Author Interviews, Infections, NIH, Rheumatology / 31.03.2014

MedicalResearch.com Interview with: Eleftherios Mylonakis, M.D., Ph.D., FIDSA Dean's Professor of Medical Science Chief, Infectious Diseases Division Alpert Medical School and Brown University and Dr. Irene Kourbeti MD Research Associate Infectious Disease Division Rhode Island Hospital, Providence, RI MedicalResearch.com: What are the main findings of the study? Answer : There was high quality of evidence that biologic agents are associated with increased risk of all opportunistic infections, but there was no difference in mortality attributed to the opportunistic infections. Patients receiving biologics were twice more likely to develop opportunistic infections (OIs) compared to controls (OR 1.79; 95% CI, 1.17-2.74) with a number needed to harm (NNH) of 582 patients. That means that 1 opportunistic infection  would occur in every 582 patients receiving biologics. The opportunistic infections usually occurred at the commencement of the use of the biological agent and they were not statistically more in patients with a previous exposure to anti-TNF agents as compared to the patients that had never received an anti-TNF agent..

Hanna Sanoff MD, MPH Lineberger Comprehensive Cancer Center Department of Medicine University of North Carolina, Chapel Hill, NCMedicalResearch.com Interview with: Hanna Sanoff MD, MPH Lineberger Comprehensive Cancer Center Department of Medicine University of North Carolina, Chapel Hill, NC MedicalResearch.com: What are the main findings of the study? Dr. Sanoff: We measured p16, a protein that increases with cellular aging, in blood cells of women receiving chemotherapy for breast cancer. We found that a standard course of chemotherapy led to an increase in p16 expression equivalent to what we have previous seen in people over the course of 10-15 years of chronological aging. This increase persisted in cancer survivors an average of three and half years after treatment. (more…)

Beatrice A. Golomb MD, PhD Professor of Medicine Family and Preventive Medicine University of California, San DiegoMedicalResearch.com Interview with: Beatrice A. Golomb MD, PhD Professor of Medicine Family and Preventive Medicine University of California, San Diego MedicalResearch.com: What are the main findings of the study? Dr. Golomb: The main finding is that veterans with Gulf War illness have bioenergetic defects -- dysfunction of mitochondria, the energy producing elements of cells -- that is evident in comparing affected veterans to matched healthy controls. An estimated 1/4 to 1/3 of the ~700,000 US veterans from the 1990-1 Gulf War developed chronic multisymptom health problems that entail fatigue, cognitive and other CNS problems, muscle pain, weakness and exercise intolerance, with high rates of gastrointestinal (especially diarrhea) and neurological problems, and other symptoms - as well as autonomic dysfunction. Evidence suggests these problems have not abated with time. Veterans from other nations that have conducted epidemiological studies, including the UK, Canada, and Australia, also show elevated rates of problems. (more…)

Dr. Paolo Fiorina, MD PhD Assistant Professor, Division of Nephrology, Harvard Medical SchoolMedicalResearch.com Interview with: Dr. Paolo Fiorina, MD PhD Assistant Professor, Division of Nephrology, Harvard Medical School and Dr. Roberto Bassi Post-doctoral research fellow Nephrology Department at Children's Hospital Boston. Dr. Roberto Bassi Post-doctoral research fellow Nephrology Department at Children's Hospital Boston.   MedicalResearch.com: What are the main findings of the study? Dr. Fiorina: It is common knowledge that type 2 diabetes is a worldwide epidemic and that diabetic nephropathy has become the leading cause of renal failure in the western world. One of the main drivers and worsening factors for the diabetic kidney disease is proteinuria associated with various degrees of tubular damage, and unfortunately, therapies to halt or prevent this complication are not available so far. Our findings show that B7-1 when expressed on podocytes (a specific subset of renal cells) determines alterations in podocytes function and morphology, predisposing individuals with T2D to the loss of proteins into the urine. We also demonstrate that Abatacept, an immunomodulatory drug currently employed for the treatment of a variety of autoimmune diseases, is able to specifically target this malignant pathway, preventing podocytes cellular alterations in vitro and proteinuria development in two murine models of diabetic nephropathy in vivo.

Author Interviews, Blood Pressure - Hypertension, Duke, JAMA / 29.03.2014

MedicalResearch.com Interview with: Ann Marie Navar-Boggan, MD, PhD Division of Cardiology, Duke University Medical Center Durham, North Carolina MedicalResearch.com: What are the main findings of the study? Dr. Navar-Boggan: Two groups of adults are really affected by the updated guidelines. First, 13.5 million adults, including one in five adults over the age of 60, were previously considered to have uncontrolled blood pressure but now meet new guideline goals. Next, 14 million adults over the age of 60 (one in four adults in this age group) are currently on blood pressure lowering therapy and meeting the older, more stringent targets. The guidelines state that no changes are necessary in this group, but they may be eligible for reduced therapy, particularly if they have had side effects or difficulty with the therapies they are taking.

Michael J. Pencina, PhD Professor of Biostatistics and Bioinformatics Director of Biostatistics Duke Clinical Research Institute Durham, NC 27710 MedicalResearch.com Interview with: Michael J. Pencina, PhD Professor of Biostatistics and Bioinformatics Director of Biostatistics Duke Clinical Research Institute Durham, NC 27710 MedicalResearch.com: What motivated your research? Dr. Pencina: After the new guidelines were issued last November, we were intrigued by the change in treatment philosophy from that based on cholesterol levels (used by the “old guidelines” known as NCEP ATPIII) to one based on 10-year risk of cardiovascular disease (used by the new AHA-ACC guidelines).  We were curious what the practical consequences of this shift would be. Furthermore, the media quoted a lot of experts making educated guesses on the impact.  We realized that this question can be answered much more precisely based on the NHANES data. (more…)

Michael Laxy Helmholtz Zentrum München German Research Center for Environmental Health Institute of Health Economics and Health Care Management Neuherberg, GermanyMedicalResearch.com Interview with: Michael Laxy Helmholtz Zentrum München German Research Center for Environmental Health Institute of Health Economics and Health Care Management Neuherberg, Germany MedicalResearch.com: What are the main findings of the study? Answer: In patients with type 2 diabetes a high level of self-management behavior was associated with a better glycemic control, i.e. a lower HbA1c level, in the cross-sectional perspective and a reduced mortality over a 12-year period. This effect remained robust after controlling for socio-demographic and disease related factors, including medication. (more…)

MedicalResearch.com Interview with: JeffJeff Niederdeppe Assistant Professor Department of Communication Cornell University. Niederdeppe Assistant Professor Department of Communication Cornell University.   MedicalResearch.com: What are the main findings of the study? Answer: We conducted an Internet-based survey (N = 1319) with a nationally-representative sample of U.S. adults aged 18–64 during the fall of 2012. Americans voiced the highest levels of support for calorie labeling (65%) and removing drinks from schools (62%), and the lowest support for taxes (22%) or portion size restrictions (26%). Americans were evenly split on whether or not they support restricting sugary drink to children (50%) and requiring TV stations to air ads promoting healthy eating and exercise equal to the time used to advertise for sugary drinks (51%). Democrats and those with negative views of soda companies are more likely to support each of these policies. (more…)

Barbara J. Rolls, PhD Department of Nutritional Sciences The Pennsylvania State University, 226 Henderson Building University Park, PA 16802-6501MedicalResearch.com Interview with: Barbara J. Rolls, PhD Department of Nutritional Sciences The Pennsylvania State University, 226 Henderson Building University Park, PA 16802-6501 MedicalResearch.com: What are the main findings of the study? Dr. Rolls:  We found that as we reduced the flake size of a breakfast cereal so that it filled a smaller volume, individuals ate a greater weight and more calories of the cereal. On four occasions, we served a popular wheat flake cereal, or the same weight of cereal crushed to 80%, 60%, or 40% of its volume, to 41 adults for breakfast. As the flake size was reduced, people made reductions in the volume of cereal they poured, but they still took a greater amount of weight and calories. They ended up eating 72 more calories at breakfast when they ate the cereal with the smallest flake size, an increase of 34%. These findings show that variations in food volume due to the size of individual food pieces affect the portion of food that people take, which in turn affects how much they eat. (more…)
Author Interviews, Cancer, Prostate Cancer / 27.03.2014

MedicalResearch.com Interview with: Florence K. Keane, MD Harvard Radiation Oncology Program, Harvard Medical School and Anthony V. D’Amico, MD, PhD Department of Radiation Oncology, Dana Farber Cancer Institute and Brigham and Women's Hospital, Boston, Massachusetts MedicalResearch.com: What are the main findings of the study: Answer: Patients with unfavorable intermediate-risk prostate cancer (PC) [1] have an increased risk of PC-specific mortality (PCSM) after radiotherapy (RT) with or without androgen suppression therapy (AST) compared to favorable intermediate-risk patients [2,3]. We provided validation for this prognostic subdivision using mature data with a median follow-up of 14.3 years from a prospective randomized trial comparing RT alone with RT and 6 months of AST [4].  We also assessed the risk of PCSM in patients with unfavorable intermediate-risk PC compared with high-risk prostate cancer. Our main findings were as follows.
  • First, there were no prostate cancer deaths observed in favorable intermediate-risk patients, despite 50% receiving RT alone.
  • Second, there was not a statistically significant difference in the risk of PCSM in men with unfavorable intermediate-risk prostate cancer compared to men with high-risk PC after randomizing for age, comorbidities and treatment arm. While it is possible that a difference may emerge with longer follow-up, these results suggest that some men with unfavorable intermediate-risk PC may harbor occult GS 8-10 disease and could benefit from a 3.0-Tesla multiparametric MRI and targeted biopsy to rule out GS 8-10 disease.

Dr. Pilote: Our study found that in patients with atrial fibrillation (AF) undergoing dialysis, warfarin use, compared to no-warfarin use, did not reduce the risk for stroke (adjusted hazard ratio (HR): 1.14, 95% confidence interval (CI): 0.78 to 1.67) but it was associated with a 44% higher risk for bleeding event (adjusted HR: 1.44, 95% CI: 1.13 to 1.85). However, warfarin use in non-dialysis patients with AF was associated with a 13% lower risk for stroke (adjusted HR: 0.87, 95% CI: 0.85 to 0.90) and only a 19% higher risk for bleeding event (adjusted HR: 1.19, 95% CI: 1.16 to 1.22).

Laureen Smith, PhD Associate Professor College of Nursing, The Ohio State University Columbus, OH 43210MedicalResearch.com Interview with: Laureen Smith, PhD Associate Professor College of Nursing, The Ohio State University Columbus, OH 43210 MedicalResearch.com: What are the main findings of the study? Dr. Smith: Daily sugar-sweetened beverage decreased significantly by about 1 serving per day. Also weekly consumption decreased from an average of over 4 days per week to about 2 ½ days per week. Generally, the teens were drinking the beverages fewer days per week and less servings on the days they did consume them. These changes were maintained on their own for a month after the intervention ended. Water consumption increased nearly 20 percent immediately post intervention and continued to increase at 30 days post-intervention. (more…)

Dr Damian Hoy University of Queensland School of Population Health Herston, AustraliaMedicalResearch.com Interview with: Dr Damian Hoy University of Queensland School of Population Health Herston, Australia

MedicalResearch.com: What are the main findings of the study? Dr. Hoy: The study was part of the Global Burden of Disease 2010 study, which was conducted by the University of Queensland, Harvard University, Johns Hopkins University, University of Washington, and hundreds of disease experts throughout the globe. It is the largest ever public health study. It compared the overall burden (in terms of both death and disability) of the most common 291 diseases/conditions in the world. Low back pain was found to cause more global disability than any other disease/condition. If this is something you are going through, it may be worth knowing that marijuana strains for back pain is one of the most powerful remedies. You've possibly tried everything in the shop and over the counter medicine. So why not give this a go and see how you get on. There's no harm in trying. Global disability from low back pain is increasing. There is an urgent need for global, regional and national agencies to pay far greater attention to the disability caused by low back pain. In the developed world there are low back pain therapy treatments available whereas, in the developing world things aren't as accessible. (more…)

Yun Gong, M.D. Associate Professor Department of Pathology, Unit 53 M D Anderson Cancer Center Houston, TX 77030MedicalResearch.com Interview with: Yun Gong, M.D. Associate Professor Department of Pathology, Unit 53 M D Anderson Cancer Center Houston, TX 77030 MedicalResearch.com: What are the main findings of the study? Dr. Gong:  Androgen receptor (AR) was positive in 39% of the inflammatory breast cancer (IBC) tumors, approximately one-third of estrogen receptor (ER)-negative and progesterone receptor (PR)-negative tumors and 42.6% triple-negative tumors. AR positivity was significantly associated with lymphovascular invasion but not with other clinicopathologic parameters. There was a trend toward association between AR expression and PR expression. Univariate survival analysis indicated that patients with AR-negative/ER-negative tumors had significantly worse overall survival and disease-specific survival than the patients with tumors showing other combinations of AR/ER status (i.e., AR-negative/ER-positive, AR-positive/ER-negative,  or AR-positive/ER-positive). Notably, the study was performed using post-neoadjuvant IBC surgical specimens. (more…)

MedicalResearch.com Interview with: Shelley S. Magill, M.D., Ph.D. From the Centers for Disease Control and Prevention Emory University School of Medicine Atlanta, Georgia MedicalResearch.com: What are the main findings of the study? Dr. Magill: The results of this survey show that healthcare-associated infections continue to be a threat to patient safety in U.S. acute care hospitals. Among the more than 11,000 patients included in the survey, approximately 4% (or 1 in 25) had at least one healthcare-associated infection at the time of the survey. We used these results to develop national estimates of healthcare-associated infections. We estimated that in 2011, there were approximately 721,800 healthcare-associated infections in U.S. acute care hospitals. The most common types of infections were surgical site infections (SSIs), pneumonias, and gastrointestinal infections. (more…)

MedicalResearch.com Interview with: Marie Lund MD, PhD student Department of Epidemiology Research København S | Denmark MedicalResearch.com: What are the main findings of the study? Dr. Lund: We found macrolide use in infants to be associated with a 30-fold increased risk of infantile hypertrophic pyloric stenosis (IHPS) with use during the first two weeks after birth and a lower, but significantly increased threefold risk with use during days 14 to 120. Similarly, there was a more than three-fold increased risk of IHPS associated with maternal macrolide use during the first two weeks after birth, but no increased risk with use thereafter. Finally, we found a possible modest association between maternal macrolide use during weeks 28 to birth and infantile hypertrophic pyloric stenosis. (more…)

Tim Bongartz, M.D. Associate Professor of Medicine Department of Rheumatology Mayo Clinic, MinnesotaMedicalResearch.com Interview with: Tim Bongartz, M.D. Associate Professor of Medicine Department of Rheumatology Mayo Clinic, Minnesota MedicalResearch.com: What are the main study findings? Dr. Bongartz:  Dual-energy computed tomography (DECT) is an imaging methods that has been in use for many years to classify the material of renal stones. Our study demonstrates that this technology can be useful in identifying monosodium urate deposits in and around joint, allowing to diagnose patients with gout with overall high sensitivity and specificity. Importantly, a stratified analysis of patient subgroups revealed that DECT is less accurate in diagnosing patients with a first flare of gout, emphasizing the importance of careful patient selection when using this new technology. In a "diagnostic-yield" substudy, we explored the question how much DECT could contribute to correctly diagnose patients where clinicians did have a high level of suspicion for gout, but synovial fluid aspiration results came back negative. In about a third of these patients with negative routine testing, we could confirm a diagnosis of gout through use of DECT. (more…)

Dr. Kristy Ward Department of Reproductive Medicine UCSD School of MedicineMedicalResearch.com Interview with: Dr. Kristy Ward Department of Reproductive Medicine UCSD School of Medicine   MedicalResearch.com: What are the main findings of this study? Dr. Ward: As the second leading cause of preventable death, obesity is one of the nation’s most serious public health problems.  Over two-thirds of the US population is currently overweight or obese and the prevalence continues to increase.  A number of studies have linked obesity with an overall elevated risk of cancer and with many individual cancer types. Among obesity related cancers in women, endometrial cancer is most strongly associated with increasing body mass, with 39% of cases in the US attributable to obesity. In patients with clinically severe obesity (BMI ≥ 40 kg/m2), bariatric surgery results in rapid weight loss and has greater long-term success when compared to non-surgical weight loss methods. Surgical weight loss procedures have been found to reduce obesity-related comorbidites and improve outcomes in clinically severe obese populations. In addition to improved cardiovascular risk factors and mitigation of physical symptoms, there is increasing evidence that cancer risk is reduced after bariatric surgery. (more…)

Dr. Karolina Sjöberg Jabbar, MD, Medicine Policlinic II, Bla Straket 5, Sahlgrenska University Hospital Gothenburg, SwedenMedicalResearch.com Interview with Dr. Karolina Sjöberg Jabbar, MD, Medicine Policlinic II, Bla Straket 5, Sahlgrenska University Hospital Gothenburg, Sweden   MedicalResearch.com: What are the main findings of the study? Answer: The main finding of this study is that the presence of mucin proteins in pancreatic cyst fluid, as evaluated by mass spectrometry, can predict with high accuracy (97%) which pancreatic cysts contain premalignant and malignant tumours. This is important, given that pancreatic cystic lesions are an increasingly common incidental finding on imaging. While most of them pose no threat to the patient, a minor proportion has malignant potential, and may be considered precursors to pancreatic cancer. (more…)

MedicalResearch.com Interview with Mònica Bulló PhD Human Nutrition Unit Department of Biochemistry & Biotechnology IISPV  School of Medicine Rovira i Virgili University Sant Llorenç, Spain MedicalResearch.com: What are the main findings of the study? Dr Bulló: There is some evidence that different dietary forms of vitamin K could exert varying effects on health, however no study to date has simultaneously evaluated the potential effects of the main vitamin K forms on cancer and cardiovascular mortality. We conducted a prospective, epidemiologic study involving 7,216 elderly subjects at high cardiovascular risk who were followed for about 5 years.The results of the present study show, for the first time that an increase in dietary intake of both forms of vitamin K is related to a lower risk of cardiovascular mortality, cancer mortality or all-cause mortality.

MedicalResearch.com Interview with Michael Kimlin Professor of Cancer Prevention Research Institute of Health and Biomedical Innovation Queensland University of Technology AustraliaMichael Kimlin Professor of Cancer Prevention Research Institute of Health and Biomedical Innovation Queensland University of Technology Australia MedicalResearch.com: What are the main findings of the study? Answer: The main findings of this study were that women who where classified as having the highest level of sun exposure in our sample had a significantly larger drop in blood folate levels compared to women with lower sun exposures. This was quite a powerful finding, as all women were supplemented with folate and tested so that so that we knew that each sun exposure group had similar average levels of blood folate at the start of the study. We then measured their sun exposure over a week and took a sample of blood at the end of this week to see how the degree of sun exposure affected folate levels. (more…)

Dr. Ling:  We followed a sample of smokers from a nationally representative panel for one year.  We found that there was no difference in the rate of quitting between smokers who used an e-cigarette and those who did not. Put another way, smokers who had used e-cigarettes at the beginning of the study were equally likely to have quit smoking one year later as those who did not use e-cigarettes. There was no relationship between e-cigarette use and quitting even after taking into account measures of tobacco dependence (number of cigarettes smoked per day, how early in the day a smoker has his first cigarette) and intention to quit smoking.

Craig A. Anderson, Distinguished Professor Director, Center for the Study of Violence Department of Psychology Iowa State University Ames, IA 50011-3180MedicalResearch.com Interview with: Craig A. Anderson, Distinguished Professor Director, Center for the Study of Violence Department of Psychology Iowa State University Ames, IA 50011-3180 MedicalResearch.com: What are the main findings of the study? Dr. Anderson: There are three main findings from this long-term study of violent video game effects. 1. Over time, repeated play and practice of violent video games led to an relative increase in aggressive thought patterns and in physical aggression. 2. As predicted by social-cognitive theoretical models, the violent video game effect on physical aggression was directly linked to the increase in aggressive thought patterns. That is, one key reason why repeated exposure to violent video games increases aggression is because such exposure changes the way children and adolescents think about people and events that occur in their lives. In a sense, their personality changes, so that they perceive more hostility around them and come to view physically aggressive behavior as a proper solution to even minor conflicts and provocations. 3. These effects of repeated exposure to violent video games were quite general across types of people. Boys and girls, younger children and older adolescents, high aggressive and low aggressive children, all showed pretty much the same effects. In other words, no subgroup was immune to the harmful effects of violent video games. (more…)
