OAK BROOK, Ill. - May 14, 2009 - In a review of more than 2,000 patients coded for Barrett's esophagus, electronic diagnosis overestimated the prevalence of the disease according to researchers in California. They found that only 61.9 percent of patients assigned a billing diagnosis code for Barrett's esophagus actually had Barrett's esophagus after a manual record review.

The large forest fires that sweep through Indonesia in dry periods are not only the result of severe drought. A team of researchers, including Veni grant winner Guido van der Werf, has analyzed the density of smog during forest fires. They have now established that the intensity of the forest fires is directly linked to population density and land use.

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). This model examines the contributions of specific sets of immune cells in fighting influenza A virus.
