Abstract

The Center for Environmental Health Sciences (CEHS) Conference entitled "Directions and Needs in Asbestos Research: New Insights" was held at the University of Montana in Missoula on July 28 and 29, 2005. Researchers, physicians, health care workers, and federal agency representatives from around the country met for a cross-disciplinary exploration of many issues related to asbestos research. Topics included community and psychosocial issues in biomedical research, asbestos exposure assessment, assessment and mechanisms of asbestos-related diseases, and new research directions. This meeting report is a summary of the conference presentations, and of the topics identified for future research directions. This conference was a follow-up to one hosted by the CEHS in June 2002, and continued to take advantage of opportunities to work with a unique population in Libby, MT, where significant asbestos exposures have occurred due to the mining of asbestos-contaminated vermiculite. The goals of this conference were to bring together experts from diverse fields to identify progress made since the last conference and to develop new research avenues that would allow us to address the research needs in emerging asbestos-exposed populations. Participants indicated that these objectives were met, and expressed enthusiasm for follow-up conferences, tentatively planned for the summer of 2007, to maintain the dialog that has been established regarding directions and needs in asbestos research. Selected papers from the conference are presented in this issue of Inhalation Toxicology.

In plain English

This article was a conference report, not an original study. The authors summarized a conference titled "Directions and Needs in Asbestos Research: New Insights," held at the University of Montana in Missoula on July 28 and 29, 2005. Approximately 75 people attended and 22 speakers presented. A focus was Libby, Montana, where asbestos exposures occurred over several decades from the mining of amphibole-contaminated vermiculite. Sessions covered community issues in research, exposure assessment, assessment of asbestos-related diseases, disease mechanisms, and new research directions. The report described presentations briefly, without their full data. One talk covered health effects among 11,768 non-New York Fire Department World Trade Center responders, a substantial proportion of whom had new or worsened respiratory symptoms. Another reported autoimmunity in an animal model after exposure to amphibole fibers. At a public forum, the experts generally agreed there was no "safe" level of asbestos exposure. Speakers named the health effects of low-level or short-duration exposures, and the toxicity of the Libby amphibole, as gaps in knowledge. The authors reported that participants felt the conference's objectives were met.

What the study did and found

• Design: conference summary (meeting report) describing presentations at a two-day research conference; no original study data
• Who was studied: Conference of researchers, physicians, health care workers and federal agency representatives, about 75 attendees and 22 speakers, at the University of Montana, Missoula, July 28 and 29, 2005
• Exposure: Asbestos in general, with focus on the Libby amphibole from amphibole-contaminated vermiculite mined at Zonolite Mountain near Libby, Montana
• Main results:
  • A presentation by Dr. Stephen Levin assessed health effects among 11,768 non-New York Fire Department workers and volunteers among World Trade Center responders. A substantial proportion had new-onset or worsened lower and upper respiratory symptoms.
  • Data were presented on amphibole fibers found in the bark of trees near the Libby vermiculite mine site.
  • Speakers identified the health effects of low-level or short-duration exposures, and the toxicity of the Libby amphibole, as gaps in current knowledge.
  • At the public forum, the experts generally agreed that there was no safe level of asbestos exposure.
  • Presentations on mechanisms identified the MAPK, NF-kappaB and AKT/PKB cell signaling pathways as targets.
  • Presentations reported autoimmunity in an animal model after exposure to amphibole fibers. Microarray analysis of lung RNA from asbestos-exposed mice showed specific gene expression signatures for individual fiber types.
  • In a postconference survey, the consensus of participants was that asbestos research had moved forward in the past 3 years. Developing exposure matrices remained a priority.
• The authors' conclusion: The authors concluded that experience from Libby, other vermiculite and asbestos processing sites, and the World Trade Center was providing new insights and tools for future asbestos research. They reported that participants felt both conference objectives (advancing the science and building collaborations) were met.
