Background & Objectives: Tuberculosis (TB) is an important issue which its
control is still unsatisfactory at global level. Traditional diagnostic
techniques for active TB diagnosis are inadequate: the diagnostic gold standard
is the cultural exam which suffers from lengthy processing and requires highly
specialized laboratories. Nowadays more specific tests have been recommended.
The aim of this study is to evaluate the performance of Quanti FERON-TB
(QFT)Gold In Tube-Test as a substitute for specific test tuberculin skin test
for diagnosis of latent tuberculosis infection in high risk groups.
Methods: One hundred thirty four (134) individuals who worked in Bo-Ali hospital
(Zahedan) enrolled in this study. They had no active tuberculosis. TST and QFT
tests were performed. The cut-off point of TST was considered based on 15 (mm)
or more indurations as positive. The result of QFT was evaluated by
manufactured guidelines. Multivariate logistic regression was used to identify
the putative risk factors of positive tests.
Results: Proportion of employees with latent TB were 111(82.8%) were positive by
either TST or QFT, and 76(56.7%) were positive by both tests. Agreement between
the tests was high (73.8%, k=0.39 95%CI:
0.21-0.44).
Positive family history of Tuberculosis was significant risk factor for both
positive tests.
Conclusion: This study showed high latent tuberculosis infection
prevalence in hospital workers and high agreement between TST and QFT. Decision
to select one of the tests will be depended on the population, purpose of study
and availability of resources. The results revealed that the QFT can be
appropriate alternative test for high risk group.

Abstract
Background & Objectives: Earthquakes cause thousands of deaths and injuries worldwide every year.
Islamic Republic of Iran has a deadly history of earthquakes. The aim of this
study is to describe injuries rate, causes of injuries, structural
characteristics of buildings and occupant actions immediately after earthquake
in Damghan in 2010.
Methods: This case-study was conducted one week after occurring the
earthquake in five villages of Damghan city in Iran. We used the Physical
Injuries Assessment Questionnaire which was particularly designed for injuries
after earthquakes. Also for acquiring information about region and amount of
losses, some interviews was conduct with local authorities.
Results: Four death and fifty six injuries occurred in five villages of
Damghan city. There were three types of injuries including superficial injuries
(50%), contusions (35%) and fractures (10%). The findings of this study indicating building
structural failure (87.4%), nonstructural factors (7.1%) and trapping (5.3%) seems
the most possible cause of injuries in this region.
Conclusion: This study showed that the building structural failure is the main cause of
injuries (87.4%). Increasing structural
resistance of building especially in village regions and education about
earthquake preparedness should encourage in order decreasing the total number
of people affected by earthquake.

Abstract
Background & Objectives : The length of stay (LOS) is a useful indicator that can be used according to the objective to improve hospital care performance. The purpose of our study was to find factors affecting infants LOS in NICU at Children's Medical Center, Imam Khomeini Hospital, Tehran University of Medical Sciences, using the Cox multiple hazards regression model.
Methods : This historical cohort study reviewed 369 medical records of all NICU admitted newborns at Children's Medical Center in 2009. The required data were collected through a data collection form. The Cox multiple hazards regression model was used to determine the factors affecting LOS in infants who were discharged on the physician‘s order.
Results: The median of stay in NICU was 9 days. Of 369 infants, 272 were discharged with improvement. The results of multiple Cox proportional hazards regression model showed the following factors were associated with LOS in the NICU: prematurity, referral from other hospitals, gastrointestinal diseases and infections, central venous catheterization, mechanical ventilation, and antibiotic therapy (P < 0.05).
Conclusion : Cox proportional hazards regression model should be used when the dependent variable is time and we have censored data. Improving prenatal health care, constructing NICU in hospitals with high risk labor, reduction of preterm birth risk factors, and improving primary health-care services can help us to reduce LOS in NICU.

Abstract
Background and Objectives: Cholera is one of the public health ththat has received attention due to climate change and weather variables. In the current study, the trend of cholera and its epidemics was assessed in the last 50 years in Iran based on climatic variables.
Methods: In a retrospective cohort study, all cholera cases and epidemics of the disease in the country (Iran) were assessed using the registry system of the Center for Communicable Disease Control in the Ministry of Health and Medical education (MOH&ME) from 1964 to 2014. Furthermore, the incidence of cholera was evaluated in 2005-2014 by province. The temperature and rainfall data were obtained from the provincial Meteorological Organization. The correlation coefficient test and mixed-effects binomial regression model were used for data analysis.
Results: A significant positive correlation was found between cholera and rainfall (r = 0.168, P = 0.008). A one-millimeter increase in rainfall increased the incidence of cholera by 10.9% but temperature changes had no effect on cholera outbreaks. The incidence of cholera declined significantly by 14.7% each year from 2005 to 2014. The highest incidence of cholera was reported in Sistan-Baluchestan, Qom, Tehran, Kerman and Hormozgan provinces in a descending order.
Conclusion: In recent years, the the overall incidence of cholera has decreased. The occurrence of cholera is an outcome of rainfall in the previous year. Therefore, increased rainfall increases the number of cholera cases in the next year. However, temperature changes are not related to cholera outbreaks.

Abstract
Background and Objectives: Epidemics of diarrhea caused by contaminated food and water occur frequently worldwide, especially in developing countries. The aim of this study was to identify the factors contributing to the development and spread of diarrhea epidemics caused by Shigella flexneri in Isfahan in the spring of 2015.
Methods: Following the first reports and activation of the surveillance system, a matched case-control study was conducted in 360 cases with diarrhea and 360 controls. Data were gathered using a questionnaire, and conditional logistic regression was used to provide adjusted odds ratios and 95% confidence intervals.
Results: Consumption of contaminated fresh vegetable (OR=4.50, 95% CI=2.88-7.01) was the source of the epidemic. Contact with similar patients (OR=7.19, 95% CI=4.26-12.12), presence of similar patients in the family (OR=33.2, 95% CI=13.64-80.82), food consumption on special events (party, wedding ceremony, funeral, etc.) (OR=1.67, 95% CI=1.06-2.62), being a government employee (OR=3.08, 95% CI=1.64-5.78) and being illiterate (OR=2.91, 95% CI=1.10-7.67) were the risk factors of the spread of the epidemic.
Conclusion: In this study, consumption of fresh vegetable contaminated with Shigella flexneri was the source of the infection. According to the Epidemic Management Team, contamination occurred due to non-standard wastewater irrigation of agricultural lands. Therefore, it is important to consider the standards of agricultural production and compilation of a comprehensive program to improve the status of the wastewater purification system in the environmental sciences by the relevant organizations to prevent diarrhea epidemics.

Abstract
Background and Objectives: Iran has carried out a series of surveys based on the Global school-based student health survey (GSHS) referred to as the CASPIAN. The aim of this paper was to compare the methodology and tools of CASPIAN surveys and to propose recommendations and suggestions for future implementations.
Methods: The data of this systematic review study were gathered from the World Health Organization (WHO) documentations, international databases including Pubmed, EMBASE, Scopus, GoogleScholar, and ScienceDirect, and national databases including Magiran, SID, and Irandoc. The search was conducted in both English and Persian (for the time period from 2003 to 2018). The time and place of the study, target population, questionnaire(s), sample size, and sampling method were compared between the surveys.
Results: Five rounds of CASPIAN survey were conducted in Iran from 2003 to 2015. The surveys had two sets of questionnaires for students and parents. In all five rounds, sampling methods and questionnaires were similar in the core and differed in some details that were added selectively in each round. The questionnaires were designed based on the GSHS and the WHO stepwise approach to non-communicable disease risk factor surveillance (STEPS) programs.
Conclusion: Considering the small variation in each series and compliance with the global model, it is suggested that the next CASPIAN survey be conducted according to the previous series in accordance with the standards presented in the global model in recent years in a reasonable interval from the 2015 survey.

Abstract
Background and Objectives: One of the data sources for monitoring the progress towards Sustainable Development Goals and Universal Health Coverage (UHC) is household surveys such as Multiple Indicator Cluster Survey (MICS) and Demographic and health Survey (DHS). This study was conducted to assess the implementation of these surveys in the Eastern Mediterranean Region (EMR) to evaluate the experience of Iran in conducting these surveys and to propose one of them as the best option for implementation in Iran.
Methods: In this review article, by reviewing the databases of the relevant organizations, the implementation history, instructions, protocols, and the generated indicators of these two surveys were assessed.
Results: So far, 26 standard DHS and 56 standard MICS have been implemented in the EMR. Iraq implemented the highest number of MICS and Egypt carried out the highest number of DHS. In the global reports, no DHS/MICS surveys were conducted in Iran after 2000 However, according to the official reports, Iran conducted two rounds of a survey called MIDHS (a combination of DHS and MICS) in 2010 and 2015.
Conclusion: The EMR has performed well in implementing these surveys. According to the findings, DHS is more suitable for Iran. However, right now, what is important is not to decide which survey to be conducted. Considering the international commitments for monitoring the progress towards UHC, it is important to conduct either one in 2020 in Iran.
