Abstract
Background and Aim: In angiography, the lens of the eye may be exposed to radiation and cause cataracts. In Iran, at present, only a single film dosimeter is used under the lead-apron to evaluate individual doses. The aim of this study was to investigate the status of occupational radiation as well as the validity of measuring the dose of the whole body of individuals and eye lenses using a single film dosimeter.
Materials and Methods: In this study, the dose of the whole body and eye lenses were measured using a combination of film and thermoluminescence dosimeters for 35 employees of the angiography departments in three selected hospitals under the auspices of Tehran University of Medical Sciences(TUMS). To measure the eye lens dose, three thermoluminescence dosimeter pellets were used on the forehead, and left and right eyes; and to measure the whole body dose using the two-dosimetry method, a TLD card mounted on the chest and on the lead apron and a film dosimeter on the chest and under the lead apron were used.
Results: The angiography personnel's monthly dose mean of the eye lenses and the whole body were approximately 240.6±6.4 μSv and 120.3±3.3 μSv,
respectively(the corresponding amount for the annual dose is less than the levels recommended by international authorities). In addition, the dose ratio of film badge to whole body and eye lens was 0.35 and 0.51, with correlation coefficients of 0.97 and 0.5, respectively. Also, the ratio of eye lens dose to depth dose(TLD) on the lead apron was 1.18 with a correlation coefficient of 0.79.
Conclusion: Using a single film dosimter under the lead apron to estimate the dose of the whole body is almost accurate but this dosimeter alone is not suitable for the assessment of the lens dose of the eye; it is necessary to use an individual dosimeter on the lead apron.

Abstract
Background and Aim: Antibiotics are one of the most commonly used drugs that help to heal and treat diseases, but improper administration and excessive use of them can increase length of stay and cost of hospitalization. The purpose of this study was to analyze relationship between experimental use of antibiotics and duration of stay of premature infants admitted to Mahdiyeh hospital in Tehran.
Materials and Methods: This descriptive-analytical and cross-sectional study was carried out in 2019 on 159 premature infants admitted to intensive care ward of Mahdiyeh hospital in Tehran were investigated. The study tool was a questionnaire that validity of questionnaire was measured by content analysis method and reliability of questionnaire was measured by Cronbach’s alpha method. Data analysis was done using SPSS software, with help of descriptive statistics of frequency and percentage and statistical test of one-way analysis of variance and independent t-test.
Results: The results showed that 52.2% of infants were girls and 79.9% of deliveries were performed by cesarean section. The average length of stay of infants was 31.47 days and average birth of infants was 30 weeks. According to results of study, there was a significant relationship between length of hospitalization of infants with duration of antibiotic treatment and number of periods of receiving antibiotics (P<0.05). The duration of hospitalization of infants with a period of receiving less than 14 days of antibiotics was almost half of duration of hospitalization of infants with more than 14 days of receiving antibiotics. Also, there was a significant relationship between number of antibiotic courses and length of hospitalization of patients (P<0.05). With increase in number of antibiotic sessions, duration of hospitalization of infants increased significantly. The results of study showed that there was a significant relationship between birth weight of babies, cost of bed, and total cost of experimental administration of antibiotics (P<0.05).
Conclusion: Considering that rational use of antibiotics reduce length of stay of hospitalized infants, Ministry of Health should develop an updated and transparent antibiotic adminstration protocol for premature infants and awareness physicians to inform particularly prescription of antibiotics and implementation of stewardship antibiotic programs in neonatal intensive care unit. Also the publication of standard treatment guidelines, instructions including importance of prescribing antibiotics with correct dose and clinical education of physicians are necessary.

Abstract
Background and Aim: Social emergency is intervention programs aimed at preventing social problems by managing social crises. Public awareness of this program plays a crucial role in mitigating such problems. This study aimed to assess the level of public awareness and practice regarding social emergency services.
Materials and Methods: This cross-sectional survey was conducted in 2023 using an online questionnaire and convenience sampling. A total of 706 urban residents of Kerman participated. The data collection tool comprised four sections: demographic information, awareness of social emergency services, awareness of examples of social problems, and practice when encountering social problems.
Results: The mean age of respondents was 36 years, and the majority (70.3%) were women. Regarding awareness, 71% of participants had poor knowledge of social emergency, and 86.7% demonstrated poor awareness of examples of social problems. Additionally, 44.2% exhibited inadequate practice when encountering social problems. The logistic regression analysis revealed a significant association between awareness of social emergency services and both performance and higher education. Individuals with adequate awareness exhibited, on average, 2.28 times better performance than those with inadequate awareness. Similarly, individuals with higher education had, on average, 3.68 times better awareness as compared to those with less than a high school diploma. A significant relationship was also found between awareness of social problems indicators and marital status. Married individuals demonstrated, on average, 0.56 times lower awareness as compared to single individuals. Furthermore, gender and education level were significantly associated with performance. Men’s performance levels were, on average, 1.42 times better than women’s. Additionally, individuals with university and high school education exhibited, on average, 4.22 and 3.47 times better performance, respectively, than those with less than a high school diploma.
Conclusion: Given the poor public awareness of social emergency, there is an urgent need for programs aimed at raising awareness about social problems and the role of social emergency in supporting victims.

Abstract
Background and Aim: Medical university-affiliated dental clinics, particularly those located in metropolitan areas, provide oral healthcare services to a wide range of patients with diverse demographic and socio-cultural backgrounds. The sustainability and continued effectiveness of these clinics largely depend on patients’ satisfaction and loyalty. Understanding the determinants of these two critical factors and exploring their interrelationship is essential for improving service delivery and enhancing patient retention. Therefore, the present study aimed to analyze patient satisfaction and loyalty in a university dental clinic using a structural equation modeling (SEM) approach.
Materials and Methods: This cross-sectional, descriptive-analytical study was conducted during 2023–2024 on a sample of 190 patients who visited the dental clinic of Alborz University of Medical Sciences. Participants were selected through convenience sampling. Data were collected using two standardized questionnaires: one assessing dental patient satisfaction and the other measuring patient loyalty. Structural equation modeling was employed using AMOS software, and model fit was evaluated using standard indices including the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA).
Results: The SEM analysis revealed a significant and positive relationship between patient satisfaction and loyalty (β=0.931, P<0.001). Among the dimensions of satisfaction, hygiene and physical conditions (β=0.939), responsiveness and service delivery (β=0.847), appointment scheduling and waiting time (β=0.761) had the most substantial impact on overall satisfaction (P<0.001). Additionally, attitudinal (β=0.996) and behavioral (β=0.859) components emerged as key dimensions of patient loyalty. Model fit indices demonstrated an acceptable level of fit with the data (CFI=0.893, RMSEA=0.077).
Conclusion: To enhance patient satisfaction and foster loyalty, university dental clinics should prioritize internal operational improvements, particularly in the areas of environmental hygiene, service responsiveness, and time management. Creating a positive mental impression through these factors can serve as a foundational step in cultivating long-term loyalty, ultimately contributing to the clinic’s credibility and sustainable performance within a competitive healthcare environment.

Abstract
Background and Aim: The monitoring of users’ real-time and continuous web searches, in conjunction with the identification of research conducted by experts in a specific field, constitutes the domain of infodemiology. The present study sought to examine the correlation between the demand for health information among users and the scientific output of researchers in elderly health from 2015 to 2024.
Materials and Methods: The present data mining research is of a descriptive-analytical nature, conducted using web mining and scientometrics approaches, employing infodemiology indicators. The web mining section of the study population comprised global user search keywords in the field of elderly health, as examined using Google Trends. In the scientometrics section, the research conducted by researchers in the field of elderly health was analyzed. This research was indexed in the PubMed database from 2015 to 2024. To examine the alignment between users’ information-seeking behavior and researchers’ scientific output, correlation tests were performed using SPSS software.
Results: A rise was observed in the volume of scientific output from researchers and the user search volume index in the field of elderly health on the Google search engine from 2015 to 2024. The monthly mean growth of scientific output from researchers over the ten years was 1439.70. In the user behavior of health information seeking (health information demand), the highest relative search volume index belonged to Ireland, Jamaica, and the United States of America, respectively. The highest number of scientific articles by researchers in the field of elderly health, with 20,480 articles, was related to the year 2021. Also, the average monthly growth of scientific output by researchers in the field of elderly health in this ten-year period (from January 2015 to December 2024) was 1439.70. The investigation revealed a direct and significant relationship (P-value<0.005) between users’ information-seeking behavior and researchers’ scientific output in this field, as determined by applying the Google search engine.
Conclusion: A multitude of factors have the capacity to influence the level of scientific output from researchers in the field of elderly health. In view of the positive relationship that has been observed and the reciprocal relation between the variables of users’ information-seeking behavior and researchers’ scientific output, it can be concluded that the factor of information demand, or users’ internet information-seeking behavior in the web environment, in this area, can be one of the most significant factors. This factor must be given due consideration through rigorous research.

Abstract
Background and Aim: Identifying and transferring lessons learned from past disasters can significantly improve future disaster management performance. Although the general principles of disaster management are similar across events such as earthquakes, context-specific factors, including geographical location, scale and severity of the event, timing, and local characteristics, can shape distinct challenges and, consequently, different management approaches. Therefore, conducting case-based studies that account for the unique conditions of each disaster is essential for effective learning. This study focuses on the Kuhbanan earthquake and aims to identify management challenges arising from the specific characteristics of this region.
Materials and Methods: This study employed a qualitative design using a directed content analysis approach. The study population consisted of experts, decision-makers, and frontline practitioners directly involved in managing the Kuhbanan earthquake. Using purposive sampling with maximum variation, 15 participants were selected from key organizations, including the University of Medical Sciences, the Iranian Red Crescent Society, the Provincial Crisis Management Center, and non-governmental organizations active in rescue and relief operations. Data were collected through in-depth semi-structured interviews, with questions developed based on the dimensions of the STEEPV framework (Social, Technological, Economic, Environmental, Political, and Values). Interviews continued until data saturation was achieved. Data analysis was conducted using MAXQDA software.
Results: Data analysis led to the identification of 42 initial codes, 14 subcategories, and six categories aligned with the STEEPV framework. In the social dimension, key challenges included deficiencies in public and professional training systems (3 codes), weak intersectoral communication and coordination (6 codes), and inadequate responsiveness to community health needs (4 codes). In the technological domain, major limitations were observed in information management (2 codes) and the capacity of technological infrastructure (2 codes). From an economic perspective, financial constraints (5 codes) and welfare-related barriers (3 codes) were identified as influential factors. In the environmental dimension, specific geographical and climatic conditions including mountain topography, fault proximity, and mining operations (4 codes), along with unsuitable physical spaces for disaster management (3 codes), posed major challenges. In the political sphere, a noticeable gap between the government and the public (2 codes) and weak performance of some executive institutions (2 codes) were evident. Cultural and values-related challenges included specific local beliefs (1 code), inappropriate behaviors among communities and relief teams (2 codes), and insufficient consideration of regional culture in rescue and relief operations (3 codes).
Conclusion: This study demonstrated that despite the relatively small scale of the Kuhbanan earthquake, many structural and managerial challenges previously observed in larger disasters were repeated. This finding highlights a chronic weakness in institutional learning and process improvement within the disaster management system. The application of comprehensive analytical frameworks such as STEEPV can assist managers and planners in understanding the complexity and interconnections of different crisis dimensions, moving beyond fragmented and reactive approaches toward more informed decision-making, enhanced stakeholder coordination, and ultimately greater community resilience. It is recommended that the findings of this study be used as a roadmap for revising national disaster management policies and for designing an integrated disaster lesson-learning system.
