An experimental nasal spray shows promise for quickly treating an abnormally fast heart rhythm known as supraventricular tachycardia (SVT), a new study reports.

Caused by an electrical misfire that overrides the heart's natural pacemaker, SVT occurs unpredictably, lasting anywhere from minutes to hours. Although usually harmless, the condition can make people dizzy or lightheaded. People with persistent SVT usually need to go to an emergency room for an injection of a drug to slow the heart.

There is a lot of technology that tracks your health, from counting steps to counting burned calories. One of the most valuable fitness tools though is a heart rate monitor, which tells you how many beats your heart takes per minute.

"Whether you're just getting started with an exercise routine or are a committed fitness enthusiast, tracking your heart rate can help you maintain the necessary moderate level of intensity for optimal benefits without worrying about doing too much or too little," says Dr. Aaron L. Baggish, associate director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital.

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.

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.

Q. A friend of mine recommended I try whole-body cryotherapy for arthritis pain. Is this technology proven to work?

A. Whole-body cryotherapy is a technology designed to cool the body by exposing it to subzero temperatures (typically –200° to –300° F) for short sessions of two to four minutes. In some cases, people sit in a cold room; in others, they are placed in a special enclosure that cools them from the neck down. The theory behind cryotherapy is that cold temperatures can reduce inflammation and swelling in the body — much like an ice pack would on your swollen ankle. People who promote cryotherapy claim it can help treat symptoms related to numerous conditions, including arthritis, asthma, depression, and chronic pain, among others. They also claim that whole-body cryotherapy can aid in weight loss, soothe sore muscles, boost metabolism, and even get your blood circulating more efficiently. But while that may sound great, there's really no scientific proof that whole-body cryotherapy is safe, or any evidence to support claims about its health benefits, according to the FDA. And the FDA has not cleared or approved any whole-body cryotherapy device to treat any medical condition. In short, whole-body cryotherapy is still unproven and could potentially bring risks, so if you are considering using the technology, it's a good idea to discuss the decision with your doctor first.

Wondering if that herb or herbal supplement is safe and effective? A new app can tell you. The National Center for Complementary and Integrative Health has introduced a new app called HerbList, which provides research-based information on various herbal products.

The app, which is available free on the Apple App store and Google Play store, is designed to give consumers important details on the safety and effectiveness of some of the most popular herbs and herbal supplements. While marketers may claim these products bring health benefits and are safe, that might not always be the case. This app can help you sort through the claims to determine what's real — and what's not.
