TL;DR: This systematic review will summarise the evidence for the effectiveness of mobile technology interventions for improving health and health service outcomes (M-health) around the world and guide future work on intervention development and primary research in this field.

TL;DR: Caffeine may be an effective intervention for improving performance in shift workers however, there are no trials from which to assess its effect on injuries and there is no reason for healthy individuals who already use caffeine within recommended levels to improve their alertness to stop doing so.

TL;DR: Demand for albumin fell steeply after publication of the systematic review and there should be some concern that albumin may have been replaced by non-albumin colloids as there is no compelling evidence that these are superior and these products may also have important adverse effects.
