Maternal post-natal tobacco use and current parental tobacco use is associated with higher body mass index in children and adolescents: an internatio…
2015
Background: We investigated whether maternal smoking in the first year of life or any current parental smoking is associated with childhood or adolescent body mass index (BMI). Methods: Secondary analysis of data from a multi-centre, multi-country, cross-sectional study (ISAAC Phase Three). Parents/guardians of children aged 6-7 years completed questionnaires about their children's current height and weight, whether their mother smoked in the first year of the child's life and current smoking habits of both parents. Adolescents aged 13-14 years completed questionnaires about their height, weight and current parental smoking habits. A general linear mixed model was used to determine the asso…
Roflumilast N-oxide inhibits bronchial epithelial to mesenchymal transition induced by cigarette smoke in smokers with COPD.
2014
Abstract Background Epithelial to mesenchymal transition (EMT) is under discussion as a potential mechanism of small airway remodelling in COPD. In bronchial epithelium of COPD and smokers markers of EMT were described. In vitro, EMT may be reproduced by exposing well-differentiated human bronchial epithelial cells (WD-HBEC) to cigarette smoke extract (CSE). EMT may be mitigated by an increase in cellular cAMP. Objective This study explored the effects of roflumilast N-oxide, a PDE4 inhibitor on CSE-induced EMT in WD-HBEC and in primary bronchial epithelial cells from smokers and COPD in vitro. Methods WD-HBEC from normal donors were stimulated with CSE (2.5%) for 72 h in presence of roflum…
Patterns on Work-Related Stress and Tobacco Consumption in City Bus Drivers
2018
Work-related stress and addictive behaviors have been described by several empirical studies as potential impairers for the health, welfare, and safety of workers. With this study, we aimed at describing the relationship between two work stress (Job Strain and Effort-Reward Imbalance) and tobacco consumption indicators among city bus drivers, and their association with traffic incidents registered by drivers along the last 2 years. For this cross-sectional study, the sample included 222 Colombian city bus drivers with a mean age of 41.4 years and driving experience of 18.63 years. A four-section questionnaire was used, and it was composed of individual (professional/demographic) information…
