    Functional resistomes in municipal wastewater treatment plants pose challenges to public health

    Wastewater treatment plants (WWTPs) are essential for controlling antimicrobial resistance, but also serve as hotspots for resistance gene persistence and dissemination. In this study, a novel combinatory approach using genome-resolved metagenomics and metatranscriptomics was employed to examine the resistome of a full-scale municipal WWTP across treatment stages and seasons. Results reveal that although human-associated, potentially pathogenic, antibiotic resistance gene (ARG)-harbouring metagenome-assembled genomes (ARBMAGs) declined in abundance during treatment, many ARGs remained transcriptionally active, particularly efflux, beta-lactam, and macrolide–lincosamide–streptogramin genes conferring resistance against fluoroquinolones, cephalosporins, and macrolides. Environment and treatment-adapted microbes become increasingly dominant, with plasmids identified as major vectors of mobile resistance. Dominant potential pathogenic human-associated ARBMAGs were abundant during spring and summer, whereas environmental ARBMAGs predominated in colder seasons. Fluoroquinolone resistance genes displayed varying expression levels across ARBMAG types, with the lowest levels observed during the anaerobic phase of treatment. Although clinically relevant ARGs were detected at low relative abundance and expression levels, one of the carriers was Citrobacter freundii ARBMAG, a human-associated potential pathogen. These findings underscore the value of integrating genomic and transcriptomic data to assess site-specific and ARBMAG-type-specific resistance and to strengthen antibiotic resistance monitoring in engineered systems

    Risk and Protective Factors of Depressive Symptoms Among Hungarian Adolescents from a Large Cross-Sectional Survey

    There is a global documented rise in depressive symptoms among adolescents. The cross-sectional assessments in representative samples of adolescents would help explore their correlates, which may serve as resources for intervention. Our cross-sectional survey entitled “Békés County Youth Study 2024” involved a representative sample of grade-9 high school students (N = 1590, aged 15–17 years, 56.4% females) from public high schools in the region, Hungary. Besides depressive symptoms (measured by a validated, shortened version of the Children’s Depression Inventory, CDI), a set of psychosocial variables (psychosomatic symptoms, internet addiction, future orientation, social support from family and friends, marks, gender, school satisfaction, and religiosity) was included in the survey. Gender differences in the summary score for CDI were significant: t(1588) = −12.062, p < 0.001, showing a higher rate of females. A total of 22.6% (males: 13% and females: 30%) belonged to the group at risk of depression. All potential predictors proved significant, with the strongest contribution of psychosomatic symptoms (Beta = 0.306, p < 0.001), and the most relevant protective role of family support (Beta = −0.265, p < 0.001). Other than further exploring contextual factors that increase risk for and protect against adolescent depression, mental health promotion in schools should include well-being training
