Abstract

Background and Aim: Educating the audience is one of the things that can affect their mental perception of the usefulness and ease of utilizing technology. Due to the lack of knowledge about the unique features and ease of use of Tehran University of Medical Sciences website, some audiences prefer to use the old website and do not accept the changes on the university website well. This research was conducted with the aim of comparing the two methods of face-to-face training and clip training in accepting information technology changes on the university website and evaluating the audience’s awareness of branding features on the web.
Materials and Methods: There were 90 people who participated in this study, 45 of whom received face-to-face training and 45 of them received training about site changes through video clips. Research data collection was done based on Davis questionnaire and data analysis was done using SPSS and Padprism graph software. To compare a quantitative variable in more than two groups, one-way analysis of variance test or Kruskal-Wallis test and also, and also, one-way ANCOVA test were used to check the difference between groups before and after training.
Results: In face-to-face training, variables such as awareness, usefulness and perceived ease of use, as well as attitude and performance regarding the use of information technology before and after face-to-face training or clip did not have significant differences.
Conclusion: Examining the effectiveness of the teaching methods in this project will help the public relations of the university to act quickly for the changes that will occur in the field of web branding in the future, in terms of preparing and accompanying the audience.

Abstract

Background and Aim: This research aimed to study the status of providing health information services in public libraries in Tehran, which was conducted based on the views of librarians working in these libraries.
Materials and Methods: The research method was applied in terms of its purpose and descriptive in terms of data collection, which was conducted as a survey. The statistical population was 150 librarians of public libraries in Tehran. The tool for collecting information was a researcher-made questionnaire. Data analysis was done using SPSS statistical software..
Results: The status of health information resources available in public libraries of Tehran is low and very low in most sources. The level of familiarity of librarians with health and public health issues is %20. The level of familiarity of librarians with selective dissemination of health information services is low and very low with %77.4. The participation rate of librarians in medical information workshops is faced with the non-participation of %70 of librarians. The familiarity of librarians with the services of selective distribution of health information is low and very low. %60 of librarians are not familiar with medical information systems. The percentage of familiarity of librarians with internal medical websites is %60-78 weak. The percentage of familiarity of librarians with foreign international websites in the field of health is average. Librarians consider the main reason for providing selective health information services to improve the level of health literacy in the society. Also, the main obstacle to providing health information dissemination services is the librarian not having enough time to provide services.
Conclusion: The country’s public libraries should consider measures to familiarize librarians with the field of health information and implement policies in this field. Considering the appropriate technical facilities of public libraries in Tehran, it is possible to create and access internal and external health systems and websites. and expanded the sources and documents of librarians’ health information.

Abstract

Background and Aim: One of the basic principles in the safety of drug therapy for patients is the correct registration and labeling of anesthetic drugs, which can lead to the reduction of drug errors, the increase of drug and patient safety, the reduction of drug consumption and the environment, and the optimization of hospital costs.
Materials and Methods: This descriptive-analytical and cross-sectional research was conducted in February 2022 in the operating rooms of Iran University of Medical Sciences hospitals. The participants included 177 Anesthesia experts working in the hospitals’ operating rooms, who were included in the study by census method. The data was collected using the checklist for evaluating anesthetic drug registration and labeling guidelines and analyzed using SPSS software and one-way ANOVA, Fisher, and Pearson correlation coefficient statistical tests. The significance level was considered P value < 0.05.
Results: The average compliance with the guidelines for registration and labeling of anesthetic drugs in all hospitals was 3.559 out of the total score of 16. The average adherence to guidelines in 8 hospitals was significantly different from each other (P < 0.001). Hazrat Ali Asghar Hospital had the highest compliance rate, averaging 10.333 out of 16. Firouzgar and Shahid Akbarabadi hospitals were in the next rank, averaging 10.11 and 6.65, respectively. There was a negative and significant correlation between the level of compliance with the guidelines and the average work experience and age of the experts (P=0/17); However, gender did not significantly correlate with the degree of adherence to the guidelines(P=0/596).
Conclusion: According to the obtained results, compliance with the guidelines for registration and labeling of anesthetic drugs in most hospitals was assessed as weak and at an unfavorable level. Considering the importance of this issue in reducing medication errors and increasing patient safety, it is necessary to use empowerment and retraining courses for Anesthesia experts according to the latest guidelines.

Abstract

Background and Aim: X-ray radiation, besides its useful applications in the diagnosis and treatment of diseases, also has harmful effects. With the increasing demand for various radiographs and X-ray imaging, radiation protection for radiographers is of particular importance. In this regard, a study was conducted to examine the level of awareness, attitude, and performance of radiographers in Iran with regards to the effects of ionizing radiation and protective methods against them.
Materials and Methods: In this descriptive-analytical study, based on a census, the awareness, attitude, and performance of radiographers in 52 cities in Iran were examined by using a questionnaire. Data from 847 radiographers were collected. Finally, the data were analyzed using t-test and analysis of variance through SPSS  statistical software.
Results: Out of the total distributed questionnaires (748 items), 531 questionnaires were completely filled by radiation workers. In the present study, 46% were male and 53% were female, with average scores related to the awareness, attitude, and performance of radiographers in the field of radiation protection being 59.9, 69.4, and 43.54, respectively. There was no statistically significant difference (P<0.05) between the awareness levels of individuals who had undergone refresher training (24.3%) and those who had not. Radiographers’ knowledge of specialized information such as the principle of As Low as Reasonably Available (ALARA) (68.5%), Bucky factor (65.5%), and heel effect (61%), alongside the relationship between source-to-skin distance and radiation intensity (71%), was at a moderate level.
Conclusion: The poor performance of radiologists in this study is not solely attributed to functional deficiencies but sometimes also involves the institutionalization of incorrect principles. These weaknesses and shortcomings are undoubtedly the result of inadequate supervision and erroneous modeling over a long period. If not addressed, they will undoubtedly have irreparable destructive consequences in the future, especially with the increasing advancement of diagnostic radiology methods.

Abstract

Background and Aim: Medical reports and electronic health records are critically important for diagnosis, treatment, patient protection, and medical research. Correcting spelling errors in medical texts is essential to ensure accurate interpretation of information. This research was conducted to automatically correct spelling mistakes in Persian medical texts using neural networks.
Material and Methods: In this study, which was conducted in 2023, a computational model based on artificial intelligence neural networks and dual embedding techniques was developed using Python in a Windows environment. The dual embedding model was fine-tuned for correcting spelling errors in Persian sonography texts. The proposed model employs various techniques for automatic error detection, including dictionary lookup approach and contextual similarity coefficients. Furthermore, features specific to text processing, such as Edit-Distance, along with similarity coefficients, were utilized to automatically select the most appropriate substitute for a misspelled word. The training and testing data for the current model were sourced from a collection of sonography texts from the Imam Khomeini Hospital’s sonography clinic in Tehran.
Results: The proposed model which is based on artificial neural networks, leverages a novel dualembedding architecture to select the best candidate words for correcting both non-word and real-word errors. According to the evaluation results on Persian sonography text, the proposed model achieved an F-Measure accuracy of 90.5% in detecting real-word errors. Furthermore, it demonstrated an impressive 90% accuracy in automatically correcting these real-word errors. Additionally, the model exhibited a strong performance, achieving 90.8% accuracy in correcting non-word errors.
Conclusion: Based on the evaluation results, the proposed method is robust against various changes in word forms and can effectively manage a wide range of morphological and semantic errors, including replacements, transpositions, insertions, and deletions in medical texts. The integration of EditDistance with textual similarity coefficients extracted from the dual embedding model significantly enhanced the accuracy of spelling corrections in Persian sonography texts, ensuring greater validity of such documents. The authors believe that the proposed model represents a significant advancement in the detection and correction of spelling errors in Persian sonography texts.

Abstract

Background and Aim: The term “information behavior,” with an emphasis on health and hygiene, refers to purposeful actions taken to satisfy informational needs related to health. The objective of the current research is to develop and validate a questionnaire on information behavior, with a focus on health and hygiene information.
Materials and Methods: This study was a quantitative research conducted with a tool design approach. Initially, a questionnaire for measuring this behavior was prepared using instrument design methods. The basis for extracting the factors of the present questionnaire has been argumentation and logical repetition. In other words, the researcher, in line with the background of these factors and their repetition in the sources, used them as influential factors in the questionnaire construction. After confirming the content and structural validity, the modified questionnaire was distributed among 238 patients with multiple sclerosis. The sample selection.
was done using the available sampling method. Then, the data were analyzed using exploratory and confirmatory factor analysis. The internal consistency of the data was calculated using Cronbach’s alpha. The collected data were analyzed using descriptive and inferential statistical methods with the help of SPSS and AMOS software.
Results: The content validity of the questionnaire was evaluated with the opinion of 20 experts in information behavior. The reliability of the health information behavior questionnaire was adequate and satisfactory with the overall Cronbach’s alpha coefficient of 0.78 and the Cronbach’s alpha coefficient of the components between 0.71 and 0.94. In order to factor analysis, the sampling adequacy index and the value of Bartlett’s Crowley test were calculated, and all 29 items were statistically significant; which confirms the factorization of the correlation matrix. In the exploratory factor analysis, five factors (avoidance of information), the second factor (need for information), the third factor (exposure to information), the fourth factor (seeking information), and the fifth factor (use of information) were obtained. The indicators of confirmatory factor analysis showed the validity of the proposed structure. The results of the structural equation model test showed that the fit indices were favorable and also indicated the fit of the presented model in the MS patient population.
Conclusion: The obtained results demonstrated that health information behavior in this questionnaire encompasses five factors: information needs, information-seeking behavior, information avoidance, information use, and information confrontation, which were confirmed. The designed scale for assessing health information behavior in the Iranian community has been evaluated and is recommended for use in measuring health information behavior effectively.

Abstract

Background and Aim: There is limited evidence about the effect of the corona disease epidemic on the efficiency of hospitals in Iran. This study was conducted with the aim of investigating the effect of the Covid-19 epidemic on the productivity of public hospitals in Ilam province.
Materials and Methods: This retrospective descriptive research has investigated the performance of 9 hospitals in Ilam province during a four-year period(1397-1400) based on the Pabon Lasso graphic model. The desired data were extracted from the HIS system of the hospitals and the key performance indicators of BOR, BTR and ALOS were calculated. The Pabon Lasso diagram was drawn with Excel software.
Results: The results showed that the bed occupancy percentage in teaching hospitals is significantly higher than non-teaching hospitals (P<0.05). Based on the results, the percentage of bed occupancy and the rate of bed rotation after the covid 19 pandemic has decreased significantly (P<0.05). The average length of the stay of patients also increased after the pandemic (P<0.05). Overall evaluation of hospital efficiency based on the Pabén Lasso model shows that the frequency of hospitals located in Nakara district has decreased from 4 hospitals before the pandemic to 3 hospitals, although hospitals in Kara district have not changed during this period.
Conclusion: Most of the researched hospitals, especially non-teaching hospitals, have low bed occupancy. Weakness in the service delivery chain, especially diagnostic services and specialized and super-specialized services, is one of the main reasons for this situation. Moving towards a change in the way hospitals are managed and having more flexibility in the structure and implementation in the short term and prioritizing large hospitals with a complete chain of services can lead to a way out of the current inefficient situation.

This study aimed to investigate the effect of 12 weeks of resistance training on the serum level of apelin, vaspin, and blood pressure in elderly men with hypertension.
Materials and Methods: In this quasi-experimental study, 24 elderly men with high blood pressure were selected purposefully and based on the inclusion criteria and were randomly assigned to resistance training (N=12) and control (N=12) groups. The participants of the resistance training group performed resistance training for 12 weeks and three days a week. At the beginning and end of the study, blood samples were collected to measure the serum level of apelin and vaspin. Data analysis was performed using SPSS version 24 software with dependent and independent t-tests at a significant level of less than 0.05.
Results: After 12 weeks of resistance training, there was a significant decrease in the serum level of apelin (P=0.002), vaspin (P=0.01), systolic blood pressure (P<0.001), and diastolic blood pressure (P<0.001) as compared to the pre-test. In addition, a significant difference was observed between the two experimental and control groups in the serum level of apelin (p=0.001), vaspin (P=0.001), systolic blood pressure (P<0.001), and diastolic blood pressure (P<0.001).
Conclusion: It seems 12 weeks of resistance training can improve systolic and diastolic blood pressure and regulate the secretion of adipokines apelin and vaspin in elderly men with high blood pressure.

Abstract

Background and Aim: Considering the limitation of resourses, improvement of the hospital efficiency is an absolute necessity. The Covid19 pandemic had a considerable effect on performance indicators of hospitals. This study aimed to investigate changes of indicators of hospitals affiliated to Isfahan University of Medical Sciences before and after Covid19.
Materials and Methods: This study was descriptive-cross sectional. The statistical population included all hospitals under the coverage of Isfahan University of Medical Sciences (38). The input data were related to the three years 2019 to 2021 (the year 2019 as the year before outbreak of Covid-19, the year 2020 as the first year of outbreak and the year 2021 as the second year of outbreak), which were collected using the researcher’s form based on reports extracted from the statistics and hospital information system available in the statistics and information technology management and finally the data analyzed through the PabonLasso model.
Results: Process of indicators during the years 2019-2021 shows that mean of indicators of bed occupancy rate and bed turnover rate as the first year of outbreak of Covid19 (2020) that was the peak of the disease has decreased as compared to the year 2019 and average length of stay has increased. In years 2019, 2020 and 2021, 24.32, 23.68 and 24.32 percent of hospitals were in the third area (efficient area). From 2019 to 2020, efficiency change was observed in 27 percent of the hospitals where 6 hospitals had positive trend and 4 hospitals had negative trend and from 2020 to 2021, efficiency change was observed in 16 percent of hospitals where 2 hospitals had positive and 4 had negative trend.
Conclusion: Considering the low efficiency of hospitals, it is suggested to carry out continuous and annual assessment of efficiency changes in hospitals in order to identify the causes of inefficiency early and preventing its drop and it is necessary for health managers and policy makers to take appropriate measures in the conditions of the outbreak of unexpected disease such as the outbreak of Covid-19 in order to use hospital resources more optimally.

Abstract

Background and Aim: Nursing students are exposed to various educational, family, and social stresses and various factors can affect their mental health. Therefore, in order to pay attention to different dimensions of health and investigate the effects of spirituality on health, the present study was conducted to determine the effect of fasting on the mental health of nursing students of Borujen Faculty of Medical Sciences.
Materials and Methods: The present semi-experimental study with a pre-test-post-test design was conducted in 2022 at Shahrekord University of Medical Sciences. Ninety nursing students of Borujen Faculty of Medical Sciences were selected by available methods and assigned to two intervention and control groups by a simple random method. The intervention in this study included at least 23 days of fasting during Ramadan. The data before and after the intervention were collected by the demographic information questionnaire and the 21-question depression, anxiety, and stress standard tool (DASS). The validity and reliability of this questionnaire were conducted for the first time in Iran by Sahebi et al. in 2005. SPSS  was used for analysis. Descriptive statistical tests including frequency percentage, mean and standard deviation, and inferential statistical tests including t-test, paired t-test, analysis of variance, and chi-square were used.
Results: There was no significant difference in the total mental health score between intervention (32.32±11.62) and control (29.87±14.09) groups before the intervention (P=0.08). There was a significant difference in this score between intervention (20.6±5.71) and control (29.49±8.9) groups after the intervention (P=0.04). The total mental health score in the control group before (29.87±14.09) and after (29.49±8.9) the intervention had no significant difference (P=0.15); while in the intervention group before (32.32±11.62) and after (20.6±5.71) the intervention had a significant difference (P=0.001). Mental health dimensions before and after intervention, indicated that anxiety (P=0.04) and stress (P=0.003) decreased significantly after the intervention in the intervention group. However, there was no significant difference in the depression dimension (P=0.06).
Conclusion: According to the results, it should be said that regular and periodic examination of the health level, and the promotion of educational and training programs on the subject of fasting to improve mental health, should be considered.
