An ultrasound screening can detect blockage in the carotid arteries, but a government task force is discouraging such screenings due to the very small percentage of the population at risk for such a stroke.
A study of nurses found that those who had both diabetes and depression had a much higher risk of premature death from cardiovascular disease, compared to those who had only one, or neither.
No medications currently available to treat Alzheimer’s disease can halt or prevent cognitive decline, and it is unknown if any will be discovered. The available drugs can alleviate symptoms and help manage behavioral issues.
Research on intermittent explosive disorder suggests that serotonin levels in the brain and activity in the prefrontal cortex may be contributing factors.
There’s new advice on the best way to protect children riding in cars. And it may mean changes in the way many parents use car seats. A group of children’s doctors and U.S. highway safety officials issued the new guidelines. They say that kids should use rear-facing car seats until age 2 instead of age 1. The change is based on evidence. Research shows that 1-year-olds are 5 times less likely to be hurt in a crash if they’re in a rear-facing seat. Bigger kids who outgrow front-facing seats should use a booster seat. They need the booster until they’re 4 feet, 9 inches tall. Boosters can help prevent abdomen and spine injuries. Poorly fitting seatbelts can cause these injuries during crashes. Finally, the guidelines say, every child younger than 13 should ride in the back seat. The American Academy of Pediatrics issued the new advice. It appears in the journal Pediatrics.

Two surgeries for coronary artery disease provide similar relief from chest pain, a study says. The study included 1,800 people. All of them had narrowed arteries. This can cause severe chest pain. It also puts people at risk for heart attack. About half of people in the study had coronary artery bypass graft surgery, or CABG. In this surgery, blood flow is rerouted to avoid narrowed arteries. The other half of people in the study had their affected arteries held open with wire-mesh tubes called stents. The stents released a drug that helps to reduce scarring of the artery walls. Both surgeries helped. About 7 of every 10 people who had the surgeries were free from chest pain a year later. The study was published March 17 in the New England Journal of Medicine.
Whole-body scanning at airports has become more popular over the past few years. Some are concerned that the radiation from these scans can be a health risk. One type of scanner does not expose people to radiation. But the other type does expose people to a small amount. Experts point out that millions of people will undergo whole-body scanning. But there are many other sources of radiation that people are exposed to each day. Experts also recommend that airports choose scanners with millimeter wave technology, which does not expose people to radiation. The articles appear in the April issue of the journal Radiology.
