As computational fluid dynamics (CFD) has become more mainstream in production engineering workflows, new demands have been introduced that require high-quality meshes to accurately capture the complex geometries. This evolution has created the need for mesh generation frameworks that help engineers design optimized meshing structures for each new geometry. However, many simulation workflows rely on the experience and intuition of senior engineers rather than systematic frameworks. In this paper, a novel technique for determining mesh convergence is created using machine learning (ML). This method seeks to provide process engineers with a visual feedback mechanism of flow regions that require mesh refinement. The work was accomplished by creating three grid sensitivity studies on various geometries: zero-pressure-gradient flat plate, bump in channel, and axisymmetric free jet. The cases were then simulated using the Reynolds Averaged Navier-Stokes (RANS) models in OpenFOAM (v2306) and had the ML method applied post-hoc using Python (v3.12.6). To apply the method to each case, the flow field was regionalized and clustered using an unsupervised ML model. The ML clustering results were then converted into a similarity score, which compares two grid levels to inform the user whether the region of the flow had converged. To prove this framework, the similarity scores were compared to flow field probes used to determine mesh convergence at key points in the flow. The method was found to be in agreement with the flow field probes on the level of mesh refinement that created convergence. The approach was also seen to provide refinement region recommendations in regions of the flow that align with human intuition of the physics of the flow. Full article

Falls are one of the most common and devastating effects of neurological diseases, especially in patients with stroke outcomes, Parkinson’s Disease (PD), and Multiple Sclerosis (MS). To prevent negative outcomes and guide tailored rehabilitation, it is necessary to identify risk factors early. The current study aims to assess whether and how the risk of falling is related to spatiotemporal and kinematic parameters in stroke, PD, and MS. It also seeks to determine how these factors can help manage patients and identify more personalized and appropriate rehabilitation treatments. Ninety patients with neurological disorders (stroke, PD, and MS) underwent eight weeks of home-based rehabilitation using the ARC Intellicare device or following a paper-based protocol. At baseline (T0) and at the end of the protocol (T2), they were assessed using the Silver Index of the hunova^® robotic platform to evaluate fall risk, and instrumental gait analysis to record spatiotemporal and kinematic parameters of walking. Statistical analysis showed moderate and significant correlations between the Silver Index and gait spatiotemporal parameters such as stance and swing phase, both in affected (T0, p = 0.007; T2, p = 0.017) and unaffected side (T0, p = 0.022; T2, p = 0.008), double support in affected side (T0, p = 0.002; T2, p = 0.005), cycle length in affected (T0, p = 0.007; T2, p = 0.003) and unaffected side (T0, p = 0.008; T2, p = 0.003), and cadence (T0, p = 0.025; T2, p = 0.003) in stroke patients. No significant results emerged in the PD and MS. No population showed significant correlations between the Silver Index and gait kinematic parameters. The Silver Index may reflect distinct patterns of instability in post-stroke gait, but in PD and MS, multiple factors influence the risk of falling that instrumental gait analysis cannot fully capture, requiring a more extensive and multidimensional approach that includes cognitive aspects.

Background/Objectives: Across geographical and cultural contexts, how individuals identify, communicate and help-seek for distress is often shaped by how mental health itself is understood. Insight into how adolescents and adults in their routine environment, such as teachers, understand mental health is crucial for developing context-specific mental health promotion strategies to young people. Sri Lanka, a country that navigates the dual legacies of pre-and-post-colonial mental health frameworks, has this need. The aim was to explore Sri Lankan school-going adolescents’ and their teachers’ perspectives of mental health and its determinants. Methods: Semi-structured interviews were conducted with 28 school-going adolescents in grades 10–12/13 and 14 of their school teachers, from seven secondary schools in Gampaha District, Sri Lanka. Interviews were transcribed, translated, coded inductively and analysed thematically. Results: All participants drew on culturally meaningful language that is rooted in Buddhist perspectives to conceptualise mental health. Causes and risk factors of poor mental health were attributed to individual, immediate environmental and structural factors. School environment played a central role in exacerbating other risk factors. Adolescents exhibited more knowledge of informal care avenues for mental health-related concerns. Conclusions: Findings highlight several implications including opportunities to leverage culturally contextualised language/frameworks when promoting mental health to Sri Lankan adolescents, diversifying mental health research and initiating school-based mental health programmes that integrate mental health promotion into routine educational practice to transform learning institutions across Sri Lanka to become mental health-promoting schools.

Adolescent sexual assault survivors have myriad post-assault needs. However, if and how they access resources to attend to those needs can be complicated due to their legal status as minors and child abuse mandatory reporting policies. Such policies that require specific entities to be notified when a sexual assault involving a minor has occurred might deter adolescents from seeking post-assault care. However, no studies to date have examined how mandatory reporting laws inform adolescents’ post-assault decisions and experiences. Through semi-structured qualitative interviews with twenty-one survivors of adolescent sexual assault in one Northeastern US state, we found that mandatory reporting actively deterred sixteen survivors from seeking formal help; would have deterred two survivors from seeking formal help had they known about it; and was a nonissue for three survivors who chose to seek formal help in an attempt to have very specific needs met. Survivors of adolescent sexual assault had serious concerns about losing agency and control and about unwanted involvement from police, parents, and child protective services. Individual providers, organizations, and whole communities must seriously consider the potential harm of mandatory reporting policies and think creatively and collaboratively alongside adolescent survivors to ensure they can access the care they need and deserve.

Psychological distress impacts a large portion of the general population. While effective treatments are available, few seek them out. This lack of treatment seeking may be due to several factors, particularly low mental health literacy (MHL). MHL is the knowledge an individual has regarding psychological disorders and their symptoms, treatments, and where to seek appropriate help when identified. The capacity to pay attention to present-moment experiences in MHL translates to the qualities of dispositional mindfulness (DM), the capacity to pay non-judgmental attention to present-moment experiences. The purpose of the present study was to evaluate the reliability and preliminary convergent validity of a newly developed, vignette-based assessment of psychological disorder recognition. A total of N = 299 participants were recruited via TurkPrime and completed measures of DM (FFMQ), MHL (MHLS), depression (PHQ-9), anxiety (GAD-7), and treatment-seeking attitudes (MHSAS). Participants were subsequently asked to read newly created vignettes based on ICD-11 criteria of major depressive, generalized anxiety, social anxiety, bipolar disorders, post-traumatic stress disorder, and schizophrenia. Participants then responded to questions assessing the recognition of disorder presence and identification. The vignettes with accompanying questions were titled the Psychological Disorder Recognition—Vignette (PDR-V) task. The PDR-V evidenced a Kuder–Richardson Formula 20 (KR-20) of 0.83, indicating excellent internal consistency. Independent sample t-tests indicated that participants with prior psychotherapy exposure, a history of mental health diagnosis, and, unexpectedly, those reporting lower education levels and no current mindfulness practice, scored significantly higher on the PDR-V. Spearman correlations revealed that higher scores on a validated MHL scale and specific facets of DM (describe, act with awareness) were positively correlated with PDR-V scores. Bipolar disorder evidenced the highest recognition as a psychological problem broadly, while social anxiety had the highest specific disorder identification accuracy rates. Generalized anxiety disorder had the lowest recognition and identification accuracy. While the PDR-V demonstrated promising preliminary psychometric properties, it also observed anomalies that warrant further investigation, as findings are limited by its cross-sectional nature. These findings suggest that the PDR-V is a versatile tool for differentiating the presence of a problem and accurately identifying the condition, supporting its potential as a reliable and sound measure.

Background: Early relational health is critical for childhood development, and disruptions in infant-caregiver trust can heighten risk. MERTIL for Parents is a brief, universal, online program designed to build parental understanding of relational trust and its role in infant development. This pilot study is the first evaluation of the program. Objectives: To evaluate the acceptability and short-term outcomes of MERTIL for Parents. Methods: Seventy-three parents (n = 69 mothers) of children aged 0–5 years, referred by practitioners, completed the program and online questionnaires at baseline (N = 73), post-intervention (n = 50), and three-month follow-up (n = 25). Results: The program demonstrated high acceptability: 98% of parents who engaged with the program found the content useful, 92% felt the length was appropriate, and all would recommend it to others. Program completion and satisfaction did not vary by sociodemographic or psychosocial characteristics. At three-month follow-up, parents reported significant improvements in their enjoyment of the parent–child relationship (p < 0.001), attunement to their child (p < 0.001), parenting confidence/competence (p = 0.004 and p = 0.003), help-seeking amenability (p < 0.001), and a reduction in irritability toward the child (p < 0.001), with medium to large effect sizes. No significant changes were observed for items assessing reflective functioning or perceived rejection. Conclusions: MERTIL for Parents shows strong acceptability and promising preliminary outcomes as a scalable, attachment and trauma-informed intervention supporting early relational health. Future research should examine long-term impacts and evaluate broader implementation across diverse families and service contexts. Full article

This contribution presents an improved ductile fracture indicator that is dependent on the normalized third invariant and the plastic strain at fracture, which is in turn dependent on the stress state of the material. Lemaitre’s damage model is used to numerically evaluate the location and level of displacement required to initiate ductile fracture of the alloy. Along with this analysis, the constitutive model based on Gao’s criterion was implemented, to which the fracture indicator was coupled. The proposed fracture indicator is considered a damage denominator function dependent on the normalized third invariant and the plastic strain at the fracture. This damage denominator function seeks to regulate the rate of evolution of the degradation of the material according to its state of stress and level of ductility, which makes the indicator, coupled with the post-processing step of Gao’s model, satisfactorily predict the correct level of force, the appropriate location, and the displacement necessary for the fracture of the material. The predictions made with the help of the indicator were compared to the performance of Lemaitre’s model. In addition, specimens that describe the low triaxiality ratio were evaluated using AISI 4340 alloy at different ductility levels. The new indicator proved to be more advantageous in predicting the mechanical behavior in the fracture of the material for different types of loads, allowing a good estimate of the displacement in the fracture and the levels of force.

Background/Objectives: Pediatric mental health is a major public health concern worldwide and primary care providers struggle to meet the growing demand for mental healthcare. Child Psychiatry Access Programs have emerged to fill gaps in primary care provider (PCP) training, confidence, and workflow support. This study aimed to describe the iterative development of a Child Psychiatry Access Program and present initial findings on its reach and feasibility in supporting PCPs. Methods: The Practical, Robust Implementation and Sustainability Model (PRISM) implementation framework guided the development and evaluation of the program. Pre-implementation surveys and invested partner interviews informed the creation of a multidisciplinary program comprising three components: (1) consultation services and resource navigation, (2) education and training, and (3) provider care guides. The program was then implemented, and reach was assessed via consultation calls, attendance at education and training series, resource navigation encounters, and care guide usage. Feasibility was evaluated through pre- and post-series self-reported ratings across six learning objectives. Results: Pre-implementation evaluation indicated high provider interest across all educational modalities. The resulting program included consultation services, education and training, resource navigation, and provider care guides. Educational trainings led to significant improvements in self-reported knowledge and confidence across six learning objectives, including assessment, treatment planning, family engagement, and navigating local resources. Resource navigation primarily facilitated ongoing management within the primary care setting, with PCPs retaining care in the majority of cases. Engagement with the Colorado Care Guide demonstrated sustained reach, with over 4600 page views from 1300 active users, reflecting broad and ongoing utilization of program resources. Consultation call data mirrored these trends, highlighting both frequently addressed diagnoses and expanding program reach over time. Conclusions: Child psychiatry access programs help support access to youth mental health care in the primary care space and offer potential solutions to workforce limitations during an era of increasing mental health concerns in youth and teens. Findings from this implementation may inform adaptation of child psychiatry access programs in other regions seeking to expand mental health support for children and adolescents in primary care settings.

Background/Objectives: In today’s rapidly evolving healthcare landscape, fostering a culture of innovation and continuous improvement is essential—especially within a nursing association that leads individual and organizational credentialing. Methods: Colleagues from the American Nurses Enterprise (ANE) Innovation Department and the Institute for Nursing Research and Quality Management collaborated to develop the Culture of Innovation and Quality Model^TM. This process involved conducting a literature review, developing a survey instrument, and administering a pilot pre-survey to ANE employees to collect baseline data. Future research will include a comparison with a post-survey after interventions aimed at strengthening the culture of innovation and quality. Results: The results of the pilot pre-survey were high overall and guided the team in identifying areas with the greatest opportunities for improvement. Based on these findings, interventions are being developed that will be implemented at ANE to enhance the practice of and promote the synergy between innovation and quality. Conclusions: Achieving and sustaining high-quality standards of care and advancing the professional development of nurses requires a culture where staff feel safe and have opportunities to create, innovate, improve, and learn. This will help promote an environment where people thrive while ensuring that the nursing profession and practice remain cutting-edge and aligned with emerging technologies and evolving healthcare complexities. The Culture of Innovation and Quality Model^TM may provide a blueprint for organizations who seek to advance innovation and quality knowledge, engagement, and practices and assist their employees in providing better service to colleagues, partners, and customers while adapting to the evolving healthcare environment.

AI-powered full-site web generation tools promise to democratize website creation for novice users. However, their actual usability and accessibility for novice users remain insufficiently studied. This study examines interaction barriers faced by novice users when using Wix ADI to complete three tasks: Task 1 (onboarding), Task 2 (template customization), and Task 3 (product page creation). Twelve participants with no web design background were recruited to perform these tasks while their behavior was recorded via screen capture and eye-tracking (Tobii Glasses 2), supplemented by post-task interviews. Task completion rates declined significantly in Task 2 (66.67%) and 3 (33.33%). Help-seeking behaviors increased significantly, particularly during template customization and product page creation. Eye-tracking data indicated elevated cognitive load in later tasks, with fixation count and saccade count peaking in Task 2 and pupil diameter peaking in Task 3. Qualitative feedback identified core challenges such as interface ambiguity, limited transparency in AI control, and disrupted task logic. These findings reveal a gap between AI tool affordances and novice user needs, underscoring the importance of interface clarity, editable transparency, and adaptive guidance. As full-site generators increasingly target general users, lowering barriers for novice audiences is essential for equitable access to web creation. Full article

Background/Objectives: Effective teamwork is crucial for minimizing human error in healthcare settings. Medical teams, typically composed of physicians and nurses, supported by auxiliary professionals, achieve better outcomes when they possess strong collaborative competencies. High-quality teamwork is associated with fewer adverse events and complications and lower mortality rates. Based on this background, the objective of this study is to analyze the perception of non-technical skills and immediate learning outcomes in interprofessional simulation settings based on E-CRM items. Methods: A cross-sectional observational study was conducted involving participants from the official postgraduate Medicine and Nursing programs at the Catholic University of Murcia (UCAM) during the 2024–2025 academic year. Four interprofessional E-CRM simulation sessions were planned, involving randomly assigned groups with proportional representation of medical and nursing students. Teams worked consistently throughout the training and participated in clinical scenarios observed via video transmission by their peers. Post-scenario debriefings followed INACSL guidelines and employed the PEARLS method. Results: Findings indicate that 48.3% of participants had no difficulty identifying the team leader, while 51.7% reported minor difficulty. Role assignment posed moderate-to-high difficulty for 24.1% of respondents. Communication, situation awareness, and early help-seeking were generally managed with ease, though mobilizing resources remained a challenge for 27.5% of participants. Conclusions: This study supports the value of interprofessional education in developing essential competencies for handling urgent, emergency, and high-complexity clinical situations. Strengthening interdisciplinary collaboration contributes to safer, more effective patient care. Full article

Around the world, many post-conflict societies face the pressing challenge of reintegrating former combatants, especially women, into community life in ways that promote peace and sustainable development. Educational strategies that foster Social Innovation, Entrepreneurship, and Complex Thinking are increasingly recognized as essential tools in this process, helping to rebuild social cohesion and empower local leadership. This study evaluates the impact of the SEL4C methodology on strengthening key competencies in Social Entrepreneurship, Innovation, and Complex Thinking among 49 women signatories of the Peace Agreement in Colombia, who currently live in the Mariana Páez Territorial Training and Reincorporation Space (ETCR). Through a pre- and post-intervention design using validated instruments and statistical analyses (paired t-tests and effect size calculations), the study found significant improvements in areas such as Social Awareness, Social Innovation, and Scientific Thinking. Although the gains in Complex Thinking were moderate, the results show that the methodology effectively enhanced leadership skills and the ability to address systemic challenges—both crucial for successful reintegration. In practical terms, the findings support the use of SEL4C by organizations working in peacebuilding, educational institutions, and public programs that seek to empower women in vulnerable contexts. The methodology’s adaptability and evidence-based structure make it a valuable resource for designing participatory training processes focused on innovation, sustainability, and community transformation.

As survival rates for teenagers and young adults (TYAs) with cancer exceed 80%, they are living longer post treatment, yet often experience prolonged health and quality of life concerns. Many TYAs also experience unmet support needs. This study aimed to identify TYAs support needs following treatment at a UK hospital and explore how and when TYAs prefer to receive support. This study involved two phases: Phase 1 involved semi-structured interviews with 16 TYAs, 1–6 years post-treatment, aged 16–25 years at time of treatment completion and examined their experiences of support services, and preferences for future care. Phase 2 consisted of co-design workshops with eight TYAs and feedback from five healthcare/allied professionals (HCAPs) to refine and develop recommendations. Phase 1 findings revealed six key themes: (1) survivorship as disrupted continuity; (2) negotiating legitimacy and relational safety in help seeking; (3) support offered vs. support sought: pathways of referral and self-initiation; (4) emotional readiness as context dependent and non-linear; (5) support as an ecosystem, not a moment; and (6) personalised autonomy in support engagement. Phase 2 findings informed recommendations that emphasise the importance of flexible, personalised, and accessible post-treatment support, with pathways of care/support that can adapt to TYAs changing needs and preferences over time.

Background: Sexual violence against adolescents and young people (AYP) remains a public health concern. This study explores patterns of sexual violence and help-seeking behaviour as well as their associated risk/protective factors with guidance of a technical package (INSPIRE) designed to reduce sexual violence in low-resource settings. Methods: The 2019 Violence Against Children Survey (VACS) dataset comprises 788 males and 1344 females. After describing the prevalence and patterns of sexual violence and help-seeking behaviour (informal disclosure, knowledge of where to seek formal help, seeking formal help, and receipt of formal help) among 13- to 24-year-old AYP, logistic regression models were then fitted to predict past-year sexual violence and informal disclosure among adolescent girls and young women (AGYW). Results: More young women than young men informally disclosed sexual violence experience (46% versus 23%). Gender inequitable attitudes [AOR 3.07 (1.10–8.56); p = 0.03], experiencing emotional violence at home [AOR 2.11 (1.17–3.81); p = 0.01] and cyberbullying [AOR 5.90 (2.83–12.29); p = 0.00] were identified as risk factors for sexual violence among AGYW. Life skills training [AOR 0.22 (0.07–0.73); p = 0.01] and positive parental monitoring [AOR 0.31 (0.10–0.99); p = 0.05] were found to be protective against sexual violence among AGYW. Positive parental monitoring [AOR 3.85 (1.56–9.46); p = 0.00] was associated with an increased likelihood of informal disclosure among AGYW. Conclusions: As Kenya intensifies efforts towards sexual violence prevention, this study underscores the need to develop and strengthen policies and programs on life skills training, cultural norms, and positive parenting, as well as improve awareness and access to post-violence response and support services.

Barriers to help-seeking behaviors in transgender populations in non-Western contexts are both understudied and poorly understood. Using a quantitative cross-sectional design, this study examined the psychological help-seeking attitudes of 109 transgender persons from Pakistan in relation to their psychological distress and attitudes toward sexuality. This research further identified which components of distress (stress, anxiety, or depression) were stronger predictors and assessed the role of particular demographic/behavioral factors in help-seeking attitudes. Participants completed three validated assessment tools translated into Urdu: Beliefs about Psychological Services Scale, the Depression, Anxiety, and Stress Scale (DASS-21), and the Sexual Attitude Scale. The results indicated that psychological distress predicted expertness and intent but not stigma tolerance. Post hoc analysis using DASS-21 subscales revealed that stress and anxiety were the stronger predictors of attitudes related to expertness and intent. The Sexual Attitude Scale marginally predicted stigma tolerance directly and also moderated the relationship between psychological distress and help-seeking attitudes for stigma tolerance. Finally, a role for demographic/behavioral factors—possibly serving as a proxy for mental health literacy—was identified for stigma tolerance. These findings reiterate the importance of tailored mental health awareness initiatives within the transgender community in non-Western settings and highlight the need for qualitative research to further understand the dynamics of psychological distress along with other linked factors.
