BACKGROUND Youth smoking trends among Latin American countries, including Mexico, are on the rise. Notably, although the high prevalence of smoking in teens has been well documented in the literature, few studies have evaluated the impact of smoking and secondhand smoke (SHS) exposure on their respiratory system. OBJECTIVE To investigate the effects of smoking and SHS exposure on the respirat...

BACKGROUND The association between secondhand smoke (SHS) and risk of peripheral arterial disease (PAD) and stroke remains uncertain. METHODS AND RESULTS We examined the relationship between SHS and cardiovascular diseases, particularly PAD and stroke, in Chinese women who never smoked from a population-based cross-sectional study in Beijing, China. SHS exposure was defined as exposure to ano...

BACKGROUND Numerous studies have concluded that secondhand smoke (SHS) is harmful to non-smokers but controversy persists regarding its effects on smokers. The impact of SHS exposure on the acute respiratory health of current active smokers was examined using a cross sectional design. METHODS 9923 uniformed staff in the Hong Kong Police Force completed a standardised questionnaire on current ...

PURPOSE The aim of this research is to estimate lifetime costs and health consequences for Korean adult women who were exposed to secondhand smoke (SHS) at home. METHODS A Markov model was developed to project the lifetime healthcare costs and health outcomes of a hypothetical cohort of Korean women who are 40 years old and were married to current smokers. The Korean epidemiological data were...

OBJECTIVE To determine the prevalence, correlates and changes in secondhand smoke (SHS) exposure over the period after comprehensive smoke-free policy implementation in two Latin American countries. METHODS Data were analysed from population-based representative samples of adult smokers and recent quitters from the 2008 and 2010 waves of the International Tobacco Control Policy Evaluation Sur...

BACKGROUND Few studies have evaluated the association between secondhand smoke (SHS) and subclinical cardiovascular disease among ethnically diverse populations. This study assesses the impact of SHS on inflammation and atherosclerosis (carotid intima-media thickness, coronary artery calcification, and peripheral arterial disease). METHODS AND RESULTS We examined 5032 nonsmoking adults aged 4...

Stochastic hybrid systems (SHS) have attracted a lot of research interests in recent years. In this paper, we review some of the recent applications of SHS to biological systems modeling and analysis. Due to the nature of molecular interactions, many biological processes can be conveniently described as a mixture of continuous and discrete phenomena employing SHS models. With the advancement of...

The soft-and-hard surface (SHS) is employed to suppress the surface wave generated by a patch antenna integrated with high dielectric-constant LTCC multilayer packages. Two antenna structures are investigated to demonstrate the potential capability of the SHS in surface-wave suppression. The first is a stacked patch antenna on a large-size substrate. It is shown that using SHS can increase the ...

BACKGROUND Children's exposure to secondhand smoke (SHS) has been causally linked to a number of childhood morbidities and mortalities. Over 50% of UK children whose parents are smokers are regularly exposed to SHS at home. No previous review has identified the factors associated with children's SHS exposure in the home. AIM To identify by systematic review, the factors which are associated w...

This commentary is written to accompany a special research topic, Second Hand Smoke and COPD: lessons from animal studies, hosted by Frontiers in Respiratory Physiology. Model systems allow researchers to study disease, to tease out cause and effect and mechanisms of action, and to conduct the preliminary studies of the safety and efficacy of treatments. The underlying objective of the research...
