The Parkinson Study Group SURE-PD Investigators determine the safety, tolerability, and urate-elevating capability of the urate precursor inosine in early Parkinson disease and assess its suitability and potential design features for a disease-modification trial.

In a prospective cohort study at 2 university-based hospitals between 2003 and 2005, Lima and coauthors investigate the outcomes of patients who had an acute ischemic stroke attributable to an anterior circulation proximal intracranial arterial occlusion.

Brouwers and colleagues develop a 9-point prediction score for hematoma expansion in patients with primary intracerebral hemorrhage. They perform a prospective cohort study at 2 urban academic medical centers among patients with available baseline and follow-up computed tomography. The prediction score was derived based on the regression estimates and was subsequently tested in an independent validation cohort.
