Compared to heterosexuals, the disparity between needing and receiving treatment is thought to be even higher for sexual minorities. Yet, few studies have investigated sexual orientation and its relationship to unmet treatment need or the association between sexual orientation and specific reasons for the inability to enter treatment. Understanding these reasons is critical to eradicating barriers to treatment for sexual minorities. Obejctives Using pooled data from the 2015-2018 National Survey of Drug Use and Health and guided by Andersen's behavioral model of health services use, this study examined the relationship between respondents' sexual orientation and their perceptions of reasons for unmet substance use treatment need. Results Findings indicated that sexual minorities had more than double the odds of having unmet need due to access and insurance barriers. Conclusions While further research and larger samples are needed to understand the relationships revealed by this study more fully, it is clear that sexual minorities do not have equitable access to substance use treatment services relative to heterosexuals. Implications and directions for future research are discussed.Chimeric antigen receptors (CARs) are artificial fusion proteins that incorporate antigen-recognition domains and T cell signaling domains. CD30 is a cell surface protein expressed on Hodgkin's lymphoma, some T cell lymphomas, and some B cell lymphomas. CD30 has a restricted expression pattern in normal cells, so CD30 has good potential as a clinical target for CAR T cells. We compared three different anti-CD30 CAR designs incorporating a single-chain variable fragment derived from the 5F11 fully human monoclonal antibody. 5F11-28Z has hinge, transmembrane, and costimulatory domains from CD28 and a CD3ζ T cell
