Codevelopment of an illustration representative of people living with spina bifida for health educational materials.

BACKGROUND: The lack of health education resources specific to people with disabilities contributes to disparities in outcomes. Developing user-centered materials with representative images tailored to people with disabilities could help improve knowledge and outcomes. OBJECTIVE: As a first step in developing an online sexual health resource for adolescents with physical disabilities, we sought end-user feedback to create illustrated characters for use in educational materials. METHODS: Two styles of characters were developed by the research team, which included a professional disability artist. Verbal and online survey feedback was obtained at the Spina Bifida Association's Clinical Care Conference. A new image was created incorporating initial feedback. The new image and favored image from the first round were then tested through an online survey advertised on the Spina Bifida Association's Instagram story feed. Open-ended comments were organized by categories and overlapping themes. RESULTS: Feedback was obtained from 139 audience members and 25 survey respondents from the conference and 156 Instagram survey respondents. Themes included depiction of disability, nondisability diversity, other physical appearance, emotional response, and design style. Most frequently, participants suggested the inclusion of characters with a range of accurately depicted mobility aids and of characters without mobility aids. Participants also wanted a larger, more diverse group of happy, strong people of all ages. CONCLUSIONS: This work culminated in the codevelopment of an illustration that represents how people impacted by spina bifida view themselves and their community. We anticipate that using these images in educational materials will improve their acceptance and effectiveness.

Antisense oligonucleotides and nucleic acids generate hypersensitive platelets.

INTRODUCTION: Despite the great promise for therapies using antisense oligonucleotides (ASOs), their adverse effects, which include pro-inflammatory effects and thrombocytopenia, have limited their use. Previously, these effects have been linked to the phosphorothioate (PS) backbone necessary to prevent rapid ASO degradation in plasma. The main aim of this study was to assess the impact of the nucleic acid portion of an ASO-type drug on platelets and determine if it may contribute to thrombosis or thrombocytopenia. METHODS: Platelets were isolated from healthy donors and men with advanced prostate cancer. Effects of antisense oligonucleotides (ASO), oligonucleotides, gDNA, and microRNA on platelet activation and aggregation were evaluated. A mouse model of lung thrombosis was used to confirm the effects of PS-modified oligonucleotides in vivo. RESULTS: Platelet exposure to gDNA, miRNA, and oligonucleotides longer than 16-mer at a concentration above 8 mM resulted in the formation of hypersensitive platelets, characterized by an increased sensitivity to low-dose thrombin (0.1 nM) and increase in p-Selectin expression (6-8 fold greater than control; p < 0.001). The observed nucleic acid (NA) effects on platelets were toll-like receptor (TLR) -7 subfamily dependent. Injection of a p-Selectin inhibitor significantly (p = 0.02) reduced the formation of oligonucleotide-associated pulmonary microthrombosis in vivo. CONCLUSION: Our results suggest that platelet exposure to nucleic acids independent of the presence of a PS modification leads to a generation of hypersensitive platelets and requires TLR-7 subfamily receptors. ASO studies conducted in cancer patients may benefit from testing the ASO effects on platelets ex vivo before initiation of patient treatment.
