Endovascular abdominal aortic aneurysm repair (EVAR) outcomes of unibody and single/double docking limb endografts in Medicare beneficiaries between 2012 and 2018.

Objective: The evaluation of perioperative and long term outcomes for endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) using anatomic (unibody) and proximal neck fixated (docking limbs) endografts across consecutive time cohorts.

Design: This study compares the outcomes of EVAR in Medicare patients stratified by mode of fixation.

Methods: All patients who underwent EVAR between 2012 and 2018 were identified in the Medicare database.

The effects of low-dose, high-LET radiation exposure on three models of behavior in C57BL/6 mice.

To investigate the behavioral consequences of exposure to whole-body irradiation such as might occur for astronauts during space flight, female C57BL/6 mice were exposed to 0, 0.1, 0.5 or 2 Gy accelerated iron ions (56Fe, Z = 26, beta = 0.
