Methods A total of 40 in-hospital elderly patients with stroke from June 2021 to June 2022 were enrolled in this study. They were divided into the experimental group and the control group randomly.The patients in the control group(n=20) received routine rehabilitation training,and the patients in the experimental group(n=20) received modified Wuqinxi training based on routine rehabilitation training. Before and after the intervention, forced expiratory volume in the first second(FEV1), forced vital capacity(FVC)and peak expiratory flow(PEF) were used to assess the pulmonary ventilation performance.The peak inspiratory flow(PIF) and maximum inspiratory pressure(MIP) were used to assess the inspiratory muscle function.Diaphragmatic excursion(DE) and diaphragmatic thickening fraction(DTF) detected by diaphragmatic ultrasound were used to evaluate the diaphragmatic function. Results No statistical difference was found between the two groups in the levels of FEV1, FVC, PEF, PIF, MIP, DE and DTF before the intervention(P>0.05). After the intervention, the levels of FEV1, FVC, PEF, PIF, MIP, DE and DTF in the experimental group were significantly higher than those before the intervention(P<0.05), which were also significantly higher than those in the control group except DTF(P<0.05). Conclusions The modified Wuqinxi training promotes the respiratory function in the elderly patients with stroke by improving the pulmonary ventilation function, inspiratory muscle function and diaphragm mobility.

Methods A total of 269 hospitalized patients with CKD from 2018 to 2021 were enrolled and divided into 4 groups according to CKD stages by chronic kidney disease epidemiology collaboration (CKD-EPI) formula: CKD 1 stage, CKD 2 stage, CKD 3 stage, CKD 4-5 stage. The levels of serum NT-proBNP and sST2, renal function indexes and cardiac function indexes in the patients with different CKD stages were compared, and the correlations between serum NT-proBNP and sST2 level with estimated glomerular filtration rate (eGFR) were analyzed.The ROC curve was used to assess the value of serum sST2 and NT-proBNP in the diagnosis of HF in the elderly patients with CKD. Results Among all participants, the levels of serum NT-proBNP(r=-0.546, P<0.001) and sST2 (r=-0.204, P=0.001) were negatively correlated with eGFR. The cut-off value of NT-proBNP for the diagnosis of HF in CKD patients rose with the increase of renal function stage, respectively: CKD 1 stage: 407 pg/mL, CKD 2 stage: 1211.5 pg/mL, CKD 3 stage: 3482 pg/mL, CKD 4-5 stage: 6512 pg/mL. In CKD 3 stage, the accuracy of the diagnosis of HF in CKD patients by NT-proBNP combined with sST2 was better than that by NT-proBNP alone. Conclusions The diagnostic cut-off value of NT-proBNP for HF in the patients with different stages of CKD increases with the deterioration of renal function, and the diagnostic threshold should be adjusted according to the eGFR. For the patients with moderate renal decline, the combination of NT-proBNP and sST2 can improve the diagnostic accuracy of HF. References | Related Articles | Metrics

Relationship between waist circumference and newly-developed hypertension in elderly people: a population-based cohort study LIU Heng-li, QU Qiang, SUN Jin-yu, SUN Wei, XIONG Ya-qing 2023, 37 (5):  464-469.  doi: 10.3969/j.issn.1003-9198.2023.05.008 Abstract ( 141 )   PDF (1167KB) ( 1081 )   Save Objective To explore the association between waist circumference and new-onset hypertension in the elderly people. Methods A total of 2038 elderly individuals(male/female: 1129/909, aged≥60 years) without hypertension at baseline were collected from the China Health and Retirement Longitudinal Study(CHARLS) 2011-2015. After preprocessing missing covariates via multiple imputation based on 5 replications, we compared baseline characteristics between individuals with new-onset hypertension and those without hypertension. The generalized additive model and SpearmaŃs correlation analysis were used to evaluate the association between waist circumference and baseline blood pressure. Multivariate Cox regression model was used to analyze the effect of waist circumference on new-onset hypertension. Moreover, restricted cubic spline was used to visualize the nonlinear correlation between waist circumference and new-onset hypertension. Results After a mean follow-up of 3.26 years, 717(35.2%) participants presented with hypertension. The generalized additive model and SpearmaŃs rank revealed the significant positive correlation of waist circumference with the baseline systolic and diastolic blood pressure(P<0.001). After adjusting age, sex, alcohol intake, smoking status, body mass index, low density lipoprotein and chronic diseases(diabetes mellitus, heart disease and stroke), the risk of new-onset hypertension increased by 19% with 10 cm increase in waist circumference. After multivariable adjustment, compared with the lowest quantile group, the hazard ratio(HR) of new-onset hypertension was 1.33(95%CI: 1.01-1.75) in the highest quantile group. Restricted cubic spline regression analysis showed that the risk of hypertension increased with the increase of waist circumference. Conclusions This study demonstrates that high waist circumference can be an independent risk factor for new-onset hypertension. References | Related Articles | Metrics

Effect of prognostic nutritional index on recurrent vertebral fractures after percutaneous vertebral augmentation in elderly female patients with osteoporotic vertebral compression fractures XU Feng-zhou, GAO Kai-qian, SUN Liang-liang, GAO Xue-feng, ZHANG Xiong, LIU Yong-qiang, ZHOU Jian-wei 2023, 37 (5):  470-474.  doi: 10.3969/j.issn.1003-9198.2023.05.009 Abstract ( 126 )   PDF (1123KB) ( 892 )   Save Objective To investigate the prevalence of reoccurrence of vertebral fractures in the elderly female patients with osteoporotic vertebral compression fractures(OVCF) after percutaneous vertebral augmentation(PVA) and the related influencing factors. Methods A total of 205 elderly women with OVCF after PVA were enrolled, and the basic data including age, body mass index(BMI), admission blood count, blood biochemical index and bone mineral density(BMD) were collected. The investigation period was from 2 to 40 months after PVA. The patients were divided into re-fracture group and control group according to whether vertebral re-fracture occurred. The factors influencing the recurrence of vertebral fractures were analyzed by single factor analysis and multivariate Cox regression model, and the predictive value of the independent factors was calculated by Logistic regression, and the receiver operating chavactevistic (ROC) curve was drawn. Results The incidence rate of recurrent vertebral fractures in the elderly women with OVCF after PVA was 20.5%, and prognostic nutritional index(PNI), BMD, age, and the use of anti-osteoporosis drugs were the independent influencing factors of recurrent vertebral fractures after PVA. The risk of re-fracture after PVA was lower in patients with high PNI compared with those with low PNI. There was an interaction between PNI and the use of anti-osteoporosis drugs, and the high PNI group had better efficacy. Compared with the model without PNI, the area of the ROC curve of the model with PNI was increased by 0.065(0.003-0.127). Conclusions High PNI is a protective factor for recurrent vertebral fractures after PVA in the elderly female patients with OVCF, and has predictive value for vertebral re-fracture after PVA, which can reduce the incidence of re-fracture by improving the efficacy of anti-osteoporosis drugs.

Analysis of influencing factors of chemotherapy tolerance in elderly patients with colorectal cancer DENG Shi-chao, SHEN Hao, SUN Qiang, CHEN Jia-dong, MA Bao-jin 2023, 37 (5):  500-504.  doi: 10.3969/j.issn.1003-9198.2023.05.016 Abstract ( 118 )   PDF (1461KB) ( 681 )   Save Objective To explore the influencing factors of chemotherapy tolerance in the elderly patients with colorectal cancer, in order to provide basis for screening elderly patients suitable for chemotherapy. Methods A retrospective study was conducted among 154 elderly patients(aged ≥65 years) who were diagnosed as colorectal cancer and received chemotherapy from 2017 to 2021, and the patients were divided into good chemotherapy tolerance group, basic chemotherapy tolerance group, and chemotherapy intolerance group according to the chemotherapy outcomes. The basic conditions, tumor conditions, nutritional status, emotional conditions and treatment conditions were compared in the three groups. Multivariate regression analysis was further performed to analyze the independent risk factors of chemotherapy tolerance in the elderly patients with colorectal cancer. Results Among 154 patients, 108 presented with good chemotherapy tolerance, 27 with basic chemotherapy tolerance (70.2%) and 19 with chemotherapy intolerance. Single factor analysis showed that age, number of basic diseases, tumor site, clinical stage, treatment mode, Performance Status(PS)Score, nutritional status, depression, and the levels of platelet, hemoglobin(Hb), prealbumin, albumin and carcinoembryonic antigen(CEA) were significantly different among the groups. Logistic regression analysis showed that tumor site, clinical stage, treatment mode, PS score, nutritional status, depression, Hb, albumin, and CEA were the independent influcencing factors for poor chemotherapy tolerance. Conclusions Elderly patients with colorectal cancer should receive active anti-cancer treatment. Chemotherapy as the main anti-cancer treatment should not be judged simply by age. Hb, albumin and CEA can be used as predictive indicators for prognosis. At the same time, tumor site, clinical stage, treatment mode, PS score, nutritional status and depression should also be considered as the independent influencing factors.
