GLOBAL EPIDEMIOLOGY 2024; 8:100148. [PMID: 38983952 PMCID: PMC11231720 DOI: 10.1016/j.gloepi.2024.100148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 06/08/2024] [Accepted: 06/12/2024] [Indexed: 07/11/2024] Open
Abstract
Introduction The present study aims to compare the risk factors, clinical presentation, and severity of coronary artery involvement in young compared to elderly CAD patients to assess the cardiovascular health status for better disease management and control of these specific patients. Methods This registry-based cross-sectional study was conducted using Coronary Angiography and Angioplasty Registry (CAAR) patients in east of Tehran, Iran. The data were extracted from 330 patients with confirmed CAD recorded by the CAAR during July 2021 to August 2023. Results The majority of patients in MCAD (68.2%) and VECAD (80%) were male, while the majority of PCAD patients were female (51.8%). Among PCAD patients, the prevalence of diabetes (38.1%) was higher than in other groups. The presence of IHD history in the father (38.1%) and mother (26.3%) was higher in the VECAD group. The mean total cholesterol, LDL, and LDL/HDL ratio were higher in the VECAD group. Among MCAD group (75.4%) compared to PCAD (58.1%) and VECAD (47.2%) groups, the multi-vessel disease was more common.MCAD patients had the highest median Gensini score compared to PCAD and VECAD patients. Also, in male compared to female the mean Gensini score was higher by 8 units (ß = 8.26, 95%CI = 0.24, 16.28). Conclusion Modifiable risk factors in young CAD patients are common. High LDL-C levels and smoking were the common modifiable CVD risk factors in young patients, indicating the significant role of these traditional risk factors in early atherosclerosis development alongside inheritable risk-factors such as positive family history that were more common in young CAD patients. While, the severity of coronary artery involvement in individuals with MCAD was higher, but the priority of involvement based on the type of vessel was almost the same in all CAD groups.

Abstract
In China, the rate of spicy food consumption is rising, and chili pepper is among the most popular spicy foods consumed nationwide. According to the 'cued overeating' model, visual and olfactory cues of food can lead to changes in physiological responses and increase the likelihood and amount of food intake. However, no studies have explored the role of spicy food cues in cue reactivity among spicy food cravers. The exploratory study aimed to investigate cue-induced physiological responses, subjective cravings, eating behaviors and their associations in spicy food cravers. A group of spicy cravers (n = 59) and a group of age- and sex-matched non-cravers (n = 60) were exposed to food cues that contained or did not contain chili, during which physiological responses and food consumption were measured. The results revealed that spicy food cravers showed increased salivation and heart rate in response to food cues that contained chili compared to cues without chili and consumed significantly more chili oil after chili exposure. For cravers, heart rate during chili exposure was positively correlated with changes in subjective spicy food craving, and increases in subjective spicy food craving during chili exposure positively predicted subsequent chili oil consumption. The current exploratory study confirms the 'cued overeating' model and extends previous findings on food cravings, showing that even though chili peppers can elicit aversive oral burns and pain, they share the same physiological mechanism underlying cue reactivity as other kinds of cravings.

Momentary Influences on Self-Regulation in Two Populations With Health Risk Behaviors: Adults Who Smoke and Adults Who Are Overweight and Have Binge-Eating Disorder. Front Digit Health 2022; 4:798895. [PMID: 35373179 PMCID: PMC8971561 DOI: 10.3389/fdgth.2022.798895] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 02/22/2022] [Indexed: 11/14/2022] Open
Abstract
Introduction Self-regulation has been implicated in health risk behaviors and is a target of many health behavior interventions. Despite most prior research focusing on self-regulation as an individual-level trait, we hypothesize that self-regulation is a time-varying mechanism of health and risk behavior that may be influenced by momentary contexts to a substantial degree. Because most health behaviors (e.g., eating, drinking, smoking) occur in the context of everyday activities, digital technologies may help us better understand and influence these behaviors in real time. Using a momentary self-regulation measure, the current study (which was part of a larger multi-year research project on the science of behavior change) used ecological momentary assessment (EMA) to assess if self-regulation can be engaged and manipulated on a momentary basis in naturalistic, non-laboratory settings. Methods This one-arm, open-label exploratory study prospectively collected momentary data for 14 days from 104 participants who smoked regularly and 81 participants who were overweight and had binge-eating disorder. Four times per day, participants were queried about momentary self-regulation, emotional state, and social and environmental context; recent smoking and exposure to smoking cues (smoking sample only); and recent eating, binge eating, and exposure to binge-eating cues (binge-eating sample only). This study used a novel, momentary self-regulation measure comprised of four subscales: momentary perseverance, momentary sensation seeking, momentary self-judgment, and momentary mindfulness. Participants were also instructed to engage with Laddr, a mobile application that provides evidence-based health behavior change tools via an integrated platform. The association between momentary context and momentary self-regulation was explored via mixed-effects models. Exploratory assessments of whether recent Laddr use (defined as use within 12 h of momentary responses) modified the association between momentary context and momentary self-regulation were performed via mixed-effects models. Results Participants (mean age 35.2; 78% female) in the smoking and binge-eating samples contributed a total of 3,233 and 3,481 momentary questionnaires, respectively. Momentary self-regulation subscales were associated with several momentary contexts, in the combined as well as smoking and binge-eating samples. For example, in the combined sample momentary perseverance was associated with location, positively associated with positive affect, and negatively associated with negative affect, stress, and tiredness. In the smoking sample, momentary perseverance was positively associated with momentary difficulty in accessing cigarettes, caffeine intake, and momentary restraint in smoking, and negatively associated with temptation and urge to smoke. In the binge-eating sample, momentary perseverance was positively associated with difficulty in accessing food and restraint in eating, and negatively associated with urge to binge eat. While recent Laddr use was not associated directly with momentary self-regulation subscales, it did modify several of the contextual associations, including challenging contexts. Conclusions Overall, this study provides preliminary evidence that momentary self-regulation may vary in response to differing momentary contexts in samples from two exemplar populations with risk behaviors. In addition, the Laddr application may modify some of these relationships. These findings demonstrate the possibility of measuring momentary self-regulation in a trans-diagnostic way and assessing the effects of momentary, mobile interventions in context. Health behavior change interventions may consider measuring and targeting momentary self-regulation in addition to trait-level self-regulation to better understand and improve health risk behaviors. This work will be used to inform a later stage of research focused on assessing the transdiagnostic mediating effect of momentary self-regulation on medical regimen adherence and health outcomes.

Abstract
Background There have been little data about the additive effects of coronary risk factors on mortality in diabetic patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI). This study aimed to evaluate the predictors of mortality in diabetic patients presenting with NSTEMI. All patients admitted to Tehran Heart Center (THC) with a confirmed diagnosis of NSTEMI and a history of diabetes mellitus (DM) type 2 between September 2003 and April 2017 were included. Clinical characteristics and paraclinical data such as lipid profiles, creatinine, hemoglobin, and hemoglobin A1C (HbA1C) were evaluated in these patients to predict in-hospital mortality. The approach for model calibration was a logistic regression with the backward elimination method. Results Of a total of 9158 patients with non-ST-segment elevation myocardial infarction, 3133 had diabetes mellitus type 2 and met our criteria to enter the final analysis. In the multivariable analysis, age, chronic obstructive pulmonary disease, and a severely reduced left ventricular ejection fraction (LVEF) significantly increased the rate of in-hospital mortality, whereas mildly and moderately reduced left ventricular ejection fraction did not increase the rate of mortality. Conclusions Age, chronic obstructive pulmonary disease (COPD), and severely reduced LVEF (< 30%) independently increased in-hospital mortality in our diabetic patients with a confirmed diagnosis of NSTEMI. Severely reduced LVEF had the strongest relationship with in-hospital mortality, whereas the mean HbA1C level and the type of DM management exerted no significant effect on in-hospital mortality.

A Randomised Controlled Trial of Inhibitory Control Training for Smoking Cessation: Outcomes, Mediators and Methodological Considerations. Front Psychol 2021; 12:759270. [PMID: 34803842 PMCID: PMC8595834 DOI: 10.3389/fpsyg.2021.759270] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 10/08/2021] [Indexed: 12/03/2022] Open
Abstract
Objective: Inhibitory control training (ICT) has shown promise for improving health behaviours, however, less is known about its mediators of effectiveness. The current paper reports whether ICT reduces smoking-related outcomes such as craving and nicotine dependence, increases motivation to quit and whether reductions in smoking or craving are mediated by response inhibition or a devaluation of smoking stimuli. Method: Adult smokers (minimum 10 cigarettes per day; N = 107, Mage = 46.15 years, 57 female) were randomly allocated to receive 14 days of smoking-specific ICT (named INST; a go/no-go task where participants were trained to not respond to smoking stimuli) or active control training (participants inhibited responding toward neutral stimuli). Participants were followed up to 3-months post-intervention. This trial was preregistered (Australian and New Zealand Clinical Trials Registry ID: ACTRN12617000252314; URL: https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=370204). Results: There were no significant differences between ICT and active control training groups. Specifically, participants in both groups showed significant reductions in craving, nicotine dependence, motivation and a devaluation (reduced evaluation) of smoking-stimuli up to 3-months follow-up compared to baseline. Inhibition and devaluation of smoking stimuli did not act as mediators. Devaluation of smoking stimuli was an independent predictor of smoking and craving at follow-up. Conclusion: Inhibitory control training (ICT) was no more effective at reducing smoking-related outcomes compared to the active control group, however, significant improvements in craving, dependence indicators and evaluation of smoking stimuli were observed across both groups. A return to basic experimental research may be required to understand the most effective ICT approach to support smoking cessation.

Abstract
Background: Acute coronary syndrome (ACS) is one of the main causes of mortality worldwide. We sought to evaluate the correlation between the severity of coronary artery disease (CAD) and conventional coronary artery risk factors in a large cohort of patients with ACS. Methods: This study included all patients admitted to the coronary care unit with a diagnosis of ACS between 2003 and 2017. The patients were divided into 2 groups: 1) unstable angina and 2) myocardial infarction. The aims of this study were to evaluate the effects of the risk factors and extension of coronary artery stenosis in patients with ACS according to the Gensini score. Results: Of a total 40 319 patients who presented with ACS, 18 862 patients (mean age =60.4±11.14 y, male: 67.2%) underwent conventional coronary angiography and met our criteria to enter the final analysis. The median of the Gensini score was 50 (25–88) in the study population. The multivariable analysis showed that age, sex, diabetes mellitus, hypertension, dyslipidemia, family history, cigarette smoking, opium consumption, and myocardial infarction increased the risk of positive Gensini scores. All the aforementioned risk factors, except cigarette smoking and opium consumption, increased the severity of stenosis in those with positive Gensini scores. The strongest relationship was seen vis-à-vis myocardial infarction, sex, and diabetes mellitus. Conclusion: Our findings suggest that age, sex, diabetes mellitus, dyslipidemia, hypertension, family history, and myocardial infarction have significant effects on the severity of CAD. The obesity paradox in relation to CAD should be taken into consideration and needs further investigation in patients with ACS.

Nicotine Tob Res 2020; 22:1788-1794. [PMID: 31907537 DOI: 10.1093/ntr/ntz243] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Accepted: 01/01/2020] [Indexed: 11/13/2022]
Abstract
INTRODUCTION The social and health care costs of smoking are immense. To reduce these costs, several tobacco control policies have been introduced (eg, graphic health warnings [GHWs] on cigarette packs). Previous research has found plain packaging (a homogenized form of packaging), in comparison to branded packaging, effectively increases attention to GHWs using UK packaging prototypes. Past studies have also found that illness sensitivity (IS) protects against health-impairing behaviors. Building on this evidence, the goal of the current study was to assess the effect of packaging type (plain vs. branded), IS level, and their interaction on attention to GHWs on cigarette packages using proposed Canadian prototypes. AIMS AND METHODS We assessed the dwell time and fixations on the GHW component of 40 cigarette pack stimuli (20 branded; 20 plain). Stimuli were presented in random order to 50 smokers (60.8% male; mean age = 33.1; 92.2% daily smokers) using the EyeLink 1000 system. Participants were divided into low IS (n = 25) and high IS (n = 25) groups based on scores on the Illness Sensitivity Index. RESULTS Overall, plain packaging relative to branded packaging increased fixations (but not dwell time) on GHWs. Moreover, low IS (but not high IS) smokers showed more fixations to GHWs on plain versus branded packages. CONCLUSIONS These findings demonstrate that plain packaging is a promising intervention for daily smokers, particularly those low in IS, and contribute evidence in support of impending implementation of plain packaging in Canada. IMPLICATIONS Our findings have three important implications. First, our study provides controlled experimental evidence that plain packaging is a promising intervention for daily smokers. Second, the findings of this study contribute supportive evidence for the impending plain packaging policy in Canada, and can therefore aid in defense against anticipated challenges from the tobacco industry upon its implementation. Third, given its effects in increasing attention to GHWs, plain packaging is an intervention likely to provide smokers enhanced incentive for smoking cessation, particularly among those low in IS who may otherwise be less interested in seeking treatment for tobacco dependence.

Abstract
BACKGROUND Exposure to the use of first, second and third generations of electronic cigarettes (e-cigarettes) elicits the desire to vape and smoke among observers, as well as facilitates smoking behaviour. Given the rapid rise in the popularity of the pod mod JUUL, we examined whether observing the use of this device would elicit similar responses in smokers. Exploratory analyses were also conducted to determine whether JUUL can act as a smoking cue for former smokers. METHODS The sample consisted of 82 young adult participants (62 current smokers and 20 former smokers approximately 1 year smoke free). The study examined their response to observing use of bottled water (control cue) and JUUL (active cue) in a controlled laboratory paradigm. Both cues were delivered by a trained study confederate under the guise of a social interaction task, and participants completed mood and desire and urge surveys precue and postcue exposures. RESULTS In current smokers, exposure to the JUUL cue increased smoking urge and desire for a cigarette, mod/vape pen and JUUL, and two-thirds chose to smoke in the behavioural analogue task. In former smokers, the JUUL cue evoked modest and transient increases in desire for a cigarette and JUUL. CONCLUSIONS The use of JUUL affects the user and elicits responses in observers; this study is the first to demonstrate that exposure to JUUL use may act as a smoking cue and exposure to JUUL use may affect tobacco control efforts.

Abstract
Preclinical studies show that the dopamine D3 receptor (D3R) is involved in the reinstatement of drug seeking and motivation for drugs of abuse. A D3R gene variant, Ser9Gly (rs6280) has been linked to nicotine dependence, yet the mechanisms underlying its involvement in nicotine dependence is unclear. This study investigated the relationship between the Ser9Gly variant and measures of both nicotine reinforcement and cue-elicited craving. Phenotypes of smoking behaviors were assessed in genetically grouped (Glycine vs. No Glycine carriers) current smokers (n = 104, ≥ 10 cigarettes per day). Laboratory measures included a forced choice session (to measure reinforcement of nicotine containing vs. denicotinized cigarettes), and a cue-reactivity session (to measure smoking cues vs. neutral cues elicited craving). The forced choice procedure revealed that subjective ratings were significantly higher in response to nicotinized compared to denicotinized cigarettes; however the Ser9Gly variant did not influence this effect. By comparison, smoking cues elicited greater craving over time compared to neutral cues, and Glycine carriers of the Ser9Gly D3R variant seem to experience a significant blunted cue-elicited craving effect. Results support D3R involvement in nicotine cue reactivity. However, more research is needed to reveal how this gene variant modulates various aspects of nicotine dependence.

Abstract
Introduction This study assessed the impact of expectancy and administration components of acute nicotine inhaler use on craving, heart rate, and smoking behavior in smokers with varying intentions to quit. Methods 47 dependent smokers that differed in self-reported intention to quit (no intention to quit during the next month N = 26 vs. intention to initiate a quit attempt within 2 weeks N = 21) were randomly administered a 4 mg nicotine or nicotine-free inhaler across two sessions. Instructions regarding the inhaler's nicotine content (expect nicotine vs. expect nicotine-free; nicotine expectancy) and flavor (mint vs. citrus) varied across sessions. Craving and heart rate were assessed before and after inhaler administration (two-second inhalations every 10 seconds over 20 minutes). Next, participants were offered an opportunity to self-administer puffs of their preferred tobacco brand during an hour-long progressive ratio task. Results Across participants, nicotine expectancy independently reduced withdrawal related craving (p = .018), but no comparable effects of nicotine administration were evident. In quitting motivated smokers, nicotine expectancy and administration interacted to reduce intention to smoke (p = .040), while nicotine expectancy (p = .047) and administration (p = .025) independently reduced intention to smoke in quitting unmotivated smokers. Blunted heart rate reactivity to nicotine administration was observed in quitting motivated relative to unmotivated smokers (p = .042); however, neither expectancy nor administration impacted smoking behavior in either group (p values > .25). Conclusions Findings indicate that participant quitting intentions moderate acute nicotine replacement therapy responses. In quitting motivated smokers, a combination of pharmacological and psychological factors may be necessary for nicotine replacement therapy to impact craving. Implications Findings from this study demonstrate that motivations to quit smoking moderate subjective and physiological responses to acute nicotine administration and expectancy in dependent cigarette smokers. Quitting motivated smokers showed blunted heart rate reactivity to nicotine administration, suggesting that they may be less sensitive to the rewarding aspects of nicotine consumption. Nicotine administration and expectancy were found to interact to reduce craving in quitting motivated but not in unmotivated smokers, suggesting that pharmacological and psychological factors may be necessary for nicotine replacement therapy to impact craving in smokers who plan to quit.

Abstract
Relapse to smoking after initial abstinence is a major clinical challenge with significant public health consequences. At the brain and behavioral level, those who relapse to tobacco smoking have both greater cue-reactivity and lower inhibitory control than those who remain abstinent. Little is known about neural activation during inhibitory control tasks in the presence of drug-related cues. In the current study, tobacco smokers (SMK; n = 22) and non-smoking controls (CON; n = 19) completed a Go/NoGo task involving smoking cues during a functional magnetic resonance imaging (fMRI) scan. Following the scan session, smokers were required to quit smoking, and maintenance of abstinence was evaluated as part of a 12-week smoking cessation trial. We evaluated pre-cessation brain activity during NoGo trials in smokers who were versus were not able to quit smoking. We then compared fMRI and inhibitory control measures between smokers and non-smokers. We did not find differences between SMK and CON in performance or activation to smoking or neutral cues. However, compared to SMK who relapsed, SMK who attained biochemically-validated abstinence at the end of the smoking cessation trial had greater neural activation in the anterior insula during NoGo trials specifically with smoking-related cues. Results indicate that within SMK, decreased inhibitory control activation during direct exposure to drug-related stimuli may be a marker of difficulty quitting and relapse vulnerability. Smokers and controls showed no differences in performance or activation to smoking or neutral cues. Abstinent smokers compared to relapsers had greater activation in the insula during NoGo trials with smoking-related cues. Within smokers, decreased NoGo activation during exposure to drug-related cues may be a marker of relapse vulnerability.

Abstract
BACKGROUND Smoking cessation aids appear to be limited in their ability to prevent craving triggered by exposure to smoking-associated stimuli; however, the extent to which cue-induced cravings persist following denicotinized or nicotine-containing tobacco smoking is not known. METHODS Thirty (17 male) ⩾12-hour abstinent dependent smokers completed two sessions during which they smoked a nicotine-containing or denicotinized cigarette. Instructions regarding the nicotine content of the cigarette varied across sessions, and all participants were exposed to a neutral cue followed by a smoking cue after cigarette consumption. Craving was assessed before and after cigarette consumption and cue exposure. RESULTS Reduced intentions to smoke were associated with both nicotine expectancy (p<0.05) and nicotine administration (p<0.01), while reduced withdrawal-related craving was uniquely associated with nicotine administration (p<0.05). Smoking-associated stimuli increased craving regardless of nicotine expectancy or administration (p-values<0.001). CONCLUSIONS While both nicotine pharmacology and expectancy appear to contribute to craving reduction associated with acute tobacco smoking, neither smoking-related nicotine administration nor expectation prevents increases in craving following exposure to smoking-associated stimuli. These findings suggest that cue-induced craving may be resistant to various pharmacological and psychological interventions.

Abstract
Introduction The present study aims to contribute to our knowledge on the causes of variations in experienced craving of (ex)smokers. The general idea is tested that when (ex)smokers are exposed to a smoking-cue, their level of craving is determined by the momentary state of mind through which the smoking-cue is interpreted. Methods A cue-reactivity paradigm in temporary abstinent smokers is applied to trigger craving responses under different experimentally induced states of mind. Craving is assessed with a three-item self-report measure. In study 1 (N = 120) a self-affirmation procedure is applied right before abstinent smokers were exposed to their own smoking paraphernalia. In study 2 (N = 140) abstinent smokers received bogus feedback inducing a high or low self-efficacy and strong or weak positive outcome expectations. Results Study 1 showed a significant interaction: When involvement was high, self-affirmation increased the level of craving but when involvement was low self-affirmation lowered craving. Study 2 also showed a significant interaction: Only when the positive outcome expectation of smoking were high, self-efficacy lowered the level of craving. All analyses were controlled for the number of cigarettes smoked a day and number of past quit attempts. Conclusions The present studies provide experimental evidence that levels of craving can be determined by momentary states of mind. This theoretical perspective can be integrated in existing conditioning and social cognitive learning perspectives on craving and substance use.
