A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

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.

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.

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.

People who have diverticular disease have tiny pouches (diverticula) in the lining of the colon that can bleed or perforate and develop infection (called diverticulitis). People with diverticular disease should eat a healthy diet rich in fiber, drink lots of water, exercise regularly, maintain a healthy weight, not smoke, avoid straining in the bathroom, and report bleeding or pain to a doctor. However, it's not necessary to avoid eating nuts, seeds, or popcorn, which were once believed to lodge in diverticula and cause problems. That old advice turned out to be wrong.

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.

Millions of people have tinnitus, a condition where a person hears a sound inside the head that does not come from any external source. There are many possible causes and no cure, but there are ways to ease the symptoms, one of which is sound therapy, which uses external sound to alter a person's perception of or reaction to tinnitus.

Rapid COVID tests aren't foolproof, but can provide an added layer of assurance if people take them before a planned gathering, in addition to following other preventive strategies.
