Key Points Question Do self-collected and health care worker (HCW)–collected throat swab specimens improve the accuracy of COVID-19 rapid antigen testing compared with nasal swab specimens? Findings In this multicenter randomized clinical trial including 2941 participants (2674 with complete data), HCW-collected throat swabs were more sensitive than nasal specimens for rapid antigen testing; no difference was found between self-collected throat and nasal specimens.

4. Discussion We conducted a systematic review and meta-analysis that examined the HPV+ OCSCC prevalence worldwide. Thirty-one studies were included with a total of 5007 patients. There was a wide variety in the prevalence of HPV+ OCSCC reported, with the lowest prevalence being 0% in the Philippines, the UK, India, the Republic of Korea, and France and the highest being 37% in Jordan [20,22,24,25,33,36,38,40].

Introduction In Western countries, thyroid cancer is the most common endocrine neoplasm and is nearly three times more frequent in females (1–4). The incidence of thyroid cancer has increased substantially since 1980, in parallel with survival rates (1–3). Some studies explain the increase in incidence due to better access to diagnostic imaging including ultrasonography, leading to diagnosis of many asymptomatic thyroid nodules (1,3,5).
