Abstract
Background Post-stroke behavioral disinhibition (PSBD) is common in stroke survivors and often presents as impulsive, tactless or vulgar behavior. However, it often remains undiagnosed and thus untreated, even though it can lead to a longer length of stay in a rehabilitation facility. The proposed study will aim to evaluate the clinical, neuropsychological and magnetic resonance imaging (MRI) correlates of PSBD in a cohort of stroke survivors and describe its 12-month course. Methods This prospective cohort study will recruit 237 patients and will be conducted at the Neurology Unit of the Prince of Wales Hospital. The project duration will be 24 months. The patients will be examined by multiple MRI methods, including diffusion-weighted imaging, within 1 week after stroke onset. The patients and their caregivers will receive a detailed assessment at a research clinic at 3, 9 and 15 months after stroke onset (T1, T2 and T3, respectively). The disinhibition subscale of the Frontal Systems Behavior Scale (FrSBe) will be completed by each subject and caregiver, and scores ≥65 will be considered to indicate PSBD.A stepwise logistic regression will be performed to assess the importance of lesions in the regions of interest (ROIs), together with other significant variables identified in the univariate analyses. For patients with PSBD at T1, the FrSBe disinhibition scores will be compared between the groups of patients with and without ROI infarcts, using covariance analysis. The demographic, clinical and MRI variables of remitters and non-remitters will be examined again at T2 and T3 by logistic regression. Discussion This project will be the first MRI study on PSBD in stroke survivors. The results will shed light on the associations of lesions in the orbitofrontal cortex, anterior temporal lobe and subcortical brain structures with the risk of PSBD. The obtained data will advance our understanding of the pathogenesis and clinical course of PSBD in stroke, as well as other neurological conditions. The findings are thus likely to be applicable to the large population of patients with neurological disorders at risk of PSBD and are expected to stimulate further research in this field.

Abstract
OBJECTIVE Suicidal ideation has increased among Latinx individuals in the last decade. Smoking increases the likelihood of suicidal ideation but work on Latinx smokers is minimal. Hazardous drinking and emotion dysregulation could be factors related to suicidal ideation among Latinx smokers, as has been evident in non-Latinx White samples. The current study sought to examine the main and interactive effects of emotion dysregulation and hazardous drinking in relation to suicidal ideation among Latinx daily-smokers. METHODS Participants were 371 Spanish-speaking daily-smokers (58.8% female; Mage = 33.3; SDage = 9.8) recruited from the United States through Qualtrics. We used structural equation modeling (SEM) to test an interactive model of emotion dysregulation and hazardous alcohol consumption in relation to suicidal ideation; we also tested the effect of emotion dysregulation on suicidal ideation as a function of hazardous drinking status. RESULTS Results indicated that latent emotional dysregulation was associated with greater suicidal ideation (p < 0.001); however, hazardous drinking was not related to suicidal ideation (p = 0.186). The interactive term of emotional dysregulation and hazardous drinking was significantly related to suicidal ideation (p = 0.017). Specifically, greater emotion dysregulation was significantly related to suicidal ideation among Latinx smokers who engaged in hazardous drinking (p < 0.001) but not those who did not engage in hazardous drinking (p = 0.123). CONCLUSIONS The current findings suggest that smoking combined with hazardous drinking may be related to increased suicidal ideation among Latinx smokers. Findings are discussed in relation to the potential role of intervention strategies that focus on emotion dysregulation and hazardous drinking among Latinx current daily smokers to mitigate suicidal risk among this established health disparities population.

Abstract
BACKGROUND AND OBJECTIVES Due to their professional characteristics and future career orientation, medical students have a deeper understanding of COVID-19 and enact disease prevention and control measures, which may cause psychological burden. We aimed to assess the psychological impact during the COVID-19 outbreak period(OP) and remission period(RP) among medical students. METHODS We surveyed the medical students in Shantou University Medical College twice-during the OP and the RP, surveying psychological burden of COVID-19 lockdowns and its associated factors. 1069 respondents were recruited in OP and 1511 participants were recruited in RP. We constructed nomograms to predict the risk of psychological burden using risk factors that were screened through univariate analysis of the surveyed data set. RESULTS There was a statistically significant longitudinal increment in psychological burden from OP to RP, and stress as well as cognition in psychological distress were the most dominant ones. Common impact factors of the depression, anxiety and stress included frequency of outdoor activities, mask-wearing adherence, self-perceived unhealthy status and exposure to COVID-19. In addition, the high frequency of handwashing was a protective factor for depression and anxiety. The C-index was 0.67, 0.74 and 0.72 for depression, anxiety and stress, respectively. CONCLUSION The psychological impact of COVID-19 was worse during the RP than during the OP. Thus, it's necessary to continue to emphasize the importance of mental health in medical students during the pandemic and our proposed nomograms can be useful tools for screening high-risk groups for psychological burden risk in medical students.

Abstract
There is increasing evidence that executive functions have significative effects on nicotine abuse. An unresolved challenge for smoking cessation interventions is the detection of factors associated with nicotine use. In order to understand how cognition is affected by nicotine abuse, this study was designed to determine the relationship between years of smoking addiction and several variables of executive functions. The sample was composed of 174 smokers, whose age ranged between 27 and 69 years old (M = 47.44; SD = 8.48). Smokers were assessed at baseline with measures of cognitive inhibition [Go/No Go Task and Five Digit Test (FDT)], updating [Visual Search and Attention Test (VSAT) and Letter-Number Sequencing (WAIS IV)] and shifting [Delay Discounting Task (DDT) and Iowa Gambling Task (IGT)] while the outcome measure was years of smoking. The linear regression and correlation analysis highlighting that the variable which has the strongest association with years of smoking is updating. Multivariate analysis of variance (MANCOVA) followed by Tukey post-hoc tests revealed significant differences such that heavy smoking indicated worse performance than light smoking on updating tasks. These findings report the ability of working memory to predict years of smoking and suggest that cigarette packaging warning may experience a loss of effectiveness in heavy smokers.

Abstract
BACKGROUND Late-life depression is thought to differ in clinical presentation from early-life depression. Particularly, late-life depression is considered to be more characterized by apathy than is early-life depression. Lacking convincing evidence, this study examines the presence and associated socio-demographic/clinical characteristics of apathy in older compared to younger depressed persons. METHODS This cross-sectional study used data from two naturalistic cohort studies, i.e. the Netherlands Study of Depression in Older Persons (NESDO) and the Netherlands Study of Depression and Anxiety (NESDA). These studies included 605 persons (aged 18-93 years) with a major depressive disorder, divided into 217 early-life (< 60 years) and 388 late-life (≥ 60 years) depressed persons. Apathy was considered present if a score of ≥14 on the Apathy Scale. RESULTS Apathy was strongly associated with age: it was more frequently present in persons with late-life depression (74.5%) than in those with early-life depression (53.5%). Independent of age, the following characteristics were associated with the presence of apathy: male gender, low education, use of benzodiazepines, chronic diseases, and more severe depression. Of all potential risk factors, only former and current smoking was associated with the presence of apathy in older depressed persons but not in younger depressed persons (p-value for age interaction = 0.01). LIMITATIONS No causal relationships can be drawn due to the cross-sectional design of the study. CONCLUSIONS In depressed individuals, clinically relevant apathy was more frequently present in older compared to younger persons. Both age groups showed largely the same associated risk factors. Apathy was independently associated with older age, male gender and more severe depression.

Abstract
A considerable proportion of methadone maintenance treatment (MMT) clients have experienced mental health problems (e.g., depression and anxiety), and poor mental health status is associated with HIV-related risk behaviors and treatment drop-out. Resilience is known to be a protective factor for mental health problems but is not studied among MMT clients in China. This study aimed to explore the relationship between resilience and mental health problems (depression, anxiety and stress) among clients of community-based MMT clinics in China. A total of 208 MMT clients completed the face-to-face interview conducted at 4 of 11 MMT clinics in Guangzhou. The Chinese short version of Depression Anxiety Stress Scale (DASS-21) was used to assess the presence of depressive, anxiety and stress symptoms, and the Connor-Davidson Resilience Scale (CD-RISC) was used to measure resilience. Logistic regression models were fit in data analyses. Of all participants, 12.8%, 19.5% and 8.3% had depression, anxiety and stress, respectively. The mean resilience score was 57.6 (SD = 15.9). In the univariate analyses, resilience was negatively associated with two studied mental health problems (depression and anxiety, ORu = 0.96 and 0.96, p < .01). In multivariate models adjusting for both background and other psycho-social factors, resilience was independently associated with probable depression (ORa = 0.97, 95% CI: 0.93-0.99) and anxiety (ORa = 0.96, 95% CI: 0.94-0.99). Resilience was independently associated with depression and anxiety. As resilience is changeable, interventions targeting mental health problems of MMT users should consider resilience as an important part in the designing of such interventions.

Abstract
INTRODUCTION The development of substance use and addiction has been linked to impaired executive function which relies on systems that converge in the prefrontal cortex. This study examined several measures of executive function as predictors of college student alcohol, tobacco, and marijuana use frequency and abuse. METHODS College students (N=321) were administered the Delis-Kaplan Executive Function System (D-KEFS) test battery, the Sensation Seeking Scale V (SSSV), the Frontal Systems Behavioral Scale (FrSBe), the Perceived Stress Scale (PSS), the Michigan Alcohol Screening Test (MAST), the Fagerstrom Test of Nicotine Dependence (FTND). RESULTS Alcohol use frequency was predicted by sensation seeking and FrSBe Disinhibition scores, but the latter only emerged as a unique predictor for binge drinking frequency. Sex and Disinhibition, Apathy and Executive Function FrSBe subscales predicted the frequency of tobacco use. FrSBe scores uniquely predicted tobacco use among daily users. Marijuana use frequency was predicted by sensation seeking, sex, perceived stress, and FrSBe Disinhibition scores, but only sensation seeking predicted daily use after controlling for other variables. FrSBe Disinhibition scores reached levels considered to be clinically significant for frequent binge drinkers and daily marijuana users. Sensation seeking emerged as the predominate predictor of the early stages of alcohol and tobacco related problems. CONCLUSIONS These results suggest ecologically based self-report measures of frontal lobe function and sensation seeking are significant predictors of use frequency among college students and the extent of frontal dysfunction may be clinically significant among some heavy users.

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.

Chronic cigarette smoking is linked with structural alterations in brain regions showing acute nicotinic drug-induced functional modulations. Behav Brain Funct 2016; 12:16. [PMID: 27251183 PMCID: PMC4890474 DOI: 10.1186/s12993-016-0100-5] [Citation(s) in RCA: 76] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2016] [Accepted: 05/14/2016] [Indexed: 12/21/2022] Open
Abstract
Background Whereas acute nicotine administration alters brain function which may, in turn, contribute to enhanced attention and performance, chronic cigarette smoking is linked with regional brain atrophy and poorer cognition. However, results from structural magnetic resonance imaging (MRI) studies comparing smokers versus nonsmokers have been inconsistent and measures of gray matter possess limited ability to inform functional relations or behavioral implications. The purpose of this study was to address these interpretational challenges through meta-analytic techniques in the service of clarifying the impact of chronic smoking on gray matter integrity and more fully contextualizing such structural alterations. Methods We first conducted a coordinate-based meta-analysis of structural MRI studies to identify consistent structural alterations associated with chronic smoking. Subsequently, we conducted two additional meta-analytic assessments to enhance insight into potential functional and behavioral relations. Specifically, we performed a multimodal meta-analytic assessment to test the structural–functional hypothesis that smoking-related structural alterations overlapped those same regions showing acute nicotinic drug-induced functional modulations. Finally, we employed database driven tools to identify pairs of structurally impacted regions that were also functionally related via meta-analytic connectivity modeling, and then delineated behavioral phenomena associated with such functional interactions via behavioral decoding. Results Across studies, smoking was associated with convergent structural decreases in the left insula, right cerebellum, parahippocampus, multiple prefrontal cortex (PFC) regions, and the thalamus. Indicating a structural–functional relation, we observed that smoking-related gray matter decreases overlapped with the acute functional effects of nicotinic agonist administration in the left insula, ventromedial PFC, and mediodorsal thalamus. Suggesting structural-behavioral implications, we observed that the left insula’s task-based, functional interactions with multiple other structurally impacted regions were linked with pain perception, the right cerebellum’s interactions with other regions were associated with overt body movements, interactions between the parahippocampus and thalamus were linked with memory processes, and interactions between medial PFC regions were associated with face processing. Conclusions Collectively, these findings emphasize brain regions (e.g., ventromedial PFC, insula, thalamus) critically linked with cigarette smoking, suggest neuroimaging paradigms warranting additional consideration among smokers (e.g., pain processing), and highlight regions in need of further elucidation in addiction (e.g., cerebellum).

Abstract
The goal of the current analysis is to examine relationships between smoking status and anxiety and depression among adults of Mexican heritage to inform the development of culturally relevant smoking cessations efforts. Mexican heritage residents (N=1,791) of the city of Brownsville, TX, aged 18 years or older, enrolled in the Cameron County Hispanic Cohort, were selected through two stage cluster sampling of randomly selected census tracts from the first and third quartile of SES using Census 2000. Among current smokers, anxiety and depression scores were highest among women who had not completed high school (p<0.05). Former smoking women, but not men, with at least a high school education and former smoking women born in the United States reported higher levels of anxiety and depression than never smoking women. Negative affective states may represent a greater barrier to smoking cessation among women than men.
