Focal T2 and FLAIR hyperintensities within the infarcted area: A suitable marker for patient selection for treatment? PLoS One 2017; 12:e0185158.

Abstract
Background and purpose Some authors use FLAIR imaging to select patients for stroke treatment. However, the effect of hyperintensity on FLAIR images on outcome and bleeding has been addressed in only few studies with conflicting results. Methods 466 patients with anterior circulation strokes were included in this study. They all were examined with MRI before intravenous or endovascular treatment. Baseline data and 3 months outcome were recorded prospectively. Focal T2 and FLAIR hyperintensities within the ischemic lesion were evaluated by two raters, and the PROACT II classification was applied to assess bleeding complications on follow up imaging. Logistic regression analysis was used to determine predictors of bleeding complications and outcome and to analyze the influence of T2 or FLAIR hyperintensity on outcome. Results Focal hyperintensities were found in 142 of 307 (46.3%) patients with T2 weighted imaging and in 89 of 159 (56%) patients with FLAIR imaging. Hyperintensity in the basal ganglia, especially in the lentiform nucleus, on T2 weighted imaging was the only independent predictor of any bleeding after reperfusion treatment (33.8% in patients with vs. 18.2% in those without; p = 0.003) and there was a non-significant trend for more bleedings in patients with FLAIR hyperintensity within the basal ganglia (p = 0.069). However, there was no association of hyperintensity on T2 weighted or FLAIR images and symptomatic bleeding or worse outcome. Conclusion Our results question the assumption that T2 or FLAIR hyperintensities within the ischemic lesion should be used to exclude patients from reperfusion therapy, especially not from endovascular treatment.

Abstract
BACKGROUND Soluble CD40 ligand (sCD40L) is associated with inflammation. This study aimed to assess the prognostic value of sCD40L for clinical outcomes of acute intracerebral hemorrhage (ICH) patients. MATERIALS AND METHODS The serum sCD40L levels of 110 patients and 110 age- and gender-matched healthy controls were measured using sandwich immunoassays. The relationships between serum sCD40L levels and 1-week mortality, 6-month mortality, 6-month overall survival, 6-month unfavorable outcome (modified Rankin Scale score >2), and ICH severity including hematoma volume and National Institutes of Health Stroke Scale (NIHSS) score were assessed using multivariate analysis. RESULTS Compared with healthy controls, ICH patients had higher serum sCD40L levels. Serum sCD40L levels were correlated positively with hematoma volumes and NIHSS scores using a multivariate linear regression. Multivariate analysis results indicated that sCD40L was identified an independent predictor of 1-week mortality, 6-month mortality, 6-month unfavorable outcome and 6-month overall survival. sCD40L also showed high predictive performances for 1-week mortality, 6-month mortality and 6-month unfavorable outcome based on receiver operating characteristic curve. CONCLUSIONS Elevated serum sCD40L levels are independently associated with ICH severity and clinical outcomes. And sCD40L has potential to be a good prognostic biomarker of ICH.
