<P><B>Abstract</B></P><P><B>Aims</B></P><P>To identify the effect of early revascularization on 5-year survival in patients with CAD diagnosed by coronary-computed tomographic angiography (CCTA).</P><P><B>Methods and results</B></P><P>We examined 5544 stable patients with suspected CAD undergoing CCTA who were followed a median of 5.5 years in a large international registry. Patients were categorized as having low-, intermediate-, or high-risk CAD based on CCTA findings. Two treatment groups were defined: early revascularization within 90 days of CCTA (<I>n</I> = 1171) and medical therapy (<I>n</I> = 4373). To account for the non-randomized referral to revascularization, we developed a propensity score by logistic regression. This score was incorporated into Cox proportional hazard models to calculate the effect of revascularization on all-cause mortality. Death occurred in 363 (6.6%) patients and was more frequent in medical therapy. In multivariable models, when compared with medical therapy, the mortality benefit of revascularization varied significantly over time and by CAD risk (<I>P</I> for interaction 0.04). In high-risk CAD, revascularization was significantly associated with lower mortality at 1 year (hazard ratio [HR] 0.22, 95% confidence interval [CI] 0.11–0.47) and 5 years (HR 0.31, 95% CI 0.18–0.54). For intermediate-risk CAD, revascularization was associated with reduced mortality at 1 year (HR 0.45, 95% CI 0.22–0.93) but not 5 years (HR 0.63, 95% CI 0.33–1.20). For low-risk CAD, there was no survival benefit at either time point.</P><P><B>Conclusions</B></P><P>Early revascularization was associated with reduced 1-year mortality in intermediate- and high-risk CAD detected by CCTA, but this association only persisted for 5-year mortality in high-risk CAD.</P>

This case study introduces the integration of Mathematics and Arts within a STEAM (Science, Technology, Engineering, Art, and Mathematics) project, focusing on the exploration of human body proportions and body-image perceptions. Through a project-based learning approach, a team of Swedish teachers collaboratively designed and implemented a curriculum that not only illustrates the Maths-Art relationship but also addresses the broader social and cultural implications of body image. This paper outlines the project's methodology, emphasising hands-on activities, critical thinking, and transformative learning experiences that connect real-life and artistic perspectives. By engaging students in a comprehensive exploration of body-image through historical, cultural, and mathematical lenses, the project aimed to foster a healthier understanding of body diversity. The transdisciplinary approach adopted by the teachers at Tångvalla School in Sweden serves as a model for integrating STEAM education in addressing contemporary educational and societal challenges.

When aiming for an increased and more sustainable use of metals a thorough knowledge of the corrosion phenomenon as function of the local metal microstructure is of crucial importance. In this work, we summarize the information presented in our previous publications[1-3] and present an overview of the different local (electrochemical) techniques that have been proven to be effective in studying the relation between different microstructural variables and their different electrochemical behavior. Atomic force microscopy (AFM)[1], scanning electrochemical microscopy (SECM)[2], and electrochemical scanning tunneling microscopy (EC-STM)[3] were used in combination with electron backscatter diffraction (EBSD). Consequently, correlations could be identified between the grain orientation and grain boundary characteristics, on the one hand, and the electrochemical behavior on the other hand. The grain orientation itself has an influence on the corrosion, and the orientation of the neighboring grains also seems to play a decisive role in the dissolution rate. With respect to intergranular corrosion, only coherent twin boundaries seem to be resistant.
