BACKGROUND: The Magnetic Resonance Imaging (MRI) machine is a subset of nuclear magnetic resonance imaging technology that produces images of the body using magnetic field gradients. The MRI Machine has two components: the computer-based control centre room and the adjacent MRI machine room where the patient undergoes the scan.
OBJECTIVE: This study aimed to assess the quality and reliability of YouTube videos about MRI machines, MRI scans, and MRI claustrophobia and compare the quality and reliability of the videos among different types of uploaders.  Methodology: The YouTube Search Algorithm and a Google Sheets questionnaire were used to evaluate 10 videos that satisfied the inclusion criteria of the study. The video analytics included were title, number of views, likes and dislikes, comments, duration, source, and content. The quality of each video was established using the Global Quality Score (GQS), Reliability Score, and Video Power Index (VPI), where each quantifier went through statistical analysis using SPSS software, version 21.0 (IBM Corp., Armonk, NY) to determine if there was any significance.
RESULTS: In order to determine statistical differences between the groups, the Kruskal-Wallis test was used on the quantifiers GQS, reliability score, and VPI to generate p-values. The p-value for VPI is 0.467, GQS is 0.277, and reliability is 0.316. All the p-values are greater than 0.05, showing that there is no statistical support for any significant difference between the groups in their VPI, GQS and reliability scores.
CONCLUSIONS: YouTube videos with high-quality and reliable information on MRI machines, MRI procedures, and claustrophobia, especially those uploaded by clinicians and hospitals, can provide correct information, helping patients decide to undergo these procedures and alleviate claustrophobia.

BACKGROUND: YouTube serves as a good source of information on autism; however, the reliability and quality of such content remain uncertain. This study aimed to evaluate the reliability and quality of autism-related information presented in YouTube videos using the Global Quality Score (GQS) and Reliability Score.  Methods: A cross-sectional observational study was conducted in November 2023. A total of 48 autism-related videos on YouTube were sourced using keywords such as \'autism\', \'autism cause\', \'autism treatment\', and \'autism kids\'. The authors then viewed the videos and collected data regarding the number of views, likes and comments, uploader type, and type of information disseminated. The authors also used The GQS and modified DISCERN score to assess the quality and reliability of information in the videos. The data was then subjected to statistical analysis using the Kruskal-Wallis test and IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States).  Results: Out of 48 videos, seven videos were excluded, leaving 41 for analysis. The included videos amassed 25,540,635 views, 304,557 likes, and 37,039 comments. The majority of videos were uploaded by hospitals (n=15; 36.59%), followed by news channels (n=12; 29.27%). Most videos described autism symptoms (n=26; 63.41%), with fewer addressing potential etiology (n=16; 39.02%). The median GQS was highest for videos uploaded by healthcare professionals (n=5), contrasting with news channels. The Kruskal-Wallis test revealed significant differences (p=0.02).  Conclusion: These videos collectively garnered substantial viewership, likes, and comments. Most videos described autism symptoms, although fewer addressed potential causes. Notably, videos uploaded by healthcare professionals achieved the highest GQSs, highlighting their significance in disseminating reliable autism information. Healthcare professionals therefore play a crucial role in disseminating reliable autism information via YouTube. Encouraging their involvement in creating informative videos can enhance public understanding of autism.

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.

Introduction Bipolar disorder is a chronic and recurring condition marked by fluctuations in both energy and mood that can be debilitating to individuals without treatment. While physicians clinically diagnose the condition, patients frequently seek information from alternate channels. Social media platforms, such as Instagram, have facilitated more convenient access to supplementary information about bipolar disorder. Nevertheless, there is apprehension regarding the accuracy of publicly disseminated information through these platforms. The aim of this study is to evaluate the accuracy and dependability of information about Bipolar disorder found on the social media platform, Instagram. Methodology A cross-sectional observational study was conducted by gathering data from Instagram posts linked with popular bipolar disorder hashtags. To evaluate the credibility of the chosen entries, numerical ratings were assigned to each post using the established measurement scales of the Global Quality Score and Reliability Score. Results After analyzing 196 Instagram entries about Bipolar Disorder that fulfilled inclusion criteria, the study revealed that 70.4% (n=138) of these posts were shared by individuals diagnosed with bipolar disorder. Among the content posted by these individuals, a statistically significant global quality score of 2 and a reliability score of 1 were observed. Conclusions Verified medical information of superior global quality should be shared on social media platforms by accountable parties. Individuals with further inquiries about medical knowledge should be advised to reach out to local physicians.

Introduction Angiography is a method for defining the inner vessel wall and demonstrating flow through the lumen by detecting contrast injection into a blood vessel and projecting it onto a sequence of X-rays. This method is used to image the anatomical and architectural aspects of the vascular system. By employing balloon dilatation and the implantation of stents to widen the stenosed arteries, angioplasty is a form of minimally invasive endovascular treatment used to treat cardiovascular diseases and their consequences. People frequently rely on YouTube as a resource for awareness-raising and marketing activities. Animations and visual explanations can help patients understand the risks and benefits of procedures. Aims To assess the quality and reliability of the information on YouTube about angiography and angioplasty. We assessed quality using the GQS (Global Quality Scale) and reliability via the reliability score. Methodology This is an observational, cross-sectional study without the requirement of an ethics committee. It includes a questionnaire with predetermined criteria like time since upload, popularity, or type of uploader. The study assesses YouTube videos that include criteria using GQS and reliability scores. Responses recorded in Google Sheets were transferred to Microsoft Excel (Redmond, USA). Statistical analysis was performed using IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. All six authors assessed 10 YouTube videos using specific keywords. The study includes videos that meet the inclusion criteria. Videos that did not include the inclusion criteria were excluded. Results After applying inclusion/exclusion criteria, 57 out of 60 videos were included. Of the total videos analyzed, the majority were uploaded by various hospitals and people other than doctors and healthcare organizations. About 78.95% of the videos described the reason for angiography/plasty, followed by the anatomical area involved and the pre-procedural preparation phase. There is a significant increase in the GQS score and reliability score among the videos uploaded by doctors, hospitals, healthcare organizations, and other groups. Conclusions Verified health information should be uploaded responsibly by doctors, hospitals, healthcare organizations, or other agencies on social media like YouTube in a manner that is easy to understand, has a high GQS, and has a high reliability score, as it would make it simpler for the general population or viewers to have access to important health-related content they can rely on. Videos should advise the viewers to contact their doctors for all queries regarding the diagnosis or treatment of their health concerns.

BACKGROUND: Utilized in the healthcare sector, social media offers numerous benefits. However, its drawbacks encompass the variable quality of unregulated and unsupervised content. Thus, we aimed to evaluate the information in content related to chest pain found across Instagram and analyze the quality and reliability of chest pain-related content via Instagram posts.
METHODS: Instagram posts with content related to chest pain were analyzed with the help of a structured questionnaire that included the Global Quality Scale (GQS) and DISCERN score (DS). To collect Instagram posts, several distinct hashtags were employed: #chestpain, #chestpains, #angina, #anginatreatment, #heartattack, #heartattacksurvivor, #heartattackprevention.
RESULTS: A total of 262 posts were included, of which 29.7% of the total posts (n=78) contained information that describes the etiology of the disease. 27.8% of the total posts (n = 73) enclosed promotional content. Posts were found to be uploaded by doctors (18.7%), hospitals (15.6%), patients (17.9%), dieticians (11.1%), healthcare organizations (9.2%), and others (27.5%). Both Global Quality and DISCERN scores were statistically significant with a p-value of 0.001.
CONCLUSIONS: The findings of this study revealed that most of the Instagram content on chest pain posted via physicians were highly reliable and had a better global quality score. Information regarding various causes, symptoms and preventive measures on Instagram can be considered as an acceptable source for patients to surf on. A major limitation is that only English content was analyzed. In the future, the use of higher quality posts produced by healthcare professionals could potentially contribute to enhancing patient education via Instagram.

Introduction Diabetes mellitus (DM) encompasses a group of heterogeneous, chronic, and non-communicable diseases characterized by an increase in blood glucose levels. As it has become easily accessible for patients to know about their symptoms and treatment of diseases, it is of utmost importance that reliable information is conveyed on the internet. If not managed appropriately, it may result in the dissemination of false information, leading to risky practices and incorrect treatment, further resulting in detrimental consequences. Aim To assess the quality and reliability of information related to DM on YouTube. Methodology A cross-sectional observational study was conducted in April 2023, wherein top YouTube videos related to \'diabetes\' were analyzed for baseline characteristics, type of uploader, as well as quality and reliability using Global Quality Score (GQS) and Reliability Score (DISCEN), respectively. Statistical analysis was performed using SPSS software. Results A total of 87 videos were evaluated in the study. Unfortunately, only 21% of those were uploaded by doctors. The median Video Power Index (VPI) for videos uploaded by other sources was the highest (184.7), and the lowest was for videos uploaded by hospitals (12.6), and this was statistically significant (p = 0.038). The median GQS was highest for videos uploaded by doctors (4) and lowest for videos uploaded by others (3.5). The reliability score was higher in videos uploaded by healthcare organizations (4), which was not significant (p > 0.05). Conclusions Videos uploaded by physicians and healthcare organizations contained reliable information with a high global quality score. Videos uploaded by sources other than doctors and healthcare professionals should consult physicians, as self-diagnosis or self-treatment can lead to potential harm to patients.

BACKGROUND: This study aims to assess the quality and reliability of the disease information available on YouTube (www.youtube.com) about \"heart attacks\" or myocardial infarctions, using a Global Quality Score (GQS) for quality, a DISCERN score for reliability, and a Video Power Index (VPI) for popularity.
METHODS: In this cross-sectional observational study, the YouTube videos were analyzed in terms of the type of uploader, content, and other factors. The GQS, DISCERN score, and Video Power Index (VPI) were utilized to assess the quality, reliability, and popularity of the information, respectively.
RESULTS: The majority of the videos (78.44%) were uploaded over a year ago. Only 33.34% and 7.84% were uploaded by doctors and healthcare organizations, respectively. Around 72.55% of the videos contained information about symptoms, 66.67% discussed the causes, 52.94% covered treatment, and 47.06% focused on prevention. Additionally, 41.18% provided details on investigations, while only 19.61% touched upon mortality. Patient-created videos accounted for 19.61% of the content, and 15.69% of the videos included promotional material.
CONCLUSIONS: The main outcome of our study indicates that the YouTube videos examined regarding myocardial infarctions exhibit high-quality content, as supported by a higher average GQS score. The consistent quality of information discovered in our study suggests that YouTube can serve as an additional platform for sharing knowledge and educating individuals about this important health condition. By raising awareness and delivering accurate information, these videos can help in early detection, prevention, and better outcomes for individuals who are at risk of experiencing a myocardial infarction.

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.
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.
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.
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.
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.
