Effect of drug therapies on self-reported chemosensory outcomes after COVID-19.

Objective: The aim of this study was to assess the relative efficacy of medications used following severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection on self-reported alterations in taste and/or smell function.

Methods: Seven hundred and fourteen persons with self-reported postcoronavirus disease 2019 (post-COVID-19) chemosensory disorders were personally interviewed regarding specific medications they were administered following the acute phase of the disease. The dependent measure-self-reported total recovery of chemosensory symptoms-was subjected to stepwise logistic regression.

Association of air pollution with olfactory identification performance of São Paulo residents: a cross-sectional study.

Objective: Exposure to particulate matter of 10 μm or less in diameter (PM) has been implicated in pulmonary and cardiovascular diseases. However, the effect of PM on olfaction has not been well established. We estimated individual acute and chronic PM exposure levels in a large Brazilian cohort and related them to the ability to identify odors.
