Author Interviews, BMJ, Primary Care, Pulmonary Disease / 13.02.2014

Professor Chris van Weel Emeritus Professor of Family Medicine/General Practice Radboud University Nijmegen, The Netherlands Professor of Primary Health Care Research, Australian National University, Canberra Past President of WoncaMedicalResearch.com: Interview with: Professor Chris van Weel Emeritus Professor of Family Medicine/General Practice Radboud University Nijmegen, The Netherlands Professor of Primary Health Care Research, Australian National University, Canberra Background from Professor Chris van Weel Thank you for the opportunity to respond to your questions.  My paper was a commentary to the study of Jones and colleagues, Opportunities to diagnose chronic obstructive pulmonary disease in routine care in the UK: a retrospective study of a clinical cohort looking at the implications of the study findings. MedicalResearch.com: What are the main findings of the study? Answer: Jones and colleagues reported that in the UK, there are many missed opportunities to diagnose COPD. My comments are that this is not a unique UK problem, but a universal one: under-diagnosis or late diagnosis of COPD is a universal problem in most if not all countries in the world. To understand it, it is important to analyse more in-depth the diagnostic challenge in primary care, for general practitioners(GP)/family physicians (FP). The paper of Jones highlights this diagnostic problem - symptoms of COPD are initially insidious and may fluctuate over time. And from my earlier research it is also clear that patients 'adept' their daily activities (less physical activities) and therefore may underplay or even become unaware of, their symptoms. At the same time, this is a problem for the physician, when encountering these symptoms. As I highlighted in my commentary, GPs/FPs have to pay attention to other possible diseases that might cause these symptoms: pneumonia, heart failure, lung cancer. The 'low key symptoms' and the need of applying a broad diagnostic scope together cause what Jones and his colleagues called the 'missed opportunities' to diagnose COPD. (more…)
Author Interviews, BMJ, Breast Cancer, Mammograms / 13.02.2014

Anthony Miller, MD Director, Canadian National Breast Screening Study Professor Emeritus, Dalla Lana School of Public Health University of TorontoMedicalResearch.com Interview with: Anthony Miller, MD Director, Canadian National Breast Screening Study Professor Emeritus, Dalla Lana School of Public Health University of Toronto MedicalResearch.com: What are the main findings of the study? Prof. Miller:  The study involved 89,835 women aged 40 to 59. All underwent an annual physical breast examination, while half were randomly assigned to undergo annual mammograms for five years, beginning in 1980. During the five-year screening period, 666 invasive breast cancers were diagnosed in the mammography arm and 524 in the controls.  Over the 25 year follow-up 180 women in the mammography arm and 171 women in the control arm died of breast cancer.  The overall hazard ratio for death from breast cancer diagnosed during the screening period associated with mammography was 1.05 (95% CI: 0.85 – 1.30).  The findings for women aged 40-49 and aged 50-59 were almost identical. After 15 years of follow-up an excess of 106 cancers was observed in the mammography arm, attributable to over-diagnosis, i.e. 22% of screen-detected invasive breast cancers, half of those detected by mammography alone. This represents one over-diagnosed breast cancer for every 424 women screened by mammography. By 2005, 3,250 of the 44,925 women in the mammography arm of the study were diagnosed with breast cancer, and 500 had died of it. The control group of 44,910 women had 3,133 breast cancer diagnoses and 505 breast cancer deaths. We conclude that annual mammography in women aged 40-59 does not reduce mortality from breast cancer beyond that of physical examination or usual care when adjuvant therapy for breast cancer is freely available.

Dr Sarah Slight, School of Medicine Pharmacy and Health, Wolfson Research Institute University of Durham, United Kingdom.MedicalResearch.com Interview with; Dr Sarah Slight, School of Medicine Pharmacy and Health, Wolfson Research Institute University of Durham, United Kingdom. MedicalResearch.com: What are the main findings of the study? Dr. Slight: Our study identified four main cost categories associated with the implementation of EHR systems, namely: infrastructure (e.g., hardware and software), personnel (e.g., project management and training teams), estates / facilities (e.g., furniture and fittings), and other (e.g., consumables and training materials). Many factors were felt to impact on these costs, with different hospitals choosing varying amounts and types of infrastructure, diverse training approaches for staff, and different software applications to integrate with the new system.

dr_jenny_hatchardMedicalResearch.com Interview with: Dr Jenny L Hatchard University of Bath and UK Centre for Tobacco and Alcohol Studies MedicalResearch.com: What are the main findings of the study? Dr. Hatchard: Our study found that global tobacco companies’ claims that standardised packaging ‘won’t work’ should be viewed sceptically. The aim of standardised packaging, with no logos, brand imagery, symbols, or promotional text, is to restrict the already limited opportunities that tobacco companies have to market their products, and deter people from starting smoking. It was introduced in Australia in 2012 and the UK Government is currently considering following suit. We analysed the evidence cited by four global tobacco companies in their lengthy responses (1521 pages in total) to a recent UK Government consultation on standardised packaging for cigarettes.

Author Interviews, BMJ, General Medicine, Mental Health Research, Pediatrics / 22.01.2014

MedicalResearch.com Interview with: Prof. Kathryn M Abel Professor of Psychiatry & Honorary Consultant Psychiatrist University of Manchester and Honorary Senior Lecturer at the Institute of Psychiatry, London. MedicalResearch.com: What are the main findings of the study? Answer: The main study findings were that exposure of a mother to a severe psychological stress of losing a close family member up to either 6 months before conception or at any time during pregnancy did not increase risk of subsequent psychotic illness in the offspring. Secondly, we found during childhood, if a close family member died then, especially a sibling of the child or one of their parents, these children were at slightly increased risk of developing a psychotic illness later in life. This was most likely to happen following a sudden death especially suicide and in particular following suicide a psychotic mood disorder was more likely than other kinds of psychosis such as schizophrenia (although the risk of schizophrenia was also increased following suicide). This effect was not accounted for by having  a family history of a psychotic illness or suicide. (more…)

Sophie Grigoriadis, MD, MA, PhD, FRCPC Head, Women's Mood and Anxiety Clinic: Reproductive Transitions, Fellowship Director, Sunnybrook Health Sciences Centre, Scientist, Sunnybrook Research Institute Adjunct Scientist, Women's College Research Institute, Associate Professor, Faculty of Medicine, University of TorontoMedicalResearch.com Interview with: Sophie Grigoriadis, MD, MA, PhD, FRCPC Head, Women's Mood and Anxiety Clinic:  Reproductive Transitions, Fellowship Director, Sunnybrook Health Sciences Centre, Scientist, Sunnybrook Research Institute Adjunct Scientist, Women's College Research Institute, Associate Professor, Faculty of Medicine, University of Toronto MedicalResearch.com: What are the main findings of the study? Dr. Grigoriadis: Infants of women exposed to selective serotonin reuptake inhibitors (SSRIs) during late pregnancy (but not early) are at risk for developing persistent pulmonary hypertension of the newborn (PPHN). PPHN is a condition in which blood pressure remains high in the lungs following birth and which results in breathing difficulties.  The symptoms can range from mild to severe, but the condition can be managed successfully typically after SSRI exposure. It is important to note that the baseline risk for PPHN in the general population is low (about 2 per 1,000 live births), and so the increase in risk with SSRIs still represents a low overall risk for developing PPHN following SSRI exposure in late pregnancy (increasing to approximately 5 per 1,000 live births). This increased risk means that 286 to 351 women would have to be treated with an SSRI during late pregnancy in order to result in 1 additional case of PPHN. (more…)

Dr Victoria J Burley Senior Lecturer in Nutritional Epidemiology School of Food Science and Nutrition University of Leeds Biostatistics, University of Leeds, UKMedicalResearch.com Interview with: Prof. Victoria J Burley Senior Lecturer in Nutritional Epidemiology School of Food Science and Nutrition University of Leeds Biostatistics, University of Leeds, UK MedicalResearch.com: What are the main findings of the study? Prof. Burley: Although it’s been suggested for a long time that foods rich in dietary fiber may protect individuals from having a heart attack or stroke because they lower some of the risk factors for these diseases, trying to determine how much dietary fibre might be beneficial and whether these benefits are apparent in all populations around the world has been less easy to research. Our research at the University of Leeds has pooled the results of published large-scale follow-up studies and has demonstrated a consistent lowering of risk of cardiovascular and coronary heart disease with increasing dietary fiber intake. This dose-response trend suggests that even small additional increments in intake may be beneficial in the long term. (more…)

Dr. Jacques Donzé MD PhD Research Associate Division of General Internal Medicine and Primary Care, Brigham and Women’s Hospital Harvard Medical School, Boston, MA 02115, USADivision of General Internal Medicine, Bern University Hospital, 3010 Bern, SwitzerlandMedicalResearch.com Interview with: Dr. Jacques Donzé MD PhD Research Associate Division of General Internal Medicine and Primary Care, Brigham and Women’s Hospital Harvard Medical School, Boston, MA 02115, MedicalResearch.com: What are the main findings of the study? Dr. Donzé: In a large retrospective cohort study, we identified the primary diagnoses of 30-day potentially avoidable readmissions in medical patients according to the most common comorbidities. Interestingly, almost all of the top five diagnoses of potentially avoidable readmissions for each comorbidity were possible direct or indirect complications of that comorbidity. Patients with cancer, heart failure, and chronic kidney disease had a significantly higher risk of potentially avoidable readmission than those without those comorbidities. Also, when readmitted, patients with chronic kidney disease had a 20% higher risk of having the readmission be potentially avoidable. (more…)

Dr. Meghan Azad, PhD Banting Postdoctoral Fellow Department of Pediatrics University of AlbertaMedicalResearch.com Interview with: Dr. Meghan Azad, PhD Banting Postdoctoral Fellow Department of Pediatrics University of Alberta MedicalResearch.com: What are the main findings of the study? Dr. Azad: In this study, our goal was to evaluate the clinical evidence for using probiotics (live "healthy bacteria") to prevent childhood asthma.  We reviewed the results of 20 clinical trials involving over 4000 infants, where probiotics were administered during pregnancy or the first year of life, and found no evidence to support the use of probiotics for asthma prevention.  Children receiving probiotics were just as likely to develop asthma as children receiving placebo.  Similarly, there was no effect of probiotic supplementation on the development of wheezing.

MedicalResearch.com Interview with: Alyshah Abdul Sultan, doctorate student Division of Epidemiology and Public Health, University of Nottingham, Clinical Sciences Building Phase 2, City Hospital, Nottingham NG5 1PB, UK MedicalResearch.com: What are the main findings of the study? Answer: Overall, we found that hospitalisation during pregnancy was associated with an excess risk of 16.6 cases per 1,000 person-years compared with time outside hospital (17.5-fold increase in risk). There was also an excess risk of 5.8 cases per 1,000 person years in the 28 days after discharge with VTE events more likely to occur in the third trimester of pregnancy and in women aged 35 years and over.

Kumar Dharmarajan MD MBA Fellow in Cardiovascular Medicine Columbia University Medical CenterMedicalResearch.com Interview with: Kumar Dharmarajan MD MBA Fellow in Cardiovascular Medicine Columbia University Medical Center MedicalResearch.com: What were the main findings of the study Dr. Dharmarajan: In the United States, 1 in 5 older patients is readmitted to the hospital within 30 days of hospital discharge. However, there is great variation in rates of 30-day readmission across hospitals, and we do not know why some hospitals are able to achieve much lower readmission rates than others. We therefore wondered whether top performing hospitals with low 30-day readmission rates are systematically better at preventing readmissions from particular conditions or time periods after discharge. For example, are hospitals with low 30-day readmission rates after hospitalization for heart failure especially good at preventing readmissions due to recurrent heart failure or possible complications of treatment? Similarly, are top performing hospitals especially good at preventing readmissions that occur very soon after discharge, which may signify poor transitional care as the patient moves form the hospital back home?

Dr. Jones: We identified a group of 585 clinical trials with at least 500 participants which had been prospectively registered with ClinicalTrials.gov and completed prior to 2009. Following an extensive search of the medical literature, we were unable to identify published manuscripts for 171 (29%) of these studies. For these unpublished studies we also determined whether results were available in the ClinicalTrials.gov results database, and we found that 133 studies had no results available either in the published literature or on ClinicalTrials.gov.

MedicalResearch.com Interview with: Adam D M Briggs Academic Clinical Fellow British Heart Foundation Health Promotion Research Group, Nuffield Department of Population Health, University of Oxford, Oxford OX3 7LF, UK MedicalResearch.com: What are the main findings of the study? Answer: For the first time this study estimates the impact of a sugary drinks tax in the UK on obesity. We estimate the tax would reduce the number of adults with obesity by around 180,000 or just over 1% of all adults who are obese, and the number of adults who are either overweight or obese by 285,000. The greatest reductions are seen in young adults. We also estimate that the effects of the tax will be similar across all income groups. (more…)

Marieke de Groot, PhD Senior Researcher University of Groningen/University Medical Center Groningen VU University Amsterdam, department of Clinical Psychology The EMGO Institute for Health and Care Research (EMGO+)MedicalResearch.com Interview with: Marieke de Groot, PhD Senior Researcher University of Groningen/University Medical Center Groningen VU University Amsterdam, department of Clinical Psychology The EMGO Institute for Health and Care Research (EMGO+) MedicalResearch.com: What are the main findings of the study? Answer: We investigated the long term course of bereavement through suicide in a community-based sample of 153 first-degree relatives and spouses of 74 suicide cases. Outcome measures were complicated grief, depression and suicide ideation. We found that outcomes are mutually strongly associated over the 8-10 years course. A history of attempted suicide predicts a increased risk of suicide ideation during the bereavement course. Depression is more likely predicted by factors generally associated with a increased risk of depression such as female gender and low mastery, whereas complicated grief is more likely predicted by the trauma of losing a child due to suicide. No significant associations were found between outcomes and the use of help resources except for mutual (or peer) support, which is associated with a increased risk of complicated grief. Time is the only factor (included in this study) predicting decrease of the risk of depression and complicated grief. (more…)

MedicalResearch.com Interview with A/Prof Susanna M Proudman MB BS (Hons) FRACP Discipline of Medicine, University of Adelaide Senior Consultant in Rheumatology Royal Adelaide Hospital North Terrace, Adelaide, 5000 MedicalResearch.com: What are the main findings of the study? Answer: In patients with early DMARD-naïve rheumatoid arthritis (RA), fish oil (delivering an average daily dose of 3.7 g dose of omega-3 fats) was associated with benefits additional to those achieved by combination treat-to-target DMARDs with similar methotrexate use. These included significantly reduced risk of triple DMARD failure, defined as needing the addition of leflunomide, and a higher rate of ACR remission. Because a structured treatment algorithm that was responsive to disease activity and tolerance was used, drug use could be used as an outcome measure for the effects of fish oil. This is one of the novel features of this study as the study design allows for a RCT to be performed on a background of treat-to-target therapy for early RA. (more…)

Response: We have three major findings.
  • First, we found that total fruit consumption was consistently associated with lower risk of developing type 2 diabetes in these large scale studies among U.S. men and women.
  • Second, we found that different individual fruits were differentially associated with diabetes risk. For example, higher intakes of blueberries, grapes or raisins, apples or pears are particularly associated with a lower diabetes risk.
  • Last, we found that fruit juice was associated with a higher diabetes risk, and replacing fruit juices with whole fruits will likely lead to reduced diabetes risk. (more…)

Overall, Mtx + etanercept was not statistically equivalent to etanercept alone (ie non-inferiority did not occur); implying 6 months after stopping Mtx, the etanercept patients on monotherapy performed slightly less well than those on combination therapy.

MedicalResearch.com Interview with: David A Richards, PhD Professor of Mental Health Services Research and NIHR Senior Investigator University of Exeter Medical School Sir Henry Wellcome Building University of Exeter Washington Singer Building The Queen’s Drive Exeter EX4 4QQ United Kingdom MedicalResearch.com: What are the main findings of the study? Answer: We found that collaborative care improves depression immediately after treatment compared to usual care, has effects that persist to 12 month follow-up and is preferred bypatients over usual care. This difference in effect equated to a standardized effect size of 0.26 (95% CI 0.07 to 0.46). More participants receiving collaborative care than those receiving usual care met criteria for recovery (odds ratio 1.67 (95% confidence interval 1.22 to 2.29); number needed to treat=8.4) and response (1.77 (1.22 to 2.58); 7.8 at 4 months. At 12 months follow up more participants in collaborative care than those in usual care met criteria for recovery (odds ratio 1.88 (95% confidence interval 1.28 to 2.75); number needed to treat=6.5) and response (1.73 (1.22 to 2.44); 7.3. Collaborative care is as effective in the UK healthcare system—an example of an integrated health system with a well developed primary care sector—as in the US. (more…)

Anemia, Author Interviews, BMJ, OBGYNE, Pediatrics / 04.07.2013

MedicalResearch.com Interview with Batool Haider, MD, MS, DSc candidate Departments of Epidemiology and Nutrition School of Public Health Harvard University Anaemia, prenatal iron use, and risk of adverse pregnancy outcomes: systematic review and meta-analysis MedicalResearch.com: What are the main findings of the study? Dr. Haider: The main findings of the study are that iron use in the prenatal period increased maternal mean haemoglobin concentration by 4.59 (95% confidence interval 3.72 to 5.46) g/L compared with controls and significantly reduced the risk of anaemia (relative risk 0.50, 0.42 to 0.59), iron deficiency (0.59, 0.46 to 0.79), iron deficiency anaemia (0.40, 0.26 to 0.60), and low birth weight (0.81, 0.71 to 0.93). The effect of iron on preterm birth was not significant (relative risk 0.84, 0.68 to 1.03). Analysis of cohort studies showed a significantly higher risk of low birth weight (adjusted odds ratio 1.29, 1.09 to 1.53) and preterm birth (1.21, 1.13 to 1.30) with anaemia in the first or second trimester. Exposure-response analysis indicated that for every 10 mg increase in iron dose/day, up to 66 mg/day, the relative risk of maternal anaemia was 0.88 (0.84 to 0.92) (P for linear trend<0.001). Birth weight increased by 15.1 (6.0 to 24.2) g (P for linear trend=0.005) and risk of low birth weight decreased by 3% (relative risk 0.97, 0.95 to 0.98) for every 10 mg increase in dose/day (P for linear trend<0.001). Duration of use was not significantly associated with the outcomes after adjustment for dose. Furthermore, for each 1 g/L increase in mean haemoglobin, birth weight increased by 14.0 (6.8 to 21.8) g (P for linear trend=0.002); however, mean haemoglobin was not associated with the risk of low birth weight and preterm birth. No evidence of a significant effect on duration of gestation, small for gestational age births, and birth length was noted. (more…)
