Background: Federally Qualified Health Centers (FQHCs) are an essential place for historically underserved patients to access health care, including screening for colorectal cancer (CRC), one of the leading causes of cancer death in the United States. Novel interventions aimed at increasing CRC screening completion rates at FQHCs are crucial., Objective: This study conducts user testing of a digital patient navigation tool, called eNav, designed to support FQHC patients in preparing for, requesting, and completing CRC screening tests., Methods: We recruited English- and Spanish-speaking patients (N=20) at an FQHC in New York City to user-test the eNav website (2 user tests; n=10 participants per user test). In each user test, participants engaged in a "think aloud" exercise and a qualitative interview to summarize and review their feedback. They also completed a baseline questionnaire gathering data about demographics, technology and internet use, medical history, and health literacy, and completed surveys to assess the website's acceptability and usability. Based on participant feedback from the first user test, we modified the eNav website for a second round of testing. Then, feedback from the second user test was used to modify and finalize the eNav website., Results: Survey results supported the overall usability and acceptability of the website. The average System Usability Scale score for our first user test was 75.25; for the second, it was 75.28. The average Acceptability E-scale score for our first user test was 28.3; for the second, it was 29.2. These scores meet suggested benchmarks for usability and acceptability. During qualitative think-aloud exercises, in both user tests, many participants favorably perceived the website as motivating, interesting, informative, and user-friendly. Respondents also gave suggestions on how to improve the website's content, usability, accessibility, and appeal. We found that some participants did not have the digital devices or internet access needed to interact with the eNav website at home., Conclusions: Based on participant feedback on the eNav website and reported limitations to digital access across both user tests, we made modifications to the content and design of the website. We also designed alternative methods of engagement with eNav to increase the tool's usability, accessibility, and impact for patients with diverse needs, including those with limited access to devices or the internet at home. Next, we will test the eNav intervention in a randomized controlled trial to evaluate the efficacy of the eNav website for improving CRC screening uptake among patients treated at FQHCs., (©Leah C Savage, Luz Estefhany Soto-Cossio, Francesca Minardi, Matthew Beyrouty, Julie Schoonover, Jay Musella, Michaela Frazier, Cristina N Villagra, Jamilia R Sly, Joel Erblich, Steven H Itzkowitz, Lina H Jandorf, Neil S Calman, Ashish Atreja, Sarah J Miller.

Cancer screenings aid in the early detection of cancer and can help reduce cancer-related mortality. The current model of care for cancer screening is often siloed, based on the targeted cancer site. We tested the acceptability of a new model of care, called the One-Stop-Shop Cancer Screening Clinic, that centralizes cancer screenings and offers patients the option to complete all their recommended cancer screenings within one to two visits. We administered surveys to 59 community members and 26 healthcare providers to gather feedback about the One-Stop-Shop model of care. Both community members and providers identified potential benefits (e.g., decreased patient burden, increased completion of cancer screenings) and also potential challenges (e.g., challenges with workflow and timing of care) of the model of care. The results of the study support the acceptability of the model of care. Of the community members surveyed, 89.5% said, if offered, they would be interested in participating in the One-Stop-Shop Cancer Screening Clinic. Future studies are needed to formally evaluate the impact and cost effectiveness of the One-Stop-Shop Cancer Screening Clinic., (© 2024.

We assessed the desorption behavior of pyrene, chrysene, phenanthrene, and tri-alkylated (C3) phenanthrene/anthracenes for non-vegetated and recently vegetated (< 2 yrs) fuel-oiled sediments collected from the Indiana Harbor Canal (IHC), Gary, IN. Bulk sediment and humin were analyzed for PAH concentrations, organic matter composition, and PAH desorption behavior. PAH desorption isotherms and kinetics were determined using batch aqueous extractions and a two compartment, first-order kinetic model Vegetated sediments contained more plant carbon and were more nonpolar and less oxidized than non-vegetated sediments. Desorption kinetics indicated that PAH desorption was primarily controlled by a slow PAH-desorbing fraction (F2) of IHC sediments. However, in vegetated sediments, particularly humin, PAH release from a faster PAH-desorbing fraction (F1) increased as did the rates (k2) of PAH desorption from the dominant slow PAH-desorbing fraction (F2). We propose that vegetation provides aliphatic, nonpolar carbon to IHC sediments that facilitates more rapid PAH desorption from bulk sediment and humin.
