MedicalResearch.com Interview with: Brian D. Glass Biological and Experimental Psychology, School of Biological and Chemical Sciences, Queen Mary, University of London, London, United Kingdom Bradley C. Love Department of Cognitive, Perceptual and Brain Sciences, University College London, London, United Kingdom MedicalResearch.com: What are the main findings of the study? Answer: We had 72 non-gaming participants play 40 hours of video games over 6 to 8 weeks. We tested them on psychological tests before and after. The participants either played The Sims (a life simulator game), or one of two versions of StarCraft (a real-time strategy game) -- one which had a higher level of complexity. We found that the StarCraft players (especially on the higher complexity version) performed better on specifically the psychological tasks which tested cognitive flexibility. Cognitive flexibility is the ability to adapt to a changing environment by keeping multiple things in mind and switch between tasks effectively. This sort of ability is considered a higher level psychological ability because it requires strategic thinking and creativity.

MedicalResearch.com Interview with: Xiaohui Zhuo PhD Health economist Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention MedicalResearch.com: What are the main findings of the study? First, someone diagnosed with type 2 diabetes may pay an average of about $85,500 treating the disease over his or her lifetime. Lifetime cost is higher for women, and for patients who developed the disease earlier in life. Second, treating diabetic complications account for more than half of lifetime costs, and a majority of which is attributed by damage to large blood vessels, which can lead to coronary heart disease and stroke.

Axel Bauer is head of the coronary care and chest pain unit and primary investigator in the research group of biosignal analysis and sudden death of the cardiology department of the Eberhard-Karls-Universität Tübingen, Germany.MedicalResearch.com Interview with: Dr. Axel Bauer, MD, FESC, F-ISHNE Prof. Dr. med. Axel Bauer is head of the coronary care and chest pain unit and primary investigator in the research group of biosignal analysis and sudden death of the cardiology department of the Eberhard-Karls-Universität Tübingen, Germany. MedicalResearch.com: What are the main findings of the study? Dr. Bauer: Catheter-based renal sympathetic denervation is a promising treatment option in patients with resistant arterial hypertension. However, it is invasive and might have presently unknown adverse side effects in the long-term. Therefore, identification of patients who benefit from RDN and, equally importantly, those who do not is of great importance.  With assessment of baroreflex sensitivity (BRS) we found a way to do that. Patients with resistant hypertension and impaired BRS at baseline benefited the most from RDN in terms of reduction of mean systolic BP on (ABPM) while RDN had no effect in patients with preserved BRS.

Bjarke Feenstra, Ph.D. Senior Research Scientist Statens Serum Institut Artillerivej 5, 2300 Copenhagen S DenmarkMedicalResearch.com Interview with: Bjarke Feenstra, Ph.D. Senior Research Scientist Statens Serum Institut Artillerivej 5, 2300 Copenhagen S Denmark MedicalResearch.com: What are the main findings of the study? Dr. Feenstra: We discovered a new genome-wide significant locus for infantile hypertrophic pyloric stenosis (IHPS) in a region on chromosome 11 harboring the apolipoprotein (APOA1/C3/A4/A5) gene cluster and also confirmed three previously reported loci. Characteristics of the new locus led us to propose the hypothesis that low levels of circulating lipids in infants are associated with increased risk of IHPS. We addressed this hypothesis by measuring plasma lipid levels in prospectively collected umbilical cord blood from a set of 46 IHPS cases and 189 matched controls. We found that levels were on average somewhat lower in the children who went on to develop the condition. (more…)

MedicalResearch.com Interview with: Ruifeng Cao, MD,PhD Postdoctoral Fellow Laboratory of Nahum Sonenberg McGill University Department of Biochemistry Montreal, QC H3A 1A3, Canada MedicalResearch.com: What are the main findings of the study? Answer: Circadian (~24h) timing is a fundamental biological process, underlying cellular physiology in animals, plants, fungi, and cyanobacteria.  In mammals, including humans, a circadian clock in the brain drives daily rhythms in sleep and wakefulness, feeding and metabolism, and many other essential processes. We studied how protein synthesis, which is a fundamental process underlying many biological activities, is controlled in the brain clock in mice and identified a protein that functions as a clock repressor. By removing the repressor protein, the clock function is improved. (more…)

Medical Research.com Interview with: Katrin Streckfuss-Boemeke, PhD Department of Cardiology and Pneumology Heart Research Center Göttingen (HRCG) University Medical Center Göttingen Georg-August-University Göttingen 37075 Göttingen Germany Medical ResearcH.com: What are the main findings of the study? Answer: The main finding is that human induced pluripotent stem cells (hiPSCs) can be generated from different somatic cell sources including bone marrow mesenchymal stem cells (MSCs), hair keratinocytes, and skin fibroblasts, but MSCs and fibroblasts are more easily reprogrammed than keratinocytes. All generated hiPSCs can differentiate into cardiomyocytes with an efficiency ranging from 3 to 42%. However, the highest cardiac differentiation efficiency was achieved from MSC-derived hiPSCs. Although the cardiac differentiation efficiency varied among different cell lines, there is no significant difference in the functionalities of cardiomyocytes derived from different hiPSC lines.

MedicalResearch.com:  Interview with: Therese Koops Grønborg PhD student/ph.d.-studerende, MSc Section of Biostatistics/Sektion for Biostatistisk Department of Public Health/Institut for Folkesundhed Aarhus University Bartholins Allé 2, DK-8000 Aarhus C, Denmark MedicalResearch.com: What are the main findings of the study? Answer: There are three important findings in our study. We estimated a population-based Autism Spectrum Disorder (ASD) sibling recurrence risk relative to the background population and found an almost seven-fold increase. While this indeed is an increased risk, it is also lower than what other recent studies have suggested. We also compared the relative recurrence risk for full and maternal/paternal half siblings and found a lower relative recurrence risk in half siblings than in full siblings, which supports the genetic pathway to ASD. The recurrence risk for maternal half siblings is still higher than for the background population suggesting that factors unique to the mother, such as the intrauterine environment and perinatal history, may contribute to ASD. Last, but not least, we estimated the time trends in the relative recurrence risk. While the ASD prevalence has been increasing for several years, we found no time trends in the relative recurrence risk, suggesting that the factors contributing to the risk for ASDs recurrence in siblings (perhaps a combination of genes and environment) have not changed over time.

The Fred Hatch Professor of Medicine Director, Clinical Outcomes and Clinical Trials Program in Nephrology University of Tennessee Health Science Center Chief of Nephrology Division of Nephrology, Memphis VA Medical Center MedicalResearch.com: What are the main findings of the study? Dr. Kovesdy: In this study of >650,000 US veterans with CKD we found that categories of lower SBP/DBP combinations are associated with lower mortality only as long as the DBP component remains above a threshold of approximately 70 mmHg, and that patients with BP values in the range of 130-159/70-89 mmHg had the lowest mortality.  Patients who might be considered to have “ideal” blood pressure (<130/80) actually had increased mortality due to the inclusion of individuals with low systolic and diastolic blood pressures.

Leora I. Horwitz, MD, MHS Section of General Internal Medicine, Department of Medicine, Yale School of Medicine, Center for Outcomes Research and Evaluation, Yale–New Haven Hospital, New Haven, ConnecticutMedicalResearch.com Interview with: Leora I. Horwitz, MD, MHS Section of General Internal Medicine, Department of Medicine, Yale School of Medicine, Center for Outcomes Research and Evaluation, Yale–New Haven Hospital, New Haven, Connecticut MedicalResearch.com: What are the main findings of the study? Answer: We interviewed nearly 400 older patients who had been admitted with heart failure, pneumonia or heart attack within one week of going home from the hospital. We also reviewed the medical records of 377 of the patients. We found, for example, that:
  • 40% of patients could not understand or explain the reason they were in the hospital in the first place;
  • A fourth of discharge instructions were written in medical jargon that a patient was not likely to understand;
  • Only a third of patients were discharged with scheduled follow-up with a primary care physician or cardiology specialist;
  • Only 44% accurately recalled details of their appointments.
In other words, we didn't do a very good job of preparing patients for discharge, and perhaps as a result, patients were pretty confused about important things they needed to know after they were home. We just published a companion paper in the Journal of Hospital Medicine last week in which we looked at the discharge summaries for the same patients - that is, the summary of the hospitalization that is meant to help the outpatient doctor understand what happened in the hospital. Turns out we were just as bad at communicating with doctors as with patients - we focused on details of the hospitalization rather than what needed to happen next or what needed to be followed up, and in a third of cases, we didn't even send the summary to the outpatient doctor. In fact out of 377 discharge summaries, we didn't find a single one that was done on the day of discharge, sent to the outpatient doctor, and included all key content recommended by major specialty societies.

Dr. Finlay McAlister Division of General Internal Medicine Patient Health Outcomes Research and Clinical Effectiveness Unit University of Ottawa, Ottawa Hospital Research Institute, Ottawa, Ont.MedicalResearch.com Interview with: Dr. Finlay McAlister Division of General Internal Medicine Patient Health Outcomes Research and Clinical Effectiveness Unit University of Ottawa, Ottawa Hospital Research Institute, Ottawa, Ont. MedicalResearch.com: What are the main findings of the study? Answer: Heart Failure carries a high risk of readmission/death in the first 30 days after hospital discharge (approximately 20%) - even in this cohort of patients with first time diagnosis of heart failure who were discharged home to the community.  Patients who do not have an outpatient physician follow-up visit in the first 30 days after discharge have poorer outcomes at 30 days, 3 months, 6 months, and 12 months.  Although outcomes are similar for patients who see an unfamiliar or a familiar physician in that first 30 days, over the longer term follow-up with a familiar physician is associated with better outcomes than follow-up with unfamiliar physician(s).

MedicalResearch.com Interview with: John P. Cooke MD PhD Chair, Department of Cardiovascular Sciences Director, Center for Cardiovascular Regeneration Houston Methodist Research Institute 6670 Bertner St MS: R6-414, Houston, TX 77030John P. Cooke MD PhD Chair, Department of Cardiovascular Sciences Director, Center for Cardiovascular Regeneration Houston Methodist Research Institute 6670 Bertner St MS:  R6-414, Houston, TX 77030   MedicalResearch.com: What are the main findings of the study? Answer: We discovered that the proton pump inhibitors PPIs), as a class, impair vascular relaxation.  The PPIs have this effect by suppressing the activity of a key enzyme required for cardiovascular health. The enzyme is known as DDAH (for dimethylarginine dimethylaminohydrolase).  This enzyme is critical in clearing ADMA (asymmetric dimethylarginine) from tissues and the circulation.  Because ADMA is an endogenous inhibitor of nitric oxide synthase, accumulation of ADMA impairs vascular relaxation and vascular homeostasis.   Previously, we and others have found that, by inhibiting endothelium-derived nitric oxide, ADMA accelerates vascular disease in preclinical models.  In humans, ADMA is linked to the severity of vascular disease, and is an independent risk factor for major adverse cardiovascular events (MACE).  Thus, the effect of PPIs to inhibit DDAH would be anticipated to impair cardiovascular health, and to increase the risk of MACE.

MedicalResearch.com: Orly Vardeny, PharmD, MS Associate Professor of Pharmacy and Medicine University of Wisconsin-Madison MedicalResearch.com What are the main findings of the study? Answer: We performed a post-hoc analysis of the RALES study to assess rates of hyperkalemia and hypokalemia among African American (AA) and non-AA study participants, and examined clinical outcomes by race. We found that AA had less overall increases in potassium compared to non-AA, and exhibited less hyperkalemia with spironolactone. AA subjects were also found to have higher rates of hypokalemia, even among those randomized to spironolactone. Moreover, AA participants appeared to derive less clinical benefit from spironolactone. While non-AA demonstrated reduced risk for death and the combined endpoint of death or heart failure hospitalizations when randomized to spironolactone, African Americans did not derive benefit, and the risk of these outcomes were not different between spironolactone and placebo among AA.

Alzheimer's - Dementia, Author Interviews, Genetic Research, Mental Health Research / 16.08.2013

MedicalResearch.com Interview with: Dr. Ramon Trullas Research Professor CSIC Institute of Biomedical Research of Barcelona MedicalResearch.com: What are the main findings of the study? Answer: The findings reported in this manuscript that we consider can be underscored are: 1) Asymptomatic subjects at risk of developing sporadic Alzheimer’s disease (AD), as well as symptomatic patients diagnosed with probable sporadic AD show a low concentration of circulating cell free mitochondrial DNA (mtDNA) in cerebrospinal fluid (CSF). 2) Pre-symptomatic subjects carrying pathogenic PSEN1 gene mutations which cause early onset familial AD, also exhibit low mtDNA content in CSF. 3) Reduced mtDNA content in CSF occurs in preclinical PSEN1 mutation carriers at least one decade before patients are expected to manifest clinical signs of dementia and well before any alteration in currently known AD biomarkers. 4)  Low mtDNA content in CSF distinguishes patients diagnosed with AD from either controls or patients with fronto-temporal lobar degeneration. These findings indicate that the amount of circulating cell-free mtDNA content in CSF may be a novel biomarker for the early detection of AD in the preclinical stage of AD. Moreover, the observation that low mtDNA content in the CSF is associated with both sporadic and familial forms of AD suggests that, independently of the etiology, regulation of mtDNA content is a converging factor in the pathophysiology of AD.

MedicalResearch.com Interview with: Steve Estus PhD Dept. of Physiology University of Kentucky Office: Room 332 Sanders-Brown Building 800 S. Limestone Street Lexington, KY 40536-0230 MedicalResearch.com: What are the main findings of the study? Answer: We report evidence for the function of a Alzheimer's genetic  risk factor.  This protective allele of the polymorphism decreases the splicing efficiency of exon 2 in CD33, a receptor protein that regulates microglial activation.  Loss of exon 2 appears to produce a dormant CD33 protein, resulting in increased microglial phagocytosis activity.  Overall, these findings confirm and extend recent papers in Neuron and Nature Neuroscience  (discussed further in our report) that described decreased CD33 activity with the protective SNP allele.

MedicalResearch.com Interview with: Rakesh M. Suri MD, D.Phil. Mayo Clinic College of Medicine, Rochester, Minnesota MedicalResearch.com: What might clinicians “take home” from this study? Answers: a. The contemporary outcomes of surgical correction of mitral regurgitation are excellent based upon results observed in this large multinational, multi-institutional study, Mitral valve surgery now has a low peri-operative risk of death or complications, and a very high likelihood of saving a patient’s own heart valve (>90% - repair); thereby avoiding the need for replacement with an artificial valve substitute. b. All patients with severe degenerative mitral regurgitation are at risk for heart failure and/or death when surgical correction is delayed.  A safe period of “watchful waiting” in those with severe mitral regurgitation due to flail leaflets, even in the absence of traditional Class I triggers for surgery (symptoms or left ventricular dilation/dysfunction) does not exist. c. Prompt mitral valve surgery within months following the diagnosis of severe degenerative mitral regurgitation, even in those without symptoms, is associated with important and sustained long term benefits including a 40% decrease in death and 60% less heart failure risk, sustained many years following surgical intervention (more…)

MedicalResearch.com: What are the main findings of the study? Answer: A total of consecutive 1,075 patients undergoing abdominal laparoscopic surgery between 2005 and 2011, including 715 basic and 360 advanced laparoscopic surgeries, were reviewed. The perioperative management protocol consists of interruption of antiplatelet therapy (APT) one week before surgery and early postoperative re-institution in low thromboembolic risk patients (n=160, iAPT group), whereas preoperative APT was maintained in patients with high thromboembolic risk or emergent situation (n=52, cAPT group). Perioperative and outcome variables of cAPT and iAPT groups, including bleeding and thromboembolic complications, were compared to those of patients without APT (non-APT group, n=863).
  • No case suffering excessive intraoperative bleeding due to continuation of APT was observed. There were 10 postoperative bleeding complications (0.9%) and 3 thromboembolic events (0.3%), but surgery was free of both complications in cAPT group. No significant differences were found between the groups in operative blood loss, blood transfusion rate, and the occurrence of bleeding and thromboembolic complications.
  • Multivariable analyses showed that multiple antiplatelet agents (p=0.015) and intraoperative blood transfusion (p=0.046) were significant prognostic factors for postoperative bleeding complications.  Increased thromboembolic complications were independently associated with high New York Heart Association class (p=0.019) and history of cerebral infarction (p=0.048), but not associated with APT use.

MedicalResearch.com: What are the main findings of the study? Answer: Overall, diarrhoea occurred in just over 10% participants and diarrhoea caused by C. difficile in about 1%. These outcomes were equally common in those taking the microbial preparation and those taking placebo. Other outcomes (e.g. common GI symptoms, length of hospital stay, quality of life) were also much the same in the two groups. So, there was no evidence that the microbial preparation had prevented diarrhoea or had led to any other health benefit. In agreement with previous research, serious adverse events were also similar in the two groups – so we found no evidence that the microbial preparation caused any harm. (more…)
