This study aimed to determine the prevalence, beliefs, attitudes, and perceptions of hookah use in a population of undergraduate students at a large public university in Brazil. 

The sample consisted of 1348 undergraduate students aged over 18-year-old. They completed structured questionnaires on demographic information and close-ended questions on the past and current experiences of smoking hookah. The data underwent descriptive analysis and binary logistic regression.

Finally, 1298 valid survey forms were obtained from printed and digital questionnaires. More than half (53.9%) of participants reported having tried hookah at least once, however, only 10.8% reported they had experienced it within the last 30 days. The majority of the studied population presented acceptable beliefs about the harmfulness and addictive capacity of hookah smoking. However, when comparing the perceptions of those who had smoked and those who had never smoked hookah, and also, the perceptions of users and non-users, significant differences were observed. Students who were users or had already tried hookah showed a tendency to underestimate the deleterious effects of this type of smoking.

It could be concluded that hookah smoking was common among Brazilian university students. In addition, preoccupying misperceptions of hookah’s harmfulness and addictive capacity were found. The results showed that the epidemic of hookah smoking, especially among young people, has spread far beyond the Arab world and the Persians. Accordingly, preventive measures must be taken if this population is to be protected from addiction and other serious health problems.

The Yale Food Addiction Scale version 2.0 (YFAS 2.0) is used for the assessment of food addiction (FA). This research intended to evaluate the validity of the Persian translation of the questionnaire and to investigate the psychological properties and the association between FA and anthropometric indices.

In a sample of 473 nonclinical participants, FA, binge eating, and objectively measured anthropometric indices were assessed. Internal consistency, convergent, and validity of the PYFAS 2.0 were examined. Also, the factor structure (confirmatory factor analysis following the 11 diagnostic indicators in addition to the significant distress) and the construct of the scale were evaluated.

The frequencies of mild, moderate, and severe FA based on PYFAS 2.0 were 0.2%, 10%, and 5.5%, respectively. The findings supported a one-factor structure. The confirmatory factor analysis revealed a good construct validity (RMSEA=0.043, χ2=76.38, df=41, χ2 (CMIN)/df=1.862, GFI=0.975, AGFI=0.957, IFI=0.986, RFI=0.958, ECVI=0.319, TLI=0.978). For both the diagnostic and symptom count versions, the PYFAS 2.0 presented acceptable internal consistency (IC) (Kuder-Richardson 20=0.99 and McDonald omega=0.91).

The PYFAS 2.0 was a psychometrically sound instrument in an Iranian non-clinical population. This questionnaire can be used to study FA in Persian non-clinical populations. Future research should study the psychometric characteristics of this scale in high-risk groups.

The study of the smoking and drug use profile of the Tabari cohort enrolment phase, the outcomes of which will be evaluated in the coming years, has proper comprehensiveness. Therefore, the present study aimed to determine the cigarette and drug use status in the population of the Tabari cohort study (TCS).

In this study, the profile of cigarette and drug use in the TCS was evaluated. Data analysis was performed in SPSS version 24 using percentage, mean, and standard deviation, chi-square, and independent t test.

The frequency of daily smoking in the entire population was 9.1%, and the frequencies in men and women were 21.5% and 0.6%, respectively (P<0.001). The frequency of exposure to smoking in the home, at present or in the past, in the entire population was 30.5%, and in the populations living in urban and mountainous areas were 35.4% and 19.8%, respectively (P<0.001). The mean age at first use of cigarettes in the entire population was 20.50±7.61, whereas the mean age of regular smoking was 23.19±8.02. Furthermore, the frequency of experiencing drug abuse in the total population was 6.1%, and the frequencies in men and women were 14.1% and 0.7%, respectively.

According to the results of this study, cigarette smoking and drug use are significant in men, and overall exposure of the Tabari cohort population to tobacco and drugs in the home is high. If effective prevention is not on the agenda, a significant proportion of the future outcomes in this population may be attributable to these risk factors.

Alcohol is a potent substance that causes both acute and chronic changes in almost all neurochemical systems, with the result that heavy drinking can produce serious psychological symptoms including depression, anxiety, and psychoses. It alsoaffects sexual health adversely and causes sexual dysfunction.

This study aimed to find the prevalence and pattern of sexual dysfunction in male patients with alcohol dependence. This cross-sectional study included 100 patients attending psychiatry out patient department (OPD) at a tertiary care center in west India. Informed written consent was taken for collecting socio-demographic and clinical data in a uniform and standard manner. Sexual dysfunction was assessed using a sexual dysfunction checklist, constructed by Arackal and Benegal at the national institute of mental health and neuroscience, Bangalore containing 12 items from the diagnostic criteria for research and ICD-10 classification of mental and behavioral disorders. The Leeds dependence questionnaire was used to assess the severity of alcohol dependence. 

Sexual dysfunction was present in 62% of the patients. Among the patients, 36% had difficulty achieving an erection, 34% had difficulty maintaining an erection, 37% reported premature ejaculation, 7% had delayed ejaculation, 14% reported anorgasmia, 1% had ejaculation with a flaccid penis, 2% had pain during intercourse, 6% were dissatisfied with the frequency ofintercourse, 4% were dissatisfied with their sexual partner, and 7% were dissatisfied with their performance. 

Sexual dysfunction is significantly and positively associated with duration, amount of alcohol consumed per day, and severity of alcohol dependence.

This study aimed to investigate the prevalence of domestic violence (DV) against women who are undergoing methadone maintenance therapy (MMT) and its related risk factors.

This case-control study was conducted on 195 women who were under MMT and a control group consisting of 195 women who were not under it in the city of Zahedan from 22 May to 1 December 2019. Data were collected using a questionnaire for the measurement of violence against women and a sociodemographic questionnaire. In order to analyze the data, the t test, analysis of variance (ANOVA), Pearson’s correlation, and multiple regression analysis were used.

In the case group, 67.2% of participants had experienced DV during the past year. In the control group, the prevalence was 78.5%. The rate of more than one occasion of DV was significantly higher in the group who were under MMT (P<0.05). The most common type of violence was mental abuse. Physical, sexual, and economic abuses were in the next ranks. Important predictors of DV, in order of importance, were: the women’s low educational level, smoking, income level, and polygamy (P<0.05).

MMT is not a risk factor for DV. It seems that the rate of DV against women in Zahedan is very high. The prevalence of recurrent DV in women under MMT was higher than in the general population.

Cigarette and tobacco smoking are closely associated with chronic cardiovascular disease and lung cancer. We aimed to assess the prevalence and 5-year incidence rate (IR) of these two risk factors for cardiovascular diseases in Kerman, southeastern of Iran.

10015 individuals aged 15-80 were recruited to the study between 2014 and 2018 (Kerman coronary artery disease (CAD) risk factors study, KERCADRS) of which 2820 had also participated in the first phase (5 years earlier). We took fasting blood samples and collected demographic information and data on cigarette and water-pipe tobacco smoking (WPTS) through interviews. 

The overall prevalence of cigarette smoking increased from 8.1% in phase1 to 8.8% in phase 2. During the same period, the prevalence of WPTS increased from 10% to 14%, especially in the age groups of 15-45 years. The prevalence of opium dependance was higher among cigarette smokers compared to WPT users. The overall 5-year IR of cigarette and WPTS was 3.6 and 4.65 per 1000 person-years respectively. The highest IRs of cigarette smoking and WPTS were reported in the age group of 15-39 years, and IR of WPTS was higher among women. Obesity, diabetes, and hypertension associated with a reduced IRs of cigarette and WPTS. 

Over the past five years, the prevalence of cigarette smoking has increased slightly, but WPTS has increased more rapidly, especially among women. The highest prevalence of cigarette and WPT smoking was in the age groups of 15-39 years. Smoking is shifting from cigarette smoking to WPTS. Age- and gender-oriented interventions would help correct the unhealthy life style in the community and prevent further smoking-related morbidities and mortalities.

Addiction is a personal and social problem worldwide, and has physical and psychological effects on consumers’ health. Recently, miRNAs have been described as noninvasive biomarkers. Currently, methamphetamine abuse (MA) is mainly diagnosed by chromatography. This study aimed to investigate the expression and diagnostic value of miR-127 and miR-132 in blood samples of patients with MA and non-user healthy controls.

A total of 60 patients with MA (case group) and 60 non-user healthy individuals (control group) were selected from Tabriz, East Azerbaijan, Iran. Peripheral blood was obtained and total RNA was extracted. Then, cDNA synthesis was performed and miR-127 and miR-132 expression was evaluated using real time polymerase chain reaction (PCR) method.

The results of this study demonstrated that miR-127 was significantly lower (0.042-fold change) in patients with MA than in the control group (P<0.05). However, miR-132 was significantly higher (7.1-fold change) in patients with MA than in the control group (P<0.05).

In general, expression of miR-127 and miR-132 may alter in patients with MA. Further studies are needed to identify underlying molecular mechanisms in patients with MA.

Injecting drug use (IDU) is a growing concern in India. This problem may coexist with other psychiatric disorders. The psychiatric comorbidity in IDUrs affects the psychosocial functioning of this population. This study aimed to assess psychiatric comorbidities, psychosocial problems, and global functioning of people who inject opioids.

This cross-sectional study included opioid-dependent individuals with a history of injecting opioids who visited an outpatient clinic for buprenorphine maintenance treatment. The patients were assessed by SCID-I and SCID-II for Axis–I and Axis–II psychiatric disorders, respectively. The diagnosis was confirmed according to DSM-IV-TR. Moreover, the assessment of psychosocial and environmental problems was done according to Axis-IV of DSM-IV. Functioning was assessed using the Global Assessment of Functioning Scale (GAF). Substance use severity was also assessed using Addiction Severity Index (ASI). 

A total of 100 participants were included in the study. All participants were male, and the majority (63%) were in the age range of 18-40 years with the mean age of 36.96 (SD=10.12). Moreover, 76% of the participants had psychiatric comorbidity. Mood disorder (28.95%), anxiety disorder (13.16%), any personality disorder (27.63%) were the most common comorbidities. The results also revealed psychosocial and environmental problems were significantly higher in participants with comorbidity and their global functioning was poor. 

Psychiatric comorbidities are quite common and are associated with various psychosocial and environmental problems. Early identification and interventions for comorbid conditions along with community-based psychosocial rehabilitation should be considered for better outcomes.

Coronary slow flow phenomenon (CSFP) represents a clinical entity with recurrent chest pain leading to living impairment. The present study aimed to investigate whether opium use correlates with primary CSFP.

This study included Iranian patients with suspected coronary artery disease who underwent myocardial perfusion imaging. Coronary blood flow was measured quantitatively using the thrombolysis in myocardial infarction (TIMI) frame count and slow flow was defined as TIMI grade 2 standard deviations. Age and clinical conditions including diabetes mellitus (DM), hypertension (HTN), hyperlipidemia (HLP), history of chest pain, and opium use were recorded. First, the characteristics of the two groups were compared and then the main analyses were conducted to examine the relationship between CSFP and opium use. Data were analyzed using t test and chi-square test via SPSS 25.0. The significance level was set at P<0.05.

This study was conducted on 44 male patients with documented CSFP who had no stenotic lesions and 134 control group male patients who had normal coronary arteries with normal flow. The mean age was similar in the two groups (54.25 vs.52.69, P=0.474). Two groups were significantly different in terms of history of chest pain (P=0.003), but there was no significant difference in HTN (P=0.084), DM (P=0.284), HLP (P=0.183), smoking (P=0.696), and opium use (P=0.107). 

This study indicated that opium use is not associated with primary CSFP.

During recent decades, it has become evident that cigarette smoking has led to an increase in cancer, risk of death, and economic problems or sanitation issues worldwide. Acceptance and commitment therapy (ACT), as a third-wave behavioral therapy, has devoted significant attention to smoking cessation. However, this treatment has been utilized in different formats and protocols. Moreover, addressing its challenges and progress needs examination and integration. Accordingly, the primary aim of this study was to present a narrative review for summarizing and integrating the current data on the effectiveness of ACT on smoking cessation. This study also aimed to investigate the challenges and the future of this field.

The publications from January 1, 2010 to October 9, 2021 were identified by searching MEDLINE, Embase, Scopus, PsycINFO, and Web of Science electronic databases. The search was performed with the following keywords: “Acceptance AND Commitment Therapy” OR “Acceptance” AND “smoking” OR “tobacco” OR “cigarette” OR “smoker” OR “Nicotine”. The inclusion criterion was studies with interventions aimed at reducing smoking cessation in smokers.

A total of 17 articles were analyzed in this study. The results showed that this treatment has significant effectiveness in smoking cessation and psychiatric comorbidities. Moreover, the role of experiential avoidance in smoking cessation was discussed in detail.

ACT is a suitable psychotherapy module for smoking cessation. However, it needs some upgrades regarding technology. To this end, smartphone applications and AVATAR therapy technologies were discussed with their advantages and solvable disadvantages.
