_ Doctors Prescribe Medicines that May Not Be Best for Patients By Jane Farrell article When it comes to choosing which medications to prescribe, patients may have as much influence as physicians, a study has found. Researchers said that that patient requests for specific medications—often spurred by direct-to-consumer (DTC) advertising—have a substantial impact on doctors' prescribing decisions. "A patient request for a specific medication dramatically increases the rate at which physician s prescribe that medication," said lead researcher John B. McKinlay, PhD, of New England Research Institutes, Watertown, Mass.
_ Exercise Muscle Mass May Mean Longer Lifespan By Jane Farrell article Being stronger may equal a longer lifespan, according to new research. The findings, by researchers from UCLA, indicate that the more muscle mass older Americans have, the less likely they are to die prematurely. The study, published in the American Journal of Medicine, was led by Dr. Preethi Srikanthan, an assistant clinical professor in the endocrinology division at the David Geffen School of Medicine at UCLA. It seems to support a growing body of research that muscle mass may be a better predictor of all-cause mortality than the Body Mass Index (BMI).
_ Safer Driving With ΓÇ£Emotion DetectorsΓÇ¥ By Jane Farrell article Technology that identifies the seven universal emotions -- fear, anger, joy, sadness, disgust, surprise, and suspicion – can help make driving safer, according to a study done at Ecole Polytechnique Fédérale de Lausanne.
_ Exercise Exercise and Chronic Disease: Get the Facts By Jane Farrell article From the Mayo Clinic If you have a chronic disease — such as heart disease, diabetes, asthma, or back or joint pain — exercise can have important health benefits. However, it's crucial to talk to your doctor before starting an exercise routine. He or she might have advice on what exercises are safe and any precautions you might need to take while exercising. How can exercise improve a chronic condition? Regular exercise can help you manage symptoms and improve your health. For example:
_ A Better Understanding of Memory Loss By Jane Farrell article Scientists have discovered how a lack of oxygen can interact with inflammation to cause memory loss in conditions like stroke and Alzheimer’s disease. The research, from the University of British Columbia, focused on microglia, part of a newly discovered brain mechanism that contributes to Alzheimer’s. Chronic inflammation and oxygen deficiency are hallmarks of several brain diseases. But until now, there hasn’t been much known about how they contribute to symptoms such as memory loss.
_ When Medicine Does More Harm Than Good By Jane Farrell article About 20 percent of older Americans with chronic conditions are taking medicines that work against each other, according to a new study. In other words, the medication being used to treat one condition can make another condition worse. The problem affects millions of Americans, since three out of four older adults have multiple chronic conditions.

_ Why Food Is Your "Frenemy" By Jane Farrell article By Sherrie Campbell Is food your “frenemy?” Food can be the best friend and comfort you have when you are down or just want to feel something because you are bored. Yet after you eat, you’re consumed with self-loathing. Suddenly, food is the enemy. This is no way to live or to let something outside of you have this much control over how you feel about yourself. It’s not a simple issue, but you can start having a better relationship with food – and yourself – if you understand all the complexities involved:
_ Self-Esteem Helps Avoid Health Problems By Jane Farrell article Having a high level of self-esteem in older adulthood can have a positive effect on physical as well as mental health, new research shows. A study by researchers from Concordia University in Montreal analyzed responses from 147 adults aged 60 and older to measure their self-esteem, stress and symptoms of depression every 24 months over four years. The investigators also measured the levels of cortisol, a hormone that’s released when stress levels are high.
_ Pets Is Your Cat's Medicine Working? By Jane Farrell article There’s a new clinical design to determine whether medicines designed for cats are actually doing the job. In designing the new method, researchers from North Carolina State worked to overcome the “placebo effect” in a pain-management study of cats. Evaluating the effectiveness of a medicine is difficult when it comes to cats, who may not reveal the pain they are suffering and who also are resistant to taking medication.
_ Solving The Lithium Problem By Jane Farrell article A safer form of lithium is on the horizon, researchers say. The drug, one of the most widely used to treat bipolar disorder has a serious drawback of toxicity. But investigators from the University of South Florida discovered that an oral variation, lithium salicylate, maintains steady levels of the drug for up to 48 hours without the toxic “spike” that happens with the rapid absorption of FDA-approved lithium carbonate. Their study results appear in RSC Advances, the journal of the Royal Society of Chemistry.
_ A New Understanding of Metastasis By Jane Farrell article In their deadly journey through the body, cancer cells travel much more efficiently than had been previously thought, a new study shows. Researchers, whose findings were reported in the Proceedings of the National Academy of Sciences, developed a new mathematical formula that they say better reflects the behavior of cells as they travel through 3-D environments.

_ Smart Phone Could Help Doctors to Diagnose Illness By Jane Farrell article Along with all their other functions, smart phones may soon be able to diagnose diseases in real time. Researchers from the University of Houston are developing a diagnostic system that could be read using only a smart phone and a $20 lens attachment. This new device, like essentially all diagnostic tools, relies on spotting specific chemical interactions between something that causes a disease – a virus or bacteria, for example – and a molecule that bonds with that one thing only, like a disease-fighting antibody.
_ Mental & Emotional Health Diagnosing Parkinson's-Related Dementia By Jane Farrell article Researchers have determined that it may now be possible to identify Parkinson's patients who will go on to develop dementia. A study conducted by researchers from the Institut universitaire de gériatrie de Montréal used magnetic resonance imaging in reaching its conclusion. The findings were published in the journal Brain. Parkinson’s is usually associated with problems such as trembling, but patients also have a six times greater risk of developing dementia than do those who don’t have Parkinson’s.
_ Osteoporosis Osteoporosis and Strength Training By Jane Farrell article By Neil Short, Certified Strength and Conditioning Coach Osteoporosis is called the “silent disease” and for good reason. According to the National Osteoporosis Foundation (NOF), more than 50% of women over the age of 50 have it, and few will know until they fall and break a bone. And it doesn’t stop there. The NOF estimates that a full 20% of seniors who break their hip will die within one year from complications due to surgery or recovery, and most end up in nursing homes well before their time.
_ A Blood Test for Alzheimer's By Jane Farrell article There’s an Alzheimer’s blood test now – a procedure that can detect whether a healthy person will develop mild cognitive impairment or Alzheimer’s within three years. The test has a 90 percent accuracy rate. Described in the April issue of Nature Medicine, the test could lead to the development of treatment for early-stage Alzheimer’s, when therapy would be more effective at slowing or preventing onset of symptoms.
_ Aging Well Driving? Better Not Drink -- At All By Jane Farrell article For older drivers, as little as one drink may be too much, according to new research. Investigators from the University of Florida analyzed how drinking legally non-intoxicating levels of alcohol affect the driving skills of people aged 25 to 35 and those aged 55 to 70.
