It’s part of the ninth annual Nationwide Asthma Screening Program; the condition is responsible for nearly 4,500 deaths each year.

The urban legends about managed care convey a sense that managed care often leads to early death. However, the business methods employed by managed care frequently result in reduced cost for the companies and the individuals enrolled in the programs. Because of the potential savings, the trend has been to encourage Medicare enrollees to use managed care programs. A recent study by a professor in the business school Washington University in St. Louis and a colleague suggests that it’s not managed care that increases mortality; it’s lack of drug coverage. The study suggests that a one percent increase in the number of people enrolled in Medicare Managed Care without drug coverage would result in an additional 5,100 deaths among the elderly population of the United States in one year.

As our brains mature, we tend to use the red regions more frequently for these certain tasks, using the regions represented in blue less.Children activate different and more regions of their brains than adults when they perform word tasks, according to investigators at Washington University School of Medicine in St. Louis. Reporting in the journal Cerebral Cortex, the researchers say those changes in regional brain activity from childhood to adulthood may reflect the more efficient use of our brains as we mature.

Adolescence can be a trying time for the whole family.Adolescence is characterized by dramatic physical changes as young people grow from childhood to physical maturity. During adolescence, we gain 50 percent of our adult weight and 20 percent of adult height while going through puberty and developing the ability to reproduce. With so many physical and emotional changes occurring at the same time, Washington University adolescent medicine researchers at St. Louis Children’s Hospital say it’s important for parents to be prepared for change. They also must be ready to listen to their children at any time, day or night, and do as much as possible to stay involved in their lives.

Drawing by an autistic childA research team at Washington University School of Medicine in St. Louis has identified regions of DNA that may be related to risk for autism. The researchers are learning how autism is inherited, and to identify genetic factors, they’re studying families and looking for traits that normally aren’t considered autistic but have connections to autism risk. Several studies have demonstrated that autism has a strong genetic component. If one child in a family is autistic, there’s about a 10 percent chance that a sibling also will have autism.

A look at the activity of 24 genes in 52 patients as those genes respond to the chemotherapy drug 5-fluorourancilOncologists aren’t sure exactly why patients with the same cancer often respond very differently to the same treatment, but a growing body of evidence suggests the answer lies somewhere in the genes. Now researchers at Washington University School of Medicine in St. Louis have become the first to profile the activity of whole sets of genes involved in processing chemotherapeutic drugs.

This is *C. elegans*. Its genome was thought to have been completed until a WUSTL computer scientist found otherwise.A computer scientist at Washington University in St. Louis has applied software that he has developed to the genome of a worm and has found 150 genes that were missed by previous genome analysis methods. Moreover, using the software, he and his colleagues have developed predictions for the existence of a whopping 1,119 more genes.

For technicians in the Genome Sequencing Center (GSC) at the School of Medicine, work is going to go a whole lot faster — hundreds of times faster, in fact. Fast enough to sequence the entire genome of a bacterial organism in one day instead of several weeks.

Researchers at the School of Medicine have found that the “old” fat stored in the body’s peripheral tissues — that is, around the belly, thighs or bottom — can’t be burned efficiently unless “new” fat is eaten in the diet or made in the liver.
