MedicalResearch.com Interview with: Sneha Sridhar, MPH Kaiser Permanente, Division of Research 2000 Broadway, 3rd Floor Oakland, CA  94612 MedicalResearch.com: What are the main findings of the study?   Answer: We found that women whose weight gain during pregnancy exceeded the current Institute of Medicine (IOM) recommendations were 46% more likely to have an overweight or obese child at ages 2-5, compared to women who met the recommendations. The association was stronger among women who were of normal weight before pregnancy. These normal weight women were more likely to have an overweight or obese child if they gained either below or above the IOM recommendations. (more…)

MedicalResearch.com Interview with: Donald S. A. McLeod, FRACP, MPH Department of Population Health, QIMR Berghofer Medical Research Institute, Herston, Queensland, Australia MedicalResearch.com: What are the main findings of the study? Dr. McLeod: We examined the incidence of Graves’ disease and Hashimoto’s thyroiditis by race/ethnicity among U.S. active duty service personnel aged 20-54 years over a 15-year period (more than 20,000,000 person years follow-up). Cases were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes. In women, we found that Graves’ disease was almost twice as common among non-Hispanic black and Asian-Pacific Islander personnel compared with non-Hispanic white personnel.  While in men, non-Hispanic black and Asian-Pacific Islander personnel had over two-and-a-half times higher incidence compared with non-Hispanic white personnel. The opposite pattern existed for Hashimoto’s thyroiditis, with non-Hispanic white personnel having the highest incidence, and non-Hispanic black and Asian-Pacific Islander personnel the lowest incidence. Hispanic personnel did not have significantly different incidence compared to white personnel for either disorder. (more…)

Dr Hardeep Singh MD MPH  Chief of the health policy, quality & informatics program at the Veterans Affairs Center for Innovations in Quality, Effectiveness and Safety, based at the Michael E. DeBakey VA Medical Center in Houston, Texas Associate professor at Baylor College of Medicine in HoustonMedicalResearch.com Interview with: Dr Hardeep Singh MD MPH  Chief of the health policy, quality & informatics program at the Veterans Affairs Center for Innovations in Quality, Effectiveness and Safety, based at the Michael E. DeBakey VA Medical Center in Houston, Texas Associate professor at Baylor College of Medicine in Houston MedicalResearch.com: What are the main findings of the study? Dr Singh: We built estimates of diagnostic error by compiling and analyzing data from three previous studies. These studies evaluated situations such as unexpected return visits and lack of timely follow up and provided researchers with an estimated frequency of diagnostic error. This frequency was then applied to the general adult population. Diagnostic errors, which we defined as missed opportunities to make a correct or timely diagnosis based on available evidence—occur in about 5 percent of adults in the United States. (more…)

Dr. Muensterer: We looked at the functionality of Google Glass, a novel head-mounted mobile computer with integrated display, camera, microphone, and speaker, in the clinical environment. While the technology has a lot of promise to be useful for pediatric surgeons, in its current version, it also has significant limitations. The most obvious utilities are hands-free photo- and videodocumentation, looking up medical terminology on the internet, help with coding and billing activities, and hands-free telecommunication.

MedicalResearch.com Interview with: Nestor E. Vain M.D. Professor of Pediatrics, School of Medicine, University of Buenos Aires Vice-President, FUNDASAMIN (Foundation for Maternal Infant Health), Argentina Director, Neonatology, Hospital Sanatorio de la Trinidad Palermo and San Isidro, Buenos Aires MedicalResearch.com: What is the background of this study? Prof. Vain: Delayed umbilical cord clamping (DCC) is currently recommended by many professional associations. The main reason is that it decreases the incidence of iron deficiency in infancy, a very serious public health problem in developing countries, but also prevalent in the USA and in western Europe. Besides it has other advantages in premature infants such as better adaptation of the cardiovascular system to extra-uterine life. How does Delayed umbilical cord clamping work?. Approximately 30% of the fetal blood volume is in the placenta at the time of delivery. Waiting for a couple of minutes before clamping the cord allows for a large part of that blood volume to return to the infant. (this process is known as placental transfusion) Despite of these well known facts, and the absence of serious complications, the compliance with the recommendation of delayed umbilical cord clamping is low. Why is that? There may be a variety of reasons but we are certain that one very important one is that the majority of obstetricians and neonatologists believe that to achieve an efficient placental transfusion and to avoid a negative effect from gravity, it is necessary to hold the infant at or below the level of the vagina during those 2 minutes. In that way the procedure is cumbersome and it prolongs unwillingly a separation between the infant and the mother. The believe that the infant needs to be at that low level is based on small studies performed more than 35 years ago. (more…)

Jordan Feld MD MPH Toronto Western Hospital Liver Center University Health Network Sandra Rotman Centre for Global HealthMedicalResearch.com Interview with: Jordan Feld MD MPH Toronto Western Hospital Liver Center University Health Network Sandra Rotman Centre for Global Health MedicalResearch.com:  What are the main findings of the study? Dr. Feld: The SAPPHIRE 1 study was an international, large (631 patients) Phase 3 study of 3 direct acting antivirals combined with ribavirin for 12 weeks for the treatment of patients with genotype 1 hepatitis C virus (HCV) infection without cirrhosis.  The antivirals used were ABT-450, which is a protease inhibitor that is boosted with ritonovir to allow for once daily dosing along with ombitasvir (formally ABT 267), a potent NS5A inhibitor and dasabuvir (formerly known as ABT 333), a non-nucleoside polymerase inhibitor.  The ABT-450, ritonovir and ombitasvir were all co-formulated into a single tablet and dasabuvir was taken twice daily, as was ribavirin. The results of the study showed that the treatment is highly effective with 96% of patients achieving a sustained virological response (SVR) at 12 weeks after completing treatment.  SVR is a cure of HCV infection.  Importantly, patients with genotypes 1a and 1b had similar results with a rate of SVR12 of 95% in genotype 1a and 98% in genotype 1b.  These results were clearly superior to a historical control treatment with telaprevir combined with peginterferon and ribavirin.  Baseline factors were not predictive of outcome, including factors associated with non-response to interferon such as the IL28B genotype, baseline HCV viral load and older age.

MedicalResearch.com Interview with: Jeffrey R. Parker Assistant Professor of Marketing Robinson College of Business - Georgia State University MedicalResearch.com: What are the main findings of the study? Mr. Parker: Recently, there has been quite a bit of debate about the effectiveness of providing dish-specific calorie information (a practice called “calorie posting”) on restaurant menus in terms of the healthiness of consumers’ food choices. Some results suggest that such labels lead to lower-calorie choices, while other research shows that there is no effect. We examined one factor that might impact the effectiveness of calorie posting: the practice of grouping low-calorie options on a menu and labeling this category accordingly (i.e., incorporating a low-calorie menu/category in the menu)—which we call “calorie organizing”—as opposed to simply allowing them to appear in their natural categories with the caloric content appearing in the dish descriptions (e.g., Sandwiches, Salads, Pastas, etc.). On the surface it seems obvious that making low-calorie options easier to find—by giving them their own labeled category on the menu—would bolster the positive effects of calorie posting. However, we found the opposite: additionally calorie organizing an already calorie-posted menu regularly eliminates the benefits that calorie posting can have. We argued and found evidence indicating that the underlying cause of this effect stems from how consumers make decisions. Restaurant menus are often too large for a consumer to seriously consider all of the dishes. Some consumers typically eliminate large portions of the menu on the basis of simple criteria (e.g., “I don’t like seafood.”, “It’s too early to eat pasta.”, etc. ). Since consumers generally make negative inferences about low-calorie dishes (e.g., “They don’t taste good.”, “They are small dishes.”, etc.) they are likely to summarily dismiss all of the low-calorie options early in the decision process when the menu is calorie-organized (i.e., has grouped the low-calorie dished and labeled the new category accordingly). Thus, they are likely to choose as poorly as they would were they given no calorie information. In contrast, when the menu is just calorie-posted, and the low-calorie dishes appear in their natural categories, these dishes are unlikely to be dismissed in the early choice-simplification stages. Thus, low-calorie dishes are likely to be seriously considered in the final decision process, during which the pros and cons of dishes can be more comprehensively traded off, and are therefore more likely to be chosen.

Rine Nakanishi, MD, PhD Los Angeles Biomedical Research Institute MedicalResearch.com Interview with: Rine Nakanishi, MD, PhD Los Angeles Biomedical Research Institute MedicalResearch.com: What are the main findings of the study? Dr. Nakanishi: With growing evidence that a measurement of the buildup of calcium in coronary arteries can predict heart disease risk, Los Angeles Biomedical Research Institute (LA BioMed) researchers found that the process of "calcium scoring" was also accurate in predicting the chances of dying among adults with little or no traditional risk factor of heart disease. The study conducted by LA BioMed researchers examined 5,593 adults with no known heart disease and zero or minimal risk factor of heart disease -- including hypertension, dyslipidemia, diabetes, current smoking and family history of heart disease -- who had undergone coronary artery calcium screening by non-contrast cardiac computed tomography from 1991-2011. Among the adults in the study, even those with low coronary artery calcium scores of 1-99 were 50% more likely to die of heart disease than adults with a calcium score of zero. Adults with moderate scores of 100-399 were 80% more likely to die from heart disease than those with a score of zero, and those with scores of 400 or more were three times more likely to die from heart disease, when compared to adults with no calcified plaque buildup, or a score of zero.

Answer:  We conducted the first and largest population-based cohort study to evaluate the association of obstructive sleep apnea (OSA) and osteoporosis in a 6-year follow-up investigation of an Asian population. OSA is characterized by repetitive episodes of apnea/hypopnea and hypoxia in tissue, which might impact the bone metabolism. The results of the study showed that patients with obstructive sleep apnea had 2.74 times the risk of osteoporosis than patents without obstructive sleep apnea after adjustment for the patient`s characteristics and comorbidities. Across all age groups and sex groups, individuals with OSA had higher incidence rate of osteoporosis than individuals without obstructive sleep apnea. Subgroup analysis showed that older patients and female patients had a higher risk for osteoporosis than their younger and male counterparts. (more…)

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.

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.

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…)

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.

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…)

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.

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.
