The aim of mechanical ventilation is to substitute physiological respiratory function. The boom of mechanical ventilation came during the XVIII century with the development of Reanimation Societies in Europe, who promoted the use of positive pressure ventilation modes. ⋯ Positive pressure ventilation was relegated to operating rooms until 1952, when it was imposed over negative pressure ventilation during the Copenhagen polio epidemic. Björn Ibsen contributed significantly to this change of ventilation paradigm, which led to the latest ventilation strategies and the development of the actual intensive care units.

[Evaluation of HIV epidemic in Chile. A statement of the Chilean Academy of Medicine].
The Chilean Academy of Medicine convened a commission to evaluate the status of HIV epidemic and the national response to it, regarding its achievements, gaps and challenges, aiming to recommend actions to optimize assessment quality and national response. This publication summarizes the agreed upon opinion of its members. The epidemic is overwhelmingly sexually transmitted, predominant in homo/bisexual men. ⋯ Despite these clear achievements, insufficient, occasionally inadequate public policies and certain rigid regulations thwart optimal effectivity and efficiency of the programs, contributing to the slow and incomplete compliance with international commitments. Shortcomings worth highlighting are: suboptimal educational and preventive programs directed to youngsters, vulnerable and general population; persistent underdiagnosis of infected population; cumbersome requirements to request and inform diagnostic tests, thus discouraging testing; excessive centralization and long latency of diagnosis confirmation and monitoring tests; incomplete epidemiologic analysis and public reporting of findings; non flexibility and slow updating of therapeutic guidelines; insufficient adaptation of care and drug delivery modalities to patients' needs; excessive administrative requirements at care centers and restrictive legislation for outcome and interventional clinical research. Recommendations to deal with these issues were proposed.
