Yigal Abramowitz, MD Cedars-Sinai Heart InstituteMedicalResearch.com Interview with: Yigal Abramowitz, MD Cedars-Sinai Heart Institute Medical Research: What is the background for this study? Dr. Abramowitz: The number of elderly patients with severe symptomatic aortic stenosis (AS) that require aortic valve replacement has been significantly increasing in recent years. However, a decade ago, third of the patients were not referred to surgery, in particular because of advanced age, and /or multiple comorbidities. TAVR has emerged as a treatment option for elderly inoperable or high-risk surgical patients with severe aortic stenosis. There is scarce evidence on the feasibility and safety of TAVR in very old patients. Medical Research: What are the main findings? Dr. Abramowitz: We compared 136 patients that were at least 90 years old at the time of TAVR (mean age: 92.4years) to 598 younger patients (mean age: 79.7years). Device success was excellent in both groups (96% for both). All-cause mortality at 30-days and 1-year was 2.9% and 12.5% vs. 2.8% and 12.3%  in patients aged ≥ 90 and ˂ 90, respectively. All major complication rates were similar between groups. (more…)

MedicalResearch.com Interview with: Nisha C. Hazra MSc Department of Primary Care and Public Health Sciences, King's College London, London, UK Medical Research: What is the background for this study? What are the main findings? Response: Our study was motivated by limited evidence about the health status of very old people, the fastest growing group of the UK population with significant implications for future NHS health-care costs. Our findings indicated an increasing number of people reaching the age of 100 years, with the increase being higher among women comparing to men (a ratio of 4 to 1). Another interesting finding was that men reaching 100 years tended to be healthier than their female counterparts. In particular, women were more likely to present multiple chronic diseases compared to men and tended to be more frail, experiencing more falls, fractures, incontinence and hearing/visual impairments.

Tess Harris St George’s University of LondonMedicalResearch.com Interview with: Tess Harris St George’s University of London   MedicalResearch: What is the background for this study? Response: Physical activity is vital for both physical and mental health in older people, preventing at least 20 common health problems. Yet the majority of older people do not achieve the World Health Organisation physical activity guidelines for health of at least 150 minutes every week of at least moderate-to-vigorous intensity physical activity in bouts that each last at least 10 minutes. Brisk walking is a good way to achieve moderate intensity physical activity, with a low risk of harm. Pedometers can give you direct feedback on your step-count and accelerometers record both step-counts and the intensity of physical activity achieved. The PACE-Lift trial assessed whether an intervention to increase walking, comprising pedometer and accelerometer feedback, combined with physical activity consultations provided by practice nurses over a 3 month period, based on simple behaviour change techniques, could lead to sustained increases in physical activity in 60-75 year olds.

Ingvild Saltvedt PhD Department of Neuroscience, Norwegian University of Science and Technology, Medical Faculty Trondheim, Norway MedicalResearch.com Interview with: Ingvild Saltvedt PhD Department of Neuroscience, Norwegian University of Science and Technology, Medical Faculty Trondheim, Norway Medical Research: What is the background for this study? What are the main findings? Dr. Saltvedt: Hip fracture patients are often old, frail and have many comorbidities. When treated with a traditional orthopaedic approach the outcomes are often poor, and many patients get functionally impaired with reduced ability to walk independently and impairment in daily life activities and with high costs for the society.  In many ways these patients are geriatric patients with hip-fractures. It has previously been shown that acutely sick geriatric patients benefit from treatment in geriatric wards and different kind of  orthogeriatric treatment models where orthopaedic surgeons and geriatricians collaborate have been studied and have shown beneficial results on short term outcomes. In the present study patients home-dwelling hip-fracture patients were randomised to orthogeriatric treatment or traditional orthopaedic treatment from admission to the hospital and during the entire stay except for the surgery that was performed similar in both groups. The study focused on long-term outcomes and also on use of health care services and cost-effectiveness.  Patients in the orthogeriatric group got comprehensive geriatric assessment and treatment performed by an interdisciplinary team that emphasised early mobilisation and rehabilitation and started discharge planning early. In the orthopaedic group traditional treatment according to national and international guidelines was offered. The primary endpoint was mobility at four months, that was better in the orthogeriatric group than in the orthopaedic group, the same difference was also shown at 12 months. In addition there were differences in instrumental activities of daily living and personal activities of daily living, quality of life and fear of falling, all differences were statistically and clinically significant and in favour of the orthoegeriatric group. The length of hospital stay was 1,7 days longer in the geriatric group, while there was no differences in days spent in hospital during one year of follow-up. One of four orthogeriatric patients were discharged directly home as compared to one of ten in the orthopaedic group. The orthopaedic group spent more days in nursing homes and rehabilitation institutions during one year of follow-up. The treatment was cost-effective in favour of the orthogeriatric group. (more…)

Kasia Joanna Lipska MD, MHS Assistant Professor of Medicine (Endocrinology) Yale School of Medicine New Haven, CT 06520-8020MedicalResearch.com Interview with: Kasia Joanna Lipska MD, MHS Assistant Professor of Medicine (Endocrinology) Yale School of Medicine New Haven, CT 06520-8020 Medical Research: What is the background for this study? What are the main findings? Dr. Lipska: Diabetes is common and affects about 1 in 4 older adults (65 years or more). For younger adults with diabetes, most guidelines suggest lowering blood sugar levels to a hemoglobin A1c below 7%. However, in older patients, especially those with complex medical problems, the benefits of this strategy are unclear. What’s more, this strategy can cause harm. Aiming for a hemoglobin A1c below seven increases the risk for hypoglycemia. And older adults are especially susceptible to this risk. As a result, many guidelines suggest that treatment should be more cautious for these vulnerable elders and that aiming for “tight” blood sugar control may not be worth the risk. Medical Research: What are the main findings? Dr. Lipska: We looked at diabetes treatment of older adults using nationally representative data from 2001 to 2010. We found that 62% of older adults with diabetes had a hemoglobin A1c below 7%. But what’s really striking is that this proportion was similar for patients who were relatively healthy, for those with intermediate health, and for those with poor health. What’s more, the use of insulin or sulfonylureas (drugs that increase the risk for hypoglycemia) was common and similar across these groups. (more…)

Helen C. Kales MD Professor of Psychiatry Director, Section of Geriatric Psychiatry and The Program for Positive Aging, University of Michigan Research Scientist, VA Center for Clinical Management Research and Geriatric Research Education and Clinical Center VA Ann Arbor Healthcare SysteMedicalResearch.com Interview with Helen C. Kales MD Professor of Psychiatry Director, Section of Geriatric Psychiatry and The Program for Positive Aging, University of Michigan Research Scientist, VA Center for Clinical Management Research and Geriatric Research Education and Clinical Center VA Ann Arbor Healthcare System Please note that this paper is the result of the deliberations of a multi-disciplinary national expert panel, not a specific study. MedicalResearch.com: What were the main findings of the expert panel? Dr. Kales: Often more than memory loss, behavioral symptoms of dementia are among the most difficult aspects of caring for people with dementia. These symptoms are experienced almost universally, across dementia stages and causes, and are often associated with poor outcomes including early nursing home placement, hospital stays, caregiver stress and depression, and reduced caregiver employment.  Doctors often prescribe these patients psychiatric medications like antipsychotics, despite little hard evidence that they work well in this population and despite the risks they pose including hastening death.  Meanwhile, studies show promise for non-medication behavioral and environmental approaches (such as providing caregiver education/support, creating meaningful activities and simplifying/enhancing the environment), but too few health providers are trained in their use.  The method created by the national multidisciplinary group of experts (DICE which stands for Describe, Investigate, Create and Evaluate) represents a comprehensive approach to assessment and management of behavioral symptoms in dementia.  For example, a new report of “agitation” from a caregiver, should be fully understood and described (e.g. who/what/when/where/risk/safety); underlying causes should be investigated (e.g. pain, changes in medications, medical conditions, poor sleep, fear); a treatment plan should be created (e.g. responding to physical problems, working collaboratively with the caregiver and other team members to institute non-pharmacologic interventions); and evaluating whether the interventions tried were effective.
