Objective To investigate the effect of nursing intervention based on Kano model on surgical outcomes and negative emotions in patients with diabetic retinopathy(DR).Methods A to-tal of 262 DR patients who underwent vitrectomy were randomly divided into control group(n=131)and observation group(n=131)using the random number table method.The control group received routine nursing intervention,while the observation group received nursing intervention based on the Kano model.The surgical outcomes[visual acuity level and improvement in visual function],nursing needs[Perioperative Nursing Needs Questionnaire for DR Surgical Patients],negative emotions[Self-Rat-ing Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)],and quality of life[Chinese Version of Low Vision Quality of Life Scale(CLVQOL)]were compared between the two groups.The incidence of complications during the intervention period was also recorded in both groups.Results After interven-tion,the visual acuity levels in both groups increased compared to those before intervention,and the rates of low vision decreased(P＜0.001).The visual acuity level in the observation group was high-er,and the rate of low vision was lower than that in the control group,with statistically significant differences(P＜0.001).After intervention,the scores for peripheral visual field,sensory adaptation,and limitations in daily activities decreased in both groups compared to those before intervention,and the scores in the observation group were lower than those in the control group(P＜0.05).After intervention,the SAS and SDS scores in both groups decreased compared to those before interven-tion,and the scores in the observation group were lower than those in the control group(P＜0.001).After intervention,the CLVQOL scores in both groups increased compared to those before the intervention,and the score in the observation group was higher than that in the control group(P＜0.001).The incidence of complications in the control group was higher than that in the obser-vation group(12.22％versus 4.58％,P＜0.05).Conclusion Nursing intervention based on the Kano model can improve visual acuity level,visual function,and negative emotions,enhance the quality of life,and further reduce the incidence of complications in DR patients undergoing vitrectomy.

Objective To develop and validate risk prediction models utilizing five machine learning algorithms for assessing postoperative pulmonary infection(PPI)risk in lung cancer patients undergoing grade Ⅳ thoracoscopic surgery.Methods A retrospective cohort study included 2,380 lung cancer patients who underwent grade Ⅳ thoracoscopic surgery at a tertiary hospital in Shanghai(January 2022 to June 2024).Patients were stratified into training(n=1,665)and validation(n=715)cohorts.Five machine learning algorithms—Logistic regression(LR),artificial neural network(ANN),support vector machine(S VM),random forest(RF),and extreme gradient boosting(XGB)—were employed to construct predictive models.A nomogram was developed for clinical utility.Results Among 2,380 patients,226(9.5％)developed PPI.The Least Absolute Shrinkage and Se-lection Operator(LASSO)regression identified eight predictive variables:daily cigarette consumption,diabetes history,preoperative diffusing capacity,maximal tumor diameter,24-hour postoperative chest drainage volume,perioperative oral nutritional supplementation(ONS),postoperative urinary cathe-terization,and intraoperative pleural adhesion severity.All models demonstrated robust discrimina-tion,with area under the curve(AUC)values ranging from 0.862 to 0.947.The XGB model a-chieved superior performance(AUC=0.947,95％CI,0.937 to 0.962),followed closely by the LR model(AUC=0.926,95％CI,0.918 to 0.933).Conclusion Machine learning-based algo-rithms models effectively stratify PPI risk in lung cancer patients following grade Ⅳ thoracoscopic surgery.The derived nomogram provides a practical tool for perioperative risk management by healthcare providers.

Objective To conduct a multidimensional and multi-level evaluation of the comprehensive clinical value of empagliflozin in the treatment of type 2 diabetes mellitus.Methods Based on the National Essential Medicines List(2018 Edition),dapagliflozin was selected as the control.A comprehensive clinical evaluation index system was established through literature review,focus group interviews and in-depth expert interviews,encompassing six dimensions:safety,efficacy,economy,suitability,innovation,and accessibility.The Delphi method and hierarchical direct weighting method were used to screen indicators and determine their weights.Evidence for each indicator was collected and integrated both qualitatively and quantitatively through literature research,real-world studies,and pharmacoeconomic evaluations.Experts scored the indicators based on the collected evidence,and a total score for the comprehensive clinical evaluation of empagliflozin was calculated by combining these scores with indicator weights,followed by a comparative analysis with dapagliflozin.Results A comprehensive clinical evaluation of empagliflozin in the treatment of type 2 diabetes mellitus was successfully established,consisting of 6 primary indicators,14 secondary indicators,and 41 tertiary indicators.The overall evaluation score for empagliflozin was 90.35,and 89.47 for dapagliflozin.Conclusion The comprehensive clinical value of empagliflozin in the treatment of type 2 diabetes mellitus is slightly higher than that of dapagliflozin.This finding can serve as a reference for rational clinical drug use and related decision-making.

Objective To explore the application effect of team-based learning(TBL)teaching method combined with scenario simulation in the team-based cardiopulmonary resuscitation(CPR)training for standardized training of resident physicians in department of emergency.Methods A total of 86 standardized training resident physicians rotating in the department of emergency of Guangdong Provincial People's Hospital Southern Medical University from May 2022 to July 2023 were included as study subjects.These resident physicians were divided into a control group(n=42)and an observation group(n=44)according to different teaching methods.The control group was taught using the conventional teaching method,whereas the observation group was taught using a combination of TBL and scenario simulation-based method.The difference of theoretical assessment scores,practical skill competency and training satisfaction were compared before and after training between groups.Results The theoretical and practice skill assessment scores of both groups significantly improved after training(all P<0.05).However,there was no significant difference in the theoretical assessment scores or the score increase between the two groups before and after training.In the subcategory of theoretical assessment scores,the observation group had significantly higher points than the control group in the precautions category after training(21.09±2.07 vs.20.07±1.85,P<0.05).Compared with the control group,the observation group had significantly higher post-training practical skill scores and a significantly greater score increase(scores:86.77±3.89 vs.81.17±4.18,score increase:11±5.15 vs.8±4.60,both P<0.05).Among the subcategory practical skill scores,the observation group outperformed the control group in communication skills,emergency skills and teamwork+humanistic care(communication skills points:21.36±1.71 vs.20.07±1.54,emergency skills points:21.73±1.35 vs.20.21±1.79,teamwork+humanistic care points:22.27±1.76 vs.19.71±2.71,all P<0.05).The degree of satisfaction in overall training satisfaction,the novelty of the teaching method,teacher affinity,interests in learning,developing teamwork ability,class atmosphere,communication and expression ability,and confidence in skill mastery were significantly higher in the observation group than in the control group[overall training satisfaction:97.73%(43/44)vs.50.00%(21/42),the novelty of the teaching method:90.91%(40/44)vs.47.62%(20/42),teacher affinity:93.18%(41/44)vs.57.14%(24/42),interests in learning:97.73%(43/44)vs.59.52%(25/42),developing teamwork ability:95.45%(42/44)vs.52.38%(22/42),class atmosphere:93.18%(41/44)vs.57.14%(24/42),improve communication and expression ability:100.00%(44/44)vs.50.00%(21/42),and confidence in skill mastery:93.18%(41/44)vs.45.24%(19/42),all P<0.05].Conclusion The application of TBL teaching method combined with scenario simulation in CPR training for standardized training of resident physicians can effectively improve quality of clinical skill training.

Objective:To investigate the relationship between the weight-adjusted waist index(WWI)and acute,subacute pain or chronic pain among American adults.Methods:There was a cross-sectional study.Data from the 1999-2004 National Health and Nutrition Examination Survey(NHANES)con-cerning waist circumference,weight,pain status and covariates(age,gender,race,marital status,edu-cation level and income,physical activity,alcohol consumption,smoking status,and diabetes)were extracted for analysis.Multinomial Logistic regression was conducted across the three models to investi-gate the associations between WWI and acute,subacute and chronic pain.Model 1 did not involve any adjustments.Model 2 involved adjustments for age,gender,race,marital status,education level,and income.Model 3 was further adjusted for physical activity,alcohol consumption,smoking,and diabetes status.Results:This study involved 12 694 participants with an average age of(50.6±18.7)years.Among all the participants,9 614 people(75.74％)had no pain,870 people(6.85％)experienced acute pain,354 people(2.79％)suffered from subacute pain,and 1 856 people(14.62％)experienced chronic pain.The WWI of all the participants was(10.95±0.85)cm/√kg,divided into four groups based on quartiles:Group Q1(7.90-10.36)cm/√kg,group Q2(10.37-10.94)cm/√kg,group Q3(10.95-11.53)cm/√kg and group Q4(11.54-15.20)cm/√kg.With the increase of WWI,the analysis revealed a significant statistical difference in the participants'acute and chronic pain status(all P＜0.001).In Model 1,the prevalence of acute pain was lower in group Q2 and group Q4 compared with group Q1(group Q2:OR=0.765,95％CI:0.615-0.953,P=0.017;group Q4:OR=0.648,95％CI:0.503-0.835,P＜0.001).Compared with group Q1,the prevalence of chronic pain increased in group Q2,group Q3,and group Q4(group Q2:OR=1.365,95％CI:1.149-1.622,P＜0.001;group Q3:OR=1.291,95％CI:1.082-1.541,P=0.005;group Q4:OR=1.874,95％CI:1.579-2.224,P＜0.001).In Model 2,compared with group Q1,an increase in chronic pain preva-lence was still associated with an increase in WWI in other three groups(group Q2:OR=1.359,95％CI:1.137-1.624,P=0.001;group Q3:OR=1.260,95％CI:1.039-1.528,P=0.019;group Q4:OR=1.735,95％CI:1.413-2.132,P＜0.001).In Model 3,group Q4 had a 49.2％increased prevalence of chronic pain compared to group Q1(OR=1.492,95％CI:1.208-1.842,P＜0.001).However,in Models 2 and 3,no significant relationship was observed between acute pain and WWI(all P＞0.05).And none of the three models identified a significant association between subacute pain and WWI(all P＞0.05).Conclusion:For American adults,there was no significant correlation between WWI and acute pain or subacute pain.However,as WWI increases,so does the prevalence of chronic pain.Further validation of this conclusion through large-scale prospective studies is warranted.
