Author Interviews, Circadian Rhythm, Sleep Disorders / 22.12.2016

MedicalResearch.com Interview with: Dr. Nicola Barclay, BA(Hons), MSc, PhD. Lecturer in Sleep Medicine Sleep and Circadian Neuroscience Institute (SCNi) Nuffield Department of Clinical Neurosciences Sir William Dunn School of Pathology University of Oxford MedicalResearch.com: What is the background for this study? Response: We know that extreme sleep deprivation impairs our cognitive functions, particularly attention. This impairment in attention is likely to be driven by physiological mechanisms that change across the waking day (increasing sleep pressure), but also by factors associated with our biological clock. The timing of physiological processes particularly related to attention differ between morning and evening type people (our so called early morning larks and night owls), and so we hypothesised that morning and evening types would differ in their impairments in attention at different times of day, prior to and following 18 hours of sustained wakefulness.

Author Interviews, Genetic Research, Nature, Weight Research / 21.12.2016

MedicalResearch.com Interview with: Prof. Jamal Tazi Institut de Génétique Moléculaire de Montpellier University of Montpellier Montpellier, Cedex, France MedicalResearch.com: What is the background for this study? What are the main findings? Response: Intense drug discovery efforts in the metabolic field highlight the need for novel strategies for the treatment of obesity. In this study we have used a novel approach to uncover novel drugs to treat obesity. Our approach is based on the finding that in humans the energy expenditure balance can be controlled by a single gene LMNA gene that can produce two different proteins with opposing effect on energy expenditure. We identified a molecule ABX300 that targets the expression of LMNA gene and favors energy expenditure leading to fat loss. (more…)

MedicalResearch.com Interview with: Prof. Cathryn Glazener PhD Health Services Research Unit University of Aberdeen Aberdeen,UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prolapse is a condition that affects up to half of all women after childbirth. Women notice a bulge or discomfort in their vaginas due to pressure from the bladder, bowel or womb moving downwards. Women who have surgery for their prolapse have a 3 in 10 chance of needing at least one more operation, so the success rate is not great. Gynaecologists hoped that by reinforcing their repairs the success rate would get better. PROSPECT was a pragmatic, multicentre randomised controlled trial conducted in 35 centres across the UK. Women undergoing their first operation for prolapse were randomised to having a standard repair of the front or back wall of the vagina, or a repair reinforced by synthetic non-absorbable mesh, or a biological graft. We found that, in contrast to previous research, women were just as likely to be cured after standard surgery rather than reinforced repairs. They were just as likely to have other symptoms such as bladder or sexual problems, and other adverse effects such as infection, bleeding or pain. However, about 1 in 10 of the women who had mesh did have mesh exposure when a small portion of the mesh becomes visible through the vaginal wall. Although many women did not have symptoms, about half of those women needed a small operation to remove or bury the exposed mesh. (more…)
Author Interviews, Brain Injury, JAMA, Pediatrics / 21.12.2016

MedicalResearch.com Interview with: Roger Zemek, MD, FRCPC Associate Professor, Dept of Pediatrics and Emergency Medicine, Clinical Research Chair in Pediatric Concussion, University of Ottawa Director, Clinical Research Unit, Children’s Hospital of Eastern Ontario Ottawa, ON MedicalResearch.com: What is the background for this study? Response: While current concussion protocols endorse the conservative view that children should avoid physical activity until completely symptom-free, there is little evidence beyond expert opinion regarding the ideal timing of physical activity re-introduction. In fact, while rest does play a role in concussion recovery, protracted physical rest may actually negatively impact concussion recovery. Further, physiological, psychological, and functional benefits of early physical rehabilitation are observed in other disease processes such as stroke (which is an example of a severe traumatic brain injury). Therefore, our objective was to investigate the relationship between early physical activity (defined within 7 days of the concussion) and the eventual development of persistent post-concussion symptoms at one month.

Author Interviews, JAMA, Pediatrics / 21.12.2016

MedicalResearch.com Interview with: Eyal Cohen, MD, MSc, FRCP(C) Staff Physician, Paediatrics The Hospital for Sick Children Associate Scientist, Research Institute Child Health Evaluative Sciences Associate Professor, University of Toronto   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Major structural or genetic congenital anomalies affect approximately 2 percent to 5 percent of all births in the United States and Europe. Mothers of children born with major congenital anomalies face serious challenges such as high financial pressures, as well as the burden of providing care to a child with complex needs within the home setting, which can impair a mother's health. Little is known about the long-term health consequences for the mother. We assessed whether the birth of an infant with a major congenital anomaly was subsequently associated with an increased risk of death of the infant's mother. The population-based study (n = 455,250 women) used individual-level linked Danish registry data for mothers who gave birth to an infant with a major congenital anomaly between 1979 and 2010, with follow-up until December 31, 2014. A comparison group was constructed by randomly sampling, for each mother with an affected infant, up to 10 mothers matched on maternal age, parity (the number of children a woman has given birth to), and year of infant's birth. Mothers in both groups were an average age of 29 years at delivery. After a median follow-up of 21 years, there were 1,275 deaths (1.60 per 1,000 person-years) among 41,508 mothers of a child with a major congenital anomaly vs 10,112 deaths (1.27 per 1,000 person-years) among 413,742 mothers in the comparison group. Mothers with affected infants were more likely to die of cardiovascular disease, respiratory disease, and other natural causes. (more…)

MedicalResearch.com Interview with: Dr Jamie G Cooper Consultant in Emergency Medicine Aberdeen Royal Infirmary Aberdeen UK MedicalResearch.com: What is the background for this study? Response: Choking in children can be fatal and regularly grapes can be the cause.  We believe that public awareness of the choking hazard posed by grapes (and other similarly shaped foods, such as cherry tomatoes) is not wide spread.  By publishing this article we aimed to highlight the problem to health professionals who look after children and also to the public at large in an attempt to reduce the number of future episodes.

Annals Internal Medicine, Author Interviews, Hematology, Karolinski Institute / 21.12.2016

MedicalResearch.com Interview with: Märit Halmin, MD, PhD student Department of Medical Epidemiology and Biostatistics, Karolinska Institutet,  Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: During recent years the possible negative effects among recipients of stored red blood cells have been investigated.  Despite a large number of studies, including four randomized trials, no consensus exists. We therefore performed the hitherto largest register based cohort study of transfused patients, assessing the association between length of storage of red blood cells and mortality. Our design allowed for detection of small but still clinically significant effect, if such exists. (more…)
Author Interviews, Dermatology / 21.12.2016

MedicalResearch.com Interview with: Mohammed D. Saleem, MD Department of Dermatology Wake Forest School of Medicine Medical Center Boulevard Winston-Salem, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past several years’ numerous research studies have identified comorbidities associated with psoriasis. The media has increasingly become involved with presenting these findings and patients commonly bring these concerns to their physician. The comorbidities are often presented as a relative risk, which can overestimate the effects of exposure, especially when the incidence is quite small. Comorbidities presented as attributed risk or number needed to harm might be a better measure for understanding the association between an exposure and comorbidity. We found that although the relative risk of many diseases associated with psoriasis can be quite large, the attributed risk was small. (more…)
Author Interviews, BMJ, Weight Research / 20.12.2016

MedicalResearch.com Interview with: Igho Onakpoya MD MSc University of Oxford Centre for Evidence-Based Medicine Nuffield Department of Primary Care Health Sciences Oxford UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several medicines used to treat obesity have been withdrawn from the market over the last few years. However, the reasons for, and time trends about their withdrawals have not been systematically researched. We identified 25 anti-obesity medicines withdrawn from the market over the last 50 years. 23 of these analogues of amphetamine or fenfluramine, i.e., neurotransmitters. The reasons for withdrawal in the overwhelming majority of instances were cardiovascular or psychiatric adverse reactions, and drug abuse and dependence. (more…)
Author Interviews, Cancer Research, JNCI / 20.12.2016

MedicalResearch.com Interview with: Theodore Brasky, PhD The Ohio State University Comprehensive Cancer Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a significant amount of data to suggest that long-term, regular use of nonsteroidal anti-inflammatory drugs (NSAIDS; examples include aspirin and ibuprofen) are associated with reduced risks of several cancers. Although the data across studies are inconsistent, one such candidate is endometrial cancer, which is the most common gynecologic cancer. There is good evidence that the use of these medications is associated with improved prognosis among patients diagnosed with colon cancer. Despite the importance of inflammation in endometrial cancer progression, very few have examined whether use of NSAIDs is associated with risk of death or recurrence from the disease. The study we published is the first of its kind to examine NSAID use comprehensively and in a study of over 4,000 patients. (more…)
Author Interviews, Heart Disease, NIH / 20.12.2016

MedicalResearch.com Interview with: Manfred Boehm M.D. Senior Investigator Laboratory of Cardiovascular Regenerative Medicine Center for Molecular Medicine NHLBI-NIH Bethesda, MD 20892 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Common atherosclerosis (hardening of blood vessels) is the leading cause for vascular diseases worldwide. Vascular calcification is a critical component of atherosclerosis and an indicator of negative outcomes. This process is highly regulated and dynamic. However, the underlying mechanism is poorly understood and no direct treatment is available to stop or reverse this devastating buildup of calcium crystals in the vessel wall. Arterial calcification due to deficiency of CD73 is a rare inherited vascular disease characterized by extensive calcification of blood vessels caused by mutation in a gene encoding an enzyme that generates a compound called Adenosine outside of cells. The lack of this important enzyme, CD73, activates a compensatory mechanism to generated Adenosine by an alternative enzyme. Unfortunately, increased activity of this other enzyme is causing accelerated vascular calcification. By using the patient’s own cells, this study characterized the compensatory signaling pathway and discovered several new treatment strategies. (more…)

Author Interviews, Cancer Research, Nature, Wistar / 20.12.2016

MedicalResearch.com Interview with: Cecilia Caino, Ph.D. The Wistar Institute 3601 Spruce Street Philadelphia, PA 19104 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mitochondria have recently experienced a resurgence of interest in the field of cellular biology. Traditionally known for their role in energy production and in programmed cell death, mitochondria are more broadly recognized as signaling hubs and biosynthetic factories. Not surprisingly, mitochondria have been linked to several hallmarks of cancer, including evasion of apoptosis, tissue invasion and metastasis and abnormal metabolic pathways. It has become clear that mitochondria quality control and metabolism-regulated shape changes are dysregulated in cancer. Recent studies identified a novel therapy-resistance mechanism that involves mitochondrial subcellular re-localization and is responsible for enhanced metastatic potential of cancer cells. In this context, the molecular regulators of mitochondrial trafficking in cancer are largely unknown. Through analysis of shRNA screening results, we identified Syntaphilin (SNPH), which is considered to moderate mitochondrial trafficking in neurons, as a non-neuronal tissue specific factor to suppress cancer cell invasion. Using multi-disciplinary cell biological, real time imaging, in vivo studies and human clinical studies, SNPH was revealed to block cell motility and tumor metastasis by regulation of reprogramming of mitochondrial dynamics. We provided evidence from public databases and clinical samples that SNPH levels are decreased in different types of human tumors and low SNPH levels correlate with worse patient prognosis. Overall this study demonstrated a new mechanism by which tumor cell invasion is regulated by a SNPH-mediated pathway. (more…)
Author Interviews, OBGYNE, UCLA, Zika / 20.12.2016

MedicalResearch.com Interview with: Karin Nielsen, MD, MPH Professor of Clinical Pediatrics Division of Pediatric Infectious Diseases David Geffen School of Medicine at UCLA Director, Center for Brazilian Studies MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research was a prospective study in which pregnant women in Rio de Janeiro who developed a rash in the last 5 days between the end of 2015 to mid 2016 were screened for possible infection with Zika virus by a special molecular test (PCR) which looked for the virus in blood or urine. Women who were found to have Zika virus in either blood, urine or both were followed throughout time to look for pregnancy and infant outcomes. We also followed women who had a negative PCR test for Zika as a comparison group. By July 2016, we had outcomes known for 125 Zika affected pregnancies, of these 58 had abnormal outcomes, with 9 fetal losses and 49 babies who had abnormal findings on physical exam or brain imaging, all consistent with neurologic abnormalities. This meant 46% of the pregnant women in our study had an abnormal pregnancy outcome, and 42% of live birth infants were found to have an abnormality in the first few months of life. (more…)

MedicalResearch.com Interview with: Bradley C. Johnston, PhD Prevention Lab, Child Health Evaluative Sciences, The Hospital for Sick Children Research Institute Peter Gilgan Centre for Research and Learning Toronto, Ontario MedicalResearch.com: What is the background for this study? Response: I am scientist at The Hospital for Sick Children and a professor of clinical epidemiology at the University of Toronto and McMaster University in Canada. I have a particular interest in research methodology and preventive medicine. As a research methodologist I am interested in how researchers get to their conclusions. In particular I am interested in the “uncertainty” in estimated treatment or exposure effects. Many guidelines have methodological issues but it was suspected that the nutritional guidelines were especially problematic. Our study in Annals of Internal Medicine set out to document the issues systematically with respect to sugar intake recommendations from authoritative guidelines. (more…)
AHA Journals, Author Interviews, Duke, Social Issues, Stroke / 19.12.2016

MedicalResearch.com Interview with: Matthew E. Dupre, Ph.D. Associate Professor Department of Community and Family Medicine & Duke Clinical Research Institute (DCRI) Duke University MedicalResearch.com: What is the background for this study? What are the main findings? Response: There have been a handful of recent studies showing how divorce and widowhood increase one’s risk of suffering a serious health event such as a heart attack or stroke. Our research is the first to show that an individual’s marital history can have significant consequences for their prognosis after having a stroke. We found that people who never married and those with a history of marital loss were significantly more likely to die after suffering a stroke than those who were stably married. We also found that adults who experienced more than one divorce or widowhood in their lifetime were about 50% more likely to die after having a stroke than those in a long-term stable marriage. We were also somewhat surprised to find that remarriage did not seem to reduce the risks from past marital losses. (more…)

MedicalResearch.com Interview with: Kay Deckers, MSc PhD student School for Mental Health and Neuroscience Department of Psychiatry and Neuropsychology Maastricht University The Netherlands MedicalResearch.com: What is the background for this study? Response: In an earlier review (https://www.ncbi.nlm.nih.gov/pubmed/25504093), we found that renal dysfunction was one the new candidate risk factors of dementia and needed further investigation. MedicalResearch.com: What are the main findings? Response: Albuminuria is associated with an increased risk of developing cognitive impairment or dementia. (more…)
Author Interviews, Biomarkers, Multiple Sclerosis / 19.12.2016

MedicalResearch.com Interview with: Charles Bangham PhD ScD Division of Infectious Diseases, Department of Medicine Imperial College London London, UK MedicalResearch.com: What is the background for this study? Response: Multiple sclerosis (MS) is a neurological disease of the brain and spinal cord, often beginning in the 20s and 30s which can cause both attacks (relapses) and disability over time. Most people with the condition have intermittent episodes of illness at first, but about two-thirds go on to develop a progressive form, known as secondary progressive MS. In this form, there is a gradual loss of nerve cells in the brain, resulting in shrinkage of the brain and progressive disability. Neither the initiating cause of  Multiple sclerosis nor the reasons for this brain shrinkage are known, and existing treatments for the early phase of the condition are unsatisfactory. (more…)
Author Interviews, Brigham & Women's - Harvard, Endocrinology, Infections / 18.12.2016

MedicalResearch.com Interview with: Flaminia Catteruccia PhD Associate Professor of Immunology and Infectious Diseases Department of Immunology and Infectious Diseases Boston, Massachusetts 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mosquito control via lethal insecticides is a key method for reduction of malaria transmission. As insecticide resistance is spreading, new intervention methods are urgent. Our study demonstrates that studies on mosquito biology can provide novel, much needed tools for malaria control. We show how key aspects of mosquito physiology and Plasmodium development can be significantly disrupted in the female Anopheles mosquito by agonists of the insect steroid hormone 20-hydroxyecdysone (20E). Modeling of the data predicts that the integration of 20E agonists in malaria control programs would significantly reduce malaria prevalence to a similar extent as insecticides, but without imposing severe costs to mosquito populations (more…)

MedicalResearch.com Interview with: Heather Hampel, MS, LGC Associate Director, Division of Human Genetics Associate Director, Biospecimen Research Professor, Internal Medicine Licensed Genetic Counselor The Ohio State University Comprehensive Cancer Center Columbus, OH 43221 MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study was part of the Ohio Colorectal Cancer Prevention Initiative, a statewide study being conducted at 50 hospitals that includes universal tumor screening for Lynch syndrome. For the subset of 450 colorectal cancer patients diagnosed under age 50, we performed multi-gene cancer panel testing regardless of the results of their tumor screening for Lynch syndrome since early age of diagnosis is a red flag that a cancer might be hereditary.

Author Interviews, Pediatrics, Pulmonary Disease / 17.12.2016

MedicalResearch.com Interview with: Elizabeth Foglia, MD MSCE Assistant Professor of Pediatrics University of Pennsylvania Perelman School of Medicine Attending Neonatologist Hospital of the University of Pennsylvania The Children's Hospital of Philadelphia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pulse oximetry is a non-invasive method of monitoring oxygen saturation that is frequently used to monitor ill newborns and infants. Previous studies of adults with hypoxemia (low blood oxygen levels) demonstrated that pulse oximetry is less accurate in adults with dark skin, compared to adults with light skin. We sought to determine if skin pigment affects the accuracy of pulse oximetry in infants with hypoxemia. We studied 2 widely used pulse oximeters, and we did not find evidence that skin pigment affects the accuracy of pulse oximetry in infants with hypoxemia. However, the overall performance (combined accuracy and precision) of both oximeters was poor. In addition, one oximeter (the Nellcor Oximax) consistently overestimated the measured blood oxygen level. (more…)
Author Interviews, Brigham & Women's - Harvard, Dental Research, Infections, Rheumatology, Science / 17.12.2016

MedicalResearch.com Interview with: Maximilian F. Konig, MD Division of Rheumatology, Johns Hopkins University School of Medicine Current affiliation: Department of Medicine Massachusetts General Hospital Harvard Medical School MedicalResearch.com: What is the background for this study? Response:The idea that rheumatoid arthritis (RA), an autoimmune disease that leads to chronic joint inflammation and destruction, may be initiated by a bacterial infection is not novel, but has been posited for more than a century. Based on the clinical observation that patients with RA frequently have severe periodontal disease (gum disease), gum inflammation has long been thought to contribute to disease development in RA. However, limited understanding of the mechanisms that fuel and sustain the autoimmune attack in RA made it difficult to pinpoint a specific bacterial trigger. In recent years, our understanding of the abnormal immune response that attacks the joints in patients with RA has grown exponentially, and we now know that disease-specific autoantibodies (ACPAs) target modified self-proteins (this modification is known as citrullination). It is this abnormal immune response against citrullinated proteins that appears to drive the joint (and sometimes lung) inflammation seen in rheumatoid arthritis. Recent studies from our laboratory at The Johns Hopkins University (led by principle investigator Felipe Andrade, MD, PhD) suggested that an immune cell called the neutrophil, which normally protects us from infection at sites like the oral cavity or anywhere else in the body, also appears to be the source of the proteins attacked in RA. We were therefore interested to understand what drives the association of gum disease, an inflammation commonly triggered by bacteria, with RA. (more…)
Author Interviews, Heart Disease, JACC, Surgical Research / 17.12.2016

MedicalResearch.com Interview with: Frederick L. Grover, M. D. Professor, Division of Cardiothoracic Surgery Past Chair, Department of Surgery University of Colorado School of Medicine-Anschutz Medical Campus Aurora, CO Past President, Society of Thoracic Surgeons Vice Chair, Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry MedicalResearch.com: What is the background for this study? What are the main findings? Response: Following approval of the first transcatheter aortic heart valve late in 2011 the TVT-R was established and data entry was mandated by CMS for all patients who were undergoing transcatheter valve therapy.  Data is currently collected on transcatheter aortic valves (TAVR) from two companies, transcatheter mitral clip procedures (TMC), transcatheter mitral valve in valve or valve in ring procedures and aortic valve in valve procedures.  A report is published annually jointly in the Journal of the American College of Cardiology (JACC) and the Annals of Thoracic Surgery (ATS).  This report contains data from the beginning of 2012 through December 31, 2015.  Peoperative risk factors, operative details and outcomes data are collected prior to procedures, during the hospitalization, 30 days post procedure and at one year and later data can be collected by linking to CMS administrative data. For this annual report we concentrated on touching on some of the highlights since the length of the manuscript is limited. We discussed the trends in TAVR, since this is the most common procedure performed, the last two years’ experience in mitral clips since a very detailed paper was published on this last year, and the mitral valve in valve and ring since the results for this procedure were impressively good. In regard to TAVR, 418 sites perform this procedure and the number of cases in 2015 increased from 16,295 in 2014 to 24,808.  Very importantly, mortality and complications have been decreasing each year, probably related to improvements in the technology with smaller catheter and sheath sizes leading to less vascular complications, greater experience of those doing the procedures, a less sick group of patients going initially from those too ill to do an open operation on, to very high risk to high risk according to approval criteria.    The age of the patients however is most often in the 80s.

Author Interviews, MRI, OBGYNE, Pediatrics / 17.12.2016

MedicalResearch.com Interview with: Prof Paul D Griffiths, FRCR and Cara Mooney, Study Manager: MERIDIAN Clinical Trials Research Unit The University of Sheffield  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Around three in every 1000 pregnancies is complicated by a fetal abnormality. In the UK Ultrasonography (USS) has, for many years, been the mainstay of antenatal screening and detailed anomaly scanning to detect such abnormalities.  However previous studies have suggested that in utero Magnetic Resonance (iuMR) imaging may be a useful adjunct to USS for detecting these brain abnormalities in the developing fetus. This study was designed to test the diagnostic accuracy and clinical impact of introducing fetal MR in to the diagnostic pathway. Our results show that iuMR has an overall diagnostic accuracy of 93% compared to ultrasound at 68%, this is an increase in diagnostic accuracy of 25%. When divided into gestational age group the improvement in diagnostic accuracy ranged from 23% in the 18-23 week group, and 29% in the 24 week and over group. IuMR provided additional diagnostic information in 49% of cases, changed prognostic information in at least 20% and the contribution to clinical management was felt to be at least ‘significant’ in 35% of cases. IuMR also had high patient acceptability with at least 95% of women stating that they would have an iuMR if a future pregnancy were complicated by a fetal brain abnormality. (more…)
Author Interviews, Outcomes & Safety / 17.12.2016

MedicalResearch.com Interview with: Michelle P. Salyers Ph.D. Professor, Psychology Director, Clinical Psychology Program Director, ACT Center of Indiana Affiliated Scientist, Regenstrief Institute, Inc. Indiana University-Purdue University Indianapolis, IN MedicalResearch.com: What is the background for this study? What are the main findings? Response: Professional burnout among healthcare providers is receiving more attention in research and in public press. There have long been speculations that the level of burnout may be related to quality of care provided, and many studies have been done linking provider burnout with different aspects of quality of care. This study brings together that literature, to summarize and quantify the link between professional burnout in healthcare provider and the quality of care they provide. We were able to combine data from 82 independent samples, across health care disciplines, settings, and types of quality indicators. We found small to medium relationships between provider burnout and indicators of quality of care. (more…)
Author Interviews, Education / 17.12.2016

MedicalResearch.com Interview with: Pallavi Amitava Banerjee, PhD Lecturer, Graduate School of Education University of Exeter, UK MedicalResearch.com: What is the background for this study? Response: Science technology engineering mathematics skills are highly valued in the UK as in most other developed countries of the world. Concerns were raised in the past by the Royal Society, Science Council and other learned societies and the UK Parliament about the insufficient number of young people wanting to take up these subjects beyond school. What then followed were a range of STEM enrichment and enhancement activities delivered at the local and national level. These activities were run to help young people appreciate science and math better to break the myth that these are only for the brainy. Students from secondary schools did hands-on practical activities, had STEM ambassador visits and several other events organized. (more…)
Author Interviews, Hematology / 16.12.2016

MedicalResearch.com Interview with: Jerry Powell MD Medical Director North America Commercial Operations CSL Behring MedicalResearch.com: What is the background for this study? Response: The new IDELVION results presented at the American Society of Hematology (ASH) are from a pooled analysis of clinical studies from the global PROLONG-9FP clinical development program. The analysis assessed the relationship between estimated factor IX activity levels and clinical bleeding risk in adult hemophilia B patients treated with IDELVION using prophylaxis or on-demand (episodic) treatment. The PROLONG-9FP clinical development program included five Phase I through Phase III open-label, multicenter studies evaluating the pharmacokinetics, safety and efficacy of IDELVION in children and adults with hemophilia B.

MedicalResearch.com Interview with: Dr. Kevin Campbell MD FACC Wake Heart and Vascular Assistant Professor of Medicine,  UNC School of Medicine Cardiology and Cardiac Electrophysiology in Raleigh, Smithfield and Wilson North Carolina  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this study, data was analyzed from nearly 1800 patients who had ST elevation MI.  Findings were published in Heart.  They found that younger  smokers (age under the age of 50)  had an 8-fold increased risk of acute STEMI , when compared to ex- and never smokers. In addition, researchers found that current smokers of all ages were 3.26 times more likely to have STEMI than ex- and never-smokers—suggesting that if you stop smoking, you can reduce your risk for heart attack.

Aging, Author Interviews / 16.12.2016

MedicalResearch.com Interview with: Juan Carlos Izpisua Belmonte PhD Professor, Roger Guillemin Chair Salk Institute of Biological Science's Gene Expression Laboratory MedicalResearch.com: What is the background for this study? Response: Previous studies from different laboratories including ours demonstrated that cellular reprogramming to pluripotency has the capacity to rejuvenate old cells in culture (in a dish) to a younger state. In 2011, we published a study in Nature demonstrating that cellular reprogramming could rejuvenate cells from patients suffering from Hutchinson–Gilford progeria syndrome (HGPS), a premature aging syndrome. The current study started after this publication back in 2012 and the two major questions that we had were: -Could partial, but not complete, cellular reprogramming rejuvenate cells? -Could partial reprogramming rejuvenated cells in a living organism improving its health and lifespan?

Abuse and Neglect, Author Interviews, Pediatrics, University of Pennsylvania / 16.12.2016

MedicalResearch.com Interview with: Joanne N. Wood, MD, MSHP Assistant Professor of Pediatrics Perelman School of Medicine at the University of Pennsylvania Research Director, SafePlace Faculty, PolicyLab The Children’s Hospital of Philadelphia  MedicalResearch.com: What is the background for this study? Response: Each year the U.S. Army Family Advocacy program (FAP) investigates between 6000 to 9000 reports of alleged abuse or neglect involving children of Army service members.   In approximately 48% of reported cases FAP determines a child was a victim of maltreatment, substantiates the report, and collaborates with local civilian child protection service (CPS) agencies in providing services and ensuring safety. Thus, FAP plays a key role in supporting Army families and protecting children.  But FAP can only investigate and respond to cases of child abuse and neglect about which they are aware. (more…)
