BACKGROUND: This study aims to assess the quality and reliability of the information for patients from YouTube videos on transforaminal interbody fusion (TLIF).
METHODS: One hundred videos were listed by inputting \"TLIF,\" \"TLIF surgery,\" and \"transforaminal interbody fusion\" in the YouTube search engine. The top 50 most popular videos based on video power index (VPI), view ratio, and exclusion criteria were selected for review. One orthopedic consultant surgeon and one neurosurgeon consultant analyzed the videos together. The modified DISCERN score, the Global Quality Score (GQS), the Journal of the American Medical Association (JAMA) score, and a novel interbody fusion score were used to evaluate videos. Data of video length, view count, number of likes and dislikes, like ratio (like x 100/(like+dislike)), video source, and comment rate were collected.
RESULTS: The quality of the videos could have been better according to all scoring systems, regardless of the video source. The scores of the videos published by patients and commercials were significantly lower than those of physicians and allied professionals (p <0.05). VPI and view ratios were similar in all sources.  Conclusion: The study demonstrates that YouTube videos providing information related to TLIF surgery are available and accessed by the public. The results of this study would suggest that YouTube is not currently an appropriate source of information on TLIF surgery for patients. Most of the YouTube videos about TLIF surgery contain information about the surgical technique and have limited information about the post-operative condition of the patients.

BACKGROUND: 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.
OBJECTIVE: 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).
METHODS: 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.

UNASSIGNED: The aim of the study was to clarify the reliability and quality of English videos about Coronary artery bypass grafting on YouTubeTM.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: YouTube™ videos which are shared by professional healthcare workers have better quality and reliability with significantly higher DISCERN score and GQS.
