Effect of 5-HT 2C receptor agonist and antagonist on chronic unpredictable stress (CUS) - Mediated anxiety and depression in adolescent Wistar albino rat: Implicating serotonin and mitochondrial ETC-I function in serotonergic neurotransmission. Behav Brain Res 2020; 393:112780. [PMID: 32579979 DOI: 10.1016/j.bbr.2020.112780] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 06/15/2020] [Accepted: 06/17/2020] [Indexed: 12/30/2022]
Abstract
Anxiety and depression are among the major neuropsychiatric disorders worldwide, and yet the etiologies of these disorders remain unclear to date. Chronic unpredictable stress (CUS) procedure mimics several behavioral characteristics such as anxiety and depression in rodents. Using this animal model, we have attempted to understand the serotonergic system in the hippocampus and prefrontal cortex, while using the 5-HT2CR agonist and antagonist in evaluating 5-HT2C receptor neurotransmission. A decrease in serotonin (5-HT) level, tryptophan hydroxylase-2 activity and, 5-HT2CR receptor protein down-regulation in the CUS exposed group, explains the involvement of 5-HT and 5-HT2CR neurotransmission in the genesis of anxiety and depression. Besides, the oxidative stress - attenuated electrolyte imbalance via decrease ATPase pump activity, and compromised oxidative phosphorylation via decrease ETC-I activity are some of the underlying factors affecting neuronal cell survival and serotonergic neurotransmission. To complement our finding, altered behavioral performance scored in the open field test, elevated plus maze test, and the forced swim test, when exposed to CUS is indicative or consistent with anxiety, depression, emotional and locomotor status of the animals. Keeping these findings in mind, treatment with 5-HT2CR agonist (1-Methylpsilocin at 0.7 mg/kg), and 5-HT2CR antagonist (RS-102221 hydrochloride at 1 mg/kg) displayed varying results. One prominent finding was the anxiolytic ability of the 5-HT2CR agonist and the anti-depressive ability of the 5-HT2CR antagonist on the 7th-day treatment. Though the exact mechanism of action is not clear, their ability to equilibrate brain redox status, restoring Ca2+ level via Ca2+ATPase pump activity, and sustaining the mitochondrial bioenergetics can all be accounted for facilitating neurogenesis and the serotonergic system.

Associations of cigarette smoking with psychiatric disorders: evidence from a two-sample Mendelian randomization study. Sci Rep 2020; 10:13807. [PMID: 32796876 PMCID: PMC7427799 DOI: 10.1038/s41598-020-70458-4] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 06/29/2020] [Indexed: 11/08/2022] Open
Abstract
We conducted a two-sample Mendelian randomization study to determine the association of smoking initiation with seven psychiatric disorders. We used 353 independent single-nucleotide polymorphisms associated with cigarette smoking initiation as instrumental variables at genome-wide significance threshold (p < 5 × 10−8) from a recent genome-wide association study in 1,232,091 European-origin participants. Summary-level data for seven psychiatric disorders, including anxiety, bipolar disorder, insomnia, major depressive disorder, posttraumatic stress disorder, suicide attempts, and schizophrenia, was obtained from large genetic consortia and genome-wide association studies. The odds ratios of genetically predicted smoking initiation were 1.96 for suicide attempts (95% CI 1.70, 2.27; p = 4.5 × 10−20), 1.69 for post-traumatic stress disorder (95% CI 1.32, 2.16; p = 2.5 × 10−5), 1.54 for schizophrenia (95% CI 1.35, 1.75; p = 1.6 × 10−10), 1.41 for bipolar disorder (95% CI 1.25, 1.59; p = 1.8 × 10−8), 1.38 for major depressive disorder (95% CI 1.31, 1.45; p = 2.3 × 10−38), 1.20 for insomnia (95% CI 1.14, 1.25; p = 6.0 × 10−14) and 1.17 for anxiety (95% CI 0.98, 1.40; p = 0.086). Results of sensitivity analyses were consistent and no horizontal pleiotropy was detected in MR-Egger analysis. However, the associations with suicide attempts, schizophrenia, bipolar disorder, and anxiety might be related to possible reverse causality or weak instrument bias. This study found that cigarette smoking was causally associated with increased risks of a number of psychiatric disorders. The causal effects of smoking on suicide attempts, schizophrenia, bipolar disorder and anxiety needs further research.

Abstract
PURPOSE OF REVIEW Anxiety is one of the most common mental health conditions globally and co-occurs with smoking at a markedly high rate. The present review offers a narrative overview of the most recent research on the role of anxiety in smoking onset, maintenance, and cessation-related outcomes. Additionally, given the rise in electronic cigarette use, we review the emerging literature on the influence of anxiety on e-cigarette use. RECENT FINDINGS Evidence across studies varied as to the role of anxiety or anxiety symptoms in smoking behavior. The most consistent findings suggested that those with anxiety are more likely to be a smoker, supporting a high rate of co-occurrence across these conditions. Less consistent evidence was observed for the association between anxiety and onset, indicators of severity, and cessation outcomes. Although there is robust evidence for an association between smoking and anxiety, there were considerable discrepancies for the precise role of anxiety in smoking onset, severity, and cessation outcomes. Future work utilizing more sophisticated methodologies is needed to identify causal relations as well as putative moderators and mediators of the anxiety-smoking relation.

Abstract
Objective: To assess factors associated with anxiety among a sample of the Lebanese population.Methods: A cross-sectional, conducted between November 2017 and March 2018, enrolled 789 participants. Anxiety was measured using the Hamilton Anxiety Scale. A cluster analysis was then performed with the identified factor scores to identify the different profiles of the participants.Results: A cluster analysis based on the three factors derived three mutually exclusive clusters, which form 29.62%, 34.54%, and 35.84% of all participants, respectively. The first cluster represented people in distress (low emotional intelligence, high depersonalisation, alcohol use disorder, burnout, stress, alexithymia and low self-esteem); the second one represented people with wellbeing (High emotional intelligence, low depersonalisation, low alcohol use disorder, low burnout, low stress, low alexithymia and high self-esteem), whereas cluster 3 represented people in between. Higher age (Beta = 0.065) was significantly associated with higher anxiety, whereas being in cluster 2 (people with wellbeing) (Beta = -12.37) and cluster 3 (people in between) (Beta = -5.426) were significantly associated with lower anxiety compared to being in cluster 1 (people in distress).Conclusions: The findings of this study are overall consistent with those of epidemiologic community-based surveys and may help inform structural models of classification and prediction of anxiety disorders (ADs).

Abstract
PURPOSE To compare the prevalence and severity of depression and anxiety among patients with vocal fold (VF) nodules, polyps and edema. At the same time the aim was to analyse association between severity of distress and the level of vocal handicap as well as to identify other factors related to severity of depression and anxiety in these patients. METHODS To all participants were given five questionnaires: (1) questionnaire on socio-demographic and some other characteristics of patient; (2) Beck's Depression Inventory (BDI); (3) State-Trait Anxiety Inventory (STAI) 1 (State Anxiety); (4) STAI 2 (Trait Anxiety); and (5) Voice Handicap Index (VHI)-10. RESULTS A total of 205 patients were included in this study. Mild-to-severe depression, according to BDI was present in 79 (38.6%) patients. Mild-to-severe state anxiety and trait anxiety were present in 199 (97.1%) and 200 (97.6%) patients, respectively. Only 10 patients had VHI-10 score ≤ 11. Multivariate analyses showed that there were no significant differences in the level of depression and anxiety between patients with VF nodules, polyps and edema. The VHI-10 score was significantly higher in patients with VF edema in comparison with VF nodule patients (p = 0.001), as well as in comparison with VF polyp patients (p = 0.001). CONCLUSION The present study identified a high prevalence of psychological and vocal distress among patients with vocal disorders. Severity of depression and anxiety did not differ between patients with VF nodules, polyps and edema, and it was not related to the level of vocal handicap.

Abstract
The present study aimed to assess the behavioral effects of chronic treatments of different doses of nicotine by using both quantitative and multivariate T-pattern analysis (TPA), which can reveal hidden behavioral structures, in Sprague-Dawley rats tested in the hole-board apparatus. To this purpose, nicotine ditartrate was administered at the doses of 0.1, 0.5 and 1 mg/kg i.p., three times per day, for 14 consecutive days. As to quantitative evaluations, we observed significant reductions in the mean durations and mean frequencies of walking, climbing, immobile-sniffing and rearing in comparison to control. A significant reduction of edge-sniff and head-dip mean frequencies was also detected for all the doses tested. TPA revealed an increase in the number and the mean length of different T-patterns induced by the three doses of nicotine. On the other hand, a significant reduction of the mean occurrences of T-patterns was revealed. Overall, our results obtained by using both quantitative and T-pattern analyses indicate that chronic nicotine induces an anxiety condition characterized by a behavioral re-organization orbiting around the two main components of hole exploration, that is, head-dip and edge-sniff. A better understanding of the link between nicotine and anxiety might help to find new therapies for smoking cessation.

Abstract
Men who have sex with men (MSM) and are living with HIV have reported high rates of intimate partner violence (IPV) and substance use. We examined relationships between accumulative IPV, incidents of IPV, and numbers of substances used. One hundred twenty Taiwanese MSM living with HIV completed a cross-sectional survey. Accumulative IPV was assessed by summing the number of 15 types of IPV experienced in the previous year; substance use was measured by any use of alcohol, tobacco, or other drugs during the previous week. In multivariate analysis, IPV was not associated with tobacco use but was positively associated with alcohol and other drug use and significantly associated with the probability of using multiple substances. MSM living with HIV who experienced greater IPV were more likely to use alcohol and other drugs and were more likely to use more than one substance. Health care providers screening for IPV should also screen for substance use.

Abstract
BACKGROUND Family smoking environment and family management are associated with risk of teen smoking behaviors. However, less is known about whether these associations increase or decrease in strength across adolescence, and whether there are person-environment interactions. The current study examined 1) the age-varying main effects of family smoking and family management on adolescent daily smoking from ages 12-18 and tested 2) whether behavioral disinhibition and anxiety moderated these relationships. METHODS Data were drawn from the Seattle Social Development Project (SSDP; N = 808), a longitudinal study examining prosocial and antisocial behavior. Analyses used time-varying effect modeling (TVEM), which tested the stability of the relationship between family smoking and family management and youth daily smoking across adolescence. RESULTS Greater family smoking increased the likelihood of adolescent daily smoking, whereas greater family management reduced the likelihood of daily smoking. Significant interactions between family management and youth behavioral disinhibition and anxiety during early and mid-adolescence indicated that family management was more protective for adolescents with low (compared to high) behavioral disinhibition and anxiety. The effect of family smoking was not moderated by behavioral disinhibition or anxiety. CONCLUSIONS Family smoking and family management are key risk and protective factors that may be targeted for adolescent smoking prevention. Our interaction results for individual differences in behavioral disinhibition and anxiety suggest that certain types of youth may respond differently to family management practices. Findings also show periods during adolescence where family-centered preventive interventions could be optimally timed to prevent or reduce persistent adolescent smoking.

Abstract
OBJECTIVE Exposure to airborne particulate matter (PM) is estimated to cause millions of premature deaths annually. This work conveys known routes of exposure to PM and resultant health effects. METHODS A review of available literature. RESULTS Estimates for daily PM exposure are provided. Known mechanisms by which insoluble particles are transported and removed from the body are discussed. Biological effects of PM, including immune response, cytotoxicity, and mutagenicity, are reported. Epidemiological studies that outline the systemic health effects of PM are presented. CONCLUSION While the integrated, per capita, exposure of PM for a large fraction of the first-world may be less than 1 mg per day, links between several syndromes, including attention deficit hyperactivity disorder (ADHD), autism, loss of cognitive function, anxiety, asthma, chronic obstructive pulmonary disease (COPD), hypertension, stroke, and PM exposure have been suggested. This article reviews and summarizes such links reported in the literature.

Abstract
UNLABELLED Tobacco smoking remains common among medical students, something which may impact on their abililty to promote smoking cessation during their future careers. OBJECTIVES To determine the prevalence of smoking and consumption among French medical students and explore the link between both the presence of psychosocial factors and consumption of psychotropic medication and the severity of nicotine dependence and daily smoking behavior. METHODS Medical students were recruited from 35 French universities of medicine through administration mailing lists and social networks, between December 13, 2016 and May 15, 2017. Data was collected via anonymized Internet questionnaire which included questions regarding current daily tobacco smoking behaviors. Severe nicotine dependence was defined by a short Fagerström test equal or >4. RESULTS 10,985 medical students with a mean aged of 21.8 years (+/-3.3) were included, 31.6% of which were male. 2078 (18.9%) were identified as current daily tobacco smokers and 59 (2.8%) were classed as having severe nicotine dependence. In multivariate analyses, tobacco smoking was independently associated with anxiolytic consumption, alcohol use disorder, cannabis use disorder, financial difficulties, and history of sexual and physical assault. Severe nicotine dependence was independently associated with anxiolytic consumption, cannabis use disorder, domestic violence, physical assault and financial difficulties. CONCLUSION Tobacco smoking has been found in almost one on 5 medical students and is associated with anxiolytic consumption as well as professional and personal factors.

Abstract
The aim of this paper is to report findings on the epidemiology of generalized anxiety disorder (GAD) using data from the Singapore Mental Health Study (SMHS) 2016, and draw comparisons with results from the first SMHS in 2010. Singapore residents aged 18 years and above participated in the household survey where the WHO Composite International Diagnostic Interview 3.0 was administered to assess the prevalence of GAD and other mental health conditions. The findings revealed that the lifetime prevalence of GAD was 1.6% among the Singapore general population in 2016, an increase from the 0.9% in 2010. More lifetime GAD cases were reported across several sociodemographic groups including age and employment status. Lifetime GAD was significantly associated with higher odds of several comorbid psychiatric conditions (OR = 3.8-9.3, p < 0.05). Treatment seeking behavior did not differ significantly when compared to SMHS 2010 and there was still a considerable treatment gap among individuals with GAD. Future intervention programs to reduce anxiety and encourage help-seeking behavior could be implemented at institutes of higher learning and workplace settings to reach the targeted audience.

Abstract
BACKGROUND Several lines of investigations support the idea that nicotinic acetylcholine receptors modulate neuronal pathways involved in anxiety and depression. AIMS The purpose of this study was to determine whether 3-furan-2-yl-N-p-tolyl-acrylamide, a highly selective positive allosteric modulator of α7 nicotinic acetylcholine receptors, influences anxiety-like behaviour in mice, and to determine the modulatory activity of 3-furan-2-yl-N-p-tolyl-acrylamide on mice pretreated with either nicotine or selective α7-agonists (i.e. PNU-282987 or (2.4)-dimethoxybenzylidene anabaseine dihydrochloride). METHODS The elevated plus maze and novelty suppressed feeding tests were selected to evaluate 3-furan-2-yl-N-p-tolyl-acrylamide and other nicotinic ligands on anxiety-like behaviour in mice. RESULTS The results indicated that: (a) 3-furan-2-yl-N-p-tolyl-acrylamide induces anxiolytic-like activity at 0.5 (elevated plus maze) and 1.0 (novelty suppressed feeding) mg/kg, respectively, after acute treatment, whereas its efficacy is increased after chronic treatments (i.e. active at 0.1 mg/kg; elevated plus maze). This is the first time showing anxiolytic-like activity elicited by 3-furan-2-yl-N-p-tolyl-acrylamide, contrary to the lack of activity for PNU-120596 (0.1 mg/kg); (b) the anxiolytic-like activity of 0.5 mg/kg 3-furan-2-yl-N-p-tolyl-acrylamide is inhibited by methyllycaconitine, a selective α7-antagonist, suggesting that α7 nicotinic acetylcholine receptors are involved in this process; (c) 0.5 mg/kg 3-furan-2-yl-N-p-tolyl-acrylamide reverses the anxiogenic effects induced by 0.1 mg/kg nicotine but not by 10.0 mg/kg PNU-282987; and (d) inactive doses of both 3-furan-2-yl-N-p-tolyl-acrylamide (0.1 mg/kg) and (2.4)-dimethoxybenzylidene anabaseine dihydrochloride (1.0 mg/kg) produce anxiolytic-like effects, suggesting drug interactions, probably synergistic. CONCLUSIONS Our findings indicated that anxiolytic-like activity is mediated by α7 nicotinic acetylcholine receptors, supporting the concept that these receptors modulate anxiety processes. The results indicating that the chronic treatment with 3-furan-2-yl-N-p-tolyl-acrylamide is more efficient than the acute treatment in eliciting anxiolytic-like activity, and that 3-furan-2-yl-N-p-tolyl-acrylamide reverses the anxiogenic effects induced by nicotine, might be of therapeutic importance during smoking cessation.

Abstract
Nicotine use and psychological distress exert negative bidirectional effects on one another, and are impacted by shared vulnerabilities. Little work has examined the extent to which these relations differ between adult electronic nicotine delivery system (ENDs) users with varied combustible cigarette use histories. The current study examined differences in internalizing symptoms and vulnerabilities between adult dual and single ENDs users with and without a history of combustible cigarette use. Single ENDs users without combustible use histories reported significantly greater stress and anxiety symptoms than single ENDs users with combustible use histories. Single ENDs users without combustible use histories reported greater anxiety and difficulty regulating their emotions than dual-users. Dual-and single users with prior combustible use histories did not differ in internalizing pathology or vulnerability presentations. This suggests that pathology and vulnerability presentation among nicotine users are influenced by both current and past nicotine use history.

Abstract
BACKGROUND Several studies worldwide have pointed to depression and anxiety symptoms as being related to adolescent smoking. The aim of this study was to investigate, the potential link of cigarette smoking with depression, anxiety, and suicidal ideation and the influence of gender on these relationships in Brazilian adolescents. METHODS Associations of smoking with Children Depressive Inventory version 2 (CDI2) scores, Hamilton Anxiety Scale (HAM-A) scores, and poor school performance (i.e., grade retention) were examined in 988 Brazilian students (age range, 11-17 years) enrolled in 82 public and private schools. Logistic regression modeling was employed and the resultant odds ratios (ORs) are reported with 95% CIs. RESULTS Of 988 participants, 240 (24.3%) were smokers. Mean (±standard error) HAM-A scores were higher for smokers (21.1 ± 9.7) than nonsmokers (15.4 ± 8.6; p < 0.0001). Relative to nonsmokers, smokers had higher total CDI2 scores (p = 0.033), and higher scores for the CDI2 domains of Emotional Problems (p = 0.023), Negative Self-esteem (p < 0.001), and Functional Problems (p = 0.046). Suicidal ideation was common among smokers with depressive symptoms (54.2%). Smoking was associated with being held back three grades (p < 0.001). Female smokers were more likely to report suicidal ideation than male smokers (p = 0.020). Logistic regression modeling revealed significant associations of suicidal ideation with being female (OR, 1.81; 95% CI, 1.38-2.37), being a female smoker (OR, 2.05; 95% CI, 1.51-2.80), and having a HAM-A score > 16 (OR, 2.18; 95% CI, 1.66-2.86). CONCLUSION Smoking was found to be associated with anxiety symptoms, depressive symptoms, and poor school performance in Brazilian adolescents; and female smokers reported more suicidal ideation than male smokers.

Abstract
Background: The purpose of this systematic review was to examine the association and directionality between mental health disorders and substance use among adolescents and young adults in the U.S. and Canada. Methods: The following databases were used: Medline, PubMed, Embase, PsycINFO, and Cochrane Library. Meta-analysis used odds ratios as the pooled measure of effect. Results: A total of 3656 studies were screened and 36 were selected. Pooled results showed a positive association between depression and use of alcohol (odds ratio (OR) = 1.50, 95% confidence interval (CI): 1.24–1.83), cannabis (OR = 1.29, 95% CI: 1.10–1.51), and tobacco (OR = 1.65, 95% CI: 1.43–1.92). Significant associations were also found between anxiety and use of alcohol (OR = 1.54, 95% CI: 1.19–2.00), cannabis (OR = 1.36, 95% CI: 1.02–1.81), and tobacco (OR = 2.21, 95% CI: 1.54–3.17). A bidirectional relationship was observed with tobacco use at baseline leading to depression at follow-up (OR = 1.87, CI = 1.23–2.85) and depression at baseline leading to tobacco use at follow-up (OR = 1.22, CI = 1.09–1.37). A unidirectional relationship was also observed with cannabis use leading to depression (OR = 1.33, CI = 1.19–1.49). Conclusion: This study offers insights into the association and directionality between mental health disorders and substance use among adolescents and young adults. Our findings can help guide key stakeholders in making recommendations for interventions, policy and programming.

Abstract
Aim, materials & methods: Urinary cortisol profile has the potential as a diagnostic biomarker. We therefore developed a stable-isotope dilution ultraperformance chromatography multistage MS-based method to quantify cortisol and 16 metabolites in human urines. Results & conclusion: The LOD for cortisol and its metabolites ranges from 0.02 to 5.81 pg/μl urine. The inter- and intraday variations were 3.7-12.9% and 3.5-15.6%, respectively. Among the metabolites analyzed, significant person-to-person heterogeneity was observed, demonstrating the need for comprehensive metabolite profiling in diagnosis. Nevertheless, the glucuronides of dihydrocortisol, dihydrocortisone, tetrahydrocortisol, allo-tetrahydrocortisol and tetrahydrocortisone are the major ones. The sum of the glucuronidated and free forms constitute >93% of the metabolites analyzed, which is termed as total cortisol equivalent. Total cortisol equivalent may serve as a surrogate of cortisol secretion. Clinical trial registration number: NCT02500472.

Abstract
Earlier studies have shown that combination of antibodies to S100 protein and to cannabinoid receptor type 1 in released-active form (Brizantin) may possess anxiolytic properties and decrease nicotine dependence. Released-active form of antibodies is a novel approach that permits to modify natural functions of the target molecule (antigen) under investigation. The aim of the present study was to evaluate the anxiolytic-like effect of Brizantin in the light-dark test in mice, according to its ability to influence the number of entries into the lit compartment and the total time spent there. Three doses of Brizantin (2.5, 5, and 10 mL/kg) were compared with diazepam (1 mg/kg), placebo, and vehicle control. Anxiolytic-like effect of the tested drug was shown to be dose dependent, with an increasing trend from 2.5 to 10 mL/kg. Brizantin in its highest dose significantly increased studied behavioral parameters, although its effect was less pronounced than that of the reference drug diazepam (1 mg/kg).

Abstract
Smoking is the cause of addictive behavior. Tobacco addiction is a chronic disease that makes difficult to stop smoking and leads to further use. Smoking is a risk factor for COPD, asthma and lung cancer; it may be the cause of severe perioperative complications. This finding justifies that smokers benefit from advice of stopping smoking and smoking cessation assistance. Helping patients to stop smoking increases the chances of quitting, improves the prognosis of tobacco-related diseases, the effectiveness of their treatments and the quality of life of the patients. This article updates the modalities of smoking cessation assistance in smokers with COPD, asthma and lung cancer in operated patients. The goal of the management must be the complete cessation of tobacco smoke intoxication, which alone reduces tobacco mortality.

Abstract
AIMS AND OBJECTIVES To explore the relationship between smoking and other risk behaviours among Chinese young people in Hong Kong. BACKGROUND There is growing concern about coexisting risk behaviours in young smokers. Information about smoking and other risk behaviours is crucial for developing interventions to promote smoking abstinence and adoption of healthy lifestyles. The relationship between smoking and other risk behaviours among Chinese young people in Hong Kong has not been explored. DESIGN This is a mixed-method retrospective population-based study. METHODS A retrospective population-based study was conducted with 1,147 young smokers through Youth Quitline between November 2011-July 2016. Attitudes, behaviours and experiences related to smoking and risk behaviours among Chinese young smokers were examined in semi-structured qualitative interviews with 30 participants randomly selected from the retrospective population-based study. RESULTS In total, 45.5% participants reported engaging in at least one other risk behaviour. The interviews revealed that drinking alcohol may have a significant impact on quitting smoking. In addition, smoking may be a gateway for more serious risk behaviours during adolescence. Low health awareness may explain the unhealthy lifestyles among young smokers. CONCLUSIONS This study bridges a gap in existing literature by exploring relationships between smoking and other risk behaviours among young people in Hong Kong. RELEVANCE TO CLINICAL PRACTICE Given the interrelationships between smoking and other risk behaviours, a holistic approach should be used to promote smoking cessation and healthy lifestyles among young smokers. If young smokers improve their health and quit smoking at the same time, their physical and mental development will benefit as a secondary outcome.

Abstract
Smokers, who generally present with lung damage, are more anxious than non-smokers and have an associated augmented risk of panic. Considering that lung damage signals specific neural pathways that are related to affective responses, the aim of the present study was to evaluate the influence of pulmonary injury on anxiety and panic-like behaviours in animals exposed to cigarette smoke with and without tobacco. Male Wistar rats were divided into the following groups: a control group (CG); a regular cigarette group (RC); and a tobacco-free cigarette (TFC) group. Animals were exposed to twelve cigarettes per day for eight consecutive days. The animals were then exposed to an elevated T-maze and an open field. The RC and TFC groups presented increases in inflammatory cell inflow, antioxidant enzyme activity, and TBARS levels, and a decrease in the GSH/GSSG ratio was observed in the TFC group. Exposure to RC smoke reduced anxiety and panic-related behaviours. On the other hand, TFC induced anxiety and panic-related behaviours. Thus, our results contradict the concept that nicotine is solely accountable for shifted behavioural patterns caused by smoking, in that exposure to TFC smoke causes anxiety and panic-related behaviours.

Abstract
Background Evidence on the effects of lack of physical exercise, alcohol drinking and smoking on happiness is limited and inconsistent. We examined the associations of unhappiness with sociodemographic factors and these unhealthy behaviours in Chinese adolescents. In a school-based survey in 2012-13 in Hong Kong, 45 857 secondary school students (mean age 14.8 years, 54.0% boys) reported their happiness level (not happy at all/not very happy/happy/very happy), frequency of physical exercise, alcohol drinking status, smoking status and sociodemographic factors. A main and a sensitivity analysis examined the associations of unhappiness with the study factors, treating unhappiness as a binary (combining 'not happy at all' and 'not very happy') and a four-level ordered variable, respectively. The main and the sensitivity analysis both showed that unhappiness was associated with older age, very poor families, non-intact families, more co-residing smokers, lack of physical exercise and alcohol drinking; current smokers were unhappier than never and ex-smokers; unhappiness also increased significantly with the number of unhealthy behaviours ( P for trend < 0.001). In Chinese adolescents, unhappiness levels were higher in those who had a very poor family, a non-intact family and more co-residing smokers, and in those who were physically inactive, drank alcohol and smoked.

Abstract
Behavioural interventions show promising results among patients with mild- to moderate depression. However, whether tobacco use moderates the effects of these interventions is not known. In the present study, we examined whether patients suffering from mild-to-moderate depression differed in their response to prescribed physical exercise or internet-based cognitive behavioural therapy (ICBT) according to their current tobacco use. We conducted a secondary analysis of data from 740 participants in a multicentre randomised controlled trial comparing physical exercise, internet-based cognitive behavioural therapy and treatment as usual (Regassa study). Information on current daily tobacco use was self-reported at baseline. Linear and logistic regression were used to examine the treatments' effect (reduction in depression score) in the subgroups of tobacco users (n=154) and non-users (n=586). We found that baseline tobacco use did not significantly moderate the association between treatment type and post-treatment depression severity. Both interventions (exercise and ICBT) resulted in a reduction of depression scores that was similar among non-users and users of tobacco, albeit formally statistically significant only among non-users. Physical exercise on prescription and ICBT can be used in the clinical management of depressed patients, with similar prognostic advantage among tobacco users and non-users.

Adapting, Pilot Testing and Evaluating the Kick.it App to Support Smoking Cessation for Smokers with Severe Mental Illness: A Study Protocol. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15020254. [PMID: 30720772 PMCID: PMC5858323 DOI: 10.3390/ijerph15020254] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 01/27/2018] [Accepted: 01/30/2018] [Indexed: 12/28/2022]
Abstract
(1) Background: While the prevalence of tobacco smoking in the general population has declined, it remains exceptionally high for smokers with severe mental illness (SMI), despite significant public health measures. This project aims to adapt, pilot test and evaluate a novel e-health smoking cessation intervention to assist relapse prevention and encourage sustained smoking cessation for young adults (aged 18⁻29 years) with SMI. (2) Methods: Using co-design principles, the researchers will adapt the Kick.it smartphone App in collaboration with a small sample of current and ex-smokers with SMI. In-depth interviews with smokers with SMI who have attempted to quit in the past 12 months and ex-smokers (i.e., those having not smoked in the past seven days) will explore their perceptions of smoking cessation support options that have been of value to them. Focus group participants will then give their feedback on the existing Kick.it App and any adaptations needed. The adapted App will then be pilot-tested with a small sample of young adult smokers with SMI interested in attempting to cut down or quit smoking, measuring utility, feasibility, acceptability, and preliminary outcomes in supporting their quit efforts. (3) Conclusions: This pilot work will inform a larger definitive trial. Dependent on recruitment success, the project may extend to also include smokers with SMI who are aged 30 years or more.

Abstract
Importance While the adverse association between smoking and head and neck squamous cell carcinoma (HNSCC) survival has been well described, there are also inconclusive studies and those that report no significant changes in HNSCC survival and overall mortality due to smoking. There is also a lack of studies investigating the association of marital status on smoking status at diagnosis for patients with HNSCC. Objective To examine the association between patient smoking status at HNSCC diagnosis and survival and the association between marital status and smoking in these patients. Design, Setting, and Participants This retrospective cohort study was conducted by querying the Saint Louis University Hospital Tumor Registry for adults with a diagnosis of HNSCC and treated at the university academic medical center between 1997 and 2012; 463 confirmed cases were analyzed. Main Outcomes and Measures Cox proportional hazards regression analysis was used to evaluate association of survival with smoking status at diagnosis and covariates. A multivariate logistic regression model was used to assess whether marital status was associated with smoking at diagnosis adjusting for covariates. Results Of the 463 total patients (338 men, 125 women), 92 (19.9%) were aged 18 to 49 years; 233 (50.3%) were aged 50 to 65 years; and 138 (29.8%) were older than 65 years. Overall, 56.2% of patients were smokers at diagnosis (n = 260); 49.6% were married (n = 228); and the mortality rate was 54.9% (254 died). A majority of patients were white (81.0%; n = 375). Smokers at diagnosis were more likely to be younger (ie, <65 years), unmarried, and to drink alcohol. We found a statistically significant difference in median survival time between smokers (89 months; 95% CI, 65-123 months) and nonsmokers at diagnosis (208 months; 95% CI, 129-235 months). In the adjusted Cox proportional hazards model, patients who were smokers at diagnosis were almost twice as likely to die during the study period as nonsmokers (hazard ratio, 1.98; 95% CI, 1.42-2.77). In the multivariate logistic regression analysis, unmarried patients were 76% more likely to use tobacco than married patients (adjusted odds ratio, 1.76; 95% CI, 1.08-2.84). Conclusions and Relevance Smokers were almost twice as likely as nonsmokers to die during the study period. We also found that those who were married were less likely to be smokers at diagnosis. Our study suggests that individualized cancer care should incorporate social support and management of cancer risk behaviors.

Maternal Smoking in Pregnancy and Offspring Depression: a cross cohort and negative control study. Sci Rep 2017; 7:12579.

Abstract
Previous reports suggest that offspring of mothers who smoke during pregnancy have greater risk of developing depression. However, it is unclear whether this is due to intrauterine effects. Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) from the UK (N = 2,869), the Nord-Trøndelag health study (HUNT) from Norway (N = 15,493), the Pelotas 1982 Birth Cohort Study from Brazil (N = 2,626), and the Swedish Sibling Health Cohort (N = 258 sibling pairs), we compared associations of maternal smoking during pregnancy and mother’s partner’s smoking during pregnancy with offspring depression and performed a discordant sibling analysis. In meta-analysis, maternal smoking during pregnancy was associated with higher odds of offspring depression (OR 1.20, 95% CI:1.08,1.34), but mother’s partner’s smoking during pregnancy was not (OR 1.05, 95% CI:0.94,1.17). However, there was only weak statistical evidence that the odds ratios for maternal and mother’s partner’s smoking differed from each other (p = 0.08). There was no clear evidence for an association between maternal smoking during pregnancy and offspring depression in the sibling analysis. Findings do not provide strong support for a causal role of maternal smoking during pregnancy in offspring depression, rather observed associations may reflect residual confounding relating to characteristics of parents who smoke.

Abstract
Smoking is the leading cause of death in the United States. It exerts its effects by increasing susceptibility to a variety of complex disorders among those who smoke, and if pregnant, to their unborn children. In prior efforts to understand the epigenetic mechanisms through which this increased vulnerability is conveyed, a number of investigators have conducted genome wide methylation analyses. Unfortunately, secondary to methodological limitations, these studies were unable to examine methylation in gene regions with significant amounts of genetic variation. Using genome wide genetic and epigenetic data from the Framingham Heart Study, we re-examined the relationship of smoking status to genome wide methylation status. When only methylation status is considered, smoking was significantly associated with differential methylation in 310 genes that map to a variety of biological process and cellular differentiation pathways. However, when SNP effects on the magnitude of smoking associated methylation changes are also considered, cis and trans-interaction effects were noted at a total of 266 and 4353 genes with no marked enrichment for any biological pathways. Furthermore, the SNP variation participating in the significant interaction effects is enriched for loci previously associated with complex medical illnesses. The enlarged scope of the methylome shown to be affected by smoking may better explicate the mediational pathways linking smoking with a myriad of smoking related complex syndromes. Additionally, these results strongly suggest that combined epigenetic and genetic data analyses may be critical for a more complete understanding of the relationship between environmental variables, such as smoking, and pathophysiological outcomes.

Abstract
Prenatal stress and prenatal nutrition each have demonstrable impact on fetal development, with implications for child neurodevelopment and behavior. However, few studies have examined their joint influences despite evidence of potential interactive effects. We examined associations among prenatal stress, prenatal antioxidant intakes, and child temperament in a sociodemographically diverse pregnancy cohort (N=137 mother-child dyads). In mid-pregnancy, mothers completed an assessment of recent negative life events as a measure of prenatal stress and an assessment of prenatal diet. When the children were 30 months of age, mothers completed the Early Childhood Behavior Questionnaire-Very Short form, which provides scores on child Negative Affectivity, Effortful Control, and Surgency/Extraversion. Linear regressions tested associations between maternal prenatal negative life events and child temperament, and effect modification by maternal prenatal antioxidant intakes (vitamins A, C, and E, magnesium, zinc, selenium, β-carotene). Analyses revealed that increased maternal prenatal negative life events were associated with higher child Negative Affectivity (β=0.08, P=0.009) but not with child Effortful Control (β=-0.03, P=0.39) or Surgency/Extraversion (β=0.04, P=0.14). Prenatal intakes of zinc and selenium modified this effect: Maternal exposure to prenatal negative life events was associated with higher child Negative Affectivity in the presence of lower intakes of zinc and selenium. Modification effects approached significance for vitamins A and C. The results suggest that the combination of elevated stress exposures and lower antioxidant intakes in pregnancy increases the likelihood of heightened child temperamental negative affectivity. Increased antioxidant intakes during pregnancy may protect against influences of prenatal stress on child temperament.

Abstract
OBJECTIVE Identifying the level of anxiety, stress and depression symptoms in family members of patients with heart failure; identifying the relationship between these feelings with sociodemographic and clinical variables. METHOD A cross-sectional study carried out with 100 family members. Depression, anxiety, and stress were evaluated by the Beck Depression and Anxiety Inventories and the Perceived Stress Scale - 10. The relationship between feelings and variables was performed through the t-test, Mann-Whitney or Kruskal-Wallis. RESULTS Mean depression was 8.24, anxiety was 77.95, and stress was 17.43. The correlation coefficient between depression and anxiety and depression and stress was 0.53, and it was 0.66 between anxiety and stress. Females (p=0.002, p=0.031), smoking (p=0.05, p=0.011) and sedentary lifestyle (p=0.023, p=0.001) were related to anxiety and stress, respectively. Family income lower than five minimum wages (p=0.012) was related to depression, and regular/poor self-perceived health status related to the three feelings. CONCLUSION Family members did not present high levels of these feelings. The scales were directly correlated with each one another and some variables were related to stress, anxiety and depression. OBJETIVO Identificar o nível de ansiedade, estresse e sintomas de depressão de familiares de pacientes com insuficiência cardíaca; identificar a relação entre esses sentimentos com as variáveis sociodemográficas e clínicas.

Abstract
OBJECTIVE The aims of this study were to investigate: (1) the prevalence and unadjusted and adjusted odds of 12-month generalized anxiety disorder (GAD) among adults with migraine in comparison to those without migraine; (2) If debilitating pain and/or limitations in instrumental activities of daily living (IADLs) are mediators of the migraine-GAD association; and (3) Factors associated with past year GAD among adults with migraine. METHODS Secondary data analysis of the nationally representative 2012 Canadian Community Health Survey-Mental Health (CCHS-MS), a population-based survey of community dwellers with a response rate of 68.9%. The first subsample included those with (n = 2232) and without migraine (n = 19,270), and the second subsample was restricted to those with migraine (n = 2232). GAD was based on the WHO-CIDI scale. RESULTS Fully, 6% of those with migraines had past year GAD in comparison of 2.1% of those without migraine (P < .001). The socio-demographically adjusted odds of past year GAD were two and a half times higher among those with migraine than those without (OR= 2.46; 95% CI = 2.00, 3.02). A path analysis indicated that debilitating pain and limitations in IADLs were mediators in the relationship between migraine and GAD. In the sample restricted to migraineurs, the factors associated with higher odds of 12-month GAD included having a university degree, having low income, being without a confidant, and being male. CONCLUSIONS Generalized anxiety disorder is robustly associated with migraine and targeted outreach and interventions are warranted.

Abstract
Cigarette smoking is known to be harmful to health, and is considered the main cause of death worldwide, especially in India. Among the well-distinguished diseases related to smoking are, chronic obstructive pulmonary disease, oral and peripheral cancers, and cardiovascular complications. However, the impact of cigarette smoking on neurocognitive and neuropathological effects, including anxiety, Alzheimer's disease, Parkinson's disease, ischemic stroke, and blood-brain barrier dysfunction, still remains unclear. Cigarette smoke consists of more than 4500 toxic chemicals that combine to form free radicals, which lead to oxidative stress-associated neurological disorders. Herein, we discuss the role of antioxidant agents in delaying or attenuating disease complications. In addition, in this review, we discuss the neuropathological effect of cigarette smoke and its interference in neurodegeneration.

Abstract
OBJECTIVE This study was designed to examine the independent and combined associations of physical activity and smoking on the incidence of doctor-diagnosed insomnia using a nationally representative sample over seven years, taking into account other relevant covariates. METHODS Participants aged 18 years or older in the 2005 Taiwan National Health Interview Survey (NHIS) with links to National Health Insurance (NHI) claim data between 2005 and 2012 and without diagnosed insomnia before 2005, were selected into this study (n = 12,728). Participants were classified as having insomnia with International Classification of Diseases, Ninth Revision (ICD-9) CM codes 307.41, 307.42, or 780.52. Self-reported smoking status and frequency, duration, and types of leisure-time and non-leisure-time physical activities were collected. Metabolic equivalent (MET) intensity levels for each activity were assigned, and weekly energy expenditure of each activity was calculated and summed. RESULTS Inactive participants had a higher risk of incident insomnia [hazard ratio (HR) = 1.22, 95% confidence interval (CI) = 1.06-1.42, p = 0.007] than the active group, and ever-smokers were more likely to have incident insomnia than never smokers (HR = 1.45, 95% CI = 1.20-1.76, p < 0.001). Compared with the nonsmoker/active group, the ever-smoker/inactive group had a higher risk of incident insomnia (HR = 1.78, 95% CI = 1.41-2.25, p < 0.001). Sensitivity analyses excluding individuals diagnosed with other sleep disorders or mental disorders yielded similar results, with the ever-smoker/inactive group having the highest risk of insomnia. CONCLUSIONS Inactive adults and smokers are at higher risk for incident insomnia, highlighting the importance of a healthy lifestyle and pointing to strategies such as encouraging smoking cessation and physical activity to avoid insomnia among adults.

Abstract
<b>Background</B><br />
One of the smoking risk factors influencing nicotine dependency may be human personality; however, few studies have examined the association between Akiskal’s affective temperaments and smoking in adults. Our study aims to evaluate the associations between nicotine dependence and affective temperaments using the TEMPS-A.<br />
<br />
<b>Participants and procedure</B><br />
The sample in this study consisted of 678 healthy Caucasian adults aged from 17 to 69 years, including 134 self-declared nicotine-dependent subjects (89 females and 45 males) and 544 self-declared non-nicotine-dependent subjects (352 females and 192 males). The Polish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) was used to assess affective temperaments (depressive, cyclothymic, hyperthymic, irritable and anxious).<br />
<br />
<b>Results</B><br />
Nicotine-dependent individuals scored higher on cyclothymic, irritable and anxious temperaments than non-nicotine-dependents (no significant differences with regard to depressive and hyperthymic temperaments). Among the nicotine-dependent individuals, females scored higher on anxious temperaments than males (no differences with regard to the other affective temperaments), and among the non-nicotine-dependent individuals, females exhibited more depressive, cyclothymic and anxious temperaments than males, while males exhibited more hyperthymic temperaments than females.<br />
<br />
<b>Conclusions</B><br />
The results suggest that affective, cyclothymic and irritable temperaments in both genders and anxious temperaments in females may be predictors of nicotine dependence in adults.

Abstract
In this short essay, I wish to briefly discuss smoking, polypharmacy, the human biome and multispecies relations, and biomedicalization as a means of stretching the common ways we think about comorbidity. My intent is to expand our thinking about comorbidity and multimorbidity beyond the individual as a unit of analysis, to reframe comorbidity in relation to trajectories of risk, and to address comorbid states of our own making when the treatment of one health problem results in the experience of additional health problems. I do so as a corrective to what I see as an overly narrow focus on comorbidity as co-occurring illnesses within a single individual, and as a complement to critical medical anthropological assessments of synergistic comorbid conditions (syndemics) occurring in structurally vulnerable populations living in environments of risk exposed to macro and micro pathogenic agents.

Abstract
HIV/AIDS and anxiety/depression are interlinked. HIV-infected patients suffering from depression may be at risk for poor adherence which may contribute to HIV disease progression. Additionally, an HIV diagnosis and/or using certain antiretroviral agents may trigger symptoms of anxiety/depression. The objective of the study was to assess the prevalence and factors associated with anxiety and depression in HIV-infected patients from the Thai National HIV Treatment Program. This cross-sectional study was performed from January 2012 to December 2012 in HIV-infected out-patients, aged ≥18 years, from three HIV referral centers. Symptoms of anxiety and depression were measured using the Thai-validated Hospital Anxiety and Depression Scale (HADS). A score of ≥11 was defined as having anxiety and depression. Associated factors were assessed by multivariate logistic regression. Totally 2023 (56% males) patients were enrolled. All patients received antiretroviral therapy (ART) for a mean duration of 7.7 years. Median CD4 was 495 cells/mm3. Ninety-five percent had HIV-RNA < 50 copies/ml. Thirty-three percent were currently on efavirenz (EFV)-based ART. The prevalence of anxiety and depression were 4.8% and 3.1%, respectively. About 1.3% had both anxiety and depression. In multivariate logistic models, the female sex [OR = 1.6(95%CI 1.1-2.3), p = .01], having adherence <90% [OR = 2.2(95%CI 1.5-3.4), p < .001], fair/poor quality of life (QOL) [OR = 7.2 (95%CI 3.6-14.2), p < .001] and EFV exposure [OR = 1.6(95%CI 1.1-2.3), p = .01], were independently associated with having anxiety or depression. Our findings demonstrated that prevalence of depression and anxiety was low amongst virally suppressed, long-term antiretroviral-treated HIV-infected individuals. Some key characteristics such as the female sex, poor adherence, poor/fair QOL and EFV exposure are associated with anxiety and depression. These factors can be used to distinguish who would need a more in-depth evaluation for these psychiatric disorders.

Abstract
UNLABELLED Phenomenon: Transient health-related anxiety/hypochondriacal concerns in medical students are well documented. The literature suggests that after studying a particular disease, medical students are likely to consider any symptoms earlier regarded as normal to be signs of the disease they are studying. The aim of this study was to investigate the prevalence of these phenomena and their cognitive and distress aspects among medicals students in Karachi, Pakistan. APPROACH This was an analytical, cross-sectional study. Self-administered questionnaires comprising demographic details, the Short Health Anxiety Inventory, Medical Students' Disease (MSD) Perception Scale, and MSD Distress Scale were distributed to 1st- through 5th-year medical students. FINDINGS In total, 513 medical students (66% female) participated. Their mean age was 21 ± 1.6 years. Three hundred seventy-five students (73%) reported having visited a doctor at least once in the past 6 months. Fifty students (9.9%) admitted to having addictions. The overall prevalence of significant hypochondriacal concerns was 11.9% (61 students). The presence of addiction was associated with a greater likelihood of developing significant health-related anxiety (odds ratio = 3.82, p = .003), 95% confidence interval [1.51, 7.11]. Age, gender, medical school, year of medical school, and visits to the doctor in the previous 6 months were not associated with greater likelihood of developing significant health-related anxiety. Second-year medical students experienced a significantly greater degree of worry (MSD-Distress scale) than 5th-year students (M score = 12.6 ± 4.6 vs. 10.7 ± 4.4, p = .04). Insights: The prevalence of substantial hypochondriacal concerns in medical students in Pakistan was low in comparison to similar studies published in literature. Student health physicians should be aware of the true prevalence of hypochondriacal concerns and behavior and not dismiss legitimate complaints. Educational sessions to counteract this phenomenon can be incorporated into the curriculum of undergraduate medicine. By defining heightened awareness of symptoms as a normal process, different coping techniques can be discussed to help medical students reduce their level of stress.

Abstract
Introduction: Several research finding indicate that nursing care professionals are often faced with situations which may lead to anxiety. The aim of the present research was to determine the prevalence and typical signs of anxiety among nursing employees and nursing students in psychiatric settings. Methods: The Burns Anxiety Inventory was used as an assessment tool to measure anxiety. The research sample consisted of 242 participants. The data collected were processed by the descriptive statistics, Leveneʹs test, the ANOVA statistical test, the Welchʹs t-test, and the post hoc analysis. Pearsonʹs correlation coefficient was used to measure the strength of the association between the variables. Results: The results of the current study show that nearly half of the participants experience anxiety, but the differences were noted as regards their anxiety thoughts (p = 0.039). Anxiety feelings are more prevalent in female students (p = 0.046). Habitual smokers (p = 0.030) and casual smokers (p = 0.020) are more likely to develop anxious feelings and physical signs of anxiety. The anxiety signs are also more pronounced in the respondents with self-assessed lower economic status (p = 0.001) and poor self-rated health (p = 0.0001). Discussion and conclusion: The professionals and students in psychiatric nursing often encounter situations conducive to the development of anxiety. Further studies on the current topic are therefore recommended to design adequate educational programmes to timely recognise anxiety symptoms and to implement mutual and self-help measure.

Abstract
Major depression is thought to originate from maladaptation to adverse events, particularly when impairments occur in mood-related brain regions. Hypothalamus-pituitary-adrenal (HPA) axis is one of the major systems involved in physiological stress response. HPA axis dysfunction and high glucocorticoid concentrations play an important role in the pathogenesis of depression. In addition, astrocytic disability and dysfunction of neurotrophin brain-derived neurotrophin factor (BDNF) greatly influence the development of depression and anxiety disorders. Therefore, we investigated whether depressive-like and anxiety-like behaviors manifest in the absence of glucocorticoid production and circulation in adrenalectomized (ADX) rats after chronic mild stress (CMS) exposure and its potential molecular mechanisms. The results demonstrate that glucocorticoid-controlled rats showed anxiety-like behaviors but not depression-like behaviors after CMS. Molecular and cellular changes included the decreased BDNF in the hippocampus, astrocytic dysfunction with connexin43 (cx43) decreasing and abnormality in gap junction in prefrontal cortex (PFC). Interestingly, we did not find any changes in glucocorticoid receptor (GR) or its chaperone protein FK506 binding protein 51 (FKBP5) expression in the hippocampus or PFC in ADX rats subjected to CMS. In conclusion, the production and circulation of glucocorticoids are one of the contributing factors in the development of depression-like behaviors in response to CMS. In contrast, the effects of CMS on anxiety-like behaviors are independent of the presence of circulating glucocorticoids. Meanwhile, stress decreased GR expression and enhanced FKBP5 expression via higher glucocorticoid exposure. Gap junction dysfunction and changes in BDNF may be associated with anxiety-like behaviors.

Family Smoking, Exposure to Secondhand Smoke at Home and Family Unhappiness in Children. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:14557-70.

Abstract
Tobacco use adversely affects many aspects of well-being and is disliked by non-smokers. However, its association with family happiness is unknown. We investigated the associations of family unhappiness with smoking in family members and secondhand smoke (SHS) exposure at home in Hong Kong children. In a school-based survey in 2012–2013, 1238 primary school students (mean age 8.5 years, standard deviation 0.9; 42.6% boys) reported family smoking, SHS exposure at home and whether their families had any unpleasant experience caused by smoking or SHS in the past 30 days (tobacco-related unpleasant experience), and rated the overall level of happiness in their families (family unhappiness). Multivariable logistic regression was used to study the associations of tobacco-related unpleasant experience and family unhappiness with family smoking and SHS exposure at home. Tobacco-related unpleasant experience and family unhappiness were reported by 27.5% and 16.5% of students. Unpleasant experience was more strongly associated with family smoking than SHS exposure at home. Family unhappiness was associated with both family smoking (odds ratio 2.37; 95% confidence interval 1.51–3.71) and SHS exposure at home (1.82; 1.39–2.40). These results suggest a previously neglected possible impact of tobacco use on family happiness.

Abstract
OBJECTIVES Depressive symptoms have been associated with chronic low-grade inflammation, including elevated neutrophil count. Smokers often have both high neutrophil count and depressive symptoms. Thus, smoking could explain the cross-sectional association between depressive symptoms and neutrophil count. METHODS Total white blood cell count and subtypes, including absolute neutrophil, lymphocyte, monocyte, basophil, and eosinophil counts, were measured in 44,806 participants (28,534 men; mean [standard deviation] age = 38.9 [11.4] years), without a history of chronic disease or current medication. Depressive symptoms were assessed with the Questionnaire of Depression, Second Version, Abridged. Smoking status was self-reported and categorized in five classes. Sex, age, alcohol intake, self-rated health, body mass index, glycemia, physical activity, household composition, occupational status, and education were included as covariates. Associations were examined with general linear models and causal mediation analyses. RESULTS After adjustment for all covariates except smoking, depressive symptoms were positively associated with neutrophil count only (β = 5.83, standard error [SE] = 2.41, p = .014). After further adjustment for a semiquantitative measure of smoking, this association was no longer significant (β = 2.40, SE = 2.36, p = .30). Causal mediation analyses revealed that smoking mediated the association (p < .001), accounting for 57% of its total variance. In contrast, depressive symptoms were negatively associated with lymphocyte count in fully adjusted model only (β = -3.21, SE = 1.11, p = .004). CONCLUSIONS Smoking may confound or mediate the association between depressive symptoms and neutrophil count. These results advocate for including an accurate measure of smoking in future studies addressing this association. When considering the link between depression and inflammation, one should not overlook the noxious effects of smoking.

Abstract
While it is understood that body composition impacts on physical conditions, such as diabetes and cardiovascular disease, it is only now apparent that body composition might play a role in the genesis of common mental disorders, depression and anxiety. Sarcopenia occurs in ageing and comprises a progressive decline in muscle mass, strength and function, leading to frailty, decreased independence and poorer quality of life. This review presents an emerging body of evidence to support the hypothesis that shared pathophysiological pathways for sarcopenia and the common mental disorders constitute links between skeletal muscle and brain function. Contracting skeletal muscle secretes neurotrophic factors that are known to play a role in mood and anxiety, and have the dual role of nourishing neuronal growth and differentiation, while protecting the size and number of motor units in skeletal muscle. Furthermore, skeletal muscle activity has important immune and redox effects that impact behaviour and reduce muscle catabolism.

Abstract
The high prevalence of cigarette smoking and tobacco related morbidity and mortality in people with chronic mental illness is well documented. This review summarizes results from studies of smoking cessation treatments in people with schizophrenia, depression, anxiety disorders, and post-traumatic stress disorder. It also summarizes experimental studies aimed at identifying biopsychosocial mechanisms that underlie the high smoking rates seen in people with these disorders. Research indicates that smokers with chronic mental illness can quit with standard cessation approaches with minimal effects on psychiatric symptoms. Although some studies have noted high relapse rates, longer maintenance on pharmacotherapy reduces rates of relapse without untoward effects on psychiatric symptoms. Similar biopsychosocial mechanisms are thought to be involved in the initiation and persistence of smoking in patients with different disorders. An appreciation of these common factors may aid the development of novel tobacco treatments for people with chronic mental illness. Novel nicotine and tobacco products such as electronic cigarettes and very low nicotine content cigarettes may also be used to improve smoking cessation rates in people with chronic mental illness.

Abstract
SIGNIFICANCE Mitochondria are structurally and biochemically diverse, even within a single type of cell. Protein complexes localized to the inner mitochondrial membrane synthesize ATP by coupling electron transport and oxidative phosphorylation. The organelles produce reactive oxygen species (ROS) from mitochondrial oxygen and ROS can, in turn, alter the function and expression of proteins used for aerobic respiration by post-translational and transcriptional regulation. RECENT ADVANCES New interest is emerging not only into the roles of mitochondria in disease development and progression but also as a target for environmental toxicants. CRITICAL ISSUES Dysregulation of respiration has been linked to cell death and is a major contributor to acute neuronal trauma, peripheral diseases, as well as chronic neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease. FUTURE DIRECTIONS Here, we discuss the mechanisms underlying the sensitivity of the mitochondrial respiratory complexes to redox modulation, as well as examine the effects of environmental contaminants that have well-characterized mitochondrial toxicity. The contaminants discussed in this review are some of the most prevalent and potent environmental contaminants that have been linked to neurological dysfunction, altered cellular respiration, and oxidation.

Abstract
BACKGROUND Bipolar disorder (BD) is commonly comorbid with many medical disorders including atopy, and appears characterized by progressive social, neurobiological, and functional impairment associated with increasing number of episodes and illness duration. Early and late stages of BD may present different biological features and may therefore require different treatment strategies. Consequently, the aim of this study was to evaluate serum levels of eotaxin/CCL11, eotaxin-2/CCL24, IL-2, IL-4, IL-6, IL-10, IL-17, TNF-α, IFNγ, BDNF, TBARS, carbonyl, and GPx in a sample of euthymic patients with BD at early and late stages compared to controls. METHODS Early-stage BD patients, 12 late-stage patients, and 25 controls matched for sex and age were selected. 10mL of peripheral blood was drawn from all subjects by venipuncture. Serum levels of BDNF, TBARS, carbonyl content, glutathione-peroxidase activity (GPx), cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, TNF-α and IFNγ), and chemokines (eotaxin/CCL11 and eotaxin-2/CCL24) were measured. RESULTS There were no demographic differences between patients and controls. No significant differences were found for any of the biomarkers, except chemokine eotaxin/CCL11, whose serum levels were higher in late-stage patients with BD when compared to controls (p=0.022; Mann-Whitney U test). LIMITATIONS Small number of subjects and use of medication may have influenced in our results. CONCLUSION The present study suggests a link between biomarkers of atopy and eosinophil function and bipolar disorder. These findings are also in line with progressive biological changes partially mediated by inflammatory imbalance, a process referred to as neuroprogression.

Abstract
OBJECTIVE To examine the relation between reaction time in adolescence and subsequent symptoms of anxiety and depression and investigate the mediating role of sociodemographic measures, health behaviors, and allostatic load. METHODS Participants were 705 members of the West of Scotland Twenty-07 Study. Choice reaction time was measured at age 16. At age 36 years, anxiety and depression were assessed with the 12-item General Health Questionnaire (GHQ) and the Hospital Anxiety and Depression Scale (HADS), and measurements were made of blood pressure, pulse rate, waist-to-hip ratio, and total and high-density lipoprotein cholesterol, C-reactive protein, albumin, and glycosolated hemoglobin from which allostatic load was calculated. RESULTS In unadjusted models, longer choice reaction time at age 16 years was positively associated with symptoms of anxiety and depression at age 36 years: for a standard deviation increment in choice reaction time, regression coefficients (95% confidence intervals) for logged GHQ score, and square-root-transformed HADS anxiety and depression scores were 0.048 (0.016-0.080), 0.064 (0.009-0.118), and 0.097 (0.032-0.163) respectively. Adjustment for sex, parental social class, GHQ score at age 16 years, health behaviors at age 36 years and allostatic load had little attenuating effect on the association between reaction time and GHQ score, but weakened those between reaction time and the HADS subscales. Part of the effect of reaction time on depression was mediated through allostatic load; this mediating role was of borderline significance after adjustment. CONCLUSIONS Adolescents with slower processing speed may be at increased risk for anxiety and depression. Cumulative allostatic load may partially mediate the relation between processing speed and depression.

Abstract
PURPOSE There is a paucity of research examining the relationship between personality disorders (PDs) and chronic physical comorbidities. Consequently, we investigated associations between individual PDs and PD Clusters, and various common disease groups [cardiovascular disease (CVD), diabetes, arthritis and gastrointestinal disease (GI)] in a nationally representative survey of adults from the United States. METHODS This study utilized pooled data (n = 34,653; ≥20 years) from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. PDs were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule- Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Physical conditions were based on self-reports of being diagnosed by a health professional. Unadjusted and adjusted logistic regressions examined the relationship between PDs and physical conditions. RESULTS After adjustment (sociodemographic factors, past-year mood, anxiety and substance use disorders), Clusters A, B and C PDs were each associated with physical conditions (all p ≤ 0.01). Of the individual PDs, schizoid, schizotypal, narcissistic, borderline and obsessive-compulsive PDs were associated with CVD (all p ≤ 0.01) among younger adults. Paranoid, antisocial, borderline and avoidant PDs and younger adults with schizoid, schizotypal and obsessive-compulsive PDs were each associated with arthritis (all p ≤ 0.01). Significant associations were seen between paranoid, schizoid and schizotypal PDs and diabetes (all p ≤ 0.01). Finally, schizotypal, antisocial, borderline and narcissistic PDs were associated with GI conditions (all p ≤ 0.01). CONCLUSIONS PDs were consistently associated with physical conditions. Investigation of PDs and their relationship with physical health outcomes warrant further research attention as these findings have important clinical implications.

Abstract
Tobacco use in mental health in general and bipolar disorder in particular remains disproportionally common, despite declining smoking rates in the community. Furthermore, interactions between tobacco use and mental health have been shown, indicating the outcomes for those with mental health disorders are impacted by tobacco use. Factors need to be explored and addressed to improve outcomes for those with these disorders and target specific interventions for people with psychiatric illness to cease tobacco smoking. In the context of bipolar disorder, this review explores; the effects of tobacco smoking on symptoms, quality of life, suicidal behavior, the biological interactions between tobacco use and bipolar disorder, the interactions between tobacco smoking and psychiatric medications, rates and factors surrounding tobacco smoking cessation in bipolar disorder and suggests potential directions for research and clinical translation. The importance of this review is to bring together the current understanding of tobacco use in bipolar disorder to highlight the need for specific intervention.

Jamal M, Van der Does W, Penninx BWJH. Effect of variation in BDNF Val(66)Met polymorphism, smoking, and nicotine dependence on symptom severity of depressive and anxiety disorders. Drug Alcohol Depend 2015; 148:150-7. [PMID: 25618300 DOI: 10.1016/j.drugalcdep.2014.12.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2014] [Revised: 12/12/2014] [Accepted: 12/27/2014] [Indexed: 01/05/2023]
Abstract
BACKGROUND Smoking, especially nicotine dependence is associated with more severe symptoms of depression and anxiety disorders. However, the mechanisms underlying this association are unclear. We investigated the effect of brain-derived neurotrophic factor (BDNF) Val(66)Met polymorphism on the severity of depressive and anxiety symptoms in never-smokers, former smokers, non-dependent, and nicotine-dependent smokers with a current diagnosis of depression and/or anxiety. METHODS Patients with depressive or anxiety disorders and with available BDNF Val(66)Met polymorphism data (N=1271) were selected from Netherlands Study of Depression and Anxiety (NESDA). Dependent variables were severity of symptoms. Independent variables were smoking status and BDNF genotype. Age, sex, education, recent negative life events, alcohol use, body mass index, and physical activity were treated as covariates. RESULTS After controlling for covariates, nicotine-dependent smokers had more severe depressive symptoms than non-dependent smokers, former and never-smokers. The latter three groups did not differ in severity of depression. In Val(66)Val carriers, nicotine-dependent smokers had more severe symptoms of depression and anxiety than the other three groups, which were comparable in symptom severity. In Met(66) carriers, there were no group differences on severity of depression and anxiety. Nicotine dependence was the strongest predictor of severity of symptoms only in Val(66)Val carriers. CONCLUSIONS In patients with a current diagnosis of depression or anxiety, the relationship between nicotine dependence and symptom severity may be moderated by BDNF Val(66)Met. These results suggest that inherent genetic differences may be crucial for the worse behavioral outcome of nicotine, and that Val(66)Val carriers may benefit most in mental health from smoking cessation.
