Background: In Poland, the consumption of energy drinks among young people has changed significantly following the introduction of a ban on sales to minors. This regulatory measure was intended to address growing concerns about the health effects of high caffeine consumption among teenagers. The aim of the study was to assess the frequency, preferences, and determinants of energy drink consumption among Polish adolescents aged 15–17 years, following the introduction of the legal ban on the sale of energy drinks to minors. Methods: The study was conducted in Poland in 2024, following the introduction of a law prohibiting the sale of energy drinks to minors. The study group consisted of 999 high school students aged 15–17 who completed an anonymous, author-designed survey. Data were then collected and analyzed for descriptive statistics, and chi-square tests were used for categorical variables, Mann–Whitney U tests and Kruskal–Wallis tests for group comparisons, and Spearman’s rank correlation for ordinal data. Results: In total, 52% of respondents declared that they consume energy drinks, and 68% reported a reduced intake after the introduction of the regulations prohibiting sales to minors. These drinks are more frequently consumed by males. Additionally, age and frequency of consumption were positively correlated. The factors most often influencing the choice of energy drinks were price, taste, package size, caffeine content, composition, and recommendations from friends. Conclusions: Although a large percentage of minors still consume energy drinks, the new regulations have had an impact on reducing their intake.

Neonatal iron deficiency anemia is prevalent among domestic pigs but does not occur in the offspring of wild boar. The main causes of this disorder in piglets of modern pig breeds are paucity of hepatic iron stores, high birth weight, and rapid growth. Replenishment of fetal iron stores is a direct result of iron transfer efficiency across the placenta. In this study, we attempted to investigate the molecular potential of iron transfer across the placenta as a possible cause of differences between wild boar and Polish Large White (PLW) offspring. Furthermore, by analyzing placentas from PLW gilts that had litters of different sizes, we aimed to elucidate the impact of the number of fetuses on placental ability to transport iron. Using RNA sequencing, we examined the expression of iron-related genes in the placentas from wild boar and PLW gilts. We did not reveal significant differences in the expression of major iron transporters among all analyzed placentas. However, in wild boar placentas, we found higher expression of copper-dependent ferroxidases such as ceruloplasmin, zyklopen, and hephaestin, which facilitate iron export to the fetal circulation. We also determined a close co-localization of ceruloplasmin and zyklopen with ferroportin, the only iron exporter.
