Extending supervised outpatient rehabilitation by six months helps elderly patients more fully recover from hip fractures, according to the first controlled study of its kind. The study also showed for the first time that these patients, previously thought to be too frail for weight training, can benefit from progressive resistance exercise training.

It wasn’t a fashion show, but more than 120 incoming students donned new attire Aug. 13 during the Washington University in St. Louis School of Medicine’s annual White Coat Ceremony. The ceremony welcomes incoming medical students, and the white coat is symbolic of their transition into the study of medicine and their role as care givers.

A test being developed by WUSM researchers could more definitively tell doctors whether or not a patient has Alzheimer’s disease. Read more about the procedure in this St. Louis Post-Dispatch article written by Kay Quinn.

Blood from umbilical cords can treat a wide range of life-threatening illnesses in children, from leukemia to sickle cell disease. Cynthia L. Price, a WUSM pediatric research coordinator at St. Louis Children’s Hospital, describes the benefits of donating cord blood in the following St. Louis Post-Dispatch article.

A protein linked to increased lifespan in yeast and worms can also delay the degeneration of ailing nerve cell branches, according to WUSTL researchers. Scientists report in the Aug. 13 issue of Science that their findings might open the door to new treatments for a wide range of neurodegenerative disorders, including Parkinson’s, Alzheimer’s and Lou Gehrig’s disease.

ManaryMark Manary, a WUSM pediatrician at St. Louis Children’s Hospital, is saving the lives of children in Malawi with peanut butter. His revolutionary new method for treating starving children in malnourished regions could become a worldwide standard of care. Tina Hesman tells the story of Manary’s work in the following St. Louis Post-Dispatch article.

Neurons communicate at a synapseAs the nervous system develops early in life, it must create millions of synapses—small spaces between nerve cells across which the cells can communicate. Scientists have long speculated that these synapses are deliberately organized to place the structures that send messages on one cell directly across from the structures on another nearby nerve cell that receive those messages. School of Medicine researchers have provided the first experimental proof of this theory at the level of the nervous systems’ most fundamental unit: individual clusters of structures that send and receive signals.

People who are enrolled in Medicare Choice HMO plans with drug coverage die at about the same rate as those in traditional fee-for-service Medicare plans, but mortality rates for those in Medicare HMO plans without drug coverage are substantially higher. That’s the conclusion of a recent study done by Gautam Gowrisankaran, Ph.D., an assistant professor of economics at the Olin School of Business of Washington University in St. Louis, with University of Minnesota colleague Robert J. Town. The researchers’ estimates imply that a 10-percentage point shift in coverage from fee-for-service to HMO plans without drug coverage could result in 51,000 additional deaths per year among the elderly.

An electron micrograph of strep bacteria infecting muscle tissueMicrobiologists at the School of Medicine discovered that Strep A, the bacteria responsible for strep throat and other more serious disorders, has a wasplike “stinger” it uses to infect cells. Scientists had expected to find a random profusion of pumps for spraying infection-related compounds. The newly discovered, dedicated stinger could prove to be an easier target for new infection-preventing drugs.
