Heavy drinking is associated with a number of problems, but one surprisingly common problem involves not remembering large chunks of time. Called alcohol-induced blackouts, these memory losses were reported by more than 39 percent of women and more than 50 percent of men studied by researchers from Washington University School of Medicine in St. Louis and the Queensland Institute on Medical Research in Australia. The researchers also found that genetic factors play a big role in whether or not a person blacks out after heavy drinking. Studying more than 2,300 pairs of Australian twins, the research team was able to determine that more than 50 percent of the risk of blacking out seems to be controlled by genetic factors, and the role of genes is even greater in people who report blacking out multiple times.

With the graying of America, millions of people across the nation are facing the same tough question: when do older people become unsafe drivers? In one of the first studies to track driving performance in older adults, researchers at Washington University in St. Louis found that over time, driving abilities predictably worsen in individuals with early Alzheimer’s disease and, to a lesser extent, in older adults without dementia. People with mild dementia had the fastest rate of decline, but there also were declines in nondemented study participants. The researchers also found that increased age alone appeared to be a risk factor in driving performance. Because Alzheimer’s disease is progressive and driving performance inevitably does worsen, the challenge is to figure out how to predict and evaluate dangerous declines in driving performance. The researchers suggest that testing individuals with mild dementia every six months might be a useful way to keep unsafe drivers off the roads.

Faddis and colleagues use a catheter with a magnet at its tip combined with a magnetic guidance system machine to help guide the magnetic catheter as it moves inside the heart.Thanks to advances in cardiology and in magnetic technology, it’s now possible to use magnetic fields to guide tools used to treat certain heart rhythm problems. Cardiologists can treat heart rhythm abnormalities without surgery by using catheters to deliver treatment. Catheters are long, narrow tubes that are run from the groin to the heart via blood vessels using X-ray images for guidance. A team at Washington University School of Medicine in St. Louis has found that the Magnetic Navigation System (MNS) developed by Stereotaxis Inc. allows them to guide catheters within the heart more accurately. Instead of a standard design, MNS catheters contain a magnetic tip. In the same way the needle on a compass aligns itself with the direction of the Earth’s magnetic field, the catheter’s magnetic tip aligns itself with a magnetic field surrounding the patient and allows physicians to more easily guide the catheter in order to locate and treat problem areas in the heart.
