By mapping the evolution of cancer cells in patients with myelodysplastic syndromes who later died of leukemia, Timothy Graubert, Matthew Walter and their Washington University colleagues have found clues to suggest that targeted cancer drugs should be aimed at mutations that develop early in the disease.

With every meal, immune cells in the intestine stand like sentries at a citadel, turning away harmful bacteria but allowing vitamins and nutrients to pass. Now, researchers at Washington University School of Medicine in St. Louis have identified the cells that chaperone food antigens, or proteins, in the intestine so that the immune system doesn’t mount an attack. Their discovery provides scientists with a potential target for therapies against inflammatory bowel disease, celiac disease and food allergies.

Researchers, including Richard Wilson, PhD, director of The Genome Institute, have identified the first gene mutation associated with a chronic and often fatal form of neuroblastoma that typically strikes adolescents and young adults. The finding provides the first clue about the genetic basis of the long-recognized but poorly understood link between treatment outcome and age at diagnosis.

A program that helps obese patients improve healthy behaviors is associated with modest weight loss and improved blood pressure control in a high-risk, low-income group, according to Graham A. Colditz, MD, DrPH, at Washington University School of Medicine. Compared to those receiving usual care, the lifestyle intervention slowed increases in weight and blood pressure in this population of high-risk patients.

Doctors at Washington University School of Medicine in St. Louis, working with Shriners Hospital for Children and other institutions, have identified a promising new treatment for a rare and sometimes life-threatening bone disorder that can affect infants and young children. Known as hypophosphatasia, the condition upsets bone metabolism, blocking important minerals such as calcium from depositing in the skeleton.

Emergency physician Chris Carpenter, MD, is conducting a study of patients in the emergency room who are older than 65 and at increased risk of having dementia. He wants to determine if referring suspected Alzheimer’s patients to an outreach agency will reduce frequent returns to the emergency department and help them remain independent longer.

Students in the Program in Occupational Therapy talk with Liz Hanson of MarianJoy at the Occupational Therapy/Physical Therapy Job Fair Feb. 23 at the School of Medicine. More than 200 students from Washington University and eight other schools attended the fair, which featured more than 50 representatives from employers in the two fields.

BJC HealthCare, Barnes-Jewish Hospital, St. Louis Children’s Hospital and Washington University School of Medicine are taking another step forward in the future development of the Washington University Medical Center. The vision is to transform the campus over the next 10 years through renovations and new construction.

A new marker of Alzheimer’s disease can predict how rapidly a patient’s memory and other mental abilities will decline after the disorder is diagnosed, Rawan Tarawneh, MD, found while a postdoctoral research associate at Washington University School of Medicine in St. Louis. The new data suggest that VILIP-1 potentially may be a better predictor of Alzheimer’s progression than other markers.

Life-threatening bacterial infections and brain tumors are just some of the serious health issues affecting children. Now, 12 Washington University School of Medicine research teams are preparing to ask – and answer – critical questions about these and other pediatric health problems with help from $3 million in new grants from the Children’s Discovery Institute, led by Mary Dinauer, MD, PhD.
