Research we're watching

Although hormone therapy was once thought to help preserve cognitive function after menopause, there is mounting evidence to the contrary, including a recent report from the Kuopio Osteoporosis Risk Factor and Prevention Study.

Researchers in that project sent questionnaires to all women ages 47 to 56 who lived in the Finnish province of Kuopio in 1987. The women completed questionnaires every five years, providing information about their lifestyles, medication use, and illnesses. The researchers checked the information in the questionnaires against prescription registries and medical records up to 2009.

Q. My uncle was told he had fluid around his heart. What does that mean, and how is it treated?

A. The heart is surrounded by a thin, two-layer sac called the pericardium. It protects the heart, limits its motion, and prevents it from expanding too much when blood volume increases. Normally, there isn't any fluid between the pericardium and the heart muscle. But there are many reasons fluid can accumulate in this space, including an infection, a heart attack, surgery, cancer, kidney failure, and a host of other conditions.

Low-dose aspirin therapy is standard treatment for people who have suffered a heart attack or stroke to protect them from a second one. But what about people who don't have cardiovascular disease, but do have specific risk factors, such as type 2 diabetes? A study published in the Feb. 14, 2017, Circulation found that low-dose aspirin therapy in fact did not lower this group's risk for heart attack or stroke.

The researchers recruited more than 2,500 people, ages 30 to 85, with type 2 diabetes and randomly assigned them to take either 81 mg or 100 mg of aspirin daily, or no aspirin, for three years. At the 10-year follow-up, they found that the aspirin therapy did not lower risk of either heart attack or stroke compared with taking no aspirin at all. The reason is not clear, but the researchers speculated that people with diabetes might not experience the expected anti-clotting action of aspirin.

Here's how to get a better deal on your medication.

You're not alone if you've ever skipped filling a prescription because it was expensive. Cost is one barrier to keeping people on their medication regimens. "It's a real problem. Medications only work if people take them, and you can't take them if you can't afford them," says Dr. Joshua Gagne, a pharmacist and epidemiologist with Harvard-affiliated Brigham and Women's Hospital.

According to a National Center for Health Statistics survey, about 8% of adults in the United States don't take prescribed medications because they can't afford them.

Q. I've been taking the blood thinner warfarin (Coumadin) for a few years. I know there are new kinds of blood thinners, but I've heard they have downsides. Should I stick with warfarin?

A. Here's what you need to know. Some medical conditions lead to blood clots. The most common one is the irregular heart rhythm called atrial fibrillation. About 20% of all strokes are caused by clots that result from atrial fibrillation 鈥� usually because of inadequate treatment with blood thinners.

Dietary supplements made from red yeast rice contain substances called monacolins, which are similar to the active ingredient in cholesterol-lowering statin drugs. And like statins, red yeast rice products may cause rare but serious side effects, such as muscle injury and liver damage, as noted in a study published online January 19, 2017, by the British Journal of Pharmacology.

The study, based on a review of 13 years of patient data by Italian researchers, notes that people who can't tolerate statins often take red yeast rice supplements. But there are no studies testing the safety of red yeast rice compared with statins. In the United States, the FDA considers red yeast rice products that contain more than trace amounts of monacolins to be unapproved new drugs and therefore illegal to sell. Yet dozens of these unregulated products remain on the market.

Almost one-third of older adults take statins to help lower cholesterol levels, but new guidelines and research have restarted the conversation on the role statins play in your health.

Since they were introduced two decades ago, statins have been touted as a driving force in helping many older men reduce their risk of heart attack and stroke.

New research even suggests these drugs might treat other conditions, like Alzheimer's disease, and lower your risk of death from cancer (see "Other statin uses?").

Q. I've heard that bioidentical hormone pellets injected near the hip are more effective than bone-building drugs in stopping bone loss and preventing hip fracture. Is this true?

A. The FDA hasn't approved hormone pellets for preventing or treating bone loss. Moreover, there are no randomized controlled trials on record, so we don't know whether hormone pellets are more effective 鈥� or even as effective 鈥� as the FDA-approved medical therapies. Finally, there aren't any published reports explaining how the hormones are metabolized in the body or the side effects they may have.

Some doctors are more likely to prescribe opioids to their patients, and those patients are more likely to end up taking them long-term. It's crucial for consumers to educate themselves about the risks of taking opiates, and to consider alternatives if possible.

Author and migraine sufferer Joan Didion once wrote, "That no one dies of migraine seems, to someone deep into an attack, an ambiguous blessing." At that time, migraines weren't something that could be prevented. Today, that's a possibility for some people who have severe migraines, frequent migraines (more than three or four times a month), or migraines that don't respond well to treatment.

The cornerstone of migraine prevention is managing triggers like stress or certain foods or strong perfumes. Alternative and complementary therapies (like acupuncture) help some migraine sufferers keep headaches at bay.
