Increasing smoking cessation adherence: Do we need to consider the role of executive function and rumination?
Despite the cost and health consequences, a large number of people continue to smoke cigarettes worldwide every day. Notwithstanding, there have been a number of interventions to help people stop smoking but, in general, these have produced only limited success, and better interventions are needed. Accruing evidence affirmed that rumination and executive function play a pivotal role in cigarette smoking behavior, and in this editorial, we describe and discuss the key findings between these constructs and smoking, and argue that an impairment in executive functions does not act alone, but interacts with rumination by directing attention to depressive thoughts, thereby reducing the ability of smokers to engage in constructive behaviors, such as quitting smoking. Finally, we offer a new theory-driven model based on a deep understanding of the interactions between executive functions and rumination and potential moderator effects

The Effectiveness of the Mitchell Method Relaxation Technique for the Treatment of Fibromyalgia Symptoms: A Three-Arm Randomized Controlled Trial
Objective: To evaluate the effectiveness of the Mitchell Method Relaxation Technique (MMRT) in reducing symptoms of fibromyalgia. Design: A randomised controlled trial was used to compare the effectiveness of self-administered MMRT (n= 67) with attention control (n = 66) and usual care (n = 56) groups. Main Outcome Measures: Primary outcomes included self-reported fatigue, pain, and sleep. Secondary outcomes were daily functioning, quality of life, depression, and coping, anxiety and perceived stress. Outcomes were assessed at baseline, post-intervention (four weeks) and followup (eight weeks). Results: A significant combined improvement on outcomes (p<.005), specific significant effects for sleep problems (d=0.29, p<.05), sleep inadequacy (d=0.20, p<.05), and fatigue (d=0.47, p<.05) were present in the MMRT group. At the follow-up, fatigue did not differ to the post-intervention score (p=.25) indicating short-term sustainability of the effect. The effects on sleep problems and sleep inadequacy were not sustained. The pain levels decreased when the MMRT was practiced three times a week (p<.001). Conclusion: MMRT was effective in reducing pain, sleep problems, and fatigue. High rates of relative risk reduction for fatigue (37%) and pain (42.8%) suggest clinical significance
Psychosocial work characteristics, need for recovery and musculoskeletal problems predict psychological distress in a sample of British workers.
From an original sample of 2454 participants free of self-reported psychological distress, 1463 workers completed a 15-month follow-up. Baseline measures included exposure to job demands, decision latitude, social support and need for recovery. Psychological distress was assessed using the General Health Questionnaire at baseline and at follow-up. The findings showed that medium and high exposure to job demands and social support increased the risk of reporting psychological distress at 15-months (relative risk (RR)Â =Â 1.65, 1.45). The highest adjusted RR was observed for workers reporting a high need for recovery after work (RR 2.12, 1.90) and this finding was independent of the effects of job demands, decision latitude and social support. Neither decision latitude, nor low back problems increased the risk of reporting future psychological distress, although neck problems (RRÂ =Â 1.66) and hand/wrist problems (RRÂ =Â 1.45) did. It was concluded that need for recovery appears to be an important indicator of individual workers who are at risk of developing psychological distress long term. Statement of Relevance: This paper reports the findings of a longitudinal study showing that need for recovery from work was the strongest predictor, relative to psychosocial work characteristics (job demands, decision latitude and social support), and musculoskeletal problems, of psychological distress 15 months later in individuals initially free from distress
Acute exercise effects on smoking withdrawal symptoms and desire to smoke are not related to expectation
Assessing the effect of a Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination, fatigue, and sleep
This quasi-experimental longitudinal study assessed the effect of a one-day Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination, chronic fatigue and sleep quality. We hypothesised that participants who attended the workshop would report lower levels of affective work-related rumination and chronic fatigue and improved sleep quality, at follow-up, six months after workshop completion. Two hundred and twenty seven participants took part in the study, with 102 participants attending a one-day workshop delivered in their place of work. Participants completed an online questionnaire at two time-points, with follow-up occurring 6 months after initial survey completion. Results showed that participants who took part in the CBT workshop reported significantly lower levels of affective rumination (p=.03) and chronic fatigue (p=.003), at follow-up in comparison to individuals who did not attend the workshop; however there were no significant differences between the groups in self-reported sleep quality (p=.06). A combination of more effective recovery both at work and outside of work may explain the reductions in both affective rumination and fatigue over time. This study adds to the recovery from work literature by providing initial support for a one-day CBT-based workshop delivered in the workplace
Short Bouts of Physical Activity Are Associated with Reduced Smoking Withdrawal Symptoms, but Perceptions of Intensity May Be the Key.
The primary aim of this study was to assess the effectiveness of a short bout (10 min) of moderate-intensity exercise to reduce withdrawal symptomatology, craving and negative affect; while the secondary aim was to assess how the effectiveness of a short bout of moderate exercise can be modulated by the perception of intensity in physically active and low-activity smokers. Fifty low-activity and physically active smokers were recruited (24 male and 26 female) and randomized in three different conditions. Prescribed (objective) moderate intensity (OBJ) and perceived moderate intensity (PER), and passive waiting (PW). After the intervention (T3), smokers reported less desire to smoke in the PER (p < 0.001) and OBJ (p < 0.001) conditions, relative to the PW condition. At T3 smokers in the PER condition reported less negative affect than smokers in the PW condition relative to the baseline (T1) (p < 0.007). Further, smokers in the PER condition reported less negative affect than smokers in the PW condition (p < 0.048). Physically active (PA) smokers perceived less exertion than low-activity (LA) smokers, and the effects were stronger in the PER condition relative to OBJ. Generally, our results suggest that a short bout of moderate exercise helps both LA and PA smokers. These findings provided a novel insight into the psychological mechanisms that affect the efficacy of the exercise in smoking cessation and suggest that exercise should be tailored according to individual perception of intensity
A Sustained Dietary Change Increases Epigenetic Variation in Isogenic Mice
Epigenetic changes can be induced by adverse environmental exposures, such as nutritional imbalance, but little is known about the nature or extent of these changes. Here we have explored the epigenomic effects of a sustained nutritional change, excess dietary methyl donors, by assessing genomic CpG methylation patterns in isogenic mice exposed for one or six generations. We find stochastic variation in methylation levels at many loci; exposure to methyl donors increases the magnitude of this variation and the number of variable loci. Several gene ontology categories are significantly overrepresented in genes proximal to these methylation-variable loci, suggesting that certain pathways are susceptible to environmental influence on their epigenetic states. Long-term exposure to the diet (six generations) results in a larger number of loci exhibiting epigenetic variability, suggesting that some of the induced changes are heritable. This finding presents the possibility that epigenetic variation within populations can be induced by environmental change, providing a vehicle for disease predisposition and possibly a substrate for natural selection.This work was supported by the Australian Research Council (DP0771859) and the National Health and Medical Research Council (#459412, #635510)
The Association Between Work-Related Rumination and Executive Function Using the Behavior Rating Inventory of Executive Function
This is the final version. Available on open access from Frontiers Media via the DOI in this recordData Availability Statement:
The datasets generated for this study are available on request to the corresponding author.Work-related rumination has been associated with a number of health complaints, however, little is known about the underlying factors associated with rumination. Previous work using proxy measures of executive function showed work-related rumination to be negatively associated with executive function. In this paper, we report two studies that examined the association between work-related rumination and executive function utilizing an ecological valid measure of executive function: the Behavior Rating Inventory of Executive Function (BRIEF-A, Roth et al., 2005). In study 1 (N = 63), high, relative to low work-related ruminators, were found to demonstrate lower executive function skills, in eight of the nine subscales of the BRIEF. The aim of study 2 (N = 237) was to identify, the key executive function subscale/s associated with work-related rumination. Controlling for known factors associated with work-related rumination (fatigue and sleep), regression analysis identified the behavioral regulation subscale "shift" as the key predictor within the model. Shift relates to our ability to switch attention, to think about different solutions, and dealing with and accepting change. It was concluded that these findings lend support for future research to develop interventions for enhancing shift ability, as an aid to reduce work-related ruminative thinking
An association between pulmonary Mycobacterium avium-intracellulare complex infections and biomarkers of Th2-type inflammation
Background: The rising incidence of pulmonary Mycobacterium avium-intracellulare complex (MAI) infection is unexplained but parallels the growing world-wide epidemic of allergic disease. We hypothesized an association between pulmonary MAI infection and Th2-type immune responses as seen in allergy. / Methods: Biomarkers of patient Th2-type immune responses (peripheral blood eosinophil counts and serum IgE levels) were compared between patients with positive pulmonary samples for tuberculosis and non-tuberculous mycobacterial (NTM) infection. A further comparison of clinical characteristics, including respiratory co-morbidities, and biomarkers, was conducted between patients culturing MAI NTM and those culturing NTM other than MAI. / Results: Patients culturing NTM from pulmonary samples had significantly higher peripheral blood eosinophil levels than those culturing Mycobacterium tuberculosis. Furthermore, patients culturing MAI compared to those culturing NTM other than MAI had higher eosinophil counts (mean 0.29x109/L vs 0.15x109/L, p=0.010) and IgE levels (geometric mean 138kU/L vs 47kU/L, p=0.021). However there was no significant difference in the frequency of asthma between the two NTM groups. / Conclusions: There is an association between biomarkers of Th2-type immune responses and pulmonary MAI. Prospective and translational research could identify the direction of causation; and so determine whether our finding may be utilized within future management strategies for MAI
The association between work-related rumination and heart rate variability: A field study
This is the final version. Available on open access from Frontiers Media via the DOI in this recordThe objective of this study was to examine the association between perseverative cognition in the form of work-related rumination, and heart rate variability (HRV). We tested the hypothesis that high ruminators would show lower vagally mediated HRV relative to low ruminators during their leisure time. Individuals were classified as being low (n = 17) or high ruminators (n = 19), using the affective scale on the work-related rumination measure. HRV was assessed using a wrist sensor band (Microsoft Band 2). HRV was sampled between 8 pm and 10 pm over three workday evenings (Monday to Wednesday) while individuals carried out their normal evening routines. Compared to the low ruminators, high affective ruminators demonstrated lower HRV in the form of root mean square successive differences (RMSSDs), relative to the low ruminators, indicating lower parasympathetic activity. There was no significant difference in heart rate, or activity levels between the two groups during the recording periods. The current findings of this study may have implications for the design and delivery of interventions to help individuals unwind post work and to manage stress more effectively. Limitations and implications for future research are discussed
