This procedure is carried out via a full sternotomy using standard aortic and bicaval cannulations. For the aortic and pulmonary anastomoses, selective antegrade unilateral cerebral perfusion is used after cooling the body temperature to 26 °Celsius. A 12-mm Hancock conduit is interposed between the pulmonary artery and the proximal descending aorta using standard running suture techniques. Critical decisions during the challenging postoperative management include, but are not limited to, the use of venovenous extracorporeal membrane oxygenation for intermittent support in case of systemic deoxygenation and the anticoagulation and antiplatelet regimen to provide optimal long-term function of the intermittently opening Hancock valve.

Background And Aims: The relationship between the triglyceride-glucose (TyG) index and the incidence of atrial fibrillation (AF) remains insufficiently explored. This investigation aims to elucidate the association between the TyG index and the long-term risk of developing AF.
Methods And Results: This cohort study analyzed data from 409,705 participants sourced from the UK Biobank database.
Intelligent antibacterial coatings based on sensitive response and periodic fast drug release for long-term defense against corrosion induced by sulfate-reducing bacteria.

Pitting corrosion caused by sulfate-reducing bacteria (SRB) significantly shortens the lifespan of metallic pipelines. Antibacterial coatings containing S-responsive drug-loaded nanocontainers represent a promising method to mitigate SRB corrosion. However, the challenge of balancing rapid bactericide release with continuous antibacterial effect limits their practical application.

Article Synopsis
- The study focuses on the outcomes of aortic valve replacement (AVR) in young Moroccan patients with severe aortic regurgitation and impaired left ventricle function.
- A total of 42 out of 110 patients with significant aortic regurgitation and an ejection fraction of ≤35% underwent AVR, showing a low immediate postoperative mortality rate of 4.7%.
- Long-term follow-up indicated a high survival rate of 86.8% after 15 years, along with significant clinical improvements and increased left ventricle ejection fraction post-surgery.

Objective: To compare outcomes of aortic valve replacement (AVR) in patients with pure aortic stenosis (Pure AS) and those with pure aortic regurgitation (Pure AR) or mixed AS and AR (MAVD) in the COMMENCE trial.
Methods: Of 689 patients who underwent AVR in the COMMENCE trial, patients with moderate or severe AR with or without AS (Pure AR + MAVD; n = 135) or Pure AS (n = 323) were included. Inverse probability of treatment weighting Kaplan-Meier survival curves were used for time-to-event endpoints, and longitudinal changes in hemodynamics were evaluated using mixed-effects models.
