ABSTRACTBackground: Annually, about 1.5 million deaths occur due to tuberculosis in the world. The tenth grade is the global burden of diseases and it is expected to maintain its rank by 2020. On the other hand, information about the death and its causes are essential for assessing the health status of the region and analyzing health plans and interventions.Materials and Methods: In this study, data from deaths in Iran from 2006 to 2010 published by the Ministry of Health was used. Death data from tuberculosis during the study period and mortality rates were determined based on age, sex, and residence, and the trend of mortality from tuberculosis was determined. Data analysis was performed using Excel 2016 software.Results: In total five years, 60.7% of deaths were related to males and 39.3% were females. The highest mortality rate was due to pulmonary tuberculosis with 87.7%. Also, death from tuberculosis in urban areas is more than rural areas. In terms of age, the highest number of deaths is in the age group above70 years.Discussion: The results of this study showed that the trend of death due to tuberculosis is decreasing, but this process is very slow. In order to achieve the Millennium Development Goals, basic measures such as education, disease screening, early treatment should be taken into consideration.

Background Today, the majority of developing countries have experienced social, economic, health and the demographic transition (known as aging) problems. Over time, the number of elderly in whole population will increase. Currently, 4%-5% of the whole population are 60 years and older. This study aimed to identify the causes of mortality among the older people over 60 years.Methods & Materials This study is a descriptive cross-sectional study that its study samples included all 60 years and older people who have died in Sabzevar in the years 2011-2013. The study data were collected by checklist.Results A total of 2278 samples were studied. Their mean(SD) age was 71.54(8.87) years and the maximum and minimum ages were 107 and 60 years, respectively. In our study, the average mortality rate due to cardiovascular diseases was 56.24%, deaths due to respiratory diseases 10.37% and deaths due to cancer was recorded as 7.88%, which were the first three leading causes of death in the elderly patients.Conclusion Because the mortality due to cardiovascular disease in the elderly is the first cause and the respiratory infections ranked as the second cause, paying attention to the importance of prevention and observation of risk factors in the families are of critical importance. Also, conducting more comprehensive and adequate planning for early diagnosis of these diseases and particular attention to the patients, especially the elderly persons, are required.

Research development and information technology progress lead to generate big dataset with valuable information. In health research, with tracing people from different dataset like registries can provide valuable information about prognosis, prediction, discrimination, detection or etiology for many outcomes without establishing costly studies. Extracting the knowledge from this potential information is applied using advanced methods such as data linkage or record linkage with deterministic or probabilistic algorithm. However, probabilistic linkage is computationally complex and not well understood by many researchers who may wish to apply it in their work. Therefore, the purposes of this review article is to introduce probabilistic record linkage methodology such as quality and standardization of dataset, determining the matching records from different dataset, calculating the matching weights and discrimination matched from unmatched record using a cut point. In follow, with a practical example the probabilistic record linkage methodology is introduced by cancer registry and mortality dataset.

Background & Objectives: Cardiovascular disease is the main cause of death and disability worldwide and is known as one of the major threats to human health. Therefore, this study was aimed to investigate the changes in mortality from cardiovascular disease in Iran. Materials and Methods: This cross-sectional study was done using analysis of data published in the mortality profile in Iran (29 Provinces) over the years 2006 to 2010. The trend of mortality due to cardiovascular disease in both sexes was drawn during the period of the study according to age groups in the 2010 and their frequency distributions. The WinPepi software was used for data analyses. Results: Evaluation of the mortality profile in Iran (29 Provinces) over the Years 2006 to 2010 is shown that, during these years, the number of deaths from all causes in the country was 1,172,278, which 46.04 percent of them (539,679 cases) were due to cardiovascular disease. Also, according to the data on the mortality from cardiovascular disease, a decreasing trend was observed in the country during 2006 to 2008, while an increasing trend was observed the years 2009 to 2010. Highest number of deaths due to cardiovascular disease was reported in 2006, 115,985 cases, while least number was reported in 2008, 104,126 cases. Conclusion: Because the risk of death from cardiovascular disease increases with ageing, medical interventions for the prevention of cardiovascular disease risk factors in childhood and adolescence and, also, in-time treatment of the patients can be used for preventing from mortality resulted from these disease.
