Abstract:Objective:To analyze the status quo and evolution trend of research on ventilator-associated pneumonia(VAP)in patients with mechanically ventilation(MV)using bibliometric methods.Methods:VAP literature was retrieved from the Web of Science Core Collection and Scopus database from its inception to March 2025.VOSviewer 1.6.19 and CiteSpace 6.3.R1 were used for national collaboration network,keyword co-occurrence/emergency detection,and time zone view analysis.Results:A total of 7,747 articles were included,with the United States having the most(2,119 articles),France having the highest centrality(0.17),and China ranking fourth in terms of number of articles(521 articles),but with a lower density of international collaborations(centrality 0.02).Keyword co-occurrence analysis showed that the research hotspots were"respiratory system"(centrality 0.35)and"infection control"(centrality 0.19).Keyword emergence detection revealed that the research frontier focused on"clinical outcomes,""acute respiratory distress syndrome(ARDS),""extracorporeal membrane oxygenation(ECMO),""mortality,"and"sequential organ failure score(SOFA)."The time zone view showed that VAP research has evolved through three stages:basic prevention and control(1986-2010),mechanism exploration(2009-2017),and precision intervention(2019-2025).Conclusion:VAP research in MV patients shows a paradigm shift from single-mode prevention to multidisciplinary integration.Future research should strengthen international collaboration to develop predictive models using multi-omics data,conduct cost-effectiveness assessments under different levels of medical resources,and construct a three-dimensional prevention and control system integrating the environment,host,and pathogen.

Abstract:Objective:To construct and validate the prediction model of subsyndromal delirium(SSD)in elderly emergency trauma patients after surgery.Methods:A retrospective analysis was conducted on the clinical data of 906 elderly trauma patients admitted to the hospital from June 2018 to October 2024.The patients were divided into a modeling group(n=635)and a validation group(n=271)at a ratio of 7∶3.In the modeling group,patients were further classified into SSD and non-SSD groups based on whether SSD occurred after surgery.The influencing factors were analyzed using the least absolute shrinkage and selection operator(LASSO)and multivariate Logistic regression.The Nomogram model for predicting the risk of SSD in elderly trauma patients in the emergency department was constructed using R 3.6.3 software and the rms package.The model's discrimination,calibration,and clinical applicability were evaluated using the area under the receiver operating characteristic(ROC)area under the curve(AUC),calibration curve,and decision curve analysis(DCA).Results:Among the 635 patients in the modeling group,204 patients developed SSD,with an incidence of 32.13%(204/635).The results of multivariate Logistic regression analysis showed that age,history of alcohol consumption,Injury Severity Score(ISS),Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score,mechanical ventilation,blood transfusion,length of stay in the intensive care unit(ICU),postoperative Numerical Rating Scale(NRS)score for pain,and limb restraint were all influencing factors for the occurrence of SSD in elderly trauma patients after emergency surgery(P<0.05).The AUC of the Nomogram model established based on the results was 0.877[95%CI(0.844,0.909)]in the modeling group and 0.836[95%CI(0.801,0.871)]in the validation group.The ROC curve,calibration curve,and DCA results indicated that the Nomogram model had high discrimination and consistency,and good clinical applicability.Conclusions:The risk prediction model for postoperative SSD in elderly emergency trauma patients constructed based on the influencing factors screened by LASSO regression has good discrimination and clinical applicability.

Abstract:Objective:To analyze the influencing factors of postoperative frailty in elderly patients with lower extremity arteriosclerosis obliterans,and to establish the relevant decision tree model.Methods:The clinical data of 260 elderly LEASO patients admitted to the hospital from January 2022 to December 2024 were retrospectively selected.The patients were divided into the frailty group(n=67)and the control group(n=193)according to whether frailty occurred after the operation.Logistic regression was used to analyze the influencing factors of postoperative frailty in elderly LEASO patients,and a related decision tree prediction model was constructed.Results:Among the 260 elderly patients with LEASO,67 cases developed frailty after surgery,with an incidence rate of 25.77%.Logistic regression analysis results indicated that age≥70 years[OR=4.184,95%CI(2.003,8.740)],solitude[OR=3.155,95%CI(1.609,6.190)],operation duration>90 min[OR=2.212,95%CI(1.148,4.261)],preoperative hemoglobin<110 g/L[OR=2.257,95%CI(1.126,4.525)],and preoperative albumin<35 g/L[OR=4.382,95%CI(2.164,8.875)]were risk factors for postoperative frailty in elderly patients with LEASO(P<0.05).The decision tree model constructed based on these risk factors had three layers,13 nodes,and 7 terminal nodes.The model selected preoperative albumin,age,living situation,preoperative hemoglobin,and operation duration as nodes,among which preoperative albumin level was the most important factor for postoperative frailty in elderly patients with LEASO.The model validation results showed that the area under the curve(AUC)was 0.803[95%CI(0.740,0.861)].Conclusions:Age≥70 years old,preoperative hemoglobin<110 g/L,solitude,operation duration>90 min,and preoperative albumin<35 g/L are risk factors for postoperative frailty in elderly LEASO patients.The decision tree model constructed based on these factors has good predictive efficacy.

Abstract:Objective:To explore the risk factors of catheter-associated urinary tract infection(CAUTI)in stroke patients,construct a risk prediction model,and evaluate its application effect.Methods:A total of 350 stroke patients admitted to the hospital from November 2021 to November 2023 were selected as the modeling group.The clinical data of all patients were retrospectively analyzed.Among them,70 patients with CAUTI were included in the infection group,and 280 patients without CAUTI were included in the non-infection group.Univariate and Logistic regression analyses were used to identify the risk factors for CAUTI in stroke patients,and a risk prediction model was constructed.The predictive efficacy of the model was evaluated using the receiver operating characteristic(ROC)curve.Another 95 stroke patients admitted to the hospital from December 2023 to December 2024 were selected as the validation group to evaluate the application effect.Result:Among 350 stroke patients,70 cases developed CAUTI,accounting for 20.00%(70/350).The results of the univariate analysis showed that there were statistically significant differences in gender,age,length of hospital stay,duration of urinary catheter placement,number of catheter insertions,D-dimer level,history of diabetes,and status of consciousness between the infection group and the non-infection group(P<0.05).The results of the Logistic regression analysis indicated that being female,age>75 years old,length of hospital stay≥10 days,duration of urinary catheter placement>7 days,number of catheter insertions>3 times,D-dimer>0.5 mg/L,having a history of diabetes,and having a state of consciousness disorder were risk factors for CAUTI in stroke patients(P<0.05).A risk prediction model was constructed,with the area under the ROC curve(AUC)being 0.858[95%CI(0.875,0.962)],the maximum Youden index being 0.705,the sensitivity being 0.842,and the specificity being 0.865.Conclusions:Being female,advanced age,long hospital stay,long duration of urinary catheter placement,multiple catheter insertions,elevated D-dimer level,history of diabetes,and state of consciousness disorder are all risk factors for CAUTI in stroke patients.Clinically,it is necessary to reasonably assess the high-risk factors of CAUTI,achieve early identification and prevention,and actively take effective nursing measures to reduce the incidence of CAUTI in stroke patients after urinary catheter placement.
