BackgroundResearch in animal models on cerebral metabolism after brain injury highlights the potential benefits of ketosis in reducing secondary brain injury, but studies in humans are lacking.AimThis study aimed to examine if a 6-week ketogenic diet intervention with added medium-chain triglycerides (MCT) was feasible in adult patients with acquired brain injury in the subacute phase, whether ketosis could be achieved and maintained, and to what extent serious adverse reactions, adverse reactions, serious adverse events, and adverse events occured.MethodsPatients ≥18 years of age diagnosed with subacute acquired brain injury and an expectation of hospitalisation ≥6 weeks were included in the intervention group. Patients not included in the intervention group were included in a standard care reference group. The intervention consisted of a ketogenic diet supplemented with MCT to obtain a plasma concentration of β-hydroxybutyrate (BHB) ≥0.5 mmol/L. Patients who were enterally fed were given KetoCal® 2.5:1 LQ MCT Multi Fiber (Nutricia A/S, Allerød, Denmark), supplemented with Liquigen® (Nutricia A/S, Allerød, Denmark). Patients consuming oral nutrition were given KetoCal® 2.5:1 LQ MCT Multi Fiber supplemented with Liquigen®, in addition to ketogenic meals.ResultsDuring a 13-week inclusion period, 12 of 13 eligible patients (92% [95% CI: 67% to 99%]) were included in the intervention group, and 17 of 18 excluded patients (94% [95% CI: 74% to 99%]) were included in the reference group. Eight patients (67%) completed the 6-week intervention. It took a median of 1 day to achieve ketosis from starting a 100% MCT ketogenic diet, and it was maintained for 97% of the intervention period after ketosis was obtained. There were no serious adverse reactions to the MCT ketogenic diet, and patients experienced adverse reactions not considered serious in 9.5% of days with the intervention. The MCT ketogenic diet was accepted by patients on all intervention days, and in the two patients transitioning from enteral feeding to oral intake, there were no complications related to transitioning.ConclusionIntervention with MCT ketogenic diet is feasible and tolerated for 6 weeks in hospitalised adult patients with subacute acquired brain injury. Randomised controlled trials are needed to assess the benefits and harms of the MCT ketogenic diet and the effect on patients’ recovery.Clinical trial registration:ClinicalTrials.gov, identifier [NCT04308577].

Objectives The measurement of fasting glucose is a common practice for lowering the risk of hyperglycemia before an oral glucose tolerance test (OGTT). In this study we analyze advantages and limitations of near-patient measurement of capillary fasting glucose with a portable glucometer or blood sampling and measurement of plasma glucose with laboratory instrumentation. Methods The final study population consisted of 241 subjects (mean age: 36 ± 8 years; 97.9 % pregnant women) referred to our local phlebotomy center for an OGTT. Fasting glucose was measured in capillary blood using a near-patient glucometer (glucometer-based strategy) and in plasma with laboratory instrumentation using the hexokinase reference assay (laboratory-based strategy). Results The mean turnaround time from sample collection to obtaining the glucose value was longer with the laboratory-based strategy (32 min 8 vs. 8 s). The imprecision of the glucometer was higher than that of the laboratory assay (3.4 vs. 0.8 %). A negative bias of −3.3 % in fasting glucose was found with the glucometer compared to the laboratory measurement. The diagnostic accuracy, sensitivity and specificity of the glucometer for detecting fasting glucose values ≥7.0 mmol/L were 99.2 , 50.0 and 100.0 % compared to the laboratory assay. The glucometer-based strategy had an incremental cost of 0.17€ per patient compared to the laboratory-based strategy. Conclusions Screening fasting glucose in capillary blood with a near-patient glucometer instead of measuring fasting plasma glucose with laboratory instrumentation allows faster patient management in the phlebotomy center but is associated with higher imprecision, inaccuracy, costs and avoidable finger pricks.
