MedicalResearch.com: Interview with: Dr. Hsien Seow PhD Cancer Care Ontario Research Chair in Health Services Research Asst Professor, Dept of Oncology, McMaster University Hamilton, OntarioDr. Hsien Seow PhD Cancer Care Ontario Research Chair in Health Services Research Asst Professor, Dept of Oncology, McMaster University Hamilton, Ontario   MedicalResearch: Why did you conduct this study? Dr. Seow: While palliative care has gained recognition as a service that can improve patient outcomes and reduce health care costs at the end of life, especially in hospitals and hospices, much less attention has focused on providing inter-disciplinary palliative care in the community and home. There have been several randomized trials that showed mixed evidence that inter-disciplinary teams of specialist palliative care providers can reduce acute care utilization in the community; however team size and team composition varied in prior trials. This variation has not been researched as a cause for the mixed outcomes.

MedicalResearch.com: Interview with: Dr Christian Beyer Department of Internal Medicine 3 - Rheumatology and Immunology University of Erlangen-Nuremberg, Germany. MedicalResearch: What are the main findings of the study? Dr. Beyer: Our study aimed to identify specific micro RNAs as preditors for osteoarthritis. Osteoarthritis is a progressive and long-standing disease. It's early and very early stages are clinically silent, which means that patients do not experience symptoms or present with obvious signs of the disease. Preventive measures and early therapies, however, would be probably most effective in treating this very common condition. Thus, markers to identify individuals at risk for osteoarthritis or in early clinical stages are highly important, but are not available for clinical routine yet. Micro RNAs are group of molecules that have signaling functions in the human body and that can reflect states of disease and health. Since they are very stable and easily accessible in the peripheral blood (by venous puncture without complicated procedures like biopsies), the represent promising biomarkers in many different fields of medicine. In this context, we wondered if specific micro RNAs might predict the development of severe osteoarthritis. Indeed, we could identify thre micro RNAs, named mir-454, mir-885-5p and let-7e, out of a total of 377 micro RNAs, that help to predict the risk for developing severe osteoarthritis.

Tetyana Kendzerska MD, PhD Postdoctoral Fellow Institute for Clinical Evaluative Science, Sunnybrook Health Sciences Center, Toronto, ONMedicalResearch.com Interview with: Tetyana Kendzerska MD, PhD Postdoctoral Fellow Institute for Clinical Evaluative Science, Sunnybrook Health Sciences Center, Toronto, ON MedicalResearch: What are the main findings of the study? Dr.  Kendzerska: Based on a large sample of more than 8,500 participants with suspected sleep apnea, our study shows that among people with obstructive sleep apnea (OSA), and controlling for risk factors for diabetes development, initial OSA severity predicted risk for incident diabetes. Measures of the physiologic consequences of OSA (e.g., low level of oxygen, sleep deprivation) were also risk factors for diabetes in this population.

William D. Chey, MD, AGAF, FACG, FACP, RFF Professor of Medicine Director, GI Physiology Laboratory Co-director, Michigan Bowel Control Program University of Michigan Health SystemMedicalResearch.com Interview with: William D. Chey, MD, AGAF, FACG, FACP, RFF Professor of Medicine Director, GI Physiology Laboratory Co-director, Michigan Bowel Control Program University of Michigan Health System MedicalResearch: What are the main findings of the study? Dr. Chey: Opiate analgesics are the most commonly prescribed medications in the US. GI side effects are common in patients who opiates. Constipation is the most common and most bothersome GI side effect of opiates. Peripherally acting mu opioid antagonists have been shown to benefit a subset of patients with opiate induced constipation. In 2 large, randomized, placebo controlled phase III trials, the peripherally acting, mu-opioid antagonist naloxegol was found to improve constipation in patients taking opioid analgesics for noncancer pain. Response rates were significantly higher with 25 mg of naloxegol than with placebo (intention-to-treat population: study 04, 44.4% vs. 29.4%, P = 0.001; study 05, 39.7% vs. 29.3%, P = 0.02) in both studies. Benefits were seen with the lower 12.5 mg dose in one of the studies (intention-to-treat population, 40.8% vs. 29.4%, P = 0.02). An interesting aspect of this study was the a priori inclusion of patients who had tried and failed to respond to other laxatives prior to enrollment. Response rates in this population were similar to the overall population (patients with an inadequate response to laxatives: study 04, 48.7% vs. 28.8%, P = 0.002; study 05, 46.8% vs. 31.4%, P = 0.01). Pain scores and daily opioid dosing were similar among the three groups before and after treatment.

MedicalResearch.com Interview with: Stephanie F. Polites, MD Department of Surgery and Michael B. Ishitani, MD Department of Pediatric Surgery Mayo Clinic, Rochester, Minnesota MedicalResearch: What are the main findings of the study? Answer: Though most injuries were in boys, 20% of the injuries occurred in girls. Extremity fractures and head injuries were the most common injuries with older children and boys more likely to sustain extremity fractures while younger children and girls were more likely to have head injuries or concussions. Life threatening injuries were rare, which is reassuring.

Laurie Lambert, PhD Unité d'évaluation en cardiologie Institut national d'excellence en santé et en services sociaux (INESSS) Montréal, QuébecMedicalResearch.com Interview with: Laurie Lambert, PhD Unité d'évaluation en cardiologie Institut national d'excellence en santé et en services sociaux (INESSS) Montréal, Québec MedicalResearch: What are the main findings of the study? Dr. Lambert: Patients with ST-elevation myocardial infarction (STEMI) are frequently transferred for percutaneous coronary reperfusion from a hospital without this capability. Favourable outcomes depend on minimizing delays to treatment. A major component of delay is the time from the patient’s arrival at the first hospital’s emergency department to departure to the hospital where percutaneous reperfusion will be performed, the ‘door-in-door-out’ time or DIDO. We characterized this component of delay in a systematic field evaluation of STEMI treatment over a large and populous geographic area. The major contributors to DIDO time were the delays
  • (1) from the initial in-hospital ECG acquisition to transfer activation by the emergency physician and
  • (2) from arrival of the transfer ambulance at the first hospital to departure of the ambulance for the primary percutaneous coronary intervention center. When the DIDO interval was timely (30 minutes or less as recommended by guidelines), reperfusion treatment was far more frequently within guideline-recommended delays (90 minutes or less). In fact, this benchmark of DIDO time was met in only 14% of cases. We identified a number of factors associated with untimely DIDO, an important one being an ambiguous presenting ECG. DIDO times were faster when patients arrived at the first hospital by ambulance particularly when retransfer to the second hospital was with the same ambulance that had remained on standby.

Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in DenmarkMedicalResearch.com Interview with: Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in Denmark MedicalResearch: What are the main findings of the study? Dr. Nykjaer: It is well known that ADHD is a complex condition caused by a number of factors including genetic and environment. However, approximately 75% etiology is considered to be genetic and a large body of investigations suggests that it is multiple genes each with a moderate effect that is responsible for conferring susceptibility to ADHD. We have here found one single gene the dysfunction of which is sufficient to trigger the disease.  The gene encodes a receptor, SorCS2, which ensures correct wiring our reward system during embryonic development. Malfunction of the receptor causes ADHD-like symptoms in mice. It is well accepted that ADHD predisposes to psychiatric disorders and genetic reports have linked variations in the SorCS2 gene with schizophrenia. Studies are currently ongoing to evaluate if mutations disrupting the function of SorCS2 may also result in schizophrenia. If this is the case we have come closer to an explanation for the link between ADHD and psychiatric disorders. In the future when prenatal genetic screening becomes established, non-sense mutations in the SorCS2 gene can be used to predict that the child will develop ADHD with 100% certainty.

Rachel Thompson PhD Postdoctoral Research Fellow The Dartmouth Center for Health Care Delivery Science Dartmouth CollegeMedicalResearch.com: Interview with Rachel Thompson PhD Postdoctoral Research Fellow The Dartmouth Center for Health Care Delivery Science Dartmouth College MedicalResearch: What are the main findings of the study? Dr. Thompson: This study, which surveyed 417 women aged 15-45 years and 188 contraceptive care providers in 2013, found important differences in what matters most to these two groups when it comes to discussing and deciding on a contraceptive method. Women’s most important question when choosing a contraceptive was “Is it safe?” – this was in the top three questions for 42% of women but only 21% of providers. Alternatively, providers’ most important question was “How is it used?”. Information on side effects and how a method actually works to prevent pregnancy was also a higher priority for women than for providers.

Gabriella Johansson Occupational and Environmental Medicine Lund University Hospital Lund, SwedenMedicalResearch.com Interview with: Gabriella Johansson Occupational and Environmental Medicine Lund University Hospital Lund, Sweden   MedicalResearch: What are the main findings of the study? Answer: Our main focus was to study hairdressers’ exposure to carcinogenic aromatic amines. We found that the concentrations of the carcinogenic compound o-toluidine in blood increased with the number of treatments per week of light color permanent hair dyeing and hair waving treatments. Another aromatic amine, m- toluidine (assessed as not classifiable as carcinogenic to humans owing to a lack of data) in blood, increased with the number of treatments per week of light color hair dyeing and all other hair dyeing.

MedicalResearch.com Interview with Dr. Maryam Farvid MSc, Ph.D. Takemi fellow, and Associate ArofessorMedicalResearch.com Interview with Dr. Maryam Farvid MSc, Ph.D. Takemi fellow, and Associate Arofessor Senior author: Prof Walter Willett Department of Nutrition, Harvard School of Public Health, Boston, MA, MedicalResearch: What are the main findings of the study? Dr. Farvid: Compared to women who had one serving per week red meat, those who consumed 1.5 serving per day red meat had a 22 percent higher risk of breast cancer. Red meat intake is associated with breast cancer risk in a dose-response manner. Each additional serving/day increase in total red meat was associated with a 13% increase in risk of breast cancer. Furthermore, each additional serving/day of poultry was associated with a 25% lower risk of postmenopausal breast cancer. Substituting one serving/day of legumes for one serving/day of red meat was associated with a 15% lower risk of breast cancer, substituting one serving/day of poultry for one serving/day of red meat was associated with a 17% lower risk of breast cancer overall, and substituting one serving/day of combined legumes, nuts, poultry, and fish for one serving/day of red meat was associated with a 14% lower risk of breast cancer.

Roumie, MD MPH Associate Professor Internal Medicine and Pediatrics Institute for Medicine and Public Health Vanderbilt University Staff Physician VA Tennessee Valley Healthcare System Nashville TN 37212 MedicalResearch: What are the main findings of the study? Dr. Roumie: This retrospective cohort study compared time to acute myocardial infarction (AMI), stroke, or death among Veterans with diabetes that were initially treated with metformin, and subsequently added either insulin or sulfonylurea. Among 178,341 Veterans on metformin monotherapy, 2,948 and 39,990 added insulin or sulfonylurea, respectively. Patients were about 60 years old, about 35% had history of heart disease or stroke, had been on metformin for an average of 14 months and their hemoglobin A1c was 8.1% at the time of addition of the second medication. Compared to those who added a sulfonylurea, those who added insulin to metformin had a 30% higher risk of the combined outcome of heart attack, stroke, and all-cause mortality. Although new heart attacks and strokes occurred at similar rates in both groups, mortality was higher in patients who added insulin.

Prof. Sjöström: In obese diabetic subjects, the 2-year diabetes remission was 72% in bariatric surgery patients but only 16% in obese controls obtaining conventional obesity and diabetes treatment. After 15 years, 30% were in remission in the surgery group and 6.5% in the control group. In addition, the 20-year incidence of diabetes complication was 30 -55% lower in surgery than control patients.

Fergus Shanahan, MD, DSc Professor and Chair, Department of Medicine, and Director, Alimentary Pharmabiotic Centre University College Cork, National University of IrelandMedicalResearch.com Interview Fergus Shanahan, MD, DSc Professor and Chair, Department of Medicine, and Director, Alimentary Pharmabiotic Centre University College Cork, National University of Ireland MedicalResearch: What are the main findings of the study? Professor Shanahan: We already know that most (if not all) of the elements of a modern lifestyle in socio-economically developed societies influence the composition and performance of the microbiota colonising the human body. The composition of the microbiota or disturbances of it have been linked with an increased risk of various chronic non-communicable diseases including immune-allergic disorders and metabolic diseases including obesity. In particular, loss of microbial diversity is a feature of many of these disorders. The most important aspect of our study is that draws attention to the possibility that exercise may have a beneficial effect on the microbiota and is associated with a more diverse microbiota.

Mike Morgan, MD R2 Division of Emergency Medicine University of Utah School of MedicineMedicalResearch.com Interview with: Mike Morgan, MD R2 Division of Emergency Medicine University of Utah School of Medicine MedicalResearch: What are the main findings of the study? Dr. Morgan: Our paper is a review of the literature. So we do not present original data or findings. What we do is present new ideas about what drove the evolution of the hominin (bipedal ape) face. Studies of injuries resulting from fights show that when modern humans fight the face is the primary target. The bones of the face that suffer the highest rates of fracture from fights are the bones that show the greatest increase in robusticity during the evolution of early bipedal apes, the australopiths. These are also the bones that show the greatest difference between women and men in both australopiths and modern humans. What needs to be explained about facial differences in women and men is that in both apes and humans, males are much more violent than females and most male violence is directed at other males. Because males are the primary target of violence, one would expect more protective buttressing in males and that is what we find.

Mainous III, PhD Chair and Florida Blue Endowed Professor Department of Health Services Research, Management and Policy Professor of Community Health and Family Medicine University of Florida Health Science Center Gainesville, FL 32610 MedicalResearch: What are the main findings of the study? Professor Arch Mainous: This study focused on prediabetes, which is a high risk state for developing diabetes and associated complications. We investigated the national prevalence of prediabetes in England between 2003 and 2011. We found that the prevalence of prediabetes rose substantially in that time period from 11.6% to 35.3%. Further, by 2011 more than half of the population who were 40 years of age and older and were overweight had prediabetes. Minority ethnic groups are particularly affected.

Lee, Pharm.D., Ph.D. Assistant Professor Department of Pharmacy Practice College of Pharmacy Oregon State University/Oregon Health and Science University Portland OR, 97239 MedicalResearch: What are the main findings of the study? Dr. Lee: We found that older men taking a statin were less physically active and had more sedentary behavior. They had about 37 minutes of less moderate exercise per week. For comparison, the American heart Association recommends about 40 minutes of moderate activity 3-4 times per week. We also found that those that started using a statin during the study had the largest drop in physical activity.

Usher-Smith Clinical Lecturer in Primary Care The Primary Care Unit, University of Cambridge Strangeways Research Laboratory Cambridge, United Kingdom MedicalResearch: What are the main findings of the study? Dr Usher-Smith: Our systematic review identified 25 risk models that have the potential to identify individuals at higher risk of developing melanoma. Comparison between the different models was difficult due to the lack of validation studies and heterogeneity in choice and definition of variables. We were, however, able to show that most include well established risk factors and that, despite including a range of different variables, there is very little heterogeneity in the discriminatory ability of the models. There was also little difference in model performance between those scores suitable for self-assessment and those requiring a health care professional, suggesting potential for use at a population level to identify people at higher risk of melanoma.

Ayal A. Aizer, MD, MHS Harvard Radiation Oncology Program Boston, MAMedicalResearch Interview with: Ayal A. Aizer, MD, MHS Harvard Radiation Oncology Program Boston, MA MedicalResearch: What are the main findings of the study? Dr. Aizer: We studied Americans between the ages of 20-40 using the SEER Database (a national cancer registry) and found that patients who had insurance were more likely to present with localized (curable) versus metastatic (generally incurable) cancer. Patients with localized tumors were more likely to receive the appropriate treatment and, most importantly, survived longer than patients without insurance. Our analysis accounted for demographic and socioeconomic differences between patients who were insured versus uninsured. Our results indicate that insurance status is a powerful predictor of outcome among young adults with cancer. The Affordable Care Act, which will likely improve insurance coverage nationally, may yield improved cancer outcomes among Americans.

Lamuela-Raventos, PhD Associate Professor Department of Nutrition and Food Science School of Pharmacy, University of Barcelona MedicalResearch: What are the main findings of the study? Dr. Lamuela-Raventós: We have found an inverse relationship between polyphenol intake and risk of overall mortality among elderly subjects at high cardiovascular risk. Adjusting for confounders and comparing the highest versus the lowest quintiles of intake, total polyphenols were inversely associated with total mortality (HR=0.63, 95 CI=0.41-0.97, P-trend=0.12), as well as stilbenes (HR=0.48, 95 CI=0.25-0.91, P-trend=0.04) and lignans (HR=0.60, 95 CI=0.37-0.97, P-trend=0.03). In fact, our results showed that all polyphenols subgroups, except for dihydrochalcones, trended to be protective although their intake did not reach statistical significance. In stratified analyses we also found a stronger association between total polyphenol intake and mortality risk for women and for those who did not drink alcohol.

Mauro Di Bari, MD, PhD Associate Professor of Medicine - Geriatrics Director, School of Geriatrics Vice-president, School of Physiotherapy University of Florence and Azienda Ospedaliero-Universitaria Careggi Florence ItalyMedicalResearch Interview with: Mauro Di Bari, MD, PhD Associate Professor of Medicine - Geriatrics Director, School of Geriatrics Vice-president, School of Physiotherapy University of Florence and Azienda Ospedaliero-Universitaria Careggi Florence Italy MedicalResearch: What are the main findings of the study? Professor Di Bari: This study is based on the AMI-Florence 2 registry, which recorded all acute coronary syndromes (ACS) occurring in one year in the metropolitan area of Florence, Italy. This area has one of the top prevalence figures in the country for application of percutaneous coronary intervention (PCI) to treat ACS, at least in cases with ST-segment elevation myocardial infarction (STEMI). Nevertheless, in our study the procedure turned out to be largely underused in older, complex patients, who mostly had NSTEMI: the greater the background risk (as expressed by the Silver Code, a simple, validated prognostic tool based of administrative data), the lower the chances for application of PCI, independent of possible contraindications to PCI, such as anaemia or renal insufficiency. At the same time, the long-term survival advantage offered by PCI increased with increasing background risk: when comparing patients receiving and not receiving PCI across strata identified on the basis of the Silver Code, one-year survival was only marginally greater in patients treated with PCI when their Silver Code score suggested low background risk, whereas the mortality gradient increased progressively along with Silver Code score, to reach its maximum in patients with the greatest values of Silver Code score. Within the limits of an observational study, cardiac and non-cardiac comorbidities, contraindications to PCI, clinical characteristics of the ACS and hospital of admission could not justify these findings.

Dr. Barbara Pockaj, MD Professor of Surgery Mayo Clinic, ArizonaMedicalResearch.com Interview Invitation Dr. Barbara Pockaj, MD Professor of Surgery Mayo Clinic, Arizona   MedicalResearch: What are the main findings of the study? Dr. Pockaj: The study analyzed 515 triple negative breast cancer samples using a multi-platform approach including whole genome mRNA expression, protein expression, gene copy number changes and gene sequencing for immune markers. The study found that a cohort of the triple negative breast cancer patients had high expression of PD-L1 (program death ligand) and other immune regulators such as CTLA-4 (Cytotoxic T-lymphocyte Antigen) and IDO-1 (indoleamine 2,3-dioxygenase).  High PD-L1 expression was found in patients whose tumors were triple negative and androgen receptor negative.  High PD-L1 expression was related to DNA repair gene abnormalities including BRCA1.

Dr. Toriola: Very little is known about the impact of vitamin D in prognosis among cancer patients. This knowledge is of importance because of the increasing number of people living cancer and the high prevalence of vitamin D deficiency among cancer patients. We conducted a systematic review of studies published to date on the association of circulating vitamin D (25-OHD) levels with prognosis among cancer patients. This review suggests that higher circulating vitamin D levels may improve overall survival among breast and colorectal cancer patients but there is paucity of information on the role of circulating vitamin D levels in prognosis among patients with other cancer types.

Dr David A Hanauer MD MS Department of Pediatrics University of Michigan Medical School Ann Arbor, MIMedicalResearch.com Interview with: Dr David A Hanauer MD MS Department of Pediatrics University of Michigan Medical School Ann Arbor, MI   MedicalResearch: What are the main findings of the study? Dr. Hanauer: In this study we analyzed requests made by patients who wanted to make changes to their medical record. The goal was to develop an understanding of what the main reasons were for making a request to change the medical record, and what types of information they wanted changed. One of the main findings was that about half of all requests were ultimately approved.  This suggests that patients reviewing their records can detect errors and have them corrected, which could ultimately lead to a more accurate record for a patient. In essence, giving patients the opportunity to further participate in their care by allowing them to review their record can lead to the identification and correction of errors or omissions.

Dr. Neuhausen: Medicaid Disproportionate Share Hospital (DSH) payments keep safety-net hospitals financially viable because these hospitals play such a critical role caring for the uninsured and Medicaid patients, providing trauma care and other vital community services, and training future health providers.  The Affordable Care Act (ACA) reduces these DSH payments because the ACA's authors assumed that safety-net hospitals would receive increased revenue from Medicaid expansion and therefore, have less need for DSH payments.  However, we found that California’s DSH need will actually increase because of medical cost inflation, low Medicaid payment rates, and the high number of people who will remain uninsured.  As a result, the DSH reductions will create funding gaps that must be filled to ensure the financial stability of safety-net hospitals.  The financial outlook for California’s safety-net hospitals is still much better under ACA than it would have been without the ACA.  In the absence of the ACA, California’s public hospitals would have had an additional $1.5 billion in costs for uncompensated care for the uninsured and would be facing a financial crisis.

Professor Marion M. Hetherington BSc (Hons) DipEd DPhil Institute of Psychological Sciences University of Leeds , Leeds, EnglandMedicalResearch.com Interview with: Professor Marion M. Hetherington BSc (Hons) DipEd DPhil Institute of Psychological Sciences University of Leeds , Leeds, England MedicalResearch: What are the main findings of the study? Professor Hetherington: This study was part of a much larger, funded project called HabEat (European Community’s Seventh Framework Programme (FP7/2007-2013) under the grant agreement n°245012. In this study we investigated the effects of offering a new vegetable (artichoke puree) to 332 children in the UK, Denmark and France from weaning age to 38 months. During the experiment each child was given between five and 10 servings of at least 100g of the artichoke puree in one of three versions: basic; sweetened, with added sugar; or added energy, where vegetable oil was mixed into the puree. There was a strong effect of repeated exposure with no additional, clear benefit of adding sweetness or energy. Thus little difference in how much was eaten between children fed basic puree and those who ate the sweetened puree. This suggests that making vegetables sweeter does not make a significant difference to the amount children eat.
