BackgroundStandardized guidelines for optimal tunnel length in tunneled peripherally inserted central catheters (PICCs) are lacking.
ObjectivesThe objective of this study was to evaluate the real-world impact of tunnel length on clinical outcomes.
MethodsThis retrospective cohort study included 207 cancer patients who received tunneled PICCs, categorized into a control group (tunnel length > 4 cm, n = 134) and an observation group (tunnel length ≤ 4 cm, n = 73). Propensity score matching (PSM) was used to address baseline heterogeneity. Cox regression analyses were used to assess the risk of complication during a 120-day follow-up.
ResultsCompared to the control group (tunnel length > 4 cm), the observation group (tunnel length ≤ 4 cm) had a significantly higher adjusted overall complication risk (HR = 2.92, 95% CI: 1.07–7.94, P = 0.036) and unplanned catheter removal rate (4.4% vs. 0.0%, P = 0.027), confirming the safety of longer tunnels despite comparable comfort levels between groups. After PSM, Cox regression analysis showed results consistent with those from the unmatched cohort. Subgroup analyses revealed a reduced risk of complications with longer tunnels in patients with BMI ≤ 25 kg/m² (HR = 0.29, 95% CI: 0.11–0.82), without hypertension (HR = 0.36, 95% CI: 0.13–1.00), without diabetes (HR = 0.38, 95% CI: 0.15–0.97), and with solid tumors (HR = 0.31, 95% CI: 0.11–0.85).
ConclusionThe results show that tunnel lengths > 4 cm reduce overall complications and prolong catheter retention, supporting the implementation of standardized protocols while advocating for personalized adjustments based on BMI, comorbidities, and cancer type.

BackgroundThe overlap between non-erosive reflux disease (NERD) and epigastric pain syndrome (EPS, a subtype of functional dyspepsia) is common, yet its associated factors remain poorly defined. We aimed to identify factors associated with symptom severity in NERD-EPS overlap, focusing on psychosocial and somatic factors.
MethodsIn this multicenter cross-sectional study, 800 patients meeting Rome IV criteria for NERD-EPS overlap were enrolled. Standardized questionnaires assessed gastrointestinal symptoms (GSRS), somatic symptoms (PHQ-15), anxiety/depression (PHQ-4), and sleep quality (SRSS). Multivariable regression models identified factors independently associated with GSRS scores, adjusted for demographics and clinical covariates. Interaction terms were tested to assess whether the association between one factor and GSRS scores varied across different levels of another factor.
ResultsOf the 800 patients, 67% were female, and the mean age was (44.50 ± 14.43) years. 67% had mild or more sleep problems, and 47% had anxiety or depression. Somatic symptoms (PHQ-15) showed the strongest association with GSRS scores (β = 0.617, P P P = 0.026). Urban residence (β = 0.071) and mixed labor type (β = −0.066) were also independently associated with symptom burden.
ConclusionSomatic symptoms, psychological distress, and sleep disturbances were the factors most strongly associated with symptom severity in NERD-EPS overlap, with additional contributions from younger age, male sex, and urban residence. Our findings advocate for integrated biopsychosocial interventions to alleviate symptom burden in this population.
This study aimed to identify potential categories of rotation stress among nurses undergoing standardised training and to explore the relevant factors associated with each profile.
Cross-sectional study.
Data were collected in November 2024 from three hospitals in Zunyi City, Guizhou Province, China.
Nurses undergoing standardised training were recruited for this study.
Convenience sampling method was used to recruit standardised training nurses in November 2024 from three hospitals in Zunyi City, Guizhou Province. The survey instruments used included demographic characteristics questionnaire, the Nursing Job Rotation Stress Scale and the Maslach Burnout Inventory. Latent profile analysis method was used to analyse rotation stress characteristics of nurses during standardised training. Additionally, logistic regression was performed to identify the factors influencing different characteristics.
A total of 493 nurses completed the questionnaires, of which 453 were valid, resulting in a validity rate of 91.88%. Rotation stress was classified into two profiles: ‘Low Emotional Response–Stress Adaptation Group’ (21.5%) and ‘High Emotional Response–Stress Distress Group’ (78.5%). Univariate analysis showed that highest degree (2=11.389, p=0.001), monthly night shifts (2=33.913, p2=20.858, p2=12.319, p2=35.754, p2=15.357, p=0.002) significantly influenced the two subgroups. Multivariable regression analysis revealed significant associations of monthly night shifts, pretraining work experience, training duration and burnout level (p
Nurses undergoing standardised training exhibit two distinct rotation stress profiles. Monthly night shifts, pretraining work experience, training duration and burnout are significant factors. Nursing managers should implement targeted interventions such as mindfulness, laughter therapy and emotional freedom techniques to mitigate stress and thereby enhance the quality of standardised training.
To gain an in-depth understanding of the experience of elderly joint replacement patients in making surgical decisions and to identify the needs of patients in the decision-making process.
A qualitative study, semistructured interviews were used and analysed by Colaizzi’s seven-step method.
This study was conducted in the orthopaedics department of a tertiary hospital in Wuhan.
Eligible participants were aged 60 years or older, scheduled for elective joint replacement surgery, cognitively intact and voluntarily consented to participate in the study.
We conducted interviews with a total of 25 elderly patients who underwent joint replacement surgery. This study reveals three themes and eight subthemes regarding the surgical decision-making experiences of elderly patients undergoing joint replacement. The three themes summarise three stages of the decision-making experience, respectively, trade-offs before decisions, feelings during decision-making and expectations after the decision. In the first stage, three subthemes were identified: (1) weighing the surgical risks and benefits, (2) assessment of medical proficiency and (3) low patient involvement in decision-making. In the second stage, three subthemes emerged: (1) internal fear, (2) self-doubt and (3) a heavy burden. In the third stage, two subthemes were identified: (1) a recovery process filled with confidence and (2) a desire for improved quality of life.
This study delves deep into the experiences of elderly patients undergoing joint replacement surgery during the surgical decision-making process. It provides a theoretical basis for decision-making assistance for elderly joint replacement patients, which is conducive to reducing patients’ decision-making conflicts and enhancing their decision-making capabilities.

The rarity of Late Pleistocene hominin remains from Insular Southeast Asia (ISEA) has hampered our ability to understand a crucial episode of human evolutionary history, namely, the global dispersal of Homo sapiens from Africa. Moreover, recent discoveries indicate a surprising level of taxic diversity during this time with at least two species—H. floresiensis and H. luzonensis—endemic to the region when H. sapiens first arrived. A third hominin dubbed the ‘Denisovans’ is shown from DNA evidence to have interbred with the ancestors of contemporary Indigenous populations across ISEA, New Guinea and Australia. Yet, the Denisovans have not been identified from the fossil record of the area despite recent breakthroughs in this regard on mainland East Asia. New excavations by our team at the Trader’s Cave in the Niah National Park (‘Niah Caves’), northern Borneo, have yielded an isolated hominin upper central permanent incisor dated with Optically Stimulated Luminescence dating of sediments to about 52 − 55 thousand years ago. Specimen SMD-TC-AA210 has a massive crown absolutely and relative to its root size, the crown is wide (mesiodistally) and relatively short (labiolingually). Morphologically, it exhibits a very strong degree of labial convexity, pronounced shovelling, and the bulging basal eminence exhibits several upward finger-like projections. Labial enamel wrinking on the enamel-dentine junction is expressed as two large ridges exhibiting numerous spine-like projections, and the lingual extensions on the enamel surface of the basal eminence are expressed as six extensions. This combination of crown size and morphological traits is not normally found in H. sapiens and instead characterises archaic members of Homo such as H. erectus, H. neanderthalensis and Middle Pleistocene hominins sharing a clade with H. heidelbergensis. The Trader’s Cave tooth suggests that an archaic hominin population inhabited northern Borneo just prior to or coincident with the arrival of H. sapiens as documented at the nearby West Mouth of the Niah Great Cave.by Yizhe Yang, Ruifeng Liang, Yan Luo, Doudou Zhu, Yi Liu, Yuyan Guo, Jiafen Zhang, Qiao Niu
ObjectiveInvestigate the Knowledge-Attitude-Practice (KAP) of students from Medical College towards emerging infectious diseases, and assess their impact, can provide a scientific basis and practical guidance for enhancing medico’s prevention and control capabilities.
MethodsA total of 2,395 participants from various grades and majors at Medical University were randomly selected using a stratified cluster sampling method. This cross-sectional study was conducted between April 25 and May 31, 2020, using a self-administered questionnaire developed on the Wenjuanxing platform to assess COVID-19-related knowledge, attitudes, and practices (KAP) among medical students.
ResultsA total of 2,245 participants (aged 16–28 years) were included in the study, coming from five medical disciplines: Clinical Medicine, Preventive Medicine, Nursing, Clinical Pharmacy, Health Inspection and Quarantine. The average scores for the COVID-19 epidemiological knowledge and the control measures for the epidemic were 4.92 ± 1.03 and 4.50 ± 0.78, respectively. Among them, the scores of epidemiological knowledge exhibited significant differences in sex, nation, type of dwelling place, major, grade, annual per capita household income, and age. The scores of preventive knowledge significantly differed by sex, major, grade, physical condition, and age. Further, behavioral data indicated that 96.0% of the students thought the pandemic had severely affected their daily life, while >90% maintained consistent mask usage and >80% insisted on health-protective practices. Practice scores finally varied significantly by sex, family structure, and ethnicity.
ConclusionsAltogether, medical students possess certain basic knowledge in controlling emerging infectious diseases, but some still generally suffer from insufficient cognitive depth and anxiety. Colleges can systematically enhance students’ rational cognitive level which include offering specialized courses as well as promoting cutting-edge research achievements, and through standardized operations stabilize their psychological states.

Prostate cancer (PCa) remains a leading cause of cancer-related mortality in men, with challenges in diagnosis and treatment due to tumor heterogeneity. This study identifies palmitoylation-related signature genes as potential diagnostic and therapeutic targets. Integrating GEO datasets, six differentially expressed genes (DEGs) linked to palmitoylation were identified. Machine learning algorithms (LASSO, RF, SVM) selected three core genes: TRPM4, LAMB3, and APOE. A diagnostic model based on these genes achieved an AUC of 0.929, demonstrating robust accuracy in distinguishing PCa from normal tissues. Functional analysis revealed roles in lipid metabolism and immune modulation, with ssGSEA highlighting correlations between key genes and immune cell infiltration. Experimental validation showed that LAMB3 overexpression suppressed PCa cell proliferation, migration, and invasion, while knockdown enhanced these processes. Molecular docking identified diethylstilbestrol as a potential therapeutic agent targeting LAMB3 and APOE. These findings emphasize the clinical relevance of palmitoylation-related genes in PCa diagnosis and therapy, offering novel biomarkers and insights for personalized treatment strategies.by Lijun Guo, Qiong Li, Jingyi Li, Feng Yang
Parkinson’s disease (PD) is a neurodegenerative disorder characterized by dopaminergic neuron loss and neuroinflammation, with emerging roles of peripheral immune dysregulation in disease progression. This study aimed to investigate the regulatory network of CD4 + T cells in PD through multi-omics integrative analysis. Transcriptomic and miRNA datasets from peripheral blood mononuclear cells (PBMCs) of 20 PD patients and 17 healthy controls were analyzed (GSE22491, GSE100054, GSE16658). Differential expression analysis identified 287 mRNAs and 73 miRNAs (|log₂(fold change)| ≥ 0.5, false discovery rate CD4 and SEMA6A. A competing endogenous RNA (ceRNA) network was constructed, comprising 38 lncRNAs, three miRNAs (miR-155-5p, miR-27a-3p, miR-27b-3p), and their target mRNAs CD4 and SEMA6A. Four lncRNAs (including XIST, NORAD, and INE1) were identified to functionally regulate CD4. Immune cell infiltration analysis revealed increased proportions of naïve CD4 + T cells and activated dendritic cells in PD patients. CD4 expression positively correlated with γδ T cells (r = 0.48, p = 0.032) and activated NK cells (r = 0.45, p = 0.048). Gene set enrichment analysis associated CD4 with neurodegenerative pathways (e.g., Parkinson’s disease: normalized enrichment score = 1.57, p = 0.002) and oxidative phosphorylation (normalized enrichment score = 1.89, p = 7.4 × 10 ⁻ ⁶). These findings highlight a peripheral CD4 + T cell-centric ceRNA network that modulates immune-metabolic crosstalk and neuroinflammation in PD. This study provides novel insights into immune-driven neurodegeneration and suggests potential therapeutic targets for PD through metabolic-immune reprogramming.This study aimed to develop and preliminarily validate the KAP scale for pain management in older adults with dementia among nursing assistants.
A cross-sectional study.
An initial item pool was constructed through literature reviews, semi-structured interviews and team discussions. Items were screened and optimised through two rounds of Delphi expert consultations, a pilot survey and item analysis, yielding a draft version of the scale. Psychometric evaluation was conducted to refine the scale into its final form.
The final KAP scale developed in this study comprised 31 items. The scale exhibited good content validity, with item-level content validity index (I-CVI) values ranging from 0.83 to 1.00. Exploratory factor analysis revealed that the scale extracted five factors, which accounted for 65.732% of the cumulative variance, and all items demonstrated rotated factor loadings > 0.5, indicating good construct validity. The Cronbach's α coefficients for the knowledge, attitudes and practices dimensions were 0.877, 0.915 and 0.935, respectively, and the split-half reliability coefficients were 0.909, 0.886 and 0.864.
The KAP scale for pain care in older adults with dementia developed in this study possesses good reliability and validity and can be used to assess the knowledge, attitudes and behavioural levels of nursing assistants in pain care.
This study developed and psychometrically validated a KAP scale specifically designed to assess pain care for older adults with dementia among nursing assistants. Clinical managers can utilise this tool to systematically identify deficiencies in staff members' knowledge, attitudes or practices, thereby providing scientific evidence for the development of targeted pain care training programs and pain management strategies. This contributes to enhancing nursing assistants' pain care competence, ultimately alleviating the pain burden of older adults with dementia and improving their quality of life.

BackgroundPreeclampsia (PE) is a life-threatening pregnancy disorder lacking reliable early biomarkers. While apoptosis is implicated in PE pathogenesis, the role of regulated necrotic cell death (necroptosis) remains poorly understood. This study aimed to identify necroptosis-related biomarkers, and further provide the potential natural compounds for PE with virtual screening.
MethodsPublic datasets (GSE66273 for training set; GSE44711 for validation set; GSE173193 for single-cell RNA-seq) were analyzed. Differentially expressed genes (DEGs) were screened using limma (|log2FC| > 1, P Results
The analysis of the GSE66273 dataset identified 367 DEGs. Intersection with necroptosis-related genes revealed 3 necroptosis-related DEGs (NRDEGs), from which BIRC3 was prioritized as hub gene through PPI networks and machine learning (random forest). BIRC3 demonstrated significant diagnostic potential in the discovery cohort (AUC = 0.933) and maintained strong performance in the independent validation cohort (AUC = 0.844). Single-cell analysis revealed BIRC3 was predominantly expressed in immune lineages, particularly NK/T cells, with a significantly higher proportion of BIRC3-positive cells in PE placentas (p Conclusion
This comprehensive analysis implicates necroptosis in PE pathogenesis. BIRC3 is proposed as a novel diagnostic biomarker and therapeutic target, with multi-omics validation underscoring its role in immune dysregulation and placental dysfunction.
Atrial fibrillation is a common arrhythmia in patients with ischaemic heart disease. New-onset atrial fibrillation after coronary revascularisation is associated with adverse cardiovascular outcomes. This study aimed to determine the long-term cumulative incidence of new-onset atrial fibrillation after percutaneous coronary intervention or coronary artery bypass grafting surgery.
A prospective observational cohort study in a real-world population setting, conducted at three tertiary centres, on new-onset atrial fibrillation incidence after percutaneous coronary intervention (N=123) or coronary artery bypass grafting (N=123). Heart rhythm was monitored the first 30 days in hospital by telemetry and on discharge using a handheld thumb ECG device three times a day, and thereafter for 2-week periods at 3, 12 and 24 months. The primary endpoint was the cumulative incidence of new-onset atrial fibrillation 24 months after the index procedure. Secondary objectives were to describe the incidence of cerebral ischaemic stroke and bleeding, myocardial infarction and major bleeding events during 24 months follow-up.
Mean age was 67 years, and male sex was more prevalent. At 30 days, the cumulative incidence of atrial fibrillation was 56% (69/123) in the coronary artery bypass graft group and 2% (3/123) in the percutaneous coronary intervention group. At 24 months, the cumulative incidence of atrial fibrillation was 58% (71/123) in the coronary artery bypass graft group and 6% (7/123) in the percutaneous coronary intervention group. Stroke, myocardial infarction and major bleeding were infrequent during follow-up.
Over 24 months of follow-up, incident new-onset atrial fibrillation mainly occurred during the first 30 days after coronary artery bypass grafting but was more evenly distributed during 24 months after percutaneous coronary intervention.

BackgroundThe role of early enteral nutrition (EEN) in septic shock remains unclear. This study aimed to evaluate the association between EEN and clinical outcomes in septic patients requiring vasopressor therapy and invasive mechanical ventilation.
MethodsThis retrospective cohort study used the MIMIC-IV database and included adult septic patients receiving vasopressors and mechanical ventilation at ICU admission. EEN was defined as enteral nutrition initiated within 48 hours. The primary outcome was 28-day mortality. Secondary outcomes included ICU and hospital length of stay, and duration of mechanical ventilation. Inverse probability of treatment weighting (IPTW) was used to adjust for baseline confounders. Vasopressor dose was stratified based on the maximum norepinephrine-equivalent dose in the first 48 hours: low (0.5). Multivariable regression models were used to assess associations.
ResultsA total of 4,673 patients were included, of whom 997 (21.3%) received EEN. Before weighting, EEN was associated with higher 28-day mortality (21.9% vs. 15.3%). After IPTW adjustment, early feeding remained significantly associated with increased mortality (adjusted odds ratio 1.80; 95% confidence interval, 1.42 to 2.27). In stratified analyses, EEN was associated with increased mortality in the medium-dose (odds ratio 1.66; 95% confidence interval, 1.26 to 2.19, p Conclusions
In critically ill septic patients receiving vasopressors and mechanical ventilation, EEN was associated with increased 28-day mortality, particularly among those receiving medium- or high-dose vasopressor therapy.

Previous studies have demonstrated that emotional facial expressions influence attention and perception in individuals with social anxiety. However, the relative influence of positive versus negative expressions on distinct subprocesses of attention and perception remains unclear. This event-related potential (ERP) study investigates the temporal dynamics of electrophysiological responses to emotional faces in high (HSA; N = 56) or low (LSA; N = 47) social anxiety individuals using a dot-probe task. Four face pairs (angry-neutral, happy-neutral, angry-happy, and neutral-neutral) were presented to probe the influence of positive and negative expressions. While behavioural results showed no significant group differences in attention bias, ERP results showed a reduced N170 amplitude for the HSA vs. LSA group in angry-neutral, happy-neutral, and angry-happy face pairs. Furthermore, enhanced N2pc effects to emotional expressions were found only in the HSA group when angry-neutral and happy-neutral face pairs were presented. No N2pc effect emerged when both positive and negative expressions were presented simultaneously. Finally, no significant P1 effect was found. Together, both positive and negative expressions influenced attentional deployment and face-specific processing in relation to social anxiety. Socially anxious individuals perceived less emotional facial information, yet their attention was biased by both negative and positive expressions.The decline in intrinsic capacity (IC) among older adults poses significant challenges to healthy ageing. Despite the importance of self-management in enhancing IC, research on self-management patterns and their predictors among older adults with declined IC remains limited.
This study aimed to explore clusters of self-management behaviours and their predictors among older adults with declined IC using an integrated theoretical framework combining the Theory of Planned Behaviour (TPB) and the Health Action Process Approach (HAPA).
This cross-sectional study was conducted in two community health centres in China from December 2022 to June 2023. A convenience sample of 308 older adults with declined intrinsic capacity was recruited based on WHO-recommended criteria. Self-management behaviours were assessed using the Chronic Disease Self-Management Behaviour Scale. HAPA constructs (self-efficacy, outcome expectancy, risk perception, planning) and TPB constructs (subjective norms, behavioural attitudes, perceived behavioural control, behavioural intention) were measured via validated questionnaires refined through expert consultation. Unsupervised k-means clustering was applied to identify behavioural subgroups, validated by principal component analysis. Inter-subgroup differences were examined using Analysis of Variance (ANOVA) or rank-sum tests for continuous variables and chi-square tests for categorical variables.
Three distinct self-management behaviour subgroups were identified among older adults with declined intrinsic capacity: Hesitant to Act (n=196), Norm-Dependent (n=42) and Assertive Decisiveness (n=70). Significant differences were observed across subgroups in demographic characteristics, including gender (p=0.017) and education (p=0.005), as well as in HAPA/TPB construct scores, including perceived behavioural control and planning (all p
This study identifies three distinct patterns of self-management behaviours among older adults with declined IC. The findings highlight the need for tailored interventions targeting the specific challenges faced by each subgroup. Future research should validate these findings in larger samples and explore causal relationships between variables.
Adolescent idiopathic scoliosis (AIS) involves three-dimensional structural spinal changes, frequently accompanied by scapular dyskinesis (SD) and proprioceptive dysfunction. Although physiotherapeutic scoliosis-specific exercises effectively correct spinal alignment, their efficacy in addressing SD and associated sensorimotor deficits remains underexplored. This randomised controlled trial (RCT) will evaluate whether integrating upper limb proprioceptive neuromuscular facilitation (PNF) with conventional physical therapy yields synergistic improvements in scapular kinematics and proprioceptive function in AIS.
This single-centre RCT will be conducted at the Department of Rehabilitation Medicine, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. 48 adolescents with AIS will be randomly assigned to either a control group (n=24) receiving conventional physical therapy or an experimental group (n=24) receiving combined conventional therapy and upper limb PNF interventions. Both groups will follow a structured 60 min rehabilitation programme, administered five sessions per week for 8 weeks (including two outpatient sessions and three home training sessions per week). Follow-up assessments will be conducted at 12 weeks postintervention to evaluate the maintenance of therapeutic effects. Primary outcomes will include the scapular balance angle and the active relocation test for shoulder proprioception. Secondary outcomes will comprise the scapular index, the lateral scapular slide test, normalised surface electromyography (root mean square, %muscle activation degree) of the upper trapezius, lower trapezius, serratus anterior, posterior deltoid and infraspinatus during standardised tasks, posture analysis, Cobb angle, angle of trunk rotation and the Simplified Chinese version of the Scoliosis Research Society-22 questionnaire for health-related quality of life. Data will be analysed using Analysis of Covariance and linear mixed-effects models, adjusted for baseline values, following the intention-to-treat principle.
The study protocol has been approved by the Ethics Committee of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology (Approval No. TJ-IEB2025-018) and has been registered on ClinicalTrials.gov. The findings will be disseminated through peer-reviewed journal publications, conference presentations and media releases.

To examine how gender differences in the nursing work environment shape nurses' perceived quality of care and to identify gender-specific predictors and evaluative mechanisms.
A mixed-methods design was employed, integrating quantitative data analysis with qualitative in-depth individual interviews.
This study was conducted in two phases: The first phase was a quantitative analysis, based on a large national dataset from the 2017 Chinese Nursing Work Environment Survey (N = 16,382), in which secondary analysis was performed using hierarchical linear regression, relative importance analysis, and network analysis to identify key predictors. The second phase was a qualitative study, in which in-depth individual interviews were conducted with 30 clinical nurses (15 male and 15 female), and thematic analysis was applied to explore gender-differentiated experiences.
The core finding of this study is that gender-differentiated factors within the work environment significantly shape nurses' perception of care quality. Quantitative results showed that the strongest predictor for female nurses was professional development, whereas recognition of value was most salient for male nurses. Qualitative results corroborated these findings: female nurses emphasised continuing education and emotional support, while male nurses emphasised fair evaluation and professional identity. Both groups reported that high-intensity workloads hindered the delivery of ideal humanistic care, inducing moral distress and emotional suppression and exposing ethical gaps in organisational support.
Gender differences in the nursing work environment shape pathways to perceived care quality and expose deeper managerial and ethical challenges. A gender-sensitive, ethics-oriented management approach can enhance nurse satisfaction and care quality, providing empirical support for optimising workforce allocation and sustaining healthcare systems.
Findings direct nurse leaders to tailor improvement strategies—enhancing professional-development infrastructure for women and strengthening recognition mechanisms for men—while embedding explicit ethical support to reduce moral distress and improve both workforce well-being and patient outcomes.

Irritant contact dermatitis is a common peristomal skin complication. Due to the continuous irritation from intestinal fluids and faeces, the healing of this dermatitis is slow and the condition severely impairs patients' quality of life. The study aimed to evaluate the efficacy of a modified insertable ostomy appliance in promoting healing and improving patient outcomes. A randomised controlled trial was conducted from January 2022 to December 2024 in a tertiary hospital. The enrolled patients, all diagnosed with irritant contact dermatitis, were randomly assigned to two groups. The control group wore the conventional two-piece ostomy appliance, while the experimental group wore the modified insertable ostomy appliance. Outcomes were assessed on Days 3, 7, 14 and 28. The primary outcome was the healing rate (Discoloration, Erosion and Tissue overgrowth [DET] score ≤ 2) at Day 28. Secondary outcomes included the DET score, Visual Analogue Scale (VAS) pain score, Stoma Quality of Life questionnaire (Stoma-QOL) score and the incidence of appliance leakage. A total of 89 eligible participants completed the trial. The experimental group showed a significantly higher 28-day healing rate (73.3% vs. 29.5%, p < 0.001), lower DET scores (Day 28: 2.0 vs. 4.5, p < 0.001), reduced VAS scores (Day 28: 1.5 vs. 2.0, p < 0.001), higher Stoma-QOL scores (Day 28: 55.67 vs. 51.64, p < 0.001) and lower leakage rate (13.3% vs. 93.2%, p < 0.001). The modified ostomy appliance significantly improves healing, reduces pain and enhances quality of life, representing a novel solution for clinical practice.

Perfluorinated compounds (PFCs) are persistent environmental pollutants with near-universal human exposure, yet their respiratory health impacts during adolescence remain insufficiently explored. This investigation evaluated single and combined effects of serum PFCs on pulmonary function and respiratory morbidity in a nationally representative adolescent cohort (n = 976, ages 12–19 years) utilizing 2007–2012 NHANES data. Advanced analytical approaches including multivariable regression, mixture modeling (BKMR and WQS), and mediation analysis were employed to assess associations with spirometric parameters (FEV1, FVC, FEV1/FVC) and respiratory symptoms while examining inflammatory and oxidative stress pathways. Computational approaches integrating network toxicology and molecular docking identified key protein targets. Analytical results demonstrated significant associations between specific PFC congeners (PFOA, PFHS, PFOS) and pulmonary function measures, with age-stratified effects observed for wheezing symptoms. Mixture analyses revealed PFOA as the predominant contributor to observed respiratory effects, partially mediated through oxidative stress pathways (6.8–8.2% mediation). Molecular investigations identified critical signaling nodes (INS, AKT1, TP53, TNF, IL6, ALB and PPARγ) potentially linking PFC exposure to respiratory outcomes. These findings provide mechanistic insights into PFC-induced pulmonary effects during adolescence, highlighting the need for continued investigation of these environmentally persistent compounds’ impact on developing respiratory systems. The integrated epidemiological-computational approach demonstrates the utility of combining population-level data with mechanistic modeling to elucidate environmental health effects.This study aims to investigate whether higher levels of depression predict increased physical frailty over time and whether worsening physical frailty predicts higher levels of depression over time, at both the between-person and within-person levels.
A longitudinal study.
A total of 269 patients who underwent cardiac surgery were included in this study at T1 (admission). We followed up depression and physical frailty at T2 (the seventh day after surgery), T3 (the day before discharge), and T4 (the three-month follow-up). To determine the temporal order of the association between depression and physical frailty at both between-person or within-person levels, we employed the cross-lagged panel model (between-person effects), and random intercept cross-lagged panel model (within-person effects).
The cross-lagged panel model findings revealed a time-dependent shift in directionality: physical frailty initially predicted depression between T1 and T2, whereas depression subsequently emerged as a significant predictor of physical frailty from T2 to T4. These between-person effects suggest that the dominant direction of influence may vary across different perioperative stages. Notably, the random intercept cross-lagged panel model results identified a robust unidirectional within-person effect, indicating that increases in depression consistently predicted subsequent increases in physical frailty over time, while the reverse pathway was not statistically significant. This finding underscores the potential causal role of depression in driving physical frailty progression, beyond the influence of stable between-person characteristics.
This study advances understanding of the depression-physical frailty relationship in middle-aged and older cardiac surgery patients by delineating temporal precedence and disentangling within- and between-person effects. Depression emerges as a key driver of physical frailty, underscoring the need to prioritize its management in postoperative care protocols. Future research should explore mechanisms linking intraindividual depression to physical frailty progression and evaluate integrated psychosomatic interventions to optimize recovery outcomes.
We have adhered to the STROBE guideline.

Coronary endarterectomy (CE) combined with coronary artery bypass grafting (CABG) has been associated with poor graft patency, which might be attributed to the activation of coagulation cascade caused by the exposure of the subendothelial tissue to the blood stream, which could necessitate anticoagulation therapy. However, the optimal antithrombotic therapy after CE+CABG remains unclear.
The PATH-CARE is a double-centre, two-armed, blinded to outcome assessed, randomised controlled trial, aimed to determine the optimal antithrombotic therapy after CE+CABG. A total of 202 patients are expected to be recruited. Patients will be randomly assigned in a 1:1 ratio to the control (dual antiplatelet therapy (AT) group) and the intervention (dual AT+warfarin (ATW) group). Patients in the AT group will receive aspirin plus clopidogrel for 1 year, while patients in the ATW group receive aspirin plus clopidogrel for 1 year with extra warfarin therapy for the first 3 months postoperatively. All patients will receive life-long aspirin treatment after the first year. All of the patients will be required to complete a 6-month follow-up.
