News-medical: October 26, 2012 A clinical trial indicates that using an investigational medical device to close a PFO, or “hole in the heart,” may be superior to medical management alone in the prevention of a repeated stroke. Results of the RESPECT trial were presented today at the 24th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by […]

Stroke AHA Journals: November 1, 2012 Recent analysis of National Get-with-the-Guidelines data has shown that less than one third of all patients treated with intravenous tissue plasminogen activator (tPA) had door-to-needle times (DTN) within the ‘Golden Hour’ recommended by current guidelines. Accumulating evidence indicates that shorter DTN is associated with improved outcomes. In March 2011, […]

Wiley: OCT 23, 2012 The cluster-randomized controlled trial is a design increasingly used in prevention and health care evaluation studies and is highly relevant to stroke research. However, there are methodological issues that make it complex to implement. These are not always fully appreciated, with reviews continuing to reveal deficiencies. We searched PUBMED and CENTRAL databases […]

Stroke AHA Journals: October 23, 2012 With Recent Transient Ischemic Attack or Stroke Elevated concentrations of homocysteine are associated with cerebral small vessel disease (CSVD). B-vitamin supplementation with folate and vitamins B12and B6 reduces homocysteine concentrations. In a substudy of the VITAmins TO Prevent Stroke (VITATOPS) trial, we assessed the hypothesis that the addition of once-daily supplements […]

ScienceDaily (Oct. 16, 2012) — On average, new treatments perform better in clinical trials only slightly more often than existing treatments, according to a new systematic review published in The Cochrane Library. The fact that experimental treatments are not more effective may seem disappointing, but the authors of the review say their findings satisfy an important ethical […]

Neurology: October 17, 2012 Randomized controlled trials are required to determine the effectiveness and safety of medical therapies for clinical use. However, observational studies are used frequently to evaluate treatment effects in a number of situations, such as postmarketing safety evaluations of medications or in situations where clinical trials are not feasible.1 Unlike randomized controlled trials, where […]
