Author Interviews, CDC, JAMA, Opiods / 12.02.2019

MedicalResearch.com Interview with: Gery Guy, PhD, MPH Injury Center CDC MedicalResearch.com: What is the background for this study? Response: This study examined opioid prescribing at the national and county-level in 2015 and 2017. During 2015 to 2017, the amount of opioids prescribed decreased 20.1% in the United States. The amount of opioids prescribed per person varies substantially at the county-level. The average amount of opioids prescribed in the highest quartile of counties was nearly 6 times the amount in the lowest quartile. Reductions in opioid prescribing could be related to policies and strategies aimed at reducing inappropriate prescribing, increased awareness of the risks associated with opioids, and release of the CDC Guideline for Prescribing Opioids for Chronic Pain.

Author Interviews, Genetic Research, JAMA, Race/Ethnic Diversity, Stroke / 11.02.2019

MedicalResearch.com Interview with: Sandro Marini, MD Research Fellow Jonathan Rosand Laboratory Massachusetts General Hospital Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The epsilon(ε) 4 allele of the Apolipoprotein E (APOE) gene increases risk for Alzheimer’s disease (AD) and intracerebral hemorrhage (ICH). In both diseases, it is believed to increase risk through the deposition of beta-amyloid within the brain and blood vessels, respectively. The effect of APOE ε4 on both AD and ICH risk changes across populations, for unclear reasons. In our study, we confirmed the role of APOE ε4 for ICH risk in whites and found that the risk-increasing effect of the 4 allele is demonstrable in Hispanics only when balancing out the effect of hypertension.

What are the main findings?  Response: Patients who receive a kidney transplant as treatment for end stage kidney disease are at risk of malignancy due to immunosuppression. In contrast to other solid organ transplant types, when kidney transplants fail it is possible for recipients to return to dialysis. Immunosuppression is usually reduced or completely stopped when  the allograft fails due to the risk of infection on dialysis. We decided to investigate what the trajectory of risk for non-melanoma skin cancer and invasive cancers overall (composite group) looked like for patients who have received multiple consecutive kidney transplants with intervening periods of graft failure. We compared cancer risk during periods of allograft failure and periods of functioning kidney transplants.   (more…)
Author Interviews, Health Care Systems, JAMA, Stroke, University Texas / 11.02.2019

MedicalResearch.com Interview with: Amrou Sarraj, MD, Associate Professor Department of Neurology McGovern Medical School The University of Texas Health Science Center at Houston. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Secondary analyses of trials showing efficacy and safety of thrombectomy within 6-8 hours of stroke onset showed that patients who were transferred to centers performing thrombectomy from another hospital had worse outcomes than patients who presented directly to the thrombectomy centers. We wanted to assess if the thrombectomy outcomes differ between transferred patients and patients directly coming to the thrombectomy centers when patients are selected with advanced perfusion imaging. We found that thrombectomy outcome rates were similar between patients who presented directly vs transferred from another hospital, including functional independence and safety outcomes.  (more…)
Author Interviews, Diabetes, JAMA, Metabolic Syndrome, Stroke / 10.02.2019

MedicalResearch.com Interview with: David Spence M.D., FRCPC, FAHA Professor of Neurology and Clinical Pharmacology Director, Stroke Prevention & Atherosclerosis Research Centre, Robarts Research Institute, Western University London, ON Canada MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The motivation for the study was the chair of the committee that advises the Ontario Drug Benefit which medications to pay for said the IRIS results were not relevant to clinical practice. This because the Insulin Resistance Intervention after Stroke (IRIS) trial reported effects of pioglitazone in patients with stroke or TIA and insulin resistance assessed by the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) score for insulin resistance.1 ( However, few clinicians measure a HOMA-iR score, so the clinical impact of that trial was limited. In this study we analyzed the effect of pioglitazone in stroke/TIA patients with prediabetes, which is commonly assessed by clinicians. Prediabetes was defined by the American Diabetes Association: a glycosylated hemoglobin (A1C) of  5.7% to <6.5% (we did not do glucose tolerance tests).  We analyzed primarily the results for patients with 80% adherence, but also did  an intention-to-treat (ITT) analysis.  The reason for focusing on patients with good adherence was that pioglitazone cannot be taken by about 10-20% of patients, because of fluid retention and weight gain (mainly due  to fluid retention).  (The reasoning was that third party payers would not need to pay for the medication in patients who do not take it.) In stroke/TIA patients with good adherence, the benefits of pioglitazone were greater than in the original IRIS trial. We found a 40% reduction of stroke/MI, a 33% reduction of stroke, and an 80% reduction of new-onset diabetes, over 5 years.  Pioglitazone also improved blood pressure, triglycerides and HDL-cholesterol. As expected, pioglitazone was somewhat less beneficial in the ITT analysis. Fluid retention can usually be managed by reducing the dose of pioglitazone; even small doses still have a beneficial effect . Also, amiloride has been shown to reduce fluid retention with pioglitazone.

Author Interviews, JAMA, MRI, Rheumatology / 07.02.2019

MedicalResearch.com Interview with: Signe Møller-Bisgaard MD, PhD Rigshospitalet Center for Rheumatology and Spine Diseases Copenhagen Center for Arthritis Research  MedicalResearch.com: What is the background for this study?  Response: The background was that to avoid long-term consequences of rheumatoid arthritis (RA) such as progressive joint damage progression leading to functional impairment and loss of quality of life, it is essential for patients with RA to achieve clinical remission, which is a disease state with no clinical signs and symptoms of disease activity. But despite treating our patients according to current clinical recommendations using targeted treatment strategies, so that the patients reach a state of remission, joint damage progression still occurs in one out of four patients. We knew, that MRI inflammatory findings such as synovitis and bone marrow edema are present in patients in clinical remission and are of prognostic value. In particular bone marrow edema has shown to be a strong predictor of erosive joint damage progression. In the IMAGINE-RA randomized clinical trial we therefore wanted to investigate if an MRI treat-to-target strategy targeting absence of bone marrow edema versus a conventional disease activity-guided treat-to-target strategy would improve clinical and radiographic outcome in rheumatoid arthritis patients in clinical remission.  (more…)
Anesthesiology, Author Interviews, JAMA, Surgical Research / 07.02.2019

MedicalResearch.com Interview with: Michael Avidan, MBBCh, FCA SA Dr. Seymour and Rose T. Brown Professor of Anesthesiology Chief of the Division of Clinical and Translational Research Director of the Infrastructure of Quality Improvement, Research and Informatics Washington University School of Medicine St Louis, MO  MedicalResearch.com: What is the background for this study? Response: Postoperative delirium, a temporary state of confusion and inattention, is common in older adults after major surgery. Delirium can be distressing to patients, family members and clinicians. It is associated with longer hospital stays, other medical complications, cognitive decline, and death. Some previous studies have found that using electroencephalography (EEG) monitoring of the brain during general anesthesia decreases the occurrence of delirium following surgery. Therefore we conducted a rigorous study to determine whether using information from the EEG to guide the safe reduction of inhaled anesthetic drugs would prevent postoperative delirium and improve other outcomes in older adults following major surgery.

MedicalResearch.com Interview with: John J. Leddy, MD Clinical Professor Department of Orthopaedics Jacobs School of Medicine & Biomedical Sciences University of Buffalo MedicalResearch.com: What is the background for this study? Response: Sport-related concussion (SRC) is a significant public health problem without an effective treatment. Recent International Guidelines have questioned the efficacy of recommending complete rest to treat concussion and have called for prospective studies to evaluate early active treatments for sport-related concussion.  (more…)
Author Interviews, Diabetes, Education, JAMA, Pediatrics / 06.02.2019

MedicalResearch.com Interview with: Niels Skipper PhD Associate Professor, Department of Economics and Business Economics Aarhus University MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is unclear if there is an association between type 1 diabetes and school performance in children. Some studies have found type 1 diabetes to be associated with worse performance, while others have found no differences. However, most of the existing literature are based on smaller, non-random samples of children with diabetes. In this study we used data on all public school children in the country of Denmark, involving more than 600,000 schoolchildren where approximately 2,000 had a confirmed diagnosis of type 1 diabetes. The children were tested in math and reading using a nationally standardized testing procedure, and we found no difference in the obtain test scores between children with diabetes compared to children without diabetes.  (more…)
Author Interviews, Cost of Health Care, Critical Care - Intensive Care - ICUs, Health Care Systems, Hospital Acquired, JAMA, Urinary Tract Infections / 06.02.2019

MedicalResearch.com Interview with: Heather Hsu, MD MPH Assistant Professor of Pediatrics Boston University School of Medicine Boston Medical Center Boston, MA 02118 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In October 2013, the Centers for Medicare and Medicaid Services (CMS) implemented value-based incentive programs to financially reward or penalize hospitals based on quality metrics. Two of these programs – Hospital Value Based Purchasing and the Hospital Acquired Condition Reduction Program – began targeting hospitals’ rates of certain healthcare-associated infections deemed to be preventable in October 2015. Previous studies demonstrated minimal impact of these value-based payment programs on other measures of hospital processes, patient experience, and mortality. However, their impact on healthcare-associated infections was unknown. Our goal was to study the association of value-based incentive program implementation with healthcare-associated infection rates, using catheter-associated urinary tract infection in intensive care units (one of the targeted outcomes) as an example. We found no evidence that federal value-based incentive programs had any measurable association with changes in catheter-associated urinary tract infection rates in the critical care units of US hospitals.

Author Interviews, JAMA, Ophthalmology, Pediatrics, STD, USPSTF / 05.02.2019

MedicalResearch.com Interview with: Michael Silverstein, M.D., M.P.H. Professor of Pediatrics Director of the Division of General Academic Pediatrics Vice chair of research for the Department of Pediatrics Boston University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gonococcal ophthalmia neonatorum, or GON, is a severe infection of the eye that can occur in babies born to women who have gonorrhea. If left untreated, GON can cause serious problems, including blindness, that can appear as soon as 24 hours after delivery. Fortunately, there are effective treatments available that can prevent GON in newborns. The U.S. Preventive Services Task Force reviewed the most current research on the benefits and harms of ocular prophylaxis—which is applying antibiotic ointment to the babies’ eyes at birth—to prevent GON. We found that, if applied within 24 hours after birth, the ointment is very effective at preventing gonococcal ophthalmia neonatorum and the problems it causes. Therefore, we are recommending that clinicians provide this preventive service for all newborns.  (more…)
Author Interviews, JAMA, Thyroid, Thyroid Disease / 04.02.2019

MedicalResearch.com Interview with: Joanna Klubo-Gwiezdzinska, M.D., Ph.D., M.H.Sc. Assistant Clinical Investigator/Assistant Professor Metabolic Disease Branch/NIDDK/NIH Bethesda, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: People with intermediate- and high-risk differentiated thyroid cancer (DTC) are treated with surgical removal of the thyroid gland and radioactive iodine therapy.  After surgery and initial treatment, the thyroid hormone levothyroxine is used for long-term management not only to replace appropriate physiologic thyroid hormones post-surgery, but also to suppress thyrotropin (TSH) release from the pituitary gland at supraphysiologic doses. The current recommended American Thyroid Association TSH suppression goal in patients with a high-risk differentiated thyroid cancer presenting with distant metastases is less than 0.1mIU/ml, and between 0.1-0.5 mIU/ml for patients with intermediate-risk DTC presenting with local metastases to the neck lymph nodes. This TSH goal is much lower than physiologic TSH level, which ranges between 0.4-4.1 mIU/ml, depending on the measurement method and person’s age. TSH suppression is used because some preclinical evidence suggests that TSH can stimulate growth of cancer cells.  However, several preclinical studies show that thyroid hormones may also stimulate cancer growth. In addition, too much levothyroxine, leading to TSH suppression, may cause side effects such as abnormal heart rhythms and decreased bone mass. In this study, based on a large multicenter database analysis, we found that continuous TSH suppression with levothyroxine was not associated with better progression-free survival and overall survival in patients with either intermediate- and high-risk differentiated thyroid cancer. The patients were followed for an average of 7 years after surgical thyroid cancer removal and radioactive iodine therapy.  (more…)
Antibiotic Resistance, Asthma, Author Interviews, JAMA / 04.02.2019

MedicalResearch.com Interview with: Mihaela S Stefan, MD, PhD FACP Research Scientist, Institute for Healthcare Delivery and Population Science Associate Professor, UMMS-Baystate Director of Perioperative Clinic and Medical Consultation Program Academic Hospitalist Director Quality Assessment, Division of Healthcare Quality Springfield MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: In a prior study we have found that roughly 41% of patients hospitalized with an asthma exacerbation receive antibiotics although the guidelines do not support this practice. We found that the evidence supporting the guidelines was however limited to 6 trials which included a total of only 681 adults and children and most trials’ outcomes were symptoms or lung function not length of stay, need for mechanical ventilation, readmissions or death. We performed the largest observational study to-date of approximately 20 000 patients hospitalized for asthma exacerbation and found that patients treated with antibiotics did not have better outcomes but instead they had longer hospital stay and an increased risk for antibiotic-related diarrhea.

MedicalResearch.com Interview with: Sheri Madigan, Ph.D, R.Psych Canada Research Chair in Determinants of Child Development Assistant Professor, Department of Psychology Alberta Children's Hospital Research Institute University of Calgary MedicalResearch.com: What is the background for this study? What are the main findings? Response: Parents are reporting that screen time is one of their major concerns, so we wanted to find out more about how large of a role screen time was playing on children’s developmental outcomes. We were especially interested in the long-term impact of screens, which is why we followed children over time, from ages 2 to 5 and repeatedly assessed both screen time use and children’s achievement of developmental milestones. There are three main findings:
  1. Our study revealed that on average children were viewing screens for 2.4, 3.6 and 1.6 hours per day at two, three and five years of age, respectively. This means that the majority of the participants in our sample are exceeding the American Academy of Pediatrics’ guideline.
  2. We found statistically significant, albeit small effects suggesting that greater amounts of screen time at two and three years predict poorer child outcomes at three and five years, respectively. Thus, screen time has a lasting influence on children’s development.
  3. The opposite pattern was not observed. That is, we did not find evidence that children showing poor performance in terms of achieving developmental milestones were more likely to be place in front of screens to help cope with their potentially challenging behaviors.

To view a copy of this license, visit: https://creativecommons.org/licenses/by/2.0Dr. Qiushi Chen (first author) and Jagpreet Chhatwal PhD Assistant Professor, Harvard Medical School Senior Scientist, Institute for Technology Assessment Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Opioid overdose epidemic is a national public health emergency — in 2017, more than 49,000 people died from overdose. Our study shows that under current conditions, the number of deaths is projected to increase to 81,700 by 2025. Efforts to curb the epidemic by reducing the incidence of prescription opioid misuse — the primary focus of current interventions — will have a modest effect of 3-5% reduction in overdose deaths.

MedicalResearch.com Interview with: Diane M. Gibson, Ph.D. Executive Director – New York Federal Statistical Research Data Center, Baruch RDC Associate Professor – Marxe School of Public and International Affairs, Baruch College - CUNY MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior studies have found that screening for diabetic retinopathy in primary care settings using telemedicine increased screening rates among individuals with diabetes and among subgroups of individuals with diabetes who are at high risk of missing recommended eye exams.  In a previous paper I looked at how often U.S. adults with diabetes visited primary care and eye care providers for recommended diabetes preventive care services using a sample from the 2007-2013 Medical Expenditure Panel Survey.  I found that while visits to eye care providers were often skipped, most adults with diabetes did visit primary care physicians.  I argued that these findings suggest that screening for diabetic retinopathy in primary care settings using telemedicine has the potential to fulfill unmet needs and reach most U.S. adults with diabetes. My brief report in JAMA Ophthalmology examines patterns of eye examination receipt and visits to primary care physicians among U.S. adults with diabetes using a sample from the 2016 National Health Interview Survey.  The report pays particular attention to individuals who are at high-risk of missing recommended eye exams. The study found that 87.7% of the sample of adults with diabetes visited a primary care physician in the past year and that, except for the uninsured subgroup, more than 78% of each high-risk subgroup visited a primary care provider in the past year.  (more…)

MedicalResearch.com Interview with: Laura DeFina, MD President and Chief Executive Officer Chief Science Officer The Cooper Institute MedicalResearch.com: What is the background for this study? Response: Several studies suggest that endurance athletes may be at higher risk for asymptomatic hardening of the coronary arteries.  These studies, however, have been done on small numbers of endurance athletes (ie – marathon runners) and do not show whether this increase in hardening actually leads to increase in heart attacks or death of cardiovascular disease. In our population of 21,758 generally healthy individuals (average age 52 years) who presented for a preventive medicine examination, we were able to evaluate for the presence of hardening and cardiovascular events in individuals who exercised high volumes (≥3000 MET·minutes/week or comparable to running 6 miles/hour for an hour 5 days a week) versus those exercising less.

Author Interviews, Hospital Readmissions, JAMA, Nursing / 29.01.2019

MedicalResearch.com Interview with: Marianne Weiss DNSc RN READI study Principal Investigator Professor of Nursing and Wheaton Franciscan Healthcare / Sister Rosalie Klein Professor of Women’s Health Marquette University College of Nursing Milwaukee Wi, 53201-1881 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our team of researchers has been studying the association of patient readiness for discharge and readmission for several years. We have previously documented that patients who had ‘low readiness’ on our Readiness for Hospital Discharge Scale were more likely to be readmitted. In this study we added structured protocols for discharge readiness assessment and nurse actions to usual discharge care practices to determine the optimal protocol configuration to achieve improved post-discharge utilization outcomes. In our primary analysis that included patients from a broad range of patient diagnoses, we did not find a significant effect on readmission from adding any of the discharge readiness assessment protocols. The patient sample came from Magnet hospitals, known for high quality care, and the average all-cause readmission rates were low (11.3%). In patients discharged from high-readmission units (>11.3%), one of the protocols was effective in reducing the likelihood of readmission. In this protocol, the nurse obtained the patients self-report of discharge readiness to inform the nurse’s discharge readiness assessment and actions in finalizing preparations for discharge. This patient-informed discharge readiness assessment protocol produced a nearly 2 percentage point reduction in readmissions. Not unexpectedly, in lower readmission settings, we did not see a reduction in readmission; not all readmissions are preventable. In the last phase of study, we informed nurses of a cut-off score for ‘low readiness’ and added a prescription for nurse action only in cases of ‘low readiness’; this addition to the protocol added burden to the nurses’ daily work and eliminated the beneficial effects, perhaps because it limited the nurse’s attention to only a subset of patients.  (more…)

MedicalResearch.com Interview with: Dr. Dawn Wiest, 7-day pledge after hospital admissionDawn Wiest, PhD Director, Action Research & Evaluation Camden Coalition of Healthcare Providers MedicalResearch.com: What is the background for this study? Response: Understanding the role of care transitions after hospitalization in reducing avoidable readmissions, the Camden Coalition launched the 7-Day Pledge in 2014 in partnership with primary care practices in Camden, NJ to address patient and provider barriers to timely post-discharge primary care follow-up. To evaluate whether our program was associated with lower hospital readmissions, we used all-payer hospital claims data from five regional health systems. We compared readmissions for patients who had a primary care follow-up within seven days with similar patients who had a later or no follow-up using propensity score matching. (more…)
Author Interviews, Heart Disease, JAMA, Thyroid Disease, Vanderbilt / 27.01.2019

MedicalResearch.com Interview with: Joe-Elie Salem, MD, PhD Associate Professor - MCU-PH, Sorbonne Université - INSERM - CIC, Clinical Pharmacology, Cardio-oncology, APHP, La Pitié-Salpêtrière, Paris, France Adjunct Associate Professor, Vanderbilt University Medical Center, Cardio-oncology Clinical Pharmacology, Nashville, TN MedicalResearch.com: What is the background for this study? What are the main findings? Response: A study by researchers at Vanderbilt University Medical Center has strengthened the link between thyroid function and atrial fibrillation (AF), an irregular heart rhythm that increases the risk of stroke and other heart-related complications. They phenome-wide association study scanned the medical records of more than 37,000 people for an association between genetically determined variation in thyroid stimulating hormone levels (a measure of thyroid function) and AF risk. Previous observational studies have found that subclinical hyperthyroidism, an overactive thyroid which does not meet the clinical threshold for diagnosis or treatment, nevertheless can increase the risk of atrial fibrillation.  But whether to treat subclinical hypo- or hyperthyroidism to reduce AF risk remains a matter of debate in the medical community.  (more…)

MedicalResearch.com Interview with: Dr. Ann Raldow MD MPH Assistant Professor Department of Radiation Oncology David Geffen School of Medicine UCLA  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Similar to women in other historically male-dominated fields, female radiation oncologists face unique obstacles in achieving many metrics of career success, including equal salary, research funding, and academic promotion. Our study of industry payments found that female radiation oncologists were less likely than their male colleagues to receive payments from industry and that these payments tended to be of smaller monetary value.

MedicalResearch.com Interview with: Jeff D. Williamson, MD Geriatric Medicine - Sticht Center Wake Forest Baptist Medical Center MedicalResearch.com: What is the background for this study? Response: A growing amount of epidemiologic research has suggested that higher blood pressure is associated with higher risk for dementia, including Alzheimer’s dementia. MedicalResearch.com: What are the main findings? Response: More than 9,300 ambulatory, community dwelling persons over age 50, 30% of whom were over the age of 75, were randomly assigned to a blood pressure goal of 120 vs 140.  Persons in the 120 group had a 19% lower risk for developing MCI an transitional stage between normal and dementia (P<.008).  There was a 17% lower risk for developing dementia but this only achieved a p value = 0.10.  The combined risk for both MCI and dementia was 15% lower in the 120 group (p<0.04).  The dementia outcome was the primary outcome but all the outcomes were pre-specified in the protocol at the beginning of the trial.  Unfortunately the blood pressure intervention was stopped after only 3.3 years due to CVD and mortality benefit and this may well have influenced the ability to reach the expected number of dementia cases.  (more…)
Accidents & Violence, Author Interviews, Emergency Care, JAMA, Yale / 24.01.2019

MedicalResearch.com Interview with: Edouard Coupet Jr, MD, MS Assistant Professor Department of Emergency Medicine Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: For many individuals with nonfatal firearm injuries, their only point of contact with the healthcare system may be the emergency department. Both hospital-based violence intervention programs and counseling and safe firearm storage have shown promise in reducing the burden of firearm injury. In this study, one third of individuals with firearm injuries presented to non-trauma centers. Only 1 out of 5 firearm injuries were assault injuries that led to admission to trauma centers, the population most likely to receive interventions to reduce re-injury.  (more…)
Author Interviews, Duke, JAMA, Mental Health Research, Pediatrics, Toxin Research / 23.01.2019

MedicalResearch.com Interview with: Aaron Reuben, MEM Department of Psychology and Neuroscience Duke University, Durham, North Carolina MedicalResearch.com: What is the background for this study? What are the main findings? (1)  Study members with greater lead exposure in childhood tended to endorse more psychiatric symptoms when assessed for psychiatric disorders in adulthood (between 18 and 38 years of age).
  1. These individuals tended to report more internalizing (e.g., depression, anxiety) and thought disorder (e.g., OCD, schizophrenia, mania) symptoms.
  2. Compared to other findings from this sample, the associations reported in this article are similar to those reported for lead and IQ, and are stronger than those reported for lead and criminal offending.
    1. Informants who knew Study members well reported higher levels of difficult adult personality traits among Study members with greater lead exposure in childhood.
    2. Specifically, Study members with greater blood lead levels at age 11 were rated as more neurotic, less agreeable, and less conscientious by 38 years of age.
    3. These personality traits have been previously linked to a number of poor life outcomes, including greater psychopathology, worse physical health, less job satisfaction, and troubled interpersonal relationships
  3. Psychiatric problems related to lead exposure could be detected as early as 11 years of age. In the 1980’s, parents and teachers of children with higher blood-lead levels had described them as displaying more antisocial behavior, hyperactivity, and negative emotions (e.g., sadness, anxiety).

MedicalResearch.com Interview with: Miriam Vos, MD, MSPH Associate Professor of Pediatrics and Director Pediatric Fatty Liver Program Emory and Children’s Healthcare of Atlanta MedicalResearch.com: What is the background for this study? What are the main findings? Response: Fatty liver disease has quickly become a common problem in children and adolescents, affecting an estimated 7 million children in the U.S.  This study resulted from our previous research demonstrating that fructose increases cardiometabolic risk factors in children with NAFLD in addition to other research that had demonstrated associations between NAFLD and sugar.    (more…)
Author Interviews, End of Life Care, JAMA, Kidney Disease / 22.01.2019

MedicalResearch.com Interview with: Susan P. Y. Wong, MD MS Assistant Professor Division of Nephrology University of Washington VA Puget Sound Health Care System  MedicalResearch.com: What is the background for this study? Response: Patients who reach the advanced stages of kidney disease  must often face the difficult decision of whether to undergo maintenance dialysis. While maintenance dialysis is a remarkable therapy that has extended the lives of many patients, its benefits do not necessarily accrue in older patients with significant comorbidity and functional impairment. It is also a very demanding form of therapy that comes with its own burdens and complications. Based on our prior research in the national VA health system, 1 in 7 patients with very advanced kidney disease (or their decision makers) do not pursue dialysis. We wanted to understand how these decisions to forgo initiation of maintenance dialysis unfold. (more…)
Author Interviews, Diabetes, Infections, JAMA, Pediatrics, Vaccine Studies / 22.01.2019

MedicalResearch.com Interview with: Dr Kirsten Perrett MBBS FRACP PhD Team Leader / Clinician-Scientist Fellow, Population Allergy, Murdoch Children's Research Institute Consultant Paediatrician, Department of Allergy and Immunology and General Medicine The Royal Children's Hospital Fellow, School of Population and Global Health The University of Melbourne Parkville, Victoria  Australia MedicalResearch.com: What is the background for this study? Response: Before rotavirus vaccines were available, rotavirus infection was the most common cause of severe gastroenteritis in infants and young children. Because it is so contagious, infection in childhood is thought to be universal in unvaccinated children. Previous studies indicated that rotavirus infection of infants might be an environmental promoter of type 1 diabetes. Therefore, we anticipated that the introduction of the rotavirus vaccine might alter the disease incidence in young children.  (more…)

MedicalResearch.com Interview with: medicalresearch.comDr. Marie Joelle Jabagi, PharmD, MPH University of Paris Sud, Paris-Saclay University, Paris Health Product Epidemiology Department French National Agency for Medicines and Health Products Safety Saint-Denis, France MedicalResearch.com: What is the background for this study? Response: Secondary hematologic malignant neoplasms that develop months or years after the diagnosis of breast cancer may be a consequence of genetic predisposition, environmental factors, previous cancer treatments or a combination of all those factors. These secondary malignant neoplasms are increasingly becoming a concern given that the population of breast cancer survivors is growing substantially. However, their frequency in real life has been poorly investigated to date. The aims of our research were to estimate the frequency of various types of hematologic malignant neoplasm following a diagnosis of primary breast cancer among women aged 20 to 85 years in France during the past decade, and to compare it to the corresponding frequency in women of the French general population.
