Researchers tested the spoken language skills of children who had cochlear implants and found that with increased implant time, children’s vocabulary was richer, their sentences longer and more complex and their use of irregular words more frequent.

Science is now poised to answer an important and longstanding question about the origins of Alzheimer’s disease: Do Alzheimer’s patients have high levels of a brain protein because they make too much of it or because they can’t clear it from their brains quickly enough?

An epilepsy drug that has been on the market for decades can ease the symptoms of adult sufferers with a genetic disorder that seriously weakens muscles. Scientists at the School of Medicine retrospectively reviewed results from off-label use of the drug valproate to treat seven adult spinal muscular atrophy (SMA) patients.

An education and retraining program that previously reduced catheter-associated infections in ICUs at Barnes-Jewish Hospital and Missouri Baptist Medical Center has been successfully exported to five other medical centers across the nation, clinicians report in the July issue of Infection Control and Hospital Epidemiology.

July is UV Safety Month and prolonged exposure to the sun’s ultraviolet rays without protection may cause eye conditions that can lead to vision loss, such as cataracts and age-related macular degeneration. Sunglasses and wide-brimmed hats are your best protection against UV-related vision problems, but be careful when you’re shopping for sunglasses — the wrong kind of lenses might do more harm than good.

WUSM researchers believe a vitamin vitamin natually found in carrots and tomatoes can protect skin from sunburns. The vitamin. zeaxanthin, is a natural pigment found in fruits and vegetables.

The newest concept for treating coronary artery disease is to induce hearts to grow their own new blood vessels to bypass damaged tissue or clogged arteries. Unfortunately, clinical trials of two important blood-vessel growth factors have not produced stellar results. Now researchers at the School of Medicine have investigated a third signaling molecule that could overcome problems associated with the previous two.

The answer to a 50-year-old question has been found by scientists at the School of Medicine. The question: Is it possible to accurately measure the intrinsic filling function of the heart?
