Randomized Controlled Trial
Effects of food on the pharmacokinetics of ponatinib in healthy subjects.
Ponatinib is a potent oral tyrosine kinase inhibitor with activity against BCR-ABL, the primary driver of chronic myeloid leukaemia and Philadelphia chromosome-positive acute lymphoblastic leukaemia. This single-centre, single-dose, randomized, open-label, three-period crossover study evaluated the pharmacokinetics and bioavailability of a single oral dose of ponatinib (45-mg tablet) under fasting conditions and following consumption of high- and low-fat meals by healthy subjects. ⋯ Food does not affect the single-dose pharmacokinetics of ponatinib. These data demonstrate that ponatinib may be administered with or without food.

Augmented renal clearance--an evolving risk factor to consider during the treatment with vancomycin.
Augmented renal clearance (ARC) is a new phenomenon in patients' pathophysiology without universally accepted aetiology and with various incidence rates most often described in critically ill patients in the Intensive Care Unit (ICU). The objective of this retrospective observational comparative study was to estimate the incidence rate of ARC in patients with different medical conditions employing steady state trough vancomycin serum concentrations (VSCss) for analysis. ⋯ ARC cases lead to the doubled risk of subtherapeutic VSC, and this phenomenon is a significant event in patients in any hospital department. Investigation of medical patients' status relevant to this phenomenon needs to be continued.

Probiotic therapy has been shown to reduce morbidity and mortality of necrotizing enterocolitis (NEC) in premature infants in several international studies using various probiotic agents. The purpose of this study(*) is to describe our experience of using probiotic therapy in preventing NEC in infants with very low birth weight (VLBW) in a neonatal intensive care unit (NICU) and to evaluate whether our records provide evidence of effectiveness for probiotic therapy. ⋯ Our findings suggest that probiotics are safe in NEC prevention in VLBW infants. We had no cases of infection related to the strains of bacteria used in our product. With the low incidence of NEC (2·8%) and NEC scare (2·8%) in our cohort, we do not have enough power to detect any change in outcome, particularly as our study was observational. However, it is hoped that our data give useful information for others on probiotic prophylactic therapy in the routine clinical management of VLBW infants.
