Background: Storage of whole blood (WB) for less than 24 hours at ambient temperature is permitted in Europe, but data directly comparing storage with and without active cooling are lacking, which was investigated and compared to current standard methods.
Study Design And Methods: WB was stored in one of four different ways for 24 hours after donation before processing on Day 1 to red cell concentrates (RCCs) in saline-adenine-glucose-mannitol and fresh-frozen plasma (FFP; n = 20 each): 1) at 22 degrees C in plastic trays, 2) in cooling devices (Compocool II, NPBI), 3) at 4 degrees C, or 4) processed from WB without storage less than 8 hours from donation (Day 0).
Results: 2,3-Diphosphoglycerate (2,3-DPG) in RCCs were lower after ambient storage compared with those processed on Day 0 or after 4 degrees C storage.

A meta-analysis has been performed including nineteen double blind, placebo controlled studies with piracetam in patients suffering from dementia or cognitive impairment in the elderly. These studies had as common outcome measure a clinical global impression of change, a measure of clinically meaningful improvement. The meta-analysis of this global outcome followed the methodology set forward by the Cochrane Collaboration.

In various studies, 751 children have completed treatment in controlled double-blind trials using standardised tests of reading as outcome measures. Quantitative and qualitative review suggests that the findings are best interpreted as showing a statistical superiority of piracetam over placebo.

Twenty-seven children (or smaller subgroups depending upon task difficulty and subject ability) with subaverage IQs took part in a double-blind, placebo-controlled, cross-over study of methylphenidate (0.4 mg/kg/day) and thioridazine (1.75 mg/kg/day).
