Background & Objectives: Despite an increased risk of obesity and CHD in people with spinal cord injury (SCI), there is little known about the dietary intake in this group, therefore the aim of this study was to examine nutrient intake and body mass index (BMI) in the spinal cord injury (SCI) population according to level of injury and related variables.
Methods: In this cross-sectional study, 162 patients with spinal cord injury participated from Brain and Spinal Injury Repair research Center, Tehran, Iran. Dietary intakes were assessed by means of a semi quantitative food frequency questionnaire.
Results: The mean age of study population was 34.1±0.6 years. Total energy and carbohydrate intake were higher in men than women (P<0.001). Incomplete injured consumed more MUFA (P=0.03). The elderly were consumed less total calorie, saturated fat, MUFA, cholesterol (P<0.01) and PUFA (P<0.05). Injured patients with longer times had lower total calorie, carbohydrate (P<0.01), total fat and MUFA intake (P<0.05). Based on new classification 60.5% were at the risk of obesity or obese. Central obesity was seen in 33.1%of man and 48.4% of women. BMI of the paraplegia group was greater than that of the tetraplegia group (P= 0.009).
Conclusion: Macronutrients balance is moved towards higher saturated fat intake and less complex carbohydrates and protein intake in SCI patient’s .The elderly and patients who had lived with SCI longer time tended to maintain healthier diets.

Background & Objectives: One of the problems of diagnostic accuracy studies is verification bias. It occurs when standard test performed only for non-representative subsample of study subjects that diagnostic test done for them. In this study we extend a Bayesian method to correct this bias.
Methods: Patients that have had at least twice repeated failures in cycles IVF ICSI were included in this model. Patients were screened by using an ultrasonography and those with polyps recommended for hysteroscopy. A logistic regression with binomial outcome fit to predict the missing values (false and true negative), sensitivity and specificity. Bayesian methods was applied with informative prior on polyp prevalence. False and true negatives were estimated in Bayesian framework.
Results: A total of 238 patients were screened and 47 had polyps. Those with polyps are strongly recommended to undergo hysteroscopy, 47/47 decided to have a hysteroscopy and 37/47 were confirmed to have polyps. None of the 191 patients with no polyps in ultrasonography had hysteroscopy. The false negative was obtained 14 and true negative 177, so sensitivity and specificity was estimated easily after estimating missing data. Sensitivity and specificity were equal to 74% and 94% respectively.
Conclusion: Bayesian analyses with informative prior seem to be powerful tools in simulation experimental

Background and Objectives: Kurdistan Province has always been one of the areas of interest in national disease control programs due to a high number of human brucellosis cases. This study was conducted to explore some of the epidemiological indexes and the trend of the incidence of human brucellosis in this area from 2009 to 2016.
 
Methods: The target population of this cross-sectional study included the human brucellosis patients living in Kurdistan Province whose disease was diagnosed between 2009 and 2016. The data of 6918 patients were analyzed. The incidence was calculated in 100,000 at-risk population.
 
Results: The highest incidence was 103.54 in 100,000 in 2014 and the lowest was 23.86 in 100000 in 2010. According to 8-year analysis, the highest incidence rate was seen in Bijar. Male gender, rural dwellers, farmers, ranchers, housewives, and those aged 24-25 years were at a higher risk of the disease based on the results. Most of the patients reported contact with livestock.
 
Conclusion: Comprehensive measures should be taken to control the infection transmission from domestic animals and their products to humans; moreover, preventing measures should be devised by health policy-makers, especially for villagers, housewives, and men.

Background and Objectives: : According to the global strategy for polio eradication, targeted surveillance of the disease is one of the main tasks of the health system. The purpose of this study was to review the status and surveillance of poliomyelitis/acute flaccid paralysis (AFP) in Iran.
 
Methods: The present study was a review on the processes, structures and achievements of the poliomyelitis/AFP surveillance system in Iran during 2017-2019. The data of this study were obtained from the surveillance system of the Center for Communicable Disease Control; a review of the records, documents, books and published articles; and interviews with process owners and experts of poliomyelitis/AFP surveillance.
 
Results: The polio eradication program in Iran is based on the action plan of the World Health Organization that was introduced initially in 1988. Currently, the surveillance system of AFP is active at three levels: country, university, and city. The number of poliomyelitis cases in the country decreased from 50 cases per year in 1985 to zero in 2001, and Iran has been a polio-free country since 2001. The final report on polio eradication in Iran was approved by the regional commission on polio detection in April 2006.
 
Conclusion: The surveillance system of AFP has had a proper effectiveness throughout the country. Maintaining this situation in the country requires an increase in the sensitivity of the surveillance system of the disease, regular monitoring of vaccine coverage, strict implementation of international health regulations, especially on the eastern borders of the country, and providing technical assistance to neighboring countries.
