Purpose: This scoping review sought to understand the current knowledge on using digital signatures in implemented electronic health records (EHR). Methods: Our research was carried out on ACM Digital Library, ArXiv, Embase, Engineering Village, IEEE Digital Library, LILACS, Livivo, PubMed/MEDLINE, Scopus, and Web of Science, and gray literature was searched on Google Scholar and ProQuest Theses and Dissertations. Studies related to and associated with using digital signatures and their different types of extensions and forms of storage in EHR worldwide were included. Six authors independently collected the information and assessed the methodological quality of the studies, which quality was evaluated using the JBI Critical Appraisal Checklist. Results: A total of 8,834 studies were initially identified, and 4,592 remained after excluding the duplicated records. Ninety-three studies were selected for the full-text screening phase, and nine studies were included for analysis following the eligibility criteria. Five studies were limited to drug prescriptions, two were associated with using image records and two studies did not specify the digital signature use purpose. The most cited signature storage format was XML. The included studies addressed six signature compression technologies, such as COPRIS and LINCOS, ECDSA, IPFS, and JPEG 2000. Regarding signature storage architecture, seven studies reported remote storage, while only one used local storage. Other two studies associated local and remote storage with in-app storage. Conclusions: Despite the numerous advantages of EHR in health institutions, file security should be a priority in system development, and it still needs to evolve for safe and efficient health data usage. Further research is recommended for developing digital signatures, considering factors such as the time required to store health files. [ABSTRACT FROM AUTHOR]

Abstract: The digitization of health records through electronic health records (EHRs) has transformed the landscape of ophthalmic research, particularly in the study of glaucoma. EHRs offer a wealth of structured and unstructured data, allowing for comprehensive analyses of patient characteristics, treatment histories, and outcomes. This review comprehensively discusses different EHR data sources, their strengths, limitations, and applicability towards glaucoma research. Institutional EHR repositories provide detailed multimodal clinical data, enabling in-depth investigations into conditions such as glaucoma and facilitating the development of artificial intelligence applications. Multicenter initiatives such as the Sight Outcomes Research Collaborative and the Intelligent Research In Sight registry offer larger, more diverse datasets, enhancing the generalizability of findings and supporting large-scale studies on glaucoma epidemiology, treatment outcomes, and practice patterns. The All of Us Research Program, with a special emphasis on diversity and inclusivity, presents a unique opportunity for glaucoma research by including underrepresented populations and offering comprehensive health data even beyond the EHR. Challenges persist, such as data access restrictions and standardization issues, but may be addressed through continued collaborative efforts between researchers, institutions, and regulatory bodies. Standardized data formats and improved data linkage methods, especially for ophthalmic imaging and testing, would further enhance the utility of EHR datasets for ophthalmic research, ultimately advancing our understanding and treatment of glaucoma and other ocular diseases on a global scale.

Introduction: The secondary use of data in clinical environments offers significant opportunities to enhance medical research and practices. However, extracting data from generic data structures, particularly the Entity-Attribute-Value (EAV) model, remains challenging. This study addresses these challenges by developing a methodological approach to convert EAV-based data into a format more suitable for analysis. Background: The EAV model is widely used in clinical information systems due to its adaptability, but it often complicates data retrieval for research purposes due to its vertical data structure and dynamic schema. Objective: The objective of this study is to develop a methodological approach to address the handling of these generic data structures, Methods: We introduce a fivestep methodological approach:1) understanding the specific clinical processes to determine data collection points and involved roles; 2) analysing the data source to understand the data structure and metadata; 3) reversing a use-case-specific data structure to map the front-end data input to its storage format; 4) analysing the content to identify medical information and establish connections; and 5) managing schema changes to maintain data integrity. Results: Applying this method to the hospital information system has shown that EAV-based data can be converted into a structured format, suitable for research. This conversion reduced data sparsity and improved the manageability of schema changes without affecting other classes of data. Conclusion: The developed approach provides a systematic method for handling complex data relationships and maintaining data integrity in clinical systems using EAV models. This approach facilitates the secondary use of clinical data, enhancing its utility for medical research and practice. [ABSTRACT FROM AUTHOR]

Objective Information retrieval (IR, also known as search) systems are ubiquitous in modern times. How does the emergence of generative artificial intelligence (AI), based on large language models (LLMs), fit into the IR process? Process This perspective explores the use of generative AI in the context of the motivations, considerations, and outcomes of the IR process with a focus on the academic use of such systems. Conclusions There are many information needs, from simple to complex, that motivate use of IR. Users of such systems, particularly academics, have concerns for authoritativeness, timeliness, and contextualization of search. While LLMs may provide functionality that aids the IR process, the continued need for search systems, and research into their improvement, remains essential. [ABSTRACT FROM AUTHOR]

To gain a comprehensive overview of the landscape of clinical trials for the H1-receptor antagonists (H1R antagonists) cetirizine, levocetirizine, loratadine, desloratadine, and fexofenadine and their potential use cases in drug repurposing (the use of well-known drugs outside the scope of the original medical indication), we analyzed trials from clincialtrials.gov using novel custom-coded software, which itself is also a key emphasis of this paper. To automate data acquisition from clincialtrials.gov via its API, data processing, and storage, we created custom software by leveraging a variety of open-source tools. Data were stored in a relational database and annotated facilitating a specially adapted web application. Through the data analysis, we identified use cases for repurposing and reviewed backgrounds and results in the scientific literature. Even though we found very few trials with published results for repurpose indications, extended literature research revealed some prominent use cases: Cetirizine seems promising in mitigating infusion-associated reactions and is also more effective than placebo in the treatment of androgenetic alopecia. Loratadine may be beneficial in the prophylaxis of G-CSF-related bone pain. In COVID-19, H1R antagonists may be helpful, but placebo-controlled scientific evidence is needed. For asthma, the effect of H1R antagonists only seems to be secondary by alleviating allergy symptoms. Our novel method to find potential use cases for repurposing of H1R antagonists allows for high automation, reduces human error, and was successful in revealing potential areas of interest. The software could be used for similar research questions and analyses in the future. [ABSTRACT FROM AUTHOR]

BACKGROUND: Nursing education, rooted in conventional methods like didactic lectures and clinical experiences, is evolving to incorporate innovative learning strategies. This study delves into the effectiveness of mind mapping, an interactive technique, in enhancing information retrieval skills among nursing students. Departing from linear note-taking, mind maps visually organize information, aligning with contemporary learning theories emphasizing visual and interactive modalities. MATERIALS AND METHODS: Methodologically, a quasi-experimental design with a crossover intervention was employed, involving 144 nursing students in Pune City, Maharashtra; the time taken to conduct the study was 2 months. The study focused on acquired immunodeficiency syndrome and chronic renal failure (CRF), employing pre-tests, post-tests, and long-term retention assessments. RESULTS: Results indicated significantly higher knowledge gains and retention with mind mapping, substantiated by effect size analyses. Student perceptions, assessed through a Likert scale, revealed widespread agreement on mind mapping’s clarity, effectiveness, and positive impact on understanding and retention. Challenges included the need for faculty and student training, highlighting the importance of integration and support in educational institutions. CONCLUSION: This study explores the effectiveness of mind mapping as a learning technique in nursing education, aiming to enhance knowledge acquisition, retention, and critical thinking skills, departing from traditional approaches. Results indicate that mind mapping significantly improves knowledge retention compared to conventional methods. Hence, we strongly recommend mind mapping as an integral learning technique in nursing education; this will impact on enhancing knowledge acquisition, retention, and critical thinking skills among nursing students, surpassing the outcomes of traditional methods.
