Author Interviews, JAMA, Lipids, Pediatrics / 22.05.2019

MedicalResearch.com Interview with: Amanda Marma Perak, MD, MS Assistant Professor of Pediatrics (Cardiology) and Preventive Medicine MedicalResearch.com: What is the background for this study? Response: Blood cholesterol is a critical initiator of atherosclerotic plaques in the arteries that can lead to heart attack in adulthood. It is well established that these changes in the blood vessels occur already in childhood. Thus, it is important to know the status of cholesterol levels in youth to inform public health efforts aimed at preventing cardiovascular disease in the population. In the US there have been changes in childhood obesity prevalence (which may worsen cholesterol levels), the food supply (such as reduction of trans fats which may improve cholesterol levels), and other factors in recent years. We therefore designed a study to examine trends in cholesterol levels among youth in recent years. (more…)
Author Interviews, Hospital Readmissions, JAMA, Neurology, Outcomes & Safety, University of Pennsylvania / 20.05.2019

MedicalResearch.com Interview with: Sameed Khatana, MD Fellow, Cardiovascular Medicine, Perleman School of Medicine Associate Fellow, Leonard Davis Institute of Health Economics University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: There has been a growing use of quality metrics and indices in the US healthcare system. Much attention has been paid to quality measurement programs used by public payors, however, the use of such programs by commercial payors is much less studied. "Centers of excellence" are one type of quality designation program that is growing in use by commercial payors where certain hospitals are determined to be "high quality" for a certain disease state or procedure based on meeting certain criteria. For some people, this is even impacting the choice of providers and hospitals they can use by payors. We evaluated centers of excellence programs from three large commercial payors, Aetna, Cigna and Blue Cross Blue Shield, targeted at cardiovascular diseases and interventions and examined publicly reported outcomes for all hospitals performing percutaneous coronary interventions (cardiac stenting) in New York State.  (more…)
Author Interviews, Cost of Health Care, Kidney Disease, UCLA / 14.05.2019

MedicalResearch.com Interview with: Chris Childers, MD, PhD Division of General Surgery David Geffen School of Medicine at UCLA Los Angeles, CA 90095 MedicalResearch.com: What is the background for this study? Response: Patients with end-stage renal disease – poorly functioning kidneys – often have to receive dialysis. This typically requires a patient to visit an outpatient clinic several times a week to have their blood filtered by a machine. Over the past few years, two for-profit companies have increased their control over the outpatient dialysis market – DaVita and Fresenius. Combined they control approximately ¾ of the market.  A number of concerns have been raised against these for-profit companies suggesting that the quality of care they deliver may be worse than the care delivered at not-for-profit companies. But, because they control so much of the market and because patients have to receive dialysis so frequently, patients may not have much choice in the clinic they visit. Medicare covers patients who are 65 years or older and also patients on dialysis regardless of age.  Medicare pays a fixed rate for dialysis which they believe is adequate to cover the clinics' costs. However, if a patient also has private insurance, the insurer is required to pay for dialysis instead of Medicare. Whereas Medicare rates are fixed by the federal government, private insurers have to negotiate the price they pay, and may pay much more as a result. (more…)
Author Interviews, Hip Fractures, JAMA, Supplements / 13.05.2019

MedicalResearch.com Interview with: Prof. Haakon E Meyer, PhD Department of Public Health and Global Health Norwegian Institute of Public Health Oslo, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: The use of high dose vitamin supplementation is popular in parts of the population, often without any clear indication and in the absence of clear evidence of benefit. However, side effects can occur, and in a previous published secondary analysis of double blinded randomized controlled trials, we found to our surprise an increased risk of hip fracture in those supplemented with high doses of vitamin B6 in combination with vitamin B12. This finding was re-assessed in the current study employing data from the large observational Nurses' Health Study. As in the previous study, we found that a combined high intake of vitamin B6 and B12 was associated with increased risk of hip fracture. (more…)
Author Interviews, Biomarkers, Cancer Research, Colon Cancer, JAMA, Karolinski Institute / 13.05.2019

MedicalResearch.com Interview with: Louise Olsson MD PhD Senior researcher Department of Molecular Medicine and Surgery Colorectal Surgery Karolinski Institute Stockholm, Sweden  MedicalResearch.com: What is the background for this study? What are the main findings? Response: I read a very interesting paper back in 2006 “Detection and quantification of mutation in the plasma of patients with colorectal cancer”. Only some 60 % of patients with early colorectal cancer were detectable in this way whereas patients with stage IV disease all had a high concentration of APC mutations in their plasma. So the prospects of using the method for example, screening of primary colorectal cancer seemed limited but I thought wow, this is the test to detect recurrences and generalized disease during follow-up after surgery for colorectal cancer. After some discussion we started to collect plasma samples from patients at the hospital where I worked and that´s how my research began. (more…)
Author Interviews, Heart Disease, JAMA, Johns Hopkins, Pulmonary Disease / 07.05.2019

MedicalResearch.com Interview with: Robert A. Wise, M.D. Professor of Medicine Pulmonary and Critical Care Johns Hopkins University School of Medicine Baltimore, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has been a lingering controversy about the safety of long-acting anti-muscarinic agents (LAMA) as maintenance treatment for COPD in patients who have increased cardiovascular risk.  This study enrolled participants with COPD who also had increased cardiovascular risk or known cardiovascular disease.  Participants were randomly treated with either aclidinium bromide (Tudorza Pressair) or placebo. Over 3 years of follow up there was no increased risk of adverse cardiovascular events.  Moreover, the medication had a significant benefit in terms of reducing exacerbations and COPD hospitalizations.

Author Interviews, Cancer Research, Colon Cancer, JAMA / 07.05.2019

MedicalResearch.com Interview with: Prof. Dr. med. Hermann Brenner Clinical Epidemiology and Aging Research Division Head German Cancer Research Center Foundation under Public Law Germany  MedicalResearch.com: What is the background for this study? Response: Colorectal cancer is the third most common cancer globally, accounting for almost 900.000 deaths every year. Most of these deaths could be prevented by screening colonoscopy with early detection and removal of precursors of the cancer. However, capacities and use of screening colonoscopy are limited in most parts of the world, and low-cost but reliable noninvasive screening tests are important alternative primary screening tests. The currently best established noninvasive tests are fecal immunochemical tests for hemoglobin (FITs) which are offered for colorectal cancer screening in an increasing number of countries. Although FITs detect the majority of colorectal cancers they detect approximately one out of four advanced adenomas only, the precursors of most colorectal cancers. We hypothesized that this proportion could be increased by taking a single pill of aspirin two days prior to collecting the stool sample for FIT, because the well-established antithrombotic effects of aspirin might favor detecting occult bleeding from colorectal cancer or its precursors.

Author Interviews, Brigham & Women's - Harvard, JAMA, Pediatrics, Weight Research / 26.04.2019

MedicalResearch.com Interview with: Vincent W. V. Jaddoe, MD, PhD Adjunct Professor of Epidemiology Department of Epidemiology MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Childhood body fat may be affected by patterns of fetal and infant weight change. Children born small for gestational age (SGA) tend to have infant growth acceleration, whereas those born large for gestational age (LGA) tend to have infant growth deceleration. Little is known about fetal and infant growth patterns affecting visceral, liver, and pericardial fat, which are strongly associated with cardiometabolic disease in later life. We assessed in a large population cohort study whether fetal and infant weight change was associated with not only general, but also organ fat at school age. We observed that fetal and infant weight change patterns were both associated with childhood body fat, but weight change patterns in infancy tended to have larger effects. Fetal growth restriction followed by infant growth acceleration was associated with increased visceral and liver fat.  (more…)
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, Cancer Research, JAMA, Pain Research / 19.04.2019

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, Opiods / 09.04.2019

MedicalResearch.com Interview with: Joanne Spetz, PhD Professor Philip R. Lee Institute for Health Policy Studies San Francisco, CA 94143-0936  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Medication treatment is an important component of treatment for opioid use disorder. Buprenorphine has been the focus of policies designed to increase access to treatment and is the most widely-used medication due to well-established evidence of its efficacy and its accessibility outside licensed narcotics treatment programs. The most common brand name for this medication is Suboxone. There is a shortage of providers authorized to prescribe it, in part because only physicians were permitted to obtain waivers from the Drug Enforcement Agency to prescribe it outside of licensed narcotics treatment programs until the opioid bill of 2016. That bill granted nurse practitioners (NPs) and physician assistants (PAs) the ability to apply for waivers. However, in states that require NPs and/or PAs to be supervised by or collaborate with a physician, there are additional requirements regarding the training of the physician before the NP or PA can apply for a waiver. This affects nearly half of states for NPs, and all states for PAs. We found that the average percentage of NPs with waivers was 5.6% in states that do not require physician supervision, but only 2.4% in more restrictive states. Even after adjusting for other factors, we found that the percentage of NPs with waivers was 75% higher when physician oversight is not required. We didn’t find a similar result for PAs, probably because they must have physician oversight in all states.  (more…)
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…)
Author Interviews, Brigham & Women's - Harvard, Flu - Influenza, Heart Disease, JAMA / 27.03.2019

MedicalResearch.com Interview with: Sonja Kytomaa MA Research Associate Brigham and Women’s Hospital Scott D. Solomon, MD The Edward D. Frohlich Distinguished Chair Professor of Medicine Harvard Medical School Senior Physician Brigham and Women’s Hospital International Associate Editor, European Heart Journal   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Influenza is associated with an increased risk of cardiovascular events, yet few studies have explored the temporal association between influenza activity and hospitalizations, especially due to heart failure (HF). Our aim with this study was to explore the temporal association between influenza activity and hospitalizations for HF and myocardial infarction (MI) in the general population. We related the number of MI and HF hospitalizations by month, which were sampled from 4 US communities and adjudicated in the surveillance component of the Atherosclerosis Risk in Communities (ARIC) study, to monthly influenza-like illness activity, as reported by the Centers for Disease Control and Prevention. We found that a 5% increase in influenza activity was associated with a 24% increase in HF hospitalizations rates, while overall influenza was not significantly associated with MI hospitalizations. Influenza activity in the months before hospitalization was not associated with either outcome. (more…)
Author Interviews, JAMA, Karolinski Institute, Pediatrics / 26.03.2019

MedicalResearch.com Interview with: Mikael Norman, MD, PhD, Professor Karolinska Institutet & Karolinska University Hospital Stockholm, Sweden  MedicalResearch.com: What is the background for this study? Response: So far, preterm birth has been difficult to predict and prevent. In particular, extremely preterm birth has continued to be an issue in terms of optimal care before and after birth, costs and long term health outcomes. Therefore, studies on how the management and outcome varies over time in these patients are important. (more…)
Author Interviews, Heart Disease, JAMA, Stem Cells / 26.03.2019

MedicalResearch.com Interview with: Annetine C. Gelijns, PhD Professor and System Chair Population Health Science and Policy Icahn School of Medicine at Mount Sinai Alan J Moskowitz, MD Professor of Population Health Science and Policy Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Where do these mesenchymal cells come from?  Response: Implantable LVADs significantly improve the survival and quality of life of advanced heart failure patients. However, these devices are associated with substantial adverse events, including infection and thromboembolic events. Moreover, whereas these devices improve myocardial function, few patients recover sufficient function to be explanted from their LVAD. These observations have focused attention on stem cells as a possible adjunctive therapy to further augment cardiac recovery. Mesenchymal precursor cells (MPCs), which are obtained from healthy donors and culture-expanded, have been shown in animal and early human studies to improve cardiac function. Using temporary weaning as a signal of cardiac recovery, we conducted an exploratory trial in the Cardiothoracic Surgical Trials Network (CTSN), which found that MPCs increased the probability of temporary weaning from full LVAD support compared to sham-control patients. Therefore, this signal of efficacy led the CTSN to design our current follow-up trial evaluating the efficacy and safety of a higher dose of MPCs in LVAD patients. (more…)

MedicalResearch.com Interview with: Alexander A. Leung, MD, MPH Department of Community Health Sciences Department of Medicine University of Calgary Calgary, Alberta, Canada MedicalResearch.com: What is the background for this study? Response: The 2017 American College of Cardiology and American Heart Association (ACC/AHA) blood pressure guidelines redefined hypertension according to a blood pressure cutoff of ≥130/80 mm Hg, compared to the traditional cutoff of ≥140/90 mm Hg.

Asthma, Author Interviews, JAMA, OBGYNE, Pediatrics, Vitamin D / 12.03.2019

MedicalResearch.com Interview with: Bo Chawes, MD, PhD, DMSc Associate Professor C‌openhagen Prospective Studies on Asthma in Childhood H‌erlev and G‌entofte H‌ospital U‌niversity of C‌openhagen MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has been a global surge in vitamin D deficiency happening in parallel with an increase in prevalence of childhood asthma, which suggests that low maternal vitamin D levels during pregnancy may increase asthma risk in the child. Due to that we conducted a randomized double-blinded controlled trial within the Danish COPSAC2010 cohort (www.copsac.com) of 7-fold (2,800 IU/d) vs. standard dose (400 IU/d) of vitamin D supplementation from pregnancy week 24 aiming to reduce offspring asthma risk. At age 3, we observed a non-significant 24% reduced risk of recurrent asthma-like symptoms, ie. recurrent wheeze, in the high-dose vitamin D group. In the current study, we followed 545 of the 581 children in the study till age 6, where an asthma diagnosis can be established and observed no effect of the high-dose vitamin D supplement on the child's risk of asthma.  (more…)
Author Interviews, Brigham & Women's - Harvard, Critical Care - Intensive Care - ICUs, Infections, JAMA / 12.03.2019

MedicalResearch.com Interview with: Chanu Rhee, MD,MPH Assistant Professor of Population Medicine Harvard Medical School / Harvard Pilgrim Health Care Institute Assistant Hospital Epidemiologist Brigham and Women’s Hospital  MedicalResearch.com: What is the background for this study? Response: Sepsis is the body’s reaction to a serious infection that results a cascade of inflammation in the body and organ dysfunction, such as low blood pressure, confusion, or failure of the lungs, kidneys, or liver.   Sepsis is a major cause of death, disability, and cost in the U.S. and around the world.  Growing recognition of this problem has led to numerous sepsis performance improvement initiatives in hospitals around the country.  Some of these efforts have also been catalyzed by high-profile tragic cases of missed sepsis leading to death, which may have contributed to a perception that most sepsis deaths are preventable if doctors and hospitals were only better at recognizing it. However, the extent to which sepsis-related deaths might be preventable with better hospital-based care is unknown.  In my own experience as a critical care physician, a lot of sepsis patients we treat are extremely sick and even when they receive timely and optimal medical care, many do not survive.  This led myself and my colleagues to conduct this study to better understand what types of patients are dying from sepsis and how preventable these deaths might be.  (more…)
Author Interviews, Depression, Nutrition, Supplements, Weight Research / 08.03.2019

MedicalResearch.com Interview with: Prof. Marjolein Visser PhD Professor of Healthy Aging Head section Nutrition and Health Department of Health Sciences, Vrije Universiteit Amsterdam Amsterdam Public Health research institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: More than 40 million Europeans experience a major depressive disorder. One in ten men, and one in five women suffer from clinical depression at least once during their lifetime. Depression is one of the most prevalent and disabling disorders in the EU. Given the increasing prevalence of depression, more people are actively searching for ways to decrease their risk through lifestyle modification, but are often overwhelmed by confusing and contradictory information. The MooDFOOD prevention trial is the largest randomized clinical trial to study the effects of nutritional strategies on the prevention of major depressive disorder. Over 1000 overweight or obese participants identified as being at elevated risk for depression but who were not currently depressed, from four European countries -the Netherlands, the United Kingdom, Germany and Spain, took part in the study. Participants were randomized to either take nutritional supplements containing folic acid, vitamin D, zinc, selenium or to a pill placebo, and half of participants also received a behavioral lifestyle intervention intended to change dietary behaviors and patterns.

Author Interviews, FDA, JAMA / 06.03.2019

MedicalResearch.com Interview with: Craig Alexander Garmendia, PhD Office of Bioresearch Monitoring Operations Office of Regulatory Affairs US Food and Drug Administration Miami, Florida MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Clinical trials under the U.S. Food and Drug Administration’s (FDA) purview have been shown to suffer from falsified data. While the FDA warns researchers when falsified data are discovered, these data still make their way into medical literature. In this novel study, Dr. Garmendia and colleagues conducted a systematic review to examine the effects of publications containing falsified data on meta-analyses using sensitivity analyses. Almost half of all meta-analyses had conclusions altered by publications containing falsified data, while nearly one-third of all analyses had considerable changes in outcomes. (more…)
Author Interviews, Diabetes, Exercise - Fitness, JAMA, Lifestyle & Health, Weight Research / 05.03.2019

MedicalResearch.com Interview with: Giuseppe Pugliese, MD, PhD for the Italian Diabetes and Exercise Study 2 (IDES_2) Investigators Department of Clinical and Molecular Medicine ‘‘La Sapienza’’ University Diabetes Unit, Sant’Andrea University Hospital Rome, Italy MedicalResearch.com: What is the background for this study? Response: There is a growing epidemic of obesity and type 2 diabetes worldwide, which are causally related to the increasing prevalence of “physical inactivity”, i.e., an insufficient amount of moderate-to-vigorous physical activity according to current guidelines, and “sedentariness”, i.e., too many hours, especially if uninterrupted, spent in a sitting or reclined position.  These two unhealthy behaviors exert their detrimental effects independently of each other and are very common among people suffering from type 2 diabetes, who would therefore benefit from increasing physical activity and reducing sedentary time, as recommended by current guidelines. However, such a behavior change is generally difficult for a number of internal and external barriers and requires behavioral interventions targeting both physical activity and sedentary habits.  Unfortunately, there is no definitive evidence that this is indeed feasible and, particularly, that, if adopted, change in behavior can be maintained in the long term.  (more…)

MedicalResearch.com Interview with: Sarah Parish, MSc, DPhil Professor of Medical Statistics and Epidemiology MRC Population Health Research Unit Nuffield Department of Population Health University of Oxford MedicalResearch.com: What is the background for this study? Response: Acquiring reliable randomized evidence of the effects of cardiovascular interventions on cognitive decline is a priority. In this secondary analysis of 3 randomized intervention trials of cardiovascular event prevention, including 45 029 participants undergoing cognitive testing, we estimated the association of the avoidance of vascular events with differences in cognitive function in order to understand whether reports of non-significant results exclude worthwhile benefit.  (more…)

MedicalResearch.com Interview with: Martin C. Tammemägi PhD Senior Scientist Cancer Care Ontario | Prevention & Cancer Control Scientific Lead Lung Cancer Screening Pilot for People at High Risk Professor (Epidemiology) | Brock University Department of Health Sciences Ontario, Canada MedicalResearch.com: What is the background for this study? Response: Some prediction models can accurately predict lung cancer risk (probability of developing lung cancer during a specified time). Good model predictors include sociodemographic, medical and exposure variables. In recent years, low dose computed tomography (LDCT) lung cancer screening has become widespread in trials, pilots, demonstration studies, and public health practice. It appears that screening results provides added valuable, independent predictive information regarding future lung cancer risk, aside from the lung cancers directly detected from the diagnostic investigations resulting from positive screens.

MedicalResearch.com Interview with: Mr. Tim Badgery-Parker ELS, BSc(Hons), MBiostat Research Fellow,Value in Health Care Division Menzies Centre for Health Policy MedicalResearch.com: What is the background for this study? Response: This is part of a large program of work at the Menzies Centre for Health Policy on low-value care in the Australian health system. We have previously published rates of low-value care in public hospitals in Australia’s most populous state, New South Wales, and a report on rates in the Australian private health insurance population is due for publication shortly. We have also done similar analyses for other Australian state health systems. This particular paper extends the basic measurement work to focus on what we call the ‘cascade’ effects. That is, looking beyond how much low-value care occurs to examine the consequence for patients and the health system of providing these low-value procedures. (more…)

MedicalResearch.com Interview with: Jari Tiihonen, MD, PhD Professor, Department of Clinical Neuroscience Karolinska Institutet Stockholm, Sweden  MedicalResearch.com: What is the background for this study? Response: The effectiveness of antipsychotic combination therapy in schizophrenia relapse prevention is controversial, and use of multiple agents is generally believed to impair physical well-being. But the evidence for this are weak and antipsychotic polypharmacy is widely used. (more…)
Author Interviews, Health Care Systems, JAMA, Outcomes & Safety, Surgical Research / 22.02.2019

MedicalResearch.com Interview with: Alexis G. Antunez MS University of Michigan Medical School, Ann Arbor Center for Healthcare Outcomes and Policy University of Michigan, Ann Arbor MedicalResearch.com: What is the background for this study? Response: The American College of Surgeons Commission on Cancer is implementing a National Accreditation Program for Rectal Cancer (NAPRC), aiming to improve and standardize the quality of rectal cancer care in the United States. While this is a commendable goal, previous accreditation programs in other specialties have faced controversy around their uncertain impact on access to care. Furthermore, it is well established that the quality of rectal cancer care is associated with patients’ socioeconomic position. So, the NAPRC could have the unintended consequence of widening disparities and limiting access to high quality rectal cancer care for certain patient populations.  (more…)
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.

Author Interviews, Mammograms / 06.02.2019

MedicalResearch.com Interview with: "Kiki Gets a Mammogram" by kristiewells is licensed under CC BY-NC-SA 2.0. To view a copy of this license, visit: https://creativecommons.org/licenses/by-nc-sa/2.0Philippe Henrot, MD Radiology Department Institut de Cancerologie de Lorraine Vandoeuvre-les-Nancy  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The initial observation was that daily practice of mammography shows a substantial proportion of women that report a negative experience after having a mammogram. Compression of the breast before delivering X-rays is mandatory to achieve the best image quality and to detect small cancers. Unfortunately, compression is uncomfortable, even sometimes painful. We took into consideration a study of PJ Kornguth et al. published in 1993 reporting the self-compression technique. In this study one breast was compressed by the radiographer and the other with self-compression. The author reported a high level of patient satisfaction, and a lower discomfort, without compromising image quality. We performed a multicenter prospective randomized trial to demonstrate the feasibility of the self-compression technique in condition similar to routine screening or follow-up, compared with standard compression. The primary outcome was to demonstrate that self-compression did not lead to compress the breast less than standard compression, and that was done. The secondary outcomes were to evaluate pain, compression force and image quality. The results indicated that compression force was higher when the women controlled themselves the compression of their breast, and the pain measured on a visual analogue scale was lower. Moreover, image quality was not compromised compared with standard compression.  (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.
