備前市における新型コロナウイルス感染症の抗体検査に関する研究の成果報告

Title Alternative	The results of COVID-19 antibody testing studies in Bizen, Japan
Author	Yorifuji, Takashi\| Sasaki, Ayako\| Matsumoto, Naomi\| Kadowaki, Tomoka\| Mitsuhashi, Toshiharu\| Takao, Soshi\|
Abstract	We conducted two prospective cohort studies (June 2022–March 2023 and Nov 2023–Jan 2024) of 1,899 and 445 residents and other individuals who are affiliated with institutions in the city of Bizen in Japan's Okayama prefecture (population 32,320 as of 2020). We measured the subjects' titers of antibodies against SARS-CoV-2, evaluated changes in their antibody titers, and assessed the associations of the titers with the subjects' vaccination status, infection, and COVID-19 status/severity. This report summarizes the two studies' findings. These prospective studies based on a wide age range in a general population provide information that can be used to determine the appropriate timing of vaccination during a pandemic.

若手・中堅耳鼻咽喉科医師の臨床研究に対する質問紙調査

Title Alternative	Questionnaire survey of junior and mid-career otolaryngologists' attitudes towards clinical research
Author	Uraguchi, Kensuke\| Yorifuji, Takashi\| Takao, Soshi\| Sugaya, Akiko\| Ando, Mizuo\|
Abstract	Introduction : Clinical research is crucial for the advancement of medicine, but modern otolaryngologists' attitudes regarding clinical research have not been known. This study was conducted to survey the background, knowledge, and interest in clinical research among junior and mid-career otolaryngologists. 　Methods : A questionnaire survey was distributed to 34 otolaryngologists with ≤15 years' clinical experience working at Okayama University and its affiliated facilities. The respondents were divided into junior (non-specialists) and mid-career otolaryngologists (specialists) based on whether they were board-certified otolaryngologists. The survey assessed their background, understanding, and interest in clinical research. 　Results : Twenty-nine otolaryngologists (83%) responded (10 junior and 19 mid-career otolaryngologists). There was significant individual variation in their interest and knowledge of clinical research. However, approximately half of the respondents indicated that they were not interested in and/or had never engaged in clinical research. 　Conclusion : The data collected by this survey contribute to our understanding of the current state of clinical research engagement among junior and mid-career otolaryngologists, and they can serve as a basis for exploring future strategies to increase this engagement.
