ABSTRACT

Objective:To investigate the effect of obesity on vascular anatomy and post-operative outcomes in patients undergoing carotid artery stenting (CAS), and to inform the choice of treatment options for obese patients.Methods:Patients who underwent CAS in the Stroke Center of First Hospital of Shanxi Medical University between January 1st, 2020 and December 31st, 2022 were collected, and their medical records and digital subtraction angiography images were collected. All patients were divided into obese group and non-obese group based on the body mass index at admission. Vascular anatomy and the incidence of peri-operative adverse outcomes were compared between the two groups. The three-step regression method was used to further explore the role of vascular anatomy in the correlation between obesity and peri-operative adverse outcomes in CAS.Results:A total of 298 patients were included. The Buffalo Risk Assessment Scale index was higher for the obese group, and high-risk vascular anatomy was more common in the obese group( P<0.05). The incidence of peri-operative stroke in the obese group was higher than that in the non-obese group (18.5% vs. 5.2%, P=0.007). The mediation analysis suggested the full mediation effect of high-risk vascular anatomy on obesity to influence the incidence of peri-operative stroke after CAS. Conclusion:Obesity increases the risk of post-operative adverse outcomes via inducing the development of complex vascular anatomy.

ABSTRACT

Stroke has become the leading cause of death and disability in Chinese adults, of which about 70% are ischemic stroke. Previous studies have shown that early enteral nutrition can improve the clinical outcomes of patients with acute stroke. This article reviews the impact of the timing and pathway of enteral nutrition on the clinical outcomes of the patients with acute stroke, in order to provide basis for clinical practice.

ABSTRACT

Objective:To investigate the correlation between low-density lipoprotein cholesterol (LDL-C) and hemorrhagic transformation (HT) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis using standard dose alteplase in the First Hospital of Shanxi Medical University from January 2014 to December 2019 were enrolled retrospectively. Head CT scan was performed within 24 h after thrombolytic therapy to identify the occurrence of HT. The demographic and baseline clinical data were compared between the HT group and the non-HT group. Multivariate logistic regression analysis was used to determine the correlation between LDL-C and HT after thrombolysis. Results:A total of 323 patients with AIS who received intravenous thrombolytic therapy were enrolled, their age was 65±12 years (range, 54-78 years), and 219 were males (67.8%). The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 4 (interquartile range, 3-9). Ninety one patients (28.17%) developed HT, of which 8 (2.48%) had symptomatic intracerebral hemorrhage. Univariate analysis showed that there were significant differences in LDL-C, age, baseline NIHSS score, baseline systolic and diastolic blood pressure, baseline fibrin degradation products, and the proportion of patients with atrial fibrillation and stroke etiology between the HT group and the non-HT group (all P<0.05). Multivariate logistic regression analysis showed that lower LDL-C (odds ratio [ OR] 0.531, 95% confidence interval [ CI] 0.358-0.788; P=0.002), higher baseline NIHSS score ( OR 1.063, 95% CI 1.010-1.120; P=0.020) and higher baseline systolic blood pressure ( OR 1.015, 95 CI 1.004-1.026; P=0.008) were the independent risk factors for HT after intravenous thrombolysis in patients with AIS. Conclusions:Low LDL-C is an independent risk factor for HT in patients with AIS after intravenous thrombolysis. The patients with lower LDL-C should be cautious in lipid-lowering therapy and be alert to the occurrence of HT.

ABSTRACT

Objetive To investigate physicians'knowledge regarding intravenous fibrinolytic therapy for acute ischemic stroke and whether their hospitals could meet the requirements for the therapy. Methods Questionnaires were mailed to 500 physicians from 153 hospitals in Shanxi including 112 secondary and 41 tertiary hospitals. 370 physicians returned valid questionnaires. Results One hundred thirty-four hospitals (87.6%) could provide 24-hour computed to?mography service, including 95 (84.8%) secondary hospitals and 39 (95.1%) tertiary hospitals. Alteplase stock was avail?able in 59 hospitals (38.6%), containing 25 (22.3%) secondary and 34 (82.9%) tertiary hospitals. Accuracy rates of 13 questions regarding intravenous fibrinolytic therapy for acute ischemic stroke ranged from 30.8% to 82.9%. Accuracy rates of 6 questions were lower than 50.0%. Conclusions The present study has revealed that physicians in this study have poor knowledge regarding the therapy. The situation can not meet the demand of healthcare, which partially ac?counts for the low rate in fibrinolytic therapy in Shanxi. Relevant training and suitable assessment should be carried out compulsively to ensure that physicians grasp necessary knowledge and skills.

ABSTRACT

Objective To implement and evaluate evidence-based guidelines for enteral nutrition support in acute stroke patients with dysphagia.Methods This study is a prospective before and after comparison study.Collected 200 acute stroke patients with dysphagia and divided them into test group (trained medical staffs) and control group(untrained medical staffs) equally according to the time order.Two groups of 100 patients were surveyed using a checklist before and after implementation of 10 guidelines about nutrition support.Before the implementation of guidelines,the staffs were enforced training,and summarized regularly.Compliances with guidelines by doctors and nurses were compared,and outcomes of patients were assessed.Results Compared with the control group,the correct implementation of the project significantly improved in the experimental group on nutritional risk screening (92.0%,64.0%; x2 =22.840),nutritional supplements selection (80.0%,48.0%; x2 =22.220),nutrition infusion methods (90%,18% ; x2 =1.040) and nutrition infusion adjustment (abdominal distension/adjusted:21/10,6/4;x2 =9.634,constipation/adjusted:41/40,57/53 ; x2 =5.122,all P < 0.05).The mortality rate,poor prognosis and length of stay in department of neurology intensive care unit and in hospital were not significant different between the experimental group and the control group.The incidence of hospital-acquired pneumonia was significantly lower in the experimental group (44.3%) than that in the control group (67.5%,x2 =7.281,P =0.007),but other patient outcomes were unaffected significantly.Conclusion Implementation of evidence-based guidelines for enteral nutrition support in acute stroke patients with dysphagia is associated with improvements in clinical quality and selected patient outcomes.

ABSTRACT

Objective To evaluate feasibility and reliability of using Simplified Acute Physiology Score Ⅱ (SAPS Ⅱ)in predicting mortality in critically ill patients with neurological diseases.Methods All 653 patients hospitalized in neurological intensive care unit (N-ICU) from Jan 2005 to Dec 2007 were retrospectively studied.SAPSⅡ scores were scaled upon admission at 24,48 and 72 h,and possibility of hospital mortality (PHM) was calculated based on SAPS Ⅱ score.Neurological diseases diagnosis made initially at time of hospitalization was classified into five categories:intracranial hemorrhage,cerebral infarction,neurologic infection,neuromuscular diseases and other neurologic diseases.At each of four time points,the SAPSⅡscores were compared between the survival group and death group,and the relationship of SAPS Ⅱ score and prognosis were analyzed.The calibration of the SAPS Ⅱ were accessed with the Hosmer-Lemeshow goodness-of-fit chi-squared statistic and the discrimination with area under the receiver operating characteristic curve (AUROC).Multivariate logistic regression was used to analyze the relationship between disease category and prognosis.Results SAPS Ⅱ scores in the death group (46.53±12.22,47.28±13.84,48.58±14.18 and 49.06±14.61)at each time point were significantly higher than those in the survival group (34.70±11.78,30.28±12.24,29.79±12.36 and 29.69±12.96;t=11.12,14.02,14.43 and 13.49 at 0,24,48 and 72 h,respectively,P<0.01).Furthermore,univariate logistic regression analyses demonstrated that SAPS Ⅱ score was correlated with prognosis (OR=1.080,1.100,1.109,1.100 at 0,24,48 and 72 h,respectively,P<0.01).The scores at 48 and 72 h were more accurate in predicting mortality.SAPS Ⅱ had good calibration at each time points (x2=5.305,7.557,6.369 and 8.540,P>0.05),however,the consistency of expected mortality with observed mortality was satisfactory only at 48 and 72 h(82.6%,83.4%),so was the discrimination ( AUROC=0.825,0.847 respectively).There was no correlation between disease categories and outcome.Conclusion SAPS Ⅱ scoring,best evaluated at 48 and 72 h after hospitalization,can be used as a reliable predictor of probability of mortality in patients hospitalized in N-ICU and prediction can be applied in these patients with all different neurology diseases.

ABSTRACT

Objective To investigate whether iron mass induces HO-1 overexpression and explore the role of HO-1 in rat intracerebral hemorrhage(ICH). Methods In this study,144 hydrated chloride aldehyde-anesthetized Sprague- Dawley rats were used,autologous blood were injected into the right caudate nucleus to establish the ICH model.Saline injection and health were served as controls.Deferoxamine(DFO)with an intraperitoneal injection served as intervention group.Enhanced Perl's reaction was used for iron staining and brain iron deposits were determined.Brain HO-1 level were examined by immunohistochemical analysis and reverse transcription polymerase chain reaction(RT-PCR). Results There was a 21-fold increase in iron deposits around the hematoma 7 days after the infusion of 100 μl of autologous blood.Markedly increased levels of perihematomal HO-1 immunoreactivity and HO-1 mRNA in all ICH rats were detected at 3-14 days.The addition of DFO significantly reduced iron deposits in the ipsilateral basal ganglia at 7-14 days after ICH.DFO also inhibited HO-1 overexpression at day 7,14.Correlations test showed that there were positive correlations of iron sediments with HO-1mRNA(r=0.647)and HO-1 immunopositive cells(r=0.209). Conclusions ICH causes iron accumulation in the brain.Iron overloading may induce HO-1 upregulation after ICH.Ratherly,the HO-1 moderate increasing possibly fits with the events,whereas HO-1 overexpression may result in its dysfunction.It may be prudent to intervene ICH with HO-1 inhibitor.
