Multicenter StudyDo olfactory and gustatory psychophysical scores have prognostic value in COVID-19 patients? A prospective study of 106 patients.
The lack of objective data makes it difficult to establish the prognostic value of chemosensitive disorders in coronavirus disease 2019 (COVID-19) patients. We aimed to prospectively monitor patients diagnosed with COVID-19 to see if the severity of olfactory and gustatory dysfunction associates with subsequent disease severity. ⋯ Initial objective olfactory and gustatory scores do not seem to have a significant prognostic value in predicting the severity of the COVID-19 course; however, persistence of olfactory dysfunction at 20 days, associated with a more severe course. Unfortunately, olfactory and gustatory dysfunction do not seem to hold prognostic value at the time of initial diagnosis.

Multicenter StudyThe first Canadian experience with the Afirma® gene expression classifier test.
Thyroid nodules are common and often benign, although prove to be malignant upon surgical pathology in 5-15% of cases. When assessed with ultrasound-guided fine-needle aspiration (USFNA), 15-30% of the nodules yield an indeterminate result. The Afirma® gene expression classifier (AGEC) was developed to improve management of indeterminate thyroid nodules (ITNs) by classifying them as "benign" or "suspicious." Objectives were (1) to assess the performance of the AGEC in two Canadian academic medical centres (2), to search for inter-institutional variation and (3) to compare AGEC performance in Canadian versus American institutions. ⋯ Molecular analysis is increasingly used in the management of indeterminate thyroid nodules. This study highlights the experience of two Canadian centres with AGEC testing. We found inter-institutional variability in the rate of nodules returning as "benign," however we found similar rates of confirmed malignancy in nodules returning as "suspicious." According the literature, results for AGEC testing in two Canadian institutions align with results reported in American centres.
