      BACKGROUND: Health information-seeking behavior (HISB) plays a key role in self-care management, promoting quality of life and improving health. However, some individual and contextual barriers hinder women undergoing mastectomy access to needed information. Identifying and removing health information-seeking barriers for these women undergoing mastectomy can lead to improving their health outcomes. Therefore, the aim of this study was to identify the health information-seeking barriers for women with breast cancer after mastectomy.MATERIALS AND METHODS: This was a conventional qualitative content analysis in which the participants were selected through purposive sampling based on the study inclusion criteria from two hospitals of Shahid Mohammadi and Persian Gulf and Chemotherapy Center of Omid in Bandar Abbas. The study population consisted of 17 women with breast cancer after mastectomy. Data were collected through semi-structured face-to-face interviews.
    RESULTS: Seven main themes were introduced as three individual barriers, including fear, shame and embarrassment and inadequate health literacy and four contextual barriers of economic status, physicians and medical staff, lack of accessibility of information sources and the behavior of those around them that were the underlying factors to explain the barriers of health information seeking in mastectomized women.
    CONCLUSION: The results of this study emphasize the need for further attention from Iranian authorities to health care, especially women' health care institutions, to reform the health system and remove their health information -seeking barriers.<br />.

      STUDY DESIGN: An internet-based survey.OBJECTIVES: To determine how individuals with spinal cord injury (SCI) access information about experimental therapies and clinical trials. To understand which factors influence receipt of and perceived trustworthiness of that information.
    SETTING: Two academic medical centers and an SCI organization.
    METHODS: Demographic information frequencies and percentages were calculated then analyzed using chi-square tests for independence. Fisher's exact test of independence was used to assess significance for contingency tables with categories containing expected counts below five.
    RESULTS: Three hundred sixty four persons with SCI participated in the survey. Most felt confident in their ability to evaluate SCI-specific information from a variety of sources, though SCI organizations and the medical literature were deemed the most reliable. Information from SCI specialists was deemed more credible than that from non-SCI specialists, but only 53.6% of participants had access to them. Nearly all (89.0%) respondents who had sought information about experimental therapies had found it online, while 51.4% of those who had participated in a clinical trial had been contacted by a research team. Only 8.4% of participants felt their medical teams offered them sufficient information about experimental therapies and clinical trials. Wealthier and more educated respondents were more knowledgeable about health-related resources on the internet. Nearly all participants (96.9%) expressed interest in learning more about trials related to SCI.
    CONCLUSIONS: There is an information deficit among people with SCI pertaining to experimental therapies and clinical trials. It is exacerbated by lack of income, education, and access to SCI specialists.

      PURPOSE: Oropharyngeal cancer is estimated to continue to increase in the next decades. Prevention strategies and knowing the current situation of knowledge and concern of the population about this disease is necessary. Infodemiology is valuable to monitor health information-seeking behaviour trends and epidemiology. The objective of this study is to analyze the use and evolution, through Google trends as a source of information, of internet-based information-seeking behaviour related to the oropharyngeal cancer in Spain and related to mass media stories.METHODS: Using Google Trends, the terms "throat cancer', "HPV", "laryngeal cancer", "tonsil cancer" and "oral cancer". The searches volume and trend were analyzed using a Jointpoint regression method from January 2009 to July 2019.
    RESULTS: The most searched term was "HPV", with a search volume index of 61, followed by "throat cancer" (SVI = 25). The trend of the term "HPV" increased 6.1% annually (p < 0.000), with a linear correlation of both terms of 0.52 (p < 0.000). The greatest number of searches was carried out in the north of Spain, the most repeated query being "oral sex AND cancer". A correlation between the news in the media and the increase in the volume of searches for the terms was found.
    CONCLUSION: Any news stories, new interventions or aetiology related to oropharyngeal cancer can manifest as an increase in information-seeking behaviours for "throat cancer" on Google. Understanding healthcare information-seeking behaviour is essential in order to control and plan the quality of knowledge provided by health organisations, advocacy groups and health professionals regarding head and neck cancers.

      A website and a Facebook page were launched in Malta in March 2020 to disseminate accurate and up-to-date general information and the latest scientific developments vis-à-vis the COVID-19 pandemic. The website provides brief, accurate and pertinent information on COVID-19 and serves to dispel misconceptions. The aim of this small research was to obtain feedback from website users on the presentation and layout of the website, to ascertain the level of awareness of the website and to obtain information on improvement for future use. An anonymous survey was created using Google forms. The survey asked questions about design, presentation, information presented and suggestions for improvement and was open between 22nd May and 31st May. It was shared online through the Facebook page COVID-19: As it happens. There were 51 responses to the questionnaire. The results established the importance of a clean and simple design and presentation. They also outlined the importance of social media in delivering the desired message and confirm that the website is a trusted and reliable source of information. On a local level, COVID-19: As it happens website disseminates trustworthy information both on a local and international level. The major challenge to the scientific and medical communities in the new COVID-19 reality is that so many people have more access and opportunity to create content, including material that is misleading or false. In this context, COVID-19: As it happens has been created to provide accessible evidence-based research for the lay public.

      BACKGROUND: Biomedical named entity recognition (BioNER) is an important task for understanding biomedical texts, which can be challenging due to the lack of large-scale labeled training data and domain knowledge. To address the challenge, in addition to using powerful encoders (e.g., biLSTM and BioBERT), one possible method is to leverage extra knowledge that is easy to obtain. Previous studies have shown that auto-processed syntactic information can be a useful resource to improve model performance, but their approaches are limited to directly concatenating the embeddings of syntactic information to the input word embeddings. Therefore, such syntactic information is leveraged in an inflexible way, where inaccurate one may hurt model performance.RESULTS: In this paper, we propose BIOKMNER, a BioNER model for biomedical texts with key-value memory networks (KVMN) to incorporate auto-processed syntactic information. We evaluate BIOKMNER on six English biomedical datasets, where our method with KVMN outperforms the strong baseline method, namely, BioBERT, from the previous study on all datasets. Specifically, the F1 scores of our best performing model are 85.29% on BC2GM, 77.83% on JNLPBA, 94.22% on BC5CDR-chemical, 90.08% on NCBI-disease, 89.24% on LINNAEUS, and 76.33% on Species-800, where state-of-the-art performance is obtained on four of them (i.e., BC2GM, BC5CDR-chemical, NCBI-disease, and Species-800).
    CONCLUSION: The experimental results on six English benchmark datasets demonstrate that auto-processed syntactic information can be a useful resource for BioNER and our method with KVMN can appropriately leverage such information to improve model performance.

      Neuroimaging text mining extracts knowledge from neuroimaging texts and has received widespread attention. Topic learning is an important research focus of neuroimaging text mining. However, current neuroimaging topic learning researches mainly used traditional probability topic models to extract topics from literature and cannot obtain high-quality neuroimaging topics. The existing topic learning methods also cannot meet the requirements of topic learning oriented to full-text neuroimaging literature. In this paper, three types of neuroimaging research topic events are defined to describe the process and result of neuroimaging researches. An event based topic learning pipeline, called neuroimaging Event-BTM, is proposed to realize topic learning from full-text neuroimaging literature. The experimental results on the PLoS One data set show that the accuracy and completeness of the proposed method are significantly better than the existing main topic learning methods.

      OBJECTIVE: To investigate the applicability of supervised machine learning (SML) to classify health-related webpages as 'reliable' or 'unreliable' in an automated way.METHODS: We collected the textual content of 468 different Dutch webpages about early childhood vaccination. Webpages were manually coded as 'reliable' or 'unreliable' based on their alignment with evidence-based vaccination guidelines. Four SML models were trained on part of the data, whereas the remaining data was used for model testing.
    RESULTS: All models appeared to be successful in the automated identification of unreliable (F1 scores: 0.54-0.86) and reliable information (F1 scores: 0.82-0.91). Typical words for unreliable information are 'dr', 'immune system', and 'vaccine damage', whereas 'measles', 'child', and 'immunization rate', were frequent in reliable information. Our best performing model was also successful in terms of out-of-sample prediction, tested on a dataset about HPV vaccination.
    CONCLUSION: Automated classification of online content in terms of reliability, using basic classifiers, performs well and is particularly useful to identify reliable information.
    PRACTICE IMPLICATIONS: The classifiers can be used as a starting point to develop more complex classifiers, but also warning tools which can help people evaluate the content they encounter online.

      BACKGROUND/OBJECTIVES: An increasing number of patients are using the internet to supplement information provided by medical professionals. Online geriatric patient education materials (PEMs) should be written at or below a 6th grade reading level (GRL) that takes into account barriers unique to the geriatric population. The objectives of the study are to assess PEMs of geriatric associations' websites and determine whether they are above the GRL recommended by the Centers for Disease Control and National Institutes of Health.DESIGN: Descriptive and correlational methodology. PEMs from 10 major geriatric associations were assessed for their GRL using 10 scales. Eight of the scales provide a numerical GRL while two of the scales provide a visual representation of the GRLs. Analysis was conducted using Readability Studio 2019.3.
    SETTING: Analysis was conducted February 2020.
    PARTICIPANTS: Identified 10 geriatric associations and 884 PEMs.
    MEASUREMENTS: GRLs were measured by 10 validated readability indices: the Degrees of Reading Power and Grade Equivalent test, Flesch-Kincaid grade level, Simple Measure of Gobbledygook test, Coleman-Liau Index, Gunning Fog Index, New Fog Count, New Dale-Chall readability formula, Ford, Caylor, Sticht scale, Raygor readability estimate graph, and Fry readability graph.
    RESULTS: The mean of all PEMs using the numerical scales was 11.1 ± 2.4. Ninety-nine percent of PEMs are above the 6th GRL. PEMs ranged from a grade 3.0 to 19.0 reading level. Analysis of variance demonstrated a significant difference between associations (P < .0001), and multiple comparison analysis identified the National Institute on Aging as the content easiest to read (9.5 ± 1.6).
    CONCLUSION: PEMs from geriatric association websites are written above the recommended 6th GRL. As patients increasingly look toward online supplementary health information during COVID-19, there is an opportunity for improving PEMs to enable greater comprehension by the target population.

      BACKGROUND:  Increasingly, people access Internet-based health information about various chronic conditions including hearing loss and hearing aids. YouTube is one media source that has gained much popularity in recent years.PURPOSE:  The current study examines the source, content, understandability, and actionability of YouTube videos related to hearing aids.
    RESEARCH DESIGN:  Cross-sectional design by analyzing the videos at single point in time.
    STUDY SAMPLE:  One hundred most frequently viewed videos in YouTube.
    INTERVENTION:  Not applicable.
    DATA COLLECTION AND ANALYSIS:  The 100 most-viewed English language videos targeting individuals seeking information regarding hearing aids were identified and manually coded. Data collection included general information about the video (e.g., source, title, authorship, date of upload, duration of video), popularity-driven measures (e.g., number of views, likes, dislikes), and the video source (consumer, professional, or media). The video content was analyzed to examine what pertinent information they contained in relation to a predetermined fact sheet. Understandability and actionability of the videos were examined using the Patient Education Material Assessment Tool for Audiovisual Materials.
    RESULTS:  Of the 100 most-viewed videos, 11 were consumer-based, 80 were created by professionals, and the remaining 9 were media-based. General information about hearing aids, hearing aid types, and handling and maintenance of hearing aids were the most frequently discussed content categories with over 50% of all videos commenting on these areas. Differences were noted between source types in several content categories. The overall understandability scores for videos from all sources were 74%, which was considered adequate; however, the actionability scores for all the videos were 68%, which is considered inadequate.
    CONCLUSION:  YouTube videos about hearing aids focused on a range of issues and some differences were found between source types. The poor actionability of these videos may result in incongruous consumer actions. Content and quality of the information in hearing aid YouTube videos needs to be improved with input from professionals.

      OBJECTIVE: To assess the readability of pet obesity information, document the presence and absence of types of pet obesity information, and perform comparisons between dog and cat obesity information content on websites.SAMPLE: 68 websites containing pet obesity content.
    PROCEDURES: Websites were systematically retrieved with a search engine and predefined search terms and phrases. For each website, pet obesity information was scored by use of 2 established readability tools: the simple measure of gobbledygook (SMOG) index and Flesch-Kincaid (FK) readability test. A directed content analysis was conducted with a codebook that assessed the presence or absence of 103 variables across 5 main topics related to pet obesity on each website.
    RESULTS: The mean reading grade levels determined with the SMOG index and FK readability test were 16.61 and 9.07, respectively. Instructions for weight measurement and body condition scoring were found infrequently, as were nonmodifiable risk factors. There was a greater focus on addressing obesity through dietary changes than through increasing physical activity. Few websites recommended regular follow-up appointments with veterinarians. Weight management information and the emphasis on owners' commitment to achieve their pet's weight loss targets differed among dog- and cat-focused websites.
    CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that pet obesity information on the studied websites was largely inaccessible to pet owners owing to the associated high reading grade levels. Readers of that information would benefit from clarification of information gaps along with provision of guidance regarding navigating online information and counseling on the importance of nutritional and dietary reassessments for individual pets performed by veterinarians.
