The study found that a particular genetic variation helps predict survival in some cases of pulmonary fibrosis, a chronic progressive disease with a median survival of three years. As a result of the study, researchers may want to consider including genetic testing in future clinical trials.
The researchers looked at whether the MUC5B promoter polymorphism, which previously was found to be associated with developing the disease, is also associated with survival time for individuals with pulmonary fibrosis. MUC5B is a protein that is a component of the mucous produced by the bronchial tubes. Pulmonary fibrosis is a condition where lung tissue becomes thickened, stiff and scarred.
The investigators found that genetic changes in the MUC5B gene are associated with marked improvement in survival among patients with pulmonary fibrosis. This represents the first genetic test that can be used to prognosticate in pulmonary fibrosis and may prove useful taking care of patients with this disease. Currently in the United States, there are no drugs approved for use in cases of the disease. This paper indicates that future drug trials should consider including this genetic test to determine the benefit of their intervention.
The research was supported by funding from the National Heart, Lung and Blood Institute and the Dorothy P. and Richard P. Simmons Endowed Chair for Pulmonary Research at the University of Pittsburgh School of Medicine. Twenty-two authors shared credit for the paper, including researchers from the University of Chicago, the University of Illinois at Chicago, the University of Pittsburgh, Vanderbilt University and InterMune from Brisbane, Calif.
Anna L. Peljto, DrPH, from the Colorado School of Public Health was the first author and David A. Schwartz, MD, chairman of the School of Medicine's Department of Medicine, was the senior author of the paper. Additional authors from Colorado institutions were Tasha E. Fingerlin, PhD, from the Colorado School of Public Health; Lori J. Silveira, PhD, Max A. Seibold, PhD, Kevin K. Brown, MD, and Janet L. Talbert, MS, from National Jewish Health; and Elissa Murphy, MS and Marvin I. Schwarz, MD, from the University of Colorado School of Medicine.
David Schwartz this month gave the American Thoracic Society's Amberson Lecture, an honor bestowed annually on an individual with a career of major lifetime contributions to clinical or basic pulmonary research and/or clinical practice. The JAMA study was released online to coincide with its presentation at the American Thoracic Society's international conference.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
