AHA Journals, Author Interviews, Brigham & Women's - Harvard, Endocrinology, Heart Disease, Thyroid Disease / 17.09.2016

MedicalResearch.com Interview with: Layal Chaker, MD, MSc PhD candidate Department of Endocrinology and Epidemiology Erasmus Medical Center Rotterdam, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: The association of thyroid function with coronary heart disease is well–established but not much was known about the association of thyroid function with sudden cardiac death. We conducted the study with the hypothesis that thyroid hormone levels affect cardiovascular risk factors and therefore could also affect the risk of sudden cardiac death (SCD). We were surprised to see that when we control our analyses for these cardiovascular risk factors, the association of high and high-normal thyroid function with SCD remained similar, suggesting that other pathways could play a role. Thyroid hormone has different effects on the cardiovascular systems and future studies should identify which pathway could be responsible for the increased risk of sudden cardiac death with higher thyroid hormone levels. This could lead to better assessment of individual risk and identify possible prevention targets. (more…)
Author Interviews, Brigham & Women's - Harvard, Infections, JAMA, Ophthalmology / 17.09.2016

MedicalResearch.com Interview with: Dr. Daria Van Tyne, PhD The Gilmore Lab Department of Ophthalmology Harvard Medical School Massachusetts Eye and Ear Infirmary Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: A specific clone of E. coli, type ST131, which produces an extended-spectrum beta-lactamase (ESBL – an enzyme that inactivates many penicillin-type antibiotics), has rapidly spread around the globe to become the leading cause of multidrug-resistant, non-intestinal E. coli infection. Despite this, E. coli is a rare cause of infection of the cornea. A patient was recently seen at the Massachusetts Eye and Ear Infirmary with a severe E. coli infection of the cornea, and the large number of antibiotic resistances of this strain tipped us off to the possibility that it might be the highly virulent ST131 ESBL type. By sequencing the DNA of its genome, we found that it was indeed ST131 ESBL E. coli. Moreover, we discovered a new mutation in this strain that allows it to produce a slimy outer coating on its surface. This slime layer, or capsule, makes the bacteria more resistant to removal by phagocytic cells of the immune system. The slime layer also makes these particular colonies appear different on a special type of agar that contains the dye Congo Red. (more…)
Accidents & Violence, Author Interviews, Cannabis, Columbia, Opiods / 17.09.2016

MedicalResearch.com Interview with: June H. Kim Doctoral candidate,Department of Epidemiology Mailman School Public Health Columbia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: A previous study indicated that states with medical marijuana laws had a reduced rate of opioid overdoses. If this is true, we'd expect to see similar reductions in opioid use associated with these laws. For this study, we used data from the FARS, a national surveillance system that records any crash events on US public roads that result in a fatality. Some states provide uniform testing of the majority of their deceased drivers, year to year. Among these states, we found that there was a lower prevalence of positive opioid toxicology tests among drivers crashing in states with an operational medical marijuana versus drivers crashing in states before a future medical marijuana law is implemented, particularly among drivers aged 21-40.

Author Interviews, Pediatrics, Social Issues, Toxin Research / 17.09.2016

MedicalResearch.com Interview with: Dr. Katherine Ahrens PhD Office of Population Affairs Rockville, MD 20852 MedicalResearch.com: What is the background for this study? Response: Lead exposure among children is linked to many adverse effects on health and cognitive development, which can be irreversible. The National Center for Health Statistics (NCHS) has linked 1999 to 2012 National Health and Nutrition Examination Survey (NHANES) data to administrative data for the Department of Housing and Urban Development’s (HUD) largest rental assistance programs (1999 through 2014), and these linked data allow calculation of the first-ever national blood lead level estimates among children living in HUD-assisted housing. Here we compare blood lead levels among children 1 to 5 years of age in 2005 to 2012 who received housing assistance during 1999 to 2014 with levels among children who did not receive housing assistance during that period.

Author Interviews, Cost of Health Care, OBGYNE, Outcomes & Safety, University Texas / 17.09.2016

MedicalResearch.com Interview with: Fangjian Guo, MD, PhD Assistant Professor BIRCWH Scholar Department of Obstetrics & Gynecology Center for Interdisciplinary Research in Women’s Health The University of Texas Medical Branch MedicalResearch.com: What is the background for this study? What are the main findings? Response: National guidelines consistently recommend against cervical cancer screening among women with a history of a total hysterectomy for a benign condition. These women are unlikely to develop high-grade cervical lesions. The goal of our study was to assess whether these guidelines are being followed. We examined the use of Pap testing among US adult women with a history of total hysterectomy for a benign condition and the roles of health care providers and patients in the initiation of Pap test use. We found that in 2013, 32% of women who have had a hysterectomy received an unnecessary recommendation for cervical cancer screening from a health care provider in the past year; 22.1% of women with hysterectomy received unnecessary Pap testing. Although the majority of Pap tests were performed at a clinician’s recommendation, approximately one fourth were initiated by patients without clinician recommendations. According to standard 2010 US Census population figures, about 4.9 million unnecessary Pap tests are performed annually among women who have had a total hysterectomy for a benign condition. At approximately $30 per test, $150 million in direct medical costs could be saved annually if screening guidelines were followed for these women. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Heart Disease / 17.09.2016

MedicalResearch.com Interview with: Holly Mattix-Kramer, MD, MPH Public Health Sciences Medicine, Nephrology Associate Professor Loyola Medicine, Illinois MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background is that the Systolic Blood Pressure Lowering Intervention Trial (SPRINT) showed that intensive systolic blood pressure lowering reduces all-cause mortality by 27% compared to standard blood pressure lowering among adults age 50 years and older without diabetes or stroke but with high cardiovascular disease risk. We applied these findings to the U.S. population and asked "What if intensive systolic blood pressure lowering were applied to the U.S. population who meet SPRINT eligibility criteria? We found that approximately 18.1 million U.S. adults meet SPRINT criteria and that their annual mortality rate is 2.2%. If intensive systolic blood pressure lowering reduces all-cause mortality by 27%, then the annual mortality rate would be reduced to 1.6% and approximately 107,500 deaths would be prevented each year.

Addiction, Alcohol, Author Interviews, Psychological Science / 16.09.2016

MedicalResearch.com Interview with: Kristina J. Berglund Department of Psychology University of Gothenburg MedicalResearch.com: What is the background for this study? What are the main findings? Response: In Sweden, care providers do offer different treatment strategies for individuals who have alcohol problems, where some offer a treatment where the goal is abstinence and other offer a treatment where the goal is low-risk consumption. We wanted to investigate how important it was for having a successful treatment when there was congruence between the patient’s goals and the advocated goal of the treatment, and when there was not. The main findings was that that if the patient had a goal of abstinence than it was much more likely to reach that goal if the patient went to a treatment that advocated abstinence. It was less likely to reach the goal if a patient had a goal of low-risk consumption and went to a treatment that advocated low-risk consumption. The treatment that advocated abstinence was also more effective when the patient were ambivalent of his/her own goal. (more…)
Author Interviews, Diabetes, Social Issues, Weight Research / 16.09.2016

MedicalResearch.com Interview with: Professor Timothy Frayling PhD Professor of Human Genetics University of Exeter Medical School Exeter, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that genes and environmental factors influence our Body mass index. We know less about if and how they interact. We wanted to answer the question of whether or not aspects of the environment and our lifestyles accentuate any genetic predisposition to obesity. The question is important as it may highlight aspects of the environment that cause some people to be particularly susceptible to gaining weight. Previous, separate, studies have suggested that specific aspects of the environment are to blame. These included sugary drinks, fried food and TV watching. (more…)
Author Interviews, Diabetes, Vitamin D / 16.09.2016

MedicalResearch.com Interview with: Dr. Elisa Benetti PhD Department of Drug Science and Technology University of Turin Turin, Italy MedicalResearch.com: What is the background for this study? Response: The idea for this study comes from the debate on the role of vitamin D supplementation in the prevention or progression of type 2 diabetes (T2DM). Epidemiological data point at a strong association between vitamin D deficiency and T2DM prevalence, however a causal relationship is still lacking. Here we wanted to explore the effect of vitamin D administration on insulin-sensitivity, particularly focusing on skeletal muscle, which is a crucial tissue in the maintenance of glucose homeostasis and which was suggested to be a tissue target of vitamin D. Using a murine model of insulin-resistance induced by a High Fat-High Sugar Diet (HFHS), we demonstrated that a vitamin D supplementation (7 μg•kg-1, i.p. three times/week) was able to revert the deleterious effects evoked by the diet, including the increase in body weight and in the HOMA-IR (a parameter of insulin resistance) and the glucose tolerance impairment. Consistently, at the muscle level, vitamin D increased the insulin sensitivity by reducing tissue inflammation and fat accumulation (myosteatosis). These effects are due, at least in part, to the inhibition exerted by vitamin D on carboxymethyl-lysine (CML) production, one of the main Advanced Glucose End-products (AGEs), and on its receptor RAGE. Collectively, our data indicate the ability of vitamin D to reduce the development of muscle insulin resistance, the primary defect in T2DM patients. (more…)
Author Interviews, Depression, Diabetes / 16.09.2016

MedicalResearch.com Interview with: Dr Cathy E. Lloyd Professor of Health Studies School of Health, Wellbeing and Social Care Faculty of Wellbeing, Education and Language Studies The Open University Milton Keynes UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know from earlier epidemiological research that people with diabetes have an increased risk of developing depression and other mental health problems compared to those without diabetes. However the impact of this and what treatment and care should be provided is still unclear, in particular in countries other than the US or the UK. Our study aims to redress that imbalance, collecting data on diabetes and depression in 16 countries across the globe. Ours is the first study to measure depressive symptoms but also use a standardised clinical interview to diagnose depression according to ICD criteria. Overall 10.6% received a diagnosis of Major Depressive Disorder (MDD), however prevalence rates differed widely between countries with 1% diagnosed with MDD in Uganda and nearly 30% in Bangladesh. Twenty-five percent reported subthreshold levels (PHQ-9 score 5 -9) of depression. Those with MDD were significantly more likely to be female and living in an urban rather than rural location (p<0.001). Age and duration of diabetes did not significantly differ between those with and without MDD. Multi-variable analyses demonstrated that while controlling for country, a diagnosis of MDD was significantly associated with female sex, lower education, taking insulin, less exercise, higher levels of diabetes-related distress and a previous diagnosis of MDD. A negligible proportion of those with either MDD or subthreshold levels of depression had a diagnosis or any treatment for their depression recorded in their medical records. (more…)
Author Interviews, Blood Pressure - Hypertension, JAMA, Stanford / 16.09.2016

MedicalResearch.com Interview with: Ilana B. Richman, MD Palo Alto VA Health Care System, Palo Alto, California Center for Primary Care and Outcomes Research/Center for Health Policy Department of Medicine Stanford University School of Medicine Stanford, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: In November of 2015, researchers published results from the Systolic Blood Pressure Intervention Trial (SPRINT). This large, NIH-funded study compared a systolic blood pressure target of 120 mm Hg vs 140 mm Hg among hypertensive, nondiabetic patients at elevated risk for cardiovascular disease. SPRINT reported a 25% reduction in the rate of cardiovascular disease and death among those treated to a lower target. Those treated to a lower target blood pressure, though, experienced certain adverse events more frequently. Our cost effectiveness analysis asked two questions: given the potential risks and benefits described in SPRINT, does achieving a lower systolic blood pressure result in net benefit over the course of a lifetime? And if it does, how much would it cost, compared to standard treatment? We found that achieving a lower blood pressure target does result in a net benefit, with a gain of about 0.9 years of life (quality adjusted) among those treated to a lower target compared to those treated to a standard target. This gain, though, required some investment. We found that treating to a lower blood pressure target cost $23,777 per quality-adjusted life year gained. Compared to other commonly used interventions here in the US, this would be considered an excellent value. (more…)
Author Interviews, OBGYNE, Pediatrics, PLoS / 16.09.2016

MedicalResearch.com Interview with: Joseph Leigh Simpson, MD FACOG, FACMG President at International Federation of Fertility Societies March of Dimes Foundation White Plains, NY MedicalResearch.com: What is the background for this study? Response: Preterm birth (PTB) is the most common single cause of perinatal and infant mortality, affecting 15 million infants worldwide each year with global rates increasing. A total of 1.1 million infants die each year. Preterm births and their complications are the leading cause of deaths in children under age 5. The biological basis of preterm birth remains poorly understood, and for that reason, preventive interventions are often empiric and have only limited benefit. Large differences exist in preterm birth rates across high income countries: 5.5 percent in Sweden and at present 9.6 percent in the U.S. The International Federation of Gynecologists and Obstetricians (FIGO)/March of Dimes Working Group on Preterm Birth Prevention hypothesized that identifying the risk factors underlying these wide variations could lead to interventions that reduce preterm birth in countries having high rates.

Author Interviews, Diabetes / 16.09.2016

MedicalResearch.com Interview with: Dr. Samiul Mostafa Honorary Clinical Lecturer Diabetes Trials Unit University of Oxford MedicalResearch.com: What is the background for this study? Response: In managing people with Type 2 diabetes mellitus (T2DM), international guidelines recommend individualisation of HbA1c (glucose) targets for long term maintenance; however, few data are available on the potential benefits that different blood sugar control targets might achieve. Therefore, there is a need to learn more about the incremental benefits of progressively lowering blood sugar levels. In this computer modelling study, we used the UKPDS Outcomes Model version 2.0 to estimate 10-year event rates for myocardial infarction (MI, heart attack), stroke, blindness and amputation by entering baseline risk factor variables (for example, weight, height, LDL-cholesterol, systolic blood pressure) taken from a for a current population of 5766 people with T2DM. Complication rates were estimated with HbA1c levels held constant at 10%, 9%, 8%, 7% and 6% for each individual whilst maintaining their risk factors at their baseline values. Standard statistical methods were used to calculate relative risk reductions of complications at each HbA1c level. (more…)
Author Interviews, HIV, Infections, STD / 16.09.2016

MedicalResearch.com Interview with: Noah Kojima David Geffen School of Medicine University of California Los Angeles, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: One of the most exciting new methods to prevent human immunodeficiency virus (HIV) type 1 infection is through the use of chemical pre-exposure prophylaxis (PrEP), which has been shown to be safe and effective in randomized-controlled trials and “real world” studies among men who have sex with men (MSM). However, reports of high incidence of sexually transmitted infections (STIs) and condomless sex in PrEP trials has led clinicians and public health advocates to be concerned that the use of PrEP for HIV might lead to higher STI incidence due to increased sexual risk behavior. We found that PrEP for HIV infection is associated with increased risk of STI acquisition among MSM in a meta-analysis of prior studies. (more…)

Author Interviews, Gender Differences, Heart Disease, JAMA, Menopause / 15.09.2016

MedicalResearch.com Interview with: Taulant Muka, MD, MPH, PhD Postdoctoral Researcher Erasmus University, Rotterdam MedicalResearch.com: What is the background for this study? What are the main findings? Response: Menopause marks a major life transition for women, resulting in the loss of ovarian follicle development. Although menopause is a universal phenomenon among women, the timing of the final menstrual period differ greatly between women, and is considered a marker of aging. By quantifying data of nearly 310,329 non-overlapping women, we found that women who experienced an early menopause (i.e. younger than 45 years) have an excess risk of CHD, CVD-mortality and all-cause mortality. Furthermore, being 45-49 years at menopause compared to ≥50 years was associated with increased risk of carotid atherosclerosis. (more…)
Author Interviews, Breast Cancer, JAMA / 15.09.2016

MedicalResearch.com Interview with: Tehillah S. Menes, MD Department of Surgery Tel Aviv-Sourasky Medical Center Tel Aviv, Israel MedicalResearch.com: What is the background for this study? Response: Atypical ductal hyperplasia (ADH) is a known risk factor for breast cancer. The diagnosis is made by a biopsy showing a uniform proliferation of cells lining the ducts of the breast. These cells have monomorphic round nuclei and characteristically fill only part of the involved duct. Women diagnosed with ADH are recommended to undergo increased surveillance and offered chemoprevention (i.e. Tamoxifen) for risk reduction. Most studies reporting on the risk of subsequent breast cancer in women with ADH were done prior to the wide use of screening mammography and percutaneous needle biopsy. Our study examined 10-year risk of invasive breast cancer in women diagnosed with ADH (by needle biopsy or excisional biopsy), using data collected by the Breast Cancer Surveillance Consortium (BCSC).

Author Interviews, Education / 15.09.2016

MedicalResearch.com Interview with: Mr. Alexander Burgoyne Department of Psychology Michigan State University East Lansing, MI MedicalResearch.com: What is the background for this study? What are the main findings? Response: Within the field of psychology, the question of whether intelligence has a role in chess expertise has been debated since at least 1927 with the publication of "Psychologie des schachspiels" by Djakow, Petrowski, and Rudik. More recently, the titles of popular press books such as Talent is Overrated speak to the belief that individual differences in abilities, such as intelligence, do not matter, or can be circumvented by training. We analyzed a half-century worth of research on intelligence and chess skill and found that cognitive ability contributes meaningfully to individual differences in chess skill, particularly in younger and/or less skill players.

Author Interviews, Duke, Medical Imaging, MRI, PLoS, Psychological Science, Social Issues / 15.09.2016

MedicalResearch.com Interview with: Kevin S. LaBar, Ph.D. Professor and Head, Cognition & Cognitive Neuroscience Program Co-Director of Undergraduate Studies in Neuroscience Center for Cognitive Neuroscience Duke University Durham, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Emotion research is limited by a lack of objective markers of emotional states. Most human research relies on self-report, but individuals may not have good insight into their own emotions. We have developed a new way to identify emotional states using brain imaging and machine learning tools. First, we induced emotional states using film and music clips while individuals were in an MRI scanner. We trained a computer algorithm to identify the brain areas that distinguished 7 emotions from each other (fear, anger, surprise, sadness, amusement, contentment, and a neutral state). This procedure created a brain map for each of the 7 emotions. Then, a new group of participants self-reported their emotional state every 30 seconds in an MRI scanner while no stimuli were presented. We could predict which emotion was spontaneously reported by the subjects by comparing their brain scans to each of the 7 emotion maps. Finally, in a large group of 499 subjects, we found that the presence of the fear map during rest predicted state and trait anxiety while the presence of the sadness map predicted state and trait depression.

MedicalResearch.com Interview with: Eva Gonzalez Suarez, PhD Group Leader Transformation and Metastasis lab. Cancer Epigenetics and Biology Program-PEBC Institut d'Investigació Biomédica de Bellvitge-IDIBELL Hospital Duran i Reynals Avinguda Gran Via de l'Hospitalet, L'Hospitalet de Llobregat-Barcelona-Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Thousands of cancer patients worldwide are taking RANKL inhibitors for the management of bone metastasis, based on the key role of RANKL and its receptor, RANK, driving osteoclastogenesis. RANK signaling pathway acts as a paracrine mediator of progesterone in mouse and human mammary epithelium. RANK expression is associated with poor prognosis in breast cancer even though its therapeutic potential remained unknown. Complementary genetic and pharmacological approaches demonstrate that therapeutic inhibition of RANK signaling drastically reduces the cancer stem cell pool, decreases tumor and metastasis initiation and enhances sensitivity to chemotherapy in mouse models that closely resemble the clinical disease. Mechanistically, genome wide expression analyses showed that anti-RANKL therapy promotes differentiation of tumor cells into milk-producing cells, as observed during pregnancy. (more…)
Author Interviews, NEJM, Prostate Cancer / 15.09.2016

MedicalResearch.com Interview with: Professor Jenny Donovan  PhD OBE FMedSci NIHR-SI AcSS FFPHM Director, NIHR CLAHRC West (National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care West) at University Hospitals Bristol NHS Trust Bristol, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: PSA testing identifies many men with prostate cancer, but they do not all benefit from treatment. Surgery, radiation therapy and various programs of active monitoring/surveillance can be given as treatments for fit men with clinically localized prostate cancer. Previous studies have not compared the most commonly used treatments in terms of mortality, disease progression and patient-reported outcomes. In the ProtecT study, we used a comprehensive set of validated measures, completed by the men at baseline (before diagnosis), at six and 12 months and then annually for six years. The main finding is that each treatment has a particular pattern of side-effects and recovery which needs to be balanced against the findings from the paper reporting the clinical outcomes (Hamdy et al).

MedicalResearch.com Interview with: Muyibat Adelani, MD Assistant Professor of Orthopaedic Surgery Washington University St. Louis MedicalResearch.com: What is the background for this study? What are the main findings? Response: In our practice, we noticed that more patients are coming in already having had MRIs. We wanted to know how many people actually had weight-bearing knee x-rays before the MRI. We found that only a quarter of patients had weight-bearing x-rays before the MRI. We found that half of the MRIs obtained prior to referral to an orthopaedic surgeon did not contribute to the patient's treatment. (more…)

MedicalResearch.com Interview with: Mr Liam Satchell Research Associate Department of Psychology University of Portsmouth, UK MedicalResearch.com: What is the background for this study? Response: Most people in general are really interested in trying to understand "body language", how a person behaves may give clues to their psychology. However, psychology has rarely engaged in an empirical investigation of what information about personality may be available in largely automatic movements, such as walking. We brought together techniques from psychology research and sports and exercise science to investigate what features of personality may be available in gait. (more…)

MedicalResearch.com Interview with: Gillian D. Sanders-Schmidler Ph.D. Professor of Medicine Duke Evidence Synthesis Group, Director Duke Evidence-based Practice Center, Director Duke Clinical Research Institute Duke University MedicalResearch.com: What is the background for this study? Response: In 1996, the original panel on cost effectiveness in health and medicine published recommendations for the use of cost effectiveness analysis. During the 20 years since the original panel’s report, the field of cost-effectiveness analysis has advanced in important ways and the need to deliver health care efficiently has only grown. In 2012 the Second Panel on Cost Effectiveness in health and Medicine was formed with a goal of reviewing and updating the recommendations. This paper summarizes those recommendations. This process provided an opportunity for the Panel to reflect on the evolution of cost-effectiveness analysis and to provide guidance for the next generation of practitioners and consumers. (more…)

MedicalResearch.com Interview with: Larissa A. Meyer, MD MPH F.A.C.O.G. Assistant Professor Dept of Gynecologic Oncology and Reproductive Medicine Houston, TX 77030-1362 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the completion of two randomized controlled trials, controversy regarding the optimal approach for the treatment of advanced ovarian cancer remains. Our observational study highlights the importance of thoughtful selection of individuals for primary cytoreductive surgery for advanced ovarian cancer. Our results suggest that primary cytoreductive surgery may improve survival for patients with stage IIIC ovarian cancer who are likely to achieve an optimal cytoreduction, while neoadjuvant chemotherapy may be the preferred option for many women with stage IV ovarian cancer.

MedicalResearch.com Interview with: Johanna M. Uitti, MD Department of Paediatrics and Adolescent Medicine Turku University Hospital Turku, Finland MedicalResearch.com: What is the background for this study? What are the main findings? Response: According to several national guidelines, close follow-up is required if initial observation without antimicrobial agents is chosen for the management of acute otitis media (AOM) in children. The aim of this study was to examine whether close follow-up with reexamination is needed for children with AOM initially managed without antimicrobial agents who have symptomatic improvement during the first week after diagnosis, as assessed by their parents. Of the 104 children with symptomatic improvement, 3 (2.9%) developed worse signs or perforation of the tympanic membrane as seen on otoscopy. In contrast, of the 54 children with symptomatic failure, 16 (29.6%) developed worse signs or perforation of the tympanic membrane as seen on otoscopy. (more…)

MedicalResearch.com Interview with: Josep Rodés-Cabau, MD Director, Catheterization and Interventional Laboratories Quebec Heart and Lung Institute Professor, Faculty of Medicine, Laval University Quebec City, Quebec, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: Infectious endocarditis (IE) is one of the most serious complications after surgical prosthetic valve replacement. There are however scarce data regarding the incidence, predictive factors, treatment, and outcomes of IE post-TAVR. To date, the present study represents the largest series of IE post-TAVR, and the main findings can be summarized as follows: (1) the incidence of infective endocarditis (IE) post-TAVR is similar to that reported for IE after surgical prosthetic valve replacement; (2) among patients undergoing TAVR, younger age, male sex, a history of diabetes mellitus, and moderate-to-severe residual aortic regurgitation were associated with a higher risk of IE, (3) Enterococci species was the most frequently isolated pathogen, (4) IE post-TAVR was associated with a very high rate of in-hospital complications and mortality during index hospitalization and at follow-up.

MedicalResearch.com Interview with: Pooja Rao, MD, MSCE Assistant Professor Division of Pediatric Hematology/Oncology Milton S. Hershey Medical Center Penn State College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although many chemotherapy drugs can cause birth defects, no standardized guidelines exist for pregnancy screening in adolescent female patients with cancer. Additionally, little is known about how often they are screened prior to receiving treatment. Our study found that adolescent girls are not adequately screened for pregnancy prior to receiving chemotherapy or CT scans that could potentially harm a developing fetus. Adolescents with acute lymphoblastic leukemia, the most common childhood cancer, had the lowest pregnancy screening rates of the patients studied. (more…)

MedicalResearch.com Interview with: Prof. Xavier Jouven Service de Cardiologie Hôpital Européen Georges Pompidou Paris MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are many cardiac arrests (around 300 000 per year in United States). The possibility to collect organs from a certain proportion of those cardiac arrests represents an important opportunity to fill the gap of the organ shortage. It is absolutely mandatory to identify patients with no chance of survival. This study showed 3 criteria which allow this early identification. Several thousands of patients die every year waiting for organ transplantation. (more…)
