Validation of mitochondrial FMN as a predictor for early allograft dysfunction and patient survival measured during hypothermic oxygenated perfusion.

Hypothermic oxygenated machine perfusion (HOPE) preconditions liver grafts before transplantation. While beneficial effects on patient outcomes were demonstrated, biomarkers for viability assessment during HOPE are scarce and lack validation. This study aims to validate the predictive potential of perfusate flavin mononucleotide (FMN) during HOPE to enable the implementation of FMN-based assessment into clinical routine and to identify safe organ acceptance thresholds.

Dual hypothermic oxygenated machine perfusion of the liver reduces post-transplant biliary complications: a retrospective cohort study.

Background: Corroborating evidence for the use of hypothermic oxygenated machine perfusion (HOPE) prior to orthotopic liver transplantation (OLT) suggests a beneficial effect in regard to biliary complications. Here, the authors aim to evaluate whether perfusion via portal vein alone (sHOPE) or via additional perfusion of the hepatic artery (dHOPE) have diverging impact on outcomes after OLT when compared to the use of static cold storage (SCS).

Methods: Consecutive patients undergoing OLT at the Medical University of Vienna (2018-2023) were retrospectively analyzed.

A Multi-Centre Non-Interventional Study to Assess the Tolerability and Effectiveness of Extended-Release Tacrolimus (LCPT) in De Novo Liver Transplant Patients.

Background: Available tacrolimus formulations exhibit substantial inter- and intra-individual variability in absorption and metabolism. The present non-interventional cohort study aimed to assess the tolerability and effectiveness of the once-daily tacrolimus formulation, LCPT, in hepatic allograft recipients in real life.

Materials And Methods: This study was conducted in Austria and the Czech Republic between July 2016 and August 2019.

Advances in diastema closure and tooth shape change using direct composite restorations: the Front Wing Technique.

Closing a diastema with a direct composite restoration still represents a real challenge for clinicians, mainly due to the need to create a correct contact point and emergence profile at the cervical level. The present article describes a novel anterior direct composite restoration technique for closing diastemata and changing tooth shape. The proposed technique, called the Front Wing Technique (FWT), does away with the use of the traditional wax-up and silicone index-based procedures.

HPV screening in the urine of transpeople - A prevalence study.

Background: There is limited data on human papillomaviruses (HPV) prevalence in transpeople due to low acceptance rate of screening methods. HPV tests from self-collected urine are gender-neutral, have a high acceptance, and have a comparable accuracy in females to clinician-collected samples. The aim of this study was to evaluate both the HPV prevalence in the urine in a large cohort of 200 transpeople with common risk profiles and the acceptability of such screening method.
