SII was the independent variable, and stroke was the dependent variable. Weighted logistic regression models were employed to analyze their relationship. The nonlinear association between SII and stroke was examined using the restricted cubic spline (RCS) method in subgroups stratified by smoking status, hypertension, and dietary inflammatory index. Weighted Kaplan-Meier curves and Cox regression analysis were used to investigate the association of SII with all-cause mortality and cardiovascular disease (CVD) mortality.</p><p><strong>Results: </strong>A total of 22,107 samples were included in this study. Weighted logistic regression analysis showed a significant correlation between SII and stroke (OR: 1.53, 95% CI: 1.22-1.92, P <0.001). The stratified analysis revealed that interactions of smoking status and hypertension with SII, respectively, had significant impacts on stroke risk. A remarkable positive link between SII and stroke risk (OR>1, P <0.05) was observed in the crude model (unadjusted for confounding factors), model I (adjusted for demographic characteristics), and model II (adjusted for all confounding factors). RCS analysis displayed a remarkable nonlinear positive correlation between SII and stroke risk only in the \"now smoking\" population ( P -nonlinear<0.05) after adjusting for all confounding factors. In the overall sample population, Kaplan-Meier curves indicated that individuals in the highest quartile of SII had the highest risk of all-cause mortality and CVD mortality (log-rank test P <0.05). Samples with proinflammatory dietary habits had considerably higher risks of all-cause mortality and CVD mortality compared with those with anti-inflammatory dietary habits (log-rank test P <0.05). Multivariable-adjusted Cox regression models showed significantly increased all-cause mortality and CVD mortality rates in the highest quartile of SII compared with the lowest quartile.</p><p><strong>Conclusions: </strong>SII levels were considerably positively linked to stroke risk, particularly in the \"now smoking\" population.

BA dolichoectasia was categorized according to Smoker criteria. An additional criteria of BA laterality angle was described. The length between the infarct long-axis and BA cross-sectional center was measured, and named as \"branch length (BL).\" ECW was defined as any increase in NIHSS.</p><p><strong>Results: </strong>ECW was seen in 22 (15%) patients. Univariate analysis documented a higher female ratio (22% vs. 10%, P=0.007), higher atrial fibrillation (18% vs. 7%, P=0.067), more common anteromedial infarct location (77% vs. 49%, P=0.025), and Smoker category-3 BA height (32% vs. 10%, P=0.043) in these patients. In anteromedial infarcts, BL was longer (8.3 vs. 6.1 mm, P=0.052), and reaching to significance in those located at mid-up/upper pontine level (1.22 vs. 0.62 mm, P=0.006). BL >4.4 mm showed an acceptable discriminatory capacity for ECW with an AUC of ROC: 0.615 (95% CI: 0.511-0.712). A regression model indicated female sex (β±SE=1.129±0.551, P=0.040), BL (per 4.4 mm, β±SE=1.236±0.614, P=0.044), and BA height-category-3 (β±SE=1.711±0.645, P=0.008) as independent predictors for ECW.</p><p><strong>Conclusions: </strong>Some features of basilar dolichoarteriopathy, such as the extreme location of the height of the BA tip and the length of the involved perforator in the prepontine cistern, may be predictors of early clinical worsening in acute isolated pontine infarcts.</p>","PeriodicalId":49758,"journal":{"name":"Neurologist","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142819817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
