Abstract
Background & objectives: Urinary Tract Infection (UTI) which unfortunately has no clear symptoms in many cases is the second prevalent infection among children after respiratory infection. This study carried out in order to determine the frequency of asymptomatic UTI among elementary school girls in one of Tehran’s suburbs
(Mahalat town).
Methods: In a cross sectional study, all elementary school girls (n=1216) of study town who were between 6 to 11 years of age, were screened with urinary strip dipstick test method and urinary culture test was carried out on persons who had urinary PH> 7 and positive nitrite, as cases were doubtful to UTI. Afterwards, positive culture cases were referred to a urology specialist for investigating symptoms and, asymptomatic UTI samples were recognized.
Results: Among 67 students who were doubtful to UTI (based on dipstick strip test), 14 cases out of (%1.15 from 1216 samples), that is %1.15, were suffering from UTI. Regarding symptoms of UTI, just %35.72 of infected persons possessed at least one symptom of UTI and most of them that is %64.28, possessed asymptomatic UTI and the percentage of these people were obtained %0.74 for whole screened statistical society.
Conclusions: Since asymptomatic UTI and its probable complications might be recurrent, screening in dipstick method which is effective, rapid and inexpensive is completely necessary to improve the level of public health especially for children.

Abstract
Background & Objectives: Peavalu on sage sümptom, mis võib olla tõsine problem iga inimese igas vanuserühmas. Several studies have shown that the prevalence of migraine and tension-type headache (TTH) varied between different geographical regions. Since there is little known about this in the country the current research has been conducted with the aim of estimating the prevalence of these types of migraines, reporting and comparing their clinical characteristics in this region of Iran.
Methods: This study conducted on 1150 admitted patients by first diagnosis of headache in Farabi hospital in Kermanshah during a period of one year from 2010 till 2011. Case definition was based on International Classification of Headache Disorders (ICHD) criteria. Among these, 350 patients were diagnosedd as headache patients and completed the International Headache Schedule form. Data were analyzed by the use of descriptive frequency and percentage SPSS 16 software.
Results: The results indicate that women were stricken more than men by headache (P<0.0001). Migraine was more prevalent in the age groups of 30-41 that included 54 individual (15.4%). the tension headache was more common among the age group of 42-53 that constitute 58 people (%23.3) of the participants. A significant correlation was also reported between the position and type of the headache (P<0.0001). Findings of this research showed that 20.4% of people with migraine and nearly 9 percent (9%) of persons with tension headaches have lost their job because of their headaches. There is meaningful relation between tension headaches and experience into their second job struggling (P<0.026).
Conclusion: It is concluded that migraine and tension headaches seem two separate diseases and none of them has any effect on the other. Headache requires more attention and it should be, diagnosed and managed appropriately.

Abstract
Background & Objectives: Breast cancer is the most common cancer among women. Numerous factors are effective in the improvement of patients undergoing surgery in terms of preventing relapse or need for repeated treatment during 6 months after the surgery. This study aimed to determine the factors affecting improvement of patients undergoing surgery for breast cancer using a logistic regression model.
Methods: In this study information of 150 patients were extracted from the surgical records of patients underwent surgery at the Cancer Institute of Tehran Imam Khomeini Hospital. Data were analyzed through SPSS software and using logistic regression models .
Results: Of 150 studied patients, 18 patients (12%) were not fully recovered while 132 (88%) had complete remission. The mean age of the patients was 43 ± 7.5 years, 92.8% were married, and 87.3% had children. According to the results, the odds of non recovery increased by 1.26 times with each one-year increase in age, 5.3 times with each one lymph node involvement, and 8.67 times in the case of metastasis. Other variables, such as marital status, number of children, tumor size, and location of the metastasis showed no significant relationship.
Conclusion : The Results showed that age at diagnosis, due to its relationship with metastases and number of involved lymph nodes can be directly or indirectly affect the outcome. Therefore, increasing the women's awareness about breast cancer seems to be necessary for early diagnosis which requires planning a sufficient screening program by health policy makers of the country.

Abstract
Background and Objectives: Shift work as a pervasive phenomenon in various industrial sectors is one of the most stressful factors in the workplace. Considering the contradictory reports on the relationship of shift work and hypertension, the main objective of the present study was to investigate the relationship between these two variables among petrochemical industry staff of Mahshahr, Iran.
Methods: In this longitudinal study, 3254 petrochemical staff were investigated during 2008-2011. According to work schedule, shift workers were divided into two groups of shift work and day work (1872 day workers and 1382 shift workers). The aim of this research was to assess the effect of shift work on hypertension by adjusting confounding variables such as gender, age, body mass index, and smoking. The data were analyzed using a random-effects logistic regression model.
Results: Of 3254 (3142 males and 112 females) subjects, 37.85% (860 subject) were hypertensive. The random effects model, with controlling covariates, showed no significant relationship between shift work and hypertension (OR=1.04, 95% CI= (0.98, 1.10). Moreover, the variance of the random effects was significant.
Conclusion: Generally, according to the results of this study, shift work is not a significant risk factor for hypertension.

Abstract
Background and Objectives: Shift work could threaten health in the long term. The present research aimed to assess the association between shift work and body mass index (BMI) using the multilevel (hierarchical) model during a particular period of time.
Methods: The data of this longitudinal study were collected from a sample of Esfahan’s Mobarakeh steel and Polyacryl companies personnel during 2008 to 2011. Shift work schedule included day work and rotational shift work. The multilevel regression model was utilized for analysing the data and assessing the effect of shift work on BMI by controlling confounding variables including marital status, work expectation, age, company, and educational level.
Results: In this study, of 1368 workers, 42.3% (n=578) and 57.7% (n=790) were day workers and rotating shift workers, respectively. The mean (±SD) age of the day workers and rotating shift workers was 33.07 (±8.66) years and 33.31 (±8.70) years, respectively. After adjusting for confounding variables in a two-level hierarchical model, the association between shift work and BMI was not statistically significant (P=0.837). About 90% of total variation was related to personnel.
Conclusion: According to the results of the present study, no statistically significant relationship was found between shift work schedule and BMI. Thus, other similar studies with a longer follow up period (more than four years) and controlling more confounder factors are necessary to evaluate the relationship between shift work and BMI more accurately.

Abstract
Background and Objectives: Iran started malaria elimination campaigns many years ago. The purpose of this study was to review the malaria surveillance system in Iran.
Methods: The data of this study were obtained from the surveillance system of the Center for Communicable Disease Control, a review of records, documents, books and published articles, and also interviews with process owners and experts of malaria surveillance in 2017-2019.
Results: The surveillance system of malaria in Iran has a coherent structure, in which all identified cases are reported and monitored from the environmental levels to the center by telephone instantly. Considering that the main goals of the malaria program including disease elimination have been obtained, the surveillance system in Iran is currently aiming at strengthening the elimination phase. In this stage, all new cases are also epidemiologically investigated in addition to examination, treatment and follow-up for categorization of the cases in categories of relapse, indigenous, introduced, and induced.
Conclusion: The successful implementation of the surveillance system for malaria over time has caused indigenous cases of disease to be limited to three southeastern provinces of the country and there are fewer than 300 new cases a year. Despite success, since the goal of malaria surveillance in Iran is now disease elimination, continuous monitoring of correct implementation of all processes and evaluation of the applied strategies are necessary.

Abstract
Background and Objectives: Gestational diabetes mellitus (GDM) is a medical problem in pregnancy, and its late diagnosis can cause adverse effects in the mother and fetus. The purpose of this research was to estimate the accuracy parameters of a biomarker for early prediction of gestational diabetes in the absence of a perfect reference standard test.
Methods: This study was conducted in 523 pregnant women who presented to Mahdieh Hospital and Taleghani Hospital affiliated with Shahid Beheshti University of Medical Sciences, Tehran, Iran 2017-2018. As a predictor for detecting GDM, beta- human chorionic gonadotropin (β-hCG) measurements were recorded during 14-17th weeks’ gestation in a checklist. The Bayesian latent variable model was used to estimate the sensitivity, specificity, and area under receiver operating characteristic curve (AUC). Bayesian parameter estimation was calculated using the R2OpenBUGS package in R version 3.5.3.
Results: The median gestational age was 33 years. In the absence of a perfect reference test, the applied model had a sensitivity, specificity, and AUC of 78% (95% credible interval (CrI): 0.66-0.83), 83% (95% CrI: 0.74-0.89), and 0.72 (95% CrI: 0.64-0.88) for β-hCG, respectively.
Conclusion: According to the results of this study, β-hCG may be an acceptable biomarker for early diagnosis of diabetes in pregnant women in the absence of a perfect reference test.

Abstract
Background and Objectives: Cancer is a complex disease with a lengthy and expensive course of treatment that causes many problems for the community. Knowledge of oral cancer plays an important role in early diagnosis. The aim of this study was to determine the level of knowledge about the symptoms and risk factors of oral cancer and assess the related factors.
Methods: In this study, 671 parents of primary school children were randomly selected from primary schools in four districts of Tehran. The participants were asked to answer questions related to demographic characteristics and knowledge of the risk factors and symptoms of oral cancer. Data analysis was done using Poisson regression model and multi-level Poisson regression model using SPSS and STATA software. The AICI Akaike Information Criterion (AIC) was applied to evaluate the models.
Results: The mean score of knowledge was 3.7 with a standard deviation of 6.7. Among the studied variables, female gender, advanced age, a higher SES score, and a higher welfare index had positive effects on oral cancer knowledge (P <0.05).
Conclusion: The results of this study showed that demographic, social and economic factors of parents were effective on oral cancer. It can be statistically concluded that a multilevel Poisson regression model is more suitable for analyzing this data.

Abstract
Background and Objectives: Investigation of child mortality is one of the most important strategies for improving children's health. The purpose of this study was to investigate the age distribution, trends, and projections of mortality in children under 5 years old in Khorasan Razavi province.
Methods: The study population included under-5 mortality data from Khorasan Razavi Province during 2012-2017 extracted from the Causes and Mortality Classification System of Vice-Chancellery of Health, Mashhad University as well as five universities and faculties. Cause of mortality was classified according to the ICD10 codes. Data were controlled using the ANACod software. Descriptive statistics methods and autoregressive integrated moving average (ARIMA) modeling were applied to explore the mortality trend during the time of study using the Minitab.15 and STATA16.
Results: According to the results, the highest mortality rate for children under five was in 2014 and the lowest in 2017. Using the differencing method, the data were stabilized. Finally, the ARIMA model (1,1,2) was identified as a suitable model using the MINITAB software.
Conclusion: The mortality rate of children under five has declined sharply in the last four years in Khorasan Razavi Province. It is predicted that this reduction will continue according to fitted model. However, we are still far from mortality rates in developed and some developing countries; therefore, efforts should be made to reduce the under-five mortality rate by increasing the level of health services, the awareness level of families, and improving maternal and childbirth care.

Abstract
Background and Objectives: Rapid Assessment and Response (RAR) is an approach that has been used in health research since the 1990s, and several guidelines have been designed for it. This study examines and compares different guidelines in this field.
Methods: This review study was conducted on the 6 guidelines published in PubMed and Scopus databases. After the initial review, the main dimensions of these guidelines, including the definition and target group, methods used, steps to conduct the research, and time planning were extracted in the form of a comparative table.
Results: In six guidelines, the RAR approach has been defined in relation to the comprehensive and rapid investigation of a health-related problem. There are differences in terms of the number of 'steps' of rapid assessment and response, as well as in 'time planning'; a period of 12 to 16 weeks is considered. Among the methods used in the reviewed guides, the following can be mentioned: reviewing available information, conducting interviews (open, structured, and semi-structured), focused group discussions, and other methods such as observation, surveys, narrative methods, and mapping.
Conclusion: The rapid assessment and response (RAR) can be used as an approach, with high flexibility and consideration of scientific and practical aspects, to assess health problems and high-risk behaviors in hard-to-reach groups.
