Objective:To explore the effectiveness of generative artificial intelligence (GAI) -empowered interprofessional collaborative learning model in nursing psychology practical teaching for undergraduate nursing students.Methods:From November to December 2024, 109 second-year nursing students from the Xiangya School of Nursing, Central South University were selected as research subjects using convenience sampling. Two classes were randomly divided into an experimental group (55 students) and a control group (54 students) using a random draw method. Control group received a traditional teaching model based primarily on case discussion and scenario simulation teaching, while experimental group used the GAI-empowered interprofessional collaborative learning model on the basis of control group. The teaching effectiveness was evaluated using the Psychological Nursing Practice Competency Assessment Scale, Caring Ability Inventory (CAI), Readiness for Interprofessional Learning Scale (RIPLS), and Satisfaction Survey Questionnaire.Results:After teaching, experimental group's practical course assessment scores, CAI total scores, and scores in each dimension were all higher than those of control group, with statistically significant differences ( P<0.01). The RIPLS score of nursing students in experimental group after teaching was higher than that before teaching, and the difference was statistically significant ( P<0.01). 90.9% of nursing students supported the introduction of GAI into the classroom, and 90.9% of nursing students recognized the auxiliary role of GAI in achieving learning objectives, and the teaching satisfaction was 96.4%. Conclusions:This study validates the effectiveness of GAI-empowered interprofessional collaborative learning model in nursing psychology practical teaching for undergraduate nursing students, providing new ideas for nursing education reform.

Objective:To conduct a scoping review of the related research on the maternal-fetal attachment in pregnant women after assisted reproductive technology (ART), summarize the research status of maternal-fetal attachment, and provide reference for future research prospects.Methods:A search was conducted for studies published in PubMed, Embase, EBSCO, Web of Science, Scopus, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and Chinese Medical Journal Full-text Database, from the date of database construction to January 24, 2024. The results of the literature were screened, extracted, and summarized.Results:A total of 15 studies were included. Among them, 14 observational studies reported that the overall status of maternal-fetal attachment of ART pregnant women was in good condition, but the data sources of domestic research were insufficient. Three evaluation tools were used in 15 articles. The related factors were summarized as demographic factors (age and personality traits), pregnancy-related factors (such as conception method, gestational age, history of infertility, history of miscarriage, etc), and psychosocial factors (such as anxiety, depression, conflicts, attitudes towards childbirth, acceptance of pregnancy, social support, marital satisfaction, etc). Four studies put forward suggestions or conducted intervention studies on improving maternal-fetal attachment of ART pregnant women.Conclusions:There is a lack of attention to the maternal-fetal attachment of ART pregnant women in China. Due to the complexity and diversity of its influencing factors, we should deeply explore the characteristics of maternal-fetal attachment development of ART pregnant women at all stages of pregnancy, and carry out more high-quality research. At the same time, we should pay attention to and carry out early screening of maternal-fetal attachment disorders, formulate targeted interventions, so as to promote the establishment of high-quality maternal-fetal attachment, and lay a solid foundation for future maternal-infant relationships.

Among them, there were 3 guidelines, 6 expert consensuses, 3 clinical decisions, 2 quasi-experiments, and 1 systematic review. Thirty pieces of evidence were summarized from five aspects: assessment, education and publicity, preparation before examination, detection during examination, care after examination.Conclusions:The best evidence for the nursing management of patent foramen ovale detected by cTEE is of high quality and strong authority, which can provide evidence-based basis for standardizing clinical practice and accurately and efficiently detecting patent foramen ovale.

Objective:To investigate the current status and influencing factors of decision anxiety in guardians of children with acute appendicitis under Endoscopic retrograde appendicitis therapy (ERAT) background, and to provide reference for the development of targeted intervention programs for decision anxiety.Methods:Convenient sampling method was used to select 254 guardians of children with acute appendicitis treated in the Department of Pediatrics, Second Affiliated Hospital of PLA Air Force Medical University from February 2023 to April 2024. A cross-sectional survey was conducted using the General Data Questionnaire, the State-Trait Anxiety Inventory Form Y-State anxiety subscale and the Preparation for Decision Making Scale. Multiple linear regression was used to analyze the influencing factors in guardians of children with acute appendicitis.Results:Among the guardians of 254 children with acute appendicitis, 156 were males and 98 were females, aged (37.44 ± 3.63) years old. The decision anxiety score of guardians of children with acute appendicitis was (52.49 ± 6.54). The results of multiple linear regression showed that age of children, gender of guardian, education level of guardian, per capita monthly income of family, decision making tendency and decision preparation were the main influencing factors of decision anxiety in guardians of children with acute appendicitis ( t values were -7.07-3.58, all P<0.05), which could explain 64.4% of the total variation. Conclusions:The decision anxiety in guardians of children with acute appendicitis is at a high level. Medical staff should provide targeted decision guidance, improve decision assistance programs and provide more effective decision support for guardians of children with acute appendicitis.

Objective:To construct a device-related pressure injury prevention program for orthopedic patients based on evidence-based and SSKINS (S: skin, S: surface, K: keep moving, I: incontinence, N: nutrition, S: self-care) clinical management model, and to provide reference for clinical nursing practice.Methods:In June 2023, a research team was set up to retrieve the literature related to device-related pressure injury in orthopedic patients, and the evidence was extracted and screened with reference to the SSKINS clinical management model, and the first draft of the protocol was formulated based on clinical practice. The final plan was determined through two rounds of expert consultations from October to December 2023.Results:The response rate of the two rounds of expert correspondence was 100%(20/20). The expert authority coefficients were 0.897 and 0.907, the overall Kendall coordination coefficients of the two rounds were 0.116 and 0.136 respectively, and the Kendall coordination coefficients of all levels were 0.104-0.213 (all P<0.001). The final protocol contains 6 first-level items (assessment and examination, the use and adjustment of device, prophylactic dressings, skin protection, nutritional support, health education) and 31 second-level items. Conclusions:The proposed orthopedic device-related pressure injury prevention program is scientific and practical, and can provide a reference for the prevention and management of clinical medical staff.

Objective:To construct a predictive model for postoperative delirium (POD) in patients undergoing gastrointestinal surgery using machine learning.Methods:This retrospective study used clinical data from patients who underwent gastrointestinal surgery at Subei People′s Hospital between September 2022 and April 2024. The entire dataset was randomly divided into the training and validation sets in an 8∶2 ratio. Multivariate logistic regression analysis was conducted to identify the factors influencing POD. Eleven machine learning models were established and compared. The performance of the models was validated using metrics, including accuracy, precision, recall, Youden′s index, F1 score, Matthews′ correlation coefficient, Kappa coefficient, log loss, and Brier score. Receiver operating characteristic and calibration curves were plotted to assess the discrimination and consistency of the model. Shapley additive explanations were used in Python for interpretative analysis of the model with the best predictive performance, and the importance of the feature parameters was ranked.Results:A total of 1, 785 patients were ultimately included, of which 833 (46.67%) experienced POD. The results of multivariate logistic regression analysis revealed that advanced age, lower preoperative serum calcium ion concentration, postoperative pulmonary infection, and higher preoperative systolic blood pressure were independent risk factors for POD in patients undergoing gastrointestinal surgery, while laparoscopic surgery was a protective factor ( P<0.05). Among the 11 machine learning models, the categorical feature gradient boosting model exhibited the best performance, with an area under the receiver operating characteristic curve of 0.82 (95% confidence interval 0.77-0.87). The ranking of feature importance indicated that age had the greatest contribution in predicting POD. Conclusions:The predictive model for POD established based on the categorical boosting algorithm has higher predictive efficacy and clinical application value in patients undergoing gastrointestinal surgery.

Objective To investigate the effects and mechanisms of Huatan Quyu Decoction on learning and memory abilities in rats with vascular dementia(VD).Methods Totally 112 male SD rats were randomly selected with 16 rats as the sham-operation group,the remaining rats were used to prepare VD models by segmental ligation of the common carotid artery.The successfully modeled rats were randomly divided into model group,Huatan Quyu Decoction low-,medium-and high-dosage groups(6.1,12.1,24.2 g/kg),donepezil hydrochloride group(0.5 mg/kg)and combination group(Huatan Quyu Decoction 12.1 g/kg+donepezil hydrochloride 0.5 mg/kg),with 16 rats in each group.Each group was given the corresponding treatment measures for 4 weeks.The Morris water maze test was used to assess learning and memory abilities,neurological function was evaluated using Garcia score,HE staining was used to observe the morphology of the hippocampal tissue,ELISA was employed to detect the serum content of Aβ,immunohistochemistry was utilized to observe the β-catenin,LRP6 and GSK-3β protein expression in brain tissue.Results Compared with the sham-operation group,the escape latency of the model group rats was prolonged(P<0.01),the number of crossing platforms was reduced(P<0.01),and the neurological deficit score was decreased(P<0.01),the arrangement of hippocampal tissue cells was disorderly,and the tissue was severely damaged,the serum Aβ content increased(P<0.01),the expressions of β-catenin and LRP6 protein in brain tissue decreased,and the expression of GSK-3β protein increased(P<0.01).Compared with the model group,the escape latency of rats in each administration group was shortened,the number of crossing platforms increased,the neurological deficit score increased,the number of hippocampal cells was relatively more,the arrangement was more orderly,and the structure was relatively complete,the serum Aβ content decreased,the expressions of β-catenin and LRP6 proteins increased,and the expression of GSK-3β protein decreased.Among them,Huatan Quyu Decoction high-dosage group had a significantly better effect than Huatan Quyu Decoction low-and medium-dosage groups(P<0.01),and there was no statistical significance in various indicators compared with the donepezil hydrochloride group(P>0.05).Compared with the donepezil hydrochloride group,the combination group showed significant improvements in learning and memory abilities(P<0.01),the neurological deficit score significantly increased(P<0.01),the number of hippocampal cells significantly increased,arranged neatly,and structurally intact,the serum Aβ content significantly decreased(P<0.01),the expression of β-catenin and LRP6 proteins significantly increased,and the expression of GSK-3β protein significantly decreased(P<0.01).Conclusion Huatan Quyu Decoction can repair cognitive function in VD rats,improve learning and memory abilities,and alleviate VD symptoms by activating the Wnt/β-catenin signaling pathway to reduce serum Aβ content,decrease the apoptosis of nerve cells and alleviate the degree of pathological damage in hippocampal tissue.
