Author Interviews, Breast Cancer, Brigham & Women's - Harvard, MRI, Surgical Research / 24.06.2016

MedicalResearch.com Interview with: Eva C. Gombos, MD Assistant Professor, Radiology Harvard Medical School Brigham and Women’s Hospital MedicalResearch.com: What is the background for this study? Response: Treatment of early stage breast cancer, breast-conserving therapy (BCT), which consists of lumpectomy followed by whole-breast irradiation, requires re-excision 20 %–40% of patients due to positive margins. Breast MR is the imaging modality with the highest sensitivity to detect breast cancer. However, patients who undergo breast MR imaging have not experienced reduced re-excision or improved survival rates. Our hypothesis is that supine (performed with patient lying on her back) MR imaging within the operating room can be used to plan the extent of resection, to detect residual tumor immediately after the first attempt at definitive surgery, and to provide feedback to the surgeon within the surgical suite. The aim of this study was to use intraoperative supine MR imaging to quantify breast tumor deformation and displacement secondary to the change in patient positioning from imaging (prone performed the patient lying on her stomach) to surgery (supine) and to evaluate the residual tumor immediately after BCT.

Author Interviews, NEJM, Occupational Health, Opiods / 24.06.2016

MedicalResearch.com Interview with: Professor Ellen Meara, PhD Professor The Dartmouth Institute for Health Policy and Clinical Practice MedicalResearch.com: What is the background for this study? Response: Responding to a fourfold rise in death rates, between 2006 and 2012, states collectively enacted 81 laws restricting prescribing and dispensing of prescription opioids. Jill Horwitz, PhD, JD, said “states hoped passing a range of laws might help. So they are enacting small fixes — forbidding patients from “doctor-shopping,” and requiring doctors to use tamper-resistant prescription forms. They are also implementing major efforts such as prescription drug monitoring programs (PDMPs) — online databases that allow law enforcement and clinicians to monitor prescriptions.” (more…)

MedicalResearch.com Interview with: Dr. Ir. Gerda Pot PhD Universitair Docent Gezondheid en Leven| Assistant Professor Health and Life Faculteit Aard- en Levenswetenschappen | Faculty of Earth and Life Sciences MedicalResearch.com: What is the background for this study? Response: I was inspired to start this work by my grandmother. She was a stickler for timekeeping of her meals and I wondered whether this was her secret for healthy aging. It seems common wisdom but surprisingly very little scientific evidence exist. Therefore we conducted this review to see all the studies out there before setting out doing our own research. (more…)
Author Interviews, Cancer, Cancer Research, Nutrition / 23.06.2016

MedicalResearch.com Interview with: Lindsay Kohler MPH Mel and Enid Zuckerman College of Public Health Tucson, Arizona MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several studies have reported that following health promotion guidelines for diet, physical activity, and maintenance of a healthy body weight may reduce the risk of getting cancer or dying from cancer. We performed a systematic review to examine the associations between established cancer prevention guidelines for diet and physical activity and cancer outcomes. We found that adhering to cancer prevention guidelines set forth by the American Cancer Society or the World Cancer Research Fund/American Institute for Cancer Research consistently reduced the risk of overall cancer incidence and mortality (10-61%) in the studies included in this review. In addition, higher adherence to the guidelines consistently reduced the risk of breast, colorectal, and endometrial cancers. Adherence to a pattern of healthy behaviors may significantly reduce cancer incidence and mortality. (more…)
Author Interviews, Heart Disease, JACC, Surgical Research / 23.06.2016

MedicalResearch.com Interview with: Dr. Stefan Toggweiler, MD Heart Center, Luzerner Kantonsspital Lucerne, Switzerland MedicalResearch.com: What is the background for this study? Response: Transcatheter aortic valve replacement (TAVR) is increasingly used for the treatment of aortic stenosis in inoperable and high-risk patients. It is well known that TAVR is associated with acute and delayed occurrence of conduction disorders. Namely, delayed high-degree atrioventrcular block is a feared complication. Thus, patients are usually monitored by telemetry for a few days, but there is currently no consensus on the duration of telemetry. In this study, we evaluated how the postprocedural ECG determines the need for permanent pacemaker implantation in patients undergoing TAVR. (more…)

MedicalResearch.com Interview with: Peter Johnson MA, MD, FRCP Professor of Medical Oncology Cancer Research UK Centre Southampton General Hospital Southampton MedicalResearch.com: What is the background for this study? What are the main findings? Prof. Johnson: Based upon retrospective series looking at the ability of interim PET to predict the outcomes of treatment, we aimed to test the idea of modulating treatment in response to an early assessment of the response to ABVD: could we safely reduce the amount of treatment by omitting bleomycin in the group who had responded well? Although the risk of severe toxicity from bleomycin is generally low, for the small number of patients who experience it, it can be life-changing or even fatal. We also wanted to test whether it might be possible to reduce the use of consolidation radiotherapy by comparison to our previous trials, and this seems to have worked too: we used radiotherapy in less than 10% of patients in RATHL, as compared to around half in our previous trials. We have seen better survival figures than in our previous studies with less treatment overall, so it feels as though we are on the right track. (more…)
Author Interviews, Mental Health Research, Pediatrics, Telemedicine / 23.06.2016

MedicalResearch.com Interview with: Mirna Becevic, PhD, MHA Assistant Research Professor University of Missouri - Department of Dermatology Missouri Telehealth Network MedicalResearch.com: What is the background for this study? Response: Psychiatry is, by far, the biggest utilizer of telemedicine services on the Missouri Telehealth Network (MTN). MTN supports an average of 4000 tele-psychiatry appointments every month, and 10% of those are provided by the University of Missouri Department of Psychiatry. Since we are all aware of the ever-increasing demand for child and adolescent psychiatry, but also the stigma that goes along with it, we wanted to examine more closely the actual usage of those services at the University of Missouri.

MedicalResearch.com Interview with: Sunita Sah MD PhD Management & Organizations Johnson Graduate School of Management Cornell University MedicalResearch.com: What is the background for this study? What are the main findings?  Dr. Sah: Physicians often recommend the treatment they specialize in, e.g., surgeons are more likely to recommend surgery than non-surgeons. Results from an observational study and a randomized controlled laboratory experiment found that when physicians revealed their bias toward their own specialty, patients were more likely to report increased trust in the physician’s expertise and take the treatment in accordance with the physician’s specialty.    (more…)
Author Interviews, Cancer Research, Nature / 23.06.2016

MedicalResearch.com Interview with: Dr Stéphanie Kermorgant PhD Barts Cancer Institute Queen Mary University of London MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is an urgent need to better understand how cancer spreads around the body (a process called metastasis). Often it is metastasis that kills cancer patients and not the primary tumour. During metastasis, cancer cells detach from the primary tumour and are able to survive detached, allowing them to enter in blood vessels and colonize different parts of the body. Integrins and growth factor receptors are two classes of cell surface molecules that have been known to cooperate to promote cancer metastasis. However how they communicate is poorly understood. They have mostly been shown to exert their function at the surface of the cells. Our study reveals that one growth factor receptor, called c-Met, and one integrin, beta1-integrin, in fact communicate inside the cancer cell to increase its survival when detached. Moreover, this communication occurs in an anusual place in the cell, that we have called “Autophagy Related Endomembrane” (ARE). Autophagy is normally a process that degrades and recycles cellular material, making new building blocks for the cell. Our study reveals that intracellular structures related to the autophagy process can also help membrane receptors to communicate. Thus they may also function as “signalling platforms”. One other key finding in this study is that integrins normally have been recognized to function as “adhesion molecules”, connecting the cells to their surrounding environment, the “extracellular matrix”. Their role in metastasis has been mostly linked to their adhesive function. Our exciting study reveals a new function of integrins, a “signalling function”, which is independent from their adhesion function. (more…)

MedicalResearch.com Interview with: Professor Chris Semsarian MBBS PhD MPH FRACP FAHMS FAHA FHRS FCSANZ Professor of Medicine, University of Sydney Cardiologist, Royal Prince Alfred Hospital NHMRC Practitioner Fellow Head, Molecular Cardiology Program Centenary Institute, Newtown NSW Australia MedicalResearch.com: What is the background for this study? Response: Sudden cardiac death is a tragic and devastating event at all ages, and especially in the young (aged under 35 years). Understanding the causes and circumstances of SCD in the young is critical if we are to develop strategies to prevent SCD in the young. Our study represents the first prospective, population-based study of SCD in the young across two nations, Australia and New Zealand. (more…)
Author Interviews, Microbiome, Transplantation / 23.06.2016

MedicalResearch.com Interview with: Maria-Luisa Alegre, MD, PhD Professor of medicine University of Chicago MedicalResearch.com: What is the background for this study? What are the main findings? Response: Most of the research that investigates why/how transplanted organs are rejected has focused on the genetic disparities between the donor and the recipient. Foreign proteins in the donor organ are recognized by the immune system of the host, which becomes activated to reject the transplanted organ. This is why transplant recipients need to take immunosuppressive medications for the rest of their lives. Whether environmental factors, in addition to genetic factors, can also affect how the immune system is activated by the transplanted organ is much less understood. In particular, the microbiota, the communities of microbes that live on and in our body, is distinct in each individual and is known to affect the function of the immune system in diseases ranging from autoimmunity to cancer. Using mouse models of skin and heart transplantation, we investigated if the microbiota was an environmental factor that could affect the speed at which the immune system rejects a transplanted organ. We found that the microbial communities that colonize the donor and the host fine-tune the function of the immune system and control the strength with which the immune system reacts to a transplanted organ.

Anesthesiology, Author Interviews, Cognitive Issues, NYU, Pediatrics, Science / 23.06.2016

MedicalResearch.com Interview with: Guang Yang, Ph.D. Assistant Professor NYU Langone School of Medicine Alexandria Center for Life Sciences New York, NY 10016 MedicalResearch.com: What is the background for this study? How common is the problem of long-lasting behavioral deficits after repeated anesthesia exposure in neonates? Response: Each year, in the United States alone, more than 1 million children under 4 years of age undergo surgical procedures that require anesthesia. Many lines of evidence from animal studies have shown that prolonged or repeated exposure to general anesthesia during critical stages of brain development leads to long-lasting behavioral deficits later in life. The results from human studies are less clear, although some studies suggest a higher incidence of learning disabilities and attention-deficit and hyperactivity disorders in children repeatedly exposed to procedures requiring general anesthesia. To date, there has been no effective treatment to mitigate the potential neurotoxic effects of general anesthesia. (more…)
Alzheimer's - Dementia, Author Interviews, Cost of Health Care, Geriatrics / 22.06.2016

MedicalResearch.com Interview with: Pei-Jung Lin, Ph.D. Assistant Professor Center for the Evaluation of Value and Risk in Health Institute for Clinical Research and Health Policy Studies Tufts Medical Center Boston, MA 02111 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Alzheimer’s disease (AD) is a slow, progressive disease. Many people with AD may live for years with the disease left unrecognized or untreated, in part because the early symptoms are mild and often mistaken as part of normal aging. In this study, we found that Alzheimer’s patients may use more health care services and incur higher costs than those without dementia even before they receive a formal diagnosis. For example, total Medicare expenditures were 42% higher among Alzheimer’s patients than matched controls during the year prior to diagnosis ($15,091 vs. $10,622), and 192% higher in the first year immediately following diagnosis ($27,126 vs. $9,274). We also found similar trends among Medicare patients with mild cognitive impairment (MCI)— a prodromal stage of AD and associated with higher dementia risk. Our study suggests that an Alzheimer’s disease or MCI diagnosis appears to be prompted by other health problems such as cardiovascular and cerebrovascular diseases, pneumonia, renal failure, urinary tract infections, and blood and respiratory infections. This finding likely reflects a failure of ambulatory care related to the impact of cognitive impairment on other chronic conditions. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Heart Disease, JAMA, Pharmacology / 22.06.2016

MedicalResearch.com Interview with: Thomas Andrew Gaziano, MD, MSc Department of Cardiology Assistant Professor Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Heart failure (HF) is the leading cause of admissions to hospitals in the United States and the associated costs run between $24-47 billion annually. Targeting neurohormonal pathways that aggravate the disease has the potential to reduce admissions. Enalapril, an angiotensin converting enzyme-inhibitor (ACEI), is more commonly prescribed to treat HF than Sacubitril/Valsartan, an angiotensin-receptor/neprilysin inhibitor (ARNI). The latter was shown to reduce cardiovascular death and hospitalizations due to heart failure in a multi-country, randomized clinical (PARADIGM-HF), compared to Enalapril. In order to assess the cost-effectiveness of Sacubitril/Valsartan, compared to Enalapril, in the United States, we created a model population with population characteristics equivalent to the population in the PARADIGM-HF trial. Using a 2-state Markov model we simulated HF death and hospitalizations for patients with a left ventricular ejection fraction (LVEF) of 40% or less. (more…)
Author Interviews, BMJ, Brigham & Women's - Harvard, Nutrition, Prostate Cancer / 22.06.2016

MedicalResearch.com Interview with: Dr. Ying Bao Sc.D., M.D Assistant Professor of Medicine Channing Division of Network Medicine Department of Medicine Brigham and Women's Hospital Harvard Medical School, Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nuts are rich in bioactive macronutrients, micronutrients, tocopherols and phytochemicals. Current epidemiological evidence has consistently linked increased nut consumption to reduced risk of several chronic conditions including cardiovascular diseases, type 2 diabetes, and inflammation. In contrast, evidence on nut consumption and cancer risk has been insufficient and equivocal. Prostate cancer is the leading cancer among U.S. men, with approximately 220,800 new cases diagnosed in 2015. However, very few studies have investigated the association between nut intake and prostate cancer. Thus, in the current study, we followed 47,299 US men from 1986-2012, and examined (1) whether consuming more nuts prevents getting prostate cancer, and (2) whether consuming more nuts reduces death rates among non-metastatic prostate cancer patients. During 26 years of follow-up, 6,810 men were diagnosed with prostate cancer, and 4,346 of these patients were without metastasis at diagnosis. We found no association between nut intake and being diagnosed with prostate cancer. However, among non-metastatic prostate cancer patients, those who consumed nuts 5 or more times per week after diagnosis had a significant 34% lower rate of overall mortality than those who consumed nuts less than once per month.

MedicalResearch.com Interview with: Dr. Richard Leigh MD Neuro Vascular Brain Imaging Unit National Institute of Neurological Disorders and Stroke National Institutes of Health, Bethesda, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: Patients who suffer an ischemic stroke have limited treatment options. One of the reasons for this is that our treatments can sometimes make the stroke worse by transforming the ischemic stroke into a hemorrhagic stroke. In our study we identified a new piece of information that we can extract from the patient’s MRI scan that informs us on the risk of having a hemorrhage. (more…)
Aging, Author Interviews, Frailty, Genetic Research / 22.06.2016

MedicalResearch.com Interview with: Dr. David Sebastián IRB Barcelona and CIBERDEM researcher MedicalResearch.com: What is the background for this study? What are the main findings? Response: One of the alterations that most affects the quality of life of the elderly is muscle wastage and the resulting loss of strength, a condition known as sarcopenia. At about 55 years old, people begin to lose muscle mass, this loss continues into old age, at which point it becomes critical. However, the underlying causes of sarcopenia are unknown and thus no treatment is available for this condition. Importantly, we have found that the mitochondrial protein Mitofusin 2 is required to preserve healthy muscles in mice. Mitofusin 2 is a mitochondrial protein involved in ensuring the correct function of mitochondria, and it has several activities related to autophagy, a crucial process for the removal of damaged mitochondria. The loss of Mitofusin 2 impedes the correct function of mitochondrial recycling and consequently damaged mitochondria accumulate in muscle cells. (more…)
Author Interviews, Depression, Race/Ethnic Diversity / 22.06.2016

MedicalResearch.com Interview with: Sirry Alang PhD Assistant professor of sociology and anthropology Lehigh University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Discrepancies exist between how some Black populations perceive depression and how depression is conceptualized within research and clinical settings. African Americans are exposed to a lot of stress from structural racism, yet, they perceive themselves to be resilient. The context of stress from discrimination and beliefs about depression inform how they express psychological distress. Depression is thought of as a weakness that is inconsistent with notions of strength in the community. Although depression was expressed through classic depressive symptoms such as feeling hopeless, loss of sleep, and losing interests in activities, symptom like anger, agitation, and the frantic need for human interaction were considered to be indicative of depression. Anger, agitation, and the frantic need for human interaction are not consistent with how depression is defined in the latest manual for psychiatric diagnosis- the DSM-V. (more…)

MedicalResearch.com Interview with: Jonathan Hsu, MD, MAS, FACC, FAHA, FHRS Assistant Professor Cardiac Electrophysiology, Division of Cardiology University of California, San Diego (UCSD) MedicalResearch.com: What is the background for this study? Response: Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide and imparts significant stroke risk. In patients with AF determined to be at intermediate to high risk for thromboembolism, anticoagulation with warfarin (a vitamin K antagonist) or the newer non-vitamin K antagonist oral anticoagulants clearly reduces morbidity and mortality compared to aspirin. We sought to evaluate practice patterns of cardiovascular specialists in the United states to determine how often AF patients at risk for stroke are prescribed aspirin over oral anticoagulation, and predictors of this practice.

MedicalResearch.com Interview with: Dr. Lan Huang PhD Co-founder, Chairman and CEO BeyondSpring Pharmaceuticals, Inc MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study is the toxicity of Docetaxel chemotherapy causes inadequate dosing with Docetaxel due to dose delay, reduction or discontinuation, thus leaving the patient with inadequate chemotherapy treatment. A main finding is a statistically significant p value of 0.002 in lower rates of grade 3 and 4 Neutropenia for patients dosed with a combination of BeyondSpring’s Plinabulin and Docetaxel compared to those patients dosed with Docetaxel alone. As a result, approximately 14 percent more patients stayed on the adequate (dense) dose of Docetaxel in the Docetaxel + Plinabulin arm as compared to Docetaxel alone. (more…)
Author Interviews, Hearing Loss, OBGYNE / 22.06.2016

MedicalResearch.com Interview with: Dr. Álex García-Faura Scientific Director of the Institut Marquès Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our clinical research during the last three years has been focused on the effects of music during the early stages of life; in our preliminary studies, applying music to pregnant patients using abdominal speakers, we discovered that there was no fetal reaction to music and that the fetus would only be able to hear it as a distorted whisper because of the effects of the abdominal wall. We thought that it would be necessary to get the music closer to the fetus, and we decided to try to apply the music vaginally. It was a great decision. (more…)
Author Interviews, Heart Disease, JAMA, Race/Ethnic Diversity, UCSF / 22.06.2016

MedicalResearch.com Interview with: Gregory M Marcus, MD, MAS, FACC, FAHA, FHRS Director of Clinical Research Division of Cardiology Endowed Professor of Atrial Fibrillation Research University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Response: We and others have previously demonstrated that, despite the observation that African Americans on average exhibit more risk factors for atrial fibrillation, they demonstrate a substantially reduced risk of the disease. This suggests that, if we could understand the mechanism underlying this apparent paradox, we might learn something fundamentally important to atrial fibrillation that would be relevant to treating or preventing the disease regardless of race. Building on our previous work demonstrating that, among African Americans, more European ancestry (determined by genomic testing) was a statistically significant predictor of atrial fibrillation, we sought to identify the gene(s) that might underlie this observation. The analysis took two forms. First, we examined if any differences among several well-established single nucleotide polymorphisms (SNP) associated with atrial fibrillation might mediate the race-atrial fibrillation relationship. One such SNP statistically mediated (rs10824026) up to about a third of the race-atrial fibrillation relationship. It’s important to mention that a causal relationship cannot be proven here. Perhaps more remarkable was the observation that the disease-associated alleles of the SNPs most closely associated with atrial fibrillation in multiple studies were actually significantly more common among African Americans, pointing to the complex nature of both the race-atrial fibrillation relationship as well as the genetics of atrial fibrillation. Finally, leveraging the ancestral relationships, we performed a genome wide admixture mapping study with the hope of reducing the penalty for multiple hypothesis testing incurred in conventional genome wide association studies. While several loci revealed associations with atrial fibrillation with small p values, none met our criteria for genome wide significance. (more…)
Author Interviews, Heart Disease, JAMA, Pharmacology, UCLA / 22.06.2016

MedicalResearch.com Interview with: Gregg C. Fonarow, MD, FACC, FAHA Eliot Corday Professor of Cardiovascular Medicine and Science Director, Ahmanson-UCLA Cardiomyopathy Center Co-Chief of Clinical Cardiology, UCLA Division of Cardiology Co-Director, UCLA Preventative Cardiology Program David Geffen School of Medicine at UCLA Los Angeles, CA, 90095-1679 MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Fonarow: Angiotensin receptor neprilysin inhibitors (ARNI) have been demonstrated to reduce mortality in patients with heart failure with reduced ejection fraction. However, to date, the population level impact of optimal implementation of this therapy in the United States has not been evaluated. This new analysis estimates that as many 28,484 deaths in heart failure with reduced ejection fraction patients annually could be prevented or postponed with optimal use of angiotensin receptor neprilysin inhibitors (with sensitivity analyses demonstrating a range of 18,230 to 41,017).

Author Interviews, Heart Disease, Pediatrics, Weight Research / 22.06.2016

MedicalResearch.com Interview with: Annika Rosengren MD Department of Molecular and Clinical Medicine, Institute of Medicine Sahlgrenska Academy University of Gothenburg, Gothenburg, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: In an earlier study we found that while hospitalizations for heart failure decreased among people aged 55 and older in Sweden 1987-2006, there was a clear increase among those younger than 45 years, particularly in young men. We thought that increasing body weight in the population might be a factor behind this. We used anonymized data from more than 1.6 million Swedish men from the Swedish conscript registry aged on average 18 and followed them from adolescence onwards. Those who were overweight as teenagers were markedly more likely to develop heart failure in early middle age. The increased risk of heart failure was found already in men who were within the normal body weight range (a body mass index of 18.5 to 25) in adolescence, with an increased risk starting in those with a BMI of 20 and rising steeply to a nearly ten-fold increased risk in those who were very obese, with a BMI of 35 or over. Among men with a BMI of 20 and over, the risk of heart failure increased by 16% with every BMI unit, after adjustments for factors that could affect the findings, such as age, year of enlistment into the Swedish armed forces, other diseases, parental education, blood pressure, IQ, muscle strength and fitness.

Annals Internal Medicine, Author Interviews, Diabetes, Hepatitis - Liver Disease, Pharmacology / 22.06.2016

MedicalResearch.com Interview with: Kenneth Cusi, M.D., F.A.C.P., F.A.C.E. Professor of Medicine VAMC staff Chief, Division of Endocrinology, Diabetes and Metabolism The University of Florida Gainesville, FL 32610-0226 MedicalResearch.com: What is the background for this study? Dr. Cusi: Many patients with prediabetes or Type 2 Diabetes Mellitus (T2DM) are not diagnosed with Nonalcoholic steatohepatitis (NASH), a disease that is the second cause of liver transplantation in the United States. It is also associated with worse cardiovascular disease and harder to control T2DM. We had done in this population a proof-of-concept study published in Nov 2006 in the NEJM. But we lacked a larger, long-term study for definitive proof. This is the largest SINGLE center study, and the longest ever (3 years). NASH is an overlooked problem for perhaps as many as one-third of patients with Type 2 Diabetes Mellitus. There is now a safe and effective treatment option for patients with T2DM and NASH – pioglitazone will become for NASH what metformin is to the treatment of T2DM: a safe, effective, the “backbone therapy" to which other treatments will be added.

MedicalResearch.com Interview with: Brian W. Haas PhD Department of Psychology Interdisciplinary Neuroscience Graduate Program University of Georgia, Athens, GA MedicalResearch.com: What is the background for this study? Response: A burgeoning body of evidence highlights the role of several key genes within the oxytocin signaling pathway linked to sociability. Although many studies strongly supports the role of OXTR in the phenotypic expression of sociability in humans, the roles of other oxytocin pathway genes, such asOXT, has received relatively little attention.

Author Interviews, Journal Clinical Oncology, Karolinski Institute, Leukemia / 22.06.2016

MedicalResearch.com Interview with: Hannah Bower, MSc Department of Medical Epidemiology and Biostatistics Karolinska Institutet Stockholm, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previously, if left untreated or with symptomatic treatment (up to the 1970’s), the median survival time of patients with chronic myeloid leukemia (CML) ranged between two and three years. Later, interferon alpha and allogeneic stem cell transplantation were introduced. However, improvements in survival were mainly seen in younger patients. Treatment with the tyrosine-kinase inhibitor (TKI) imatinib-mesylate (Glivec®, Gleevec®) began in Sweden in the early 2000 resulting in major survival improvements, with the exception of the old/very elderly. We investigated if these improvements continued to 2013 and if improvements are now observed in the elderly via the life expectancy and the loss in expectation of life; the latter of these quantifies the change in the life expectancy due to a diagnosis of CML. The great improvements in life expectancy, especially in the youngest patients, translate into great reductions in the loss in expectation of life. The major factor contributing to the improvement in the elderly is likely the increasing use of TKIs. (more…)
Author Interviews, Dengue, Infections, Inflammation, Zika / 22.06.2016

MedicalResearch.com Interview with: Clive McKimmie PhD Research Fellow, Virus Host Interaction Team (VHIT), University of Leeds St James’ University Hospital Leeds UK MedicalResearch.com: What is the background for this study? Response: With the rapid spread of Zika in the Americas, attention has been drawn to this group of neglected mosquito-borne viral infections. The Zika virus is not alone in causing problems, others such as dengue and chikungunya viruses are infecting millions of people each year. Yet there’s little doctors can do to help people who get sick. When mosquitoes bite you they can transmit these disease causing viruses. We don’t understand what happens during the early stages of infection very well. However, it is known that the mosquito bite itself somehow helps the virus to infect your body. (more…)
Author Interviews, Cannabis, OBGYNE, Pediatrics / 21.06.2016

MedicalResearch.com Interview with: Dr. Hanan El Marroun, PhD Assistant Professor Department of Child and Adolescent Psychiatry, Department of Epidemiology The Generation R Study Erasmus, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for the study is that little is known about the potential long-term effects of cannabis exposure during pregnancy on child development. The main findings are the prenatal cannabis exposure was associated with differences in cortical thickness in childhood. MedicalResearch.com: What should readers take away from your report? Response: That our findings suggest an association between prenatal cannabis exposure and cortical thickness in children. However, the results must be carefully interpreted, as there may be other factors involved that we did not take into account. Therefore, further research is needed to explore the causal nature of this association. (more…)
