English physician David Barker noticed an interesting phenomenon during the Dutch famine in the mid-1940s. He found that babies from that era — although small for their gestational age — had a much higher incidence of diabetes, heart disease and obesity when they grew up. Barker hypothesized that the health of a pregnant woman could affect whether her child develops chronic diseases. That hypothesis has been confirmed in a number of studies since, and now, WUSM researchers are investigating in mice the link between diabetic mothers and their offspring.

Clubfoot, one of the most common birth defects, affects 1 in 1,000 children.Children can be sensitive to any physical difference they have from other children. But the patients that Christina Gurnett studies are not just worried about having big ears, eyeglasses or braces. Her patients have more emotionally devastating musculoskeletal disorders, including hands with more or less than five fingers, clubfoot and scoliosis. Since the cause of these disorders and others like them is unknown, Gurnett is examining the possible genetic causes of these common disorders, which run in families.

One in eight babies is born prematurely.Nearly one in every eight U.S. babies is born too early — three weeks or more before the estimated due date. Such premature births are the leading cause of newborn deaths and put babies at risk for chronic lung disease and other serious health problems. While some causes of prematurity are known, more than half of women who deliver early have no known risks. In an innovative approach, WUSM researchers Louis Muglia and Justin Fay are searching human DNA for clues to help explain why some women deliver early.

The magnified nanoparticles shown here are actually about 1,000 times smaller than the width of a human hair.Chemistry meets biology in this innovative research program. Using synthetic particles invisible to the naked eye, researchers hope to better diagnose and treat childhood brain cancer, the third most common cancer of children. The particles are called nanostructures or nanoparticles because they are measured in nanometers, an almost unimaginably small unit, a billion times shorter than a yardstick.

Rwandan hero Paul Rusesabagina will speak on his experiences, his ongoing support of Rwanda, the genocide in Darfur, and current issues involving international humanitarian aid, for the final Assembly Series program at 11 a.m.. It is free and open to the public.

WUSM physician Matthew Ellis is conducting research that aims to use the genetic profile of breast tumors to guide breast cancer therapy and ultimately to find new drugs for treating the disease.

Richard Freund, director of the Maurice Greenberg Center for Judaic Studies at the University of Hartford, will discuss “Temple Treasures in the Dead Sea Caves: New Insights from Archaeology” at 11 a.m. April 20 in Room 301, Lab Sciences Building, Danforth Campus.

“Living St. Louis,” a show on KETC (Channel 9) that showcases the colorful culture of our region, will include a segment on Washington University’s Crow observatory tonight at 7 p.m. The segment will also air at 4:30 p.m. on Sunday, April 15, and by Wednesday, April 11, it will be streamed on KETC’s Web site at www.ketc.org.

Smoking while pregnant combined with genetic factors greatly increases the risk of severe ADHD.Past research has suggested that both genes and prenatal insults — such as exposure to alcohol and nicotine — can increase the risk of attention-deficit/hyperactivity disorder (ADHD). But the identified increases in risk have been very modest. Now, a team of Washington University scientists has found that when those factors are studied together, risk of a severe type of ADHD greatly increases.

New HIV therapies have contributed to a decrease in AIDS deaths, but physicians suspected the more potent medications led to symptoms characteristic of metabolic syndrome. However, now researchers at Washington University School of Medicine in St. Louis have found that the rate of metabolic syndrome in HIV-infected patients is virtually identical to that in uninfected people. Furthermore, the type or duration of HIV therapy did not affect the rate of metabolic syndrome.
