Article Abstract
Objectives: This study aims to explore the potential efficacy of the Freestyle Medtronic bioroot in the treatment of aortic endocarditis, based on our single-centre experience.
Methods: In this retrospective study conducted between 2015 and 2023, adult patients who underwent aortic root replacement with coronary arteries reimplantation using the modified Bentall technique with a Medtronic Freestyle bioroot in our centre for infective endocarditis were included.
Results: Thirty patients, with five deaths, no cases of relapse and two cases of reinfection, were included, and prosthetic valve endocarditis represented 73.3% of cases. The median age was 66 years (IQR 14.5 years), and 24/30 (80%) were male. Median EuroSCORE II was 12.2% (IQR 13.9%). The most commonly identified pathogen was Staphylococcus aureus (eight cases; 23.3%). Fourteen additional procedures were performed on 12 patients. Annular abscess was present in 73.3% of cases and required annulus patch repair in 13/22 (59%). Early reoperation rate was 20%, mostly for surgical bleeding. One- and 5-year actuarial survival rates were 90.0 and 82.2%, respectively. There were no cases of relapse, and reinfection-free survival was 86.7% at 1 year and 75.5% at 5 years. Postoperative mean and maximal transvalvular gradients were 7 (IQR 3.3 mmHg) and 14.6 mmHg (IQR 4.6 mmHg), respectively.
Conclusions: The Medtronic Freestyle bioroot could be a valid alternative to homografts for the treatment of infective endocarditis, particularly in cases necessitating aortic root reconstruction after extensive debridement of annular abscesses, with comparable outcomes and potential advantages in terms of durability and availability.

Introduction: Continuous glucose monitoring (CGM) provides real-time glucose data for people with diabetes. However, detailed knowledge of its use in daily life remains limited. We aim to investigate the interaction between people with type 1 diabetes (T1D) and their CGM data and the impact of the interaction on glycaemia and diabetes distress.

Background: Continuous glucose monitoring (CGM) promotes glycemic benefits in adults with type 2 diabetes (T2D), including insulin users as well as noninsulin users, often with minimal professional support. To investigate whether these benefits may stem from increased user engagement in self-management, we conducted a randomized controlled trial comparing the impact of CGM versus self-monitoring of blood glucose (SMBG) on self-reported engagement and HbA1c in CGM-naïve adults with T2D.
Methods: Potential participants completed the Impact of Glucose Monitoring on Self-Management Scale (IGMSS) and an HbA1c home test to confirm eligibility (>7.

Introduction: Gestational diabetes is a common metabolic disorder in pregnancy which identifies a substantial increased risk of future diabetes. Despite this risk, many individuals are not screened for dysglycaemia in the postpartum period. Continuous glucose monitoring (CGM) is an evolving technology that provides details of an individual's glucose levels throughout the day; however, it has not yet been evaluated as a screening tool for postpartum dysglycaemia.

Attaining an adequate glycemic control has been associated with a better prognosis and with a reduction in the risk of developing long-term microvascular and macrovascular diabetic complications. Continuous glucose monitoring (CGM) has been shown to improve glycemic control and reduce blood glucose variability. Furthermore, CGM is associated with greater treatment adherence and higher satisfaction.

Introduction: Aortic root pathologies needing full aortic root replacement are challenging entities correlated to high morbidity and mortality due to their complexity and mostly refer to high-risk patients. In this retrospective study, we report our surgical experience and clinical results of patients undergoing a Bentall procedure as primary or reoperative surgery with the application of aortic bioconduits.
Methods: Patients who underwent full aortic root replacement utilizing either BioIntegral (BI) or Medtronic Freestyle™ (FS) bioconduit in the Cardiothoracic Surgery Department of the University Hospital Aachen RWTH from January 2015 until September 2020, in an urgent or emergency setting, were analyzed and followed up until December 2023.
