Objective To assess whether patient age is associated with progression of low-risk papillary thyroid carcinoma (tumor growth or incident metastatic disease) in adults under active surveillance. Evidence Review Eight electronic databases (MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Emcare, PsycINFO, Web of Science, and ClincalTrials.gov) were searched from inception to March 2019, supplemented with a hand search. Two investigators independently screened citations, reviewed full-text articles, and abstracted data. Additional data were sought from authors. Random-effects meta-analyses were performed using incidence data (statistically adjusted for confounders and crude rates). Findings A total of 1658 unique citations were screened, and 62 full-text articles were reviewed, including 5 studies. Three stwas not significantly different. There was no statistically significant heterogeneity in any of the meta-analyses. There were no thyroid cancer-related deaths nor incident distant metastases. Conclusions and Relevance This study suggests that older age may be associated with a reduced risk of primary papillary thyroid carcinoma tumor growth under active surveillance. Incident metastatic disease is uncommon during active surveillance.We report changes in viral load over time in a 27-day old neonate with COVID-19 who presented with fever, cough, and vomiting. SARS-CoV-2 RNA was detected in the nasopharynx, oropharynx, stool, saliva, plasma, and urine. The highest viral RNA copies in nasopharynx decreased over time while viral load in stool remained high. © The Author(s) 2020.
