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.

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…)

Terrence Loftus, MD, MBA, FACS Medical Director, Surgical Service & Clinical Resources Banner Health Phoenix, Arizona 85006Medical Research.com Interview with: Terrence Loftus, MD, MBA, FACS Medical Director, Surgical Service & Clinical Resources Banner Health Phoenix, Arizona 85006 Medical Research: What are the main findings of the study? Dr. Loftus: This study demonstrated that a standardized safe surgery program effectively and systematically implemented across a diverse healthcare system resulted in a significant reduction in serious reportable events (SREs), thereby improving the quality of patient care and leading to significant cost avoidance.   For the purposes of the study, SREs were defined as any reported retained surgical item, wrong site, wrong patient or wrong procedure event. Following implementation of the Safe Surgery Program there was a 52% reduction in the SRE rate in the operating rooms and L&D areas in our system. The most dramatic change and greatest area of improvement was in wrong site events which demonstrated a 70% reduction for this type of serious reportable events. This was achieved through a Safe Surgery Program which consisted of three main components.
  • The first component was patient focused procedures. These are steps designed to prevent wrong site, wrong patient or wrong procedure events.
  • The second component was sponge, sharp and instrument count procedures. These are steps designed to prevent retained surgical items.
  • The final component was monthly observational audits that were performed to assess program compliance. (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.

Professor Robert Insall CR-UK Beatson Institute for Cancer Research Glasgow UKMedicalResearch.com Interview with: Professor Robert Insall CR-UK Beatson Institute for Cancer Research Glasgow UK Medical Research: What are the main findings of the study? Prof. Insall: The principal message is that melanoma cells make their own steering signals, and thus drive themselves out of the tumour and into the bloodstream.  This comes in two parts: (a) The principal steering signal when we assay melanoma spread in vitro is lysophosphatidic acid, LPA.  LPA steers cells with really remarkable accuracy; blocking LPA receptors stops them from spreading without hurting their health or ability to move. (b) Where does the LPA gradient come from?  They make it themselves.  There seems to be lots of LPA around; they break down the LPA near them, leading to a gradient that's low near the cells and high further away.  This is the gradient that steers the tumour cells.

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.

Dr. Bock: This study examined the association between dietary antioxidant micronutrients and risk of renal cell carcinoma (RCC) among a cohort of 96,196 postmenopausal women from the Women’s Health Initiative (WHI). During follow-up (median follow-up time was 12 years), there were 240 cases of confirmed renal cell carcinoma in the cohort. Dietary lycopene intake, measured at  baseline, was associated with a decreased risk of renal cell carcinoma (RCC). Women with the highest quartile of lycopene intake (>6427.7 mcg/day) had approximately 40% lower risk of RCC compared to those women in the lowest quartile of lycopene intake (<2727.6 mcg/day). There were no statistically significant associations observed between intake of beta-carotene, alpha-carotene, beta-cryptoxanthin, lutein + xeazanthin, vitamin C, or vitamin E and renal cell carcinoma.

Andre Kalil, M.D., M.P.H. Professor of Medicine Director, Transplant ID Program University of Nebraska Nebraska Medical Center Omaha, NE 68198-5400MedicalResearch.com Interview with: Andre Kalil, M.D., M.P.H. Professor of Medicine Director, Transplant ID Program University of Nebraska Nebraska Medical Center Omaha, NE 68198-5400 Medical Research: What are the main findings of the study? Dr. Kalil: In recent years, physicians treating staph infections with vancomycin have seen an increase in the minimum inhibitory concentration (MIC), the lowest concentration of an antimicrobial agent that inhibits the growth of a microorganism. This condition is referred to as vancomycin “MIC creep.” It is an indicator that the bacteria might be developing a reduced susceptibility to vancomycin. There also have been reports suggesting that elevations in vancomycin MIC values may be associated with increased treatment failure and death. To determine the effectiveness of vancomycin and other newer antibiotics used to treat Staphylococcus aureus, the UNMC team analyzed nearly 8,300 episodes of Staphylococcus aureus bloodstream infections from patients around the U.S. and in several other countries. The adjusted absolute risk of mortality among patients with Staphylococcus aureus bloodstream infections with high-vancomycin MIC was not statistically different from patients with Staphylococcus aureus bloodstream infections with low-vancomycin MIC.

MedicalResearch.com Interview with: Phil Tully PhD Early Career Research Fellow, Discipline of Medicine University of Adelaide Australia and Abteilung für Rehabilitationspsychologie und Psychotherapie Institut für Psychologie, Universität Freiburg Freiburg Germany Medical Research: What are the main findings of the study? Response: The systematic review indicated that anxiety disorders ascertained by clinical interview are highly prevalent in patients with verified coronary heart disease. Also, approximately 50% of anxiety disorders were comorbid with depression. There was however some uncertainty in prevalence estimates with high level heterogeneity observed between studies. It was also evident that studies measuring generalized anxiety disorder in outpatient samples reported an increased prognostic risk for major adverse cardiac events in the longer term, when adjusted for confounding factors, however there was limited data. There were no randomized controlled trials targeting anxiety disorders in this population. (more…)

MedicalResearch.com Interview with: Donna Tepper, M.D. Henry Ford Hospital Medical Research: What are the main findings of the study? Dr. Tepper: We looked at 94 patients who underwent bariatric surgery at Henry Ford from 2003 through 2013. Of those, 47 subsequently had body recontouring procedures, such as body lift, abdominoplasty (tummy tuck), arm lift, thigh lift, face lift.  We recorded the patients’ body mass index prior to bariatric surgery, and then again at 6 months, 1, 2.5, 4, and 5 years.  Of the patients who underwent contouring surgery, the average decrease in BMI was 18.24 at 2.5 years, compared to a statistically significant 12.45 at 2.5 years for those who did not have further surgery.  This is statistically significant.  This 3 point change in BMI is an 18-21 pound difference depending on patient height.  Furthermore, the BMI in the body contouring group continues to be lower at 4 and 5 years from bariatric surgery compared to the bariatric surgery alone group.

Dr. Cicognani: The study is part of a larger project of the Italian National Transplant Center (Centro Nazionale Trapianti, CNT), started in 2008, in collaboration with Istituto Superiore di Sanità, Centro Studi Isokinetic, University of Bologna, Cimurri Impresa e Sport and Patients’ associations. The general aim is to encourage transplant patients to practice physical activity and even sport activity, in view of its benefits in enhancing recovery and quality of life after transplantation. In this study we assessed Health-related quality of life on 118 active kidney transplant patients practicing different sports at low to moderate intensity and compared them with those of 79 sedentary kidney transplant patients and with 120 active healthy control subjects. Active transplant patients reported higher levels of quality of life than sedentary patients on most dimensions of quality of life and similar to active healthy controls. In brief, practicing sports may allow patients to achieve a level of quality of life similar to the general population of active individuals. (more…)

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…)

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…)

Rovira i Virgili University CIBERobn, Instituto Carlos III Medical Research: What are the main findings of the study? Response: In this large, multicenter, randomized clinical trial conducted in Mediterranean individuals at high cardiovascular risk, Mediterranean-diet supplemented with extra-virgin olive oil was associated to a lower increase in the prevalence of metabolic syndrome compared to the advice on a control low-fat diet. However, no beneficial effect of Mediterranean-diet on the incidence of metabolic syndrome among participants free of this condition at baseline was observed. Therefore, the lower increase in prevalence was especially due to the reversion of metabolic syndrome in those individuals with metabolic syndrome at baseline. (more…)

Assistant Professor - Cardiovascular Medicine Department of Internal Medicine University of Texas Health Science Center Houston TexasMedicalResearch.com Interview with Nils P. Johnson, M.D., M.S. Assistant Professor - Cardiovascular Medicine Department of Internal Medicine University of Texas Health Science Center Houston Texas Medical Research: What are the main findings of the study? Dr. Johnson: Our study had 3 main findings.
  • First, the numeric fractional flow reserve (FFR) value related continuously to risk, such that clinical events increased as FFR decreased and revascularization showed larger net benefit  for lower baseline FFR values.
  • Second, fractional flow reserve measured immediately after  stenting also showed an inverse relationship with prognosis, likely due to its relationship with diffuse disease.
  • Third, an fractional flow reserve-assisted strategy led to revascularization roughly half as often as an anatomy-based strategy, but with 20% fewer adverse events and 10% better angina relief. (more…)

Dr. Komej: Both atrial fibrillation (AF) and renal impairment are known to coexist and associated with increased morbidity and mortality. However, there is only limited data on changes of renal function after AF catheter ablation and predictors thereof. This is the largest study analyzing the effects of atrial fibrillation catheter ablation on renal function and changes thereof in a contemporary population during mid-term follow-up. We found that lower baseline eGFR was associated with higher CHADS2 and CHA2DS2-VASc scores and that both scores were independently associated with eGFR changes after atrial fibrillation catheter ablation as were atrial fibrillation recurrences.

Dr. Spanier: Bisphenol A (BPA) is a chemical that is present in many consumer products (lining of canned foods, some plastics, some receipt paper, etc). We found that higher maternal Bisphenol A levels during pregnancy were associated with increased odds of persistent wheezing in children and a decrease in lung function at age four. Child BPA levels were not associated with these poor lung health outcomes. (more…)
