Author Interviews, Endocrinology, JAMA / 19.09.2017

MedicalResearch.com Interview with: Arjola Bano, MD, MSc, DSc Researcher in the Departments of Internal Medicine and Epidemiology, Erasmus Medical Center, Rotterdam the Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Thyroid function is clinically defined by the measurements of serum thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels. So far, abnormal TSH and FT4 levels as well as variations within the normal range have been linked to an increased risk of cardiovascular disease and death. However, it remains unclear whether there are differences in life span and years of life lived with and without cardiovascular disease, within the reference range of thyroid function. To investigate this, we performed a prospective study among 7785 middle-aged and elderly people with normal thyroid function. Participants were part of the Rotterdam Study, 65 years on average and 52% females. In our statistical analyses, we accounted for sociodemographic and cardiovascular risk factors. Over a median follow-up of 8.1 years, 789 incident cardiovascular deaths and 1357 deaths occurred. Analyses were performed separately among men and women. Our study found differences in life expectancy within the reference range of thyroid function. At the age of 50 years, people with low-normal thyroid function lived up to 3.5 years longer than those with high-normal thyroid function. Also, people with low-normal thyroid function lived a longer life without cardiovascular disease than those with high-normal thyroid function. (more…)
Author Interviews, Diabetes, Geriatrics, Primary Care / 19.09.2017

MedicalResearch.com Interview with: Matthew L. Maciejewski, PhD Professor in Medicine Division of General Internal Medicine, Department of Medicine Center for Health Services Research Primary Care Durham VA Medical Center Duke University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Treating diabetes requires balancing the risks of long-term harm from under-treatment with the short-term and long-term harm from potential over-treatment. Randomized trials have shown that the benefits of aggressive glycemic control only begin after at least 8 years of treatment. Yet, the harms of aggressive glycemic control –  hypoglycemia, cardiovascular events, cognitive impairment, fractures, and death – can happen at any time. In some older people, “deintensification” of diabetes treatment may be the safer route, because of the risks that come with too-low blood sugar. The American Geriatrics Society (AGS) specifically states that medications other than metformin should be avoided when an older patient’s hemoglobin A1c is less than 7.5%, because the risks of hypoglycemia are larger and the potential benefits of treatment are smaller for older adults with diabetes.  Most attention in prior work has focused on undertreatment of diabetes and there has been only limited investigation of patient characteristics associated with overtreatment of diabetes or severe hypoglycemia. Since the elderly are therefore at greatest risk of overtreatment and Medicare is the primary source of care of the elderly, we examined rates of overtreatment and deintensification of therapy for Medicare beneficiaries, and whether there were any disparities in these rates.  We found that almost 11 percent of Medicare participants with diabetes had very low blood sugar levels that suggested they were being over-treated. But only 14 percent of these patients had a reduction in blood sugar medication refills in the next six months. (more…)
Author Interviews, CDC, JAMA, Opiods / 19.09.2017

MedicalResearch.com Interview with: Dr. Deborah Dowell, MD MPH Senior Medical Advisor Division of Unintentional Injury Prevention Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Increases in U.S. life expectancy at birth have leveled off from an average of 0.20 years gained per year from 1970 to 2000 to 0.15 years gained per year from 2000 to 2014. U.S. life expectancy decreased from 2014 to 2015 and is now lower than in most high-income countries, with this gap projected to increase. Drug poisoning (overdose) death rates more than doubled in the United States from 2000-2015; those involving opioids more than tripled. Increases in poisoning have been reported to have reduced life expectancy for non-Hispanic white Americans from 2000-2014. Specific contributions of drug, opioid, and alcohol poisoning to changes in U.S. life expectancy since 2000 were unknown. (more…)
Author Interviews, Emergency Care, Infections, Pediatrics, Technology / 19.09.2017

MedicalResearch.com Interview with: Prof. Alain Gervaix Head of the Emergency Division Department of Children and Adolescents University Hospitals of Geneva Switzerland MedicalResearch.com: What is the background for this study? Response: Many are familiar with the following ‘seemingly’ simple clinical dilemma that occurs on a daily basis across the world. A patient visits the doctor with a fever. Commonly, assigning a diagnosis comes down to deciding whether the infection is bacterial or viral. Accordingly, the doctor decides if to treat or not to treat with antibiotics. The problem is that bacterial and viral infections often present with very similar symptoms, causing uncertainty that leads to antibiotics being used, in many instances, when they are not needed. This antibiotic misuse contributes to the rise of antimicrobial resistance, one of the biggest health threats of the 21st century. Host biomarkers hold great promise as routine diagnostic tools that can assist doctors in making correct antibiotic treatment decisions, as they overcome key limitations of currently applied pathogen-based tests. Recently, a novel host-assay (ImmunoXpert™) for differentiating bacterial from viral infections was developed and validated to yield high sensitivity and specificity. The three-protein host-assay comprises tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), Interferon gamma-induced protein-10 (IP-10) and C-reactive protein (CRP). (more…)
Author Interviews, Exercise - Fitness, JAMA, Mental Health Research, Pediatrics / 19.09.2017

MedicalResearch.com Interview with: Michael Alosco, PhD NRSA Postdoctoral Fellow Boston University Alzheimer’s Disease & CTE Center Boston University School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: TThe goal of this study was to investigate whether playing youth tackle football, particularly before the age of 12, is associated with worse emotional, behavioral, and cognitive difficulties later in life. Participants in this study included 214 former amateur and professional American football players who were part of the LEGEND study at Boston University. Participants had an average age of 51. 43 played high school football, 103 played college football, and there were 68 professional American football players. The former players were divided into two groups: those who began playing tackle football before age 12 and those who began at age 12 or older. Participants received telephone-administered cognitive tests and completed online measures of depression, behavioral regulation, apathy, and executive functioning, such as initiating activity, problem-solving, planning, and organization. Results from former players who started playing tackle football before the age of 12 were compared to those of participants who started playing at age 12 or later. The study showed that participation in tackle football before age 12 increased the odds for having problems with behavioral regulation, apathy and executive functioning by two-fold and increased the odds for clinically elevated depression scores by three-fold. These findings were independent of the total number of years the participants played football or at what level they played, such as high school, college, or professional. Even when a specific age cutoff was not used, younger age of exposure to tackle football corresponded with worse clinical status. (more…)

MedicalResearch.com Interview with: Paz Lopez-Doriga Ruiz MD, PhD candidate Norwegian Institute of Public Health Department of Non Communicable Diseases OsloPaz Lopez-Doriga Ruiz MD, PhD candidate Norwegian Institute of Public Health Department of Non Communicable Diseases Oslo  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Some case reports have linked pandemic influenza to the development of type 1 diabetes. Other studies have suggested that also respiratory infections may contribute to type 1 diabetes risk.  Our findings supports a suggested role of respiratory infections in the etiology of type 1 diabetes and influenza virus could be a contributing factor to the development of clinical diabetes, due to stress and inflammation in predisposed individuals.

Accidents & Violence, Author Interviews, JAMA / 19.09.2017

MedicalResearch.com Interview with: Professor Michael Siegel, MD, MPH Department of Community Health Sciences Boston University School of Public Health Boston, MA 02118 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Each year, more than 1,800 people in the U.S. are killed by their intimate partners. Approximately half of these homicides are committed using firearms. While federal law prohibits people subject to domestic violence restraining orders from possessing firearms, there is no requirement that they surrender guns already in their possession. To close this loophole, several states have enacted laws that not only prohibit gun possession by people subject to restraining orders, but which also explicitly require that they relinquish weapons that they already have. If you are unclear as to the laws of your state, then you should contact a local law firm, such as this nyc lawyer, to discuss your current circumstances. In this study, we investigated the impact of state domestic violence-related firearm laws and rates of intimate partner homicide, using data from all 50 states over a 25-year period, 1991-2015.

Annals Internal Medicine, Author Interviews, Exercise - Fitness, Heart Disease / 19.09.2017

MedicalResearch.com Interview with: Kevin M. Harris, MD Director, Fellowship Training; Director, Echocardiography Allina Health, Minnesota MedicalResearch.com: What is the background for this study? What are the main findings? Response: Triathlon is a popular endurance sport which combines swimming, bicycling and running. We investigated the death rate in the triathlon since its inception in the United States in 1985 through 2016. Specifically we were able to look at the rate of death in USAT races from 2006 to 2016. We identified 135 deaths/cardiac arrests over the time period. 85% of victims were male and victims averaged 47 years. Most deaths and cardiac arrests occurred in the swim. 15 of the deaths were traumatic occurring during the bike portion. The rate of death was 1.74 per 100,000 participants. The death rate was significantly higher for males than females and increased significantly for men > 40 years. On autopsy, nearly half of those victims were found to have significant cardiovascular disease. (more…)
Author Interviews, JAMA, OBGYNE, Pediatrics, Smoking / 19.09.2017

MedicalResearch.com Interview with: Filippos Filippidis MD MPH PhD Lecturer in Public Health School of Public Health Imperial College London London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Smoking kills millions of people every year. It is well established that increasing tobacco prices is the most effective way to reduce tobacco consumption and hence mitigate the devastating effects of tobacco on health. Taxation on tobacco products is high in the European Union, which makes cigarettes less affordable. However, transnational tobacco companies are known to manipulate prices, ensuring that cheap or ‘budget’ cigarettes are still available. This is particularly important for younger smokers and those of low socioeconomic status who are more sensitive in price increases. Smoking during pregnancy, as well as exposure of pregnant women and babies to cigarette smoke increase infant mortality. There is also evidence that increasing tobacco prices is associated with lower infant mortality. However, researchers typically use average or premium cigarette prices. We analysed 54 million births from 23 European Union countries to see if the differential between average priced and budget cigarettes (i.e. the availability of cigarettes much cheaper than average priced ones) is associated with infant mortality. We found that increasing average cigarette prices by 1 Euro per pack was associated with 0.23 fewer deaths per 1,000 live births in the same year and an additional 0.16 fewer deaths per 1,000 live births in the following year. A 10% increase in the price differential between budget and average priced cigarettes was associated with 0.07 more deaths per 1,000 live births the following year. This means that 3,195 infant deaths could potentially have been avoided in these 23 countries if there was no price difference between cigarette products over the 10-year study period. (more…)
Author Interviews, Cancer Research, Stroke / 15.09.2017

MedicalResearch.com Interview with: Dr Jacobo Rogado Medical oncology fellow Hospital de La Princesa Madrid, Spain MedicalResearch.com: What is the background for this study? Response: Some publications have suggested that there is an association between stroke and the subsequent diagnosis of cancer, although others have not confirmed this. We have addressed this issue with a study conducted at our hospital during two years. We studied a population of about 1000 patients with stroke. We evaluated the incidence of cancer in this population during the follow-up of 18 months, as well as whether there were factors associated with its occurrence. (more…)
Author Interviews, Compliance, Diabetes / 15.09.2017

MedicalResearch.com Interview with: Alexander Turchin, MD, MS Director of Quality in Diabetes in the Division of Endocrinology, Diabetes and Hypertension Brigham and Women's Hospital  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Anecdotally, many clinicians report that their patients with diabetes frequently decline recommendations to start treatment with insulin. However, until now, there was no systematic information available on this phenomenon. Our study has found that 30% of patients initially decline their healthcare providers’ recommendation to start insulin therapy. Patients who do ultimately start treatment with insulin, do it on average more than two years after initially declining it. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Heart Disease, JAMA / 15.09.2017

MedicalResearch.com Interview with: Hans Kirkegaard, MD, PhD, DMSci, DEAA, DLS Research Center for Emergency Medicine and Department of Anesthesiology and Intensive Care Medicine Aarhus University Hospital and Aarhus University Aarhus, Denmark  MedicalResearch.com: What is the background for this study? Response: In 2002, two landmark studies demonstrated that mild therapeutic hypothermia (now known as targeted temperature management, TTM) for 12 or 24 hours improves neurological outcome in adult comatose patients suffering from out of hospital cardiac arrest. Accordingly, international guidelines now recommend TTM for at least 24 hours in this patient group. However, there are no studies, only case reports that explore the effect of prolonged cooling. We therefore wanted to set up a trial that could fill out this knowledge gap, we hypothesized that doubling the hypothermia dose to 48 hour would improve neurological outcome without increasing the risk of adverse events considerably.

Author Interviews, Diabetes, Weight Research / 15.09.2017

MedicalResearch.com Interview with: Dr Nita Forouhi, MRCP, PhD, FFPHM Programme Lead & Consultant Public Health Physician MRC Epidemiology Unit, University of Cambridge School of Clinical Medicine Institute of Metabolic Science Cambridge Biomedical Campus, Cambridge MedicalResearch.com: What is the background for this study? Response: Past research has shown a beneficial link between some dairy products and risk of developing type 2 diabetes, but the mechanisms are not well understood. Body composition (total fat and lean mass) has been suggested as one pathway for the link, but the distribution of body fat and lean mass in relation to dairy consumption is not well studied. Based on this research gap, we aimed to investigate associations between types of dairy consumption and markers of body fat and lean mass distribution including: peripheral fat, the ratio of visceral (fat that surrounds the body organs) to abdominal subcutaneous fat (fat that accumulates under the skin) and appendicular lean mass (i.e., in the limbs).

Author Interviews, Critical Care - Intensive Care - ICUs, Infections, JAMA / 15.09.2017

MedicalResearch.com Interview with: Dr. Chanu Rhee MD, Assistant Professor Therapeutics Research and Infectious Disease Epidemiology Group Department of Population Medicine at Harvard Medical School / Harvard Pilgrim Health Care Institute Critical Care and Infectious Disease Physician Transplant/Oncology Infectious Disease service and Medical Intensive Care Unit at Brigham and Women’s Hospital  MedicalResearch.com: What is the background for this study? Response: Multiple studies suggest that the incidence of sepsis, the syndrome of life-threatening organ dysfunction caused by infection, is increasing over time, while mortality rates are decreasing.  However, reliably measuring sepsis incidence and trends is challenging because clinical diagnoses of sepsis are subjective and insurance claims data, the traditional method of surveillance, can be affected by changing diagnosis and coding practices over time. In this study, my colleagues and I estimated the current U.S. burden of sepsis and trends using clinical data from the electronic health record systems of a large number of diverse hospitals. The findings, published in JAMA, challenge the use of claims data for sepsis surveillance and suggest that clinical surveillance using electronic health record data provides more objective estimates of sepsis incidence and outcomes.

Author Interviews, Boehringer Ingelheim, Columbia, Heart Disease, J&J-Janssen, Merck, NEJM / 14.09.2017

MedicalResearch.com Interview with: Professor Christopher P. Cannon MD Executive Director, Cardiometabolic Trials, Baim Institute Cardiologist Brigham and Women's Hospital Baim Institute for Clinical Research Columbia University College of Physicians and Surgeons MedicalResearch.com: What is the background for this study? What are the main findings? Response: The trial explored whether a dual therapy approach of anticoagulation and P2Y12 antagonist - without aspirin - in non-valvular atrial fibrillation (AF) patients following percutaneous coronary intervention (PCI) and stent placement would be as safe, and still efficacious, as the current standard treatment – triple therapy. For more detailed background on the study, readers may want to review the first paragraph of the article in the New England Journal of Medicine. Results showed significantly lower rates of major or clinically relevant non-major bleeding events for dual therapy with dabigatran, when compared to triple therapy with warfarin. In the study, the risk for the primary safety endpoint (time to major or clinically relevant non-major bleeding event) was 48 percent lower for dabigatran 110 mg dual therapy and 28 percent lower for dabigatran 150 mg dual therapy (relative difference), with similar rates of overall thromboembolic events.

Author Interviews, Infections, NEJM / 14.09.2017

MedicalResearch.com Interview with: Susan E. Dorman, M.D Associate Professor of Medicine, Division of Infectious Diseases Johns Hopkins University School of Medicine, Baltimore MedicalResearch.com: What is the background for this study? What are the main findings? Response: Tuberculosis, also called “TB” is one of the top 10 causes of death worldwide, according to the World Health Organization.  TB is caused by bacteria called Mycobacterium tuberculosis.  In 2015, over 10 million people became sick from TB and 1.8 million people died from TB.  This is a lot of people – diagnosing and treating TB to improve their health is important.  Because TB usually involves the lungs, it can be passed from person to person through the air, and thus, diagnosing and treating TB is critical to  reduce the spread of TB.   Drug-resistant TB -- TB caused by bacteria that are resistant to commonly used TB antibiotics -- is a serious problem.  In 2015 an estimated 480,000 people had multidrug-resistant TB. We have been working to develop better, faster ways to diagnose TB and drug-resistant TB.  A new test was developed as a partnership between Rutgers University and Cepheid (Sunnyvale, CA), and development was supported by the US National Institutes of Health (NIH).  The new test was designed to detect Mycobacterium tuberculosis bacteria in sputum, and to simultaneously detect whether the bacteria are resistant to several of the main antibiotics (isoniazid, fluoroquinolones, and aminoglycosides) used to treat TB.  The test takes about two hours from sample to result. The NEJM article describes the results of a study that was undertaken in China and South Korea to understand how well the new test works, compared against gold standard tests. (more…)
Author Interviews, Cancer Research / 14.09.2017

MedicalResearch.com Interview with: Ezra Cohen, MD Associate Director, Moores Cancer Center Professor of Medicine Moores Cancer Center UC San Diego Health - La Jolla Moores Cancer Center La Jolla, CA  92093 MedicalResearch.com: What is the background for this study? Response: We have known for a couple of years that anti-PD1 therapy, and specifically pembrolizumab, is active in  head and neck squamous cell carcinoma (HNSCC). The KN40 trial now tested pembrolizuamb against standard of care in patients whose cancers progressed on platinum containing regimens. MedicalResearch.com: What are the main findings? Response: The main findings really supported what we know about pembrolizumab in this disease - it is active and effective with a favorable side effect profile. Pembrolizumab reduced the risk of death by 19% and was associated with a 14% response rate. The effect was even greater in tumors that expressed PDL1 and, in the highest expressing group, the benefit in reduction of risk of death was 46% with a 27% response rate. (more…)
Author Interviews, Melanoma, NEJM / 14.09.2017

MedicalResearch.com Interview with: Dr Alexander Menzies BSc(Med) MBBS (Hons) FRACP PhD Medical Oncologist and Senior Research Fellow at Melanoma Institute Australia The University of Sydney and Royal North Shore and Mater Hospital  MedicalResearch.com: What is the background for this study? Response: For early-stage melanoma, surgical resection is the standard treatment and is associated with an excellent long-term prognosis. However until now, Stage III melanoma patients (where the disease has spread to the lymph nodes) who have had their tumours surgically removed have simply had to play the waiting game to see if their melanoma would metastasise, with many ultimately dying of the disease. Checkpoint inhibitor immunotherapies and drugs that target the mitogen-activated protein kinase (MAPK) pathway have improved the outcome of patients with metastatic melanoma, but their role as adjuvant therapy is still being actively investigated. Prior Phase III trials (COMBI-D and COMBI-V) have shown improved overall survival in patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations. At Melanoma Institute Australia, we were keen to see if this improvement would be seen in the adjuvant setting also. This clinical trial was the first in the world to give targeted therapy to melanoma patients at an earlier stage of the disease to prevent spread and recurrence. (more…)
Abuse and Neglect, Artificial Sweeteners, Diabetes / 14.09.2017

MedicalResearch.com Interview with: Dr. Richard L. Young PhD Associate Professor Adelaide Medical School The University of Adelaide Group Leader, Intestinal Nutrient Sensing Group Centre for Nutrition & Gastrointestinal Diseases South Australian Health & Medical Research Institute North Terrace, Adelaide | SA MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study was a clinical trial in healthy subjects dosed a sweetener combination (sucralose and acesulfame-K) at a  dose to equal 1.5 L of artificial sweetened drink per day. This was given in capsules to dissolve in the proximal intestine (3 capsules per day, 2 weeks) and was a randomised, placebo-controlled double-blind study. Sweetener treatment increased glucose absorption (assessed by serum 3-O-methy glucose), increased glycemic responses to duodenal glucose infusion and decreased GLP-1 responses. These data show that intake of these sweeteners in healthy subjects may increase glycemic responses, and are the first to document an effect of these sweeteners to increase glucose absorption in humans.

Author Interviews, Heart Disease, NEJM, Stroke, Surgical Research / 13.09.2017

MedicalResearch.com Interview with: Prof. Jean-Louis MAS Université Paris Descartes INSERM UMR S 894 Service de Neurologie et Unité Neurovasculaire Hôpital Sainte-Anne Paris  MedicalResearch.com: What is the background for this study? Response: Stroke is a major cause of death, disability and dementia affecting 17 million people each year worldwide. About 80% of strokes are ischemic strokes due to occlusion of a cerebral artery by a thrombus, itself the consequence of various arterial or heart diseases. In 30 to 40% of cases, no definite cause of ischemic stroke can be identified. Cryptogenic stroke is the term used to refer to these strokes of unknown etiology. The patent foramen ovale (PFO) is a defect between the upper two heart chambers (called atria) though which a thrombus of venous origin may reach the systemic circulation and cause a stroke. This mechanism is called paradoxical embolism. Several case-control studies have shown an association between PFO and cryptogenic ischemic stroke, particularly in patients less than 60 years old, in those who have an atrial septal aneurysm (defined as an abnormal protrusion of the interatrial septum in the right or the left atrium or both) in addition to a PFO, and in those who have a PFO with a large right-to-left shunt. These findings suggested that a PFO might be responsible for stroke and that PFO closure with a device may decrease the risk of stroke recurrence. However, the causative relationship between PFO and stroke and the best strategy to prevent stroke recurrence have long been a hot topic of debate. Three previous randomized clinical trials failed to demonstrate any superiority of PFO closure over antithrombotic therapy. (more…)

MedicalResearch.com Interview with: Dr. Jay Edelberg MD, PhD VP Head of Cardiovascular Development and Head Global Cardiovascular Medical Affairs Sanofi  MedicalResearch.com: What should readers take away from the data that Sanofi and Regeneron is presenting at ESC Congress 2017?    Response: This year at European Society of Cardiology (ESC,) we are pleased to present analyses that further demonstrate additional efficacy and tolerability of Praluent (alirocumab). While statins remain the first-line treatment, Praluent has shown a consistent benefit as an additional therapy to high-intensity statins in patients with clinical atherosclerotic cardiovascular disease (ASCVD) and/or heterozygous familial hypercholesterolemia (HeFH), allowing many patients to achieve low-density lipoprotein (LDL) cholesterol levels previously considered unattainable in this patient population. Our data further emphasize the need for additional cholesterol-lowering options in these high cardiovascular (CV) risk patient populations, including individuals living with diabetes.   (more…)
Author Interviews, CDC, Education, Pediatrics / 13.09.2017

MedicalResearch.com Interview with: Catherine N. Rasberry, PhD Health Scientist, Division of Adolescent and School Health CDC Atlanta MedicalResearch.com: What is the background for this study? What are the main findings? Response: For many years, researchers have documented links between health-related behaviors and educational outcomes such as letter grades, test scores, and other measures of academic achievement. However, many of those studies are becoming out-of-date or have used samples that were not nationally representative. The aim of this study was to see if previous findings held in a current, national sample of high school students. Consistent with previous studies, our findings revealed that regardless of sex, race/ethnicity and grade-level, high school students who received mostly A’s, mostly B’s, or mostly C’s had higher levels of most protective health-related behaviors and lower levels of most health-related risk behaviors. For example, we found that:
  • Students who reported receiving mostly Ds and Fs, were nine times more likely than students who received mostly As to report having ever injected any illegal drugs.
  • Also, students who reported receiving mostly Ds and Fs were more than four times more likely than students who received mostly As to report that they had four or more sexual partners.
  • Conversely, students who reported receiving mostly As were twice as likely as students who received mostly Ds and Fs to report eating breakfast every day in the past week.

Author Interviews, Brigham & Women's - Harvard, Endocrinology, Hormone Therapy, JAMA, Menopause / 13.09.2017

MedicalResearch.com Interview with: JoAnn E. Manson, MD, DrPH Chief, Division of Preventive Medicine Brigham and Women's Hospital Professor of Medicine and the Michael and Lee Bell Professor of Women's Health Harvard Medical School Boston, Massachusetts  02215  MedicalResearch.com: What is the background for this study? Response: The current report provides new information on total mortality and the rates of death from specific causes (cardiovascular disease, cancer, other major illnesses) over 18 years of follow-up in the Women’s Health Initiative (WHI) randomized trials of hormone therapy (estrogen + progestin and estrogen alone). This is the first WHI report to focus on all-cause and cause-specific mortality. It includes all of the 27,347 women in the 2 hormone therapy trials with >98% follow-up over 18 years, during which time 7,489 deaths occurred. This is more than twice as many deaths as were included in earlier reports. The report also provides detailed information on differences in results by age group (ages 50-59, 60-69, 70-79) at time of study enrollment. (more…)

Farland, ScD Assistant Director of Epidemiologic Research Center for Infertility and Reproductive Surgery Brigham and Women's Hospital | Harvard Medical School Instructor | Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Endometriosis is chronic gynecologic condition that affects approximately ten percent of women. Women with endometriosis can experience painful menstrual periods, general chronic pelvic pain, and pain associated with intercourse. Currently we know very few modifiable risk factors for endometriosis. (more…)
Author Interviews, Cannabis / 13.09.2017

MedicalResearch.com Interview with: Benjamin Hansen, Keaton Miller, Caroline Weber Department of Economics University of Oregon MedicalResearch.com: What is the background for this study? Response: Recreational marijuana is now, or will soon be, legally available to 21% of the United States population after they follow in Canada's path. All around Canada people can buy marijuana on an online dispensary canada legally with no repercussions but a major concern among policymakers at all levels of government in the US is the trafficking or "diversion" of marijuana from states where it is legal to other states. Though significant measures are in place to prevent large scale drug trafficking by licensed producers, consumers may easily purchase in one state and travel to a different state for consumption or re-sale. Though this policy concern has existed since medical marijuana became available in the 1990s, the extent of this diversion by consumers has been unknown. With recreational marijuana becoming the norm within the states that have made it legal, although policymakers are worried about the potential for trafficking over state lines, it is still legal for those who which to enjoy their cannabis filled vape carts without any repercussions. The cultivation of marijuana is a completely different topic when it comes to the trafficking of marijuana. Although states like Colorado and Oregon have allowed the cultivation of marijuana for both uses, there are states that have legalized cultivation or at least have it for medical use. This has the effect of businesses like LED Grow Lights HQ growing to supply the growing demand. We take advantage of a unique natural experiment in the Pacific Northwest: Oregon opened a recreational market on October 1, 2015, well after Washington's market opened on July 8, 2014. By examining the sales of Washington retailers along the Washington-Oregon border in the months before and after Oregon's market opened, we can measure the extent to which consumers from Oregon crossed state lines to purchase marijuana in Washington.

Author Interviews, Melanoma, NYU / 13.09.2017

MedicalResearch.com Interview with: Jeffrey Weber, M.D., Ph.D Laura and Isaac Perlmutter Cancer Center New York University Langone Medical Center New York, NY 10016  MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a major unmet need for well tolerated and effective adjuvant therapy for high risk melanoma, that is, melanoma that has been removed but the patients have a 50%+ risk of relapse over 5 years, and a 50%+ risk of death over 10 years from melanoma. Since nivolumab is an active and well tolerated drug in metastatic disease, it seemed reasonable to test it after surgery to prevent recurrence. Since ipilimumab is approved for resected stage III melanoma in the US as adjuvant therapy, that was the control arm for comparison, and that is an active control, which prolongs relapse free and overall survival comared to placebo.

Author Interviews, Lipids, Psychological Science / 12.09.2017

MedicalResearch.com Interview with: Jiah Yoo Ph.D. Student in Social Psychology University of Wisconsin-Madison Madison, WI 53706  MedicalResearch.com: What is the background for this study? Response: A growing number of studies have shown that positive emotions predict better physical health. However, a caveat of these findings is that most studies have been conducted with Western samples. As cultural psychologists, we have learned that European American cultural contexts are particular in that positive emotions are highly valued and emphasized. For example, in East Asian cultures, it is a commonly shared view that positive emotions have some dark sides such as that they are fleeting, may attract unnecessary attention from others, and can be a distraction from focusing on important tasks. Given the cultural differences in emotions, we thought it would be important to test whether the established link between positive emotion and enhanced physical health are relevant to other cultural contexts, such as those in East Asia. We focused on blood lipids profiles, one of the major risk factors for heart diseases, as objective measures of health. Because of the global prevalence of coronary artery diseases, blood lipids are considered important indices of biological health in many Western and East Asian countries. In addition, blood lipids are largely influenced by lifestyles and behavioral factors so we further tested the role of various health behaviors (i.e., dietary habits, body mass index, smoking, alcohol consumption) in the lipids-emotion link in different cultures.

MedicalResearch.com Interview with: Rebecca J. Schmidt, M.S., Ph.D.  Assistant Professor, Public Health Sciences UC Davis California MedicalResearch.com: What is the background for this study? Response: Maternal folic acid taken near conception has been linked to reduced risk for autism in the child in previous studies. Separate studies show that exposure to pesticides during pregnancy is associated with increased risk for autism. Animal studies demonstrate that folic acid and other B-vitamins can attenuate effects of certain environmental contaminants, including pesticides. This case-control study examined combined maternal folic acid and pesticide exposures in relation to autism in the child. (more…)

MedicalResearch.com Interview with: Dr. Bhavini Patel Murthy, MD MPH Division of State and Local Readiness Office of Public Health Preparedness and Response and Epidemic Intelligence Service CDC, Atlanta  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Public health preparedness is critical to ensure national health security. Recurring disasters (both natural and man-made), especially recent weather emergencies in Texas in Florida, have highlighted the need for robust coordination between federal, state, local, territorial and tribal governments to adequately prepare and respond to public health emergencies. The Public Health Emergency Preparedness (PHEP) program provides funding to state, local and territorial governments to prevent, protect, respond, and rapidly recover from large and small public health emergencies. This is the first analysis of preparedness capabilities based on reports from all 62 jurisdictions that receive PHEP funding across the United States and its territories. We found that most jurisdictions had limited preparedness capacity prior to 9/11, but now have made considerable progress. For example, all 62 jurisdictions now report having an incident management infrastructure. (more…)

MedicalResearch.com Interview with: RTISusan G. Haber, Sc.D.  Director, Health Coverage for Low-Income and Uninsured Populations RTI International Waltham, MA 02452-8413 MedicalResearch.com: What is the background for this study? Response: In 2014, the state of Maryland and the federal Centers for Medicare and Medicaid Services (CMS) began testing an alternative payment structure for inpatient and outpatient hospital services. Known as the All-Payer Model, the new system limits hospitals’ revenues from Medicare, Medicaid, and private insurers to a global budget for the year. This builds on Maryland’s hospital rate-setting system that had operated since the 1970s, where all payers pay the same rates. CMS wanted to test whether global budgets could help Maryland limit cost growth and reduce avoidable hospital use. The goal of the model is to limit per capita total hospital cost growth for both Medicare and all payers and to generate $330 million in Medicare savings over 5 years. (more…)
