Professor Emrah Düzel Director, Institute of Cognitive Neuroscience University College LondonMedicalResearch.com Interview with: Professor Emrah Düzel Director, Institute of Cognitive Neurology and Dementia Research, OvG Univ. Magdeburg, Germany Institute of Cognitive Neuroscience University College London Medical Research: What are the main findings of the study? Professor Düzel: We found that even in old age, intensive and long-term (3 months) aerobic exercise can improve blood flow in the hippocampus, a brain structure that is of critical importance for memory.  The increase in blood flow is evident during a resting state and this means that the exercise improves the overall perfusion of the hippocampus. Such effects had previously only been reported in young adults. As previously observed in young adults, the change in blood flow after exercise is related to the improvement of specific memory skills. We found the closest relationship between improved blood flow and recognition memory for complex objects. This is interesting because this type of memory is likely to benefit from “pattern separation”, a process that in animal studies of exercise is tightly associated with hippocampal neurogenesis. However, we also found that the exercise-related improvement in hippocampal blood flow and in recognition memory was absent in the older seniors of our study cohort. Those  who were beyond 70 did not show any improvement. We reasoned that this may have been due to higher levels of stress in the older seniors. Therefore, we investigated whether elevated serum cortisol levels dampened the benefits of exercise in the older seniors. But this was not the case making it unlikely that stress levels can account for these findings. (more…)
Author Interviews, Cost of Health Care, JAMA, University of Pennsylvania / 22.10.2014

Dr. Harald Schmidt, MA, PhD Assistant Professor, Department of Medical Ethics and Health Policy Research Associate, Center for Health Incentives and Behavioral Economics Perelman School of Medicine University of Pennsylvania Philadelphia, PA 19104-3308MedicalResearch.com Interview with Dr. Harald Schmidt, MA, PhD Assistant Professor, Department of Medical Ethics and Health Policy , Research Associate, Center for Health Incentives and Behavioral Economics, Perelman School of Medicine University of Pennsylvania Philadelphia, PA 19104-3308 Medical Research: What are the main findings of the study? Dr. Schmidt: We reviewed currently available policies for aligning cost and quality of care. We focused on interventions are similar in their clinical effectiveness, have modest differences in convenience, but pose substantial cost differences to the healthcare system and patients. To control health care costs while ensuring patient convenience and physician burden, reference pricing would be the most desirable policy. But it is currently politically unfeasible. Alternatives therefore need to be explored. We propose the novel concept of Inclusive Shared Savings, in which physicians, the healthcare system, and, crucially, patients, benefit financially in moving more patients to lower cost but guideline concordant and therapeutically equivalent interventions.

Carolyn J. Crandall, MD, MS Professor of Medicine David Geffen School of Medicine at University of California, Los Angeles UCLA Medicine/GIM Los Angeles, CA 90024MedicalResearch.com Interview with: Carolyn J. Crandall, MD, MS Professor of Medicine David Geffen School of Medicine at University of California UCLA Medicine/GIM Los Angeles, CA 90024 Medical Research: What are the main findings of the study? Dr. Crandall: Clinical guidelines recommend that women aged ≥ 65 years should be screened for osteoporosis.  However, for younger postmenopausal women aged between 50 and 64 years, the United States Preventive Services Task Force (USPSTF) recommends osteoporosis screening for women who have a 10-year predicted risk of osteoporosis fracture that is ≥9.3%.  We tested the ability the USPSTF strategy, and two other strategies (called OST and SCORE), to distinguish between women who did and did not experience a fracture in the subsequent 10 years.  We found that the USPSTF strategy did not identify the majority of who experienced osteoporotic fracture in the subsequent 10 years.  Especially in women aged 50-54 years, the USPSTF strategy identified fewer than 5% of women who experienced fracture over 10-year follow-up.

Heart Disease / 21.10.2014

MedicalResearch.com Interview with: Graham Peigh, BA Thomas Jefferson University Medical Research: What are the main findings of the study? Response: The main findings of our study show that extracorporeal cardiopulmonary resuscitation (E-CPR) can provide recovery when a patient is unresponsive to conventional CPR. In our sample of 24 patients, 13 survived ECMO, and 7 were successfully discharged from the hospital. Major meta analytic studies have shown that in-hospital CPR yields a discharge rate of under 20%, and our study presents results which demonstrate that E-CPR provides a method by which those survival figures can be increased. Importantly, our study also showed that vital organ function among ECMO survivors was maintained. All13 patients had improved or unchanged kidney and liver function, and 12/13 had improved or unchanged metabolic function. After using standard hypothermia protocols, all seven hospital survivors had full neurological recovery. This study differs from the majority of other studies on E-CPR because our institution does not have a dedicated E-CPR/Code team available to perform E-CPR 24/7. We believe that our results are thus generalizable to other academic institutions, which, like ours, have the capability to perform E-CPR, but are only able to do so during on-hours when physicians, perfusionists, and ECMO materials are available.

Peter J. Mazzone, MD, FCCP MPH Director of the Lung Cancer Program for the Respiratory Institute Cleveland ClinicMedicalResearch.com Interview with: Peter J. Mazzone, MD, FCCP MPH Director of the Lung Cancer Program for the Respiratory Institute Cleveland Clinic Medical Research: What are the main findings of this study? Dr. Mazzone:   There were 2 parts to this study. In the first part we looked at how the breath collection instrument and sensor were performing and made adjustments to both in order to optimize its performance. In the second part we used the improved device and sensor to see if we could accurately separate a sensor signal of our patients with lung cancer from those without lung cancer. We found good separation of lung cancer from non-cancer breath signals, and very good separation of signals of one type of lung cancer from another. We have concluded that a colorimetric sensor array based breath test is capable of separating those with lung cancer from those without. (more…)

Dr. Iris L. Romero MD MS Associate Professor of Obstetrics & Gynecology, Section of General Gynecology The University of Chicago Medicine Chicago, ILMedicalResearch.com Interview with: Dr. Iris L. Romero MD MS Associate Professor of Obstetrics & Gynecology, Section of General Gynecology The University of Chicago Medicine Chicago, IL   Medical Research: What are the main findings of the study? Dr. Romero: There is increasing epidemiologic and preclinical data indicating that the commonly used diabetic drug, metformin, may have anticancer effects. In ovarian cancer, in 2011 in Obstetrics & Gynecology we reported that in a retrospective cohort ovarian cancer patients that were using metformin had increased survival compared to those not using mefomrin. In this study, we expand on those findings by testing whether metformin can prevent ovarian cancer or improve response to chemotherapy in mouse models. In a prevention study, we found that mice treated with metformin before cancer was initiated developed less tumor than those treated with placebo. In a treatment study, in vitro, metformin increased the cytotoxic effect of paclitaxel. In addition, using a genetic mouse model we show that the combination of paclitaxel plus metformin results in a greater tumor reduction than either drug used alone. (more…)

Edward I. Ginns, MD, PhD, Director Program in Medical Genetics and Lysosomal Disorders Treatment and Research Program University of Massachusetts Medical School Reed Rose Gordon Building, Room 137 Shrewsbury, MA 01545MedicalResearch.com: Interview with: Edward I. Ginns, MD, PhD, Director Program in Medical Genetics and Lysosomal Disorders Treatment and Research Program University of Massachusetts Medical School Reed Rose Gordon Building, Room 137 Shrewsbury, MA 01545 Medical Research: What are the main findings of the study? Dr. Ginns: Our study identified that sonic hedgehog signaling, an important brain pathway, is involved in bipolar affective disorder. This finding shows a mechanism and provides new targets for drug development. It suggests that sonic hedgehog signaling can be modulated to help manage bipolar symptoms in adults by using drugs already being studied in clinical trials for other medical conditions. The new findings were uncovered by decades of translational research in the Old Order Amish families of Pennsylvania, where in a few special families in the Amish Study there is a high incidence of both bipolar disorder and a rare genetic dwarfism, Ellis van‐Creveld (EvC) syndrome. No person with EvC had bipolar disorder despite forty years of documented research across multiple generations, suggesting that the genetic cause of this rare dwarfism was protective of bipolar affective disorder.

Suarez-Almazor, MD, PhD Barnts Family Distinguished Professor Chief, Section of Rheumatology & Deputy Chair, Dept. of General  Internal Medicine UT MD Anderson Cancer Center Houston, TX Medical Research: What are the main findings of the study? Response: Our study established that unplanned hospitalization among elderly patients with GI cancer are very common – 93 events per 100-person years. Certain characteristics were found to have an increased risk for an unplanned hospitalization in our cohort, namely: older age, black race, advanced disease, higher comorbidity score, residing in poor neighborhoods and dual eligibility for Medicare and Medicaid. Esophageal and gastric cancer had the highest risk for unplanned hospitalization among all GI cancer types. Some of the observed reasons for unplanned hospitalization were potentially preventable and related to the patient’s comorbid illness. (more…)

Katz, MD, MPH, FACPM, FACP Director, Yale University Prevention Research Center Griffin Hospital   Medical Research: What are the main findings of the study? Dr. Katz: We did not see any adverse effects of short-term, daily egg ingestion in adults with established coronary artery disease. Medical Research: What was most surprising about the results? Dr. Katz: Eggs are routinely banned from 'heart healthy diets.'  in particular eggs are always absent from cardiac care units, with egg beaters substituting.  However, these same units routinely serve products with refined starch and added sugar.  The scientific basis for excluding eggs from diets to improve cardiac health has long been suspect.  Here, we show that in the short term at least, there are no discernible harms of daily egg ingestion even in adults with heart disease.

Dr. Brent M. Egan MD Adjunct Professor Medical University of South CarolinaMedicalResearch.com Interview with: Dr. Brent M. Egan MD Professor of Medicine University of South Carolina School of Medicine Greenville Senior medical director of the Care Coordination Institute Greenville, South Carolina Medical Research: What are the main findings of the study? Dr. Egan: The study was undertaken to determine progress toward the Healthy People 2020 goals of controlling hypertension or high blood pressure in 61.2% of all adults with the condition. What we found is that hypertension control has changed very little from 2007 through 2012. In 2011-2012, an estimated 51.2% of all hypertensive adults were controlled, which is 10% below the 2020 goal.  The analysis indicated that healthcare insurance and at least two healthcare visits yearly were related to both the likelihood that hypertension would be treated and controlled.

Marie C. Leger, MD, PhD Ronald O. Perelman Department of Dermatology New York University School of Medicine, New YorkMedicalResearch.com Interview with Marie C. Leger, MD, PhD Ronald O. Perelman Department of Dermatology New York University School of Medicine, New York Medical Research: What are the main findings of the study?
What was most surprising about the results?

 Dr. Leger: Alopecia areata is a T-cell mediated autoimmune disease. As such, there was initially hope that inhibiting the helper T cell cytokine TNF-α could effectively treat this condition. This has not been shown to be the case—in fact, one open-label study of etanercept in 17 patients with moderate to severe alopecia showed no hair regrowth and even worsening of alopecia in several subjects. There have been many other case reports in the dermatologic literature of TNF-α inhibitors causing alopecia areata. In contrast, our case report presents a patient who very clearly grew hair on adalimumab—its strength lies in the fact that her hair loss and regrowth were replicated on withdrawal and rechallenge with the medication. Our patient’s paradoxical response to adalimumab complements other literature suggesting that there are genetic variations in the way a patient’s immune system responds to TNF-α inhibitors. In different individuals, these medications can either treat or cause conditions such as psoriasis or lupus. It seems that this is also the case with alopecia areata. (more…)

Response: From 2002-2012, a child younger than 6 years old experienced an out-of-hospital medication error every 8 minutes. That’s a total of 696,937 during the study period, or 63,358 per year. Almost all happened at the child’s residence. The rate and number of errors decreased with increasing age. Analgesics were the mostly commonly involved medications (25.2%), followed by cough and cold medications (24.6%). More than 1 in 4 (27%) of the errors happened when a child inadvertently took or was given medication twice. Errors also happened when children took or were given an incorrect dose, when medication measurements were confused, and when the wrong medication was taken or given. (more…)

MedicalResearch.com Interview with: Dr Tsai Chung-Li Graduate Institute of Biostatistics, College of Management, China Medical University,Taichung, Taiwan and Dr. Hsiao-Chuan Lin Department of Public Health, College of Public Health, and Department of Pediatrics, China Medical University, Taichung, Taiwan Medical Research: What are the main findings of the study? Response: We conducted a nationwide population-based cohort study that included two groups. Children with enterovirus infection (aged < 18 years) during 2000-2007 were identified and followed up until December 31, 2008 or until first occurrence of type 1 diabetes. The group without enterovirus infection comprised half of all insured children of the same age and without a diagnosis of enterovirus infection. By use of frequency-matching with sex and birth year, children in the group with enterovirus were selected from those eligible. This nationwide retrospective cohort study found:
  • type 1 diabetes is positively correlated with enterovirus infection in patients younger than 18 years.
  • the incidence rate of type 1 diabetes was lower in the non-enterovirus than the enterovirus group (4 vs 6 per 100,000 person-years; incidence rate ratio 1.48 [95% CI 1.19, 1.83]).
  • children that have been infected with enterovirus are 48% more likely to have developed type 1 diabetes.
  • the risk of developing type 1 diabetes is 2.18 times greater among children aged 10 years and older than among those aged younger than 1 year.

Adrian Baranchuk MD FACC FRCPC Associate Professor of Medicine Director, EP Training Program Queen's University Kingston, Ontario, CanadaMedicalResearch.com Interview with: Adrian Baranchuk MD FACC FRCPC Associate Professor of Medicine Director, EP Training Program Queen's University Kingston, Ontario, Canada Medical Research: What are the main findings of the study? Dr. Baranchuk: In this study, we investigated whether obstructive sleep apnea increases the risk of atrial fibrillation after coronary artery bypass surgery. We found the risk to increase by approximately two-fold for patients with obstructive sleep apnea, suggesting that this disease is a strong predictor of atrial fibrillation after coronary artery bypass surgery. We also found that the risk increases in patients with more severe obstructive sleep apnea. This is an important association to explore since atrial fibrillation after coronary artery bypass surgery increases patient mortality, the risk of stroke, hospital stay, healthcare costs, and has substantial burden on patients and their families. It is also a common complication of the surgery, occurring in up to half of the patients. Knowing which factors increase its risk gives us a better understanding of how to manage it and mitigate its negative consequences. (more…)

MedicalResearch.com Interview with: John A. Naslund, MPH – PhD Student at The Dartmouth Institute for Health Policy and Clinical Practice, Dartmouth College, Hanover, NH Stuart W. Grande, PhD, MPA – Post–doctoral fellow at The Dartmouth Center for Health Care Delivery Science, Dartmouth College, Hanover, NH Medical Research: What are the main findings of the study? Naslund: In this study we explored whether people with severe mental illness such as schizophrenia, schizoaffective disorder, or bipolar disorder, use a popular social media website like YouTube to naturally provide and receive peer support. We found that people with severe mental illness use YouTube to feel less alone and to find hope, to support and to defend each other, and to share personal stories and strategies for coping with day-to-day challenges.   Dr. Grande: They also sought to learn from the experiences of others about using medications and seeking mental health care.  YouTube appears to serve as a platform that helps these individuals to overcome fears associated with living with mental illness, and it also creates a sense of community among them.

MedicalResearch.com Interview with: Prof I. Jolanda M. de Vries Professor, Dept of Tumor Immunology Radboud University Nijmegen Medical Research: What are the main findings of the study? Prof. de Vries: Dendritic cells are antigen-presenting cells with the unique capacity to activate naive antigen-specific T cells, and by this means are very suitable to induce immunologic antitumor responses. Dendritic cells cultured from monocytes can be matured and loaded with tumor antigen ex vivo and administered back into the patient. Within the lymph node, dendritic cells present antigens to T cells to initiate an immune response. Metastatic uveal melanoma patients were vaccinated with autologous DCs loaded with tumor antigens (gp100 and tyrosinase), obtained by leukapheresis, according to a schedule of 3 biweekly vaccinations. One to 2 weeks after the last vaccination, a skin test was performed to analyse the induction of immunologic responses. We can conclude that dendritic cell vaccination is feasible and safe in metastatic uveal melanoma. Dendritic cell-based immunotherapy is potent to enhance the host’s antitumor immunity against uveal melanoma in approximately one third of patients. (more…)

Steven J. Frank, M.D. Associate Professor of Radiation Oncology Medical Director of the Proton Therapy Center The University of Texas MD Anderson Cancer CenterMedicalResearch.com Interview with: Steven J. Frank, M.D. Associate Professor of Radiation Oncology Medical Director of the Proton Therapy Center The University of Texas MD Anderson Cancer Center MedicalResearch.com Editor’s Note: A recent research published in Oncology Payers, discusses the quality of life benefits and cost-savings of intensity modulated proton therapy (IMPT or proton therapy) with traditional x-ray therapy for advanced stage head and neck cancer. The senior author of the paper, Dr. Steven Frank, highlights two oropharyngeal cancer patients, one of whom received proton therapy and the other x-ray treatments. Both patients received chemotherapy. The study showed that although the upfront costs of proton therapy were three times that of standard x-ray treatments, the proton therapy patient was spared the necessity of a feeding tube, nutritional and supportive care and weight loss that accompanied the x-ray treatments. By the end of the treatment period, the total care costs for the proton therapy patient were 20% lower than the x-ray treatment plan. To evaluate the costs, Dr. Frank has been employing a costing tool used elsewhere at MD Anderson called Time-driven Activity-based Costing that places the emphasis on the value of medical care, both monetary and in terms of quality of life. Dr. Frank plans to enroll 360 patients over the next five years as well as to open the study to other cancer centers. He notes that the results will be especially valuable as health insurance companies look to further bundled insurance payments. Dr. Frank was kind enough to answer several questions regarding his work for the MedicalResearch.com audience. Medical Research: From a patient's perspective, what are the main differences between traditional x-ray therapy and proton therapy for cancer treatment? Dr. Frank: In proton therapy, the radiation hits the cancer, while with traditional x-ray the radiation hits the cancer and the normal tissues in the head and neck, causing more side effects during and after treatment. The main advantage is that proton therapy eliminates unnecessary radiation. As radiation oncologists, our primary goal is to effectively kill cancer while sparing the patient the side effects of excessive radiation. Proton therapy achieves this for many patients with a variety of cancers, including lymphoma, lung, head and neck, prostate, esophageal and pediatric cancers. (more…)
