Objective To explore the impact of gender difference in 90-day outcomes after mechanical thrombectomy for acute cerebral infarction. Methods A prospective registration, observational, and retrospective analysis study was carried out. Patients with acute cerebral infarction who were admitted to the Department of Neurology of the First Affiliated Hospital of Chengdu Medical College and the Department of Neurology of Nanjing First Hospital between June 2015 and June 2019 were collected. Patients were divided into two groups based on gender. The detailed demographic, laboratory examination, imaging examination and clinical data were collected. Then, the data were analyzed using univariate and multivariate logistic regression analyses. Results A total of 298 patients were included. Among them, there were 185 males and 113 females. The differences in age, smoking, atrial fibrillation, using antiplatelet drugs before stroke, TOAST classification, and involved cerebrovascular sites between the two groups were statistically significant (P<0.05), and there was no statistically significant difference in other baseline data between the two groups (P>0.05). The results of univariate logistic regression analysis showed that the rate of 90-day favourable outcome of female patients was lower than that of male patients [odds ratio (OR)=0.462, 95% confidence interval (CI) (0.275, 0.775), P=0.030]. The results of multivariate logistic regression analysis showed that, after adjusting for confounding factors, there was no independent correlation between gender and the 90-day favourable outcome of patients with acute cerebral infarction who underwent mechanical thrombectomy [OR=1.511, 95% CI (0.745, 3.066), P=0.253]. Conclusion The gender has no significant effect on the 90-day favourable outcome of acute cerebral infarction patients treated with mechanical thrombectomy.

ObjectiveTo systematically review the association between migraine and lacunar infarcts on MR image.MethodsPubMed, EMbase, The Cochrane Library, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials, cohort studies and cross-sectional studies on the association between migraine and lacunar infarcts from inception to March 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 5 studies involving 5 104 participants were included. The results of meta-analysis showed that: there were no significant associations of migraine (OR=0.93, 95%CI 0.78 to 1.12, P=0.470) and aura (OR=1.10, 95%CI 0.89 to 1.36, P=0.390) with lacunar infarcts on MR image. Subgroup analysis by age, presence or absence of aura showed no significant tendency.ConclusionsThere is no significant relationship between migraine and lacunar infarcts. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To explore the predictive value of superoxide dismutase (SOD) and serum amyloid A (SAA) in short-term poor prognosis in patients with lacunar infarction. Methods The clinical data of 185 patients who were diagnosed with lacunar infarction in the Second Affiliated Hospital of Wannan Medical College between January 1st and December 31st, 2021 were analyzed retrospectively. According to the modified Rankin Scale (mRS) score 3 months after discharge, the patients were divided into the good prognostic group (mRS≤2) and the poor prognostic group (mRS>2). Multiple logistic regression was used to analyze the independent risk factors of the short-term adverse prognosis of patients with lacunar infarction, and a risk prediction model (nomograph) was constructed. The predictive efficacy of SOD, SAA and nomograph for poor prognosis was analyzed by using the receiver operating characteristic curve. Calibration curve and decision curve analysis were used to evaluate the differentiation and clinical application value of the model. Results A total of 185 lacunar cerebral infarction patients with a mean age of (68.26±10.77) years were enrolled in this study, among whom 80 (43.2%) were males and 39 (21.1%) had adverse prognosis. Multiple logistic regression analysis showed that systolic blood pressure [odds ratio (OR)=1.028, 95% confidence interval (CI) (1.004, 1.052), P=0.021], diabetes [OR=4.939, 95%CI (1.703, 14.320), P=0.003], SAA [OR=1.089, 95%CI (1.052, 1.128), P<0.001], apolipoprotein B [OR=7.647, 95%CI (2.186, 26.753), P=0.001] were independent risk factors for poor prognosis in lacunar infarction patients, while the level of SOD [OR=0.979, 95%CI (0.965, 0.994), P=0.006] was a protective factor. The area under the curve of the nomograph for predicting the short term poor prognosis was 0.874 [95%CI (0.812, 0.936), P<0.001]. The goodness-of-fit test with the calibration curve indicated that the prediction probability was consistent with the actual occurrence probability (Hosmer-Lemeshow test P=0.295), and the decision curve indicated that the nomograph had good clinical application value. Conclusion SAA and SOD have good predictive value for short-term adverse prognosis of lacunar cerebral infarction patients, and the nomograph constructed based on them has a good differentiation and consistency, which can provide a basis for clinicians to evaluate the prognosis of lacunar cerebral infarction patients.
Cerebral small vessel disease is a common neurological disease, including acute and non-acute categories. With the development of neuroimaging, cerebral small vessel disease has attracted substantial attention in recent years. However, the categories and concepts of cerebral small vessel disease and the related imaging markers usually confuse people. The purpose of this study was to discuss the relationships among acute and non-acute cerebral small vessel disease and the imaging markers, so as to improve the understanding of cerebral small vessel disease, and to shed light on clinical practice and research.
Ischemic lesions, lacunar infarcts and leukoaraiosis on head CT or MRI are commonly detected in patients with non-specific symptoms such as dizziness and headache or people undergoing healthy physical examinations. Although these imaging findings are mostly related to vascular disease, especially cerebral small vessel disease, it does not mean that long-term use of antiplatelet drugs and statins are required. On the basis of literature review and clinical experiences, the article points out that the treatment methods for such manifestations include determining whether these lesions are vascular lesions, searching for risk factors or causes such as aging, hypertension, diabetes mellitus, vascular stenosis, and psychological factors, and taking strategies for the corresponding prevention and management, provides a reference for the appropriate diagnosis and treatment of these imaging manifestations in clinical practice.
Objective To compare the risk factors between multiple cerebral infarction (MCI) and single cerebral infarction (SCI). This would be beneficial for carrying out corresponding prevention and treatment. Methods We prospectively registered consecutive cases of ischemic stroke in the neurological wards and divided them into two groups: MCI group and SCI group according to their clinical and imaging data. Firstly, the single variable analyses of 24 factors that could be related to the onset of MCI were conducted, and then the multivariate non-condition stepwise logistic regression was performed. Results Significant differences were noted between MCI group and SCI group in terms of age, gender, hpertension, diabetes, heart valvular disease, smoking, cerebral infarction history and first systolic blood pressure after admission. The logistic regression analyses showed that factors of age (OR=1.014, 95%CI 1.003 to 1.026), hypertension (OR=1.566, 95%CI 1.185 to 2.068), smoking (OR=1.473, 95%CI 1.052 to 2.061), cerebral infarction history (OR=1.948, 95%CI 1.326 to 2.864) were independent risk factors for MCI. Conclusion Compared to SCI, age, hypertension, smoking and cerebral infarction history were independent risk factors for MCI patients.
