[Variability in walk test conditions in pulmonary rehabilitation programs in Latin America and on the Iberian peninsula].

Objective: 1) To determine the frequency of use of the 6-minute walk test in pulmonary rehabilitation programs in Latin America and on the Iberian Peninsula; 2) to identify how the test is performed and possible variations from center to center.

Materials And Methods: A questionnaire was sent to 55 pulmonary rehabilitation centers in Latin America, Portugal, and Spain.

Results: Forty-nine (89.

The multipurpose surveillance-oriented medical record: a tool for quality of care management.

Medical records were oriented towards quality of care surveillance by adding dedicated sections to the progress notes in which to list admission problems, medical interventions and adverse events (AEs). Two types of simple code were used: indication codes, which identify the indication for any given medical intervention; and attribution codes, which indicate the causes of any AE. During the first 6 months (302 patients), 24 AEs were attributed to drugs, three to procedures, and 42 were unexplained.

Immobilization of endo-polygalacturonase from Aspergillus niger on various types of macromolecular supports.

Endo-polygalacturonase (endo-PG) was immobilized on a wide range of natural and synthetic macromolecular supports and their modified derivatives representing many chemical classes, including esters, amides, phenols, alkyl- and arylamines, and carboxyl derivatives. The immobilization entailed methods of adsorption alone as well as covalent bond formation using glutaraldehyde or carbodiimide or via the diazo-coupling reaction. The most promising system proved to be immobilization on trimalehylchitosan (TMC) via adsorption followed by treatment with glutaraldehyde (GA).
