Journal of Diabetes, Volume 15, Issue 11, Page 944-954, November 2023., 2023 Highlights Preclinical data showed that dipeptidyl peptidase‐4 inhibitors (DPP‐4is) may prevent insulin‐induced atherosclerosis. In patients treated with insulin for type 2 diabetes who underwent ≥2 serial coronary computed tomography angiographies(CCTA), a new obstructive coronary artery disease (OCAD) was less developed on the follow‐up CCTA in those

Brachycephaly in French bulldogs and pugs is associated with narrow ear canals
Veterinary Dermatology, Volume 33, Issue 3, Page 214-e60, June 2022., 2022 Background Brachycephalic dog breeds have multiple skull malformations which may lead to anatomical changes in the external auditory canal. It is our frequent observation that in the otoscopic examination of the external ear in these breeds we are unable to visualise the tympanic membrane as a consequence of extreme narrowing of the proximal ear canal.
