      Medical Subject Headings (MeSH) is one of the most important vocabularies for information retrieval in medical research. It enables fast and reliable retrieval of research on PubMed/MEDLINE, the world's largest body of medical literature. The original English version of the thesaurus can be accessed via a MeSH Browser developed by the NLM. Recently, a multilingual MeSH Browser was proposed to enable usage across languages. To improve upon the original system, a new user interface (UI) was developed using contemporary web design frameworks in combination with principles from cognitive science. It aims to simplify access for medical professionals and increase overall usability. Evaluating such design improvements continually is necessary to quantify the possible positive impact for online systems in medical research. This study therefore directly compares the resulting system to the NLM Browser, using an established online questionnaire. Results show significant improvements in content and navigation as well as overall user satisfaction, while offering feedback for future improvements. This underlines the benefits of employing contemporary web design in terms of usability and user satisfaction.

      preVIEW is a freely available semantic search engine for Coronavirus disease (COVID-19)-related preprint publications. Currently, it contains >43 800 documents indexed with >4000 semantic concepts, annotated automatically. During the last 2 years, the dynamic situation of the corona crisis has demanded dynamic development. Whereas new semantic concepts have been added over time-such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of interest-the service has been also extended with several features improving the usability and user friendliness. Most importantly, the user is now able to give feedback on detected semantic concepts, i.e. a user can mark annotations as true positives or false positives. In addition, we expanded our methods to construct search queries. The presented version of preVIEW also includes links to the peer-reviewed journal articles, if available. With the described system, we participated in the BioCreative VII interactive text-mining track and retrieved promising user-in-the-loop feedback. Additionally, as the occurrence of long-term symptoms after an infection with the virus SARS-CoV-2-called long COVID-is getting more and more attention, we have recently developed and incorporated a long COVID classifier based on state-of-the-art methods and manually curated data by experts. The service is freely accessible under

      BACKGROUND: Despite the disproportionate impact of the novel coronavirus on Black Americans, there is little research that centres Black college students' information behaviours during the pandemic.OBJECTIVE: The objective of this study is to identify information needs, resources and use regarding the novel coronavirus pandemic among Black American college students.
    METHODS: This is a quantitative study among 389 college students in the USA. Data were collected using an online crowdsourced survey instrument. Descriptive and inferential statistics were used to analyse data through SPSS.
    RESULTS: The most salient information needs related to Covid-19 symptoms, personal protective equipment, vulnerable populations, and risk assessment; however, students also wanted information on Covid-19's impact on the Black community. There were no statistically significant gender differences in students' information seeking, resources or use with one exception; male students believed the internet alone could provide all relevant information about the coronavirus in comparison to female students. Barriers related to the volume of information, information fluidity and determining the quality of information.
    CONCLUSION: Colleges and universities can play a critical role in information dissemination during crisis events. Students need critical information literacy skills that intersect with everyday information needs, particularly health literacy.

      The context of digital library has changed from insufficient information to information overload, and its corresponding service mode should also change from "people looking for information" to "information looking for people." Using a grounded theory approach, this paper extracts 78 initial concepts, 24 basic categories, and 6 main categories by coding and analyzing the raw data obtained from the interviews. On this basis, the relationship path and action mechanism between categories are discovered; based on which a theoretical model of the influence mechanism of digital library intelligent information recommendation service satisfaction is constructed. The research results have shown that, under the moderating effect of user preference, the quality of data mining system, recommendation information quality, recommendation service quality, and recommendation form together have an impact on the satisfaction of digital library intelligent information recommendation service. The results of our work can provide useful reference for the optimization and healthy development of digital library services. Meanwhile, it has some theoretical and practical contributions. How to quickly obtain the information people required from a large amount of information is particularly important. Personalized construction is an inevitable service trend for the development of digital libraries in the new era. We in this paper study the current situation of digital libraries and the development of personalized services in digital libraries. We focus on data mining-related technologies, the development of digital library data exploration technologies, and the provision of Internet application services. The problems in this area were summarized, and the countermeasures were put forward based on this. It can be concluded that the concept of a digital library is not just a collection of data with information management tools, it is an environment that brings together collections, services, and people to support the entire data flow. It converts information into domain knowledge, from creation to dissemination. It guides the process from use to save. The trial registration number is ChiCTR2200055403.

      Plantar fasciitis and calcaneal spur are common causes of heel pain in the community. People use the Internet to obtain medical information about diseases. We reviewed Internet information sources on plantar fasciitis and calcaneal spur for quality and readability. The first 50 websites for each search term ("calcaneal spur", "heel spur", and "plantar fasciitis") were scanned on . Six different valid tools were used for information quality and readability assessment. We searched for HONCode (Health On the Net Foundation Code) stamps on included websites. The total mean points for DISCERN were 50.52 ± 14.62, and the total mean points for JAMA (Journal of the American Medical Association) were 2.42 ± 1.26. In total, 25.72% of 97 websites had HONCode stamps. The average scores for the readability indicators were calculated to be Flesch-Kincaid Grade Level (FKGL): 7.27 ± 1.71, Gunning Fog: 8.46 ± 2.17, Simple Measure of Gobbledygook (SMOG): 6.89 ± 1.24, and Coleman Liau Index: 15.56 ± 1.85. In our study, when the website resources were examined, there were profit websites the most and website quality and readability were moderate level. A significant proportion of the websites have a financial bias and provide low-quality information. A mechanism for monitoring the quality and readability of online information must be established and managed systematically.

      BACKGROUND: Breast density has become a topic of international discussion due to its associated risk of breast cancer. As online is often a primary source of women's health information it is therefore essential that breast density information it is understandable, accurate and reflects the best available evidence. This study aimed to systematically assess online international breast density information including recommendations to women.METHODS: Searches were conducted from five different English-speaking country-specific Google locations. Relevant breast density information was extracted from the identified websites. Readability was assessed using the SHeLL Editor, and understandability and actionability using the Patient Education Materials Assessment Tool (PEMAT). A content analysis of specific recommendations to women was also conducted.
    RESULTS: Forty-two eligible websites were identified and systematically assessed. The included informational content varied across websites. The average grade reading level across all websites was 12.4 (range 8.9-15.4). The mean understandability was 69.9% and the mean actionability was 40.1%, with 18/42 and 39/42 websites respectively scoring lower than adequate (70%). Thirty-six (85.7%) of the websites had breast density-related recommendation to women, with 'talk to your doctor' (n = 33, 78.6%) the most common.
    CONCLUSIONS: Online information about breast density varies widely and is not generally presented in a way that women can easily understand and act on, therefore greatly reducing the ability for informed decision-making. International organisations and groups disseminating breast density information need to ensure that women are presented with health literacy-sensitive and balanced information, and be aware of the impact that recommendations may have on practice.

      BACKGROUND: YouTube™ is considered a convenient and popular platform to seek healthcare information, which is uploaded by people of various professions.OBJECTIVES: This study aimed to assess the content and the quality of the YouTube videos containing information about vitamin D for children.
    MATERIAL AND METHODS: A YouTube search was performed using the terms 'vitamin D for children' and 'vitamin D deficiency in children'. Two independent reviewers scored the videos with the use of a customized 11-point scoring scheme and the 5-point Global Quality Scale (GQS) to assess the content and the quality of each video. The videos were further classified into poor, moderate and good videos. The Kruskal-Wallis and χ2 tests as well as Spearman's correlation coefficient were used for statistical analysis.
    RESULTS: In a total of 120 videos screened, 70 videos were included. They had a median content score of 4 and a median GQS score of 3. According to the information included in the videos and their overall quality, most of the videos were categorized as moderate (n = 33; 47.14% and n = 32; 45.71%, respectively). Good-quality videos had statistically significantly higher content scores as compared to the other groups (p = 0.001). A positive correlation was found between the content score and the GQS score (ρ = 0.434; p = 0.001).
    CONCLUSIONS: Most of the videos on YouTube about vitamin D were rated as moderate according to the sufficiency of the information and also their overall quality. This suggests that health organizations need to make further efforts to create good-quality medical content on popular social media platforms, such as YouTube.

      AIM: To investigate the reliability and educational value of YouTube videos of minimally invasive complete mesocolic excision with right hemicolectomy procedures.MATERIALS AND METHODS: We searched YouTube with the terms "Laparoscopic and Robotic Complete Mesocolic Excision with Right Hemicolectomy" on January 12, 2021. To assess the reliability of the videos, we evaluated nine steps in each video and scored the videos based on the key steps they contained. The videos were divided into three groups according to the source of the upload. The total number of views, length, time since upload, and the number of likes, dislikes, and comments were recorded for each video. Narration, the use of descriptive subtitles, and the upload status by an expert surgeon were also examined.
    RESULTS: Sixty-eight videos were included in the study. A positive significant correlation was identified between the comprehensiveness score (CS) and the number of views (p=0.025). The CSs of the videos accessed from academic channels, as well as those accessed from journals, congress, and association channels, recorded higher CSs than those obtained from the personal channels of consultants (p=0.003). It was also found that CSs were higher in the videos of expert surgeons (p<0.001) and narrated videos (p<0.001).
    CONCLUSION: Not all YouTube videos on this subject have reliability and educational value. Surgical videos on YouTube may be evaluated by a video review commission formed by academic institutions, surgical associations, or expert surgeons, and videos suitable for education could be brought together and published via a free channel.

      Background: As the internet usage becomes easily accessible, the patients are more frequently searching about diseases and medical/non-medical treatments. Considering that complex regional pain syndrome (CRPS) is a debilitating disease, it is important to check the information that patients are accessing. Therefore, this study aimed to investigate the reliability, sufficiency, and accuracy of the YouTube videos about CRPS.Methods: This study is a descriptive research which is derived by searching videos using the keyword 'complex regional pain syndrome' on YouTube. Relevance-based sequencing was used to sort the videos. Sources and video parameters were documented. To evaluate the accuracy, reliability and content quality of the videos, Global Quality Score, Journal of American Medical Association Benchmark Criteria and Modified DISCERN Questionnaire scales were used.
    Results: A total of 167 videos were included in this study. The majority of the videos originated from USA (80.2%, n = 134). The median number of views was 639 and the viewing rate was 73.3. Most of the videos had partially sufficient data and the interaction index viewing rate parameters for videos with high content quality were greater than videos with low content quality (P = 0.010, P = 0.014).
    Conclusions: Our results showed that videos about CRPS on YouTube mostly had partially sufficient data and include intermediate-high quality contents. Moreover, high-content quality videos had higher viewing rates, interaction indexes, number of likes, longer durations, as well as better reliability and accuracy scores. Videos with high quality and reliable content are needed to reduce misinformation about CRPS.
