RESUMO

INTRODUCTION: A growing literature indicates bidirectional associations between pain and tobacco use. Cigarette smokers are at increased risk for chronic pain, and observational and experimental studies indicate that pain increases motivation to smoke. Tobacco use disorder frequently co-occurs with other substance use disorders, which are also associated with chronic pain vulnerability. Despite evidence that pain significantly predicts smoking and relapse, associations between smoking history/trajectory and changes in pain over the course of treatment have not been characterized. The objective of the study was to determine the association between in-treatment smoking trajectory, pack-years (i.e., number of cigarette packs smoked per day multiplied by smoking duration), pain-related interference in daily activities, and pain intensity over the course of residential treatment. METHODS: In this study, 280 adult smokers in a residential SUD treatment center in North Central Florida completed questionnaires assessing cigarette use, pain intensity, and pain interference at treatment entry and discharge (Mean = 80.3 days, SD = 25.6). Most participants were diagnosed with alcohol use disorder (66.1 %). Opioid (27.9 %) and cannabis use disorders (29.6 %) were also common. Participants were grouped by whether their smoking increased (n = 36), decreased (n = 46), or stayed the same (n = 133) from entry to discharge. RESULTS: Analyses indicated a positive association between pack-years and pain intensity at both baseline (r = 0.185, p = 0.018) and discharge (r = 0.184, p = 0.019). Smoking trajectory was associated with pack-years, with those decreasing smoking having greater pack-years than those sustaining or increasing use [F(2,136) = 8.62, p < 0.01, η2p = 0.114]. Mixed general linear models indicated pain intensity [F(1,274) = 44.15, p < 0.0001, η2p = 0.138] and interference in day-to-day activities [F(1,276) = 31.79, p < 0.0001, η2p = 0.103] decreased significantly over time. However, there was no main effect of smoking trajectory on pain intensity [F(2,212) = 2.051, p = 0.131, η2p = 0.019] or of smoking trajectory by time interaction [F(2, 212) = 1.228, p = 0.295, η2p = 0.011]. CONCLUSIONS: Overall, findings provide evidence that smoking behavior influences pain within the context of residential substance use treatment. Given that pain is associated with urge to use substances and risk of return to use, more consistent and rigorous assessment of pain and proactive pain management is likely to enhance substance use treatment outcomes among people who smoke.

RESUMO

INTRODUCTION: Individuals with serious mental illness (SMI) smoke cigarettes at a much higher rate than the general population, increasing their risk for medical illnesses and mortality. However, individuals with SMI do not get enough support to quit smoking, partially because of concerns from medical providers that reducing smoking may worsen their symptoms or quality of life. METHODS: Veterans with SMI and nicotine dependence (n = 178) completed a 12-week smoking cessation trial (parent trial dates: 2010-2014) including assessments of smoking status, psychiatric symptoms (Brief Psychiatric Rating Scale), and quality of life (Lehman Quality of Life Interview-Short Version) at up to four time points: baseline, post-treatment, three-month follow-up, and 9-month follow-up. Bayesian multilevel modeling estimated the impact of changes in the self-reported number of cigarettes per day in the past seven days on psychiatric symptoms and quality of life. RESULTS: Between subjects, each additional pack of cigarettes smoked per day was associated with a 0.83 point higher score (95%CI: 0.03 to 1.7) on a negative symptoms scale ranging from 0 to 35. Within subjects, each one-pack reduction in the number of cigarettes smoked per day was associated with an improvement of 0.32 (95%CI = 0.12 to 0.54) on the health-related quality of life scale, which ranges from 0 to 7 points. There were no other significant between- or within-subjects effects of smoking on psychiatric symptoms or quality of life. CONCLUSIONS: Individuals with SMI and their providers should pursue smoking cessation without fear of worsening psychiatric symptoms or quality of life.

RESUMO

Young adulthood remains a developmental period in which cigarette smoking initiation and progression to dependence and regular use is common. Moreover, co-use of alcohol and/or cannabis with tobacco is common in this age group and may have detrimental effects on tobacco use rates and cessation outcomes. Although young adults are interested in quitting smoking, achieving abstinence remains difficult, even with evidence-based treatment strategies. Understanding proximal associations between other substance use (e.g., alcohol and cannabis) and smoking may have important treatment implications. This exploratory analysis investigated the role of alcohol and/or cannabis use in contributing to smoking events on the same day or next day among young adults engaged in a smoking cessation and relapse monitoring study. We used ecological momentary assessment (EMA) data from 43 young adults (ages 18-25; 932 observations) who smoked cigarettes daily and agreed to participate in a 5-week study that included a 2-day smoking quit attempt and provision of tobacco treatment in the form of nicotine replacement therapy, brief cessation counseling, and financial incentives for abstinence (incentives were provided only during the 2-day quit attempt). We tested multilevel time-series models of daily associations between alcohol use, cannabis use, and smoking. Consistent with hypotheses, days on which participants were more likely to drink alcohol predicted increased likelihood of smoking the next day (OR = 2.27, p =.003). This effect was significant after controlling for both the one-day lagged effect of smoking (i.e., autoregression) and the concurrent (i.e., same day) effects of drinking and cannabis use. Although there was a positive concurrent effect of cannabis use on smoking (OR = 12.86, p =.003), the one-day lagged effect of cannabis use and the concurrent effect of drinking was not significant, contrary to hypotheses. Results indicate that alcohol use presents a potential threat to successful smoking cessation that extends to the following day. This suggests a risk-window in which treatment could be supplemented with just-in-time interventions and extending the focus on co-use to include this lagged impact on cessation outcomes.

RESUMO

People with schizophrenia (SCZ) have a shorter life expectancy than those without psychiatric conditions. Of note, people with SCZ have high rates of cigarette smoking, physical inactivity, and obesity. These factors all coalesce to contribute to compromised health in this population, with smoking as a primary contributor. Therefore, it is paramount to develop effective smoking cessation strategies for this population. The purpose of this study was to investigate whether walking at a brisk pace, relative to engaging in passive activity, would reduce acute cigarette craving, nicotine withdrawal, and negative affect (NA) among people with SCZ who smoke cigarettes. Using a within-subjects design, twenty participants completed four laboratory sessions with condition sequence counterbalanced: 1) exposure to smoking cues + treadmill walking, 2) exposure to neutral cues + treadmill walking, 3) exposure to smoking cues + passive/sedentary activity, 4) exposure to neutral cues + passive/sedentary activity. Relative to sedentary activity, walking resulted in greater decreases in nicotine withdrawal but did not significantly affect craving or NA. These results did not vary as a function of cue type. These findings suggest that walking may be a helpful strategy to reduce acute nicotine withdrawal symptoms among people with SCZ. However, it should be used in conjunction with other strategies for smoking cessation.

RESUMO

Enhancing motivation to quit among smokers who are not ready for cessation is a key component of several interventions. However, there is a dearth of empirical data about motivational factors and smoking behavior among pre-quit smokers. Here, we examined interactions between approach/avoidance goal motivations and daily abstinence plan (i.e., plans to either continue or abstain from smoking) on daily cigarette use. Current smokers (n = 82; M = 11.4 cigs/day; 46% Female) completed a baseline assessment, including a measure of approach/avoidance motivation [Behavioral Inhibition and Behavioral Activation Scales (BIS/BAS)], followed by 28-days of Ecological Momentary Assessment (EMA). EMA included a morning assessment of abstinence plan, and evening assessment of cigarettes smoked. Multilevel linear models tested interactions between BIS/BAS and abstinence plan on cigarette smoking (defined as percent change from within-subject mean). There was a significant abstinence plan × BIS interaction, F(1, 637) = 6.567, p = .011, and abstinence plan × BAS interaction, F(1, 637) = 6.553, p = .011, on cigarette smoking. High BIS and low BAS were each associated with reduced smoking on abstinence days and increased smoking on non-abstinence days. Modest rates of smoking cessation may be due to the unassisted, spontaneous nature of most quit attempts. Among pre-quit smokers, high behavioral inhibition and low behavioral activation may underlie the ability to intentionally vary smoking levels according to individuals' daily abstinence plans. Future studies should examine how motivational factors during the pre-quit stage may predict long-term smoking cessation in the future. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

During the initial wave of the Coronavirus Disease 2019 (COVID-19) pandemic in the U.S., information was mixed about the relative COVID-19 risks and potential benefits associated with cigarette smoking. Therefore, we sought to understand individual differences in the impact of COVID-19 on cigarette smoking in a sample of adults who reported recent use, with a particular focus on chronic medical conditions likely associated with increased COVID-19 risk. Participants completed an online survey of smoking behavior, demographic variables, medical history, and COVID-19 risk perceptions between July and August 2020 (N = 286). We examined whether medical conditions, COVID-19 risk perceptions and/or demographic characteristics were related to smoking changes in response to the pandemic (i.e., no change, decrease, increase) using multinomial logistical regression. Younger age, higher COVID-19 risk perceptions and Black versus White race were associated with greater odds of decreased smoking compared to no smoking change. Moreover, having at least one chronic medical condition was associated with greater odds of increased smoking relative to no change. The results have important implications for tobacco cessation treatment and preventive healthcare during the ongoing COVID-19 pandemic and other public health threats.

RESUMO

E-cigarette use has been increasing globally over the past decade. Many use e-cigarettes as an alternative or method to quit cigarette smoking, whereas others use these products recreationally. As technology has advanced, many individuals have reported symptoms of dependence on these products and continue to use them beyond achieving abstinence from smoking. Despite individuals reporting interest in quitting, little is known about e-cigarette cessation. This systematic review sought to identify and evaluate all human subjects literature published on the outcome of e-cigarette cessation through September 2021. Of the 79 articles identified, 56 were cross-sectional, 6 were qualitative, 5 were cohort studies, 3 were experimental, 2 were mixed methods, and 7 reported intervention or case studies of e-cigarette cessation. Results showed youth generally had high intent to quit e-cigarettes, whereas results were mixed with adult samples. Youth were motivated to quit e-cigarettes by health concerns, whereas adults were motivated to quit e-cigarettes by cost, lack of satisfaction, and psychologic factors. Adults were more likely to report past e-cigarette quit attempts, most commonly "cold turkey." Few interventions tested strategies for e-cigarette cessation, with a majority targeted for youth. Given the lack of information on e-cigarette cessation, recommendations for future studies are outlined.

RESUMO

INTRODUCTION: Identifying theory-based predictors of electronic nicotine product (ENP) quit attempts and cessation can guide the development of effective vaping cessation interventions, which are currently limited. This study examined predictors of ENP quit attempts and cessation among adult ENP users. METHODS: Using data from wave 3 (W3; 2015-2016) current established ENP users in the Population Assessment of Tobacco and Health study, we used multivariable logistic regression to identify predictors of (i) wave 4 (W4; 2016-2018) quit attempts (unweighted n = 1,135); and (ii) W4 cessation among those who made a quit attempt (unweighted n = 610). Predictors included Social Cognitive Theory (SCT)-based cognitive (interest in quitting, self-efficacy to quit, outcome expectancies, risk perception), behavioral (smoking status, and use of combustibles, non-combustibles, cannabis, and alcohol), and socio-environmental (perceived disapproval, household rules, exposure to advertising) factors. RESULTS: Between W3 and W4, 51.7% of W3 ENP users made a quit attempt. Among those who tried quitting, 68.4% stopped using ENPs. SCT-based predictors of ENP quit attempts included higher interest in quitting ENPs (aOR = 1.18), greater self-efficacy to quit ENPs (aOR = 1.31), and currently using cigarettes (vs non-smoker; aOR = 1.71), non-combustibles (aOR = 2.25), and cannabis (aOR = 1.80). Predictors of ENP cessation included greater self-efficacy to quit ENPs (aOR = 1.33), greater perceived risk of ENPs (aOR = 1.35), and being a current smoker (vs non-smoker; aOR = 3.28). CONCLUSIONS: ENP cessation interventions should address cognitive factors, particularly self-efficacy, as it predicted quit attempts and cessation. Cigarette smoking among dual users should be monitored and addressed to ensure that those who quit using ENPs do not maintain cigarette use.

RESUMO

Objetivo: Evaluar las prácticas clínicas, barreras y facilitadores para dejar de fumar en clínicas de primer nivel de atención en la Ciudad de México. Material y métodos: Diseño de métodos mixtos. Se realizaron encuestas (n=70) y entrevistas semiestructuradas (n=9) a personal de salud involucrado en el servicio de las clínicas para dejar de fumar. Resultados: Datos cuantitativos muestran que el personal médico realizó más que el de enfermería las siguientes prácticas: preguntar a pacientes si fumaban (57,9% vs. 34,5%, p=0,057), si tenían interés en dejar de fumar (65,7% vs. 26,9%, p=0,003), brindar asesoría (54,3% vs. 29,2%, p=0,056) y necesidad de farmacoterapia (21,9% vs. 10%, p=0,285). El personal de enfermería informó más que el personal médico la falta de recursos, farmacoterapia y necesidad de capacitación para asesoría. Los resultados cualitativos muestran como barreras: percepción de falta de motivación para dejar de fumar entre pacientes, falta de tiempo en consulta, largos tiempos de espera para citas y falta de capacitación; y como facilitadores: contar con servicio para dejar de fumar, farmacoterapia sin costo, y equipo multidisciplinario. Conclusiones: Las intervenciones para dejar de fumar se implementan parcialmente. Es necesaria una reestructuración de los servicios, donde el personal de enfermería tenga un mayor rol.(AU)


Objective: To assess the clinical practice, barriers, and facilitators in promoting smoking cessation in primary healthcare clinics in Mexico City. Material and methods: A mixed method design was used. Surveys (n=70) and semi-structured interviews (n=9) were conducted with health personnel involved in smoking cessation clinics. Results: Quantitative data revealed that physicians were more likely than nurses to 1) ask patients if they smoke (57.9% vs 34.5%, p=.057), 2) ask patients if they are interested in quitting smoking (65.7% vs 26.9%, p=.003), 3) provide advice to quit smoking (54.3% vs 29.2%, p=.056), and 4) assess whether pharmacotherapy is needed (21.9% vs 10%, p=.285). Qualitative data showed that nurses were more likely than physicians to report lack of resources to refer patients to smoking cessation services, lack of pharmacotherapy availability, and lack of provider training in smoking cessation. Reported barriers include lack of motivation among patients, lack of time for assessment, long appointment wait times, and lack of training. Reported facilitators include existence of smoking cessation programmes and pharmacotherapy at no cost to the patient, and having a multidisciplinary team. Conclusions: Due to numerous barriers, smoking cessation interventions are partially implemented in primary care clinics in Mexico City. A restructuring of services is necessary, and nurses should be given a more prominent role.(AU)

RESUMO

Smoking prevalence among youth experiencing homelessness (YEH) is three times higher than smoking prevalence among the general population. Many YEH who smoke are interested in quitting smoking, but also report smoking to cope with mental health symptoms. Research on factors that facilitate or impede successful smoking cessation among YEH is limited. This study examined mental health correlates (i.e., anxiety and depression symptoms) of quitting-related factors (i.e., quit attempts, perceived barriers to quitting) and whether smoking to cope moderates these relationships among this vulnerable population. The sample consisted of 77 YEH cigarette smokers between the ages of 18-25 who were interested in quitting. Participants completed a survey assessing various behavioral and cognitive factors related to tobacco use. Analyzing two separate models, hierarchical negative binomial and hierarchical linear regression were used to examine hypothesized correlates of the number of past year quit attempts and perceived barriers to quitting. Smoking to cope moderated the relationships of depression with past year quit attempts and perceived barriers to quitting. Those high in depression and smoking to cope had the fewest number of quit attempts and reported the greatest perceived barriers. Anxiety symptoms were not significantly associated with quit attempts or perceived barriers. Smoking cessation interventions that address using smoking to cope with mental health symptoms may be important for YEH with depression.

RESUMO

INTRODUCTION: Craving is an important contributing factor in cigarette smoking and has been added as a diagnostic criterion for addiction in the DSM-5. Cognitive-behavioral therapy and other treatments that incorporate craving regulation strategies reduce smoking and the likelihood of relapse. Although this finding suggests that the regulation of craving is an important mechanism underlying smoking cessation, whether targeted interventions that train smokers to regulate craving can directly impact real-world smoking behaviors is unclear. METHOD: Across two pilot studies (N = 33; N = 60), we tested whether a brief, computer-delivered training session in the cognitive regulation of craving altered subsequent smoking behaviors in daily life. The study first randomly assigned participants to either a no training (control) group, or one of two Regulation of Craving Training (ROC-T) conditions. Next, all participants came into the lab and those assigned to ROC-T conditions were trained to implement a cognitive strategy to regulate their craving, by either focusing on the negative consequences of smoking, or by distracting themselves. Then, these participants underwent ROC-T during which they practiced using the strategy to regulate their craving during cue exposure. The study subsequently assessed participants' smoking via daily diaries for 3-6 days, and via self-report up to 1-month follow-up. RESULTS: Across both studies, ROC-T conditions were associated with significant reductions in average cigarettes smoked per day, with effects persisting through follow-up. CONCLUSION: These results confirm that the regulation of craving is an important mechanism of smoking cessation, and can be targeted via easily administered training procedures, such as ROC-T.

RESUMO

INTRODUCTION: The competing neurobehavioral decision systems theory conceptualizes addictive behavior, such as cigarette smoking, as arising from the imbalance between stronger impulsive relative to weaker executive decision processes. Working memory trainings may enhance executive decision processes, yet few studies have evaluated its efficacy on substance misuse, with mixed evidence. The current study is the first to evaluate the efficacy of a working memory training on cigarette smoking. We consider the moderating role of delay discounting (DD), or the preference for smaller, immediately available rewards relative to larger, delayed rewards, which has been associated with smoking onset, progression, and resumption. The investigation focuses on individuals living in high-poverty, low-resource environments due high burden of tobacco-related disease they experience. AIMS AND METHODS: The study utilized a subset of data (N = 177 individuals who smoke) generated from a randomized clinical trial that is evaluating the efficacy of working memory training for improving health-related outcomes. Participants were randomized to complete up to 15 sessions of the active, working memory training or a control training. RESULTS: Findings showed that among participants who were randomized to the working memory condition, those with higher rates of baseline DD demonstrated decreases in cigarette smoking (p = .05). Conversely, individuals randomized to the control condition, who had higher rates of baseline DD exhibited increases in cigarette smoking (p = .025). CONCLUSIONS: Results suggest that DD may be an important indicator of working memory training outcomes and a possible approach for effectively targeting treatments in the future. IMPLICATIONS: DD is important indicator of working memory training outcomes on cigarette smoking. The findings suggest the possibility to effectively target treatments considering the impact of DD. Given that rates of DD tend to be higher among individuals from low-resource communities, and that computer-based working memory training programs are relatively low-cost and scalable, these findings suggest this approach may have specific utility for adults at heightened risk for cigarette use.This study was registered with ClinicalTrials.gov (Identifier NCT03501706).

RESUMO

OBJECTIVES: Cannabis use is common among people who use tobacco. However, little is known about the relationship between change in use of tobacco and cannabis over time. We examined the longitudinal associations between use of the two substances in a realworld smoking cessation context. METHODS: This study analyzed data from a 3-month smoking cessation program delivered via Facebook in the San Francisco Bay Area, USA during 2016-2020. The sample included 487 participants who smoked cigarettes ( Mage = 25.4 years old, 39.6% Male, 40.3% White). The regressors (ie, frequency or number of days during the past 30 days using cigarettes, e-cigarettes, and cigars) and the outcome (ie, frequency of cannabis use) were measured at both baseline and 3-month follow-up. Random-effects modeling examined the longitudinal associations between the regressors and the outcome controlling for alcohol use and baseline demographics. RESULTS: Participants who increased (or decreased) their frequency of use of cigarettes (ß = 0.17, 95% confidence interval [CI] = 0.10, 0.24), e-cigarettes (ß = 0.11, 95% CI = 0.05, 0.17), or cigars (ß = 0.19, 95% CI = 0.06, 0.32) also increased (or decreased) their frequency of cannabis use after 3 months. Sexual minority participants (vs heterosexuals) (ß = 2.12, 95% CI = 0.01, 4.24) and those whose education attainment being high school or less (vs higher education) (ß = 3.89, 95% CI = 1.25, 6.53) were more likely to increase their frequency of cannabis use over time. CONCLUSIONS: The findings indicated positive associations between change in use of tobacco and cannabis use. Promoting cessation among people who use tobacco may help to reduce their cannabis use.

RESUMO

Importance: Pregnancy presents an opportunity to engage expectant fathers in smoking cessation, but evidence from randomized clinical trials is scarce. Objective: To evaluate the effectiveness of a proactive, combined intervention for smoking cessation in expectant fathers. Design, Setting, and Participants: This pragmatic randomized clinical trial in prenatal clinics in 7 public hospitals in Hong Kong proactively recruited and enrolled 1053 participants from October 10, 2018, to February 8, 2020. Included male adults were 18 years or older, smoked cigarettes daily in the past 3 months, had partners who were pregnant and nonsmoking in the past 30 days, and had a landline or mobile telephone number for follow-up. These participants were randomized to either the intervention group or the control group. The primary analyses used an intention-to-treat approach. Interventions: The intervention group received brief cessation advice, a 1-week free sample of nicotine replacement therapy (NRT), and active referral to a community-based smoking cessation service. The control group received only brief cessation advice with a leaflet on the hazards of perinatal exposure to tobacco smoke and the toll-free quitline telephone number. Main Outcomes and Measures: The primary outcome was biochemically validated tobacco abstinence at 6 months after intervention initiation defined by an exhaled carbon monoxide level of 3 parts per million or lower. The secondary outcomes included self-reported 24-week continuous abstinence at 6 months after intervention initiation as well as 7-day point prevalence abstinence, use of any NRT, and use of a smoking cessation service at 3 and 6 months after intervention initiation. Results: All 1053 randomized participants were male adults with a mean (SD) age of 33.8 (6.9) years. The retention rate at 6-month follow-up was 80.7%. The primary outcome of biochemically validated tobacco abstinence at 6 months after intervention initiation was significantly higher in the intervention group than in the control group (6.8% [36 of 527 participants] vs 3.6% [19 of 526]; odds ratio [OR], 1.96; 95% CI, 1.11-3.46; P = .02). The main secondary outcomes of self-reported 24-week continuous abstinence at 6 months (OR, 1.87; 95% CI, 1.08-3.23; P = .03) and 7-day point prevalence abstinence at 3 months (OR, 1.48; 95% CI, 1.05-2.09; P = .03) and 6 months (OR, 1.74; 95% CI, 1.29-2.34; P < .001) were also significantly higher in the intervention group. The intervention group had a significantly higher increase in perceived family harmony (score range, 0-10, with a higher score indicating a higher level of harmony) from baseline to 6 months (B = 0.28; 95% CI, 0.063-0.50; P = .01). Conclusions and Relevance: This trial found that combining brief advice with a 1-week sample of NRT and referral to smoking cessation programs nearly doubled the odds that expectant fathers who smoked would achieve validated abstinence compared with providing brief advice alone. The intervention was also effective in promoting family harmony. Trial Registration: ClinicalTrials.gov Identifier: NCT03671707.

RESUMO

Importance: Smoking among individuals with serious mental illness (SMI) represents a major public health problem. Intervening during a psychiatric hospital stay may provide an opportunity to aid engagement in smoking cessation treatment and facilitate success in quitting. Objective: To examine the effectiveness of a multicomponent, sustained care (SusC) smoking cessation intervention in adults with SMI receiving inpatient psychiatric care. Design, Setting, and Participants: The Helping HAND 3 randomized clinical trial compared SusC with usual care (UC) among individuals with SMI who smoked daily and were receiving inpatient psychiatric care in Austin, Texas, in a single hospital. The study was conducted from July 2015 through August 2019. Interventions: The UC intervention involved brief smoking cessation information, self-help materials and advice from the admitting nurse, and an offer to provide nicotine replacement therapy during hospitalization. The SusC intervention included 4 main components designed to facilitate patient engagement with postdischarge smoking cessation resources: (1) inpatient motivational counseling; (2) free transdermal nicotine patches on discharge; (3) an offer of free postdischarge telephone quitline, text-based, and/or web-based smoking cessation counseling, and (4) postdischarge automated interactive voice response calls or text messages. Main Outcomes and Measures: The primary outcome was biochemically verified 7-day point-prevalence abstinence at 6-month follow-up. A secondary outcome was self-reported smoking cessation treatment use at 1, 3, and 6 months after discharge. Results: A total of 353 participants were randomized, of whom 342 were included in analyses (mean [SD] age, 35.8 [12.3] years; 268 White individuals [78.4%]; 280 non-Hispanic individuals [81.9%]; 169 women [49.4%]). They reported smoking a mean (SD) of 16.9 (10.4) cigarettes per day. Participants in the SusC group evidenced significantly higher 6-month follow-up point-prevalence abstinence rates than those in the UC group (8.9% vs 3.5%; adjusted odds ratio, 2.95 [95% CI, 1.24-6.99]; P = .01). The number needed to treat was 18.5 (95% CI, 9.6-306.4). A series of sensitivity analyses confirmed effectiveness. Finally, participants in the SusC group were significantly more likely to report using smoking cessation treatment over the 6 months postdischarge compared with participants in the UC group (74.6% vs 40.5%; relative risk, 1.8 [95% CI, 1.51-2.25]; P < .001). Conclusions and Relevance: The findings of this randomized clinical trial provide evidence for the effectiveness of a scalable, multicomponent intervention in promoting smoking cessation treatment use and smoking abstinence in individuals with SMI following hospital discharge. Trial Registration: ClinicalTrials.gov Identifier: NCT02204956.

RESUMO

Cancer prevention and early detection efforts are central to reducing cancer burden. Herein, we present estimates of cancer risk factors and screening tests in 2018 and 2019 among US adults, with a focus on smoking cessation. Cigarette smoking reached a historic low in 2019 (14.2%) partly because 61.7% (54.9 million) of all persons who had ever smoked had quit. Yet, the quit ratio was <45% among lower-income, uninsured, and Medicaid-insured persons, and was <55% among Black, American Indian/Alaska Native, lower-educated, lesbian, gay or bisexual, and recent immigrant persons, and in 12 of 17 Southern states. Obesity levels remain high (2017-2018: 42.4%) and were disproportionately higher among Black (56.9%) and Hispanic (43.7%) women. HPV vaccination in adolescents 13 to 17 years remains underutilized and over 40% were not up-to-date in 2019. Cancer screening prevalence was suboptimal in 2018 (colorectal cancer ≥50 years: 65.6%; breast ≥45 years: 63.2%; cervical 21-65 years: 83.7%), especially among uninsured adults (colorectal: 29.8%; breast: 31.1%). This snapshot of cancer prevention and early detection measures was mixed, and substantial racial/ethnic and socioeconomic disparities persisted. However, gains could be accelerated with targeted interventions to increase smoking cessation in under-resourced populations, stem the obesity epidemic, and improve screening and HPV vaccination coverage.

RESUMO

BACKGROUND: Modulation of cigarette craving and neuronal activations from nicotine-dependent cigarette smokers using real-time functional MRI (rtfMRI)-based neurofeedback (rtfMRI-NF) has been previously reported. OBJECTIVES: The aim of this study was to evaluate the efficacy of rtfMRI-NF training in reducing cigarette cravings using fMRI data acquired before and after training. METHODS: Treatment-seeking male heavy cigarette smokers (N = 14) were enrolled and randomly assigned to two conditions related to rtfMRI-NF training aiming at resisting the urge to smoke. In one condition, subjects underwent conventional rtfMRI-NF training using neuronal activity as the neurofeedback signal (activity-based) within regions-of-interest (ROIs) implicated in cigarette craving. In another condition, subjects underwent rtfMRI-NF training with additional functional connectivity information included in the neurofeedback signal (functional connectivity-added). Before and after rtfMRI-NF training at each of two visits, participants underwent two fMRI runs with cigarette smoking stimuli and were asked to crave or resist the urge to smoke without neurofeedback. Cigarette craving-related or resistance-related regions were identified using a general linear model followed by paired t-tests and were evaluated using regression analysis on the basis of neuronal activation and subjective craving scores (CRSs). RESULTS: Visual areas were mainly implicated in craving, whereas the superior frontal areas were associated with resistance. The degree of (a) CRS reduction and (b) the correlation between neuronal activation and CRSs were statistically significant (P < 0.05) in the functional connectivity-added neurofeedback group for craving-related ROIs. CONCLUSION: Our study demonstrated the feasibility of altering cigarette craving in craving-related ROIs but not in resistance-related ROIs via rtfMRI-NF training.

RESUMO

The present study was aimed to investigate the phototherapy effect with low-level laser on human bronchial epithelial cells activated by cigarette smoke extract (CSE). Phototherapy has been reported to actuate positively for controlling the generation/release of anti-inflammatory and pro-inflammatory mediators from different cellular type activated by distinct stimuli. It is not known whether the IL-8 and IL-10 release from CSE-stimulated human bronchial epithelium (BEAS) cells can be influenced by phototherapy. Human bronchial epithelial cell (BEAS) line was cultured in a medium with CSE and irradiated (660 nm) at 9 J. Apoptosis index was standardized with Annexin V and the cellular viability was evaluated by MTT. IL-8, IL-10, cAMP, and NF-κB were measured by ELISA as well as the Sp1, JNK, ERK1/2, and p38MAPK. Phototherapy effect was studied in the presence of mithramycin or the inhibitors of JNK or ERK. The IL-8, cAMP, NF-κB, JNK, p38, and ERK1/2 were downregulated by phototherapy. Both the JNK and the ERK inhibitors potentiated the phototherapy effect on IL-8 as well as on cAMP secretion from BEAS. On the contrary, IL-10 and Sp1 were upregulated by phototherapy. The mithramycin blocked the phototherapy effect on IL-10. The results suggest that phototherapy has a dual effect on BEAS cells because it downregulates the IL-8 secretion by interfering with CSE-mediated signaling pathways, and oppositely upregulates the IL-10 secretion through of Sp1 transcription factor. The manuscript provides evidence that the phototherapy can interfere with MAPK signaling via cAMP in order to attenuate the IL-8 secretion from CSE-stimulated BEAS. In addition, the present study showed that phototherapy effect is driven to downregulation of the both the IL-8 and the ROS secretion and at the same time the upregulation of IL-10 secretion. Besides it, the increase of Sp-1 transcription factor was crucial for laser effect in upregulating the IL-10 secretion. The dexamethasone corticoid produces a significant inhibitory effect on IL-8 as well as ROS secretion, but on the other hand, the corticoid blocked the IL-10 secretion. Taking it into consideration, it is reasonable to suggest that the beneficial effect of laser therapy on lung diseases involves its action on unbalance between pro-inflammatory and anti-inflammatory mediators secreted by human bronchial epithelial cells through different signaling pathway.
