Paul Kimmel, M.D. Division of Kidney, Urologic and Hematologic Diseases National Institute of Diabetes and Digestive and Kidney Diseases at the National Institutes of Health Professor Division of Renal Diseases and Hypertension The George Washington UniversityMedicalResearch.com Interview with: Paul Kimmel, M.D. Division of Kidney, Urologic and Hematologic Diseases National Institute of Diabetes and Digestive and Kidney Diseases at the National Institutes of Health Professor Division of Renal Diseases and Hypertension The George Washington University Medical Research:   What are the main findings of the review? Dr. Kimmel: AKI (Acute Kidney Injury) and CKD (Chronic Kidney Disease), two syndromes approached separately in medical school  curricula  as well as in the clinical arena are inextricably intertwined.  They should be taught as a combined entity, culminating in progressive loss of renal function necessitating renal replacement therapy (dialysis or transplantation). The two syndromes increase risk for cardiovascular disease and diminished quality of life as well.  Preventive and therapeutic strategies should be directed at the combined entity.

Iftikhar J. Kullo, MD Division of Cardiovascular Diseases Mayo Clinic Rochester, MNMedicalResearch.com Interview with: Iftikhar J. Kullo, MD Division of Cardiovascular Diseases Mayo Clinic Rochester, MN   Medical Research: What are the main findings of the study? Dr. Kullo: The main findings of the study are: 1) Family history of stroke or heart attack is associated with presence of significant narrowing (greater than 70%) of the carotid arteries. These are the arteries that supply blood to the brain and narrowing or blockage of these arteries is associated with increased risk of stroke; 2) Having a sibling history of stroke or heart attack was more strongly associated with narrowing of the carotid artery than having a parent with such history; 3) The greater number of relatives with history of stroke or heart attack, the greater the odds of having narrowing in one of the carotid arteries.

Dr. Kirsty Boyd Programme theme head (Clinical Communication) Honorary Clinical Senior Lecturer Primary Palliative Care Research Group Division of Community Health Sciences: General Practice University of EdinburghMedicalResearch.com Interview with: Dr. Kirsty Boyd Programme theme head (Clinical Communication) Honorary Clinical Senior Lecturer Primary Palliative Care Research Group Division of Community Health Sciences: General Practice University of Edinburgh Medical Research: What do we know already about people with ‘multimorbidity’? Dr. Boyd: We know that an increasing number of patients have multiple life-limiting illnesses or progressively deteriorating health due to several long term conditions or general frailty. Caring for them well poses major challenges and they are often hospitalised in the last year of life. They do not fit well into illness and healthcare models that focus on single conditions. Understanding the experiences of patients and their family caregivers is vital to inform improvements in best supportive care and palliative care. We wanted to build on care models for integrated care of people with long term conditions and consider the needs of those at risk of dying with multiple conditions in more detail.

MedicalResearch.com Interview with: Jeffrey Allen Kline Vice Chair of Research Department of Emergency Medicine MedicalResearch.com Interview with: Jeffrey Allen Kline Vice Chair of Research Department of Emergency Medicine Indiana University Health Medical Research: What are the main findings of this study? Dr. Kline: We believe that clinicians use information from their patients’ faces to make decisions about diagnostic testing. This is particularly relevant in emergency medicine, where the clinicians make decisions rapidly with limited information. We videotaped patients’ faces who had chest pain and dyspnea and used the most well-known facial scoring system to assess their facial expression variability in response to seeing visual stimuli. We found that patients who ultimately had emergent problems tended to hold their faces in a neutral position and be less likely to show the expression of surprise. The investigators were not surprised at this, but we did find that patients with emergent problems also tended to have less negative affect as well as less positive affect. In other words, patients who were sickest even tended to frown less than patients with no medical problem.

Alejandro Arrieta, PhD Assistant Professor Department of Health Policy and Management Florida International UniversityMedicalResearch.com Interview with: Alejandro Arrieta, PhD Assistant Professor Department of Health Policy and Management Florida International University Medical Research: What are the main findings of the study? Dr. Arrieta: We found that it makes business sense for insurance companies to reimburse patients for the cost of blood pressure monitors that they can use at home. In just the first year, we estimate that insurance companies can produce returns that range from $0.85 to $3.75 per dollar invested in blood pressure monitors provided to their members.

Dr. Bangalore: Our objective was to evaluate whether non-fasting LDL has similar prognostic significance as that of the conventionally measured fasting LDL values. We found that in an analysis of over 16,000 patients from the National Health and Nutrition Examination Survey that the non-fasting LDL values had similar prognostic significance as that of fasting LDL values for the prediction of long term (up to 14 years) death or cardiovascular death, thus questioning the traditional practice of insisting that patients fast prior to blood draw for a lipid panel. This was also true for other components of the lipid panel including the triglycerides and total cholesterol.

Dr. Dregan: Our study showed that chronic inflammation was associated with increased risk of developing cardiovascular disease, specifically type II diabetes and coronary heart disease. The risk of cardiovascular disease increased with the severity of inflammatory disorders. In addition, inflammation also increased the risk of multiple morbidity (two or more cardiovascular diseases).

Dr Nils Muhlert Wellcome Trust ISSF Research Fellow School of Psychology Cardiff UniversityMedicalResearch.com Interview with: Dr Nils Muhlert Wellcome Trust ISSF Research Fellow School of Psychology Cardiff University Medical Research: What are the main findings of the study? Dr. Muhlert: Decision making impairments are known to occur in people with multiple sclerosis (MS), and are important, given they can contribute to employment status, treatment compliance and function in everyday life. Studies by Kleeberg, Simioni and others have demonstrated that decision-making impairments can occur early in the course of multiple sclerosis and get worse as the disease progresses. Questions however remain over whether these impairments are linked to more general cognitive difficulties, differences between multiple sclerosis subtypes, and their relationship with MRI changes. We assessed decision-making and examined MRI changes in a relatively large sample of people with multiple sclerosis (N = 105) and healthy controls (N = 43). All participants performed the Cambridge Gambling Task, which independently measures risk-taking, impulsivity, deliberation and risk adjustment, and underwent an MRI scan including T1-weighted and diffusion MRI sequences. We demonstrate that people with multiple sclerosis experience difficulties with risk adjustment (gauging risk and adapting accordingly) and in the speed of making decisions but not in impulsivity. These problems were seen in those classified as having cognitive impairment and those not (i.e. cognitively unimpaired). We found that decision-making impairments were twice as common in people with relapsing-remitting and primary progressive MS than healthy controls, and almost four times as common in people with secondary progressive multiple sclerosis. In addition, decision making impairments in multiple sclerosis were linked to MRI changes in regions previously linked to decision-making in other conditions, including fronto-striatal and hippocampal regions. These findings offer insight into the precise decision-making difficulties experienced by people with multiple sclerosis, the relative prevalences in different subtypes of the disease and the pathological processes that may underlie them.

MedicalResearch.com Interview with: dr_Eric RavussinEric Ravussin, Ph.D., Boyd Professor Director Nutrition Obesity Research Center Douglas L. Gordon Chair in Diabetes and Metabolism Associate Executive Director for Clinical Science Baton Rouge LA Medical Research: What is the background of this study? Dr. Ravussin: It has long been postulated that hypoxia is bad for metabolic health. Hypoxia of adipose tissue has been thought to cause oxidative stress, resulting in the recruitment of macrophages with resultant secretion of cytokines and inflammation.  However, repeated bouts of hypoxia induced during vigorous exercise results in increased glucose uptake and vascularization of muscle tissue. In addition, living at high altitude is associated with a lower prevalence of impaired fasting glucose and type 2 diabetes compared with living at low altitude. Therefore, we asked the question, “What is the balance between the beneficial effects of hypoxia in muscle tissue and ‘bad’ effects in adipose tissue”? We devised a study in eight healthy men of different ethnicities, put into a hypoxic environment for 10 consecutive nights for 10 hours. The subjects slept in a hypoxic tent, using nitrogen dilution. Medical Research: What are the main findings of the study? Dr. Ravussin: The main findings of this study included:
  • Adipose tissue hypoxia was confirmed;
  • Subjects lost an average of 1.2 kg;
  • This study reports for the first time a reduced fasting glucose level and improved whole-body (skeletal muscle) and hepatic insulin sensitivity after nightly exposure to moderate hypoxia.

MedicalResearch.com interview with: Lee M. Hampton, MD, MSc: Division of Healthcare Quality Promotion Centers for Disease Control and Prevention Atlanta, Georgia Medical Research: What are the main findings of the study? Dr. Hampton: The study, which used CDC's national outpatient adverse drug event surveillance system (NEISS-CADES), found that there are almost 90,000 estimated annual emergency department visits by adults for adverse drug events from therapeutic use of antipsychotics, antidepressants, sedatives and anxiolytics, lithium salts or stimulants between 2009 and 2011. Almost one in five of those emergency department visits (19.3%) resulted in hospitalization. Sedatives and anxiolytics, antidepressants, and antipsychotics each caused 20,000 to 30,000 emergency department visits annually. However, relative to how often each of these types of medications was prescribed at outpatient visits, antipsychotics and lithium salts were more likely to cause emergency department visits for adverse drug events than were sedatives, stimulants, and antidepressants. Antipsychotics caused 3.3 times more emergency department visits for adverse drug events than sedatives, 4.0 times more emergency department visits than stimulants, and 4.9 times more emergency department visits than antidepressants relative to their outpatient use. Out of the 83 specific drugs the study looked at, ten drugs were implicated in nearly 60% of the emergency department visits for ADEs from therapeutic use of antipsychotics, antidepressants, sedatives and anxiolytics, lithium salts or stimulants. Zolpidem was implicated in nearly 12% of all such emergency department visits and 21% of such emergency department visits involving adults aged 65 years or older, more than any other antipsychotic, antidepressant, sedative or anxiolytic, lithium salt or stimulant.

MedicalResearch.com Interview with: Victoria A. Kumar, M.D. Internal Medicine/Nephrology Division of Nephrology Department of Internal Medicine Southern California Permanente Medical Group Los Angeles, California, USA Medical Research: What are the main findings of the study? Dr. Kumar: There was over a 2 fold increase in patient survival in incident peritoneal dialysis patients in the first year on dialysis compared to propensity matched incident hemodialysis patients.  We excluded any patients who utilized a central dialysis catheter at any point during the first 90 days on hemodialysis in an effort to reduce the mortality bias associated with hemodialysis patients who start with a catheter.  All hemodialysis patients had pre-dialysis care by a nephrologist prior to starting dialysis. The 2+ fold increase in survival among peritoneal dialysis patients resulted in a 2-3 year cumulative survival advantage for peritoneal dialysis patients, using both intent to treat and as-treated analyses.

Jeff Trost, MD Assistant Professor of Medicine Johns Hopkins MedicineMedicalResearch.com Interview with: Jeff Trost, MD Assistant Professor of Medicine Johns Hopkins Medicine Medical Research: What are the main findings of the study? Dr. Trost: In our study, we reported the use of two relatively simple tactics to significantly reduce the number of unnecessary blood tests to assess symptoms of heart attack and chest pain and to achieve a large decrease in patient charges. Specifically, we
  • 1) Provided information and education to physicians about proven testing guidelines and
  • 2) Made changes to the computerized provider order entry system at the medical center, part of the Johns Hopkins Health System. The guidelines call for more limited use of blood tests for so-called cardiac biomarkers. A year after implementation, our intervention led to an estimated $1.25 million reduction in laboratory charges.

Ms Qi Wu: Mental Health and Addiction Research Group, Department of Health Sciences University of York, Heslington York UKMedicalResearch.com Interview with: Ms Qi Wu: Mental Health and Addiction Research Group, Department of Health Sciences University of York, Heslington York  UK Medical Research: What are the main findings of the study? Ms Qi Wu: At any time in the UK about one in six adults has a mental health problem, the prevalence of smoking in this group is over 33%, which is around 50% higher than in the general population. It is estimated that 3 million adults with mental disorders were smokers in 2009-10. Meanwhile, people with mental health disorders are also more likely to smoke heavily, this group accounts for as much as 42% of the total national tobacco consumption.  In this study, we calculated the avoidable economic burden of smoking in people with mental disorders. The main finding was that people with mental disorders who smoke cost the UK economy £2.34 billion a year. The total costs are more or less equally divided among losses sustained from premature death, lost productivity, and healthcare costs to treat smoking related diseases such as lung cancer, cardiovascular disease and chronic obstructive pulmonary disease (COPD) in this group.  An estimated £719 million (31% of the total cost) was spent on treating diseases caused by smoking. Productivity losses due to smoking-related diseases were about £823 million (35%) for work- related absenteeism and £797 million (34%) was associated with premature mortality.

Dr. Wang-Gillam: This is a global randomized phase III trial of MM398 plus 5FU/LV vs. MM398 vs. 5FU/LV in patients with metastatic pancreatic cancer who had received prior gemcitabine-based therapy. The primary endpoint was overall survival (OS). The secondary endpoints included progression-free survival (PFS), response rate (RR), biochemical response and safety. The trial achieved its primary endpoint. The median overall survival was statistically longer with the combination of MM398 plus 5FU/LV compared with 5FU/LV alone (6.1 months vs 4.2 months; HR of 0.67; p=0.0122). A superior progression-free survival was also seen in the MM398 plus 5FU/LV group compared with the 5FU/LV alone group (3.1 months vs 1.5 months; HR of 0.56; p=0.0001). A higher response rate was observed in the combination regimen compared with the 5FU/LV group (16% vs 1%). There were no differences in overall survival or PFS between the MM 398 monotherapy and 5FU/LV groups.

Dr. Colin Cooke MD, MSc, MS Assistant Professor, Department of Internal Medicine University of Michigan Center for Healthcare Outcomes and Policy Ann Arbor, MIMedicalResearch.com Interview with: Dr. Colin Cooke MD, MSc, MS Assistant Professor, Department of Internal Medicine University of Michigan Center for Healthcare Outcomes and Policy Ann Arbor, MI Medical Research: What are the main findings of the study? Dr. Cooke: We determined that when patients who are hospitalized for pulmonary embolism (PE), a blood clot in the lung, approximately 1 in 5 will be admitted to an intensive care unit (ICU). However, the chances that a patient will go to an ICU is highly dependent upon which hospital they are admitted to. For example, some hospitals admitted only 3% of patients with pulmonary embolism to an ICU while others admitted almost 80%. Importantly, the differences in how hospitals use their ICU for patients with pulmonary embolism was not entirely related to the patient’s need for life support measures, the things that the ICU is designed to deliver. For example, the ICU patients in high ICU-use hospitals tended to receive fewer procedures, including mechanical ventilation, arterial catheterization, central lines, and medications to dissolve blood clots. This suggest that high utilizing hospitals are admitting patients to the ICU with weaker indications for ICU admission.

Robert A. Vigersky, MD Walter Reed National Military Medical Center Bethesda, MDMedicalResearch.com Interview with: Robert A. Vigersky, MD Walter Reed National Military Medical Center Bethesda, MD Medical Research: What type of patients do endocrinologists typically treat and why is the demand for their services anticipated to grow? Dr. Vigersky: Endocrinologists are physicians trained in managing, diagnosing, and treating disorders of the endocrine system:  thyroid, parathyroid, adrenal glands, hypophyseal and hypothalamic axes, ovaries, testes, and pancreas.  Their role involves controlling diabetes mellitus, menopause, hyperthyroidism and other conditions involving metabolism. A major factor affecting the anticipated demand for health care services is the aging population.  In 2010, there were 37.5 million people age 65 or over, constituting about 12.7 percent of the total population, and by 2025 the population age 65 or over will number 62.5 million (17.9 percent of the population).  Due to the greater prevalence of many of the diseases in older age groups, like osteoporosis, diabetes, obesity, and thyroid nodules, the growth in the population age 65 or over will exert a major influence on the demand for endocrine services. Diabetes, by itself, is a major driver of demand.  The incidence of Type 2 diabetes rises dramatically with age, and with obesity.  In an increasingly overweight population an estimated 22.3 million people in the U.S. are diagnosed with diabetes as of 2012, representing about 7 percent of the population. This estimate is higher than but consistent with those published by the CDC for 2010.  The percentage of the population with diagnosed diabetes continues to rise, with one study projecting that as many as one in three U.S. adults could have diabetes by 2050 if current trends continue.

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.

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).
