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.
ObjectiveTo systematically review the efficacy of different stimulation modalities of repetitive transcranial magnetic stimulation (rTMS) combined with SSRI in improving depressed mood after stroke using network meta-analysis. MethodsThe PubMed, EMbase, Cochrane Library, Web of Science, CNKI, VIP, CBM and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to October 1, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Network meta-analysis was then performed by using R 4.2.1software. ResultsA total of 25 RCTs involving 2 152 patients were included. Four types of rTMS stimulation combined with SSRIs were included: high-frequency stimulation of the left dorsolateral prefrontal (l-DLPFC), low-frequency stimulation of l-DLPFC, low-frequency stimulation of the right dorsolateral prefrontal (r-DLPFC), and low-frequency stimulation of the bilateral DLPFC. The results of the network meta-analysis showed that the effect of combining four stimulation methods with SSRI in treating depression was better than that of SSRI alone (P<0.05). Probability sorting results showed that low-frequency stimulated bilateral DLPFC (88.9%) > low-frequency stimulated l-DLPFC (63.1%) > high-frequency stimulation l-DLPFC (57.1%) > low-frequency stimulation r-DLPFC (40.4%). There was no statistically significant difference in the incidence of adverse reactions between the four stimulation methods combined with SSRI and the use of SSRI alone (P>0.05). Conclusion?rTMS combined with SSRIs is better than SSRIs alone in improving depressed mood after stroke. Low-frequency rTMS stimulation of bilateral DLPFC may be the best. Meanwhile, the safety of different stimulation methods is good.
ObjectiveTo explore the differences of rehabilitation clinical characteristics between youth stroke patients and middle and old age stroke patients, to provide references for secondary prevention and personalized rehabilitation treatment for youth stroke.MethodsFrom May 2016 to October 2019, stroke inpatient in the Department of Rehabilitation Medicine of Huashan Hospital of Fudan University were included. Patients were divided into youth group and middle and old age group according to their age. The clinical characteristics of the two groups during the rehabilitation period were analyzed.ResultsA total of 271 patients were included, including 70 in the youth group and 201 in the middle and old age group. The proportion of patients with hypertension (85.07% vs. 71.43%), diabetes (34.83% vs. 17.14%) and infection (20.90% vs. 8.57%) in the middle and old age group were higher than those in the youth group (P<0.05). The proportion of patients with hemorrhagic stroke (71.43% vs. 32.84%), history of stroke surgery (54.29% vs. 13.43%), epilepsy secondary to stroke (31.43% vs. 4.48%) and overweight/obesity (57.14% vs. 42.79%) in the youth group were higher than those in the middle and old age group (P<0.05). There was no significant difference in the proportion of gender, cognitive impairment, and thinness between the two groups (P>0.05). Among patients whose disease course was within 1 month at the time of admission, there was no significant difference in Brunnstrom stage of upper limbs-hands-lower limbs between the two groups (P>0.05). The scores of Berg Balance Scale (Z=?2.493, P=0.013) and Barthel Index (Z=?2.527, P=0.012) in the youth group were higher than those in the middle and old age group. Among patients whose disease course was between 1 month and 3 months at the time of admission, there was no significant difference in Brunnstrom stage of upper limbs-hands-lower limbs and Barthel Index between the two groups (P>0.05). The scores of Berg Balance Scale in the youth group were higher than those in the middle and old age group (Z=?2.004, P=0.045). Among patients whose disease course was more than 3 months at the time of admission, there was no significant difference in the scores of Berg Balance Scale, Barthel Index, and Brunnstrom stage of upper limbs-hands-lower limbs between the two groups (P>0.05).ConclusionsFor youth stroke patients, weight control is very important, and it is necessary to pay close attention to whether there are seizures. In the case of patients with stable vital signs in the early stage of the disease, more active rehabilitation treatment can be given.
ObjectiveTo systematically review the outcomes reported in clinical trials of post-stroke dysarthria.MethodsPubMed, The Cochrane Library, EMbase, CNKI, Sinomed, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of post-stroke dysarthria from inception to December 6th, 2019. Two reviewers independently screened literature, extracted data and analyzed outcomes using qualitative method.ResultA total of 112 RCTs involving 39 outcomes (therapeutic effect assessment outcomes and safety outcomes) were included. The top 4 outcomes were the Frenchay dysarthria assessment scale, the dysarthria examination method developed by the Chinese rehabilitation center, the evaluation of the speech therapists or clinicians and GRBAS.ConclusionsCurrent evidence shows that there is no acceptable outcomes for post-stroke dysarthria. It is recommended to improve the suitable assessment scale for Chinese to improve quality of studies on post-strohe dysarthria.
ObjectiveTo evaluate the performance and safety of a novel device for left atrial appengdage (LAA) closure in dogs.
MethodsThrough the fourth left intercostal, the LAA clips were implanted at the base of LAA in six dogs. Macroscopic pathology, histopathology and biological detection were performed at 7 d, 60 d, 90 d, 180 d after implan-tation respectively.
ResultsThe devices were all successfully implanted at the base of LAA. There is no transposition of the LAA clips. Complete fibrosis and atrophy of LAA occurred at 60 d after implantation. LAA closure was completed with a new endothelial tissue layer developed on the occluded orifice of the left atrium after 60 d after implantation. The level of atrial natriuretic peptide did not decrease significantly after the device implantation (275.64±60.00 pg/ml vs. 248.34±56.10 pg/ml, P=0.529).
ConclusionThe novel device for LAA closure achieved easy, reliable and safe closure of the LAA in canine model.
ObjectiveTo systematically review the efficacy of early physical rehabilitation for patients with stroke-induced hemiplegia.
MethodsDatabases including PubMed, Web of Knowledge, The Cochrane Library (Issue 7, 2014), EMbase, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about early physical rehabilitation for patients with stroke-induced hemiplegia from inception to 1st August 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, metaanalysis was performed using RevMan 5.2 software.
ResultsA total of 6 RCTs were included. The results of metaanalysis showed that, after 1 month of treatment, the Fugl-Meyer scores (MD=18.02, 95%CI 6.24 to 29.80, P=0.003) and BI scores (MD=32.32, 95%CI 24.28 to 40.36, P<0.000 01) in the early physical rehabilitation group were higher than that in the conventional rehabilitation group. But after 3 months of treatment, there were no statistical differences between two groups in the proportion of patients with 0-2 MRS scores, mortality and the incidence of complications.
ConclusionCurrent evidence shows that early physical rehabilitation can effectively improve the limb motor function and daily living ability in patients with stroke-induced hemiplegia. However, due to the limited quantity and quality of the include studies, more large-scale, high quality RCTs are needed to verify the above conclusion.
ObjectiveConstructing a prediction model for seizures after stroke, and exploring the risk factors that lead to seizures after stroke. MethodsA retrospective analysis was conducted on 1 741 patients with stroke admitted to People's Hospital of Zhongjiang from July 2020 to September 2022 who met the inclusion and exclusion criteria. These patients were followed up for one year after the occurrence of stroke to observe whether they experienced seizures. Patient data such as gender, age, diagnosis, National Institute of Health Stroke Scale (NIHSS) score, Activity of daily living (ADL) score, laboratory tests, and imaging examination data were recorded. Taking the occurrence of seizures as the outcome, an analysis was conducted on the above data. The Least absolute shrinkage and selection operator (LASSO) regression analysis was used to screen predictive variables, and multivariate Logistic regression analysis was performed. Subsequently, the data were randomly divided into a training set and a validation set in a 7:3 ratio. Construct prediction model, calculate the C-index, draw nomogram, calibration plot, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) to evaluate the model's performance and clinical application value. ResultsThrough LASSO regression, nine non-zero coefficient predictive variables were identified: NIHSS score, homocysteine (Hcy), aspartate aminotransferase (AST), platelet count, hyperuricemia, hyponatremia, frontal lobe lesions, temporal lobe lesions, and pons lesions. Multivariate logistic regression analysis revealed that NIHSS score, Hcy, hyperuricemia, hyponatremia, and pons lesions were positively correlated with seizures after stroke, while AST and platelet count were negatively correlated with seizures after stroke. A nomogram for predicting seizures after stroke was established. The C-index of the training set and validation set were 0.854 [95%CI (0.841, 0.947)] and 0.838 [95%CI (0.800, 0.988)], respectively. The areas under the ROC curves were 0.842 [95%CI (0.777, 0.899)] and 0.829 [95%CI (0.694, 0.936)] respectively. Conclusion These nine variables can be used to predict seizures after stroke, and they provide new insights into its risk factors.
Objective
To carry out the systematic clinical management to reduce the incidence of femoral pseudoaneurysm after interventional treatment.
Methods
A historical controlled study was used to compare the management effect before (from October 2012 to October 2013) and after (from March 2014 to March 2015) the application of doctor-nurse integrated systematic clinical management mode. This work mode enhanced cooperation between doctors and nurses, formed the clinical path for nursing workflows and contingency plans, and strengthened specialized education and training for nurses.
Results
After the implementation of systematic clinical management, the incidence of femoral pseudoaneurysm was significantly lower than before (1.0% vs. 2.7%), and the difference was statistically significant (P<0.05).
Conclusions
The systematic clinical management, carrying out in the doctor-nurse integration mode, can improve the quality of nursing and reduce the incidence of femoral pseudoaneurysm. And the management model has achieved remarkable results. So it is worth to be applied in the clinical practices.
In 2007, the findings from clinical trials on stroke treatment have been both encouraging and disappointing. In order to interpret the challenges and opportunity in evidence-based stroke practice, we reviewed several major clinical trials in stroke that were published last year. It revealed that we should strengthen the evidence base for acute stroke care by conducting more high-quality randomized controlled trials and by increasing the energy, resources and manpower available for these trials.
