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

The Negative Effects of ‘Too Accurate’ Recommendation Results: A Pilot Study of the Effects of Search Engine Overuse on Chinese Students

Googling, sharing, recommending and assembling knowledge pieces have become ubiquitous in social learning environments. However, there are a number of well-documented research efforts indicating the disadvantages of over-relying on the internet especially during students’ academic studies. While the majority of these research focuses on the overuse of social media, we are interested in the effects of the overuse of the search engine since googling information been synonym with problem-solving for students. And searched results have long been regarded as recommendation. In this paper, we describe our pilot study to examine the extended effects of search engine overuse as well as the perceived information quality. Mixed results were obtained, although most of the preliminary results are mostly consistent with our speculations in the over-use of search engine on students’ academic studies
