ObjectiveTo systematically review the effectiveness and safety of argatroban for patients with acute ischemic stroke.
MethodsPubMed (1966 to 2013.12), EMbase (1966 to 2013.12), CENTRAL (2013.12), CBM (1978 to 2013.12), VIP (1989 to 2013.12), CNKI (1980 to 2013.12) and CDFD (for masters and Phds, 1999 to 2013.12) were electronically searched for randomized controlled trials (RCTs) on argatroban for patients with acute ischemic stroke. Meanwhile, relevant data were retrieved by hand search and the data from pharmaceutical factories (TIPR Pharmaceutical Responsible Co. Ltd) were collected. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.2 software.
ResultsA total of 11 RCTs involving 889 patients were finally included. The results of meta-analysis showed that the argatroban group was better than the control group in improving patients' neurologic impairment scores (SMD=0.71, 95%CI 0.56 to 0.88, P < 0.000 01), and the effectiveness of neurological function (total result:OR=2.65, 95%CI 1.84 to 3.80, P < 0.000 01; placebo-controlled trial:OR=2.18, 95%CI 1.27 to 3.72, P=0.004; non-placebo-controlled trial:OR=3.09, 95%CI 1.89 to 5.06, P < 0.000 01), all with significant differences. No significant difference was found between the argatroban group and the control group in the long/short-term motilities or dependence rates as well as in the incidence of adverse reaction (OR=1.55, 95%CI 0.60 to 4.01, P=0.37).
ConclusionCurrent evidence shows that argatroban could improve neurologic impairment of patients with acute ischemic stroke without severe bleeding events or other adverse reaction. However, further studies are needed to confirm its effects on reducing rates of death and disability in treating acute ischemic stroke.
Objective To investigate the medication adherence to antihypertensives, antidiabetics, and lipid-lowering agents and its influence on the prognosis of individuals at high risk of stroke. Methods A total of 16892 residents aged 40 years or above in eight communities in Sichuan participated in a face-to-face study from May to September 2015. A database of a high-risk population of stroke in Sichuan province was established, and data were collected via using a standardized structured questionnaire by experienced investigators, including the treatment status and medication compliance of participants with hypertension, diabetes, or dyslipidemia during the follow-up period. Multiple logistic regression analyses were performed to explore the influencing factors of medication adherence and its influence on the prognosis of individuals at high risk of stroke. Results A total of 2893 participants at high risk of stroke were enrolled. The treatment rates of hypertension, diabetes, and dyslipidemia were 50.1%, 49.2%, and 5.1%, respectively, when the high-risk individuals were identified. At the end of follow-up (with a median follow-up period of 4.8 years), the treatment rates of hypertension, diabetes, and dyslipidemia were 24.8%, 25.0%, and 7.9%, respectively. Medication adherence to antihypertensives, antidiabetics, and lipid-lowering agents were 27.8%, 25.5%, and 18.1%, respectively. Multiple logistic regression analyses showed that the education level of high school or above [odds ratio (OR)=2.134, 95% confidence interval (CI) (1.098, 4.147), P=0.025], medical insurance for urban residents [OR=1.556, 95%CI (1.086, 2.230), P=0.016] and urban employees [OR=2.325, 95%CI (1.362, 3.967), P=0.002], having fewer children [OR=0.819, 95%CI (0.719, 0.933), P=0.003], and family history of stroke [OR=1.559, 95%CI (1.066, 2.282), P=0.022] were associated with greater adherence to antihypertensives; medical insurance for urban employees was associated with greater adherence to antidiabetics [OR=2.494, 95%CI (1.173, 5.300), P=0.018]. After adjusting for confounding factors, failure to regular use of antihypertensives [OR=2.617, 95%CI (1.414, 4.842), P=0.002], antidiabetics [OR=3.909, 95%CI (2.394, 6.380), P<0.001], and lipid-lowering agents [OR=4.828, 95%CI (2.581, 9.033), P<0.001] in patients with hypertension, diabetes, and dyslipidemia, respectively were associated with increased risk of ischemic stroke during the follow-up period. Regular use of lipid-lowering agents in patients with dyslipidemia was associated with an increased risk of intracerebral hemorrhage during the follow-up [OR=4.371, 95%CI (1.156, 16.530), P=0.030]. Conclusions The prevalences of hypertension, diabetes, and dyslipidemia are high in high-risk individuals of stroke in Sichuan province. However, the treatment rates are unsatisfactory, and the medication adherence is poor. The medication adherence is affected by a variety of demographic and socioeconomic factors. Regular treatments of hypertension, diabetes, and dyslipidemia reduce the risk of ischemic stroke in individuals at high risk of stroke, but regular use of lipid-lowering agents in patients with dyslipidemia is associated with an increased risk of intracerebral hemorrhage during the follow-up.
ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) in the patients with acute ischemic stroke, in order to provide effective guidance for clinical prevention and treatment.MethodsFrom November 2016 to November 2019, 330 patients with acute ischemic stroke admitted to the Department of Neurology of West China Hospital of Sichuan University and the Department of Neurology of the Sixth People’s Hospital of Chengdu were selected as the research object. The clinical data of the patients were analyzed retrospectively. According to whether SAP occurred, they were divided into infected group and non-infected group. Multivariate logistic regression model was used to analyze the risk factors of SAP.ResultsA total of 71 cases of SAP occurred in patients with acute ischemic stroke, accounting for 21.52%. Logistic regression analysis showed that age≥70 years old [odds ratio (OR)=3.677, 95% confidence interval (CI) (1.452, 9.311), P=0.006], chronic lung disease [OR=4.985, 95%CI (1.558, 15.952), P=0.007], disturbance of consciousness [OR=7.147, 95%CI (1.617, 31.587), P=0.009], bulbar palsy [OR=5.909, 95%CI (2.668, 13.089), P<0.001], the use of nasal feeding tube [OR=7.427, 95%CI (1.681, 32.812), P=0.008] were independent risk factors for SAP in patients with acute ischemic stroke.ConclusionsAge≥70 years old, chronic lung disease, disturbance of consciousness, bulbar paralysis and use of nasal feeding tube are independent risk factors for SAP. It is necessary to strengthen the management of these risk factors in order to identify high-risk patients with SAP early, and develop intervention strategies for risk factors, so as to improve the prognosis.
Objective To assess the clinical efficacy and safety of proton pump inhibitor （PPI） and H2RA for stress ulcer bleeding in stroke patients. Methods Randomized controlled trials （RCT） were identified from MEDLINE （ 1966- Oct. 2005 ） ,EMBASE （ 1984- Oct. 2005 ）, The Cochrane Library （ Issue 4,2005 ）, CBMdisc （ 1980- Oct. 2005 ） and VIP（ 1980- Oct. 2005 ）. We handsearched the related published and unpublished data and their references. The quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 4. 2.7 software was used for data analysis. Results Twenty RCT were included with 2 624 patients. The results of meta-analysis were listed as follows： （1） stress ulcer bleeding （SUB） ： PPI （ OR 0.14,95% CI 0.08 to 0.24, NNT = 3 ） and H2RA （OR 0.24,95% CI 0.15 to 0.39, NNT =5） significantly reduced the incidence of SUB in comparison with control group. PPI significantly reduced the incidence of SUB compared with H2R.A（P 〈0. 00001 ）. （2） Mortality： PPI （OR 0.22,95% CI 0. 11 to 0.47, NNT =8） and H2RA （OR 0.53,95% CI 0. 34 to 0.81, NNT =16） significantly decreased the mortality compared with non-prophylaxis group. PPI significantly decreased the mortality compared with H2RA （OR 0.28,95% CI 0.09 to 0. 89）. （3） Adverse effect： There were not evident adverse effects in both PPI and H2RA groups. Conclusions PPI and H2RA may reduce the incidence and mortality of SUB in stroke patients, and PPls are better in reducing incidence of SUB than H2RA.
Objective To study the application effect of Snyder hope theory combined with Satir model in the rehabilitation therapy of young and middle-aged patients with stroke. Methods A total of 224 young and middle-aged patients with stroke admitted to Zhongshan Hospital of Fudan University between August 2018 and August 2020 were divided into four groups (control group, Satir group, Snyder group, and combined group) according to the random number table method by taking admission time as sequence. All patients were given rehabilitation training on the basis of conventional treatment, and the Satir group was given group guidance of Satir model, the Snyder group was given hope therapy based on Snyder hope theory, and the combined group was given intervention combined Snyder hope theory with Satir model. All patients were continuously treated for six weeks. The scores of Herth Hope Index (HHI), Self-perceived Burden Scale (SPBS), exercise rehabilitation willingness questionnaire, Health Promoting Lifestyle Profile Ⅱ (HPLP Ⅱ), and Simplified Coping Style Questionnaire (SCSQ) were compared among the four groups before and after intervention. Results There were 53, 52, 54, and 52 patients enrolled in the control group, the Satir group, the Snyder group, and the combined group, respectively. The differences among the four groups in basic information such as sex, age, and type of stroke and the scores of the above scales before intervention were not statistically significant (P>0.05). After intervention, the total scores of HHI scale (27.65±6.34, 30.54±6.85, 32.79±7.12, 35.08±7.63), scores of exercise rehabilitation willingness (39.85±8.16, 40.52±7.93, 40.17±8.25, 43.81±7.46), total scores of HPLP Ⅱ scale (149.87±26.08, 159.32±26.73, 165.89±28.01, 173.18±28.54), and scores of positive coping style of SCSQ scale (19.65±5.08, 22.46±5.29, 25.04±4.91, 28.45±5.12) of the four groups significantly increased compared with those before intervention (P<0.05), while the total scores of SPBS scale (27.35±4.92, 23.74±5.02, 25.16±4.98, 21.49±5.27) and scores of negative coping style of SCSQ scale (4.83±1.25, 3.71±1.02, 3.94±1.08, 4.13±0.96) significantly decreased compared with those before intervention (P<0.05); the scores of HHI scale, exercise rehabilitation willingness, HPLP Ⅱ scale, and positive coping style of SCSQ scale of the combined group were higher than those of the other three groups (P<0.05), while the score of SPBS scale was lower than that of the other three groups (P<0.05). Conclusions Snyder hope theory combined with Satir model for rehabilitation therapy of young and middle-aged patients with stroke can help to improve the hope level, reduce the self-perceived burden, and improve the exercise rehabilitation willingness, health behaviors and coping styles. In addition, it is of great significance for promoting the rehabilitation of patients.
Objective To analyze the application value of swallowing function therapeutic instrument in dysphagia after stroke. Methods Stroke patients with dysphagia treated in the Department of Rehabilitation Medicine of Qinghai University Affiliated Hospital between July 2018 and April 2020 were selected. The patients were randomly divided into experimental group and control group. The control group was treated with comprehensive rehabilitation treatment, and the experimental group was treated with comprehensive rehabilitation treatment and swallowing function therapeutic instrument. The improvement of dysphagia and the changes of clinical indexes were observed in the two groups. Results A total of 100 patients were included, with 50 patients in each group. Before the intervention, there was no significant difference between the two groups in Standardized Swallowing Assessment (SSA), video fluoroscopy swallowing study (VFSS), ultrasonic exercise amplitude and duration (P>0.05). After 4 weeks of intervention, the SSA score, VFSS score, ultrasonic exercise amplitude and duration of the two groups were improved compared with those before intervention (P<0.05), and the experimental group was better than the control group (P<0.05). The improvement of dysphagia between the two groups was statistically significant (Z=?2.452, P=0.014). The total effective rate of dysphagia improvement in the experimental group (92.00%) was higher than that in the control group (82.00%), but there was no significant difference between the two groups (χ2=2.210, P=0.137). Conclusion The application of swallowing function therapeutic instrument in the adjuvant treatment of dysphagia after stroke is helpful to improve the clinical symptoms of patients and obtain ideal therapeutic effect, which is worth popularizing.

Objective To investigate the incidence of perioperative stroke in elderly patients (≥65 years) undergoing offpump coronary artery bypass grafting (OPCAB) versus onpump coronary artery bypass grafting (CABG). Methods WTBZ]We electronically searched PubMed (from 1966 to 2010), Cochrane Library (Issue 12, 2010), EMbase (from 1974 to 2010), CNKI (Chinese, from 1997 to 2010), CBM (Chinese, from 1989 to 2010), and manually searched some journals to collect published or grey literatures of clinical researches on comparison between OPCAB and CABG for elderly patients in the incidence of perioperative strokes. We assessed the methodology quality of included researches and extracted data to conduct metaanalysis by RevMan 5.0 software. Four subgroups (aged 65 to 70 years, 70 to 75 years, 75 to 80 years, and older than 80 years) according to the age of the patients, and subgroups according to the study design were analyzed respectively. Sensitivity analysis was conducted by deleting the studies of low quality. Results We finally identified 17 studies including 5 historical cohort studies and 12 case control studies. No randomized controlled trial was searched. A total of 7 275 patients including 2 521 (34.65%) in the OPCAB group and 4 754 (65.35%) in the CABG group were identified. The metaanalyses of historical cohort study subgroup and case control study subgroup showed statistical difference in stroke incidence between the OPCABG and CABG groups with OR 0.25 and 95%CI 0.10 to 0.62,and with OR 0.25 and 95%CI 0.15 to 0.41,respectively. Statistical difference was tested in three age subgroups (70 to 75 years, 75 to 80 years, and elder than 80 years) and the OR (95%CI) value was 0.35 (0.21, 0.59), 0.14 (0.04, 0.54), and 0.09 (0.02, 0.38),respectively. The difference of stroke incidence between OPCAB and CABG patients in all the three subgroups was significant, while there was no statistical difference in the subgroup aged 65 to 70 years with OR 0.10 and 95%CI 0.01 to 1.68. The sensitvity analysis showed that metaanalysis was stable in case control study subgroup, was not stable in historical cohort study subgroup. Conclusions OPCAB may reduce incidence of perioperative stroke in elderly patients. However, it still needs to be confirmed by more multicenter, largesample, and randomized doubleblind controlled trials in the future.
