The indelible marks on dermatology: Impacts of COVID-19 on dermatology residency Match using the Texas STAR database.

With changes to interview format and away rotations, the COVID-19 pandemic has reshaped the residency application process. In this retrospective cohort study of data from the nationwide Texas Seeking Transparency in Applications to Residency (STAR) survey, we sought to understand how the pandemic has affected applicants in the 2021 dermatology Match. We compared applicants in the post-COVID-19 Match year (2021) with those in pre-COVID-19 Match years (2018-2020) regarding match rates, interview costs, residency geographic connections, and number of interviews attended.

C4-aldehyde of guaiazulene: synthesis and derivatisation.

Guaiazulene is an alkyl-substituted azulene available from natural sources and is a much lower cost starting material for the synthesis of azulene derivatives than azulene itself. Here we report an approach for the selective functionalisation of guaiazulene which takes advantage of the acidity of the protons on the guaiazulene C4 methyl group. The aldehyde produced by this approach constitutes a building block for the construction of azulenes substituted on the seven-membered ring.
