The global prevalence of mental health disorders among runaway and homeless youth: A meta-analysis.

A meta-analysis was performed to identify the pooled prevalence of mental health disorders (MHDs) among runaway and homeless youth (RHY). Relevant studies published between December 1, 1985, and October 1, 2023, were identified in the PubMed, Scopus, Web of Science, and Cochrane Library databases. A preliminary screening of 11,266 papers resulted in the inclusion of 101 studies. The pooled-prevalence estimates were obtained using a random-effects model. The findings showed varying lifetime prevalence rates of MHDs: 47% (conduct disorders and psychological distress), 43% (depression), 34% (major depressive disorders), 33% (post-traumatic stress disorder), 27% (personality disorders), 25% (attention-deficit/hyperactivity disorder), 23% (bipolar disorders), 22% (anxiety), 21% (oppositional defiant disorders), 15% (anorexia), 15% (adjustment disorders), 14% (dysthymia), 11% (schizophrenia), 9% (obsessive-compulsive disorders), and 8% (gambling disorder). The current prevalence rates were: 31% (depression), 23% (major depressive disorder), 23% (anxiety), 21% (post-traumatic stress disorder), 16% (attention-deficit/hyperactivity disorder), 15% (bipolar disorder), 13% (personality disorders), 13% (oppositional defiant disorders), 8% (schizophrenia), and 6% (obsessive-compulsive disorders). Regular screening and the implementation of evidence-based treatments and the promotion of integration and coordination between mental health services for adolescent minors and young adults with other service systems are recommended.

The Global Prevalence of Non-suicidal Self-injury, Suicide Behaviors, and Associated Risk Factors Among Runaway and Homeless Youth: A Meta-analysis.

A meta-analysis was performed to determine pooled prevalence of non-suicidal self-injury (NSSI), suicide behaviors (including ideation, attempts), and associated risk factors among runaway and homeless youth (RHY). The databases PubMed, Scopus, Web of Science, and Cochrane Library were searched for relevant studies published from January 1995 to May 2023. Initially, 8465 papers were screened, resulting in 69 included studies. The results showed that among RHY, lifetime prevalence rates were 42% for NSSI, 38% for suicidal ideation, and 27% for suicide attempts. Lifetime prevalence of NSSI and suicide behaviors was higher among adolescent minors (aged 12-17 years) compared to young adults (aged 18-24 years). Also, NSSI and suicide behaviors were associated with having a childhood history of physical and sexual abuse. Developing an impactful community-based suicide prevention campaign tailored for RHY appears warranted. Peer groups and mentorship programs would provide invaluable support for young individuals, as supportive friendships protect against NSSI.

The global distribution and epidemiology of alcohol and drug use among street-involved children and youth: a meta-analysis.

Background: Street-involved children and youth (SICY) who work and live on/of the streets are more likely to inject drugs and engage in psychoactive substance use.Objectives: The present study aimed to identify the prevalence, distribution, sociodemographic determinants, and risk-taking associated with alcohol and drug use among SICY.Methods: Studies published in English related to alcohol and drug use among SICY were searched for from December 1 1985 to July 1 2022, on PubMed, Scopus, Cochrane, and Web of Science.Results: After full-text paper evaluation, 73 studies were included in the meta-analysis. Results indicated that lifetime prevalence rates were 44% (alcohol), 44% (crack), 33% (inhalants), 44% (solvents), 16% (tranquilizer/sedatives), 22% (opioids), and 62% (polysubstance use). The current prevalence rates were 40% (alcohol), 21% (crack), 20% (inhalants), 11% (tranquilizer/sedatives), and 1% (opioids). Also, life-time and current prevalence of alcohol and crack use, current prevalence of tranquilizer/sedative use, and life-time prevalence of polysubstance use were higher among older age groups. Life-time prevalence of tranquilizer/sedative use was lower among older age groups.Conclusions: The high prevalence of using alcohol, crack, and inhalants is a major issue because they are used extensively among different age groups, including minors. Such findings are beneficial for policymakers, health authorities, and professionals in developing programs aimed at minimizing inhalant use and other types of substance use harms among this group. It is important to accurately monitor this risk-exposed population to understand the mechanisms that might help protect them from high-risk substance use.

The Global Distribution and Epidemiology of Psychoactive Substance Use and Injection Drug Use Among Street-Involved Children and Youth: A Meta-Analysis.

Background: Globally, street-involved children and youth (SICY) who work and live on/of the streets are at higher risk of increased psychoactive substances and injecting drug use. Objectives: The present study aimed to identify the prevalence, distribution, sociodemographic factors, and risk-taking behaviors associated with psychoactive substances and injecting drug use among SICY. Methods: Studies in English published from December 1 1985 to July 1 2022, were searched for on PubMed, Scopus, Cochrane, and Web of Science to identify primary studies on psychoactive substances and injecting drug use among SICY. The pooled-prevalence estimates were obtained using a robust fixed-effects model. Results: The most commonly reported life-time and current psychoactive substance was tobacco followed by cannabis, LSD/ecstasy, cocaine, methamphetamine, heroin and injection drug use. The results showed that life-time and current prevalence of methamphetamine and cannabis use, as well as life-time prevalence of cocaine, LSD/ecstasy, heroin, tobacco, and injecting drug use increased as age rose while current prevalence of cocaine and tobacco use decreased as age rose. SICY who were male, homeless, had parents who had died, had history of substance use among family members or best friends, had experienced violence, had casual sex partners, had a history of working in the sex trade, and had unprotected sex were all related to psychoactive substance use and injecting drug use. Conclusions: Research examining this population suffers from lack of studies, therefore, improving the knowledge for interventions aimed at reducing risk behaviors, particularly those related to the transmission of sexually transmitted infections such as HIV is of great importance.

Emergency Department Use, Hospitalization, and Their Sociodemographic Determinants among Patients with Substance-Related Disorders: A Worldwide Systematic Review and Meta-Analysis.

Background: Identifying the determinants of emergency department (ED) use and hospitalization among patients with substance-related disorders (SRD) can help inform healthcare services and case management regarding their unmet health needs and strategies to reduce their acute care. Objectives: The present study aimed to identify sociodemographic characteristics, type of used drug, and risky behaviors associated with ED use and hospitalization among patients with SRD. Methods: Studies in English published from January 1st, 1995 to April 30th, 2022 were searched from PubMed, Scopus, Cochrane Library, and Web of Science to identify primary studies on ED use and hospitalization among patients with SRD. Results: Of the 17,348 outputs found, a total of 39 studies met the eligibility criteria. Higher ED use and hospitalization among patients with SRD were associated with a history of homelessness (ED use: OR = 1.93, 95%CI = 1.32-2.83; hospitalization: OR = 1.53, 95%CI = 1.36-1.73) or of injection drug use (ED use: OR = 1.34, 95%CI = 1.13-1.59; hospitalization: OR = 1.42, 95%CI = 1.20-1.69). Being female (OR = 1.24, 95%CI = 1.14-1.35), using methamphetamine (OR = 1.99, 95%CI = 1.24-3.21) and tobacco (OR = 1.25, 95%CI = 1.11-1.42), having HIV (OR = 1.70, 95%CI = 1.47-1.96), a history of incarceration (OR = 1.90, 95%CI = 1.27-2.85) and injury (OR = 2.62, 95%CI = 1.08-6.35) increased ED use only, while having age over 30 years (OR = 1.40, 95%CI = 1.08-1.81) and using cocaine (OR = 1.60, 95%CI = 1.32-1.95) increased hospitalization only among patients with SRD. Conclusions: The finding outline the necessity of developing outreach program and primary care referral for patients with SRD. Establishing a harm reduction program, incorporating needle/syringe exchange programs, and safe injection training with the aim of declining ED use and hospitalization, is likely be another beneficial strategy for patients with SRD.

Suicidal Behaviors and Associated Factors Among Individuals with Gambling Disorders: A Meta-Analysis.

The risk for suicidal behaviors including suicide ideations and attempts among individuals with gambling disorder (IWGDs) is high compared to the general population. Little is known about the interplay of mood disorders, alcohol use disorders, and suicidal behaviors among IWGDs. The study aimed to determine the prevalence, sociodemographic characteristics, risky behaviors, mental health disorders, and alcohol use disorders associated with suicide behaviors among IWGDs. Studies published between January 1 1995 and September 1 2022 were obtained from following databases: PubMed, Scopus, Web of Science and Cochrane Library databases. PECOS (population, exposures, comparison, outcome, and study design) criteria were used for selecting studies. The Newcastle-Ottawa Scale (NOS) was used for assessing risk of bias and rated each study in terms of exposure, outcome, and comparability. After initial assessment of 10,243 papers, a total of 39 studies met the eligibility criteria. Among IWGDs, the findings indicated a life-time pooled prevalence rate of 31% for suicide ideations (95% CI, 23-39%), 17% for suicide plans (95% CI, 0-34%), and 16% for suicide attempts (95% CI, 12-20%). Generally, suicide ideations among IWGDs were associated with having any financial debt and having chronic physical illnesses, as well as experiencing depression, mood disorders, and alcohol use disorders. Suicide attempts among IWGDs were associated with being older and having a childhood history of sexual abuse, as well as experiencing depression, mood disorders and alcohol use disorders. Interventions can help to facilitate seeking support among IWGDs by de-stigmatizing mental health disorders as well as improving the quality of care presented to individuals with psychiatric conditions.

Suicidal Behaviors and Risk Taking Among Homeless Individuals: A Systematic Review and Meta-Analysis.

The present systematic review and meta-analysis study aimed to determine sociodemographic characteristics, risky behaviors, mental health disorders, and substance use disorders associated with suicide behaviors including suicidal ideation and suicide attempts among homeless individuals. PubMed, Scopus, Web of Science, and Cochrane Library databases were searched to identify the relevant studies published between January 1, 1995 and November 1, 2022. After initial evaluation of 9,094 papers, a total of 23 studies met the eligibility criteria. Results of the present study showed that chronic physical illnesses, violent behaviors, mood and psychotic disorders, and substance use disorders were significantly associated with both suicidal ideation and suicide attempts, while being older, having a history of physical abuse, and having mood and post-traumatic stress disorders were associated with suicide attempts only. The present study's findings suggest a crucial need for facilitating access to mental healthcare plans and promoting mental healthcare seeking among homeless individuals.

The effect of telephone counseling and follow-up on empowering women with breast cancer undergoing chemotherapy.

Empowering women with breast cancer leads to better adaptation to diagnosis and treatment, and reduces the symptoms of cancer. The purpose of the researchers is to determine the effect of a telephone counseling and follow-up program on empowerment of women with breast cancer undergoing chemotherapy. We used a non-randomized clinical trial design. Researchers applied the telephone counseling and follow-up to the intervention group for 8 weeks. At the end of study, the intervention group showed improvement in measures of cancer functional management and breast cancer specific function, along with satisfaction with the decision, general symptoms of cancer and specific symptoms of breast cancer.

"Association between dietary inflammatory index (DII) and risk of irritable bowel syndrome: a case-control study".

BACKGROUND: Pathophysiology of IBS is not well recognized; however, several studies have shown the possible relationship between diet and risk of IBS. We assessed the ability of the dietary inflammatory index (DII) to predict the risk of IBS. METHODS: The subjects were 155 IBS cases and 310 age- and sex-matched healthy controls (aged ≥18 years). The participants were recruited from June, 2019 to March, 2020. IBS was recognized using the Rome IV criteria. DII score was computed based on dietary intake using a 168-item FFQ. The DII score was calculated based on energy-adjusted amounts of nutrients using residual method. Logistic regression models were used to estimate multivariable odds ratios (ORs). RESULTS: The mean DII score was significantly higher among IBS patients in comparison to healthy controls (0.78 ± 2.22 vs. - 0.39 ± 2.27). In crude model, increase in DII as continuous variable was associated with a significant increase in the risk of IBS (OR (95% CI): 1.26 (1.1-15.38)). Furthermore, the association remained significant even after adjusting for age and sex (OR (95% CI): 1.28 (1.1-17.41)) and after multivariate adjustment (OR (95% CI): 1.38 (1.2-1.56)). In crude, age and sex adjusted and multivariate-adjusted models subjects in fourth quartile of DII had higher OR in comparison to subjects in first quartile. CONCLUSIONS: This study showed a possible positive association between a pro-inflammatory diet and the risk of IBS. Thus, encouraging intake of more anti-inflammatory dietary factors and reducing intake of pro-inflammatory factors may be a strategy for reducing risk of IBS.

The Association of Oral Health Status and socio-economic determinants with Oral Health-Related Quality of Life among the elderly: A systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to determine the relationship between poor Oral Health-Related Quality of Life (OHRQoL) and oral health determinants (eg being 75 years of age or greater, marital status, smoking status, denture wearing, depression, low educational level (≤8th grade), poor general health, caries history, tooth-induced pain, decayed, missing filled teeth (DMFT) scores and periodontal diseases) among the elderly. METHODS: Formal search strategies in PubMed, Scopus, Cochrane and Web of Science were performed to identify studies in English published before 1 December 2019. We assessed the impacts of the oral health determinants including being 75 years of age or greater, marital status, smoking status, denture wearing, depression, low educational level (≤8th grade), poor general health, caries history, tooth-induced pain, DMFT scores and periodontal diseases) on OHRQoL among elderly individuals. The data were analysed using Stata 12.0 software. RESULTS: In total, 19 publications met the inclusion criteria of this meta-analysis. Findings indicate a positive association between low educational level (ie ≤8th grade), marital status, depression, smoking status, denture wearing, poor general health, tooth-induced pain, periodontal diseases and poor OHRQoL among the elderly. We also observed a negative association between DMFT, being older than 75 years of age on poor OHRQoL among the elderly. CONCLUSIONS: This review identified that several oral health determinants were associated with poor OHRQoL. The efficacy of preventive measures and the economic aspects of tooth replacement approaches should be explored in the future. Developing oral healthcare plans and policies with the specific aim of improving OHRQoL among this group is essential.

Dental caries and periodontal disease among people who use drugs: a systematic review and meta-analysis.

BACKGROUND: The aim of our study was to perform a systematic review of the literature and meta-analysis in order to investigate relationship between drug use and oral health. METHODS: We searched for studies in English published before July 1, 2019 on PsycINFO, PubMed, SciELO, Scopus, and Web of Science. We assessed the relationship between drug use (methamphetamines, heroin; opiates; crack, cocaine and cannabis as dependent variables) and reported tooth loss, periodontal disease, or decayed, missing, and filled teeth index as an independent variable. The data were analyzed using Stata 12.0 software. RESULTS: We initially identified 1836 potential articles (with 1100 duplicates) and screened the remaining 736 titles and abstracts, comprising 54 studies. In the next step, we evaluated the full-texts; 44 studies were excluded, accordingly. In total, we included 10 publications in the meta-analysis. Drug type was associated with periodontal disease (OR 1.44; 95% CI 0.8-2.6) and pooled estimates showed that type of drug used increased the odds of the number of decayed, missed and filled teeth (DMFT) (OR 4.11; 95% CI 2.07-8.15) respectively. CONCLUSIONS: The analytical challenges of segregating the impact of individual drug types on oral health diseases mean that investigations on the direct relationship between oral health status and drug use are limited. Developing programs to improve potential confounding with various substances and addressing the dental health needs of people who use drugs is vital if we are to improve their overall quality of life.

Estimation of the basic reproduction number (𝑠0) of the COVID-19 epidemic in Iran.

Background: Estimation of the basic reproduction number of an infectious disease is an important issue for controlling the infection. Here, we aimed to estimate the basic reproduction number (𝑅0) of COVID-19 in Iran. Methods: To estimate 𝑅0 in Iran and Tehran, the capital, we used 3 different methods: exponential growth rate, maximum likelihood, and Bayesian time-dependent. Daily number of confirmed cases and serial intervals with a mean of 4.27 days and a standard deviation of 3.44 days with gamma distribution were used. Sensitivity analysis was performed to show the importance of generation time in estimating 𝑅0. Results: The epidemic was in its exponential growth 11 days after the beginning of the epidemic (Feb 19, 2020) with doubling time of 1.74 (CI: 1.58-1.93) days in Iran and 1.83 (CI: 1.39-2.71) in Tehran. Nationwide, the value of 𝑅0 from February 19 to 29 using exponential growth method, maximum likelihood, and Bayesian time-dependent methods was 4.70 (95% CI: 4.23-5.23), 3.90 (95% CI: 3.47- 4.36), and 3.23 (95% CI: 2.94-3.51), respectively. In addition, in Tehran, 𝑅0 was 5.14 (95% CI: 4.15-6.37), 4.20 (95% CI: 3.38-5.14), and 3.94 (95% CI: 3.45-4.40) for exponential growth, maximum likelihood, and Bayesian time-dependent methods, respectively. Bayesian time dependent methods usually provide less biased estimates. The results of sensitivity analyses demonstrated that changes in the mean generation time affect estimates of 𝑅0. Conclusion: The estimate of 𝑅0 for the COVID-19 ranged from 3.94 to 5.14 in Tehran and from 3.23 to 4.70 in nationwide using different methods, which were significantly larger than 1, indicating the potential of COVID-19 to cause an outbreak.

Effect of L-carnitine on liver enzymes and biochemical factors in hepatic encephalopathy: A systematic review and meta-analysis.

BACKGROUND AND AIMS: We aimed to investigate the effect of L-carnitine on biochemical factors including ammonia, bilirubin, albumin, alanine aminotransferase, aspartate aminotransferase (AST), blood urea nitrogen (BUN), and creatinine (Cr) in patients with hepatic encephalopathy (HE). METHODS: A systematic search was carried out in Web of Science, PubMed, Scopus, and Cochrane Library databases to find articles related to the effect of L-carnitine supplementation in patients with HE, up to 7 February 2019. There was no language and time limitation. Meta-analyses were carried out using both the random and fixed effects models where appropriate, and I2 index was used to evaluate the heterogeneity. RESULTS: Search yielded 3462 publications. Nine randomized clinical trials with 779 patients were eligible. L-carnitine supplementation significantly reduced blood levels of ammonia. Furthermore, our results indicated that L-carnitine supplementation significantly reduced blood levels of bilirubin, AST, BUN, and Cr in patients with HE. Subgroup analysis demonstrated that L-carnitine significantly reduced ammonia in patients with all the ages, long and short duration of the supplementation, doses less or higher than 4000 mg/day, any route of treatment (intravenous or oral), and in patients with any grade of the symptoms of HE. Moreover, we found that L-carnitine significantly increased circulating levels of albumin in HE patients. CONCLUSIONS: Present systematic review and meta-analysis revealed that L-carnitine supplementation significantly reduced blood levels of ammonia, bilirubin, AST, BUN, and Cr in HE patients. Moreover, we found that L-carnitine significantly increased circulating levels of albumin. However, further large-scale randomized clinical trials are needed.

Association of screen time and physical activity with health-related quality of life in Iranian children and adolescents.

BACKGROUND: Health-related quality of life (HRQoL) is a multidimensional concept with significant effects and children and adolescence; while physical activity (PA) and screen time (ST) have been suggested as its probable predictors. Present study aims to investigate the association of PA, ST and their combination, with HRQoL in a nationally-representative sample of Iranian children and adolescents. METHODS: As for the estimated sample size, 25,000 students aged 6-18 years were selected via multi-stage cluster sampling from 30 provinces of Iran. Sociodemographic data was obtained by using the questionnaire of the World Health Organization-Global school based student health survey (GSHS). Persian Pediatric Quality of Life inventory (PedsQL) and Physical Activity Questionnaire for the pediatric age group (PAQ-A) were applied for evaluating HRQoL and PA, respectively. PA scores 1-1.9 and 2-5 were respectively considered as low and high PA. The average duration of time spent on watching TV and leisure time computer use were considered as ST behaviors. ST of less than 2 h was considered low. RESULTS: Out of 25,000 invited individuals, 23,043 students (mean age: 12.5) completed the study (response rate: 92.17%). In linear regression models, ST duration had significant inverse association with total QoL (ß: - 0.49, p < 0.05). PA showed positive significant associations with HRQoL total score (ß: 1.8, p < 0.05). Joint association of PA and ST revealed the strongest association of "high PA-low ST" category with total HRQoL (ß: 2.2, p < 0.05); while "high PA-high ST" showed better total HRQoL score (ß: 1.3) compared to "low PA-low ST" subgroup. CONCLUSION: Both PA and ST are significantly and independently associated with HRQoL in Iranian children and adolescents; while the adverse effect of prolonged ST could be diminished by a high PA.

Association of adolescents' weight status with life satisfaction: role of self, peers, family and school perception; the CASPIAN-IV Study.

BACKGROUND: Although many public health programs have focused on prevention and control of obesity, their efficacy mostly depends on personal factors including perception of weight and personal understanding of the concept of being overweight. This study aims to investigate the association of adolescent's weight status with life satisfaction and explore the role of self, peers, family and school perception in this association. METHODS: Data were obtained from the fourth school-based survey entitled "Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease" (CASPIAN) Study. This survey was conducted among 14,880 urban and rural students aged 6-18 years. Two sets of valid and reliable questionnaire obtained from Global School Health Survey (GSHS) were completed by students and their parents. The students' questionnaire had several questions including life satisfaction and the perception of weight, peers, family and school. RESULTS: The study had a participation rate of 90.6% including 50.8% boys and 76% urban residents. Significant differences existed in Body Mass Index (BMI) and in perception of weight among girls and boys. Moreover, the prevalence of depression and being bullied were higher among girls and boys, respectively. Significant association was documented between life satisfaction and all variables including perception of weight, peers, family and school; the only exception was for BMI (P<0.05). In addition, students with normal weight had significantly higher life satisfaction in comparison with their obese counterparts (P<0.05). CONCLUSIONS: The present study documented significant association between life satisfaction and perception of self, peer, family and school with the exception of BMI in both genders.

The impact of ambient temperature on acute myocardial infarction admissions in Tehran, Iran.

While the effect of temperature on risk of cardiovascular events is well documented, few studies report evidence from the Middle East. In this study, we investigate the short-term effect of ambient temperature on admissions for acute myocardial infarction (AMI) in Tehran, Iran. We used a case-crossover design combined with a distributed lag non-linear model to examine nonlinear and delayed associations between ambient temperature and AMI admissions from 2013 to 2016. We also examined hot and cold effects on AMI admission by gender and age categories (≤ 65 years old and > 65 years old). Both hot and cold temperatures increased the risk of AMI admissions. Effects of high temperature appeared immediately on the current day and lasted for 3 days, whereas cold effects became apparent after 2 days and persisted for about 8 days. The early acute increase in risk associated with high temperature was followed by a deficit, thus suggesting evidence of a harvesting effect. In additions, males and those aged ≤ 65 years old were more vulnerable to high temperatures.

Trends in health burden of untreated water and insanitary environments in Iran, 1990-2010: Findings from the global burden of disease study 2010.

Background: Water, sanitation and hygiene have a very important role in public health. Poor sanitation is the cause of water contamination, which causes many types of diseases. The aim of this paper was to present the attributable death and disability adjusted life year (DALYs) of untreated water and insanitary environments from 1990 to 2010 in Iran. Methods: In the Global Burden of Disease 2010 study, using the comparative risk assessment, the proportion of death and DALYs attributable to untreated water source and insanitary environment has been calculated in 1990 to 2010. The certain outcomes were intestinal infectious diseases for both untreated water source and insanitary environments. Estimated attributable deaths and DALYs were reported with 95% uncertainty interval (UI). Results: DALY number for untreated water source and insanitary environments was 5838 (95% UI: 198- 14837) in 1990, which decreased to 326 (95% UI: 9-863) in 2010 and the percent of decrease was 94.42%. In addition, DALY rate was 5667 (95% UI: 192-14402) DALY per 100,000 in 1990, which decreased to 453 (95% UI: 13-1199) DALY per 100,000 in 2010 and the percent of the reduction was 92.01%. The greatest percentage of decrease in the attributed number of deaths was also found in the late neonatal age group (95.45%). Conclusion: A significant decrease has occurred in a number of DALYs and deaths between 1990 and 2010, which was attributed to the development of new water systems and environmental sanitations in Iran.

Joint Association of Active and Passive Smoking with Psychiatric Distress and Violence Behaviors in a Representative Sample of Iranian Children and Adolescents: the CASPIAN-IV Study.

BACKGROUND: Mental health and smoking have been receiving increasing attention in adolescents all over the world. Although some studies have assessed the independent association of active/passive smoking with mental health, joint association of active and passive smoking with mental health remains unclear. PURPOSE: This study was designed to evaluate the joint association of smoking status (active and passive smoking) with psychiatric distress and violent behaviors in Iranian children and adolescents. METHOD: In this national survey, 13,486 students, aged 6-18 years, living in rural and urban areas of 30 provinces of Iran were selected via multistage, cluster sampling method. Psychiatric distress (including worthless, angriness, worrying, insomnia, confusion, depression, and anxiety), violence behaviors (including bullying, victim, and physical fight), and smoking status (nonsmoker, only passive smoker, only active smoker, and active and passive smoker) were assessed. The questionnaire was prepared based on the World Health Organization Global School-based Student Health Survey (WHO-GSHS). Data were analyzed by the Stata package. RESULTS: Psychiatric distress and violent behaviors had linearly positive association with smoking status (p trend < 0.001). Compared to "nonsmoker" group, participants who were exposed to passive smoking besides active tobacco use were at increased risk of having angriness (odds ratio (OR) 2.55, 95 % confidence interval (CI) 1.86-3.48), worrying (OR 1.66, 95 % CI 1.24-2.20), and anxiety (OR 1.99, 95 % CI 1.52-2.61) and victim (OR 1.77, 95 % CI 1.34-2.33) and bully behaviors (OR 3.08, 95 % CI 2.33-4.07). CONCLUSION: The current findings suggest that active and passive tobacco smoking has synergistic effect on psychiatric distress. Since majority of smokers with psychiatric distress do not receive mental health services or counseling on smoking, strategies to address mental health problems and smoking prevention should be included as a part of school health services.

Predictors of emotional intelligence among family caregivers of cancer patients: A cross-sectional study.

BACKGROUND: Family caregivers of cancer patients must have strong emotional intelligence skills essential for understanding one's and others' feelings and learning how to cope. OBJECTIVES: The present study aims to determine the predictive factors of emotional intelligence and its relationship with spiritual intelligence, coping, and knowledge and experience about pain among family caregivers of cancer patients in Iran. METHODS: A cross-sectional, descriptive study was conducted in 2020-2021. Two hundred twenty-six family caregivers of cancer patients participated in this study. The data collection tools were Wong and Law's emotional intelligence, King's spiritual intelligence, Brief Cope, and the family pain questionnaire. Following determining the variables' correlation, linear regression was carried out. RESULTS: Emotional intelligence had a significant correlation with age (r = 0.20, p = .003), academic degree (r = 0.15, p = .032), duration of care (r = 0.15, p = .032), and spiritual intelligence (r = 0.30, p < .001). The regression model accounted for 12.4% of the variance in emotional intelligence; age (ß = 0.16, p < .021) and spiritual intelligence (ß = 0.26, p < .001) were significant explanatory variables. CONCLUSIONS: Emotional intelligence is correlated with age, academic degree, duration of care, and spiritual intelligence, but only age and spiritual intelligence were found to be predictive factors for emotional intelligence in the family caregivers of cancer patients.

Evaluating the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment: A triple-blinded, randomized, placebo-controlled trial.

INTRODUCTION: Mild cognitive impairment is the middle level of natural cognitive impairment during primary steps of dementia. There are a few studies about improving the cognitive performance and sleep quality in patients with a limited dementia. So, this study was conducted to evaluate the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment. MATERIALS AND METHODS: In this study, 62 patients with mild cognitive impairment were categorized into two groups of control and intervention. The intervention group received one pill of 160 mg Bacopa monnieri extract in 2 months, and the control group received a pill containing starch powder. The cognitive impairment and sleep quality was assessed using a questionnaire containing demographic information, Montreal Cognitive Assessment, and the Pittsburg Sleep Quality Index in three time-points of before the study, one months after the intervention and 2 months after the intervention (the end of study). RESULTS: The results showed no statistically significant difference between two groups in all three time-points in overall cognitive performance score and its 6 parameters (P > 0.05). While in the field of attention at the end of the first month (P = 0.033) and the end of the second month (P = 0.004), it was significant difference between the study groups. Also, in the field of verbal fluency at the end of the second month, this difference was significant (P = 0.003). The cognitive performance overall score showed no significant difference between two groups in first (P = 0.939) and second time-points (P = 0.661), although it was significant at third time-point (P = 0.029). There was no statistically significant difference between two groups in all time-points for sleep quality overall score (P > 0.05). CONCLUSION: The results showed that Bacopa monnieri can improve the cognitive performance overall score and some of its parameters, but it had no effect on sleep quality.
