Scott C. Woller, MD Co-Director Thrombosis Program Intermountain Medical Center Associate Professor of Internal Medicine University of Utah School of Medicine Murray, UT 84157-7000MedicalResearch.com Interview with Scott C. Woller, MD Co-Director Thrombosis Program Intermountain Medical Center Associate Professor of Internal Medicine University of Utah School of Medicine Murray, UT 84157-7000 Dr. Woller: By way of background, D-dimer, a simple blood test that is used to investigate the diagnosis of suspected pulmonary embolism (PE), and it increases with age.  Recent research suggests that the use of an age-adjusted d-dimer threshold may improve diagnostic efficiency without compromising safety. We wished to assess the safety of using an age-adjusted d-dimer threshold in the work-up of patients with suspected pulmonary embolism. MedicalResearch:  What are the main findings of the study? Dr. Woller: In this retrospective cohort study we identified 923 patients age > 50 years who presented to our emergency department with suspected pulmonary embolism, and had their pretest probability of PE calculated along with a d-dimer performed. All patients underwent computed tomography pulmonary angiography (CTPA). We observed that among patients unlikely to have PE, adoption of an age-adjusted D-dimer cut-off (compared with a conventional D-dimer cut-off) reduced the need for CTPA in an additional 18.3% of patients, and was associated with a low 90-day rate of failure to diagnose PE.

MedicalResearch.com Interview with: Dr Renee Martin Anthera Pharmaceuticals, Inc. 25801 Industrial Blvd, Suite B., Hayward, CA 94545, MedicalResearch: What are the main findings of the study? Dr. Martin: The PEARL-SC study identified many key elements that inform the further development of blisibimod for treatment of SLE: i.         That patients with severely active disease responded well to blisibimod, ii.         That a dose of 200mg blisibimod administered subcutaneously once per week improved measures of SLE disease activity, iii.         That greater treatment effect was observed when the SRI-7 and SRI-8 endpoints were evaluated, presumably because the criteria for these endpoints (including 7- or 8- point improvements in SELENA-SLEDAI score, respectively, along with no new BILAG A or 2B scores, and no worsening of physician’s global assessment score) demand substantial improvement in disease activity compared with baseline, and are unlikely to be met by chance (e.g. in the placebo group), and iv.         That blisibimod was safe and well-tolerated over 24-52 weeks of continuous therapy.

Flor M. Munoz, MD Department of Pediatrics Department of Molecular Virology and Microbiology Baylor College of Medicine, Houston, Texas MedicalResearch.com Interview with: Flor M. Munoz, MD Department of Pediatrics Department of Molecular Virology and Microbiology Baylor College of Medicine, Houston, Texas MedicalResearch.com: What are the main findings of the study? Dr. Munoz: 1. Tdap vaccine was safe and well tolerated during pregnancy 2. Women who are pregnant have adequate responses to the Tdap vaccine, similar to those of women who are not pregnant. 3. Antibodies to pertussis are efficiently transferred to the fetus through the placenta so that babies of mothers who were vaccinated during pregnancy had significantly higher concentrations of antibody at birth and up to 2 months of age, when compared to infants of mothers who were vaccinated post-partum. 4. Higher antibody concentrations in the first two months of life are likely to provide protection against pertussis during this period of high vulnerability 5. Infants of mothers who were vaccinated during pregnancy had adequate responses to their routine pertussis vaccines at 2, 4, and 6 months of age, and had expected and adequate responses to their 4th dose of vaccine at 1 year of age. The absolute concentration of antibodies to some of the pertussis antigens might be modestly lower after the primary series of vaccines in some infants of mothers who were vaccinated during pregnancy, but this difference does not persist after the 4th dose.

MedicalResearch.com Interview with: David Lassman Statistician in the National Health Statistics Group, Office of the Actuary Centers for Medicare and Medicaid Services (CMS) Baltimore, Maryland. MedicalResearch: What types of health care spending are included in this report?  Answer: In the past, the CMS Office of the Actuary provided periodic updates of health care spending by age and more recently by gender. This report, for the first time, provides a time series of spending by age (five categories – 0-18, 19-44, 45-64, 65-84, and 85+) and gender. We also show spending by three major age categories – children (0-18), working age adults (19-64), and the elderly (age 65 and over). We present data for personal health care only which consists of all the medical goods and services used to treat or prevent a specific disease or condition in a specific person. We provide estimates for the even years between 2002 and 2010. These age and gender estimates are controlled to the most recent Historical National Health Expenditure Accounts. (more…)

MedicalResearch Interview with: Dr. Teshamae Monteith MD Assistant professor of Neurology Chief of the Headache Division University of Miami Miller School of Medicine. MedicalResearch: What are the main findings of the study? Dr. Monteith:   
  • A doubling of silent brain infarctions in those with migraine even after adjusting for other stroke risk factors;
  • No increase in the volume of white-matter hyperintensities (small blood vessel abnormalities) that have been associated with migraine in other studies;
  • Migraines with aura — changes in vision or other senses preceding the headache — wasn’t common in participants and wasn’t necessary for the association with silent cerebral infarctions.
  • High blood pressure, another important stroke risk factor, was more common in those with migraine. But the association between migraine and silent brain infarction was also found in participants with normal blood pressure.

MedicalResearch Interview with: Arya Mani, M.D. Department of Internal Medicine and Genetics Yale Cardiovascular Research Center Yale, New Haven CT Arya Mani, M.D. Department of Internal Medicine and Genetics Yale Cardiovascular Research Center Yale, New Haven CT MedicalResearch: What are the main findings of the study? Dr. Mani: Our group has identified a gene that when mutated it causes a form of truncal (central) obesity that is associated with a cluster of coronary artery disease risk factors, including high blood pressure, insulin resistance and possibly elevated blood lipids. These associated risk factors are collectively known as the metabolic syndrome, which may lead to development of diseases such as diabetes and coronary artery disease, both of which were very prevalent in the populations we studied. All identified mutations by our group have been so far gain of function mutations, which means they increased the activity of the gene in pathways related to adipogenesis and gluconeogenesis. (more…)

Patrick S. F. Bellgowan, PhD Laureate Institute for Brain Research Faculty of Community Medicine, The University of Tulsa, Tulsa, OklahomaMedicalResearch Interview with: Patrick S. F. Bellgowan, PhD Laureate Institute for Brain Research Faculty of Community Medicine, The University of Tulsa, Tulsa, Oklahoma MedicalResearch: What are the main findings of the study? Dr. Bellgowan: These results demonstrate 14% and 24% smaller hippocampal volumes in collegiate football players with and without a history of concussion relative to education-, sex- and age-matched controls participants.  Further, the number of years of tackle football experience was correlated with smaller hippocampi and slower baseline reaction times.  The hippocampus plays a key role in memory and emotional regulation.  Volumetrics of other medial temporal lobe structures (I.e. The amygdala) did NOT show differences among groups suggesting that this effect is localized to the hippocampus. (more…)

MedicalResearch.com Interview with: András Szentkirályi, MD, PhD Research fellow:Westfälische Wilhelms-Universität Münster Institut für Epidemiologie und Sozialmedizin Germany, D-4814 MedicalResearch: What are the main findings of the study? Dr. Szentkirályi : Based on two prospective, population-based cohort studies, we found that subjects having multiple chronic diseases are at an increased risk of suffering from restless legs syndrome (RLS). Moreover, increased multimorbidity was a significant predictor of developing new onset RLS. It is important to note that the observed relationship was not reduced when well-established causes of secondary restless legs syndrome (e.g. chronic renal disease) were excluded. (more…)

Robinson, MD, MPH Professor ,Departments of Epidemiology & Medicine Director, Prevention Intervention Center Department of Epidemiology College of Public Health University of Iowa Iowa City, IA 52242-2007 MedicalResearch: What are the main findings of the study? Dr. Robinson: The PCSK9 antibody, evolocumab, reduced LDL (or bad) cholesterol by about 65-70% regardless of the dose or type of statin used. This is a greater percentage reduction than ezetimibe, another drug used to lower LDL cholesterol in statin-treated patients, which lowered LDL cholesterol 15-20%. Side effects of evolocumab were similar to those for ezetimibe or placebo. (more…)

MedicalResearch Interview with: Monique Francois Teaching Fellow & Research Assistant at the University of Otago School of Physical Education, Sport and Exercise Sciences University of Otago Dunedin, New Zealand MedicalResearch: What are the main findings of the study? Answer: We found that small 'snacks' of interval exercise before the three main meals lowered postprandial blood glucose and contributed to a lower blood glucose across the day. Whereas 30 minutes of continuous moderate exercise before dinner did not lower postprandial blood glucose nor mean glucose levels the exercise day or the following day, compared to exercise snacking. Six one minute intervals as walking or a combination of walking and resistance 3x per day (before the three main meals) improved glycaemic control in individuals with insulin resistance. (more…)

MedicalResearch Interview with: Dr. Yan Qu Qingdao Municipal hospital Fruits and Vegetables Consumption and Risk of Stroke A Meta-Analysis of Prospective Cohort Studies MedicalResearch: What are the main findings of the study? Reply: First, both fruits and vegetables were found inversely associated with risk of stroke, and the relationships might be linear. Second, the inverse association of fruits and vegetables consumption with risk of stroke is consistent across subgroup analysis by outcome (stroke incidence and stroke mortality), location where the study was conducted (USA, Europe and Asia), sex (male and female), and stroke subtypes (ischemic and hemorrhagic). Third, citrus fruits, leafy vegetables and apples/pears were found inversely associated with risk of stroke. Fourth, very similar results were found in the subgroup analysis by status [yes: 0.78 (0.71-0.86) or no: 0.79 (0.74-0.85)] of adjusting for 6 or more of the 7 covariates (smoking, alcohol, blood pressure/hypertension, serum cholesterol, physical activity, body mass index, ≥3 dietary variables). These findings generally indicated that the association of fruits and vegetables consumption with the reduced risk of stroke may not be the result of confounding by the known factors. (more…)

MedicalResearch.com Interview with: Viveca Ritsinger MD Karolinska Institute, Department of Medicine, Cardiology Unit, Karolinska University Hospital, Stockholm Unit for Research and Development Kronoberg County Council, Växjö, Sweden MedicalResearch: What are the main findings of the study? Dr. Ritsinger: This is a long-term follow-up of the Swedish DIGAMI 1 study where patients with acute myocardial infarction and diabetes were randomized to either intensified insulin-based glycaemic control or to standard glucose lowering treatment. Patients and controls were followed for mortality for over 20 years and 90% of the patients died during follow up. Survival improved during a period of about 8 years. Intensified insulin-based glycaemic control increased survival time by an average of 2.3 years. (more…)

MedicalResearch.com Interview with Dr. Michael Johansen, MD, MS Department of Family Medicine The Ohio State University Columbus, OH 43201 MedicalResearch: What are the main findings of the study? Dr. Johansen: We found a surprisingly low number of people with coronary artery disease and diabetes (over age 40) were not reporting statin use. Of the people with coronary artery disease only 58% reported statin use while 52% of people with diabetes reported use. In addition, a reported diagnosis of hyperlipidemia was strongly correlated with statin use. In fact, individuals with hyperlipidemia and no coronary artery disease were more apt to be on a statin than people with coronary artery disease and no hyperlipidemia. Other high-risk conditions that have recently been included in the ACC/AHA high risk category were weakly or not associated with statin use including stroke and peripheral arterial disease. (more…)

prof_jayashri_kulharniMedicalResearch.com Interview with: Professor Jayashri Kulkarni MBBS, MPM, FRANZCP, PhD Monash University MedicalResearch.com: What are the main findings of the study? Professor Kulkarni: Persistent schizophrenia is difficult and unfortunately common, despite advances over the past years in antipsychotic drug development. New treatment approaches are urgently needed. Also, a specific focus for women with schizophrenia is still somewhat lacking and there is a need to consider the special issues facing women with schizophrenia. Over many years, we have been conducting clinical trials to develop the role of adjunctive estradiol use to treat symptoms of schizophrenia. This study is the largest clinical trial in the world of this type and we found that in an 8 week, three arm, double blind, placebo-controlled, adjunctive trial of transdermal estradiol (200mcg v 100mcg v placebo) in 183 women with schizophrenia, that the women who received either 200mcg or 100mcg transdermal estradiol made a better recovery. The women who received 200mcg transdermal estradiol made a slightly better recovery than women receiving 100mcg transdermal estradiol. Both estradiol groups were significantly better than the group who received adjunctive transdermal placebo. (more…)

Aaron L. Leppin, MD Knowledge and Evaluation Research Unit Mayo Clinic, Rochester, MinnesotaMedicalResearch.com Interview with: Aaron L. Leppin, MD Knowledge and Evaluation Research Unit Mayo Clinic, Rochester, Minnesota MedicalResearch.com: What are the main findings of the study? Dr. Leppin: We conducted a systematic review and meta-analysis of randomized trials assessing the effectiveness of hospital discharge interventions on reducing 30-day readmission rates. We identified 47 trials, 42 of which contributed to the primary meta-analysis. Overall, the interventions that have been tested to reduce early hospital readmissions reduce them by about 20%. The ones that are most effective, though, reduce them by almost 40% and use a consistent but complex approach. These interventions make a robust effort to fully understand the patient’s post-discharge context, often by visiting the patient’s home. They focus on identifying all the things the patient needs to do to be well—whether that’s organizing medications, getting a ride to the clinic, or paying the electric bill—and they determine whether the patient has the necessary resources and capacity to pull it all off. When limitations are found, these interventions have a strategy in place to support the patient through the post-discharge period. (more…)

Professor, Full SGS Member Director, Clinical Epidemiology Unit Sunnybrook Health Sciences Centre G106-2075 Bayview Avenue Toronto, ON Dr. Donald Redelmeier, MD Professor, Full SGS Member Director, Clinical Epidemiology Unit Sunnybrook Health Sciences Centre Toronto, ON MedicalResearch: What are the main findings of the study? Dr. Redelmeier: We identified every woman in Ontario, Canada, who gave birth to a newborn baby between 2006 and 2011 and then evaluated each driver for the months before, during, and after pregnancy.  This amounted to about half a million women who accounted for almost 8000 serious crashes that sent the driver to hospital.  We found that the second trimester of pregnancy led to a 42% increase in the risk of a serious motor vehicle crash.  The increased risk included diverse populations, distinct obstetrical cases, different crash characteristics. The risk equated to about twice the population norm but was still below male drivers at this age. (more…)

Dr Alexandra Pitman MBBS MRC Psych MRC Clinical Research Fellow, UCL Division of Psychiatry, UCL (University College LondonMedicalResearch.com interview with: Dr Alexandra Pitman MBBS MRC Psych MRC Clinical Research Fellow, UCL Division of Psychiatry, UCL (University College London MedicalResearch: What are the main findings of the study? Answer: We conducted a systematic review of all published research comparing the experience of suicide bereavement with bereavement due to other causes, in which we considered the evidence from 57 studies evaluating the effect of bereavement on death, mental health, and social functioning of family members, friends, and other close contacts of the deceased. These studies showed that parents and children bereaved by suicide were at higher risk of mental health problems after the loss than parents and children bereaved by other causes, and that spouses and mothers bereaved by suicide were at higher risk of suicide than spouses and mothers bereaved by other causes. We also found some evidence that people from a range of kinship groups bereaved by suicide report more rejection and shame than people bereaved by other violent deaths, and that feeling stigmatised by the death is commonly experienced after any violent bereavement. It seemed that people bereaved by violent deaths, for example due to accidental death, homicide, drug-related death, motor vehicle crash, undetermined death or suicide, shared a sense of feeling blamed for the death or tainted by their association with the deceased.

Author Interviews, Brigham & Women's - Harvard, Calcium, Heart Disease / 13.05.2014

Dr. Julie Paik, MD MPH Instructor, Harvard Medical School Brigham and Women's Massachusetts GeneralMedicalResearch.com Interview with: Dr. Julie Paik, MD MPH MSc Instructor, Harvard Medical School Brigham and Women's Hospital MedicalResearch: What are the main findings of the study? Dr. Paik: Many women in the United States take calcium supplements. One study found that over 60% of women aged 60 and over in the United States were taking calcium supplements. However, the medical community is still not certain of the effects of calcium supplements in women, particularly on cardiovascular disease risk. For this reason, we studied 74,245 women participating in the Nurses' Health Study over a 24-year follow-up period for their risk of developing cardiovascular disease (heart disease or stroke). We found that there was no increased risk of heart disease or stroke among women taking calcium supplements during the 24-year follow-up period. Our paper has several distinct strengths compared to prior studies including the large sample size, long follow-up period, cases of cardiovascular disease that were confirmed by medical record review, detailed and repeated assessment of calcium supplement use, and detailed information about other risk factors for cardiovascular disease.

MedicalResearch Interview with: Alicia J. Kowaltowski, MD, PhD Professor of Biochemistry Departamento de Bioquímica, IQ, Universidade de São Paulo São Paulo, SP, Brazil MedicalResearch: What are the main findings of the study? Dr. Kowaltowski: Intermittent fasting (24 hour cycles of all-you-can-eat followed by 24 fasting) is often used as a way to control excessive weight gain in laboratory animals, despite the fact that these animals overeat on the days they get food, and end up ingesting total quantities of food very similar to animals that eat every day. We show here that although lower weight gain occurs with intermittent fasting and there are some health benefits in adopting this diet, there are also some undesirable consequences. One such consequence is that this diet changes the control of hunger in the hypothalamus within the brain, making the rats hungry all the time, even when they are eating. (more…)
