Millions of people around the world have sickle cell disease, a genetic condition that can cause pain and damage to organs or tissues, and can make children more susceptible to other health problems. In the US, most cases are diagnosed through screening in newborns. Getting connected to the proper care early in a child's life can help prevent complications from the disease.

Every day, more and more adults are getting vaccinated against COVID-19, helping us build toward herd immunity. But what about children and teens? What is the status of research on the vaccines in these groups, and when might vaccines be available for them?

Although it has been known for some time that individuals with dementia frequently have poor, fragmented sleep, two new studies suggest that if you don't get enough sleep in midlife, you are at increased risk for dementia later in life.

A history of discrimination in multiple settings, including health care, may make some people who identify as LGBTQ+ hesitant to get a COVID-19 vaccine, even though the virus has disproportionately harmed this community. If you're struggling to make a decision, this may help you consider benefits and risks.

Childhood trauma may raise the risk of cardiovascular disease, but making lifestyle changes can help you stay healthy.

Traumatic childhood experiences may have a lasting effect on your heart health.

A review published online Dec. 2, 2020, by JAMA Cardiology found that adults who had multiple adverse childhood experiences (ACEs) — like being neglected; suffering physical, sexual, or emotional abuse; or witnessing violence at home — had double the risk of cardiovascular disease and an early death compared with people who didn't face any ACEs at all.

In rare cases, people who have had cosmetic dermal fillers experience swelling after receiving the COVID-19 vaccine, but this shouldn't stop people with fillers from being vaccinated.

New experiences stimulate pathways that improve memory.

Our brains have the capacity to improve as we age. "The mechanisms in place may slow over time, but the brain's ability to change doesn't wane," says Dr. Alvaro Pascual-Leone, medical director of the Deanna and Sidney Wolk Center for Memory Health at Harvard-affiliated Hebrew SeniorLife.

Just as when you work to strengthen aging muscles, though, you need to put in extra effort to keep the "muscle" inside your head in top condition. Among the best ways to do this is to learn new things that continuously challenge your mind.

A little afternoon snooze can help you feel more rested — and it might do you good in other ways, too. A small study from China published online Jan. 25, 2021, by General Psychiatry suggests that afternoon naps (between five minutes and two hours long) may be good for your memory and thinking skills. Researchers put more than 2,200 older adults through a series of health screenings that included blood tests and cognitive assessments, and also asked participants whether and how often they napped. About 1,500 of the participants were nappers. Compared with people who didn't nap, the nappers performed better on cognitive tests, scoring better on location awareness, verbal fluency, and memory. The study was observational, so it can't prove that napping caused the better cognitive test results. Previous studies have shown that afternoon nap benefits decline as age and nap duration increase. Short, frequent naps (less than 30 minutes, four times per week) have been associated with reduced risks for developing Alzheimer's disease. In contrast, people who take long naps (two hours or longer) appear to have worse cognitive function, although it is unclear what is cause and what is effect.
