Methods: From August 2022 to April 2023, an investigation was conducted among urban and rural elderly individuals aged over 75 years in Tangshan City using the Activities of Daily Living Scale, the Revised Community Elderly Fall Risk Assessment Tool, and the Loneliness Scale. Results: The study included 750 urban and 740 rural elderly individuals aged over 75 years. Matrix analysis revealed a significant proportion of fall safety care needs across various daily life and spiritual care requirements. Multiple factor analysis indicated that advanced age, lower education levels, a greater number of chronic diseases, and lower levels of family and social support were associated with higher care demands among the elderly in both urban and rural areas. These differences were statistically significant (P < 0.05). Conclusion: The elderly in urban and rural areas demonstrate a high demand for fall safety care. Particular attention should be given to individuals with lower education levels, those who are widowed, those with multiple chronic diseases, and those with low levels of family and social support to better meet the diverse care needs of this population.展开更多

文摘To address the excessive complexity of monthly scheduling and the impact of uncertain net load on the chargeable energy of storage,a reduced time-period monthly scheduling model for thermal generators and energy storage,incorporating daily minimum chargeable energy constraints,was developed.Firstly,considering the variations in the frequency of unit start-ups and shutdowns under different levels of net load fluctuation,a method was proposed to reduce decision time periods for unit start-up and shut-down operations.This approach,based on the characteristics of net load fluctuations,minimizes the decision variables of units,thereby simplifying the monthly schedulingmodel.Secondly,the relationship between energy storage charging and discharging power,net load,and the total maximum/minimum output of units was analyzed.Based on this,daily minimum chargeable energy constraints were established to ensure the energy storage system meets charging requirements under extreme net load scenarios.Finally,taking into account the operational costs of thermal generators and energy storage,load loss costs,and operational constraints,the reduced time-period monthly schedulingmodel was constructed.Case studies demonstrate that the proposedmethod effectively generates economical monthly operation plans for thermal generators and energy storage,significantly reduces model solution time,and satisfies the charging requirements of energy storage under extreme net load conditions.

文摘BACKGROUND Studies have shown that patients with type 1 diabetes mellitus on continuous subcutaneous insulin infusion(CSII)require a lower dose of insulin than those treated with multiple daily injections(MDIs).However,it is unclear whether this is also the case for patients with type 2 diabetes mellitus(T2DM).AIM To compare insulin dosage requirements between CSII and MDI in T2DM,iden-tifying influencing factors associated with both therapeutic modalities.METHODS A total of 954 patients with T2DM were divided into two groups:CSII and MDI groups.The total daily insulin dose(TDD),TDD per kilogram per day(TDD/kg),and ratio of total basal insulin dose to TDD(%TBa)required to achieve the target blood glucose levels were compared between the two groups.In addition,factors affecting insulin dosage were analyzed in both groups of patients.RESULTS Compared to the CSII group,the MDI group required a higher TDD[median(interquartile)]:30.00(24.00,38.00)U/day vs 26.40(21.60,32.40)U/day;P<0.01,TDD/kg and%TBa.In the MDI group and CSII groups,an increase in TDD was independently associated with an increase in body mass index(BMI),waist circumference(WC),fasting plasma glucose(FPG),and glycated hemoglobin(HbA1c).The pathophysiology of type 2 diabetes mellitus(T2DM)mainly involves insulin resistance and progressiveβ-cell failure,which leads to increased blood glucose levels(hyperglycemia)[1-3].Treatment for T2DM includes antidiabetic medications and insulin therapy[4,5].Patients with T2DM withβ-cell failure usually require insulin therapy[6-8].Continuous subcutaneous insulin infusion(CSII)and multiple daily injections(MDIs)are two major insulin therapies for controlling hyperglycemia in these patients.However,excessive insulin therapies may cause problems such as hypoglycemia,weight gain,and iatrogenic hyperinsulinemia[9].Therefore,attention should be paid to the dosage of insulin used.The establishment of insulin regimens for CSII and MDI therapies is primarily guided by physicians’empirical judgment.To date,there have been few clear guidelines or recommendations on the appropriate insulin dose during CSII and MDI treatment for T2DM[10].Yang et al[11]studied insulin doses and related factors in the CSII treatment of patients with T2DM[12].However,these studies did not cover the dose setting and related factors in MDI treatment.Previous studies have shown that patients with type 1 diabetes mellitus treated with CSII require less insulin than those treated with MDIs[13-15].However,it is unclear whether patients with T2DM on CSII also require less insulin than patients on MDI.Therefore,the present study determined the difference in insulin dosages between CSII and MDI therapies and evaluated the related factors in patients with T2DM.It also systematically analyzed the insulin dose characteristics of MDI and CSII in 954 hospitalized patients with T2DM,aiming to optimize the insulin dosage regimen and provide clinical references for guiding the application of CSII and MDI in patients with T2DM.

文摘Objective: To examine the daily life care, spiritual comfort, and fall safety care needs of the elderly in urban and rural areas of Tangshan, along with their influencing factors. Methods: From August 2022 to April 2023, an investigation was conducted among urban and rural elderly individuals aged over 75 years in Tangshan City using the Activities of Daily Living Scale, the Revised Community Elderly Fall Risk Assessment Tool, and the Loneliness Scale. Results: The study included 750 urban and 740 rural elderly individuals aged over 75 years. Matrix analysis revealed a significant proportion of fall safety care needs across various daily life and spiritual care requirements. Multiple factor analysis indicated that advanced age, lower education levels, a greater number of chronic diseases, and lower levels of family and social support were associated with higher care demands among the elderly in both urban and rural areas. These differences were statistically significant (P < 0.05). Conclusion: The elderly in urban and rural areas demonstrate a high demand for fall safety care. Particular attention should be given to individuals with lower education levels, those who are widowed, those with multiple chronic diseases, and those with low levels of family and social support to better meet the diverse care needs of this population.
文摘With China’s rapidly aging population and the growing preference for aging in place,digital monitoring technologies have emerged as potential tools to support older adults in managing their activities of daily living(ADLs).This study explores the perceptions and acceptance of these technologies among elderly individuals living alone and their informal caregivers(ICs)in Nanshan District,Shenzhen.Grounded in the Unified Theory of Acceptance and Use of Technology(UTAUT),the study employed semi-structured and photo-elicitation interviews to analyze how performance expectancy,effort expectancy,social influence,and facilitating conditions shape technology adoption.The findings reveal clear intergenerational differences:caregivers show higher acceptance and a better understanding of the benefits and functionalities of wearable and environmental monitoring devices,while older adults often express skepticism due to concerns over privacy,usability,and cost.Many elderly participants also cite discomfort,technical complexity,and lack of training as barriers to adoption.Despite these obstacles,both groups acknowledge the potential safety and health benefits of such technologies.The study highlights the need for privacy-by-design features,customized user interfaces,and enhanced digital literacy programs tailored to both elderly users and their caregivers.The research contributes to a sociotechnical understanding of aging-in-place technologies in China and provides actionable insights for developers,policymakers,and healthcare practitioners aiming to enhance home-based elder care.

文摘Objective:To systematically explore the effectiveness of combining Enhanced Recovery After Surgery(ERAS)nursing and empathy intervention for postoperative patients with glioma.Methods:A total of 54 patients with glioma undergoing surgical treatment were selected for the study.The patients were admitted to the hospital between April 2023 and April 2025.The patients were divided into an observation group(n=27)and a control group(n=27)based on a random number table method.Relevant intervention indicators were compared between the two groups.Results:Compared with the control group,the postoperative recovery indicators in the observation group showed significant differences(P<0.05).After intervention,the scores of stress psychological indicators,FMA,NHISS,and ADL in the observation group were all better than those in the control group(P<0.05).The incidence of complications in the observation group was significantly lower than that in the control group(P<0.05).Conclusion:The combined application of empathy intervention and ERAS nursing effectively regulates the postoperative stress psychological state of patients with glioma,significantly improves their limb and neurological functions as well as daily living abilities,accelerates postoperative recovery,and reduces complications.This approach is feasible for wider implementation.

文摘Background Rumen bacterial groups can affect growth performance,such as average daily gain(ADG),feed intake,and efficiency.The study aimed to investigate the inter-relationship of rumen bacterial composition,rumen fermentation indicators,serum indicators,and growth performance of Holstein heifer calves with different ADG.Twelve calves were chosen from a trail with 60 calves and divided into higher ADG(HADG,high pre-and post-weaning ADG,n=6)and lower ADG(LADG,low pre-and post-weaning ADG,n=6)groups to investigate differences in bacterial composition and functions and host phenotype.Results During the preweaning period,the relative abundances of propionate producers,including g_norank_f_Butyricicoccaceae,g_Pyramidobacter,and g_norank_f_norank_o_Clostridia_vadin BB60_group,were higher in HADG calves(LDA>2,P<0.05).Enrichment of these bacteria resulted in increased levels of propionate,a gluconeogenic precursor,in preweaning HADG calves(adjusted P<0.05),which consequently raised serum glucose concentrations(adjusted P<0.05).In contrast,the relative abundances of rumen bacteria in post-weaning HADG calves did not exert this effect.Moreover,no significant differences were observed in rumen fermentation parameters and serum indices between the two groups.Conclusions The findings of this study revealed that the preweaning period is the window of opportunity for rumen bacteria to regulate the ADG of calves.
