The influences of the L-asparagine and glycerol initial concentrations in Sauton medium on the productivities of biomass and colony forming units were studied. The submerged batch cultivations of Mycobacterium bovis were carried out in a 20 L bioreactor. The L-asparagine and glycerol initial concentrations of 4.54 g/L and 25 mL/L, respectively, corresponded to the best biomass productivity, namely 2.5 g/L.day. On the other hand, the concentrations of 2.27 g/L and 25 mL/L, respectively, led to the highest productivity in terms of colony forming units, namely 2.7•10 6 colonies/mg.day. In addition, by means of the relative consumption analysis of L-asparagine and glycerol (50 and 26% respectively), it was concluded that the concentrations of such components could be reduced, with respect to the original Sauton medium composition, aiming the obtainment of an optimal BCG vaccine production in the bioreactor.
The objective of the study was to evaluate the use of human albumin in a Brazilian university hospital, in compliance with the institutional protocol and other clinical guidelines, taking into account the therapeutic indications and the dosage regimens. Data was obtained from the pharmacy dispensing records of human albumin, the requests for use it and, when available, the patient's records between January and October 2017. After evaluation the therapeutic indications and the dosage regimens were classified as "appropriate" and "inappropriate". The analysis of 98 requests showed that, when compared to the institutional protocol, 54 (55.1%) requests had an inappropriate therapeutic indication. However, when a comparison was made between 25 medical records (54 requests) and other clinical guidelines, it was observed that the therapeutic indication had none classified as inappropriate. In addition, 16 (29.7%) requests were considered inappropriate in relation to dosage regimens. From these results, it was possible to conclude that although the use of human albumin in the hospital was associated to a clinical protocol, it was outdated. Thus, it is possible to affirm that not only the adoption of a clinical protocol, but its periodical updating is an important strategy to promote the rational use of drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
