11. General position problems in strong and lexicographic products of graphsPakanun Dokyeesun, Sandi Klavžar, Dorota Kuziak, Jing Tian, 2026, original scientific article Abstract: Outer, dual, and total general position sets are studied on strong and lexicographic products of graphs. Sharp lower and upper bounds are proved for the outer and the dual general position number of strong products and several exact values are obtained. For the lexicographic product, the outer general position number is determined in all the cases, and the dual general position number is established in many cases. The total general position number is determined for both products. Along the way some results on outer general position sets are also derived.
Keywords: outer general position, dual general position, total general position, strong product, lexicographic product

14. IFSO Worldwide Survey 2020–2021 : current trends for bariatric and metabolic proceduresLuigi Angrisani, Antonella Santonicola, Paola Iovino, Rossella Palma, Lilian Kow, 2024, original scientific article Abstract: Purpose: This IFSO survey aims to describe the current trends of metabolic and bariatric surgery (MBS) reporting on the number and types of surgical and endoluminal procedures performed in 2020 and 2021, in the world and within each IFSO chapter. Methods: All national societies belonging to IFSO were asked to complete the survey form. The number and types of procedures performed (surgical and endoluminal interventions) from 2020 to 2021 were documented. A special section focused on the impact of COVID-19, the existence of national protocols for MBS, the use of telemedicine, and any mortality related to MBS. A trend analysis of the data, both worldwide and within each IFSO chapter, was also performed for the period between 2018 and 2021. Results: Fifty-seven of the 74 (77%) IFSO national societies submitted the survey. Twenty-four of the 57 (42.1%) reported data from their national registries. The total number of surgical and endoluminal procedures performed in 2020 was 507,806 and in 2021 was 598,834. Sleeve gastrectomy (SG) remained the most performed bariatric procedure. Thirty national societies (52%) had regional protocols for MBS during COVID-19, 61.4% supported the use of telemedicine, and only 47.3% collected data on mortality after MBS in 2020. These percentages did not significantly change in 2021 (p > 0.05). Conclusions: The number of MBS markedly decreased worldwide during 2020. Although there was a positive trend in 2021, it did not reach the values obtained before the COVID-19 pandemic. SG continued to be the most performed operation. Adjustable gastric banding (AGB) continues to decrease worldwide.

17. Genome-wide association study identifies ABCG1 as a susceptibility locus for tick-borne encephalitisPiyush G. Gampawar, Manfred G. Sagmeister, Daniel Ruzek, Nina A. Schweintzger, Edith Hofer, Benno Kohlmaier, Vendula Švendová, Petra Bogovič, Franc Strle, 2025, original scientific article Abstract: Tick-borne encephalitis (TBE) is a viral infection of the central nervous system, caused by the tick-borne encephalitis virus (TBEV) presenting clinically as meningitis, meningoencephalitis, and meningoencephalomyelitis. To investigate genetic susceptibility to TBE, and its severe forms, we conducted a genome-wide association study in the European population comprising 1,600 TBE cases and 9,699 controls. We identified several suggestive (p < 1 × 10−5) intronic and exonic variants in ABCG1, the only gene significantly associated with TBE susceptibility. These variants were shown to influence ABCG1 expression in peripheral blood, a finding corroborated by RNA expression analysis. In vitro inhibition or silencing of ABCG1 significantly reduced TBEV replication in both neuronal cells and macrophages, highlighting the potential role of ABCG1 in TBEV biology. Additionally, we detected a genome-wide significant variant within TEX41, located downstream of ZEB1, associated with severe forms of TBE. These findings provide novel insights into the genetic factors underlying TBE susceptibility and severity.
