Assessment of trace elements in critically ill patients with systemic inflammatory response syndrome: A systematic review.

Background: Zinc (Zn), copper (Cu), and selenium (Se) are involved in immune and antioxidant defense. Their role in systemic inflammatory response syndrome (SIRS) treatment and outcomes remains unclear. This systematic review aimed to describe trace element concentrations in different types of biological samples and their relationship with morbidity and mortality in patients with SIRS.

Nutritional screening tool for critically ill children: a systematic review.

Context: Nutritional screening tools (NSTs) are used to identify patients who are at risk of nutritional status (NS) deterioration and associated clinical outcomes. Several NSTs have been developed for hospitalized children; however, none of these were specifically developed for Pediatric Intensive Care Unit (PICU) patients.

Objective: A systematic review of studies describing the development, application, and validation of NSTs in hospitalized children was conducted to critically appraise their role in PICU patients.

Vitamin C decreases reduced glutathione in chronic haemodialysis patients: a pilot, randomised, double-blind trial.

Purpose: Whey protein has antioxidant properties through its amino acid cysteine, which enhances the biosynthesis of glutathione, the most abundant antioxidant non-protein in mammalians. Glutathione influences vitamin C recycling and increases its protective effect on oxidative stress (OS). The aim of this study was to analyse the effect of whey protein and vitamin C supplementation on OS biomarkers in chronic haemodialysis (HD) patients.

Admission factors associated with nutritional status deterioration and prolonged pediatric intensive care unit stay in critically ill children: PICU-ScREEN multicenter study.

Background: Early identification of patients in the pediatric intensive care unit (PICU) at risk of nutritional status (NS) deterioration and poor outcomes is desirable. We aimed to identify factors associated with NS deterioration and prolonged PICU stay.

Methods: Prospective cohort study in eight Brazilian PICUs with children <18 years with a PICU stay >72h.

Apple intake improves antioxidant parameters in hemodialysis patients without affecting serum potassium levels.

Oxidative stress (OS) is associated with increased morbidity and mortality in hemodialysis (HD) patients, and the consumption of fruits seems to improve OS due to their antioxidant properties. Therefore, we hypothesized that Fuji apple intake improves OS markers in HD patients due to its polyphenolic compounds without increasing serum potassium levels. This trial was a 1-group, pre- and posttest comparison between 16 patients who had been on hemodialysis for at least 3 months without any acute illness or hyperkalemia.
