Gregg C Fonarow, UCLA Medical Ctr, Los Angeles, CA; Director, Ahmanson-UCLA Cardiomyopathy Center Professor, Department of Medicine Associate Chief, Cardiology David Geffen School of MedicineMedicalResearch.com Interview with: Gregg C Fonarow, UCLA Medical Ctr, Los Angeles, CA; Director, Ahmanson-UCLA Cardiomyopathy Center Professor, Department of Medicine Associate Chief, Cardiology David Geffen School of Medicine MedicalResearch.com: What are the main findings of the study? Dr. Fonarow: The study examined data from hospitals that have adopted the American Heart Association/ American Stroke Association’s national quality initiative, Target: Stroke. The primary aim of Target: Stroke is to increase the number of stroke patients treated with tPA for acute ischemic stroke within 60 minutes or less after hospital arrival. The study demonstrated that patients received stroke therapy significantly faster in hospitals that participated in Target: Stroke. Between 2010 and 2013, the time between hospital arrival and use of tPA (door-to-needle time) dropped by 15 minutes, from 74 to 59 minutes, in hospitals that participated in Target: Stroke. This study found that the percentage of patients treated within the recommended timeframe increased from less than one-third before Target: Stroke to more than half afterwards. The Target: Stroke program goal of 50 percent or more of patients having door-to-needle times within 60 minutes was successfully achieved. Faster treatment was associated with improved patient outcomes and fewer complications, including death. (more…)
Author Interviews, Erasmus, JAMA, Stroke / 18.02.2014

dr_Arfan_IkramMedicalResearch.com Interview with: M. Arfan Ikram, MD, PhD Departments of Radiology, Epidemiology, and Neurology Erasmus Medical Center, Rotterdam, the Netherlands MedicalResearch.com:  What are the main findings of the study? Dr. Ikram: The main finding of the study, carried out within the Rotterdam Study and led by drs. Daniel Bos and Arfan Ikram (both from the Erasmus Medical Center Rotterdam, the Netherlands), was that intracranial atherosclerosis is a major risk factor for stroke in the Western (white) population. Traditionally, intracranial atherosclerosis has not been considered of major importance to stroke risk in Western populations. In contrast, most research on intracranial atherosclerosis originates from Asian and African populations, where is was actually recognized as the most important risk factor of stroke. Our study demonstrates that also in the Western population intracranial atherosclerosis is a major risk factor for stroke and should get more focus in clinical practice. Moreover, our findings indicate that its contribution to the proportion of all strokes is greater than that of atherosclerosis in other vessel beds that are further away from the brain. (more…)

Henry R. Kranzler, MD Professor, Department of Psychiatry Director of the Center for Studies of Addiction. University of Pennsylvania Perelman School of Medicine, PhiladelphiaMedicalResearch.com Interview with: Henry R. Kranzler, MD Professor, Department of Psychiatry Director of the Center for Studies of Addiction. University of Pennsylvania Perelman School of Medicine, Philadelphia MedicalResearch.com: What are the main findings of the study? Dr. Kranzler: The study had two main findings:
  • First, topiramate, at a maximal dosage of 200 mg/day, which is lower than the 300 mg/day used in prior treatment trials, substantially reduced the frequency of heavy drinking and increased the frequency of abstinent days more than placebo. The lower dosage was well tolerated.
  • Second, a variant in a gene that encodes a receptor subunit that binds topiramate moderated the response to topiramate. That is, C-allele homozygotes in the single nucleotide polymorphism rs2832407 in GRIK1, the gene encoding the GluK1 subunit of the kainate receptor, were the subgroup that accounted for the effects of topiramate on heavy drinking. This has important implications for the personalized treatment of alcohol use disorder, in that 40% of people of European ancestry have this genotype and, if confirmed, these findings would make it possible to screen people genetically to select an effective treatment.

Dr. Misha A. Rosenbach Assistant Professor of Dermatology Hospital of the University of Pennsylvania Section Editor, JAMA Dermatology Patient PageMedicalResearch.com Interview with: Dr. Misha A. Rosenbach Assistant Professor of Dermatology Hospital of the University of Pennsylvania Section Editor, JAMA Dermatology Patient Page MedicalResearch.com: What are the main findings of the study? Dr. Rosenbach: There is strong agreement between teledermatologists and in-person dermatologists when evaluating inpatients at a tertiary care academic hospital.  The primary aim of this study was to assess telederm as a triage tool.  Many dermatologists are not full-time hospitalists, but work in private practice or clinics which may be remote from affiliated hospitals.  The goal was to evaluate whether teledermatology could help those providers assess the acuity of inpatient consults.  There was strong concordance.

Author Interviews, Johns Hopkins, NEJM / 13.02.2014

MedicalResearch.com Interview with: Dr. Richard P. Allen Department of Neurology Johns Hopkins University Baltimore, MD 21224, MedicalResearch.com: What are the main findings of the study? Dr. Allen:  This study should serve to change medical practice by reducing use of pramipexole and ropinirole to avoid the insidious worsening of restless legs syndrome that occurs for many on these drugs. Pramipexole (Mirapex) a medication that mimics dopamine in the brain  in usual therapeutic doses for treatment of restless legs syndrome (RLS) works at first but over time one year makes the disease worse for up to 9% of the patients on 0.5 mg a day. Pregabalin (Lyrica) an anti-convulsant and pain drug  that works on a calcium channel in the brain in therapeutic dose for RLS (300 mg a day) does not make the disease worse  (There is some natural progression of the disease shown to occur fro 1 - 2% or patients over a year.. seen in this study). Pregabalin is in the short run as effective as pramipexole (over 12 weeks) and in the long run over 52 weeks more effective. These results confirm what had been expected that the dopamine drug pramipexole makes worse Restless Legs Syndrome while a drug not directly acting on the dopamine system does NOT make restless legs syndrome worse.

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…)

Hammond, MD, PhD, MPH Research Associate International Center for Spinal Cord Injury Hugo W. Moser Research Institute at Kennedy Krieger Institute Baltimore, MD 21205. MedicalResearch.com: What are the main findings of the study? Researchers: ·    Between 2007 and 2010, the number of serious traumatic spinal cord injuries (TSCI) in the United States (U.S.) increased, doing so more rapidly among older adults (age ≥65 years) compared to younger adults (age <65 years). Injuries from falls have overtaken motor vehicle crashes as the main cause of adult TSCI. ·    Older adults are more likely to experience worse outcomes compared to younger adults even after taking into account severity and mechanism of injury, as well as other co-morbid conditions. Older adults are 4 times more likely to die in the emergency room, and if admitted to inpatient care, they are 6 times more likely to die as inpatients compared to younger adults. ·    Emergency room charges for treatment of acute TSCI among adults increased 20% from $3,342 per encounter in 2007 to $4,024 per encounter in 2010 even after accounting for the cost of inflation.

Dr. Fenton: This was a cross-sectional study, and thus, a snapshot in time. Although it cannot infer cause or temporality of obesity and colon polyp risk in men, it does show that obese men were more likely to have a polyp than their lean counterpart. In addition, there were serum biomarkers also associated with this risk. This could eventually lead to future blood tests to identify individuals at greater risk for polyps and inform screening recommendations. (more…)

Roberto Fernández Galán, PhD Department of Neurosciences, School of Medicine Case Western Reserve University Cleveland, OH, USAMedicalResearch.com Interview with: Roberto Fernández Galán, PhD Department of Neurosciences, School of Medicine Case Western Reserve University Cleveland, OH, USA MedicalResearch.com: What are the main findings of the study? Dr. Galán: The main finding is that autistic brains create more information at rest than non-autistic brains. This is consistent with the classical view on autism as withdrawal into self. It is also consistent with a recent theory on autism, the “Intense World Theory”, which claims that autism results from hyper-functioning neural circuitry, leading to a state of excessive arousal. From both perspectives, the classical and the IWT, communication and social deficits associated with autism result from having a more intense inner life and a higher level of introspection. (more…)

Dr Ginsburg: This study examined the long-term outcomes of youth treated for an anxiety disorders. Findings revealed that almost half of anxious youth treated for an anxiety disorder were in remission (i.e., did not meet diagnostic criteria for any of the three study entry anxiety disorders) at an average of six years since starting treatment. Youth showing clinically meaningful improvement after 12 weeks of treatment, were more likely to be in remission, had lower anxiety severity, and had better functioning compared to youth who showed minimal or no initial clinical improvement. Treatment type did not affect long-term outcomes. (more…)

Answer: The study was able to illustrate the design and clinical testing of an MRI breast coil for combined MRI and Near Infrared Spectroscopy. The coil was tested on 8 healthy volunteers spanning all bra cup sizes and mammographic density categories. In the past, MRI/NIRS imaging was only possible in C and D cup sized breasts. The system also will give researchers the ability to target lesions in hard-to-reach areas close to the chest wall. With the successful completion of this study, simultaneous MRI/NIRS is possible in all breast sizes, tissue compositions, and lesion locations. (more…)

Answer: In our systematic review of all new drugs approved by the FDA over an 8 year period, we found that there was real variability in the quality and quantity of clinical trial evidence used as the basis of the agency’s approval decisions. Some drugs were studied in multiple randomized, double-blinded, controlled clinical trials that provide very helpful information for patients and physicians. However, other drugs were studied in clinical trials that did not produce as much information about their safety and effectiveness. (more…)

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…)

Answer: This study examined 2007-2012 commercialism trends in schools attended by nationally representative samples of US elementary and secondary students. While some measures showed significant decreases over time (especially beverage vending measures), most students at both elementary and secondary school levels continued to be exposed to school-based commercialism. Commercialism increased significantly with grade level. The most frequent type of commercialism varied by school level:  food coupons used as incentives was most common at the elementary school level, while exclusive beverage contracts were the most prevalent type of commercialism for middle and high school students.

Naama Barnea-Goraly M.D. Center for Interdisciplinary Brain Sciences Research Stanford UniversityMedicalResearch.com Interview with: Naama Barnea-Goraly M.D. Center for Interdisciplinary Brain Sciences Research Stanford University MedicalResearch.com: What are the main findings of the study? Answer: Our main findings showed that compared with age and sex matched controls, children with type 1 diabetes have significant differences in white matter structure in widespread brain regions. Within the type 1 diabetes group, earlier onset of diabetes and longer duration were associated with greater alterations in white matter structure. In addition, measures of hyperglycemia and glucose variability, but not hypoglycemia were associated with white matter structure; however, hypoglycemia exposure and the number of severe hypoglycemia events in our sample were too small to identify statistically meaningful differences. Finally, we observed a significant association between white matter structure and cognitive ability in children with type 1 diabetes, but not in controls. (more…)

Madhav Goyal MD, MPH Assistant Professor General Internal Medicine Johns Hopkins School of MedicineMedicalResearch.com Interview with: Madhav Goyal MD, MPH  Assistant Professor General Internal Medicine Johns Hopkins School of Medicine MedicalResearch.com: What are the main findings of the study? Dr. Goyal:
  • The evidence is moderately strong that there is a small but consistent benefit for mindfulness meditation programs to improve 3 symptoms: anxiety, depression, and pain.  We found low level evidence that mindfulness meditation helps with symptoms of stress and distress, as well as with the mental health dimension of quality of life.
  • For the symptoms of anxiety and depression for which we find moderate evidence of benefit, we need to keep in mind that most of the trials didn't study people with a clinical diagnosis of anxiety or depression (although a few did).  Most were studying diverse patient populations who may have had a low level of these symptoms, such as those with  breast cancer, fibromyalgia, organ transplant recipients, and caregivers of people with dementia.
  • We found about a 5-10% improvement in anxiety symptoms compared to placebo groups.  For depression, we found a roughly 10-20% improvement in depressive symptoms compared to the placebo groups. This is similar to the effects that other studies have found for the use of antidepressants in similar populations.
  • While we found that the evidence was moderately strong that mindfulness meditation programs may improve pain, there weren't as many trials evaluating chronic pain, and so we don't understand what kinds of pain this type of meditation may be most useful for.

Dr. Ferrario: A significant and unexpected difference in the hemodynamic mechanisms that account for the elevated blood pressure between untreated hypertensive men and women. The main findings were: "Despite there being no differences between women and men in terms of office blood pressure, heart rate and body mass index, men demonstrated lower values of pulse pressure, systemic vascular resistance, brachial artery pulse wave velocity and augmentation index. In each of the three hypertension categories, the increased blood pressure in men was associated with significant augmentations in stroke volume and cardiac output compared with women. Sex-related hemodynamic differences were associated in women with higher plasma levels of leptin, hs-CRP, plasma angiotensin II and serum aldosterone. In women but not men, hs-CRP correlated with plasma concentrations of transforming growth factor β1 (TGFβ1) and body weight; in addition, plasma TGFβ1 correlated with levels of serum vascular cell adhesion molecule 1."

Stewart C. Alexander, PhD Department of Medicine Duke University Medical Center Durham, North CarolinaMedicalResearch.com Interview with: Stewart C. Alexander, PhD Department of Medicine Duke University Medical Center Durham, North Carolina MedicalResearch.com: What are the main findings of the study? Dr. Alexander: Adolescents are reluctant to talk about sex with their doctors and won't raise the topic with their doctors. For physicians, there are common and valid barriers to talking about sexuality with adolescents, including time pressures and discomfort with the topic. Two-thirds of adolescents in our study had some sexuality talk during their annual visit, lasting 36 seconds long. Girls, African Americans, and older teens were more likely to receive sexuality talk. Additionally, longer visits and visits where the physician talked confidentially with their adolescent patient were more likely to have sexuality talk. Our study suggest that sexuality conversations in annual visits can be improved.

Dr. Jacques Donzé MD PhD Research Associate Division of General Internal Medicine and Primary Care, Brigham and Women’s Hospital Harvard Medical School, Boston, MA 02115, USADivision of General Internal Medicine, Bern University Hospital, 3010 Bern, SwitzerlandMedicalResearch.com Interview with: Dr. Jacques Donzé MD PhD Research Associate Division of General Internal Medicine and Primary Care, Brigham and Women’s Hospital Harvard Medical School, Boston, MA 02115, MedicalResearch.com: What are the main findings of the study? Dr. Donzé: In a large retrospective cohort study, we identified the primary diagnoses of 30-day potentially avoidable readmissions in medical patients according to the most common comorbidities. Interestingly, almost all of the top five diagnoses of potentially avoidable readmissions for each comorbidity were possible direct or indirect complications of that comorbidity. Patients with cancer, heart failure, and chronic kidney disease had a significantly higher risk of potentially avoidable readmission than those without those comorbidities. Also, when readmitted, patients with chronic kidney disease had a 20% higher risk of having the readmission be potentially avoidable. (more…)

Miller Chair in Age-Related Macular Degeneration Research Professor of Ophthalmology and Microbiology Vice Chair, Research (Department of Ophthalmology) Department of Ophthalmology, University of Texas Southwestern Medical Center Dallas, TX FN-γ Blocks CD4+CD25+ Tregs and Abolishes Immune Privilege of Minor Histocompatibility Mismatched Corneal Allografts MedicalResearch.com: What are the main findings of the study? Dr. Niederkorn: These findings indicate that a combination of two simple maneuvers increases the acceptance of corneal transplants. In the past, there was no clear benefit in performing tissue matching of the cornea donor’s major histocompatibility complex (MHC) with the recipient of the corneal transplant. However, our study in experimental animals revealed that blocking a single immune system molecule called interferon-gamma (IFN-γ) combined with matching the corneal transplant donor with the transplant recipient’s MHC gene complex reduced the risk of rejection to less than 10% in the total absence of anti-rejection drugs. This study revealed that blocking this single immune system molecule promoted the development of immune system cells called T regulatory cells (Tregs) that suppressed the lymphocytes that are responsible for attacking organ transplants.
