MedicalResearch.com Interview with: [caption id="attachment_22551" align="alignleft" width="200"]Dr Nicola Lindson-Hawley PhD Cochrane Tobacco Addiction Group (TAG) Managing Editor Dr. Lindson-Hawley[/caption] Dr Nicola Lindson-Hawley PhD Cochrane Tobacco Addiction Group (TAG) Managing Editor MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Lindson-Hawley: For many people, the obvious way to quit smoking is to cut down gradually until they stop.  After all, that’s how we accomplish most other goals that are hard.  With addictions other than smoking, we aim to get people to cut down gradually rather than stop abruptly.  But with smoking, the norm is to advise people to stop all at once.  Around the world, physicians and others who support smoking cessation help people to quit abruptly and not to cut down first.  However, if physicians are not providing support to people who want to quit by reduction, then they will have less chance of success as we know that people who receive support to quit are more likely to succeed.  On the other hand, if cutting down is a bad way to quit, then we need to persuade people to abandon their common sense idea and quit abruptly instead. Therefore, this study investigated this by comparing a group of smokers advised to quit gradually by cutting down with a group who quit all at once. What we found was that cutting down first, was a less successful way to quit than smoking as normal and then stopping. Smokers who quit abruptly were 25% more likely to have quit after 4 weeks than those who quit gradually.
Author Interviews, BMJ / 15.03.2016

MedicalResearch.com Interview with: [caption id="attachment_22661" align="alignleft" width="100"]Sílvia Mamede, MD, PhD Associate professor Institute of Medical Education Research Rotterdam Erasmus MC Rotterdam, The Netherlands Dr. Silvia Mamede[/caption] Sílvia Mamede, MD, PhD Associate professor Institute of Medical Education Research Rotterdam Erasmus MC Rotterdam, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Mamede: Doctors are often engaged in clinical encounters that are emotionally charged. Patients who feel anxious about their problems often respond emotionally in their interaction with their doctors. Most of these encounters fall within the limits of what is to be expected in clinical practice, but some patients behave in ways that make the doctor-patient interaction particularly distressing. Aggressive or disrespectful patients, frequent demanders, patients who don’t trust their doctors’ competence or ever-helpless patients are known, in the medical literature, as “difficult patients”. Doctors have reported to encounter these so-called “difficult patients” in around 15% of the outpatient consultations. As it might be expected, these patients’ behaviors provoke emotional reactions in doctors. The potential negative effect of these reactions on the doctor’s diagnostic accuracy has long been discussed in the medical literature. However, there was no empirical evidence that this happened. We conducted two studies to fill this gap. In the two studies, doctors diagnosed clinical cases that were exactly the same except for the patient’s behaviors. In the first study, we used complex and simple cases. Even though the cases were the same, doctors made 42% more mistakes in disruptive than in non-disruptive patients when the cases were complex, and 6% more mistakes when the cases were simple. In the second study, we used cases deemed to be at an intermediate level of complexity. Doctors made 20% more mistakes in difficult compared to neutral patients. These findings show that disruptive behaviors displayed by patients seem to affect doctors’ reasoning and induce them to make diagnostic errors. The findings of our second study suggest that disruptive behaviors “capture” the doctor’s attention at the expense of attention for the clinically relevant information. We came to this conclusion because when asked to recall the information from a case afterwards, doctors who were confronted with a difficult patient remember more information about the patient’s behaviors and less information of the clinically relevant symptoms than doctors confronted with the natural version of the same patient. Recall of information is considered a measure of the amount of attention given to such information.

What are the main findings? Dr. Ding: This study used data from the Sax Institute’s 45 and Up Study, a large Australia based cohort of adults aged 45 or older. We followed around 25,000 participants who were working at baseline (2006-2008) for an average of 3 years (follow-up in 2010). During the follow-up period, around 3,000 participants retired from the workforce. Participants were asked to report their health-related lifestyle behaviors, such as physical activity, smoking, and sleep time at both baseline and follow-up. We found that those who retired overall had significant improvement in their lifestyle as compared with those who did not, including more physical activity, less sitting time, and more sleep. Female smokers who retired were also more likely to have quit smoking.

MedicalResearch.com Interview with: [caption id="attachment_22702" align="alignleft" width="142"]Jonathan Shaw MD, FRACP, FRCP (UK), FAAHMS Associate Professor Domain Head, Population Health Research Baker IDI Heart and Diabetes Institute Melbourne VIC 3004 Dr. Jonathan Shaw[/caption] Jonathan Shaw MD, FRACP, FRCP (UK), FAAHMS Associate Professor Domain Head, Population Health Research Baker IDI Heart and Diabetes Institute Melbourne VIC 3004 MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Shaw: Over the last decade or so, there has been a lot of research connecting obstructive sleep apnoea with type 2 diabetes. They co-exist very frequently in the same individual, they are both much more common in overweight and obese people than in people of healthy weights, both improve with weight loss, and both are associated with other conditions such as hypertension and heart disease. In addition, there has been evidence that some of the key abnormalities occurring in sleep apnoea (in particular, fragmented sleep and intermittent low oxygen levels) may have a direct effect on glucose metabolism, and increase blood sugar levels. This led many people to suspect that untreated sleep apnoea might be one reason that type 2 diabetes is hard to control, and that treating sleep apnoea in people with type 2 diabetes would improve their blood sugar control. We, therefore, undertook a large trial among people with type 2 diabetes, and previously unrecognised sleep apnoea, in which participants were randomised to either a group receiving specific treatment for sleep apnoea (continuous positive airways pressure, or CPAP, therapy at night) or to a control group. Over the six months of the trial, we saw no benefit of CPAP therapy in regard to blood sugar control (as measured by HbA1c). Even when we looked at sub-groups with worse blood sugar control at the start or worse sleep apnoea or who did the best in terms of using CPAP every night, there was still no sign of benefit on blood sugar control. We did, however, see some other benefits of CPAP therapy, with less daytime sleepiness, improvements in quality of life and lower diastolic blood pressure.
Author Interviews, Hand Washing, Hospital Acquired, JAMA, University of Michigan / 15.03.2016

MedicalResearch.com Interview with: Lona Mody, MD, MS Veterans Affairs Healthcare System, Geriatric Research, Education, and Clinical Center Division of Geriatric and Palliative Medicine, University of Michigan Medical School, School of Public Health University of Michigan, Ann Arbor MedicalResearch.com: What is the background for this study? Dr. Mody: Hand hygiene is considered to be the most important strategy to prevent infections and spread of drug resistant organisms. Surprisingly, all strategies and efforts have predominantly involved healthcare workers and that too mainly in acute care hospitals.  We are now facing a tsunami of an aging population in our hospitals, post-acute care facilities and long-term care facilities.  Hand hygiene falls off when patients are hospitalized compared to when they are at home.  So, we were very interested, first, in hand colonization in older patients who have recently been transferred from the acute care hospital to a post-acute care (PAC) facility for rehabilitation or other medical care before fully returning home. We were also interested in evaluating whether these organisms persisted. MedicalResearch.com: What are the main findings? Dr. Mody: We recruited and followed 357 patients (54.9 percent female with an average age of 76 years). The dominant hands of patients were swabbed at baseline when they were first enrolled in a post-acute care facility, at day 14 and then monthly for up to 180 days or until discharge. The study found:
  • To our surprise, nearly one-quarter (86 of 357) of patients had at least one multi-drug resistant organism on their hands when they were transferred from the hospital to the post-acute care facility
  • During follow-up, 34.2 percent of patients’ hands (122 of 357) were colonized with a resistant organism and 10.1 percent of patients (36 of 357) newly acquired one or more resistant organisms.
  • Overall, 67.2 percent of colonized patients (82 of 122) remained colonized at discharge from PAC.

MedicalResearch.com Interview with: [caption id="attachment_22656" align="alignleft" width="200"]Michele Leardo Assistant Director Institute for Education & Social Policy New York University New York, NY 10012 Michele Leardo[/caption] Michele Leardo Assistant Director Institute for Education & Social Policy New York University New York, NY 10012 MedicalResearch.com: What is the background for this study? What are the main findings? Response: US school districts increasingly distribute annual fitness and body mass index (BMI) “report cards” to students and parents. Such personalized informational interventions have appeal in economics because they can inform parents about their children's obesity status at relatively low costs. Awareness of the weight status can lead to behavioral responses that can improve health. New York City public schools adopted Fitnessgram in 2007-2008, reporting each student’s BMI alongside categorical BMI designations. We examined how being classified as “overweight” for the previous academic year affected the students’ subsequent BMI and weight. Specifically, we compared female students whose BMI was close to their age-specific cutoff for being considered overweight with those whose BMI narrowly put them in the “healthy” category. We find that being labeled overweight had no beneficial effects on students’ subsequent BMI and weight.

What are the main findings? Dr. Filardo: While there are readily available, up-to-date data on the proportion of medical school applicants, graduates, and member of faculty women constitute, no similar information is routinely collected and shared about women’s participation in and leadership of medical research studies. The previous studies looking at this issue were conducted in 2004, and were limited to investigating the proportion of women among the first authors with MD degrees and with institutional affiliations in the United States or United Kingdom. The time was therefore ripe for an updated, rigorous, and comprehensive examination of first authorship in high impact medical journals. We examined female first authorship of original research articles published over the past 20 years in the 6 general medical journals with the highest impact factors: Annals of Internal Medicine (Annals), Archives of Internal Medicine (Archives), The BMJ (formerly the British Medical Journal), Journal of the American Medical Association, The Lancet, and New England Journal of Medicine (NEJM). After adjusting for differences over time and between journals related to different prioritisation of studies according to type, topic/specialty, country in which the research was conducted, or number of listed authors, we found that female first authorship increased overall from 27% in 1994 to 37% in 2014, but had plateaued – and in the cases of The BMJ and NEJM – declined in the last 5 years. Our results also revealed significant differences in female first authorship between journals.
Author Interviews, Cost of Health Care / 14.03.2016

MedicalResearch.com Interview with: Steffie Woolhandler MD, MPH, FACP and David U. Himmelstein MD, FACP CUNY School of Public Health at Hunter College MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Cadillac Tax aims to eventually eliminate tax subsides to employer-sponsored coverage.  When an employer provides health benefits to an employee, the employee pays no income or FICA tax on the value of those benefits, although the benefits are obviously part of the employee's compensation.  In other words, the taxpayers are currently picking up part of the employee's health insurance costs. Economists and politicians have been justifying the ACA's Cadillac Tax by portraying it as a "Robin Hood" tax that would take from the rich and give to the poor. That view of the Cadillac Tax is untrue.   We found that the main beneficiaries of the current tax subsidies to employer sponsored coverage are middle class families (defined by a family income between $39,000 and $100,000 in 2009 dollars) for whom the subsidies boost their effective income by about 5%.   These middle class people are the ones who would be most harmed when the Cadillac Tax kicks-in and curtails the current tax subsidies.
Abuse and Neglect, Autism, Depression / 14.03.2016

MedicalResearch.com Interview with: [caption id="attachment_22637" align="alignleft" width="112"]Dr. Rebecca A. Charlton PhD Senior Lecturer in Psychology; Undergraduate Admissions Tutor Department of Psychology Goldsmiths, University of London New Cross London, UK Dr. Rebecca Charlton[/caption] Dr. Rebecca A. Charlton PhD Senior Lecturer in Psychology; Undergraduate Admissions Tutor Department of Psychology Goldsmiths, University of London New Cross London, UK MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Charlton: Although Autism Spectrum Disorders are classified as developmental disorders, they last throughout life. Autism Spectrum Disorders were first identified in the 1940s, but it was only from the 1960s onwards that awareness of the condition began to increase. Initial research into Autism focused on the area of greatest need, i.e. childhood and education. Only now that those individuals first diagnosed with Autism are reaching old age are studies able to examine what happens in late-life. Although there are an increasing number of older adults with a diagnosis of Autism Spectrum Disorders, it is often difficult to identify individuals willing to participate in research. One alternative is to explore Autism traits in the general population, this is known as the Broad Autism Phenotype (BAP). These BAP traits occur in relatives of those with Autism and in the general population. By examining the BAP in community-dwelling older adults, we can begin to understand whether these traits confer additional risk to in ageing. MedicalResearch.com: What did you do in the study? What are the main findings? Dr. Charlton: Adults aged over 60 years old were recruited to take part in the study. They completed questionnaires reporting on presences of  Broad Autism Phenotype traits, executive functions (the ability to plan and organise behaviour), mood (depression and anxiety), and social support. Of the 66 individuals who participated, 20 individuals reported significant BAP traits – classified as the  Broad Autism Phenotype group. Individuals in the BAP group reported more problems with executive functions, higher rates of depression and anxiety, and less social support than those in the non-BAP group. Further analyses demonstrated that having  Broad Autism Phenotype traits was the factor that most explained presence of depression and anxiety symptoms among these older adults.

MedicalResearch.com Interview with: Ashley Bryce, NIHR PhD student Centre for Academic Primary Care, University of Bristol (first author) Dr Céire Costelloe NIHR Health Protection Research Unit in Healthcare associated infections and AMR, Imperial College London (senior author)  MedicalResearch.com: What is the background for this study? Response: Antimicrobial resistance is an internationally recognised threat to health. Previous antibiotic use has been shown to be a risk factor for antimicrobial resistance in adults. The contribution of primary healthcare is particularly important as this is where almost 80% of all antibiotics used within the health service are prescribed. Children receive a lot of primary healthcare services and, as such, receive a disproportionately high number of antibiotics compared with middle aged populations. Despite this, little research has been published describing the prevalence of bacterial resistance in children or the risk factors of importance in this group. MedicalResearch.com: What are the main findings? Response: Prevalence of resistance to commonly prescribed antibiotics in primary care in children with urinary tract infections caused by E coli is high, particularly in countries outside the OECD, where one possible explanation is the availability of antibiotics over the counter. This could render some antibiotics ineffective as first line treatments for urinary tract infection. Routine use of antibiotics in primary care contributes to antimicrobial resistance in children, which can persist for up to six months after treatment.

MedicalResearch.com Interview with: [caption id="attachment_22622" align="alignleft" width="153"]Dr George Thanassoulis MD MSc FRCPC McGill University Health Center and Research Institute Montreal, Quebec, Canada Dr. George Thanassoulis[/caption] Dr George Thanassoulis MD MSc FRCPC McGill University Health Center and Research Institute Montreal, Quebec, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Thanassoulis: Currently statins are recommended in most countries worldwide based on 10-yr risk of heart disease but because age is the best predictor of future heart disease this leads to many more older patients being eligible for statins at the expense of younger people.  This means that even young patients with higher levels of low-density cholesterol, a known cause of heart disease, are not eligible for statins until they are much older.  However, waiting for these individuals to become "old enough for treatment" permits their higher LDL  to continue to damage their arteries leading, in some cases, to advanced coronary disease at the time when statins are finally stated.  So we are missing an opportunity to effectively prevent heart disease. What our analysis shows is that we need to consider not just someone's risk of having a heart attack but also whether they would be expected to benefit from statins.  By integrating information from randomized trials we were able to show that there were over 9.5 million Americans who were at low risk (and not eligible for statin therapy) that would have the same absolute benefit as higher risk people who we currently treat.  These patients, as expected, were younger but had higher levels of LDL cholesterol.  We also showed that statin therapy in these individuals would avoid more than 250,000 cardiac events over 10 years.

MedicalResearch.com Interview with: [caption id="attachment_22034" align="alignleft" width="165"]Prof. Dr. Thomas Pilgrim Inselspital Berne Switzerland Dr. Thomas Pilgrim[/caption] Prof. Dr. Thomas Pilgrim Inselspital Berne Switzerland  Medical Research: What is the background for this study? Dr. Pilgrim: Long-term prognostic implications of different clinical manifestations of coronary artery disease are insufficiently understood at this time. A time variable pattern of recurrent events following PCI for STEMI, Non-STE-ACS or stable ischemic heart disease may have important implications for medical management and secondary prevention. Medical Research:? What are the main findings? Dr. Pilgrim: In our analysis, we found a differential in timing of ischemic events after PCI according to presentation with STEMI, NSTE-ACS, or stable ischemic heart disease, respectively. While patients with NSTE-ACS were at increased risk of death at any time after PCI as compared to patients with stable ischemic heart disease, patients with STEMI had an increased risk during the first 30 days after PCI but not thereafter compared to patients with stable ischemic heart disease.

MedicalResearch.com Interview with: Ida Behrens, MD and Heather Boyd PhD Department of Epidemiology Research Statens Serum Institut Copenhagen, Denmark MedicalResearch.com: What is the background for this study? Response: Over the past decade, we have begun to realize that a woman’s pregnancy experiences can be a predictor of her future health. Miscarriages, stillbirths and preterm deliveries have all been linked with an increased risk of later cardiovascular disease, as have hypertensive disorders of pregnancy (preeclampsia and gestational hypertension). Women with preeclampsia also have an increased risk of peripartum cardiomyopathy, a rare but serious condition that severely compromises heart function at the end of pregnancy or shortly after delivery. We were interested to find out whether women with preeclampsia or gestational hypertension during one or more pregnancies also had an increased risk of cardiomyopathy later in life. MedicalResearch.com: What are the main findings? Response: Using Danish national registers, we followed more than 1 million women with pregnancies between 1978 and 2011 – with an average follow-up of almost 18 years per woman – to see whether women with hypertensive disorders of pregnancy had increased rates of cardiomyopathy later in life, compared with women who only had normotensive pregnancies. We found that the women with hypertensive disorders of pregnancy had a two-fold increased risk of cardiomyopathy later in life. Interestingly, only half of this increase in risk could be linked to chronic hypertension, which is common among women who have previously had a hypertensive disorder of pregnancy. The remaining 50% was not associated with hypertension and could potentially be directly attributable to the woman’s pregnancy experience (or to an underlying cause common to both hypertensive disorders of pregnancy and cardiomyopathy). 
Author Interviews, Breast Cancer / 14.03.2016

MedicalResearch.com Interview with: [caption id="attachment_22492" align="alignleft" width="124"]Professor Nigel Bundred MD, FRCS Professor of Surgical Oncology Institute of Cancer Sciences University Hospital of South Manchester Dr. Nigel Bundred[/caption] Professor Nigel Bundred MD, FRCS Professor of Surgical Oncology Institute of Cancer Sciences University Hospital of South Manchester MedicalResearch.com: What is the background for this study? Dr. Bundred: HER-2 is a cancer-causing gene which is expressed in some cells by having more copies of the gene and predicts for early relapse and metastasis from the tumour. Despite this, even in the absence of anything other than local treatment, some 50% of patients still survive for five years without relapse. Herceptin was discovered and licensed for use in 2006 because it improved survival when given with chemotherapy after surgery, from 66% at five years to 90% at five years. The use of Herceptin and chemotherapy before surgery to shrink the tumour indicates that around 30% of patients have a complete pathological response with this treatment. Combination of dual anti-HER-2 therapies and  Neoadjuvant chemotherapy given for six months before surgery has been shown to increase pCR rate to 50% and a single study utilising the combination of pertuzumab and trastuzumab (two anti-HER-2 monoclonal antibodies) given for four months revealed a 16.8% pCR rate.

MedicalResearch.com Interview with: [caption id="attachment_22504" align="alignleft" width="135"]Pei-JieChen, Ph.D. Professor of Exercise Science, President of Shanghai University of Sport Dr. Pei JieChen[/caption] Pei-JieChen, Ph.D. Professor of Exercise Science, President of Shanghai University of Sport MedicalResearch: What is the background for this study? Dr. Pei-JieChen: Traditional Chinese exercises (such as Tai Chi, Qigong, Baduanjin) have been used for 2000 years with great contributions to human health, which are increasingly popular around the world. And traditional Chinese exercise is a low-risk, promising intervention that could be helpful for improving quality of life and depression in patients with cardiovascular diseases (CVDs).However, there appears to be no consensus agreement that traditional Chinese exercises (TCEs) could be effective for CVDs. Therefore, we performed a systematic review and meta-analysis to estimate the effectiveness of Traditional Chinese exercise for patients with CVDs. MedicalResearch: What are the main findings? Dr. Pei-JieChen: The pooling revealed that TCEs could decrease systolic blood pressure by 9.12 mmHg and diastolic blood pressure by 5.12 mmHg. Patients performing traditional Chinese exercises were also found superior compared with those in the control group in terms of triglyceride, six-minute walk test, Minnesota Living with Heart Failure Questionnaire results, SF-36 physical function, and Profile of Mood States depression.

MedicalResearch.com Interview with: Fanny Raguideau Evaluateur en pharmaco-épidémiologie Direction Scientifique et de la Stratégie Européenne Pôle Epidémiologie des produits de santé  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Retinal detachment (RD), including both exudative types often associated with systemic diseases that might be receiving antibiotics for related conditions as well as rhegmatogenous which require prompt surgical intervention to reduce the chance of irreversible severe vision loss, has an annual incidence rate of 1 per 10,000 in the general population. Rhegmatogenous is the most common type. Fluoroquinolones are one of the most commonly prescribed classes of antibiotics. Thanks to their broad-spectrum antibacterial coverage, they are effective in the treatment of a wide variety of community-acquired infections. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several studies have suggested that oral fluoroquinolone use increased the risk of Retinal detachment, however this association remains controversial. We conducted a nationwide self-matched design study to overcome limitations of previous studies. Our finding of a significant increased risk of  Retinal detachment, including both rhegmatogenous and exudative types, following use of oral fluoroquinolone strongly supports the existence of this association.

MedicalResearch.com Interview with: [caption id="attachment_22590" align="alignleft" width="93"]Hrishikesh Kale School of Pharmacy Virginia Commonwealth University Hrishikesh Kale[/caption] Hrishikesh Kale School of Pharmacy Virginia Commonwealth University MedicalResearch.com: What is the background for this study? What are the main findings? Response: The cost of cancer care in the United States is extremely high and escalating every year. Because of increased cost sharing, patients are paying higher out-of-pocket costs for their treatments. Along with high medical expenses, cancer survivors face problems such as loss of employment and reduced productivity. It has been well-established in the literature that because of high out-of-pocket costs, many cancer survivors forgo or delay medical care and mental health-related services and avoid filling prescriptions. This puts their physical and mental health at risk. A related issue is the growing number of cancer survivors in the U.S. As of January 2014, there were approximately 14.5 million cancer survivors in the U.S. By 2024, this number is expected to reach 19 million as a result of improved survival among patients with cancer along with an aging population. Therefore, we decided to investigate the prevalence and sources of financial problems reported by a nationally representative sample of cancer survivors from the 2011 Medical Expenditure Panel Survey. We also studied the impact of cancer-related financial burden on survivors’ health-related quality of life and psychological health.

MedicalResearch.com Interview with: [caption id="attachment_22605" align="alignleft" width="160"]Cyrus A. Raji, MD, PhD Resident in Diagnostic Radiology UCLA Health System Dr. Cyrus Raji[/caption] Cyrus A. Raji, MD, PhD Resident in Diagnostic Radiology UCLA Health System  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Raji: The purpose of this study was to investigate the relationship between caloric expenditure from leisure physical activities (15 different ones were assessed from walking to gardening to dancing to swimming etc.). Increased caloric expenditure from these physical activities were related to larger gray matter volumes in key brain areas for memory and learning (hippocampus, precuneus) that are also affected by Alzheimer's. These findings were demonstrated in 876 persons who had MRI scans and caloric expenditure assessed. Five years after the scan a subset of 326 persons from the larger group of 876 were followed cognitively and it was found that those with larger gray matter volumes associated with physical activity in the orbital frontal cortex and precuneus had a 2 fold reduction in the risk for cognitive decline to mild cognitive impairment and Alzheimer's dementia.

What are the main findings? Dr. Tuomanen: While investigating mechanisms of brain repair during infection in a mouse model system, we found that components from the surfaces of bacteria could traffic from the mother to the fetus. The bacterial components moved across the placenta and into the fetal brain. To our surprise, the fetal brain did not respond with neuronal death like we see in children with meningitis. Rather, fetal neurons proliferated. This response involved the innate immune system (TLR2) inducing the neuronal transcription factor, FoxG1, which is known to drive proliferation. The newly born neurons migrated appropriately to the cortical plate, the area on the surface of the fetal brain that forms the cortex, a major part of the adult brain. Although the neurons moved to the right place in the brain, there were too many and they crowded together in the cortex, changing the architecture of the brain. At birth, affected mice seemed to have no abnormalities. However, when we tested if this change in architecture would affect brain function after birth, mice were shown to progressively develop defects in learning, memory and other cognitive functions. This indicates there is a window during pregnancy where components of bacteria from the mother can change fetal brain architecture and subsequent postnatal behavior
Allergies, Author Interviews, Immunotherapy / 14.03.2016

MedicalResearch.com Interview with: Stacy L. Rosenberg, MD UPMC Montefiore Allergy and Immunology Fellow MedicalResearch.com: What is the background for this study? Dr. Rosenberg: Allergy shots or allergen immunotherapy (AIT) is an effective therapy for allergic rhinoconjunctivitis (hay fever).  Low adherence has been a significant barrier, whereas rush immunotherapy to environmental allergens provides rapid build-up and offers quicker efficacy, which may improve adherence.  However, there have been concerns for increased risk of systemic reactions with rush protocols.  We describe a new protocol for modified rush AIT that offers quicker build-up towards a maintenance dose with improved safety and lower risk of systemic reactions.  We also hypothesize that there are specific characteristics that distinguish patients who develop systemic reactions in the setting of modified environmental rush immunotherapy (MERIT). MedicalResearch.com: What are the main findings? Dr. Rosenberg: Overall, MERIT has a good safety profile.  A subset of patients did develop systemic reactions, which were mild.  Lower BMI was associated with systemic reactions and there was a trend between history of urticaria (hives) and younger age with development of systemic reactions.  Significantly more patients with systemic reactions had allergen extracts containing cat, dust mite, and weed pollen.  Neither gender, asthma, nor anaphylaxis history were associated with an increased risk of systemic reactions.
Author Interviews, Nutrition / 12.03.2016

MedicalResearch.com Interview with: [caption id="attachment_22593" align="alignleft" width="200"]Dr.Noelle Noyes Dr.Noelle Noyes[/caption] Noelle R Noyes PhD Department of Clinical Sciences Colorado State University, Fort Collins MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study is the increasing concern about antibiotic resistant infections, and what we can do as a society to help minimize the development and spread of antibiotic resistance. Antibiotic resistance is a natural and ancient phenomenon in bacteria, but we can do things to bacterial populations to increase the amount of resistant bacteria and to promote the spread of resistant bacteria. It behooves us to try to identify specific practices that might be contributing to increases in antibiotic resistance, and to understand how we can change them to minimize risk. Towards this end, our study utilized new methods for investigating the ecology of antibiotic resistance throughout the process of beef production, from the time cattle enter feedlots through slaughter to the beef products that we eventually buy in the grocery store. Livestock production is thought to play a role in antibiotic resistance, although we have very little understanding of how important this role may be compared to other sectors like human hospitals, municipal wastewater treatment, daycare facilities, etc… We wanted to use new DNA sequence-based methods to try to get a high-level picture of what was happening with antibiotic resistance genes in feedlots and slaughterhouses. This high-level picture could then help us to understand how important cattle production may be in the overall ecology of antibiotic resistance, including the food chain and wider environment.

MedicalResearch.com Interview with: Yanning Wang, MS Statistical Research Coordinator Department of Pathology, Immunology and Laboratory Medicine Department of Health Outcomes and Policy University of Florida College of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: A number of new stimulant medications have been approved for attention deficit/hyperactivity disorder (ADHD) treatment in the past decade. The expansion of this market, along with the increase in ADHD diagnosis, provides greater availability of these drugs. This has raised public health concerns about potential non-medical use of prescription stimulants. Our study analyzed data from the National Monitoring of Adolescent Prescription Stimulants Study, which recruited and surveyed youth aged 10 to 18 years from entertainment venues in 10 US cities. We found that 6.8% of youth (750 out of 11,048) used prescription stimulants in the past 30 days. Among those 750 youth, more than half reported some type of non-medical use, and using someone else’s medication was the most common form (88.4 %). We investigated the difference between two subgroups of non-medical users: youth who only used stimulants non-medically, and those who had a prescription and reported non-medical use in the past 30 days. We found youth who only used stimulants non-medically at higher rate of using other substances and more likely to have close friends who have tried other drugs.

MedicalResearch.com Interview with: [caption id="attachment_22580" align="alignleft" width="166"]Naveen Pokala, MD Division of Urology University of Missouri Columbia, MO 65212 Dr.Naveen Pokala[/caption] Naveen Pokala, MD Division of Urology University of Missouri Columbia, MO 65212 MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Pokala: The main purpose of the study was to determine survival outcome following salvage prostatectomy in men that fail radiation therapy. Radiation and surgery are the main modalities utilized to treat localized prostate cancer. When patients fail radiation treatment, traditionally, only hormonal treatment was offered. With refinements in surgical techniques, a select few of these patients that have recurrence after radiation may benefit with salvage surgery. Salvage prostatectomy is a complex procedure because prior radiation makes this procedure tenuous, but this procedure is offered in most major tertiary medical centers.

Lockwood, MD Member of of the March of Dimes Board of Trustees Dean at Morsani College of Medicine Senior Vice President, USF Health and Professor of Obstetrics & Gynecology, and Public Health The University of South Florida Dr. Charles Lockwood[/caption] Charles J. Lockwood, MD Member of of the March of Dimes Board of Trustees Dean at Morsani College of Medicine Senior Vice President, USF Health and Professor of Obstetrics & Gynecology, and Public Health The University of South Florida  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Lockwood: There remain questions about the utility of vaginal progesterone therapy in asymptomatic women with singleton gestations at risk for preterm birth. The OPPTIMUM study investigators conducted a double-blind, randomized, placebo-controlled trial of vaginal progesterone delivered via a pessary releasing 200 mg per day (n=618) vs. placebo (n=610) from around 22 to 34 weeks gestation among women at high risk for prematurity on the basis of a characteristic history and/or the presence of cervicovaginal fetal fibronectin or a cervical length less than 25 mm in length on transvaginal ultrasound.  The primary endpoints were fetal death or preterm birth before 34 weeks (obstetrical outcome), or a composite of neonatal mortality or morbidities (neonatal outcome).  The authors found that progesterone had no significant impact on either primary endpoint, with an adjusted OR of 0·86, 95% CI: 0·61-1·22 for obstetrical outcomes and an OR of 0·62, 95% CI:0·38-1·03 for neonatal outcomes.

MedicalResearch.com Interview with: [caption id="attachment_22572" align="alignleft" width="120"]Chairman and Surgeon-in-Chief Department of Surgery Saint Barnabas Medical Center Professor of Surgery New Jersey Medical School Rutgers University Dr. Ronald Chamberlain[/caption] Ronald S. Chamberlain, MD, MPA, FACS Chairman and Surgeon-in-Chief Department of Surgery Saint Barnabas Medical Center Professor of Surgery New Jersey Medical School Rutgers University MedicalResearch.com: What is the background for this study? Dr. Chamberlain:  With the rapidly growing arthritic, aging, and obese population, total hip replacement (THR) has become the most commonly performed orthopedic procedure in the United States (US).  The Affordable Care Act signed by President Barack Obama imposed financial penalties for excess readmissions following certain procedures and diagnoses. While the initial program aimed to reduce readmissions for heart failure, pneumonia, and acute myocardial infarction (AMI), the program expanded to include THR in 2015. With current research estimating a 10%, 30-day readmission rate following a total or partial hip replacement, this study sought to identify factors associated with readmission and to create a scale which could reliably stratify preoperative readmission risk.

Dr. Unger: The rate at which trials are positive has previously been examined, and the relationship between trial results and publication rates in the context of publication bias has also been studied. But the comparative scientific impact of positive vs negative clinical trials using citation data has not been investigated We used the phase III trial database of SWOG, a major national cooperative clinical trials group, in combination with its trial publication database and citation data from Google Scholar, to compare the scientific impact of positive vs negative phase III cancer clinical treatment trials.
Author Interviews, Heart Disease / 11.03.2016

MedicalResearch.com Interview with: Malin Inghammar, MD, PhD Department of Infectious Diseases Skåne University Hospital, Lund Sweden  MedicalResearch.com: What is the background for this study? Dr. Inghammar: Fluoroquinolones are a class of antibiotics with a widespread use in the treatment of common infections. Agents of this drug are generally well tolerated and have few side effects but in some people fluoroquinolones can prolong the QT-interval. QT-prolongation is a sort of electrical disturbance in the heart that can, in rare instances, lead to potentially life-threatening arrhythmia. Some drugs are well known to cause QT-prolongation and to be able to trigger arrhythmia. Fluoroquinolones however, have only weak effect on the QT-time. There have been a few previous studies published reporting an increased risk. Some of these, compared fluoroquinolone treated patients with people who were not treated with antibiotics at all. In these studies, it can’t be ruled out that the infection itself, rather than the antibiotic treatment could have influenced the risk of arrhythmia. In some other previous studies, there have been indications that the patients receiving fluoroquinolones were of poorer general health than the comparison group, which could also have affected the results. Therefore it is not clear if oral fluoroquinolone treatment leads to an increased risk of serious cardiac arrhythmia in an everyday clinical situation.
Author Interviews, Pain Research, Stanford / 11.03.2016

MedicalResearch.com Interview with: [caption id="attachment_22554" align="alignleft" width="200"]Eric Sun, MD/PhD Instructor Department of Anesthesiology, Perioperative and Pain Medicine Stanford University Dr. Eric Sun[/caption] Eric Sun, MD/PhD Instructor Department of Anesthesiology, Perioperative and Pain Medicine Stanford University MedicalResearch.com: What is the background for this study?  Dr. Sun: Epidural steroid injections are frequently used to treat chronic low back pain.  While previous studies have shown they are effective at improving symptoms, whether they reduce spending is unknown.  These concerns are particularly salient because insurers are worried that epidural steroid injections are being overused. MedicalResearch.com: What are the main findings? Dr. Sun: Overall, we find that epidural steroid injections were associated with decreases in spending ranging from five to fifteen percent, depending on the specific indication.  These differences were largely driven by decreases in outpatient spending (e.g., spending on outpatient physician visits).
