Pioglitazone, a PPARγ agonist, reduces nicotine craving in humans, with marginal effects on abuse potential.

Pharmacol Biochem Behav. 2017 Oct 08;:

Authors: Jones JD, Comer SD, Metz VE, Manubay JM, Mogali S, Ciccocioppo R, Martinez S, Mumtaz M, Bisaga A

Abstract
Possibly through their actions upon glia, peroxisome proliferator-activated receptor agonists (PPAR) have been shown to alter the abuse potential of addictive drugs in several preclinical models. The current study extends this research into the human laboratory as the first clinical study into the effects of the PPAR gamma agonist, pioglitazone, on the abuse potential of nicotine. Heavy smokers were recruited for this 3-week study. Upon admission, participants were randomized to either active (45mg, n=14) or placebo (0mg, n=13) PIO maintenance conditions for the duration of the study. After 5-7days of stabilization on a 7mg nicotine patch, participants began laboratory testing. On the 1st-4th test days, participants could self-administer cigarettes or receive money by making verbal choices for either option. On the 5th day, participants were administered 10 puffs of their usual brand of cigarette in the morning and later chose between smoking and money by making finger presses on a computer mouse in a progressive ratio self-administration task. Later on the 5th day participants also underwent a smoking cue exposure session. The 8th-11th test days were identical to the 1st-4th test days with the exception that during one of the test weeks de-nicotinized cigarettes were available, and during the other nicotinized cigarettes were available. Nicotinized cigarettes were always administered on the 5th and 12th days. On some measures PIO increased indicators of abuse potential, though this effect was typically not statistically significant. However, PIO did significantly reduce measures of craving.

Trends in point-of-sale tobacco marketing around college campuses:Opportunities for enhanced tobacco control efforts.

J Am Coll Health. 2017 Oct 11;:0

Authors: Wagoner KG, Sutfin EL, Song E, King JL, Egan KL, Reboussin B, Debinski B, Spangler J, Wolfson M

Abstract
OBJECTIVE: Colleges have implemented policies to limit tobacco use on-campus; however, the off-campus environment is often overlooked in tobacco control efforts. We assessed availability, marketing, and promotion of cigarettes, snus, and traditional smokeless tobacco (SLT) in a sample of communities surrounding 11 college campuses in North Carolina and Virginia.
PARTICIPANTS: Between January-March of 2011, 2012 and 2013, 481 tobacco-selling retailers, including convenience stores, pharmacies and supermarkets, located near campuses were assessed.
METHODS: Trained observers completed annual point-of-sale assessments.
RESULTS: The percentage of stores selling (81.4% to 58.6%; p<.0001) and advertising snus (80.1% to 53.11%; p<.0001) significantly decreased over time. Convenience stores increased promotions of cigarettes (65.4% to 72.8%; p = 0.04) and SLT (3.1% to 23.3%; p = 0.02).
CONCLUSIONS: Off-campus environments have abundant tobacco availability and marketing. Colleges should collaborate with state and local tobacco control advocates to address tobacco promotion near campuses to potentially decrease product appeal and access among young adults.

Social vulnerabilities as determinants of overweight in 2-, 4- and 6-year-old Spanish children.

Eur J Public Health. 2017 Aug 04;:

Authors: Iguacel I, Fernández-Alvira JM, Labayen I, Moreno LA, Samper MP, Rodríguez G, CALINA study

Abstract
Background: Differences in obesity prevalence among vulnerable groups exist in childhood but it remains unclear whether these differences may be partly determined by socioeconomic status (SES), parental body mass index (BMI) and early life risk factors. We aimed to explore (i) longitudinal associations between belonging to a minority group and being overweight/obese at age 2, 4 and 6 and (ii) associations between accumulation of social vulnerabilities and being overweight/obese at age 6.
Methods: In total, 1031 children (53.8% boys) were evaluated at birth and re-examined during a 6-year follow-up in a representative cohort of Aragon (Spain). Children from minority (vulnerable) groups included Spanish Roma/gypsies, Eastern Europeans, Latin Americans and Africans. Two more vulnerable groups were defined at baseline as children whose parents reported low occupation and education. Ethnicity, SES and parental BMI were collected via interviews. We used logistic mixed-effects models and adjusted for parental BMI, SES, mother's tobacco use, maternal weight gain, birth weight, infant weight gain and breastfeeding practices.
Results: Regardless of confounders, Roma/gypsy children (OR = 4.63;[1.69-12.70]95%CI) and with Latin American background (OR = 3.04;[1.59-5.82]95%CI) were more likely to be overweight/obese at age 6 compared with non-gypsy Spanish group. Children with three vulnerabilities (OR = 2.18;[1.31-3.64]95%CI) were more likely to be overweight/obese at age 6 compared with children with no vulnerabilities. No associations were found between belonging to a minority group and overweight/obesity in children under 6.
Conclusion: Interventions should target Roma/gypsy children, Latin American children and those who accumulate more vulnerabilities as they are at higher risk of being overweight/obese at age 6.

The association between tobacco smoking and atherosclerotic plaques in the carotid artery is partly mediated by cadmium exposure.

Am J Epidemiol. 2017 Sep 11;:

Authors: Andersson EM, Fagerberg B, Sallsten G, Borné Y, Hedblad B, Engström G, Barregard L

Abstract
Exposure to cadmium confers increased cardiovascular risk. Tobacco smoke contains cadmium, which, hypothetically, may mediate parts of the tobacco-associated risk of developing atherosclerotic plaques. Baseline data from the Swedish Malmö Diet and Cancer cohort (1991-1996) were used to test this hypothesis. Mediation analysis was used to examine associations between smoking and blood cadmium levels, and prevalence of ultrasound-assessed carotid atherosclerotic plaques. The total association with smoking status (never-smokers, two categories of ex-smokers, and current smokers) was split into direct and indirect association and the proportion mediated was estimated. The adjusted estimated plaque prevalence was ~27% among never-smokers. We identified both a direct and an indirect pathway between smoking and carotid plaques; the indirect association, through cadmium, was observed among current smokers and ex-smokers who had quit smoking less than 15 years ago. For current smokers, the prevalence ratio for plaque was 1.5, with 60%-65% of the association with smoking being mediated through cadmium. Recent ex-smokers had a prevalence ratio of 1.3, and 40%-45% was mediated through cadmium. Long-time ex-smokers had a prevalence ratio of 1.2, but none of the association was mediated through cadmium. In conclusion, about two thirds of the proatherosclerotic association with smoking was mediated by cadmium.

They're heating up: Internet search query trends reveal significant public interest in heat-not-burn tobacco products.

PLoS One. 2017;12(10):e0185735

Authors: Caputi TL, Leas E, Dredze M, Cohen JE, Ayers JW

Abstract
Heat-not-burn tobacco products, battery powered devices that heat leaf tobacco to approximately 500 degrees Fahrenheit to produce an inhalable aerosol, are being introduced in markets around the world. Japan, where manufacturers have marketed several heat-not-burn brands since 2014, has been the focal national test market, with the intention of developing global marketing strategies. We used Google search query data to estimate, for the first time, the scale and growth potential of heat-not-burn tobacco products. Average monthly searches for heat-not-burn products rose 1,426% (95%CI: 746,3574) between their first (2015) and second (2016) complete years on the market and an additional 100% (95%CI: 60, 173) between the products second (2016) and third years on the market (Jan-Sep 2017). There are now between 5.9 and 7.5 million heat-not-burn related Google searches in Japan each month based on September 2017 estimates. Moreover, forecasts relying on the historical trends suggest heat-not-burn searches will increase an additional 32% (95%CI: -4 to 79) during 2018, compared to current estimates for 2017 (Jan-Sep), with continued growth thereafter expected. Contrasting heat-not-burn's rise in Japan to electronic cigarettes' rise in the United States we find searches for heat-not-burn eclipsed electronic cigarette searches during April 2016. Moreover, the change in average monthly queries for heat-not-burn in Japan between 2015 and 2017 was 399 (95% CI: 184, 1490) times larger than the change in average monthly queries for electronic cigarettes in the Unites States over the same time period, increasing by 2,956% (95% CI: 1729, 7304) compared to only 7% (95% CI: 3,13). Our findings are a clarion call for tobacco control leaders to ready themselves as heat-not-burn tobacco products will likely garner substantial interest as they are introduced into new markets. Public health practitioners should expand heat-not-burn tobacco product surveillance, adjust existing tobacco control strategies to account for heat-not-burn tobacco products, and preemptively study the health risks/benefits, popular perceptions, and health messaging around heat-not-burn tobacco products.

The Prevalence and Characteristics of E-Cigarette Users in the U.S.

Int J Environ Res Public Health. 2017 Oct 11;14(10):

Authors: Levy DT, Yuan Z, Li Y

Abstract
Studies have examined the characteristics of individuals who use e-cigarettes, including sociodemographic and smoking characteristics, and the relationship of e-cigarette use to tobacco control policies. While most studies consider a subset of these characteristics with weak measures of regular e-cigarette use, this study uses a large, recent U.S. survey to simultaneously consider the association of each of these factors with different use measures. Data from the May 2014 Tobacco Use Supplement-Current Population Survey is supplemented with information on tobacco control policies. The prevalence of ever, current (at least 1 of the last 30 days), and regular (at least 20 of the last 30 days) e-cigarette use were 7.7%, 2.1% and 0.9%, implying that 27.0% of ever users were current users of which 45.3% were regular users. E-cigarette use varied by socio-demographic characteristics and by smoking status, and depended on the measure of use adopted. However, regardless of measures, e-cigarette use was higher among those smokers who smoked more cigarettes. The association with policies was generally weak, but we found more regular use by smokers in low tax and low tobacco control spending states. The results indicate that the user characteristics differ depending on the e-cigarette use measure. The measure of use should be carefully considered in analyzing how e-cigarette use affects cigarette use.

Prevalence and determinants of susceptibility to cigarette smoking among non-smoking senior secondary school students in Ilorin, North Central Nigeria.

Int J Adolesc Med Health. 2017 Oct 11;:

Authors: Babatunde LS, Babatunde OT, Oladeji SM, Ashipa T

Abstract
Background Globally, efforts are being made to control tobacco use. However, adolescents who are susceptible to cigarette smoking constitute a major challenge to control efforts. Defining the magnitude of susceptible adolescents and associated factors in any setting is critical to the development of measures that will successfully address this issue. This study estimated the prevalence and factors associated with susceptibility to cigarette smoking among non smoking students in Ilorin, North Central Nigeria. Methods A cross sectional study involving 2000 secondary school students selected via multistage sampling technique. Data was collected using a self administered questionnaire, while analysis was done using SPSS 16.0. Results Prevalence of susceptibility to cigarette smoking among non smoking respondents was 13.6% (14.5% among males and 11.4% among females, respectively). Factors associated with susceptibility to cigarette smoking were parental smoking habit [odds ratio (OR) = 4.43], having close friends who smoke (OR = 6.54), engagement in vocational training (OR = 1.39), exposure to environmental tobacco smoke at home (OR = 1.61), knowledge of harmful effects of tobacco (OR = 2.35) and perceptions of the effect of cigarette smoking such as enhancing attractive among boys (OR = 2.03), and causing weight gain among boys (OR = 2.39) and among girls (OR = 6.05). Conclusion The high prevalence of susceptibility to cigarette smoking among the non smoking students highlights the potential for future increase in prevalence of cigarette smoking in the setting. Efforts at controlling cigarette smoking will not be totally successful if susceptibility to cigarette smoking among adolescents is not addressed.

The Risk of Hypertension and Other Chronic Diseases: Comparing Smokeless Tobacco with Smoking.

Front Public Health. 2017;5:255

Authors: Anand A, Sk MIK

Abstract
BACKGROUND: In the past, studies have compared smokeless tobacco and non-tobacco users for the risk of various chronic diseases. The differences in the risk of chronic diseases between smokeless tobacco user and smokers have not been explored. The objective of this study is to estimate the risk of chronic diseases among smokeless tobacco users compared to smokers.
METHODS: The data were used from the Study on Global Ageing and Adult Health (SAGE) Wave-1, conducted in 2007-2008 in India. The study sample is the respondents who reported consuming any form of tobacco in last 1 month. The total sample size was 4,038 respondents. The odds ratio of chronic morbidities was estimated taking smokers as the reference category.
RESULTS: The odds ratios for (self-reported) diabetes, asthma, and hypertension were not significant for smokeless tobacco user compared to smoked tobacco users. The odds ratio of chronic lung diseases (CLDs) was significantly lower among smokeless tobacco users compared to smoked tobacco users. The odds ratio of hypertension (measured) combined with low education and belonging to lowest wealth quintiles were not significant for smokeless tobacco users compared to smoked tobacco users. Duration of the use of smokeless tobacco and quantity of use was found to have no significant relation with risk of chronic diseases as compared to smoking.
CONCLUSION: This study did not find the significantly higher risk of chronic morbidities except for CLD for smokeless tobacco users compared to smoked tobacco users. The study suggests that the use of any form of tobacco may have a similar risk of chronic diseases.

Prevalence and associated factors of active smoking among individuals living with hypertension and/or diabetes in Africa: a systematic review and meta-analysis protocol.

BMJ Open. 2017 Oct 10;7(10):e015444

Authors: Wafeu GS, Tankeu AT, Endomba FTA, Nansseu JR, Kaze AD, Bigna JJ, Noubiap JJ

Abstract
INTRODUCTION: Tobacco use significantly increases cardiovascular complications in people living with hypertension and/or diabetes. We aim to summarise data on the prevalence and factors associated with active smoking in these conditions in Africa.
METHOD AND ANALYSIS: We will search PubMed, Embase, Google Scholar and African Journals Online for relevant abstracts of studies on active smoking in individuals living with diabetes and/or hypertension published from 1 January 2000 to 31 December 2016, with no language restriction. Additionally, relevant unpublished papers and conference proceedings will be checked, as well as references of included articles. Two investigators will independently screen, select studies, extract data and assess the risk of bias in each study. Data will be analysed using Stata software (Stata V.14, Texas, USA). The study-specific estimates will be pooled through a random-effects meta-analysis model to obtain an overall summary estimate of the prevalence of smoking across studies. Also, we will assess factors associated to smoking. Heterogeneity of studies will be evaluated by the χ2 test on Cochrane's Q statistic. Funnel plots analysis and Egger's test will be done to detect publication bias. Results will be presented by geographic region (central, eastern, northern, southern and western Africa). A p value less than 0.05 will be considered significant for factors associated to smoking.
ETHICS AND DISSEMINATION: This study is based on published data, and therefore ethical approval is not a requirement. This systematic review and meta-analysis is expected to serve as a basis for designing cost-effective interventions to reduce and prevent smoking in patients with diabetes and/or hypertension, and as a guide for future research based on the remaining gaps. The final report of this study in the form of a scientific paper will be published in peer-reviewed journals. Findings will further be presented at conferences and submitted to relevant health authorities.

Plasmid DNA purification by zirconia magnetic nanocomposite.

Anal Biochem. 2017 Oct 07;:

Authors: Saraji M, Yousefi S, Talebi M

Abstract
A zirconia magnetic nanocomposite was prepared by a co-precipitation method in one step. The synthesized nanocomposite was characterized by scanning electron microscopy, energy-dispersive X-ray and Fourier transform infrared spectroscopy. The nanocomposite was applied for the adsorption/desorption of tobacco plant DNA (as a model). Experimental parameters controlling adsorption efficiency, including pH of binding solution, extraction time, the amount of nanocomposite and ionic strength, were optimized. To obtain high desorption efficiency, the effects of pH, the ionic strength of elution buffer and desorption time were investigated. The nanocomposite provided the adsorption capacity of 53.5 mg g(-1) for DNA. The adsorption and desorption efficiency of the sorbent was found to be greater than 98 and 81%, respectively. The zirconia magnetic nanocomposite was used for the purification of plasmid DNA (pDNA) from Escherichia coli cell culture. The yield and purity of pDNA obtained by the method were compared to those obtained by the phenol-chloroform solvent extraction and a commercial kit.
