Hanna Sanoff MD, MPH Lineberger Comprehensive Cancer Center Department of Medicine University of North Carolina, Chapel Hill, NCMedicalResearch.com Interview with: Hanna Sanoff MD, MPH Lineberger Comprehensive Cancer Center Department of Medicine University of North Carolina, Chapel Hill, NC MedicalResearch.com: What are the main findings of the study? Dr. Sanoff: We measured p16, a protein that increases with cellular aging, in blood cells of women receiving chemotherapy for breast cancer. We found that a standard course of chemotherapy led to an increase in p16 expression equivalent to what we have previous seen in people over the course of 10-15 years of chronological aging. This increase persisted in cancer survivors an average of three and half years after treatment. (more…)

Paula A. Rochon MD, MPH, FRCPC Vice President, Research, Women's College Hospital Senior Scientist, Women's College Research Institute Professor, Department of Medicine University of Toronto Toronto, Ontario CanadaMedicalResearch.com Interview with Paula A. Rochon MD, MPH, FRCPC Vice President, Research, Women's College Hospital Senior Scientist, Women's College Research Institute Professor, Department of Medicine University of Toronto, Ontario Canada MedicalResearch.com: What are the main findings of the study? Dr. Rochon: Our main findings are that there are now more than 1800 centenarians in Ontario. Among those over 100 years of age, 60 per cent are 101 years of age or older. In addition, most centenarians are women (85 per cent), and this percentage increases to 90 per cent among those who are 105 years of age and older. (more…)

Professor Andrew Steptoe, MA, DPhil, DSc, FMedSci Director, Institute of Epidemiology and Health Care University College London British Heart Foundation Professor of Psychology Department of Epidemiology and Public Health London WC1E 6BTMedicalResearch.com Interview with: Professor Andrew Steptoe, MA, DPhil, DSc, FMedSci Director, Institute of Epidemiology and Health Care University College London British Heart Foundation Professor of Psychology Department of Epidemiology and Public Health London WC1E 6BT MedicalResearch.com: What are the main findings of the study? Dr. Steptoe: We are trying to understand whether positive well-being has beneficial effects as far as health and physical function is concerned.  The main findings are that the risk of developing impairments in activities of daily living (things life being able to bath or shower without help) over the next few years among older people is lower in people who enjoy life more. In addition, enjoyment of life predicted less decrease in walking speed over our 8 year study period in this sample of older men and women. Of course, these associations could be due to many things: the people with greater enjoyment of life could be more affluent, have less physical illness or disability to start with, or have healthier lifestyles at the outset, and these factors could predict the changes in physical function over time. But what we found is that baseline health, economic circumstances, and lifestyle explain only part of the association between enjoyment of life and deterioration in function. So the research suggests that enjoyment of life contributes to healthier and more active old age. (more…)

Dr. Laurent Azoulay Project Leader, Lady Davis Institute Assistant Professor, Department of Oncology, McGill UniversityMedicalResearch.com Interview with: Dr. Laurent Azoulay Project Leader, Lady Davis Institute Assistant Professor, Department of Oncology, McGill University MedicalResearch.com: What are the main findings of the study? Dr. Azoulay: Using large population-based databases from the UK, we assembled a cohort of men newly-diagnosed with non-metastatic prostate cancer. Within this group of men, the use of statins after prostate cancer diagnosis was associated with a 24% decreased risk in cancer-related mortality. We observed duration- as well as a dose-response relationships. Furthermore, in a secondary analysis, we observed that the benefits were greater among men who used also used statins before their diagnosis, with more modest yet significant benefits among men who initiated the treatment after their diagnosis. The latter result is one of the novelties of this study, as it provides an estimate of the potential benefits of statins, if used in the adjuvant setting. (more…)

Prof. Timothy Salthouse Brown-Forman Professor of Psychology Department of Psychology University of Virginia Charlottesville, VA 22904-4400MedicalResearch.com Interview with: Prof. Timothy Salthouse Brown-Forman Professor of Psychology Department of Psychology University of Virginia Charlottesville, VA 22904-4400 MedicalResearch.com: What prompted this work? Prof. Salthouse: I think it is noteworthy that the research originated as an undergraduate project by Arielle Mandell. Ms. Mandell was supported by a University of Virginia Harrison Undergraduate Research Award while she was doing the research, and a report of the research served as her Distinguished Major Thesis. The research was prompted by the observation that according to self-reports, tip-of-the-tongue experiences occur more and more frequently with increased age, and often seem to be associated with concerns about memory decline and possibly impending dementia. We wondered
  1. 1) whether these self-reports are valid, and
  2. 2) if they are valid, do they truly indicate age-related failures of the type of memory used in the diagnosis of dementia.

MedicalResearch.com Interview with: Tasnime Akbaraly  PhD Institut National de la Santé et de la Recherche Médicale Montpellier, France MedicalResearch.com: What are the main findings of the study? Dr. Akbaraly: The aim of this study was to examine the association between chronic inflammation and a range of aging phenotypes, assessed approximately 10 years later in a large British population of men and women  -The Whitehall II Study-. As inflammation characterises a wide range of pathological processes, we considered several aging phenotypes, including cardiovascular disease (fatal and non-fatal), non-cardiovascular mortality and successful aging which encompasses optimal functioning across different physical, mental, and cognitive domains We found that chronic inflammation characterized by high levels of interleukin-6 (>2 pg/mL) twice over the 5-year exposure period nearly halved the odds of successful aging after 10–years of follow-up compared to maintaining low levels of interleukin-6 (<1pg/mL twice over the exposure period). Chronic inflammation was also associated with increased odds of future cardiovascular disease and non-cardiovascular mortality in a dose-response fashion. These associations were found to be independent of socio-economic factors, health behaviours (smoking, physical activity), and conditions such as obesity as well as the use of anti-inflammatory drugs and acute inflammation.
