To assess the correlation between complete blood count (CBC)-derived inflammatory markers and sepsis-associated delirium (SAD) risk in older intensive care unit (ICU) patients.

Retrospective cohort study.

ICUs at Beth Israel Deaconess Medical Center (2008–2019), using the Medical Information Mart for Intensive Care IV V.3.0 database.

3412 critically ill patients aged ≥65 years with sepsis. Exclusion: repeated ICU admission, death/discharge within 24 hours, missing delirium assessment or pre-sepsis delirium from non-septic aetiologies. SAD was diagnosed by Confusion Assessment Method for the ICU.

Incidence of sepsis-associated delirium.

Among 3412 older sepsis patients, 2092 (61.3%) developed SAD. Significant differences in platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index, systemic inflammation response index, pan-immune-inflammation value and neutrophil-monocyte-to-lymphocyte ratio were observed between SAD and non-SAD groups (all p0.05). Receiver operating characteristic and random forest analyses demonstrated predictive utility; incorporating markers into a baseline model significantly improved discrimination, with MLR providing the largest gain (area under the curve (AUC)=0.716 vs 0.703; AUC=0.013, DeLong test, p

CBC-derived inflammatory markers, particularly MLR, are associated with increased SAD risk in older adults and enhance the performance of a clinical prediction model in this population. Further research is needed to better understand the pathophysiological mechanisms underlying these associations.

Patients’ sense of gain experience (PSGE) is the comprehensive feeling throughout the treatment process, which is a critical benchmark for evaluating comprehensive medical and health system reform in China. This study aims to assess the current status of PSGE in public hospitals and identify important associated factors, providing evidence-based recommendations for improving healthcare services.

This was a cross-sectional study conducted from October to November 2023.

A total of 14 public hospitals in Foshan, Guangdong Province, China.

There were 3223 responses, including 1592 from outpatients and 1631 from inpatients.

PSGE was assessed across five domains: time accessibility, service accessibility, cost affordability, patient participation and efficacy predictability. Participants were also asked to provide an overall rating of the PSGE.

The overall score for PSGE was 4.47±0.53 (mean±SD), with service accessibility receiving the highest score (4.68±0.50) and affordability the lowest (4.17±0.86). Secondary hospitals scored an overall PSGE of 4.55±0.50, while tertiary hospitals scored 4.42±0.54. Key factors associated with PSGE were overall satisfaction (β=0.164, p

This study found that patients reported a positive PSGE with service accessibility but reported a less positive PSGE with cost affordability. A tier-based disparity was evident, with secondary hospitals outperforming tertiary hospitals in overall PSGE outcome. Stronger PSGE was positively associated with higher scores in overall satisfaction, treatment satisfaction, satisfaction with medical reforms, patient loyalty and hospital reputation. Demographic and institutional factors, such as hospital level, patient type and household registration, were associated with the PSGE. Efforts can be focused on enhancing clinicians’ willingness and competence in discussing treatment costs during clinical encounters. It is essential for policymakers to address disparities in healthcare experiences among patient groups across hospital tiers to advance equitable, patient-centred systems.

Care (Education) and Treatment Reviews (C(E)TRs) are intended to reduce unnecessary psychiatric hospital admission and length of stay for people with intellectual disability and autistic people. The use and impact of C(E)TRs have not been systematically evaluated since their introduction in England in 2015. The aims of this study are to describe the demographic and clinical profiles of people who receive a community C(E)TR and to investigate their effects on admission, length of hospital stay and clinical and functional change.

We will conduct a retrospective cohort study using de-identified data from electronic health records derived from two large National Health Service mental health providers in London, England, including one replication site. Data will be extracted using the Clinical Record Interactive Search (CRIS) tool for all people with recorded intellectual disability and/or autism who received mental healthcare from 2015. We will identify community C(E)TR events using keyword searches. Community C(E)TRs will be examined in two ways: (1) In a community cohort, we will capture data in the 6-month periods before and after a community C(E)TR and compare this to a matched control group and (2) In a hospital cohort, we will compare groups who did and did not receive a community C(E)TR prior to their admission. We will describe the socio-demographic and clinical profiles of each group and their health service use, and compare C(E)TR and no C(E)TR groups using t-tests (or a non-parametric equivalent). The primary outcomes are admission to a psychiatric hospital (community cohort) and length of psychiatric hospital admission and clinical change (hospital cohort). Admission to psychiatric hospital will be estimated using propensity score weighting and difference-in-differences methods. Cox’s proportional hazard model will be used for length of hospital admission and repeated-measures analysis of variance (ANOVA) will be used to assess clinical change.

Use of CRIS to examine de-identified clinical data for research purposes has overarching ethical approval. This study has been granted local approval by the South London and Maudsley CRIS Oversight Committee. Findings will be disseminated in an open-access peer-reviewed academic publication, at conference presentations, and to service users and carers in accessible formats.

Colonoscopy is an essential procedure for the early diagnosis of colorectal conditions; however, over 60% of patients undergoing non-sedated colonoscopy report moderate to severe pain. This study aims to investigate the central analgesic mechanisms of transcutaneous electrical nerve stimulation based on wrist-ankle acupuncture theory (TENS-WAA). A multimodal approach combining electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) will be employed to assess pain-related brain activity, with artificial intelligence applied to model the relationship between objective neurophysiological signals and subjective pain experience.

This is a single-centre, randomised, double-blind, controlled trial involving 60 patients undergoing colonoscopy without anaesthesia. Participants will be randomly allocated (1:1) to either an electrical stimulation group receiving TENS-WAA or a sham stimulation group. EEG and fNIRS data will be acquired before, during and after the procedure. The primary outcome is the analysis of EEG-fNIRS signals to characterise cerebral responses associated with pain modulation. Secondary outcomes include patient-reported pain using the Visual Analogue Scale (VAS), total colonoscopy duration and the correlation between EEG-fNIRS indicators and VAS scores. A deep learning framework will be used to enhance pain prediction accuracy.

This study has received ethical approval from the Ethics Committee of Changhai Hospital, Shanghai (approval reference CHEC2025-006), and has been registered at ClinicalTrials.gov. Written informed consent will be obtained from all participants. Findings will be disseminated in peer-reviewed academic journals and at relevant scientific conferences, regardless of outcome, contributing to evidence-based, non-pharmacological pain management strategies.

Global urbanisation is intensifying alongside steadily expanding older adult populations. The resulting air pollution profoundly impacts human health by exacerbating diseases, particularly among vulnerable elderly groups. Evidence demonstrates that green spaces mitigate air pollutant effects on health. Recent studies indicate green space exposure benefits older adults physiologically, psychologically and socially. However, existing systematic reviews have not synthesised the health impacts on this demographic. Consequently, this protocol outlines a systematic review and meta-analysis to evaluate how green space exposure affects health outcomes in older adults.

This systematic review protocol adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. A comprehensive search strategy will be applied across: (1) electronic databases (eg, PubMed, Web of Science), (2) the National Institute for Health and Care Excellence and (3) the Guidelines International Network database. Grey literature will be searched via GreyNet International, covering records from each database’s inception to November 2024. The study will analyse associations between green space exposure and health outcomes in older adults. Two researchers will independently screen literature, extract data and assess risk of bias. Heterogeneity will be assessed with a focus on study design, exposure variables and outcome measures. If sufficient homogeneity exists, a meta-analysis will be undertaken; otherwise, a narrative synthesis will be performed.

This study requires no ethics approval because it uses publicly available data from published studies. The completed review will be published in a peer-reviewed journal and disseminated at relevant conferences.

PROSPERO (CRD42024619700).

Post-chronic pancreatitis (CP) diabetes mellitus (PPDM-C) is a distinct form of diabetes, in which complex pathogenesis hampers adequate glycaemic control. This study aimed to identify risk factors for poor glycaemic status in PPDM-C to guide clinical management.

Cross-sectional study.

Shanghai, China.

Between January 2018 and March 2023, 1677 patients with CP were enrolled in the CP database of the National Clinical Research Center. After application of strict exclusion criteria, 302 patients diagnosed with PPDM-C were included in the study.

The primary outcome was glycaemic control. The secondary outcomes were factors that affect glycaemic control among patients with PPDM-C.

This retrospective study was conducted in patients with PPDM-C. Poor glycaemic status was defined as a glycated haemoglobin A1c level of >7% at admission. Patients were stratified into those with and without diabetes treatment. Multivariate logistic regression was performed to identify risk factors. The area under the curve (AUC) analysis was used to evaluate the predictive efficacy of these risk factors.

A total of 302 patients with PPDM-C were analysed. Poor glycaemic status was observed in 72.6% (61/84) of patients without diabetes treatment and 52.8% (115/218) of those with diabetes treatment. For those without diabetes treatment, a history of acute pancreatitis (AP) attacks (OR: 4.838, p=0.014) and smoking (1–20 pack-years, OR: 4.418; >20 pack-years, OR: 9.989; p0.001). In patients with diabetes treatment, AP attack history (OR: 5.640, p20 pack-years, OR: 11.395; p

Patients with PPDM-C in China exhibited a high prevalence of poor glycaemic status. Smoking and a history of AP attacks were significantly associated with an increased risk of poor glycaemic control. The early identification of patients with PPDM-C at elevated risk of poor glycaemic control may facilitate timely and optimised management of glycaemia.

To investigate the nutritional status and its influencing factors in elderly patients aged 60 years and above with malignant tumours.

A retrospective observational study.

The First Affiliated Hospital of Chengdu Medical College, a tertiary care hospital in Chengdu, China.

A total of 450 elderly patients with cancer (aged ≥60 years) admitted between January 1, 2022, and January 1, 2023. Patients were selected based on their clinical records, excluding those with communication disorders, mental illness or incomplete data.

Nutritional status was assessed using the Patient-Generated Subjective Global Assessment (PG-SGA). Participants were categorised based on the presence or absence of malnutrition. Multivariate logistic regression was used to identify independent risk factors for malnutrition.

Of the 450 patients included, 63.7% were male and 36.3% female, with a median age of 69 years. The prevalence of severe malnutrition was 46.4%. Univariate analysis showed significant associations between malnutrition and factors such as older age (p

Malnutrition is highly prevalent in elderly patients with cancer and is significantly associated with age, BMI, albumin levels and self-care ability. Early identification and targeted nutritional interventions may improve outcomes and quality of life in this population.

Oliceridine is a novel μ-opioid receptor selective agonist that provides analgesia while reducing μ-receptor-mediated adverse effects such as postoperative nausea and vomiting (PONV). Evidence in abdominal surgery remains limited. This study aims to determine whether oliceridine reduces PONV and improves recovery in abdominal surgery.

This is a prospective, multicentre, two-arm, randomised trial. Participants aged 18–65 years, with American Society of Anesthesiologists physical status I–III and a body mass index of 18.5–23.9 kg/m², undergoing elective major abdominal surgery, will be eligible for inclusion. Gynaecological surgeries are excluded. All patients must require postoperative intravenous patient-controlled analgesia (PCIA) and give written consent. 494 participants will be randomised to oliceridine group or sufentanil group. The primary outcome is the incidence of PONV within 48 hours postsurgery. Secondary outcomes include vomiting frequency, nausea severity score, use of rescue antiemetics, resting numerical rating scale (NRS) pain score, Quality of Recovery-15 (QoR-15) score, time to first postoperative flatus, intensive care unit (ICU) length of stay (LOS), hospital LOS and PCIA metrics (effective attempts and total volume used). Safety outcomes include other opioid-related adverse effects (ORAEs) (eg, respiratory depression, pruritus, dizziness, headache), complications related to PONV (eg, electrolyte disturbances, wound dehiscence) and other perioperative complications.

This protocol was approved (Version V3.0, 2025-01-14) by the Ethics Committee of Changhai Hospital (CHEC-2025–069), the Shanghai Public Health Clinical Centre (2025-S024-01) and the Wusong Central Hospital of Baoshan District, Shanghai (2025-17-01). It complies with the Declaration of Helsinki. Results will be shared via conferences and peer-reviewed journals.

Video-assisted thoracoscopic surgery (VATS) has become the predominant method for lung cancer diagnosis and resection, with over 80% adoption in relevant surgeries. With technological advancements, uniportal VATS is now widely employed. However, it still poses a significant risk of moderate to severe acute postoperative pain, potentially leading to chronic post-thoracotomy pain syndrome (PTPS). Therefore, effective postoperative analgesia is crucial. Regional block techniques have gradually gained wide attention. Specifically, paravertebral block (PVB) has been considered the ‘gold standard’ for thoracic analgesia, but its application involves risks due to the challenging anatomy. The erector spinae plane block (ESPB) and intertransverse process block (ITPB) have emerged as alternatives. ESPB showed non-inferiority to PVB in pain management and recovery quality. However, the mechanism of ESPB and its consistency in providing analgesia are not fully understood. ITPB, targeting the ‘posterior space of the superior costotransverse ligament’, offers theoretical advantages in drug diffusion due to its closer proximity to the paravertebral space than ESPB. Despite these advancements, there is a lack of randomised controlled trials (RCTs) assessing the comparative efficacy of continuous ESPB and ITPB. This study aims to address these gaps by comparing the analgesic effects and recovery quality of continuous ESPB and ITPB in patients undergoing single-port VATS.

A double-blind RCT will be conducted, enrolling 96 patients electively undergoing single-port thoracoscopic surgery, randomly assigned to either the experimental group (ITPB group) or the control group (ESPB group). After routine surgery, block intervention and continuous pump catheterisation will be performed. The primary assessment will be the numeric rating scale (NRS) scores at 24 hours. Secondary outcomes include NRS at other time points, block effectiveness, Quality of Recovery-15 scores and chronic pain-related scores. Evaluations will be conducted at 0, 2, 6, 12, 24 and 48 hours. Additional assessment indicators include time to first self-administration of pulse analgesia pump, number of self-administrations within 48 hours, use of non-steroidal anti-inflammatory drugs and opioids postoperatively, Comprehensive Complication Index (CCI) score, length of hospital stay, incidence of adverse events and complications, patient satisfaction score and assessment of PTPS incidence at 3 months postoperatively using the Brief Pain Inventory short form and the Short-Form McGill Pain Questionnaire.

The study was reviewed and approved by the Medical Ethics Committee of the Fifth Affiliated Hospital of Sun Yat-sen University (No. K44-1, 2024). The results of the study will be submitted for publication in a peer-reviewed journal with online accessibility.

Until now, there has still been a lack of sufficient evidence on patient-reported outcomes (PROs) measured by the EuroQol-5 Dimension (EQ-5D) in patients with systemic lupus erythematosus (SLE) in China. This study aims to comprehensively assess EQ-5D outcomes and influencing factors in Chinese patients with SLE.

A multicentre, cross-sectional study based on the Chinese Systemic Lupus Erythematosus Treatment and Research Group registry.

101 hospitals across 27 provinces of China.

1336 patients with SLE.

The information on EQ-5D was collected via an online questionnaire. Medical records were obtained from the Chinese Rheumatology Data Centre (CRDC). Clinical influencing factors related to the reported health problems were identified using multivariate logistic regression. Then, each health state was converted into a health utility score based on the Chinese 2014 tariff. Given the ceiling effects, Tobit regression models were used to analyse the factors influencing health utility scores.

A total of 1336 patients with SLE were included. Of them, 626 patients (46.9%) reported health problems using EQ-5D. The proportions of patients reporting problems in mobility, self-care, usual activities, pain/discomfort and anxiety/depression were 12.80%, 5.24%, 14.90%, 27.47% and 30.46%, respectively. The mean utility score was 0.89 (SD: 0.15), and the mean Visual Analogue Scale (VAS) score was 76.80 (SD: 16.54). There was a statistically significant correlation (r=0.503, p

EQ-5D may be a useful, preference-based PRO measure for SLE and could potentially be integrated into routine clinical monitoring of patients with SLE and applied in economic evaluations in the future.

Postoperative pain is particularly pronounced in spinal surgery. Inadequate management of acute postoperative pain not only reduces patient satisfaction and delays recovery but also increases the risk of developing chronic pain. Local infiltration analgesia (LIA) is a widely used technique for perioperative pain management. However, even with the use of long-acting local anaesthetics, such as ropivacaine, postoperative analgesia often remains insufficient. Preliminary evidence suggests that combining diprospan, a mixture of betamethasone disodium phosphate and betamethasone dipropionate, with ropivacaine can significantly reduce analgesic requirements in the immediate postoperative period. However, concerns about steroid-related complications, including hyperglycaemia and surgical site infections, highlight the need to identify the minimum diprospan concentration to achieve a balance between efficacy and safety. This randomised, controlled, evaluator-blinded trial aims to investigate the dose-response relationship of diprospan as an adjunct to ropivacaine for LIA in spinal surgery to determine the minimum effective dose for effective and safe pain management.

This is a single-centre, randomised, evaluator-blinded, controlled, dose-mapping study in which subjects will be randomised in a 1:1:1:1:1 ratio to the control group or to receive diprospan at concentrations of 0.003%, 0.006%, 0.009% or 0.012%. Patients will receive either 0.5% ropivacaine alone or a corresponding dose of diprospan combined with 0.5% ropivacaine for LIA. All participants will be followed for a duration of 3 months. The primary outcome measure will be cumulative sufentanil consumption within the first 48 hours postsurgery. Secondary outcomes will include additional assessments of analgesia, steroid-related adverse events and other complications within the 3-month follow-up period.

This study protocol was approved by the Institutional Review Board of Beijing Tiantan Hospital (KY2024-365-02-1). Written informed consent will be obtained from all participants. The results will be submitted for publication in a peer-reviewed journal.

Self-harm and suicide are common among prison inmates, but less is known about these phenomena in those with psychosis.

The aim of this study was to examine self-harm behaviour in New South Wales (NSW) prisons in Australia among inmates diagnosed with psychosis. This study also examined self-harm-related alerts applied by Corrective Services to assist staff with the management of the security and well-being of inmates.

A retrospective case-control data-linkage study was conducted using administrative data collections in NSW, Australia.

The study included all individuals diagnosed with psychosis and incarcerated between 2001 and 2020 in NSW as cases and an age and sex matched control group with no such diagnosis with a record of incarceration in the same time period.

The primary outcome measure was self-harm among the cases and controls. The secondary outcome measure was the application of alerts by Corrective Services in relation to self-harm incidents.

Multivariate regression analysis was used to examine predictors of self-harm in prison. Prisoners with psychosis (n=14 900) were more likely to self-harm than controls (n=2713), with 15.0% versus 3.6% engaging in self-harm (highest odds of self-harm observed in those with schizophrenia and related psychoses, aOR=4.84, 95% CI: 3.93 to 5.98). Those of Aboriginal heritage had an increased risk of self-harm (aOR=1.58, 95% CI: 1.43 to 1.75). Factors associated with a lower risk of self-harm were male sex and older age (≥25 years) at the time of their first incarceration. 35.6% of those released from prison with a prior psychosis diagnosis had at least one alert applied during incarceration compared with 10.1% of prisoners without a diagnosis of psychosis. Overall, 35 individuals with psychosis and 1 individual from the control group died while in prison between 2001 and 2020. 17 prison suicides were recorded from the study population; all occurred in the psychosis group.

Given the heightened risk of self-harm in those with histories of psychosis, consideration should be given to sharing mental health information between agencies to improve the care and management of this group during incarceration. Prison alerts may be a useful tool to help staff manage inmates’ well-being if used appropriately.

Coronary artery bypass grafting (CABG) is a standard treatment for coronary artery disease, particularly in patients with multivessel disease. Connecting the saphenous vein graft (SVG) to the right internal mammary artery (RIMA) instead of the aorta has been proposed as an alternative approach to minimise aortic manipulation and potentially improve graft patency. This study aims to determine whether the RIMA-SVG technique is non-inferior to the conventional Aorta (Ao)-SVG approach in terms of 1-year graft patency, while also comparing perioperative complications and short-term clinical outcomes.

This non-inferiority, single-centre, prospective, double-blind, randomised clinical trial will enrol 300 patients undergoing CABG. Participants will be randomised into two surgical groups (RIMA-SVG vs Ao-SVG). The primary outcome is the 1-year SVG patency rate, assessed using coronary CT angiography. Secondary outcomes include perioperative complications, all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCE), and surgical site infections occurring during hospitalisation and up to 1 year postoperatively. Randomisation will be computer-generated, and all procedures will be performed by experienced surgeons. Patients will be followed up 12 months post-surgery. Non-inferiority will be established if the upper bound of the one-sided 97.5% CI for the difference in graft occlusion rates is less than the prespecified non-inferiority margin of 10%.

This study has been approved by the Ethics Committee of the Second Hospital of Jilin University (No. 460) and registered at ClinicalTrials.gov (NCT06787651). All participants will provide written informed consent before enrolment. To ensure data integrity and minimise bias, randomisation details will be concealed from researchers until surgery, and data analysts will remain blinded to group assignments. The findings will be disseminated through academic journals and conference presentations to promote knowledge sharing and clinical application in the field of cardiovascular surgery.

Artificial intelligence (AI) has the potential to revolutionise healthcare delivery, particularly in the domain of emergency medicine. With the rise of telemedicine and virtual care, AI-powered tools could assist in triage, diagnosis and treatment recommendations for patients seeking emergency care remotely. This systematic review aims to synthesise the current state of research on AI applications in virtual emergency care, identify key challenges and opportunities and provide recommendations for future research and implementation.

We will conduct a comprehensive search of multiple electronic databases (PubMed, Web of Science, Embase, CINAHL, MEDLINE, The Cochrane Library, Scopus) from each database’s inception to March 2025. The search will include terms related to AI, machine learning, deep learning, virtual care, telemedicine and emergency medicine. We will include original research articles, conference proceedings and preprints that describe the development, validation or implementation of AI models for virtual emergency care. Two reviewers will independently screen titles and abstracts, review full texts, extract data and assess risk of bias using the PROBAST (Prediction model Risk Of Bias ASsessment Tool) tool for prediction model studies, Cochrane Risk-of-Bias tool for randomised trials for randomised trials and Risk Of Bias In Non-randomised Studies of Interventions for non-randomised studies. Data synthesis will involve a narrative review of included studies, summarising key findings, methodological approaches and implications for practice and research. The results will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

No ethical approval is required for this systematic review as it will use only published data. The findings will be disseminated through publication in a peer-reviewed journal, presentations at relevant conferences and engagement with clinicians, health system leaders, policymakers and researchers. This review will provide a timely and comprehensive overview of the applications of AI in virtual emergency care to inform evidence-based guidelines, policies and practices for leveraging these technologies to enhance access, quality and efficiency of emergency care delivery.

Systemic therapies for advanced gastric cancer (GC), including chemotherapy, targeted therapy and immunotherapy, have evolved significantly in the past few years. The combination of immune checkpoint inhibitors (ICIs) and chemotherapy has become the standard first-line (1L) treatment for advanced gastric or gastro-oesophageal junction (G/GEJ) cancer, although there remains a need for improvement in efficacy. Fruquintinib, an oral and highly selective vascular endothelial growth factor receptor inhibitor, has shown a synergistic antitumour effect when paired with ICI or chemotherapy. Moreover, it has demonstrated a tolerable safety profile and high potential for synergy with chemotherapy or immunotherapy, suggesting that a combination of fruquintinib, sintilimab and oxaliplatin+capecitabine (CAPEOX) can be a promising treatment for locally advanced G/GEJ cancer. This phase 1b/2 study aims to investigate the safety and efficacy of the combination of fruquintinib, sintilimab and CAPEOX regimen as a 1L combination therapy for unresectable advanced or metastatic G/GEJ cancer.

The FUNCTION trial (NCT06329973) is a single-arm, prospective, multicentre, phase Ib/II clinical trial that will consist of a dose escalation phase and an expansion phase. The study is planned to be conducted at 16 public hospitals. A total of 70 participants will be enrolled, comprising nine in the dose escalation phase and 61 in the expansion phase. The dosing regimen during the dose escalation phase will include three different doses of fruquintinib (3 mg, 4 mg and 5 mg, per oral, once per day days 1–14) + sintilimab, 200 mg, intravenous, day 1 +oxaliplatin 130 mg/m², day 1, intravenous, + capecitabine 800 mg/m², per oral, twice daily, days 1–14, every 21 days. The recommended phase 2 dose (RP2D) and maximum tolerated dose will be determined in the escalation phase, and the RP2D will be used in the expansion phase. The primary endpoints will be the maximum tolerated dose and objective response rate; the secondary endpoints will include OS, progression-free survival, disease control rate, duration of response, surgical conversion rate and adverse events and identification of molecular biomarkers for efficacy. The results from this study will provide evidence for expanding the clinical applications of fruquintinib plus sintilimab and CAPEOX as a 1L combination therapy in metastatic or non-resectable, locally advanced G/GEJ cancer and lay the foundation for future large-scale clinical investigations.

This study will be conducted in full compliance with the ICH (The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, ICH) GCP (Good Clinical Practice, GCP) guidelines, the rules of the Declaration of Helsinki and ICH E2A (Clinical Safety Data Management: Definitions and Standards for Expedited Reporting) Guidelines . The study protocol has received approval from the Henan Cancer Hospital ethical committee (Approval No. 2023-237-002). Written informed consent will be obtained from all patients prior to enrolment. For patients who have the mental capacity for informed consent, their consent for participation will be sought and will not be overridden by their family members. For patients who have impaired cognition, informed consent will be sought from their legally acceptable representative. On completion of the analyses, the study findings will be disseminated locally and internationally through manuscript publications in peer-reviewed journals and conference presentations.

To predict the outcome of patients with traumatic brain injury (TBI) using the optic nerve sheath diameter (ONSD) and the central venous minus arterial CO₂ pressure to arterial minus central venous O₂ content ratio (Pcv-aCO₂/Ca-cvO₂) in prehospital settings.

A prospective cohort study was conducted in China.

The study was conducted from October 2023 to October 2024, enrolling patients diagnosed with TBI. Participants presenting a Glasgow Coma Scale (GCS) 2/Ca-cvO₂: Group A Pcv-aCO₂/Ca-cvO₂ >1.8 mm Hg/mL and ONSD >5.6 mm; Group B: Pcv-aCO₂/Ca-cvO₂ >1.8 mm Hg/mL and ONSD ≤5.6 mm; Group C: Pcv-aCO₂/Ca-cvO₂ ≤1.8 mm Hg/mL and ONSD >5.6 mm; and Group D: Pcv-aCO₂/Ca-cvO₂ ≤1.8 mm Hg/mL and ONSD ≤5.6 mm.

30-day mortality, functional neurological recovery at discharge (measured by Glasgow Outcome Scale (GOS)), and length of intensive care unit (ICU) stay were compared between the 4 groups.

Our findings show that Group D had the lowest 30-day mortality, the shortest ICU stay and the highest good recovery at discharge (GOS score) among the four groups. Survival curves illustrated a decrease in 30-day mortality in group C patients after mannitol administration compared with patients who did not receive mannitol administration. The area under the receiver operating characteristic curve for Pcv-aCO₂/Ca-cvO₂ combined with ONSD (0.907 (95% CI 0.843 to 0.941)) was higher than those for ONSD (0.851 (95% CI 0.791 to 0.911)) alone, Pcv-aCO₂/Ca-cvO₂ (0.814 (95% CI 0.744 to 0.873)) alone or initial GCS (0.823 (95% CI 0.763 to 0.889)). Calibration plots demonstrated a strong alignment between observed and predicted probabilities for ONSD, Pcv-aCO₂/Ca-cvO₂, the combination of ONSD and Pcv-aCO₂/Ca-cvO₂, and initial GCS.

ONSD combined with Pcv-aCO₂/Ca-cvO₂ is a relatively novel method for predicting the outcome in TBI patients, especially in a prehospital setting. This dual approach may improve the prediction of early prognosis and guide osmotherapy treatment in patients with TBI.

This qualitative study aimed to address the following central research question: what are the key factors and behavioural trajectories influencing delayed medical care-seeking among participants with breast cancer-related lymphoedema (BCRL), and how do these factors operate across the stages of symptom perception, alertness and decision-making?

This qualitative study employed a phenomenological approach, with semistructured interviews conducted to explore participants' experiences.

A tertiary hospital located in North China.

18 patients with BCRL were recruited through purposive maximum variation sampling and interviewed in person between January and June 2023.

10 themes emerged and were categorised into three stages: (1) the perception stage (lack of disease knowledge, risk underestimation and symptom avoidance); (2) the alertness stage (failed self-management, negative coping and exposure to misinformation) and (3) the decision-making stage (financial burden, limited healthcare access, insufficient social support and fatalism). The average delay was 10.2 months, with prolonged delays (>12 months) linked to severe lymphoedema progression.

Delayed care seeking in BCRL is a multifactorial behavioural trajectory shaped by knowledge gaps, systemic barriers and psychosocial factors. Clinicians should prioritise early patient education and context-sensitive interventions to mitigate delays.
