Falls can lead to pneumonia, brain injuries, or muscle breakdown. Learn the risks so you can avoid them.

It's easy to see why falls are a top cause of injury and death among older adults. Crashing to the ground with force obviously can break a bone, or worse. But are you familiar with that "worse" part? Learn about fall risks now, so you can do as much as possible to avoid injuries in the future and maintain your mobility and independence.

Fractures

In older adults, about 90% of broken bones (fractures) happen because of a fall. Breaks commonly occur in the ribs, spine, wrist, arm, ankle, or hip.

Ask the doctor

Q. What are mRNA vaccines, and could they prevent other diseases besides infections?

A. The very first vaccines approved in the United States to prevent COVID-19 are a new type: mRNA vaccines. The way any type of vaccine works is to train a person's immune system to recognize and attack a target, like a virus, when it enters the body. A vaccine does that by "showing" the immune system either a harmless (dead or weakened) virus or a critical piece of the virus' protein coat. With the COVID-19 virus, that critical piece is called the spike protein.

Here's what to ask when email and phone calls are the main way to help loved ones in a long-term care facility.

Managing a loved one's care in a nursing home or an assisted living facility has always been challenging. And it's harder now that visitation is extremely limited to protect residents from COVID-19. So how can you check on your loved ones, make sure they're being cared for properly, and let them know you're there for them?

Direct communication

If your loved one is able to communicate well, a daily phone or video call is crucial. But remember that when you ask basic questions — "How are you feeling?" "Are you eating and drinking enough?" "Are you getting enough sleep?" — you may not get an honest answer. "They may just tell you what you want to hear," says Dr. Suzanne Salamon, associate chief of gerontology at Harvard-affiliated Beth Israel Deaconess Medical Center.

How much weight, how many reps and sets, and how often? Here's what new guidelines suggest.

Old-fashioned resistance training — lifting heavy weights multiple times — is the best way for men to slow and even reverse age-related muscle loss, known as sarcopenia. It can also increase your strength, protect against falls, and help you live a more independent life.

Resistance training (also known as strength training) consists of doing upper- and lower-body exercises using free weights (like dumbbells, kettlebells, or barbells), weight machines, resistance bands, or just your own body weight.

Research we're watching

Your surgeon's birthday might be a bad day to get surgery. A study published Dec. 19, 2020, by The BMJ found that among Medicare beneficiaries 65 to 99 years old, those who had one of 17 common surgical procedures on their surgeon's birthday were more likely to die within 30 days of surgery than those who had surgery on other days during the year. To come to this conclusion, researchers looked at all fee-for-service Medicare beneficiaries who underwent emergency procedures from 2011 to 2014. They tracked patient outcomes, making adjustments based on how severe the patient's illness was. Even after factoring in these differences, they still found that patients who underwent surgery on their surgeon's birthday had a higher death rate (6.9%) compared with those who did not (5.6%). The study authors suggested that this might have happened because surgeons were distracted by life events and were not as focused on work.

Exercise and recreational balls can play an important role in recovery and pain reduction.

A golf ball to ease foot pain? A kids' playground ball to recover from a knee injury? The combinations may sound foreign, but they're familiar approaches in the world of physical therapy. Here's how these tools of the trade (and the toy box) can help you.

A playground ball

This is the kind of inexpensive rubber or plastic ball (less than $10) you'll find at a grocery or big-box store. It's about the size of a soccer ball, but lighter. "We commonly use that type of ball for knee rehabilitation. We'll have someone do mini squats against the wall with the ball between the knees. Squeezing the ball strengthens the quadriceps muscles," explains Clare Safran-Norton, clinical supervisor of rehabilitation ­services at Harvard-affiliated Brigham and Women's Hospital.

Here's more incentive to keep your blood pressure under control: a large study published online Dec. 14, 2020, by the journal Hypertension suggests that high blood pressure hastens decline in cognitive abilities (thinking skills). Researchers analyzed two health assessments, taken about four years apart, of more than 7,000 middle-aged and older people in Brazil. The assessments noted changes in a number of cognitive skills, such as memory, language, and concentration. Regardless of age, people with high blood pressure had faster declines in cognitive performance, compared with people who had normal blood pressure. The researchers classified blood pressure as high if the top number was 130 or higher and the bottom number was 80 or higher. But even people with a top number between 120 and 130 experienced faster cognitive decline than people with normal blood pressure. The silver lining: the researchers found that treating high blood pressure at any age appeared to reduce or prevent accelerated cognitive decline. High blood pressure can be controlled with medications as well as pill-free approaches, such as losing weight, exercising, eating a heart-healthy diet, reducing alcohol intake, managing stress, and quitting smoking.

These drugs actually help stop dangerous blood clots from forming. Here's when you may need them.

Nearly everyone has heard of "blood thinners." Maybe you or someone you know takes one. But these drugs don't "thin" blood at all.

"They are actually anti-clotting drugs," says Dr. Gregory Piazza, a cardiologist with Harvard-affiliated Brigham and Women's Hospital. "They prevent potentially dangerous blood clots from developing in people at high risk, like those who have atrial fibrillation or a stent in a blood vessel, or who are immobile after surgery."

Wearable activity or fitness trackers and smartphone apps are helpful for goal setting and measuring how many steps you take or how much time you spend exercising. But do they motivate you to become more active? Probably a little, finds a review of randomized controlled trials published online Dec. 21, 2020, by the British Journal of Sports Medicine. Researchers combed through 28 studies that included a total of more than 7,400 adults (ages 18 to 65) who used fitness trackers or apps for an average of three months. Compared with people who did not use the devices, people who did increased their activity by 1,850 steps per day. Apps and trackers that included prompts and cues to stay active appeared to be most effective. If your smartphone doesn't already have a built-in basic fitness tracker that counts your steps and calories burned, you can find an app that does. Some are free. Fancy tracking devices, with all the bells and whistles, including heart rate monitors and cellphone capability, cost as much as $1,300. But even the simplest ones help remind you to move.
