To analyse current Glasgow Coma Scale practice among emergency nurses in China and identify factors influencing assessment quality.
A quantitative, multicenter cross-sectional design.
A convenience sample of 1740 emergency nurses from secondary and tertiary hospitals across 21 provinces completed a validated structured questionnaire between March and April 2025. Participants had at least 6 months of emergency nursing experience. Data analysis included descriptive statistics, chi-square tests, and multiple logistic regression to examine factors influencing correct Glasgow Coma Scale application.
Participants had a mean age of 29.8 years (SD = 6.2). Only 52.5% of nurses demonstrated correct Glasgow Coma Scale application despite 97.0% having theoretical knowledge of scoring criteria. While 56.8% had received Glasgow Coma Scale training, significant standardisation deficiencies emerged. Notably, 41.8% of departments lacked operational guidelines, and 53.7% of nurses experienced scoring disagreements with colleagues. Clinical utilisation varied substantially by patient population: traumatic brain injury (97.8%), neurological diseases (96.9%), and systemic critical illness (85.8%). Multivariate analysis identified six significant factors influencing correct application: standardised training (OR = 2.252, 95% CI: 1.789–2.825), manageable workload ≤ 4 patients/shift (OR = 1.652, 95% CI: 1.327–2.057), departmental guidelines (OR = 1.523, 95% CI: 1.233–1.881), extensive work experience ≥ 9 years (OR = 1.534, 95% CI: 1.182–1.992), while multidisciplinary collaboration issues (OR = 0.559, 95% CI: 0.439–0.712) and special patient experience (OR = 0.520, 95% CI: 0.406–0.666) were associated with reduced accuracy.
Substantial standardisation challenges exist in Glasgow Coma Scale practice among Chinese emergency nurses, characterised by significant gaps between theoretical knowledge and clinical application. Major barriers include insufficient standardised guidelines, inconsistent training approaches, and inadequate interdisciplinary collaboration.
Healthcare administrators should develop national standardised guidelines, implement simulation-based training programs, optimise emergency workflows, and integrate alternative assessment tools to enhance consciousness assessment accuracy and improve patient safety.

To identify distinct social network types among young-old adults based on the characteristics of social network structure and to explore the relationship between different types, socio-demographic characteristics and subjective cognitive decline.
A cross-sectional study was conducted from July 2022 to October 2023.
A total of 652 young-old adults aged 60–74 years completed the sociodemographic questionnaire, the subjective cognitive decline questionnaire-9 and the self-designed egocentric social network questionnaire. The types of social networks were identified by latent profile analysis. Univariate analysis and binary logistic regression were used to analyse the influencing factors of subjective cognitive decline.
The incidence of subjective cognitive decline was 38%. Social networks of young-old adults tended to be large, predominantly family-centred and characterised by strong contact strength, high density and significant demographic heterogeneity among network members. Four social network types were identified: diverse-moderate, family-dense, family-strong and friend-loose. Young-old adults embedded in the family-dense and family-strong types were more likely to develop subjective cognitive decline than those in the diverse-moderate type. Additionally, age, education level, previous occupation, daily sleep duration and exercise were related to the incidence of subjective cognitive decline.
The findings highlight the relatively high incidence of subjective cognitive decline in young-old adults that is notably influenced by the type of social network they are embedded in. More attention needs to be paid to identifying and supporting young-old adults at high risk of subjective cognitive decline, especially to promote their social integration and friend network building, to improve their subjective cognitive function.
The findings emphasise the importance of considering the structure and composition of social networks when addressing subjective cognitive decline among young-old adults. A diversified social network incorporating both familial and friendship ties may provide enhanced cognitive protection. Therefore, interventions targeting subjective cognitive decline should promote the expansion of friendship-based relationships and foster the development of more heterogeneous and multi-source networks.

To assess the supply, demand, and utilisation of master's degree nurses in China's top-tier hospitals and identify recruitment and retention challenges.
A convergent parallel mixed-methods design.
From January and September 2022, eight top-tier hospitals in mainland China were selected using convenience sampling. The proportion of master's degree nurses, turnover rates, and recruitment outcomes were investigated and analysed using descriptive statistics. Concurrently, seven nursing administrators from these eight hospitals were interviewed using semi-structured interviews, and transcribed data were thematically analysed through inductive content analysis.
Among the eight hospitals surveyed, the average proportion of master's degree nurses was 3.58% (range: 0.58%–9.43%). The average ratio of planned to actual recruitment was 3.28, with four hospitals showing near parity (approximately 1:1) and three institutions failing to recruit any master's degree nurses. The annual turnover rate of master's degree nurses was 1.18%. Three themes emerged from the qualitative analysis: (1) shortages coexisting with oversupply; (2) nursing leaders' retention efforts versus limited institutional policy support; and (3) prioritisation of research and management over advanced clinical roles.
In China, even among top-tier hospitals, the proportion of master's degree nurses remains relatively low. There is an overall shortage of these nurses, juxtaposed with localised oversupply in specific institutions. Promotion to nursing supervisor or administrative roles is the only developmental pathway, while structured career progression pathways for advanced nursing practice remain conspicuously absent.
The study highlights the need to develop targeted policies that support the career advancement of master's degree nurses, particularly by expanding career options in Advanced Practice Nurses (APNs) rather than limiting roles to nursing management or education. This shift would better leverage their clinical expertise and strengthen healthcare systems through specialised practice and innovation.
What problem did the study address?: This study maps the supply–demand dynamics of master's degree nurses in leading hospitals and identifies retention, utilisation, and motivation policies and strategies from the perspective of nursing administrators. What were the main findings?: The proportion of master's degree nurses is low in China's top hospitals. There is both an oversupply and a shortage of master's degree nurses. Neither the government nor hospitals have policies in place to encourage the clinical involvement of master's degree nurses, and their career progression is limited to managerial roles. Where and on whom will the research have an impact?: Nursing administrators and other health policy makers in China and comparable global health systems will be affected. It will also influence nursing associations, nursing educators, and general nurses.

The study aims to investigate patients' perceptions of recurrence risk associated with atrial fibrillation, with the goal of establishing a theoretical foundation for developing future measurement scale and intervention strategies.
A qualitative interview study.
Seventeen patients diagnosed with atrial fibrillation at a Grade-A tertiary hospital participated in semi-structured, in-depth interviews conducted between October and December 2024. Participants were selected via purposive sampling. The data were analysed employing thematic analysis in accordance with Colaizzi's method. The study adhered to the Consolidated Criteria for Reporting Qualitative Research checklist.
The perceptions of recurrence risk among patients with atrial fibrillation can be summarised into five themes: (1) perceived likelihood of recurrence, (2) perceived severity of recurrence, (3) perceived triggers of recurrence, (4) emotional reaction to recurrence, and (5) efficacy perception of managing recurrence risk.
Perceptions of recurrence risk among patients with atrial fibrillation are diverse and often underestimated due to limited knowledge and subjective symptom interpretation, affecting health behaviours. Understanding patients' subjective appraisals, emotions, and perceived efficacy is essential. Validated assessment tools and tailored risk communication may enhance self-management and support targeted interventions.
This study provides critical insights into how atrial fibrillation patients perceive their risk of recurrence. It also provides a theoretical foundation for creating validated assessment tools and tailoring individualised health education and intervention programmes.
Patients were involved in the study design, data collection, and interpretation of findings. Their contributions included providing feedback on the initial interview guide to ensure relevance and clarity, participating in in-depth interviews to share their lived experiences with atrial fibrillation recurrence, and offering reflections on key themes emerging from the data.
This study aimed to examine the level of vicarious posttraumatic growth among intensive care unit nurses in China and explore the mediating role of death coping ability in the relationship between moral resilience and vicarious posttraumatic growth.
A multicentre, cross-sectional study was conducted in accordance with the STROBE guidelines.
Between January and March 2025, a questionnaire survey was conducted among 666 intensive care unit nurses from nine tertiary Grade A hospitals across five provinces in China. Participants completed three standardised instruments: the Rushton Moral Resilience Scale, the Coping with Death Scale–Short Version, and the Vicarious Posttraumatic Growth Inventory. We used IBM SPSS 27.0 for descriptive statistics, univariate analyses, and correlation analyses, and employed AMOS 27.0 to perform structural equation modelling for testing mediation effects.
Intensive care unit nurses demonstrated a moderate level of vicarious posttraumatic growth. Moral resilience was positively associated with both death coping ability and vicarious posttraumatic growth. Death coping ability was found to play a partial mediating role in the relationship between moral resilience and vicarious posttraumatic growth.
Moral resilience and death coping ability are key factors associated with vicarious posttraumatic growth among intensive care unit nurses. Nurses with stronger moral resilience are more likely to cope constructively with death-related stress, which may support psychological growth in trauma-intensive environments.
This study highlights the need to enhance intensive care unit nurses' moral and emotional capacities through ethics education, emotional coping training, and institutional support strategies. Strengthening these competencies may foster professional development and mental wellbeing in critical care settings.

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.by Linlin Bao, Haibo Zhao, Haiyue Ren, Chong Wang, Su Fang
Hair follicle stem cells (HFSCs) play critical roles in adult hair regeneration, owing to its self-renewal and multipotent differentiation properties. Emerging evidence has shown that long noncoding RNAs (LncRNAs) are implicated in biological processes such as proliferation, differentiation and apoptosis. However, the specific role of LncRNA RP11-818O24.3 in regulating HFSCs remains unclear. To explore the effect of LncRNA RP11-818O24.3 on HFSCs, stable LncRNA RP11-818O24.3 overexpression and knockdown HFSCs were established using a lentivirus vector system. The effect of LncRNA RP11-818O24.3 on proliferation was evaluated by Cell Counting Kit-8 (CCK8) and EdU incorporation experiments. The differentiation of HFSCs into neurons and keratinocyte stem cells was detected by immunofluorescence staining. We showed that LncRNA RP11-818O24.3 overexpression promoted the proliferation and inhibited cell apoptosis in HFSCs. High levels of LncRNA RP11-818O24.3 promoted the differentiation of HFSCs into CD34+K15+ keratinocyte progenitors and CD34+Nestin+neuron-specific enolase (NSE)+ neural stem cells. Additionally, LncRNA RP11-818O24.3 increased fibroblast growth factor 2 (FGF2) expression and the subsequent activation of the PI3K/AKT signaling pathway. These data demonstrated that LncRNA RP11-818O24.3 promotes self-renewal, differentiation, and the capability to inhibit apoptosis of HFSCs via FGF2 mediated PI3K/AKT signaling pathway, highlighting its potential role as a therapeutic strategy for treating hair loss diseases.Childhood obesity has surged globally, leading to various metabolic comorbidities and increased cardiovascular risks. Early intervention in lifestyle and feeding practices during infancy is crucial to mitigate these risks. This study evaluates the efficacy of a mobile web app-based intervention tool, named the Feeding, Lifestyle, Activity Goals (FLAGs) to promote healthier eating behaviours and lifestyle habits in infants from birth to 12 months.
This two-arm randomised controlled trial will enrol 220 caregiver-infant pairs per arm at KK Women’s and Children’s Hospital, Singapore, with recruitment expected from January to December 2025. Eligible participants include women at ≥34 weeks’ gestation or up to 3 days post delivery with pre-pregnancy overweight/obesity (body mass index (BMI) >23 kg/m2) and/or a diagnosis of diabetes. Caregiver-infant pairs will be randomised to the FLAGs intervention or control group. Over 12 months, both groups will receive standard infant care. The intervention group will undergo regular assessments via the FLAGs web app built-in assessment tool, assessing infant feeding practices, sedentary behaviour and physical activity. The intervention group will also receive FLAGs personalised guidance and weekly digital nudges. Maternal and infant data will be collected at baseline and at 12 months. Primary outcomes are infant BMI, weight-for-length and body composition at 12 months. Secondary outcomes include lifestyle behaviours and eating habits assessed through validated questionnaires when the infants are 1 year old. We will perform both intention-to-treat and per protocol analysis.
Ethical approval has been obtained from the SingHealth Centralised Institutional Review Board (Ref: 2024/3224). Written informed consent will be obtained from all participants. Study findings will be disseminated via peer-reviewed publications and academic conferences, with de-identified data available on reasonable request. This trial is registered on ClinicalTrials.gov (ID: NCT06457750).
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.
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.

Diabetic retinopathy (DR) in pregnancy can cause blindness. National guidelines recommend at least one eye examination in early pregnancy, then ideally 3-monthly, through to the postpartum for pregnant women with pregestational diabetes. Here we examined adherence rates, barriers and enablers to recommended DR screening guidelines.
Cross-sectional survey study, as part of a larger prospective cohort study.
Participants were recruited from two tertiary maternity hospitals in Melbourne, Australia.
Of the 173 pregnant women with type 1 (T1D) or type 2 diabetes (T2D) in the main cohort study, with an additional four who participated solely in this survey study, 130 (74.3%) completed the survey.
This study calculated rates of adherence to guideline-recommended DR screening schedules and collected data on the enablers and barriers to attendance using a modified Compliance with Annual Diabetic Eye Exams Survey. Each of the 5-point Likert-scale survey items was compared between adherent and non-adherent participants using the Wilcoxon rank-sum test and logistic regression models were constructed to quantify associations as ORs.
A retinal assessment was undertaken at least once during pregnancy in 86.3% of participants, but only 40.9% attended during their first trimester and only 21.2% attended the recommended number of examinations. Competing priorities were the main barriers to adherence, with eye examinations ranked as the fourth priority (IQR 4th–5th) among other health appointments during pregnancy. Meanwhile, knowledge of the benefits of eye screening examinations, eye-check reminders and support from relatives was identified as enablers.
Despite the risk of worsening DR during pregnancy, less than half of the participants adhered to recommended screening guidelines, suggesting that eye health is not a priority. Proactive measures to integrate care are needed to prevent visual loss in this growing population.
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.

This study analysed the clinical outcomes and healthcare costs associated with diabetic foot ulcer (DFU) within a tertiary healthcare centre in Singapore.
This is a retrospective, single-centre study. Patient data were extracted from the hospital’s electronic health system, including demographic, clinical and hospitalisation information. Hospitalisation costs were categorised into DFU-related and other hospitalisation costs. A one-way sensitivity analysis was performed to estimate the total healthcare costs associated with DFU.
Tertiary centre within a population suffering from a diabetic epidemic.
All patients aged 18 years or older who received DFU treatment between January 2019 and December 2023 at the Singapore General Hospital were included.
A total of 2857 DFU patients were included in the study. In-hospital mortality remained stable at 5%–6% annually. Among the cohort, 39.1% underwent minor amputations, 19.6% had major amputations and 9.0% experienced both minor and major amputations. The median length of stay for surgical patients ranged from 10 (IQR 4–24) to 13 days (IQR 6–31), compared with 4 (IQR 2–8) to 5 (IQR 3–9.5) days for non-surgical patients. Total costs per admission for patients with DFU-related surgery ranged from US$28 588.96 to US$34 204.77, while for those without surgery, costs ranged from US$6637.59 to US$7955.23. Total hospitalisation costs for DFU during the study period ranged from US$65.87 million to US$72.16 million. All figures were inflation adjusted to 2023 US dollars.
DFU poses a significant clinical and economic burden in Singapore. Understanding the costs associated with DFU is essential for resource allocation and planning in DFU management.
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.

A novel advanced synthetic bioactive glass matrix was studied in patients with non-healing diabetic foot ulcers (DFUs). Bioactive glasses can be constructed to be biocompatible, with water-soluble materials in multiple geometries including fibre scaffolds that mimic the 3D architecture of a fibrin clot. In this trial, chronic, Wagner Grade 1 DFUs were randomised to receive borate-based bioactive glass Fibre Matrix (BBGFM) plus standard of care (SOC) therapy for 12 weeks or SOC alone. The primary study endpoint was the proportion of subjects that obtained complete wound closure at 12 weeks. Secondary endpoints included time to achieve complete wound closure at 12 weeks. In the modified intent-to-treat (mITT) analysis, 48% (32/67) treated with BBGFM plus SOC healed at 12 weeks compared to 24% (16/66) with SOC alone (p = 0.007). In the per protocol (PP) population, 73% (32/44) of subjects treated with BBGFM plus SOC healed versus 42% (16/38) in the SOC group (p = 0.007). Based on the success of this trial, BBGFM demonstrates faster healing of DFUs compared to SOC and should be considered in the treatment armamentarium for Wagner Grade 1 DFUs. Future trials should investigate the use of BBGFM for healing deeper chronic DFUs, other wound aetiologies, or complex surgical wounds.

ObjectiveTo develop a predictive framework integrating machine learning and clinical parameters for postoperative pulmonary complications (PPCs) in non-small cell lung cancer (NSCLC) patients undergoing video-assisted thoracic surgery (VATS).
MethodsThis retrospective study analyzed 286 NSCLC patients (2022–2024), incorporating 13 demographic, metabolic-inflammatory, and surgical variables. An Improved Blood-Sucking Leech Optimizer (IBSLO) enhanced via Cubic mapping and opposition-based learning was developed. Model performance was evaluated using AUC-ROC, F1-score, and decision curve analysis (DCA). SHAP interpretation identified key predictors.
ResultsThe IBSLO demonstrated significantly superior convergence performance versus original BSLO, ant lion optimizer (ALO), Harris hawks optimization (HHO), and whale optimization algorithm (WOA) across all 12 CEC2022 test functions. Subsequently, the IBSLO-optimized automated machine learning (AutoML) model achieved ROC-AUC/PR-AUC values of 0.9038/0.8091 (training set) and 0.8775/0.8175 (testing set), significantly outperforming four baseline models: logistic regression (LR), support vector machine (SVM), XGBoost, and LightGBM. SHAP interpretability identified six key predictors: preoperative leukocyte count, body mass index (BMI), surgical approach, age, intraoperative blood loss, and C-reactive protein (CRP). Decision curve analysis demonstrated significantly higher net clinical benefit of the AutoML model compared to conventional methods across expanded threshold probability ranges (training set: 8–99%; testing set: 3–80%).
ConclusionThis study establishes an interpretable machine learning framework that improves preoperative risk stratification for NSCLC patients, offering actionable guidance for thoracic oncology practice.

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

PurposeSleep quality is a multidimensional construct encompassing the effectiveness and restorativeness of sleep. The pre-sleep arousal scale is a widely used instrument for evaluating aspects of arousal that are closely related to sleep quality. This study aimed to evaluate the psychometric properties of the Korean version of the pre-sleep arousal scale (K-PSAS).
MethodsWe performed a secondary analysis of cross-sectional data from 286 adults aged 19–70 years who used electronic cigarettes or heated tobacco products. The original PSAS was translated into Korean, with content validity assessed by experts. Construct validity was evaluated via exploratory factor analysis, and concurrent validity was assessed by correlating the K-PSAS with the Insomnia Severity Index, Pittsburgh Sleep Quality Index, and Hospital Anxiety and Depression Scale. Reliability was examined using Cronbach’s α, and split-half reliability coefficient.
ResultsBoth the item-level content validity index for all items and the scale-level content validity index average for the K-PSAS-16 were 1.0. After removing the survey item on “being mentally alert and active at bedtime” (item 13) due to low factor loading, the K-PSAS-15 demonstrated a two-factor structure, with somatic and cognitive arousal factors explaining 42.36% and 10.19% of the variance, respectively. A significant positive correlation was observed between the two factors (ρ = 0.61, p Conclusion
The K-PSAS-15, which excludes one poorly performing item from the original scale, is a reliable and valid tool for assessing pre-sleep arousal.

BackgroundSarcopenia is an age-associated disorder characterized by a progressive decline in skeletal muscle mass, strength, and physical function. The condition is linked to low levels of anabolic hormones such as insulin-like growth factor 1 (IGF-1), with its downstream phosphatidylinositol 3 kinase (PI3K)/ protein kinase B (AKT)/ forkhead box protein O3 (FOXO3) signaling pathway. There is growing evidence that resistance training (RT) or vibration training (VT) could improve physical functioning in individuals with sarcopenia. However, the related physiological influence of exercise on sarcopenia remains elusive.
MethodThis prospective randomized controlled trial will be conducted among 96 participants, aged between 65 and 80 years. In participants, sarcopenia diagnosis will be confirmed based on the Asian Working Group for Sarcopenia criteria, and participants will be randomized into either control, RT, VT, or RVT (combined RT and VT) groups. The intervention will last 12 weeks, with assessments performed at baseline, 12 weeks (after intervention), and 24 weeks (follow-up). The primary outcomes will include skeletal muscle mass, handgrip strength, and gait speed. Secondary outcomes comprise IGF-1 concentrations, PI3K/AKT and FOXO3 protein activity, quality of life, and timed-up-and-go test performance assessments.
DiscussionThis clinical study aims to elucidate the potential modulation of molecular mechanisms in vivo for combined RT and VT in sarcopenia patients and to identify the effects of the intervention on physical function.

Heroin users have a high burden of respiratory morbidity, including premature lung function impairment. Further, methadone treatment has been found to aggravate lung function impairment and can independently cause asthma. However, the lung function status among heroin users on medication-assisted therapy (MAT) in Tanzania is yet to be studied. This study aimed to assess the magnitude, pattern and factors associated with lung function impairment among heroin users on MAT.
This was a quantitative, analytical cross-sectional study.
This study was conducted at MAT Clinic at Muhimbili National Hospital in Dar-es-Salaam, Tanzania.
Individuals aged 18 years or above with heroin use disorder on stable dose of methadone without heroin withdrawal symptoms (Maintenance Phase of Treatment) were recruited.
Participants were enrolled through systematic sampling technique. Data were collected using a questionnaire, and lung functions were measured using a spirometer. Lung function impairment was defined as the percentage of participants with forced expiratory volume in 1 s (FEV1)
We enrolled 302 participants into the study (mean age of 42.78±7.56 years). Lung function impairment was observed in 28.5% of participants, with an average age of 44±8 years. Restrictive lung disease was the most common pattern of lung function impairment affecting 13.2% of the participants. The predictors of lung function impairment were being underweight (OR) 4.73, 95% CI) 2.61–8.59, p
Heroin users on MAT have a high magnitude of lung function impairment. Routine lung function testing is recommended.
