Srinivasa Subramaniam, Ph.D., Assistant Professor Department of Neuroscience The Scripps Research Institute Jupiter, Florida 33458MedicalResearch.com Interview with: Srinivasa Subramaniam, Ph.D., Assistant Professor Department of Neuroscience The Scripps Research Institute Jupiter, Florida 33458   Medical Research: What is the background for this study? What are the main findings? Dr.  Subramaniam: Huntington’s disease (HD) is a genetic disorder occurs due to a mutation in a protein called huntingtin (mHtt), which affects 5-10 people per 100000 populations worldwide. Our research revolves around the question— why mutant huntingtin despite its ubiquitous expression through out the body selectively affects brain regions such as striatum, a region that regulates voluntary movement. We now found that mHtt activates a protein kinase complex, mammalian target of rapamycin complex 1 (mTORC1), which is required for normal functions such as translation of genes into proteins and also organelle recycling. We found the mTORC1 activation is so robust and sustained in the striatum that lead to the severe motor disabilities and premature death of HD mice. Our study indicates a functional relationship between huntingtin and mTOR the developmentally important genes with implication in Huntington’s disease pathogenesis. (more…)

MedicalResearch.com Interview with: Dr. med. Rainer Erices Institut für Geschichte und Ethik der MedizinMedicalResearch.com Interview with: Dr. med. Rainer Erices Institut für Geschichte und Ethik der Medizin Medical Research: What are the main findings of the study? Dr. Erices: The study presents the results of a first systematic investigation of clinical drug trials carried out by Western pharmaceutical firms in Eastern Germany in the 1980s. The scientific investigation of the East German Health system has only just started. The study shows that in that period of time, around 220 clinical trials were carried out. We now know how many patients took part and what remuneration the GDR received. It continues to be difficult to evaluate these tests. Despite intensive research efforts in different archives, we have been unable to find documentation on how detailed (and systematically) patients were informed about the trial they were taking part in. The responsible institutions repeatedly advised testers to stick to the law during the clinical trials. The law required that these trials should only be carried out on patients which had given their informed consent and had decided to participate voluntarily. However, so far there is no convincing proof that these legal requests were met. (more…)

Kevin L Thomas, MD Assistant Professor of Medicine Division of Clinical Cardiac Electrophysiology Duke Clinical Research InstituteMedicalResearch.com Interview with: Kevin L Thomas, MD Assistant Professor of Medicine Division of Clinical Cardiac Electrophysiology Duke Clinical Research Institute   Medical Research: What are the main findings of the study? Dr. Thomas: The number of participants with controlled blood pressure (readings of less than 140/90) increased by 12 percent in the six months between the first and last readings. Mean systolic blood pressure for the population decrease by 4.7mmHg. The number of participants who had high blood pressure in the range of 140-149/90-99 decreased systolic blood pressure by a mean of  8.8mmHg and those with readings in the higher range of 150/100 or above decreased systolic blood pressure by 23.7percent. The study concluded that a program that followed this type of approach was associated with improved blood pressures across a diverse  high-risk community.” (more…)

Dr. Tang: A chemical byproduct of gut bacteria-dependent digestion, TMAO (trimethylamine N-oxide), was previously shown to contribute to heart disease development. In this study, blood levels of TMAO for the first time are linked to heart failure development and mortality risk. (more…)
Author Interviews, General Medicine, Health Care Systems, Johns Hopkins / 29.10.2014

MedicalResearch.com Interview with: Eric Wan BS and Miceile Barrett BS Johns Hopkins University School of Medicine Baltimore, MD Medical Research: What is the background for this study? What are the main findings? Answer: Access to surgery is limited in resource-poor settings and low-and-middle income countries (LMICs) due to a lack of human and material resources. In contrast, academic hospitals in high-income countries often generate significant amounts of unused and clean medical supplies that cannot be re-used in the operating rooms of high-income countries. Programs such as Supporting Hospitals Abroad with Resources and Equipment (SHARE) provide an avenue for recovery of these supplies and donation to resource-poor hospitals in LMICs. From data collected from SHARE supplies donated by Johns Hopkins, we found that the nationwide impact for these programs to be $15.4 million among US academic hospitals, which accounts for only 19 categories of commonly recovered supplies. When we tracked our donated supplies to hospitals in Ecuador serving the poor, we found that the cost-effectiveness of these donations was US $2.14 per disability-adjusted life-year prevented.

Author Interviews, Depression, Gender Differences, NIH / 27.10.2014

Dr. Sunni Mumford PhD Earl Stadtman Investigator in the DESPR Epidemiology Branch Eunice Kennedy Shriver National Institute of Health and Human DevelopmentMedicalResearch.com Interview with: Dr. Sunni Mumford PhD Earl Stadtman Investigator in the DESPR Epidemiology Branch Eunice Kennedy Shriver National Institute of Health and Human Development Medical Research: What are the main findings of the study? Dr. Mumford: Depressive symptoms in healthy women who don’t have diagnosed clinical depression isn’t related to reproductive hormone levels, like estrogen, or impaired ovulation. Medical Research: What was most surprising about the results? Dr. Mumford: Earlier research indicates that changes in estrogen may be associated with depression, for instance during the menopausal transition. Our study identified significant associations between estrogen and depressive symptoms in models that didn’t account for confounding factors, but this relationship was completed eliminated when adjustments were made for common confounding factors like age, race, BMI, and also stress level in these premenopausal women. Another interesting finding was that a score describing mood-related menstrual symptoms indicated that such symptoms are highest in the premenstrual phase, but remain lower throughout the rest of women’s cycles. This tells us that altered mood symptoms are most frequent prior to menstruation. (more…)

Barbara J. Drew, RN, PhD, FAAN, FAHA David Mortara Distinguished Professor in Physiological Nursing Research Clinical Professor of Medicine, Cardiology University of California, San Francisco (UCSF) Department of Physiological Nursing San Francisco, CA 94143-0610 MedicalResearch.com: Interview Barbara J. Drew, RN, PhD, FAAN, FAHA David Mortara Distinguished Professor in Physiological Nursing Research, Clinical Professor of Medicine, Cardiology University of California, San Francisco (UCSF) Department of Physiological Nursing San Francisco, CA 94143-0610 Medical Research: What is the background for this study? Dr. Drew: Physiologic monitors used in hospital intensive care units (ICUs) are plagued with alarms that create a cacophony of sounds and visual alerts causing “alarm fatigue.” Alarm fatigue occurs when clinicians are desensitized by numerous alarms, many of which are false or clinically irrelevant. As a result, the cacophony of alarm sounds becomes “background noise” that is perceived as the normal working environment in the ICU. Importantly, alarms may be silenced at the central station without checking the patient or permanently disabled by clinicians who find the constant audible or textual messages bothersome. Disabling alarms creates an unsafe patient environment because a life-threatening event may be missed in this milieu of sensory overload. To date, there has not been a comprehensive investigation of the frequency, types, and accuracy of physiologic monitor alarms collected in a “real-world” ICU setting. For this reason, nurse and engineer scientists in the ECG Monitoring Research Laboratory at the University of California, San Francisco (UCSF) designed a study to provide complete data on monitor alarms.

Dr. Matthew Budoff, M.D. Los Angeles Biomedical Research Institute Torrance CaliforniaMedicalResearch.com Interview with: Dr. Matthew Budoff, M.D. Los Angeles Biomedical Research Institute Torrance California Medical Research: What are the main findings of the study? Dr. Budoff: We evaluated whether patients undergoing coronary CT angiography (non-invasive angiography) had better outcomes than those treated without the test.  We found survival was better with CT angiography.    Finding atherosclerosis allows cardiologists and primary care doctors to treat the patient better, including more statin therapy, more anti-platelet therapy, more lifestyle modifications.  Several small studies showed similar results, but this was by far the most significant and largest study of it’s kind.

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.

MedicalResearch.com Interview with: Joanna-Grace M. Manzano, MD Assistant Professor Department of General Internal Medicine Maria E. 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…)

David L. Katz, MD, MPH, FACPM, FACP Director, Yale University Prevention Research Center Griffin HospitalMedicalResearch.com Interview with: David L. 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.

Author Interviews, Dartmouth, Mental Health Research / 18.10.2014

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.

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…)

Zion Cancer Research Bldg. San Francisco, CA 94143-0808 Medical Research: What are the main findings of the study? Dr. Sanlorenzo: In the treatment of BRAF mutant melanoma, the combination of BRAF inhibitor and MEK inhibitor has a better cutaneous safety profile compared with BRAF inhibitor monotherapy. Combination regimen shows fewer cutaneous adverse events and longer cutaneous adverse event-free interval. In particular, the development of squamous cell carcinoma or keratoacanthoma was significantly less frequent. (more…)

Daniel A. Waxman, MD, PhD Department of Emergency Medicine David Geffen School of Medicine University of California, Los Angeles RAND Corporation Santa Monica, CaliforniaMedicalResearch.com Interview with: Daniel A. Waxman, MD, PhD Department of Emergency Medicine David Geffen School of Medicine University of California, Los Angeles RAND Corporation Santa Monica, California Medical Research: What are the main findings of the study? Dr. Waxman: About 10 years ago, three states (Texas, Georgia, and South Carolina) passed laws which made it much harder for doctors to be sued for malpractice related to emergency room care.   The goal of our research was to determine whether the lower risk of being sued translated into less costly care by emergency physicians.  To figure this out, we looked at the billing records of nearly 4 million Medicare patients and compared care before and after the laws took effect, and between states that passed reform and neighboring states that didn’t change their laws.   We found that these substantial legal protections didn’t cause ER doctors to admit fewer patients to the hospital, to order fewer CT or MRI scans, or to spend less for the overall ER visit.

Craig A Umscheid, MD, MSCE, FACP Assistant Professor of Medicine and Epidemiology Director, Center for Evidence-based Practice Medical Director, Clinical Decision Support Chair, Department of Medicine Quality Committee Senior Associate Director, ECRI-Penn AHRQ Evidence-based Practice Center University of Pennsylvania, Philadelphia, PA 19104MedicalResearch.com Interview with: Craig A Umscheid, MD, MSCE, FACP Assistant Professor of Medicine and Epidemiology Director, Center for Evidence-based Practice Medical Director, Clinical Decision Support Chair, Department of Medicine Quality Committee Senior Associate Director, ECRI-Penn AHRQ Evidence-based Practice Center, University of Pennsylvania Philadelphia, PA 19104 Medical Research: What are the main findings of the study? Dr. Umscheid: We developed an automated early warning and response system for sepsis that has resulted in a marked increase in sepsis identification and care, transfer to the ICU, and an indication of fewer deaths due to sepsis. Sepsis is a potentially life-threatening complication of an infection; it can severely impair the body’s organs, causing them to fail. There are as many as three million cases of severe sepsis and 750,000 resulting deaths in the United States annually. Early detection and treatment, typically with antibiotics and intravenous fluids, is critical for survival. The Penn prediction tool, dubbed the “sepsis sniffer,” uses laboratory and vital-sign data (such as body temperature, heart rate, and blood pressure) in the electronic health record of hospital inpatients to identify those at risk for sepsis. When certain data thresholds are detected, the system automatically sends an electronic communication to physicians, nurses, and other members of a rapid response team who quickly perform a bedside evaluation and take action to stabilize or transfer the patient to the intensive care unit if warranted. We developed the prediction tool using 4,575 patients admitted to the University of Pennsylvania Health System (UPHS) in October 2011.  We then validated the tool during a pre-implementation period from June to September 2012, when data on admitted patients was evaluated and alerts triggered in a database, but no notifications were sent to providers on the ground.  Outcomes in that control period were then compared to a post-implementation period from June to September 2013.  The total number of patients included in the pre and post periods was 31,093.

F.E. (Erica) Witkamp RN MSc Senior lecturer University of Applied Sciences Erasmus MC and Erasmus MC Cancer Institute Rotterdam, The Netherlands.MedicalResearch.com Interview with: F.E. (Erica) Witkamp RN MSc Senior lecturer University of Applied Sciences Erasmus MC and Erasmus MC Cancer Institute Rotterdam, The Netherlands. Medical Research: What are the main findings of the study? Response: We investigated the experiences of 249 bereaved relatives (response 51%) of patients who had died in the hospital, after a hospitalization of at least six hours. The main outcome measure was their global score of the quality of dying (QOD) on a 0-10 scale, with zero being “very poor” and ten “almost perfect”. Further, we assessed multiple experiences in the last days of life, such as symptom burden, preparedness for life closure, awareness of impending death, and care in the last days of life. We analyzed which of these factors was related to the quality of dying score, and subsequently whether the related factors represented specific domains of the dying phase. Relatives rated the overall score of QOD on average at 6.3 (sd 2.7) with a range from 0-10. During the last day(s) of life, 26% of the patients, and 49% of the relatives had been fully aware of imminent death. In the end 39% of the patients and 50% of the relatives had said goodbye; 77% of the patients had died in the presence of a relative. According to relatives patients had suffered moderately to severely from on average 7 out of 22 symptoms. In 53% relatives reported that in the last 24 hours symptoms had sufficiently been alleviated; efforts to control symptoms had been sufficient in 75%. In 64% relatives had been informed by the physician about the imminence of death, and in 70% they were satisfied about their involvement in decision making. In 55% relatives had experienced sufficient attention to individual preferences and wishes, and in 70% hospital facilities had been sufficient. Patients had been sufficiently affirmed as a person in 63%. (more…)
Author Interviews, Diabetes, Imperial College, Nature / 15.10.2014

Dr. David Hodson PhD Faculty of Medicine, Department of Medicine Imperial College LondonMedicalResearch.com: Interview with: Dr. David Hodson PhD Faculty of Medicine, Department of Medicine Imperial College London Medical Research: What is the background for this research? Dr. Hodson: Type 2 diabetes represents a huge socioeconomic challenge. As well as causing significant morbidity due to chronically elevated glucose levels, this disease is also a drain on healthcare budgets (~$20billion in the UK per year). While current treatments are effective, they are sometimes associated with side effects, usually due to off-target actions on organs such as the heart and brain. In addition, the ability to regulate blood glucose levels more tightly may decrease complications stemming from type diabetes (e.g. nerve, kidney and retina damage). As a proof-of-principle that the spatiotemporal precision of light can be harnessed to finely guide and control drug activity, we therefore decided to produce a light-activated anti-diabetic. (more…)

Michael S. Calderwood, MD MPH Department of Population Medicine Harvard Medical School and Harvard Pilgrim Health Care Institute Boston, MAMedicalResearch.com Interview with: Michael S. Calderwood, MD MPH Division of Infectious Diseases Brigham and Women's Hospital Boston, MA Medical Research: What are the main findings of the study? Dr. Calderwood: "In our study, we found that the risk of surgical site infection (SSI) following total hip arthroplasty and coronary artery bypass graft (CABG) surgery is higher for Medicare patients undergoing surgery in U.S. hospitals with lower surgical volume. This suggests that volume leads to experience, and experience leads to improved outcomes." "We found a significantly higher risk of surgical site infection in U.S. hospitals performing <100 total hip arthroplasty procedures and <50 CABG procedures per year on Medicare patients. In the lowest volume hospitals, 1 out of 3 infections following total hip arthroplasty and 1 out of 4 infections following CABG were in excess of expected outcomes based on experience in the highest volume hospitals."

David Polsky, MD, PhD Alfred W. Kopf, MD, professor of Dermatologic Oncology Ronald O. Perelman Department of Dermatology NYU Langone Medical CenterMedicalResearch.com Interview with: David Polsky, MD, PhD Alfred W. Kopf, MD, professor of Dermatologic Oncology Ronald O. Perelman Department of Dermatology NYU Langone Medical Center Medical Research: What are the main findings of the study? Dr. Polsky: We utilized a multi-disciplinary approach including an analysis of socioeconomic factors to elucidate the evolution of attitudes and behaviors maximizing personal ultraviolet light exposure during the 20th century in the United States.  We then compared melanoma incidence rates from national cancer registries to estimated skin exposure and found that they rose in parallel. Though causation cannot be made in an analysis such as this one, this paper describes a historical context for the changing attitudes promoting increased UV exposure, and the rising incidence of melanoma throughout the past century.  It also provides a framework in which to consider public health and education measures that may ultimately help reverse melanoma incidence trends.
