Biomarkers of mitochondrial dysfunction in autism spectrum disorder: A systematic review and meta-analysis

Conclusion: The fact that alterations in mitochondrial metabolism may be found during pregnancy and early in the life of individuals who eventually develop ASD provides promise for early life predictive biomarkers of ASD. Further studies may improve the understanding of the role of the mitochondria in ASD by better defining subgroups and understanding the molecular mechanisms driving some of the unique changes found in mitochondrial function in those with ASD.

Prophylactic treatment with coenzyme Q10 in patients undergoing cardiac surgery: could an antioxidant reduce complications? A systematic review and meta-analysis

Conclusion: Since none of the clinical trials included in this review report any adverse effects associated to CoQ10 administration, and coenzyme Q10 has been demonstrated to be safe even at much higher doses in other studies, we conclude that CoQ10 should be considered as a prophylactic treatment for preventing complications in patients undergoing cardiac surgery with cardiopulmonary bypass. However, better quality randomized, controlled trials are needed to clarify the role of CoQ10 in patients undergoing cardiac surgery with cardiopulmonary bypass.

Evaluating the efficacy of ubiquinol in heart failure patients: a systematic review and meta-analysis

Conclusion: Results: Among 16 studies, CoQ-10 significantly reduced HF-related mortality by 40% and improved exercise capacity in patients with HF, but demonstrated no significant difference in LVEF however, the potential of its efficacy on LVEF could not be ruled out. Conclusion: CoQ-10 significantly enhances exercise capacity and reduces HF-related mortality; however, its impact on patients with reduced LVEF requires further investigation.
