Extremes of dysglycaemia as well as glycaemic variability are associated with excess mortality in critically ill patients. Glycaemic variability is an increasingly important measure of glucose control in the intensive care unit (ICU) due to this association; however, there is limited data pertaining to the relationship between exogenous glucose from nutrition and glycaemic variability and clinical outcomes. The primary aim of this study was to determine if glycaemic variability is associated with an increase in mortality. Secondary objectives were to investigate any factors affecting glycaemic variability, and to characterise the role nutrition, particularly carbohydrate, plays as a contributing factor to glycaemic variability and other clinical outcomes (duration of ventilation and ICU length of stay). ⋯ This study confirms that GV was associated with excess mortality. Furthermore, administration of increasing doses of insulin was associated with increased GV. Increased carbohydrate intake was associated with an increased insulin requirement, as well as increased duration of mechanical ventilation and ICU length of stay. These findings provide important context for further prospective trials investigating the effect of carbohydrate provision in mechanically ventilated critically ill patients requiring artificial nutritional support.

Teduglutide, a glucagon-like peptide 2 (GLP-2) analog, is an approved medication specific for short bowel syndrome patients with chronic intestinal failure (SBS-IF). Due to its intestinotrophic properties, it improves intestinal absorption of fluids and nutrients, which was shown to reduce the need for parenteral support in clinical trials. The present report aims to describe the experience of teduglutide's effects in routine medical care with focus on clinical and nutritional effects. ⋯ Teduglutide can be applied to anatomically and clinically heterogeneous SBS-IF patients and results in an adaptive response with variable time and effect range in routine medical care. Teduglutide-induced functional and structural changes bring on a gradual reduction of parenteral support at no cost to body composition and suggest an improved intestinal function with compensatory effect on nutritional status.

Resting energy expenditure (REE) formulas for healthy people (HP) are used to calculate REE (cREE) in amyotrophic lateral sclerosis (ALS) patients. In 50-60% of ALS cases an increase of measured REE (mREE) in indirect calometry (IC) compared to cREE is found. The aims here were (i) to assess the accuracy of cREE assessed using 11 formulas as compared to mREE and (ii) to create (if necessary) a specific cREE formula for ALS patients. ⋯ REE formulas for HP underestimate REE in ALS patients compared to mREE. Our new ALS-specific formula produced better results than formulas for HP. This formula can be used to estimate REE in ALS patients if IC is not accessible.

Hip fractures are strongly associated with mortality in the elderly. Studies investigating predisposing factors have suggested a negative impact of poor nutritional, cognitive and functional status on patient survival, however their independent prognostic impact as well as their interactions remain undefined. This study aimed to determine whether poor nutritional status independently predicts 1 year post-fracture mortality after adjusting for cognitive and functional status and for other clinically relevant covariates. ⋯ In hip fracture elderly patients, poor nutritional status strongly predicts 1 year mortality, independently of demographic, functional, cognitive and clinical risk factors. The negative prognostic impact of functional and cognitive impairment on mortality is mediated by their association with poor nutritional status.

To update the European Association for the Study of Diabetes (EASD) clinical practice guidelines for nutrition therapy, we conducted a systematic review and meta-analysis of randomized controlled trials to summarize the evidence for the effect of vegetarian dietary patterns on glycemic control and other established cardiometabolic risk factors in individuals with diabetes. ⋯ NCT02600377.
