Designing effective public health messages is challenging, particularly when communicating complex and relatively new health messages such as dementia risk prevention which are still largely unfamiliar to the public. The accessibility of these messages, especially for individuals who speak English as an additional language, remains uncertain in large scale educational interventions. A key strategy to enhance the communication of evidence-based information is to co-design infographics that optimize the accessibility and impact of visual health messages. This paper reports on the co-design process of infographing dementia prevention messages. Qualitative data were analyzed using reflective thematic analysis to generate three themes reflecting the message design preferences of participants: "all hands on deck," "charting the course," and "get on board." This work supports the crucial need to engage the target audience via co-design when creating visual messages as meaningful and accessible educational tools that will resonate with the intended audience. Doing so may help health communicators navigate the creation of visual messages across diverse health domains and populations.

Sea turtle fibropapillomatosis (FP) is a tumor promoting disease that is one of several threats globally to endangered sea turtle populations. The prevalence of FP is highest in green sea turtle ( Chelonia mydas ) populations, and historically has shown considerable temporal growth. FP tumors can significantly affect the ability of turtles to forage for food and avoid predation and can grow to debilitating sizes. In the current study, based in South Texas, we have applied transcriptome sequencing to FP tumors and healthy control tissue to study the gene expression profiles of FP. By identifying differentially expressed turtle genes in FP, and matching these genes to their closest human ortholog we draw on the wealth of human based knowledge, specifically human cancer, to identify new insights into the biology of sea turtle FP. We show that several genes aberrantly expressed in FP tumors have known tumor promoting biology in humans, including CTHRC1 and NLRC5 , and provide support that disruption of the Wnt signaling pathway is a feature of FP. Further, we profiled the expression of current targets of immune checkpoint inhibitors from human oncology in FP tumors and identified potential candidates for future studies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Blackburn, Leandro, Nahvi, Devlin, Leandro, Martinez Escobedo, Peralta, George, Stacy, deMaar, Blangero, Keniry and Curran.)
