PURPOSE Chronic systemic inflammation is prevalent in patients with chronic kidney disease (CKD) and is linked to the development of cerebrovascular disease. In this study, we explored the association between the unstable plaques and preoperative CKD in patients who underwent carotid endarterectomy (CEA)/carotid artery stenting (CAS). Furthermore, this study also aimed to explore whether there is a difference in the aggravation of renal function with the presence of stable or unstable plaques. PATIENTS AND METHODS The study included 90 patients who underwent CEA/CAS for carotid artery stenosis. Multivariate analysis was performed to determine the risk factors for CKD. Kaplan-Meier estimation was employed to evaluate the aggravation of renal function following CEA/CAS. RESULTS Multivariate analysis revealed that contralateral carotid occlusive disease (odds ratio [OR], 4.45; 95% confidence interval [CI], 1.36-14.6), and T1 high-intensity carotid plaque (OR, 3.26; 95% CI, 1.2-8.86) were independent factors of CKD. Kaplan-Meier estimation demonstrated a higher aggravation of renal function in the T1 high-intensity group compared to those in the iso-intensity (P =.03). Following CEA/CAS, the time until aggravation of renal insufficiency was 12.0 ± 9.4 months in the T1 high-intensity group and 24.5 ± 9.6 months in the iso-intensity group (P =.03). CONCLUSIONS This study demonstrated that contralateral carotid artery stenosis and T1 high-intensity plaques are more frequently observed in patients with CKD. T1 high-intensity carotid plaque is well linked to CKD development in future. BACKGROUND Myocardial injury is a complication of stroke associated with unfavorable outcome, with the elevation of cardiac troponin as the most sensitive marker. In this study, we aimed at investigating the association between statin pretreatment and poststroke myocardial injury. METHODS Six hundred seventy-one patients diagnosed as acute ischemic stroke were enrolled. According to the histories of statin pretreatment before stroke, patients were categorized into nonstatin (n = 474) and statin groups (n = 197), with the latter further divided into low-dosage, standard-dosage, and high-dosage subgroups according the dosages of statins. The level of troponin-T was tested and troponin-T level ≥14 ng/l was identified to indicate the presence of myocardial injury. The level of troponin-T and the prevalence of myocardial injury was compared between groups. [https://www.selleckchem.com/products/sitagliptin.html Sitagliptin] Logistic regression was used to identify the effect of statin pretreatment for the presence of post-stroke myocardial injury. RESULTS Statin users had lower levels of troponin-T after stroke, with the level of troponin-T being the lowest in the high-dosage subgroup. The results of logistic regression showed that statin pretreatment and high-dosage statin were independent protective factors for the elevation of troponin-T levels. CONCLUSIONS Statin pretreatment might be associated with the decreased myocardial injury after ischemic stroke. BACKGROUND Few prospective cohort studies collect detailed information on stroke characteristics among individuals who experience ischemic stroke, including white matter hyperintensity volume, and thus cannot explore how prospectively collected biomarkers prior to the stroke influence white matter hyperintensity volume. We explored the association between a large panel of prospectively collected lipid and inflammatory biomarkers and white matter hyperintensity volume among participants in the Women's Health Study with incident ischemic stroke. METHODS Among Women's Health Study participants with first ischemic stroke who had baseline serum biomarkers and available magnetic resonance imaging, we measured white matter hyperintensity volume using a validated semi-automated method. Linear regression was used to explore the associations between biomarkers and log-transformed white matter hyperintensity volume. RESULTS After multivariate adjustment, a 1% increment in HbA1c% was associated with an increase in white matter hyperintensity volume (P value = .05). Evidence of a nonlinear association between high density lipoprotein cholesterol levels and ApoA1 levels with white matter hyperintensity volume was noted (P values for nonlinearity = .01 and .001, respectively). No other biomarkers were significantly associated with white matter hyperintensity volume. CONCLUSIONS Chronic hyperglycemia as evidenced by HbA1c levels measured years prior to stroke is associated with white matter hyperintensity volume at the time of stroke. Additional research is needed to explain why low levels of high density lipoprotein cholesterol levels and ApoA1 may be associated with similar white matter hyperintensity volume as high levels. OBJECTIVE The purpose of our study is to evaluate the efficacy of paroxetine in poststroke depression (PSD) patients by conducting a meta-analysis. METHODS We searched Web of Science (science and social science citation index), PubMed, the Cochrane Central Register of Controlled Trials, Embase up to August 2019. Randomized controlled trials that paroxetine compared to other antidepressants or control treatments as monotherapy for patients with PSD. RESULTS This review identified a total of 4 studies including 212 patients. This meta-analysis presented that paroxetine exhibits beneficial efficacy than routine treatment in PSD patients in terms of the reducing score of Hamilton Depression Scale (HAMD). Control treatment is more effective than paroxetine. No significant advantage was found with paroxetine. CONCLUSIONS The efficacy of paroxetine maybe not very significant compared to other pharmacological and nonpharmacological interventions. Further high quality and large sample size studies are needed to evaluate the efficacy and safety of paroxetine in treating PSD in future. BACKGROUND It has been proposed that the presence of a multiple territory stroke pattern (MTSP) on brain imaging may aid identification of patients with covert atrial fibrillation (AF). However, it is uncertain whether this association holds true among patients treated with intravenous recombinant tissue plasminogen activator (rtPA) because clot fragmentation may affect MTSP prevalence. METHODS/DESIGN Retrospective analysis of 149 acute ischemic stroke patients treated with intravenous rtPA who underwent brain MRI. Presence of multiple acute infarctions on brain MRI that involved more than one vascular territory was considered to denote MTSP. Stroke etiology was categorized as nonembolic, cardioembolic (CES), and embolic stroke of undetermined source (ESUS). RESULTS In the entire cohort, subjects with CES and ESUS had significantly more often an MTSP than subjects with other determined stroke mechanism (P= .007). Although numerically relatively more patients had an MTSP as compared to a non-MTSP among subjects with CES (52% versus 33.
