Effectiveness and adherence to closed face shields in the prevention of COVID-19 transmission: a non-inferiority randomized controlled trial in a middle-income setting (COVPROSHIELD).
Trials
August 2022
Article Synopsis
- - The study investigated the effectiveness of using closed face shields along with surgical masks to reduce the transmission of COVID-19 (SARS-CoV-2) among working adults in Bogotá, Colombia during the pandemic.
- - Participants were randomly divided into two groups: one wore closed face shields with surgical masks while the other group wore only surgical masks, and the primary outcome assessed was the rate of positive COVID-19 test results over a follow-up period of 21 days.
- - Results showed that the closed face shield plus surgical mask combination was not less effective than using just a surgical mask, with very low rates of infection in both groups, suggesting that this method could be suitable for high-risk settings.

Actinic keratosis (AK) lesions are surrounded by field cancerization (areas of subclinical, non-visible sun damage). Existing AK grading tools rely on AK counts, which are not reproducible. An Actinic Keratosis Field Assessment Scale (AK-FAS) for grading the severity of AK/field was developed.
