Author Interviews, Cognitive Issues, JAMA, Social Issues / 18.05.2018

MedicalResearch.com Interview with: Dr Dorina Cadar Research Associate in Dementia Psychobiology Group Department of Behavioural Science and Health University College London London MedicalResearch.com: What is the background for this study? Response: Dementia is one of the most feared medical conditions, which represents a significant global challenge to health and social care. Education may serve different roles in the development of dementia: it is a proxy for early life experiences and (parental) socioeconomic status, it is related to future employment prospects, income and wealth, determines occupational exposures and characteristics of adult life (e.g., job complexity, work stress, environmental exposures) and it provides lifelong skills for optimal mental abilities and mastery. However, given that education is typically completed many decades before dementia onset, other individual and area-based components of socioeconomic status, such as wealth, income and area deprivation may provide a more accurate indication of current socioeconomic resources.  Also, at older ages, accumulated wealth represents a more robust measure of socioeconomic resources than income or occupation alone.

Author Interviews, JAMA, Medical Imaging, Prostate Cancer, Technology / 17.05.2018

MedicalResearch.com Interview with: Andrew J. Armstrong, MD ScM FACP Associate Professor of Medicine, Surgery, Pharmacology and Cancer Biology Associate Director for Clinical Research in Genitourinary Oncology Duke Cancer Institute Divisions of Medical Oncology and Urology Duke University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Men with prostate cancer commonly develop bone metastases and undergo nuclear medicine bone scans. However, these scans are non-quantitative, and disease burden has been challenging to assess over time and to relate to clinical outcomes. We developed a software program and measurement called the automated bone scan index that essentially reads a standard of care nuclear bone scan, provides a quantitative metric, and demonstrate in a phase 3 trial that this aBSI is highly associated with clinical outcomes including survival, time to symptomatic progression, and prostate cancer specific survival. We accomplished this within a prospective phase 3 international trial of men with metastatic hormone resistant prostate cancer who were followed over a long period of time.  All bone scans were read and measured using the aBSI at baseline, and we found that the aBSI was highly prognostic.  This work validates prior smaller phase 2 BSI studies, and demonstrates both the feasibility and clinical utility for incorporating the aBSI into clinical practice to provide this important prognostic information to patients and providers.

Author Interviews, Cancer Research, J&J-Janssen, Leukemia / 17.05.2018

MedicalResearch.com Interview with: Andrzej Jakubowiak, MD, PhD Professor of Medicine Director, Myeloma Program University of Chicago MedicalResearch.com: What is the background for this announcement? Would you briefly explain what is meant by multiple myeloma?   Response: DARZALEX (daratumumab) in combination with VELCADE (bortezomib), melphalan and prednisone - VMP - received U.S. FDA approval for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant (ASCT). With this most recent approval, DARZALEX is now the first monoclonal antibody approved for newly diagnosed patients with this disease. Multiple myeloma is an incurable blood cancer that occurs when malignant plasma cells grow uncontrollably in the bone marrow. Despite the introduction of new medicines over the last decade, which has led to significant improvements in outcomes for patients with multiple myeloma, multiple myeloma remains an incurable disease. In 2018, it is estimated that 30,700 people will be diagnosed and 12,770 will die from the disease in the United States. (more…)
Author Interviews, Dermatology, Education, JAMA, Melanoma / 17.05.2018

MedicalResearch.com Interview with: Michael S. Kolodney, MD, PhD Section of Dermatology, Department of Medicine West Virginia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Melanoma is easily curable if recognized early.   Dermatologists are good at spotting melanomas because they develop an innate sense of how melanomas appear after examining thousands of malignant and benign lesions.  In contrast, most medical students are relatively disadvantaged by their limited dermatology exposure. We felt that too little experience, rather than lack of knowledge of the rules, is the primary barrier to development of pattern-recognition and intuition as a reliable tool for melanoma diagnosis in non-experts.  To remedy this problem, we developed a novel web-based application to mimic the training of a dermatologist by teaching medical students intuitive melanoma diagnosis in a highly condensed period of time. Our application, which we call Skinder, teaches intuitive visual diagnosis of melanoma by quickly presenting the learner with thousands of benign and malignant skin lesions.  The user makes rapid binary decisions, by swiping right for benign or left for malignant, and receives instant feedback on accuracy. With this application, the learner can amass a mental repository of diagnostic experience in a short amount of time. To determine if intuitive visual diagnosis training is superior to a traditional rule-based approach, we compared our web-based application to a rules based approach, the publicly available INFORMED Skin Education Series. Medical students were tested on the ability top differentiate melanomas from benign pigmented lesions before and after training with either Skinder of the Informed Skin Education Series. The pre-test mean for the Skinder group was 75% correct, compared to 74.7% correct for the INFORMED group. The post-test mean for the skinder application group was 86.3% correct, compared to 77.5% correct for the INFORMED group which was highly signifcant. (more…)
Author Interviews, Infections, Pain Research, PLoS, Urinary Tract Infections / 17.05.2018

MedicalResearch.com Interview with: Ingvild Vik MD Doctoral Research Fellow Department of General Practice Institute of Health and Society - UiO University of Oslo, Norway MedicalResearch.com: What is the background for this study? Response: Uncomplicated urinary tract infection (UTI) is the most common bacterial infection in women. It is painful and troublesome, and even though it is often self-limiting most women who see a doctor will be prescribed an antibiotic, as antibiotics provide quick symptom relief.  Antibiotic resistance is a growing, serious public health problem. Antibiotic use is the main contributor to antibiotic resistance, and to stop the rapid development it is crucial that we reduce unnecessary use of antibiotics. Antibiotics can cause unpleasant and potentially severe side effects, so avoiding unnecessary use is also beneficial for the individual patient. A small German trial published in 2010 by Bleidorn et al. suggested that ibuprofen was non-inferior to the antibiotic ciprofloxacin in achieving symptomatic cure in uncomplicated UTI. This inspired us to conduct a larger trial to compare the anti-inflammatory drug ibuprofen to antibiotics in the treatment of uncomplicated UTI.  (more…)
Author Interviews, Education, Exercise - Fitness, Pediatrics, Social Issues / 17.05.2018

MedicalResearch.com Interview with: Dr Sharon Wheeler PhD Lecturer in Sport, Physical Activity and Health Department of Sport and Physical Activity Faculty of Arts and Sciences Edge Hill University Lancashire MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well-known that family background and parents’ investment in their children has a big impact on a number of outcomes, including how well people do at school, the jobs they get, and how they spend their leisure time. It is also known that it is middle-class parents who tend to work particularly hard to make sure their children get on in life. This research starts to question whether parents’ investment in their children’s organised activities is having the desired impact. Parents initiate and facilitate their children’s participation in organised activities as it shows that they are a ‘good’ parent and they hope such activities will benefit their children in both short-term (keeping fit and healthy, developing friendship groups) and long-term ways (getting jobs, having lots of opportunities in the future). The reality, which has been highlighted in this research, is that while children might experience some of these benefits, a busy organised activity schedule can put considerable strain on parents’ resources and families’ relationships, as well as potentially harm children’s development and well-being.

Author Interviews, Genetic Research, JAMA, Schizophrenia / 17.05.2018

MedicalResearch.com Interview with: Tobias Kaufmann PhD Norwegian Centre for Mental Disorders Research (NORMENT), KG Jebsen Centre for Psychosis Research, Division of Mental Health and Addiction, Oslo University Hospital & Institute of Clinical Medicine University of Oslo, Oslo, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past years, a lot of work has pointed toward impaired brain networks in schizophrenia. With this work we assessed brain network stability across different loads of a cognitive task using functional magnetic resonance imaging of the brain. Based on our earlier work on adolescents with pre-clinical signs of mental illness who showed decreased stability of networks across different tasks and conditions, we hypothesized that brain networks in adults with schizophrenia show similar properties of decreased stability. Our results confirmed this hypothesis. Stability was reduced in several large-scale brain networks across the sampled age range from early adulthood to the sixties. Further, network stability was associated with polygenic risk for schizophrenia as well as cognitive task performance. (more…)
Author Interviews, BMJ, Depression, Exercise - Fitness / 17.05.2018

MedicalResearch.com Interview with: Prof. Sarah E Lamb,  MSc, MA, MCSP, Grad Dip Statistics, DPhil Centre for Rehabilitation Research and Centre for Statistics in Medicine Nuffield Department of Orthopaedics Rheumatology & Musculoskeletal Sciences Botnar Research Centre, University of Oxford, Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: Scientists and clinicians have considered the possibility that higher intensity aerobic and muscle strength training might have a beneficial effect in preventing dementia or slowing the progression of cognitive impairment in those who have dementia. The hypothesis has come mostly from animal research. The main findings of our research which used a large sample and high quality methods was that higher intensity exercise, whilst possible, did not slow cognitive impairment. Neither did it have an impact on the functional and behavioural outcomes for people with dementia. It was a substantial commitment for people to participate in the programmes, although many enjoyed the experience and their physical fitness improved. (more…)
Artificial Sweeteners, Author Interviews, Nutrition, Sugar, Weight Research / 17.05.2018

MedicalResearch.com Interview with: “Soda” by Jannes Pockele is licensed under CC BY 2.0Kimber L. Stanhope, Ph.D., M.S., R.D. Research Nutritional Biologist Department of Molecular Biosciences: SVM University of California, Davis  MedicalResearch.com:? What are the main findings of this study? Response: Sugar-sweetened beverages increase risk factors for cardiometabolic disease compared with calorically-equal amounts of starch. We are not the first group of experts to reach this conclusion. The Nutrition and Chronic Diseases Expert Group reached a similar conclusion last year (Micha, 2017). Yet very different conclusions/opinions are being still being published by other researchers. (Latest example: Archer E., In Defense of Sugar: A Critique of Diet-Centrism. Progress in Cardiovascular Disease, May 1, 2018). These conflicting conclusions confuse the public and undermine the implementation of public health policies, such as soda taxes and warning labels, that could help to slow the epidemics of obesity and cardiometabolic disease. We hope that the careful review of the evidence and the discussion of issues that can lead to conflicting opinions in nutrition research in this paper will help to clarify this issue. Consumption of polyunsaturated (n-6) fats, such as those found in some vegetable oils, seeds, and nuts, lowers disease risk when compared with equal amounts of saturated fats. It is important to note however, that the effects of saturated fat can vary depending on the type of food. Dairy foods such as cheese and yogurts, which can be high in saturated fats, have been associated with reduced cardiometabolic risk. The non-caloric sweetener aspartame does not promote weight gain in adults. Aspartame is the most extensively studied of the non-caloric sweeteners. None of the dietary intervention studies that have investigated the effects of aspartame consumption have shown it promotes body weight gain. This includes studies in which the adult research participants consumed aspartame for 6 months, 1 year or 3 years. (more…)

MedicalResearch.com Interview with: https://www.gwpharm.com/epilepsy-patients-caregivers/patientsAnup Patel, M.D. Section Chief of Neurology Interim Division Chief of Neurology Nationwide Children’s Hospital MedicalResearch.com: What is the background for this study? Response: The study evaluated kids and adults with an epilepsy syndrome (Lennox Gastaut Syndrome – LGS) that is often difficult to treat and does not respond well to current medical treatment.  The study was a double blind randomized control trial evaluating how well a plant based, liquid solution, cannabidiol (CBD) product made by Greenwich Biosciences called Epidiolex helped to treat drop seizures (the most common seizure type in LGS) and how safe it was compared to placebo.  Two doses (10 mg/kg/day and 20 mg/kg/day) were evaluated compared to placebo.

Author Interviews, Biomarkers, Breast Cancer, Technology, University of Michigan / 16.05.2018

MedicalResearch.com Interview with: Greg Thurber, PhD Assistant Professor Department of Chemical Engineering Assistant Professor Department of Biomedical Engineering University of Michigan  MedicalResearch.com: What is the background for this study? Response: Most current disease screening strategies rely on either blood tests, where the physician can obtain information on specific disease molecules but has no idea where they originated in the body, or anatomical imaging, where the physician can see changes in the structure of tissues but doesn’t have any molecular information. We wanted to develop a method that could provide both molecular information and an image of where these molecules were located. We know from decades of research in cancer that this is a molecular disease, so providing molecular information to the physician will help improve detection and diagnosis. Breast cancer screening provides an excellent opportunity to apply this approach to improve detection. Currently, estimates indicate that we are overspending $4 billion per year on the overdiagnosis and overtreatment of breast cancer because we cannot accurately determine which patients need treatment and which can be safely monitored with no intervention. Despite this problem with overdiagnosis, however, screening saves lives…we simply need a better way. Molecular imaging has the capability of providing both molecular information and the location within the body. However, most of these techniques are expensive and use ionizing radiation, meaning there is a small risk of actually causing cancer. This is not acceptable for screening large numbers of otherwise healthy patients. To avoid this risk and provide a safe, inexpensive, and relatively easy method for patients to undergo screening, we decided to develop near-infrared fluorescent imaging agents that can be taken as a pill. The goal is for the patient to simply take a pill a day or two before their visit, and then the physician shines near-infrared light on the breast tissue to detect tumors where they ‘light up’ by giving off a different color of light.

Author Interviews, Circadian Rhythm, Lancet, Mental Health Research / 16.05.2018

MedicalResearch.com Interview with: Laura Lyall MA; MSc; PhD Research Associate Institute of Health and Wellbeing University of Glasgow MedicalResearch.com: What is the background for this study? Response: Previous studies have suggested a link between disturbed circadian rhythms and depression and bipolar disorder. These studies have however usually used small samples, subjective measures of circadian disruption, or have not accounted for potential confounding factors like sociodemographic and lifestyle characteristics. The UK Biobank cohort has accelerometry (activity monitor) data as well as mental health, lifestyle, BMI and sociodemographic data for over 91,000 individuals, and means we can address this question using objective measures of circadian rhythmicity on a large scale. We derived a measure of relative amplitude from the UK Biobank’s accelerometry data, which was recorded for 7 days between 2013-2014 from around 100,000 participants. Relative amplitude reflects the distinction, in terms of activity levels, between an individual’s most active 10 hours and least active 5 hours, in an average day. If an individual is inactive during the day, or has disturbed sleep at night, the will show low relative amplitude, consistent with disturbed circadian rest-activity patterns. (more…)
Author Interviews, NEJM, Stroke, University Texas / 16.05.2018

MedicalResearch.com Interview with: Dr. S. Claiborne "Clay" Johnston MD, PhD Dean Vice President for Medical Affairs Frank and Charmaine Denius Distinguished Dean’s Chair Dell Medical School The University of Texas at Austin MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior studies have shown that the risk of a stroke or other ischemic events is high in the days to weeks after a TIA or minor stroke. We sought to test whether blocking platelet aggregation more effectively with clopidogrel plus aspirin could reduce this risk compared to aspirin alone.  We found that the combination did reduce risk of major ischemic events.  It also showed a small increase in risk of major hemorrhage, but for most people the benefits would outweigh the potential risk.

MedicalResearch.com Interview with: Dr. Eero Vuoksimaa PhD Institute for Molecular Medicine University of Helsinski Finland MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are many previous reports indicating a positive association between height and cognitive ability but the underlying mechanisms behind this correlation are not well known. We used a mediation model to test if this association is explained by brain size as measured with cortical grey matter size. We found that total cortical surface mediated the relationship between height and cognitive ability. (more…)
Author Interviews, Fertility, JAMA, OBGYNE / 16.05.2018

MedicalResearch.com Interview with: “Acupuncture Needle” by Acid Pix is licensed under CC BY 2.0Caroline Smith, PhD Professor Clinical Research Western Sydney University Research Theme Champion Health and Wellbeing MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Despite technological improvements to IVF the success of IVF treatment remains low. Consequently, new drugs, laboratory techniques and other treatments need to be developed and rigorously tested to explore their effects on producing healthy babies for women undergoing IVF.  In 2002, the first randomised controlled trial of acupuncture administered a specific form of IVF acupuncture at the time of embryo transfer. The results indicated the chance of achieving a pregnancy from acupuncture was twice that to women undergoing IVF treatment alone. From mid 2000s many women have started to use adjunctive treatments such as acupuncture whilst undergoing IVF.  We conducted and reported on a  pilot study in 2006 which produced results suggesting a benefit. It is important that these findings were rigorously examined in a larger trial. Findings are presented from our trial presented in JAMA. Our study of over 800 Australian and New Zealand women undergoing acupuncture treatment during their IVF (in vitro fertilization) cycle has failed to confirm significant difference in live birth rates.

MedicalResearch.com Interview with: “E-Cigarette/Electronic Cigarette/E-Cigs/E-Liquid/Vaping” by Vaping360 is licensed under CC BY 2.0Wei Bao, MD, PhD Assistant Professor Department of Epidemiology, College of Public Health, University of Iowa, Iowa City, IA 52242  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Although the health effects of e-cigarettes remains unclear, e-cigarettes have been marketed as an approach for smoking cessation. Previous studies have reported an increase in e-cigarette use in US people since 2010. The current study showed that from 2014 to 2016, there was an increase in ever use of e-cigarettes but decline in current use of e-cigarettes.  (more…)
Author Interviews, JAMA, OBGYNE / 16.05.2018

MedicalResearch.com Interview with: Dr. Cande V. Ananth, PhD, MPH Adjunct professor Department of Health Policy and Management Mailman School of Public Health Columbia University, NY MedicalResearch.com: What is the background for this study? Response: Preterm delivery rates have declined between 2005 and 2014 in the US and in several European countries. Since reductions in preterm and early term deliveries, and perinatal mortality remain a global health priority, determining the relationship between gestational age distribution and perinatal mortality, remains a challenge. Efforts expended to a more complete understanding of the impact of new interventions, policies, and practices on reducing the burden of early deliveries, and in turn improvements in perinatal survival will be of tremendous benefit for clinical management and care of women during their pregnancy and the newborn.

MedicalResearch.com Interview with: Craig M. Hales, MD, MPH, MS CDR, U.S. Public Health Service Division of Health and Nutrition Examination Surveys National Center for Health Statistics Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Monitoring trends in prescription medication use among children and adolescents is an important part of understanding the health of youth in the U.S. and the healthcare they receive. For this study we used data from the National Health and Nutrition Examination Survey or NHANES, which is a nationally representative survey of the US population and as part of this face-to-face survey in the home, we ask participants about their prescription medication use in the last 30 days and collect information about the prescription directly from the medication package.

Author Interviews, Infections / 15.05.2018

MedicalResearch.com Interview with: Dr. Tom Lodise PharmD, Professor Albany College of Health Sciences, NY  MedicalResearch.com: What is the background for this study? Response: P. aeruginosa (PSA) is intrinsically resistant to many commercially available antibiotics and also has a remarkable capacity to develop resistance to commonly used antibiotics like carbapenems, aminoglycosides, and fluoroquinolones. The terms ‘multidrug resistant’ (MDR) and ‘pan-drug resistant’ are often used to characterize the different patterns of multiple drug resistance exhibited by PSA. Patients with MDR-PSA infections are at an increased risk for delayed receipt of appropriate antimicrobial therapy and ample studies indicated that receipt of delayed appropriate therapy results in substantial increases in morbidity, mortality, and healthcare resource utilization. Although risk factors for these types of infections have previously been identified in the literature, this study takes identification of risk factors further, and develops two clinical risk scores to estimate the probabilities of carbapenem and extensively beta-lactam non-susceptibility among hospitalized, adult patients with PSA infections based on covariates available on clinical presentation. We focused on these two PSA non-susceptible phenotypes as they represent infections at high risk of delayed appropriate therapy due to resistance against the current commonly prescribed empiric anti-pseudomonal antibiotics.

Author Interviews, Cancer Research, JAMA, Yale / 15.05.2018

MedicalResearch.com Interview with: Jeremy O'Connor, MD Section of General Internal Medicine Department of Internal Medicine Postdoctoral Fellow, National Clinician Scholars Program Yale University MedicalResearch.com: What is the background for this study?   Response: There has been a lot of enthusiasm for the use of novel therapies in cancer care, and in particular for novel anticancer agents known as immune checkpoint inhibitors. But very little is known about how quickly providers have adopted immune checkpoint inhibitors into clinical practice. Existing studies suggest, in fact, that the process of clinical adoption is slow, with conventional wisdom holding that it takes an average of 17 years for new evidence to change practice. Our study evaluated whether the adoption of novel therapies might be much faster in certain contexts with the early use of immune checkpoint inhibitors as a notable example. (more…)
Author Interviews, Kidney Stones, Microbiome, Urology / 15.05.2018

MedicalResearch.com Interview with: Gregory Tasian MD, MSc, MSCE Assistant Professor of Urology and Epidemiology University of Pennsylvania Perelman School of Medicine Division of Urology and Center for Pediatric Clinical Effectiveness The Children’s Hospital of Philadelphia MedicalResearch.com: What is the background for this study? What are the main findings? Response:  We found that five classes of commonly prescribed antibiotics were associated with an increased risk of kidney stones. These classes were sulfa drugs (e.g. Bactrim), fluoroquinolones (e.g. Cipro), cephalosporins (e.g. cephalexin), nitrofurantoin, and broad-spectrum penicillins (e.g. augmentin).  For those five classes of antibiotics, the greatest risk was found among younger patients. However, the increased risk was still significant across all ages, including for older adults with the exception of broad-spectrum penicillins, which were not associated with an increased risk of kidney stones among patients >75 years of age. We conducted this study because: 1) Prior investigations have demonstrated that changes in the gut microbiome were associated with kidney stones, 2) Antibiotics are prescribed frequently, and 3) The number of people affected by kidney stone disease has increased 70% over the last 30 years and the greatest increases have been found among children and adolescents. Our results were consistent with these previous studies, so we were not surprised with the findings although we did not know which specific classes of antibiotics would be associated with an increased risk of stones and which ones would not.

Author Interviews, Global Health, JAMA, Pulmonary Disease, Technology / 15.05.2018

MedicalResearch.com Interview with: Michael Hawkes MD PhD Adjunct Professor Assistant Professor Pediatrics, Faculty of Medicine School of Public Health University of Alberta MedicalResearch.com: What is the background for this study? What are the main findings?
  • Pneumonia is the leading cause of mortality in children globally.
  • Oxygen is an essential therapy for children with hypoxemic pneumonia, but is not available in many resource-limited and rural areas.
  • Our innovation, solar powered oxygen delivery, harnesses freely available sun and air to delivery oxygen to patients independent of grid electricity.
  • We performed a randomized controlled trial of solar powered oxygen delivery, compared to standard oxygen delivery using compressed oxygen cylinders in children with hypoxemia hospitalized at two centres in Uganda.
  • Solar powered oxygen was non-inferior to cylinder oxygen with respect to clinical outcomes, and offers advantages in terms of reliability, simplicity, and cost.

Alzheimer's - Dementia, Author Interviews, Personalized Medicine, University of Pennsylvania / 15.05.2018

MedicalResearch.com Interview with: David A. Wolk, MD Associate Professor Department of Neurology Co-Director, Penn Memory Center Associate Director, Alzheimer’s Disease Core Center University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mild Cognitive Impairment (MCI) is a state when individuals have mild memory problems, but not enough to impact day-to-day function.  Many patients with MCI are on the trajectory to developing Alzheimer’s Disease dementia, but about half will not and remain stable.  As such, patients with MCI are often uncertain about the likelihood they should expect to decline in the future which obviously may be associated with considerable anxiety and this may delay opportunities for them to plan for the future or begin therapeutic interventions. This study examined the degree to which amyloid PET, which detects the amyloid pathology of Alzheimer’s Disease, a measure of shrinkage of the hippocampus with MRI, and cognitive measures predicted development of dementia over 3 years.  We found that each of these measures enhances prediction of whether an individual will or will not develop dementia in the future.  If all of these measures are positive, one has a very high risk of progression whereas if amyloid PET and the MRI measurement are normal, there is very little risk of progression.

MedicalResearch.com Interview with: “Big Lunch Extras Reading” by Big Lunch Extras is licensed under CC BY 2.0Scott E. Hadland, MD, MPH, MS Assistant Professor of Pediatrics | Boston University School of Medicine Boston Medical Center Director of Urban Health & Advocacy Track | Boston Combined Residency Program Boston, MA 02118 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous pharmaceutical companies have received media attention for their role in promoting opioid prescribing through speaker programs and other marketing plans in which large-value payments are given to a small number of doctors to promote opioids. In our study, we sought to tell the other side of the story. We wanted to identify whether low-value marketing, including industry-sponsored meals, which are commonplace in the US, were associated with increased opioid prescribing. We found that 1 in 14 doctors received opioid marketing from pharmaceutical companies in 2014, and those that received marketing prescribed 9% more opioids the following year. With each additional meal a doctor received, he or she prescribed more and more opioids the following year. Our sample included 43% of the active physician workforce in the US, suggesting how widespread and far-reaching this effect might be. (more…)
Accidents & Violence, Author Interviews, Pediatrics, Pediatrics / 14.05.2018

MedicalResearch.com Interview with: “Crime Scene _MG_4847” by thierry ehrmann is licensed under CC BY 2.0Daniel Romer, PhD Research Director Annenberg Public Policy Center and Director of its Adolescent Communication Institute (ACI) University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: We have been studying the steady increase in gun violence that has been occurring in popular PG-13 movies since the new rating was adopted in 1984.  It has recently even surpassed the amount of gun violence in R-rated movies.  Since these movies are open to the public at any age, we are concerned that they promote the use of guns and potentially socialize youth to believe that using guns to defend oneself is an appropriate way to handle threats and other conflicts. We knew that the rating requires the omission of graphic consequences, such as blood and suffering, that can make the violence more acceptable.  But we also wondered whether the motivation for the violence might make a difference as well.  Many of the characters in PG-13 movies are seen as heroic (e.g., Bruce Willis and Liam Neeson).  Could that also be a factor that makes such films more acceptable to parents despite their concerns about their children seeing so much violence in the movies.  So, we conducted this experiment to see if parents are less upset by justified violence in PG-13 style movies.  (more…)
Author Interviews, Hip Fractures, Orthopedics, Osteoporosis / 14.05.2018

MedicalResearch.com Interview with: “Just a hairline fracture...” by Gloria Bell is licensed under CC BY 2.0Brittany Bindon, MD Department of Internal Medicine University of Chicago Chicago, Illinois MedicalResearch.com: What is the background for this study? Response: Bisphosphonates are commonly used in the treatment of osteoporosis, however, they have been associated with rare, severe side effects such as osteonecrosis of the jaw and atypical femoral fractures. As a result, bisphosphonate drug holidays have become common in clinical practice though currently, there are minimal data on the safe duration of these drug holidays. We sought to further characterize the clinical and laboratory parameters associated with increased fracture risk in patients on bisphosphonate drug holiday. (more…)

MedicalResearch.com Interview with: “Faecal Coliforms analysis” by SuSanA Secretariat is licensed under CC BY 2.0Dr. Mahiben Maruthappu Public Health Registrar MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gender disparities in the fields of science and technology have been documented, and  it becomes increasingly apparent at higher levels of seniority. In this analysis, we found a quantifiable difference in cancer research funding awarded to female principle investigators compared to male principle investigators (PIs). Across all cancer research funding grants that we identified, male PIs received 3.6 times the total investment value, and 1.6 times the average award value compared with their female counterparts.  (more…)
Author Interviews, Depression, Exercise - Fitness / 13.05.2018

MedicalResearch.com Interview with: “gym” by FooJFoo is licensed under CC BY-NC-ND 3.0Mr. Brett R. Gordon, M.Sc. Postgraduate researcher Physical Education and Sport Sciences Department University of Limerick, Ireland.  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Depression is prevalent, burdensome, and often comorbid mood disorder that is associated with other poor health outcomes. Exercise training interventions have demonstrated comparable efficacy for depressive symptoms to frontline treatments, such as antidepressant medications and behavioral therapies. However, the evidence to date has primarily focused on findings from studies of aerobic exercise training like jogging, running, and cycling. Our work is the first quantitative summary of the effects of resistance exercise training (RET), or weight lifting and strength training, on depressive symptoms, and the influence of variables like participant characteristics, features of the RET, and the methods that were used in studies on the antidepressant effects of RET. The main finding was that resistance exercise training significantly reduced depressive symptoms among adults regardless of their health status, the total prescribed volume of RET (e.g., how much the participants were supposed to exercise), or whether or not strength was significantly improved by the RET intervention.  (more…)
