    Latin America Goes Electric: The Growing Social Challenges of Hydroelectric Development
    (IEEE, 2013) Varas Valenzuela, Pablo I.; TironiRodó, Manuel; Rudnick van de Wyngard, Hugh; Rodríguez, N.
    Hydroelectricity was, for many years, one of the main ways to meet the new electricity needs of Latin American countries. This is evidenced by the presence of some of the larger plants worldwide and the high hydroelectric participation in all electricity matrices (Figure 1). Faced with growing prospects for future economic development, an underlying concern is how to respond to the important and growing demands for electricity. In several countries, governments and electric companies have opted to continue with the construction of hydropower plants, especially large-scale ones, as the main means of meeting this challenge. However, major projects formulated in recent years have been put in check by various difficulties, some even stopped. Despite the different political, regulatory, and economic conditions that exist in Latin America, there are common elements in the difficulties faced by these projects. While in the past, large-scale hydroelectricity was the successful response to higher electricity consumption, societies have changed, and this technology faces new cultural, social, and political conditions.

    Primer aislado de Pseudomonas aeruginosa productora de Sao Paulo metalo-β-lactamasa (SPM-1) en un paciente chileno
    (2021) Wozniak, A.; Rodríguez, N.; Alcalde-Rico, M.; Castillo, C.; García, P.
    Las enzimas VIM, IMP, y NDM son carbapenemasas de tipo metalo-β-lactamasas (MBLs) que se encuentran ampliamente distribuidas en el mundo. La SPM-1 (Sao Paulo metalo-β-lactamasa) es una MBL que fue descrita en Pseudomonas aeruginosa en Sao Paulo (Brasil) en 2002. Comunicamos por primera vez la presencia de SPM-1 en Chile, en un aislado de P aeruginosa resistente a meropenem e imipenem, detectado en un cultivo rectal de vigilancia de carbapenemasas desde un paciente internado en nuestra institución. La secuencia del producto de la RPC fue 100% idéntica a la secuencia de SPM-1 reportada en Brasil. El paciente tenía antecedentes de una angioplastía realizada en Brasil en 2004-2005. Como consecuencia de este hallazgo, la detección de SPM mediante RPC será incorporada a la búsqueda de rutina de carbapenemasas en P aeruginosa.
