MedicalResearch.com Interview with: Heikki Joensuu, MD Department of Oncology Helsinki University Hospital University of Helsinki Helsinki, Finland  MedicalResearch.com: What is the background for this study? Response: The randomized Scandinavian Sarcoma Group (SSG) XVIII trial compared three years of adjuvant imatinib to one year of adjuvant imatinib as adjuvant treatments of patients who had undergone macroscopically complete surgery for a GIST with a high risk for tumor recurrence. In this trial, patients treated with 3 years of imatinib had improved overall survival as compared to those who were allocated to one year of adjuvant imatinib. In 2 other randomized trials that compared either 1 year of adjuvant imatinib to one year or placebo, or 2 years of adjuvant imatinib to observation, no improvement in overall survival was found, although in all three trials adjuvant imatinib improved recurrence-free survival (RFS). The reasons for the discrepant findings with respect of overall survival in the 3 trials have been unclear. (more…)
Author Interviews, Clots - Coagulation, Electronic Records, JAMA, NYU, Surgical Research / 23.03.2017

MedicalResearch.com Interview with: Zachary Borabm, Research fellow Hansjörg Wyss Department of Plastic Surgery NYU Langone Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent studies have shown that health care providers perform poorly in risk stratifying their patients for venous thromboembolism (VTE) which leads to inadequate VTE prophylaxis delivery, especially in surgical patients. Computerized Clinical Decision Support Systems (CCDSSs) are programs integrated into an electronic health record that have the power to aid health care providers. Using a meta-analysis study technique we were able to pool data from 11 studies, including 156,366 patients that either had CCDSSs intervention or routine care without CCDSSs. Our main outcome measures were the rate of prophylaxis for VTE and the rate of actual VTE events. We found that CCDSSs increased the rate of VTE prophylaxis (odds ratio 2.35, p<0.001) and decreased the risk of VTE events (risk ratio 0.78, p<0.001). (more…)
Abuse and Neglect, Author Interviews, Diabetes, JAMA, Ophthalmology, Technology / 21.03.2017

MedicalResearch.com Interview with: José Cunha-Vaz, M.D., Ph.D. Emeritus Professor of Ophthalmology University of Coimbra, Portugal President of AIBILI Association for Innovation and Biomedical Research on Light and Image Editor-in-Chief of Ophthalmic Research Coordinator, Diabetic Retinopathy and Retinal Vascular Diseases, European Vision Institute Clinical Research Network (EVICR.net)  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this study, we evaluated the clinical utility of quantitative measures of microvasculature in optical coherence tomographic angiography (OCTA). Although several studies have demonstrated the potential value of measures of microvasculature in the management of diabetic retinopathy (DR), our study uses the ROC curve to compare the overall value of different approaches. In this age matched population with a range of disease, the mean vessel density measured in the SRL had the highest AUC, indicating that it is best among the methods tested at differentiating normal eyes from eyes with diabetic retinopathy.

Aging, Alzheimer's - Dementia, Author Interviews, JAMA, Supplements / 21.03.2017

MedicalResearch.com Interview with: Richard J. Kryscio, Ph.D. Statistics and Chair, Biostatistics and Sanders-Brown Center on Aging Sanders-Brown Center on Aging University of Kentucky  MedicalResearch.com: What is the background for this study? Response: At the time the trial was initiated (2002), there was ample evidence that oxidative stress is an important mechanism in brain aging. Research showed that protein oxidation is linked to the brain’s response to the abnormal proteins seen in Alzheimer disease (amyloid beta plaques in particular) leading to inflammation, DNA repair problems, reduced energy production, and other cellular changes that are identified mechanisms in the Alzheimer brain. Both vitamin E and selenium are antioxidants. Antioxidants, either through food or supplements, are believed to reduce oxidative stress throughout the body. In the brain, they may reduce the formation of amyloid beta plaques, reduce brain inflammation, and improve other brain processes. Studies in humans support these hypotheses. The Rotterdam study in the Netherlands, as an example, showed that initial blood levels of vitamin E could predict dementia risk. Those people with higher vitamin E levels were 25% less likely to develop dementia. Also, selenium deficiency results in cognitive difficulties and several population-based studies have shown an association between selenium level and cognitive decline (lower selenium levels are linked to thinking changes in the elderly).

Author Interviews, Heart Disease, JAMA / 21.03.2017

MedicalResearch.com Interview with: Eric A. Secemsky, MD, MSc Interventional Cardiology Fellow Massachusetts General Hospital Harvard Medical School Baim Institute for Clinical Research  MedicalResearch.com: What is the background for this study?  What are the main findings? Response: We know from previous trials that continuing dual antiplatelet therapy longer than 12 months after coronary stenting decreases ischemic events, including spontaneous myocardial infarction and stent thrombosis. However, extending dual antiplatelet therapy is also associated with some increase in bleeding risk. For instance, in the DAPT Study, more than 25,600 patients were enrolled and received both aspirin and a thienopyridine antiplatelet drug (clopidogrel or prasugrel) for one year after stenting. Of these patients, 11,648 participants who had followed the study protocol and had no serious cardiovascular or bleeding events during that first year were then randomized to either continue with dual therapy or to receive aspirin plus a placebo for another 18 months. The overall findings of the DAPT study were that, compared with switching to aspirin only after one year, continuing dual antiplatelet therapy for a total of 30 months led to a 1.6 percent reduction in major adverse cardiovascular and cerebrovascular events – a composite of death, myocardial infarction, stent thrombosis and ischemic stroke – and a 0.9 percent increase in moderate to severe bleeding events. The prognosis following early ischemic and bleeding events has previously been well described. However, data for events occurring beyond 1 year after PCI are limited. As such, we sought to assess the cumulative incidence of death following ischemic and bleeding events occurring among patients in the DAPT Study beyond 1 year after coronary stenting. (more…)
Author Interviews, JAMA, Mental Health Research, Urology / 21.03.2017

MedicalResearch.com Interview with: Blayne Welk, MD, FRCSC Assistant Professor of Surgery Western University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Concerns have been raised by regulatory agencies and patients about possible serious psychiatric side effects associated with the use of 5 alpha reductase inhibitors. These medications can be used for both enlarged prostates and alopecia. We used administrative data to assess for potential psychiatric side effects associated with finasteride and dutasteride usage in older men with benign prostatic enlargement. In our study we found that there was no increased risk of suicide associated with the use of these medications. However, there was a small increase in both self-harm and new onset depression associated with the use of 5 alpha reductase inhibitors. (more…)
Author Interviews, JAMA, Mental Health Research / 19.03.2017

MedicalResearch.com Interview with: Florian Walter MSc Centre for Mental Health and Safety University of Manchester, Manchester, England Dr Roger Webb PhD and Reader in Mental Health Epidemiology Senior Postgraduate Research Tutor Division of Psychology and Mental Health Faculty of Biology, Medicine and Health The University of Manchester MedicalResearch.com: What is the background for this study? Response: Mental disorders are associated with an elevated risk of premature mortality, and risk is especially heightened soon after discharge from inpatient psychiatric services. Previous studies have focused on single causes of death, whereas our study considered a comprehensive array of cause-specific mortality outcomes. We analysed over 1.7 million Danish residents in our national interlinked registry study, which was conducted collaboratively by the Centre of Mental Health and Safety, University of Manchester, UK and the National Centre for Register-based Research, Aarhus University, Denmark. We compared the risk of dying from specific natural and unnatural causes of death among patients following their first discharge from inpatient psychiatric care versus people not admitted. (more…)
Author Interviews, Exercise - Fitness, Genetic Research, Heart Disease, JAMA, University of Michigan / 19.03.2017

MedicalResearch.com Interview with: Sara Saberi, MD Assistant Professor Inherited Cardiomyopathy Program Frankel Cardiovascular Center University of Michigan Hospital and Health Systems  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Patients with hypertrophic cardiomyopathy are often told not to exercise or to significantly curb their exercise due to concern over the potential risk of increased ventricular arrhythmias and sudden cardiac death. There is no data regarding risks/benefits of exercise in HCM though. There is, however, data that shows that patients with HCM are less active and more obese than the general population AND a majority feel that exercise restrictions negatively impact their emotional well-being. So, we devised a randomized clinical trial of a 16-week moderate-intensity aerobic exercise program versus usual activity with the primary outcome being change in peak VO2 (oxygen consumption). This exercise intervention resulted in a 1.27 mL/kg/min improvement in peak VO2 over the usual activity group, a statistically significant finding. There were no major adverse events (no death, aborted sudden cardiac death, appropriate ICD therapies, or sustained ventricular tachycardia). There was also a 10% improvement in quality of life as measured by the Physical Functioning scale of the SF-36v2. (more…)
Author Interviews, Dermatology, JAMA / 17.03.2017

MedicalResearch.com Interview with: Dr. Alex M. Glazer MD National Society for Cutaneous Medicine New York, New York  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We had previously studied the geographic distribution of dermatologists throughout the United States which revealed that dermatologists are unevenly geographically distributed throughout the country, with many regions having fewer than the 4 providers per 100,000 people needed to adequately care for a population. Because of the influx of PAs and NPs into the healthcare workforce throughout the past decade, we wanted to see how these providers were supplementing dermatologic care. The main finding of our study is that dermatology PAs are helping to supplement dermatologists and together are providing broader, more uniform coverage across the United States (more…)
Author Interviews, ENT, JAMA, Johns Hopkins, Surgical Research / 16.03.2017

MedicalResearch.com Interview with: Lisa E. Ishii, MD, MHS Associate Professor of Otolaryngology - Head and Neck Surgery John Hopkins Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: There was a gap in our knowledge about what the average lay person thought about the impact of a facelift. We had information about what experts in the field like Dr. Swail thought, and some about what patients themselves thought, but nothing about lay people. Patients who choose to have a facelift are typically concerned about the opinions of: 1) Themselves when they look in the mirror, and 2) Laypeople they encounter socially in society. Our study showed for the first time that laypeople find people who have had a facelift to appear more attractive, more youthful, healthier and more successful than they were before their facelift.

Author Interviews, CDC, Dermatology, Education, Environmental Risks, JAMA / 16.03.2017

MedicalResearch.com Interview with: Sherry Everett Jones PhD, MPH, JD, FASHA Health Scientist, Division of Adolescent School Health Centers for Disease Control & Prevention MedicalResearch.com: What is the background for this study? What are the main findings? Response: Skin cancer is the most common form of cancer in the United States. Results from the School Health Policies and Practices Study found that in 2014, most schools lacked practices that could protect children and adolescents from sun exposure while at school. Positive attitudes and beliefs about sun safety behavior, which would make such behavior more likely, can be promoted and supported by school system policies and practices. (more…)
Author Interviews, Gender Differences, JAMA / 15.03.2017

MedicalResearch.com Interview with: David A. Klein, MD, MPH Uniformed Services University of the Health Sciences (USUHS) Bethesda, Maryland Fort Belvoir Community Hospital (FBCH), Fort Belvoir, Virginia MedicalResearch.com: What is the background for this study? What are the main findings? Response: In June 2016, the ban was lifted on transgender personnel serving openly in the military. Research suggests approximately 200 active-duty service members may request a gender transition annually. The purpose of this study is to determine military family physician readiness to care for such patients. The majority (74 percent) of physicians have not received any formal education on the treatment of patients with gender dysphoria. Almost half of surveyed physicians are willing to prescribe cross-hormone therapy; of these, 99 percent report the need for additional training and/or assistance to do so. 53 report an unwillingness to prescribe even with additional education and assistance.

Author Interviews, JAMA, Orthopedics / 14.03.2017

MedicalResearch.com Interview with: Justine M. Naylor, PhD Braeside Hospital, HammondCare, Australia South West Sydney Clinical School, University of New South Wales, Liverpool Hospital South West Sydney Local Health District, Liverpool 2170, NSW, Australia MedicalResearch.com: What is the background for this study? Response: Total knee arthroplasty (replacement) for end-stage arthritis is a very successful procedure for relieving the associated pain and functional impairments. Formalized rehabilitation following the surgery is also considered an essential adjunct to optimise recovery. World-wide, the volume of knee arthroplasty surgeries is increasing each year. In the US, for example, the prevalence of this surgery increased 11-fold from 1980 to 2010. The costs of the procedures (including the acute and rehabilitation costs) are also increasing. Because of these trends, there is concern for the future sustainability of these procedures. Research devoted to identifying the most cost-effective strategies in this field is required. Our group conducted a randomized trial comparing 10-days of inpatient rehabilitation to a simple, clinician-monitored home program in people who underwent total knee arthroplasty for end-stage osteoarthritis. Inpatient rehabilitation in a rehabilitation facility is commonly provided after knee arthroplasty in various countries including Australia, the US and Switzerland, and is comparatively expensive. In particular, it is a commonly available option for people with private healthcare insurance. Essentially, we wanted to compare 2 extremes – a resource-intensive program to one with far less resource requirements. Because patients who experience complications immediately after surgery may require inpatient rehabilitation to aid their recovery, we only included patients who did not experience a significant complication while in hospital, thus, were otherwise deemed able to be discharged directly home.

Author Interviews, Heart Disease, JAMA, Stroke / 14.03.2017

MedicalResearch.com Interview with: Dr. Ying Xian MD PhD Department of Neurology, Duke Clinical Research Institute Duke University Medical Center Durham, North Carolina MedicalResearch.com: What is the background for this study? Response: Atrial fibrillation (AF) is the most common arrhythmia. AF increases the risk for stroke and accounts for 10% to 15% of all ischemic strokes. While the burden of AF-related stroke is high, AF is a potentially treatable risk factor. Numerous studies have demonstrated that vitamin K antagonists, such as warfarin, or non-vitamin K antagonist oral anticoagulants (NOACs), reduce the risk of ischemic stroke. Based on these data, current guidelines recommend adjusted-dose warfarin or NOACs over aspirin for stroke prevention in high-risk patients with Atrial fibrillation. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA / 13.03.2017

MedicalResearch.com Interview with: Yusuke Tsugawa, research associate Department of Health Policy and Management Harvard T H Chan School of Public Division of General Internal Medicine and Primary Care Brigham and Women’s Hospital, Boston, MA      MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well known that health spending varies substantially across geographical regions, and yet regions that spend more on health care dot not achieve better health outcomes. These findings has led to many to conclude that at least 20% of U.S. health care spending could be reduced without compromising quality of care. However, while physicians play a critical role in health care decision making, little is known as to how much health care spending varies between physicians, and its implications for patient outcomes. In this study, we found that the variation in spending across physicians is slightly larger than the variation across hospitals. More importantly, higher spending by physicians did not lead to lower patient mortality or readmission rates, within the same hospital. (more…)
Author Interviews, Dermatology, JAMA, Race/Ethnic Diversity, Transplantation / 10.03.2017

MedicalResearch.com Interview with: Christina Lee Chung, MD, FAAD Associate Professor of Dermatology Director, Center for Transplant Patients Drexel University College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: It’s long been recognized immunosuppressed organ transplant recipients are at significantly increased risk for skin cancer and other types of skin disease. But despite advances to improve skin cancer prevention for these patients, little is known about how skin conditions affect African-American, Asian and Hispanic transplant recipients. This is problematic given that, according to the U.S. Department of Health and Human Services, more than half of the 120,000 Americans on the waiting list for organs identify as nonwhite. We compared medical records of 412 organ transplant recipients — including 154 white patients and 258 nonwhite (black, Asian or Hispanic) — who were referred to the Drexel Dermatology Center for Transplant Patients between 2011 and 2016. As one of the only models of its kind in the country, the center provides post-transplant dermatological care to every patient who is transplanted by and/or followed by the Drexel University and Hahnemann University Hospital Transplant Programs. That means that every patient, regardless of race, is screened annually for skin cancer, which provided a unique dataset for us to analyze. Two hundred eighty-nine transplant recipients exhibited malignant, infectious or inflammatory conditions during their evaluation, but their primary acute diagnoses differed greatly by race. In 82 white patients, skin cancer was the most common acute problem requiring attention at first visit. Black and Hispanic patients, by contrast, were most often diagnosed with inflammatory or infectious processes, such as fungal infections, warts, eczema, psoriasis, and rashes that required immediate medical attention. Overall, squamous cell carcinoma in situ was the most common type of skin cancer diagnosed in each racial or ethnic group. But the location of the cancerous lesions again depended on the race of the patient. Most lesions in white and Asian patients occurred in sun-exposed areas of the body, like the scalp, neck, chest and back. For black patients, the lesions were primarily found in the groin.  Moreover, six of the nine lesions found on black patients tested positive for high-risk HPV strains, suggesting an association between the virus and skin cancer for African Americans. We also provided questionnaires to 66 organ transplant recipients to find out more about the patients’ awareness of skin cancer prevention. Seventy-seven percent of white patients were aware their skin cancer risk was increased, compared to 68 percent of nonwhites. Only 11 percent of nonwhite patients reported having regular dermatologic examinations, compared to 36 percent of whites. Finally, 45 percent of white patients but only 25 percent of nonwhite reported knowing the signs of skin cancer. (more…)

Allergies, Asthma, Author Interviews, JAMA, Pediatrics / 09.03.2017

MedicalResearch.com Interview with: Elizabeth C. Matsui, MD MHS Professor of Pediatrics, Epidemiology, and Environmental Health Sciences Johns Hopkins University Baltimore, MD 21287  MedicalResearch.com: What is the background for this study? Response: We designed this study after our previous work indicated that mouse allergy was common among low-income children living in some urban neighborhoods in the US, that these children also had high levels of mouse allergen exposure in their homes, and that children who are both allergic to mice and exposed to high levels of mouse allergen are at greater risk of asthma symptoms, emergency room visits and hospitalization.   Given this background, we designed a randomized clinical trial to determine if an intensive professionally delivered mouse intervention was better than education about mouse control in reducing asthma symptoms and lowering home mouse allergen levels.

Author Interviews, JAMA, Sugar / 08.03.2017

MedicalResearch.com Interview with: Marlene B. Schwartz PhD Director, Rudd Center for Obesity & Food Policy (Principal Investigator) Professor, Department of Human Development and Family Studies University of Connecticut Hartford, CT 06103 MedicalResearch.com: What is the background for this study?  Response: The aim of this study was to evaluate the impact of a community-wide campaign to reduce consumption of sugary beverages in Howard County, Maryland. We measured the retail sales of sugary drinks in supermarkets in the target community and a set of matched control supermarkets in another state. The campaign included multiple components over three years, including television advertising, digital marketing, direct mail, outdoor advertising, social media and earned media, creating 17 million impressions. The community partners successfully advocated for public policies to encourage healthy beverage consumption in schools, child care, health care and government settings. (more…)
Author Interviews, JAMA, Pain Research, Stroke / 08.03.2017

MedicalResearch.com Interview with: Alessandro Pezzini, MD, FESO Professore Associato di Neurologia Dipartimento di Scienze Cliniche e Sperimentali Clinica Neurologica Università degli Studi di Brescia Italia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Scarce reports have suggested that a relation might exist between migraine and cervical artery dissection (CEAD), the most frequent cause of ischemic stroke in young adults in Western countries. However, data available so far were obtained from few studies conducted on small cohorts of patients, which limits the generalizability of their findings. In our study we analysed the data from the Italian Project on Stroke in Young Adults (IPSYS) project, one of the largest registries of young ischemic stroke patients, and observed that migraine, especially the subtype without aura was strongly and independently associated to CEAD. This seems particularly true for men and for people younger than 39 years. (more…)
Author Interviews, CDC, Dermatology, Environmental Risks, JAMA, Melanoma / 07.03.2017

MedicalResearch.com Interview with: Gery P. Guy Jr., PhD, MPH Senior Health Economist Division of Unintentional Injury CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: The incidence of skin cancer is increasing in the United States, and individuals who indoor tan are at an increased risk of skin cancer. Treating skin cancer costs $8.1 billion annually. The number of high school students who indoor tan dropped by half from 2009 to 2015. In 2015, 1.2 million high school students indoor tanned, down from 2.5 million in 2009. This is a much bigger decrease than we have seen in the past and is an encouraging finding. We also found that 82% of indoor tanners reported sunburn in the past year compared with 54% of those who did not engage in indoor tanning. (more…)
Author Interviews, Dermatology, Global Health, JAMA / 07.03.2017

MedicalResearch.com Interview with: Chante Karimkhani, MD University Hospitals Case Western Medical Center, Cleveland, Ohio now with Department of Dermatology University of Colorado, Denver MedicalResearch.com: What is the background for this study? What are the main findings? Response: Ranging from benign inflammatory to infectious, autoimmune, and malignant conditions, skin diseases cause significant disfigurement, pain, and psychological morbidity. The Global Burden of Disease (GBD) Study 2013 is a large-scale epidemiological assessment of burden from 306 diseases in 195 countries, both sexes, and 14 age groups. Disease burden is measured by combining morbidity and mortality into a single metric of disability-adjusted life years (DALYs), where one DALY is equivalent to one year of healthy life lost. Skin diseases contributed 1.79% of the total global burden from all diseases. The skin diseases arranged in order of decreasing global DALYs are: dermatitis (atopic, contact, seborrheic), acne vulgaris, urticaria, psoriasis, viral skin diseases, fungal skin diseases, fungal skin diseases, scabies, melanoma, pyoderma, cellulitis, keratinocyte carcinoma (basal and squamous cell carcinomas), decubitus ulcer, and alopecia areata. Younger populations had the greatest burden from infectious skin conditions, while acne caused the greatest burden in the second and third decades of life. Elderly populations had the greatest DALY rates from melanoma and keratinocyte carcinoma. Skin conditions also exhibit distinct geographical patterns of disease burden. (more…)
Author Interviews, Education, JAMA, Race/Ethnic Diversity, Yale / 06.03.2017

MedicalResearch.com Interview with: Dowin Boatright, MD, MBA Department of Emergency Medicine Yale School of Medicine New Haven, Connecticut Fellow, Robert Wood Johnson Clinical Scholars Program Veterans Affairs Scholar MedicalResearch.com: What is the background for this study? What are the main findings? Response: Studies have demonstrated racial and ethnic inequities in medicine, including disparities in the receipt of awards, research funding, and promotions. Yet few studies have examined the link between race and ethnicity and opportunities for medical school students. Our results show that black and Asian medical school students are less likely to be selected for membership in a prestigious medical honor society, Alpha Omega Alpha (AΩA), than white medical school students.

Author Interviews, Education, Gender Differences, JAMA, UCLA / 06.03.2017

MedicalResearch.com Interview with: Julie R. Boiko, MD, MS Resident Physician, PGY1 Department of Pediatrics University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Response: Grand rounds is an over 100-year-old tradition in US medical school clinical departments of recurring, expert-delivered lectures to update physicians and physicians-in-training on recent advances in relevant medicine. We wanted to determine whether gender representation of speakers at grand rounds aligns with the gender distribution of people typically represented in grand rounds audiences -- faculty, residents, and medical students -- by clinical specialty according to national academic medical trainee and workforce statistics. We chose to focus on grand rounds speakers as visible representations of women in academic medicine. This is important because, despite women and men entering medicine at comparable rates, women are much more likely to depart academic medical careers. As current and recent medical students, we considered that consistent exposure to successful female role models in grand rounds speaking venues may positively reinforce women trainees’ desires to continue in academic medical careers. We found that the people at the podiums do not resemble the people in the audience. Only 26% of grand rounds speakers are women. Even accounting that some clinical specialties contain few women faculty and residents, grand rounds speakers in most specialties we studied were statistically less likely to be women as compared to faculty and residents. Across the specialties, grand rounds speakers are 44% less likely than medical students, 39% less likely than residents, and 21% less likely than faculty to be women. (more…)
Aging, Author Interviews, Hearing Loss, JAMA, Johns Hopkins / 06.03.2017

MedicalResearch.com Interview with: Dr. Adele Gorman PhD Johns Hopkins Center on Aging & Health The Johns Hopkins University Baltimore, Maryland MedicalResearch.com: What is the background for this study? Response: Hearing loss affects many people, especially older adults. We have previously estimated how common hearing loss is across different age groups and how many adults have hearing loss today. However, we did not know the number of people that are expected to have hearing loss in the coming decades. This is important to know in order to appropriately plan for future hearing health care needs. Recently the National Academies of Sciences, Engineering and Medicine highlighted the crucial need to address hearing loss and made recommendations to improve hearing health care services. However, these recommendations should be considered by policy makers in the context of the number of adults with hearing loss in the coming years. (more…)
Author Interviews, JAMA, Obstructive Sleep Apnea, Sleep Disorders / 04.03.2017

MedicalResearch.com Interview with: Dr. Simone Baiardi MD Department of Biomedical and Neuromotor Sciences, Alma Mater Studiorum University of Bologna MedicalResearch.com: What is the background for this study? Response: Drug-induced sleep endoscopy (DISE) is an useful tool for studying the upper airway dynamic in patients with obstructive sleep apnea syndrome (OSAS), and it’s crucial for the therapeutic choice (especially for non ventilatory treatment, such as surgery). The main limits of DISE are the lack of standardization of procedure and the low inter-observer reliability among non-experienced ENT surgeons. (more…)

MedicalResearch.com Interview with: Dr. Yashashwi Pokharel MD, MSCR Department of Cardiovascular Research Saint Luke’s Mid-America Heart Institute Kansas City, Missouri and Salim S. Virani, MD PhD, FACC, FAHA Associate Professor, Section of Cardiovascular Research Associate Director for Research, Cardiology Fellowship Training Program Baylor College of Medicine Investigator, Health Policy, Quality and Informatics Program Michael E. DeBakey Veterans Affairs Medical Center HSR&D Center of Innovation Staff Cardiologist, Michael E. DeBakey Veterans Affairs Medical Center Houston, TX MedicalResearch.com: What is the background for this study? What are the main findings? Response: Unlike the previous cholesterol management guideline that recommended use of either statin and non-statin therapy to achieve low density lipoprotein cholesterol (LDL-C) target, the 2013 American College of Cardiology/American Heart Association cholesterol management guideline made a major paradigm shift by recommending statin focused treatment in 4 specific patient groups and replaced LDL-C target with fixed statin intensity treatment (moderate to high intensity statin therapy). With this change, it was speculated that a large number of patients would be eligible for statin treatment (in one study, up to 11.1% additional patients were expected to be eligible for statin therapy). Our study provided the real world trends in the use of statin and non-statin lipid lowering therapy (LLT) from a national sample of cardiology practices in 1.1 million patients 14 months before and 14 months after the release of the 2013 guideline. We found a modest, but significant increasing trend in the use of statin therapy in only 1 of the 4 patient groups eligible for statin therapy (i.e., 4.3% increase in the use of moderate to high intensity statin therapy in patients with established atherosclerotic cardiovascular disease). We did not find any significant change in non-statin LLT use. Importantly, about a third to half of patients in statin eligible groups were not receiving moderate to high intensity statin therapy even after the publication of the 2013 guideline. (more…)
Author Interviews, ENT, JAMA, Obstructive Sleep Apnea, Sleep Disorders, UT Southwestern / 02.03.2017

MedicalResearch.com Interview with: Ron B. Mitchell, MD Professor and Vice Chairman, Department of Otolaryngology, Head and Neck Surgery William Beckner Distinguished Chair in Otolaryngology Chief of Pediatric Otolaryngology UT Southwestern and Children's Medical Center Dallas Dallas, TX 75207 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obstructive Sleep Apnea (OSA) has not been widely studies in adolescents. This is one of a few studies that was targeted at 12-17 year olds who were referred for a sleep study for possible OSA. The study included 224 adolescents (53% male). aged 12 to 17 years. The mean BMI was 33.4 and most were either Hispanic or African American (85.3%). A total of 148 (66.1%) were obese. Most adolescents referred for a sleep study (68%), had  Obstructive Sleep Apnea. Normal-weight adolescents were least likely to have OSA at 48%, while obese children were most likely at 77%. Severe OSA was most likely in obese males with tonsillar hypertrophy. (more…)
Author Interviews, Heart Disease, JAMA / 01.03.2017

MedicalResearch.com Interview with: Thomas Engstrøm  MD, PhD The Heart Center | Rigshospitalet | University of Copenhagen | Denmark Professor in cardiology | University of Lund | Sweden Adjunct professor in cardiology | University of Aalborg | Denmark  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Timely reperfusion by primary angioplasty (primary PCI) in patients with ST-elevation myocardial infarction is mandatory. However reperfusion it self can harm the myocardium - so called reperfusion injury. During a number of years ischemic postconditioning (iPOST) by repetitive interruptions of blood flow after reperfusion has been a promising technique to address reperfusion damage. The trial investigated the effect of iPOST in 1200 patients treated with primary PCI and in addition either iPOST or conventional angioplasty. (more…)
