Objective:To analyze the association between healthcare workers mental health,institu-tional supplies and facilities,inter-organizational coordination during infectious disease outbreaks,and the healthcare institution resilience.Methods:An online questionnaire survey was conducted among the healthcare workforce from 146 institutions in Beijing from January 13,2023 to February 9,2023,and a total of 1 434 eligible respondents were included.The sample comprised 408 responses from tertiary hos-pitals,117 from secondary hospitals,and 909 from primary care institutions.The resilience indicator for healthcare institutions was defined as the degree to which medical services met patient demands,with in-fluencing factors including physical factors,such as material shortages and facility space adaptation or ex-pansion,organizational factors such as information sharing and patient referral,and psychological factors were evaluated using job satisfaction(extrinsic satisfaction,intrinsic satisfaction),burnout(emotional exhaustion,depersonalization,reduced personal accomplishment),and depression status.Ordered mul-ticlassification Logistic regression was used to examine the impact of various factors on the degree to which healthcare services met patient needs;additionally,demographic factors that might influence institutional resilience were controlled.Results:During the emergency response phase,93%of hospitals maintained the capacity to meet patient needs,though tertiary hospitals demonstrated significantly higher rates of service inadequacy(21.05%).Material shortages were reported across all institutions,with tertiary hos-pitals experiencing more frequent multi-item shortages.Inter-institutional collaboration patterns revealed substantial variation:87.50%of primary care facilities,42.86%of secondary hospitals,and 31.58%of tertiary hospitals.Healthcare workers across all levels reported mild depressive symptoms and moderate-to-severe burnout levels.Regression analysis showed high satisfaction(overall satisfaction β=0.04,ex-trinsic satisfaction β=0.06,and intrinsic satisfaction β=0.08),low degree of job burnout(emotional exhaustion β=-0.04,depersonalization β=-0.07 and reduced personal accomplishment β=0.01),low degree of depression(β=-0.06)were significantly associated with higher healthcare institution re-silience.In addition,material shortages were significantly associated with lower resilience,and renova-tion and expansion of treatment spaces,and information sharing,were all associated with higher resilience.Demographic factors(age,gender,marital status,educational background,etc.)had no sig-nificant impact on resilience.Conclusion:Mental health status significantly influences healthcare institu-tion resilience.As human resources constitute the core asset of healthcare institutions,strategic optimiza-tion of workforce allocation and psychological support interventions can effectively strengthen resilience.Moreover,healthcare institution resilience is positively impacted by orderly material supply chains,timely resource distribution,and adaptive reconfiguration of clinical spaces.Finally,facilitating information sharing also enhances institutional resilience.

Objective:To analyze the evaluation value of contrast-enhanced ultrasound (CEUS) combined with automatic volumetric ultrasound in the efficacy of neoadjuvant chemotherapy (NAC) for breast cancer.Methods:A retrospective study was conducted on 98 female patients with breast cancer admitted to Shaanxi Provincial Cancer Hospital from January to December 2022. All patients received 4 cycles of NAC, and underwent conventional ultrasound, automatic volumetric ultrasound, CEUS, and histopathological examination before and after treatment. Based on the post-treatment histopathological efficacy, patients were divided into the effective group ( n=67) and the ineffective group ( n=31). The CEUS and automatic volumetric ultrasound parameters before and after treatment, as well as the evaluation efficacy of these two types of parameters for NAC efficacy in breast cancer, were compared. The value of CEUS combined with automatic volumetric ultrasound in evaluating NAC efficacy for breast cancer was analyzed. Results:After NAC treatment, the CEUS parameters [time to peak (TTP) and arrival time (AT) of contrast agent] were longer than those before treatment, while the peak intensity (PI) was lower than that before treatment (all P<0.05); the automatic volumetric ultrasound parameters (tumor volume, area, thickness, length, and width) after NAC treatment were all smaller than those before treatment (all P<0.05). After treatment, the PI, volume, area, thickness, length, and width in the effective group were significantly smaller than those in the ineffective group, while the TTP and AT were significantly longer than those in the ineffective group (all P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of CEUS parameters and automatic volumetric ultrasound parameters for predicting effective NAC efficacy in breast cancer was 0.837(0.749-0.904) and 0.864(0.780-0.925), respectively, with no statistically significant difference between the two ( P=0.674). The AUC of the combined parameters for predicting effective NAC efficacy was 0.942(0.875-0.979), which was significantly higher than that of CEUS parameters or automatic volumetric ultrasound parameters alone ( Z=2.947, 2.135, P=0.003, 0.033). Conclusions:The combination of CEUS and automatic volumetric ultrasound parameters has high value in the efficacy evaluation of NAC for breast cancer and can be used as a clinical reference.

Objective:To investigate and validate the performance of a dosiomics model that utilized 3D dose distribution to forecast radiation-induced temporal lobe injury (RTLI) in nasopharyngeal carcinoma (NPC) patients following intensity-modulated radiotherapy (IMRT).Methods:Clinical data of 3578 patients diagnosed with NPC admitted to Jiangsu Cancer Hospital from January 2011 to December 2021 were retrospectively analyzed. According to the inclusion and exclusion criteria, 97 NPC patients who developed RTLI were assigned into the case group. A 1:1 propensity score matching (PSM) method was used to match 97 NPC patients without RTLI as the control group. Patients were assigned into the training cohort ( n=135) and the validation cohort ( n=59) at a 7:3 ratio by simple random method. Dosiomics features were extracted from the patients' three-dimensional dose distribution maps. Spearman rho and the least absolute shrinkage and selection operator regression were used to select dosiomics features. Clinical features were collected and screened by univariate and multivariate analyses. Eight machine learning classifiers were then trained to build dosiomics models and clinical models, respectively. The area under the ROC curve (AUC), sensitivity, and specificity were calculated to compare the predictive performance of the dosiomics and clinical models. Multivariate analysis was conducted using logistic regression to assess the influencing factors, while comparisons of the ROC curves between two different models were performed using the DeLong test. Results:A total of 1130 dosiomics features were extracted from the three-dimensional dose distribution maps, and 14 features were retained for model building after feature selection. The model based on the support vector machine (SVM) classifier achieved the highest AUC value of 0.977 (95% CI: 0.949-1.000) in the validation cohort, with an AUC of 1.000 (95% CI: 1.000-1.000) in the training cohort. By conducting univariate and multivariate analyses of the patients' clinical features, 2 clinical features were retained to build the clinical model. The model based on the SVM classifier achieved the optimal AUC value of 0.667 (95% CI: 0.523-0.810) in the validation cohort, with an AUC of 0.804 (95% CI: 0.730-0.878) in the training cohort. DeLong test showed that the difference between the dosiomics and clinical models was statistically significant ( P<0.05). Conclusion:The dosiomics model based on 3D dose distribution yields high predictive performance for RTLI in NPC patients after IMRT, which surpasses the clinical feature model, providing a new approach for early clinical prediction of RTLI.
