    Purpose: To estimate cure rate following graft rejection in bilateral corneal transplants in Iranian patients with keratoconus and to determine risk factors associated with rejection. Methods: In this retrospective study, data were compiled from records of patients who had undergone bilateral penetrating keratoplasty (PK) for keratoconus between 1988 and 2007. In order to estimate cure rate in patients with and without corneal vascularization, we adopted the cure rate frailty model with a Bayesian approach. Results: Two hundred and thirty-eight eyes of 119 patients underwent bilateral corneal transplantion for keratoconus, of which 22.7% experienced graft rejections. Cure rates for patients with and without corneal vascularization were 41% and 79%, respectively. Cure rate decreased 12% per decade of increase in recipient age. The 1, 5, and 10-year survival of corneal transplants without any graft rejection episodes were 82%, 74%, and 70% respectively. Conclusion: The most important risk factor predisposing to rejection in patients undergoing bilateral PK for keratoconus was corneal vascularization. Cure rate for patients without vascularization was high in this data set, indicating that penetrating keratoplasty in keratoconus patients without vascularization is an efficient and reliable procedure

    Plastics bags waste presets serious danger to human and animal health. A descriptive study was conducted on 250 consumers who were shopping in different stores of Kashan city in Iran in 2020 to investigate the consumers’ intention, attitude, subjective norms and perceived behavioral control towards reducing the consumption of plastic bags and using cloth bags based on the theory of planned behavior (TPB). Stratified sampling was applied to select the consumers to filled out a questionnaire developed based on the TPB in Farsi. A path analysis was used to investigate whether attitude, subjective norms, and perceived behavioral control would have any relation with the intention to reduce the consumption of plastic bags and to use cloth bags and whether the pathway model was acceptable. Results showed that certain demographic characteristics such as age and gender affects the perceived behavioral control. Employed consumers had stronger intention in using cloth bags. The path analysis results showed positive correlations between intention and other components of TPB such as attitude, subjective norms, and perceived behavioral control. There was a medium correlation between different dimensions of TPB. Weak correlation was observed between the attitude and perceived behavioral control and maximum correlation was observed between perceived behavioral control and intention. Employed and housewives consumers had strong intentions in using clothe bags. Attitude was not a strong determinant of intention and perceived behavioral control. Thus educational and awareness-raising programs should be accompanied by other reinforcing/ encouraging programs targeting at changing the intention directly. Employed individuals and housewives are more likely to change their behavior and benefit from such programs

    Abstract Background: Heart attacks are the cause of 40% of deaths in Iran and due to its upswing in Iran and the world, the determination of its short-term survival rate in order to assess treatment methods is of great importance. The purpose of this study is to estimate patients’ short-term survival rate after heart attacks by Meta-analysis method. Materials and Methods: This study is a systematic review. The analysis was based on data extracted from English and Persian data bases. To analyze the information obtained, including the average age of patients, and one-month and one-year short-term survival rates, the STATA 11.2 and the random effect model were used. Results: The results of the study on 18 studies entering the Meta-analysis including 62486 patients, demonstrated that one-month and one-year short-term survival rate in Iran are respectively 87.7 and 85.2 percent and no significant difference was observed between the two genders. The average age of patients was reported 62.43 years and no significant difference was observed between the two genders in the occurance of health attack. Conclusion: The results of this Meta-analysis showed that although the survival rate of an Iranian patient after a myocardial Infarction is the same as patients in developed countries, the average age of the patients in Iran is lower, which indicates that the load of disease in Iran is greater than in other countries regarding the years lost to the disease

    Aims: The purpose of the study was to examine the intention of the health ambassadors to receive the COVID-19 vaccine, and investigate predictors of intention using the theory of planned behavior (TPB) and health belief model (HBM). Materials and Methods: This was a descriptive study conducted on 500 health ambassadors. Simple randomized sampling was applied to select the participants. We called the participants and asked them to fill out our 28-item questionnaire. Univariate analyses were used to examine relationships between dependent and independent variables. We used the independent t-test to measure the relationship between quantitatively independent variables and the Chi-square or Fisher's exact test to measure the relationship between qualitative independent variables. Finally, significant independent variables were entered into a hierarchical logistic regression model and the results were interpreted. Results: Overall, 44.8% (224) of participants reported that they have the intention to receive the COVID-19 vaccine. The significant demographic predictors include age, having a chronic disease, Having COVID-19 in the last year, and perceived health status. According to the HBM, the dimensions of perceived susceptibility, perceived benefits, and cues to action. According to the TPB, the dimensions of the subject norm, perceived behavior control, and self-efficacy were significant predictors of vaccination. Conclusion: According to the low rate of COVID-19 vaccination, health educational programs together with encouraging/reinforcing programs may change perceived susceptibility, perceived benefits, perceived behavioral control, and intention. It is better to use various kinds of sources to implement the educational program
