Percutaneous cholecystostomy… why, when, what next? A systematic review of past decade

Adaptive query processing: Why, How, When, and What Next?

Adaptive query processing has been the subject of a great deal of recent work, particularly in emerging data management environments such as data integration and data streams. We provide an overview of the work in this area, identifying its common themes, laying out the space of query plans, and discussing open research problems. We discuss why adaptive query processing is needed, how it is bei...

The Why, Who, What, How, and When of Patient Engagement in Healthcare Organizations: A Response to Recent Commentaries

Supersymmetry: what? why? when?

This article is a colloquium-level review of the idea of supersymmetry and why so many physicists expect it to soon be a major discovery in particle physics. Supersymmetry is the hypothesis, for which there is indirect evidence, that the underlying laws of nature are symmetric between matter particles (fermions) such as electrons and quarks, and force particles (bosons) such as photons and gluons.

Cholecystectomy vs. percutaneous cholecystostomy for the management of critically ill patients with acute cholecystitis: a protocol for a systematic review

BACKGROUND Acute cholecystitis is a common diagnosis. However, the heterogeneity of presentation makes it difficult to standardize management. Although surgery is the mainstay of treatment, critically ill patients have been managed via percutaneous cholecystostomy. However, the role of percutaneous cholecystostomy in the management of such patients has not been clearly established. This systema...
