Palmitoylethanolamide/Luteolin Supplementation in Older Adults Undergoing Cardiac Surgery
Palmitoylethanolamide/Luteolin for the Maintenance of Cognitive Performance in Older Adults Undergoing Cardiac Surgery
Postoperative Cognitive Dysfunction (POCD) is a common complication after surgery, particularly among older adults. It is characterized by cognitive impairment, reduced functional independence, and decreased quality of life. Growing evidence suggests that neuroinflammation plays a relevant role in POCD development and persistence.
Palmitoylethanolamide (PEA) is an endogenous lipid mediator involved in the regulation of neuroinflammatory processes through the modulation of non-neuronal cells, while luteolin is a flavonoid with well-known antioxidant properties. Under conditions of prolonged neuroinflammation, endogenous PEA levels may be insufficient to adequately counteract pro-inflammatory signaling, making exogenous administration necessary.
In this context, exogenous micronized and ultramicronized PEA (mPEA and umPEA) supplementation has been shown to modulate cognitive and executive functions, working memory, language, and activities of daily living. Moreover, the combination of umPEA and luteolin (PEALut) may produce synergistic effects by modulating neuroinflammation and supporting neuronal function.
This study aims to evaluate whether postoperative administration of co-ultramicronized PEA and luteolin (700 mg + 70 mg in 10 mL), added to standard of care, may contribute to the mitigation of POCD in older adults undergoing elective cardiac surgery, compared to standard care alone.

Change in cognitive performance
Временное ограничение: Baseline, hospital discharge (approximately postoperative day 7-10, depending on clinical course), 3 months after treatment, and 3 months after the end of treatment
