Concise review : Developing best-practice models for the therapeutic use of extracellular vesicles

Abstract: Growing interest in extracellular vesicles (EVs, including exosomes and microvesicles) as therapeutic entities, particularly in stem cell-related approaches, has underlined the need for standardization and coordination of development efforts. Members of the International Society for Extracellular Vesicles and the Society for Clinical Research and Translation of Extracellular Vesicles Singapore convened a Workshop on this topic to discuss the opportunities and challenges associated with development of EV-based therapeutics at the preclinical and clinical levels. This review outlines topic-specific action items that, if addressed, will enhance the development of best-practice models for EV therapies. Stem Cells Translational Medicine 2017;6:1730-1739.

Sarcoidosis in America. Analysis Based on Health Care Use.

Abstract: Rationale: There have been no recent comprehensive studies of the epidemiology of sarcoidosis in the United States. Changes in health care use have made available access to data on large numbers of patients with sarcoidosis.Objectives: To use a U.S. national health care database to gather data on patients with sarcoidosis identified over a 3-year period who were 18 years of age and older, and to determine health care costs for these patients.Methods: The Optum health care database was queried for a 3-year period (2010–2013). This database includes approximately 15% of U.S. residents. The incidence rate of sarcoidosis was calculated for new cases identified in each year. Calculation of prevalence was based on any patient with sarcoidosis seen during the year. Incidence and prevalence rates are reported per 100,000 patients.Measurements and Main Results: A total of 29,372 adult patients with sarcoidosis were identified. Of these, 14,700 (55%) were over 55 years of age at the time of diagnosis. The incidence...

NXY-059 for the treatment of acute stroke: pooled analysis of the SAINT I and II Trials

Abstract: Background and Purpose— In animal models of acute ischemic stroke (AIS), the free radical–trapping agent NXY-059 showed promise as a neuroprotectant. SAINT I and II were randomized, placebo-controlled, double-blind trials to investigate the efficacy of NXY-059 in patients with AIS. Methods— Patients with AIS received an infusion of intravenous NXY-059 or placebo within 6 hours from the onset of stroke symptoms. A pooled individual patient analysis was prespecified to assess the overall efficacy and to examine subgroups. The primary end point was the distribution of disability scores measured on the modified Rankin scale (mRS) at 90 days. Neurologic and activities of daily living scores were investigated as secondary end points. We also evaluated whether treatment with NXY-059 would reduce alteplase-related intracranial hemorrhages. Finally, we evaluated possible predictors of good or poor outcome. Results— An intent-to-treat efficacy analysis was based on 5028 patients. Baseline parameters and prognostic ...
