Seymour, Paul and Gloria Milstein Division of Cardiology, Department of Medicine, Columbia University Irving Medical Center and NewYork-Presbyterian Hospital (Y.A.C., M.S., M.C., L.L.J., A.J.E.).
Background: Cardiac diagnostic testing continues to evolve, and controversies remain regarding the optimal utilization of different procedures. We sought to evaluate changes in long-term utilization trends for a wide range of cardiac diagnostic tests in the context of advancing technologies and updated guidelines.
Methods: Annual cardiac testing volumes from 2010 to 2022 in the Medicare Part B population were compared across tests and by provider specialty and analyzed using Joinpoint regression.
Gallbladder perforation due to the obstructing periampullary duodenal diverticulum (Lemmel's syndrome): a case report.

Lemmel's syndrome is a rare condition characterized by obstructive jaundice due to the periampullary duodenal diverticulum in the absence of choledocholithiasis or tumors. Its infrequent occurrence and non-specific clinical presentation can make it difficult to distinguish from other conditions. We present a case of Lemmel's syndrome in a 63-year-old male who exhibited symptoms of abdominal pain in right hypochondrium, vomiting, and fever.

University of Toronto, Department of Medical Biophysics, Toronto, Ontario, Canada.
Purpose: Breast density (BD) and background parenchymal enhancement (BPE) are important imaging biomarkers for breast cancer (BC) risk. We aim to evaluate longitudinal changes in quantitative BD and BPE in high-risk women undergoing dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), focusing on the effects of age and transition into menopause.
Approach: A retrospective cohort study analyzed 834 high-risk women undergoing breast DCE-MRI for screening between 2005 and 2020.

A foamed sodium carboxymethyl cellulose (CMC) material was prepared under nitric acid conditions. Unlike traditional CMC materials, this foaming method is straightforward and does not require additional foaming agents. Owing to its high stability and load capacity, the foam can realize long-term quantitative storage and load a variety of metal ions; therefore, it has broad application prospects in the field of loaded materials for metal ions.
