Vapor, Dust, and Smoke Exposure in Relation to Adult-Onset Asthma and Chronic Respiratory Symptoms

SUMMARY In the recent years the exposure to environmental tobacco smoke (ETS) has been an important public health hazard, especially in Serbia, a country with too many smokers. A common component of tobacco smoke is particulate matter less than 10μm in aerodynamic diameter (PM10), which is considered to be the most dangerous air pollutant for health. The aim of this paper was to investigate the association between respiratory symptoms and illnesses in schoolchildren in relation to their environmental tobacco smoke exposure. We conducted an epidemiological study that included 708 participants (49.15 % male) aged 11-14 years from Niš, Serbia. The children were surveyed by original structured questionnaire, based on the instrument developed for similar investigations. Data about the prevalence of respiratory symptoms in the last 12-month period of life and lifetime prevalence of respiratory illnesses were obtained. The questionnaire also included items about other indoor environmental determinants. Tobacco smoke was the most prevalent source of indoor air pollution at children’s home (60.73%). We found a significant association between ETS exposure and increased prevalence of dyspnea, wheezing, bronchitis and asthma among children. It is necessary to inform parents in Serbia on the health effects of ETS exposure during childhood and to encourage them to change smoking habits in order to protect their children from ETS exposure at home.

Abstract Background: Asthma is a common comorbid condition in patients with sickle cell disease. It has been well reported that patients with sickle cell and asthma have increased risk of morbidity and mortality, especially in regards to acute chest syndrome. Limited research, however, has been done to establish the role of asthma in vaso-occlusive crisis. Prior work by this group assessed the hypothesis that patients with sickle cell disease and comorbid asthma have increased severity and frequency of vaso-occlusive crisis secondary to increased impairment in oxygen exchange and associated sickling. A positive association was identified, providing groundwork for additional study. Objectives: This study was designed to further identify and risk-stratify patients at increased likelihood of vaso-occlusive complications that would benefit from respiratory-driven interventions. This was proposed through more extensive evaluation of the association between a diagnosis of comorbid asthma and frequency and severity of sickle cell vaso-occlusive crisis in addition to other potential indicators of risk, including passive smoke exposure and pulmonary function testing results. Design/Method: Following development and updating of a comprehensive institutional database, patients were identified with sickle cell disease and comorbid asthma ages 6 to 12 years of age. An additional subset of patients was identified as phenotypic and age-matched controls. Rates of emergency department visits and hospitalizations, frequency of vaso-occlusive crises, association with respiratory symptoms, smoke exposure status, pulmonary function test results, and use of asthma controller medications were retrospectively analyzed over a 5-year period. Data collection and interpretation were accompanied by review of existing literature. Results: Patients with sickle cell disease and comorbid asthma had a statistically significant greater number of presentations for pain over the study period in addition to presentations for acute chest and respiratory symptoms. Analysis of symptom chronology did not show a definitive relationship between onset of respiratory symptoms and subsequent development of pain symptoms. Smoke exposure status was evaluated as a possible compounding factor. A statistically significant association between use of asthma controller medication and patients presenting with pain was identified (p <0.01), although pulmonary function test results indicated that not all patients with a clinical diagnosis of asthma met objective criteria. Conclusion: Asthma management may have a role in the treatment of sickle cell vaso-occlusive crisis as evidenced by more frequent pain presentations in patients with asthma as well as a correlation in those patients on controller therapy. Results of pulmonary function testing indicated that not all patients met criteria for an objective diagnosis of asthma, suggesting that there may be a different etiology for these patients' lung impairment. Despite this, pulmonary function testing may still provide insight into disease progression. Further study of the use of asthma management as adjuvant therapy for sickle cell patients is in progress with the intent to improve pain management and decrease hospital encounters and hospital length of stay.

Objectives. To evaluate the safety of moxa smoke, especially to provide quantitative information and details for the occupational prevention of acupuncturists. Methods. We combined the questionnaire-based cross-sectional survey and lung function testing-based historical retrospective cohort research to investigate the safety of moxa smoke exposure (MSE) among acupuncturists. A mathematical regression model was established to quantitatively evaluate the relationship between moxa smoke exposure and the respiratory health of the acupuncturist. The smoke exposure time of the acupuncturist and the prevalence of abnormal respiratory symptoms or diseases were also evaluated. Results. (1) The cross-sectional research showed that the incidence of expectoration (18.7%) and rhinitis (22.7%) was the most common respiratory symptom and disease after MSE. No statistical difference was found between smoke exposure time of the acupuncturist and the prevalence of abnormal respiratory symptoms or diseases, except the prevalence of rhinitis and shortness of breath (P<0.01). Regression model for the incidence of first three symptoms (expectoration, shortness of breath, and wheezing) from the cross-sectional survey indicated that the weight coefficients of factors associated with moxa smoke were lower than those of factors unrelated to moxa smoke, such as gender and personal history of respiratory diseases. (2) Historical retrospective cohort research showed that there was no significant difference in the % predicted PEF. No statistic difference was found between the exposed and nonexposed group in large airway function indexes (% predicted FEV1, % predicted FVC, and % predicted FEV1/FVC) and small airway function indexes (% predicted FEF25, % predicted FEF50, % predicted FEF75, and % predicted MMEF), either. Especially, the % predicted MVV among males (106.23 ± 2.92 vs. 95.56 ± 1.92, P<0.01 and % predicted VC among females (100.70 ± 1.59 vs. 95.91 ± 1.61, P<0.05) between the two groups had statistical significance, but did not cause pulmonary ventilation dysfunction. Conclusions. MSE has no significant effect on the respiratory health of acupuncturists.
