Abstract
Background & Objectives: This investigation was prompted by the growing importance of nested case-control studies and the increasing frequency with which they are done in epidemiologic research. After a brief explanation of nested case-control studies, we evaluate the trends in research methodology over the last decade, especially with regard to cohort, case-control, and nested case-control designs.
Methods: Data for this study were extracted from the PubMed database, using these keywords: Nested Case-Control, Risk-Set Sampling and Density Sampling. The search was confined to the 10-year period from 1996 to the end of 2005. As for other methodologies, we used keywords Cohort and Case-Control for a search over the same time period. The search itself was performed on April 25, 2006.
Results: We found 2011 articles reporting nested case-control studies. There were 95 such articles in 1996 the number had increased to 289 in 2005. Case-control and cohort designs accounted for 68456 and 60479 articles, respectively.
The number of case-control articles rose from 4378 in 1996 to 10270 in 2005, while that of cohort articles increased from 2981 to 9771 over the same period.
Conclusions: The number of cohort and nested case-control articles followed similar upward trends over the last decade and their rate of increase was greater than that of simple case-control articles.

Abstract
Background and Objectives: A pregnancy can be considered high-risk if there are conditions that put the mother or the baby at higher-than-average risk of morbidity or mortality. Neonatal mortality rate is one of the most important indices of children's health status. The present study was conducted to evaluate the effects of high-risk states on neonatal mortality.
Methods: We performed a nested case-control study in the rural areas of Kohgiluyeh and Boyerahmad province. Within the study cohort, 97 cases and 97 controls were selected by a risk-set sampling method. Data were analyzed with univariate and multivariate conditional logistic regression models.
Results: Neonatal mortality was shown to increase significantly in high-risk pregnancies. There were no substantial differences between crude odds ratios and those adjusted for the presence of other risk factors (crude odds ratio decreased from 5.5 to an adjusted figure of 3.25 for pregnancies with one risk factor and from 5.21 to adjusted level of 4.80 for pregnancies with more than one risk factor).
Conclusions: High-risk pregnancies need great attention in family health and prenatal care programs, especially in remote rural areas. Within our rural health network there are potential cohorts for use in nested case-control studies, especially in the evaluation of neonatal mortality risk factors.

Abstract
Background and Objectives: Epidemiology is a tool and a field of science which provides evidences necessary to make decisions. It is known as one of the basic sciences of public health. This study aimed to identify strategies for the promotion of epidemiology by Iranian Epidemiological Association so that people graduated in this field would become able to play an effective and positive role in different parts of the country.
Methods: This study was conducted in 2015. The views and opinions of the members of Iranian Epidemiological Association were collected by email. The views of the members were classified using qualitative methods.
Results: The results of this study helped to identify some of the strategies for the promotion of the position of epidemiology in Iran’s health system by the members of Iranian Epidemiological Association.
Conclusion: Iranian Epidemiological Association can play a more effective role in the promotion of epidemiology in the health system. Effective communication with the members, holding group meetings, advocacy and negotiation, reporting the activities of the Association continuously, identifying national problems and seeking solutions are some of the strategies that can help to enhance the role of the Association and promote the position of epidemiologists in Iran.

Abstract
Background and objective: Epidemiology is a tool and a field of Medical sciences which provides evidences necessary to make scientific decisions. This study aimed to identify strategies for the promotion of the epidemiology by Iranian Epidemiological Association (IrEA) so that people graduated in this field would become able to play an effective and positive role in different parts of the country.
Methods: This study was conducted in 2015. The views and opinions of the members of IrEA were collected by email. The views of the members were classified using qualitative methods.
Results: The results of this study helped to identify some of the strategies for the promotion of the position of epidemiology in Iran health system by the members of IrEA.
Conclusion: IrEA can play a more effective role in the promotion of this field of study in the health system. Effective communication with the members, holding group meetings, advocacy and negotiation, reporting the activities of the association continuously, identifying national problems and seeking solutions are some of the strategies that can help to enhance the role of the community and promote the position of epidemiologists in Iran.

Abstract
To acknowledge the scientific scholars who have contributed to the advancement of knowledge and service without sacrifice to the homeland, it is necessary to to document their biography in a way to highlight their prominent personal characteristics for next generations.
Prof. Abolhassan Nadim, the retired professor of epidemiology and the founder of modern epidemiology in Iran, holding PhD in Parasitology, Epidemiology and Laboratory Sciences, has carried out brilliant activities in the field of epidemiology and health at national, regional and international levels. His activities have been carried out in various areas of epidemiology and health, and his major activities are in various aspects of Leishmaniosis and phlebotomouses distibution. With more than 45 years of service, most of the graduates of epidemiology in the country, directly or indirectly, had been his students.
A glimpse over the great life of Prof. Abulhassan Nadim, shows that the abundant knowledge, the constant effort and the love and interest in the honest service in their lives are the enlightening of the people who are walking in this way.
