Routine wastewater-based monitoring of antibiotic resistance in two Finnish hospitals : focus on carbapenem resistance genes and genes associated with bacteria causing hospital-acquired infections

Background: Wastewater-based monitoring represents a useful tool for antibiotic resist-ance surveillance. Aim: To investigate the prevalence and abundance of antibiotic resistance genes (ARGs) in hospital wastewater over time. Methods: Wastewater from two hospitals in Finland (HUS1 and HUS2) was monitored weekly for nine weeks (weeks 25-33) in summer 2020. A high-throughput real-time poly-merization chain reaction (HT-qPCR) system was used to detect and quantify 216 ARGs and genes associated with mobile genetic elements (MGEs), integrons, and bacteria causing hospital-acquired infections (HAIs), as well as the 16S rRNA gene. Data from HT-qPCR were analysed and visualized using a novel digital platform, ResistApp. Eight carbapenem resistance genes (blaGES, blaKPC, blaVIM, blaNDM, blaCMY, blaMOX, blaOXA48, and blaOXA51) and three genes associated with bacteria causing HAIs (Acinetobacter bau-mannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa) were studied. Findings: There was a significantly higher number of ARGs at both hospitals in weeks 27-30 (174-191 genes) compared to other sampling weeks (151-171 genes). Our analyses also indicated that the two hospitals, which used different amounts of antibiotics, had significantly different resistance gene profiles. Carbapenem resistance genes were more prevalent and abundant in HUS1 than HUS2. Across both hospitals, blaGES and blaVIM were the most prevalent and abundant. There was also a strong positive association between blaKPC and K. pneumoniae in HUS1 wastewater. Conclusion: Routine wastewater-based monitoring using ResistApp can provide valuable information on the prevalence and abundance of ARGs in hospitals. This helps hospitals understand the spread of antibiotic resistance in hospitals and identify potential areas for intervention. (c) 2021 The Authors.

Gendered differences in experiences of bullying and mental health among transgender and cisgender youth

Abstract Even though previous studies have shown that transgender youth have poorer mental health and more experiences of being bullied than their cisgender counterparts, and that bullying associates with poorer mental health, knowledge on such associations in different gender identity groups is scarce. This study investigated how mental health problems and experiences of being bullied appear across different gender identity groups, and how bullying is associated with mental health among the groups in question. Data from the Finnish School Health Promotion 2021 study (n = 152,880, mean age 16.2 years (standard deviation 1.22)) was used and categorized into four gender identity groups: cisgender girls (n = 76,521), cisgender boys (n = 69,735), transfeminine youth (n = 1317), and transmasculine youth (n = 5307). Transgender youth experienced more bullying and reported poorer mental health than cisgender youth. While transfeminine youth faced the most bullying, transmasculine youth had the most mental health symptoms. In each group, bullying associated with poorer mental health. Compared to cisgender boys without bullying experiences, odds of poorer mental health were dozens-fold among transmasculine youth with weekly bullying experiences. In addition, compared to cisgender boys with bullying experiences, odds of poorer mental health were greater among all other gender identity groups with bullying experiences, and among transmasculine youth in particular (e.g., odds ratio of generalized anxiety = 8.36 (95% confidence interval, 6.59–10.6)). Bullying is associated with poorer mental health in all youth, but transgender youth, and especially transmasculine youth, may be in an even more vulnerable position for its implications. This suggests that there is a need for improving effective measures to decrease bullying in schools and to improve wellbeing of transgender youth
