Objective : To analyze the influencing factors associated with the coexistence of multidrug-resistantEscherichia coli(MDR-ECO) infection and active tuberculosis(ATB) in patients with lung infections. Methods: A total of 204 hospitalized patients with lung infections caused by MDR-ECO were enrolled. Among them, patients with coexisting ATB were identified and assigned to the observation group. Univariate and multivariate Logistic regression analysis were performed to identify the risk factors for the coexistence of MDR-ECO lung infection and ATB. Results : Factors such as patient age, neutrophil count, hemoglobin level, malignancy, rheumatoid arthritis, history of antibiotic exposure, and history of surgery within the past year were found to be influencing factors for the coexistence of MDR-ECO lung infection and ATB(allP<0.05). Specifically, advanced age(95%CI: 0.949-0.992,P=0.008), decreased neutrophils(95%CI: 0.750-0.922,P<0.001), and a history of antibiotic exposure(95%CI: 1.202-2.596,P=0.004) were identified as risk factors. Conclusion Some patients with MDR-ECO lung infections are prone to coexisting with ATB. Therefore, it is recommended to strengthen ATB screening among high-risk patients, including those at peak ages for susceptibility, with low neutrophil counts, and with a history of antibiotic exposure.

OBJECTIVE To explore the effect of the comprehensive unit-based safety program(CUSP)collaborative action strategy on reducing the incidence of catheter-associated urinary tract infection(CAUTI)in elderly patients.METHODS From Jun.to Nov.2024,the Seventh Medical Center of the PLA General Hospital implemented the CUSP collaborative action strategy for intervention.Comparisons were made between pre-intervention(from Dec.2023 to May 2024)and post-intervention(from Jun.to Nov.2024)regarding nurses' know ledge-attitude-practice(KAP)scores on CAUTI prevention,implementation rates of key nursing measures for elderly CAUTI prevention and CAUTI incidence rates among elderly patients.RESULTS The pre-intervention KAP score of nurses from geriatric de-partment on CAUTI prevention was(83.44±6.67),significantly lower than the post-intervention score(108.19±16.27)(P＜0.001).The implementation rates of 10 key nursing measures for elderly CAUTI prevention improved(P＜0.05).The incidence rate of CAUTI was 2.88‰(16/5 546)among 5 546 catheter days before the intervention,and the incidence rate of CAUTI was 0.73‰(4/5 496)among 5 496 catheter days after the intervention(P=0.008).CONCLUSIONS The CUSP collaborative action strategy effectively enhances the KAP levels of nurses from geriatric department on CAUTI prevention,improves the implementation rates of key nursing measures,and reduces CAUTI incidence rates among elderly patients.

Objective: To analyze the correlation between preschool children s emotional competence and home rearing environment in Shangrao City, so as to provide support for improving children s emotional competence development as well as their home rearing environment. Methods: A total of 1 242 children aged 3-6 years old from 10 kindergartens in Shangrao City were retrospectively investigated by stratified cluster random sampling method in December 2022, and the Children s Emotional Adjustment Scale-Preschool Version (CEAS-P) and the Home Nurture Environment Scale for children aged 3-6 were surveyed on parents of preschool children. The t-test was used to test the difference, Spearman correlation analysis and multiple linear regression were used to analyze the influencing factors of preschool children s emotional competence. Results: There were significant differences in emotional competence scores of preschool children for demographic indicators including age, place of residence, health status and whether they were only children ( F/t =5.98, 6.56, 38.00, 2.23, P <0.01). The emotional competence of preschool children was positively correlated with the home rearing environment ( r=0.62, P <0.01). Multiple linear regression analysis showed that diverse activities/play participation, social adaptation/self management, and emotional warmth/self expression in home rearing environment were positive predictors of children s emotional ability ( β =0.30, 0.28, 0.16), while neglect/intervention/punishment were negative predictors ( β =-0.09)( P <0.05). Conclusions The home rearing environment is a factor related to young children s emotional competence. It is suggested specific parenting initiatives such as enriching family activities and play, strengthening children s self adaptation and management, giving warmth and let children express emotions, and preventing child neglect, interference and punishment should be conducted to improve children s emotional competence.
