The central goal of this proposal is to examine validity and sensitivity of RS-assessed skin carotenoid status as a marker of F\&V intake in a racially and ethnically diverse sample of individuals. First, investigators will examine the association (RS Device Validity) between RS-assessed skin carotenoids and the primary outcomes of objectively-measured plasma carotenoids and self-reported F\&V consumption across four diverse groups: African-American/Black, Asian, White, and Hispanic/Latino (n=213). Then the investigators will conduct a randomized controlled trial to define the relative skin carotenoid responses (RS Device Sensitivity) across racial-ethnic groups, in comparison with plasma carotenoid responses. The investigators will conduct a 6-week randomized controlled trial of a carotenoid-containing juice intervention \[placebo control, low and high dose juice (N=156). Finally, the genetic basis for racial/ethnic group differences in skin carotenoid responses to diet will be investigated through hypothesis-driven genomic analysis of participants from Aims 1 and 2.

This phase II trial studies how well ramucirumab works in treating patients with previously treated biliary cancers that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) or have spread to other places in the body (metastatic) and cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as ramucirumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
