Validation of an ultra-high performance liquid chromatography/UV method to quantify busulfan in plasma: application to therapeutic drug monitoring
DOI: 10.31744/einstein_journal/2025AO0964
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.

Adequacy of nutritional status and dietary intake of adult and elderly patients with American Tegumentary Leishmaniasis
DOI: 10.31744/einstein_journal/2025AO0992
Highlights ■ Most patients had an inadequate intake of selenium, calcium, magnesium, and fiber. ■ Patients with mucosal had lower body weight, arm muscle circumference, and serum albumin and zinc intake. ■ Mucosal is associated with insufficient zinc intake, low body weight, and the depletion of serum albumin and transferrin. ■ Oropharyngeal lesions are associated with calorie malnutrition and serum protein depletion. ABSTRACT Objective: Patients with American Tegumentary Leishmaniasis often experience malnutrition, weight loss, and dehydration; however, their eating profile […]
