Cancer remains a leading cause of mortality worldwide and a significant barrier to improving quality of life across all populations. The protein kinase D family, including PRKD3, has been demonstrated to play a crucial role in cancer development through its involvement in regulating key cellular processes. Although growing evidence highlights the role of PRKD3 in the tumorigenesis of certain cancers, a comprehensive pan-cancer analysis of PRKD3 remains unavailable. To address this, we performed an integrative pan-cancer analysis of PRKD3 using multi-omics datasets from The Cancer Genome Atlas, the Genotype-Tissue Expression project, and cBioPortal. We examined PRKD3 expression, copy number variation, mutation, and DNA methylation, and evaluated their associations with clinicopathological features, patient survival, and diagnostic potential across 33 cancer types. Immune relevance was further assessed through correlations with immune infiltration, checkpoint gene expression, and immunotherapy response-related genomic biomarkers. Our results revealed that PRKD3 expression was highly heterogeneous, showing significant upregulation in liver cancer, gastric cancer, and adrenocortical carcinoma, and downregulation in others. Elevated expression was consistently associated with poor prognosis and increased stromal, neutrophil, and cancer-associated fibroblast infiltration in adrenocortical carcinoma, liver cancer, and stomach cancer, whereas paradoxical associations with favorable outcomes were observed in kidney clear cell carcinoma. PRKD3 expression also correlated with immune checkpoint molecules including PD-1, PD-L1, and CTLA-4, supporting an immunosuppressive role, while context-dependent associations with TMB and MSI highlighted its potential influence on tumor immunogenicity and responsiveness to immune checkpoint blockade. Collectively, these findings identify PRKD3 as a potential context-dependent modulator of tumor biology, prognosis, and immune interactions, underscoring its potential as a biomarker of diagnostic, prognostic, and therapeutic relevance in precision oncology.by Eleni Christoforidou, Jordan S.

Impaired cytoplasmic dynein function has been implicated in amyotrophic lateral sclerosis (ALS) pathogenesis, yet the contributions of spinal interneurons to disease phenotypes remain unclear. We tested the hypothesis that hypomorphic dynein function in cholinergic neurons disrupts the development, survival, or positioning of inhibitory interneuron populations in the lumbar spinal cord. Using ChAT-Cre recombination, we generated four mouse genotypes with graded reductions in dynein activity in ChAT+ cells: Dync1h1+/+ (wildtype), Dync1h1−/+ (hemizygous wildtype), Dync1h1+/Loa (heterozygous Loa mutation), and Dync1h1−/Loa (hemizygous Loa). At 52 weeks of age, lumbar spinal cords (L3–L6) were harvested, cryosectioned, and immunostained for ChAT, GAD-67, Parvalbumin, and Calbindin. Cell counts were performed on confocal images from eight sections per mouse (N = 3 male mice/genotype), and radial distances from the central canal were normalised to gray matter width. Angular distributions were analysed via circular statistics. There were no significant genotype-dependent differences in the numbers of ChAT+, GAD-67+, Parvalbumin+, or Calbindin+ cells, nor in ChAT+ subpopulations (motor neurons versus interneurons) or double‐positive interneuron subsets (e.g., ChAT+–GAD-67+, Parvalbumin+–GAD-67+, Parvalbumin+–Calbindin+). Radial positioning relative to the central canal was similarly preserved across all markers and genotypes. Circular‐median tests revealed statistically significant shifts in mean angle for ChAT+, GAD-67+, and certain double‐positive cells, but these amounted to only 5–10° displacements, translating to lateral shifts of ~10–20 µm, well within single laminar bands, and are unlikely to impact circuit connectivity. Despite substantial motor deficits and hallmark TDP-43 pathology previously seen in these models, impaired dynein function does not precipitate interneuron loss or gross migratory defects in the lumbar spinal cord. Instead, our findings suggest that the primary contributions of dynein to ALS-like phenotypes likely arise from functional disruptions in axonal transport, synaptic maintenance, and neuronal physiology rather than from structural alterations or loss of interneuron populations.by Ana Laura Januário Lelis, Leandro Aparecido Ferreira da Silva, Daniel Moretto Casali, Tiago Leiva, Murilo Chuba Rodrigues, José Paulo Roman Barroso, Pedro Veloso Facury Lasmar, Camila Lisboa Tomaz, Anabelle Jorge Barbosa, Camila Cesario Fernandes Sartini, Johnny Maciel de Souza, Danilo Domingues Millen
This study evaluated the effects of increasing narasin doses on ruminal fermentation, nutrient digestibility, ruminal pH stability, papillae histology, and microbial composition in Angus cattle fed feedlot diets. Three rumen-cannulated Angus steers (average body weight: 680 kg) were assigned to a 3 × 3 Latin square design and received diets containing 13, 20, or 27-ppm of narasin. Each experimental period consisted of 14 days of adaptation followed by seven days of sampling. Ruminal degradability was assessed on days 15–17, apparent digestibility on days 15–19, continuous ruminal pH on days 19–20, and samples for short-chain fatty acids (SCFA), microbiota, and ruminal histology were collected on days 20 and 21. Ruminal degradability was not affected by narasin dose. Digestibility of acid detergent fiber (ADF) was significantly influenced, with the greatest values observed at 27-ppm (P = 0.01). Increasing narasin doses improved ruminal pH stability, as indicated by a linear increase in minimum pH (P = 0.01) and a reduction in the duration of pH below 5.6 (P = 0.10). At 13 ppm, SCFA production, particularly acetate and propionate, increased (P P P = 0.02), and butyrate (P P P = 0.03). Narasin supplementation altered ruminal microbial composition, increasing the relative abundance of Lachnospiraceae and Isotricha while reducing lactic acid–producing bacteria. In terms of ruminal morphology, supplementation with 20-ppm of narasin increased the keratin layer thickness of ruminal papillae (P = 0.02), suggesting enhanced epithelial development. Overall, narasin supplementation modulated ruminal function and microbial ecology, with doses between 13 and 20-ppm providing the most favorable balance between fermentative efficiency and ruminal health in feedlot cattle.Up to 30% of individuals with depression develop persistent depressive disorder (PDD), an often disabling and difficult to treat condition. The Cognitive Behavioural Analysis System of Psychotherapy (CBASP) is the only psychotherapy developed specifically for treating individuals with PDD. While several randomised controlled trials (RCTs) have demonstrated its efficacy in outpatient settings, evidence for its use in inpatient settings remains limited. Pilot studies of CBASP inpatient programmes in Germany have shown promising feasibility and effectiveness; however, no RCTs to date have systematically evaluated their outcomes. This study represents the first RCT to compare the short- and long-term efficacy and safety of CBASP with Behavioural Activation (BA), a first-line psychotherapy for depression, within an intensive multimodal inpatient setting.
In this prospective, multicentre, rater-blinded RCT with an active control group, we aim to recruit 396 adults (aged 18–70 years) with treatment-resistant PDD at eight German university hospitals. Participants will be randomly assigned to receive either (1) CBASP or (2) BA within an intensive treatment programme consisting of 10 weeks acute treatment in an inpatient and/or day clinic setting, followed by 6 weeks of outpatient continuation treatment. Primary and secondary outcome assessments will be conducted at multiple time points: baseline (T0), treatment onset (T1), after 5 and 10 weeks of acute treatment (T2, T3), at the end of continuation treatment (T4, week 16) and every 2 months up to week 64 (T5, naturalistic follow-up).
The primary outcome measure will be the change in depression severity, as assessed by the Hamilton Depression Rating Scale (24-item version), after 16 weeks of treatment (from T0 to T4). Secondary outcomes will include response, remission, deterioration and relapse rates, self-reported depression and anxiety symptoms and additional psychological variables. A cost-benefit analysis will evaluate the health-economic benefits of both interventions. Additionally, this RCT will explore personalised treatment selection and mechanisms of change, including potential moderators and mediators of treatment effects. The findings from this trial are expected to provide clinicians with evidence-based guidance on choosing CBASP versus BA for inpatients with treatment-resistant PDD.
This study has received ethical approval from the ethics committees of all participating university hospitals. All participants will provide written informed consent before enrolment. Study findings will be published in peer-reviewed journals and presented at national and international conferences. We have involved people with lived experience from the earliest pilots onward, using their feedback to refine our study design. Ongoing consultation at conferences and public events has further ensured that our research remains grounded in patient perspectives.
Walking, as a simple, low-cost and easily implemented form of exercise, offers multiple health advantages. The WalkLung trial aims to evaluate the efficacy of a home-based walking exercise and education intervention in promoting early functional recovery after lung cancer surgery.
WalkLung is a multicentre, parallel-group, randomised controlled trial conducted at three hospitals in China, with stratification by study centre. A total of 116 patients with postoperative lung cancer will be randomised in a 1:1 ratio to either the intervention group (home-based walking exercise and education for 4 weeks) or the control group (usual care). The primary outcome is the longitudinal walking difficulty score during the 4-week postdischarge, measured by the validated perioperative symptom assessment for lung surgery scale (0–10 scale), assessed at discharge and weekly for 4 weeks. Secondary outcomes are the 6-min walk test, pulmonary function, complications, physical activity level, quality of life, social functioning, exercise adherence and adverse events. Long-term outcomes (up to 6 months) will be analysed and reported separately. All analyses will use an intention-to-treat approach, with outcome measures analysed as appropriate using generalised estimating equations for repeated measures, and t-tests or 2 tests.
Ethical approval was obtained from the Ethics Committee for Medical Research and New Medical Technology of Sichuan Cancer Hospital (No. SCCHEC-02-2025-091) and all participating subcentres. Written informed consent will be obtained from all participants. The manuscript is based on protocol V.1.0 (2 January 2025). The study findings will be disseminated through peer-reviewed journal publications and conference presentations.

To assess the relation between component rotation in total knee replacement and clinical outcomes.
Prospective, observational cohort study.
Deventer hospital, Deventer, The Netherlands.
498 adults aged 18 years and older undergoing total knee replacement.
Participants underwent Persona posterior stabilised total knee replacement. Femoral and tibial component rotation was measured using low-dose CT scans.
The primary outcome was the change in Oxford Knee Score from baseline to 1 year, analysed in relation to femoral, tibial and combined component rotation.
Binary logistic regression analysis showed no statistically significant association between femoral component rotation (OR=1.04, 95% CI 0.89 to 1.21, p=0.644), tibial component rotation (OR=0.99, 95% CI 0.94 to 1.03, p=0.467), or combined rotation (OR=0.99, 95% CI 0.95 to 1.03, p=0.552), and achievement of the minimal clinically important difference of 5 points for the 48-point Oxford Knee Score.
This prospective study of 498 patients undergoing total knee replacement did not provide evidence of a relation between the rotational alignment of total knee arthroplasty components and clinical outcomes. These findings do not support routine evaluation of rotational alignment as a basis for revision surgery in patients with persistent pain in the absence of mechanical problems.

The international mobility of nurses is a significant component of healthcare systems worldwide, resulting in the global recruitment and adaptation of culturally and linguistically diverse nurses into diverse work environments. CALD nurses face integration challenges, which can potentially compromise their well-being and adjustment to the new setting. Psychological safety is a key component to promoting individual well-being and effective organisational integration.
This systematic review aimed to identify the current evidence on the psychological safety of culturally and linguistically diverse nurses in healthcare work environments and the factors associated with it.
This systematic review was conducted using JBI guidelines. PiCo/PEO format was utilised for inclusion and exclusion criteria, including English/Finnish, without time limitations. The screening process was conducted by two independent researchers, with a third researcher resolving the conflicts. The PRISMA checklist was utilised in reporting. Data were analysed using content analysis for qualitative and data synthesis for quantitative.
CINAHL, PubMed, ProQuest, Scopus and Medic. Search period: 24.10.2024–23.1.2025.
The systematic review yielded 15 qualitative, one mixed-methods and one quantitative article. The content analysis produced 270 codes, 67 subcategories, seven categories and two main categories. Professional growth and acceptance captured inclusion, professional competence and support from colleagues and managers in creating job satisfaction. Marginalised disempowerment reflected factors linked to low psychological safety, contributing to reduced job satisfaction in the workplace.
Healthcare organisations should confront existing inequities on psychological safety in culturally diverse healthcare environments that are structured around professional inequalities to create equitable spaces for CALD nurses. More research is needed to understand psychological safety experiences from the CALD nurse perspective, exploring the equitability of facilitating factors amid systemic disadvantages in the healthcare workplace.

To better understand what enables evidence-based practice, this study investigated contextual factors influencing evidence-based practice in general, and in relation to the implementation of bladder-monitoring guidelines in orthopaedic care.
Convergent parallel mixed method.
This study was part of a hybrid research project across 17 Swedish orthopaedic sites. The data collection (2021–2023) included interviews with orthopaedic staff and patients post-hip surgery, patient survey free-text responses, and a staff survey on organisational context. Data were analysed with deductive content analysis and descriptive statistics, later integrated using a mixed methods approach.
Evidence-based practice was supported by context factors such as staff collaboration and multiprofessional engagement. Staff addressed patient safety and equality by using evidence-based guidelines, but rarely involved the patients. Orthopaedic fast-track procedures positioned patients as passive recipients, while staff voiced a call for a more person-centred context. Positive attitudes, leadership engagement, use of champions, and adequate staffing enabled evidence-based practice, though a shortage in evaluation and high staff turnover hindered its implementation.
Orthopaedic context is characterised by several enabling organisational context factors for evidence-based practice, although patients lacking recognition of their needs and queries justify greater focus on person-centredness and mutual information exchange. Audit and feedback are crucial for improvements, but were lacking in the orthopaedic care context.
Assessments of efforts made to implement evidence-based practice and its outcomes should incorporate nursing care. Slimmed care processes require attention to ensure patient participation.
The orthopaedic care context is enabling for evidence-based practice, although staff are challenged by fast-track procedures with extensive information exchange and insufficient person-centredness.

To explore the practical experiences and perceived needs of healthcare professionals in fostering resilience among bereaved parents.
A qualitative descriptive study was conducted.
Twenty-seven healthcare professionals were recruited from the Paediatric Palliative Care Special Group of the Paediatrics Society of the Chinese Medical Association. The participants included 9 physicians, 7 nurses and 11 social workers from 22 hospitals and 5 community-based services. In-depth interviews were conducted between July and December 2022. Data were analysed using content analysis.
Guided by the Society-to-Cells Resilience Theory, this study identified 10 categories of practical experiences and seven of perceived needs, encompassing multiple levels: society (integrating multidisciplinary resource; preserving relevant cultural tradition; advocating for system enhancements; raising public awareness), community (establishing an accessible support network; fostering an inclusive community; offering proactive community support), family (providing anticipatory guidance; enhancing family cohesion; navigating bereavement resources; providing ongoing follow-up and support), individual (evaluating grief-related experiences; offering tailored personal support; sustaining connections; addressing spiritual needs) and physiological (managing body reactions; maintaining physical well-being).
This study provides insights from healthcare professionals, highlighting practices and identifying significant gaps in current approaches to building resilience in bereaved parents. The findings suggest that resilience is a socially constructed, multidimensional process that can be nurtured through a holistic approach to better support this vulnerable group.
The study's findings lay the foundation for developing targeted interventions to foster resilience among bereaved parents. A holistic, empowering approach is essential to strengthen their coping mechanisms and facilitate healing at multiple levels, ultimately contributing to the creation of a robust, effective support system for this resilient yet vulnerable population.
This study was about the experiences and perceptions of healthcare providers. It was designed and conducted by researchers who were both researchers and healthcare providers.
This study aims to explore occupational burnout among Chinese nurses from two perspectives: first, by comparing changes in emotional exhaustion, depersonalisation and personal accomplishment before and after the COVID-19 pandemic; and second, by identifying long-term work-related stressors and structural factors contributing to burnout.
A mixed-methods approach was adopted, combining a systematic review with qualitative interviews. The qualitative component involved semi-structured interviews with 53 hospital-employed nurses from various departments and regions across China, focusing on the three core dimensions of occupational burnout.
The systematic review included both Chinese and English-language studies published between 2016 and 2023 that used the Maslach Burnout Inventory to assess burnout among nurses. A total of 22 studies met the inclusion criteria, selected independently by two researchers using the JBI critical appraisal tool. In parallel, the qualitative interviews explored nurses' subjective experiences and coping strategies related to work stress, emotional fatigue and professional identity.
Bayesian factor analysis indicated no significant differences in emotional exhaustion (BF01 = 2.202), depersonalisation (BF01 = 2.761) or personal accomplishment (BF01 = 2.747) before and after the pandemic. Qualitative findings revealed that burnout was primarily driven by long-standing systemic stressors, including promotion pressure, clinical workload, organisational demands and work–family conflict. Although many nurses relied on self-regulation strategies to maintain psychological stability, they continued to experience ongoing physical and emotional exhaustion. Some reported emotional numbness, but most retained empathy and a strong sense of responsibility. Their sense of personal accomplishment often stemmed from patient recovery and recognition of professional value.
Occupational burnout among Chinese nurses remained largely stable before and after the COVID-19 pandemic. Its root causes stem from persistent work-related stressors and systemic issues, rather than the pandemic itself. Effective mitigation requires institutional strategies, including better staffing, clear career pathways and sustained emotional support.
Short-term crisis responses alone are insufficient to address enduring burnout. Nursing leadership should prioritise systemic reforms—such as optimising shift schedules, defining promotion channels and integrating regular psychological support—to enhance nurse well-being and care quality.

Equity, Diversity, Inclusion and Accessibility (EDIA) are recognised as core principles in higher education, yet their practical integration into pharmacy education remains underexplored. This review aims to identify the scope of existing research, highlight knowledge gaps and provide valuable insights for pharmacy educators, researchers and policymakers seeking to enhance EDIA integration within pharmacy education.
This protocol describes the methodology for a scoping review to systematically map the existing peer-reviewed literature on EDIA in pharmacy education, focusing on three critical areas: faculty development, curriculum content and teaching strategies. Using the Population, Concept and Context framework, the review will include studies examining faculty members, students and administrators within formal pharmacy education contexts worldwide. The scoping review will adhere to the Joanna Briggs Institute methodology and PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. The search will include peer-reviewed academic studies, accessed through databases such as MEDLINE, Embase, CINAHL, APA PsycINFO, ERIC and Web of Science. Backward snowballing will also be employed. Data will be charted using a predefined extraction tool, and findings will be synthesised and presented in tabular and narrative formats. A pilot search took place in March 2025, and the final search, study selection and data extraction will be conducted from May to December 2025. The subsequent analysis, presentation and interpretation of results are planned thereafter.
Ethics approval is not required. We plan to share findings through a variety of means including professional networks, peer-reviewed journal publications, conference presentations, invited workshops and webinars, on the FPD-Include project website and on our research groups’ university websites.
Hand osteoarthritis (OA) is a prevalent and debilitating joint disorder that impairs daily functioning and quality of life. Current treatments are often inadequate in managing the symptoms and progression of the disease. The cytokine interleukin (IL)-17 has been implicated in the inflammatory processes associated with OA, making it a potential target for therapeutic intervention. This trial aims to evaluate the efficacy of vunakizumab, an IL-17A inhibitor, in reducing pain and improving functional outcomes in patients with erosive hand OA.
This multicentre, randomised, placebo-controlled, double-blind trial will enrol 150 participants aged 30–80 years with symptomatic erosive hand OA. Participants will be randomised in a 1:1 ratio to receive either vunakizumab 120 mg or placebo subcutaneously every 4 weeks for 24 weeks, with a loading dose injection period during the first 4 weeks. The primary outcome is the change in hand pain assessed by the Visual Analogue Scale at 28 weeks. Secondary outcomes include changes in physical function measured by the Functional Index for Hand Osteoarthritis, the Quick Disabilities of the Arm, Shoulder and Hand questionnaire and the Health Assessment Questionnaire, as well as changes in grip strength and radiographic and MRI evaluations of the hands.
Written informed consent will be obtained from all participants. The study was approved by the Ethics Committee of Shanghai Sixth People’s Hospital (2024–217) and will adhere to the Declaration of Helsinki. Research results will be published in peer-reviewed journals.

Long-term motor training is thought to reshape brain organization, yet how golf expertise influences large-scale brain networks remains unclear. Using T1-weighted MRI and an individualized structural covariance network (SCN) approach, we compared 20 expert golfers, 20 novice golfers, and 20 non-golfer controls. Experts showed higher global clustering coefficient and local efficiency than novices, indicating enhanced modular processing. At the nodal level, experts exhibited increased clustering in regions supporting visual–sensorimotor integration (e.g., right supramarginal gyrus, Heschl’s gyrus, and left middle temporal pole), alongside reduced global efficiency in the left calcarine cortex and altered path length in the right cerebellum. Importantly, the clustering coefficient mediated the association between training duration and stroke accuracy. These cross-sectional findings suggest that extensive golf training is linked to a brain network reconfiguration that favors local specialization over global integration—potentially supporting the refined sensorimotor control required in elite performance. This study advances understanding of experience-dependent neuroplasticity by integrating individualized network analysis with behavioral outcomes in motor expertise.Early-life socioeconomic status (SES) increases the risk of poor mental health outcomes in adulthood. However, the mechanistic pathways underlying this relationship remain poorly understood. While addressing socioeconomic inequalities remains a long-term goal, identifying specific mediating pathways could reveal more immediate opportunities for effective interventions.
Using linked administrative data from New South Wales, Australia (1990–2022), we will emulate a target trial examining the relationship between SES at birth and acute mental health admissions and presentations between the ages of 18 and 25 years. An interventional mediation analysis will be used to examine the effect of multiple mediating pathways, including education, housing stability, child protection contact, parental incarceration and justice system involvement, on the outcome. The analysis will estimate direct and indirect interventional effects, quantifying how much of the SES-mental health relationship could be modified by interventions on specific mediators.
This study has received ethics approval from the University of Newcastle (H-2024-0015) and Aboriginal Health and Medical Research Council (2265/24) Human Research Ethics Committees. All dissemination activities will be conducted in accordance with data access agreements and following approval from all relevant data custodians (New South Wales Health System Data Services). Key findings will be communicated to relevant government agencies and policymakers through policy briefs and stakeholder meetings, and publication in appropriate academic journals.
To examine determinants of nurses' adoption of generative artificial intelligence outputs in clinical practice using a technology acceptance model and an integrated structural equation modelling framework.
Cross-sectional online survey.
Registered nurses in mainland China completed an anonymous questionnaire assessing perceived performance benefits, perceived ease of use, perceived information quality, perceived source credibility, social influence, facilitating conditions, adoption intention and adoption behaviour. Structural equation modelling was used to evaluate the measurement model and estimate a primary mediation model in which perceived performance benefits and perceived ease of use predicted adoption intention, and adoption intention predicted adoption behaviour. An integrated model added information quality, source credibility, social influence and facilitating conditions as additional determinants. Sensitivity analyses were conducted using an ordinal estimator to assess robustness.
The analytic sample comprised 330 nurses. In the primary model, higher perceived performance benefits and greater perceived ease of use were associated with stronger adoption intention, and stronger adoption intention was associated with higher self-reported adoption behaviour. The integrated model showed that perceived information quality contributed to adoption intention beyond core expectancy beliefs, while perceived source credibility showed a small direct association with adoption behaviour. Social influence demonstrated a modest association with adoption intention, whereas facilitating conditions showed weaker associations after accounting for other determinants. Model conclusions were consistent across estimation approaches.
Nurses' adoption of generative artificial intelligence outputs is shaped by perceived performance benefits, ease of use and perceived information quality, with adoption intention functioning as the proximal determinant of self-reported use. Implementation strategies should focus on demonstrable workflow gains, reducing interaction burden and strengthening governance and verification to support safe adoption.
Social camouflaging (SC; ie, the concealing of autistic traits to socially assimilate) is associated with poor mental health, self-identity and quality of life outcomes, yet its typology, consequences and contextual triggers remain unexplored in autistic adolescents. Further study is necessary to identify protective factors against the potentially negative outcomes associated with SC to promote long-term well-being.
The current project will investigate SC in youth and its mental health, cognitive and neurophysiological correlates. Camouflaging will be captured by triangulating self-reported and caregiver-reported SC behaviours, as well as SC behaviours in day-to-day contexts using intensive longitudinal methods (ie, daily diaries). Non-autistic, self-identifying autistic and formally diagnosed autistic adolescents aged 15–18 years (N=150) will be recruited. Adolescents and caregivers will complete rating scales to assess mental health, and adolescents will complete in-lab cognitive assessments of attention, executive function, intellectual ability and theory of mind. Brain neurophysiological function and cortisol concentration over time will be measured during the same visit using electroencephalography and hair samples, respectively. Over the following 7 days, adolescents will complete daily diaries using their smartphones. The daily diaries pose survey questions about the type and degree of SC behaviour used within their daily environment, including the social context, individuals who are present and current well-being. Adolescents will also complete brief performance-based cognitive assessments of attention and executive function integrated within the daily diary surveys. Finally, adolescents and their parents will complete a follow-up of SC behaviours and mental health at 3 months. Correlations and regression analyses will be conducted to explore the associations between SC and mental health/cognitive outcomes and how baseline measures of cognition, mental health and SC predict patterns seen on the daily diaries. Multilevel modelling will be used, nesting daily data to capture within-person and between-group differences in contextual predictors of camouflaging behaviour. Results will contribute to current understanding of the typology of camouflaging, as well as inform intervention to mitigate mental health challenges for autistic youth.
This project is approved by the University of Victoria Human Research Ethics Board (#23–0013) and the University of Calgary Conjoint Faculties Research Ethics Board (#23–0641). Informed consent will be obtained from caregivers and adolescent participants, and safety procedures will be put in place to support the adolescent should mental health concerns arise. Results will be disseminated through academic publications and conferences, as well as summarised and communicated to interested participants and relevant stakeholders.
Traditional encounter-based analyses overlook downstream costs and complications that follow emergency department (ED) care. To enable more comprehensive evaluations, we developed standardised episode of care definitions for five common, high-cost conditions: chest pain, congestive heart failure (CHF), pneumonia, chronic obstructive pulmonary disease (COPD) and suicidality.
A two-round modified Delphi panel study was conducted following a literature review and evidence synthesis. Using structured surveys with anonymous feedback, panellists rated candidate criteria. To be retained in the final episode definitions, criteria were required to meet a predefined validity threshold without panellist disagreement. Data were analysed descriptively, and meeting deliberations were recorded and reviewed thematically.
Virtual, supported by an online survey platform.
A multidisciplinary panel of 11 experts in emergency medicine and relevant clinical specialties with 9 members participating in each round.
Criteria to determine inclusion, exclusion (including pre-trigger, post-trigger and event exclusion) and risk-adjustment standards for constructing ED-based episodes of care.
Candidate criteria were presented to the panel by condition: 30 for chest pain, 54 for CHF, 30 for COPD, 79 for pneumonia and 375 for suicidality. Following deliberations and re-rating, the number of valid criteria was reduced, primarily in the episode exclusion category. Thematic analysis highlighted trade-offs between episode exclusion criteria and the use of risk adjustment to account for heterogeneity.
Operational definitions for ED-based episodes of care for five conditions were established. These may support healthcare administrators, policymakers and researchers in evaluating variation in ED care delivery and its downstream cost and outcomes.
To estimate the prevalence and comorbidity patterns of mental health disorders (MHDs) in persons with vitiligo and compare relative risks (RRs) with dermatological diseases (atopic dermatitis and psoriasis) and non-vitiligo comparator cohorts using claims data.
Retrospective matched cohort study using nationwide statutory health insurance claims data.
German statutory health insurance claims (DAK-Gesundheit), 2016–2020.
A 40% anonymised sample of insured persons (N=2 885 984). In 2020, persons with vitiligo (International Statistical Classification of Diseases, Tenth Revision, German Modification L80) were compared with cohorts with atopic dermatitis (L20), psoriasis (L40) and persons without vitiligo. Cohorts were propensity score matched (1:3) by age and sex.
Prevalence of MHDs and RRs across comparator cohorts.
Internal plausibility of expert-informed claims-based MHD case definitions using diagnosis-only versus diagnosis-plus-care criteria.
In 2020, 4 631 persons were diagnosed with vitiligo. Affective disorders and neurotic, stress-related and somatoform disorders showed the highest prevalence, with depressive episodes ranging from 8.9% to 19.2% and somatoform disorders from 5.3% to 17.9% across definitions. In matched comparisons with atopic dermatitis, only a few and inconsistent differences were observed. In contrast, more pronounced and consistent differences were identified in comparisons with psoriasis. Emotional disorders in childhood showed higher risks under the most sensitive case definition (RR=2.29, 95% CI 1.14 to 4.61), whereas hyperkinetic disorders showed consistent effects across all definitions (RR range=1.58–1.93). Compared with persons without vitiligo, risks were higher for social phobia (RR range=2.10–2.81) and anxiety disorders (RR range=1.64–1.93).
Persons with vitiligo show a substantial burden of affective and stress-related MHDs. The mental health comorbidity profile was largely comparable to that of atopic dermatitis, whereas more pronounced differences were observed in comparisons with psoriasis. Claims-based prevalence estimates were sensitive to case definition, highlighting the importance of transparent operationalisation.
