Is thymectomy necessary during parathyroidectomy for secondary hyperparathyroidism in patients with end-stage kidney disease?

Background: Guidelines recommend thymectomy at the time of parathyroidectomy for secondary hyperparathyroidism to reduce the likelihood of persistent or recurrent disease. We sought to determine the frequency of thymectomy and explore its impact on recurrence of secondary hyperparathyroidism.

Methods: Using TriNetX, a multi-institutional electronic health record and insurance claims network, we conducted a retrospective cohort study of adults with secondary hyperparathyroidism who underwent parathyroidectomy with or without thymectomy from 2005 to 2023.

Shoe configuration effects on third phalanx and capsule motion of unaffected and laminitic equine hooves in-situ.

Equine shoes provide hoof protection and support weakened or damaged hoof tissues. Two hypotheses were tested in this study: 1) motion of the third phalanx (P3) and hoof wall deformation are greater in laminitic versus unaffected hooves regardless of shoe type; 2) P3 displacement and hoof wall deformation are greatest while unshod (US), less with open-heel (OH), then egg-bar (EB) shoes, and least with heart-bar (HB) shoes for both hoof conditions. Distal forelimbs (8/condition) were subjected to compressive forces (1.
