The research, clinical evaluation, and review efforts of the Departments of Veterans Affairs (VA), Defense (DoD), and Health and Human Services (HHS) related to the health of Persian Gulf veterans are being closely coordinated to avoid duplication, foster cooperation, and to ensure that the most efficient and effective approach is taken to address the various health problems. This report lists joint review activities followed by a list of each agency's primary responsibilities for particular efforts. Each listed activity provides information on current results for that activity. Information on results includes: manuscripts/reports in preparation or submitted for publication; manuscripts/reports accepted for publication in scientifically peer reviewed journals but still in press; manuscripts published in scientifically peer reviewed journals; and U.S. Government reports that have been cleared by the appropriate agency. In cases where there are published manuscripts, the appropriate citations are given and copies of the manuscripts are provided in the Appendix. Results from studies submitted for peer-review but currently unpublished are not provided in order to avoid compromising the scientific peer review process. When U.S. Government reports are listed, the exact citation is provided but copies of these reports are not provided. In the interest of completeness, manuscripts and reports published before 1994 have been included, as well as those published during 1994. Lastly, it should be emphasized that this is a list of activities and is not intended to be construed as a comprehensive research strategy.
