      The novel coronavirus disease (COVID-19) has caused a pandemic and global health crisis. Although normal operation and services in many libraries have been greatly disrupted, academic libraries in the United States were reportedly responding to challenges by pivoting to new ways to meet the users' needs. This observational study was designed to investigate the status, services, and resources disclosed via websites of academic medical/health sciences libraries (MHSLs) in the United States and document how they adapted and continued to provide support to help fight the health crisis and the resulting "infodemic" through various means. A complete list of members was obtained from the website of the Association of Academic Health Sciences Libraries (AAHSL). The U.S.-based AAHSL member institutions were included in this study. Each American academic MHSL website and its associated webpages were browsed; web contents were categorized and analyzed based on four research questions proposed by this study. A descriptive analysis was conducted to summarize all findings. A total of 157 AAHSL member institutions were included in the study. These libraries spread all over the United States, and 90% of them announced closures of library buildings and facilities. A significant number of MHSLs quickly adapted to the evolving situation and transitioned their services and instruction to the online environment. The COVID-19 information sources adopted by MHSLs included the following ranked by frequency from high to low: The U.S. government agencies such as Centers for Disease Control and Prevention and National Library of Medicine, the World Health Organization, publishing communities, professional journals, organizations, local institutions, government agencies, and news channels. In addition, MHSLs undertook a series of actions to support academic communities and local healthcare professionals including resource curation, clinical care support, education, and outreach to the public. Through library guides, MHSLs provided comprehensive and customized search queries to help researchers locate the latest and relevant publications to COVID-19, curated multiple data resources and data exploration, and visualization tools, and selected the latest biomedical and health evidence in a wide range of topics. Other featured resources and services were associated with ethical issues (i.e., racism and prejudice), educational and entertainment information (e.g., virtual tours of parks), and personal experience documentation. This observational study is the most recent investigation and documentation on the status, services, and resources of the academic MHSLs in the United States during the initial U.S. outbreak of the COVID-19 pandemic. Although the current health crisis is taking a heavy toll on libraries nationwide, MHSLs are still managing to play a vital role in supporting the academic communities, healthcare facilities, and the general public and fighting against the pandemic and the resulting information crisis.

      This article aims to review the important roles of health knowledge organization systems (KOSs) during the COVID-19 pandemic. Different types of knowledge organization systems, including term lists, synonym rings, thesauri, subject heading systems, taxonomies, classification schemes, and ontologies are widely recognized and applied in both modern and traditional information systems. Apart from their usage in the management of data, information, and knowledge, KOSs are seen as valuable components for large information architecture, content management, findability improvement, and many other applications. After introducing the challenges of information overload and semantic conflicts, the article reviews the efforts of major health KOSs, illustrates various health coding schemes, explains their usages and implementations, and reveals their implications for health information exchange and communication during the COVID-19 pandemic. Some general examples of the applications, services, and analysis powered by KOSs are presented at the end. As revealed in this article, they have become even more critical to aid the frontline endeavors to overcome the obstacles due to information overload and semantic conflicts that can occur during devastating historic and worldwide events like the COVID-19 pandemic.

      The current coronavirus disease 2019 (COVID-19) pandemic is making fundamental changes to our life, our society, and our thinking. The substantial influx of information on disease updates, case analysis, suggestions, and recordings leads one to contemplate what information professionals and information scientists can contribute to shorten the pandemic, improve human lives, and build a more impactful profession. This viewpoint examines concepts related to misinformation and discusses the responsibilities of information scientists, especially in the context of independent thinking. It suggests that research on and education in information science could help to develop independent thinking and train independent thinkers.

      Comprehensive genome annotation is essential to understand the impact of clinically relevant variants. However, the absence of a standard for clinical reporting and browser display complicates the process of consistent interpretation and reporting. To address these challenges, Ensembl/GENCODE1 and RefSeq2 launched a joint initiative, the Matched Annotation from NCBI and EMBL-EBI (MANE) collaboration, to converge on human gene and transcript annotation and to jointly define a high-value set of transcripts and corresponding proteins. Here, we describe the MANE transcript sets for use as universal standards for variant reporting and browser display. The MANE Select set identifies a representative transcript for each human protein-coding gene, whereas the MANE Plus Clinical set provides additional transcripts at loci where the Select transcripts alone are not sufficient to report all currently known clinical variants. Each MANE transcript represents an exact match between the exonic sequences of an Ensembl/GENCODE transcript and its counterpart in RefSeq such that the identifiers can be used synonymously. We have now released MANE Select transcripts for 97% of human protein-coding genes, including all American College of Medical Genetics and Genomics Secondary Findings list v3.0 (ref. 3) genes. MANE transcripts are accessible from major genome browsers and key resources. Widespread adoption of these transcript sets will increase the consistency of reporting, facilitate the exchange of data regardless of the annotation source and help to streamline clinical interpretation.

      Academic collections, such as COVID-19 Open Research Dataset (CORD-19), contain a large number of scholarly articles regarding COVID-19 and other related viruses. These articles represent the latest development in combating COVID-19 pandemic in various disciplines. However, it is difficult for laypeople to access these articles due to the term mismatch problem caused by their limited medical knowledge. In this article, we present an effort of helping laypeople to access the CORD-19 collection by translating and expanding laypeople's keywords to their corresponding medical terminology using the National Library of Medicine's Consumer Health Vocabulary. We then developed a retrieval system called Search engine for Laypeople to access the COVID-19 literature (SLAC) using open-source software. Utilizing Centers for Disease Control and Prevention's FAQ questions as the basis for developing common questions that laypeople could be interested in, we performed a set of experiments for testing the SLAC system and the translation and expansion (T&E) process. Our experiment results demonstrate that the T&E process indeed helped to overcome the term mismatch problem and mapped laypeople terms to the medical terms in the academic articles. But we also found that not all laypeople's search topics are meaningful to search on the CORD-19 collection. This indicates the scope and the limitation of enabling laypeople to search on academic article collection for obtaining high-quality information.

      How to facilitate users to quickly and accurately search for the text information they need is a current research hotspot. Text clustering can improve the efficiency of information search and is an effective text retrieval method. Keyword extraction and cluster center point selection are key issues in text clustering research. Common keyword extraction algorithms can be divided into three categories: semantic-based algorithms, machine learning-based algorithms, and statistical model-based algorithms. There are three common methods for selecting cluster centers: randomly selecting the initial cluster center point, manually specifying the cluster center point, and selecting the cluster center point according to the similarity between the points to be clustered. The randomly selected initial cluster center points may contain "outliers," and the clustering results are locally optimal. Manually specifying the cluster center points will be very subjective because each person's understanding of the text set is different, and it is not suitable for the case of a large number of text sets. Selecting the cluster center points according to the similarity between the points to be clustered can make the selected cluster center points distributed in each class and be as close as possible to the class center points, but it takes a long time to calculate the cluster centers. Aiming at this problem, this paper proposes a keyword extraction algorithm based on cluster analysis. The results show that the algorithm does not rely on background knowledge bases, dictionaries, etc., and obtains statistical parameters and builds models through training. Experiments show that the keyword extraction algorithm has high accuracy and can quickly extract the subject content of an English translation.

      This study is based on Jumana Antoun's PhD thesis at Walden University, USA examining the information retrieval behaviour of 72 community family physicians' at the point of care in eight Arab countries in the Eastern Mediterranean. The key findings were that participants looked for digital clinical information at the point of care on average 14.0 times per week with the majority (80.3%) using a mobile phone. Clinical information about medication dosage and side effects was the most sought clinical question, and patient education was the least. Almost half of the participants considered that they often found relevant (55.6%), useful (56.9%) and unbiased (58.3%) information. Whilst none of the factors examined predicted the physicians' self-reported effectiveness and efficiency at information retrieval, the implication for practice points clearly to the barriers and the need for curricula to focus on search strategies using free resources at the point of care.

      BACKGROUND: Caregivers of children may rely on internet sources, health care providers, peers or family for health information.OBJECTIVE: To examine the impact of sociodemographic factors on the use of the internet for health information by caregivers of children, and the impact on self-efficacy, effort and frustration.
    METHODS: Using data from the 2019 Health Information National Trends Survey, the effects of information source on self-efficacy, effort and frustration was examined using the complex samples module of SPSS.
    RESULTS: The internet was the most common source of health information for caregivers of children (n = 247), with high confidence, low frustration and effort reported. Younger, higher educated and higher income caregivers were significantly more likely to use the internet for health information. Information from Health Care Providers (HCPs) was associated with greater confidence, and information from peers associated with lesser effort and frustration. No significant effects on self-efficacy, effort or frustration for online health information was noted compared to other sources.
    CONCLUSIONS: Efforts to reduce barriers to online health information may be required for some groups of caregivers, and health care providers may have a role to play in this.

      The current work asked how preschool-age children (N = 200) weigh accuracy against partisanship when seeking information. When choosing between a story that favored the ingroup but came from an unreliable source and a story that favored the outgroup but came from a reliable source, children were split between the two; although they tracked both reliability and bias, they were conflicted about which one to prioritize. Furthermore, children changed their opinions of the groups after hearing the story they had chosen; children who heard an unreliable ingroup-favoring story ended up more biased against the outgroup even while recognizing that the story's author was not a trustworthy source of information. Implications for the study of susceptibility to misinformation are discussed.

      BACKGROUND: The use of the internet for research is essential in the practice of evidence-based medicine. The online search habits of medical practitioners in clinical settings, particularly from direct observation, have received little attention.OBJECTIVE: The goal of the research is to explore online searching for information as an evidence-based practice among medical practitioners.
    METHODS: A cross-sectional study was conducted to evaluate the clinical teams' use of evidence-based practice when making clinical decisions for their patients' care. Data were collected through online searches from 2015 to 2018. Participants were medical practitioners and medical students in a Malaysian public teaching hospital's neonatal intensive care unit who performed online searches to find answers to clinical questions that arose during ward rounds.
    RESULTS: In search sessions conducted by the participants, 311 queries were observed from 2015 to 2018. Most participants (34/47, 72%) were house officers and medical students. Most of the searches were conducted by house officers (51/99, 52%) and medical students (32/99, 32%). Most searches (70/99, 71%) were directed rather than self-initiated, and 90% (89/99) were completed individually rather than collaboratively. Participants entered an average of 4 terms in each query; three-quarters of the queries yielded relevant evidence, with two-thirds yielding more than one relevant source of evidence.
    CONCLUSIONS: Our findings suggest that junior doctors and medical students need more training in evidence-based medicine skills such as clinical question formulation and online search techniques for performing independent online searches effectively. However, because the findings were based on intermittent opportunistic observations in a specific clinical setting, they may not be generalizable.

       Background: The relationship between search terms and suicidal ideation is not precisely known. Aims: This study examined the relationship between the types of terms used in web searches and the level of suicidal ideation among individuals who conduct such searches. Methods: A total of 508 Internet users completed a suicidal ideation scale and conveyed to us the words they used when searching for a consultation site. The site was run by the authors using Internet advertisement listings, to consult people via e-mail who had searched for suicide-related words. We divided the users into three groups based on the most salient search terms: suicide method terms, suicide but no method terms, and other terms. Results: The scores on the suicide ideation scale were compared using one-factor analysis of variance, and differences were found between the groups. Users searching for suicide method-related terms had the strongest suicidal ideation. Limitations: This study was limited to users who contacted online consultation sites because of their help-seeking intentions. Conclusion: It is especially important for support organizations to identify Internet users who directly search for suicide methods.

      STATEMENT OF PROBLEM: Complete arch fixed implant-supported prostheses have gained substantial popularity as a treatment option for patients with edentulism or a failing dentition. While YouTube is a leading source of health-related information videos, the usefulness and quality of videos on YouTube about complete arch fixed implant-supported prostheses are unclear.PURPOSE: The purpose of this study was to evaluate the quality of videos on complete arch fixed implant-supported prostheses and assess their usefulness for the general population as an educational resource.
    MATERIAL AND METHODS: An electronic search for "complete arch fixed treatment using dental implants" was conducted on YouTube on October 10, 2021. The videos in English with a duration between 4 and 20 minutes were considered for the analysis. A total of 89 videos were subjected to quantitative analysis by using a usefulness score. Additionally, to evaluate video quality, 5-point global quality scale (GQS) criteria were applied. A 1-way analysis of variance (ANOVA) was used to compare mean scores among different subgroups. The Pearson correlation analysis investigated the relationship among the usefulness score, GQS score, and video demographics, which include video content, source, type (academic or nonacademic), total views, and upload days (the days since the video was uploaded to YouTube) (α=.05).
    RESULTS: The mean number of views for the 89 selected videos was 193 321 with a mean daily upload of 1241. The mean ±standard deviation usefulness score was 1.55 ±1.35, with 78.7% of the videos rated poor, 20.2% moderate, and 1.1% excellent. The majority of videos included procedures involved (44.9%) and advantages (41.9%), and the least discussed topics were contraindications (7.9%) and prognosis and survival (6.7%). The GQS scoring had a mean score of 1.98 ±0.78 out of a total score of 5. While statistically significant differences were not found among the video source, total views or upload days, and usefulness score (P>.05), significant differences were found between the type of videos and usefulness score (P<.001).
    CONCLUSIONS: The majority of videos on complete arch fixed implant-supported rehabilitation were rated as poor in usefulness for patient education. Quality videos on implant-supported fixed rehabilitation were lacking on YouTube (GQS score <1.50), with most videos consisting of marketing or promotional content rather than unbiased educational information.

      OBJECTIVES: With the expansion of the internet, social media platforms have become a major source of medical information. However, medical information on online multimedia platforms is often inaccurate. In the current study, we evaluated the reliability, quality, and accuracy of the most viewed YouTube videos featuring the effects of vitamin C on COVID-19.METHODS: A search was conducted on YouTube on January 13, 2022, using the keywords ("ascorbic acid" OR "vitamin C" OR "sodium ascorbate" OR "L-ascorbic") AND ("coronavirus" OR "COVID 19" OR "COVID-19" OR "Corona" OR "COVID" OR "SARSCoV2"). We assessed the 50 most-viewed videos using a modified DISCERN scale (mDISCERN) and Global Quality Scale (GQS). Additionally, the accuracy of the information in each video was evaluated.
    RESULTS: Out of the 50 most-viewed videos featuring the effect of vitamin C on COVID-19, 54% were not reliable. Furthermore, 62% presented poor quality, and 74% were misleading or neither accurate nor misleading. The average mDISCERN and GQS scores of the 50 included videos were 2.2 ± 1.4 (≥ 3: highly reliable) and 2.2 ± 1.1 (2: generally poor), respectively. Although the videos were made by medical doctors, their reliability, quality, and accuracy were not significantly different from those displayed in other sources, including fitness channels, television or internet-based news or programs, consumers, company channels, product advertisements, or prepared by nurses.
    CONCLUSIONS: The reliability, quality, and accuracy of the 50 most-viewed videos on the effect of vitamin C on COVID-19 were not high. Video creators, especially medical doctors, should make an effort so that the videos present reliable content with high-quality and correct information is disseminated to people.

      INTRODUCTION: Physiotherapists and students may be vulnerable to false information and may learn faulty treatment techniques due to inadequate educational quality and uncertainty about sources and trustworthiness of YouTube videos.OBJECTIVE: To investigate educational quality, trustworthiness, and content completeness of joint mobilization techniques demonstrating videos available on YouTube.
    DESIGN: This is a descriptive study.
    METHODS: We performed a YouTube search on 1st April 2019, using the keyword 'Maitland joint mobilization technique for shoulder joint'. Three academic physiotherapists independently rated each video for educational quality, trustworthiness, and content completeness using the Global Quality Score, Journal of American Medical Association (JAMA) Benchmark Criteria and joint mobilization content completeness scale, respectively.
    RESULTS: Fifteen videos were included in the study. The median number of views for videos was 1263 (IQR 578-1478), and the median duration was 140 seconds (IQR 71-301 seconds). Most videos had low content quality (87%), poor joint mobilization content completeness (80%), and limited trustworthiness. All videos had low source quality (100%).
    CONCLUSIONS: There is a lack of quality information on shoulder joint mobilization techniques on YouTube, which makes it a limited educational tool for physiotherapists and students.

      Aim The aim of this study is to investigate the quality and reliability of YouTube videos containing content related to ovarian cysts. Methods The search terms "Ovarian Cyst", "Ovarian Cyst Symptoms", "Ovarian Cyst Treatment", and "Ovarian Cyst Diagnosis" were searched on YouTube. A total of 110 videos were examined and repetitive videos, non-English videos, videos with advertising content, videos with entertainment and news content, and videos with very poor image and sound quality were excluded. Finally, the videos included in the study were evaluated using DISCERN and Global Quality Scale (GQS). Results It was found that 50 videos examined in this study were uploaded between the years 2014 and 2020, with an average of 492.252 ± 710.768 and a total of 24.612.595 views. The mean DISCERN score given to 50 videos analyzed by two researchers was 2.81 ± 1.3 and the mean GQS score was 2.88 ± 1.4. When we divided the scores given to the videos by two researchers into three groups, it was determined that 27 (54%) of the 50 videos were in the misleading/poor quality group, nine (18%) were in the medium quality group, and 14 (28%) were in the useful/quality group. Conclusion It has been determined that the videos with "ovarian cyst" content on YouTube are generally of poor quality. Bad quality videos were uploaded by non-doctors and attracted more attention than videos uploaded by doctors.

      Purpose In this study, it was aimed to determine the quality and accuracy of the videos on YouTube about lateral epicondylitis. Methods The first 100 videos were included in the study by typing the keyword "lateral epicondylitis" in the YouTube search tab without using any filters. The video power index (VPI) was used to evaluate the popularity of the videos, and the global quality score (GQS), Journal of the American Medical Association (JAMA), and DISCERN scoring systems were used to evaluate the quality. The obtained data were statistically analyzed according to these scoring systems. Results The mean DISCERN, JAMA, and GQS of the analyzed videos were 46.66, 3.13, and 3.85, respectively. According to these results, it was determined that the videos were of medium quality. A statistically insignificant and weak correlation was found between the VPI and DISCERN, GQS, and JAMA scores (p>0.05, intraclass correlation coefficient, ICC: -0.05, 0.09, and -0.05, respectively). While there was no significant relationship between the video source and the DISCERN, JAMA, and GQS scores (p>0.05), it was determined that the DISCERN, JAMA, and GQS scores in the exercise videos were significantly higher than in the other content types in terms of the video content (p=0.041). Conclusions According to the results obtained, it was determined that YouTube videos about lateral epicondylitis were not of sufficient quality. In order to ensure standardization for quality videos, internationally acceptable guidelines should be determined and studies should be carried out to provide an adequate infrastructure for the preparation of quality medical videos that can meet the increasing needs of patients by health institutions.

      BACKGROUND: People with gestational diabetes have enhanced learning requirements during pregnancy, and management of their disease often requires the translation of health information into new health behavior changes. Seeking information from the internet to augment learning from health professionals is becoming more common during pregnancy. YouTube is a popular free and accessible web-based resource, which may be particularly useful for individuals with low health literacy or other barriers to receiving high-quality health care; however, the quality and content of YouTube videos varies, and little is known about those covering gestational diabetes.OBJECTIVE: We aimed to systematically evaluate the quality, content, and reliability of YouTube videos about gestational diabetes.
    METHODS: A systematic search of YouTube videos was conducted over the course of 1 week in April 2020 using the following keywords: "gestational diabetes," "gestational diabetes management," "gestational diabetes treatment," and "pregnancy and diabetes." The search results were displayed by relevance, replicating a default YouTube search attempt. The first 60 results from each keyword were reviewed (n=240). Exclusion criteria were videos unrelated to gestational diabetes, videos not in English, and those for which the full video was not available at the time of review. For each unique video, a gestational diabetes content score was used to rate video comprehensiveness and accuracy, and the DISCERN instrument, a validated metric to assess consumer health information, was used to evaluate the reliability of information presented. Videos were further categorized by quality: videos with DISCERN scores lower than 3 (out of 5) or a content score less than 4 (out of 7) were categorized as low quality, and all others were designated high quality. We performed descriptive analysis and compared video characteristics by source and quality rating.
    RESULTS: For 115 unique videos, the mean content score (out of 7) was 3.5 (SD 2.0) , and the mean DISCERN score (out of 5) was 2.7 (SD 0.7), representing low to moderate information comprehensiveness and reliability respectively. Video sources were categorized as personal vlog (12/115, 10.4%), web-based education (37/115, 32.2%), medical (52/115, 45.2%), business or company (13/115, 11.3%), and media clip (1/115, 0.9%). DISCERN and content scores trended higher among medical and web-based education videos. The majority of videos (n=88) were categorized as low quality, while 27 videos were categorized as high quality. Video duration was longer for high-quality videos (P<.001); high- and low-quality videos otherwise had similar views and viewer interaction numbers.
    CONCLUSIONS: Although high-quality videos about gestational diabetes exist, reliability, accuracy, and comprehensiveness were low overall, and higher quality was not associated with increased viewer interaction. It is important to acknowledge the limitations of this platform and to assist patients in accessing high quality content and differentiating the quality of information sources.

      OBJECTIVES: The use of video recording is commonplace in rhinology given the increased use of endoscopes when evaluating patients in the office and the operating room and for its educational potential. This study aimed to determine the quality of publicly available endoscopic videos in rhinology.METHODS: A video search was performed on YouTube in April of 2020 and included all videos since its inception in 2005 using terms related to rhinology found in the ACGME Case Log Coding Guide. Videos which met inclusion criteria were evaluated for video metrics and quality using validated scoring systems: Video Power Index (VPI), modified Journal of American Medical Association (JAMA) benchmark criteria, modified global quality score (GQS), and modified DISCERN criteria.
    RESULTS: A total of 138 videos were evaluated, 114 of which were uploaded independently, and 24 videos were uploaded by an academic institution. Academic-affiliated videos have higher like ratio at 91.7 ± 7.55% compared to 86.27 ± 17.44% (p = 0.018). Academic-affiliated videos have higher JAMA benchmark scores, DISCERN criteria scores, and GQS values [1.71 ± 0.55 versus 1.66 ± 0.49 (p = 0.66)], [ 3.33 ± 0.56 versus 2.85 ±0.65 (p <0.001)], [4.38 ± 0.81 versus 3.43 ± 1.01 (p <0.001)], respectively. There was no significant difference in VPI (p = 0.73).
    CONCLUSIONS: Endoscopic videos are rapidly growing in prominence and remain an important part of surgical education, but overall are heterogeneous in quality and reliability, necessitating an effort to establish both video sharing regulations and objective standards of quality.

      Introduction Dry eye disease (DED) is a common ocular pathology with significant impacts on both quality of life and visual function. One platform where individuals are receiving healthcare information is TikTok, the world's fastest-growing social media platform. Though used by more than one billion users, current literature is not established to assess the quality of information on TikTok. The purpose of this study was to assess the quality of DED-related medical information present on TikTok. Methods We conducted a cross-sectional analysis of DED content on TikTok, utilizing the search term #DryEye to assess the top 150 videos appearing on December 20, 2021. Included videos were analyzed for descriptive statistics, including views, likes, uploader profession, and the number of uploader followers. Videos were assessed utilizing DISCERN, a tool used to appraise consumer health information. The one-way analysis of variance (ANOVA) was used to determine statistical significance groups. Results A total of 101 videos were included in the final analysis. When comparing content creators, physicians received a significantly greater number of views and higher DISCERN scores (p<0.05) than non-physician medical providers and non-medical individuals. The content of the videos were educational content (n=39, 38.6%) or treatment information (n=37, 36.6%), followed by home remedies (n=10, 9.9%) and personal anecdotes (n=8, 7.9%). Videos with rich supplementary visuals (multiple images/moving images) had higher DISCERN scores compared to videos with no supplementary visuals or one supplementary visual (p<0.01). Conclusion With the growing popularity of TikTok, it is important to provide high-quality information to ensure the dissemination of medically accurate information and reduce the prevalence of disinformation. Our results demonstrate that while TikTok is a powerful platform, the quality of videos can still be vastly improved. Content creators, regardless of profession, can improve their DISCERN through listing sources, comparing treatments, and discussing risks/outcomes of various treatment modalities.
