Associations between Late Lactate Clearance and Clinical Outcomes in Adults with Hyperlactataemia in the Setting of Diabetic Ketoacidosis.

: This study aimed to determine the associations between lactate clearance in hyperlactataemic patients with diabetic ketoacidosis (DKA) and intensive care unit (ICU), hospital length of stay (LOS), and case-fatality. : A retrospective, multicentre, cohort study of adult patients admitted to ICU with hyperlactataemia and a primary diagnosis of DKA from twelve sites in Queensland, Australia was conducted utilising pre-existing datasets that were linked for research purposes. The patients were divided into early and late lactate clearance groups; the early lactate clearance group included patients whose lactate returned to <2.

Nutrition support, carbohydrate feeding and insulin sensitivity in the critically ill patient: a complex relationship.

Purpose Of Review: This review aims to summarize recent studies that highlight the complex relationship between nutrition, carbohydrate, insulin provision and glycaemic control in the critically ill patient population.

Recent Findings: Results of observational studies concur to support early hypoglycaemia and persisting hyperglycaemia as life-threatening events. In contrast, interventional studies indicate that early macronutrient restriction appears to reduce the benefits related to insulin therapy.

Association between elevated lactate and clinical outcomes in adults with diabetic ketoacidosis.

Purpose: To assess the occurrence of hyperlactatemia among patients admitted to the intensive care unit (ICU) with diabetic ketoacidosis (DKA), and effect on in-hospital mortality.

Materials And Methods: A retrospective, multicentre, cohort study of adult patients admitted to ICU with a primary diagnosis of DKA in Australia and New Zealand, utilising a pre-existing dataset. The primary exposure variable was lactate, dichotomised into normolactatemia (lactate <2.

Nutritional therapy in critically ill patients with diabetes.

Purpose Of Review: There has been a significant increase in nutrition therapy related studies within the critical care cohort in recent years. Management of patients with both diabetes and stress hyperglycaemia through targeted nutrition interventions is no exception. The aim of this review is to outline current available diabetes specific nutrition formula, its impact on gastric emptying and subsequently glycaemic control as well as explore recent literature on the efficacy of utilizing nutrition support to optimize glycaemic control in critically ill patients.

The impact of a modified carbohydrate formula, and its constituents, on glycaemic control and inflammatory markers: A nested mechanistic sub-study.

Background: Hyperglycaemia occurs frequently in the critically ill. Dietary intake of advanced glycation end-products (AGEs), specifically Nε-(carboxymethyl)lysine (CML), may exacerbate hyperglycaemia through perturbation of insulin sensitivity. The present study aimed to determine whether the use of nutritional formulae, with varying AGE loads, affects the amount of insulin administered and inflammation.

Nutrition management for critically and acutely unwell hospitalised patients with coronavirus disease 2019 (COVID-19) in Australia and New Zealand.

Coronavirus disease 2019 (COVID-19) results from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The clinical features and subsequent medical treatment, combined with the impact of a global pandemic, require specific nutritional therapy in hospitalised adults. This document aims to provide Australian and New Zealand clinicians with guidance on managing critically and acutely unwell adult patients hospitalised with COVID-19.

The effect of a low carbohydrate formula on glycaemia in critically ill enterally-fed adult patients with hyperglycaemia: A blinded randomised feasibility trial.

Background: Enteral nutrition is a source of carbohydrate that may exacerbate hyperglycaemia. Its treatment, insulin, potentially exacerbates glycaemic variability.

Methods: This was a prospective, parallel group, blinded, randomised feasibility trial.

Glycaemic variability and its association with enteral and parenteral nutrition in critically ill ventilated patients.

Background & Aims: 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.

Diabetes-Specific Formulae Versus Standard Formulae as Enteral Nutrition to Treat Hyperglycemia in Critically Ill Patients: Protocol for a Randomized Controlled Feasibility Trial.

Background: During critical illness, hyperglycemia is prevalent and is associated with adverse outcomes. While treating hyperglycemia with insulin reduces morbidity and mortality, it increases glycemic variability and hypoglycemia risk, both of which have been associated with an increase in mortality. Therefore, other interventions which improve glycemic control, without these complications should be explored.
