MedicalResearch.com Interview with: Marwan Badri MBChB, MRCP Cardiovascular disease fellow Lankenau Medical Center Wynnewood Pa Medical Research : What is the background for this study? Dr. Badri: Recent years witnessed increased emphasis of the role of clinical guidelines in cardiovascular care. Physicians are encouraged to practice within the framework of major society guidelines to deliver better, more cost-effective patient care. It is therefore vital that the recommendations in these guidelines are applicable to most of the patient population. Since some clinical trials have been shown in the past to unfavorably exclude women, racial minorities and elderly patients, we conducted this study to see if the clinical trials used to form the American College of Cardiology/American Heart Association adequately represent these patient groups.

Stewart Agras, M.D. Professor of Psychiatry Emeritus Stanford University School of MedicineMedicalResearch.com Interview with: Stewart Agras, M.D. Professor of Psychiatry Emeritus Stanford University School of Medicine MedicalResearch: What was the study about? Dr. Agras: Family-based treatment (FBT) has been shown to be more effective than individual psychotherapy for the treatment of adolescent anorexia nervosa. This treatment focuses on helping the family to re-feed their child. The question posed in this study was whether Family-based treatment would have any advantages over Systemic family therapy (SyFT) focusing on family interactions that may affect the maintenance of the disorder. The participants were 164 adolescents with anorexia nervosa and their families – one of the largest studies of its type.

Clinical Pharmacy University of Tennessee Health Science Center Memphis, TN 38163 Medical Research: What are the main findings of the study? Dr. Hong: Use of GDDP (generic drug discount programs) increased to 23.1% in 2010 from 3.6% of patients receiving any prescription drugs in 2007. Generic drug discount programs were more valued among the elderly, sicker and uninsured populations. The lower use of Generic drug discount programs among racial/ethnic minorities observed when the program was deployed no longer existed when the program matured.

Prof Mika Kivimäki PhD Department of Epidemiology and Public Health, University College London, London, UK Hjelt Institute, Medical Faculty, University of Helsinki, Helsinki, FinlandMedicalResearch.com Interview with: Prof Mika Kivimäki PhD Department of Epidemiology and Public Health, University College London, London, UK Hjelt Institute, Medical Faculty, University of Helsinki, Helsinki, Finland Medical Research: What are the main findings of the study? Prof. Kivimäki: In our study, we pooled published and unpublished data from 222 120 men and women from the USA, Europe, Japan, and Australia. Of them, 4963 individuals developed type 2 diabetes during the mean follow-up of 7.6 years. This is the largest study to date on this topic. In an analysis stratified by socioeconomic status, the association between long working hours and diabetes was evident in the low socioeconomic status group, but was null in the high socioeconomic status group. The association in the low socioeconomic status group did not change after taking into account age, sex, obesity, physical activity, and shift working. So, the association was very robust. In brief, the main finding of our meta-analysis is that the link between longer working hours and type 2 diabetes was apparent only in individuals in the low socioeconomic status groups.

Dr. Courtet: Depressed outpatients who are beginning the treatment with a SSRI at higher dose than recommended present an increased risk (x2) of worsening of suicidal ideation during the first 6 weeks of treatment. This is consistent with the study by Miller et al published in the same journal few weeks ago, reporting a double risk of suicide attempt in young subjects (<24 yrs) who are begun an SSRI at higher dose than recommended. Our results showed that the increased suicide risk with the high dose of SSRI is not restricted to youngsters and is independent of the severity of the depression.

MedicalResearch.com Interview with: Todd C. Lee, MD, MPH Division of General Internal Medicine and Infectious Diseases Department of Medicine, McGill University Health Centre McGill Centre for Quality Improvement, Montreal, Quebec, Canada Medical Research: What are the main findings of the study? Dr. Lee: We found that in our cross-sectional study of six inpatient units in five hospitals that, in general, only 11% of patients were wearing lower body garments despite the fact that probably 55% of them could have been doing so.  The remainder were wearing open backed gowns.  When specifically asked, the majority of these patients would like to have been afforded the opportunity to wear more dignified attire and the patients were surprised that they were allowed to do so.

Kovesdy, MD Professor of Medicine University of Tennessee Health Science Center Chief of Nephrology Memphis Veterans Affairs Medical CentMedicalResearch.com: Interview Invitation Dr. Csaba P. Kovesdy, MD Professor of Medicine University of Tennessee Health Science Center Chief of Nephrology Memphis Veterans Affairs Medical Center Medical Research: What are the main findings of the study? Dr. Kovesdy: We applied the structure of a clinical trial of hypertension management to our cohort of >600,000 patients with prevalent Chronic Kidney Disease (CKD). We first identified patients with baseline uncontrolled hypertension (using the definition applied by the SPRINT trial), then isolated the ones who had a decline in their baseline systolic blood pressure to two different levels (<120 and 120-139 mmHg) in response to a concomitant increase in prescribed antihypertensives, similar to what would happen in a trial examining two different systolic blood pressure targets. We then matched patients in the two groups to end up with identical baseline characteristics, similar to a randomized trial. When we examined the all-cause mortality of these two groups, we found that the group with follow-up systolic blood pressure of <120 had a 70% higher mortality.

Dr. Gershon: Within a large real world population of people with COPD, those who initiated combination long-acting beta-agonists (LABA) and inhaled corticosteroids (ICS) were less likely to die or be hospitalized for COPD than those who initiated LABA alone. Further those who initiated LABA/ICS combination therapy did not appear to have more pneumonia or osteoporotic fractures – side effects that have been associated with ICS use—than those initiating LABA alone. A second interesting finding was that people with a co-diagnosis of asthma experienced a greater incremental benefit of LABA/ICS over LABA than people without a co-diagnosis of asthma. Finally, we found that people who were not also taking an inhaled long-acting anticholinergic medication experienced a greater incremental benefit of LABA/ICS over LABA than people who were.

MedicalResearch.com Interview  Dongyi (Tony) Du, MD, PhD Division of Epidemiology FDA/CDRH/OSB Medical Research: What are the main findings of the study? Dr. Du: The risk for death on the date of surgery was 60% higher for recipients of mechanical aortic valves than recipients of bioprosthetic aortic valves (OR, 1.61 [95%CI, 1.27-2.04; P < .001]; risk ratio [RR], 1.60). The risk difference decreased to 16% during the 30 days after the date of surgery (OR, 1.18 [95%CI, 1.09-1.28; P < .001]; RR, 1.16). The risk for operative mortality was 19% higher for recipients of mechanical compared with bioprosthetic valves (OR, 1.21 [95%CI, 1.13-1.30; P < .001]; RR, 1.19). The number needed to treat with mechanical valves to observe 1 additional death on the surgery date was 290; to observe 1 additional death within 30 days of surgery, 121.

MedicalResearch.com Interview : Iben Marie Miller, MD Department of Dermatology Roskilde Hospital, Roskilde Department of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark Medical Research: What are the main findings of the study? Dr. Miller: Using a cross-sectional design based on data from a Hidradenitis Suppurativa (HS) group recruited from the hospital (32 individuals), an HS group recruited from the general population (326 individuals) and 14,851 individuals without Hidradenitis Suppurativa, we investigated a possible association of Hidradenitis Suppurativa and the metabolic syndrome. We found that the HS groups had 2 to 4 times odds of having the metabolic syndrome when compared to individuals without HS leaving Hidradenitis Suppurativa patients at a high cardiovascular risk. Furthermore, we found that the odds were higher for the HS group from the hospital in comparison to the Hidradenitis Suppurativa group from the general population.

Dr. Mason: We examined 49,408 women enrolled in the Nurses' Health Study II to see if those who had experienced PTSD symptoms at some point in their lives were more likely than those without PTSD symptoms to meet the criteria for food addiction, a measure of perceived dependence on food. We found that the 8% of women with the most lifetime PTSD symptoms were about 2.7 times as likely to meet the criteria for food addiction as women with no lifetime PTSD symptoms. This translates to an elevation in food addiction prevalence from about 6% among women with no PTSD symptoms to about 16% in women with the most PTSD symptoms.

Darren J. Malinoski, MD, FACS Assistant Chief of Surgery – Research and Education Chief, Section of Surgical Critical Care Portland VA Medical Center Associate Professor of Surgery Oregon Health & Science University Portland, OR 97207MedicalResearch.com Interview with: Darren J. Malinoski, MD, FACS Assistant Chief of Surgery – Research and Education Chief, Section of Surgical Critical Care Portland VA Medical Center Associate Professor of Surgery Oregon Health & Science University Portland, OR 97207 Medical Research: What are the main findings of the study?  Dr. Malinoski: Our two main findings are that the status of the DMG Bundle prior to organ recovery, at the end of the OPO donor management process, is the most predictive of the number of organs that will be transplanted per expanded criteria donor (ECD) and that the absolute increase in the number of individual DMG elements achieved over time also appears to be relevant.  Taken together, these two findings suggest that the number of organs that will be transplantable from each donor is not necessarily predetermined by their age, comorbidities, and pre-neurologic death condition, but that active critical care management has the ability to affect outcomes and reassessing each donor’s condition over time is necessary.

Aner Tal, PhD Food and Brand Lab Department of Applied Economics and Management Cornell University, Ithaca, New YorkMedicalResearch.com Interview with: Aner Tal, PhD Food and Brand Lab Department of Applied Economics and Management Cornell University, Ithaca, New York Medical Research: What are the main findings of the study? Dr. Tal: Some TV programs might lead people to eat twice as much as other programs. “We find that if you’re watching an action movie while snacking your mouth will see more action too!” says Aner Tal, Ph.D. lead author on the new article just published in the Journal of the American Medical Association: Internal Medicine. “In other words, the more distracting the program is the more you will eat.” In the study 94 undergraduates snacked on M&Ms, cookies, carrots and grapes while watching 20 minutes of television programming. A third of the participants watched a segment of the action movie The Island, a third watched a segment from the talk show, the Charlie Rose Show, and a third watched the same segment from The Island without sound. “People who were watching The Island ate almost twice as many snacks – 98% more than those watching the talk show!” says co-author Brian Wansink, author of Slim by Design (forthcoming) and Professor and Director of the Cornell Food and Brand Lab. “Even those watching “The Island” without sound ate 36% more.” People watching the more distracting content also consumed more calories, with 354 calories consumed by those watching The Island (314 calories with no sound) compared to 215 calories consumed by those watching the Charlie Rose Show. “More stimulating programs that are fast paced, include many camera cuts, really draw you in and distract you from what you are eating. They can make you eat more because you're paying less attention to how much you are putting in your mouth,” explains Tal. Because of this, programs that engage viewers more might wind up being worse for their diets.

Dr. Carrier: Venous thromboembolism (VTE), comprised of deep vein thrombosis and pulmonary embolism, is the third leading cause of cardiovascular death. There are many anticoagulant treatments available but there is little guidance about which treatment is most effective and safe. This systematic review and network meta-analysis evaluated eight different treatment options for acute Venous thromboembolism.  Forty-five trials were included in the analysis and there were no significant differences in clinical or safety outcomes associated with most treatment options when compared to the combination of LMWH-VKA..

Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, AustraliaMedicalResearch.com Interview with: Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, Australia Medical Research: What are the main findings of the study? Dr. Doyle: From collectively pooling data from five large trials carried out around the world over the past 20 years, we know that magnesium sulfate given under strict medical protocols in hospital to women threatening to deliver preterm reduces the risk of cerebral  palsy in their children in early childhood.  Following  from this knowledge, magnesium sulfate is now given routinely to women, under strict medical conditions, who are threatening to deliver very early in Australia, and in other parts of the world, to try to prevent cerebral palsy in their child.  What we do not know is if magnesium sulfate used this way has any longer-term effects on the brain or on other important outcomes. One of the initial studies that contributed to the overall evidence about cerebral palsy was carried out in Australia and New Zealand and completed more than 10 years ago.  Over 1000 women and their babies were enrolled in that study and although the rate of cerebral palsy was not substantially reduced by magnesium sulfate in our study, we showed that there were fewer children at 2 years of age who were not walking in the group whose mothers were given magnesium compared with those whose mothers were given placebo.  With this knowledge, and given the unknown longer-term benefits or risks, we re-evaluated the children from our study at school-age, between 6-11 years of age.  We thoroughly evaluated their brain function, including movement and co-ordination, thinking ability, behaviour, and school progress, as well as general health and well-being.  The basic message from our longer-term study is that magnesium sulfate, as used in our trial, does not have any substantial benefits or harms on brain or cognitive function, or any other outcome at school age.

Dr. Koton: Based on data on 14,357 participants in the Atherosclerosis Risk in Communities (ARIC) study who were free of stroke when the study began in 1987 and followed until the end of 2011, we found a 24 percent overall decline in first-time strokes in each of the last two decades and a 20 percent overall drop per decade in deaths after stroke. The results were similar across race and gender, but varied by age: the decline in stroke risk was concentrated mainly in the over-65 set, while the decrease in stroke-related deaths was primarily found among those under age 65.

Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine, Atlanta, GeorgiaMedicalResearch.com Interview with: Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine,  Atlanta, Georgia Medical Research: What are the main findings of the study? Dr. Lynch:
  • Since 2006, the VA has been systematically using teleretinal screening of patients with diabetes to screen for retinopathy in the Primary Care Clinics. Under this program, 90% of veterans with diabetes are evaluated on a regular basis. A number of patients who are screened have findings that warrant a face-to-face ophthalmic exam. No information exists on the effect of such a program on medical center resources.
  • 1,935 patients  underwent teleretinal screening through the Atlanta VA over a 6 month period.  We reviewed the charts of the 465 (24%) of the patients who were referred for a face to face exam in the Eye Clinic.
  • Data was collected for these patients to determine the reasons for referral, the accuracy of the teleretinal interpretation, the resources needed in the Eye Clinic of the Medical Center to evaluate and care for the referred patients over a two year period and possible barriers to patient care.
  • Of the 465 patients referred for an exam, 260 (55.9%) actually came in for an exam. Community notes were available for an additional 66 patients. Information was available for 326 (70.1%) of the referred patients.
  • The most common referring diagnoses were nonmacular diabetic retinopathy (43.2% of referrals), nerve related issues (30.8%), lens or media opacity (19.1%), age-related macular degeneration (12.9%) and diabetic macular edema (5.6%).
  • 16.9% of the referred patients had 2 or more concurrent problems that put them at high risk for visual loss.
  • The percentage agreement between teleretinal screening and the ophthalmic exam was high: 90.4%. Overall sensitivity was 73.6%. The detection of diabetic macular edema had the lowest sensitivity.
  • A visually significant condition was detected for the first time through teleretinal screening for 142 of the patients examined (43.6%).
  • The resource burden to care for referred patients was substantial.
  • 36% of patients required 3 or more visits over the ensuing 2 year period.
  • The treatment of diabetic macular edema had the highest resource use involving on average 5 clinic visits, 6 diagnostic procedures and 2 surgical procedures
  • The most common non-refractive diagnostic procedures were visual fields and optical coherence tomography.
  • The average cost to care for the referred patients (in Medicare dollars) in work RVUs alone was approximately $1,000 per patient. The cost to care for a patient with diabetic macular edema was $2673.36.

MedicalResearch.com Interview with: Rena Zuo, BA MD Candidate at Duke University School of Medicine and Edward W. Cowen, MD, MHSc Senior Clinician Head, Dermatology Consultation Service Dermatology Branch Center for Cancer Research National Cancer Institute National Institutes of Health MedicalResearch: What are the main findings of the study?
 Answer: Chronic graft-vs-host disease (cGVHD) is a debilitating multisystem disease that occurs in patients receiving allogeneic hematopoietic stem cell transplantations as treatment for hematologic disorders. Although the diverse clinical presentations of cGVHD frequently mimic other autoimmune diseases such as Sjögren syndrome and systemic sclerosis, and low-titer antibodies are commonly found in patients with cGVHD, the exact pathogenesis and role of autoimmunity in cGVHD are incompletely understood. Our study is the first to characterize and identify risk factors associated with the development of two uncommon autoimmune phenomena, specifically alopecia areata and vitiligo, in the setting of cGVHD. Laboratory markers, including 11 antibodies, transplant-related factors, and other cGVHD systemic manifestations were analyzed. Several particularly interesting results were found:
  1. Among 282 patients with cGVHD, 15 demonstrated vitiligo (14 of 282; 4.9%) and/or alopecia areata (2 of 282; 0.7%).
  2. Female donor and female donor to male recipient sex mismatch, in particular, are significantly associated with the development of vitiligo and/or alopecia areata.
  3. Positive anti-cardiolipin (ACA) IgG was also significantly associated with development of vitiligo and/or alopecia areata.

  • The quality of the US diet improved modestly from 1999 to 2010, but the dietary quality of US population remains far from optimal and huge room exists for further improvements.
  • More than half of the improvement in diet quality was due to a large reduction in consumption of trans fat.
  • he improvement in dietary quality was greater among persons with higher socioeconomic status and healthier body weight, thus disparities that existed in 1999 increased over the next decade.

Dr. Johnston:
  • Our findings represent the first meta-analysis using advanced epidemiological methods to summarize popular branded diets for weight loss, trials having been investigated using randomized trial methodology.
  • Among the 48 original RCTs included in our NMA, low to moderate quality evidence showed that both low-carbohydrate and low-fat diets were associated with an approximate 8 kg weight loss at 6 months when compared to no diet. Approximately 1-2 kg of this effect was lost by 12-months.
  • Although statistical differences existed among several of the diet macronutrient classes, the differences were small and unlikely to be important to those seeking to lose weight.
  • Similarly, our results showed that although there are statistically significant differences between some of the brand named diets, these differences are small and not likely patient important.
  • In terms of potential effect modifiers, behavioural support was significant at 6-months (enhancing weight-loss by 3.23 kg) and exercise was significant at 12-months (enhancing weight loss by 2.13 kg)
  • Regarding our sensitivity analyses, Differences in weight loss were not clinically important based on risk of bias, missing data, baseline weight, gender, and those with and without specific health conditions
  • Overall, our findings suggest that patients may choose, among those associated with the largest weight loss, the diet that gives them the least challenges with adherence.

Massimo Imazio. MD, FESC Dipartimento di Cardiologia/Cardiology Department Maria Vittoria Hospital and University of Torino Torino, ItaliaMedicalResearch.com Interview with: Massimo Imazio on behalf of the COPPS-2 Investigators Massimo Imazio. MD, FESC Dipartimento di Cardiologia/Cardiology Department Maria Vittoria Hospital and University of Torino Torino, Italia Medical Research: What is the background for this investigation? Dr. Imazio: Post-pericardiotomy syndrome, post-operative atrial fibrillation (AF), and post-operative effusions may be responsible for increased morbidity and healthcare costs after cardiac surgery. Postoperative use of colchicine prevented these complications in a single trial (the COPPS trial published on EHJ in 2010). Here all events occurred within 3 months and colchicine was given after cardiac surgery starting from postoperative day 3 for 1 month. However most postoperative AF events are reported in the first 3 days and thus pre-treatment with colchicine may give better outcomes. Thus we performed the COPPS-2 giving colchicine 48 to 72 hours before surgery for 1 month without a loading dose and weight adjusted doses (i.e. 0.5 mg twice daily for patients >70kg or 0.5 mg once for patients <70Kg) in order to improve patients compliance.The Colchicine for Prevention of the Post-pericardiotomy Syndrome and post-operative atrial fibrillation (COPPS-2 trial) is an investigator-initiated, double-blind, placebo-controlled, randomized clinical trial. A total of 360 consecutive candidates for cardiac surgery, 180 for each arm, were enrolled in 11 Italian centers between March 2012 and March 2014. Main exclusion criteria were absence of sinus rhythm at enrollment, cardiac transplantation, and contraindications to .
