ABSTRACT
Objective:To explore the occurrence time and risk factors of deep vein thrombosis (DVT) in patients with acute cerebral infarction, so as to guide clinical prevention and treatment.Methods:1 129 patients with acute cerebral infarction treated in Beijing Tiantan Hospital from May 2014 to May 2016 were selected as the research objects. According to whether DVT occurred, the patients were divided into DVT group ( n=22) and non DVT group ( n=1 107); The information was analyzed retrospectively and the occurrence time of DVT was counted. The independent risk factors of acute cerebral infarction complicated with DVT were analyzed by univariate and multivariate logistic regression. Results:The time of DVT in patients with acute cerebral infarction was 10.5 (4-14) days. Univariate analysis showed that there were significant differences in age, gender, atrial fibrillation, smoking, drinking, chronic obstructive pulmonary disease, peripheral artery disease, renal failure, anticoagulants, BMI, white blood cell, blood glucose at admission and length of stay between the DVT group and the non DVT group ( P<0.05). Multiple factors further confirmed that renal failure [odds ratio ( OR)=57.421; 95% confidence interval ( CI), 5.792-569.314)] and length of hospital stay ( OR=1.148; 95% CI: 1.071-1.232) were independent risk factors for DVT. Conclusions:The median time of DVT in patients with acute cerebral infarction was 10.5 days. Renal failure and hospital stay were independent influencing factors of DVT in patients with acute cerebral infarction. This is helpful to determine the best prevention and treatment duration of DVT in patients with acute cerebral infarction, make rational use of medical resources and formulate personalized prevention and treatment strategies.
ABSTRACT
Objective To compare the outcomes of endovascular treatment between intracranial large artery atherosclerosis stroke (LAA) and cardioembolic stroke (CE) in Chinese patients with acute anterior circulation ischemic stroke.Methods Patients with acute anterior circulation ischemic stroke treated with the Solitaire stent retriever were enrolled.The patients were divided into either a LAA group or a CE group according to etiological subtype.The outcomes were compared between 2 groups.Multivariable logistic regression analysis was used to determine the independent risk factors for poor outcome (defined as the modified Rankin Scale score ＞2 at 90 d after onset).Results A total of 126 patients were enrolled in the study,including 62 (49.2％) in the LAA group and 64 (50.8％) in the CE group.The proportions of poor outcome at 90 d (59.0％ vs.41.0％;x2 =5.482,P =0.019) and symptomatic intracerebral hemorrhage at 72 h (12.5％ vs.1.6％;Fisher exact test P =0.033) in the CE group were significantly higher than those in the LAA group.Multivariate logistic regression analysis showed that high baseline National Institutes of Health Stroke Scale scores was independently associated with poor outcome (odds ratio [OR] 1.119,95％ confidence interval [CI] 1.026-1.221;P =0.011),good collateral circulation was was independently associated with good outcome (OR 0.227,95％ CI 0.097-0.788;P =0.016),and etiological subtype was not independently associated with outcome (OR 1.280,95％ CI O.454-3.633;P =0.630).Conclusion Etiological subtype is not associated with outcome in patients with acute anterior circulation ischemic stroke treated with the Sofitaire stent retriever.
ABSTRACT
Objective Carotid artery stenosis is closely related not only with the cognitive function impairment, but also can cause patients to physical fatigue and a series of consequences.The aim of this study was to investigate the correlation between carotid artery stenting for carotid artery stenosis in patients with cognitive function improvement effect and fatigue and cognitive function in this paper. Methods One hundred cases of clinical data of patients with carotid artery stenosis of carotid artery stentingwere analyze pro-spectively.The cognitive scales of mini mental state examination (mini mental scale state examination, MMSE), Montreal cognitive as-sessment(Montreal cognitive, assessment, MoCA), activities of daily living scale (activities of dailyliving, ADL), fast vocabulary test ( verbal fluency) , Webster's count test, digit span test( working memory) , Digit Symbol Substitution Test ( speed) and the the fatigue scales of fatigue assessment scale-14 ( Fatigue Scale-14, FS-14) , fatigue severity scale ( FatigueSeverity Scale, FSS-9) were observed before and 3, 6 months after surgery.The correlation between fatigue and cognitive impairment was also analyzed Results Operation was successful in all patients, and no serious complications occurred after surgery.Patients'clinical symptoms were significantly im-proved compared with those on admission.MMSE, MoCA, ADL, verbal fluency test, Wechsler arithmetic, digit span and digit symbol substitution test results showed that, the scores were significantly improved compared with those on admission( P<0.05) , and with the time prolonging, cognitive function improved more obviously( P<0.001) .Compared with before operation,FS-14 score [ ( 7.11±1.37) vs (4.38±0.97)] and FSS-9 scores were significantly decreased6 months after operation, [(52.45±6.77) vs (43.29±7.21)](P<0.05). The correlation coefficient of FS-14 and MMSE, FFS 9 and MMSE were -0.357, -0.311 6 months after surgery, and the correlation coefficientof FSS-14 and MoCA, FSS-9 and MoCA were -0.547,-0.351, which showed a significant negative correlation (P<0.05). Conclusion Carotid artery stenting therapy can improve cognitive function and fatigue in patients with carotid artery stenosis, and the effect was more significant with the time prolonging, and there was a certain correlation between fatigue and cognitive impairment.
ABSTRACT
Objective Inflammation response is involved in the whole pathological process of acute cerebral infarction ( ACI) , but few reports are seen on its clinical implication in ACI patients .The purpose of this study was to investigate the predictive value of the differential count of leukocytes for stroke severity and early clinical outcomes in the acute phase of cerebral infarction . Methods We collected the clinical and laboratory data of 635 patients diagnosed with ACI within 72 hours of symptom onset and eval-uated the association between the differential count of peripheral blood leukocytes and stroke severity at admission and within 3 days af-ter admission as well as the clinical outcomes at discharge .The neural function impairment scores of the patients were obtained with The NIH Stroke Score ( NIHSS) at admission and on the third day after admission , and the therapeutic results evaluated with the modi-fied Rankin Scale ( mRS) , mRS >2 as poor prognosis .Analyses were performed on the correlation of the differential count of leuko-cytes with NIHSS and mRS scores and its influence on the ACI patients . Results At discharge , the mRS related influencing factors included the total count of leukocytes (OR=1.147, 95% CI:1.038-1.268), count of neutrophil cells (OR=1.227, 95% CI:1.00-1.369 ), count of lymphocytes ( OR =0.508, 95% CI:0.342-0.753), and neutrophil to lymphocyte ratio (NLR) (OR=1.150, 95%CI:1.008-1.314).the NIHSSs were correlated with the counts of leucocytes (r=0.078, P=0.024), neutrophil cells (r=0.083, P=0.019), and lymphocytes (r=0.010, P=0.004) at admission, and with the counts of leucocytes ( r =0.238, P <0.001), neutrophil cells (r=0.335, P<0.001), lymphocytes (r=-0.269, P<0.001), and NLR (r=0.423, P<0.001) on the third day after admission. Conclusion In the acute phase of cer-ebral infarction , the differential count of leukocytes and NLR are valuable for predicting the severity of neurologic impairment and early poor functional outcome .
ABSTRACT
Objective To investigate the clinical effect of angioplasty for symptomatic intracranial atherosclerotic stenosis. Methods Eighty-two patients with symptomatic intracranial atherosclerotic stenosis whom underwent angioplasty after the failure of standard medical therapy were enrolled from Nan-jing Stroke Registry Program from September 2010 to June 2013.Nine of them underwent routine balloon angioplasty alone and 73 underwent intracranial stenting.The median time from onset to surgery was 24.5 days.The occurrence of endpoint events (any stroke ≤30 d after procedure,death and ischemic stroke >30 d in guilty vessels or original stenosis had restenosis and needed to be treated again)was assessed. The incidence of restenosis was followed up with imaging (CTA or DSA). Results (1)In the 82 patients, the success rate of operation was 92.7%(n=72 ),and 78 (95.1%)received follow-up,4 were lost to follow-up.The median follow-up time was 22.5 months (range 9 to 29 months ).Ten patients had an endpoint event,7 of them were ischemic stroke,1 was cerebral hemorrhage,and two were severe asymptomatic restenosis who underwent stenting again.The endpoint events of 3 patients occurred at day 30 after procedure (at ≤24 h after procedure).Kaplan-Meier curves showed that the incidences of cumulative endpoint events at 1,6,12,and 24 months were 3.7%,8.6%,11%,and 13%,respectively.(2)60 patients (73.2%)received imaging examination (11 CTA and 49 DSA ).Restenosis occurred in 17 patients (28.3%),among them the incidence of symptomatic restenosis was 5%(n =3 ),and asymptomatic restenosis was 23.3%(n=14). Conclusion After a comprehensive assessment and a rigorous screening, the safety is high and the mid- and long-term efficacy are satisfactory in patients with symptomatic intracranial arterial stenosis who are treated with angioplasty when their medical treatment is invalid.
ABSTRACT
Currently,statins are one of the most important medications for the prevention and treatment of cardio-cerebrovascular diseases.In recent years,a large number of clinical studies and metaanalyses have confirmed that statins can effectively reduce the risks of the occurrence and recurrence of ischemic stroke.This article reviews the applications of statins in the primary prevention,acute treatment,and the secondary prevention of ischemic stroke.
ABSTRACT
Objective To determine prevalence of dementia in diabetics and non-diabetics, and in different age and gender groups. Methods A case-control study was conducted among participants aged 50 and over in Jing' an temple community in Shanghai. Subjects in diabetics group were matched to non-diabetics groups for age and sex with 1:1 matching. Personal information and case history were collected through questionnaire. The subjects were screened for dementia using the Mini Mental State Examination (MMSE). Subjects that screened positively (indicated by an MMSE score below 19, 21 and 24 among those with illiteracy, elementary school and above junior middle school education, respectively) were subsequently examined by a series of neuropsychological tests. Based on all available information, a diagnosis of dementia was defined according to the Diagnostic and Statistical Manual of Mental Disorders ( DSM )-Ⅳ criteria Results Prevalence of dementia of 4. 75% (23/484, 95% CI: 3. 03%-7.04%) in diabetics was higher than that of 2. 24% (11/490,95% CI: 1.13% -3.98%) in non-diabetics (X~2 = 4.54, P=0.03).Prevalence of dementia among diabetics in age groups of 60-69, 70-79 and 80 and above was 1.94% (2/103), 4. 43 % (9/203) and 14.12% (12/85, trend X~2 =18.04, P <0.01), and in non-diabetics was 1.43% (2/140), 2. 86% (6/210) and 5.00% (3/60, trend X~2 = 4.58, P=0.03), respectively.Prevalence of dementia among female and male in diabetics was 6.55% (19/299) and 2.06% (4/194) (X~2 = 5.18, P = 0.02), respectively, and in non-diabetics was 3.01% (9/299) and 1.05% (2/191).Conclusions Prevalence of dementia is significantly higher in diabetics than in non-diabetics, higher in women than men, and increases as age rises.
