Abstract
The popularity of qualitative research in the health sciences is steadily increasing. However individual qualitative research, alone, is unable to provide a comprehensive and broad understanding of the phenomenon under study. This may be the reason why the results of these studies are uncommonly used by health policy makers. Meta-synthesis is a method in which the results of a body of qualitative research are aggregated in order to produce a new and comprehensive interpretation of the studied phenomenon, in such a way that the final result still represents and includes the findings of the original studies. The lack of a comprehensive article in Farsi language in this field, encouraged the authors to write this paper to introduce this method and explain some of its essential components to familiarize health professionals, including researchers and students, with meta-synthesis. In this article, the following components of meta-synthesis are described: the definition, the necessity and the how-to of meta-synthesis a determining research question, the selection and analysis of the original studies, and lastly, meta-synthesis conductors.

Abstract
Background and Objectives: Improving the efficiency and productivity of the higher education, especially in the field of research on health sciences, is one of the characteristics of sustainable development in today's societies. This study aimed to measure the efficiency and productivity of Iran's Medical Sciences Universities (MSU) in the research function.
Methods: In a descriptive study, the research function of fourty five MSUs in Iran was evaluated using data envelopment analysis (DEA) method and Malmquist index in 2010, 2013, and 2016 years. Measurement of both efficiency and Malmquist index was developed and modeled based on the assumption of variable returns to scale (VRS) and output-oriented. Also, the ranking of efficient units was done using Anderson-Patterson's model.
Results: The mean research efficiency was estimated to be 0.86. Findings of Malmquist index showed that between 2010 and 2013, there was a 6% growth in the productivity; while the performance of universities had a 12% drop in research function from 2013 to 2016. Also, the average total productivity during two periods is 0.96, indicating 4% reduction in research efficiency which technology efficiency growth has dropped by 8% and other components of total productivity had a positive growth.
Conclusion: The results of the study showed that universities do not work efficiently and average productivity has been decreasing which was mainly due to a decline in the efficiency of technology, which despite the development of technology in recent years could be the result of the lack of effective use of it.

Abstract
Background and Objectives: A considerable number of clinical trials are conducted in Iran each year. Not much is known about the characteristics of them, this study aimed to investigate key characteristics of Iranian clinical trials.
Methods: All clinical trial protocols registered in IRCT until November 2013 were selected. Text mining techniques were used to extract information from data that was mostly in the textual format. Stata software (v. 11) was used for both extraction and analysis.
Results: Totally 5049 trials where analyzed. Trials were in 40 different areas of medicine and their annual number was increasing. The sample size of registered trials was less than 70 in most trials and showed no significant improvement during the 5-year period (Median sample size= 64, inter quartile range (IQR) = 40-100). Phase III trials comprised 8.4% of the trials with a median sample size of 75 (IQR= 50-120). Of all phase III trials, 69% had a target sample size of less than 100. Most trials used randomization techniques (87.2%) but failed to use placebo (65.3%) and double/triple-blinding techniques (55.8%). The leading sponsors for 99.9% of trials were national bodies and 92.2% of the trials received public funds. Only 1% of the trials were exclusively sponsored by pharmaceutical companies.
Conclusion: The majority of clinical trials conducted in Iran are investigator-initiated and are funded by the public sector. The small sample size and failures in bias control observed in the majority of trials highlights the need for revising current policies of conducting trials in Iran.

Abstract
Background and Objectives: It is necessary to apply appropriate coping methods to reduce destructive physical and psychological effects of stress during Covid-19 pandemics. This study was conducted to explore nurses' experiences of stress coping techniques during the Covid-19 pandemic.
Methods: The present study used a qualitative methodology with interpretive phenomenology method. Purposive sampling was used. The participants, including nurses working in hospitals affiliated to Tehran University of Medical Sciences, shared their experiences through in-depth, individual and semi-structured interviews. The transcripts of interviews were analyzed based on the Dickelmann's approach using the MAXQDA 12 software.
Results: The participants included nine nurses (six females and three males) with a mean age of 45 ± 5.3 years. The results of data analysis showed four main categories and fifteen subcategories conceptually named based on their nature. The main categories were self-support, family shelter, hospital support umbrella, and community support on both extremes.
Conclusion: The participants practiced different coping strategies to deal with stress and anxiety. In addition to individual mechanisms, nurses sought help from other sources of support, such as family, workplace, and community. Based on the experiences of nurses participating in the study, it is recommended to teach nursing staffs coping methods with stress, especially in times of crisis such as the Covid-19 pandemic.

Abstract
Background and Objectives: This qualitative study was conducted to identify reasons for not using condoms by people who inject drugs (PWID) in Iran.
Materials and Methods: Purposeful sampling was applied to recruit four groups [male PWID (n = 14), female PWID (n=6), service providers (n=8), and HIV/Addiction experts (n = 9)] into a qualitative study. Data were collected through focus group discussions (FGDs) or individual in-depth interviews. Data were analyzed using conventional content analysis.
Results: The mean age was 44.0 years for male and 38.2 for female PWID. Qualitative analysis showed 16 themes for not using a condom, which were grouped in three main categories, including knowledge (3 themes), accessibility (4 themes), and individual barriers to use condoms (9 themes). Poor knowledge included low perceived level of risk, insufficient training, and misconceptions. Lack of access to condoms resulted from the country's new policy for population growth control and decrease in the number of pharmacies and harm reduction centers and prisons where condoms were previously distributed free of charge. Common reported individual barriers to condom use were poverty, homelessness, depression, low self-care, and low self-esteem, less pleasure, having sex under the influence of drugs, and stigma.
Conclusion: Both structural and individual factors may play a role as barriers to condom use among PWID.
