Author Interviews, Education, JAMA, Outcomes & Safety, Surgical Research / 24.04.2017

MedicalResearch.com Interview with: Haggi Mazeh, MD, FACS Endocrine and General Surgery Department of Surgery Hadassah-Hebrew University Medical Center, Mount Scopus Jerusalem, Israel 91240 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The level of operating room autonomy given to surgical residents varies greatly between different institutions and different countries. On one hand, providing residents the opportunity to operate alone augments their confidence and their sense of responsibility, possibly accelerating their learning process. On the other hand, it may be argued that the presence of a senior general surgeon in every operation is a safer approach. Before 2012, a large proportion of appendectomies at our institution were performed by surgical residents alone. After 2012, our institutional policy changed to require the presence of a senior general surgeon in every appendectomy case. This unique situation provided us the opportunity to compare the outcomes of appendectomies performed by residents alone to those performed in the presence of a senior general surgeon. Our study demonstrated no difference in the complication rates between the two groups of patients. However, surgeries performed in the presence of senior general surgeons were significantly shorter than those performed by residents. (more…)
Addiction, Author Interviews, Infections, JAMA, Ophthalmology / 22.04.2017

MedicalResearch.com Interview with: Aubrey Tirpack, PGY3 New England Eye Center Tufts Medical Center  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Intravenous drug abuse is a known risk factor for the development of endogenous fungal endophthalmitis (EFE), a severe intraocular infection cause by the seeding of mycotic organisms to the eye. Our institution noted a marked increase in cases of EFE beginning in May 2014, which correlates to increasing rates of opioid abuse throughout the New England region. Ten patients were found to have intravenous drug abuse related EFE over the two year time period studied. The most common presenting symptoms were floaters, decreased vision, and pain. All patients were treated with systemic antifungals and nine patients underwent intravitreal antifungal injection. All patients were ambulatory at presentation and the majority were without systemic signs of infection. (more…)
Aging, Author Interviews, Breast Cancer, JAMA, Mammograms, NYU / 21.04.2017

MedicalResearch.com Interview with: Cindy S. Lee, MD Department of Radiology and Biomedical Imaging University of California, San Francisco, San Francisco Now with Department of Radiology NYU Langone Medical Center, Garden City, New York MedicalResearch.com: What led you and colleagues to conduct this study? Response: I am a breast imager. I see patients who come in for their screening mammograms and I get asked, a lot, if patients aged 75 years and older should continue screening, because of their age. There is not enough evidence out there to determine how breast cancer screening benefits women older than 75. In fact, all previously randomized trials of screening mammography excluded people older than 75 years. Unfortunately, age is the biggest risk factor for breast cancer, so as patients get older, they have higher risks of developing breast cancer. It is therefore important to know how well screening mammography works in these patients. (more…)
Author Interviews, Inflammation, JAMA / 20.04.2017

MedicalResearch.com Interview with: Andrew Dick FRSB FMedSci Professor of Ophthalmology Bristol Eye Hospital, University of Bristol, Bristol, England National Institute for Health Research Biomedical Research Centre, Moorfields Eye Hospital, Institute of Ophthalmology, University College London, London, England and John Sheppard, MD President, Virginia Eye Consultants Professor of Ophthalmology, Eastern Virginia Medical School MedicalResearch.com: What should readers take away from your report? Dr. Andrew Dick: These findings demonstrate that adalimumab is associated with clinically meaningful improvements in visual functioning for patients with non-infectious intermediate uveitis, posterior uveitis, and panuveitis. The emphasis of this work is that for the first time in uveitis we have seen patient reported outcome benefit of a biologic treatment. This analysis supports the use of adalimumab as a promising new treatment option, having demonstrated improvements in both clinical and visual functioning outcomes in patients with active and inactive uveitis. Dr. John Sheppard: Uveitis has a substantial effect on individuals’ physical, professional, psychological, avocational and social functioning in day-to-day life. Adalimumab, an anti-inflammatory drug that binds to tumor necrosis factor, was recently approved for the treatment of non-infectious intermediate uveitis, posterior uveitis, and panuveitis. It is the first systemic therapy specifically approved for uveitis.  The analyses in this study provide evidence that patients with noninfectious uveitis treated with adalimumab experience significant and clinically meaningful improvements in vision-related quality of life, compared with those who received placebo.

Author Interviews, Blood Pressure - Hypertension, Gender Differences, JAMA, Race/Ethnic Diversity / 20.04.2017

MedicalResearch.com Interview with: Shakia Hardy, MPH, CPH. PhD Department of Epidemiology The University of North Carolina at Chapel Hill MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies characterizing blood pressure levels across the life course have relied on prevalence estimates at a given age. Our study was interested in identifying critical ages at which net transitions between levels of blood pressure occurred. We used data from the National Health and Nutrition Examination Survey (2007-2012) to estimate age-, race-, and sex-specific annual net transition probabilities between ideal blood pressure, prehypertension and hypertension. We found that African Americans and men were more likely to transition from ideal levels of blood pressure in childhood or early adulthood compared to white Americans and women, which puts them at increased risk of developing prehypertension and hypertension earlier in life.

Author Interviews, Compliance, Heart Disease, JAMA / 20.04.2017

MedicalResearch.com Interview with: Robert Rosenson, MD Professor of Medicine and Cardiology Icahn School of Medicine at Mount Sinai New York MedicalResearch.com: What is the background for this study? What are the main findings? Response: High intensity statin therapy is underutilized in patients with acute coronary syndromes. In 2011, 27% of patients were discharged on a high intensity statin (Rosenson RS, et al. J Am Coll Cardiol). In this report, we investigate the factors associated with high adherence to high intensity statin. High adherence to high intensity statins was more common among patients who took high intensity statin prior to their hospitalization, had fewer comorbidities, received a low-income subsidy, attended cardiac rehabilitation and more visits with a cardiologist.

Author Interviews, Breast Cancer, Chemotherapy, JAMA, MD Anderson, Surgical Research / 20.04.2017

MedicalResearch.com Interview with: Audree Tadros, MD, MPH Chief Administrative Fellow, Breast Surgical Oncology Training Program Department of Breast Surgical Oncology MD Anderson Cancer Center and Henry M. Kuerer, MD, PhD, FACS Executive Director, Breast Programs MD Anderson Cancer Network PH and Fay Etta Robinson Distinguished Professor in Cancer Research Dept of Breast Surgical Oncology Director, Breast Surgical Oncology Training Program MedicalResearch.com: What is the background for this study? Response: Neoadjuvant chemotherapy (NCT) has the ability to confer a pCR (pathologic complete response-when no residual cancer is found) in both the breast and axillary lymph nodes. We know that this is most likely to occur in women with HER2 positive and triple negative disease. The high rate of pCR among these patients raises the question of whether surgery is still required, particularly among those who will receive adjuvant radiation therapy. Until recently, we lacked the ability to pre-operatively predict patients who achieved a breast pCR. Recently, we completed a clinical feasibility trial examining the ability of image-guided biopsy to predict a pCR after neoadjuvant chemotherapy. Our biopsy technique was able to accurately predict a pCR in 98% of patients with only a 5% false negative rate. Based upon these findings, we believe we can accurately determine which patients achieve a breast pCR. This led us to develop a clinical trial to see if breast surgery is redundant in patients who achieve a pCR. An important question that remained was if we are going to omit breast surgery in these exceptional responders, can we also omit axillary surgery? (more…)
Author Interviews, Autism, Depression, JAMA, OBGYNE, Pediatrics / 19.04.2017

MedicalResearch.com Interview with: Simone Vigod, MD, MSc, FRCPC Psychiatrist and Lead, Reproductive Life Stages Program Women’s Mental Health Program Women’s College Hospital Toronto, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: Depression is one of the most common problems that can complicate a pregnancy. Untreated, or incompletely treated, it can be associated with significant harm to mother and child. While psychotherapies alone may be effective for women with mild (or even moderate) severity symptoms, sometimes antidepressant medication is required. In these cases, the benefits of treatment must be weighed against potential risks. Previous research suggested that there may be an increased risk for autism in children exposed to antidepressant medication during pregnancy. However, previous studies were limited in their ability to account for other potential causes of autism in their analyses. In our study, we used several different strategies to try to compare children whose pregnancy exposures were very similar, except for exposure to an antidepressant. The main finding was that after using these strategies, there was no longer a statistically significant association between in-utero antidepressant exposure and autism. (more…)
Author Interviews, JAMA / 19.04.2017

MedicalResearch.com Interview with: Neha Pagidipati, MD MPH Duke Clinical Research Institute Duke University Durham, North Carolina MedicalResearch.com: What is the background for this study? What are the main findings? Response: The 2013 ACC/AHA guidelines for treatment of blood cholesterol to prevent cardiovascular disease created a new paradigm for lipid management and raised numerous ongoing controversies. In 2016, the US Preventive Services Task Force released recommendations for primary prevention statin therapy which were different in some important ways from the 2013 ACC/AHA guidelines. We aimed to understand the practical difference between these two sets of guidelines in terms of the number of Americans who would be potentially eligible for statin therapy. Using U.S. cross-sectional survey data between 2009 and 2014, we found that, if fully implemented, the USPSTF recommendations would reduce the percentage of US adults age 40-75 who should initiate statin therapy from 24% to 16% as compared to the 2013 ACC/AHA guidelines. Those newly recommended for statin therapy would be in addition to the 21% of US adults already taking lipid-lowering therapy. Of the approximately 9 million adults who would no longer be recommended to receive statin therapy under the new USPSTF recommendations, over half of them would be younger adults with a high long-term risk of cardiovascular disease (about 1 in 3), and over one quarter would be individuals with diabetes.

Author Interviews, Cancer Research, Genetic Research, JAMA / 18.04.2017

MedicalResearch.com Interview with: Fergus J. Couch, Ph.D. Zbigniew and Anna M. Scheller Professor  of Medical Research Chair, Division of Experimental Pathology Department of Laboratory Medicine  and Pathology Mayo Clinic Rochester, MN MedicalResearch.com: What is the background for this study? What are the main findings? Response: The main finding is that RAD51D, BARD1, and MSH6 can now be included in the list of moderate risk breast cancer genes. In contrast, other genes such as MRE11A and RAD50 do not increase risk of breast cancer. In addition, we provide initial estimates of the level of breast cancer risk associated with mutations in the genes that cause breast cancer. The "new" breast cancer genes may now be useful for identifying women who can benefit from enhanced screening. These new data will need to be considered by the National Comprehensive Cancer Network (NCCN) which provides guidelines for clinical management of individuals with mutations in cancer predisposition genes. These results will also be useful for identifying members of families who are at increased risk of breast cancer. (more…)
Author Interviews, JAMA, Opiods, Surgical Research, University of Michigan / 18.04.2017

MedicalResearch.com Interview with: Chad M. Brummett, MD Division of Pain Medicine, Department of Anesthesiology University of Michigan Medical School Ann Arbor, MI 48109  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The opioid epidemic has received considerable attention, but most of the focus has been on chronic pain and primary care. However, surgeons prescribe ~40% of the opioids in the US, and little attention has been given to the importance of prescribing after surgery. In this study, we found that among patients not using opioids in the year prior to surgery, ~6% of patients continued to use opioids long after what would be considered normal surgical recovery. Furthermore, there was no difference between patients undergoing minor and major surgeries, thereby suggesting that some patients continue to use opioids for reasons other than pain related to surgery.

Author Interviews, JAMA, Johns Hopkins, Mammograms / 18.04.2017

MedicalResearch.com Interview with: Archana Radhakrishnan MD MHS Division of General Internal Medicine Johns Hopkins University Baltimore, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: We were interested in understanding the current practice trends in breast cancer screening recommendations by doctors in light of the guideline changes.  We performed a national survey of primary care providers and gynecologists asking about their breast cancer screening practices. We found that a large number of doctors recommend breast cancer screening to younger and older women—upwards of 80% of doctors recommend it for younger women (ages 40-44) and almost 70% for women 75 and older.  But this varies by the type of doctor that a woman see.  Gynecologists were, in general, more likely to recommend routine mammograms.

Author Interviews, Heart Disease, HIV, JAMA, Vanderbilt / 18.04.2017

MedicalResearch.com Interview with: Matthew S Freiberg, MD, MSc Associate Professor of Medicine, Division of Cardiovascular Medicine Vanderbilt Translational and Clinical Cardiovascular Research Center MedicalResearch.com: What is the background for this study? Response:  HIV infected people are living longer and are at risk for cardiovascular diseases. While acute myocardial infarction has been studied and the increased risk of Acute Myocardial Infarction (AMI) among HIV+ people compared to uninfected people is well documented, there are less data describing the risk of HIV and different types of heart failure, including reduced and preserved ejection fraction heart failure. Understanding more about the link between HIV and different types of HF is important because reduced and preserved ejection fraction heart failure differ with respect to underlying mechanism, treatment, and prognosis. Moreover, as cardiovascular care has improved, HIV infected people who experience an AMI are likely to survive but may live with a damaged heart. Understanding more about the link between HIV and heart failure may help providers and their patients prevent or reduce the impact of HF on the HIV community. (more…)
AstraZeneca, Author Interviews, Autism, Boehringer Ingelheim, Depression, Eli Lilly, J&J-Janssen, JAMA, Merck, OBGYNE / 17.04.2017

MedicalResearch.com Interview with: Florence Gressier MD PhD Insermk Department of psychiatry CHU de Bicêtrem Le Kremlin Bicêtre France MedicalResearch.com: What is the background for this study? What are the main findings? Response: Results from recent studies have suggested an increased risk for Autism Spectrum Disorders (ASDs) in children exposed to antidepressants in utero. We performed a systematic review of and a meta-analysis of published studies to assess the association between ASDs and fetal exposure to antidepressants during pregnancy for each trimester of pregnancy and preconception. Our systematic review and meta-analysis suggests a significant association between increased ASD risk and maternal use of antidepressants during pregnancy; however, it appears to be more consistent during the preconception period than during each trimester. In addition, the association was weaker when controlled for past maternal mental illness. Maternal psychiatric disorders in treatment before pregnancy rather than antenatal exposure to antidepressants could have a major role in the risk for Autism Spectrum Disorders. (more…)
Author Interviews, Hepatitis - Liver Disease, JAMA / 14.04.2017

MedicalResearch.com Interview with: Joshua Barocas, MD Clinical and Research Fellow Division of Infectious Diseases Massachusetts General Hospital and Brigham and Women's Hospital  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Boston Health Care for the Homeless Program began treating HCV-infected individuals with the new oral medications. Based on clinical experience and previous experience with medication adherence in the setting of HIV, there were no clinical reasons that homeless persons should be excluded. As a result, we began to track the experience of treated individuals including cure, side effects, and adherence. We found that in the initial group of treated individuals, 62 of 64 persons achieved SVR. There were minimal side effects and adherence was excellent.  (more…)
Author Interviews, Boehringer Ingelheim, Diabetes, JAMA, Ophthalmology / 13.04.2017

MedicalResearch.com Interview with: Marco A Zarbin, MD, PhD, FACS Alfonse Cinotti, MD/Lions Eye Research Professor and Chair Institute of Ophthalmology & Visual Science Rutgers-New Jersey Medical School Rutgers University Newark, NJ 0710  MedicalResearch.com: What is the background for this study? What are the main findings?
  1. Most large, randomized clinical trials are powered to assess the efficacy of drugs or interventions, but they usually do not enroll enough patients to accurately assess the frequency of uncommon, undesirable side effects.
  2. In order to compensate for this deficiency in trial design, investigators aggregate the results of numerous studies all of which address the same clinical question with the same (or similar) drugs/interventions to increase the power to detect uncommon side effects. These aggregate studies can be meta-analyses.
  3. Unfortunately, most meta-analyses do not have the ability to answer some critical questions such as the timing of an adverse event relative to the last exposure to the drug, nor can they compensate fully for differences among the aggregated studies in trial design, length of patient follow-up, or presence pre-existing risk factors for the side effects in question.
  4. A pooled analysis of combined clinical trials using patient level data, however, allows a more in depth analysis of side effects than study level data, which are usually used for most published meta-analyses, because patient level data allow one to incorporate the per-patient duration of exposure to treatment, adjust for imbalances in predefined baseline risk factors, and adjust for the effect of results of single studies on the overall result.

Author Interviews, Heart Disease, JAMA, Vitamin D / 13.04.2017

MedicalResearch.com Interview with: Robert Scragg, MBBS, PhD School of Population Health The University of Auckland Auckland New Zealand MedicalResearch.com: What is the background for this study? What are the main findings? Response: Interest in a possible role for vitamin D deficiency as a risk factor for cardiovascular disease was stimulated by studies showing a seasonal variation in cardiovascular disease, which is much higher in winter, when body levels of vitamin D are low, than in summer. Main findings are that bolus monthly doses of vitamin D supplementation do not prevent against cardiovascular disease, even in people with low levels of vitamin D. (more…)
Author Interviews, Heart Disease, JAMA, Lipids, Nutrition, Stroke, Yale / 13.04.2017

MedicalResearch.com Interview with: Eric J. Brandt, MD Yale University Cardiovascular Disease Fellow MedicalResearch.com: What is the background for this study? What are the main findings? Response: From previous studies we know that industrial trans fatty acid (trans fat) consumption is linked to elevated risk for cardiovascular disease. Even small amounts of consumption can be deleterious to cardiovascular health. In New York state, there were 11 counties that restricted the use of trans fatty acids in eateries. We compared hospitalization for heart attacks and stroke from 2002 through 2013 in counties that did and did not have restrictions. Our study found that when comparing populations within New York state that restricted the use of trans fat, compared to those that did not, there was an associated additional decline beyond temporal trends for heart attacks and stroke events combined by 6.2%.

Author Interviews, End of Life Care, JAMA / 10.04.2017

MedicalResearch.com Interview with: Charles D. Blanke, M.D., F.A.C.P., F.A.S.C.O. CHAIR, SWOG Professor, OHSU Knight Cancer Institute Marquam II MedicalResearch.com: What is the background for this study? What are the main findings? Response: Oregon’s Death with Dignity Act as a voter initiative which law in 1997 – the first of its kind in the nation. Now, physician aid-in-dying is spreading quickly, with the states of Washington, Vermont, Colorado, and California passing similar legislation, as well as the District of Columbia, and Montana (through a court ruling). Millions of Americans lives in states where they would have the opportunity, if they were terminally ill, to take a lethal dose of medication with a doctor’s prescription. My team here at SWOG, a global cancer research community that designs and conducts publicly funded clinical trials, wanted to look at Oregon’s 18 years of aid-in-dying data and answer some simple questions: Who is using the law? Why? Are the drugs effective? What are the trends in actually taking the prescribed medications? We found that use of law has mostly increased over time – and substantially increased in 2014 and 2015. We found that predominantly white, older, well-educated people, take advantage of the law, and many of them – 77 percent – have underlying terminal cancer. The medication is also 99.4 percent effective. (more…)
Author Interviews, Autism, Environmental Risks, JAMA, Toxin Research / 10.04.2017

MedicalResearch.com Interview with: Keith Fluegge BS Institute of Health and Environmental Research (IHER) Cleveland Graduate School, The Ohio State University, Columbus Ohio MedicalResearch.com: What is the background for this study? What are the main findings? Response: The research letter discusses the possible link between rainfall precipitation and risk of autism. Earlier research suggested a link, although there remained quite a bit of skepticism surrounding the findings at the time. The purpose of the study was to briefly highlight the role of environmental exposure to the agricultural and combustion pollutant, nitrous oxide (N2O), as a possible etiological factor in neurodevelopmental disorders. We have published a series of epidemiological investigations, reviews, and correspondences discussing this possibility. In my continued research on this topic, I learned that rainfall and extreme weather-related events, like hurricanes, drive N2O emissions, especially from nitrogen amended soils. Exposure to this particular air pollutant may, therefore, plausibly undergird the relationship between rainfall precipitation and risk of autism. (more…)
Author Interviews, Cost of Health Care, JAMA, Primary Care, UCLA / 10.04.2017

MedicalResearch.com Interview with: John N. Mafi, MD, MPH Assistant Professor of Medicine Division of General Internal Medicine and Health Services Research UCLA David Geffen School of Medicine Los Angeles, CA 90024 Affiliated Natural Scientist in Health Policy RAND Corporation 1776 Main St, Santa Monica, CA 90401 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Between 10-30% of healthcare costs are due to low value care, or patient care that provides little to no benefit to patients, and can sometimes cause harm (e.g., radiation exposure from diagnostic imaging tests). In this study, we found that hospital-based primary care practice provide more low value care than community-based primary care practices across the United States. Understanding where and why low value care occurs is going to be essential if we want to get serious about eliminating it. (more…)
Author Interviews, CDC, JAMA, Stroke / 10.04.2017

MedicalResearch.com Interview with: Mary G. George, MD, MSPH Division for Heart Disease and Stroke Prevention National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: Stroke is the fifth leading cause of death in the United States, killing more than 130,000 Americans each year—that’s 1 of every 20 deaths—and costs the nation $33 billion annually, including the cost of health care services, medications, and lost productivity. And, stroke is leading cause of serious disability. An ischemic stroke, sometimes called a brain attack, is a stroke that occurs when there is a blockage of the blood supply to the brain. (more…)
Accidents & Violence, Author Interviews, JAMA, Karolinski Institute, Mental Health Research / 06.04.2017

MedicalResearch.com Interview with: Hanna Sahlin MSc, Lic psychologist, Lic psychotherapist Specialist in clinical psychology PhD-student Departement of Clinical Neuroscience Karolinska Institutet National Self-harm project Centre for Psychiatry Research, CPF Stockholm, Sweden What is the background for this study? What are the main findings? Response: This study is the result of wanting to find a more conclusive answer to whether individuals who engage in non-fatal deliberate self-harm are more prone to aggression towards others. There has long been a debate on whether aggression to oneself and aggression towards others co-occur, but the studies that have been conducted thus far have been on smaller samples or with clinical or forensic cohorts. Also, the studies have had great variability regarding the definition of both “deliberate self-harm” and “violence”. Thus, it has been difficult to establish an ”overall” effect size for this association, or to draw firmer conclusions on how and if this association plays out in the general population. We had the opportunity to study this association in several large nationwide population-based registries including all Swedish citizens, and with high specificity regarding the ingoing variables of interest – i.e., non-fatal deliberate self-harm (as registered in the National Patient Register) and violent crime convictions (as registered in the National Crime Register). We found a five times increased crude risk (hazard) of being convicted of a violent crime if one had received self-harm associated clinical care, and vice-versa, that there was an equally increased risk of self-harm if one had been convicted of a violent crime. After controlling for relevant psychiatric comorbidities and socio-economic status, an almost doubled risk of violent crime conviction remained among self-harming men and women compared to individuals not exposed to self-harm. It is important to notice that our study did not find any evidence suggesting that self-harm behaviours cause violent criminality. Therefore, we conclude that the engagement in violence towards oneself and towards others share an underlying vulnerability to impulsive and aggressive behaviours. (more…)
Author Interviews, Global Health, JAMA, Pediatrics / 06.04.2017

MedicalResearch.com Interview with: Dr. Nicholas Kassebaum, MD Assistant Professor Institute for Health Metrics and Evaluation University of Washington MedicalResearch.com: What is the background for this study? Response: Reducing deaths of young children has been an international priority over the past few decades, and much progress has been made in this regard. Comprehensive and timely measurement of death and disease burden among children and adolescents is essential for improving the health of young people. Analyzing the latest estimates from the Global Burden of Disease (GBD), the current study quantifies and describes levels and trends of mortality and disease burden among children and adolescents under the age of 19 from 1990 to 2015.

MedicalResearch.com Interview with: Neda Razaz-Vandyke, PhD, MPH Postdoctoral Fellow Reproductive Epidemiology Unit Karolinska Institutet   MedicalResearch.com: What is the background for this study? What are the main findings? Response:   There is a growing concern about long-term neurological effects of prenatal exposure to maternal overweight and obesity. The etiology of epilepsy is poorly understood and in more than 60% of cases no definitive cause can be determined. We found that maternal overweight and obesity increased the risks of childhood epilepsy in a dose-response pattern. (more…)

Author Interviews, Cost of Health Care, JAMA, Surgical Research, Thyroid / 05.04.2017

MedicalResearch.com Interview with: Benjamin James, MD MS Assistant Professor of Surgery Adjunct Assistant Professor of Otolaryngology Section of Endocrine Surgery IU Division of General Surgery Indiana University Hospital Indianapolis, IN 46202 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the few decades, there has been a substantial increase in the incidence of thyroid cancer. It is the fastest growing cancer and a recent study in JAMA found that the mortality rate has been rising. In 2006, Massachusetts passed healthcare reform, which expanded Medicaid, created new subsidized insurance programs for those ineligible for Medicaid and extended young adults eligibility on parental plans until the age of 26. The aim of our study was to evaluate the impact this has had on the treatment of thyroid cancer. To address this question, we used the Hospital Cost and Utilization Project State Inpatient Databases for Massachusetts, New Jersey, New York, and Florida, which included a cohort of 56,581 inpatient admissions from 2001 to 2011. We then compared these states before and after the healthcare reform in Massachusetts to evaluate the effect the healthcare reform had on the treatment of thyroid cancer. (more…)
Author Interviews, Gastrointestinal Disease, JAMA / 04.04.2017

MedicalResearch.com Interview with: Dr. Ann Kurth, Task Force member Dean of the Yale School of Nursing Adjunct professor New York University College of Nursing and the College of Global Public Health. MedicalResearch.com: What is the background for this study? Response: Celiac disease, an immune disorder where people should not eat food with gluten, is fairly prevalent. When people with celiac disease eat foods containing gluten, which is found in wheat, rye and barley, their body responds by inflaming or destroying villi—the tiny, fingerlike projections on the inner lining of the small intestine–which prevents the body from absorbing the necessary nutrients from food.

Author Interviews, Cost of Health Care, JAMA, Macular Degeneration, Ophthalmology, Telemedicine / 02.04.2017

MedicalResearch.com Interview with: John Wittenborn Senior research scientist NORC's Public Health Analytics University of Chicago MedicalResearch.com: What is the background for this study? What are the main findings? Response:The emergence of anti-VEGF treatment for wet-form AMD (choroidal neovascularization) has had a dramatic impact on preserving vision for many Americans. However, community-based studies show that most patients are not diagnosed with wet-form AMD until they have already lost a significant, and largely unrecoverable amount of their vision.  Early detection of wet-form AMD is key to effective treatment and the preservation of vision. The ForeseeHome telemonitoring technology provides patients with a means to check their own eyes on a daily basis to detect the earliest signs of vision loss from wet-form AMD. This is a novel technology that has the potential to improve visual health outcomes for AMD patients.  A prior clinical trial (the AREDS-2 HOME study) demonstrated that this technology can detect wet-form AMD earlier, and with less vision loss than standard care alone. However, that is exactly where that study ended as it reported no cost information nor follow-up. Since the end of this study, the device has been cleared by the FDA and approved for reimbursement by Medicare for certain higher risk patients, but no study has yet considered the long-term implications of adoption of this technology. In our analysis, we use a computer simulation model to essentially estimate what will come next, after patients realize earlier detection of wet-form AMD by utilizing home monitoring. Basically, we follow simulated patients from the time they begin monitoring for the rest of their lives, recording the likely impacts of home monitoring on patients’ long term outcomes including visual status, costs and quality of life. We find that home telemonitoring among the population indicated for reimbursement by Medicare would cost $35,663 per quality adjusted life year (QALY) gained.  Medicare would expect to incur $1,312 in net budgetary costs over 10 years for each patient who initiates monitoring.  However, Medicare patients may expect to achieve lifetime net savings when accounting for the chance of avoided vision loss and its associated costs later in life.

Author Interviews, Breast Cancer, Cancer Research, JAMA, Surgical Research / 31.03.2017

MedicalResearch.com Interview with: Rebecca Nash, MPH Rollins School of Public Health Emory University MedicalResearch.com: What is the background for this study? Response: Contralateral prophylactic mastectomy (CPM) in women with invasive early-stage unilateral breast cancer has significantly increased in the U.S. over the past decade, despite the lack of evidence for a survival benefit. This procedure is particularly common among patients younger than 45 years old. It is also more common in whites compared to blacks, and in privately insured patients compared to uninsured or Medicaid insured patients. However, the extent of regional variation across the United States was unknown. (more…)
