Dr. Lydia Pace, MD, MPH Division of Women’s Health, Brigham and Women’s Hospital Boston, MassachusettsMedicalResearch.com Interview with: Dr. Lydia  Pace, MD, MPH Division of Women’s Health, Brigham and Women’s Hospital Boston, Massachusetts MedicalResearch.com: What are the main findings of the study? Dr. Pace: We reviewed the existing literature about the benefits and harms of mammography, focusing on the reduction of breast cancer deaths associated with mammography, as well as the two most often-discussed harms: false positive results and overdiagnosis. We also reviewed the literature about interventions to help patients make informed decisions. We found that the literature suggests that routine screening mammography does reduce mortality associated with breast cancer, across all age groups. However, it is also associated with high rates of false positive results, and considerable rates of overdiagnosis. Overdiagnosis is the most concerning potential risk of mammography screening. Overdiagnosis is the detection of a tumor through screening that would never have caused problems for a patient. It occurs either because of a very slow-growing tumor, or because a woman has medical problems (or is old enough) such that she will likely die of another cause before the cancer became apparent. Overdiagnosis is concerning because we cannot know when a cancer is overdiagnosed, and thus a patient who is overdiagnosed will receive unnecessary treatment for cancer. The scientific literature on mammography is complex, and there are important limitations to the studies both of mammography’s benefits and harms. However, we feel that the best available data suggest that among 10,000 50 year old women undergoing annual mammography for 10 years, 5 deaths will be averted through screening mammography, while about 6130 women will experience at least one positive result. Furthermore, there is about a 19% chance that, if that woman is diagnosed with cancer detected by a mammogram, that cancer is one that would never have caused her problems. Lastly, our review showed that we need more studies to guide us in how an individual woman’s risk should dictate her mammography decisions, and how to support women in making those decisions. However, we know that most women with higher risk for breast cancer will experience higher benefit from mammography screening. (more…)

Shanthi Srinivasan, M.D. Associate Professor of Medicine Division of Digestive Diseases Department of Medicine Emory University Atlanta, GA 30322MedicalResearch.com Interview with: Shanthi Srinivasan, M.D. Associate Professor of Medicine Division of Digestive Diseases Department of Medicine Emory University Atlanta, GA 30322   MedicalResearch.com: What are the main findings of the study? Dr. Srinivasan: The main findings of this study are that the neurotrophic factor GDNF is was able to protect against the weight gain induced by mice on a high fat diet. The mice that had overexpression of GDNF showed less weight gain while eating the same high fat diet as the control mice. GDNF seems to have effects on the genes regulating fat metabolism and energy expenditure and this could be the mechanism of prevention of weight gain. (more…)

Daniel J. Elliott, M.D., MSCE, FACP Associate Chair of Research Department of Medicine and Research Scholar Value Institute, Christiana Care Health SystemMedicalResearch.com Interview with: Daniel J. Elliott, M.D., MSCE, FACP Associate Chair of Research Department of Medicine and Research Scholar Value Institute, Christiana Care Health System MedicalResearch.com: What are the main findings of the study? Dr. Elliott: The optimal workload for hospitalists has been a question since the earliest days of hospital medicine. However there has been very little empirical evidence to understand the relationship between workload and outcomes. The objective of our study was to determine the association of daily workload for hospitalists on the efficiency, quality, and cost of care.  We analyzed data from a single private practice hospitalist group at a community-based health system between February 2008 and January 2011. Our research showed that both length of stay and cost increased for patients as hospitalist workload increased. At the same time, our research showed that workload did not affect patient satisfaction as measured by HCAHPS scores or quality and safety outcomes including admissions, rapid response team activation and mortality.

Answer: Our studies have identified two main findings: Firstly that the size or frequency of the meal doesn’t affect the calories we burn in a day, but what matters most for losing weight is counting calories. Secondly, by carrying more weight, more endotoxin enters the circulation to cause inflammation and eating more often will exacerbate this risk which has been linked to metabolic diseases such as type-2 diabetes.

Professor Rodney Sinclair University of Melbourne and Epworth Hospital Melbourne, VIC, AustraliaMedicalResearch.com Interview with: Professor Rodney Sinclair University of Melbourne and Epworth Hospital Melbourne, VIC, Australia   MedicalResearch.com: What are the main findings of the study? Answer: Activation of Wnt signalling promoted hair growth and fat growth.  Inhibition of Wnt signalling reduces fat growth and hair growth.  We looked at the fat layer on the scalp.  It was reduced by 50% over the bald areas of alopecia areata.  The patch of alopecia areata we looked at was new- only appeared a few days earlier and so the changes in fat thickness are rapid. What is interesting is that the fat layer is dynamic, and significant fluctuations can occur in a rapid period of time in sync with the hair cycle.  It is also interesting that ligands for BMP6 and IGF2 are pro-adipogenic. There are a couple of bigger questions that earlier media reports did not focus on- namely upstream factors regulating the hair cycle clock and the beauty of synchronization of fat and hair growth for seasonal thermal insulation.

Rogers, PhD, MS Research Associate Professor Research Director, Patient Safety Enhancement Program Department of Internal Medicine University of Michigan Ann Arbor, MI  48109-2800 MedicalResearch.com: What are the main findings of the study? Dr. Rogers: The risk of serious infection is considerably elevated after receiving allogeneic (donor) red blood cell transfusions.  For every 38 patients under consideration for transfusion, 1 patient could be spared an infection if more restrictive hemoglobin thresholds were used.  When patients were given transfusions only after their hemoglobin fell below 7.0 g/dL, 1 patient avoided an infection of every 20 patients treated.  The results were most consistent in elderly patients receiving hip and knee replacement surgeries.  Their risk of infection decreased by 30% when lower hemoglobin thresholds were used.

Rosebud O Roberts, M.B., Ch.B. Professor of Epidemiology Professor of Neurology Mayo ClinicMedicalResearch.com Interview with: Rosebud O Roberts, M.B., Ch.B. Professor of Epidemiology Professor of Neurology Mayo Clinic MedicalResearch.com: What are the main findings of the study? Dr. Roberts: We found that among persons 70 years and older, people with type 2 diabetes had a reduced glucose uptake (hypometabolism) in  brain cells.  We also found a similar association for people without type 2 diabetes but who had elevated hemoglobin A1c levels levels at the time of enrollment (HBA1c is a measure of glucose control, and represents the average blood glucose levels over a 3 month period). However, we did not find an association of diabetes with increased brain amyloid accumulation.  Our findings were based on an investigation of the association of type 2 diabetes with markers of brain pathology: brain hypometabolism was assessed by 18F-fluorodeoxyglucose positron emission tomography [PET] and amyloid accumulation was assessed by 11-C Pittsburgh Compound B PET imaging.

MedicalResearch.com Interview with: dr_karen_e_lasser Karen E Lasser, MD MPH Associate Professor of Medicine Boston University School of Medicine, Boston, MA MedicalResearch.com: What are the main findings of the study? Dr. Lasser: After controlling for variables that could affect the risk of readmission, we found that:
  1. There was a slightly increased risk of all-cause readmission in Massachusetts (MA) relative to control states (New York and New Jersey) post-reform.
  2. Racial and ethnic disparities in all-cause readmission rates did not change in MA relative to control states.
  3. However, both blacks and whites in counties with the highest uninsurance rates had a decreased risk of readmission following MA health reform relative to blacks and whites in counties with lower uninsurance rates.

Mary E. Arthur, MD Cardiothoracic and ICU Anesthesia Department of Anesthesiology and Perioperative Medicine Georgia Regents University, Augusta, GAMedicalResearch.com interview with: Mary E. Arthur, MD Cardiothoracic and ICU Anesthesia Department of Anesthesiology and Perioperative Medicine Georgia Regents University, Augusta, GA   MedicalResearch.com: What made this cardiac case challenging? Dr. Arthur: The left ventricle of our patient’s heart was functioning very poorly, and he required maximum pharmacologic support after he was weaned from cardiopulmonary bypass at the end of a 4-vessel coronary artery bypass graft procedure. His blood pressure and cardiac output were extremely low and his heart was not pumping well and so we put him back on bypass. Under routine circumstances, using an intra-aortic balloon pump is the next logical step, however it was inadvisable in this patient because he had moderate aortic insufficiency (a leaky aortic valve).

Stein, M.D., Ph.D. FRCP(C), FCAP Metabolic and Atherosclerosis Research Center Cincinnati, OH 45225,   MedicalResearch.com: What are the main findings of the study? Dr. Stein: The study which is the first 52 week randomized double blind trial of a PCSK9 to report results (all others have been 12 weeks) demonstrated that the excellent LDL-C reductions of 55-60% seen at 12 weeks are maintained through 52 weeks, with no fall off in patient compliance, tolerability of efficacy. It also demonstrated that with longer treatment no new or unexpected side effects. The study also had a unique design in that prior to randomization to the PCSK9 inhibitor (evolocumab) or placebo patients had a run in period during which time they were assigned, based on NCEP-ATP III criteria, to appropriated background therapy which ranged from diet only, to atorvastatin 10 mg a day, to atorvatatin 80 mg a day or atorvastatin 80 mg a day plus ezetimibe - reflecting how these patients are treated in practice. Only then if their LDL-C was still above 75 mg/dL were they randomized into the treatment part of the study with the new drug. The study showed that irrespective of background therapy the reduction with evolocumab was consistent. (more…)

Kulynych Center for Memory & Cognition Research Department of Internal Medicine Division of Gerontology and Geriatric Medicine Wake Forest School of Medicine Medical Center Boulevard, Winston-Salem, NC  27157-1207 MedicalResearch.com: What are the main findings of the study? Dr. Hughes: This study is a follow-up to our recent paper that showed a novel relationship between arterial stiffness (commonly measured by pulse wave velocity) and the presence and extent of amyloid deposition in the brain, a hallmark of Alzheimer’s disease. For this study, we repeated brain amyloid imaging (using the Pittsburgh Compound B during PET imaging) in order to look for predictors of change in amyloid over two years in n=81 elderly adults aged 80+ and free from dementia. We observed that measures of systemic arterial stiffness (e.g. brachial ankle pulse wave velocity) was strongly associated with the extent of amyloid deposition in the brain at both baseline and follow-up. The change in brain amyloid accumulation over two years resulted in an increase in in the number of participants with Alzheimer’s-like (amyloid-positive) from 45% at baseline to a surprising 75% after just two years. This change in brain amyloid accumulation over two years was strongly related to having greater central stiffness (as measured by carotid femoral pulse wave velocity). These relationships between arterial stiffness and brain amyloid deposition were independent of the effects of age, gender, body mass index, antihypertensive medication use and even current blood pressure.

MedicalResearch.com Interview with: M.S. ReimersM.S. Reimers, MD PhD Student and Dr. Jan Liefers MD Department of Surgery, Leiden University Medical Center, Leiden, the Netherlands MedicalResearch.com: What are the main findings of the study? Answer: Aspirin use was associated with an improved survival, as we have published before when investigating this cohort (Bastiaannet et al, Brit J Cancer 2012/ Reimers et al. J Am Geriatr Soc. 2012. In this study we have focused on investigating which patients will benefit from aspirin treatment by investigating some tumor markers, such as PTGS2 expression, HLA class I expression and PIK3CA mutation status. Interestingly, only patients with HLA class I expression on their tumor membrane will benefit from aspirin treatment and have a better outcome. We raise the hypothesize that aspirin inhibits platelet aggregation to circulating tumors cells. By interfering with this process, the metastatic potential of these circulating tumour cells is inhibited, thereby preventing metastasis and colon cancer death.HLA class I expression might be needed for signalling between platelets and circulating tumor cells. If this hypothesis is confirmed by others or in vitro studies, than this might explain the finding that aspirin seems not only beneficial as an adjuvant therapy for colorectal cancer patients, but also for patients with other malignancies (oesophagus, breast, etc). Interestingly, preliminary findings from our team investigating aspirin use in oesophageal cancer also showed that aspirin use in these tumors was associated with an improved survival. (more…)

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..

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. 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.

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.

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…)
