Objective:To develop and evaluate the reliability and validity of the Unmet Needs Scale for Middle-aged and Young Women with Gynecological Cancer after Hysterectomy.Methods:Based on the Existence-Relatedness-Growth (ERG) theory, the initial version of the scale was developed through literature review, Delphi expert consultation, and a pilot survey. A total of 684 middle-aged and young women with gynecological cancer who underwent hysterectomy were selected using convenience sampling from three Class ⅢGrade A hospitals in Hebei Province between April and October 2024 for item analysis and psychometric testing.Results:The item-level content validity index ( I- CVI) of the scale ranged from 0.833 to 1.000, and the scale-level content validity index ( S- CVI) was 0.911. Exploratory factor analysis extracted seven common factors, explaining a cumulative variance of 71.083%. Confirmatory factor analysis showed good model fit. The final scale consisted of 45 items across seven dimensions: life needs, emotional needs, disease information needs, economic and medical care needs, needs for love and respect, self-actualization needs, and inner peace needs. Conclusions:The Unmet Needs Scale for Middle-aged and Young Women with Gynecological Cancer after Hysterectomy constructed based on ERG theory demonstrated good reliability and validity, and can serve as a useful tool for clinical assessment of unmet needs in this patient population.

Numerous c-mesenchymal-epithelial transition (c-MET) inhibitors have been reported as potential anticancer agents. However, most fail to enter clinical trials owing to poor efficacy or drug resistance. To date, the scaffold-based chemical space of small-molecule c-MET inhibitors has not been analyzed. In this study, we constructed the largest c-MET dataset, which included 2,278 molecules with different structures, by inhibiting the half maximal inhibitory concentration (IC₅₀) of kinase activity. No significant differences in drug-like properties were observed between active molecules (1,228) and inactive molecules (1,050), including chemical space coverage, physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. The higher chemical diversity of the active molecules was downscaled using t-distributed stochastic neighbor embedding (t-SNE) high-dimensional data. Further clustering and chemical space networks (CSNs) analyses revealed commonly used scaffolds for c-MET inhibitors, such as M5, M7, and M8. Activity cliffs and structural alerts were used to reveal "dead ends" and "safe bets" for c-MET, as well as dominant structural fragments consisting of pyridazinones, triazoles, and pyrazines. Finally, the decision tree model precisely indicated the key structural features required to constitute active c-MET inhibitor molecules, including at least three aromatic heterocycles, five aromatic nitrogen atoms, and eight nitrogen-oxygen atoms. Overall, our analyses revealed potential structure-activity relationship (SAR) patterns for c-MET inhibitors, which can inform the screening of new compounds and guide future optimization efforts.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To construct a patient decision aid(PtDA)for exercise training in pa-tients with chronic obstructive pulmonary disease(COPD)and explore its impacts on decision-making quality of patients' exercise regimens.Methods The development of the PtDA for exercise training in COPD patients was accomplished through literature analysis,the Delphi method,and user surveys,followed by an intervention study.A total of 59 inpatients with COPD were included as study sub-jects.The control group received routine care along with general exercise training guidance,while the intervention group received routine care combined with shared decision-making for exercise training based on the PtDA.The decision conflict and decision preparedness levels of patients in both groups were compared before the intervention and on the day of discharge.The exercise self-efficacy of pa-tients was measured before intervention,on the day of discharge,and 1 month and 3 months after dis-charge.Results The intervention group had significantly lower scores for decision conflict and signif-icantly higher scores for decision preparedness and exercise self-efficacy compared with the control group(P＜0.05).Conclusion The PtDA for exercise training can improve decision conflict and de-cision preparedness in COPD patients,enhance their exercise self-efficacy levels,and provide references for healthcare professionals in improving exercise adherence.

Objective To explore the application effect of pulmonary rehabilitation exercise health education program based on contemplation-action-maintenance (CAM) theory in patients with chronic obstructive pulmonary disease (COPD). Methods A total of 90 COPD patients were selected as the study subjects and randomly divided into control group (n=45) and intervention group (n=45). A total of 5 patients were excluded, with 42 cases finally included in the intervention group and 43 cases in the control group. The control group received routine exercise health education, while the intervention group received pulmonary rehabilitation exercise health education based on the CAM theory. The Readiness for Hospital Discharge Scale (RHDS), Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3), Benefit Finding Scale (BFS), exercise adherence scale scores and exercise tolerance[6-minute walk test (6MWT)]were compared between the two groups. Results At discharge, the RHDS score of the intervention group was higher than that of the control group, with a statistically significant difference (P < 0.05). At discharge and at 1 month as well as 3 months after discharge, the BREQ-3 and BFS scores of the intervention group were higher than those of the control group, with statistically significant differences (P < 0.05). At 1 month and 3 months after discharge, the exercise adherence scale scores and 6MWT distances of the intervention group were higher or longer than those of the control group, with statistically significant differences (P < 0.05). Conclusion The pulmonary rehabilitation exercise health education program based on CAM theory can improve the discharge readiness and exercise motivation of COPD patients, enhance their awareness of disease benefit and exercise compliance, and improve the exercise endurance of patients.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To gain a deep understanding of the supportive care needs of families of children with retinoblastoma (RB) through qualitative research.Methods:From March to May 2022, a semi-structured interview was conducted using purposive sampling to select the family members of 15 RB children in the Department of Eye Tumor of Beijing Tongren Hospital affiliated to Capital Medical University. Colaizzi 7-step analysis method was used to refine, extract, and analyze interview data.Results:The supportive care needs of the families of RB children were summarized into three themes and six sub-themes, namely, psychological needs (emotional listening and psychological support), knowledge needs (disease knowledge needs, children's post discharge guidance, internet resource needs), and economic needs (social resource integration) .Conclusions:RB, as a malignant eye tumor, often brings a heavy burden to families. Family members of children generally experience negative emotions such as anxiety and depression, as well as a lack of knowledge. The economic burden on families is heavy, and there is a high demand for supportive care. The supportive care program for families of RB children is not yet perfect, and nurses should provide emotional support and professional assistance to the families, providing help and guidance in psychological counseling, knowledge needs, economic assistance, and other aspects.
