The wait is over for an antidote to stop rare uncontrolled bleeding linked to some newer blood thinners. The FDA approved andexanet alfa (AndexXa) on May 3, 2018. It's the first and only antidote to reverse bleeding in people taking apixaban (Eliquis), rivaroxaban (Xarelto), or edoxaban (Savaysa).

Another newer blood thinner — dabigatran (Pradaxa) — already has an approved antidote called idarucizumab (Praxbind). A dose of vitamin K is used to reverse the action of warfarin (Coumadin), a blood thinner used routinely for more than half a century and, until recently, the only such option for most people.

Are you taking a medication that has depression or suicidal thinking as a potential side effect? One or both risks have been linked to use of more than 200 prescription and over-the-counter pills, including medicines that treat high blood pressure, heartburn, pain, and headaches. The more of these drugs you use, the higher the likelihood that you'll experience depression, suggests a study published June 12, 2018, in The Journal of the American Medical Association. Working with five surveys conducted over a nine-year period, researchers evaluated health information from 26,192 adults. About 37% of them reported taking such medications. Of individuals taking three or more of the medications with depression as a possible side effect, about 15% reported depression, compared with about 5% in people not using those medications. Even for people already taking an antidepressant, the addition of one or more of the identified medicines was linked to higher rates of depression. This study was based on surveys, so it didn't prove that the medications caused the reported depression. Nonetheless, if you think you're depressed (and have symptoms such as apathy, hopelessness, changes in sleep or eating habits, and persistent fatigue), ask your doctor if any of the medicines you are taking may be responsible.

Experts recommend one or two servings of fish per week. But healthy vegetarian meals are a good alternative.

Eating fatty fish such as salmon, tuna, or mackerel at least once a week may help prevent heart attacks and other serious cardiovascular problems. That's according to a recent scientific advisory from the American Heart Association, which reaffirms a long-held observation about the health benefits of seafood.

You'll potentially reel in the biggest benefit if you replace less healthy foods — such as red meat or processed meats — with seafood entrees. For example, choose salmon over steak, and swap the ham on your sandwich for tuna.

A salad is a great way to meet your daily vegetable requirement — just toss a few of your favorite veggies together with lettuce or other greens. Most grocery stores sell a variety of salad greens (separate or mixed), prewashed and bagged for convenience. Arugula and watercress are peppery, dandelion and escarole are bitter, mâche and iceberg are sweet, and a green called tatsoi has a mustard flavor. Baby spinach is another popular option.

The USDA recommends two to three cups of vegetables per day for adults. But because greens aren't very dense, it actually takes about two cups of raw greens to make the nutritional equivalent of a one-cup serving of vegetables.

These strategies keep you healthy and safe through your 60s, 70, and 80s.

After age 60, men tend to get thrown together — the so-called 60-and-older group — even though most are quite different in terms of their health.

"While many men are still very fit well into their 60s, 70s, and 80s, others face health challenges and chronic diseases that make daily living difficult," says Dr. Howard LeWine, assistant professor of medicine at Harvard Medical School.

Many people with rheumatoid arthritis (RA) also deal with ongoing depression and anxiety related to their pain and disability. While drugs used to treat the disease help alleviate the joint pain and stiffness, a recent study suggests they may not extend to improving patients' mental health.

The findings, published online June 6, 2018, by Arthritis & Rheumatology, reviewed more than 70 clinical trials and found only a small association between various drugs used for RA, such as adalimumab (Humira), rituximab (Rituxan), abatacept (Orencia), and tocilizumab (Actemra), and mental health outcomes in patients.

If you suffer from low back pain and want to avoid taking strong pain medication, you might want to consult a physical therapist first, suggests a recent study published online May 23, 2018, by Health Services Research.

Researchers reviewed insurance claims for approximately 150,000 adults, ages 18 to 64, who had been newly diagnosed with low back pain. They found that those who first consulted a physical therapist had an 89% lower probability of receiving an opioid prescription compared with those who saw another type of medical provider. They were also less likely to have an MRI or CT scan or to seek out emergency care for their pain.

Pictures may be more effective than words in helping consumers make healthier choices. A new study, published online June 18 by Psychological Science, found that using warning labels that included photos to outline the health risks of sugary drinks appeared to be more effective than written warnings in encouraging people to choose healthier drinks.

Researchers tested two different types of warnings for sugary beverages: warnings with photos and text, and text-only warnings. The warnings were placed near bottled and fountain drinks in a cafeteria at a Massachusetts hospital at different times. During the study period, there were more than 20,000 drinks sold.
