Povzetek: Rak debelega črevesa in danke lahko napreduje v oligometastatsko bolezen. Napredki v zgodnjem odkrivanju in intenzivnem sistemskem zdravljenju omogočajo čedalje boljše odgovore na zdravljenje in dolgoročno sistemsko kontrolo bolezni. Pojavlja se vprašanje dolgoročnega vodenja oligometastatskih bolnikov. Kirurška resekcija zasevkov lahko pripomore k izboljšanem preživetju, omogoča kurativnost posega ali podaljša interval brez sistemskega zdravljenja, je pa pogosto omejena z anatomijo, invazivnostjo in morbiditeto takšnega pristopa. Stereotaktično obsevanje (SBRT) zasevkov omogoča zelo učinkovito in natančno zdravljenje zasevkov v nizkem številu obsevalnih odmerkov in s tem zelo dobro in dolgoročno lokalno kontrolo z minimalno invazivnostjo in morbidnostjo. Ta prikaz primera prikazuje zgodbo bolnika, zdravljenega na Onkološkem inštitutu v Ljubljani.

Povzetek: Efficient movements require intact motor and cognitive function. There is a growing literature on motor-cognitive interventions to improve the overall quality of life of healthy or diseased older people. For such interventions, novel technological advances are crucial not only in terms of motivation but also to improve the user experience in a multi-stimuli world, usually offered as a mixture of real and virtual environments. This article provides a classification system for movement-related research dealing with motor-cognitive interventions performed in different extents of a virtual environment. The classification is divided into three categories: (a) type of digital device with the associated degree of immersiveness provided; (b) presence or absence of a human-computer interaction; and (c) activity engagement during training, defined by activity >1.5 Metabolic Equivalent of task. Since virtual reality (VR) often categorizes different technologies under the same term, we propose a taxonomy of digital devices ranging from computer monitors and projectors to head-mounted VR technology. All immersive technologies that have developed rapidly in recent years are grouped under the umbrella term Extended Reality (XR). These include augmented reality (AR), mixed reality (MR), and VR, as well as all technologies that have yet to be developed. This technology has potential not only for gaming and entertainment, but also for research, motor-cognitive training programs, rehabilitation, telemedicine, etc. This position paper provides definitions, recommendations, and guidelines for future movement-related interventions based on digital devices, human-computer interactions, and physical engagement to use terms more consistently and contribute to a clearer understanding of their implications.

Povzetek: This paper presents a study on the influence of different amounts of alkalis (K2O and Na2O) on clinker phase formation, microstructure, phase composition and reactivity of belite-sulfoaluminate cement clinker. Using X-ray powder diffraction and scanning electron microscopy with energy dispersive spectrometry, it was found that the amount of C2S and C4AF increases with the incorporation of alkalis, while the amount of C4A3Ś and CŚ decreases. In addition to the major phases, the samples with alkalis also consist of minor phases such as C3A (tricalcium aluminate), KŚ (arcanite), and KC2Ś3 (Ca-langbeinite). The major ions in the major phases were substituted by alkali cations and some other ions (Ca2+, Al3+, Fe3+, S2-, S6+, Si4+). The alkalis also affect the microstructure of the clinker, e.g., the shape of the grains. Consequently, isothermal calorimetry was used to detect differences in hydration kinetics. The clinker with 2 wt. % K2O content was the most reactive, while the sample with 0.5 wt. % Na content was the least reactive. The latter was primarily influenced by the content of the main and minor phases of the clinker.
