A study of patients who have difficulty paying attention to the left side of their environment has provided some of the first direct evidence that brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury.

Nobel Laureate Kenneth J. Arrow will discuss “The Economics of New Antimalarial Drugs” at 2:30 p.m. Oct. 21 in the Bryan Cave Courtroom, Anheuser-Busch Hall. Arrow, a longtime professor of economics at Stanford University, recently chaired a National Institute of Medicine committee that issued a report titled “Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance.” Malaria, along with tuberculosis and HIV/AIDS, is one of the big three global killers of the world’s poorest people.

Designed to bring together great scientific minds in a comfortable, productive atmosphere, the Farrell Learning and Teaching Center became the new focal point at the School of Medicine in August.

The Department of Obstetrics and Gynecology at the School of Medicine is starting its first federally-funded training program to provide support for postdoctoral fellows in reproductive sciences.

Enlisted to help fight viral infections, immune cells called macrophages consume virus-infected cells to stop the spread of the disease in the body. Now researchers at the School of Medicine have uncovered how macrophages keep from succumbing to the infection themselves.

Physicians from 33 sites in the United States and Canada participated in the Digital Mammographic Imaging Screening Trial.

In vitro fertilization can cost anywhere from $10,000 – $15,000 for each round of treatments. This means access to assisted reproductive technologies (ART) is generally limited to a relatively small portion of couples that seek it. Several state governments have turned to public policy in an attempt to make access to ART more widely available. But two professors from the Olin School of Business at Washington University in St. Louis find that market competition can be as effective at expanding access as requiring insurance companies to cover infertility treatments. At the same time, competition appears to lower the rate of high-risk births and encourages the use of new technologies.

Communities exposed to toxic lead emissions recently won an important victory in federal court through a case filed by the Interdisciplinary Environmental Clinic (IEC) at Washington University in St. Louis. “The court chastised the Environmental Protection Agency (EPA) for long-neglecting its duty to review the lead standard every five years, and placed the agency on a firm schedule for conducting the review,” says Maxine I. Lipeles, IEC director and professor of law and engineering. “Because the lead standard must be revised to protect public health, and the existing standard is out of date, we believe that the EPA is virtually required to revise the standard downward. That would help protect children in communities across the country where smelters and other facilities emit significant amounts of lead into the air. The decision should also caution the EPA to act more promptly in reviewing the other five national ambient air quality standards * for nitrogen oxides, ozone, sulfur dioxide, carbon monoxide, and particulate matter.”
