The predictive value of early cognitive assessment for cognitive function after 3-6 months in acute ischemic stroke patients / 中华行为医学与脑科学杂志

Objective To explore the predictive value of short term cognitive assessment in the acute phase of ischemic stroke for 3-6 months after stroke.Methods The demographic data,vascular risk factors,clinical and imaging data of 254 patients with acute ischemic stroke from August 2016 to December 2017 were prospectively registered.The cognitive function was assessed by Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) 3 weeks after stroke onset.Comprehensive cognitive function assessment was performed after 3-6 months of stroke.Multiple factor Logistic regression was used to screen the independent risk factors of cognitive domain and overall cognitive function in 3-6 months.Results Totally 254 consecutive patients with acute ischemic stroke were enrolled.Combined with the inclusion and exclusion criteria,161 patients completed the baseline cognitive assessment,and 138 completed the comprehensive cognitive assessment in 3-6 months after stroke.Logistic regression analysis showed that 3 weeks baseline cognitive status was an independent factor affecting memory (P＜0.05,OR =62.47,95％CI=13.00-205.00),execution (P＜0.05,OR=38.29,95％CI=8.00-170.00),language (P＜0.05,OR=6.46,95％CI=2.31-18.04) and information processing speed (P＜0.05,OR=5.88,95％CI=2.24-15.41) in 3-6 months after stroke.According to the number of impaired cognitive domains,the overall cognitive function was defined.There were 61 cases of no or mild cognitive dysfunction group and 77 cases of moderate or severe cognitive impairment group.Multifactor logistic analysis showed that baseline cognitive status was independent of the overall cognitive function of 3-6 months after apoplexy adjusting for the age and education level (P＜0.05,OR=25.32,95％ CI =7.52-85.39).Conclusion Short cognitive assessment in early apoplexy can predict the short-term functional status of cognitive domains such as memory,execution,language and information processing speed after stroke,and can also predict the overall cognitive level.

Application of MoCA and MMSE in screening for cognitive impairment in acute ischemic stroke / 中华行为医学与脑科学杂志

Objective To compare the applicability of the Beijing Version of the Montreal Cognitive Assessment (MoCA) and the Mini Mental State Examination (MMSE) in screening for cognitive impairment in patients with acute ischemic stroke for 2-3 weeks.Methods MoCA and MMSE were conducted in 201 patients with acute ischemic stroke within 2 to 3 weeks after the onset of stroke.With MoCA＜23 and MMSE ＜26 as the cut off value,we assessed the clinic effect of the MoCA and MMSE and explored the correlation between two instruments.Results The average scores of MoCA and MMSE scale were (20.5±4.3) and (25.4±3.5) points.The prevalence of cognitive impairment evaluated with MoCA and MMSE were 57.2％and 43.3％,respectively.MoCA showed significant correlation with MMSE score (Pearson's correlation coefficient=0.833,P＜0.001),and an agreement with Kappa values of 0.532 (P＜0.01) in screening for cognitive impairment.Conclusions The prevalence of cognitive impairment assessed with MoCA is higher than that of with MMSE when using MoCA＜23 and MMSE＜26 as the cut off values.Both instruments show a good agreement for screening cognitive impairment in acute ischemic stroke within 2 to 3 weeks following the disease onset.

The clinical significance of body composition monitor in assessing the dry weight of hemodialysis patients / 中国医师进修杂志

Objective To investigate the clinical significance of body composition monitor (BCM) in evaluating the dry weight of hemodialysis patients.Methods Fifty-four hemodialysis patients who reached the dry weight according to clinical assessment were enrolled.The volume load was measured with BCM,and the pre-dialysis blood pressure,plasma B type natriuretic peptide (BNP) and echocardiogram parameters were recorded.Results BCM results showed that,in 54 hemodialysis patients,15 patients presented overhydration and 13 patients underhydration.According to the results of BCM,all of the 15 overhydration patients and some of the 13 underhydration patients adjusted their dry weight.According to the BCM results and the pre-dialysis blood pressure,the patients were divided into 4 groups:group A (without overhydration,the pre-dialysis blood pressure ＜ 150 mmHg,1 mmHg =0.133 kPa),23 cases;group B (without overhydration,pre-dialysis blood pressure ≥ 150 mmHg),16 cases;group C (overhydration,pre-dialysis blood pressure ＜ 150 mmHg),7 cases;and group D (overhydration,pre-dialysis blood pressure ≥ 150 mmHg),8 cases.There were no significant differences in pre-dialysis,plasma BNP and the echocardiographic parameters among the 4 groups (P ＞ 0.05).Conclusions BCM is a simple and convenient tool to evaluate the volume status of hemodialysis patients,It can give guidance of dry weight regulation.Compared with the other clinical assessment methods such as pedal edema,the blood pressure and plasma BNP,it is more accurate and practical.

Study of the relation between serum adiponectin and coronary artery calcification score in patients with chronic kidney disease / 中国医师进修杂志

Objective To investigate the relation between serum adiponectin and coronary artery calcification score (CACS), and find the risk factors for CACS in patients with chronic kidney disease (CKD). Methods Twenty-nine patients with 3-5 stage CKD were selected. The serum adiponectin was measured by enzyme linked immunosorbent assay. The heart was scanned by 64-row spiral CT, and the CACS was calculated. The blood calcium, phosphorus, intact parathyroid hormone, total cholesterol, low density lipoprotein cholesterol, albumin, urea nitrogen, creatinine, uric acid and high sensitive C reactive protein levels were measured, and the calcium-phosphorus product and estimation glomerular filtration rate were calculated. Results In 29 patients with CKD, 24 cases (83%) had coronary artery calcification with different degree (CACS>0 score), and the average CACS was 508 (0-3 363) scores. There were statistical differences in systolic blood pressure, urea nitrogen and estimation glomerular filtration rate between CKD patients with CACS≥100 scores (15 cases) and CKD patients with CACS<100 scores (14 cases):(146.00± 13.00) mmHg (1 mmHg=0.133 kPa) vs. (123.00±9.00) mmHg, (15.44±8.36) mmol/L vs. (9.71±2.52) mmol/L and (21.77 ±11.81) ml/ (min·1.73 m2) vs. (38.71 ±11.56) ml/ (min·1.73 m2), P<0.01 or <0.05. Pearson correlation analysis results showed that CACS had positive correlation with systolic blood pressure, creatinine and uric acid, and negative correlation with albumin and estimation glomerular filtration rate. Mult-stepwise regression analysis results showed that systolic blood pressure and estimation glomerular filtration rate were the independent risk factors of CACS. Conclusions The patients with 3-5 stage CKD have severe coronary artery calcification. The systolic blood pressure and estimation glomerular filtration rate are the independent risk factors of coronary artery calcification.

The level of serum Klotho in patients with chronic kidney disease and its relationship with renal function / 中国医师进修杂志

Objective To detect the level of serum Klotho in chronic kidney disease (CKD) 3-5 stage patients and explore its relationship with the progress of renal function.Methods Twenty-nine patients with CKD 3-5 stage (CKD group) and 10 cases of age-matched non-CKD patients (control group) were enrolled in the study.The level of serum Klotho and fibroblast growth factor 23 (FGF23) were measured by enzyme-linked immunosorbent assay.Results The level of serum Klotho in CKD group was significantly lower than that in control group [(670.07 ± 146.22) ng/L vs.(1 125.50 ± 126.96) ng/L] (P ＜ 0.01).The level of serum FGF23 in CKD group was significantly higher than that in control group[(48.89 ± 44.28) ng/L vs.(10.48 ± 8.93) ng/L] (P ＜ 0.01).Pearson correlation analysis showed that the level of Klotho in CKD patients was positively correlated with estimated glomerular filtration rate (eGFR) and hemoglobin,and Klotho was negatively correlated with log urea nitrogen,log serum creatinine,log FGF23 and phosphate.Multiple regression analysis showed that log FGF23 and serum phosphorus were independent factors for serum Klotho level in patients with CKD.CKD patients were divided into rapid progression of renal function group (10 cases) and renal stability group (19 cases) according to annual rate of eGFR dechne.The patients in rapid progression of renal function group with lower serum Klotho [(580.27 ± 162.15) ng/L vs.(717.33 ± 115.22) ng/L],higher uric acid and more severe proteinuria [(448.00 ±65.21) mmol/L vs.(368.32 ±78.80) mmol/L,(1.99 ± 1.57) g/d vs.(0.60 ± 1.00) g/d] (P ＜0.05).Conclusions Serum Klotho level of CKD 3-5 stage patients decreases with the decline in renal function.Serum phosphate and FGF23 are the independent factors for serum Klotho.Serum Klotho may become the prediction index of renal function progress for patients with CKD.
