Following the proposal of Universal Design in 1974, a public society was founded in Iran in 1981, in order to aid the disabled victims of the Iran-Iraq war. Official authorities have also made legislation on this topic. During the last three decades many efforts have been made to apply this concept in public spaces. Unfortunately these have not succeeded. It means despite the existence of inherent rules and regulations and the general will to apply the principles of Universal Design in Tehran, urban spaces are still an improper environment for the independent presence and movement of people with disabilities. This problem is considered a serious threat for social sustainability in Tehran. The main goal of this research is finding solutions for increasing social interaction and greater participation of people with disabilities in public spaces by applying Universal Design. The research is seeking to answer these questions: What is causing inefficiency in the regulation of Universal Design in Tehran? Why is social participation by people with disabilities limited in Tehran? Which factors are contributing to Universal Design in Tehran? The research is based on applied theory, field research methods and a mixed qualitative-quantitative approach. In addition, and the results include both empirical and functional solutions. The consequences show that many of problems are rooted in cultural issues. The people must attend to disability as a public concern which can involve everybody. They must comprehend that all the members of the society, regardless of their physical condition, have the right to use public facilities independently. The second problem is related to lack of any integrated approach to applying Universal Design. This research proposes some solutions such as preparation a Universal Design master plan, an integrated approach for implementation project in all organizations, and public education for improving citizens' knowledge about Universal Design.

Objectives. In this study, we have evaluated the lifetime and past-year prevalence of exposure to physical violence among married women in the city of Tehran and urban and rural areas of Hashtgerd. Methods. The target population were noninstitutionalized female citizens, aged 15 years or older, who have at least one history of marriage and who resided in the capital city of Tehran or Hashtgerd County from the summer of 2008 to fall of 2010. We used a multistage sampling method. Tehran's District Six, a central district in Tehran, was selected as a representative cluster of all municipal districts in Tehran. A total of fifty blocks were randomly selected from this district, from which 1,000 married women aged 15 years or older were interviewed using a cross-sectional design. Data was gathered face-to-face using a structured questionnaire. The lifetime prevalence, past-year prevalence, and related factors of domestic violence were measured. SPSS version 11.5 was used for the analyses. Results. Figures for lifetime prevalence and past-year prevalence were measured to be 38.7% and 6.6%, respectively. The independent effects of marital status and location and type of residency for women, along with education and smoking habits of their spouses, were statistically significant in multivariate logistic regression analysis. Conclusion. Domestic violence is a public health concern in Iran. Based on our findings, we propose that empowering women through education, and improving their ability to find employment and income, along with increasing public awareness of human rights issues through education could lower the prevalence of domestic violence.

There is no reliable estimate of the size of female sex workers (FSWs). This study aimed to estimate the size of FSWs in south of Tehran, Iran in 2016 using direct capture-recapture method. In the capture phase, the hangouts of FSWs were mapped as their meeting places. FSWs who agreed to participate in the study tagged with a T-shirt. The recapture phase was implemented at the same places tagging FSWs with a blue bracelet. The total estimated size of FSWs was 690 (95% CI 633, 747). About 89.43% of FSWs experienced sexual intercourse prior to age 20. The prevalence of human immunodeficiency virus infection among FSWs was 4.60%. The estimated population size of FSWs was much more than our expectation. This issue must be the focus of special attention for planning prevention strategies. However, alternative estimates require to estimating the number FSWs, reliably.

To study the trend of hepatocellular carcinoma incidence after correcting the misclassification in registering cancer incidence across Iranian provinces in cancer registry data. Incidence data of hepatocellular carcinoma were extracted from Iranian annual of national cancer registration reports 2004 to 2008. A Bayesian method was implemented to estimate the rate of misclassification in registering cancer incidence in neighboring province. A beta prior is considered for misclassification parameter. Each time two neighboring provinces were selected to be entered in the Bayesian model based on their expected coverage of cancer cases which is reported by medical university of the province. It is assumed that some cancer cases from a province that has an expected coverage of cancer cases lower than 100% are registered in their neighboring facilitate province with more than 100% expected coverage. There is an increase in the rate of hepatocellular carcinoma in Iran. Among total of 30 provinces of Iran, 21 provinces were selected to be entered to the Bayesian model for correcting the existed misclassification. Provinces with more medical facilities of Iran are Tehran (capital of the country), Razavi Khorasan in north-east of Iran, East Azerbaijan in north-west of the country, Isfahan in central part and near to Tehran, Khozestan and Fars in south and Mazandaran in north of the Iran, had an expected coverage more than their expectation. Those provinces had significantly higher rates of hepatocellular carcinoma than their neighboring provinces. In years 2004 to 2008, it was estimated to be on average 34% misclassification between North Khorasan province and Razavi Khorasan, 43% between South Khorasan province and Razavi Khorasan, 47% between Sistan and balochestan province and Razavi Khorasan, 23% between West Azerbaijan province and East Azerbaijan province, 25% between Ardebil province and East Azerbaijan province, 41% between Hormozgan province and Fars province, 22% betweenChaharmahal and bakhtyari province and Isfahan province, 22% between Kogiloye and boyerahmad province and Isfahan, 22% between Golestan province and Mazandaran province, 43% between Bushehr province and Khozestan province, 41% between Ilam province and Khuzestan province, 42% between Qazvin province and Tehran province, 44% between Markazi province and Tehran, and 30% between Qom province and Tehran. Accounting and correcting the regional misclassification is necessary for identifying high risk areas and planning for reducing the cancer incidence.

Seven rivers originated from the highlands of N Tehran run inside and around the city. Many of these river valleys have been deformed by a variety of urban utilizations such as garden, building, canal, park, autobahn etc. Tehran with more than eight million populations suffered from adverse environmental conditions such as pollution and scarcity of natural habitats for recreational activities. Ecological restoration of altered river valleys of Tehran is one of the priorities of Tehran municipality started as a pilot project in Farahzad river. Intensive disturbance, conversion into various urban utilization, illegal building construction, waste water release into the river, garbage accumulation, artificial park constructions and domination of invasive species have largely altered the river. Parts of the river located in Pardisan Nature Park was studied before its complete deformation into a modern park. The riparian vegetation consisted of Tamarix ramosissima and Salix acmophylla shrubs with large number of aquatic and palustric plants. The norther parts of the river still contain semi-natural vegetation which change into patchy and intensive degraded habitats towards its southern parts. In northern parts of valley there are old gardens of Morus alba and Juglans regia, and planted trees such as Plataneus oreientalis and Acer negundo. Salix acmophylla, Fraxinus excelsior and Celtis caucasica are native species growing on river margin or surrounding steep slopes. The rare local endemic Convolvulus gracillimus still occurs in surrounding dry slopes. Ailanthus altissima is an invasive introduced tree largely occupied disturbed habitats and slopes of the valley associated with large number of ruderals belonging to genera Amaranthus, Bassia, Chenopodium, Echinochloa, Heliotropium, Tribulus etc. Restoration plan include 1. Study of past biological and geomorphological conditions of the area based on remnants of vegetation and aerial and satellite imaginary data 2. Survey of present environmental conditions of the area including identification native and introduced plants and animals, assessing the degree of originality of existing vegetation and cultural landscapes and abiotic factors. 3. Soil reclamation and topography improvements towards cultivation and/or formation of natural vegetation.

Decisions on selecting an appropriate site for temporary shelter used to be taken in a limited amount of time after a disaster. The need for a systematic method in this area inspired the MADM (multi-attribute decision making) for complex disaster management decisions. This research proposes a model for appropriate and systematic site selection for temporary shelters, before an earthquake, using a geographical information system and MADM based on an earthquake damage assessment. After the effective criteria for site selection of temporary shelters are determined, the geographical layers of these criteria are prepared for Municipal District No.1 of Greater Tehran, the capital of Iran. Given these attributes and the required shelter area (415-610 hectares), 14 zones are proposed initially. Various MADM methods are used for the final selection. The mean of the aggregated ranking results are determined, and 10 of the 14 initial zones are ranked. © 2013 The Author(s). Journal compilation © Overseas Development Institute, 2013.

Background: As a waterborne pathogen, Cryptosporidium is one of the most common causes of gastroenteritis in human and hoofed livestock animals. This study aimed to investigate the distribution of Cryptosporidium spp. in human and livestock wastewaters in Iran, by the 18S rRNA sequence analysis. Methods: A total of 54 raw wastewater samples collected from three urban treatment plants and two slaughterhouses during 2014–2015 in Tehran, Iran. The presence of the Cryptosporidium oocysts was assessed by immunofluorescence with monoclonal antibodies. To characterize the oocysts at the molecular level, the 18S rRNA gene of Cryptosporidium was PCR amplified and sequenced. Results: Of the 54 wastewater samples examined, 34 (62.9%) were positive for Cryptosporidium oocysts using the IFA. Of these, 70.5% (24/34) were positive by PCR, that 91.6% (22/24) were successfully sequenced. The species of C. andersoni (95.4%) and C. xiaoi (4.6%) were detected in livestock wastewater samples. Conclusion: C. andersoni was the major Cryptosporidium sp. found in the aquatic environmental wastewater samples. The high rate of detection of C. andersoni in domestic wastewater was probably the result of the predominancy of this species in cattle herds in Iran. The current study is the first report of C. xiaoi in Iran. PMID:28127361

Over the past two decades, drug injection-related risk behaviors have been the major drivers of the HIV epidemic in Iran. This study assesses the access of people who injected drugs (PWID) to harm reduction services (needle-exchange programs [NEP] and methadone maintenance treatment [MMT]) in Tehran, Iran in 2007, almost five years after the large-scale implementation of these programs. 572 consenting PWID (>18 years old, ever injected in the past month, lived in Tehran or its suburbs) were recruited (24 seeds) into a sero-behavioral survey using respondent-driven sampling method. Participants completed a face-to-face interview about HIV-related risk behaviors and access to harm reduction services. We calculated adjusted population estimates using RDSAT. Overall, 99.2% of the participants were male, 41.6% aged between 30 and 39 years old, 55.4% lived alone in the past year, 83.2% were ever incarcerated, and 88.8% lived in the southern areas of Tehran. In terms of "awareness" and "use" of services among PWID, 62.8% and 54.8% reported for NEP (respectively) and 19.7% and 9.1% for drug treatment services (respectively). PWID who lived in Northwest and South-central Tehran were more likely to be aware (85.0% and 82.8%, respectively) of one or more services than PWID who lived elsewhere. Similarly, PWID who lived with friends were more likely to be aware of (88.6%) and use (85.9%) services (vs. other living partners). Overall, 11% of the participants were aware of but had not used any harm reduction services. Despite a relatively high level of access to NEP among PWID in Tehran, a sizable fraction of the population remains without access to other services five years after their implementation. The use of harm reduction may be affected by certain PWID characteristics (e.g., living partners and geographical location). Ongoing surveillance activities are necessary to track change in access over time. Copyright © 2014 Elsevier B.V. All rights reserved.

To determine the pattern of causalities of Iraqi ballistic missile attacks on Tehran, the capital of Iran, during Iraq-Iran war. Data were extracted from the Army Staff Headquarters based on daily reports of Iranian army units during the war. During 52 days, Tehran was stroked by 118 Al-Hussein missiles (a modified version of Scud missile). Eighty-six missiles landed in populated areas. During Iraqi missile attacks, 422 civilians died and 1 579 injured (4.9 deaths and 18.3 injuries per missile). During 52 days, 8.1 of the civilians died and 30.4 injured daily. Of the cases that died, 101 persons (24%) were excluded due to the lack of information. Among the remainders, 179 (55.8%) were male and 142 (44.2%) were female. The mean age of the victims was 25.3 years+/-19.9 years. Our results show that the high accuracy of modified Scud missiles landed in crowded areas is the major cause of high mortality in Tehran. The presence of suitable warning system and shelters could reduce civilian casualties. The awareness and readiness of civilian defense forces, rescue services and all medical facilities for dealing with mass casualties caused by ballistic missile attacks are necessary.

The present inquiry set to determine the economic inequality in history of stillbirth and understanding determinants of unequal distribution of stillbirth in Tehran, Iran. A population-based cross-sectional study was conducted on 5170 pregnancies in Tehran, Iran, since 2015. Principal component analysis (PCA) was applied to measure the asset-based economic status. Concentration index was used to measure socioeconomic inequality in stillbirth and then decomposed into its determinants. The concentration index and its 95% CI for stillbirth was -0.121 (-0.235 to -0.002). Decomposition of the concentration index showed that mother's education (50%), mother's occupation (30%), economic status (26%) and father's age (12%) had the highest positive contributions to measured inequality in stillbirth history in Tehran. Mother's age (17%) had the highest negative contribution to inequality. Stillbirth is unequally distributed among Iranian women and is mostly concentrated among low economic status people. Mother-related factors had the highest positive and negative contributions to inequality, highlighting specific interventions for mothers to redress inequality. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The Molavi street archeological site south of Tehran accidentally provided a unique opportunity for paleoparasitological studies in Iran. A female skeleton was unearthed and evaluated to be 7000 years old. Soil samples were collected around the pelvic and sacrum bones. Careful microscopic investigation of rehydrated soil samples revealed the presence of one Enterobius vermicularis egg attached to the skeleton sacral region. The present finding likely represents the oldest evidence of a human pinworm infection in Asia.

Suicide ranks among the top ten causes of death in all age groups all over the world. There are many methods for committing suicide including self-poisoning, firearm and hanging. The aim of the present study was to provide an overview of self-poisoning related suicidal deaths with special focus on forensic toxicology analysis results in Tehran, Iran from 2011 to 2015. All suspicious cases with the the history of self-poisoning were investigated to define the cause and manner of death under the supervision of forensic medicine practitioners. Postmortem samples were analysed in forensic toxicology laboratory to confirm the presence of drugs in cadaver of suicidal cases. Drugs and poisons were analysed using thin layer chromatography, high performance liquid chromatography, gas chromatography/mass spectrometry, headspace gas chromatography and gas chromatography equipped with nitrogen phosphorus detector. Demographic data were collected from autopsy reports of all cases with confirmed self-poisoning suicidal cause of death. Results showed that 674 cases of self-poisoning deaths were investigated during a five-year study period, of which 68.55% were male. The most often used suicide method was self-poisoning in young population. Phosphine gas liberated from aluminum phosphide tablets was the most toxic substance detected in postmortem samples (619 cases) followed by opioids, methamphetamine, organophosphates, cyanide and strychnine. In conclusion self-poisoning suicidal death was predominant in young male population in Tehran, Iran. It seems that free access to suicide means such as drugs and poisons should be restricted by national and health authorities. Not applicable.

Background: Karate is a public sport that has athletes in various age ranges and abundant active sport clubs in Iran. The pattern of injury in this sport in Iranian athletes seems different from other countries. Objectives: This study was performed with the purpose of considering the incidence and type of injury of karate athletes aged below 30 years from Tehran, Iran clubs. Materials and Methods: In a cross-sectional study, 10 karate clubs were selected in Tehran. Clubs were selected based on a cluster method from 5 different geographical regions of Tehran. All injuries were collected based on athletes’ or clubs’ weekly report with a designed questionnaire. The injuries were classified according to: low, medium and severe injury. Collected data was analyzed with SPSS software version 17. Results: 620 athletes were studied totally and incidence rate of injury per athletes was 16.1% and 20.2 per 100 athletes. Ninety percent of injuries were during bout practice, 6% during fitness and 4% during kata. The rate of injury was more common in athletes with weight less than 70 kg and lower sport experience (P ≤ 0.05). The commonest locations for injury were head and neck followed by trunk, lower and upper limb, respectively. Just 2 cases needed surgical intervention and no one led to decreased level of consciousness. The most common type of injury was contusion, bruise and superficial scratch (64%). Conclusions: Severe injury was uncommon in this study and similar to other Iranian studies head and neck had the most injuries. Athletes with lower experience and lower weight were associated with higher injuries. PMID:26448843

Understanding determinants of socioeconomic inequality in mental health in Iran's capital, Tehran: a concentration index decomposition approach

PubMed Central

2012-01-01

Background Mental health is of special importance regarding socioeconomic inequalities in health. On the one hand, mental health status mediates the relationship between economic inequality and health; on the other hand, mental health as an "end state" is affected by social factors and socioeconomic inequality. In spite of this, in examining socioeconomic inequalities in health, mental health has attracted less attention than physical health. As a first attempt in Iran, the objectives of this paper were to measure socioeconomic inequality in mental health, and then to untangle and quantify the contributions of potential determinants of mental health to the measured socioeconomic inequality. Methods In a cross-sectional observational study, mental health data were taken from an Urban Health Equity Assessment and Response Tool (Urban HEART) survey, conducted on 22 300 Tehran households in 2007 and covering people aged 15 and above. Principal component analysis was used to measure the economic status of households. As a measure of socioeconomic inequality, a concentration index of mental health was applied and decomposed into its determinants. Results The overall concentration index of mental health in Tehran was -0.0673 (95% CI = -0.070 - -0.057). Decomposition of the concentration index revealed that economic status made the largest contribution (44.7%) to socioeconomic inequality in mental health. Educational status (13.4%), age group (13.1%), district of residence (12.5%) and employment status (6.5%) also proved further important contributors to the inequality. Conclusions Socioeconomic inequalities exist in mental health status in Iran's capital, Tehran. Since the root of this avoidable inequality is in sectors outside the health system, a holistic mental health policy approach which includes social and economic determinants should be adopted to redress the inequitable distribution of mental health.

HIV infection rates have reached epidemic proportions amongst injecting drug users (IDUs) in Iran. Although a number of community-based interventions have being implemented in the country, there is little information on the risk behaviors of IDU participants in these programs. This cross-sectional report aimed to compare the risk behaviors of injecting drug users with differential exposure rates to an HIV outreach program in Tehran, Iran. Results indicated that shared use of needle/syringe in the past month was significantly lower among IDUs who received estimated ≥ 7 syringes per week than those who did not [adjusted odds ratio (OR) = 14.36, 95% confidence interval (CI) 2.30–89.56]. While the effectiveness of this outreach program needs further evaluation through a longitudinal investigation, our preliminary findings suggest that the outreach program in Tehran may have been beneficial in reducing direct sharing among those who received more than several needles/syringes from the program.

Health in the adolescence period guarantees the next generation's health. The assessment of health needs is the first stage for the implementation of health promotion interventions. This study aimed to assess the priorities of male adolescent's health needs in Tehran, Iran, in year 2015. This cross-sectional correlational study was conducted with 1,200 male adolescents aged between 13 and 18 years. Single male adolescents studying in public guidance and high schools in Tehran, Iran, in year 2015 were chosen using a random multistage sampling method. Data were collected using the male adolescent health need assessment scale. The data were analyzed using descriptive and inferential statistics. It was found that while the lowest score was for the domain of sexual health, other domains had average or higher than average scores. More attention should be paid to the sexual health needs of male adolescents. Policy makers need to design strategies that help meet the health needs of male adolescents.

Multiplatform observations of dust vertical distribution during transport over northwest Iran in the summertime

Dynamical processes leading to dust emission over Iran and surrounding countries in the summer as well as the subsequent transport of dust toward northwest Iran are analyzed on the basis of two case studies using a suite of ground-based and spaceborne remote sensing platforms together with modeling tools. Ground-based lidar measurements acquired in Zanjan provide new insight into the vertical distribution of dust linked to transport over northwest Iran and highlight the importance of low-level transport of dust from both Iraq and Iran for air quality issues in Tehran. During the 3-5 August 2007 case, dust emission regions are located in Syria/Iraq and close to Qom, Iran, in a large intermittent salt lake in the western part of the Dasht-e Kavir desert. The visibility in Tehran associated with this event decreases significantly (reaching 7 km) on 5 August 2007 only. During the 11-13 September 2008 case, the dust transported to northwest Iran originates from Syria/Iraq only. The visibility in Tehran during this case is low throughout the period, sometimes less than 5 km due to the transport of dust at low levels. In both cases, emissions in Syria and Iraq occur in response to strong Shamal winds. However, transport of dust toward Iran takes place at different levels: above 700 hPa in August and below 700 hPa in September. This is found to be related to the presence of strong northeasterly winds over the Zagros Mountains as well as in its lee (south of the range) in the August case only. In August also, dust emissions in the Qom region results from strong winds blowing over the Dasht-e Kavir desert.

Abstract Background The present study was conducted to determine the association between social support and health-related QOL (HRQL) for a sample of 120 patients living with HIV/AIDS in Tehran. Method Eighty male and 40 female living with HIV referred to Iranian AIDS Research Center at Imam Khomini Hospital in Tehran, Iran in 2011 were randomly selected for assessment. Data was collected by means of Vaux's Social Support questionnaire and Medical Outcomes Short-Form-36 (SF-36) QOL questionnaires. Pearson (P) Correlation Coefficient and Fisher z-test were used for statistical analysis. Results In general, social support was significantly associated with overall QOL in men (P = 0.001) and women (P = 0.009) living with HIV/AIDS. In men, social support was significantly associated with mental and physical domains of QOL (P = 0.001) while in women it simply associated with mental domain of QOL (P = 0.003). Conclusions Our findings indicate that increasing social support for HIV/AIDS persons increases their QOL. This can help those physicians who are involved in care of HIV-infected persons and it maintains QOL across the spec-trum of HIV disease. PMID:26060686

Production of iodized salt in Iran for household consumption began in 1990. Previous studies have reported sustainable elimination of iodine deficiency disorders in Iran. The aim of this study was to evaluate the iodine nutritional status in Tehran in 2009. In this cross-sectional study, 383 Tehranian households were enrolled through randomized cluster sampling and a total of 639 adult subjects (242 men and 397 women), aged 19 and over, participated. A 24-hour urine sample was collected for measurement of urinary iodine, sodium, and creatinine concentrations using the digestion method, flame photometry, and autoanalyzer assay, respectively. Salt intake was estimated and iodine content of household salt was measured by titration. Median (interquartile range) iodine content of household salt and urinary iodine concentration (UIC) in Tehran were 21.2 (3.2-31.7) parts per million and 70.0 (34.0-131.2) μg/L, respectively. There was no statistically significant difference in 24-hour UICs between men and women. Median (interquartile range) daily salt intake was 7.6 (5.5-9.8) g, which was not different in the two genders. According to the WHO/ICCIDD/UNICEF classification, 11.2%, 25.9%, 26.7%, 25.1%, 8.0%, and 3.2% of participants had UIC <20, 20-49, 50-99, 100-199, 200-299, and >300 μg/L, respectively. Mild iodine deficiency has recurred in Tehranians. The results emphasize the need for continuous monitoring in all regions, even in a country with iodine sufficiency.

Will Iran develop nuclear weapons capabilities and what effects would such capabilities have on international peace and security? Despite two recent U.N. Security Council resolutions sanctioning Iran for its nuclear activities, the government in Tehran continues to press ahead with efforts to expand its uranium enrichment program to industrial scale. But both the Tehran regime and the Iranian people remain divided on the nuclear question, creating opportunities for a negotiated settlement. It is essential for US security that the Iranian program be contained, for nuclear weapons in Iran would increase risks of regional instability, terrorist use, and further proliferation.

PubMed Central

2012-01-01

Background and purpose of the study Pharmacies as direct providers of medicine and pharmaceutical services to patients have an important role in the health status of a society. The assessment of their financial situations by healthcare policy makers is necessary to prevent any negative effects on population's health. In this study we aim to analyze the financial status of pharmacies in Tehran, Iran. Methods This study is a cross-sectional study based on a survey. Two-hundred and eighty-eight private community daytime pharmacies in Tehran were selected by random sampling. We used two questionnaires to collect data regarding cost, expense and income factors of private pharmacies and the significance of each of them from these selected pharmacies. The data was collected in 2011 from Tehran pharmacies. Profitability of pharmacies in Tehran, Iran was calculated in its current situation and then estimated for three defined scenarios: 1. The dispensing fee is omitted (ceteris paribus), 2. Pharmacies are prohibited from selling hygienic & cosmetic products (ceteris paribus), 3. Scenarios 1 and 2 together (ceteris paribus). These data were analyzed by using SPSS and descriptive-analytic statistics. Results About 68% of interviewees responded to our questionnaires. Our analysis indicated that the average annual costs (and expenses), income and profits of pharmacies are 73,181; 106,301; and 33,120 United States Dollar (USD), respectively. The analysis indicated that omission of dispensing fee (scenario 1) and prohibition of pharmacies from selling hygienic & cosmetic products (scenario 2) would decrease income of pharmacies to 18438 and 14034 USD/year, respectively. According to respondents, the cost (or expense) of properties and buildings, energy, taxes, delays in reimbursement by insurance companies, and renting the place of pharmacy could be considered as cost factors and prescription medicines, OTC medicines, dispensing fees, hygienic & cosmetic products, and long-term payment to pharmaceutical distribution companies as income factors, which have significant effects on a pharmacy's economy. Major conclusions According to the results of this study, regarding the pharmacies' cost (and expenses) and incomes, the omission of dispensing fees for prescriptions has considerable negative effects on the profitability of pharmacies and likely on society's health.

Some epidemiological evidence has shown a relation between ambient air pollution and adverse health outcomes. The aim of this study was to investigate the effect of air pollution on mortality from respiratory diseases in Tehran, Iran. In this ecological study, air pollution data was inquired from the Tehran Province Environmental Protection Agency and the Tehran Air Quality Control Company. Meteorological data was collected from the Tehran Meteorology Organization and mortality data from the Tehran Cemetery Mortality Registration. Generalized Additive Models (GAM) was used for data analysis with different lags, up to 15 days. A 10-unit increase in all pollutants except CO (1-unit) was used to compute the Relative Risk of deaths. During 2005 until 2014, 37,967 respiratory deaths occurred in Tehran in which 21,913 (57.7%) were male. The strongest relationship between NO 2 and PM 10 and respiratory death was seen on the same day (lag 0), and was respectively (RR = 1.04, 95% CI: 1.02-1.07) and (RR = 1.03, 95% CI: 1.02-1.04). O 3 and PM 2.5 had the strongest relationship with respiratory deaths on lag 2 and 1 respectively, and the RR was equal to 1.03, 95% CI: 1.01-1.05 and 1.06, 95% CI: 1.02-1.10 respectively. NO 2 , O 3 , PM 10 and PM 2.5 also showed significant relations with respiratory deaths in the older age groups. The findings of this study showed that O 3 , NO 2 , PM 10 and PM 2.5 air pollutants were related to respiratory deaths in Tehran. Reducing ambient air pollution can save lives in Tehran.

We aimed to develop and evaluate outcomes of a blended learning (BL) program for educating nursing and midwifery students of Tehran university of medical sciences (Tehran, Iran). This was a participatory action research project. After designing BL website, providing technological infrastructures, and holding preparatory workshops, 22 blended courses were designed. BL method was implemented for one semester. Students' grade point average, participation with courses, and opinion about educational methods, and instructors' attitude and opinion about educational methods were assessed. Most students (n = 181; 72.1%) and 17 instructors (28.3%) consented to participate in the study. Students' grade point average and participation was significantly higher in BL rather than in face-to-face method (P < 0.0001). Most instructors (n = 11, 65%) had positive attitude toward BL method. Textual analysis of participants' opinion showed that most students preferred BL method and felt more independent in this method. However, they complained about lack of easy access to Internet and weakness in computer skills. Instructors admired the flexibility and incentives that had been provided in the program. However, some of them complained about the time-consuming nature of BL course design. The program showed positive effect on students' learning outcomes and participation. The strengths and weaknesses of the program should be considered for development of next phase of the project. Lessons learned in this phase might be helpful for decision makers who tend to develop similar programs in Iran. Motivational and communicational issues and users' IT skills should be addressed in every BL program.

Food safety has a direct impact on human health and as such is a growing concern worldwide. Presence of harmful pesticide residue in food is a serious cause for concern among consumers so it is important to monitor levels of pesticides in foods. The aim of this study was simultaneous determination of concentrations of 58 pesticides in 40 wheat flour samples collected from Tehran market in January, 2014. The city under study (Tehran) was divided into five districts and samples were collected independently from each district and sourced from different bakeries (n=40). A gas chromatography-mass spectrometry single quadrupole selected ion monitoring «GC/MS-SQ-SIM» method was used to quantify residue of 58 pesticides in the wheat flour samples. Four of the 40 samples showed contamination with Malathion (2 samples: 50.96 ± 11.38 and 62.088 ± 11.38 ppb) and 2, 4-DDE (2 samples: 19.88±15.24 and 13.7 ± 15.24 ppb). that had levels below MRLs of these pesticides in Iran. Averages of recovery of pesticides at 6 concentration levels were in the range of 81.61-118.41%. The method was proven as repeatable with RSDr in the range of 6.5-29.45% for all concentration levels. The limit of quantification for 37 of the tested pesticides was calculated as 15 ppb and for the other 21 tested pesticides, the concentration was 25 ppb. In summary, results of these tests suggested that the wheat flour consumed in Tehran, was within safety limits in terms of levels of pesticide residues. PMID:29201093

Fascioliasis is a zoonotic disease of livestock and human caused by Fasciola species. Here in, the results of serological evaluation of fascioliasis in people referring to the School of Public Health, Tehran University of Medical Sciences during 2008-2014 are presented. Demographic characterizations, symptoms and eosinophil rate were registered for every patient. Using somatic antigen of Fasciola, ELISA was performed and the results were analyzed. Data of questioners were analyzed as well. Among 206 applicants, 24.8% were seropositive for fascioliasis, included 21% female and 28.3% male. Mean range of age of patients was between 13 to 67 yr. The highest rate of seropositivity was found among 20-30 yr old patients. Most of the patients had hypereosinophilia. All patients had history of eating raw vegetables, or drinking unsafe water. Patients were referring from different provinces of Iran, including Gilan, Mazandaran, Tehran, Ardabil, Khuzestan, Lorestan, North Khorasan, Kermanshah, Azerbaijan, Fars, Kordestan, Hamedan and Markazi. During recent years, variety of provinces in Iran, where patients with fascioliasis are referred, has been increased. Patients coming from Gilan and Mazandaran provinces were referred early after the onset of their symptoms. Most probably, physicians in Gilan and Mazandaran are more alert on fascioliasis than other provinces. Previous wrong diagnosis was more common among patients referring from other provinces than Gilan and Mazandaran provinces.

Karate is a public sport that has athletes in various age ranges and abundant active sport clubs in Iran. The pattern of injury in this sport in Iranian athletes seems different from other countries. This study was performed with the purpose of considering the incidence and type of injury of karate athletes aged below 30 years from Tehran, Iran clubs. In a cross-sectional study, 10 karate clubs were selected in Tehran. Clubs were selected based on a cluster method from 5 different geographical regions of Tehran. All injuries were collected based on athletes' or clubs' weekly report with a designed questionnaire. The injuries were classified according to: low, medium and severe injury. Collected data was analyzed with SPSS software version 17. 620 athletes were studied totally and incidence rate of injury per athletes was 16.1% and 20.2 per 100 athletes. Ninety percent of injuries were during bout practice, 6% during fitness and 4% during kata. The rate of injury was more common in athletes with weight less than 70 kg and lower sport experience (P ≤ 0.05). The commonest locations for injury were head and neck followed by trunk, lower and upper limb, respectively. Just 2 cases needed surgical intervention and no one led to decreased level of consciousness. The most common type of injury was contusion, bruise and superficial scratch (64%). Severe injury was uncommon in this study and similar to other Iranian studies head and neck had the most injuries. Athletes with lower experience and lower weight were associated with higher injuries.

Preterm birth (PTB) is a leading cause of neonatal death and the second biggest cause of death in children under five years of age. The objective of this study was to determine the prevalence of PTB and its associated factors using logistic regression and decision tree classification methods. This cross-sectional study was conducted on 4,415 pregnant women in Tehran, Iran, from July 6-21, 2015. Data were collected by a researcher-developed questionnaire through interviews with mothers and review of their medical records. To evaluate the accuracy of the logistic regression and decision tree methods, several indices such as sensitivity, specificity, and the area under the curve were used. The PTB rate was 5.5% in this study. The logistic regression outperformed the decision tree for the classification of PTB based on risk factors. Logistic regression showed that multiple pregnancies, mothers with preeclampsia, and those who conceived with assisted reproductive technology had an increased risk for PTB ( p < 0.05). Identifying and training mothers at risk as well as improving prenatal care may reduce the PTB rate. We also recommend that statisticians utilize the logistic regression model for the classification of risk groups for PTB.

Objective There have been contradictory findings on the relationship between Socioeconomic Status (SES) and child development although SES is associated with child development outcomes. The present study intended to define the relationship between SES and child development in Tehran kindergartens, Iran. Materials & Methods This cross-sectional survey studied 1036 children aged 36-60 month, in different kindergartens in Tehran City, Iran, in 2014-2015. The principal factor analysis (PFA) model was employed to construct SES indices. The constructed SES variable was employed as an independent variable in logistic regression model to evaluate its role in developmental delay as a dependent variable. Results The relationship between SES and developmental delay was significant at P=0.003. SES proved to have a significant (P<0.05) impact on developmental delay, both as an independent variable and after controlling risk factors. Conclusion There should be more emphasis on developmental monitoring and appropriate intervention programs for children to give them higher chance of having a more productive life. PMID:28698723

This letter uses a combination of ADInSAR with a coherence optimization method. Polarimetric DInSAR is able to enhance pixel phase quality and thus coherent pixel density. The coherence optimization method is a search-based approach to find the optimized scattering mechanism introduced by Navarro-Sanchez [1]. The case study is southwest of Tehran basin located in the North of Iran. It suffers from a high-rate of land subsidence and is covered by agricultural fields. Usually such an area would significantly decorrelate but applying polarimetric ADInSAR it is possible to obtain a more coherent pixel coverage. A set of dual-pol TerraSAR-X images was ordered for polarimetric ADInSAR procedure. The coherence optimization method is shown to have increased the density and phase quality of coherent pixels significantly.

Background The aim of this study was to assess the levels of Maslow’s hierarchy of needs theory had been fulfilled and to compare the Maslow’s hierarchy of needs among Iranian different ethnic groups at Tehran University of Medical Sciences (TUMS). Methods: This research was a descriptive-analytical study which conducted among administrative employees of Tehran University of Medical Sciences; Tehran, Iran. The structured questionnaire consisted of 20 questions and demographic details. Each question had 4 parts to measure Maslow’s hierarchy of needs. The questionnaire was distributed randomly among 133 employees to fill-up the demographic details and the other questions. Data was collected and analyzed by SPSS software, and One Way ANOVA, T-test, Spearman and Mann Whitney statistical methods. Results: TUMS ethnic groups of the employees placed most importance on Basic, Self-esteem and Self-actualization. In addition, we found that Persians, Mazandaranians, and Turks ethnic groups, scored the most mean for Maslow’s hierarchical needs compared to the other ethnic groups. Conclusion: Basic needs and safety needs is available amongst the different ethnic groups in Iran. As though, self-actualization needs are ultimate human goal, Iranian employees’ ethnic groups pay emphasis on these needs. We believe that new structures and work practices such as prevailing cultural values and beliefs of the society or the organizations must be explored if Iranian-based organizations want to remain responsive to the needs of the workplace.

Objectives: Colorectal cancer (CRC) may now be the second most common cancer in the world. The aim of this study was to determine whether clusters of high and low risk of CRC might exist at the neighborhood level in Tehran city. Methods: In this study, new cases of CRC provided from Cancer Registry Data of the Management Center of Ministry of Health and Medical Education of Iran in the period from March 2008 to March 2011 were analyzed. Raw standardized incidence rates (SIRs) were calculated for CRC in each neighborhood, along with ratios of observed to expected cases. The York and Mollie (BYM) spatial model was used for smoothing of the estimated raw SIRs. To discover clusters of high and low CRC incidence a purely spatial scan statistic was applied. Results: A total of 2,815 new cases of CRC were identified and after removal of duplicate cases, 2,491 were geocoded to neighborhoods. The locations with higher than expected incidence of CRC were northern and central districts of Tehran city. An observed to expected ratio of 2.57 (p<0.001) was found for districts of 2, 6 and 11, whereas, the lowest ratio of 0.23 (p<0.001) was apparent for northeast and south areas of the city, including district 4. Conclusions: This study showed that there is a significant spatial variation in patterns of incidence of CRC at the neighborhood level in Tehran city. Identification of such spatial patterns and assessment of underlying risk factors can provide valuable information for policymakers responsible for equitable distribution of healthcare resources.

Background: Assessment of hospitals’ performance in achieving its goals is a basic necessity. Measuring the efficiency of hospitals in order to boost resource productivity in healthcare organizations is extremely important. The aim of this study was to measure technical efficiency and determining status of resource allocation in some university hospitals, in Tehran, Iran. Methods: This study was conducted in 2012; the research population consisted of all hospitals affiliated to Iran and Tehran medical sciences universities of. Required data, such as human and capital resources information and also production variables (hospital outputs) were collected from data centers of studied hospitals. Data were analyzed using data envelopment analysis (DEA) method, Deap2,1 software; and the stochastic frontier analysis (SFA) method, Frontier 4,1 software. Results: According to DEA method, average of technical, management (pure) and scale efficiency of the studied hospitals during the study period were calculated 0.87, 0.971, and 0.907, respectively. All kinds of efficiency did not follow a fixed trend over the study time and were constantly changing. In the stochastic frontier's production function analysis, the technical efficiency of the studied industry during the study period was estimated to be 0.389. Conclusion: This study represented hospitals with the highest and lowest efficiency. Reference hospitals (more efficient states) were indicated for the inefficient centers. According to the findings, it was found that in the hospitals that do not operate efficiently, there is a capacity to improve the technical efficiency by removing excess inputs without changes in the level of outputs. However, by the optimal allocation of resources in most studied hospitals, very important economy of scale can be achieved. PMID:26793657

Background Non-dermatophyte onychomycosis (NDO) is caused by a wide range of mold fungi other than dermatophytes, and has been reported at various rates in different countries worldwide. Studies on the incidence of NDO in the community are essential for understanding its epidemiology and control, as well as for the appropriate treatment of these infections. Objectives In this study, the incidence of NDO in Tehran, Iran, was compared to the incidence of onychomycoses due to dermatophytes and yeasts. Methods From 2014 through 2015, samples from a total of 1,069 patients with suspected fungal nail diseases, who were referred to three medical mycology laboratories in Tehran, were collected and subjected to direct examination (all samples) and culture (788 samples). Differentiation of the causative agents of onychomycosis was based on microscopic observation of characteristic fungal elements in the nail samples and growth of a significant number of identical colonies on the culture plate. Results Based on only direct microscopy, onychomycosis was diagnosed in 424 (39.6%) cases, among which 35.8% were caused by dermatophytes, 32.7% by yeasts, and 29.3% by non-dermatophyte molds (NDMs), while 2.2% were mixed infections. Direct exam was significantly more sensitive than culture for the diagnosis. The most commonly isolated NDMs were Aspergillus spp. (69.3%, n = 52), followed by Fusarium spp. (n = 7). The other isolated species were Paecilomyces spp., Scopulariopsis spp., Acremonium spp., Cladosporium spp., and Chrysosporium spp., with only one case of each. Conclusions An increasing frequency of NDO compared to onychomycosis due to other causative agents has been noticeable over the past few years in Iran. This epidemiological data may be useful in the development of preventive and educational strategies. PMID:27800138

Background In recent years, much attention has been paid to occupational stress, but relatively little or no research has been conducted on the influence of knowledge, attitude, and practice of radiation protection (RP-KAP) on job stress among radiation workers Objectives This study aims to assess job stress among health care workers in Iran who are occupationally exposed to radiation in order to determine the effects of KAP on self-protection against radiation on their job stress. Materials and Methods The population in this descriptive cross-sectional study comprised 670 healthcare workers, including 428 staff with a degree in radiology and 242 other medical personnel who were working in 16 hospitals affiliated with Tehran University of Medical Sciences (TUMS) in Tehran, Iran. The census method was used to sample the workers. In total, 264 staff with a degree in radiology and 149 other medical personnel completed the job content questionnaire (JCQ) and the RP-KAP questionnaire from May to November 2014. Results The prevalence rate of job stress was 22.5% based on calculation formulas and possible scores on the JCQ. Sex, RP-knowledge, attitude, practice, and in-service training predicted 41.8% of the variance in job stress. According to the results of the binary logistic regression, workers with higher scores on knowledge (OR = 0.82, 95% CI: 0.75 - 0.90), attitude (OR = 0.71, 95% CI: 0.63 - 0.82), and practice (OR = 0.78, 95% CI: 0.72 - 0.86) and those who had participated in training programs had significantly lower rates of job stress (OR = 0.51, 95% CI: 0.28 - 0.93). Conclusions The effects of RP knowledge, attitude, and practice on job stress were significant. In order to reduce job stress in radiation environments, ongoing training programs related to self-care and protection principles are recommended. PMID:28180020

The purpose of this study was to assess living and workplace safety conditions of construction workers in Tehran, Iran. This cross-sectional study was conducted among 410 construction sites in a municipal area of Tehran whose municipal building permits were issued in 2011. Data on ventilation, workplace safety and hygiene were collected by direct observation and interviews with site foremen. Noise levels were estimated from 10 sound-level-meter stations in the municipality area. Lack of ventilation in the workers' rooms was abundant. Bathrooms were unhygienic and minimum requirements such as lighting and ventilation did not exist in 80% of the cases. In nearly 50% of large construction sites, sewage and garbage disposal were inappropriate. Elevator safety was poor at all sites and no measures for fall prevention were present in over 88% of active construction sites. This study showed that the mean 24-h equivalent continuous sound level Leq was over 70 dB in 80% of the sites during weekdays. The results of this study revealed poor health and safety living and working conditions of construction workers in Tehran.

The aim of this study was to assess the levels of Maslow's hierarchy of needs theory had been fulfilled and to compare the Maslow's hierarchy of needs among Iranian different ethnic groups at Tehran University of Medical Sciences (TUMS). This research was a descriptive-analytical study which conducted among administrative employees of Tehran University of Medical Sciences; Tehran, Iran. The structured questionnaire consisted of 20 questions and demographic details. Each question had 4 parts to measure Maslow's hierarchy of needs. The questionnaire was distributed randomly among 133 employees to fill-up the demographic details and the other questions. Data was collected and analyzed by SPSS software, and One Way ANOVA, T-test, Spearman and Mann Whitney statistical methods. TUMS ethnic groups of the employees placed most importance on Basic, Self-esteem and Self-actualization. In addition, we found that Persians, Mazandaranians, and Turks ethnic groups, scored the most mean for Maslow's hierarchical needs compared to the other ethnic groups. Basic needs and safety needs is available amongst the different ethnic groups in Iran. As though, self-actualization needs are ultimate human goal, Iranian employees' ethnic groups pay emphasis on these needs. We believe that new structures and work practices such as prevailing cultural values and beliefs of the society or the organizations must be explored if Iranian-based organizations want to remain responsive to the needs of the workplace.

Background Due to the tropism of human parvovirus B19 to erythroid progenitor cells, infection in patients with an underlying hemolytic disorder such as beta-thalassemia major leads to suppression of erythrocyte formation, referred to as transient aplasia crisis (TAC), which may be life-threatening. We investigated the prevalence of parvovirus B19 among patients with beta thalassemia major attending the Zafar Adult Thalassemia Clinic in Tehran, Iran. Methods This cross-sectional study was performed to determine the presence of parvovirus B19 DNA in blood samples and parvovirus B19 genotypes in plasma samples of patients with thalassemia major. The population consisted of 150 patients with beta-thalassemia major who attended the Zafar clinic in Tehran. Specimens were studied using a real-time polymerase chain reaction assay. Results The prevalence of parvovirus B19 in our study population was 4%. Of 150 patients with thalassemia, six (4%) were positive for B19 DNA. There was no significant correlation between blood transfusion frequency and B19 DNA positivity. Finally, phylogenetic analysis of human parvovirus B19 revealed genotype I in these six patients. Conclusion In this study, acute B19 infections were detected in patients with beta thalassemia major. Screening of such high-risk groups can considerably reduce the incidence and prevalence of B19 infection; thus, screening is required for epidemiologic surveillance and disease-prevention measures.

Background: To determine the hospital required beds using stochastic simulation approach in cardiac surgery departments. Methods: This study was performed from Mar 2011 to Jul 2012 in three phases: First, collection data from 649 patients in cardiac surgery departments of two large teaching hospitals (in Tehran, Iran). Second, statistical analysis and formulate a multivariate linier regression model to determine factors that affect patient's length of stay. Third, develop a stochastic simulation system (from admission to discharge) based on key parameters to estimate required bed capacity. Results: Current cardiac surgery department with 33 beds can only admit patients in 90.7% of days. (4535 d) and will be required to over the 33 beds only in 9.3% of days (efficient cut off point). According to simulation method, studied cardiac surgery department will requires 41–52 beds for admission of all patients in the 12 next years. Finally, one-day reduction of length of stay lead to decrease need for two hospital beds annually. Conclusion: Variation of length of stay and its affecting factors can affect required beds. Statistic and stochastic simulation model are applied and useful methods to estimate and manage hospital beds based on key hospital parameters. PMID:27957466

PubMed Central

2018-01-01

Objectives The aim of this study was to determine the factors associated with the spatial distribution of the incidence of colorectal cancer (CRC) in the neighborhoods of Tehran, Iran using Bayesian spatial models. Methods This ecological study was implemented in Tehran on the neighborhood level. Socioeconomic variables, risk factors, and health costs were extracted from the Equity Assessment Study conducted in Tehran. The data on CRC incidence were extracted from the Iranian population-based cancer registry. The Besag-York-Mollié (BYM) model was used to identify factors associated with the spatial distribution of CRC incidence. The software programs OpenBUGS version 3.2.3, ArcGIS 10.3, and GeoDa were used for the analysis. Results The Moran index was statistically significant for all the variables studied (p<0.05). The BYM model showed that having a women head of household (median standardized incidence ratio [SIR], 1.63; 95% confidence interval [CI], 1.06 to 2.53), living in a rental house (median SIR, 0.82; 95% CI, 0.71 to 0.96), not consuming milk daily (median SIR, 0.71; 95% CI, 0.55 to 0.94) and having greater household health expenditures (median SIR, 1.34; 95% CI, 1.06 to 1.68) were associated with a statistically significant elevation in the SIR of CRC. The median (interquartile range) and mean (standard deviation) values of the SIR of CRC, with the inclusion of all the variables studied in the model, were 0.57 (1.01) and 1.05 (1.31), respectively. Conclusions Inequality was found in the spatial distribution of CRC incidence in Tehran on the neighborhood level. Paying attention to this inequality and the factors associated with it may be useful for resource allocation and developing preventive strategies in atrisk areas. PMID:29397644

Distribution and seasonal variation of sixteen priority polycyclic aromatic hydrocarbons (PAHs) were investigated in the drinking water of Tehran, the capital of Iran. Detected single and total PAHs concentrations were in the range of 2.01-38.96 and 32.45-733.10 ng/L, respectively, which were quite high compared to the values recorded in other areas of the world. The average occurrence of PAHs with high molecular weights was 79.55%; for example, chrysene occurred in 60.6% of the samples, with a maximum concentration of 438.96 ng/L. In addition, mean carcinogen to non-carcinogen PAHs ratio was 63.84. Although the concentration of benzo[a]pyrene, as an indicator of water pollution to PAHs, was lower than the guideline value proposed by World Health Organization (WHO) as well as that of Iranian National Drinking Water Standards for all of the samples, the obtained results indicated that carcinogen PAHs present in the drinking water of Tehran can cause threats to human health.

Methadone has a long history of pain relief and successful substitute for maintenance treatment in heroin and narcotic addiction. The aim of the study was to assess the trends of methadone-associated deaths in Tehran, Iran, in 2009-2015, from a forensic toxicology point of view. All methadone-associated deaths during this 7-year study period were evaluated according to demographic parameters and forensic toxicology analysis results. Results showed that 1274 cases of methadone-associated deaths were investigated during the study period. The incidence rate of methadone-associated deaths had risen 7.7 times in 2015 in comparison with 2009 (p < 0.05). The majority of cases were men (90.35%), aged from 20 to 40 years. About 80% of cases had shown positive results for other drugs and poisons in combination with methadone. Methamphetamine and tramadol were the most drugs detected in post-mortem samples. Death rates among methadone users in Tehran, Iran, increased year by year during 2009-2015. These findings raise the attention to the concomitant use of drugs with the need for changes in regulation and regulatory policy to restrict access and use of controlled drugs. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

Assessment of hospitals' performance in achieving its goals is a basic necessity. Measuring the efficiency of hospitals in order to boost resource productivity in healthcare organizations is extremely important. The aim of this study was to measure technical efficiency and determining status of resource allocation in some university hospitals, in Tehran, Iran. This study was conducted in 2012; the research population consisted of all hospitals affiliated to Iran and Tehran medical sciences universities of. Required data, such as human and capital resources information and also production variables (hospital outputs) were collected from data centers of studied hospitals. Data were analyzed using data envelopment analysis (DEA) method, Deap2,1 software; and the stochastic frontier analysis (SFA) method, Frontier 4,1 software. According to DEA method, average of technical, management (pure) and scale efficiency of the studied hospitals during the study period were calculated 0.87, 0.971, and 0.907, respectively. All kinds of efficiency did not follow a fixed trend over the study time and were constantly changing. In the stochastic frontier's production function analysis, the technical efficiency of the studied industry during the study period was estimated to be 0.389. This study represented hospitals with the highest and lowest efficiency. Reference hospitals (more efficient states) were indicated for the inefficient centers. According to the findings, it was found that in the hospitals that do not operate efficiently, there is a capacity to improve the technical efficiency by removing excess inputs without changes in the level of outputs. However, by the optimal allocation of resources in most studied hospitals, very important economy of scale can be achieved.

Background: In recent years, skin diseases in wrestling have finally received the attention they deserve. Outbreaks of tinea corporis are often associated with sports involving extensive bodily contact; such sports include wrestling. Tinea corporis gladiatorum is primarily caused by Trichophyton tonsurans, infecting wrestlers at alarming rates. The management of skin infections in wrestlers and other athletes in sports involving skin-to-skin contact entails numerous challenges, from making an accurate diagnosis to determining eligibility for playing the sports. To control outbreaks, we conducted an epidemiologic investigation. The purpose of this article is to determine the prevalence of tinea corporis gladiatorum in wrestlers in Tehran, Iran. Materials and Methods: A study of dermatophytosis was carried out during the period of March 2004 to December 2005 on 612 mycological proven cases of dermatophytosis found in male wrestlers in Tehran. Mycological examination consisted of culturing of pathologic material followed by direct microscopic observation. Diagnosis was based on macroscopic and microscopic characteristics of the colonies. Results: T. tonsurans was the predominant dermatophyte, accounting for >90% of all tinea corporis gladiatorum isolates during the 2 year analysis. Tinea corporis gladiatorum was found to be more frequent in individuals between the ages of 10 and 20 years of age (72.7%). Wrestlers with tinea corporis gladiatorum were predominantly from wrestling clubs in southern and southeastern Tehran. Transmission of tinea corporis is primarily through skin-to-skin contact. Conclusion: Rapid identification and treatment of tinea corporis gladiatorum is required to minimize the disruption of team practices and competitions. Infection with dermatophytes can disqualify a wrestler from competing in matches, and thus, vigilant surveillance and rapid initiation of treatment is important to prevent the suspension of team practices and competitions.

Parkinsonism occurs in all ethnic groups worldwide; however, there are wide variations in the prevalence rates reported from different countries, even for neighboring regions. The huge socioeconomic burden of parkinsonism necessitates the need for prevalence studies in each country. So far, there is neither data registry nor prevalence information on parkinsonism in the Iranian population. The aim of our study was to estimate the prevalence rate of probable parkinsonism in a huge urban area in Iran, Tehran using a community-based door-to-door survey. We used a random multistage sampling of the households within the network of health centers consisting of 374 subunits in all 22 districts throughout the entire urban area of Tehran. Overall, 20,621 individuals answered the baseline checklist and screening questionnaire and data from 19,500 persons aged ≥30 years were entered in the final analysis. Health care professionals used a new six-item screening questionnaire for parkinsonism, which has been previously shown to have a high validity and diagnostic value in the same population. A total of 157 cases were screened for parkinsonism using the validated six-item questionnaire. After age and sex adjustment based on the Tehran population, the prevalence of parkinsonism was calculated as 222.9 per 100,000. Using the World Health Organization's World Standard Population, the standardized prevalence rate of parkinsonism was 285 per 100,000 (95% confidence interval 240-329). The male:female ratio of probable parkinsonism was calculated as 1.62, and there was a significant increase in the screening rate by advancing age. The calculated rates for the prevalence of parkinsonism in our study are closer to reports from some European and Middle Eastern countries, higher than reports from Eastern Asian and African populations, and lower than Australia. The prevalence rate of >200 in 100,000 for parkinsonism in Tehran, Iran could be considered a medium-to-high rate.

The marked shift in the patterns of drug use in Iran, from opium smoking to injecting drug use, has led to serious health-related outcomes. This study was designed to explore characteristics of people who inject drugs (PWID) in Tehran, Iran. Nine hundred and four PWID were recruited from treatment and harm reduction facilities, as well as drug user hangouts in public areas in Tehran. Participants were interviewed using the Persian version of the World Health Organization Drug Injecting Study Phase II questionnaire. The median age at the time of the first illegal drug use, at the time of the first injection and current age was 20, 24 and 32, respectively. In more than 80% of the cases, the first drug used was opium. The transition from the first drug use to the first drug injection occurred after an average of 6.6 and 2.7 years for those who had started drug use with opium and heroin, respectively. Two-thirds of the participants shared injecting equipment within the last 6 months. Difficulty in obtaining sterile needles and thehigh cost of syringes were reported as the major reasons for needle/syringe sharing. Approximately 80% of community-recruited PWID reported difficulties in using treatment or harm reduction services. Self-detoxification and forced detoxification were the most common types of drug abuse treatment in alifetime. Despite a dramatic shift in drug policy in Iran during the past few years, wider coverage of harm reduction services, improvement of the quality of services, and education about such services are still necessary.

Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both transmitted by the fecal-oral route and are known as the leading causes of acute viral hepatitis in the world, especially in developing countries. There is a lack of updated data on HAV and HEV seroprevalence in Iran. The aim of this study was to determine the seroprevalence of HAV and HEV among a group of blood donors in Tehran, Iran. A cross-sectional study was performed from July 2014 to December 2014, on a total of 559 blood donors referred to the Tehran blood transfusion center. The serum samples were tested for antibodies to HAV and HEV, using the enzyme-linked immunosorbent assay. In the present study, 536 (95.9%) cases were male and 23 (4.1%) female with mean age of 38 years. Out of 559 blood donors, 107 (19.1%) were first-time donors, 163 (29.2%) lapsed donors and 289 (51.7%) regular donors. Anti-HAV was found in 395 (70.7%) and anti-HEV in 45 (8.1%) of the blood donors. The HAV and HEV seroprevalence increased by age. There was no significant difference between genders in terms of anti-HAV and anti-HEV status. The HAV and HEV seroprevalence was significantly related to the level of education, where the donors with higher level of education had lower rate of HAV and HEV seroprevalence. The HAV and HEV seroprevalence was significantly higher in regular and lapsed donors than in first-time donors. The present study showed that both HAV and HEV infections are still endemic in Iran.

Fair distribution of hospital beds across various regions is a controversial subject. Resource allocation in health systems rarely has focused on those who need it most and, in addition, is often influenced by political interests. The study assesses the distribution of hospital beds in different regions in Tehran, Iran, during 2010-2012. This cross-sectional study was conducted in all regions of Tehran (22 regions) during 2010 to 2012. All hospital beds in these regions are included in the study. Data regarding populations of each region were obtained from the Statistics Center of Iran. According to the data, the total number of beds (N.B) and population (P) in 2010 (N.B=19075, P= 7585000), 2011 (N.B=21632, P= 9860500), and 2012 (N.B=21808, P=12818650). The instrument was a form, including the name of the hospital, the district in which the hospital was located, the number of staffed beds, the name of each region, and its population. Data analysis was performed using DASP software version 2.3. The results demonstrate that the Gini coefficient of distributed beds in 22 regions of Tehran was 0.46 in all three years and specifically calculated 0.4666 in 2010, 0.4658 in 2011 and 0.4652 in 2012. The Gini coefficient of beds in 22 regions of Tehran is not fair in comparison with the population of each region during the years 2010 to 2012. The results demonstrate that the distribution of beds in regions in Tehran is not fair in relation to the population of each region-and some regions had no hospitals. Therefore, it is essential for policymakers to frequently monitor this issue and investigate the fair distribution of hospital beds.

Mental health is of special importance regarding socioeconomic inequalities in health. On the one hand, mental health status mediates the relationship between economic inequality and health; on the other hand, mental health as an "end state" is affected by social factors and socioeconomic inequality. In spite of this, in examining socioeconomic inequalities in health, mental health has attracted less attention than physical health. As a first attempt in Iran, the objectives of this paper were to measure socioeconomic inequality in mental health, and then to untangle and quantify the contributions of potential determinants of mental health to the measured socioeconomic inequality. In a cross-sectional observational study, mental health data were taken from an Urban Health Equity Assessment and Response Tool (Urban HEART) survey, conducted on 22 300 Tehran households in 2007 and covering people aged 15 and above. Principal component analysis was used to measure the economic status of households. As a measure of socioeconomic inequality, a concentration index of mental health was applied and decomposed into its determinants. The overall concentration index of mental health in Tehran was -0.0673 (95% CI = -0.070 - -0.057). Decomposition of the concentration index revealed that economic status made the largest contribution (44.7%) to socioeconomic inequality in mental health. Educational status (13.4%), age group (13.1%), district of residence (12.5%) and employment status (6.5%) also proved further important contributors to the inequality. Socioeconomic inequalities exist in mental health status in Iran's capital, Tehran. Since the root of this avoidable inequality is in sectors outside the health system, a holistic mental health policy approach which includes social and economic determinants should be adopted to redress the inequitable distribution of mental health.

Many studies have recognized the importance of sexual and injection risk behaviors in HIV transmission among people who inject drugs (PWID). We aimed to examine effect of alcohol use on sexual and injection risky behavior using coarsened exact matching (CEM) approach among PWID in Tehran, Iran. A cross-sectional study. This study was conducted from Mar to Aug 2016 in Tehran, Iran. PWID were recruited by a convenience and snowball sampling from five of Drop-in Centers (DICs) in Tehran. We assessed three outcomes of interest, all treated as binary variables, including distributive and receptive sharing and inconsistent condom use with any type of sexual partner. We applied coarsened exact matching (CEM) to estimate the independent effect of alcohol use on injection and sexual risk behaviours. All data analysis was performed using Stata v.11. Overall, 550 PWID (all male) were enrolled. The prevalence of receptive sharing, distributive sharing, and inconsistent condom use was 32%, 15% and 55%, respectively. In the matched samples, last month drinkers were more likely to report receptive sharing (OR=2.12 95% CI: 1.31, 3.81; P=0.022), as compared to abstainer participants. Distributive sharing in last 30 d, was also significantly higher among last month drinkers group (OR=2.72 95% CI 1.72, 4.21; P=0.011), compared last month abstainers group. Finally, there was a statistically significant relationship between alcohol use and inconsistent condom use (OR=4.21 95% CI: 2.71, 7.52; P=0.013). The findings emphasize importance of addressing alcohol use in risk reduction interventions for Iranian PWID with alcohol use.

To our knowledge, no previous study has systematically assessed the role of economic status in risky sexual behavior among people who inject drugs (PWID) in Iran. In this study, we used Blinder-Oaxaca (BO) decomposition to explore the contribution of economic status to inequality in unprotected sex among PWID in Tehran and to decompose it into its determinants. Behavioral surveys among PWID were conducted in Tehran, the capital city of Iran, from November 2016 to April 2017. We employed a cross-sectional design and snowball sampling methodology. We constructed the asset index (weighted by the first principal component analysis factor) using socioeconomic data and then divided the variable into 3 tertiles. We used the BO method to decompose the economic inequality in unprotected sex. Of the 520 recruited individuals, 20 were missing data for variables used to define their economic status, and were therefore excluded from the analysis. Not having access to harm reduction programs was the largest factor contributing to the economic disparity in unprotected sex, accounting for 5.5 percentage points of the 21.4% discrepancy. Of the unadjusted total economic disparity in unprotected sex, 52% was unexplained by observable characteristics included in the regression model. The difference in the prevalence of unprotected sex between the high-income and low-income groups was 25%. Increasing needle syringe program coverage and improving human immunodeficiency virus (HIV) knowledge are essential for efforts to eliminate inequalities in HIV risk behaviors among PWID.

Background: This study was conducted to determine the total expenditure and out of pocket payment on pregnancy complications in Tehran, the capital of Iran. Methods: A cross-sectional study conducted on 1172 patients who admitted in two general teaching referral Hospitals in Tehran. In this study, we calculated total and out of pocket inpatient costs for seven pregnancy complications including preeclampsia, intrauterine growth restriction (IUGR), abortion, ante-partum hemorrhage, preterm delivery, premature rupture of membranes and post-dated pregnancy. We used descriptive analysis and analysis of variance test to compare these pregnancy complications. Results: The average duration of hospitalization was 3.28 days and the number of visits by physicians for a patient was 9.79 on average. The average total cost for these pregnancy complications was 735.22 Unites States Dollars (USD) (standard deviation [SD] = 650.53). The average out of packet share was 277.08 USD (SD = 350.74), which was 37.69% of total expenditure. IUGR with payment of 398.76 USD (SD = 418.54) (52.06% of total expenditure) had the greatest amount of out of pocket expenditure in all complications. While, abortion had the minimum out of pocket amount that was 148.77 USD (SD = 244.05). Conclusions: Obstetrics complications had no catastrophic effect on families, but IUGR cost was about 30% of monthly household non-food costs in Tehran so more financial protection plans and insurances are recommended for these patients.

Background: There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Methods: Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Results: Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). Conclusion: This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal. PMID:27799973

The present study assessed the prevalence of adverse drug reactions (ADRs) among HIV positive patients taking antiretroviral therapy referred to Imam Khomeini Hospital in Tehran, Iran. This is a cross sectional study regarding side effects of Highly Active Antiretroviral Therapy (HAART) in HIV positive patients referred to Voluntary Counseling and Testing (VCT) center in Imam Khomeini Hospital of Tehran, Iran during a period of the year 2009 to 2010. Two hundred patients under antiretroviral treatment evaluated for the side effects of drug based on available records, face to face interviews and written lab data. Data was collected from a sample of 200 HIV positive patients (72% male). Injection drug use was the most common route of HIV transmission. Co-Infections with Hepatitis C virus (HCV) found in the majority of patients (60.5%). Tuberculosis was the most prevalent opportunistic infection. One hundred eighty eight (94%) patients experienced at least one adverse drug reaction. The most frequent clinical and paraclinical findings were skin rash (28%) and abnormal liver function tests (36%). Given the high prevalence of adverse drug reactions among HIV positive patients taking antiretroviral therapy (ART) in this study, clinicians should be aware of ADRs at the initiation of ART as complications can affect patients' adherence to the therapy.

2016-01-01

OBJECTIVES Increasing interest has emerged in the use of subjective well-being as a development indicator and for the evaluation of public policies. The aim of this study was to assess life and health satisfaction and their determinants in the adult population of Iran. METHODS We conducted a survey of a sample of 3,150 adults at least 18 years of age in Tehran, the capital of Iran. The subjects were selected using a stratified random sampling method, and they were interviewed face-to-face at their usual residence by trained interviewers. Life satisfaction was used as a measure of subjective well-being. We used ordinary least square regression models to assess the associations of life and health satisfaction with socio-demographic variables. RESULTS On a 0-10 scale, the mean (standard deviation) scores for life and health satisfaction were 6.93 (2.54) and 7.18 (1.97), respectively. The average score for life satisfaction in females was 0.52 points higher than in males. A U-shaped relationship was found between age and life satisfaction, with respondents 35 to 44 years of age having the lowest average level of life satisfaction. Satisfaction with life and health among divorced respondents was significantly lower than among never-married and married participants. The scores for life satisfaction in respondents who rated their health status as poor were 3.83 points lower than in those who rated their health status as excellent. CONCLUSIONS The majority of the population of Tehran was satisfied with their life and health. Self-rated health status had the greatest impact on life satisfaction. PMID:27809456

Background: Social capital has been defined as norms, networks, and social links that facilitate collective actions. Social capital is related to a number of main social and public health variables. Therefore, the present study aimed to determine the factors associated with social capital among the residents of Tehran, Iran. Methods: In this large cross-sectional population-based study, 31531 residents aged 20 years and above were selected through multi-stage sampling method from 22 districts of Tehran in 2011. The social capital questionnaire, 28-item General Health Questionnaire (GHQ-28), and Short-Form Health Survey (SF-12) were used. Hypothetical causal models were designed to identify the pathways through which different variables influenced the components of social capital. Then, path analysis was conducted for identifying the determinants of social capital. Results: The most influential variables in 'individual trust' were job status (β=0.37, p=0.02), marital status (β=0.32, p=0.01), Physical Component Summary (PCS) (β=0.37, p=0.02), and age (β=0.34, p=0.03). On the other hand, education level (β=0.34, p=0.01), age (β=0.33, p=0.02), marital status (β=0.33, p=0.01), and job status (β=0.32, p=0.01) were effective in 'cohesion and social support'. Additionally, age (β=0.18, p=0.02), PCS (β=0.36, p=0.01), house ownership (β=0.23, p=0.03), and mental health (β=0.26, p=0.01) were influential in 'social trust/collective relations'. Conclusion: Social capital can be improved in communities by planning to improve education and occupation status, paying more attention to strengthening family bonds, and provision of local facilities and neighborhood bonds to reduce migration within the city.

The main objective of this study was to analyze the sensitivity of the monthly reference crop evapotranspiration (ETo) trends to key climatic factors (minimum and maximum air temperature ( T max and T min), relative humidity (RH), sunshine hours ( t sun), and wind speed ( U 2)) in Iran by applying a qualitative detrended method, rather than the historical mathematical approach. Meteorological data for the period of 1963-2007 from five synoptic stations with different climatic characteristics, including Mashhad (mountains), Tabriz (mountains), Tehran (semi-desert), Anzali (coastal wet), and Shiraz (semi-mountains) were used to address this objective. The Mann-Kendall test was employed to assess the trends of ETo and the climatic variables. The results indicated a significant increasing trend of the monthly ETo for Mashhad and Tabriz for most part of the year while the opposite conclusion was drawn for Tehran, Anzali, and Shiraz. Based on the detrended method, RH and U 2 were the two main variables enhancing the negative ETo trends in Tehran and Anzali stations whereas U 2 and temperature were responsible for this observation in Shiraz. On the other hand, the main meteorological variables affecting the significant positive trend of ETo were RH and t sun in Tabriz and T min, RH, and U 2 in Mashhad. Although a relative agreement was observed in terms of identifying one of the first two key climatic variables affecting the ETo trend, the qualitative and the quantitative sensitivity analysis solutions did never coincide. Further research is needed to evaluate this interesting finding for other geographic locations, and also to search for the major causes of this discrepancy.

Women's work and health in Iran: a comparison of working and non-working mothers.

2002-03-01

This paper analyses research on the impact of work on mothers' health in Tehran (Iran) within a role analytic framework. A survey was conducted of a representative sample of working and non-working mothers in Tehran in 1998 (N = 1065, 710 working mothers, and 355 non-working mothers). Three main explanatory factors were examined (socio-demographic, work and work-related, and social-life context variables) alongside a range of mental and physical health outcome variables. Unlike in the West, where women's paid work is generally associated with better health, statistically significant differences between working and non-working women were not found in Tehran. It is argued that this is a result of the counter-balance of the positive and negative factors associated with paid work, such as increased stress on one hand and self-esteem on the other. Iranian society's particular socio-cultural climate has contributed to this finding, with its dominant gender-role ideology; the priority and extra weight placed on women's traditional roles as wives and mothers, and the remarkably influential impact of husbands' attitudes on women's health.

This paper presents the findings of study undertaken to estimate the dietary intake of iron (Fe), copper (Cu), calcium (Ca) and zinc (Zn) through common cereals in Tehran, Iran. 100 samples of rice, wheat and barley were collected from various brands between August and October 2013. The samples were analyzed performing instrumental neutron activation analysis (INAA). The dietary intake for adults was estimated by a total cereal study. Calculations were carried out on the basis of the reported adults' average food consumption rate data. The total daily intake estimated in mgd(-1) for Tehran population were 3.6 (Fe), 10.2 (Zn), 0.3 (Cu) and 234.5 (Ca). Wheat showed the highest contribution to Zn, Cu and Ca intakes. Furthermore, intakes were compared with recommended dietary allowance (RDA). Zn total intake (10.2mgd(-1)) was comparable with RDA values for males (11mgd(-1)) and was higher than recommended value for females (8mgd(-1)). The intakes of other studied elements were below the respective RDAs. Copyright © 2014 Elsevier Ltd. All rights reserved.

In recent years, much attention has been paid to occupational stress, but relatively little or no research has been conducted on the influence of knowledge, attitude, and practice of radiation protection (RP-KAP) on job stress among radiation workers. This study aims to assess job stress among health care workers in Iran who are occupationally exposed to radiation in order to determine the effects of KAP on self-protection against radiation on their job stress. The population in this descriptive cross-sectional study comprised 670 healthcare workers, including 428 staff with a degree in radiology and 242 other medical personnel who were working in 16 hospitals affiliated with Tehran University of Medical Sciences (TUMS) in Tehran, Iran. The census method was used to sample the workers. In total, 264 staff with a degree in radiology and 149 other medical personnel completed the job content questionnaire (JCQ) and the RP-KAP questionnaire from May to November 2014. The prevalence rate of job stress was 22.5% based on calculation formulas and possible scores on the JCQ. Sex, RP-knowledge, attitude, practice, and in-service training predicted 41.8% of the variance in job stress. According to the results of the binary logistic regression, workers with higher scores on knowledge (OR = 0.82, 95% CI: 0.75 - 0.90), attitude (OR = 0.71, 95% CI: 0.63 - 0.82), and practice (OR = 0.78, 95% CI: 0.72 - 0.86) and those who had participated in training programs had significantly lower rates of job stress (OR = 0.51, 95% CI: 0.28 - 0.93). The effects of RP knowledge, attitude, and practice on job stress were significant. In order to reduce job stress in radiation environments, ongoing training programs related to self-care and protection principles are recommended.

The aim of this study was to design pictorial key and taxonomic literature of Culex pipiens complex in Iran. Larvae were collected using standard dipping methods in 13 randomly selected areas of Bushehr, Hamedan, Kerman, Khorasan-e-Razavi, Khuzistan, Mazandaran, Tehran, Sistan and Baluchistan and Yazd Provinces from April 2009 to October 2010. The data were analyzed using SPSS Ver. 11.5. Culex pipiens larvae were identified based on the Seta 1 of the abdominal segments III-IV in north and central parts of Iran. This diagnostic character had some variation among the Cx. quinquefasciatus collected from south of the country. The identification value of intersection of costa, subcosta and bifurcation of R2+3 of female veins, was calculated as 90-100 % for Cx. pipiens. This diagnostic character was varied among the Cx. quinquefasciatus specimens. The male genitalia found as the main characters to distinguish of Cx. quinquefasciatus from Cx. pipiens. It is necessary more studies on the behavior and genetic variations of Cx. pipiens complex in Iran.

Renewable energy has less negative impacts on environment than fossil fuels. Iran has many resources for renewable energy exploitation but because of their high price, it has not been developed. Site selection is an important step for utilizing large investments like solar farms and wind turbines. Multi-criteria evaluation methods are commonly used for site selection. The purpose of this paper is to determine suitable sites for solar farm and wind turbine using GIS and AHP in Tehran, in order to generate a distributed network to increase power network stability. The final land suitability index was grouped in four categories as "most suitable", "suitable", "moderate" and "low suitable". As a result 94.61% (789939.63 km2) is low suitable, 4.47% (37337.17 km2) is moderate, 0.59% (4964.22 km2) is suitable and 0.32% (2680.70 km2) is the most suitable for building wind turbine and for solar farm, 44.07% (8116.88 km2) is low suitable, 12.81% (2359.79 km2) is moderate, 35.10% (6464.29 km2) is suitable and 8.02% (1477.28 km2) is the most suitable.

Background Antimicrobial resistance (AMR) adversely impacts the prevention and treatment of a wide range of infections and is considered as a serious threat to global public health. Occupational-related AMR is a neglected area of research. Objective To assess exposure to penicillin dust, penicillin active materials, and to report the frequency of penicillin resistance among pharmaceutical workers in Tehran, Iran. Methods A quasi-experimental study was conducted among workers on a penicillin production line in a pharmaceutical company (n = 60) and workers in a food producing company (n = 60). Data were collected via survey, air sampling, and throat swab. Results The mean overall concentrations of penicillin dust and penicillin active material were 6.6 and 4.3 mg/m3, respectively, in the pharmaceutical industry. Streptococcus pneumoniae (S. pneumoniae) was detected in 45% (27) individuals in the exposed group, 92.6% of which showed penicillin resistance. Resistance was significantly higher among workers in penicillin production line (p = 0.014). Conclusions High level of AMR among workers in penicillin production line is a health risk for the workers as well as society as a whole through the spread of drug resistant micro-organisms.

There are geographical variations in Helicobacter pylori virulence genes; cagA, cagE, vacA and oipA. The present study compared the distribution of these genotypes in major ethnic groups residing in Tehran, Iran and their association with clinical outcomes. A total of 124 H. pylori-positive patients living in Tehran were enrolled in this study. The ethnic distribution was 74 Persians, 33 Turks and 17 other ethnics including Kurds, Lurs, Afghanis and Arabs. The presence of the cagA, cagE and oipA genes and vacA alleles (signal [s] and middle [m] region) were determined by polymerase chain reaction (PCR) from H. pylori DNA. The cagA-positive status was predominant in all three ethnic groups (e.g. 65% in Persians and 73% in Turks). In contrast, the cagE-positive status was less than half in Persians (47%) and Turks (30%), whereas it was 77% in other ethnicities (P = 0.008). The predominant vacA genotypes were s1 and m1 in all three ethnic groups (e.g. 68% in Persians and 70% in Turks were s1). There was no significant association between cagA and cagE status or vacA genotypes and clinical outcomes. The oipA-positive strains were more common in non-ulcer dyspepsia (NUD) (63%) than in peptic ulcer patients (15%) (P = 0.001) in Persians, but the association was not observed in other ethnic groups. There are some differences in the H. pylori genotypes among the ethnic groups in Iran. However, none of these markers seemed to be clinically helpful in predicting the clinical presentation of a H. pylori infection in Iran.

Introduction Given the increasing importance of disaster preparedness in Tehran, the capital of Iran, interventions encouraging disaster preparedness behavior (DPB) are needed. This study was conducted to show how an elicitation method can be used to identify salient consequences, referents, and circumstances about DPB and provide recommendations for interventions and quantitative research. A theory-based qualitative study using a semi-structured elicitation questionnaire was conducted with 132 heads of households from 22 districts in Tehran, Iran. Following the Theory of Planned Behavior (TPB), six open-ended questions were used to record the opinion of people about DPB: advantages of engaging in DPB; disadvantages of doing so; people who approve; people who disapprove; things that make it easy; and things that make it difficult. Content analysis showed the categories of salient consequences, reference groups, and circumstances. The three most frequently mentioned advantages obtained from inhabitants of Tehran were health outcomes (eg, it helps us to save our lives, it provides basic needs, and it protects us until relief workers arrive); other salient advantages were mentioned (eg, helps family reunification). The main disadvantage was preparedness anxiety. Family members were the most frequently mentioned social referent when people were asked who might approve or disapprove of their DPB. The two main circumstances perceived to obstruct DPB included not having enough knowledge or enough time. The results of this qualitative study suggest that interventions to encourage DPB among Tehran inhabitants should address: perceived consequences of DPB on health and other factors beyond health; barriers of not having enough knowledge and time perceived to hinder DPB; and social approval. More accurate research on salient beliefs with close-ended items developed from these open-ended data and with larger sample sizes of Tehran inhabitants is necessary. Research with other stakeholder groups is needed to understand their perceptions about DPB in creating the people's social environment. Najafi M , Ardalan A , Akbarisari A , Noorbala AA , Elmi H .

The use of the social marketing approach for public health issues is increasing. This approach uses marketing concepts borrowed from the principles of commercial marketing to promote beneficial health behaviors. In this qualitative study, four focus groups involving 42 participants were used in consumer research to explore taxi drivers' views on the driving situation and the determinants of risky driving behaviors in Tehran, as well as to gather their ideas for developing a social marketing program to reduce risky driving behaviors among taxi drivers in Tehran, Iran. Participants were asked to respond to questions that would guide the development of a marketing mix, or four Ps (product, price, place and promotion). The discussions determined that the program product should involve avoiding risky driving behaviors through increased attention to driving. They pointed out that developing and communicating with a well-designed persuasive message meant to draw their attention to driving could affect their driving behaviors. In addition, participants identified price, place and promotion strategies. They offered suggestions for marketing nonrisky driving to the target audience. The focus group discussions generated important insights into the values and the motivations that affect consumers' decisions to adopt the product. The focus group guided the development of a social marketing program to reduce risky driving behaviors in taxi drivers in Tehran, Iran. Copyright © 2010 Elsevier Ltd. All rights reserved.

Population based estimates of non-fatal injuries in the capital of Iran

PubMed Central

2011-01-01

Background Fatal injuries are at the top of the injury pyramid; however, non-fatal injuries are quite common and impose huge medical expenses on the population. Relying on hospital data will underestimate the incidence of non-fatal injuries. The aim of this study was to estimate the annual incidence and out of pocket medical expenses of all injuries in urban population of Tehran (the capital city of Iran). Methods Using the cluster random sampling approach, a household survey of residents of greater Tehran was performed on April 2008. At randomly selected residential locations, interviewers asked one adult person to report all injuries which have occurred during the past year for all household members, as well as the type of injury, place of occurrence, the activity, cause of accidents resulting in injuries, the amount of out of pocket medical expenses for injury, and whether they referred to hospital. Results This study included 2,450 households residing in Tehran during 2007-8. The annual incidence of all injuries was 188.7 (180.7-196.9), significant injuries needing any medical care was 68.8 (63.7-74.2), fractures was 19.3 (16.6 - 22.4), and injuries resulted in hospitalization was 16.7 (14.2 - 19.6) per 1000 population. The annual incidence of fatal injuries was 33 (7-96) per 100,000 Population. In children aged 15 or less, the annual incidence of all injuries was 137.2 (120.0 - 155.9), significant injuries needing any medical care was 64.2 (52.2 - 78.0), fractures was 21.8 (15.0 - 30.7), and injuries resulted in hospitalization was 6.8 (3.3 - 12.5) per 1000 population. The mean out of pocket medical expense for injuries was 19.9 USD. Conclusion This population based study showed that the real incidence of non-fatal injuries in the capital of Iran is more than the formal hospital-based estimates. These injuries impose non trivial medical and indirect cost on the community. The out of pocket medical expense of non-fatal injuries to Tehran population is estimated as 27 million USD per year. Effective strategies should be considered to minimize these injuries and decrease the great financial burden to public and the health system. PMID:21801449

Pharmacies as direct providers of medicine and pharmaceutical services to patients have an important role in the health status of a society. The assessment of their financial situations by healthcare policy makers is necessary to prevent any negative effects on population's health. In this study we aim to analyze the financial status of pharmacies in Tehran, Iran. This study is a cross-sectional study based on a survey. Two-hundred and eighty-eight private community daytime pharmacies in Tehran were selected by random sampling. We used two questionnaires to collect data regarding cost, expense and income factors of private pharmacies and the significance of each of them from these selected pharmacies. The data was collected in 2011 from Tehran pharmacies. Profitability of pharmacies in Tehran, Iran was calculated in its current situation and then estimated for three defined scenarios: 1. The dispensing fee is omitted (ceteris paribus), 2. Pharmacies are prohibited from selling hygienic & cosmetic products (ceteris paribus), 3. Scenarios 1 and 2 together (ceteris paribus). These data were analyzed by using SPSS and descriptive-analytic statistics. About 68% of interviewees responded to our questionnaires. Our analysis indicated that the average annual costs (and expenses), income and profits of pharmacies are 73,181; 106,301; and 33,120 United States Dollar (USD), respectively. The analysis indicated that omission of dispensing fee (scenario 1) and prohibition of pharmacies from selling hygienic & cosmetic products (scenario 2) would decrease income of pharmacies to 18438 and 14034 USD/year, respectively. According to respondents, the cost (or expense) of properties and buildings, energy, taxes, delays in reimbursement by insurance companies, and renting the place of pharmacy could be considered as cost factors and prescription medicines, OTC medicines, dispensing fees, hygienic & cosmetic products, and long-term payment to pharmaceutical distribution companies as income factors, which have significant effects on a pharmacy's economy. According to the results of this study, regarding the pharmacies' cost (and expenses) and incomes, the omission of dispensing fees for prescriptions has considerable negative effects on the profitability of pharmacies and likely on society's health.

The aim of this survey was to investigate the primary reason for extraction of permanent teeth, its correlations with age, gender and education level, as well as identify the important predictors for dental caries in general dental centers in Tehran, Iran. The study was conducted over a period of 6 months; its population consisted of 1,382 patients, aged 9-95 years, who underwent tooth extraction. There were 673 (47.8%) male and 709 (51.3%) female patients. The frequency distribution was calculated using the χ(2) test, ANOVA and t test for differences in mean number of extracted teeth and the logistic regression model to evaluate the variables associated with reasons for tooth extraction. A total of 2,620 teeth were extracted from the 1,382 patients. The highest rate (36.9%) of extraction occurred for those 41-60 years old. Males comprised 48.7% of patients but had more teeth (1,470, 55.3%) extracted than females (1,150, 43.9%). Nine hundred and thirty-six (67.7%) patients had incomplete secondary education or less. Tooth loss due to caries was 51%; periodontal disease was 14.4%; supernumerary and tooth impaction 13.9%. There was a significant association between patient characteristics (age, gender and education level) and number of teeth extracted. Dental caries and periodontal disease were the main reasons for tooth extraction in Tehran, Iran. Copyright © 2012 S. Karger AG, Basel.

Abstract Metal phosphides such as aluminum phosphide are potent insecticides. This highly toxic substance is used for rice and other grains protection in Iran. Due to its high toxicity potential and easy availability, it is widely used as a suicide poison. This substance has no effective antidote and the incidence of deaths due to its poisoning is increasing day by day in Iran. The present study was conducted to show the increasing incidence of fatal aluminum phosphide poisoning and its toxicological and forensic aspects in an 8-year study, 2006 to 2013. Autopsy sheets were reviewed and cases with the history of aluminum phosphide poisoning were selected. Toxicological analysis results, demographic and necroscopic examination findings were studied. A total of 51.8% of studied cases were female. Most of the cases were between 10 and 40 years old. The manner of death was self-poisoning in 85% of cases. Morphine, ethanol, and amitriptyline were the most common additional drugs detected in toxicological analysis. The incidence of fatal aluminum phosphide poisoning cases referred for phosphine analysis was 5.22 and 37.02 per million of population of Tehran in 2006 and 2013, respectively. The results of this study showed that in spite of ban and restrictions, there was a dramatic increase in the incidence of fatal aluminum phosphide poisoning in Tehran from 2006 to 2013. Safety alert should be highlighted in training program for all population groups about the toxic effects of aluminum phosphide tablets. PMID:26402837

Objective: Food choice is a process through which people think, feel, and eat food. It does not only influence individuals' health and well-being, families and communities, but also it has an effect on regional, national, and global levels. This qualitative study was conducted to explore perceptions and lived experiences of Tehran adult residents on psychological, social and cultural determinants of food choice. Method: In this qualitative design, we recruited 33 adults aged 30 to 64 years from various districts of Tehran, capital of Iran, and we explored how people make decisions about food choice in practice and shape their perception, attitude, and eating practices. An individual in-depth semi-structured interview guide included major questions with follow-up probes was used to explore participants’ current and past eating habits from childhood to adulthood, dietary change at different life courses, and effective psychological state on food selection in different seasons. Results: This study revealed that food choice in the studied adults (30-64 years old) was widely influenced by psychological, social, and cultural determinants, which can be categorized into 5 main themes: cultural context and patterns; social Structure and norms; information resources and media; household and family structure; and nutrition transition. Conclusion: The findings clarified the importance of social and cultural contexts, which influence the food choice of adults in a metropolis like Tehran. Many of these concepts are contextualized from childhood. These findings could serve as guideline to design socio-culturally appropriate strategies and improve dietary behaviors of Iranians.

Fireworks are used worldwide as a part of national and cultural celebrations. Personal use of fireworks is associated with serious injuries. The "Last Wednesday Eve Festival" is celebrated on the evening before the last wednesday of the Persian calendar year. In recent years, fireworks have been widely used during the festival, which has resulted in injuries. The aim of this study was to determine the incidence and risk factors of fireworks-related injuries associated with the Last Wednesday Eve Festival, in Tehran, Iran. A household survey of residents of greater Tehran, using a random cluster sampling design was performed. Number of fireworks-related injuries, expenditures for fireworks and medical treatment of fireworks-related injuries, length of hospital stay for treatment of these injuries and the personal property damage was gathered. Interviews were conducted of 2475 households in greater Tehran. At least one member of 19.8% of these households had used fireworks during the 2007 Last Wednesday Eve Festival. Fireworks-related injuries were more common among households whose members had used homemade fireworks than among households whose members had used only commercially made fireworks (OR=16.5, 95% CI: 5.7-47.5). Forty-five households reported that they had sustained personal property damage caused by fireworks during the festival, costing a mean of US$ 36.60. Households with at least one injured member spent a mean of US$ 441.90 for medical care and a mean of US$ 70.80 for other expenses related to seeking medical care. The overall incidence of fireworks-related injury among household members was 0.2% (95% CI: 0.1-0.3%). Fireworks-related injury incidence was highest in the 10-19 age group. The total estimated number of fireworks-related injuries in Tehran during the 2007 Last Wednesday Eve Festival was approximately 17,000. Among the 20 injured individuals, 4 persons (20.0%) were hospitalised for a mean of 2.8 days. The personal use of fireworks in Iran is associated with serious injuries and non-trivial economic costs. This study is the first to describe the incidence and economic costs of fireworks-related injuries in a major city in Iran using a population-based survey. To prevent these injuries, individuals should attend public fireworks displays conducted by professionals rather than engage in personal use of fireworks. 2009 Elsevier Ltd. All rights reserved.

Objective: In this study, we aimed to assess comparative productivity of 21 pharmaceutical companies in Iran during 2000–2013. Methods: To evaluate the productivity trend of pharmaceutical companies in Iran, we used data envelopment analysis-based Malmquist index. “Total assets” and “capital stock” as inputs and “net sales” and “net profit” as outputs extracted from Tehran stock exchange, were selected to be included in the analysis. This method provides the possibility for analyzing the performance of each company in term of productivity changes over time. We also used an estimation generalized least square panel data model to identify the factors that might affect productivity of pharmaceutical companies in Iran using EViews 7 and Deep 2.1 software. Findings: The mean total productivity during all years of the study was 0.9829, which indicates the improvement in their overall productivity. The results, over the 13-year period, indicated that the range of productivity changes in pharmaceutical companies, that were included in this study, was between 0.884 and 1.098. Panel data model indicated that age of company could positively (t = 4.765978, P < 0.001) and being located in cities other than Tehran (the capital) could negatively (t = −5.369549, P < 0.001) affect the productivity of pharmaceutical companies. The analysis showed the new policy (brand-generic scheme) and also the type of ownership did not have a significant effect on the productivity of pharmaceutical companies. Conclusion: In this study, pharmaceutical productivity trends were fluctuated that could be due to the sub-optimal attention of policy makers and managers of pharmaceutical companies toward long-term strategic planning, focusing on productivity improvement.

Keshtkar-Jahromi, Maryam; Sajadi, Mohammad M.; Ansari, Hossein; Mardani, Masoud; Naieni, Kourosh Holakouie

2014-01-01

The presence of Crimean-Congo hemorrhagic fever virus (CCHFV) in Iran was first identified in studies of livestock sera and ticks in the 1970s, but the first human infection was not diagnosed until 1999. Since that time, the number of cases of CCHF in Iran has markedly increased. Through January 2012, articles in the published literature have reported a total of 870 confirmed cases, with 126 deaths, for a case fatality rate (CFR) of 17.6%. The disease has been seen in 26 of the country’s 31 provinces, with the greatest number of cases in Sistan and Baluchestan, Isfahan, Fars, Tehran, Khorasan, and Khuzestan provinces. The increase in CCHF in Iran has paralleled that in neighboring Turkey, though the number of cases in Turkey has been much larger, with an overall CFR of around 5%. In this article, we review the features of CCHF in Iran, including its history, epidemiology, animal and tick reservoirs, current surveillance and control programs, diagnostic methods, clinical features and experience with ribavirin therapy, and consider possible explanations for the difference in the CFR of CCHF between Iran and Turkey. The emergence of CCHF in Iran calls for countermeasures at many levels to protect the population, but also provides opportunities for studying the epidemiology, diagnosis and management of the disease.

Background: Adolescence denotes a time in which youth begins to experience dangerous behaviors like substance use and delinquency. Objectives: In this study, we investigated the family power structure and identity style in delinquent and non-delinquent juveniles residing in Tehran, Iran. Materials and Methods: To accomplish the goal of the study, 80 adolescent delinquents of the correction and rehabilitation centers aged between 15 and 18 years were selected with convenience sampling method and 80 students of secondary school age between 15 and 18 years in Tehran, Iran in 2012. They answered the instrument of family power structure (Saidian, 2004) and identity style (ISI-6G: White et al. 1998). The obtained data were analyzed using the independent t-test, chi-square test, and Levene’s test. Results: The findings indicated a significant difference between delinquent and non-delinquent juveniles with regard to family power structure, its subscales (P < 0.001), and identity style (P < 0.001). Moreover, the informational identity style was associated with lower levels of delinquency. In addition, a diffuse-evident identity style was related to the delinquency. Conclusions: These results emphasize that the inappropriate decision-making process pattern in a family has a significant effect on deviant behavior and identity style in adolescents. So, family power structure can be considered in therapeutic interventions (prevention and treatment) for adolescent delinquency. PMID:26834795

Heavy metals and polycyclic aromatic hydrocarbons: pollution and ecological risk assessment in street dust of Tehran.

50 street dust samples from four major streets in eastern and southern Tehran, the capital of Iran, were analyzed for metal pollution (Cu, Cr, Pb, Ni, Cd, Zn, Fe, Mn and Li). Hakanson's method was used to determine the Risk Index (RI) and ecological risks. Amongst these samples, 21 were also analyzed for polycyclic aromatic hydrocarbons (PAHs). Correlation, cluster and principal component analyses identified probable natural and anthropogenic sources of contaminants. The dust had elevated concentrations of Pb, Cd, Cu, Cr, Ni, Zn, Fe and PAHs. Enrichment factors of Cu, Pb, Cd and Zn showed that the dust is extremely enriched in these metals. Multivariate statistical analyses revealed that Cu, Pb, Zn, Fe and PAHs and, to a lesser extent, Cr and Ni have common anthropogenic sources. While Mn and Li were identified to have natural sources, Cd may have different anthropogenic origins. All samples demonstrated high ecological risk. Traffic and related activities, petrogenic and pyrogenic sources are likely to be the main anthropogenic sources of heavy metals and PAHs in Tehran dust. Copyright © 2012 Elsevier B.V.

Background: Health-related quality of life is affected by electromagnetic field exposure in each person everyday life. However, this is extremely controversial issue. Objective: Investigation of the associations between electromagnetic field exposure and miscarriage among women of Tehran. Materials and Methods: In this longitudinal study, 462 pregnant women with gestational age <12 wks from seven main regions of Tehran city in Iran with similar social and cultural status were participated. Women were interviewed face-to face to collect data. Reproductive information was collected using medical file recorded in those hospitals the subjects had delivery. The measuring device measured electromagnetic waves, Narda safety test solutions with valid calibration date at the entrance door of their houses. Results: A significant likelihood of miscarriage in women who exposed to significant level of electromagnetic wave. However, this association was not confirmed by Wald test. Conclusion: This study may not provide strong or consistent evidence that electromagnetic field exposure is associated or cause miscarriage. This issue may be due to small sample size in this study.

The Totiviridae family includes a number of viruses that can infect protozoan parasites such as Leishmania and Giardia and fungi like Saccharomyces cerevisiae. Some isolates of Trichomonas vaginalis are also infected with one or more double-stranded RNA (dsRNA) viruses. In this study, the frequency of Trichomonas vaginalis virus (TVV1) was evaluated in Iranian isolates of T. vaginalis in Tehran, Iran. One thousand five hundred vaginal samples were collected from patients attending obstetrics and gynaecology hospitals associated with Iran University of Medical Sciences in Tehran, Iran from October 2015 to September 2016. Trichomonas vaginalis isolates were cultured in Diamond's modified medium. Nucleic acids were extracted using a DNA/RNA extraction kit and RT-PCR was performed. Among 1500 collected vaginal samples, 8 (0.53%) cases of T. vaginalis infection were found. Half (4/8) of the T. vaginalis positive cases were infected with TVV1. Phylogenetic mapping indicated that the Iranian isolates were most closely related to TVV1-OC5, TVV1-UR1. Iranian isolates of T. vaginalis were infected with TVV1. The frequency of viral infection (TVV1) in T. vaginalis isolates found in this study is higher than previously reported in Iran. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cervical cancer in women is one of the most common cancers and breast cancer has grown dramatically in recent years. The purpose of this study was to map the incidence of breast and cervix uteri cancer among Iranian women over a 6-year period (2004-2009) searching for trend changes and risk factors. Cancer incidence data were extracted from the annual reports of the National Cancer Registry in Iran. Hierarchical Bayesian models, including random spatial and temporal effects was utilized together with bivariate, spatio-temporal shared component modelling. The provinces Tehran, Isfahan, Mazandaran and Gilan were found to have the highest relative risk (RR) of breast cancer, while the highest RR of cervix uteri cancer was observed in Tehran, Golestan, Khuzestan and Khorasan Razavi. Shared risk factors (smoking component) between the two cancers were seen to have the highest influence in Tehran, Khorasan Razavi, Yazd, Isfahan, Golestan, Khuzestan, Fars and Mazandaran, while the least were observed in Kohgiluyeh Boyerahmad. Apparent differences and distinctions between high-risk and low-risk provinces reveal a pattern of obvious dispersion for these cancers in Iran that should be considered when allocating healthcare resources and services in different areas.

Uremic sarcopenia and dynapenia are prevalent in chronic kidney disease patients, including dialysis patients. The present study was designed to determine the prevalence of sarcopenia and dynapenia and their determinants in peritoneal dialysis (PD) patients in Tehran, Iran. All eligible PD patients at the peritoneal dialysis centers of Tehran were included in this cross-sectional study. Skeletal muscle mass and muscle strength were assessed using bioelectrical impedance analysis and hand grip strength, respectively. Physical performance was determined by a 4-m walk gait speed test. The prevalence rates of dynapenia and sarcopenia were 43.0% and 11.5% in the PD patients, respectively. There were significant associations between the prevalence of dynapenia and the age of patients (P = .03), physical activity level (P = .04), and the presence of diabetes mellitus (P = .005). In addition, a significant association was found between the prevalence of sarcopenia and sex (P = .009). This study indicates that uremic sarcopenia and dynapenia are prevalent in PD patients in Tehran, Iran. These conditions may contribute to physical disability, decreased the quality of life, increased morbidity, and a high mortality rate. Therefore, prevention and treatment of uremic sarcopenia and dynapenia are necessary for Iranian PD patients.

To investigate direct and stress-buffering associations between social support from family and the mental health of older people in Iran, a country which has recently undergone an exceptionally fast fertility transition and is consequently experiencing rapid population ageing. A cross-sectional stratified random survey of 800 people aged 60+ years resident in Tehran was conducted. In total, 644 people responded. The Social Provisions Scale and the General Health Questionnaire were used to measure perceived social support and mental health, respectively. Multilevel mixed-effects models were used to examine the hypotheses. The findings supported the hypothesis of a direct association between perceived and received social support and mental health. However, we did not find strong evidence to suggest that social support buffered the effects of stress arising from limitations of physical functioning. Lack of help doing paperwork was associated with worse mental health for women but not men. Source of support did not seem to be important. Our results indicated that in Tehran, as in Western settings, social support is important for the mental well-being of older people. Recommendations for policy and further research priorities based on the study findings were provided.

Large-scale atmospheric circulations associated with 133 moderate to heavy cold-weather precipitation events recorded at Mehrabad station in Tehran, Iran, during the period 1951-2013 are analysed. To this end, the performance of un-rotated, orthogonally rotated and obliquely rotated solutions of T-mode principal component analysis (PCA) is examined in classifying the atmospheric circulations into a few representative circulation types (CTs). The T-mode PCAs were applied to the 500-hPa geopotential height for the events in a domain from 10∘E to 70∘E and from 20∘N to 50∘N. The first six leading principal components were retained and then orthogonally and obliquely rotated using varimax and promax solutions, respectively. Statistical inter-comparison of the CTs obtained using the three solutions suggests that the obliquely rotated solution is the better choice for circulation classification in the present study. The six CTs obtained using the oblique rotation were then linked to the daily total precipitation and daily mean temperature variability at Tehran station as well as to the standardized anomalies of the daily total precipitation and mean daily temperature of a dense network of stations distributed across Iran. It is found that the CTs identified, though generally comparable in producing significant precipitation in Tehran, vary in their potential to bring cold weather and generate snowfall in Tehran specifically and in the country in general. While the first three CTs give rise to regional patterns of standardized precipitation anomalies centred in Tehran, the next three CTs leave a pronounced precipitation signature almost across the whole country. As regards the standardized temperature anomalies, with the exception of one CT that causes deep and widespread negative standardized anomalies over most parts of the country, the other CTs are characterized with a dipolar structure of a deep intrusion of cold weather to the west and prevailing warm weather to the east of the country.

Background: More than 20% of deaths from traffic crashes are related to pedestrians. This figure in Tehran, the capital of Iran, reaches to 40%. This study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in Tehran. Methods: Mapping was used to display the distribution of the crashes. Determining the distribution pattern of crashes and the hot spots/ low-risk areas were done, using Moran’s I index and Getis-Ord G, respectively. Results: A total of 198 crashes were studied; 92 of which, (46.4%) occurred in 2013 to 2014 and other 106 cases (63.6%) occurred in 2014 to 2015. The highest and the lowest frequency of crashes was related to January (26 cases) and June (10 cases), respectively. One hundred fifty- eight cases (79.8%) of crashes occurred in Tehran highways. Moran’s index showed that the studied traffic crashes had a cluster distribution (p<0.001). Getis- Ord General G index indicated that the distribution of hot and cold spots of the studied crashes was statistically significant (p<0.001). Conclusion: The majority of traffic crashes causing death to pedestrians occurred in highways located in the main entrances and exits of Tehran. Given the important role of environmental factors in the occurrence of traffic crashes related to pedestrians, identification of these factors requires more studies with casual inferences.

In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran). Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation data. In order to defining the composition of C&D waste, trucks were randomly selected and their wastes were separated and weighted. According to obtained results, about 82,646,051 m 3 of C&D waste (average 16,529,210 m 3 per year) were generated during 2011 to 2016 which only about 26% of them has been recycled. Mixing sand and cement, concrete, broken bricks and soil have the highest amount of the composition of C&D waste in Tehran that was 30, 19, 18 and 11%, respectively. Based on the results, about 2,784,158 t of the waste will generate in 2025 and this is approximately 122% higher than wastes generate in 2016. Based on MAPSA's data, 360 teams of personnel cruise and control the illegal disposals, but due to the expansion of Tehran this number of teams is inadequate and can't be effective in controlling the situation. In general, the overall condition of C&D waste management in Tehran seems undesirable and needs to be updated based on the experience of successful countries in this field.

The study aimed to assess 1) the attitudes of medical students in the sixth and seventh years (known as interns in Iran) toward psychiatry as a career choice, and 2) the degree of attractiveness of psychiatry as a career choice, with regard to various defined aspects, before and after an undergraduate psychiatry internship (similar to the medical school psychiatry rotation in the United States, but mandatory in Iran) in three major medical schools in Tehran, the capital of Iran. Sixth- and seventh-year medical students (locally called interns, N=347) at Tehran, Shahid Beheshti, and Iran Universities of Medical Sciences were consecutively invited to complete anonymous self-report questionnaires designed to assess their perceptions of careers in psychiatry before and after internship in psychiatry wards. Also, students evaluated psychiatry in terms of the factors that reflected the degree of attractiveness of this specialty. Positive responses toward choosing psychiatry as a career were seen in 18.8% before and 20.0% after psychiatry rotation. No significant differences were observed in the positive responses before and after psychiatry internship. The students' opinions changed to a more attractive degree in terms of only 3 out of the 13 defined aspects. There was also no significant difference in the total score on attractiveness of psychiatry before and after the psychiatry internship. The study indicated that undergraduate psychiatry internship might not induce more students to consider psychiatry as a possible career. The present pattern of psychiatry education in Iran seems not to positively affect most aspects of medical students' attitudes toward psychiatry.

The microbiological quality of 351 samples of nine types of spices including black pepper, caraway, cinnamon, cow parsnip, curry powder, garlic powder, red pepper, sumac, and turmeric, collected from retail shops in Tehran during 2007, was determined. The numbers of aerobic mesophilic bacteria, Escherichia coli, and molds exceeded Iran's National Standard limits, at 63.2% (>5 × 10(5) CFU/g), 23.4% (>0.3 MPN/g), and 21.9% (>5 × 10(3) CFU/g) of the studied samples, respectively. Coliform contamination was more than 10(3) MPN/g in 24.8% of samples. High contamination of retail spices is considered an indication of environmental or fecal contamination due to unhygienic practices in their production. Use of spices with high microbial content could increase the chance of food spoilage and transmission of foodborne pathogens. Accordingly, application of food safety measurements to reduce microbial counts in spices is strongly recommended.

Air pollution contains a complex mixture of poisonous compounds including particulate matter (PM) which has wide spectrum of adverse health effects. The main purpose of this study was to estimate the potential health impacts or benefits due to any changes in annual PM10 level in four major megacities of Iran. The required data of PM10 for AirQ software was collected from air quality monitoring stations in four megacities of Iran. The preprocessing was carried out using macro coding in excel environment. The relationship between different presumptive scenarios and health impacts was determined. We also assessed the health benefits of reducing PM10 to WHO Air Quality Guidelines (WHO-AQGs) and National Ambient Air Quality Standards (NAAQSs) levels with regard to the rate of mortality and morbidity in studied cities. We found that the 10 μg/m3 increase in annual PM10 concentration is responsible for seven (95% CI 6-8) cases increase in total number of deaths per 2 × 105 person. We also found that 10.7, 7.2, 5.7, and 5.3% of total death is attributable to short-term exposure to air pollution for Ahvaz, Isfahan, Shiraz, and Tehran, respectively. We found that by attaining the WHO's proposed value for PM10, the potential health benefits of 89, 84, 79, and 78% were obtained in Ahvaz, Isfahan, Shiraz, and Tehran, respectively. The results also indicated that 27, 10, 3, and 1% of health impacts were attributed to dust storm days for Ahvaz, Isfahan, Shiraz, and Tehran, respectively.

Objective: Perceived service quality is the most important predictor of patient satisfaction. The purpose of this study was to investigate the impact of the service quality on the overall satisfaction of patients in private hospitals of Tehran, Iran. Method: This cross-sectional study was conducted in the year 2010. The study’s sample consisted of 969 patients who were recruited from eight private general hospitals in Tehran, Iran using consecutive sampling. A questionnaire was used for data collection; contacting 21 items (17 items about service quality and 4 items about overall satisfaction) and its validity and reliability were confirmed. Data analysis was performed using t-test, ANOVA and multivariate regression. Result: this study found a strong relationship between service quality and patient satisfaction. About 45% of the variance in overall satisfaction was explained by four dimensions of perceived service quality. The cost of services, the quality of the process and the quality of interaction had the greatest effects on the overall satisfaction of patients, but not found a significant effect on the quality of the physical environment on patient satisfaction. Conclusions: Constructs related to costs, delivery of service and interpersonal aspect of care had the most positive impact on overall satisfaction of patients. Managers and owners of private hospitals should set reasonable prices compared to the quality of service. In terms of process quality, waiting time for visits, admissions, and surgeries must be declined and services provided at the fastest possible time. It should be emphasized to strengthen of interpersonal aspects of care and communication skills of care providers. PMID:25560338

Objective/background In patients with spinal cord injury (SCI), SCI causes psychosocial complications that vary based on culture, conditions, and the amenities of each community. Health planners and social services should have full knowledge of these issues in order to plan schedules that address them. In this study, we aimed to understand the psychosocial problems of persons with SCI in Iran and to explore the requirements for minimizing these difficulties. Design This was a descriptive cross-sectional study. Setting Brain and Spinal Cord Injury Research (BASIR) Center, Tehran University of Medical Sciences, Tehran, Iran. Participants One hundred nineteen persons with SCI referred to BASIR clinic to receive outpatient rehabilitation. Methods In this study, trained interviewers administered a questionnaire to the participants. The questionnaire consisted of socio-demographic variables and psychosocial questions about finances, employment, housing, education, and social communication problems. Results Psychosocial problems for persons with SCI are mainly associated with financial hardship due to unemployment and the high cost of living, followed by difficulties with transportation, house modification, education, marriage, social communication, sports, and entertainment. Psychological problems include sadness, depression, irritability/anger, suicidal thoughts, and a lack of self-confidence. The levels of the aforementioned problems differ with respect to sex. Conclusion Persons suffering from SCI can face some serious psychosocial problems that may vary according to sex. For example, transportation difficulties can lead to problems such as unsociability. After recognizing these problems, the next step would be providing services to facilitate a productive lifestyle, enhancing social communication and psychological health, and ultimately creating a higher quality of life.

Increasing interest has emerged in the use of subjective well-being as a development indicator and for the evaluation of public policies. The aim of this study was to assess life and health satisfaction and their determinants in the adult population of Iran. We conducted a survey of a sample of 3,150 adults at least 18 years of age in Tehran, the capital of Iran. The subjects were selected using a stratified random sampling method, and they were interviewed face-to-face at their usual residence by trained interviewers. Life satisfaction was used as a measure of subjective well-being. We used ordinary least square regression models to assess the associations of life and health satisfaction with socio-demographic variables. On a 0-10 scale, the mean (standard deviation) scores for life and health satisfaction were 6.93 (2.54) and 7.18 (1.97), respectively. The average score for life satisfaction in females was 0.52 points higher than in males. A U-shaped relationship was found between age and life satisfaction, with respondents 35 to 44 years of age having the lowest average level of life satisfaction. Satisfaction with life and health among divorced respondents was significantly lower than among never-married and married participants. The scores for life satisfaction in respondents who rated their health status as poor were 3.83 points lower than in those who rated their health status as excellent. The majority of the population of Tehran was satisfied with their life and health. Self-rated health status had the greatest impact on life satisfaction.

Background: Malnutrition and dehydration are two most common types of ailments residents of nursing homes (NH) prone to. It is very important to assess these problems because they can predispose the residents to severe illnesses. The aim of this study was to gather information on nutritional status and its associated risk factors in elderly residents of NHs in Tehran, Iran. Methods: From 16 NHs in Tehran, 263 residents were randomly selected. Data were collected via questionnaires, including demographic characteristics, past medical history, present health problems and daily routines. The MNA questionnaire was used to gather information regarding their nutritional status. Results: The present study showed that 10.3% of the elderly residents in nursing homes were malnourished. 66.4% of males and 70.8% of females were at risk of malnutrition. Multivariate analysis showed that after adjusting for confounders the following elderly-related factors were the independent risk factors of malnutrition: consuming half or less than of the food (OR=8.0, 95%CI=3.7–17.7), having no teeth or good prosthesis (OR=1.7, 95%CI=1.1–2.7), diabetes (OR=1.6, 95%CI=1.1–2.4), smoking (OR=0.6, 95%CI=0.3–1.2), studying (OR=0.4 95%CI=0.2–0.9) and praying in their free time (OR=1.8 95%CI=1.2–2.6). Conclusion: The subjects’ health-related factors and their free-time activities and nutritional behavior are the most important factors associated with poor nutrition among elderly residents of NHs; however, further investigation is needed to clarify the role of other factors in maintaining a suitable nutritional plan for them.

A cross-sectional study. This study was performed for epidemiological assessment of Iranian Traumatic Spinal Cord Injuries (TSCI), referred to a specialized spine center. Patient recruitment and evaluations were conducted at the Brain and Spinal Injury Research Center, Tehran, Iran. This study was performed from September 2011 to March 2015 on 1137 consecutive TSCIs. History, clinicoradiological findings as well as chronic complications and social integration were recorded. The capture-recapture method was used to calculate a rough estimation of TSCI prevalence in Tehran Province. Our report includes 1137 cases with a mean age of 29.1 years (s.d.=11.2 year)-79.2% of them being male (M/F=3.8/1). Rough estimation of TSCI prevalence in Tehran province was 2.36 per 10 000 population. Regarding etiology, 61.8% were due to motor vehicle accident (MVA), followed by falling 24.5%, heavy drop 5.2%, violence 3.8%, sport 2.8% and others causes 1.9%. Regarding injury level, 31.5% were cervical, 57.9% thoracic and 10.6% lumbar. Complete lesions were 53.5% of patients and 46.5% were incomplete. Most common neurological type was T1-S5 (American Spinal Injury Association Impairment Scale: A, B, C, 61.7%). Most common complications included urinary tract infection followed by pressure sore (grade III and IV, 37.5%), autonomic dysreflexia (37%) and neuropathic pain (31.2%). Substance abuse was observed in 8.8% of cases. Overall, ~25% in our cases were employed after TSCI. Secondary divorce was also much more frequent than normal matched controls. MVA was the most common cause for TSCI. The elderly subjects were less frequent among our patients than more developed countries. The high rate of unemployment and divorce in our cases deserves special consideration.

To assess smoking, tooth brushing and oral cleanliness and their relationships among 15-year-olds in Tehran, Iran. A cross-sectional study based on World Health Organization criteria and the methods of the Second International Collaborative Study was carried out in autumn 2004 among 15-year-olds (n=502) in Tehran. Data were based on a self-administered questionnaire and a clinical dental examination. Smokers comprised 5% of the boys and 2% of the girls (p = 0.02). Smoking was more common among students of less-educated parents (50% vs. 30%, p < 0.05). Of all students, 26% reported twice-daily tooth brushing; those of higher socio-economic backgrounds and girls did so more frequently. Of the smokers, 11% reported no tooth brushing compared to 6% of the non-smokers. Oral cleanliness was good for 13%, moderate for 32%, and poor for 55%; the rates associated positively with female gender (p = 0.002), having higher-educated parents (p = 0.03), and reporting a higher frequency of tooth brushing (p < 0.001). Those students reporting twice-daily tooth brushing had less dental plaque and gingival bleeding (p < or = 0.01) on both anterior and posterior teeth. In multivariable analyses, the best predictors for a good level of oral cleanliness were female gender (OR = 2.0) or twice-daily tooth brushing (OR = 1.7). Oral cleanliness and tooth brushing among 15-year-olds were at poor levels, particularly among boys. Such poor levels call for intensive attempts to enhance rates of twice-daily tooth brushing and to improve its quality. For this age group, anti-smoking purposes should be combined into school-based oral health promotion programmes as well.

Many couples in the Islamic Republic of Iran rely on coital withdrawal for contraception. The purpose of this cross-sectional study was to use the theory of planned behaviour to explore factors that influence withdrawal users' intent to switch to oral contraception (OC). Participants were 336 sexually active, married women, who were current users of withdrawal and were recruited from 5 public family planning clinics in Tehran. A questionnair included measures of the theory of planned behaviour: attitude (behavioural beliefs, outcome evaluations), subjective norms (normative beliefs, motivation to comply), perceived behaviour control, past behaviour and behavioural intention. Linear regression analyses showed that past behaviour, perceived behaviour control, attitude and subjective norms accounted for the highest percentage of total variance observed for intention to use OC (36%). Beliefs-based family planning education and counsellingshould to be designed for users of the withdrawal method.

The assessment of the gender and age-specific seroprevalence of human papillomavirus (HPV) is essential for planning of HPV vaccine implementation into the preventive programs. In this study, we aimed to determine the age-specific seroprevalence of HPV-16 and 18 in both males and females in Tehran, Iran. Three hundred and seventy-eight women (10-35 years) and 162 men (10-25 years) from Tehran, Iran, were enrolled. Anti-HPV IgG antibodies against HPV-16 and HPV-18 were detected by ELISA using papillomavirus type 16 and 18 L1-capsids as antigen. HPV-16 antibody was detected in 15.6 and 13.6% of women and men, respectively. Antibody against HPV-18 was found positive in 12.7 and 8% of women and men, respectively. The highest seroprevalence of HPV-16 and 18 were seen in women aged 26-30 years (22.2 and 19.4%, respectively), and the lowest HPV-16 and 18 seropositivity rates were seen in males and females aged 10-15 years (9.3 and 1.9%, respectively). In our cohort of study, in males, both anti-HPV-16 and 18 increased after age 15 years, peaking in men aged 21-25 years. In women, both HPV-16 and 18 seropositivity increased after 15 years, declined at 21-25 years, peaked in women aged 26-30 years and again decreased after 30 years. Our data showed increasing exposure rate to high-risk HPV vaccine types in our studied population over 15 years of age. In order to prevent the HPV-related cancers, implementation of HPV vaccine into the national immunization program in Iran and vaccination of females and males less than 15 years of age are suggested.

Tick-borne relapsing fever is an endemic disease in Iran, with most cases attributed to infection by Borrelia persica, which is transmitted by Ornithodoros tholozani soft ticks. Here, we report spirochetemia in blood of a puppy residing in Tehran, Iran. The causative species was identified by use of highly discriminative IGS sequencing; the 489 bp IGS sequence obtained in our study showed 99% identity (100% coverage) when compared with B. persica sequences derived from clinical cases or from O. tholozani ticks. Our IGS sequence also showed 99% similarity over 414 bp (85% coverage) with a strain from a domestic dog, and 96% over 328 bp (69% coverage) with a strain from a domestic cat. Pet-keeping in cosmopolitan cities like Tehran has become increasingly popular in recent years. Animals are often transported into the city in cages or cardboard boxes that might also harbor minute tick larvae and/or early stages of the nymphs bringing them into the urban environment. This may pose a threat to household members who buy and keep these puppies and as a result may come into close contact with infected ticks. Copyright © 2016 Elsevier GmbH. All rights reserved.

Determination of dust loading in the atmosphere is important not only from the public health point of view, but also for regional climate changes. The present study focuses on the characteristics of two major dust events for two urban areas in Iran, Kermanshah and Tehran, over the period of 4 years from 2006 to 2009. To detect extreme dust outbreaks, various datasets including synoptic data, dust concentration, reanalysis data and numerical results of WRF and HYSPLIT models were used. The weather maps demonstrate that for these events dusts are mainly generated when wind velocity is high and humidity is low in the lower troposphere and the region is under the influence of a thermal low. The event lasts until the atmospheric stability prevails and the surface wind speed weakens. The thermal low nature of the synoptic conditions of these major events is also responsible for deep boundary layer development with its thermals affecting the vertical dust flux over the region. Trajectory studies show that the dust events originated from deserts in Iraq and Syria and transported towards Iran. The main distinction between the two types of mobilizations seems to affect the dust concentrations in the Tehran urban area.

Eight months after the mass immunization campaign of November 2015 against measles and rubella in the southeast of Iran, in order to evaluate the sero-immunity level of the people living in the mentioned region, a serosurvey study was performed. Using a multi-stage probability proportional to size cluster sampling, the sera of 1,056 participants, ranging from 15 months to 20 years old, were tested for measles and rubella IgG antibodies in the National Reference Laboratory at Tehran University of Medical Sciences, Tehran, Iran. The seroprevalence rates of antibodies against measles and rubella in the age groups below 16 years were respectively 98.4 and 93.2%. In the age group of 16 to 20 years, who was not the target of the mass immunization campaign, the said rates were respectively 91.7% and 87.4%. The herd immunity of the age groups below 16 years, who were the target of the campaign, is favourably high and reassuring both for measles and for rubella. Campaigns of supplementary vaccination play a substantial role for filling the gaps in the herd immunity.

Gender and spatial population mobility in Iran.

Hemmasi, M

1994-01-01

1976-1986 data from the National Census of Population and Housing were analyzed to examine the spatial patterns of internal migration of women and men in Iran within its Islamic patriarchal cultural system. The researcher also organized 1986 data into two interprovincial migration matrixes for men and women. Women were spatially as mobile as men (urban, 16.7% for men and 17% for women; rural, 8.4% and 8.9%, respectively). Gender spatial mobility patterns during the 10 years included: migration streams from nine provinces consistently led to Tehran province, most migration flows to Tehran and most other provinces originated from Khuzistan, East Azerbaijan province still continued to lose population (about 500,000), and out-flows generally originated from the provinces affected by the Iran-Iraq war and went to the central and eastern provinces. The strongest determinants of women's migration was men's migration ratio and the road distance between the origin and destination. Reasons for these strong associations were few employed women ( 10%), strong family ties, and traditional cultural values (e.g., women tend not to travel alone). So their migration patterns tended to be associational rather than autonomous. Despite the fact that internal migration patterns of men and women were the same, the causes, processes, and consequences of migration were still very gender-specific in Iran. There are no signs of change in the near future.

Background: Overweight and obesity in children are a serious problem. They are increasingly prevalent and associated with a wide range of health problems in adulthood. Monitoring their status is essential for effective planning in the health system. Objectives: This study aimed to assess the prevalence of overweight and obesity in children below 5 years in Tehran in 2012. Patients and Methods: This cross-sectional study employed data provided by the urban health equity assessment in Tehran. The sample comprised a total of 4656 children under 5 years, recruited via multistage sampling. Data were collected through questionnaires and anthropometric measures of height and weight. The WHO child growth standards were used to determine overweight and obesity. Data were analyzed using chi-square tests, with SPSS version 11.5. Results: The prevalence of overweight and obesity in children were 12% and 23.7% respectively. The prevalence of overweight was significantly higher in girls than boys and the prevalence of obesity was significantly higher in boys than girls (P = 0.001). Obesity was more prevalent in children from high economic percentiles, but this finding was not statistically significant. Conclusions: The prevalence of overweight and obesity in children under 5 years is high. Overweight and obesity should be considered an epidemic and serious health problem in Tehran. They certainly require more attention and intervention. PMID:26889459

Background and Objective Carbapenems are therapeutic choice against infections caused by gram-negative bacilli including strains of Acinetobacter baumannii. Resistance to these antibiotics is mediated by efflux pumps, porins, PBPs and ß-lactamases. The aim of this study was to determine the possibility of existence of MBLs, OXAs and GES-1 betalactamase genes among clinical isolates of Acinetobacter collected from Tehran hospitals. Material and Methods Two hundred and three Acinetobacter isolates were collected from patient at Tehran hospitals. The isolates were identified using biochemical tests. The susceptibility to different antibiotics was evaluated by disk diffusion method and MICs of imipenem were determined using Micro broth dilution method (CLSI). PCR was performed for detection of bla VIM-2, bla SPM-1, bla IMP-2, bla GES-1, bla OXA-51, bla OXA-23 betalactamase genes. Clonal relatedness was estimated by PFGE with the restriction enzyme SmaI. Results and Conclusion Of 100 isolates of imipenem resistant Acinetobacter spp. collected from Tehran hospitals in 2009 and 2010, 6 isolates produced metallo-beta-lactamases and 94 isolates produced OXA-type carbapenemase. The bla SPM-1, bla GES-1, bla OXA-51, bla OXA-23 genes were detected by PCR among 6, 2, 94 and 84 isolates of A. baumannii, respectively. The MICs of isolates to imipenem were 8–128 µg/mL. PFGE analysis of 29 bla OXA-51 and bla OXA-23-positive A. baumannii isolates gave 6 different patterns. This is the first report of SPM-1 and GES-1 beta-lactamase producing A. baumannii. Production of the OXA-23, OXA-51, GES-1 and SPM-1 enzyme presents an emerging threat of carbapenem resistance among A. baumannii in Iran. PMID:22347585

Very few land use regression (LUR) models have been developed for megacities in low- and middle-income countries, but such models are needed to facilitate epidemiologic research on air pollution. We developed annual and seasonal LUR models for ambient oxides of nitrogen (NO, NO2, and NOX) in the Middle Eastern city of Tehran, Iran, using 2010 data from 23 fixed monitoring stations. A novel systematic algorithm was developed for spatial modeling. The R2 values for the LUR models ranged from 0.69 to 0.78 for NO, 0.64 to 0.75 for NO2, and 0.61 to 0.79 for NOx. The most predictive variables were: distance to the traffic access control zone; distance to primary schools; green space; official areas; bridges; and slope. The annual average concentrations of all pollutants were high, approaching those reported for megacities in Asia. At 1000 randomly-selected locations the correlations between cooler and warmer season estimates were 0.64 for NO, 0.58 for NOX, and 0.30 for NO2. Seasonal differences in spatial patterns of pollution are likely driven by differences in source contributions and meteorology. These models provide a basis for understanding long-term exposures and chronic health effects of air pollution in Tehran, where such research has been limited.

Iran has experienced an emerging epidemic of methamphetamine use during recent years which has added to existing non-injecting and injecting opioid use in the country. This study explored factors influencing the initiation into or transition to methamphetamine use among young people who use drugs (PWUD). We conducted 42 semi-structured, in-depth interviews with young PWUD (n = 35) and health care workers (HCWs) (n = 7) between July and October 2011 in Tehran, Iran. The PWUD were purposefully recruited from different tiers of drug services and lived in geographically diverse areas of Tehran. The HCWs were substance use experts and/or service providers of treatment and harm reduction facilities. All interviews were recorded, transcribed, and coded using OpenCode 3.6 software. The predominant factors for initiation into or transition to methamphetamine use were individual domain factors. The peer domain factors were the second most frequently stated perceived factor category for transition to methamphetamine use. Other perceived factors affecting transition to stimulant use included both family and community domains. Drug prevention programs should consider targeting certain settings, including workplaces and sports clubs, for preventative interventions. Existing opioid treatment and harm reduction services should be adjusted in response to the methamphetamine use epidemic.

Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran. In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014. The samples were examined by formalin-ether concentration, culture, and with molecular methods. The prevalence of enteric parasites was 32.7% (95% CI 27.3-38). Blastocystis sp. was the most common intestinal protozoan (28.4%; 95% CI 23.7-33.0). The formalin-ether concentration and culture methods detected Blastocystis sp., Entamoeba coli , Giardia intestinalis , Dientamoeba fragilis , Iodamoeba butschlii , Entamoeba complex cysts or trophozoite , Chilomastix mesnilii , and Enterobius vermicularis . Single-round PCR assay for Entamoeba complex were identified Entamoeba dispar and E. moshkovskii . E. histolytica was not observed in any specimen. Multivariate analysis showed a significant association of parasites with water source and close animal contact. There was no correlation between infections and gender, age, occupation, education, or travel history. Protozoan infections were more common than helminth infections. This study revealed a high prevalence of enteric protozoan parasite infection among citizens of Rodehen. As most of the species detected are transmitted through a water-resistant cyst, public and individual education on personal hygiene should be considered to reduce transmission of intestinal parasites in the population.

Background Sleep patterns may change over a person’s lifetime; however, the quantity and quality of sleep always depend on individual factors such as age, sex, and psychological and environmental factors. In children, sleep is as important as development. Quantitative sleep problems related to sleep onset and qualitative sleep disorders such as frequent awakenings may lead to insufficient sleep. Objectives This study aimed to assess the prevalence of sleep disorders among children 4 - 6 years old attending the health centers of Shahid Beheshti University of Medical Sciences, Tehran, Iran, in 2013. Patients and Methods This was a cross-sectional study on 400 children selected using a multistage sampling method. Data were collected by interviews. The questionnaire included two sections: a demographic section with questions about the demographic characteristics of the children and parents and a children’s sleep habit questionnaire (CSHQ). Data were analyzed by SPSS 16 and different statistical tests were used (P < 0.05). Results The mean age of the children was 64.27 ± 9.3 months. The prevalence of sleep disorders was 36.25%. Sleep disorders were significantly associated with age, height, body mass index, residence of children, father’s occupation, mother’s diseases, father’s drug abuse, and parents’ marital status (P < 0.05). Conclusions Sleep disorders in children threaten growth and development, and are dangerous for their health. Sleep disorders should be considered in the differential diagnosis of children’s learning and behavioral problems. PMID:27651942

Combined heart and kidney transplant has become an accepted therapy for patients with coexisting heart and kidney failure. This method, compared with single-organ transplant, has a better outcome. Here, we report the first successful combined heart and kidney transplant in Iran. The patient was a 36-year-old man with end-stage renal disease owing to IgA nephropathy, admitted to Masih Daneshvari Hospital in Tehran, Iran for progressive dyspnea and chest pain. In-patient evaluations revealed cardiomyopathy leading to end-stage heart failure. Owing to concurrent heart and kidney end-stage diseases, combined cardiorenal transplant was done. Eight months after his transplant, routine follow-ups have not shown any signs of acute rejection. He is now New York Heart Association functional class I. Both cardiac and renal functions are within normal ranges. Good outcome during follow-up for this case justifies simultaneous heart plus kidney transplants as an alternate treatment for patients with advanced disease of both organs.

Background: Although significant consideration has been devoted to women participation in breast cancer prevention programs, our understanding about the psychosocial factors which influence participation remains incomplete. Method: The study applied a quantitative approach based on the cross-sectional survey design and multistage cluster random sampling. A total of 400 women aged 35-69 years, were surveyed at 4 obstetric and gynecologic clinics affiliated to Tehran University of Medical Sciences in Tehran: the participation levels of 86 women who have had a mammogram were analyzed based on their self-efficacy, belief, social influence, and barriers concerning mammography utilization. Results: Consistent with the study framework, in bivariate analysis, the higher level of women’s participation in breast cancer prevention programs was significantly related to more positive belief about mammography (p< .05), greater social influence on mammography (p< .01) and fewer barriers to mammography (p< .01). Self efficacy (p= .114) was not significantly related to the higher level of participation. Conclusion: Results suggest that women’s participation levels in breast cancer prevention programs might be associated with the specific psychosocial factors on breast cancer preventive behavior such as mammography screening.

Background Despite cultural and religious prohibitions against premarital heterosexual relationships and intimacy, some recent evidence suggests some rise in premarital heterosexual interactions and relationships among young people. On the other hand, although HIV in Iran is a concentrated epidemic and mainly reported among high risk groups such as injecting drug users (IDUs), but there are evidences that the mode of transmission is shifting towards sexual contacts. This trend has caused concern among health policy makers in terms of prevention of STDs and HIV/AIDS particularly, among young people. This paper was prepared with the aim of highlighting how gender contributes to variation in reproductive health needs and conduct of young people in Iran. Method This paper is based on a secondary analysis and compares comparable reproductive beliefs and conducts of women and men based on the data of two surveys conducted in Tehran in 2002 and 2005. A survey among 1385 adolescent males and another survey among 1743 female undergraduate students in four multidisciplinary universities in Tehran. Both surveys used anonymous self-administered questionnaires. To make the two samples comparable, the data of unmarried female university undergraduate students who resided in Tehran were merged with the data of adolescent male students who intended to pursue higher education. Common variables of the two surveys were identified, homogenized, merged and analysed. Results Reproductive health knowledge among male adolescents was poor compared to that of their female peers. Although premarital friendships were moderately acceptable from view points of both males and females, the majority were against premarital sex, particularly among female participants. There were evidences of gender-based double standards in perceptions of premarital sexuality among both males and females; particularly, it was stronger among males than females. Male adolescents reported earlier and greater experiences of premarital heterosexual intimacy and sexual contact than females. Multiple partners were also more common among males than females. Females had a tendency to regret first sexual contact more than males, which reflects that first sex is more likely to be unplanned and unwanted among females compared to males. Conclusion Significant gender–based double standards prevailed current sexual attitudes and conduct of young people in Iran. Gender norms which encourage unmarried men to practice premarital sex lead to an earlier transition of men to sexual relations and multiple sexual partners. Due to poor knowledge and various misconceptions about sexual health and lack of consistent contraceptive and condom use among adolescents and young people in Iran, both young men and women are susceptible to sexual and reproductive health hazards such as sexually transmitted infections (STIs), HIV/AIDS, pregnancy and unsafe abortion. Changing gender norms associated with sexuality may lead to promotion of safer sexual behaviors particularly among young people. Current reproductive health and HIV prevention programs should take into account gender-based double standards among young people and their unmet reproductive health needs. PMID:23926532

The 12-item medical outcomes study short form health survey version 2.0 (SF-12v2): a population-based validation study from Tehran, Iran

PubMed Central

2011-01-01

Background The SF-12v2 is the improved version of the SF-12v1. This study aimed to validate the SF-12v2 in Iran. Methods A random sample of the general population aged 18 years and over living in Tehran, Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses (EFA and CFA). Results In all, 3685 individuals were studied (1887male and 1798 female). Internal consistency for both summary measures was satisfactory. Cronbach's α for the Physical Component Summary (PCS-12) was 0.87 and for the Mental Component Summary (MCS-12) it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status (P < 0.05). Furthermore, as hypothesized the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12, while the vitality, social functioning, role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 59.9% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). Conclusion Although the findings could not be generalized to the Iranian population, overall the findings suggest that the SF-12v2 is a reliable and valid measure of health related quality of life among Iranians and now could be used in future health outcome studies. However, further studies are recommended to establish its stability, responsiveness to change, and concurrent validity for this health survey in Iran. PMID:21385359

Epilepsy is a prototypical, stigmatised disorder. Numerous studies have been conducted regarding the public perception of epilepsy, but they are primarily from high-income western countries; few studies have taken place in low- to middle-income countries with a traditional culture and a religious orientation. The public knowledge and attitudes towards epilepsy in Tehran, Iran, is studied. A survey of 800 subjects ranging from 18 to 85 years was randomly chosen from households in Tehran in 2009. The questionnaire used was based on the Caveness and Gallup's studies conducted in the United States in 1949 and it has been used in numerous similar studies all over the world. The mean age of the participants was 37.5 years and 46.7% were female. Pearson's Chi-squared test was used for subgroup analyses. The majority of subjects cited brain disorders as a cause of epilepsy, while 17% indicated the will of God as the cause. Most individuals were willing to work with a person with epilepsy, allow their children to play with a child with epilepsy, and allow people with epilepsy to use public transportation (78-82%). However, only 28% were willing to accept the marriage of a family member to someone with epilepsy. The knowledge and attitudes towards epilepsy are similar to those in Europe, with the exception of a much lower acceptance regarding marriage to a person with epilepsy. However, the low acceptance for marrying someone with epilepsy reveals the remaining misconceptions about the nature of epilepsy in Iran, despite the high educational level in the studied population. Therefore, informational efforts must be employed to change the perception of epilepsy.

Work ability is an important issue from a social point of view, as it is essential for workers health and welfare. This study aimed to determine work ability among healthcare personnel and to investigate its relationship with demographic and lifestyle-related factors. Data were collected using the Work Ability Index (WAI) questionnaire among 517 personnel of a hospital in Tehran, Iran. Findings showed a mean WAI of 40.3 (±5.2) for the study population. Work ability was significantly lower in the older personnel and higher for men. A significant correlation was observed between BMI and exercise activity and WAI score. Moreover, employees with experience of less than five years had significant higher work ability than those with 16-20 years of service. Considering the young study population, it seems the mean WAI is not as desirable. The use of lifestyle promoting programs, besides workplace interventions, can be an effective strategy to increase work ability among healthcare workers.

Road traffic accidents are one of main problems in Iran. Multiple factors cause traffic accidents and the most important one is sleepiness. This factor, however, is given less attention in our country. Road traffic accidents relevant to sleepiness are studied. In this cross-sectional study, all road traffic accidents relevant to sleepiness, which were reported by police, were studied in Tehran province in 2009. The risk of road traffic accidents due to sleepiness was increased by more than sevenfold (odds ratio = 7.33) in low alertness hours (0:00-6:00) compared to other time of day. The risk of road traffic accidents due to sleepiness was decreased by 0.15-fold (odds ratio = 0.15) in hours with maximum of alertness (18:00-22:00) of circadian rhythm compared to other time of day. The occurrence of road traffic accidents due to sleepiness has significant statistical relations with driving during lowest point of alertness of circadian rhythm.

The natural radionuclide ((226)Ra, (232)Th and (40)K) contents were determined for 50 locations throughout the geological surface formations in a representative area in the city of Tehran, Iran, using high-resolution gamma-spectrometric analysis. The range of activity concentrations of (226)Ra, (232)Th and (40)K in the soil from the studied areas varies from 30.5±0.6 to 45.4±0.9, 27.3±0.5 to 57.1±1.1 and 328.0±4.6 to 768.5±13.4 Bq kg(-1) with overall mean values of 38.8±0.7, 43.4±0.8 and 555.1±8.9 Bq kg(-1), respectively. The mean radium equivalent activity, external hazard index, internal hazard index to quantify the internal exposure to radon and its daughter products, as well as the gamma activity concentration index for each sample are 143.6±4.6 Bq kg(-1), 0.39, 0.49 and 0.53, respectively. The average estimated radium equivalent is comparable with reported values for many countries in the world. Therefore, these areas may not pose radiological risks to the inhabitants due to harmful effects of the ionising radiation from the natural radioactivity in soil. The calculated average external and internal hazard indexes were found to be less than unity, as a recommended safe level. Estimates of the measured radionuclide content have been made for calculating the absorbed dose rate in the outdoor air at 1 m above the ground level. The absorbed dose rates resulting from those concentrations ranged from 48.1 to 88.7 nGy h(-1). Assuming a 20 % occupancy factor proposed by UNSCEAR, 2000, the corresponding effective dose rates in outdoor air equivalent to the population were calculated to be between 0.06 and 0.11 mSv y(-1). The measurement results and calculated values obtained from this study indicate that the dwelling areas in Tehran city, Iran, have background radioactivity levels within natural limits.

In this study, we aimed to assess comparative productivity of 21 pharmaceutical companies in Iran during 2000-2013. To evaluate the productivity trend of pharmaceutical companies in Iran, we used data envelopment analysis-based Malmquist index. "Total assets" and "capital stock" as inputs and "net sales" and "net profit" as outputs extracted from Tehran stock exchange, were selected to be included in the analysis. This method provides the possibility for analyzing the performance of each company in term of productivity changes over time. We also used an estimation generalized least square panel data model to identify the factors that might affect productivity of pharmaceutical companies in Iran using EViews 7 and Deep 2.1 software. The mean total productivity during all years of the study was 0.9829, which indicates the improvement in their overall productivity. The results, over the 13-year period, indicated that the range of productivity changes in pharmaceutical companies, that were included in this study, was between 0.884 and 1.098. Panel data model indicated that age of company could positively (t = 4.765978, P < 0.001) and being located in cities other than Tehran (the capital) could negatively (t = -5.369549, P < 0.001) affect the productivity of pharmaceutical companies. The analysis showed the new policy (brand-generic scheme) and also the type of ownership did not have a significant effect on the productivity of pharmaceutical companies. In this study, pharmaceutical productivity trends were fluctuated that could be due to the sub-optimal attention of policy makers and managers of pharmaceutical companies toward long-term strategic planning, focusing on productivity improvement.

The prevalence of obesity has been increasing in Iran over the past decade. This study aimed to determine the population-attributable fraction (PAF) of hypertension associated with obesity, abdominal obesity, and the joint effect of both in the central provinces of Iran. Prevalence of hypertension was extracted from the Iranian Ministry of Health Non-Communicable Disease Risk Factor InfoBase 2009. Measure of association between obesity and hypertension was extracted from Tehran Lipid and Glucose Study, for males and females, in order to calculate the PAF of hypertension associated with obesity. Age standardization of the reported prevalence of obesity was done using the World Health Organization method. The PAF of hypertension associated with the joint effect of obesity and abdominal obesity in females was highest in Semnan Province: 22.7 [95% confidence interval (CI): 4.2-35.6], followed by Qom 21.09 (95% CI: 3.7-33.1), and Yazd 20.3 (95% CI: 3.5-32.1). In males, the highest PAF was observed in Qom Province 31.07 (95% CI: 16.7-41.1), followed by Semnan 29.6 (95% CI: 15.9-39.3), Qazvin 25.9 (95% CI: 13.7-34.5), Tehran 24.2 (95% CI: 12.7-32.3), and Isfahan 20.4 (95% CI: 3.5-27.4). Prevalence of hypertension is higher in more developed provinces. PAFs suggest that a sizable share of hypertension in these provinces is associated with obesity. It is recommended that health promotion programs focus on obesity in the provinces with a higher share of hypertension due to obesity. Copyright © 2016 Ministry of Health, Saudi Arabia.

2015-01-01

Background: Fatherhood, similarly to motherhood, is an important role and responsibility. For accepting this role, one needs to be well-prepared. Awareness of father’s experiences of pregnancy can help us to develop plans for the promotion of the role of fatherhood. Objectives: The purpose of this study was to explore how first time fathers describe their experiences of pregnancy. Patients and Methods: The data in this qualitative study were collected by individual open-ended interviews in five public health prenatal care clinics in Tehran, Iran, during 2010 ‒ 2011. Participants were 26 Iranian and Moslem first-time fathers living in Tehran, whose partner was in the 32th to 40th week of her normal pregnancy. Qualitative content text analysis was used for analyzing interviews. Results: Through analysis of fathers’ experiences of their wives’ pregnancy, four categories, as well as associated subcategories, emerged. The categories include: “Emotional responses to pregnancy, Feeling of change, Accepting the reality and satisfaction, Developing identity as a father.” These categories describe the phenomenon of “Transition to fatherhood”. Conclusions: Transition to fatherhood extends beyond only moderate mental and social changes, and may be influenced by cultural background and beliefs. Therefore, caregivers should be aware of fathers' changes and needs during pregnancy, and support them while taking into consideration their culture and beliefs. PMID:25838928

Background: Primary health care physicians (PHCPs) are the first in the clinic to detect and help victims of intimate partner violence (IPV). Therefore, their attitude and practice toward domestic violence (DV) are important to manage this problem. The aim of current study was to compare the behavior and attitude of PHCPs about DV versus other health risk factors in Tehran, Iran. Methods: A convenience sample of 220 PHCPs was evaluated. The study was carried out in April 2012. Two self-administered questionnaires were used to identify physicians’ beliefs and behaviors on screening and intervention of DV and other health risk factors. All analyses were performed using SPSS version 18.0 (SPSS, Inc. Chicago, IL). Results: One hundred and ninety eight questionnaires were analyzed. PHCPs’ mean age was 39.06 (±7.5) years. Participants were just reported 10% screening of regular patients for DV compared with 29% to 48% for other health risk factors. Mean age of PHCPs was not associated with their approach toward the DV. Compared to male physicians, females spared more time for DV victims. Major of physicians (96%) believed that DV is not a private problem and is something that needs to be addressed cautiously. Conclusion: The results of this study indicated that DV screening occurs less than that of other health risk factors. Attitude of majority of PHCPs was positive for addressing this problem PMID:25695006

Objective Because of high psychological burden and considerable costs of in-vitro fertilization, it is greatly important to identify all factors that may influence its results. In this study, general anesthesia and spinal analgesia used for oocyte retrieval were compared in terms of success in treating infertility among couples who had undergone in-vitro fertilization at an infertility center in Tehran, Iran. Methods This cohort study that was based on analysis of patient records at Mirza Kochak Khan Hospital, Tehran University of Medical Sciences, in 2008-2009. In this study, the status of chemical pregnancy among those who experienced general anesthesia or spinal anesthesia for in-vitro fertilization for the first time were compared, and the possible effects of clinical and laboratory factors using logistic regression models were considered. Results Considering the number of transferred embryos, underlying cause of infertility and fetus grade, it was found that practicing spinal anesthesia is significantly related to increased chance of chemical pregnancy (adjusted Odds Ratio=2.07; 95% CI: 1.02,4.20; p=0.043). Conclusion According to analysis of recorded data in an infertility treatment center in Iran, it is recommended to use spinal anesthesia instead of general anesthesia for oocyte retrieval to achieve successful in-vitro fertilization outcome. This can be studied and investigated further via a proper multicentric study in the country. PMID:24715934

There are several studies regarding the predictors or risk factors of unintended pregnancy, but only a small number of studies have been carried out concerning the socio-economic factors influencing the unintended pregnancy rate. This study aimed to determine the socioeconomic inequality of unintended pregnancy in Tehran, Iran, as a developing country. In this hospital based cross-sectional study, 5152 deliveries from 103 hospitals in Tehran (the capital of Iran) were included in the analysis in July 2015. Socioeconomic status (SES) was measured through an asset-based method and principal component analysis was carried out to calculate the household SES. The concentration index and curve was used to measure SES inequality in unintended pregnancy, and then decomposed into its determinants. The data was analyzed by statistical Stata software. The Wagstaff normalized concentration index of unintended pregnancy (- 0.108 (95% Confidence Interval (CI) = - 0.119 ~ - 0.054)) endorses that unintended pregnancy is more concentrated among poorer mothers. The results showed that SES accounted for 27% of unintended pregnancy inequality, followed by the mother's nationality (19%), father's age (16%), mother's age (10%), father's education level (7%) and Body Mass Index (BMI) groups (5%). Unintended pregnancy is unequally distributed among Iranian women and is more concentrated among poor women. Economic status had the most positive contribution, explaining 27% of inequality in unintended pregnancy.

The limits of scientific planning: Doxiadis and the Tehran Action Plan.

PubMed

Madanipour, Ali

2010-01-01

Tehran after the Second World War experienced a modernization drive and rapid population growth. In 1972, the Greek planner, Constantinos Doxiadis, who had already undertaken major housing and planning projects in Iran, was invited to prepare an action plan for the city, to guide the future investment for easing the city's problems. Doxiadis saw cities as nightmares, but advocated that a holistic scientific analysis and a naturalist approach to urban growth management could address their problems. In applying his ideas to Tehran, however, the limits of his ideas of scientific planning became evident, not only through contextual pressures, such as lack of time and data, but also through the planning consultant's approach, in which commercial considerations and the application of readymade solutions could shape the outcome. Rather than working with the context, Doxiadis followed the modernist tenet of breaking with the past, proposing the creation of West Tehran, an alternative to the city where all future growth should take place on a utopian basis. The radical nature of his proposals, his death, and a turbulent revolution aborted the impact of his action plan on Tehran, while faith in modernist scientific planning was widely being abandoned.

Background: Rodents are an important source of zoonotic diseases for human. The aim of this study was to determine the infectivity of rodents with intestinal helminths in North Khorasan Province, Iran. Methods: One hundred and thirteen rodents were collected using different collection methods such as kill and live traps, digging of their burrow, filling of their hiding places with water and hand net during 2011–2013. Their alimentary canals were removed in the laboratory and helminths were determined in the department of parasitology, Tehran University of Medical Sciences. Results: Thirteen species of helminths parasites were found in 13 species of rodents, including Aspiculuris tetraptera, Hymenolepis diminuta, Nippostrongylus brasiliensis, Protospirura Seurat, Rictolaria ratti, Skrjabinitaenia lobata, Streptopharagus kuntzi, Syphacia obvelata, Taenia taeniaeformis, Trichuris muris, Cysticercus fasciolaris, Acanthocephal. spp and Trichuris spp. Some of them were reported for the first time in new host in Iran. S. obvelata and A. tetraptera were the most frequent parasites and P. Seurat, R. ratti and C. fasciolaris were found only in one rodent. Conclusion: This is the first study to investigate the intestinal parasites in rodents in this area. Among different species identified, some of helminths were reported in new host. PMID:28761488

Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehran University, Iran. A total of 55 DNA samples were extracted from birds from nine different species of the order psittaciformes. A robust conventional polymerase chain reaction (PCR) was applied to detect the rep gene of the virus. Ten out of 55 samples, from four different species, were tested positive for BFDVs in PCR (Melopsittacus undulates (4), Psittacula Krameri (3), Psittacus erithacus (2), Platycercus eximius (1)). Molecular identification of the detected BFDVs was performed based on their rep gene sequences. The phylogenetic analysis revealed that the Iranian BFDVs from this study were clustered into four genetically distinct clades belonging to different genetic subtypes of BFDVs (L1, N1, T1, and I4). Although the relation between the samples and their related subtypes in the tree are discussed, further studies are needed to elucidate the host specificity and incidence of the BFDVs from different genetic subtypes.

Background: Our aim in this survey was to explore descriptive epidemiology of injuries in Tehran in 2012 and to report the recalled estimates of injury incidence rates. Methods: A population survey was conducted in Tehran during 2012, within which a total of 8626 participants were enrolled. The cluster sampling was used to draw samples in 100 clusters with a pre-specified cluster size of 25 households per cluster. Data were collected on demographic features, accident and injury characteristics based on the International Classification of Diseases (ICD10). Results: A total of 618 injuries per 3 months were reported, within which 597 cases (96.6%)were unintentional injuries. More than 82% of all injuries were those caused by exposure to inanimate mechanical forces, traffic accidents, falls and burns. Above 80% of the traffic injuries happened among men (P<0.001). About 43% of the unintentional injuries were mild injuries.After the age of 40, women, unlike men, had higher risks for being injured. The estimated annual incidence rate for all types of injuries was 284.8 per 1000 (95% CI: 275.4-294.4) and for unintentional injuries was 275.2 per 1000. Conclusion: Injuries are major health problems in Tehran with a highly reported incidence. The status is not substantially improved over the recent years which urges the need to be adequately and emergently addressed. As the incidence rate was estimated based on participant recalls, the real incidence rate may even be higher than those reported in the current study.

Adolescent health concerns are an important source of information that should be considered when planning school and community health promotion policies, programs and services. Adolescence is a critical period of human development and the health concerns of adolescents can point to important issues that may be eclipsed by epidemiologic and other clinical sources of information. This study aimed to assess the health concerns of adolescents living in Tehran, Iran and to examine associations between selected demographics and the health concerns reported by participants. This study was a population-based cross-sectional survey in 2011. Data were collected from a stratified random cluster sample of 915 adolescents, aged 14-18 years, living in Tehran, using the Persian version of the Adolescent Health Concern Inventory (AHCI-P). The data were analyzed using the χ2, Mann-Whitney and Kruskal-Wallis tests and logistic regression analysis. The mean numbers of health concerns in girls and boys were 48 (±27.6) and 44.5 (±27.4) respectively. The highest ranking health concern subscale for both girls and boys was The Future, and "being successful" was endorsed as the most prominent concern in the subscale. Female (OR: 1.42, CI 95%: 1.08-1.87), mother's educational level (OR: 2.23, CI 95%: 1.07-4.65) and living in northern (OR: 1.76, CI 95%: 1.13-2.74) and western (OR: 2.02, CI 95%: 1.30-3.16) regions of Tehran were significant predictors of a higher level of health concerns. Findings can be used to inform school and public health promotion policies, programs and supportive services designed to improve the overall health and well-being of adolescents.

To assess oral health literacy level and oral health information of Iranian adults in Tehran, and to determine the factors related to oral health literacy. A cross-sectional population study. A random sample of 1,031 adults in Tehran, Iran. Oral health literacy was measured using an oral health adult literacy questionnaire (OHL-AQ). Variation in use of information sources by socio-economic and demographic background was estimated by odds ratios. A multiple linear regression model served to determine predictor factors of OHL-AQ scores controlling for characteristics of the subjects and number of information sources. The mean OHL-AQ score was 10.5 (sd 3.0). Women (p < 0.001), younger (p < 0.001), and better educated participants (p < 0.001) had higher OHL-AQ scores. The most common sources of oral health information were dentists (52.6%), and TV/Radio (49.5%). According to the regression model, females (p = 0.001), high educational level (p < 0.001), and use of multiple information sources (two sources p = 0.01, three sources or more p = 0.002) were the main predictor factors of OHL-AQ scores. The average oral health literacy level of Iranian adults was low. Disseminating evidence-based oral health care information from multiple sources including TV/radio, dentists, and other health professionals in different settings should improve public oral health literacy.

Due to the tropism of human parvovirus B19 to erythroid progenitor cells, infection in patients with an underlying hemolytic disorder such as beta-thalassemia major leads to suppression of erythrocyte formation, referred to as transient aplasia crisis (TAC), which may be life-threatening. We investigated the prevalence of parvovirus B19 among patients with beta thalassemia major attending the Zafar Adult Thalassemia Clinic in Tehran, Iran. This cross-sectional study was performed to determine the presence of parvovirus B19 DNA in blood samples and parvovirus B19 genotypes in plasma samples of patients with thalassemia major. The population consisted of 150 patients with beta-thalassemia major who attended the Zafar clinic in Tehran. Specimens were studied using a real-time polymerase chain reaction assay. The prevalence of parvovirus B19 in our study population was 4%. Of 150 patients with thalassemia, six (4%) were positive for B19 DNA. There was no significant correlation between blood transfusion frequency and B19 DNA positivity. Finally, phylogenetic analysis of human parvovirus B19 revealed genotype I in these six patients. In this study, acute B19 infections were detected in patients with beta thalassemia major. Screening of such high-risk groups can considerably reduce the incidence and prevalence of B19 infection; thus, screening is required for epidemiologic surveillance and disease-prevention measures.

Smoking and unhealthy diet are two major risk factors for non-communicable diseases. The aim of this study was to investigate the possible association between these two risk factors amongst healthy adults 30-60 years old in Tehran, Iran. Overall, 2602 healthy adults 30 to 60 years old in Tehran were studied. The demographic characteristics, anthropometric and smoking status of the participants were questioned. The frequency of consumption of red meat, white meat, fruits and vegetables, dairy products, bread and cereals and fast food were questioned to be daily, weekly, monthly, once every 6 months or yearly and categorized as "healthy" or "unhealthy". Of the 2602 participants, 974 (37.4%) had smoked more than 100 cigarettes in their life time and continued daily or smoked occasionally. Smokers significantly consumed more fast food and white meat but less fruit and vegetables and dairy product (P<0.0001). Totally, 586 (22.5%) consumed "unhealthy" diet. A positive association between cigarette smoking and unhealthy diet (OR=1.68; 95% CI: 1.40-2.03) were found. After adjusting the analysis for the effect of age, education and gender, the odds ratio of consuming unhealthy diet for the smoker increased to 1.83 (1.50, 2.25) compared with non-smoker. Our study found a noticeable association between cigarette smoking and unhealthy diet. Smoking cessation and changing diet program for smokers is recommended.

Daily newspapers are the main platform by which substance misuse treatment (SMT) centers in Iran advertise their services. However, these advertisements provide little information on treatment options or costs. The current research aimed to use advertisements to compile a schema of treatment services and to map the extent and nature of drug treatments offered. During a four-week period (April to May) in 2009, the four most popular Persian newspapers printed in Tehran were reviewed. Across these publications 1704 advertisements were posted by 66 SMT centers. Each center was then contacted by telephone to complete a structured interview about services offered and related costs. The advertisements were also decoded through a quantitative contextual analysis method. On average, each SMT center published 26 advertisements during the review period, costing 421 US$. In addition, advertisements included word signifiers in six main categories including centers' introduction (100%), treatment types (91%), treatment duration (68%), medicines (70%), treatment features (60%) and psychological facilities (52%). The three detoxification programs advertised were the rapid method (57% of clinics, 443.23 US$), buprenorphine (68%, 265 US$) and methadone (71%, 137 US$). More than 90% of the centers in Tehran were offering methadone maintenance (99 US$, per month). SMT services in the Iranian market ranged from abstinence to maintenance programs, with opiates as the main focus. This review of centers' advertisements provides an indirect but rapidly obtained picture of the drug misuse treatment network. Copyright © 2014 Elsevier B.V. All rights reserved.

Background Breast cancer is the 5th leading cause of cancer death in Iranian women. This study analyzed 3010 women with breast cancer that had been referred to a cancer research center in Tehran between 1998 and 2014. Methods In this retrospective study, we analyzed 3010 breast cancer cases with 32 clinical and paraclinical attributes. We checked the data quality rigorously and removed any invalid values or records. The method was data mining (problem definition, data preparation, data exploration, modeling, evaluation, and deployment). However, only the descriptive analyses' results of the variables are presented in this article. To our knowledge, this is the most comprehensive study on breast cancer status in Iran. Results A typical Iranian breast cancer patient has been a 40–50-year-old married woman with two children, who has a high school diploma and no history of abortion, smoking, or diabetes. Most patients were estrogen and progesterone receptor positive, human epidermal growth factor (HER) negative, and P53 negative. Most cases were detected in stage 2 with intermediate grade. Conclusion This study revealed original findings which can be used in national policymaking to find the best early detection method and improve the care quality and breast cancer prevention in Iran.

To explore the contextual influences on childhood obesity in Tehran, Iran to inform future development of an obesity prevention intervention for Iranian primary school children. Qualitative study. Focus groups and interviews with parents and school staff were convened to explore their perceptions of the causes of childhood obesity. Eleven focus groups and three interviews were held with parents and school staff (88 participants in total) from three different socio-economic areas in Iran's capital city, Tehran. All the discussions were transcribed verbatim in Persian. An iterative thematic approach was used for data analysis. Overall, the causes of childhood obesity were perceived to relate to macro-level policy influences, the school environment, sociocultural factors, and family and individual behavioural factors, acting in combination. A key emergent theme was the pervasive influence of Government policies on children's food intake and physical activity. Another key theme was the political and sociocultural context that does not support girls and women in Iran in having active lifestyles. The findings suggest that parents and school staff have sophisticated views on the possible causes of childhood overweight and obesity which encompassed behavioural, structural and social causes. A prominent emerging theme was the need for state level intervention and support for a healthy environment. Any local initiatives in Iran are unlikely to be successful without such support. Childhood obesity is growing in Iran and it is seen as one of the features of the nutrition transition in developing countries. Findings from cross-sectional studies suggest a range of lifestyle factors contribute to obesity in the Iranian population. This qualitative study explores the socioenvironmental changes contributing to childhood obesity in primary school-aged children in Iran. Findings have provided important contextual data on the perceived contributors to childhood obesity in Iran, such as macro-level policy influences on accessibility to healthy food and physical activity, competing priorities at school level, sociocultural influences on diet and physical activity and limited knowledge and skills of parents. This has laid the foundation for the development of appropriate childhood obesity prevention interventions. Copyright © 2013 The Royal Society for Public Health. Published by Elsevier Ltd.

Study and comparison of the maximum stress directions and main fault orientations in some active zones in Iran Khatereh Forouhid, Manouchehr Ghorashi, Atefeh Faraji Institute of Geophysics, Tehran University, Tehran, Iran kforouhid@yahoo.com Farajiatefeh@yahoo.com The Iranian plateau is the widest active zone in Alpine-Himalayan collision system that is located between two stable platforms, the Arabia in southwest and Eurasia in northeast. The convergence of these two platforms towards each other is the main reason for seismicity and different styles of deformation observed in Iran. In this study, the Iranian plateau is divided into 7 regions based on their seismotectonic characteristics. These regions are; Zagros, Makran, East Iran, Alborz, Kopeh Dagh, Central Iran and Azarbayejan (northwest of Iran). In each region, focal mechanism solutions of early and modern instrumental earthquakes (the only source of information suitable to use for stress distribution study in Iran) with magnitudes more than 5.0 and their relations to active faults are considered. By studying each maximum stress direction based on a group of earthquake focal mechanisms and considering main fault orientations, each region is studied individually. According to these data, some of these regions are divided into smaller parts. These sub-divided parts have some characters that make them different from their neighbors in the same region. In this regard, Zagros is studied in detail based on seismotectonic characteristics and divided into three parts, with N-S maximum stress direction (compressional) in one part and two different kind of NE-SW direction in two other. We use this information to investigate the style and distribution of active faulting in the Zagros and the relationships of this activity with shortening of the Arabia-Eurasia collision. It is worth to mention that as the fault slip will almost occur in the direction of maximum resolved shear stress on the fault plane, probably strain is almost estimated according to these stress directions and this issue can be considered in further studies in this region.

This study is a sociological analysis of the three dimensions of social structure including institutional, relational, and embodied structures that have an impact on the individuals' deviant behaviors in the society. The authors used a mix method to analyze the qualitative and quantitative data of 402 high risk abandoned substance users in 2008 in Tehran, capital city of Iran. The leading reasons of substance use were categorized into four fundamental themes as follows: stress, deviant social networks, and low social capital and weak social support sources. In addition, the epidemiology model of regression analysis provides a brief explanation to assess the association between the demographical and etiological variables, and the drug users' deviant behaviors. In sum, substance use is discussed as a deviant behavior pattern which stems from a comorbidity of weak social structures.

Background: Among the proposals for joint disease mapping, the shared component model has become more popular. Another advance to strengthen inference of disease data is the extension of purely spatial models to include time aspect. We aim to combine the idea of multivariate shared components with spatio-temporal modelling in a joint disease mapping model and apply it for incidence rates of seven prevalent cancers in Iran which together account for approximately 50% of all cancers. Methods: In the proposed model, each component is shared by different subsets of diseases, spatial and temporal trends are considered for each component, and the relative weight of these trends for each component for each relevant disease can be estimated. Results: For esophagus and stomach cancers the Northern provinces was the area of high risk. For colorectal cancer Gilan, Semnan, Fars, Isfahan, Yazd and East-Azerbaijan were the highest risk provinces. For bladder and lung cancer, the northwest were the highest risk area. For prostate and breast cancers, Isfahan, Yazd, Fars, Tehran, Semnan, Mazandaran and Khorasane-Razavi were the highest risk part. The smoking component, shared by esophagus, stomach, bladder and lung, had more effect in Gilan, Mazandaran, Chaharmahal and Bakhtiari, Kohgilouyeh and Boyerahmad, Ardebil and Tehran provinces, in turn. For overweight and obesity component, shared by esophagus, colorectal, prostate and breast cancers the largest effect was found for Tehran, Khorasane-Razavi, Semnan, Yazd, Isfahan, Fars, Mazandaran and Gilan, in turn. For low physical activity component, shared by colorectal and breast cancers North-Khorasan, Ardebil, Golestan, Ilam, Khorasane-Razavi and South-Khorasan had the largest effects, in turn. The smoking component is significantly more important for stomach than for esophagus, bladder and lung. The overweight and obesity had significantly more effect for colorectal than of esophagus cancer. Conclusions: The presented model is a valuable model to model geographical and temporal variation among diseases and has some interesting potential features and benefits over other joint models.

Leishmaniasis covers a range of clinical manifestations. Estimation of the burden of leishmaniasis may help guide healthcare management personnel and policy-makers in applying effective interventions. The present study aimed to calculate the incidence and burden of cutaneous and visceral leishmaniasis in Iran in 2013. To evaluate the epidemiological aspects of the disease in Iran, published studies over the past 20 years were searched and the viewpoints of relevant specialists in Iran were obtained. Data were collected from the Ministry of Health and from the Tehran University of Medical Sciences. To calculate years of life lost due to premature death, standard expected years of life lost was used. Standard life table of Global Burden of Disease (GBD) 2010 with the life expectancy of 86.02 years for both sexes was used to calculate the remaining potential years of life at any age from death. The overall incidence of cutaneous and visceral leishmaniasis was calculated as 22 and 0.092 per 100000 population of Iran, respectively. The burden of leishmaniasis was 99.5 years: 95.34 and 4.16 years for cutaneous and visceral, respectively. Sensitivity was analyzed and deaths predicted by the Institute of Health Metrics and Evaluation added, the burden of visceral leishmaniasis was 726 years. The share of leishmaniasis burden in Iran is lower than the global burden of the disease. GBD 2010 standard method is recommended to calculate the burden of leishmaniasis in different countries and set local priorities on the basis of these measures.

Background: Poliomyelitis is still an endemic disease in many areas of the world including Africa and South Asia. Iran is polio free since 2001. However, due to endemicity of polio in neighboring countries of Iran, the risk of polio importation and re-emergence of wild polio virus is high. Case definition through surveillance system is a well-defined method for maintenance of polio eradication in polio free countries. Methods: In a cross-sectional survey from 2007 to 2013, we reviewed all the records of under 15 years old patients reported to Acute Flaccid Paralysis Committee (AFPC) in Isfahan province, Iran. All cases were visited by members of the AFPC. Three stool samples were collected from each reported case within 2 weeks of onset of paralysis and sent to National Polio Laboratory in Tehran, Iran, for poliovirus isolation. Data were analyzed by SSPS software (version 22). Student's t-test and Chi-square was used to compare variables. Statistical significance level was set at P < 0.05. Results: In this 6-year period 85 cases were analyzed, 54 patients were male (63.5%) and 31 were female (36.5%). The mean age of patients was 5.7 ± 3.9 years. The most common cause of paralysis among these patients was Guillian–Barré syndrome (83.5%). We did not found any poliomyelitis caused by wild polio virus. Only one case of vaccine associated poliomyelitis was reported. Conclusion: Since 1992, Iran has a routine and high percent coverage of polio vaccination program for infants (>94%), with six doses of oral polio vaccine (OPV). Accurate surveillance for poliomyelitis is essential for continuing eradication. PMID:26015925

Cystic echinococcosis (CE), caused by the larval stage of Echinococcus granulosus, presents an important medical and veterinary problem globally, including that in Iran. Different genotypes of E. granulosus have been reported from human isolates worldwide. This study identifies the genotype of the parasite responsible for human hydatidosis in three provinces of Iran using formalin-fixed paraffin-embedded tissue samples. In this study, 200 formalin-fixed paraffin-embedded tissue samples from human CE cases were collected from Alborz, Tehran, and Kerman provinces. Polymerase chain reaction amplification and sequencing of the partial mitochondrial cytochrome c oxidase subunit 1 gene were performed for genetic characterization of the samples. Phylogenetic analysis of the isolates from this study and reference sequences of different genotypes was done using a maximum likelihood method. In total, 54.4%, 0.8%, 1%, and 40.8% of the samples were identified as the G1, G2, G3, and G6 genotypes, respectively. The findings of the current study confirm the G1 genotype (sheep strain) to be the most prevalent genotype involved in human CE cases in Iran and indicates the high prevalence of the G6 genotype with a high infectivity for humans. Furthermore, this study illustrates the first documented human CE case in Iran infected with the G2 genotype. PMID:25535316

Although the number of lung transplants is limited because of general shortage of organ donors, ex vivo lung perfusion is a novel method with 2 main benefits, including better evaluation of lung potential and recovery of injured lungs. The main aim of this study was to establish and operationalize ex vivo lung perfusion as the first experience in Iran. This was a prospective operational research study on 5 cases, including 1 pig from Vienna Medical University and 4 patients from Masih Daneshvari Hospital. All organ donations from brain dead donors were evaluated according to lung transplant or ex vivo lung perfusion criteria from May 2013 to July 2015 in Tehran, Iran. If a donor did not have any sign of severe chest trauma or pneumonia but had poor oxygenation due to possible atelectasis or neurogenic pulmonary edema, their lungs were included for ex vivo lung perfusion. A successful trend in the difference between the pulmonary arterial Po2 and the left atrial Po2 was observed, as well as an increasing pattern in other functional parameters, including dynamic lung compliance and a decreasing trend in pulmonary vascular resistance. These initial trials indicate that ex vivo lung perfusion can lead to remarkable progress in lung transplant in Iran. They also provide several important pieces of guidance for successful ex vivo lung perfusion, including the necessity of following standard lung retrieval procedures and monitoring temperature and pressure precisely. The development of novel methods can provide opportunities for further research studies on lungs of deceased donors and lead to undiscovered findings. By keeping this science up to date in Iran and developing such new and creative methods, we can reveal effective strategies to promote the quality of donor lungs to support patients on transplant wait lists.

In spite of decreasing incidence of orthopedic device-related infections to 1%, nowadays, device-related infection still remains a diagnostic, therapeutic and cost-related problem. The objective of this study is to evaluate the contributing risk factors for orthopedic device-related infections in Sina Hospital, Tehran, Iran. Three hundred and thirty patients who underwent orthopedic device implantation from 2002-2006 were enrolled; among them, 110 patients were complicated with infection. Descriptive and logistic regression analyses were performed to determine the risk factors for device related infections. Patients with infection were older compared to those without infection. The Staphylococcus aureus was the commonest organism. A correlation was observed between wound infection and external fixation, an underlying health condition, and addiction which were independent risk factors for a device related infection. Orthopedic device-related infection puts a great financial burden on patients and hospital resources and could lead to morbidity and mortality in patients. So, appropriate pre and postoperative wound care for dirty wounds, especially when external fixators are used, and in patients with poor conditions or addiction should be done with more caution.

Pemphigus is a rare and chronic life-threatening disease. The clinical picture varies in reports from different regions of the world. To define the clinical forms of pemphigus in a large cohort of patients. Prospective analysis of 1209 patients diagnosed and followed at the Pemphigus Research Unit, Tehran University for Medical Sciences, from 1984 to 2003. The mean age at onset was 42 years with a female to male ratio of 1.5/1. The most frequent form was pemphigus vulgaris. In pemphigus vulgaris, patients' mucous membrane involvement alone was observed in 18%, skin involvement alone in 12%, and both in 70%. Pemphigus foliaceus was observed in 7% of the patients. Most complications were iatrogenic. In Iran, pemphigus vulgaris is the most frequent form of pemphigus. Females are more prone to the disease. The incidence of pemphigus in Tehran is approximately 1.6 per 100,000/year, and in Iran 1.0 per 100,000/year. The age of onset was lower than classically reported. Death occurred in 6.2% of the patients. In pemphigus vulgaris, the mucosal and skin form together had a worse prognosis than the other clinical forms.

Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders among infertile patients. This study aimed to determine the prevalence of GAD and its associated factors among infertile patients in Tehran, Iran. This cross-sectional study included 1146 infertile patients in a referral fertility center in Tehran, Iran between May and October 2017. GAD was measured using the Generalized Anxiety Disorder-7 (GAD-7) scale. The associations between GAD and demographic/fertility characteristics were estimated using simple and multiple logistic regression with odds ratio (OR) and 95% confidence interval (CI). The mean total GAD-7 score was 6.61 (SD = 5.32). Using a cut-off value of 10, the prevalence of GAD was 28.3%. In adjusted analysis, female sex (OR = 2.54, 95% CI = 1.88-3.42, P < 0.001), low educational level (OR = 1.45, 95% CI = 1.08-1.94, P = 0.012), high infertility duration (OR = 1.05, 95% CI = 1.01-1.09, P = 0.013), and treatment failure (OR = 1.52, 95% CI = 1.13-2.04, P = 0.006) were associated with GAD. The prevalence of GAD is relatively high in infertile patients. We conclude that all infertile patients should be screened for symptoms of GAD and treated for this disorder as need arises.

This study analyzed characteristics of oral cancer patients from Tehran, Iran, and their tumors. Data came from the patient records of 30 major hospitals in Tehran. Patients (n = 1042), diagnosed with invasive oral cancer in 1993-2003, were classified by primary tumor site according to ICD-10 (C00-C10). Data were analyzed separately for lip, oral cavity and salivary gland tumors. Statistical evaluation included chi and t-test. Of all cases, 59% were male. Age for all cases ranged from 6-103 years, mean age was 58.8 years (SD 16; median 62); 89% were older than 40. Tumor site breakdown was 65% oral cavity, 21% major salivary glands and 14% lip. A clear gender difference (P < 0.001) appeared regarding the primary tumor sites: women dominated in oral cavity cancers and men in lip cancers. The most common cancer site was the tongue (32%), accounting for 50% of the oral cavity cancers. Histologically, 88% of all oral cavity and lip cancers were squamous cell carcinomas, 10% of those were in age /= age 65. At the time of diagnosis, 59% of oral cavity cancers and 29% of lip cancers were at stage III or IV (P < 0.001). The results emphasize an urgent need for a national program focusing on early detection of oral cancers, including educational information addressed to oral health professionals.

There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal.

Polychlorinated biphenyl (PCB) contamination of oils from all transformers of the national electrical grid in Tehran, Qom, and Alborz, three central provinces of Iran, was assessed. The concentration of PCBs in transformer oils was determined by gas chromatography. At the national level, the proportions of transformers with oil PCB contents of <5, 5-49, 50-499, 500-4999, and >5000 ppm were determined to be 85.7, 12.4, 1.6, 0.1, and 0.1%, respectively. About 0.5% of transformer oils (66,000 kg out of 13,342,000 kg) exhibited PCB levels higher than 50 ppm that based on the Stockholm Convention should be phased out before 2025. The contaminated oils contained 91.4% of detected PCBs (132 kg PCBs out of 144 kg PCBs) and were located in 1.9% of transformers (27 transformers out of 1449 transformers). Statistical analysis indicated that the year of manufacture and manufacturing company provided significant effects on PCB contamination (p value <0.001). PCB contamination of transformer oils in Tehran was higher than that of the other provinces that could be mainly caused by the older average year of manufacture. PCB levels higher than 499 ppm were also observed only in Tehran. This study provided valuable information for future studies on identification of PCB-contaminated transformers as well as planning and design of waste management facilities for PCB-contaminated oils at the national level.

Molecular identification of Candida species isolated from gastro-oesophageal candidiasis in Tehran, Iran

PubMed Central

Mohammadi, Rasoul; Abdi, Saeed

2015-01-01

Aim: The aim of this investigation is identification of Candida strains isolated from patients with gastro-oesophageal candidiasis in Tehran, Iran. Background: Gastro-oesophageal candidiasis is a rare infection and appears mainly in debilitated or immunocompromised patients. Colonization by Candida spp. may occur in this region and the organism can remain for several months or years in the absence of inflammation. The main infection symptom is the presence of white plaques in gastro-oesophageal surface. C. albicans remains the most prevalent Candida spp. identified in gastrointestinal candidiasis. Regarding differences in susceptibilities to antifungal drugs among Candida spp., identification of isolates to the species level is significant to quick and appropriate therapy. Patients and methods: A total of 398 patients underwent gastrointestinal endoscopy during February 2012 to October 2014 were included in the present study. Histological sections from all endoscopic gastric and oesophageal biopsies were prepared, stained with Periodic acid–Schiff (PAS), and examined for the presence of fungal elements. Part of the biopsy sample was sub-cultured on sabouraud glucose agar. The genomic DNA of each strain was extracted using FTA® Elute MicroCards. Molecular identification of Candida isolates was performed by PCR-RFLP technique with the restriction enzyme HpaII. Results: Twenty-one out of 398 cases (5.2%) were found to have gastro-oesophageal candidiasis. Candida albicans was the main strain isolated from clinical samples (90.5%), followed by C. glabrata (4.7%), and C. parapsilosis (4.7%). Conclusion: Due to varying antifungal susceptibility of Candida spp. careful species designation for clinical isolates of Candida was recommended by a rapid and meticulous method like PCR-RFLP.

Background Homeless people are at risk of contracting communicable infectious diseases, as they indulge in risky behaviours and lifestyle. This study was conducted to determine the prevalence of the aforementioned infections and related risk behaviours among homeless people in Tehran. Methods In this study a convenience sample of 593 homeless individuals was studied. The ELISA method was used for the detection of HIV, HCV and HBV. Clinical symptoms, sputum cultures, acid fast bacilli smears, and chest X-rays were used to identify active pulmonary tuberculosis, and the Interferon Gamma Release Assay (IGRA) test was used to identify latent tuberculosis. Results The prevalence of HIV, HBV, HCV and latent tuberculosis was 3.4%, 2.6%, 23.3% and 46.7%, respectively. Active pulmonary tuberculosis was found in 7 persons (1.2%). Injection drug use was an independent risk factor for HIV, HCV and HBV infections. Older people had a higher proportion of Mycobacterium tuberculosis infection (OR: 2.6, 95%CI: 1.9, 3.7) and HCV positivity (OR: 1.7, 95% CI: 1.1, 2.5). Conclusion Our findings highlighted that much more attention needs to be paid to the health of homeless people. PMID:24896247

In this paper, we present the major curricular reform in MD program of Tehran University of Medical Sciences, the oldest and the largest medical university in Iran, initiated about a decade ago. Following a comprehensive program evaluation, many of the basic challenges of the traditional curriculum were revealed, namely, lack of pre-defined competencies for graduates, over-reliance on teacher-centered teaching methods, over-emphasis on knowledge base in student assessments, and focusing solely on biomedical aspects of patient care. In 2010, a vision statement for reform was created and approved by the University Council. The new curriculum was launched in 2011. The changes included: revising the content of the courses, assimilating horizontal and vertical integration, emphasizing clinical skills, encouraging active involvement in patient management, providing more opportunity for supervised practice, integrating behavioral and psychosocial topics into the curriculum, incorporating interactive teaching methods, assessing students' higher levels of cognition, and strengthening workplace assessments. To evaluate the changes, data were continuously collected and analyzed from the beginning. Changing the curriculum of an MD program is a laborious task which should be planned and undertaken carefully and cautiously. It is an endless, yet invaluable and satisfying endeavor toward better future.

Poisoning is a frequent cause of referral to medical emergencies and a major health problem around the world, especially in developing countries. We aimed to review the epidemiology and pattern of adult poisoning in Iran in order to facilitate the early diagnosis and management of poisoning. The pattern of poisoning is different in various parts of Iran. Pharmaceutical compounds were the most common cause of poisoning in most parts of Iran. Pesticide-related toxicities were more common in northern agricultural regions, whereas bites and stings were seen more commonly in southern Iran. Carbon monoxide poisoning was common in cities with many motor vehicles such as Tehran and in colder climates such as in northern and western regions due to inadequately vented gas appliances such as stoves and heaters. Majoon Birjandi (containing cannabis) is a unique substance used in eastern Iran. Poisoning by opioids, tramadol, and pesticides (organophosphate and aluminum phosphide) has remained a common hazard in Iran. Poisoning-associated morbidity and mortality rates vary by region and have changed over time due to the introduction of new drugs and chemicals. Early diagnosis and proper treatment may be lifesaving; thus, understanding the general pattern of poisoning in different regions is important. PMID:28761199

Poliomyelitis is still an endemic disease in many areas of the world including Africa and South Asia. Iran is polio free since 2001. However, due to endemicity of polio in neighboring countries of Iran, the risk of polio importation and re-emergence of wild polio virus is high. Case definition through surveillance system is a well-defined method for maintenance of polio eradication in polio free countries. In a cross-sectional survey from 2007 to 2013, we reviewed all the records of under 15 years old patients reported to Acute Flaccid Paralysis Committee (AFPC) in Isfahan province, Iran. All cases were visited by members of the AFPC. Three stool samples were collected from each reported case within 2 weeks of onset of paralysis and sent to National Polio Laboratory in Tehran, Iran, for poliovirus isolation. Data were analyzed by SSPS software (version 22). Student's t-test and Chi-square was used to compare variables. Statistical significance level was set at P < 0.05. In this 6-year period 85 cases were analyzed, 54 patients were male (63.5%) and 31 were female (36.5%). The mean age of patients was 5.7 ± 3.9 years. The most common cause of paralysis among these patients was Guillian-Barré syndrome (83.5%). We did not found any poliomyelitis caused by wild polio virus. Only one case of vaccine associated poliomyelitis was reported. Since 1992, Iran has a routine and high percent coverage of polio vaccination program for infants (>94%), with six doses of oral polio vaccine (OPV). Accurate surveillance for poliomyelitis is essential for continuing eradication.

Evaluating the relation between Iranian drivers' knowledge, attitude, and practice (KAP) regarding traffic regulations, and their deterministic effect on road traffic crashes (RTCs). Two cities of Tehran and Zahedan, Iran. A cross-sectional study was designed. Using a simplified cluster sampling design, 2200 motor vehicle drivers including 1200 in Tehran and 1000 in Zahedan were selected. Sixty locations in Tehran and 50 in Zahedan were chosen. In each pre-identified location, 20 adult drivers were approached consecutively. A questionnaire developed by researchers was filled by each participant. The questionnaire had four sections including items assessing the demographics, knowledge, attitude and practice of drivers toward traffic regulations. Logistic regression analysis was used to evaluate the relationship between the RTCs and KAP variables. The study sample consisted of 619 (28.1%) occupational and 1580 (71.8%) private drivers. Among them, 86.4% were male. The median age was 33.6 ± 10.83. Drivers in Tehran and Zahedan had no significant differences between their mean scores of KAP items of the questionnaire. Higher knowledge, safer attitude, and safer practice were associated with a decreased number of RTC. After adjusting for possible confounders, increase of one standard deviation in attitude and practice scores (but not knowledge) resulted in 26.4% and 18.5% decrease in RTC, respectively. Finally, considering knowledge, attitude and practice of drivers in one model to assess their mutual effect, it was shown that only attitude is significantly associated with a decrease of RTC (OR=0.76, P=0.007). Increase in attitude and practice accompanied with decreased number of RTCs in Iranian drivers. Specifically, drivers' attitude had the crucial effect. It is not knowledge and standard traffic education; rather it is how such education is registered as an attitude that translates what is being learned into actions. Without safer attitude, even safer self-reported practice will not result in lower RTCs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Injection drug use is one of the major public health problems in Iran. Injection drug use is associated with numerous negative health outcomes, such as blood-borne infections (HIV, HCV) and injection site skin infections (abscesses, cellulitis). The aim of this study was to determine prevalence of injection site skin infections and its associated risk factors among people who inject drugs (PWID) in Tehran, Iran. The cross-sectional study was conducted from March to August 2016 in Tehran province. A total of 500 PWID were recruited by convenience and snowball sampling from Drop-in Centers (DIC) in the South of Tehran. Our primary outcomes were self-report of ever having injection sites skin infections and receiving treatment for them. We first examined associations between individual variables and lifetime history of having injection site infections in bivariate analysis using the chi-square or Fisher's exact tests, as appropriate. Variables with P-value <.2 were included in a multiple logistic regression model. Overall, 40% (CI95%: 30.3%, 52.2%) of participants reported ever having an injection site infection. In the multivariable model, those with low socioeconomic status (AOR = 2.4, P = .03), self-reported as HIV positive (AOR =1.6, P = .01), reporting more than 3 injections per day (AOR = 4.1, P = .03) and reuse of their own syringes (AOR = 8.5, P = .03) were more likely to have injection sites skin infections. PWID who used needle and syringe program (NSP) services were less likely to report injection site infections (AOR = 0.5, P = .04). We have identified several risk factors for injection sites infections among PWID, including frequency of injection per day, reuse of their own syringes, not using NSP services, HIV status, socioeconomic status with skin infections in PWID. Prevention strategies to reduce skin infections should focus on high-risk injection behaviors and improving access to NSP services. © 2018 Wiley Periodicals, Inc.

Iran is one of 27 countries that are likely to face increasing water shortage crises between now and 2025 unless action is taken to reduce currently high-per-capita urban water consumption. Accordingly, consumption control in the mega-city of Tehran will be an invaluable achievement. A study of Tehran water consumers has determined that household consumers are responsible for 70 percent of the total consumption. Keeping that figure in mind, the authors set out to assess rates of consumption by water fixtures, with an emphasis on household users, and to examine the effects of installing subcounters and reducers. They selected an apartment complex in which it was possible to install water subcounters for each unit. The first step was to evaluate resident attitudes. Block 3, which had 10 units, was selected to cooperate with the project. The second step was to install counters for all 10 units to determine consumption by different fixtures. (The counters were installed in kitchens, in bathrooms, on toilets, on washing machines, and on flash tanks). In the next step, data entry forms for fixture consumption were completed for a period of 10 days. Then single-handle faucets and reducers were installed, and the outcomes were logged for a period of 10 days. Counter readings were performed by the volunteer residents or by educated personnel every 24 hours, and the total volume of inside consumption was compared with the consumption registered by a base counter placed outside each unit. In the course of the project, the consumption per capita was calculated every 24 hours to yield a real and unbiased model that is applicable to city of Tehran. The results showed a total reduction in water consumption of about 20 percent. Thus, with suitable planning and application of cultural and technical methods, it is possible to optimize consumption in Tehran in the near future.

Rodents are an important source of zoonotic diseases for human. The aim of this study was to determine the infectivity of rodents with intestinal helminths in North Khorasan Province, Iran. One hundred and thirteen rodents were collected using different collection methods such as kill and live traps, digging of their burrow, filling of their hiding places with water and hand net during 2011-2013. Their alimentary canals were removed in the laboratory and helminths were determined in the department of parasitology, Tehran University of Medical Sciences. Thirteen species of helminths parasites were found in 13 species of rodents, including Aspiculuris tetraptera, Hymenolepis diminuta, Nippostrongylus brasiliensis, Protospirura Seurat, Rictolaria ratti, Skrjabinitaenia lobata, Streptopharagus kuntzi, Syphacia obvelata, Taenia taeniaeformis, Trichuris muris, Cysticercus fasciolaris, Acanthocephal. spp and Trichuris spp . Some of them were reported for the first time in new host in Iran. S. obvelata and A. tetraptera were the most frequent parasites and P. Seurat, R. ratti and C. fasciolaris were found only in one rodent. This is the first study to investigate the intestinal parasites in rodents in this area. Among different species identified, some of helminths were reported in new host.

Air pollution assessment is an imperative part of megacities planning and control. Hence, a new comprehensive approach for air pollution monitoring and assessment was introduced in this research. It comprises of three main sections: optimizing the existing air pollutant monitoring network, locating new stations to complete the coverage of the existing network, and finally, generating an air pollution map. In the first section, Shannon information index was used to find less informative stations to be candidate for removal. Then, a methodology was proposed to determine the areas which are not sufficiently covered by the current network. These areas are candidates for establishing new monitoring stations. The current air pollution monitoring network of Tehran was used as a case study, where the air pollution issue has been worsened due to the huge population, considerable commuters' absorption and topographic barriers. In this regard, O3, NO, NO2, NOx, CO, PM10, and PM2.5 were considered as the main pollutants of Tehran. Optimization step concluded that all the 16 active monitoring stations should be preserved. Analysis showed that about 35% of the Tehran's area is not properly covered by monitoring stations and about 30% of the area needs additional stations. The winter period in Tehran always faces the most severe air pollution in the year. Hence, to produce the air pollution map of Tehran, three-month of winter measurements of the mentioned pollutants, repeated for five years in the same period, were selected and extended to the entire area using the kriging method. Experts specified the contribution of each pollutant in overall air pollution. Experts' rankings aggregated by a fuzzy-overlay process. Resulted maps characterized the study area with crucial air pollution situation. According to the maps, more than 45% of the city area faced high pollution in the study period, while only less than 10% of the area showed low pollution. This situation confirms the need for effective plans to mitigate the severity of the problem. In addition, an effort made to investigate the rationality of the acquired air pollution map respect to the urban, cultural, and environmental characteristics of Tehran, which also confirmed the results.

Quantum organizations are referred where stakeholders know how to access the infinite potential of the quantum field. Viewing healthcare organizations from perspective of quantum theory suggest new approaches into management techniques for effective and efficient delivery of healthcare services. This research is aimed to determine the quantum skills, quantum leadership characteristics and functions of Tehran University of Medical Sciences hospitals' nursing administrators. A cross-sectional, descriptive and analytical study was conducted among 25 nursing administrators of Tehran University of Medical Sciences (TUMS) hospitals, Tehran, Iran. The research tool for data collection was a self-constructed questionnaire that measured the quantum skills, quantum leadership characteristics and functions of TUMS hospitals' nursing administrators. The validity of questionnaire was confirmed by 5 management science experts and its reliability was performed by using test-retest method yielded a Cronbach's alpha coefficient of 0.90. Data were collected and analyzed by SPSS software and t-test statistical methods. The results of this research showed that all respondents had desired quantum skills (75.71±5.98), quantum leadership characteristics (82.01±6.77), and quantum leadership functions (78.57±6.28) and total quantum leadership (78.76±4.50). Also, passing management training courses of the respondents was significantly correlated with their quantum leadership. Iranian healthcare organizations require quantum leadership that provides an important resource to advance Iranian nursing leadership to the organizational excellence. We hope Iranian hospitals' nursing leaders who have quantum skills potentially, present a highly developed sense of self and the ability to improve nursing care outcomes in these hospitals.

Organizational behaviors are commonly acknowledged as fundamentals of organizational life that strongly influence both formal and informal organizational processes, interpersonal relationships, work environments, and pay and promotion policies. The current study aims to investigate political behavior tendencies among employees of Tehran University of Medical Sciences (TUMS). This cross-sectional, descriptive and analytical study was conducted on 810 TUMS employees at the headquarters of the Tehran University of Medical Sciences, Iran during 2010-2011. The research tool for data collection was a researcher-tailored questionnaire on political behaviors. The validity of the questionnaire was confirmed by seven management professors, and its reliability was tested by a pilot study using test-retest method which yielded a Cronbach's alpha coefficient of 0.71. The respondents were asked to fill the questionnaire and express their perceptions and tendencies to engage in organizational behaviors. The collected data was read to and analyzed by IBM SPSS environment and correlation analytical methods. Overall, 729 respondents filled and returned the questionnaire yielding a response rate of 90%. Most of the respondents indicated that they had no tendency to engage in political behavior. Moreover, we found that there was a significant correlation between sex, higher education degrees, tenure and the employees' tendency to engage in political behavior. The participants were not overtly political because of their personal belief, ethical values, and personal characters. Non-political and overtly political employees are both prejudicial for all organizations. Therefore, it seems that the medium rate of good political behavior is vital and prevalent in Iranian organizations.

Households' financial protection against health payments and expenditures and equity in utilization of health care services are of the most important tasks of governments. This study aims to measuring equity in household's health care payments according to fairness in financial contribution (FFC) and Kakwani indices in Tehran-Iran, 2013. This cross-sectional study was conducted in 2014.The study sample size was estimated to be 2200 households. Households were selected using stratified-cluster sampling including typical families who reside in the city of Tehran. The data were analyzed through Excel and Stata v.11software. Recall period for the inpatient care was 1 year and for outpatient1 month. The indicator of FFC for households in health financing was estimated to be 0.68 and the trend of the indicator was ascending by the rise in the ranking of households' financial level. The Kakwani index was estimated to be a negative number (-0.00125) which indicated the descending trend of health financing system. By redistribution of incomes or the exempt of the poorest quintiles from health payments, Kakwani index was estimated to be a positive number (0.090555) which indicated the ascending trend of health financing system. According to this study, the equity indices in health care financing denote injustice and a descending trend in the health care financing system. This finding clearly shows that deliberate policy making in health financing by national health authorities and protecting low-income households against health expenditures are required to improve the equity in health.

Self esteem (SE) and organizational commitment (OC)? have significant impact on the quality of work life. This study aims to gain a better understanding of the relationships between SE and OC among health information management staff in tertiary care hospitals in Tehran (Iran). This was a descriptive correlational and cross sectional study conducted on the health information management staff of tertiary care hospitals in Tehran, Iran. A total of 155 participants were randomly selected from 400 staff. Data were collected by two standard questionnaires. The SE and OC was measured using Eysenck SE scale and Meyer and Allen's three component model, respectively. The collected data were analyzed with the SPSS (version 16) using statistical tests of of independent T-test, Pearson Correlation coefficient, one way ANOVA and F tests. The OC and SE of the employees' were 67.8?, out of 120 (weak) and 21.0 out of 30 (moderate), respectively. The values for affective commitment, normative commitment, and continuance commitment were respectively 21.3 out of 40 (moderate), 23.9 out of 40 (moderate), and 22.7 out of 40 (moderate). The Pearson correlation coefficient test showed a significant OC and SE was statistically significant (P<0.05). The one way ANOVA test (P<0.05) did not show any significant difference between educational degree and work experience with SE and OC. This research showed that SE and OC ?are moderate. SE and OC have strong correlation with turnover, critical thinking, job satisfaction, and individual and organizational improvement. Therefore, applying appropriate human resource policies is crucial to reinforce these measures.

Oral cancer is a life-threatening disease with low survival rates, especially when diagnosed in an advanced stage. Lack of awareness about this cancer among the population is proposed as a possible reason for this diagnostic delay. The aim of this study was to evaluate oral cancer awareness, as well as the association of this with sociodemographic status in Tehran. In this cross-sectional population-based survey, 1800 self-administered questionnaires (collecting sociodemographic data, questions regarding oral cancer awareness and the source of information) were distributed through multistage stratified random sampling. Scores for questions ranged from 0 to 4, and totals were summed. The outcome of question responses was also analyzed separately. In total, 1312 questionnaires were available for analysis, from 788 females and 489 males (37.8 ± 9.02 years). Only 30% of the respondents were aware of oral cancer. The average score for awareness was 1.09 ± 1.6 with no significant differences between age groups and genders. Almost 6.5% of participants had complete awareness about oral cancer. A significant difference was found between mean scores in different levels of education and occupation (p = 0.0001). From 585 responses to the "source of information" question, "public media" was the most important source (almost 50%). Only 2% mentioned "dentists" as a source of information. This study indicated an alarming lack of oral cancer awareness and literacy in Tehran, Iran. Dentists should be obliged to practice their pivotal role in informing the public about oral cancer.

Hepatitis A virus (HAV) and hepatitis E virus (HEV) are enteric hepatotropic viruses and their prevalence is related to the sanitary conditions of the region under investigation. There are only a few studies on the seroepidemiology of these two viruses in the general Iranian population. The purpose of this investigation was to measure the prevalence of hepatitis A and E infections in the general population. Between 2006 and 2007, a cross sectional study was performed in Tehran, Iran. Blood specimens were collected and questionnaires were filled in for 551 persons. Patient sera were tested by ELISA for anti-HEV and anti-HAV IgGs. The χ(2) test and independent t-test were used for statistical analysis and p<0.05 was considered significant. The overall seroprevalence rates of anti-HEV IgG and anti-HAV IgG were 9.3% and 90%, respectively. The prevalence of antibodies to HAV and HEV was greater among men than women and increased with age. However, there was no significant relationship between age and gender with the existence of anti- HAV and HEV IgG antibodies. Our results show the seroprevalence of HAV and HEV antibodies are high and both viruses are endemic in this region. These findings are in accordance with results obtained from previous studies. We recommend that foreign travelers to Iran are vaccinated against HAV. Copyright © 2012 Royal Society of Tropical Medicine and Hygiene. Published by Elsevier Ltd. All rights reserved.

Brain and SCI Research Center, Neuroscience Institute, Tehran University of Medical Sciences, Tehran, Iran. This was a cross-sectional study. A sample of patients with SCI participated in the study and completed two questionnaires: the Short-Form 36-Item Health Survey (SF-36) in order to collect data on vitality, social functioning, mental health and role emotional and the Spiritual Well-Being Scale (SWBS) to measure religious and existential well-being. The association between spiritual well-being and health-related QOL was then assessed. In all 213 patients were studied. The mean age of patients was 43.5 (SD = 10.8) years, and most were male (77.5%). The results obtained from generalized linear regression analysis indicated that religious well-being and existential well-being were significant contributing factors to improved vitality, social functioning, mental health and role emotional. The findings suggest that having higher levels of spiritual well-being might improve quality of life in people with spinal cord injury.

This was a qualitative study conducted using an interpretative phenomenological approach. This study investigated the experience of pregnancy and childbirth in women with spinal cord injury (SCI). Brain and Spinal Cord Injury Research Center, Tehran University of Medical Sciences, Tehran, Iran. The data were collected using telecommunication and face-to-face semi-structured interviews with eight women with SCI. The study employed the interpretative phenomenological approach suggested by Van Manen in 2016 and thematic analysis to provide a comprehensive understanding of the childbearing experience of women with SCI. MAXQDA 10 software was used to manage the collected data. Five main themes have emerged from data analysis: "revivification", "fear and concern of motherhood with SCI", "flawed health care system", "maternal experience under a supportive umbrella", and "strengthening spirituality and religious belief". Childbearing had a positive effect on the family relationship, continuity of marriage, and quality of life following SCI. There are potential benefits in establishing a center that provides consultation on childbearing and childcare for women with SCI. Moreover, training for the medical team, which includes nurses, midwives, and specialists is highly recommended. Further research is needed to expand our understanding of childbearing from the perspectives of healthcare providers.

To investigate whether the introduction of clinical audits by the Safe Motherhood Committee of a general hospital in Tehran, Iran, influenced cesarean section (CS) rates, A retrospective study was performed. The number of deliveries before and after the institution of clinical audits (May to December 2005) were tabulated in the audited hospital and analyzed by Chi(2) test. Additionally, CS rates were measured in 3 other general hospitals during the same time period for comparison. A total of 3,494 deliveries were recorded during the study periods in 2004 and 2005 at the audited hospital. Subsequent to the audit, the overall CS rate decreased from 40% to 33% (p < 0.001) and the primary CS rate from 29% to 21% (p < 0.001), accounting for a 27% reduction in the risk of primary CS. In 2006 CS rates reverted to 42%. None of the other 3 general hospitals indicated a decline in CS rates in 2005. Our findings show a preventive association between the clinical audits and CS rates in a general hospital. The implementation of a clinical audit process can be an effective way to track care pathways and reduce unnecessary CS deliveries.

Antimicrobial resistance (AMR) adversely impacts the prevention and treatment of a wide range of infections and is considered as a serious threat to global public health. Occupational-related AMR is a neglected area of research. To assess exposure to penicillin dust, penicillin active materials, and to report the frequency of penicillin resistance among pharmaceutical workers in Tehran, Iran. A quasi-experimental study was conducted among workers on a penicillin production line in a pharmaceutical company (n = 60) and workers in a food producing company (n = 60). Data were collected via survey, air sampling, and throat swab. The mean overall concentrations of penicillin dust and penicillin active material were 6.6 and 4.3 mg/m 3 , respectively, in the pharmaceutical industry. Streptococcus pneumoniae (S. pneumoniae) was detected in 45% (27) individuals in the exposed group, 92.6% of which showed penicillin resistance. Resistance was significantly higher among workers in penicillin production line (p = 0.014). High level of AMR among workers in penicillin production line is a health risk for the workers as well as society as a whole through the spread of drug resistant micro-organisms.

Managing Proliferation Issues with Iran

Any government in Tehran will be inclined to seek weapons of mass destruction (WMD) and missile delivery options given the realities of its strategic environment. These weapons might help Iran to deter potential external threats, to achieve equality with other major regional powers armed with WMD, and to attain self-reliance in national security, given the isolating experience of arms embargoes. A more pluralist leadership in the future, however, may examine broader choices and trade-offs, and perhaps be less likely to cross key thresholds in WMD acquisition. In any event, Iran's WMD behavior is likely to be determined by both externalmore » factors, mainly the availability of crucial components, and internal factors, including calculations of costs, risks, and benefits. Among the benefits, psychological factors, such as prestige, will play an important role. Other important factors that might well shape Iran's WMD behavior include developments in Iraq, relations with the United States and other Gulf states, Israeli-Palestinian relations and the future price of oil. This paper offers recommendations on how the United States can best hope to influence Iranian decisions regarding the acquisition of WMD and missile delivery systems if the United States decides to pursue more direct engagement with Tehran. An engagement-nonproliferation strategy should involve at least three types of parallel efforts: public, private and indirect. Public efforts should seek to create a more positive, less-threatening image of the United States among opinion leaders in Iran. Private efforts should seek to determine the purposes, nature and extent of Iran's efforts to develop WMD and missiles and to suggest better alternatives for Iran's security and prestige needs. Indirect efforts should involve key third countries and organizations in an attempt both to address Iran's security concerns and to deny Iran access to critical WMD and missile technology and components. Russian policy, in particular, will continue to play a vital role in determining the extent to which Iran is able to pursue WMD options. Without a fundamental change in the regional security environment, however, there is little reason to expect changes in Iranian WMD and missile policies, and the United States, acting alone and short of war, cannot prevent Iran from ultimately developing WMD and delivery systems. Furthermore, U.S. policies that take a tougher line with Russia, China and North Korea are not likely to lead to more restraint among these potential sources of WMD and missile technology. In the absence of engagement with Iran, unilateral U.S. economic sanctions will remain the principal, if flawed, U.S. policy tool for seeking to prevent Iran from acquiring WMD. The rationale is that by discouraging trade and investment, particularly in Iran's energy sector, the government of Iran will have less revenue to pursue proliferation. Without broad international support for economic isolation, however, such an effort may hinder Iran's WMD programs, though it cannot block them. Finally, options are needed to deal with major failures in nonproliferation efforts. These options include measures to deter Iranian use of WMD, to defend against their use if deterrence fails, and to destroy Iranian WMD capabilities should the need arise.« less

Despite cultural and religious prohibitions against premarital heterosexual relationships and intimacy, some recent evidence suggests some rise in premarital heterosexual interactions and relationships among young people. On the other hand, although HIV in Iran is a concentrated epidemic and mainly reported among high risk groups such as injecting drug users (IDUs), but there are evidences that the mode of transmission is shifting towards sexual contacts. This trend has caused concern among health policy makers in terms of prevention of STDs and HIV/AIDS particularly, among young people. This paper was prepared with the aim of highlighting how gender contributes to variation in reproductive health needs and conduct of young people in Iran. This paper is based on a secondary analysis and compares comparable reproductive beliefs and conducts of women and men based on the data of two surveys conducted in Tehran in 2002 and 2005. A survey among 1385 adolescent males and another survey among 1743 female undergraduate students in four multidisciplinary universities in Tehran. Both surveys used anonymous self-administered questionnaires. To make the two samples comparable, the data of unmarried female university undergraduate students who resided in Tehran were merged with the data of adolescent male students who intended to pursue higher education. Common variables of the two surveys were identified, homogenized, merged and analysed. Reproductive health knowledge among male adolescents was poor compared to that of their female peers. Although premarital friendships were moderately acceptable from view points of both males and females, the majority were against premarital sex, particularly among female participants. There were evidences of gender-based double standards in perceptions of premarital sexuality among both males and females; particularly, it was stronger among males than females. Male adolescents reported earlier and greater experiences of premarital heterosexual intimacy and sexual contact than females. Multiple partners were also more common among males than females. Females had a tendency to regret first sexual contact more than males, which reflects that first sex is more likely to be unplanned and unwanted among females compared to males. Significant gender-based double standards prevailed current sexual attitudes and conduct of young people in Iran. Gender norms which encourage unmarried men to practice premarital sex lead to an earlier transition of men to sexual relations and multiple sexual partners. Due to poor knowledge and various misconceptions about sexual health and lack of consistent contraceptive and condom use among adolescents and young people in Iran, both young men and women are susceptible to sexual and reproductive health hazards such as sexually transmitted infections (STIs), HIV/AIDS, pregnancy and unsafe abortion. Changing gender norms associated with sexuality may lead to promotion of safer sexual behaviors particularly among young people. Current reproductive health and HIV prevention programs should take into account gender-based double standards among young people and their unmet reproductive health needs.

Crimean-Congo hemorrhagic fever (CCHF) is viral hemorrhagic fever caused by CCHF virus, which belongs to the family Bunyaviridae and the genus Nairovirus. The virus is transmitted to humans via contact with blood and tissue from infected livestock, a tick bite, or contact with an infected person. Since 2000, we have shown the disease to be prevalent in 23 out of 30 provinces of Iran. Among those, Sistan-va-Baluchistan, Isfahan, Fars, Tehran, Khorasan, and Khuzestan demonstrated the highest infection, respectively. Notably, Sistan-va-Baluchistan province, southeast of Iran, has the highest prevalence of CCHF, and has shown to be present since at least 2000. Phylogenetic study of the CCHF virus genome isolated from Iranian patients showed a close relationship with the CCHF Matin strain (Pakistan). Our epidemiological data in the last decade have implied that the severity and fatality rate of the disease has ranged variably in different provinces of Iran. More pathogenesis and phylogenetic studies should therefore be investigated to clarify these differences.

The vertical concentration profiles and source contributions of polycyclic aromatic hydrocarbons (PAHs) and n-alkanes in respirable particle samples (PM4) collected at 10, 100, 200 and 300-m altitude from the Milad Tower of Tehran, Iran during fall and winter were investigated. The average concentrations of total PAHs and total n-alkanes were 16.7 and 591 ng/m(3), respectively. The positive matrix factorization (PMF) model was applied to the chemical composition and wind data to apportion the contributing sources. The five PAH source factors identified were: 'diesel' (56.3% of total PAHs on average), 'gasoline' (15.5%), 'wood combustion, and incineration' (13%), 'industry' (9.2%), and 'road soil particle' (6.0%). The four n-alkane source factors identified were: 'petrogenic' (65% of total n-alkanes on average), 'mixture of petrogenic and biomass burning' (15%), 'mixture of biogenic and fossil fuel' (11.5%), and 'biogenic' (8.5%). Source contributions by wind sector were also estimated based on the wind sector factor loadings from PMF analysis. Directional dependence of sources was investigated using the conditional probability function (CPF) and directional relative strength (DRS) methods. The calm wind period was found to contribute to 4.4% of total PAHs and 5.0% of total n-alkanes on average. Highest average concentrations of PAHs and n-alkanes were found in the 10 and 100 m samples, reflecting the importance of contributions from local sources. Higher average concentrations in the 300 m samples compared to those in the 200 m samples may indicate contributions from long-range transport. The vertical profiles of source factors indicate the gasoline and road soil particle-associated PAHs, and the mixture from biogenic and fossil fuel source-associated n-alkanes were mostly from local emissions. The smaller average contribution of diesel-associated PAHs in the lower altitude samples also indicates that the restriction of diesel-fueled vehicle use in the central area of Tehran has been effective in reducing the PAHs concentration.

Background: Electrical burns account for a significant percentage of fatal accidents. Each year, a number of consumers in Iran suffer from electrical injuries due to technical problems, equipment failures, and the unauthorized use of electricity. The aim of this study was to examine the root causes of accidents that involved electricity in the district served by the Western Tehran Province Electricity Distribution Company. Methods: This was a descriptive study in which incidents involving electricity-related injuries were investigated among customers served by the Western Tehran Province Electricity Distribution Company. Therefore, we collected and analyzed incident reports filed by citizens from 2005 through the first half of 2009 in the Distribution Company’s coverage area, including Savejbolagh, Shahriyar, eastern Karaj, Qods City, southern Karaj, western Karaj, Malard, and Mehrshahr. The reported events were analyzed using SPSS software. Results: Exposure of electricity lines and unauthorized construction of residential houses in areas where there were medium- and low-voltage lines were responsible for 37% of the injuries. The findings showed that the highest rate of accidents occurred in 2008 and the first half of 2009. The highest rate of accidents occurred among people with a mean age of 35. Conclusion: The results from investigating the causes of electrical accidents emphasized the necessity of developing a culture of safety in communities, especially among employees who are engaged in occupations related to electricity, construction workers, and school children to reduce the rate of such accidents.

Implementation of patient feedback is considered as a critical part of effective and efficient management in developed countries. The main objectives of this study were to assess patient satisfaction with the services provided in hospitals affiliated to Tehran University of Medical Sciences, Iran, identify areas of patient dissatisfaction, and find ways to improve patient satisfaction with hospital services. This cross-sectional study was conducted in 3 phases. After 2 initial preparation phases, the valid instrument was applied through telephone interviews with 21476 participants from 26 hospitals during August, 2011 to February, 2013.Using the Satisfaction Survey tool, information of patient's demographic characteristics were collected and patient satisfaction with 15 areas of hospital services and the intent to return the same hospitals were assessed. The mean score of overall satisfaction with hospital services was 16.86 ± 2.72 out of 20. It was found that 58% of participants were highly satisfied with the services provided. Comparison of mean scores showed physician and medical services (17.75 ± 4.02), laboratory and radiology services (17.67 ± 3.66), and privacy and religious issues (17.55 ± 4.32) had the highest satisfaction. The patients were the most dissatisfied with the food services (15.50 ± 5.54). It was also found that 83.7% of the participants intended to return to the same hospital in case of need, which supported the measured satisfaction level. Patient satisfaction in hospitals affiliated to Tehran University of Medical Sciences was high. It seems that the present study, with its large sample size, has sufficient reliability to express the patient satisfaction status. Moreover, appropriate measures should be taken in some areas (food, cost, and etc.) to increase patient satisfaction. PMID:27471589

Nowadays, hospitals have turned increasingly towards the Internet and develop their own web presence. Hospital Websites could be operating as effective web resources of information and interactive communication mediums to enhance hospital services to the public. Therefore, the aim of this study was to assess the quality of websites in Tehran's public hospitals. This cross-sectional analysis involved all public hospitals in Iran's capital city, Tehran, with a working website or subsites between April and June, 2014 (N=59). The websites were evaluated using three validated instruments: a localized checklist, Google page rank, and the Alexa traffic ranking. The mentioned checklist consisted of 112 items divided into five sections: technical characteristics, hospital information and facilities, medical services, interactive on-line services and external activities. Data were analyzed using descriptive and analytical statistics. The mean website evaluation score was 45.7 out of 224 for selected public hospitals. All the studied websites were in the weak category based on the earned quality scores. There was no statistically significant association between the website evaluation score with Google page rank (P=0.092), Alexa global traffic rank and Alexa traffic rank in Iran (P>0.05). The hospital websites had a lower quality score in the interactive online services and external activities criteria in comparing to other criteria. Due to the low quality level of the studied websites and the importance of hospital portals in providing information and services on the Internet, the authorities should do precise planning for the appreciable improvement in the quality of hospital websites.

Published studies on dermatological emergencies are limited in the literature. To our knowledge, no study has previously explored this subject in Iran. Our aim was to ascertain the characteristics of patients visiting the dermatologic emergency (DE) unit of a university skin hospital in Tehran, Iran. We studied the files of all the patients seen in the DE unit over a 3-month period, collecting data on age, sex, referral mode, duration of consultation, status (true emergency or non-emergency), and diagnosis. A total of 2539 patients were evaluated; 53% of them were female. Infection and infestation (41.9%), urticaria (16.7%), and dermatitis (13.2%) were the most prevalent entities. Almost 1% of the patients were referred by another physician and psoriasis was their most frequent diagnosis. Almost 2.6% of the patients were hospitalized; psoriasis was once again the most frequent cause. The hospitalization rate was significantly higher in referred patients (P<0.001). A sampling bias may have occurred due to the time interval (three summer months) of the study. The majority of the patients did not require emergency consultation. Even the most prevalent acute conditions such as bite, urticaria, infections, and infestations could be diagnosed and easily managed by general practitioners. The presented data showed a need for improvement in the non-dermatologist physicians' knowledge of emergency dermatologic disorders. This data could also help in tailoring the educational curriculum for medical students more appropriately in order to increase their knowledge of the most prevalent skin disorders.

Perceived service quality is the most important predictor of patient satisfaction. The purpose of this study was to investigate the impact of the service quality on the overall satisfaction of patients in private hospitals of Tehran, Iran. This cross-sectional study was conducted in the year 2010. The study's sample consisted of 969 patients who were recruited from eight private general hospitals in Tehran, Iran using consecutive sampling. A questionnaire was used for data collection; contacting 21 items (17 items about service quality and 4 items about overall satisfaction) and its validity and reliability were confirmed. Data analysis was performed using t-test, ANOVA and multivariate regression. this study found a strong relationship between service quality and patient satisfaction. About 45% of the variance in overall satisfaction was explained by four dimensions of perceived service quality. The cost of services, the quality of the process and the quality of interaction had the greatest effects on the overall satisfaction of patients, but not found a significant effect on the quality of the physical environment on patient satisfaction. Constructs related to costs, delivery of service and interpersonal aspect of care had the most positive impact on overall satisfaction of patients. Managers and owners of private hospitals should set reasonable prices compared to the quality of service. In terms of process quality, waiting time for visits, admissions, and surgeries must be declined and services provided at the fastest possible time. It should be emphasized to strengthen of interpersonal aspects of care and communication skills of care providers.

Subway transportation system is a new phenomenon in Iran. Noise annoyance interferes with the individual's task performance, and the required alertness in the driving of subway trains. This is the first study conducted to measure the level of noise and noise annoyance among conductors of subway organization in Tehran, Iran. This cross sectional study was conducted among 167 randomly selected train conductors. Information related to noise annoyance was collected by using a self-administered questionnaire. The dosimetry and sound metering was done for the conductors and inside the cabins. There were 41 sound metering measuring samples inside the conductors' cabin, and there were 12 samples of conductors' noise exposure. The results of sound level meter showed that the mean Leq was 73.0 dBA ± 8.7 dBA and the dosimetry mean measured Leq was 82.1 dBA ± 6.8 dBA. 80% of conductors were very annoyed/annoyed by noise in their work place. 53.9% of conductors reported that noise affected their work performance and 63.5% reported that noise causes that they lose their concentration. The noise related to movement of train wheels on rail was reported as the worst by 83.2% followed by the noise of brakes (74.3%) and the ventilation noise (71.9%). 56.9% of conductors reported that they are suffering from sleeplessness, 40.1% from tinnitus and 80.2% feeling fatigue and sleepy. The study results showed the high level of noise and noise annoyance among train conductors and the poor health outcome of their exposure to this level of noise.

Increasing development of mobile communication infrastructure while enhancing availability of the technology raises concerns among the public, who see more cell towers erected each day, about possible health effects of electromagnetic radiations. Thereon, a survey of radio-frequency radiation from 60 GSM base stations was carried out in Tehran, Iran at several places mostly located in major medical and educational centres. Measurements were performed at 15 locations near each base station site, i.e. 900 locations in total. Since there are other RF radiation sources such as broadcasting services whose carrier frequencies are <3 GHz, the whole band of 27 MHz to 3 GHz has been assessed for hazardous exposures as well. The results were compared with the relevant guideline of International Commission on Non-Ionising Radiation Protection and that of Iran, confirming radiation exposure levels being satisfactorily below defined limits and non-detrimental.

Diabetes is a common problem in older adults, as they increasingly comprise a larger proportion of patients newly diagnosed with diabetes. The evidence on the prevalence and distribution of type 2 diabetes (DT2) and its related factors among older adults in Iran is sparse. The aim of the present study was to determine the prevalence of DT2 among Iranian older adults aged ≥60years. The study was part of a comprehensive survey (Urban HEART-2) which was a large population-based cross-sectional study. A multistage cluster random sampling method was used to select the participants in Tehran in 2011. All the participants were interviewed by trained personnel using a standard questionnaire on diabetes as well as a socio-demographic checklist. Logistic regression and chi-square were used to investigate the association between diabetes and the demographic characteristics. A total of 15069 older adults were included in this analysis. The mean age of the participants was 68.93±7.27years (SE: 0.059) and the mean of BMI was 26.21±4.40kg/m 2 (SE: 0.036). Prevalence of DT2 was 14.4% among Iranian older adults. Factors such as age, being female, high BMI, and education were significantly associated with DT2. Given the high prevalence of diabetes among older people, more population based research is needed to quantify the ramifications of diabetes, and to monitor the effects of prevention and health system strengthening strategies on the prevalence, treatment, and control of DT2.

Pain is an important component of disability problems, and plays a key role in mental health of older adults. This study aims to investigate the relationship between mental health and pain in older adults of Tehran, Iran. This was a cross-sectional study using data on 5326 older adults aged ≥60 years old from a large population-based survey (Urban HEART-2). A multistage cluster random sampling method was used to select the participants in Tehran, Iran, in 2011. General Health Questionnaire (GHQ-28), pain questionnaire, and socioeconomic questionnaires were used to collect the data. A total of 5326 older adults, 3811 (71.6%) married and 2797 (52.5%) female, were included into the study. The mean age of the participants was 68.92 ± 7.02 years. Mean of GHQ-28 scores in the sample was 51.08 ± 10.94, which indicates of a good level of mental health. The majority of the older adults had knee and back pain (more than 50%). Regardless of the chronicity, time, and the mode of reaction to it, knee and back pain were the highly reported pains among the participants. There was a statistically significant difference between two groups of older adults, with and without pain, in terms of GHQ-28 scores. Multiple regression analysis revealed that there was a relationship between mental health and the following factors: pain in head, shoulder, teeth, upper and lower limbs, education, gender, age, and marital status. Whatever the explanation, the relation of lowered health status to pain in all body parts among older people is considerable. This renders this matter as a top priority in health policy making.

Background: Students, clergymen and teachers as role models can be very important in encouragement or prevention of cigarette smoking in young people. The aim of this study was to compare prevalence of smoking in 3 male groups of teachers, clergymen and university students. Also, study their knowledge and attitude towards it and the prediction of their future consumption. Methods: In a cross sectional study in 2009 in Tehran, Iran, 1,271 male students, 549 clergymen and 551 teachers were randomly enrolled. Each participant completed the global adult tobacco survey questionnaire. Knowledge, attitude and prediction of smoking for the next 5 years were questioned in these 3 groups. Chi-squared test and logistic regression were used for analysis. P < 0.05 was considered significant. Results: Prevalence of cigarette smoking was 31.1%, 21.9% and 27.2% among students, clergymen and teachers, respectively. Smoking in students was not associated with poor knowledge but were in teachers and clergymen. The odds ratio of smoking in students, clergymen and teachers was higher among those with having inappropriate attitude towards it (OR = 1.6, 6.1 and 4.5). Those with poor knowledge had an inappropriate attitude and predicted higher chance of cigarette consumption in the next 5 years (P < 0.0001). Inappropriate attitude in all 3 groups resulted in higher prediction of future smoking (P = 0.008). Conclusions: This study revealed that the prevalence of smoking among male students and teachers was higher than general population and clergymen who equally smoked. Also, level of knowledge and attitude of students were lower than teachers and clergymen. PMID:23930167

Purpose: To describe long-term outcomes and complications of Ahmed glaucoma valve (AGV) implantation in subjects with refractory glaucoma at Farabi Eye Hospital, Tehran, Iran. Materials and Methods: This retrospective cohort study evaluated patient records of all subjects with refractory glaucoma who had undergone AGV implantation up to January 2013. The main outcome measure was the surgical success rate. Complete success was defined as intraocular pressure (IOP) <22 mmHg, without anti-glaucoma medications or additional surgery. Qualified success was IOP <22 mmHg regardless of number of anti-glaucoma medications. In all cases, loss of vision (no light perception) was considered an independent indicator of failure. Data were also collected on intraoperative and postoperative complications. Results: Twenty-eight eyes were included in the study. With a mean follow-up of 48.2 ± 31.7 months (median: 40.50 months; range: 3–124 months), the IOP decreased from a mean preoperative value of 30.8 ± 5.6 mmHg to 20.0 ± 6.4 mmHg at last visit. The number of medications decreased from 3.7 ± 0.4 preoperatively to 2.5 ± 1.1 postoperatively. Cumulative qualified success was achieved in 69% of eyes. Mean time to failure according to qualified success criteria was 92.3 ± 9.4 months. Postoperative complications were recorded in 16 (57.1%) eyes. The most common complication was focal endothelial corneal decompensation at the site of tube-cornea touch. Conclusion: AGV implantation with adjunctive topical anti-glaucoma drops controlled IOP in approximately 70% of eyes with refractory glaucoma with a median of 40.5 months of follow-up. However, complication rates were higher. PMID:26957848

Objective We aimed to compare the medical students’ attitude towards psychiatry before and after psychiatry clerkship, and to examine the association of choosing psychiatry as a future career with some personal characteristics. Method In a self-controlled, quasi-experimental study, all of the medical students entering the psychiatry clerkship in three major medical schools of Iran located in Tehran (Tehran, Shahid Beheshti, and Iran University of Medical Sciences) were asked to participate anonymously in the study on the first and the last 3-days of their psychiatry clerkship. From 346 invited 4th-5th year medical students, 225 (65%) completed anonymous self-report questionnaires before and after a 4-week psychiatry clerkship. Results Positive response to choose psychiatry as a career was seen in 13.3% and 18.3% before and after psychiatry rotation, respectively. However, the difference was not statistically significant; about one-quarter of the students were turned on to psychiatry and 25% were discouraged during the clerkship. Individual pair wise comparisons revealed significant improvements only in two out of 13 measured aspects of psychiatry. Seventeen out of 38 (47.7%) students who identified psychiatry as the career of choice or strong possibility reported that one of their family members or close friends’ mental illness had an impact on their choice. Those students who considered psychiatry as the strong possibility claimed that they are more interested in humanities (OR = 2.96; 95% CI: 1.17, 7.49), and playing a musical instrument (OR = 2.53; 95% CI: 1.15, 5.57). Conclusion It may be concluded that exposure to psychiatry clerkship could influence medical students’ opinion about psychiatry positively, or negatively. Personal characteristics and individual interests of students may play an important role in choosing psychiatry as their future career. PMID:23682250

As a threat for transportation system, traffic crashes have a wide range of social consequences for governments. Traffic crashes are increasing in developing countries and Iran as a developing country is not immune from this risk. There are several researches in the literature to predict traffic crash severity based on artificial neural networks (ANNs), support vector machines and decision trees. This paper attempts to investigate the crash injury severity of rural roads by using a hybrid clustering and classification approach to compare the performance of classification algorithms before and after applying the clustering. In this paper, a novel rule-based genetic algorithm (GA) is proposed to predict crash injury severity, which is evaluated by performance criteria in comparison with classification algorithms like ANN. The results obtained from analysis of 13,673 crashes (5600 property damage, 778 fatal crashes, 4690 slight injuries and 2605 severe injuries) on rural roads in Tehran Province of Iran during 2011-2013 revealed that the proposed GA method outperforms other classification algorithms based on classification metrics like precision (86%), recall (88%) and accuracy (87%). Moreover, the proposed GA method has the highest level of interpretation, is easy to understand and provides feedback to analysts.

This research is aimed at developing a model for assessing land use compatibility in densely built-up urban areas. In this process, a new model was developed through the combination of a suite of existing methods and tools: geographical information system, Delphi methods and spatial decision support tools: namely multi-criteria evaluation analysis, analytical hierarchy process and ordered weighted average method. The developed model has the potential to calculate land use compatibility in both horizontal and vertical directions. Furthermore, the compatibility between the use of each floor in a building and its neighboring land uses can be evaluated. The method was tested in a built-up urban area located in Tehran, the capital city of Iran. The results show that the model is robust in clarifying different levels of physical compatibility between neighboring land uses. This paper describes the various steps and processes of developing the proposed land use compatibility evaluation model (CEM).

People are increasingly interested in health news. As a mass media, the 'Islamic Republic of Iran Broadcasting' (IRIB) has the highest number of target audiences. In Iran, some people follow health news via health programs on satellites and other means of communication. However, all of these programs do not live up to the standards of scientific evidence. In this study, we examined Tehran people's trust in health news disseminated by the IRIB and other mass media outlets. A cross-sectional study was conducted in Tehran. Through multistage sampling, 510 households proportional to size were randomly selected from five regions of Tehran including northern, eastern, western, southern and central regions. One person from each household completed the questionnaire through interviews. The questionnaire included questions on people's level of trust in health news delivered by the IRIB, satellite programs, the internet and magazines. It also included demographic questions. The validity and reliability of the questionnaire was evaluated. Among the interviewees, 50.6% was female. The highest level of trust by the participants was observed in the IRIB (65.2%), and the lowest trust was observed in satellite news (43.4%); p< 0.001. The interviewees believed that the IRIB news broadcasters had more mastery over the subject than the ones in satellite channels (p< 0.001). The IRIB's coverage of important and relevant health topics was also significantly perceived to be better than that of satellite news (p< 0.001). According to 83.5% of interviewees, the quality of health news had improved in the past 10 years. Fifty nine point eight percent of participants believed the quality and accuracy of the IRIB health news was monitored. People's higher level of trust in domestic news as compared to foreign sources and the better status of domestic sources in other areas such as precision in reporting, coverage of more important news, its delivery in lay language, the news broadcasters' proficiency, and other cases - from the participants' point of view - can highlight the significance of designing interventions for changing health behavior among domestic health news producers. Therefore, the results of this study can prove useful to health news policy makers in the IRIB.

Red blood cell alloimmunization is common in patients receiving multiple blood transfusions. Since the probability of repeat transfusion increases with longer life expectancy, it is important to study to which extent alloimmunized patients with a history of transfusion are prone to form alloantibodies after transfusion events. The aim of this study was to retrospectively analyze the alloimmunization against RBCs among transfused patients who were to undergo elective surgery in Tehran, Iran. A total of 3092 occasionally transfused patients, who were to undergo elective surgery, in four hospitals in Tehran were included in the study. For patients with alloantibodies, the data about sex, date of birth, history of transfusion, surgery, abortion and alloantibody specificity were collected. Clinically significant alloantibodies were found in 30 patients. The presence of positive antibodies in the patients for whom cross-match had been done was one per cent. Most of them had surgery history or transfusion record during the preceding year. The three most frequent alloantibodies were anti-K (23.53%), anti- E (20.59%) and anti-c (17.56%). The most common clinically significant alloantibodies identified in men and women were anti-K and anti-E, respectively. The most common causes of alloimmunization for men were surgery history and transfusion record and for women pregnancy.

A large number of dead bodies are referred to forensic autopsy halls for medicolegal examination. They can be a source of transmission of infectious diseases through direct contact or autopsy tools. The main aim of this study was to estimate the virus infection rates in the dead bodies. One thousand consecutive dead bodies that had been referred to autopsy hall of Legal Medicine Bureau of Tehran, Iran, during 2016, were included. The blood samples were analyzed in the laboratory for detection of HBs Ag, HBs Ab, HIV Ab, and HCV Ab, after providing informed consent from legal next of kin of the dead bodies. The general characteristics of the dead bodies were also collected by a checklist. Forty-seven cases of HIV seropositivity, 80 cases of HBs Ag seropositivity, and 97 cases for HCV Ab seropositivity were found. Among them, 27 cases of HIV, 40 cases of anti-HBC positive, and 94 cases of RIBA testing positive for HCV were proved through confirmatory tests. In other words, 2.6% of the dead bodies were infected with HIV, 3.8% with HBV, and 9% with HCV. The total infection rate was 15.5%. This is a worrying risk for pathologist and autopsy technicians.

Background: People with disability experience various problems to access to healthcare services. This study aimed to identify cultural barriers in access to healthcare services for people with disability in Iran. Methods: We conducted a qualitative study using content analysis to identify the cultural barriers. We used semi-structured interviews to collect data. Participants were selected through purposeful sampling with maximum variation. 50 individual interviews were conducted with three groups of people with disability, healthcare services providers and policy makers, September to May 2015, at different locations in Tehran, Iran. Results: We identified a number of different cultural barriers in access to health services for people with disability in Iran. These related to health service providers, namely reluctance to provide health services and disrespect; related to People with disability, namely denial of disability, disproportionate expectation, shame and insufficient sociocultural supports; and related to policy makers, namely lack of concern, little attention to the culture of disability and discrimination. We categorized misconception as a barrier that was observed at all levels of the society. Conclusion: Disability is a reality that some human being may experience and live with it. The negative attitude towards people with disability has a close relationship with the cultural norms of a society. The culture of disability in different dimensions should be a priority for all policy makers. Removing cultural barriers in access to healthcare for people with a disability needs collective efforts and collaborations among all stakeholders.

Background: This study aimed to investigate the relationship between health Related quality of life (HRQOL), motor ability and weight status in children. Methods: Two hundred forty children ages 9–11 yr who were selected via multi stage cluster sampling design from primary schools in the Shahre Qods at Tehran, Iran in 2007. HRQOL was assessed by the pediatric quality of life inventory (PedsQL). Motor abilities were determined by a Basic Motor Ability Test (BMAT). Body mass index was calculated to determine weight status. Results: Psychosocial, physical, and total health related qualities of life (all P< 0.05) were significantly lowered for obese when compared to normal weight participants. In contrast, the mean scores for each HRQOL domain in motor ability category were not significant. No significant interaction was apparent when examining HRQOL scores, BMAT variables and weight status. Conclusion: Regardless of motor ability levels, reducing body weight among children is a potential avenue for promoting improved HRQOL. Over weight boys reported significantly worse school performance than over weight girls, suggesting the importance in considering such dimensions in programs aimed at further understanding obesity in children.

Hospital managers should have enough managerial competencies to coordinate the complex environment. The underlying assumption is that there is a potential gap in management capacity between public and private hospitals in Iran. This study aims to evaluate competency level of hospital managers and to compare their competencies in public and private hospitals. This study was descriptive-analytic, carried out in 2015. A survey using a self-administered questionnaire was conducted among 127 public and private hospitals managers in Tehran Province, Iran. Respondents were asked to rate their competencies in a five-key subscale that included people-related skills, health delivery, self-management, task-related skills, and strategic planning and management. Ratings were based on a five-point Likert scale ranging from very low to excellent competency level. Self-assessment of competencies level showed that managers in all state hospitals evaluate their competency at a low level. Managers felt most competent in health-delivery skills (3.71), people-related skills (3.61), and strategic planning and management (3.57), relatively less competent in self-management (3.54) and task-related skills (3.49). While being the mean total competency levels were significantly higher among male managers, those who participated in the healthcare/hospital management training courses, and those whose primary formal qualification was management in healthcare/hospital management (P<0.05). Similarly, managers who had more experience in their current position were more likely to report higher competencies level (P<0.05). Managers in private hospitals perceived themselves to be significantly more competent than their public hospitals colleagues in most of the management facets (P<0.001). There is a perceived lack of management capacity by managers of both public and private hospitals and the gap between public and private hospitals is small. There is widespread need for management training to be made available in Iran.

The SF-12v2 is the improved version of the SF-12v1. This study aimed to validate the SF-12v2 in Iran. A random sample of the general population aged 18 years and over living in Tehran, Iran completed the instrument. Reliability was estimated using internal consistency and validity was assessed using known-groups comparison and convergent validity. In addition the factor structure of the questionnaire was extracted by performing both exploratory and confirmatory factor analyses (EFA and CFA). In all, 3685 individuals were studied (1887 male and 1798 female). Internal consistency for both summary measures was satisfactory. Cronbach's α for the Physical Component Summary (PCS-12) was 0.87 and for the Mental Component Summary (MCS-12) it was 0.82. Known-groups comparison showed that the SF-12v2 discriminated well between men and women and those who differed in age and educational status (P < 0.05). Furthermore, as hypothesized the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12, while the vitality, social functioning, role emotional and mental health subscales correlated higher with the MCS-12. Finally the exploratory factor analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 59.9% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). Although the findings could not be generalized to the Iranian population, overall the findings suggest that the SF-12v2 is a reliable and valid measure of health related quality of life among Iranians and now could be used in future health outcome studies. However, further studies are recommended to establish its stability, responsiveness to change, and concurrent validity for this health survey in Iran.

An explicitly height-dependent model has been used to estimate the solar irradiation over Iran which has a vast range of altitudes. The parameters of the model have been chosen on general grounds and not by parameters best fitting to any of the available measured irradiation data in Iran. The estimated global solar irradiation on the horizontal surface shows a very good agreement (4.1% deviation) with the 17-year long pyranometric measurements in Tehran, and also, is in good agreement with other, shorter available measured data. The entire data base of the Iranian meteorological stations have been used to establish a simplemore » relation between the sunshine duration records and the cloud cover reports which can be utilized in solar energy estimations for sites with no sunshine duration recorders. Clear sky maps of Iran for direct solar irradiation on tracking, horizontal, and south-facing vertical planes are presented. The global solar irradiation map for horizontal surface with cloudiness is zoned into four irradiation zones. In about four-fifths of the land in Iran, the annual-mean daily global solar irradiation on horizontal surface ranges from 4.5 to 5.4 kWh/m[sup 2].« less

Aim: The quality of services plays a primary role in achieving patient satisfaction. The main purpose of this study was to explore the effect of outpatient service quality on patient satisfaction in teaching hospitals in Iran. Methods: this cross-sectional study was conducted in 2014. The study sample included 500 patients were selected with systematic random method from the outpatient departments (clinics) of four teaching hospitals in Tehran. The survey instrument was a questionnaire consisted of 44 items, which were confirmed its reliability and validity. The data were analyzed by using descriptive statistics, Pearson’s correlation, and multivariate regression methods with the SPSS.18 software. Results: According to the findings of this study, the majority of patients had a positive experience in the outpatient departments of the teaching hospitals and thus evaluated the services as good. Perceived service costs, physician consultation, physical environment, and information to patient were found to be the most important determinants of outpatient satisfaction. Conclusion: The results suggest that improving the quality of consultation, providing information to the patients during examination and consultation, creating value for patients by reducing costs or improving service quality, and enhancing the physical environment quality of the clinic can be regarded as effective strategies for the management of teaching hospitals toward increasing outpatient satisfaction.

This basin supplies water for major agricultural activities and large hydropower production in five Iranian provinces with the total population of four million people. Due to development and population growth, this large trans-boundary basin is incapable of meeting the water demands of the five riparian provinces, causing water allocation conflicts in the region. The situation has been exacerbated by the frequent droughts and is expected to worsen further by climate change. This study evaluates the impacts of climate change on water supply reliability and allocation in this basin. First, outputs of several General Circulation Models (GCMs) under different emission scenarios for different future time horizons are statistically downscaled. Then multiple river flow time series (RFTS) are generated by feeding GCM outputs into a HEC-HMS model, using the Soil Moisture Accounting (SMA). Given a wide range of variations in GCM outputs and the resulting RFTS, the Ward's method is used to identity different RFTS clusters. Clustering helps with increasing the ability of the modeler to test a range of possible future conditions while reducing the redundancies in input data. Karkheh river basin's ability to meet the growing demand under decreasing flows is evaluated for each RFTS cluster representative. Results indicate that Karkheh river flow might decrease by 50% toward the end of the century. This would decrease the reliability of agricultural water deliveries from 78-95% to less than 50%. While currently hydropower dams can only use 50% of their generation capacity for electricity production due to limited water availability, this figure would reduce to less than 30% with climate change. Several adaptation strategies are suggested based on the findings to minimize the economic losses of climate change in this developing basin.

Land use regression (LUR) has not been applied thus far to ambient alkylbenzenes in highly polluted megacities. We advanced LUR models for benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene (BTEX), and total BTEX using measurement based estimates of annual means at 179 sites in Tehran megacity, Iran. Overall, 520 predictors were evaluated, such as The Weather Research and Forecasting Model meteorology predictions, emission inventory, and several new others. The final models with R 2 values ranging from 0.64 for p-xylene to 0.70 for benzene were mainly driven by traffic-related variables but the proximity to sewage treatment plants was present in all models indicating a major local source of alkylbenzenes not used in any previous study. We further found that large buffers are needed to explain annual mean concentrations of alkylbenzenes in complex situations of a megacity. About 83% of Tehran's surface had benzene concentrations above air quality standard of 5 μg/m 3 set by European Union and Iranian Government. Toluene was the predominant alkylbenzene, and the most polluted area was the city center. Our analyses on differences between wealthier and poorer areas also showed somewhat higher concentrations for the latter. This is the largest LUR study to predict all BTEX species in a megacity.

From November 1954 to November 1956, Canadian nurse Margaret Campbell Jackson was employed by the World Health Organization (WHO) and was stationed in Tehran, Iran, where she participated in the establishment of a Maternal and Child Health (MCH) Centre. The objective of the project, known as Iran 10, was twofold: to set up a health service for mothers and children and to initiate a field training program for Iranian physicians, nurses, and other health care providers. Drawing on 180 letters Jackson wrote to her family in Canada from Iran, this article analyzes the MCH Centre as a contact zone and considers the relationships Jackson developed with staff affiliated with the project. The Centre became a space of cross-cultural encounters, where locally and foreign-trained Iranian staff and expatriates mingled and shared working relationships. I argue that authority was negotiated and contested through interactions and associations that were often unequal and framed by notions of progress, modernization, race, and health. Personality also played an important role.

To understand the molecular epidemiology of HIV-1 infection in Iran, we conducted the first study to analyze the genome sequence of Iranian HIV-1 isolates. For this cross-sectional study, we enrolled 10 HIV-1-infected individuals associated with injection drug use from Tehran, Shiraz, and Kermanshah. Near full-length genome sequences obtained from their plasma samples were used for phylogenetic tree and similarity plotting analyses. Among 10 isolates, nine were clearly identified as CRF35_AD and the remaining one as CRF01_AE. Interestingly, five of our Iranian CRF35_AD isolates made two clusters with 10 Afghan CRF35_AD isolates in a phylogenetic tree, indicating epidemiological connections among injection drug users in Iran and Afghanistan. In contrast, our CRF01_AE isolate had no genetic relationship with any other CRF01_AE isolates worldwide, even from Afghanistan. This study provides the first genomic evidence of HIV-1 CRF35_AD predominance and CRF01_AE infection among individuals associated with injection drug use in Iran.

Sexual transmission of HIV/AIDS among women is growing in the Middle East region. Despite the fact that there are numerous gender-related sociocultural factors influencing HIV/AIDS protective behaviors, little gender-specificity is carried out in HIV prevention in Iran. In order to close this gap, we aimed to provide preliminary work that explored the perceptions that women at risk of HIV had about gender norms and gendered power and their ability to protect themselves against HIV/AIDS. Twenty-five semi-structured in-depth interviews were conducted with women at risk of HIV/AIDS, aged 21-49 years, at Voluntary Counseling and Testing Centers or Drop in Centers in Tehran, Iran. Results showed that perceived gender norms were essential barriers of protective behavior through sexual socialization, male control over condom use and sexual decision-making, male pleasure predominating in sexual encounters and sexual double standards, and economic dependencies. In the conclusions, we consider how HIV/AIDS preventive programs can be structured to be gender-sensitive and empowering in Iran.

The learning environment has a significant role in determining nursing students' academic achievements and course satisfaction. Creating a proper educational environment is therefore necessary for improving the quality of teaching and learning, and for delivering competent graduates to society. The present study was conducted to explore teachers' and postgraduate nursing students' experience of the educational environment in Iran. This qualitative study uses an inductive approach and conventional content analysis. Data were collected through semi-structured face-to-face interviews with seven PhD students, seven faculty members (directors) and two focus groups comprising of fourteen master's students in total, selected from three major universities in Tehran, Iran. Seven subcategories were extracted from the data, including the organizational context, interactive climate, teachers' competency, student appreciation, research centeredness, educational guidance and professionalism. The educational environment of postgraduate nursing programs in Iran encompasses different dimensions that can serve as both key points for educational environment evaluators and as guidelines for officials at different levels, to modify the weaknesses and improve the strengths of the system.

The application of DPSIR in Restoring Urban Rivers (Case Study: Darakeh and Farahzad River Restoration, Tehran-Iran) Seyed Oveis Torabi ، Deonna Forman Asgharzadeh , Sadaf Safaai3 Urban river ecosystems, depending on their form, may serve the sprightliness of a city as a beating heart, breathing lungs or main vessels. In other words, sustaining the ecosystem of an urban river and its riparian land can lead to enhancing life quality indices in a city. The Concept of river ecosystem restoration, born out of sustainable development, underpins restoring the health of an urban environment that circles around its river ecosystem. Darakeh and Farahzad are two connecting rivers that originate from the steep, large valleys of Alborz Mountains and flow a total 60km route through the densely populated city of Tehran. Their original basin was 220 km2; however, it has been tremendously altered during the past 50 years. Alongside with urban development and landuse changes, a large flood deviation canal has detached the northern and southern parts of the basin. In addition, river valleys have suffered from land degradation, occurring at the same time severe damages to the river and its riparian ecosystem. In this study, a novel application of DPSIR framework in urban river restoration is introduced. For restoring an ecosystem in a sustainable manner, it is necessary to identify and analyze the social and economic drivers (D) that provide the root cause of ecosystem damages; their consequent pressures directly harming the river and land (P); the degraded state of land and river ecosystem (S) and its impacts on the environment (I). Such approach will enable a precise selection of interrelated technical, economic, social and environmental actions. Thorough multidisciplinary study of Tehran's recent 400 years history revealed that three factors of "safety against flood", "urbanization" and "land commodity" were the main drivers triggering unsustainable development of Tehran, leading to numerous damages of Darakeh and Farahzad Rivers. Accordingly, pressures (P), degraded state (S) and its impacts (I) were determined. Eventually, restoration actions were extracted as appropriate responses (R) to drivers, pressures, state and impacts. Regarding the planning timeline, short-term actions correspond to impacts, mid-term actions address the pressure and state factors and finally, long-term actions comply with the drivers. The application of DPSIR proved as a successful approach to holistic, comprehensive and systematic interpretation of the complicated issues for restoration of Darakeh and Farahzad rivers.

Great earthquakes cause huge damages to human life. Street networks vulnerability makes the rescue operation to encounter serious difficulties especially at the first 72 hours after the incident. Today, physical expansion and high density of great cities, due to narrow access roads, large distance from medical care centers and location at areas with high seismic risk, will lead to a perilous and unpredictable situation in case of the earthquake. Zone # 6 of Tehran, with 229,980 population (3.6% of city population) and 20 km2 area (3.2% of city area), is one of the main municipal zones of Tehran (Iran center of statistics, 2006). Major land-uses, like ministries, embassies, universities, general hospitals and medical centers, big financial firms and so on, manifest the high importance of this region on local and national scale. In this paper, by employing indexes such as access to medical centers, street inclusion, building and population density, land-use, PGA and building quality, vulnerability degree of street networks in zone #6 against the earthquake is calculated through overlaying maps and data in combination with IHWP method and GIS. This article concludes that buildings alongside the streets with high population and building density, low building quality, far to rescue centers and high level of inclusion represent high rate of vulnerability, compared with other buildings. Also, by moving on from north to south of the zone, the vulnerability increases. Likewise, highways and streets with substantial width and low building and population density hold little values of vulnerability.

Studies on the trend of air pollution in Tehran as one of the most polluted metropolis in the world are scant, and today Tehran is known for its high levels of air pollution. In this study, the trend of air pollution concentration was evaluated over the past 10 years (2004-2015). The data were collected from 22 stations of the Air Quality Control Company. Daily concentrations of CO, NO2, SO2, O3, PM10 were analyzed using SPSS 16 based on the statistical method, repeated measures, and intra-group test to determine the pattern of each pollutant changes. As a result of the 22 air pollution monitoring stations, NO2 and SO2 concentrations have been increasing over the period of 10 years. The highest anomaly is related to SO2. The CO concentrations represent a descending pattern over the period, although there was a slight increase in 2013 and 2014. The ozone concentrations declined in the following years. The average concentration of PM10 has been rising during the period. Also we evaluated changes of each pollutant in different months and calculated the number of clean, healthy, unhealthy days for sensitive, unhealthy, very unhealthy, and dangerous groups. The study findings illustrated the necessity for larger investment in air pollution abatement. Over ally, trends have been progressed to worsening, the number of healthy days has been declined and the number of unhealthy days has been increased in recent years.

We studied the shear wave velocity structure and radial anisotropy beneath the Tehran basin by analyzing the Rayleigh wave and Love wave empirical Green's functions obtained from cross-correlation of seismic ambient noise. Approximately 199 inter-station Rayleigh and Love wave empirical Green's functions with sufficient signal-to-noise ratios extracted from 30 stations with various sensor types were used for phase velocity dispersion analysis of periods ranging from 1 to 7 s using an image transformation analysis technique. Dispersion curves extracted from the phase velocity maps were inverted based on non-linear damped least squares inversion method to obtain a quasi-3D model of crustal shear wave velocities. The data used in this study provide an unprecedented opportunity to resolve the spatial distribution of radial anisotropy within the uppermost crust beneath the Tehran basin. The quasi-3D shear wave velocity model obtained in this analysis delineates several distinct low- and high-velocity zones that are generally separated by geological boundaries. High-shear-velocity zones are located primarily around the mountain ranges and extend to depths of 2.0 km, while the low-shear-velocity zone is located near regions with sedimentary layers. In the shallow subsurface, our results indicate strong radial anisotropy with negative magnitude (VSV > VSH) primarily associated with thick sedimentary deposits, reflecting vertical alignment of cracks. With increasing depth, the magnitude of the radial anisotropy shifts from predominantly negative (less than -10%) to predominantly positive (greater than 5%). Our results show a distinct change in radial anisotropy between the uppermost sedimentary layer and the bedrock.

Background: Service quality is perceived as an important factor for developing patient’s loyalty. The aim of this study was to determine the hospital service quality from the patients’ viewpoints and the relative importance of quality dimensions in predicting the patient’s loyalty. Methods: A cross-sectional study was conducted in 2010. The study sample was composed of 943 patients selected from eight private general hospitals in Tehran. The survey instrument was a questionnaire included 24 items about the service quality and 3 items about the patient’s loyalty. Exploratory factor analysis was employed to extracting the dimensions of service quality. Also, regression analysis was performed to determining the relative importance of the service quality dimensions in predicting the patient’s loyalty. Result: The mean score of service quality and patient’s loyalty was 3.99 and 4.16 out of 5, respectively. About 29% of the loyalty variance was explained by the service quality dimensions. Four quality dimensions (Costing, Process Quality, Interaction Quality and Environment Quality) were found to be key determinants of the patient’s loyalty in the private hospitals of Tehran. Conclusion: The patients’ experience in relation to the private hospitals’ services has strong impact on the outcome variables like willingness to return to the same hospital and reuse its services or recommend them to others. The relationship between the service quality and patient’s loyalty proves the strategic importance of improving the service quality for dragging and retaining patients and expanding the market share.

Haematophagous females of some phlebotomine sandflies are the only natural vectors of Leishmania species, the causative agents of leishmaniasis in many parts of the tropics and subtropics, including Iran. We report the presence of Phlebotomus (Larroussius) major and Phlebotomus (Adlerius) halepensis in Tonekabon (Mazanderan Province) and Phlebotomus (Larroussius) tobbi in Pakdasht (Tehran Province). It is the first report of these species, known as potential vectors of zoonotic visceral leishmaniasis in Iran, are identified in these areas. In 2006-2007 individual wild-caught sandflies were characterized by both morphological features and sequence analysis of their mitochondrial genes (Cytochrome b). The analyses were based on a fragment of 494 bp at the 3' end of the Cyt b gene (Cyt b 3' fragment) and a fragment of 382 bp CB3 at the 5' end of the Cyt b gene (Cyt b 5' fragment). We also analysed the Cyt b Long fragment, which is located on the last 717 bp of the Cyt b gene, followed by 20 bp of intergenic spacer and the transfer RNA ser(TCN) gene. Twenty-seven P. halepensis and four P. major from Dohezar, Tonekabon, Mazanderan province and 8 P. tobbi from Packdasht, Tehran Province were identified by morphological and molecular characters. Cyt b 5' and Cyt b 3' fragment sequences were obtained from 15 and 9 flies, respectively. Cyt b long fragment sequences were obtained from 8 out of 27 P. halepensis. Parsimony analyses (using heuristic searches) of the DNA sequences of Cyt b always showed monophyletic clades of subgenera and each species did form a monophyletic group.

Background: Patient safety culture plays an important role in healthcare systems, especially in chemotherapy and oncology departments (CODs), and its assessment can help to improve quality of services and hospital care. Objective: This study aimed to evaluate and compare items and dimensions of patient safety culture in the CODs of selected teaching hospitals of Iran and Tehran University of Medical Sciences. Materials and Methods: This descriptive-analytical cross-sectional survey was conducted during a six-month period on 270 people from chemotherapy and oncology departments selected through a cluster sampling method. All participants answered the standard questionnaire for “Hospital Survey of Patient Safety Culture” (HSOPSC). Statistical analyses were performed using SPSS/18 software. Results: The average score for patient safety culture was three for the majority of the studied CODs. Statistically significant differences were observed for supervisor actions, teamwork within various units, feedback and communications about errors, and the level of hospital management support. (p<0.05). Relationships between studied hospitals and patient safety culture were not statistically significant (p>0.05). Conclusion: Our results showed that the overall status of patient safety culture is not good in the studied CODs. In particular, teamwork across different units and organizational learning with continuous improvement were the only two properly operating items among 12 dimensions of patient safety culture. Therefore, systematic interventions are strongly required to promote communication. PMID:29072411

Use of unsealed radiopharmaceuticals in Iran's nuclear medicine centers has expanded rapidly in the last decade. As part of a nationwide survey, this study was undertaken to estimate the radiation risk due to the diagnostic nuclear medicine procedures performed in Tehran in 1999-2003. During the five years of the study, the data of 101,540 yearly examinations of diagnostic nuclear medicine were obtained for 34 (out of 40) active nuclear medicine centers in Tehran. The patients studied were aged 1 y, 5 y, 10 y, 15 y, and adults (>15 y). Compared to an earlier investigation in 1989 (which was published in 1995), striking changes were found to be occurring in the trends of nuclear medicine in Tehran in a matter of a decade. The frequency of cardiac examinations increased from less than 1% in 1989 to 43.2% (mean of 5 y) in 2003; thyroid examinations, with the relative frequency of higher than 80% in 1989, decreased to 26.7% in the current investigation (averaged for 2001); and the number of overall examinations per 1,000 population of Tehran increased from 1.9 in 1989 to 8.8 in this study (about fourfold). The decrease in relative frequency of thyroid examinations could be attributed to the lower referral policy (mainly by specialists), decreased incidence of goiter due to implementation of programs for iodine enrichment diets, introduction of fine needle aspiration (FNA), and sonography techniques for diagnosis of thyroid disease. The large increase in relative frequency of cardiac examinations could be due to the increase in the number of single photon emission computerized tomography (SPECT) systems in recent years as compared to 1989 in Tehran. The collective effective dose increased from 400 (person-Sv) in 1999 to 529 (person-Sv) in 2003, and the effective dose per capita increased from 34.80 μSv in 1999 to 44.06 μSv in 2003 (average, 35.60 μSv).

Considering the scarcity of skilled workers in the health sector, the appropriate distribution of human resources in this sector is very important for improving people's health. Having information about the degree of equality in the distribution of health human resources and their time trends is necessary for better planning and efficient use of these resources. The aim of this study was to determine the trend of inequality in the allocation of human resources in the health sector in Tehran between 2007 and 2013. This cross-sectional study was conducted in Tehran Province in Iran. The inequality in the distribution of human resources (specialists, general practitioners, pharmacists, paramedics, dentists, nurses and community health workers (Behvarz)) in 10 cities in Tehran Province was investigated using the Gini coefficient and the dissimilarity index. The time trend of inequality was examined by regression analysis. The required data were collected from the statistical yearbook of the Iran Statistics Center (ISC). The highest value of the Gini coefficient (GC) was related to nurses (GC = 0.291) in 2007. The highest value of the Gini coefficient was related to nurses and Behvarzs in 2008 and 2009, respectively. The distribution of specialists had the highest inequality in 2010 (GC = 0.298), 2011 (GC = 0.300) and 2013 (GC = 0.316). General practitioners had the lowest Gini coefficient for 2007, 2008 and 2012. Nurses for 2009 and Behvarzs for 2010, 2011 and 2013 had the lowest value of Gini coefficient. The dissimilarity indexes for specialists and general practitioners were 26.64 and 8.72 in 2013, respectively. The means of this index for included resources were 31.35, 18.27, 16.91, 22.32, 15.82, 26.74, and 24.33, respectively. The time trend analysis showed that the coefficient of time was positive for all of the human resources, except Behvarzes, and only the coefficient of general practitioners was statistically significant ( p<0.01). Over time, inequalities in the distribution of resources in the health sector have been increasing. By developing the private sector and considering the trend of this sector to operate in the more developed regions, health policy makers should continually evaluate the distribution of human resources, and they should arrange a specific plan for the allocation of human resources in the health sector.

The prevalence of obesity is increasing in Iran. Previous studies showed mixed results in relation to association between socioeconomic status and obesity in the country. The current study aimed to examine educational inequalities among adults in Tehran in 2011. Data on 90,435 persons 18 years and older from Urban Health Equity Assessment and Response Tool (Urban HEART-2) were analyzed. The Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were used for assessing educational inequalities in obesity. These measures were quantified using generalized linear models for the binomial family adjusted for sex and age. Subgroup analysis was conducted across sex, age groups and the 22 districts of Tehran. Both SII and RII showed substantial educational inequalities in obesity in favour of more educated adults [RII and SII (95% CI were equal to 2.91 (2.71-3.11) and 0.12 (0.12-0.13)), respectively]. These educational inequalities were persistent even after adjusting for employment, marital status and smoking. Subgroup analysis revealed that educational inequalities were more profound among women. While among men educational inequalities were generally increasing with age, an inverse trend was observed among women. Educational inequalities were observed within all 22 districts of Tehran and generally there were no statistically significant differences between districts. An inverse association between education and obesity was observed in the current study. To decrease educational inequalities in Tehran, priority should be given to younger women and older men. Further analyses are needed to explain these inequalities. Copyright © 2015 Asia Oceania Association for the Study of Obesity. Published by Elsevier Ltd. All rights reserved.

The aim of this study was to assess leisure time physical activity and its determinants among adults in Tehran. This cross-sectional study comprised adults (n = 7285), aged 20 years and older. The subjects were participants of the Tehran Lipid and Glucose Study between 2002 and 2004. Information on the number of days spent on different activities during a week and the time devoted to each activity on a typical day was recorded. In addition, each activity, weighted by its relative intensity, was referred to as a metabolic equivalent. The prevalence of inactivity was 69.8% (95% CI: 68.7-70.8) in the whole population and 30.2% (95% CI: 27.2-33.1%) of men and 30.3% (95% CI: 27.7-32.8%) of women were considered as active. Leisure time physical activity less than 30 min/week was scored in 1590 (50.6%) men and 1803 (43.5%) women. The most frequent leisure time physical activity performed by men (96.1%) and women (95.2%) was walking. A negative association was observed in men between leisure time physical activity and increased work hours, older age, more cigarette smoking and higher body mass index (69.8% were overweight and 75.3% were obese; P < 0.05). Leisure time physical activity was more likely to be associated with high educational levels in men. In addition, there was a statistically significant relationship between physical inactivity and occupation in both men and women. The prevalence of physical inactivity among adults in Tehran was high. Leisure time physical inactivity was more likely to be associated with older age, more cigarette smoking, more working hours, and higher body mass index. Public health efforts are needed to improve people's participation in physical activities in Iran.

Organizational learning has been identified as necessary for different organizations to improve their performance in the changing and competitive environment. The main purpose of this research was to specify the learning organization profile of educational and health centers of Tehran and Qazvin Universities of Medical Sciences in Iran. The present research was conducted using a cross-sectional method in the academic year of 2013-2014. A staff of 530 from educational hospitals subordinated to Tehran and Qazvin universities of medical sciences participated in the research. The participants were selected using stratified random sampling. That is to say, a random sample of a proportionate size was selected from each hospital. The instrument for data collection was a Likert-scale questionnaire involving 50 items. The statistical techniques of ANOVA, t-test, Chi-square, correlation coefficients (Pearson and Spearman), and regression were utilized to analyze the data. All of them were performed using the Statistical Package for Social Sciences (SPSS) 16.0 for windows. the results indicated that 449 of participants (84.7%) had a B.S. degree and 78 of them (14.7%) had an M.S. or a Ph.D. degree. Among the fivefold dimensions of "Learning Organization" model (Learning, Organization, People, Knowledge, and Technology) in comparison of the two universities, the "people" dimension was the highest-rated dimension with the mean rating of 25.71±8.36 and the "learning" dimension was the lowest-rated dimension with the mean of 25.35±8.04. Comparison between the two universities yielded the result that educational hospitals in Tehran University of medical sciences with the rating of 126.56 had a more complete profile than that of educational hospitals in Qazvin university of medical sciences with the rating of 122.23. The hospitals of the two above-mentioned universities were, to a great extent, far from the characteristics of Learning Organization. In light of the massive mission of these centers to maintain and improve the community health and to train the skilled labor force, the centers should embark on updating the data and institutionalizing learning. Furthermore, to modify staff's behavior and performance and to achieve their goals, they should accentuate the importance of acquiring, creating, and transferring knowledge.

Anthropometric studies in Afghan immigrants in Iran have not been yet performed; therefore the aim of the present study is to identify Body Mass Index (BMI) in a sample of Afghan immigrant children in Iran during the year 2005. In this cross-sectional study 606 Afghan children aged between 6-14 years have been randomly selected within Shahriar County of Tehran Province of Iran and their weight and height have been measured. Then, using BMI formula BMI = Weight (kg)/Height (m2) their BMI was calculated and based on CDC (Centers for Disease and Prevention Control) indices, children were categorized as: under weight, normal and obese. Results of this study showed that 97 cases (16%) had low weight whereas, 429 cases (81.2%) had normal weight and 17 cases (2.8%) had over weight. More percentage of girls had lower weight than the boys (15.2 versus 16.9%), Afghan children who were born in Iran had also lower weight (17.3%) than those who were born in Afghanistan (15.2%) and third and upper birth order children had lower weight compared to first and second birth order (17 versus 15.3%). However, none of these differences were statistically significant. The researchers suggest that due to high incidence of malnutrition in Afghan immigrant children in Iran interventional and educational programs are needed in order to improve their level of health and nutritional status.

Iranian crack is a new form of narcotic substance that has found widespread prevalence in Iran in the past years. Crack only nominally resembles crack cocaine as it is widely different in its clinical signs. Thus the present study aims to quantify the chemical combination of this drug. The samples included 18 specimen of Crack collected from different zones of Tehran, Iran. All specimens were in the form of inodorous cream solid powdery substance. TLC and HPLC methods were used to perform semi-quantitative and quantitative analysis of the components, respectively. The TLC analysis showed no cocaine compound in the specimens while they all revealed to contain heroin, codeine, morphine and caffeine. All but two specimens contained thebaine. None of the specimens contained amphetamine, benzodiazepines, tricyclic antidepressants, aspirin, barbiturates, tramadol and buprenorphine. Acetaminophen was found in four specimens. HPLC revealed heroin to be the foundation substance in all specimens and most of them contained a significant amount of acetylcodeine. The present analysis of the chemical combination of Crack showed that this substance is a heroin-based narcotic which is basically different from the cocaine-based crack used in Western countries. Studies like the present one at different time points, especially when abnormal clinical signs are detected, can reveal the chemical combination of the target substance and contribute to the clinical management of its acute or chronic poisoning.

A monitoring program in boundary areas of a country is an appropriate way to indicate the level of public exposure. In this research, gamma background radiation was measured using TL dosimeters at 12 boundary areas as well as in the capital city of Iran during the period 2010 to 2011. The measurements were carried out in semi-annual time intervals from January to June and July to December in each year. The maximum average dose equivalent value measured was approximately 70 μSv/month for Tehran city. Also, the average dose values obtained were less than 40 μSv/month for all the cities located at the sea level except that of high level natural radiation area of Ramsar, and more than 55 μSv/month for the higher elevation cities. The public exposure due to ambient gamma dose equivalent in Iran is within the levels reported by UNSCEAR. Copyright © 2015 Elsevier Ltd. All rights reserved.

In this paper, two satellite images of Tehran, the capital city of Iran, which were taken by TM and ETM+ for years 1988 and 2010 are used as the base information layers to study the changes in urban patterns of this metropolis. The patterns of urban growth for the city of Tehran are extracted in a period of twelve years using cellular automata setting the logistic regression functions as transition functions. Furthermore, the weighting coefficients of parameters affecting the urban growth, i.e. distance from urban centers, distance from rural centers, distance from agricultural centers, and neighborhood effects were selected using PSO. In order to evaluate the results of the prediction, the percent correct match index is calculated. According to the results, by combining optimization techniques with cellular automata model, the urban growth patterns can be predicted with accuracy up to 75 %.

Professional behavior is first learned at the university. One of the necessary considerations in maintaining the professional environment of the university is establishing a set of codes for the behavior of physicians and medical students. This paper describes the process of developing the professional code of conduct in Tehran University of Medical Sciences, Tehran, Iran. A review of Iranian and international literature was performed to develop the first draft of the guideline. In sessions of group discussion by the authors, the articles of the draft were evaluated for relevancy, clarity, and lack of repetition. The draft was sent for evaluation to all participants, including the medical faculty members, residents, and medical students, four times and necessary corrections were made according to the comments received. The final guideline included 76 behavior codes in 6 categories, including altruism, honor and integrity, responsibility, respect, justice, and excellence. The codes of the guideline cover the physicians' commitments in the physician-patient, physician-colleague, and instructor-student relationships in order to improve the quality of the services. The Islamic and Iranian culture were taken into consideration in developing the guideline. Accordance with the administrative and educational conditions of the universities was ensured in developing the guideline and its acceptance was ensured through extensive surveys. Thus, it is expected that this guideline will be very effective in enhancing professional commitment in medical universities.

Primary health care physicians (PHCPs) are the first in the clinic to detect and help victims of intimate partner violence (IPV). Therefore, their attitude and practice toward domestic violence (DV) are important to manage this problem. The aim of current study was to compare the behavior and attitude of PHCPs about DV versus other health risk factors in Tehran, Iran. A convenience sample of 220 PHCPs was evaluated. The study was carried out in April 2012. Two self-administered questionnaires were used to identify physicians' beliefs and behaviors on screening and intervention of DV and other health risk factors. All analyses were performed using SPSS version 18.0 (SPSS, Inc. Chicago, IL). One hundred and ninety eight questionnaires were analyzed. PHCPs' mean age was 39.06 (±7.5) years. Participants were just reported 10% screening of regular patients for DV compared with 29% to 48% for other health risk factors. Mean age of PHCPs was not associated with their approach toward the DV. Compared to male physicians, females spared more time for DV victims. Major of physicians (96%) believed that DV is not a private problem and is something that needs to be addressed cautiously. The results of this study indicated that DV screening occurs less than that of other health risk factors. Attitude of majority of PHCPs was positive for addressing this problem.

Clinical Governance (CG) program has been raised in Iran in order to improve the quality of clinical care. The purpose of this study is to investigate the awareness of clinical governance program among clinical staff working in selected teaching hospitals in Tehran, Iran. To investigate the CG awareness, a cross-sectional survey was conducted among 345 clinical staff working in 20 selected public hospitals in Tehran. Data were gathered using the standardized clinical governance awareness questionnaire. Descriptive statistics were used to analyze the data. The results showed that the level of staff awareness about the concept of CG was low. They perceived continuous quality improvement, responsibility, medical errors reduction and patient safety as the main concepts of the CG framework. Reaching agreement of standards concepts among staff and positive changes in attitudes were considered as two most observed changes. The main perceived barriers to the implementation of clinical governance included lack of proper management and leadership, lack of full support, inappropriate organizational culture, lack of knowledge, poor communication system and insufficient training. The concepts and goals of clinical governance have not been effectively conveyed to the staff and despite its implementation in the hospitals, there has been low clinical governance awareness among the staff. Clinical Governance must be implemented through comprehensive management support and participation of all staff and health professionals at both hospital and policy making level.

A field sampling campaign was implemented to evaluate the variation in air pollutants levels near a highway in Tehran, Iran (Hemmat highway). The field measurements were used to estimate road link-based emission factors for average vehicle fleet. These factors were compared with results of an in tunnel measurement campaign (in Resalat tunnel). Roadside and in-tunnel measurements of carbon monoxide (CO) and size-fractionated particulate matter (PM) were conducted during the field campaign. The concentration gradient diagrams showed exponential decay, which represented a substantial decay, more than 50-80%, in air pollutants level in a distance between 100 and 150meters (m) of the highway. The changes in particle size distribution by distancing from highway were also captured and evaluated. The results showed particle size distribution shifted to larger size particles by distancing from highway. The empirical emission factors were obtained by using the roadside and in tunnel measurements with a hypothetical box model, floating machine model, CALINE4, CT-EMFAC or COPERT. Average CO emission factors were estimated to be in a range of 4 to 12g/km, and those of PM10 were 0.1 to 0.2g/km, depending on traffic conditions. Variations of these emission factors under real working condition with speeds were determined. Copyright © 2015 Elsevier B.V. All rights reserved.

Shigellosis is a considerable infectious disease with high morbidity and mortality among children worldwide. In this survey the prevalence of four important virulence genes including ial, ipaH, set1A, and set1B were investigated among Shigella strains and the related gene profiles identified in the present investigation, stool specimens were collected from children who were referred to two hospitals in Tehran, Iran. The samples were collected during 3 years (2008-2010) from children who were suspected to shigellosis. Shigella spp. were identified throughout microbiological and serological tests and then subjected to PCR for virulotyping. Shigella sonnei was ranking first (65.5%) followed by Shigella flexneri (25.9%), Shigella boydii (6.9%), and Shigella dysenteriae (1.7%). The ial gene was the most frequent virulence gene among isolated bacterial strains and was followed by ipaH, set1B, and set1A. S. flexneri possessed all of the studied virulence genes (ial 65.51%, ipaH 58.62%, set1A 12.07%, and set1B 22.41%). Moreover, the pattern of virulence gene profiles including ial, ial-ipaH, ial-ipaH-set1B, and ial-ipaH-set1B-set1A was identified for isolated Shigella spp. strains. The pattern of virulence genes is changed in isolated strains of Shigella in this study. So, the ial gene is placed first and the ipaH in second.

Because of high psychological burden and considerable costs of in-vitro fertilization, it is greatly important to identify all factors that may influence its results. In this study, general anesthesia and spinal analgesia used for oocyte retrieval were compared in terms of success in treating infertility among couples who had undergone in-vitro fertilization at an infertility center in Tehran, Iran. This cohort study that was based on analysis of patient records at Mirza Kochak Khan Hospital, Tehran University of Medical Sciences, in 2008-2009. In this study, the status of chemical pregnancy among those who experienced general anesthesia or spinal anesthesia for in-vitro fertilization for the first time were compared, and the possible effects of clinical and laboratory factors using logistic regression models were considered. Considering the number of transferred embryos, underlying cause of infertility and fetus grade, it was found that practicing spinal anesthesia is significantly related to increased chance of chemical pregnancy (adjusted Odds Ratio=2.07; 95% CI: 1.02,4.20; p=0.043). According to analysis of recorded data in an infertility treatment center in Iran, it is recommended to use spinal anesthesia instead of general anesthesia for oocyte retrieval to achieve successful in-vitro fertilization outcome. This can be studied and investigated further via a proper multicentric study in the country.

The main objectives of this study were (1) investigation of the temporal variations of ambient fine particulate matter (PM 2.5 ) and ground level ozone (O 3 ) concentrations in Tehran megacity, the capital and most populous city in Iran, over a 10-year period from 2006 to 2015, and (2) estimation of their long-term health effects including all-cause and cause-specific mortality. For the first goal, the data of PM 2.5 and O 3 concentrations, measured at 21 regulatory monitoring network stations in Tehran, were obtained and the temporal trends were investigated. The health impact assessment of PM 2.5 and O 3 was performed using the World Health Organization (WHO) AirQ+ software updated in 2016 by WHO European Centre for Environment and Health. Local baseline incidences in Tehran level were used to better reveal the health effects associated with PM 2.5 and O 3 . Our study showed that over 2006-2015, annual mean concentrations of PM 2.5 and O 3 varied from 24.7 to 38.8 μg m -3 and 35.4 to 76.0 μg m -3 , respectively, and were significantly declining in the recent 6 years (2010-2015) for PM 2.5 and 8 years (2008-2015) for O 3 . However, Tehran citizens were exposed to concentrations of annual PM 2.5 exceeding the WHO air quality guideline (WHO AQG) (10 μg m -3 ), U.S. EPA and Iranian standard levels (12 μg m -3 ) during entire study period. We estimated that long-term exposure to ambient PM 2.5 contributed to between 24.5% and 36.2% of mortality from cerebrovascular disease (stroke), 19.8% and 24.1% from ischemic heart disease (IHD), 13.6% and 19.2% from lung cancer (LC), 10.7% and 15.3% from chronic obstructive pulmonary disease (COPD), 15.0% and 25.2% from acute lower respiratory infection (ALRI), and 7.6% and 11.3% from all-cause annual mortality in the time period. We further estimated that deaths from IHD accounted for most of mortality attributable to long-term exposure to PM 2.5 . The years of life lost (YLL) attributable to PM 2.5 was estimated to vary from 67,970 to 106,706 during the study period. In addition, long-term exposure to O 3 was estimated to be responsible for 0.9% to 2.3% of mortality from respiratory diseases. Overall, long-term exposure to ambient PM 2.5 and O 3 contributed substantially to mortality in Tehran megacity. Air pollution is a modifiable risk factor. Appropriate sustainable control policies are recommended to protect public health. Copyright © 2018 Elsevier Ltd. All rights reserved.

Women may bear the brunt of domestic violence, but children are also inflicted by the consequences of violence between their parents. We sought to evaluate the lifetime prevalence of exposure to physical violence between parents among some senior secondary school students in Tehran. The study was conducted on senior secondary school students in all 19 educational districts of the Iranian capital, Tehran, in the academic year of 2005-06 using a multi-stage sampling. Data were collected via a self-administered questionnaire. A total of 1,495 students participated in this survey, with the prevalence estimated at 22.8%. More than half of the subjects had witnessed domestic violence between their parents; the prevalence of exposure among the girls was twice that among the boys. The most frequent act of violence was beating the partner with bare hands and the perpetrators of the violent acts were predominantly the fathers. Exposure was long-lasting; and in those with more than one exposure, the mean duration of exposure was 5.1 years. The most prevalent rates of exposure to domestic violence came from Educational Districts 15 and 10. The fact that a considerable portion of the teenagers in the present study had witnessed physical violence between their parents bears testimony to the high frequency of this form of violence in Tehran households. It is noteworthy that the socio-economic status of the families and parental divorce and estrangement increased the likelihood of exposure to domestic violence in our series.

Evaluation of intra-city roads in terms of environmental factors of motor vehicle injuries can help us to better identify these factors and the share of each of the factors in injuries. Therefore, this study was conducted to determine the high injury areas and the risk factors of motor vehicle crashes resulting in injury and death in Tehran, the capital city of Iran, from November 2011 through February 2012. In this cross sectional study, the locations of the motor vehicle injuries resulting in injuries and deaths were obtained from police stations in Tehran. The coordinates of the injuries locations were extracted and entered into the Arc-GIS software to overlay the different layers of geographical data and extract the risk map. A total of 4257 motor vehicle injuries were evaluated in this study. Forty-two injuries (1%) resulted in death and 4215 injuries (99%) resulted in injury. The traffic districts 5 and 21 had the highest frequency of injuries resulting in death. The type of the motor vehicle resulting in injury or death was motorcycle in 2330 injuries (54.73%). The frequency of traffic injuries is more in the west and northwest areas of Tehran, and it is caused more by motorcycles in terms of traffic and motor injuries resulting in injury and death. It is useful to conduct more studies to better identify these factors considering their importance in traffic injuries.

The quality of services plays a primary role in achieving patient satisfaction. The main purpose of this study was to explore the effect of outpatient service quality on patient satisfaction in teaching hospitals in Iran. this cross-sectional study was conducted in 2014. The study sample included 500 patients were selected with systematic random method from the outpatient departments (clinics) of four teaching hospitals in Tehran. The survey instrument was a questionnaire consisted of 44 items, which were confirmed its reliability and validity. The data were analyzed by using descriptive statistics, Pearson's correlation, and multivariate regression methods with the SPSS.18 software. According to the findings of this study, the majority of patients had a positive experience in the outpatient departments of the teaching hospitals and thus evaluated the services as good. Perceived service costs, physician consultation, physical environment, and information to patient were found to be the most important determinants of outpatient satisfaction. The results suggest that improving the quality of consultation, providing information to the patients during examination and consultation, creating value for patients by reducing costs or improving service quality, and enhancing the physical environment quality of the clinic can be regarded as effective strategies for the management of teaching hospitals toward increasing outpatient satisfaction.

It has been five years since some 60 political activists; many scholars and university professors among them, with alleged links to the so-called ``nationalist-religious'' group and the Freedom Movement of Iran (FMI) were arrested in March and April 2001 on a series of charges including plotting to topple the Islamic establishment in Iran. Almost all of those detained were later released on bail and stood trials before different branches of the Tehran Revolutionary Court, and court of appeals. All sessions and hearings were held behind closed doors! Final verdicts have been gradually delivered, but the judiciary refuses to enforce the sentences, drop the charges, or return the bails. The whole case has been turned into a Sword of Damocles held over the heads of all political activists who happen to be critical of the system.

Despite the remarkable burden of dysphagia, appropriate multidisciplinary management is lacking in Iran and patients are often deprived of effective treatments. Obtaining a full understanding of knowledge, attitude and practice (KAP) of healthcare providers is necessary to determine the gaps in improvement of the quality of care for dysphagic patients. A questionnaire was designed covering demographic information and the parameters of KAP. Face and content validity were determined. Test-retest reliability confirmed that the questionnaire scores are stable over time (r = 0.77, p value < 0.01). Participants were healthcare providers employed in university-affiliated hospitals in three major cities of Iran; Tehran, Shiraz and Mashhad. In total, 312 healthcare professionals completed our survey. The majority (96.8%) were familiar with the term "dysphagia or swallowing disorders". Most of the participants believed their profession (88.5%), as well as other disciplines (92.3%) can play an important role in the management of dysphagia; and this problem should be recognized in a multidisciplinary manner (96.2%). Also, 60.9% had encountered a patient with dysphagia. 52.2% had used at least one assessment method, while 49.9% had applied at least one treatment method. However, very few participants were familiar with a standard test for screening and assessment of dysphagia (11.9%). 74.7% were willing to participate in a workshop on dysphagia. As the main pitfalls of care lie in diagnosis and treatment expertise, the policy of hospitals should prioritize educating and updating the skills of healthcare professionals, encourage multidisciplinary teamwork, establishing clear guidelines and facilitate access to advanced tools.

Given the hazardous nature of the work in steel factories and that the staff has to deal with hazardous equipment and machines, improper sleep quality and drowsiness among the works tackles performance and boosts rate of job accidents. This study is aimed to survey the quality of sleep and sleepiness status and the pertinent factors among the workers in a rolling mill and a steel production company in Tehran, Iran. In a Cross-Sectional study 2011, 180 workers were selected randomly from a rolling mill and a steel production company in Tehran. A questionnaire was designed to collect demographic data and variables of work condition. Pitersborg's sleep quality questionnaire was used to survey quality and problems of Participants' sleep. Epworth Sleepiness questionnaire was used to deals with sleepiness during work, studying, watching TV, or during time spent in public. Average score of sleep quality for the fixed shift staff and changing shift staff were 7.5±2.82 and 8.49±2.95 respectively. Surveys of sleep quality for the two groups of the participants based on T-test showed a significant difference between the two groups so that the changing shift staff group suffered poorer sleep quality (p=0.03). Comparison of average drowsiness scores between the two groups of participants based on Mann-Whitney test showed no significant difference (p>0.005). Chi square test showed a significant difference between severity of drowsiness and type of working shift (p =0.028 and 0.009). Staff in revolving shifts suffers poor sleep quality comparing with staff with fixed working shift. Moreover, type of working shift greatly affects severity of drowsiness as staff at different work shift experienced different level of sleepiness. It is essential to survey sleep disorder of the staff in the industry and pay more emphasis on sleep disorder epidemic in other fields of industry.

Iran's experience with surrogate motherhood: an Islamic view and ethical concerns.

PubMed

Aramesh, K

2009-05-01

Gestational surrogacy as a treatment for infertility is being practised in some well-known medical institutions in Tehran and some other cities in Iran. While the majority of Muslims in the world are Sunni, the majority of Iranians are Shiite. Most Sunni scholars do not permit surrogate motherhood, since it involves introducing the sperm of a man into the uterus of a woman to whom he is not married. Most Shiite scholars, however, have issued jurisprudential decrees (fatwas) that allow surrogate motherhood as a treatment for infertility, albeit only for legal couples. They regard this practice as transferring an embryo or fetus from one womb to another, which is not forbidden in Shiite jurisprudence. Nevertheless, there are some controversies concerning some issues such as kinship and inheritance. The main ethical concern of Iran's experience with gestational surrogacy is the monetary relation between the intended couple and the surrogate mother. While monetary remuneration is practised in Iran and allowed by religious authorities, it seems to suffer from ethical problems. This article proposes that this kind of monetary relation should be modified and limited to reimbursement of normal costs. Such modification requires new legislation and religious decrees.

Cholera is considered a key indicator of social development but still is reported in various cities of Iran. The present study aimed to analyze the available information regarding cholera outbreaks since 2010 in Iran. All cases reported to the Center for Disease Control and Prevention of Ministry of Health and Education who had been confirmed as cholera cases by the Health Reference Laboratory, were entered into this study since 2010. A specific spreadsheet was designed to ensure the safe keeping of the patient records. A total of 1522 patients were clinically diagnosed as cholera with laboratory confirmation over the study period. Cholera was detected in 26 Provinces and 115 cities during this period. Mean age of the patients was 35.1±17, both the Inaba and Ogawa strains were isolated. The highest mortality and the morbidity rate was 1.98% in 2013. The most cholera prevalent provinces in order of frequency were Baluchistan, Alborz, Gilan, Golestan and Qom, as well as Tehran. Inaba serotype was the most common cause of mortality and morbidity in 2013. These findings indicate significant outbreaks of cholera in some of the provinces of Iran and warrant appropriate treatment and preventive measures.

Extremely Low-Frequency (ELF) electric and magnetic fields belonging to the nonionizing electromagnetic radiation spectrum have a frequency of 50 - 60 Hz. All people are exposed to a complex set of electric and magnetic fields that spread throughout the environment. The current study was carried out to assess people's exposure to an ELF electric field in the Tehran metropolitan area in 2010. The measurement of the electronic fields was performed using an HI-3604 power frequency field strength measurement device. A total number of 2,753 measurements were performed. Afterward, the data obtained were transferred to the base map using Arc View Version 3.2 and Arc Map Version 9.3. Finally, an interpolation method was applied to expand the intensity of the electric field to the entire city. Based on the results obtained, the electric field was divided into three parts with various intensities including 0-5 V m, 5-15 V m, and >15 V m. It should be noted that the status of high voltage transmission lines, electric substations, and specific points including schools and hospitals were also marked on the map. Minimum and maximum electric field intensities were measured tantamount to 0.31 V m and 19.80 V m, respectively. In all measurements, the electric field was much less than the amount provided in the ICNIRP Guide. The results revealed that 141 hospitals and 6,905 schools are situated in an area with electric field intensity equal to 0-5 V m, while 15 hospitals and 95 schools are located in zones of 5-15 V m and more than 15 V m. Examining high voltage transmission lines and electric substations in Tehran and its suburbs suggested that the impact of the lines on the background electric field of the city was low. Accordingly, 0.97 km of Tehran located on the city border adjacent to the high voltage transmission lines have an electric field in the range of 5 to 15 V m. The noted range is much lower than the available standards. In summary, it can be concluded that the public is not exposed to a risky background electric field in metropolitan Tehran. The result of comparing sensitive recipients showed that the schools have a more desirable status than the hospitals. Nonetheless, epidemiologic studies can lead to more understanding of the impact on public health.

The majority of visually impaired people live in developing countries, and since most disorders leading to visual impairment are preventable or curable, their control is a priority in these countries. Considering the complicated epidemiology of visual impairment and the wide variety of factors involved, region specific intervention strategies are required for every community. Therefore, providing appropriate data is one of the first steps in these communities, as it is in Iran. The objectives of this study are to describe the prevalence and causes of visual impairment in the population of Tehran city; the prevalence of refractive errors, lens opacity, ocular hypertension, and color blindness in this population, and also the familial aggregation of refractive errors, lens opacity, ocular hypertension, and color blindness within the study sample. Methods Design Through a population-based, cross-sectional study, a total of 5300 Tehran citizens will be selected from 160 clusters using a stratified cluster random sampling strategy. The eligible people will be enumerated through a door-to-door household survey in the selected clusters and will be invited. All participants will be transferred to a clinic for measurements of uncorrected, best corrected and presenting visual acuity; manifest, subjective and cycloplegic refraction; color vision test; Goldmann applanation tonometry; examination of the external eye, anterior segment, media, and fundus; and an interview about demographic characteristics and history of eye diseases, eye trauma, diabetes mellitus, high blood pressure, and ophthalmologic cares. The study design and eye examination protocol are described. Conclusion We expect that findings from the TES will show the status of visual problems and their causes in the community. This study can highlight the people who should be targeted by visual impairment prevention programs. PMID:12859794

Objectives: Identifying the underlying factors contributing to smoking among teenagers is important in establishing smoking control programs. The present study was designed to identify and compare factors revealed in a preceding qualitative study conducted on 13-15 year-old boys living in two different socio-economic districts in the Northern and Southern parts of Tehran. Methods: Two completely similar case-control studies, each with 200 subjects, were conducted using a snowball sampling. The case and control subjects were matched based on the intimacy relations, i.e. six smokers were recruited in each of the Northern and Southern districts; they were then asked to introduce one of their smoker friends as a case and a non-smoker one as a control. Results: Multi-variable conditional logistic regression revealed that having a smoker father is the single effective factor in the two districts. As for boys living in the Northern (wealthier) part of the city, social capital (OR: 0.59, 95% CI: 0.43-0.81) played a protective role against smoking, whereas quitting home after a quarrel (OR: 15.07, 95% CI: 1.54-147.25), monthly allowance (OR: 2.22, 95% CI: 1.29-3.82) and hyperactivity (OR: 1.69, 95% CI: 2.64-240.45) were associated with a higher risk of becoming a smoker. Conclusions: The studied variables can be classified as personal, familial, and school-level factors. Familial intervention is effective for all the factors which revealed to be influential on the risk of becoming a smoker. It could be concluded that interventions on the family level should be used to prevent the cigarette use in Tehran. PMID:22174960

Food insecurity is defined as the limited or uncertain availability of enough food for permanent active and healthy life. Upper gastrointestinal (GI) cancers (esophagus and stomach) are one of five most common cancers in Iran. This study aimed to determine the association of food insecurity and upper GI cancers in newly diagnosed patients. Case-control study. Overall, 120 patients with upper GI cancers as cases and 120 patients with orthopedic, ear-nose-throat (ENT), and neurologic diseases as controls were recruited from Imam Khomeini Hospital, Tehran, Iran in 2013. The patients were newly diagnosed using endoscopy or imaging or biopsy methods. They were individually matched for age, sex, and residential area. The general and United States Department of Agriculture (USDA) household food security questionnaires were completed. The univariate and multivariate conditional logistic regression tests were applied using the Stata 11SE statistical software. The food insecurity prevalence was 69.2% and 43.3% in cases and controls, respectively. Food insecurity, low economic level and family history of cancer were significantly associated with cancer (P<0.05). Food insecurity was one of the important risk factors for upper GI cancers that health care providers should consider it.

Variation in cancer incidence in geographical locations is due to different lifestyles and risk factors. Diet and socio-economic position (SEP) have been identified as important for the etiology of cancer but patterns are changing and inconsistent. The aim of this study was to investigate correlations of the incidence of common cancers with food groups, total energy, smoking, and SEP. In an ecological study, disaggregated cancer data through the National Cancer Registry in Iran (2008) and dietary intake, smoking habits and SEP obtained through a population based survey within the Urban Health Equity Assessment (Urban-HEART) project were correlated across 22 districts of Tehran. Consumption of fruit, meat and dairy products adjusted for energy were positively correlated with bladder, colorectal, prostate and breast and total cancers in men and women, while these cancers were adversely correlated with bread and fat intake. Also prostate, breast, colorectal, bladder and ovarian cancers had a positive correlation with SEP; there was no correlation between SEP and skin cancer in both genders and stomach cancer in men. The incidence of cancer was higher in some regions of Tehran which appeared to be mainly determined by SEP rather than dietary intake. Further individual data are required to investigate reasons of cancer clustering.

Thisarticle presents an adaptive neuro-fuzzy inference system (ANFIS) for classification of low magnitude seismic events reported in Iran by the network of Tehran Disaster Mitigation and Management Organization (TDMMO). ANFIS classifiers were used to detect seismic events using six inputs that defined the seismic events. Neuro-fuzzy coding was applied using the six extracted features as ANFIS inputs. Two types of events were defined: weak earthquakes and mining blasts. The data comprised 748 events (6289 signals) ranging from magnitude 1.1 to 4.6 recorded at 13 seismic stations between 2004 and 2009. We surveyed that there are almost 223 earthquakes with M ≤ 2.2 included in this database. Data sets from the south, east, and southeast of the city of Tehran were used to evaluate the best short period seismic discriminants, and features as inputs such as origin time of event, distance (source to station), latitude of epicenter, longitude of epicenter, magnitude, and spectral analysis (fc of the Pg wave) were used, increasing the rate of correct classification and decreasing the confusion rate between weak earthquakes and quarry blasts. The performance of the ANFIS model was evaluated for training and classification accuracy. The results confirmed that the proposed ANFIS model has good potential for determining seismic events.

Background Global payment system is a first example of per-case payment system that contains 60 commonly used surgical operations for which payment is based on the average cost per case in Iran. Objective The aim of the study was to determine the amount of reduction, increase or no change in the trend of global operations. Methods In this retrospective longitudinal study, data on the 60 primary global surgery codes was gathered from Tehran Health Insurance Organization within the ten-year period of 2005–2015 separately, for each month. Out of 60 surgery codes, only acceptable data for 46 codes were available based on the insurance documents sent by medical centers. A quantitative analysis of time series through Regression Analysis Model using STATA software v.11 was performed. Results Some global surgery codes had an upward trend and some were downwards. Of N Codes, N83, N20, N28, N63, and N93 had an upward trend (p<0.05) and N32, N43, N81 and N90 showed a significant downward trend (p<0.05). Similarly, all H Codes except for H18 had a significant upward trend (p<0.000). As such, K Codes including K45, K56 and K81 had an increasing movement. S Codes also experienced both increasing and decreasing trends. However, none of the O Codes changed according to time. Other global surgical codes like C61, E07, M51, L60, J98 (p<0.000), I84 (p<0.031) and I86 (p<0.000) shown upward and downward trends. Total global surgeries trend was significantly upwards (B=24.26109, p<0.000). Conclusion The varying trend of global surgeries can partly reflect the behavior of service providers in order to increase their profits and minimize their costs. PMID:29765576

Asymptomatic bacteriuria is one of the common problems in pregnancy. Asymptomatic bacteriuria is associated with pyelonephritis, preterm labor and low birth weight infants. The physiological and anatomical changes in pregnancy facilitate urinary tract infection (UTI) during pregnancy. Several tests are available for diagnosis of asymptomatic bacteriuria. The urine culture is a gold standard diagnostic test for asymptomatic bacteriuria but it is expensive and time-consuming. Screening methods may be useful in detecting high-risk pregnant women for asymptomatic bacteriuria. The aim of the present study was to compare urine analysis as a rapid screening test to urine culture in diagnosis of asymptomatic bacteriuria. A total of 123 pregnant women attending the obstetrics clinic of Boo-Ali hospital in Tehran, Iran from March 2013 to September 2014 were included in the present diagnostic cross-sectional study. One hundred twenty three mid-stream urine samples were inoculated into cultures and were processed by dipstick (nitrite test and leucocyte esterase test) and microscopic pus cell count. The sensitivity, specificity, positive predictive value and negative predictive value of nitrite test, leucocyte esterase test and microscopic pus cell count were compared with urine culture in diagnosis of asymptomatic bacteriuria by using SPSS version 19. Of 123 urine samples, significant asymptomatic bacteriuria (≥10 4 cfu/Ml) was detected in 8 (6.5%) subjects. The sensitivity and specificity of nitrite test were 37% and 100% respectively. The sensitivity of pus cell count alone and leucocyte esterase test alone were 100% but the specificity of them were 64% and 65% respectively. We found high negative predictive value by Pus cell count and the leucocyte esterase test (100%) and low positive predictive value by them (16% and 17% respectively). Urine culture is the most useful test for diagnosis of asymptomatic bacteriuria. None of our screening tests had a sensitivity and specificity of 100%, whereas we can only refer the pregnant women with positive leucocyte esterase test and significant pyuria to the urine culture.

Transverse beam dynamics of an 8 MeV low current (10 mA) S-band traveling wave electron linear accelerator has been studied and optimized. The main issue is to limit the beam emittance, mainly induced by the transverse RF forces. The linac is being constructed at Institute for Research in Fundamental Science (IPM), Tehran Iran Labeled as Iran's First Linac, nearly all components of this accelerator are designed and constructed within the country. This paper discusses the RF coupler induced field asymmetry and the corresponding emittance at different focusing levels, introduces a detailed beam dynamics design of a solenoid focusing channel aiming to reduce the emittance growth and studies the solenoid misalignment tolerances. In addition it has been demonstrated that a prebuncher cavity with appropriate parameters can help improving the beam quality in the transverse plane.

Fuel consumption has significantly increased due to the growth of the population. A solution to address this problem is the underground storage of natural gas. The first step to reach this goal is to select suitable places for the storage. In this study, site selection for the underground natural gas reservoirs has been performed using a multi-criteria decision-making in a GIS environment. The "Ordered Weighted Average" (OWA) operator is one of the multi-criteria decision-making methods for ranking the criteria and consideration of uncertainty in the interaction among the criteria. In this paper, Fuzzy AHP_OWA (FAHP_OWA) is used to determine optimal sites for the underground natural gas reservoirs. Fuzzy AHP_OWA considers the decision maker's risk taking and risk aversion during the decision-making process. Gas consumption rate, temperature, distance from main transportation network, distance from gas production centers, population density and distance from gas distribution networks are the criteria used in this research. Results show that the northeast and west of Iran and the areas around Tehran (Tehran and Alborz Provinces) have a higher attraction for constructing a natural gas reservoir. The performance of the used method was also evaluated. This evaluation was performed using the location of the existing natural gas reservoirs in the country and the site selection maps for each of the quantifiers. It is verified that the method used in this study is capable of modeling different decision-making strategies used by the decision maker with about 88 percent of agreement between the modeling and test data.

Medical nano-gold radioisotopes is produced regularly using high-flux nuclear reactors, and an accelerator-driven neutron activator can turn out higher yield of (197)Au(n,γ)(196,198)Au reactions. Here, nano-gold production via radiative/neutron capture was investigated using irradiated Tehran Research Reactor flux and also simulated proton beam of Karaj cyclotron in Iran. (197)Au nano-solution, including 20nm shaped spherical gold and water, was irradiated under Tehran reactor flux at 2.5E+13n/cm(2)/s for (196,198)Au activity and production yield estimations. Meanwhile, the yield was examined using 30MeV proton beam of Karaj cyclotron via simulated new neutron activator containing beryllium target, bismuth moderator around the target, and also PbF2 reflector enclosed the moderator region. Transmutation in (197)Au nano-solution samples were explored at 15 and 25cm distances from the target. The neutron flux behavior inside the water and bismuth moderators was investigated for nano-gold particles transmutation. The transport of fast neutrons inside bismuth material as heavy nuclei with a lesser lethargy can be contributed in enhanced nano-gold transmutation with long duration time than the water moderator in reactor-based method. Cyclotron-driven production of βeta-emitting radioisotopes for brachytherapy applications can complete the nano-gold production technology as a safer approach as compared to the reactor-based method.

Cancer is currently one of the main public health problems all over the world and its economic burden is substantial both for health systems and for society as a whole.To inform priorities for cancer control, we here estimated years of potential life lost (YPLL) and productivity losses due to cancer-related premature mortality in Iran from 2006 to 2010. The number of cancer deaths by sex and age groups for top ten leading cancers in Iran were obtained from the Ministry of Health and Medical Education. To estimate theYPLL and the cost of productivity loss due to cancer-related premature mortality, the life expectancy method and the human capital approach were used, respectively. There were 138,228 cancer-related deaths in Iran (without Tehran province) of which 76 % (106,954) were attributable to the top 10 ranked cancers. Some 63 % of total cancer-related deaths were of males. The top 10 ranked cancers resulted in 106,766,942 YPLL in total, 64,171,529 (60 %) in males and 42,595,412 (40%) in females. The estimated YPPLL due to top 10 ranked cancers was 58,581,737 during the period studied of which 32,214,524 (54%) was accounted for in males.The total cost of lost productivity caused by premature deaths because of top 10 cancers was 1.68 billion dollars (US$) from 2006 to 2010, ranging from 251 million dollars in 2006 to 283 million dollars in 2010. This study showed that the economic burden of premature mortality attributable to cancer is significant for Iranian society. The findings provide useful information about the economic impact of cancer for health system policy/ decision makers and should facilitate planning of preventive intervention and effective resource allocation.

Food security has been defined as the "availability, stability, access and utilization of safe foods". Diabetes has been known as one of the biggest health and medical problems throughout the world and is clearly related to lifestyle, and particularly, improper food consumption. The aim of this study was to determine the relationship between food security with sugar and blood pressure in patients suffering from type 2 diabetes who refer to diabetes centers in Tehran. This cross-sectional study was conducted in 2015 on type 2 diabetes patients in Tehran, Iran. From two diabetes centers in the eastern and southern parts of Tehran, 243 type 2 diabetes patients were selected. Necessary information (demographic and food security information) about all the studied persons was collected using the standard questionnaire verified by US Department of Agriculture (USDA). The data was analyzed by SPSS version 16, statistical comparisons were made using analysis of variance (ANOVA) and Chi-square and Tukey tests and a significant level of <0.05. Most subjects were female (68.7%). There was no significant relationship between gender and food security (p=0.372). No significant relation was observed between food security and fasting blood pressure, HbA1C, and systolic blood pressure (p>0.05), but there was a significant relationship between food security and diastolic blood pressure (p= 0.030). According to the relationship between diastolic blood pressure and food security and the role of blood pressure in the irreparable diabetic complications, it is recommended to perform appropriate food advice.

An estimation of traffic related CO2 emissions from motor vehicles in the capital city of, Iran

2012-01-01

Vehicle exhaust is a major source of anthropogenic carbon dioxide (CO2) in metropolitan cities. Popular community mode (buses and taxies) and about 2.4 million private cars are the main emission sources of air pollution in Tehran. A case survey has conducted to measure CO2 in four popular vehicles, bus, taxi, private car and motorcycle, which moved in the city with respectively 7800, 82358, 560000 and 2.4 million per day in 2012. Results indicated that the contribution of CO2 emissions increased in the following order: private car, motorcycle, bus and taxi. The overall average for the contribution of CO2 emissions in the private car, motorcycle, bus, and taxi were 26372, 1648, 1433 and 374 tons per day, respectively. Our results also showed that the urban transport operation consume an estimated 178 and 4224 million liter diesel and petrol per year, respectively, that have released about 10 million tons of CO2. The average contribution of CO2 emissions of private cars in Tehran was higher (88%) than other vehicles. It was concluded that high volume of traffic, transport consumption of fossil fuels and shortage of adequate public transport system are responsible for the high CO2 level in environment in Tehran. Thus, it is to be expected that CO2 as a greenhouse gas has risen in Tehran more than ever in the following years and this would be a matter of concern for the authorities to have a comprehensive plan to mitigate this phenomena.

Assessment of job satisfaction of the faculty members and its underlying factors may increase career fulfillment and raise the educational and research productivity, leading to higher quality of dental services at the community level, ultimately improving public oral health status. This study assessed job satisfaction and its influential factors in dental academic members in Tehran. The job satisfaction level of 203 faculty members was assessed using a Likert scale questionnaire from 0 to 4, with 4 representing very satisfied and 0 not at all satisfied. The analysis of variance was used to compare the responses among dental faculty members of three different universities. The impact of age, gender, academic rank, employment status and the date of employment on the overall faculty job satisfaction was identified by multiple linear regression analysis. The mean professional satisfaction score among faculty members was 1.5 (0.5) out of four. Among the studied underlying factors, only the date of employment was seen to have a statistically significant impact on the faculties' overall job satisfaction (P= 0.05). There was no difference in job compensation observed between the three dental faculties. Dissatisfying aspects of the academic work included educational and research policies, monetary strategies, quality of leadership and administration, promotion and tenure policies, job security, educational environment, equipments, and facilities. The only satisfying factor was the interaction between faculty colleagues and students. Faculty members of Tehran Dental Schools are dissatisfied with their work environments in Tehran Dental Schools. Issues such as salary and remuneration, facilities, equipments, promotion and tenure policies are strongly believed to account for the dissatisfaction.

Climate change has been identified as a leading human and environmental crisis of the twenty-first century. Drylands throughout the world have always undergone periods of degradation due to naturally occurring fluctuation in climate. Persistence of widespread degradation in arid and semiarid regions of Iran necessitates monitoring and evaluation. This paper aims to monitor the desertification trend in three types of land use, including range, forest and desert, affected by climate change in Tehran province for the 2000s and 2030s. For assessing climate change at Mehrabad synoptic station, the data of two emission scenarios, including A2 and B2, were used, utilizing statistical downscaling techniques and data generated by the Statistical DownScaling Model (SDSM). The index of net primary production (NPP) resulting from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images was employed as an indicator of destruction from 2001 to 2010. The results showed that temperature is the most significant driving force which alters the net primary production in rangeland, forest and desert land use in Tehran province. On the basis of monitoring findings under real conditions, in the 2000s, over 60 % of rangelands and 80 % of the forest were below the average production in the province. On the other hand, the long-term average changes of NPP in the rangeland and forests indicated the presence of relatively large areas of these land uses with a production rate lower than the desert. The results also showed that, assuming the existence of circumstances of each emission scenarios, the desertification status will not improve significantly in the rangelands and forests of Tehran province.

Internet addiction is a global phenomenon that causes serious problems in mental health and social communication. Students form a vulnerable group, since they have free, easy, and daily access to the internet. The current study aimed to investigate perceived social support, self-esteem, and internet addiction among Al-Zahra University students. In the current descriptive research, the statistical sample consisted of 101 female students residing at AL-Zahra University dormitory, Tehran, Iran. Participants were randomly selected and their identities were classified. Then, they completed the Multidimensional Scale of Perceived Social Support, Rosenberg's Self-esteem Scale, and Yang Internet Addiction Test. After completion of the questionnaires, the data were analyzed using the correlation test and stepwise regression. The Pearson correlation coefficient indicated significant relationships between self-esteem and internet addiction (P < 0.05, r = -0.345), perceived social support (r = 0.224, P < 0.05), and the subscale of family (r = 0.311, P < 0.05). The findings also demonstrated a significant relationship between internet addiction and perceived social support (r = -0.332, P < 0.05), the subscale of family (P < 0.05, r = -0.402), and the other subscales (P < 0.05, r = -0.287). Results of the stepwise regression showed that the scale of internet addiction and the family subscale were predicative variables for self-esteem (r = 0.137, P < 0.01, F2, 96 = 77.7). Findings of the current study showed that persons with low self-esteem were more vulnerable to internet addiction.

The aim of the current study was to measure glutaraldehyde, acetic acid and sulfur dioxide and levels inside wet x-ray processing areas in a developing country and comparing data with those in developed countries. Forty-five radiographers from 10 educational hospitals affiliated to the Tehran University of Medical Sciences (TUMS) in Tehran, Iran participated in this descriptive-analytical study. Exposure to glutaraldehyde (a constituent of developer chemistry), acetic acid (a constituent of fixer chemistry) and sulfur dioxide (a byproduct of sulfites present in both developer and fixer solutions) was measured in all participants as well as area exposure. Average full-shift exposure to glutaraldehyde, acetic acid and sulfur dioxide were 0.0018, 2.65 and 1.64 mg m(-1), respectively. The results showed that the TUMS radiographers full-shift exposures are generally lower than the American Conference of Governmental Industrial Hygienists (ACGIH) recommended levels. The concentration of glutaraldehyde collected by area sampling (darkroom) was almost five times (0.0104 mg m(-3)) greater than taken by personal sampling. Exposure to the chemical pollutants in the currents study were generally higher than in developed countries. Identification of these key exposure determinants is useful in targeting exposure evaluation and controls to reduce developer and fixer chemicals exposures in the radiology departments. Employing of a digital imaging system that do not involve wet x-ray processing of photographic film would be a useful device for radiographers protection.

Electrical burns are associated with significant morbidity and mortality, which are usually preventable with simple safety measures. We conducted a retrospective study of non-lightening electrocution deaths in Tehran, Iran, between 2002 and 2006. Of 295 deaths, 285 investigated were accidental. The remnants were suicidal. The age range was 11 months to 75 years with a mean age of 28.99 + or - 12.58 years. Two hundred seventy-nine victims (96.6%) were males. The upper extremity was the most frequently involved contact site in 185 deaths (66.3%). No electrical burn marks were present in 16 (5.4%) cases. Workrelated accidents were responsible for 188 cases deaths (63.9%) and home accident for 85 cases deaths (28.8%). Deaths were caused most frequently by touching an electrical cable (95 cases, 32.2%). There was an increase in electrocution deaths in the summer (119 cases, 40.3%). One hundred seventy-nine cases (60.7%) were dead on the scene of death and 94 cases (31.9%) were dead on arrival at hospital. The unique findings of our study include 10 cases (3.4%) of suicidal electrocution and a high rate of workrelated accidental electrocution among Afghan workers. Death rates from electrocution among all medico-legal deaths were found to be lower in our study than in previous reports, most of them were work-related and preventable. Workers and their employers should be educated to avoid such accidents with safety measures.

In hospitals, the pharmacy information system (PIS) is usually a sub-system of the hospital information system (HIS). The PIS supports the distribution and management of drugs, shows drug and medical device inventory, and facilitates preparing needed reports. In this study, pharmacy information systems implemented in general teaching hospitals affiliated to medical universities in Tehran (Iran) were evaluated using a multi-dimensional tool. This was an evaluation study conducted in 2015. To collect data, a checklist was developed by reviewing the relevant literature; this checklist included both general and specific criteria to evaluate pharmacy information systems. The checklist was then validated by medical informatics experts and pharmacists. The sample of the study included five PIS in general-teaching hospitals affiliated to three medical universities in Tehran (Iran). Data were collected using the checklist and through observing the systems. The findings were presented as tables. Five PIS were evaluated in the five general-teaching hospitals that had the highest bed numbers. The findings showed that the evaluated pharmacy information systems lacked some important general and specific criteria. Among the general evaluation criteria, it was found that only two of the PIS studied were capable of restricting repeated attempts made for unauthorized access to the systems. With respect to the specific evaluation criteria, no attention was paid to the patient safety aspect. The PIS studied were mainly designed to support financial tasks; little attention was paid to clinical and patient safety features.

Gender inequality harms the health of millions of women and girls in all over the world. This study aimed to identify the state of gender equity in the health sector of the Islamic Republic of Iran. This study was based on the secondary analysis of the available data in four provinces. The research team held three sessions to select the appropriate indicators for measuring gender equity in Iran. Moreover, using the data of different sources, the indexes were evaluated by applying the brain storming method. To demonstrate the difference between females and males, the ratio of females to males was measured in each indicator. The confidence intervals were used to show significant differences in the gap between men and women. Educational indicators were analyzed using the appraisal framework of UNESCO and International Institute for Education Planning. Findings revealed gender equality in the indicators of education and under-five underweight in all the provinces. However, the indicator of information on the mild psychological diseases showed inequality in favor of males. Infants' mortality, under-five mortality, crude death, drug abuse and smoking showed inequality in favor of females in all the four provinces. The incidence of tuberculosis, severe psychological diseases, and basic and supplementary insurance coverage was equal in all provinces except Tehran. This study revealed gender inequality in many indicators among the provinces. Therefore, improving this condition requires policymaking, planning, and conducting appropriate strategies with proper gender approaches.

Background: Asthma is the first cause of children hospitalization and need for emergency and impose high economic burden on the families and governments. We aimed to investigate the economic burden of pediatric asthma and its contribution to family health budget in Iran. Methods: Overall, 283 pediatric asthmatic patients, who referred to two tertiary pediatric referral centers in Tehran capital of Iran, included from 2010–2012. Direct and indirect asthma-related costs were recorded during one-year period. Data were statistically analyzed for finding association between the costs and factors that affect this cost (demographic variables, tobacco smoke exposure, control status of asthma and asthma concomitant diseases). Results: Ninety-two (32.5%) females and 191(67.5%) males with the age range of 1–16 yr old were included. We found the annual total pediatrics asthma related costs were 367.97±23.06 USD. The highest cost belonged to the medications (69%) and the lowest one to the emergency (2%). We noticed a significant increasing in boys’ total costs (P=0.011), and 7–11 yr old age group (P=0.018). In addition, we found significant association between total asthma costs and asthma control status (P=0.011). Conclusion: The presence of an asthmatic child can consume nearly half of the health budget of a family. Our results emphasis on improving asthma management programs, which leads to successful control status of the disease and reduction in economic burden of pediatric asthma. PMID:29445636

In the last decades cancer has become one of the important causes of death in Iran .This study examined perspective of a group of Iranian health professionals, patients and patients' family members regarding their view on disclosure of cancer information at a university hospital in Tehran, Iran. The method of study was qualitative semi-structured focused group content analysis. Two group leaders (psychologist and psychiatrist) run the focus groups. Oncologists, nurses, patients and family members participated in separate focus groups. Five group sessions were held to sum up the participants views in four major topics related to disclosure of cancer information to patients and families. Most of physicians and nurses believed that disclosure of cancer diagnosis is a mistake. Family members think that it should be delivered gradually during stages of therapy based on patient's psychological state, but most of the patients consider truth telling as a patient right. All physicians, most of nurses and all the patients see the physician as a person responsible to break the diagnostic disclosure. All patients wanted the physicians to take the total control of decision-making process for their treatment. Iranian physicians and nurses hesitate to disclose cancer diagnosis compared to patients, who want to know the truth. Patients, nurses and physicians consider the physician to be the person responsible for delivering the information of cancer diagnosis .Development and implementation of a protocol based on Iranian culture is a necessity.

The study determined the prevalence of food insecurity and its sociodemographic determinants among Afghan immigrants in two major cities of Iran. This cross-sectional study was conducted on a sample of 310 adult females from immigrant Afghan households in Tehran (n=155) and Mashhad (n=155), who were recruited through multistage sampling. Data were collected through face-to-face interviews, using a questionnaire. Food security was measured by a locally-adapted Household Food Insecurity Access Scale. More than 60% suffered from moderate-to-severe food insecurity, 37% were mildly food-insecure while about 23% were food-secure. Food insecurity was significantly more prevalent in female-headed households, households whose head and spouse had lower level of education, belonged to the Sunni sect, and those with illegal residential status, unemployment/low job status, not owning their house, low socioeconomic status (SES), and living in Mashhad. Prevalence of food insecurity was relatively high among Afghan immigrants in Iran. This calls for the need to develop community food security strategies for ensuring their short- and long-term health. PMID:24288950

Background: Training methods that enhance nurses’ learning and retention will increase the quality of patient care. This study aimed to compare the effectiveness of electronic learning and educational booklet on the nurses’ retention of diabetes updates. Methods: In this controlled trial study, convenience sampling was used to select 123 nurses from the endocrinology and internal medicine wards of three hospitals affiliated to Tehran University of Medical Sciences (Tehran, Iran). The participants were allocated to three groups of manual, electronic learning, and control. The booklet and electronic learning groups were trained using educational booklet and electronic continuous medical education (CME) website, respectively. The control group did not receive any intervention. In all the three groups, the nurses' knowledge was measured before the intervention, and one and four weeks after the intervention. Data were collected by a questionnaire. Results: Significant differences were observed between the mean scores of the three groups one and four weeks after the intervention (F=26.17, p=0.001 and F=4.07, p=0.020, respectively), and post hoc test showed that this difference was due to the higher score in e-learning group. Both e-learning and booklet methods could effectively improve nurses' knowledge (χ²=23.03, p=0.001 and χ²=51.71, p=0.001, respectively). Conclusion: According to the results of this study, electronic learning was more effective than booklet in enhancing the learning and retention of knowledge. Electronic learning is suggested as a more suitable method as it provides appropriate interactions and attractive virtual environments to motivate the learners and promote retention. PMID:27493908

Background: Mental health is considered as an integral and essential component of overall health. Its determinants and related factors are one of the most important research priorities, especially in adolescents and young people. Using a qualitative approach, the present study aimed to identify factors affecting the mental health of youth in Iran. Methods: In 2017, following content analysis principles, and using semi-structured in-depth interviews, we conducted a qualitative study exploring the opinions of young people about mental health. A targeted sampling method was used, and participants were young volunteers aged 18 to 30 who were selected from Tehran province, Iran. Inclusion criteria for participants was willingness to participate in the study, and ability to express their experiences. Data collection was done with individual in-depth interviews. According to the explanatory model, the interviews were directed toward the concept of mental health and path of causality and auxiliary behaviors. Results: 21 young adults participated, who met the study inclusion criteria, of whom 12 participants were male. Their mean age was 24.4 ± 0.41 years and their education varied from primary school to Master’s degree. Mental health was considered as mental well-being and a sense of satisfaction and efficacy, not only the presence of a disease or mental disorder. Based on the opinions of the interviewees, three factors of personal characteristics, family and society are involved in mental health. Individual factors were associated with behavioral and physical problems. One of the most important issues was revealed as tensions in societal and family conflicts. Economic problems and unemployment of young people were also extracted from the social factor. Conclusion: In Iran, social factors such as jobs for the unemployed and job security are considered as important determinants in the mental health of young people. PMID:29560255

People living with HIV/AIDS (PLHA) face several challenges in terms of the medical management of their disease. Alongside this are stigma, discrimination and psychosocial issues associated with HIV infection. In this study, the relationships associated with HIV-related stigma, mental health and quality of life for HIV-positive patients were investigated. This cross-sectional study examined a sample of 450 HIV positive patients from the Infectious Diseases and Behavioral Health Clinic of Imam Khomeini Hospital in the city of Tehran, Iran. PLWHA completed Socio-Demographic Characteristics, Berger Scale Stigma (BSS), General Health Questionnaire (GHQ-28), WHO Quality of life-BREF (WHOQOL-BREF) and Philips Social Support Appraisals (SSA). Stigma was significantly correlated with psychological variables, social support, and quality of life. A prevalence of psychiatric disorders was reported by 78.8%. Findings suggested that psychosocial interventions reduce HIV related stigma, address psychological disorders and build social support to improve quality of life for people living with HIV.

While long-term exposure to air pollutants is associated with an increase in heart diseases and mortality, little information is available about the short-term effects of air pollution. This case-crossover study assessed the relationship of particulate matter (PM10) and carbon monoxide (CO) levels with hospital admission for acute coronary syndrome in Tehran, Islamic Republic of Iran. We interviewed 250 patients with a first episode of acute coronary syndrome and obtained data from hospital records and Tehran Air Quality Control Company. The risk of acute coronary syndrome was significantly associated with elevated concentrations of CO the day before the event (OR 1.18; 95% CI: 1.03-1.34) but not significantly with PM10 (OR 1.00; 95% CI: 0.99-1.02). Stratification by age, sex, diabetes, hypertension and smoking status did not affect the results, but women were more susceptible than men to CO levels (OR for women/men 1.68; 95% CI: 1.25-2.26).

Background Infertility may prevent couples to achieve the desired social roles and lead to some social and psychological problems. This study aimed to explain the social consequences of infertility in Iranian women seeking treatment. Materials and Methods A qualitative content analysis was conducted based on 32 semi-structured interviews with 25 women affected by primary and secondary infertility with no surviving children. The participants were purposefully selected with maximum variability from a fertility health research center in Tehran, Iran, from January to October 2012. Data were collected using semi-structured interviews and analyzed using the conventional content analysis method. Results Our findings indicate that the consequences of infertility are divided into five main categories: 1. violence including psychological violence and domestic physical violence, 2. marital instability or uncertainty, 3. social isolation including avoiding certain people or certain social events and self-imposed isolation from family and friends, 4. social exclusion and partial deprivation including being disregarded by family members and relatives and reducing social interactions with the infertile woman and 5. social alienation. Conclusion This study reveals that Iranian women with fertility issues seeking treatment face several social problems that could have devastating effects on the quality of their lives. It is, therefore, recommended that, in Iran, infertility is only considered as a biomedical issue of a couple and pay further attention to its sociocultural dimensions and consequences.

Objective: In line with Iran’s Comprehensive Health Sector Road Map, the National Institute of Health Research at the Tehran University of Medical Sciences developed the 2012-2025 road map of Disaster Health Management (DHM), including goals and objectives, strategies, activities and related prerequisites. This article presents the process and results of this road mapping project. Methods: The project started with an expanded literature review followed by stakeholder analysis to assess level of interest and impact of related organizations to DHM; STEEP.V methodology to define determinants with a potential impact on Iran’s HDM for duration of 2012 to 2025; strength, weakness, opportunity and threat (SWOT) analysis and formulation of goals and objectives, strategies, activities, and prerequisites. Brainstorming, group discussion and interviews with key informants were used for data collection; nominal group technique was used whenever prioritization was necessary, and Delphi panel methodology was applied for consensus development. Results: STEEP.V analysis revealed the most important Social, Technological, Environmental, Economic, Political and Value-based determinants. Iran’s DHM mission and vision were defined respectively as “Mitigation from, preparedness for, response to and recovery from consequences of natural and man-made hazards at the community level as well as to the health facilities and resources of I.R.Iran” and “In 2025, Iran’s DHM will be the most developed system in the region resulting in the least vulnerability, the highest readiness in health facilities and resources, and the highest and most effective contribution of the Iranian community to disaster resilience”, respectively. Sixteen strategies and related activities, along with the necessary prerequisites, were developed. Conclusions: This was the first attempt at comprehensive strategic planning in the field of DHM in Iran. The current framework provides Iran’s health system with a list of strategies and activities to be considered in operational planning and actions. However, a dynamic process of evaluation and revision is required to ensure that Iran’s health system goals are met by 2025.

To determine the nature and extent of Iranian casualties by ballistic missile attacks during the eight years of the Iraq-Iran war. The data collected about Iraqi missile strikes on Iranian cities included the following: date and time, number and type of missiles, cities targeted, and injuries and deaths resulting from impacts of missiles in civilian areas. The data were extracted from a database that was constructed by the army staff headquarters based on daily reports of Iranian army units during the war. Over a period of eight years (1980-1988), Iraqi army fired 533 ballistic missiles at Iranian territories. From those, 414 missiles (77.7%) landed on Iranian cities. The impacts of these missiles caused the deaths of 2,312 civilians and injured 11,625 others. Three types of ballistic missiles were used: FROG-7, Scud, and Al-Hussein (a modified version of the Scud missile). Twenty-seven cities in Iran were struck by Iraqi ballistic missiles. The highest mortalities from ballistic missiles were in Dezful and Tehran. Iraqi missile attacks continued for 90 months (2,748 days). Our results point to the necessity of investigating the psychological consequences of Iraqi ballistic missile attacks among survivors in 27 Iranian cities during the eight years of the Iraq-Iran war.

Epidemiological data of renal diseases is population-based and have great geographic variability. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, and clinical and laboratory features of various glomerulo-nephritidis (GNs) in Iran. In a retrospective cross sectional study, we analyzed 462 adult renal biopsies in Tehran, Iran. We determined the prevalence rate and the frequency of different clinical and laboratory findings in patients with different GNs. We also compared our results with the reports from other countries. There were 267 (57.8%) males and 195 (42.2%) females. The mean (+/- SD) age was 33.6 +/- 15.7 (range, 13-75) years. A total of 55 biopsies, which had revealed pathologies other than GNs, were excluded. Among the remaining 407 biopsies, membranous glomerulopathy (MGN) was the most common GN (23.6%), followed by IgAN (13.5%), membranoproliferative GN (MPGN) (11.5%), systemic lupus nephritis (SLE-GN) (10.6%), focal and segmental glomerulosclerosis (FSGS) (10.3%), and minimal change disease (MCD) (9.8%). Our study shows that MGN is the most common form of GN, followed by IgAN, MPGN, SLE-GN, FSGS and MCD in adult patients in Iran. A multi-center study with a larger sample size is needed for more comprehensive data in Iranian population.

Background: Residence characteristics can affect health of residents. This paper reports the development of an instrument assessing these aspects of neighborhoods. Materials and Methods: Literature search and focus group discussions with residents were carried out and relevant items were extracted. Five experts reviewed and commented on the items. An observation instrument with 54 items was composed and completed by two independent observers in 20 randomly selected locations. Due to lack of acceptable reliability in some items, the checklist was revised. The new 22-items checklist in four categories (general characteristics, public green area characteristics, access to services and undesirable features) was completed by two independent trained observers in 28 randomly selected locations. Results: The items in the final checklist had kappa statistics ranging from 0.63 to 1, with an exception of the item assessing “presence of beggars, homeless or working/street children”, with kappa as low as 0.27 due to variability of their presence in different times. Average Kappa statistics was 0.78 for general characteristics, 0.79 for public green area characteristics, 0.84 for access to services, and 0.54 for undesirable features. Conclusion: Neighborhood and health observation instrument seems to have good reliability in city of Tehran. It can probably be used in other large cities of Iran and similar cities elsewhere.

Background To assess the association of maternal hyperuricemia with adverse pregnancy outcome and neonatal metabolic, neurologic and respiratory disturbances in normotensive singleton pregnant women. Method This prospective multicentric cohort study was conducted on 404 normotensive singleton pregnant women who were admitted for delivery in Vali-Asr and Akbar-Abadi teaching hospitals of Tehran University of Medical Sciences, Tehran, Iran. Upon enrollment maternal and umbilical sera were obtained for determining uric acid levels. 1 and 5 minutes Apgar scores, the need for neonatal resuscitation and neonatal intensive care unit (NICU) admission were recorded. In case of NICU admission a neonatal blood sample was drawn for determining uric acid, blood sugar and bilirubin levels. An intracranial ultrasound imaging was also carried out for the admittd neonates for detecting intraventricular hemorrhage. Results Maternal hyperuricemia (uric acid one standard deviation greater than the appropriate gestational age) was independently associated with preterm birth (odds ratio (OR), 3.17; 95% confidence interval (CI), 2.1 – 4.79), small for gestational age delivery (OR, 1.28; 95% CI, 1.04 – 2.57), NICU admission (OR, 1.65; 95% CI, 1.12 – 2.94) and neonatal IVH (OR, 8.14; 95% CI, 1.11 – 87.1). Conclusions Maternal hyperuricemia in normotensive singleton pregnant women is significantly associated with preterm and SGA delivery and the development of neonatal IVH. PMID:24636149

Parasites and parasitic diseases have been prevalent in Iran according to Iranian ancient scholars and physicians' inscriptions dating back to 865-1496. Some protozoan diseases such as malaria and cutaneous leishmaniasis have been introduced by clinical manifestations and helminthic infections by size and morphology of the worms. Scientific studies of Parasitology started in Iran from 1833, first by foreign physicians and continued from 1909 by Iranian researchers. The pioneer medical parasitologists of Iran were Dr N. Ansari and Dr. Sh. Mofidi who established the Department of Medical Parasitology in the School of Medicine, University of Tehran, 1939. Afterward, a considerable number of researchers and professors of parasitology have been active in training and research works in the fields of medical parasitology throughout the entire nation. At present, some significant parasitic diseases such as bilharsiasis and dracunculiasis are more or less eradicated and malaria is in the elimination phase. The prevalence of most helminthic infections has considerably decreased. Most of the departments of medical Parasitology in Iran are active in training MD, MSPH and PhD students. The Iranian Society of Parasitology established in 1994 is active with many eligible members and its creditable publication, the Iranian Journal of Parasitology, published seasonally since 2006. From 1833, when the scientific studies of Parasitology have started in Iran up to 2013, many researchers have been done on various fields of medical Parasitology and parasitic diseases in Iran and 2517 papers in English and 1890 papers in Persian have been published in national and international scientific journals. In addition, more than 420 books related in the field of medical parasitology field have been published in Persian language.

More than 340 earthquakes recorded by the Institute of Geophysics, University of Tehran (IGUT) short period stations from 1996 to 2004 were analysed to estimate the S-coda attenuation in the Alborz region, the northern part of the Alpine-Himalayan orogen in western Asia, and in central Iran, which is the foreland of this orogen. The coda quality factor, Qc, was estimated using the single backscattering model in frequency bands of 1-25 Hz. In this research, lateral and depth variation of Qc in the Alborz region and central Iran are studied. It is observed that in the Alborz region there is absence of significant lateral variation in Qc. The average frequency relation for this region is Qc = 79 +/- 2f1.07+/-0.08. Two anomalous high-attenuation areas in central Iran are recognized around the stations LAS and RAZ. The average frequency relation for central Iran excluding the values of these two stations is Qc = 94 +/- 2f0.97+/-0.12. To investigate the attenuation variation with depth, Qc value was calculated for 14 lapse times (25, 30, 35,... 90s) for two data sets having epicentral distance range R < 100 km (data set 1) and 100 < R < 200 km (data set 2) in each area. It is observed that Qc increases with depth. However, the rate of increase of Qc with depth is not uniform in our study area. Beneath central Iran the rate of increase of Qc is greater at depths less than 100 km compared to that at larger depths indicating the existence of a high attenuation anomalous structure under the lithosphere of central Iran. In addition, below ~180 km, the Qc value does not vary much with depth under both study areas, indicating the presence of a transparent mantle under them.

ISS010-E-13393 (15 January 2005) --- Mt. Damavand, Iran is featured in this image photographed by an Expedition 10 crewmember on the International Space Station (ISS). Located approximately 50 kilometers to the northeast of Tehran, Mt. Damavand is an impressive stratovolcano that reaches 5,670 meters (18,598 feet) in elevation. Damavand, which is part of the Alborz mountain range that borders the Caspian Sea to the north, is believed by scientists to be a young volcano that has mostly formed during the Holocene Epoch (over approximately the last 10,000 years). The western flank of the volcano includes solidified lava flows with flow levees – “walls” formed as the side edges of flowing lava cooled rapidly, forming a chute that channeled the hotter interior lava. Two such flows with well-defined levees are highlighted by snow on the mountainside (center). Damavand is the highest peak in Iran and the highest volcano in the Middle East.

The prevalence of substance abuse among adolescents from low- and middle-income countries is increasing drastically and requires immediate intervention. The objective of this longitudinal quasi-experimental panel study was to design and implement a skill-based intervention to prevent and reduce substance use among urban adolescents who attended 2 randomly selected high-schools in Tehran, Iran. One-year post intervention data show that substance abuse, knowledge, attitudes, peer resistance skills, level of self-control, self-efficacy, and perceived susceptibility among intervention group were significantly improved, whereas level of self control and attitudes against substance abuse among the control group deteriorated. To efficiently prevent substance abuse among youth primary preventive interventions should be implemented before onset of substance abuse to improve resistance skills and provide adolescents with information and skills needed to develop anti-drug norms.

Air pollution is one of the most important problems in urban areas that always threaten citizen's health. Photochemical smog is one of the main factors of air pollution in large cities like Tehran. Usually smog is not only a part of nature, but is being analyzed as an independent matter, which highly affects on the nature. It has been used as relationship between atmospheric elements such as temperature, pressure, relative humidity, wind speed with inversion in the time of smog forming and weather map in 500 Hpa level during 9 years descriptive static by using correlation coefficient in this analyze. Results show that there is a meaningful correlation between atmospheric elements and smog forming. This relation is seen between monthly average of these elements and monthly average of smog forming. However, when temperature decreases, corresponding pressure will increase and result of this will be smog forming. Usually smog increases in cold months of year due to enter cold high pressure air masses in Iran during December and January that is simultaneous with decreasing temperature and air pressure increases and inversion height distance decreases from the earth surface which cause to integrate air pollution under its surface, will cause to form smog in Tehran. It shows a meaningful and strong relation, based on resultant relations by correlation coefficient from inversion height and smog forming, so that obtained figure is more than 60% .

Measuring the distribution of health is a part of assessing health system performance. This study aims to estimate health inequality between different socioeconomic groups and its determinants in Tehran, the capital of Iran. Self-rated health (SRH) and demographic characteristics, including gender, age, marital status, educational years, and assets, were measured by structured interviews of 2464 residents of Tehran in 2008. A concentration index was calculated to measure health inequality by economic status. The association of potential determinants and SRH was assessed through multivariate logistic regression. The contribution to concentration index of level of education, marital status and other determining factors was assessed by decomposition. The mean age of respondents was 41.4 years (SD 17.7) and 49% of them were men. The mean score of SRH status was 3.72 (range: 1-5; SD 0.93). 282 respondents (11.5%) rated their health status as poor or very poor. The concentration index was -0.29 (SE 0.03; p<0.001). Age, marital status, level of education and household economic status were significantly associated with SRH in both the crude and adjusted analyses. The main contributors to inequality in SRH were economic status (47.8%), level of education (29.2%) and age (23.0%). Sub-optimal SRH was more in lower than in higher economic status. After controlling for age, the levels of education and household wealth have the greatest contributions to SRH inequality.

Moral distress is a very common experience in the nursing profession, and it is one of the main reasons for job dissatisfaction, burnout, and quitting among nurses. For instance, morally difficult situations in taking care of child patients who are severely ill may lead to moral distress for nurses. However, most of the studies about moral distress have been conducted on nurses of special wards and adult medical centers with much focus on developed countries. Subsequently, little has been researched on this topic among nurses in other nations such as Iran, and most certainly, there has been hardly any such research involving Iranian pediatric nurses. Aim/objectives: This study was conducted to evaluate moral distress among nurses in selected pediatric hospitals in Tehran, Iran. This cross-sectional study was conducted on eligible nurses who were selected through proportional stratified sampling and who completed demographic characteristics and the pediatric version of Moral Distress Scale-Revised questionnaires. Data were analyzed using descriptive statistics, t test, one-way analysis of variance, and Pearson correlation coefficient. Participants and research context: In total, 195 pediatric nurses working at three selected children's specialized university hospitals in Tehran participated in this study. Ethical considerations: This study was evaluated and approved by the institutional review board of Tehran University of Medical Sciences. The mean and standard deviation of total score of moral distress was 106.41 ± 61.64 within a range of 10-257. Also, the difference between the mean score of moral distress of the group who had not quitted their position and those who have quit in the past was statistically significant (p = 0.043). The situation that was associated with the highest moral distress was "observing medical students performing painful procedures on patients just to gain some skill." Total score of moral distress was significantly higher among male nurses (p = 0.014), while nurses with a master's degree experienced just a higher intensity of moral distress compared to those who had a bachelor's degree (p = 0.006). Since many pediatric nurses clearly face moral distress while taking care of children, it is necessary to consider measures for preventing or decreasing situations that would lead to this distress.

To compare the incidence of gestational diabetes mellitus (GDM) in Iranian infertile women with polycystic ovary syndrome (PCOS) and women without PCOS after pregnancies resulting from either assisted reproductive technology (ART) or spontaneous as well as to determine the risk factors of GDM in PCOS women. In a cross-sectional study, we evaluated medical records of 234 spontaneous pregnant women without PCOS in Akbarabadi Women's Hospital affiliated to Tehran University of Medical Science, Tehran, Iran, along with 234 pregnant women with PCOS and 234 pregnant non-PCOS women with ART conception who were treated at Royan institute, Tehran, Iran, at the same period of time, 2012 to February 2013. Exclusion criteria were as following: maternal age ≥40, family history of diabetes in first-degree relatives, pre-pregnancy diabetes and history of gestational diabetes, history of stillbirth, recurrent miscarriage, birth weight baby ≥4kg (macrosomia), parity >4, Cushing's syndrome, congenital adrenal hyperplasia and overt hypothyroidism. The GDM diagnosis was according to American Diabetes Association (ADA) criteria. Incidence and the risk factors for GDM were evaluated. The incidence rates of GDM were 44.4%, 29.9% and 7.3% for PCOS ART, non-PCOS ART and non-PCOS spontaneous pregnant women, respectively. Multivariable logistic regression was used for determining risk factors of GDM in PCOS women with adjusted odds ratios for age, parity and hypothyroidism, the results revealed the most important and significant predictors for development of GDM in PCOS women as follow: menstrual irregularity (OR=4.2; 95% CI=1.7-10.6), serum triglycerides level ≥150mg/dL (OR=1.9; 95% CI=1.07-3.6) and pregestational metformin use (OR=0.4; 95% CI=0.2-0.7). Pregnant Iranian women with a history of infertility and PCOS are at increased risk for developing GDM. It is recommendable to perform screening test for GDM in PCOS women with ART treatment, irregular menses and high serum triglycerides level in the early stage of pregnancy. Pregestational use of metformin can be effective in reducing the occurrence of GDM. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Aim To explore the association(s) between demographic factors, socioeconomic status (SES), social capital, health-related quality of life (HRQoL), and mental health among residents of Tehran, Iran. Methods The pooled data (n = 31 519) were extracted from a population-based survey Urban Health Equity Assessment and Response Tool-2 (Urban HEART-2) conducted in Tehran in 2011. Mental health, social capital, and HRQoL were assessed using the 28-item General Health Questionnaire (GHQ-28), social capital questionnaire, and Short-Form Health Survey (SF-12), respectively. The study used a multistage sampling method. Social capital, HRQoL, and SES were considered as latent variables. The association between these latent variables, demographic factors, and mental health was determined by structural-equation modeling (SEM). Results The mean age and mental health score were 44.48 ± 15.87 years and 23.33 ± 11.10 (range, 0-84), respectively. The prevalence of mental disorders was 41.76% (95% confidence interval 41.21-42.30). The SEM model showed that age was directly associated with social capital (P = 0.016) and mental health (P = 0.001). Sex was indirectly related to mental health through social capital (P = 0.018). SES, HRQoL, and social capital were associated both directly and indirectly with mental health status. Conclusion This study suggests that changes in social capital and SES can lead to positive changes in mental health status and that individual and contextual determinants influence HRQoL and mental health.

Background: Socioeconomic status has been found to have a significant impact on the health as well as risk behaviors of adolescents across different contexts. This study was conducted to assess the effect of social relations adjusted by social class on physical and psychological well-being of adolescences in Teheran, Iran. Methods: This was a cross- sectional study and carried out on 1,742 adolescences living in Tehran during 2011. Adolescences were selected, using proportional stratified sampling method and a questionnaire was filled over an interview for data gathering. Data were analyzed, using SPSS18 logistic regression. Results: The prevalence of psychological symptoms was more than 24% and had a large range (24%-93%), while physical symptoms showed a lower prevalence with a smaller range (12%-33%). Furthermore, there was a significant relation between the adolescences gender and feeling the need for others’ help (p<0.001). Factors related to feeling the need for others help, anxiety, and worrying were the most prevalent among both boys and girls. In the section of family social relations, talking to the mother and talking to the father had the lowest and the highest prevalence among girls and boys, respectively. With respect to relations, the number of close friends and after school gathering time with close friends had the highest prevalence among girls, while the number of close friends and E-communication with close friends had the lowest and the highest prevalence among boys, respectively. Conclusion: The physical and psychological symptoms were common among adolescents from families with high socioeconomic status. PMID:28210612

Background: The trust is meant the belief of the patient to the practitioner or the hospital based on the concept that the care provider seeks the best for the patient and will provide the suitable care and treatment for him/her. One of the main determinants of patient’s trust is the service quality. Objectives: This study aimed to examine the effect of quality of services provided in private hospitals on the patient’s trust. Patients and Methods: In this descriptive cross-sectional study, 969 patients were selected using the consecutive method from eight private general hospitals of Tehran, Iran, in 2010. Data were collected through a questionnaire containing 20 items (14 items for quality, 6 items for trust) and its validity and reliability were confirmed. Data were analyzed using descriptive statistics and multivariate regression. Results: The mean score of patients' perception of trust was 3.80 and 4.01 for service quality. Approximately 38% of the variance in patient trust was explained by service quality dimensions. Quality of interaction and process (P < 0.001) were the strongest factors in predicting patient’s trust, but the quality of the environment had no significant effect on the patients' degree of trust. Conclusions: The interaction quality and process quality were the key determinants of patient’s trust in the private hospitals of Tehran. To enhance the patients' trust, quality improvement efforts should focus on service delivery aspects such as scheduling, timely and accurate doing of the service, and strengthening the interpersonal aspects of care and communication skills of doctors, nurses and staff.

Introduction Risk of developing type 2 diabetes is increased in women with previous gestational diabetes mellitus (GDM). Postpartum glycemic screening is recommended in women with recent GDM. But this screening rate is low and the reasons are unclear. The aim of this study was to explore the experiences of Iranian women with recent GDM on barriers of postpartum screening for diabetes. Methods This qualitative study was conducted in Tehran, Iran in 2016. Semi-structured interview was used for data collection. 22 women with recent GDM were interviewed. These women gave birth in Tehran hospitals at a minimum of 6 months before interview. The missed screening defined as not attending to laboratory for Fasting Blood Sugar and/or Oral Glucose Tolerance Test, 6 week to 6 month after their child birthing. The data was analyzed by content analysis method. Results Themes and sub-themes that illustrated the barriers to postpartum diabetes screening were: inadequate education (about developing diabetes in the future, implementation of the screening, and glucometer validity in diagnosis of diabetes), perceiving the screening as difficult (feeling comfortable with the glucometer, poor laboratory conditions, issues related to the baby/babies, and financial problems), improper attitudes toward the screening (unwilling to get diagnosed, not giving priority to oneself, having false beliefs) and procrastination (gap to intention and action, self-deception and self-regulation failure). Conclusion Women with recent GDM reported several barriers for postpartum diabetes screening. This study help to develop the evidence-based interventions for improving this screening rate.

In this study, oily sludge samples generated from a Tehran oil refinery (Pond I) were evaluated for their contamination levels and to propose an adequate remediation technique for the wastes. A simple, random, sampling method was used to collect the samples. The samples were analyzed to measure Total petroleum hydrocarbon (TPH), polyaromatic hydrocarbon (PAH) and heavy metal concentrations in the sludge. Statistical analysis showed that seven samples were adequate to assess the sludge with respect to TPH analyses. The mean concentration of TPHs in the samples was 265,600 mg kg⁻¹. A composite sample prepared from a mix of the seven samples was used to determine the sludge's additional characteristics. Composite sample analysis showed that there were no detectable amounts of PAHs in the sludge. In addition, mean concentrations of the selected heavy metals Ni, Pb, Cd and Zn were 2700, 850, 100, 6100 mg kg⁻¹, respectively. To assess the sludge contamination level, the results from the analysis above were compared with soil clean-up levels. Due to a lack of national standards for soil clean-up levels in Iran, sludge pollutant concentrations were compared with standards set in developed countries. According to these standards, the sludge was highly polluted with petroleum hydrocarbons. The results indicated that incineration, biological treatment and solidification/stabilization treatments would be the most appropriate methods for treatment of the sludges. In the case of solidification/stabilization, due to the high organic content of the sludge, it is recommended to use organophilic clays prior to treatment of the wastes.

Introduction Providing health services for adolescents requires exploration of hidden factors from the perspective of adolescents, providers, and key individuals. Understanding the process of providing health services from adolescents point of view will help receiving and continuation of services. Although many studies have been conducted in Iran on adolescents health needs, few studies have dealt with provision of these services to adolescents. Aim The present study aimed to explain the adolescents and key informants’ perception of healthcare provision. Materials and Methods The present qualitative study was conducted according to grounded theory. Data were collected using deep semi-structured individual interviews and group discussion. Participants were selected through purposive sampling followed by theoretical sampling. Participants in present study were 65 adolescents, nine youths (19-24-year-old), and 19 parents and key people involved in providing health services. Adolescents and their parents were selected from different parts of Tehran. Data collection continued until data saturation, and was analysed using Corbin-Strauss (2008) method. Results Issues relating to adolescents perception of the process of providing services included health concerns, society’s inappropriate behaviours, and weakness of the health services system in responding to adolescents needs, which as underlying factors contributed to adolescents confusion in receiving services and their proper coping with puberty. Conclusion Due to lack of education on how to manage puberty by parents, schools, society, and the health system, participating adolescents from Tehran were confused about receiving information and unable to manage puberty problems. Solving this problem requires continuity of services and interaction of family, school and community. PMID:28658809

Some Problems of American Students in Mastering Persian Phonology.

An adult learning to speak a foreign language normally retains an "accent" which may affect the intelligibility of certain sounds, but more often simply conveys the fact that the speaker is a non-native speaker. Various scholars have experimented and discussed the elements involved in a foreign accent. However, in Iran very few researchers have attempted to verify scientifically what are the phonetic and phonological aspects of an "accent." This author tried to determine whether or not a selected group of words, emphasizing stop voicing, produced by native speakers of Persian had significant phonetic and phonemic differences from those achieved by the American students. Subjects for the experiments were three groups of students, one Iranian, two American. A contrastive analysis of the Persian and the English stop consonants was made. An identical measurement test for all three groups was administered. Utilized was a Kay Sona-graph for acoustic analysis, and all spoken data from the Iranian group were compared with those of the American groups. An examination of acoustic correlates of Tehran stops produced by American students shows that the phonetically different but similar feature of /voice/ found in Tehran, Persian and English stops is intuitive to the Americans, and that the language learner cannot readily disassociate a phonological feature from habits of articulation. The results of this research support using the phonetic method for adult learners who want to improve their pronunciation ability. Further research and experimentation is necessary on the effect of the suprasegmental elements on a foreign accent and the most effective teaching materials and methods and to explore other possible techniques in the teaching process.

ABSTRACT Background: Due to many physical and mental disorders that occur in multiple sclerosis patients, identifying the factors affecting coping based on the experiences of patients using qualitative study is essential to improve their quality of life. This study was conducted to explore the antecedents of coping with the disease in patients with multiple sclerosis. Methods: This is a qualitative study conducted on 11 patients with multiple sclerosis in 2015 in Tehran, Iran. These patients were selected based on purposive sampling. Data were collected using semi-structured and in-depth interviews and coded. These data were analyzed using the conventional content analysis. The rigor of qualitative data using the criteria proposed by Guba and Lincoln were assessed. Results: Five main categories were revealed: (1) social support, (2) lenience, (3) reliance on faith, (4) knowledge of multiple sclerosis and modeling, and (5) economic and environmental situation. Each category had several distinct sub-categories. Conclusions: The results of this study showed that coping with multiple sclerosis is a complex, multidimensional and contextual concept that is affected by various factors in relation to the context of Iran. The findings of the study can provide the healthcare professionals with deeper recognition and understanding of these antecedents to improve successful coping in Iranian patients suffering from multiple sclerosis.

Background Providing care for chronic disease such as HIV is a growing challenge in the world. In order to address the challenges of linkage and care in chronic disease management, we need to identify factors that can influence people to get more involved in self-care. This study was part of an extensive qualitative study conducted in Tehran, Iran in 2016. Methods The data were collected through semi-structured interviews conducted on 25 women with HIV, and were analyzed using grounded theory. Four main themes were identified as facilitating self-care among participants: health system support, clinicians' support, family support and improved life expectancy. Sub-themes that emerged were free HIV tests; free medication; free membership in positive clubs; free psychological consultation; positive attitudes and friendly behavior from clinic staff; telephone follow up; support from husbands, mothers and peers; hope for recovery; hope for the future; and love for own children. Results Our results showed that, providing appropriate support and services, as well as a positive attitude of society towards HIV positive women, can contribute to adherence to self-care in young women with HIV. Conclusion Understanding the facilitating factors based on the patients' experiences can contribute to the development of new policies and procedures to improve the care of these patients.

In recent years, politicians have paid more attention to planning methods considering environmental, economical, social and cultural potentials of place. According to general principles and experiences has been achieved by the developed countries, there is a direct link between social security and cultural development. Where the society and region is culturally more developed, social security level is higher and vice versa. Considering this leading point, this research aims to establish a rational correlation between the provinces of Iran considering cultural development ranking and social security levels using planning models and analysis. To reach this goal, different variables in various sectors such as physical, social, economical, etc. were classified leading to developmental indicators of the provinces in the related sectors. In addition to this, many variables concerning the social security levels in provinces such as homicide, robbery, suicide, etc. were also classified to identify the social security level in each province. According to the results, more culturally developed and wealthier provinces, like Tehran, Khorasan, Fars, have lower social security degree and less culturally developed provinces, like Sistan va Baloochestan, Kurdistan, Elam have higher social security level. In other words, the mentioned principle, the correlation between social security and cultural development, does not work in the same direction in Iranian context.

Healthcare quality is affected by various factors including trust. Patients' trust to healthcare providers is one of the most important factors for treatment outcomes. The presented study identifies optimum mixture of patient demographic features with respect to trust in three large and busy medical centers in Tehran, Iran. The presented algorithm is composed of adaptive neuro-fuzzy inference system and statistical methods. It is used to deal with data and environmental uncertainty. The required data are collected from three large hospitals using standard questionnaires. The reliability and validity of the collected data is evaluated using Cronbach's Alpha, factor analysis and statistical tests. The results of this study indicate that middle age patients with low level of education and moderate illness severity and young patients with high level of education, moderate illness severity and moderate to weak financial status have the highest trust to the considered medical centers. To the best of our knowledge this the first study that investigates patient demographic features using adaptive neuro-fuzzy inference system in healthcare sector. Second, it is a practical approach for continuous improvement of trust features in medical centers. Third, it deals with the existing uncertainty through the unique neuro-fuzzy approach.

Background: Childhood obesity is a world-wide health problem and development of interventions to prevent or control it is a priority. Obesity is prevalent and on the increase among school-students in Iran, too. As the first step for development of an intervention, the current study was designed to complete our understanding of ideas, attitudes, beliefs, and preferences of primary school children in Tehran, Iran. Methods: Twenty-seven primary school-students (11 boys, 16 girls) in grade-five, most of whom were overweight or obese, participated in four focus-group discussions (FGDs). All FGD notes were analyzed to find the main themes. Results: Nine themes in three main categories emerged after analysis. The themes in the category of barriers of losing weight included environmental, psychological and physiological barriers. Category of intervention components included nutrition improvement, physical activity promotion, social support and education. Setting and deliverer of the intervention were included in the intervention conditions category. The children proposed a multi-component approach for development of an intervention. They mentioned nutrition and physical activity improvement, social support and education as the main elements of an effective intervention. Conclusions: The findings indicate that obese children need to be supported against different barriers of losing weight, mainly social barriers, especially humiliation by the community.

Background and Aim: Bronchiolitis obliterans (BO) is the main pulmonary involvement resulting from sulfur mustard (SM) gas exposure that was used against Iranian civilians and military forces during the Iran-Iraq war. The present study aimed to investigate the prevalence of gastro-esophageal reflux (GER) and gastric micro-aspiration in SM gas injured patients with chronic pulmonary diseases and recurrent episodes of exacerbations. Materials and Methods: This cross-sectional study was done at Baqiyatallah University of Medical Sciences, Tehran, Iran. Gastric micro-aspiration and GER were assessed in the enrolled patients by assessing bile acids, pepsin and trypsin in their bronchoalveolar lavage fluid. Results: Our result showed that bile acids were found to be high in 21.4% patients, and low in 53.6% of patients. Only in 16% patients, no bile was detected in the BALF. Trypsin and pepsin were detected in BAL fluid of all patients. Conclusion: Most of BO patients after exposure to SM suffer GER, while none the etiologic factors of GER in post lung transplant BO are present. It would be hypothesized that GER per se could be considered as an aggregative factor for exacerbations in patients. Further studies will provide more advances to better understanding of pathophysiological mechanism regarding GER and BO and treatment. PMID:23798946

The investigation of mutation patterns in oncogenes potentially can make available a reliable mechanism for management and treatment decisions for patients with colorectal cancer (CRC). This study concerns the rate of KRAS and BRAF genes mutations in Iranian metastatic colorectal cancer (mCRC) patients, as well as associations of genotypes with clinicopathological features. A total of 1,000 mCRC specimens collected from 2008 to 2012 that referred to the Mehr Hospital and Partolab center, Tehran, Iran enrolled in this cross sectional study. Using HRM, Dxs Therascreen and Pyrosequencing methods, we analyzed the mutational status of KRAS and BRAF genes in these. KRAS mutations were present in 33.6% cases (n=336). Of KRAS mutation positive cases, 85.1% were in codon 12 and 14.9% were in codon 13. The most frequent mutation at KRAS codon 12 was Gly12Asp; BRAF mutations were not found in any mCRC patients (n=242). In addition, we observed a strong correlation of KRAS mutations with some clinicopathological characteristics. KRAS mutations are frequent in mCRCs while presence of BRAF mutations in these patients is rare. Moreover, associations of KRAS genotypes with non-mucinous adenocarcinoma and depth of invasion (pT3) were remarkable.

Idiopathic pulmonary fibrosis (IPF) is a chronic and ultimately fatal lung disease. One of the risk factors involved in the acquisition of IPF is viral infections, especially respiratory viruses. In the present study, we investigated the detection of respiratory viruses and the possible relationship between these viruses and IPF. This cross-sectional study was supported by the Iran University of Medical Sciences (IUMS), Tehran, Iran. A total of 40 respiratory samples (five nasopharyngeal and 35 bronchoalveolar lavage specimens) were obtained from IPF patients referred to IUMS hospitals between April 2015 and December 2016. Assays were performed using the CLART Pneumovir DNA array assay, which made it possible to detect five genera of respiratory viruses simultaneously.Results/Key findings. Altogether, 22 of the 40 participants were male. Respiratory syncytial virus (RSV), parainfluenza, rhino, corona and influenza viruses were found in 2.5 % (1/40), 7.5 % (3/40), 10 % (4/40), 2.5 % (1/40) and 0% (0/40) of cases, respectively. Determining a correlation between the viruses and IPF is not an easy task, and therefore, this will require more research. In addition, the CLART Pneumovir DNA array can be considered as a useful method for simultaneous detection of several viral respiratory infections.

Descriptive cross-sectional study. Pain is a prevalent complication of individuals with spinal cord injury (SCI). Our objective was to examine the association between social support, socioeconomic factors and psychosocial factors and pain to develop more effective management strategies. Brain and Spinal Cord Injury Research (BASIR) Center, Tehran University of Medical Sciences, Tehran, Iran. The Persian version of the Brief Pain Inventory was used to measure the pain, and the Multidimensional Scale of Perceived Social Support was used to measure social support through structured face-to-face interviews in SCI individuals. The overall prevalence of pain was 50.7%; 79.3% of individuals had bilateral pain, with lower limbs and back being the most common location. The quality of pain was described as aching (41.4%), tingling (32.9%), pressure (15.7%), coldness (5.7%) and feeling electric shock sensations (4.3%). The frequency of pain in individuals with paraplegia (60.9% vs 45.7%) and incomplete (53.5% vs 52.5%) SCI was higher than with other types of neurological injuries. Patients with a medium level of education had the least pain and those with good economic situation reported higher frequency of having pain (P=0.034). There was no significant relationship between pain and social support. There was a positive correlation between pain and impairment of mood, normal work, relations with other people and lack of sleep (P<0.001). These novel findings will inform the development of strategies to manage pain by improving access to health-care facilities and supplies.

During the summer of 1994, a cross-sectional epidemiological study, in which the pulmonary function of children in Tehran was compared with pulmonary function in children in a rural town in Iran, was conducted. Four hundred children aged 5-11 y were studied. Daytime ambient nitrogen dioxide, sulfur dioxide, and particulate matter were measured with portable devices, which were placed in the children's neighborhoods on the days of study. Levels of these ambient substances were markedly higher in urban Tehran than in rural areas. Children's parents were questioned about home environmental exposures (including heating source and environmental tobacco smoke) and the children's respiratory symptoms. Pulmonary function was assessed, both by spirometry and peak expiratory flow meter. Forced expiratory volume in 1 s and forced vital capacity-as a percentage of predicted for age, sex and height-were significantly lower in urban children than in rural children. Both measurements evidenced significant reverse correlations with levels of sulfur dioxide, nitrogen dioxide, and particulate matter. Differences in spirometric lung function were not explained by nutritional status, as assessed by height and weight for age, or by home environmental exposures. Reported airway symptoms (i.e., cough, phlegm, and wheeze) were higher among rural children, whereas reported physician diagnosis of bronchitis and asthma were higher among urban children. The association between higher pollutant concentrations and reduced pulmonary function in this urban-rural comparison suggests that there is an effect of urban air pollution on short-term lung function and/or lung growth and development during the preadolescent years.

The environment is increasingly turning to a vital and very important issue for all people. By increasing environmental concerns as well as legislating and regulating rules on the protection of the environment and the emergence of green consumers, implementing green marketing approach for organizations seems to be more crucial and essential. As a result, the need for ecological products and green business activities compels companies to combine environmental issues with marketing strategies. The first step in the success of companies and organizations is to identify consumers and their consumption behaviors correctly and accurately. So, the purpose of this study is to identify effective factors for the choice of consumers of green products. We used consumption values (functional value, social value, emotional value, conditional value, epistemic value, and environmental value) as the effective factor for choosing green products. The original place of this research was in Tehran, capital city of Iran, which is one of the most polluted cities in the world due to environmental issues. The results from the survey questionnaires are analyzed using confirmatory factor analysis and structural equation modelling. The results indicated that functional value-price, functional value-quality, social value, epistemic value, and environmental value had significantly positive effects on the choice of green products; also, conditional value and emotional value had no influence on it. It was concluded that the main influential factors for consumers' choice behavior regarding green products included environmental value and epistemic value. This study emphasized the proper pricing of green products by producers and sellers.

To assess the effects of environmental exposures to trace metals on the incidence of preeclampsia, concentrations of lead (Pb), antimony (Sb), manganese (Mn), mercury, cadmium, cobalt and zinc in umbilical cord blood (UCB) and mother whole blood (MWB) were measured in 396 postpartum women without occupational exposure to metals in Tehran, Iran, using inductively coupled plasma mass spectrometry. Mother's ages ranged from 15 to 49 (mean 27) years. Preeclampsia was diagnosed in 31 subjects (7.8%). Levels of Pb, Sb and Mn in UCB were significantly higher in preeclampsia cases [mean+/-SD of 4.30+/-2.49{mu}g/dl, 4.16+/-2.73 and 46.87+/-15.03{mu}g/l, respectively] than in controls [3.52+/-2.09{mu}g/dl,more » 3.17+/-2.68 and 40.32+/-15.19{mu}g/l, respectively] (P<0.05). The logistic regression analysis revealed that one unit increase in the common logarithms of UCB concentration of Pb, Sb or Mn led to increase in the risk of preeclampsia several-fold; unit risks (95% CI) were 12.96 (1.57-107.03), 6.11 (1.11-33.53) and 34.2 (1.81-648.04) for Pb, Sb and Mn, respectively (P<0.05). These findings suggest that environmental exposure to Pb, Sb and Mn may increase the risk of preeclampsia in women without occupational exposure; levels of metals in UCB to be sensitive indicators of female reproductive toxicity as compared with those in mother MWB. Further studies are necessary to confirm these findings, especially on Sb and Mn.« less

Background: As social health is a condition-driven, dynamic and fluid concept, it seems necessary to construct and obtain a national and relevant concept of it for every society. Providing an empirical back up for Iran’s concept of social health was the aim of the present study. Methods: This study is an ecologic study in which available data for 30 provinces of Iran in 2007 were analyzed. In order to prove construct validity and obtain a social health index, an exploratory factor analysis was conducted on six indicators of population growth, willful murder, poverty, unemployment, insurance coverage and literacy. Results: Following the factor analysis, two factors of Diathesis (made up of high population growth, poverty, low insurance coverage and illiteracy) and Problem (made up of unemployment and willful murder) were extracted. The diathesis and problem explained 48.6 and 19.6% of social health variance respectively. From provinces, Sistan & Baluchistan had the highest rate of poverty and violence and the lowest rate of literacy and insurance coverage. In terms of social health index, Tehran, Semnan, Isfahan, Bushehr and Mazandaran had the highest ranks while Sistan and Baluchistan, Lurestan, Kohkiloyeh and Kermanshah occupied the lowest ones. Conclusion: There are some differences and similarities between Iranian concept of social health and that of other societies. However, a matter that makes our concept special and different is its attention to population. The increase in literacy rate and insurance coverage along with reduction of poverty, violence and unemployment rates can be the main intervention strategies to improve social health status in Iran.

Streptococcus agalactiae (Group B streptococcus, GBS) that colonize the vaginas of pregnant women may occasionally cause neonatal infections. It is one of the most common causes of sepsis and meningitis in neonates and of invasive diseases in pregnant women. It can also cause infectious disease among immunocompromised individuals. The distribution of capsular serotypes and genotypes varies over time and by geographic era. The serotyping and genotyping data of GBS in Iranian pregnant and non-pregnant women seems very limited. The aim of this study was to investigate the GBS ‎molecular capsular serotype ‎and genotype distribution of pregnant and non-pregnant carrier ‎women at Yazd university hospital, in Iran.‎. In this cross-sectional study, a total of 100 GBS strains isolated from 237 pregnant and 413 non-pregnant women were investigated for molecular capsular serotypes and surface protein genes using the multiplex PCR assay. The Chi-square method was used for statistical analysis. Out of 650 samples, 100 (15.4%) were identified as GBS, with a predominance of capsular serotypes III (50%) [III-1 (49), III-3 (1)], followed by II (25%), Ia (12%), V (11%), and Ib (2%), which was similar with another study conducted in Tehran, Iran, but they had no serotype Ia in their report. The surface protein antigen genes distribution was rib (53%), epsilon (38%), alp2/3 (6%), and alpha-c (3%). The determination of serotype and surface proteins of GBS strains distribution would ‎be ‎relevant ‎for the future possible formulation of a GBS vaccine.

The aim of the present study is to determine the characteristics of genotype and phenotype of Echinococcus granulosus derived from wild sheep and to compare them with the strains of E. granulosus sensu stricto (sheep-dog) and E. granulosus camel strain (camel-dog) in Iran. In Khojir National Park, near Tehran, Iran, a fertile hydatid cyst was recently found in the liver of a dead wild sheep (Ovis orientalis). The number of protoscolices (n=6,000) proved enough for an experimental infection in a dog. The characteristics of large and small hooks of metacestode were statistically determined as the sensu stricto strain but not the camel strain (P=0.5). To determine E. granulosus genotype, 20 adult worms of this type were collected from the infected dog. The second internal transcribed spacer (ITS2) of the nuclear ribosomal DNA (rDNA) and cytochrome c oxidase 1 subunit (COX1) of the mitochondrial DNA were amplified from individual adult worm by PCR. Subsequently, the PCR product was sequenced by Sanger method. The lengths of ITS2 and COX1 sequences were 378 and 857 bp, respectively, for all the sequenced samples. The amplified DNA sequences from both ribosomal and mitochondrial genes were highly similar (99% and 98%, respectively) to that of the ovine strain in the GenBank database. The results of the present study indicate that the morpho-molecular features and characteristics of E. granulosus in the Iranian wild sheep are the same as those of the sheep-dog E. granulosus sensu stricto strain.

The growing rate of smoking cigarettes among the youths necessitates examining its contributing factors. Accordingly, we aimed to compare smoking and nonsmoking university students in their attachment styles, perceived loneliness, and psychological well-being. To this end, we recruited 100 current smokers and 100 nonsmoking students by using a convenience sampling method from Shahid Beheshti University, Tehran, Iran. All participants completed the Adult Attachment Scale, Loneliness Scale, and General Health Questionnaire. Data analysis indicated that compared to nonsmokers, smokers had a more anxious attachment style and they felt lonelier. Moreover, current results showed that smokers suffered from higher rates of psychological problems than nonsmokers. These results suggest that smoking is influenced by a set of psychological factors and therefore, prevention and treatment programs targeting these factors may be effective in reducing the rate of smoking cigarettes among university students.

The improvement of patient safety conditions in the framework of clinical service governance is one of the most important concerns worldwide. The importance of this issue and its effects on the health of patients encouraged the researcher to conduct this study to evaluate patient safety management in the framework of clinical governance according to the nurses working in the intensive care units (ICUs) of the hospitals of the east of Tehran, Iran in 2012. This descriptive study, which was based on census method, was conducted on 250 nurses sampled from the hospitals located in the east of Tehran. For the collection of data, a researcher-made questionnaire in five categories, including culture, leadership, training, environment, and technology, as well as on safety items was used. To test the validity of the questionnaire, content validity test was conducted, and the reliability of the questionnaire was assessed by retest method, in which the value of alpha was equal to 91%. The results showed that safety culture was at a high level in 55% of cases, safety leadership was at a high level in 40% cases and at a low level in 2.04% cases, safety training was at a high level in 64.8% cases and at a low level in 4% cases, safety of environment and technology was at a high level in 56.8% cases and at a low level in 1.6% cases, and safety items of the patients in their reports were at a high level in approximately 44% cases and at a low level in 6.5% cases. The results of Student's t-test (P < 0.001) showed that the average score of all safety categories of the patients was significantly higher than the average points. Diligence of the management and personnel of the hospital is necessary for the improvement of safety management. For this purpose, the management of hospitals can show interest in safety, develop an events reporting system, enhance teamwork, and implement clinical governance plans.

A brief history of smallpox eradication in Iran.

Smallpox, which currently is only of historical interest, was once one of the most terrible illnesses with high mortality and morbidity. In the late 18th century, the English physician and naturalist, Edward Jenner (1749 - 1823), discovered an efficient preventive technique against smallpox which he termed "vaccination". Afterwards, the practice of vaccination gradually became widespread when finally in 1979, the World Health Organization formally declared the global eradication of this fatal disease.Presented here is a brief account of smallpox eradication in Iran which started on a limited scale in the 19th century by the order of Abbas Mirza (1789 - 1833), the Crown Prince of Fath Ali Shah Qajar (reign from 1797 - 1834), and reinforced in 1848 by Mirza Taghi Khan Amir Kabir (1807 - 1852) the Prime Minster of Naser ad-Din Shah, and became more popular after the establishment of the Pasteur Institute in Tehran in 1921, where considerable doses of smallpox vaccine were produced. In addition, in subsequent years, a law that mandated public smallpox vaccination was passed by the Iranian parliament (Majles) in 1953 and eventually, the mass vaccination program led to the complete eradication of smallpox in Iran in 1978.

Substance abuse has become a major public health problem in Iran. The process of developing an addiction is complex and multifaceted. Early childhood experiences are thought to be one of the important determinants of addictive behaviour. The aim of this qualitative study is to explore the early childhood experiences, especially the experiences within the immediate family, of current substance-using young adults in Iran. The study is qualitative in nature. In-depth interviews were conducted with 15 young men and women who were either in treatment for their addiction or were active drug users at the time of the interviews. Moreover, four interviews have been conducted with family members of participants. The majority of the participants experienced traumatic events during childhood and came from dysfunctional families. There appears to be a significant disconnect between these individuals and their families. An obedience-instilling parenting style and parents' knowledge and attitude toward drug using and prevention were also identified as important determinants of substance use. The results of this research point out the need for early interventions for at-risk families as well as at-risk individuals. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Organizational citizenship behavior (OCB) improves efficiency and employees' participation and generally provides a good ambiance. This study was conducted to determine the role of job satisfaction (JS), organizational commitment (OC) and procedural justice (PJ) in explaining OCB among nurses working in fifteen educational-treatment centers in Tehran-Iran, to provide guidelines for health care managers' further understanding of how to encourage citizenship behavior among nurses. In this multi-center descriptive-correlational study 373 nurses were evaluated through a Multi-stage cluster sampling method after obtaining approval from the Ethics Committee of Islamic Azad University, Tehran Medical Branch and Tehran University of Medical Sciences Research Deputy. Nurses who signed the informed consent and holding a bachelor or master degree, having a minimum one year of job experience and not having organizational management position during the questionnaire distribution were included in the study. In order to collect data, Demographic questionnaire, Podsakoff et al. (Leadersh Q 1(2):107-142, 1990) OCB questionnaire, OC questionnaire, Aelterman et al. (Educ Stud 33(3):285-297, 2007) JS questionnaire and PJ questionnaire were used. These questionnaires were translated into Persian and content validity was confirmed by an expert group; their reliability was calculated by the internal consistency Cronbach alpha coefficient and it was satisfied. Data were analyzed by descriptive statistics, Comparative mean tests, correlation coefficient and multiple-regression in the SPSS software version 11. The general mean and all five aspects of OCB that ranked higher than 3 were evaluated in a "quite desired" state. The mean for perceived procedural justice, the general mean for JS and the mean of general grade for OC from the nurses' was in "quite desired" state. Finding from multiple regression indicated that OC and PJ exhibit about 19 % of OCB variance totally which is statistically significant (P < 0.01). JS had no significant impact on explaining OCB. OC was the strongest predictor of nurses' OCB followed by perceived procedural justice. So, improving these factors can initiate better citizenship behavior among nurses.

Background: Unprecedented growth of fatalities due to traffic accidents in the recent years has raised great concerns and efforts of authorities in order to identify and control the causes of these accidents. Objectives: In the present study, the contribution of psychological, social, demographic, environmental and behavioral factors on traffic accidents was studied for young boys in Tehran, emphasizing the importance of psychosocial factors. Patients and Methods: The design of the present study was quantitative (correlational) in which a sample population including 253 boys from Tehran (Iran) with an age range of 18 to 24 who had been referred to insurance institutions, hospitals, correctional facilities as well as prisons, were selected using stratified cluster sampling during the year 2013.The subjects completed the following questionnaires: demographic, general health, lifestyle, Manchester Driving Behavior Questionnaire (MDBQ), young parenting, and NEO-Five Factor Inventory (NEO-FFI). For data analysis, descriptive statistics, correlation coefficient, and inferential statistics including simultaneous regression, stepwise regression, and structural equations modeling were used. Results: The findings indicated that in the psychosocial model of driving behavior (including lapses, mistakes, and intentional violations) and accidents, psychological factors, depression (P < 0.02), personality trait of conscientiousness (P < 0.02), failure schema due to the parenting style of mother (P = 0.001), and perception of police commands (P < 0.002), played an important role in predicting driving behavior. Among social factors, perception of police regulations (P = 0.003), had an important effect on violations and mistakes. Among environmental and behavioral factors, major factors such as driving age (P = 0.001), drug and alcohol use (P = 0.001), having driver’s license (P = 0.013), records of imprisonment or committing a crime (P = 0.012) were also able to predict occurrence of accidents. Conclusions: As the results of this study show, different factors contribute to different driving behaviors and accidents. The broad scope of these factors links accidents to other social issues and damages. PMID:26421169

Background: Health inequality monitoring especially in Health care financing field is very important. Hence, this study tends to assess the inequality in household's capacity to pay and out-of-pocket health carepaymentsin Tehran metropolis. Methods: This cross-sectional study was performed in 2013.Thestudy population was selected by stratified cluster sampling, and they constitute the typical households living in Tehran (2200 households). The required data were collected through questionnaires and analyzed using Excel and Stata v.11. Concentration Index on inequality was used for measuring inequality status in capacity to pay and household payments for health care expenses; and also the concentration index for out-of-pocket payments and capacity to pay was used to determine the extent of inequality. The recall period for inpatient care was one year and 1 month for outpatient. Results: The average of out-of-pocket payments for receiving the outpatient services was determined to be 44.33US$ and for each inpatient1861.11 US$. Concentration index for household's outof- pocket payments for inpatient health care, out-of-pocket payments for outpatient health care and health prepayments were calculated 0.13, -0.10 and -0.11, respectively. Also, concentration index in household’s capacity to pay was estimated to be 0.11whichindicatedinequality to the benefit of the rich. The households used financing strategies like savings, borrowing or lending to pay their health care expenditures. Conclusion: According to this study, the poor spend a greater portion of their capacity to pay for outpatient and inpatient health care costs and prepayment, in comparison to the rich. Thus, supporting the vulnerable groups of the society to decrease out-of-pocket payments and increasing the household’s capacity to pay through government support in order to improve the household economic potential, must be considered very important.

Negative and discriminatory attitudes towards people living with HIV/AIDS (PLWHA) are one of the biggest experienced challenges by people suffering from HIV, and these attitudes have been regarded as a serious threat to the fundamental rights of all infected people who are affected or associated with this disease in Iran. This study aimed to determine the relationship between public perception about HIV/AIDS and discriminatory attitudes toward PLWHA . The present study was conducted using a descriptive and survey design. Data were collected from 450 patients (236 male and 214 female) in Tehran and Yazd cities. The research instruments were modified HIV-related knowledge/attitude and perception questions about PLWHA, and discriminatory attitudes toward PLWHA. The results showed that prevalence of discriminatory attitudes toward PLWHA in the studied population was 60.0%. There was a significant negative correlation between citizens' awareness about HIV/AIDS, HIV-related attitudes, negative perception toward people with HIV/AIDS symptoms and their discriminatory attitudes toward PLWHA (p < .01). The hierarchical multiple regression analysis showed that components of public perception about HIV/AIDS explained for 23.7% of the variance of discriminatory attitudes toward PLWHA. Negative public perceptions about HIV/AIDS in Iran associated with discriminatory attitudes toward PLWHA and cultural beliefs in Iran tend to stigmatize and discriminate against the LWHA.

Many studies have reported that inadequate parental styles can contribute to depressive symptoms through dysfunctional cognitive styles. This study aimed to investigate the association of dysfunctional schemas and parenting style with depression, as well as the role of maladaptive schemas such as moderators and mediators in Iran and India. The study sample was selected randomly and consisted of 200 (age group 16-60 y) depressed females (mild to moderate); 100 from Tehran (Iran) and another 100 from Pune (India). The type of the research was causal-comparative. The data collection took place in hospitals and clinics in the targeted cities. Descriptive statistic tests and hierarchical multiple regression were executed (for the purpose of analyzing data) by SPSS 17. It was demonstrated that the association between parenting and depression was not moderated by early maladaptive schemas. On the contrary, the results supported meditational models in which parenting styles are associated with the cognitive schemas, and these in turn are related to depressive symptoms. It was also found that abandonment mediates the impacts of maternal style on depression in Iran. On the other hand, abandonment and punitiveness schemas mediated the relation between paternal style and depression in India. These findings suggest that the correlation between childhood experiences and depression in adulthood are mediated by dysfunctional schemas.

In this study, three different sensors of satellites including the Moderate Resolution Imaging Spectroradiometer (MODIS), Multi-angle Imaging SpectroRadiometer (MISR), and Total Ozone Mapping Spectrometer (TOMS) were used to study spatial and temporal variations of aerosols over ten populated cities in Iran. Also, the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used for analyzing the origins of air masses and their trajectory in the area. An increasing trend in aerosol concentration was observed in the most studied cities in Iran during 1979-2016. The cities in the western part of Iran had the highest annual mean of aerosol concentration. The highest aerosol optical depth (AOD) value (0.76 ± 0.51) was recorded in May 2012 over Ahvaz, and the lowest value (0.035 ± 0.27) was recorded in December 2013 over Tabriz. After Ahvaz, the highest AOD value was found over Tehran (annual mean 0.11 ± 0.20). The results show that AOD increases with increasing industrial activities, but the increased frequency of aerosols due to land degradation and desertification is more powerful in Iran. The trajectory analysis by the HYSPLIT model showed that the air masses come from Egypt, Syria, and Lebanon and passed over the Iraq and then reached to Iran during summer. Aerosol radiative forcing (ARF) has been analyzed for Zanjan (Aerosol Robotic Network site) during 2010-2013. The ARF at surface and top of the atmosphere was found to be ranging from - 79 to - 10W m -2 (average - 33.45 W m -2 ) and from - 25 to 6 W m -2 (average - 12.80 W m -2 ), respectively.

The murder of the Iranian physicist Masoud Alimohammadi last month has left the country's academic community in a state of shock. Alimohammadi, a 50-year-old physics professor at the University of Tehran, was killed on 12 January by a remote-controlled bomb attached to the side of a motorcycle outside his home. The bomb was detonated as he left for work, but the reason for the murder remained unclear as Physics World went to press. Reports by the Iranian state media blamed the US and Israel for the attack - a claim that the US later described as "absurd".

Fifty-six percent of Iranian women in the range of 17–32 years old are exposed to the highest domestic violence. Objective: The aim of this study was to design and psychoanalyze a comprehensive questionnaire on coping with domestic violence against women in Iranian society. Methods This study was carried out on a random sample of women exposed to domestic violence and referred to the health and care center of Shahid Beheshti University of Medical Sciences in Tehran, and Forensic Medical Centers in Urmia city (Iran), in 2017. Two hundred questionnaires were distributed among the participants. One hundred sixty-eight questionnaires were returned to the researchers for data analysis. Eight of those were excluded from the analysis because of incompleteness. Finally, exploratory factor analysis was performed. Results After reviewing the literature, a questionnaire with 32 items was developed. Content validity ratio (0.95) and content validity index (0.97) were obtained. The results of exploratory factor analysis indicated that the questionnaire explained 69.34% of the data variance. Cronbach’s alpha coefficient, and test-retest methods were used for determining the reliability and the obtained value, which were 0.82 and 0.81, respectively. Conclusion Validity and reliability of the questionnaire with 32 items were confirmed. The tool can be utilized to measure how women cope with domestic violence. PMID:29588816

Background: Eco-faunistic studies are inevitable step in environmental researches. Aquatic organisms like caddisflies are known as biological indicators for water quality assessment and water resource management. They have special role for energy flow in the freshwater habitats as food web and food chain among aquatic creatures. Methods: In addition to an extensive literature review on Iran Caddisflies, a field study was carried out in Lavasan river flows in north east of Tehran to collect aquatic insects using D-frame nets and or direct search on stone beneath. The water quality was measured using analytical method. Results: Literature revealed record of 62 trichopterid species in the country comprising 14 families. The most abundant species belonged to the Hydropsychidae. Herein we report presence of the Annulipalpian Hydropsyche sciligra H Malicky, 1977 in the study area. Habitat water quality of H. sciligra resembled human drinkable water. However presence of snail, Physa acuta and fish Capoeta buhsei in the water sampling area indicated inferior quality. Conclusion: From ecological point of view caddisfly larvae are predators of most important medical vectors like mosquitoes, blackflies and midges. Also they are useful and important indicator for monitoring physicochemical effects in the nature, so that they can be used for bio-monitoring program. From medical point of view, wing hairs or other body parts of caddisflies can be inhalant and contact allergens in Trichopterists and in sensitive individuals who come in contact. PMID:23785697

Abstract Background In the absence of dysphagia-oriented food products, rheological characterization of available food items is of importance for safe swallowing and adequate nutrient intake of dysphagic patients. In this way, introducing alternative items (with similar ease of swallow) is helpful to improve quality of life and nutritional intake of esophageal cancer dysphagia patients. The present study aimed at rheological characterization and cluster classification of potentially suitable foodstuffs marketed in Iran for their possible use in dysphagia diets. Methods In this descriptive study, rheological data were obtained during January and February 2012 in Rheology Lab of National Nutrition and Food Technology Research Institute Tehran, Iran. Steady state and oscillatory shear parameters of 39 commercial samples were obtained using a Physica MCR 301 rheometer (Anton-Paar, GmbH, Graz, Austria). Matlab Fuzzy Logic Toolbox (R2012 a) was utilized for cluster classification of the samples. Results Using an extended list of rheological parameters and fuzzy logic methods, 39 commercial samples (drinks, main courses and desserts) were divided to 5 clusters and degree of membership to each cluster was stated by a number between 0 and 0.99. Conclusion Considering apparent viscosity of foodstuffs as a single criterion for classification of dysphagia-oriented food products is shortcoming of current guidelines in dysphagia diets. Authors proposed to some revisions in classification of dysphagia-oriented food products and including more rheological parameters (especially, viscoelastic parameters) in the classification.

Background: Clinical learning environment is a complex social entity. This environment is effective on the learning process of nursing students in the clinical area. However, learning in clinical environment has several benefits, but it can be challenging, unpredictable, stressful, and constantly changing. In attention to clinical experiences and factors contributing to the learning of these experiences can waste a great deal of time and energy, impose heavy financial burden on educational systems, cause mental, familial and educational problems for students, and compromise the quality of patient care. Therefore, this study was carried out with the goal of determining the learning challenges of nursing students in clinical environments in Iran. Materials and Methods: In this qualitative study carried out in 2012–2013, 18 undergraduate nursing students were selected by using purposive sampling method from the Faculty of Nursing and Midwifery of Tehran and Shahid Beheshti Universities. Semi-structured interviews were used to collect data. The content analysis method was used to determine relevant themes. Results: Two themes were derived from the data analysis, which represented the students’ clinical learning challenges. These two themes included insufficient qualification of nursing instructors and unsupportive learning environment. Conclusions: Identification of the students’ clinical learning challenges and actions to remove or modify them will create more learning opportunities for the students, improve the achievement of educational goals, provide training to nursing students with the needed competencies to meet the complex demands of caring and for application of theories in practice, and improve the quality of healthcare services.

This research analyses the suburban expansion in the metropolitan area of Tehran, Iran. A hybrid model consisting of logistic regression model, Markov chain (MC), and cellular automata (CA) was designed to improve the performance of the standard logistic regression model. Environmental and socio-economic variables dealing with urban sprawl were operationalised to create a probability surface of spatiotemporal states of built-up land use for the years 2006, 2016, and 2026. For validation, the model was evaluated by means of relative operating characteristic values for different sets of variables. The approach was calibrated for 2006 by cross comparing of actual and simulated land use maps. The achieved outcomes represent a match of 89% between simulated and actual maps of 2006, which was satisfactory to approve the calibration process. Thereafter, the calibrated hybrid approach was implemented for forthcoming years. Finally, future land use maps for 2016 and 2026 were predicted by means of this hybrid approach. The simulated maps illustrate a new wave of suburban development in the vicinity of Tehran at the western border of the metropolis during the next decades.

Nutritional supplement (NS) use has increased among the general population, athletes, and fitness club participants and has become a widespread and acceptable behavior. The objective of this study was to determine the differences in sociodemographic, health-related, and psychological factors between NS users and nonusers. A case-control study design was used, whereby participants included 147 NS users (cases) and 147 nonusers (controls) age 18 yr and above who exercised at least 3 d/wk in 24 fitness clubs in Tehran. A self-administered pretested and validated questionnaire was used to collect data. The results showed that on average, NS users were younger (29.8 ± 9.5 yr) than nonusers (35.5 ± 12.2 yr). Logistic-regression analysis showed that NS use was significantly associated with moderate or high physical activity level (PAL), smoking, gender, eating attitude, and age. In conclusion, NS users were more likely to be female, younger, and smokers; to have moderate or high PAL; and to be more prone to eating disorders than nonusers.

With the increasing popularity of e-learning programs, educational stakeholders are attempting to promote critical thinking in the virtual education system. This study aimed to explore the experiences of both the instructors and the students about critical thinking promotion within the virtual education system. This qualitative study recruited the instructors and students from four academic disciplines provided by the Virtual School of Tehran University of Medical Sciences (Tehran, Iran). All programs were master's degree programs and utilized a blended (combination of e-learning and face to face) training. Semistructured interviews with the participants were used to collect data. The participants had a variety of experiences about how to promote critical thinking. These experiences were conceptualized in four main themes, namely, instructional design, educational leadership and management, local evidence, and belief systems. The present study clarified the factors affecting critical thinking promotion in e-learning. Not only the instructors but also the educational designers and leaders can benefit from our findings to improve the quality of virtual education programs and promote critical thinking.

This study aimed to investigate the relationship between health Related quality of life (HRQOL), motor ability and weight status in children. Two hundred forty children ages 9-11 yr who were selected via multi stage cluster sampling design from primary schools in the Shahre Qods at Tehran, Iran in 2007. HRQOL was assessed by the pediatric quality of life inventory (PedsQL). Motor abilities were determined by a Basic Motor Ability Test (BMAT). Body mass index was calculated to determine weight status. Psychosocial, physical, and total health related qualities of life (all P< 0.05) were significantly lowered for obese when compared to normal weight participants. In contrast, the mean scores for each HRQOL domain in motor ability category were not significant. No significant interaction was apparent when examining HRQOL scores, BMAT variables and weight status. Regardless of motor ability levels, reducing body weight among children is a potential avenue for promoting improved HRQOL. Over weight boys reported significantly worse school performance than over weight girls, suggesting the importance in considering such dimensions in programs aimed at further understanding obesity in children.

In this study, we report the insertion sequence IS Ppu 21 in the opr D porin gene of carbapenem-resistant Pseudomonas aeruginosa isolates from burn patients in Tehran, Iran. Antibiotic susceptibility tests for P. aeruginosa isolates were determined. Production of metallo-β-lactamases (MBLs) and carbapenemase was evaluated and the β-lactamase-encoding and aminoglycoside-modifying enzyme genes were investigated by PCR and sequencing methods. The mRNA transcription level of oprD and mex efflux pump genes were evaluated by real-time PCR. The outer membrane protein profile was determined by SDS-PAGE. The genetic relationship between the P. aeruginosa isolates was assessed by random amplified polymorphic DNA PCR. In all, 10.52% (10/95) of clinical isolates of P. aeruginosa harboured the IS Ppu 21 insertion element in the opr D gene. The extended-spectrum β-lactamase-encoding gene in IS Ppu 21-carrying isolates was bla TEM . PCR assays targeting MBL and carbapenemase-encoding genes were also negative in all ten isolates. The rmt A, aad A, aad B and arm A genes were positive in all IS Ppu 21 harbouring isolates. The relative expression levels of the mex X, mex B, mex T and mex D genes in ten isolates ranged from 0.1- to 1.4-fold, 1.1- to 3.68-fold, 0.3- to 8.22-fold and 1.7- to 35.17-fold, respectively. The relative expression levels of the oprD in ten isolates ranged from 0.57- to 35.01-fold, which was much higher than those in the control strain P. aeruginosa PAO1. Evaluation of the outer membrane protein by SDS-PAGE suggested that opr D was produced at very low levels by all isolates. Using random amplified polymorphic DNA PCR genotyping, eight of the ten isolates containing IS Ppu 21 were shown to be clonally related. The present study describes a novel molecular mechanism, IS Ppu 21 insertion of the opr D gene, associated with carbapenem resistance in clinical P. aeruginosa isolates.

Background: Demodicosis is one of the most prevalent skin diseases resulting from infestation by Demodex mites. This parasite usually inhabits in follicular infundibulum or sebaceous duct and transmits through close contact with an infested host. Methods: This study was carried from September 2014 to January 2016 at Tehran University of Medical Sciences, Tehran, Iran. DNA extraction and amplification of 16S ribosomal RNA was performed on four isolates, already obtained from four different patients and identified morphologically though clearing with 10% Potassium hydroxide (KOH) and microscopical examination. Amplified fragments from the isolates were compared with GeneBank database and phylogenetic analysis was carried out using MEGA6 software. Results: A 390 bp fragment of 16S rDNA was obtained in all isolates and analysis of generated sequences showed high similarity with those submitted to GenBank, previously. Intra-species similarity and distance also showed 99.983% and 0.017, respectively, for the studied isolates. Multiple alignments of the isolates showed Single Nucleotide Polymorphisms (SNPs) in 16S rRNA fragment. Phylogenetic analysis revealed that all 4 isolates clustered with other D. folliculorum, recovered from GenBank database. Our accession numbers KF875587 and KF875589 showed more similarity together in comparison with two other studied isolates. Conclusion: Mitochondrial 16S rDNA is one of the most suitable molecular barcodes for identification D. folliculorum and this fragment can use for intra-species characterization of the most human-infected mites.

Given that happiness is an important construct to enable adolescents to cope better with difficulties and stress of life, it is necessary to advance our knowledge about the possible etiology of happiness in adolescents. The present study sought to investigate the relationships of emotional intelligence, depressive symptoms, and happiness in a sample of male students in Tehran, Iran. This cross-sectional study was conducted on a sample of high school students in Tehran in 2012. The participants comprised of 188 male students (aged 16 to 19 years old) selected by multi-stage cluster sampling method. For gathering the data, the students filled out assessing emotions scale, Beck depression inventory-II, and Oxford happiness inventory. Data analysis was carried out using descriptive and analytical statistics in statistical package for social sciences (SPSS) software. The findings showed that a significant positive association existed between high ability of emotional intelligence and happiness (P < 0.01). Conversely, the low ability of emotional intelligence was associated with unhappiness (P < 0.01), there was a positive association between non-depression symptoms and happiness (P < 0.05), and severe depressive symptoms were positively associated with unhappiness (P < 0.01). High ability of emotional intelligence (P < 0.01) and non-depression symptoms (P < 0.05) were the strongest predictors of happiness. These findings reinforced the importance of emotional intelligence as a facilitating factor for happiness in adolescences. In addition, the findings suggested that depression symptoms may be harmful for happiness in adolescents.

Risk of developing type 2 diabetes is increased in women with previous gestational diabetes mellitus (GDM). Postpartum glycemic screening is recommended in women with recent GDM. But this screening rate is low and the reasons are unclear. The aim of this study was to explore the experiences of Iranian women with recent GDM on barriers of postpartum screening for diabetes. This qualitative study was conducted in Tehran, Iran in 2016. Semi-structured interview was used for data collection. 22 women with recent GDM were interviewed. These women gave birth in Tehran hospitals at a minimum of 6 months before interview. The missed screening defined as not attending to laboratory for Fasting Blood Sugar and/or Oral Glucose Tolerance Test, 6 week to 6 month after their child birthing. The data was analyzed by content analysis method. Themes and sub-themes that illustrated the barriers to postpartum diabetes screening were: inadequate education (about developing diabetes in the future, implementation of the screening, and glucometer validity in diagnosis of diabetes), perceiving the screening as difficult (feeling comfortable with the glucometer, poor laboratory conditions, issues related to the baby/babies, and financial problems), improper attitudes toward the screening (unwilling to get diagnosed, not giving priority to oneself, having false beliefs) and procrastination (gap to intention and action, self-deception and self-regulation failure). Women with recent GDM reported several barriers for postpartum diabetes screening. This study help to develop the evidence-based interventions for improving this screening rate.

Objectives: Aluminium phosphide (AlP) is a fumigant pesticide which protects stored grains from insects and rodents. When it comes into contact with moisture, AlP releases phosphine (PH3), a highly toxic gas. No efficient antidote has been found for AlP poisoning so far and most people who are poisoned do not survive. Boric acid is a Lewis acid with an empty p orbital which accepts electrons. This study aimed to investigate the neutralisation of PH3 gas with boric acid. Methods: This study was carried out at the Baharlou Hospital, Tehran University of Medical Sciences, Tehran, Iran, between December 2013 and February 2014. The volume of released gas, rate of gas evolution and changes in pH were measured during reactions of AlP tablets with water, acidified water, saturated boric acid solution, acidified saturated boric acid solution, activated charcoal and acidified activated charcoal. Infrared spectroscopy was used to study the resulting probable adduct between PH3 and boric acid. Results: Activated charcoal significantly reduced the volume of released gas (P <0.01). Although boric acid did not significantly reduce the volume of released gas, it significantly reduced the rate of gas evolution (P <0.01). A gaseous adduct was formed in the reaction between pure AlP and boric acid. Conclusion: These findings indicate that boric acid may be an efficient and non-toxic antidote for PH3 poisoning.

Objectives: This study aimed to assess and compare the perception of laypersons and dental professionals of smile esthetics based on two factors namely gingival display and alignment of teeth. Materials and Methods: A total of 32 females were randomly selected among dental students in the International Campus of School of Dentistry, Tehran University of Medical Sciences (Tehran, Iran) with no previous history of esthetic dental work. Frontal photographs were obtained and cropped from the subnasal to menton areas of subjects to standardize the size of pictures. Three series of slides were prepared of the pictures using Microsoft PowerPoint software. The first series of slides were shown to familiarize the observers with the images. The second and third series were displayed for the observers and they were then asked to fill out a questionnaire. The group of observers included 10 dental specialists and 10 laypersons. Each observer was given a visual analog scale (VAS) chart for scoring (1–10). After completion of the questionnaires, data were transferred to a computer and the differences in judgments of professionals and laypeople were analyzed using the Mann Whitney test. Results: No significant difference was found in the judgments of professionals and laypeople on evaluating overall smile esthetics, gingival display and alignment of teeth except for the slide showing a reverse smile arc. Conclusions: Laypeople and professionals had similar perceptions of smile esthetics. Thus, it appears that clinicians can rely on the judgment of laypersons in esthetic dental treatments.

Organizational Citizenship Behavior (OCB) is defined as "individual behavior that is discretionary, not directly or explicitly recognized by the formal reward system, and that in the aggregate, promotes the effective functioning of organization". OCB, enhance job satisfaction among nursing employees. According to several findings, nurses' OCB have a positive and significant influence on job satisfaction. This research is aimed to study OCB among Iranian nurses. A cross-sectional, descriptive and analytical study was conducted among 510 nurses working in 15 teaching hospitals in Tehran, Iran to be selected by stratified random sampling. The respondents were asked to complete Netemeyer's organizational citizenship behavior questionnaire that encompassed four dimensions of OCB including Sportsmanship, Civil Virtue, Conscientiousness, Altruism and selected each item of OCB dimensions and identified their attitudes about OCB items were observed in hospitals of Tehran. The data was analyzed by T-test, ANOVA and Pearson statistical methods. The results of this research showed that most of the nurses who studied in this study, had OCB behaviors. Also, we found that there was significant correlation between Iranian nurses' marriage status, qualifications and gender with sportsmanship, altruism and civic virtue. This research demonstrates the existence of OCB among Iranian nurses that are essential in developing patient - oriented behavior. The results can be used to develop further nursing management strategies for enhancement of OCB. Finally, the present study indicates new possibilities for future researches such as analysis and comparison of OCB between different hospitals and how nursing policy-makers can enhance these behaviors in Iranian hospitals.

The trust is meant the belief of the patient to the practitioner or the hospital based on the concept that the care provider seeks the best for the patient and will provide the suitable care and treatment for him/her. One of the main determinants of patient's trust is the service quality. This study aimed to examine the effect of quality of services provided in private hospitals on the patient's trust. In this descriptive cross-sectional study, 969 patients were selected using the consecutive method from eight private general hospitals of Tehran, Iran, in 2010. Data were collected through a questionnaire containing 20 items (14 items for quality, 6 items for trust) and its validity and reliability were confirmed. Data were analyzed using descriptive statistics and multivariate regression. The mean score of patients' perception of trust was 3.80 and 4.01 for service quality. Approximately 38% of the variance in patient trust was explained by service quality dimensions. Quality of interaction and process (P < 0.001) were the strongest factors in predicting patient's trust, but the quality of the environment had no significant effect on the patients' degree of trust. The interaction quality and process quality were the key determinants of patient's trust in the private hospitals of Tehran. To enhance the patients' trust, quality improvement efforts should focus on service delivery aspects such as scheduling, timely and accurate doing of the service, and strengthening the interpersonal aspects of care and communication skills of doctors, nurses and staff.

Hospital waste materials pose a wide variety of health and safety hazards for patients and healthcare workers. Many of hospitals in Iran have neither a satisfactory waste disposal system nor a waste management and disposal policy. The main objective of this research was to investigate the solid waste management in the eight teaching hospitals of Iran University of Medical Sciences. In this cross-sectional study, the main stages of hospital waste management including generation, separation, collection, storage, and disposal of waste materials were assessed in these hospitals, located in Tehran city. The measurement was conducted through a questionnaire and direct observation by researchers. The data obtained was converted to a quantitative measure to evaluate the different management components. The results showed that the waste generation rate was 2.5 to 3.01 kg bed(-1) day(-1), which included 85 to 90% of domestic waste and 10 to 15% of infectious waste. The lack of separation between hazardous and non-hazardous waste, an absence of the necessary rules and regulations applying to the collection of waste from hospital wards and on-site transport to a temporary storage location, a lack of proper waste treatment, and disposal of hospital waste along with municipal garbage, were the main findings. In order to improve the existing conditions, some extensive research to assess the present situation in the hospitals of Iran, the compilation of rules and establishment of standards and effective training for the personnel are actions that are recommended.

Background: Hepatitis B infection is still the main cause of chronic liver disease in Iran, which is associated with significant economic and social costs. Objectives: This study aimed to estimate the financial burden caused by CHB infection and its complications in Iran. Patients and Methods: Prevalence-based and bottom-up approaches were used to collect the data. Data on direct medical costs were extracted from outpatient medical records in a referral gastroenterology and hepatology research center, inpatient medical records in several major hospitals in Tehran and Shiraz in 2013, and the self-reports of specialists. Data on direct non-medical and indirect costs were collected based on the patients’ self-reports through face-to-face interviews performed in the mentioned centers. To calculate the indirect costs, friction cost approach was used. To calculate the total cost-of-illness in Iran, the total cost per patient at each stage of the disease was estimated and multiplied by the total number of patients. Results: The total annual cost for the activate population of CHB patients and for those receiving treatment at various disease stages were respectively 450 million and 226 million dollars, with 64% and 70% of which allocated to direct costs respectively, and 36% and 30% to indirect costs respectively. The total direct costs alone for each group were respectively 1.17% and 0.6% of the total health expenditure. Furthermore, the cost spent on drugs encompasses the largest proportion of the direct medical cost for all stages of the disease. Conclusions: According to the perspectives of payers, patients, and community, CHB infection can be considered as one of the diseases with a substantial economic burden; the disease, specifically in extreme cases, can be too expensive and costly for patients. Therefore, patients should be protected against more severe stages of the disease through proper treatment and early diagnosis. PMID:25977694

Skin cancer is one of the most common cancers worldwide, including in Iran. Variations in its incidence rate among geographical areas are due to various contributing factors. Since there has been a lack of studies on this topic in our country, the present spatial analysis of skin cancer incidence in Iran in 2009 was conducted using data from the cancer registry system for the country. The reported incidences of the disease were standardized on the basis of the World Health Organization population and the direct method. Then the data were inserted into the GIS software, and finally, using the analysis of hot spots (Getis-Ord Gi), high-risk areas were drawn. Provinces that were 1.9 SD higher or lower than the national average were considered hot spots or cold spots, with significance at the level of 0.05. In 2009, a total of 9,964 cases of skin cancer occurred, 3,696 in women and 6,268 in men (standardized incidence rates of 15.8 and 22.6, respectively). The results of the study showed that in men and women, the disease demonstrated high incidence in the central provinces and desert regions. In women, Yazd Province and in men, Qom Province had significant hot spots (p =0.05). While Isfahan, Markazi, Tehran and Kurdistan provinces were expected to be hot spots, the differences from the national average were not significant at the 0.05 level. As well, the provinces of Sistan Va Baluchistan, Kerman, and Hormozgan were identified as cold or low-risk disease regions (p <0.05). The central provinces of the country due to hot weather conditions, more solar radiation, and closer vicinity to the central desert of Iran demonstrated higher incidence rates for skin cancer, so further epidemiological studies into the etiology and early detection are essential in these areas.

The Crust and Upper Mantle Structure of the Iranian Plateau from Joint Waveform Tomography Imaging of Body and Surface Waves

The Iranian Plateau forms a broad zone of deformation between the colliding Arabian and Eurasian plates. The convergence is accommodated in the Zagros Mountains of SW Iran, the Alborz Mountains of northern Iran, and the Kopeh Dagh Mountains of NE Iran. These deforming belts are separated by relatively aseismic depressions such as the Lut Block. It has been suggested that the Arabia-Eurasia collision is similar to the Indo-Eurasia collision but at a early point of development and therefore, it may provide clues to our understanding of the earlier stages of the continent-continent collision process. We present results of the analysis of seismic data collected along two NE-SW trending transects across the Iranian Plateau. The first profile extends from near Bushere on the Persian Gulf coast to near to the Iran-Turkmenistan border north of Mashad, and consists of seismic recordings along the SW portion of the line in 2000-2001 and recording along the NE portion of the line in 2003 and 2006-2008. The second profile extends from near the Iran-Iraq border near the Dezfel embayment to the south Caspian Sea coast north of Tehran. We apply the combined 2.5D finite element waveform tomography algorithm of Baker and Roecker [2014] to jointly invert teleseismic body and surface waves to determine the elastic wavespeed structures of these areas. The joint inversion of these different types of waves affords similar types of advantages that are common to combined surface wave dispersion/receiver function inversions in compensating for intrinsic weaknesses in horizontal and vertical resolution capabilities. We compare results recovered from a finite difference approach to document the effects of various assumptions related to their application, such as the inclusion of topography, on the models recovered. We also apply several different inverse methods, starting with simple gradient techniques to the more sophisticated pseudo-Hessian or L-BFGS approach, and find that the latter are generally more robust. Modeling of receiver functions and surface wave dispersion prior to the analysis is shown to be an efficacious way to generate starting models for this analysis.

Risk factors for colonization with vancomycin-resistant enterococci (VRE) vary by population and locale. The objective of this study was to determine the prevalence of and risk factors for VRE colonization in children with acute lymphoblastic leukemia (ALL) in Tehran. Stools were collected from children with ALL at the Ali Asghar Children's Hospital and the Mahak Pediatric Oncology Center between March 2007 and October 2008. Demographic features and potential risk factors for VRE colonization, including duration of ALL, presence of severe neutropenia in the preceding month, receipt of antibiotics in the preceding 3 months, concurrent medical problems, days of hospitalization, and the need for intensive care since the time of diagnosis of ALL, were recorded. VRE was identified from stools in 33 of 130 children with ALL (25%). No clear risk factors were identified for VRE colonization in the current study, but there was a trend towards an increased prevalence in children admitted to the intensive care unit since their ALL diagnosis (p=0.07). The VanA genotype was found in 28 of the 33 stools (85%), with all other enterococci being VanB. The prevalence of VRE colonization in children with ALL in Tehran is high. Modifiable risk factors have not been identified. The implementation of routine surveillance for colonization and an increased emphasis on adherence to standard infection control precautions may prevent spread.

Service quality is perceived as an important factor for developing patient's loyalty. The aim of this study was to determine the hospital service quality from the patients' viewpoints and the relative importance of quality dimensions in predicting the patient's loyalty. A cross-sectional study was conducted in 2010. The study sample was composed of 943 patients selected from eight private general hospitals in Tehran. The survey instrument was a questionnaire included 24 items about the service quality and 3 items about the patient's loyalty. Exploratory factor analysis was employed to extracting the dimensions of service quality. Also, regression analysis was performed to determining the relative importance of the service quality dimensions in predicting the patient's loyalty. The mean score of service quality and patient's loyalty was 3.99 and 4.16 out of 5, respectively. About 29% of the loyalty variance was explained by the service quality dimensions. Four quality dimensions (Costing, Process Quality, Interaction Quality and Environment Quality) were found to be key determinants of the patient's loyalty in the private hospitals of Tehran. The patients' experience in relation to the private hospitals' services has strong impact on the outcome variables like willingness to return to the same hospital and reuse its services or recommend them to others. The relationship between the service quality and patient's loyalty proves the strategic importance of improving the service quality for dragging and retaining patients and expanding the market share.

Ramadan fasting is associated with some lifestyle changes. A lack of nutritional needs knowledge or the improper performance of fasting, particularly in relation to time, type and amount of food intake, can cause disorders such as indigestion, bloating, constipation, headaches and other clinical problems. To investigate the general knowledge regarding dietary factors associated with Ramadan fasting and its related complications. This prospective, non-interventional, observational study was conducted from April to July, 2012 to coincide with the month before and the month of Ramadan. The initial participants were 600 fasting and 588 non-fasting people (aged 18 - 65 years, BMI 18.5 - 40 kg/m 2 ) chosen by random cluster sampling in Tehran, Iran. A questionnaire of Ramadan fasting nutritional knowledge was developed and validated in a pilot study. The Likert scale was used two weeks before Ramadan and during the third and fourth weeks of Ramadan to estimate Ramadan-related complications. Seven-day, 24 - hour food recalls were used to assess food intakes. The lowest level of general knowledge was identified in the context of foods associated with hunger (22.1%) and hypoglycemia (24.8%) and the highest level of general knowledge was identified in reference to unsuitable foods for Sahar (91.4%). During Ramadan, all attributed complications increased in fasting subjects (P < 0.001). High calorie, carbohydrate, fat and protein intakes in the Ramadan diet were associated with some gastrointestinal and sleep complications (P < 0.05). Despite the relatively high level of knowledge in the context of the general principles of a diet to prevent Ramadan-related complications, practical training in regard to the amounts of nutrients associated with Ramadan-related complications is both necessary and recommended.

As plantations become increasingly important sources of wood and fiber in arid/semiarid places, they have also become increasingly criticized for their hydrological impacts. An examination and comparison of gross rainfall (GR) partitioning across commonly-planted tree species (Pinus eldarica, Cupressus arizonica, Robinia pseudoacacia, and Fraxinus rotundifolia) in semiarid regions has great value for watershed and forest managers interested in managing canopy hydrological processes for societal benefit. Therefore, we performed a field study examining GR partitioning into throughfall (TF), stemflow (SF), and rainfall interception (I) for these species in the semiarid Chitgar Forest Park, Tehran, Iran. An advantage to our study is that we explore the effects of forest structural differences in plantation forests experiencing similar climatic factors and storm conditions. As such, variability in GR partitioning due to different meteorological conditions is minimized, allowing comparison of structural attributes across plantations. Our results show that commonly-selected afforestation species experiencing the same climate produced differing stand structures that differentially partition GR into TF, SF, and I. P. eldarica might be the best of the four species to plant if the primary goal of afforestation is to limit erosion and stormwater runoff as it intercepted more rainfall than other species. However, the high SF generation from F. rotundifolia, and low GR necessary to initiate SF, could maximize retention of water in the soils since SF has been shown to infiltrate along root pathways and access groundwater. A consideration of GR partitioning should be considered when selecting a species for afforestation/reforestation in water-limited ecosystems. Copyright © 2016 Elsevier B.V. All rights reserved.

To describe long-term outcomes and complications of Ahmed glaucoma valve (AGV) implantation in subjects with refractory glaucoma at Farabi Eye Hospital, Tehran, Iran. This retrospective cohort study evaluated patient records of all subjects with refractory glaucoma who had undergone AGV implantation up to January 2013. The main outcome measure was the surgical success rate. Complete success was defined as intraocular pressure (IOP) <22 mmHg, without anti-glaucoma medications or additional surgery. Qualified success was IOP <22 mmHg regardless of number of anti-glaucoma medications. In all cases, loss of vision (no light perception) was considered an independent indicator of failure. Data were also collected on intraoperative and postoperative complications. Twenty-eight eyes were included in the study. With a mean follow-up of 48.2 ± 31.7 months (median: 40.50 months; range: 3-124 months), the IOP decreased from a mean preoperative value of 30.8 ± 5.6 mmHg to 20.0 ± 6.4 mmHg at last visit. The number of medications decreased from 3.7 ± 0.4 preoperatively to 2.5 ± 1.1 postoperatively. Cumulative qualified success was achieved in 69% of eyes. Mean time to failure according to qualified success criteria was 92.3 ± 9.4 months. Postoperative complications were recorded in 16 (57.1%) eyes. The most common complication was focal endothelial corneal decompensation at the site of tube-cornea touch. AGV implantation with adjunctive topical anti-glaucoma drops controlled IOP in approximately 70% of eyes with refractory glaucoma with a median of 40.5 months of follow-up. However, complication rates were higher.

Stainless steel orthodontic brackets can release metal ions into the saliva. Fluoridated mouthwashes are often recommended to orthodontic patients to reduce the risk of white-spot lesions around their brackets. However, little information is available regarding the effect of different mouthwashes in ion release of orthodontic brackets. The purpose of this study was to measure the amount of metal ion release from orthodontic brackets when kept in different mouthwashes. One hundred sixty stainless steel brackets (0.022-in, 3M Unitek, Monrovia, Calif) were divided randomly into 4 equal groups and immersed in Oral B (Procter & Gamble, Weybridge, United Kingdom), chlorhexidine (Shahdaru Labratories, Tehran, Iran), and Persica (Poursina Pharmaceutical Laboratories, Tehran, Iran) mouthwashes and distilled deionized water and incubated at 37°C for 45 days. Nickel, chromium, iron, copper, and manganese released from the orthodontic brackets were measured with an inductively coupled plasma spectrometer. For statistical analysis, 1-way analysis of variance (ANOVA) and the Duncan multiple-range tests were used. The results showed that ion release in deionized water was significantly (P <0.05) higher than in the 3 mouthwashes. Higher ion release was found with chlorhexidine compared with the other 2 mouthwashes. There was no significant difference (P >0.05) in nickel, chromium, iron, and copper ion release in the Oral B and Persica mouthwashes. The level of manganese release was significantly different in all 4 groups. If ion release is a concern, Oral B and Persica mouthwashes might be better options than chlorhexidine for orthodontic patients with stainless steel brackets.

Physicians' knowledge of therapy and counseling stands among the most important issues in the viewpoints of clients who refer to psychiatric centers. Transsexual patients are very important in this regard. The goal of this research is to study their attitude toward doctors' empathy. A group of transsexual patients who referred to the Tehran Institute of Psychiatry, Iran, answered the Jefferson Scale of Empathy. The relationship of the patients' age, gender, education level, and lifestyle with their attitude was measured. This study was conducted on 40 patients, including 16 women (40%) and 24 men (60%). In terms of education, 8 patients had a degree below high school diploma (20%), 9 had high school diploma (22.5%), and 23 patients were university students or of higher education level (57.5%). Among these patients, 6 were unemployed (15%), 10 were students (25%), and the rest were employed. Moreover, 8 participants lived alone (20%), 5 lived with their friends (12.5%), and 27 lived with their family (67.5%). Gender had no influence on the average score of the questionnaires, yet level of education had some influence. Lifestyle also had a significant influence on the patients' attitude. On the other hand, patients whose problems began before the age of 12 had lower score than others. Experienced psychologists in referential centers can express greater levels of empathy to specific diseases and this trend is very effective on the patients' cooperation level. In order to create an effective relationship between physicians and patients, the efficiency of the health system and increasing satisfaction of specific patients should be considered.

We aimed to compare the medical students' attitude towards psychiatry before and after psychiatry clerkship, and to examine the association of choosing psychiatry as a future career with some personal characteristics. In a self-controlled, quasi-experimental study, all of the medical students entering the psychiatry clerkship in three major medical schools of Iran located in Tehran (Tehran, Shahid Beheshti, and Iran University of Medical Sciences) were asked to participate anonymously in the study on the first and the last 3-days of their psychiatry clerkship. From 346 invited 4th-5th year medical students, 225 (65%) completed anonymous self-report questionnaires before and after a 4-week psychiatry clerkship. Positive response to choose psychiatry as a career was seen in 13.3% and 18.3% before and after psychiatry rotation, respectively. However, the difference was not statistically significant; about one-quarter of the students were turned on to psychiatry and 25% were discouraged during the clerkship. Individual pair wise comparisons revealed significant improvements only in two out of 13 measured aspects of psychiatry. Seventeen out of 38 (47.7%) students who identified psychiatry as the career of choice or strong possibility reported that one of their family members or close friends' mental illness had an impact on their choice. Those students who considered psychiatry as the strong possibility claimed that they are more interested in humanities (OR = 2.96; 95% CI: 1.17, 7.49), and playing a musical instrument (OR = 2.53; 95% CI: 1.15, 5.57). It may be concluded that exposure to psychiatry clerkship could influence medical students' opinion about psychiatry positively, or negatively. Personal characteristics and individual interests of students may play an important role in choosing psychiatry as their future career.

Colorectal cancer is the third and fourth leading cause of cancer incidence and mortality among men and women, respectively in Iran. However, the role of dietary factors that could contribute to this high cancer incidence remains unclear. The aim of this study was to determine major dietary patterns and its relationship with colorectal cancer. This case-control study was conducted in four hospitals in Tehran city of Iran. A total of 71 patients (35 men and 36 women, aged 40-75 years) with incident clinically confirmed colorectal cancer (CRC) and 142 controls (70 men and 72 women, aged 40-75 years) admitted to hospital for acute, non-neoplastic diseases were recruited and interviewed. Dietary data were assessed by 125-item semi-quantitative food frequency questionnaire. Multivariate logistic regression was used to estimate the relationship between dietary patterns and risk of colorectal cancer. Two major dietary patterns (Healthy pattern and Western pattern) were derived using principal component analysis. Each dietary pattern explained 11.9% (Healthy pattern) and 10.3% (Western pattern) of the variation in food intake, respectively. After adjusting for confounding factors, the Healthy dietary pattern was significantly associated with a decreased risk of colorectal cancer (OR= 0.227; 95% CI=0.108-0.478) while an increased risk of colorectal cancer was observed with the Western dietary pattern (OR=2.616; 95% CI= 1.361-5.030). Specific dietary patterns, which include healthy and western patterns, may be associated with the risk of colorectal cancer. This diet-disease relationship can be used for developing interventions that aim to promote healthy eating for the prevention of chronic disease, particularly colorectal cancer in the Iranian population.

Hearing loss can affect the perception of emotional reaction to the music. The present study investigated whether the students with congenital hearing loss exposed to the deaf culture, percept the same emotion from the music as students with acquired hearing loss. Participants were divided into two groups; 30 students with bilaterally congenital moderate to severe hearing loss that were selected from deaf schools located in Tehran, Iran and 30 students with an acquired hearing loss with the same degree of hearing loss selected from Amiralam Hospital, Tehran, Iran and compared with the group of 30 age and gender-matched normal hearing subjects served our control in 2012. The musical stimuli consisted of three different sequences of music, (sadness, happiness, and fear) each with the duration of 60 sec. The students were asked to point to the lists of words that best matched with their emotions. Emotional perception of sadness, happiness, and fear in congenital hearing loss children was significantly poorly than acquired hearing loss and normal hearing group ( P <0.001). There was no significant difference in the emotional perception of sadness, happiness, and fear among the group of acquired hearing loss and normal hearing group ( P =0.75), ( P =1) and ( P =0.16) respectively. Neural plasticity induced by hearing assistant devises may be affected by the time when a hearing aid was first fitted and how the auditory system responds to the reintroduction of certain sounds via amplification. Therefore, children who experienced auditory input of different sound patterns in their early childhood will show more perceptual flexibility in different situations than the children with congenital hearing loss and Deaf culture.

Descriptive cross-sectional study. To investigate the relationship between perceived social support and depression and to evaluate the role of family, friends and other caregivers in the perception of social support in Iranian individuals with spinal cord injury (SCI). Brain and Spinal Cord Injury Research Center, Tehran University of Medical Sciences, Tehran, Iran. Social support was evaluated using the Multidimensional Scale of Perceived Social Support questionnaire, which gauges perceptions of support from family, friends and 'important persons'. The presence and severity of depression were assessed with the Beck Depression Inventory (BDI-II-PERSIAN)-a 21-item multiple-choice questionnaire. A total of 140 individuals with SCI were enrolled in the study. The average age of the participants was 29.4±7.9 years; the mean duration of injury was 46.3±46.5 months and most patients were male (72%). Social support and all subscales of social support were numerically greater in males; however, this difference was not statistically significant. The subcategory of friends' support in men was 17.9±7.9 compared to 14.6±8.0 in women (P=0.04). The self-reported social support score (r=-0.387, P<0.001) and subscales of social support, including family (r=-0.174, P=0.045), friends (r=-0.356, P<0.001) and important persons (r=-0.373, P<0.001), were all negatively correlated with depression. Higher self-reported perception of social support appears to be associated with lower levels of depression in individuals with SCI. SCI care providers should consider the relationship between social support and depression in their continuing care.

Urban growth phenomenon as a spatio-temporal continuous process is subject to spatial uncertainty. This inherent uncertainty cannot be fully addressed by the conventional methods based on the Boolean algebra. Fuzzy logic can be employed to overcome this limitation. Fuzzy logic preserves the continuity of dynamic urban growth spatially by choosing fuzzy membership functions, fuzzy rules and the fuzzification-defuzzification process. Fuzzy membership functions and fuzzy rule sets as the heart of fuzzy logic are rather subjective and dependent on the expert. However, due to lack of a definite method for determining the membership function parameters, certain optimization is needed to tune the parameters and improve the performance of the model. This paper integrates genetic algorithms and fuzzy logic as a genetic fuzzy system (GFS) for modeling dynamic urban growth. The proposed approach is applied for modeling urban growth in Tehran Metropolitan Area in Iran. Historical land use/cover data of Tehran Metropolitan Area extracted from the 1988 and 1999 Landsat ETM+ images are employed in order to simulate the urban growth. The extracted land use classes of the year 1988 include urban areas, street, vegetation areas, slope and elevation used as urban growth physical driving forces. Relative Operating Characteristic (ROC) curve as an fitness function has been used to evaluate the performance of the GFS algorithm. The optimum membership function parameter is applied for generating a suitability map for the urban growth. Comparing the suitability map and real land use map of 1999 gives the threshold value for the best suitability map which can simulate the land use map of 1999. The simulation outcomes in terms of kappa of 89.13% and overall map accuracy of 95.58% demonstrated the efficiency and reliability of the proposed model.

Introduction Human resources are the most strategic resource and the most significant input for health systems. Their behavior and motivation can strongly affect the overall performance of the health systems. The aim of this study was to determine the factors that affect motivation in frontline employees at teaching hospitals affiliated with Shahid Beheshti University of Medical Sciences (SBMU) in Tehran, Iran. Methods This cross-sectional study was conducted in 2015. The participants (nurses, physiotherapists, radiology and laboratory technicians, operating room and pharmacy staff) were 300 employees selected by the stratified random sampling method from two general and teaching hospitals. The data collection instrument was a questionnaire that consisted of 42 questions in the 7 domains of motivational factors. Data analysis was performed using descriptive statistics and independent samples t-test by SPSS software, version 23. Results The findings indicated that working relationships (mean of 3.95) were the main determinant of job motivation of frontline employees. Job content (3.76) career development (3.75), social respect (3.75), and autonomy (3.30) were the next four affective factors. Recognition and remuneration had the least influence on the job motivation of frontline employees. The results of the Friedman test indicated that the difference between the mean scores of different dimensions was significant (χ2(6) = 607.00, p < 0.001). Conclusion A hospital that seeks to engender increased motivation of its frontline employees should have in place a human resources strategy that includes facilitating communication between personnel and management, supporting employees in the community, and promoting social respect for health professions, providing educational opportunities and career development, development of appropriate promotional policies, employee participation in goal setting, facilitating a good working environment and job security, job enrichment, and delegation.

According to latest available data there are more of 300,000 people injects drug users (PWID) in Iran. In this study, we used a Blinder-Oaxaca (BO) decomposition to explore the relative contributions of inequality in utilization of NSPs and to decompose it to its determinants in Teheran. We used data from a cross-sectional survey using snowball sampling to recruit 500 PWID from June to July 2016 in Tehran. Participants were reported injecting drug use in the past month, were able to speak and comprehend Farsi enough to respond to survey questions, and were able to provide informed consent to complete the interview. We used a BO method to decompose the role of economic inequality on utilization of needle and syringe programs. A total 520 of clients participated in the study of which data was fully complete for 500. The selected predictor variables (age, education level, marital status, homelessness, HIV risk perception, and HIV knowledge) together explain 54% (8.5% out of 16%) of total inequality in utilization of needle and syringe programs and the remaining 46% constitute the unexplained residual. HIV risk perception status contributed about 38% (3.3% out of 8.5%) to the total health inequality, followed by HIV knowledge (26%) and education level were contributed 20% each, respectively. The results showed that contribution of economic inequalities in utilization of NSPs was primarily explained by the differential effects of HIV risk perception and HIV knowledge among PWID. Reducing HIV risk perception and increasing HIV knowledge might be essential to efforts to eliminate inequalities in access to NSPs among PWID.

Objective To determine the radioprotective effects of Silymarin in adult male Sprague-Dawley rats irradiated with γ-rays. Methods The present experimental study was performed in Tehran University of Medical Sciences, Tehran, Iran from December 2009 to March 2010. The study was performed on 40 rats, which were randomly and equally divided into four groups: 1) control group: neither received Silymarin nor irradiated with γ-rays; 2) γ-irradiation group: testis region exposed to 2Gy of γ-rays; 3) Silymarin & γ-irradiation: rats received 100 mg/kg of Silymarin 24hrs before exposure to 2Gy of γ-rays; 4) Silymarin & γ-irradiation: rats received 200 mg/kg of Silymarin 24hrs before exposure to 2Gy of γ-rays. After animal experiments and preparing the tissue sections, different histological and histomorphological parameters of seminiferous tubules and the biological characteristics of Leydig cells were evaluated applying quantitative assessment, Johnson scoring, and Leydig cell apoptosis assay by TUNEL method. The data were analyzed applying ANOVA and Tukey’s post hoc test, using SPSS software (V.19). Results Irradiation of 2 Gy γ-rays to the testis of the rats significantly affected the frequency of spermatogonia, primary spermatocyte, round spermatid, spermatozoa, seminiferous tube and lumen diameters, thickness of the epithelium, Leydig cell nuclear diameter and volume, epithelium height, and apoptotic cells (p<0.05). However, administration of Silymarin improved the mentioned parameters specifically in 200 mg/kg of dosage. Conclusion Silymarin could act as a potent radioprotector and it can be used in modulation as well as improvement to radiation therapy to prevent male reproductive function, specifically seminiferous tubules in an animal model; however, its molecular mechanism is still not clear and needs more molecular researches.

Recent studies using molecular epidemiological techniques have demonstrated mixed infection with multiple strains of Mycobacterium tuberculosis especially in countries with high tuberculosis (TB) burden. We aimed to determine the prevalence of mixed infection among patients with TB in the capital of Iran as a country with moderate incidence rate. Samples were collected randomly from January 2011 to December 2013 in Tehran, capital of Iran. A total of 75 M. tuberculosis isolates were genotyped by 24 loci mycobacterial interspersed repetitive unit-variable number tandem repeat typing (MIRU-VNTR) for screening the mixed infection. Twenty patients (20/75) were identified with mixed infection, and the estimated rate of mixed infection was 26.6%. Thirteen out of the 24 loci were able to detect the mixed infection in our study. Mixed infections occur at high prevalence among studied Iranian TB patients. Further research is inevitable to evaluate the association of mixed infection and disease progression and treatment.

Abstract: Background: Public education is one of the most important elements of earthquake preparedness. The present study identifies methods and appropriate strategies for public awareness and education on preparedness for earthquakes based on people's opinions in the city of Tehran. Methods: This was a cross-sectional study and a door-to-door survey of residents from 22 municipal districts in Tehran, the capital city of Iran. It involved a total of 1 211 individuals aged 15 and above. People were asked about different methods of public information and education, as well as the type of information needed for earthquake preparedness. Results: "Enforcing the building contractors' compliance with the construction codes and regulations" was ranked as the first priority by 33.4% of the respondents. Over 70% of the participants (71.7%) regarded TV as the most appropriate means of media communication to prepare people for an earthquake. This was followed by "radio" which was selected by 51.6% of respondents. Slightly over 95% of the respondents believed that there would soon be an earthquake in the country, and 80% reported that they obtained this information from "the general public". Seventy percent of the study population felt that news of an earthquake should be communicated through the media. However, over fifty (58%) of the participants believed that governmental officials and agencies are best qualified to disseminate information about the risk of an imminent earthquake. Just over half (50.8%) of the respondents argued that the authorities do not usually provide enough information to people about earthquakes and the probability of their occurrence. Besides seismologists, respondents thought astronauts (32%), fortunetellers (32.3%), religious figures (34%), meteorologists (23%), and paleontologists (2%) can correctly predict the occurrence of an earthquake. Furthermore, 88.6% listed aid centers, mosques, newspapers and TV as the most important sources of information during the aftermath of an earthquake, Discussion: A participatory approach to earthquake-preparedness planning is recommended. This would ensure that program planners use methods, tools, media, and educational materials that are compatible with the culture, needs, and skills of the local communities. Conclusions: The findings of this study also reveal methods and tools that the local community considers to be most effective for earthquake-preparedness planning and management. The development of an earthquake-resistance and a safe community requires a high level of collaboration between broadcasting organizations, seismologists, experts in the disaster- preparedness field, as well as the local community. This will allow for timely planning, development, and dissemination of essential information to all stakeholders including the local communities. PMID:21483203

Abstract: Background: Road Traffic Injuries (RTIs) as a result of road traffic crashes (RTCs) rank as the leading cause of death, disability and property loss worldwide, especially in low and middle-income countries. This study aims to analyze the costs of RTCs in Iran. Methods: A standard human capital approach was used to estimate the costs. Costs included medical, administrative and funeral costs, property damage, production lost and intangible costs. Data about the number of deaths and injuries resulting from RTIs between 20 March 2009 and 20 March 2010 was obtained from two national databases designed at the Center for Disaster Management and Medical Emergencies (CDMME) and the Legal Medicine Organization (LMO), respectively. The severity and medical costs of injuries were identified by reviewing 400 medical records that were selected randomly from patients who were admitted to two large trauma centers in Shariati and Sina hospitals in Tehran province. Moreover, information about production lost, property damage, rehabilitation cost, intangible costs and administration costs were collected by review of current evidence and consulting with expert opinion. Results: In total 806,922 RTIs and 22,974 deaths resulted from the RTCs in the study period. The total cost of RTCs was about 72,465 billion Rials (7.2 billion US Dollars), which amounts to 2.19% of Iran’s Gross Domestic Production (GDP). Direct costs were 3,516 billion Rials (around 48.6 % of the total costs), following by 24,785 billion Rials (around 34.2 % of the total costs) for production lost and 12,513 billion Rials (around 17.2 % of the total costs) for intangible costs. Conclusions: This study indicated that the burden of both RTCs and RTIs in Iran is substantial. Moreover, RTCs have significant economic consequences and are a large drain on healthcare resources.

Abstract Background Surveillance of dermatophytosis is essential to determine the likely changes in etiological trends and distribution profile of this infection. In this study beta tubulin gene (BT2), was used as the first time in a PCR-RFLP format to clarify the distribution of dermatophytosis agents in some parts of Iran. Methods A total of 603 clinical isolates was obtained from 500 patients in Tehran, Isfahan, Mazandaran and Guilan provinces. The isolates were identified using macro/micro-morphological criteria and electrophoretic patterns of PCR amplicons of BT2after digestion with each of the restriction enzymes FatI, HpyCH4V, MwoI and Alw21I. Results Among the patients, 59.2% were male and 40.8% female. The most prevalent clinical form was tinea pedis (42.4%), followed by tinea cruris (24.2%), tinea unguium (12.3%), tinea corporis (10.8%), tinea faciei (4%), tinea manuum (3.14%), tinea capitis (3%) and tinea barbae (0.16%), respectively. Trichophyton interdigitale ranked the first, followed by T. rubrum, Epidermophyton floccosum, Microsporum canis, T. tonsurans, T. erinacei and T. violaceum (each 0.49%) and the less frequent species were T. schoenleinii, M. gypseum and T.anamorph of Arthroderma benhamiae (each 0.16%). A case of scalp infection by E. floccosum was an exceptional event in the study. No case of T. verrucosum was found. Conclusion Trichophyton species and E. floccosum are yet the predominant agents of infection in Iran, while Microsporum species are decreasing. T. interdigitale and Tinea pedis remain as the most causal agent and clinical form of dermatophytosis, respectively. It seems that BT2 can be a useful genetic marker for epidemiological survey of common pathogenic dermatophytes. PMID:26060667

Background In today’s transforming world, increased productivity and efficient use of existing facilities are practically beyond a choice and become a necessity. In this line, attention to change and transformation is one of the affecting factors on the growth of productivity in organizations, especially in hospitals. Aim To examine the effect of transformational leadership on the productivity of employees in teaching hospitals affiliated to Iran University of Medical Sciences. Methods This cross-sectional study was conducted on 254 participants from educational and medical centers affiliated to Iran University of Medical Sciences (Tehran, Iran) in 2016. The standard questionnaires of Bass & Avolio and of Hersi & Goldsmith were used to respectively assess transformational leadership and level of productivity. The research assumptions were tested in a significance level of 0.05 by applying descriptive statistics and structural equations modeling (SEM) using SPSS 19 and Amos 24. Results Results of the fitting indicators of the assessing model after amending includes Chi-square two to degrees of freedom of 2.756, CFI indicator 0.95, IFI indicator 0.92, Root mean square error of approximation (RMSEA) indicator 0.10. These results indicate that the assessing model is well fitting after the amendment. Also, analysis of the model’s assumptions and the final model of the research reveals the effect of transformational leadership on employees’ productivity with a significance level of 0.83 (p=0.001). Conclusion This research indicates that the more the leadership and decision-making style in hospitals lean towards transformational mode, the more positive outcomes it brings among employees and the organization due to increased productivity. Therefore, it is essential to pay focused attention to training/educational programs in organizations to create and encourage transformational leadership behaviors which hopefully lead to more productive employees.

OBJECTIVES The aim of this study was to measure the health-related quality of life (HRQoL) and to evaluate the factors affecting HRQoL in individuals with health insurance in Tehran, Iran. METHODS A cross-sectional analytical study was conducted using the 3-level EuroQol 5-dimensions (EQ-5D) questionnaire. In order to estimate the determinants of HRQoL, information about participants’ demographic, socioeconomic, and health status was gathered. The cluster sampling technique was used to collect data from May to June, 2016. The chi-square test and weighted least squares method were employed for data analysis. Data were analyzed using Stata version 11.0. RESULTS A total of 600 Iranians with insurance completed the study, of whom 327 (54.5%) were male and 273 (45.5%) were female. The mean age of the participants was 41.48 years (standard deviation [SD], 14.60 years). Meanwhile, the mean duration of education was 12.36 years (SD, 4.68 years). The mean EQ-5D score was 0.74 (SD, 0.16). The most common health problems in the participants were anxiety/depression (42.3%), followed by pain/discomfort (39.2%). Sex, age, years of schooling, income, chronic disease, and body mass index had a significant effect on HRQoL (p<0.05). Healthy insured individuals, on average, had a HRQoL score 0.119 higher than that of people with a chronic disease, all else being equal (p<0.001). CONCLUSIONS Among all determinants of HRQoL, chronic disease was found to be the highest priority for interventions to improve the health status of Iranians with insurance. This finding can help policymakers and health insurance organizations improve their planning to promote the HRQoL of individuals with insurance and society as a whole in Iran. PMID:27788567

2012-01-01

Background Opiates are the main drugs of abuse, and Methadone Maintenance Treatment (MMT) is the most widely administered drug addiction treatment program in Iran. Our study aimed to investigate patterns of pre-treatment drug abuse, addiction treatment history and characteristics of patients in MMT in Tehran. Methods We applied a stratified cluster random sampling technique and conducted a cross-sectional survey utilizing a standard patient characteristic and addiction history form with patients (n = 810) in MMT. The Chi-square test and t-test served for statistical analyses. Results A clear majority of the participants were men (96%), more than 60% of whom were between 25 and 44 years of age, educated (89% had more than elementary education), and employed (>70%). The most commonly reported main drugs of abuse prior to MMT entry were opium (69%) and crystalline heroin (24%). The patients’ lifetime drug experience included opium (92%), crystalline heroin (28%), cannabis (16%), amphetamines (15%), and other drugs (33%). Crystalline heroin abusers were younger than opium users, had begun abusing drugs earlier, and reported a shorter history of opiate addiction. Conclusion Opium and crystalline heroin were the main drugs of abuse. A high rate of addiction using more dangerous opiate drugs such as crystalline heroin calls for more preventive efforts, especially among young men. PMID:22676557

Domestic violence is the third sociopathology after addiction and child abuse in Iran. Fifty-six percent of Iranian women in the range of 17-32 years old are exposed to the highest domestic violence. Objective: The aim of this study was to design and psychoanalyze a comprehensive questionnaire on coping with domestic violence against women in Iranian society. This study was carried out on a random sample of women exposed to domestic violence and referred to the health and care center of Shahid Beheshti University of Medical Sciences in Tehran, and Forensic Medical Centers in Urmia city (Iran), in 2017. Two hundred questionnaires were distributed among the participants. One hundred sixty-eight questionnaires were returned to the researchers for data analysis. Eight of those were excluded from the analysis because of incompleteness. Finally, exploratory factor analysis was performed. After reviewing the literature, a questionnaire with 32 items was developed. Content validity ratio (0.95) and content validity index (0.97) were obtained. The results of exploratory factor analysis indicated that the questionnaire explained 69.34% of the data variance. Cronbach's alpha coefficient, and test-retest methods were used for determining the reliability and the obtained value, which were 0.82 and 0.81, respectively. Validity and reliability of the questionnaire with 32 items were confirmed. The tool can be utilized to measure how women cope with domestic violence.

Colorectal cancer (CRC) is the third most common malignancy in Iran. Limited data are available on knowledge and barriers in regard to CRC and screening tests in Iran. The aim of the study was to characterize knowledge, practice, and barriers toward CRC and its screening tests among an Iranian at-risk population. This cross-sectional study was conducted with participation of 200 individuals of both genders aged 50 years or older in a teaching hospital in Tehran, Iran. Data were collected via face-to-face interviews. A questionnaire containing demographics; knowledge about CRC and screening tests; screening practice; and reasons for not being screened was administered. The reliability alpha for knowledge items was 0.52. The age of the participants ranged from 50 to 83 years (mean 60.13). Overall, 11% of the respondents reported prior screening by either fecal occult blood test (6.5%) or colonoscopy (4.5%). The majority of individuals had poor knowledge although respondents with prior screening obtained slightly higher score in comparison with nonparticipants in screening (26.74 vs. 23.24; P<0.05). Four commonly cited reasons for not having CRC tests were "doctor did not recommend the test," "did not think it was needed," "never think of the test," and "no symptoms/problems" which were reported by 29%, 26%, 20%, and 17% of the participants, respectively. It is necessary to design appropriate educational interventions to increase the general population's knowledge about CRC and screening before implementing preventive programs in Iran.

In 2010, H5N8 highly pathogenic avian influenza (HPAI) viruses of the A/Goose/Guangdong/1/1996 lineage dramatically affected poultry and wild birds in Asia, Europe, and North America. In November 2016, HPAI H5N8 was detected in a commercial layer farm in Tehran province. The diagnosis was based on real-time reverse transcriptase PCR (RRT-PCR) and sequencing of haemaglutinin (HA) and neuraminidase (NA) genes from suspected samples. Genetic and phylogenetic analysis of the HA gene demonstrated that the Iranian HPAI H5N8 viruses belong to the HPAI H5 virus clade 2.3.4.4 and cluster within group B (Gochang-like). In particular, the highest similarity was found with the sequences of the HPAI H5N8 identified in Russia in 2016. To our knowledge, this clade has not been previously detected in Iran. Previous HPAI A (H5) epidemic in Iran occurred in 2015 and involved exclusively viruses of clade 2.3.2.1c. These findings indicate that Iran is at high risk of introduction of HPAI H5 of the A/Goose/Guangdong/1/1996 lineage from East Asia and highlight the need to maintain adequate monitoring activities in target wild and domestic bird species for HPAI early detection. This study is useful for better understanding the genetic and antigenic evolution of H5 HPAI viruses in the region and the world.

As social health is a condition-driven, dynamic and fluid concept, it seems necessary to construct and obtain a national and relevant concept of it for every society. Providing an empirical back up for Iran's concept of social health was the aim of the present study. This study is an ecologic study in which available data for 30 provinces of Iran in 2007 were analyzed. In order to prove construct validity and obtain a social health index, an exploratory factor analysis was conducted on six indicators of population growth, willful murder, poverty, unemployment, insurance coverage and literacy. Following the factor analysis, two factors of Diathesis (made up of high population growth, poverty, low insurance coverage and illiteracy) and Problem (made up of unemployment and willful murder) were extracted. The diathesis and problem explained 48.6 and 19.6% of social health variance respectively. From provinces, Sistan & Baluchistan had the highest rate of poverty and violence and the lowest rate of literacy and insurance coverage. In terms of social health index, Tehran, Semnan, Isfahan, Bushehr and Mazandaran had the highest ranks while Sistan and Baluchistan, Lurestan, Kohkiloyeh and Kermanshah occupied the lowest ones. There are some differences and similarities between Iranian concept of social health and that of other societies. However, a matter that makes our concept special and different is its attention to population. The increase in literacy rate and insurance coverage along with reduction of poverty, violence and unemployment rates can be the main intervention strategies to improve social health status in Iran.

Few studies regarding the health effects of long-term exposure to particulate matter with an aerodynamic diameter of 2.5 μm or less (PM 2.5 ) have been carried out in Asia or the Middle East. The objective of our study was to assess total, lung cancer and chronic obstructive pulmonary disease (COPD) mortality attributed to long-term exposure to PM 2.5 among adults aged over 30 years in Tehran from March 2013 to March 2016 using AirQ + software. AirQ + modeling software was used to estimate the number of deaths attributed to PM 2.5 concentrations higher than 10 μg m -3 . Air quality data were obtained from the Department of Environment (DOE) and Tehran Air Quality Control Company (TAQCC). Only valid stations with data completeness of 75% in all 3 years were selected for entry into the model. The 3-year average of the 24-h concentrations was 39.17 μg m -3 . The results showed that the annual average concentration of PM 2.5 in 2015-2016 was reduced by 13% compared to that in 2013-2014. The annual average number of all natural, COPD, and lung cancer deaths attributable to long-term exposure to PM 2.5 in adults aged more than 30 years was 5073, 158, and 142 cases, respectively. The results of all three health endpoints indicate that the mortality attributable to PM 2.5 decreased yearly from 2013 to 2016 and that the reduced mortality was related to a corresponding reduction in the PM 2.5 concentration. Considering these first positive results, the steps that have been currently taken for reducing air pollution in Tehran should be continued to further improve the already positive effects of these measures on reducing health outcomes.

Writing Prozāk Diaries in Tehran: Generational Anomie and Psychiatric Subjectivities.

I explore the historical and cultural shifts that underlie the normalization of the term dépréshen and the emergence of public psychiatric discourses in 1990s Iran. I do this by investigating the cultural sensibilities of a particular generation, the self-identified 1980s generation, and the ways they situate what is perceived as dépréshen in social anomie and the memories of the Iran-Iraq war. I argue that psychiatrization of psychological distress in Iran was not simply a de-politicizing hegemonic biomedical discourse, but that the contemporary Iranian discourses of psychological pathology and social loss evolved in public, hand-in-hand, through the medicalization of post-war loss. Psychiatric subjectivity describes conditions where individuals internalize psychiatry as a mode of thinking, and performatively articulate not only their desires, hopes, and anxieties, but also historical losses as embodied in individual and collective brains. I underscore my interlocutors' simultaneous historicization and medicalization of their dépréshen, arguing that psychiatrically medicalized individuals are performative actors in the discursive formation of both biomedical and social truth. Dépréshen, in the larger sense of the word, has become one way to navigate ruptured pasts, slippery presents, and uncertain futures.

The need for improved wound care is receiving considerable attention in the Islamic Republic of Iran. Beginning in 2003, maggot therapy (MT) became part of Iran's effort to advance its wound care technology. The first cohort of patients treated with MT was analysed to evaluate the use of this treatment. Patients treated with MT at three hospitals in Tehran were analysed retrospectively. Primary outcomes were time to wound debridement and time to wound healing. Factors potentially influencing primary outcomes were also recorded, including demographic factors (such as age, race, gender), wound characteristics, underlying medical illnesses, and treatment attitudes. We analysed 28 patients with 29 wounds. Most (55%) of the wounds were ischaemic, neuropathic or mixed-pathology foot ulcers in patients with diabetes. Half were considered unsalvageable. All were completely debrided and subsequently healed with MT, without amputation, grafts, or advanced interventions. Osteomyelitis was present in all cases before MT, but appeared to have been eradicated, without recurrence during at least three years' follow-up. The most common adverse events were malodour, with wound pain reported in two patients. All patients and therapists were pleased with their overall experience. Maggot therapy can provide advanced wound care even in resource-limited areas. Maggot therapy was very acceptable to the patients and their therapists.

Background: To develop nursing education and promote nursing strategies, there is a need for a staff with positive attitude. The present study was conducted to compare the attitudes among clinical nurses and nursing students toward the nursing profession. Materials and Methods: In this descriptive- analytical study 313 clinical nurses and 81 nursing students (total n = 394) of Tehran, Iran, were selected through a systematic sampling method and their viewpoints were investigated using a nursing professional attitude questionnaire. Results: The findings of this study showed that 72.6% of nurses and 65.4% of students had positive attitude toward their profession, and despite the high percentage of the clinical nurses’ positive outlook, the difference was not statistically significant (P > 0.05). Conclusion: The results showed that approximately one-third of the students and nursing practitioners had neutral or negative attitude toward their occupation. Due to the serious effect of one’s professional attitude and commitment of service, it is necessary to have further studies about the current situation to eliminate such negative factors.

Drug-food interactions can increase or decrease drug effects, resulting in therapeutic failure or toxicity. Activities that reduce these interactions play an important role for clinical pharmacists. This study was planned and performed in order to determine the role of clinical pharmacist in the prevention of absorption drug-food interactions through educating the nurses in a teaching hospital affiliated to Shahid Beheshti University of Medical Sciences, Tehran, Iran. The rate of interactions was determined using direct observation methods before and after the nurse training courses in four wards including gastrointestinal-liver, endocrine, vascular surgery and nephrology. Training courses consisted of the nurse attendance lecture delivered by a clinical pharmacist which included receiving information pamphlets. Total incorrect drug administration fell down from 44.6% to 31.5%. The analysis showed that the rate of absorption drug-food interactions significantly decreased after the nurse training courses (p < 0.001). Clinical pharmacist can play an important role in nurse training as an effective method to reduce drug-food interactions in hospitals. PMID:24363698

Objectives. We evaluated the World Health Organization’s rapid assessment and response (RAR) method of assessing injection drug use and its associated health problems, focusing on knowledge gain, capacity building, and whether RAR leads to the development of interventions reducing the health effects of injection drug use. Methods. Data were derived from RAR studies conducted in Beijing, China; Bogotá, Colombia; Greater Rosario, Argentina; Hanoi, Vietnam; Kharkiv, Ukraine; Minsk, Belarus; Nairobi, Kenya; Penang, Malaysia; St. Petersburg, Russia; and Tehran, Iran. Results. Substantial gains in knowledge and response capacity were reported at all of the study sites. Before RAR initiation, prevention and intervention programs had been absent or inadequate at most of the sites. The RARs resulted in many new or modified interventions; 7 sites reported 24 health-related interventions that were subsequently developed and influenced by the RARs. Conclusions. RARs, which require relatively little external funding, appear to be effective in linking assessment to development of appropriate interventions. The present results add to the evidence that rapid assessment is an important public health tool. PMID:16380578

Public education is one of the most important elements of earthquake preparedness. The present study identifies methods and appropriate strategies for public awareness and education on preparedness for earthquakes based on people's opinions in the city of Tehran. This was a cross-sectional study and a door-to-door survey of residents from 22 municipal districts in Tehran, the capital city of Iran. It involved a total of 1 211 individuals aged 15 and above. People were asked about different methods of public information and education, as well as the type of information needed for earthquake preparedness. "Enforcing the building contractors' compliance with the construction codes and regulations" was ranked as the first priority by 33.4% of the respondents. Over 70% of the participants (71.7%) regarded TV as the most appropriate means of media communication to prepare people for an earthquake. This was followed by "radio" which was selected by 51.6% of respondents. Slightly over 95% of the respondents believed that there would soon be an earthquake in the country, and 80% reported that they obtained this information from "the general public". Seventy percent of the study population felt that news of an earthquake should be communicated through the media. However, over fifty (58%) of the participants believed that governmental officials and agencies are best qualified to disseminate information about the risk of an imminent earthquake. Just over half (50.8%) of the respondents argued that the authorities do not usually provide enough information to people about earthquakes and the probability of their occurrence. Besides seismologists, respondents thought astronauts (32%), fortunetellers (32.3%), religious figures (34%), meteorologists (23%), and paleontologists (2%) can correctly predict the occurrence of an earthquake. Furthermore, 88.6% listed aid centers, mosques, newspapers and TV as the most important sources of information during the aftermath of an earthquake, Discussion: A participatory approach to earthquake-preparedness planning is recommended. This would ensure that program planners use methods, tools, media, and educational materials that are compatible with the culture, needs, and skills of the local communities. The findings of this study also reveal methods and tools that the local community considers to be most effective for earthquake-preparedness planning and management. The development of an earthquake-resistance and a safe community requires a high level of collaboration between broadcasting organizations, seismologists, experts in the disaster- preparedness field, as well as the local community. This will allow for timely planning, development, and dissemination of essential information to all stakeholders including the local communities. ‎

Background: Multiple sclerosis (MS) is a chronic disease prevalent in young and middle-aged people. Patients with MS often have numerous complicated needs and, consequently, require a broad range of health services. Results of a number of studies indicate that patients’ needs are only partially met. Aims: This study was conducted to explore the challenges of healthcare delivery to patients with MS in Iran. Materials and Methods: In this qualitative case study, 43 participants selected through purposeful sampling were interviewed using semi-structured method in the cities of Isfahan and Tehran in 2012–2013. Besides the interview, documentations relevant to healthcare delivery were collected from different sources, including websites of all Iranian universities of medical sciences, insurance organizations, patients’ weblogs, news agencies, the MS Center forum for MS patients, and MS Payam bimonthly. The data were analyzed through the constant comparative analysis. Results: The data were categorized into four main categories, including functional challenges (diagnosis problems, failure to pay attention to patient needs, failure to follow-up, and miscommunication), administrative challenges (resource allocation and supervision), policy-making challenges (lack of comprehensive services, bureaucracy, and problems in provision of medications), and structural challenges (difficult access to services, lack of comprehensive centers, space limit, and long wait). Conclusion: Despite all attempts of governmental and nongovernmental organizations for healthcare delivery to MS patients, these services cannot satisfy all needs of the patients. In this regard, service providers and administrators should pay more attention to the needs and expectations of patients and their families. PMID:27462625

Precipitation plays an important role in determining the climate of a region. Precise estimation of precipitation is required to manage and plan water resources, as well as other related applications such as hydrology, climatology, meteorology and agriculture. Time series of hydrologic variables such as precipitation are composed of deterministic and stochastic parts. Despite this fact, the stochastic part of the precipitation data is not usually considered in modeling of precipitation process. As an innovation, the present study introduces three new hybrid models by integrating soft computing methods including multivariate adaptive regression splines (MARS), Bayesian networks (BN) and gene expression programming (GEP) with a time series model, namely generalized autoregressive conditional heteroscedasticity (GARCH) for modeling of the monthly precipitation. For this purpose, the deterministic (obtained by soft computing methods) and stochastic (obtained by GARCH time series model) parts are combined with each other. To carry out this research, monthly precipitation data of Babolsar, Bandar Anzali, Gorgan, Ramsar, Tehran and Urmia stations with different climates in Iran were used during the period of 1965-2014. Root mean square error (RMSE), relative root mean square error (RRMSE), mean absolute error (MAE) and determination coefficient (R2) were employed to evaluate the performance of conventional/single MARS, BN and GEP, as well as the proposed MARS-GARCH, BN-GARCH and GEP-GARCH hybrid models. It was found that the proposed novel models are more precise than single MARS, BN and GEP models. Overall, MARS-GARCH and BN-GARCH models yielded better accuracy than GEP-GARCH. The results of the present study confirmed the suitability of proposed methodology for precise modeling of precipitation.

Fireworks are the leading cause of injuries such as burns and amputations during the Persian Wednesday Eve Festival (Chaharshanbeh Soori). This study was designed to explore the age of the high-risk population, the type of fireworks most frequently causing injury, the pattern of injury, and the frequency of permanent disabilities. This cohort study was performed by Tehran Emergency Medical Services at different medical centers all around Tehran, Iran, in individuals referred due to firework-related injuries during 1 month surrounding the festival in the year 2007. The following information was extracted from the patients' medical records: demographic data, the type of fireworks causing injury, the pattern and severity of the injury, the pre-hospital and hospital care provided for the patient, and the patient's condition at the time of discharge. In addition, information on the severity of the remaining disability was recorded 8 months after the injury. There were 197 patients enrolled in the study with a mean age of 20.94 ± 11.31 years; the majority of them were male. Fuse-detonated noisemakers and homemade grenades were the most frequent causes of injury. Hand injury was reported in 39.8% of the cases. Amputation and long-term disability were found in 6 and 12 cases, respectively. None of the patients died during the study period. The fireworks used during a Chaharshanbe Soori ceremony were responsible for a considerable number of injuries to different parts of the body, and some of them led to permanent disabilities.

Road accidents can be caused by different factors such as human factors. Quality of the decision-making process of drivers could have a considerable impact on preventing disasters. The main objective of this study is the analysis of factors affecting road accidents by considering the severity of accidents and decision-making styles of drivers. To this end, a novel framework is proposed based on data envelopment analysis (DEA) and statistical methods (SMs) to assess the factors affecting road accidents. In this study, for the first time, dominant decision-making styles of drivers with respect to severity of injuries are identified. To show the applicability of the proposed framework, this research employs actual data of more than 500 samples in Tehran, Iran. The empirical results indicate that the flexible decision style is the dominant style for both minor and severe levels of accident injuries. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objectives This study aimed to evaluate cardiovascular complications among patients who abuse amphetamines. Methods This cross-sectional study took place between April 2014 and April 2015 among 3,870 patients referred to the Toxicology Emergency Department of Baharlou Hospital, Tehran University of Medical Sciences, Tehran, Iran. Those with clinical signs of drug abuse and positive urine screening tests were included in the study, while cases of chronic abuse were excluded. Cardiac complications were evaluated via electrocardiography (ECG) and transthoracic echocardiography. Results A total of 230 patients (5.9%) had a history of acute amphetamine abuse and positive urine tests. Of these, 32 patients (13.9%) were <20 years old and 196 (85.2%) were male. In total, 119 (51.7%) used amphetamine and methamphetamine compounds while 111 (48.3%) used amphetamines with morphine or benzodiazepines. The most common ECG finding was sinus tachycardia (43.0%), followed by sinus tachycardia plus a prolonged QT interval (34.3%). Mean creatine kinase-MB and troponin I levels were 35.9 ± 4.3 U/mL and 0.6 ± 0.2 ng/mL, respectively. A total of 60 patients (26.1%) were admitted to the Intensive Care Unit. The majority (83.3%) of these patients had normal echocardiography results. The mean aortic root diameter (ARD) was 27.2 ± 2.8 mm. Abnormalities related to the ARD were found in 10 patients (16.7%), three of whom subsequently died. Conclusion According to these findings, cardiac complications were common among Iranian patients who abuse amphetamines, although the majority of patients had normal echocardiography and ECG findings.

Oral cancer is a global health problem; however, many dentists lack the necessary skills, knowledge and capacity to diagnose oral cancers early. This study aimed to examine the validity and reliability of a Persian short-form version of a standardised questionnaire to assess dentists' knowledge, practice and attitudes towards oral cancer. This cross-sectional analytical study was carried out in May 2015 in Tehran, Iran. An original 39-item English-language questionnaire developed by Yellowitz et al . was translated into Persian using forward and backward translation methods. A total of 15 dental professionals were asked to assess the questionnaire for content validity. Based on their feedback, a 20-item short-form version was prepared, including six demographic, six knowledge, four attitude and four practice items. The translated short-form questionnaire was subsequently distributed to 973 general dental practitioners attending a dental conference in Tehran. Internal consistency and reliability were assessed with Cronbach's alpha coefficient and item-total correlation calculations. A total of 13 professionals and 313 general dentists participated in the study (response rates: 86.7% and 32.2%, respectively). After the elimination of six items (two knowledge, two attitude and two practice items), the validity and reliability of the questionnaire was confirmed. The final Persian 14-item version of the questionnaire had acceptable validity and internal consistency. These results indicate that researchers can use this translated short-form version to evaluate oral cancer knowledge, attitudes and practices among Persian-speaking dentists; this will allow for a comparison of data between different populations.

Pica is an eating disorder characterized by the persistent ingestion of substances that the consumer does not define as food. The exact cause of pica is often unknown. The purpose of this study was to determine the prevalence of pica during pregnancy and its related risk factors. This cross-sectional study was carried out in health care centers in west of Tehran. Three hundred women were selected by stratified sampling method from the population. Demographic information and characteristics of pica during pregnancy, such as the kind, the onset, duration, frequency and the reasons, and also iron supplementation status before and during pregnancy and kind of infant feeding were collected via interview and questionnaire. The data were analyzed by chi square test and logistic regression in SPSS 16. The prevalence of pica among the studied population was 8.33%, and pagophagia (ice and freezer frost) was the most common form of pica which is characterized by the ingestion of non-food substance (76%). Sixty-four percent of women reported practicing pica regularly on a daily basis. In this study, there was significant association between pica practice and education, unwanted pregnancy, pregnancy complications, the levels of economic satisfaction, iron supplementation during pregnancy, kind of infant feeding, and type of delivery. However, there was no significant association between pica and age, employment, pregnancy ranks, the history of abortions or stillbirths, infant sex, and iron supplementation before pregnancy. Iron supplementation during pregnancy should be more considered. Also women with low education should be asked concerning pregnancy pica.

Background: Many organisations have realised the importance of human resource for their competitive advantage. Empowering employees is therefore essential for organisational effectiveness. This study aimed to investigate the relationship between employee participation with outcome variables such as organisational commitment, job satisfaction, perception of justice in an organisation and readiness to accept job responsibilities. It further examined the impact of power distance on the relationship between participation and four outcome variables. Methods: This was a cross sectional study with a descriptive research design conducted among employees and managers of hospitals affiliated with Tehran University of Medical Sciences, Tehran, Iran. A questionnaire as a main procedure to gather data was developed, distributed and collected. Descriptive statistics, Pearson correlation coefficient and moderated multiple regression were used to analyse the study data. Results: Findings of the study showed that the level of power distance perceived by employees had a significant relationship with employee participation, organisational commitment, job satisfaction, perception of justice and readiness to accept job responsibilities. There was also a significant relationship between employee participation and four outcome variables. The moderated multiple regression results supported the hypothesis that power distance had a significant effect on the relationship between employee participation and four outcome variables. Conclusion: Organisations in which employee empowerment is practiced through diverse means such as participating them in decision making related to their field of work, appear to have more committed and satisfied employees with positive perception toward justice in the organisational interactions and readiness to accept job responsibilities.

Background: Apolipoprotein A2 (APOA2) is the second major apolipoprotein of the high-density lipoprotein cholesterol (HDL-C). The study aim was to identify APOA2 gene variation in individuals within two extreme tails of HDL-C levels and its relationship with HDL-C level. Methods: This cross-sectional survey was conducted on participants from Tehran Glucose and Lipid Study (TLGS) at Research Institute for Endocrine Sciences, Tehran, Iran from April 2012 to February 2013. In total, 79 individuals with extreme low HDL-C levels (≤5th percentile for age and gender) and 63 individuals with extreme high HDL-C levels (≥95th percentile for age and gender) were selected. Variants were identified using DNA amplification and direct sequencing. Results: Screen of all exons and the core promoter region of APOA2 gene identified nine single nucleotide substitutions and one microsatellite; five of which were known and four were new variants. Of these nine variants, two were common tag single nucleotide polymorphisms (SNPs) and seven were rare SNPs. Both exonic substitutions were missense mutations and caused an amino acid change. There was a significant association between the new missense mutation (variant Chr.1:16119226, Ala98Pro) and HDL-C level. Conclusion: None of two common tag SNPs of rs6413453 and rs5082 contributes to the HDL-C trait in Iranian population, but a new missense mutation in APOA2 in our population has a significant association with HDL-C.

Abstract Background The aim of this study was to investigate the prevalence of hepatitis B, hepatitis C, HIV and syphilis infections in blood donors referred to Tehran Blood Transfusion Center (TBTC), and determine any association between blood groups and blood- borne infections between the years of 2005 and 2011. Methods This was a retrospective study conducted at TBTC. All of the donor serum samples were screened for HBV, HCV, HIV and syphilis by using third generation ELISA kits and RPR test. Initial reactive samples were tested in duplicate. Confirmatory tests were performed on all repeatedly reactive donations. Blood group was determined by forward and reverse blood grouping. The results were subjected to chi square analysis for determination of statistical difference between the values among different categories according to SPSS program. Results Overall, 2031451 donor serum samples were collected in 2005-2011. Totally, 10451 were positive test for HBV, HCV, HIV and syphilis. The overall seroprevalence of HBV, HCV, HIV, and syphilis was 0.39%, 0.11%, 0.005%, and 0.010%, respectively. Hepatitis B and HIV infections were significantly associated with blood group of donors (P <0.05) ; percentage of HIV Ag/Ab was higher in donors who had blood group “A” and percentage of HBs Ag was lower in donors who had blood group O. There was no significant association between Hepatitis C and syphilis infections with ABO and Rh blood groups (P>0.05). Conclusion Compared with neighboring countries and the international standards, prevalence of blood-borne infections is relatively low. PMID:25909065

Nowadays, restriction on access and optimum use of resources is the main challenge of development in all organizations. Therefore, the aim of this study was to determine the technical efficiency and its factors, influencing hospitals of Tehran. This research was a descriptive-analytical and retrospective study conducted in 2014-2015. Fifty two hospitals with public, private, and social security ownership type were selected for this study. The required data was collected by a researcher-made check list in 3 sections of background data, inputs and outputs. The data was analyzed by DEAP 1.0.2, and STATA-13 technique. Seventeen (31/48) of hospitals had the efficiency score of 1 as the highest technical efficiency. The highest average score of efficiency was related to social security hospitals as 84.32, and then the public and private hospitals with the average of 84.29 and 79.64 respectively. Tobit regression results showed that the size, type of practice, and ownership of hospitals were effective on the degree of their technical efficiency. However, there was no significant correlation between teaching / non-teaching hospitals with technical efficiency. Establishment of competition system among hospitals, constitution of medium size hospitals and allocation of budget to hospitals based on national accreditation system are recommended.

To the best of our knowledge, no information is available to link major dietary patterns to stunting during childhood, although dietary patterns are associated with chronic diseases. This study was conducted to determine the relationship between major dietary patterns and stunting in the first grade pupils of Tehran in 2009. In this case-control study, 86 stunted children (defined as height-for-age of less than the 5th percentile of CDC2000 cutoff points) were enrolled from among 3,147 first grade pupils of Tehran, selected using a multistage cluster random-sampling method. Participants for the control group (n=308) were selected randomly from non-stunted children (height-for-age more than the 5th percentile of CDC2000 cutoff points), after matching for age, sex, and area of residence. Dietary data were collected using two 24-hour dietary recalls through face-to-face interview with mothers. Factor analysis was used for identifying major dietary patterns. Mean consumption of dairy products (308 +/- 167 vs 382 +/- 232 g/day, p < 0.05), dried fruits and nuts (2.5819 vs 7.15 +/- 26 g/day, p < 0.05) were significantly lower among stunted children than those in the control group. Three major dietary patterns were identified: 'traditional dietary pattern' that was dominated by bread, potato, fats, eggs, flavours, vegetables other than leafy ones, sugar, drinks, and fast food; 'mixed dietary pattern' that was dominated by leafy vegetables, fast foods, nuts, fats, cereals other than bread, fruits, legumes, visceral meats, sugars, eggs, and vegetables other than leafy vegetables; and 'carbohydrate-protein pattern' that was dominated by sweets and desserts, poultry, dairy, fruits, legumes, and visceral meats. No significant relationships were found between traditional and mixed dietary patterns and stunting. Individuals in the third quartile of carbohydrate-protein dietary pattern were less likely to be stunted compared to those in the bottom quartile (OR: 0.31, 95% CI 0.13-0.78, p < 0.05). Adherence to dietary patterns high in protein (e.g. dairy, legumes, and meat products) and carbohydrates (e.g. fruits, sweets, and desserts) might be associated with reduced odds of being stunted among children.

Background and aims A surveillance system helps to detect epidemics and the pattern of the problems incidence in the community and it is essential part of evidence based decision making process. This study aimed to adapt of PRAMS and provide a model on it. Methods This study was performed in 7 steps as follows: Surveillance systems in pregnancy were reviewed and appropriate system was selected for Iran by nominal group technique. Two comparative studies were conducted to determine the similarities and differences between Iran and the selected community. PRAMS method and system were adapted based on the results of the comparative studies and experts opinions. The study tool was adapted. A field trial was conducted to assess adapted PRAMS feasibility based on TELOS (technical, economic, legal, operational, and schedule) model in the city of Shahriar, located in the west of Tehran, and to compare data collection methods. Then, based on the results and consultation with related executive managers, the final model of PRAMS was suggested for Iranian health system. Results Review of the surveillance systems in pregnancy, identified six models. The results of the nominal group technique showed that, the appropriate model for Iran is PRAMS. Based on the comparative studies and expert opinions, the appropriate system and method for program was as follows: the sampling frame was composed of data in thyroid screening forms and hospital records, the sampling method was systematic, data collection methods were home and phone based surveys, and participants were women within 2 to 6 months postpartum who had a live or still birth. The study tool was adapted. Thirty-seven health volunteers collected the data in this study (technical feasibility). Any home based completed questionnaire cost 2.45 and a phone cost 1.89 USD. Many indices were achieved from the study, which were worth much more than the expenses (economic feasibility). The project was consistent with legal requirements (legal feasibility). There was no statistically significant differences in mother's participation rate between phone (90.9%) and home visit (92.8%) groups and about 90.8% of different sections of the questionnaire were completed (operational feasibility). All data collection processes took 35 days (schedule feasibility). Based on the study results, the appropriate model of surveillance system was suggested with the goals of reducing infant morbidity and mortality and promoting maternal health by influencing maternal and child health programs, and maternal behaviors during pregnancy and early infancy. Conclusion The adapted PRAMS could be considered feasible in Iran and may offer a potential solution to some data deficits in maternal and child health indicators. Moreover, by monitoring pregnancy risks and outcomes, we can assess, analyses, and modify the current prenatal care program through PRAMS widespread and periodic implementation.

Bioremediation is a promising technique for reclamation of oil polluted soils. In this study, six methods for enhancing bioremediation were tested on oil contaminated soils from three refinery areas in Iran (Isfahan, Arak, and Tehran). The methods included bacterial enrichment, planting, and addition of nitrogen and phosphorous, molasses, hydrogen peroxide, and a surfactant (Tween 80). Total petroleum hydrocarbon (TPH) concentrations and CHEMometric analysis of Selected Ion Chromatograms (SIC) termed CHEMSIC method of petroleum biomarkers including terpanes, regular, diaromatic and triaromatic steranes were used for determining the level and type of hydrocarbon contamination. The same methods were used to study oil weathering of 2 to 6 ring polycyclic aromatic compounds (PACs). Results demonstrated that bacterial enrichment and addition of nutrients were most efficient with 50% to 62% removal of TPH. Furthermore, the CHEMSIC results demonstrated that the bacterial enrichment was more efficient in degradation of n-alkanes and low molecular weight PACs as well as alkylated PACs (e.g. C₃-C₄ naphthalenes, C₂ phenanthrenes and C₂-C₃ dibenzothiophenes), while nutrient addition led to a larger relative removal of isoprenoids (e.g. norpristane, pristane and phytane). It is concluded that the CHEMSIC method is a valuable tool for assessing bioremediation efficiency. Copyright © 2013 Elsevier B.V. All rights reserved.

Background: Effective time management is considered important for managers for achieving the goals in an organization. Head nurses can improve their efficiency and performance with effective use of time. There has always been a lot of disagreement in understanding time management behaviors of head nurses; therefore, the present study was conducted with an aim to compare the understanding of head nurses and staff nurses of the time management behaviors of head nurses employed in Social Security Hospitals in Tehran, Iran in 2011. Materials and Methods: This was a comparative descriptive study in which 85 head nurses were selected through census and 170 staff nurses were also selected through simple random sampling method from hospitals covered by the Social Security. Data collection was done through a standard inventory with high validity and reliability, which consisted of two parts: Socio-demographic characteristics and time management inventory. The obtained data were analyzed by descriptive and inferential statistics through SPSS software version 13. Results: Mean score of time management in head nurses’ viewpoint was 143.22 (±18.66) and in staff nurses’ viewpoint was 136.04 (±21.45). There was a significant correlation between the mean scores of head nurses’ time management and some of their socio-demographic characteristics such as gender, clinical experience, passing a time management course, and book reading (P < 0.05). There was a significant correlation between the mean scores of staff nurses’ time management and their clinical working experience, education, using time management approach, and type of hospital (P < 0.05). The majority of head nurses (52.9%) believed that their time management was in a high level; besides, most of the staff nurses also (40%) believed that time management of their head nurses was high. However, there was a significant difference between the perceptions of both groups on using Mann–Whitney test (P < 0.05). Conclusion: With regard to the importance of time management and its vital role in the quality of nursing care for clients, and also the fact that head nurses believed more in their time management behaviors, they are expected to improve organization's goals and developments in order to modify the weaknesses and shortages and promote the skills and capabilities of their staffs and also resolve the disagreement on the understanding of time management. Moreover, effective time management training programs can be an important step for staff nurses and their head nurses. PMID:24834090

This study was aimed to determine prevalence of vitamin D deficiency and rickets in children with cholestatic liver diseases. Forty eight children with established cholestatic liver disease who referred to gastrointestinal clinic of Children Medical Center (Tehran, Iran) between April 2010 and March 2011 were enrolled in a cross-sectional study. Laboratory analysis including calcium, phosphate, albumin, total and direct bilirubin, aminotransferases, alkalinephosphatase (ALP), prothrombin time (PT), parathyroid hormone (PTH), total protein determined by routine laboratory techniques. Mean age of participants was 299.1 ± 676.8 days (range 2-3600 days) whereas twenty one were female (43.8%) and 27 (56.3%) were male. Twenty two (45.8%) had evidences of rickets in X-ray evaluation. Three children with rickets and two with normal X-ray had vitamin D deficiency while ten in rickets group and 16 in normal group had vitamin D insufficiency. The main underlying diseases were anatomical biliary atresia in cases with rickets and idiopathic in other group. Rickets and vitamin D deficiency should be considered in chronic cholestatic children.

1995-11-01

A descriptive study was carried out in Tehran, the capital of Iran, to investigate a health education campaign on population control. A sample of 68 adults aged 20 to 40 years participated in the study. Each respondent was shown a picture of the campaign. They then filled in a short questionnaire. The main objectives of the study were to measure recall rates and to assess attitude of the subjects. The study results show that recall rates were high (78%), 68% of respondents claimed that the campaign is likely to change their attitudes towards population control, and 87% of participants perceived the main idea of the campaign correctly. The study findings show that there are some significant associations between demographic variables (marital status, having child or not) and perception of the campaign. These may lead health educators and health promoters to communicate more effectively and efficiently in the context of family planning. In countries with a large number of young people, health education campaigns on population control with respect to social values of each society and moral considerations are recommended.

Given the stressful nature of military life, people in the armed forces are vulnerable to substance use. The aim of this study was to explore the relationship between family and peers with drug use among military forces in Iran. Convenience sampling was used to recruit a total of 422 draftees doing military service in army units in Tehran, Iran. Measures of family and peers' risk and protective factors, alcohol use, and other drug use were administered. Findings indicated significant relationships between family (i.e., family models for risk behavior, parent sanctions, and family controls) and peers (i.e., peer modeling for risk behavior, peer controls, support from friends) with drug use. A multiple regression analysis revealed that peer modeling for risk behavior, family models for risk behavior, and parent sanctions were significant predictors of drug use in soldiers. These results were consistent with the influence of family and peer on drug use amongst soldiers. Programs designed to reduce alcohol and other drug use may benefit from tailoring to fit risk and protective files amongst peer and family networks.

In Iran, inpatient group psychotherapy has been limited to transient practices for research purposes or fulfilling personal interest of therapists. The goal of this paper is to share and explain the experience of developing an inpatient group psychotherapy program in Roozbeh Psychiatric Hospital, Tehran, Iran. After theoretical delineation and preparation of a draft of the program guideline, two pilot sessions were held. Based on this initial experience a final treatment guideline was prepared. Afterwards, the program was continued for more than 1 year in a female ward at Roozbeh Psychiatric Hospital. The output of this exercise was a guideline that covers important topics in development of inpatient group psychotherapy. It is concluded that inpatient group psychotherapy has its unique challenges. Of the most important challenges that can be mentioned in this regard are the participation of patients with significant differences in levels of psychopathology and psychiatric signs and symptoms, and high comorbidity with specific personality traits or disorders. Other challenges relevant to the structure of the group include items such as very limited time for working through and inevitable out-of-group contacts. PMID:26576176

Various aspects of land use regression (LUR) models for volatile organic compounds (VOCs) were systematically reviewed. Sixteen studies were identified published between 2002 and 2017. Of these, six were conducted in Canada, five in the USA, two in Spain, and one each in Germany, Italy, and Iran. They were developed for 14 different individual VOCs or groupings: benzene; toluene; ethylbenzene; m-xylene; p-xylene; (m/p)-xylene; o-xylene; total BTEX; 1,3-butadiene; formaldehyde; n-hexane; total hydro carbons; styrene; and acrolein. The models were based on measurements ranging from 22 sites in El Paso (USA) to 179 sites in Tehran (Iran). Only four studies in Rome (Italy), Sabadell (Spain), Tehran, and Windsor (Canada) met the Cocheo's criterion of having at least one passive sampler per 3.4 km2 of study area. The range of R2 values across all models was from 0.26 for 1,3-butadiene in Dallas (USA) to 0.93 for benzene in El Paso. The average R2 values among two or more studies of the same VOCs were as follows: benzene (0.70); toluene (0.60); ethylbenzene (0.66); (m/p)-xylene (0.65); o-xylene (0.61); total BTEX (0.66); 1,3-butadiene (0.46); and formaldehyde (0.56). The common spatial predictors of studied VOC concentrations were dominated by traffic-related variables, but they also included proximity to ports in the USA, number of chimneys in Canada, altitude in Spain, northern latitudes in Italy, and proximity to sewage treatment plants and to gas filling stores in Iran. For the traffic-related variables, the review suggests that large buffers, up to 5,000 m, should be considered in large cities. Although most studies reported logical directions of association for predictors, some reported inconsistent results. Some studies included log-transformed predictors while others divided one variable by another. Only six studies provided the p-values of predictors. Future work may incorporate chemistry-transport models, satellite observations, meteorological variables, particularly temperature, consider specific sources of aromatic vs aliphatic compounds, or may develop hybrid models. Currently, only one national model has been developed for Canada, and there are no global LUR models for VOCs. Overall, studies from outside North America and Europe are critically needed to describe the wide range of exposures experienced by different populations.

Background: Hymenolepis diminuta is a cestod of rodents and rarely infects humans. Infection in humans is via ingestion of infected insects. This study was aimed to detect H. diminuta cysticercoids in red flour beetles, Tribolium castaneum, and cockroaches originated from different regions of Iran. Methods: The red flour beetles and cockroaches were collected from local bakeries in five cities including Tehran, Ahvaz, Kazerun, and Sabzevar during 2010–2011. Some beetles and cockroaches were colonized in insectary and adults from F1 generation were fed on H. diminuta eggs. Both laboratory-infected and field-collected samples were dissected and examined for cysticercoids. Detection of H. diminuta DNA in T. castaneum beetles was performed by targeting a partial sequence of Ribosomal gene. Results: Except the beetles from Ahvaz, all specimens were negative for cysticercoid by microscopy. Of the four dissected beetles from Ahvaz, one harbored 12 cysticercoids. Also, 110 (52%) of laboratory-infected beetles showed infection with an average of 12–14 larvae. None of the cockroaches was infected. Two beetles from Ahvaz, including the remainder of the microscopic positive specimen, yielded the expected amplicon in PCR assay. The H. diminuta DNA sequences generated in this study were identical and matched 97–100% with similar sequences from GenBank database. Conclusion: Lack of infection in the majority of beetles may reflect a low rat infestation rate in those areas, alternatively, the examined specimens might not have been the representative samples of the T. castaneum populations.

Abstract: Background: Given the significant health effects of domestic violence against women, the present study was conducted in 2016, in Tehran, Iran in order to compare the socioeconomic status, perceived social support and mental status in women of reproductive age experiencing and not experiencing domestic violence. Methods: This descriptive-analytical cross-sectional study was conducted on 500 women. The data collection tools used included questionnaires: demographic information, Socioeconomic, Beck’s Depression, Spielberger’s Anxiety, Cohen’s Perceived Stress, Sarason’s Perceived Social Support and WHO’s Domestic Violence Inventory. Results: The results showed that 43.2% of women said they had experienced at least one case of domestic violence, among which 16.4%, 15% and 36.6% of women had experienced physical, sexual and emotional-verbal types of violence, respectively. The mean age (p less than 0.001) and educational level (p=0/018) of violated women and their spouses (p less than 0.001) were lower than those of non-violated women. Furthermore, violated women experienced lower socioeconomic status (p less than 0.05), higher perceived stress (p less than 0.008), higher depression (p less than 0.001), and higher overt anxiety (0.002. They also perceived lower levels of social support (p less than 0.001). Conclusions: The issue of domestic violence was rather prevalent in the participants of the present study, particularly the younger, less educated and more socioeconomically deprived communities and families.

Multiple sclerosis (MS) is a chronic disease prevalent in young and middle-aged people. Patients with MS often have numerous complicated needs and, consequently, require a broad range of health services. Results of a number of studies indicate that patients' needs are only partially met. This study was conducted to explore the challenges of healthcare delivery to patients with MS in Iran. In this qualitative case study, 43 participants selected through purposeful sampling were interviewed using semi-structured method in the cities of Isfahan and Tehran in 2012-2013. Besides the interview, documentations relevant to healthcare delivery were collected from different sources, including websites of all Iranian universities of medical sciences, insurance organizations, patients' weblogs, news agencies, the MS Center forum for MS patients, and MS Payam bimonthly. The data were analyzed through the constant comparative analysis. The data were categorized into four main categories, including functional challenges (diagnosis problems, failure to pay attention to patient needs, failure to follow-up, and miscommunication), administrative challenges (resource allocation and supervision), policy-making challenges (lack of comprehensive services, bureaucracy, and problems in provision of medications), and structural challenges (difficult access to services, lack of comprehensive centers, space limit, and long wait). Despite all attempts of governmental and nongovernmental organizations for healthcare delivery to MS patients, these services cannot satisfy all needs of the patients. In this regard, service providers and administrators should pay more attention to the needs and expectations of patients and their families.

This study identifies challenges to the first nurse training program for undergraduate nursing students at a nursing and midwifery school in Iran using a collaborative approach in order to improve the program. Action research was used as a research strategy with qualitative content analysis and quantitative evaluation. The participants were 148 individuals from nursing academic and clinical settings, including administrators, faculty members, students, and staff nurses. We obtained approval from the research deputy and ethics committee of Shahid Beheshti University of Medical Sciences in Tehran, Iran for this study. Lack of coherence in the educational program and implementation of the program, inadequate communication between management inside and outside the organization, insufficient understanding of situations by students, and improper control of inhibitors and use of facilitators in teaching and in practice were among the major challenges in the first training process in the context of this study. After classification of problems, the educational decision-making authorities of the school developed an operational program with stakeholder cooperation to plan initial reforms, implementation of reforms, reflection about the actions, and evaluation. Comparison of student satisfaction with the collaborative learning process versus the traditional method showed that except for the atmosphere in the clinical learning environment (p>.05), the mean differences for all dimensions were statistically significant. The results confirm the overall success of the revised partnership program, but stressed the need for further modification of some details for its implementation in future rounds. Copyright © 2016.

In the absence of dysphagia-oriented food products, rheological characterization of available food items is of importance for safe swallowing and adequate nutrient intake of dysphagic patients. In this way, introducing alternative items (with similar ease of swallow) is helpful to improve quality of life and nutritional intake of esophageal cancer dysphagia patients. The present study aimed at rheological characterization and cluster classification of potentially suitable foodstuffs marketed in Iran for their possible use in dysphagia diets. In this descriptive study, rheological data were obtained during January and February 2012 in Rheology Lab of National Nutrition and Food Technology Research Institute Tehran, Iran. Steady state and oscillatory shear parameters of 39 commercial samples were obtained using a Physica MCR 301 rheometer (Anton-Paar, GmbH, Graz, Austria). Matlab Fuzzy Logic Toolbox (R2012 a) was utilized for cluster classification of the samples. Using an extended list of rheological parameters and fuzzy logic methods, 39 commercial samples (drinks, main courses and desserts) were divided to 5 clusters and degree of membership to each cluster was stated by a number between 0 and 0.99. Considering apparent viscosity of foodstuffs as a single criterion for classification of dysphagia-oriented food products is shortcoming of current guidelines in dysphagia diets. Authors proposed to some revisions in classification of dysphagia-oriented food products and including more rheological parameters (especially, viscoelastic parameters) in the classification.

To evaluate the changes in pulmonary volumes during and after Islamic fasting. It is a cohort study conducted on 117 healthy subjects selected on a random basis from employees, professors and students of Iran University of Medical Sciences, Tehran, Iran, between December 1999 and January 2000. All of them underwent spirometry 10 days prior to Ramadan, 2 times during Ramadan, and one time 10 days post-Ramadan. In first visit, in addition to spirometry they underwent medical examination to make sure they are healthy. All of their spirometries and background information were collected. Repeated measurements analysis of variance method was used to compare the measurements. Approximately 69% of subjects were male and the mean age was 23.9 years. Mean fasting time was 27.8 days. The mean difference in forced expiratory volume in 1 second (FEV1%) was significant between the 4 visits (p=0.01). The mean FEV1% increased both during fasting and after Ramadan (p=0.017). The mean vital capacity and peak expiratory flow rate values increased during Ramadan significantly (p=0.043, p<0.001). Although the mean maximum mid-expiratory flow decreased in the beginning of Ramadan and significantly increased subsequently (p=0.02), MEF50% (p=0.004) and MEF75% (p=0.047) increased in the beginning of Ramadan and decreased subsequently. As a whole, fasting increases lung volumes and might improve pulmonary function. This finding seems to be relevant to the changes in weight during Ramadan.

The first step in any seismic hazard study is the definition of seismogenic sources and the estimation of magnitude-frequency relationships for each source. There is as yet no standard methodology for source modeling and many researchers have worked on this topic. This study is an effort to define linear and area seismic sources for Northern Iran. The linear or fault sources are developed based on tectonic features and characteristic earthquakes while the area sources are developed based on spatial distribution of small to moderate earthquakes. Time-dependent recurrence relationships are developed for fault sources using renewal approach while time-independent frequency-magnitude relationships are proposed for area sources based on Poisson process. GIS functionalities are used in this study to introduce and incorporate spatial-temporal and geostatistical indices in delineating area seismic sources. The proposed methodology is used to model seismic sources for an area of about 500 by 400 square kilometers around Tehran. Previous researches and reports are studied to compile an earthquake/fault catalog that is as complete as possible. All events are transformed to uniform magnitude scale; duplicate events and dependent shocks are removed. Completeness and time distribution of the compiled catalog is taken into account. The proposed area and linear seismic sources in conjunction with defined recurrence relationships can be used to develop time-dependent probabilistic seismic hazard analysis of Northern Iran.

The characteristics of cutaneous melanoma in the Middle-Eastern countries is poorly described. Therefore we conducted this study to determine the characteristics of melanoma in Iran. A retrospective, cross sectional study of melanoma patients seen at a tertiary referral centre, Iran, from May 2004 to October 2014. Clinical data included age and gender of the patients at the time of diagnosis, tumour location and tumour size. Histological characteristics included Breslow thickness, Clark level and subtype of tumour. A total of 450 cases of melanoma with a male/female ratio of 1.1:1 were reviewed. The mean age of patients was 57.5 years. The most frequent histological subtypes were acral lentiginous melanoma (30%) and lentigo maligna melanoma (29%). In 215 cases (49%) the tumour was located on the extremities. The second most common site was the face. Tumour invasion was mainly at Clark level III and IV. The mean Breslow thickness was 2.8 mm; 143 (38%) melanomas had a Breslow thickness less than 1 mm (T1) and 86 (23%) were more than 4 mm (T4). This study indicates that clinical and histological features of melanoma in Iranians (who are mainly of skin phototypes 3-4) are different from those observed in Western countries. Further cohort studies are required to evaluate the role of ethnic and environmental risk factors for melanoma in different populations. © 2017 The Australasian College of Dermatologists.

Frequent air pollution episodes have been reported for Tehran, Iran, mainly because of critically high levels of fine particulate matter (PM2.5). The composition and sources of these particles are poorly known, so this study aims to identify the major components and heavy metals in PM2.5 along with their seasonal trends and associated sources. 24-hour PM2.5 samples were collected at a main residential station every 6 days for a full year from February 2014 to February 2015. The samples were analyzed for ions, organic carbon (including water-soluble and insoluble portions), elemental carbon (EC), and all detectable elements. The dominant mass components, which were determined by means of chemical mass closure, were organic matter (35%), dust (25%), non-sea salt sulfate (11%), EC (9%), ammonium (5%), and nitrate (2%). Organic matter and EC together comprised 44% of fine PM on average (increased to >70% in the colder season), which reflects the significance of anthropogenic urban sources (i.e. vehicles). The contributions of different components varied considerably throughout the year, particularly the dust component that varied from 7% in the cold season to 56% in the hot and dry season. Principal component analyses were applied, resulting in 5 major source factors that explained 85% of the variance in fine PM. Factor 1, representing soil dust, explained 53%; Factor 2 denotes heavy metals mainly found in industrial sources and accounted for 18%; and rest of factors, mainly representing combustion sources, explained 14% of the variation. The levels of major heavy metals were further evaluated, and their trends showed considerable increases during cold seasons. The results of this study provide useful insight to fine PM in Tehran, which could help in identifying their health effects and sources, and also adopting effective control strategies.

Health inequality monitoring especially in Health care financing field is very important. Hence, this study tends to assess the inequality in household's capacity to pay and out-of-pocket health carepaymentsin Tehran metropolis. This cross-sectional study was performed in 2013.Thestudy population was selected by stratified cluster sampling, and they constitute the typical households living in Tehran (2200 households). The required data were collected through questionnaires and analyzed using Excel and Stata v.11. Concentration Index on inequality was used for measuring inequality status in capacity to pay and household payments for health care expenses; and also the concentration index for out-of-pocket payments and capacity to pay was used to determine the extent of inequality. The recall period for inpatient care was one year and 1 month for outpatient. The average of out-of-pocket payments for receiving the outpatient services was determined to be 44.33US$ and for each inpatient1861.11 US$. Concentration index for household's outof- pocket payments for inpatient health care, out-of-pocket payments for outpatient health care and health prepayments were calculated 0.13, -0.10 and -0.11, respectively. Also, concentration index in household's capacity to pay was estimated to be 0.11whichindicatedinequality to the benefit of the rich. The households used financing strategies like savings, borrowing or lending to pay their health care expenditures. According to this study, the poor spend a greater portion of their capacity to pay for outpatient and inpatient health care costs and prepayment, in comparison to the rich. Thus, supporting the vulnerable groups of the society to decrease out-of-pocket payments and increasing the household's capacity to pay through government support in order to improve the household economic potential, must be considered very important.

Identifying the underlying factors contributing to smoking among teenagers is important in establishing smoking control programs. The present study was designed to identify and compare factors revealed in a preceding qualitative study conducted on 13-15 year-old boys living in two different socio-economic districts in the Northern and Southern parts of Tehran. Two completely similar case-control studies, each with 200 subjects, were conducted using a snowball sampling. The case and control subjects were matched based on the intimacy relations, i.e. six smokers were recruited in each of the Northern and Southern districts; they were then asked to introduce one of their smoker friends as a case and a non-smoker one as a control. Multi-variable conditional logistic regression revealed that having a smoker father is the single effective factor in the two districts. As for boys living in the Northern (wealthier) part of the city, social capital (OR: 0.59, 95% CI: 0.43-0.81) played a protective role against smoking, whereas quitting home after a quarrel (OR: 15.07, 95% CI: 1.54-147.25), monthly allowance (OR: 2.22, 95% CI: 1.29-3.82) and hyperactivity (OR: 1.69, 95% CI: 2.64-240.45) were associated with a higher risk of becoming a smoker. The studied variables can be classified as personal, familial, and school-level factors. Familial intervention is effective for all the factors which revealed to be influential on the risk of becoming a smoker. It could be concluded that interventions on the family level should be used to prevent the cigarette use in Tehran.
