Highlights ■ We validated the UHPLC/UV method for accurate busulfan quantification in plasma. ■ Inaccuracy and imprecision were below 15%, ensuring reliable therapeutic drug monitoring results. ■ This enables effective pharmacokinetic studies with rapid turnaround times in patient samples. ABSTRACT Objective: This study aimed to validate a sensitive, accurate, and precise bioanalytical ultrahigh- performance liquid chromatography coupled with ultraviolet (UHPLC/UV) method for the determination of busulfan in human plasma using 1,6-bis-(methanesulfonyloxy) hexane as an internal standard for therapeutic drug monitoring.

OBJECTIVE: To correlate the Apgar score, and neonatal mortality and its causes at a hospital located in the southern area of São Paulo City. METHODS: A retrospective study performed by analysis of medical charts (n=7,094) of all live newborns during the period of 2005 to 2009, with data up to 28 days of life in reference to weight, Apgar score, survival and cause of mortality. Cases were analyzed by the X² test (p < 0.05). RESULTS: In 7,094 births, there [...]
