RESUMO

G-quadruplexes (GQs) have been primarily studied in the context of cancer and neurodegenerative pathologies. However, recent research has shifted focus to their existence and functional roles in viral genomes, revealing GQ-regulated key pathways in various human pathogenic viruses. While GQ structures have been reported in the genomes of emerging and re-emerging viruses, RNA viruses have been understudied compared to DNA viruses, including notable examples such as human immunodeficiency virus-1, hepatitis C virus, Ebola virus, Nipah virus, Zika virus, and SARS-CoV-2. The flavivirus family, comprising the Japanese encephalitis virus (JEV), poses a significant global threat due to recurring outbreaks yet lacks approved antivirals. In this study, we identified and characterized eight putative G-quadruplex-forming motifs within essential genes involved in genome replication, assembly, and internalization in the host cell, conserved across different JEV isolates. The formation and stability of these motifs were validated through a multitude of biophysical and cell-based assays. The interaction and binding affinity of these motifs with the known GQ-binding ligand BRACO-19 were supported by biophysical assays, confirming the capability of these motifs to form GQ structures. Notably, BRACO-19 also exerted antiviral properties through reduction of viral replication and infectious virus titers as well as inhibition of viral protein expression, as evaluated by the cell-based assays. This comprehensive molecular characterization of G-quadruplex structures within the JEV genome highlights their potential as promising antiviral targets for intervention strategies against JEV infection through GQ-specific ligands.

RESUMO

BACKGROUND: In China, mitral valve regurgitation (MR) is the most common cardiovascular valve disease. However, patients in China typically experience a high incidence of this condition, coupled with a low level of health knowledge and a relatively low rate of surgical treatment. TikTok hosts a vast amount of content related to diseases and health knowledge, providing viewers with access to relevant information. However, there has been no investigation or evaluation of the quality of videos specifically addressing MR. OBJECTIVE: This study aims to assess the quality of videos about MR on TikTok in China. METHODS: A cross-sectional study was conducted on the Chinese version of TikTok on September 9, 2023. The top 100 videos on MR were included and evaluated using quantitative scoring tools such as the modified DISCERN (mDISCERN), the Journal of the American Medical Association (JAMA) benchmark criteria, the Global Quality Score (GQS), and the Patient Education Materials Assessment Tool for Audio-Visual Content (PEMAT-A/V). Correlation and stepwise regression analyses were performed to examine the relationships between video quality and various characteristics. RESULTS: We obtained 88 valid video files, of which most (n=81, 92%) were uploaded by certified physicians, primarily cardiac surgeons, and cardiologists. News agencies/organizations and physicians had higher GQS scores compared with individuals (news agencies/organizations vs individuals, P=.001; physicians vs individuals, P=.03). Additionally, news agencies/organizations had higher PEMAT understandability scores than individuals (P=.01). Videos focused on disease knowledge scored higher in GQS (P<.001), PEMAT understandability (P<.001), and PEMAT actionability (P<.001) compared with videos covering surgical cases. PEMAT actionability scores were higher for outpatient cases compared with surgical cases (P<.001). Additionally, videos focused on surgical techniques had lower PEMAT actionability scores than those about disease knowledge (P=.04). The strongest correlations observed were between thumbs up and comments (r=0.92, P<.001), thumbs up and favorites (r=0.89, P<.001), thumbs up and shares (r=0.87, P<.001), comments and favorites (r=0.81, P<.001), comments and shares (r=0.87, P<.001), and favorites and shares (r=0.83, P<.001). Stepwise regression analysis identified "length (P<.001)," "content (P<.001)," and "physicians (P=.004)" as significant predictors of GQS. The final model (model 3) explained 50.1% of the variance in GQSs. The predictive equation for GQS is as follows: GQS = 3.230 - 0.294 × content - 0.274 × physicians + 0.005 × length. This model was statistically significant (P=.004) and showed no issues with multicollinearity or autocorrelation. CONCLUSIONS: Our study reveals that while most MR-related videos on TikTok were uploaded by certified physicians, ensuring professional and scientific content, the overall quality scores were suboptimal. Despite the educational value of these videos, the guidance provided was often insufficient. The predictive equation for GQS developed from our analysis offers valuable insights but should be applied with caution beyond the study context. It suggests that creators should focus on improving both the content and presentation of their videos to enhance the quality of health information shared on social media.

RESUMO

PURPOSE: To evaluate the quality and reliability of YouTube videos as an educational resource about myopia. METHODS: The videos were identified by searching YouTube with the keywords 'myopia' and 'nearsightedness', using the website's default search settings. The number of views, likes, dislikes, view ratio, source of the upload, country of origin, video type, and described treatment techniques were assessed. Each video was evaluated using the DISCERN, Journal of the American Medical Association (JAMA), Ensuring Quality Information for Patients (EQIP), Health On the Net Code of Conduct Certification (HONcode), and the Global Quality Score (GQS) scales. RESULTS: A total of 112 videos were included. The classification of videos by source indicated that the top three contributors were health channels (30 videos [26.8%]), physicians (24 videos [21.4%]), and academic centers (19 videos [16.9%]). Most of these videos originated from the United States (74 videos [66.1%]) and focused on the pathophysiology (n = 89, 79.4%) and the treatment (n = 77, 68.7%) of myopia. Statistical comparisons among the groups of video sources showed no significant difference in the mean DISCERN score (p = 0.102). However, significant differences were noted in the JAMA (p = 0.011), GQS (p = 0.009), HONcode (p = 0.011), and EQIP (p = 0.002) scores. CONCLUSIONS: This study underscored the variability in the quality and reliability of YouTube videos related to myopia, with most content ranging from 'weak to moderate' quality based on the DISCERN and GQS scales, yet appearing to be 'excellent' according to the HONcode and EQIP scales. Videos uploaded by physicians generally exhibited higher standards, highlighting the importance of expert involvement in online health information dissemination. Given the potential risks of accessing incorrect medical data that can affect the decision-making processes of patients, caution should be exercised when using online content as a source of information.

RESUMO

PURPOSE: In the digital era, the internet is the go-to source of information, and patients often seek insights on medical conditions like TMJ ankylosis. YouTube, a popular platform, is widely used for this purpose. However, YouTube's lack of regulation means it can host unreliable content. Hence, the primary objective of this study is to assess the scientific quality of YouTube videos concerning TMJ ankylosis. MATERIALS AND METHODS: This study analyzed 59 TMJ ankylosis-related videos. Two Oral and Maxillofacial Surgery specialists assessed these videos. Data on the video source, duration, upload date, the time elapsed since upload, total views, likes, dislikes and comments, Interaction index, and viewing rate were collected and analyzed. Video quality was assessed using the Global Quality Scale (GQS) and the Quality Criteria for Consumer Health Information (DISCERN), comparing health professionals and non-health professionals. RESULTS: Health professional's videos were better in terms of GQS 3.21 ± 0.94 and DISCERN score 3.03 ± 0.75 as compared to the non-health professional videos GQS 3.0 ± 1.04, and DISCERN 2.81 ± 1.13. Health professional group videos had more reliability and better quality than the non-health professional group (p < 0.01). CONCLUSION: YouTube should not be relied on as a trustworthy source for high-quality and reliable information regarding TMJ ankylosis videos. Healthcare professionals must be prepared to address any ambiguous or misleading information and to prioritize building trustworthy relationships with patients through accurate diagnostic and therapeutic processes.

RESUMO

Background: Several pelvic area cancers exhibit high incidence rates, and their surgical treatment can result in adverse effects such as urinary and fecal incontinence, significantly impacting patients' quality of life. Post-surgery incontinence is a significant concern, with prevalence rates ranging from 25 to 45% for urinary incontinence and 9-68% for fecal incontinence. Cancer survivors are increasingly turning to YouTube as a platform to connect with others, yet caution is warranted as misinformation is prevalent. Objective: This study aims to evaluate the information quality in YouTube videos about post-surgical incontinence after pelvic area cancer surgery. Methods: A YouTube search for "Incontinence after cancer surgery" yielded 108 videos, which were subsequently analyzed. To evaluate these videos, several quality assessment tools were utilized, including DISCERN, GQS, JAMA, PEMAT, and MQ-VET. Statistical analyses, such as descriptive statistics and intercorrelation tests, were employed to assess various video attributes, including characteristics, popularity, educational value, quality, and reliability. Also, artificial intelligence techniques like PCA, t-SNE, and UMAP were used for data analysis. HeatMap and Hierarchical Clustering Dendrogram techniques validated the Machine Learning results. Results: The quality scales presented a high level of correlation one with each other (p < 0.01) and the Artificial Intelligence-based techniques presented clear clustering representations of the dataset samples, which were reinforced by the Heat Map and Hierarchical Clustering Dendrogram. Conclusions: YouTube videos on "Incontinence after Cancer Surgery" present a "High" quality across multiple scales. The use of AI tools, like PCA, t-SNE, and UMAP, is highlighted for clustering large health datasets, improving data visualization, pattern recognition, and complex healthcare analysis.

RESUMO

AIMS: This study aimed to evaluate and compare the reliability and quality of the information about gingival enlargements on YouTube and TikTok. METHODS: Two popular video sites, YouTube and TikTok, were searched for gingival enlargement and gingival hyperplasia. The reliability and quality of the first 300 videos for each search term, which is 1200 videos in total, were evaluated by social media video content evaluation tools: Global Quality Score (GQS) for quality and modified DISCERN for reliability. RESULTS: Health professionals uploaded 68.6% of the videos on YouTube and 54.5% on TikTok. It was observed that 50% of TikTok videos and 65.9% of YouTube videos were educational. In terms of quality, 2.7% of the videos on YouTube are of excellent quality, while in TikTok there are no videos of perfect quality. TikTok videos had considerably more views, likes, viewing rates, and interaction index scores than YouTube videos (P < 0.01). CONCLUSIONS: The videos and pieces of information on YouTube are more reliable and accurate in terms of gingival enlargement when compared to TikTok. Nevertheless, it was discovered that videos on both platforms were of poor reliability and quality in general.

RESUMO

BACKGROUND: Prostate and colorectum cancers rank among the most common cancers, and incontinence is a significant postsurgical issue affecting the physical and psychological well-being of cancer survivors. Social media, particularly YouTube, has emerged as a vital source of health information. While YouTube offers valuable content, users must exercise caution due to potential misinformation. OBJECTIVE: This study aims to assess the quality of publicly available YouTube videos related to incontinence after pelvic cancer surgery. METHODS: A search on YouTube related to "Incontinence after cancer surgery" was performed, and 108 videos were analyzed. Multiple quality assessment tools (DISCERN, GQS, JAMA, PEMAT, and MQ-VET) and statistical analyses (descriptive statistics and intercorrelation tests) were used to evaluate the characteristics and popularity, educational value, quality, and reliability of these videos, relying on novel graphical representation techniques such as Sankey and Chord diagrams. RESULTS: Strong positive correlations were found among quality rating scales, emphasizing agreement. The performed graphical analysis reinforced the reliability and validity of quality assessments. CONCLUSIONS: This study found strong correlations among five quality scales, suggesting their effectiveness in assessing health information quality. The evaluation of YouTube videos consistently revealed "high" quality content. Considering the source is mandatory when assessing quality, healthcare and academic institutions are reliable sources. Caution is advised with ad-containing videos. Future research should focus on policy improvements and tools to aid patients in finding high-quality health content.

RESUMO

STUDY OBJECTIVE: YouTube, the largest accessible media-sharing platform, has become an important tool for pursuing health-related information. Adolescents may find it challenging to seek counseling or access adolescent-friendly services for menstruation-related problems, so YouTube may be a useful resource. The aim of this study was to examine the reliability, quality, and accuracy of YouTube videos concerning abnormal uterine bleeding in adolescents. METHODS: A YouTube search using the key words "adolescent, teens, heavy period, abnormal uterine bleeding, heavy menstrual bleeding" yielded 109 videos. Video features (duration, time since upload, likes, views, comments), sources of upload, and content were recorded. All the videos were reviewed by 2 adolescent medicine specialists and scored using the Journal of the American Medical Association, the 5-point modified DISCERN tool, and the Global Quality Scale. RESULTS: Fifty-eight videos met the inclusion criteria. Most (62.1%) were created by non-professionals, and a significant portion (81%) contained general descriptions. On the basis of the DISCERN classification, 50% exhibited poor quality. Similarly, the Journal of the American Medical Association assessment indicated that only 36.2% satisfied the requirements for good quality. The videos uploaded by professionals exhibited notably superior quality in comparison with those uploaded by non-professionals. Additionally, higher-quality videos were longer (P = .040) and more recent (P = .011). CONCLUSION: Mot YouTube videos about adolescent abnormal uterine bleeding provide low-quality information. We believe that increasing the number of videos tailored by health care providers specializing in adolescent gynecology to address the specific physical and psychosocial needs of adolescents with menstrual problems would be beneficial.

RESUMO

Background and aims In the age of social media, a vast amount of information is widely and easily accessible. Platforms such as Instagram allow its users to post pictures and videos that can reach millions of users. This could be utilized by healthcare providers to provide education to a vast number of the population about a disease such as hypothyroidism with an easily digestible infographic. However, this easy accessibility comes with the risk of rampant misinformation. This study aimed to evaluate the characteristics of Instagram posts, the type of information, and the quality and reliability of information posted about hypothyroidism. Methodology This is a cross-sectional observational study that was conducted over the course of days on Instagram. Top posts meeting inclusion criteria under seven different hypothyroidism-related hashtags were surveyed for content and social media metrics by the authors utilizing Google Forms. The quality and reliability of the posts were analyzed using the global quality scale and DISCERN scales, respectively. The data were exported to an Excel sheet and analyzed using the SPSS software version 21.0 (Armonk, NY: IBM Corp.). Results A total of 629 posts met the inclusion criteria of which 62.5% were images and 37.5% were reels. The content heavily focused on the medical aspect of hypothyroidism with posts about symptoms (46.1%), prevention (39.59%), cause/etiology (36.41%), and treatment (34.34%). The median DISCERN score which reflects the reliability of the posts uploaded was highest for doctors at 3 and the least reliable posts were uploaded by dieticians, naturopathic doctors, and patients. This study found that the quality of posts uploaded by nutritionists and naturopathic doctors with a median Global Quality Score (GQS) score of 3. Conclusions There is a need to establish a quality control body that regulates the quality and reliability of the posts to curb misinformation and help patients gain easy access to reliable resources that will aid their decision-making.

RESUMO

INTRODUCTION: Polycystic ovary syndrome (PCOS), a chronic multifactorial disorder in women of reproductive age group, is a major public health problem. With most women resorting to platforms like "YouTube" that form a perfect source of edutainment, our aim was to analyze the quality of content available regarding the same. AIMS: The aims and objectives of this study were to assess the quality and reliability of content related to PCOS on YouTube by analyzing the DISCERN score, global quality score (GQS), and video power index (VPI). METHODOLOGY: It was a facility-based cross-sectional study undertaken on a single day with each author reviewing 10 videos from YouTube on PCOS using predetermined keywords. The number of likes, dislikes, views, comments, and uploader backgrounds were evaluated. DISCERN score, GQS, and VPI were also calculated for each video. While data entry was done using Microsoft Excel 2020 (Microsoft Corporation, Washington, United States), the analysis was carried out using SPSS Statistics version 16 (SPSS Inc. Released 2007. SPSS for Windows, Version 16.0. Chicago, SPSS Inc.). Categorical variables were expressed as frequency and percentages, and statistical significance was determined using the Kruskal-Wallis test/one-way ANOVA. RESULTS: A total of 80 videos that fit the inclusion criteria were analyzed. A majority of the videos (80%) were posted a year back with no updates. Only 28.8% of the video content was posted by doctors. Though most videos (96.25%) shared information pertaining to symptomatology, only 45% spoke regarding prevention. Promotional content was noted in 28.75% of the video content. GQS and VPI were better with information being provided by doctors, hospitals, and healthcare organizations (p-value 0.033 and 0.006, respectively). CONCLUSIONS: With women reaching out to edutainment platforms like YouTube to clarify their concerns surrounding lifestyle diseases such as PCOS in the digital era, it becomes relevant to evaluate the quality of content available on such platforms. The findings of the study form a prototype for addressing the existing gaps in the knowledge available on YouTube. Furthermore, the findings warrant frequent monitoring of such available web-based content and delivery of such content only from qualified wellness experts.

RESUMO

INTRODUCTION: Internet-based medical education plays a crucial role in bolstering public health awareness and the competence of medical professionals; however, it must be dependable. We aimed to examine the quality and reliability of the videos uploaded to YouTube (YouTube, LLC, San Bruno, California, United States) by professional healthcare professionals about scoliosis from 2014 to 2023. METHODS: The study was performed between August 1 and August 15, 2023. The keywords 'scoliosis', 'scoliosis-kyphosis brace', 'scoliosis exercises', 'scoliosis surgeries', and 'scoliosis-kyphosis exercises' were searched on YouTube. Only YouTube videos uploaded by healthcare professionals between January 1, 2014, and July 31, 2023, and only videos in the English language were examined. Video characteristics were evaluated and recorded for all videos. The quality and reliability of videos were assessed with two different questionnaire scales including the modified DISCERN score and the Global Quality Score (GQS). RESULTS: The mean number of views per video was 3778 in videos uploaded between 2014 and 2018, and 3120 in videos uploaded between 2019 and 2023 (p= 0.004). Video length and number of likes were statistically significantly lower in the videos of the last five years (p=0.001, and p=0.001). Thirty-one percent of the professional videos uploaded between 2014 and 2018 were directed at healthcare professionals. This rate was 12% in the last five years and was statistically significantly lower (p=0.001). The DISCERN score average was 3.7 between 2014 and 2018 and it was 3.2 between 2019 and 2023 (p=0.001). Similarly, the mean GQS was statistically significantly higher in the last five years compared to the five years prior (3.8 vs. 3.3, p=0.001). CONCLUSION: The present study determined that the quality and reliability of YouTube videos about scoliosis significantly increased in the last five years compared to the previous five years with a significant decrease in video duration. Also, among videos uploaded in the last five years, the number of videos for the patient was significantly higher. In contrast, the 'like' and 'view' numbers were significantly lower in YouTube videos about scoliosis in the last five years.

RESUMO

BACKGROUND: Hysteroscopy plays a crucial role in diagnosing and managing various intrauterine pathologies. However, its execution can be influenced by patients' perception and understanding, which are often shaped by digital resources such as YouTubeTM. Given its popularity and accessibility, YouTubeTM has the potential to greatly influence patients' knowledge and expectations about this procedure, highlighting the need for accurate and reliable information. PURPOSE: This study aims to assess the reliability and quality of hysteroscopy information available to patients on YouTubeTM. Understanding the nature of information patients' access can help address their fears and potential misunderstandings about the procedure, consequently reducing the likelihood of suspension or postponement due to anxiety. METHODS: A comprehensive analysis of YouTubeTM was conducted, simulating the search process of a patient seeking information about hysteroscopy. The study evaluated the reliability and quality of 90 out of the first 100 hysteroscopy-related videos on YouTubeTM, scored by four gynecologists-two experienced hysteroscopists and two trainees. The videos were assessed for reliability and quality using the mDISCERN and Global Quality Scale (GQS) scores. RESULTS: The average mDISCERN and GQS scores for the evaluated videos were below the optimal three points, highlighting the lack of fluency, comprehensiveness, and reliability of the available information. Notably, while videos produced by experts, including doctors and professional channels, had higher scores, they still fell short of the minimum score of 3. These videos also were not considered more suitable for either patients or trainees. Videos that were assessed as reliable (mDISCERN ≥ 3) were observed to be longer and were more frequently produced by doctors. These videos were suggested more to trainees rather than patients. Similarly, videos deemed as fluent and comprehensive (GQS ≥ 3) were longer and were more often recommended to patients. CONCLUSIONS: While YouTubeTM is a widely used source of medical information, the quality and reliability of hysteroscopy videos on the platform are poor. The strategic use of selected, high-quality hysteroscopy videos can enhance procedure success and alleviate patient fears. However, the unsupervised discovery of information by patients could potentially lead to procedure failure or an elevated level of stress due to misleading or incorrect information.

RESUMO

BACKGROUND: YouTube, known as an online video platform, is one of the most popular and dynamic video platforms in the world. it provides access to videos with a variety of content, both in health and many other areas. The fact that it is accessible to everyone and free of charge makes it frequently preferred by individuals. The effectiveness of social media platforms on the thoughts and behaviors of individuals has caused YouTube and other similar platforms to be the subject of health research in recent years. Agoraphobia is an anxiety disorder characterized by an intense fear of feeling trapped somewhere. Agoraphobia is a common type of anxiety disorder in society, and cognitive behavioral and psychopharmacological agents are used in its treatment. Our aim in this research is to examine YouTubeTM videos on agoraphobia in terms of reliability and quality. METHODS: The first 50 videos related to agoraphobia were included in the analysis, and the duration (minutes), video content, institutions/individuals who uploaded the video, the time elapsed since uploading, total views, and likes were recorded. In addition, all videos were evaluated on two different scales: Quality Criteria for Consumer Health Information (DISCERN) and the Global Quality Scale (GQS). The obtained data were analyzed statistically. RESULTS: The mean video duration was 11.4±9.38 minutes, the mean views count was 113299.5±333091, and the mean like count was 8512.76±31429.37. Videos were evaluated in terms of content; 50% included general information, 28% agoraphobia experience, and 22% information about overcoming agoraphobia. The GQS and DISCERN scores were significantly higher in professional videos than in non-professionals (p<0.005). CONCLUSION: As a result of the evaluation of YouTubeTM videos about agoraphobia in terms of quality and content, it has been determined that it is necessary to increase the rate of videos prepared by mental health professionals. Psychiatrists and other healthcare professionals working in the field of anxiety should be encouraged to provide videos with scientific and reliable content.

RESUMO

BACKGROUND: Liver cancer incidence has been increasing in China in the recent years, leading to increased public concern regarding the burden of this disease. Short videos on liver cancer are disseminated through TikTok and Bilibili apps, which have gained popularity in recent years as an easily accessible source of health information. However, the credibility, quality, and usefulness of the information in these short videos and the professional knowledge of the individuals uploading health information-based videos in these platforms have not yet been evaluated. OBJECTIVE: Our study aims to assess the quality of the information in Chinese short videos on liver cancer shared on the TikTok and Bilibili short video-sharing platforms. METHODS: In March 2023, we assessed the top 100 Chinese short videos on liver cancer in TikTok and Bilibili (200 videos in total) for their information quality and reliability by using 2 rating tools, namely, global quality score (GQS) and the DISCERN instrument. Correlation and Poisson regression analyses were applied to discuss the factors that could impact video quality. RESULTS: Compared to Bilibili, TikTok is more popular, although the length of the videos on TikTok is shorter than that of the videos on Bilibili (P<.001). The quality of the short videos on liver cancer in TikTok and Bilibili was not satisfactory, with median GQS of 3 (IQR 2-4) and 2 (IQR 1-5) and median DISCERN scores of 5 (IQR 4-6) and 4 (IQR 2-7), respectively. In general, the quality of videos sourced from professional institutions and individuals was better than that of those sourced from nonprofessionals, and videos involving disease-related knowledge were of better quality than those covering news and reports. No significant differences were found in the quality of videos uploaded by individuals from different professions, with the exception of those uploaded by traditional Chinese medicine professionals, which demonstrated poorer quality. Only video shares were positively correlated with the GQS (r=0.17, P=.01), and no video variables could predict the video quality. CONCLUSIONS: Our study shows that the quality of short videos on health information related to liver cancer is poor on Bilibili and TikTok, but videos uploaded by health care professionals can be considered reliable in terms of comprehensiveness and content quality. Thus, short videos providing medical information on TikTok and Bilibili must be carefully considered for scientific soundness by active information seekers before they make decisions on their health care management.

RESUMO

Aim Neonatal sepsis is a clinical syndrome of illness accompanied by bacteremia that develops in the first month of life. The objective of this study was to evaluate the reliability and quality of YouTubeTM (www.youtube.com) videos pertaining neonatal sepsis. Methods The first 100 videos on YouTubeTM pertaining to neonatal sepsis were included in the analysis. Features like videos' image type, content and qualification of video creators were recorded. In addition, videos' length, upload date, time since upload, comment and like counts were also recorded. Quality of the videos was measured by the researchers using the Global Quality Scale (GQS) and reliability of the videos was evaluated through the DISCERN (Quality Criteria for Consumer Health Information on Treatment Choices) tool. Results The total length of the examined 100 videos was 35.84 hours and the total view count was 1,173,247. The most common video content was general information about neonatal sepsis, education and diagnosis. When qualification of the video creators was examined, the most common creators were physicians followed by other persons and health channels. The videos were divided into two groups according to the creators. Accordingly, 40 (40%) videos were uploaded by professionals and 60 by non-professionals. There was a statistically significant difference between physicians and non-physicians in terms of the mean DISCERN and GQS scores (both, p<0.01). Conclusion Both DISCERN and GQS scores were statistically significantly higher in the videos provided by physicians. Physicians should be encouraged to upload accurate informative videos about neonatal sepsis and direct parents to accurate sources of treatment.

RESUMO

OBJECTIVES: To evaluate YouTube's usefulness as a source of information concerning pediatric tracheostomy care. MATERIALS AND METHODS: On August 10, 2022, the top 50 YouTube search results for "pediatric tracheostomy care" were displayed. Each video was evaluated by a jury of three otolaryngologists with at least 2 years of professional experience in pediatric otolaryngology using DISCERN, scoring system of Journal of the American Medical Association (JAMA), and the Global Quality Score (GQS). RESULTS: After exclusion criteria 24 videos were evaluated. Fifteen of the evaluated videos were produced by health professionals, and the other nine videos were produced by independent users. The average duration of the videos were 337.5 s, varying between 82 s and 1364 s. The average Discern score of videos produced by health professionals was 38.9 ± 13, compared to 36.6 ± 14 for independent users. The mean JAMA score was 1.04 ± 0.68 for health professionals and 1.11 ± 0.94 for independent users. The GQS score was 2.82 ± 0.73 for health professionals and 3.19 ± 0.84 for independent users. There was no statistically significant difference between the two groups for Discern, JAMA, and GQS scoring. CONCLUSION: YouTube does not seem to be a good option for parents to get useful information about pediatric tracheostomy care at this time. Health professionals should provide websites with high-quality materials to improve awareness of pediatric tracheostomy care.

RESUMO

Aim Magnetic resonance imaging (MRI)-induced anxiety is not infrequent with a reported incidence as high as 37% and the rate of failed MRI imaging due to claustrophobia ranges between 0.5% and 14.5%. The objective of this study was to evaluate the quality and reliability of YouTubeTM videos on MRI claustrophobia. Methods Sixty-five videos were included in the final analysis. Video information analyzed included video length (minutes), video content, qualification of the video uploaders, time of upload, time since upload, the number of total views and the mean daily views, and like counts. We divided the videos according to the uploaders into professional and non-professional groups and further grouped the videos as useful and misleading. Data obtained from the videos were evaluated with three tools including subjective evaluation, Quality Criteria for Consumer Health Information (DISCERN), and Global Quality Scale (GQS) tools. Results The mean video duration was found as 4.14±4.45 minutes. The mean view count was 104.59±408,788.68 and the mean like count was found as 272.55±1096.25. Seventeen (26.15%) videos were uploaded by professionals and 48 (73.85%) by non-professionals. Twenty-eight (43.08%) of the videos were useful and 37 (56.92%) were useless. The mean DISCERN and GQS scores were statistically significantly higher in the professional videos compared to the non-professional videos and in useful videos compared to non-useful videos (for all, p<0.001). Conclusion A majority of the YouTubeTM videos concerning MRI claustrophobia were uploaded by non-professionals. Physicians and other healthcare personnel should be encouraged to provide useful and accurate videos and to direct patients appropriately.

RESUMO

Background: Social media, with its low cost and easy accessibility, represents an ideal medium for sharing medical interests, but the quality of its content is questionable. Aim: The primary aim of this study was to evaluate the quality of video content related to vaginismus on YouTube as a source of information by using scores of established classification systems. The secondary aim was to examine the relationship between objective and subjective measures of their quality. Methods: The term vaginismus was typed into the YouTube search bar (http://www.youtube.com). The first 50 videos with the highest number of views were included in the study. All videos were assessed on August 18, 2022, by a gynecologist and/or a urologist experienced in vulvodynia. Data of all the videos were recorded, such as source, content, duration, day since upload date, number of views, number of likes, number of comments, and views per day. The Global Quality Scale (GQS) and modified DISCERN score were employed to assess the quality of the videos. Outcomes: The primary outcomes of this study were the scores of established classification systems and the measures relating to the preference and evaluation of viewers of YouTube videos on vulvodynia. Results: A total of 50 videos were evaluated. The sources of 32 (64%) of these videos were "universities/professional organizations/nonprofit physicians/physicians" and "stand-alone health information websites." The GQS and modified DISCERN scores of the videos whose source was "universities/professional organizations/nonprofit physicians/physicians" were higher than those whose source was "talk show programs/television programs" (P = .014 for GQS score, P = .046 for modified DISCERN score). When classified according to GQS score, the quality level of 58% of the videos was low. Of the videos whose source was "universities/professional organizations/nonprofit physicians/physicians," 56.3% were of good quality. Clinical Implications: The quality of information was very low and suggested that health care professionals should take on a more active role in configuring the qualitative characteristics of the material available online about the given health issues. Strengths and Limitations: To the best of our knowledge, this is the first study to investigate the quality of YouTube videos on vaginismus (vulvodynia). However, the limitation of this study is the relatively subjective evaluation of videos, including the risk of observer bias, although we attempted to overcome this problem with the inclusion of 2 independent reviewers and the use of validated tools. Conclusion: YouTube videos may offer a huge amount of information about this condition, but the quality of the available sources is heterogeneous.

RESUMO

Aim The objective of this study was to evaluate the reliability and quality of YouTube™ (Google, Inc., Mountain View, CA) videos pertaining to anaesthesia awareness. Methods We evaluated the most commonly viewed 100 videos pertaining to anaesthesia awareness. The YouTube™ videos' image type, qualification of the uploaders, video content, video length in minutes, upload time, time since upload, total view count, daily view count and comment and like counts were recorded. The quality of the YouTube™ videos was evaluated using the Global Quality Scale (GQS), and the reliability was determined using the modified DISCERN scale. Results Of all videos, 34 (34%) were uploaded directly by physicians, 16 (16%) by patients, 14 (14%) by health channels, 13 (13%) by TV shows and 23 (23%) by others. The mean video length was 11.48±11.96 minutes. The average DISCERN score was 4.47±0.58 in the professional and 3.28±0.65 in the non-professional video group (p<0.001). The mean GQS score was 4.47±0.52 in the professional and 3.35±0.67 in the non-professional video group (p<0.001). Conclusion The results of this study indicate that a significant portion of the YouTube™ videos pertaining to anaesthesia awareness were uploaded directly by physicians or by health channels. Physicians and professional health institutions should be promoted to provide accurate and more reliable videos to direct patients to the right solutions for their problems. YouTube™ videos should be subjected to supervision before they can be publicly viewed.

RESUMO

Objectives: The aim of the study was to clarify the reliability and quality of English videos about Coronary artery bypass grafting on YouTubeTM. Methods: The study was performed between July 16 and July 30. A cardiovascular surgeon searched for terms including "coronary artery disease," "coronary artery treatment," "coronary artery bypass" and "coronary artery bypass surgery," in YouTubeTM. All videos were classified into two groups according to the source who uploaded the video as professional videos and non-professional videos. Video characteristics including duration of video on YouTube™, length of video, and view numbers for each video were recorded. Moreover, the numbers of "comments," "likes," and "dislikes" were noted. Furthermore, the target audience of the videos (professional health care worker and patients) was analyzed, DISCERN score and Global quality score (GQS) were calculated for each video. Results: Totally, 812 videos were divided into two groups according to upload sources; 448 videos were categorized as professional videos and 364 videos were categorized as non-professional videos. The mean number of views was 3220.5 for professional videos and 2216.5 for non-professional videos (p=0.001). In addition, the mean "like" numbers and mean comment numbers were significantly higher for professional videos (p=0.001 and p=0.001). The mean DISCERN score was 2.6 for professional videos and 1.5 for non-professional videos (p=0.001). Similarly, the mean GSQ was significantly higher for professional videos (3.5 vs. 2.5, p=0.001). Conclusion: YouTube™ videos which are shared by professional healthcare workers have better quality and reliability with significantly higher DISCERN score and GQS.
