Validation of the questionnaire of olfactory disorders (QOD) for the Brazilian population.

Background: The incidence of olfactory disorders has increased in recent years, mainly related to COVID-19 infection. In Brazil, over 37 million cases of COVID-19 have been reported, and approximately 10 % of those cases continue to experience olfactory disorders for more than one month. Despite the significant negative impact on well-being, there is currently no validated instrument to assess how olfactory disorders impact the quality of life in Brazil.

Oral cancer incidence rate is associated with access to dental care: City and statewide analyses.

Introduction: Access to dental care may affect diagnosis of oral squamous cell carcinoma (OSCC). We tested whether the incidence rate of OSCC is higher in regions with less dental care access in the city of Chicago and state of Illinois.

Study Design: Ecological cohort.

Air pollution is associated with increased incidence-rate of head and neck cancers: A nationally representative ecological study.

Introduction: Early studies show conflicting findings regarding particulate matter ≤ 2.5 μm in diameter (PM) exposure and development of head and neck cancers (HNC). We analyzed the relationship between PM exposure and various types of HNC in a nationally representative ecological sample.

Air pollution exposure is associated with rhinitis in older US adults via specific immune mechanisms.

Background: Pathophysiology of rhinitis in older adults is largely unknown. We tested whether air pollution is associated with this condition and how immune mechanisms may play a role in this relationship.

Methods: We analyzed cross-sectional data from the National Social Life, Health, and Aging Project, a nationally representative study of older adults born between 1920 and 1947.

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.
