    Finding citations for PubMed: a large-scale comparison between five freely available bibliographic data sources.
    Zhentao Liang, Jin Mao, Kun Lu, Gang Li.
      As an important biomedical database, PubMed provides users with free access to abstracts of its documents. However, citations between these documents need to be collected from external data sources. Although previous studies have investigated the coverage of various data sources, the quality of citations is underexplored. In response, this study compares the coverage and citation quality of five freely available data sources on 30 million PubMed documents, including OpenCitations Index of CrossRef open DOI-to-DOI citations (COCI), Dimensions, Microsoft Academic Graph (MAG), National Institutes of Health's Open Citation Collection (NIH-OCC), and Semantic Scholar Open Research Corpus (S2ORC). Three gold standards and five metrics are introduced to evaluate the correctness and completeness of citations. Our results indicate that Dimensions is the most comprehensive data source that provides references for 62.4% of PubMed documents, outperforming the official NIH-OCC dataset (56.7%). Over 90% of citation links in other data sources can also be found in Dimensions. The coverage of MAG, COCI, and S2ORC is 59.6%, 34.7%, and 23.5%, respectively. Regarding the citation quality, Dimensions and NIH-OCC achieve the best overall results. Almost all data sources have a precision higher than 90%, but their recall is much lower. All databases have better performances on recent publications than earlier ones. Meanwhile, the gaps between different data sources have diminished for the documents published in recent years. This study provides evidence for researchers to choose suitable PubMed citation sources, which is also helpful for evaluating the citation quality of free bibliographic databases.

    The roles of the US National Library of Medicine and Donald A.B. Lindberg in revolutionizing biomedical and health informatics.
    Randolph A Miller, Edward H Shortliffe.
      Over a 31-year span as Director of the US National Library of Medicine (NLM), Donald A.B. Lindberg, MD, and his extraordinary NLM colleagues fundamentally changed the field of biomedical and health informatics-with a resulting impact on biomedicine that is much broader than its influence on any single subfield. This article provides substance to bolster that claim. The review is based in part on the informatics section of a new book, "Transforming biomedical informatics and health information access: Don Lindberg and the US National Library of Medicine" (IOS Press, forthcoming 2021). After providing insights into selected aspects of the book's informatics-related contents, the authors discuss the broader context in which Dr. Lindberg and the NLM accomplished their transformative work.

    Philanthropy in Public Libraries: Its Impact on Community Well-Being Missions.
    Kathryn Dilworth.
      Public libraries support community well-being missions related to access to information, knowledge creation, public service programming and social cohesion. Interviews in this study were designed to discover whether philanthropy in the form of giving positively impact their ability to deliver these missions. Four public library directors in Mississippi were selected for this study because the state reports low community well-being measures and high charitable giving. Findings suggest that philanthropy is a fundamental partner in community well-being missions for these libraries even though, as a sector, public libraries measure low in philanthropic support.

    An alternative screening approach for Google Search identifies an accurate and manageable number of results for a systematic review (case study).
    Simon Briscoe, Morwenna Rogers.
       BACKGROUND: A challenge when using Google Search to identify studies for a systematic review is managing the high number of results, which can number in the hundreds of thousands or even more. Studies and guidance on web searching suggest limiting the screening process, e.g. to the first 100 results.
    OBJECTIVES: Our objective in this case study is to demonstrate an alternative approach to screening the results retrieved by Google Search which is based on our experience that the viewable number of results is often far fewer than the estimated number calculated by the search engine.
    METHODS: We screened the results of three searches of Google Search using our approach, which involves increasing the number of results displayed per page from 10 to the maximum of 100. We then calculated the viewable number of results and compared this with the estimated number.
    RESULTS: The mean of the estimated number of results for the three searches was 569,454,000. The mean of the viewable number results was 463 (0.00008% of the mean of the estimated number of results).
    CONCLUSION: Our findings challenge the commonly reported view that the number of results retrieved when using Google Search is too high to screen in full.

    Knowledge, Information Sources, and Institutional Trust of Patients Regarding Medication Use in Pregnancy: A Systematic Review.
    Abirami Kirubarajan, Andrew Lam, Amy Yu, Cameron Taheri, Shawn Khan, Claire Sethuram, Vikita Mehta, Nancy Olivieri.
      Objective: The objective of our study is to characterize the knowledge, information sources, and institutional trust of patients regarding medication use in pregnancy. Materials and methods: We conducted a review of three databases: MEDLINE, EMBASE, and CINAHL. We included observational studies and knowledge assessments that examined the knowledge, attitudes, beliefs or information sources of pregnant patients related to medication use during pregnancy. Extraction was completed by two independent reviewers, outcomes were summarized descriptively, and appraisal was conducted. Results: Of the 1359 search results, 34 studies met inclusion criteria. Thus, our systematic review encompasses the beliefs of 11,757 pregnant participants. In most studies, participants described apprehension regarding potential risks to the fetus and the inadequacy of safety information. Across the 23 knowledge assessments, the majority of studies reported patient misconceptions about prescription medication in pregnancy. The most preferred information source was a healthcare provider. However, many participants expressed frustration, mistrust, and skepticism regarding physician knowledge. A common source of mistrust was due to perceived physician self-interest as well as a lack of education tailored to pregnancy. Consequently, informal sources of information were also popular. Conclusion: There is a need to improve the health literacy and trust among pregnant patients regarding drug prescribing. There are modifiable risk factors for mistrust that require further attention.

    Information sourcing by dog owners in the UK: Resource selection and perceptions of knowledge.
    Christina Ann Kuhl, Rachel Dean, Caroline Quarmby, Richard Graham Lea.
       BACKGROUND: Dogs are a popular pet in the UK. Information resources utilised by dog owners can influence welfare at acquisition and throughout a dog's lifetime. This study determined where UK dog owners source information, and how perceptions relating to pedigree dog breeding and health may influence this process.
    METHODS: This cross-sectional study used online questionnaires to explore the information resources used by dog owners and their perceptions of veterinary surgeons' and dog breeders' knowledge.
    RESULTS: Overall, 1336 responses were collected (useable responses: 1167). Data indicated most owners conducted research before getting a dog, with the internet, books, breeders and friends or family among the most popular resources used. Preferred sources of information during a dogs' lifetime included the internet, talking to veterinary surgeons and reading books. Veterinary surgeons were the most popular source for health advice. Pedigree dog owners perceived veterinary surgeons and breeders to be equally knowledgeable on canine inherited diseases. However, veterinary surgeons were perceived as being more knowledgeable on inherited disease screening programmes and breeders more knowledgeable on dog breeding.
    CONCLUSION: This study highlights the information resources preferred by dog owners, providing an opportunity to maximise access to reliable sources of information to improve dog welfare.

    Assessing the Accuracy, Quality, and Readability of Information Related to the Surgical Management of Benign Prostatic Hyperplasia.
    David Bouhadana, David-Dan Nguyen, Brendan Raizenne, Sai K Vangala, Iman Sadri, Bilal Chughtai, Dean Elterman, Kevin Christopher Zorn, Naeem Bhojani.
       OBJECTIVES: To assess the accuracy, quality, and readability of online educational health information in English related to the most common benign prostatic hyperplasia (BPH) guideline-approved surgical treatments.
    METHODS: The terms "benign prostatic hyperplasia", "BPH", and all eight guideline-approved treatment modalities studied, were searched to retrieve the first five relevant websites and first two paid advertised websites related to the surgical treatment options for BPH. These modalities included transurethral resection of the prostate (TURP), GreenLight photovaporization, endoscopic enucleation of the prostate, Rezum, Urolift, Aquablation, open simple prostatectomy (OSP), and robotic simple prostatectomy (RSP). All relevant websites were assessed for their accuracy, quality, and readability using standardized scoring systems.
    RESULTS: The mean accuracy score for each of the treatment modalities were all indicative of good accuracy, with 76-99% of the information presented as being accurate. The median quality score was statistically different across the 8 treatment modalities (P=.015). The median readability grade level was statistically different across the 8 treatment modalities (P=.009). Websites that described TURP (median readability grade level, 9.00 [IQR,8.00-10.80]) were significantly easier to read than those related to RSP (median readability grade level, 14.35 [IQR,11.08-16.50]) (P= 0.011). No other statistically significant differences were found within the other treatment modality websites.
    CONCLUSIONS: The majority of websites retrieved were found to be of high accuracy, good quality, and poor readability. Additionally, it was found that none of the retrieved websites included descriptions for all of the other included treatment modalities. Given these findings, the authors recommend the development of centralized resources with all guideline-approved treatment modalities and accurate, readable, and high-quality information related to the surgical treatment of BPH.

    Readability of Online Patient Material Provided by Reflux Centers in the United States.
    Elisabeth Ekkel, Kevin Seeras.
      The American Medical Association (AMA) and the National Institutes of Health (NIH) suggest patient education materials should not exceed the sixth-grade reading level. Several studies have shown that patient information has been written well above this reading level across multiple specialties. A search was conducted utilizing the Google Chrome browser and the Google search engine. The key words "Reflux Center" and "GERD Center" were used to identify links to programs within the United States. The web site's general description of reflux or gastroesophageal reflux disease was copied and pasted into the Readable.io service, and the readability tests were conducted via the program. Of 52 web sites, none had fulfilled the recommended reading level. Our results reveal that readability related to reflux pathology on center web sites is too difficult for the average patient. In order to improve patient education regarding reflux pathology and treatment, reading materials should be improved.

    Dupuytren's Contracture: The Readability of Online Information.
    Shayan Hosseinzadeh, Philip Blazar, Brandon E Earp, Dafang Zhang.
      Dupuytren's contracture is a common hand pathology for which consultation and treatment are largely at the patient's discretion. The objective of this study was to evaluate the readability of current online patient information regarding Dupuytren's contracture. The largest public search engines (Google, Yahoo, and Bing) were queried using the search terms "Dupuytren's contracture," "Dupuytren's disease," "Viking's disease," and "bent finger." The first 30 unique websites by each search were analyzed and readability assessed using five established algorithms: Flesch Reading Ease, Gunning-Fog Index, Flesch-Kincaid Grade level, Coleman-Liau index, and Simple Measure of Gobbledygook grade level. Analysis of 73 websites demonstrated an average Flesch Reading Ease score of 48.6 ± 8.0, which corresponds to college reading level. The readability of websites ranged from 10.5 to 13.3 reading grade level. No article was written at or below the recommended sixth grade reading level. Information on the internet on Dupuytren's contracture is written at higher than recommended reading grade level. There is a need for high-quality patient information on Dupuytren's contracture at appropriate reading grade levels for patients of various health literacy backgrounds. Hospitals, universities, and academic organizations focused on the development of readable online information should consider patients' input and preferences.

    YouTube as a Source of Information on Blenderised Tube Feeding.
    Anna Walsh, Omowunmi Bamkole, Konstantinos Gerasimidis.
       ABSTRACT: Blenderised tube feeding (BTF) has become an increasingly popular method of nutrition support to long-term tube-fed patients mostly children. This study surveyed perceptions and experiences on BTF shared on YouTube. From 71 videos analysed, attitudes toward BTF were mostly positive (91%) and included psychosocial benefits and improvements in gastrointestinal symptoms; no differences between caregivers and healthcare professionals were observed. Very few speakers (8%) felt there was a lack of support regarding use of BTF in schools and from healthcare professionals, since it is not part of the standard clinical management protocols. The most commonly used food items in blends included carrots (n=16) and chicken (n=11), and experiences from those who have used BTF included tips on recipes for blends, storing feeds and ensuring nutritional adequacy. Analysis of YouTube content on BTF was considerably positive and suggests that BTF is feasible and safe way to provide nutrition to tube fed patients.

    Examination of Health Information Needs of Caregivers of and Individuals with Burn Injuries.
    Tammie M Jones, Alaanah Bhanji, Gheeta Ahuja, Ramez Bakhtar, Xinsheng Cindy Cai, Steven Garfinkel, Lynn Gerber, Ali A Weinstein.
      Burns are a leading cause of trauma worldwide with about 450,000 burn injuries being treated at medical facilities in the United States each year. Finding relevant information on the long-term consequences of burn injuries is a significant challenge for many individuals with burn injuries and their caregivers. This qualitative study aimed to identify how individuals with burn injuries and caregivers of individuals with burn injuries prefer to access and use health information, identify obstacles to accessing useful information, and identify information most needed by burn survivors and caregivers. Participants were recruited through hospital listservs, websites, social media, and word of mouth from across the United States. Semi-structured interviews were conducted with twenty-three individuals, 12 with burn injuries and 11 caregivers of individuals with burn injuries. Three specific needs were identified: (1) more direction from health professionals in finding health information relevant to burn injuries; (2) more internet-based access points that connect individuals to appropriate support networks; and (3) more support for long-term consequences of burn injuries, specifically with psychological, social, and other chronic physical issues. Participants identified various needs in finding relevant health information, thereby highlighting gaps in current literature and the dissemination of current literature. One potential way to address these deficiencies is to consider user-centered design principles in developing research, by more directly involving individuals with burn injuries and caregivers as part of the research team.

    Pattern of internet use for pregnancy-related information and its predictors among women visiting primary healthcare in Qatar: a cross-sectional study.
    Ayman Al-Dahshan, Mohamad Chehab, Ayatullah Mohamed, Noora Al-Kubaisi, Nagah Selim.
       BACKGROUND: Internet usage has been steadily increasing and the available online information for pregnant women today is immense.
    OBJECTIVE: This study aimed to investigate the prevalence of women who search for information relating to pregnancy on the internet and to identify predictors of this behavior among expecting women visiting primary health care (PHC) centers in Qatar.
    METHODS: A cross-sectional study was conducted at the antenatal clinics of six PHC centers in Qatar from June 1 to December 31, 2019. Pregnant women were recruited through a systematic random sampling technique. Participants were interviewed using a structured questionnaire. Descriptive and analytic statistics were used when appropriate. A multivariable logistic regression analysis was constructed to identify the predictors of internet use for pregnancy-related information.
    RESULTS: The study included 403 pregnant women (response rate: 87.9%). Most of them were in the 26-35 years age category (71.5%), in the second trimester (55.5%), and had 1-2 children at home (51.5%). The internet was the most common source (81.1%) of pregnancy-related information. The access to online information was mainly through websites (67.3%), mobile applications (48.3%), and social media platforms (39.7%). The most frequently searched topics online were fetal development (74.3%), diet during pregnancy (53.6%), and management of health problems (39.6%). The multivariable regression model identified the age group 26-35 years (AOR: 4.93; 95% CI: 2.14, 11.38), Arabs (AOR: 4.12; 95% CI: 2.03, 8.36), tertiary education (AOR: 5.22; 95% CI: 1.78, 15.33), being a housewife (AOR: 6.37; 95% CI: 1.44, 28.19), or employed (AOR: 5.56 95% CI: 1.31, 23.63), and having up to 2 children as independent predictors of internet use for pregnancy-related information.
    CONCLUSION: The internet was a commonly used source of health information among pregnant women in Qatar. Internet use was significantly associated with the age group of 26-35 years, Arabs, higher level of education, being employed or a housewife, and having up to two children.

    Information seeking and health anxiety during the COVID-19 pandemic: The mediating role of catastrophic cognitions.
    Shreya Jagtap, Amanda L Shamblaw, Rachel Rumas, Michael W Best.
      Cognitive-behavioural models of health anxiety propose a positive association between information seeking and health anxiety, however, it is unclear the extent to which cognitive mechanisms may mediate this relationship. Catastrophic cognitions are one type of cognition that may mediate this relationship and the COVID-19 pandemic has presented an opportunity to examine these relationships within the context of a global health catastrophe. The current study investigated both cross-sectional (N = 797) and longitudinal (n = 395) relationships between information seeking, health anxiety, and catastrophizing during the pandemic. Data were collected using Amazon Mechanical Turk during April and May 2020. Information seeking and health anxiety were positively associated both cross-sectionally and longitudinally (rs = .25 - .29). Catastrophic cognitions significantly mediated the relationship between information-seeking and health anxiety both cross-sectionally and longitudinally. Developing effective methods of reducing information-seeking and catastrophizing may serve to reduce health anxiety during global health crises such as the current pandemic.

    The Use of Internet and Social Media for Health Information and Its Consequences Among the Population in Saudi Arabia.
    Sarah A AlMuammar, Afnan S Noorsaeed, Raghad A Alafif, Yumna F Kamal, Ghaida M Daghistani.
       BACKGROUND: The Internet is being increasingly used in our lives. Along with Internet use, social media sites are especially popular and are used by many people on a daily basis. Many studies were conducted to see the people's perception and their attitude towards the use of the Internet for health information. Such studies were also carried out in Saudi Arabia, but most have been limited to a specific target sample of the population. Our study aimed to assess the perception towards and use of different platforms and search engines to seek health information in Saudi Arabia.
    METHOD: A cross-sectional study was conducted in Saudi Arabia during the year 2021. An Arabic online questionnaire using Google forms was sent to a randomized sample. Microsoft Excel 2016 was used for data entry, and statistical analysis was performed using IBM© SPSS© Statistics version 25 (IBM© Corp., Armonk, NY, USA).
    RESULT: Among the 1363 participants, 56.2% were females and 43.8% were males with a mean age of 30.73 ± 12.3. The majority were living in Western region. The most used social media platforms were WhatsApp (91.5%), YouTube (84.6%), and Twitter (82.6%), respectively. The most common medical websites browsed were the Saudi Ministry of Health (67%) and the Food and Drug Administration (54.4%). Some 40.1% of the participants had a medical consultation online from a doctor, and most of them (67.8%) trusted the online physician. Finally, most of the participants (90.9%) thought that health information on the Internet or social media contributes to raising the level of health awareness among the general population. There was a significant relationship between educational level and gender and online health-seeking behavior (p > 0.05).
    CONCLUSION: The study reinforced that health information that is sought from the Internet and social media platforms has a great impact on the population, emphasizing the need for credible information sources and how to access them.

    Patterns of Google search behavior for epilepsy and seizures in the Philippines: An infodemiological study.
    Kevin Michael C Moalong, Roland Dominic G Jamora, Katrina T Roberto, Adrian I Espiritu.
       BACKGROUND: The internet has been established as a rich source of health information that is well utilized by the public. Online health information-seeking behavior may reflect public awareness in particular health-related topics, including epilepsy and seizures.
    OBJECTIVE: This study aimed to describe online search behavior for epilepsy and seizures in the Philippines through the examination of trends of Philippine-based Google search queries for epilepsy and seizure-related terms.
    METHODS: The search volume indices (SVIs) for the keywords "epilepsy (disorder)" and "seizure (disease)" based on Philippine-based Google searches from January 2004 to July 2021 were generated using Google Trends. Descriptive analysis of search volume patterns, including related topics and queries, was performed.
    RESULTS: There was a recent relative increase in Philippine-based searches related to the term "seizure" with a concurrent relative decline in searches related to the term "epilepsy" over time. The Philippines had the fifth-highest SVI for "seizure" based on worldwide trends. Most searches centered on the definition, symptomatology, etiologies, classification, and treatment of seizures and epilepsy. Queries containing seizure-related terms rose in volume by more than 5000% during the seventeen-year period. Search volume tended to peak during the National Epilepsy Awareness Week in September but slumped during holiday months.
    CONCLUSIONS: Online search behavior in the Philippines for seizure-related terms appears to be on the rise and may reflect increasing public awareness in epilepsy. Factors including fears surrounding epileptic seizures, the stigma surrounding the term "epilepsy", and seasonal events including a regularly held epilepsy awareness week may influence online search behavior.

    Software review: The JATSdecoder package-extract metadata, abstract and sectioned text from NISO-JATS coded XML documents; Insights to PubMed central's open access database.
    Ingmar Böschen.
      JATSdecoder is a general toolbox which facilitates text extraction and analytical tasks on NISO-JATS coded XML documents. Its function JATSdecoder() outputs metadata, the abstract, the sectioned text and reference list as easy selectable elements. One of the biggest repositories for open access full texts covering biology and the medical and health sciences is PubMed Central (PMC), with more than 3.2 million files. This report provides an overview of the PMC document collection processed with JATSdecoder(). The development of extracted tags is displayed for the full corpus over time and in greater detail for some meta tags. Possibilities and limitations for text miners working with scientific literature are outlined. The NISO-JATS-tags are used quite consistently nowadays and allow a reliable extraction of metadata and text elements. International collaborations are more present than ever. There are obvious errors in the date stamps of some documents. Only about half of all articles from 2020 contain at least one author listed with an author identification code. Since many authors share the same name, the identification of person-related content is problematic, especially for authors with Asian names. JATSdecoder() reliably extracts key metadata and text elements from NISO-JATS coded XML files. When combined with the rich, publicly available content within PMCs database, new monitoring and text mining approaches can be carried out easily. Any selection of article subsets should be carefully performed with in- and exclusion criteria on several NISO-JATS tags, as both the subject and keyword tags are used quite inconsistently.
