Cystic fibrosis is a genetic disease that results in progressive multi-organ manifestations with predominance in the respiratory and gastrointestinal systems. The significant morbidity and mortality seen in the CF population has been the driving force urging the CF research community to further advance treatments to slow disease progression and, in turn, prolong life expectancy. Enormous strides in medical advancements have translated to improvement in quality of life, symptom burden, and survival; however, there is still no cure. This review discusses the most current mainstay treatments and anticipated therapeutics in the CF drug development pipeline within the mechanisms of mucociliary clearance, anti-inflammatory and anti-infective therapies, restoration of the cystic fibrosis transmembrane conductance regulator (CFTR) protein (also known as highly effective modulator therapy (HEMT)), and genetic therapies. Ribonucleic acid (RNA) therapy, gene transfer, and gene editing are being explored in the hopes of developing a treatment and potential cure for people with CF, particularly for those not responsive to HEMT.

Background: Bladder cancer survivors and their caregivers face profound practical (eg, use of stoma appliances and care for urinary diversion methods) and psychosocial (eg, depression and anxiety) challenges after surgical treatment with cystectomy. Objective: To improve the health-related quality of life and postsurgical outcomes of both bladder cancer survivors and their caregivers, the team, in collaboration with Sourcetop, Inc (software design) and Dappersmith (graphic design), developed the Cancer Resource and Information Support (CRIS) software. The purpose of this manuscript is to report on the development and usability testing of the CRIS software. Methods: The development of the CRIS software was guided by the Obesity-Related Behavioral Intervention Trials (ORBIT) model for developing behavioral treatments for chronic diseases. The ORBIT model is unique in that it proposes a flexible and progressive process with prespecific clinically significant milestones for forward movement and returns to earlier stages for refinement, and it facilitates communication among diverse groups by using terminology from the drug development model. This paper focuses on 2 phases of the ORBIT model: phase IA: define and IB: refine. During phase IA, the study team developed solutions for the stated clinical problem—adjustment to life post cystectomy—by reviewing the literature and collecting feedback from clinicians, professional organizations, bladder cancer survivors, and their caregivers. During Phase IB, the study team focused on tailoring content in the CRIS software to the user as well as usability testing with 7 participants. Results: The finished product is CRIS, a web-based software for survivors of bladder cancer and their caregivers to serve as a health management and lifestyle resource after surgery. Overarching themes from phase IA (participant feedback) included how to use new medical equipment, tips and tricks for easier living with new medical equipment, questions about health maintenance, and questions about lifestyle modifications. To accommodate our target population, we also incorporated recommendations from the Americans with Disabilities Act for website design, such as large text size, large paragraph spacing, highly contrasting text and background colors, use of headings and labels to describe the purpose of the content, portrait orientation without the need for horizontal scrolling, multiple ways to access a web page within a set of pages, ability to navigate web pages in sequential order, and in-text links that are descriptive. Usability participants evaluated CRIS very positively, indicating that it was easy to use, the functions were well-integrated, and if available, they would use CRIS frequently. Conclusions: CRIS, developed over the course of 18 months by integrating feedback from experts, literature reviews, and usability testing, is the first web-based software developed for bladder cancer survivors and their caregivers to help them adjust to life following cystectomy. The efficacy of CRIS in improving patients’ and caregivers’ quality of life is currently being evaluated in a randomized controlled trial.

Journal of Medical Internet Research - International Scientific Journal for Medical Research, Information and Communication on the Internet #Preprint #PeerReviewMe: Warning: This is a unreviewed preprint. Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn. Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period. Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author). Background: Elicitation of patients’ preferences is an integral part of shared decision making, the recommended approach for prostate cancer decision making. However, existing decision aids for this population do not specifically focus on patients’ preferences. Healium is a brief interactive web-based decision aid that aims to elicit patient’s treatment preferences and is designed for a low health literate population. Objective: This study used a randomized controlled trial to evaluate whether Healium (designed to target preference elicitation) is as efficacious as Healing Choices (a comprehensive education and decision tool) in improving outcomes for decision-making and emotional quality of life. Methods: Patients diagnosed with localized prostate cancer who had not yet made a treatment decision were randomly assigned to the brief Healium intervention or Healing Choices, an extensive decision aid previously developed by our group that serves as a virtual information center on prostate cancer diagnosis and treatment. Assessments were completed at baseline, 6-weeks and 3-months post-baseline, and included decisional outcomes (decisional conflict, satisfaction with decision, preparation for decision-making), and emotional quality of life (anxiety/tension and depression), along with demographics, comorbidities, and health literacy. Results: N = 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (96%), White (76%), married (78.4%), and had an average age of 62.4 years old (SD = 6.9). Within both arms, there was a significant decrease in decisional conflict from baseline to 6-weeks post baseline (Healium, P = <.001; Healing Choices, P = <.001), and a significant increase in satisfaction with one’s decision from 6 weeks to 3 months (Healium, P = .04; Healing Choices, P = .01). Within both arms, anxiety/tension (Healium, P = .23; Healing Choices, P = .27) and depression (Healium, P = .001; Healing Choices, P = <.001) decreased from baseline to 6-weeks, but only in the case of depression was the decrease statistically significant. Conclusions: Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity and the potential for integration into the physician consultation and electronic medical record.

RESULTS A total of 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (272/282, 96%), White (239/314, 76%), married (251/320, 78.4%), and was on average 62.4 (SD 6.9) years old. Within both arms, there was a significant decrease in decisional conflict from baseline to 6 weeks postbaseline (Healium, P≤.001; Healing Choices, P≤.001), and a significant increase in satisfaction with one’s decision from 6 weeks to 3 months (Healium, P=.04; Healing Choices, P=.01). Within both arms, anxiety/tension (Healium, P=.23; Healing Choices, P=.27) and depression (Healium, P=.001; Healing Choices, P≤.001) decreased from baseline to 6 weeks, but only in the case of depression was the decrease statistically significant. CONCLUSIONS Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity, making it the ideal tool for integration into the physician consultation and electronic medical record.
