Effects of Kangaroo Care on the development of oral skills and achievement of exclusive oral feeding in preterm infants.

Purpose: analyze the effects of hospitalization in the Kangaroo Neonatal Intermediate Care Unit (UCINCa), the second stage of the Kangaroo Care (KC), on the development of oral feeding skills in preterm neonates.

Methods: an analytical observational study of the prospective longitudinal type, carried out in a public hospital in Southern Brazil, where infants were accompanied until hospital discharge. The sample consisted of 20 preterm neonates hospitalized at the UCINCa and 26 preterm neonates at the Conventional Neonatal Intermediate Care Unit (UCINCo), that were periodically evaluated through the levels of oral skill, in a bottle, according to the criteria of proficiency and milk transfer rate.

Vancomycin and creatinine determination in dried blood spots: Analytical validation and clinical assessment.

This study aims to develop a liquid chromatography tandem-mass spectrometry (LC-MS/MS) method for vancomycin and creatinine measurement in dried blood spots (DBS) and to evaluate its clinical application. The analytes were extracted from DBS and analyzed by LC-MS/MS. Vancomycin and creatinine DBS and plasma concentrations were compared in 54 and 35 samples, respectively, from 29 patients.
