Introduction: Preparedness a social behavior with public trust the prerequisite for proper social functioning can reduce disaster sufferings. The aim of this study was to determine the public trust, preparedness, and the influencing factors regarding the COVID-19 pandemic situation in Iran. Methods: This online cross-sectional study conducted on Tehran residents (≥18 years) during the fifth epidemic wave. The tool designed to assess the intention to prepare, public trust, and the subscales. T-test used to compare the means and linear regression to determine the factors influencing on the outcomes. Results: About 26.5% of 407 participants (mean age standard deviation: 40.8 (12.8) years) showed low trust. The mean levels of total trust (P = 0.011), general trust (P = 0.048), and trust to managing authorities (P = 0.018) were significantly lower in men. Adjusted to confounding variables, total trust was lower in men (ß = −3.8, P = 0.01) and less educated (ß = −6.48, P = 0.02) but higher in high-income (ß = 5.7, P = 0.02) people. Only 20% of people were highly prepared. Intention to prepare was higher in families having the elderly (ß = 5.72.8, P = 0.048). Conclusion: Low trust in the managing authorities and their provided information tend to less considering health and preparedness measures in society. [ABSTRACT FROM AUTHOR]

Background: Women are at higher risk of death during disasters due to physical, biological, psychological, and cultural differences. After a disaster, they experience more miscarriages, premature births, inadequate fetal growth, low birth weight, sexual violence, and unwanted pregnancies. This study aims to investigate the reproductive health status of women affected by the 2017 earthquake in Kermanshah, Iran. Materials and Methods: This descriptive cross-sectional study was conducted in 2018. The study population consists of women aged 15-49 years (Mean age=31.7 years) living in Sarpol-e Zahab, Javanrood, and Thalas Babajani towns in Kermanshah city affected by the earthquake in 2017. The questionnaire used for assessing the status of reproductive health in women was the Reproductive Health Assessment Questionnaire for Women of Reproductive Age, which has already been localized in Iran and its reliability and validity have been confirmed. Native Kurdish language experts completed the questionnaires on behalf of 396 participants. Descriptive statistics were used to describe the variables. Results: It was found that 42.4% of women complained of abnormal menstruation and 34.09% of limited menstrual hygiene materials. Sixty women were pregnant at the time of the earthquake, all of whom gave birth in hospital; two had miscarriages, two had premature births, and one had stillbirth. Urinary tract infection was the most common problem (21%) in pregnant women. Moreover, 48% of women used contraceptive methods after the earthquake, the most commonly used method was the use of contraceptive pills (23%). Access to contraception methods was difficult for 14.4% of them after the earthquake. Furthermore, 25% had experienced violence after the earthquake; of these, 30 reported physical violence, 86 verbal violence, and 13 sexual violence. Conclusion: The control of pregnancy and safe delivery in earthquake-affected areas of Kermanshah is relatively acceptable; however, the provision of reproductive health services seems to be challenging. It is recommended to pay attention to the menstrual hygiene of women and regular distribution of contraceptives (despite the current population growth plan), address sexual acts of violence, and develop a protocol to support the victims.

Renewable energy is a core issue when it comes to energy resources today. However, the use of tidal energy has received less attention compared to solar and wind energy. This study investigates the technical‐economic evaluation of tidal power plants in three areas of Bushehr, Pol, and Khowr‐e Musa, all located along the southern coast of Iran. Four economic indices including net present value (NPV), benefit–cost ratio, capital return time, and internal rate of return are used. The study compares a tidal power plant with a solar and a Combined Cycle Gas Turbine power plant bearing a capacity of 10 MW. The results show that the total initial cost of a tidal power plant is 1.92 times higher compared to a PV and 7.16 times higher compared to a CCGT power plant. Due to the potential of solar and tidal energy, the three studied regions are economically different. The results show the NPV of a tidal power plant in Khowr‐e Mousa region is 4.90 times higher than a PV power plant and 9.93 times higher than a CCGT power plant. In addition, the cost of energy production per kilowatt depends on the region and the type of power plant technology. The lowest cost of energy production is related to tidal energy in Khowr‐e Musa region. The results of sensitivity analysis also show that the highest sensitivity is related to the initial cost and electricity sales rate. [ABSTRACT FROM AUTHOR]

Background: Insomnia is a prevalent sleep disorder that has not been well managed thus far. There are numerous medicaments for treatment of insomnia, but they have undesirable side effects that make herbal medicine a more viable option. Objectives: The effectiveness of a combination of Melissa officinalis L. (dry powder) and Nepeta menthoides Boiss. & Buhse (freeze-dried aqueous extract) on insomnia was evaluated. Design and Setting: Insomniacs who met the entry criteria participated in a triple-blind randomized placebo-controlled clinical trial at the Persian Medicine (PM) clinic in Tehran. Interventions: The subjects received either 1000 mg of M. officinalis plus 400 mg N. menthoides or a placebo nightly for four weeks in accordance with prescriptions from the pharmaceutical manuscripts on PM and the results of previous studies. Outcome measures: The Pittsburgh Sleep Quality Index (PSQI), sleep diary, and Insomnia Severity Index (ISI) were used for assessment of insomnia. Results: Comparison of the treatment and placebo groups showed a significant decrease in the mean difference of ISI (4.97 ± 4.69 vs. 1.60 ± 3.70; p =; 0.002) and total PSQI (4.14 ± 3.69 vs. 1.42 ± 2.81; p = 0.001) scores in the treatment group. A significant increase was also observed in total sleep time of treatment group (p < 0.001) based on the sleep diary. Conclusions: A combination of M. officinalis and N. menthoides Boiss. & Buhse could be an alternative sleep improvement therapy. [ABSTRACT FROM AUTHOR]

Background: Needle and Syringe Programs (NSP) have been implemented in Iran since 2002. The primary aim of NSP is to prevent blood-borne virus transmission by providing sterile injecting equipment and information on safer injection practices. However, while NSP has been implemented in Iran for more than a decade, only a limited number of studies have evaluated the effect access to NSP has in reducing risk behaviors among people who inject drugs (PWIDs).Methods: Between September and December 2014 we used snow ball sampling to recruit PWID from Kermanshah for a cross-sectional survey. Participants completed a face-to-face interview and provided information on the frequency of injection and drug-related risk behaviors such as sharing (borrowing or lending) of previously used syringes/needles and the number of injecting partners with whom they have shared syringes/needles in the two months prior to interview. Correlation between drug-related risk behaviors and ability to access NSPs was assessed by bivariate and multiple logistic regression through the estimation of odds ratios (OR) and 95% confidence intervals (95% CI).Results: Of 500 PWIDs in this study, 18%, 36% and 46% reported low, medium and high ability to access NSPs in the two months prior to interview, respectively. The odds of receptive syringe sharing among people with low-access was 3.5 times the odds of people with high-access when adjusted for covariates and remained statistically significant (adjusted odds ratio (AOR): 3.5, 95%CI 1.4–7.7). The relationship between access to NSP and use of sterile-injecting equipment was not statistically significant. The AOR for outcomes like paraphernalia sharing (AOR: 2.5, 95%CI: 0.6–4.6,p-value: 0.6) was not statistically significant.Conclusions: Similar to the previous research in international settings, this study found that PWID who reported to have more access to needle and syringe programs were less likely to use a syringe after someone else had used it. NSP program staff should focus on encouraging more frequent visits, increasing the opening hours and number of locations providing access to sterile syringe in settings with high concentrations of PWID.

Acceptance and willingness to receive the vaccine are among the main factors in the success or failure of a health system in implementing the vaccination program. The present study was conducted in Tehran, the political and economic capital of Iran, to determine the acceptance of the COVID-19 vaccine and identify its associated factors, and explain the most important barriers and acceptance strategies for vaccination. This research was a concurrent quantitative and qualitative mixed-method study. In the quantitative part, 1200 individuals aged more than 18 years were selected from the households in 22 districts of Tehran City, with a multistage stratified cluster sampling method. Two questionnaires were used to evaluate the acceptance of the COVID-19 vaccine and vaccine acceptance determinants. The qualitative content analysis method addressed the influencing factors, as well as challenges and strategies related to the acceptance of the COVID-19 vaccine in four groups of Tehran inhabitants: the elderly, people with underlying diseases, healthcare workers, and the general population. The related data were simultaneously collected by applying in-depth semi-structural interviews and a data analysis process. Furthermore, we used the Graneheim and Lundman method for data analysis. We analyzed the data of 1200 people with a mean (SD) age of 46.4 (11.1) years, and approximately 58% of them were men. The vaccine acceptance was 83.6% (95% CI: 81.3–85.9). Among those who welcomed vaccination, 58% preferred the imported vaccines, 25% the Iranian ones, and 17% both. There was a significant association between the variables of age (adjusted odds ratio [AOR] = 1.72, 95% CI: 1.01–2.93), being single (AOR = 0.54, 95% CI: 0.41–0.91), moderate pharmacotherapy adherence (AOR = 0.58, 95% CI: 0.4–0.85), and the willingness to receive COVID-19 vaccine. Qualitative study after interviewing 45 people from four study groups showed an insufficient social trust in healthcare system officials, pharmaceutical and vaccine production companies; distrust in the effectiveness of the vaccines, concerns about the vaccine adverse effects, being tracked by microchips after vaccination, traditional anti-vaccination movements, the feeling the inessentiality of vaccination, and uncertainty about the fair distribution of the vaccine. These concerns were the main challenges addressed by the study groups. A good proportion of Tehran residents reported their willingness to receive the COVID-19 vaccine. Additionally, they expressed their critical concerns, such as insufficient trust in the healthcare system, vaccine safeties, and adverse effects that were the significant barriers to vaccine acceptance. It seems that conflicts raised by the shortage of vaccines and their import due to the sanctions have led to intense desire and demand in the general population, and especially the elderly, for vaccination. Besides, vaccination phobia in some individuals requires further investigations. [ABSTRACT FROM AUTHOR]

Introduction: Along with the challenges of COVID-19 vaccine supply in low-income countries, vaccine hesitancy was another problem for the health system. The aim of this study was to deeply understand the challenges of vaccine acceptance, the vaccination process, and to compare the affecting vaccine acceptance in the high and low points of the epidemic in Iran., Methods: In the qualitative part of this mixed-methods study, content analysis was used to investigate experiences and perceptions about COVID-19 vaccination in four groups. In the quantitative study, in March 2021 (low point), and on August 1, 2021 (high point), two population-based cross-sectional studies were performed in Tehran and its rural, with sample sizes of 1,200 and 1,872 people aged over 18 years, respectively. Multinomial (polytomous) logistic regression was used to determine the factors affecting hesitation and unwillingness to receive the vaccine., Results: Disbelief in vaccine safety, vaccine distrust, ignorance and confusion, and inadequate facilities were the common reasons extracted in the two qualitative studies. At the low and high points of the epidemic, vaccine acceptance was 83.6% (95% CI: 81.3-85.9) and 65.8% (95% CI: 65.8-71.0), respectively. Residence in rural areas, (Odds Ratio: 0.44, p = 0.001), being a student (Odds Ratio: 0.41, p = 0.011), housewives (Odds Ratio: 0.63, p = 0.033), illiteracy (Odds Ratio: 4.44, p = 0.001), and having an underlying disease (Odds Ratio: 4.44, p = 0.001) were factors affecting on vaccine acceptance., Discussion: Counter-intuitively, acceptance did not increase at the peak of epidemic. The presence of obstacles, such as increased distrust in the effectiveness of vaccines due to the occurrence of multiple peaks in different vaccinated countries, as well as the influence of the media, anti-vaccine campaigns, and lack of proper communication about risks caused more hesitation. More investigation to understand how people accept or reject vaccine and its long term consequences is recommended., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Khankeh, Pourebrahimi, Hosseinabadi-Farahani, Farrokhi, Khanjani, Shojafard, Hamedanchi, Ranjbar, Jenabi Ghods, Ahmadi, Ghanaatpisheh and Saatchi.)

Background: This study aimed to evaluate the association between cognitive and affective empathy and aggression in a sample of Iranian athletes., Methods: We designed a cross-sectional study. The participants were selected by multistage random sampling among six colleges in Tehran, Iran's capital. We used the interpersonal reactivity index (IRI) to evaluate empathy, and Reactive Proactive Aggression Questionnaire, and the Buss-Perry aggression questionnaire to evaluate aggression., Results: In total, 492 athletes with a mean age of 27.42 years (SD = 7.72) participated in the study, of which 298 (60.6%) were male, and 194 (39.4%) were female. IRI's fantasy and personal distress subscales scores were positively associated with proactive and reactive aggression scores (p < 0.05). The score of the perspective-taking subscale of IRI was negatively associated with proactive and reactive aggression scores (p < 0.05). The score of the empathic concern subscale of IRI had a negative association with the proactive aggression score (p < 0.001). The score of the perspective-taking subscale of IRI had negative associations with all Buss-Perry aggression questionnaire subscales' scores (p < 0.05). The score of the personal distress subscale of IRI had positive associations with all Buss-Perry aggression questionnaire subscales' scores (p < 0.05), except with the verbal aggression subscale score. The score of the fantasy subscale of IRI was positively associated with the score of the hostility subscale of the Buss-Perry questionnaire (p = 0.001)., Conclusion: Perspective-taking is negatively associated with all kinds of aggression in athletes. Future studies can be conducted to determine the possible role of perspective-taking in preventive aggression, which can be a target for interventions. On the other hand, the score of the personal distress subscale of IRI is positively associated with all types of aggression scores, indicating that not all types of empathy inhibit aggression in athletes., (© 2022.

Objective: To evaluate the signs/symptoms of different stimulant toxicities in children to determine differences among them., Design: Observational, retrospective, single-center case-series., Setting: The only referral hospital for pediatric poisoned patients in Tehran, Iran, covering 12.5 million permanent and 6.5 million temporary residents., Patients: All children between 2007 and 2012 were evaluated. Their clinical findings, laboratory tests, electrocardiogram, and outcome were evaluated., Interventions: None., Measurements and Main Results: A total of 147 patients were enrolled (115, 24, three, and five with methamphetamine, methylphenidate, ecstasy, and unknown stimulant toxicities, respectively). Median (interquartile range) age of the methamphetamine- intoxicated children (16 mo [22-42 mo]) was significantly less than those with methylphenidate toxicity (66 mo [33-105 mo]). Almost 79% of the patients had ingested the stimulant, whereas 9% had passively been exposed to the methamphetamine smoke. The frequency of stimulant toxicity had significantly increased during the 5-year period of the study. Restlessness, mydriasis, stereotypic movements, and talkativeness were the most common signs and symptoms. Whereas bruxism only seen in 66.7% (95% CI, 21-94%) of ecstasy users, the prevalence of restlessness, sweating, and tremor was also more in this group of children. On the other hand, mydriasis and stereotypic movements were more common in crystal-meth patients by 76.5% (95% CI, 68-83%) and 53% (95% CI, 44-62%), respectively. A comparison between different routes of crystal-meth intoxication showed that flushing was more common in those who had passively/actively smoked/inhaled methamphetamine (odds ratio, 6.3 [95% CI, 1.5-26]). Palpitation was more seen in methylphenidate toxicity by 12.5% (95% CI, 4-31%). Restlessness was more detected in toddlers, whereas talkativeness and ataxia were more common in older children. Nineteen children (21%) had prolonged QTc according to normal values in different ages. None of them died., Conclusions: More studies are warranted to evaluate the frequency and outcome of this poisoning in children. Educational preventive programs are also recommended.
