MedicalResearch.com Interview Invitation Dorna Jafari, M.D. and Michael J Stamos, MD Professor of Surgery John E. Connolly Chair, Department of Surgery University of California, Irvine Orange, CA 92868 MedicalResearch.com: What are the main findings of the study? Answer: Surgeons are faced with an aging population and data regarding outcomes is rare given that many studies preclude the elderly from the study population. Therefore, it is difficult to accurately discuss risk of surgical resection given the lack of data. Therefore we aimed to report the national trends and outcomes of colorectal cancer treatment in the elderly population. We demonstrated that the majority of resections are performed in patients >65yeras old. There is a trend towards a decrease in incidence of colorectal resection and a decrease in rate of mortality during 2001-2010.  However, the unique physiological changes associated with aging contribute to increase morbidity and morality as demonstrated by our findings. In fact patients >85 years have a 472% increase in risk-adjusted mortality during a hospital admission compared to younger patients. However, despite the substantially higher mortality and morbidity associated with age, there has been a marked improvement in surgical outcomes in the elderly population. (more…)

MedicalResearch.com Interview with: Ethan K Gough, PhD candidate Department of Epidemiology Biostatistics and Occupational Health McGill University, Montreal, QC, Canada MedicalResearch.com: What are the main findings of the study? Answer: Antibiotic use produces significant gains toward expected growth in children, for their age and sex, from low- and middle-income countries. Children included in our study were generally smaller in height and weight than adequately nourished children of the same age, reflecting the spectrum of stunting and wasting malnutrition seen in low- and middle-income countries. Antibiotic use had a larger impact on weight than height, and the effect on weight was larger in populations who may be at greater risk of infections and early mortality, such as populations with a high prevalence of HIV infection or exposure, and a high prevalence of severe acute malnutrition.

Christophe Moreno, MD, PhD Directeur clinique, clinique d’Hépatologie Service de Gastroentérologie Hépatopancréatologie et Oncologie DigestiveMedicalResearch.com Interview with: Christophe Moreno, MD, PhD Directeur clinique, clinique d’Hépatologie Service de Gastroentérologie Hépatopancréatologie et Oncologie Digestive MedicalResearch.com: What are the main findings of the study? Dr. Moreno: The RESTORE study is an open label, phase 3 study, evaluating Simeprevir in combination with PegIFN and ribavirin in genotype 4 Chronic Hepatitis C patients, either naïve or treatment experienced. Results of this study demonstrated high efficacy of this combination, with an overall SVR rate of 65.4%. Efficacy is particularly high in treatment naïve and prior relapsers patients, with SVR rate of 82.9% and 86.4%, respectively. Moreover, treatment naïve patients and prior relapsers were eligible to a shorter treatment duration of 24 weeks if they met response-guided therapy (RGT) criteria (defined by an HCV RNA below 25 at week 4 and undetectable at week 12). 89.5% met RGT criteria. Of those, 94.1% achieved a SVR. (more…)

Dr. Soylemez Wiener: The main finding is that evaluation of pulmonary nodules to determine whether or not they are cancerous is inconsistent with clinical practice guideline recommendations in almost half of cases, suggesting there is room for improvement in clinical care of these patients. Patients with pulmonary nodules are sometimes evaluated more aggressively than they should be (18%), which can cause harms to patients from unnecessary invasive tests (biopsies or surgery) or unneeded radiation exposure from imaging studies. Still more patients (27%) are followed less aggressively than they should be, which in the worst case scenario could lead to delays in the diagnosis and treatment of cancer. It is particularly important to improve care of these patients now, because new guidelines from the US Preventive Services Task Force recommend CT screening for lung cancer screening, which often finds pulmonary nodules that require evaluation.

Zhang, Xuan MD Professor of Medicine Dept. of Rheumatology Peking Union Medical College Hospital Beijing,China,100730MedicalResearch.com Interview with: Zhang, Xuan MD Professor of Medicine Dept. of Rheumatology Peking Union Medical College Hospital Beijing,China,100730 and Dr. Peter E. Lipsky, MD Formerly National Institute of Arthritis and Musculoskeletal and Skin Diseases National Institutes of Health, Bethesda, MD, MedicalResearch.com: What are the main findings of the study? Prof. Zhang & Lipsky--The results of this study indicate that TwHF is effective for the treatment of active rhematoid arthritis (RA). Importantly, these are the first data indicating that TwHF is effective in DMARD-naïve patients with active rheumatoid arthritis. At week 24, TwHF monotherapy resulted in significant improvement of disease activity, including pain assessment, the patient’s and physician’s global assessment, tender joint counts, swollen joint counts, ESR, CRP, and HAQ and SF-36 scores. MTX monotherapy and TwHF monotherapy had similar efficacy as shown by ACR20, ACR50 and ACR70 response criteria, EULAR and cDAI good response criteria, as well as DAS28 remission criteria and low disease activity(LDA) rate. The efficacy of TwHF was not inferior to that of MTX, and MTX +TwHF combination therapy was more effective than monotherapy in treating active rhematoid arthritis. A safety evaluation of the study demonstrated that the frequency of total adverse events and severe adverse events of TwHF monotherapy was not significantly higher than that of MTX monotherapy, except for a slightly increased frequency of irregular menstruation.

MedicalResearch.com Interview with: Dagfinn Aune MS Department of Epidemiology and Biostatistics School of Public Health Imperial College London St. Mary's Campus Norfolk Place, Paddington, London W2 1PG, UK MedicalResearch.com: What are the main findings of the study? Answer: We conducted a systematic review and meta-analysis of studies examining the association between maternal body mass index (BMI) and risk of fetal death, stillbirth, neonatal, perinatal and infant death. We found that the risk of all these outcomes increased with greater BMI in a dose-response fashion. For example even within the high end of what is considered the normal BMI range (BMI of 24-25) there was a 10-20% increase in the relative risk, but the strongest relations were seen for those who were obese and morbidly obese with 30-60% and 2-3 fold increases in the relative risk respectively (depending on the outcome examined).

Dr. Feng He Wolfson Institute of Preventive Medicine Barts and The London School of Medicine and Dentistry Queen Mary University of London, London, UKMedicalResearch.com Interview with: Dr. Feng He Wolfson Institute of Preventive Medicine Barts and The London School of Medicine and Dentistry Queen Mary University of London, London, UK
MedicalResearch.com: What are the main findings of the study? Dr. He:
  • The UK salt reduction program has led to a fall in population blood pressure and thereby contributed to the reduction in stroke and heart disease deaths.
  •  In 2003, the UK Food Standards Agency and CASH (Consensus Action on Salt & Health) developed a salt reduction program. As approximately 80% of the salt in the diet is added to food by the food industry i.e. in processed foods, fast foods, canteen and restaurant foods etc, the public have no choice about eating it. Therefore progressive incremental targets to limit the amount of salt for each food category were set, which the industry had to achieve in a specified time. Reductions first started in 2003 and are continuing to this day.
  • The salt reduction program has been very successful and led to a 15% reduction in the average salt intake of the population, from 9.5g per day in 2003 to 8.1g per day in 2011 (P<0.05).
  • Over the same time period, blood pressure fell in the adult population by 3 mm Hg systolic and 1.4 mm Hg diastolic (P<0.0001). Stroke and heart disease deaths fell by 42% (P<0.0001) and 40% (P<0.0001) respectively.
  • It is possible that these falls in blood pressure and deaths from stroke and heart disease were attributable to various factors such as changes in diet, lifestyles and the improvement in the treatment of cardiovascular disease and its risk factors. Our further analysis showed that the reduction in salt intake played an important role, particularly in the falls in blood pressure.
  •  In a further analysis, we looked at individuals who were not on any drug treatment for blood pressure and a correction was made for all other variables that could have influenced blood pressure, apart from salt. There was still a fall in adult population blood pressure of 2.7mm Hg systolic/ 1.1mm Hg diastolic, (P <0.0001). This reduction in blood pressure could therefore be largely attributed to the fall in salt intake.
  •  It is well established that raised blood pressure throughout its range is a major cause of stroke and heart disease. The reduction in salt intake that led to a fall in blood pressure would have played an important role in both stroke and heart disease deaths.
  • Despite considerable progress being made on salt reduction, the average salt intake in England is still high. In 2011, it was 8.1 g/day which is over a third more salt than the recommended level of 6g/day. Therefore continuing and much greater efforts are needed to achieve further reductions in salt intake to prevent the maximum number of stroke and heart disease deaths. (more…)

https://archinte.jamanetwork.com/article.aspx?articleid=1860496MedicalResearch.com Interview with: Dr. Jeffery  C. Huffman, M.D. Harvard Medical School Department of Psychiatry Massachusetts General Hospital, Boston MedicalResearch.com: What are the main findings of the study? Dr. Huffman: Depression and anxiety in cardiac patients are associated with adverse cardiac outcomes.  We completed a very low-intensity care management intervention to identify depression and anxiety disorders during a cardiac admission and then to assist in the monitoring and management of the condition over the next 24 weeks. There have been other care management trials in cardiac patients, but ours was the first to co-manage depression and anxiety, the first to initiate treatment in the hospital, the first to take a broad population of cardiac patients rather than a single diagnosis, and the first to use such a low-resource strategy with only a single part-time social worker to coordinate care. We found that the care management intervention was associated with significant improvements in mental health treatment, mental health related quality of life, depression, and function at 24 weeks compared to enhanced treatment as usual.  We did not find differences in anxiety, adherence, or cardiac readmissions.

Barbara A. Cohn, Ph.D. Director, Child Health and Development Studies A Project of the Public Health Institute Berkeley, CA 94709MedicalResearch.com Interview with: Barbara A. Cohn, Ph.D. Director, Child Health and Development Studies A Project of the Public Health Institute Berkeley, CA 94709   MedicalResearch.com: What are the main findings of the study?
  • Women with irregular menses had a statistically significant 2.4 fold increase in risk of death due to any form ovarian cancer, and a statistically significant 3-fold increase in risk of death due to late stage serous disease. Consistent with these findings, the incidence of late stage disease at diagnosis, and late stage serous cancer was increased about 2-fold in women with irregular menses.
  • Irregular menses was defined as irregular cycles (variation of 10 days or more) or infrequent cycles (>35 days) or history of annovulatory cycles identified during an in-person interview with women at an average age of 26 years or mentioned in their medical records. (more…)

Dr. Tannenbaum: The EMPOWER study showed that providing older patients with information about the harms of sleeping pill use led to discontinuation or dose reduction in 1-in-every 4 patients with longstanding use of benzodiazepines. Receipt of evidence-based information about drug harms resulted in a 8-fold higher likelihood of benzodiazepine cessation. Many physicians think that patients become too dependent on sedative-hypnotics to successfully discontinue. Regardless of age, sex, and duration of use, 27% of patients aged 65-95 in this study successfully completed the recommended 20-week tapering protocol during a 6-month time period and another 11% were in the process of tapering. EMPOWERing patients with evidence-based information therefore results in appropriate risk reduction. (more…)

MedicalResearch.com Interview with: Prof Dr Isabelle Mansuy Lab of Neuroepigenetics University/ETH Zürich Brain Research Institute Zürich SwitzerlandProf Dr Isabelle Mansuy Lab of Neuroepigenetics University/ETH Zürich Brain Research Institute Zürich Switzerland MedicalResearch.com: What are the main findings of the study? Prof. Mansuy: The mains findings are that the transmission of the effects of traumatic stress in early life involves small non-coding RNAs in sperm. The study shows that some microRNAs are in excess in the sperm of adult males subjected to trauma during early postnatal life, but are also altered in the brain and in blood, and that these alterations are associated with behavioral and metabolic symptoms including depressive behaviors, reduced risk assessment and altered glucose/insulin metabolism. Injecting sperm RNA in fertilized oocytes reproduces these symptoms and confirm that RNA are the responsible factors. (more…)

Finlay A McAlister MD Division of General Internal Medicine Patient Health Outcomes Research and Clinical Effectiveness Unit Epidemiology Coordinating and Research (EPICORE) Centre McGill University, Montréal, QuebecMedicalResearch.com Interview with: Finlay A McAlister MD University of Alberta, Edmonton, Canada MedicalResearch.com: What are the main findings of the study? Dr. McAlister: We tested 2 systems of case management on top of usual care (note that at baseline more than 3/4 of our study patients were already taking medications to lower blood pressure (BP) and/or cholesterol but none were at guideline-recommended targets). The first (our "control" group) was a nurse seeing patients monthly x 6 months, measuring their blood pressure and LDL cholesterol, counseling them about risk factor reduction strategies (including lifestyle and medication adherence), and faxing results of BP/cholesterol to their primary care physicians with advice to patients who had blood pressure or cholesterol above guideline-recommended targets to see their primary care physician. The second (our "intervention" group) was a pharmacist seeing patients monthly x 6 months, measuring their blood pressure and LDL cholesterol, counseling them about risk factor reduction strategies (including lifestyle and medication adherence), and faxing results of BP/cholesterol to their primary care physicians.  However, if patients had blood pressure or cholesterol above guideline-recommended targets instead of just recommending that the patient see their primary care physician the pharmacist provided them with a prescription for medication (or up-titration of their current medications) to address the uncontrolled risk factor. Both groups improved substantially over usual care, but the intervention group improved even more (13% absolute improvement in control of BP/cholesterol levels compared to the nurse-led control arm) .

MedicalResearch.com Interview with: Zoe Michaleff PhD Student, Musculoskeletal Division The George Institute for Global Health Sydney NSW 2000 Australia MedicalResearch.com: What are the main findings of the study? Answer: Our study showed that a 30 minute advice session with two phone call follow ups was as effective for chronic whiplash as the comprehensive physiotherapy exercise program in which participants received twenty, one-hour individually-tailored and supervised exercise sessions over a 12-week period. While people's pain and activity improved in both treatment groups, the most important finding is that there were no differences between groups. This finding held true for all outcome measures except for two secondary outcome measures of self rated recovery (global perceived effect) and functional ability (patient specific functional scale) which were in favour of the comprehensive exercise program however the size of these effects were too small to be considered clinically meaningful.

Dr Ola Vedin University of Uppsala, SwedenMedicalResearch.com Interview with: Dr Ola Vedin University of Uppsala, Sweden   MedicalResearch.com: What are the main findings of the study? Dr. Vedin: That self-reported tooth loss as a marker of periodontal disease is common in patients with established coronary heart disease and is associated with higher levels of LDL cholesterol, glucose levels, systolic blood pressure and waist circumference as well as diabetes and smoking, i.e. risk factors for coronary heart disease. Gum bleeding, another marker of periodontal disease, was associated with higher levels of LDL cholesterol and systolic blood pressure. In summary, patients with few remaining teeth and gum bleeding demonstrated a heavier burden of cardiovascular risk factors. (more…)

Ioannis Tarnanas M.Sc Senior Researcher Gerontechnology and Rehabilitation Research Group, ARTORG Centre for Biomedical Engineering, University of Bern, 3010 Bern, SwitzerlandMedicalResearch.com Interview with: Ioannis Tarnanas M.Sc Senior Researcher Gerontechnology and Rehabilitation Research Group, ARTORG Centre for Biomedical Engineering, University of Bern, 3010 Bern, Switzerland MedicalResearch.com: What are the main findings of the study? Answer: We examined 75 healthy older people and 134 patients with mild cognitive impairment. Our aim was to collect neuropsychological, neurophysiological, neuroimaging and behavioural data by means of a virtual reality serious game, in order to model the profile of the patients who will progress to dementia within the next 2-4 years. We found that the prediction based on the performance at the virtual reality based computerized assessment instrument is comparable to that of more established and widely accepted biomarkers, such as ERP and MRI. This can be explained by the cognitive fidelity and richness of behavioural data collected with virtual reality based measures, which directly reflect neurocognitive processes affected at a very early stage.

Amy Nunn, ScD, MS Assistant professor (research) of Behavioral and Social Sciences Brown University School of Public HealthMedicalResearch.com Interview with: Amy Nunn, ScD, MS Assistant professor (research) of Behavioral and Social Sciences Brown University School of Public Health MedicalResearch.com: What are the main findings of the study? Answer: The main findings are that people living in poor, mostly-minority urban neighborhoods, where health resources such as HIV testing and linkages to care are often lacking, are at a greater risk of contracting HIV and dying of AIDS. This is not because of differences in behavior. It's because they live in medically underserved areas where HIV incidence is very high and fewer people know their status. Fewer people knowing their status means fewer people on treatment. Fewer people on treatment means it's easier for people to come into contact with the virus, even if they don't engage in any higher risk behavior. In the paper, my colleagues and I call for increasing the focus of public health efforts on these neighborhoods where the epidemic is concentrated and contributing heavily to racial and economic disparities in AIDS mortality.

Pfeffer, M.D., Ph.D. Dzau Professor of Medicine Harvard Medical School Cardiovascular Division Brigham and Women's Hospital MedicalResearch.com: What are the main findings of the study? Dr. Pfeffer: We randomized 3445 patients with symptomatic heart failure and a left ventricular ejection fraction greater than or equal to 45% (heart failure with preserved ejection fraction or diastolic heart failure) to spironolactone or placebo and followed them for over 3 years. Our primary outcome the composite of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for management of heart failure was not significantly reduced in the group randomized to spironolactone. We did, however, observe that fewer patients in the spironolactone group were hospitalized for the management of heart failure following randomization. Spironolactone therapy was associated with higher incidence of  hyperkalemia and rises in serum creatinine. (more…)

dr_sabina-sieriMedicalResearch.com Interview with: Sabina Sieri, PhD Epidemiology and Prevention Unit Department of Preventive & Predictive Medicine Fondazione IRCCS Istituto Nazionale dei Tumori 20133 Milan – Italy MedicalResearch.com: What are the main findings of this study? Dr. Sieri: In our study we found that there was an increased risk of developing breast cancer from high saturated fat intake. High total and saturated fat intake were associated with greater risk of ER PR positive breast cancer. High saturated fat intake was also associated with a greater risk of HER2 negative disease. So, a high-fat diet increases breast cancer risk and, most conspicuously, a high saturated fat intake increases the risk of developing hormone-sensitive diseases, suggesting saturated fat involvement in the etiology of hormone-sensitive breast cancer.

Piotr Lewczuk Head,Lab for Clinical Neurochemistry and Neurochemical Dementia Diagnostics, Universitätsklinikum Erlangen, Department of Psychiatry and Psychotherapy, 91054 Erlangen, Germany MedicalResearch.com: What are the main findings of the study? Prof. Dr. med. Piotr Lewczuk: In our study, we investigated the concentrations of four isoforms of amyloid beta peptides in the blood of healthy young volunteers without memory complains. The participants were stratified into three groups according to their apolipoprotein E (APOE) genotype, which is the mostly investigated and generally accepted genetic risk factor for sporadic Alzheimer’s Disease (AD). It is known that the alterations of the amyloid beta metabolism are the earliest changes in the course of AD, occurring many years (or even decades) before the onset of the clinical symptoms, but it is actually not known how early these alterations start. Correspondingly, we wanted to investigate if healthy persons with genetic risk factor show changes in their amyloid beta metabolism already 30-40 years before the age when AD is usually diagnosed. We did not find any differences between the groups with and without APOE-driven risk, which might be carefully interpreted as no signs of Alzheimer’s Disease pathology in persons at risk at such an early life stage. Taken together, we think that the Alzheimer’s Disease pathology starts some 10-20 years before the beginning of the clinical symptoms, but not earlier. (more…)

Dr. Judy C. Boughey MD Professor of Surgery Mayo Clinic, Rochester MNMedicalResearch.com Interview with Dr. Judy C. Boughey MD Professor of Surgery Mayo Clinic, Rochester MN MedicalResearch.com: What are the main findings of the study?   Dr. Boughey: This study showed that the rate of reoperation after lumpectomy for breast cancer was significantly lower at Mayo Clinic in Rochester compared to national data. Mayo Clinic in Rochester uses frozen section analysis of margins at time of lumpectomy to direct any margin re-excisions during the surgery and therefore has a significantly lower rate of need for a second operation to ensure clean margins. The rate of reoperation was four times higher in the national data set than in the Mayo Clinic data set.

Answer: The main findings of our study are: 1) EPO treatment has an anti-inflammatory effect on white adipose tissue macrophage population during diet-induced obesity in addition to its associated metabolic improvements on glucose tolerance and insulin sensitivity in vivo. 2) In this model of obesity, EPO treatment was found to reduce M1-like [pro-inflammatory] and increased M2-like [anti-inflammatory] macrophages in visceral white adipose tissue depot. 3) In addition, EPO decreased circulating inflammatory monocytes. 4) These anti-inflammatory effects of EPO were found to be driven, at least in part, by direct EPO-R response in macrophages via Stat3 activation, where EPO effects on M2 but not M1 macrophages required interleukin-4 receptor/Stat6 axis. 5) The anti-inflammatory effects of EPO are not restricted to treatment with exogenous high dose EPO (1000U/kg), but also include endogenous physiological EPO levels as demonstrated by the series of studies conducted using ΔEpoR mice with EPO-R restricted to erythroid cells.
