ObjectiveAdenosquamous carcinoma (ASC) of the lung, containing both adenocarcinoma (AC) and squamous cell carcinoma (SCC) components, is associated with aggressive behavior and poor prognosis. Due to overlapping imaging features with AC and SCC, its preoperative diagnosis remains challenging. This study aimed to compare CT and pathological characteristics among ASC, AC, and SCC; identify key differentiators.
MethodsThis retrospective study included 27 patients with pathologically confirmed ASC who underwent surgical resection from November 2018 to January 2025. Forty cases each of AC and SCC, matched for age, sex, and smoking history, were selected for comparison. Clinical, radiological, and pathological features were analyzed. Variables with statistical significance (P Results
Compared with SCC, ASC lesions were more peripheral and associated with higher distance ratios (DR), pleural retraction, spiculation, and lymph node metastasis (LNM). Compared with AC, ASC tumors were larger, more often solid, and exhibited lobulation, bronchial cutoff sign, and advanced staging. Among the evaluated analyses, the combined pathology–imaging approach showed the highest discriminatory performance, with AUCs of 0.909 (ASC vs SCC) and 0.900 (ASC vs AC). LNM and DR were more strongly associated with ASC relative to SCC, whereas larger tumor size, ill-defined margins, and advanced stage were more strongly associated with ASC relative to AC.
ConclusionCertain CT imaging features, especially DR and LNM, were associated with ASC and may provide useful information for preoperative radiological assessment and subtype stratification.
The study examines the associations between nursing competence, work environment, and health system resilience. It also analyzes how nursing competence and work environment relate to different patterns of health system resilience.
A multiple center cross-sectional study was conducted between December 2023 and January 2024 across 33 hospitals in eastern China, involving 2435 nurses.
Questionnaires measuring nursing competence, work environment resources, nurse disaster resilience, and organizational commitment to resilience were utilised, along with the collection of additional personal demographic data. Structural equation modelling and cluster analysis were performed to explore the underlying mechanisms within the overall model and across multiple groups. Multivariable regression was conducted to identify variables associated with resilience in different subgroups.
Structural equation modelling demonstrated significant influences of nursing competence and work environment support on system resilience. Cluster analysis identified four resilience patterns: strong, marginal, low, and critical vulnerability. Strong resilience correlated with balanced individual-organizational resources, while vulnerable systems relied heavily on environmental support.
Our findings support policymakers and managers in developing systematic strategies with distinct focal points—targeting nurse workforce investment and optimised work environment—to enhance health system resilience across varying levels of public health emergencies.
This study validated the framework connecting individual and organizational resilience, offering evidence-based insights for nurse training and resource allocation to enhance healthcare systems' adaptability during disasters.
The study addressed how nursing competence and work environment significantly influenced resilience during public health emergencies, identified four resilience patterns, and provided insights to guide policymakers and healthcare managers in developing targeted, effective strategies.

The global nursing shortage poses a critical challenge to healthcare systems. Emergency department (ED) nurses face high occupational stress due to demanding environments and strained patient-family interactions. Chronic stress impairs resilience and health, contributing to burnout and attrition. Understanding ED nurses' stressors and resilience is vital for workforce stability.
To identify core elements and interrelationships of occupational stressors and resilience among ED nurses in Zhejiang Province, China, using network analysis, and to explore intervention strategies.
Cross-sectional study.
From November 2024 to January 2025, data were collected from 990 ED nurses in 26 hospitals across 11 cities. Measures included a demographic questionnaire, the Chinese version of the Stressor Scale of Emergency Nurses, and the Resilience Structure Scale for Healthcare Professionals. Network analysis was conducted to illustrate the interconnections between stressors and resilience factors, while accounting for significant sociodemographic covariates.
A total of 990 nurses participated in the study. Violence-related stressors, such as physical assault and witnessing aggression, were the most prominent nodes in the stressor network. Key resilience elements included reframing patient or family criticism positively and timely emotional regulation. Bridge analysis highlighted ‘viewing criticism as encouragement’ as a crucial link connecting stress and resilience.
ED nurses work under intense stress from violence and scrutiny, which undermines resilience. Strengthening key resilience factors—especially cognitive reframing and emotional regulation—may buffer stress and enhance coping. Bridge nodes offer targeted points for intervention.
None.
This study clarifies the network of occupational stressors and resilience in ED nurses, identifying key intervention targets. It supports interventions focusing on cognitive adjustment, emotional regulation and interpersonal support to build resilience and reduce stress.
