    Background: Finding the best location for the airport reduces the negative effects of construction and its activity on the environment. This study aimed to evaluate the establishment of the airports (Mehrabad and Imam Khomeini airports) in Tehran province through integration of multi-criteria decision making (MCDM) methods and noise pollution modeling software. Methods: The criteria for zoning the airports were determined using Delphi method, and then, were weighed using analytic network process (ANP). One of the criteria was noise pollution. The computer aided noise abatement (CadnaA) software was used to map the noise level at the airports. The geographic information system (GIS) software and weighted overlay method were used to zone Tehran province for construction of the airports. The percentage of voice annoyance was defined according to the questionnaire provided by the International Commission on the Biological Effects of Noise (ICBEN). Results: Prioritization between the selected criteria using ANP and TOPSIS showed that the most important criteria are the land use (0.069) and the distance from the city (0.0598), respectively. The highest percentage of highly annoyed (%HA) persons was reported at both airports at Lden levels above 70 dB. Conclusion: According to the results of this study, the location of Mehrabad and Imam Khomeini airports is considered 60% and 18% inappropriate, respectively. The results introduce a set of criteria that determines compatibility rate of different activities around the airports based on the noise levels. Finally, it is recommended to study the correlation between aircraft noise pollution indicators in other airports of Iran and design a local model for the whole country.

    Background: The key role of leptin is regulation of appetite and body lipid and pregnancy is a condition associated with overeating, reduction in heating and adaptation of lipid cells, culminating in increased body fat mass. So, this study was conducted to examine the relationship between changes in pre-pregnancy BMI and leptin. Methods: This Longitudinal study was conducted on 45 women in the first trimester of pregnancy using a longitudinal approach and convenience sampling method in Tehran city in 2015. The mothers in terms of pre-pregnancy BMI were divided into two groups: group A (n=22 with normal BMI) and group B (n=23 with high BMI), with maternal serum leptin being taken in 6-12 weeks and 15-20 weeks of pregnancy and measured by enzyme-linked immunosorbent assay (ELISA). The statistical data were analyzed by SPSS V.21 using Kolmogorov Smirnov, independent t-test, two-sample Chi square, Mann-Whitney, Regression, Pearson and Landa tests with P.V<0.05. Results: The mean age of mothers in the present study was 27.47±5.55 years with a minimum age of 19 and a maximum age of 37 years. The mean plasma leptin of the first and second trimesters of pregnancy was significantly higher in the high BMI group than in the normal group. The correlation showed that the first trimester leptin and changes in leptin levels of pregnancy with pre-pregnancy BMI were significantly higher in the normal group (P=0.04 and P=0.003). Conclusions: BMI before and during pregnancy can be a predictor of maternal serum leptin in pregnancy weight gain. &nbsp

    Background and Aim: Data mining in medical sciences provides countless opportunities for demonstrating hidden patterns of a data set. These patterns can help general physicians and health workers in preventing diseases. This study aimed to forecast delay times in post-exposure prophylaxis (PEP) to human animal bite injuries in central Iran using a decision tree analysis. Materials and Methods: The data of 2072 human animal bite cases were collected from Centers for Disease Control and Prevention unit of Qom Provincial Health Center, Iran from January 2017 to December 2018. The information related to animal bite incidents, including the biting animal characteristics and data on the bitten humans, was obtained by investigating the epidemiological survey forms of human animal bites. The decision tree model was applied to forecast the delay time of receiving PEP. Results: A delay of more than 48 h in the initiation of PEP was estimated among 12.73% of animal bite victims. The most important variables to predict delay time of receiving PEP were the species of biting animal, time and cause of animal bite occurrences in 24 h a day, respectively. Hence, the model showed a delay in the initiation of PEP if the biting animal was a cattle or, a carnivore, and the time of being bitten was from 7 am to 1 pm, or if the animal was carnivore and the time of being bitten was between 1 and 7 pm, and the cause of animal bite was playing with the animal. Conclusion: Based on the findings of the study on different variables affecting the initiation of PEP, the concepts related to animal bite and rabies, including the timely injection of anti-rabies vaccine to prevent rabies, it is a must to educate and train, all the people, especially housewives and students

    Background and Objectives: Schema is a cognitive and emotional pattern, which can affect individual behaviors. This study was performed to investigate mental health problems and personality characteristics in female students in Qom city. Methods: This cross-sectional study was carried out on 151 female students of Qom high schools in three disciplines of Mathematical Sciences, Humanities, and Experimental Sciences in 2011-2012 academic years. Sampling was performed in two steps; first cluster sampling and then stratified sampling with proportional allocation to each cluster. Participants answered a 75-question questionnaire, &ldquo;Young Early Maladaptive Schemas&rdquo;. Data were analyzed using Kruskal&ndash;Wallis, spearman correlation coefficient, and Lambda statistics. Results: The mean age of the students was 15&plusmn;1.5 years. Unrelenting standards schemas (in domain of over vigilance/inhibition), failure and dependency (in dimension of impaired autonomy), and defectiveness and shame (in dimension of disconnection and rejection) had the highest mean scores, respectively. None of the mean scores had a significant difference according to three academic groups. But the correlation between the schemas was statistically significant in the academic groups (p<0.05). Conclusion: In this study, 2 out of the 4 schemas with the highest mean belonged to impaired performance domain. Given that this schema is formed by parental behavior during childhood, therefore, one of the strategies can be training of parents to improve children&rsquo;s confidence and not over caring of them. &nbsp

    &nbsp;&nbsp;Introduction: Spasms or seizures during the first month of life are the most common clinical manifestations of central nervous system failure in infants and occur due to overactivity of a group of nerve cells in the brain and excessive electrical stimulation of neurons. The purpose of the present study was to evaluate the prevalence of renal complications of Levetiracetam in neonates with seizures. Methods: This descriptive-analytical and retrospective study was performed on creatinine level, blood urea and duration of levetiracetam use for all neonates studied and only renal ultrasound was performed for cases where their creatinine was elevated. Finally, the obtained information was used for statistical analysis. Results: According to the results, there was no statistically significant differences in neonatal subgroups,&nbsp;&nbsp; especially in infants on levetiracetam, except transient increased creatinine and urea. During 6 months follow-up, only three cases with increased creatinine above 1.4 was observed. This 3 cases had normal genitourinary ultrasound. &nbsp;Also, in neonates diagnosed with choroid cyst on ultrasound, in one case the creatinine level was more than 1.4 and in the other cases the serum creatinine level was less than 1.4. Conclusion: According to the results of the present study, no serious renal complication was observed with Levetiracetam and its use can be recommended for patients
