In Vitro Calcification Evaluation of Polycarbonate Urethane—Impact of Production Processes

open access: yesArtificial Organs, EarlyView.
The study shows that hot pressing induces chemical changes in PCU, promoting calcification, while solution‐cast patches remain unaffected. ABSTRACT Background Heart valve diseases remain a leading cause of death in industrialized nations. Polycarbonate urethane (PCU) is a promising material for heart valve prostheses due to its biocompatibility and low

Vasoreactivity as a Measure of Kidney Viability During Ex Vivo Normothermic Machine Perfusion

open access: yesArtificial Organs, EarlyView.
This study aimed to investigate the influence of warm ischemic injury on renal vascular responsiveness to vasoactive drugs during normothermic machine perfusion (NMP). We found that the vascular responses to dopamine and norepinephrine could be used as objective indicators to assess kidney viability during NMP.

Evaluation of a Rat Cardiopulmonary Bypass Model Using an Extraluminal Flow Oxygenator

open access: yesArtificial Organs, EarlyView.
A rat cardiopulmonary bypass model was constructed incorporating the developed extraluminal flow oxygenator and compared with a commercial intraluminal flow oxygenator. Both oxygenators demonstrated comparable gas exchange performance and inflammatory responses; however, the one developed in this study better preserved PLT counts.

Sample size determination for hypothesis testing on the intraclass correlation coefficient in a two‐way analysis of variance model

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability evaluation is critical in fields such as psychology and medicine to ensure accurate diagnosis and effective treatment management. When participants are evaluated by the same raters, a two‐way ANOVA model is suitable to model the data, with the intraclass correlation coefficient (ICC) serving as the reliability metric.

From tetrachoric to kappa: How to assess reliability on binary scales

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...
