Abstract
Background and Aim: To describe the trends in research articles in the field of mental health.
Materials and Methods: The articles that we reviewed belonged to the fields of psychiatry, psychology, and neuroscience. We limited the search to the literature published over the 30-year period from 1973 to 2002. The following types of data were extracted: areas of research, specific topics, study design, location for data collection, funding sources, and the different types of working relationship among the authors.
Results: Analysis of publication trends in 3031 articles showed a marked increase in the total number of publications with time, especially over the last 5 years. As for different research areas, we detected a growing proportion of articles in the field of neuroscience and a decline in articles dealing with mental health. The volume of research in the fields of psychology, epidemiology and clinical sciences remained relatively constant. There was a rise in the proportion of cross-sectional studies and clinical trials in the second half of the 30-year period.
Conclusion: It is important to find the reasons and implications for the waning interest in mental health. Our results could provide an empirical basis in policy making and strategic planning for research in this area

Abstract
Background and Aim: In 1991, the world health organization initiated a project to simultaneously develop an instrument for measuring quality of life in 15 countries. The study yielded two questionnaires, namely WHOQOL-100 and WHOQOL-BREF. These were intended as generic QOL measurement tools to be used in a broad range of diseases, for different degrees of disease severity, and in various cultural subgroups. The objective of the current study was to evaluate the Iranian version of the WHOQOL-BREF. This 26-item instrument comprises four domains: Physical Health, Psychological, Social Relationship, Environment and the overall QOL/health.
Material and Methods: We administered the questionnaire to 1167 adults in Tehran. The stratified sample consisted of 476 diseased subjects and 700 healthy ones. We tested the instrument's reliability (internal consistency, test-retest), discriminant validity and factorial structure.
Results: The participants had an age mean of 36.3 years (SD = 13.2) and had an average 11.5 years of education. Using Cronbach's α and intraclass correlation, all domains met the minimum reliability standards, with the exception of social relationship domain (α = 0.55). The latter could be attributed the small number of questions in this domain and the sensitive nature of the questions themselves. Since 83% of the questions show maximum correlation with their original domain, the factorial structure of the questionnaire was regarded as acceptable. The questionnaire has the ability to discriminate different groups after adjustment for confounding factors in regression analysis.
Conclusion: This study demonstrated good to excellent reliability and acceptable validity in various groups of subjects in Iran. The instrument may be used in future studies, albeit with minor modifications in the domain of social relations, as determined by expert opinion.

Abstract
Background and Aim: In the past few years publications in the field of medicine have increased considerably in Iran and knowledge production in this country shows the greatest growth rate in the entire Middle East region. Considering the fact that 12% of all faculty members in the health and medical sector in Iran are employed by Tehran University of Medical Sciences, this university is regarded as the country's leading research institution. This study is focused on the behavior of the researchers in this university in terms of collaboration in research and factors that affect such behavior.
Materials and Methods: Our samples included all research projects in Tehran University of Medical Sciences that had obtained grants from inside and outside the university in 2004, had registered their contracts, had been finished by the time of this study (October 2006- March 2007) and whose final reports had been submitted (315 projects). The data collecting forms were filled for 301 files. The researcher's questionnaire was sent to the principal investigators of the projects and eventually 208 questionnaires were collected. We used the SPSS software package and the usual statistical tests (frequency ratio, chi square, analysis of variance and multiple linear regression with the Enter method) to assess the factors affecting the participation scores of individuals. Based on the data gathered from the forms, we used the UNICET software to analyze the 'cooperation network' between project directors and their principal co-workers and the relationship between different sections of the university.
Results: Only in 2.2 percent of the projects whose contracts were arranged in 1383 there has been some cooperation between the project director/principal coworkers and non-academic organizations. This ratio reaches 2.5% for collaboration with other universities. Among all projects, health system research programs show a better status of collaboration. Linear regression analysis showed that another important factor affecting the participation score is the "method for choosing the research topic". University-affiliated research centers only collaborate with the Schools of Medicine and Public Health, while in the School of Rehabilitation and Physical Medicine all projects are defined within the School's own structure, with virtually no collaboration with any other sections of the university.
Conclusion: The present study showed that research programs in this university include little collaboration with organizations outside the university or with other universities. Part of this is related to the current structure of the research sector in the country, which is largely financed by the government with hardly any participation by the private sector. Current potentials within the University make it possible to embark upon joint research initiatives with other academic institutions. As the possible effect of intervention on health system research has been shown, policies can be implemented to promote effective collaborative research at university and national level.

Abstract
Background and Aim: During the COVID-19 pandemic public health measures and protocols such as regular hand washing and wearing a face mask were recommended at the national level. The implementation of these health protocols reduced the prevalence of respiratory diseases, but no study has been conducted to investigate the impact of the implementation of these protocols on the spread of viruses that are transmitted through fecal-oral route. Considering that non-polio enteroviruses (NPEVs) are mainly transmitted through fecal-oral route, this study was conducted to determine the prevalence of non-polio enteroviruses in patients with acute flaccid paralysis (AFP) in Iran before and during the COVID-19 pandemic.
Materials and Methods: To detect non-polio enteroviruses stool samples of AFP cases received by Iran National Polio Laboratory in 2019 (before the COVID-19 pandemic) and 2021 (during the COVID-19 pandemic) were tested. To isolate NPEVs by cell culture, the WHO standard protocol was used, and the TaqMan One-Step Real Time PCR was used for molecular testing.
Results: In 2019, a sample of 21 out of 1070 patients and a sample of 12 out of 100 patients were found to be positive for non-polio enterovirus by cell culture and the molecular method, respectively; these ratios decreased to10 out of 678 and 3 out of 100 in 2021.
Conclusion: Based on the findings of this study, it can be concluded that the observance of personal hygiene and public health protocols during the COVID-19 epidemic have, in addition to the general reduction of respiratory transmission of viruses, also affected the faecal-oral transmission of viruses.
