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

SPIN-FLIP BETA- DECAY OF EVEN-EVEN DEFORMED-NUCLEI RU-110 AND RU-112

Neutron-rich nuclides Ru-110 and Ru-112 produced in symmetric fission of U-238 by 20 MeV protons have been studied at the IGISOL facility by means of beta-ray, gamma-ray and conversion electron spectroscopy. A total of 12 and 6 gamma-transitions were observed in the decays of Ru-110 and Ru-112, respectively. Multipolarities were determined for a few transitions. The beta decay half-life was determined to be 11.6 +/- 0.6 s for Ru-110 and 1.75 +/- 0.07 s for Ru-112. As a side product, a new value of 2.1 +/- 0.3 s for the beta half-life of the Rh-112 1+ state was obtained. The decay energy measured with the plastic scintillator was 2.81 +/- 0.05 MeV for Ru-110 and 4.52 +/- 0.08 MeV for Ru-112. The beta decay schemes of Ru-110 and Ru-112 isotopes indicate that the main fraction of their beta strength resides in two 0+ --> 1+ spin-flip transitions with their log f t values between 4.4 and 4.7. The decay energies and the energies of the 1+ GT states are compared with the macroscopic-microscopic model calculations. The observed GT-strengths are discussed in the framework of the deformed single-particle model
