Systematic review and meta-analysis of the evidence for oral nutritional intervention on nutritional and clinical outcomes during chemo(radio)therapy: current evidence and guidance for design of future trials

Conclusion: This systematic review suggests an overall positive effect of nutritional interventions during chemo(radio)therapy on BW. Subgroup analyses showed effects were driven by high-protein n-3 PUFA-enriched ONS, suggesting the benefit of targeting metabolic alterations. DC and/or high-energy ONS were less effective, likely due to cumulative caloric deficits despite interventions. We highlight the need and provide recommendations for well-designed RCT to determine the effect of nutritional interventions on clinical outcomes, with specific focus on reaching nutritional goals and providing the right nu

Cardioprotective mechanism of ω-3 fatty acid icosapent ethyl (IPE) in cardiomyocytes: role in high glucose and shear stress-induced mechano-transduction dysregulation

Conclusion: Our results demonstrate a cardioprotective role of IPE through modulation of hyperglycaemia-induced mechano-transduction dysregulation, inflammation, and oxidative stress. Additionally, our results on a shear stress model showing that IPE restores upstream regulators of YAP/TAZ and reduces disturbed flow-induced activation of pro-inflammatory pathways, suggest that IPE may exert a therapeutic effect on cardiovascular disorders associated with disturbed blood flow and hemodynamic stress.
