ABSTRACT
Objective:To investigate the correlation between serum lipoprotein (a) [LP(a)] and the severity of white matter hyperintensities (WMHs) in the middle-aged and elderly people in the community.Methods:Consecutive middle-aged and elderly residents residing in the community underwent physical examinations in the Affiliated Jiangning Hospital of Nanjing Medical University from June 2016 to August 2021 were retrospectively collected. Fasting venous blood was collected on the next day of admission to detect the level of Lp(a). During hospitalization, cranial MRI examination was performed and the severity of WMHs was graded using the Fazekas visual scoring method. Ordinal multivariate logistic regression analysis was used to determine independent related factors for the severity of WMHs.Results:A total of 1 752 patients were included in the analysis. There were 969 males (55.31%) and 783 females (44.69%). Their age was 66.18±10.32 years old. There were 1 167 patients (66.61%) in the mild WMHs group, 407 (23.23%) in the moderate WMHs group, and 178 (10.16%) in the severe WMHs group. Ordinal multivariable logistic regression analysis showed that after adjusting for confounding factors, a higher serum Lp(a) level was independently related to the severity of WMHs (with the first quartile as a reference, the third quartile: odds ratio 1.441, 95% confidence interval 1.050-1.976, P=0.023; the fourth quartile: odds ratio 1.717, 95% confidence interval 1.252-2.354, P=0.001). Conclusion:Serum Lp(a) is independently correlated with the severity of WMHs.
ABSTRACT
Objective:To investigate the correlation between global burden of small vessel disease(CSVD) on MRI and impaired spatial navigation in patients with CSVD.Methods:Patients with CSVD admitted to the Department of Neurology, Nanjing Jiangning Hospital from November 2020 to June 2022 were selected as the research subjects. The global burden of CSVD was scored according to the head MRI findings, and was divided into mild group (0-1 points), moderate group (2 points), and severe group (3-4 points). All patients were tested for spatial navigation function. Multivariate linear regression model was used to analyze the correlation between the global burden of CSVD and the spatial navigation function.Results:A total of 101 patients with CSVD were enrolled, including 37 patients in the mild group (36.6%), 28 in the moderate group (27.7%), and 36 in the severe group (35.6%). Age, glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol and creatinine, as well as the proportions of hypertension, diabetes, previous stroke or transient ischemic attack in the moderate group and the severe group were significantly higher than those in the mild group, while the high-density lipoprotein cholesterol was significantly lower than that in the mild group (all P<0.05). The spatial navigation function test showed that the environment + self-navigation, self-navigation and environment navigation functions of the moderate group and the severe group decreased significantly compared with the mild group (all P<0.05). Multivariate linear regression analysis showed that after adjusting for age, sex, hypertension, previous stroke or transient ischemic attack history and years of education, the global burden of CSVD and environment + self-navigation ( β=0.518, P<0.001), self-navigation ( β=0.481, P<0.001) and environmental navigation ( β=0.699, P<0.001) function had significant correlation. Conclusion:The global burden of CSVD is correlated with spatial navigation functions.
ABSTRACT
Objective To evaluate the application of Addenbrooke′s cognitive examination revised(ACE?R)scale to evaluate cognitive function in patients with chronic kidney disease(CKD). Methods We used ACE?R scale to evaluate the cognitive function on 205 cases of CKD patients received outpatient and inpatient treatment in renal Department of four hospitals in Nanjing. One?way ANOVA analysis ,receiver operating characteristic (ROC)curve and other statistical methods were adopted to compare differences. Results (1)There is significant difference of ACE?R scale scores among group NC?NCDs(89.18 ± 4.80),group Mild?NCDs(77.28 ± 5.80)and group Major?NCDs(55.90 ± 10.90)(F = 292.28,P < 0.01). There is significant difference between any two groups(all P<0.01).(2)(ACE?R)scale(AUC=0.944,P<0.01)showed significantly higher sensitivity than mini?mental state examination(MMSE)scale(AUC = 0.777,P < 0.01)on identifying Mild?NCDs patients with chronic kidney disease(P < 0.01);(3)The optimal cut?off value of total ACE?R score between group NC?NCDs and group Mild?NCDs was 83/84,(sensitivity 88.00%,specificity 85.90%,Youden index 0.739),the optimal cut?off value between group Mild?NCDs and group Major?NCDs was 83/84(sensitivity 89.70%,specificity 96.10%, Youden index 0.858). Conclusion ACE?R possesses a good ability in distinguishing different severity of cognitive impairment in patients with CKD. ACE?R can effectively identify early mild cognitive impairment ,which is suitable for clinical application as a tool to evaluating and studying of cognitive function in patients with CKD.
