    Given the high prevalence of young adult smoking, we examined (i) psychosocial factors and substance use among college students representing five smoking patterns and histories [non-smokers, quitters, native non-daily smokers (i.e. never daily smokers), converted non-daily smokers (i.e. former daily smokers) and daily smokers] and (ii) smoking…

    Objective: To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. Methods: We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. The level of PADL was assessed by the International Physical Activity Questionnaire and triaxial accelerometry, the device being used for seven days. The minimum level of PADL, in terms of quantity and intensity, was defined as 150 min/week of moderate to vigorous physical activity. Correlations between the studied variables were tested with Pearson's or Spearman's correlation coefficient, depending on the distribution of the variables. We used linear multiple regression in order to analyze the influence of PADL on the spirometric variables. The level of significance was set at 5%. Results: Evaluating all predictors, corrected for confounding factors, and using pulmonary function data as outcome variables, we found no significant associations between physical inactivity, as determined by accelerometry, and spirometric indices. The values for FVC were lower among the participants with arterial hypertension, and FEV1/FVC ratios were lower among those with diabetes mellitus. Obese participants and those with dyslipidemia presented with lower values for FVC and FEV1. Conclusions: Our results suggest that there is no consistent association between physical inactivity and pulmonary function in adult smokers. Smoking history should be given special attention in COPD prevention strategies, as should cardiovascular and metabolic comorbidities. PMID:27167434

    Despite the negative effects of smoking on lung functioning and overall health, smoking is more prevalent among individuals with asthma compared to those without asthma. The purpose of this study was to examine the predictive ability of asthma diagnosis in terms of smoking behavior and reasons for quitting. Participants were 251 regular daily smokers: 125 smokers with self-reported, physician-diagnosed asthma and 126 smokers without asthma. Asthma diagnosis significantly predicted age of regular smoking onset, number of quit attempts, and reasons for quitting related to self-control suggesting that smokers with asthma may have more difficulty quitting and unique reasons for quitting.

    This study investigates 1) the relationship between menthol cigarette smoking and obesity and 2) the association of body mass index with the nicotine metabolite ratio among menthol and non-menthol daily smokers aged 18–35 (n = 175). A brief survey on smoking and measures of height and weight, carbon monoxide, and saliva samples were collected from participants from May to December 2013 in Honolulu, Hawaii. Multiple regression was used to estimate differences in body mass index among menthol and non-menthol smokers and the association of menthol smoking with obesity. We calculated the log of the nicotine metabolite ratio to examine differences in the nicotine metabolite ratio among normal, overweight, and obese smokers. Sixty-eight percent of smokers used menthol cigarettes. Results showed that 62% of normal, 54% of overweight, and 91% of obese smokers used menthol cigarettes (p = .000). The mean body mass index was significantly higher among menthol compared with non-menthol smokers (29.4 versus 24.5, p = .000). After controlling for gender, marital status, educational attainment, employment status, and race/ethnicity, menthol smokers were more than 3 times as likely as non-menthol smokers to be obese (p = .04). The nicotine metabolite ratio was significantly lower for overweight menthol smokers compared with non-menthol smokers (.16 versus .26, p = .02) in the unadjusted model, but was not significant after adjusting for the covariates. Consistent with prior studies, our data show that menthol smokers are more likely to be obese compared with non-menthol smokers. Future studies are needed to determine how flavored tobacco products influence obesity among smokers. PMID:26844173

    Background China has the largest population of smokers in the world, yet the quit rate is low. We used data from the 2010 Global Adult Tobacco Survey China to identify factors influencing quit attempts among male Chinese daily smokers. Methods The study sample included 3303 male daily smokers. To determine the factors that were significantly associated with making a quit attempt, we conducted logistic regression analyses. In addition, mediation anal yses were carried out to investigate how the intermediate association among demographics (age, education, urbanicity) and smoking related variables affected making a quit attempt. Results An estimated 11.0% of male daily smokers tried to quit smoking in the 12 months prior to the survey. Logistic regression analysis indicated that younger age (15–24 years), being advised to quit by a health care provider (HCP) in the past 12 months, lower cigarette cost per pack, monthly or less frequent exposure to smoking at home, and awareness of the harms of tobacco use were significantly associated with making a quit attempt. Additional mediation analyses showed that having knowledge of the harm of tobacco, exposure to smoking at home, and having been advised to quit by an HCP were mediators of making a quit attempt for other independent variables. Conclusion Evidence-based tobacco control measures such as conducting educational campaigns on the harms of tobacco use, establishing smoke-free policies at home, and integrating tobacco cessation advice into primary health care services can increase quit attempts and reduce smoking among male Chinese daily smokers.

    Intermittent smokers (ITS) - who smoke less than daily - comprise an increasing proportion of adult smokers. Their smoking patterns challenge theoretical models of smoking motivation, which emphasize regular and frequent smoking to maintain nicotine levels and avoid withdrawal, but yet have gone largely unexamined. We characterized smoking patterns among 212 ITS (smoking 4-27 days per month) compared to 194 daily smokers (DS; smoking 5-30 cigarettes daily) who monitored situational antecedents of smoking using ecological momentary assessment. Subjects recorded each cigarette on an electronic diary, and situational variables were assessed in a random subset (n=21,539 smoking episodes); parallel assessments were obtained by beeping subjects at random when they were not smoking (n=26,930 non-smoking occasions). Compared to DS, ITS' smoking was more strongly associated with being away from home, being in a bar, drinking alcohol, socializing, being with friends and acquaintances, and when others were smoking. Mood had only modest effects in either group. DS' and ITS' smoking were substantially and equally suppressed by smoking restrictions, although ITS more often cited self-imposed restrictions. ITS' smoking was consistently more associated with environmental cues and contexts, especially those associated with positive or "indulgent" smoking situations. Stimulus control may be an important influence in maintaining smoking and making quitting difficult among ITS.

    Introduction Impulsivity is a multi-dimensional construct that is robustly related to cigarette smoking. While underlying factors that account for this relation are not well understood, craving has been proposed as a central mechanism linking impulsivity to smoking. In order to further refine our understanding of associations between impulsivity and cigarette craving, the current study examined the association between impulsivity and tonic and cue-elicited craving among a sample of adolescent smokers. We expected trait impulsivity would be positively associated with both tonic and cue-elicited craving, and that this relationship would be stronger among daily vs. occasional smokers. Methods 106 smokers (ages 16–20) completed questionnaires and reported their cigarette craving prior to and immediately following presentation of each of three counterbalanced cue types: (a) in vivo smoking, (b) alcohol, and (c) neutral cue. Results Impulsivity was positively associated with tonic craving for daily smokers (β=.38; p=.005), but not occasional smokers (β=.01; p=.95), with a significant impulsivity x smoker group interaction (β=1.31; p=.03). Impulsivity was unrelated to craving following smoking or alcohol cue, regardless of smoker group (all p’s>.16). Conclusions Results suggest a moderated effect in which impulsivity is positively associated with tonic craving for daily smokers, but not occasional smokers. Tonic craving may serve as a mechanism linking impulsivity, smoking persistence, and nicotine dependence among daily smokers. PMID:25665916

    The role of inhalation behaviors as predictors of nicotine uptake was examined in the Pennsylvania Adult Smoking Study (2012-2014), a study of 332 adults whose cigarette smoking was measured in a naturalistic environment (e.g., at home) with portable handheld topography devices. Piecewise regression analyses showed that levels of salivary cotinine, trans-3'-hydroxycotinine, and total salivary nicotine metabolites (cotinine + trans-3'-hydroxycotinine) increased linearly up to a level of about 1 pack per day (20 cigarettes per day (CPD)) (P < 0.01). Total daily puff volume (TDPV; in mL) (P < 0.05) and total daily number of puffs (P < 0.05), but not other topographical measures, increased linearly with CPD up to a level of about 1 pack per day. The mean level of cotinine per cigarette did not change above 20 CPD and was 36% lower in heavy smokers (≥20 CPD) than in lighter smokers (<20 CPD) (15.6 ng/mL vs. 24.5 ng/mL, respectively; P < 0.01). Mediation models showed that TDPV accounted for 43%-63% of the association between CPD and nicotine metabolites for smokers of <20 CPD. TDPV was the best predictor of nicotine metabolite levels in light-to-moderate smokers (1-19 CPD). In contrast, neither CPD, total daily number of puffs, nor TDPV predicted nicotine metabolite levels above 20 CPD (up to 40 CPD). Finally, although light smokers are traditionally considered less dependent on nicotine, these findings suggest that they are exposed to more nicotine per cigarette than are heavy smokers due to more frequent, intensive puffing.

    Preliminary evidence, within both adults and adolescents, suggests that the intensity with which cigarettes are smoked (i.e., smoking topography) is predictive of success during a cessation attempt. These reports have also shown topography to be superior compared to other variables, such as cigarettes per day, in the prediction of abstinence. The possibility that gender may influence this predictive relationship has not been evaluated but may be clinically useful in tailoring gender-specific interventions. Within the context of a clinical trial for smoking cessation among women, adult daily smokers completed a laboratory session that included a 1-hour ad libitum smoking period in which measures of topography were collected (N=135). Participants were then randomized to active medication (nicotine patch vs. varenicline) and abstinence was monitored for 4weeks. Among all smoking topography measures and all abstinence outcomes, a moderate association was found between longer puff duration and greater puff volume and continued smoking during the active 4-week treatment phase, but only within the nicotine patch group. Based on the weak topography-abstinence relationship among female smokers found in the current study, future studies should focus on explicit gender comparisons to examine if these associations are specific to or more robust in male smokers.

Methods In fall 2005, a random sample of 4,100 students completed an online survey. Results 29% reported current smoking, of which 70% were nondaily smokers. Compared to daily smokers, nondaily smokers were younger, African American (compared to White), had mothers with higher education, belonged to Greek organizations, and attended private (vs. public) schools. Nondaily smokers were less likely to have used illicit drugs. Conclusions Nondaily and daily smokers differed on several demographic and contextual factors, but reported mostly similar health risk behaviors. PMID:22370259

    Active marijuana produces significant subjective, psychomotor, and physiological effects relative to inactive marijuana, yet demonstrating that these effects are dose-dependent has proven difficult. This within-subject, double-blind study was designed to develop a smoking procedure to obtain a marijuana dose-response function. In four outpatient laboratory sessions, daily marijuana smokers (N = 17 males, 1 female) smoked six 5-s puffs from 3 marijuana cigarettes (2 puffs/cigarette). The number of puffs from active (≥5.5% Δ⁹-tetrahydrocannabinol/THC) and inactive (0.0% THC) marijuana varied according to condition (0, 2, 4, or 6 active puffs); active puffs were always smoked before inactive puffs. Subjective, physiological, and performance effects were assessed prior to and at set time points after marijuana administration. Active marijuana dose-dependently increased heart rate and decreased marijuana craving, despite evidence (carbon monoxide expiration, weight of marijuana cigarettes post-smoking) that participants inhaled less of each active marijuana cigarette than inactive cigarettes. Subjective ratings of marijuana "strength," "high," "liking," "good effect," and "take again" were increased by active marijuana compared with inactive marijuana, but these effects were not dose-dependent. Active marijuana also produced modest, non-dose-dependent deficits in attention, psychomotor function, and recall relative to the inactive condition. In summary, although changes in inhalation patterns as a function of marijuana strength likely minimized the difference between dose conditions, dose-dependent differences in marijuana's cardiovascular effects and ratings of craving were observed, whereas subjective ratings of marijuana effects did not significantly vary as a function of dose.

    Previous research has not compared implicit affective responses to smoking-related stimuli in occasional (i.e., those who smoke less than one cigarette per day) and daily smokers (i.e., those who smoke at least once per day). In addition to assessing their motivations for smoking, implicit affective responses were measured using the Affect Misattribution Procedure (AMP) in occasional (n=19) and daily smokers (n=34) to smoking-related and neutral cues. Half of the cues depicted a human interacting with an object (i.e., active), whereas the remaining cues depicted objects alone (i.e., inactive). Results indicated that for the active cues, daily smokers responded more positively to smoking-related than to neutral cues, whereas occasional smokers showed no difference in their implicit responses. In addition to smoking frequency, relative differences in implicit responses to active cues were related to cognitive enhancement motivation. For inactive cues, implicit responses were related to cognitive enhancement as well as reinforcement. Because daily smokers have more positive implicit responses to active smoking-related cues than occasional smokers, these cues may play an important role in maintaining smoking behavior in daily smokers.

    Under-reporting tobacco consumption is common, although there is lack of evidence whether under-reporting is associated with health risk perception. In this study, smoking topography from 110 smokers was recorded over 24 hours, aiming to capture a representative average of smoking behaviour. Participants significantly under-reported the duration of secondary exposure, and there was a significant interaction between self-report distortion type and risk perception. Analysis showed that smokers under-reporting puff number declared perceiving significantly less susceptibility to acquiring airway diseases, which is correlating significantly with the level of under-reporting. The present findings may suggest that under-reporting smoking behaviour has psychological functions beyond achieving social desirability.

Methods The authors examined nondaily versus daily smoking in relation to use of and interest in cessation strategies using an online survey. Results Nondaily (65.8%) versus daily smokers (34.3%) were more likely to have made a quit attempt (p = .01) but less likely to have used any assistance (p < .001). Nondaily smokers were less interested in pharmacotherapy and traditional behavioral interventions; however, there was no difference in interest in technology-based interventions among nondaily versus daily smokers. Controlling for covariates, there were no significant differences in interest in traditional or technology-based behavioral interventions. Higher motivation, lower confidence, and depressive symptomatology were related to interest in each intervention. Smoking for social reasons was related to interest in technology-based interventions. Conclusions Different intervention strategies may be appropriate for nondaily and daily smokers. PMID:22420696

    Background Non-daily smoking and heavy alcohol use are prevalent behaviors among young adults, with non-daily smoking occurring primarily in the context of alcohol use. Although the relationship between drinking and daily smoking has been well characterized in young adults, few epidemiological investigations have investigated the association between non-daily smoking and drinking behavior. Methods We examined Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; Grant et al., 2003; n=43,093). Young adults (age 18-25; n=5,838) were stratified on current smoking behavior (daily, non-daily, and non-smokers in the past 12 months) and differences in weekly quantity of alcohol use, frequency of alcohol use, frequency of binge drinking behavior, rates of NIAAA-defined hazardous drinking, and rates of DSM-IV alcohol diagnoses were investigated. College student status was examined. Results 25% were current smokers and 7% were smoking on a non-daily basis. 71% were current drinkers, 39% reported binge drinking at least once a month, 41% met criteria for hazardous drinking, and 18% had alcohol use disorders. Across all measures of alcohol use there was a significant effect of smoking status, with daily smokers having greater alcohol use patterns, compared to non-daily smokers, with non-smokers consuming the least. Non-daily smokers were more likely to report any binge drinking in the past 12 months. However, daily smokers were more likely to report daily binge drinking. With regard to hazardous drinking and alcohol use disorders, non-daily smoking conferred the greatest risk, followed by daily smoking with non-smoking as the reference group. Multinomial logistic regression demonstrated the odds of being a hazardous drinker were 16 times greater (95% CI 9.46 — 26.48) in a non-daily smoker compared to a non-smoker, whereas the odds for a daily smoker were increased by 7-fold (95% CI 5.54 — 9.36). A similar pattern of results was demonstrated

    Introduction Smoking is known to augment sympathetic activity and may lead to increased arterial stiffness. Several studies have reported association of increased sympathetic activity and arterial stiffness to cardiovascular risks among smokers. Pulse Wave Velocity (PWV) of peripheral arteries, instead of aorta can be used as a non-invasive indicator of arterial stiffness. Aim To measure non-invasively, the autonomic functions and peripheral arterial stiffness in smokers, and to find out whether the aforementioned factors are modified by the level of physical activity in these smokers. Materials and Methods This cross-sectional analytical study was conducted in the Department of Physiology, HIMS, Dehradun, over a period of 12 months (2013-2014) on 100 adult males (20-40 years); 50 smokers and 50 non-smokers. The parameters analysed include relevant anthropometric and cardiovascular parameters, Pulse Wave Velocity (PWV), sustained Hand Grip Test (HGT) and Heart Rate Variability (HRV) domains. Data interpretation and analysis was carried out using SPSS 17.0. Comparison of the above mentioned parameters amongst groups was done with unpaired t-test. The relationship of pack-years & physical activity with vascular functions was assessed by Pearson’s correlation. Interaction of various grades of smoking and physical activity with Cardiovascular System (CVS) parameters was assessed by one-way ANOVA. Results Smokers had higher values of PWV (5.7±0.5m/s) as compared to non-smokers (4.8±0.4m/s) (p<0.001). ΔDBP during HGT was lower (7±3.18mmHg) among smokers as compared to non-smokers (19.4±3.5mmHg) (p<0.001). Smoking (pack-years) was positively related to PWV (r= .03) but showed a weak negative relationship with change in Diastolic Blood Pressure (ΔDBP) (r= -0.084, p=0.56) showing that, more the frequency of smoking, the more was arterial stiffening and the lesser was the sympathetic response to the HGT. The smokers had significantly higher sympathetic activity; Low

    Young adults are at risk for initiation of tobacco use and progression to tobacco dependence. Not every person who smokes cigarettes becomes tobacco dependent, however, and non-daily smoking is becoming more prevalent among those who use tobacco. It is likely that individual differences in psychosocial and behavioral factors influence risk for engaging in non-daily and daily cigarette smoking. The objective of this study was to investigate the associations between impulsivity and smoking status in young adults who vary in frequency of cigarette smoking. Young adult first-year college students between the ages of 18-24 (512) were classified to one of three groups: non-smokers, non-daily smokers, or daily smokers, and impulsivity was assessed using the UPPS-P (negative and positive urgency, lack of premeditation, lack of perseverance, sensation seeking). When all impulsivity dimensions were used simultaneously to predict smoking status, negative urgency predicted increased risk of membership in the daily smoking group and lack of premeditation predicted increased risk of membership in the non-daily smoking group. These results suggest that dimensions of impulsivity may contribute differentially to forms of smoking behavior in young adults.

    Background Few studies have compared nicotine dependence among menthol and non-menthol cigarette smokers in a multiethnic sample of young adult daily cigarette smokers. This study examines differences in nicotine dependence among menthol and non-menthol daily smokers and the associations of nicotine dependence with quitting behaviors among Native Hawaiian, Filipino, and White cigarette smokers aged 18–35. Methods Craigslist.org, newspaper advertisements, and peer-to-peer referrals were used to recruit daily smokers (n = 186) into a lab-based study. Nicotine dependence was assessed using the Fagerstrom Test of Nicotine Dependence (FTND), the Nicotine Dependence Syndrome Scale (NDSS), and the brief Wisconsin Inventory for Smoking Dependence Motives (WISDM). Multiple regression analyses were used to examine differences in nicotine dependence between menthol and non-menthol smokers and the relationship between each nicotine dependence scale with self-efficacy to quit, quit attempt in the past 12 months, and number of attempts. Results Menthol smokers were more likely to report difficulty refraining from smoking in places where forbidden (p = .04) and had higher scores on social/environmental goads subscale of the WISDM (p = . 0005). Two-way interaction models of the FTND and menthol status showed that menthol smokers with higher levels of dependence were more likely to have tried to quit smoking in the past 12 months (p = .02), but were less likely to have had multiple quit attempts (p =.01). Conclusions Components of the FTND and WISDM distinguish levels of dependence between menthol and non-menthol smokers. Higher FTND scores were associated with having a quit attempt, but fewer quit attempts among menthol smokers. PMID:25744873

    Non-daily smokers commonly smoke cigarettes following the consumption of alcohol, yet the reason(s) for this remains poorly understood. The present study examined the impact of alcohol consumption on responses in tobacco salient cues 49 male and 50 female non-daily smokers. After the administration of an alcohol, placebo, or control beverage, participants were exposed to series neutral video clips and tobacco smoking salient video clips, and their subjective states and heart rates were monitored. The timing of the exposure to the tobacco smoking clips was randomly determined to coincide with the timing of either the ascending limb or the descending limb of the blood alcohol concentration (BAC) curve of the alcohol beverage condition. The tobacco smoking clips were found to increase cigarette craving regardless of beverage condition or timing of exposure (p = .002). Alcohol consumption was associated with increased ratings of intoxication (p < .001), increased heart rate across participants (p < .001), and increased cigarette craving in female participants specifically (p = .017). Alcohol did not influence responses to the smoking videos. These results suggest that smoking salient cues and alcohol may impact cigarette craving in non-daily smokers through independent processes.

    Exposure to cigarette smoke among smokers is highly variable. This variability has been attributed to differences in smoking behavior as measured by smoking topography, as well as other behavioral and subjective aspects of smoking. The objective of this study was to determine the factors affecting smoke exposure as estimated by biomarkers of exposure to nicotine and carbon monoxide (CO). In a multi-center cross-sectional study of 3585 adult smokers and 1077 adult nonsmokers, exposure to nicotine and CO was estimated by 24h urinary excretion of nicotine and five of its metabolites and by blood carboxyhemoglobin, respectively. Number of cigarettes smoked per day (CPD) was determined from cigarette butts returned. Puffing parameters were determined through a CreSS® micro device and a 182-item adult smoker questionnaire (ASQ) was administered. The relationship between exposure and demographic factors, smoking machine measured tar yield and CPD was examined in a statistical model (Model A). Topography parameters were added to this model (Model B) which was further expanded (Model C) by adding selected questions from the ASQ identified by a data reduction process. In all the models, CPD was the most important and highest ranking factor determining daily exposure. Other statistically significant factors were number of years smoked, questions related to morning smoking, topography and tar yield categories. In conclusion, the models investigated in this analysis, explain about 30-40% of variability in exposure to nicotine and CO.

    Background Identifying novel ways to recruit smokers for treatment studies is important. In particular, certain subgroups of adult smokers, such as heavy-drinking smokers, are at increased risk for serious medical problems and are less likely to try quitting smoking, so drawing this hard-to-reach population into treatment is important for improving health outcomes. Objective This study examined the utility of Facebook advertisements to recruit smokers and heavy-drinking smokers for treatment research and evaluated smoking and alcohol use and current treatment goals among those who responded to the Web-based survey. Methods Using Facebook’s advertising program, 3 separate advertisements ran for 2 months targeting smokers who were thinking about quitting. Advertisements were shown to adult (at least 18 years of age), English-speaking Facebook users in the greater New Haven, Connecticut, area. Participants were invited to complete a Web-based survey to determine initial eligibility for a smoking cessation research study. Results Advertisements generated 1781 clicks and 272 valid, completed surveys in 2 months, with one advertisement generating the most interest. Facebook advertising was highly cost-effective, averaging $0.27 per click, $1.76 per completed survey, and $4.37 per participant meeting initial screening eligibility. On average, those who completed the Web-based survey were 36.8 (SD 10.4) years old, and 65.8% (179/272) were female. Advertisements were successful in reaching smokers; all respondents reported daily smoking (mean 16.2 [SD 7.0] cigarettes per day). The majority of smokers (254/272, 93.4%) were interested in changing their smoking behavior immediately. Many smokers (161/272, 59.2%) also reported heavy alcohol consumption at least once a month. Among smokers interested in reducing their alcohol use, more were heavy drinkers (45/56, 80.4%) compared to non-heavy drinkers (11/56, 19.6%; χ2[1,N=272]=13.0, P<.001).

    Without ongoing surveillance systems to assess tobacco product demand and exposure levels, many low and middle income countries monitor smoking via periodic cross-sectional surveys. In this article, we seek to update estimates for the prevalence of adult smoking in Colombia and contribute additional information useful for tobacco control initiatives. Data are from the 2003 Colombian National Study of Mental Health (NSMH). A national probability sample of 4,426 adults (age 18-65) was assessed via a computer-assisted interview. An estimated 49% of the adult population had smoked at least once in their lifetimes; one in three adults (31%) had smoked regularly. Nearly half of regular smokers had been able to quit (44%; 95% CI= 40-48). Several personal and smoking related characteristics were associated with failing to quit: being a younger age, employed as compared to being a homemaker, and a history of daily use. Quitters and non-quitters were equivalent with respect to sex, educational status, and age of smoking onset. In conclusion, our findings describe the characteristics of regular smokers in Colombia and identify subgroups of non-quitters that may help guide tobacco control activities. PMID:18006241

    To the best of our knowledge, there have been no apparent studies of the trends in serum cotinine levels among smokers. Data from National Health and Nutrition Examination Survey for the period 1999-2010 were used to evaluate trends for serum cotinine levels; average number of cigarettes smoked per day; and Cambridge filter method (CFM) tar and CFM nicotine levels by gender, race/ethnicity, and cigarette mentholation status. Regression models were fitted to evaluate the factors associated with serum cotinine levels. Serum cotinine levels increased over time for both males and females, non-Hispanic whites and others. CFM nicotine levels also rose over time for cigarettes smoked by both males and females and by both non-Hispanic whites and non-Hispanic blacks. Average number of cigarettes smoked per day decreased over time for females, non-Hispanic whites and non-Hispanic blacks. CFM tar levels fell only for Mexican Americans. Exposure to second hand smoke at home was found to be associated with more than 1 ng/ml increase in serum cotinine levels. This large study on a nationally representative sample of daily smokers suggested that increasing concentrations of CFM nicotine in cigarettes over time led to elevated serum cotinine levels even though the number of cigarettes smoked daily remained relatively constant.

    Cue-elicited reactivity is a significant factor in relapse during smoking quit attempts. Previous research has focused primarily on visual smoking cues, with very limited research examining reactivity to olfactory triggers. Twenty-six adult, non-treatment seeking, nicotine-dependent smokers were exposed to seven odorants during a cue-reactivity session measuring heart rate, skin conductance, and subjective craving. Cues included 2 cigarette odors (fresh tobacco and cigarette smoke), 2 odors previously identified as smoking-related (freshly mowed grass and coffee), 2 odors previously identified as unrelated to smoking (lavender and burned rubber), and 1 odorless control (propylene glycol). Pairwise comparisons demonstrated that subjective intensity of craving was significantly higher following exposure to the fresh tobacco odor compared to the odorless control (p<.01). A significant main effect for cue type on a physiological measure of arousal was also revealed, with a fresh tobacco odor-elicited significant increase in skin conductance level compared to the odorless control. No main effect of cue type on heart rate, however, was found (p=.25). The results of the present study indicate that cigarette odor is an effective olfactory cue that heightens both subjective craving and increases skin conductance in smokers. Future research is needed to evaluate whether avoidance of these odors, or extinction of responses to them, can reduce relapse risk during smoking quit attempts. PMID:25180553

  11. Harm perception among Swedish daily smokers regarding nicotine, NRT-products and Swedish Snus

    PubMed Central

    2010-01-01

    Background In Sweden NRT-products and Snus, are easily available and used as smoking cessation aids. However, most quit attempts are made without any cessation aids. The limited use of these products as cessation aids may be influenced by the way smokers perceive the harmfulness of NRT-products and Snus compared to smoking. The present study examines these perceptions and their association with perceptions of the harmfulness of nicotine itself. Methods The study is based on the Swedish part of a two-nation web-based survey of daily smokers in Sweden (n = 1016) and Norway (n = 1000). Questionnaire items addressed perceptions of NRT-products' and Snus' harmfulness and nicotine's part of the health risks of smoking. Data analyses included cross-tabulations and logistic regressions. Results A majority, 59% of the answers to the question about harmfulness of NRT-products, and 75% of the answers about harmfulness of Snus, were inconsistent with the scientific evidence by demonstrating exaggerated perceptions of harmfulness. The strongest predictor of consistent answers was the perception of the harmfulness of nicotine. There were also significant associations with own experience of successful use of the products in question. Overall the perceptions of the harmfulness of nicotine were considerably exaggerated. This pattern was more pronounced among women than men. Prevailing misperceptions may be related to the way that different tobacco and nicotine products are presented in the media and other publicly available information sources. Conclusions Public information about smoking and health should be expanded to include objective and unambiguous information regarding nicotine's part in the harmfulness of smoking and the harmfulness of different nicotine-containing products compared to smoking. This is essential in order to preclude that misperceptions regarding these matters could discourage smokers from adopting effective cessation practices with use of nicotine

    The present investigation evaluated the factor structure of the Distress Tolerance Scale (DTS; Simons and Gaher 2005) among a sample of 173 (54.9% males) daily cigarette smokers (M=16.64 cigarettes per day, SD=7.83). Comparison of a single higher-order model and a hierarchical multidimensional model was conducted using confirmatory factor analyses (CFA). In addition, evaluation of the internal consistency and convergent and discriminant validity of the better-fitting model was completed. CFA of the DTS indicated a single second-order factor of distress tolerance, and four lower-order factors including Tolerance, Appraisal, Absorption, and Regulation; each factor demonstrated acceptable levels of internal consistency. In addition, the DTS displayed good convergent and discriminant validity with theoretically relevant smoking and affect variables. Results are discussed in terms of explicating the latent structure of distress tolerance, as measured by the DTS, within the context of smoking research.

    Given that cannabis use is increasing in the United States, pharmacological treatment options to treat cannabis use disorder are needed. Opioid antagonists modulate cannabinoid effects and may offer a potential approach to reducing cannabis use. In this double-blind, placebo-controlled human laboratory study, we assessed the effects of naltrexone maintenance on the reinforcing, subjective, psychomotor, and cardiovascular effects of active and inactive cannabis. Nontreatment-seeking, daily cannabis smokers were randomized to receive naltrexone (50 mg: n=18 M and 5 F) or placebo (0 mg; n=26 M and 2 F) capsules for 16 days. Before, during, and after medication maintenance, participants completed 10 laboratory sessions over 4-6 weeks, assessing cannabis' behavioral and cardiovascular effects. Medication compliance was verified by observed capsule administration, plasma naltrexone, and urinary riboflavin. Relative to placebo, maintenance on naltrexone significantly reduced both active cannabis self-administration and its positive subjective effects ('good effect'). Participants in the placebo group had 7.6 times (95% CI: 1.1-51.8) the odds of self-administering active cannabis compared with the naltrexone group. This attenuation of reinforcing and positive subjective effects also influenced cannabis use in the natural ecology. Naltrexone had intrinsic effects: decreasing ratings of friendliness, food intake, and systolic blood pressure, and increasing spontaneous reports of stomach upset and headache, yet dropout rates were comparable between groups. In summary, we show for the first time that maintenance on naltrexone decreased cannabis self-administration and ratings of 'good effect' in nontreatment-seeking daily cannabis smokers. Clinical studies in patients motivated to reduce their cannabis use are warranted to evaluate naltrexone's efficacy as a treatment for cannabis use disorder.

    Tobacco use is disproportionately represented among both alcohol-use disorders (AUDs) and anxiety disorders (ANX) compared to the general population (Kalman et al., 2005). Despite this common overlap, little is known about how smokers with co-occurring AUD-ANX differ from their nonsmoking counterparts. Seventy-two patients participated in a larger clinical trial evaluating the efficacy of venlafaxine and cognitive-behavioral therapy for AUD-ANX. Differences between daily smokers (n = 23), chippers (n = 12) and nonsmokers (n = 37) with AUD-ANX were examined with respect to intensity and frequency of alcohol use, anxiety symptoms, depressed mood, and stress. Point prevalence of current daily smoking was 31.9%, which is considerably lower than traditionally reported in AUD studies. Consistent with predictions, daily smokers reported higher levels of alcohol dependence, average drinks per drinking occasion, and peak blood concentration levels in a day than nonsmokers during the 90 days prior to assessment. Chippers were nonsignificantly different from either smokers or nonsmokers. Smokers and nonsmokers did not differ with respect to percent heavy drinking days or emotional symptoms. PMID:18656314

    Smoking is one of the most prevalent dependence disorders. Previous studies have detected structural and functional deficits in smokers. However, few studies focused on the changes of resting state functional connectivity (RSFC) of the brain regions with structural deficits in young adult smokers. Twenty-six young adult smokers and 26 well-matched healthy non-smokers participated in our study. Voxel-based morphometry (VBM) and RSFC were employed to investigate the structural and functional changes in young adult smokers. Compared with healthy non-smokers, young smokers showed increased gray matter (GM) volume in the left putamen and decreased GM volume in the left anterior cingulate cortex (ACC). Moreover, GM volume in the left ACC has a negative correlation trend with pack-years and GM volume in the left putamen was positively correlated with pack-years. The left ACC and putamen with abnormal volumes were chosen as the regions of interest (ROIs) for the RSFC analysis. We found that smokers showed increased RSFC between the left ACC and right amygdala and between the left putamen and right anterior insula. We revealed structural and functional deficits within the frontostriatal circuits in young smokers, which may shed new insights into the neural mechanisms of smoking. PMID:27757078

    Although previous research has demonstrated that individuals with parents who smoke are more likely to become smokers and are less successful in smoking cessation efforts compared with those without a smoking parent, the reasons for this link have not been established. In the current study, implicit attentional bias to smoking-related cues was investigated in college-age smokers, based on models of addiction that suggest that attention to drug-related cues plays an important role in drug addiction. Sixty-one participants completed a dot-probe task to measure attentional bias to smoking-related and matched non-smoking-related control pictures. Results indicated that while those who reported smoking occasionally did not demonstrate an attentional bias, daily smokers who had a smoking parent showed more of an attentional bias to the smoking cues than those without a smoking parent, but only to cues that did not contain human content. In addition to parental influence, nicotine dependence explained a significant portion of the variance in the attentional bias for daily smokers. Implications for models of nicotine addiction and the development of smoking cessation programs are discussed.

    2015-01-01

    Active marijuana produces significant subjective, psychomotor, and physiological effects relative to inactive marijuana, yet demonstrating that these effects are dose-dependent has proven difficult. This within-subject, double-blind study was designed to develop a smoking procedure to obtain a marijuana dose–response function. In four outpatient laboratory sessions, daily marijuana smokers (N = 17 males, 1 female) smoked six 5-s puffs from 3 marijuana cigarettes (2 puffs/cigarette). The number of puffs from active (≥5.5% Δ9-tetrahydrocannabinol/THC) and inactive (0.0% THC) marijuana varied according to condition (0, 2, 4, or 6 active puffs); active puffs were always smoked before inactive puffs. Subjective, physiological, and performance effects were assessed prior to and at set time points after marijuana administration. Active marijuana dose-dependently increased heart rate and decreased marijuana craving, despite evidence (carbon monoxide expiration, weight of marijuana cigarettes post-smoking) that participants inhaled less of each active marijuana cigarette than inactive cigarettes. Subjective ratings of marijuana “strength,” “high,” “liking,” “good effect,” and “take again” were increased by active marijuana compared with inactive marijuana, but these effects were not dose-dependent. Active marijuana also produced modest, non-dose-dependent deficits in attention, psychomotor function, and recall relative to the inactive condition. In summary, although changes in inhalation patterns as a function of marijuana strength likely minimized the difference between dose conditions, dose-dependent differences in marijuana’s cardiovascular effects and ratings of craving were observed, whereas subjective ratings of marijuana effects did not significantly vary as a function of dose.

    Limited information from human studies indicates that dietary quercetin supplementation influences blood lipid profiles, glycemic response, and inflammatory status, collectively termed cardiometabolic risks. We tested the hypothesis that quercetin-rich supplementation, derived from onion peel extract, improves cardiometabolic risk components in healthy male smokers in a randomized, double blinded, placebo-controlled parallel design. Randomly assigned subjects were instructed to take either the placebo (n = 43) or 100 mg quercetin capsules each day (n = 49) for 10 weeks. Anthropometric parameters and blood pressure were measured, and blood lipids, glucose, interleukin-6, and soluble vascular cell adhesion molecule-1 (sVCAM-1) were determined at baseline and after 10 weeks of quercetin supplementation. Quercetin-rich supplementation significantly reduced serum concentrations of total cholesterol (P < 0.05) and LDL-cholesterol (P < 0.01), whereas these effects were not shown in the placebo group. Furthermore, significant increases were observed in serum concentrations of HDL-cholesterol both in the placebo (P < 0.005) and quercetin-rich supplementation group (P < 0.001); however, changes in HDL-cholesterol were significantly greater in subjects receiving quercetin-rich supplementation than the placebo. Both systolic (P < 0.05) and diastolic blood pressure (P < 0.01) decreased significantly in the quercetin-rich supplementation group. Glucose concentrations decreased significantly after 10 weeks of quercetin-rich supplementation (P < 0.05). In contrast, no effects of quercetin-rich supplementation were observed for the inflammatory markers-IL-6 and sVCAM-1. Daily quercetin-rich supplementation from onion peel extract improved blood lipid profiles, glucose, and blood pressure, suggesting a beneficial role for quercetin as a preventive measure against cardiovascular risk.

    Recent studies have demonstrated the therapeutic potential of cannabinoids to treat pain, yet none have compared the analgesic effectiveness of smoked marijuana to orally administered Δ(9)-tetrahydrocannabinol (THC; dronabinol). This randomized, placebo-controlled, double-dummy, double-blind study compared the magnitude and duration of analgesic effects of smoked marijuana and dronabinol under well-controlled conditions using a validated experimental model of pain. Healthy male (N=15) and female (N=15) daily marijuana smokers participated in this outpatient study comparing the analgesic, subjective, and physiological effects of marijuana (0.00, 1.98, or 3.56% THC) to dronabinol (0, 10, or 20 mg). Pain response was assessed using the cold-pressor test (CPT): participants immersed their left hand in cold water (4 °C), and the time to report pain (pain sensitivity) and withdraw the hand from the water (pain tolerance) were recorded. Subjective pain and drug effect ratings were also measured as well as cardiovascular effects. Compared with placebo, marijuana and dronabinol decreased pain sensitivity (3.56%; 20 mg), increased pain tolerance (1.98%; 20 mg), and decreased subjective ratings of pain intensity (1.98, 3.56%; 20 mg). The magnitude of peak change in pain sensitivity and tolerance did not differ between marijuana and dronabinol, although dronabinol produced analgesia that was of a longer duration. Marijuana (1.98, 3.56%) and dronabinol (20 mg) also increased abuse-related subjective ratings relative to placebo; these ratings were greater with marijuana. These data indicate that under controlled conditions, marijuana and dronabinol decreased pain, with dronabinol producing longer-lasting decreases in pain sensitivity and lower ratings of abuse-related subjective effects than marijuana.

  2. Prevalence and co-use of marijuana among young adult cigarette smokers: An anonymous online national survey

    2012-01-01

    Background There is elevated prevalence of marijuana use among young adults who use tobacco, but little is known about the extent of co-use generated from surveys conducted online. The purpose of the present study was to examine past-month marijuana use and the co-use of marijuana and tobacco in a convenience sample of young adult smokers with national US coverage. Methods Young adults age 18 to 25 who had smoked at least one cigarette in the past 30 days were recruited online between 4/1/09 and 12/31/10 to participate in an online survey on tobacco use. We examined past 30 day marijuana use, frequency of marijuana use, and proportion of days co-using tobacco and marijuana by demographic characteristics and daily smoking status. Results Of 3512 eligible and valid survey responses, 1808 (51.5%) smokers completed the survey. More than half (53%, n = 960) of the sample reported past-month marijuana use and reported a median use of 18 out of the past 30 days (interquartile range [IR] = 4, 30). Co-use of tobacco and marijuana occurred on nearly half (median = 45.5%; IR = 13.1, 90.3) of the days on which either substance was used and was more frequent among Caucasians, respondents living in the Northeast or in rural areas, in nonstudents versus students, and in daily versus nondaily smokers. Residence in a state with legalized medical marijuana was unrelated to co-use or even the prevalence of marijuana use in this sample. Age and household income also were unrelated to co-use of tobacco and marijuana. Conclusion These results indicate a higher prevalence of marijuana use and co-use of tobacco in young adult smokers than is reported in nationally representative surveys. Cessation treatments for young adult smokers should consider broadening intervention targets to include marijuana. PMID:23186143

    The present investigation sought to evaluate the unique explanatory relevance of pain-related anxiety in relation to negative and positive reinforcement smoking outcome expectancies among 135 (40.7% female; M(age) = 26.11, SD = 11.23) adult daily cigarette smokers. As predicted, pain-related anxiety was significantly related to greater expectancies that smoking will decrease negative affect, and lesser expectancies that smoking will result in positive outcomes. The observed effects were evident above and beyond the variance accounted for by gender, current level of non-specific bodily pain, daily cigarette use, relations with non-criterion outcome expectancies, and shared variance with anxiety sensitivity. Results suggest that there may be segments of the smoking population who are at relatively greater risk for certain expectancies for tobacco smoking by virtue of individual differences in pain-related anxiety.

    The present investigation sought to evaluate the unique explanatory relevance of pain-related anxiety in relation to negative and positive reinforcement smoking outcome expectancies among 135 (40.7% female; Mage = 26.11, SD = 11.23) adult daily cigarette smokers. As predicted, pain-related anxiety was significantly related to greater expectancies that smoking will decrease negative affect, and lesser expectancies that smoking will result in positive outcomes. The observed effects were evident above and beyond the variance accounted for by gender, current level of non-specific bodily pain, daily cigarette use, relations with non-criterion outcome expectancies, and shared variance with anxiety sensitivity. Results suggest that there may be segments of the smoking population who are at relatively greater risk for certain expectancies for tobacco smoking by virtue of individual differences in pain-related anxiety.

    The paper reports levels of 24-h urine nicotine and five of its major metabolites (expressed as nicotine-equivalents) and blood carboxyhaemoglobin as biomarkers of exposure to particulate- and gas-phase cigarette smoke, respectively, from an exploratory pilot study of adult smokers of 3.0-6.9 mg tar delivery (Federal Trade Commission (FTC) method) cigarettes. On multiple occasions over 6 weeks, blood high-sensitivity C-reactive protein (hs-CRP), fibrinogen, HDL- and LDL-cholesterol, and 24-h urine 8-epi-prostaglandin F2alpha (8-epi-PGF2alpha) and 11-dehydro-thromboxane B2 (11-dehydro-TxB2) were also evaluated as biomarkers of potential harm. All the biomarkers examined, except for LDL-cholesterol, discriminated with high sensitivity and specificity between adult smokers and non-smokers overall. Except for HDL-cholesterol, all biomarker medians were greater in adult smokers than in non-smokers: urine nicotine-equivalents 64.514 versus < 0.034 nmol mg-1 creatinine (p<0.001), carboxyhaemoglobin 4.0 versus 0.4% saturation (p<0.001), hs-CRP 0.27 versus 0.12 mg dl-1 (p=0.05), fibrinogen 292 versus 248 mg dl-1 (p<0.001), HDL-cholesterol 46 versus 53 mg dl-1 (p=0.003), LDL-cholesterol 119 versus 109 mg dl-1 (p=0.18), urine 8-epi-PGF2alpha 1935 versus 1034 pg mg-1 creatinine (p<0.001) and urine 11-dehydro-TxB2 973 versus 710 pg mg-1 creatinine (p<0.001). All the biomarkers of exposure and most of the biomarkers of potential harm showed no time of sampling (by visit week) effect.

    Few studies have investigated the complex interactions among the individual- and community-level social risk factors that underlie adolescents' smoking behaviors. This study investigated whether community-level adult daily smoking prevalence is associated with adolescents' smoking and whether it moderates the associations between perceived friends' smoking approval and smoking behavior and adolescents' own smoking. Self-reported data from 1,190 youths (50.3% female; 13-18 years old) in 50 midsized Californian cities were obtained through telephone interviews. Community characteristics were obtained from 2010 GeoLytics data. Community adult daily smoking prevalence was ascertained from telephone interviews with 8,918 adults conducted in the same 50 cities. Multilevel analyses, controlling for individual and city characteristics, were used to predict adolescents' past 12-month smoking from perceived friends' smoking approval and smoking behavior and from community adult daily smoking prevalence. Results showed that perceived friends' smoking approval and behavior were associated positively with adolescents' smoking, as was the community-level prevalence of adult daily smoking. Furthermore, the association between perceived friends' smoking behavior and adolescents' own smoking was moderated by the prevalence of adult daily smokers in the community. Specifically, the association was stronger in cities with higher prevalence of adult smokers. These results suggest that adult community norms that are more supportive of smoking may enhance the influence of friends' smoking behavior. Therefore, interventions designed to prevent or reduce youths' smoking should also focus on reducing smoking by adults.

    Objectives To estimate the associations of neighbourhood walkability (based on Geographic Information System (GIS)-derived measures of street connectivity, land use mix, and population density and the Walk Score) with self-reported utilitarian walking and accelerometer-assessed daily steps in Canadian adults. Design A cross-sectional analysis of data collected as part of the Canadian Health Measures Survey (2007–2009). Setting Home neighbourhoods (500 m polygonal street network buffers around the centroid of the participant's postal code) located in Atlantic Canada, Québec, Ontario, the Prairies and British Columbia. Participants 5605 individuals participated in the survey. 3727 adults (≥18 years) completed a computer-assisted interview and attended a mobile clinic assessment. Analyses were based on those who had complete exposure, outcome and covariate data (n=2949). Main exposure measures GIS-derived walkability (based on land use mix, street connectivity and population density); Walk Score. Main outcome measures Self-reported utilitarian walking; accelerometer-assessed daily steps. Results No important relationship was observed between neighbourhood walkability and daily steps. Participants who reported more utilitarian walking, however, accumulated more steps (<1 h/week: 6613 steps/day, 95% CI 6251 to 6975; 1 to 5 h/week: 6768 steps/day, 95% CI 6420 to 7117; ≥6 h/week: 7391 steps/day, 95% CI 6972 to 7811). There was a positive graded association between walkability and odds of walking ≥1 h/week for utilitarian purposes (eg, Q4 vs Q1 of GIS-derived walkability: OR=1.66, 95% CI 1.31 to 2.11; Q3 vs Q1: OR=1.41, 95% CI 1.14 to 1.76; Q2 vs Q1: OR=1.13, 95% CI 0.91 to 1.39) independent of age, sex, body mass index, married/common law status, annual household income, having children in the household, immigrant status, mood disorder, perceived health, ever smoker and season. Conclusions Contrary to expectations, living in more walkable Canadian

    2013-01-01

    Background Young adulthood is a critical transition period for the development of health behaviors. We present here the results of a randomized controlled trial of an online avatar-hosted personal health makeover program designed for young adult smokers. Methods We conducted a three-group randomized trial comparing delivery of general lifestyle content (Tx1), personally tailored health information (Tx2), and personally tailored health information plus online video–based peer coaching (Tx3) as part of a 6-week online health program. Participants were asked to set weekly goals around eating breakfast, exercise, alcohol use, and cigarette smoking. Eligibility criteria included age (18–30 years) and smoking status (any cigarette use in the previous 30 days). The primary outcome was self-reported 30-day abstinence measured 12 weeks postenrollment. Results Participant (n = 1698) characteristics were balanced across the groups (72% women, mean age 24, 26% nonwhite, 32% high school education or less, and 50% daily smokers). Considering intention to treat, 30-day smoking abstinence rates were statistically significantly higher in the intervention groups (Tx1 = 11%, Tx2 = 23%, Tx3 = 31%, P < .001). Participants in the intervention groups were also more likely to reduce their number of days spent on binge drinking and increase their number of days eating breakfast and exercising. Overall, intervention group participants were much more likely to make positive changes in at least three or four of the target behaviors (Tx1 = 19%, Tx2 = 39%, Tx3 = 41%, P < .001). Conclusions This online avatar-hosted personal health makeover “show” increased smoking abstinence and induced positive changes in multiple related health behaviors. Addition of the online video–based peer coaching further improved behavioral outcomes. PMID:24395994

    Background There are few studies that examine the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China. Objective The goal of this study is to estimate the conditional cigarette consumption price elasticity among adult urban smokers in China using individual level longitudinal survey data. We also examine the differential responses to cigarette price increases among groups with different income and/or educational levels. Methods Multivariate analyses using the general estimating equations (GEE) method were conducted to estimate the conditional cigarette demand price elasticity using data from the International Tobacco Control (ITC) China Survey, a longitudinal survey of adult smokers in seven cities in China. The first three waves of the ITC China Survey data were used in this analysis. Analyses based on subsample by education and income were conducted. Findings Our results show that overall conditional cigarette demand price elasticity ranges from −0.12 to −0.14, implying a 10% increase in cigarette price would result in a reduction in cigarette consumption among adult urban Chinese smokers by 1.2% to 1.4%. No differential responses to cigarette price increase were found across education levels. The price elasticity estimates do not differ between high income smokers and medium income smokers. However, cigarette consumption among low income smokers did not seem to decrease after a price increase, at least among those who continued to smoke. Conclusion Relative to many other low- and middle-income countries, cigarette consumption among Chinese adult smokers is not very sensitive to changes in cigarette prices. The total impact of cigarette price increase would be larger if its impact on smoking initiation and cessation, as well as the price-reducing behaviors such as brand switching and trading down, were taken into account.

    Introduction: While young adults have the highest prevalence of cigarette smoking of any adult age group, studies of tobacco and other substance use have reported challenges in recruiting this age group. The Internet may be a useful tool for reaching young adult smokers. The present study compared three Internet-based recruitment methods for young adult smokers to complete a survey about tobacco and other substance use: Craigslist advertisements, other Internet advertisements, and E-mail invitations through a survey sampling service. Methods: Recruitment campaigns invited young adults aged 18–25 years who had smoked at least one cigarette in the past 30 days to complete an online survey. Recruitment methods were compared across recruitment numbers, costeffectiveness, and demographic and smoking characteristics of recruited participants. Results: In 6 months, 920 people gave online consent to determine eligibility to complete the survey, of which 336 (36.5%) were eligible, and 201 (59.8%) completed the survey. While Internet advertisements yielded the largest proportion of recruited participants and completed surveys overall, Craigslist and sampling strategies were more successful at targeting young adult smokers who went on to complete the survey and were more costeffective. Participants differed in demographic and substance use characteristics across the three recruitment mechanisms. Discussion: We identified success at reaching young adults who have smoked cigarettes recently through the Internet, though costs, participant eligibility, proportion of completed surveys, and respondent characteristics differed among the three methods. A multipronged approach to Internet recruitment is most likely to generate a broad diverse sample of young adult smokers. PMID:20530194

    Background To inform consumers, U.S. Federal Courts have ordered the tobacco industry to disseminate “corrective statements” (CSs) about their deception regarding five topics: smoker health effects, nonsmoker health effects, cigarette addictiveness, design of cigarettes to increase addiction, and relative safety of light cigarettes. Purpose To determine how smokers from diverse backgrounds respond to the final, court-mandated wording of these CSs. Methods Data were analyzed from an online consumer panel of 1,404 adult smokers who evaluated one of five CS topics (n=280–281) by reporting novelty, relevance, anger at the industry, and motivation to quit because of the CS. Logistic and linear regression models assessed main and interactive effects of race/ethnicity, gender, education, and CS topic on these responses. Data were collected in January 2013 and analyzed in March 2013. Results Thirty percent to 54% of participants reported that each CS provided novel information, and novelty was associated with greater relevance, anger at the industry, and motivation to quit because of the message. African Americans and Latinos were more likely than non-Hispanic whites to report that CSs were novel, and they had stronger responses to CSs across all indicators. Compared to men, women reported that CSs were more relevant and motivated them to quit. Conclusions This study suggests that smokers would value and respond to CSs, particularly smokers from groups that suffer from tobacco–related health disparities. PMID:24746372

    Further understanding is needed of the functionalities and efficiency of social media for health intervention research recruitment. Facebook was examined as a mechanism to recruit young adults for a smoking cessation intervention. An ad campaign targeting young adult smokers tested specific messaging based on market theory and successful strategies used to recruit smokers in previous clinical trials (i.e. informative, call to action, scarcity, social norms), previously successful ads, and general messaging. Images were selected to target smokers (e.g., lit cigarette), appeal to the target age, vary demographically, and vary graphically (cartoon, photo, logo). Facebook's Ads Manager was used over 7 weeks (6/10/13 - 7/29/13), targeted by age (18-25), location (U.S.), and language (English), and employed multiple ad types (newsfeed, standard, promoted posts, sponsored stories) and keywords. Ads linked to the online screening survey or study Facebook page. The 36 different ads generated 3,198,373 impressions, 5,895 unique clicks, at an overall cost of $2,024 ($0.34/click). Images of smoking and newsfeed ads had the greatest reach and clicks at the lowest cost. Of 5,895 unique clicks, 586 (10%) were study eligible and 230 (39%) consented. Advertising costs averaged $8.80 per eligible, consented participant. The final study sample (n=79) was largely Caucasian (77%) and male (69%), averaging 11 cigarettes/day (SD=8.3) and 2.7 years smoking (SD=0.7). Facebook is a useful, cost-effective recruitment source for young adult smokers. Ads posted via newsfeed posts were particularly successful, likely because they were viewable via mobile phone. Efforts to engage more ethnic minorities, young women, and smokers motivated to quit are needed. PMID:25045624

    Objective To determine whether smokers smoking from packs required under Australia's plain packaging law had different smoking beliefs and quitting thoughts, compared with those still smoking from branded packs. Design Cross-sectional survey during the roll-out phase of the law, analysed by timing of survey. Setting Australian state of Victoria, November 2012. Participants 536 cigarette smokers with a usual brand, of whom 72.3% were smoking from a plain pack and 27.7% were smoking from a branded pack. Primary outcome measures Perceived quality and satisfaction of cigarettes compared with 1 year ago, frequency of thoughts of smoking harm, perceived exaggeration of harms, frequency of thoughts of quitting, quitting priority in life, intention to quit, approval of large graphic health warnings and plain packaging. Results Compared with branded pack smokers, those smoking from plain packs perceived their cigarettes to be lower in quality (adjusted OR (AdjOR)=1.66, p=0.045), tended to perceive their cigarettes as less satisfying than a year ago (AdjOR=1.70, p=0.052), were more likely to have thought about quitting at least once a day in the past week (AdjOR=1.81, p=0.013) and to rate quitting as a higher priority in their lives (F=13.11, df=1, p<0.001). Plain pack smokers were more likely to support the policy than branded pack smokers (AdjOR=1.51, p=0.049). Branded and plain pack smokers did not differ on measures of less immediate smoking intentions, frequency of thoughts about harms or perceived exaggeration of harms. Appeal outcomes, but not other outcomes, were sensitive to the extent of roll-out, with responses from branded pack smokers approaching those of plain pack smokers, once 80% of survey respondents were smoking from plain packs 1–2 weeks before the December implementation date. Conclusions The early indication is that plain packaging is associated with lower smoking appeal, more support for the policy and more urgency to quit among adult smokers

    Objective: To examine the prevalence and correlates of internet cigarette purchasing among adult smokers. Design: Analysis of internet purchasing in data from a population based telephone survey of New Jersey households. Logistic regression was used to determine factors associated with internet cigarette purchasing, adjusting for year, demographic, and smoking behaviour variables. Participants: 3447 current cigarette smokers pooled from three cross sectional surveys conducted in 2000, 2001, and 2002. Main outcome measures: Ever purchasing tobacco and usually buying cigarettes via the internet. Results: Among all current cigarette smokers, ever having purchased tobacco via the internet increased from 1.1% in 2000 to 6.7% in 2002 and usually buying cigarettes via the internet increased from 0.8% in 2000 to 3.1% in 2002. Among current cigarette smokers with internet access, ever having purchased tobacco via the internet was higher among those who reported smoking 31 or more cigarettes per day (adjusted odds ratio (OR) 3.9, 95% confidence interval (CI) 1.5 to 10.2) and those without a past year quit attempt (adjusted OR 1.8, 95% CI 1.1 to 3.0). Usually purchasing cigarettes via the internet was higher among those aged 45–64 years (adjusted OR 4.4, 95% CI 1.1 to 17.1) and who reported having their first cigarette ⩽ 30 minutes after waking (adjusted OR 3.3, 95% CI 1.2 to 9.2). Conclusions: Although higher prices are known to reduce the demand for cigarettes, internet cigarette purchasing is likely to weaken this effect, particularly among heavy, more dependent smokers who are less interested in quitting.

    Objectives Hookah tobacco smoking has grown steadily in popularity among young adults in the United States. Little attention has been given to the relationship between hookah smoking and another behavior that is common among young adults – alcohol use. The purpose of this study was to examine hookah and alcohol use among young adults. Methods Forty young adult hookah smokers (55% female) participated in focus group sessions on hookah use beliefs and a brief survey examining hookah and alcohol use including drinking alcohol before, during, or after smoking hookah. Results Quotes from the focus groups indicated that alcohol use may promote hookah use among individuals who have little or no hookah smoking experience. Alcohol use, binge drinking, and alcohol use before, during, and after hookah use were common among the participants regardless of legal drinking age status. Nearly half of the participants preferred to drink alcohol while smoking hookah due to the improved physical and social effects they associated with combining the 2 behaviors. Conclusions For some young adult hookah smokers, alcohol appears to enhance the hookah smoking experience and may play a role in hookah smoking initiation. Future research and interventions should address the association between hookah and alcohol use. PMID:26248176

    Background Little is known about the demand for smoking cessation services in settings with high smoking prevalence rates. Furthermore, acceptability of text messaging and Internet as delivery mechanisms for smoking cessation programs in non-developed countries is under-reported. Given the cost effectiveness of technology-based programs, these may be more feasible to roll out in settings with limited public health resources relative to in-person programs. Findings 148 adult smokers took part in a community-based survey in Ankara, Turkey. Two in five (43%) respondents reported typically smoking their first cigarette within 30 minutes of waking. Many participants expressed a desire to quit smoking: 27% reported seriously thinking about quitting in the next 30 days; 53% reported at least one quit attempt in the past year. Two in five smokers wanting to quit reported they were somewhat or extremely like to try a smoking cessation program if it were accessible via text messaging (45%) or online (43%). Conclusions Opportunities for low-cost, high-reach, technology-based smoking cessation programs are under-utilized. Findings support the development and testing of these types of interventions for adult smokers in Turkey. PMID:21806793

    What is already known on this topic? Quitting smoking is beneficial to health at any age, and cigarette smokers who quit before age 35 years have mortality rates similar to those of persons who never smoked. What is added by this report?During 2001–2010, the proportion of adult cigarette smokers who had made a quit attempt in the past year increased significantly in 29 states and the U.S. Virgin Islands. During 2011–2013, the proportion who had made a quit attempt increased in Hawaii and Puerto Rico and decreased in New Mexico. In 2013, the proportion who had made a quit attempt ranged from 56.2% (Kentucky) to 76.4% (Puerto Rico and Guam) with a median of 65.9%, and was generally lower in older age groups. What are the implications for public health practice? Continued implementation of effective evidence-based public health interventions can reduce the health and costs impacts of smoking-related disease and death and accelerate progress toward meeting the Healthy People 2020 target to increase to ≥80% the proportion of U.S. adult cigarette smokers who made a quit attempt in the past year. These interventions include increasing the price of tobacco products, implementing comprehensive smoke-free laws, conducting educational mass media campaigns, and providing insurance coverage for all effective cessation treatments as well as access to quitlines.

    Cigarette smoking is a world-wide habit and an important risk factor for cancer. It was known that cigarette smoking can change the expression of circulating microRNAs (miRNAs) in healthy middle-aged adults. However, it remains unclear whether cigarette smoking can change the levels of circulating miRNAs in young healthy smokers and whether there are differences in cancer susceptibility for the two cases. In this study, the miRNA expression profiles of 28 smokers and 12 non-smokers were determined by Agilent human MicroRNA array. We further performed bioinformatics analysis for the differentially expressed miRNAs. The result showed that 35 miRNAs were differentially expressed. Among them, 24 miRNAs were up-regulated and 11 miRNAs were down-regulated in smokers. Functional enrichment analysis showed that the deregulated miRNAs are related to immune system and hormones regulation. Strikingly, the up-regulated miRNAs are mostly associated with hematologic cancers, such as lymphoma, leukemia. As a comparison, the up-regulated plasma miRNAs in middle-aged smokers are mostly associated with solid cancers, such as hepatocellular carcinoma and lung cancer, suggesting that smoking could have different influences on young adults and middle-aged adults. In a conclusion, we identified the circulating miRNAs deregulated by cigarette smoking and revealed that the age-dependent deregulated miRNAs tend to be mainly involved in different types of human cancers.

    Daily activity levels were investigated as related to sleep quality in young adult college students aged 18 to 30 years. 85 participants (20 men, 65 women) completed the Young Adult Daily Activity Scale (YADAS). This 37-item checklist has 34 items based on focus group discussion points of college students' typical daily activities and three blank items for students to include their daily activities if not in the listing. The tabulation of type and amount of waking daily activities represents a unique measurement of factors that may affect sleep quality. The participants also rated their typical sleep quality using a standard 5-point scale (low indicating poor sleep). Correlations of sleep ratings and activities were not significant. PMID:21667753

    Background: Smoking cigarettes is a risk factor for many physical and mental diseases. About five million people die of smoking every year. Understanding the concept of cigarette smoking can help people develop their knowledge with regard to smoking. A qualitative research seems essential to detect these concepts. Therefore, the present study aims to take into account the experience of adult smokers with regard to the concept of smoking. Materials and Methods: This is a qualitative content analysis study conducted on 12 smokers in four selected cities in Iran. Data were collected by in-depth, semi-structured interviews, transcribed verbatim, and simultaneously coded. Subsequently, they were analyzed using the content analysis method. Results: In the present study, eight concepts (themes), 22 subcategories, and 81 codes have emerged. The obtained concepts are physics of a cigarette, addiction and dependency, habit, feel the need, pleasure, seeking peace, mental involvement, and self-induction. Conclusions: The participants’ experiences with regard to cigarette smoking can affect their understanding of the concepts of smoking. The understanding of these concepts by nurses and smokers can enhance their knowledge about the existing facts of smoking, which can act as a foundation for designing preventive methods and smoking cessation programs.

    Oral cannabinoids are taken for medicinal or recreational purposes, yet little is known about tolerance to their effects after high-dose extended exposure. The development of tolerance to effects of around-the-clock oral synthetic Δ9-tetrahydrocannabinol (THC) (20 mg every 3.5-6 h) was evaluated in 13 healthy male daily cannabis smokers residing on a secure research unit: 40 mg on Day 1; 100 mg on Days 2-4; 120 mg on Days 5-6. Systolic and diastolic blood pressure (BP), heart rate, and symptoms of subjective intoxication (100 mm visual-analogue scales, VAS) were assessed the morning of Day 1 (before any oral THC), and on Days 2, 4 and 6, every 30 min for 3 h after the first morning THC dose. Morning subjective intoxication ratings increased from Days 1 to 2, and then declined on Days 4 and 6. The morning THC dose increased intoxication ratings on Day 2, but had less effect on Days 4 and 6, a pattern consistent with tolerance. THC lowered BP and increased heart rate over the six days. Plasma THC and 11-OH-THC concentrations increased significantly over the first five days of dosing. Six days of around-the-clock, oral THC produced tolerance to subjective intoxication, but not to cardiovascular effects. PMID:23074216

    Background Passive exposure to combustible cigarette use has been shown to act as a cue to increase smoking urge. Given the resemblance of e-cigarettes and other electronic nicotine delivery systems (ENDS) to combustible cigarettes, we examined whether these devices could also act as a cue to increase smoking desire and urges in those passively exposed. Methods Young adult daily smokers (age 18–35 years; N=60) completed subjective ratings before and after exposure to a study confederate drinking bottled water (control cue) and then smoking either a combustible or e-cigarette (active cue). Smoking desire and urge ratings were measured with visual analogue scale items for desire for a regular and an e-cigarette and the Brief Questionnaire of Smoking Urges. Results Passive exposure to both the e-cigarette and combustible cigarette cue significantly increased observers’ ratings of desire and urge to smoke a regular cigarette (all ps<0.05). Exposure to the e-cigarette cue but not the regular cigarette cue also increased desire to smoke an e-cigarette (p<0.01). Conclusions The results provide the first evidence in a controlled setting that electronic cigarette exposure may evoke smoking urges in young adult daily smokers. With replication, these findings may have relevance for ENDS regulation and policy. PMID:24848637

    Identifying relations of Attention-Deficit Hyperactivity Disorder (ADHD) symptom dimensions to individual facets of the tobacco withdrawal syndrome could elucidate the mechanisms linking ADHD and regular smoking. This study examined the unique relations of inattention (IN) and hyperactivity-impulsivity (HI) symptom dimensions of ADHD to a variety of tobacco withdrawal symptoms. 132 community-dwelling adult smokers recruited without regard to ADHD status completed a self-report measure of ADHD symptoms experienced over the past 6 months at a baseline visit. At two subsequent experimental sessions (one following overnight tobacco deprivation and one nondeprived; order counterbalanced), participants completed measures of tobacco withdrawal symptoms, mood, and desire to smoke. Preliminary analyses showed that higher levels of IN and HI symptoms were both associated with higher levels of negative affect and concentration difficulties during nondeprived (“baseline”) states (Ps < .01). Over and above nondeprived ratings, higher levels of HI symptoms were associated with larger deprivation-induced increases in negative affect, concentration problems, and desire to smoke, particularly for negative affect relief, during deprived states (Ps < .01). ADHD symptoms, particularly HI symptoms, are associated with more severe exacerbations in abstinence-induced withdrawal symptoms, which could be an important mechanism of ADHD-smoking comorbidity. These findings suggest the need for clinical studies examining the role of these unique and potentially more severe withdrawal profiles experienced by smokers with high-levels of ADHD symptoms in smoking reinstatement and cessation outcomes.

    This collaborative, community-engaged project developed and tested a Culturally-Tailored Treatment (CTT) for American Indian/Alaska Native (AI/AN) smokers in the Menominee tribal community. One hundred three adult AI/AN smokers were randomized to receive either Standard Treatment (n= 53) or CTT (n = 50) for smoking cessation. Both treatment conditions included 12 weeks of varenicline and four individual counseling sessions but differed in terms of cultural tailoring of the counseling. The primary outcome was 7-day biochemically-confirmed point-prevalence abstinence (PPA) at the 6-month end-of-study visit. Both intention-to-treat (ITT) and responder-only analyses were conducted. There were no statistically significant group differences in 7-day PPA. The overall ITT abstinence rate at 6 months was 20%; the responder-only rate was 42%. The current study represents the first randomized smoking cessation clinical trial testing a culturally-tailored smoking cessation intervention designed for a specific AI/AN tribal community that combined FDA-approved cessation medication (varenicline) and innovative cultural intervention components.

    Objective In contrast to proposals that physical activity (PA) can be a substitute for alcohol use, people who engage in greater overall PA generally consume more alcohol on average than less-active peers. Acknowledging that both PA and alcohol use vary considerably from day-to-day, this study evaluated whether established associations reflect daily behavioral coupling within-person, are an artifact of procedures that aggregate behavior over time, or both. Methods A lifespan sample of 150 adults (aged 19–89 years) completed three 21-day measurement bursts of a daily diary study. At the end of each day, they reported on their PA and alcohol consumption. Data were analyzed in a negative binomial multilevel regression. Results As expected, both behaviors exhibited limited between-person variation. After controlling for age, sex, and seasonal and social calendar influences, daily deviations in PA were significantly associated with daily total alcohol use. Once the within-person process linking PA and alcohol use was controlled, usual PA and total alcohol use were not associated. Conclusions The established between-person association linking PA and alcohol use reflects the aggregation of a daily process that unfolds within-people over time. Further work is needed to identify mediators of this daily association and to evaluate causality, as well as to investigate these relations in high-risk samples. PMID:25222084

    Small cigar smoking among young adult cigarette smokers may be attributed to their exposure to its advertisements and promotions. We examined the association between exposure to a celebrity music artist's endorsement of a specific brand of small cigars and young adult cigarette smokers' susceptibility to smoking that brand. Venue-based sampling procedures were used to select and survey a random sample of 121 young adult cigarette smokers, aged 18-35. Fourteen percent reported exposure to the artist's endorsement of the small cigar and 45.4% reported an intention to smoke the product in the future. The odds of small cigar smoking susceptibility increased threefold for those who reported exposure to the endorsement compared to those not exposed (OR = 3.64, 95% CI 1.06 to 12.54). Past 30-day small cigar use (OR = 3.30, 95% CI 1.24 to 8.74) and past 30-day cigar use (OR = 5.08, 95% CI 1.23, 21.08) were also associated with susceptibility to smoke a small cigar. An association between young adult cigarette smokers' exposure to the music artist's small cigar endorsement and their susceptibility to smoke small cigars was found. This association underscores the importance of monitoring small cigar promotions geared toward young people and their impact on small cigar product smoking.

    The authors studied predictors of methylphenidate-induced increases in blood pressure (BP). In this secondary analysis of a randomized, double-blind, placebo-controlled smoking cessation trial, nonhypertensive adult smokers with attention deficit hyperactivity disorder randomized to osmotic-release oral system methylphenidate (OROS-MPH; n=115) were one-to-one matched on baseline systolic blood pressure (SBP; ±5 mm Hg) with participants randomized to placebo (n=115) and followed for 10 weeks. In adjusted mixed linear models of SBP and diastolic blood pressure (DBP), baseline normal SBP (p<.0001) and DBP (p<.0001) were associated with significant OROS-MPH-induced increases compared to placebo, whereas significant increases were not observed in participants with baseline prehypertensive SBP (p=.27) and DBP (p=.79). Participants randomized to OROS-MPH with baseline normal BP had increased odds of developing either systolic (odds ratio 3.32, 95% confidence interval, 1.41–8.37, p=.006) or diastolic prehypertension (OR 4.32, 95% CI, 1.56–14.0, p=.004) compared to placebo, using simple logistic regression. The authors demonstrated an augmented OROS-MPH-induced BP elevation and risk of prehypertension in adults with baseline normal BP. Significantly increased BP was not observed in adults with baseline prehypertension. PMID:23339731

    Introduction: In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP) among young adult male smokers. Methods: A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18–45 years old. Results: The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811), and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364)  in the sample of higher education young adult males Conclusions: Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers. PMID:25689992

    Objective This article describes the daily self-management practices of older adults with arthritis and examines the association of symptom experience with the use of self-management behaviors. Method 197 African American and White participants completed a baseline interview and six sets of three follow-up daily-diary interviews at monthly intervals. Results Arthritis was reported by 63.5%. Arthritis self-management reported included complementary therapies, over-the-counter (OTC) and prescription medications, foods or beverages, and home remedies. Odds of implementing these self-care practices were greater on days with joint pain, swelling, and stiffness. Although, 78.0% and 72.4% of all participants reported staying in bed or cutting back on activities in response to joint symptoms, these self-management activities were not associated with having arthritis. Conclusions Focusing on daily responses to symptoms demonstrates that older adults actively manage arthritis symptoms using a wide variety of measures, including complementary therapies.

    This study uses longitudinal data from the International Tobacco Control Southeast Asia (ITC-SEA Thailand) survey to explore patterns and predictors of successful quitting among Thai adult smokers as a function of time quit. A cohort of a representative sample of 2000 smokers was surveyed four times from 2005 to 2009. A sample of 1533 individuals provided data for at least one of the reported analyses. Over the four years of follow-up, 97% made attempts to quit. Outcomes were successful quitting/relapse: (a) quit attempts of at least one month (short-term relapse, 43%) (57% remaining quit); (b) surviving at least six months (medium-term) (31%); (c) relapse between one and six months (45%); (d) having continuously quit between Waves 3 and 4 (sustained abstinence) (14%); and (e) relapse from six months on (44%) compared to those who continuously quit between Waves 3 and 4 (56%). Predictors for early relapse (<1 month) differ from longer-term relapse. Age was associated with reduced relapse over all three periods, and was much stronger for longer periods of abstinence. Cigarette consumption predicted relapse for short and medium terms. Self-assessed addiction was predictive of early relapse, but reversed to predict abstinence beyond six months. Previous quit history of more than one week was predictive of early abstinence, but became unrelated subsequently. Self-efficacy was strongly predictive of abstinence in the first month but was associated with relapse thereafter. Some determinants of relapse change with time quit, but this may be in somewhat different to patterns found in the West. PMID:26404335

    The novelty of e-cigarettes and ambiguity about their effects may foster informal sharing of information, such as through social interactions. We aimed to describe smokers' social interactions about e-cigarettes and their recommendations that others use e-cigarettes. Data were collected from 2149 adult smokers in North Carolina and California who participated in a study of the impact of pictorial cigarette pack warnings. In the previous month, almost half of participants (45%) reported talking to at least one person about e-cigarettes and nearly a third of participants (27%) recommended e-cigarettes to someone else. Smokers recommended e-cigarettes to cut back on smoking (57%), to quit smoking (48%), for health reasons (36%), and for fun (27%). In adjusted analyses, more frequent e-cigarette use, positive views about typical e-cigarette users, and attempting to quit smoking in the past month were associated with recommending e-cigarettes for health reasons (all p < 0.05). Social interactions appear to be a popular method of information-sharing about e-cigarettes among smokers. Health communication campaigns may help to fill in the gaps of smokers' understanding of e-cigarettes and their long-term effects.

    This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed.

    The role of The Transtheoretical Model (TTM) in predicting relapse is limited. We aimed to assess whether this model can be utilised to predict relapse during the action stage. The participants included 120 smokers who had abstained from smoking for at least 24 hours following two Malaysian universities' smoking cessation programme. The smokers who relapsed perceived significantly greater advantages related to smoking and increasing doubt in their ability to quit. In contrast, former smokers with greater self-liberation and determination to abstain were less likely to relapse. The findings suggest that TTM can be used to predict relapse among quitting smokers.

    Despite increases in nondaily smoking among young adults, no prior research has aimed to develop and test an intervention targeting this group. Thus, we aimed to develop and test the feasibility, acceptability, and potential effectiveness of an online intervention targeting college student nondaily smokers. We conducted a one-arm feasibility and acceptability trial of a four-week online intervention with weekly contacts among 31 college student nondaily smokers. We conducted assessments at baseline (B), end of treatment (EOT), and six-week followup (FU). We maintained a 100% retention rate over the 10-week period. Google Analytics data indicated positive utilization results, and 71.0% were satisfied with the program. There were increases (P < .001) in the number of people refraining from smoking for the past 30 days and reducing their smoking from B to EOT and to FU, with additional individuals reporting being quit despite recent smoking. Participants also increased in their perceptions of how bothersome secondhand smoke is to others (P < .05); however, no other attitudinal variables were altered. Thus, this intervention demonstrated feasibility, acceptability, and potential effectiveness among college-aged nondaily smokers. Additional research is needed to understand how nondaily smokers define cessation, improve measures for cessation, and examine theoretical constructs related to smoking among this population.

    2012-04-01

    Plain (unbranded) packaging for cigarettes is at the top of the tobacco control agenda in both Australia and Europe. The evidence suggests that it will benefit public health by decreasing the appeal of tobacco products and increasing the power of the health warning. The tobacco industry instead argues that plain packaging would make it easier to counterfeit cigarettes, which would both confuse consumers and reduce price; thereby increasing consumption. Using focus group research we examined young adult smokers (N = 54) perceptions of, and ability to recognize, illicit tobacco and the possible impact of plain packaging on illicit tobacco purchasing behaviour. We found that the pack has no impact on the decision to buy illicit tobacco. Smokers were easily able to identify counterfeit cigarettes, not least by the pack, and buy it knowingly and in the full expectation that it will be inferior in quality. Illicit tobacco purchase, including that for counterfeit tobacco, was instead driven by availability and price. Given the extremely low manufacturing cost, per pack, of certain types of illicit cigarettes, it is difficult to envisage how plain packaging would alter the price of illicit tobacco in any meaningful way. The findings therefore suggest that a move to plain packaging would have no impact on young adult smokers' purchase behaviour.

    Transdermal nicotine almost doubles tobacco cessation rates; however, little is known about what happens to smokers during the quit process when they are wearing the nicotine patch and are confronted with high-risk smoking triggers. This is particularly important for smokers with psychological disorders who disproportionately represent today's smokers and have more trouble quitting. Using a mixed between- and within-subjects design, smokers with anxiety disorders (n=61) and smokers without any current Axis I disorders (n=38) received transdermal nicotine (21 mg) or a placebo patch over two assessment days separated by 48 hr. Urge to smoke was evaluated during a 5-hr patch absorption period (reflecting general smoking deprivation) and during imaginal exposure to theoretically high-risk triggers containing smoking cues, anxiety cues, both, or neutral cues. No differences were observed between smokers with and without anxiety disorders. Significant Patch×Time and Patch×Cue Content interactions were found. Both patch conditions experienced an increase in urge during the deprivation period, but postabsorption urge was significantly higher in the placebo condition, suggesting that transdermal nicotine attenuated the degree to which urge to smoke increased over time. During the cue reactivity trials, when participants received the nicotine patch, they experienced significantly lower urge in response to both smoking-only and neutral cues, but not when anxiety cues were present (alone or in combination with smoking cues). These data suggest that transdermal nicotine alleviates urge only under certain circumstances and that adjunctive interventions are likely necessary to address smoking urges in response to spikes in distress among smokers trying to quit.

    Marijuana withdrawal contributes to the high relapse rates in individuals seeking treatment for marijuana-use disorders. Quetiapine, an atypical antipsychotic, reduces characteristic symptoms of marijuana withdrawal in a variety of psychiatric conditions including mood lability, sleep disruption, and anorexia. This human laboratory study investigated the effectiveness of quetiapine to decrease marijuana withdrawal and relapse to marijuana use in nontreatment seeking marijuana smokers. Volunteers were maintained on placebo or quetiapine (200 mg/day) in this double-blind, counter-balanced, within-subject study consisting of two 15-day medication phases, the last 8 days of which were inpatient. On the first inpatient day, active marijuana (6.2% delta (9)-tetrahydrocannabinol [THC]) was repeatedly smoked under controlled conditions. For the next 3 days, inactive marijuana (0.0% THC) was available for self-administration (withdrawal). On the subsequent 4 days, active marijuana (6.2% THC) was available for self-administration (relapse). Volunteers (n = 14) who smoked an average of 10 marijuana cigarettes/day, 7 days/week completed the study. Under placebo, withdrawal was marked by increased subjective ratings of negative mood, decreased sleep quality, decreased caloric intake, and weight loss. Compared to placebo, quetiapine improved sleep quality, increased caloric intake, and decreased weight loss. However, quetiapine increased marijuana craving and marijuana self-administration during the relapse phase. These data do not suggest that quetiapine shows promise as a potential treatment for marijuana dependence. PMID:22741619

    The novelty of e-cigarettes and ambiguity about their effects may foster informal sharing of information, such as through social interactions. We aimed to describe smokers’ social interactions about e-cigarettes and their recommendations that others use e-cigarettes. Data were collected from 2149 adult smokers in North Carolina and California who participated in a study of the impact of pictorial cigarette pack warnings. In the previous month, almost half of participants (45%) reported talking to at least one person about e-cigarettes and nearly a third of participants (27%) recommended e-cigarettes to someone else. Smokers recommended e-cigarettes to cut back on smoking (57%), to quit smoking (48%), for health reasons (36%), and for fun (27%). In adjusted analyses, more frequent e-cigarette use, positive views about typical e-cigarette users, and attempting to quit smoking in the past month were associated with recommending e-cigarettes for health reasons (all p < 0.05). Social interactions appear to be a popular method of information-sharing about e-cigarettes among smokers. Health communication campaigns may help to fill in the gaps of smokers’ understanding of e-cigarettes and their long-term effects. PMID:27527199

    We analyzed data from the Global Adult Tobacco Survey (GATS) from 21 countries to categorize smokers by stages of cessation and highlight interventions that could be tailored to each stage. GATS is a nationally representative household survey that measures tobacco use and other key indicators by using a standardized protocol. The distribution of smokers into precontemplation, contemplation, and preparation stages varied by country. Using the stages of change model, each country can design and implement effective interventions suitable to its cultural, social, and economic situations to help smokers advance successfully through the stages of cessation.

    Objective Many studies have suggested exposure to secondhand smoke (SHS) is a risk factor for various somatic diseases, but only few studies based on small sample size or specific groups have explored the association between passive smoking and mental distress. We performed this study to examine the relationship between passive smoking and mental distress in adult never-smokers of north-east China. Methods Multistage, stratified random cluster sampling design was used in this cross-sectional study in 2012. A total of 12 978 never-smokers from Jilin, north-east China, were included. Data on passive smoking and baseline characteristics were collected by face-to-face interviews. The 12-item General Health Questionnaire (GHQ-12) was used to measure mental health status. Rao-Scott χ2 tests were used to compare the prevalence between different groups; multivariable logistic regression was used to assess the association between passive smoking and mental distress, and Spearman rank analysis was employed to assess the correlation between passive smoking and GHQ-12 scores. Results The estimated prevalence of mental distress among never-smokers in Jilin province is 24.5%, and the estimated prevalence of passive smoking among the mental distressing group is 65.0%. After adjusting for gender, age, region, body mass index (BMI), occupation, marriage, education, drinking status and family monthly income per capita, passive smoking conferred a risk for mental distress (adjusted OR=1.26, 95% CI 1.13 to 1.40). A high proportion of adults, especially women, were passive smokers at home, but for men, passive smoking was more common at workplace. The more frequently participants exposed to SHS, the higher GHQ-12 scores they got. Conclusions Passive smoking is an important risk factor for mental distress in never-smokers of Jilin province, which reminds Chinese government of increasing the awareness of public health and take measure to prevent SHS, especially with regard to SHS

    Introduction: Limited longitudinal studies on smoking cessation have been reported in Asia, and it remains unclear whether determinants of quitting are similar to those found in Western countries. This study examined prospective predictors of smoking cessation among adult smokers in Thailand and Malaysia. Methods: Four thousand and four smokers were surveyed in Malaysia and Thailand in 2005. Of these, 2,426 smokers were followed up in 2006 (61% retention). Baseline measures of sociodemographics, dependence, and interest in quitting were used to predict both making quit attempts and point prevalence maintenance of cessation. Results: More Thai than Malaysian smokers reported having made quit attempts between waves, but among those who tried, the rates of staying quit were not considerably different between Malaysians and Thais. Multivariate analyses showed that smoking fewer cigarettes per day, higher levels of self-efficacy, and more immediate quitting intentions were predictive of both making a quit attempt and staying quit in both countries. Previous shorter quit attempts and higher health concerns about smoking were only predictive of making an attempt, whereas prior abstinence for 6 months or more and older age were associated with maintenance. Discussion: In Malaysia and Thailand, predictors of quitting activity appear to be similar. However, as in the West, predictors of making quit attempts are not all the same as those who predict maintenance. The actual predictors differ in potentially important ways from those found in the West. We need to determine the relative contributions of cultural factors and the shorter history of efforts to encourage quitting in Asia. PMID:20889478

    Background Implementation of tobacco plain packaging (PP) with larger graphic health warnings (GHWs) in Australia had positive effects on responses reflecting the specific objectives of the PP policy and on follow-up quitting-related cognitions and behaviours. The aim of this study was to examine predictive relationships between these proximal and distal outcomes. Methods A nationally representative sample of Australian adult cigarette smokers completed a baseline survey and a 1-month follow-up survey within the first year of policy implementation (n(weighted)=3125). Logistic regression analyses tested whether baseline measures of cigarette appeal, GHW effectiveness, perceived harm and concern/enjoyment predicted each of seven follow-up measures of quitting-related cognitions and behaviours, adjusting for baseline levels of the outcome and covariates. Results In multivariable models, we found consistent evidence that several baseline measures of GHW effectiveness positively and significantly predicted the likelihood that smokers at follow-up reported thinking about quitting at least daily, intending to quit, having a firm date to quit, stubbing out cigarettes prematurely, stopping oneself from smoking and having attempted to quit. Two of the quitting-related outcomes were also predicted by feeling more smoking-related concern than enjoyment. A smaller number of the appeal variables were prospectively associated with quitting-related outcomes, while believing that brands do not differ in harmfulness did not positively predict any outcomes. Conclusions These findings provide an initial insight into the pathways through which PP with larger GHWs may lead to changes in smoking behaviour. Future research should examine whether the effects are conditional on individual demographic and smoking characteristics.

    Risk beliefs and self-efficacy play important roles in explaining smoking-related outcomes and are important to target in tobacco control interventions. However, information is lacking about the underlying beliefs that drive these constructs. The present study investigated the interrelationships among young adult smokers' beliefs about the nature of nicotine addiction and smoking-related affect and cognitions (i.e., feelings of risk, worry about experiencing the harms of smoking, self-efficacy of quitting, and intentions to quit). Smokers (N=333) were recruited from two large universities. Results showed that quit intentions were associated with feelings of risk, but not with worry or self-efficacy. Furthermore, higher feelings of risk were associated with lower beliefs that addiction is an inevitable consequence of smoking and with lower beliefs that the harms of smoking are delayed. This suggests that it is important for health messages to counter the possible negative effects of messages that strongly emphasize the addictiveness of nicotine, possibly by emphasizing the importance of quitting earlier rather than later. The findings also add to the evidence base that feelings of risk are powerful predictors of behavioral intentions. Furthermore, our results suggest that in some circumstances, feelings of risk predict quit intentions beyond that predicted by worry and self-efficacy. Gaining additional understanding of the tobacco-related beliefs that can increase feelings of risk and incorporating those beliefs into educational campaigns may improve the quality of such campaigns and reduce tobacco use.

    Shisha (waterpipe) smoking is becoming a more prevalent form of tobacco consumption, and is growing worldwide, particularly among the young generation in the Middle East. This cross-sectional study aimed to determine the effects of shisha smoking on lung functions and Fractional Exhaled Nitric Oxide (FeNO) among Saudi young adults. We recruited 146 apparently healthy male subjects (73 control and 73 shisha smokers). The exposed group consisted of male shisha smokers, with mean age 21.54 ± 0.41 (mean ± SEM) range 17–33 years. The control group consisted of similar number (73) of non-smokers with mean age 21.36 ± 0.19 (mean ± SEM) range 18–28 years. Between the groups we considered the factors like age, height, weight, gender, ethnicity and socioeconomic status to estimate the impact of shisha smoking on lung function and fractional exhaled nitric oxide. Lung function test was performed by using an Spirovit-SP-1 Electronic Spirometer. Fractional Exhaled Nitric Oxide (FeNO) was measured by using Niox Mino. A significant decrease in lung function parameters FEV1, FEV1/FVC Ratio, FEF-25%, FEF-50%, FEF-75% and FEF-75-85% was found among shisha smokers relative to their control group. There was also a significant reduction in the Fractional Exhaled Nitric Oxide among Shisha smokers compared to control group. PMID:25233010

    Introduction Consumption of sugar-sweetened beverages (SSBs) is associated with cardiovascular disease risk factors. This study examined the relationships between SSB consumption and demographic, health behavior, health service, and health condition characteristics of adult patients of a network of federally qualified health centers (FQHCs) in a low-income, urban setting. Methods Validated, standardized self-reported health behavior questions were incorporated into the electronic health record (EHR) and asked of patients yearly, at 4 FQHCs. We conducted cross-sectional analysis of EHR data collected in 2013 from 12,214 adult patients by using logistic regression. Results Forty percent of adult patients consumed 1 or more SSBs daily. The adjusted odds ratios indicated that patients who consumed more than 1 SSB daily were more likely to be aged 18 to 29 years versus age 70 or older, current smokers versus never smoking, eating no servings of fruits and/or vegetables daily or 1 to 4 servings daily versus 5 or more servings daily, and not walking or biking more than 10 blocks in the past 30 days. Patients consuming 1 or more servings of SSBs daily were less likely to speak Spanish than English, be women than men, be diagnosed with type 2 diabetes versus no diabetes, and be diagnosed with hypertension versus no hypertension. Conclusion SSB consumption differed by certain demographic characteristics, health behaviors, and health conditions. Recording SSB intake and other health behaviors data in the EHR could help clinicians in identifying and counseling patients to promote health behavior changes. Future studies should investigate how EHR data on patient health behavior can be used to improve the health of patients and communities. PMID:25569695

    Introduction Pulmonary function is compromised in most smokers. Yet it is unknown whether exercise training improves pulmonary function and aerobic capacity in cigarette and hookah smokers and whether these smokers respond in a similar way as do non-smokers. Aim To evaluate the effects of an interval exercise training program on pulmonary function and aerobic capacity in cigarette and hookah smokers. Methods Twelve cigarette smokers, 10 hookah smokers, and 11 non-smokers participated in our exercise program. All subjects performed 30 min of interval exercise (2 min of work followed by 1 min of rest) three times a week for 12 weeks at an intensity estimated at 70% of the subject's maximum aerobic capacity (V.O2max). Pulmonary function was measured using spirometry, and maximum aerobic capacity was assessed by maximal exercise testing on a treadmill before the beginning and at the end of the exercise training program. Results As expected, prior to the exercise intervention, the cigarette and hookah smokers had significantly lower pulmonary function than the non-smokers. The 12-week exercise training program did not significantly affect lung function as assessed by spirometry in the non-smoker group. However, it significantly increased both forced expiratory volume in 1 second and peak expiratory flow (PEF) in the cigarette smoker group, and PEF in the hookah smoker group. Our training program had its most notable impact on the cardiopulmonary system of smokers. In the non-smoker and cigarette smoker groups, the training program significantly improved V.O2max (4.4 and 4.7%, respectively), v V.O2max (6.7 and 5.6%, respectively), and the recovery index (7.9 and 10.5%, respectively). Conclusions After 12 weeks of interval training program, the increase of V.O2max and the decrease of recovery index and resting heart rate in the smoking subjects indicated better exercise tolerance. Although the intermittent training program altered pulmonary function only partially, both

    Tobacco use is inextricably linked to a number of health risks both in the general and HIV-infected populations. There is, however, a dearth of research on effective tobacco control programs among people living with HIV, and especially among adolescents, young adults and pregnant women, groups with heightened or increased vulnerability secondary to tobacco use. Adolescents and young adults constitute a growing population of persons living with HIV infection. Early and continued tobacco use in this population living with a disease characterized by premature onset multimorbidity and chronic inflammation is of concern. Additionally, there is an increased acuity for tobacco control among HIV-infected pregnant women to reduce pregnancy morbidity and improve fetal outcome. This review will provide an important summary of current knowledge of tobacco use among HIV-infected adolescents, young adults and pregnant women. The effects of tobacco use in these specific populations will be presented and the current state of tobacco control within these populations, assessed. PMID:23778059

    Background: Single cigarette use and its implications have rarely been studied among adults. Objective: To assess perceptions, prevalence and correlates of single cigarette purchase behaviour and its relation to harm reduction. Design: Focus group transcripts and cross-sectional data were analysed. Setting and participants: Focus groups among convenience samples of adult smokers in two Mexican cities and a population-based sample of 1079 adult smokers from the International Tobacco Control Policy Evaluation Project in four Mexican cities. Main outcome measures: Purchase of single cigarettes last time cigarettes were bought, frequency of purchasing single cigarettes in the previous month and intention to quit in the next 6 months. Results: Focus group data indicated that smokers bought single cigarettes as a harm reduction strategy. Survey data indicated that 38% of participants purchased single cigarettes in the last month and 10% purchased them the last time they bought cigarettes, with more frequent consumption among young adults and those with lower income. Purchasing single cigarettes was independently associated with the frequency of using single cigarettes to reduce consumption and, less consistently, with the frequency of being cued to smoke after seeing single cigarettes for sale. Using single cigarettes to reduce consumption was positively associated with quit intention, whereas being cued to smoke by single cigarettes was negatively associated with quit intention. Conclusions: Study results suggest that some adult Mexican smokers purchase single cigarettes as a method to limit, cut down on and even quit smoking. Nevertheless, promotion of the availability of single cigarettes as a harm reduction strategy could provide additional smoking cues that undermine quit attempts and promote youth smoking.

    Introduction Health warning labels (HWLs) on tobacco packaging can be used to provide smoking cessation information, but the impact of this information is not well understood. Methods Online consumer panels of adult smokers from Canada, Australia and Mexico were surveyed in September 2012, January 2013 and May 2013; replenishment was used to maintain sample sizes of 1000 participants in each country at each wave. Country-stratified logistic Generalised Estimating Equation (GEE) models were estimated to assess correlates of citing HWLs as a source of information on quitlines and cessation websites. GEE models also regressed having called the quitline, and having visited a cessation website, on awareness of these resources because of HWLs. Results At baseline, citing HWLs as a source of information about quitlines was highest in Canada, followed by Australia and Mexico (33%, 19% and 16%, respectively). Significant increases over time were only evident in Australia and Mexico. In all countries, citing HWLs as a source of quitline information was significantly associated with self-report of having called a quitline. At baseline, citing HWLs as a source of information about cessation websites was higher in Canada than in Australia (14% and 6%, respectively; Mexico was excluded because HWLs do not include website information), but no significant changes over time were found for either country. Citing HWLs as a source of information about cessation websites was significantly associated with having visited a website in both Canada and Australia. Conclusions HWLs are an important source of cessation information. PMID:25052860

    Objective To assess the impact of Mexico City and federal smoke-free legislation on secondhand tobacco smoke (SHS) exposure and support for smoke-free laws. Material and Methods Pre- and post-law data were analyzed from a cohort of adult smokers who participated in the International Tobacco Control (ITC) Policy Evaluation Survey in four Mexican cities. For each indicator, we estimated prevalence, changes in prevalence, and between-city differences in rates of change. Results Self-reported exposure to smoke-free media campaigns generally increased more dramatically in Mexico City. Support for prohibiting smoking in regulated venues increased overall, but at a greater rate in Mexico City than in other cities. In bars and restaurants/cafés, self-reported SHS exposure had significantly greater decreases in Mexico City than in other cities; however, workplace exposure decreased in Tijuana and Guadalajara, but not in Mexico City or Ciudad Juárez. Conclusions Although federal smoke-free legislation was associated with important changes smoke-free policy impact, the comprehensive smoke-free law in Mexico City was generally accompanied by a greater rate of change.

    Introduction: The perception of negative health consequences is a common motive for quitting smoking, but specific information on the immediate health effects of occasional smoking among young adults is limited. Method: To examine the relationship between cigarette use and symptoms of (a) cough or sore throat and (b) shortness of breath or fatigue after regular activities among young adults, we performed online health screening of a random sample of 25,000 college undergraduates. The screening survey assessed demographic characteristics, smoking and related health behaviors, and respiratory symptoms in the previous 30 days. Results: The response rate was 26% (6,492/25,000). Among individuals reporting no smoking in the prior 30 days and smoking on 1–4, 5–10, 11–20, or 21–30 days, the prevalence of one or more days of cough/sore throat increased from 62.5% to 68.3%, 72.0%, 71.4%, and 73.7%, respectively (p < .001). Similarly, the prevalence of shortness of breath/fatigue increased from 42.7% to 47.1%, 56.2%, 59.5%, and 64.6%, respectively (p < .001). After controlling for demographics, other important health behaviors (e.g., days consuming alcohol and getting adequate sleep), and environmental tobacco smoke (ETS) exposure, reporting symptoms of cough/sore throat was associated with smoking on at least 21 days, whereas shortness of breath/fatigue was associated with smoking on 5 or more days. Among those reporting symptoms, increased number of days with respiratory symptoms was associated with smoking on most days as well as ETS exposure. Discussion: In conclusion, this cross-sectional study found that occasional smoking and ETS exposure were associated with an increase in the rate of respiratory symptoms (cough/sore throat and shortness of breath/fatigue) among young adults.

    Introduction Cigarette smoking has a negative effect on body reserve of antioxidants and cholesterol metabolism. Coenzyme Q10 (CoQ10), a potent antioxidant synthesized as part of the cholesterol pathway, is a potential biomarker for systemic oxidative stress. We aimed to investigate gender variation in plasma lipid profile and CoQ10 concentrations in healthy non-smokers and in smokers. Material and methods The study included 55 cigarette smokers (25 females and 30 males) and 51 non-smokers (25 females and 26 males) with the age range from 21 to 45 years, and who had no history of alcohol abuse or chronic diseases such as diabetes mellitus or obesity. Coenzyme Q10 plasma concentrations were measured by reverse-phase high performance liquid chromatography (HPLC) with ultraviolet detection. Fasting plasma glucose and lipid levels were determined by standard colorimetric methods. Results Our results showed that CoQ10 concentrations were significantly decreased in smokers, especially in females, than their non-smoker counterparts. Female smokers also exhibited a significant decrease in plasma concentrations of total cholesterol (TC), HDL-C, LDL-C, and atherogenic ratios HDL-C/TC and CoQ10/LDL-C than male counterparts. Plasma triglyceride concentrations were increased in smokers irrespective of gender. Plasma CoQ10 was relatively more associated with TC and LDL-C in female smokers than male smokers. Conclusions The adverse effects of smoking on body reserve of antioxidants and cholesterol metabolism are greater in females than in males, partially as a result of decreased CoQ10 plasma concentrations, HDL-C and total-cholesterol and abnormal atherogenicity indices.

    Langerhans cell histiocytosis (LCH) is a rare myeloid neoplasm characterized by the proliferation and dissemination of histiocytes. These in turn may cause symptoms ranging from isolated, infiltrative lesions to severe multisystem disease. Pulmonary Langerhans cell histiocytosis (PLCH) presents as a localized polyclonal proliferation of Langerhans cells in the lungs causing bilateral cysts and fibrosis. In adults, this rare condition is considered a reactive process associated with cigarette smoking. Recently, clonal proliferation has been reported with the presence of BRAF V600E oncogenic mutation in a subset of PLCH patients. Spontaneous resolution was described; however, based on case series, smoking cessation remains the most effective way to achieve complete remission and prevent long term complications related to tobacco. Herein, we report the case of an adult woman with biopsy-proven PLCH presenting with thoracic (T8) vertebral bone destruction. Both the lung and the bone diseases regressed following smoking cessation, representing a rare case of synchronous disseminated PCLH with bone localization. This observation underscores the contribution of cigarette smoking as a systemic trigger of both pulmonary and extrapulmonary bone lesions. A review of similar cases in the literature is also presented. PMID:25789184

    2014-01-01

    Objectives The raising unit price of cigarette has been shown to be one of the most effective ways of reducing cigarette consumption and increasing rates of successful quitting. However, researchers have shown that price-sensitive smokers have used a variety of strategies to mitigate the effect of the rising price of cigarettes on their smoking habits. In particular, 23–34% of adult smokers in the US use cheaper brands, and 18–55% use coupons or promotions. Little is known about the discount use by type of brands. As such, the main purpose of this analysis is to evaluate the uses and price discount effects of these price-related discounts by manufacturers and major brands. Setting An analysis based on the cross-sectional 2009–2010 National Adult Tobacco Survey (NATS). Participants 11 766 current smokers aged 18 or above in the USA. Primary outcome measures Price-related discount was defined as smokers who used coupons, rebates, buy-one-get-one-free, two-for-one or any other special promotions for their last cigarettes purchase. Results The use of price-related discounts and associated price impact vary widely by cigarette manufacturer and brand. Approximately one of three Camel, one of four Marlboro and one of eight Newport smokers used price-related discounts on their latest cigarette purchases. The average price reductions of discounts offered by Philip Morris (PM) or R.J. Reynolds (RJR) were around 29 cents per pack while that of Lorillard (Newport only) was 24 cents per pack. Cigarette brands that provided significant per pack price reductions include: PM Marlboro (28 cents), RJR brand Camel (41 cents), Doral (50 cents), Kool (73 cents) and Salem (80 cents), and Lorillard Newport (24 cents). Conclusions Policies that decrease price-minimisation strategies will benefit public health. PMID:24898086

The objective of this study was to determine the relative capabilities of self-selected walking speed (SSWS), maximal walking speed (MWS), and walking speed reserve (WSR) to provide insight into daily ambulatory activity (steps per day) in community-dwelling older adults. Sixty-seven older adults completed testing and activity monitoring (age 80.39 [6.73] years). SSWS (R2 = .51), MWS (R2 = .35), and WSR calculated as a ratio (R2 = .06) were significant predictors of daily ambulatory activity in unadjusted linear regression. Cutpoints for participants achieving < 8,000 steps/day were identified for SSWS (≤ 0.97 m/s, 44.2% sensitivity, 95.7% specificity, 10.28 +LR, 0.58 -LR) and MWS (≤ 1.39 m/s, 60.5% sensitivity, 78.3% specificity, 2.79 +LR, 0.50 -LR). SSWS may be a feasible proxy for assessing and monitoring daily ambulatory activity in older adults. PMID:26371593

    Self-conscious emotions play a role in regulating daily achievement strivings, social behavior, and health, but little is known about the processes underlying their daily manifestation. Emerging adults (n = 182) completed daily diaries for eight days and multilevel models were estimated to evaluate whether, how much, and why their emotions varied from day-to-day. Within-person variation in authentic pride was normally-distributed across people and days whereas the other emotions were burst-like and characterized by zero-inflated, negative binomial distributions. Perceiving social interactions as generally communal increased the odds of hubristic pride activation and reduced the odds of guilt activation; daily communal behavior reduced guilt intensity. Results illuminated processes through which meaning about the self-in-relation-to-others is constructed during a critical period of development. PMID:25859164

    Introduction Given increases in nondaily smoking and alternative tobacco use among young adults, we examined the nature of change of various tobacco product use among college students over a year and predictors of use at one-year follow-up. Methods An online survey was administered to students at six Southeast colleges and universities (N = 4,840; response rate = 20.1%) in Fall 2010, with attempts to follow up in Fall 2011 with a random subsample of 2,000 participants (N = 718; response rate = 35.9%). Data were analyzed from 698 participants with complete data regarding tobacco, marijuana, and alcohol use over a one-year period, perceived harm of tobacco use, and schemas of a “smoker” (as per the Classifying a Smoker Scale). Results Baseline predictors of current smoking at follow-up included being White (p = .001), frequency of smoking (p < .001), alternative tobacco use (p < .001), and perceived harm of smoking (p = .02); marginally significant predictors included marijuana use (p = .06) and lower scores on the Classifying a Smoker Scale (p = .07). Baseline predictors of current smoking at follow-up among baseline nondaily smokers included more frequent smoking (p = .008); lower Classifying a Smoker Scale score was a marginally significant predictor (p = .06). Baseline predictors of alternative tobacco use at follow-up included being male (p = .007), frequency of smoking (p = .04), alternative tobacco use (p < .001), and frequency of alcohol use (p = .003); marginally significant predictors included marijuana use (p = .07) and lower perceived harm of smokeless tobacco (p = .06) and cigar products (p = .08). Conclusions Tobacco control campaigns and interventions might target schemas of a smoker and perceived risks of using various tobacco products, even at low levels. PMID:25338288

    OBJECTIVES There is a shortage of information on metabolic costs of daily physical activities in older adults and the effect of having mobility impairments. The primary purpose of this study was to evaluate metabolic equivalent (MET) values on common daily tasks in men and women aged > 70 years compared to normative criteria. A secondary purpose was to determine the effect of having mobility impairments. DESIGN Cross-sectional observational study. SETTING University based research clinic PARTICIPANTS Forty-five participants aged 70 to 90 years of age (mean: 76.3 ± 5.1) volunteered to complete 17 daily activities, each lasting 10 minutes. MEASUREMENTS Oxygen consumption (VO2 = ml•kg−1•min−1) was measured through a mask by a portable gas analyzer and MET values were calculated as measured VO2/3.5 ml•kg−1•min−1. Values were compared to both normative values and between participants with and without mobility impairments. RESULTS Compared to the established normative criteria, measured METs were different in 14 of 17 tasks performed. Compared to measured METs, normative values underestimated walking leisurely (0.87 ± 0.12 METs) walking briskly (0.87 ± 0.12 METs ), and bed making (1.07 ± 0.10 METs ), but overestimated gardening (1.46 ± 0.12 METs) and climbing stairs (0.73 ± 0.18). Participants with impairments had significantly lower METs while gardening, vacuuming/sweeping, stair climbing, and walking briskly. However, when METs were adjusted for performance speed the metabolic costs were 16–27% higher for those with mobility impairments. CONCLUSION Compared to normative values, metabolic costs of daily activities are substantially different in older adults and having mobility impairments increases this metabolic cost. These results may have implications for practitioners to appropriately prescribe daily physical activities for healthy and mobility impaired older adults. PMID:22091979

    Individuals with Attention Deficit Hyperactivity Disorder (ADHD) smoke cigarettes at rates higher than the general population and questions have been raised about how stimulant drugs-the frontline pharmacological treatment for ADHD-influence smoking risk and behavior in those with ADHD. In the present study adult regular smokers with (n = 16) and without (n = 17) ADHD participated in 3 experimental sessions in which they completed a Progressive Ratio (PR) task to measure the relative reinforcing effects of cigarette smoking and money after oral administration of placebo and 2 active doses of methylphenidate (10 mg and 40 mg). We also measured attention and inhibitory control via a Continuous Performance Test (CPT). Methylphenidate had no effect on smoking-reinforced responding, attention, or inhibitory control in either group. Attention and inhibitory control were associated with smoking-reinforced responding, but unsystematically and only in the non-ADHD group. Several design features, such as the value of the monetary response option, the PR schedule, and the potential effects of smoking on attention and inhibitory control, could have contributed to the negative findings and are discussed as such. Although inconsistent with some previous human laboratory studies of stimulant drugs and smoking, results are consistent with recent trials of stimulant drugs as adjuncts for smoking cessation in adult smokers with ADHD. In general, methylphenidate at mild and moderate doses did not influence the relative reinforcing effects of cigarette smoking in adults with and without ADHD.

    Background Tobacco use remains the number one cause of preventable chronic disease and death in developed countries worldwide. In North America, smoking rates are highest among young adults. Despite that the majority of young adult smokers indicate wanting to quit, smoking rates among this age demographic have yet to decline. Helping young adults quit smoking continues to be a public health priority. Digital mobile technology presents a promising medium for reaching this population with smoking cessation interventions, especially because young adults are the heaviest users of this technology. Objective The primary aim of this trial is to determine the effectiveness of an evidence-informed mobile phone app for smoking cessation, Crush the Crave, on reducing smoking prevalence among young adult smokers. Methods A parallel randomized controlled trial (RCT) with two arms will be conducted in Canada to evaluate Crush the Crave. In total, 1354 young adult smokers (19 to 29 years old) will be randomized to receive the evidence-informed mobile phone app, Crush the Crave, or an evidence-based self-help guide known as “On the Road to Quitting” (control) for a period of 6 months. The primary outcome measure is a 30-day point prevalence of abstinence at the 6-month follow-up. Secondary outcomes include a 7-day point prevalence of abstinence, number of quit attempts, reduction in consumption of cigarettes, self-efficacy, satisfaction, app utilization metrics, and use of smoking cessation services. A cost-effectiveness analysis is included. Results This trial is currently open for recruitment. The anticipated completion date for the study is April 2016. Conclusions This randomized controlled trial will provide the evidence to move forward on decision making regarding the inclusion of technology-based mobile phone interventions as part of existing smoking cessation efforts made by health care providers. Evidence from the trial will also inform the development of future apps

    The objective of this study is to review the history of daily self-weighing for weight control, discuss the possibility that self-weighing may cause adverse psychological symptoms, and propose mechanisms that explain how self-weighing facilitates weight control. A systematic forward (citation) tracking approach has been employed in this study. In the early literature, experimental tests did not demonstrate a benefit of adding daily self-weighing to traditional behavioral modification for weight loss. More recent studies have shown that daily self-weighing combined with personalized electronic feedback can produce and sustain weight loss with and without a traditional weight loss program. Daily self-weighing appears to be effective in preventing age-related weight gain. Apart from these experimental findings, there is considerable agreement that the frequency of self-weighing correlates with success in losing weight and sustaining the weight loss. The early literature suggested frequent self-weighing may be associated with negative psychological effects. However, more recent experimental trials do not substantiate such a causal relationship. In conclusion, daily self-weighing may be a useful strategy for certain adults to prevent weight gain, lose weight, or prevent weight regain after loss. More research is needed to better understand the role of different types of feedback, who benefits most from self-weighing, and at what frequency. PMID:27127719

    Hormone signalling during critical periods organises the adult circadian timekeeping system by altering adult hormone sensitivity and shaping fundamental properties of circadian rhythmicity. However, the timing of when developmental oestrogens modify the timekeeping system is poorly understood. To test the hypothesis that alterations in postnatal oestrogenic signalling organise adult daily activity rhythms, we utilised aromatase knockout mice (ArKO), which lack the enzyme required for oestradiol synthesis. ArKO and wild-type (WT) males and females were administered either oestradiol (E) or oil (OIL) daily for the first 5 postnatal days (p1-5E and p1-5OIL , respectively) because this time encompasses the emergence of clock gene rhythmicity and light responsiveness in the suprachiasmatic nucleus, a bilateral hypothalamic structure regarded as the 'master oscillator'. After sexual maturation, gonadectomy and exogenous oestradiol supplementation, locomotor parameters were assessed. We determined that altered oestrogenic signalling in early life exerts organisational control over the expression of daily and circadian activity rhythms in adult mice. Specifically, p1-5E reduced total wheel running activity in male and female ArKO and female WT mice but had no effect on WT male activity levels. In females, wheel running was consolidated by p1-5E to the early versus late evening, a phenomenon characteristic of male mice. The time of peak activity was advanced by p1-5E in WT and ArKO females but not males. P1-5E shortened the length of the active phase (alpha) in WT males but had no effect on ArKO males or females of either genotypes. Finally, p1-5E altered the magnitude of photic-induced shifts, suggesting that developmental oestrogenic signalling impacts adult circadian functions. In the present study, we further define both a critical period of development of the adult timekeeping system and the role that oestrogenic signalling plays in the expression of daily and

    Hippocampal atrophy is associated with memory impairment and dementia and serves as a key biomarker in the preclinical stages of Alzheimer's disease. Physical activity, one of the most promising behavioral interventions to prevent or delay cognitive decline, has been shown to be associated with hippocampal volume; specifically increased aerobic activity and fitness may have a positive effect on the size of the hippocampus. The majority of older adults, however, are sedentary and have difficulty initiating and maintaining exercise programs. A modestly more active lifestyle may nonetheless be beneficial. This study explored whether greater objectively measured daily walking activity was associated with larger hippocampal volume. We additionally explored whether greater low-intensity walking activity, which may be related to leisure-time physical, functional, and social activities, was associated with larger hippocampal volume independent of exercise and higher-intensity walking activity. Segmentation of hippocampal volumes was performed using Functional Magnetic Resonance Imaging of the Brain's Software Library (FSL), and daily walking activity was assessed using a step activity monitor on 92, nondemented, older adult participants. After controlling for age, education, body mass index, cardiovascular disease risk factors, and the Mini Mental State Exam, we found that a greater amount, duration, and frequency of total daily walking activity were each associated with larger hippocampal volume among older women, but not among men. These relationships were specific to hippocampal volume, compared with the thalamus, used as a control brain region, and remained significant for low-intensity walking activity, independent of moderate- to vigorous-intensity activity and self-reported exercise. This is the first study, to our knowledge, to explore the relationship between objectively measured daily walking activity and hippocampal volume in an older adult population. Findings

    OBJECTIVE To analyze gender differences in the incidence and determinants of disability regarding instrumental activities of daily living among older adults. METHODS The data were extracted from the Saúde, Bem-Estar e Envelhecimento (SABE – Health, Wellbeing and Ageing) study. In 2000, 1,034 older adults without difficulty in regarding instrumental activities of daily living were selected. The following characteristics were evaluated at the baseline: sociodemographic and behavioral variables, health status, falls, fractures, hospitalizations, depressive symptoms, cognition, strength, mobility, balance and perception of vision and hearing. Instrumental activities of daily living such as shopping and managing own money and medication, using transportation and using the telephone were reassessed in 2006, with incident cases of disability considered as the outcome. RESULTS The incidence density of disability in instrumental activities of daily living was 44.7/1,000 person/years for women and 25.2/1,000 person/years for men. The incidence rate ratio between women and men was 1.77 (95%CI 1.75;1.80). After controlling for socioeconomic status and clinical conditions, the incidence rate ratio was 1.81 (95%CI 1.77;1.84), demonstrating that women with chronic disease and greater social vulnerability have a greater incidence density of disability in instrumental activities of daily living. The following were determinants of the incidence of disability: age ≥ 80 and worse perception of hearing in both genders; stroke in men; and being aged 70 to 79 in women. Better cognitive performance was a protective factor in both genders and better balance was a protective factor in women. CONCLUSIONS The higher incidence density of disability in older women remained even after controlling for adverse social and clinical conditions. In addition to age, poorer cognitive performance and conditions that adversely affect communication disable both genders. Acute events, such as a stroke

    We recorded the daily presence of Double-crested Cormorants (Phalacrocorax auritus) at the nesting island on Oneida Lake, New York, by monitoring the activities of 15 radio-tagged adults from July through September, 2000, using an automated data-logging receiver. A total of 24,464 acceptable detections was obtained for adult cormorants actively attempting to nest on the lake. Tagged cormorants had a bimodal dally activity pattern during the first month, with the fewest birds detected on the island at 09.00 h and 15.00 h Eastern daylight time. The pattern of activity appeared to change slightly in the second month of the study, representative of a post-breeding period for the colony, with a shift from a less synchronous pattern of departures to a greater focus on morning activity also centered around 09.30 h. These results correspond with daily observations of Great Cormorant (P. carbo) foraging activities reported for colonies in Africa and Poland. The data also support the possibility of nocturnal foraging activity, not previously reported for this species on their summer breeding grounds. No correlation was found between total number of daily detections and climatalogical factors or events.

    A key component of the Prototype Willingness Model is willingness, which reflects an openness to opportunity to perform a behavior in situations that are conducive to that behavior. Willingness has traditionally been tested using global, hypothetical assessments, and has not been examined at the daily level. We expected to find within-person variability in willingness to drink, such that on days with greater willingness, individuals would report greater drinking. A national sample (N=288) of young adults aged 18 to 20 (31.60% female) completed a Web-based survey that was comprised of measures of drinking and sexual behavior, including the Timeline Follow-Back (Sobell & Sobell, 1992). Findings show daily variability in willingness to drink (ICC=0.54), which suggests that there are substantial differences from day-to-day in this drinking-related cognition. Participants drank more on days when individuals also reported feeling more willing to drink than their own average level across the two weeks. Daily process level mechanisms allow greater insight into factors contributing to increased risk in-the-moment, which may point to targets for interventions aimed at improving adolescents' and young adults' abilities to make healthier choices in moments when they may be at greater risk for engaging in risky behaviors.

    Objectives Smoking prevalence is slow to reduce among Indigenous Australians of reproductive age. We analysed the relationships between age of smoking initiation, recalled initiation influences and self-assessment of smoking risks in Aboriginal smokers. Design, setting and participants A community-based cross-sectional survey of Aboriginal smokers aged 18–45 years (N=121; 58 men) was undertaken, using single-item measures. The Smoking Risk Assessment Target (SRAT) as the primary outcome measure enabled self-assessment of smoking risks from 12 options, recategorised into 3 groups. Participants recalled influences on their smoking initiation. Multinomial logistic regression modelling included age, gender, strength of urges to smoke, age at initiation (regular uptake) and statistically significant initiation influences on χ2 tests (‘to be cool’, alcohol and cannabis). Results Frequent initiation influences included friends (74%; SD 0.44), family (57%; SD 0.5) and alcohol (40%; SD 0.49). 54% (n=65) of smokers had the highest risk perception on the SRAT, selected by those who cared about the smoking risks and intended to quit soon. On multivariate analyses, compared with the highest level of SRAT, male gender, lower age of uptake and strong urges to smoke were significantly associated with the lowest level of SRAT, selected by those who refuted risks or thought they could not quit. Lower age of uptake and alcohol were associated with mid-level of SRAT, selected by those who cared about smoking risks, but did not consider quitting as a priority. Conclusions Characteristics of smoking initiation in youth may have far-reaching associations with how smoking risks are assessed by adults of reproductive age, and their intentions to quit smoking. Becoming a regular smoker at under the age of 16 years, and influences of alcohol on smoking uptake, were inversely associated with high-level assessment of smoking risks and intention to quit in regional Aboriginal smokers

    A central goal of daily stress research is to identify resilience and vulnerability factors associated with exposure and reactivity to daily stressors. The present study examined how age differences and global perceptions of stress relate to exposure and emotional reactivity to daily stressors. Sixty-seven younger (M age = 20) and 116 older (M age = 80) adults completed a daily stress diary and measures of positive and negative affect on 6 days over a 14-day period. Participants also completed a measure of global perceived stress. Results revealed that reported exposure to daily stressors is reduced in old age but that emotional reactivity to daily stressors did not differ between younger and older adults. Global perceived stress was associated with greater reported exposure to daily stressors in older adults and greater stress-related increases in negative affect in younger adults. Furthermore, across days on which daily stressors were reported, intraindividual variability in the number and severity of stressors reported was associated with increased negative affect, but only among younger adults.

    Empirical evidence supporting the interplay between pain intensity and tobacco smoking has been growing. The current investigation advances this work in three important ways: (1) controlling for negative affectivity and gender; (2) examining pain intensity in smokers from a community sample, rather than specialized pain treatment centers; and, (3) studying smokers who are highly motivated to quit. Participants were adult smokers (N=112; 35% female; Mage=41.4, SD=13.1) participating in a larger study examining barriers to cessation during a self-guided quit attempt. At baseline, participants completed self-report measures on pain intensity and smoking severity outcomes. As hypothesized, more intense pain was significantly associated with all four smoking severity variables: years as a daily smoker, current cigarettes per day, cigarettes per day during the heaviest lifetime smoking period, and current level of nicotine dependence. These associations remained when taking into account the variance accounted for by gender and negative affectivity. These data provide evidence that more intense pain is related to more severe smoking behavior and nicotine dependence. Pain reduction could be an important target in regard to smokers with chronic pain.

    A decline of cognitive abilities is a part of normal human ageing. However, recent research has demonstrated that an enriched environment can have a beneficial impact on cognitive function in old age. Accordingly, mentally and socially active lifestyles are associated with less cognitive decline in old age. Specific interventions such as computerized cognitive training programs for older adults are also known to have a positive effect on the level of cognitive functioning. Therefore, online platforms combining cognitive training with web 2.0 features may yield multiple benefits for older users. However, to date only little research exists on technological acceptance and media use in this age-group especially for cognitively-impaired seniors. Therefore, in order to assess specific preferences and potential barriers of older adults regarding a web-based platform for cognitive training, we conducted qualitative interviews with 12 older adults. Half of the participants were diagnosed with mild cognitive impairment (MCI). Most importantly, our results show that cognitive exercises should incorporate themes and topics older adults are interested in. Additional communication features could serve as ideal methods for increasing user motivation. Furthermore, we derived eight critical requirements of older adults concerning daily use of a web-based cognitive training platform. Implications for future research and development are discussed.

    Whereas the smoking prevalence rates in the general population are declining, rates among people diagnosed with attention-deficit/hyperactivity disorder (ADHD) continue to be elevated. Previous research has shown that nicotine may improve attention and mood, suggesting that nicotine may help ameliorate the attentional and emotional problems associated with ADHD. The present study examined the effects of nicotine with and without stimulant medication on ADHD symptoms, moods, and arousal in the everyday lives of smokers with ADHD. A total of 10 smokers with ADHD who were being treated with stimulant medication were asked to abstain from smoking while participating in the study. Participants underwent four conditions in randomized order: (a) Nicotine patch+stimulant medication, (b) nicotine patch only, (c) placebo patch+stimulant medication, and (d) placebo patch only. Each condition continued for 2 days, during which self-reports of ADHD symptoms and moods were obtained using electronic diaries. Lightweight ambulatory monitors recorded cardiovascular activity at each diary entry. Smoking abstinence was verified by expired carbon monoxide and salivary cotinine analysis. Results showed that nicotine patches and stimulant medication alone and in combination reduced difficulty concentrating and core ADHD symptoms compared with placebo patch only. Borderline improvement in impatience and self-control was seen with nicotine patch administration primarily on day 1. Nicotine patches also tended to elevate systolic and diastolic blood pressure compared with placebo patch during day 2. The findings suggest that smokers with ADHD experience nicotine-related reductions in ADHD symptoms during their everyday lives.

  8. Treating Attention-Deficit/Hyperactivity Disorder in Adults: Focus on Once-Daily Medications

    Objective: To review the efficacy, safety, and abuse liability of approved treatments in adults with attention-deficit/hyperactivity disorder (ADHD), with a focus on once-daily medications. Data Sources: PubMed was searched for relevant studies/reviews in English from 2002 to 2011 on adult ADHD treatments. Study Selection: Keywords used in the search were ADHD, adults, and treatment. Limits included only clinical trials, meta-analyses, randomized controlled trials, and reviews including adults (aged ≥ 19 years). Data Extraction: Selection criteria returned 471 publications. Retrieved studies were excluded if they primarily focused on children, treatments not indicated for ADHD, or ADHD and comorbid conditions. Data Synthesis: An epidemiologic survey revealed that 10.9% of adults identified with ADHD had received treatment during the prior 12 months. Treatments for ADHD in adults include pharmacologic and nonpharmacologic options. US Food and Drug Administration–approved long-acting stimulants and a nonstimulant with proven efficacy and safety profiles have been developed and include osmotic-release oral system methylphenidate hydrochloride (OROS-methylphenidate), extended-release dexmethylphenidate hydrochloride, mixed amphetamine salts extended release (MAS-XR), the nonstimulant atomoxetine hydrochloride, and the prodrug lisdexamfetamine dimesylate. Long-acting stimulants differ in formulation characteristics used to achieve extended release, with OROS-methylphenidate employing an osmotic-release technology, extended-release dexmethylphenidate hydrochloride and MAS-XR using pH-dependent beads, and lisdexamfetamine dimesylate using prodrug technology. These features variably affect pharmacokinetic characteristics, duration of action, and abuse liability. While all long-acting medications have varied pharmacokinetic features, mechanism of action, and duration of effect, all are generally efficacious and safety profiles are similar. Conclusion: Approved long

    Guided by the extended parallel process model (EPPM) and reactance theory, this study examined the relationship between efficacy beliefs, reactance, and adult smokers' responses to pictorial health warning labels (HWL) on cigarette packaging, including whether efficacy beliefs or reactance modify the relationship between HWL responses and subsequent smoking cessation behavior. Four waves of data were analyzed from prospective cohorts of smokers in Australia and Canada (n = 7,120 observations) over a period of time after implementation of more prominent, pictorial HWLs. Three types of HWL responses were studied: psychological threat responses (i.e., thinking about risks from smoking), forgoing cigarettes due to HWLs, and avoiding HWLs. The results from Generalized Estimating Equation models indicated that stronger efficacy beliefs and lower trait reactance were significantly associated with greater psychological threat responses to HWLs. Similar results were found for models predicting forgoing behavior, although response efficacy was inversely associated with it. Only response efficacy was significantly associated with avoiding HWLs, showing a positive relationship. Higher self-efficacy and stronger responses to HWLs, no matter the type, were associated with attempting to quit in the follow-up period; reactance was unassociated. No statistically significant interactions were found. These results suggest that stronger efficacy beliefs and lower trait reactance are associated with some stronger responses to fear-arousing HWL responses; however, these HWL responses appear no less likely to lead to cessation attempts among smokers with different levels of self-efficacy to quit, of response efficacy beliefs, or of trait reactance against attempts to control their behavior.

    Older adults with cognitive impairment often have difficulties in remembering the proper sequence of activities of daily living (ADLs) or how to use the tools necessary to perform ADLs. They, therefore, require reminders in a timely fashion while performing ADLs. This is a very stressful situation for the caregivers of people with dementia. In this paper we describe a pilot study where a tele-operated assistive robot helps a group of older adults with dementia (OAwD) to perform an ADL, namely making a cup of tea in the kitchen. Five OAwD along with their caregivers participated in this study which took place in a simulated-home setting. The purpose of this study was to investigate the feasibility and usability of a robotic system in assisting the OAwD to perform ADL in a home setting. The findings from this study will contribute to achieve our ultimate goal of designing a full-fledged assistive robot that assists OAwD aging in their own homes. The assistive robots designed for people with dementia mostly focus on companionship. This is, to the best of our knowledge, the first attempt to design an assistive robot which will provide step-by-step guidance to people with dementia in their activities of daily living.

    Recent research has suggested that marijuana use is associated with volumetric and shape differences in subcortical structures, including the nucleus accumbens and amygdala, in a dose-dependent fashion. Replication of such results in well controlled studies is essential to clarify the effects of marijuana. To that end, this retrospective study examined brain morphology in a sample of adult daily marijuana users (n = 29) versus nonusers (n = 29) and a sample of adolescent daily users (n = 50) versus nonusers (n = 50). Groups were matched on a critical confounding variable, alcohol use, to a far greater degree than in previously published studies. We acquired high-resolution MRI scans, and investigated group differences in gray matter using voxel-based morphometry, surface-based morphometry, and shape analysis in structures suggested to be associated with marijuana use, as follows: the nucleus accumbens, amygdala, hippocampus, and cerebellum. No statistically significant differences were found between daily users and nonusers on volume or shape in the regions of interest. Effect sizes suggest that the failure to find differences was not due to a lack of statistical power, but rather was due to the lack of even a modest effect. In sum, the results indicate that, when carefully controlling for alcohol use, gender, age, and other variables, there is no association between marijuana use and standard volumetric or shape measurements of subcortical structures.

    Although it has been proposed that trace minerals have anti-oxidative functions and are related to the control of blood pressure, only a limited number of studies directly address the issue. Thus, the purpose of our study was to assess the intake of copper and manganese, which are trace minerals, and to clarify their relation to blood pressure. In a cross-sectional study, the blood pressure of 640 normotensive adults, from 19 to 69 year-old (320 males and 320 females), was measured, and its correlation with the intake of copper and manganese was assessed using a 24-hour dietary recall method. The average value of the blood pressure was 126.4/80.2 mmHg for the males and 117.8/75.8 mmHg for the females. The daily copper intake was 1.3 mg/day for the males and 1.2 mg/day for the females. For manganese, the daily intake was 4.2 mg/day for the males and 4.1 mg/day for the females. Although the copper intake of all subjects showed a positive correlation with the systolic and diastolic blood pressures, there was no significant correlation when the potential confounding factors were adjusted. The manganese intake of the male subjects had a significantly negative correlation with the systolic blood pressure after adjusting for gender, age, body mass index, and energy intake. In conclusion, the daily manganese intake of the normotensitve adults showed a significantly negative correlation with the systolic blood pressure indicating a possibility of a positive effect of manganese on blood pressure.

    Rationale. To date no state-of-the-art clinical study has been conducted to address the question as to whether switching to lower tar cigarettes reduces exposure to smoke constituents in humans. Methods. Randomized, controlled, forced switching study in 225 adult smokers of full flavor Marlboro (MFF) cigarettes for 8 days with a 24-week follow-up. Subjects smoked MFF (a 15-mg Federal Trade Commission (FTC) tar cigarette) at baseline and were randomized to smoke 11-mg Marlboro Lights (ML) or 6-mg Marlboro Ultra Lights (MUL) cigarettes. Biomarkers of exposure to nicotine, 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), pyrene, CO, benzene, acrolein, and mutagenic substances were measured. Results. In the short-term phase, switching from MFF to ML showed statistically significant decreases in nicotine exposure (-13%) and non-significant increases in CO exposure (+6%), while switching from MFF to MUL showed statistically significant decreases in nicotine (-27%) and CO (-13%) exposure. Both nicotine and CO biomarkers trended similarly in the 24-week follow-up as in the short-term phase. The other biomarkers of cigarette smoke constituents followed the same trend as nicotine at the end of the 24-week follow-up. Conclusions. Switching smokers to lower FTC tar yield cigarettes, on average, reduces nicotine and other biomarkers considered surrogates of tar exposure. PMID:18565634

    The aim of this study is to estimate dietary intake of benzoic acid and its salts through food additives in adult population of South East Serbia. Information on dietary intake among 620 adults (aged 18-65) was collected using a food frequency questionnaire, and 748 food samples were analyzed. The mean estimated intake of benzoic acid -0.32 mg/kg of body weight (bw) per day was below acceptable daily intake (ADI). Dietary exposure to benzoic acid (0.36 mg/kg of bw/day; 7.2% ADI) (consumer only), also did not exceed ADI. The main contributors of benzoic acid to dietary intake were non alcoholic beverages (43.1%), ketchup and tomato products (36.1%), and domestic pickled vegetables (19.4%). The results of this study indicate that dietary exposure to benzoic acid and its salts through food preservatives does not represent a public health risk for the adult population of South East Serbia.

    Background to the debate Tobacco continues to kill millions of people around the world each year and its use is increasing in some countries, which makes the need for new, creative, and radical efforts to achieve the tobacco control endgame vitally important. One such effort is discussed in this PLOS Medicine Debate, where Simon Chapman presents his proposal for a “smoker's license” and Jeff Collin argues against. Chapman sets out a case for introducing a smart card license for smokers designed to limit access to tobacco products and encourage cessation. Key elements of the smoker's license include smokers setting daily limits, financial incentives for permanent license surrender, and a test of health risk knowledge for commencing smokers. Collin argues against the proposal, saying that it would shift focus away from the real vector of the epidemic—the tobacco industry—and that by focusing on individuals it would censure victims, increase stigmatization of smokers, and marginalize the poor.

    Introduction Alternative Nicotine Delivery Systems (ANDS) such as e-cigarettes are battery-powered devices that aerosolize nicotine and other substances to simulate smoking without using tobacco. Little is known about the ANDS initiation process among adult smokers. The aims of this research are threefold to: (1) examine how ANDS use affects cigarette use; (2) examine how the immediate environmental and psychosocial contexts of cigarette and ANDS use vary within—and between—participants in general and by menthol preference and race; and, (3) examine participants' ‘lived experience’ of the subjective perceptions, meaning, influences and utility of cigarette and ANDS use. Methods and analyses This study's mixed method, 6-week longitudinal design will produce a detailed description of the ANDS initiation process among adult smokers (N=100). Qualitative and quantitative data collection will include 3 weeks of: (1) ecological momentary assessment of patterns of cigarette/ANDS use, satisfaction, mood and craving; (2) geospatial assessment of participants' environment, including indoor and outdoor cigarette/ANDS norms and rules; (3) in-depth interviews about the meaning and utility of cigarette smoking and ANDS use; and, (4) saliva cotinine and exhaled carbon monoxide (CO) biomarkers. A diverse sample will be recruited with an equal number of menthol and non-menthol cigarette smokers. As the primary independent variable, we will investigate how ANDS use affects cigarette consumption. We will also examine how smoking-related and ANDS-related rules and norms surrounding product use influence cigarette and ANDS product use, and how the subjective effects of ANDS use affect ANDS perceptions, beliefs and use. Ethics and dissemination This study was funded by the National Institute on Drug Abuse of the US National Institutes of Health (1R21DA036472), registered at ClinicalTrials.gov (NCT02261363), and approved by the Chesapeake IRB (Pro00008526).

    Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. The prevalence of COPD among cigarette smokers in the Middle East is not well studied. A prospective descriptive study was performed in the north of Jordan. Male cigarette smokers (≥ 10 pack-year) aged 35 years and older were recruited from the community. They completed a questionnaire and a postbronchodilator spirometry. Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria (postbronchodilator forced expiratory volume in 1 second <70%) was used to define COPD. A total of 512 subjects completed the study protocol. According to the GOLD criteria, 42 subjects (8.2%) had COPD. Of those, 27 subjects (64.3%) had symptomatic COPD. Using the GOLD criteria, eight subjects (19%) with COPD had mild disease, 24 (57.1%) had moderate disease, eight (19%) had severe disease, and two (4.8%) had very severe disease. Only 10.6% were aware of COPD as a smoking-related respiratory illness, and 6.4% had received counseling about risk for COPD by a physician. Chronic bronchitis (cough for 3 months in 2 consecutive years) was reported by 15% of the subjects, wheezes by 44.1%, and dyspnea by 65.2%. Subjects with COPD reported having more chronic bronchitis 18/42 (42.9%) and wheezing 28/42 (66.7%) than subjects without COPD. The prevalence of COPD increased with increased number of pack-years smoked. In conclusion, COPD prevalence among cigarette-smoking men in Jordan is lower than in the developed world. COPD was largely underdiagnosed, despite the majority of participants being symptomatic and having moderate to severe disease.

    A best evidence topic was constructed according to a structured protocol. The question addressed was whether daily routine (DR) chest radiographs (CXRs) are necessary after pulmonary surgery in adult patients. Of the 66 papers found using a report search, seven presented the best evidence to answer the clinical question. Four of these seven studies specifically addressed post-cardiothoracic adult patients. Three of these seven studies addressed intensive care unit (ICU) patients and included post-cardiothoracic adult patients in well-designed studies. Six of these seven studies compared the DR CXRs strategy to the clinically indicated, on-demand (OD) CXRs strategy. Another study analysed the clinical impact of ceasing to perform the DR, postoperative, post-chest tubes removal CXRs. The authors, journal, date and country of publication, study type, group studied, relevant outcomes and results of these papers are given. We conclude that, on the whole, the seven studies are unanimously in favour of forgoing DR CXRs after lung resection and advocate OD CXRs. One study suggested that hypoxic patients could benefit from a DR CXRs strategy, while other studies failed to identify any subgroup for whom performing DR CXRs was beneficial. Indeed, DR CXRs, commonly taken after thoracic surgery, have poor diagnostic and therapeutic value. Eliminating them for adult patients having undergone thoracic surgery significantly decreases the number of CXRs per patient without increasing mortality rates, length of hospital stays (LOSs), readmission rates and adverse events. Hence, current evidence shows that DR CXRs could be forgone after lung resection because OD CXRs, recommended by clinical monitoring, have a better impact on management and have not been proved to negatively affect patient outcomes. Moreover, an OD CXRs strategy lowers the cost of care. Nevertheless, an OD CXRs strategy requires close clinical monitoring by experienced surgeons and dedicated intensivists. However

    Alcohol abuse among adolescents continues to be a major health problem for our society. Our laboratory has used the peri-adolescent alcohol-preferring, P, rat as an animal model of adolescent alcohol abuse. Even though peri-adolescent P rats consume more alcohol (g/kg/day) than their adult counterparts, it is uncertain whether their drinking is sufficiently aggregated to result in measurable blood ethanol concentrations (BECs). The objectives of this study were to examine daily alcohol drinking patterns of adolescent and adult, male and female P rats, and to determine whether alcohol drinking episodes were sufficiently aggregated to result in meaningful BECs. Male and female P rats were given 30 days of 24 h free-choice access to alcohol (15%, v/v) and water, with ad lib access to food, starting at the beginning of adolescence (PND 30) or adulthood (PND 90). Water and alcohol drinking patterns were monitored 22 h/day with a "lickometer" set-up. The results indicated that (a) peri-adolescent P rats consumed more water and total fluids than adult P rats, (b) female P rats consumed more water and total fluids than male P rats, (c) there were differences in alcohol, and water, licking patterns between peri-adolescent and adult and female and male P rats, (d) individual licking patterns revealed that alcohol was consumed in bouts often exceeding the amount required to self-administer 1 g/kg of alcohol, and (e) BECs at the end of the dark cycle, on the 30th day of alcohol access, averaged 50 mg%, with alcohol intakes during the last 1 to 2 h averaging 1.2 g/kg. Overall, these findings indicate that alcohol drinking patterns differ across the age and sex of P rats. This suggests that the effectiveness of treatments for reducing excessive alcohol intake may vary depending upon the age and/or sex of the subjects being tested.

    Introduction There is evidence that greater neighbourhood walkability (i.e., neighbourhoods with more amenities and well-connected streets) is associated with higher levels of total walking in Europe and in Asia, but it remains unclear if this association holds in the Canadian context and in chronic disease populations. We examined the relationships of different walkability measures to biosensor-assessed total walking (i.e., steps/day) in adults with type 2 diabetes living in Montreal (QC, Canada). Materials and Methods Participants (60.5±10.4 years; 48.1% women) were recruited through McGill University-affiliated clinics (June 2006 to May 2008). Steps/day were assessed once per season for one year with pedometers. Neighbourhood walkability was evaluated through participant reports, in-field audits, Geographic Information Systems (GIS)-derived measures, and the Walk Score®. Relationships between walkability and daily steps were estimated using Bayesian longitudinal hierarchical linear regression models (n = 131). Results Participants who reported living in the most compared to the least walkable neighbourhoods completed 1345 more steps/day (95% Credible Interval: 718, 1976; Quartiles 4 versus 1). Those living in the most compared to the least walkable neighbourhoods (based on GIS-derived walkability) completed 606 more steps per day (95% CrI: 8, 1203). No statistically significant associations with steps were observed for audit-assessed walkability or the Walk Score®. Conclusions Adults with type 2 diabetes who perceived their neighbourhoods as more walkable accumulated more daily steps. This suggests that knowledge of local neighborhood features that enhance walking is a meaningful predictor of higher levels of walking and an important component of neighbourhood walkability.

    The relationships between aspects of daily life-style and age, level of education, and body mass index (BMI; weight/height) were studied in young adult males (n = 1765) and females (n = 2092) in three age groups (19-21, 24-26 and 29-31 yr) in a Dutch population. By means of principal-components analysis five conceptually meaningful factors could be distinguished within the aspects of daily life-style which were considered. These factors were interpreted as constructs of: (1) slimming behaviour; (2) behaviour characterized by the consumption of coffee and alcohol, smoking habits and the number of hours sleep per night (CASS behaviour); (3) eating sweet and savoury snacks between meals; (4) health-conscious behaviour; and (5) physical activity. After adjustments were made for age and level of education, multiple regression analysis showed that slimming behaviour was positively related to BMI in both sexes, CASS behaviour was positively related to BMI in males, and health-conscious behaviour was inversely related to BMI in both sexes. An observed positive relationship between BMI and occupational physical activity in males could be explained by a confounding effect of socio-economic status. The observed weak positive relationship between number of hours active sport per month and BMI in males is possibly due to a difference in lean body mass. The consumption of sweet and savoury snacks was not related to BMI in either sex. These findings suggest that the daily life-style variables should be interpreted as indicators of more general types of behaviour, some of which may be important determinants of obesity.

    Introduction: The present study characterizes the tobacco use, quitting behaviors, and health characteristics of cigarette smokers who did not change their smoking pattern over the past 6 months and have used electronic cigarettes (ECs) in the past 30 days. This is an important subpopulation to characterize if EC dual use with cigarettes continues to grow. Methods: Participants (N = 2,376) from a research survey panel completed an online cross-sectional survey between June and August 2012. Sampling was stratified to recruit equal numbers of cigarette smoking participants by race/ethnicity (Black, Hispanic, and Caucasian) and smoking frequency (nondaily and daily). All displayed a stable rate of smoking for the past 6 months and were not currently in treatment. Bivariate and multivariate analyses were used to examine correlates of current EC use (any use within the past 30 days). Results: Current EC use was reported by 9.2% (n = 219) of the total sample. Of current EC users, 44% reported having used ECs as a quit method. Bivariate and multivariate analyses showed that current EC use was significantly associated with greater nicotine dependence, concurrent poly-tobacco use, more past-year quit attempts, past use of multiple cessation methods, and more depressive symptoms. No demographic variables were significantly associated with current EC use. Conclusions: This study suggests that stable smokers who currently use ECs possess characteristics that are associated with difficulty in achieving smoking cessation. These characteristics should be considered when examining the effectiveness of ECs on cessation and in designing future cessation trials using ECs. PMID:25385875

    Changes in fifteen urine, blood and exhaled breath BoEs of HPHCs representing classes of compounds reported by FDA to be significant contributors to smoking-associated disease risks were measured in 105 clinical-confined subjects following randomization and a five-day forced-switch from usual brand conventional combustible cigarettes to: (i) exclusive commercial e-cigarette use; (ii) dual-use of commercial e-cigarettes and the subject's usual cigarette brand; or (iii) discontinued use of all tobacco or nicotine products. Levels of urinary biomarkers in subjects that completely substituted their usual cigarette with e-cigarettes were significantly lower (29-95%) after 5 days. Percent reductions in eight of nine urinary BoEs were indistinguishable to smokers who had quit smoking, except for nicotine equivalents, which declined by 25-40%. Dual users who halved self-reported daily cigarette consumption with e-cigarettes exhibited reductions (7-38%) in eight of nine urinary biomarkers, but had increase (1-20%) in nicotine equivalents. Reductions were broadly proportional to the reduced numbers of cigarettes smoked. Dual user urinary nicotine equivalents were slightly higher, but not statistically significant. After 5 days, blood nicotine biomarker levels were lower in the cessation (75-96%) and exclusive use groups (11-83%); with dual users experiencing no significant reductions. All subjects experienced significant decreases in exhaled CO. Decreases in the cessation and exclusive groups ranged from 88-89% and 27-32% in dual users. Exhaled NO increased in the cessation and exclusive groups (46-63% respectively), whereas the dual users experienced minimal changes. Overall, smokers who completely or partially substituted conventional cigarettes with e-cigarettes over five days, experienced reductions in HPHCs. PMID:27401591

    Although social deficits remain a persistent component of the behavioural phenotype of Pervasive Developmental Disorders (PDD) in adulthood, it remains unclear whether these represent diminished social needs, as is seen in social anhedonia, or rather thwarted social needs, as is seen in social anxiety. This study used the Experience Sampling Method (ESM)--a structured diary technique--to examine social interaction in daily life of 8 adults with PDD, compared to 14 healthy controls. Multilevel linear regression analyses showed that PDD subjects a) did not spend more time alone, b) had no increased preference to be alone when in company, and c) spent more time with familiar people, compared to control subjects. Patients experienced more negative affect and anxiety when in the company of less familiar people compared to when they are alone, whereas no difference in affect could be found between being alone or being with familiar people. All these lines of evidence suggest that PDD subjects do have a desire to interact. However, this may be thwarted as is seen in social anxiety. Therapeutic interventions should aim at decreasing negative affect and anxiety in social interactions possibly by improving social skills to fulfil the existing social needs in adults with PDD.

    Light and intermittent smoking has become a prevalent pattern of use among young adults. Little is known about which factors differentiate light and intermittent smokers (LITS) from heavy smokers (HS) in young adulthood. In this study, we compare young adult LITS with HS with regard to demographic- and smoking-related variables, self-control abilities, and concrete strategies of smoking restraint. The data were collected as part of an Ecological Momentary Assessment (EMA) study with 137 German young adult smokers (M Age = 21.1 years, 46.0% female; 76 HS [≥10 cigarettes/day] and 61 LITS [≤5 cigarettes/day]). Participants were recruited over the Internet and completed a baseline questionnaire online. Several variables differentiated LITS and HS in a multiple logistic regression analysis: LITS reported fewer smoking friends (p < .001) and a higher self-efficacy to resist smoking (p < .01). Further, LITS smoking status was associated with reporting a past quit attempt (p < .05) and the use of smoking restraint strategies (counting, limiting, and purposefully not smoking cigarettes; p < .05). Notably, nicotine dependence and trait self-control abilities did not differentiate between LITS and HS. Our results point to the role of smoking restraint strategies and self-monitoring of smoking to limit the daily number of cigarettes smoked.

    Objective Some researchers have raised concerns that pictorial health warning labels (HWLs) on cigarette packages may lead to message rejection and reduced effectiveness of HWL messages. This study aimed to determine how state reactance (i.e., negative affect due to perceived manipulation) in response to both pictorial and text-only HWLs is associated with other types of HWL responses and with subsequent cessation attempts. Methods Survey data were collected every 4 months between September 2013 and 2014 from online panels of adult smokers in Australia, Canada, Mexico, and the US were analyzed. Participants with at least one wave of follow-up were included in the analysis (n = 4,072 smokers; 7,459 observations). Surveys assessed psychological and behavioral responses to HWLs (i.e., attention to HWLs, cognitive elaboration of risks due to HWLs, avoiding HWLs, and forgoing cigarettes because of HWLs) and cessation attempts. Participants then viewed specific HWLs from their countries and were queried about affective state reactance. Logistic and linear Generalized Estimating Equation (GEE) models regressed each of the psychological and behavioral HWL responses on reactance, while controlling for socio-demographic and smoking-related variables. Logistic GEE models also regressed having attempted to quit by the subsequent survey on reactance, each of the psychological and behavioral HWL responses (analyzed separately), adjustment variables. Data from all countries were initially pooled, with interactions between country and reactance assessed; when interactions were statistically significant, country-stratified models were estimated. Results Interactions between country and reactance were found in all models that regressed psychological and behavioral HWL responses on study variables. In the US, stronger reactance was associated with more frequent reading of HWLs and thinking about health risks. Smokers from all four countries with stronger reactance reported greater

    Daily affect is important to health and has been linked to cortisol. The combination of high negative affect and low positive affect may have a bigger impact on increasing HPA axis activity than either positive or negative affect alone. Financial strain may both dampen positive affect as well as increase negative affect, and thus provides an excellent context for understanding the associations between daily affect and cortisol. Using random effects mixed modeling with maximum likelihood estimation, we examined the relationship between self-reported financial strain and estimated mean daily cortisol level (latent cortisol variable), based on six salivary cortisol assessments throughout the day, and whether this relationship was mediated by greater daily negative to positive affect index measured concurrently in a sample of 776 Coronary Artery Risk Development in Young Adults (CARDIA) Study participants. The analysis revealed that while no total direct effect existed for financial strain on cortisol, there was a significant indirect effect of high negative affect to low positive affect, linking financial strain to elevated cortisol. In this sample, the effects of financial strain on cortisol through either positive affect or negative affect alone were not significant. A combined affect index may be a more sensitive and powerful measure than either negative or positive affect alone, tapping the burden of chronic financial strain, and its effects on biology.

    ABSTRACT Guided by the extended parallel process model (EPPM) and reactance theory, this study examined the relationship between efficacy beliefs, reactance, and adult smokers’ responses to pictorial health warning labels (HWL) on cigarette packaging, including whether efficacy beliefs or reactance modify the relationship between HWL responses and subsequent smoking cessation behavior. Four waves of data were analyzed from prospective cohorts of smokers in Australia and Canada (n = 7,120 observations) over a period of time after implementation of more prominent, pictorial HWLs. Three types of HWL responses were studied: psychological threat responses (i.e., thinking about risks from smoking), forgoing cigarettes due to HWLs, and avoiding HWLs. The results from Generalized Estimating Equation models indicated that stronger efficacy beliefs and lower trait reactance were significantly associated with greater psychological threat responses to HWLs. Similar results were found for models predicting forgoing behavior, although response efficacy was inversely associated with it. Only response efficacy was significantly associated with avoiding HWLs, showing a positive relationship. Higher self-efficacy and stronger responses to HWLs, no matter the type, were associated with attempting to quit in the follow-up period; reactance was unassociated. No statistically significant interactions were found. These results suggest that stronger efficacy beliefs and lower trait reactance are associated with some stronger responses to fear-arousing HWL responses; however, these HWL responses appear no less likely to lead to cessation attempts among smokers with different levels of self-efficacy to quit, of response efficacy beliefs, or of trait reactance against attempts to control their behavior.

    Background. Many older adults know about the health benefits of an active lifestyle, but, frequently, pain prevents them from engaging in physical activity. The majority of older adults experience pain, a complex experience that can vary across time and is shaped by sociocultural factors like gender. Objectives. To describe the time-varying associations between daily pain and physical activity and to explore differences in these associations between women and men. Methods. One hundred and twenty-eight community-dwelling older adults aged 65 years and older were asked to report their pain levels three times daily over a 10-day period and wear an accelerometer to objectively capture their daily physical activity (step counts and minutes of moderate to vigorous physical activity). Results. Increased daily step counts and minutes of moderate to vigorous physical activity were associated with increased daily pain, especially among women. Confirming past literature and contrasting findings for daily pain reports, overall pain levels across the study period were negatively associated with minutes of moderate to vigorous physical activity. Conclusions. Findings highlight that pain is significantly associated with physical activity in old age. The nature of this association depends on the time scale that is considered and differs between women and men. PMID:27445599

    Background Recent tax increases in Mexico differed in structure and provide an opportunity to better understand tobacco industry pricing strategies, as well as smokers’ responses to any resulting price changes. Objectives To assess if taxes were passed onto consumers of different cigarette brands, the extent of brand switching, and predictors of preference for cheaper national brands. Methods Using data from three waves of the Mexican administration of the ITC Survey, we analyzed self-reported brand and price paid at last cigarette purchase. Generalized estimating equations were used to determine predictors of price and preference for national brands. Results The average price of premium/international brands increased each year from 2008–2011; however, the price for discount/national brands increased only from 2010 to 2011. The percentage of smokers who smoked national brands remained stable between 2008 and 2010 but dropped in 2011. Factors related to smoking national as opposed to international brands included being male and having relatively older age, lower education, lower income, and higher consumption. Conclusions Tobacco industry pricing strategies in the wake of ad valorem taxes implemented in Mexico prior to 2011 had the impact of segmenting the market into discount national brands and premium international brands. The specific tax increase implemented in 2011 reduced the price gap between these two segments, by raising the price of the national brands relative to the international brands. Evidence for trading up was found after the 2011 tax increase. These results provide further evidence for the relevance of tax policy as a tobacco control strategy; in particular, they illustrate the importance of how specific rather than ad valorem taxes can reduce the potential for downward brand switching in the face of decreasing cigarette affordability.

    Studies have established that grown children's problems affect parental well-being, but a dearth of research has addressed daily interactions and biological systems that may underlie these associations. This study examined whether parents have different types of daily interactions with adult children who have problems and whether those interactions are associated with variations in parents' diurnal cortisol rhythms. Middle-aged parents (n=197) reported their interactions with adult children for seven consecutive days and provided saliva, analyzed for cortisol, three times a day (wake, 30 min after wake, bedtime) for four of those days. Parents were more likely to report negative encounters but not less likely to report positive interactions or contact with adult children who suffered from problems. Interactions with adult children who had physical-emotional problems had more immediate same day associations with cortisol whereas interactions with adult children who had lifestyle-behavioral problems had more delayed, or next day associations with cortisol. Daily interactions and their associations with the hypothalamic-pituitary-adrenal-axis may be important mechanisms by which adult children with problems negatively affect parental well-being.

    Objective To investigate the energy expenditure (EE) of Korean young adults based on activities refined to a deskbound lifestyle. Methods Sixty-four healthy office workers aged between 25 and 46 years participated in this study. EE was expressed as metabolic equivalent of task (MET). Participants were evaluated in terms of their EE during physical activities of sleeping (n=22), typing (n=37), folding laundry (n=34), dishwashing (n=32), studying (n=18), mopping (n=35), walking (n=33), stair climbing (n=23), and running (n=29). Volume of oxygen consumption was measured by indirect calorimetry K4b2 (COSMED). The results were compared to the established Compendium MET. Results The MET of activities were: sleeping, 1.24±0.43; typing, 1.35±0.25; folding laundry, 1.58±0.51; dishwashing, 2.20±0.51; studying, 2.11±0.90; mopping, 2.72±0.69; walking at 4 km/hr, 3.48±0.65; stair climbing of five stories, 6.18±1.08; and running at 8 km/hr, 7.57±0.57. The values of typing and mopping were similar to those in the Compendium, whereas those of sleeping, folding laundry, dishwashing, studying, walking, stair climbing and running were different. Conclusion To our knowledge, this estimation of EE in MET during activities of daily living is the first data of young adults in Korea. These data could be used as a reference to modify the guidelines of physical activities for the age group examined in this study. PMID:27606280

    2015-01-01

    Objectives. We examined loose cigarette (loosie) purchasing behavior among young adult (aged 18–26 years) smokers at bars in New York City and factors associated with purchase and use. Methods. Between June and December 2013, we conducted cross-sectional surveys (n = 1916) in randomly selected bars and nightclubs. Using multivariable logistic regression models, we examined associations of loose cigarette purchasing and use with smoking frequency, price, social norms, cessation behaviors, and demographics. Results. Forty-five percent (n = 621) of nondaily smokers and 57% (n = 133) of daily smokers had ever purchased a loosie; 15% of nondaily smokers and 4% of daily smokers reported that their last cigarette was a loosie. Nondaily smokers who never smoked daily were more likely than were daily smokers to have last smoked a loosie (odds ratio = 7.27; 95% confidence interval = 2.35, 22.48). Quitting behaviors and perceived approval of smoking were associated with ever purchasing and recently smoking loosies. Conclusions. Loosie purchase and use is common among young adults, especially nondaily smokers. Smoking patterns and attitudes should be considered to reduce loose cigarette purchasing among young adults in New York City. PMID:25880951

    2015-01-01

    The current study investigated 114 Native American young adults' experiences of racial microaggressions, and links between microaggression experiences and self-reported ethnic and cultural identification. Microaggressions were assessed using the Daily Racial Microaggressions Scale, Short Form (DRM). Ethnic identity and cultural participation were assessed using the Multigroup Ethnic Identity Measure (MEIM) and the Orthogonal Cultural Identification Scale (OCIS). Participants reported strong identification with their Native/indigenous ethnicity, along with stronger commitment than exploration on the 2 MEIM subscales. On the OCIS, participants reported moderately strong identification with Native culture and practices, with strong identification with White American culture. Females reported higher White identification than males, and females also reported significantly stronger identification with White culture than Native. On the DRM, 98% of participants reported experiencing at least 1 type of racial microaggression. Generally, the extent to which participants were upset by the microaggressions was mild, but all types of microaggressions received ratings from not upsetting at all to extremely upsetting. Microinvalidations were significantly more upsetting than microinsults for females, but there was no difference among the forms of microaggression for males. Correlational findings demonstrated that greater Native identification was strongly associated with more microaggression experiences, especially among males. Regression analyses found several identity correlates of microaggression experiences. "Assumption of criminality" and "assumed superiority of White values" were most frequently associated with identity scales. Results are discussed within the context of identity development theory.

    The aim was to identify and synthesize research evidence about how adults and older adults process somatosensory information in daily activities, and the interventions available to regain somatosensory function following stroke. We developed two interacting concept maps to address the research questions. The scoping review was conducted from 2005 to 2015 across Web of Science, AMED, CINAHL, Embase, Medline, and PsychInfo databases. Search terms included somatosensory, perception, performance, participation, older adult, stroke, intervention, discrimination, learning, and neuroplasticity. Contributions from 103 articles for Concept 1 and 14 articles for Concept 2 are reported. Measures of somatosensory processing, performance, and participation used are identified. Interventions available to treat somatosensory loss are summarized in relation to approach, outcome measures, and theory/mechanisms underlying. A gap exists in the current understanding of how somatosensory function affects the daily lives of adults. A multidisciplinary approach that includes performance and participation outcomes is recommended to advance the field.

    Existing survey data indicate that most smokers are not receptive to harm reduction incentives of switching to smokeless tobacco (SLT). Little is known about the underlying reasons for these views. To explore smokers' perceptions of SLT, we conducted a focus group (eight in total) study of daily smokers between 2009 and 2010 at the University of California, Irvine. We transcribed each 2-hour focus group verbatim and analyzed it using domain analysis. The discussions revealed several reasons why smokers are not receptive to SLT. First, smokers associated new spit-less SLT (that is, Snus) with historic images of chewing tobacco. Second, smokers viewed smoking as an incentive to take a break from their daily routine. Third, smokers expressed lack of control over nicotine delivery when using SLT, relative to cigarettes. These findings challenge tobacco manufacturers' strategies to market a smokeless alternative as a growing number of smoke-free policies are introduced.

    Growing evidence suggests that there are subpopulations of daily smokers ranging from light infrequent users to heavy daily users. In the present review we will investigate whether these differences can be explained by factors such as social context, responsiveness to environmental cues, personality traits, neurochemical and pharmacogenetic differences. We will also assess how controlled abstinence and free choice smoking paradigms in a human laboratory setting may help identify and characterize these differences and what can be learned from these models to accurately predict clinical efficacy in the later phase testing of new chemical entities for the treatment of smoking dependence.

    Given the increased prevalence of non-daily smoking and changes in smoking patterns, particularly among young adults, we examined correlates of smoking level, specifically motives for smoking, and readiness to quit smoking among 2682 college undergraduates who completed an online survey. Overall, 64.7% (n = 1736) were non-smokers, 11.6% (n = 312) smoked 1-5 days, 10.5% (n = 281) smoked 6-29 days and 13.2% (n = 353) were daily smokers. Ordinal regression analyses modeling smoking level indicated that correlates of higher smoking level included having more friends who smoke (β = 0.63, 95% CI 0.57-0.69) and more frequent other tobacco use (β = 0.04, 95% CI 0.02-0.05), drinking (β = 0.04, 95% CI 0.02-0.07) and binge drinking (β = 0.09, 95% CI 0.06-0.13). Bivariate analyses indicated that daily smokers (versus the subgroups of non-daily smokers) were less likely to smoke for social reasons but more likely to smoke for self-confidence, boredom, and affect regulation. Controlling for sociodemographics, correlates of readiness to quit among current smokers included fewer friends who smoke (P = 0.002), less frequent binge drinking (P = 0.03), being a social smoker (P < 0.001), smoking less for self-confidence (P = 0.04), smoking more for boredom (P = 0.03) and less frequent smoking (P = 0.001). Specific motives for smoking and potential barriers to cessation particularly may be relevant to different groups of college student smokers.

    Objectives We aimed to conduct culturally-based participatory research to assess cultural and belief contexts for smoking behaviours within Mandarin and Cantonese communities. Outcome variables were smoking-related knowledge, smoking patterns, attitudes and beliefs, and perceived barriers and facilitators to successful cessation. Design A community-based approach was applied involving smokers, community key-informants and professionals in study design and implementation. Initially, focus groups were conducted and findings were used to develop study instrument. Participants responded once to study questionnaire after informed consent. Setting Community based in the Greater Vancouver Area, Canada. Participants 16 Chinese smokers participated in focus groups and subsequently, 167 current Chinese immigrant (137 males and 30 females) smokers from Mandarin and Cantonese communities, recruited with the help of community agencies and collaborating physicians, were enrolled in a cross-sectional study. Results We found that a majority believed smoking was harmful on their health. Younger smokers (<35 years of age) did not mind smoking in front of young children compared to older smokers (≥35 years of age) (p<0.001). People with high school or lower levels of education believed that they would benefit more from smoking than suffering from withdrawal symptoms compared to better educated smokers (p<0.05). Mandarin smokers were significantly more likely to encourage others to quit than Cantonese smokers (p<0.05). Many indicated not receiving adequate support from care providers and lack of access to culturally and linguistically appropriate cessation programmes impacted on their ability to quit smoking. Conclusions Our study highlighted the importance of tobacco beliefs and perceptions among Mandarin and Cantonese speaking immigrants with limited access to healthcare information and for younger smokers whose attention to health consequences of smoking may be limited as

    Objective This study examined whether individual differences in loneliness and/or daily exacerbations in loneliness relate to daily pain and frequency and perception of interpersonal events among individuals with fibromyalgia (FM). Methods 118 participants with FM completed electronic diaries each evening for 21 days to assess the occurrence of positive and negative interpersonal events, event appraisals, and pain. Multilevel modeling was used to examine relations of chronic and transitory loneliness to daily life outcomes, controlling for daily depressive symptoms. Results Chronic and transitory loneliness were associated with more frequent reports of negative and less frequent reports of positive interpersonal daily events, higher daily stress ratings and lower daily enjoyment ratings, and higher daily pain levels. Neither chronic nor transitory loneliness moderated the relations between daily negative events and either stress appraisals or pain. However, both chronic and transitory loneliness moderated the relation between daily positive events and enjoyment appraisals. Specifically, on days of greater numbers of positive events than usual, lonely people had larger boosts in enjoyment than did nonlonely people. Similarly, days with greater than usual numbers of positive events were related to larger boosts in enjoyment if an individual was also experiencing higher than usual loneliness levels. Conclusions Chronic and transient episodes of loneliness are associated with more negative daily social relations and pain. However, boosts in positive events yield greater boosts in day-to-day enjoyment of social relations for lonely versus nonlonely individuals, and during loneliness episodes, a finding that can inform future interventions for individuals with chronic pain.

    Aims To accurately document the amount of quitting, length of quit attempts, and prevalence of plans and serious thought about quitting among smokers. Design We used longitudinal data from 7 waves of the International Tobacco Control Policy Evaluation 4-Country Survey (ITC-4). We considered point-prevalence data and cumulative prevalence over the 7 years of the study. We also derived annual estimates of quit activity from reports of quit attempts starting only within more recent timeframes, to control for biased recall. Setting Australia, Canada, the United Kingdom, and the United States of America. Participants 21 613 smokers recruited across 7 waves. Measurements Reported lifetime quit attempts, annual quit attempts, length of attempts, time since last attempt started, frequency of aborted attempts, plans to quit, and serious thought about quitting. Findings Around 40.1% (95% CI: 39.6-40.6) of smokers report attempts to quit in a given year and report an average of 2.1 attempts. Based on free recall, this translates to an average annual quit attempt rate of 0.82 attempts per smoker. Estimates derived only from the preceding month to adjust for recall bias indicate an annual rate of around 1 attempt per smoker. There is a high prevalence of quit-related activity, with over a third of smokers reporting thoughts or actions related to quitting in a given month. Over half the surveyed smokers eventually succeeded in quitting for at least 1 month, and a majority of these for over 6 months. Conclusions Smokers think a lot about stopping and make many unsuccessful quit attempts. Many have been able to last for extended periods and yet they still relapsed. More attention needs to be focussed on translating quit-related activity into long-term abstinence. PMID:21992709

    Young adults with an autism spectrum disorder (ASD) struggle to assume adult roles. This research assessed the feasibility of using the Adolescent and Young Adult Activity Card Sort (AYA-ACS) with emerging adults with high functioning ASD. Two phases were utilized during this research: (1) comparing the activity participation reported by emerging adults with an ASD and that reported by their caring adult; (2) examining the barriers to participation reported. Preliminary results demonstrate that the AYA-ACS appears to be a reliable and valid method of identifying emerging adults' participation strengths as well as personal and environmental challenges in a variety of age-appropriate activities. The AYA-ACS could assist service providers by providing an understanding of the challenges to participation faced by this population and aid in developing client centered interventions.

    Rural Australians are less physically active than their metropolitan counterparts, and yet very little is known of the candidate intervention targets for promoting physical activity in rural populations. As rural regions are economically, socially and environmentally diverse, drivers of regular physical activity are likely to vary between regions. This study explored the region-specific correlates of daily walking among middle age and older adults in rural regions with contrasting dominant primary industries. Participants were recruited through print and electronic media, primary care settings and community organisations. Pedometers were worn by 153 adults for at least four days, including a weekend day. A questionnaire identified potential intra-personal, social and environmental correlates of physical activity, according to a social ecological framework. Regression modelling identified independent correlates of daily walking separately in the two study regions. In one region, there were independent correlates of walking from all levels of the social ecological framework. In the other region, significant correlates of daily walking were almost all demographic (age, education and marital status). Participants living alone were less likely to be physically active regardless of region. This study highlights the importance of considering region-specific factors when designing strategies for promoting regular walking among rural adults. PMID:26761020

    In recent years, attempts have been made to incorporate religion into tobacco control efforts, especially in countries like Malaysia and Thailand where religion is central to the lives of people. This paper is a prospective examination of the perceived relevance and role of religion and religious authorities in influencing smoking behaviour among Muslims in Malaysia and Buddhists in Thailand. Data were collected from 1482 Muslim Malaysian and 1971 Buddhist Thai adult smokers who completed wave 1 (early 2005) of the International Tobacco Control Southeast Asia Survey (ITC-SEA). Respondents were asked about the role of religion and religious leadership on smoking at Wave 1 and among those recontacted, quitting activity at Wave 2. Results revealed that over 90% of both religious groups reported that their religion guides their day-to-day behaviour at least sometimes, but Malaysian Muslims were more likely to report that this was always the case. The majority (79% Muslims and 88% Buddhists) of both groups believed that their religion discourages smoking. About 61% of the Muslims and 58% of the Buddhists reported that their religious leaders had encouraged them to quit before and a minority (30% and 26%, respectively) said they would be an influential source to motivate them to quit. Logistic regression models suggest that these religious factors had a clear independent association with making quitting attempts in both countries and this translated to success for Malaysian Muslims but not for the Thai Buddhists. Taken together, results from this study indicate that religion and religious authorities are both relevant and important drivers of quitting, but whether this is always enough to guarantee success is less clear. Religion can be a culturally relevant vehicle to complement other tobacco control efforts.

    Background: Tobacco control has two aspects. One involves preventing non-tobacco users from using tobacco and the second involves tobacco cessation (quitting) by existing tobacco users. There are various methods of tobacco cessation. Pharmacotherapy [e.g., nicotine replacement therapy (NRT) and medications such as bupropion] and behavioral counselling are some of the internationally approved methods of tobacco cessation. Objective: This paper intends to study how age, gender, residence (rural/urban), education, and occupation influence the use of various tobacco cessation methods by smokers and smokeless tobacco users. Materials and Methods: The study was a cross-sectional secondary data analysis of the Global Adult Tobacco Survey (GATS) India 2009-2010. There were 3725 smokers and 6354 smokeless tobacco users included in the study who made attempts to quit in the 12 months prior to the survey by use of different cessation methods (NRT, drugs such as bupropion, counselling, and other methods). Results: A significant association was demonstrated between increasing educational attainment and use of cessation methods for all the methods among smokers. Being employed (Govt. or non-Govt.) was positively associated with the use of NRT as a cessation method by smokers. Students and homemakers had higher odds of using pharmacotherapy methods among smokers. A significant association was demonstrated for the gender and age of tobacco users with the use of counselling as a cessation method among smokeless tobacco users. Conclusion: The findings of this study have important implications for tobacco cessation service providers in view of supporting their decision of choosing a particular tobacco cessation method for tobacco users according to certain kinds of sociodemographic characteristics.

    Objective In order to assess the impact of educational content on students, this study investigated junior high school students' awareness of older adults' daily lives and the social resources available for older adults.Methods Participants were 967 second-year students at a public junior high school in S city. A complete enumeration survey was conducted using anonymous self-administered questionnaires. The survey items obtained information about participants' demographic characteristics, their perceptions of older adults' daily life, and their awareness of the social resources for older adults.Results Of the 555 returned questionnaires (57.4%), 490 (50.7%) valid responses were analyzed. A total of 158 participants (32.2%) lived with their grandparents, and 232 participants (47.3%) had some experience living with their grandparents, most of whom still lived independently. Further, 303 participants (61.8%) met their grandparents at least once or twice a week. The mean age of participants' grandparents was 72.2 years. The mean age that the participants regarded a person as "elderly" was 71.3 years. Participants' perceptions of older adults' daily lives included decreased physical ability due to aging, need and desire to stay in touch with family and/or friends, and enjoying hobbies and pleasurable activities. Participants who met their grandparents at least once or twice a week perceived elderly life as more cheerful compared to participants who met their grandparents once or twice a month or less. The participants were familiar with some social resources for older adults such as "administrative disaster-prevention wireless communication system," "transportation service by car," and "visiting nurse." Female participants were aware of significantly more social resources compared to male participants, as were participants who met their grandparents at least once or twice a week compared to those who met their grandparents once or twice a month or less

    Objective To assess the impact of wearing fixed orthodontic appliance (FOA) or clear-aligner, on daily performance in adult patients. Methods The Oral Impacts on Daily Performance (OIDP) index was assessed in 152 adults aged 25–35 years at baseline (T0), 6 months after bonding (T1), and 12 months after bonding (T2). Participants were randomly divided into two groups: CA group (participants treated with clear-aligner) and a control group (FOA group; participants treated with FOA). Baseline malocclusion severity was assessed using the Index of Orthodontic Treatment Need. Results There were no significant differences in sociodemographic variables and OIDP scores at baseline between the two groups. Significant changes in OIDP total and subscale scores were observed while wearing FOA: OIDP total score and subscale scores of eating, cleaning teeth, smiling, and social relation at T1 and T2 were significantly higher than at baseline (P<0.05 or P<0.01). However, only OIDP total score was significantly increased at T1 compared to the baseline in the CA group. OIDP total score and subscale scores of eating, cleaning teeth, smiling, and social relation were significantly higher in patients wearing FOA than in patients wearing clear-aligner at T1 and T2 (P<0.05 or P<0.01). Conclusion Patients wearing clear-aligner have fewer impacts on daily life than those wearing FOA during treatment, and have no significant changes in OIPD subscale scores at 12 months. FOA therapy significantly impacts daily performance in adult patients during treatment.

    It is unclear whether adult smokers with childhood attention-deficit/hyperactivity disorder history (CH) have more severe smoking behavior than non-CH smokers, while it is clearly suggested that CH adolescents have more severe smoking behavior than CH adolescents. The aim of the present comprehensive meta-analysis is to determine whether CH smokers have more severe smoking behavior characteristics than those without and the effect of age on the association between CH and smoking behavior. We included all case-control studies and first round data collection of observational studies addressing the difference in smoking behavior characteristics of CH smokers versus non-CH smokers, with validated scales or structured interviews, without any language or date restriction. Nine studies (including 365 smokers with CH and 1,708 smokers without) were included. Compared to non-CH smokers, CH smokers smoked significantly more cigarettes [standardized mean differences (SMD) = 0.15, 95 % CI 0.01-0.28, p = 0.04] and began to regularly smoke earlier (SMD = -0.28, 95 % CI -0.49; -0.07, p = 0.01) but were not significantly more nicotine dependent (SMD = 0.23, 95 % CI -0.04 to 0.48, p = 0.08). After removing the single adolescent study, the significant association between CH and number of daily smoked cigarettes disappeared, and subgroups analyses confirmed that the significant association between CH and number of daily smoked cigarettes disappeared as age increased. Our meta-analysis illustrates a clinically important link between CH and tobacco smoking in adolescence but not later in life. Further high-quality studies are needed to confirm this finding, as only two studies included participants with a mean age below 20 years.

  2. Effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers: a randomized controlled trial. ESPIROTAB study

    2011-01-01

    Background Undiagnosed airflow limitation is common in the general population and is associated with impaired health and functional status. Smoking is the most important risk factor for this condition. Although primary care practitioners see most adult smokers, few currently have spirometers or regularly order spirometry tests in these patients. Brief medical advice has shown to be effective in modifying smoking habits in a large number of smokers but only a small proportion remain abstinent after one year. The aim of this study is to evaluate the effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers. Methods/design Intervention study with a randomized two arms in 5 primary care centres. A total of 485 smokers over the age of 18 years consulting their primary care physician will be recruited. On the selection visit all participants will undergo a spirometry, peak expiratory flow rate, test of smoking dependence, test of motivation for giving up smoking and a questionnaire on socio-demographic data. Thereafter an appointment will be made to give the participants brief structured advice to give up smoking combined with a detailed discussion on the results of the spirometry. After this, the patients will be randomised and given appointment for follow up visits at 3, 6, 12 and 24 months. Both arms will receive brief structured advice and a detailed discussion of the spirometry results at visit 0. The control group will only be given brief structured advice about giving up smoking on the follow up. Cessation of smoking will be tested with the carbon monoxide test. Discussion Early identification of functional pulmonary abnormalities in asymptomatic patients or in those with little respiratory symptomatology may provide "ideal educational opportunities". These opportunities may increase the success of efforts to give up smoking and may improve the opportunities

    Introduction: Intermittent smokers (ITS) are an increasingly prevalent segment of smokers, yet it is unknown whether or how dependence severity may vary across ITS. Methods: Participants were 217 ITS (70 never daily ITS [NITS], 138 converted ITS [CITS], and 9 unknown), who smoked 4–27 days per month, and 197 daily smokers (DS), recruited for a study on smoking patterns. Participants completed questionnaires on dependence (time to first cigarette after waking, Fagerström Test of Nicotine Dependence [FTND], Nicotine Dependence Syndrome Scale [NDSS], Wisconsin Inventory of Smoking Dependence Motives [WISDM], and Hooked on Nicotine Checklist [HONC]) and recorded each cigarette in real time over 3 weeks using Ecological Momentary Assessment. Logistic regression assessed differences in dependence between groups (DS vs. ITS; CITS vs. NITS), and least squares regression examined associations between dependence and smoking behavior (mean, maximum cigarettes per day; proportion of days smoked; longest period of abstinence) within ITS. Results: As expected, DS were significantly more dependent than ITS: FTND, NDSS, and WISDM discriminated between ITS and DS with greater than 90% accuracy. Similarly, among ITS, NITS demonstrated lower dependence than CITS. Within ITS, dependence measures also correlated with observed smoking rate and duration of abstinence. Conclusions: The study confirmed that DS are more dependent than ITS and that CITS are more dependent than NITS. Importantly, ITS exhibit features of dependence, and there is meaningful variation in dependence within ITS, suggesting that some aspects of dependence may appear with very infrequent smoking. Future work should examine implications for ITS’ potential progression to daily smoking and cessation outcome. PMID:22529224

    Age-based self-stereotyping is associated with a variety of long-term physical health and psychological well-being outcomes for older people. However, little is known about how older individuals' day-to-day experiences of functional limitations may be related to concurrent self-appraisals on dimensions representing negative age stereotypes. We examined how distal personality traits and global self-perceptions of aging at baseline affect processing of daily experiences relevant to age-based self-stereotyping over time. Data from the 100-day Internet-based Personal Understanding of Life and Social Experiences (PULSE) study (N = 98, age = 52 - 88) were used to examine the link between personality and self-perceptions of aging to differences in 2 age stereotype-relevant daily experiences: cognitive limitations and variation in usefulness. Multilevel random coefficient models suggested that personality and self-perceptions of aging were associated with the level of usefulness and the frequency of reporting trouble concentrating during the study period. Daily experiences of trouble concentrating were significantly associated with lower perceived usefulness on that day, and conscientiousness moderated this relationship. By linking personality and global self-perceptions to daily experiences, our findings contribute toward understanding self-stereotyping processes by which personality and perceptions may affect long-term outcomes.

    Although there is a large amount of evidence that demonstrates the relationship between oral health status and oral impact daily performance, there are few studies that have evaluated the impact of prosthetic status, particularly the need for a dental prosthesis. Therefore, the aim of this study was to investigate the relationship between need and use of dental prostheses and the prevalence of oral impact on daily performance. A sample of 720 subjects, aged between 50 and 74 years, was evaluated using a cross-sectional study. Participants were selected through a multistage proportional random sampling. The impact of oral health status on daily performance (oral impact on daily performance--OIDP) and socio-demographic data was assessed using a standardised questionnaire, and clinical data were assessed by oral examination. The outcome was the prevalence of impact. The association between the explanatory variables and the outcome was analysed through two models of multivariate Poisson regression. In the adjusted model, the variables need of upper and lower prosthesis and use of lower prosthesis maintained a statistically significant association. No statistically relevant relation between socio-demographic variables and outcomes was found. Findings show that the need and use and of a prosthesis are related to oral health quality of life.

    Using online survey data from a large sample of adults with autism spectrum disorder (ASD) and legal guardians, we first report outcomes across a variety of contexts for participants with a wide range of functioning, and second, summarize these stakeholders' priorities for future research. The sample included n=255 self-reporting adults with ASD aged 18-71 years (M=38.5, SD=13.1), and n=143 adults with ASD aged 18-58 years (M=25.0, SD=8.2) whose information was provided by legal guardians. Although the self-reporting subsample had much higher rates of employment, marriage/partnership, and independent living than are typically seen in ASD outcome studies, they remained underemployed and had strikingly high rates of comorbid disorders. Data on both descriptive outcomes and rated priorities converged across subsamples to indicate the need for more adult research on life skills, treatments, co-occurring conditions, and vocational and educational opportunities. Stakeholders also placed priority on improving public services, health care access, and above all, public acceptance of adults with ASD. Findings must be interpreted in light of the self-reporting subsample's significant proportion of females and of later-diagnosed individuals. This study underscores the need for lifespan research; initiatives will benefit from incorporating information from the unique perspectives of adults with ASD and their families. PMID:25964655

  9. α-Tocopherol Supplementation Reduces 5-Nitro-γ-Tocopherol Accumulation By Decreasing γ-Tocopherol In Young Adult Smokers1

    γ-Tocopherol (γ-T) scavenges reactive nitrogen species (RNS) to form 5-NO2-γ-tocopherol (NGT). However, α-T supplementation decreases circulating γ-T, which could limit its RNS scavenging activities. We hypothesized that α-T supplementation would mitigate NGT accumulation by impairing γ-T status. Healthy smokers (21±1 y, n=11) and non-smokers (21±2 y, n=10) ingested 75 mg/d each of RRR- and all rac-α-tocopheryl acetate for 6 d. Plasma α-T, γ-T, γ-carboxyethyl-hydroxychromanol (CEHC), NGT, and nitrate/nitrite were measured prior to supplementation (Pre), the morning after 6 consecutive evenings of supplementation (Post 1), and on the mornings of d 6 (Post 6) and d 14 (Post 14) during the post-supplementation period. α-T supplementation increased plasma α-T, and decreased γ-T, in both groups and these returned to Pre concentrations on Post 6 regardless of smoking status. Plasma γ-CEHC increased after the first dose of supplementation in both groups, suggesting that α-T supplementation decreased plasma γ-T in part by increasing its metabolism. Plasma NGT and nitrate/nitrite at Pre were greater in smokers, indicating greater nitrative stress due to cigarette smoking. Plasma NGT was lowered only in smokers on Post 1 and Post 6 and was restored to Pre levels on Post 14. Plasma nitrate/nitrite tended (P=0.07) to increase post-supplementation only in smokers, supporting decreases in RNS scavenging by γ-T. Plasma NGT was more strongly correlated (P<0.05) with γ-T in smokers (R=0.83) compared to non-smokers (R=0.50), supporting that α-T-mediated decreases in γ-T reduces NGT formation. These data indicate that α-T supplementation limits γ-T scavenging of RNS in smokers by decreasing γ-T availability. PMID:25966030

  11. A single-blinded, single-centre, controlled study in healthy adult smokers to identify the effects of a reduced toxicant prototype cigarette on biomarkers of exposure and of biological effect versus commercial cigarettes

    PubMed Central

    2013-01-01

    Background Despite universal acceptance that smoking is harmful, a substantial number of adults continue to smoke. The development of potential reduced exposure products (more recently termed modified risk tobacco products) has been suggested as a way to reduce the risks of tobacco smoking. This trial is designed to investigate whether changes in toxicant exposure after switching from a commercial to reduced toxicant prototype (RTP) cigarette (7 mg International Organisation for Standardisation (ISO) tar yield) can be assessed by measurement of biomarkers and other factors. The primary objective is to descriptively assess changes in selected biomarkers of exposure (BoE) and biomarkers of biological effect (BoBE) within participants and within and between groups after switching. Secondary objectives are to assess similarly changes in other biomarkers, quality of life, smoking behaviours, physiological measures, mouth-level exposure to toxicants and sensory perception. Methods/design This trial will assess current smokers, ex-smokers and never-smokers in a single-centre single-blind, controlled clinical trial with a forced-switching design and in-clinic (residential) and ambulatory (non-residential) periods. Smokers will be aged 23–55 years (minimum legal smoking age plus 5 years) and non-smokers 28–55 years (minimum legal smoking age plus 5 years, plus minimum 5 years since last smoked). Smokers will be allowed to smoke freely at all times. We will assess changes in selected BoE and BoBE and effective dose in urine and blood after switching. Creatinine concentrations in serum, creatinine clearance in urine, cotinine concentration in saliva, diaries and collection of spent cigarette filters will be used to assess compliance with the study protocol. Mouth-level exposure to toxins will be assessed by filter analysis.

    Research on daily living activities and employment levels of adults with autism spectrum disorders (ASD) in Taiwan is limited. The aims of the study were to investigate outcomes related to functional independence and employment among people with ASD in Taiwan. We investigated the daily living activities and the employment status of 81 adults (age range, 18-48 years; mean age, 22.8 years) with ASD in southern Taiwan. Most (85.2%) participants with ASD were men, and all lived with their caregivers or guardians. Primary caregivers or guardians completed a self-administered, written questionnaire. More than three-quarters (80.2%) of the participants with ASD could independently take care of themselves. Instrumental activities of daily living they most frequently engaged in included walking outside for more than 15 min (88.9%), light housework (85.2%), and local shopping (80.2%). Only 11 (13.6%) of the participants with ASD were employed [five (6.2%) worked more than 20 h/week] and four (4.9%) were attending school. Types of occupation consisted of serving food and beverages, baking, and cleaning. Most (81.5%) of the participants with ASD were unemployed, stayed at home, and were cared for by family members. The results of this study provide information to support the design of adequate interventions to meet the needs of adults with ASD, particularly those in Taiwan. It is important to develop adequate interventions to facilitate the functional independence of this population. Future research using larger study populations with a comparison group is needed.

    Background This study analyzes Chicago-area weather effects on objectively measured physical activity over a three year period among a cohort of 241 participants in an on-going arthritis physical activity trial. Methods Uniaxial accelerometer counts and interview data were analyzed for up to six weekly study waves involving 4823 days of wear. The effects of temperature, rainfall, snowfall and daylight hours were analyzed after controlling for participant characteristics, day of the week, and daily accelerometer wear hours in a mixed effects linear regression model. Results Daylight hours, mean daily temperature <20 or ≥ 75 degrees and light or heavy rainfall (but not snowfall) were all significantly associated with lower physical activity after controlling for the significant effects of weekends, accelerometer wear hours, age, sex, type of arthritis, employment, Hispanic ethnicity, obesity, and SF36 physical and mental health scores. Conclusions The cumulative effects of weather are reflected in a 38.3% mean monthly difference in daily counts between November and June, reflecting over three additional hours of sedentary time. Physical activity promotion programs for older persons with chronic conditions need lifestyle physical activity plans adapted to weather extremes. PMID:21885884

  14. Could a scheme for licensing smokers work in Australia?

    PubMed

    Magnusson, Roger S; Currow, David C

    2013-08-01

    In this article, we evaluate the possible advantages and disadvantages of a licensing scheme that would require adult smokers to verify their right to purchase tobacco products at point of sale using a smart-card licence. A survey of Australian secondary school students conducted in 2011 found that half of 17-2013-old smokers and one-fifth of 12-2013-old smokers believed it was "easy" or "very easy" to purchase cigarettes themselves. Reducing tobacco use by adolescents now is central to the future course of the current epidemic of tobacco-caused disease, since most current adult smokers began to smoke as adolescents--at a time when they were unable to purchase tobacco lawfully. The requirement for cigarette retailers to reconcile all stock purchased from wholesalers against a digital record of retail sales to licensed smokers would create a robust incentive for retailers to comply with laws that prohibit tobacco sales to children. Foreseeable objections to introducing a smokers licence need to be taken into account, but once we move beyond the "shock of the new", it is difficult to identify anything about a smokers licence that is particularly offensive or demeaning. A smoker licensing scheme deserves serious consideration for its potential to dramatically curtail retailers' violation of the law against selling tobacco to minors, to impose stricter accountability for sale of a uniquely harmful drug and to allow intelligent use of information about smokers' purchases to help smokers quit.

    Cross-sectional research suggests that smokers are more impulsive than are non-smokers, but few studies have examined relations between impulsiveness and later success in quitting smoking. The purpose of this study was to investigate the reliability and predictive validity of facets of impulsiveness in adult smokers trying to quit. Baseline behavioral measures of impulsive choice (assessed with a delay discounting task) and impulsive action (assessed with a measure of behavioral disinhibition) were used as predictors of smoking cessation success over 12 weeks. The sample included 116 adult (18 years old or older) daily smokers from central New Jersey. Impulsive choice, impulsive action, and self-reported impulsiveness were not significantly related to one another at baseline. Impulsive choice had high test-retest reliability from pre- to post-quit, whereas impulsive action was less stable. Test-retest reliability from pre-quit to three weeks post-quit was moderated by achievement of seven-day abstinence. Baseline impulsive action was significantly negatively related to quitting for at least one day in the first two weeks of a quit attempt and of prolonged abstinence (no relapse over the next 10 weeks). Baseline impulsive choice was robustly associated with biochemically verified seven-day point-prevalence abstinence 12 weeks post-quit, such that those with lower delay discounting were more likely to achieve abstinence. Facets of impulsiveness appear to function largely independently in adult smokers, as indicated by their lack of inter-correlation, differential stability, and differential relations with abstinence. Impulsive action may impede initial quitting, whereas impulsive choice may be an obstacle to maintaining lasting abstinence. PMID:26751623

    Background This study’s aim was to clarify the relationship of having hobbies and a purpose in life (PIL; in Japanese, ikigai) with mortality and a decline in the activities of daily living (ADL) and instrumental ADL (IADL) among the community-dwelling elderly. Methods Prospective observational data from residents aged ≥65 years who were at increased risk for death (n = 1853) and developing a decline in ADL (n = 1254) and IADL (n = 1162) were analyzed. Cox proportional hazard models were used for mortality analysis of data from February 2011 to November 2014. ADL and IADL were evaluated using the Barthel Index and the Tokyo Metropolitan Institute of Gerontology Index of Competence, respectively. ADL and IADL were assessed at baseline and follow-up and were evaluated using logistic regression models. Fully adjusted models included terms for age, gender, BMI, income, alcohol intake, smoking history, number of chronic diseases, cognitive function, and depression. Results During the follow-up of eligible participants, 248 had died, 119 saw a decline in ADL, and 178 saw a decline in IADL. In fully adjusted models, having neither hobbies nor PIL was significantly associated with an increased risk of mortality (hazard ratio 2.08; 95% confidence interval [CI], 1.47–2.94), decline in ADL (odds ratio 2.74; 95% CI, 1.44–5.21), and decline in IADL (odds ratio 1.89; 95% CI, 1.01–3.55) compared to having both hobbies and PIL. Conclusions Although effect modifications by cognitive functioning and depression cannot be ruled out, our findings suggest that having hobbies and PIL may extend not only longevity, but also healthy life expectancy among community-dwelling older adults.

  18. Cognitive dissonance in tobacco smokers.

    PubMed

    McMaster, C; Lee, C

    The knowledge and beliefs about smoking of smokers, non-smokers, and ex-smokers were examined within a cognitive dissonance framework. The 186 respondents completed a questionnaire concerned with smoking habits, knowledge of the effects of smoking, beliefs about smoking, and estimates of risk of lung cancer to themselves and to the average Australian smoker. Smokers estimated their risk of contracting lung cancer as greater than the risk non-smokers or ex-smokers saw for themselves, but less than the risk for the average Australian smoker. No differences were found in the amount of factual knowledge about the effects of smoking. However, smokers endorsed significantly more rationalisations and distortions of logic regarding smoking than did non-smokers or ex-smokers. Smokers may experience cognitive dissonance as a result of using tobacco despite its well-publicised ill-effects, and it may be that interventions targeting rationalisations for smoking will be useful in smoking cessation.

    Aims: The aim of this study was to assess the effect of tobacco smoking on gingival health and the oral hygiene status of respondents. Materials and Methods: A cross-sectional survey of 213 adults from three communities in the Ibadan North local government was carried out. Respondents were divided into two groups comprising of 117 smokers (cases) and 96 non-smokers (control). Intra oral examination was done using the Simplified Oral Hygiene Index (OHI-S) and Gingival index (GI). Results: The mean age of the smokers was 31.2 ± 12.6 years and that of the non-smokers 32.8 ± 9.5 years. The mean Simplified Oral Hygiene Index (OHI-S) was 1.15 ± 0.51 for the non-smokers and 2.19 ± 0.62 for the smokers (P < 0.05). The mean GI was 1.06 ± 0.55 for the non-smokers and 1.62 ± 0.58 for the smokers (P < 0.05). Conclusion: The study shows that smoking is associated with increased severity of gingival disease. It is, therefore, recommended that smokers should be encouraged to visit a dentist for preventive procedure more regularly than the non-smokers and better still, smokers should be encouraged to quit smoking as gingival disease is not without consequences if allowed to persist.

    Mobile devices are a promising channel for delivering just-in-time guidance and support for improving key daily health behaviors. Despite an explosion of mobile phone applications aimed at physical activity and other health behaviors, few have been based on theoretically derived constructs and empirical evidence. Eighty adults ages 45 years and older who were insufficiently physically active, engaged in prolonged daily sitting, and were new to smartphone technology, participated in iterative design development and feasibility testing of three daily activity smartphone applications based on motivational frames drawn from behavioral science theory and evidence. An “analytically” framed custom application focused on personalized goal setting, self-monitoring, and active problem solving around barriers to behavior change. A “socially” framed custom application focused on social comparisons, norms, and support. An “affectively” framed custom application focused on operant conditioning principles of reinforcement scheduling and emotional transference to an avatar, whose movements and behaviors reflected the physical activity and sedentary levels of the user. To explore the applications' initial efficacy in changing regular physical activity and leisure-time sitting, behavioral changes were assessed across eight weeks in 68 participants using the CHAMPS physical activity questionnaire and the Australian sedentary behavior questionnaire. User acceptability of and satisfaction with the applications was explored via a post-intervention user survey. The results indicated that the three applications were sufficiently robust to significantly improve regular moderate-to-vigorous intensity physical activity and decrease leisure-time sitting during the 8-week behavioral adoption period. Acceptability of the applications was confirmed in the post-intervention surveys for this sample of midlife and older adults new to smartphone technology. Preliminary data exploring

    The specific components of airborne particulates responsible for adverse health effects have not been conclusively identified. We conducted a longitudinal study on 88 adult patients with chronic cough to evaluate whether exposure to daily ambient levels of particulate polycyclic aromatic hydrocarbons (PAH) has relationship with cough occurrence. Study participants were recruited at Kanazawa University Hospital, Japan and were physician-diagnosed to at least have asthma, cough variant asthma and/or atopic cough during 4th January to 30th June 2011. Daily cough symptoms were collected by use of cough diaries and simultaneously, particulate PAH content in daily total suspended particles collected on glass fiber filters were determined by high performance liquid chromatography coupled with fluorescence detector. Population averaged estimates of association between PAH exposure and cough occurrence for entire patients and subgroups according to doctor's diagnosis were performed using generalized estimating equations. Selected adjusted odds ratios for cough occurrence were 1.088 (95% confidence interval (CI): 1.031, 1.147); 1.209 (95% CI: 1.060, 1.379) per 1 ng/m3 increase for 2-day lag and 6-day moving average PAH exposure respectively. Likewise, 5 ring PAH had higher odds in comparison to 4 ring PAH. On the basis of doctor's diagnosis, non-asthma group had slightly higher odds ratio 1.127 (95% CI: 1.033, 1.228) per 1 ng/m3 increase in 2-day lag PAH exposure. Our findings suggest that ambient PAH exposure is associated with cough occurrence in adult chronic cough patients. The association may be stronger in non-asthma patients and even at low levels although there is need for further study with a larger sample size of respective diagnosis and inclusion of co-pollutants.

    Background Cigarette rod length as a design feature may play a specific role in harm perception and tobacco use. Internal tobacco industry documents have shown targeting of females with long/ultra-long cigarettes. This study assessed trends and differences in smoking of long/ultra-long cigarettes among U.S. smokers aged ≥20 years during 1999 through 2012. Methods Data were obtained from the 1999/2000 through 2011/2012 National Health and Nutrition Examination Survey. The proportion of current smokers who reported using long/ultra-long cigarettes during each survey year was calculated and compared using χ2 statistics. Linear and quadratic trends during 1999 through 2012 were assessed using binary logistic regression (p<0.05). Multi-variable analyses were performed to assess current disparities in smoking of long/ultra-long cigarettes. Results Despite overall declines in current smoking of long/ultra-long cigarettes during the 1999 through 2012 period (p<0.001 for both linear and quadratic trends), the proportion of smokers of long/ultra-long brands increased in recent years, with over a third (38.7%) of current smokers reporting smoking of long/ultra-long cigarettes during 2011/2012. Current smokers of long/ultra-long cigarettes were more likely to be female compared to males (aOR=3.09; 95%C.I:2.09–4.58), of black race compared to whites (aOR=2.07; 95%C.I:1.30–3.28), or aged 45–64, or ≥65 years (aOR=2.39 and 5.27 respectively), compared to 18–24 year olds. Conclusions Specific gender, age and race/ethnic characteristics of smokers of long/ultra-long cigarettes were noted, hence potentially contributing to the widening of health disparities. Cigarette rod length should be considered an important aspect of cigarette engineering/design in regulatory efforts to reduce the burden of tobacco-related disease. PMID:24417962

    This research examined the fundamental frequency and perturbation (jitter % and shimmer %) measures in young adult (20-30 year-old) and middle-aged adult (40-55 year-old) smokers and non-smokers; there were 36 smokers and 36 non-smokers. Acoustic analysis was carried out utilizing one task: production of sustained /a/. These voice samples were analyzed utilizing Multi-Dimensional Voice Program (MDVP) software, which provided values for fundamental frequency, jitter %, and shimmer %.These values were analyzed for trends regarding smoking status, age, and gender. Statistical significance was found regarding the fundamental frequency, jitter %, and shimmer % for smokers as compared to non-smokers; smokers were found to have significantly lower fundamental frequency values, and significantly higher jitter % and shimmer % values. Statistical significance was not found regarding fundamental frequency, jitter %, and shimmer % for age group comparisons. With regard to gender, statistical significance was found regarding fundamental frequency; females were found to have statistically higher fundamental frequencies as compared to males. However, the relationships between gender and jitter % and shimmer % lacked statistical significance. These results indicate that smoking negatively affects voice quality. This study also examined the ability of untrained listeners to identify smokers and non-smokers based on their voices. Results of this voice perception task suggest that listeners are not accurately able to identify smokers and non-smokers, as statistical significance was not reached. However, despite a lack of significance, trends in data suggest that listeners are able to utilize voice quality to identify smokers and non-smokers.

    Background Population-based data examining the relationship between social participation (SP) and instrumental activities of daily living (IADL) are scarce. This study examined the cross-sectional relationship between SP and IADL in community-dwelling elderly persons. Methods Self-administered questionnaires were mailed to 23 710 residents aged ≥65 years in Nara, Japan (response rate: 74.2%). Data from 14 956 respondents (6935 males and 8021 females) without dependency in basic activities of daily living (ADL) were analyzed. The number, type, and frequency of participation in social groups (SGs) were used to measure SP. SGs included volunteer groups, sports groups, hobby groups, senior citizens’ clubs, neighborhood community associations, and cultural groups. IADL was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Logistic regression models stratified by gender were used. Results After adjustment for putative confounding factors, including demographics, health status, life-style habits, ADL, depression, cognitive function, social networks, social support, and social roles, participation in various SGs among both genders was inversely associated with poor IADL, showing a significant dose-response relationship between an increasing number of SGs and a lower proportion of those with poor IADL (P for trend <0.001). A significant inverse association between frequent participation and poor IADL was observed for all types of SGs among females, whereas the association was limited to sports groups and senior citizens’ clubs among males. Conclusions Our results show that participation in a variety of SGs is associated with independent IADL among the community-dwelling elderly, regardless of gender. However, the beneficial effects of frequent participation on IADL may be stronger for females than for males. PMID:27180933

    At the 67th Gerontological Society of America Annual Meeting, a preconference workshop was convened to discuss the challenges of accurately assessing physical activity in older populations. The advent of wearable technology (eg, accelerometers) to monitor physical activity has created unprecedented opportunities to observe, quantify, and define physical activity in the real-world setting. These devices enable researchers to better understand the associations of physical activity with aging, and subsequent health outcomes. However, a consensus on proper methodological use of these devices in older populations has not been established. To date, much of the validation research regarding device type, placement, and data interpretation has been performed in younger, healthier populations, and translation of these methods to older populations remains problematic. A better understanding of these devices, their measurement properties, and the data generated is imperative to furthering our understanding of daily physical activity, its effects on the aging process, and vice versa. The purpose of this article is to provide an overview of the highlights of the preconference workshop, including properties of the different types of accelerometers, the methodological challenges of employing accelerometers in older study populations, a brief summary of ongoing aging-related research projects that utilize different types of accelerometers, and recommendations for future research directions.

    This paper presents the results of a descriptive survey on human grasps. Sixty-four videos were selected to represent tasks performed in the main areas of activities of daily living (ADL) (personal care, meal preparation, eating, housekeeping, etc.). All the participants were right-handed. Elementary grasps were identified for each hand, and the grasp type (from a 9-type classification), the hands involved, and the duration were registered for each case. The results show that the most commonly used grasps are: pinch, non-prehensile, cylindrical, lateral pinch and lumbrical. The presence of these grasps in the areas of ADL is, however, very different (e.g., pinch is widely used in food preparation and very little in driving). Some grasps were used more frequently with one hand or when both hands were used simultaneously (e.g., special pinch was hardly used by the left hand). Knowing the grasp types most frequently used in ADL is essential to be able to assess grasp rehabilitation processes or hand prostheses development.

    Mannoheptulose (MH), a sugar found in avocados that inhibits glycolysis in vitro, has been preliminarily investigated as a novel food ingredient for dogs. This study aimed to determine the effects of dietary MH, delivered as an extract of un-ripened avocado, on energy expenditure (EE) in healthy adult Labrador Retriever dogs (total of 12 dogs, 26.99 ± 0.634 kg, 4.9 ± 0.2 y). The study was a double-blind, cross-over with each dog receiving both dietary treatments, control (CON) and MH (400 mg/kg of diet; 6 mg/kg BW), in random order. Resting and post-prandial (10 h) EE and respiratory quotient (RQ) were determined by indirect calorimetry (d 42). The following day, body composition was assessed using dual X-ray absorptiometry. Continuous activity monitoring was conducted using an Atical® accelerometer (d 43-47). A vastus lateralis muscle biopsy was obtained prior to the morning meal (d 49) and 4 h after consumption of their meal (d 56) to determine the protein content and phosphorylation of 5' adenosine monophosphate-activated protein kinase (AMPK). Diet did not affect body weight, resting EE or skeletal muscle AMPK phosphorylation. Dogs fed MH had significantly lower post-prandial RQ (p = 0.02) and ratio of fat to lean body mass (p = 0.02). Physical activity during light time periods (but not dark) was lower in dogs fed MH (p < 0.05) during weekends, but not on weekdays. These results suggest that MH affects energy balance of adult dogs, but that these effects are not dose dependent and not due to physical activity. PMID:26656105

A vastus lateralis muscle biopsy was obtained prior to the morning meal (d 49) and 4 h after consumption of their meal (d 56) to determine the protein content and phosphorylation of 5' adenosine monophosphate-activated protein kinase (AMPK). Diet did not affect body weight, resting EE or skeletal muscle AMPK phosphorylation. Dogs fed MH had significantly lower post-prandial RQ (p = 0.02) and ratio of fat to lean body mass (p = 0.02). Physical activity during light time periods (but not dark) was lower in dogs fed MH (p < 0.05) during weekends, but not on weekdays. These results suggest that MH affects energy balance of adult dogs, but that these effects are not dose dependent and not due to physical activity.

    Mannoheptulose (MH), a sugar found in avocados that inhibits glycolysis in vitro, has been preliminarily investigated as a novel food ingredient for dogs. This study aimed to determine the effects of dietary MH, delivered as an extract of un-ripened avocado, on energy expenditure (EE) in healthy adult Labrador Retriever dogs (total of 12 dogs, 26.99 ± 0.634 kg, 4.9 ± 0.2 y). The study was a double-blind, cross-over with each dog receiving both dietary treatments, control (CON) and MH (400 mg/kg of diet; 6 mg/kg BW), in random order. Resting and post-prandial (10 h) EE and respiratory quotient (RQ) were determined by indirect calorimetry (d 42). The following day, body composition was assessed using dual X-ray absorptiometry. Continuous activity monitoring was conducted using an Atical® accelerometer (d 43–47).

    In this Phase I open-label study, the systemic absorption, clinical response, safety and tolerability of multiple-dose ozenoxacin 1% cream were evaluated in children (≥ 2 months of age) and adults with impetigo. A single (evening) dose of ozenoxacin 1% cream on day 1 was followed by twice-daily application for 4 days (every 12 h), and then a final single (morning) dose on day 6. A total of 46 patients were enrolled in the study. The majority of ozenoxacin plasma samples were below the limit of quantification (no systemic absorption). Approximately half (22/45) of the evaluable patients achieved clinical success (skin lesions were cured). No patients were withdrawn from the study because of a lack of healing or worsening of a lesion. Ozenoxacin was well tolerated in all patients. PMID:25209523

    Cognitive functioning influences activities of daily living (ADL). However, studies reporting the association between ADL and neuropsychological performance show inconsistent results regarding what specific cognitive domains are related to each specific functional domains. Additionally, whether depressive symptoms are associated with a worse functional performance in older adults is still under explored. We investigated if specific cognitive domains and depressive symptoms would affect different aspects of ADL. Participants were 274 older adults (96 normal aging participants, 85 patients with mild cognitive impairment, and 93 patients probable with mild Alzheimer’s disease dementia) with low formal education (∼4 years). Measures of ADL included three complexity levels: Self-care, Instrumental-Domestic, and Instrumental-Complex. The specific cognitive functions were evaluated through a factorial strategy resulting in four cognitive domains: Executive Functions, Language/Semantic Memory, Episodic Memory, and Visuospatial Abilities. The Geriatric Depression Scale measured depressive symptoms. Multiple linear regression analysis showed executive functions and episodic memory as significant predictors of Instrumental-Domestic ADL, and executive functions, episodic memory and language/semantic memory as predictors of Instrumental-Complex ADL (22 and 28% of explained variance, respectively). Ordinal regression analysis showed the influence of specific cognitive functions and depressive symptoms on each one of the instrumental ADL. We observed a heterogeneous pattern of association with explained variance ranging from 22 to 38%. Different instrumental ADL had specific cognitive predictors and depressive symptoms were predictive of ADL involving social contact. Our results suggest a specific pattern of influence depending on the specific instrumental daily living activity. PMID:26257644

    Social anhedonia (SA), the diminished pleasure from social relationships, is a prominent characteristic of the vulnerability and manifestation of schizophrenia disorder. However, SA can develop for multiple reasons and little is known about its neural basis; these 2 issues hinder the utility and sensitivity of SA as a marker of schizophrenia pathology. This study investigated whether lateral prefrontal cortex (LPFC) deficits in social reward processing are associated with both SA and other schizophrenia-spectrum symptoms. During functional MRI (fMRI), a community sample of healthy adults (N = 30) with high and low SA viewed positive, negative, and neutral facial expressions. Afterward, participants completed an online daily diary in which they rated schizophrenia-spectrum symptoms and occurrence of interpersonal conflict each day for 21 days. Compared with low SA, high SA participants had less ventral (V)LPFC activity to positive versus neutral expressions. In addition, participants with a combination of high SA and low VLPFC activity to positive versus neutral expressions had worse daily diary ratings of schizophrenia-spectrum symptoms, including worse cognition, paranoia, motivation/productivity, and vigor/positive affect (i.e., psychomotor activation). Finally, among high SA participants, VLPFC activity predicted the daily relationship between distress from interpersonal conflict and symptom-severity; specifically, high SA participants with low VLPFC activity had worse paranoia on days of high conflict distress. These findings indicate that VLPFC deficits in positive emotion are associated with both SA and other schizophrenia-spectrum symptoms and that understanding the interaction of SA, VLPFC function, and social stress could facilitate the use of SA in the prevention and treatment of schizophrenia.

    Background There is increasing interest in elucidating the association of different childhood adversities with psychosis-spectrum symptoms as well as the mechanistic processes involved. This study used experience sampling methodology to examine (i) associations of a range of childhood adversities with psychosis symptom domains in daily life; (ii) whether associations of abuse and neglect with symptoms are consistent across self-report and interview methods of trauma assessment; and (iii) the role of different adversities in moderating affective, psychotic-like, and paranoid reactivity to situational and social stressors. Method A total of 206 nonclinical young adults were administered self-report and interview measures to assess childhood abuse, neglect, bullying, losses, and general traumatic events. Participants received personal digital assistants that signaled them randomly eight times daily for one week to complete questionnaires about current experiences, including symptoms, affect, and stress. Results Self-reported and interview-based abuse and neglect were associated with psychotic-like and paranoid symptoms, whereas only self-reported neglect was associated with negative-like symptoms. Bullying was associated with psychotic-like symptoms. Losses and general traumatic events were not directly associated with any of the symptom domains. All the childhood adversities were associated with stress reactivity in daily life. Interpersonal adversities (abuse, neglect, bullying, and losses) moderated psychotic-like and/or paranoid reactivity to situational and social stressors, whereas general traumatic events moderated psychotic-like reactivity to situational stress. Also, different interpersonal adversities exacerbated psychotic-like and/or paranoid symptoms in response to distinct social stressors. Discussion The present study provides a unique examination of how childhood adversities impact the expression of spectrum symptoms in the real world and lends support

    The Food and Drug Administration mandated that by 1998, all enriched cereal grain products (ECGP) be fortified with folic acid in order to prevent the occurrence of neural tube defects. The Institute of Medicine established the tolerable upper intake level (UL) for folic acid (1000 µg/day for adults) in 1998. We characterized U.S. adults with usual daily folic acid intake exceeding the UL. Using NHANES 2003–2010 data, we estimated the percentage of 18,321 non-pregnant adults with usual daily folic acid intake exceeding the UL, and among them, we calculated the weighted percentage by sex, age, race/ethnicity, sources of folic acid intake, supplement use and median usual daily folic acid intakes. Overall, 2.7% (standard error 0.6%) of participants had usual daily intake exceeding the UL for folic acid; 62.2% were women; 86.3% were non-Hispanic whites; and 98.5% took supplements containing folic acid. When stratified by sex and age groups among those with usual daily folic acid intake exceeding the UL, 20.8% were women aged 19–39 years. Those with usual daily intake exceeding the folic acid UL were more likely to be female, non-Hispanic white, supplement users or to have at least one chronic medical condition compared to those not exceeding the folic acid UL. Among those with usual daily folic acid intake exceeding the UL who also took supplements, 86.6% took on average >400 µg of folic acid/day from supplements. Everyone with usual daily folic acid intake exceeding the UL consumed folic acid from multiple sources. No one in our study population had usual daily folic acid intake exceeding the UL through consumption of mandatorily-fortified enriched cereal grain products alone. Voluntary consumption of supplements containing folic acid is the main factor associated with usual daily intake exceeding the folic acid UL. PMID:27043623

  2. The Combined Effect of Neuropsychological and Neuropathological Deficits on Instrumental Activities of Daily Living in Older Adults: a Systematic Review.

    To date, studies have consistently demonstrated associations between either neuropsychological deficits or neuroanatomical changes and instrumental activities of daily living (IADL) in aging. Only a limited number of studies have evaluated morphological brain changes and neuropsychological test performance concurrently in relation to IADL in this population. As a result, it remains largely unknown whether these factors independently predict functional outcome. The current systematic review intended to address this lack of information by reviewing the literature on older adults, incorporating studies that examined e.g., normal aging, but also stroke or dementia patients. A comprehensive search of databases (Pubmed, Embase, Medline, Web of Science, PsycINFO) and reference lists was performed, focusing on papers in the English language that examined the combined effect of neuropsychological and neuroanatomical factors on IADL in samples of adults with an average age above 50. In total, 58 potential articles were identified; 20 were included in the review. The results show that especially neuropsychological variables (primarily memory and executive functions) independently predict IADL. Although some unique predictive value of brain morphological changes, such as hippocampal atrophy, was found, support for the importance of white matter changes was limited. However, the results of the studies reviewed are diverse, and appear to be at least partially determined by the variables included. For example, studies were less likely to find an independent effect of cognition if they solely employed a cognitive screening instrument. This indicates that a structured examination of neuroanatomical and neuropsychological correlates of IADL in different patient populations is warranted.

    Rotator cuff tears (RCT) in older individuals may compound age-associated physiological changes and impact their ability to perform daily functional tasks. Our objective was to quantify thoracohumeral kinematics for functional tasks in 18 older adults (mean age=63.3±2.2), and compare findings from nine with a RCT to nine matched controls. Motion capture was used to record kinematics for 7 tasks (axilla wash, forward reach, functional pull, hair comb, perineal care, upward reach to 90°, upward reach to 105°) spanning the upper limb workspace. Maximum and minimum joint angles and motion excursion for the three thoracohumeral degrees of freedom (elevation plane, elevation, axial rotation) were identified for each task and compared between groups. The RCT group used greater minimum elevation angles for axilla wash and functional pull (p≤0.0124) and a smaller motion excursion for functional pull (p=0.0032) compared to the control group. The RCT group also used a more internally rotated maximum axial rotation angle than controls for functional reach, functional pull, hair comb, and upward reach to 105° (p≤0.0494). The most differences between groups were observed for axial rotation, with the RCT group using greater internal rotation to complete functional tasks, and significant differences between groups were identified for all three thoracohumeral degrees of freedom for functional pull. We conclude that older adults with RCT used more internal rotation to perform functional tasks than controls. The kinematic differences identified in this study may have consequences for progression of shoulder damage and further functional impairment in older adults with RCT. PMID:26879327

    Cigarette smoking is an economically and epidemiologically expensive public health concern. Most adult smokers become addicted during adolescence, rendering it a crucial period for prevention and intervention. Although litigation claims have delayed implementation, graphic warning labels proposed by the U.S. Food and Drug Administration (FDA) may be a promising way to achieve this goal. We aimed to determine the efficacy of the labels in reducing in-scanner craving and to characterize the neurobiological responses in adolescent and adult smokers and non-smokers. While undergoing functional magnetic resonance imaging, thirty-nine 13- to 18-year-old adolescent and forty-one 25- to 30-year-old adult smokers and non-smokers rated their desire to smoke when presented with emotionally graphic warning labels and comparison non-graphic labels. Compared with adult smokers, adolescent smokers exhibited greater craving reduction in response to the warning labels. Although smokers evinced overall blunted recruitment of insula and dorsolateral prefrontal cortex (DLPFC) relative to non-smokers, an effect that was stronger in adolescent smokers, parametrically increasing activation of these regions was associated with greater craving reduction. Functional connectivity analyses suggest that greater DLPFC regulation of limbic regions predicted cigarette craving. These data underscore a prominent role of frontoinsular circuitry in predicting the efficacy of FDA graphic warning labels in craving reduction in adult and adolescent smokers. PMID:25887154

    A high incidence of limitations in daily functioning is seen in older adults with intellectual disabilities (ID), along with poor physical fitness levels. The aim of this study was to assess the predictive value of physical fitness for daily functioning after 3 years, in 602 older adults with borderline to profound ID (≥ 50 years). At baseline, physical fitness levels and daily functioning (operationalized as basic activities of daily living [ADL] and mobility) were assessed. After 3 years, the measurements of daily functioning were repeated. At follow-up, 12.6% of the participants were completely independent in ADL and 48.5% had no mobility limitations. More than half of the participants (54.8%) declined in their ability to perform ADL and 37.5% declined in their mobility. Manual dexterity, visual reaction time, balance, comfortable and fast gait speed, muscular endurance, and cardiorespiratory fitness were significant predictors for a decline in ADL. For a decline in mobility, manual dexterity, balance, comfortable and fast walking speed, grip strength, muscular endurance, and cardiorespiratory fitness were all significant predictors. This proves the predictive validity of these physical fitness tests for daily functioning and stresses the importance of using physical fitness tests and implementing physical fitness enhancing programs in the care for older adults with ID.

    This study aims to answer the research question of "Are early onset aging conditions correlated to daily activity functions in youth and adults with Down syndrome (DS)?" A cross-sectional survey was employed to recruit 216 individuals with DS over 15 years of age in the analyses. A structured questionnaire included demographic data, brief self-reported aging conditions, Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) and activity of daily living (ADL) scales were completed by the primary caregivers who were well-suited for providing information on the functioning conditions of the DS individuals. Results showed that the most five frequent aging conditions (sometimes, usually and always) included frailty (20.2%), vision problem (15.8%), loss of language ability (15.3%), sleep problem (14.9%) and memory impairment (14.5%). Other onset aging conditions included more chronic diseases (13.9%), hearing loss (13%), chewing ability and tooth loss (12.5%), incontinence (11.1%), depressive syndrome (7.7%), falls and gait disorder (7.2%), loss of taste and smell (7.2%). The data also showed scores of DSQIID, onset aging conditions and ADL has significant relationships each other in Pearson's correlation tests. Finally, multiple linear regression analyses indicated onset aging conditions (β=-0.735, p<0.001) can significantly predicted the variation in ADL scores after adjusting other factors (R(2)=0.381). This study suggests that the authority should initiate early intervention programs aim to improve healthy aging and ADL functions for people with DS. PMID:25462513

    Background Total sedentary time varies across population groups with important health consequences. Patterns of sedentary time accumulation may vary and have differential health risks. The purpose of this study is to describe sedentary patterns of older adults living in retirement communities and illustrate gender and age differences in those patterns. Methods Baseline accelerometer data from 307 men and women (mean age = 84±6 years) who wore ActiGraph GT3X+ accelerometers for ≥ 4 days as part of a physical activity intervention were classified into bouts of sedentary time (<100 counts per minute). Linear mixed models were used to account for intra-person and site-level clustering. Daily and hourly summaries were examined in mutually non-exclusive bouts of sedentary time that were 1+, 5+, 10+, 20+, 30+, 40+, 50+, 60+, 90+ and 120+ minutes in duration. Variations by time of day, age and gender were explored. Results Men accumulated more sedentary time than women in 1+, 5+, 10+, 20+, 30+, 40+, 50+ and 60+ minute bouts; the largest gender-differences were observed in 10+ and 20+ minute bouts. Age was positively associated with sedentary time, but only in bouts of 10+, 20+, 30+, and 40+ minutes. Women had more daily 1+ minute sedentary bouts than men (71.8 vs. 65.2), indicating they break up sedentary time more often. For men and women, a greater proportion of time was spent being sedentary during later hours of the day than earlier. Gender differences in intra-day sedentary time were observed during morning hours with women accumulating less sedentary time overall and having more 1+ minute bouts. Conclusions Patterns identified using bouts of sedentary time revealed gender and age differences in the way in which sedentary time was accumulated by older adults in retirement communities. Awareness of these patterns can help interventionists better target sedentary time and may aid in the identification of health risks associated with sedentary behavior. Future studies

    Background Plain packaging (PP) with larger graphic health warnings (GHWs) was implemented in Australia in late 2012. This study examined effects of these packaging changes on short-term changes in quitting-related cognitions and behaviours. Methods We used a series of cohorts of Australian adult cigarette smokers originally sourced from a nationally representative cross-sectional tracking survey, followed up approximately 1 month after their baseline interview (n(weighted)=5441). Logistic regression analyses compared changes in seven quitting-related outcomes over this 1-month follow-up period for the cohorts surveyed before PP, over the period of transition to PP, and during the first year of PP, adjusting for baseline levels of the outcome and covariates. Results Compared to the referent group of smokers who completed their follow-up survey pre-PP, those who were followed-up in the early transition period showed significantly greater increases in rates of stopping themselves from smoking (OR=1.51, 95% CI (1.08 to 2.10)) and higher quit attempt rates (OR=1.43, 95% CI (1.00 to 2.03)), those followed-up in the late transition period showed greater increases in intentions to quit (OR=1.42, 95% CI (1.06 to 1.92)) and pack concealment (OR=1.55, 95% CI (1.05 to 2.31)), and those followed-up in the first year of PP showed higher levels of pack concealment (OR=1.65, 95% CI (1.01 to 2.72)), more premature stubbing out of cigarettes (OR=1.55, 95% CI (1.01 to 2.36)), and higher quit attempt rates (OR=1.52, 95% CI (1.01 to 2.30)). Conclusions These findings provide some of the strongest evidence to date that implementation of PP with larger GHWs was associated with increased rates of quitting cognitions, microindicators of concern and quit attempts among adult cigarette smokers.

    Caffeine-containing energy drinks have emerged as a public health concern due to their association with caffeine toxicity and alcohol use. Despite the fact that previous research has linked caffeine use in the form of coffee drinking to smoking, there is little research examining the association between energy drinks and smoking. The present study examines demographic and behavioral factors associated with energy drink use among a sample of rural Ohio Appalachian smokers. It was hypothesized that male gender, young age (21-30 years.) and alcohol use would be associated with energy drink use. A sample of adult smokers (n = 298) from Ohio Appalachian counties were interviewed regarding demographic and behavioral factors. Logistic regression analysis was used to assess the association between these factors and energy drink use. Seventy percent of Ohio Appalachian smokers studied had ever used an energy drink and 40 % had used an energy drink in the past month. Young age, male gender, and single marital status were associated with higher odds of ever having used an energy drink. Young age, and binge drinking were associated with higher odds of past 30-day use while abstinence from drinking was associated with lower odds of past 30-day use. Ohio Appalachian adult smokers had higher rates of energy drink use compared to previous estimates of ever or past month use found in other studies. The combined use of caffeine, nicotine, and alcohol warrants attention due to potential for health risk.

    Studies investigating possible associations between iron status and mood or depressive symptoms have reported inconsistent results. However, they have neither used body iron to measure iron status nor measured mood using daily measures. We investigated whether body iron was associated with depressive symptoms, daily mood, daily tiredness, difficulty concentrating, and stress in young adult women and men. Young adult (17-25 years) women (n = 562) and men (n = 323) completed the Center for Epidemiologic Studies Depression Scale, then reported negative and positive mood, and other states daily for 13 days. Non-fasting venous blood was collected to determine hemoglobin, serum ferritin and soluble transferrin receptor (to calculate body iron), C-reactive protein, and alpha-1-acid glycoprotein concentration. Regression models tested linear associations between body iron and the outcome variables, controlling for possible confounders. No associations were found between body iron and the outcome variables in women. However, higher body iron was associated with more depressive symptoms in men (3.4% more per body iron mg/kg; 95% confidence intervals (CI): 0.8%, 5.9%). In young adult women, body iron is unlikely to be associated with significant deficits in mood or depressive symptoms. However, higher body iron may be associated with more depressive symptoms in young adult men. PMID:26213963

    Purpose: Back pain is the leading cause of global years lived with disability. This cross-sectional study assessed if a greater exposure to smoking cigarettes was associated with a greater prevalence of back pain. Methods: This study examined data from 34,525 United States adults from the 2012 National Health Interview Survey. Analyses assessed the difference in back pain prevalence among current smokers, former smokers, and never smokers and the number of cigarettes smoked between current smokers with and without back pain. Results: Back pain prevalence was 28%. There was a significant association between back pain and smoking, X2 (2, 599, n = 34, 241) = 546.3, p < .001. Back pain increased with increased smoking exposure; back pain was present in 23.5% of never-smokers, 33.1% of former smokers, and 36.9% of current smokers. The number of cigarettes smoked per day for current daily smokers was higher for those with back pain (Md = 13) than those without back pain (Md = 10), U = 2701065, z = -3.70, p < .001, r = .05. Conclusions: Our findings suggest that there may be a biological gradient associated with exposure to smoking cigarettes and back pain in adult Americans. PMID:27790393

  17. Effect of smoking characteristics on cognitive dissonance in current and former smokers.

    The effect of smoking characteristics on the development of cognitive dissonance in current and former smokers is examined. Smoking characteristics (number of cigarettes per day, number of years smoked, and years since quitting) and health beliefs were obtained from over 9,000 respondents to the 1986 Adult Use of Tobacco Survey. Overall, current smokers exhibited more cognitive dissonance involving smoking-related beliefs than did former smokers. Logistic regression analysis indicated that heavier current smokers (those smoking > or = 20 cigarettes per day) were more likely to exhibit cognitive dissonance over smoking-related health beliefs than were lighter smokers. In contrast, number of cigarettes consumed per day had only minor effects on former smokers' beliefs; former smokers who had smoked for more years (> or = 17), or who had quite recently (within the last 8 years), were more likely to showed greater dissonance than former smokers without these characteristics. The factors underlying these results and their implications for smoking cessation programs are discussed.

    This cross-sectional study examined the differences in barriers to cessation and reasons for quitting smoking among dual smokers of cigarettes and waterpipe tobacco, exclusive cigarette smokers and exclusive waterpipe smokers. Participants were Arab American adults residing in Richmond, Virginia, who were recruited from Middle Eastern grocery stores, restaurants/lounges and faith and charity organizations. The study yielded several key findings: (1) Exclusive cigarette and waterpipe smokers had similar mean barriers to quitting and were more concerned about their health than dual smokers. (F(2, 150) = 5.594, p = 0.0045). This implies that barriers to smoking and health concerns could be a function of the individual who smokes rather than the modality of smoking itself. (2) Exclusive cigarette or waterpipe smokers and dual smokers may have different reasons for quitting, since they have different reasons for smoking. The proportion of smokers who endorsed smoking as a messy habit as the reason among exclusive cigarette smokers was 0.37, whereas the proportion among exclusive waterpipe smokers was 0.04 and among dual smokers 0.39. The difference in proportions is significant, χ2 (df = 2, N = 154) = 13.17, p = 0.0014. In summary, this study supports the need to further investigate dual cigarette and waterpipe smokers, as the study results indicate greater barriers to smoking cessation in this group. Recognition and understanding of these barriers among dual tobacco users would be important for any future tobacco intervention among waterpipe smokers. PMID:25226410

  19. [Salivary, urinary and plasma thiocyanate in smokers and non-smokers].

    1983-03-01

    Thiocyanate is a major metabolic product of hydrocyanic acid. Its concentration in the serum, urine and saliva of individuals with little exposure to hydrocyanic acid (i.e. non smokers) is very low. But about three fold higher concentrations of thiocyanate are found in the sera, urine and saliva of smokers as compared to non smokers, because of cyanide provided by cigarette smoke. The concentrations of thiocyanate in the three biological fluids studied were different and it appeared to be no correlation in the distribution of thiocyanate concentrations in these fluids when individual subjects were compared. Urinary and salivary concentration power showed decreased kidney excretion of thiocyanate in smokers. The appearance or the disappearance of thiocyanates in the saliva and the urine takes place slowly. The salivary or urinary levels of thiocyanates are therefore good indicators of chronic intoxication from tobacco because it is not very sensitive to daily variations in tobacco smoking; it reflects the slow transformation of cyanide as well as the final elimination of this ion from urine which is slowed down in smokers.

    Objectives To explore associations between subjective social status (SSS) and smoking level among 2274 adult current smokers. Methods Associations were investigated using a covariate-adjusted proportional odds cumulative logit model. Moderation (via race/ethnicity or sex) and mediation (via depressive symptoms, social/emotional support, or life satisfaction) were explored in additional models. Results Higher SSS was associated with greater likelihood of nondaily versus light daily or moderate/ heavy daily smoking (p = .017). Life satisfaction partially mediated the association of SSS and smoking level (p = .003). Conclusions Higher SSS was associated with greater likelihood of nondaily relative to light daily or moderate to heavy smoking, potentially via greater life satisfaction. Additional studies are needed to confirm these findings. PMID:24629553

    The ability to recognize and label emotional experiences has been associated with well-being and adaptive functioning. This skill is particularly important in social situations, as emotions provide information about the state of relationships and help guide interpersonal decisions, such as whether to disclose personal information. Given the interpersonal difficulties linked to social anxiety disorder (SAD), deficient negative emotion differentiation may contribute to impairment in this population. We hypothesized that people with SAD would exhibit less negative emotion differentiation in daily life, and these differences would translate to impairment in social functioning. We recruited 43 people diagnosed with generalized SAD and 43 healthy adults to describe the emotions they experienced over 14 days. Participants received palmtop computers for responding to random prompts and describing naturalistic social interactions; to complete end-of-day diary entries, they used a secure online website. We calculated intraclass correlation coefficients to capture the degree of differentiation of negative and positive emotions for each context (random moments, face-to-face social interactions, and end-of-day reflections). Compared to healthy controls, the SAD group exhibited less negative (but not positive) emotion differentiation during random prompts, social interactions, and (at trend level) end-of-day assessments. These differences could not be explained by emotion intensity or variability over the 14 days, or to comorbid depression or anxiety disorders. Our findings suggest that people with generalized SAD have deficits in clarifying specific negative emotions felt at a given point of time. These deficits may contribute to difficulties with effective emotion regulation and healthy social relationship functioning.

    Background At present smoking is considered a great health-related problem. Smoking cigarettes and use of tobacco are on the rise in the Middle East countries; therefore, the number of people exposed to passive cigarette smoke is increasing, too. The aim of the present study was to determine and compare salivary cotinine levels in hookah smokers, individuals exposed to passive cigarette smoke and non-smoker (passive smokers). Methods In the present cross-sectional study, unstimulated salivary samples were collected from 150 subjects, including 50 hookah smokers, 50 passive smokers, and 50 non-smokers. Bioassay Technology Laboratory cotinine kit was used to determine salivary levels of cotinine using the enzyme-linked immunosorbent assay (ELISA) technique at a sensitivity rate of 0.019 pg/ml. Data were analyzed with SPSS software using t-test and Pearson’s correlation coefficient. Findings The highest salivary cotinine levels were recorded in hookah users (20.24 ± 5.62 ng/ml), followed by passive smokers (16.09 ± 3.51 ng/ml), in descending order. No detectable cotinine levels were observed in non-smokers. Pearson’s correlation coefficient showed a strong and positive correlation between use of hookah and salivary cotinine levels (r = 0.932, P = 0.001). Conclusion Based on the results of the present study, salivary cotinine levels were higher in hookah smokers compared with passive smokers and non-smokers, in descending order. PMID:26885355

    Context In India, 14% of the population use smoked tobacco products. Increasing prices of these products is one of the measures to curb their consumption. Aims This study analyzes ‘unit price’ and ‘daily consumption’ of cigarettes and bidis and investigates their relation with each other. Settings and Design A cross sectional survey was conducted in four states of India (Bihar, West Bengal, Madhya Pradesh and Maharashtra) as a part of the International Tobacco Control Policy Evaluation Project (the TCP India Project) during 2010-11. Methods Information was collected from adult (aged ≥15) daily exclusive smokers of cigarette /bidi regarding a) last purchase (purchase in pack/loose, brand and price) and b) daily consumption. Average unit price and daily consumption was calculated for different brands and states. Regression model was used to assess the impact of price on daily consumption. Results Bidis were much less expensive (Rs. 0.39) than cigarettes (Rs. 3.1). The daily consumption was higher (14) among bidi smokers than cigarette smokers (8). The prices and daily consumption of bidis (Rs. 0.33 to 0.43; 12 to 15) and cigarettes (Rs. 2.9 to 3.6; 5 to 9) varied across the four states. The unit prices of bidis and cigarettes did not influence their daily consumption. Smokers purchasing bidis in packs paid substantially less per unit and purchase of bidis and cigarettes in packs influenced their consumption positively. Conclusions Cigarettes although more expensive than bidis, seem very cheap if compared internationally. Hence, prices of both cigarettes and bidis do not influence their consumption. PMID:25526256

    Objective To assess the impact of a 2007 cigarette tax increase from 110% to 140% of the price to the retailer on cigarette price and consumption among Mexican smokers, including efforts to offset price increases. Methods Data were analysed from the 2006 and 2007 administrations of the International Tobacco Control (ITC) Policy Evaluation Survey in Mexico, which is a population-based cohort of adult smokers. Self-reported price of last cigarette purchase, place of last purchase, preferred brand, daily consumption and quit behaviour were assessed at baseline and follow-up. Results Self-reported cigarette prices increased by 12.7% after the tax increase, with prices for international brands increasing more than for national brands (13.5% vs 8.7%, respectively). Although the tax increases were not fully passed onto consumers particularly on national brands, no evidence was found for smokers changing behaviour to offset price increases. Consistent declines in consumption across groups defined by sociodemographic and smoking-related psychosocial variables suggest a relatively uniform impact of the tax increase across subpopulations. However, decreased consumption appeared limited to people who smoked relatively more cigarettes a day (>5 cigarettes/day). Average daily consumption among lighter smokers did not significantly decline. A total of 13% (n=98) of the sample reported being quit for a month or more at follow-up. In multivariate models, lighter smokers were more likely than heavier smokers to be quit. Conclusions Results suggest that the 2007 tax increase was passed on to consumers, whose consumption generally declined. Since no other tobacco control policies or programmes were implemented during the period analysed, the tax increase appears likely to have decreased consumption. PMID:20870740

  8. Daily rhythms of core temperature and locomotor activity indicate different adaptive strategies to cold exposure in adult and aged mouse lemurs acclimated to a summer-like photoperiod.

    Daily variations in core temperature (Tc) within the normothermic range imply thermoregulatory processes that are essential for optimal function and survival. Higher susceptibility towards cold exposure in older animals suggests that these processes are disturbed with age. In the mouse lemur, a long-day breeder, we tested whether aging affected circadian rhythmicity of Tc, locomotor activity (LA), and energy balance under long-day conditions when exposed to cold. Adult (N = 7) and aged (N = 5) mouse lemurs acclimated to LD14/10 were exposed to 10-day periods at 25 and 12 degrees C. Tc and LA rhythms were recorded by telemetry, and caloric intake (CI), body mass changes, and plasma IGF-1 were measured. During exposure to 25 degrees C, both adult and aged mouse lemurs exhibited strong daily variations in Tc. Aged animals exhibited lower levels of nocturnal LA and nocturnal and diurnal Tc levels in comparison to adults. Body mass and IGF-1 levels remained unchanged with aging. Under cold exposure, torpor bout occurrence was never observed whatever the age category. Adult and aged mouse lemurs maintained their Tc in the normothermic range and a positive energy balance. All animals exhibited increase in CI and decrease in IGF-1 in response to cold. The decrease in IGF-1 was delayed in aged mouse lemurs compared to adults. Moreover, both adult and aged animals responded to cold exposure by increasing their diurnal LA compared to those under Ta = 25 degrees C. However, aged animals exhibited a strong decrease in nocturnal LA and Tc, whereas cold effects were only slight in adults. The temporal organization and amplitude of the daily phase of low Tc were particularly well preserved under cold exposure in both age groups. Sexually active mouse lemurs exposed to cold thus seemed to prevent torpor exhibition and temporal disorganization of daily rhythms of Tc, even during aging. However, although energy balance was not impaired with age in mouse lemurs after cold exposure

    In addition to morphological and physiological traits of short-day acclimatisation, Djungarian hamsters (Phodopus sungorus) from Central Asia exhibit spontaneous daily torpor to decrease energy demands during winter. Environmental factors such as food scarcity and low temperatures have been shown to facilitate the use of this temporal reduction in metabolism and body temperature. We investigated the effect of a daily cycle in ambient temperature on short-day acclimation and torpor expression in juvenile and adult Djungarian hamsters. The animals were exposed to a cold dark phase (6°C) and a warmer light phase (18°C) and were compared with control hamsters kept at a constant ambient temperature of 18°C. Under constant conditions, torpor expression did not differ between adult and juvenile hamsters. Although the daily temperature cycle evoked an increased metabolic rate in adult and juvenile hamsters during the dark phase and strengthened the synchronization between torpor entrance and the beginning of the light phase, it did not induce the expected torpor facilitation. In adult hamsters, torpor expression profiles did not differ from those under constant conditions at all. In contrast, juvenile hamsters showed a delayed onset of torpor season, a decreased torpor frequency, depth and duration, as well as an increased number of early torpor terminations coinciding with the rise in ambient temperature after the beginning of the light phase. While the temperature challenge appeared to be of minor importance for energy balance and torpor expression in adult hamsters, it profoundly influenced the overall energy saving strategy of juvenile hamsters, promoting torpor-alleviating active foragers over torpor-prone energy-savers. In addition, our data suggest a more efficient acclimation in juvenile hamsters under additional energy challenges, which reduces the need for torpor expression.

    Loneliness is common in persons living with HIV (PLWH). Lonely people smoke at higher rates than the general population, and loneliness is a likely contributor to the ongoing smoking epidemic among PLWH. We explored factors associated with loneliness in a cohort of 272 PLWH smokers enrolled in two separate tobacco treatment trials. Loneliness was independently associated with lack of a spouse or partner, lower educational attainment, “other or unknown” HIV exposure category, depression, anxiety, recent alcohol consumption, and higher daily cigarette consumption. Referral to group therapy reduced loneliness whereas referral to an individual web-based tobacco treatment did not. PMID:25298196

    Smoking has been identified as the second greatest risk factor for global death and disability and has impacts on the oral cavity from aesthetic changes to fatal diseases such as oral cancer. The paper presents a secondary analysis of the National Adult Dental Health Survey (2009). The analysis used descriptive statistics, bivariate analyses and logistic regression models to report the self-reported oral health status and dental attendance of smokers and non-smokers in England. Of the 9,657 participants, 21% reported they were currently smoking. When compared with smokers; non-smokers were more likely to report ‘good oral health’ (75% versus 57% respectively, p<0.05). Smokers were twice as likely to attend the dentist symptomatically (OR = 2.27, CI = 2.02–2.55) compared with non-smoker regardless the deprivation status. Smokers were more likely to attend symptomatically in the most deprived quintiles (OR = 1.99, CI = 1.57–2.52) and perceive they had poorer oral health (OR = 1.77, CI = 1.42–2.20). The present research is consistent with earlier sub-national research and should be considered when planning early diagnosis and management strategies for smoking-related conditions, considering the potential impact dental teams might have on smoking rates.

We examined whether this relationship remains evident within the South Korean population. Specifically, we investigated the effect of secondhand smoking on depressive symptoms and suicidal ideation. Methods We analyzed data from 6,043 non-smoking adults who participated in the 2010–2012 Korea National Health and Nutrition Examination Survey. We compared the presence of depressive symptoms and suicidal ideation in 3,006 participants who were exposed to secondhand smoking in the office or at home with 3,037 non-exposed participants. Results In unadjusted logistic regression analysis, secondhand smoking exposure group had more suicidal ideations than no secondhand smoking exposure (16.1% vs. 12.2%; odds ratio [OR], 1.50; 95% confidence interval [CI], 1.241–1.804), but risk of depressive symptoms was not significantly different between two groups (15.2% vs. 12.2%; OR, 1.21; 95% CI, 0.997–1.460). In multivariate logistic regression analysis, Among those exposed to secondhand smoking, the OR for depressive symptoms was 1.02 (95% CI, 0.866–1.299) and 1.43 (95% CI, 1.139–1.802) for suicidal ideation. Overall, secondhand smoking at home was significantly related to depressive symptoms and suicidal ideation. Among females, secondhand smoking exposure at home only (not in the office) was related to depressive symptoms and suicidal ideation. Conclusion Exposure to secondhand smoking, especially at home, may be associated with an increase in especially in female depressive symptoms and suicidal ideation among adults in South Korea.

    Social insects control brood development by using different thermoregulatory strategies. Camponotus mus ants expose their brood to daily temperature fluctuations by translocating them inside the nest following a circadian rhythm of thermal preferences. At the middle of the photophase brood is moved to locations at 30.8°C; 8 h later, during the night, the brood is transferred back to locations at 27.5°C. We investigated whether daily thermal fluctuations experienced by developing pupae affect the neuroarchitecture in the adult brain, in particular in sensory input regions of the mushroom bodies (MB calyces). The complexity of synaptic microcircuits was estimated by quantifying MB-calyx volumes together with densities of presynaptic boutons of microglomeruli (MG) in the olfactory lip and visual collar regions. We compared young adult workers that were reared either under controlled daily thermal fluctuations of different amplitudes, or at different constant temperatures. Thermal regimes significantly affected the large (non-dense) olfactory lip region of the adult MB calyx, while changes in the dense lip and the visual collar were less evident. Thermal fluctuations mimicking the amplitudes of natural temperature fluctuations via circadian rhythmic translocation of pupae by nurses (amplitude 3.3°C) lead to higher numbers of MG in the MB calyces compared to those in pupae reared at smaller or larger thermal amplitudes (0.0, 1.5, 9.6°C), or at constant temperatures (25.4, 35.0°C). We conclude that rhythmic control of brood temperature by nursing ants optimizes brain development by increasing MG densities and numbers in specific brain areas. Resulting differences in synaptic microcircuits are expected to affect sensory processing and learning abilities in adult ants, and may also promote interindividual behavioral variability within colonies.

    Objectives In 2002, Taiwan launched a program to encourage doctors to provide brief cessation counselling to their patients during routine outpatient visits. This study is to compare and analyse the annual prevalence rate of receiving advice to quit smoking from health professionals before (2004) and after (2005, 2006) the increase in funding and the withdrawal of additional funding (2007). Methods We analysed pooled data from 2004 to 2007 Taiwan Adult Tobacco Survey, an annual random digit dialling telephone survey, to estimate the prevalence of receiving quit advice among ever smokers across these years. Smoking characteristics and the socioeconomic factors of smokers associated with receipt of advice to quit smoking were also examined. Results The prevalence rate of receiving quit advice increased from 21.1% in 2004 to 28.2% in 2006, and then decreased slightly to 27.6% in 2007 after the funds were cut. Multivariate analyses results indicated that increasing financing for smoking cessation services in 2005, being male, older, a daily cigarette user, having previously attempted to quit, perceiving oneself as having poor health and being aware of the benefits of smoking cessation services were significantly positively associated with receiving quit advice from health professionals. In contrast, smokers who were younger, female and occasional cigarette users were less likely to receive quit advice. Also, smokers with socioeconomic disadvantages were not less likely to receive quit advice. Conclusions During the period of increased funding for smoking cessation services, the rates of receiving quit advice increased among all smokers and across different socioeconomic groups.

    To investigate the role of the tobacco industry in marketing to and sustaining tobacco addiction among older smokers and aging baby boomers, We performed archival searches of electronic archives of internal tobacco company documents using a snowball sampling approach. Analysis was done using iterative and comparative review of documents, classification by themes, and a hermeneutic interpretive approach to develop a case study. Based on extensive marketing research, tobacco companies aggressively targeted older smokers and sought to prevent them from quitting. Innovative marketing approaches were used. "Low tar" cigarettes were developed in response to the health concerns of older smokers, despite industry knowledge that such products had no health advantage and did not help smokers quit. Tobacco industry activities influence the context of cessation for older smokers in several ways. Through marketing "low tar" or "light" cigarettes to older smokers "at risk" of quitting, the industry contributes to the illusion that such cigarettes are safer, although "light" cigarettes may make it harder for addicted smokers to quit. Through targeted mailings of coupons and incentives, the industry discourages older smokers from quitting. Through rhetoric aimed at convincing addicted smokers that they alone are responsible for their smoking, the industry contributes to self-blame, a documented barrier to cessation. Educating practitioners, older smokers, and families about the tobacco industry's influence may decrease the tendency to "blame the victim," thereby enhancing the likelihood of older adults receiving tobacco addiction treatment. Comprehensive tobacco control measures must include a focus on older smokers.

  1. Consumption of single cigarettes and quitting behavior: A longitudinal analysis of Mexican smokers

    PubMed Central

    2011-01-01

    Background Previous cross-sectional research has suggested single cigarettes could either promote or inhibit consumption. The present study aimed to assess the effects of single cigarette availability and consumption on downstream quit behavior. Methods We analyzed population-based, longitudinal data from adult smokers who participated in the 2008 and 2010 administrations of the International Tobacco Control Policy Evaluation Survey in Mexico. Results At baseline, 30% of smokers saw single cigarettes for sale on a daily basis, 17% bought singles at their last purchase, and 7% bought singles daily. Smokers who most frequently purchased singles, both in general and specifically to control their consumption, were no more likely to attempt to quit over the 14 month follow-up period than those who did not purchase singles. Frequency of buying singles to reduce consumption had a non-monotonic association with being quit at followup. The odds of being quit was only statistically significant when comparing those who had not bought singles to reduce consumption with those who had done so on a more irregular basis (AOR = 2.30; 95% CI 1.19, 4.45), whereas those who did so more regularly were no more likely to be quit at followup. Frequency of self-reported urges to smoke upon seeing singles for sale was unassociated with either quit attempts or being quit at followup. Conclusions These results suggest that the relationship between singles consumption and quit behavior is complex, with no clear evidence that singles either promote or inhibit downstream quit behavior.

  2. Lung Cancer in Never Smokers.

    Lung cancer is predominantly associated with cigarette smoking; however, a substantial minority of patients with the disease have never smoked. In the US it is estimated there are 17,000-26,000 annual deaths from lung cancer in never smokers, which as a separate entity would be the seventh leading cause of cancer mortality. Controversy surrounds the question of whether or not the incidence of lung cancer in never-smokers is increasing, with more data to support this observation in Asia. There are several factors associated with an increased risk of developing lung cancer in never smokers including second hand smoke, indoor air pollution, occupational exposures, and genetic susceptibility among others. Adenocarcinoma is the most common histology of lung cancer in never smokers and in comparison to lung cancer in smokers appears less complex with a higher likelihood to have targetable driver mutations.

    Background: As most smokers initiate smoking during adolescence, assessment of smoking motives that underlie trajectories of dependence is critical for both prevention and cessation efforts. In the current study, we expected participants with higher nicotine dependence would smoke (a) less for positive reinforcement (PR) and (b) more for negative reinforcement (NR) motives. We secondarily assessed the relative contribution of PR to NR motives across levels of dependence. Methods: Data were drawn from a study on cue-elicited craving among occasional versus daily adolescent smokers aged 16–20 years (N = 111). Smoking motives were assessed in relation to 3 commonly used measures of nicotine dependence: (a) Fagerström Test for Nicotine Dependence (FTND), (b) Autonomy over Smoking Scale (AUTOS), and (c) Nicotine Dependence Syndrome Scale (NDSS). Results: Compared to occasional smokers, daily smokers had significantly higher scores on each dependence measure and endorsed more prominent NR smoking motives. Each measure of nicotine dependence was strongly associated with NR motives for smoking, although measures differed in their association with PR motives. As expected, the FTND, AUTOS, and NDSS each significantly predicted smoking motive difference score (PR − NR), such that higher dependence was associated with more prominent NR motives for smoking. Conclusions: Results are consistent with our understanding of dependence and provide further support for 3 common measures of nicotine dependence among early stage smokers. PMID:24924155

    Cigarette smoking during young adult may result in serious health issues in later life. Hence, it is extremely necessary to study the smoking neurophysiological mechanisms in this critical transitional period. However, few studies revealed the electrophysiological mechanisms of cognitive processing biases in young adult smokers. In present study, nineteen young smokers with 12h abstinent and 19 matched nonsmokers were recruited. By employing event-related potentials (ERP) measurements during a smoking cue induced craving task, electrophysiological brain responses were compared between the young adult smokers and nonsmokers. The Slow Positive Wave (SPW) amplitude of smoking-related cues was enhanced in young adult smokers compared with nonsmokers. In addition, increased P300/SPW component of smoking-related cues relative to neutral cues were found in young adult smokers. Meanwhile, a positive correlation between Cigarette Per Day (CPD) and the amplitude of ERPs wave (P300/SPW) at anterior (Fz), central (Cz) were observed in young adult smokers. Our findings provided direct electrophysiological evidence for the cognitive processing bias of smoking cue and may shed new insights into the smoking behavior in young adult smokers.

    The relationship of coronary artery disease (CAD) in ex-smokers has not been elucidated, although smoking is considered to be one of the major risk factors of CAD. We investigate subclinical coronary atherosclerosis (SCA) in asymptomatic subjects with coronary computed tomography angiography (CCTA), according to smoking status, and determine whether ex-smokers share a low probability of developing CAD with never-smokers. We retrospectively enrolled 6930 self-referred asymptomatic adults who underwent both coronary artery calcium score (CACS) and CCTA. The prevalence and characteristics of SCA were assessed according to smoking status (never-, ex- and current smokers). After adjusting for variable risk factors, we used multivariate logistic regression for adjusted odds ratios (AOR) of high CACS (>100), SCA (any plaque), significant stenosis (>50 % in luminal stenosis) and each plaque type (non-calcified, mixed and calcified plaque) among the three groups. The prevalence of SCA was highest in the ex-smokers (35.4 %) and the prevalence of significant stenosis in ex-smokers (6.9 %) was as high as in current smokers (6.4 %). However, after adjusting for variable risk factors, SCA was significantly correlated with both ex-smokers (AOR; 1.21) and current smokers (AOR; 1.25), whereas significant stenosis was correlated only with current smokers (AOR; 1.91). The association between SCA and ex-smokers is as strong as with current smokers, although significant stenosis is only correlated with current smokers; thus, not only quitting smoking but also never initiating smoking would be helpful to reduce the progression of the SCA.

    Objective The World Health Organization (WHO) reports that nonsmokers experience disease and death due to secondhand smoke (SHS) exposure in the home. We estimated the total excess burden and costs to society due to SHS exposure in U.S. public housing. Methods We quantified the public health burden for outcomes causally related to SHS exposure for nationally representative never-smoking residents in U.S. public housing using (1) WHO-recommended health outcomes and methodology, (2) publicly available and other large databases, and (3) published estimates of morbidity and mortality rates. We used published estimates of direct medical and nonmedical care costs and the value of productivity losses to estimate SHS-related societal costs for disease and death. We estimated the public health and economic burden for two serum cotinine limits of detection (LODs): 0.05 nanograms per milliliter (ng/mL) and 0.015 ng/mL. Results In 2011, an estimated 37,791 never-smoking child and adult U.S. public housing residents experienced illness and death due to SHS exposure at home based on an LOD=0.05 ng/mL (50,967 residents at LOD=0.015 ng/mL). Costs incurred by society for these illnesses and deaths totaled $183 million (LOD=0.05 ng/mL) and $267 million (LOD=0.015 ng/mL) annually. Of the total costs, direct costs (medical and nonmedical) accounted for $128 million and $176 million for LOD=0.05 ng/mL and LOD=0.015 ng/mL, respectively. Medical care accounted for the majority of direct costs—$110 million at LOD=0.05 ng/mL and $153 million at LOD=0.015 ng/mL. Adverse respiratory health outcomes accounted for approximately one-half (56% at LOD=0.05 ng/mL and 52% at LOD=0.015 ng/mL) of total societal costs. Conclusion Implementing smoke-free policies in all U.S. public housing could save lives and decrease SHS-related morbidity and mortality in never-smoking residents, resulting in annual societal savings of $183 million at LOD=0.05 ng/mL and $267 million at LOD=0.015 ng/mL.

    The health effects associated with Asian dust have attracted attention due to the rapid increase in the number of Asian dust events in East Asia in recent years. The aim of this study was to investigate the associations between Asian dust and daily cough, as well as allergic symptoms, in adult patients who suffer from chronic cough. We enrolled 86 adult patients from Kanazawa University Hospital, Japan, who were diagnosed with asthma, cough variant asthma, atopic cough or a combination of these conditions. From January to June 2011, subjects recorded their symptoms in a diary every day. Asian dust and non-Asian dust periods were defined according to the dust extinction coefficient, measured using the light detection and ranging (LIDAR). The daily levels of total suspended particulates, polycyclic aromatic hydrocarbons (PAHs) and coexisting factors related to allergies, such as the Japanese cedar pollen count, were measured. McNemar's test showed that there were significantly more cough-positive patients during Asian dust periods than during the non-Asian dust period (p = 0.022). In addition, during Asian dust periods when the daily levels of Japanese cedar pollen, Japanese cypress pollen and PAHs were elevated, there were significantly more patients who experienced itchy eyes than during the non-Asian dust period (p < 0.05). On the other hand, there were no significant differences in the allergic symptoms, including sneezing or a runny nose and nasal congestion. This is the first report to show that Asian dust triggers cough and allergic symptoms in adult patients with chronic cough.

    A sensitive and simple liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for simultaneous determination of nicotine and its main metabolite cotinine in human serum samples. Liquid-liquid extraction using ethyl acetate was employed for serum sample extractions. Chromatographic separation was achieved on Phenomenex Luna(®) HILIC column (150 mm x 3.0mm, 5 μm). Isocratic elution was performed using acetonitrile:100mM ammonium formate buffer (pH=3.2) (90:10, v/v) as the mobile phase, at a flow rate of 0.4 mL/min. Tandem mass spectrometric detection was employed at positive electrospray ionization in MRM mode for the determination of both nicotine and cotinine and their stable isotope labeled internal standards. Analysis was carried out in 8 min over a concentration range of 0.26-52.5 ng/mL and 7.0-1500 ng/mL for nicotine and cotinine, respectively. The assay was validated according to FDA guidelines for bioanalytical method validation and satisfactory results were obtained; the accuracy ranged between 93.39% and 105.73% for nicotine and between 93.04% and 107.26% for cotinine. No significant matrix effect was observed. Stability assays indicated both nicotine and cotinine were stable during sample storage, preparation and analytical procedures. The method was successfully applied to biological samples obtained from a pharmacokinetic study conducted in adult smokers to investigate heat effect on nicotine and cotinine serum levels after nicotine transdermal delivery system (TDS) application.

    Little is known about effective methods to recruit unmotivated smokers into cessation induction trials, the reasons unmotivated smokers agree to participate, and the impact of those reasons on study outcomes. A mixed-method approach was used to examine recruitment data from a randomized controlled cessation induction trial that enrolled 255 adult smokers with low motivation to quit. Over 15 months, 33% of smokers who inquired about the study were enrolled. Common recruitment methods included word-of-mouth, print advertisements and clinic referrals. Frequently mentioned reasons for participating included to: gain financial incentives (44.7%), learn about research or help others quit (43%), learn about smoking and risks (40%) and help with future quits (i.e. Quit Assistance, 23.9%). Separate regression models predicting study outcomes at 26 weeks indicated that smokers who said they participated for Quit Assistance reported higher motivation to quit (B 1.26) and were more likely to have made a quit attempt (OR 2.03) compared to those not mentioning this reason, when baseline characteristics were controlled. Understanding reasons for unmotivated smokers' interest in treatment can help practitioners and researchers design effective strategies to engage this population. PMID:27081187

    Using online survey data from a large sample of adults with autism spectrum disorder and legal guardians, we first report outcomes across a variety of contexts for participants with a wide range of functioning, and second, summarize these stakeholders' priorities for future research. The sample included n = 255 self-reporting adults with autism spectrum disorder aged 18-71 years (M = 38.5 years, standard deviation = 13.1 years) and n = 143 adults with autism spectrum disorder aged 18-58 years (M = 25.0 years, standard deviation = 8.2 years) whose information was provided by legal guardians. Although the self-reporting subsample had much higher rates of employment, marriage/partnership, and independent living than are typically seen in autism spectrum disorder outcome studies, they remained underemployed and had strikingly high rates of comorbid disorders. Data on both descriptive outcomes and rated priorities converged across subsamples to indicate the need for more adult research on life skills, treatments, co-occurring conditions, and vocational and educational opportunities. Stakeholders also placed priority on improving public services, health care access, and above all, public acceptance of adults with autism spectrum disorder. Findings must be interpreted in light of the self-reporting subsample's significant proportion of females and of later-diagnosed individuals. This study underscores the need for lifespan research; initiatives will benefit from incorporating information from the unique perspectives of adults with autism spectrum disorder and their families.

    Web-assisted tobacco interventions (WATI) have proliferated in recent years, but little is known about those such sites are reaching and those who might be reached in the future. A better understanding of factors that differentiate smokers who do and do not use the Internet could help developers of smoking cessation resources optimize the content and dissemination of resources to these two groups. Using the 2003 Health Information National Trends Survey (HINTS), a nationally representative survey of U.S. adults, we compared smokers using the Internet (n=728) with smokers not using the Internet (n=516) on demographics, smoking history, healthcare (status, care, access, and use), beliefs about lung cancer risks, and media preferences. Our results showed that compared with smokers not on the Internet, those using the Internet had a higher income and were more likely to be employed, despite having a younger age. Internet-connected smokers also reported less psychological distress, fewer barriers to healthcare, and a greater interest in quitting smoking. Preferences for media also differed by Internet status: Those on the Internet spent less time on television and more time with newspapers and magazines than those not on the Internet. These and other differences may assist the public health community with both the design and dissemination of resources to help smokers quit.

    Different aspects of the daily movement pattern--sitting, light intensity physical activity, and moderate- and vigorous intensity physical activity--have each independently been associated with health and longevity. Previous knowledge of the amount and distribution of these aspects in the general Swedish population, as well as the fulfilment rate of physical activity recommendations, mainly relies on self-reported data. More detailed data assessed with objective methods is needed. The aim of the study was to present descriptive data on the daily movement pattern in a middle-aged Swedish population assessed by hip-worn accelerometers. The cohort consisted of 948 participants (51% women), aged 50 to 64 years, from the Swedish CArdioPulmonary bioImage pilot Study. In the total sample, 60.5% of accelerometer wear time was spent sitting, 35.2% in light physical activity and 3.9% in moderate- and vigorous physical activity. Men and participants with high educational level spent a larger proportion of time sitting, compared to women and participants with low educational level. Men and participants with a high educational level spent more time, and the oldest age-group spent less time, in moderate- and vigorous physical activity. Only 7.1% of the study population met the current national physical activity recommendations, with no gender, age or education level differences. Assessment of all three components of the daily movement pattern is of high clinical relevance and should be included in future research. As the fulfilment of national physical activity recommendations is very low and sitting time is very high in our middle-aged population, the great challenge remains to enhance the implementation of methods to increase the level of physical activity in this population.

    This pilot study was conducted to explore the associations between stressors related to homelessness and modifiable health risk factors (poor diet, insufficient physical activity, and overweight/obesity) and to provide direction for future research. Participants (N = 57) were homeless adults enrolled in a smoking cessation program. Analyses were conducted to characterize the sample as well as the relations between relevant stressors (discrimination, chronic stress, and fear and mistrust) and health risk factors. Inadequate daily consumption of fruits, vegetables, and fiber was common. High-fat diet and insufficient physical activity were also prevalent, and the majority of participants were overweight/obese. Participants commonly endorsed discrimination, fear of victimization, mistrust of others, and several other stressors. Greater endorsement of stressors was associated with a high-fat diet. Results suggest that lifestyle interventions and policy changes may be warranted in homeless shelters to attenuate the potential effects of stressors on high-fat dietary consumption among smokers.

    In the evolving landscape of tobacco use, it remains unclear how tobacco control efforts should be designed and promoted for maximum impact. The current study links the identification of latent classes of young adult combustible tobacco users with anticipated responses to graphic health warning labels (HWLs). Data were collected in January 2012 using an online address-based panel as part of the Legacy Young Adult Cohort Study, and analyses were conducted in 2013. Latent class analyses identified five groups of tobacco users in a national sample of 4,236 young adults aged 18-34years: (1) little cigar/cigarillo/bidi (LCC) and hookah users (4%); (2) nonusers, open to smoking (3%); (3) daily smokers who self-identify as "smokers" (11%); (4) nondaily, light smokers who self-identify as "social or occasional smokers" (9%); and (5) nonusers closed to smoking (73%). Of the nonusers closed to smoking, 23% may be better characterized as at risk for tobacco initiation. Results indicate differences in the potential effectiveness of HWLs across classes. Compared to the daily "smokers," LCC and hookah users (RRR=2.35) and nonusers closed to smoking (RRR=2.33) were more than twice as likely to report that new graphic HWLs would make them think about not smoking. This study supports the potential of graphic HWLs to prevent young nonusers from using tobacco products. It suggests that the extension of prominent HWLs to other tobacco products, including LCCs and hookah tobacco, may also serve a prevention function. PMID:25437268

    Adults with metabolic syndrome from different race/ethnicities are often predisposed to developing type 2 diabetes (T2D); however, growing evidence suggests that healthy diets and lifestyle choices can significantly slow or prevent progression to T2D. This poorly understood relationship to healthy dietary patterns and prevention of T2D motivated us to conduct a retrospective analysis to determine the potential impact of a minor dietary lifestyle change (daily mushroom consumption) on known T2D risk factors in racially diverse adults with confirmed features of the metabolic syndrome. Retrospectively, we studied 37 subjects who had participated in a dietary intervention focused on vitamin D bioavailability from white button mushrooms (WBM). All 37 had previously completed a 16-week study where they consumed 100 g of WBM daily and were then followed-up for one month during which no mushrooms were consumed. We analyzed differences in serum risk factors from baseline to 16-week, and from baseline to one-month follow-up. Measurement of serum diabetic risk factors included inflammatory and oxidative stress markers and the antioxidant component naturally rich in mushrooms, ergothioneine. Significant beneficial health effects were observed at 16-week with the doubling of ergothioneine from baseline, increases in the antioxidant marker ORAC (oxygen radical absorption capacity) and anti-inflammatory hormone, adiponectin and significant decreases in serum oxidative stress inducing factors, carboxymethyllysine (CML) and methylglyoxal (MG), but no change in the lipid oxidative stress marker 8-isoprostane, leptin or measures of insulin resistance or glucose metabolism. We conclude that WBM contain a variety of compounds with potential anti-inflammatory and antioxidant health benefits that can occur with frequent consumption over time in adults predisposed to T2D. Well-controlled studies are needed to confirm these findings and identify the specific mushroom components

    Smoking is a worldwide public health problem, and various communication strategies aimed at its cessation have been used. The objective of this paper was to explore differences over time of two communication strategies (gain-framed versus loss-framed) in encouraging calls to a Quitline, according to smoker's degree of dependence. A study was conducted for four weeks among passengers of two selected subway stations in the city of Rio de Janeiro-Brazil (N(average) = 12,500 passengers a day per station). The interventions - large posters with images and text based on central theme "shortness-of-breath" - also contained the Quitline number. Call rate differences between the strategies, overall and specific per study week, were calculated. Light smokers exposed to the positive-content message called on average 2.2 times more often than those exposed to the negative-content message (p < 0.001). The absolute difference in call rates decreased after the first week of the study (p for the additive interaction between intervention and study week, 0.02). For heavy smokers, no differences between the two stations were observed. Additive interaction was found between type of smoker - light or heavy - and intervention (p = 0.02). The results suggest that short-term positive-content campaigns based on issues pertaining to individuals' daily routine could be effective in capturing light smokers. These results may have considerable public health impact, as the prevalence of less dependent smokers is much higher than that of heavier smokers. PMID:20163919

    Nondaily, or intermittent smokers (ITS), represent a growing pattern in adult smoking that needs to be explained by models of drug dependence. ITS regularly and voluntarily abstain from smoking, yet have difficulty quitting. We examine potential accounts of ITS' smoking by exploring their experience of craving and withdrawal on the days they abstain. For 3 weeks, 146 ITS and 194 daily smokers used the Ecological Momentary Assessment (EMA) to monitor craving, withdrawal, and smoking in real-time. ITS' craving (p < .001) and arousal (p < .001) were significantly lower on the 34.4% of days when they abstained (compared with days they smoked), and they experienced no increases in withdrawal symptoms. ITS who abstained for longer experienced lower craving, even on their first day of abstinence (p < .001). Within strata defined by longest duration of abstinence (1, 2-3, 4-6, ≥7 days), craving did not change over time, demonstrating no increase as resumption of smoking approached. Craving increased only at the moment smoking resumed. Furthermore, duration of abstinence runs varied more within persons than across persons. These findings contradict the predictions of a model positing that craving recurs at fixed intervals. Findings are consistent with the hypothesis that ITS' smoking is cued or primed by particular stimuli rather than by temporal cycles. These analyses demonstrate that ITS do not experience increased craving or withdrawal on days they do not smoke, and show neither signs of classical dependence nor regular cycles of craving and smoking.

    Vitamin D is essential regarding several health outcomes. Prevention of insufficiency (25-hydroxyvitamin D concentration ≤20 ng/mL) generally entails blood testing and/or supplementation, strategies that should target at-risk individuals because blood testing is costly, and unwarranted supplementation could result in vitamin D overload with unknown long-term consequences. Our objective was to develop a simple score (Vitamin D Insufficiency Prediction score, VDIP) for identifying adults at risk of vitamin D insufficiency. Subjects were 1557 non-vitamin D-supplemented middle-aged adults from the SU.VI.MAX cohort. Scoring points corresponded to the rounded odds ratio for each individual-level characteristic associated with vitamin D insufficiency in a multivariable logistic regression model. Receiver operating characteristic curve (area under curve), sensitivity, specificity, and positive and negative predictive values were computed. External validation was performed in an independent cohort (NutriNet-Santé, N = 781). For female sex, overweight, low physical activity, winter season, moderate sun exposure, and very fair or dark skin 1.5 points were attributed; 2 points for latitude ≥48°N and spring season; 2.5 points for obesity and late winter; 3 points for low sun exposure. Points were then summed up for each participant. The VDIP score had an AUC = 0.70 ± 0.01 (validation: 0.67 ± 0.02). With a score of 7 or more, 70% of the participants were vitamin D-insufficient (80% in those with a score ≥9), sensitivity/specificity were 0.67/0.63, and positive and negative predictive values were 0.70/0.59. The VDIP score performed well in identifying middle-aged adults at risk of vitamin D insufficiency (score ≥7, moderate risk; score≥9, high risk), using only simple individual-level characteristics easily assessable in day-to-day clinical practice. Implementation of this simple and costless score could thus obviate unwarranted supplementation and

    Recent research has underscored the importance of assessing barriers to smokers' acceptance of cessation programs. This paper illustrates the use of computer simulations to gauge smokers' response to program modifications which may produce barriers to participation. It also highlights methodological issues encountered in conducting this work. Computer simulations were based on conjoint analysis, a consumer research method which enables measurement of smokers' relative preference for various modifications of cessation programs. Results from two studies are presented in this paper. The primary study used a randomly selected sample of 218 adult smokers who participated in a computer-assisted phone interview. Initially, the study assessed smokers' relative utility rating of 30 features of cessation programs. Utility data were used in computer-simulated comparisons of a low-cost, self-help oriented program under development and five other existing programs. A baseline version of the program under development and two modifications (for example, use of a support group with a higher level of cost) were simulated. Both the baseline version and modifications received a favorable response vis-à-vis comparison programs. Modifications requiring higher program costs were, however, associated with moderately reduced levels of favorable consumer response. The second study used a sample of 70 smokers who responded to an expanded set of smoking cessation program features focusing on program packaging. This secondary study incorporate in-person, computer-assisted interviews at a shopping mall, with smokers viewing an artist's mock-up of various program options on display. A similar pattern of responses to simulated program modifications emerged, with monetary cost apparently playing a key role. The significance of conjoint-based computer simulation as a tool in program development or dissemination, salient methodological issues, and implications for further research are discussed

    In this study, the protective effect of quercetin was evaluated against arsenic induced reproductive ailments in male rats. For this purpose, male rats (n = 5/group) weighing 180-250 g were used. First group served as control, second group received arsenic (50 ppm) in drinking water. Third group was treated with quercetin (50 mg/kg) alone, while fourth group received arsenic + quercetin. All treatments were carried out for 49 days. After treatment, animals were killed by decapitation; testis and epididymis were dissected out. Right epididymis was minced immediately for comet assay, while left epididymis was processed for histology. Similarly, right testis was homogenized for estimation of daily sperm production (DSP) and detection of metal concentration. The results of our research revealed that arsenic treatment did not cause any significant change in body weight and testicular volume. Quercetin treatment significantly prevented tissue deposition of arsenic within the testis. Arsenic treatment caused a significant reduction in DSP, however, in the arsenic + quercetin-treated group and quercetin alone-treated group, DSP was significantly high as compared to the arsenic-treated group. Histological study of epididymis showed empty lumen in arsenic-treated group while in arsenic + quercetin-treated group and quercetin alone-treated group, lumen were filled with sperm and were comparable to control. Sperm DNA damage, induced by arsenic, was significantly reversed toward control levels by supplementation of quercetin. These results suggest that quercetin not only prevents deposition of arsenic in tissues, but can also protect the sperm DNA damage.

    Background In an attempt to minimize the pack design avenue of communication between tobacco producers and smokers and potential smokers, several jurisdictions, including Norway, have considered regulations on cigarette pack design. The main aim of the current study was to investigate how package design affects young people’s perceptions of typical smokers of some pre-chosen cigarette brands and brand varieties. Methods Based on data from a web survey among 1022 15–22 year-olds, possible effects of plain packaging of cigarettes on adolescents’ views about typical cigarette smokers were investigated. The data collection had a between-subjects design, in which participants were allocated to one of three groups, and asked to typify the smokers of selected cigarette packs either in branded, plain or plain with descriptor versions. The sample included boys and girls, and smokers and non-smokers. The smoker characteristics included in the investigation were: gender, glamour, stylishness, popularity, coolness, sophistication and slimness. Results After creating sum-scores within and across packs and pack versions, analyses indicated that a shift from branded to plain cigarette packaging would result in a reduction in positive user images related to smoking among adolescents and young adults. For girls, this effect held up after controlling for confounders. Conclusions To the extent that plain packaging contributes to making smoking images less positive, it can potentially be an efficient aid in reducing smoking uptake among adolescents. PMID:24156515

    Abstract Background Baseline characteristics from the adult cohort of a randomized controlled trial comparing sensor-augmented pump (SAP) and multiple daily injection (MDI) therapy were analyzed for significant relationships with −0.5% A1C change at 1 year of therapy without incidence of severe hypoglycemia (defined as A1C benefit). Methods Baseline characteristics were compared with A1C benefit. Statistically significant predictors were analyzed further to determine appropriate cutpoints of relative A1C benefit. Results Baseline A1C ≥9.1%, age at randomization ≥36 years, and age at diabetes diagnosis of ≥17 years were associated with a greater SAP benefit relative to MDI than other cutpoints. Conclusions People with type 1 diabetes who had a high A1C and who were older at diagnosis and older at randomization experienced the most benefit from SAP therapy. PMID:21488717

    Background February 2013 US treatment guidelines recommend the once-daily tablet of efavirenz/emtricitabine/tenofovir (Atripla®) as a preferred regimen and the once-daily tablet of elvitegravir/cobicistat/emtricitabine/tenofovir (Stribild™) as an alternative regimen for first-line treatment of human immunodeficiency virus (HIV). This study assessed the clinical and economic trade-offs involved in using Atripla compared with Stribild as first-line antiretroviral therapy in HIV-infected US adults. Methods A Markov cohort model was developed to project lifetime health-related outcomes, costs, quality-adjusted life years (QALYs), and cost-effectiveness of Stribild compared with Atripla as first-line antiretroviral therapy in HIV-1-infected US patients. Patients progressed in 12-week cycles through second-line, third-line, and nonsuppressive therapies, acquired immune deficiency syndrome, and death. Baseline characteristics and first-line virologic suppression, change in CD4 count, and adverse effects (lipid, central nervous system, rash, renal) were based on 48-week clinical trial results. These results demonstrated equivalent virologic suppression between the two regimens. Point estimates for virologic suppression (favoring Stribild) were used in the base case, and equivalency was used in the scenario analysis. Published sources and expert opinion were used to estimate costs, utilities, risk of acquired immune deficiency syndrome, mortality, subsequent-line CD4 count, clinical efficacy, and adverse events. Costs were reported in 2012 US dollars. Sensitivity analyses were conducted to assess robustness of results. Results Compared with patients initiating Atripla, patients initiating Stribild were estimated to have higher lifetime costs. Stribild added 0.041 QALYs over a lifetime at an additional cost of $6,886, producing an incremental cost-effectiveness ratio of $166,287/QALY gained. Results were most sensitive to first-line response rates, product costs, and

    This study aimed to examine whether daily intake of citrus juice containing heat-killed Lactobacillus plantarum YIT 0132 (LP0132-fermented juice) alleviates symptoms of atopic dermatitis. This was a natural extension of our previous study in which LP0132 was shown to enhance IL-10 production in vitro and LP0132-fermented juice was found to alleviate symptoms and enhance quality of life (QOL) in patients with Japanese cedar pollinosis. In two open trials, Trial 1 and Trial 2, 32 and 18 adult patients with mild to moderate atopic dermatitis consumed LP0132-fermented juice for 8 weeks. Skin conditions and QOL were subjectively evaluated using Skindex-16 before intake of the juice (Pre-treatment), 8 weeks after starting intake (Treatment) and 8 weeks after termination of intake (Post-treatment). Blood parameters were also analyzed. Comparison of the Treatment and Post-treatment time points with the Pre-treatment time point revealed significant reductions in the Skindex-16 overall score and the 3 domain subscores (symptoms, emotions, and functioning domains) in both trials. Moreover, blood levels of eosinophil cationic protein (ECP), total immunoglobulin E (IgE) and specific IgEs for Japanese cedar and cypress pollen were significantly attenuated in Trial 2. The findings suggest that daily intake of citrus fermented juice containing heat-killed LP0132 has beneficial effects on symptoms and QOL in patients with mild to moderate atopic dermatitis due to an immunomodulatory effect via attenuation of IgE and ECP.

    The duration of the seminiferous epithelium cycle was estimated in adult maned wolves (Chrysocyon brachyurus, Illiger, 1811), by applying intratesticular injections with tritiated thymidine. The total duration of the seminiferous epithelium cycle in this species was calculated in 8.99 days. So, taking into account that approximately 4.5 cycles of the seminiferous epithelium are necessary for the whole spermatogenesis process to complete, the production of spermatozoa from one spermatogonia will take about 40.45 days. The duration of the spermiogenesis was calculated to be 12.3 days. The eight stages of the seminiferous epithelium cycle were described by the tubular morphology method, which is based either on the form and position of the spermatid nuclei and the occurrence of meiotic divisions. The values of the relative frequency for the pre-meiotic, meiotic and post-meiotic phases in this species were 3.5, 0.78 and 4.8 days, respectively. The maned wolf produces about 29 million spermatozoa a day for each testis gram, therefore being classified among the species provided with a high spermatogenetic efficiency.

    The colon microbiota plays a crucial role in human gastrointestinal health. Current attempts to manipulate the colon microbiota composition are aimed at finding remedies for various diseases. We have recently described the immunomodulatory effects of three probiotic strains (Lactobacillus rhamnosus CNCM I-4036, Lactobacillus paracasei CNCM I-4034, and Bifidobacterium breve CNCM I-4035). The goal of the present study was to analyze the compositions of the fecal microbiota of healthy adults who received one of these strains using high-throughput 16S ribosomal RNA gene sequencing. Bacteroides was the most abundant genus in the groups that received L. rhamnosus CNCM I-4036 or L. paracasei CNCM I-4034. The Shannon indices were significantly increased in these two groups. Our results also revealed a significant increase in the Lactobacillus genus after the intervention with L. rhamnosus CNCM I-4036. The initially different colon microbiota became homogeneous in the subjects who received L. rhamnosus CNCM I-4036. While some orders that were initially present disappeared after the administration of L. rhamnosus CNCM I-4036, other orders, such as Sphingobacteriales, Nitrospirales, Desulfobacterales, Thiotrichales, and Synergistetes, were detected after the intervention. In summary, our results show that the intake of these three bacterial strains induced changes in the colon microbiota. PMID:26016655

    Introduction: Research has documented growing availability and use of e-cigarettes in the United States over the last decade. Methods: We conducted a national panel survey of current adult cigarette smokers to assess attitudes, beliefs, and behaviors relating to e-cigarette use in the United States (N = 2,254). Results: Among current cigarette smokers, 20.4% reported current use of e-cigarettes on some days and 3.7% reported daily use. Reported reasons for e-cigarette use included: quit smoking (58.4%), reduce smoking (57.9%), and reduce health risks (51.9%). No significant differences in sociodemographic characteristics between e-cigarette users and nonusers were observed. Prior quit attempts were reported more frequently among e-cigarette users (82.8%) than nonusers (74.0%). Intention to quit was reported more frequently among e-cigarette users (64.7%) than nonusers (46.8%). Smokers intending to quit were more likely to be e-cigarette users than those not intending to quit (odds ratio [OR] = 1.90, CI =1.36–2.65). Those who used e-cigarettes to try to quit smoking (OR = 2.25, CI = 1.25–4.05), reduce stress (OR = 3.66, CI = 1.11–12.09), or because they cost less (OR = 3.42, CI = 1.64–7.13) were more likely to report decreases in cigarette smoking than those who did not indicate these reasons. Smokers who reported using e-cigarettes to quit smoking (OR = 16.25, CI = 8.32–31.74) or reduce stress (OR = 4.30, CI = 1.32–14.09) were significantly more likely to report an intention to quit than those who did not indicate those reasons for using e-cigarettes. Conclusions: Nearly a quarter of smokers in our study reported e-cigarettes use, primarily motivated by intentions to quit or reduce smoking. These findings identify a clinical and public health opportunity to re-engage smokers in cessation efforts. PMID:25589678

    Daily personal exposures to benzo(a)pyrene (BaP) of 31 newsagents working in Genoa, Italy, were evaluated throughout 1998 during two different seasonal periods (February-April and May-June). Exposures of smoker and non-smoker subjects were compared. The highest BaP exposures were those of smokers during the cold period (2.20±0.84 ng/m 3). During this same period, the BaP exposure for non-smoker subjects was 1.00±0.32 ng/m 3. Both smoker and non-smoker exposures showed a seasonal dependence, with the lowest values occurring in the warm period (smokers: 1.46±0.72 ng/m 3, non-smokers: 0.65±0.25 ng/m 3). Compared to the cold period, the warm period produced a nearly 35% reduction in BaP exposures in both smoker and non-smoker subjects. A linear correlation was observed between personal exposures and number of cigarettes smoked daily. An increase in average daily BaP exposure of 0.071±0.009 ng/m 3 for every cigarette, due to passive smoke, was calculated. Mean BaP concentrations calculated from fixed monitoring stations were nearly 40% higher than mean personal exposures of non-smoker newsagents.

    Adult male rhesus monkeys have a diurnal pattern of reproductive hormone secretion that is characterized by significantly elevated LH and testosterone secretion in the evening hours and a nadir in secretion of these hormones in the morning. To test the hypothesis that the daily pattern of food intake may play a role in regulating the diurnal pattern of reproductive hormone secretion we performed three studies. First, to determine the relationship between the timing of the diurnal rise in LH secretion and meal consumption, blood samples were collected from 13 adult male rhesus monkeys via chronically indwelling venous catheters (samples every 15-20 min from 0800-0800 h) while monkeys were maintained on the standard feeding regimen in our colony (one meal of Purina monkey chow fed between 1100 and 1200 h). On a day of normal feeding there was a significant diurnal rhythm in mean LH concentrations with elevated levels at night (nadir: 13.41 +/- 0.82 ng/ml from 0800-1100 h; peak: 21.34 +/- 1.56 ng/ml from 2000-2300 h, P < or = 0.05). The rising phase of the diurnal rhythm in LH secretion was apparent starting in the early afternoon, shortly after the daily meal, at 1400 h (5 h before lights went off at 1900 h), and the diurnal rise in LH secretion was no longer apparent by 0500 h (several hours before the lights went on at 0700 h). Second, we examined the influence of missing the daily meal on the diurnal pattern of LH and testosterone secretion. Blood samples were collected for a 24-h period on a day of fasting from 9 monkeys. On a day of fasting there was no diurnal rise in plasma LH or testosterone concentrations; plasma concentrations of these hormones remained at the low morning levels throughout the day. Third, we examined the diurnal pattern of LH and testosterone secretion after adapting 5 monkeys (for 6-8 weeks) to a new meal time that was 6 h later in the day than the standard meal time (i.e. at 1700 h). After adaptation to this later feeding time monkeys

    Adolescents who smoke are more likely to escalate their smoking frequency if they believe smoking is self-defining. Knowing factors that are associated with development of a smoker identity among adolescents who smoke may help to identify who will become a regular smoker. We investigated whether smoker identity development is associated with internal and external motives for smoking. For comparison, we also investigated whether social smoker identity development is associated with internal and external motives for smoking. Adolescents who smoke (n = 292) completed measures of smoker and social smoker identity, internal motives for smoking (negative affect coping, positive affect enhancement), and external motives for smoking (social fit) at baseline, 6-, 15-, and 24-month assessments of an ongoing longitudinal study of smoking patterns. We examined whether change in smoker and social smoker identity from 6 to 24 months was associated with change in motives at earlier assessment waves. We also explored whether gender moderated these relationships. Increases in negative affect coping motives were associated with smoker identity development among both males and females. Increases in social motives were associated with smoker identity development among males, and increases in negative affect coping motives were associated with social smoker identity development among females. Smoker and social smoker identities are signaled by negative affect coping as well as social motives for smoking. (PsycINFO Database Record PMID:27136374

    Background. Gait speed is as an important predictor of mortality, volume of medical care, hospitalization, onset of activities of daily living (ADL) disability, and nursing home placement. We examined associations between change in gait speed and change in observed performance in the instrumental ADL (IADL) in a sample of mild-to-moderately disabled older adults. Methods. Participants in the Sources of Independence in the Elderly project (n = 375) were approached to complete a 4-m gait assessment and a performance test of IADL competency at three points over 2 years. IADL competency was assessed by occupational therapists, who rated participants using the Assessment of Motor and Process Skills (AMPS) and who also made a global rating of need for help or supervision. Linear mixed models were developed to assess change in motor AMPS score relative to baseline status and change in gait speed and AMPS process scores. Results. Baseline gait and change in gait were significant correlates of change in the AMPS motor ability measures in models that adjusted for cognitive status and AMPS process ability. Even respondents with gait speeds of 1 m/s at baseline were at risk of declining AMPS motor ability and an occupational therapist rating of IADL disability if gait speed declined. Conclusions. Slowing in gait speed is an important risk factor for IADL disability in mild to moderately disabled older adults. PMID:24952575

    Aging and HIV are both risk factors for memory deficits and declines in real-world functioning. However, we know little about the profile of memory deficits driving instrumental activities of daily living (IADL) declines across the lifespan in HIV. This study examined 145 younger (<50 years) and 119 older (≥50 years) adults with HIV who completed the California Verbal Learning Test-Second Edition (CVLT-II), the Wechsler Memory Scale-Third Edition Logical Memory subtest (WMS-III LM), and a modified Lawton and Brody ADL questionnaire. No memory predictors of IADL dependence emerged in the younger cohort. In the older group, IADL dependence was uniquely associated with worse performance on all primary CVLT-II variables, as well as elevated recency effects. Poorer immediate and delayed recall of the WMS-III LM was also associated with IADL dependence, although recognition was intact. Findings suggest older HIV-infected adults with shallow encoding and forgetting are at risk for IADL dependence. PMID:24695591

    COPD (chronic obstructive pulmonary disease) is defined by a fixed expiratory airflow obstruction associated with disordered airways and alveolar destruction. COPD is caused by cigarette smoking and is the third greatest cause of mortality in the US. Forced expiratory volume in 1 second (FEV1) is the only validated clinical marker of COPD, but it correlates poorly with clinical features and is not sensitive enough to predict the early onset of disease. Using LC/MS global untargeted metabolite profiling of serum samples from a well-defined cohort of healthy smokers (n = 37), COPD smokers (n = 41) and non-smokers (n = 37), we sought to discover serum metabolic markers with known and/or unknown molecular identities that are associated with early-onset COPD. A total of 1,181 distinct molecular ions were detected in 95% of sera from all study subjects and 23 were found to be differentially-expressed in COPD-smokers vs. healthy-smokers. These 23 putative biomarkers were differentially-correlated with lung function parameters and used to generate a COPD prediction model possessing 87.8% sensitivity and 86.5% specificity. In an independent validation set, this model correctly predicted COPD in 8/10 individuals. These serum biomarkers included myoinositol, glycerophopshoinositol, fumarate, cysteinesulfonic acid, a modified version of fibrinogen peptide B (mFBP), and three doubly-charged peptides with undefined sequence that significantly and positively correlate with mFBP levels. Together, elevated levels of serum mFBP and additional disease-associated biomarkers point to a role for chronic inflammation, thrombosis, and oxidative stress in remodeling of the COPD airways. Serum metabolite biomarkers offer a promising and accessible window for recognition of early-stage COPD. PMID:26674646

    Despite the well-established adverse birth and childhood health outcomes associated with maternal smoking, smoking rates among pregnant women remain high. Psychosocial health attributes, including anxiety, depression, perceived stress, self-efficacy, and personality characteristics, have especially important roles in smoking behavior. Understanding who smokes during pregnancy and what factors influence this behavior choice may be key to improving the effectiveness of smoking cessation intervention programs. We use data from a prospective cohort study of pregnant women to understand the psychosocial health profiles of women who choose to smoke during pregnancy compared to the profiles of women who do not smoke or successfully quit smoking during pregnancy. Multinomial logistic regression analyses on 1518 non-Hispanic black and non-Hispanic white women assessed the association between smoking status and psychosocial health while controlling for demographic characteristics. Higher levels of perceived stress, depression, neuroticism, negative paternal support, and perceived racism among non-Hispanic blacks were associated with higher odds of being a smoker than a non-smoker (p<0.05). Higher levels of self-efficacy, extraversion, agreeableness, conscientiousness, interpersonal support, positive paternal support, and perceived social standing were associated with lower odds of being a smoker than a non-smoker (p<0.05). Our analysis indicates that women who smoked during pregnancy experienced a more negative constellation of psychosocial adversities than women who did not smoke. Given the psychosocial needs and personality profiles experienced by smokers, more attention to the psychosocial strengths and weaknesses of these women may allow for more tailored smoking cessation programs, enhancing both the short- and long-term effectiveness of such interventions.

    Pulmonary alveolar macrophages were obtained by saline lavage from 23 healthy male volunteers--10 non-smokers and 13 cigarette smokers. Lavage produced three times as many alveolar macrophages in smokers than in non-smokers. When macrophages from smokers and from non-smokers were incubated in vitro, more cells from smokers adhered to glass, spread out, and showed enhanced nitroblue tetrazolium (NBT) reduction. The surface morphology of alveolar macrophages from smokers showed more with a plate like appearance and ridge like membrane surface, while the macrophages from non-smokers were predominantly spherical with ruffles. The proportions of cells which stained highly for beta galactosidase were 55% in smokers and 11% in non-smokers. Thus, in a resting state in vitro, alveolar macrophages from smokers were more active than those from non-smokers. When, however, macrophages from smokers and non-smokers were incubated with immunobeads and with opsonised or non-opsonised BCG, the phagocytic activity and stimulated NBT reduction of alveolar macrophages from smokers were similar to or somewhat less than those of non-smokers.

    Introduction The strong relationship between persistent tobacco use and Major Depressive Disorder (MDD) has motivated clinical trials of specialized treatments targeting smokers with a history of MDD. Meta-analyses suggest positive responses to specialized treatments have been observed consistently among smokers with history of recurrent rather than a single episode of MDD. Approximately 15% of current US smokers have a history of recurrent MDD. Little is known about the risk factors that contribute to persistent smoking and differentiate these at-risk smokers. US. Methods The National Comorbidity Survey – Replication (NCS-R) included a survey of 1560 smokers participants aged 18 and older in the United States. Lifetime history of MDD was categorized according to chronicity: No History (No MDD), single episode (MDD-S) and recurrent depression (MDD-R). The relationship between the chronicity of MDD, smoking characteristics, cessation history, nicotine dependence, comorbidity with psychiatric disorders, and current functional impairments were examined. Results MDD-R smokers reported fewer lifetime cessation efforts, smoked more cigarettes, had higher levels of nicotine dependence, had higher rates of co-morbid psychiatric disorders and greater functional impairment than smokers with No MDD. MDD-S smokers were not consistently distinguished from No MDD smokers on cessation attempts, level of daily smoking, nicotine dependence or functional impairment indices. Conclusions The study highlights the importance of chronicity when characterizing depression related risk of persistent smoking behavior. Although, clinical trials suggest MDD-R smokers specifically benefit from specialized behavioral treatments, these services are not widely available and more efforts are needed to engage MDD-R smokers in efficacious treatments.

    The purpose of the current study was to establish measurement reliability in adults with Cerebral Palsy (CP), and to examine the feasibility and outcomes of an upper extremity strength training program (three times per week for 90 min each time). A control group design mixed with a prospective time series design for the intervention group was completed, including a pre-test, a post-test after a 12-week intervention period, and a follow-up in the intervention group after an additional 10-week period. Seventeen adults with CP with severe motor impairment took part in the study (10 in the intervention and seven in the control group). The test battery was comprised of wrist and hand dynamometry; dominant hand upper-extremity function measures (Jebsen Hand Function Test=JHFT, Minnesota Manual Dexterity Test=MMDT, and the Nine Hole Peg Test=NHPT); and activity of daily living with the Barthel Index. The results indicated that in both the control and the intervention groups, the strength tests exhibited good-to-excellent reliability during pre-test and post-test. The group comparison revealed that while in the pre-test no between-group differences existed, in the post-test the strength training group demonstrated significantly higher values in five out of eight strength measures, as well as in the MMDT. Discontinuing the program for eight weeks reversed the effects almost to baseline. In conclusion, the outcomes demonstrated the reliability of the assessments utilized in this study, as well as the feasibility of the strength training program, in adults with severe motor impairment due to CP.

  7. Daily consumption of a synbiotic yogurt decreases energy intake but does not improve gastrointestinal transit time: a double-blind, randomized, crossover study in healthy adults

    2013-01-01

    Objective Probiotic and synbiotic products are widely marketed to healthy individuals, although potential benefits for these individuals are rarely studied. This study investigated the effect of daily consumption of a synbiotic yogurt on gastrointestinal (GI) function in a sample of healthy adults. Subjects/Methods In a randomized crossover double-blind study, 65 healthy adults consumed 200 g/day of yogurt with (synbiotic) or without (control) added probiotics (Bifidobacterium lactis Bb12, Lactobacillus acidophilus La5, Lactobacillus casei CRL431) and 4 g inulin for two 15-day treatment periods, each preceded by a 6-week washout period. GI transit time (GTT), duration of colour (DOC), GI symptoms and dietary intake were assessed and analyzed using repeated measures ANOVA, including PRE-treatment GTT as a covariate. Participants were grouped as short GTT (STT, n = 50, ≤32.7 h) or long GTT (LTT, n = 15, >32.7 h) based on their PRE-treatment GTT assessment. Results POST-treatment GTT and DOC were not different between synbiotic and control, and did not change from PRE-treatment, within the STT or LTT groups. There were no changes in GI symptom ratings, indicating that both yogurts were well tolerated. In STT, energy, fat and protein intakes were decreased from baseline with synbiotic (p = 0.055, p = 0.059 and p = 0.005, respectively) and dietary fibre intake was higher POST-treatment with synbiotic versus control (p = 0.0002). In LTT, decreases in energy and fat intakes with synbiotic were not significant (p = 0.14 and p = 0.18, respectively) and there were no differences in dietary fibre intake. Conclusion Consuming 200 g/day of synbiotic yogurt did not significantly alter GTT in healthy adults, but was well tolerated and helped to reduce overall energy intake. PMID:23787118

    In a sample of 200 subjects, representative of a population of 1936 civil servants, we tested differences in life style, dietary habits and distribution of risk factors for CHD between smokers and nonsmokers. The two groups (79 smokers) and (121 non-smokers) did not differ significantly by age or sex. The percentage of sedentary subjects, of hypercholesterolaemics and of hypertensives was found to be particularly high among smokers: 67%, 33% and 30% respectively (vs 59%, 27% and 19% in non-smokers). More smokers were obese (11% vs 5%) but mean BMI was the same in smokers/non-smokers but showed a higher fat mass; the association of CHD risk factors indicates only one significant correlation (P < 0.05) between obesity and hypertension. In male smokers, higher values of LDL and triglycerides and lower intake of energy, vitamins C and A are observed and these values are significantly different than those for non-smokers. In women HDL values are higher in non-smokers whereas, in female smokers, the food cholesterol intake is particularly high 271 +/- 295 mg. There are also correlations both for the anthropometric and clinical parameters and for energy and nutrients, indicating that the lifestyle of smokers is less healthy than that of non-smokers. Smokers cat vegetables and fruits less frequently and consume more alcohol than non-smokers, who prefer sweet foods.

    One out of two smokers who smoke throughout their lifetime will die from a disease related to smoking. Tobacco smoking therefore represents a major global public health issue. Smoking is the leading cause of chronic obstructive pulmonary disease (COPD). Projections for 2020 indicate that by then, COPD will have become the third cause of death and the fifth cause of disability worldwide. Stopping smoking reduces the risk of developing COPD and is an essential treatment for this inflammatory disease. Smoking cessation decreases the prevalence of respiratory symptoms, number of hospitalizations, and decline in FEV1, as well as exacerbation frequency and overall mortality. Among the patients, 38-77% with COPD are smokers. Their daily cigarette consumption and level of nicotine dependence are often high. The combination of high intensity behavioral interventions and medication treatments (nicotine replacement therapy, varenicline, bupropion) is the most effective strategy for smokers with COPD. In contrast, behavioral interventions without medication are not more effective than simple advice to stop. Two factors seem to predict the success of the attempt to quit in smokers with COPD: a strong motivation to quit and the use of smoking cessation medications.

    Objective To investigate the role of the tobacco industry in marketing to and sustaining tobacco addiction among older smokers and aging Baby Boomers. Methods Archival searches of electronic archives of internal tobacco company documents using a snowball sampling approach. Analysis utilizing iterative and comparative review of documents, classification by themes, and a hermeneutic interpretive approach to develop a case study. Results Based on extensive marketing research, tobacco companies aggressively targeted older smokers and sought to prevent them from quitting. Innovative marketing approaches were used. “Low tar” cigarettes were developed in response to the health concerns of older smokers, despite industry knowledge that such products had no health advantage and did not help smokers quit. Conclusion Tobacco industry activities influence the context of cessation for older smokers in several ways. Through marketing “low-tar” or “light” cigarettes to older smokers at risk at quitting, the industry contributes to the illusion that such cigarettes are safer; however, “light” cigarettes may actually make it harder for addicted smokers to quit. Through targeted mailings of coupons and incentives, the industry discourages older smokers from quitting. Through rhetoric aimed at convincing addicted smokers that they alone are responsible for their smoking, the industry contributes to self-blame, a documented barrier to cessation. Educating practitioners, older smokers and families about the tobacco industry’s influence may decrease the tendency to “blame the victim,” thereby enhancing the likelihood of tobacco addiction treatment for older adults. Comprehensive tobacco control measures must include a focus on older smokers. PMID:18691279

    Background: Smoking is a major public health problem, especially in Iraq. There is very little information had been documented regarding smoking risk factors and quit intention among Iraqi smokers. Objectives: The main objectives of this study are to determine smokers' knowledge and perception about smoking health risks; and to determine smoking behavior and quitting intentions among Iraqi smokers; as well as to predict the factors that may associate with quit intentions. Methods: A cross-sectional study was conducted at the outpatient clinic in Tikrit Teaching Hospital, Tikrit City, Iraq. Adult smokers who are smoking cigarette everyday and able to communicate with the researcher were invited to participate in the study. A self-administered questionnaire was used to collect data from 386 participants. Results: This study showed that smokers had low awareness about some risk effects of smoking such as lung cancer in nonsmokers (30.1%), impotence in male smokers (52.6%), premature ageing (64%), and stroke (66.3%). In addition, the high score of knowledge and perception was significantly associated with quitting intention. Conclusion: Smokers' knowledge and perception regarding smoking health effects were low, especially in terms of secondhand smokers. Many efforts needed from health policy-makers and health care professionals to disseminate information about the risks of smoking and health benefits of give up smoking. PMID:27134468

    Objective To synthesise estimates of the prevalence of cessation attempts among adolescent smokers generally, and according to age and level of cigarette consumption. Data sources PubMed, ERIC, and PsychInfo databases and Internet searches of central data collection agencies. Study selection National population‐based studies published in English between 1990 and 2005 reporting the prevalence, frequency and/or duration of cessation attempts among smokers aged ⩾10 to <20 years. Data extraction Five reviewers determined inclusion criteria for full‐text reports. One reviewer extracted data on the design, population characteristics and results from the reports. Data synthesis In total, 52 studies conformed to the inclusion criteria. The marked heterogeneity that characterised the study populations and survey questions precluded a meta‐analysis. Among adolescent current smokers, the median 6‐month, 12‐month and lifetime cessation attempt prevalence was 58% (range: 22–73%), 68% (range 43–92%) and 71% (range 28–84%), respectively. More than half had made multiple attempts. Among smokers who had attempted cessation, the median prevalence of relapse was 34, 56, 89 and 92% within 1 week, 1 month, 6 months, and 1 year, respectively, following the longest attempt. Younger (age<16 years) and non‐daily smokers experienced a similar or higher prevalence of cessation attempts compared with older (age ⩾16 years) or daily smokers. Moreover, the prevalence of relapse by 6 months following the longest cessation attempt was similar across age and smoking frequency. Conclusions The high prevalence of cessation attempts and relapse among adolescent smokers extends to young adolescents and non‐daily smokers. Cessation surveillance, research and program development should be more inclusive of these subgroups. PMID:18048598

    This study investigated the effects of leisure and social activities on the ability of middle-aged adults to maintain activities of daily living (ADL), and whether performing these activities alone or with others contributed to the ability to perform ADL. The study used nationally representative longitudinal data of 22,770 adults in Japan, aged 50–59 years, who did not have limitations in performing ADL at the beginning of the 5-year survey period. The study considered six activity categories: two leisure activities (“hobbies or cultural activities” and “exercise or sports”) and four social activities (“community events,” “support for children,” “support for elderly individuals,” and “other social activities”). Multiple logistic regression analysis was used to examine the relation between participation in these categories at baseline and difficulties in ADL at the 5-year follow-up. The association between the extent of social interaction during these activities (“by oneself,” “with others,” or “both”) and difficulties in ADL was also investigated. The analysis yielded significant negative correlations between “exercise or sports” and difficulties in ADL for both men and women, and between “hobbies or cultural activities” and difficulties in ADL for women. However, these significant relationships occurred only when activities were conducted “with others.” The present findings might help prevent deterioration in middle-aged adults’ performance of ADL in Japan.

    Objective 24 h urinary sodium extretion was used to estimate the daily salt intake of shandong residents aged from 18 to 69 years in China. Setting 20 selected counties/districts in Shandong stratified by geographic region (Eastern, Central Southern and North Western) and residence type (urban vs rural). Participants Among 2184 randomly selected adults, 2061 provided usable 24 h urine samples. Urine volume <500 mL or male creatinine <3.81 (female creatinine <4.57) are not included in the analysis. Results The mean sodium level excreted over 24 h was 237.61 mmol (95% CI 224.77 to 250.44) mmol. Overall, the estimated mean salt intake was 13.90 g/day (95% CI 13.15 to 14.65). The mean salt intake among rural residents was higher than that among urban residents (14.00 vs 13.68 g; p<0.01). Salt intake in men was higher than that in women (14.40 vs 13.37 g; p<0.01). Approximately 96% of the survey participants had a dietary salt intake of ≥6 g/day. Conclusions The salt intake in Shandong is alarmingly higher than the current recommended amount (6 g/day). Thus, effective interventions to reduce salt intake levels to combat the increasing burden of non-communicable diseases need to be developed and implemented. PMID:25037642

    Human resource directorate employees of a large United Kingdom public hospital (N=36) completed an initial questionnaire and then participated in a daily diary study. The questionnaire included measures of affect and beliefs about high work demands' influence on affect and work performance. The diary included measures of affect, extent of high work demands, and daily beliefs, corresponding to those measured in the questionnaire. Participants were required to complete the diary twice daily, before and after work over a 2-week period. Measures of affect after work were associated with beliefs concerning work demands' influence on work performance and on affect measured after work. Beliefs about work demands measured in the questionnaire were associated with subsequent daily assessments of beliefs.

    Using ecological momentary assessment (EMA), we sought to determine whether differences in reporting would exist for smokers who self-monitored their smoking-related negative thoughts five times daily in comparison to a non-EMA control group. One hundred seventeen smokers were randomly assigned to two conditions. Eighty-eight smokers carried personal digital assistants (PDAs) for 2 weeks and monitored negative thoughts each day, and 29 smokers did not self-monitor their negative thoughts. All smokers completed pretest and posttest assessments reporting their perceived risk and worry associated with smoking consequences. The data revealed evidence of self-monitoring effects, as smokers in the EMA condition reported less worry after 2 weeks of self-monitoring compared to smokers in the control condition. The two conditions did not differ in their reports of perceived risk of smoking consequences. These data suggest that EMA procedures asking respondents to self-monitor their thoughts about smoking may influence feelings about their smoking behavior.

    Cigarette smoking is associated with various cutaneous disorders with defective permeability. Yet, whether cigarette smoking influences epidermal permeability barrier function is largely unknown. Here, we measured skin biophysical properties, including permeability barrier homeostasis, stratum corneum (SC) integrity, SC hydration, skin surface pH, and skin melanin/erythema index, in cigarette smokers. A total of 99 male volunteers were enrolled in this study. Smokers were categorized as light-to-moderate (<20 cigarettes/day) or heavy smokers (≥20 cigarettes/day). An MPA5 was used to measure SC hydration and skin melanin/erythema index on the dorsal hand, forehead, and cheek. Basal transepidermal water loss (TEWL) and barrier recovery rates were assessed on the forearm. A Skin-pH-Meter pH900 was used to measure skin surface pH. Our results showed that heavy cigarette smokers exhibited delayed barrier recovery after acute abrogation (1.02% ± 13.06 versus 16.48% ± 6.07), and barrier recovery rates correlated negatively with the number of daily cigarettes consumption (p = 0.0087). Changes in biophysical parameters in cigarette smokers varied with body sites. In conclusion, heavy cigarette smokers display compromised permeability barrier homeostasis, which could contribute, in part, to the increased prevalence of certain cutaneous disorders characterized by defective permeability. Thus, improving epidermal permeability barrier should be considered for heavy cigarette smokers. PMID:27437403

    In order to assess the potential health risks of Hg pollution, total mercury (T-Hg) and methyl mercury (MeHg) concentrations were determined in air, dust, surface soil, crops, poultry, fish and human hair samples from an electronic waste (e-waste) recycling area in Taizhou, China. High concentrations of T-Hg and MeHg were found in these multiple matrices, and the mean concentration was 30.7 ng/m(3) of T-Hg for atmosphere samples, 3.1 μg/g of T-Hg for soil, 37.6 μg/g of T-Hg for dust, 20.3 ng/g of MeHg for rice and 178.1 ng/g of MeHg for fish, suggesting that the e-waste recycling facility was a significant source of Hg. The inorganic Hg (I-Hg) levels (0.84 μg/g) in hair samples of e-waste workers were much higher than that in the reference samples. Pearson's correlation coefficients showed that strong positive correlations (p<0.01) between hair I-Hg and time staying in industrial area (r=0.81) and between MeHg and fish consumption frequency (r=0.91), imply that workers were mainly exposed to Hg vapor through long-time inhalation of contaminated air and dust, while other population mainly exposed to MeHg through high-frequency fish consumption. The estimated daily intakes of Hg showed that dietary intake was the major Hg exposure source, and Hg intakes from rice and fish were significantly higher than from any other foods. The estimated total daily intakes (TDIs) of MeHg for both children (696.8 ng/(kg·day)) and adults (381.3 ng/(kg·day)) greatly exceeded the dietary reference dose (RfD) of 230 ng/(kg·day), implying greater health risk for humans from Hg exposures around e-waste recycling facilities.

    A large subset of individuals who smoke cigarettes do not smoke regularly, but the assessments used to collect data on cigarette consumption in nondaily smokers have not been rigorously evaluated. The current study examined several self-report and biomarker approaches to the assessment of cigarette use in a sample of nondaily smokers (n = 176). Participants were randomly assigned to a daily monitoring condition (n = 89), requiring a daily report of the number of cigarettes smoked in the previous 24 hours, or a no monitoring condition (n = 87). Number of cigarettes smoked over the first 28 days of the study was assessed using 2 quantity frequency measures, a graduated frequency measure, and a timeline follow back (TLFB) interview at the Session 5 study visit. Hair nicotine (NIC), hair cotinine (COT), and expired-air carbon monoxide (CO) were collected from each participant. Total cigarettes reported via daily report were strongly correlated with all Session 5 measures of total cigarettes, but were most strongly associated with TLFB total cigarettes. Collapsed CO across 5 sessions was the biomarker most strongly correlated with daily report total cigarettes. The results support the use of daily report and TLFB methods of assessing cigarette use in nondaily smokers. Results also support the use of CO as appropriate biological markers of exposure in nondaily smokers, and point to some limitations in the use of hair biomarkers in this population.

    Background The magnitude of the negative energy balance induced by exercise may be reduced due to compensatory increases in energy intake. Objective To address the question: Does increased exercise or physical activity alter ad-libitum daily energy intake or macronutrient composition in healthy adults? Data Sources PubMed and Embase were searched (January 1990–January 2013) for studies that presented data on energy and/or macronutrient intake by level of exercise, physical activity or change in response to exercise. Ninety-nine articles (103 studies) were included. Study Eligibility Criteria Primary source articles published in English in peer-reviewed journals. Articles that presented data on energy and/or macronutrient intake by level of exercise or physical activity or changes in energy or macronutrient intake in response to acute exercise or exercise training in healthy (non-athlete) adults (mean age 18–64 years). Study Appraisal and Synthesis Methods Articles were grouped by study design: cross-sectional, acute/short term, non-randomized, and randomized trials. Considerable heterogeneity existed within study groups for several important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and presented by study design. Results No effect of physical activity, exercise or exercise training on energy intake was shown in 59% of cross-sectional studies (n = 17), 69% of acute (n = 40), 50% of short-term (n = 10), 92% of non-randomized (n = 12) and 75% of randomized trials (n = 24). Ninety-four percent of acute, 57% of short-term, 100% of non-randomized and 74% of randomized trials found no effect of exercise on macronutrient intake. Forty-six percent of cross-sectional trials found lower fat intake with increased physical activity. Limitations The literature is limited by the lack of adequately powered trials of sufficient duration, which have prescribed and measured exercise energy expenditure

    Frailty has been recognized as a risk factor for geriatric adverse events. Little is known of the role of psychosocial factors associated with frailty in explaining negative outcomes of aging. This study was aimed at 1) evaluating the differences in psychosocial factors among robust, prefrail, and frail individuals and 2) investigating whether there was any interaction effect of frailty status with empirically identified clusters of psychosocial factors on autonomy in the activities of daily living (ADLs). Two-hundred and ten older adults (age 73±6 years, 66% women) were involved in this study. Frailty was assessed using an adapted version of the frailty phenotype. The psychosocial factors investigated were depressive symptoms using the 20-item Center for Epidemiologic Studies Depression Scale, social isolation using the Friendship Scale, and loneliness feeling using the eight-item UCLA Loneliness Scale. The autonomy in ADLs was measured with the Groningen Activity Restriction Scale. Thirty-one percent of participants were robust, 55% prefrail, and 14% frail. We performed an analysis of covariance which showed differences between robust, prefrail, and frail individuals for all the psychosocial variables: Center for Epidemiologic Studies Depression Scale, F(2, 205)=18.48, P<0.001; Friendship Scale, F(2, 205)=4.59, P=0.011; UCLA Loneliness Scale, F(2, 205)=5.87, P=0.003, controlling for age and sex. Using the same covariates, the two-way analysis of covariance indicated an interaction effect of frailty with psychosocial factors in determining ADLs, F(4, 199)=3.53, P=0.008. This study demonstrates the close relationship between frailty and psychosocial factors, suggesting the need to take into account simultaneously physical and psychosocial components of human functioning.

    2012-01-01

    Background Tobacco smoking is an important public health concern worldwide leading to both chronic disease and early death. In Latin America, smoking prevalence is estimated at approximately 30% and prior studies suggest that the prevalence in Peru is 22% to 38%. We sought to determine the prevalence of daily smoking in a poor peri-urban community in Lima, Peru. Methods We conducted a cross-sectional survey in a random sample of adults ≥40 years of age living in Pampas de San Juan de Miraflores, Lima, Peru. We asked participants to respond to a survey that included questions on sociodemographics, tobacco use and dependence. Results We enrolled 316 participants. Average monthly household income was ≤ 400 USD and nearly all homes had running water, sewage, and electricity. Most individuals had not completed high school. Smoking prevalence was 16% overall, yet daily smoking prevalence was 1.9%. Former daily smokers comprised 3.8% of current nonsmokers and 9.1% current occasional smokers. Average scores for the Fagerstrom Test for Nicotine Dependence for daily smokers and occasional smokers were 1.5 and 0, respectively. Conclusions Daily use of tobacco is uncommon among adults in peri-urban communities of Lima, Peru, unlike their counterparts in Lima and other Latin American capital cities. Tobacco dependence is also low. Hence, efforts aimed at primary prevention are of utmost importance in these communities. This study provides an accurate baseline using an internationally recognized assessment tool (Global Adult Tobacco Survey), allowing for accurate assessment of tobacco control interventions over time.

    Background Smoking is one of the major modifiable risk factors for non-communicable diseases. Our aim was to report the pattern of active and passive smoking using the data collected through a population-base household survey in Kerman, Iran [(KERCADRS) Kerman Coronary Artery Disease Risk Factors Study]. Methods Using a cluster random sampling design, we recruited 5900 adult persons (15-75 years old) into our survey. After consenting, every participant was interviewed by a trained interviewer. The section for smoking included questions about daily (smoking at least one cigarette per day), non-daily, past and passive cigarette smoking as well as the duration of the exposure. We used Kerman population distribution (as the target population) to adjust our estimates using direct standardization method. Findings Overall, 8.3% of study participants (15.5% in men vs. 0.8% in women, P = 0.010) reported themselves as daily smokers and an additional 1.7% (2.9% in men vs. 0.4% in women, P = 0.010) as non-daily smokers. The passive smoking was common in total (27.5%), while women experienced more exposure than men (30.1% vs. 25.0%, P = 0.010). In daily smokers, 3.2% smoked more than 20 cigarettes per day. Among passive smokers, 62.6% were exposed to cigarette smoke more than 6 days per week. Conclusion Smoking is pretty common among adult populations, particularly in men. A majority of tobacco-free young adult women are exposed to passive smoking. Age and gender oriented interventions are required to change this risk pattern in Kerman community to prevent from further smoking related morbidities and mortalities. PMID:27274789

    Adults with depression evidence higher rates of smoking and lower quit rates than adults without depression. Little is known about the relationship between depression and smoking beliefs which are associated with both smoking and smoking cessation behavior. The primary aim of this study was to examine whether adult smokers with and without a history of major depressive disorder (MDD) differ in their endorsement of smoking expectancies. The secondary aim of the study was to examine whether there were interactions of depression and gender on the endorsement of expectancies. Adult cigarette smokers participating in a clinical trial of Selegiline hydrochloride for smoking cessation were classified as having a history of depression (MDD+, n=26) or no history of depression (MDD-, n=75). History of depression and smoking expectancies were assessed prior to randomization into the clinical trial. There was a main effect of depression on 7 out of 10 of the assessed beliefs. MDD+ smokers, compared to MDD- smokers, more strongly endorsed beliefs that smoking reduces negative affect, boredom, and cravings; smoking increases stimulation and social facilitation; smoking helps to manage cravings and weight; and that the taste is enjoyable. The main effect of gender and the interactive effect of depression and gender were not significant. Incorporating expectancies into cognitive-behavioral treatments for smoking cessation may be useful for smokers with a history of depression.

    Many who smoke in college do so infrequently and smoking conditions are not well-understood. We examined smoking patterns among college fraternity and sorority members (N=207) from a Midwestern university in three successive fall semesters in 2006–2008. Participants completed calendar-assisted retrospective assessments of 30-day smoking at up to 5 assessment points over 96 days. Overall smoking rates declined over the course of each semester and higher smoking on weekends was observed, with more variability among daily smokers. The most frequent categories of events to cue recall of smoking were socializing, work, and school. Findings can be used to target prevention efforts. PMID:21210723

    Background Individuals in recovery from alcohol use disorders (AUDs) frequently continue to smoke cigarettes. The purpose of this study was to examine the relationship between cigarette smoking status and risk of AUD relapse in adults with remitted AUDs among adults in the United States. Methods Data were drawn from Wave 1 (2001–2002) and Wave 2 (2004–2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses included the subsample of respondents who completed both waves of data collection reported a history of alcohol abuse and/or dependence prior to Wave 1 (N=9,134). Relationships between Wave 1 cigarette smoking status (non-smoker, daily cigarette smoker, non-daily cigarette smoker) and Wave 2 alcohol use, abuse, and dependence were examined using logistic regression analyses. Analyses were adjusted for Wave 1 demographics; mood, anxiety, and substance use disorders; nicotine dependence; and AUD severity. Results Both daily and non-daily cigarette smoking at Wave 1 were significantly associated with a lower likelihood of alcohol use and a greater likelihood of alcohol abuse and dependence at Wave 2 compared to Wave 1 non-smoking. These relationships remained significant after adjusting for demographics, psychiatric disorders, substance use disorders, AUD severity, and nicotine dependence. Conclusions Among adults with remitted AUDs, daily and non-daily use of cigarettes was associated with significantly decreased likelihood of alcohol use and increased likelihood of alcohol abuse and alcohol dependence three years later. Concurrent treatment of cigarette smoking when treating AUDs may help improve long-term alcohol outcomes and reduce the negative consequences of both substances. PMID:26365044

  14. Smoker Identity and Its Potential Role in Young Adults’ Smoking Behavior: A Meta-Ethnography

    PubMed Central

    2015-01-01

    Objective: Identity is an important influence on behavior. To identify potential targets for smoking cessation interventions in young adults, we synthesized findings from qualitative studies on smoker identity and potential influences on smoking and smoking cessation. Methods: A systematic search of 4 electronic databases up to September 19, 2013, was conducted to identify qualitative studies on smoker identity in smokers and ex-smokers aged 16–34. Key concepts were extracted from individual studies and synthesized into higher-order interpretations by following the principles of meta-ethnography. Results: Seventeen relevant papers were identified. At the highest level of interpretation, we identified 4 types of findings: (a) contributory factors to identity, (b) identity in relation to smoking, (c) contextual and temporal patterning, and (d) behavior in relation to smoking. Contributory factors included the desire to establish aspirational individual and social identities, enact a smoker identity appropriate to the momentary social context, and alter personal nonsmoking rules when consuming alcohol. Smoker identity was multifaceted and incorporated individuals’ defensive rationalizations, and both positive and negative feelings attached to it. Smoker identities took time to develop, were subject to change, and were context dependent. Identity was found to play a role in quit attempts. Conclusions: Qualitative research into the identity of young adult smokers has established it as a multifaceted phenomenon serving important functions but also involving conflict and defensive rationalizations. It develops over time and contextual factors influence its expression. The nature of a smoker’s identity can play an important role in smoking cessation. PMID:25622078

    2014-01-01

    Introduction: We examined homes of hookah-only smokers and nonsmokers for levels of indoor air nicotine (a marker of secondhand smoke) and indoor surface nicotine (a marker of thirdhand smoke), child uptake of nicotine, the carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), and the toxicant acrolein by analyzing their corresponding metabolites cotinine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and NNAL-glucuronides (total NNAL) and 3-hydroxypropylmercapturic acid. Methods: Data were collected at 3 home visits during a 7-day study period from a convenience sample of 24 households with a child 5 years or younger. Three child urine samples and 2 air and surface samples from the living room and the child bedroom were taken in homes of nonsmokers (n = 5) and hookah-only smokers (n = 19) comprised of daily hookah smokers (n = 8) and weekly/monthly hookah smokers (n = 11). Results: Nicotine levels in indoor air and on surfaces in the child bedrooms in homes of daily hookah smokers were significantly higher than in homes of nonsmokers. Uptake of nicotine, NNK, and acrolein in children living in daily hookah smoker homes was significantly higher than in children living in nonsmoker homes. Uptake of nicotine and NNK in children living in weekly/monthly hookah smoker homes was significantly higher than in children living in nonsmoker homes. Conclusions: Our data provide the first evidence for uptake of nicotine, the tobacco-specific lung carcinogen NNK, and the ciliatoxic and cardiotoxic agent acrolein in children living in homes of hookah smokers. Our findings suggest that daily and occasional hookah use in homes present a serious, emerging threat to children’s long-term health. PMID:24590387

  16. Food venue choice, consumer food environment, but not food venue availability within daily travel patterns are associated with dietary intake among adults, Lexington Kentucky 2011

    2013-01-01

    Objective The retail food environment may be one important determinant of dietary intake. However, limited research focuses on individuals’ food shopping behavior and activity within the retail food environment. This study’s aims were to determine the association between six various dietary indicators and 1) food venue availability; 2) food venue choice and frequency; and 3) availability of healthy food within food venue. Methods In Fall, 2011, a cross-sectional survey was conducted among adults (n=121) age 18 years and over in Lexington, Kentucky. Participants wore a global position system (GPS) data logger for 3-days (2 weekdays and 1 weekend day) to track their daily activity space, which was used to assess food activity space. They completed a survey to assess demographics, food shopping behaviors, and dietary outcomes. Food store audits were conducted using the Nutrition Environment Measurement Survey-Store Rudd (NEMS-S) in stores where respondents reported purchasing food (n=22). Multivariate logistic regression was used to examine associations between six dietary variables with food venue availability within activity space; food venue choice; frequency of shopping; and availability of food within food venue.

    A recent trend in human motion capture is the use of inertial measurement units (IMUs) for monitoring and performance evaluation of mobility in the natural living environment. Although the use of such systems have grown significantly, the development of methods and algorithms to process IMU data for clinical purposes is still limited. The aim of this work is to develop algorithms based on wavelet transform and discrete-time detection of events for the automatic segmentation of tasks related activities of daily living (ADL) from body worn IMUs. Seven healthy older adults (73  ±  4 years old) performed 10 ADL tasks in a simulated apartment during trials of different durations (3, 4, and 5 min). They wore a suit (Synertial UK Ltd IGS-180) comprised of 17 IMUs positioned strategically on body segments to capture full body motion. The proposed method automatically detected the number of template waveforms (representing each movement separately) using discrete wavelet transform (DWT) and discrete-time detection of events based on angular velocity, linear acceleration and 3D orientation data of pertinent IMUs. The sensitivity (Se.) and specificity (Sp.) of detection for the proposed method was established using time stamps of10tasks obtained from visual segmentation of each trial using the video records and the avatar provided by the system's software. At first, we identified six pertinent sensors that were strongly associated to different activities (at most two sensors/task) that allowed detection of tasks with high accuracy. The proposed algorithm exhibited significant global accuracy (N events  =  1999, Se.  =  97.5%, Sp.  =  94%), despite the variation in the occurrences of the performed tasks (free living). The Se. varied from 94% to 100% for all the detected ADL tasks and Sp. ranged from 90% to 100% with the worst Sp.  =  85 and 87% for Release_mid (reaching for object held just beyond reach at chest height) and Turning

    The majority of smokers have no plans to quit in the near future. These complacent smokers are less likely to quit than other smokers, and few interventions are known to reduce smoking in this population. Although monetary incentives can reduce complacent smokers' breath carbon monoxide (BCO) levels, it is not clear whether these effects can be sustained beyond the several weeks that past studies have examined. The authors compared complacent smokers randomly assigned to receive incentives for BCO reductions (n=18) or noncontingent incentives (n=19) for 3 months. Contingent incentives were associated with (a) reduced BCO; (b) more BCO samples indicative of abstinence; (c) fewer cigarettes smoked and more days abstinent at study end; and (d) lower salivary cotinine. These behaviors can predict future cessation, and 2 of the 18 smokers (11%) receiving BCO-contingent incentives reported quitting as compared with none in the control group. Contingency management procedures, such as those used here, may effectively promote cessation among complacent smokers and provide a model for understanding the possible effects of some environmental interventions (like workplace smoking bans) on the behavior of complacent smokers.

    The uniformity of regional ventilation during tidal breathing has been assessed using continuous inhalation of krypton-81m in 43 male, lifelong nonsmokers and 46 male, current cigarette smokers (mean daily consumption 24.1 cigarettes/day) between 44 and 61 yr of age and with mild or no respiratory symptoms. All subjects had normal chest radiographs. The results of the ventilation scans were compared with tests of overall lung function (spirometry, maximal expiratory flow-volume curves, and single-breath N2 test). Diffuse abnormalities of the ventilation scan were found in 19 (41%) of the 46 smokers but in none of the nonsmokers. Focal abnormalities were found in 7 smokers and 3 nonsmokers. Smokers showed the expected abnormalities in overall lung function (reduced FEV1 and VC, increased single-breath N2 slope, and closing volume), but in individual smokers there was only a weak relation between the severity of abnormality of overall lung function and an abnormal ventilation scan. Abnormal scans could be found when overall lung function was normal and were not invariably found when significant abnormalities in FEV1/VC or N2 slope were present. There was no relation between the presence of chronic expectoration and an abnormal scan. The prognostic significance of an abnormal ventilation scan in such smokers remains to be established.

    Introduction: Although the evidence is mixed, female smokers appear to have more difficulty quitting smoking than male smokers. Craving, stress, and negative affect have been hypothesized as potential factors underlying gender differences in quit rates. Methods: In the current study, the cue-reactivity paradigm was used to assess craving, stress, and negative affect in response to cues presented in the natural environment of cigarette smokers using ecological momentary assessment. Seventy-six daily smokers (42% female) responded to photographs (smoking, stress, and neutral) presented 4 times per day on an iPhone over the course of 2 weeks. Results: Both smoking and stress cues elicited stronger cigarette craving and stress responses compared to neutral cues. Compared with males, females reported higher levels of post-stress cue craving, stress, and negative affect, but response to smoking cues did not differ by gender. Discussion: Findings from this project were largely consistent with results from laboratory-based research and extend previous work by measuring response to cues in the natural environment of cigarette smokers. This study extends previous cue reactivity ecological momentary assessment research by using a new platform and by measuring response to stress cues outside of the laboratory. Findings from this project highlight the importance of addressing coping in response to stress cues in clinical settings, especially when working with female smokers. PMID:25762753

    The association between psychopathology and nicotine dependence in smokers has been a relevant topic in recent years. Nevertheless, little is known about personality disorders in smokers. The aim of this article is to review research published nationally and internationally which analyzes the relation between tobacco use and personality disorders. Our review permits us to affirm that research on the presence of Axis II disorders in smokers is rather scarce. Of 12 studies analyzed, it can be concluded that the prevalence of personality disorders in smokers is highly variable (between 9% and 45%), and that, in the majority of the studies, smoking is associated first with the presence of cluster C disorders (dependent, avoidant and obsessive-compulsive), and second, with cluster B disorders (histrionic, narcissistic, borderline and antisocial). Finally, we note the various limitations of previous studies and stress the need to better understand these disorders, given their relevance to the treatment of smokers.

    The structures and evolution of Smoker in a 20 kHz ultrasonic field were investigated experimentally with high-speed photography. The spine-plume structure of Smoker was discovered. A few large bubbles align themselves along the central line and form the spine of Smoker. Numerous small bubbles move towards the spine and form the plume structures. The size of large bubbles differs almost by an order of magnitude from that of small bubbles. The evolution of cavitation structure from Flare to Smoker was found. When a Flare appears near a Smoker, the Flare may merge into the plume structures of the Smoker, or form a double-tipped Smoker. A double-tipped Smoker seldom splits into two Smokers, while two separate Smokers tend to merge as one. The large bubbles (or dense plume structures) in the middle part of the two separate Smokers attract each other, driving the two Smokers to bend towards each other and merge.

    Lung cancer in never smokers (LCINS) has lately been recognized as a unique disease based on rapidly gained knowledge from genomic changes to treatment responses. The focus of this article is on current knowledge and challenges with regard to LCINS expanded from recent reviews highlighting five areas: (1) distribution of LCINS by temporal trends, geographic regions, and populations; (2) three well-recognized environmental risk factors; (3) other plausible environmental risk factors; (4) prior chronic lung diseases and infectious diseases as risk factors; and (5) lifestyles as risk or protective factors. This article will also bring attention to recently published literature in two pioneering areas: (1) histological characteristics, clinical features with emerging new effective therapies, and social and psychological stigma; and (2) searching for susceptibility genes using integrated genomic approaches.

    Introduction: Smokers who report quitting without prior planning have been shown to report longer abstinence compared with those who planned. Little is known about unplanned quitting (UQ) among U.S. smokers, minorities, or nondaily and light smokers. Methods: Using an online panel, we recruited equal numbers of Black, White, and Latino nondaily, light daily, and moderate/heavy daily smokers. Of the 1,127 who reported a past-year quit attempt, we queried whether it was planned and the maximum number of days abstinent. Results: Overall, 38% reported that their last quit attempt was unplanned. The impact of planned versus unplanned quitting interacted with smoking level and race. Among White moderate/heavy smokers, mean days abstinent was 99 for those who reported an unplanned quit attempt compared with 60 days for those who reported a planned attempt (p = .02). Among Black moderate/heavy smokers, the mean days abstinent was higher among those whose last attempt was planned, 92 days, compared with 56 days among those whose last attempt was unplanned (p = .09). The pattern among Latinos resembled Whites but was not significant. Results remained after adjusting for confounds such as age, gender, education, income, time to first cigarette, and menthol use. There were no significant differences in abstinence by quit type for light or nondaily smokers. Conclusions: Future studies are needed to elucidate why UQ appears to have differential effectiveness across racial/ethnic groups and different levels of cigarette use. Research examining the impact of UQ on long-term quitting, which is not addressed here, is needed. PMID:24420329

    Previous studies have shown an equivalent pharmacokinetic profile between four-times-daily (4QD) and once-daily (QD) administration of intra-venous (IV) BU, without increased toxicity. We assess the impact of a switch in IV BU from a 4QD to a QD schedule, in terms of health-care organization, staff working conditions, quality of care dispensed and perceived patient comfort. Clinicians, nurses and pharmacists from nine allogeneic transplantation units in five European countries were interviewed face to face. Overall perception of QD versus 4QD BU was very positive. Both administration schemes were evaluated to be equally efficaciousZ. QD BU was perceived to be safer and more convenient. Clinicians and nurses perceived that patient comfort was improved, due to fewer complications associated with repeated infusions, and avoiding night infusions associated with stress, anxiety and decreased quality of sleep. Switching from 4QD to QD BU had a significant impact on health-care organization, with a better integration in the overall management and usual timelines in the pharmacies and transplantation units. Time spent to prepare and administer BU was significantly reduced, leading to potential financial savings that merit further assessment and would be of particular interest in the current economic climate.

    Introduction: College smokers are often considered to be one homogenous group, those reporting smoking on at least one of the past 30 days. However, considerable heterogeneity exists among college students who report current smoking. The aim of this paper is to characterize disparate patterns of smoking among college students using latent class analysis (LCA). Methods: The sample consisted of 1,102 past-month smokers from 10 colleges in North Carolina who completed a Web-based survey. LCA was used to create homogeneous groups of smokers with similar patterns defined by multiple indicators of smoking behavior, including quantity and frequency of smoking, smoking contexts, and weekly patterns of smoking. Results: Five subclasses of smokers were identified: “heavy smokers” (28%), moderate smokers (22%), social smokers (19%), puffers (26%), and no-context smokers (4%). Demographic characteristics that varied among these subgroups were year in school, Greek membership, and residence location. Puffers were more likely to be younger students than heavy and social smokers, suggesting a transition from experimentation to regular use over time. Social smokers and puffers were more likely to be involved in Greek organizations than were heavy and moderate smokers. Moderate and social smokers were more likely to be current drinkers and to have engaged in binge drinking in the past month than were heavy smokers. This finding suggests that, for moderate and social smokers, a strong relationship exists between alcohol and tobacco use. Discussion: The results highlight the heterogeneity of college student smokers and underscore the need for targeted interventions. PMID:19264866

    In this study, effect of long term smoking on sensitivity of cough reflex was investigated. Healthy, current smoker male and female was evaluated by capsaicin cough challenge test and they were compared with healthy, non-smoker persons with similar age and gender, prospectively. In current smokers, there were 50 male and 39 female, in non-smoker control group, there were 20 male and 21 female. Mean and log C5 dosage in current smoker and non-smoker groups and mean and log C5 dosage in current smoker according to gender were calculated by using Mann-Whitney U-test. Results of capsaicin cough challenge test in current and non-smoker groups were evaluated by using Pearson Chi-Square test and Fisher's Exact test. In current smokers comparison of results of capsaicin cough challenge test with smoking history (age with first smoking, duration, pocket year and smoking per day) was evaluated by using Mann-Whitney U-test. Mean C5 and mean log C5 dosage were found decreased in current smokers when they were compared to control group (p< 0.00). In current smoker group mean C5 and mean log C5 dosage were found decreased in male (p< 0.002). When the results of capsaicin cough challenge test were compared between current smoker and control groups, sensitivity of cough reflex in concentration with 0.49, 0.98, 1.95, 3.9, 7.8, 15.6 microM was significantly decreased in current smoker group. Also there was a significant correlation between concentration with 0.98, 1.95, 3.9, 7.8, 15.6, 31.2 microM, and duration of smoking and pocket year of smoking. Also there was a correlation between concentration with 15.6, 31.2, 62.5, 125 microM and smoking per day. This results were correlated with hypothesis about inhibition of C-fibers with nicotin or decrease of C-fibers' sensitivity due to induction of neuropeptide wasting. PMID:18330750

    Background We have recently published some work on CEA levels in hookah (also called narghile, shisha elsewhere) and cigarette smokers. Hookah smokers had higher levels of CEA than non-smokers although mean levels were low compared to cigarette smokers. However some of them were also users of other tobacco products (cigarettes, bidis, etc.). Objectives To find serum CEA levels in ever/exclusive hookah smokers, i.e. those who smoked only hookah (no cigarettes, bidis, etc.), prepared between 1 and 4 times a day with a quantity of up to 120 g of a tobacco-molasses mixture each (i.e. the tobacco weight equivalent of up to 60 cigarettes of 1 g each) and consumed in 1 to 8 sessions. Methods Enhanced chemiluminescent immunometric technique was applied to measure CEA levels in serum samples from 59 exclusive male smokers with age ranging from 20–80 years (mean = 58.8 ± 14.7 years) and 8–65 years of smoking (mean = 37.7 ± 16.8). 36 non-smokers served as controls. Subjects were divided into 3 groups according to the number of preparations; the number of sessions and the total daily smoking time: Light (1; 1; ≤ 20 minutes); Medium (1–3; 1–3; >20 min to ≤ 2 hrs) and Heavy smokers (2–4; 3–8; >2 hrs to ≤ 6 hrs). Because of the nature of distribution of CEA levels among our individuals, Wilcoxon's rank sum two-sample test was applied to compare the variables. Results The overall CEA levels in exclusive hookah smokers (mean: 3.58 ± 2.61 ng/ml; n = 59) were not significantly different (p ≤ 0.0937) from the levels in non-smokers (2.35 ± 0.71 ng/ml). Mean levels in light, medium and heavy smokers were: 1.06 ± 0.492 ng/ml (n = 5); 2.52 ± 1.15 ng/ml (n = 28) and 5.11 ± 3.08 ng/ml (n = 26) respectively. The levels in medium smokers and non-smokers were also not significantly different (p ≤ 0.9138). In heavy smokers, the CEA levels were significantly higher than in non-smokers (p ≤ 0.0001567). Conclusion Overall CEA levels in exclusive hookah smokers were

    Aims To evaluate state cigarette excise tax pass-through rates for selected price-minimizing strategies. Design Multivariate regression analysis of current smokers from a stratified, national, dual-frame telephone survey. Setting United States. Participants A total of 16 542 adult current smokers aged 18 years or older. Measurements Cigarette per pack prices paid with and without coupons were obtained for pack versus carton purchase, use of generic brands versus premium brands, and purchase from Indian reservations versus outside Indian reservations. Findings The average per pack prices paid differed substantially by price-minimizing strategy. Smokers who used any type of price-minimizing strategies paid substantially less than those who did not use these strategies (P < 0.05). Premium brand users who purchased by pack in places outside Indian reservations paid the entire amount of the excise tax, together with an additional premium of 7–10 cents per pack for every $1 increase in excise tax (pass-through rate of 1.07–1.10, P < 0.05). In contrast, carton purchasers, generic brand users or those who were likely to make their purchases on Indian reservations paid only 30–83 cents per pack for every $1 tax increase (pass-through rate of 0.30–0.83, P < 0.05). Conclusions Many smokers in the United States are able to avoid the full impact of state excise tax on cost of smoking by buying cartons, using generic brands and buying from Indian reservations.

    Background Smoking is the cause of inducing changes in taste functionality under conditions of chronic exposure. The objective of this study was to evaluate taste sensitivity in young smokers and non-smokers and identify any differences in the shape, density and vascularisation of the fungiform papillae (fPap) of their tongue. Methods Sixty-two male subjects who served in the Greek military forces were randomly chosen for this study. Thirty-four were non-smokers and 28 smokers. Smokers were chosen on the basis of their habit to hold the cigarette at the centre of their lips. Taste thresholds were measured with Electrogustometry (EGM). The morphology and density of the fungiform papillae (fPap) at the tip of the tongue were examined with Contact Endoscopy (CE). Results There was found statistically important difference (p < 0.05) between the taste thresholds of the two groups although not all smokers presented with elevated taste thresholds: Six of them (21%) had taste thresholds similar to those of non-smokers. Differences concerning the shape and the vessels of the fungiform papillae between the groups were also detected. Fewer and flatter fPap were found in 22 smokers (79%). Conclusion The majority of smokers shown elevated taste thresholds in comparison to non-smokers. Smoking is an important factor which can lead to decreased taste sensitivity. The combination of methods, such as EGM and CE, can provide useful information about the vascularisation of taste buds and their functional ability. PMID:19695082

    Aim: To investigate a potential difference in ocular vascular reactivity during carbogen breathing in optic nerve head, choroid, and retina between healthy smokers and non-smokers. Methods: 25 (13 smokers and 12 non-smokers) healthy male volunteers participated in this observer masked, two cohort study. During inhalation of carbogen (5% CO2 and 95% O2) over 10 minutes measurements were taken using laser Doppler flowmetry to assess submacular choroidal and optic nerve head blood flow, laser interferometry to assess fundus pulsation amplitudes, and retinal vessel analyser (RVA) to assess retinal vessel diameters. Results: At baseline choroidal blood flow was higher (p = 0.018, ANOVA) in smokers than in non-smokers. During administration of carbogen the response in choroidal blood flow was significantly different between the two groups: there was an increase in non-smokers after carbogen breathing (p = 0.048) compared with relatively stable blood flow in smokers (p = 0.049 between groups, ANOVA). A similar response pattern was seen for fundus pulsation amplitude, which increased notably after carbogen breathing in non-smokers but not in smokers (p<0.001 between groups, ANOVA). Optic nerve head blood flow and retinal vessel diameters were reduced in both groups to a comparable degree during carbogen breathing. Conclusion: The study indicated abnormal choroidal vascular reactivity in chronic smokers. These early haemodynamic changes may be related to the increased risk to smokers of developing ocular vascular diseases. The specific mechanisms underlying abnormal choroidal vascular reactivity in chronic smokers remain to be characterised. PMID:15148211

    Objectives. We identified the mass media channels that reach the most cigarette smokers in an attempt to more effectively target smoking cessation messages. Methods. Reach estimates and index scores for smokers were taken from 2002–2003 ConsumerStyles and HealthStyles national surveys of adults (N=11660) to estimate overall and demographic-specific exposure measures for television, radio, newspapers, and magazines. Results. Smokers viewed more television, listened to more radio, and read fewer magazines and newspapers than did nonsmokers. Nearly one third of smokers were regular daytime or late-night television viewers. Selected cable television networks (USA, Lifetime, and Discovery Channel) and selected radio genres, such as classic rock and country, had high reach and were cost-efficient channels for targeting smokers. Conclusions. Certain mass media channels offer efficient opportunities to target smoking cessation messages so they reach relatively large audiences of smokers at relatively low cost. The approach used in this study can be applied to other types of health risk factors to improve health communication planning and increase efficiency of program media expenditures. PMID:17600264

    This study aimed to assess sperm DNA and RNA abnormalities in fertile and oligoasthenoteratozoospermic (OAT) smokers. In all, 140 subjects were included and classified into fertile nonsmokers, fertile smokers, OAT nonsmokers and OAT smokers. They were subjected to history taking, clinical examination, semen analysis, assessment of sperm DNA and RNA abnormalities. The results showed that an increased percentage of abnormal sperm DNA and RNA was demonstrated in fertile smokers compared with fertile nonsmokers and in OAT smokers compared with OAT nonsmokers. Increased percentage of severe, moderate sperm DNA and RNA damage was demonstrated in fertile heavy smokers compared with fertile light smokers and in OAT heavy smokers compared with OAT light smokers. It is concluded that smoking has a negative impact on sperm DNA and RNA abnormalities that is accentuated in heavy smokers compared with light smokers.

  15. Use of cessation methods among smokers aged 16-24 years--United States, 2003.

    2006-12-22

    Smoking cessation among adolescent smokers is relatively rare, with approximately 15.6% of smokers aged 12-19 years quitting smoking in a 4-year period (approximately 4% per year). Rates for failed quitting attempts among younger smokers are higher than those for adults (43%), with approximately 58% of high-school smokers having tried to quit at least once for 1 day or longer in the preceding year. To track the history of quitting behavior among smokers aged 16-24 years, Roswell Park Cancer Institute (Buffalo, New York) initiated the 2-year longitudinal National Youth Smoking Cessation Survey (NYSCS) in 2003. This report summarizes key findings from the survey regarding lifetime use of smoking-cessation methods. The findings indicated that smokers aged 16-24 years who had tried to quit were more likely to use unassisted quitting methods than assisted quitting methods; none of the unassisted methods are recommended by the Public Health Service (PHS) clinical guidelines for treatment of tobacco use and dependence, whereas most of the assisted methods are recommended for adults and have been determined to be effective. Many youths aged 16-24 years are trying to quit smoking but often underestimate the rapid progression to tobacco dependence; therefore, PHS clinical practice guidelines for treating tobacco use and dependence recommend that certain clinical interventions proven to be effective among adults be used in youth-based approaches to cessation. In addition, other components of comprehensive tobacco-control programs also increase smoking cessation and should be implemented at CDC-recommended levels to lower tobacco use among youths and adults.

    The Avoidance and Inflexibility Scale (AIS; Gifford et al., 2004) was derived as smoking-specific measure of experiential avoidance. However, there has been little investigation of the psychometric proprieties of the AIS and no published work on the topic. The current study aimed to test the reliability and validity of the AIS among a sample of adult treatment-seeking daily smokers (n = 465; 48.1% female, 17.8 [SD = 9.60] cigarettes per day). The AIS was administered at three time points (Baseline, Quit day, 1 month post-quit) as part of a larger smoking cessation trial. An exploratory factor analysis indicated a two-factor solution, described by inflexibility and avoidance due to smoking related “thoughts/feelings” (9 items) and “somatic sensations” (4 items). Results revealed that the AIS-total and factor scores demonstrated high internal consistency and test-retest reliability. The AIS total and factor scores also displayed high convergent, discriminant, and incremental predictive validity with theoretically-relevant smoking and affective variables. The present data suggest that the AIS measure appears to be a valid and reliable smoking-specific index of experiential avoidance. PMID:25642937

Participants 21 Australian adult ex-smokers (aged 28–68 years; 9 males and 12 females) who quit unassisted within the past 6 months to 2 years. 12 participants had previous experience of using assistance to quit; 9 had never previously used assistance. Setting Community, Australia. Results Along with previously identified barriers to use of cessation assistance (cost, access, lack of awareness or knowledge of assistance, including misperceptions about effectiveness or safety), our study produced new explanations of why smokers quit unassisted: (1) they prioritise lay knowledge gained directly from personal experiences and indirectly from others over professional or theoretical knowledge; (2) their evaluation of the costs and benefits of quitting unassisted versus those of using assistance favours quitting unassisted; (3) they believe quitting is their personal responsibility; and (4) they perceive quitting unassisted to be the ‘right’ or ‘better’ choice in terms of how this relates to their own self-identity or self-image. Deep-rooted personal and societal values such as independence, strength, autonomy and self-control appear to be influencing smokers’ beliefs and decisions about quitting. Conclusions The reasons for smokers’ rejection of the conventional medical model for smoking cessation are complex and go beyond modifiable or correctable problems relating to misperceptions or treatment barriers. These findings suggest that GPs could recognise and respect smokers’ reasons for rejecting assistance, validate and approve

    Background Vibration response imaging (VRI) is a new technology for lung imaging. Active smokers and non-smokers show differences in VRI findings, but no data are available for passive smokers. The aim of this study was to evaluate the use of VRI and to assess the differences in VRI findings among non-smokers, active smokers, and passive smokers. Material/Methods Healthy subjects (n=165: 63 non-smokers, 56 active smokers, and 46 passive smokers) with normal lung function were enrolled. Medical history, physical examination, lung function test, and VRI were performed for all subjects. Correlation between smoking index and VRI scores (VRIS) were performed. Results VRI images showed progressive and regressive stages representing the inspiratory and expiratory phases bilaterally in a vertical and synchronized manner in non-smokers. Vibration energy curves with low expiratory phase and plateau were present in 6.35% and 3.17%, respectively, of healthy non-smokers, 41.07% and 28.60% of smokers, and 39.13% and 30.43% of passive smokers, respectively. The massive energy peak in the non-smokers, smokers, and passive-smokers was 1.77±0.27, 1.57±0.29, and 1.66±0.33, respectively (all P<0.001). A weak but positive correlation was observed between VRIS and smoking index. Conclusions VRI can intuitively show the differences between non-smokers and smokers. VRI revealed that passive smoking can also harm the lungs. VRI could be used to visually persuade smokers to give up smoking. PMID:26212715

  19. What is behind smoker support for new smokefree areas? National survey data

    PubMed Central

    2010-01-01

    Background Some countries have started to extend indoor smokefree laws to cover cars and various outdoor settings. However, policy-modifiable factors around smoker support for these new laws are not well described. Methods The New Zealand (NZ) arm of the International Tobacco Control Policy Evaluation Survey (ITC Project) derives its sample from the NZ Health Survey (a national sample). From this sample we surveyed adult smokers (n = 1376). Results For the six settings considered, 59% of smokers supported at least three new completely smokefree areas. Only 2% favoured smoking being allowed in all the six new settings. Support among Maori, Pacific and Asian smokers relative to European smokers was elevated in multivariate analyses, but confidence intervals often included 1.0. Also in the multivariate analyses, "strong support" by smokers for new smokefree area laws was associated with greater knowledge of the second-hand smoke (SHS) hazard, and with behaviours to reduce SHS exposure towards others. Strong support was also associated with reporting having smokefree cars (aOR = 1.68, 95% CI = 1.21 - 2.34); and support for tobacco control regulatory measures by government (aOR = 1.63, 95% CI = 1.32 - 2.01). There was also stronger support by smokers with a form of financial stress (not spending on household essentials). Conclusions Smokers from a range of population groups can show majority support for new outdoor and smokefree car laws. Some of these findings are consistent with the use of public health strategies to support new smokefree laws, such as enhancing public knowledge of the second-hand smoke hazard. PMID:20718985

    Little is known about the changes produced in the nasal respiratory epithelium in individuals with an important smoking habit. The purpose of this study is to compare the nasal mucociliary function in healthy subjects, smokers and non-smokers. The nasal mucociliary transport of aspartame particles was measured in 50 healthy non-smokers and in 50 healthy smokers under similar conditions. The average time taken for the displacement of the test substance from the middle third of the inferior turbinate to the oropharynx was found to be in the smokers 13.62 min., and in the non-smokers, 10.34 min. The results were compared using student's "t" test and a significant difference (p < 0.001) was found between both groups. This result is taken as a simple clinical test that evaluates the smoking effects on the nasal mucociliary function.

    Mindfulness is defined as “paying attention in a particular way, on purpose, in the present moment, and nonjudgmentally”. Mindfulness is associated with positive affect, life satisfaction, self-esteem, lower negative affect and rumination. Conversely, evidence suggests a relationship between nicotine dependence and psychiatric disorders. This study aimed to compare the levels of Mindfulness and Subjective Well-Being (SWB) between smokers and non-smokers. Ninety seven smokers and eighty four non-smokers participated in the study (n = 181). The Five Facet Mindfulness Questionnaire (FFMQ-BR) and the Subjective Well-Being Scale (SWBS) were used. In all the factors of SWBS, the total scores in the FFMQ-BR and in the facets of Observing and Non-Reactivity, the non-smokers scored higher than the smokers. This study suggests that smokers present lower levels of Mindfulness and SWB than non-smokers. Consequently, we propose that Mindfulness-Based Interventions (MBI) may help smokers deal with treatment and abstinence by increasing their level of SWB. PMID:26270556

    Smoking is a serious public health problem, and accurate real-time assessment of risk factors associated with smoking is critical to understanding smoking relapse. Negative affect is often described as a critical risk factor related to smoking relapse, and ecological momentary assessment (EMA) methods have been widely used to study real-time relations between negative affect and smoking. However, the factor structure of momentary negative affect ratings is unknown. The current investigation examined the multilevel factor structure and internal consistency of an EMA measure of negative affect. Daily assessments were collected for 1 week prequit and 3 weeks postquit from 113 adult daily smokers receiving nicotine replacement therapy and counseling to quit smoking. Results supported a 2-factor model with correlated but distinct agitation and distress factors, rather than a single-factor model of negative affect. The agitation factor was indicated by these items: impatient, tense/anxious, restless. The distress factor was indicated by these items: sad/depressed, upset, distressed. The 2-factor model had acceptable model fit and consistent factor loadings across 3 separate cessation phases: prequit, postquit with recent smoking, and postquit without recent smoking. The 2 factors were highly correlated, showed good internal consistency, and showed strong associations with theoretically relevant smoking and affect variables. Agitation was more strongly related to urge to smoke, and distress was more strongly related to recent stress. This study provides support for a 2-factor model of an EMA measure of negative affect and highlights distinct facets that may be useful for future investigations of affect and smoking.

    Introduction: Sexual and gender minority individuals (i.e., lesbian, gay, bisexual, and transgender [LGBT]) have a higher smoking prevalence than nonminority individuals. There is limited evidence of smoking abstinence success in nontailored smoking treatments among LGBT smokers. Methods: This study is a secondary data analysis comparing the efficacy of extended, nontailored treatments among sexual and gender minority and nonminority smokers. Data from two clinical trials were combined to increase power and generalizability of the findings. Trials began with 12 weeks of counseling, nicotine replacement, and bupropion, after which participants were randomized to an extended treatment. Results: Follow-up occurred at weeks 12, 24, 52, 64, and 104. Of the sample (n = 777), 17% identified as sexual and gender minority and 83% as nonminority. The sample was 75% non-Hispanic White, with 86% completing at least some college, and 68% were employed. Sexual and gender minorities were younger and indicated a greater desire to quit smoking than nonminority smokers. No other differences emerged on demographic, smoking, or mood variables. The average Fagerström Test for Nicotine Dependence score was 4.8, and mean daily cigarettes was 19.8. The generalized estimating equations model revealed no significant differences in abstinence between sexual and gender minority smokers and nonminority smokers at all follow-up assessments. Conclusions: Sexual and gender minority smokers appear as likely to quit or abstain as nonminority smokers in extended, nontailored interventions. However, these findings may not generalize to other geographic areas, where access to treatment is limited or a higher stigma of sexual orientation exists. PMID:24727483

    According to theories of addictive behaviors, approach and attentional biases toward smoking-related cues play a crucial role in tobacco dependence. Several studies have investigated these biases by using various paradigms in different sample types. However, this heterogeneity makes it difficult to compare and evaluate the results. The present study aimed to address this problem, via (i) a structural comparison of different measures of approach-avoidance and a measure of smoking-related attentional biases, and (ii) using within one study different representative samples in the context of tobacco dependence. Three measures of approach-avoidance were employed: an Approach Avoidance Task (AAT), a Stimulus Response Compatibility Task (SRC), and a Single Target Implicit Association Test (ST-IAT). To assess attentional biases, a modified Stroop task including smoking-related words was administered. The study included four groups: n = 58 smokers, n = 57 non-smokers, n = 52 cravers, and n = 54 ex-smokers. We expected to find strong tobacco-related approach biases and attentional biases in smokers and cravers. However, the general pattern of results did not confirm these expectations. Approach responses assessed during the AAT and SRC did not differ between groups. Moreover, the Stroop did not show the expected interference effect. For the ST-IAT, cravers had stronger approach associations toward smoking-related cues, whereas non-smokers showed stronger avoidance associations. However, no such differences in approach-avoidance associations were found in smokers and ex-smokers. To conclude, these data do not provide evidence for a strong role of implicit approach and attentional biases toward smoking-related cues in tobacco dependency. PMID:26955359

    Introduction Hardcore smokers are smokers who have little to no intention to quit. Previous research suggests that there are distinct subgroups among hardcore smokers and that these subgroups vary in the perceived pros and cons of smoking and quitting. Identifying these subgroups could help to develop individualized messages for the group of hardcore smokers. In this study we therefore used the perceived pros and cons of smoking and quitting to identify profiles among hardcore smokers. Methods A sample of 510 hardcore smokers completed an online survey on the perceived pros and cons of smoking and quitting. We used these perceived pros and cons in a latent profile analysis to identify possible subgroups among hardcore smokers. To validate the profiles identified among hardcore smokers, we analysed data from a sample of 338 non-hardcore smokers in a similar way. Results We found three profiles among hardcore smokers. ‘Receptive’ hardcore smokers (36%) perceived many cons of smoking and many pros of quitting. ‘Ambivalent’ hardcore smokers (59%) were rather undecided towards quitting. ‘Resistant’ hardcore smokers (5%) saw few cons of smoking and few pros of quitting. Among non-hardcore smokers, we found similar groups of ‘receptive’ smokers (30%) and ‘ambivalent’ smokers (54%). However, a third group consisted of ‘disengaged’ smokers (16%), who saw few pros and cons of both smoking and quitting. Discussion Among hardcore smokers, we found three distinct profiles based on perceived pros and cons of smoking. This indicates that hardcore smokers are not a homogenous group. Each profile might require a different tobacco control approach. Our findings may help to develop individualized tobacco control messages for the particularly hard-to-reach group of hardcore smokers.

    To develop and evaluate the feasibility of a cue reactivity paradigm for young marijuana smokers, the authors set up a laboratory procedure involving neutral and marijuana-related imagery, video, and in vivo cues. Fifteen adolescents and young adults with cannabis use disorders completed the procedure, which included continuous measurement of skin conductance and heart rate. Participants also completed questionnaires regarding marijuana craving before, during, and after cue presentations. Higher levels of craving and skin conductance were observed during marijuana cue presentations. The procedure appears to elicit cue reactivity among adolescents and young adults with cannabis use disorders and should be further evaluated and refined with a larger sample. Implications for future studies are discussed. PMID:19071985

    While substance use is one of the most consistent predictors of poor adherence to antiretroviral therapy (ART), few studies among people living with HIV (PLH) have utilized mobile phone-based assessment of these health behaviors. PLH were recruited from primary care clinics to report ART and substance use using a smartphone application (app) for 14 consecutive days. The app's feasibility as a data collection tool was evaluated quantitatively via surveys and qualitatively via in-depth interviews to assess daily report completion, compliance, and study satisfaction. Overall, 26 participants (M = 49.5 years, 76% male) completed 95.3% of time-based daily reports. Participants reported high satisfaction with the app and expressed future interest in using smartphones to report daily behaviors. High completion rates and participant acceptability suggest that smartphones are a feasible, acceptable method for collecting substance use and ART data among PLH. Potential areas of concern such as sufficient training and assistance for those with limited smartphone experience should be considered for future app-based research studies among PLH. PMID:27610243

    Abstract We performed a cross-sectional, multicentre study in Japan to detect the differences in biomarkers of exposure and cardiovascular biomarkers between smokers and non-smokers. Several clinically relevant cardiovascular biomarkers differed significantly between smokers and non-smokers, including lipid metabolism (high-density lipoprotein cholesterol concentrations – lower in smokers), inflammation (fibrinogen and white blood cell count – both higher in smokers), oxidative stress (8-epi-prostaglandin F2α – higher in smokers) and platelet activation (11-dehydro-thromboxane B2 – higher in smokers) (p ≤ 0.0001). These results provide further evidence showing that cardiovascular biomarkers can discriminate smokers from non-smokers, and could be used to evaluate the risks associated with tobacco products.

    OBJECTIVE—To test the hypothesis that proposed amendments to the Occupational Safety and Health Act making all enclosed workplaces in Western Australia smoke free would result in a decrease in cigarette consumption by patrons at nightclubs, pubs, and restaurants without adversely affecting attendance.
DESIGN—Cross sectional structured interview survey.
PARTICIPANTS AND SETTING—Patrons of several inner city pubs and nightclubs in Perth were interviewed while queuing for admission to these venues.
OUTCOME MEASURES—Current social habits, smoking habits, and how these might be affected by the proposed regulations. Persons who did not smoke daily were classified as "social smokers."
RESULTS—Half (50%) of the 374 patrons interviewed were male, 51% currently did not smoke at all, 34.3% smoked every day, and the remaining 15.7% smoked, but not every day. A clear majority (62.5%) of all 374 respondents anticipated no change to the frequency of their patronage of hospitality venues if smoke-free policies became mandatory. One in five (19.3%) indicated that they would go out more often, and 18.2% said they would go out less often. Half (52%) of daily smokers anticipated no change to their cigarette consumption, while 44.5% of daily smokers anticipated a reduction in consumption. A majority of social smokers (54%) predicted a reduction in their cigarette consumption, with 42% of these anticipating quitting.
CONCLUSIONS—One in nine (11.5%) of smokers say that adoption of smoke-free policies would prompt them to quit smoking entirely without a significant decrease in attendance at pubs and nightclubs. There can be few other initiatives as simple, cheap, and popular that would achieve so much for public health.

    Nicotine concentrations were measured in saliva and urine samples collected from 82 smokers and 56 non-smokers after a morning at work. Each subject answered a series of questions related to their recent intentional or passive exposure to tobacco smoke. All non-smokers had measurable amounts of nicotine in both saliva and urine. Those non-smokers who reported recent exposure to tobacco smoke had significantly higher nicotine concentrations (p less than 0.001) than those who had not been exposed; their concentrations overlapped those of smokers who had smoked up to three cigarettes before sampling had the greatest influence on nicotine concentrations (r=0.62 for saliva and r=0.51 for urine). Neither the nicotine for yield of cigarettes nor the self-reported degree of inhalation had any significant effect on nicotine concentrations. PMID:6802384

    This study compares the nicotine patch to placebo in young adult light smokers, and the nicotine patch to varenicline in heavy smokers. Volunteer daily smokers were recruited into a randomized, placebo-controlled study via community media, colleges and the army (aged 18-26 years). Those subjects with light tobacco dependence were randomized to (i) placebo patch (n = 86) and (ii) nicotine patch 10 mg/16 hr for 8 weeks (n = 94), and those with stronger dependence to (iii) nicotine patch 15 mg/16 hr for 8 weeks (n = 51) and (iv) varenicline for 12 weeks (n = 60). The primary outcome variable was self-reported smoking abstinence at week 12. Secondary outcome variables were self-reported smoking abstinence at weeks 4 and 26, and self-reported abstinence verified by saliva cotinine level at week 12. The prevalence of self-reported smoking abstinence did not differ statistically significantly in light smokers during the follow-up (week 4: 19.8% for placebo patch and 26.6% for nicotine patch 10 mg/16 hr; week 12: 17.4% versus 23.4%; week 26: 15.1% versus 20.2%), but the groups of heavy smokers differed significantly for 12 weeks (week 4: 19.6% for nicotine patch 15 mg/16 hr and 73.3% for varenicline, p < 0.001; week 12: 15.7% versus 36.7%, p = 0.018). This statistically significant difference did not endure for the entire follow-up (week 26: 9.8% versus 18.3%, p = 0.280). However, saliva cotinine verified abstinence at week 12 did not support self-reported abstinence. Varenicline may be more effective than the nicotine patch as a smoking cessation pharmacotherapy among young adult heavy smokers in the short-term.

    Quitting smoking benefits older individuals, yet few recent studies have described older smokers. The goal of this paper was to test a series of hypotheses about differences between smokers aged 50 years or older (50+) and those younger than age 50 (<50) presenting to the same treatment facility during 2002-2004 for participation in two randomized clinical trials: one exclusively for smokers aged 50+, and a second open to smokers aged 18 or older. As predicted, smokers aged 50+ were more tobacco dependent, had better psychological functioning, and had poorer physical functioning than those aged <50. Contrary to predictions, we found no differences in motivation to quit cigarette smoking or in alcohol use. Women aged 50+ were less likely to report marijuana use than women aged <50, and less likely than men to receive a positive diagnosis for alcohol abuse. Despite higher scores on measures of tobacco dependence, older smokers were less likely to be diagnosed as tobacco dependent or as having tobacco withdrawal using DSM-IV criteria. Rates of DSM-IV alcohol abuse and dependence were high in both age groups but were higher for smokers aged <50. We found no striking differences between studies in reasons for exclusion, but in both the proportion of individuals excluded due to current antidepressant use was high. Implications for the assessment and treatment of older adults are discussed. PMID:18324565

Despite higher scores on measures of tobacco dependence, older smokers were less likely to be diagnosed as tobacco dependent or having tobacco withdrawal using DSM-IV criteria. Rates of DSM-IV alcohol abuse and dependence were high in both age groups but were higher for smokers <50. There were no striking differences between studies in reasons for exclusion, but in both, the proportion of individuals excluded due to current antidepressant use was high. Implications for the assessment and treatment of older adults are discussed. PMID:18324565

    This study tested the hypothesis that changes in momentary affect, abstinence motivation, and confidence would predict lapse risk over the next 12-24 hr using Ecological Momentary Assessment (EMA) data from smokers attempting to quit smoking. One hundred and three adult, daily, treatment-seeking smokers recorded their momentary affect, motivation to quit, abstinence confidence, and smoking behaviors in near real time with multiple EMA reports per day using electronic diaries postquit. Multilevel models indicated that initial levels of negative affect were associated with smoking, even after controlling for earlier smoking status, and that short-term increases in negative affect predicted lapses up to 12, but not 24, hr later. Positive affect had significant effects on subsequent abstinence confidence, but not motivation to quit. High levels of motivation appeared to reduce increases in lapse risk that occur over hours although momentary changes in confidence did not predict lapse risk over 12 hr. Negative affect had short-lived effects on lapse risk, whereas higher levels of motivation protected against the risk of lapsing that accumulates over hours. An increase in positive affect was associated with greater confidence to quit, but such changes in confidence did not reduce short-term lapse risk, contrary to expectations. Relations observed among affect, cognitions, and lapse seem to depend critically on the timing of assessments.

    Recent research on adolescent smokers suggests that there are important differences in the types of nicotine dependence (ND) symptoms that emerge and different patterns of ND symptoms. The purpose of this study was to use data from the longitudinal Social and Emotional Contexts of Adolescent Smoking Patterns Study to identify latent subgroups of adolescent experimental and nondaily smokers varying in number and types of endorsed ND symptoms. Profiles were identified using baseline level of smoking, individual patterns of ND symptoms and other ND risk factors. Discrete time survival analysis was used to examine profile differences in probability of becoming daily smokers 48 months later. Four distinct subgroups of smokers with different patterns of smoking behavior, ND symptoms, and alcohol and other substance use emerged. Heavier smoking adolescents with high symptom endorsement, particularly the need to smoke in the morning, were most likely to become daily smokers 48 months later. A subgroup of social smokers had high smoking exposure and symptom endorsement (except need to smoke in the morning), and high levels of other substance use. Despite lower rates of smoking frequency and quantity compared to the heavier smoking class, 36% of these adolescents smoked daily by 48 months, with a steeper decline in survival rates compared to other lighter smoking classes. Morning smoking symptoms and symptoms prioritizing smoking (i.e., choosing to spend money on cigarettes instead of lunch or smoking when ill or where smoking is forbidden) might quickly identify adolescent non-daily smokers with more severe dependence and higher risk for daily smoking. A focus on skills for avoiding social situations involving use of alcohol and other drugs and reducing peer smoking influences may be an important focus for reducing smoking and other substance use among social smokers.

    Since mainstream smoke is highly enriched in /sup 210/Pb, alpha radiation from inhaled cigarette smoke particles has been proposed as a cancer-producing agent in cigarette smokers. /sup 210/Po and /sup 210/Pb have been observed in tobacco, cigarette smoke and in the lungs of smokers. Since /sup 210/Pb is highly enriched in mainstream smoke, there have been estimates of yearly excesses of /sup 210/Pb in the lungs of one-pack-a-day smokers of 3 to 10 pCi (0.11 to 0.37 Bq). The ORNL Whole Body Counter was used to verify this estimate by the methodology of high-resolution, in vivo gamma spectrometry. Measurements were made on 113 adult male non-radiation workers who have either smoked at least one pack of cigarettes per day for at least five years, or have never smoked cigarettes. An analysis-of-variance table was generated based on the Pb-ratio for each individual which revealed that there was no statistically significant increase in the amount of /sup 210/Pb in the lungs of smokers over those of non-smokers. Sources of error are also discussed.

    Hypertensive patients who smoke are in particular need of lifestyle modification counseling because they are at increased risk for poorer outcomes. The authors examined whether hypertensive smokers were more or less likely than nonsmokers to report receiving recommendations for diet, salt intake, exercise, alcohol use, and medication and whether receipt of recommendations was differentially associated with lifestyle changes among smokers vs nonsmokers. In an analysis of data from the 2011 Behavioral Risk Factor Surveillance System on a representative sample of hypertensive adults from 9 US states (N=23,093), smokers were less likely than nonsmokers to report being told by a provider to exercise (odds ratio [OR], 0.66; P<.001) and change their diet (OR, 0.83; P<.05). Receiving dietary recommendations was more strongly associated with self-reported dietary improvements among smokers (OR, 7.08; P<.001) compared with nonsmokers (OR, 4.17; P<.001) P<.01. Delivery of counseling may vary by smoking status. When provided, lifestyle counseling may be equally or more effective for smokers compared with nonsmokers.

  6. Young smokers' attitudes about methods for quitting smoking: barriers and benefits to using assisted methods.

    There is currently little information about how smokers choose a particular method to stop smoking. Young adult smokers rated likelihood of success as the most important criteria for choosing a stop-smoking method but saw only a small difference in likelihood of success between common assisted and unassisted methods. They rated cost, convenience, and quitting on own as other important criteria. Almost all would choose an unassisted method for their next quit attempt. The smokers then rated their probability of using a stop-smoking program or a nicotine patch under various conditions of cost, convenience, and increased likelihood of success. The results showed that the smokers indicated a moderate-high probability of using the two assisted methods under assumptions of convenience and likelihood of success that are currently realistic. However, they were extremely sensitive to cost of the method. When the stop-smoking program or nicotine patch was free, the estimated probability of use was over 50% for all tested conditions; however, at a cost of +25 the estimated probability dropped below 20% for all conditions. Young smokers would be likely to choose assisted methods when attempting to stop if they appreciated the increased likelihood of success with these methods and if the cost was not high.

    This study was designed to determine the levels of microminerals (manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), chromium (Cr)) and heavy metals (cadmium (Cd), lead (Pb) and nickel (Ni)) in some tubers, legumes and cereals obtained from the markets in Abeokuta city, South-West Nigeria. The food samples were digested by dry ashing procedure and their minerals were determined by atomic absorption spectrophotometer. The results show mean values of 1.67-32.00, 7.25-61.58, 1.59-10.56, 6.65-46.99, 0.02-0.58, <0.01-0.09, <0.08, and 0.06-0.14 mg/kg for Mn, Fe, Cu, Zn, Cr, Cd, Pb and Ni respectively. The levels of these metals in all the samples analysed were within the ranges reported for similar tubers, legumes and cereals from various parts of the world. The daily intakes of the metals through tubers, legumes and cereals were found to be lower than the provisional tolerable daily intakes proposed by Joint FAO/WHO Expert Committee on Food Additives.

    Background Both mHealth and eHealth interventions for smoking cessation are rapidly being developed and tested. There are no data on use of mHealth and eHealth technologies by smokers in general or by smokers who are not motivated to quit smoking. Objective The aims of our study were to (1) assess technology use (eg, texting, social media, Internet) among smokers in the United States and United Kingdom, (2) examine whether technology use differs between smokers who are motivated to quit and smokers who are not motivated to quit, (3) examine previous use of technology to assist with smoking cessation, and (4) examine future intentions to use technology to assist with smoking cessation. Methods Participants were 1000 adult smokers (54.90%, 549/1000 female; mean age 43.9, SD 15.5 years; US: n=500, UK: n=500) who were recruited via online representative sampling strategies. Data were collected online and included demographics, smoking history, and frequency and patterns of technology use. Results Among smokers in general, there was a high prevalence of mobile and smartphone ownership, sending and receiving texts, downloading and using apps, using Facebook, and visiting health-related websites. Smokers who were unmotivated to quit were significantly less likely to own a smartphone or handheld device that connects to the Internet than smokers motivated to quit. There was a significantly lower prevalence of sending text messages among US smokers unmotivated to quit (78.2%, 179/229) versus smokers motivated to quit (95.0%, 229/241), but no significant differences between the UK groups (motivated: 96.4%, 239/248; unmotivated: 94.9%, 223/235). Smokers unmotivated to quit in both countries were significantly less likely to use a handheld device to read email, play games, browse the Web, or visit health-related websites versus smokers motivated to quit. US smokers had a high prevalence of app downloads regardless of motivation to quit, but UK smokers who were motivated to quit

    The current study deals with the heart rate variability (HRV) and wavelet-based ECG signal analysis of smokers and non-smokers. The results of HRV indicated dominance towards the sympathetic nervous system activity in smokers. The heart rate was found to be higher in case of smokers as compared to non-smokers ( p < 0.05). The frequency domain analysis showed an increase in the LF and LF/HF components with a subsequent decrease in the HF component. The HRV features were analyzed for classification of the smokers from the non-smokers. The results indicated that when RMSSD, SD1 and RR-mean features were used concurrently a classification efficiency of > 90 % was achieved. The wavelet decomposition of the ECG signal was done using the Daubechies (db 6) wavelet family. No difference was observed between the smokers and non-smokers which apparently suggested that smoking does not affect the conduction pathway of heart.

    Full-dose prophylaxis treatment for persons with haemophilia is not affordable in China due to its economic constraints, particularly in adults requiring higher clotting factor (CFC) doses. Low-dose tertiary prophylaxis for adults with severe haemophilia A (SHA) in Beijing became feasible and implemented when government insurance covering 85% CFC cost in Beijing began in December 2009. The aim of this study was to evaluate the benefits of low-dose tertiary prophylaxis in SHA adults. Analysis of data on 33 patients on low-dose tertiary prophylaxis (5-10 IU/kg, two to three times per week) at the Haemophilia Treatment Center, Peking Union Medical College Hospital between December 2009 and December 2013. The 33 patients (age 18-60 years, mean 33.4) were on prophylaxis for 20.8 ± 9.9 months (compared with prior on-demand therapy for 20.0 ± 11.7 months). Prophylaxis resulted in significant decrease in annual bleeding rate (ABR, 11.8 ± 7.6 vs. 41.5 ± 20.7, 71.1% reduction, P < 0.0001), and significant improvement in Functional Independence Score in Haemophilia (FISH) measurement reflecting improvement in self-care and mobility. Radiologic (Pettersson) joint score was neither improved nor deteriorated. Ten of the 33 patients originally wheel chair and bed-bound began to walk and function independently in their daily lives. Low-dose tertiary prophylaxis for adults with SHA in China is feasible and beneficial. Although the average ABR remained high, a significant improvement in self-care and mobility measured by FISH was observed. These promising clinical experiences form the basis for further formal studies with more defined therapeutic protocol and outcome measures for affordable prophylaxis regimens in haemophilia adults in China.

  11. How do smokers control their cigarette expenditures?

    When faced with high cigarette prices, smokers can potentially control cigarette expenditures by limiting consumption or seeking cheaper cigarettes. The present study examined both these options and whether the use of price-minimizing strategies (the second option) could counteract a further price increase without smokers having to reduce consumption. Data for 5,109 smokers who purchased manufactured cigarettes were from the 2002 cross-sectional, population-based, random-digit-dialed California Tobacco Survey. We used logistic regression to examine which smokers used consumption-limiting or price-minimizing strategies, and multiple linear regression to determine how much price-minimizing strategies reduced the average price paid per pack. Overall, 32.3% of California smokers said they limited consumption and 74.1% used at least one of the five price-minimizing strategies identified: choosing cheaper retail outlets (61.1%), using promotional offers (35.2%), choosing cheaper brands (28.7%), purchasing by the carton (27.7%), and using low-tax or nontaxed sources (6.3%). Different groups of smokers used different strategies. Except for the use of promotional offers, all price-minimizing strategies significantly reduced the price paid per pack. Carton purchasers saved 1.01 US dollars/pack, and those buying from low-tax or nontaxed sources saved 1.23 US dollars/pack. However, pack buyers were reluctant to purchase cartons, mostly because they thought they might smoke too much, or because they considered the upfront cost unaffordable. The average California smoker could potentially save 0.33-0.66 US dollars/pack or 6.00-12.00 US dollars/month by using other price-minimizing strategies. Reducing consumption by 3 cigarettes/day could save a smoker 18.00 US dollars/month. Whereas price-minimizing strategies appeared to save money, cutting consumption could save even more. Thus further substantial tax increases would likely have the desired effect. PMID:16085532

    Objective Observational research suggests that placing graphic images on cigarette warning labels can reduce smoking rates, but field studies lack experimental control. Our primary objective was to determine the psychological processes set in motion by naturalistic exposure to graphic vs. text-only warnings in a randomized clinical trial involving exposure to modified cigarette packs over a 4-week period. Theories of graphic-warning impact were tested by examining affect toward smoking, credibility of warning information, risk perceptions, quit intentions, warning label memory, and smoking risk knowledge. Methods Adults who smoked between 5 and 40 cigarettes daily (N = 293; mean age = 33.7), did not have a contra-indicated medical condition, and did not intend to quit were recruited from Philadelphia, PA and Columbus, OH. Smokers were randomly assigned to receive their own brand of cigarettes for four weeks in one of three warning conditions: text only, graphic images plus text, or graphic images with elaborated text. Results Data from 244 participants who completed the trial were analyzed in structural-equation models. The presence of graphic images (compared to text-only) caused more negative affect toward smoking, a process that indirectly influenced risk perceptions and quit intentions (e.g., image->negative affect->risk perception->quit intention). Negative affect from graphic images also enhanced warning credibility including through increased scrutiny of the warnings, a process that also indirectly affected risk perceptions and quit intentions (e.g., image->negative affect->risk scrutiny->warning credibility->risk perception->quit intention). Unexpectedly, elaborated text reduced warning credibility. Finally, graphic warnings increased warning-information recall and indirectly increased smoking-risk knowledge at the end of the trial and one month later. Conclusions In the first naturalistic clinical trial conducted, graphic warning labels are more effective

    Excessive alcohol use in young adults is associated with greater impulsivity and neurobiological alterations in executive control systems. The maximum number of drinks consumed during drinking occasions ('MaxDrinks') represents a phenotype linked to vulnerability of alcohol use disorders, and an increase, or 'escalation', in MaxDrinks may be indicative of greater risk for problematic drinking. Thirty-six young adult drinkers performed a Go/No-Go task during fMRI, completed impulsivity-related assessments, and provided monthly reports of alcohol use during a 12-month follow-up period. Participants were characterized by MaxDrinks at baseline and after follow-up, identifying 18 escalating drinkers and 18 constant drinkers. Independent component analysis was used to investigate functional brain networks associated with response inhibition, and relationships with principal component analysis derived impulsivity-related domains were examined. Greater baseline MaxDrinks was associated with an average reduction in the engagement of a right-lateralized fronto-parietal functional network, while an escalation in MaxDrinks was associated with a greater difference in fronto-parietal engagement between successful inhibitions and error trials. Escalating drinkers displayed greater impulsivity/compulsivity-related domain scores that were positively associated with fronto-parietal network engagement and change in MaxDrinks during follow-up. In young adults, an escalating MaxDrinks trajectory was prospectively associated with altered fronto-parietal control mechanisms and greater impulsivity/compulsivity scores. Continued longitudinal studies of MaxDrinks trajectories, functional network activity, and impulsivity/compulsivity-related features may lend further insight into an intermediate phenotype vulnerable for alcohol use and addictive disorders.

    The purpose of this study was to examine in a systematic, controlled fashion the reactions of smokers to scientifically correct information about the risks of smoking Light cigarettes (about 6-15 mg tar by the FTC method). Random-digit dialing, computer-assisted telephone interviews were used to locate daily smokers of Light cigarettes. In an experimental design, smokers were randomly assigned to listen (n = 293) or not (n = 275) to a persuasive simulated radio message on the risks of Light cigarettes; 108 of those who did not listen to the message in the first part of the interview were played the message in the second part, to evaluate some repeated-measures effects. Those who heard the message were more likely to report that one Light cigarette could give a smoker the same amount of tar as one Regular cigarette and that Light cigarettes were more dangerous: 55% said the message made them think more about quitting and 46% said the message increased the amount they wanted to quit; 42% said that after hearing the message they thought Light cigarettes were more dangerous. Using the Theory of Planned Behavior, structural equation modeling analysis indicated that the message acted to increase intention to quit smoking by increasing the desire to quit smoking. Seventy-three per cent of the smokers agreed that it was important to play such messages widely on the radio; 77% agreed that there should be a warning on packs that vent blocking increases tar; 61% agreed that the location of filter vents should be marked. The majority of smokers of Light cigarettes seem to value being informed that Light cigarettes are as dangerous for them as Regular cigarettes, and this information increases their intentions to quit smoking.

    Smoking causes subfertility due to deterioration of spermatozoa including decreased concentration and abnormal morphology. Although evidence on the deleterious effects of smoking on spermatozoa parameters is well known, its interference with cryopreservation is not clear. This study aimed to investigate the effects of cryopreservation on sperm parameters and DNA fragmentation in non-smokers and smokers. Semen samples were obtained from 40 normospermic male volunteers of whom 20 were non-smokers and 20 smokers. Samples were analyzed in terms of motility, concentration, morphology, and DNA fragmentation before freezing and 1 and 3 months after freezing and thawing. Ultrastructural alterations were investigated by transmission electron microscopy. Sperm morphology seemed to be more affected after cryopreservation in samples obtained from smokers. Ultrastructural examination showed alterations in the integrity of the membranes and increased subacrosomal swelling. Before freezing, the increase in DNA fragmentation rate in smokers was not statistically significant compared to that of non-smokers. However, after thawing, the DNA fragmentation rates were significantly high in both non-smokers and smokers compared to their respective rates before freezing. The extent of the increase in DNA fragmentation rate was significantly higher in smokers after thawing compared to that of non-smokers. In conclusion, cryopreservation causes alterations in membrane integrity and increases DNA fragmentation, thus triggering relatively negative effects on the sperm samples of smokers compared to that of non-smokers.

    The present investigation examined intrinsic and extrinsic reasons for quitting among daily cigarette smokers with posttraumatic stress disorder (PTSD) as compared to clinical daily smokers with other anxiety and mood disorders (AM) and daily smokers with no current Axis I psychopathology (C) prior to a self-guided quit attempt. It was hypothesized that (1) the PTSD group would report greater intrinsic (ie, self-control and health concerns) reasons for quitting smoking, and (2) among those with PTSD, anxiety sensitivity (fear of anxiety; AS) would predict greater intrinsic reasons for quitting smoking. Participants were 143 (58.7% female; M(age) = 29.66 years, SD = 11.88) daily cigarette smokers. Partially consistent with prediction, the PTSD group reported significantly greater self-control intrinsic reasons for quitting, but not health concern intrinsic reasons, than the C group (p < .01). The PTSD group also reported greater immediate reinforcement extrinsic reasons for quitting than the C group (p < .05). The PTSD and AM groups did not significantly differ on any reasons for quitting. Also partially consistent with hypotheses, higher levels of anxiety sensitivity in daily smokers with Axis I psychopathology (both PTSD and AM groups) significantly predicted greater self-control intrinsic reasons for quitting. AS did not significantly predict immediate reinforcement extrinsic reasons for quitting. The current findings suggest that individuals with PTSD and other psychopathology may have unique motivations for quitting smoking that could be usefully explored within smoking cessation treatment programs.

    Summary Background Co-trimoxazole prophylaxis can reduce mortality from untreated HIV infection in Africa; whether benefits occur alongside combination antiretroviral therapy (ART) is unclear. We estimated the effect of prophylaxis after ART initiation in adults. Methods Participants in our observational analysis were from the DART randomised trial of management strategies in HIV-infected, symptomatic, previously untreated African adults starting triple-drug ART with CD4 counts lower than 200 cells per μL. Co-trimoxazole prophylaxis was not routinely used or randomly allocated, but was variably prescribed by clinicians. We estimated effects on clinical outcomes, CD4 cell count, and body-mass index (BMI) using marginal structural models to adjust for time-dependent confounding by indication. DART was registered, number ISRCTN13968779. Findings 3179 participants contributed 14 214 years of follow-up (8128 [57%] person-years on co-trimoxazole). Time-dependent predictors of co-trimoxazole use were current CD4 cell count, haemoglobin concentration, BMI, and previous WHO stage 3 or 4 events on ART. Present prophylaxis significantly reduced mortality (odds ratio 0·65, 95% CI 0·50–0·85; p=0·001). Mortality risk reduction on ART was substantial to 12 weeks (0·41, 0·27–0·65), sustained from 12–72 weeks (0·56, 0·37–0·86), but not evident subsequently (0·96, 0·63–1·45; heterogeneity p=0·02). Variation in mortality reduction was not accounted for by time on co-trimoxazole or current CD4 cell count. Prophylaxis reduced frequency of malaria (0·74, 0·63–0·88; p=0·0005), an effect that was maintained with time, but we observed no effect on new WHO stage 4 events (0·86, 0·69–1·07; p=0·17), CD4 cell count (difference vs non-users, −3 cells per μL [−12 to 6]; p=0·50), or BMI (difference vs non-users, −0·04 kg/m2 [−0·20 to 0·13); p=0·68].

    2011-01-01

    Background The prevalence of waterpipe tobacco smoking (WTS) in the Middle East region and worldwide is increasing. There is evidence to indicate both short term and long term health effects of WTS, resulting in the issuance of an advisory note by the World Health Organization. Methods This research aimed at gaining an in-depth understanding of the factors contributing to the rise in WTS in Lebanon. Qualitative focus groups (25) and in-depth interviews (9) were conducted with adults in Lebanon in 2007. Participants were recruited to represent diversity in smoking status, gender, age groups and urban/rural residence. The interviews and focus groups were thematically analyzed, and recurrent themes noted and summarized. Results The main themes identified were availability, affordability, innovation, influence of media, lack of a policy framework, and the sensory characteristics evoked from WTS. Men and women, smokers and non-smokers, and younger and older participants differed in their emphases on the above themes. These themes, though specific to waterpipe, are similar to themes manipulated by the cigarette industry, and eventually controlled through tobacco control policies. Conclusions Understanding reasons behind the rise in waterpipe tobacco use is important if appropriate prevention, cessation, and policy interventions are to be formulated. Strict adherence to the FCTC is warranted, with careful and vigilant attention that all tobacco products are covered by laws in both high as well as middle to lower income countries. PMID:21569577

    The present study examined the heart rate turbulence (HRT) and heart rate variability (HRV) parameters in healthy young smokers (<40 years) to assess the effects of smoking on cardiac autonomic function. The study included 75 smokers with a history of habitual smoking for at least 1 year (41 males and 34 females; mean age, 29.3 ± 7.3 years) and 30 nonsmokers (hospital staff; 16 males and 14 females; mean age, 29.0 ± 6.1 years). Addiction to smoking was evaluated using the modified Fagerström test for nicotine-dependence index (NDI). HRT, HRV, basic clinical and echocardiographic, and Holter test parameters were compared between groups. No significant differences between the two groups were found in the basic clinical and echocardiographic variables. Turbulence onset (TO) was significantly higher in the smoking group than in the controls, and turbulence slope was significantly lower in the smokers, than in the controls (p < 0.05). Standard deviation of all normal-to-normal (NN) interval index (SDNNI) was the only HRV parameter that was significantly different between the smoking and control groups (p < 0.05). The NDI was positively correlated with the TO (p < 0.05). Smoking impairs the baroregulatory function in healthy young smokers, particularly the HRT parameters and SDNNI. Our findings highlight the importance of complete smoking cessation.

    In two studies, we examined nonsmokers' perceptions of smokers and consequences of the perceptions. In Study 1, smokers answered questions about their sense of self, dependence on smoking, and motivation to quit. Nonsmokers answered questions about their perceptions of these characteristics. Differences between smokers' self-descriptions and nonsmokers' perceptions were observed. Study 2 asked nonsmokers to judge two types of smokers for which the descriptions were based on Study 1 findings. Results showed that nonsmokers held a more negative attitude about and were less willing to engage in different close relationships with the smoker who was described in terms of nonsmokers' perceptions rather than smokers' reports. Attitude mediated the relationship between type of smoker and willingness to date a smoker.

    Multi-sensory stimulation provided in a Snoezelen room is being used increasingly for individuals with mental retardation and mental illness to facilitate relaxation, provide enjoyment, and inhibit behavioral challenges. We observed aggressive and self-injurious behavior in three groups of 15 individuals with severe or profound mental retardation and mental illness before, during, and after being in a Snoezelen room. All participants were receiving psychotropic medication for their mental illness and function-derived behavioral interventions for aggression, self-injury, or both. Using a repeated measures counterbalanced design, each group of participants was rotated through three experimental conditions: Activities of Daily Living (ADL) skills training, Snoezelen, and Vocational skills training. All other treatment and training activities specified in each individual's person-centered plan were continued during the 10-week observational period. Both aggression and self-injury were lowest when the individuals were in a Snoezelen room, followed by Vocational skills training and ADL skills training. The levels in the Snoezelen room were significantly lower than in both the other conditions for aggression but only in ADL skills training for self-injury. The difference in levels before and after Snoezelen were statistically significant with self-injury but not with aggression. The order of conditions showed no significant effect on either behavior. Snoezelen may provide an effective context for reducing the occurrence of self-injury and aggression.

    Background Suboptimal vitamin D (vitD) status is common in children and young adults infected with human immunodeficiency virus (HIV). The vitD supplemental dose needed to normalize vitD status in this population is unknown. Methods In this double-blind trial, subjects infected with HIV ages 8.3 to 24.9 years were randomized to vitD3 supplementation of 4000 IU/day or 7000 IU/day and evaluated at 6 and 12 week for changes in vitD status and HIV indicators. A dose was considered unsafe if serum calcium was elevated (above age and sex-specific range) associated with elevated serum 25 hydroxyvitamin D (25(OH)D); >160 ng/mL). Results At baseline, 95% of subjects (n = 44; 43% with perinatally acquired HIV, 57% with behaviorally acquired HIV) had a suboptimal serum 25(OH)D concentration of <32 ng/mL (mean ± standard deviation, 19.3 ± 7.4; range, 4.4–33.6 ng/mL). After 12 weeks (main outcome) of D3 supplementation, both D3 doses were safe and well tolerated, with no evidence of elevation of serum calcium concentrations or deterioration in HIV immunologic or virologic status. Sufficient vitD status, defined as serum 25(OH)D ≥32 ng/mL, was achieved in 81% of all subjects, and only the 7000 IU/day group (86%) achieved this a priori efficacy criterion in >80% of subjects. Change in serum 25(OH)D did not differ between HIV acquisition groups. Conclusions A 7000 IU/day D3 supplementation was safe and effective in children and young adults infected with HIV.

    The ability to perform instrumental activities of daily living (IADL) is important for one's level of independence. A high incidence of limitations in IADL is seen in older adults with intellectual disabilities (ID), which is an important determinant for the amount of support one needs. The aim of this study was to assess the predictive value of physical fitness for the ability to perform IADL, over a 3-year follow-up period, in 601 older adults with ID. At baseline, an extensive physical fitness assessment was performed. In addition, professional caregivers completed the Lawton IADL scale, both at baseline and at follow-up. The average ability to perform IADL declined significantly over the 3-year follow-up period. A decline in the ability to perform IADL was seen in 44.3% of the participants. The percentage of participants being completely independent in IADL declined from 2.7% to 1.3%. Manual dexterity, balance, comfortable and fast gait speed, muscular endurance, and cardiorespiratory fitness were significant predictors for a decline in IADL after correcting for baseline IADL and personal characteristics (age, gender, level of ID, and Down syndrome). This can be interpreted as representing the predictive validity of the physical tests for a decline in IADL. This study shows that even though older adults with ID experience dependency on others due to cognitive limitations, physical fitness also is an important aspect for IADL, which stresses the importance of using physical fitness tests and physical fitness enhancing programs in the care for older adults with ID.

    Background Cigarette smokers are more susceptible to periodontal diseases and are more likely to be infected with Porphyromonas gingivalis than non-smokers. Furthermore, smoking is known to alter the expression of P. gingivalis surface components and to compromise IgG generation. The aim of this study was to evaluate whether IgG response to P. gingivalis is suppressed in smokers in vivo and whether previously established in vitro tobacco-induced phenotypic P. gingivalis changes would be reflected in vivo. Methods We examined the humoral response to several P. gingivalis strains as well as specific tobacco-regulated outer membrane proteins (FimA and RagB) by ELISA in biochemically-validated (salivary cotinine) smokers and non-smokers with chronic (CP, n = 13) or aggressive (AP, n = 20) periodontitis. We also monitored the local and systemic presence of P. gingivalis DNA by PCR. Results Smoking was associated with decreased total IgG responses against clinical (10512, 5607, and 10208C; all p < 0.05) but not laboratory (ATCC 33277, W83) P. gingivalis strains. Smoking did not influence IgG produced against specific cell surface proteins, although a non-significant pattern towards increased total FimA-specific IgG in CP subjects, but not AP subjects, was observed. Seropositive smokers were more likely to be infected orally and systemically with P. gingivalis (p < 0.001), as determined by 16S RNA analysis. Conclusions Smoking alters the humoral response against P. gingivalis, strengthening the evidence that mechanisms of periodontal disease progression in smokers may differ from non-smokers with the same disease classification.

    Introduction Despite the strong relationship between smoking and health-related consequences, very few smokers quit. Heavy drinking is a significant risk factor for health consequences, and is implicated in persistent smoking and less success at quitting smoking. Self-efficacy (SE) to abstain from smoking is an important determinant of smoking outcomes and may link alcohol use to poor quit rates. Even though research has demonstrated a strong association between drinking and smoking, and the multiplicative effect of these substances on cancer-related, heavy-drinking smokers has been largely ignored in the literature. Further, research has not taken advantage of innovative methods, such as ecological momentary assessment, to capture the impact of daily factors on smoking cessation outcomes in this particular group. The proposed study identifies daily changing factors that impede or promote SE and future smoking cessation efforts in risky-drinking smokers. Methods and analysis This is an observational study of 84 regular smokers (≥10 cigarettes per day) who drink at risky levels, report a desire to quit in the next 6 months, and show no evidence of psychiatric disturbance, severe history of alcohol withdrawal or drug dependence (excluding nicotine and caffeine). Participants report on their smoking, alcohol consumption and SE related to smoking twice a day for 28 days using interactive voice response (IVR) surveys. Multilevel regression and path models will examine within-person daily associations among drinking, smoking and SE, and how these variables predict the likelihood of future smoking behaviour at 1 and 6 months follow-up. Ethics and dissemination This protocol was approved by an accredited Institutional Review Board. The findings will help us understand the factors that promote or impede smoking cessation among a high-risk group of smokers (heavy-drinking smokers) and will be disseminated through peer-reviewed journal articles and presentations at

    Losses of chromosomes 1p and 19q are deemed correlated with diagnosis of oligodendroglioma, higher chemosensitivity and better prognosis. We reviewed the literature to evaluate the usefulness of these correlations in daily clinical practice. The rates of deletions relative to histology (WHO classifications) were extracted from 33 studies, including 2666 patients. The 1p deletions and 1p19q codeletion mean rates were respectively 65.4 and 63.3% in oligodendrogliomas, 28.7 and 21.6% in oligoastrocytomas, 13.2 and 7.5% in astrocytomas, 11.6 and 2.9% in glioblastomas. The presence of 1p deletion and 1p19q codeletion were strongly correlated with the histological diagnosis corresponding to oligodendroglioma. Calculation of specificity, sensitivity, predictive positive values and false negative rates suggests that presence of deletion 1p or codeletion represents a strong argument in favor of the diagnosis of oligodendroglioma. However, considering the high false negative rate, absence of such deletions does not rule out the diagnosis. In grade 3 oligodendroglial tumors, the probability of responding to chemotherapy, and the duration of response, were higher when codeletions were present. This suggests that, in these tumors, the presence of codeletion is a strong argument in favor of adjuvant chemotherapy. However, chemotherapy should not be systematically excluded when codeletions are absent, as the chances of response are about 33% in this situation. Data concerning low-grade gliomas were more controversial. Oligodendroglial tumors with 1p deletion or 1p19q codeletion seemed to have a better prognosis, as five-year survival rates were 50% higher than in tumors without deletion. This might be explained by the correlation between 1p deletion and other identified prognosis factors: (1) higher chemosensitivity, (2) tumor location more frequently in the frontal lobe, leading to better resection and lower risk of neurological deficit, (3) slower growth rate, (4) higher risk

    Smokers with chronic obstructive pulmonary disease (COPD) appear to represent a hard-core group, and this presents a dilemma for chest physicians. A reduction in cigarette smoking benefits health, and nicotine replacement therapy (NRT) can aid smoking reduction. Hence we studied the efficacy of nicotine gum in helping hard-core smokers with severe COPD to quit. Seventeen smokers with severe COPD (FEV(1) 38-47% of predicted normal) who smoked >30 cigarettes/day but were unable to quit were encouraged to reduce their smoking as much as possible by using 4-mg nicotine gum. Five gradually reduced their daily tobacco consumption and, 18 months after starting NRT, were smoking an average of 6 cigarettes/day while still using nicotine gum. Compared to baseline, their respiratory symptoms had improved, and both FEV(1) and FVC had increased. There was no improvement in pulmonary function in the group of smokers who did not reduce their cigarette consumption. No adverse events relating to nicotine occurred among the patients who used NRT to reduce their smoking. We propose that this reduction approach should be considered for patients with respiratory disease who are unable or unwilling to stop smoking.

    The ability to recognize and label discrete emotions, termed emotion differentiation, is particularly pertinent to overall emotion regulation abilities. Patterns of deficient emotion differentiation have been associated with mood and anxiety disorders but have yet to be examined in relation to nicotine dependence. This study employed ecological momentary assessment to examine smokers' subjective experience of discrete emotions during 24-h of forced tobacco abstinence. Thirty daily smokers rated their emotions up to 23 times over the 24-hour period, and smoking abstinence was biologically verified. From these data, we computed individual difference measures of emotion differentiation, overall emotion intensity, and emotional variability. As hypothesized, heavy smokers reported poorer negative emotion differentiation than light smokers (d=0.55), along with more intense negative emotion (d=0.97) and greater negative emotion variability (d=0.97). No differences were observed in positive emotion differentiation. Across the sample, poorer negative emotion differentiation was associated with greater endorsement of psychological motives to smoke, including negative and positive reinforcement motives, while positive emotion differentiation was not.

    We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers.

    Background The majority of studies investigating the neurocognitive consequences of chronic smoking have been conducted with adults 60 years and older. Therefore, the scope of neurocognitive dysfunction associated with chronic cigarette smoking in middle age (i.e., 30–60 age range) has not been fully delineated. Methods Twenty-seven (44±9 years of age; 4 females) non-smoking and 30 smoking (49±8 years of age; 4 females) participants completed a comprehensive neurocognitive battery and measures of fine motor dexterity and postural stability. All participants were free of biomedical or psychiatric conditions that may have influenced neurocognitive and motor function. Results Smokers performed significantly worse than non-smokers on the following domains: auditory-verbal and visuospatial learning, visuospatial memory, cognitive efficiency, executive skills, general intelligence, processing speed, fine motor dexterity and postural stability. The differences between smokers and non-smokers evidenced moderate to strong effect sizes and were not mediated by age, education, vocational level, estimated verbal intelligence or alcohol consumption. In smokers, a greater number of lifetime years of smoking was related to poorer performance on measures of cognitive efficiency, processing speed and visuospatial skills. Conclusions Results from this middle-aged cohort replicated previous research and provides novel findings indicating that chronic smoking was associated with inferior performance on measures of general intelligence, visuospatial learning and memory and fine motor dexterity. Research that relates measures of neurobiological function/integrity to neurocognition is needed to better understand the mechanisms contributing to the poorer performance across multiple domains demonstrated by smokers.

    Introduction Since 2012, the Centers for Disease Control and Prevention has aired a national tobacco education campaign to encourage quitting, Tips From Former Smokers (Tips), which consists of graphic antismoking advertisements that feature former cigarette smokers. We evaluated phase 2 of the 2014 campaign by using a nationally representative longitudinal cohort. Methods Cigarette smokers who participated in a baseline survey were re-contacted for follow-up (n = 4,248) approximately 4 months later, immediately after the campaign’s conclusion. The primary outcomes were incidence of a quit attempt in the previous 3 months, intention to quit within 30 days, and intention to quit within 6 months during the postcampaign period. We used multivariate logistic regression models to estimate the odds of each outcome. We also stratified models by race/ethnicity, education, and mental health status. Postcampaign rates of quit attempts, intentions to quit, and sustained quits were also estimated. Results Exposure to the campaign was associated with increased odds of a quit attempt in the previous 3 months (OR, 1.17; P = .03) among baseline smokers and intentions to quit within the next 6 months (OR, 1.28; P = .01) among current smokers at follow-up. The Tips campaign was associated with an estimated 1.83 million additional quit attempts, 1.73 million additional smokers intending to quit within 6 months, and 104,000 sustained quits of at least 6 months. Conclusion The Tips campaign continued to have a significant impact on cessation-related behaviors, providing further justification for the continued use of tobacco education campaigns to accelerate progress toward the goal of reducing adult smoking in the United States.

    Introduction: The aim of this study was to examine knowledge and attitudes to lower harm alternatives to cigarettes among New Zealand (NZ) smokers. Methods: The NZ arm of the International Tobacco Control Policy Evaluation Survey (ITC Project) utilizes the NZ Health Survey (a national sample). From this sample, we surveyed adult smokers (N = 1,376). Results: Knowledge about smokeless tobacco was poor, with only 16% regarding such products as less harmful than ordinary cigarettes. Only 7% considered such products to be “a lot less” harmful. When participants were asked to assume that these products were much less harmful than cigarettes, 34% of smokers stated that they would be interested in trying smokeless tobacco products, with another 11% saying “maybe” or “don't know.” In the multivariate analysis, Māori smokers were significantly more interested in trying smokeless products than Europeans in all 3 models considered (e.g., Model 1: adjusted odds ratio [AOR] = 1.71, 95% CI = 1.23–2.37). There was also significantly increased interest for those concerned about the impact of smoking on health and quality of life in the future (AOR = 1.44, 95% CI = 1.17–1.78). But interest did not vary significantly by 2 measures of socioeconomic status and varied inconsistently by 2 measures of financial stress. Discussion: The finding that one third of smokers said that they would be interested in trying smokeless products suggests that these products could have a role as part of a tobacco epidemic endgame that phases out smoked tobacco. Differences in interest level by ethnic group may be relevant to stimulating further work in this area (e.g., among those health workers concerned for smokers with the highest need to quit).

    The objective of this research was to compare the response of adult smokers in Malaysia to newly proposed pictorial cigarette warnings against the current text-only warnings. The study population included 140 adult male smokers who were enrolled in a randomized trial to view either the new pictorial warnings (intervention) or the old text-only warnings (control). Participants completed pre-exposure and post-exposure questionnaires that assessed their awareness of the health risks of smoking, response to the package warnings, and interest in quitting smoking. Exposure to the pictorial warnings resulted in increased awareness of the risks of smoking, stronger behavioral response to the warnings and increased interest in quitting smoking. The new warnings in Malaysia will increase smokers' knowledge of the adverse health effects of smoking and have a positive effect on interest in quitting.

    Background Evidence consistently shows that almond consumption beneficially affects lipids and lipoproteins. Almonds, however, have not been evaluated in a controlled‐feeding setting using a diet design with only a single, calorie‐matched food substitution to assess their specific effects on cardiometabolic risk factors. Methods and Results In a randomized, 2‐period (6 week/period), crossover, controlled‐feeding study of 48 individuals with elevated LDL‐C (149±3 mg/dL), a cholesterol‐lowering diet with almonds (1.5 oz. of almonds/day) was compared to an identical diet with an isocaloric muffin substitution (no almonds/day). Differences in the nutrient profiles of the control (58% CHO, 15% PRO, 26% total fat) and almond (51% CHO, 16% PRO, 32% total fat) diets were due to nutrients inherent to each snack; diets did not differ in saturated fat or cholesterol. The almond diet, compared with the control diet, decreased non‐HDL‐C (−6.9±2.4 mg/dL; P=0.01) and LDL‐C (−5.3±1.9 mg/dL; P=0.01); furthermore, the control diet decreased HDL‐C (−1.7±0.6 mg/dL; P<0.01). Almond consumption also reduced abdominal fat (−0.07±0.03 kg; P=0.02) and leg fat (−0.12±0.05 kg; P=0.02), despite no differences in total body weight. Conclusions Almonds reduced non‐HDL‐C, LDL‐C, and central adiposity, important risk factors for cardiometabolic dysfunction, while maintaining HDL‐C concentrations. Therefore, daily consumption of almonds (1.5 oz.), substituted for a high‐carbohydrate snack, may be a simple dietary strategy to prevent the onset of cardiometabolic diseases in healthy individuals.

Measurements Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months. Results Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=−1.6–4.3; BI=0.6, 95% CI=−0.2–1.4) or 7 (FIM=0.8, 95% CI=−2.2–3.8; BI=0.6, 95% CI=−0.3–1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8–6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months. Conclusion In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.

    Introduction Smoking in long term is not only responsible for cancerous changes but is also one of the reasons of altered taste sensation in smokers. These taste changes are hypothesized to be due to reduction in density of fungiform papillae on the dorsum of the tongue. Aim The aim of this study was to assess the relationship between fungiform papillae count, blood Red Cell Distribution Width (RDW) and electrogustometric thresholds in smokers and non-smokers. Materials and Methods Fungiform papillae count was assessed using digital photography and imaging software while electrogustometric thresholds were assessed using modified Transcutaneous Electric Nerve Stimulation (TENS) machine in 30 smokers and 30 non-smokers. The subjects also underwent RDW evaluation. The data collected was analyzed using Pearson’s correlation coefficient. Results Fungiform papillae counts in smokers were less than those of non-smokers and an inverse relationship was detected between smoking and fungiform papillae count. Electrogustometric thresholds were more in smokers than non-smokers and showed direct relationship with smoking. RDW was significantly more in smokers compared to non-smokers. An inverse relationship was observed between fungiform papillae count and RDW. Conclusion Our results suggest that smokers have a high taste threshold because of decrease in the number of fungiform papillae on the tongue and RDW values do show an inverse relationship with fungiform papillae density which depicts subclinical nutritional deficiency bringing atrophic changes in tongue.

    In non-smokers, passive heat stress increases shear stress and vasodilation, decreasing arterial stiffness. Smokers, who reportedly have arterial dysfunction, may have similar improvements in arterial stiffness with passive heat stress. Therefore, we examined the effects of an acute bout of whole-body passive heat stress on arterial stiffness in smokers vs. non-smokers. Thirteen smokers (8.8 ± 5.5 [median = 6] cigarettes per day for >4 years) and 13 non-smokers matched for age, mass, height, and exercise habits (27 ± 8 years; 78.8 ± 15.4 kg; 177.6 ± 6.7 cm) were passively heated to 1.5 °C core temperature ( T C) increase. At baseline and each 0.5 °C T C increase, peripheral (pPWV) and central pulse wave velocity (cPWV) were measured via Doppler ultrasound. No differences existed between smokers and non-smokers for any variables (all p > 0.05), except cPWV slightly increased from baseline (526.7 ± 81.7 cm · s-1) to 1.5 °C Δ T C (579.7 ± 69.8 cm · s-1; p < 0.005), suggesting heat stress acutely increased central arterial stiffness. pPWV did not change with heating (grand mean: baseline = 691.9 ± 92.9 cm · s-1; 1.5 °C Δ T C = 691.9 ± 79.5 cm · s-1; p > 0.05). Changes in cPWV and pPWV during heating correlated ( p < 0.05) with baseline PWV in smokers (cPWV: r = -0.59; pPWV: r = -0.62) and non-smokers (cPWV: r = -0.45; pPWV: r = -0.77). Independent of smoking status, baseline stiffness appears to mediate the magnitude of heating-induced changes in arterial stiffness.

    Background Monitoring disparities in secondhand smoke (SHS) exposure is important for tailoring smoke-free policies to the needs of different groups. We examined disparity and trends in SHS exposure among both nonsmokers and smokers at Japanese workplaces between 2002 and 2012. Methods A total of 32,940 employees in nationally representative, population-based, repeated cross-sectional surveys in 2002, 2007 and 2012 in Japan was analyzed. Adjusted rate ratios for workplace SHS exposure from other people (“everyday” and “everyday or sometimes”) were calculated according to covariates, using log-binomial regression models with survey weights. In this survey, employees who do not smoke at workplace are defined as workplace-nonsmokers; and those smoke at workplace are used as workplace-smokers. SHS exposure for smokers does not involve their own SHS. Results While everyday SHS exposure prevalence in workplace-nonsmokers decreased markedly (33.2% to 11.4%), that in workplace-smokers decreased only slightly (63.3% to 55.6%). Workplace-smokers were significantly more likely to report everyday SHS exposure than workplace-nonsmokers, and the degree of association increased over time: compared with the nonsmokers (reference), covariates-adjusted rate ratio (95% confidence interval) for the smokers increased from 1.70 (1.62–1.77) in 2002 to 4.16 (3.79–4.56) in 2012. Similar results were observed for everyday or sometimes SHS exposure. Compared with complete workplace smoking bans, partial and no bans were consistently and significantly associated with high SHS exposure among both nonsmokers and smokers. We also observed disparities in SHS exposure by employee characteristics, such as age group and worksite scale. Conclusions Although overall SHS exposure decreased among Japanese employees between 2002 and 2012, the SHS exposure disparity between nonsmokers and smokers widened. Because smokers reported more frequent SHS exposure than nonsmokers, subsequent mortality

    Recently, genome-wide association studies have identified and validated genetic variations associated with urinary bladder cancer (UBC). However, it is still unknown whether the high-risk alleles of several SNPs interact with one another, leading to an even higher disease risk. Additionally, there is no information available on how the UBC risk due to these SNPs compare to the risk of cigarette smoking and to occupational exposure to urinary bladder carcinogens, and whether the same or different SNP combinations are relevant in smokers and non-smokers. To address these questions, we analyzed the genotypes of six SNPs, previously found to be associated with UBC, together with the GSTM1 deletion, in 1,595 UBC cases and 1,760 controls, stratified for smoking habits. We identified the strongest interactions of different orders and tested the stability of their effect by bootstrapping. We found that different SNP combinations were relevant in smokers and non-smokers. In smokers, polymorphisms involved in detoxification of cigarette smoke carcinogens were most relevant (GSTM1, rs11892031), in contrast to those in non-smokers with MYC and APOBEC3A near polymorphisms (rs9642880, rs1014971) being the most influential. Stable combinations of up to three high-risk alleles resulted in higher odds ratios (OR) than the individual SNPs, although the interaction effect was less than additive. The highest stable combination effects resulted in an OR of about 2.0, which is still lower than the ORs of cigarette smoking (here, current smokers' OR: 3.28) and comparable to occupational carcinogen exposure risks which, depending on the workplace, show mostly ORs up to 2.0.

    Background Smokers seeking treatment to quit smoking are generally not assessed for current depression, yet depression among smokers may influence quitting outcome. Purpose This study aims to formally assess current major depression among smokers calling a state tobacco quitline. Methods A total of 844 smokers calling the California Smokers’ Helpline in 2007 were screened for depression by the mood module of the Patient Health Questionnaire (PHQ-9). The Social Functioning Questionnaire (SFQ) was also administered to these callers. Two months after the screening, follow-up evaluations were conducted to assess cessation outcome. Results In all, 24.2% of smokers met criteria for current major depression and 16.5% reported symptoms indicating mild depression. Callers with current major depression were more likely to be heavy smokers and on Medicaid. Moreover, 74.0% of smokers with current major depression had substantial social and occupational functioning deficits. Two months later, those with major depression at baseline were significantly less likely to have quit smoking (18.5% vs 28.4%). Conclusions Almost one in four smokers to the California Smokers’ Helpline met criteria for current major depression. Over 400,000 smokers call state quitlines in the U.S. for help with quitting each year, which means that as many as 100,000 smokers with serious depressive symptoms are using these services annually. The large number of depressed smokers who seek help suggests a need to develop appropriate interventions to help them quit successfully. PMID:21146767

    Tobacco smoking is one of the most important risk factors for the development of oral mucosal lesions such as leukoplakia and hairy tongue. Controversy exists in the literature, however, about the prevalence of oral lesions in smokers. The aim of this study was to evaluate oral lesions in male smokers compared with nonsmokers in Hamadan. A total of 516 male participants were assessed, 258 of whom were smokers and 258 of whom were healthy nonsmokers. The prevalence of lesions was evaluated by clinical observation and biopsy. We found that the most prevalent lesions among smokers were gingival problems and coated tongue; smokers had significantly more lesions than did nonsmokers. Malignant and premalignant lesions were found in a higher age range. Among all participants in our study, we found a large number of oral mucosal lesions in smokers that had a strong correlation with smoking. Dental services need to implement care and health education for smokers to promote health. PMID:24010068

    The molecular biology revolution has turned the classification of life on its head. Is Whittaker's five-kingdom scheme for the classification of living things no longer relevant to life science education? Coupled with this is the discovery that most microscopic life cannot yet be brought into culture. One of the key organisms making this knowledge possible is Methanococcus jannishi a microorganism found in black smokers. This workshop presents the development of the Universal Tree of Life in a historical context and then links together major concepts in the New South Wales senior science programs of Earth and Environmental Science and Biology by examining the biological and geological aspects of changes to black smokers over geological time.

    Darcy's Law flow in a permeable medium, consisting of uniform parallel evenly spaced fractures, is used to elucidate how thermoelastic effects may modify the permeability and flow in fracture-controlled hydrothermal systems. Some simple permeability models are then used to investigate whether black smoker venting can result from focussing of low velocity porous flow into fractures at shallow depths ({approx equal} 100 m.). The models indicate that: (a) thermoelastic processes may be important in controlling the temporal evolution of hydrothermal upflow zones; (b) permeability structure, not just the bulk value of the permeability, may be critical for the formation of black smokers; (c) a small zone extending to a depth of {approx equal} 100 m containing a few fractures a factor of 2 or more wider than average may be sufficient to focus upflow into discrete vents provided thermoelastic and chemical effects seal parts of the upper crust.

    The comet assay has been widely used to quantify DNA damage in isolated lymphocytes from subjects exposed to several environmental or occupational substances, especially for estimation of oxidative damage in the DNA, which is well-known to be induced by tobacco smoke. Passive smoking or environmental tobacco smoke (ETS) has been included among those substances that cause cancer with sufficient evidence in humans. In this study, we analyzed, by the alkaline version of comet assay, the lymphocyte DNA damage of white-collar active smokers and non- and ex-smokers exposed to ETS at the workplace. We investigated basal DNA damage, DNA oxidation by formamidopyrimidine glycosylase (Fpg), the repair capacity H2O2-induced DNA damage by kinetics studies and lymphocyte GSH levels, the major intracellular defense against exogenous oxidative stress imposed by cigarette smoking. Our results indicated high basal DNA damage with clear significant correlations with urinary nicotine and cotinine, number of cigarettes/day, and an inverse significant correlation with GSH cellular content in active smokers. Significant Fpg-sensitive sites were found in smokers (> 85%), considerably high but not significant in passive non- and ex-smokers (> 51% and 37%, respectively). The DNA repair capacity had seriously decreased in non-smokers > smokers > ex-smokers, while the same damage was repaired in a short time in never smokers. PMID:17027201

    Objectives. We examined the relationship between cigarette excise tax increases and tax-avoidant purchasing behaviors among New York City adult smokers. Methods. We analyzed data from the city’s annual Community Health Survey to assess changes in rates of tax avoidance over time (2003–2010) and smokers’ responses to the 2008 state cigarette tax increase. Multivariable logistic regression analysis identified correlates of buying more cigarettes on the street in response to the increase. Results. After the 2002 tax increase, the percentage of smokers engaged in tax-avoidant behavior decreased with time from 30% in 2003 to 13% in 2007. Following the 2008 tax increase, 21% of smokers reported buying more cigarettes from another person on the street. Low-income, younger, Black, and Hispanic smokers were more likely than respondents with other sociodemographic characteristics to purchase more cigarettes on the street. Conclusions. To maximize public health impact, cigarette tax increases should be paired with efforts to limit the flow of untaxed cigarettes entering jurisdictions with high cigarette pack prices. PMID:23597382

    Introduction: Blacks suffer disproportionately from the long-term health effects of smoking. Little is known about the prevalence of the early health consequences of smoking in this population or whether psychosocial factors influence the frequency of symptoms. This study investigated the prevalence and psychosocial correlates of smoking-related physical symptoms in Black smokers. Methods: Adult smokers (N = 117, 58% female, Mage = 43.0 years) who smoked at least 5 cigarettes/day completed self-administered assessments of cigarettes smoked per day, smoking duration, alcohol use, perceived stress, depressive symptoms, and smoking-related symptoms. Results: The most frequently occurring physical symptoms were shortness of breath (66%), coughing (50%), and headaches (49%). Multivariate analyses showed that smoking history, alcohol use, perceived stress, and depressive symptoms were independently related to smoking-related symptoms, even after controlling for sociodemographic variables and medical diagnoses. Discussion: The early health consequences of smoking appear to be common among Black smokers and can serve as a cue to action for cessation efforts. Alcohol use, stress, and depression appear to negatively influence the early health consequences of smoking and should be assessed routinely in treatment-seeking Black smokers. PMID:19359391

    HIV-positive populations have high smoking rates and smoking puts HIV-positive individuals at higher risk for HIV-related health problems. Little information is available on the characteristics of HIV-positive smokers. The present study examines the baseline psychosocial characteristics of 184 HIV-positive cigarette smokers enrolled in a smoking cessation clinical trial. The sample was 82% male, and 53% Caucasian. Over half were unemployed and 43.8% reported an income of less than $10,000. Mean cigarettes per day was 19.2 and the mean Fagerström Test Nicotine Dependence score was 4.8. The majority reported a strong desire to quit however, only 45% endorsed a goal of complete abstinence. On average, 43.2% of the smokers' social support was made up of other smokers. Both licit and illicit drug use was common and there were significant rates of lifetime psychiatric diagnoses in this cohort of smokers. It is critical to evaluate interventions that consider the specific needs of this group. PMID:19537954

    Background: Because cigarette smoke is a powerful ROS producer, we hypothesized that the spermatozoa of smokers would be more at risk of having increased DNA fragmentation than spermatozoa of non-smoking men. Methods: A Cross-Sectional Study was performed on consenting smokers and non-smokers, consulting in an infertility clinic for routine sperm analysis. The application of a novel TUNEL assay coupled to a vitality marker, LIVE/DEAD®, allowed both DNA fragmentation and viability measurement within spermatozoa of participants to be analyzed by flow cytometry. Results: The coupled vitality-DNA fragmentation analysis revealed that non-smokers and smokers respectively presented medians of 3.6% [0.6-36.8] and 3.3% [0.9-9.6] DNA fragmented spermatozoa among the living spermatozoa population (p>0.05). Conclusion: No deleterious effect of smoking on spermatozoa was found in our study. More studies concerning potential mutagenic capacities of cigarette smoke on spermatozoa are necessary. In addition, the coupled vitality-DNA fragmentation analysis may orient Assisted Reproductive Technologies teams when confronted with patients having a high percentage of DNA-fragmented living spermatozoa. © 2014 Clinical Cytometry Society.

    Early detection of cells carrying somatic mutations at oncogenic loci could prove useful for identifying individuals at high risk for cancer and permit intervention prior to the onset of clinically recognizable disease. We have determined the frequency of rare t(14;18)(q32;q21) translocations at the bcl-2 proto-oncogene locus in the peripheral blood of 85 smokers and 35 nonsmokers using a sensitive nested PCR assay. The identical translocation occurs in 85% of follicular lymphoma tumors, and about 50% of all non-Hodgkin`s Lymphoma. Smokers with the highest exposure had a 3.6-fold higher mutation frequency relative to the nonsmokers. Logistic regression analysis showed that of the variables tested (age, race, sex, current smoking, years of smoking, and pack-years), the cumulative smoking measure (pack-years) was the best predictor of t(14;18) frequency (p=0.004). These observations are consistent with two recent epidemiological studies showing 2.3-fold and 3.8-fold increased risk for Non-Hodgkins lymphoma among heavy smokers. The results support the hypothesis that smokers have an increased burden of lymphocytes bearing bcl-2 mutations which raises their individual risk for future lymphoid tumors. We speculate that the increased frequency of oncogenic translocations in smokers may result either from the mutagenic or antigenic activity of cigarette smoke.

    Inhalation exposure to particulates such as cigarette smoke and coal dust is known to contribute to the development of chronic lung disease. The purpose of this study was to estimate the amount of elemental carbon (EC) deposits from autopsied lung samples from cigarette smokers, miners, and control subjects and explore the relationship between EC level, exposure history, and the extent of chronic lung disease. The samples comprised three subgroups representing never smokers (8), chronic cigarette smokers (26), and coal miners (6). Following the dissolution of lung tissue, the extracted EC residue was quantified using a thermal-optical transmission (TOT) carbon analyzer. Mean EC levels in the lungs of the control group were 56.68 ± 24.86 (SD) μg/g dry lung weight. Respective mean EC values in lung samples from the smokers and coal miners were 449.56 ± 320.3 μg/g and 6678.2 ± 6162 μg/g. These values were significantly higher than those obtained from the never-smoker group. EC levels in the lung and pack-years of cigarette smoking correlated significantly, as did EC levels and the severity of small airway disease. This study provides one of the first quantitative assessments of EC in human lungs from populations at high relative risk for the development of chronic lung disease.

    Addiction to tobacco-derived nicotine remains highly prevalent in the US, with 18% using daily, but 53% of those with serious mental illness smoke regularly. While smokers with serious mental illness have been excluded from most large nicotine dependence treatment studies, a growing evidence base is emerging to guide clinicians in how to assist their patients with psychiatric illness to quit smoking. The aim of this review is to present the evidence on safety and efficacy of smoking cessation interventions for those with serious mental illness. Smokers with schizophrenia spectrum disorders should receive varenicline or bupropion with or without nicotine replacement therapy (NRT) in combination with behavioral treatment. Preliminary evidence suggests that varenicline in combination with behavioral support is efficacious and well tolerated for smoking cessation for those with bipolar disorder and major depressive disorder. More work is needed to establish treatment guidelines for smokers with major depressive disorder and bipolar disorder. Controlled trials to date have not found evidence for worsening of psychiatric symptoms or increased rate of psychiatric adverse events in this population with available pharmacotherapeutic cessation aids. Converging evidence indicates that a majority of smokers with serious mental illness want to quit smoking and that available pharmacotherapeutic cessation aids combined with behavioral support are both effective for and well tolerated by these smokers. Most people with serious mental illness see their psychiatrist more regularly than their primary care physician, and many receive care exclusively in a psychiatric treatment setting. Psychiatrists thus have an important role to play in the recognition and treatment of tobacco use disorders in people with serious mental illness. PMID:25747922

  1. Changes in the profiles of smokers seeking cessation treatment and in its effectiveness in Galicia (Spain) 2001–10

    Background In recent years, the prevalence of daily smokers has decreased in all developed countries due to a great variety of factors. Despite this decrease, the effectiveness of clinical treatments has decreased and several studies report a change in smokers’ characteristics. The purpose of the present study is to analyze the changes in the characteristics of Spanish smokers who seek smoking cessation treatment between 2001 and 2010 and the changes in the effectiveness of such treatment. Methods The sample was made up of 870 smokers who sought psychological treatment for giving up smoking at the Smoking Cessation Unit in the Faculty of Psychology of the University of Santiago de Compostela (Spain) during the period 2001 to 2010. Results Smokers in the 2006–2010 group, compared to those in the 2001–2005 group, were older, smoked fewer cigarettes per day and of a brand with fewer mg/nicotine, had been smoking longer, were less motivated to give up smoking, and had more antecedents of depression. Quit rates were validated by testing smokers' carbon monoxide (CO) levels. Percentages of abstinence were higher in the 2001–2005 group than in the 2006–2010 group (58.7% vs. 52.15 at the end of treatment, p = 0.05); 30.8% vs. 24.2% at 6 months follow-up, p = 0.031; 27.5% vs. 22% at 12 months follow-up, p = 0.059). Although abstinence decreased more than 5% in the 2006–2010 group there were no differences between the two groups in nicotine dependence. Those participants who did not assist to the follow-up were considered smokers at pretreatment level. Conclusions In Spain there has been a qualitative change in the profile of the smokers seeking smoking cessation treatment. Treatment effectiveness has decreased, and the variables predicting intervention outcome have changed. PMID:24938635

    Background Electronic cigarettes (e-cigarettes) are being increasingly used. We examined the correlates associated with e-cigarette awareness, use and perceived effectiveness in smoking cessation among Chinese daily smokers in Hong Kong. Methods Daily smokers (N = 1,307) were recruited to a community-based randomised controlled trial (‘Quit to Win’) in 2014. Socio-demographic characteristics, conventional cigarette smoking status, nicotine addiction level, quit attempts, quit intention, e-cigarette awareness, use and perceived effectiveness on quitting were reported at baseline and 1-week follow-up. Multivariate logistic regression was used to identify factors associated with e-cigarette awareness, use and perceived effectiveness in quitting. Results Most smokers (82.6%, 95% CI 80.2%-84.9%) had heard about e-cigarettes, and 13.3% (11.3%-15.5%) ever used e-cigarettes. Most users (74.1%) and non-users (91.2%) did not perceive e-cigarettes as effective in quitting. Being younger and having a larger family income were associated with e-cigarette awareness. Being younger, a tertiary education and a stronger addiction to nicotine were associated with e-cigarette use, which was itself associated with lower levels of intention to quit and had no association with attempts to quit (P for trend 0.45). E-cigarette use, the last quit attempt being a month earlier, having made a quit attempt lasting 24 hours or longer and perceiving quitting as important were all associated with the perceived effectiveness of e-cigarettes in quitting (all P <0.05). Conclusions Among community-recruited smokers who intended to quit, awareness of e-cigarettes was high, but most did not perceive e-cigarettes as effective in quitting. Correlates concerning e-cigarette perceptions and use will help to inform prospective studies, public education and policy on controlling e-cigarettes. PMID:26502284

    ABSTRACT Humans are exposed daily to di(2-ethylhexyl) phthalate (DEHP), a plasticizer found in many consumer, medical, and building products containing polyvinyl chloride. Large doses of DEHP disrupt normal ovarian function; however, the effects of DEHP at environmentally relevant levels, the effects of DEHP on folliculogenesis, and the mechanisms by which DEHP disrupts ovarian function are unclear. The present study tested the hypothesis that relatively low levels of DEHP disrupt estrous cyclicity as well as accelerate primordial follicle recruitment by dysregulating phosphatidylinositol 3-kinase (PI3K) signaling. Adult CD-1 mice were orally dosed with DEHP (20 μg/kg/day–750 mg/kg/day) daily for 10 and 30 days. Following dosing, the effects on estrous cyclicity were examined, and follicle numbers were histologically quantified. Further, the ovarian mRNA and protein levels of PI3K signaling factors that are associated with early folliculogenesis were quantified. The data indicate that 10- and 30-day exposure to DEHP prolonged the duration of estrus and accelerated primordial follicle recruitment. Specifically, DEHP exposure decreased the percentage of primordial follicles and increased the percentage of primary follicles counted following 10-day exposure and increased the percentage of primary follicles counted following 30-day exposure. DEHP exposure, at doses that accelerate folliculogenesis, increased the levels of 3-phosphoinositide-dependent protein kinase-1, mammalian target of rapamycin complex 1, and protein kinase B and decreased the levels of phosphatase and tensin homolog, potentially driving PI3K signaling. Collectively, relatively low levels of DEHP disrupt estrous cyclicity and accelerate primordial follicle recruitment potentially via a mechanism involving dysregulation of PI3K signaling.

  4. Long-term maintenance combination chemotherapy with OPEC/MPEC (vincristine or methotrexate, prednisolone, etoposide and cyclophosphamide) or with daily oral etoposide and prednisolone can improve survival and quality of life in adult T-cell leukemia/lymphoma.

    Acute leukemia and lymphoma varieties of adult T-cell leukemia/lymphoma (ATL) usually carry a poor prognosis. While etoposide is generally useful for treating ATL, especially as a daily oral maintenance regimen, etoposide has not proven effective in severe types of ATL efficient in some patients. Of 87 ATL patients whom we have treated, 51 had acute leukemia, 22 lymphoma and 14 progressive chronic leukemia. Seventy-nine patients were treated with a long term maintenance combination protocol, OPEC/MPEC (weekly doses of vincristine, 0.7 mg/m2 or methotrexate, 14 mg/m2; prednisolone, 20 mg/m2; etoposide, 70 mg/m2 and cyclophosphamide, 200 mg/m2). The other 8 patients, 3 with acute leukemia, 2 with lymphoma and 3 with progressive chronic leukemia, were treated with daily oral administration of 25 mg of etoposide and 10 mg of prednisolone (DOEP). The dose administered was modified in individual cases to maintain the granulocyte count and reduce the number of ATL cells. Considering both protocols, a complete response and a partial response were achieved in 31.0% and 58.6% patients, respectively. Median survival times (MST) of all patients and, acute leukemia, lymphoma and progressive chronic leukemia types were 7.5, 6.7, 9.6 and 12.4 months, respectively. Respective MST of patients treated with OPEC/MPEC or DOEP protocols were 7.1 and 18.0 months. Relatively normal WBC counts, lower lactate dehydrogenase concentration and normal calcium concentration, limited numbers of anatomic sites involved, good performance status and good response to chemotherapy were significantly associated with long survival time. Drug toxicity was not apparent, and about half of patients were treated in an outpatient setting. PMID:10613451

    Background Physicians do not routinely recommend smokers to undergo spirometry unless they are symptomatic. Objective To test the hypothesis that there are a significant number of asymptomatic smokers with chronic obstructive pulmonary disease (COPD), we estimated the prevalence of COPD in a group of asymptomatic smokers. Methods Two thousand nine hundred and sixty-one smokers with a cumulative consumption history of at least 10 pack-years, either smokers with symptoms or smokers without symptoms (WOS) were invited to perform a spirometry and complete a symptom questionnaire. Results Six hundred and thirty-seven (21.5%) smokers had no symptoms, whereas 2,324 (78.5%) had at least one symptom. The prevalence of COPD in subjects WOS was 1.5% when considering the whole group of smokers (45/2,961) and 7% when considering only the group WOS (45/637). From 329 smokers with COPD, 13.7% were WOS. Subjects WOS were younger, had better lung function and lower cumulative consumption of cigarettes, estimated as both cigarettes per day and pack-years. According to severity of airflow limitation, 69% vs 87% of subjects were classified as Global Initiative for Chronic Obstructive Lung Disease stages I–II in the WOS and smokers with symptoms groups, respectively (P<0.001). A multivariate analysis showed that forced expiratory volume in 1 second (mL) was the only predictive factor for COPD in asymptomatic smokers. Conclusion Prevalence of COPD in asymptomatic smokers is 1.5%. This number of asymptomatic smokers may be excluded from the benefit of an “early” intervention, not just pharmacological but also from smoking cessation counseling. The higher forced expiratory volume in 1 second may contribute to prevent early diagnosis. PMID:26586941

  7. Craving, Cue Reactivity, and Stimulus Control Among Early-Stage Young Smokers: Effects of Smoking Intensity and Gender

    PubMed Central

    Introduction: Smoking initiation usually begins in adolescence, but how and for whom nicotine dependence emerges during this period is unclear. The cue-reactivity paradigm is well suited to examine one marker of dependence: craving-related stimulus control, i.e., the ability of environmental cues to elicit craving to smoke. This study examined the effects of both level of smoking involvement (daily vs. occasional smoking) and gender on reactivity to both smoking and alcohol cues. Methods: Young (age range 16–20; 42% female) daily (n = 55) and occasional (n = 52) smokers were exposed to each of three counterbalanced cues: (a) in vivo smoking (e.g., sight, smell, lighting of cigarette), (b) alcohol (e.g., opening, pouring, and smell of preferred beverage), and (c) neutral cue. Results: Daily smokers exhibited higher levels of tonic (i.e., noncue-elicited) craving than did occasional smokers. Both groups showed significant increases in craving in response to cues (i.e., cue-elicited craving), with little evidence that cue-elicited craving differed between groups. Females were more cue reactive to both the alcohol and smoking cues than males, particularly for the positively reinforced aspects of smoking (i.e., hedonic craving). There were no gender × group interaction effects in response to either the alcohol or the smoking cue. Conclusions: Findings show the presence of cue-elicited craving even among occasional smokers and are consistent with literature demonstrating heightened sensitivity to environmental cues among females. Cue-elicited craving may be one mechanism that contributes to the maintenance of smoking behavior and perhaps to the development of nicotine dependence within early stage smokers. PMID:24042699

    This study examined the feasibility, acceptability, and outcomes of a culturally tailored smoking cessation intervention for HIV-positive African American male smokers. Eligible smokers were enrolled in a seven-session group-based treatment combined with nicotine patch. The mean age of participants was M=46 years. The majority were daily smokers (71%), smoked a mentholated brand (80%), and averaged 8.6 (standard deviation [SD]=8.1) cigarettes per day. Baseline nicotine dependency scores (M=5.8) indicated a moderate to high degree of physical dependence. Of the 31 participants enrolled, the majority completed treatment (≥3 sessions; 68%), 1-month follow-up (74%), and 3-month follow-up (87%) interviews. Program acceptability scores were strong. However, adherence to the patch was low, with 39% reporting daily patch use. The majority of participants (80%, n=24) made a quit attempt. Furthermore, over the course of the intervention, smoking urge, cigarettes smoked, nicotine dependence, withdrawal symptoms, and depression scores all significantly decreased. Follow-up quit rates at 1 and 3 months ranged from 6% to 24%, with treatment completers having better outcomes. This first of its kind intervention for HIV-positive African American male smokers was feasible, acceptable, and showed benefit for reducing smoking behaviors and depression scores. Smoking cessation outcomes were on par with other similar programs. A larger trial is needed to address limitations and to confirm benefits.

    Fixed-dose nicotine replacement therapy (NRT) is efficacious for smoking cessation in the general population of smokers. However, it is less effective in populations with psychiatric comorbidities and/or severe tobacco dependence where the percent nicotine replacement is suboptimal. The objective of this pilot study was to determine the effectiveness of nicotine patch dose titration in response to continued smoking in heavily dependent smokers with psychiatric comorbidity. In a single-arm, open-label study adult smokers (mean cigarettes per day, 25.4 ± 13.4; range, 14-43; n = 12) willing to quit were treated with escalating doses of transdermal nicotine and brief counseling intervention if they continued to smoke over a 9-week treatment period. Plasma nicotine and cotinine, along with expired carbon monoxide levels, and the subjective effects of smoking, urge to smoke, demand elasticity, and mood symptoms were also assessed. The mean NRT dose was 32.7 (SD, 16.4) mg/d (range, 7-56 mg/d). Smokers reported significant reductions in both cigarettes per day (mean decrease, 18.4 ± 11.5) confirmed by expired carbon monoxide (mean decrease, 13.5 ± 13.0) with no significant changes in plasma nicotine concentrations during the course of NRT dose titration. There were significant effects on the subjective effects of smoking and measures of smoking behavior. Most commonly reported adverse events were respiratory infections, skin irritation at patch site, nausea, and sleep disturbances, which were generally mild and transient. Titrating doses of NRT to effect with brief intervention hold promise as an effective clinical strategy to assist heavily dependent psychiatrically ill smokers to change their smoking behavior.
