Author Interviews, Immunotherapy, JAMA, Melanoma / 10.05.2017

MedicalResearch.com Interview with: Yasuhiro Nakamura, M.D., Ph.D. Associate Professor Department of Skin Oncology/Dermatology Comprehensive Cancer Center Saitama Medical University International Medical Center Hidaka, Saitama MedicalResearch.com: What is the background for this study? What are the main findings? Response: Regressing nevi, which are frequently associated with halo phenomenon, occur in approximately 1% of the general population. In patients with melanoma, spontaneous or treatment-related depigmentation of the skin (vitiligo) is sometimes observed. Although humoral and cellular immune responses may play a crucial role in their development, immune reactions to benign melanocytic nevi (BMN) without a halo are extremely rare in both the general population and in patients with melanoma. This publication reports a rare case with multiple metastatic melanomas who showed a remarkable clinical response to nivolumab with a simultaneous prominent immune reaction to multiple BMN without halo phenomenon. This rare phenomenon may be associated with dramatic efficacy of nivolumab in melanoma patients. (more…)

MedicalResearch.com Interview with: John H Kempen, MD, PhD Protocol Chair, MUST Trial Follow-up Study; Vice Chair, MUST Research Group Director of Epidemiology for Ophthalmology, Massachusetts Eye and Ear Harvard Medical School Editor-in-Chief, Ophthalmic Epidemiology President, Sight for Souls MedicalResearch.com: What is the background for this study? Response: Uveitis is about the fifth leading cause of blindness in the united states.  Among types of uveitis, intermediate, posterior and panuveitis are the leading causes of blindness.  Before 2005, systemic therapy with corticosteroids—supplemented when indicated with immunosuppressive drugs (most of the time)—was the primary treatment recommended for these conditions.  With approval of the fluocinolone acetonide implant in 2005 for intermediate, posterior and panuveitis, it became unclear which of the alternative treatment approaches should be the treatment of choice. The multicenter uveitis steroid treatment (must) trial was initiated in 2005 to directly compare the alternative treatments.  Systemic therapy was administered using high dose prednisone followed by tapering of corticosteroids to maintenance doses of 10 mg/day or less (generally 7.5 mg/day or less) or to zero; this was supplemented by immunosuppressive corticosteroid-sparing drugs in 88% of participants.  Implant therapy was done by initial quieting of the anterior chamber of the eye with topical, injected or systemic corticosteroids followed by surgical implant placement within 28 days (first eye) and 56 days (second eye if it was indicated).  After this, systemic corticosteroids and immunosuppressive drugs were tapered off.

MedicalResearch.com Interview with: Rohit Varma, MD, MPH Executive Director - USC Roski Eye Institute and Dean of the Keck School of Medicine of USC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Visual impairment in early childhood has profound impact on a child’s development. It can significantly impair development of visual, motor, and cognitive function1-3 and lead to adverse psychosocial consequences. There has been a lack of accurate data characterizing the current and expected numbers of visual impairment cases among preschool children in the United States from 2015 to 2060. The number of preschool children with visual impairment is projected to increase by 26% in 2060. And 69% of these visual impairment will result from simple uncorrected refractive error such hyperopia and myopia, which can be prevented or treated by low-cost refractive correction. (more…)

Response: Nirat Beohar MD, Director of the Cardiovascular Catheterization Laboratory and Vice-Chief of Cardiology at the Columbia University Division of Cardiology at the Mount Sinai Medical Center and co-authors report the effect of trans-catheter aortic valve replacement (TAVR) on subsequent renal function and outcomes in high-risk and inoperable patients presenting with baseline renal dysfunction (eGFR < 60 ml/min/1.73 m2). This was a sub-study of patients undergoing TAVR in the PARTNER 1 trial and continued access registry that was conducted in 25 centers in the United States and Canada. (more…)
Author Interviews, JAMA, Pharmacology, UCLA / 03.05.2017

MedicalResearch.com Interview with: Ian Larkin, PhD Assistant Professor of Strategy UCLA Anderson School of Management MedicalResearch.com: What is the background for this study? Response: The study examined whether restrictions put in by medical centers on salesperson visits to physicians, known as “detailing,” affected subsequent physician prescribing behavior. Detailing represents the most prominent form of pharmaceutical marketing. Detailing visits allow the sharing of scientific information, but they also often involve small gifts for physicians and their staff, such as meals. Pharmaceutical companies incur far greater expenditures on detailing visits than they do on direct-to-consumer marketing, or even on research and development of new drugs. Specifically, the study examined detailing restrictions put into place by 19 academic medical centers (AMCs) in five states in the U.S. It compared changes in prescribing by thousands of AMC physicians whose practices limited typical elements of detailing visits, such as provisions of meals and educational gifts, to a carefully matched control group of similar physicians practicing in the same geographic regions but not subject to such detailing restrictions. The study, which included more than 25,000 physicians and all 262 drugs in eight major drug classes — from statins to sleep aids to antidepressants, representing more than $60 billion in aggregate sales in the United States — was, to date, by far the most comprehensive to examine the impact of detailing restrictions. The comprehensive and quasi-experimental methodology, which compared prescribing behavior before and after implementation of policies, and which included a large matched control group of physicians not subject to policy changes, was an important innovation relative to prior research. The study used prescription data from CVS Caremark, one of the largest pharmacy benefit managers in the United States. (more…)
Author Interviews, JAMA, Opiods, Pain Research, Surgical Research / 03.05.2017

MedicalResearch.com Interview with: Chad M. Brummett, M.D. Associate Professor Director, Clinical Anesthesia Research Director, Pain Research Department of Anesthesiology Division of Pain Medicine 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 tremendous attention in recent years, but most of the focus has been on chronic pain, opioid abuse and overdose. Far less attention has been paid to the importance of acute care prescribing (e.g. surgical pain) in patients that are not chronic opioid users. We found that 5-6% of patients not using opioids prior to surgery continued to fill prescriptions for opioids long after what would be considered normal surgical recovery. Moreover, the rates of new chronic use did not differ between patients having major and minor surgeries, suggesting that patients continue to use these pain medications for something other than simply pain from surgery. Building on other work by our group, and the few additional studies done on the topic to date, these data suggest that pain medications written for surgery are a major cause of new chronic opioid use for millions of Americans each year.

Author Interviews, Heart Disease, JAMA, Surgical Research / 02.05.2017

MedicalResearch.com Interview with: Dr. PJ Devereaux MD, PhD, FRCP(C) Director of the Division of Cardiolog Scientific Leader of the Anesthesiology, Perioperative Medicine and Surgical Research Group at the Population Health Research Institute Professor and University Scholar in the Departments of Health Research Methods, Evidence, and Impact and Medicine McMaster University MedicalResearch.com: What is the background for this study? Response: Although the majority of patients undergoing noncardiac surgery benefit from surgery and do well, even when a small proportion of these patients have a serious complication it represents a major population issue. A recent publication in JAMA Cardiology established that >5 million Americans age ≥45 years undergo major in-patient noncardiac surgery annually, and 1.3% of these patients die in the hospital. This means 65,000 of these patients die, and cardiovascular causes are a dominant cause. (more…)
Author Interviews, JAMA, Pain Research, Pharmacology, UT Southwestern / 01.05.2017

MedicalResearch.com Interview with: Una Makris MD, MSc Clinical Investigator at the VA North Texas Health System VA North Texas Health Care System Assistant Professor at UT Southwestern Medical Center Departments on Internal Medicine and Clinical Sciences Dr. Makris is a Rheumatologist, clinically, and spends the majority of time focused on clinical research investigating how to improve outcomes for adults with back pain. MedicalResearch.com: What is the background for this study? Response: Back pain is the most common type of musculoskeletal (MSK) pain. We know that expenditures for back pain exceed $100 billion each year (and this was in 2005). Back pain results in tremendous disability (including reduced mobility) and impaired quality of life (not exclusive to physical consequences, but also including important psychosocial repercussions). We also know that statins are prescribed very often, and frequently in younger populations who are active. Some reports suggest that statins may have a protective effect on  musculoskeletal conditions such as back pain. (more…)
Author Interviews, Blood Pressure - Hypertension, JAMA, OBGYNE / 01.05.2017

MedicalResearch.com Interview with: Dr. Maureen Phipps, USPTS Task Force member Department chair and Chace-Joukowsky professor of obstetrics and gynecology Assistant dean for teaching and research on women's health Warren Alpert Medical School of Brown University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Preeclampsia, which includes high blood pressure after 20 weeks of pregnancy, is one of the most serious health problems affecting pregnant women. After reviewing the evidence, the Task Force found the benefits of screening for preeclampsia outweighed the harms and recommended screening pregnant women for preeclampsia with blood pressure measurements throughout pregnancy. The evidence showed mothers and their babies are likely to benefit from screening, as screening leads to treatment that reduces their risk of severe complications, including death. (more…)
ADHD, Author Interviews, Education, Gender Differences, JAMA, Pediatrics / 01.05.2017

MedicalResearch.com Interview with: Professor Jill Pell MD Director of Institute (Institute of Health and Wellbeing) Associate (School of Medicine, Dentistry and Nursing) University of Glasgow MedicalResearch.com: What is the background for this study? Response: The novelty of our study lies in its scale and scope. In terms of scope, it reported on six educational outcomes and three health outcomes in the same group of children. In terms of scale, it is the first study of a whole country to compare educational outcomes of children with treated ADHD with their unaffected peers and is more than 20 times larger than previous studies on similar educational outcomes. The only previous countrywide study on health outcomes, included only children with very severe ADHD who were in psychiatric hospitals. (more…)

MedicalResearch.com Interview with: David C Neely, MD The University of Alabama at Birmingham MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study examined the prevalence of eyes with age-related macular degeneration (AMD) in patients seen in primary eye care clinics who purportedly have normal macular health. Approximately 25.0% of eyes deemed to be normal based on dilated eye examination by primary eye care providers had macular characteristics that indicated age-related macular degeneration. (more…)

MedicalResearch.com Interview with: Elinore J. Kaufman, MD, MSHP Department of Surgery, New York Presbyterian Hospital Weill Cornell Medicine New York, New York MedicalResearch.com: What is the background for this study? What are the main findings? Response: Deaths of civilians in contact with police have recently gained national public and policy attention. However, we know very little about nonfatal injuries, which far outnumber deaths. MedicalResearch.com: What should readers take away from your report? Response: Nonfatal injuries are much more pervasive than law enforcement-associated deaths, and rates have remained stable over several years, at approximately 51,000 emergency department visits and hospitalizations each year. These injuries primarily affect young men, and mental illness is a common theme. As a physician, my goal is always to get to zero preventable injuries. (more…)
Author Interviews, Dermatology, JAMA, Melanoma, Technology / 27.04.2017

MedicalResearch.com Interview with: Laura Korb Ferris, MD, PhD Associate Professor, University of Pittsburgh Clinical and Translational Science Institute Director of Clinical Trials Department of Dermatology University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: We found that a non-invasive adhesive patch applied to the skin over a pigmented skin lesion allowed us to capture enough genetic material from the lesion to analyze and predict if that lesion is likely to be melanoma, meaning a biopsy is warranted, or if it is likely benign, meaning the patient would not need a skin biopsy. In this study, we asked dermatologists to use their clinical judgement to decide if they would recommend biopsying a skin lesion based on photos and information about the lesion and the patients, such as the patient's age, personal and family history of skin cancer, and if the lesion was new or changing. We then provided them the read out of the gene test and asked them how this influence their decision. We found that with this test result, dermatologists were more accurate in their decision making, meaning they were more likely to recommend biopsy of melanomas and less likely to biopsy harmless moles than they were without the test. This is important as it means this test has the potential to reduce the number of unnecessary skin biopsies performed, saving patients from undergoing a procedure and having a scar as a result, without increasing the risk of missing a melanoma.

Addiction, Author Interviews, Cannabis, JAMA / 27.04.2017

MedicalResearch.com Interview with: Deborah S. Hasin, Ph.D. Professor of Epidemiology Columbia University New York, New York 10032 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Among adults, the prevalence of cannabis use and cannabis use disorders has increased in recent years. Concerns have been raised that for various reasons, medical marijuana laws would promote use of cannabis and consequently, cannabis-related consequences. Many studies show that this didn't happen among adolescents, but very little was known about the relationship between medical marijuana laws and adults. Using data from three surveys spanning the years 1991-2013, the study findings suggested that medical marijuana laws did play a role in increasing rates of cannabis use and cannabis use disorders.

Author Interviews, HIV, JAMA, Pediatrics, Sexual Health / 25.04.2017

MedicalResearch.com Interview with: Robin Lin Miller, Ph.D. Professor, Ecological-Community Psychology Co-Director, MA in Program Evaluation Chair, Graduate Program in Ecological-Community Psychology Michigan State University East Lansing, MI 48824 MedicalResearch.com: What is the background for this study? Response: We wanted to identify promising strategies for providing access to HIV-testing for gay and bisexual male youth. We were especially interested in testing strategies to reach gay and bisexual male youth of color, as they bear a disproportionate burden of the HIV epidemic and are the least likely to be aware of their HIV status. We also wanted to explore approaches to successfully link these youth with HIV-negative test results to diverse HIV prevention services, including pre-exposure prophylaxis, when warranted. Although some argue that the ideal place to test adolescents and young adults is via emergency rooms and in routine medical care visits, we found that we were able test many more youth with previously undiagnosed HIV-infection through intensive, targeted community outreach efforts. We also tested a much higher proportion of young men of color through targeted outreach. (more…)
Author Interviews, JAMA, Mental Health Research, Pediatrics / 25.04.2017

MedicalResearch.com Interview with: Dr. Yongfu Yu, PhD Department of Clinical Epidemiology Aarhus University Hospital Aarhus, Denmark MedicalResearch.com: What is the background for this study? Response: Bereavement by the death of a close relative is ranked as one of the most severe life events and it is likely to cause psychological stress regardless of coping mechanisms. An increased risk of mortality and adverse health outcomes has been observed among the bereaved spouses, parents, and children. It is estimated that nearly 8% of individuals in the US experienced a sibling death in childhood but much less is known about its health consequences. Sibling relationship tends to be the longest and the most intimate in family thus the death of a sibling can be a devastating life event, especially when this event happens at early ages. However, to our knowledge, no study has investigated the effects of sibling death in childhood on subsequent mortality in bereaved siblings with a long follow-up time. (more…)
Author Interviews, JAMA, Prostate Cancer, UCSF / 24.04.2017

MedicalResearch.com Interview with: Kirsten Bibbins-Domingo, Ph.D., M.D., M.A.S. Lee Goldman, MD, endowed chair in medicine and professor of medicine and of epidemiology and biostatistics University of California, San Francisco Chair of the U.S. Preventive Services Task Force MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prostate cancer is one of the most common cancers to affect men, and the Task Force believes all men should be aware of the benefits and harms of screening for prostate cancer. Prostate cancer screening with PSA testing can help men reduce their chance of dying of prostate cancer or of having metastatic cancer. These are important benefits but occur in a small number of men. There are risks associated with screening, specifically overdiagnosis and overtreatment with surgery and radiation that can have important side effects like impotence and incontinence. Since the release of our 2012 recommendation, new evidence has emerged that increased the Task Force’s confidence in the benefits of screening, which include reducing the risk of metastatic cancer (a cancer that spreads) and reducing the chance of dying from prostate cancer. This draft recommendation also reflects new evidence on the use of active surveillance in men with low-risk prostate cancers that may help mitigate some of the harms in these men by allowing some men with low risk cancer to delay or avoid surgery or radiation. Therefore, in our new 2017 draft recommendation, the Task Force encourages men ages 55 to 69 to make an individual decision about whether to be screened after a conversation with their clinician about the potential benefits and harms. For men age 70 years and older, the potential benefits do not outweigh the harms, and these men should not be screened for prostate cancer. (more…)
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. (more…)
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…)
