[Ti] Título:Executive function fails to predict smoking outcomes in a clinical trial to motivate smokers to quit.

[Ab] Resumo:BACKGROUND: Executive function (EF) is considered an important mediator of health outcomes. It is hypothesized that those with better EF are more likely to succeed in turning their intentions into actual health behaviors. Prior studies indicate EF is associated with smoking cessation. Experimental and longitudinal studies, however, have yielded mixed results. Few studies have examined whether EF predicts post-treatment smoking behavior. Fewer still have done so prospectively in a large trial. We sought to determine if EF predicts quit attempts and cessation among community smokers in a large randomized trial evaluating the efficacy of motivational interventions for encouraging cessation. METHODS: Participants (N=255) completed a baseline assessment that included a cognitive battery to assess EF (Oral Trail Making Test B, Stroop, Controlled Oral Word Association Test). Participants were then randomized to 4 sessions of Motivational Interviewing or Health Education or one session of Brief Advice to quit. Quit attempts and cessation were assessed at weeks 12 and 26. RESULTS: In regression analyses, none of the EF measures were statistically significant predictors of quit attempts or cessation (all ps>0.20). CONCLUSIONS: Our data did not support models of health behavior that emphasize EF as a mediator of health outcomes. Methodological shortcomings weaken the existing support for an association between EF and smoking behavior. We suggest methodological improvements that could help move this potentially important area of research forward.

[Ti] Título:Melatonin reverses the enhanced oxidative damage to membrane lipids and improves skin biophysical characteristics in former-smokers - A study in postmenopausal women.

[Ab] Resumo:INTRODUCTION AND OBJECTIVE: Protective antioxidative effects of melatonin have been repeatedly documented in experimental and clinical studies. One of the most spectacular exogenous prooxidative agents is cigarette smoking. The aim of the study was to evaluate the level of oxidative damage to membrane lipids (lipid peroxidation; LPO) in blood serum, and in epidermis exfoliated during microdermabrasion collected from former-smokers who were treated with melatonin. MATERIAL AND METHODS: The study was performed in postmenopausal women. Ninety (90) female volunteers, aged 46-67 years, were enrolled. Two major groups, i.e. never-smokers (n=44) and former-smokers (n=46), were divided into: Control, melatonin topical skin application, Restructurer (containing antioxidants) topical skin application, and melatonin oral treatment. Microdermabrasion was performed at point '0', after 2 weeks, and after 4 weeks of treatment. The following parameters were measured: LPO in blood serum, LPO in epidermis exfoliated during microdermabrasion, and skin biophysical characteristics, such as sebum, moisture, elasticity, and pigmentation. Malondialdehyde+4-hydroxyalkenals level (LPO index) was measured spectrophotometrically. RESULTS: Melatonin oral treatment significantly reversed the increased serum LPO level in former-smokers already after 2 weeks of treatment. In a univariate regression model, LPO blood level constituted the only independent factor negatively associated with melatonin oral treatment. After 4 weeks of treatment, melatonin given orally increased skin sebum, moisture and elasticity levels, and melatonin applied topically increased sebum level. CONCLUSIONS: Exogenous melatonin reverses the enhanced oxidative damage to membrane lipids and improves skin biophysical characteristics in former-smokers.

[Ti] Título:Conditional Effects of Gain-Loss-Framed Narratives among Current Smokers at Different Stages of Change.

[Ab] Resumo:This study examines how current smokers respond differently to gain-loss-framed antismoking narratives depending on their stages of change to quit smoking. An experiment (N = 461) was conducted with a 2 (narrative perspective: first person vs. third person) × 2 (framing: gain vs. loss) factorial design having smoker's stage of change (precontemplation vs. contemplation/preparation) as a moderator. We observed differential framing effects depending on smoker's current stages of change only when they were exposed to first-person narratives. For precontemplators, a loss-framed (vs. a gain-framed) first-person narrative induced greater quit intentions and stage progression. Conversely, among contemplators and preparers, a gain-framed (vs. a loss-framed) first-person narrative led to greater quit intentions and stage progression. These interactive patterns were partly mediated by self-referencing and perceived similarity. This study proposes an alternative mechanism to explain the conditional framing effect by stages of change and highlights the importance of tailoring messages to smoker's psychosocial characteristics and needs.
