Alzheimer's - Dementia, Author Interviews, Biomarkers, Neurological Disorders, Neurology, University of Pennsylvania / 08.05.2019

MedicalResearch.com Interview with: Lauren McCollum, MDCognitive and Behavioral Neurology FellowPenn Memory Center / Cognitive Neurology DivisionLauren McCollum, MD Cognitive and Behavioral Neurology Fellow Penn Memory Center / Cognitive Neurology Division MedicalResearch.com: What is the background for this study?   Response: Alzheimer’s Disease (AD) is a heterogenous condition, with considerable variability in cognitive symptoms and progression rates. One major reason for this heterogeneity is “mixed pathology,” – i.e., both AD- and non-AD pathology. Examples of non-AD pathology include cerebrovascular disease (CVD), Lewy Bodies, and TDP-43. Pathologically, Alzheimer’s Disease is defined by characteristic amyloid plaques and neurofibrillary tangles, which can be assessed for in living patients with CSF- or PET-based biomarkers for amyloid and tau, respectively. Classically, amyloid deposition begins years or even decades before pathologic tau accumulation, which is in turn associated with brain atrophy and cognitive decline. The recently developed NIA-AA “ATN” research framework allows for the classification of individuals with regard to 3 binary biomarkers: Amyloid (A), Tau (T), and Neurodegeneration (N). An individual’s ATN biomarker status indicates where along the “Alzheimer’s Disease continuum” they lie. Additionally, some ATN statuses are on the “typical AD” continuum, while others are not. Research has shown that 15-30% of cognitively normal older adults have elevated amyloid. It stands to reason that some portion of cognitively impaired individuals with elevated amyloid and neurodegeneration have something other than AD driving their neuronal injury. Within the context of the ATN research framework, this subset of people is the A+T-N+ group (i.e., people who have elevated amyloid and neurodegeneration, but are tau-negative), as amyloid alone (that is, amyloid without tau) is not thought to cause significant cognitive impairment or brain atrophy. Our hypothesis was that, compared to A+T+N+ (a set of typical-AD biomarkers), A+T-N+ have cognitive and neuroimaging profiles that deviate from a typical Alzheimer’s Disease pattern – i.e., with less memory loss and less atrophy in AD-signature regions – and may have biomarkers suggestive of alternate non-AD pathologies [e.g., white matter hyperintensities (WMHs), a marker of CVD].

Author Interviews, Cancer Research, Environmental Risks, University Texas, Urology / 08.05.2019

MedicalResearch.com Interview with: Stephen B. Williams, MD, FACS Chief, Division of Urology Associate Professor, Urology and Radiology Robert Earl Cone Professorship Director of Urologic Oncology Director of Urologic Research Co-Director Department of Surgery Clinical Outcomes Research Program University of Texas Medical Branch at Galveston MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite prior studies evaluating cancer in those living near and working in oil refineries, there remains a gap in knowledge regarding proximity to oil refineries and risk of bladder cancer. Aromatic amines have been associated with increased risk of various cancers including bladder cancer. Texas is a home to the largest numbers of oil refineries in the US. Our goal was to evaluate if there was a link between bladder cancer and living in close proximity to an oil refinery in Texas. Our data did suggest that living within 10 miles of an oil refinery was associated with a small increase in risk of bladder cancer. These data support further research to validate these findings.

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, Dermatology, Environmental Risks, FDA, JAMA / 06.05.2019

MedicalResearch.com Interview with: David Strauss, MD, PhD Director, Division of Applied Regulatory Science U.S. Food and Drug Administration Center for Drug Evaluation and Research MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is unknown whether most active ingredients in sunscreens are absorbed. FDA has provided guidance that sunscreen active ingredients with systemic absorption greater than 0.5 ng/mL or with safety concerns should undergo nonclinical toxicology assessment including systemic carcinogenicity and additional developmental and reproductive studies. This randomized clinical trial demonstrated systemic exposure of 4 commonly used sunscreen active ingredients on application of sunscreen products under maximal use conditions consistent with current sunscreen labeling. All 4 sunscreen active ingredients tested resulted in exposures exceeding 0.5 ng/mL.  (more…)
Author Interviews, Brigham & Women's - Harvard, Education, JAMA / 06.05.2019

MedicalResearch.com Interview with: Arabella L. Simpkin,  MD, MMSc Associate Director, Center for Educational Innovation and Scholarship, MGH Associate Program Director, Education and Curriculum, Internal Medicine Residency, MGH Instructor in Medicine, Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: The academic health care environment has changed in unprecedented ways over several decades, with mounting evidence that faculty are becoming increasingly more unhappy, dissatisfied, and burnt out in their work. Concern for faculty wellbeing is high, with much speculation about causes of burnout. Comprehending what affects satisfaction at work in academic health care centers is critically important to stem this epidemic of discontent. For physicians, satisfaction has been reported to be associated with quality of care delivered, particularly as measured by patient satisfaction; faculty retention and job satisfaction are intricately linked, with dissatisfied physicians more likely to leave the profession and to discourage others from entering. Other industries that have suffered similar rises in employee discontent have found that demonstration of respect is the most important leadership behavior in improving employees satisfaction. To our knowledge this factor has not been looked at in healthcare professionals. To address this gap, we sought to determine key variables influencing satisfaction at work for faculty in a large academic medical center in the United States. (more…)
Author Interviews, Dermatology, Microbiome, Pediatrics, UCSD / 30.04.2019

MedicalResearch.com Interview with: Dr. Jusleen Ahluwalia MD Second-year Dermatology resident University of California, San Diego MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Preadolescence is an interesting stage during which changes in microbial diversity can coincide with the development of acne. This study is the largest assessment of preadolescent acne microbiome in the literature to date. In this study, we found that early acne in preadolescent females is characterized by an abundance of Streptococcus mitis, while later stages are characterized by a predominance of Cutibacterium acnes (formerly known as Propionibacterium acnes).   (more…)
Alzheimer's - Dementia, Author Interviews, End of Life Care, JAMA, University of Pennsylvania / 30.04.2019

MedicalResearch.com Interview with: Emily Largent, PhD, JD, RN Assistant Professor, Medical Ethics and Health Policy Perelman School of Medicine Leonard Davis Institute of Health Economics University of Pennsylvania  MedicalResearch.com: What is the background for this study? What are the main findings?  Response:  Public support for aid in dying in the United States is rapidly growing.  As a result, we’re now seeing debates about whether to expand access to aid-in-dying to new populations – such as people with Alzheimer’s disease – who wouldn’t be eligible under current laws. With those debates in mind, we asked currently healthy people who recently learned about their risk for developing Alzheimer’s disease dementia (i.e., due to the presence of amyloid, an Alzheimer’s disease biomarker) whether they would be interested in aid-in-dying. Our findings suggest that about 20% of individuals with elevated amyloid may be interested in aid-in-dying if they become cognitively impaired.   (more…)
Author Interviews, Cancer Research, JAMA, MD Anderson, Radiation Therapy / 30.04.2019

MedicalResearch.com Interview with: Quynh-Nhu Nguyen, MD Department of Radiation Oncology The University of Texas MD Anderson Cancer Center Houston MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This is the first non-spine bone metastases trial comparing higher dose single fraction radiotherapy vs multifraction standard fractionated radiotherapy for patients with painful bone metastases. The results of this trial demonstrated more durable pain relief and superior local control for patients treated in the higher dose(12 Gy-16 Gy)  single fraction RT compared to standard 30 Gy/10 fractions multifractionated regimen.  This trial supports the previous multiple randomized trials which recommend single fraction should be standard palliative radiotherapy regimen for bone metastases.  This trial is unique in that it addressed previous criticism that single fraction does not provide durable palliation with lower 8 gy single fraction and result in higher re-irradiation rates.  This trial on the contrary with the utilization of modern radiotherapy techniques, demonstrated we can safely and more effectively deliver a higher single fraction radiotherapy regimen for improvement in the quality of life for patients.  This higher dose should be the new standard single fraction regimen for patients who are functional and have a longer life expectancy.  (more…)
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…)
UCSD / 25.04.2019

MedicalResearch.com Interview with: Amir Zarrinpar, MD, PhD Assistant Professor, Division of Gastroenterology University of California, San Diego  MedicalResearch.com: What is the background for this study? Response: Over the last decade, physicians are beginning to recognize obesity as a disease that requires specific attention; they are more engaged with treating obesity itself rather than its metabolic consequences (such as type 2 diabetes, high blood pressure, cholesterol problems, and/or non-alcoholic fatty liver disease). However, treating obesity is very difficult and many patients don’t succeed in getting the minimum weight loss (approximately 5%) needed to get beneficial health effects. Recent obesity treatment guidelines recommend avoiding placing patients who are obese on obesogenic medication, or medication that have weight gain as a significant side effect. Despite this recommendation, we noticed many patients who seek treatment for obesity in our clinics are on obesogenic medications. We first noticed that about 40% of patients who are undergoing bariatric surgery at UCSD were prescribed an obesogenic medication. These patients had worse weight loss outcomes compared to patients who did not have any obesogenic medications published that study recently in the International Journal of Obesity. We wondered whether these findings were specific to bariatric surgery or if patients who were undergoing behavioral treatment (that is, diet and exercise) also had poor weight loss outcomes if they were on obesogenic medications.  (more…)
Author Interviews, Gender Differences, Johns Hopkins / 23.04.2019

MedicalResearch.com Interview with: Kellan E. Baker, MPH, MA Centennial Scholar PhD Candidate Health Policy Research Scholar Department of Health Policy and Management Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study shows that transgender adults in the U.S. today have significantly worse health-related quality of life than cisgender (non-transgender) adults, as measured by self-reported health status and number of recent days of poor physical or mental health. The study is important because it quantifies the gap in health-related quality of life between transgender and cisgender people, and it relies on a survey that allows us to believe that these findings are likely true not just for the people who answered the survey but for the U.S. as a whole. Health-related quality of life is a very broad term that describes a person’s whole sense of well-being—we might think of it as the answer to the question, “how are you doing these days?” The answer has to do not just with your physical health but also your mental health, your outlook on your life and your community, your feelings of wholeness and happiness. Sources such as the National Academy of Medicine and the U.S. Transgender Survey have documented that transgender people face discrimination in areas of everyday life such as housing, health care, and public spaces. Encounters with discrimination don’t just keep transgender people from getting services they need: they hurt trans people both physically and mentally.  (more…)
Author Interviews, NYU, PTSD, Technology / 22.04.2019

MedicalResearch.com Interview with: Charles R. Marmar, MD The Lucius N. Littauer Professor Chair of the Department of Psychiatry NYU Langone School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Several studies in recent years have attempted to identify biological markers that distinguish individuals with PTSD, with candidate markers including changes in brain cell networks, genetics, neurochemistry, immune functioning, and psychophysiology. Despite such advances, the use of biomarkers for diagnosing PTSD remained elusive going into the current study, and no physical marker was applied in the clinic. Our study is the first to compare speech in an age and gender matched sample of a military population with and without PTSD, in which PTSD was assessed by a clinician, and in which all patients did not have a major depressive disorder. Because measuring voice qualities in non-invasive, inexpensive and might be done over the phone, many labs have sought to design speech-based diagnostic tools  (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, Red Meat / 22.04.2019

MedicalResearch.com Interview with: Marta Guasch-Ferre, PhD Research Scientist, Dept of Nutrition Harvard TH Chan School of Public Health Instructor of Medicine, Channing Division of Network Medicin Harvard Medical School Boston, MA, 02115   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Previous findings from randomized controlled trials evaluating the effects of red meat on cardiovascular disease risk factors have been inconsistent. But our new study, which makes specific comparisons between diets high in red meat versus diets high in other types of foods, shows that substituting red meat with high-quality protein sources lead to more favorable changes in cardiovascular risk factors. That is, to properly understand the health effects of red meat, it’s important to pay attention to the comparison diet. People do not simply eat more or less meat – it will almost always be in substitution with other foods.  (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, JAMA, Radiation Therapy, Technology / 19.04.2019

MedicalResearch.com Interview with: Raymond H Mak, MD Radiation Oncology Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? 
  • Lung cancer remains the most common cancer, and leading cause of cancer mortality, in the world and ~40-50% of lung cancer patients will need radiation therapy as part of their care
  • The accuracy and precision of lung tumor targeting by radiation oncologists can directly impact outcomes, since this key targeting task is critical for successful therapeutic radiation delivery.
  • An incorrectly delineated tumor may lead to inadequate dose at tumor margins during radiation therapy, which in turn decreases the likelihood of tumor control.
  • Multiple studies have shown significant inter-observer variation in tumor target design, even among expert radiation oncologists
  • Expertise in targeting lung tumors for radiation therapy may not be available to under-resourced health care settings
  • Some more information on the problem of lung cancer and the radiation therapy targeting task here:https://www.youtube.com/watch?v=An-YDBjFDV8&feature=youtu.be

Author Interviews, Melanoma, Pediatrics, Race/Ethnic Diversity, Stanford / 18.04.2019

MedicalResearch.com Interview with: Susan M. Swetter, MD Professor of Dermatology Director, Pigmented Lesion & Melanoma Program Physician Leader, Cancer Care Program in Cutaneous Oncology Stanford University Medical Center and Cancer Institute MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The Stanford Pigmented Lesion and Melanoma and Program and Pediatric Dermatology Division participated in the long-term management of children, adolescents and young adults (<25 years of age) with melanoma and atypical melanocytic neoplasms, including atypical Spitz tumors (ASTs) that may be histopathologically challenging to differentiate from true melanoma. Over a 23-year period, we have observed increased racial-ethnic diversity in young patients with these diagnoses, especially in the presentation of young individuals with darker skin phenotypes and more clinically amelanotic (nonpigmented) lesions compared to patients with lighter skin.  (more…)
Author Interviews, Brain Injury, Stem Cells, Surgical Research, University of Pittsburgh / 18.04.2019

MedicalResearch.com Interview with: Dr. David Okonkwo, M.D., Ph.D., Professor of Neurological surgery Director of the Neurotrauma Clinical Trials Center University of Pittsburgh Dr. Okonkwo discusses the results from the STEMTRA Phase 2 trial evaluating the efficacy and safety of SB623 in patients with chronic motor deficit from traumatic brain injury. The results were presented at the American Association of Neurological Surgeons (AANS), April 2019 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Traumatic brain injury (TBI) is a major cause of death and disability in the US and around the globe. The effects of TBI are often long-lasting, with more than one-third of severe TBI patients displaying a neuromotor abnormality on physical examination 2 years following injury and, yet, there are no effective treatments. The public health implications are staggering: there are approximately 1.4 million new cases of TBI in the US annually, resulting in over 50,000 deaths and 80,000 disabilities; over 5 million Americans currently suffer from long-term disability caused by TBI. A successful neuroregenerative or neurorestorative therapy, such as stem cell implantation, would have significant impact. (more…)
Author Interviews, Memory, NIH, Sleep Disorders / 17.04.2019

MedicalResearch.com Interview with: Leonardo G. Cohen, M.D., Ph.D., Senior Investigator Marlene Bönstrup, M.D., Postdoctoral fellow in  Dr. Cohen's lab NIH's National Institute of Neurological Disorders and Stroke MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Learning a new skill is typically divided into online (during practice) and offline (after practice has ended) components. Particularly motor skill learning occurs to a considerable degree offline, meaning that performance further improves even after practice has ended. A single practice session itself however, is typically divided into short (level of seconds) periods of practice and rest. In this study, we set out to investigate the contribution of those short periods of practice and rest to the learning during a practice session (i.e. online learning). We found that during early motor skill learning, when most of the total learning occurs, performance improvements actually precipitate during short periods of rest whereas during practice periods, performance mostly stagnated. We found a signature of neural activity predictive of those performance improvements during rest: The lower the beta rhythmic activity in the parietofrontal regions of the brain during those short periods of rest, the higher were participant’s performance jumps.  (more…)
Author Interviews, Brigham & Women's - Harvard, Lipids, Stroke / 16.04.2019

MedicalResearch.com Interview with: Pamela M. Rist, ScD Assistant Professor of Medicine, Harvard Medical School Brigham and Women's Hospital, Division of Preventive Medicine Boston, MA 02215  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although hypercholesterolemia is a risk factor for ischemic stroke, some prior studies have observed an inverse association between total and low-density lipoprotein (LDL) cholesterol and risk of hemorrhagic stroke.  However, many studies were not able to study this association specifically among women. Our main result was very low levels of low-density lipoprotein (LDL) cholesterol or low levels of triglycerides were associated with an increased risk of hemorrhagic stroke among women. (more…)
Author Interviews, Depression, Mental Health Research, Vanderbilt / 16.04.2019

MedicalResearch.com Interview with: Lauren Gaydosh, PhD Assistant Professor Center for Medicine, Health, and Society Public Policy Studies Vanderbilt University  MedicalResearch.com: What is the background for this study?   Response: Several years ago, life expectancy at birth in the United States declined, and this decline has continued every year since. Part of the cause underlying this decline is that midlife mortality – deaths among those 45-54 – has been rising. This increase in midlife mortality has been attributed by some to the “deaths of despair” – a cluster of causes of death including suicide, drug overdose, and alcohol-related disease - and has been most pronounced among middle-aged white adults with a HS degree or less. In our research, we wanted to better understand the indicators of despair that would be predictive of these causes of death. Things like depression, substance use, and suicidal ideation. And study them in individuals before the period of elevated risk of death – in other words, before they reached middle age. Our goal was to evaluate whether these markers of despair were rising for a younger cohort, and whether this pattern was isolated to white adults with low education. (more…)
Author Interviews, Cognitive Issues, Memory, University Texas / 16.04.2019

MedicalResearch.com Interview with: Dr. Sandra Bond Chapman PhD Founder and Chief Director, Center for BrainHealth, Co-Leader, The BrainHealth Project University of Texas, Dallas MedicalResearch.com: What is the background for this study? Response: Finding effective treatments to reverse or slow rates of cognitive decline for those at risk for developing dementia is one of the most important and urgent challenges of the 21st century. Brain stimulation is gaining attention as a viable intervention to increase neuroplasticity when used in isolation or when combined with cognitive training regimens. Given the growing evidence that certain cognitive training protocols, such as SMART, benefit people with Mild Cognitive Impairment (MCI), a population that is vulnerable to Alzheimer’s disease, we were interested in exploring whether we could further increase the gains from cognitive training (i.e., SMART) when the training was preceded by brain stimulation using tDCS.  (more…)
Author Interviews, Education, JAMA, University of Pennsylvania / 16.04.2019

MedicalResearch.com Interview with: Krisda Chaiyachati, MD, MPH, MSHP Assistant Professor Medicine, Perelman School of Medicine Clinical Innovation Manager Penn's Center for Health Care Innovation Perelman School of Medicine Medical Director, Penn Medicine's FirstCall Virtual Care   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The United States spends more than $12 billion annually on training young doctors who have rates of burnout and depression at an alarmingly high rate. Yet, we have limited evidence as to what they are doing while training in the hospital. We sought to glimpse into how their day is spent. In the largest study to date, we observed 80 first-year internal medicine physicians (“interns”) for nearly 2200 hours across 194 work shifts at 6 different sites. Our research sought to understand what medical residents did by categorizing training activities into themes such as time spent in education or patient care.  (more…)
Author Interviews, Brigham & Women's - Harvard, Gender Differences, JAMA, Surgical Research / 16.04.2019

MedicalResearch.com Interview with: Nelya Melnitchouk, MD,MSc Director, Program in Peritoneal Surface Malignancy, HIPEC Dr. Melnitchouk is an associate surgeon at Brigham and Women’s Hospital (BWH) and Brigham and Women’s Faulkner Hospital (BWFH) and instructor of surgery at Harvard Medical School. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current literature on women in surgery show that female physicians, particularly those in procedural specialties, face many challenges in balancing responsibilities between work and home. We hypothesized that these challenges may affect career satisfaction more negatively for physician mothers in procedural specialties than those in nonprocedural specialties. In our study, we found that physician mothers in procedural specialties who had more domestic responsibilities were more likely to report a desire to change careers than those in nonprocedural specialties.  (more…)
Author Interviews, JAMA, University of Pennsylvania / 14.04.2019

MedicalResearch.com Interview with: Genevieve P. Kanter, PhD Assistant Professor (Research) of Medicine Medical Ethics and Health Policy University of Pennsylvania Perelman School of Medicine Philadelphia, PA  19104-6021 MedicalResearch.com: What is the background for this study?   Response: Physicians frequently have financial relationships with pharmaceutical and medical device firms, but only recently has information on these financial ties been made available to the public. The Open Payments program, created by the Physician Payment Sunshine Act, has made this industry payments information available through a public website since 2014. Because transparent institutions are believed to engender greater public trust, public disclosure of industry payments could increase public trust in the medical profession, which may have been weakened by physicians' relationships with industry. On the other hand, Open Payments may have decreased public trust because of the focus of media reporting on physicians receiving the largest sums of money. We sought to investigate how Open Payments and the public disclosure of industry payments affected public trust in physicians and in the medical profession. We compared changes in trust among patients who lived in states where payments information had, by state statute, previously been made available, to changes in trust among patients who lived in states where this information became newly available through Open Payments.

Author Interviews, Exercise - Fitness, Gender Differences, Heart Disease, JAMA, Johns Hopkins, Women's Heart Health / 14.04.2019

MedicalResearch.com Interview with: Erin D. Michos, MD, MHS, FACC, FAHA, FASE Associate Professor of Medicine and Epidemiology Associate Director of Preventive Cardiology Ciccarone Center for the Prevention of Heart Disease Johns Hopkins School of Medicine Victor Okunrintemi, MD, MPH Department of Internal Medicine East Carolina University Greenville, North Carolina  MedicalResearch.com: What is the background for this study?   Response: Women are less physically active than men on average, and the lack of regular physical activity has been associated with increased risk of cardiovascular disease and poorer health outcomes. Although recommendations encouraging regular physical activity has been in place for decades, we do not know how much of these recommendations are met, particularly among high risk women with established cardiovascular disease for secondary prevention. This study was therefore designed with the aim of describing the 10-year trends for the proportion of women with cardiovascular disease who do not meet these recommend physical activity levels, overall and by key sociodemographic groups, and the associated cost implications.

Author Interviews, Cancer Research, Health Care Systems, JAMA, Outcomes & Safety, Surgical Research, Yale / 12.04.2019

MedicalResearch.com Interview with: Daniel J. Boffa, MD Associate Professor of Thoracic Surgery Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prominent cancer hospitals have been sharing their brands with smaller hospitals in the community.  We conducted a series of nationally representative surveys and found that a significant proportion of the U.S. public assumes that the safety of care is the same at all hospitals that share the same respected brand.  In an effort to determine if safety was in fact the same, we examined complex surgical procedures in the Medicare database. We compared the chance of dying within 90 days of surgery between top-ranked hospitals, and the affiliate hospitals that share their brands.  When taking into account differences in patient age, health, and type of procedure, Medicare patients were 1.4 times more likely to die after surgery at the affiliate hospitals, compared to those having surgery at the top-ranked cancer hospitals.

Author Interviews, Cancer Research, JAMA, UT Southwestern / 11.04.2019

MedicalResearch.com Interview with: Nina Niu Sanford, M.D. Assistant Professor UT Southwestern Department of Radiation Oncology Dallas TX 75390 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: There has been increasing interest in use of complementary and alternative medicine in the oncology population – both in terms of its potential efficacy and harms. The main finding of this study is that approximately 1/3 of cancer patients and survivors self-reported using complementary or alternative medicine over the past year, the most common being herbal supplements. Of these patients, approximately 1/3 did not disclose to their physicians that they were doing so. (more…)
Author Interviews, BMJ, Heart Disease, Karolinski Institute / 11.04.2019

MedicalResearch.com Interview with: Huan Song, PhD Center of Public Health Sciences, Faculty of Medicine, University of Iceland, Reykjavík, Iceland Department of Medical Epidemiology and Biostatistics Karolinska Institutet, Stockholm, Sweden MedicalResearch.com: What is the background for this study?   Response: Cardiovascular disease (CVD) presents a group of diseases that are common and sometimes fatal in general population. The possible role of stress-related disorders in the development of CVD has been reported. However, the main body of the preceding evidence was derived from male samples (veterans or active-duty military personnel) focusing mainly on posttraumatic stress disorder (PTSD) or self-reported PTSD symptoms. Data on the role of stress-related disorders in CVD in women were, until now, limited. Although incomplete control for familial factors and co-occurring psychiatric disorder, as well as the sample size restriction, limit the solid inference on this association, especially for subtypes of CVD.

Author Interviews, BMJ, Health Care Systems, University of Pennsylvania / 11.04.2019

MedicalResearch.com Interview with: Genevieve P. Kanter, PhD Assistant Professor (Research) of Medicine Medical Ethics and Health Policy University of Pennsylvania Perelman School of Medicine Philadelphia, PA  MedicalResearch.com: What is the background for this study?   Response: In 2010, the US Congress—concerned about the adverse influence of financial relationships between physicians and drug and device firms, and the lack of transparency surrounding these relationships—enacted the Physician Payments Sunshine Act. This legislation required pharmaceutical and medical device firms to report, for public reporting through the Open Payments program, the payments that these firms make to physicians. We sought to evaluate the effect of Open Payments' public disclosure of industry payments information on US adults' awareness of the issue of industry payments and knowledge of whether their physicians' had received industry payments.  (more…)

The aim of the new system was to increase transplant in patients who were highly sensitized (difficult matches based on reactive antibodies) and to improve access to underserved populations. (more…)
AACR, Author Interviews, Cancer Research, HPV, University of Michigan, Vaccine Studies / 05.04.2019

MedicalResearch.com Interview with: Diane Harper, M.D., M.P.H., M.S. Professor of Family Medicine and Obstetrics and Gynecology Senior Associate Director, Michigan Institute for Clinical and Health Research Physician Director for Community Outreach, Engagement and Health Disparities, Rogel Cancer Center Michigan Medicine  MedicalResearch.com: What is the background for this study? Response: There is no current cure for women with HPV infection that has progressed to CIN 2/3 disease. The only treatment is for the diseased cervix, and does not eliminate the risk of another CIN 2/3 from the HPV infection 15-20 years later. This vaccine is made from a live virus that has 3 genes inserted:  human cytokine IL-2, and modified forms of HPV 16 E6 and E7 proteins. When the vaccine is injected subcutaneously, the proteins for HPV 16/E6 and E7 and the cytokine LI-2 proteins are made. These proteins trigger the immune response.  This is very different form imiquimod which is topical and not specific for HPV. (more…)
