Our aim was to make right and informative decision about choosing the most cost-effectiveness heterogeneous infectious waste treatment methods and devices.
In this descriptive study, decision tree analysis, with 10-yr time horizon in bottom-up approach was used to estimate the costs and effectiveness criteria of the employed devices at provider perspective in Iranian hospitals. We used the one-way and scenario sensitivity analysis to measure the effects of variables with uncertainty. The resources of data were national Environmental and Occupational Health Center Survey (EOHCS) in 2012, field observation and completing questionnaire by relevant authorities in mentioned centers.
Devices called Saray 2, Autoclave based, and Newster 10, Hydroclave based, with 92032.4 (±12005) and 6786322.9 (±826453) Dollars had the lowest and highest costs respectively in studied time period and given the 5–10% discount rate. Depending on effectiveness factor type, Newster 10 with Ecodas products and Saray products respectively had the highest and lowest effectiveness. In most considered scenarios, Caspian-Alborz device was the most cost-effectiveness alternative, so for the treatment of each adjusted unit of volume and weight of infectious waste in a 10 year period and in different conditions, between 39.4 (±5.1) to 915 (±111.4) dollars must be spent.
The findings indicate the inefficiency and waste of resources, so in order to efficient resource allocation and to encourage further cost containment in infectious waste management we introduce policy recommendation that be taken in three levels.

The patient decision aids (PDAs), which can facilitate the decision-making process when choosing the optimal method of treatment, are a challenge to patients. This study tried to determine the attitude of physicians on the barriers of using PDAs in the way of prioritizing and proposing solutions to them.
This study was a cross-sectional research carried out on 150 clinical faculty members of research centers and scientific associations affiliated with Tehran University of Medical Sciences. The participants were chosen using the convenience sampling method. The attitude of physicians toward the application of PDAs was interviewed using a self-made questionnaire composed of 23 questions. The association between physicians’ attitude to the use of PDAs and their characteristics was examined using the t-test, analysis of variance, and correlation test.
The mean score of physicians’ attitude was 76.2 (standard deviation =11.9) and the range was 33–107. There was a significant and direct association between the attitude toward the use of PDA and the respondents’ age (r = 0.237, P = 0.007), years of experience (r = 0.205, P = 0.02), being male (P = 0.04), and working in the private sector (P = 0.009). The attitude score of instructors was significantly lower than that of professors (P = 0.02).
The general attitude of physicians toward the use of PDAs was positive. However, apparently as a result of problems mentioned in this study for the developing countries such as Iran, it is much easier to employ these tools in centers run by the private sector. Usage of such tools in public centers necessitates systemic infrastructure as well as credits and budgets required for the training of patients and physicians.

Although most of maternal deaths are preventable, maternal mortality reduction programs have not been completely successful. As targeting individuals alone does not seem to be an effective strategy to reduce maternal mortality (Millennium Development Goal 5), the present study sought to reveal the role of many distant macrostructural factors affecting maternal mortality at the global level.
After preparing a global dataset, 439 indicators were selected from nearly 1800 indicators based on their relevance and the application of proper inclusion and exclusion criteria. Then Pearson correlation coefficients were computed to assess the relationship between these indicators and maternal mortality. Only indicators with statistically significant correlation more than 0.2, and missing values less than 20% were maintained. Due to the high multicollinearity among the remaining indicators, after missing values analysis and imputation, factor analysis was performed with principal component analysis as the method of extraction. Ten factors were finally extracted and entered into a multiple regression analysis.
The findings of this study not only consolidated the results of earlier studies about maternal mortality, but also added new evidence. Education (std. B = −0.442), private sector and trade (std. B = −0.316), and governance (std. B = −0.280) were found to be the most important macrostructural factors associated with maternal mortality. Employment and labor structure, economic policy and debt, agriculture and food production, private sector infrastructure investment, and health finance were also some other critical factors. These distal factors explained about 65% of the variability in maternal mortality between different countries.
Decreasing maternal mortality requires dealing with various factors other than individual determinants including political will, reallocation of national resources (especially health resources) in the governmental sector, education, attention to the expansion of the private sector trade and improving spectrums of governance. In other words, sustainable reduction in maternal mortality (as a development indicator) will depend on long-term planning for multi-faceted development. Moreover, trade, debt, political stability, and strength of legal rights can be affected by elements outside the borders of countries and global determinants. These findings are believed to be beneficial for sustainable development in Post-2015 Development Agenda.

Food security is a multi-dimensional phenomenon. The objective of this study was to identify and prioritize major indices for determining food insecurity in Iran.
Descriptive study using the Delphi method was conducted through an email-delivered questionnaire. Forty-three senior experts at national or provincial level were selected based on their work experience and educational background through study panel consultation and snowballing from Tehran and other cities of Iran. During two rounds of Delphi, participants were asked to identify priority indicators for food security at provincial level in Iran.
Sixty five percent of Delphi panel participated in the first round and eighty-nine percent of them participated in the second round of Delphi. Initially, 243 indices were identified through review of literature; after excluding indictors, which was not available or measurable at provincial level in Iran, 103 indictors remained. The results of study showed that experts identified “percentage of individuals receiving less than 70% of daily energy requirement” with a median score of 90, as the most influential index for determining food insecurity. “Food expenses as a proportion of the overall expenses of the family”, “per capita of dietary energy supply”, and “provision of micro-nutrient supply requirement per capita” with median of 80 were in the second rank of food security priority indicators.
Out of 243 identified indicators for food security, 38 indicators were selected as the most priority indicators for food security at provincial level in Iran.

Background: Myocardial Infarction (MI) is a main cause of death and disability worldwide, which
involves a number of genetic, physiopathologic and socio-economic determinants. The aim of this
study was to assess the patterns of association between education, wealth and some other risk factors
with non-fatal MI in Tehran population.
Methods: Data derived from a second round of large cross-sectional study, Urban HEART-2, conducted
in Tehran in 2011. Out of 118542 participants, all 249 self-reported incident cases of nonfatal
MI were selected as the case group. A number of 996, matched on age and sex, were selected as
controls. Principle component analysis (PCA) was used to calculate wealth index and logistic regression
model to assess relations between the study variables.
Results: Mean (SD) age of participants was 60.25 (12.26) years. A total of 870 (69.9%) of the
study subjects were men. Education, wealth status, family violence, hypertension and diabetes were
observed as independent predictors of non-fatal MI. Overall, as the level of education increased, the
odds of non-fatal MI decreased (p<0.001). We observed an almost J-shaped association between
wealth status and non-fatal MI. No significant associations were found between marital status, BMI
and current smoking with non-fatal MI (p<0.05).
Conclusion: We found different patterns of association between education and wealth with nonfatal
MI among Tehran adults. Lower risk of non-fatal MI is linked to high educated groups whereas economically
moderate group has the lowest risk of non-fatal MI occurrence.

Hookah smoking is growing in popularity especially among women but little is known about the determinants influencing on hookah smoking initiation. In order to address this emerging health risk, a qualitative study was conducted to explore the factors that contribute in the first hookah smoking trial by women.
This qualitative study was conducted during 2012 to 2013 in Tehran, Iran. Participants were recruited to represent diversity in smoking status, ethnicity, age groups and residence. Data was collected through in-depth individual interviews and was analyzed through content analysis.
Four main themes were identified from the qualitative data including: Positive attitude toward hookah smoking; Social and family facilitators; Psychosocial needs and gaps and Sensory characteristic of hookah.
From this study, a variety of factors which contribute to the initiation of hookah smoking among women have been identified. Since one of the major causes of increased hookah smoking may be its ordinary use, all factors causing the ordinary use should be eliminated, and efforts should be made in opposition to hookah smoking promotions.

Background: Studies show that raising news producers’ knowledge and skills
are influential and necessary for promoting the quality of health news. This study aimed
to investigate the barriers to implementing empowerment programs for news producers and to
identify their respective solutions.
Methods: In this qualitative content analysis the opinion of 14 journalists,
one translator, 10 editors or editors-in-chief of health news agencies were gathered
through 12 in-depth interviews and 4 focus group discussions. Purposive sampling was done
and interviews continued up to the point of saturation. Data were analyzed with Open Code
Results: The barriers to the implementation of empowerment programs were
identified as: a) individual factors, b) deficiency of certain facilitators, and c)
organizational and macro policymakings. Various solutions were suggested for the barriers
Conclusion: The implementation of empowerment programs for news producers
requires a system approach toward its determinant factors. This will be more likely if
measures at other concerned levels are also taken. Creating incentives on behalf of the
news-producing organizations can also contribute to this end and create a suitable context
for news producers. Training and empowerment alone will not be sufficient.

Formal knowledge networks are considered among the solutions for strengthening knowledge translation and one of the elements of innovative systems in developing and developed countries. In the year 2000, knowledge networks were established in Iran’s health system to organize, lead, empower, and coordinate efforts made by health-related research centers in the country. Since the assessment of a knowledge network is one of the main requirements for its success, the current study was designed in two qualitative and quantitative sections to identify the strengths and weaknesses of the established knowledge networks and to assess their efficiency.
In the qualitative section, semi-structured, in-depth interviews were held with network directors and secretaries. The interviews were analyzed through the framework approach. To analyze effectiveness, social network analysis approach was used. That is, by considering the networks’ research council members as ‘nodes’, and the numbers of their joint articles - before and after the network establishments - as ‘relations or ties’, indices of density, clique, and centrality were calculated for each network. In the qualitative section, non-transparency of management, lack of goals, administrative problems were among the most prevalent issues observed.
Currently, the most important challenges are the policies related to them and their management. In the quantitative section, we observed that density and clique indices had risen for some networks; however, the centrality index for the same networks was not as high. Consequently the attribution of density and clique indices to these networks was not possible.
Therefore, consolidating and revising policies relevant to the networks and preparing a guide for establishing managing networks could prove helpful. To develop knowledge and technology in a country, networks need to solve the problems they face in management and governance. That is, the first step towards the realization of true knowledge networks in health system.

Background: People are increasingly interested in health news. As a mass media, the ‘Islamic Republic of Iran
Broadcasting’ (IRIB) has the highest number of target audiences. In Iran, some people follow health news via
health programs on satellites and other means of communication. However, all of these programs do not live up
to the standards of scientific evidence. In this study, we examined Tehran people’s trust in health news disseminated
by the IRIB and other mass media outlets.
Methods: A cross-sectional study was conducted in Tehran. Through multistage sampling, 510 households
proportional to size were randomly selected from five regions of Tehran including northern, eastern, western,
southern and central regions. One person from each household completed the questionnaire through interviews.
The questionnaire included questions on people’s level of trust in health news delivered by the IRIB, satellite
programs, the internet and magazines. It also included demographic questions. The validity and reliability of the
questionnaire was evaluated.
Results: Among the interviewees, 50.6% was female. The highest level of trust by the participants was observed
in the IRIB (65.2%), and the lowest trust was observed in satellite news (43.4%); p< 0.001. The interviewees
believed that the IRIB news broadcasters had more mastery over the subject than the ones in satellite
channels (p< 0.001). The IRIB’s coverage of important and relevant health topics was also significantly perceived
to be better than that of satellite news (p< 0.001). According to 83.5% of interviewees, the quality of
health news had improved in the past 10 years. Fifty nine point eight percent of participants believed the quality
and accuracy of the IRIB health news was monitored.
Conclusion: People’s higher level of trust in domestic news as compared to foreign sources and the better status
of domestic sources in other areas such as precision in reporting, coverage of more important news, its delivery
in lay language, the news broadcasters’ proficiency, and other cases - from the participants’ point of view -
can highlight the significance of designing interventions for changing health behavior among domestic health
news producers. Therefore, the results of this study can prove useful to health news policy makers in the IRIB.

Background: The current study aimed to determine eye care utilization, to assess the role of economic inequality in the utilization of eye care services, and to identify its determinants in Shahroud, North of Iran.
Methods: Of the 6,311 invited people, 5,190 (82.24%) individuals aged 40 to 64 years old participated in the study. A history of a visit by an ophthalmologist or optometrist was considered as eye care utilization. The gap between low- and high-economic groups was decomposed into its determinants using the Oaxaca decomposition method.
Results: Among the participants, 16.32% [95% Confidence Intervals (CI)= 15.31–17.33%] had never been examined by an ophthalmologist or optometrist, and 30.94% (95% CI= 29.69–32.20%) had not undergone an eye examination in the past 5 years. This negative history was significantly higher among female subjects [Odds Ratio (OR)= 1.79, 95% CI= 1.51–2.14], the low-economic group (OR= 2.33, 95% CI= 1.90–2.87), the visually impaired (OR= 1.41, 95% CI= 1.05–1.90), and the uninsured (OR= 1.93, 95% CI= 1.45–2.58). The negative history of eye examination decreased with increasing in age (OR= 0.94, 95% CI= 0.93–0.96) and education (OR= 0.94, 95% CI= 0.92–0.96). In this study, 24.72% (95% CI= 22.30–27.14) of the low-economic group and 9.94% (95% CI= 8.75–11.14) of the high-economic group had no history of eye examination. Decomposition of the gap between the two economic groups showed that education and gender were the most important determinants of inequality.
Conclusion: A considerable percentage of adults, even those with visual impairment, do not receive appropriate eye care. There is a definite economic inequality in the community for which poverty per se could be the major cause.

The nature of community-based participatory research (CBPR) poses distinctive ethical challenges. In the absence of organized guidelines, a remarkable amount of researchers’ time and energy will be spent tackling these ethical challenges. The study aimed to explore ethical issues and principles potentially arising when conducting CBPR.
This qualitative study conducted in CBPR Center of Tehran University of Medical Sciences. Required data were gathered through systematic literature review and semi-structured interviews. Representatives of community, academia, and nongovernmental organizations (NGOs) participated in our study. Ten interviews with representatives of partner organizations, four group interviews with academic staff, and four with representatives of community were conducted. Repeated thematic analysis was used to elicit ethics-related overarching themes from transcribed interviews. As recommendations, these themes were then organized into a set of CBPR-related ethical issues and principles.
Four CBPR ethical guidelines (including 173 articles) were selected from a systematic review. Overarching themes relating to ethical principles which emerged from interviews were as follows: Trust, transparency and accountability, equity and inclusion, power imbalance, tolerance and conflict management, and attention to cultural sensitivity. Practical principles that emerged included: Consensus rather than informed consent, ownership of data and research achievements, and sustainability and maintenance of relationships. According to findings and in comparison to international guidelines, the present study put more emphasis on cultural sensitivity and sustainability as CBPR ethical tangles.
Community-based participatory research ethical challenges are of the same kind in most parts of the world. However, some discrepancies exist that calls for local scrutiny. Future use and critic of current explored ethical issues and principles are highly encouraged.

Background: Hypertension is an important public-health challenge worldwide. The prevalence of hypertension greatly varies across countries. The aim of this study was to estimate the prevalence of self-reported hypertension and to determine related factors in a large random sample of Tehran population in 2011.
Methods: In this cross sectional study, 69173 individuals aged 25–64 years were selected using multistage cluster random sampling method. All participants were interviewed by trained personnel using standard questionnaires. Weighted prevalence and incidence rates were calculated and principle component analysis (PCA) was used to construct wealth index. Chi-square and odds ratio were used to assess associations in univariate analysis. Logistic Regression model was used in multivariate analysis.
Results: The prevalence of self-reported hypertension was 5.27% in total, 3.83% in men and 6.64% in women (p< 0.001). The annual incidence rate of self-reported hypertension was 6.87 per 1000; 5.26 in men and 8.43 in women (p< 0.001), obviously varied across various districts. In multivariate analysis, age, sex (woman), marital status (single), obesity and smoking were positively associated with prevalence of self-reported hypertension. Education level was negatively associated to hypertension. On the other hand, wealth status was not associated to self-reported hypertension.
Conclusion: Our study findings highlighted low awareness rates of hypertension among Tehran adults especially in men and younger people. Hence, we recommend public health strategies to improve health education programs. Moreover, programs to develop the surveillance system and screening programs to early detection of undiagnosed cases are urgently needed particularly in high risk population subgroups.

A serious worldwide effort to strengthen research based knowledge translation (KT) has begun in recent years and some countries, particularly developed ones, are trying to incorporate KT in their health and health research systems. Keeping in mind the recent economic depression and the need to perform more efficient research, we aimed to assess and compare the KT status of selected health research institutes in the Eastern Mediterranean Regions' countries, and to identify their strengths and weaknesses in the field.
After finding the focal points that would steer the focus group discussions (FGDs) and help complete the ‘Self Assessment Tool for Research Institutes’ (SATORI) tool, each focal point held two FGDs in which researchers, research authorities and other individuals specified in detail further in the study were held. The scores obtained by each institute were evaluated quantitatively, and the transcriptions were analyzed qualitatively with OpenCode software.
For ease of analysis the 50 items of the SATORI were classified into 7 main domains: ‘priority setting’, ‘research quality and timeliness’, ‘researchers’ KT capacities', ‘facilities and pre-requisites of KT’, ‘processes and regulations supporting KT’, ‘interaction with research users’, and ‘promoting and evaluating the use of knowledge’. Based on the scoring system, the strongest domain was ‘research quality and timeliness’. ‘Priority setting’ was the weakest domain of all. The remaining domains were more or less equal in strength and were not in a favorable state. The qualitative findings confirmed the quantitative findings.
The main problem, it seems, is that a KT climate does not exist in the region. And despite the difference in the contexts, there are many similarities in the region's institutes included in this study. Collaborative efforts can play a role in creating this climate by steering countries towards KT and suggesting regional strategic directions according to their needs.
The aim of this study was to determine the socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles in Kurdistan Province, west of Iran, 2009.
The data used in this study was collected from the data gathered in non-communicable disease surveillance system (NCDSS) in 2009 in Kurdistan. A total of 1000 people were included in this study. The outcome variable of this study was the nonuse of seatbelts and helmets. The socio-economic status (SES) was calculated based on participants’ residential area and assets using Principal Component Analysis (PCA) method. The concentration index, concentration curve, and comparison of Odds Ratio (OR) in different SES groups were used to measure the socioeconomic inequalities using logistic regression. In order to determine the contribution of determinants of inequality, decomposition analysis was used.
The prevalence of nonuse of seatbelts in cars and helmets on motorcycles were 47.5%, 95%CI [44%, 55%], respectively. The Concentration index was -0.097, CI [-0.148, -0.046]. The OR of nonuse of seatbelts in cars and helmets on motorcycles in the richest group compared with the poorest group was 0.39, 95%CI [0.23, 0.68]. The results of the decomposition analysis showed that 34% of inequalities were due to SES, 47% were due to residential area, and 12% were due to unknown factors.
There is a reverse association between SES and nonuse of seatbelts in cars and helmets on motorcycles. This issue must be considered while planning to reduce traffic accidents injuries.

Magnetic resonance imaging (MRI) is an expensive and commonly used technology with a variety of indications in patient diagnosis and treatments. The aim of this study is to identify a comprehensive list of indications and contraindications for MRI in patients with low back pain (LBP) and to determine the appropriateness of using this technology in these patients on the basis of this list.
A cross-sectional study was conducted in four radiographic centers in Tehran, Iran. A list of MRI indications and contraindications for LBP was developed by review of documents and expert panel. A pre structured checklist was designed and incorporated into a structured form. All 100 consecutive patients referring to four radiographic centers for performing MRI regarding LBP completed the questionnaire. Chi-square, Fisher's Exact Test and logistic Regression were used to assess statistical significance.
In this study, 187 patients (46.7%) had an indication for MRI, but 186 patients (46.5%) had no indication, 18 patients (4.5%) had indication and contraindication at the same time and nine patients (2.3%) had contraindication. Moreover, 71 patients (17.8%) underwent MRI for LBP during the past 2 years, of which 14 (19.7%) had normal results. Patients with complementary private insurance had a history of previous MRI about 20% more than other patients (P = 0.018). There was a statistically significant relationship between complementary private insurance coverage and number of MRI performed (P = 0.006).
About half of the patients referring to radiographic centers with LBP for MRI had no indication for this test.

Childhood obesity is a world-wide health problem and development of interventions to prevent or control it is a priority. Obesity is prevalent and on the increase among school-students in Iran, too. As the first step for development of an intervention, the current study was designed to complete our understanding of ideas, attitudes, beliefs, and preferences of primary school children in Tehran, Iran.
Twenty-seven primary school-students (11 boys, 16 girls) in grade-five, most of whom were overweight or obese, participated in four focus-group discussions (FGDs). All FGD notes were analyzed to find the main themes.
Nine themes in three main categories emerged after analysis. The themes in the category of barriers of losing weight included environmental, psychological and physiological barriers. Category of intervention components included nutrition improvement, physical activity promotion, social support and education. Setting and deliverer of the intervention were included in the intervention conditions category. The children proposed a multi-component approach for development of an intervention. They mentioned nutrition and physical activity improvement, social support and education as the main elements of an effective intervention.
The findings indicate that obese children need to be supported against different barriers of losing weight, mainly social barriers, especially humiliation by the community.

Upon successful experiences of family physician program in the rural regions, Iranian Ministry of Health and Medical Education (MOHME) made a decision to expand this program to urban areas. For this reason a pilot program were designated and some cities have been selected to determine dos and don’ts of performing family physician program in the cities. Various studies were published during this period demonstrating the advantages and disadvantages of family physicians’ care in these cities. After this process in 2012 and 2013 MOHME announced implementation of family physician program in Tehran. Our study investigated public attitudes, knowledge and practice about the newly introduced program.
This cross-sectional study was performed in Tehran during November to December 2012. A telephone survey was carried out using the Random Digit Dialing (RDD) method and data was gathered by a researcher designed questionnaire. A total of 386 residents aged 18 years and over participated in the study. To compare the differences between various groups’ knowledge scores data were analyzed performing Chi-square test, t-test, ANOVA, and logistic regression by SPSS software version 17, to find factors that affected individuals’ agreement with the program.
Among all samples 214(57.4%) knew about the program and almost 120(85.1%) of these aware people were planning to participate in the program. Television and Radio were the major information resources. After adjusting for Educational status, Access to Internet and Socio Economic Status(SES) those people who didn’t have any kind of health coverage systems(Health insurance) were most likely to accept the program and agree with that[OR= 2.38(1.05-5.38)].
The fact that despite low levels of information, most of aware people intend to enroll in the new program reveals that expanding informative programs would bring more participation and involvement among community.

Maternal mortality ratio (MMR) is one of the main indicators of the millennium development goals and its accurate estimation is very important for the countries concerned. The objective of this study is to evaluate the applicability of capture-recapture (CRC) as an analytical method to estimate MMR in countries.
We used the CRC method to estimate MMR in Iran for 2004 and 2005, using two data sources: The maternal mortality surveillance system and the National Death Registry (NDR). Because the data registry contains errors, we defined three levels of matching criteria to enable matching of cases between the two systems. Increasing the matching level makes the matching criteria less conservative. Because NDR data were missing or incomplete for some provinces, we calculated estimates for two conditions: With and without missing/incomplete data.
According to the CRC method, MMR in 2004 and 2005 were 33 and 25 in the best-case scenarios respectively and 86 and 59 in the worst-case scenarios respectively. These estimates are closer to the ones reported by United Nations Agencies published in 2010, 38 and Hogan's study, 30 in 100,000 live births in 2005.
The MMR estimation by CRC method is slightly different from the international studies. CRC can be considered as a cost-effective method, in comparison with cross-sectional studies or improvement of vital registration systems, which are both costly and difficult. However, to achieve accurate estimates of MMR with CRC method and decrease the uncertainty we need to have valid databases and the absence of such capacities will limit the applicability of this method in developing countries with poor quality health databases.

Computed Tomography (CT) is a useful diagnostic technology, particularly in accident and emergency departments.
To identify a comprehensive list of indications for application of CT in patients with minor head trauma (MHT) and to determine appropriateness of its use on the basis of this list.
Materials and Methods:
A cross-sectional study was conducted in three Imaging centers in Tehran. A panel of experts developed a list of CT indications for MHT by reviewing documents. A pre-structured checklist was designed and incorporated into a structured form. Four hundred consecutive patients referring to three imaging centers for performing CT due to MHT completed the questionnaire.
Of 400 patients who underwent CT after MHT, 187 (46.8%) patients had Glasgow coma scale (GCS) score of 13 or 14 at two hours post-trauma and 37 (19.8%) of these patients did not have any indication of imaging. In addition, 213 (53.2%) patients had GCS score of 15 out of which 110 (51.6%) patients did not have any indication of imaging. Patients with a GCS score of 15 had a noticeably lower proportion of abnormal CT results in comparison to patients with a GCS score of 13 or 14, (odds ratio, 19.07; 95% confidence interval, 6.74-54.00; and P < 0.001). There was a statistically significant association between abnormal CT results and the presence of indications including vomiting, dangerous mechanism of injury, visible signs of trauma above the clavicles, signs of skull base fracture, and suspected skull fracture (P < 0.001).
On average, about 37% of the patients with MHT referring to the emergency departments had no indication of CT and approximately 86.5% of CT results were normal. Improving this situation can result in a significant saving in health care costs.

Despite significant reduction in global disease prevalence, leprosy still has a high rate of disability while its determinants are unfair and many of them are amendable. The objective of this study was to measure inequality of disability in leprosy in Iran.
This was a cross-sectional study (2006-2007) on all living people affected by leprosy registered in W. Azerbaijan province health center, Western North of Iran. The outcome of the study was the socio-economic inequality considering presence or absence of grade 2 disability (G2D) based on the WHO classifications. An extended concentration index decomposition approach was used for analysis.
Among 452 cases, 65.3% were male and 67% were affected by the multi bacillary type. Overall G2D was 65.3%. The estimated Concentration Index was −0.0782, showing presence of pro-poor socio-economic inequality of G2D, while extended CI estimation (ѵ = 5) was −0.163. Achievement index with coefficient (ѵ = 5) revealed that G2D mean was 16% more than classic mean in the poorest group. The result of decomposition of the existing inequality revealed that, some of the determinants such as receiving mono-therapy, education, urbanization, and bacillus calmette guerin (BCG) vaccination had shared contribution (67.4%, 61.8%, 59.2%, and 57.5% respectively).
This study provided new perspective for the health system to leprosy control considering the significant gap between rich and poor (inequality) regarding G2D disability, and its effective elements in socio-economic strata. Some effective actions can be considered to reduce the scale of existing inequality.

In Iranian Traditional Medicine, mizaj (temperament) plays a key role in preventive, therapeutic and lifestyle recommendations. A reliable self-reported scale for mizaj identification is critically needed to introduce ITM into the official medical and health care system especially in the case of designing national preventive protocols.
The present study aimed to design a preliminary self-administered mizaj questionnaire and assessed its reliability and validity in Iran.
Patients and Methods
In this cross-sectional study, a questionnaire with 52 items was designed based on mizaj-related indices. Subsequent to content and face validity assessment, using qualitative and quantitative method, 47 items remained. Based on the non-randomly sampling, the test-retest reliability of each question and internal consistency of the questionnaire was examined by the participation of 35 volunteers. The reliable version questionnaire was filled up by 52 volunteers wherein they were divided into warm/cold and wet/dry groups based on their mizaj which was predetermined by a team of expert practitioners. Logistic regression analysis was performed for validity process between the experts’ assessment of mizaj and each of the items in the questionnaire that resulted to the final ten-item questionnaire divided into two subscales. By using ANOVA and post Hoc with Dunnet statistics, the optimum cut-off points were defined and their sensitivity and specificity was assessed.
The weighted kappa coefficients of the 39 items were between 0.40 and 0.82 showing their acceptable reliability and the Cronbach’s α coefficient was 0.71 showing the internal consistency. The sensitivity and specificity of the final questionnaire cut-off points were 65% and 93% for the warm group, 52% and 97% cold group, 53% and 67% dry group and finally 53% and 76% wet group.
Our results suggested that many of the designed questions according to the literature’s mizaj identification indices had satisfactory reliability and the final ten-item questionnaire could discriminate the different groups of mizaj, therefore, this can be used as the first version of a brief self-report mizaj estimating scale.

The objective of this study was to investigate the application of the university research findings or commercialization of the biopharmaceutical knowledge in Iran and determine the challenges and propose some solutions.
A qualitative study including 19 in-depth interviews with experts was performed in 2011 and early 2012. National Innovation System (NIS) model was employed as the study design. Thematic method was applied for the analysis. The results demonstrate that policy making, regulations and management development are considered as fundamental reasons for current commercialization practice pattern. It is suggested to establish foundation for higher level documents that would involve relating bodies and provide them operational guidelines for the implementation of commercialization incentives.
Policy, regulations and management as the most influential issue should be considered for successful commercialization. The present study, for the first time, attempts to disclose the importance of evidence input for measures in order to facilitate the commercialization process by the authorities in Iran. Overall, the NIS model should be considered and utilized as one of the effective solutions for commercialization.
