BRAIN study: it is hard to draw a conclusion

Is it time to draw such a conclusion concerning the use of washed donor blood during paediatric cardiopulmonary bypass?

our study was exclusively the comparison of rightand left-sided unilateral cerebral perfusion (UCP) for efficiency of cerebral protection rather than the suitability of a particular carotid artery for arterial return. The assessment of pressure in the left radial artery is of utmost importance in UCP, regardless if rightor leftsided perfusion is performed, because it reveals the efficiency of c...

Is It “Fractured” or “Broken”? A Patient Survey Study to Assess Injury Comprehension after Orthopedic Trauma

Given the commonality of this frequently posed question, it may beimportant for providers to assess patients’ level of understanding in order to provide optimal care.

How Hard Is It to Take a Snapshot?

The snapshot object is an important and well-studied primitive in distributed computing. This paper will present some implementations of snapshots from registers, in both asycnhronous and synchronous systems, and discuss known lower bounds on the time and space complexity of this problem.
