Background: The most important factors of anxiety in individuals are diseases and their treatment. Although anxiety is an alerting process, it can affect quality of life or makes the treatment longer. This study was performed to determine the relationship between level of anxiety and some of individual characteristics in patients with myocardial infarction (MI) in hospitals related to Islamic Azad University, Tehran Medical Unit.
Materials and methods: This study was performed on 200 patients with MI from 3 hospitals related to Islamic Azad University, Tehran Medical Unit. Data were collected with questionnaires, which were filled by interviews. The questionnaire had two parts: 26 questions about some individual characteristics, and the second part comprised Spill Berger standard criteria including 40 questions about anxiety level. "Content validity" method was used for ascertaining validity and "test-retest" method for reliability of tools.
Results: The subjects were all in the age range of 22-34 years with a mean of 25.98. Results indicated that 76.5% of study population was married, 64% had a history of hospitalization due to other causes, and 33% knew about their stress and anxiety. On the basis of total anxiety scores (TAS), 8% of individuals had mild (40-79), 47.5% had moderate (80-119), and 44.5% had severe (120-160) anxiety. There were a direct and statistically significant relationship between the level of anxiety and age, gender, marriage status, occupation, job satisfaction, number of children, adequacy of income, site of living, insurance, living conditions, level of liking their visitors, relationship with other family members, anxiety background among the first degree family members, his/her description of personality, description of family environment, present physical health status, and preference to have information about the illness (P<0.05).
Conclusion: There is a direct and statistically significant relationship between the level of anxiety and individual characteristics of patients with myocardial infarction.

Background: Many studies have been shown association between low level of Adiponectin hormone and insulin resistancy, obesity and increased risk of colorectal cancer. The goal of this study was to evaluate prevalence of polymorphism of Adiponectin gene rs 2241766 in Tehran, Iran and to check the role of this polymorphism in increased risk of colorectal cancer.
Materials and Methods: In this case- control study, genotyping of the Insulin gene were determined in 107 colorectal cancer patients and 107controls by using polymerase chain reaction and restriction fragment length polymorphism genotyping assays (PCR-RFLP).The statistical analysis was done using SPSS ver.16.
Results: Polymorphism of Adiponectin rs 2241766 was not a predisposing factor to increased risk of CRC (p=0.29). The genotype GT compared with TT, was not associated with increased risk of CRC (OR=1.02, CI=0.52-1.97 p=0.95), but GG versus TT (OR=0.015, CI=0.29-0.78 p=0.025) was associated with decreased risk of CRC. Frequency of mutant allele hadn't significant difference between patients and controls (OR=7.34, 95% CI=0.45-1.19 p=0.21).
Conclusion: These findings suggest that polymorphism of adiponectin rs 2241766 isn't associated with increased risk of CRC.

Background: Anxiety, stress, depression and weight problem are the main complications in developing countries that is growing up with growing Technology. Although, mental and weight problem is alerting process, it can effect quality of life or makes longer treatment for the patient’s challenge reduce of power and problem solving or social living and effect to health of Community. The purpose of this study was to evaluate the level of anxiety, stress, depression and their relationship with BMI in nursing students of Islamic Azad University, Tehran Medical Branch between 2010 and 2011.
Materials and Methods: In this correlation study, 300 students of nursing were randomly selected. The data collection instrument was a questionnaire that completed by participants, included two parts: demographic characteristics (age, tall, weight) and DASS 21 standard questions related to anxious, stress and depression level.
Results: Most nursing students had no evidence of anxiety, high stress and depression, and also normal body mass index. There were no significant correlation between BMI and anxiety, stress level and depression.
Conclusion: This study showed most nursing students had no evidence of anxiety, high stress and depression, and also normal body mass index. Also, there were no significant correlation between BMI and anxiety, stress level and depression.
