Review Meta Analysis Comparative Study
Comparison of the sex-specific associations between systolic blood pressure and the risk of cardiovascular disease: a systematic review and meta-analysis of 124 cohort studies, including 1.2 million individuals.
Conflicting results have been reported on whether the association between increments in systolic blood pressure (SBP) and cardiovascular disease differs between men and women. We performed a systematic review with meta-analysis to compare reliably sex-specific associations between SBP and cardiovascular risk. ⋯ Elevated levels of SBP are a major risk factor for stroke and ischemic heart diseases in both women and men. This study unequivocally demonstrates the broadly similar impact of SBP increments on cardiovascular outcomes in both sexes.

Review Historical Article
Review, historical context, and clarifications of the NINDS rt-PA stroke trials exclusion criteria: Part 1: rapidly improving stroke symptoms.
Since Food and Drug Administration approval of intravenous tissue-type plasminogen activator (tPA) for treatment of acute ischemic stroke in 1996, it has become clear that several criteria used for exclusion from therapy were not based on actual data or operationally defined for use in clinical practice. All eligibility criteria from the National Institute of Neurological Disorders and Stroke (NINDS) recombinant tPA Stroke Study were adopted within the alteplase package insert as contraindications/warnings. Many clinicians have expressed the need for clarification and better definition of these treatment criteria. ⋯ A structured framework and quantitative approach toward defining RISS emerged through expert opinion and consensus. The term, RISS, should be reserved for those who improve to a mild deficit, specifically one which is perceived to be nondisabling. This is recommended to guide decision making on intravenous tPA eligibility going forward, including the design of future studies. An additional study of patients with rapid improvement to nonmild deficits is not justified because these patients should be treated.
