With the increasing aging of the population in China,the problem of cognitive decline with age is becoming more prominent,and how to move forward to maintain and improve cognitive function in older adults has become an important research topic.Active participation in social activities has a protective effect on cognitive function in older adults.This paper summarizes the concepts of social activities,relationships with cognitive function,and strategies for promoting interventions.The corresponding nursing inspirations were proposed,aiming to provide new perspectives for improving cognitive function in older adults.

OBJECTIVE To investigate the molecular epidemiological characteristics of clinical isolates of carbapen-em-resistant Klebsiella pneumoniae(CRKP)resistant to ceftazidime/avibactam(CZA).METHODS From Jan.2022 to Dec.2023,totally 63 strains of non-repetitive CZA-resistant CRKP that were isolated for the first time from hospitalized patients of the First Affiliated Hospital of Nanchang University were enrolled in the study,and 50 strains of CZA-sensitive CRKP were randomly chosen as the research subjects.The drug susceptibility rates of the strains were observed.The drug resistance genes,virulence genes and capsular serotypes of the strains were detected by means of polymerase chain reaction(PCR).The molecular epidemiological characteristics of the strains were observed by using molecular biological techniques such as pulse field gel electrophoresis(PFGE)and multilocus sequence typing(MLST).RESULTS Among the CZA-resistant CRKP strains,45(71.43％)were iso-lated from sputum.The result of drug susceptibility testing showed that the drug resistance rates of the CZA-re-sistant strains to amikacin,aztreonam and minocycline were lower than those of the CZA-sensitive strains(P＜0.05),and the drug resistance rates of the CZA-resistant strains to tigecycline was higher than that of the CAZ-sensitive strains(P＜0.05).The carrying rates of blaKPC,blaNDM,blaSHV-1,blaTEM-1,blaCTX-M,blaqnrS,blaacc(6')-Ib and blarmtB genes of the CZA-resistant strains were relatively high.Among the detected capsular serotypes,K64(n=18,28.57％)was dominant.ST11(n=25,39.68％)was predominant strain among the CZA-resistant CRKP strains.CONCLUSIONS ST11 is dominant among the CZA-resistant CRKP strains.The strains carry with multiple drug resistance genes and virulence genes.The drug resistance rate of the CZA-resistant strains to tigecycline is higher than that of the CZA-sensitive strains,and it is necessary to attach great importance during the clinical treatment.

Lung cancer patients frequently experience multiple co-occurring symptoms that manifest as symptom clusters during treatment,severely compromising patients'quality of life.Sentinel symptoms,coexisting with symptom clusters,serve as predictive indicators for the emergence of these clusters.This study focuses on sentinel symptoms within symptom clusters in lung cancer patients,reviewing the current research status,identification methods,related intervention measures,and exist-ing research shortcomings.It summarizes the problems in current studies,with the goal of providing clinical nursing staff to as-sess and manage symptom clusters,as well as to conduct related nursing research.

Objective:To explore the current status and factors influencing physical activity among pre-frail and frail older adults in the community.Methods:Convenience sampling was used to select 207 pre-frail and frail older adults from Donghuashi community and Fangzhuang community in Beijing from April to June 2024 as study subjects. Older adults were surveyed for their general information, lifestyle behaviors, nutritional status, and physical activity. Binary Logistic regression was used to explore the factors influencing the level of physical activity among pre-frail and frail older adults in the community.Results:A total of 207 questionnaires were distributed and 204 valid questionnaires were recovered, with a valid recovery rate of 98.55%. The Physical Activity Scale for the Elderly score of the 204 community-based pre-frail and frail older adults was 86.87 (52.14, 125.00), and the form of activity was predominantly walking (98.5%, 201/204) and light domestic physical activity (85.8%, 175/204). Binary Logistic regression showed that taking a nap ( OR=3.614), abnormal nighttime sleep duration ( OR=4.077), fear of falling before or during exercise ( OR=7.895), and risk of malnutrition ( OR=9.263) were risk factors for levels of physical activity in pre-frail and frail older adults in the community ( P<0.05), and good exercise cognition ( OR=0.055) was a protective factor for physical activity levels ( P<0.05) . Conclusions:Pre-frail and frail older adults in the community have low levels of physical activity, which is dominated by walking and household activities. Community healthcare workers should strengthen the management of physical activity for pre-frail and frail older adults, cultivate their good living habits, improve their sleep quality, ensure sufficient night sleep, help them overcome the fear of falling before or during exercise, set up the correct concept of exercise, form a good cognition of exercise, and guide their family members to pay attention to the nutritional status of older adults, beware of the risk of malnutrition, and improve the level of physical activity to delay or even reverse the frail state.

Objective:To investigate the current status of physical function decline among community-dwelling elderly in Beijing and analyze its influencing factors.Methods:A convenience sampling method was used to select elderly individuals from Fangzhuang Community in Fengtai District and Donghuashi Community in Dongcheng District, Beijing, between February and July 2023. Data were collected using a general information questionnaire, lifestyle behavior survey, Mini-Mental State Examination (MMSE), and the Short Physical Performance Battery (SPPB). Binary Logistic regression analysis was performed to identify factors influencing physical function decline.Results:A total of 2 434 questionnaires were distributed, with 2 060 valid responses, yielding an effective response rate of 84.6%. Among the 2 060 community-dwelling elderly, 1 273 exhibited physical function decline. Logistic regression analysis revealed that age, history of stroke, alcohol consumption, annual physical examinations, social participation frequency, and cognitive impairment were significant factors influencing physical function decline among community-dwelling elderly ( P<0.05) . Conclusions:Physical function decline is prevalent among community-dwelling elderly in Beijing. Regular physical examinations, active social participation, early rehabilitation of stroke, and early screening and intervention for cognitive impairment can help slow the progression of physical function decline.

Objective:To conduct a scoping review of financial toxicity assessment tools both domestically and internationally,and to summarize their scoring methods,evaluation content,development approaches,reliability/validity,and application status,aiming to provide references for selecting or developing such tools.Methods:Following scoping review methodology,databases including CNKI,VIP,Wanfang,PubMed,Web of Science,Embase,and CINAHL were searched for studies on financial toxicity assessment tools,with the search period spanning from database inception to Oct 8,2024.Results:A total of 34 eligible studies were included,covering 14 financial toxicity assessment tools.These tools primarily focused on economic status,psychosocial responses,or coping behaviors.Tools developed by domestic scholars exhibited strong specificity but lacked generalizability.Conclusions:Existing financial toxicity assessment tools are diverse,yet their reliability and validity in Chinese patient populations require further validation.Most scales lack comprehensive dimensions,and domestically developed tools are overly specific.A universal assessment tool suitable for China's cultural and policy environment needs to be developed.

Objective:Based on the health ecological model, this study aimed to identify the influencing factors of cognitive function in older patients with common cardiovascular diseases in China, providing insights for the prevention of cognitive impairment in this population.Methods:A multi-stage sampling method was used to recruit 9 833 older patients with common cardiovascular diseases from ten ClassⅢ Grade A hospitals located in North China, East China, Central-South China, Southwest China, and Northwest China between January and December 2023. General information and cognitive status were assessed using a self-designed Ceneral Information Questionnaire and the Mini-mental State Examination. Binary Logistic regression was applied to explore factors influencing cognitive function.Results:Among the 9 833 patients, 2 394 (24.3%, 2 394/9 833) were identified with cognitive impairment. Binary Logistic regression analysis showed that intrapersonal level (gender, age, physical function, history of stroke, and history of chronic obstructive pulmonary disease), behavioral level (social activity participation and regular exercise), interpersonal network level (marital status and self-reported social support), and living and working conditions level (educational level, per capita monthly household income, and type of residence area) were the influencing factors of cognitive function ( P<0.05) . Conclusions:Cognitive function in older adults with cardiovascular diseases is suboptimal and influenced by multi-level and multidimensional factors. Healthcare providers should focus on monitoring high-risk individuals and promoting social participation and regular physical activity among this population.
