Wernicke's encephalopathy is associated mainly with malnourishment in alcohol-dependent patients but can be caused also by cancer, Crohn's disease, gastrointestinal surgery or prolonged parenteral nutrition (PN) without adequate supplementation of vitamins. The disorder, with a significant mortality rate of up to 20%, is often associated with the underlying disease and intensifies after administration of non-supplemented PN. Thus, it seems justified to add thiamine to PN admixtures prepared for parenterally fed patients. Due to the lack of data on the stability of thiamine in PN admixtures at concentrations exceeding 60 mg/L, we decided to determine the possibility of adding a high dose of thiamine (800 mg per bag, 320 mg/L) to PN admixtures in order to treat Wernicke's encephalopathy in malnourished patients. ⋯ The treatment of Wernicke's encephalopathy in parenterally fed patients is possible with the use of high thiamine doses (800 mg) added to PN admixtures without a decrease in the drug content above 10% within the first 24 h. It should be emphasized that thiamine as a photosensitive drug must be stored and administered under conditions ensuring light protection.

Elderly patients are being increasingly admitted to the intensive care unit (ICU) for mechanical ventilation (MV) and prevalence of decreased skeletal muscle mass which develop with aging is subsequently increasing. The objective of this study was to identify the association between decreased skeletal muscle mass and extubation failure in patients undergoing long-term MV. ⋯ Decreased skeletal muscle mass was associated with extubation failure after long-term MV for > 7 days. It is important to diagnose decreased skeletal muscle mass in critically ill patients to reduce extubation failure rates.

Randomized Controlled Trial Multicenter Study
Simo decoction versus domperidone suspension for post-pyloric spiral nasoenteric tube placement: A multicenter, randomized, non-inferiority trial.
Leveraging prokinetics to facilitate trans-pyloric migration is a conventional strategy. However, due to restrictions on the use of domperidone suspension, oral prokinetics is relatively modest. The study aims to assess the effectiveness of simo decoction as an alternative to domperidone suspension in facilitating post-pyloric placement of spiral nasoenteric tubes. ⋯ Non-inferiority of simo decoction to domperidone suspension was not confirmed in facilitating post-pyloric placement of spiral nasoenteric tubes. Registration: The trial was registered with the Chinese Clinical Trial Registry at http://www.chictr.org.cn (registration number ChiCTR-INR-17011311).

Patients undergoing veno-arterial extracorporeal membrane oxygenation (VA-ECMO) are likely to be develop malnutrition because of catabolism and protein consumption. Administration of appropriate nutrition to these patients is difficult because of hemodynamic instability and multiorgan failure. The aim of this study was to evaluate the relationship between nutritional supply and clinical outcomes in patients undergoing VA-ECMO. ⋯ In VA-ECMO patients, when the daily average energy intake increased by 10% of the target over 8-14 days, the 90-day mortality decreased by 18%.
