Yoga is good for the muscles and the mind. New research suggests that it may also be good for the heart. A review of yoga and cardiovascular disease published in the European Journal of Preventive Cardiology indicates that yoga may help lower heart disease risk as much as conventional exercise, such as brisk walking. It can help people lose weight, lower blood pressure and cholesterol, and ease stress. Each of those changes works to prevent heart disease, and can help people who already have cardiovascular problems.
One type of lower back pain, called lumbar spinal stenosis, can be painful and potentially disabling. An operation known as laminectomy or decompression is sometimes done to ease the pain of lumbar spinal stenosis. Physical therapy can also help. Researchers compared the results of laminectomy to those of a special physical therapy program among nearly 170 Pittsburgh-area men and women with lumbar spinal stenosis. The two approaches worked equally well — pain declined and physical function improved. There were more complications in the surgery group. Since there are no hard and fast rules for choosing the right treatment for lumbar spinal stenosis, the results of this study offer some guidance — try a well-designed physical therapy program first.
The tragic story of copilot Andreas Lubitz, the man who apparently crashed Germanwings flight 9525 into the Alps in an act of suicide and murder, demonstrates the opaqueness of mental illness. It is difficult to know when a person is struggling with private psychological and emotional pain that might lead to dangerous or destructive behavior. All of us tend to keep our thoughts, especially our most disturbing ones, to ourselves. Even when encouraged to speak those thoughts aloud — to a mental health professional, for example — it is very difficult to do so. This tragedy will likely spark calls for increased scrutiny of pilots. That’s not necessarily a bad thing, but it could lead to the unintended and undesirable consequence that pilots will become even more wary of seeking help. To honor the lives lost will require policies that protect the public while not being punitive to pilots.
This week’s inaugural April Fool’s Day edition of JAMA Internal Medicine carried a report entitled “Association Between Apple Consumption and Physician Visits: Appealing the Conventional Wisdom That an Apple a Day Keeps the Doctor Away.” Based on actual national nutrition data collected from nearly 8,400 men and women it concludes, “Evidence does not support that an apple a day keeps the doctor away; however, the small fraction of US adults who eat an apple a day do appear to use fewer prescription medications.” Apples may have failed this critical scientific test, but they are still an excellent choice as a snack, pick-me-up, or dessert.
Hospitals across America are merging. In 2014 alone, there were 95 mergers, acquisitions, and joint ventures among U.S. hospitals, down only slightly from 98 in 2013. What is fueling this trend toward hospital consolidation — and why should you, as a consumer of health care, be concerned about it? Hospital administrators who create the mergers believe that hospital consolidation improves efficiency, access to care, and quality of care, and may lower costs. In contrast to hospital administrators, many health economists are wary about the growing number of these mergers. When individual hospitals merge into larger systems, they gain a larger share of the consumer health market. That puts them in a position to ask health insurance companies to pay more for medical care and procedures. These higher prices are not borne by the insurers, but by consumers in the form of greater premiums. Thus, some economists argue, mergers drive up health care costs and place added financial pressure on consumers.
President Obama’s announcement of a Precision Medicine Initiative was one of the few items in this year’s State of the Union address to garner bipartisan support. And for good reason. Precision medicine, also known as personalized medicine, offers the promise of health care based on your unique DNA profile and the profiles of a million other individuals. Getting to precision care will require new diagnostic tests. It will also need a new regulatory framework to make sure that technologies aren’t launched before they’ve been proven to be safe and effective, according to a Perspective article in The New England Journal of Medicine. It may take a few years to design this new vetting system and put it in place. In other words, precision medicine is on the horizon, but it isn’t around the corner.
Is brain damage an inevitable consequence of American football, an avoidable risk of it, or neither? An editorial published yesterday in the medical journal BMJ poses those provocative questions. Chad Asplund, director of sports medicine at Georgia Regents University, and Thomas Best, professor and chair of sports medicine at Ohio State University, offer an overview of the unresolved connection between playing football and chronic traumatic encephalopathy, a type of gradually worsening brain damage caused by repeated mild brain injuries or concussions. The big question is whether playing football causes chronic traumatic encephalopathy or whether some people who play football already at higher risk for developing it. The Football Players Health Study at Harvard University hopes to provide a solid answer to that and other health issues that affect professional football players.
Older adults with new back pain usually end up getting a CT scan or MRI. That’s often a waste of time and money and has little or no effect on the outcome, according to a new study from the University of Washington. The results of the study contradict current guidelines from the American College of Radiology. The guidelines say that it’s “appropriate” for doctors to order early MRIs for people ages 70 and older with new-onset back pain, and many doctors do just that. The study, which followed more than 5,200 men and women over the age of 65 who saw a primary care physician for a new bout of back pain, found that people who got early back scans did no better than those who didn’t have scans. The scans added about $1,400 per person to the overall cost of back pain care — with no measurable benefit.
If you or a loved one is age 65 or older, getting vaccinated against pneumonia is a good idea — so good that the Centers for Disease Control (CDC) now recommends that everyone in this age group get vaccinated against pneumonia twice. For the past 30 years or so, the CDC has recommended that everyone ages 65 and older get a single-dose pneumonia vaccine called pneumococcal polysaccharide vaccine 23 (PPSV23). This vaccine is also recommended for those between the ages of two and 64 who are at high risk of getting pneumonia. Findings from a large clinical trial called CAPiTA, published today in The New England Journal of Medicine, show that a second vaccine, called pneumococcal conjugate vaccine 13 (PCV13), provides further protection against pneumonia and related infections. When it comes to preventing pneumonia, the bottom line for older individuals is clear: Get vaccinated twice.
If you’re among the one in three American adults with high blood pressure, be sure you’re getting plenty of the B vitamin known as folate. Doing so may lower your odds of having a stroke, an often disabling or deadly event linked to high blood pressure. That’s the conclusion of a large trial conducted in China, where many people don’t get enough folate. Most Americans get plenty of folate or its synthetic version, folic acid. That’s largely because grain folic acid is added to most grain products, including wheat flour, cornmeal, pasta, and rice. It’s a good idea for everyone to do a diet check to make sure it delivers enough folate. Good sources include green leafy vegetables, beans, and citrus fruits.
