OBJECTIVE To confirm trigger items for adverse drug reaction （ADR） induced by bevacizumab， to identify and analyze the occurrence of related ADR， and to establish a predictive model for severe adverse reaction （SAR） caused by this drug. METHODS Based on the global trigger tool （GTT） theory， and referencing the GTT White Paper， drug package inserts and relevant literature， trigger items for bevacizumab-related ADR were confirmed using a single-round Delphi method. Utilizing these established items， electronic medical records of relevant patients at Guilin People’s Hospital from January 2020 to September 2024 were actively screened via the China Hospital Pharmacovigilance System. Pharmacists then identified and tallied the occurrence of bevacizumab-induced ADR. Data from patients with any positive trigger item served as the study subjects （divided into training and test sets at a ratio of 7∶3）， candidate feature variables were selected from 39 related variables using the Boruta algorithm， and the multivariable Logistic regression analysis was performed with the occurrence of SAR as the dependent variable. Based on these candidate features， Logistic Regression， Extreme Gradient Boosting， Light Gradient Boosting Machine， Random Forest， and Categorical Boosting models were constructed. Model performance was evaluated using metrics including the area under the curve （AUC） of receiver operating characteristic curve and recall rate. The Shapley Additive exPlanations （SHAP） method was applied to analyze and interpret the contribution of each variable. A nomogram was constructed based on the optimal model. RESULTS A total of 38 trigger items for active monitoring of bevacizumab-related ADR were determined， comprising 17 laboratory indicators， 13 clinical manifestations， and 8 intervention measures. In total， 483 patients with positive trigger items were included， and 318 patients with bevacizumab-induced ADR were identified， including 83 SARs. The positive predictive values for the trigger items and cases were 43.57% （708/1 625） and 63.84% （318/483）， respectively. Bevacizumab-induced ADR involved 7 systems/organs， with the hematological system being the most frequently involved （64.15%）. The Boruta algorithm selected 7 vari ables： serum potassium， hematocrit， albumin-to-globulin ratio， prealbumin， hypertension history， age and red blood cell count. Multivariable Logistic regression showed that elevated serum potassium levels were associated with a decreased risk of bevacizumab-induced SAR （OR＝0.234， P ＝0.002）， while a history of hypertension （OR＝2.642， P ＝0.006） and increased age （OR＝1.040， P ＝0.025） were associated with an increased risk. The Logistic Regression model demonstrated superior performance with higher AUC， F1 score and recall rate （0.761， 0.447， 0.607）， compared to other models. SHAP evaluation results indicated that variables such as serum potassium， hematocrit， and age ranked highest in importance. CONCLUSIONS Totally 38 trigger entries have been successfully identified for active screening of bevacizumab-related ADR. Elevated serum potassium levels are a protective factor against bevacizumab-induced SAR， whereas the hypertension history and increased age are risk factors. The Logistic Regression model is the optimal predictive model.

To summarize the nursing experience of a patient with chronic heart failure complicated with achalasia.The main nursing points were as follows:stabilizing electrolyte to correct malignant arrhythmia;providing stepped nutritional support based on swallowing function rating to improve nutritional status;acapella technology combined with micro-positive pressure high-flow oxygen therapy for airway clearance to control lung infection;implementing the whole process of psychological counseling to improve treatment confidence and compliance;formulating a systematic discharge preparation service plan to ensure continuous care.After careful care assisted by a multidisciplinary team,the patient was discharged smoothly after 13 days of hospitalization,followed up for 3 months,and recovered well.

OBJECTIVE To investigate the incidence of hospital-associated infections among the neurosurgery de-partment patients undergoing brain tumor resection and analyze the economic cost so as to provide scientific bases for formulating prevention strategies.METHODS Totally 1027 patients who underwent brain tumor resection in neurosurgery department of the First Affiliated Hospital of Shandong First Medical University from Jan.1,2020 to Dec.31,2024 were recruited as the research subjects.The 36 patients who had postoperative hos-pital-associated infections were assigned as the infection group,and 991 patients who did not have hospital-associ-ated infection were assigned as the no infection group.The patients of the infection group and the non-infection group were matched in a 1∶1 ratio by using propensity score matching method(caliper value 0.005).The length of hospital stay and costs of medical items were compared between the infection group and the non-infection group,and the economic burden due to the hospital-associated infections was estimated.RESULTS The incidence of hospital-associated infections was 3.51％among the patients undergoing brain tumor resection,and totally 36 pairs were matched successfully with the propensity score.The hospitalization cost of the infection group was 109,103.81(73,370.21,163,628.37)yuan after the matching,which was increased by 50,087.69 yuan as com-pared with the non-infection group(Z=-5.237,P＜0.001);the length of hospital stay was 23.00(17.25,36.00)days,which was prolonged by 8.50 days(Z=-3.764,P＜0.001).Among the costs of medical items,the medial costs of western medicine,treatment materials and clinical laboratory tests increased most.CONCLUSIONS The control of the costs of western medicine,treatment materials and clinical laboratory tests is the key to reduce the costs of brain tumor resection patients with hospital-associated infections.It is necessary to carry out the real-time monitoring of the hospital-associated infections and early warning of suspected cases and reduce the incidence of hospital-associated infections so as to reduce the economic costs.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective:To compare the efficacy and safety of extended-field versus reduced-field radiotherapy in upper tract urothelial carcinoma (UTUC) patients after radical operation.Methods:A retrospective analysis was conducted on the data of 210 UTUC patients who underwent full-length nephrectomy and received postoperative adjuvant radiotherapy in Peking University First Hospital from January 2013 to November 2023, and follow-up continued until June 2024. According to the target area of postoperative radiotherapy, patients were divided into the extended-field radiotherapy group (127 cases) and the reduced-field radiotherapy group (83 cases). The overall survival (OS), distant metastasis free survival (DMFS), local recurrence free survival (LRFS) and adverse reactions were compared. In the same period, 114 patients with recurrent abdominal and pelvic lymph nodes who did not receive adjuvant therapy after surgery for UTUC in our center were prospectively collected, and the coverage of the reduced-field target area was analyzed. Chi square test was used to compare the clinical characteristics, Kaplan-Meier method was used to analyze survival outcomes, log-rank test was used to compare the survival rate, and Cox multivariate regression analysis was performed on the influencing factors of survival.Results:The median follow-up was 24.5 (range: 3-74) months. There were no significant differences between the extended-field and reduced-field radiotherapy groups in terms of 2-year LRFS (93.3% vs. 98.1%, P=0.156), 2-year DMFS (84.8% vs. 91.2%, P=0.176), and 2-year OS (90.4% vs. 90.7%, P=0.707). The most common toxicities of adjuvant radiotherapy were nausea and leukopenia, with significantly higher grade 1-2 incidence in the extended-field group compared to the reduced-field group ( P<0.05). According to the analysis of patients with retroperitoneal lymph node recurrence after surgery, the reduced-field target designed according to the location of the primary tumor can cover more than 90% of the postoperative metastatic lymph node area Multivariate analysis revealed that variant histology ( HR=2.180,95% CI: 1.021-4.658, P=0.044) was an independent predictor of worse DMFS, while variant histology ( HR=3.825,95% CI: 1.514-9.662, P=0.005) and T 3-4 stage ( HR=4.452,95% CI: 1.025-19.339, P=0.046) were independent predictors of poorer OS. Conclusions:Compared with extended-field radiotherapy, reduced-field radiotherapy designed based on primary tumor location significantly reduced treatment-related toxicities without compromising postoperative therapeutic efficacy, and the reduced-field can cover more than 90% of local recurrent lesions.

Purpose To investigate the incidence and risk of malignancy(ROM)of the Bethesda class Ⅰ/Ⅲ di-agnosis of thyroid nodules due to insufficient number of follicular cells,and to analyze the correlation between their in-sufficient cell volume and the characteristics of the nodules themselves from the perspective of ultrasound and histology.Methods Clinical data were collected from fine needle aspiration cytology(FNAC)of the thyroid gland.Review and statistical analysis was performed on cases with the Bethesda class Ⅰ/Ⅲ diagnosis due to insufficient cell volume.The incidence and the ROM of Bethesda class Ⅰ/Ⅲ diagnosis were calculated.BRAF V600E(+)or postoperative patho-logical indicating papillary thyroid carcinoma(PTC)was used as the criterion for malignancy.Then,we matched the Bethesda class Ⅱ/Ⅵ cases with sufficient cell volume as the control group.The ultrasound characteristics and histo-logical images of the two groups were compared and analyzed in order to reveal the correlation between the insufficient amount of penetrating cells and the objective characteristics of the nodule itself.Results There were 39 solid thyroid nodules with the Bethesda class Ⅰ diagnosis,with an incidence of 3.3％and a ROM of 38.5％,and 160 nodules with the Bethesda class Ⅲ diagnosis,with an incidence of 13.5％and a ROM of 59.4％.The incidence and ROM of nod-ules with C-TIRADS ≥4b(22.4％,67.6％)were higher than those of C-TIRADS ≤4a(12.7％,39.8％),and the differences were statistically significant(P＜0.001).Compared to the Bethesda class Ⅱ/Ⅵ nodules with sufficient cell volume,occurrence of the Bethesda class Ⅰ/Ⅲ nodules were significantly correlated with small nodules(maximal diameter＜5 mm),vertical growth(aspect ratio ≥ 1)and poor blood supply(no or little blood flow signals)(r=0.131,-0.230,0.237,P=0.008,＜0.001,＜0.001).They were also significantly correlated with the pathologic histologic structure of diffuse significant fibrosis of the interstitium and low parenchyma/interstitium composition ratio(about 1:1)(r=-0.269,-0.396,P=0.019,＜0.001).Conclusion Thyroid Bethesda class Ⅰ/Ⅲ nodules have a high ROM,and BRAF V600E detection is recommended as a tool of tiered management.Bethesda class Ⅰ/Ⅲ diagnosis of insufficient cell volume is more likely when the nodules are too small,grow vertically and lack blood sup-ply,presumably associated with extensive interstitial fibrosis and sparse parenchymal cells.

Objective:To assess the level of moral distress among pediatric nurses in China and explore its influencing factors, providing a reference for future interventions.Methods:A cross-sectional survey was conducted using a convenience sampling method from May 2022 to March 2023. Pediatric nurses meeting the inclusion and exclusion criteria were selected from children′s specialized hospitals, general hospitals, and maternal and child health hospitals across 16 provinces in China. Moral distress was assessed using the Chinese version of the Moral Distress Scale-Revised (MDS-R). Data analysis included descriptive statistics, non-parametric analysis, and multiple linear regression.Results:A total of 509 pediatric nurses participated in the survey, including 10 males and 499 females. Among them, 45 were aged ≤25 years, 268 were aged 26-35 years, 172 were aged 36-45 years, and 24 were aged >45 years.The median moral distress score was 58.00 (26.00, 77.50). Factors independently associated with higher levels of moral distress included having a master′s degree ( t = 2.33), working in a ward with more than 40 beds ( t = 3.38), working in a ward without parental accompaniment ( t = 2.60), being passively assigned to the nursing profession ( t = 2.63), and considering resignation but not leaving the job ( t = 3.85) (all P<0.05). Conclusions:Pediatric nurses in China experience a moderate level of moral distress. Further research is needed to understand its underlying causes and to develop preventive and intervention strategies.
