- CO2 concentration in day care centres is related to weezing in attending childrenPublication . Carreiro-Martins, Pedro; Viegas, João; Papoila, Ana Luísa; Aelenei, Daniel; Caires, Iolanda; Araújo-Martins, José; Gaspar-Marques, João; Cano, Maria Manuela; Mendes, Ana Sofia; Virella, Daniel; Rosado-Pinto, José; Leiria-Pinto, Paula; Annesi-Maesano, Isabella; Neuparth, NunoPoor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a proportional stratified random sampling. In phase II, 3 months later, 19 DCCs were further reassessed after cluster analysis for the greatest difference comparison. In both phases, children’s respiratory health was assessed by ISAAC-derived questionnaires. Indoor CO2 concentrations and buildingcharacteristics of the DCC were evaluated in both phases, using complementary methods. Mixed effect models were used to analyze the data. In phase I, which included 3,186 children (mean age 3.1±1.5 years), indoor CO2 concentration in the DCC rooms was associated with reported wheezing in the past 12months (27.5 %) (adjusted odds ratio (OR) for each increase of 200 ppm 1.04, 95 % CI 1:01 to 1:07). In phase II, the association in the subsample of 1,196 children seen in 19 out of the initial 45 DCCs was not significant (adjusted OR 1.02, 95 % CI 0.96 to 1.08). Indoor CO2 concentration was inversely associated with the practices of opening windows and internal doors and with higher wind velocity. A positive trend was observed between CO2 and prevalence of reported asthma (4.7 %). Conclusion: Improved ventilation is needed to achieve a healthier indoor environment in DCC.
- Effect of indoor air quality of day care centers in children with different predisposition for asthmaPublication . Carreiro-Martins, Pedro; Papoila, Ana Luisa; Caires, Iolanda; Azevedo, Susana; Cano, Maria Manuela; Virella, Daniel; Leiria-Pinto, Paula; Teixeira, João Paulo; Rosado-Pinto, José; Annesi Maesano, Isabella; Neuparth, NunoBACKGROUND: Scarce information is available about the relationships between indoor air quality (IAQ) at day care centers (DCC), the estimated predisposition for asthma and the actual wheezing susceptibility. METHODS: In the Phase II of ENVIRH study, 19 DCC were recruited after cluster analysis. Children were evaluated firstly using the ISAAC questionnaire and later by a follow up questionnaire about recent wheezing. A positive asthma predictive index (API) was considered as predisposition for asthma. Every DCC was audited for IAQ and monitored for chemical and biological contaminants. RESULTS: We included 1,191 children, with a median age of 43 (P25 -P75 : 25-58) months. Considering the overall sample, in the first questionnaire, associations were found between CO2 concentration (increments of 200 ppm) and diagnosis of asthma (OR: 1.10; 95% CI: 1.00 - 1.20). Each increment of 100 μg.m-3 of total volatile organic compounds (TVOC) and 1 μg of Der p1/g of dust were associated with wheezing in the previous 12 months (OR: 1.06; 95% CI: 1.01-1.11 and OR: 1.06; 95% CI: 0.99-1.12, respectively). In the follow-up questionnaire, TVOC were again associated with wheezing (OR: 1.05; 95% CI: 1.00-1.11). Children exposed to fungal concentration above the 75th percentile had also higher odds of wheezing at follow-up. TVOC were associated with wheezing in children with either negative or positive API. CONCLUSIONS: IAQ in DCC seems to be associated with wheezing, in children with and without predisposition for asthma. This article is protected by copyright. All rights reserved.
- Genomic epidemiology and resistome dynamics of species in a Portuguese Open Air Laboratory: the emergence of the FRI-8 carbapenemasePublication . Teixeira, Pedro; Ramos, Miguel; Rivière, Rani; Azevedo, Mónica; Ferreira, Mário; Cano, Maria Manuela; Vieira, Patrícia; Reis, Lígia; Matias, Rui; Rodrigues, João; Menezes, Carina; Rosado, Tânia; Sequeira, António; Moreira, Olga; Ruppitsch, Werner; Cabal-Rosel, Adriana; Mo, Solveig Sølverød; Dias, Elsa; Woegerbauer, Markus; Caniça, Manuela; Manageiro, VeraInterconnected reservoirs contribute to the global spread of antimicrobial resistance (AMR), including carbapenem- and colistin-resistant , highlighting the need for a One Health approach. We assessed the genomic epidemiology, diversity and AMR mechanisms of spp. across interconnected human, animal, plant, and environmental reservoirs in a Portuguese Open Air Laboratory. Over a one year monitoring period, samples from 12 different compartments were collected and processed using selective media to isolate spp., which were subjected to antibiotic susceptibility testing, whole-genome sequencing and subsequent analyses to identify AMR determinants, characterize plasmids and phylogenetic relationships. We established a collection of 61 isolates spanning nine species and 32 sequence types, including 16 novel ones, across nine compartments (river water, wastewater, soil, manure, feed, air, farmers, pigs, wild animals), reflecting the diversity and ubiquity of species. Core-genome analysis revealed eight genetic clusters, suggesting clonal transmission across compartments. In total, 29 antibiotic resistance genes were detected across all isolates. Notably, this is the first documentation of -harbouring in European environmental settings and the first to describe , and genes in Portugal. was detected in all isolates ( = 17), located on four different IncFII(Yp) plasmids, and in an isolate, flanked by IS3 family transposases. and the -harbouring isolate were resistant to carbapenems. A gene was identified in an isolate on an IncFII(pECLA) plasmid. These plasmids exhibited high sequence similarity with global counterparts, indicating potential for horizontal gene transfer. Other antimicrobial resistance genes included , , and . Our findings underscore the importance of as vectors for AMR and the critical role of environmental compartments in its dissemination, reinforcing the importance of adopting a One Health approach to fully understand AMR dynamics.
