Beating heart superior caval vein replacement for giant venous aneurysm: a case report.

Background: Superior vena cava (SVC) aneurysms are rare vascular anomalies, with <80 cases reported worldwide. Large aneurysms carry a risk of rupture and thrombosis, eventually necessitating surgical intervention.

Case Summary: We present the case of a 68-year-old male with a progressively enlarging SVC aneurysm and a history of paroxysmal atrial fibrillation.

An exploration of Michigan certified peer support specialists' perceptions on tobacco use and additional future supports.

Introduction: Certified peer support specialists, recovery coaches and community health workers uniquely connect to individuals who smoke through shared experiences. This study examines peers' perceptions of tobacco cessation supports to enhance policy and intervention opportunities in rural and non-rural communities.

Methods: Peers (n=172) responded to a needs assessment available from 30 November 2023 to 1 February 2024.

Valve-sparing aortic root replacement for valves with paracommissural fenestrations: which valve will fail?

Objectives: To define morphologic risk constellations during valve-sparing aortic root replacement (VSARR) for aortic valves with paracommissural fenestrations.

Methods: Patients from the multicentre prospective intention-to-treat VSARR-registry German Aortic Root Repair Registry (GEARR) were screened for paracommissural cusp fenestrations. We studied a combined end-point of residual aortic regurgitation (rAR) on post-cardiopulmonary bypass (CPB) transesophageal echocardiography (TEE), mid-term progress of rAR (transthoracic echocardiography) and aortic valve replacement for AR.

Spin-orbit interaction driven terahertz nonlinear dynamics in transition metals.

The interplay of electronic charge, spin, and orbital currents, coherently driven by picosecond long oscillations of light fields in spin-orbit coupled systems, is the foundation of emerging terahertz lightwave spintronics and orbitronics. The essential rules for how terahertz fields interact with these systems in a nonlinear way are still not understood. In this work, we demonstrate a universally applicable electronic nonlinearity originating from spin-orbit interactions in conducting materials, wherein the interplay of light-induced spin and orbital textures manifests.
