International Consensus Statement on Rhinology and Allergy: Rhinosinusitis

Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods: ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS

Death receptor pathway activation and increase of ROS production by the triple epigenetic inhibitor, UVI5008

"Deregulation of the epigenome is recognized as cause of cancer and epigenetic factors are receiving major attention as therapeutic targets; yet, the molecular mode of action of existing epi-drugs is largely elusive. Here, we report on the decryption of the mechanism of action of UVI5008, a novel epigenetic modifier, that inhibits histone deacetylases, sirtuins, and DNA methyltransferases. UVI5008 highly efficiently induces cancer cell-selective death in a variety of models and exerts its activities in several human tumor xenografts and genetic mouse models of human breast cancer in vivo. Its anticancer activity involves independent activation of death receptors and reactive oxygen species production. Importantly, UVI5008 action is not critically dependent on p53, Bcl-2 modifying factor, and\/or TNF-related apoptosis-inducing ligand as cell death is efficiently induced in cells mutated or deficient for these factors limiting the risk of drug resistance development and maximizing its application spectrum. The simultaneous modulation of multiple (epigenetic) targets promises to open new avenues with unanticipated potential against cancer.
