes in the human genome. Although we perform exome sequencing on those patients, we demonstrate that a first tier analysis should include targeted interpretation of ~100 genes strongly associated with the disease. This analysis provides diagnoses in ~11% of the patients. Follow up parental testing on a limited number of patients (n=15) that had inconclusive results, revealed de novo (new mutations) variant status, leading to upgrade to positive reports in 7 patients and adding ~5% to the overall diagnostic yield.

Author Interviews, Cancer Research, JAMA, UT Southwestern / 11.04.2019

MedicalResearch.com Interview with: Nina Niu Sanford, M.D. Assistant Professor UT Southwestern Department of Radiation Oncology Dallas TX 75390 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: There has been increasing interest in use of complementary and alternative medicine in the oncology population – both in terms of its potential efficacy and harms. The main finding of this study is that approximately 1/3 of cancer patients and survivors self-reported using complementary or alternative medicine over the past year, the most common being herbal supplements. Of these patients, approximately 1/3 did not disclose to their physicians that they were doing so. (more…)
Author Interviews, Depression, Exercise - Fitness, JAMA, Parkinson's / 10.04.2019

MedicalResearch.com Interview with: Dr. Jojo Kwok  R.N., BN(Hons), MPH, Ph.D. School of Nursing, Li Ka Shing Faculty of Medicine The University of Hong Kong MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Before the study, we knew that mind-body exercises such as yoga and stretching improves the physical health of patients with Parkinson’s disease (PD), however the benefits to their mental health was not known. This study concludes that mindfulness yoga alleviates psychological distress, improves spiritual well-being and quality of life, not to mention motor symptoms and mobility. When it comes to managing the stress and symptoms of Parkinson Disease, what is exciting, is that yoga has now been proven to be a better strategy than just stretching. Yoga draws together body, mind and spirit through mindful practice of 1) yoga posture, 2) breathing and 3) meditation. These form the three core components of our Mindfulness Yoga Program. Mindfulness is non-judgemental awareness of the present moment - of one’s physical sensations and thoughts, be they positive or negative. By adopting a mind-body approach, patients are much better positioned to reframe their illness journey than through physical training alone. By learning to relate non-judgmentally to their physical symptoms and emotions, they develop new coping skills that cultivate openness, acceptance and resilience to these symptoms. They feel better.  (more…)
Author Interviews, Cancer Research, JAMA, Vitamin D / 09.04.2019

MedicalResearch.com Interview with: Mitsuyoshi Urashima MD, PhD, MPH Professor of Molecular Epidemiology Jikei University School of Medicine Tokyo, JAPAN MedicalResearch.com: What is the background for this study?   Response: Serum levels of vitamin D, increase in response to exposure to sunlight, a vitamin D-rich diet, or vitamin D supplementation. In 1989, the risk of colon cancer was estimated to be 70% lower in people with serum vitamin D levels ≥ 20 ng/mL, compared with those < 20 ng/mL. In a cohort study, higher vitamin D levels were associated with lower total cancer incidence and lower total cancer mortality, particularly digestive system cancer mortality. However, because of the studies’ observational nature, whether lower levels of vitamin D is merely a precursor to relapse and death or causally related to shorter survival cannot be determined. To clarify this, a randomized, double-blind, placebo-controlled trial using vitamin D supplement was performed in patients with digestive tract cancer from esophagus to rectum; this is the first trial designed to evaluate the effect of vitamin D on survival of these patients.  (more…)

MedicalResearch.com Interview with: Sanjay Kulkarni, MD MHCM FACS Associate Professor of Surgery & Medicine Surgical Director – Kidney Transplant Program Medical Director – Center for Living Organ Donors Scientific Director – Yale Transplant Research New Haven, CT 06410 MedicalResearch.com: What is the background for this study? Response: The kidney allocation system changed in December of 2014. The aim of the new system was to increase transplant in patients who were highly sensitized (difficult matches based on reactive antibodies) and to improve access to underserved populations. (more…)
Author Interviews, End of Life Care, Health Care Systems, JAMA / 08.04.2019

MedicalResearch.com Interview with: Cindy L. Cain, PhD Assistant Professor Department of Sociology University of Alabama at Birmingham Birmingham, AL 35233   MedicalResearch.com: What is the background for this study? What are the main findings? Response: The End of Life Option Act permits terminally ill Californians to request a prescription for medications that would hasten death, providing they meet all requirements of the law and follow the steps outlined by their health care provider. However, the law also allows health care providers and organizations to opt out of participating. Until now, we did not know how common it was for entire health care organizations to opt out. In this study, we found that 61% of the surveyed hospitals prohibited physician participation in the End of Life Option Act. Thirty-nine percent of hospitals did allow participation in the law; these participating hospitals were less likely to be religiously affiliated and more likely to be nonprofit. (more…)
ADHD, Author Interviews, JAMA, OBGYNE, Pediatrics, Pharmacology / 08.04.2019

MedicalResearch.com Interview with: Dr. Angela Lupattelli, PhD School of Pharmacy University of Oslo MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Between 1-4% of pregnant women take at least once a benzodiazepine and/or a z-hypnotic medication during the course of gestation. These medications are generally used intermittently in pregnancy, mainly for treatment of anxiety disorders and sleeping problems, which are not uncommon conditions among pregnant women. However, data regarding the safety of benzodiazepine and/or a z-hypnotic in pregnancy on child longer-term development are sparse. For instance, studies on child motor skills are only available up to toddler age, and little is known in relation to other child developmental domains. So, there is an urgent need to better understand whether prenatal use of benzodiazepine and/or a z-hypnotic medication may pose detrimental longer-term child risks. (more…)
Author Interviews, JAMA, Kidney Disease / 08.04.2019

MedicalResearch.com Interview with: Matthew T James MD, PhD Assistant Professor University of Calgary  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The Acute Kidney Disease and Disorders (AKD) criteria from the KDIGO Acute Kidney Injury guidelines identified many patients who do not meet existing criteria for Chronic Kidney Disease or Acute Kidney Injury (AKI), and the majority of AKD events occured in the community rather than hospital setting. This study characterized the frequency and outcome for patients with AKD (without  AKI) as well as AKD with CKD from among over 1.1 million adults  residing in Alberta Canada who received  kidney function testing and were followed for up to 8 years.

Author Interviews, ENT, JAMA, Pain Research, Pediatrics, Surgical Research / 05.04.2019

MedicalResearch.com Interview with: Gillian R. Diercks, MD, MPH Instructor in Otolaryngology, Harvard Medical School Department of Otolaryngology Massachusetts Eye and Ear Infirmary Boston, Massachusetts  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pediatric tonsillectomy is a commonly performed procedure, representing the second most common ambulatory surgery performed on children in the United States, with over half a million children undergoing the surgery annually.  A major concern for surgeons, patients, and their families is the issue of postoperative pain control as pain can last up to 10-14 days after surgery, be quite severe, and result in readmission to the hospital or ED visits for medications and dehydration. In young children and children with sleep apnea we cannot safely administer narcotic pain medications at home.  This leaves limited options for pain control, including acetaminophen and ibuprofen.  However, there are concerns that ibuprofen could potentially increase bleeding risk after surgery because of its effects on platelet function in the blood.  At baseline, the risk of postoperative hemorrhage within the first two weeks after tonsillectomy is around 4.5%, with about 1-1.5% of children requiring a return to the operating room to control severe bleeding.  Our study set out to show that the risk of severe postoperative bleeding when ibuprofen is given for 9 days after tonsillectomy was not increased compared with the bleeding risk when acetaminophen was administered instead. Our study could not conclude that the risk of bleeding is no different when ibuprofen is used, and was suggestive that the bleeding risk may actually be higher. (more…)
Author Interviews, Diabetes, Genetic Research, JAMA, Mental Health Research, Schizophrenia / 03.04.2019

MedicalResearch.com Interview with: Prof Sabine Bahn MD PhD MRCPsych FRSB Cambridge Centre for Neuropsychiatric Research Jakub Tomasik, PhD Department of Chemical Engineering and Biotechnology University of Cambridge   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Schizophrenia patients are at increased risk of impaired glucose metabolism, yet the comorbidity between the two conditions cannot be fully explained by known risk factors such as obesity, smoking, stress or antipsychotic medication. Previous family and genome-wide studies have suggested that the co-occurrence between schizophrenia and impaired glucose metabolism might be due to shared genetic factors, as exemplified by increased risk of diabetes in first-degree relatives of schizophrenia patients, but the biological mechanisms underlying this association remain unknown. We examined the association between insulin resistance, schizophrenia polygenic risk and response to treatment in 58 drug-naive schizophrenia patients and 58 matched healthy individuals while controlling for a range of demographic (age, gender, body mass index), lifestyle (smoking, alcohol and cannabis use) and clinical (psychopathology scores, treatment drug) factors. We found that insulin resistance, a key feature contributing to the development of type 2 diabetes, significantly correlated with schizophrenia polygenic risk score in patients, with higher genetic risk of schizophrenia associated with increased insulin resistance. Furthermore, we found that patients with higher insulin resistance were more likely to switch medication during the first year of treatment, which implies lower clinical response.  (more…)
Allergies, Author Interviews, Dermatology, Heart Disease, JAMA / 03.04.2019

MedicalResearch.com Interview with: Amber Reck Atwater, M.D. Dermatology Residency Program Director Associate Professor of Dermatology Director, Contact Dermatitis Clinic Duke Dermatology  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We completed an evaluation of our Duke Dermatology patients who underwent patch testing for possible allergy to their cardiac devices - pacemakers and defibrillators. From March 1, 2012 to September 15, 2017 we saw 11 patients with suspected allergy to their devices.  Concern for allergy, skin eruption, skin symptoms, and concern for infection were common. 73% of patients had erythema at their implant scars; pruritus and pain were also noted.  Six of our patients had relevant reactions, and the most common allergies were metals, silicone and rubber accelerators.  (more…)
Author Interviews, Cost of Health Care, General Medicine, Hospital Readmissions, JAMA, Race/Ethnic Diversity / 02.04.2019

MedicalResearch.com Interview with: Teryl K. Nuckols, MD Vice Chair, Clinical Research Director, Division of General Internal Medicine Cedars-Sinai Medical Center  MedicalResearch.com: What is the background for this study?   Response: Healthcare policymakers have long worried that value-based payment programs unfairly penalize hospitals treating many African-American patients, which could worsen health outcomes for this group. For example, policy experts have suspected that the Medicare Hospital Readmission Reduction Program unevenly punishes institutions caring for more vulnerable populations, including racial minorities. They've also feared that hospitals might be incentivized to not give patients the care they need to avoid readmissions. The study Investigators wanted to determine whether death rates following discharges increased among African-American and white patients 65 years and older after the Medicare Hospital Readmission Reduction Program started.

Author Interviews, Heart Disease, JAMA, Lipids / 02.04.2019

MedicalResearch.com Interview with: Victor Wenze Zhong, Ph.D. Postdoctoral fellow Department of Preventive Medicine Feinberg School of Medicine Northwestern University Chicago, IL 60611  MedicalResearch.com: What is the background for this study? Response: Dietary cholesterol is a common nutrient in human diet. Eggs, specially egg yolks, are the single richest source of dietary cholesterol among all commonly consumed foods. The associations between dietary cholesterol consumption and cardiovascular disease and mortality remain controversial despite decades of research. Eating less than 300 mg of dietary cholesterol per day was the guideline recommendation before 2015. However, the most recent 2015-2020 Dietary Guidelines for Americans no longer include a daily consumption limit for dietary cholesterol and recommend weekly egg consumption as part of the healthy US-style eating pattern. Whether these recommendations are appropriate have been intensely debated. (more…)
