La semiótica de Lotman como teoría del conocimiento/ Lotman Semiotics Like a Knowledge Theory

Mosquera, Alexander

Resumen en español Iuri Mijáilovich Lotman (1922-1993) fue un investigador de la Universidad de Tartu (Estonia) de reconocida trayectoria internacional, cuyos aportes en el ámbito de la Semiótica de la Cultura trascendieron las fronteras de la entonces Unión Soviética, aún a pesar de las dificultades y censuras impuestas por el gobierno comunista a la difusión de su obra. Según Cáceres (en Lotman, 1996), dicha obra abarcó toda una diversidad de problemas más allá de la teoría s (mas) emiótica, para adentrarse en la mitología, el cine, la historia de la cultura, la estética, el teatro, la literatura, entre otros. La presente reflexión teórica, a partir del análisis de La semiosfera II. Semiótica de la cultura, del texto, de la conducta y del espacio (1998), pretende agregar valor a los aportes de Lotman, al escudriñar sus planteamientos y asomarlos como base para construir una teoría del conocimiento. Resumen en inglés Iuri Mijailovich Lotman (1922-1993) was an investigator of Tartu University (Estonia) with a recognized international trajectory, whose contributions in the field of the Semiotics of Culture extended the borders of the then so called Soviet Union, in spite of the difficulties and censorships imposed by the communist government to the diffusion of their work. According to Caceres Sanchez (in Lotman, 1996), this work included a whole diversity of problems beyond the Semioti (mas) cs theory, to enter itself in mythology, cinema, history of culture, aesthetic one, theater, Literature, among others. The present theoretical reflection tries to add a value more to the Lotman contributions, when examining his text La semiosfera II. Semiótica de la cultura, del texto, de la conducta y del espacio (1998) and showing them as the bases to construct a knowledge theory.

La resistencia a múltiples fármacos: una amenaza para el control de la tuberculosis/ Multiple drug resistance: a threat for tuberculosis control

Cardoso, Ernesto Montoro

Resumen en inglés Drug-resistant tuberculosis (TB) was reported soon after the introduction of streptomycin, although it did not receive major attention until recently. It was not considered a major issue in the industrialized world until outbreaks of multidrug-resistant TB (MDR-TB) were reported among HIV infected people. Administration of standard short-course chemotherapy (SSCC) with first-line drugs under directly observed therapy (DOT) is the cornerstone of modern TB control. Unfortun (mas) ately, data available on the treatment outcome of MDR-TB cases under routine programmatic conditions suggest that patients with MDR-TB respond poorly to SSCC with first-line drugs. Since 1994, the World Health Organization and the International Union Against Tuberculosis and Lung Disease (IUATLD) have conducted anti-TB drug resistance surveys through a network of subregional laboratories and researchers. Drug resistance was present in almost all settings surveyed, and prevalence varied widely across regions. High prevalence of MDR-TB is widespread in the Russian Federation and areas of the former Soviet Union (Estonia, Kazakhstan, Latvia, and Lithuania) as well as Israel, Liaoning and Henan Provinces in China, and Ecuador. The Global Project has surveyed areas representing over one third of notified TB cases. However, enormous gaps still exist in the most crucial areas. The most effective strategy to prevent the emergence of drug resistance is through implementation of the directly observed treatment short (DOTS) strategy. Effective implementation of the DOTS strategy saves lives through decreased TB transmission, decreased risk of emergence of drug- resistance, and decreased risk for individual TB patients of treatment failure, TB relapse, and death. The World Bank recognizes the DOTS strategy as one of the most cost-effective health interventions, and recommends that effective TB treatment be a part of the essential clinical services package available in primary health care settings. Governments are responsible for ensuring the provision of effective TB control through the DOTS strategy. WHO and its international partners have formed the DOTS-Plus Working Group, which is attempting to determine the best possible strategy to manage MDR-TB. One of the goals of DOTS-Plus is to increase access to expensive second-line anti-TB drugs for WHO-approved TB control programmes in low- and middle-income countries.
