Newswise — Adding further to its expanding scope of pediatric and neurological services, NYU Lutheran Medical Center is now making it easier for families to identify and treat neurological and psychological issues that could impair childhood development. The development of the brain in childhood has life-long effects on overall health and well-being, including cognition, learning ability, behavior, and social skills. When an injury involving the brain or the possibility of a developmental delay is presented early in life, it needs to be identified and treated to prevent future problems into adulthood. Gianna Locascio, PsyD, NYU Lutheran’s new pediatric neuropsychologist, has devoted her career to helping families identify these conditions and develop appropriate treatment plans for a healthy future. “When I evaluate a child, I create a neurocognitive profile to identify strengths and weaknesses in all areas of cognitive function,” says Locascio. Specifically, she looks at intellect, attention, concentration, memory, motor coordination, personality, language skills, and other factors. Planning, organizing, and shifting attention from one task to another efficiently also are key areas she assesses. Once an evaluation is completed, Locascio often refers patients to an appropriate, conveniently located therapist or specialist within the NYU Langone health system, and continues to monitor the child’s progress through development. Over time, she may update her comprehensive recommendations to maximize the child’s functioning at home and in social, community, and academic settings. “The key to providing comprehensive care is to ensure that the patient is healthy and thriving in a range of areas,” says Steven L. Galetta, MD, the Philip K. Moskowitz, MD, Professor and Chair of the Department of Neurology at NYU Langone Medical Center. “Monitoring progress and adjusting care recommendations based on lifestyle changes is important in all medical practices, but particularly neurological care. Dr. Locascio is a valuable addition to NYU Langone health system’s neuropsychological testing services and will play an important role in the comprehensive approach at NYU Lutheran.” Locascio specializes in cognitive issues related to traumatic brain injury, concussion, stroke, epilepsy, brain tumors, encephalitis, cerebral palsy, sickle cell disease, attention deficit hyperactivity disorder, anxiety, depression, Down syndrome, autism spectrum, spina bifida, Sturge-Weber syndrome, and other childhood and adolescent disorders. Her passion for pediatric neuropsychology is rooted in her love of science and desire to help young people develop into healthy adults. “It’s very rewarding to work with children and adolescents,” she says. “There are so many ways to help maximize function. I have seen patients go on to extraordinary progress.” Locascio is the only pediatric neuropsychologist in Brooklyn board certified in both clinical neuropsychology and pediatric neuropsychology. An undergraduate alumna of Lafayette College, she earned her master’s degree and doctorate from Rutgers University with dual concentration in school psychology and neuropsychology. She completed a fellowship in neuropsychology at Kennedy Krieger Institute at Johns Hopkins School of Medicine.

Newswise — New York and Boston — Improving dietary resilience and better integration of nutrition in the health care system can promote healthy aging and may significantly reduce the financial and societal burden of the “silver tsunami.” This is the key finding of a “Nutritional Considerations for Healthy Aging and Reduction in Age-Related Chronic Disease,” a new paper initiated under the auspices of the Sackler Institute for Nutrition Science Working Group on Nutrition for Aging Population, and published in Advances in Nutrition. By 2050, the number of persons aged 80 years old and over will reach 392 million, about three times the 2013 population. According to the report, an increasingly large portion of the population will be vulnerable to nutritional frailty, a state commonly seen in older adults, characterized by sudden significant weight-loss and loss of muscle mass and strength, or an essential loss of physiologic reserves, making the person susceptible to disability. Ironically, while increasing numbers of older adults are obese, many are also susceptible to nutritional frailty and, as a result, age-related diseases including sarcopenia, cognitive decline, and infectious disease. The review concludes that exploring dietary resilience, defined as a conceptual model to describe material, physical, psychological and social factors that influence food purchase, preparation and consumption, is needed to better understand older adults’ access to meal quality and mealtime experience. A recent model to frame food intake includes the addition of more randomized clinical trials that include older adults with disease and medication. This will help to identify their specific nutrient needs, biomarkers to understand the impact of advancing age on protein requirements, skeletal muscle turnover and a re-evaluation of how BMI guidelines are used. “A nutritional assessment model that takes into consideration the effect of aging on muscle mass, weight loss and nutrient absorption is crucial to overall wellness in our elderly population,” said Gilles Bergeron, Ph.D., executive director, The Sackler Institute for Nutrition Science at the New York Academy of Sciences, New York, NY. “However, nutrition recommendations are usually based on that of a typical healthy adult, and fail to consider the effect of aging on muscle mass, weight loss, and nutrient absorption and utilization.” Simin Nikbin Meydani, D.V.M., Ph.D., director of the Nutritional Immunology Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, Boston, MA concurs. “Much greater emphasis needs to be placed on prioritizing research that will fill the knowledge gaps and provide the kind of data needed by health and nutrition experts if we’re going to address this problem,” she said. “There also needs to be more education about on-going nutritional needs for those involved with elder-care – not only in a clinical setting, but also for family members who are responsible for aging adults.” Additional authors of this review are Julie Shlisky, Ph.D., consultant at The Sackler Institute for Nutrition Science; David E.

Newswise — AMES, Iowa – If your New Year’s resolution was to exercise more in 2017, chances are you’ve already given up or you’re on the verge of doing so. To reach your goal, you may want to consider joining a gym, based on the results of a new study from a team of Iowa State University researchers. Duck-chul (DC) Lee, an assistant professor of kinesiology and corresponding author of the paper, says the study found people who belonged to a health club not only exercised more – for both aerobic activity and strength training – they also had better cardiovascular health outcomes. Those health benefits were even greater for people who had a gym membership for more than a year, Lee said. The research is published in the journal PLOS ONE. “It’s not surprising that people with a gym membership work out more, but the difference in our results is pretty dramatic,” Lee said. “Gym members were 14 times more aerobically active than non-members and 10 times more likely to meet muscle-strengthening guidelines, regardless of their age and weight.” The results were similar in both men and women. It’s recommended that adults get 150 minutes of moderate or 75 minutes of vigorous aerobic activity each week, such as brisk walking or running. The Physical Activity Guidelines also suggest two days of weight lifting or other muscle-strengthening activities. Despite strong evidence of the health benefits, only half of Americans are getting enough aerobic activity and about 20 percent meet the guidelines for strength training. Iowa State researchers found 75 percent of study participants with gym memberships, compared to 18 percent of non-members, met the guidelines for both types of activity. In fact, the majority of those who went to a health club exceeded standards and spent 300 minutes or more running, biking or doing some type of cardio workout each week. That adds up to nearly six hours of additional activity, compared to non-members. Gym members overall had a more active lifestyle. Researchers say members were just as active outside the gym and in their daily lives, which combined contributed to better health outcomes. Here are a few of the results for members: • Lower odds of being obese – weight loss is a main reason for joining a gym• Smaller waist circumference – about 1.5 inches less for men and a similar trend for women• Lower resting heart rate – about five beats lower than non-members• Higher cardiorespiratory fitness – this measures heart strength, lung function, blood circulation and muscle mass Elizabeth Schroeder, lead author and a former Iowa State graduate student, says while most people join a gym to lose weight, the research shows the many benefits of exercise. “Cardiovascular disease is the leading cause of death for individuals in the U.S. As our paper shows, a health club membership is associated with more favorable cardiovascular health,” Schroeder said. “I hope the results help people be more active, potentially at a health club where they can easily perform resistance exercise, and see that exercise may help prevent cardiovascular disease.” This is also one of the first studies to measure weight lifting and resistance exercise. Lee says this type of activity is beneficial because it builds muscle mass, which burns more energy and lowers the risk of obesity and the risk of sarcopenia for older adults. Researchers did not ask participants if they spend time at the gym running on a treadmill, riding a bike, attending a group fitness class or other activity. However, Warren Franke, a co-author and professor of kinesiology, says health clubs offer a variety of options and benefits for people who are new to exercise. Franke is director of Iowa State’s Exercise Clinic. “By joining a quality fitness facility, a new exerciser will be around like-minded people and have access to professionals who can help them be successful,” Franke said. “Access to quality exercise equipment, social support and even the financial commitment may help spur someone to continue exercising. Not all facilities are the same, so it’s important to find the ‘right’ fit.” Incentivizing workouts Most people spend much of their day sitting at a desk, and do little heavy lifting to create resistance against their muscles. Increasing activity levels lowers the risk for diseases such as Type 2 diabetes and cardiovascular disease, Lee said. However, only 18 percent of Americans have a gym membership. Based on the research results, incentives to boost membership could be beneficial, Lee said. Several companies have on-site workout facilities for employees or provide some form of reward for going to the gym. Greg Welk, a co-author and professor of kinesiology, says efforts to increase these opportunities not only improves employee health, but also reduce sick days and lower insurance costs. As a coordinator of the ISU’s Wellness Works, Welk provides companies with the tools and support to implement effective wellness programming. “Access to fitness facilities can provide employees with an incentive to take responsibility and adopt regular habits of physical activity,” Welk said. “A fitness center can promote improved fitness, but employees may also need support for eating habits, managing stress and other health needs.” Researchers say it’s important to note that some data for the study were collected while people were at the gym, which would exclude people who have a membership, but are not using it. It is also a cross-sectional study, so researchers cannot directly state a cause and effect. SEE ORIGINAL STUDY
STEROID ORIGINALLY DISCOVERED IN THE DOGFISH SHARK ATTACKS PARKINSON’S-RELATED TOXIN IN ANIMAL MODEL
Newswise — WASHINGTON — A synthesized steroid mirroring one naturally made by the dogfish shark prevents the buildup of a lethal protein implicated in some neurodegenerative diseases, reports an international research team studying an animal model of Parkinson’s disease. The clustering of this protein, alpha-synuclein (α-synuclein), is the hallmark of Parkinson’s and dementia with Lewy bodies, suggesting a new potential compound for therapeutic research. The finding, published online in Proceedings of the National Academy of Sciences, also demonstrated that the synthesized steroid, called squalamine, reduced the toxicity of α-synuclein clumps that already existed. The pre-clinical study results show that squalamine prevents and eliminates α-synuclein build up inside neurons by unsticking the protein from the inner wall of nerve cells, where it clings and builds up into toxic clumps, researchers say. The animal model used for this study, C. elegans, is a nematode worm genetically engineered to produce human α-synuclein in its muscles. As these worms age, α-synuclein builds up within their muscle cells causing cell damage and paralysis. “We could literally see that squalamine, given orally to the worms, did not allow α-synuclein to cluster, and prevented muscular paralysis inside the worms,” says the study’s co-senior author, Michael Zasloff, MD, PhD, professor of surgery and pediatrics at Georgetown University School of Medicine and scientific director of the MedStar Georgetown Transplant Institute.The study’s lead author, graduate student Michele Perni, and other co-senior authors, Michele Vendruscolo, PhD and Christopher M. Dobson, DPhil, ScD, are from Cambridge University. An additional co-senior author, Adriaan Bax, PhD, is from National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health (NIH) in Bethesda, Maryland. Scientists from the Netherlands, Italy and Spain also contributed to this research. Zasloff, an expert in innate immune systems, has been studying squalamine for more than 20 years. He discovered it in dogfish sharks in 1993 and synthesized it in 1995 (in a process that does not involve use of any natural shark tissue). His research, as well as that by other scientists, has established antiviral and anticancer properties of the compound. This is the first study to show it has neurological benefits in in vivo models of Parkinson’s. In Parkinson’s disease, α-synuclein, a normal protein present within the nervous system, forms toxic clumps that damage and ultimately destroy the neurons in which they form. Considerable research has been directed at discovering compounds that prevent the formation of these masses, thereby representing potential therapeutics for Parkinson’s disease. In this study, the researchers demonstrated in a series of in vitro experiments that squalamine, a positively charged molecule with a high affinity for negatively charged membranes, could literally “kick off” α-synuclein from negatively charged membranes, where the protein binds, preventing the formation of the toxic clumps. The research team also showed that squalamine could protect healthy human neuronal cells from being damaged by exposure to pre-formed toxic masses of α-synuclein, by preventing them from adhering to the outer membrane of the neuronal cells. The researchers then extended these studies to a living system, C. elegans, a well-studied model of Parkinson’s disease. “Orally administered squalamine prevented the formation of toxic α-synuclein clumps in this complex animal, and rescued the animal from loss of mobility,” Zasloff explains. “This experiment taught us that the basic mechanism demonstrated in vitro achieved the anticipated outcome in an animal.” The study's co-senior author, Professor Christopher Dobson, DPhil, Master of St John's College, University of Cambridge says, "Squalamine gives us a first generation compound, which we believe that we can incrementally improve through further studies of the underlying mechanism by which it affects the aggregation of alpha-synuclein." Zasloff says a clinical trial with squalamine in Parkinson’s disease is being planned. “Squalamine could be especially suited to work in the gut with the goal of treating the gastrointestinal symptoms of Parkinson’s,” he adds. Zasloff is the inventor on a patent application that has been filed related to the technology described in this paper.

Newswise — Many infectious diseases are one and done; people get sick once and then they are protected from another bout of the same illness. For some of these infections – chickenpox, for example – a small number of microbes persist in the body long after the symptoms have gone away. Often, such microbes can reactivate when the person’s immunity has waned with age or illness, and cause disease again. Now, researchers at Washington University School of Medicine in St. Louis studying leishmaniasis, a tropical disease that kills tens of thousands of people every year, believe they have found an explanation for the seemingly paradoxical connection between long-term infection and long-term immunity. By constantly reminding the immune system what the parasite that causes leishmaniasis looks like, a persistent infection keeps the immune system on alert against new encounters, even while it carries the risk of causing disease later in life, the researchers found. Understanding how persistent infection leads to long-term immunity could help researchers design vaccines and treatments for persistent pathogens. The research is published the week of Jan. 16 in Proceedings of the National Academy of Sciences. “People had been thinking of the role of the immune system in persistent infection in terms of mowing down any pathogens that reactivate in order to protect the body from disease,” said Stephen Beverley, PhD, the Marvin A. Brennecke Professor of Molecular Microbiology and the study’s senior author. “What was often overlooked was that in the process of doing this, the immune system is constantly being stimulated, which potentially promotes protection against future illness.” In a persistent infection, a small population of microbes remains in the body long after the patient’s symptoms are gone. In addition to the parasite that causes leishmaniasis, many kinds of microbes can cause persistent infections, including bacteria responsible for tuberculosis and viruses that lead to herpes and chickenpox. “A lot of pathogens cause persistent infections, but the process was something of a black box,” said Michael Mandell, PhD, the first author on the study. Mandell, who conducted the research for the study as a graduate student, is now an assistant professor at the University of New Mexico. “Nobody really knew what was going on during persistent infection and why it was associated with immunity.” To find out, Mandell and Beverley studied Leishmania, a group of parasites that cause ulcers on the skin and can infect internal organs. An estimated 250 million people worldwide are infected with the parasite – found in tropical areas – and 12 million have active disease. The disease can be disfiguring or even fatal, but once a person is infected, he or she is protected from getting sick a second time. In other words, infection confers long-term immunity. People are thought to continue to harbor the parasite at low numbers for years after they recover from the disease, including some people treated with anti-leishmania drugs. This persistence may be to the benefit of their human hosts; studies in mice have shown that completely clearing the parasite often makes the animals susceptible to another bout of disease if they encounter the parasite again. Studying mice, the researchers used fluorescent markers to distinguish different types of mouse cells, and found that most of the parasites live in immune cells capable of killing the parasites. Yet, despite their dangerous homes, the parasites appeared normal in shape and size. Further, most of the parasites continued to multiply, yet the total number of parasites stayed the same over time. “Mike Mandell called it the ‘Jimmy Hoffa effect’ because we couldn’t locate the body,” Beverley said. “We were unable to show directly that the parasites were being killed. But some of them must have been dying because the numbers weren’t going up.” The immune cells that housed the parasites are responsible for killing pathogens and activating a more robust immune response. It is this process – the ongoing multiplication and killing of parasites – that the researchers believe underlies the long-term immunity associated with persistent infection, and thus explains why people typically can’t get sick with the same pathogen twice. “It seems that our immunologic memory needs reminding sometimes,” Mandell said. “As the persistent parasites replicate and get killed, they are continually stimulating the immune system, keeping it primed and ready for any new encounters with the parasite.” These findings suggest that there are benefits as well as dangers to persistent infection, and, for some organisms at least, developing a vaccine that elicits life-long immunity might require a live vaccine that has the ability to persist without sickening people. “Usually scientists design vaccines to get sterilizing immunity. They’re trying to just kill all the bugs,” Beverley said. “But what you really need is protection against the pathologic consequences of the disease, not necessarily sterilizing immunity. For some of these organisms, solid, long-term protection may come at the price of persistent infection.”
Newswise — An international collaboration led by clinical researchers at the Wellcome Trust Sanger Institute has shown proof-of-concept that truly personalised therapy will be possible in the future for people with cancer. Details of how a knowledge bank could be used to find the best treatment option for people with acute myeloid leukaemia (AML) are published today in Nature Genetics. AML is an aggressive blood cancer that develops in bone marrow cells. Earlier this year, the team reported there are 11 types of AML, each with distinct genetic features. Now they report how a patient's individual genetic details can be incorporated into predicting the outcome and treatment choice for that patient. They built a knowledge bank using data from 1,540 patients with AML who participated in clinical trials in Germany and Austria, combining information on genetic features, treatment schedule and outcome for each person. From this, the team developed a tool that shows how the experience captured in the knowledge bank could be used to provide personalised information about the best treatment options for a new patient. There are two major treatment options for young patients with AML - a stem cell transplant or chemotherapy. Stem cell transplants cure more patients overall but up to one in four people die from complications of the transplant and a further one in four experience long-term side effects. Weighing up the benefits of better cure rates with transplant against the risks of worse early mortality is a harrowing decision for patients and their clinicians. The team showed that these benefits and risks could be accurately calculated for an individual patient, enabling therapeutic choices to become personalised. The team estimates that up to one in three patients would be prescribed a different treatment regimen using the tool compared with current practice. In the long term they hope the tool could spare one in ten young AML patients from a transplant while maintaining overall survival rates. Senior author Dr Peter Campbell of the Wellcome Trust Sanger Institute said: "The knowledge bank approach makes far more detailed and accurate predictions about the likely future course of a patient with AML than what we can make in the clinic at the moment. Current guides use a simple set of rules based on only a few genetic findings. For any given patient, using the new tool we can compare the likely future outcomes under a transplant route versus a standard chemotherapy route - this means that we can make a treatment choice that is personally tailored to the unique features of that particular patient." The tool is currently available for scientists to use in research but needs further testing before it can be used to prescribe treatments in AML clinics. Lead author Dr Moritz Gerstung of the European Bioinformatics Institute said: "It has long been recognised that cancer is a complex genetic disease. Our study provides an example of how detailed genetic and clinical information can be rationally incorporated into clinical decisions for individual patients. We tested this philosophy in one type of leukaemia, but the concept could theoretically be applied in other cancers with difficult clinical decisions as well. Our analysis reveals that knowledge banks of up to 10,000 patients would be needed to obtain the precision needed for routine clinical application." Using large scale genetic studies as a source to predict the best treatment option for future patients is an idea that Genomics England is trying to build alongside similar programmes around the world, such as the National Institutes of Health Precision Medicine Initiative in the US. The authors believe this paper is a step towards validation of genetic techniques as a route to personalised medicine. Co-senior author Dr Hartmut Döhner of University of Ulm said: "Building knowledge banks is not easy. To get accurate treatment predictions you need data from thousands of patients and all tumour types. Furthermore, such knowledge banks will need continuous updating as new therapies become approved and available. As genetic testing enters routine clinical practice, there is an opportunity to learn from patients undergoing care in our health systems. Our paper gives the first real evidence that the approach is worthwhile, how it could be used and what the scale needs to be." ###
Newswise — New Brunswick, N.J. - Cervical cancer is almost always caused by the high-risk types of the human papillomavirus (HPV), which nearly every sexually active person will be exposed to in their lifetime. People with healthy immune systems are able to clear the virus, but when the high risk strains “hijack” or infect specific cells of the cervix it can lead to abnormal cell growth and precancerous changes. Over time and with persistent infection, this leads to cervical cancer. HPV infection can also lead to penile, anal and throat and mouth cancers. Unfortunately, according to the Centers for Disease Control and Prevention (CDC), incidence rates of HPV-associated cancers have continued to rise, with approximately 39,000 new HPV-associated cancers diagnosed each year in the United States. People who smoke or have lowered immune systems also have increased risk of developing HPV-related cancers. How is it prevented? HPV infection and therefore cervical cancer can be prevented by vaccination. There are now two FDA vaccines approved for males and females between ages nine and 26, and according to the latest recommendations from the CDC, all children between nine and 13 should complete the vaccine series. Children younger than 15 should receive two doses of the vaccine six months apart and those over age 15 should complete a three-dose series. Rutgers Cancer Institute of New Jersey is joining with the nation’s 68 other National Cancer Institute-designated cancer centers in supporting these newly revised recommendations. Keep in mind, for a woman, vaccination does NOT mean she should refrain from receiving a routine gynecological screening known as a Pap smear since the vaccine does not 100 percent guarantee against the development of cervical cancer. How is it detected? Pap smears detect precancerous changes that occur in cells and also can now test for HPV infection. The American Congress of Obstetricians and Gynecologists recommends that women begin annual screening for cervical cancer at age 21. A woman should consult with her doctor about the frequency of screening, as it depends on age, results from prior testing, and other health factors.Symptoms are also important for detection. These can include abnormal vaginal bleeding, discharge, bleeding after intercourse, or back pain. A woman should seek care if she develops any of these warning signs as well as maintain routine and appropriate screenings with her gynecologist. How is it treated? Precancerous changes of the cervix are treated with simple procedures. Treatment can prevent precancerous changes from becoming cervical cancer. Early stage cervical cancer is curable with surgery. Remember, by quitting smoking, vaccinating against HPV, undergoing regular Pap smears and protecting yourself against sexually-transmitted diseases, you can help reduce your risk to developing cervical cancer.

Newswise — Alcohol use disorders (AUDs) develop with time and in stages. Following the initiation of drinking, some people progress to problem drinking, and then develop a “cluster” of specific problems to comprise an AUD. However, not all stages of AUD development have been studied equally. This report examines high-risk families to understand underlying influences across multiple stages of AUD development. Researchers scrutinized four transitions in AUD development using data on adolescents and young adults from high-risk families: time to first drink, first drink to first problem, first drink to first diagnosis, and first problem to first diagnosis. Potential influences included parental AUD, parental separation, peer substance use, ever use of marijuana by offspring, trauma exposures, and different psychopathologies across transitions. Results showed that significant influences across all transitions were fairly consistent, with externalizing psychopathologies and ever use of marijuana increasing the likelihood of transition at each stage. Peer and parental influences – especially maternal AUD – were linked to initiation and some later stages. Given increasingly permissive attitudes toward marijuana use in the United States, the authors suggest that more research be directed toward understanding the association of AUD development with marijuana use.

Newswise — For the millions of older adults who suffer from osteoarthritis in their lower extremities (hip, knee, ankle or foot), chair yoga is proving to be an effective way to reduce pain and improve quality of life while avoiding pharmacologic treatment or adverse events. A new study, conducted by researchers at Florida Atlantic University and published in the current issue of the Journal of the American Geriatrics Society, is the first randomized controlled trial to examine the effects of chair yoga on pain and physical function in older adults with osteoarthritis. For the study, researchers randomly assigned 131 older adults with osteoarthritis to either the “Sit ‘N’ Fit Chair Yoga©” program developed by Kristine Lee or a health education program. Participants attended 45-minute sessions twice a week for 8 weeks. Researchers measured pain, pain interference (how it affects one’s life), balance, gait speed, fatigue and functional ability, before, during and after the sessions. Results from the study found that participants in the chair yoga group, compared to those in the health education program, showed a greater reduction in pain and pain interference during their sessions, and that reduction in pain interference lasted for about three months after the 8-week chair yoga program was completed. The 8-week chair yoga program also was associated with reductions in fatigue and improvement in gait speed during the study session, but not post session. “With osteoarthritis-associated pain, there is interference in everyday living, limiting functional and social activities as well as diminishing life enjoyment,” said Juyoung Park, Ph.D., co-author and co-principal investigator of the study, Hartford Geriatric Social Work Faculty Scholar and an associate professor in FAU’s College for Design and Social Inquiry. “The effect of pain on everyday living is most directly captured by pain interference, and our findings demonstrate that chair yoga reduced pain interference in everyday activities.” Regular exercise has proven to help relieve osteoarthritis pain, however, the ability to participate in exercise declines with age, and many dropout before they can even receive benefits. Although the Arthritis Foundation recommends yoga to reduce joint pain, improve flexibility and balance, and reduce stress and tension, many older adults cannot participate in standing exercises because of lack of muscle strength, pain and balance as well as the fear of falling due to impaired balance. Chair yoga is practiced sitting in a chair or standing while holding the chair for support, and is well suited to older adults who cannot participate in standing yoga or exercise. “Currently, the only treatment for osteoarthritis, which has no cure, includes lifestyle changes and pharmacologic treatments that are not without adverse events,” said Ruth McCaffrey, D.N.P., A.R.N.P., co-author and emeritus professor in FAU’s College of Nursing. “The long-term goal of this research is to address the non-pharmacologic management of lower extremity osteoarthritis pain and physical function in older adults, and our study provides evidence that chair yoga may be an effective approach for achieving this goal.” The overall goal of this interdisciplinary program is to decrease pain, and improve physical and psychosocial functions of elderly individuals with osteoarthritis who are unable to participate in other exercise and yoga programs. Park and McCaffrey conducted the study with Patricia Liehr, Ph.D., R.N., co-principal investigator, co-author and a professor in FAU’s College of Nursing; David Newman, Ph.D., co-author and an assistant professor in FAU’s College of Nursing; and Joseph G. Ouslander, M.D., co-author, senior associate dean of geriatric programs and chair and professor of the Department of Integrated Medical Science in FAU’s Charles E. Schmidt College of Medicine. “The potential impact of this study on public health is high, as this program provides an approach for keeping community-dwelling elders active even when they cannot participate in traditional exercise that challenges their balance,” said Liehr. Osteoarthritis is the most common form of arthritis in older adults. Consequences associated with osteoarthritis include pain, joint stiffness and functional limitation of activities of daily living. Osteoarthritis is the leading cause of long-term disability among older adults and affects more than 33 percent of people over the age of 65 in the U.S. Annually, osteoarthritis accounts for more than 11 million physician and outpatient visits, 662,000 hospitalizations and an estimated $81 billion in costs for medical and surgical treatments. The World Health Organization estimates that osteoarthritis affects about 10 percent of men and 18 percent of women worldwide. This project is supported by the National Institutes of Health (NIH)/National Center for Complementary and Integrative Health (NCCIH) through grant number 1R15AT007352-01A1.
CAN A WEIGHT LOSS PROGRAM RESULT IN PHYSICAL ACTIVITY IMPROVEMENTS AMONG OLDER ADULTS WITH TYPE 2 DIABETES?
Newswise — Individuals with obesity and type 2 diabetes have lower physical activity (PA) levels than the general population. Given the known health benefits of PA, it is important that lifestyle treatment programs for this population produce significant long-term improvements in PA. This study used a waist-worn tracking device to assess PA levels among 2400 older adults with type 2 diabetes over four years. Participants who were randomly assigned to the lifestyle treatment group were over two times as likely to achieve the study PA goal of at least 175 minutes/week. In addition, they were 1.5 times more likely to maintain this level of PA after four years, compared to those assigned to a basic diabetes education group. Yet, not all participants met the PA goal and some performed very little PA after four years. So, lifestyle programs may need to better address barriers to maintaining PA so that this behavior becomes a life-long habit.
