Abstract

Background and Aim: Early diagnosis of pregnancy is very important to prevent fetal damage due to specific drug consumption and high-risk behaviors. The objective of this study was to compare the sensitivity and specificity of quantitative agglutination pregnancy tests in urine and rapid β hCG immunoenzymatic assay test in serum as a gold standard.

Materials and Methods: This cross-sectional study was performed among 390 women who referred to healthcare centers where their urine samples were tested with latex agglutination (direct agglutination and agglutination inhibition) and the results were compared with rapid β hCG immunoenzymatic assay test in serum as a gold standard.

Results: The sensitivity of direct agglutination (82.05 % ) was more than that of agglutination inhibition (81.2 % ), but the specificity of the tests were equal (99.27 % ). The agreement coefficients between direct agglutination and agglutination inhibition on the one hand and rapid β HCG immunoenzymatic assay on the other were 0.859 and 0.853, respectively.

Conclusion : The possibility of negative results in direct agglutination is more than that of agglutination inhibition, but the specificity of both qualitative tests is equal. Besides, both tests may have an equal possibility of false positive results. Since the occurrence of false negative results in qualitative tests is higher than that in serum gold standard, the negative results of such tests should be confirmed with more sensitive methods such as rapid β hCG immunoenzymatic assay.

Volume 15, Issue 6 (Feb & Mar 2022)
Abstract
Background and Aim: Many risk factors can cause biliary system diseases. Hence, this category of diseases is amongst the most common ones. Active patient cooperation is very important in disease management, self-care, and clinical outcomes improvement. A mobile phone application has a high potential in supporting the patients’ self-management. Therefore, this study was conducted to recognize and define data elements to develop a self-care application for biliary patients.
Materials and Methods: The current descriptive study was conducted in 2 stages, resource investigation, and data elements’ need assessment. In the first stage, scientific articles available in databases were used for defining required data elements to develop the application for biliary patients, and a checklist of data elements was prepared. In the second stage, a questionnaire was made based on the checklist. Content and face validity were accepted by the research team and the reliability was calculated 87.2%, using the Cronbach’s alpha test. The mentioned questionnaire was given to Gastroenterologists at Imam Khomeini Hospital complex, and the elected data elements were recognized.
Results: In this application, data elements were categorized into seven sections, including demographic and clinical information, data related to the biliary system diseases, postoperative lifestyle information of the biliary patients, reminders, disease management, and informing. Sixty point five percent of the responders gave the highest importance to data elements in the demographic and clinical data section. Data elements related to patients’ education were considered highly important by 54.2% of the responders. Forty three point eight percent gave the highest importance to data elements in interventional applications’ sections, and only 4.2% gave the least importance to this section.
Conclusion: Based on the identified data elements, a self-care application was designed and developed and can be used as a supplement to specialized care for biliary patients.


Scientific Authority and Medical Research Utilization in Various Scenarios of Access to Information in Iran
Najmeh Nazeri, Ali Shabani, Alireza Noruzi, Mostafa Hossini Golkar,
Volume 18, Issue 6 (2-2025)
Abstract
Background and Aim: One of the pillars of scientific authority is the creation of a process for accessing information, referencing, and applying knowledge. The presence of strong information centers is considered a requirement for supporting this authority. Given the uncertainties of the future, there are various scenarios for accessing information in Iran, each of which requires appropriate measures for the effective application of knowledge. This research aims to understand the needs and requirements of the country’s information sector to achieve scientific authority.
Materials and Methods: Using futures studies methodologies and a combination of quantitative and qualitative methods, the indicators of information centers were first identified. Then, based on expert opinions, measures to achieve scientific authority were determined. The expert panel was purposefully selected from specialists with at least 10 years of experience in relevant fields. Validation of the scenarios and consensus-building were accomplished using an expert panel and focus group.
Results: A conceptual model was identified, comprising five components and 26 factors, which were prioritized based on 10 key drivers. Two critical uncertainties-access and information management, as well as the completion of the information cycle, led to the development of three scenarios: traditional, monopolistic, and democratic. Furthermore, indicators related to scientific authority were estimated based on expert opinions for a ten-year horizon within each scenario. The findings indicated that there was less differentiation among scenarios in the indicators of knowledge exchange and transfer, whereas greater differentiation was observed in the indicators of translation, outsourcing, and knowledge utilization. This highlights the necessity of directing effectiveness toward utility. These changes in the layers of processes and value creation in scientific authority could be traced.
Conclusion: According to the experts’ assessment of the indicators, in the knowledge exploitation stage of the traditional and exclusive scenarios, access to information in the components of knowledge exchange and transfer will not be adequately established. Therefore, to implement knowledge application, the presence of processes for support, promote, and facilitate scientific interaction will play a significant role in establishing scientific authority. Although the dominance of the view of knowledge as power and information as a source of power is expected to continue in the medium term, achieving scientific authority requires a transition to perspectives that offer greater support and provide a better platform for the formation of the information cycle and its broader distribution.
