Alzheimer's - Dementia / 25.02.2014

Dr. Erin Abner Ph.D. Assistant Professor of Epidemiology University of Kentucky College of Public Health Lexington, KentuckyMedicalResearch.com Interview with: Dr. Erin Abner Ph.D. Assistant Professor of Epidemiology University of Kentucky College of Public Health Lexington, Kentucky MedicalResearch.com: What are the main findings of the study? Dr. Abner:  The findings from this study are preliminary results from The Prevention of Alzheimer’s Disease with Vitamin E and Selenium Study. This early look at the data indicates that very simple measures of memory change, in this case asking older men with no cognitive impairment about changes in their memory over the past year, and whether they believe those changes are a problem, can be used to predict cognitive impairment years later. Men who said at study baseline that the changes in their memory represented problems to them were over twice as likely as men who did not complain to develop clinically detectable cognitive impairment during follow-up. This is exciting because the field of Alzheimer’s research is moving toward earlier intervention in the disease process. As of now, our best methods for identifying individuals without cognitive impairment who are likely to develop Alzheimer’s disease in the future are procedures that many people find intimidating, like lumbar puncture and PET scanning. Identifying older adults at high risk for future cognitive impairment with low-cost, non-invasive screening techniques would help researchers to target potential therapies to the people who stand to benefit the most.

MedicalResearch.com Interview with: Cynthia L. Ogden, PhD, MRP Epidemiologist and Analysis Branch Chief NHANES Program/NCHS/CDC Hyattsville, MD 20782 MedicalResearch.com: What are the main findings of the study? 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…)

Answer: The main findings of the study were that despite being of similar age, the postmenopausal displayed higher blood pressure and higher blood levels of an early marker of atherosclerosis than women that had not reached menopause. Furthermore, just 12 weeks of floorball training twice a week for one hour improved the women’s conditions and reduced their blood pressure significantly. In addition, there was positive development in levels of substances vital to blood vessel function, including a decrease in the early marker of atherosclerosis. (more…)

MedicalResearch.com Interview with: Eiji Ishimura, MD, PhD, FASN, FACP Osaka City University Hospital Professor,Department of Nephrology Osaka, JAPAN MedicalResearch.com: What are the main findings of the study? 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…)

Jørn Olsen, M.D., Ph.D. Professor Institute of Public Health, Department of Epidemiology UCLA Aarhus University Aarhus,DenmarkMedicalResearch.com Interview with: Jørn Olsen, M.D., Ph.D.  Professor Institute of Public Health, Department of Epidemiology UCLA Aarhus University Aarhus,Denmark MedicalResearch.com: What are the main findings of the study? 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…)

Samuel R. Friedman PhD Institute of Infectious Disease Research National Development and Research Institutes, Inc. New York, NY Department of Epidemiology Johns Hopkins Bloomberg School of Public Health, Baltimore, MDMedicalResearch.com Interview with: Samuel R. Friedman PhD Institute of Infectious Disease Research National Development and Research Institutes, Inc. 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.

Nir Y. Krakauer Ph.D Assistant Professor Department of Civil Engineering The City College of New York New York, New YorkMedicalResearch.com Interview with: Nir Y. Krakauer Ph.D Assistant Professor Department of Civil Engineering The City College of New York New York, New York MedicalResearch.com: What are the main findings of the study? 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, .

Dhruv S. 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 FranciscoMedicalResearch.com Interview with: Dhruv S. 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.

Author Interviews, Blood Pressure - Hypertension, JAMA, Vegetarians / 24.02.2014

MedicalResearch.com Interview with: Yoko Yokoyama, Ph.D., M.P.H. National Cerebral and Cardiovascular Center, Osaka, Japan, MedicalResearch.com: What are the main findings of the study? Dr. Yokoyama: We found consistent evidence that a vegetarian diet has a significant blood-pressure-lowering effect, and this was clear both in observational studies of individuals who had chosen vegetarian diets on their own and in intervention trials in which people were asked to make diet changes. Our meta-analysis included 32 observational studies and 7 controlled clinical trials. In the observational studies, vegetarian diets were associated with blood pressures that were about 7 mmHg lower systolic and 5 mmHg lower diastolic. In the clinical trials, the reductions were about 5 mmHg systolic and 2 mmHg diastolic. These are pooled averages, so for some individuals, particularly those with higher body weights or higher blood pressures at the beginning, the blood-pressure-lowering effects could be much greater.

Dr. Bai: Recently, we found a dilemma phenomenon that the incidence of chronic obstructive pulmonary disease (COPD) and lung cancer has remained high in southwest China despite the 1976 National Stove Improvement Program for indoor air quality. However, little information is known to the public about a regional endemic related to Chinese waterpipe smoking, which is different from the Arabic waterpipe. The Chinese waterpipe has been traditionally misconceived as less harmful for three reasons:
  • (1) no charcoal was used in contrast to the Arabic waterpipe,
  • (2) tobacco smoke passed through the water as opposed to cigarette smoking and
  • (3) smoking through a large volume waterpipe could “improve lung function.”
In our study, we provide robust results that the large volume Chinese waterpipe use and exposure are associated with the elevated prevalence of COPD, which have been identified by epidemiologic, physiologic, radiology, and toxicologic findings for the first time. (more…)

A van Dongen, MD Univ Med Ctr Utrecht Julius Ctr Hlth Sci & Primary Care, Dept Epidemiol Utrecht, Netherlands. MedicalResearch.com: What are the main findings of the study? Answer: We performed a pragmatic trial, in which we randomly assigned 230 children who had acute tympanostomy-tube otorrhea to receive antibiotic-glucocorticoid eardrops, oral antibiotics or to undergo initial observation. The primary outcome of our study was the presence of ear discharge, 2 weeks after study-group assignment. We also looked at, among others, the duration of the initial otorrhea episode and the total number of days of otorrhea and the number of otorrhea recurrences during 6 months of follow-up. We found that antibiotic–glucocorticoid eardrops were superior to oral antibiotics and initial observation for all outcomes.

Mehta, M.B., Ch.B. F.A.S.T.R.O. Professor of Radiation Oncology, University of Maryland School of Medicine Radiation oncologist, University of Maryland Marlene and Stewart Greenebaum Cancer Center MedicalResearch.com: What are the main findings of the study? Dr. Mehta: RTOG 0825 was a clinical trial evaluating whether the addition of a novel drug that inhibits tumor vascular growth, bevacizumab, to the standard of care for glioblastoma, an aggressive brain tumor, would prolong survival. Patients were allocated randomly to one of two different treatment regimens – the standard of care, which includes radiotherapy and a drug known as temozolomide, or another regimen of radiation, temozolomide and bevacizumab. The trial design was double-blinded, and therefore, on one arm patients received the bevacizumab, whereas on the other arm they received a placebo. The survival on both arms was equivalent, and therefore it was fairly concluded that bevacizumab failed to prolong survival when given initially as part of treatment for glioblastoma. Freedom from progression, referred to as progression-free survival was also measured on this trial, and although bevacizumab appeared to lengthen progression-free survival, this level of benefit did not meet the pre-defined goals, and is therefore regarded as statistically not demonstrating an improvement. Additional endpoints included outcomes reported by the patient, including the burden of symptoms, and the impact of these on the quality of life, as well as effects on the brain, known as neurocognitive changes. Bevacizumab did not improve these endpoints either.

Dr. Salhia: Our study identified novel rare genomic and epigenomic events underlying breast cancer metastasis to brain. We demonstrated that we could molecularly subtype breast cancer brain metastasis the same way we can subtype primary breast cancer. From this analysis we found that the Luminal B subtype was the most common subtype in our cohort, followed by Her2+/ER- enriched tumors and Basal-like tumors. Each of these subtypes displayed genetic and epigenetic features reminiscent of primary breast cancer. We demonstrated that these tumors have a strong predilection to grow by activating pathways involved in G2/M cell cycle progression, whereas, many genes involved in cell migration were epigenetically silenced. Broad amplification of chromosome 8q was common, which resulted in the upregulation of important genes. (more…)

Norbert Stefan, MD Heisenberg Professorship for Clinical and Experimental Diabetology Department of Internal Medicine IV University Hospital Tübingen Tübingen, GermanyMedicalResearch.com Interview with: Norbert Stefan, MD Heisenberg Professorship for Clinical and Experimental Diabetology Department of Internal Medicine IV University Hospital Tübingen Tübingen, Germany MedicalResearch.com: What are the main findings of the study? Dr. Stefan: Currently there is little evidence for an effective and safe pharmacological treatment of nonalcoholic fatty liver disease (NAFLD). Based on the fact that inhibition of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), the enzyme, that converts inactive cortisone into active cortisol in metabolic tissues such as liver and adipose, was found to be effective to improve lipid metabolism in animals, we hypothesized that inhibition of 11β-HSD1 may also prove to be effective to decrease liver fat content in patients with NAFLD. In our 12 week trial in 82 patients with NAFLD, inhibition of 11β-HSD1 with RO5093151 resulted in a 14 % decrease of liver fat content and in a resolution of NAFLD in 20 % of the patients. This was accompanied by a decrease of liver enzymes. Furthermore, inhibition of 11β-HSD1 brought about a reduction of body weight and total body- and visceral adipose tissue mass, while insulin sensitivity did not change. In agreement with findings from other trials, also in our study 11β-HSD1 inhibition was well tolerated and safe. (more…)

Dr. Dunlop: We know being active, especially doing moderate activity like taking a brisk walk, is good for health. We know a sedentary lifestyle leads to health problems. What we do not know is whether or not those are two ways of looking at the same question. Does being sedentary like sitting just reflect insufficient activity OR is sedentary time is a separate and distinct risk factor for health problems. Our physical activity research group looked at national US data from the National Health and Nutrition Examination Survey.  This is an important study because they monitored physical activity using an accelerometer.  We found sedentary behavior such as sitting was its own separate risk factor for disability.

Dr Heike Daldrup-Link Associate Professor of Radiology Stanford University School of Medicine, Palo AltoMedicalResearch.com: Interview with: Dr Heike Daldrup-Link Associate Professor of Radiology Stanford University School of Medicine, Palo Alto   MedicalResearch.com: What are the main findings of the study? Answer: We use magnetic resonance imaging, a technology based on magnetic fields rather than radiotracers or x-rays. The underlying technology is not new – it has been used for tumor staging for many years. This is an advantage as MR scanners are available in nearly every major Children’s Hospital where children with cancer are treated. What is new about our approach is that we combined anatomical and functional images, similar to current approaches that use radiotracers and CT (PET/CT):  We first acquired scans that showed the anatomy of the patient very well and we then acquired scans that depict tumors as bright spots with little or no background information. We did that by using an iron supplement as a contrast agent: The iron supplement can be detected by the MRI magnet and improved tumor detection and vessel delineation MR scans. We then fused the anatomical scans with the tumor scans. (more…)

Dr. Jane Muncke PhD Managing Director Food Packaging Forum Foundation Zurich, SwitzerlandMedicalResearch.com Interview with: Dr. Jane Muncke PhD Managing Director Food Packaging Forum Foundation Zurich, Switzerland MedicalResearch.com: What are the main conclusions from your work? Answer: Food packaging is a relevant, but still under-recognized source of chemical contamination in foods. Everybody is exposed to these chemicals on a daily basis, but we have very little understanding of the actual health effects caused by this chronic exposure source. We propose that epidemiological research tackles chemical exposures from food packaging as a new and highly relevant exposure source. Epidemiologist have played crucial roles in advancing understanding of health issues, for example cardiovascular disease caused by fine particulate air pollution. Through their work they have encouraged toxicologists to ask different questions, thereby supporting the generation of critical knowledge and, essentially, enabling prevention. (more…)
