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

Bypassing adverse injection reactions to nanoparticles through shape modification and attachment to erythrocytes

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Intravenously injected nanopharmaceuticals induce adverse cardiopulmonary reactions in sensitive human subjects and these reactions are reproducible in pigs. The underlying mechanisms are poorly understood, but a role for both the complement system and reactive macrophages has been implicated. Here we show the dominance and importance of early pulmonary intravascular macrophage clearance kinetics in adverse particle-mediated cardiopulmonary distress in pigs and irrespective of complement activation. Delaying particle recognition by macrophages within the first few minutes of injection overcome adverse reactions in pigs. This was achieved by two independent approaches: (i) changing particle geometry from a spherical shape (which trigger cardiopulmonary distress) to either rod- or disk-shape morphology and (ii) by physically adhering spheres to the surface of erythrocytes. These approaches bypasses particle surface engineering approaches to prevent robust macrophage recognition as well as the use of immunological or pharmacological modulators to reduce/overcome nanomedicine related adverse cardiopulmonary distress
