Prof. Paul E O'Brien Centre for Obesity Research and Education Monash University Melbourne, AustraliaMedicalResearch.com Interview with: Prof. Paul E O'Brien Centre for Obesity Research and Education Monash University Melbourne, Australia   MedicalResearch.com: What are the main findings of the study? Prof. O'Brien: Using a randomised trial format we compared the diabetes status at two years after a program of multidisciplinary diabetes care (MDC) alone or with the addition of a Lap-Band procedure in 50 people who were overweight (BMI 25-30) and with diabetes. 52% of the Lap-Band group had remission of their diabetes as measured by glucose tolerance testing compared to 8% in the multidisciplinary diabetes care group. The Lap-Band procedures were performed as outpatients with a 2-3 hr length of stay. There were no perioperative adverse events. The surgical group had lost a mean of 11.5kg in weight. The incremental cost effectiveness ratio (ICER) for remission of diabetes was AUD $20,700. (more…)

Mr. Thamara Perera FRCS Consultant Surgeon - Multi Organ Retrieval and Liver Transplant Liver Transplant - University Hospitals Birmingham NHS Foundation Trust Queen Elizabeth Hospital, Queen Elizabeth Medical Centre, Birmingham, UKMedicalResearch.com Interview with: Mr. Thamara Perera FRCS Consultant Surgeon - Multi Organ Retrieval and Liver Transplant Liver Transplant - University Hospitals Birmingham NHS Foundation Trust, Queen Elizabeth Hospital, Queen Elizabeth Medical Centre, Birmingham, UK MedicalResearch.com: What are the main findings of the study? Answer: In this study we compared the basic energy metabolism of liver grafts obtained from conventional and widely practiced form of organ donation, the donation after brain death (DBD) donors, and recently revived form of organ donation called donation after circulatory death (DCD) donors. To introduce a background to this study - DCD liver grafts are perceived as marginal liver grafts, owing to the basic differences surrounding the organ donation. DCD organs suffer a period of warm ischemia from the time of treatment withdrawal in a potential donor up until the organs are actually recovered and preservation is initiated. Although the DCD liver grafts have supplemented the donor organ pool, the initial and short-term results following liver transplantation are comparatively poor and these differences are attributable to the donor warm ischemia. However there were no studies in the literature examining the energy status of DCD liver grafts and our study is the first such study. (more…)

Takehiro Sugiyama, MD, MSHS, PhD Project Director, Diabetes Policy Planning Office Management and Planning Bureau Fellow, Department of Diabetes, Endocrinology and Metabolism National Center for Global Health and Medicine Shinjuku-ku, Tokyo JapanMedicalResearch.com Interview with: Takehiro Sugiyama, MD, MSHS, PhD Project Director, Diabetes Policy Planning Office Management and Planning Bureau Fellow, Department of Diabetes, Endocrinology and Metabolism National Center for Global Health and Medicine Shinjuku-ku, Tokyo Japan MedicalResearch.com: What are the main findings of the study? Dr. Sugiyama: In the US nationally representative sample from the National Health and Nutrition Examination Survey 1999-2010, we found that statin users in 2009-2010 eat 9.6% more calories and 14.4% more fat than statin users in 1999-2000. These increases were not observed in statin non-users; the trends of caloric and fat intake were statistically different between statin users and non-users. In 1999-2000, caloric and fat intake was significantly less for statin users compared with non-users, but the difference between the groups because smaller as time went by and there was no statistical difference in 2009-2010. Body mass index increased more rapidly for statin users compared to non-users. (more…)

Tara Lagu MD PhD Assistant Professor of Medicine Tufts University School of MedicineMedicalResearch.com Interview with: Tara Lagu MD PhD Assistant Professor of Medicine Tufts University School of Medicine   MedicalResearch.com: What are the main findings of the study? Dr. Lagu: We found that use of mechanical ventilation in patients 65 and older is increasing rapidly. If current rates of increase continue, we expect that by 2020 there will be more than 600,000 hospitalizations per year that involve mechanical ventilation. This is a doubling in 20 years (2001-2020), and represents demand that could easily exceed the capacity of the US critical care system. We also found that increase in use among patients with dementia is 4 times faster than those without dementia. This is important because dementia is a terminal illness, and use of mechanical ventilation in patients with end-stage dementia is associated with poor 30-day and 1-year outcomes. (more…)

N. Chan, MBChB MD FHKAM FRCP Professor Juliana Chan is Professor of Medicine and Therapeutics, Director, Hong Kong Institute of Diabetes and Obesity and International Diabetes Federation Centre of Education at the Chinese University of Hong Kong, Prince of Wales Hospital and Chief Executive Officer of Asia Diabetes Foundation Hong Kong. MedicalResearch.com: What are the main findings of the study? Dr. Chan: In this 1-year randomized study, we asked the question whether type 2 diabetic patients receiving team-based integrated care augmented by information technology would further improve in their glycemic control if given additional peer support through the telephone. All patients underwent comprehensive risk assessment guided by the web-based JADE portal which generated personalized risk report with attained treatment targets and decision support. After 1 year, all patients improved significantly in all risk factors including A1c with improved treatment adherence, self efficacy and psychological wellbeing. Although the peer support group did not further improve in A1c, short-stay hospitalization rates were substantially reduced by 50% , especially amongst those with emotional distress. These patients accounted for 20% of the intervention group, in whom peer support further reduced psychological distress and treatment non-adherence. (more…)

MedicalResearch.com Interview with: Alice Dragomir, MSc, PhD Assistant Professor, Urology/Surgery, McGill University Scientist, RI-MUHC MedicalResearch.com: What are the main findings of the study? Authors’ response: Our study demonstrates that for eligible patients, active surveillance could offer not only the known clinical advantages from the patient’s perspective, but also economic benefits from the health care system’s perspective. At the national level, the cost savings of an annual cohort of incident prostate cancers managed with active surveillance over a first year and 5 years of follow-up could be substantial. These are estimated at $96 million. (more…)

MedicalResearch.com Interview Invitation Karin J. H. Verweij, PhD Department of Developmental Psychology and EMGO Institute for Health and Care Research,  VU University Amsterdam, the Netherlands MedicalResearch.com: What are the main findings of the study? Dr. Verweij: We performed a twin study using over 10,000 adult Australian twins to determine the relative importance of genetic and environmental influences on individual differences in non-suicidal self-injury (NSSI) and suicidal ideation and their covariation. We found that individuals that report self-harm are approximately eight times more likely to also report suicidal ideation. Results from the bivariate genetic model indicated that the substantial correlation between non-suicidal self-injury and suicidal ideation (r=0.49 for males and 0.61 for females) is largely explained by overlapping genetic factors: 62% and 76% for males and females, respectively. Overlapping residual influences, including nonshared environmental influences and measurement error, also explain part of the covariance between the two traits. These findings suggest that the two behaviors share similar biological underpinnings. (more…)

Fonarow MD Director, Ahmanson-UCLA Cardiomyopathy Center Professor, Department of Medicine Associate Chief, Cardiology David Geffen School of Medicine Los Angeles, CA MedicalResearch.com: What are the main findings of the study? Dr. Fonarow: This study examined data from hospitals that have adopted the American Heart Association/ American Stroke Association’s national quality initiative, Target: Stroke, which aims to increase the number of stroke patients treated with clot-busting drugs for ischemic stroke within 60 minutes or less after hospital arrival.  Initiated nationwide in 2010, Target: Stroke provided 10 key strategies as well as tools to facilitate timely tPA administration, as well as additional approaches to improve stroke care and outcome. Data from 71,169 tPA-treated stroke patients at 1,030 hospitals participating in Target: Stroke were analyzed to compared the time to treatment and incidence of complications before implementation, from 2003 to 2009, to the post-implementation years, from 2010 to 2013. This study found that the percentage of patients treated within the recommended timeframe increased from less than one-third before Target: Stroke to more than half afterwards. The Target: Stroke program goal of 50 percent or more of patients having door-to-needle times within 60 minutes was successfully achieved. In addition, the average time to treatment dropped by 15 minutes, from 74 to 59 minutes. Faster treatment was associated with lower rates of complications, including death. Before Target: Stroke, 9.9% of stroke patients died in the hospital, compared to 8.3% of patients treated after the initiative started, a difference which was statistically significant. In addition, patients treated by Target: Stroke strategies were less likely to develop the complication of symptomatic intracranial hemorrhage. (more…)

Rosenzweig, MD, PhD Director, Primary Immunodeficiency Clinic (PID-C) Head of the Infectious Diseases Susceptibility Unit at the Laboratory of Host Defenses, National Institutes of Allergy and Infectious Diseases National Institutes of Health Bethesda, MD, 20892 MedicalResearch.com: What are the main findings of the study? Dr. Rosenzweig: We diagnosed a disease called CDG-IIb in two siblings with severe development issues and very low levels of immunoglobulins, which include infection-fighting antibodies. These children were referred to the NIAID Primary Immunodeficiency Clinic through the NIH Undiagnosed Diseases Program. CDG-IIb is an extremely rare congenital disorder of glycosylation (CDG), with only one other case reported. The genetic defect of the disease disrupts glycosylation, the process for attaching and trimming sugars from proteins. Almost 50% of our proteins have sugars attached, and these are called glycoproteins. They include immunoglobulins and also some viral glycoproteins that are made when cells are infected by a virus. The spread of some viruses, including HIV and influenza, depend on viral glycoproteins in order to infect additional cells and form viral protective shields. We found that this type of virus was less able to replicate, infect other cells, or create adequate protective shields in CDG-IIb patient cells because of the glycosylation defect. In comparison, adenovirus, poliovirus, and vaccinia virus, which either do not rely on glycosylation or do not form protective glycoprotein shields, replicated normally when added to both CDG-IIb and healthy cells.

MedicalResearch.com Interview with: Dr Mark Bolland, PhD Bone and Joint Research Group, Department of Medicine University of Auckland, Auckland, New Zealand MedicalResearch.com: What are the main findings of the study? Prof. Bolland: In a meta-analysis of 20 randomized clinical trials, there was no effect of vitamin D with or without calcium on falls.  In a trial sequential analysis of these trials, the effect estimate for vitamin D with or without calcium on falls lay within the futility boundary, providing reliable evidence that vitamin D supplementation does not alter the relative risk of falls by ≥15% and suggesting that future trials that are similar in design to current trials are unlikely to change that conclusion.

MedicalResearch.com Interview with: Susan Jaglal, PhD Senior Scientist Toronto Rehabilitation Institute University of Toronto, Toronto, Ontario MedicalResearch.com: What are the main findings of the study? Dr. Jaglal: Bone Mineral Density (BMD) tests are used to both diagnose osteoporosis and assess and individual’s risk of fracture. While the tests play an important role in bone health, they are sometimes ordered inappropriately. For example, while women age 40-44 are typically not at risk of fragility fracture or in need of Bone Mineral Density testing, these individuals received almost half the Bone Mineral Density tests performed in Ontario in 2007/2008. Policy changes have been made in recent years in an effort to curb unnecessary testing of low risk individuals in both the United States and Canada. Policy efforts in Ontario included a 2008 fee schedule change that limited repeated testing among low-risk patients and included a new fee code for a “baseline” tests. Patients were limited to 1 baseline test in their lifetime. The goal of the present study was to determine the impact of this fee schedule change on Bone Mineral Density testing rates. The study was based on an analysis of provincial administrative data including physician billings, hospital discharges, and emergency department visits. Results demonstrated that while fee schedule changes were associated with a decrease in BMD testing rates, the decreases affected both low and high-risk patients. Most decreases were seen in testing rates of low-risk women. However, the associated decrease in testing among high-risk patients (e.g., those over 65 or with a recent fracture) is concerning, as high-risk patients benefit from screening and monitoring of Bone Mineral Density.

Dr. Li-Ching Lee: This population-based case-control study in young children provides evidence that prenatal selective serotonin reuptake inhibitor (SSRI) use may be a risk factor for autism and other developmental delays (DD). Among boys, prenatal SSRI exposure was nearly 3 times as likely in children with autism spectrum disorder (ASD) relative to children with typical development; the strongest association occurred with first-trimester exposure. Exposure was also elevated among boys with DD and was strongest in the third trimester. (more…)

MedicalResearch.com Interview with: Rustam Al-Shahi Salman Professor of clinical neurology and MRC senior clinical fellow, University of Edinburgh Honorary consultant neurologist, NHS Lothian upcoming JAMA publication:MedicalResearch.com Interview with: Rustam Al-Shahi Salman Professor of clinical neurology and MRC senior clinical fellow University of Edinburgh Honorary consultant neurologist, NHS Lothian MedicalResearch.com: What are the main findings of the study? Prof. Al-Shahi Salman: Patients with arteriovenous malformations (abnormal connection between arteries and veins) in the brain that have not ruptured had a lower risk of stroke or death for up to 12 years if they received conservative management of the condition compared to an interventional  treatment. Interventional treatment for brain arteriovenous malformations (bAVMs) with procedures such as neurosurgical excision, endovascular embolization, or stereotactic radiosurgery can be used alone or in combination to attempt to obliterate bAVMs. Because interventions may have complications and the untreated clinical course of unruptured bAVMs can be benign, some patients choose conservative management (no intervention). Guidelines have endorsed both intervention and conservative management for unruptured brain arteriovenous malformations. Whether conservative management is superior to interventional treatment for unruptured bAVMs is uncertain because of the lack of long-term experience, according to background information in the article.

MedicalResearch.com Interview with: Rodrigo Pinto Pedrosa, MD, PhD Sleep and Heart Laboratory, Pronto Socorro Cardiológico de Pernambuco Pernambuclo, Brazil MedicalResearch.com: What are the main findings of the study? Dr. Pedrosa: Perimenopause is associated with increased cardiovascular risk. This study evaluated the association between obstructive sleep apnea (OSA) and arterial stiffness and hypertension in perimenopausal women. OSA (apnea-hypopnea index: ≥5 events/hour) and moderate/severe OSA (apnea-hypopnea index: ≥15 events/h) were diagnosed in 111 (40.1%) and 31 (11.1%) of women, respectively.  Women with moderate/severe obstructive sleep apnea  had a higher prevalence of hypertension, were prescribed more medications for hypertension, had higher awake blood pressure,  nocturnal blood pressure,  diastolic blood pressure, as well as higher arterial stiffness (pulse wave velocity: 11.5 [10.1 to 12.3] vs 9.5 [8.6 to 10.8] m/s, p<0.001) than women without obstructive sleep apnea, respectively. Oxygen desaturation index during the night was independently associated with 24h arterial blood pressure and with arterial stiffness. (more…)

Sessler, M.D. Michael Cudahy Professor and Chair, Department of Outcomes Research Cleveland Clinic, Cleveland, OH MedicalResearch.com: What are the main findings of the study? Dr. Sessler: Free fatty acids, arachidonic acid and linoleic acid, and their metabolites hydroxyeicosatetraenoic acids (5-HETE, 11-HETE, 12-HETE, and 15-HETE) were 1.8 to 5.7-fold greater in 37 patients with adenocarcinoma versus 111 patients without cancer (all P<0.001). Areas under the receiver operating characteristics (ROC) curve were significantly greater than 0.50 discriminating lung cancer patients and controls for all biomarkers and phospholipids, and ranged between 0.69 and 0.82 (all P<0.001) for lung cancer patients versus controls. Arachidonic acid, linoleic acid, and 15-HETE showed sensitivity and specificity >0.70 at the best cutpoint. Concentrations of free fatty acids and their metabolites were similar in 18 squamous-cell carcinoma patients and 54 non-cancer controls. (more…)

Kurian, M.D., M.Sc. Assistant Professor of Medicine and of Health Research and Policy Divisions of Oncology and Epidemiology and James M. Ford, MD Associate Professor of Medicine Pediatrics and Genetics, Division of Oncology, Stanford University School of MedicineJames M. Ford, MD Associate Professor of Medicine Pediatrics and Genetics, Division of Oncology, Stanford University School of Medicine MedicalResearch.com: What are the main findings of the study? Answer: We found that 11% of women who met standard clinical criteria for BRCA1 and BRCA2 (BRCA1/2) mutation testing, yet had tested negative, actually carried an actionable mutation in another cancer-related gene.  We found that patients were highly motivated to learn about their genetic test results and new recommendations for cancer risk reduction.  Over a short follow-up period, colonoscopy screening resulted in early detection of a tubular adenoma in a patient found to have a high-risk MLH1 mutation, and thus the multiple-gene testing in our study has likely prevented at least one cancer to date.  We conclude that multiple-gene sequencing can benefit appropriately selected patients.

Dr. Patton: Although there has been wide acceptance that the teens are a time when emotional problems are common, views have been polarized about their significance. Some have viewed these problems are usual for this phase of life with little significance for later life mental health; others have argued that early psychiatric intervention was essential given the risks of ongoing disorders. In this sample almost two thirds of girls and a third of boys had an episode of emotional troubles (anxiety and depression) at a level that would concern a family physician. For those where the episode were brief lasting weeks to months, recovery without further later life episodes was common. In contrast those with persistent (longer than 6 months) or recurrent emotional problems during the teens had a high likelihood of similar problems with depression and anxiety in their twenties. In general these emotional problems persisted more in females than in males. (more…)

Nurnberger, Jr., M.D., Ph.D. Professor of Psychiatry Joyce and Iver Small Professor of Psychiatry Indiana University School of Medicine   MedicalResearch.com: What are the main findings of this study? Dr. Nurnberger: The main findings of the study are the biological pathways identified to be associated with bipolar disorder, including those involved in hormonal regulation, calcium channels, second messenger systems, and glutamate signaling. Gene expression studies implicated neuronal development pathways as well. These findings highlight the role of certain neurobiological processes that have been considered in prior hypotheses of bipolar disorder. They underline a role for calcium signaling, which has only been clearly implicated in the genetics of bipolar disorder in recent years. They also feature hormonal processes such as the hypothalamic-pituitary-adrenal axis, which has been known to be involved in stress responses, but has not been prominent in many recent theories of the pathogenesis of bipolar disorder.

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

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

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