He was one of the first African-American physicians to join the School of Medicine and was a renowned health-care policy innovator.

The former clinical instructor in the School of Dentistry died of leukemia Feb. 20.

Mammograms could more frequently bear good news if researchers develop an effective breast cancer vaccine.Progress toward development of a breast cancer vaccine has been reported by researchers at Washington University School of Medicine and the Siteman Cancer Center in St. Louis. Physicians believe a vaccine-induced immune response could be used to supplement other cancer therapies or to immunize high-risk people against cancer.

WUSM researchers have developed new risk estimates for premature babies.If a woman goes into labor before her baby is full term, her obstetrician must make a crucial recommendation: delay labor or allow it to continue. Delivering the baby prematurely may increase the risk of neonatal respiratory distress syndrome (RDS), a potentially fatal condition. Now medical researchers at Washington University in St. Louis have generated new risk estimates for RDS that allow physicians to make delivery decisions with far greater confidence.

Dr. Mario Castro and nurse Michelle Jenkerson visit with patient Wil Klages and his mom, Peg Klages.Studying Respiratory Syncytial Virus (RSV) to learn what puts children at risk for the most severe infections, Washington University researchers at St. Louis Children’s Hospital found that a child’s age at the time of infection and whether that child lives with a smoker could mean the difference between the sniffles and the intensive care unit.

Most pediatric burns can be prevented.Childhood burns can happen when least expected: An inquisitive toddler crawling around the kitchen pulls on a coffee pot’s dangling electrical cord, causing the scalding liquid to burn his tiny arm. The Trauma and Burn Program at Washington University School of Medicine and St. Louis Children’s Hospital admits approximately 165 burn patients a year and treats another 200 on an outpatient basis. Robert P. Foglia, M.D., director of the program, offers tips on how to prevent household burns, the leading cause of accidental deaths in the home.

Michael R. Brent and Tamara L. Doering examine data from the *C. neoformans* microarray.A team of collaborators, including two researchers from Washington University in St. Louis, has sequenced the genomes of two strains of the fungus Cryptococcus neoformans (C. neoformans), one which is virulent, the other harmless. This work provides researchers with clues on how the fungus does its dirty work and a host of genes to study for a better understanding of fungal pathogens in general. Estimates are that about 15 percent of people with HIV will suffer at least one life-threatening infection of C. neoformans. In Africa, that could be as much as 40 percent of HIV sufferers.

Rates of celiac disease are significantly higher in patients with osteoporosis, according to researchers at the School of Medicine. They recommend using blood tests to screen osteoporosis patients for celiac disease because their study has shown that treating celiac disease with diet can restore bone health in these patients.
