Sponsor's own description

Background: \- The Agricultural Health Study (AHS) is looking at the long-term health effects of farming exposures including pesticides, crops, and animals. The chronic health effects of exposure to pesticides are easier to study in farmers and their spouses. They know what chemicals they use and tend to live in the same place for most of their adult lives. AHS participants are expected to report any changes in their health. This includes any new medical conditions. Researchers want to follow up on these reports to confirm their accuracy. Objectives: \- To follow up AHS participants who have self-reported that they have a new disease and confirm their diagnosis. Eligibility: \- Current AHS participants. Design: * Researchers will confirm self-reported changes in medical conditions by contacting the AHS participant to ask for more information. * The AHS participant will give permission for researchers to contact their doctor to look at their medical records. They will also be asked to provide a cheek swab or saliva sample. * Diseases of interest are rheumatoid arthritis, lupus, and Sjogren s Syndrome. Other diseases will be followed up in the future. Other diseases will be followed up in the future....
