8. Targeting pediatric obesity through gender-specific nutritional strategies : insights from dietary intake and food sourcesTadeja Jakus, Breda Prunk Franetič, Tamara Poklar Vatovec, 2025, izvirni znanstveni članek Opis: Background/Objectives: Childhood obesity remains a major global health challenge influenced by poor dietary patterns and excessive energy intake. Understanding gender-specific nutritional deviations may improve the effectiveness of preventive and therapeutic interventions. This study aimed to evaluate differences in energy and nutrient intake between boys and girls with overweight or obesity status and to identify the main food sources contributing to these differences. Methods: Data from a total of 180 participants (83 boys, 97 girls; 7–18 years) attending the national obesity intervention program Camp My Challenge was analyzed. Anthropometric parameters and dietary intake were assessed using a validated food-frequency questionnaire (OPKP). Intakes were compared with Slovenian dietary reference values (DRVs). Group differences were tested using ANOVA, t-tests, and Pearson correlations (p < 0.05). Results: Boys exhibited higher body mass (79.9 ± 22.6 kg vs. 69.2 ± 19.1 kg; p = 0.001) and BMI (30.8 ± 4.8 kg/m2 vs. 28.5 ± 4.4 kg/m2; p = 0.001). Mean energy intake was 2543 ± 1138 kcal/day, exceeding DRV by 16% (t = 3.31, p < 0.001). Girls exceeded energy requirements by 24.5% vs. 5.4% in boys (p = 0.019). Boys consumed significantly more total fat (106 ± 61 g vs. 85 ± 47 g; p = 0.014), saturated fatty acids (34 ± 20 g vs. 27 ± 13 g; p = 0.011), protein (119 ± 63 g vs. 98 ± 41 g; p = 0.008), and sodium (3628 ± 2086 mg vs. 2852 ± 1520 mg; p = 0.005). Girls showed higher sugar intake (208% vs. 166% of DRV; p = 0.032), mainly from sweet foods (24%) and fruit (26%), whereas beverages—predominantly isotonic drinks—accounted for 27% of boys’ sugar intake. Sugar intake correlated with waist circumference (r = 0.305, p = 0.002) and fat mass (r = 0.272, p = 0.007) in girls. Sodium intake exceeded DRV sixfold in both sexes. Conclusions: Marked sex-specific dietary disparities exist among children with obesity. Interventions should target high sugar and energy intake in girls and excessive fat, sodium, and sugar-sweetened beverage consumption in boys to enhance the efficacy of pediatric obesity management.

9. Nut digraphsNino Bašić, Patrick W. Fowler, Maxine M. McCarthy, Primož Potočnik, 2026, izvirni znanstveni članek Opis: A nut graph is a simple graph whose kernel is spanned by a single full vector (i.e., the adjacency matrix has a single zero eigenvalue and all non-zero kernel eigenvectors have no zero entry). We classify generalisations of nut graphs to nut digraphs: a digraph whose kernel (resp. co-kernel) is spanned by a full vector is dextro-nut (resp. laevo-nut); a bi-nut digraph is both laevo- and dextro-nut; an ambi-nut digraph is a bi-nut digraph where kernel and co-kernel are spanned by the same vector; a digraph is inter-nut if the intersection of the kernel and co-kernel is spanned by a full vector. It is known that a nut graph is connected, leafless and non-bipartite. It is shown here that an ambi-nut digraph is strongly connected, non-bipartite (i.e., has a non-bipartite underlying graph) and has minimum in-degree and minimum out-degree of at least 2. Refined notions of core and core-forbidden vertices apply to singular digraphs. Infinite families of nut digraphs and systematic coalescence, crossover and multiplier constructions are introduced. Relevance of nut digraphs to topological physics is discussed.

10. Nut graphs with a prescribed number of vertex and edge orbitsNino Bašić, Ivan Damnjanović, 2026, izvirni znanstveni članek Opis: A nut graph is a nontrivial graph whose adjacency matrix has a one-dimensional null space spanned by a vector without zero entries. Recently, it was shown that a nut graph has more edge orbits than vertex orbits. It was also shown that for any even $r \geq 2$ and any $k \geq r + 1$, there exist infinitely many nut graphs with r vertex orbits and k edge orbits. Here, we extend this result by finding all the pairs $(r, k)$ for which there exists a nut graph with $r$ vertex orbits and $k$ edge orbits. In particular, we show that for any $k \geq 2$, there are infinitely many Cayley nut graphs with $k$ edge orbits and $k$ arc orbits.
