Kirstine Kobberøe Søgaard, MD Department of Clinical Epidemiology, Aarhus University Hospital, DenmarkMedicalResearch.com Interview with: Kirstine Kobberøe Søgaard, MD Department of Clinical Epidemiology, Aarhus University Hospital, Denmark Medical Research: What are the main findings of the study? Response: Venous thromboembolism (VTE) is mainly considered an acute illness with a high mortality right after the event, whereas knowledge on the impact on long-term survival has been sparse. In our study, we used nationwide data on VTE since 1977, and included 128,223 patients with VTE and 640,760 individuals from the general population without a VTE diagnosis. We had complete follow-up data on individual patient level and were able to link information from other hospital admissions and thereby obtain each patient’s entire hospital history, as well as death statistics with specific cause of death. We confirmed the high mortality immediately after the thromboembolic event, but more interestingly, we found that mortality remained increased during the entire follow-up period of 30 years, with venous thromboembolism as an important cause of death among patients with deep venous thrombosis and/or pulmonary embolism.

Dr. Pibarot: The optimal timing of aortic valve replacement (AVR) in asymptomatic patients with severe aortic stenosis (AS) remains a matter of debates. Both the American and European guidelines recommend AVR for patients with severe AS who present with symptoms or left ventricular (LV) systolic dysfunction. However, patients with aortic stenosis are often older, less physically active and have more comorbidities, which make the assessment of AS-related symptoms challenging and unreliable. In this study by Capoulade et al, plasma levels of brain natriuretic peptide (BNP) were obtained in 157 patients with severe asymptomatic aortic stenosis and preserved LV ejection fraction at peak of exercise-stress echocardiography. Patients in the upper (>95 pg/ml) and mid (>45 pg/ml) tertiles of exercise BNP respectively had a 5- and 3- fold increase in the risk of events (i.e. AVR or death) compared to those in the lower tertile. Similar results were obtained in the subset of patients with low resting BNP. (more…)

Jean Marc Regimbeau MedicalResearch.com Interview with : Pr. Jean-Marc Regimbeau Service de Chirurgie Digestive Oncologique et Métabolique, CHU d’Amiens   Medical Research : What are the main findings of the study? Answer: In our study we found that the absence of postoperative administration of amoxicillin plus clavulanic acid did not improve the occurrence of postoperative infections in patients with mild or moderate acute calculous cholecystitis. The bile cultures were pathogen free in 60.9% of case. Moreover we show that less than 2 percent of the overall population presented a major complication defined according to the Clavien Dindo Classification (Clavien score ≥3a). After cholecystectomy the readmission rate was 6%. (more…)

Dr. Koegelenberg: The aim of this study was to evaluate the efficacy of combining varenicline and a nicotine patch versus varenicline alone as an aid to smoking cessation in a double-blind study design in a larger group and with a longer assessment period than has been studied to date. It was found that the combination treatment was associated with a statistically significant and clinically important higher continuous abstinence rate at 12 weeks (55.4% vs. 40.9%; P=.007) and 24 weeks (49.0% vs. 32.6%; P=.004), and point prevalence abstinence rate at 6 months (65.1% vs. 46.7%; P=.002). The present study was not adequately powered to fully assess safety and tolerability endpoints, but the results suggest that adverse events were balanced across treatment arms, except for mild skin reactions that were more frequently observed in the nicotine patch group (14.4% vs. 7.8%, P=.03).

Pachucki, PhD Senior Scientist, Mongan Institute for Health Policy Affiliated Faculty, MGHfC Division of General Academic Pediatrics Instructor in Medicine and Pediatrics, Harvard Medical School Boston, MA 02114MedicalResearch:.com Interview with: Mark C. Pachucki, PhD Senior Scientist, Mongan Institute for Health Policy Affiliated Faculty, MGHfC Division of General Academic Pediatrics Instructor in Medicine and Pediatrics, Harvard Medical School Boston, MA 02114 MedicalResearch: What are the main findings of the study? Dr. Pachucki: We found that in in one-child families, having an obese parent made a child about twice as likely to be obese themselves. However, in two-child families, a child’s obesity status was more strongly related with their sibling than with their parent. Even more interesting, in the case of the younger sibling, the parent’s obesity status was not related with that child’s obesity status at all. These findings matter because family members are primary sources of social influence for children – understanding how health status is correlated within a family gives us a better foothold on possible intervention strategies.

Wolfson Medical Center Sackler Faculty of Medicine, Tel Aviv University and Tel Aviv Medical  Center, Israel Medical Research: What are the main findings of the study? Prof. Jakubowicz: In type 2 diabetes there is a deficit of post-meal insulin secretion (from pancreatic beta-cells) that  contributes to an exaggerated elevation in blood glucose. In this study we  found that consumption of whey protein shortly before breakfast augmented  GLP-1 (a gut hormone that stimulates insulin secretion) enhancing insulin response and lowering glucose excursions after breakfast.

MedicalResearch.com Interview with: David Olds, Ph.D. Professor of Pediatrics and Director Prevention Research Center for Family and Child Health University of Colorado Department of Pediatrics Aurora, Colorado   80045MedicalResearch.com Interview with: David Olds, Ph.D. Professor of Pediatrics and Director Prevention Research Center for Family and Child Health University of Colorado Department of Pediatrics Aurora, Colorado   80045 Medical Research: What are the main findings of the study? Dr. Olds: We’ve conducted a randomized controlled trial of a program of nurse home visiting for low-income women with no previous live firths during pregnancy and the first two years of the child’s life, with randomization of participants beginning in 1990. In our most recent follow-up of mothers and children in Memphis, those who received nurse-visitation were less likely to have died over a 2-decade period following the child’s birth than those in the control group.  Death among mothers and children in these age ranges in the US is rare and extraordinarily important for what it tells us about the health of the population studied in this trial. For children, the reduction in death was present for preventable causes, that is, sudden infant death syndrome, injuries, and homicide.  All of the child deaths for preventable causes were in the control group, for whom the rate was 1.6%.  None of the nurse-visited children died of preventable causes. The reductions in maternal mortality were found for two nurse-visited groups combined for this report: one received prenatal and newborn visitation and a second received visitation during pregnancy and through child age two.  Overall, mothers assigned to the control group were nearly 3 times more likely to die than those assigned to the two nurse-visited conditions.  The relative reduction in maternal mortality was particularly pronounced for deaths linked to maternal behaviors -- suicide, drug overdose, injuries, and homicide; for these external causes of death, 1.7% of the mothers in the control group had died, compared to 0.2% of those visited by nurses.

Dr. Soo Chan Lee: Mucor circinelloides strain isolated from recalled Chobani yogurt was found to be the most virulent subspecies M. circinelloides forma circinelloides that is commonly associated with human infections. When mice were infected with this fungus through the tail-vein, 80% mortality was observed 5 days post infection. When mice were fed with spores, the fungus survived passage through the GI tract as many as 10 days, indicating the fungus can colonize to cause infections.  Whole genome sequence analysis revealed the possibility that this fungus could produce harmful secondary metabolites that are unknown in this fungal species.

MedicalResearch.com Interview with:Vincenza Spallone MD PhD Endocrinology and Neurology Department of Systems Medicine Tor Vergata University, Rome, Italy Vincenza Spallone MD PhD Endocrinology and Neurology Department of Systems Medicine Tor Vergata University, Rome, Italy   Medical Research: What are the main findings of the study? Dr. Spallone:To investigate a possible relationship between painful diabetic polyneuropathy (PDPN) and the circadian pattern of blood pressure (BP), we performed ambulatory blood pressure monitoring in 113 diabetic patients with PDPN, with painless diabetic polyneuropathy (DPN) and without DPN. In addition, we evaluated neuropathic pain, sleep, risk for obstructive sleep apnoea (OSA), autonomic function, and in a subgroup of patients, depressive symptoms. The main finding was that patients with painful diabetic polyneuropathy displayed impaired nocturnal fall in BP compared to those without neuropathy, and higher nocturnal systolic blood pressure than the other two groups. Although the day-night change (∆) in blood pressure failed to reach a significant difference between painful diabetic polyneuropathy and DPN groups, nondipping (the loss of nocturnal fall in systolic BP) was more strictly associated with painful diabetic polyneuropathy than DPN and in multivariate analysis, including comorbidities and most potential confounders, neuropathic pain was an independent determinant of ∆ BP and nocturnal systolic blood pressure. In summary, we showed a novel association of peripheral diabetic neuropathic pain with nondipping and higher systolic nocturnal blood pressure, which was not entirely explained through pain dependent sleep problems or other pain- or diabetes-related comorbidities, like CAN, OSA and depression.

Lukas Schwingshackl, MSc Department of Nutritional Sciences University of Vienna Vienna, AUSTRIAMedicalResearch.com: Interview with: Lukas Schwingshackl, MSc Department of Nutritional Sciences University of Vienna Vienna, AUSTRIA Medical Research: What are the main findings of the study? Lukas Schwingshackl: The results of the present meta-analyses showed that, in patients with established diabetes, aerobic training might be more effective in reducing glycosylated haemoglobin and fasting glucose when compared with resistance training. Combined aerobic and resistance training was more powerful in reducing glycosylated haemoglobin compared with aerobic training, and more effective in reducing glycosylated haemoglobin, fasting glucose and tricylglycerols when compared with resistance training. However, these results could not be confirmed when only low risk of bias studies were included. (more…)

MedicalResearch.com Interview with: Dr. Liang He Department of Anesthesiology Yan’an Hospital of Kunming City, kunming, 650051, China MedicalResearch: What are the main findings of this study? Dr. He: We evaluated the prognostic value of plasma heart-type fatty acid binding protein (H-FABP) in patients with acute pulmonary embolism (PE) with the guidelines of acute PE of European Society Cardiology (ESC). We found that higher H-FABP level (above 6 or 7 ng/ml) was associated with an increased of 30-d mortality and complicated clinical events, from six studies of 85 articles included. H-FABP has the potential to be a novel prognostic marker that can help optimize patient management strategies and risk-stratification algorithms in the population of patients with acute pulmonary embolism. However, few studies had been specifically designed to answer our research questions. (more…)

Des Jarlais PhD Director, International Research Core, Center for Drug Use and HIV Research Research Fellow, NDRI Director of Research, Baron Edmond de Rothschild Chemical Dependency Institute, Beth Israel Medical Center Professor of Epidemiology, Department of Epidemiology and Population Health, Albert Einstein College of Medicine Medical Research: What are the main findings of the study? Dr. Des Jarlais: HIV infection among non-injecting users of heroin and cocaine doubled doubled over the last several decades, from 7% to 14%. Herpes simplex virus type 2 (HSV-2) increases both susceptibility to and transmissibility of HIV. We examined HSV-2 infection among non-injecting heroin and cocaine user over the same time period using stored serum samples. HSV-2 infection was strongly related to HIV infection, and both increased over time. We calculated population attributable risk percentages (PAR%) to estimate the extent to which HSV-2 was driving increased HIV infection. HSV-2 infection was responsible for approximately half of the increase in HIV infection (more…)

Dr. Agardh: In this study, we stratify the risk of celiac disease among children according to their HLA genotype and country of residence. We confirm that HLA-DQ2/2 genotype is the major risk factor for early celiac disease, but also show how the risk differs between the participating countries despite of sharing similar HLA risk. This points to the direction of an interaction between HLA and the environment that eventually lead to an autoimmune response in genetic susceptible children. (more…)

MedicalResearch.com Interview with: Lorenzo Loffredo, MD and Francesco Violi, MD Department of Internal Medicine and Medical Specialties Sapienza University of Rome, Rome, Italy; MedicalResearch: What are the main findings of the study? Answer: Dark chocolate is rich of polyphenols; these natural substances exert antioxidant properties and, through an increase of nitric oxide, dilate arteries. Our research group applied this effect to enhance blood flow in a very common disease, the peripheral arterial disease. This disease is characterized by reduced blood flow to the limbs. There are not any drugs that improve this blood flow, but dark chocolate could. Our study suggest that dark chocolate, and only dark chocolate, could reduce oxidative stress and improve blood flow and walking autonomy in patients with peripheral arterial disease. We observed no effect on blood flow, oxidative stress and on walking autonomy in PAD patients after milk chocolate assumption. This lack of effect was probably due to the low concentration of polyphenols in milk chocolate. (more…)

MedicalResearch.com Interview with: Tamara Haegerich, PhD Deputy Associate Director for Science Division of Unintentional Injury Prevention CDC - National Center for Injury Prevention and ControlMedicalResearch.com Interview with: Tamara Haegerich, PhD Deputy Associate Director for Science Division of Unintentional Injury Prevention CDC - National Center for Injury Prevention and Control MedicalResearch: What are the main findings of the study? Dr. Haegerich: In the first three decades of life, more people in the US die from injuries and violence than from any other cause. Approximately 60% of fatal injuries are unintentional (for example, from motor vehicle crashes, drug overdose, and falls), 20% are due to suicide, and 20% are due to homicide. Injuries and violence have been linked to a wide range of physical, mental health, and reproductive health problems, and chronic diseases. They take an enormous economic toll, including the cost of medical care and lost productivity. Importantly, injuries and violence are preventable through education, behavior change, policy, engineering, and environmental supports. For example, laws that promote the use of seat belts and child safety seats, and prevent drunk driving, can reduce motor-vehicle-related injuries. Early childhood home visitation, school-based programs, and therapeutic foster care are examples of evidence-based approaches to preventing violence. Improving proper prescribing of painkillers and access to treatment for substance misuse could prevent prescription drug overdoses. Improvements are possible by framing injuries and violence as preventable, identifying interventions that are cost-effective and based on research, providing information to decision makers, and strengthening the capacity of the health care system.

Dr. Tisdale: Using a nonmyeloablative allogeneic HLA-match peripheral blood stem cell transplantation strategy aimed at tolerance induction, we were able to revert the phenotype in 26 of 30 adult patients with severe sickle cell disease ranging in age from 16 to 65 years. In contrast to standard transplantation strategies which rely on high doses of chemo and/or radiotherapy after which the entire bone marrow and blood system is replaced by that of the donor, our patients had a mixture of their own and that of their donor. This procedure was well tolerated, with no non-relapse mortality, and led to complete replacement of red blood cells by that of the donor in successfully engrafted patients. This replacement resulted in decreases in pain, pain medication usage, hospitalizations, and improvements in organ function. (more…)
