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 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.

HarbourJ. William Harbour has been named the Paul A. Cibis Distinguished Professor of Ophthalmology and Visual Sciences. Washington University Chancellor Mark S. Wrighton joined Larry J. Shapiro, executive vice chancellor for medical affairs and dean of the School of Medicine, in announcing the appointment.

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.

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?

Researchers have found that two common organisms collude and collaborate to increase the amount of calories harvested from a class of carbohydrates found in food sweeteners. In the study, conducted in previously germ-free mice, colonization with two prominent human gut microbes led to fatter mice. Scientists at the School of Medicine called the results an illustration of how understanding the menagerie of microorganisms that live in our guts can provide new insights into health.

School of Medicine researchers will study the effects of an antibiotic on asthma symptoms in those whose symptoms are not completely controlled by their medication.
