Enhancing Mission Wellness: Iterative Optimization and Stakeholder Engagement to Promote Sexual and Reproductive Health in the United States Military.

Sexual and reproductive health is critical for the readiness of the warfighter, as costs of sexually transmitted infections and unintended pregnancy result in added health care costs, lost mission time, and impact on morale. The Multiphase Optimization Strategy (MOST) is an engineering-inspired framework used to optimize biobehavioral interventions. The Military Active-Duty Reproductive and Sexual Health (MARSH) research team applied the MOST framework to develop "Mission Wellness"-an electronic health intervention to promote sexual and reproductive health within the U.S. Military. From 2017 to 2022, the MARSH team implemented the first and second phases of MOST to develop and optimize "Mission Wellness." All phases received institutional review board approval. The first phase consisted of expert and literature review, qualitative interviews, and beta testing to identify intervention components and the optimization objective and to inform study design. The second phase consisted of a factorial trial. Figures1-4 outline the research program approach, demographics of the sample, and format of the app. Service members who used the application found it to be acceptable and, overall, reported that it would be easier to talk to a sexual partner about risk behaviors and history at the post-intervention assessment compared to baseline. This iterative optimization approach using both local and strategic engagement enhanced program development and set the stage for dissemination and implementation efforts. In line with the iterative nature of MOST, the lessons learned during the optimization trial led the MARSH team to return "Mission Wellness" to the preparation phase. The utilization of mixed (i.e., qualitative and quantitative) research methods and engagement with stakeholders at multiple levels of the military enterprise provided the information necessary to further optimize "Mission Wellness." This programmatic approach also provides a blueprint for the development of research design and testing in military health care balancing rigor and agility.

Co-Designing a Smoking Cessation Chatbot: Focus Group Study of End Users and Smoking Cessation Professionals.

Our prototype smoking cessation chatbot, Quin, provides evidence-based, personalized support delivered via a smartphone app to help people quit smoking. We developed Quin using a multiphase program of co-design research, part of which included focus group evaluation of Quin among stakeholders prior to clinical testing. This study aimed to gather and compare feedback on the user experience of the Quin prototype from end users and smoking cessation professionals (SCPs) via a beta testing process to inform ongoing chatbot iterations and refinements. Following active and passive recruitment, we conducted web-based focus groups with SCPs and end users from Queensland, Australia. Participants tested the app for 1-2 weeks prior to focus group discussion and could also log conversation feedback within the app. Focus groups of SCPs were completed first to review the breadth and accuracy of information, and feedback was prioritized and implemented as major updates using Agile processes prior to end user focus groups. We categorized logged in-app feedback using content analysis and thematically analyzed focus group transcripts. In total, 6 focus groups were completed between August 2022 and June 2023; 3 for SCPs (n=9 participants) and 3 for end users (n=7 participants). Four SCPs had previously smoked, and most end users currently smoked cigarettes (n=5), and 2 had quit smoking. The mean duration of focus groups was 58 (SD 10.9; range 46-74) minutes. We identified four major themes from focus group feedback: (1) conversation design, (2) functionality, (3) relationality and anthropomorphism, and (4) role as a smoking cessation support tool. In response to SCPs' feedback, we made two major updates to Quin between cohorts: (1) improvements to conversation flow and (2) addition of the "Moments of Crisis" conversation tree. Participant feedback also informed 17 recommendations for future smoking cessation chatbot developments. Feedback from end users and SCPs highlighted the importance of chatbot functionality, as this underpinned Quin's conversation design and relationality. The ready accessibility of accurate cessation information and impartial support that Quin provided was recognized as a key benefit for end users, the latter of which contributed to a feeling of accountability to the chatbot. Findings will inform the ongoing development of a mature prototype for clinical testing.

Design and Development of a Multimodal Digital Intervention (SHIFT App) to Address Sexual Dysfunction in Hematopoietic Stem Cell Transplant (HSCT) Survivors

Hematopoietic stem cell transplant (HSCT) survivors frequently experience persistent sexual dysfunction, which is associated with impaired quality of life and increased psychological distress. The lack of availability of clinicians with expertise in sexual health limits the capacity to address sexual health concerns in HSCT survivors. Digital health applications may offer a patient-centered and scalable solution to address sexual health concerns in cancer survivors. The objective of this report is to delineate the iterative process of adapting an in-person sexual health intervention into a self-administered digital application called "Sexual Health and Intimacy Following Transplant (SHIFT)" and the refinement of SHIFT using stakeholder feedback. We used a five-step development model to adapt SHIFT that included: (1) implementation of a multimodal bio-psycho-social conceptual framework, (2) development of a comprehensive intervention manual and SHIFT content, (3) translation of the intervention manual into an interactive storyline with a focus on enhancing patient engagement, (4) creation of initial SHIFT wireframes, and (5) refinement of SHIFT through iterative alpha and beta testing. At each step, key stakeholders including HSCT survivors, HSCT clinicians, and experts in sexual health, psychology, and digital health provided iterative feedback. We adapted SHIFT based on our conceptual framework, prior in-person intervention work, and iterative stakeholder feedback in each application development stage. SHIFT incorporates medical information, educational materials, intimacy exercises, and activities to address the multiple etiologies of sexual health concerns in HSCT survivors. SHIFT includes strategies to enhance engagement including gamification, personalization, and incorporation of video from HSCT survivors and clinicians. Based on stakeholder feedback, SHIFT was refined with a focus on inclusivity of gender, sexual orientation, relationship status, and body image concerns. SHIFT is novel, patient-centered digital application to address sexual dysfunction in HSCT survivors. Iterative feedback from key stakeholders including HSCT survivors guided SHIFT adaptation and refinement, to optimize patient engagement and ensure inclusivity. The final prototype of SHIFT was initially acceptable to key stakeholders and is now under further testing in a pilot randomized trial to assess its feasibility and preliminary efficacy for improving sexual health outcomes in HSCT survivors.

Education in Laparoscopic Cholecystectomy: Design and Feasibility Study of the LapBot Safe Chole Mobile Game.

Major bile duct injuries during laparoscopic cholecystectomy (LC), often stemming from errors in surgical judgment and visual misperception of critical anatomy, significantly impact morbidity, mortality, disability, and health care costs. To enhance safe LC learning, we developed an educational mobile game, LapBot Safe Chole, which uses an artificial intelligence (AI) model to provide real-time coaching and feedback, improving intraoperative decision-making. LapBot Safe Chole offers a free, accessible simulated learning experience with real-time AI feedback. Players engage with intraoperative LC scenarios (short video clips) and identify ideal dissection zones. After the response, users receive an accuracy score from a validated AI algorithm. The game consists of 5 levels of increasing difficulty based on the Parkland grading scale for cholecystitis. Beta testing (n=29) showed score improvements with each round, with attendings and senior trainees achieving top scores faster than junior residents. Learning curves and progression distinguished candidates, with a significant association between user level and scores (P=.003). Players found LapBot enjoyable and educational. LapBot Safe Chole effectively integrates safe LC principles into a fun, accessible, and educational game using AI-generated feedback. Initial beta testing supports the validity of the assessment scores and suggests high adoption and engagement potential among surgical trainees.

The PrEP resource: a mobile app for clinicians to facilitate screening, prescription and follow up of pre-exposure prophylaxis in the prevention of HIV.

Background Over 2million people worldwide receive a new HIV diagnosis annually. Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission, but is underprescribed, including in the US. Lack of clinician comfort and knowledge are the most cited reasons for this discrepancy. We aimed to develop a mobile application (app) to address these barriers and improve patient access to PrEP. Methods We established key criteria to develop a point-of-care app that could be utilised in low-resource settings by various clinicians poised to prescribe PrEP therapy. The app underwent two rounds of beta testing and improvement utilising anonymous survey feedback from US physicians in 2023. Results The PrEP Resource tool was developed. Eleven physicians completed the initial survey addressing prescribing practices and app functionality. A total of 27% (3/11) of participants were uncomfortable prescribing PrEP, with the most common reasons being lack of training, unfamiliarity with guidelines and infrequently prescribing the medication. Our follow-up survey, completed by eight physicians, showed that 100% of participants found the app easy to learn and comprehensive enough to initiate PrEP. Conclusion Clinician discomfort due to lack of knowledge and familiarity is the most common reason for not prescribing PrEP. The PrEP Resource is a free tool that guides healthcare professionals through common clinical scenarios regarding PrEP therapy and may improve clinician comfort levels. It can be used in low-resource and low-bandwidth settings typically encountered in lower-middle-income countries where HIV prevalence is the highest. Further study is required to validate its usefulness across different settings.

Usability testing of the Set Brave Goals app, a continence goal-selection app for children with spina bifida

IntroductionThe Set Brave Goals app is the first digital health app (DHA) aimed at helping children with spina bifida (SB) aged 8-17 years old to select and track their urinary and fecal continence goals. Developed by children, parents, providers and researchers, its usability, or appropriateness to a purpose (“user-friendliness”), remains unknown. In an alpha testing stage, our aim was to determine the usability of the app prior to clinical use. MethodsWe recruited children with SB and their parents in clinic and via social media. A recruitment goal of 10 children exceeded industry standard of 5 participants (10 participants are expected to identify approximately 96% of usability problems). Participants downloaded and used the app for a week. They completed a questionnaire, including the System Usability Scale (SUS) and closed and open-ended questions. The SUS is a 10-item validated usability questionnaire most widely used in DHA usability testing (scores range from 0 to 100, 100 representing greatest usability). Median/mean SUS scores for DHAs are 68. Mann-Whitney-U and t-tests were used. ResultsTen children with SB participated (median age: 14 years old, 6 female, 8 shunted, 8 using bladder catheterizations). Twenty parents participated (17 mothers, median age: 42 years old). Median SUS score was 77.5 for children and 73.8 for parents, corresponding to “good” to “excellent” usability (Summary Figure). There were no significant differences between child/parent scores (p=0.69) or those for DHAs (p=0.11). It took a median 5-10 minutes to go through the app (2 parents felt it took too much time). All participants felt the app was easy to understand and use (100%). Most participants would recommend it to children and parents (children: 89%, parents: 80%), and believed it would be valuable to children (90%, 75%) and urologists (80%, 80%). Free text responses related to more varied color schemes, keeping free-text notes within the app and more flexible goal/alarm setting. These changes were incorporated into the app. CommentUsability testing prior to clinical launch identified areas for app improvement. Although this study sample met industry standards, findings are limited by a small group of participants. The app will undergo further refinement during prospective beta testing. ConclusionsThe Set Brave Goals app for children with SB has acceptable usability parameters. This justifies proceeding with wider use to formalize children’s continence goal setting/tracking and testing its value to children with SB and their healthcare providers.

Fuzzing JavaScript engines with a syntax-aware neural program model

Neural network language modeling has become a remarkable approach in the generation of test cases for fuzzing JavaScript engines. Fuzzers built upon neural language models offer several advantages. They obviate the need for manually developing code generation rules, enable the extraction of patterns from high-quality seed sets, and exhibit commendable portability. Nevertheless, existing works confront challenges in three key aspects: diminished language modeling performance attributable to extensive vocabularies, potential semantic errors within generated test cases, and the limitation of black-box fuzzing, which fails to leverage the internal feedback from the target engine.This paper proposes an innovative neural model-based grey-box fuzzing approach for JavaScript engines. We incorporate the context-free grammar of JavaScript into the neural language model to mitigate the challenges associated with extensive vocabularies, thereby enhancing the model’s performance. Furthermore, to enhance the semantic validity of the generated test cases, we introduce semantic constraints into the mutation process. Notably, this work pioneers the integration of grey-box testing into a fuzzer built upon a neural language model, thereby enhancing the exploration of deep paths. Our prototype, PMFuzz, surpasses NNLM-based counterparts in both language modeling performance and test case generation capabilities. PMFuzz demonstrates a high level of competitiveness in exploring the software state space when compared to traditional coverage-guided grey-box fuzzers. In our evaluation, PMFuzz successfully identified 20 new defects within mainstream JS engines. Eight of them have been confirmed and fixed. Moreover, upon applying our method to C compilers, PMFuzz has revealed 11 new defects.

The effects of incorporating dried cashew apple in the diet of broiler chickens on growth performance, total tract digestibility, and gut health

A total of two hundred and ten one-day-old Ross 308 broiler chicks were utilized in this study to investigate the effects of incorporating Dried Cashew Apples (DCA) in the diet of broiler chickens on growth performance, total tract digestibility, and gut health. The birds were weighed and randomly allotted to seven treatment groups with three replicates, each having 10 birds. The experimental design was a (2 X 3) + 1 augmented factorial arrangement in a completely randomized design. Diet D1 (control diet) was a maize-soybean meal-based; diets D2, D3, and D4 comprised 10, 20, and 30% DCA without exogenous enzyme supplementation, whereas diets D5, D6, and D7 included 10, 20, and 30% DCA treated with exogenous enzyme. Data were collected on growth performance, total tract digestibility, and gut morphology. Collected data were analyzed using SAS (2002) and separation of means was done using Duncan’s Multiple Range Tests of the same statistical software. The difference was set at p < 0.05. The study found that birds fed diets containing 10% DCA, with or without enzyme supplementation (D2 and D5), had a significantly higher Average Daily Gain (ADG) compared to those fed the control diet (D1). The ADG of birds fed diets D3 and D6 was similar to that of birds fed the control diet (D1). However, a significant decrease in ADG was observed as the dietary inclusion level of DCA increased to 30%, as seen in birds offered diets D4 and D7. In addition, a significant linear rise (p < 0.05) in Average Daily Feed Intake (ADFI) was seen when DCA was included in the diet. In addition, birds that were given diets containing DCA showed significantly higher nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1), except for birds that were given a diet containing 30% DCA without enzyme supplementation (D4), which showed significantly lower nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1). Ultimately, birds that were given meals containing DCA exhibited a significant enhancement in GIT development compared to birds on the control diet. Based on the findings of this study, it can be concluded that including DCA in the diet of broiler chickens at a level of up to 20% does not have any detrimental effects on their performance.
