Commodities are raw materials intended for use or consumption. There are three main commodity classifications: Agriculture commodities (often referred to as soft commodities), energy commodities, and metal commodities (referred to as hard commodities). The most commonly traded commodities are crude oil, gold, silver, and copper. Commodity markets can include physical delivery, referred to as a spot contract. Most trades, however, are carried out through derivative trading using futures, forwards, CFD's, and options.

There is significant controversy surrounding goal-directed therapy (EGDT) in the management of severe sepsis and septic shock.owever, the investigators noted a trend toward improved outcome in patients with severe sepsis who received 4% albumin rather than normal saline. The data are inconclusive, especially with regard to the initial resuscitation phase for septic shock in the ED; therefore, crystalloid fluid resuscitation is recommended.
