[A comparative assessment of neurochemical and neurophysiological parameters of cardiac surgery patients who underwent different versions of multitasking cognitive training].

Objective: To compare biomarkers of neurovascular unit (NVU) - S100β, NSE, BDNF and indicators of the brain electrical activity in patients who underwent coronary artery bypass grafting (CABG) depending on the use of different versions of multi-tasking cognitive training (CT).

Material And Methods: The study included 89 people, of whom 47 completed the CTI (postural and three cognitive tasks (counting backwards, verbal fluency and the open-ended task «Unusual use of an ordinary object») and 42 patients, who underwent CTII (visuomotor reaction and the same cognitive tasks) in the early postoperative CABG period. The patients of both groups underwent complex testing of psychomotor, executive functions, attention, short-term memory and EEG study in the perioperative period of CABG.

[Clinical efficacy of carbohydrate preloading in reconstructive esophageal surgery].

Objective: To evaluate clinical efficacy of preoperative carbohydrate loading as a component of ERAS in esophageal reconstructive surgery.

Material And Methods: Post hoc analysis included 162 patients who underwent esophageal reconstructive interventions with ERAS principles between 2014 and 2024. The main group (=61, CHO+) included patients who were metabolically loaded with carbohydrates in preoperative period with 12.
