Author Interviews, CMAJ, Exercise - Fitness, Frailty, Geriatrics, Lifestyle & Health / 21.08.2017

MedicalResearch.com Interview with: Olga Theou, MSc PhD Assistant Professor, Department of Medicine, Dalhousie University Affiliated Scientist, Geriatric Medicine, Nova Scotia Health Authority Adjunct Senior Lecturer, School of Medicine, University of Adelaide Halifax, Nova Scotia  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We already know that moderate to vigorous intensity physical activity, such as time accumulated during exercise, is associated with numerous health benefits. More recent studies also have shown that sedentary time, such as time accumulated during prolonged sitting at work, transportation, and leisure, can also increase the risk of adverse outcomes. What was not known was whether prolonged sitting affects people across different levels of frailty similarly. This is what we examined in our study. We found that there were differences. Low frailty levels (people who are extremely healthy; frailty index score < 0.1) seemed to eliminate the increased risk of mortality associated with prolonged sitting, even among people who did not meet recommended physical activity guidelines. Among people with higher frailty levels, sedentary time was associated with mortality but only among those who did not meet recommended physical activity guidelines (more…)
Author Interviews, Exercise - Fitness, Geriatrics, JAMA / 15.08.2017

MedicalResearch.com Interview with: Jennifer Brach, Ph.D., P.T. Associate professor, Department of physical therapy School of Health and Rehabilitation Sciences University of Pittsburgh MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study compared two different group exercise programs to improve mobility in community-dwelling older adults. The first program, a seated program focused on strength, endurance and flexibility, was based on usual care. The second program, called On the Move, was conducted primarily in standing position and focused on the timing and coordination of movements important for walking. Both programs met two times per week for 12 weeks. It was found that the On the Move program was more effective at improving mobility than the usual seated program. (more…)
Author Interviews, Geriatrics, Psychological Science / 15.08.2017

MedicalResearch.com Interview with: Johanna MH Nijsten, Msc Clinical Neuropsychologist Archipel Landrijt, Knowledge Center for Specialized Care Eindhoven, the Netherlands Department of Primary and Community Care, Radboudumc Alzheimer Center Radboud University Medical Center Nijmegen, the Netherlands  MedicalResearch.com: What is the background for this study? Response: Apathy is common in nursing home (NH) patients with dementia and is repeatedly found to be the most prevalent neuropsychiatric symptom. Apathy is defined by diminished or lack of motivational, goal-directed behavior, and a lack of cognition and emotional affect. Apathy leads to reduced interest and participation in the main activities of daily living, diminished initiative, early withdrawal from initiated activities, indifference, and flattening of affect. Over the last two decades, more scientific knowledge has become available about specific fronto-subcortical systems in the brain that may be highly involved in apathy. Disruptions in these systems are found in patients with frontal lobe damage resulting from, for instance, (early-onset) dementia, traumatic brain injury, stroke, or multiple sclerosis. Fronto-subcortical circuits also play an important role in neurological disorders involving the basal ganglia such as Parkinson’s disease and Huntington’s disease. The neurodegenerative diseases and acquired brain injuries mentioned here are highly prevalent in patients receiving long-term NH care and the widespread clinical manifestation of apathy in NH-patients is thought to be related. Since apathy is very common in nursing home-patients and may lead to a poor prognosis, clear insight into its risk for mortality is needed and NH-staff need to understand this risk. (more…)
Accidents & Violence, Alzheimer's - Dementia, Author Interviews, Depression, Geriatrics, Karolinski Institute / 11.08.2017

MedicalResearch.com Interview with: Heidi Taipale, PhD Pharm Senior Researcher School of Pharmacy, University of Eastern Finland; and Department of Clinical Neuroscience Karolinska Institutet  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Antidepressant use among older persons has been associated with an increased risk of falling and fall-related events, such as hip fractures, in previous studies. Our previous study identified risk of hip fractures in antidepressant among persons with Alzheimer’s disease. As falling is the main causal factor for head traumas and traumatic brain injuries among older persons, we hypothesized that antidepressant use could also be associated with these injuries. We utilized a nationwide cohort of 70,718 persons newly diagnosed with Alzheimer’s disease, identified from the Finnish registers. The risk of head injuries and traumatic brain injuries was compared between persons initiating antidepressant use and comparison persons of the same age, gender and time since they received diagnoses of Alzheimer’s disease but not using antidepressants. We found a 40-percent increased risk of head injuries and 30-percent increased risk of traumatic brain injuries associated with antidepressant use. Antidepressant use was associated with a higher risk of head injuries especially at the beginning of use – during the first 30 days – but the risk persisted even longer, up to two years. The association was also confirmed in a study design comparing time periods within the same person, thus eliminating selective factors. (more…)
Author Interviews, Blood Pressure - Hypertension, Geriatrics, JAMA / 17.07.2017

MedicalResearch.com Interview with: Donal J. Sexton, BSc, MD The Irish Longitudinal Study on Ageing Trinity College Dublin Health Research Board Clinical Research Facility Galway National University of Ireland Galway, Galway, Ireland Trinity Health Kidney Centre, Tallaght Hospital Department of Nephrology, Beaumont Hospital, Royal College of Surgeons of Ireland Dublin, Ireland MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this study we used the inclusion criteria for SPRINT to identify those community dwelling elders who would meet criteria for the trial in clinical practice. Our data are based on a prospective cohort study composed of participants chosen by a national stratified random sampling mechanism. If SPRINT participants were truly representative of the population, then the participants in the standard care arm of the trial should resemble the population to some extent. If this were true then the injurious falls rate might be similar between the two samples also. (more…)
Aging, Author Interviews, Geriatrics, Sexual Health / 28.06.2017

MedicalResearch.com Interview with: Dr Hayley Wright BSc(Hons) MSc PhD C.Psychol Research Associate Faculty of Health and Life Sciences, Coventry University Centre for Research in Psychology, Behaviour and Achievement, Coventry University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Last year, we published a study that showed a significant association between sexual activity and cognitive function (Wright & Jenks, 2016). This study showed that sex is linked to cognition, even after we account for other factors such as age, education, and physical and mental wellbeing. One important question that emerged from this study was centred around the role of frequency with which we engage in sexual activity. In the current study (Wright, Jenks & Demeyere, 2017), we found that engaging in sexual activity on a weekly basis is associated with better scores on specific cognitive tasks. (more…)
Author Interviews, Cancer Research, Geriatrics, JAMA, Johns Hopkins / 12.06.2017

MedicalResearch.com Interview with: Nancy Schoenborn, MD Assistant Professor Division of Geriatric Medicine and Gerontology Johns Hopkins University School of Medicine Nancy Schoenborn, MD Assistant Professor Division of Geriatric Medicine and Gerontology Johns Hopkins University School of Medicine MedicalResearch.com: What are the main findings? Response: A lot of cancer screenings are not expected to save lives until up to 10 years later; however, the side effects of the test happen right away. Because of this, clinical guidelines have recommended against routine screening for those patients who will not live long enough to benefit but may experience the potential harm of the test in the short term. However, many patients with limited life expectancy still receive screening and clinicians are worried about how patients would react if they recommended that patients stop screening. This research is important because it is the first study that explores how patients think about the decision of stopping cancer screening and how patients want to talk to their doctors about this issue. Understanding patient perspectives would help improve screening practices and better align recommendations and patient preference. (more…)
Aging, Author Interviews, Geriatrics / 10.06.2017

MedicalResearch.com Interview with: Raya Elfadel Kheirbek, MD, MPH Geriatrician and Palliative Care Physician Washington DC VA Medical Center Associate Professor of Medicine George Washington University School of Medicine and Health Sciences MedicalResearch.com: What is the background for this study? What are the main findings? Response: In the past decade, there has been a shift in the concept of successful aging from a focus on life span to health span. We all want to age gracefully “expecting” optimal health, quality of life and independence. Centenarians are living examples to the progress we have made in health care. They are the best example of successful aging since they have escaped, delayed or survived the major age-related diseases and have reached the extreme limit of human life. However, little is known about Veterans Centenarians’ incidence of chronic illness and its impact on survival. Utilizing the VA Corporate Data Warehouse (CDW), I worked with my colleagues’ researchers and identified 3,351 centenarians who were born between 1910 and 1915. The majority were white men who served in World War II and had no service related disability. The study found that 85 % of all the centenarians had no incidence of major chronic conditions between the ages of 80 and 99 years of age. The data demonstrate that Veteran centenarians tend to have a better health profile and their incidence of having one or more chronic illness is lower than in the general population. (more…)
Author Interviews, Geriatrics, JAMA, Surgical Research / 24.05.2017

MedicalResearch.com Interview with: Cheryl Chia-Hui Chen, RN, DNSc Vice Dean for Student Affairs Professor of Nursing National Taiwan University Nurse Supervisor at National Taiwan University Hospital Taipei, Taiwan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Older patients undergoing abdominal surgery often experience preventable delirium, which greatly influences their postoperative recovery and hospital length of stay. The modified Hospital Elder Life Program (mHELP) utilizes nurses to reduce postoperative delirium and LOS among older patients undergoing abdominal surgery for resection of malignant tumor. The mHELP consisted of 3 protocols: oral and nutritional assistance, early mobilization, and orienting communication, researchers say. Researchers at the National Taiwan University Hospital randomly assigned 377 patients undergoing abdominal surgery for a malignant tumor to an intervention (n = 197) or usual care (n = 180). Postoperative delirium occurred in 6.6 percent of mHELP participants vs 15.1 percent of control individuals (odds of delirium reduced by 56 percent). Intervention group participants received the mHELP for a median of 7 days, and they had a median LOS that was two days shorter (12 vs 14 days). (more…)
Author Interviews, Geriatrics, JAMA, NYU, Primary Care / 22.05.2017

MedicalResearch.com Interview with: Benjamin Han, MD, MPH Assistant professor Departments of Medicine-Division of Geriatric Medicine and Palliative Care, and Population Health NYU Langone Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are an increasing number of older adults being prescribed statins for primary prevention, but the evidence for the benefit for older adults is unclear. Our study finds that in the ALLHAT-LLT clinical trial, there were no benefits in either all-cause mortality or cardiovascular outcomes for older adults who did not have any evidence of cardiovascular disease at baseline.

Author Interviews, Exercise - Fitness, Geriatrics, NEJM, Weight Research / 17.05.2017

MedicalResearch.com Interview with: Dennis T. Villareal, MD Professor of Medicine Division of Endocrinology, Diabetes & Metabolism Baylor College of Medicine Staff Physician, Michael E DeBakey VA Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: The prevalence of obesity in the elderly is rapidly increasing, given that the baby boomers are becoming senior citizens, but we do not know how best to manage obesity in the elderly population. Weight loss is the cornerstone of management for obesity but weight loss in the elderly is controversial because weight loss could cause not only fat loss but also muscle mass and bone mass losses, that could worsen rather than improve frailty. We tested the hypothesis that weight loss plus exercise training, especially resistance training, would improve physical function the most compared to other types of exercise (aerobic training or combined aerobic and resistance training added to diet-induced weight loss). Previous studies especially in younger adults have shown that combining aerobic with resistance exercise could lead to interference to the specific adaptations to each exercise, and thus less gain in strength with combined exercise compared to resistance training alone. On the other hand, contrary to our hypothesis, we found that there was no interference between aerobic and resistance exercise, and the most effective mode to improve physical function and thus reverse frailty was in fact weight loss plus the combination of aerobic and resistance exercise, which was also associated with some preservation of muscle and bone mass.

Author Interviews, End of Life Care, Geriatrics, Medicare, Yale / 04.04.2017

MedicalResearch.com Interview with: Shi-Yi Wang MD, PhD. Department of Chronic Disease Epidemiology Yale School of Public Health New Haven, CT MedicalResearch.com: What is the background for this study? What are the main findings? Response: Care at the end of life is often fragmented and poorly coordinated across different health providers. Multiple transitions in care settings can be burdensome to patients and their families as well as costly to society. Despite these concerns about care transitions in the end of life, we lack contemporary data on the number, timing, and overall pattern of healthcare transitions in the last 6 months of life. This study adds to the extant literature by understanding transition trajectories, national variation of the transitions, and factors associated with transitions. We found that more than 80% of Medicare fee-for-service decedents had at least one health care transition and approximately one-third had ≥ 4 transitions in the last 6 months of life. We produced Sankey diagrams to visualize the sequences of healthcare transitions. The most frequent transition pattern involving at least four transitions: home-hospital-home (or skilled nursing facility)-hospital-healthcare setting other than hospital. There was substantial geographic variation in healthcare transitions in the United States. We found that several factors were associated with a significantly increased risk of having multiple transitions, including female gender, blacks, residence in lower income areas, presence of heart disease or kidney disease.

Abuse and Neglect, Cost of Health Care, Geriatrics / 25.03.2017

MedicalResearch.com Interview with: Sheila Eckenrode RN, CPHQ Quality Improvement Consultant The New England QIN-QIO Qualidigm, Wethersfield, Connecticut MedicalResearch.com: What is the background for this study? Response: Post-acute care has become a focus for improving quality and cost effectiveness of healthcare in the United States. Changes in Medicare payment systems such as bundled payments and the emergence of Affordable Healthcare Organizations will most likely lead to expansion of post-acute care services and decrease in acute care hospitalizations. Approximately 30% of hospitalized Medicare beneficiaries were referred to home health care at discharge in 2012. In 2013, home health agencies served 3.5 million beneficiaries with Medicare paying $18 billion for these services. Home health care has been emphasized under the Improving Medicare Post-Acute Care Transformation Act of 2014 to provide and improve care at individual patient and community levels. In anticipation of increasing utilization of home care services, our study aimed to demonstrate the overall growth in home care availability as well as identify geographical variation and potential gaps in service.

Aging, Author Interviews, Geriatrics, Karolinski Institute, Social Issues / 14.03.2017

MedicalResearch.com Interview with: Dr. Karin Modig, PhD Institute of Environmental Medicine,Epidemiology Karolinska Institute MedicalResearch.com: What is the background for this study? Response: The background to the study was that even though it is established that parents live longer than non-parents the underlying mechanisms are not clear. And it was not known how the association changed with the age of the parents. We hypothesize that if social support is one mechanism – the association between having children and the death risk of parents-non-parents would increase with age of the parents, when health starts to deteriorate and the need of support increases.

Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Geriatrics, Heart Disease, Stroke / 26.02.2017

MedicalResearch.com Interview with: Ariela Orkaby, MD, MPH Geriatrics & Preventive Cardiology Associate Epidemiologist Division of Aging, Brigham and Women's Hospital Instructor in Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Atrial Fibrillation is a common heart rhythm that affects 1 in 25 adults over age 60 and 1 in 10 adults over age 80. The feared consequence of atrial fibrillation is stroke, leading to the prescription of blood thinning medications (anticoagulants such as warfarin) to prevent strokes. However, there is an underutilization of these life-saving medications in older adults, and particularly in those who have dementia. In part, this is due to a lack of research and inclusion of older adults with dementia in prior studies. In this study, we used clinical Veterans Administration data, linked to Medicare, to follow 2,572 individuals over age 65 who had atrial fibrillation and until a diagnosis of dementia. The average age was 80 years, and 99% were male. We found that only 16% remained on warfarin. We used statistical methods to account for reasons why a patient would or would not be treated with warfarin and found that those who continued to take warfarin had a significantly lower risk of stroke (HR 0.74, 95% Confidence interval 0.54- 0.99, p=0.47) and death (HR 0.72, 95% CI 0.60-0.87, p<0.01) compared to those who did not continue to take warfarin, without an increased risk of bleeding.

MedicalResearch.com Interview with: Olga Khavjou RTI International MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cardiovascular disease (CVD) is the leading cause of death in the United States and is one of the costliest chronic diseases. As the population ages, CVD costs are expected to increase substantially. To improve cardiovascular health and control health care costs, we must understand future prevalence and costs of CVD. In 2015, 41.5% (more than 100 million people) of the U.S population was estimated to have some form of CVD. By 2035, the number of people with CVD is projected to increase to over 130 million people, representing a 30% increase in the number of people with CVD over the next 20 years. Between 2015 and 2035, real total direct medical costs of CVD are projected to more than double from $318 billion to $749 billion and real indirect costs (due to productivity losses) are projected to increase from $237 billion to $368 billion. Total costs (medical and indirect) are projected to more than double from $555 billion in 2015 to $1.1 trillion in 2035. (more…)
Aging, Author Interviews, Depression, Geriatrics, Hip Fractures / 16.01.2017

MedicalResearch.com Interview with: Sanna Torvinen-Kiiskinen MSc (Pharm.), PhD student, Kuopio Research Centre of Geriatric Care and School of Pharmacy University of Eastern Finland MedicalResearch.com: What is the background for this study? Response: Antidepressants are widely used among elderly persons, especially persons with Alzheimer’s disease. They are used not only for treatment for major depression, but for treatment of anxiety, insomnia and chronic pain as well as behavioral symptoms caused by dementia. However, antidepressants, as well as other psychotropic drugs, may cause sedation, confusion, orthostatic hypotension and hyponatremia, which increase the risk of falling and fractures. Because of changes in pharmacodynamics and pharmacokinetics due to aging, older persons are at the higher risk of those adverse events. The aim of our study was to investigate whether antidepressant use is associated with an increased risk of hip fracture among community-dwelling persons with and without Alzheimer’s disease. (more…)

MedicalResearch.com Interview with: Leigh Purvis, MPA AARP PPI Director of Health Services Research MedicalResearch.com: What is the background for this study? What are the main findings? Response: This report is part of an ongoing series that AARP has been publishing since 2004. The report focuses on brand name prescription drugs that are widely used by older Americans and found that, on average, their retail prices increased almost 130 times faster than general inflation in 2015. The report also found that the average annual cost for one brand name medication used on a chronic basis was more than $5,800 in 2015, almost $1,000 higher than the average annual cost of therapy in 2014.

Author Interviews, Electronic Records, Geriatrics, Pharmacology / 29.11.2016

MedicalResearch.com Interview with: Jashvant Poeran MD PhD Assistant Professor Dept. of Population Health Science & Policy Icahn School of Medicine at Mount Sinai New York, NY MedicalResearch.com: What is the background for this study? Response: Falls are an important patient safety issue among elderly patients and may lead to extended hospitalization and patient harm. Particularly important in elderly patients are high risk drugs such as sleep medications which are known to increase fall risk and should be dosed lower in elderly patients. In this study we looked at patients aged 65 years or older who fell during hospitalization. We found that in 62%, patients had been given at least one high risk medication that was linked to fall risk, within 24 hours before their fall. Interestingly, we found that also a substantial proportion of these medications were given at doses higher than generally recommended for elderly patients. (more…)
Author Interviews, Breast Cancer, Geriatrics, Radiation Therapy / 23.11.2016

MedicalResearch.com Interview with: Emily C. Daugherty, MD Upstate Medical University Radiation Oncology Resident, PGY-4 MedicalResearch.com: What is the background for this study? Response: Adjuvant radiation following breast conserving surgery has been well established in the management of early-stage breast cancer as it has been shown to decrease the incidence of ipsilateral breast tumor recurrences and also reduce breast cancer mortality. Large prospective trials have shown for elderly patients with favorable, ER positive pathology, omission of radiation after lumpectomy can be considered. However, women with ER negative disease were typically not included in these trials and given their higher risk for relapse as well as lack of effective endocrine therapy, we hypothesized that adjuvant radiation would benefit women over 70 years with early-stage, ER negative tumors.

Author Interviews, Emory, Exercise - Fitness, Geriatrics, Heart Disease, Lifestyle & Health / 18.11.2016

MedicalResearch.com Interview with: Vasiliki Georgiopoulou MD MPH PhD Assistant Professor of Medicine (Cardiology) Emory University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although existing evidence suggests that more exercise capacity is associated with lower risk of CV disease and death, we don’t know whether more exercise capacity would lead to lower risk for heart failure also. This would be especially important for older adults, who are the group with the highest risk to develop heart failure. We used the data of a cohort study to test this association. The exercise capacity was evaluated by a walking test that is easy to perform – the long-distance corridor walk test. We observed that older adults who were able to complete the test had the lowest risk to develop heart failure and the lowest mortality rates, when compared with those who were not able to complete the test and those who could not do the test for medical reasons. We also observed that changes in exercise capacity 4 years later did not predict subsequent heart failure or mortality – perhaps because less fit older patients had already developed heart failure or had died.

Author Interviews, Emergency Care, Geriatrics, Infections / 15.11.2016

MedicalResearch.com Interview with: John P. Haran, MD Assistant Professor Department of Emergency Medicine University of Massachusetts Medical School UMass Memorial Medical Group Worcester, MA MedicalResearch.com: What is the background for this study? Response: In 2014, the Infectious Disease Society of America (IDSA) updated their guidelines for the management of skin and soft tissue infection in response to high MRSA infection rates as well as high treatment failure rates for skin and soft tissue infections. Greater than 1 in 5 patients treated for a skin abscess will fail initial treatment. Historically antibiotics have been shown to be unnecessary in the treatment of uncomplicated purulent infections. This notion has been recently challenges when authors published a randomized control trial using trimethoprim-sulfamethoxazone in the NEJM that demonstrated a minimal increase in cure rates for outpatient treatment of uncomplicated skin purulent skin infections. In this study they did not follow IDSA-guidelines nor model or stratify their analysis. It is possible their findings may be due to at-risk patient groups that did not receive antibiotics. Many widely used clinical decision rules incorporate age into their decision algorithms, however the IDSA did not do this with their recent guidelines. (more…)
Author Interviews, Geriatrics, Medical Imaging, MRI, Weight Research / 08.11.2016

MedicalResearch.com Interview with: Fatemeh Mokhtari Medical Imaging PhD Student VT-WFU SBES MedicalResearch.com: What is the background for this study? What are the main findings? Response: The objective of this study was to use baseline anatomical brain MRI scans to prospectively predict weight loss success following an intensive lifestyle intervention. In the study, 52 participants, age 60 to 79, were recruited from the Cooperative Lifestyle Interventions Programs II (CLIP-II) project. The participants were overweight or obese (BMI greater than 28 and less than 42) and had a history of either cardiovascular disease or metabolic syndrome. All participants had a baseline MRI scan, and then were randomized to one of three groups – diet only, diet plus aerobic exercise training or diet plus resistance exercise training. The goal of the 18-month diet and exercise program was a weight loss of 7 to 10 percent of body mass. Basic brain structure information garnered from the MRIs was classified using a support vector machine, a type of computerized predictive algorithm. Specifically, we trained a computational predictive model which mapped each subject’s brain scan to weight loss performance. Predictions were based on baseline brain gray and white matter volume from the participants’ MRIs and compared to the study participants’ actual weight loss after the 18 months. The accuracy of the model was then tested, and our prediction algorithms were 78% accurate in predicting successful weight loss. Brain gray matter volume provided higher prediction accuracy compared with white matter and the combination of the two outperformed either one alone. (more…)
Alzheimer's - Dementia, Author Interviews, Critical Care - Intensive Care - ICUs, End of Life Care, Geriatrics, JAMA / 12.10.2016

MedicalResearch.com Interview with: Joan M. Teno, MD, MS Department of Gerontology and Geriatrics, Cambia Palliative Care Center of Excellence University of Washington Medicine Seattle, Washington MedicalResearch.com: What is the background for this study? Response: An important challenge for our health care system is effectively caring for persons that high-need, high-cost — persons afflicted with advanced dementia and severe functional impairment are among these persons, with substantial need and if hospitalized in the ICU and mechanically ventilated are high cost patients, who are unlikely to benefit from this level of care and our best evidence suggest the vast majority of persons would not want this care. In a previous study, we interviewed families of advance dementia with 96% starting the goals of care are to focus comfort. Mechanical ventilation in some cases may be life saving, but in cases such as those with advanced dementia and severe functional impairment, they may result in suffering without an improvement in survival.

MedicalResearch.com Interview with: Thomas M. Gill, M.D. Humana Foundation Professor of Geriatric Medicine Professor of Medicine, Epidemiology & Investigative Medicine Director, Yale Program on Aging/Pepper Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Maintaining independent mobility is an important goal of clinical medicine and public health, especially among older persons, who are at the greatest risk for disability. By adopting a walking routine and other moderate physical activities, older adults can recover from a major disability more quickly, and maintain their independence over time. (more…)
Annals Internal Medicine, Author Interviews, Brigham & Women's - Harvard, Colon Cancer, Geriatrics / 27.09.2016

MedicalResearch.com Interview with: Xabier Garcia-De-Albeniz MD PhD Research Associate Department of Epidemiology Harvard T.H. Chan School of Public Health Mongan Institute for Health Policy Massachusetts General Hospital MedicalResearch.com: What is the background for this study? Response: Randomized controlled trials are considered the gold standard to inform health care delivery. Unfortunately, no randomized controlled trials of screening colonoscopy have been completed. Ongoing trials exclude persons aged 75 or older, and will not have mature results before 2025. However, healthy persons older than 75 may live long enough to benefit from colorectal cancer (CRC) screening. The Medicare program reimburses screening colonoscopy without an upper age limit since the year 2001. We used the extensive experience of Medicare beneficiaries to evaluate the effectiveness and safety of screening colonoscopy. (more…)
Author Interviews, Dermatology, Geriatrics, Melanoma / 21.09.2016

MedicalResearch.com Interview with: José Antonio Avilés-Izquierdo, PhD Department of Dermatology Hospital Gregorio Marañón Madrid, Spain MedicalResearch.com: What is the background for this study? Response: Melanoma is responsible for most of skin cancer-related deaths and the cancer with the highest cost per death and the highest lost of productive-life years in Europe. Despite the importance on early diagnosis of cutaneous melanoma, there are few studies analyzing the reasons that lead patients with melanoma to consult. The impact on prognosis in patients with melanoma according to who first detects melanoma have not been established. (more…)
Author Interviews, Frailty, Geriatrics, Lancet, Technology / 19.09.2016

MedicalResearch.com Interview with: Anat Mirelman, PhD Director- Laboratory of Early Markers of Neurodegeneration (LEMON) Center for the study of Movement , Cognition and Mobility (CMCM) Department of Neurology Tel Aviv Sourasky Medical Center Sackler School of Medicine, Tel Aviv University Tel Aviv 64239, Israel MedicalResearch.com: What is the background for this study? What are the main findings? Response: The main aim of this research was to evaluate the efficacy of using a motor cognitive training using virtual reality in reducing fall frequency and fall risk in older adults. Falls are a leading cause of morbidity and mortality in older adults. The prevalence of falls is huge, with one out of every 3 adults aged 65 years or older will fall at least once per year, with approximately half of these fallers suffering multiple falls in this period . These statistics are even higher in neurodegenerative conditions such as in Parkinson’s disease and in people with cognitive impairments. For example, studies have shown that as much as 80% of people with Parkinson’s disease fall each year. So many older adults are falling. The consequences of falls are huge. The most dramatic result is hip fracture. But this is relatively rare. However, even in the absence of a fracture or other injury, falls often lead to fear of falling, social isolation, and depression, which in turn often leads to inactivity, muscle weakness, impaired balance and gait, more falls, more social isolation. In other words, falls often start a vicious cycle, which has many important negative health consequences. Falls are associated with morbidity and mortality and they also have a huge economic impact. In many western countries, 1-2% of healthcare dollars are spent on falls. For many years, age-associated changes in muscle strength, balance and gait were viewed as the key factors that contribute to the risk of falls. However, more recently, we and others showed that certain aspects of cognition are also critical to safe ambulation. For example people with AD often fall, almost to the same amount as people with PD, highlighting the cognitive component of falls. This makes sense intuitively if we Imagine the cognitive skills we need just to cross a busy intersection. These tasks require executive function, specially, planning, the ability to avoid obstacles, and the ability to perform two or more tasks at the same time. (more…)
Accidents & Violence, Author Interviews, CDC, Cost of Health Care, Frailty, Geriatrics / 30.08.2016

MedicalResearch.com Interview with: Elizabeth Burns, MPH Health Scientist, Division of Unintentional Injury Prevention National Center for Injury Prevention and Control CDC MedicalResearch.com: What is the background for this study? Response: Falls are the leading cause of both fatal and non-fatal injuries among Americans aged 65 and older. In 2000, the direct cost of falls were estimated to be $179 million for fatal falls and $19 billion for non-fatal falls. Fall injuries and deaths are expected to rise as more than 10,000 Americans turn 65 each day. Within the next 15 years, the U. S. population of older Americans is anticipated to increase more than 50%, with the total number of older adults rising to 74 million by 2030. (more…)
