Background:Various studies have shown a seasonal pattern in suicide in the developed societies; however, this pattern is not taken into consideration in most countries including Iran.Objectives:The current paper studied the seasonal pattern of committing suicide in Northern Iran.Materials and Methods:The present study was a longitudinal study with time series features. Subject included suicide attempts recorded by emergency wards of all hospitals in Mazandaran province, Iran. The variable time, in this study, was defined as each month of study years (2005 - 2011), which included 84 monthly time points. To analyze data, the Student’s independent t-test and analysis of variance (ANOVA) test were used.Results:Of the 14,437 suicide attempts reported during the seven-year period, 5359 (37.1%) were related to males. Suicide attempts reached a peak in June (1418 cases) and November (1352 cases), but were at their lowest level in March (991 cases) (P = 0.877).Conclusions:The suicide seasonality range is broad in this part of Iran. Moreover, there were two noticeable suicide peaks in June and November.

Introduction: Hypertension is a chronic disease that causes a great deal of harm to the individual, which is the leading cause of disability and death worldwide, accounting for one eighth of all deaths. This disease is not treatable but it is manageable. Therefore, this study aimed to investigate factors related to hypertension based on health belief model in Yazd. Methods: This descriptive cross-sectional study was performed on 400 people over 30 years old in Yazd city. Sampling was done by cluster method. Subjects were included in the study according to the address of the headers. Questionnaires were completed by self-report and interview. Data collection tools were demographic questionnaire, awareness questions and health belief model. SPSS 15 software was used for data analysis. Statistical indices, Mann-Whitney U test, Kruskal-Wallis and Spearman correlation were used to analyze the results. Results: The mean and standard deviation of age were 44.08 ±11.6 years. There was a significant relationship between demographic variables of age, gender, occupation, education, marital status and history of hypertension in relatives. Among the constructs of health belief model, only the perceived barriers showed a significant relationship with blood pressure (P <0.01). Conclusion: Since there is a significant relationship between perceived barriers and hypertension, it is suggested that future interventions be designed to reduce perceived barriers (No need to change lifestyles, lack of time for physical activity, cost of regular blood pressure control, and no family accompanying diet changes) and blood pressure control.

Chronic renal failure (CRF) is an irreversible kidney condition that leads to end-stage renal disease (ESRD) [1]. ESRD patients require replacement interventions, such as kidney transplant or hemodialysis. Globally, ESRD is a substantial issue in the medical field. In the absence of replacement interventions for these patients, ESRD leads to death [2]. There were about 3,730,000 patients in ESRD by the end of 2016. Taiwan, Japan, and the United States have the highest ESRD prevalence in the world [3]. In Iran, ESRD prevalence is 610 per million people, which is greater than the global
