ABSTRACT
Objective:To retrieve, evaluate and summarize the best evidence of exercise reversal intervention in the elderly with cognitive frailty, and to provide evidence for guiding exercise in elderly patients.Methods:This study was a summary of evidence-based nursing evidence. Based on the PIPOST (P: Population; I: Intervention; P: Professional; O: Outcome; S: Setting; T: Type of evidence) mode, the evidence of exercise reversal intervention in the elderly with cognitive frailty in 25 relevant guideline network and association websites, Chinese and foreign language comprehensive databases such as PubMed, CINAHL, Web of Science, Embase, Chinese Biomedical Database, China National Knowledge Internet and others were searched, extracted and integrated. The retrieval time was from January 1, 2013 to February 14, 2022.Results:A total of 22 articles were included, including 3 guidelines, 2 expert consensuses, 1 clinical decision-making, 1 evidence summary, 9 Meta analysis, and 6 randomized controlled trials. Finally, 28 pieces of the best evidence including 7 dimensions were namely formulate principles,overall assessment, exercise mode, exercise intensity, exercise time and frequency, exercise management, health guidance.Conclusions:This study summarized the best evidence of exercise intervention in the elderly with cognitive frailty, which are systematic, comprehensive, rigorous, and reliable. It can provide references for healthcare administrators to dynamically evaluate patients′cognitive frailty status, formulate personalized exercise programs, and standardize exercise guidance for patients, so as to delay or even reverse cognitive frailty.
ABSTRACT
Objective:To investigate the incidence of social isolationin community elderly patients with knee osteoarthritis and analyze its influencing factors.Methods:From January to April 2021, 240 community elderly with knee osteoarthritis in three community health service centers in Taiyuan (Yingbin community, Dawang community and Pingyang second community) were selected as research objects by convenient sampling method. They were investigated by general data questionnaire, Lubben Social Network Scale-6(Lubben-6), Geriatric Depression Scale-15, Perceived Social Support Scale, Numerical Rating Scale. Single factor analysis and binary Logistic regression analysis were used to explore the influencing factors of social isolation in elderly patients with knee osteoarthritis.Results:The prevalence of social isolation among community elderly patients with knee osteoarthritis was 43.33% (104/240) . The results of binary logistic regression analysis showed that age ( OR = 2.228, 95% CI 1.436-3.457), complicated diseases ( OR = 1.733, 95% CI 1.028-2.919), exercise ( OR = 0.560, 95% CI 0.360-0.869), depression ( OR = 3.603, 95% CI 1.768-7.339), comprehension of social support ( OR = 0.424, 95% CI 0.253-0.710) and pain ( OR = 1.792, 95% CI 1.147-2.799) were the influencing factors of social isolation in elderly patients with knee osteoarthritis ( P<0.05). Conclusions:The degree of social isolation in community elderly patients with knee osteoarthritis is relatively high, and is affected by many factors. Community medical staff should formulate targeted nursing intervention plans based on their influencing factors to reduce the occurrence of social isolation.
ABSTRACT
Objective To establish the musculoskeletal multi-body dynamic foot-ground contact model and explore its applicability at different speed. Methods The gait data of the subjects at different speed were collected, and the foot-ground contact model was established based on the full body model from the musculoskeletal multibody dynamic software AnyBody. Then the calculated ground reaction forces (GRFs) and ground reaction moments (GRMs) at different speed (slow walking, normal walking, fast walking and jogging) were compared with the measurements from the force plates. Results The predicted GRFs and GRMs correlated well with the experimental measurements at slow, normal and fast speed (stride speed ranged from 0.69 to 1.68 m/s). The correlation coefficients between predicted and measured GRFs were greater than 0.875 and the correlation coefficients for GRMs were greater than 0.9. Conclusions The developed foot-ground contact model could simultaneously predict GRFs and GRMs with good accuracy, thus eliminating the dependency on force plates. The model could be applied to low-speed gait conditions, such as the elderly and pathological gait.
ABSTRACT
Objective To investigate the clinical significance of CD28 expression on peripheral blood T lymphocytes in children with juvenile idiopathic arthritis (JIA).Methods Flow cytometry and tri-color direct immunofluorescence were used to examine CD3 + T lymphocyte subsets and CD28 expression in whole blood (using the no-wash method) from 36 children with JIA.Results During the active phase of disease,the frequency of CD28 + expression on both CD4 + and CD8 + T cells in the peripheral blood of children with JIA was significantly lower than in normal controls (P ＜ 0.01).The frequency of CD4 + CD28-T cells in the peripheral blood of children with JIA was significantly higher than in normal controls (P ＜ 0.01).CD4 + T cell counts in the peripheral blood of children with JIA,which were mostly of the CD4 + CD28-T cell subtype,were significantly higher than in normal controls (P ＜ 0.01),whereas the CD8 + T cell count was significantly reduced (P ＜0.01).During the resting phase,CD4 +/CD8 + T cell counts and CD28 expression in the peripheral blood of children with JIA were significantly different from normal controls (P ＞ 0.05).Conclusions The frequency of CD4 + CD28-T cells can be used as an indicator of the active phase of JIA.CD4 + T cell and CD4+ CD28-T cell apoptosis was inhibited in JIA patients.These immune-active T lymphocytes with continued survival can promote the occurrence and development of JIA.
