Malnutrition in older adults results in significant personal, social, and economic burden. To combat this complex, multifactorial issue, evidence-based knowledge is needed on the modifiable determinants of malnutrition. Systematic reviews of prospective studies are lacking in this area; therefore, the aim of this systematic review was to investigate the modifiable determinants of malnutrition in older adults. ⋯ There are multiple potentially modifiable determinants of malnutrition however strong robust evidence is lacking for the majority of determinants. Better prospective cohort studies are required. With an increasingly ageing population, targeting modifiable factors will be crucial to the effective treatment and prevention of malnutrition.

Central venous access device (CVAD)-related complications, such as central-line associated bloodstream infections (CLABSIs), CVAD-related venous thromboses (CRVTs) and -occlusions frequently occur in home parenteral nutrition (HPN) patients. A preventive strategy to decrease the incidence of CLABSIs is the use of CVAD lock solutions, such as 2% taurolidine. The aim of this study was to evaluate long-term clinical outcomes of our HPN cohort while using taurolidine as lock solution. In addition, we explored risk factors associated with CVAD-related complications. ⋯ Complication rates remained low in the long-term, and use of taurolidine was generally safe. The identified risk factors may help to create new strategies to further prevent CVAD-related complications and improve HPN care in the future.

Randomized Controlled Trial
Supplemental parenteral nutrition improves immunity with unchanged carbohydrate and protein metabolism in critically ill patients: The SPN2 randomized tracer study.
Individualized supplemental parenteral nutrition (SPN) providing measured energy expenditure from day 4 reduced infectious complications in a previous study including 305 intensive care (ICU) patients. The study aimed at investigating the metabolic, and immune responses underlying the clinical response of the previous trial. ⋯ NCT02022813 at https://clinicaltrials.gov/.

Randomized Controlled Trial
A randomized controlled study of preoperative oral carbohydrate loading versus fasting in patients undergoing elective craniotomy.
The aim of this study was to evaluate the effect of preoperative oral carbohydrate loading versus fasting on the outcomes of patients undergoing elective craniotomy. ⋯ Oral carbohydrate loading given 2 h before surgery in patients undergoing elective craniotomy seems to improve glucose homeostasis, handgrip strength and pulmonary function as well as decrease LOS without increasing the risk of postoperative complications. Routine use of preoperative oral carbohydrate loading could be suggested in clinical settings, though further evaluation of its safety and efficacy is warranted.

High concentrations of trace elements (TE), in particular zinc and selenium, along with carnitine, are often added to parenteral admixtures in paediatric patients on long-term Parenteral Nutrition (PN). We aim to evaluate whether lipid droplet diameters of these admixtures maintain the recommended range of 0.4-1.0 μm. ⋯ Carnitine and high concentrations of trace elements do not affect PN admixtures stability and can be safely infused in long-term home-PN paediatric patients and prematures. Only high calcium concentrations in compresence with fish oil based lipid emulsions seem to change PN stability.
