The noninvasive biomarkers of respiratory impairment were assessed in 15 swine confinement (SC) workers and 9 respiratory healthy, nonsmoking volunteers (HV). Spirometry, fraction of exhaled nitric oxide (FeNO), and exhaled breath condensate (EBC) pH were assessed in SC workers after one working shift and one working week and in HV after 5-hour exposure in SC. Half of the respiratory symptoms (in 8 of 15 SC workers) were work-related. Basal FeNO values were 7.5 ppb higher in the SC workers compared with HV. In the SC workers, EBC pH increased for 0.17 at the end of a working week (P < 0.001). In HV, 5-hour exposure in SC induced 8% drop in forced expiratory flow at 25% of the pulmonary volume (FEF25) (P = 0.008), EBC pH drop for 0.10 units (P = 0.003), and FeNO drop by 1.8 ppb (P = 0.047). EBC pH was suggested as a biomarker of acute airway acidification in HV, whereas the SC workers showed signs of the "healthy worker effect."

The aim of the study was to assess the effectiveness of the specific design of a poisoning prevention intervention. This controlled before-after study followed Solomon design for educational interventions using two groups (the educational intervention group and the control group). Participants comprised parents of children attending kindergartens under the jurisdiction of the City of Zagreb and in the vicinity of Zagreb. The intervention group (N = 336) underwent an educational intervention during parents’ meetings comprising oral presentation by the Croatian Poison Control Centre (CPCC) and distribution of gift packages containing child-proof locks, flyers, and stickers with the CPCC contact number. After the intervention they more frequently started keeping the CPCC’s number by their telephone or in the list of important numbers than parents in the control group, and this association remained significant when tested by generalized estimating equations for binary outcomes, after the adjustment for parents’ characteristics (age, gender and educational level), and clustered by kindergartens (p < 0.001). This means parents acknowledged the CPCC as an adequate and accessible way for initial management of poisoning incidents.

Background/Objectives: There is currently no food propensity questionnaire (FPQ) developed specifically to address pesticide intake in the adolescent population. Therefore, the objective of our study was to design a specific FPQ with emphasis on fruit and vegetable consumption and dietary exposure to pyrethroids (PYR) and organophosphate (OP) insecticides and to test its reproducibility. Methods: The FPQ was designed for the purpose of this study primarily by identifying high-risk foods according to the EFSA annual reports on pesticide residues in food. In total, 99 parents/guardians of 10–12-year-old boys completed the first FPQ during May to June 2022 and again during October 2022 to January 2023. Results: For the whole questionnaire, comprising 111 questions covering presumed major sources of pesticides in a diet, the median Cohen’s weighted kappa was 0.607 (interquartile range, IQR 0.526–0.678, total range 0.275–0.864). Furthermore, similar good overall reproducibility was noted when we focused only on the presumed food sources of PYR and OP pesticides (54 questions; median kappa 0.624, IQR 0.535–0.695, total range 0.275–0.864). Best reproducibility was noted for tomatoes (fresh, in season), lettuces (generic), and pork lard. Median estimated fruit intake for 459 adolescents based on the FPQ was 262 g/day (IQR 176–376 g/day), and vegetable intake was 123 g/day (IQR 74—190 g/day). Conclusions: Due to its good reproducibility, this FPQ, which estimates PYR and OP pesticide exposure, represents a valuable tool for future epidemiological studies and public health surveillance that focus on pesticide residue exposure in specific populations.
