Recent studies reported that soluble epoxide hydrolase (sEH) plays an important role in lung diseases. However, the role of sEH in hyperoxia-induced ALI is unclear. ⋯ sEH is a harmful factor for hyperoxic ALI. The beneficial effect of sEH gene deletion is associated with the elevation of EETs and regulation of Nrf2/Keap1 signal pathway.

Bacterial translocation (BT) has been proposed as a trigger for stimulation of the immune system with consequent hemodynamic alteration in patients with liver cirrhosis. However, no information is available regarding its hemodynamic and coagulation consequences during liver transplantation. ⋯ Bacterial translocation was found in one-third of patients at the time of transplantation and was largely associated with increased markers of inflammation along with decreased activity of coagulation factors.

There is increasing interest in whether anesthetic agents affect the risk or progression of Alzheimer's disease (AD). To mitigate many of the methodological issues encountered in human retrospective cohort studies we have used a transgenic model of AD to investigate the effect of propofol on AD pathology. ⋯ These data suggest that repeat propofol anesthesia may not exacerbate plaque deposition or associated synapse loss in AD. Interestingly, this data also provides some of the first evidence suggesting that repeat propofol exposure in adult wild-type mice does not result in robust long-term alterations in the levels of key excitatory and inhibitory synaptic markers.

Despite risks, complications and negative impact to quality of life, tracheostomy is widely used to bypass upper airway obstruction after major oral cancer surgery (MOCS). Decision to tracheostomy is frequently based on clinical scoring systems which mainly have not been validated by different cohorts. Delayed extubation in the Intensive Care Unit (ICU) may be a suitable alternative in selected cases. We hypothesize that delayed routine ICU extubation after MOCS instead of scoring system based tracheostomy is safe, feasible and leads to lower tracheostomy rates. ⋯ Our data demonstrate that common clinical scoring systems fail to prevent tracheostomy in patients after MOCS. Application of scoring systems may lead to a higher number of unnecessary tracheostomies. Delayed routine extubation in the ICU after MOCS seems an appropriate and safe approach to avoid tracheostomy and the related morbidity.

Randomized Controlled Trial
Dexmedetomidine infusion as an analgesic adjuvant during laparoscopic сholecystectomy: a randomized controlled study.
Dexmedetomidine (DEX) has sedative, sympatholytic and analgesic effects and might be beneficial if used as an adjuvant to: improve analgesia; modulate haemodynamic responses to intubation and pneumoperitoneum and; reduce the number of opioid-associated adverse events. The aim of this study was to evaluate the efficacy and safety of DEX infusion during elective laparoscopic cholecystectomy (LC). ⋯ Intraoperative DEX infusion is safe and effective for improving analgesia during and after elective LC. DEX appears to significantly reduce the number of patients with severe postoperative pain, postoperative morphine consumption and prolong time to first use of rescue analgesia.
