The Reliability of YouTube as an Information Resource for Parents About Retinopathy of Prematurity.

To investigate the quality and reliability of YouTube videos about retinopathy of prematurity (ROP) to direct parents of infants with the disease to access more accurate content. The term "retinopathy of prematurity" has been searched on YouTube containing all of the videos between January 2 and February 2, 2024. The first 200 videos were evaluated by two ophthalmologists. Duplicated-split videos, videos shorter than 60 seconds, videos presented in languages other than English or with an incomprehensible accent, and videos unrelated to ROP were excluded. Video uploaders, types, continental origins, durations, and viewer interactions were noted. DISCERN, The Journal of the American Medical Association (JAMA), and the Global Quality Score (GQS) scoring systems were used to evaluate the quality of the videos. The mean quality of all videos was poor in all scoring systems. Academic societies and medical institutes scored highest in video uploaders, followed by physicians; patient experience videos had the lowest quality. Of the video types, the medical education seminars were of the highest quality. Although a strong positive correlation was detected between video duration and video quality, this same strong correlation was not observed between viewer interactions and video quality. There was no significant difference between video origins in terms of video quality. It would be wiser to direct the parents of patients with ROP to watch longer videos uploaded by the academic community, medical institute, or physicians, and to watch the medical training seminars. Also, it might be important to warn them not to take user interactions too seriously. [J Pediatr Ophthalmol Strabismus. 20XX;XX(X):XXX-XXX.].

Perception and Effectiveness of Online Anatomy Lab Exercise on Undergraduate Students of BPKIHS During COVID-19 Pandemic

Introduction: Online mode of teaching learning activities were started for medical students of Nepal to reduce the risk of spreading virus during COVID-19 pandemic. BPKIHS started the modified online lab exercise (LABEX) for the undergraduate students after six months of pandemic. Objective: The main objective of study was to evaluate the student’s perception and effectiveness of modified online LABEX (prior content video uploading) during pandemic. Methods: The mixed method cross-sectional study design using semi-structured questionnaire was conducted. The questionnaire had sub-sections such as questions regarding students’ means of study, students’ perception on modified online lab exercise during pandemic and reflective writing. We collected the responses from 129 students after institutional ethical clearance and informed consent. Student’s paired test for analysis of effectiveness of modified online LABEX was done by using pre-test/post-test score. Thematic analysis was performed for reflective writing. A p<0.05 was considered as statistically significant. Results: The mean age was calculated as 20.84 year. The modified online LABEX increase the scoring of students for three consecutive sessions with an average score of 1.71; 1.55 & 1.09 respectively (p<0.001). We formulated 15 codes and 3 themes from reflective writing such as strength, weakness and recommendation of modified online LABEX. We found that “Accessibility of recorded Labex” (n=54) was major strength and “less efficient of online LABEX” (n=57) was major weakness. Conclusions: Although physical form of anatomy education is best way of learning but modified online LABEX can be used as alternative during pandemic like situations in future

Extremely compact video representation for efficient near-duplicates detection

With the influx of online video uploads, a robust method for detecting video copies under various distortions is essential for copyright protection and search efficiency. We propose a compact video representation that uses a Siamese Neural Network for near-duplicate detection. This approach achieves up to 0.998 recall and 0.853 precision, even with distorted 56x56px miniatures. Consequently, we derive extremely compact video descriptors, facilitating video fragment retrieval in large datasets. Our method pre-selects frames from a video by identifying local maximums from the interframe differences curve, preserving characteristic sequence patterns even after extreme compression. Utilizing a simpler convolution-based model in the Siamese Neural Network, we improve results by up to 8% over VGG-16, with a 1.7-fold reduction in inference time. With compact descriptors of 1.875 kB, our models outperform others by more than two times. Additionally, we introduce a new dataset with dynamically changing scenes, enhancing its suitability for near-duplicate video detection.

Douyin and Bilibili as sources of information on lung cancer in China through assessment and analysis of the content and quality

Lung cancer has emerged as a major global public health concern. With growing public interest in lung cancer, online searches for related information have surged. However, a comprehensive evaluation of the credibility, quality, and value of lung cancer-related videos on digital media platforms remains unexamined. This study aimed to assess the informational quality and content of lung cancer-related videos on Douyin and Bilibili. A total of 200 lung cancer-related videos that met the criteria were selected from Douyin and Bilibili for evaluation and analysis. The first step involved recording and analyzing the basic information provided in the videos. Subsequently, the source and type of content for each video were identified. All videos’ educational content and quality were then evaluated using JAMA, GQS, and Modified DISCERN. Douyin videos were found to be more popular in terms of likes, comments, favorites, and shares, whereas Bilibili videos were longer in duration (P < .001). The majority of video content on both platforms comprised lung cancer introductions (31/100, 31%), with medical professionals being the primary source of uploaded videos (Douyin, n = 55, 55%; Bilibili, n = 43, 43%). General users on Douyin scored the lowest on the JAMA scale, whereas for-profit businesses scored the highest (2.50 points). The results indicated that the videos’ informational quality was insufficient. Videos from science communications and health professionals were deemed more reliable regarding completeness and content quality compared to videos from other sources. The public should exercise caution and consider the scientific validity when seeking healthcare information on short video platforms.

How Useful Is TikTok for Patients Searching for Carpal Tunnel Syndrome-Related Treatment Exercises?

Since orthopedic surgery has been slower to acknowledge the rise of social media for distributing medical information, this study aims to evaluate TikTok videos' quality and educational value in relation to carpal tunnel syndrome treatment exercises. TikTok was searched using the hashtags "#carpaltunnelexercises", "#carpaltunnelremedies", "#carpaltunnelrehab", and "#physicaltherapyforcarpaltunnel". The engagement indicators were documented and the video content quality was assessed using the DISCERN, CTEES, JAMA, and GQS grading scales. There were 101 videos included, which accumulated 20,985,730 views. The videos received 1,460,953 likes, 15,723 comments, 243,245 favorites, and 159,923 shares. Healthcare professionals were responsible for 72% of the video uploads, whereas general users contributed 28%. More healthcare professionals' videos were graded as "poor" (79%) compared to general users (21%). General users received slightly more video grades of "very poor" (52%) than healthcare professionals (48%). For the DISCERN grading, the videos by healthcare professionals were significantly better than those by general users in terms of reliability, achieving aims, and relevancy. They were also superior in the overall composition of the health information derived from the total DISCERN score. However, no significant differences were found between the two groups when using the CTEES, JAMA, and GQS grading scales. Overall, despite the emergence of TikTok as a medical information tool, the quality and educational value of the carpal tunnel syndrome exercise videos were poor.

Is YouTube a Useful Source of Information on Pressure Injuries? A Content, Reliability, and Quality Analysis.

To evaluate the comprehensiveness, reliability, and quality of YouTube videos related to pressure injuries. The authors searched YouTube for relevant videos using the keywords "pressure injury", "pressure ulcer", "bedsore", "pressure injury etiology", "pressure injury classification", "pressure injury prevention", "pressure injury risk assessment", and "pressure injury management". Of the 1,023 videos screened, 269 met the inclusion criteria and were included in the study. For each video, the authors recorded the number of views, likes, and comments; the length; and the video upload source. The Comprehensiveness Assessment Tool for Pressure Injuries, the Quality Criteria for Consumer Health Information score, and the Global Quality Score were used to evaluate the comprehensiveness, reliability, and quality of the videos. The mean length of the 269 videos was 6.22 ± 4.62 minutes (range, 0.18-19.47 minutes). Only 14.5% of the videos (n = 39) were uploaded by universities or professional organizations. Most videos included information about PI prevention (69.5%), followed by PI management (27.9%). The mean comprehensiveness score was 2.33 ± 1.32 (range, 1-5). Nearly half of the videos (49.1%) were not reliable. However, the quality of 43.9% of the videos was somewhat useful. The Quality Criteria for Consumer Health Information mean scores of universities/professional organizations (P < .001), nonprofit healthcare professionals (P = .015), and independent health information channel videos (P = .026) were higher than the mean score of medical advertising/profit companies channel videos. This study draws attention to the need for more comprehensive, high-quality, and reliable videos about PIs. It is important that videos on YouTube provide comprehensive and reliable information for patients, caregivers, students, or providers seeking information on PI prevention, assessment, and management.

YouTube/ Bilibili/ TikTok videos as sources of medical information on laryngeal carcinoma: cross-sectional content analysis study

BackgroundYouTube, a widely recognized global video platform, is inaccessible in China, whereas Bilibili and TikTok are popular platforms for long and short videos, respectively. There are many videos related to laryngeal carcinoma on these platforms. This study aims to identify upload sources, contents, and feature information of these videos on YouTube, Bilibili, and TikTok, and further evaluate the video quality.MethodsOn January 1, 2024, we searched the top 100 videos by default sort order (300 videos in total) with the terms “laryngeal carcinoma” and “throat cancer” on YouTube, “喉癌” on Bilibili and TikTok. Videos were screened for relevance and similarity. Video characteristics were documented, and quality was assessed by using the Patient Education Materials Assessment Tool (PEMAT), Video Information and Quality Index (VIQI), Global Quality Score (GQS), and modified DISCERN (mDISCERN).ResultsThe analysis included 99 YouTube videos, 76 from Bilibili, and 73 from TikTok. Median video lengths were 193 s (YouTube), 136 s (Bilibili), and 42 s (TikTok). TikTok videos demonstrated higher audience interaction. Bilibili had the lowest ratio of original contents (69.7%). Treatment was the most popular topic on YouTube and Bilibili, while that was the prognosis on TikTok. Solo narration was the most common video style across all platforms. Video uploaders were predominantly non-profit organizations (YouTube), self-media (Bilibili), and doctors (TikTok), with TikTok authors having the highest certification rate (83.3%). Video quality, assessed using PEMAT, VIQI, GQS, and mDISCERN, varied across platforms, with YouTube generally showing the highest scores. Videos from professional authors performed better than videos from non-professionals based on the GQS and mDISCERN scores. Spearman correlation analysis showed no strong relationships between the video quality and the audience interaction.ConclusionsVideos on social media platforms can help the public learn about the knowledge of laryngeal cancer to some extent. TikTok achieves the best flow, but videos on YouTube are of the best quality. However, the video quality across all platforms still needs enhancement. We need more professional uploaders to ameliorate the video quality related to laryngeal carcinoma. Content creators also should be aware of the certification, the originality, and the style of video shooting. As for the platforms, refining the algorithm will allow users to receive more high-quality videos.

THE ROLE OF LANGUAGE IN SHAPING TEACHERS’ IDENTITY ON TIKTOK

TikTok application is one of the most used applications recently. From 14 years old until 30 years old people spend more than 30 minutes a day opening this application. Enormous, interesting videos with varied topics make many people like TikTok. Besides that, they can create their video easily with the features which are already provided. This phenomenon affects education as well. Teachers try to utilize this application as their learning media. Not only that, but teachers also create their accounts and upload videos that are related to the learning process or education. Therefore, the researcher is interested to know how the language used by teachers in TikTok shapes their identity. The researcher analyzed two subjects, two of them teachers in different countries. This research used a qualitative method that describes the language used in three videos in teachers’ TikTok accounts and analyses it. The findings revealed that both teachers wanted to be seen as capable and friendly teachers because they know how to build an interesting learning process and build good relationships with their students.

The introduction of video-enabled directly observed therapy (video-DOT) for patients with drug-resistant TB disease in Eswatini amid the COVID-19 pandemic – a retrospective cohort study

BackgroundVideo-enabled directly observed therapy (video-DOT) has been proposed as an additional option for treatment provision besides in-person DOT for patients with drug-resistant TB (DRTB) disease. However, evidence and implementation experience mainly originate from well-resourced contexts. This study describes the operationalization of video-DOT in a low-resourced setting in Eswatini facing a high burden of HIV and TB amid the emergence of the COVID-19 pandemic.MethodsThis is a retrospectively established cohort of patients receiving DRTB treatment during the implementation of video-DOT in Shiselweni from May 2020 to March 2022. We described intervention uptake (vs. in-person DOT) and assessed unfavorable DRTB treatment outcome (death, loss to care) using Kaplan-Meier statistics and multivariable Cox-regression models. Video-related statistics were described with frequencies and medians. We calculated the fraction of expected doses observed (FEDO) under video-DOT and assessed associations with missed video uploads using multivariable Poisson regression analysis.ResultsOf 71 DRTB patients eligible for video-DOT, the median age was 39 (IQR 30–54) years, 31.0% (n = 22) were women, 67.1% (n = 47/70) were HIV-positive, and 42.3% (n = 30) were already receiving DRTB treatment when video-DOT became available. About half of the patients (n = 37; 52.1%) chose video-DOT, mostly during the time when COVID-19 appeared in Eswatini. Video-DOT initiations were lower in new DRTB patients (aHR 0.24, 95% CI 0.12–0.48) and those aged ≥ 60 years (aHR 0.27, 95% CI 0.08–0.89). Overall, 20,634 videos were uploaded with a median number of 553 (IQR 309–748) videos per patient and a median FEDO of 92% (IQR 84–97%). Patients aged ≥ 60 years were less likely to miss video uploads (aIRR 0.07, 95% CI 0.01–0.51). The cumulative Kaplan-Meier estimate of an unfavorable treatment outcome among all patients was 0.08 (95% CI 0.03–0.19), with no differences detected by DOT approach and other baseline factors in multivariable analysis.ConclusionsImplementing video-DOT for monitoring of DRTB care provision amid the intersection of the HIV and COVID-19 pandemics seemed feasible. Digital health technologies provide additional options for patients to choose their preferred way to support treatment taking, thus possibly increasing patient-centered health care while sustaining favorable treatment outcomes.

Evaluation Of Youtube Videos About Teething

Aim: Parents increasingly turn to platforms like YouTube to find information about their infants' health. While health professionals are the primary source of such information, the accessibility of medical content on the internet and the demand for remote healthcare services during the COVID-19 pandemic have made medical YouTube videos popular. In the field of pediatric dentistry, YouTube offers valuable insights into topics like oral hygiene, early childhood caries, and fluoride use. This study aimed to assess the content and quality of YouTube videos on teething symptoms in infants, identified as a highly searched topic on Google Trends. Methods: Content analysis, DISCERN reliability scoring, and five-point Global Quality Scale (GQS) assessment were conducted on a sample of 46 videos. Results were categorized by uploader gender, video source category, and video quality. Statistical analyses, including Kruskal-Wallis and Mann-Whitney U tests, along with correlation analysis, were performed to identify differences between videos and groups. Results: Among the video uploaders, 80.60% (n=38) were female, and 17.40% (n=8) were male. No statistically significant difference based on gender was found among video uploaders (p&gt;0.05). Most videos were uploaded by non-healthcare professionals, health institutions, workers, and other YouTube channels. Mean view counts, likes, dislikes, and comments were determined for the examined videos. The quality of videos was evaluated using Global Quality Scale and DISCERN ratings, resulting in categorization as weak, moderate, and high quality based on Global Quality Scale scores. Conclusion: This study revealed varying quality in YouTube videos on teething symptoms in infants, with non-healthcare professionals' videos demonstrating lower quality. Nonetheless, reliable videos from pediatric dental experts can serve as valuable resources for parents with limited access to healthcare facilities, particularly during situations like the pandemic. Further research and support are needed in this area.

Assessment of the Quality and Reliability of Content Available on YouTube About Palpitations.

Palpitations refer to the sensation of rapid, fluttering, or pounding heartbeats in the chest, the determinants of which may range from hormonal changes to anxiety or arrhythmias. YouTube is one of the most prevailing and accepted web-based platforms people trust to help them understand more about their health conditions. Thus, this study aims to assess whether the quality of content about palpitations on this platform is reliable and sufficient. Seventy-one YouTube videos were analyzed using criteria such as date and time of upload, type of uploader, and type of content. The Global Quality Score (GQS) and modified DISCERN score were used to analyze the quality and reliability of the information provided. Microsoft Excel (Microsoft Corporation, Redmond, WA, US) was used for data analysis, and StataCorp's 2023 Stata Statistical Software (College Station, TX, US) was used for statistical analysis and visualization. Of the 71 videos analyzed, 90.14% were uploaded more than a year ago, 80.28% described the symptomatology in detail, and 81.69% accurately described the etiological factors. Hospitals and doctors were the most common uploaders, constituting 23% and 19% of the uploaded videos, respectively, and had high GQSs (Median GQS = 4). The highest scores also belonged to videos uploaded by patients suffering from the disease (Median GQS = 5). Hospitals and news channels ranked highest on the reliability score (Median DISCERN = 4, respectively). It was determined that despite varied sources, the nature of content provided by the platform contains promotional material and content gaps; YouTube should, therefore, be used critically and as per professional sources.

A two-actor model for understanding user engagement with content creators: Applying social capital theory

The emergence of video sharing platforms has given rise to the creation and consumption of tourism-related content. However, there is limited knowledge about the characteristics of content creators that enhance users' engagement with their content. The present study aims to fill this gap by examining creator characteristics and their impact on three tiers of user engagement. Tourism-related content, comprising 366 videos across six destinations, was extracted from YouTube using three social media analytic tools: VidIQ, TubeBuddy, and SocialBlade. The data were analyzed using PLS-SEM with SmartPLS 4.0. The findings reveal that channel subscribers positively influence user engagement at three levels – views, likes, and comments. However, a higher number of video uploads negatively impacts engagement. Furthermore, older videos tend to garner more views, but users' tendency to like the videos decreases over time. In addition, we extracted 23,993 comments and performed sentiment analysis on users’ comments using Python-based VADER social media sentiment analysis tool. The compound-based sentiment analysis reveals that 59.5 percent of users show positive sentiments toward tourism-related content on YouTube while only 9.3 comments were negative, and 31.2 percent of sentiments remain neutral. Temporal analysis shows the rising trend in qualitative user engagement from 2010 to 2023, highlighting a growing interest in consuming and interacting with tourism-related content. This study discusses its theoretical contributions and managerial implications for content creators, destination managers, and advertising agencies.

An analysis of YouTube content about psychobiotics: Is the food and mood bond getting stronger?

Aim: Psychobiotics have become a popular topic in recent years both on social media and in academia. The effects of individuals' diets and the probiotic supplements they use on their mental state have made psychobiotics a subject of curiosity. Our aim in this research is to evaluate the content of YouTube videos about psychobiotics. Materials and Methods: On 13/12/2023, the content of the first 50 english videos related to psychobiotics on YouTube was examined for quality and reliability and was independently evaluated by 2 separate medical professionals. Data such as likes, number of views, upload dates and uploaders of the videos were recorded. The content quality of the videos was recorded by calculating the DISCERN score and Global Quality Index score (GQS). Results: The mean duration of YouTube videos about psychobiotics was 14.35 minutes. The mean GQS and modified DISCERN scores of the videos were 3.70 and 3.87, respectively. The evaluation results of two independent medical professionals who watched the videos showed a high positive correlation in terms of both GQS and DISCERN scores (r: 0.905, r: 0.908). The duration, number of likes and daily view counts of professional videos were significantly higher (p :0.001). 62% of the videos were uploaded by health channels, 28% by healthcare professionals and 10% by other individuals. GQS (p:0.005) and DISCERN (p:0.007) scores of videos uploaded by health professionals and health channels were significantly higher than others. Conclusion: Since psychobiotics is known as a newly popular term among the public and in the academic field, it has been observed that YouTube videos in this field are relatively new, uploaded by more professional channels compared to other subjects, and have more satisfactory content than other fields in terms of quality and content. However, since the number of videos is low compared to more publicly known topics and it is a relatively new topic, it may be beneficial to increase the number and promotion of professional videos to increase society's knowledge about psychobiotics.

University students' self-presentation on Tiktok in the context of group communication

The phenomenon of self-presentation is increasingly trending to reveal, develop identities, manipulate and customise individuals' self-images on social media. University students present themselves on TikTok through video uploads, music, and distributed using TikTok's highly personalised algorithms in group communication: watch history, re-watches, likes, comments, and post-view activity. We present the concept of online impression management through the lens of self-presentation theory as the practice of conveying self-impression and controlling personal information to represent one's self-image to be liked. This study uses a qualitative approach, uses phenomenological methods to find the meaning and interpretation of self-presentation through uploads on TikTok. They expressed personal information to their reference group and experimented based on different roles when constructing identity. Some strategies are used to give a positive impression to their friends. They projected different versions of themselves depending on self-category and group communication context when receiving positive feedback or likes.

Evaluation of the quality and content of YouTube videos as an educational resource in developing patients’ inhaler use skills

Background YouTube has educational videos on inhalers. However, their content and quality are not adequately known. Objectives This study investigated the quality and content of educational YouTube videos on inhalers. Methods This descriptive study analyzed 178 YouTube videos on inhalers between May and July 2022. Two researchers independently evaluated the videos. The Global Quality Score (GQS), Journal of American Medical Association (JAMA) Benchmark Criteria, and Inhaler Application Checklist (IAC) were used to assess the quality and content of the videos. Spearman’s correlation, Kruskal–Wallis, Mann–Whitney U, ANOVA, and Post hoc analysis Bonferroni test were used for data analysis. Results The videos had a mean GQS score of 3.70 ± 1.24, and JAMA score of 2.22 ± 0.60. A negative correlation was between the quality score of the videos and views, likes, comments, duration, and likes/views (respectively; r = −0.237 p < 0.005, r = −0.217 p < 0.003, r = −0.220 p < 0.005, r = −0.147, p < 0.005). The videos narrated by nurses and doctors had significantly higher mean JAMA and GQS scores than others (p = 0.001). The videos missed some procedural steps [gargling (29.1%), adding no more than five ml of medication and device cleaning (41.9%), and exhaling through the nose (37.5%)]. Videos uploaded by individual missed significantly more procedural steps than professional organizations (p < 0.05). Conclusions YouTube videos about inhaler techniques have a moderate level of quality. Videos uploaded by doctors and nurses as content narrators were of higher quality. The videos missed some procedural steps. Individual video uploaders had higher missed procedural steps. Counseling should be provided to patients regarding the reliability of online information.

Fully Automatic Camera for Personalized Highlight Generation in Sporting Events.

Personally curated content in short-form video formats provides added value for participants and spectators but is often disregarded in lower-level events because it is too labor-intensive to create or is not recorded at all. Our smart sensor-driven tripod focuses on supplying a unified sensor and video solution to capture personalized highlights for participants in various sporting events with low computational and hardware costs. The relevant parts of the video for each participant are automatically determined by using the timestamps of his/her received sensor data. This is achieved through a customizable clipping mechanism that processes and optimizes both video and sensor data. The clipping mechanism is driven by sensing nearby signals of Adaptive Network Topology (ANT+) capable devices worn by the athletes that provide both locality information and identification. The device was deployed and tested in an amateur-level cycling race in which it provided clips with a detection rate of 92.9%. The associated sensor data were used to automatically extract peloton passages and report riders' positions on the course, as well as which participants were grouped together. Insights derived from sensor signals can be processed and published in real time, and an upload optimization scheme is proposed that can provide video clips for each rider a maximum of 5 min after the passage if video upload is enabled.
