    Opis:
    Objectives: For the purpose of evaluation of exhaled NO as an index of airway inflammation, we assessed changes in fractional exhaled NO (FeNO) across a work shift and its relationship with respiratory complaints. Material and Methods: Chronic and work-aggravated respiratory complaints were assessed using a questionnaire in 89 male textile workers. FeNO and spirometry were performed before and after a work shift and all the changes were registered. Results: A significant increase in FeNO after a work shift was observed. Post-shift FeNO was significantly higher among the subjects with chronic respiratory complaints. There was an obvious decrease in FVC, and FEV₁ after a work shift; however, we couldn’t find a significant relationship between changes in respiratory parameters and concentration of inhalable dusts. Conclusions: FeNO increase after a work shift along with pulmonary function decrement and higher post-shift FeNO among subjects with respiratory complaints makes across-shift FeNO a non-invasive test for assessment of airway hyper-responsiveness in textile workers.

    Opis:
    ObjectivesAmbient air pollution is related to adverse respiratory effects. Because of a popular habit of recreational physical activity, the effects of exposure to increased levels of air pollution attract increasing attention. It remains unclear whether the allergy status has an impact on acute responses to air pollution exposure during brief exercise in young adults. The aim of the study was to determine if acute respiratory responses to ambient air pollution during physical exercise differ between young subjects with and without a history of upper respiratory allergy.Material and MethodsOverall, 41 young males with (N = 15, 36.6%) and without allergy (N = 26, 63.4%) performed short moderate-intensive cycle-ergometer sessions in winter air pollution exposure conditions. Associations were analyzed between environmental conditions and acute physiological changes in spirometry, fractioned exhaled nitric oxide (FeNO) levels, blood pressure and pulse oximetry.ResultsNo associations between air pollution concentrations and changes in forced vital capacity, forced expiratory volume in 1 s and the Tiffeneau index were found. In the subjects without allergy, the increased air pollution concentrations recorded during exercise were associated with a post-exercise increase/a smaller decrease in FeNO (SO2: Spearman’s ρ = 0.44, NOx: ρ = 0.51, and particulate matter [PM] levels – PM10: ρ = 0.51, PM2.5: ρ = 0.52). This effect was not observed in the subjects with allergy.ConclusionsUpper-respiratory allergy may be a modifying factor in human response to air pollution during exercise. Exposure to air pollution during brief moderate-intensive exercise did not have any acute negative impact on respiratory and cardiovascular function in young males. However, in the case of FeNO, subclinical post-exercise changes related to air pollution were observed in volunteers without allergy.

    Opis:
    Objectives: To investigate cardiorespiratory and inflammatory responses in male workers following exposure to welding fumes and airborne particles in actual workplace conditions. Materials and Methods: We measured blood leukocytes and their differential counts, platelet count, hemoglobin, sensitive C-reactive protein, fibrinogen, E-selectin, IL-(interleukin)1β, IL-6, IL-8, tumor necrosis factor alpha (TNF-α) and endothelin-1 in blood samples of twenty workers before and after their working day. We also studied peak expiratory flow (PEF), forced expiratory volume in one second (FEV₁), and exhaled nitric oxide (NO). We assessed heart rate variability (HRV) by obtaining 24-hour ambulatory electrocardiograms. Results: The total blood leukocytes and neutrophils increased after the work shift, whereas IL-1β and E-selectin decreased significantly. There were no tatistically significant changes in exhaled NO, FEV₁, PEF or HRV. Conclusion: Occupational exposure to welding fumes and particles caused a slight, acute inflammatory effect estimated based on the increased values of leukocytes and neutrophils in blood and a decrease in the interleukin 1β and E-selectin values, but no changes in the pulmonary function (exhaled NO, FEV₁, PEF) or HRV during the working day were observed.

    Opis:
    ObjectivesThe aim of the study was to evaluate the effects of repeated Finnish sauna baths on the concentrations of nitric oxide metabolites (NOx) and 3-nitrotyrosine in relation to pro-oxidative and antioxidative status in young males with different physical activity levels.Material and MethodsThe study was performed on healthy males (aged 20–25 years), representing the training (T, N = 10) and non-training groups (NT, N = 10). The protocol included a series of 10 sauna baths during 3 weeks. One bath consisted of three 15-min sessions, with 2 min recovery. Before the first and the 10th treatment, measurements of body composition, blood pressure, rectal temperature, and plasma concentrations of the total pro-oxidative and antioxidative status, 3-nitrotyrosine and NOx were performed.ResultsA significant increase in physiological parameters during sauna treatments, as well as a significant decrease in the total antioxidative status before the 10th bath, were observed in both groups. The series of sauna baths caused a significant increase in the total antioxidative status in the T group, and a decrease in the total oxidative status in the NT group. A significant decrease in 3-nitrotyrosine in both groups before the last treatment, and also in the T group after the last treatment, was noted. In both groups, a significant increase in NOx concentrations was observed after the first bath.ConclusionsA series of sauna baths contributes to the improvement in the prooxidative/antioxidative balance. The increased production of nitric oxide may lead to a better vascular relaxation and blood flow.
