Abstract
Background and Aim: Cervical cancer is the fourth main cause of mortality among women, and annually about half a million new cases are detected in developed countries. Based on oncological studies, human papillomavirus (HPV) is classified into two categories: high-risk type and low-risk type, and most cases are related to the high-risk type of human papillomavirus. HPV 16 and 18 are among the more dangerous ones in this type of cancer. Human papillomavirus is a small group of uncoated viruses with double-stranded DNA that belong to the papillomaviridae family.
Materials and Methods: In this review study, more than 200 articles related to human papillomavirus and immune system function against this virus were reviewed from 2015 to 2020 and among them, 34 articles related to markers and cytokines in cervical cancer were chosen from Google Scholar, Scopus, and PubMed.
Results: One of In-vitro methods in markers detection , is using vectors to infect dendritic cells to present antigen, increase the expression of markers and mature T cell, which leads to the identification of a variety of markers and cytoklines such as PD, PDL, CD, MHC, FASL, IFN, IL, TLR associated with cervical cancer.
Conclusion: Cervical cancer prevention can reduce the economic as well as the social burden of having the disease in the community. Important cytokines expressed when exposed to HPV include IL-6 and IL-8. Several agonist epitopes with enhanced binding power to the human leukocyte antigen (HLA-A2) A2 class I antigen have been described to enhance cytotoxic T lymphocyte responses and to be used in the development of effective HPV vaccines; this is because it has already been shown that different epitopes of 16 HPVs, such as E6 and E7, are able to elicit human cytotoxic T lymphocyte (CTL) responses by binding to HLA-A2.

Abstract
Background and Aim: Hospital managers are one of the key decision-makers in the implementation of health information systems. This study aimed to determine the implementation challenges of health information systems based on the hospital managers’ perspective.
Materials and Methods: This descriptive-analytical study was conducted in 2019 on the hospital managers of three provinces (Kerman, Yazd, Sistan and Baluchestan). Data were collected using a self-administrated questionnaire. The face validity of this questionnaire was approved by experts in health informatics and health information management and its reliability was confirmed by Cronbach’s alpha (α=96.7%). Data were analyzed using SPSS. To investigate the relationship between the mean of each challenge with demographic variables, Pearson, Independent T-test, and ANOVA tests were used.
Results: In this study, the factors related to ignoring the hospital manager’s needs in system selection (1.333 out of 2 points), hardware purchase cost, insufficient user training to using the system (1.238), inadequate manpower and health informatics specialists (1.19), software purchase cost, insufficient financial resources (1.142), high cost of system launching, the lack of integration and interoperability among information systems, lack of support from health care professionals (1.047), and lack of management experience in choosing the best system (one out of 2) had the highest scores (out of 2 points). Also, personnel training costs to work with the system (-0.092) and Lack of improvement in work processes (-0.047) obtained the lowest scores. Data analysis showed that managers with clinical backgrounds considered financial and human challenges more important than non-clinical managers (P<0.031).
Conclusion: The hospital managers believed that financial, human, technical, managerial, and organizational factors are the most important challenges in implementing health information systems in Iran’s hospitals respectively. The health policy-makers and planners at large and small levels can address many of the challenges before implementing systems by focusing on identified priorities.

Abstract
Background and Aim: Hospital library services are among the basic infrastructures for promoting e-health readiness. This study evaluated the components of e-health readiness in hospital libraries in Isfahan.
Materials and Methods: This is an applied-descriptive survey. The statistical population is 10 government hospital libraries in Isfahan city. The questionnaire completers are the managers of the aforementioned libraries. The research tool is a researcher-made questionnaire that was prepared by a deep and comprehensive review of related literature. The 61-question questionnaire is based on the Likert scale and has four sections: learning readiness (R1), core readiness (R2), social readiness (R3), and technology readiness (R4). To determine the content validity of the questionnaire, the opinions of professors, specialists, and experts were used and its validity was confirmed. Its reliability was confirmed using Cronbach’s alpha of 0.83. Descriptive statistics were used to examine the data.
Results: Isfahan government hospital libraries are in a good state in terms of learning readiness with a score of 3.77. They were in a moderate state in terms of core readiness with a score of 3.49. Social readiness with a score of 2.47 and technology readiness with a score of 2.48 were reported as poor state. “Literacy level of technology and services related to health care” component with a score of 2.9 from the core readiness, “reimbursement policies” component with a score of 1 from the social readiness, “resources training” component with a score of 1.8 from the learning readiness, and “organization access to ICT education” component with a score of 1.35 from the technology readiness were identified as weak components. In general, all government hospital libraries in Isfahan are in a moderate state in terms of e-health readiness.
Conclusion: Hospital libraries face various challenges in joining the e-health category, including a lack of readiness in the technology sector. The lack of appropriate policies for implementing e-health in libraries, lack of users’ skills in using information and communication technology, users’ ignorance of the e-health services needed in the library, lack of professional human resources, and lack of e-health-related training for users are some of the weaknesses of hospital libraries in the e-health readiness sector.

Abstract
Background and Aim: Neonatal hypoxic-ischemic encephalopathy (HIE) is a clinical syndrome characterized by impaired brain function resulting from oxygen deprivation and reduced cerebral blood flow. Developing predictive models can serve as valuable tools for physicians in forecasting disease outcomes and facilitating early interventions. The present study was conducted with the aim of constructing a predictive model for neonatal hypoxic-ischemic encephalopathy using data mining algorithms.
Materials and Methods: This applied study was conducted using a descriptive approach. In the first stage, the factors influencing the prediction of neonatal hypoxic-ischemic encephalopathy were identified through expert surveys. In the second stage, data pertaining to 4,000 neonates were collected from the Iman system, available in the database of the Ministry of Health and Medical Education, during the years 2020–2021. Following preprocessing, a dataset comprising 3,962 records with 13 features was extracted. Subsequently, predictive models were developed using algorithms including artificial neural networks, decision tree variants, random forest, support vector machines, logistic regression, and Bayesian networks. Model construction was performed using the Python programming language within the Anaconda environment. Finally, performance evaluation and comparison were carried out using metrics such as accuracy, precision, specificity, F1-score, and the Area Under the Curve (AUC).
Results: The findings of the study revealed that the Area Under the Receiver Operating Characteristic Curve (AUROC) for models developed using logistic regression, artificial neural networks, random forest, Bayesian networks, support vector machines, and decision trees were 86%, 86%, 84%, 82%, 76%, and 74%, respectively. The highest performance was achieved by the logistic regression algorithm, with an accuracy of 81%, sensitivity of 85%, and specificity of 96%. The greatest sensitivity was observed in logistic regression, artificial neural networks, and support vector machines, whereas the naïve Bayesian algorithm demonstrated the lowest performance metrics. In the predictive model for hypoxic-ischemic encephalopathy, the most influential feature was the first-minute Apgar score, while the least influential factor was delivery outside the hospital.
Conclusion: The findings of the present study indicated that the predictive model for neonatal hypoxic-ischemic encephalopathy based on the logistic regression algorithm demonstrated superior performance. It is anticipated that the application of practical data-driven algorithms for neonates with hypoxic-ischemic encephalopathy will play a crucial role in the rapid identification of the condition and the provision of appropriate treatment. Such approaches can enable healthcare professionals to act within the critical window of opportunity, thereby improving the quality of care, preventing disease progression, and reducing the severity of adverse outcomes.

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.
