Aims Venomous snake bites are public health problems in different parts of the world. The most specific mainstay in the treatment of envenomation is anti-venom. To treat the envenomation, it is very important to identify the offending species. This study was designed to determine the penetrating pattern of fangs and teeth of some viper snakes. Materials & Methods This descriptive study was performed on live venomous and nonvenomous snakes from 2010 till 2011. All 47 sample snakes were collected from different regions of Isfahan province such as Kashan City, Ghamsar, Niasar, Mashhad Ardehal, Taher-Abad and Khozagh. Their mouths were inspected every two weeks and development of their fangs and teeth were recorded by taking clear digital photos. Fangs and teeth patterns of samples were drawn and the results were compared. Findings One or two wounds appeared as typical fang marks at the bite site of venomous snakes while non-venomous snakes had two carved rows of small teeth. Three different teeth and fang patterns were recognized in venomous snakes which were completely different. Conclusion The fang marks of venomous snakes do not always have a common and classic pattern and there are at least 3 different patterns in Isfahan province, Iran. [ABSTRACT FROM AUTHOR]

Introduction: The goal of the current study was evaluation of the pain related psychological similarities in patients suffering from musculoskeletal chronic pains and their spouses who had visited the orthopedic clinic in Atieh Hospital. Method: Based on the inclusion/exclusion criteria such as the ability to read and write and the ability to work with both hands, 59 couples visiting the clinic were selected and were asked to answer VAS, Tampa Scale of Kinesio phobia, pain catastrophizing questionnaire and DASS- 42. Also they were asked to do the Pictorial Dot-Probe task. Results: The results showed no significant differences in TSK, rumination scale, magnification scale, and VAS scores in patients with chronic pain and their spouses. Conclusion: It seems that musculoskeletal chronic pains affect both patients' and their spouses' beliefs, cognition, and behaviors. Such influences can interfere with different dimensions of care givers' life such as their physical, psychological, and social conditions. It is expected that similar psychological characteristics among couples result in continuation of current situation of patients and their spouses. It is possible that couples aggravate each other's behaviors, which will result in the continuation of such behaviors. [ABSTRACT FROM AUTHOR]

Absconding by psychiatric patients from acute psychiatric wards has been a significant problem for some time. This study was conducted to identify the incidence rate of absconding in a psychiatric hospital and some of the characteristics of patients who had escaped from hospital in year 2006. In this descriptive cross-sectional study, all of absconds in our centre have been registered in the period of 9 months. We assessed patients' age, gender, marital status, hospital stay, substance abuse, psychiatric diagnosis and site of absconding. A total of 43 cases of absconding have been registered in this period, attempted by 35 patients, with the incidence rate of 3% in our centre. The mean age of absconders was 31.7 years; 95.3% of absconds were made by men; 67.4% were single; 37.4% absconded through the main door; 62.8% of our absconders had bipolar mood disorder or schizophrenia; mean in hospital stay before absconding was 18.4 days; and 53.5% of absconds were attempted by substance users. Absconders utilize a significant portion of hospital resources and have an adverse effect on ward milieu. It seems that the patients who are more prone to abscond are male, young, single, addict, with the diagnosis of bipolar mood disorder or schizophrenia and patients who are admitted not long ago.

Introduction:Approximately 50 to 80 million people in the world suffer from infertility. Laparoscopy is golden standard for diagnosing tubal and peritoneal pelvic diseases, making all pelvic organs visible. Applications of laparoscopy include investigations and treatment of infertility, diagnosis and treatment of endometriosis, lysis of adhesions, depletion of ovarian cysts, and polycystic ovaries cautery which nearly consist 80% of laparoscopic infertility treatment cases. Materials and Methods: This cross-sectional study was performed on 162 women who had not responded to alternative treatments and were undertaking laparoscopic treatments in Peymanieh Hospital of Jahrom City. Information including patients‘ age, occupation, frequency of marriage, type of infertility, sperm quality and partner pregnancy rates following surgery was collected. Results: Patients‘ age ranged between 16-43 years old. 93.8% of patients consisted of housekeepers. 95.7% had their first marriage and 80.2 % of patients had primary infertility. Husbands‘ spermogram results showed 91.5 % were normal; only 12 patients (7.5 %) had abnormal results. Pregnancy rate was 56.9 % after laparoscopic surgery, and most pregnancies followed polycystic ovarian cauterization. All pregnancies occurred spontaneously. 83.15 % cases of pregnancies were delivered and 16.85 % terminated in abortion. None of the patients had complication or ectopic pregnancy following laparoscopic. Conclusion:Out of 162 patients studied 89 pregnancies occurred, most of which followed removal of an ovarian cyst and polycystic ovarian electrocautery (84%). Results showed that laparoscopic ovarian cauterizationis an effective technique in treating infertility. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Open globe injuries (OGI) represent a main preventable reason for blindness and visual impairment, particularly in developing countries. The goal of this study is evaluating key variables affecting the prognosis of open globe injuries and validating internally and comparing different machine learning models to estimate final visual acuity., Materials and Methods: We reviewed three hundred patients with open globe injuries receiving treatment at Khatam-Al-Anbia Hospital in Iran from 2020 to 2022. Age, sex, type of trauma, initial VA grade, relative afferent pupillary defect (RAPD), zone of trauma, traumatic cataract, traumatic optic neuropathy (TON), intraocular foreign body (IOFB), retinal detachment (RD), endophthalmitis, and ocular trauma score (OTS) grade were the input features. We calculated univariate and multivariate regression models to assess the association of different features with visual acuity (VA) outcomes. We predicted visual acuity using ten supervised machine learning algorithms including multinomial logistic regression (MLR), support vector machines (SVM), K-nearest neighbors (KNN), naïve bayes (NB), decision tree (DT), random forest (RF), bagging (BG), adaptive boosting (ADA), artificial neural networks (ANN), and extreme gradient boosting (XGB). Accuracy, positive predictive value (PPV), recall, F-score, brier score (BS), Matthew correlation coefficient (MCC), receiver operating characteristic (AUC-ROC), and calibration plot were used to assess how well machine learning algorithms performed in predicting the final VA., Results: The artificial neural network (ANN) model had the best accuracy to predict the final VA. The sensitivity, F1 score, PPV, accuracy, and MCC of the ANN model were 0.81, 0.85, 0.89, 0.93, and 0.81, respectively. In addition, the estimated AUC-ROC and AUR-PRC of the ANN model for OGI patients were 0.96 and 0.91, respectively. The brier score and calibration log-loss for the ANN model was 0.201 and 0.232, respectively., Conclusion: As classic and ensemble ML models were compared, results shows that the ANN model was the best. As a result, the framework that has been presented may be regarded as a good substitute for predicting the final VA in OGI patients. Excellent predictive accuracy was shown by the open globe injury model developed in this study, which should be helpful to provide clinical advice to patients and making clinical decisions concerning the management of open globe injuries., (© 2024.

- Abstract
Anopheles stephensi is an efficient vector of malaria parasites in Iran. Despite its importance in malaria transmission, there is a scarcity of accurate predictive models of its rates of development at different temperatures. A laboratory colony of An. stephensi, collected from Bandar Abbas County, southern Iran, was established, and all its developmental stages were maintained in temperature-controlled incubators so that the water temperature set at 5, 8, 10, 12.5, 14, 28, 38, 39.5, 42, and 45(±0.2) °C for different treatments until subsequent adult emergence. The Lower and Upper Developmental Temperatures (LDT and UDT) and the growth degree-day (GDD) were calculated for each development stage. A 12-mo population dynamics survey of the larvae and adults of An. stephensi was performed in 3 malaria-endemic villages (Geno, Hormoodar, and Sarkhoon) of Bandar Abbas County, and the obtained data were matched with the constructed GDD model. Based on the field meteorological and dynamics data, the model was verified in the field and used to determine the appropriate date to start spraying. The LDT was determined to be 8.19, 9.74, 8.42, 5.6, 13.57, and 10.03 °C for egg hatching, first, second, and third ecdysis, pupation, and eclosion events, respectively. The UDT was 38 °C for all developmental stages. The thermal requirement for the development of all immature stages of An stephensi was determined to be 187.7 (±56.3) GDD above the LDT. Therefore, the appropriate date to start residual spraying is when the region's GDD reaches 187.7 (±56.3). Given the climatic conditions in Bandar Abbas County, it is expected that the first activity peak of adult An. stephensi would be in March. Field observations showed that An. stephensi activity starts in February and peaks in March. The GDD model can provide a good estimate for peak An. stephensi activity and indicate the optimal deployment time of residual spraying operations against the multiplication and development of malaria parasites inside the vector., (© The Author(s) 2023.

- Abstract
Background: In acute myocardial infarction (AMI), timely recognition of symptoms and early hospital presentation positively affect patient morbidity and mortality. Due to the high burden of ischemic heart disease in Iran, this study aimed to identify factors affecting the level of knowledge, responses at the time of AMI onset, and sources of health information among the Iranian population., Method: This cross-sectional study was conducted in three tertiary hospitals in Tehran, Iran. An expert-validated questionnaire was used to obtain data. A total of 400 individuals were enrolled., Result: Among the respondents, 285 people(71.3%) considered "chest pain or discomfort," and 251 (62.7%) regarded "pain or discomfort in the arm or shoulder" as MI symptoms. Approximately 288 (72.0%) respondents had poor knowledge of the AMI symptoms. Knowledge of symptoms was higher among those with higher levels of education, those with medical-associated jobs, and those who resided in the capital areas. Major risk factors identified by the participants were: anxiety (340)(85.0%), obesity (327)(81.8%), an unhealthy diet (325)(81.3%), and the presence of high LDL levels (258)(64.5%) and Diabetes Mellitus (164)(41.0%) were less appreciated. Calling an ambulance (286)(71.5%) was the most common treatment-seeking behavior in the case of a suspected heart attack., Conclusion: It is vital to educate the general population about AMI symptoms, particularly those with comorbidities at the greatest risk for an AMI episode., (© 2023.

- Abstract
The hypertonicity of internal anal sphincter resting pressure is one of the main causes of chronic anal fissure. Therefore, the aim of this study was to assess the effect of oral administration of L-arginine on the improvement of the anal fissures by relaxing the internal anal sphincter. Seventy-six chronic anal fissure patients (aged 18-65 years) who were referred to Rasoul-e-Akram Hospital, Tehran, Iran from February 2019 to October 2020 participated in this randomized, double-blind, placebo-controlled trial. Participants were allocated into treatment (L-arginine) and placebo groups. They took a 1000 mg capsule three times a day for 1 month, and then we followed them at the end of the first and third months after the intervention. Clinical symptoms, anal sphincter resting pressure, and quality of life (QoL) were completed at baseline and the end of the study. The analysis of data showed a significant decrease in bleeding, fissure size, and pain for each group; however, in the L-arginine group was more than the control group at the end of the study (P values < 0.001). Following that, a significant increase in QoL was seen just in patients treated with L-arginine (P value = 0.006). In addition, the comparison of anal pressures at baseline and, between groups at the end of the study showed a significant reduction in sphincter pressure in patients treated with L-arginine (P value < 0.001, = 0.049; respectively). The oral administration of 3000 mg L-arginine can heal chronic anal fissures by reducing internal anal sphincter pressure with more negligible side effects. However, we recommend long-term study with more extended follow-up.Clinical trial registry: IRCT20190712044182N1 at Iranian clinical trials, date: 2019-08-27., (© 2022.

- Abstract
Background: The risk factors for acute kidney injury (AKI) development in patients with diabetes hospitalized for COVID-19 have not been fully studied yet. In this study, we aimed to estimate the rate of AKI among the hospitalized population with COVID-19 and to identify the risk factors associated with AKI among patients with diabetes. Material and Methods. This retrospective cohort study included 254 patients (127 with diabetes and 127 without diabetes) who were admitted for COVID-19 to a tertiary hospital in Tehran, Iran, between February and May 2020. Clinical characteristics and outcomes, radiological findings, and laboratory data, including data on AKI, hematuria, and proteinuria were recorded and analyzed., Results: Of 254 patients, 142 (55.9%) were male and the mean (± SD) age was 65.7 years (±12.5). In total, 58 patients (22.8%) developed AKI during hospitalization, of whom 36 patients had diabetes ( p = 0.04); most patients (74.1%) had stage 1 or 2 AKI. Also, 8 patients (13.8%) required renal replacement therapy (RRT) after developing AKI. Regardless of diabetes status, patients who developed AKI had significantly higher mortality rates compared with patients who did not develop AKI ( p = 0.02). Hematuria and proteinuria were observed in 38.1% and 55% of patients, respectively. Multivariate analysis showed that invasive mechanical ventilation, proteinuria, HBA1c level, history of cardiovascular disease, and use of statins were independent risk factors for AKI development in patients with diabetes., Conclusion: Results of this study showed that AKI develops in a considerable percentage of patients with COVID-19, especially in those with diabetes, and is significantly associated with mortality., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Shayesteh Khalili et al.)

- Abstract
Background: There is inadequate information on the risk of gastrointestinal (GI) bleeding in patients who are under rivaroxaban and warfarin therapy in Iran. Determining the risk of GI bleeding in patients receiving these two drugs can help to select a more appropriate anti-coagulation prophylaxis in high-risk patients., Objective: The aim of this study was to compare the incidence of GI bleeding in patients with atrial fibrillation (AF) and concomitant bleeding risk factors receiving either warfarin or rivaroxaban., Methods: In this observational study, 200 patients with AF and bleeding risk factors who referred to Imam Hossein Hospital (Tehran, Iran) were included. The patients were under treatment with either warfarin or rivaroxaban. The incidence of GI bleeding was compared between the two groups monthly for one year., Results: GI bleedings were observed in 61% and 34% of patients treated with warfarin and rivaroxaban, respectively (P = 0.001).Melena was the most common type of GI bleeding in both groups. History of hypertension, history of stroke, consumption of anti-platelet drugs, NSAID consumption, and history of alcohol consumption were associated with more frequent GI bleeding only in warfarin group., Conclusion: The incidence of GI bleeding was lower in AF patients who received rivaroxaban compared to those treated with warfarin. Also, GI bleeding risk does not change according to the consumption of other anti-coagulant drugs and underlying history of hypertension or stroke in patients received rivaroxaban. Therefore, rivaroxaban is suggested as the choice of prophylaxisin patients with AF and concomitant coagulopathy., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background and Aims: Botulinum toxin type A (BTX-A) have been recently administered to improve Diabetic neuropathies; however, the efficacy of this treatment for relieving pain in painful diabetic polyneuropathy (DPN) has not been studied yet. Herein, we investigated the efficacy of botulinum toxin A (BTX-A) on DPN., Methods: This prospective, randomized, double-blind, controlled trial was performed in Imam Hossein Medical Center, pain clinic (Tehran, Iran). Diabetic patients (141 cases), between 40 and 70 years old with polyneuropathy in lower limbs were randomly assigned to one of these three groups: 1. Group D1 received 150 units of BTX-A in one foot and normal saline 0.9% in the other foot, 2. Group D2 received BTX-A 150 units in both feet, 3. Group N received normal saline 0.9% in both feet. All injections were performed intradermally using insulin syringes in 20 different points of foot. Visual analogue scale (VAS) and neuropathy pain scale (NPS) were used to compare the groups., Results: The improvement of VAS, pain intensity, sharp and hot sensation, sensitive and unpleasant sensation, deep and surface sensation was significant when comparing BTX-A and placebo groups. However, dull and cold sensations improvement (p = 0.114, and p = 0.653; respectively) did not show a significant difference between BTX-A injection and placebo groups. Furthermore, the percentage of changes after treatment indicated that sharp pain was improved more than other complaints (80%, 81%, and 37% for D1, D2, and N groups; respectively)., Conclusion: Intradermal administration of BTX-A was effective in improving VAS and all of the items of NPS in patients with diabetic polyneuropathy, except for dull and cold sensation., Competing Interests: Declaration of interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Diabetes India.

- Abstract
Aedes caspius has a wide distribution throughout the world and can transmit Chikungunya virus, West Nile Virus (WNV), Tahyna virus and the bacterium Francisella tularensis . Sequences of the mitochondrial cytochrome C-oxidase subunit 1 (COI) and cytochrome C-oxidase subunit 2 (COII) genes have been widely used to estimate phylogenetic relationships at different taxonomic levels among this species. Adult collections were carried out by human bait, Center for Deseases Control Light Traps (CDC-LT) and aspirator during February/April, June and October/December 2013-2015 from different southern provinces of Iran and then identified morphologically with reliable keys. A total of 3,570 adult mosquitoes were collected and identified as belonging to three genera, including five species of Culex, six species of Aedes and one species of Culiseta. In this study, 1,796 specimens of Aedes caspius were identified from four provinces. Based on the COI and COII sequences obtained for Ae. caspius population, 12 and 11 haplotypes were identified, respectively. The present study evidenced a high degree of intraspecific variation among these populations of Ae. caspius ., Competing Interests: The authors have no conflicts of interest to declare

- Abstract
Introduction: Adverse events are relatively common in healthcare, leading to extensive harm to patients and a significant drain on healthcare resources. Identifying the extent, nature and consequences of adverse events is an important step in preventing adverse events and their consequences which is the subject of this study., Methods: This is a retrospective review of medical records randomly selected from patients admitted to 4 general hospitals, staying more than 24 hours and discharged between April and September 2012. We randomly selected 1200 records and completed the record review for 1162 of these records. Standard forms (RF1 and RF2) were used to review medical records in two stages by nurses and medical doctors., Results: Eighty-five (7.3%) of the 1162 records had an adverse event during the admission; and in 43 (3.7%) of the 1162 records, the patient was admitted to the hospital due to an adverse event that occurred before the admission. Therefore, a total of 128 (11.0%) adverse events occurred in 126 (10.9) records as two patients had more than one adverse event. Forty-four (34.3%) of these 128 adverse events were considered preventable., Conclusions: This study confirms that adverse events, particularly adverse drug reactions, post-operative infections, bedsore and hospital acquired infections are common and potentially preventable sources of harm to patients in Iranian hospitals.

- Abstract
Purpose: The snoring, tiredness, observed apnea, blood pressure, body mass index, age, neck circumference, gender (STOP-BANG) is a concise and effective obstructive sleep apnea (OSA) screening tool, part questionnaire (STOP), and part demographic or anthropometric measurements (BANG). The main purpose of this study was to translate this well-liked questionnaire into Persian and assess its reliability and validity in sleep clinic population., Methods: Standard forward-backward method was used for translation. A sample of 603 patients, who admitted to the sleep clinic, completely answered to the STOP questionnaire and underwent in-laboratory polysomnography, included in this study. Height, weight, and neck circumference were measured by technicians for calculating BANG score. The apnea-hypopnea index (AHI) on the polysomnography was used as gold standard for OSA diagnosis: none (AHI < 5), mild (5 ≤ AHI < 15), moderate (15 ≤ AHI < 30), and severe (AHI ≥ 30). One hundred and forty one patients were answered to the STOP questionnaire twice at a time interval of 2-4 weeks for test-retest analysis., Results: In reliability analysis, 124 (87.9 %) patients had same STOP score and 130 (92.2 %) patients were classified in same risk of OSA. Based on the polysomnography, 438 patients (72.6 %) had mild (n = 124, 20.4 %), moderate (n = 114, 18.9 %), and severe (n = 201, 33.3 %) OSA, whereas according to the STOP-BANG, 502 patients (83.3 %) were at high risk of OSA. The sensitivity and specificity of the STOP-BANG were found to be 91.6 and 45.2 %, respectively, at AHI ≥ 5, 97.1 and 35.2 %, respectively, at AHI ≥ 15, and 98 and 29.4 %, respectively, at AHI ≥ 30. The area under the curve of the STOP-BANG for identifying mild, moderate, and severe OSA was 0.805, 0.779, and 0.755, respectively., Conclusions: Persian version of the STOP-BANG performs similar to its original version and is an easy-to-use questionnaire which could be considered as a reliable and valid tool for OSA screening.

- Abstract
Background: The main aim of this study was to assess the trends in hydrogenated vegetable oil (HVO) consumption and some related factors among northern Iranian families from 2006 to 2010., Methods: A cross-sectional, population-based study was conducted with 6497 subjects, 15 to 65 years old, who were chosen by multistage cluster random sampling. The subjects were randomly chosen by 325 clusters with an equal size (n = 20 subjects). A multidimensional questionnaire including sociodemographic questions and type of cooking oil used were administered by interviewers., Results: The percentages of the sample reporting HVO consumption across the 5 years are as follows: 2006, 85.2%; 2007, 79.7%; 2008, 75.9%; 2009, 59.3%; and 2010, 55.7%. Consumption decreased 29.5% during the 5 years of study and an average of 5.9% per year (P < .05). The estimated odds ratio of HVO consumption in rural areas verus urban areas was 2.59 (95% confidence interval [CI], 2.31-2.90); for poor compared with good economic level the odds ratio was 3.99 (95% CI, 3.13-5.10 for; for the uneducated versus college-educated sample it was 5.75 (95% CI, 4.10-8.17); and the odds ratio was 3.34(95% CI, 2.51-4.45) for Sisstani compared with Fars-native ethnic group., Conclusion: HVO consumption decreased during the 5-year study (2006 to 2010), but HVO is still used extensively in northern Iran. Preventive early intervention strategies are needed to target uneducated and poor families, with an emphasis on the Sisstanish ethnic group, to increase awareness about the negative consequences of HVO consumption.

- Abstract
Objective: To assess molecular characterization, distribution, seasonal activities of sandfly species and Leishmania parasites infecting them for this zoonotic cutaneous leishmaniasis focus., Methods: The collections were carried out in 2009-2011 using CDC traps, Sticky Papers and manual aspirator in and around the villages in Abarkouh district. Individual sandflies were characterized by PCR amplification and sequencing of fragments of their mitochondrial cytochrome b gene. Leishmania parasite infections within sandflies were performed by targeting Cyt b, ITS-rDNA, k-DNA and microsatellite genes., Results: The PCR assays detected only Leishmania major (L. major). All infections (30) were found in the abundant and widespread vector Phlebotomus papatasi (P. papatasi). Small numbers of other sandfly species were also screened for infections, but none was found. Sergentomyia sintoni and P. papatasi were the predominant members in all locations of this district and in all habitats throughout the trapping season. Only five other sandfly species were found, namely Phlebotomus ansari, Phlebotomus caucasicus, Phlebotomus sergenti, Sergentomyia dentata and Sergentomyia merviney., Conclusions: In the current survey, the only infections detected are of L. major in females of P. papatasi (30 out of 190). The rates of infection of P. papatasi by L. major are not significantly different in compare with other locations in Iran with no diversity of parasite strains. Zoonotic cutaneous leishmaniasis may have emerged only recently in Abarkouh district, and the reason may well be the instability of the transmission cycles there., (Copyright © 2013 Hainan Medical College.

- Abstract
Purpose: The main purpose of this study was to assess the reliability and validity of the Iranian version of the Epworth Sleepiness Scale (ESS-IR)., Methods: This was a cross-sectional study of 507 suspicious patients either to obstructive sleep apnea (n = 466) or narcolepsy (n = 41) in order to carry out a psychometric evaluation of the ESS-IR by performing reliability, validity, and responsiveness analyses. Reliability of the ESS-IR was assessed by internal consistency and test-retest reliability. Validity of the instrument was assessed using several statistical approaches including construct validity (exploratory factor analysis), discriminant validity, and criterion validity. Responsiveness of the ESS-IR was assessed by comparing the ESS-IR total score before and after 6-9 months of continues positive airway pressure (CPAP) treatment in 16 patients with obstructive sleep apnea (OSA)., Results: The ESS-IR had an acceptable internal consistency and test-retest reliability. Factor analysis in both groups showed a two-factor solution for the ESS-IR, but the first factor showed statistically significant loads in all items. In addition, the ESS-IR discriminated well between patients with and without OSA. There is a fair correlation between the ESS-IR total score and multiple sleep latency test results that is not significant at all. Finally, the ESS-IR was found to be responsive to change where the total score was significantly decreased after CPAP treatment (P < 0.001)., Conclusion: The findings suggest that the ESS-IR is a reliable and valid measure for evaluating daytime sleepiness and now can be used in research and clinical settings in Iran.

- Abstract
Background: Clinical governance (CG) is among the different frameworks proposed to improve the quality of healthcare. Iran, like many other countries, has put healthcare quality improvement in its top health policy priorities. In November 2009, implementation of CG became a task for all hospitals across the country. However, it has been a challenge to clarify the notion of CG and the way to implement it in Iran. The purpose of this action research study is to understand how CG can be defined and implemented in a selected teaching emergency department (ED)., Methods/design: We will use Soft Systems Methodology for both designing the study and inquiring into its content. As we considered a complex problem situation regarding the quality of care in the selected ED, we initially conceptualized CG as a cyclic set of purposeful activities designed to explore the situation and find relevant changes to improve the quality of care. Then, implementation of CG will conceptually be to carry out that set of purposeful activities. The activities will be about: understanding the situation and finding out relevant issues concerning the quality of care; exploring different stakeholders' views and ideas about the situation and how it can be improved; and defining actions to improve the quality of care through structured debates and development of accommodations among stakeholders. We will flexibly use qualitative methods of data collection and analysis in the course of the study. To ensure the study rigor, we will use different strategies., Discussion: Successful implementation of CG, like other quality improvement frameworks, requires special consideration of underlying complexities. We believe that addressing the complex situation and reflections on involvement in this action research will make it possible to understand the concept of CG and its implementation in the selected setting. By describing the context and executed flexible methods of implementation, the results of this study would contribute to the development of implementation science and be employed by boards and executives governing other clinical settings to facilitate CG implementation.

- Abstract
Background & Objectives: Malaria is the most important mosquito-borne disease in Iran. It is endemic in south to southeastern part of the country. Knowledge about bio-ecology of vectors will support authorities for appropriate management of the disease. Bashagard district is one of the main endemic areas for malaria in south of Iran. This study was conducted to determine anopheline fauna, diversity and affinity in the area, characterization of larval habitats, and mapping their potential distribution across the district., Methods: The potential aquatic habitats for Anopheles larvae were extracted from Indian Remote Sensing Satellite (IRS) image and digital elevation model of the area using GIS. Surface water bodies were sampled monthly during 2009–10 for anopheline larvae, while characteristics of their physical environment were recorded and water samples were analyzed., Results: A total of 4511 Anopheles larvae were found during the year with the lowest and highest frequencies in February and April, respectively. Dominant species was Anopheles culicifacies. The Shanon diversity index ranged from 0.570–0.829 at fixed collection sites, while the affinity index was significant among some vector species., Conclusion: Riversides and riverbeds were the main breeding places which provided sandy, rocky, and clay beds for different species. The potential breeding places as well as distribution of collected species were mapped. Knowledge about ecology of malaria vectors provides information to health sector for effective control programs.

- Abstract
Bashagard district is one of the important malaria endemic areas in southern Iran. From this region a total of 16,199 indigenous cases have been reported in recent years. The aim of this study was to determine the situation of the disease and provide the risk map for the area. ArcGIS9.2 was used for mapping spatial distribution of malaria incidence. Hot spots were obtained using evidence-based weighting method for transmission risk. Environmental factors including temperature, relative humidity, altitude, slope and distance to rivers were combined by weighted multi criteria evaluation for mapping malaria hazard area at the district level. Similarly, risk map was developed by overlaying weighted hazard, land use/land cover, population density, malaria incidence, development factors and intervention methods. Our results reveal that the disease mainly occurs in north and east of the study area. Consequently the district is divided into three strata. Appropriate interventions are recommended for each stratum based on national malaria policy. Malaria hazard and risk map, stratification based on relevant information and data analyzing provide a useful method preparedness and early warning system for malaria control, although regular updating is required timely., (Copyright © 2012 Elsevier B.V.

- Abstract
Primary immunodeficiency diseases (PIDs) consist of a group of genetic disorders that predispose the patients to immune-mediated complications. The aim of this study was to assess the knowledge of Iranian general practitioners and pediatricians about PIDs.A questionnaire consisting 52 closed questions on clinical symptoms, laboratory data, associated syndromes and management of PIDs patients was made valid and reliable by a pair pilot study. Then the questionnaire was filled by pediatricians, general practitioners and pediatric residents from different regions of Iran. Totally, 333 physicians (50 general practitioners, 52 pediatric residents, 182 pediatric specialists, and 49 pediatric sub specialists) participated in this study. The mean total score was 55.9±14.3 (i.e. about 29 correct answers out of 52 questions). One hundred and five participants (31.9%) answered correctly more than two third of all questions. In order to qualitatively compare the groups a ranking system was used. Total scores was significantly different between physicians groups (p<0.01). Pediatric subspecialties gained the highest rank, which was significantly over the other participants (p<0.05). This study showed that there is a considerable lack of awareness on PIDs in physicians. This may be one of the major reasons in late diagnosis and the delay in adequate treatment deteriorating patients' morbidity and mortality. Retraining classes and reconsidered educating schedules are needed as an efficient strategies and improving physicians' knowledge about PIDs.

- Abstract
Bashagard is an important malaria endemic area in south of Iran. An epidemiological and entomological survey was performed during 2002-2010. The aim of study was to determine malaria situation, species composition of anopheline mosquitoes and susceptibility status of main vectors to insecticides/larvicides. A total of 13,490 malaria cases were recorded, Plasmodium vivax (99.64%), P. falciparum (0.35%) and mix cases (0.01%). The highest and lowest Annual Parasite Incidence (API) were observed in 2007 (145.72/1000) and 2009 (6.29/1000), respectively. Anopheles culicifacies, An. dthali, An. stephensi, An. superpictus, An. fluviatilis, An. moghulensis, An. turkhudi and An. apoci were collected from the area. Two peak activities occur in April and October. The first five species were confirmed as malaria vectors in Iran. No indication of sporozoite in mosquitoes using molecular method was performed. Susceptibility tests using diagnostic dose of insecticides and larvicides showed only resistance of An. stephensi to DDT. Tolerance in An. stephensi to deltamethrin and bendiocarb is reported. The same phenomenon was observed in An. culicifacies to DDT, propoxur and deltamethrin, and in An. dthali to malathion and deltamethrin. Larvae of vectors were susceptible to all larvicides, except for An. stephensi that exhibited tolerance to fenthion. In conclusion it should be emphasized that malaria transmission is a complex process in Bashagard. This event is attributed to five proven vectors with different behaviors which are active in the area. Regarding tolerance of vectors to deltamethrin, resistance management is suggested by using new insecticide with novel mode of action., (Copyright © 2011. Published by Elsevier B.V.)

- Abstract
Obesity and its related emotional and physical consequences are a worldwide problem. Obese individuals are usually stigmatized. This study is proposed to assess the correlation between body mass index, gender and age with psychiatric symptoms among Iranian students. A number of 9172 students aged 10-18 years (53.5% girls and 46.5% boys) from all provinces of Iran participated in this study. Data was collected using the global school based health survey questionnaire of the World Health Organization (GSHS-WHO). Overall, prevalence of predictors of having emotional problems, depression and anxiety were 27.8%, 29.7% and 11.5% respectively. Girls had significantly higher prevalence of predictors of psychiatric symptoms. Overall obesity was a protective factor against emotional problems OR (CI95%):0.79(0.65-0.98), but it was attributable to obese boys OR (CI95%):0.72(0.55-0.95). Depression and anxiety symptoms were higher in intermediate school girls and high school girls and boys. More attention should be paid to girls' psychological problems. Besides, obesity had an indirect relation with predictors of having psychiatric problems in Iranian boys and it might be due to: (1) parents' beliefs about heaviness as a predictor of healthiness, (2) boys' lower vulnerability to psychological consequences of obesity and (3) lower pressure from parents on their obese sons to lose weight.

- Abstract
Although the error in health care has received attention recently, patient safety culture in health centers has been relatively neglected. To measure the patient safety culture in primary health centers. A cross-sectional study, utilizing the modified version of the Hospital Survey on Patient Safety Culture (HSOPSC) developed by the Agency for Healthcare Research and Quality (AHRQ) and a demographic questionnaire. Healthcare staffs from health centers were participated in the survey. The patient safety culture score including subscores on 11 dimensions and 39 items; patient safety grade and number of events reported. The overall positive response rate of patient safety culture was 57 ± 16.8 (CI (95)55%-59%). The dimensions that received higher positive response rate were "Teamwork across units of health center", "Teamwork within units", "Head of center support for patient safety". The lowest percentage of positive responses was "Non punitive response to error". There were no relationship between working years and patients safely culture score. Similarly, no relationship was found between professional, gender and total patients safely culture score. Statistical analysis showed discrepancies between Iranian health centers and the US hospitals in three dimensions. For improving patient safety culture in health centers, it is necessary to have enough staff and establish an environment to be open and fair with staff which helps report errors spontaneously and without any fear. The findings of this study could be used to measure changes in patient safety culture over the time.

- Abstract
Introduction: p16(INK4A) is a tumor suppressor encoding the Cdk inhibitor protein, which acts to repress Cdk4/6 and pRb phosphorylation. p16(INK4A) gene can be inactivated by a variety of events, including promoter hypermethylation., Materials and Methods: To investigate the methylation status of the p16(INK4A) gene in Iranian patients with breast carcinoma, promoter methylation was studied by methylation-specific PCR (MSP) and restriction enzyme-related PCR (REP). In addition, p16(INK4A) promoter was analyzed by PCR-SSCP in order to detection of mutation and single nucleotide polymorphisms., Results: Analysis of 70 patients by MPS and REP showed hypermethylation of p16(INK4A) promoter in 35.7% (25/70) and 40% (28/70) of samples, respectively. Comparison of the molecular data and pathological information of the samples suggested that p16(INK4A) gene might be inactivated at the early stages in breast cancer., Conclusion: Therefore, it could be suggested that hypermethylation of p16(INK4A) promoter is one of the epigenetic factors affecting the progress of sporadic breast carcinogenesis in Iranian patients.

Because of its geographic proximity to the major drug production centres, there is easy access to narcotic drugs in the Islamic Republic of Iran despite efforts by governmental and nongovernmental organizations. Using a structured questionnaire as a basis for conversation, local health workers interviewed 310 residents of a rural area in Babol province about opium use. The self-reported rate of opium use, adjusted due to a bias in the sex ratio of the sample, was 8.9%. All the 42 opium users reported opium use at least 2-3 times per week in the previous 3 months. Opium was smoked by 95.2% and taken orally by 4.8%; there was no injecting use. There was no reported use of other substances, including alcohol. There was a statistically significant relationship between opium use and male sex, unemployment and cigarette smoking.

- Abstract
Aluminum phosphide (AlP) is a solid fumigant widely used in Iran as a grain preservative. When reacted with water or acids, AIP produces phosphine gas, a mitochondrial poison that interferes with oxidative phosphorylation and protein synthesis. Poisoning by AIP is one of the most important causes of fatal chemical toxicity in Iran. There are few studies in the medical literature addressing prognostic factors associated with AlP poisoning. In this prospective study conducted across a 14-month period commencing on 21st March 2006, we enrolled all patients admitted to the ICU of Loghman-Hakim Hospital Poison Center (Tehran, Iran) with AIP poisoning, no history of diabetes mellitus diagnosed before hospitalization, and normal body mass index. We recorded patient-specific demographic information, blood glucose level on presentation (before treatment), arterial blood gas (ABG) analysis, time elapsed between ingestion and presentation, ingested dose, duration of intensive care admission, and outcome data related to each presentation. We enrolled the group of patients who survived the intoxication as a control group and compared their blood glucose levels with those who died because of AlP poisoning. Data were analyzed by Statistical Product and Service Solutions (SPSS) software (Version 12; Chicago, Ilinois, USA) using logistic regression, Pearson correlation coefficient and Student's t-test. P values of 0.05 or less were considered as the statistical significant levels. Forty-five patients (21 women and 24 men) with acute AlP poisoning were included in the study. The mean age was 27.3 +/- 11.5 years (range: 14-62 years). Thirteen patients survived (29%) and 32 expired (71%). AlP poisoning followed deliberate ingestion in all patients. The time elapsed between ingestion and arrival at the hospital was 3.2 +/- 0.4 h. There was no significant difference between survived and non-survived groups according to age, gender, and time to treatment. However, the difference between mean blood glucose levels in survived (143.4 +/- 13.7 mg/dL) and non-survived (222.6 +/- 20 mg/dL) cases was statistically significant (P = 0.021). There was no significant correlation between blood glucose level and time to treatment, age, gender, pH, HCO3 concentration, and ingested dose. Twenty-three (71.9%) of non-survived and four (30.8%) of survived patients had a blood glucose level greater than 140 mg/dL. After adjusting according to age, gender, ingested dose, pH and HCO3 concentration The odds ratio for hyperglycemia as a risk factor for death was 5.7 (CI of 1.4-23.4). In our study, patients who succumbed to AIP poisoning had significantly higher mean blood glucose levels than those who survived. This correlation of hyperglycemic effect and mortality suggests that it may be useful in guiding risk assessment and treatment of AIP poisoning. Management of hyperglycemia may have a useful role in treatment of these patients by allowing increased entrance of glucose into cells and reducing oxygen consumption.

- Abstract
Asthma is one of the most common acute and chronic conditions in children, and the pediatricians are expected to provide an important role for asthma care in this age group, however there is no published information describing the different aspects of their practices about children asthma in Iran. This study was done to characterize the knowledge of the Iranian pediatricians about the diagnosis, treatment and education of asthma in children. Validated questionnaires were completed by 193 pediatricians from different parts of Iran during the International Congress of Pediatrics in Tehran. A total of 193 returned questionnaires (96.5%) were eligible for the survey and analysis. About 49% of the respondents were male and 18% were sub-specialists. Wheezing was the most common mentioned symptoms in taking asthma into consideration. About 40% of these physicians had no plan for doing spirometry in eligible children and 35.2% of them did not have familiarity with peak flowmeter. Also about 17.6% of them paid no regular visits to their asthmatic patients. Only 29% of the respondents indicated that they would prescribe inhaled corticosteroids for a 6-year-old child with moderate persistent asthma and 73.3% of them would prescribe inhaled bronchodilator (Salbutamol) for an acute asthmatic attack as the first drug, while 17.1% of them used epinephrine injection for this purpose. About 42.2% of the respondents did not consider any education or action plan for their patients and only 60.6% of them had access to standard guidelines and educational programs. The results show that there are numerous aspects of children asthma management in Iran which are not consistent with standardized guidelines and recommendations. This survey and the attained information suggest areas for interventions to improve the pediatricians' knowledge about asthma and the disease management.

Typhi) isolates recovered from sporadic cases of typhoid fever in Tehran, Iran during 2004. Antimicrobial susceptibility test showed that all isolates were susceptible to 20 antimicrobials examined in this study. Analysis of insertion elements showed that 2 IS200 types with 10 and 11 copies were present. 11 of the 15 isolates were found to possess 10 IS200 elements residing on fragments from 23 to 2.3 kb. Comparison of the RiboPrinter (automated ribotyping) patterns of S. Typhi showed that 60% (9/15) of the isolates belonged to a single ribotype. PCR based random amplified polymorphic DNA analysis (RAPD) and enterobacterial repetitive intergenic consensus (ERIC) and pulsed-field gel electrophresis (PFGE) were also performed. ERIC and RAPD-PCR method showed 2 and 3 genotyping patterns amongst the isolates, respectively. The PFGE typing was carried out by using XbaI restriction enzyme, and 7 restriction patterns were observed. Overall, the molecular typing methods applied in this study showed that the isolated S. Typhi populations were highly polyclonal as shown by PFGE.

- Abstract
In this study, 50 Vibrio cholerae O1 serotype Inaba isolates were collected during several cholera outbreaks throughout Iran during the summer of 2005. The results of antibiotic susceptibility testing showed that 86, 84, 84 and 82 % of the isolates were resistant to streptomycin, chloramphenicol, co-trimoxazole and tetracycline, respectively. The strains were genotyped using randomly amplified polymorphic DNA (RAPD), PFGE and ribotyping techniques. PCR showed that 100, 98 and 98 % carried the ctx, zot and ace genes, respectively. Biochemical fingerprinting of the isolates using the PhenePlate (PhP) system showed a low diversity index level (0.755), suggesting that the strains were highly homogeneous. Among the strains, 100 and 96 % showed an identical ribotype and PFGE patterns, respectively. The two isolates showing different PFGE patterns also exhibited discrete PhP types. RAPD was able to discriminate the isolates into six distinct groups, suggesting some genetic dissimilarity was present among the strains. These ribotyping, PFGE and PhP techniques revealed the clonal dissemination of a single V. cholerae strain throughout Iran in 2005.

- Abstract
Vitamin D (Vit D) is an essential element for the regulation of serum calcium, phosphate, and alkaline phosphatase (Alk Ph). Because the Vit D serum level is not usually measured directly, Vit D deficiency is diagnosed indirectly by changes in serum calcium, phosphate, and Alk Ph leves. The current study assessed the status of these biochemical parameters in subjects with different degrees of Vit D deficiency. We selected 1,210 subjects, between 20 and 69 years old, randomly from the Tehran population. Subjects with diseases or medications that modified bone metabolism were excluded from the study. Serum 25(OH) D, calcium, phosphate, Alk Ph, and parathyroid hormone (PTH) levels were measured and the status of these biochemical parameters was compared in subjects with different degrees of Vit D deficiency. Vit D deficiency was diagnosed in 79.6% of the subjects. Different degrees of Vit D deficiency were classified as follows: group 1, severe; group 2, moderate; and group 3, mild. Serum PTH levels in the Vit D-deficient groups were significantly higher than that in group 4 (normal Vit D). Serum calcium and phosphate levels in groups 1 and 2 were significantly lower than those in groups 3 and 4. No significant difference was seen in serum Alk Ph in the groups with different degrees of Vit D deficiency. The sensivity for at least one biochemical variable (calcium, phosphorus, or Alk Ph) for the detection of severe, moderate, and mild Vit D deficiency was 24.2%, 13.8%, and 6%, respectively. When the serum 25(OH) D level was reduced to less than 25 nmol/l (groups 1 and 2), the effects of Vit D deficiency on calcium and phosphate levels were obvious. Therefore, the usual biochemical parameters (calcium, phosphate, Alk Ph) alone do not have sufficient sensitivity to detect mild deficiency of Vit D.

- Abstract
Background: There are multiple studies in different countries regarding the prevalence of vitamin D deficiency. These studies showed high prevalence of vitamin D deficiency in Asian countries. This study tries to elucidate the prevalence of vitamin D deficiency and its influencing factors in population of Tehran., Methods: 1210 subjects 20-64 years old were randomly selected. 25 (OH) D serum levels were measured. Duration of exposure to sunlight, the type of clothing and level of calcium intake and BMI were quantified based on a questionnaire., Results: A high percentage of vitamin D deficiency was defined in the study population. Prevalence of severe, moderate and mild Vitamin D deficiency was 9.5%, 57.6% and 14.2% respectively. Vitamin D serum levels had no significant statistical relation with the duration of exposure to sunlight, kind of clothing and BMI. Calcium intake in the normal vitamin D group was significantly higher than the other groups (714.67 +/- 330.8 mg/day vs 503.39 +/- 303.1, 577.93 +/- 304.9,595.84 +/- 313.6). Vitamin D serum levels in young and middle aged females were significantly lower than the older group., Conclusions: Vitamin D deficiency has a high prevalence in Tehran. In order to avoid complications of vitamin D deficiency, supplemental dietary intake seems essential.

- Abstract
Mosquitoes of the Anopheles maculipennis complex were collected in nine provinces of Iran (Esfahan, Fars, Gilan, Golestan, Kohkiluyeh va Boyerahmad, Mazandaran, Tehran, Azarbaijan-e Gharbi and Zanjan) between June 1983 and September 2002. The nuclear rDNA ITS2 sequences of 86 specimens were compared with those of seven species of the complex available in GenBank. Three genetically distinct species of the complex were distinguished: A. maculipennis Meigen, A. sacharovi Favre and a previously unrecognized species. The last species is most similar to, but clearly distinct from, A. martinius Shingarev and A. sacharovi. The taxonomy of A. martinius and A. sacharovi is critically reviewed, and justification is provided for formally recognizing the third species as Anopheles persiensis sp.n. The new species is the first culicid to be characterized and named principally on the basis of DNA evidence. Anopheles persiensis was collected only in the northern Caspian Sea littoral provinces of Gilan and Mazandaran, and it seems likely that this species could be responsible for malaria transmission in this region that was previously attributed to A. maculipennis. A species-specific RFLP-PCR assay based on ITS2 sequences was developed to facilitate further studies of the three species in Iran.

- Abstract
A diagnostic polymerase chain reaction (PCR) assay using species-specific primers and direct sequencing was used to identify members of the Anopheles maculipennis complex in the north-west and central regions of the Islamic Republic of Iran. Specimens were collected from 9 provinces during 2 seasonal activities in 2001-2002, identified morphologically and subjected to PCR assay and direct sequencing. Results showed that only 2 species, An. maculipennis Meigen, and An. sacharovi Faver, were present in the area of study. This was confirmed by the high similarity (99.2%-100%) of their sequences with those available in GenBank. The molecular data and relative distribution of these species in relation to their vectorial capacity and the epidemiology of malaria in the region are discussed.
