- BACKGROUND AND PURPOSE: In SPARCL, treatment with atorvastatin 80 mg daily reduced stroke risk in patients with recent stroke or TIA and no known coronary heart disease by 16% versus placebo over 4.9 years of follow-up. The purpose of this secondary analysis was to determine whether men and women similarly benefited from randomization to statin treatment. METHODS: The effect of sex on treatment-related reductions in stroke and other cardiovascular outcomes were analyzed with Cox regression modeling testing for sex by treatment interactions. RESULTS: Women (n=1908) constituted 40% of the SPARCL study population. At baseline, men (n=2823) were younger (62.0+/-0.21 versus 63.9+/-0.27 years), had lower systolic BPs (138.1+/-0.35 versus 139.5+/-0.47 mm Hg), higher diastolic BPs (82.2+/-0.20 versus 81.0+/-0.25 mm Hg), more frequently had a history of smoking (73% versus 38%), and had lower total cholesterol (207.0+/-0.54 versus 218.9+/-0.67 mg/dL) and LDL-C levels (132+/-0.45 versus 134+/-0.57 mg/dL) than women. Use of antithrombotics and antihypertensives were similar. After prespecified adjustment for region, entry event, time since event, and age, there were no sex by treatment interactions for the combined risk of nonfatal and fatal stroke (treatment Hazard Ratio, HR=0.84, 95% CI 0.68, 1.02 in men versus HR=0.84, 95% CI 0.63, 1.11 in women; treatment x sex interaction P=0.99), major cardiac events (HR=0.61, 95% CI 0.42, 0.87 in men versus HR=0.76, 95% CI 0.48, 1.21 in women; P=0.45), major cardiovascular events (HR=0.78, 95% CI 0.65, 0.93 in men versus HR=0.84, 95% CI 0.65, 1.07 in women; P=0.63), revascularization procedures (HR=0.50, 95% CI 0.37, 0.67 in men versus HR=0.76, 95% CI 0.46, 1.24 in women; P=0.17), or any CHD event (HR=0.54, 95% CI 0.41, 0.72 in men versus 0.67 95% CI 0.46, 0.98 in women; P=0.40). CONCLUSIONS: Stroke and other cardiovascular events are similarly reduced with atorvastatin 80 mg/d in men and women with recent stroke or TIA.

- Objective: To determine the association between admission blood glucose and outcome in ischemic stroke patients treated with thrombolysis. Design: A prospective, open, multinational, observational study. Setting: An ongoing Internet-based, academic-driven, interactive thrombolysis register. Patients: Between 2002 and 2007, 16 049 patients were recorded in the SITS-ISTR. Main Outcome Measure: Blood glucose was recorded at admission. Blood glucose was divided into the following categories: less than 80,80-120 (reference range), 121-140, 141-160, 161-180, 181-200, and greater than 200 mg/dL. Outcomes were mortality and independence (modified Rankin Scale score of 0-2) at 3 months and symptomatic intracerebral hemorrhage (SICH) (National Institutes of Health Stroke Scale deterioration >= points within 24 hours and type 2 parenchymal hemorrhage). Results: In multivariable analysis, blood glucose as a continuous variable was independently associated with a higher mortality (P < .001), lower independence (P < .001), and an increased risk of SICH (P = .005). Blood glucose greater than 120 mg/dL as a categorical variable was associated with a significantly higher odds for mortality (odds ratio [OR], 1.24; 95% confidence interval [Cl], 1.07-1.44; P = .004) and a lower odds for independence (OR, 0.58; 95% CI, 0.48-0.70; P < .001), and blood glucose from 181 to 200 mg/dL was associated with an increased risk of SICH (OR, 2.86; 95% CI, 1.69-4.83; P < .001) compared with the reference level. The trends of associations between blood glucose and outcomes were similar in patients with diabetes (17%) or without such history, except for mortality (P = .23) and SICH (P = .06) in which the association was not statistically significant in patients with diabetes. Conclusions: Admission hyperglycemia was an independent predictor for poor outcome after stroke/thrombolysis, though SICH rates did not increase significantly until reaching 180 mg/dL. These results suggest that tight control of blood glucose may be indicated in the hyperacute phase following thrombolysis. Randomized trial data are needed.

- Background: Scientific reviewing is a voluntary process to determine if a manuscript deserves publication. REVIEW means: Responsibly Evaluate, Verify and Improve the manuscript, Educate the authors and editors, and Weigh your expert opinion against the submitted work. Provide your review in a respectful, unbiased and timely manner. Review Methods: Make sure editors know about your willingness to review and your particular area(s) of expertise. If you find yourself in a conflict of interest, decline to participate in reviewing. If you accept, complete reviews on time. Determine and rate (1) the methodological validity, (2) originality, (3) significance of findings, (4) the style and clarity of presentation and (5) the findings' interest to the readership of the journal for which you are asked to review a manuscript. Specifically evaluate (6) if the results support any claims or conclusions made and, most importantly, (7) if the abstract correctly reflects the full content of a manuscript. Summarize your review in specific comments to the authors. Make recommendations whether to accept, revise or reject the manuscript to the editor only. Review Results: Start with a brief summary of the manuscript's subject, strengths and key findings/claims. Present your specific criticisms and suggestions in numbered lists for the authors to address. Never use demeaning and offensive words or sarcasm since, in the first place, this reflects upon your own ethics and integrity as well as upon the journal's. Use a constructive tone, and if you see any deficiencies, educate the authors in a respectful manner so that, even if a manuscript is rejected, they will learn from you, improve the manuscript or conduct a better study in the future. Also include ratings from 1 to 7 in your comments to the authors, as far as they are relevant and may explain your final decision. Conclusions: Judge others as you would like to be judged yourself. We hope these suggestions serve to help new reviewers and refresh the willingness of battle-hardened veterans to continuously serve the medical literature. Copyright (C) 2009 S. Karger AG, Basel

- <i>Background:</i> Age-related white matter changes (ARWMC), seen on neuroimaging with high frequency in older people, are thought to be consequent to the effect of vascular risk factors and vascular diseases including hypertension and stroke. Among the proofs conventionally required for a factor to be considered a risk factor for a definite pathology, there is the demonstration of a trend in risk exposure related to disease severity. We sought whether such a trend existed in the association of vascular risk factors or comorbidities with the severity of ARWMC aiming particularly at further elucidating the relative roles of hypertension and stroke in this regard. <i>Methods:</i> The LADIS (Leukoaraiosis and Disability) Study is evaluating the role of ARWMC as an independent determinant of the transition to disability in the elderly. Six hundred and thirty-nine nondisabled subjects (mean age 74.1 ± 5.0, M/F: 288/351) with ARWMC of different severity grades on MRI (mild, moderate, or severe according to the Fazekas scale) were assessed at baseline for demographics, vascular risk factors, and comorbidities, and are being followed up for 3 years. <i>Results:</i> Age, frequency of hypertension and history of stroke increased along with increasing ARWMC severity independently of other factors. For hypertension, however, this occurred only in subjects without a stroke history, while for stroke history, it mainly depended on lacunar stroke. The amount of cigarettes smoked and the interaction between hypercholesterolemia and smoking predicted only the most severe ARWMC grade. <i>Conclusions:</i> The LADIS Study confirms that age, hypertension and lacunar strokes are the major determinants of ARWMC. Smoking and hypercholesterolemia provide additional risk.

- A patent foramen ovale (PFO) is disproportionately prevalent in patients with cryptogenic stroke. Without alternative explanations, it is frequently considered to be causative. A detailed stratification of these patients may improve the identification of incidental PFO.We investigated the PFO prevalence in 3497 transient ischemic attack and ischemic stroke patients aged 18 to 55 years in the prospective multicenter SIFAP1 study (Stroke in Young Fabry Patients 1) using the ASCO classification. Patients without an obvious cause for transient ischemic attack/stroke (ASCO 0) were divided into subgroups with and without vascular risk factors (ASCO 0+ and 0-). In addition, we looked for PFO-related magnetic resonance imaging lesion patterns.PFO was identified in 25% of patients. Twenty percent of patients with a definite or probable cause of transient ischemic attack/stroke (≥1 grade 1 or 2 ASCO criterion; n=1769) had a PFO compared with 29% of cryptogenic stroke patients (ASCO 0 and 3; n=1728; P<0,001); subdivision of cryptogenic strokes revealed a PFO in 24% of 978 ASCO 3 patients (n.s. versus ASCO 1 and 2) and a higher prevalence of 36% in 750 ASCO 0 cases (P<0.001 versus ASCO 3 and versus ASCO 1 and 2). PFO was more commonly observed in ASCO 0- (n=271) than in ASCO 0+ patients (n=479; 48 versus 29%; P<0.001). There was no PFO-associated magnetic resonance imaging lesion pattern.Cryptogenic stroke patients demonstrate a heterogeneous PFO prevalence. Even in case of less conclusive diseases like nonstenotic arteriosclerosis, patients should preferentially be considered to have a non-PFO-mediated stroke.URL: http://www.clinicaltrials.gov.
