15. Understanding the geochemical composition of alluvial sediments in a complex environmental system – A case study of the Mura/Mur riverBarbara Čeplak, Ulrike Moser, Johanna Irrgeher, Martin Šala, Polona Kralj, Gorazd Žibret, 2025, original scientific article Abstract: The study provides a comprehensive investigation of the geochemical properties of stream and alluvial sediments in an area characterised by a complex natural (geochemical) and anthropogenic environment of the transboundary Mura River (Austria, Slovenia, EU). A total of 65 sediment samples from active river channel and tributaries, and 59 samples from 6 floodplain sediment profiles were collected and analysed. ICP–MS analysis was used to determine the levels of 59 elements in two fractions (<0.063 and 0.063–0.125 mm). Natural (geological) and anthropogenic factors influencing the elemental composition were determined. The sediments showed a low degree of weathering in the upper part of the river and a moderate degree in the middle and lower parts. They are enriched with As, Co, Cr, Cu, Mo, Ni, and Sb compared to the median values for the European stream and floodplain sediments. This can be a consequence of the presence of natural ore mineralisation in Upper Styria along with related lithological features. Factor analysis revealed four natural geochemical associations (K–Ba–Rb–Ga–Li–Tl–Cs–Be–Al–Cu–V; Th–YREE–U; Zr–Hf–Nb; Na–Sr), one anthropogenic association (Cd–In–Zn–Pb) and two combined (geogenic and anthropogenic) associations (Ni–Cr–Mg–Co–V and Fe–Sc–Ti–Nb). Particle analysis by SEM/EDS was used to identify characteristic carriers of specific elements and potentially to determine their sources.

20. Key differences between chronic inducible and spontaneous urticariaMojca Bizjak, Mitja Košnik, 2024, original scientific article Abstract: Introduction: The latest international EAACI/GA²LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends limited laboratory testing for chronic spontaneous urticaria (CSU) and selective testing for only certain chronic inducible urticaria (CIndU) subtypes, though the rationale for these recommendations is poorly explained. This study aimed to improve the understanding of CIndU subtypes by comprehensively comparing their demographic, clinical, and laboratory characteristics with those of the better-characterized CSU.
Methods: We conducted a retrospective analysis of 567 patients (median age 41 years, 67% female) diagnosed with CSU, symptomatic dermographism (SD), cold urticaria (ColdU), cholinergic urticaria (CholU), and delayed pressure urticaria (DPU).
Results: Our findings revealed that patients with SD, ColdU, and CholU had lower levels of C-reactive protein (CRP), higher total serum immunoglobulin E (IgE) levels, and higher basophil counts compared to CSU patients. These subtypes also had distinct demographic and clinical features, such as a younger age of onset and a longer disease duration. In contrast, patients with DPU had significantly higher CRP levels and neutrophil counts compared to those with CSU.
Discussion: These findings highlight the heterogeneity among chronic urticaria subtypes, suggesting that a tailored approach to laboratory testing may be more effective. The distinct immunological and clinical features observed in CIndU subtypes suggest a need for subtype-specific diagnostic and therapeutic guidelines.
Keywords: blood cell count, C-reactive protein, chronic inducible urticaria, chronic spontaneous urticaria, immunoglobulin E
