The Relationship Between Chinese Nurses' Subjective Age and Career Satisfaction: The Mediating Role of Role Breadth Self‐Efficacy

ABSTRACT

Aim(s)

To assess career satisfaction among Chinese nurses, explore influencing factors, and examine the mediating role of role breadth self-efficacy (RBSE) in the relationship between subjective age and career satisfaction.

Design

A multi-centre, cross-sectional study.

Methods

Between June and October 2024, 2033 questionnaires were distributed to nurses across seven geographic regions in China, collecting data on demographics, subjective age, RBSE, and career satisfaction. Descriptive statistics, Pearson correlation analysis, multiple linear stepwise regression, and path analysis were used to identify determinants of career satisfaction and test the mediating effect of RBSE.

Results

The effective response rate was 97%. Chinese nurses reported moderate-to-high career satisfaction, younger subjective age relative to chronological age, and moderate RBSE levels. Multivariate linear regression analysis identified education level, work institution, salary, weekly working hours, subjective age, and RBSE as significant predictors of career satisfaction. Path analysis revealed a significant negative association between subjective age and career satisfaction (β = −0.23, p < 0.001), which was partially mediated by RBSE (indirect effect = −0.11, 95% CI: −0.18 to −0.05).

Conclusions

The career satisfaction of Chinese nurses is at a moderately high level; the influencing factors include the intensity of nursing work and salary levels. There is a certain difference between the subjective age and the chronological age of Chinese nurses. RBSE partly mediates the relationship between subjective age and career satisfaction.

Implications for the Profession and/or Patent Care

Valuing the breadth of nurses' roles, self-efficacy, and subjective age may help improve job satisfaction.

Impact

What problem did the study address?: This study elucidates the present level of career satisfaction among nurses in China and the variables affecting it. What were the main findings?: The subjective age of Chinese nurses influences career satisfaction, with RBSE partly mediating the connection between subjective age and career satisfaction. Where and on whom will the research have an impact?: This study presents novel variables of subjective age and RBSE in the investigation of factors influencing career satisfaction among Chinese nurses, offering new avenues for enhancing career satisfaction in this demographic in the future.

Reporting Method

We adhered to STROBE guidelines for cross-sectional research.

Targeting vascular dementia: Molecular docking and dynamics of natural ligands against neuroprotective proteins

by Zhizhong Wang, Sen Xu, Ailong Lin, Chunxian Wei, Zhiyong Li, Yingchun Chen, Bizhou Bie, Ling Liu

Vascular dementia (VaD), a neurodegenerative disease driven by vascular pathology, requires multi-targeted therapeutic strategies. This study employs an integrated in silico approach to evaluate the neuroprotective potential of natural ligands against key proteins implicated in VaD pathogenesis. Using molecular docking and normal mode analysis (NMA), four natural compounds (Galangin, Resveratrol, Curcumin, and Licocumarone) were assessed for their binding affinity and structural influence on six target proteins: APLP1, APOE, CLDN5, SOD1, MMP9, and MTHFR. Docking analysis revealed that galangin exhibited the highest binding affinity to APLP1 (−8.5 kcal/mol), resveratrol to MTHFR (−8.1 kcal/mol), and curcumin showed dual efficacy toward APOE (−7.2 kcal/mol) and MMP9 (−8.0 kcal/mol). Licocumarone demonstrated notable stabilization of CLDN5 and SOD1. The NMA results indicated ligand-induced stabilization of protein cores and enhanced flexibility in loop regions, which may impact amyloid aggregation, oxidative stress, and blood-brain barrier integrity. Pathway enrichment using the KEGG and Reactome databases identified significant involvement of the IL-17 and TNF signaling pathways, along with leukocyte transendothelial migration, linking inflammation with vascular dysfunction. APOE emerged as a central node within the protein-protein interaction network, highlighting its regulatory importance. This study highlights the therapeutic relevance of natural ligands as cost-effective modulators of multiple VaD-associated pathways. The combined use of molecular docking, protein dynamics, and enrichment analyses provides a comprehensive computational framework for early-stage drug discovery. These findings warrant further experimental validation to advance the development of targeted, mechanism-driven interventions for vascular dementia.

A blueprint of synergistic effect in Crataegus pinnatifida and obesity-related gut microbiota against obesity via systems biology concept

by Jinghui Xie, Haofang Guan, Maohui Liu, Weijun Ding

Background

Current obesity treatments include behavioral interventions, pharmacotherapy and surgery. Recently, the combination of ‘medicinal food’ products such as the plant Crataegus pinnatifida and its interaction with the gut microbiota has shown promise as an alternative therapeutic strategy to treat obesity.

Methods

We obtained secondary metabolites (SMs) of obesity-related gut microbiota and Crataegus pinnatifida from gutMGene database and NAPSS database. bioinformatics analysis was used to elucidate key target and signaling pathways, whereas molecular docking (MD), molecular dynamics simulation and quantum chemical calculations identified crucial SMs involved in these pathways. The toxicity and physicochemical properties of these SMs were also assessed.

Results

Phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), a key mediator in the phosphoinositide 3-kinase (PI3K)/ Protein Kinase B (Akt) pathway that is crucial for regulating insulin signaling and adipogenesis, emerged as the central hub within the PPI network. Strong binders to PIK3R1 were predicted to be quercetin, kaempferol and naringenin chalcone, suggesting their potential as therapeutic agents to treat obesity.

Conclusion

The synergistic combination of Crataegus pinnatifida and the obesity-related gut microbiota holds promise as a novel therapeutic strategy for obesity by targeting PIK3R1 and modulating the PI3K/Akt signaling pathway. Further experimental validation is necessary to confirm these findings.

Correlation between complete blood count-derived inflammatory markers and sepsis-associated delirium in older patients: a retrospective analysis of the MIMIC-IV database

Por: Wang · L. · Tian · Z. · Zuo · L. · He · Y. · Liu · Y. · Liu · H.
Objectives

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.

Design

Retrospective cohort study.

Setting

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

Participants

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.

Primary outcome measure

Incidence of sepsis-associated delirium.

Results

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

Conclusion

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.

Burnout and job stress in healthcare professionals: a single-centre cross-sectional study in an East China tertiary hospital after COVID-19 policy adjustment

Por: Ji · W. · Liu · Y. · Sun · Q. · Wu · D. · Liu · T. · Sun · P.
Objectives

To examine the relationship between job stress and job burnout among healthcare professionals (HPs) in a tertiary hospital in East China following the adjusted COVID-19 prevention policies and to explore the effects of demographic and work environment factors on burnout and its subtypes (emotional exhaustion (EE), depersonalisation (DP), personal accomplishment (PA)).

Design

Cross-sectional, using a questionnaire-based survey method.

Setting

A tertiary hospital located in Qingdao, East China.

Participants

A total of 434 HPs were included, with 138 men (31.8%) and 296 women (68.2%); the mean age was 35.05±7.96 years. Participants included physicians (37.1%), clinical nurses (49.5%), clinical pharmacists (3.9%), medical technicians (5.1%) and administrative staff (4.4%). Demographic factors (age, sex, marital status, education level, professional title, length of employment, income) and work-related factors (weekly working hours, sleep duration) were collected.

Interventions

No specific interventions were implemented; this was an observational study focusing on the burnout assessment and associated factors.

Primary and secondary outcome measures

Primary outcomes: burnout levels assessed via the Chinese version of the Maslach Burnout Inventory—Human Services Survey (MBI-HSS), including three subscales: EE (9 items), DP (5 items) and PA (8 items). Severe burnout was defined as meeting ‘high-level’ criteria for all three subscales (EE ≥27, DP ≥10, PA ≤33).

Secondary outcomes: demographic (sex, professional role, length of employment) and work-related (weekly working hours, daily sleep duration) factors associated with burnout.

Results

Among 434 HPs, 74 (17.1%) experienced severe burnout. The median scores of MBI-HSS subscales were 17 (IQR: 9–27) for EE, 3 (IQR: 0–7) for DP and 37 (IQR: 27.75–43) for PA. Multivariate logistic regression showed that: nurses had a higher risk of high EE than physicians (OR=2.86, 95% CI: 1.32 to 6.21, p40 hours (OR=2.30, 95% CI: 1.32 to 3.99, p

Conclusions

A high prevalence of severe burnout (17.1%) was observed among HPs after COVID-19 policy adjustment. Key risk factors include being a nurse, long working hours (>40 hours/week), short sleep duration (

Comparison of ultrasound-guided continuous intertransverse process block and continuous erector spinae plane block for postoperative analgesia after uniportal video-assisted thoracoscopic surgery: protocol for a double-blind, prospective, randomised contr

Por: Lei · C. · Liu · D. · Li · Q. · Chen · Y. · Chen · H. · Zhong · H. · Wang · Y.
Introduction

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.

Methods and analysis

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.

Ethics and dissemination

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.

Ambulatory foetal ECG monitoring in low and high-risk pregnancies (AMBER2): a prospective cohort study protocol

Por: Pegorie · C. · Liu · B. · Thilaganathan · B. · Bhide · A.
Introduction

Measuring foetal heart rate (FHR) is critical for assessing foetal well-being, and traditional cardiotocography (CTG), though effective, has limitations such as cost, accessibility and observer bias. Newer non-invasive foetal ECG (NIFECG) devices offer more precise, reliable metrics for FHR variability and could enable remote monitoring, potentially improving early detection of foetal complications like hypoxia and stillbirth.

Methods and analysis

This is a single-centre prospective cohort study taking place in a tertiary maternity unit in the UK. Women with a singleton pregnancy over 26+0 weeks will be approached for participation in the control, foetal growth restriction (FGR) or diabetic groups. The NIFECG home monitoring schedule is 60 min daily for 7 days in the control group, daily from diagnosis until delivery for the FGR group, and daily from 36 weeks until delivery in the Insulin-dependent diabetic group. Longitudinal FHR raw ECG signals will be collected from participants across different gestational age ranges. Reference standards for FHR variability using metrics such as short-term variation, phase-rectified signal averaging acceleration and deceleration capacity will be established. The study will also aim to explore differences in FHR variability in FGR cases against controls and propose safety thresholds to guide decision-making for delivery.

Ethics and dissemination

Approvals have been obtained from the London Stanmore Research Ethics Committee and from the Medicines and Healthcare Regulatory Agency. The results will be published in peer-reviewed journals, presented at conferences and used by the commercial sponsor to pursue European Conformity regulatory compliance marking and future clinical studies.

RIMA-SVG versus Ao-SVG in coronary artery bypass grafting: protocol for a prospective, randomised, double-blind, non-inferiority and single-centre trial

Por: Wei · R. · Huang · M. · Jiang · N. · zhang · R. · He · T. · Zhu · C. · Wang · W. · Piao · H. · Yu · S. · Zhu · Z. · Wang · T. · Liu · K.
Introduction

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.

Methods and analysis

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%.

Ethics and dissemination

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.

Trial registration number

NCT06787651.

Relationship between anion gap and 28-day all-cause mortality in patients with acute pulmonary edema: A retrospective analysis of the MIMIC-IV database

by Ping Guo, Yuwen Liu, Xiaomi Huang, Yanfang Zeng, Zhonglan Cai, Guang Tu

Background

Acute pulmonary edema is a severe clinical condition with high mortality. The anion gap, reflecting metabolic acid-base disturbances, is often elevated in critically ill patients. However, its relationship with outcomes in acute pulmonary edema remains unclear.

Objective

To explore the association between admission anion gap levels and 28-day all-cause mortality in patients with acute pulmonary edema.

Methods

This retrospective cohort study utilized data from the MIMIC-IV database (2008–2019) and included adult patients with acute pulmonary edema. Patients were categorized into quartiles based on anion gap levels. Cox regression models analyzed the relationship between anion gap and mortality, with restricted cubic spline (RCS) curves, Kaplan-Meier analysis, and subgroup analyses.

Results

A total of 1094 patients were included. Univariate Cox regression showed a positive correlation between anion gap levels and 28-day mortality (HR = 1.13, 95%CI: 1.09–1.17, P P P  Conclusion

Admission anion gap levels predict 28-day all-cause mortality in acute pulmonary edema patients, particularly in younger patients and those without renal disease. Clinically, anion gap monitoring should be emphasized, and individualized prognostic and treatment strategies should be developed with factors like age and renal status to improve outcomes.

Enhanced Bézier curve-based trajectory planning for high-altitude autonomous trucks

by Du Chigan, Jianbei Liu, Yang Zhao, Jianyou Zhao

Highway freight transport is the backbone of Tibet’s logistics network, accounting for 76.4% of regional freight movement (Tibet Bureau of Statistics, 2024). Challenging alpine road conditions—characterized by steep grades, sharp curves, and narrow lanes—combine with the substantial dimensions of heavy trucks to create significant operational difficulties. Autonomous truck development offers a potential solution; however, their trajectory planning algorithms exhibit limitations in high-altitude environments. To address these challenges, we propose a novel trajectory planning method using quartic Bézier curves. These 4th-order parametric curves provide G² continuity. Our approach integrates speed profiles into a three-dimensional curve representation and employs a two-phase optimization process to ensure safety and efficiency. Simulation results demonstrate the method’s effectiveness in maintaining truck stability while enabling responsive maneuvering under Tibet’s demanding road conditions.

Single-arm, open-label, multicentre phase 1b/2 study to evaluate the safety and efficacy of fruquintinib combined with sintilimab and CAPEOX as a first-line treatment for advanced gastric or gastroesophageal junction adenocarcinoma (FUNCTION study): a stu

Por: Chen · B. · Zhao · J. · Lv · H. · Xu · W. · Wang · J. · Nie · C. · He · Y. · Zhang · B. · Huang · J. · Liu · Y. · Ma · F. · Zhang · H. · Guo · L. · Liu · Y. · Li · P. · Chen · X. · Chen · X.
Introduction

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.

Methods and analysis

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.

Ethics and dissemination

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.

Knowledge, attitude and practice regarding scars in patients who had orthopaedic surgery: a cross-sectional study in China

Por: Kong · D. · Sun · M. · Li · K. · Huang · Y. · Liu · J.
Objectives

This study aims to describe the knowledge, attitude and practice (KAP) regarding surgical scars among patients who had postorthopaedic surgery, and to explore correlations between these factors.

Design

A multicentre, cross-sectional, observational study.

Setting

Conducted across multiple secondary/tertiary care hospitals between July and September 2024.

Participants

Of 816 enrolled participants undergoing orthopaedic surgery, 54.5% were male, 43.6% were aged 31–45 years, 73.9% were urban dwellers, 31.2% had a bachelor’s degree and 65.4% were married.

Interventions

None (questionnaire-based assessment).

Outcome measures

Primary outcomes were KAP scores (knowledge: 0–22; attitude: 9–45 and practice: 7–35), analysed via correlation and regression.

Results

Mean scores: knowledge (12.5±6.9), attitude (27.6±3.3) and practice (28.2±6.5). Knowledge was negatively correlated with attitude (r=–0.24, p

Conclusions

Patients who had postorthopaedic surgery demonstrated poor scar-related knowledge and negative attitudes but proactive practices. Greater knowledge correlated with better practice, suggesting targeted education could optimise scar management. Further research should explore causal relationships and the efficacy of interventions.

Risk Prediction Models for Enteral Nutrition Aspiration in Adult Inpatients: A Systematic Review and Critical Appraisal

ABSTRACT

Objective

To systematically identify and appraise existing risk prediction models for EN aspiration in adult inpatients.

Data Sources

A systematic search was conducted across PubMed, Web of Science Core Collection, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Biomedical Literature Database (CBM) and VIP Database from inception to 1 March 2025.

Study Design

Systematic review of observational studies.

Review Methods

Two researchers independently performed literature screening and data extraction using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). The Prediction Model Risk of Bias Assessment Tool (PROBAST) was employed to evaluate both the risk of bias and the clinical applicability of the included models.

Results

A total of 17 articles, encompassing 29 prediction models, were included. The incidence of aspiration was 9.45%–57.00%. Meta-analysis of high-frequency predictors identified the following significant predictors of aspiration: history of aspiration, depth of endotracheal intubation, impaired consciousness, sedation use, nutritional risk, mechanical ventilation and gastric residual volume (GRV). The area under the curve (AUC) was 0.771–0.992. Internal validation was performed in 12 studies, while both internal and external validation were conducted in 5 studies. All studies demonstrated a high risk of bias, primarily attributed to retrospective design, geographic bias (all from different parts of China), inadequate data analysis, insufficient validation strategies and lack of transparency in the research process.

Conclusion

Current risk prediction models for enteral nutrition-associated aspiration show moderate to high discriminative accuracy but suffer from critical methodological limitations, including retrospective design, geographic bias (all models derived from Chinese cohorts, limiting global generalisability) and inconsistent outcome definitions.

Implications for Clinical Practice

Recognising the high bias of existing models, prospective multicentre data and standardised diagnostics are needed to develop more accurate and clinically applicable predictive models for enteral nutrition malabsorption.

Research Capability and Influencing Factors Among Clinical Nurses: A Multicentre Cross‐Sectional Study

ABSTRACT

Aim

To evaluate the research capability of clinical nurses in China and identify the determinants associated with their capability.

Background

As nursing evolves into an increasingly independent discipline, the research capability of clinical nurses has become critical for the development of the profession, advancing evidence-based practice and improving patient care quality.

Methods

A multicentre cross-sectional survey was conducted using convenience sampling from September 2023 to February 2024, among clinical nurses in tertiary hospitals across three provinces in China. The Nursing Research Capability Self-Assessment Scale was used to assess the research capability of the nurses. Chi-square tests, one-way analysis of variance and multiple linear regression were used to examine factors associated with research capability. The Strengthening the Reporting of Observational Studies in Epidemiology was followed.

Results

A total of 1074 clinical nurses participated. The mean research capability score was 89.11 ± 27.69, reflecting a moderate level of research capability. However, two dimensions of research questions and literature review received lower scores. Multiple linear regression analysis identified that education level, professional title, administrative position and nursing job title (all p < 0.05) were independent predictors of research capability.

Conclusions

Clinical nurses exhibit moderate research capability, with notable deficiencies in formulating research questions and conducting literature reviews. Key factors influencing research capability include education, professional title, administrative position, and job title. Targeted training and development programmes should address these factors to enhance nurses' research competence and advance nursing science.

Association between anthropometric indices and early arterial stiffness in patients with type 2 diabetes in China: a cross-sectional study

Por: Luo · J. · Zhou · H. · Yu · F. · Zhou · Q. · Wu · X. · Liu · Q. · Gan · S.
Objective

The waist-hip ratio (WHR) and waist-height ratio (WHtR) are associated with arterial stiffness (AS), yet there is limited research on this topic in patients with type 2 diabetes mellitus (T2DM). This study aims to investigate the relationship between WHR, WHtR and AS in patients with T2DM.

Setting

This cross-sectional study used data from patients with T2DM enrolled in the Metabolic Disease Management Center (MMC) at Changde Hospital, Xiangya School of Medicine, Central South University between May 2020 and October 2023.

Participants

A total of 3201 patients were collected, and after applying the exclusion criteria, data from 3006 patients were finally analysed.

Primary outcomes

The primary outcome of AS was assessed using brachial-ankle pulse wave velocity (baPWV).

Results

After adjusting for gender and age, there was an increasing trend in baPWV across the quartiles of WHR and WHtR. In the multivariate regression analysis adjusting for confounding factors, it was observed that for each one-unit increase in the WHR z-score, baPWV increased by 18.1 cm/s (95% CI: 7.8 to 28.4). Similarly, for each one-unit increase in the WHtR z-score, baPWV increased by 28.6 cm/s (95% CI: 16.6 to 40.6). In the multivariate logistic regression analysis, after fully adjusting for confounding factors, it was found that for every one-unit increase in the WHR z-score, the OR for elevated baPWV was 1.2 (95% CI: 1.1 to 1.4). Similarly, for every one-unit increase in the WHtR z-score, the OR for elevated baPWV was 1.3 (95% CI: 1.1 to 1.5). According to the generalised additive model, we found that WHR and WHtR were positively correlated with baPWV and elevated baPWV. Subgroup analysis revealed that elevated WHR and WHtR are significant predictors of AS, with this association being substantially amplified by poor glycaemic control (glycated haemoglobin ≥7%).

Conclusion

In Chinese patients with T2DM, both WHR and WHtR are positively and independently associated with baPWV and the presence of elevated baPWV.

Impact of intraoperative explanation combined with surgical video review on anatomy learning in laparoscopic distal gastrectomy

Por: Ding · Y. · Liu · X. · Cai · Y. · Cheng · F. · Shi · L. · Wu · K.
Objective

To investigate the educational value of combining intraoperative explanations with laparoscopic surgical video reviews for teaching the local anatomy of the stomach.

Methods

Thirty resident physicians undergoing standardised training in our hospital, including undergraduate resident physicians and clinical-type postgraduates in surgery who had not participated in radical gastrectomy for gastric cancer, were selected as study subjects. They were randomly divided into an experimental group and a control group, with 15 participants in each group. The experimental group received instruction through intraoperative explanations combined with laparoscopic surgical video reviews, while the control group participated in surgery without additional instructional methods. After the teaching sessions, both groups underwent clinical practice assessments, theoretical examinations and evaluations of teaching satisfaction. The distribution of the data was assessed using the Shapiro-Wilk normality test along with Quantile-Quantile plots. Two-way analysis of variance was employed to evaluate the main effects and interaction effects of clinical practice scores across different groups and student types. Statistical power was examined through post hoc power analysis.

Results

The clinical practice assessment results, theoretical examination scores and teaching satisfaction ratings of the experimental group were significantly higher than those of the control group, with all differences reaching statistical significance (p

Conclusion

Combining intraoperative explanations with laparoscopic surgical video reviews for teaching local anatomy during distal gastrectomy is more effective than participation in surgery alone. This approach allows students to review surgical videos at their convenience, enhancing their understanding and mastery of local anatomical structures and significantly improving the quality of local anatomy education for resident physicians.

Objectives

Left ventricular assist devices (LVADs) have become important treatments for end-stage heart failure; however, studies of post-LVAD life experiences are limited. The aim of this study was to investigate post-LVAD life experiences and coping strategies in patients who underwent LVAD implantation as destination therapy.

Design

This study used a qualitative descriptive design with a phenomenological approach. Semistructured face-to-face interviews were conducted to collect data. The data were analysed via inductive content analysis.

Setting

Participants were recruited from a high-volume cardiovascular disease centre in Nanjing, China.

Participants

A purposive method was employed to recruit 10 patients who had an LVAD support time of more than 6 months.

Results

The life experiences of participants who underwent LVAD implantation can be summarised into two main themes and five subthemes: hope (subthemes: LVADs signify survival and hope for returning to normal life) and fear (subthemes: fear of device malfunction, fear of complications and fear of increasing the family burden). Coping strategies for fear, including self-support, family support, social support and professional healthcare support, were noted.

Conclusions

Patients who undergo LVAD implantation experience significant fluctuations in their life experiences. Attention should be given to the physical and mental health of patients with an LVAD, and individualised professional consultation and nursing should be provided.

Worldwide trends in mortality for aortic aneurysm from 1990 to 2021 and projections to 2036: a systematic analysis of data from the Global Burden of Disease Study 2021

Objectives

To analyse global trends in aortic aneurysm mortality from 1990 to 2021 and project future trends through 2036, examining variations across Socio-Demographic Index (SDI) quintiles, regions, nations, age groups and sexes.

Design

We conducted a comprehensive analysis using mortality data from the Global Burden of Disease (GBD) Study 2021.

Setting

Data were obtained from the GBD 2021 database, covering 204 countries and territories across 21 GBD regions.

Participants

Individuals with aortic aneurysm-related mortality between 1990 and 2021.

Main outcome measures

Absolute deaths and age-standardised mortality rates (ASMR) per 100 000 from 1990 to 2021, stratified by SDI quintiles, GBD regions and individual nations. Temporal trends were quantified using estimated annual percentage change (EAPC) and net drift, while decomposition analysis assessed contributions of population ageing, growth and epidemiological changes to mortality patterns. Risk factor attribution across regions and SDI levels was examined, alongside projections of ASMR and deaths through 2036 using the Nordic prediction method.

Results

Global aortic aneurysm deaths increased from 88.35 thousand in 1990 to 153.93 thousand in 2021, while ASMR decreased from 2.54 to 1.86 per 100 000 (EAPC: –1.28%). High SDI regions showed significant ASMR declines (EAPC: –1.982%), while low-middle SDI regions experienced increases (EAPC: 1.272%). Marked regional variations were observed, with Australasia showing the largest decrease (EAPC: –4.114%) and Central Asia the highest increase (EAPC: 2.498%). Japan diverged from other developed countries with significant mortality increase. Decomposition analysis revealed that increased mortality was primarily driven by population growth (59.109 million) and ageing (46.385 million), partially offset by epidemiological improvements (–39.92 million). The male-to-female ASMR ratio decreased globally from 2.45 to 2.00. Tobacco remained the leading risk factor globally, while body mass index emerged as an increasing concern. Projections indicate a slight global ASMR decrease by 2036, with concerning increases in regions like high-income Asia Pacific and South Asia.

Conclusions

Despite declining global ASMR, the absolute burden of aortic aneurysm mortality continues to grow with significant regional and sex-based disparities. These findings highlight the need for targeted interventions, particularly in regions facing increasing mortality rates, and emphasise the importance of addressing modifiable risk factors while strengthening healthcare infrastructure in vulnerable areas.

Consequences in critically ill patients with prolonged mechanical ventilation after diaphragmatic stimulation techniques: a systematic review and meta-analysis

Por: Tong · S. · Yang · Y. · Li · Y. · Liu · L. · Chang · W.
Objective

Prolonged mechanical ventilation (MV) may lead to poor outcomes. This systematic review and meta-analysis aimed to investigate the effects of diaphragmatic stimulation on the duration of MV (DMV), the intensive care unit (ICU) length of stay (ILOS), the proportion of patients successfully weaned and maximum inspiratory pressure (MIP) in patients with prolonged MV.

Design

Systematic review and meta-analysis.

Data sources

Cochrane library, Embase, Pubmed and Web of Science up to December 2024.

Eligibility criteria for selecting studies

Randomised controlled trials (RCTs) and cohort studies evaluating the outcomes of patients with prolonged MV after diaphragmatic stimulation were included up to December 2024.

Data extraction and synthesis

All articles were independently assessed by two reviewers, and a third reviewer was consulted to resolve different evaluations. Newcastle-Ottawa Scale (NOS) and the Cochrane Collaboration tool in RevMan V.5.3 software (The Cochrane Collaboration, 2014) were applied to assess the quality of cohort studies or RCTs. The meta-analysis was carried out with RevMan V.5.3 software, applying a random-effects model and presenting results with 95% CIs. Heterogeneity was examined using the Higgins I² statistic, and subgroup analyses were carried out to investigate possible contributors to heterogeneity. Sensitivity analyses were further conducted in Stata 18.0 (StataCorp LP, College Station, TX, USA). Potential publication bias was assessed through funnel plots combined with Egger’s regression test. For each outcome, the certainty of evidence was appraised according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE).

Results

Ten studies involving 802 patients (349 received diaphragmatic stimulation) were included. The meta-analysis indicated that patients receiving diaphragmatic stimulation had shorter DMV (mean differences (MD) –5.69 d, 95% CI –10.99 to –0.39, p=0.04) and ILOS (MD –5.48 d, 95% CI –10.72 to –0.24, p=0.04). The proportion of patients successfully weaned was larger in patients with diaphragmatic stimulation (risk ratios (RR) 1.25, 95% CI 1.01 to 1.53, p=0.04). The MIP increased compared with the control group.

Conclusions

The promising results suggest that diaphragmatic stimulation has the potential to shorten DMV and ILOS and accelerate weaning from ventilator.
