How stimulants may affect your heart

Stimulant medications, which are usually prescribed to treat attention deficit disorder in children, are being prescribed increasingly to older adults. These drugs may cause a short-term spike in the risk of heart-related problems, including heart attacks, strokes, and arrhythmias. Dietary supplements that promise weight loss or better physical or mental performance may contain prohibited, unlisted, and potentially dangerous stimulants.

Five hours of weekly exercise linked to fewer cancer cases

A study published online Oct. 4, 2021, by the journal Medicine & Science in Sports & Exercise found that about 46,000 U.S. cancer cases per year can be attributed to getting less than 300 minutes of moderate-intensity exercise per week.

Tics and TikTok: Can social media trigger illness?

For hundreds of years there have been documented instances of groups of people developing similar, medically inexplicable, and sometimes bizarre symptoms, such as paralysis, involuntary tics, or uncontrollable laughter. Known as sociogenic illness, a recent example appears to be fueled by social media postings—meaning physical proximity is no longer a factor.

Exercise may heal the heart as well as prevent future problems

Exercise may help to reverse some types of heart damage. Not only can workouts prevent heart problems, but it may help to improve conditions that may raise risk for cardiovascular events. A 2021 study, for example, showed that a yearlong exercise program helped improve heart health in people who were at increased risk for heart failure.

Is there such a thing as a silent stroke?

It is possible to experience a stroke without symptoms. Addressing cardiovascular risk factors can help lower the risk.

Salt substitute associated with lower rates of stroke, death

A large study published online Aug. 29, 2021, by The New England Journal of Medicine found that people who used a salt substitute on their food had a lower risk of stroke, heart attack, and early death, compared with people who used regular salt.

Progress toward over-the-counter hearing aids

In October 2021, the FDA proposed rules to create a new category of over-the-counter hearing aids that would require special regulations and FDA approval. Approval of the rules is expected sometime in 2022.

The heel problem that threatens your mobility

Thick, dead skin patches (calluses) on the heels sometimes become cracked. The condition, known as cracked heels, makes it hard to walk and increases the risk for infection, since cracks open the door for bacteria to enter the body. If infected, cracked heels can turn into foot wounds that become hard to heal, especially in people with diabetes or peripheral artery disease who have poor circulation in their legs and feet.

What is "walking pneumonia"?

Walking pneumonia means a person with pneumonia is highly likely to get well at home and not develop complications. Still, walking pneumonia is considered a significant infection and requires prompt and appropriate treatment. Doctors usually prescribe antibiotics and rest.

Saturated fat and low-carb diets: Still more to learn?

Low-carbohydrate diets have been popular for many years, but due to the high amounts of saturated fat, doctors and nutritionists worry about possible increased risk of cardiovascular disease. A study comparing three diets found that eating a high-fat diet did not necessarily raise heart risk, but the types and quantities of food make a difference.
