Social cognition, encompassing theory of mind (ToM), facial affect recognition, and mentalising under social load, is impaired across several neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), developmental language disorder (DLD), and intellectual disability (ID). These impairments are plausibly downstream of neurochemical processes, particularly serotonergic, dopaminergic, neuropeptidergic, and excitatory-inhibitory modulation of prefrontal-temporal-limbic circuits, although this pathway is indirect and moderated by age, language, cognitive ability, and comorbidity. Despite this, performance-based social cognition is rarely positioned as a primary or co-primary endpoint in NDD pharmacotherapy trials. The predominant standard, the Aberrant Behavior Checklist Irritability subscale and its caregiver-rated relatives, indexes reactive behavioural output that may be construct-distant from the mechanisms through which several contemporary agents are hypothesised to act. This narrative review advances a conditional thesis: endpoint-mechanism misalignment is one plausible contributor to the uninterpretability of certain null trials, alongside insufficient power, sample heterogeneity, unverified target engagement, dosing limitations, high placebo response, and genuine inefficacy. We synthesise condition-specific social-cognitive profiles with graded evidence, the neurobiological substrates across mechanism classes, and a three-tier framework positioning social cognition as a co-primary endpoint for mechanism-matched agents and as a prespecified secondary or moderator variable otherwise. We set out the measurement and regulatory preconditions fit-for-purpose validation, adequate test-retest reliability, practice-effect control, and defined meaningful change that must precede such repositioning. We do not claim ToM should replace existing endpoints or that it suits all NDD trials.

PURPOSE: Cardiovascular diseases (CVD) are a leading cause of mortality in Iran and globally. This study aimed to provide more accurate estimates of associations between risk factors and CVD mortality by applying competing risk models within the Tehran Lipid and Glucose Study cohort.
METHODS: In this prospective analysis, 7,529 individuals aged ≥ 30 years without prevalent CVD were followed for a median of 19.87 years. The primary outcome was CVD mortality (n = 311), with non-CVD death as the competing event (n = 592). Analyses were stratified by sex and age (< 65 vs. ≥65 years). Cause-specific and Fine-Gray models estimated hazard ratios for diabetes, hypertension, hypercholesterolemia, smoking, and body mass index.
RESULTS: Diabetes and hypertension were the strongest predictors of CVD mortality across most subgroups. In the Fine-Gray model, diabetes showed the greatest impact in women < 65 years (HR: 4.83, p < 0.001), while hypertension showed the strongest association in women ≥ 65 years (HR: 3.32, p < 0.001). Hypercholesterolemia was associated with increased CVD mortality exclusively in women < 65 years (HR: 1.79, p = 0.02). Body mass index showed no significant association.
CONCLUSION: Diabetes and hypertension are the predominant risk factors for CVD mortality in the presence of competing risks, with effect magnitudes varying by sex and age. Applying competing risk models is essential for accurate risk estimation and targeted prevention in populations with high competing mortality burden.

BACKGROUND: Respiratory syncytial virus (RSV) is a major cause of respiratory morbidity in adults, particularly among older individuals and those with comorbidities. The DAN-RSV trial was initiated to evaluate bivalent RSV prefusion F (RSVpreF) vaccine effectiveness in preventing RSV-related hospitalizations.
METHODS: DAN-RSV is a large-scale, pragmatic, randomized clinical trial that enrolled participants during the 2024/2025 (Danish adults aged ≥60 years) and 2025/2026 (adults aged ≥18 years in Denmark and Galicia, Spain) Northern hemisphere winter seasons. In Denmark, nationwide registries and the national electronic messaging system were used to identify and recruit eligible citizens; individuals could provide electronic informed consent remotely or in-person. In Galicia, participants were recruited via text message invitations and consented on-site.
RESULTS: During the initial 2024/2025 season, 131,379 Danish adults aged ≥60 years were enrolled. Following lower-than-expected event accrual and expansion of the EU indication to adults 18 years and older, the trial was extended to continue enrollment of adults aged ≥18 years across Denmark and Galicia, Spain during the 2025/2026 RSV season. Key protocol updates include expansion of the eligibility criteria to adults aged ≥18 years, inclusion of an additional study site within the integrated public healthcare infrastructure of Galicia, Spain, and an increase in the planned sample size to up to approximately 690,000 participants across both seasons. The randomization strategy (1:1 to RSVpreF vaccine or no vaccine), primary endpoint (RSV-related respiratory tract disease hospitalization), and statistical framework, including intention-to-treat analyses and hierarchical testing, remain unchanged.
CONCLUSION: The extension of the DAN-RSV trial is expected to improve statistical precision, enhance generalizability, and strengthen the robustness of the effect estimates. The updated design will provide reliable randomized evidence on bivalent RSVpreF vaccine effectiveness to inform clinical and public health decision-making.

The evolution from critical limb ischemia to chronic limb-threatening ischemia (CLTI) necessitates a reevaluation of clinical trial endpoints. Traditional measures like hemodynamic indices and lesion patency inadequately reflect CLTI complexity or patient-centered outcomes. This article explores the limitations of conventional endpoints and proposes a modified definition of clinically-driven target lesion (TL) revascularization (CD-TLR) that addresses inflow, TL, and outflow disease. By incorporating a more comprehensive assessment of vascular health and prioritizing patient-relevant outcomes, this modified CD-TLR definition may better reflect modern CLTI management strategies and improve clinical relevance of trial results in this challenging patient population.Clinical ImpactThe evolution from CLI to CLTI requires reassessing how we measure treatment success in clinical trials. This review identifies why traditional endpoints like hemodynamic indices, lesion patency, and CD-TLR may not adequately inform clinical decision-making. The importance of measuring outcomes that directly impact patient quality of life will help clinicians better evaluate and apply clinical trial results. An emphasis on limb salvage, wound healing, and functional outcomes, rather than surrogate endpoints alone, will lead to more informed treatment decisions and improved CLTI management strategies.

Adaptive designs are frequently used to adjust sample sizes based on interim data, ensuring reliable conclusions while protecting resources. To maximize trial efficiency, design parameters can be optimized to minimize an objective function (e.g., the expected sample size) while rigorously controlling overall error rates or further operating characteristics. However, existing methodological guidance for optimal adaptive designs mainly focuses on normally distributed data or discrete optimizations for binary data, leaving a limited practical framework to practitioners who work with other common endpoint types. We address this by demonstrating how the asymptotic normal approximations of standard test statistics enable the optimization framework to be systematically applied across diverse endpoint types, including binary and time-to-event data. Furthermore, we highlight critical pitfalls in using optimal adaptive designs for two-sided testing. The results demonstrate that optimizing design parameters can substantially decrease expected sample sizes and improve conditional power compared to standard group-sequential designs. Using this guidance, we aim to enable researchers to efficiently plan clinical trials in a broad spectrum of clinical settings, a factor that is especially crucial in rare disease research where only limited patient populations are available.

Sample size re-estimation (SSR) can be a powerful tool to ensure that a clinical trial meets its pre-specified power requirements when uncertainty regarding a design parameter exists at the planning stage. However, long-term primary endpoints can be harmful to the efficiency of this trial design. If recruitment is continued while treatment outcomes are awaited, long delays can potentially lead to a large number of ‘pipeline’ participants being recruited in the trial that do not contribute to the interim analysis. This may lead to a larger number of recruited participants than are actually deemed required, resulting in an over-powered trial with high cost. This paper studies the exact impact of such outcome delay on the efficiency of ‘internal pilot’ type SSR designs. The distribution of the final sample size post SSR is obtained under various delay lengths for both continuous and binary outcome data; how delay impacts the precision of the final sample size estimate is then discussed. Precisely, the impact of delay on this precision is assessed through RMSE, as well as two more novel metrics, termed the delay impact and cost. The results indicate that with an increase in delay length, the delay impact increases, inflating average sample size and power. However, the severity of the effect of delayed outcomes depends highly on the exact trial setting. Trials where the re-estimated sample size is smaller than originally planned suffer the most from delayed outcomes, often leading to an over-powered trial. However, the impact of delay is substantially less if the originally planned sample size remains smaller than the re-estimated sample size.

Hepatocellular carcinoma (HCC) imposes a substantial health burden in China. Finotonlimab plus bevacizumab recently prolonged progression-free survival (PFS) and overall survival (OS) vs. sorafenib, but its economic value remains unknown. Here we evaluated the cost-effectiveness of finotonlimab plus bevacizumab vs. sorafenib from the Chinese healthcare system perspective. Parametric survival models were fitted to extrapolate PFS and OS. Total costs, life-years (LYs), quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), incremental net monetary benefit (INMB), and incremental net health benefit (INHB) were estimated at a willingness-to-pay (WTP) threshold of $27,906 per QALY. Uncertainty was evaluated by one-way and two-way sensitivity analyses, probabilistic sensitivity analysis (PSA), subgroup analyses, scenario analyses, and price simulations. In the base-case analysis, sorafenib yielded 1.74 LYs and 1.25 QALYs at a total cost of $10,303.10, whereas finotonlimab plus bevacizumab yielded 3.01 LYs and 2.18 QALYs at a total cost of $58,595.49. Compared with sorafenib, the combination increased costs by $48,292.39 and generated gains of 1.27 LYs and 0.93 QALYs, resulting in ICERs of $38,203.46 per LY and $51,899.31 per QALY. INMB (-$22,325.82) and INHB (-0.80 QALYs) were negative. Sensitivity analyses identified PFS utility and bevacizumab cost as key drivers, but all ICERs remained above the WTP threshold. In PSA, the mean ICER was $50561.81 per QALY, and the probability of cost-effectiveness was 0% at the prespecified threshold. Based on the assumptions and inputs used in the present model, finotonlimab plus bevacizumab was unlikely to be cost-effective compared with sorafenib at the prespecified WTP in China.

AIMS: Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative therapy for patients with hematologic malignancies, but its success is limited by graft‑versus‑host disease (GVHD), which carries considerable clinical and economic burden. A cost-effectiveness model was developed to evaluate whether the higher upfront costs of allogeneic regulatory T cell-based immunotherapy with HSPC and T cells-vldq (Tregzi [Orca-T; Orca Bio, Menlo Park, CA, USA]) are offset by reductions in GVHD and associated healthcare costs compared with conventional allo-HCT using TAC/MTX or PTCy.
METHODS: A three-state partitioned survival model (relapse-free, relapsed, and dead) with a lifetime horizon and monthly cycles was developed. Overall survival and relapse-free survival data from the Phase 3 Precision-T study (ClinicalTrials.gov Identifier NCT05316701) were incorporated using a cure-mixture modeling approach to estimate long-term survival, relapse status, and cure fraction for patients. Costs included transplant procedure, GVHD management, infection management, and terminal care. Outcomes included life-years, quality-adjusted life-years (QALYs), and direct healthcare costs. Both costs and outcomes were discounted at 3% annually. A scenario analysis was conducted to determine the cost-effectiveness of Orca-T vs allo-HCT with PTCy for GVHD prophylaxis, and sensitivity analyses were conducted to test the uncertainty of the model inputs.
RESULTS: Orca‑T was associated with lower lifetime costs ($1,026,856 vs $2,170,875) and higher QALYs (15.28 vs 13.00) than conventional allo‑HCT with TAC/MTX, yielding cost savings of $1,144,019 and a gain of 2.28 QALYs per patient. GVHD-related costs were substantially lower with Orca‑T ($495,447 vs $1,998,621). Compared with PTCy, Orca‑T remained dominant, with cost savings of $158,144, a gain of 2.85 QALYs, and lower GVHD-related costs ($476,448 vs $999,945).
CONCLUSIONS: Orca‑T reduced costs and increased QALYs versus conventional allo‑HCT with TAC/MTX or PTCy, driven by lower GVHD and infection burden. These findings support Orca‑T as a high‑value treatment option.

BACKGROUND: Healthcare overuse, including unnecessary diagnostic testing and procedures, contributes to patient harm, increased healthcare costs, and resource waste. The Choosing Wisely initiative aims to reduce low-value care through evidence-based recommendations. However, limited evidence exists regarding the safety and effectiveness of implementing Choosing Wisely recommendations in intensive care settings.
METHODS: The WICH-ICU is a registry-based stepped-wedge cluster randomized controlled trial designed to evaluate the implementation of specific Choosing Wisely interventions in Swedish intensive care units (ICUs). The study will include adult patients treated in participating Swedish ICUs. The intervention consists of three parts of the Choosing Wisely recommendations: (1) reduced frequency of arterial blood gas sampling, (2) reduced routine laboratory testing, and (3) reduced routine chest radiography. The primary outcome is 30-day mortality. Secondary outcomes include ICU length of stay, duration of mechanical ventilation (invasive and noninvasive), continuous renal replacement therapy duration, and ICU readmission within 72 h. Intervention data, testing intensity (arterial blood gas samples, laboratory tests, and chest radiographs per patient-day), will be collected through local monitoring, while outcome data will be obtained from the Swedish Intensive Care Registry (SIR). The stepped-wedge design allows each participating ICU to serve as its own control, with randomized timing of intervention implementation.
DISCUSSION: This study will provide evidence on the safety and effectiveness of implementing Choosing Wisely recommendations in intensive care settings. The stepped-wedge cluster randomized design minimizes contamination while allowing all participating sites to eventually receive the intervention. The results will inform evidence-based de-implementation strategies in critical care.

The success of inflammatory bowel disease (IBD) clinical trials is strongly influenced by study design and disease-specific operational challenges. Over the past decade, however, IBD clinical trials face slow enrolment, poor retention, accumulating costs and limited representativeness. Trials are further constrained by protocol and operational complexity, financial pressures and regulatory requirements. Carefully selected and optimised trial designs may address the inherent challenges of IBD research and should take into account the patient profiles under investigation, mode of action and speed of onset of effect of the investigational product, among other factors. This narrative review discusses four key study design strategies for IBD clinical trials, including treat-through maintenance, responder re-randomisation, Master Protocol approaches (basket, umbrella and platform trials) and Bayesian methodologies. Treat-through maintenance designs are effective at evaluating sustained efficacy and real-world durability, whereas responder re-randomisation approaches are widely used in drug registration programmes to distinguish induction and maintenance effects for regulator clarity. Master Protocol designs may improve efficiency and reduce placebo exposure, while trials using Bayesian methodologies can strengthen interpretation of efficacy and safety outcomes, particularly in early-phase or complex studies. Key considerations within protocols include the use of co-primary endpoints, selection of secondary/exploratory endpoints, control group design and integrating digital health technologies, among others. Strategic application of innovative methodologies can improve trial delivery and enhance data robustness and interpretability, thus supporting more efficient development of effective therapies for patients with IBD.

BACKGROUND: Adolescent depression is associated with substantial health and economic burden. Preventive interventions that strengthen parenting skills show promise in reducing depressive symptoms and improving adolescent well-being. However, evidence on the cost-effectiveness of scalable online parenting interventions remains limited.
OBJECTIVES: To evaluate the cost-effectiveness of an online personalised parenting (PP) programme - Partners in Parenting - designed to prevent affective disorders in high-risk adolescents, compared with a standard educational package.
METHODS: This trial-based economic evaluation was conducted alongside a randomised controlled trial of 512 parent-adolescent dyads (256 per arm). Analyses adopted UK public sector and societal perspectives over 15 months. Costs (2022-2023 GBP) were collected prospectively. Utilities from EQ-5D-Y and CHU9D were used to estimate quality-adjusted life-years (QALYs). The base case used bivariate regression of costs and QALYs with multiple imputations under intention-to-treat. Incremental cost-effectiveness ratios, net monetary benefits, and cost-effectiveness acceptability curves were estimated. Sensitivity analyses assessed robustness.
RESULTS: In the adjusted multiply imputed base-case analysis, mean incremental public-sector costs were £639 (95% CI £272 to £988) and mean incremental QALYs were 0.013 (95% CI -0.021 to 0.042), corresponding to a 13%-27% probability of cost-effectiveness at willingness-to-pay thresholds of £20,000-£30,000 per QALY. Complete-case analysis suggested lower costs and higher QALYs but with substantial uncertainty.
CONCLUSIONS: Over the 15-month trial horizon, the personalised parenting programme was associated with higher costs, a small and uncertain gain in QALYs, negative incremental net monetary benefit, and a low probability of being cost-effective at NICE-recommended willingness-to-pay thresholds.

BACKGROUND: Oral poliovirus vaccine (OPV) has been reported to cause vaccine-derived poliovirus and vaccine-associated paralytic poliomyelitis, and the limited global supply of conventional IPV has led many countries to rely on fractional-dose IPV regimens alongside OPV. The current study aims to assess the sIPV safety and immunogenicity when given concurrently with or in a staggered manner with routine immunization.
METHODS: A multi-country, multi-center, open-label, randomized controlled, extended phase III non-inferiority clinical trial was conducted with 1442 healthy infants aged 6-8 weeks from Bangladesh and Pakistan enrolled and randomized into four groups, i.e., co-administration group 1 (group C1), co-administration group 2 (group C2), staggered administration group 1 (group S1) and staggered administration group 2 (group S2). Antibody levels were determined using the collected sera for immunogenicity evaluation. The difference in seroconversion rates between the coadministration group and the staggered administration group is compared using the Cochran-Mantel-Haenszel χ2 (CMH-χ2) test, stratified by study site. Non-inferiority is concluded if the lower bound of the 95% confidence interval (CI) for the rate difference (coadministration group minus staggered administration group) is greater than -10%. The trial was registered prior to patient enrollment at clinicaltrials.gov (NCT05850364), and the protocol and statistical analysis plan are available at https://clinicaltrials.gov/study/NCT05850364. The trial is closed to new participants.
FINDINGS: The post-vaccination seroconversion rates for PV I were 90.3% (306/339) in group C1 and 87.0% (261/300) in group S1, for PV II, 91.7% (311/339) in group C1 and 91.3% (274/300) in group S1 and for PV III, 86.4% (293/339) in group C1 and 92.3% (277/300) in group S1. Among adverse reactions (ARs) reported within 7 days of vaccination, the incidence was similarly high in both the co-administration and staggered vaccination groups (92.8% vs. 95.5%).
INTERPRETATION: Our results demonstrated favorable safety and immunogenicity of co-administration of sIPV with other routine infant vaccines according to a 3-dose primary immunization schedule.

INTRODUCTION: We aimed to describe the rationale, design, and overall baseline characteristics of the trial evaluating the efficacy, safety, and tolerability of survodutide in Chinese adults with overweight or obesity (SYNCHRONIZE™-CN, NCT06214741).
METHODS: In this 76-week, multicenter, randomized, double-blind, placebo-controlled, phase 3 trial, Chinese participants were randomized 1:1:1 to once-weekly subcutaneous survodutide (3.6 mg or 4.8 mg) or placebo plus lifestyle intervention. Participants with either body mass index (BMI) ≥ 28 kg/m2 or BMI ≥ 24 kg/m2 and at least one obesity-related complication were eligible. The primary endpoints were the percentage change in body weight and achievement of body weight reduction ≥ 5% from baseline to week 52.
RESULTS: At baseline, participants (N = 306) had a mean age of 36.9 years, body weight 93.9 kg, waist circumference 105.6 cm, BMI 33.2 kg/m2, triglycerides 2.2 mmol/L. 49% were women. 72.9% had at least one obesity-related complication, with metabolic dysfunction‑associated steatotic liver disease (48.4%), dyslipidemia (42.2%), hypertension (27.8%), and type 2 diabetes mellitus (16.7%) being the most prevalent, followed by obstructive sleep apnea (4.6%) and cardiovascular diseases (4.2%). In total, 19.6% had prediabetes.
CONCLUSIONS: This trial was designed to provide a robust evaluation of efficacy and safety of survodutide for the treatment of obesity or overweight in Chinese adults.

BACKGROUND: Subthreshold depression is common, but whether lifetime trauma exposure and combined lifestyle are differentially associated with symptom transitions remains unclear.
METHODS: We analyzed a prospective community cohort in Shenzhen, China, of adults aged 18-65 years with a Patient Health Questionnaire-9 (PHQ-9) score ≥ 5 and no depressive disorder at baseline. Depressive symptom states (Normal, Mild, and Moderate/Severe) were assessed repeatedly over 36 months. Continuous-time multi-state Markov models estimated transition intensities, probabilities, and hazard ratios (HRs) for lifetime trauma exposure and a five-component combined lifestyle score, adjusting for demographic, socioeconomic, and health-related covariates.
RESULTS: Among 2361 participants (mean age, 37.30 years; 61.9% women), recovery transitions were more frequent than worsening transitions. The monthly Mild-to-Normal intensity was 0.131 (95% CI, 0.100-0.171), 2.47 times the Mild-to-Moderate/Severe intensity; Moderate/Severe-to-Mild was highest (0.205; 95% CI, 0.158-0.272). Lifetime trauma exposure was associated with lower Mild-to-Normal (HR, 0.54; 95% CI, 0.42-0.69) and Moderate/Severe-to-Mild rates (HR, 0.52; 95% CI, 0.41-0.65). Unfavorable lifestyle was associated with a lower Mild-to-Normal rate (HR, 0.70; 95% CI, 0.53-0.92) and a higher Mild-to-Moderate/Severe rate (HR, 1.60; 95% CI, 1.13-2.25). Those with both exposures had the lowest Mild-to-Normal rate (HR, 0.39; 95% CI, 0.26-0.59) and a higher Mild-to-Moderate/Severe rate (HR, 1.69; 95% CI, 1.05-2.73).
CONCLUSIONS: Lifetime trauma exposure was associated with lower recovery rates, whereas an unfavorable lifestyle was associated with lower recovery and higher worsening rates. These associations may inform trauma-informed assessment and lifestyle support for adults with subthreshold depression.

BACKGROUND AND AIMS: Artificial intelligence (AI)-assisted endoscopy represents a promising approach for lesion detection, yet frequent false-positive detections impair clinical utility by disrupting examinations and diminishing physician confidence. Linked-color imaging (LCI), an image-enhanced endoscopy technique that amplifies mucosal and vascular contrast, may address this limitation. This investigation evaluated whether LCI reduces false-positive AI detections compared with white-light imaging (WLI).
METHODS: This retrospective study analyzed consecutive AI-assisted upper endoscopies performed between March 2024 and June 2025. WLI and LCI were performed sequentially within the same endoscopic session in each patient. False-positive AI detections were compared between modalities using two computer-aided detection (CAD) versions. Propensity score adjustment was used as a sensitivity analysis for baseline differences between CAD Versions I and II.
RESULTS: Of 66 initially screened cases, 63 remained after excluding patients with prior gastric surgery. LCI reduced false-positive AI detections compared with WLI (median 2 vs. 5; p < 0.001). In CAD version-stratified sensitivity analyses, LCI reduced false-positive AI detections in both Version I (5 to 2; p = 0.01) and Version II (2 to 0; p = 0.03). This reduction remained consistent across atrophic grades. Both imaging modalities identified all gastric lesions, achieving 100% detection sensitivity.
CONCLUSIONS: LCI assessment performed after WLI observation yielded fewer false-positive CAD-EYE detections while maintaining lesion detection sensitivity. However, because the observation sequence was fixed, these findings should be interpreted cautiously and require confirmation in prospective or counterbalanced studies.

BACKGROUND: Transcutaneous auricular vagus nerve stimulation (taVNS) provides targeted modulation of the autonomic nervous system and descending pain pathways, exerting analgesic potential. However, high-quality evidence remains insufficient to determine whether taVNS can effectively replace opioids in sedation regimens for same-session bidirectional endoscopy while maintaining the quality of early postoperative recovery.
DISCUSSION: This study is a single-center, prospective, randomized, double-blind, placebo-controlled, three-arm non-inferiority trial. A total of 181 patients scheduled for painless same-session bidirectional endoscopy will be enrolled and randomly assigned using dynamic block randomization to one of three groups: Group S (sufentanil 0.1 µg/kg plus sham taVNS), Group T (normal saline plus active taVNS), and Group P (normal saline plus sham taVNS). All participants will receive ciprofol for sedation induction and maintenance. The primary outcome will be the quality of recovery at 24 h postoperatively, assessed using the 15-item Quality of Recovery scale (QoR-15), with a predefined non-inferiority margin (δ) of 6 points, which corresponds to the minimal clinically important difference of the QoR-15 scale. Secondary outcomes will include perioperative adverse events (pre-, intra-, and postoperative, including taVNS-related events), QoR-15 score at 1 h postoperatively, procedural and recovery efficiency indices, sedative dosage, and patient and endoscopist satisfaction scores. Blinding effectiveness will be assessed in all participants, and statistical analyses will follow the modified intention-to-treat principle.
CONCLUSION: This study protocol will rigorously assess the effectiveness and safety of taVNS as an alternative to opioid analgesics for sedation during same-session bidirectional endoscopy using, to our knowledge, the first three-arm design.Trial registration: Chinese Clinical Trial Registry (ChiCTR2600117962).
This study will provide the first systematic evaluation of the feasibility and efficacy of transcutaneous auricular vagus nerve stimulation (taVNS) as an opioid-sparing alternative to sufentanil for ciprofol-based sedation during same-session bidirectional endoscopy.A three-arm randomized design incorporating a prespecified trial-sensitivity analysis will be used to rigorously validate the effectiveness of the standard regimen, enhancing the interpretability and credibility of the non-inferiority conclusion.An “active placebo” taVNS stimulation model combined with an improved standardized questionnaire for blinding assessment will be employed to address the well-recognized limitations of inadequate blinding in taVNS research.

BACKGROUND: Hodgkin lymphoma (HL) survivors face an elevated long-term risk of developing second primary malignancies (SPMs), yet accurate prediction tools remain scarce. This study aimed to develop and internally validate a machine learning-based prediction model for SPM risk in HL survivors using a competing risk framework.
METHODS: We analysed 57,429 patients diagnosed with HL between 2006 and 2020 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were randomly divided into training (n = 40,201, 70%) and internal validation (n = 17,228, 30%) cohorts. A random survival forest (RSF) model was developed to predict SPM occurrence, with death without SPM treated as a competing event. Model performance was compared against the traditional Fine-Grey subdistribution hazard regression. Discrimination was assessed using time-dependent area under the receiver operating characteristic curve (AUC), and calibration was evaluated through calibration plots. Clinical utility was determined via decision curve analysis (DCA). SHapley Additive exPlanations (SHAP) analysis was employed to interpret the model.
RESULTS: During follow-up, 4,954 patients (8.6%) developed SPMs, while 9,750 (17.0%) died without SPM. The RSF model demonstrated superior discriminative ability compared to Fine-Grey regression across all time points: AUC at 3 years (0.721 vs. 0.549), 5 years (0.761 vs. 0.555), and 10 years (0.804 vs. 0.553). Calibration plots indicated good agreement between predicted and observed risks. DCA confirmed the RSF model provided greater net clinical benefit across a wide range of threshold probabilities. SHAP analysis identified age as the most influential predictor, followed by disease stage, radiotherapy status, race, sex, and chemotherapy.
CONCLUSIONS: The RSF-based machine learning model accurately predicts SPM risk in HL survivors within a competing risk framework, substantially outperforming traditional regression approaches. This interpretable prediction tool may facilitate personalised surveillance strategies and risk-adapted follow-up for HL survivors.

BACKGROUND: Antiseizure medications (ASMs) are the mainstay of epilepsy treatment; however, there is currently no reliable way to predict which medication will be most effective for an individual patient. Machine learning (ML) approaches are increasingly being explored to support personalized ASM selection, but successful implementation will depend on acceptance by both people with epilepsy and treating neurologists. Understanding factors influencing acceptability of ML in clinical decision-making is therefore critical to support engagement, trust, and adherence. The extended unified theory of acceptance and use of technology (UTAUT2) framework has previously been applied to evaluate acceptance of health care technologies, but its suitability for ML-supported ASM selection has not been established.
OBJECTIVE: The objective of this study was to co-design a UTAUT2-based questionnaire to measure ML technology acceptability that is suitable for use in a clinical trial.
METHODS: Adults living with epilepsy and prescribing neurologists were recruited using purposive sampling to participate in a co-design process evaluating the relevance, comprehensiveness, and clarity of the UTAUT2 framework in this clinical context. Participants completed an online survey that collected structured feedback on existing UTAUT2 constructs and identified additional factors influencing ML acceptance. Quantitative responses were analyzed descriptively, and qualitative responses were analyzed thematically to inform adaptation of the framework and development of a context-specific ML acceptability questionnaire.
RESULTS: A total of 32 participants completed the survey, including 22 (68.8%) adults living with epilepsy and 10 (31.2%) neurologists. While participants considered core UTAUT2 constructs relevant, qualitative feedback identified additional domains influencing ML acceptance, including emotional attitudes, perceived risks, knowledge enhancement, conflicts in shared decision-making, and contextual factors such as workplace policy and regulation. On the basis of this feedback, the ML acceptability questionnaire for ASM selection retained relevant UTAUT2 domains and incorporated additional constructs addressing trust and perceived risk. Other themes provided contextual insights for interpretation of ML acceptability and future implementation.
CONCLUSIONS: This study highlights the importance of co-design when adapting existing frameworks to the specific clinical context. The co-designed ML acceptance questionnaire for ASM selection developed in this study can be used to evaluate the acceptability of ML technology in the field of epilepsy, strengthening future trials and supporting ongoing technology development.

Radiofrequency hyperthermia (RFH) increases local tumor temperature and may enhance sensitivity to systemic therapies. We evaluated the association between adding RFH to first-line immune checkpoint inhibitor (ICI) plus chemotherapy and outcomes in patients with HER2-negative advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. This study adopted a single-center, retrospective, observational design. Patients treated between January 2021 and January 2024 were retrospectively enrolled and grouped by receipt of RFH (hyperthermia vs. non-hyperthermia). The primary endpoint was overall survival (OS); secondary endpoints were progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and safety. A 1:1 propensity score matching (PSM) analysis was performed. A total of 212 patients were included: 119 in the hyperthermia group and 93 in the non-hyperthermia group. In the overall cohort, RFH was associated with longer median PFS (10.17 vs. 7.06 months; HR = 0.70; p = .011) and median OS (19.31 vs. 14.98 months; HR = 0.71; p = .018). ORR did not differ significantly between groups (21.0% vs. 21.5%; p = .930), whereas DCR was higher with RFH (96.6% vs. 86.0%; p = .005). After PSM, 168 patients were matched; balance improved, but residual imbalance remained. Matched-cohort estimates remained directionally similar for PFS (9.72 vs. 7.09 months; HR = 0.67; p = .013) and OS (19.02 vs. 15.12 months; HR = 0.67; p = .015). Recorded grade ≥3 immune-related adverse events occurred in 5.0% and 4.3% of patients, respectively. RFH-related events were mainly transient local skin erythema and induration, and no RFH-related serious adverse events were recorded. RFH added to ICIs and chemotherapy was associated with longer PFS and OS, requiring confirmation in prospective randomized studies.

Complex agronomic traits in rice (Oryza sativa L.) are controlled by many genetic loci; however, dissection is often constrained in biparental mapping populations by limited recombination and narrow genetic diversity, and in diversity sets by spurious associations arising from cryptic relatedness. To overcome these limitations, we developed a nested association mapping (NAM) population of 422 recombinant inbred lines by crossing the upland tropical japonica IRAT109 with three genetically diverse japonica donors (Norin PL8, Langi, and RL11). Genotyping identified 4515 high‑quality polymorphic single nucleotide polymorphisms and revealed clear population stratification of the three subpopulations, with faster linkage disequilibrium decay (∼1.6 Mb) and broad allelic diversity, confirming that the genetic diversity of the NAM was sufficient for dissecting quantitative traits. Phenotyping under aerobic field conditions across two summer seasons for days to heading (DTH) and plant height (PH) recorded high heritabilities (0.96 for DTH; 0.92 for PH) and wide phenotypic ranges, confirming adequate phenotypic diversity for genomic analyses. Using multi-locus genome-wide association study (GWAS) models (Fixed and Random Model Circulating Probability Unification [FarmCPU] and Bayesian-Information and Linkage-Disequilibrium Iteratively Nested Keyway [BLINK]) alongside biparental linkage mapping, NAM identified nine additional loci undetected in biparental populations, improved mapping resolution by up to 6.3 Mb at specific loci, and revealed two quantitative trait loci (QTLs) co-localizing with known genes controlling DTH and PH, while linkage mapping captured family-specific allelic effects complementary to GWAS. Candidate genes were identified for the major‑effect QTLs qDTH6 (LOC_Os06g15370, LOC_Os06g16370, and LOC_Os06g16390) and qDTH7.1/qPH7.1 (LOC_Os07g15770), with sequence polymorphisms co‑segregating with donor alleles identified in GWAS, demonstrating the value of the IRAT109 NAM population for mapping and the discovery of loci underlying quantitative traits in rice.
Understanding the genes that control complex traits in rice is currently limited by traditional approaches. This study developed a novel population that maximizes genetic diversity to understand the genetic basis of flowering time and plant height. By combining DNA sequencing of the parents with genetic data from their offspring, it was demonstrated that the population contains sufficient genetic diversity to study quantitative traits in detail. Using genetic analysis methods, the study identified several regions of the genome affecting the studied traits, including both known genes and new candidate regions. This indicates that the design of the developed population was sufficient to pinpoint these regions much more precisely than traditional methods. Overall, this newly developed rice population is a valuable tool for discovering genes that influence key quantitative traits in rice.
