The Chilean socio-ethno-genomic cline.

Studies of the current Chilean population performed using classical genetic markers have established that the Chilean population originated primarily from the admixture of European people, particularly Spaniards, and Amerindians. A socioeconomic-ethno-genetic cline was established soon after the conquest. Spaniards born in Spain or Chile occupied the highest Socioeconomic Strata, while Amerindians belonged to the lowest.

Management of postoperative pain in Spain: a nationwide survey of practice.

Background: Although the need for structured assessment and management of acute postoperative pain has been recognized, practices and responsibilities vary between and within hospitals and countries.

Methods: Members of the Spanish Pain Society and APS/APMP heads were asked to respond to a survey.
