Mary-Ann Fitzcharles, MB, ChB, MRCP(UK), FRCP(C) McGill University Health Centre Division of Rheumatology and Alan Edwards Pain Management UnitMedicalResearch.com Interview with: Mary-Ann Fitzcharles, MB, ChB, MRCP(UK), FRCP(C) McGill University Health Centre Division of Rheumatology and Alan Edwards Pain Management Unit MedicalResearch.com: What are the highlights of your review? Dr. Fitzcharles: Thank you for your interest in the review article which will shortly be published in Arthritis Care & Research. This was not a research study but rather a review focused towards the use of herbal cannabis for patients with rheumatic diseases. The essence of our message after a thorough review of the literature is that there is not a single study published regarding efficacy or side effects of herbal cannabis in the rheumatic diseases. It is notable that almost 2 thirds of persons using herbal cannabis for therapeutic reasons report use for musculoskeletal complaints. In the 21st century, we cannot rely upon heresay or anecdote to justify use of a treatment intervention. It is unacceptable to recommend use of a substance without knowledge of concentration of molecules in the product, any knowledge of blood concentrations that might have a positive or negative effect, and formal study in defined patient populations with acceptable endpoint criteria and evidence for short and long term risks.

Sameer Saini MD Veterans Affairs Center for Clinical Management Research, VA Ann Arbor Healthcare System Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USAMedicalResearch.com Interview with: Sameer Saini MD Veterans Affairs Center for Clinical Management Research, VA Ann Arbor Healthcare System Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA MedicalResearch.com: What are the main findings of the study? Dr. Saini: The way that quality measures are defined can have important implications for how care is actually delivered. Current colorectal cancer screening quality measures use age to identify screen-eligible patients, encouraging screening in patients between 50 and 75 years of age. But they do not explicitly incorporate health status. In this context, our study had two main findings.
  • First, by focusing on age alone, we are not screening everyone who is likely to benefit. Specifically, many healthy people over 75 years of age (who are outside the target age range of the quality measure) may benefit from screening, but the current measure does not encourage screening in this population, leading to low screening use.
  • Second, some people who are NOT likely to benefit are being screened unnecessarily, like those with serious health problems. For example, people between ages 70-75 with serious health problems (who have limited life expectancy) are unlikely to benefit from screening, and may even be harmed by it. But the current quality measure encourages screening in such individuals due to their age, yielding relatively high screening rates. If the system focused on age and health status (rather than age alone), screening use would be more aligned with screening benefit, and we would have better health outcomes.

Dr. Laurie K. Twells, PhD School of Pharmacy, Memorial University, St. John’s Faculty of Medicine, Memorial University St. John’sNewfoundland and LabradorMedicalResearch.com Interview with: Dr. Laurie K. Twells, PhD School of Pharmacy, Memorial University, St. John’s Faculty of Medicine, Memorial University St. John’s Newfoundland and Labrador MedicalResearch.com: What are the main findings of the study? Dr. Twells: Obesity rates in Canada tripled between 1985 and 2011. Although class I obesity (BMI ≥ 30) appears to have increased at a slower rate, obese classes II (BMI ≥  35) and III (BMI ≥40) continued to increase disproportionately. Over the last decade, every province in Canada experienced increases in obesity rates. Overall obesity rates were lower in the west and higher in the eastern provinces and people over age 40 years were more likely to be overweight/obese than younger people. By 2019 it is projected that twenty-one per cent of Canadians will be obese but this will vary by province from 15.7% in British Columbia to 34.6% in Newfoundland and Labrador. (more…)

Professor Linda H Aiken PhD, FAAN, FRCN, RN Claire M. Fagin Leadership Professor in Nursing, Professor of Sociology Director of the Center for Health Outcomes and Policy Research Center for Health Outcomes and Policy Research University of Pennsylvania School of NursingMedicalResearch.com Interview with: Professor Linda H Aiken PhD, FAAN, FRCN, RN Claire M. Fagin Leadership Professor in Nursing, Professor of Sociology Director of the Center for Health Outcomes and Policy Research Center for Health Outcomes and Policy Research University of Pennsylvania School of Nursing MedicalResearch.com: Austerity measures and health-system redesign to minimise hospital expenditures risk adversely affecting patient outcomes. Against that backdrop, can you start by letting us know the background of the study?  Prof. Aiken: European Surgical Outcomes Study in 28 countries showed higher than necessary deaths after surgery. A comparable study in the US showed that despite the nation spending hundreds of millions of dollars on improving patient safety, there were no improvements in adverse outcomes after surgery in US hospitals between 2000 and 2009.  Clearly it is time to consider new solutions to improving hospital care for surgical patients, who make up a large proportion of all hospital admissions.  Our study was designed to determine whether there are risks for patients of reducing hospital nurse staffing, and what, if any, are the benefits to patients of moving to a more educated nurse workforce.

Answer: We found interestingly that patients with sleep apnea experienced a 1.20-fold (95% CI, 1.10-1.31; p <0.001) increase in incident pneumonia compared to patients without sleep apnea. We also demonstrated an “exposure-response relationship,” in that the patients with more severe sleep apnea might have a higher risk for pneumonia than did those of milder severity. (more…)

Grim Department of Anesthesiology Mayo Clinic, Rochester, MN 55905 MedicalResearch.com: What are the main findings of the study? Dr. Grim: “The current guidelines say that if possible, treating the dental problems that patients have before heart surgery is best, to try to prevent both early and late heart infections. But the data is very unclear, because it’s very difficult to study. We found in our study that their risk of serious complications after having teeth removed may be higher than we thought. We were primarily looking at stroke, heart attack, renal failure and death. We found that actually the incidence of having one of those major morbidities was 8 percent.  Of that 8 percent, we had six patients, or 3 percent, of the total group who died between their dental surgery and scheduled heart surgery, so these patients never made it to their heart surgery. An additional 3 percent of patients died after heart surgery. “ (more…)

Leis, MD, MSc Sunnybrook Health Sciences Centre Toronto, ON, M4N 3M5, Canada MedicalResearch.com: What are the main findings of the study? Dr. Leis: We know that positive urine cultures from patients who lack signs and symptoms of urinary tract infection are a trigger FOR unnecessary antibiotic prescriptions in hospitals. This problem has not improved despite many educational initiatives.  We identified a subset of patients in our hospital where only 2% of all urine specimens sent to the laboratory were associated with symptomatic infection and decided to no longer routinely report positive results from these specimens on the electronic medical record, unless a special telephone request was made.  We found that with this simple change, unnecessary antibiotic prescriptions declined markedly and this did not require any education of care providers. Most importantly, based on our safety audits, patients who had a urinary tract infection all received appropriate treatment. (more…)

Dr. D'Acremont: We discovered that, in a rural and an urban area of Tanzania, half of the children with fever (temperature >38°C) had an acute respiratory infection, mainly of the upper tract (5% only had radiological pneumonia). These infections were mostly of viral origin, in particular influenza. The other children had systemic viral infections such as HHV6, parvovirus B19, EBV or CMV. Overall viral diseases represented 71% of the cases. Only a minority (22%) had a bacterial infection such as typhoid fever, urinary tract infection or sepsis due to bacteremia. Malaria was found in only 10% of the children, even in the rural setting. (more…)

Dr. Ido Weinberg MD MSc MHA Massachusetts General Hospital, Vascular MedicineMedicalResearch.com Interview with: Dr. Ido Weinberg MD MSc MHA Massachusetts General Hospital, Vascular Medicine MedicalResearch.com: What are the main findings of the study? Dr. Weinberg: The study examined the relationship between blood pressure difference between arms and clinically meaningful outcomes such as death and new-onset (incident) cardiovascular disease including myocardial infarction and stroke. The main finding of the study was that an elevated inter-arm blood pressure difference correlated with these negative outcomes. We have also shown that the correlation was strong enough to be independent from the classic Framingham risk score. Adding an elevated inter-arm blood pressure to the risk score made it a more accurate. (more…)

Dr. D'Onofrio: The main finding from our study is that the specific associations between advancing paternal age at childbearing and offspring psychiatric and academic problems were much larger than in previous studies. In fact, we found that advancing paternal age was associated with greater risk for several problems, such as Attention Deficit Hyperactivity Disorder, suicide attempts and substance use problems, whereas traditional research designs suggested advancing paternal age may have diminished the rate at which these problems occur.

Dr. Skillbäck: There were two main findings in this study. First; Levels of t-tau and the T-tau/P-tau ratio in CSF of CJD (Creutzfeldt-Jakob Disease) patients are markedly increased, as compared to patients with Alzheimer's disease and other dementias, and they  are high enough to distinguish CJD against these important differential diagnoses. Secondly, levels of these biomarkers tend to increase rapidly with disease progress in Creutzfeldt-Jakob Disease. This trend could not be observed for Alzheimer's disease and other dementias, and could also be used to clinically distinguish CJD and indicates that repeated CSF measurements might be of value if a clinical suspicion of Creutzfeldt-Jakob Diseaseis present.

Dr. Risérus: It has previously been shown in animal studies that overfeeding polyunsaturated fat causes less fat accumulation than saturated fats, but this study is the first to suggest that this could be true also in humans. Overeating saturated fats caused significantly more accumulation of fat in the liver and intra-abdominally, as compared with overeating polyunsaturated fats from. This study suggests it does matter where the excess calories come from when we gain weight. If a high-caloric diet contains large amounts of saturated fats it seems to switch on some genes that may promote abdominal fat storage and insulin resistance, and thereby result in a more unfavorable fat storage. In contrast, such effects were not seen if the diet was lower in saturated fats but higher in polyunsaturated fats from non-tropical vegetable oils. This study also suggests a novel contributing factor regarding the tendency of some individuals to accumulate fat in the liver and abdomen, i.e. in some people excessive amounts of saturated fat in combination with sugars might induce more fat in their livers and a propensity towards abdominal visceral fat accumulation.

Dr. Ogden: We continue to track obesity levels in the US population using data from the National Health and Nutrition Examination Survey. New data are now available for 2011-2012. We found that 17% of youth and 35% of adults were obese.  Overall there has been no change in obesity levels among either youth or adults in the last 10 years. The prevalence of obesity among youth was 16.9% - exactly the same as in 2009-2010.  In separate age groups analyses we found a decrease in obesity among 2-5 year olds and an increase in obesity among older women 60+ years.

Signe Sørup, PhD Research Center for Vitamins and Vaccines (CVIVA) Bandim Health Project, Statens Serum Institut Artillerivej 5, DK-2300 Copenhagen S, DenmarkMedicalResearch.com Interview with: Signe Sørup, PhD Research Center for Vitamins and Vaccines (CVIVA) Bandim Health Project, Statens Serum Institut Artillerivej 5, DK-2300 Copenhagen S, Denmark MedicalResearch.com: What are the main findings of the study? Dr. Sørup: We found that admissions with any type of infection was reduced with 14 % for Danish children having the live, attenuated vaccine against measles, mumps, and rubella (MMR) as the most recent vaccine compared with children having the inactivated vaccine against Diphtheria, Tetanus, Pertussis, Polio, and Haemophilus Influenzae type b (DTaP-IPV-Hib) as the most recent vaccine. In Denmark herd immunity against measles, mumps, and rubella is high and only 26 of the more 42,000 admissions was related to measles, mumps, and rubella; so this finding cannot be explained by the specific protection against the targeted diseases. In Denmark MMR vaccination is recommended at 15 months of age, but only 50% of the children in the study had received MMR before 16 months of age. We estimated that one hospital admission between 16 and 24 months of age could be avoided for 201 children vaccinated with MMR before 16 months of age rather than later. These results are based on a retrospective cohort study including approximately half a million Danish children. The analyses are adjusted for age and a long range of background factors, including socio-economic factors. (more…)

Dr. Ishimura: Poor glycemic control is a major factor in the overestimation of glomerular filtration rate (GFR) in diabetic patients. We found this simple conclusion by directly measuring GFR by use of inulin clearance. We have created new formulae to accurately assess the GFR in diabetic patients, with the correction of hemoglobin A1C (HbA1C) or glycated albumin (GA) as followings; 1)      eGFRcr corrected by HbA1c=eGFRcr / (0.428 + 0.085 × HbA1c) 2)      eGFRcr corrected by GA=eGFRcr / (0.525 + 0.028 × GA) (more…)

Dr. Olsen: Acetaminophen (paracetamol) is drug being used by many, including pregnant women. In our data about half of all pregnant women in 1995 to 2002 had used the drug all least once during their pregnancy. The drug has shown hormonal disruptor properties in animal studies. We found that women who used this drug during pregnancy gave birth to children who 5 – 10 years later slightly more often had behavioral problems or were treated for ADHD. The risk was highest for those who took the medication late in pregnancy and/or had taken the drug several times. The increased risk was about 10-30%. (more…)

Ny, NY Department of Epidemiology Johns Hopkins Bloomberg School of Public Health Baltimore, MD MedicalResearch.com: What are the main findings of the study? Dr. Friedman: The main finding is that programs that helped protect people who inject drugs from HIV and those that helped them to get medical care seem to be associated with less HIV disease and less death related to HIV disease among the heterosexual population of large United States metropolitan areas. This is important.  Drug users in the US are widely despised, and their has been a lot of political opposition to programs like syringe exchange and drug abuse treatment. Our findings show that these programs are associated with better health and less death in the broader population.  It makes more sense to help people--even those you despise--stay uninfected, and to get medical care, than to restrict or attack programs for them.

Dr. Krakauer: We studied the association between the recently proposed body shape index (ABSI) -- which combines waist circumference, height and weight measurements -- and risk of death in a United Kingdom population sample. We found that high ABSI predicted greater mortality hazard, with death rates increasing by about 13% per standard deviation increase in ABSI. Further, ABSI was a stronger predictor of early death than BMI, waist circumference, or other indices based on waist circumference such as waist to height ratio and waist to hip ratio. For a given starting ABSI value, reducing A Body Shape Index over a 7-year period was associated with lowered mortality risk, .

Kazi, MD, MSc, MS Assistant Adjunct Professor Division of Cardiology San Francisco General Hospital Department of Medicine, and Department of Epidemiology and Biostatistics University of California San Francisco MedicalResearch.com: What is the background of your study? Dr. Kazi: When we first asked the research question -what is the role of genotyping among patients receiving a stent for ACS, we quickly realized that there were no RCTs that had directly compared ticagrelor with prasugrel. But in our opinion, that was precisely the reason to build a model and systematically synthesize the available literature. There are nearly half a million PCIs for ACS in the US each year, and each time, the physician and patients have to examine the trade-offs between the various alternatives. What our model does is that it explicates the trade-offs - makes them transparent, and quantifies them.  So patients and physicians can make an informed decision on what is the optimal therapy for them.
