Burnout and patient safety: A discriminant analysis of paediatric nurses by low to high managerial support.

AIM: To explore how levels of managerial support discriminate paediatric nurses' burnout, quality of life, intent to leave and adverse patient events. DESIGN: A quantitative correlational study. METHODS: A total of 225 paediatric nurses were selected from nine major hospitals across Jordan. The main measures used were the Copenhagen Burnout Inventory and the brief version of World Health Organization-Quality of Life Instrument. The study methods were compliant with the STROBE checklist. RESULTS: Nurse manager support was negatively associated with adverse patient events, work-related burnout, client-related burnout, and intent to leave; and positively with physical and psychological quality of life. Frequency of nosocomial infections characterized low manager support, whereas medication errors described high support. Greater nurse manager support decreased the likelihood of adverse patient outcomes.

In vitro formation of selegiline-N-oxide as a metabolite of selegiline in human, hamster, mouse, rat, guinea-pig, rabbit and dog.

It is well established in the litrature, that selegiline is metabolised to its N-dealkylated metabolites, N-desmethylselegiline, methamphetamine and amphetamine. However, most studies on selegiline metabolism did not characterize the species differences in the formation of the metabolites. Therefore, in this study, we investigated the in vitro metabolism of selegiline in liver microsomes of different species. In addition, to the previously well-characterized metabolites, selegiline-N-oxide (selegiline-NO) was found to be formed as a metabolite of selegiline in rat liver microsomal preparation. The results of experiments with liver microsomes from other species indicated species differences in the rate and extent of formation of selegiline-NO. The dog and hamster liver microsomal preparations were the most active in terms of selegiline-NO production, whereas little selegiline was metabolized to its N-oxide in human liver microsomes. When selegiline-NO was incubated with rat liver microsomes, no metabolism occurred. When a short incubation time was applied in selegiline expriments no increase in the amount of selegiline-NO was detected. Accordingly, it was clear that selegiline was not metabolized to the N-dealkylated or N,N-bis-dealkylated compounds via selegiline-NO. Studies with different isoenzyme inhibitors indicated that the formation of selegiline-NO might be catalyzed at least partly by cytochrome P450 (CYP) 2D6 and CYP3A4. With the exception of hamster microsomes in the microsomal preparations in vitro, the formation of the R,S-stereoisomer of selegiline-NO was preferred.
