Anthony P. Kontos, Ph.D. Assistant Research Director UPMC Sports Medicine Concussion Program Associate Professor Department of Orthopaedic Surgery University of PittsburghMedicalResearch.com Interview with: Anthony P. Kontos, Ph.D. Assistant Research Director UPMC Sports Medicine Concussion Program Associate Professor Department of Orthopaedic Surgery University of Pittsburgh Medical Research: What are the main findings of the study? Dr. Kontos: Our new Vestibular/Ocular Motor Screening (VOMS) examination was able to accurately identify nearly 90% of patients with a concussion. In our study of 64 concussed patients approximately five days post-injury and 78 healthy control-group patients who were administered VOMS by trained clinicians, we also found that more than 60% of patients with a concussion reported symptoms or had impairment on the VOMS following their injury. The VOMS, which was developed in conjunction with an interdisciplinary team of experts, assesses five areas of the vestibular ocular system: smooth pursuits, saccades (rapid eye movement), horizontal vestibular ocular reflex (VOR), visual motion sensitivity (VMS), and near-point-of-convergence (NPC) distance.

John Blosnich, Ph.D., M.P.H., Post-doctoral fellow at the Center for Health Equity Research and Promotion Veterans Affairs Pittsburgh Healthcare System. MedicalResearch.com Interview with: John Blosnich, Ph.D., M.P.H., Post-doctoral fellow at the Center for Health Equity Research and Promotion Veterans Affairs Pittsburgh Healthcare System. Medical Research: What are the main findings of the study? Dr. Blosnich: I think there are two main findings from our study: First, since the beginning of the All-Volunteer U.S. military in 1973, there has been a shift in childhood experiences among men who have served in the military. Second, the childhood experiences of women who have served in the military have been largely similar across the Draft and All-Volunteer Eras. (more…)

MedicalResearch.com Interview with: Yuting Zhang, Ph.D. Associate professor Graduate School of Public Health Department of Health Policy and Management. University of Pittsburgh MedicalResearch: What are the main findings of the study? Dr. Zhang: Since 2006, the government has randomly assigned low-income enrollees to stand-alone Part D plans, based upon the region in which they live. If low-income Medicare Part D enrollees were assigned to the least expensive plan instead of a random plan, the government and beneficiaries could save more than $5 billion in the first year. (more…)

Yael Schenker, MD, MAS Assistant Professor Division of General Internal Medicine Section of Palliative Care and Medical Ethics University of Pittsburgh Pittsburgh, PA 15213 MedicalResearch.com Interview with: Yael Schenker, MD, MAS Assistant Professor Division of General Internal Medicine Section of Palliative Care and Medical Ethics University of Pittsburgh Pittsburgh, PA  15213 MedicalResearch: What are the main findings of the study?  Dr. Schenker: We analyzed the content of cancer center advertisements placed in top TV and magazine media markets in 2012.  Out of 1427 advertisements that met our initial search criteria, we found 409 unique advertisements that promoted clinical services at 102 cancer centers across the country.  These advertisements promoted cancer treatments (88%) more often than cancer screening (18%) or supportive services (13%).  Provision of information about clinical services was scant. For example, 27% of advertisements mentioned a benefit of advertised services and 2% quantified these benefits.  2% mentioned a risk of advertised services and no advertisements quantified these risks.  5% mentioned costs or insurance coverage and no advertisements mentioned availability under specific insurance plans.  In contrast, use of emotional appeals was frequent (85%).  Emotional appeals commonly evoked hope for survival, focused on treatment advances, used fighting language, and/or evoked fear.  Nearly half of all advertisements included patient testimonials, overwhelmingly focused on stories about survival or cure.  Only 15% of testimonials included a disclaimer (for example, “most patients do not experience these results”) and none described the outcome that a typical patient may expect.

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 Invitation with: Timothy Hughes, PhD, MPH Roena B. 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 27157-1207Timothy Hughes, PhD, MPH Roena B. 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.

Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261MedicalResearch.com Interview with: Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261 MedicalResearch.com:  What are the main findings of the study? Dr. Teichert:  "Our study provided three main findings: First, we measured how long it takes subjects to allocate attention to a relevant target and how effectively they can block out the distractors. We found that after 120 msec selective attention is fully engaged and completely blocks out the distractor. Based on this finding, we predicted that subjects should be able to improve decision accuracy by delaying decision onset, and that this should be more effective than simply prolonging the whole decision process. Most importantly, we found that subjects indeed use this more effective way of improving decision onset: On average, subjects delayed decision onset by about 50 msec when we asked them be as accurate as possible. The good news is that people seem to use this more optimal mechanism automatically, without being told to do so and without being aware of what they do. The bad news is that we don’t seem to be using this skill quite as effectively as we could. In our case, subjects could have improved accuracy even further by delaying decision onset by an additional 50 ms. However, taken together, our findings show that decision onset is to some degree under cognitive control, and that we might be able to devise training strategies to harness its full potential” (more…)
Author Interviews, JAMA, Menopause, Sexual Health, University of Pittsburgh / 11.02.2014

MedicalResearch.com Interview with: Holly Thomas, MD General Internal Medicine Fellow, Women's Health and Clinical Research University of Pittsburgh Pittsburgh, PA 15213 MedicalResearch.com: What are the main findings of the study? Dr. Thomas: We found that, despite popular perception, the majority of women (85%) who are sexually active at midlife will remain sexually active four years later. We also found that the majority of women score low on a measure of sexual function. However, low sexual function scores did not mean women stopped having sex. In fact, the score on the sexual function measure did not predict whether women maintained sexual activity. Finally, we found that importance of sex was a strong predictor of whether women remained sexually active. Women who felt sex was moderately to extremely important in their lives were 3 times more likely to maintain sexual activity. (more…)

Janel Hanmer, MD, PhD University of Pittsburgh Medical Center Montefiore Hospital Pittsburgh, PA 15213MedicalResearch.com Interview with: Janel Hanmer, MD, PhD University of Pittsburgh Medical Center Montefiore Hospital Pittsburgh, PA 15213 MedicalResearch.com: What are the main findings of the study? Dr. Hanmer: We used the National Inpatient Sample - a sample of about 20% of US community hospitals with all discharges from those hospitals - to examine if insurance status is associated with transfer from one hospital to another. We were looking at patients who were already admitted to the hospital, not the patients who presented to the Emergency Department. We selected the five most common general medicine admissions for adults aged 18 to 64. We found that uninsured patients were less likely to be transferred than privately insured patients in four of the five conditions (about 20-40% less likely). We also found that women were less likely than men to be transferred in five of the conditions (about 35 to 40% less likely). (more…)
