Abstract
Environmental tobacco smoke (ETS), also known as secondhand smoking, contains human carcinogens associated with the development of many human diseases, including stroke, heart disease, leukemia, and lung cancer. Due to these adverse health effects, a sensitive and selective method is crucial for assessing the health impacts of ETS. While current methods to evaluate ETS exposure are either invasive or nonspecific and insensitive, in this study, we assessed the use of polyurethane foam face masks as a sampling medium to collect tobacco smoke-specific nicotine and nitrosamines for estimating personal exposure to ETS. This method was used in conjunction with tandem mass spectrometry coupled with isotope-dilution detection. After validation by comparison with the National Institute for Occupational Safety and Health standard method (NIOSH 2551) for nicotine, we quantitated ETS exposure in indoor and outdoor environments. The analysis shows the applicability of the method for monitoring nicotine down to ∼0.20 mg/m3 near an outdoor smoking hotspot and up to ∼5.2 mg/m3 in a room with burning cigarettes, all with a time resolution as short as 5 min. In comparison with the NIOSH method, the newly developed method is convenient, inexpensive, and does not require a personal sampling pump, thus can facilitate large-scale ETS exposure monitoring.

Abstract
Food allergies are a serious and rising public health concern. The potentially fatal consequence of food allergies makes managing them costly and anxiety-inducing. Rapid, on-site detection of allergenic ingredients in foods would greatly improve the health and quality of life of food allergy sufferers. This work demonstrates the feasibility of such a device using molecularly imprinted polymers (MIPs). The MIP sensor can detect allergenic soy markers at concentrations as low as 100 parts-per-billion, two orders of magnitude below clinically relevant thresholds, in both controlled and complex food samples. Sensor performance was qualitatively validated with commercially available soy allergen detection lateral flow devices (LFDs). The outcome of this application will address a long-standing analytical challenge to achieving fast, cost-effective, and scalable methods for direct detection of allergen tracers in food analysis.

Abstract
The tobacco epidemic is a public health threat that has taken a heavy toll of lives around the globe each year. Smoking affects both the smokers and those who are exposed to secondhand smoke, and careful tracking of exposure can be key to mitigating the potential hazards. For smokers, the variation of chemical compositions between commercial cigarettes has led to ambiguity in estimating the health risks, both for active smokers and others involuntarily exposed to tobacco smoke and byproducts. In this regard, sweat possesses an attractive opportunity to monitor smoke exposure due to sweat's abundance in biomolecules and its great accessibility. Here, we present a wearable sweat band to monitor nicotine, a prominent ingredient in cigarettes, as a viable way to quantitatively assess a wearer's exposure to smoking. Both smokers and normal subjects are tested to demonstrate the use of this device for smoke-related health monitoring. Our results exhibit confirmable and elevated nicotine levels in sweat for subjects inhaling cigarette smoke. This continuous and personalized sweat sensing device is leverage to monitor smoke pollution for a potentially broad population.

Abstract
A novel series of emissive o-carborane derivatives, which showed multicolor, highly solid-state emission (ΦF ≥ 43%) and ideal photochemical stability, were synthesized. Inspired by the powerful mammalian olfactory system, we, for the first time, successfully obtained a fluorescent sensor array, which exhibits superior detection capability for nicotine in the gaseous phase (down to 3 ppb). Furthermore, the sensor array can be extended to detect nicotine in aqueous solution at the nano-gram level (∼0.1 ng cm-2) and determine the smoke of cigarette and electronic cigarette.

MICROMACHINES 2019; 10:mi10040276.

Abstract
The objective of this research was to develop a surface-acoustic-wave (SAW) sensor of cigarette smoke to prevent tobacco hazards and to detect cigarette smoke in real time through the adsorption of an ambient tobacco marker. The SAW sensor was coated with oxidized hollow mesoporous carbon nanospheres (O-HMC) as a sensing material of a new type, which replaced a polymer. O-HMC were fabricated using nitric acid to form carboxyl groups on carbon frameworks. The modified conditions of O-HMC were analyzed with Scanning Electron Microscopy (SEM), Fourier transform infrared spectrometry (FTIR), and X-ray diffraction (XRD). The appropriately modified O-HMC are more sensitive than polyacrylic acid and hollow mesoporous carbon nanospheres (PAA-HMC), which is proven by normalization. This increases the sensitivity of a standard tobacco marker (3-ethenylpyridine, 3-EP) from 37.8 to 51.2 Hz/ppm and prevents the drawbacks of a polymer-based sensing material. On filtering particles above 1 μm and using tar to prevent tar adhesion, the SAW sensor detects cigarette smoke with sufficient sensitivity and satisfactory repeatability. Tests, showing satisfactory selectivity to the cigarette smoke marker (3-EP) with interfering gases CH4, CO, and CO2, show that CO and CO2 have a negligible role during the detection of cigarette smoke.

Abstract
OBJECTIVE To determine if low-cost air-quality monitors providing personalised feedback of household second-hand smoke (SHS) concentrations plus standard health service advice on SHS were more effective than standard advice in helping parents protect their child from SHS. DESIGN A randomised controlled trial of a personalised intervention delivered to disadvantaged mothers who were exposed to SHS at home. Changes in household concentrations of fine Particulate Matter (PM2.5) were the primary outcome. METHODS Air-quality monitors measured household PM2.5 concentrations over approximately 6 days at baseline and at one-month and six-months post-intervention. Data on smoking and smoking-rules were gathered. Participants were randomised to either Group A (standard health service advice on SHS) or Group B (standard advice plus personalised air-quality feedback). Group B participants received personalised air-quality feedback after the baseline measurement and at 1-month. Both groups received air-quality feedback at 6-months. RESULTS 120 mothers were recruited of whom 117 were randomised. Follow up was completed after 1-month in 102 and at 6-months in 78 participants. There was no statistically significant reduction in PM2.5 concentrations by either intervention type at 1-month or 6-months, nor significant differences between the two groups at 1-month (p = 0.76) and 6-month follow-up (p = 0.16). CONCLUSIONS Neither standard advice nor standard advice plus personalised air-quality feedback were effective in reducing PM2.5 concentrations in deprived households where smoking occurred. Finding ways of identifying homes where air-quality feedback can be a useful tool to change household smoking behaviour is important to ensure resources are targeted successfully.

Abstract
Introduction Forty percent of young children worldwide are exposed to the harmful effects of tobacco smoke, predominantly by parental smoking. Little is known about why parents regularly expose their children to these risks; perhaps parents underestimate the degree of exposure. Qualitative methods were used to investigate parental perceptions of tobacco smoke exposure. Methods Sixty-five in-depth interviews were conducted with parents of young children in smoking families in central Israel. Parents were asked to explain what "exposure to smoking" meant. Thematic analysis was performed, a conceptual model of perceptions was built, and misconceptions were identified. Results Parents reported that exposure occurs when smoke or smokers are visible, when smoke can be smelled, felt, or inhaled, or when it "reaches" an individual. Conversely, some believed that exposure does not occur in the absence of odor, visible smoke, or smokers or if smoking occurs outdoors or in indoor ventilated environments. Proximity in space and time affected perceptions of exposure; some parents believed that smoke does not spread far but dissipates rapidly. There was some uncertainty regarding whether or not exposure was occurring. Conclusions Awareness of child exposure to tobacco smoke among parents in this study was based on sensory perceptions in the context of the physical environment. The limited capacity of humans to perceive tobacco smoke can lead to misconceptions about exposure. In order to protect children, parents must be convinced that exposure can occur even in situations where they are unable to sense it. Implications Parents use sensory perceptions (sight, smell, and feel) in the context of the physical environment to assess whether or not their children are exposed to tobacco smoke. Because 85% of smoke is invisible and the sense of smell is unreliable, assessments based on sensory perceptions cannot provide accurate information about the presence of tobacco smoke. In order to protect children, parents must be convinced that exposure can occur even in situations where they are unable to sense it. The scientific information summarized here about exposure in common situations should be useful in persuading parents to protect their children. Clinical Trial Registration This study is registered as a Phase I study which is part of a larger research endeavor entitled: A program to protect young children from tobacco smoke exposure. Registration number: NCT01335178.

Abstract
BACKGROUND Tobacco smoke exposure (TSE) harms children, who are often "captive smokers" in their own homes. Project Zero Exposure is a parent-oriented, theory-based intervention designed to reduce child TSE. This paper reports on findings from the pilot study, which was conducted in Israel from 2013 to 2014. METHODS The intervention consisted of motivational interviews, child biomarker and home air quality feedback, a Web site, a video, and self-help materials. The primary outcome was child TSE as measured by hair nicotine. Secondary outcome measures were air nicotine and particulate matter, parental reports of TSE, parental smoking behavior, and TSE child protection. A single-group pre- and posttest design was used. RESULTS Twenty-six of the 29 recruited families completed the study. The intervention was feasible to implement and acceptable to participants. Among the 17 children with reliable hair samples at baseline and follow-up, log hair nicotine dropped significantly after the intervention (P = .04), hair nicotine levels decreased in 64.7% of children, and reductions to levels of nonexposed children were observed in 35.3% of children. The number of cigarettes smoked by parents (P = .001) and parent-reported child TSE declined (P = .01). Logistical issues arose with measurement of all objective measures, including air nicotine, which did not decline; home air particulate matter; and hair nicotine. CONCLUSIONS A program based on motivational interviewing and demonstrating TSE and contamination to parents in a concrete and easily understandable way is a promising approach to protect children from TSE. Further research is needed to enhance current methods of measurement and assess promising interventions.

Abstract
This study aims to examine the prevalence of exposure to environmental tobacco smoke (ETS) in homes among socially-disadvantaged populations in Poland, along with the prevalence and correlates of voluntary implementation of smoke-free home rules. Data concerning 1617 respondents from a cross-sectional study completed in the Piotrkowski District were used, which was part of the "Reducing Social Inequalities in Health" program. Overall, 19.4% of the respondents declared exposure to ETS at home. In the non-smokers group, 15.5%, including 6.6% males and 18.3% females, were exposed to ETS in their place of residence (p < 0.0001). Complete smoke-free rules were adopted by 22.1% of the study participants. Two factors, smoker status and lack of ETS-associated health risk awareness, were found to be significantly associated with no adoption of total smoking bans at home. Socially-disadvantaged non-smokers, especially females from rural areas in Poland, still constitute a large population exposed to ETS in their homes-a challenge from the perspective of public health. Focused efforts are required to address social norms around exposing others to ETS.

AIMS We tested two aims: (1) the teachable moment (TM): whether second-hand smoke exposure (SHSe) feedback motivates cessation in parents of children with asthma versus parents of healthy children (HC); and (2) whether greater intervention intensity [enhanced-precaution adoption model (PAM)] produces greater cessation than a previously tested intervention (PAM). DESIGN AND INTERVENTIONS Aim 1: two home visits (asthma education or child wellness), and cessation induction using motivational interviewing and SHSe feedback. Aim 2: post-home-visits, parents with asthmatic children were randomized to PAM (n = 171; six asthma education calls) or enhanced-PAM (n = 170; six asthma education/smoking cessation calls + repeat SHSe feedback). SETTING Rhode Island, USA. PARTICIPANTS Parents of asthmatic (n = 341) or healthy (n = 219) children who did not have to want to quit smoking to enroll. MEASUREMENTS Measurements were given at baseline, 2, 4, 6 and 12 months. Abstinence was bioverified. Outcomes were 7-day and 30-day point prevalence abstinence (ppa) and SHSe (primary) and asthma morbidity (secondary). FINDINGS Aim 1: the TM was supported: parents of asthmatic children were more than twice as likely to achieve 30-day [odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.22-5.54] and 7-day ppa (OR = 2.26, 95% CI = 1.13-4.51) at 2 months (primary end-point) and have non-detectable levels of SHSe than HCs. Greater treatment intensity yielded stronger TM effects (OR = 3.60; 95% CI = 1.72-7.55). Aim 2: enhanced-PAM was more likely to achieve 30-day ppa at the primary end-point, 4 months (OR = 2.12, 95% CI 1.09-4.12) and improved asthma outcomes versus PAM. CONCLUSIONS Smoking cessation intervention (Motivational Interviewing plus biomarker feedback) appear to motivate smoking cessation more strongly among parents of asthmatic children than among parents of healthy children. Increased intervention intensity yields greater smoking cessation among parents of asthmatic children and better asthma outcomes.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:16043-59. [PMID: 26694440 PMCID: PMC4690974 DOI: 10.3390/ijerph121215038] [Citation(s) in RCA: 71] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/18/2015] [Revised: 12/03/2015] [Accepted: 12/09/2015] [Indexed: 12/16/2022]
Abstract
INTRODUCTION Smoke-free homes can help protect children from tobacco smoke exposure (TSE). The objective of this study was to conduct a meta-analysis to quantify effects of interventions on changes in tobacco smoke pollution in the home, as measured by air nicotine and particulate matter (PM). METHODS We searched MEDLINE, PubMed, Web of Science, PsycINFO, and Embase. We included controlled trials of interventions which aimed to help parents protect children from tobacco smoke exposure. Two reviewers identified relevant studies, and three reviewers extracted data. RESULTS Seven studies were identified. Interventions improved tobacco smoke air pollution in homes as assessed by nicotine or PM. (6 studies, N = 681, p = 0.02). Analyses of air nicotine and PM separately also showed some benefit (Air nicotine: 4 studies, N = 421, p = 0.08; PM: 3 studies, N = 340, p = 0.02). Despite improvements, tobacco smoke pollution was present in homes in all studies at follow-up. CONCLUSIONS Interventions designed to protect children from tobacco smoke are effective in reducing tobacco smoke pollution (as assessed by air nicotine or PM) in homes, but contamination remains. The persistence of significant pollution levels in homes after individual level intervention may signal the need for other population and regulatory measures to help reduce and eliminate childhood tobacco smoke exposure.

Feasibility of Measuring Tobacco Smoke Air Pollution in Homes: Report from a Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:15129-42. [PMID: 26633440 PMCID: PMC4690906 DOI: 10.3390/ijerph121214970] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2015] [Revised: 11/04/2015] [Accepted: 11/05/2015] [Indexed: 11/16/2022]
Abstract
Tobacco smoke air pollution (TSAP) measurement may persuade parents to adopt smoke-free homes and thereby reduce harm to children from tobacco smoke in the home. In a pilot study involving 29 smoking families, a Sidepak was used to continuously monitor home PM(2.5) during an 8-h period, Sidepak and/or Dylos monitors provided real-time feedback, and passive nicotine monitors were used to measure home air nicotine for one week. Feedback was provided to participants in the context of motivational interviews. Home PM(2.5) levels recorded by continuous monitoring were not well-accepted by participants because of the noise level. Also, graphs from continuous monitoring showed unexplained peaks, often associated with sources unrelated to indoor smoking, such as cooking, construction, or outdoor sources. This hampered delivery of a persuasive message about the relationship between home smoking and TSAP. By contrast, immediate real-time PM(2.5) feedback (with Sidepak or Dylos monitor) was feasible and provided unambiguous information; the Dylos had the additional advantages of being more economical and quieter. Air nicotine sampling was complicated by the time-lag for feedback and questions regarding shelf-life. Improvement in the science of TSAP measurement in the home environment is needed to encourage and help maintain smoke-free homes and protect vulnerable children. Recent advances in the use of mobile devices for real-time feedback are promising and warrant further development, as do accurate methods for real-time air nicotine air monitoring.

Abstract
The study of asthma and other complex diseases has proven to be a "moving target" for researchers due to its complex aetiology, difficulty in definition, and immeasurable environmental effects. A large number of studies regarding the contribution of both genetic and environmental factors often result in contradictory results, in part due to the highly heterogeneous nature of asthma. Recent literature has focused on the epigenetic signatures of asthma caused by environmental factors, highlighting the importance of environment. However, unlike the genetic techniques, environmental assessment still lacks accuracy. A plausible solution for this problem would be an individual-based environmental exposure assessment, relying on new technologies such as personal real-time environmental sensors. This could prove to enable the assessment of the whole environmental exposure-or exposome-matching in terms of precision the genome that is emphasized in most studies so far. In addition, the measurement of the whole array of biological molecules, in response to the environment action, could help understand the context of the disease. The current perspective comprises a beyond-genetics integrated vision of omics technology coupled with real-time environmental measures targeting to enhance our comprehension of the disease genesis.

Abstract
Much is known about the immediate and predictive antecedents of smoking lapse, which include situations (e.g., presence of other smokers), activities (e.g., alcohol consumption), and contexts (e.g., outside). This commentary suggests smartphone-based systems could be used to infer these predictive antecedents in real time and provide the smoker with just-in-time intervention. The smartphone of today is equipped with an array of sensors, including GPS, cameras, light sensors, barometers, accelerometers, and so forth, that provide information regarding physical location, human movement, ambient sounds, and visual imagery. We propose that libraries of algorithms to infer these antecedents can be developed and then incorporated into diverse mobile research and personalized treatment applications. While a number of challenges to the development and implementation of such applications are recognized, our field benefits from a database of known antecedents to a problem behavior, and further research and development in this exciting area are warranted.
