To investigate whether YouTube videos on pharmacokinetics can be a useful learning resource for medical students. YouTube was searched from 01 November to 15 November 2013 for search terms "Pharmacokinetics", "Drug absorption", "Drug distribution", Drug metabolism", "Drug elimination", "Biliary excretion of drugs", and "Renal excretion of drugs".  Only videos in the English and those matching the inclusion criteria were included. For each video, the following characteristic data were collected: title, URL, duration, number of viewers, date uploaded, and viewership per day, like, dislike, number of comments, number of video sharing, and the uploader /creator. Using standardized criteria comprising technical, content, authority and pedagogy parameters, three evaluators independently assessed the videos for educational usefulness. Data were analyzed using SPSS software and the agreement between the evaluators was calculated using Cohen's kappa analysis. The search identified 1460 videos. Of these, only 48 fulfilled the inclusion criteria. Only 30 were classified as educationally useful videos (62.5%) scoring 13.83±0.45 (mean±SD) while the remaining 18 videos were not educationally useful (37.5%) scoring 6.48±1.64 (mean±SD), p = 0.000. The educationally useful videos were created by pharmacologists/educators 83.3% (25/30), professors from two universities 13.3% (04/30) and private tutoring body 3.3% (01/30). The useful videos were viewed by 12096 (65.4%) and had a total of 433332 days on YouTube, while the non-educationally useful videos were viewed by 6378 (34.6%) viewers and had 20684 days on YouTube. No correlation was found between video total score and number of like (R2 0.258), dislike (R2 0.103), viewers (R2 0.186), viewership/day (R2 0.256), comments (R2 0.250), or share (R2 0.174). The agreement between the three evaluators had an overall Cohen's kappa score in the range of 0.582-0.949. YouTube videos on pharmacokinetics and drug elimination showed a

Approximately 5.5 million Americans are living with Alzheimer's disease (AD) in 2017. YouTube is a popular platform for disseminating health information; however, little is known about messages specifically regarding AD that are being communicated through YouTube. This study aims to examine video characteristics, content, speaker characteristics, and mobilizing information (cues to action) of YouTube videos focused on AD. Videos uploaded to YouTube from 2013 to 2015 were searched with the term "Alzheimer's disease" on April 30th, 2016. Two coders viewed the videos and coded video characteristics (the date when a video was posted, Uniform Resource Locator, video length, audience engagement, format, author), content, speaker characteristics (sex, race, age), and mobilizing information. Descriptive statistics were used to examine video characteristics, content, audience engagement (number of views), speaker appearances in the video, and mobilizing information. Associations between variables were examined using Chi-square and Fisher's exact tests. Among the 271 videos retrieved, 25.5% (69/271) were posted by nonprofit organizations or universities. Informal presentations comprised 25.8% (70/271) of all videos. Although AD symptoms (83/271, 30.6%), causes of AD (80/271, 29.5%), and treatment (76/271, 28.0%) were commonly addressed, quality of life of people with AD (34/271, 12.5%) had more views than those more commonly-covered content areas. Most videos featured white speakers (168/187, 89.8%) who were adults aged 20 years to their early 60s (164/187, 87.7%). Only 36.9% (100/271) of videos included mobilizing information. Videos about AD symptoms were significantly less likely to include mobilizing information compared to videos without AD symptoms (23/83, 27.7% vs 77/188, 41.0% respectively; P=.03). This study contributes new knowledge regarding AD messages delivered through YouTube. Findings of the current study highlight a potential gap between available information

Usage of YouTube as an educational tool is gaining attention in academic research. To date, there has been no study on the content and quality of eye surgery videos on YouTube. The aim of this study was to analyze YouTube videos on phacoemulsification in eyes with small pupil. We searched for the phrases "small pupil cataract surgery," "small pupil phacoemulsification," "small pupil cataract surgery complications," and "small pupil phacoemulsification complications" in January 2015. Each resulting video was evaluated by all authors, and Krippendorff's alpha was calculated to measure agreement. Videos were classified according to pupil size (small/very small) in the beginning of the surgery, and whether pupillary diameter was large enough to continue surgery safely after pupillary dilation by the surgeon in the video (safe/not safe). Methods of dilatation were also analyzed. Any stated ocular comorbidity or surgical complications were noted. A total of 96 videos were reviewed. No mechanical intervention for pupillary dilatation was performed in 46 videos. Fifty-eight operated eyes had no stated ocular comorbidity. Ninety-five operations ended successfully without major complication. There was fair agreement between the evaluators regarding pupil sizes (Kα = 0.670) but poor agreement regarding safety (Kα = 0.337). YouTube videos on small pupil phacoemulsification have low complication rates when compared to the literature, although no reliable mechanical dilatation methods are used in almost half of these videos. Until YouTube's place in e-learning becomes clearer, we suggest that viewers be cautious regarding small pupil phacoemulsification videos on YouTube.

Direct ophthalmoscopy is well-suited for video-based instruction, particularly if the videos enable the student to see what the examiner sees when performing direct ophthalmoscopy. We evaluated the pedagogical effectiveness of instructional YouTube videos on direct ophthalmoscopy by evaluating their content and approach to visualization. In order to synthesize main themes and points for direct ophthalmoscopy, we formed a broad panel consisting of a medical student, junior and senior physicians, and took into consideration book chapters targeting medical students and physicians in general. We then systematically searched YouTube. Two authors reviewed eligible videos to assess eligibility and extract data on video statistics, content, and approach to visualization. Correlations between video statistics and contents were investigated using two-tailed Spearman's correlation. We screened 7,640 videos, of which 27 were found eligible for this study. Overall, a median of 12 out of 18 points (interquartile range: 8-14 key points) were covered; no videos covered all of the 18 points assessed. We found the most difficulties in the approach to visualization of how to approach the patient and how to examine the fundus. Time spent on fundus examination correlated with the number of views per week (Spearman's ρ=0.53; P=0.029). Videos may help overcome the pedagogical issues in teaching direct ophthalmoscopy; however, the few available videos on YouTube fail to address this particular issue adequately. There is a need for high-quality videos that include relevant points, provide realistic visualization of the examiner's view, and give particular emphasis on fundus examination.

Portrayal of tobacco in Mongolian language YouTube videos: policy gaps.

This study examined how effectively current policy measures control depictions of tobacco in Mongolian language YouTube videos. A search of YouTube videos using the Mongolian term for 'tobacco', and employing 'relevance' and 'view count' criteria, resulted in a total sample of 120 videos, from which 38 unique videos were coded and analysed. Most videos were antismoking public service announcements; however, analyses of viewing patterns showed that pro-smoking videos accounted for about two-thirds of all views. Pro-smoking videos were also perceived more positively and had a like:dislike ratio of 4.6 compared with 3.5 and 1.5, respectively, for the magic trick and antismoking videos. Although Mongolia prohibits tobacco advertising, 3 of the pro-smoking videos were made by a tobacco company; additionally, 1 pro-smoking video promoted electronic cigarettes. Given the popularity of Mongolian YouTube videos that promote smoking, policy changes are urgently required to control this medium, and more effectively protect youth and young adults from insidious tobacco marketing.

Antiretroviral (ARV) medicines reduce the risk of transmitting the HIV virus and are recommended as daily pre-exposure prophylaxis (PrEP) in combination with safer sex practices for HIV-negative individuals at a high risk for infection, but are underused in HIV prevention. Previous literature suggests that YouTube is extensively used to share health information. While pre-exposure prophylaxis (PrEP) is a novel and promising approach to HIV prevention, there is limited understanding of YouTube videos as a source of information on PrEP. The objective of this study was to describe the sources, characteristics, and content of the most widely viewed PrEP YouTube videos published up to October 1, 2016. The keywords "pre-exposure prophylaxis" and "Truvada" were used to find 217 videos with a view count >100. Videos were coded for source, view count, length, number of comments, and selected aspects of content. Videos were also assessed for the most likely target audience. The total cumulative number of views was >2.3 million, however, a single Centers for Disease Control and Prevention video accounted for >1.2 million of the total cumulative views. A great majority (181/217, 83.4%) of the videos promoted the use of PrEP, whereas 60.8% (132/217) identified the specific target audience. In contrast, only 35.9% (78/217) of the videos mentioned how to obtain PrEP, whereas less than one third addressed the costs, side effects, and safety aspects relating to PrEP. Medical and academic institutions were the sources of the largest number of videos (66/217, 30.4%), followed by consumers (63/217, 29.0%), community-based organizations (CBO; 48/217, 22.1%), and media (40/217, 18.4%). Videos uploaded by the media sources were more likely to discuss the cost of PrEP (P<.001), whereas the use of PrEP was less likely to be promoted in videos uploaded by individual consumers (P=.002) and more likely to be promoted in videos originated by CBOs (P=.009).

Entry of terms reflective of extreme risky driving behaviors into the YouTube website yields millions of videos. The majority of the top 20 highly subscribed automotive YouTube websites are focused on high-performance vehicles, high speed, and often risky driving. Moreover, young men are the heaviest users of online video sharing sites, overall streaming more videos, and watching them longer than any other group. The purpose of this article is to review the literature on YouTube videos and risky driving. A systematic search was performed using the following specialized database sources-Scopus, PubMed, Web of Science, ERIC, and Google Scholar-for the years 2005-2015 for articles in the English language. Search words included "YouTube AND driving," "YouTube AND speeding," "YouTube AND racing." No published research was found on the content of risky driving videos or on the effects of these videos on viewers. This literature review presents the current state of our published knowledge on the topic, which includes a review of the effects of mass media on risky driving cognitions; attitudes and behavior; similarities and differences between mass and social media; information on the YouTube platform; psychological theories that could support YouTube's potential effects on driving behavior; and 2 examples of risky driving behaviors ("sidewalk skiing" and "ghost riding the whip") suggestive of varying levels of modeling behavior in subsequent YouTube videos. Every month about 1 billion individuals are reported to view YouTube videos (ebizMBA Guide 2015 ) and young men are the heaviest users, overall streaming more YouTube videos and watching them longer than women and other age groups (Nielsen 2011 ). This group is also the most dangerous group in traffic, engaging in more per capita violations and experiencing more per capita injuries and fatalities (e.g., Parker et al. 1995 ; Reason et al. 1990 ; Transport Canada 2015 ; World Health Organization 2015 ).

This study examines (1) how the topics of obesity are framed and (2) how obese persons are portrayed on YouTube video clips. The analysis of 417 obesity videos revealed that a newer medium like YouTube, similar to traditional media, appeared to assign responsibility and solutions for obesity mainly to individuals and their behaviors, although there was a tendency that some video categories have started to show other causal claims or solutions. However, due to the prevailing emphasis on personal causes and solutions, numerous YouTube videos had a theme of weight-based teasing, or showed obese persons engaging in stereotypical eating behaviors. We discuss a potential impact of YouTube videos on shaping viewers' perceptions about obesity and further reinforcing stigmatization of obese persons.

Patients interested in botulinum toxin type A (BTX-A) for wrinkles search for videos on YouTube, but little is known about the quality and reliability of the content. The authors examined the quality, reliability, content, and target audience of YouTube videos on BTX for wrinkles. In this cross-sectional study, the term "Botox" was searched on YouTube. Sixty relevant videos in English were independently categorized by 2 reviewers as useful informational, misleading informational, useful patient view, or misleading patient view. Disagreements were settled by a third reviewer. Videos were rated on the Global Quality Scale (GQS) (1 = poor, 5 = excellent). Sixty-three percent of the BTX YouTube videos were useful informational (GQS = 4.4 ± 0.7), 33% as useful patient view (GQS = 3.21 ± 1.2), 2% as misleading informational (GQS = 1), and 2% as misleading patient view (GQS = 2.5). The large number of useful videos, high reliability, and the wide range of content covered suggests that those who search for antiwrinkle BTX videos on YouTube are likely to view high-quality content. This suggests that YouTube may be a good source of videos to recommend for patients interested in BTX.

To analyze the videos on the YouTube video sharing site, noting which points addressed in the videos related to CPR and BLS, based on the 2010 Guidelines for the American Heart Association (AHA). This was an exploratory, quantitative and qualitative research performed in the YouTube sharing site, using as keywords the expressions in Portuguese equivalent to the Medical Subject Headings (MeSH) "Cardiopulmonary Resuscitation" and "Basic Life Support" for videos that focused on the basic life support. The research totaled 260 videos over the two searches. Following the exclusion criteria, 61 videos remained. These mostly are posted by individuals and belong to the category Education. Moreover, most of the videos, despite being added to the site after the publication of the 2010 AHA Guidelines, were under the older 2005 guidelines. Although the video-sharing site YouTube is widely used today, it lacks videos about CPR and BLS that comply to the most recent AHA recommendations, which may negatively influence the population that uses it.

Video-sharing social media like YouTube provide access to diverse cultural products from all over the world, making it possible to test theories that the Web facilitates global cultural convergence. Drawing on a daily listing of YouTube's most popular videos across 58 countries, we investigate the consumption of popular videos in countries that differ in cultural values, language, gross domestic product, and Internet penetration rate. Although online social media facilitate global access to cultural products, we find this technological capability does not result in universal cultural convergence. Instead, consumption of popular videos in culturally different countries appears to be constrained by cultural values. Cross-cultural convergence is more advanced in cosmopolitan countries with cultural values that favor individualism and power inequality.

The purpose of this study was to conduct a descriptive analysis of music therapy-related videos on YouTube. Preliminary searches using the keywords music therapy, music therapy session, and "music therapy session" resulted in listings of 5000, 767, and 59 videos respectively. The narrowed down listing of 59 videos was divided between two investigators and reviewed in order to determine their relationship to actual music therapy practice. A total of 32 videos were determined to be depictions of music therapy sessions. These videos were analyzed using a 16-item investigator-created rubric that examined both video specific information and therapy specific information. Results of the analysis indicated that audio and visual quality was adequate, while narrative descriptions and identification information were ineffective in the majority of the videos. The top 5 videos (based on the highest number of viewings in the sample) were selected for further analysis in order to investigate demonstration of the Professional Level of Practice Competencies set forth in the American Music Therapy Association (AMTA) Professional Competencies (AMTA, 2008). Four of the five videos met basic competency criteria, with the quality of the fifth video precluding evaluation of content. Of particular interest is the fact that none of the videos included credentialing information. Results of this study suggest the need to consider ways to ensure accurate dissemination of music therapy-related information in the YouTube environment, ethical standards when posting music therapy session videos, and the possibility of creating AMTA standards for posting music therapy related video.

We evaluated videos on the social media website, YouTube, containing references to seizures and epilepsy. Of 100 videos, 28% contained an ictal event, and 25% featured a person with epilepsy recounting his or her personal experience. Videos most commonly fell into categories of Personal Experience/Anecdotal (44%) and Informative/Educational (38%). Fifty-one percent of videos were judged as accurate, and 9% were inaccurate; accuracy was not an applicable attribute in the remainder of the videos. Eighty-five percent of videos were sympathetic towards those with seizures or epilepsy, 9% were neutral, and only 6% were derogatory. Ninety-eight percent of videos were thought to be easily understood by a layperson. The user-generated content on YouTube appears to be more sympathetic and accurate compared to other forms of mass media. We are optimistic that with a shifting ratio towards sympathetic content about epilepsy, the amount of stigma towards epilepsy and seizures will continue to lessen. Copyright © 2013 Elsevier Inc.

Background When making decisions about medication use in pregnancy, women consult many information sources, including the Internet. The aim of this study was to assess the content of publicly-accessible YouTube videos that discuss medication use in pregnancy. Methods Using 2,023 distinct combinations of search terms related to medications and pregnancy, we extracted metadata from YouTube videos using a YouTube video Application Programming Interface. Relevant videos were defined as those with a medication search term and a pregnancy-related search term in either the video title or description. We viewed relevant videos and abstracted content from each video into a database. We documented whether videos implied each medication to be ‘safe’ or ‘unsafe’ in pregnancy and compared that assessment with the medication’s Teratogen Information System (TERIS) rating. Results After viewing 651 videos, 314 videos with information about medication use in pregnancy were available for the final analyses. The majority of videos were from law firms (67%), television segments (10%), or physicians (8%). Selective serotonin reuptake inhibitors (SSRIs) were the most common medication class named (225 videos, 72%), and 88% percent of videos about SSRIs indicated they were ‘unsafe’ for use in pregnancy. However, the TERIS ratings for medication products in this class range from ‘unlikely’ to ‘minimal’ teratogenic risk. Conclusion For the majority of medications, current YouTube video content does not adequately reflect what is known about the safety of their use in pregnancy and should be interpreted cautiously. However, YouTube could serve as a valuable platform for communicating evidence-based medication safety information. PMID:26541372

The growing number of bariatric surgery videos shared on YouTube highlights the need for content and quality assessment. The aim of this study was to answer the question 'Is watching these videos useful to surgeons and patients?' YouTube was searched using the keywords 'obesity surgery', 'bariatric surgery' and 'weight loss surgery', and 100 videos retrieved using each keyword were classified based on their 'usefulness score' as very useful, useful and not useful. Video content; source; length and number of views, likes and dislikes were recorded. Upload sources included doctors or hospitals (DH), medical web sites or TV channels (MW), commercial web sites (CW) or civilians (CI). Between-group differences were compared. Of the 300 videos watched, 175 were included in the study; 53.7% were useful and 24.6% were very useful. There were no between-group differences in the number of likes (p = 0.480), dislikes (p = 0.592) and views (p = 0.104). Most videos were uploaded by MW and DH, also with no significant differences in the number of likes (p = 0.35), dislikes (p = 0.14) and views (p = 0.93). No videos were found with misleading information. The popularity of bariatric surgery and interest of both patients and surgeons are increasing daily. Although videos on bariatric surgery on YouTube may be more useful than those on other surgical procedures, it is important that the videos are uploaded by medical professionals and that specific upload and retrieval filters are applied.

YouTube is one of the largest social networking websites, allowing users to upload and view video content that provides entertainment and conveys many messages, including those related to health conditions, such as concussion. However, little is known about the content of videos relating to concussion. To identify and classify the content of concussion-related videos available on YouTube. An observational study using content analysis. YouTube's video database was systematically searched using 10 search terms selected from MeSH and Google Adwords. The 100 videos with the largest view counts were chosen from the identified videos. These videos and their accompanying text were analysed for purpose, source and description of content by a panel of assessors who classified them into data-driven thematic categories. 434 videos met the inclusion criteria and the 100 videos with the largest view counts were chosen. The most common categories of the videos were the depiction of a sporting injury (37%) and news reports (25%). News and media organisations were the predominant source (51%) of concussion-related videos on YouTube, with very few being uploaded by professional or academic organisations. The median number of views per video was 26 191. Although a wide range of concussion-related videos were identified, there is a need for healthcare and educational organisations to explore YouTube as a medium for the dissemination of quality-controlled information on sports concussion.

Rapp, Allison K; Healy, Michael G; Charlton, Mary E; Keith, Jerrod N; Rosenbaum, Marcy E; Kapadia, Muneera R

The purpose of this study was to evaluate surgical preparation methods of medical students, residents, and faculty with special attention to video usage. Following Institutional Review Board approval, anonymous surveys were distributed to participants. Information collected included demographics and surgical preparation methods, focusing on video usage. Participants were questioned regarding frequency and helpfulness of videos, video sources used, and preferred methods between videos, reading, and peer consultation. Statistical analysis was performed using SAS. Surveys were distributed to participants in the Department of Surgery at the University of Iowa Hospitals and Clinics, a tertiary care center in Iowa City, Iowa. Survey participants included fourth-year medical students pursuing general surgery, general surgery residents, and faculty surgeons in the Department of Surgery. A total of 86 surveys were distributed, and 78 surveys were completed. This included 42 learners (33 residents, 9 fourth-year medical students) and 36 faculty. The overall response rate was 91%; 90% of respondents reported using videos for surgical preparation (learners = 95%, faculty = 83%, p = NS). Regarding surgical preparation methods overall, most learners and faculty selected reading (90% versus 78%, p = NS), and fewer respondents reported preferring videos (64% versus 44%, p = NS). Faculty more often use peer consultation (31% versus 50%, p < 0.02). Among respondents who use videos (N = 70), the most used source was YouTube (86%). Learners and faculty use different video sources. Learners use YouTube and Surgical Council on Resident Education (SCORE) Portal more than faculty (YouTube: 95% versus 73%, p < 0.02; SCORE: 25% versus 7%, p < 0.05). Faculty more often use society web pages and commercial videos (society: 67% versus 38%, p < 0.03; commercial: 27% versus 5%, p < 0.02). Most respondents reported using videos to prepare for surgery. YouTube was the preferred source. Posting

To evaluate the clinical accuracy and delivery of information on thermal burn first aid available on the leading video-streaming website, YouTube. YouTube was searched using four separate search terms. The first 20 videos identified for each search term were included in the study if their primary focus was on thermal burn first aid. Videos were scored by two independent reviewers using a standardised scoring system and the scores totalled to give each video an overall score out of 20. A total of 47 videos were analysed. The average video score was 8.5 out of a possible 20. No videos scored full-marks. A low correlation was found between the score given by the independent reviewers and the number of views the video received per month (Spearman's rank correlation co-efficient=0.03, p=0.86). The current standard of videos covering thermal burn first aid available on YouTube is unsatisfactory. In addition to this, viewers do not appear to be drawn to videos of higher quality. Organisations involved in managing burns and providing first aid care should be encouraged to produce clear, structured videos that can be made available on leading video streaming websites.

Recent content analyses of YouTube postings reveal a proliferation of user generated videos with misleading statements about the health consequences of various types of nontraditional tobacco use (eg, electronic cigarettes; e-cigarettes). This research was aimed at obtaining evidence about the potential effects of YouTube postings about tobacco products on viewers' attitudes toward these products. A sample of young adults recruited online (N=350) viewed one of four highly viewed YouTube videos containing misleading health statements about chewing tobacco, e-cigarettes, hookahs, and pipe smoking, as well as a control YouTube video unrelated to tobacco products. The videos about e-cigarettes and hookahs led to more positive attitudes toward the featured products than did control videos. However, these effects did not fully translate into attitudes toward combustive cigarette smoking, although the pipe video led to more positive attitudes toward combustive smoking than did the chewing and the hookah videos, and the e-cigarette video led to more positive attitudes toward combustive cigarette smoking than did the chewing video. This research revealed young people's reactions to misleading claims about tobacco products featured in popular YouTube videos. Policy implications are discussed. ©Dolores Albarracin, Daniel Romer, Christopher Jones, Kathleen Hall Jamieson, Patrick Jamieson.

To investigate attitudes towards schizophrenia and people with schizophrenia presented in YouTube videos. We searched YouTube using the search terms "schizophrenia" and "psychosis" in Finnish and Greek language on April 3rd, 2013. The first 20 videos from each search (N = 80) were retrieved. Deductive content analysis was first applied for coding and data interpretation and it was followed by descriptive statistical analysis. A total of 52 videos were analyzed (65%). The majority of the videos were in the "Music" category (50%, n = 26). Most of the videos (83%, n = 43) tended to present schizophrenia in a negative way, while less than a fifth (17%, n = 9) presented schizophrenia in a positive or neutral way. Specifically, the most common negative attitude towards schizophrenia was dangerousness (29%, n = 15), while the most often identified positive attitude was objective, medically appropriate beliefs (21%, n = 11). All attitudes identified were similarly present in the Finnish and Greek videos, without any statistically significant difference. Negative presentations of schizophrenia are most likely to be accessed when searching YouTube for schizophrenia in Finnish and Greek language. More research is needed to investigate to what extent, if any, YouTube viewers' attitudes are affected by the videos they watch.

To assess the depiction of e-cigarettes in YouTube videos. The sample (N = 63) was selected from the top 20 search results for "electronic cigarette," and "e-cig" with each term searched twice by the filters "Relevance" and "View Count." Data collected included title, length, number of views, "likes," "dislikes," comments, and inferred demographics of individuals appearing in the videos. Seventy-six percent of videos included at least one man, 62% included a Caucasian, and 50% included at least one young individual. Video content connotation was coded as positive (76%), neutral (18%), or negative (6%). Videos were categorized as advertisement (33%), instructional (17%), news clip (19%), product review (13%), entertainment (11%), public health (3%), and personal testimonial (3%). Most e-cigarette YouTube videos are non-traditional or covert advertisements featuring young Caucasian men.

2016-05-01

The aim of this study is to identify and evaluate the quality of videos for patients available on YouTube for learning to self-administer subcutaneous methotrexate. Using the search term "Methotrexate injection," two clinical reviewers analyzed the first 60 videos on YouTube. Source and search rank of video, audience interaction, video duration, and time since video was uploaded on YouTube were recorded. Videos were classified as useful, misleading, or a personal patient view. Videos were rated for reliability, comprehensiveness, and global quality scale (GQS). Reasons for misleading videos were documented, and patient videos were documented as being either positive or negative towards methotrexate (MTX) injection. Fifty-one English videos overlapped between the two geographic locations; 10 videos were classified as useful (19.6 %), 14 misleading (27.5 %), and 27 personal patient view (52.9 %). Total views of videos were 161,028: 19.2 % useful, 72.8 % patient, and 8.0 % misleading. Mean GQS: 4.2 (±1.0) useful, 1.6 (±1.1) misleading, and 2.0 (±0.9) for patient videos (p < 0.0001). Mean reliability: 3.3 (±0.6) useful, 0.9 (±1.2) misleading, and 1.0 (±0.7) for patient videos (p < 0.0001). Comprehensiveness: 2.2 (±1.9) useful, 0.1 (±0.3) misleading, and 1.5 (±1.5) for patient view videos (p = 0.0027). This study demonstrates a minority of videos are useful for teaching MTX injection. Further, video quality does not correlate with video views. While web video may be an additional educational tool available, clinicians need to be familiar with specific resources to help guide and educate their patients to ensure best outcomes.

Clinical trials are essential to the advancement of cancer treatment but fewer than 5% of adult cancer patients enroll in a trial. A commonly cited barrier to participation is the lack of understanding about clinical trials. Since the internet is a popular source of health-related information and YouTube is the second most visited website in the world, we examined the content of the top 115 YouTube videos about clinical trials to evaluate clinical trial information available through this medium. YouTube videos posted prior to March 2017 were searched using selected keywords. A snowballing technique was used to identify videos wherein sequential screening of the autofill search results for each set of keywords was conducted. Video characteristics (eg, number of views and video length) were recorded. The content was broadly grouped as related to purpose, phases, design, safety and ethics, and participant considerations. Stepwise multivariable logistic regression analysis was conducted to assess associations between video type (cancer vs noncancer) and video characteristics and content. In total, 115 videos were reviewed. Of these, 46/115 (40.0%) were cancer clinical trials videos and 69/115 (60.0%) were noncancer/general clinical trial videos. Most videos were created by health care organizations/cancer centers (34/115, 29.6%), were oriented toward patients (67/115, 58.3%) and the general public (68/115, 59.1%), and were informational (79/115, 68.7%); altruism was a common theme (31/115, 27.0%). Compared with noncancer videos, cancer clinical trials videos more frequently used an affective communication style and mentioned the benefits of participation. Cancer clinical trial videos were also much more likely to raise the issue of costs associated with participation (odds ratio [OR] 5.93, 95% CI 1.15-29.46) and advise patients to communicate with their physician about cancer clinical trials (OR 4.94, 95% CI 1.39-17.56).

Internet is a resource to search for health-related information. The aim of this work was to know the content of the videos in Spanish language of YouTube related to the vaccine against the human papilloma virus (HPV). An observational study was conducted from a search on YouTube on 26th July 2013 by using keywords such as: "human papilloma virus vaccine", "HPV vaccine", "Gardasil vaccine", "Cervarix vaccine". Different categories were established according to: the type of vaccine, the published source and the favorable or unfavorable predisposition towards the human papillomavirus vaccination. The number of visits and the duration of the videos were gathered, with analysis of variables in the 20 most visited videos. A total of 170 videos were classified like: local news (n=39; 37 favorable, 2 unfavorable; 2:06:29; 42972 visits), national news (n=32; 30/2; 1:49:27; 50138 visits), created by YouTube subscribers (n=21; 21/1; 1:44:39; 10991 visits), advertisements (n=21; 19/2; 0:27:05; 28435 visits), conferences (n=17; 15/2; 3:25:39; 27206 visits), documentaries (n=16; 12/4; 2:11:31; 30629 visits). From all of the 20 most viewed YouTube videos predominated those which were favorable to the vaccination (n=12; 0:43:43; 161789 visits) against the unfavorable (n=8; 2:44:14; 86583 visits). Most of the videos have a favorable opinion towards HPV vaccine, although videos with a negative content were the longest and most viewed.

YouTube: a promotional vehicle for little cigars and cigarillos?

Richardson, Amanda; Vallone, Donna M

2014-01-01

As the third most popular website in the world, messages embedded in the video-sharing site, YouTube, have the potential to influence tobacco-related attitudes, beliefs and behaviours. Despite the growing number of videos depicting little cigars/cigarillos (LCCs), there has been no examination of the portrayal of these products on YouTube. Researchers identified up to the top 20 search results on YouTube by relevance and view count for the following search terms: 'little cigars', 'cigarillos', 'Black and Mild', 'Swisher Sweets', 'White owl', 'Garcia y Vega', and 'Winchester'. Reviewers rated whether videos were 'pro', 'anti' or 'neutral' to the use of LCCs, and documented statistics on the reach and viewer demographics. Several main themes around LCCs were noted, as was video quality (amateur vs professional) and demographics of video participants. Of the 196 videos retrieved, only 56 were unique, eligible videos. The majority of these (n=43) were 'pro' LCCs, 11 were 'neutral', and only two were 'anti' LCCs. Videos were primarily viewed by males in the USA and Canada and most were amateur. Common themes included where to purchase LCCs, their candy flavours, and that they are cheap or cheaper than cigarettes, and 'smooth'. The vast majority of information on YouTube about LCCs promotes their use. It is critical to monitor content on LCCs posted on YouTube, and develop appropriate health messages to counter pro-LCC content, and appropriately inform potential consumers of the harms associated with their use.

Recent research revealed diverse content and varying levels of quality in YouTube music therapy videos and prompted questions about viewers' discrimination abilities. This study compares ratings of a YouTube music therapy session video by viewers with different levels of music therapy expertise to determine video elements related to perceptions of representational quality. Eighty-one participants included 25 novices (freshmen and sophomores in an introductory music therapy course), 25 pre-interns (seniors and equivalency students who had completed all core Music Therapy courses), 26 professionals (MT-BC or MT-BC eligibility) with a mean of 1.75 years of experience, and an expert panel of 5 MT-BC professionals with a mean of 11 years of experience in special education. After viewing a music therapy special education video that in previous research met basic competency criteria and professional standards of the American Music Therapy Association, participants completed a 16-item questionnaire. Novices' ratings were more positive (less discriminating) compared to experienced viewers' neutral or negative ratings. Statistical analysis (ANOVA) of novice, pre-intern, and professional ratings of all items revealed significant differences p, .05) for specific therapy content and for a global rating of representational quality. Experienced viewers' ratings were similar to the expert panel's ratings. Content analysis of viewers' reasons for their representational quality ratings corroborated ratings of therapy-specific content. A video that combines and clearly depicts therapy objectives, client improvement, and the effectiveness of music within a therapeutic intervention best represent the music therapy profession in a public social platform like YouTube.

The objective of this study is to investigate reliability and accuracy of the information on YouTube videos related to CPR and BLS in accord with 2010 CPR guidelines. YouTube was queried using four search terms 'CPR', 'cardiopulmonary resuscitation', 'BLS' and 'basic life support' between 2011 and 2013. Sources that uploaded the videos, the record time, the number of viewers in the study period, inclusion of human or manikins were recorded. The videos were rated if they displayed the correct order of resuscitative efforts in full accord with 2010 CPR guidelines or not. Two hundred and nine videos meeting the inclusion criteria after the search in YouTube with four search terms ('CPR', 'cardiopulmonary resuscitation', 'BLS' and 'basic life support') comprised the study sample subjected to the analysis. Median score of the videos is 5 (IQR: 3.5-6). Only 11.5% (n = 24) of the videos were found to be compatible with 2010 CPR guidelines with regard to sequence of interventions. Videos uploaded by 'Guideline bodies' had significantly higher rates of download when compared with the videos uploaded by other sources. Sources of the videos and date of upload (year) were not shown to have any significant effect on the scores received (P = 0.615 and 0.513, respectively). The videos' number of downloads did not differ according to the videos compatible with the guidelines (P = 0.832). The videos downloaded more than 10,000 times had a higher score than the others (P = 0.001). The majority of You-Tube video clips purporting to be about CPR are not relevant educational material. Of those that are focused on teaching CPR, only a small minority optimally meet the 2010 Resucitation Guidelines. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

To identify videos on YouTube concerning advance care planning (ACP) and synthesise existing video content and style elements. Informed by stakeholder engagement, two researchers searched YouTube for ACP videos using predefined search terms and snowballing techniques. Videos identified were reviewed and deemed ineligible for analysis if they: targeted healthcare professionals; contained irrelevant content; focused on viewers under the age of 18; were longer than 7 min in duration; received fewer than 150 views; were in a language other than English; or were a duplicate version. For each video, two investigators independently extracted general information as well as video content and stylistic characteristics. The YouTube search identified 23 100 videos with 213 retrieved for assessment and 42 meeting eligibility criteria. The majority of videos had been posted to YouTube since 2010 and produced by organisations in the USA (71%). Viewership ranged from 171 to 10 642. Most videos used a documentary style and featured healthcare providers (60%) rather than patients (19%) or families (45%). A minority of videos (29%) used upbeat or hopeful music. The videos frequently focused on completing legal medical documents (86%). None of the ACP videos on YouTube went viral and a relatively small number of them contained elements endorsed by stakeholders. In emphasising the completion of legal medical documents, videos may have failed to support more meaningful ACP. Further research is needed to understand the features of videos that will engage patients and the wider community with ACP and palliative and end-of-life care conversations.

The content and quality of medical information available on video sharing websites such as YouTube is not known. We analyzed the source and quality of medical information about Ebola hemorrhagic fever (EHF) disseminated on YouTube and the video characteristics that influence viewer behavior. An inquiry for the search term 'Ebola' was made on YouTube. The first 100 results were arranged in decreasing order of "relevance" using the default YouTube algorithm. Videos 1-50 and 51-100 were allocated to a high relevance (HR), and a low relevance (LR) video group, respectively. Multivariable logistic regression models were used to assess the predictors of a video being included in the HR vs. LR groups. Fourteen videos were excluded because they were parodies, songs or stand-up comedies (n = 11), not in English (n = 2) or a remaining part of a previous video (n = 1). Two scales, the video information and quality and index and the medical information and content index (MICI) assessed the overall quality, and the medical content of the videos, respectively. There were no videos from hospitals or academic medical centers. Videos in the HR group had a higher median number of views (186,705 vs. 43,796, p < 0.001), more 'likes' (1119 vs. 224, p < 0.001), channel subscriptions (208 vs. 32, p < 0.001), and 'shares' (519 vs. 98, p < 0.001). Multivariable logistic regression showed that only the 'clinical symptoms' component of the MICI scale was associated with a higher likelihood of a video being included in the HR vs. LR group.(OR 1.86, 95 % CI 1.06-3.28, p = 0.03). YouTube videos presenting clinical symptoms of infectious diseases during epidemics are more likely to be included in the HR group and influence viewers behavior.

Introduction The amount of information being uploaded onto social video platforms, such as YouTube, Vimeo, and Veoh, continues to spiral, making it increasingly difficult to discern reliable health information from misleading content. There are thousands of YouTube videos promoting misleading information about anorexia (eg, anorexia as a healthy lifestyle). Objective The aim of this study was to investigate anorexia-related misinformation disseminated through YouTube videos. Methods We retrieved YouTube videos related to anorexia using the keywords anorexia, anorexia nervosa, proana, and thinspo on October 10, 2011.Three doctors reviewed 140 videos with approximately 11 hours of video content, classifying them as informative, pro-anorexia, or others. By informative we mean content describing the health consequences of anorexia and advice on how to recover from it; by pro-anorexia we mean videos promoting anorexia as a fashion, a source of beauty, and that share tips and methods for becoming and remaining anorexic. The 40 most-viewed videos (20 informative and 20 pro-anorexia videos) were assessed to gauge viewer behavior. Results The interrater agreement of classification was moderate (Fleiss’ kappa=0.5), with 29.3% (n=41) being rated as pro-anorexia, 55.7% (n=78) as informative, and 15.0% (n=21) as others. Pro-anorexia videos were favored 3 times more than informative videos (odds ratio [OR] 3.3, 95% CI 3.3-3.4, P<.001). Conclusions Pro-anorexia information was identified in 29.3% of anorexia-related videos. Pro-anorexia videos are less common than informative videos; however, in proportional terms, pro-anorexia content is more highly favored and rated by its viewers. Efforts should focus on raising awareness, particularly among teenagers, about the trustworthiness of online information about beauty and healthy lifestyles. Health authorities producing videos to combat anorexia should consider involving celebrities and models to reach a wider audience. More

Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader's activity as a video commentator, and uploader's physical location by country. The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more positive feedback and comments than pro-anorexia videos

Introduction: Many patients conduct internet searches to manage their own health problems, to decide if they need professional help, and to corroborate information given in a clinical encounter. Good information can improve patients’ understanding of their condition and their self-efficacy. Patients with spinal cord injury (SCI) featuring neurogenic bladder (NB) require knowledge and skills related to their condition and need for intermittent catheterization (IC). Methods: Information quality was evaluated in videos accessed via YouTube relating to NB and IC using search terms “neurogenic bladder intermittent catheter” and “spinal cord injury intermittent catheter.” Video content was independently rated by 3 investigators using criteria based on European Urological Association (EAU) guidelines and established clinical practice. Results: In total, 71 videos met the inclusion criteria. Of these, 12 (17%) addressed IC and 50 (70%) contained information on NB. The remaining videos met inclusion criteria, but did not contain information relevant to either IC or NB. Analysis indicated poor overall quality of information, with some videos with information contradictory to EAU guidelines for IC. High-quality videos were randomly distributed by YouTube. IC videos featuring a healthcare narrator scored significantly higher than patient-narrated videos, but not higher than videos with a merchant narrator. About half of the videos contained commercial content. Conclusions: Some good-quality educational videos about NB and IC are available on YouTube, but most are poor. The videos deemed good quality were not prominently ranked by the YouTube search algorithm, consequently user access is less likely. Study limitations include the limit of 50 videos per category and the use of a de novo rating tool. Information quality in videos with healthcare narrators was not higher than in those featuring merchant narrators. Better material is required to improve patients�

The purpose of this study was to assess YouTube videos for their efficacy as a patient resource for infantile spasms. Videos were searched using the terms infantile spasm, spasm, epileptic spasm, and West syndrome. The top 25 videos under each term were selected according to set criteria. Technical quality, diagnosis of infantile spasms, and suitability as a teaching resource were assessed by 2 neurologists using the Medical Video Rating Scale. There were 5858 videos found. Of the 100 top videos, 46% did not meet selection criteria. Mean rating for technical quality was 4.0 of 5 for rater 1 and 3.9 of 5 for rater 2. Raters found 60% and 64% of videos to accurately portray infantile spasms, respectively, with significant agreement (Cohen κ coefficient = 0.75, P < .001). Ten videos were considered excellent examples (grading of 5 of 5) by at least 1 rater. YouTube may be used as an excellent patient resource for infantile spasms if guided search practices are followed.

Celebrity over science? An analysis of Lyme disease video content on YouTube.

Yiannakoulias, N; Tooby, R; Sturrock, S L

2017-10-01

Lyme disease has been a subject of medical controversy for several decades. In this study we looked at the availability and type of content represented in a (n = 700) selection of YouTube videos on the subject of Lyme disease. We classified video content into a small number of content areas, and studied the relationship between these content areas and 1) video views and 2) video likeability. We found very little content uploaded by government or academic institutions; the vast majority of content was uploaded by independent users. The most viewed videos tend to contain celebrity content and personal stories; videos with prevention information tend to be of less interest, and videos with science and medical information tend to be less liked. Our results suggest that important public health information on YouTube is very likely to be ignored unless it is made more appealing to modern consumers of online video content.

PubMed

Hua, My; Yip, Henry; Talbot, Prue

2013-03-01

The objective was to analyse and compare puff and exhalation duration for individuals using electronic nicotine delivery systems (ENDS) and conventional cigarettes in YouTube videos. Video data from YouTube videos were analysed to quantify puff duration and exhalation duration during use of conventional tobacco-containing cigarettes and ENDS. For ENDS, comparisons were also made between 'advertisers' and 'non-advertisers', genders, brands of ENDS, and models of ENDS within one brand. Puff duration (mean =2.4 s) for conventional smokers in YouTube videos (N=9) agreed well with prior publications. Puff duration was significantly longer for ENDS users (mean =4.3 s) (N = 64) than for conventional cigarette users, and puff duration varied significantly among ENDS brands. For ENDS users, puff duration and exhalation duration were not significantly affected by 'advertiser' status, gender or variation in models within a brand. Men outnumbered women by about 5:1, and most users were between 19 and 35 years of age. YouTube videos provide a valuable resource for studying ENDS usage. Longer puff duration may help ENDS users compensate for the apparently poor delivery of nicotine from ENDS. As with conventional cigarette smoking, ENDS users showed a large variation in puff duration (range =1.9-8.3 s). ENDS puff duration should be considered when designing laboratory and clinical trials and in developing a standard protocol for evaluating ENDS performance.

2017-09-01

Conservative treatments are commonly performed therapeutic interventions for the management of carpometacarpal (CMC) joint osteoarthritis (OA). Physical and occupational therapies are starting to use video-based online content as both a patient teaching tool and a source for treatment techniques. YouTube is a popular video-sharing website that can be accessed easily. The purpose of this study was to analyze the quality of content and potential sources of bias in videos available on YouTube pertaining to thumb exercises for CMC OA. The YouTube video database was systematically searched using the search term thumb osteoarthritis and exercises from its inception to March 10, 2017. Authors independently selected videos, conducted quality assessment, and extracted results. A total of 832 videos were found using the keywords. Of these, 10 videos clearly demonstrated therapeutic exercise for the management of CMC OA. In addition, the top-ranked video found by performing a search of "views" was a video with more than 121 863 views uploaded in 2015 that lasted 12.33 minutes and scored only 2 points on the Global Score for Educational Value rating scale. Most of the videos viewed that described conservative interventions for CMC OA management have a low level of evidence to support their use. Although patients and novice hand therapists are using YouTube and other online resources, videos that are produced by expert hand therapists are scarce.

Celiac disease affects about 1% of the population. Since most Polish households have a broadband Internet connection, a lot of people use web resources to learn about health and disease. YouTube service (www.youtube.com) offers a lot of videos concerning celiac disease. However, the credibility of the Polish videos available on YouTube and concerning celiac disease has never been analyzed. The aim of the study was to determine whether the YouTube service offers valuable content for Polish people affected by celiac disease. One hundred and fifty-four unique videos devoted to celiac disease and available in the Polish language were identified and critically assessed. Each video was categorized due to its topic(s), and evaluated for its credibility by two independent researchers. In general, 127 (82.5%) videos were found to be credible. The most credible categories of content presented organizations and events related to celiac disease/celiac society, followed by culinary recipes (100.0, 100.0, and 95.6% of credible videos, respectively). The least trustworthy categories were devoted to pathobiology and advertisements (55.6 and 54.3% of credible videos, respectively). YouTube service can serve as a supplementary source of knowledge for people affected by celiac disease, after careful selection of trustworthy content.

2015-01-01

Background Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. Objective The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. Methods Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader’s activity as a video commentator, and uploader’s physical location by country. Results The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. Conclusions Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more

Interest in marijuana edibles has increased as perceptions of harm from marijuana have decreased. Media and peer influences impact youth substance use, and YouTube is the most popular video-sharing website. No studies have examined the content and accessibility of YouTube videos related to marijuana edibles. To describe the messages conveyed to viewers in YouTube videos about edibles and determine their accessibility to youth. On June 12, 2015, we searched YouTube for videos about marijuana/cannabis/weed edibles. A total of 51 videos were coded for presence of an age restriction, purpose(s) of the videos, consumption of edibles during the video, effects, and safety concerns. Total views across all 51 videos were >9 million. Only 14% (7/51) were restricted to viewers over the age of 18 years. Over half (27/51, 53%) were informative videos, most (20/27, 74%) teaching how to make edibles, and 37% (19/51) were entertaining videos. Someone consumed an edible in 31% (16/51) of the videos, and the type of high was mentioned in 51% (26/51) of the videos, including delayed (18/26, 69%) or intense high (13/26, 50%). Fifty-five percent (28/51) mentioned delta-9-tetrahydrocannabinol potency or dosage. Only 10 of these (36%) presented this information specifically as a warning to prevent adverse effects. Conclusions/Importance: Edibles-related videos are easily found on YouTube, often instructing how to bake your own edibles and lacking information needed for safe consumption, and most are not age-restricted. Videos showing how to make edibles or presenting edibles use in an entertaining way that could influence youth to initiate use.

Abstract Aims To quantify tobacco and alcohol content, including branding, in popular contemporary YouTube music videos; and measure adolescent exposure to such content. Design Ten‐second interval content analysis of alcohol, tobacco or electronic cigarette imagery in all UK Top 40 YouTube music videos during a 12‐week period in 2013/14; on‐line national survey of adolescent viewing of the 32 most popular high‐content videos. Setting Great Britain. Participants A total of 2068 adolescents aged 11–18 years who completed an on‐line survey. Measurements Occurrence of alcohol, tobacco and electronic cigarette use, implied use, paraphernalia or branding in music videos and proportions and estimated numbers of adolescents who had watched sampled videos. Findings Alcohol imagery appeared in 45% [95% confidence interval (CI) = 33–51%] of all videos, tobacco in 22% (95% CI = 13–27%) and electronic cigarettes in 2% (95% CI = 0–4%). Alcohol branding appeared in 7% (95% CI = 2–11%) of videos, tobacco branding in 4% (95% CI = 0–7%) and electronic cigarettes in 1% (95% CI = 0–3%). The most frequently observed alcohol, tobacco and electronic cigarette brands were, respectively, Absolut Tune, Marlboro and E‐Lites. At least one of the 32 most popular music videos containing alcohol or tobacco content had been seen by 81% (95% CI = 79%, 83%) of adolescents surveyed, and of these 87% (95% CI = 85%, 89%) had re‐watched at least one video. The average number of videos seen was 7.1 (95% CI = 6.8, 7.4). Girls were more likely to watch and also re‐watch the videos than boys, P < 0.001. Conclusions Popular YouTube music videos watched by a large number of British adolescents, particularly girls, include significant tobacco and alcohol content, including branding. PMID:25516167

Bueno, Mariana; Nishi, Érika Tihemi; Costa, Taine; Freire, Laís Machado; Harrison, Denise

Objective of this study was to conduct a systematic review of YouTube videos showing neonatal blood sampling, and to evaluate pain management and comforting interventions used. Selected videos were consumer- or professional-produced videos showing human newborns undergoing heel lancing or venipuncture for blood sampling, videos showing the entire blood sampling procedure (from the first attempt or puncture to the time of application of a cotton ball or bandage), publication date prior to October 2014, Portuguese titles, available audio. Search terms included "neonate," "newborn," "neonatal screening," and "blood collection." Two reviewers independently screened the videos and extracted the following data. A total of 13 140 videos were retrieved, of which 1354 were further evaluated, and 68 were included. Videos were mostly consumer produced (97%). Heel lancing was performed in 62 (91%). Forty-nine infants (72%) were held by an adult during the procedure. Median pain score immediately after puncture was 4 (interquartile range [IQR] = 0-5), and median length of cry throughout the procedure was 61 seconds (IQR = 88). Breastfeeding (3%) and swaddling (1.5%) were rarely implemented. Posted YouTube videos in Portuguese of newborns undergoing blood collection demonstrate minimal use of pain treatment, and maximal distress during procedures. Knowledge translation strategies are needed to implement effective measures for neonatal pain relief and comfort.

Medical education videos can enhance learning and easily integrate into common instructional methods. YouTube permits worldwide access to high-quality medical education videos; however, no studies have described the reach of medical education videos on YouTube or what topics are preferred. One year of YouTube analytics data (February 1, 2016, to January 31, 2017) was collected for a medical education-focused channel called Osmosis. Created December 20, 2015, the channel had 189 disease-focused videos by January 2017. Viewer and subscriber data were analyzed according to the World Bank's 4 income and 7 region classifications. Topic viewing was analyzed according to income level. The channel had accumulated 105,117 subscribers and 5,226,405 views for 20,153,093 minutes (38.3 years) from viewers located in 213/218 (97.7%) World Bank economies. While the number of videos increased 4.8 fold from February 2016 to January 2017, monthly views increased 50 fold and subscribers increased 117 fold. Low or middle income countries generated 2.2 million (42%) views and 53,000 (50%) subscribers, with similar view proportions across income level during the 12 months. A plurality of views (1.5 million, 29%) came from North America; Sub-Saharan Africa had the lowest number (150,000, 2.9%). Topic viewing generally corresponded to population health statistics. Medical education content on YouTube can immediately and consistently reach a global viewership with relevant content. Educators may consider posting videos to YouTube to reach a broad audience. Future work should seek to optimize assessment of learning and investigate how videos may affect patients.

Medical educators and patients are turning to YouTube to teach and learn about medical conditions. These videos are from authors whose credibility cannot be verified & are not peer reviewed. As a result, studies that have analyzed the educational content of YouTube have reported dismal results. These studies have been unable to exclude videos created by questionable sources and for non-educational purposes. We hypothesize that medical education YouTube videos, authored by credible sources, are of high educational value and appropriately suited to educate the public. Credible videos about cardiovascular diseases were identified using the Mayo Clinic's Center for Social Media Health network. Content in each video was assessed by the presence/absence of 7 factors. Each video was also evaluated for understandability using the Suitability Assessment of Materials (SAM). User engagement measurements were obtained for each video. A total of 607 videos (35 hours) were analyzed. Half of all videos contained 3 educational factors: treatment, screening, or prevention. There was no difference between the number of educational factors present & any user engagement measurement (p NS). SAM scores were higher in videos whose content discussed more educational factors (p<0.0001). However, none of the user engagement measurements correlated with higher SAM scores. Videos with greater educational content are more suitable for patient education but unable to engage users more than lower quality videos. It is unclear if the notion “content is king” applies to medical videos authored by credible organizations for the purposes of patient education on YouTube. PMID:24367517

As a communications strategy, education entertainment has been used to inform, influence, and shift societal and individual behaviors. Recently, there has been an increasing number of entertainment-education YouTube videos focused on hand hygiene. However, there is currently no understanding about the quality of these videos; therefore, this study aimed to explore the social media content and user engagement with these videos. The search terms "hand hygiene" and "hand hygiene education" were used to query YouTube. Video content had to be directed at a health care professional audience. Using author designed checklists, each video was systematically evaluated and grouped according to educational usefulness and was subsequently evaluated against the categories of attractiveness, comprehension, and persuasiveness. A total of 400 videos were screened, with 70 videos retained for analysis. Of these, 55.7% (n = 39) were categorized as educationally useful. Overall, educationally useful videos scored higher than noneducationally useful videos across the categories of attractiveness, comprehension, and persuasiveness. Miscommunication of the concept of My 5 Moments for Hand Hygiene was observed in several of the YouTube videos. The availability of educationally useful videos in relation to hand hygiene is evident; however, it is clear that there are opportunities for contributors using this medium to strengthen their alignment with social media best practice principles to maximize the effectiveness, reach, and sustainability of their content.

The aims of this study were to determine the following: first, are there educationally useful videos of parents of children with autism sharing their experiences? Second, do any of the data related to videos help in identifying useful videos? And third, what do posted comments tell us? YouTube was searched for videos of parents sharing their experiences. The following parameters were collected: title, creator, URL, duration, number of viewers, likes, dislikes, comments, days on YouTube, and country. Based on agreed-upon criteria, videos were divided independently into educationally useful and non-useful categories. A critical thematic analysis of comments was conducted. A total of 180 videos were finally identified, of which 106 (59%) provided useful information, scoring 15.3 ± 0.7 (mean ± SD); 74 (41%) were determined to be not educationally useful, scoring 8.6 ± 2.1. The differences in scores were significant (p < 0.001), but there were no significant differences between the useful and non-useful groups in terms of video parameters. No correlation was found between scores and any of the videos' parameters. In conclusion, there are videos that can be used as educational resources. The videos' parameters did not differentiate between useful and non useful. Useful videos were mostly created by professional societies and by parents. The study reflects the emerging role of YouTube in sharing experiences.

Active Galactic Videos is an astronomy-focused YouTube channel run by a team at the University of Arizona. The channel both produces astronomy-focused educational content for public audiences and opens a window into the world of professional astronomy by showcasing the work done at Steward Observatory and in Southern Arizona. The channel is mainly run by undergraduate students from a variety of backgrounds including: astronomy, education, film, music, english, and writing. In addition to providing educational content for public audiences, this project provides opportunities for undergraduate students to learn about astronomy content, general astronomy pedagogy, as well as science communication. This is done through developing the practical skills needed to take on the challenge of creating effective and engaging videos. Students write, film, score, direct, and edit each video while conscious of how each piece can affect the teaching/storytelling of the concept at hand. The team has produced various styles of video: presentational, interviews, musical/poetic, tours, and documentaries. In addition to YouTube, the Active Galactic Videos team maintains a social media presence on Facebook, Twitter, and Instagram. These help to widely distribute the content as well as to publicize the main Youtube channel. In addition to providing an overview of our educational work, we present 51 videos, or two year's, worth of online analytics that we are using to better understand our audience, to examine what videos have been popular and successful, and how people are accessing our content. We will present our experience in order to help others learn about improving astronomy education online, as well as astronomy communication and outreach in general.We acknowledge the Howard Hughes Medical Institute for grant support of this and related education initiatives

To assess the quality of the content of YouTube videos for cataract surgery patient education. Hotel Dieu Hospital, Kingston, Ontario, Canada. Observational study. "Cataract surgery," "cataract surgery for patients," and "cataract surgery patient education" were used as search terms. The first two pages of search results were reviewed. Descriptive statistics such as video length and view count were obtained. Two cataract surgeons devised 14 criteria important for educating patients about the procedure. Videos were analyzed based on the presence or absence of these criteria. Videos were also assessed for whether they had a primary commercial intent. Seventy-two videos were analyzed after excluding 48 videos that were duplicate, irrelevant, or not in English. The majority of videos came from a medical professional (71%) and many depicted a real cataract surgery procedure (43%). Twenty-one percent of the videos had a primary commercial intent to promote a practice or product. Out of a total possible 14 points, the mean number of usefulness criteria satisfied was only 2.28 ± 1.80. There was no significant difference in view count between the most useful videos and other videos (p = 0.94). Videos from medical organizations such as the National Health Service were more useful (p < 0.0001). Cataract surgery videos are popular on YouTube, but most are not adequately educational. Patients may be receiving biased information from videos created with primary commercial intent. Physicians should be aware of the type of information patients may be accessing on YouTube.

Rates of anal squamous cell carcinoma have increased over recent decades. The aim of this study was to describe characteristics of widely viewed YouTube videos about anal cancer. A total of 57 videos were identified and reviewed. Videos were assessed and coded with respect to date uploaded, upload source, gender of presenter, number of views, length in minutes, number of likes and dislikes, and selected aspects of content. Each video was assessed to determine if the sole purpose of the video was to provide information regarding anal cancer or existed to serve another purpose. Content related to anal cancer was categorized. The mean number of views was 23,548 (range 1014-440,078), and the average length of videos was 8:14 min. The upload source of 57 videos was 19 (33.3%) by consumers, 12 (21.1%) by professional, and 26 (45.6%) by news-based sources. More than half ( n = 30; 52.6%) had the sole purpose of providing information. The most frequently mentioned topics were treatment ( n = 25, 43.9%), symptoms ( n = 15, 26.3%), encouraging screening, human papillomavirus, and pain, respectively ( n = 14, 26.4% for each); only 6 of the 57 videos (10.5%) specifically mentioned prevention. None of 57 most widely viewed videos were uploaded by any agency of the U.S. Public Health Service or by any other U.S. governmental agency. It is important for health practitioners to be aware of the type of information available for their patients on the YouTube platform.

2017-01-01

YouTube ( www.youtube.com ) is the most popular video-sharing Web site on the Internet and is used by medical students as a source of information regarding mental health conditions, including schizophrenia. The accuracy and educational utility of schizophrenia presentations on YouTube are unknown. The purpose of this study was to analyze the accuracy of depictions of psychosis in the context of a diagnosis of schizophrenia (referred to in this article as "acute schizophrenia") on YouTube and to assess the utility of these videos as educational tools for teaching medical students to recognize the clinical features of acute schizophrenia. YouTube was searched for videos purporting to show acute schizophrenia. Eligible videos were independently rated by two consultant psychiatrists on two separate occasions 22 days apart for diagnostic accuracy, psychopathology, and educational utility. Videos (N=4,200) were assessed against predefined inclusion and exclusion criteria. The majority were not eligible for further analysis, mostly because they did not claim to show a patient with schizophrenia (74%) or contained duplicated content (11%). Of 35 videos that met the eligibility and adequacy criteria, only 12 accurately depicted acute schizophrenia. Accurate videos were characterized by persecutory delusions (83%), inappropriate affect (75%), and negative symptoms (83%). Despite the fact that 83% of accurate videos were deemed to have good educational utility compared with 15% of inaccurate videos, accurate and inaccurate videos had similar view counts (290,048 versus 186,124). Schizophrenia presentations on YouTube offer a distorted picture of the condition.

Are YouTube seizure videos misleading? Neurologists do not always agree.

2013-11-01

The internet has become the first stop for the public and patients to seek health-related information. Video-sharing websites are particularly important sources of information for those seeking answers about seizures and epilepsy. Because of the widespread popularity of YouTube, we sought to explore whether a seizure diagnosis and classification could reliably be applied. All videos related to "seizures" were reviewed, and irrelevant videos were excluded. The remaining 162 nonduplicate videos were analyzed by 4 independent pediatric neurologists who classified the events as epilepsy seizures, nonepileptic seizures, or indeterminate. Videos designated as epilepsy seizures were then classified into focal, generalized, or unclassified. At least 3 of the 4 reviewers agreed that 35% of the videos showed that the events were "epilepsy seizures", at least 3 of the 4 reviewers agreed that 28% of the videos demonstrated that the events were "nonepileptic seizures", and there was good agreement that 7% of the videos showed that the event was "indeterminate". Overall, interrater agreement was moderate at k=0.57 for epilepsy seizures and k=0.43 for nonepileptic seizures. For seizure classification, reviewer agreement was greatest for "generalized seizures" (k=0.45) and intermediate for "focal seizures" (k=0.27), and there was no agreement for unclassified events (k=0.026, p=0.2). Overall, neurology reviewer agreement suggests that only approximately one-third of the videos designated as "seizures" on the most popular video-sharing website, YouTube, definitely depict a seizure. Caution should be exercised in the use of such online video media for accessing educational or self-diagnosis aids for seizures. © 2013.

The purpose of this study was to explore the types of social support messages YouTube users posted on medical videos. Specifically, the study compared messages posted on inflammatory bowel disease-related videos and ostomy-related videos. Additionally, the study analyzed the differences in social support messages posted on lay-created videos and professionally-created videos. Conducting a content analysis, the researchers unitized the comments on each video; the total number of thought units amounted to 5,960. Researchers coded each thought unit through the use of a coding scheme modified from a previous study. YouTube users posted informational support messages most frequently (65.1%), followed by emotional support messages (18.3%), and finally, instrumental support messages (8.2%).

This study aimed to evaluate the accuracy of Korean videos regarding Parkinson's disease (PD) on YouTube and viewers' responses to them. YouTube search was performed using the search term "Parkinson disease" in Korean language on March 28, 2017. Two independent neurologists categorized the videos into "reliable", "misleading" or "patient experiences". The number of views, days since upload, video length, number of "likes" and "dislikes", and upload source were collected for each video. A total of 138 videos were included in this study. Of these, 91 videos (65.9%) were reliable; 31 (22.5%) were misleading, and 16 (11.6%) were of patient experiences. The videos with patient experiences had the highest number of mean views with 9710.4±3686.9, followed by misleading videos with 5075.0±1198.6, and reliable videos with 2146.8±353.4 (ANOVA, p<0.001). The number of mean views per day was 4.0±0.6 for the reliable videos, which was significantly lower than the misleading videos (9.7±3.4, p=0.020) and the videos of patient experiences (11.3±4.6, p=0.023). The reliable videos were mostly uploaded by university hospitals (46.2%) and misleading videos by health-related commercial entities (74.2%). The misleading videos as well as the videos of patient experiences advocated "diet" asa treatment of PD. The current study found that only two-thirds of the Korean videos regarding PD on YouTube provide reliable information. More importantly, the videos with reliable contents were less popular than videos with misleading contents. Further efforts are warranted to effectively increase the dissemination of accurate and scientifically proven PD information to YouTube users. Copyright © 2017 Elsevier Ltd. All rights reserved.

A number of studies have evaluated the educational contents of videos on YouTube. However, little analysis has been done on videos about physical examination. This study aimed to analyze YouTube videos about physical examination of the cardiovascular and respiratory systems. It was hypothesized that the educational standards of videos on YouTube would vary significantly. During the period from November 2, 2011 to December 2, 2011, YouTube was searched by three assessors for videos covering the clinical examination of the cardiovascular and respiratory systems. For each video, the following information was collected: title, authors, duration, number of viewers, and total number of days on YouTube. Using criteria comprising content, technical authority, and pedagogy parameters, videos were rated independently by three assessors and grouped into educationally useful and non-useful videos. A total of 1920 videos were screened. Only relevant videos covering the examination of adults in the English language were identified (n=56). Of these, 20 were found to be relevant to cardiovascular examinations and 36 to respiratory examinations. Further analysis revealed that 9 provided useful information on cardiovascular examinations and 7 on respiratory examinations: scoring mean 14.9 (SD 0.33) and mean 15.0 (SD 0.00), respectively. The other videos, 11 covering cardiovascular and 29 on respiratory examinations, were not useful educationally, scoring mean 11.1 (SD 1.08) and mean 11.2 (SD 1.29), respectively. The differences between these two categories were significant (P<.001 for both body systems). The concordance between the assessors on applying the criteria was 0.89, with a kappa score >.86. A small number of videos about physical examination of the cardiovascular and respiratory systems were identified as educationally useful; these videos can be used by medical students for independent learning and by clinical teachers as learning resources.

Objective YouTube is now the second most visited site on the Internet. We aimed to compare characteristics of and messages conveyed by cigarette- and hookah-related videos on YouTube. Methods Systematic search procedures yielded 66 cigarette-related and 61 hookah-related videos. After 3 trained qualitative researchers used an iterative approach to develop and refine definitions for the coding of variables, 2 of them independently coded each video for content including positive and negative associations with smoking and major content type. Results Median view counts were 606,884 for cigarettes and 102,307 for hookahs (P<.001). However, the number of comments per 1,000 views was significantly lower for cigarette-related videos than for hookah-related videos (1.6 vs 2.5, P=.003). There was no significant difference in the number of “like” designations per 100 reactions (91 vs. 87, P=.39). Cigarette-related videos were less likely than hookah-related videos to portray tobacco use in a positive light (24% vs. 92%, P<.001). In addition, cigarette-related videos were more likely to be of high production quality (42% vs. 5%, P<.001), to mention short-term consequences (50% vs. 18%, P<.001) and long-term consequences (44% vs. 2%, P<.001) of tobacco use, to contain explicit antismoking messages (39% vs. 0%, P<.001), and to provide specific information on how to quit tobacco use (21% vs. 0%, P<.001). Conclusions Although Internet user–generated videos related to cigarette smoking often acknowledge harmful consequences and provide explicit antismoking messages, hookah-related videos do not. It may be valuable for public health programs to correct common misconceptions regarding hookah use. PMID:22363069

ABSTRACT Background: The suspension of compulsory scheduling of some pediatric vaccines has been discussed for a long time by health authorities in Italy but the current decrease of vaccination rates is a matter of concern. YouTube is the most popular video-based social media website. Considering the demonstrated impact of internet on vaccination decision-making and the increasing use of social media to share and disseminate health information, the aim of this study was to explore the message available on YouTube videos about vaccination. Methods: An observational study was conducted searching for YouTube videos in September 2015 and updated in January 2016, by using the keyword “vaccinations.” We included recently posted videos in Italian on child vaccination (2014–2015). Videos were classified according to the message tone. Results: A total of 123 videos were selected. Pro-vaccination videos were 62 (50%), anti-vaccination 28 (23%), neutral or without a clear position in favor or against vaccination 33 (27%). Focusing on the first 2 groups, pro-vaccination videos had a higher number of views compared with those unfavorable (1602 ± 6544 vs 1482 ± 2735) (p < 0.001). However, anti-vaccination videos were liked more by viewers (17.8 ± 31.3) than positive ones (13.2 ± 44.7) (p < 0.001) in addition to being more shared (23 ± 22.6 vs 3.8 ± 5.5, p < 0.001). Conclusions: Most of the videos were positive in tone, but those that disapproved of immunization were the most liked and shared. Considering the growing number of viewers, it is important to monitor the web to understand audience characteristics and what influences public opinions to use communication strategies more effectively.

Background Interest in marijuana edibles has increased as perceptions of harm from marijuana have decreased. Media and peer influences impact youth substance use, and YouTube is the most popular video-sharing website. No studies have examined the content and accessibility of YouTube videos related to marijuana edibles. Objectives To describe the messages conveyed to viewers in YouTube videos about edibles and determine their accessibility to youth. Methods On June 12, 2015, we searched YouTube for videos about marijuana/cannabis/weed edibles. A total of 51 videos were coded for presence of an age restriction, purpose(s) of the videos, consumption of edibles during the video, effects, and safety concerns. Results Total views across all 51 videos were >9 million. Only 14% (7/51) were restricted to viewers over the age of 18 years. Over half (27/51, 53%) were informative videos, most (20/27, 74%) teaching how to make edibles, and 37% (19/51) were entertaining videos. Someone consumed an edible in 31% (16/51) of the videos, and the type of high was mentioned in 51% (26/51) of the videos, including delayed (18/26, 69%) or intense high (13/26, 50%). Fifty-five percent (28/51) mentioned delta-9-tetrahydrocannabinol potency or dosage. Only 10 of these (36%) presented this information specifically as a warning to prevent adverse effects. Conclusions/Importance Edibles-related videos are easily found on YouTube, often instructing how to bake your own edibles and lacking information needed for safe consumption, and most are not age-restricted. Videos showing how to make edibles or presenting edibles use in an entertaining way that could influence youth to initiate use. PMID:28145799

Background. YouTube is an increasingly important medium for consumer health information - with content provided by healthcare professionals, government and non-government organizations, industry, and consumers themselves. It is a rapidly developing area of study for healthcare researchers. We examine the methods used in reviews of YouTube consumer health videos to identify trends and best practices. Methods and Materials. Published reviews of consumer-oriented health-related YouTube videos were identified through PubMed. Data extracted from these studies included type of journal, topic, characteristics of the search, methods of review including number of reviewers and method to achieve consensus between reviewers, inclusion and exclusion criteria, characteristics of the videos reported, ethical oversight, and follow-up. Results. Thirty-three studies were identified. Most were recent and published in specialty journals. Typically, these included more than 100 videos, and were examined by multiple reviewers. Most studies described characteristics of the videos, number of views, and sometime characteristics of the viewers. Accuracy of portrayal of the health issue under consideration was a common focus. Conclusion. Optimal transparency and reproducibility of studies of YouTube health-related videos can be achieved by following guidance designed for systematic review reporting, with attention to several elements specific to the video medium. Particularly when seeking to replicate consumer viewing behavior, investigators should consider the method used to select search terms, and use a snowballing rather than a sequential screening approach. Discontinuation protocols for online screening of relevance ranked search results is an area identified for further development.

To investigate the integrity with which parents and carers implement PECS in naturalistic settings, utilizing a sample of videos obtained from YouTube. Twenty-one YouTube videos meeting selection criteria were identified. The videos were reviewed for instances of seven implementer errors and, where appropriate, presence of a physical prompter. Forty-three per cent of videos and 61% of PECS exchanges contained errors in parent implementation of specific teaching strategies of the PECS training protocol. Vocal prompts, incorrect error correction and the absence of timely reinforcement occurred most frequently, while gestural prompts, insistence on speech, incorrect use of the open hand prompt and not waiting for the learner to initiate occurred less frequently. Results suggest that parents engage in vocal prompting and incorrect use of the 4-step error correction strategy when using PECS with their children, errors likely to result in prompt dependence.

YouTube as a platform for publishing clinical skills training videos.

The means to share educational materials have grown considerably over the years, especially with the multitude of Internet channels available to educators. This article describes an innovative use of YouTube as a publishing platform for clinical educational materials.The authors posted online a series of short videos for teaching clinical procedures anticipating that they would be widely used. The project Web site attracted little traffic, alternatives were considered, and YouTube was selected for exploration as a publication channel. YouTube's analytics tools were used to assess uptake, and viewer comments were reviewed for specific feedback in support of evaluating and improving the materials posted.The uptake was much increased with 1.75 million views logged in the first 33 months. Viewer feedback, although limited, proved useful. In addition to improving uptake, this approach also relinquishes control over how materials are presented and how the analytics are generated. Open and anonymous access also limits relationships with end users.In summary, YouTube was found to provide many advantages over self-publication, particularly in terms of technical simplification, increased audience, discoverability, and analytics. In contrast to the transitory interest seen in most YouTube content, the channel has seen sustained popularity. YouTube's broadcast model diffused aspects of the relationship between educators and their learners, thereby limiting its use for more focused activities, such as continuing medical education.

Cultural values and cross-cultural video consumption on YouTube

PubMed Central

Macy, Michael

2017-01-01

Video-sharing social media like YouTube provide access to diverse cultural products from all over the world, making it possible to test theories that the Web facilitates global cultural convergence. Drawing on a daily listing of YouTube’s most popular videos across 58 countries, we investigate the consumption of popular videos in countries that differ in cultural values, language, gross domestic product, and Internet penetration rate. Although online social media facilitate global access to cultural products, we find this technological capability does not result in universal cultural convergence. Instead, consumption of popular videos in culturally different countries appears to be constrained by cultural values. Cross-cultural convergence is more advanced in cosmopolitan countries with cultural values that favor individualism and power inequality. PMID:28531228

To assess the content of currently available YouTube videos seeking to educate patients regarding commonly performed imaging examinations. After initial testing of possible search terms, the first two pages of YouTube search results for "CT scan," "MRI," "ultrasound patient," "PET scan," and "mammogram" were reviewed to identify educational patient videos created by health organizations. Sixty-three included videos were viewed and assessed for a range of features. Average views per video were highest for MRI (293,362) and mammography (151,664). Twenty-seven percent of videos used a nontraditional format (eg, animation, song, humor). All videos (100.0%) depicted a patient undergoing the examination, 84.1% a technologist, and 20.6% a radiologist; 69.8% mentioned examination lengths, 65.1% potential pain/discomfort, 41.3% potential radiation, 36.5% a radiology report/results, 27.0% the radiologist's role in interpretation, and 13.3% laboratory work. For CT, 68.8% mentioned intravenous contrast and 37.5% mentioned contrast safety. For MRI, 93.8% mentioned claustrophobia, 87.5% noise, 75.0% need to sit still, 68.8% metal safety, 50.0% intravenous contrast, and 0.0% contrast safety. For ultrasound, 85.7% mentioned use of gel. For PET, 92.3% mentioned radiotracer injection, 61.5% fasting, and 46.2% diabetic precautions. For mammography, unrobing, avoiding deodorant, and possible additional images were all mentioned by 63.6%; dense breasts were mentioned by 0.0%. Educational patient videos on YouTube regarding common imaging examinations received high public interest and may provide a valuable patient resource. Videos most consistently provided information detailing the examination experience and less consistently provided safety information or described the presence and role of the radiologist.

To examine the information about tinnitus contained in different video sources on YouTube. The 100 most widely viewed tinnitus videos were manually coded. Firstly, we identified the sources of upload: consumer, professional, television-based clip, and internet-based clip. Secondly, the videos were analyzed to ascertain what pertinent information they contained from a current National Institute on Deafness and Other Communication Disorders fact sheet. Of the videos, 42 were consumer-generated, 33 from media, and 25 from professionals. Collectively, the 100 videos were viewed almost 9 million times. The odds of mentioning "objective tinnitus" in professional videos were 9.58 times those from media sources [odds ratio (OR) = 9.58; 95% confidence interval (CI): 1.94, 47.42; P = 0.01], whereas these odds in consumer videos were 51% of media-generated videos (OR = 0.51; 95% CI: 0.20, 1.29; P = 0.16). The odds that the purpose of a video was to sell a product or service were nearly the same for both consumer and professional videos. Consumer videos were found to be 4.33 times as likely to carry a theme about an individual's own experience with tinnitus (OR = 4.33; 95% CI: 1.62, 11.63; P = 0.004) as media videos. Of the top 100 viewed videos on tinnitus, most were uploaded by consumers, sharing individuals' experiences. Actions are needed to make scientific medical information more prominently available and accessible on YouTube and other social media.

YouTube (http://youtube.com) is a free video sharing website that allows users to post and view videos. Although there are definite limitations in the applicability of this website to telerehabilitation, the YouTube technology offers potential uses that should not be overlooked. For example, some types of therapy, such as errorless learning therapy for certain language and cognitive deficits can be provided remotely via YouTube. In addition, the website’s social networking capabilities, via the asynchronous posting of comments and videos in response to posted videos, enables individuals to gain valuable emotional support by communicating with others with similar health and rehabilitation challenges. This article addresses the benefits and limitations of YouTube in the context of telerehabilitation and reports patient feedback on errorless learning therapy for aphasia delivered via videos posted on YouTube.

2018-04-16

A quality-control YouTube-based study using the recognized quality scoring systems. In this study, our aim was to confirm the accuracy and quality of the information in kyphosis videos shared on YouTube. The Internet is a widely and increasingly used source for obtaining medical information both by patients and clinicians. YouTube, in particular, manifests itself as a leading source with its ease of access to information and visual advantage for Internet users. The first 50 videos returned by the YouTube search engine in response to 'kyphosis' keyword query were included in the study and categorized under seven and six groups, based on their source and content. The popularity of the videos were evaluated with a new index called the video power index (VPI). The quality, educational quality and accuracy of the source of information were measured using the JAMA score, Global Quality Score (GQS) and Kyphosis Specific Score (KSS). Videos had a mean duration of 397 seconds and a mean number of views of 131,644, with a total viewing number of 6,582,221. The source (uploader) in 36% of the videos was a trainer and the content in 46% of the videos was exercise training. 72% of the videos were about postural kyphosis. Videos had a mean JAMA score of 1.36 (range: 1 to 4), GQS of 1.68 (range: 1 to 5) and KSS of 3.02 (range:0 to 32). The academic group had the highest scores and the lowest VPIs. Online information on kyphosis is low quality and its contents are of unknown source and accuracy. In order to keep the balance in sharing the right information with the patient, clinicians should possess knowledge about the online information related to their field, and should contribute to the development of optimal medical videos. 3.

Parents sometimes show young children YouTube videos on their smartphones. We studied the interaction of 55 Indian children born between December 2014 and May 2015 who watched YouTube videos when they were 6-24 months old. The children were recruited by the researchers using professional and personal contacts and visited by the same two observers at four ages, for at least 10 minutes. The observers recorded the children's abilities to interact with touch screens and identify people in videos and noted what videos attracted them the most. The children were attracted to music at six months of age and were interested in watching the videos at 12 months. They could identify their parents in videos at 12 months and themselves by 24 months. They started touching the screen at 18 months and could press the buttons that appeared on the screen, but did not understand their use. The children preferred watching dance performances by multiple artists with melodical music, advertisements for products they used and videos showing toys and balloons. Children up to two years of age could be entertained and kept busy by showing them YouTube clips on smartphones, but did not learn anything from the videos. ©2018 Foundation Acta Paediatrica.

Focusing on several message features that are prominent in antismoking campaign literature, this content-analytic study examines 934 antismoking video clips on YouTube for the following characteristics: message sensation value (MSV) and three types of message appeal (threat, social and humor). These four characteristics are then linked to YouTube's interactive audience response mechanisms (number of viewers, viewer ratings and number of comments) to capture message reach, viewer preference and viewer engagement. The findings suggest the following: (i) antismoking messages are prevalent on YouTube, (ii) MSV levels of online antismoking videos are relatively low compared with MSV levels of televised antismoking messages, (iii) threat appeals are the videos' predominant message strategy and (iv) message characteristics are related to viewer reach and viewer preference.

Health consumers are increasingly using the Internet to search for health information. The existence of overloaded, inaccurate, obsolete, or simply incorrect health information available on the Internet is a serious obstacle for finding relevant and good-quality data that actually helps patients. Search engines of multimedia Internet platforms are thought to help users to find relevant information according to their search. But, is the information recovered by those search engines from quality sources? Is the health information uploaded from reliable sources, such as hospitals and health organizations, easily available to patients? The availability of videos is directly related to the ranking position in YouTube search. The higher the ranking of the information is, the more accessible it is. The aim of this study is to analyze the ranking evolution of diabetes health videos on YouTube in order to discover how videos from reliable channels, such as hospitals and health organizations, are evolving in the ranking. The analysis was done by tracking the ranking of 2372 videos on a daily basis during a 30-day period using 20 diabetes-related queries. Our conclusions are that the current YouTube algorithm favors the presence of reliable videos in upper rank positions in diabetes-related searches.

Zika Virus on YouTube: An Analysis of English-language Video Content by Source

PubMed Central

2017-01-01

Objectives The purpose of this study was to describe the source, length, number of views, and content of the most widely viewed Zika virus (ZIKV)-related YouTube videos. We hypothesized that ZIKV-related videos uploaded by different sources contained different content. Methods The 100 most viewed English ZIKV-related videos were manually coded and analyzed statistically. Results Among the 100 videos, there were 43 consumer-generated videos, 38 Internet-based news videos, 15 TV-based news videos, and 4 professional videos. Internet news sources captured over two-thirds of the total of 8 894 505 views. Compared with consumer-generated videos, Internet-based news videos were more likely to mention the impact of ZIKV on babies (odds ratio [OR], 6.25; 95% confidence interval [CI], 1.64 to 23.76), the number of cases in Latin America (OR, 5.63; 95% CI, 1.47 to 21.52); and ZIKV in Africa (OR, 2.56; 95% CI, 1.04 to 6.31). Compared with consumer-generated videos, TV-based news videos were more likely to express anxiety or fear of catching ZIKV (OR, 6.67; 95% CI, 1.36 to 32.70); to highlight fear of ZIKV among members of the public (OR, 7.45; 95% CI, 1.20 to 46.16); and to discuss avoiding pregnancy (OR, 3.88; 95% CI, 1.13 to 13.25). Conclusions Public health agencies should establish a larger presence on YouTube to reach more people with evidence-based information about ZIKV. PMID:28372356

In this study, the reliability of trauma management scenario videos (in English) on YouTube and their compliance with Advanced Trauma Life Support (ATLS ® ) guidelines were investigated. The search was conducted on February 15, 2016 by using the terms "assessment of trauma" and ''management of trauma''. All videos that were uploaded between January 2011 and June 2016 were viewed by two experienced emergency physicians. The data regarding the date of upload, the type of the uploader, duration of the video and view counts were recorded. The videos were categorized according to the video source and scores. The search results yielded 880 videos. Eight hundred and thirteen videos were excluded by the researchers. The distribution of videos by years was found to be balanced. The scores of videos uploaded by an institution were determined to be higher compared to other groups (p = 0.003). The findings of this study display that trauma management videos on YouTube in the majority of cases are not reliable/compliant with ATLS-guidelines and can therefore not be recommended for educational purposes. These data may only be used in public education after making necessary arrangements.

The reach of Spanish-language YouTube videos on physical examinations made by undergraduate medical students

2017-01-01

This study was conducted to evaluate the performance and reach of YouTube videos on physical examinations made by Spanish university students. We analyzed performance metrics for 4 videos on physical examinations in Spanish that were created by medical students at Miguel Hernández University (Elche, Spain) and are available on YouTube, on the following topics: the head and neck (7:30), the cardiovascular system (7:38), the respiratory system (13:54), and the abdomen (11:10). We used the Analytics application offered by the YouTube platform to analyze the reach of the videos from the upload date (February 17, 2015) to July 28, 2017 (2 years, 5 months, and 11 days). The total number of views, length of watch-time, and the mean view duration for the 4 videos were, respectively: 164,403 views (mean, 41,101 views; range, 12,389 to 94,573 views), 425,888 minutes (mean, 106,472 minutes; range, 37,889 to 172,840 minutes), and 2:56 minutes (range, 1:49 to 4:03 minutes). Mexico was the most frequent playback location, followed by Spain, Colombia, and Venezuela. Uruguay, Ecuador, Mexico, and Puerto Rico had the most views per 100,000 population. Spanish-language tutorials are an alternative tool for teaching physical examination skills to students whose first language is not English. The videos were especially popular in Uruguay, Ecuador, and Mexico. PMID:29278903

YouTube, reaches upwards of six billion users on a monthly basis and is a unique source of information distribution and communication. Although the influence of YouTube on personal health decision-making is well established, this study assessed the type of content and viewership on a broad scope of dermatology related content on YouTube. Select terms (i.e. dermatology, sun protection, skin cancer, skin cancer awareness, and skin conditions) were searched on YouTube. Overall, the results included 100 videos with over 47 million viewers. Advocacy was the most prevalent content type at 24% of the total search results. These 100 videos were "shared" a total of 101,173 times and have driven 6,325 subscriptions to distinct YouTube user pages. Of the total videos, 35% were uploaded by or featured an MD/DO/PhD in dermatology or other specialty/field, 2% FNP/PA, 1% RN, and 62% other. As one of the most trafficked global sites on the Internet, YouTube is a valuable resource for dermatologists, physicians in other specialties, and the general public to share their dermatology-related content and gain subscribers. However, challenges of accessing and determining evidence-based data remain an issue.

The Choking Game on YouTube: An Update.

PubMed

Defenderfer, Ellen K; Austin, Jillian E; Davies, W Hobart

2016-01-01

The choking game (TCG) is an adolescent activity in which asphyxiation is used to obtain a "high," occasionally resulting in seizures or death. A plethora of TCG information is available through YouTube, though this content has not been evaluated recently. The current study described TCG as portrayed in YouTube videos and compared views and ratings of TCG videos to unrelated videos. The TCG videos demonstrated diverse methods of asphyxiation, with a minority showing injury to the participants. TCG videos were less likely to be commented on or rated positively than non-choking game videos. TCG prevention videos differed significantly from actual TCG videos in the way they depicted the social context of TCG. Thus, TCG videos are accessible through YouTube, but the prevention materials available on YouTube are not accurate or representative. Accurate and educational online prevention materials should be created to decrease the occurrence of TCG.

Vaccine-critical videos on YouTube and their impact on medical students' attitudes about seasonal influenza immunization: a pre and post study.

2012-05-28

YouTube is a video-sharing platform that is increasingly utilized to share and disseminate health-related information about immunization. Using a pre-post survey methodology, we compared the impact of two of the most popular YouTube videos discussing seasonal influenza vaccine, both vaccine-critical, on the attitudes towards immunizing of first year medical students attending a Canadian medical school. Forty-one medical students were randomized to view either a scientifically styled, seemingly "evidence-based", vaccine-critical video or a video using anecdotal stories of harms and highly sensationalized imagery. In the pre-intervention survey, medical students frequently used YouTube for all-purposes, while 42% used YouTube for health-related purposes and 12% used YouTube to search for health information. While medical students were generally supportive of immunizing, there was suboptimal uptake of annual influenza vaccine reported, and a subset of our study population expressed vaccine-critical attitudes and behaviors with respect to seasonal influenza. Overall there was no significant difference in pre to post attitudes towards influenza immunization nor were there any differences when comparing the two different vaccine-critical videos. The results of our study are reassuring in that they suggest that medical students are relatively resistant to the predominately inaccurate, vaccine-critical messaging on YouTube, even when the message is framed as scientific reasoning. Further empirical work is required to test the popular notion that information disseminated through social media platforms influences health-related attitudes and behaviors. However, our study suggests that there is an opportunity for public health to leverage YouTube to communicate accurate and credible information regarding influenza to medical students and others.

To study postings of partial asphyxiation by adolescents on YouTube and to increase awareness of this dangerous activity as well as the value of YouTube as a research tool. Videos were searched on YouTube using many terms for recreational partial asphyxiation. Data were gathered on the participants and on the occurrence of hypoxic seizure. Sixty-five videos of the asphyxiation game were identified. Most (90%) participants were male. A variety of techniques were used. Hypoxic seizures were witnessed in 55% of videos, but occurred in 88% of videos that employed the "sleeper hold" technique. The videos were collectively viewed 173550 times on YouTube. YouTube has enabled millions of young people to watch videos of the "choking game" and other dangerous activities. Seeing videos may normalize the behavior among adolescents. Increased awareness of this activity may prevent some youths from participating and potentially harming themselves or others.

YouTube as an online video-sharing service in the context of Web 2.0 goes beyond the bounds of pure fun, for which the platform was primarily established. Nowadays, commonly to other social media, it serves also educational, informational and last but not least, marketing purposes. The importance of video sharing is supported by several predictions about video reaching over 90% of global internet traffic by 2020. Using qualitative content analysis over selected YouTube videos, paper examines the current situation of the platform's marketing potential usage by medical informatics organizations, researches and other healthcare professionals. Results of the analysis demonstrate several ways in which YouTube is already used to inform, educate or promote above-mentioned medical institutions. However, their engagement in self-promo or spreading awareness of their research projects via YouTube is considered to be low.

The objective of this paper was to examine the educational potential and effectiveness of a 3 min video clip of a simulation of schizophrenia published online at YouTube. Researchers examined the 267 public comments published on the video-sharing website YouTube over 8 years by viewers of a schizophrenia simulation video titled "virtual hallucinations" made in the Second Life game platform. Comments were independently categorized into six groupings, then cooperatively finalized, and qualitatively analyzed. The six categories of style of comments were "Emotional" (n = 76), "Identification" (n = 62), "Educational Interest" (n = 45), "Mocking/Displeased" (n = 36), "Game Interest" (n = 32), and "Other" (n = 25). Without any advertising or marketing by the creators, over 194,400 views of the video were recorded in 8 years, an average of about 1500 views per month. The use of YouTube with its viral marketing potential has created a vastly amplified reach for this educational offering that would otherwise have been impossible. Qualitative analysis of publically posted comments in response to the video, which were generally positive, has led to a greater understanding of public reactions to such educational offerings. YouTube videos are already a rich source of data for psychiatric researchers, and psychiatric educators should consider posting high quality video clips on publically available social media platforms such as YouTube in order to reduce public stigma about psychiatric disorders and patients.

The use of online social networks in medical education can remodel and enhance anatomy teaching and learning; one such network is the video-sharing site YouTube. Limited research in the literature exists on the use of YouTube as a platform for anatomy education. The aim of this study is to assess student's perceptions and patterns of usage of this resource, as well as the effectiveness of YouTube videos within a problem-based learning (PBL) curriculum. The study was conducted on 91 second-year medical students for whom video links were suggested throughout the academic year. In addition, the Human Anatomy Education (HAE) Channel was launched on YouTube to support classroom teaching with videos that emphasized applied aspects of anatomy. The results demonstrated that 98% of the students used YouTube as an online information resource, albeit in different frequencies. Out of the 86% who have been to the HAE Channel, 92% agreed/strongly agreed that the channel helped them learn anatomy. The study also reports the popularity of and awareness about using YouTube as a social network as well as in learning. Based on these findings, YouTube can be considered as an effective tool to enhance anatomy instruction if the videos are scrutinized, diversified, and aimed toward course objectives. Faculty of average computer literacy should be enabled to produce videos on their own YouTube channels to support independent learning and integration in a PBL curriculum. The methods described for capturing and editing the videos can be used as a prototype. Copyright © 2012 American Association of Anatomists.

In Italy, the phenomenon of vaccine hesitancy has increased with time and represents a complex problem that requires a continuous monitoring. Misinformation on media and social media seems to be one of the determinants of the vaccine hesitancy since, for instance, 42.8 percent of Italian citizens used the internet to obtain vaccine information in 2016. This article reports a quantitative analysis of 560 YouTube videos related to the link between vaccines and autism or other serious side effects on children. The analysis revealed that most of the videos were negative in tone and that the annual number of uploaded videos has increased during the considered period, that goes from 27 December 2007 to 31 July 2017, with a peak of 224 videos in the first seven months of 2017. These findings suggest that the public institutions should be more engaged in establishing a web presence in order to provide reliable information, answers, stories, and videos so to respond to questions of the public about vaccination. These actions could be useful to allow citizens to make informed decisions about vaccines so to comply with vaccination regulations.

Web 2.0 sites such as YouTube have become a useful resource for knowledge and are used by medical students as a learning resource. This study aimed at assessing videos covering the nervous system examination on YouTube. A research of YouTube was conducted from 2 November to 2 December 2011 using the following key words "nervous system examination", "nervous system clinical examination", "cranial nerves examination", "CNS examination", "examination of cerebellum", "balance and coordination examination". Only relevant videos in the English language were identified and related URL recorded. For each video, the following information was collected: title, author/s, duration, number of viewers, number of posted comments, and total number of days on YouTube. Using criteria comprising content, technical authority and pedagogy parameters, videos were rated independently by three assessors and grouped into educationally useful and non-educationally useful. A total of 2240 videos were screened; 129 were found to have relevant information to nervous system examination. Analysis revealed that 61 (47%) of the videos provided useful information on the nervous system examination. These videos scored (mean ± SD, 14.9 ± 0.2) and mainly covered examination of the whole nervous system (8 videos, 13%), cranial nerves (42 videos, 69%), upper limbs (6 videos, 10%), lower limbs (3 videos, 5%), balance and co-ordination (2 videos, 3%). The other 68 (53%) videos were not useful educationally; scoring (mean ± SD, 11.1 ± 3.0). The total viewers of all videos was 2,189,434.

2013-01-01

An increasing amount of health education resources for patients and professionals are distributed via social media channels. For example, thousands of health education videos are disseminated via YouTube. Often, tags are assigned by the disseminator. However, the lack of use of standardized terminologies in those tags and the presence of misleading videos make it particularly hard to retrieve relevant videos. i) Identify the use of standardized medical thesauri (SNOMED CT) in YouTube Health videos tags from preselected YouTube Channels and demonstrate an information technology (IT) architecture for treating the tags of these health (video) resources. ii) Investigate the relative percentage of the tags used that relate to SNOMED CT terms. As such resources may play a key role in educating professionals and patients, the use of standardized vocabularies may facilitate the sharing of such resources. iii) Demonstrate how such resources may be properly exploited within the new generation of semantically enriched content or learning management systems that allow for knowledge expansion through the use of linked medical data and numerous literature resources also described through the same vocabularies. We implemented a video portal integrating videos from 500 US Hospital channels. The portal integrated 4,307 YouTube videos regarding surgery as described by 64,367 tags. BioPortal REST services were used within our portal to match SNOMED CT terms with YouTube tags by both exact match and non-exact match. The whole architecture was complemented with a mechanism to enrich the retrieved video resources with other educational material residing in other repositories by following contemporary semantic web advances, in the form of Linked Open Data (LOD) principles. The average percentage of YouTube tags that were expressed using SNOMED CT terms was about 22.5%, while one third of YouTube tags per video contained a SNOMED CT term in a loose search; this analogy became one tenth in

Can "YouTube" help students in learning surface anatomy?

2012-07-01

In a problem-based learning curriculum, most medical students research the Internet for information for their "learning issues." Internet sites such as "YouTube" have become a useful resource for information. This study aimed at assessing YouTube videos covering surface anatomy. A search of YouTube was conducted from November 8 to 30, 2010 using research terms "surface anatomy," "anatomy body painting," "living anatomy," "bone landmarks," and "dermatomes" for surface anatomy-related videos. Only relevant video clips in the English language were identified and related URL recorded. For each videotape the following information were collected: title, authors, duration, number of viewers, posted comments, and total number of days on YouTube. The data were statistically analyzed and videos were grouped into educationally useful and non-useful videos on the basis of major and minor criteria covering technical, content, authority, and pedagogy parameters. A total of 235 YouTube videos were screened and 57 were found to have relevant information to surface anatomy. Analysis revealed that 15 (27%) of the videos provided useful information on surface anatomy. These videos scored (mean ± SD, 14.0 ± 0.7) and mainly covered surface anatomy of the shoulder, knee, muscles of the back, leg, and ankle, carotid artery, dermatomes, and anatomical positions. The other 42 (73%) videos were not useful educationally, scoring (mean ± SD, 7.4 ± 1.8). The total viewers of all videos were 1,058,634. Useful videos were viewed by 497,925 (47% of total viewers). The total viewership per day was 750 for useful videos and 652 for non-useful videos. No video clips covering surface anatomy of the head and neck, blood vessels and nerves of upper and lower limbs, chest and abdominal organs/structures were found. Currently, YouTube is an inadequate source of information for learning surface anatomy. More work is needed from medical schools and educators to add useful videos on YouTube

There is little research that characterises knee pain related information disseminated via social media. However, variances in the content and quality of such sources could compromise optimal patient care. This study explored the nature of the comments on YouTube videos related to non-specific knee pain, to determine their helpfulness to the users. A systematic search identified 900 videos related to knee pain on the YouTube database. A total of 3537 comments from 58 videos were included in the study. A categorisation scheme was developed and 1000 randomly selected comments were analysed according to this scheme. The most common category was the users providing personal information or describing a personal situation (19%), followed by appreciation or acknowledgement of others' inputs (17%) and asking questions (15%). Of the questions, 33% were related to seeking help in relation to a specific situation. Over 10% of the comments contained negativity or disagreement; while 4.4% of comments reported they intended to pursue an action, based on the information presented in the video and/or from user comments. It was observed that individuals commenting on YouTube videos on knee pain were most often soliciting advice and information specific to their condition. The analysis of comments from the most commented videos using a keyword-based search approach suggests that the YouTube videos can be used for disseminating general advice on knee pain.

YouTube may be viewed as a great 'time waster' but a significant amount of educative material can be found if the user is carefully selective. Interestingly, the growth of educational video on YouTube is closely associated to video viewership which increased from 22% to 38% between 2007 and 2009. This paper describes the findings of a study undertaken to assess the quality of clinical skills videos available on the video sharing site YouTube. This study evaluated 100 YouTube sites, approximately 1500 min or 25 h worth of content across 10 common clinical skill related topics. In consultation with novice practitioners, nurses in the first year of their university diploma programme, we identified ten common clinical skills that typically students would explore in more detail or would wish to revisit outside of the formal teaching environment. For each of these topics, we viewed each of the first 10 videos on the YouTube website. The videos were evaluated using a modification of the criteria outlined in Evaluation of Video Media Guideline. The topic with the biggest number of both postings and views was cardiopulmonary resuscitation and more specialist, nursing or health related topics such as managing a syringe driver or undertaking a pain assessment had less video content and lower numbers of viewers. Only one video out of the 100 analysed could be categorised as 'good' and that was the one in the Cannulation section. 60% of the CPR and venepuncture content was categorised as 'satisfactory'. There is a clear need for the quality of YouTube videos to be subjected to a rigorous evaluation. Lecturers should be more proactive in recommending suitable YouTube material as supplementary learning materials after appropriately checking for quality. Copyright © 2013 Elsevier Ltd.

STEREOVIDEO channel (https://www.youtube.com/user/geostereovideo) is a YouTube channel of short educational videos (<5 min) focused on learning the handling of the stereographic projection technique applied to Structural Geology (also to Engineering Geology). This type of videos aims to reinforce the traditional classroom lessons with the use of communication technologies resources. Such a reinforcing facilitates the possibility to deepen more on conceptual aspects once the students dominate the representation tool helping them to develop their own critical thinking skills. After three years of being launched on-line (on 2014), we analyze the broadcast and acceptance of the channel by the academic community. For this purpose we have taken into account two different sources: (1) the analytics tool from YouTube (subscriptions, views, countries, comments from the users, type of device for viewing), and (2) our own survey among users (students and teachers) to get their opinion about the videos. By January, 2017 (date of sending of this abstract), the channel has a total of 650 subscriptions, with more than 85,000 views all around the world, mainly in Spanish speaking countries (as the videos are in Spanish). The main devices for viewing the videos are PCs, but is noteworthy the use of smart phones and tablets. The video users, both students and teachers, value this type of content positively.

YouTube is a highly utilized Web site that contains a large amount of medical educational material. Although some studies have assessed the education material contained on the Web site, little analysis of cardiology content has been made. This study aimed to assess the quality of videos relating to heart sounds and murmurs contained on YouTube. We hypothesized that the quality of video files purporting to provide education on heart auscultation would be highly variable. Videos were searched for using the terms "heart sounds," "heart murmur," and "heart auscultation." A built-in educational filter was employed, and manual rejection of non-English language and nonrelated videos was undertaken. Remaining videos were analyzed for content, and suitable videos were scored using a purpose-built tool. YouTube search located 3350 videos in total, and of these, 22 were considered suitable for scoring. The average score was 4.07 out of 7 (standard deviation, 1.35). Six videos scored 5.5 or greater and 5 videos scoring 2.5 or less. There was no correlation between video score and YouTube indices of preference (hits, likes, dislikes, or search page). The quality of videos found in this study was highly variable. YouTube indications of preference were of no value in determining the value of video content. Therefore, teaching institutions or professional societies should endeavor to identify and highlight good online teaching resources. YouTube contains many videos relating to cardiac auscultation, but very few are valuable education resources. © 2012 Wiley Periodicals, Inc.

INTRODUCTION Videos promoting electronic cigarettes (e-cigarettes) can be easily accessed on YouTube. Marketing claims present in YouTube videos may help shape the public’s opinion of e-cigarettes. Thus, it is important to understand the most frequent marketing claims and video sources. METHODS The objectives of this study were to 1) identify marketing claims in YouTube videos that are commonly made on e-cigarette retail websites and 2) compare the frequency of marketing claims in user-generated and professional YouTube videos. Through content analysis, this study evaluated six marketing claims and descriptive information about YouTube videos (n = 50) related to “electronic cigarettes” and “vape”. RESULTS Overall, the most frequent marketing claim promoted e-cigarette use as better than traditional tobacco use (52%). Approximately 65% of videos appeared to be user-generated and 35% were professionally-produced. Compared to user-generated videos, significantly more professional videos made claims that e-cigarettes are cleaner (p < 0.001) and cheaper (p = 0.04) than traditional cigarettes. Additionally, more professional videos had claims promoting e-cigarettes as better than traditional cigarettes because of their convenience—the user can smoke anywhere (p < 0.0001) and the products do not produce secondhand smoke (p < 0.001). The most frequent claim in user-generated videos was related to recreation (53%). CONCLUSIONS Videos on YouTube promote e-cigarettes as safer than other tobacco products. Videos appearing to be user-generated contained different marketing claims compared to professional videos. Further research is necessary to assess how the perceived source of the video impacts the ways these marketing claims shape public perception and influence use. PMID:28725876

Infertility patients frequently use the internet to find fertility-related information and support from people in similar circumstances. YouTube is increasingly used as a source of health-related information and may influence health decision making. There have been no studies examining the content of infertility-related videos on YouTube. The purpose of this study was to (1) describe the content of highly viewed videos on YouTube related to infertility and (2) identify video characteristics that relate to viewer preference. Using the search term "infertility," the 80 top-viewed YouTube videos and their viewing statistics (eg, views, likes, and comments) were collected. Videos that were non-English, unrelated to infertility, or had age restrictions were excluded. Content analysis was used to examine videos, employing a coding rubric that measured the presence or absence of video codes related to purpose, tone, and demographic and fertility characteristics (eg, sex, parity, stage of fertility treatment). A total of 59 videos, with a median of 156,103 views, met the inclusion criteria and were categorized into 35 personal videos (35/59, 59%) and 24 informational-educational videos (24/59, 41%). Personal videos did not differ significantly from informational-educational videos on number of views, dislikes, subscriptions driven, or shares. However, personal videos had significantly more likes (P<.001) and comments (P<.001) than informational-educational videos. The purposes of the videos were treatment outcomes (33/59, 56%), sharing information (30/59, 51%), emotional aspects of infertility (20/59, 34%), and advice to others (6/59, 10%). The tones of the videos were positive (26/59, 44%), neutral (25/59, 42%), and mixed (8/59, 14%); there were no videos with negative tone. No videos contained only male posters. Videos with a positive tone did not differ from neutral videos in number of views, dislikes, subscriptions driven, or shares; however, positive videos had

The objective of this study was to systematically assess the informational value, intention, source, and bias of videos related to dentistry available on the video-sharing Internet platform YouTube. YouTube (www.youtube.com) was searched for videos related to dentistry, using the system-generated sorts "by relevance" and "most viewed" and two categories (All and Education). Each of the first thirty results was rated by two assessors filling out a questionnaire for each (total: 120). The data were subjected to statistical analysis using Cohen's kappa, Pearson's correlation coefficient tau, Mann-Whitney U-tests, and a nonparametric three-way ANOVA, including an analysis of the interaction between the sorting and category effect, with an α-level of 5 percent. The scan produced 279,000 results in the category All and 5,050 in the category Education. The analysis revealed a wide variety of information about dentistry available on YouTube. The purpose of these videos includes entertainment, advertising, and education. The videos classified under Education have a higher degree of usefulness and informational value for laypersons, dental students, and dental professionals than those found in a broader search category. YouTube and similar social media websites offer new educational possibilities that are currently both underdeveloped and underestimated in terms of their potential value. Dentists and dental educators should also recognize the importance of these websites in shaping public opinion about their profession.

Exposure to lead is detrimental to children's development. YouTube is a form of social media through which people may learn about lead poisoning. The aim of this cross-sectional study was to analyze the variation in lead poisoning-related YouTube contents between different video sources. The 100 most viewed lead poisoning-related videos were manually coded, among which, 50 were consumer-generated, 19 were created by health care professionals, and 31 were news. The 100 videos had a total of more than 8.9 million views, with news videos accounting for 63% of those views. The odds of mentioning what lead poisoning is, how to remove lead, and specifically mentioning the danger in ages 1-5 because of rapid growth among videos created by health care professionals were 7.28 times (Odds ratio, OR = 7.28, 95% CI, 2.09, 25.37, p = 0.002); 6.83 times (OR = 6.83, 95% CI, 2.05, 22.75, p = 0.002) and 9.14 times (OR = 9.14, CI, 2.05, 40.70, p = 0.004) that of consumer-generated videos, respectively. In this study, professional videos had more accurate information regarding lead but their videos were less likely to be viewed compared to consumer-generated videos and news videos. If professional videos about lead poisoning can attract more viewers, more people would be better informed and could possibly influence policy agendas, thereby helping communities being affected by lead exposure.

Background: Use of multivitamin/multimineral (MVM) and other dietary supplements is common among American adults. The purpose of this study was to describe the source and content of the most widely viewed YouTube videos associated with MVM supplements. Methods: Videos were filtered by number of views and the source of the video upload was recorded. A comparison of video characteristics and differences in video content was conducted. Results: Cumulatively, the videos in this sample were viewed 25 573 055 times. The majority of videos found in this sample were uploaded by a nutrition, wellness, or fitness channels. Most videos mentioned benefits (80.4%, 95% CI: 72.5%, 88.3%) and advocated for use of the supplement (72.2%, 95% CI: 63.3%, 81.1%). Over 84% (84.5%, 95% CI: 77.3, 91.7%) of the videos did not mention risks associated with taking a particular vitamin or supplement. Conclusion: The findings of this study indicate that MVMs are often promoted and encouraged, yet risks associated with MVMs were infrequently mentioned. Health professionals should be aware of the extent to which MVM related content appears on social media and, more importantly, be attuned to the content, which can be misleading, or missing information regarding risks and/or evidence of possible benefits.

YouTube is a video-sharing website that is increasingly used to share and disseminate health-related information, particularly among younger people. There are reports that social media sites, such as YouTube, are being used to communicate an anti-psychiatry message but this has never been confirmed in any published analysis of YouTube clip content. This descriptive study revealed that the representation of 'psychiatry' during summer 2012 was predominantly negative. A subsequent smaller re-analysis suggests that the negative portrayal of 'psychiatry' on YouTube is a stable phenomenon. The significance of this and how it could be addressed are discussed.

Video2vec Embeddings Recognize Events When Examples Are Scarce.

PubMed

Habibian, Amirhossein; Mensink, Thomas; Snoek, Cees G M

2017-10-01

This paper aims for event recognition when video examples are scarce or even completely absent. The key in such a challenging setting is a semantic video representation. Rather than building the representation from individual attribute detectors and their annotations, we propose to learn the entire representation from freely available web videos and their descriptions using an embedding between video features and term vectors. In our proposed embedding, which we call Video2vec, the correlations between the words are utilized to learn a more effective representation by optimizing a joint objective balancing descriptiveness and predictability. We show how learning the Video2vec embedding using a multimodal predictability loss, including appearance, motion and audio features, results in a better predictable representation. We also propose an event specific variant of Video2vec to learn a more accurate representation for the words, which are indicative of the event, by introducing a term sensitive descriptiveness loss. Our experiments on three challenging collections of web videos from the NIST TRECVID Multimedia Event Detection and Columbia Consumer Videos datasets demonstrate: i) the advantages of Video2vec over representations using attributes or alternative embeddings, ii) the benefit of fusing video modalities by an embedding over common strategies, iii) the complementarity of term sensitive descriptiveness and multimodal predictability for event recognition. By its ability to improve predictability of present day audio-visual video features, while at the same time maximizing their semantic descriptiveness, Video2vec leads to state-of-the-art accuracy for both few- and zero-example recognition of events in video.

Cervical cancer is the third most common cancer worldwide. Accurate information about cervical cancer to general public can lower the burden of the disease including its mortality. We aimed to look at the quality of information available in YouTube for cervical cancer. We searched YouTube (http://www.youtube.com) for videos using the keyword Cervical cancer on November 12, 2015. Videos were then analyzed for their source and content of information. We studied 172 videos using the keyword Cervical cancer on November 12, 2015. We found that there were videos describing the personal stories, risk factors, and the importance of screening. However, videos discussing all the aspects of cancers were lacking. Likewise, videos from the reputed organization were also lacking. Although there were numerous videos available in cervical cancer, videos from reputed organizations including Center for Disease Control and Prevention, American Cancer Society, and World Health Organization were lacking. We strongly believe that quality videos from such organizations via YouTube can help lower the burden of disease.

Recent publications on YouTube have advocated its potential for patient education. However, a reliable description of what could be considered quality information for patient education on YouTube is missing. To identify topics associated with the concept of quality information for patient education on YouTube in the scientific literature. A literature review was performed in MEDLINE, ISI Web of Knowledge, Scopus, and PsychINFO. Abstract selection was first conducted by two independent reviewers; discrepancies were discussed in a second abstract review with two additional independent reviewers. Full text of selected papers were analyzed looking for concepts, definitions, and topics used by its authors that focused on the quality of information on YouTube for patient education. In total, 456 abstracts were extracted and 13 papers meeting eligibility criteria were analyzed. Concepts identified related to quality of information for patient education are categorized as expert-driven, popularity-driven, or heuristic-driven measures. These include (in descending order): (1) quality of content in 10/13 (77%), (2) view count in 9/13 (69%), (3) health professional opinion in 8/13 (62%), (4) adequate length or duration in 6/13 (46%), (5) public ratings in 5/13 (39%), (6) adequate title, tags, and description in 5/13 (39%), (7) good description or a comprehensive narrative in 4/13 (31%), (8) evidence-based practices included in video in 4/13 (31%), (9) suitability as a teaching tool in 4/13 (31%), (10) technical quality in 4/13 (31%), (11) credentials provided in video in 4/13 (31%), (12) enough amount of content to identify its objective in 3/13 (23%), and (13) viewership share in 2/13 (15%). Our review confirms that the current topics linked to quality of information for patient education on YouTube are unclear and not standardized.

Wavelet-based audio embedding and audio/video compression

NASA Astrophysics Data System (ADS)

Mendenhall, Michael J.; Claypoole, Roger L., Jr.

2001-12-01

Watermarking, traditionally used for copyright protection, is used in a new and exciting way. An efficient wavelet-based watermarking technique embeds audio information into a video signal. Several effective compression techniques are applied to compress the resulting audio/video signal in an embedded fashion. This wavelet-based compression algorithm incorporates bit-plane coding, index coding, and Huffman coding. To demonstrate the potential of this audio embedding and audio/video compression algorithm, we embed an audio signal into a video signal and then compress. Results show that overall compression rates of 15:1 can be achieved. The video signal is reconstructed with a median PSNR of nearly 33 dB. Finally, the audio signal is extracted from the compressed audio/video signal without error.

Can YouTube enhance student nurse learning?

PubMed

Clifton, Andrew; Mann, Claire

2011-05-01

The delivery of nurse education has changed radically in the past two decades. Increasingly, nurse educators are using new technology in the classroom to enhance their teaching and learning. One recent technological development to emerge is the user-generated content website YouTube. Originally YouTube was used as a repository for sharing home-made videos, more recently online content is being generated by political parties, businesses and educationalists. We recently delivered a module to undergraduate student nurses in which the teaching and learning were highly populated with YouTube resources. We found that the use of YouTube videos increased student engagement, critical awareness and facilitated deep learning. Furthermore, these videos could be accessed at any time of the day and from a place to suit the student. We acknowledge that there are some constraints to using YouTube for teaching and learning particularly around the issue of unregulated content which is often misleading, inaccurate or biased. However, we strongly urge nurse educators to consider using YouTube for teaching and learning, in and outside the classroom, to a generation of students who are native of a rapidly changing digital world.

YouTube is an important resource for patients. No study has evaluated the information on peripheral neuropathy disseminated by YouTube videos. In this study, our aim was to perform a systematic review of information on YouTube regarding peripheral neuropathy. The Web site (www.youtube.com) was searched between September 19 and 21, 2014, for the terms "neuropathy," "peripheral neuropathy," "diabetic neuropathy," "neuropathy causes," and "neuropathy treatment." Two hundred videos met the inclusion criteria. Healthcare professionals accounted for almost half of the treatment videos (41 of 92; 44.6%), and most came from chiropractors (18 of 41; 43.9%). Alternative medicine was cited most frequently among the treatment discussions (54 of 145, 37.2%), followed by devices (38 of 145, 26.2%), and pharmacological treatments (23 of 145, 15.9%). Approximately half of the treatment options discussed in the videos were not evidence-based. Caution should be exercised when YouTube videos are used as a patient resource. © 2015 Wiley Periodicals, Inc.

Background Dabbing involves heating marijuana extracts to a high temperature and inhaling the vapor. Little is known about this new method of using marijuana. YouTube, the most popular platform for sharing online videos, may be a go-to resource for individuals interested in learning about dabbing. Our objective was to explore the content of dabbing-related videos on YouTube. Methods We searched for dabbing related videos on YouTube using the search terms “dabbing” and “dabs” on January 22, 2015. For each term, videos were sorted by relevance and view count. A sample of 116 dabbing videos were viewed and coded for content. Results The 116 videos (published by 75 unique channels) had a total of 9,545,482 views. Most (76%) of the channels had a specific focus on marijuana and 23% were located in California. 89% of the videos showed at least one person dabbing, and 61% of these showed someone dabbing repeatedly. Most dabbers were male (67%) and many appeared to be >25 years old (42%). Approximately 34% of the videos contained a product review, 28% provided instructions on dabbing or other educational information, and 21% contained at least a brief cautionary message. Over half (54%) of the videos referenced medical marijuana, and only 20% of the videos had an age restriction. Conclusions Dabbing-related videos are easily found and can be readily viewed on YouTube. As marijuana use becomes more accepted by the general population, the popularity of dabbing-related videos could increase, potentially normalizing this potent form of marijuana use. PMID:26347408

We currently live in a world filled with videos. There are videos on YouTube, feature movies and even videos recorded with our own cameras and smartphones. These videos present an excellent opportunity to not only explore physical concepts, but also inspire others to investigate physics ideas. With video analysis, we can explore the fantasy world in science-fiction films. We can also look at online videos to determine if they are genuine or fake. Video analysis can be used in the introductory physics lab and it can even be used to explore the make-believe physics embedded in video games. This book covers the basic ideas behind video analysis along with the fundamental physics principles used in video analysis. The book also includes several examples of the unique situations in which video analysis can be used.

To date, this column has presented videos to show in class, Don Mathieson from Tulsa Community College suggested that YouTube could be used in another fashion. In Don's experience, his students are not always prepared for the mathematic rigor of his course. Even at the high school level, math can be a barrier for physics students. Walid Shihabi, a colleague of Don's, decided to compile a list of YouTube videos that his students could watch to relearn basic mathematics. I thought this sounded like a fantastic idea and a great service to the students. Walid graciously agreed to share his list and I have reproduced a large portion of it below.

This study examined the prevalence, accessibility, and characteristics of eroticized smoking portrayal, also referred to as smoking fetish, on YouTube. The analysis of 200 smoking fetish videos revealed that the smoking fetish videos are prevalent and accessible to adolescents on the website. They featured explicit smoking behavior by sexy, young, and healthy females, with the content corresponding to PG-13 and R movie ratings. We discuss a potential impact of the prosmoking image on youth according to social cognitive theory, and implications for tobacco control.

YouTube has become a useful resource for knowledge and is widely used by medical students as an e-learning source. The purpose of this study was to assess the videos relating electrocardiogram (ECG) on YouTube. YouTube was searched on May 28, 2013 for the search terms "AF ecg" for atrial fibrillation, "AVNRT" for atrioventricular nodal reentrant tachycardia, "AVRT" for atrioventricular reentrant tachycardia, "AV block or heart block" for atrioventricular block, "LBBB, RBBB" for bundle branch block, "left anterior fascicular block or left posterior fascicular block" for fascicular blocks, "VT ecg" for ventricular tachycardia, "long QT" and "Brugada ecg". Non-English language, unrelated and non-educational videos were excluded. Remaining videos were assessed for usefulness, source and characteristics. Usefulness was assessed with using a checklist developed by the authors. One hundred nineteen videos were included in the analysis. Sources of the videos were as follows: individuals n=70, 58.8%, universities/hospitals n=10, 8.4% and medical organizations n=3, 2.5%, health ads n=10 8.4%, health websites n=26, 21.8%. Fifty-six (47.1%) videos were classified as very useful and 16 (13.4%) videos were misleading. 90% of the videos uploaded by universities/hospitals were grouped as very useful videos, the same ratio was 45% for the individual uploads. There were statistically significant differences in ECG diagnosis among the groups (for very useful, useful and misleading, p<0.001, 0.02 and 0.008, respectively). The ratio of the misleading information in ventricular tachycardia videos was found to be 42.9%. YouTube has a substantial amount of videos on ECG with a wide diversity from useful to misleading content. The lack of quality content relating to ECG on YouTube necessitates that videos should be selected with utmost care. © 2013 Elsevier Inc. All rights reserved.

We sought to determine public perception surrounding Tourette syndrome through viewers' responses to videos on YouTube. The top 20 videos on YouTube for search terms Tourette's, Tourette's syndrome, Tourette syndrome and tics were selected. The portrayal of Tourette syndrome was assessed as positive, negative, or neutral. Top 10 comments for each video were graded as "sympathetic," "neutral," or "derogatory." A total of 14 970 hits were obtained and 41 videos were retained, with an average of 590 113 views (1369 to 13 747 069) and 1761 comments (0 to 35 241). Twenty-two percent of videos retained portrayed Tourette syndrome negatively, 20% were neutral and 59% positive. Negative portrayals were significantly associated with more views (Spearman correlation rho = -.46, P =.003) and comments (Spearman correlation rho = -.47, P = .002). Although excellent examples of Tourette syndrome are available on YouTube, the popularity of negative portrayals may reinforce existing stigma in society.

Enhancing student interactions with the instructor and content using pen-based technology, YouTube videos, and virtual conferencing.

This report describes the incorporation of digital learning elements in organic chemistry and biochemistry courses. The first example is the use of pen-based technology and a large-format PowerPoint slide to construct a map that integrates various metabolic pathways and control points. Students can use this map to visualize the integrated nature of metabolism and how various hormones impact metabolic regulation. The second example is the embedding of health-related YouTube videos directly into PowerPoint presentations. These videos become a part of the course notes and can be viewed within PowerPoint as long as students are online. The third example is the use of a webcam to show physical models during online sessions using web-conferencing software. Various molecular conformations can be shown through the webcam, and snapshots of important conformations can be incorporated into the notes for further discussion and annotation. Each of the digital learning elements discussed in this report is an attempt to use technology to improve the quality of educational resources available outside of the classroom to foster student engagement with ideas and concepts.

Background Direct ophthalmoscopy is well-suited for video-based instruction, particularly if the videos enable the student to see what the examiner sees when performing direct ophthalmoscopy. We evaluated the pedagogical effectiveness of instructional YouTube videos on direct ophthalmoscopy by evaluating their content and approach to visualization. Methods In order to synthesize main themes and points for direct ophthalmoscopy, we formed a broad panel consisting of a medical student, junior and senior physicians, and took into consideration book chapters targeting medical students and physicians in general. We then systematically searched YouTube. Two authors reviewed eligible videos to assess eligibility and extract data on video statistics, content, and approach to visualization. Correlations between video statistics and contents were investigated using two-tailed Spearman’s correlation. Results We screened 7,640 videos, of which 27 were found eligible for this study. Overall, a median of 12 out of 18 points (interquartile range: 8–14 key points) were covered; no videos covered all of the 18 points assessed. We found the most difficulties in the approach to visualization of how to approach the patient and how to examine the fundus. Time spent on fundus examination correlated with the number of views per week (Spearman’s ρ=0.53; P=0.029). Conclusion Videos may help overcome the pedagogical issues in teaching direct ophthalmoscopy; however, the few available videos on YouTube fail to address this particular issue adequately. There is a need for high-quality videos that include relevant points, provide realistic visualization of the examiner’s view, and give particular emphasis on fundus examination. PMID:27574393

YouTube and ‘psychiatry’

YouTube is a video-sharing website that is increasingly used to share and disseminate health-related information, particularly among younger people. There are reports that social media sites, such as YouTube, are being used to communicate an anti-psychiatry message but this has never been confirmed in any published analysis of YouTube clip content. This descriptive study revealed that the representation of ‘psychiatry’ during summer 2012 was predominantly negative. A subsequent smaller re-analysis suggests that the negative portrayal of ‘psychiatry’ on YouTube is a stable phenomenon. The significance of this and how it could be addressed are discussed.

Infant vaccinations are necessary for public health, but are painful, causing distress to the infant and caregivers. Breastfeeding and sucrose effectively reduce infants' pain during vaccinations, and these strategies are recommended in health care provider (HCP)-targeted education and vaccination pain guidelines. However studies show these strategies are infrequently used. YouTube is a popular medium to publicly share and watch videos, and many consumer posted YouTube videos show distressed infants being vaccinated with no pain treatment. The aims of this study were to evaluate the reach and impact of a consumer-targeted YouTube video demonstrating use of effective pain reduction strategies during infant vaccinations. A brief consumer-targeted video showing two infants being vaccinated was posted onto YouTube on October 2013. One infant was breastfed and another infant received sucrose by mouth before and during the injection. A link to a viewer survey was visible on a banner near the end of the video. An intensive strategically planned knowledge dissemination strategy using the media, social media and messages to professional organizations took place to promote the video. Data analysis of the viewer survey, YouTube analytics of the reach of the video in terms of number of views, country of viewers, and comments relating to the video took place 12 months after the video was posted. Twelve months after posting, the video had 65,478views, 68 comments, 245 likes, 17 dislikes, and 90 shares. Average duration of viewer time was 65% of the video. The viewer survey was completed by 156 (0.24%) viewers; 90 (58%) answered as HCPs and 66 (42%) as parents. Survey results showed that the video was persuasive; intent to use or support breastfeeding or sucrose was high in both parents and HCPs after viewing the video. Comments posted were often emotional in nature, and were related to anti-vaccination (n = 26, 38%); effectiveness or positive personal experiences (n = 21, 32

Lewis, Stephen P; Heath, Nancy L; St Denis, Jill M; Noble, Rick

2011-03-01

Nonsuicidal self-injury, the deliberate destruction of one's body tissue (eg, self-cutting, burning) without suicidal intent, has consistent rates ranging from 14% to 24% among youth and young adults. With more youth using video-sharing Web sites (eg, YouTube), this study examined the accessibility and scope of nonsuicidal self-injury videos online. Using YouTube's search engine (and the following key words: "self-injury" and "self-harm"), the 50 most viewed character (ie, with a live individual) and noncharacter videos (100 total) were selected and examined across key quantitative and qualitative variables. The top 100 videos analyzed were viewed over 2 million times, and most (80%) were accessible to a general audience. Viewers rated the videos positively (M = 4.61; SD: 0.61 out of 5.0) and selected videos as a favorite over 12 000 times. The videos' tones were largely factual or educational (53%) or melancholic (51%). Explicit imagery of self-injury was common. Specifically, 90% of noncharacter videos had nonsuicidal self-injury photographs, whereas 28% of character videos had in-action nonsuicidal self-injury. For both, cutting was the most common method. Many videos (58%) do not warn about this content. The nature of nonsuicidal self-injury videos on YouTube may foster normalization of nonsuicidal self-injury and may reinforce the behavior through regular viewing of nonsuicidal self-injury-themed videos. Graphic videos showing nonsuicidal self-injury are frequently accessed and received positively by viewers. These videos largely provide nonsuicidal self-injury information and/or express a hopeless or melancholic message. Professionals working with youth and young adults who enact nonsuicidal self-injury need to be aware of the scope and nature of nonsuicidal self-injury on YouTube.

To analyze seizure-like motor phenomena immediately occurring after concussion (concussive convulsions). Twenty-five videos of concussive convulsions were obtained from YouTube as a result of numerous sports-related search terms. The videos were analyzed by four independent observers, documenting observations of the casualty, the head injury, motor symptoms of the concussive convulsions, the postictal period, and the outcome. Immediate responses included the fencing response, bear hug position, and bilateral leg extension. Fencing response was the most common. The side of the hit (p = 0.039) and the head turning (p = 0.0002) was ipsilateral to the extended arm. There was a tendency that if the blow had only a vertical component, the bear hug position appeared more frequently (p = 0.12). The motor symptom that appeared with latency of 6 ± 3 s was clonus, sometimes superimposed with tonic motor phenomena. Clonus was focal, focally evolving bilateral or bilateral, with a duration of 27 ± 19 s (5-72 s). Where lateralization of clonus could be determined, the side of clonus and the side of hit were contralateral (p = 0.039). Concussive convulsions consist of two phases. The short-latency first phase encompasses motor phenomena resembling neonatal reflexes and may be of brainstem origin. The long-latency second phase consists of clonus. We hypothesize that the motor symptoms of the long-latency phase are attributed to cortical structures; however, they are probably not epileptic in origin but rather a result of a transient cortical neuronal disturbance induced by mechanical forces.

2016-12-01

To assess the content and completeness of Youtube ™ as an information source for patients undergoing root canal treatment procedures. YouTube ™ (https://www.youtube.com/) was searched for information using three relevant treatment search terms ('endodontics', 'root canal' and 'root canal treatment'). After exclusions (language, no audio, >15 min, duplicates), 20 videos per search term were selected. General video assessment included duration, ownership, views, age, likes/dislikes, target audience and video/audio quality, whilst content was analysed under six categories ('aetiology', 'anatomy', 'symptoms', 'procedure', 'postoperative course' and 'prognosis'). Content was scored for completeness level and statistically analysed using anova and post hoc Tukey's test (P < 0.05). To obtain 60 acceptable videos, 124 were assessed. Depending on the search term employed, the video content and ownership differed markedly. There was wide variation in both the number of video views and 'likes/dislikes'. The average video age was 788 days. In total, 46% of videos were 'posted' by a dentist/specialist source; however, this was search term specific rising to 70% of uploads for the search 'endodontic', whilst laypersons contributed 18% of uploads for the search 'root canal treatment'. Every video lacked content in the designated six categories, although 'procedure' details were covered more frequently and in better detail than other categories. Videos posted by dental professional (P = 0.046) and commercial sources (P = 0.009) were significantly more complete than videos posted by laypeople. YouTube ™ videos for endodontic search terms varied significantly by source and content and were generally incomplete. The danger of patient reliance on YouTube ™ is highlighted, as is the need for endodontic professionals to play an active role in directing patients towards alternative high-quality information sources. © 2015 International Endodontic Journal.

2010-04-01

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has received literally thousands of video-posts of people using salvia. The objective of this study was to assess the effects of salvia use through systematic observations of YouTube videos. A sample of salvia videos was obtained using the search term "salvia." The videos were further screened and only videos that captured the entire drug "trip" without video edits were included in the analyses described here (n=34). Three trained research assistants independently watched the videos and rated their observations on 42 effects in 30-s intervals. Onset of symptoms was quick (often less than 30s) and tended to dissipate within 8min. Further, there was a relationship between salvia dose and effect duration. Since salvia's effects on humans are largely undocumented, this study provides the look at users in a non-laboratory environment (e.g. self-taped videos) exhibiting impairments and behaviors consistent with this powerful hallucinogen. Also, this study demonstrates the feasibility and shortcomings of using YouTube videos to assess emerging drugs and drug effects. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

This study examines the content of and audience response to organ donation videos on YouTube, a Web 2.0 platform, with framing theory. Positive frames were identified in both video content and audience comments. Analysis revealed a reciprocity relationship between media frames and audience frames. Videos covered content categories such as kidney, liver, organ donation registration process, and youth. Videos were favorably rated. No significant differences were found between videos produced by organizations and individuals in the United States and those produced in other countries. The findings provide insight into how new communication technologies are shaping health communication in ways that differ from traditional media. The implications of Web 2.0, characterized by user-generated content and interactivity, for health communication and health campaign practice are discussed.

Blunts are partially or fully hollowed-out cigars or cigarillos that are filled with marijuana. Despite the high prevalence of blunt use, very few studies assess this specific method of cannabis administration. YouTube, a popular video-sharing website, has the potential to provide insights into blunt use. The purpose of this study was to examine the content of YouTube videos that discuss blunts. A sample of 41 videos was coded for content. The 41 videos had a total of 27,579,636 views. Most of the individuals in the videos were male (85%) and many appeared to be White (80%) and under the age of 25 (46%). Only 34% of the videos had an age restriction. The majority of messages in the videos promoted blunt use (93%) and showed at least one person rolling (76%) and/or smoking (66%) a blunt. The videos mainly consisted of introductions to blunt use (76%) and tips and personal experiences with blunt use (73%). YouTube videos on blunt use are readily available and primarily promote the use of blunts. Future research should continue to monitor YouTube content and develop videos on social media platforms that inform consumers of the health effects associated with blunt use.

Cranwell, Jo; Britton, John; Bains, Manpreet

2017-02-01

The purpose of the present study is to describe the portrayal of alcohol content in popular YouTube music videos. We used inductive thematic analysis to explore the lyrics and visual imagery in 49 UK Top 40 songs and music videos previously found to contain alcohol content and watched by many British adolescents aged between 11 and 18 years and to examine if branded content contravened alcohol industry advertising codes of practice. The analysis generated three themes. First, alcohol content was associated with sexualised imagery or lyrics and the objectification of women. Second, alcohol was associated with image, lifestyle and sociability. Finally, some videos showed alcohol overtly encouraging excessive drinking and drunkenness, including those containing branding, with no negative consequences to the drinker. Our results suggest that YouTube music videos promote positive associations with alcohol use. Further, several alcohol companies adopt marketing strategies in the video medium that are entirely inconsistent with their own or others agreed advertising codes of practice. We conclude that, as a harm reduction measure, policies should change to prevent adolescent exposure to the positive promotion of alcohol and alcohol branding in music videos.

Nowadays, YouTube is the 3rd most visited website in the world. It was created for users to search, watch and share video. Statistics show that YouTube run in more than 88 countries and support 76 different languages which covered almost 95% of Internet population globally. Therefore, a usability study is for specific type of users such as based on gender, range of age and country is considered a must for this kind of top website. In this study, we focus on YouTube website usability for Malaysian teenagers that are currently schooling in boarding school with limited access of Internet. It was done in a controlled lab environment with proper devices and software as MacBook, LCD Monitor, and WhatPulse heat map tracker. The evaluation was made based on usability metrics: ease of use, usefulness and satisfaction of users with combination of recording videos, mouse and keyboard heat map and questionnaires. Findings show that most of the respondents just use YouTube for video watching only while ignoring other features in the same time. There are difficulties in using it at the first moment but could catch up in short time. It shows how usable YouTube website especially in the learnability and memorability aspects.

Counteracting the Influence of Peer Smoking on YouTube.

2017-04-01

YouTube, a popular online site for user-generated content, is emerging as a powerful source of peer modeling of smoking. Previous research suggests that in counteracting such influence, health messages may inadvertently increase the perceived prevalence of drug use (a descriptive norm) without reducing its acceptability (injunctive norm). This research tested the ability of health messages to reduce the social acceptability of peer smoking on YouTube despite enhancing its perceived prevalence. In an online experiment with 999 adolescents, participants were randomly assigned to view one of two videos: (a) a mosaic displaying a variety of YouTube videos of adolescents smoking followed by a message about the mortality risk to those smokers, or (b) a control video on a health topic unrelated to smoking. Although exposure to the adolescent YouTube smokers increased perceived prevalence among some participants, it simultaneously increased beliefs about smoking's adverse health outcomes and negative attitudes toward smoking, effects that were associated with reductions in injunctive norms of social acceptability. Interventions that communicate the severity and scope of health risks associated with smoking may undercut the descriptive normative effects of peer modeling of smoking on social media sites such as YouTube.

Visual content highlighting via automatic extraction of embedded captions on MPEG compressed video

NASA Astrophysics Data System (ADS)

Yeo, Boon-Lock; Liu, Bede

1996-03-01

Embedded captions in TV programs such as news broadcasts, documentaries and coverage of sports events provide important information on the underlying events. In digital video libraries, such captions represent a highly condensed form of key information on the contents of the video. In this paper we propose a scheme to automatically detect the presence of captions embedded in video frames. The proposed method operates on reduced image sequences which are efficiently reconstructed from compressed MPEG video and thus does not require full frame decompression. The detection, extraction and analysis of embedded captions help to capture the highlights of visual contents in video documents for better organization of video, to present succinctly the important messages embedded in the images, and to facilitate browsing, searching and retrieval of relevant clips.

We conducted a 4-month investigation to determine HCP satisfaction with a nephrology-specific YouTube channel. The Nephrology On-Demand YouTube channel was analyzed from January 1 through April 30, 2011. Sixty-minute nephrology lectures at East Carolina University were compressed into 10-minute videos and uploaded to the channel. HCPs were asked to answer a 5-point Likert questionnaire regarding the accuracy, currency, objectivity and usefulness of the digital format of the teaching videos. Means, standard deviations and 2-sided chi-square testing were performed to analyze responses. Over 80% of HCPs considered the YouTube channel to be accurate, current and objective. A similar percentage considered the digital format useful despite the compression of videos and lack of audio. The nephrology-specific YouTube channel has the potential to educate HCPs of various training backgrounds. Additional studies are required to determine if such specialty-specific channels can improve knowledge acquisition and retention.

YouTube as a source of information for obstructive sleep apnea.

PubMed

Singh, Sameer K; Liu, Stanley; Capasso, Robson; Kern, Robert C; Gouveia, Christopher J

Assess the quality of information on obstructive sleep apnea (OSA) presented on YouTube for patients. "Obstructive sleep apnea" was entered into the YouTube search. Two independent reviewers categorized and analyzed videos utilizing a customized scoring-system along with search position, likes, and views. Forty-eight videos were analyzed. Most were educational (52.1%). Educational and news videos had significantly higher scores, but had no significant differences in search position, likes/day, or views/day. Most videos mentioned positive airway pressure (65%), and nearly half (44%) mentioned mandibular devices in the management of OSA. Few videos discussed surgery (13%) or otolaryngology (15%). YouTube is a promising source of information for OSA patients. Educational and news videos are of highest quality. General quality measures like search position, views, and likes are not correlated with formally scored value. Sleep surgery and otolaryngologists are minimally mentioned, representing an opportunity for improvement. Copyright © 2018 Elsevier Inc. All rights reserved.

The current West Africa epidemic of Ebola virus disease (EVD), which began from Guinea in December 2013, has been the longest and deadliest Ebola outbreak to date. With the propagation of the internet, public health officials must now compete with other official and unofficial sources of information to get their message out. This study aimed at critically appraising videos available on one popular internet video site (YouTube) as a source of information for Ebola virus disease (EVD). Videos were searched in YouTube (http://www.youtube.com) using the keyword "Ebola outbreak" from inception to November 1, 2014 with the default "relevance" filter. Only videos in English language under 10 min duration within first 10 pages of search were included. Duplicates were removed and the rest were classified as useful or misleading by two independent reviewers. Video sources were categorized by source. Inter-observer agreement was evaluated with kappa coefficient. Continuous and categorical variables were analyzed using the Student t-test and Chi-squared test, respectively. One hundred and eighteen out of 198 videos were evaluated. Thirty-one (26.27%) videos were classified as misleading and 87 (73.73%) videos were classified as useful. The kappa coefficient of agreement regarding the usefulness of the videos was 0.68 (P < 0.001). Independent users were more likely to post misleading videos (93.55% vs 29.89%, OR = 34.02, 95% CI = 7.55-153.12, P < 0.001) whereas news agencies were most likely to post useful videos (65.52% vs 3.23%, OR = 57.00, 95% CI = 7.40-438.74, P < 0.001). This study demonstrates that majority of the internet videos about Ebola on YouTube were characterized as useful. Although YouTube seems to generally be a useful source of information on the current outbreak, increased efforts to disseminate scientifically correct information is desired to prevent unnecessary panic among the among the general population.

In this digital era, there is a growing tendency to use the popular Internet site YouTube as a new electronic-learning (e-learning) means for continuing medical education. Heart transplantation (HTx) remains the most viable option for patients with end-stage heart failure or severe coronary artery disease. There are plenty of freely accessible YouTube videos providing medical information about HTx. The aim of the present study is to determine the effectiveness of YouTube as an e-learning source on HTx. In order to carry out this study, YouTube was searched for videos uploaded containing surgical-related information using the four keywords: (1) "heart transplantation", (2) "cardiac transplantation", (3) "heart transplantation operation", and (4) "cardiac transplantation operation". Only videos in English (with comments or subtitles in English language) were included. Two experienced cardiac surgeons watched each video (N=1800) and classified them as useful, misleading, or recipients videos based on the HTx-relevant information. The kappa statistic was used to measure interobserver variability. Data was analyzed according to six types of YouTube characteristics including "total viewership", "duration", "source", "days since upload", "scores" given by the viewers, and specialized information contents of the videos. A total of 342/1800 (19.00%) videos had relevant information about HTx. Of these 342 videos, 215 (62.8%) videos had useful information about specialized knowledge, 7/342 (2.0%) were found to be misleading, and 120/342 (35.1%) only concerned recipients' individual issues. Useful videos had 56.09% of total viewership share (2,175,845/3,878,890), whereas misleading had 35.47% (1,375,673/3,878,890). Independent user channel videos accounted for a smaller proportion (19% in total numbers) but might have a wider impact on Web viewers, with the highest mean views/day (mean 39, SD 107) among four kinds of channels to distribute HTx-related information.

2017-01-01

YouTube, a popular online site for user-generated content, is emerging as a powerful source of peer modeling of smoking. Previous research suggests that in counteracting such influence, health messages may inadvertently increase the perceived prevalence of drug use (a descriptive norm) without reducing its acceptability (injunctive norm). This research tested the ability of health messages to reduce the social acceptability of peer smoking on YouTube despite enhancing its perceived prevalence. In an online experiment with 999 adolescents, participants were randomly assigned to view one of two videos: (a) a mosaic displaying a variety of YouTube videos of adolescents smoking followed by a message about the mortality risk to those smokers, or (b) a control video on a health topic unrelated to smoking. Although exposure to the adolescent YouTube smokers increased perceived prevalence among some participants, it simultaneously increased beliefs about smoking’s adverse health outcomes and negative attitudes toward smoking, effects that were associated with reductions in injunctive norms of social acceptability. Interventions that communicate the severity and scope of health risks associated with smoking may undercut the descriptive normative effects of peer modeling of smoking on social media sites such as YouTube.

This study investigated videos about Attention Deficit Hyperactivity Disorder (ADHD) on YouTube in terms of issues, sources, and episodic-thematic aspects. A total of 685 videos uploaded onto YouTube between 2006 and 2014 were content analyzed. Results demonstrated that the top three key issues about ADHD were symptom, child, and treatment. Doctor, patient, and supporter were the three most interviewed sources. Videos from the public sector including the government, company representative, and public organizations were relatively rare compared to other sources suggesting the potential for a greater role for the government and public sector contributions to YouTube to provide credible information relevant to public awareness, campaigns, and policy announcements. Meanwhile, many personal videos in the episodic frame advocated social solutions. This result implies that YouTube videos about health information from the private sectors have the potential to affect change at the social level.

Viewer discretion advised: is YouTube a friend or foe in surgical education?

In the current era, trainees frequently use unvetted online resources for their own education, including viewing surgical videos on YouTube. While operative videos are an important resource in surgical education, YouTube content is not selected or organized by quality but instead is ranked by popularity and other factors. This creates a potential for videos that feature poor technique or critical safety violations to become the most viewed for a given procedure. A YouTube search for "Laparoscopic cholecystectomy" was performed. Search results were screened to exclude animations and lectures; the top ten operative videos were evaluated. Three reviewers independently analyzed each of the 10 videos. Technical skill was rated using the GOALS score. Establishment of a critical view of safety (CVS) was scored according to CVS "doublet view" score, where a score of ≥5 points (out of 6) is considered satisfactory. Videos were also screened for safety concerns not listed by the previous tools. Median competence score was 8 (±1.76) and difficulty was 2 (±1.8). GOALS score median was 18 (±3.4). Only one video achieved adequate critical view of safety; median CVS score was 2 (range 0-6). Five videos were noted to have other potentially dangerous safety violations, including placing hot ultrasonic shears on the duodenum, non-clipping of the cystic artery, blind dissection in the hepatocystic triangle, and damage to the liver capsule. Top ranked laparoscopic cholecystectomy videos on YouTube show suboptimal technique with half of videos demonstrating concerning maneuvers and only one in ten having an adequate critical view of safety. While observing operative videos can be an important learning tool, surgical educators should be aware of the low quality of popular videos on YouTube. Dissemination of high-quality content on video sharing platforms should be a priority for surgical societies.

This article reviews the peer-reviewed literature addressing the healthcare information available on YouTube. Inclusion and exclusion criteria were determined, and the online databases PubMed and Web of Knowledge were searched using the search phrases: (1) YouTube* AND Health* and (2) YouTube* AND Healthcare*. In all, 18 articles were reviewed, with the results suggesting that (1) YouTube is increasingly being used as a platform for disseminating health information; (2) content and frame analysis were the primary techniques employed by researchers to analyze the characteristics of this information; (3) YouTube contains misleading information, primarily anecdotal, that contradicts the reference standards and the probability of a lay user finding such content is relatively high; (4) the retrieval of relevant videos is dependent on the search term used; and (5) videos from government organizations and professional associations contained trustworthy and high-quality information. YouTube is used as a medium for promoting unscientific therapies and drugs that are yet to be approved by the appropriate agencies and has the potential to change the beliefs of patients concerning controversial topics such as vaccinations. This review recognizes the need to design interventions to enable consumers to critically assimilate the information posted on YouTube with more authoritative information sources to make effective healthcare decisions. © The Author(s) 2014.

The recent Ebola virus disease (EVD) outbreak in 2014-2015 has been the largest and longest lasting to date. Media coverage about the outbreak has been extensive, but there are large gaps in our understanding of the ways in which widely accessed social media sites are used during times of public health crisis. The purpose of this study was to analyze widely viewed videos about EVD on the YouTube video-sharing site. We coded the source, content, and characteristics of the 100 most widely viewed videos about EVD on YouTube. The videos included in the sample were viewed more than 73 million times. The death toll in West Africa was mentioned in nearly one-third of the videos. Over one-third of the videos mentioned how EVD was generally transmitted. There was little mention of treatment and no mention of the need for US funding of disaster preparedness; coordination between local, state, and federal governments; or beds ready for containment. No significant differences in the number of views were identified between video sources with the exception of a significantly higher number of views for "consumer videos" compared with "commercial television videos." With 1 billion unique users a month, YouTube has potential for both enhancing education and spreading misinformation.

E-cigarettes are widely promoted on the Internet, but little is known about what kinds of information about them are available online. This study examines message, source, and health information characteristics of e-cigarette videos on the popular online video-sharing platform YouTube. A content analysis of 365 e-cigarette videos indicates that 85% of the videos were sponsored by marketers. These videos highlight e-cigarettes' economic and social benefits, featuring a low level of fear appeal and negative message valence and a high level of marketing information about e-cigarette products. They also convey certain health claims that have been proscribed by the U.S. Food and Drug Administration, the prevalence of which warrants ongoing monitoring and regulatory guidelines for online e-cigarette marketing.

The global prevalence of sedentary lifestyles is of grave concern for public health around the world. Moreover, the health risk of sedentary behaviors is of growing interest for researchers, clinicians, and the general public as evidence demonstrates that prolonged amounts of sedentary time increases risk for lifestyle-related diseases. There is a growing trend in the literature that reports how social media can facilitate knowledge sharing and collaboration. Social sites like YouTube facilitate the sharing of media content between users. The purpose of this project was to identify sedentary behavior content on YouTube and describe features of this content that may impact the effectiveness of YouTube for knowledge translation. YouTube was searched on a single day by 3 independent reviewers for evidence-based sedentary behavior content. Subjective data (eg, video purpose, source, and activity type portrayed) and objective data (eg, number of views, comments, shares, and length of the video) were collected from video. In total, 106 videos met inclusion criteria. Videos were uploaded from 13 countries around the globe (ie, Australia, Barbados, Belgium, Canada, Colombia, Kenya, New Zealand, Russia, South Africa, Spain, Ukraine, United Kingdom, United States). The median video length was 3:00 minutes: interquartile range (IQR) 1:44-5:40. On average, videos had been on YouTube for 15.0 months (IQR 6.0-27.5) and had been viewed 239.0 times (IQR 44.5-917.5). Videos had remarkably low numbers of shares (median 0) and comments (median 1). Only 37.7% (40/106) of videos portrayed content on sedentary behaviors, while the remaining 66 videos portrayed physical activity or a mix of behaviors. Academic/health organizations (39.6%, 42/106) and individuals (38.7%, 41/106) were the most prevalent source of videos, and most videos (67.0%, 71/106) aimed to educate viewers about the topic.

Background YouTube, the online video creation and sharing site, supports both video content viewing and content creation activities. For a minority of people, the time spent engaging with YouTube can be excessive and potentially problematic. Method This study analyzed the relationship between content viewing, content creation, and YouTube addiction in a survey of 410 Indian-student YouTube users. It also examined the influence of content, social, technology, and process gratifications on user inclination toward YouTube content viewing and content creation. Results The results demonstrated that content creation in YouTube had a closer relationship with YouTube addiction than content viewing. Furthermore, social gratification was found to have a significant influence on both types of YouTube activities, whereas technology gratification did not significantly influence them. Among all perceived gratifications, content gratification had the highest relationship coefficient value with YouTube content creation inclination. The model fit and variance extracted by the endogenous constructs were good, which further validated the results of the analysis. Conclusion The study facilitates new ways to explore user gratification in using YouTube and how the channel responds to it.

Scant literature exists about the quality of urogynecological content on social media. Our objective was to measure the accuracy and comprehensiveness of YouTube videos related to mid-urethral sling (MUS) procedures. YouTube was searched using the terms "mid-urethral sling," "vaginal tape," "TVT," "TOT," "TVT surgery," and "TOT surgery." Duplicates and videos with less than 1,000 views were excluded. We developed a standardized questionnaire for this project, assessing each video's target audience, main purpose, relevance, informed consent elements, surgical steps, and bias. The primary outcome was the presence of all elements of informed consent. Inter-rater reliability (IRR) was calculated using the Fleiss' kappa statistic. Descriptive statistics were also obtained. Five reviewers each rated 56 videos. Mean IRR was moderate (Fleiss' kappa 0.58 ± 0.24). Video content was classified as physician educational material (67.9 %), patient information (16.1 %), advertisement (10.7 %), lawsuit recruitment (1.8 %), and unclear (3.6 %). MUS was the primary topic for 82.1 % of the videos. The remainder discussed other types of anti-incontinence procedures or prolapse surgery. None of the videos mentioned all four elements of informed consent. Of 32 videos demonstrating surgical technique, none showed the complete list of pre-determined surgical steps. The mean number of listed steps was 7.6/16. Only four videos mentioned at least one post-operative patient instruction. A marketing element was shown in 26.8 % of videos. Patient information about MUS on YouTube is lacking and often biased. Physicians and students viewing YouTube videos for educational purposes should be cognizant of the variability in the surgical steps demonstrated.

The aim of this study was to evaluate the reliability, content, and quality of videos for patients available on YouTube for learning how to self-administer subcutaneous anti-tumour necrosis factor (TNF) injections. We searched for the terms Humira injection, Enbrel injection, Simponi injection, and Cimzia injection. Videos were categorised as useful information, misleading information, useful patient opinion, and misleading patient opinion by two physicians. Videos were rated for quality on a 5-point global quality scale (GQS; 1 = poor quality, 5 = excellent quality) and reliability and content using the 5-point DISCERN scale (higher scores represent greater reliability and more comprehensive videos). Of the 142 English videos, 24 (16.9%) videos were classified as useful information, 6 (4.2%) as misleading information, 47 (33.1%) as useful patient opinion, and 65 (45.8%) as misleading patient opinion. Useful videos were the most comprehensive and had the highest reliability and quality scores. The useful information and useful patient opinion videos had the highest numbers of views per day (median 8.32, IQR: 3.40-14.28 and 5.46, IQR: 3.06-14.44), as compared with 2.32, IQR: 1.63-6.26 for misleading information videos and 2.15, IQR: 1.17-7.43 for misleading patient opinion videos (p = 0.001). Almost all (91.5%) misleading videos were uploaded by individual users. There are a substantial number of English-language YouTube videos, with high quality, and rich content and reliability that can be sources of information on proper technique of anti-TNF self-injections. Physicians should direct patients to the reliable resources of information and educate them in online resource assessment, thereby improving treatment outcomes.

To conduct analyses to determine the extent to which YouTube videos posted specific to smoking cessation were actually about quitting smoking and if so, whether or not they portrayed evidence-based practices (EBPs). In August 2008, researchers identified YouTube videos by search strategies, 'relevance' and 'view count' using the following three search terms: 'stop smoking', 'quit smoking' and 'smoking cessation (n=296 for full sample and n=191 for unique videos). Overall, almost 60% of videos contained a message about quitting smoking. Differences were found across search terms for videos about quitting smoking, with 'stop smoking' yielding the highest percentage (80.8%) of videos about quitting smoking. Almost half of the videos (48.9%) contained EBPs for cessation strategies; however, a significant portion contained either non--EBPs (28.4%) or both EBPs and non-EBPs (22.7%). The number of views per an individual video across the six categories ranged from a low of 8 in the 'relevance' strategy and 'smoking cessation' search term to a high of 1,247,540 in the 'view count' strategy and 'stop smoking' search term. Of the top three most viewed videos by strategy and search term, 66.7% included a specific mention of quitting smoking and, of these, the majority included EBPs. Results highlight the need to develop and upload videos containing EBPs both to increase the overall proportion of EBP videos in all categories, particularly in 'quit smoking' and 'stop smoking.' Research is needed to study whether YouTube videos influence knowledge, attitudes and behaviours regarding quitting smoking.

To investigate the quality of YouTube videos on gallstone disease and to assess viewer response according to quality. A YouTube search was performed on September 18, 2013, using the keywords ''gallbladder disease'', ''gallstone disease'', and ''gallstone treatment''. Three researchers assessed the source, length, number of views, number of likes, and days since upload. The upload source was categorised as physician or hospital (PH), medical website or TV channel, commercial website (CW), or civilian. A usefulness score was devised to assess video quality and to categorise the videos into ''very useful'', ''useful'', ''slightly useful'', or ''not useful''. Videos with misleading content were categorised as ''misleading''. One hundred and thirty-one videos were analysed. Seventy-four videos (56.5%) were misleading, 36 (27.5%) were slightly useful, 15 (11.5%) were useful, three (2.3%) were very useful, and three (2.3%) were not useful. The number of mean likes (1.3 ± 1.5 vs 17.2 ± 38.0, P = 0.007) and number of views (756.3 ± 701.0 vs 8910.7 ± 17094.7, P = 0.001) were both significantly lower in the very useful group compared with the misleading group. All three very useful videos were PH videos. Among the 74 misleading videos, 64 (86.5%) were uploaded by a CW. There was no correlation between usefulness and the number of views, the number of likes, or the length. The "gallstone flush" was the method advocated most frequently by misleading videos (25.7%). More than half of the YouTube videos on gallstone disease are misleading. Credible videos uploaded by medical professionals and filtering by the staff of YouTube appear to be necessary.

Informational value and bias of videos related to orthodontics screened on a video-sharing Web site.

2011-05-01

To assess the informational value, intention, source, and bias of videos related to orthodontics screened by the video-sharing Internet platform YouTube. YouTube (www.youtube.com) was scanned in July 2010 for orthodontics-related videos using an adequately defined search term. Each of the first 30 search results of the scan was categorized with the system-generated sorts "by relevance" and "most viewed" (total: 60). These were rated independently by three assessors, who completed a questionnaire for each video. The data were analyzed statistically using Friedman's test for dependent samples, Kendall's tau, and Fleiss's kappa. The YouTube scan produced 5140 results. There was a wide variety of information about orthodontics available on YouTube, and the highest proportion of videos was found to originate from orthodontic patients. These videos were also the most viewed ones. The informational content of most of the videos was generally judged to be low, with a rather poor to inadequate representation of the orthodontic profession, although a moderately pro-orthodontics stance prevailed. It was noticeable that the majority of contributions of orthodontists to YouTube constituted advertising. This tendency was not viewed positively by the majority of YouTube users, as was evident in the divergence in the proportions when sorting by "relevance" and "most viewed." In the light of the very large number of people using the Internet as their primary source of information, orthodontists should recognize the importance of YouTube and similar social media Web sites in the opinion-forming process, especially in the case of adolescents.

This study was conducted to assess the quantity, quality, and reach of e-cigarette health effects YouTube videos, and to quantify the description of positive and negative e-cigarette health effects and promotional content in each video. Searches for videos were conducted in 2015 using the YouTube search engine, and the top 20 search results by relevance and view count were identified. Videos were classified by educational/medical news, advertising/marketing, and personal/testimonial categories. A coding sheet was used to assess the presence or absence of negative and positive health effects, and promotional content. Of the 320 videos retrieved, only 55 unique videos were included. The majority of videos (46.9%) were educational/medical/news, 29.7% were personal/testimonial, and 23.4% were advertising/marketing. The three most common negative health effects included discussing nicotine, e-cigarettes not being FDA regulated, and known and unknown health consequences related to e-cigarette use. The top positive health effects discussed were how e-cigarettes can help individuals quit smoking, e-cigarettes are healthier than smoking, and e-cigarettes have no smoke or secondhand smoke exposure. It is critical to monitor YouTube health effects content and develop appropriate messages to inform consumers about the risks associated with use while mitigating misleading information presented.

ePatients on YouTube: Analysis of Four Experiences From the Patients' Perspective

PubMed Central

Gómez-Zúñiga, Beni; Pousada, Modesta; Hernández-Encuentra, Eulàlia; Armayones, Manuel

2012-01-01

Background Many patients share their personal experiences and opinions using online video platforms. These videos are watched by millions of health consumers and health care professionals. Although it has become a popular phenomenon, little is known about patients who share videos online and why they do so. Objective We aimed to explore the motivations and challenges faced by patients who share videos about their health and experiences on YouTube. As part of a conference discussion, we asked several patients actively engaged on YouTube to make a video explaining their motivations. This paper discusses these videos. Methods In this qualitative study, we performed an analysis of the videos created by 4 patients about their self-reported motivations and challenges they face as YouTube users. First, two judges compared the transcriptions and decided the exact wording when confusing content was found. Second, two judges categorized the content of the videos to identify the major themes. Results Four main categories emerged: (1) the origin or cause for making the first video, (2) the objectives that they achieve by continuing to make videos, (3) the perception of community, and (4) the negative consequences of the experience. Conclusions The main reason for making videos was to bridge the gap between traditional health information about their diseases and everyday life. The first consequence of sharing their life on YouTube was a loss of privacy. However, they also experienced the positive effects of expressing their feelings, being part of a large community of peers, and helping others to deal with a chronic condition. PMID:25075229

"I'll be your cigarette--light me up and get on with it": examining smoking imagery on YouTube.

PubMed

Forsyth, Susan R; Malone, Ruth E

2010-08-01

Smoking imagery on the online video sharing site YouTube is prolific and easily accessed. However, no studies have examined how this content changes across time. We studied the primary message and genre of YouTube videos about smoking across two time periods. In May and July 2009, we used "cigarettes" and "smoking cigarettes" to retrieve the top 20 videos on YouTube by relevance and view count. Eliminating duplicates, 124 videos were coded for time period, overall message, genre, and brand mentions. Data were analyzed using descriptive statistics. Videos portraying smoking positively far outnumbered smoking-negative videos in both samples, increasing as a percentage of total views across the time period. Fifty-eight percent of videos in the second sample were new. Among smoking-positive videos, music and magic tricks were most numerous, increasing from 66% to nearly 80% in July, with music accounting for most of the increase. Marlboro was the most frequently mentioned brand. Videos portraying smoking positively predominate on YouTube, and this pattern persists across time. Tobacco control advocates could use YouTube more effectively to counterbalance prosmoking messages.

2018-01-01

YouTube's online archive of video testimonials related to health information are more commonly viewed than those developed by clinicians and professional groups, suggesting the importance of the patient experience to viewers. We specifically sought to examine the accuracy of information on, and projected acceptability of, the intrauterine device (IUD) from these YouTube testimonials. We searched YouTube for videos about individual uploaders' IUD experiences, using the search terms 'intrauterine device', 'IUD', 'Mirena' and 'Paragard'. Given interest in user testimonials, we excluded professional and instructional videos belonging to commercial or non-profit entities. Two reviewers independently analysed the videos using a structured guide, with attention to inaccurate information. Of 86 identified videos, four videos featured clinicians and were excluded; 62 met inclusion criteria. Interrater agreement on IUD portrayal was good (K=0.73). Young (mean age 25, range 19-38, years), white (75%), nulliparous (61%) women primarily uploaded content. Most described placement of the LNG-IUS (65%), were posted within 1 month of insertion (45%), and mentioned side effects (66%) - bleeding, pain, and partner sensation of the strings. About one-third of videos contained inaccurate information (34%) and were thought to project an overall negative experience (30%). Videos portraying IUDs negatively were associated with inaccurate information and/or mention of side effects. While one-third of IUD user testimonials on YouTube contained inaccurate information, the majority of IUD experiences were perceived by our study viewers to be positive. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Lee, Jun Suh; Seo, Ho Seok

2015-01-01

Purpose The purpose of this study was to analyze the educational quality of laparoscopic cholecystectomy (LC) videos accessible on YouTube, one of the most important sources of internet-based medical information. Methods The keyword 'laparoscopic cholecystectomy' was used to search on YouTube and the first 100 videos were analyzed. Among them, 27 videos were excluded and 73 videos were included in the study. An arbitrary score system for video quality, devised from existing LC guidelines, were used to evaluate the quality of the videos. Video demographics were analyzed by the quality and source of the video. Correlation analysis was performed. Results When analyzed by video quality, 11 (15.1%) were evaluated as 'good', 40 (54.8%) were 'moderate', and 22 (30.1%) were 'poor', and there were no differences in length, views per day, or number of likes, dislikes, and comments. When analyzed by source, 27 (37.0%) were uploaded by primary centers, 20 (27.4%) by secondary centers, 15 (20.5%) by tertiary centers, 5 (6.8%) by academic institutions, and 6 (8.2%) by commercial institutions. The mean score of the tertiary center group (6.0 ± 2.0) was significantly higher than the secondary center group (3.9 ± 1.4, P = 0.001). The video score had no correlation with views per day or number of likes. Conclusion Many LC videos are accessible on YouTube with varying quality. Videos uploaded by tertiary centers showed the highest educational value. This discrepancy in video quality was not recognized by viewers. More videos with higher quality need to be uploaded, and an active filtering process is necessary. PMID:26236699

Wen, Nainan; Chia, Stella C; Hao, Xiaoming

2015-01-01

This study examines portrayals of cosmetic surgery on YouTube, where we found a substantial number of cosmetic surgery videos. Most of the videos came from cosmetic surgeons who appeared to be aggressively using social media in their practices. Except for videos that explained cosmetic surgery procedures, most videos in our sample emphasized the benefits of cosmetic surgery, and only a small number of the videos addressed the involved risks. We also found that tactics of persuasive communication-namely, related to message source and message sensation value (MSV)-have been used in Web-based social media to attract viewers' attention and interests. Expert sources were used predominantly, although typical-consumer sources tended to generate greater viewer interest in cosmetic surgery than other types of message sources. High MSV, moreover, was found to increase a video's popularity.

Asthma affects >300 million people globally, including 25 million in the United States. Patients with asthma frequently use the Internet as a source of information. YouTube is one of the three most popular Web sites. To determine the educational quality of YouTube videos for asthma. We performed a YouTube search by using the keyword "asthma." The 200 most frequently viewed relevant videos were included in the study. Asthma videos were analyzed for characteristics, source, and content. Source was further classified as asthma health care provider, other health care provider, patient, pharmaceutical company, and professional society and/or media. A scoring system was created to evaluate quality (-10 to 30 points). Negative points were assigned for misleading information. Two hundred videos were analyzed, with a median of 18,073.5 views, 31.5 likes, and 2 dislikes, which spanned a median of 172 seconds. More video presenters were male (60.5%). The most common type of video source was other health care providers (34.5%). The most common video content was alternative treatments (38.0%), including live-fish ingestion; reflexology; acupressure and/or acupuncture; Ayurveda; yoga; raw food, vegan, gluten-free diets; marijuana; Buteyko breathing; and salt therapy. Scores for videos supplied by asthma health care providers were statistically significantly different from other sources (p < 0.001) and had the highest average score (9.91). YouTube videos of asthma were frequently viewed but were a poor source of accurate health care information. Videos by asthma health care providers were rated highest in quality. The allergy/immunology community has a clear opportunity to enhance the value of educational material on YouTube.

Raikos, Athanasios; Waidyasekara, Pasan

2014-01-01

Nowadays more and more modern medical degree programs focus on self-directed and problem-based learning. That requires students to search for high quality and easy to retrieve online resources. YouTube is an emerging platform for learning human anatomy due to easy access and being a free service. The purpose of this study is to make a quantitative and qualitative analysis of the available human heart anatomy videos on YouTube. Using the search engine of the platform we searched for relevant videos using various keywords. Videos with irrelevant content, animal tissue, non-English language, no sound, duplicates, and physiology focused were excluded from further elaboration. The initial search retrieved 55,525 videos, whereas only 294 qualified for further analysis. A unique scoring system was used to assess the anatomical quality and details, general quality, and the general data for each video. Our results indicate that the human heart anatomy videos available on YouTube conveyed our anatomical criteria poorly, whereas the general quality scoring found borderline. Students should be selective when looking up on public video databases as it can prove challenging, time consuming, and the anatomical information may be misleading due to absence of content review. Anatomists and institutions are encouraged to prepare and endorse good quality material and make them available online for the students. The scoring rubric used in the study comprises a valuable tool to faculty members for quality evaluation of heart anatomy videos available on social media platforms.

YouTube as a source of information on rhinosinusitis: the good, the bad and the ugly.

PubMed

Biggs, T C; Bird, J H; Harries, P G; Salib, R J

2013-08-01

YouTube is an internet-based repository of user-generated content. This study aimed to determine whether YouTube represented a valid and reliable patient information resource for the lay person on the topic of rhinosinusitis. The study included the first 100 YouTube videos found using the search term 'sinusitis'. Videos were graded on their ability to inform the lay person on the subject of rhinosinusitis. Forty-five per cent of the videos were deemed to provide some useful information. Fifty-five per cent of the videos contained little or no useful facts, 27 per cent of which contained potentially misleading or even dangerous information. Videos uploaded by medical professionals or those from health information websites contained more useful information than those uploaded by independent users. YouTube appears to be an unreliable resource for accurate and up to date medical information relating to rhinosinusitis. However, it may provide some useful information if mechanisms existed to direct lay people to verifiable and credible sources.

Cranwell, Jo; Opazo-Breton, Magdalena; Britton, John

2016-05-01

We estimate exposure of British adults and adolescents to tobacco and alcohol content from a sample of popular YouTube music videos. British viewing figures were generated from 2 representative online national surveys of adult and adolescent viewing of the 32 most popular videos containing content. 2068 adolescents aged 11-18 years (1010 boys, 1058 girls), and 2232 adults aged 19+years (1052 male, 1180 female) completed the surveys. We used the number of 10 s intervals in the 32 most popular videos containing content to estimate the number of impressions. We extrapolated gross and per capita impressions for the British population from census data and estimated numbers of adults and adolescents who had ever watched the sampled videos. From video release to the point of survey, the videos delivered an estimated 1006 million gross impressions of alcohol (95% CI 748 to 1264 million), and 203 million of tobacco (95% CI 151 to 255 million), to the British population. Per capita exposure was around 5 times higher for alcohol than for tobacco, and nearly 4 times higher in adolescents, who were exposed to an average of 52.1 (95% CI 43.4 to 60.9) and 10.5 (95% CI 8.8 to 12.3) alcohol and tobacco impressions, respectively, than in adults (14.1 (95% CI 10.2 to 18.1) and 2.9 (95% CI 2.1 to 3.6)). Exposure rates were higher in girls than in boys. YouTube music videos deliver millions of gross impressions of alcohol and tobacco content. Adolescents are exposed much more than adults. Music videos are a major global medium of exposure to such content. Published by the BMJ Publishing Group Limited.

Objective Conduct a social media content analysis of COPD patient education videos on YouTube. Methods A systematic search protocol was used to locate 223 videos. Two independent coders evaluated each video to determine topics covered, media source(s) of posted videos, information quality as measured by HONcode guidelines for posting trustworthy health information on the Internet, and viewer exposure/engagement metrics. Results Over half the videos (n=113, 50.7%) included information on medication management, with far fewer videos on smoking cessation (n=40, 17.9%). Most videos were posted by a health agency or organization (n=128, 57.4%), and the majority of videos were rated as high quality (n=154, 69.1%). HONcode adherence differed by media source (Fisher’s Exact Test=20.52, p=.01), with user-generated content (UGC) receiving the lowest quality scores. Overall level of user engagement as measured by number of “likes,” “favorites,” “dislikes,” and user comments was low (mdn range = 0–3, interquartile (IQR) range = 0–16) across all sources of media. Conclusion Study findings suggest that COPD education via YouTube has the potential to reach and inform patients, however, existing video content and quality varies significantly. Future interventions should help direct individuals with COPD to increase their engagement with high-quality patient education videos on YouTube that are posted by reputable health organizations and qualified medical professionals. Patients should be educated to avoid and/or critically view low-quality videos posted by individual YouTube users who are not health professionals. PMID:24659212

2014-01-01

Introduction A major outbreak of West Nile Virus was seen last year in different parts of the United States. Adequate dissemination of correct information about the disease would have helped decrease its spread and the associated panic in the general population. In this study, we looked into the use of YouTube as a resource for providing information about West Nile Virus infection. Objective This study aims to identify and evaluate YouTube as resource for providing information on West Nile Virus infection to the general public. Methods YouTube was searched on November 25, 2012, using the keywords West Nile Virus epidemic, West Nile Virus infection, and West Nile Virus prevention for videos uploaded in the past 6 months containing relevant information about the disease. The videos were classified as useful, misleading, or as news updates based on the type of information contained. Total viewership, number of days since upload, total duration of videos, and source of upload were noted. Results A total of 106 videos with information on West Nile Virus infection were included in the study, with 79.24% having useful information about the disease. Among the useful videos, 51/84 (60.71%) had information on disease prevention, and 29/84 (34.52%) contained information on news and research updates. The majority of these videos were uploaded by individuals (54.6%) or news agencies (41.8 %). Healthcare agencies contributed only 3.4 % of the total videos. Even though the useful videos represented 72% of all videos, there was significantly higher total viewership and viewership per day for the non-useful videos (P<0.05). Conclusions YouTube may be a significant resource for dissemination of information on public health issues like West Nile virus infection and should be targeted by healthcare agencies for this use. The major drawback of this medium is lack of verification by authorized healthcare professionals before these videos are made available for viewing by the community

2017-12-01

Since the satellite era began, NASA has collected a large volume of Earth science observations for research and applications around the world. Satellite data at 12 NASA data centers can also be used for STEM activities such as disaster events, climate change, etc. However, accessing satellite data can be a daunting task for non-professional users such as teachers and students because of unfamiliarity of terminology, disciplines, data formats, data structures, computing resources, processing software, programing languages, etc. Over the years, many efforts have been developed to improve satellite data access, but barriers still exist for non-professionals. In this presentation, we will present our latest activity that uses the popular online video sharing web site, YouTube, to access visualization of global precipitation datasets at the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC). With YouTube, users can access and visualize a large volume of satellite data without necessity to learn new software or download data. The dataset in this activity is the 3-hourly TRMM (Tropical Rainfall Measuring Mission) Multi-satellite Precipitation Analysis (TMPA). The video consists of over 50,000 data files collected since 1998 onwards, covering a zone between 50°N-S. The YouTube video will last 36 minutes for the entire dataset record (over 19 years). Since the time stamp is on each frame of the video, users can begin at any time by dragging the time progress bar. This precipitation animation will allow viewing precipitation events and processes (e.g., hurricanes, fronts, atmospheric rivers, etc.) on a global scale. The next plan is to develop a similar animation for the GPM (Global Precipitation Measurement) Integrated Multi-satellitE Retrievals for GPM (IMERG). The IMERG provides precipitation on a near-global (60°N-S) coverage at half-hourly time interval, showing more details on precipitation processes and development, compared to the 3

YouTube is the most popular video sharing website, and is increasingly used to broadcast health information including smoking cessation advice. This study examines the quality and quantity of YouTube quit smoking videos targeted at people living with mental illness (MI). We systematically searched YouTube using selected relevant search terms. The first 50 videos obtained for each search term were screened for relevance and further videos screened through snowball sampling. Forty unique, English language videos focussing on people with MI were included in the assessment and evaluated for general video characteristics, themes, format, targeted smoking cessation and harm reduction information. Most videos either discussed the problem of high smoking rates among people with MI (n=12) or smoking cessation programmes and policies at an institutional level (n=13). Only nine videos were aimed at providing quit smoking advice to this population. One video recommended higher doses of nicotine replacement therapy (NRT) for people with MI while six videos referred to possible changes in medication dosage on quitting smoking. Four videos suggested cutting down smoking for harm reduction. Very few YouTube videos specifically focus on the problem of high smoking rates among people with MI and even fewer provide targeted smoking cessation and harm reduction advice for this priority population. There is a need to develop comprehensive, evidence based, quit smoking video resources for smokers with a MI. Published by the BMJ Publishing Group Limited.

Social media Web sites such as YouTube offer activists unique opportunities to reach out to new audiences through a variety of diverse appeals. Yet the rules of engagement on social media should depend on the structures, goals, and characteristics of the movements engaging in this outreach. To explore how differences in social movements translate into online activism, we employ a paired case study approach, comparing YouTube artifacts for two political mobilizations: the Occupy Movement and California's Proposition 8 ballot initiative concerning same sex marriage. Across movements, we examine the popularity of videos and their characteristics, and whether the type of video consistently predicts video engagement. We find that "social media activism" is not a unitary phenomenon; the two mobilizations produced unique YouTube ecologies. Occupy Wall Street videos tended on average to produce less engagement and focused on filmed live events and amateur content. Meanwhile, Proposition 8 videos usually produced more engagement and bridged more diverse formats: from professionalized and scripted content to live event footage and unscripted monologues to the camera. Therefore, our study suggests that social activism in online spaces such as YouTube is not easily defined, but is adapted to suit movement needs-which makes social media a popular and flexible venue for activism but also highlights the challenges for scholars studying such venues.

YouTube as a potential learning tool to help distinguish tonic-clonic seizures from nonepileptic attacks.

2014-08-01

Medical students are increasingly turning to the website YouTube as a learning resource. This study set out to determine whether the videos on YouTube accurately depict the type of seizures that a medical student may search for. Two consultant epileptologists independently assessed the top YouTube videos returned following searches for eight terms relating to different categories of seizures. The videos were rated for their technical quality, concordance of diagnosis with an epileptologist-assigned diagnosis, and efficacy as a learning tool for medical education. Of the 200 videos assessed, 106 (63%) met the inclusion criteria for further analysis. Technical quality was generally good and only interfered with the diagnostic process in 8.5% of the videos. Of the included videos, 40.6-46.2% were judged to depict the purported diagnosis with moderate agreement between raters (75% agreement, κ=0.50). Of the videos returned after searching "tonic-clonic seizure", 28.6-35.7% were judged to show nonepileptic seizures with almost perfect interrater agreement (92.9% agreement, κ=0.84). Of the videos returned following the search "pseudoseizure", 77.8-88.9% of videos were judged to show nonepileptic seizures with substantial agreement (88.9% agreement, κ=0.61). Across all search terms, 19.8-33% of videos were judged as potentially useful as a learning resource, with fair agreement between raters (75.5% agreement, κ=0.38). These findings suggest that the majority of videos on YouTube claiming to show specific seizure subtypes are inaccurate, and YouTube should not be recommended as a learning tool for students. However, a small group of videos provides excellent demonstrations of tonic-clonic and nonepileptic seizures, which could be used by an expert teacher to demonstrate the difference between epileptic and nonepileptic seizures.

Urethral catheterization (UC) is a common procedure carried out on a daily basis. The aims of this study were to assess the quality of YouTube as an educational tool regarding male UC and to assess the experience of newly qualified doctors regarding UC. YouTube was searched for videos containing relevant information about male UC. A checklist for evaluating content for male UC was devised. The top-ranked video was shown to interns and they were questioned regarding their experience of UC and the usefulness of the video. A total of 100 videos was screened and 49 unique videos were identified. The median length of video was 7 min 15 s (range 1 min 44 s to 26 min 44 s). Regarding the Safe Catheter Insertion Score, the mean score was 5.18 ± 1.64. 9 (18.4%) deemed useful, 24 (49%) somewhat useful and 16 (32.7%) not useful. There was no difference in the number of views (p = 0.487), duration of video (p = 0.364) or number of days online (p = 0.123) between those categorized as useful, somewhat useful and not useful. Twenty-six interns (89.7%) attended the UC teaching session. All reported the video to be a useful educational adjunct. Nine of the respondents (42.9%) had independently inserted a urinary catheter before the educational session. The quality of videos on YouTube regarding male UC is widely variable. Preselected videos are deemed useful by junior doctors regarding male UC and can be used as an educational adjunct before performing hands-on tasks.

The outreach of YouTube may have a dramatic role in the widespread dissemination of knowledge on implantable cardioverter devices (ICD). This study was designed to review and analyze the information available on YouTube pertaining to implantable cardiac devices such as implantable cardioverter defibrillators (ICDs) and pacemakers. YouTube was queried for the terms "ICD", "Implantable Cardioverter Defibrillator", and "Pacemaker". The videos were reviewed and categorized as according to content; number of views and "likes" or "dislikes" was recorded by two separate observers. Of the 55 videos reviewed, 18 of the videos were categorized as patient education, 12 were advertisements, 8 were intraoperative videos documenting the device implantation procedures, 7 of the videos were produced to document personal patient experiences, and 4 were categorized as documentation of a public event. 3 were intended to educate health care workers. The remaining 3 were intended to raise public awareness about sudden cardiac death. The videos portraying intraoperative procedures generated the most "likes" or "dislikes" per view. While YouTube provides a logical platform for delivery of health information, the information on this platform is not regulated. Initiative by reputed authorities and posting accurate information in such platform can be a great aid in public education regarding device therapy.

2014-01-01

Assess the overall quality of information on adenotonsillectomy and ear tube surgery presented on YouTube (www.youtube.com) from the perspective of a parent or patient searching for information on surgery. The YouTube website was systematically searched on select dates with a formal search strategy to identify videos pertaining to pediatric adenotonsillectomy and ear tube surgery. Only videos with at least 5 (ear tube surgery) or 10 (adenotonsillectomy) views per day were included. Each video was viewed and scored by two independent scorers. Videos were categorized by goal and scored for video/audio quality, accuracy, comprehensiveness, and procedure-specific content. Cross-sectional study. Public domain website. Fifty-five videos were scored for adenotonsillectomy and forty-seven for ear tube surgery. The most common category was educational (65.3%) followed by testimonial (28.4%), and news program (9.8%). Testimonials were more common for adenotonsillectomy than ear tube surgery (41.8% vs. 12.8%, p=0.001). Testimonials had a significantly lower mean accuracy (2.23 vs. 2.62, p=0.02), comprehensiveness (1.71 vs. 2.22, p=0.007), and TA specific content (0.64 vs. 1.69, p=0.001) score than educational type videos. Only six videos (5.9%) received high scores in both video/audio quality and accuracy/comprehensiveness of content. There was no significant association between the accuracy and comprehensive score and views, posted "likes", posted "dislikes", and likes/dislikes ratio. There was an association between "likes" and mean video quality (Spearman's rho=0.262, p=0.008). Parents/patients searching YouTube for information on pediatric adenotonsillectomy and ear tube surgery will generally encounter low quality information with testimonials being common but of significantly lower quality. Viewer perceived quality ("likes") did not correlate to formally scored content quality. Published by Elsevier Ireland Ltd.

YouTube as a Site of Counternarratives to Transnormativity.

PubMed

Miller, Jordan F

2018-06-12

In this article, I discuss how transnormativity can be disrupted by not exaggerating the physical aspects of medical transition and by engaging in conversations around consequential sources of tension within gender and sexual minority communities, namely linguistic understandings of trans and gendered racism within white, gay cisgender communities toward trans communities of color. This study is based on qualitative interviews with six trans YouTubers; these interviews were complemented by analyses of these YouTubers' videos and select comments on these videos. With this exploratory study, I aim to provide nuance to existing lesbian, gay, bisexual and trans (LGBT) YouTube literature through highlighting the experiences of non-binary trans vloggers and trans vloggers of color, regardless of medical transition status, as well as contribute a transfeminist analysis to ongoing conversations around transnormativity within sociology, cultural and media studies, and queer and trans theory.

Gynecologic Cancer Information on YouTube: Will Women Watch Advertisements to Learn More?

2015-01-01

The quality and accuracy of health content posted on YouTube varies widely. To increase dissemination of evidence-based gynecologic cancer information to US YouTube users, the Centers for Disease Control and Prevention (CDC) sponsored two types of advertisements: (1) pre-roll videos that users had to watch for at least 5 s before seeing a video they selected and (2) keyword-targeted listings that appeared in search results when users entered terms related to gynecologic cancer. From July 2012 to November 2013, pre-roll videos were shown 9.2 million times, viewed (watched longer than the mandatory 5 s) 1.6 million times (17.6%), and cost $0.09 per view. Keyword-targeted listings were displayed 15.3 million times, viewed (activated by users) 59,766 times (0.4%), and cost $0.31 per view. CDC videos in advertisements played completely in 17.0% of pre-roll video views and 44.4% of keyword-targeted listing views. Advertisements on YouTube can disseminate evidence-based cancer information broadly with minimal cost. PMID:25877466

For the first time in 50 years, traffic fatalities have increased in the United States (US). With the emergence of technology, comes the possibility, that distracted driving has contributed to a decrease in safe driving practices. The purpose of this study was to describe the content on the popular video sharing site, YouTube to ascertain the type of content conveyed in videos that are widely viewed. The 100 most widely viewed English language videos were included in this sample, with a collective number of views of over 35 million. The majority of videos were television-based and Internet-based. Pairwise comparisons indicated that there were statistically significant differences between the number of views of consumer generated videos and television-based videos (p = 0.001) and between television-based videos and Internet-based videos (p < 0.001). Compared with consumer generated videos, television-based videos were 13 times more likely to discuss cell phone use as a distractor while driving, while Internet-based videos were 6.6 times more likely to discuss cell phone use as a distractor while driving. In addition, compared with consumer generated videos, television-based videos were 3.67 times more likely to discuss texting as a distractor while driving, whereas Internet-based videos were 8.5 times more likely to discuss texting as a distractor while driving. The findings of this study indicate that the videos on YouTube related to distracted driving are popular and that this medium could prove to be a successful venue to communicate information about this emergent public health issue.

YouTube as a Potential Training Resource for Laparoscopic Fundoplication.

Frongia, Giovanni; Mehrabi, Arianeb; Fonouni, Hamidreza; Rennert, Helga; Golriz, Mohammad; Günther, Patrick

To analyze the surgical proficiency and educational quality of YouTube videos demonstrating laparoscopic fundoplication (LF). In this cross-sectional study, a search was performed on YouTube for videos demonstrating the LF procedure. The surgical and educational proficiency was evaluated using the objective component rating scale, the educational quality rating score, and total video quality score. Statistical significance was determined by analysis of variance, receiver operating characteristic curve, and odds ratio analysis. A total of 71 videos were included in the study; 28 (39.4%) videos were evaluated as good, 23 (32.4%) were moderate, and 20 (28.2%) were poor. Good-rated videos were significantly longer (good, 22.0 ± 5.2min; moderate, 7.8 ± 0.9min; poor, 8.5 ± 1.0min; p = 0.007) and video duration was predictive of good quality (AUC, 0.672 ± 0.067; 95% CI: 0.541-0.802; p = 0.015). For good quality, the cut-off video duration was 7:42 minute. This cut-off value had a sensitivity of 67.9%, a specificity of 60.5%, and an odds ratio of 3.23 (95% CI: 1.19-8.79; p = 0.022) in predicting good quality. Videos uploaded from industrial sources and with a higher views/days online ratio had a higher objective component rating scale and total video quality score. In contrast, the likes/dislikes ratio was not predictive of video quality. Many videos showing the LF procedure have been uploaded to YouTube with varying degrees of quality. A process for filtering LF videos with high surgical and educational quality is feasible by evaluating the video duration, uploading source, and the views/days online ratio. However, alternative videos platforms aimed at professionals should also be considered for educational purposes. Copyright © 2016 Association of Program Directors in Surgery.

2018-06-01

Skin bleaching is a common, yet potentially harmful body modification practice. To describe the characteristics of the most widely viewed YouTube™ videos related to skin bleaching. The search term 'skin bleaching' was used to identify the 100 most popular English-language YouTube videos relating to the topic. Both descriptive and specific information were noted. Among the 100 manually coded skin-bleaching YouTube videos in English, there were 21 consumer-created videos, 45 internet-based news videos, 30 television news videos and 4 professional videos. Excluding the 4 professional videos, we limited our content categorization and regression analysis to 96 videos. Approximately 93% (89/96) of the most widely viewed videos mentioned changing how you look and 74% (71/96) focused on bleaching the whole body. Of the 96 videos, 63 (66%) of videos showed/mentioned a transformation. Only about 14% (13/96) mentioned that skin bleaching is unsafe. The likelihood of a video selling a skin bleaching product was 17 times higher in internet videos compared with consumer videos (OR = 17.00, 95% CI 4.58-63.09, P < 0.001). Consumer-generated videos were about seven times more likely to mention making bleaching products at home compared with internet-based news videos (OR = 6.86, 95% CI 1.77-26.59, P < 0.01). The most viewed YouTube video on skin bleaching was uploaded by an internet source. Videos made by television sources mentioned more information about skin bleaching being unsafe, while consumer-generated videos focused more on making skin-bleaching products at home. © 2017 British Association of Dermatologists.

YouTube is increasingly becoming a key source for people to satisfy the need for additional information concerning their medical condition. This study analyses the completeness of accurate information found on YouTube pertaining to hip arthritis. The present study analyzed 133 YouTube videos using the search terms: hip arthritis, hip arthritis symptoms, hip arthritis diagnosis, hip arthritis treatment and hip replacement. Two quality assessment checklists with a scale of 0 to 12 points were developed to evaluate available video content for the diagnosis and the treatment of hip arthritis. Videos were grouped into poor quality (grade 0-3), moderate quality (grade 4-7) and excellent quality (grade 8-12), respectively. Three independent observers assessed all videos using the new grading system and independently scored all videos. Discrepancies regarding the categories were clarified by consensus discussion. For intra-observer reliabilities, grading was performed at two occasions separated by four weeks. Eighty-four percent (n = 112) had a poor diagnostic information quality, 14% (n = 19) a moderate quality and only 2% (n = 2) an excellent quality, respectively. In 86% (n = 114), videos provided poor treatment information quality. Eleven percent (n = 15) of videos had a moderate quality and only 3% (n = 4) an excellent quality, respectively. The present study demonstrates that YouTube is a poor source for accurate information pertaining to the diagnosis and treatment of hip arthritis. These finding are of high relevance for clinicians as videos are going to become the primary source of information for patients. Therefore, high quality educational videos are needed to further guide patients on the way from the diagnosis of hip arthritis to its proper treatment.

2015-01-01

Background We aimed to characterize the content of leading YouTube videos related to alcohol intoxication and to examine factors associated with alcohol intoxication in videos that were assessed positively by viewers. Methods We systematically captured the 70 most relevant and popular videos on YouTube related to alcohol intoxication. We employed an iterative process to codebook development which resulted in 42 codes in 6 categories: video characteristics, character socio-demographics, alcohol depiction, degree of alcohol use, characteristics associated with alcohol, and consequences of alcohol. Results There were a total of 333,246,875 views for all videos combined. While 89% of videos involved males, only 49% involved females. The videos had a median of 1646 (IQR 300-22,969) “like” designations and 33 (IQR 14-1,261) “dislike” designations each. Liquor was most frequently represented, followed by beer and then wine/champagne. Nearly one-half (44%) of videos contained a brand reference. Humor was juxtaposed with alcohol use in 79% of videos, and motor vehicle use was present in 24%. There were significantly more likes per dislike, indicating more positive sentiment, when there was representation of liquor (29.1 vs. 11.4, p = .008), brand references (32.1 vs. 19.2, p = .04), and/or physical attractiveness (67.5 vs. 17.8, p < .001). Conclusions Internet videos depicting alcohol intoxication are heavily viewed. Nearly half of these videos involve a brand-name reference. While these videos commonly juxtapose alcohol intoxication with characteristics such as humor and attractiveness, they infrequently depict negative clinical outcomes. The popularity of this site may provide an opportunity for public health intervention. PMID:25703135

2017-09-01

We characterized leading YouTube videos featuring alcohol brand references and examined video characteristics associated with each brand and video category. We systematically captured the 137 most relevant and popular videos on YouTube portraying alcohol brands that are popular among underage youth. We used an iterative process to codebook development. We coded variables within domains of video type, character sociodemographics, production quality, and negative and positive associations with alcohol use. All variables were double coded, and Cohen's kappa was greater than .80 for all variables except age, which was eliminated. There were 96,860,936 combined views for all videos. The most common video type was "traditional advertisements," which comprised 40% of videos. Of the videos, 20% were "guides" and 10% focused on chugging a bottle of distilled spirits. While 95% of videos featured males, 40% featured females. Alcohol intoxication was present in 19% of videos. Aggression, addiction, and injuries were uncommonly identified (2%, 3%, and 4%, respectively), but 47% of videos contained humor. Traditional advertisements represented the majority of videos related to Bud Light (83%) but only 18% of Grey Goose and 8% of Hennessy videos. Intoxication was most present in chugging demonstrations (77%), whereas addiction was only portrayed in music videos (22%). Videos containing humor ranged from 11% for music-related videos to 77% for traditional advertisements. YouTube videos depicting the alcohol brands favored by underage youth are heavily viewed, and the majority are traditional or narrative advertisements. Understanding characteristics associated with different brands and video categories may aid in intervention development.

2017-07-01

Since the internet has become an important source of contraceptive information with YouTube.com as the second most visited site, we analysed contraceptive implant YouTube videos for content and clinical accuracy. Using the terms 'contraceptive implant', 'Nexplanon' and 'Implanon', the top 20 results on YouTube by relevance and view count were identified. After excluding duplicates, single-rod implant videos in English were included. Videos were classified as providing a professional or patient perspective. Views, duration and comments were noted. Videos were rated for reliability, global quality scale and whether they were positive or negative about the implant. Inter-rater agreement was measured. A total of 120 videos were retrieved; 52 were eligible for review. Less than 23% were professional videos; the majority reported patient experience (46% testimonials, 27% real-time procedure videos, 4% other). Patient videos had been posted a significantly longer duration of time than professional videos (364 vs 188 days, p =0.02), were less reliable ( p ≤0.0001) and were of lower global quality ( p <0.0001). Some 61% of implant testimonial videos were rated as 'positive experiences' and inter-rater agreement was very good (κ=0.81). All testimonials mentioned side effects, commonly irregular bleeding and discomfort with insertion. A minority (26%) reported misinformation. This study found that most of the information on YouTube pertaining to contraceptive implants is accurate, is presented from the patient's perspective, and promotes the method's use.

Towards Assisted Moderation in Online Healthcare Social Networks: Improving Trust in YouTube Searches.

PubMed

Cañon, Daniel E; Lopez, Diego M; Blobel, Bernd

2014-01-01

Moderation of content in online Health Social Networks (HSN) is critical because information is not only published and produced by experts or health professionals, but also by users of that information. The objective of this paper is to propose a semi-automatic moderation Web Service for assessing the quality (trustworthiness) of health-related videos published on the YouTube social network. The service is relevant for moderators or community managers, who get enabled to control the quality of videos published on their online HSN sites. The HealthTrust metric was selected as the metric to be implemented in the service in order to support the assessment of trustworthiness of videos in Online HSN. The service is a RESTful service which can be integrated into open source Virtual Social Network Platforms, therefore improving trust in the process of searching and publishing content extracted from YouTube. A preliminary pilot evaluation in a simple use case demonstrated that the relevance of videos retrieved using the moderation service was higher compared to the relevance of the videos retrieved using the YouTube search engine.

'How to stop a nosebleed': an assessment of the quality of epistaxis treatment advice on YouTube.

Haymes, A T; Harries, V

2016-08-01

Video hosting websites are increasingly being used to disseminate health education messages. This study aimed to assess the quality of advice contained within YouTube videos on the conservative management of epistaxis. YouTube.com was searched using the phrase 'how to stop a nosebleed'. The first 50 videos were screened. Objective advice scores and subjective production quality scores were attributed by independent raters. Forty-five videos were analysed. The mean advice score was 2.0 out of 8 and the mean production quality score was 1.6 out of 3. There were no correlations between a video's advice score and its search results rank (ρ = -0.28, p = 0.068), its view count (ρ = 0.20, p = 0.19) or its number of 'likes' (ρ = 0.21, p = 0.18). The quality of information on conservative epistaxis management within YouTube videos is extremely variable. A high search rank is no indication of video quality. Many videos proffer inappropriate and dangerous 'alternative' advice. We do not recommend YouTube as a source for patient information.

Anatomy remains a cornerstone of medical education despite challenges that have seen a significant reduction in contact hours over recent decades; however, the rise of the "YouTube Generation" or "Generation Connected" (Gen C), offers new possibilities for anatomy education. Gen C, which consists of 80% Millennials, actively interact with social media and integrate it into their education experience. Most are willing to merge their online presence with their degree programs by engaging with course materials and sharing their knowledge freely using these platforms. This integration of social media into undergraduate learning, and the attitudes and mindset of Gen C, who routinely creates and publishes blogs, podcasts, and videos online, has changed traditional learning approaches and the student/teacher relationship. To gauge this, second year undergraduate medical and radiation therapy students (n = 73) were surveyed regarding their use of online social media in relation to anatomy learning. The vast majority of students had employed web-based platforms to source information with 78% using YouTube as their primary source of anatomy-related video clips. These findings suggest that the academic anatomy community may find value in the integration of social media into blended learning approaches in anatomy programs. This will ensure continued connection with the YouTube generation of students while also allowing for academic and ethical oversight regarding the use of online video clips whose provenance may not otherwise be known. © 2015 American Association of Anatomists.

Driver sleepiness on YouTube: A content analysis.

Hawkins, A N; Filtness, A J

2017-02-01

Driver sleepiness is a major contributor to severe crashes and fatalities on our roads. Many people continue to drive despite being aware of feeling tired. Prevention relies heavily on education campaigns as it is difficult to police driver sleepiness. The video sharing social media site YouTube is extremely popular, particularly with at risk driver demographics. Content and popularity of uploaded videos can provide insight into the quality of publicly accessible driver sleepiness information. The purpose of this research was to answer two questions; firstly, how prevalent are driver sleepiness videos on YouTube? And secondly, what are the general characteristics of driver sleepiness videos in terms of (a) outlook on driver sleepiness, (b) tone, (c) countermeasures to driver sleepiness, and, (d) driver demographics. Using a keywords search, 442 relevant videos were found from a five year period (2nd December 2009-2nd December 2014). Tone, outlook, and countermeasure use were thematically coded. Driver demographic and video popularity data also were recorded. The majority of videos portrayed driver sleepiness as dangerous. However, videos that had an outlook towards driver sleepiness being amusing were viewed more often and had more mean per video comments and likes. Humorous videos regardless of outlook, were most popular. Most information regarding countermeasures to deal with driver sleepiness was accurate. Worryingly, 39.8% of videos with countermeasure information contained some kind of ineffective countermeasure. The use of humour to convey messages about the dangers of driver sleepiness may be a useful approach in educational interventions. Copyright © 2015 Elsevier Ltd. All rights reserved.

The aim of the present study is to conduct a social media content analysis of chronic obstructive pulmonary disease (COPD) patient education videos on YouTube. A systematic search protocol was used to locate 223 videos. Two independent coders evaluated each video to determine topics covered, media source(s) of posted videos, information quality as measured by HONcode guidelines for posting trustworthy health information on the Internet, and viewer exposure/engagement metrics. Over half the videos (n = 113, 50.7%) included information on medication management, with far fewer videos on smoking cessation (n = 40, 17.9%). Most videos were posted by a health agency or organization (n = 128, 57.4%), and the majority of videos were rated as high quality (n = 154, 69.1%). HONcode adherence differed by media source (Fisher's exact test = 20.52, p = 0.01), however with user-generated content receiving the lowest quality scores. Overall level of user engagement as measured by number of "likes," "favorites," "dislikes," and user comments was low (median range = 0-3, interquartile range = 0-16) across all sources of media. Study findings suggest that COPD education via YouTube has the potential to reach and inform patients; however, existing video content and quality varies significantly. Future interventions should help direct individuals with COPD to engage with high-quality patient education videos on YouTube that are posted by reputable health organizations and qualified medical professionals. Patients should be educated to avoid and/or critically view low-quality videos posted by individual YouTube users who are not health professionals.

The YouTube Makeup Class

NASA Astrophysics Data System (ADS)

Haase, David G.

2009-05-01

When a college instructor goes out of town and must miss a lecture, the standard options are to cancel the class meeting or to enlist a colleague to fill in. In the former case a teaching opportunity is lost; in the latter the substitute may not lead the class in the same way as the instructor. Some students routinely skip lectures by a guest instructor, in the belief that the material in the substitute lecture will not be covered on the exam. There are other makeup options such as a directed study assignment. For instance, a missed class is sometimes a good opportunity to require students to investigate web-based simulations such as Physlets® that illustrate the class topics. These are most effective if the students are given a clear structure and if there are questions that the students must answer from their investigations with the Physlets. But many students are more comfortable with the audio and visual communication that occurs in the classroom. Web 2.0 technology, e.g., YouTube (http://www.youtube.com), makes it convenient for faculty to upload videos of lectures and demonstrations that can be used for makeup classes. College students already use YouTube for entertainment, and the YouTube format is simple to view on any web-connected computer. Although some universities have highly developed media delivery systems, YouTube is extremely convenient and accessible by anyone. This paper discusses how a YouTube makeup class can be efficiently produced and structured to be an effective learning experience.

We aimed to characterize the content of leading YouTube videos related to alcohol intoxication and to examine factors associated with alcohol intoxication in videos that were assessed positively by viewers. We systematically captured the 70 most relevant and popular videos on YouTube related to alcohol intoxication. We employed an iterative process to codebook development which resulted in 42 codes in 6 categories: video characteristics, character socio demographics, alcohol depiction, degree of alcohol use, characteristics associated with alcohol, and consequences of alcohol. There were a total of 333,246,875 views for all videos combined. While 89% of videos involved males, only 49% involved females. The videos had a median of 1,646 (interquartile range [IQR] 300 to 22,969) "like" designations and 33 (IQR 14 to 1,261) "dislike" designations each. Liquor was most frequently represented, followed by beer and then wine/champagne. Nearly one-half (44%) of videos contained a brand reference. Humor was juxtaposed with alcohol use in 79% of videos, and motor vehicle use was present in 24%. There were significantly more likes per dislike, indicating more positive sentiment, when there was representation of liquor (29.1 vs. 11.4, p = 0.008), brand references (32.1 vs. 19.2, p = 0.04), and/or physical attractiveness (67.5 vs. 17.8, p < 0.001). Internet videos depicting alcohol intoxication are heavily viewed. Nearly, half of these videos involve a brand-name reference. While these videos commonly juxtapose alcohol intoxication with characteristics such as humor and attractiveness, they infrequently depict negative clinical outcomes. The popularity of this site may provide an opportunity for public health intervention. Copyright © 2015 by the Research Society on Alcoholism.

The aim of this study was to assess the contents of medical textbooks, eMedicine (Medscape) topics, and YouTube videos on cardiovascular mechanisms. Medical textbooks, eMedicine articles, and YouTube were searched for cardiovascular mechanisms. Using appraisal forms, copies of these resources and videos were evaluated independently by three assessors. Most textbooks were brief in explaining mechanisms. Although the overall average percentage committed to cardiovascular mechanisms in physiology textbooks (n=7) was 16.1% and pathology textbooks (n=4) was 17.5%, there was less emphasis on mechanisms in most internal medicine textbooks (n=6), with a total average of 6.9%. In addition, flow diagrams explaining mechanisms were lacking. However, eMedicine topics (n=48) discussed mechanisms adequately in 22.9% (11 of 48) topics, and the percentage of content allocated to cardiovascular mechanisms was higher (15.8%, 46.2 of 292) compared with that of any internal medicine textbooks. Only 29 YouTube videos fulfilled the inclusion criteria. Of these, 16 YouTube were educationally useful, scoring 14.1 ± 0.5 (mean ± SD). The remaining 13 videos were not educationally useful, scoring 6.1 ± 1.7. The concordance between the assessors on applying the criteria measured by κ score was in the range of 0.55–0.96. In conclusion, despite the importance of mechanisms, most textbooks and You-Tube videos were deficient in cardiovascular mechanisms. eMedicine topics discussed cardiovascular mechanisms for some diseases, but there were no flow diagrams or multimedia explaining mechanisms. These deficiencies in learning resources could add to the challenges faced by students in understanding cardiovascular mechanisms.

2016-01-01

Collecting large datasets of amputee gait data is notoriously difficult. Additionally, collecting data on less prevalent amputations or on gait activities other than level walking and running on hard surfaces is rarely attempted. However, with the wealth of user-generated content on the Internet, the scope for collecting amputee gait data from alternative sources other than traditional gait labs is intriguing. Here we investigate the potential of YouTube videos to provide gait data on amputee walking. We use an example dataset of trans-femoral amputees level walking at self-selected speeds to collect temporal gait parameters and calculate gait asymmetry. We compare our YouTube data with typical literature values, and show that our methodology produces results that are highly comparable to data collected in a traditional manner. The similarity between the results of our novel methodology and literature values lends confidence to our technique. Nevertheless, clear challenges with the collection and interpretation of crowd-sourced gait data remain, including long term access to datasets, and a lack of validity and reliability studies in this area.

2017-01-01

Since the satellite era began, NASA has collected a large volume of Earth science observations for research and applications around the world. The collected and archived satellite data at 12 NASA data centers can also be used for STEM education and activities such as disaster events, climate change, etc. However, accessing satellite data can be a daunting task for non-professional users such as teachers and students because of unfamiliarity of terminology, disciplines, data formats, data structures, computing resources, processing software, programming languages, etc. Over the years, many efforts including tools, training classes, and tutorials have been developed to improve satellite data access for users, but barriers still exist for non-professionals. In this presentation, we will present our latest activity that uses a very popular online video sharing Web site, YouTube (https://www.youtube.com/), for accessing visualizations of our global precipitation datasets at the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC). With YouTube, users can access and visualize a large volume of satellite data without the necessity to learn new software or download data. The dataset in this activity is a one-month animation for the GPM (Global Precipitation Measurement) Integrated Multi-satellite Retrievals for GPM (IMERG). IMERG provides precipitation on a near-global (60 deg. N-S) coverage at half-hourly time interval, providing more details on precipitation processes and development compared to the 3-hourly TRMM (Tropical Rainfall Measuring Mission) Multisatellite Precipitation Analysis (TMPA, 3B42) product. When the retro-processing of IMERG during the TRMM era is finished in 2018, the entire video will contain more than 330,000 files and will last 3.6 hours. Future plans include development of flyover videos for orbital data for an entire satellite mission or project. All videos, including the one-month animation, will be uploaded and

YouTube is a global medium used predominantly by young adults (aged 18-49 years). This study examined the quality of YouTube information regarding ACL injury and reconstruction. YouTube was searched on the 13th of June 2015 for "ACL" and "anterior cruciate ligament" with/without associated terms of "injury", "reconstruction", and "surgery". Videos were evaluated by two independent reviewers [EF (Reviewer 1), (Reviewer 2)] using two recognized information scoring systems (Modified DISCERN (MD) 0-5 and JAMA Benchmark 0-4) and an adaptation of a score designed for written ACL information [ACL Specific Score (ASS) 0-25]. The ASS categorized scores as very good (21-25), good (16-20), moderate (11-15), poor (6-10), and very poor (0-5). Number of views/likes/dislikes, animation, and continent of origin and source (e.g., corporate/educational) were recorded. Correlation of video characteristics with number of views was examined using the analysis of variance (ANOVA) model. Agreement between reviewers was assessed by Interclass Correlation Co-efficient (ICC). Following a filtering process of the 964,770 identified videos, 39 videos were retained. The mean MD score was 2.3 (standard deviation (SD) ±0.9) for Reviewer 1 and 2.2 (SD ±0.9) for Reviewer 2 (ICC = 0.7). The mean JAMA score was 2.5(SD ±0.7) for Reviewer 1 and 2.3 (SD ±0.7) for Reviewer 2 (ICC = 0.8). The mean ASS was 6.3 (SD ±3.5) for Reviewer 1 and 4.6 (SD ±2.9) for Reviewer 2 (ICC = 0.9). Five videos achieved moderate score (13%), while 15 (38%) and 19 (49%) scored as poor and very poor, respectively. There was no correlation between number of views and video quality/video source for any scoring system. The majority of videos viewed on YouTube regarding ACL injury and treatment are of low quality.

The importance of videos in social media communications in the context of health care and neurosurgery is becoming increasingly recognized. However, there has not yet been a systematic analysis of these neurosurgery-related communications. Accordingly, this study was aimed at characterizing the online video content pertaining to neurosurgery. Neurosurgery-related videos uploaded on YouTube were collected using a comprehensive search strategy. The following metrics were extracted for each video: number of views, likes, dislikes, comments, shares, date of upload, and geographic region of origin where specified. A quantitative and qualitative evaluation was performed on all videos included in the study. A total of 713 nonduplicate videos met the inclusion criteria. The overall number of views for all videos was 90,545,164. Videos were most frequently uploaded in 2016 (n = 348), with a 200% increase in uploads compared with the previous year. Of the videos that were directly relevant to clinical neurosurgery, the most frequent video categories were "educational videos" (25%), followed by "surgical and procedure overview" (20%), "promotional videos" (17%), and "patient experience" (16%). The remainder of the videos consisted primarily of unrealistic simulations of cranial surgery for entertainment purposes (20%). The findings from this study highlight the increasing use of video communications related to neurosurgery and show that institutions, neurosurgeons, and patients are using YouTube as an educational and promotional platform. As online communications continue to evolve, it will be important to harness this tool to advance patient-oriented communication and knowledge dissemination in neurosurgery.

2013-06-01

Background and aims Nearly half of all patients with inflammatory bowel disease (IBD) use the Internet as a source of information for their disease. We analyzed the source, content and accuracy of IBD videos found on YouTube - one of the most popular websites in the United States - and assessed the demographic variables of the viewers. The 100 most viewed videos with relevant information on IBD were analyzed. We included only English language videos that were less than 20 min in length and primarily focused on IBD. Those with no sound/poor sound quality were excluded. More than 30 variables were analyzed. Adults of 45-54 years old (95.1%) comprised the most common age group of viewers. Forty-eight percent of videos focused on Crohn's disease (CD), 32.0% on ulcerative colitis (UC), and 20.0% on both. Overall content for patient education was poor. Videos discussing alternative treatment options were more likely to depict patients' personal experience (73.9% vs. 2.4%) (p<0.001) and be an advertisement compared to patient education videos (78.3% vs. 0) (p<0.001). Videos discussing patient education had a higher number of favorites (mean 25.0 vs. 5.5) (p<0.001), comments (mean 22.0 vs. 5.0) (p<0.022) and "likes" (mean 19.0 vs. 9.0) (p=0.025) than the ones discussing alternative treatment options. YouTube videos on IBD are popular but a poor source of patient education. Healthcare providers and professional societies should provide more educational materials using this powerful Internet tool to counteract the misleading information, especially for the targeted age group (45-54 years).

Choking, cutting, and setting oneself on fire are just a few of the risky behaviors that the YouTube video sharing website has allowed youth around the world to view, emulate, and comment on. Some researchers contend that the viewing of videos may normalize these behaviors for youth. Disturbing current trends are explored to illustrate the darker side of YouTube. Psychiatric-mental health nurses (PMHNs) are in key positions to help parents and youth better understand the benefits and risks of social networking sites, including YouTube, and to encourage healthy and safe use of the Internet. Nursing implications are offered for PMHNs, educators, health care providers, and parents who have contact with this population. Copyright 2015, SLACK Incorporated.

2017-09-01

Background No work has been reported on the use of video websites to learn about deep vein thrombosis and the value of education using them. We examined the characteristics and scientific accuracy of videos related to deep vein thrombosis on YouTube. Methods YouTube was surveyed using no filter and the key words 'deep vein thrombosis' and 'leg vein clot' in June 2016. The videos evaluated were divided into three groups in terms of their scientific content, accuracy, and currency: useful, partly useful, and useless. Results Of the 1200 videos watched, 715 (59.58%) were excluded with the exclusion criteria. Although most of the videos uploaded (22.9%, n = 111) were created by physicians, the number of views for website-based videos was significantly higher (p = 0.002). When the uploaded videos were assessed in terms of their usefulness, videos from physicians and hospitals were statistically more useful than other videos (p < 0.001). Conclusions For videos created by medical professionals to be of higher quality, we believe they should be more up-to-date and comprehensive, and contain animations about treatment modalities and early diagnosis in particular.

Social media as YouTube have become a part of daily life and many studies evaluated health-related YouTube videos. Our aim was to evaluate videos available on YouTube for the conformity to textbook information and their sufficiency as a source for patient information. A search of the YouTube website was performed using the keywords "spinal anesthesia, epidural anesthesia, combined spinal epidural anesthesia". Firstly, 180 videos were evaluated and the characteristics of the video were noted, and the features of the video too were noted if the video was regarding neuraxial anesthesia. Questionnaire 1 (Q1) evaluating the video quality relating to neuraxial anesthesia was designed using a textbook as reference and questionnaire 2 (Q2) was designed for evaluating patient information. After exclusions, 40 videos were included in the study. There was no difference in Q1 or Q2 scores when videos were grouped into 4 quarters according to their appearance order, time since upload or views to length rate (p>0.05). There was no statistical difference between Q1 or Q2 scores for spinal, epidural or combined videos (p>0.05). Videos prepared by a healthcare institute have a higher score in both Questionnaires 1 and 2 (10.87±4.28 vs. 5.84±2.90, p=0.044 and 3.89±5.43 vs. 1.19±3.35, p=0.01 respectively). Videos prepared by institutes, societies, etc. were of higher educational value, but were still very lacking. Videos should be prepared in adherence to available and up-to-date guidelines taking into consideration appropriate step by step explanation of each procedure, patient safety and frequently asked questions.

2015-01-01

Using a sample of YouTube videos posted on the YouTube channels of organ procurement organizations, a content analysis was conducted to identify the frames used to strategically communicate prodonation messages. A total of 377 videos were coded for general characteristics, format, speaker characteristics, organs discussed, structure, problem definition, and treatment. Principal components analysis identified message frames, and k-means cluster analysis established distinct groupings of videos on the basis of the strength of their relationship to message frames. Analysis of these frames and clusters found that organ procurement organizations present multiple, and sometimes competing, video types and message frames on YouTube. This study serves as important formative research that will inform future studies to measure the effectiveness of the distinct message frames and clusters identified.

Food allergy affects an estimated 8% of children and 3% of adults in the United States. Food-allergic individuals increasingly use the web for medical information. We sought to determine the educational quality of food allergy YouTube videos. We performed a YouTube search using keywords "food allergy" and "food allergies". The 300 most viewed videos were included and analyzed for characteristics, source, and content. Source was further classified as healthcare provider, alternative medicine provider, patient, company, media, and professional society. A scoring system (FA-DQS) was created to evaluate quality (-10 to +34 points). Negative points were assigned for misleading information. Eight reviewers scored each video independently. Three hundred videos were analyzed, with a median of 6351.50 views, 19 likes, and 1 dislike. More video presenters were female (54.3%). The most common type of video source was alternative medicine provider (26.3%). Alternative treatments included the following: water fast, juicing, Ayurveda, apple cider, yoga, visualization, and sea moss. Controversial diagnostics included kinesiology, IgG testing, and pulse test. Almost half of the videos depicted a non-IgE-mediated reaction (49.0%).Videos by professional societies had the highest FA-DQS (7.27). Scores for videos by professional societies were significantly different from other sources (P < .001). There was a high degree of agreement among reviewers (ICC = 0.820; P < .001). YouTube videos on food allergy frequently recommend controversial diagnostics and commonly depict non-IgE-mediated reactions. There is a need for high-quality, evidence-based, educational videos on food allergy. © 2018 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Common Femoral Artery Access on YouTube: What Practices are Being Shown and Who is Delivering the Message?

PubMed

Pitcher, Grayson S; Newton, Daniel H; Amendola, Michael F

Novice learners are increasingly turning to YouTube as a learning resource for surgical procedures. One example of such a procedure is common femoral artery puncture and sheath placement. Practitioners in several specialties perform this procedure to access the arterial system for angiography and intervention. We set forth to compare the techniques demonstrated on YouTube by the various specialists, as well as compare each specialty׳s prevalence on this website. YouTube (www.youtube.com) was accessed in December 2015 at multiple time points with a cleared-cache web browser for the keyword search categories: "femoral artery access," "femoral access," and "angiography access." The top 500 videos from each of these keyword searches were analyzed. Videos were categorized by practitioner specialty, technique, duration of video, age of video, and total views. Videos with clear demonstration of femoral artery access were included in the analysis. All industry videos were excluded from the analysis. Categorical variables were compared using Fisher׳s exact test, and continuous variables were compared with the Student׳s t-test. A total of 2460, 4680 and 1800 videos were found for each keyword search, respectively. Of these, 33 videos clearly demonstrated femoral artery access technique. Vascular specialists, compared to interventional cardiology and radiology, had fewer videos (n = 4 vs. 14) and older videos (3.5 ± 2.1y vs. 2.25 ± 0.5y, p < 0.05). The vascular specialists demonstrated ultrasound-guided access, while interventional cardiology predominantly demonstrated landmark-guided access (p < 0.05). Although YouTube and other online resources are being used by novice learners, vascular specialists are underrepresented for femoral artery access, a foundational vascular procedure. Other practitioners demonstrate videos with landmark-guided access and rarely demonstrate ultrasound use. As recognized vascular experts, vascular surgeons should improve their visibility in

In this paper, an embedded system for remote online video monitoring was designed and developed to capture and record the real-time circumstances in elevator. For the purpose of improving the efficiency of video acquisition and processing, the system selected Samsung S5PV210 chip as the core processor which Integrated graphics processing unit. And the video was encoded with H.264 format for storage and transmission efficiently. Based on S5PV210 chip, the hardware video coding technology was researched, which was more efficient than software coding. After running test, it had been proved that the hardware video coding technology could obviously reduce the cost of system and obtain the more smooth video display. It can be widely applied for the security supervision [1].

The image of you: constructing nursing identities in YouTube.

PubMed

Kelly, Jacinta; Fealy, Gerard M; Watson, Roger

2012-08-01

This article is a report on a descriptive study of nursing identity as constructed in the Web 2.0 site YouTube. Public images of the nurse carry stereotypes that rely on the taken for granted gender category of the nurse as woman. Nursing images represent a form of public discourse that has the capacity to construct nursing identity. Critical discourse analysis was used to describe, analyse and explain how nurse and nursing identity were constructed in a purposive sample of ten video clips accessed on 17 and 18 July 2010. The ten most-viewed videos depicting the nurse and nursing on YouTube offered narratives that constructed three distinct nursing identity types, namely nurse as 'a skilled knower and doer', nurse as 'a sexual plaything' and nurse as 'a witless incompetent' individual. Nursing identities recoverable from the texts of YouTube images propagate both favourable and derogatory nursing stereotypes. To mitigate the effects of unfavourable nursing stereotypes in such areas as interprofessional working and clinical decision-making, nursing professional bodies need to act to protect the profession from unduly immoderate representations of the nurse and to support nurses in their efforts to maximize opportunities afforded by YouTube to promote a counter discourse. © 2011 Blackwell Publishing Ltd.

2016-04-18

With declining reimbursement to health care systems, face-to-face time between patients and providers to optimize preoperative education and counseling may be challenging. Because high patient anxiety prior to surgery has been linked to more severe and persistent pain after joint replacement surgery, the Orthopedic Surgery Department at Mayo Clinic in Florida created a playlist of 16 YouTube videos aimed at creating a virtual hospital experience for primary total hip and knee joint replacement patients. A randomized trial was then performed to evaluate the potential impact of viewing this playlist on preoperative anxiety. Each patient completed a Generalized Anxiety Disorder (GAD) score assessment at the time of the routine preoperative clinic visit and then randomized based on his/her gender, type of surgery, and initial GAD score to either the control group of standard education (education at face-to-face clinical visits as well as printed educational materials) or the treatment group (standard education plus access to the YouTube playlist). On the morning of the patient's surgery, the same survey was repeated. Of the 65 patients who consented to participate in the study, 53 completed the study (82%) with 28 of 29 (97% completed) in the control group and 25 of 36 (69% completed) in the treatment group. Overall, the results showed a trend toward less anxiety in patients who viewed the YouTube videos; this was exhibited by a reduction in the median GAD score by 1 point. This trend is more clearly present in patients with high preoperative anxiety (predominantly women), as seen in the reduction of the median GAD score by 6 points in the treatment group. Although our experience is limited, our results indicate that a series of tailored videos may decrease patient anxiety preoperatively. We recommend further exploration of both this concept and the use of social media tools in preoperative patient education. Clinicaltrials.gov NCT02546180; http

Scholars, educators, and students are increasingly encouraged to participate in online spaces. While the current literature highlights the potential positive outcomes of such participation, little research exists on the sentiment that these individuals may face online and on the factors that may lead some people to face different types of sentiment than others. To investigate these issues, we examined the strength of positive and negative sentiment expressed in response to TEDx and TED-Ed talks posted on YouTube (n = 655), the effect of several variables on comment and reply sentiment (n = 774,939), and the projected effects that sentiment-based moderation would have had on posted content. We found that most comments and replies were neutral in nature and some topics were more likely than others to elicit positive or negative sentiment. Videos of male presenters showed greater neutrality, while videos of female presenters saw significantly greater positive and negative polarity in replies. Animations neutralized both the negativity and positivity of replies at a very high rate. Gender and video format influenced the sentiment of replies and not just the initial comments that were directed toward the video. Finally, we found that using sentiment as a way to moderate offensive content would have a significant effect on non-offensive content. These findings have far-reaching implications for social media platforms and for those who encourage or prepare students and scholars to participate online.

Video imagery acquired with underwater vehicles is an essential tool for characterizing seafloor ecosystems and seafloor geology. It is a fundamental component of ocean exploration that facilitates real-time operations, augments multidisciplinary scientific research, and holds tremendous potential for public outreach and engagement. Acquiring, documenting, managing, preserving and providing access to large volumes of video acquired with underwater vehicles presents a variety of data stewardship challenges to the oceanographic community. As a result, only a fraction of underwater video content collected with research submersibles is documented, discoverable and/or viewable online. With more than 1 billion users, YouTube offers infrastructure that can be leveraged to help address some of the challenges associated with sharing underwater video with a broad global audience. Anyone can post content to YouTube, and some oceanographic organizations, such as the Schmidt Ocean Institute, have begun live-streaming video directly from underwater vehicles. OceanVideoLab (oceanvideolab.org) was developed to help improve access to underwater video through simple annotation, browse functionality, and integration with related environmental data. Any underwater video that is publicly accessible on YouTube can be registered with OceanVideoLab by simply providing a URL. It is strongly recommended that a navigational file also be supplied to enable geo-referencing of observations. Once a video is registered, it can be viewed and annotated using a simple user interface that integrates observations with vehicle navigation data if provided. This interface includes an interactive map and a list of previous annotations that allows users to jump to times of specific observations in the video. Future enhancements to OceanVideoLab will include the deployment of a search interface, the development of an application program interface (API) that will drive the search and enable querying of

How to freak a Black & Mild: a multi-study analysis of YouTube videos illustrating cigar product modification.

2014-02-01

Cigar smoking is increasingly common among adolescents who perceive cigars as less harmful than cigarettes. This perception of reduced harm is especially true for cigars that are user-modified by removing the tobacco binder through a process called 'freaking'. Little is known about 'freaking' and this multi-study, mixed-methods analysis sought to understand better the rationale and prevailing beliefs about this smoking practice using YouTube videos. In Study 1, we conducted a descriptive content analysis on the characteristics of 26 randomly sampled cigar product modification (CPM) videos posted during 2006-10. In Study 2, a thematic analysis was performed on the transcripts of commentary associated with each video to characterize viewers' comments about video content. Study 1 results revealed that 90% of videos illustrated a four-step CPM technique: 'Loosening the tobacco'; 'Dumping the tobacco'; 'Removing the cigar binder' and 'Repacking the tobacco'. Four themes related to the purpose of CPM were also derived from video content: 'Easier to smoke' (54%), 'Beliefs in reduction of health risks' (31%), 'Changing the burn rate' (15%) and 'Taste enhancement' (12%). Study 2 results concerning the content characteristics of video comments were categorized into three themes: 'Disseminating information/answering questions' (81%), 'Seeking advice/asking questions' (69%) and 'Learning cigar modification techniques' (35%). Favorable comments were more common (81%) compared to unfavorable (58%) and comment content suggested low-risk perceptions and poor understanding of smoking harms. These findings highlight a novel means for youth to access information concerning CPM that may have important implications for tobacco control policy and prevention.

YouTube as a tool for pain management with informal caregivers of cancer patients: a systematic review.

2014-12-01

Cancer caregivers have information and support needs, especially about cancer pain management. With high Internet use reported among caregivers, YouTube may be an accessible option when looking for information on cancer pain management. The purpose of this study was to explore the availability and characteristics of instructional cancer pain management videos on YouTube and determine to what extent these videos addressed the role of informal caregivers in cancer pain management. A systematic review of videos on YouTube resulting from search terms "pain and cancer," "pain and hospice," and "pain and palliative care" was conducted in May 2013. If the video addressed pain management, was in English, and was instructional, it was coded for the scope and design of instructional content that included caregivers. The search terms yielded 1118 unique videos, and 43 videos met the inclusion criteria. Overall, 63% of videos were viewed 500 times or less, and half of the videos received "like" ratings by viewers. Video instruction was primarily talk without any onscreen action (65%), user-generated amateur video (79%), and had poor quality sources of information. Videos were mainly clinician centered (77%). Although most videos addressed the need for caregiver pain assessment (35%) and caregiver education (23%), few actually addressed specific caregiver pain management barriers. Most videos were primarily directed toward a clinical audience. Future research is necessary to determine if the platform is feasible and beneficial as a support tool for oncology caregivers.

Youtube for millennial nursing students; using internet technology to support student engagement with bioscience.

PubMed

Johnston, Amy Nb; Barton, Matthew J; Williams-Pritchard, Grant A; Todorovic, Michael

2018-06-09

Undergraduate nursing programs typically include students with limited 'on-campus' time who need learning resources that are flexible, technologically appropriate, remotely-accessible (mobile smart devices), and above all, engaging. This has presented academics with challenges surrounding institutional security firewalls, password-access requirements, intellectual property/ownership and staff/student privacy. To overcome these challenges a collection of evidence-based YouTube videos, posted on the Biological Sciences YouTube Channel, supported by the Biosciences in Nurse Education, and underpinned by Benner's pedagogical framework, were developed with the intention of moving students from novice to competent clinical bioscience users. The videos are highly successful; with over 310,000 views, 1.5 million minutes of viewing and more than 5000 subscribers since its inception (<20 months). Spontaneous comments as well as evidence from students identified their usefulness, suggesting the videos enrich student experience and performance with perceivably difficult biosciences content. Student confidence and subsequent access of the YouTube videos was enhanced by their familiarity with the presenter and the breadth of information available in small portions, creating a solid basis for the development of bioscience-competent nursing graduates. Moreover, these open source videos provide a free resource for continual revision and professional development informed by an international minimum bioscience standard for nurses post registration.

Connecting world youth with tobacco brands: YouTube and the internet policy vacuum on Web 2.0.

PubMed

Elkin, Lucy; Thomson, George; Wilson, Nick

2010-10-01

The internet is an ideal forum for tobacco marketing, as it is largely unregulated and there is no global governing body for controlling content. Nevertheless, tobacco companies deny advertising on the internet. To assess the extent and nature of English language videos available on the Web 2.0 domain 'YouTube' that contain tobacco brand images or words. The authors conducted a YouTube search using five leading non-Chinese cigarette brands worldwide. The themes and content of up to 40 of the most viewed videos returned for each search were analysed: a total of 163 videos. A majority of the 163 tobacco brand-related videos analysed (71.2%, 95% CI 63.9 to 77.7) had pro-tobacco content, versus a small minority (3.7%) having anti-tobacco content (95% CI 1.4 to 7.8). Most of these videos contained tobacco brand content (70.6%), the brand name in the title (71.2%) or smoking imagery content (50.9%). One pro-smoking music video had been viewed over 2 million times. The four most prominent themes of the videos were celebrity/movies, sports, music and 'archive', the first three of which represent themes of interest to a youth audience. Pro-tobacco videos have a significant presence on YouTube, consistent with indirect marketing activity by tobacco companies or their proxies. Since content may be removed from YouTube if it is found to breach copyright or if it contains offensive material, there is scope for the public and health organisations to request the removal of pro-tobacco content containing copyright or offensive material. Governments should also consider implementing Framework Convention on Tobacco Control requirements on the internet, to further reduce such pro-tobacco content.

Enabling MPEG-2 video playback in embedded systems through improved data cache efficiency

NASA Astrophysics Data System (ADS)

Soderquist, Peter; Leeser, Miriam E.

1999-01-01

Digital video decoding, enabled by the MPEG-2 Video standard, is an important future application for embedded systems, particularly PDAs and other information appliances. Many such system require portability and wireless communication capabilities, and thus face severe limitations in size and power consumption. This places a premium on integration and efficiency, and favors software solutions for video functionality over specialized hardware. The processors in most embedded system currently lack the computational power needed to perform video decoding, but a related and equally important problem is the required data bandwidth, and the need to cost-effectively insure adequate data supply. MPEG data sets are very large, and generate significant amounts of excess memory traffic for standard data caches, up to 100 times the amount required for decoding. Meanwhile, cost and power limitations restrict cache sizes in embedded systems. Some systems, including many media processors, eliminate caches in favor of memories under direct, painstaking software control in the manner of digital signal processors. Yet MPEG data has locality which caches can exploit if properly optimized, providing fast, flexible, and automatic data supply. We propose a set of enhancements which target the specific needs of the heterogeneous types within the MPEG decoder working set. These optimizations significantly improve the efficiency of small caches, reducing cache-memory traffic by almost 70 percent, and can make an enhanced 4 KB cache perform better than a standard 1 MB cache. This performance improvement can enable high-resolution, full frame rate video playback in cheaper, smaller system than woudl otherwise be possible.

Evaluating YouTube as a Source of Patient Education on the Role of the Hospitalist: A Cross-Sectional Study

Background Hospital medicine is a relatively new specialty field, dedicated to the delivery of comprehensive medical care to hospitalized patients. YouTube is one of the most frequently used websites, offering access to a gamut of videos from self-produced to professionally made. Objective The aim of our study was to determine the adequacy of YouTube as an effective means to define and depict the role of hospitalists. Methods YouTube was searched on November 17, 2014, using the following search words: “hospitalist,” “hospitalist definition,” “what is the role of a hospitalist,” “define hospitalist,” and “who is a hospitalist.” Videos found only in the first 10 pages of each search were included. Non-English, noneducational, and nonrelevant videos were excluded. A novel 7-point scoring tool was created by the authors based on the definition of a hospitalist adopted by the Society of Hospital Medicine. Three independent reviewers evaluated, scored, and classified the videos into high, intermediate, and low quality based on the average score. Results A total of 102 videos out of 855 were identified as relevant and included in the analysis. Videos uploaded by academic institutions had the highest mean score. Only 6 videos were classified as high quality, 53 as intermediate quality, and 42 as low quality, with 82.4% (84/102) of the videos scoring an average of 4 or less. Conclusions Most videos found in the search of a hospitalist definition are inadequate. Leading medical organizations and academic institutions should consider producing and uploading quality videos to YouTube to help patients and their families better understand the roles and definition of the hospitalist.

Veenstra, Aaron S; Park, Chang Sup; Lyons, Benjamin A; Kang, Cheeyoun Stephanie; Iyer, Narayanan

2015-07-01

As digital media technologies have evolved and become more powerful, the prevalence of mixed-media content-that is, content that mixes multiple media such as text and video-has increased considerably. Perhaps nowhere is this more apparent than YouTube, now the Web's third most trafficked site. YouTube provides for video sharing in an environment otherwise dominated by textual titles, descriptions, and comments. As such, it is an ideal venue in which to examine the impact of intramedium interaction on message evaluation. This study uses a survey experiment to test first-person and third-person evaluations of campaign ads from the Obama and Romney campaigns, and the comments posted about them on YouTube, using two real ads and one set of fake comments. Findings suggest that partisan perceptions of the manipulated ads transfer to the constant comments, and that the contextual cue of the YouTube environment reciprocally impacts partisan evaluation of the ads themselves.

2014-02-01

Breast cancer patient's expectation and choice of reconstruction is increasing and patients often satisfy their information needs outside clinic time by searching the world wide web. The aim of our study was to analyse the quality of content and extent of information regarding breast reconstruction available on YouTube videos and whether this is an appropriate additional source of information for patients. A snapshot qualitative and quantitative analysis of the first 100 videos was performed after the term 'breast reconstruction' was input into the search window of the video sharing website www.youtube.com on the 1st of September 2011. Qualitative categorical analysis included patient, oncological and reconstruction factors. It was concluded that although videos uploaded onto YouTube do not provide comprehensive information, it is a useful resource that can be utilised in patient education provided comprehensive and validated videos are made available.

This study details an innovative and methodical content analysis of 2,207 YouTube comments from four different YouTube videos (e.g., breaking news or memorials) related to the 2012 Sandy Hook Elementary School and Aurora theater mass shootings and the catastrophic Hurricane Sandy. As expected, YouTube comments associated with the Sandy Hook shootings (particularly those from a memorial video) were especially likely to feature compassion and grief with lessened hostility. This study highlights differing online contexts by which individuals show grief and related emotions following man-made and natural calamities and how-even in an online environment-powerful situational contexts greatly guide behavior.

Youth access, creation, and content of smokeless tobacco ("dip") videos in social media.

Seidenberg, Andrew B; Rodgers, Elizabeth J; Rees, Vaughan W; Connolly, Gregory N

2012-04-01

Smokeless tobacco (SLT) use among white adolescent males has increased in recent years, and prevalence of SLT use among adolescent males exceeds that for smoking in several U.S. states. Recent reports have described the presence of cigarette-related content on social media Web sites popular among youth; however, little has been reported on SLT content. The YouTube video search engine was searched for the popular SLT brand Skoal, and the first 50 search results were downloaded. Video statistics data were collected for and content analysis was performed on all videos featuring smokeless use (82%). Access to SLT YouTube videos by youth was also determined by assessing whether YouTube permits youth viewing and creation of SLT videos. Mean number of views for videos analyzed was 15,422, and the most watched video had 124,276 views. Descriptions of SLT flavor/smell and social references/interactions were found in 48.8% and 63.4% of videos, respectively. By contrast, references to drug (nicotine) effects (12.2%) and public health messaging (9.8%) were less common. None of the SLT videos in the sample had restrictions that would block youth viewing. In addition, evidence of self-identified youth creating SLT videos was found for 13% of unique users in the sample. YouTube does not restrict youth from creating or viewing "dip videos." Proactive efforts are needed to ensure that YouTube and other online media do not become influential vehicles for tobacco promotion to youth.

m-YouTube Mobile UI: Video Selection Based on Social Influence

NASA Astrophysics Data System (ADS)

Marcus, Aaron; Perez, Angel

The ease-of-use of Web-based video-publishing services provided by applications like YouTube has encouraged a new means of asynchronous communication, in which users can post videos not only to make them public for review and criticism, but also as a way to express moods, feelings, or intentions to an ever-growing network of friends. Following the current trend of porting Web applications onto mobile platforms, the authors sought to explore user-interface design issues of a mobile-device-based YouTube, which they call m-YouTube. They first analyzed the elements of success of the current YouTube Web site and observed its functionality. Then, they looked for unsolved issues that could give benefit through information-visualization design for small screens on mobile phones to explore a mobile version of such a product/service. The biggest challenge was to reduce the number of functions and amount information to fit into a mobile phone screen, but still be usable, useful, and appealing within the YouTube context of use and user experience. Borrowing ideas from social research in the area of social influence processes, they made design decisions aiming to help YouTube users to make the decision of what video content to watch and to increase the chances of YouTube authors being evaluated and observed by peers. The paper proposes a means to visualize large amounts of video relevant to YouTube users by using their friendship network as a relevance indicator to help in the decision-making process.

YouTube: a new way of supplementing traditional methods in dental education.

Mukhopadhyay, Sanjana; Kruger, Estie; Tennant, Marc

2014-11-01

Higher education in many disciplines has undergone a dramatic change with the incorporation of electronic means to enhance student learning. YouTube is an open-access online website that has gained tremendous popularity in recent years as it allows users to upload videos for social and educational purposes. The aim of this study was to assess whether dentally relevant videos would be utilized as a freely available tool to aid learning. Forty videos, mainly in the area of dental anatomy and local anesthesia, were uploaded and made available for a period of eighteen months from March 2012 to September 2013. The videos were watched a total of nearly 71,000 times, with the anatomy channels accounting for 58,000 views. Most of the viewers were from the United States and Australia, with an ever-increasing number of viewers from developing countries. This study suggests that YouTube can be used as an adjunct tool to supplement dental education due to it being easily accessible online. It provides many sources of information that can be accessed by those working in or preparing for the dental profession, whether students, practitioners, or those in geographically isolated areas.

PubMed

Addar, Abdullah; Marwan, Yousef; Algarni, Nizar; Berry, Gregory

Distal radius fractures (DRFs) are the most common orthopedic fractures, with >70% of cases treated by closed immobilization using a short arm cast or a sugar tong splint. However, inadequate immobilization is a risk factor for loss of reduction requiring repeat reduction or surgical treatment. Therefore, education of clinical skills for appropriate immobilization of DRFs is important. With the increasing use of web-based information by medical learners, our aim was to assess the quality and quantity of videos regarding closed immobilization of DRFs on YouTube. Retrospective review of YouTube videos on distal radius fracture immobilization using specific search terms. Identified videos were analyzed for their educational value, quality of the technical skill demonstrated, and overall metrics. Educational value was scored on a 5-point scale, with "1" indicative of low quality and "5" of high quality. Not applicable. Among the 68,366 videos identified, 16 met our inclusion criteria of being in English; performed by a health care professional or institution; and with casting being the major theme of the educational information provided. Of these 16 videos, 6 had an educational value score of 4 or 5, with the remaining 10 having a score ≤3. Although immobilization was demonstrated by cast technician specialized in orthopedics, skills were also performed by orthopedic attendants, urgent care physicians, orthopedic residents, and nurse practitioners. The credentials of the performer in 3 videos were not identified. There is a need to promote high-quality educational videos produced by established medical school faculty members on open, web-based, portals.

Too many crying babies: a systematic review of pain management practices during immunizations on YouTube

PubMed Central

2014-01-01

Background Early childhood immunizations, although vital for preventative health, are painful and too often lead to fear of needles. Effective pain management strategies during infant immunizations include breastfeeding, sweet solutions, and upright front-to-front holding. However, it is unknown how often these strategies are used in clinical practice. We aimed to review the content of YouTube videos showing infants being immunized to ascertain parents’ and health care professionals’ use of pain management strategies, as well as to assess infants’ pain and distress. Methods A systematic review of YouTube videos showing intramuscular injections in infants less than 12 months was completed using the search terms "baby injection" and "baby vaccine" to assess (1) the use of pain management strategies and (2) infant pain and distress. Pain was assessed by crying duration and pain scores using the FLACC (Face, Legs, Activity, Cry, Consolability) tool. Results A total of 142 videos were included and coded by two trained individual viewers. Most infants received one injection (range of one to six). Almost all (94%) infants cried before or during the injections for a median of 33 seconds (IQR = 39), up to 146 seconds. FLACC scores during the immunizations were high, with a median of 10 (IQR = 3). No videos showed breastfeeding or the use of sucrose/sweet solutions during the injection(s), and only four (3%) videos showed the infants being held in a front-to-front position during the injections. Distraction using talking or singing was the most commonly used (66%) pain management strategy. Conclusions YouTube videos of infants being immunized showed that infants were highly distressed during the procedures. There was no use of breastfeeding or sweet solutions and limited use of upright or front-to-front holding during the injections. This systematic review will be used as a baseline to evaluate the impact of future knowledge translation interventions using

Exploring the explaining quality of physics online explanatory videos

Kulgemeyer, Christoph; Peters, Cord H.

2016-11-01

Explaining skills are among the most important skills educators possess. Those skills have also been researched in recent years. During the same period, another medium has additionally emerged and become a popular source of information for learners: online explanatory videos, chiefly from the online video sharing website YouTube. Their content and explaining quality remain to this day mostly unmonitored, as well is their educational impact in formal contexts such as schools or universities. In this study, a framework for explaining quality, which has emerged from surveying explaining skills in expert-novice face-to-face dialogues, was used to explore the explaining quality of such videos (36 YouTube explanatory videos on Kepler’s laws and 15 videos on Newton’s third law). The framework consists of 45 categories derived from physics education research that deal with explanation techniques. YouTube provides its own ‘quality measures’ based on surface features including ‘likes’, views, and comments for each video. The question is whether or not these measures provide valid information for educators and students if they have to decide which video to use. We compared the explaining quality with those measures. Our results suggest that there is a correlation between explaining quality and only one of these measures: the number of content-related comments.

A Secure and Robust Compressed Domain Video Steganography for Intra- and Inter-Frames Using Embedding-Based Byte Differencing (EBBD) Scheme

2016-01-01

This paper presents a novel secure and robust steganographic technique in the compressed video domain namely embedding-based byte differencing (EBBD). Unlike most of the current video steganographic techniques which take into account only the intra frames for data embedding, the proposed EBBD technique aims to hide information in both intra and inter frames. The information is embedded into a compressed video by simultaneously manipulating the quantized AC coefficients (AC-QTCs) of luminance components of the frames during MPEG-2 encoding process. Later, during the decoding process, the embedded information can be detected and extracted completely. Furthermore, the EBBD basically deals with two security concepts: data encryption and data concealing. Hence, during the embedding process, secret data is encrypted using the simplified data encryption standard (S-DES) algorithm to provide better security to the implemented system. The security of the method lies in selecting candidate AC-QTCs within each non-overlapping 8 × 8 sub-block using a pseudo random key. Basic performance of this steganographic technique verified through experiments on various existing MPEG-2 encoded videos over a wide range of embedded payload rates. Overall, the experimental results verify the excellent performance of the proposed EBBD with a better trade-off in terms of imperceptibility and payload, as compared with previous techniques while at the same time ensuring minimal bitrate increase and negligible degradation of PSNR values.

Social media are becoming mainstream in the health domain. Despite the large volume of accurate and trustworthy health information available on social media platforms, finding good-quality health information can be difficult. Misleading health information can often be popular (eg, antivaccination videos) and therefore highly rated by general search engines. We believe that community wisdom about the quality of health information can be harnessed to help create tools for retrieving good-quality social media content. To explore approaches for extracting metrics about authoritativeness in online health communities and how these metrics positively correlate with the quality of the content. We designed a metric, called HealthTrust, that estimates the trustworthiness of social media content (eg, blog posts or videos) in a health community. The HealthTrust metric calculates reputation in an online health community based on link analysis. We used the metric to retrieve YouTube videos and channels about diabetes. In two different experiments, health consumers provided 427 ratings of 17 videos and professionals gave 162 ratings of 23 videos. In addition, two professionals reviewed 30 diabetes channels. HealthTrust may be used for retrieving online videos on diabetes, since it performed better than YouTube Search in most cases. Overall, of 20 potential channels, HealthTrust's filtering allowed only 3 bad channels (15%) versus 8 (40%) on the YouTube list. Misleading and graphic videos (eg, featuring amputations) were more commonly found by YouTube Search than by searches based on HealthTrust. However, some videos from trusted sources had low HealthTrust scores, mostly from general health content providers, and therefore not highly connected in the diabetes community. When comparing video ratings from our reviewers, we found that HealthTrust achieved a positive and statistically significant correlation with professionals (Pearson r₁₀ = .65, P = .02) and a trend toward

Searching for pelvic floor muscle exercises on YouTube: what individuals may find and where this might fit with health service programmes to promote continence.

PubMed

Stephen, Kate; Cumming, Grant P

2012-09-01

This paper describes the investigation, categorization/characterization and viewing of pelvic floor muscle exercises (PFME) on YouTube from the perspective of the 'wisdom of the crowd'. The aim of the research was to increase awareness of the type of clips that individuals are likely to come across when searching YouTube and to describe trends and popularity. This awareness will be useful for the design of continence promotion services, especially for hard-to-reach individuals. Web-based videos relating to PFE were identified by searching YouTube using the snowball technique. Main outcome measures Number of views; the approach taken (health, fitness, sexual and pregnancy); product promotion; and the use of music, visual cues and elements designed to encourage exercise. The number of views of each video was recorded at three points over a seven-month period. Twenty-two videos were identified. Overall these videos had been viewed over 430,000 times during the study period. One video was viewed over 100,000 times and overall the median increase in views was 59.4%. YouTube is increasingly used to access information about pelvic floor exercises. Different approaches are used to communicate PFME information but there are no formal structures for quality control. Further research is required to identify which elements of the video clips are effective in communicating information and in motivating exercise and to establish appropriate protocols. Kitemarking is recommended in order that women obtain correct advice.

Hussin, Mallory; Frazier, Savannah; Thompson, J Kevin

2011-01-01

YouTube.com is an internet website that is viewed by two billion individuals daily, and thus may serve as the source of images and messages regarding weight acceptance or weight bias. In the current study, a targeted sample of YouTube videos that displayed fat stigmatization were content rated on a variety of video characteristics. The findings revealed that men were the target of fat stigmatization (62.1%) almost twice as often as women (36.4%). When there was an antagonist present in the video, the great majority of the time, the aggressor was male (88.5%) rather than female (7.7%). These findings indicate that men were the antagonist 11.5 times the rate of women, but they were only 1.7 times more often stigmatized. Future research avenues, including an experimental analysis of viewing stigmatizing videos on body image, are recommended. Copyright © 2010 Elsevier Ltd. All rights reserved.

YouTube as a crowd-generated water level archive.

In view of the substantial costs associated with classic monitoring networks, participatory data collection methods can be deemed a promising option to obtain complementary data. An emerging trend in this field is social media mining, i.e., harvesting of pre-existing, crowd-generated data from social media. Although this approach is participatory in a broader sense, the users are mostly not aware of their participation in research. Inspired by this novel development, we demonstrate in this study that it is possible to derive a water level time series from the analysis of multiple YouTube videos. As an example, we studied the recent water level rise in Dahl Hith, a Saudi Arabian cave. To do so, we screened 16 YouTube videos of the cave for suitable reference points (e.g., cave graffiti). Then, we visually estimated the distances between these points and the water level and traced their changes over time. To bridge YouTube hiatuses, we considered own photos taken during two site visits. For the time period 2013-2014, we estimate a rise of 9.5m. The fact that this rise occurred at a somewhat constant rate of roughly 0.4m per month points towards a new and permanent water source, possibly two nearby lakes formed from treated sewage effluent. An anomaly in the rising rate is noted for autumn 2013 (1.3m per month). As this increased pace coincides with a cluster of rain events, we deem rapid groundwater recharge along preferential flow paths a likely cause. Despite the sacrifice in precision, we believe that YouTube harvesting may represent a viable option to gather historical water levels in data-scarce settings and that it could be adapted to other environments (e.g., flood extents). In certain areas, it might provide an additional tool for the monitoring toolbox, thereby possibly delivering hydrological data for water resources management. Copyright © 2016 Elsevier B.V.

Biel, Joan-Isaac; Gatica-Perez, Daniel

While existing studies on YouTube's massive user-generated video content have mostly focused on the analysis of videos, their characteristics, and network properties, little attention has been paid to the analysis of users' long-term behavior as it relates to the roles they self-define and (explicitly or not) play in the site. In this chapter, we present a statistical analysis of aggregated user behavior in YouTube from the perspective of user categories, a feature that allows people to ascribe to popular roles and to potentially reach certain communities. Using a sample of 270,000 users, we found that a high level of interaction and participation is concentrated on a relatively small, yet significant, group of users, following recognizable patterns of personal and social involvement. Based on our analysis, we also show that by using simple behavioral features from user profiles, people can be automatically classified according to their category with accuracy rates of up to 73%.

The Internet, and its popularity, continues to grow at an unprecedented pace. Watching videos online is very popular; it is estimated that 500 h of video are uploaded onto YouTube, a video-sharing service, every minute and that, by 2019, video formats will comprise more than 80% of Internet traffic. Health-related videos are very popular on YouTube, but their quality is always a matter of concern. One approach to enhancing the quality of online videos is to provide additional educational health content, such as websites, to support health consumers. This study investigates the feasibility of building a content-based recommender system that links health consumers to reputable health educational websites from MedlinePlus for a given health video from YouTube. The dataset for this study includes a collection of health-related videos and their available metadata. Semantic technologies (such as SNOMED-CT and Bio-ontology) were used to recommend health websites from MedlinePlus. A total of 26 healths professionals participated in evaluating 253 recommended links for a total of 53 videos about general health, hypertension, or diabetes. The relevance of the recommended health websites from MedlinePlus to the videos was measured using information retrieval metrics such as the normalized discounted cumulative gain and precision at K. The majority of websites recommended by our system for health videos were relevant, based on ratings by health professionals. The normalized discounted cumulative gain was between 46% and 90% for the different topics. Our study demonstrates the feasibility of using a semantic content-based recommender system to enrich YouTube health videos. Evaluation with end-users, in addition to healthcare professionals, will be required to identify the acceptance of these recommendations in a nonsimulated information-seeking context.

Background: YouTube is the second most commonly accessed website worldwide, but little is known about the accuracy of its medical content. We performed a review to analyze the type and quality of content in a YouTube search with respect to the treatment of psoriasis. Methods: The first 10 result pages of YouTube were searched using the term psoriasis treatment with applied filters. One-hundred and eighty-two videos were reviewed and characterized by the source of content. Results: Of the identified videos, 7.1 percent had medical institutions or verified physicians as authors; 12.1 percent had a media-affiliated author; 1.6 percent were posted by a pharmaceutical company; 11.5 percent contained "miracle-type" product advertisements with included links to product purchase websites; and 69.2 percent were holistic in nature, describing "natural" supplements and diets necessary for adequate psoriasis treatment and cure. Conclusion: This review emphasizes the need for an increase in the online presence of medical institutions to augment the dissemination of correct health information.

YouTube ™ is an open-access, non-peer reviewed video-hosting site and is used as a source of publicly available healthcare information. This study aimed to assess the thematic content of the most viewed videos relating to surgery and Crohn's Disease and to explore the viewer interactions to these videos. A search of YouTube ™ was carried out using one search string. The 50 most viewed videos were identified and categorised by source, content themes and assessed for viewer interactions. Video comments were used to describe the usefulness of the video content to viewers. The majority of videos were uploaded by patients (n=21).The remainder were uploaded by individual health care professionals (n=9), hospital/speciality associations (n=18) and industry (n=2). The median number of likes for patient videos was significantly higher than hospital/speciality association videos (p=<0.001). Patient videos received more comments praising the video content(n=27), and more comments asking for further information (n=14). The median number of likes for 'experience of surgery' (p=<0.001) and 'experience ofdisease' (p=0.0015) themed videos, were significantly higher than 'disease management' themed videos. Crohn's disease patients use YouTube ™ as a surgical information source. The content of patient sourced videos focused on surgical and disease experience, suggesting these themes are important to patients.Current patient developed videos provide limited information, as reflected by viewers requesting further information. Storytelling patient-centred videos combined with clinical evidence may be a good model for future videos. This article is protected by copyright. All rights reserved.

Dental fear and anxiety (DFA) refers to the fear of and anxiety towards going to the dentist. It exists in a considerable proportion of children and adolescents and is a major dilemma in pediatric dental practice. As an Internet social medium with increasing popularity, the video-sharing website YouTube offers a useful data source for understanding health behaviors and perceptions of the public. Using YouTube as a platform, this qualitative study aimed to examine the manifestations, impacts, and origins of DFA in children and adolescents from the public's perspective. To retrieve relevant information, we searched YouTube using the keywords "dental fear", "dental anxiety", and "dental phobia". Videos in English expressing a layperson's views or experience on children's or adolescent's DFA were selected for this study. A video was excluded if it had poor audiovisual quality, was irrelevant, was pure advertisement or entertainment, or contained only the views of professionals. After the screen, we transcribed 27 videos involving 32 children and adolescents, which were reviewed by a panel of 3 investigators, including a layperson with no formal dental training. Inductive thematic analysis was applied for coding and interpreting the data. The videos revealed multiple manifestations and impacts of DFA, including immediate physical reactions (eg, crying, screaming, and shivering), psychological responses (eg, worry, upset, panic, helplessness, insecurity, resentment, and hatred), and uncooperativeness in dental treatment. Testimonials from children, adolescents, and their parents suggested diverse origins of DFA, namely personal experience (eg, irregular dental visits and influence of parents or peers), dentists and dental auxiliaries (eg, bad manner, lack of clinical skills, and improper work ethic), dental settings (eg, dental chair and sounds), and dental procedures (eg, injections, pain, discomfort, and aesthetic concerns). This qualitative study suggests that DFA in

We know little about how social media alcohol marketing is utilized for alcohol promotion in different national contexts. There does not appear to be any academic work on online exposure to alcohol marketing via social media in India, and most of the limited research in Australia has focused on Facebook. Hence, the present study extends previous research by investigating alcohol promotion conducted on an under-researched form of social media (YouTube) in two contrasting geographic contexts. This study examines and compares the types of strategies used by marketers on Indian and Australian alcohol brands with the greatest YouTube presence, and the extent to which users engage with these strategies. The 10 alcohol brands per country with the greatest YouTube presence were identified based on the number of 'subscriptions'. The number of videos, views per video, and the type of content within the videos were collected for each brand. The data were analyzed using an inductive coding approach, using NVivo 10. The targeted brands had gathered 98,881 subscriptions (Indian brands: n = 13,868; Australian brands: n = 85,013). The type of marketing strategies utilized by brands were a mix of those that differed by country (e.g. sexually suggestive content in India and posts related to the brand's tradition or heritage in Australia) and generic approaches (e.g. encouraging time- and event-specific drinking; demonstrations of food/cocktail recipes; camaraderie; competitions and prize draws; and brand sponsorship at music, sports, and fashion events). This cross-national comparison demonstrates that YouTube provides alcohol marketers with an advertising platform where they utilize tailored marketing approaches to cater to specific national contexts and develop content on the cultural meanings users invoke in their interactions with these strategies. Those exposed to alcohol marketing on YouTube are likely to include those under the legal drinking age.

NASA’s OSIRIS-REx asteroid sample return mission launched OSIRIS-REx Presents 321Science!, a series of short videos, in December 2013 at youtube.com/osirisrex. A multi-disciplinary team of communicators, film and graphic arts students, teens, scientists, and engineers produces one video per month on a science and engineering topic related to the OSIRIS-REx mission. The format is designed to engage all members of the public, but especially younger audiences with the science and engineering of the mission. The videos serve as a resource for team members and others, complementing more traditional formats such as formal video interviews, mission animations, and hands-on activities. In creating this new form of OSIRIS-REx engagement, we developed 321Science! as an umbrella program to encourage expansion of the concept and topics beyond the OSIRIS-REx mission through partnerships. Such an expansion strengthens and magnifies the reach of the OSIRIS-REx efforts.321Science! has a detailed proposed schedule of video production through launch in 2016. Production plans are categorized to coincide with the course of the mission beginning with Learning the basics - about asteroids and the mission - and proceeding to Building the spacecraft, Run up to launch, Cruising to Bennu, Run up to rendezvous, Mapping Bennu, Sampling, Analyzing data, Cruising home and Returning and analyzing the sample. The video library will host a combination of videos on broad science topics and short specialized concepts with an average length of 2-3 minutes. Video production also takes into account external events, such as other missions’ milestones, to draw attention to our videos. Production will remain flexible and responsive to audience interests and needs and to developments in the mission, science, and external events. As of August 2014, 321Science! videos have over 22,000 views. We use YouTube analytics to evaluate our success and we are investigating additional and more rigorous evaluation

Physics Girl: Where Education meets Cat Videos

Cowern, Dianna

YouTube is usually considered an entertainment medium to watch cats, gaming, and music videos. But educational channels have been gaining momentum on the platform, some garnering millions of subscribers and billions of views. The Physics Girl YouTube channel is an educational series with PBS Digital Studios created by Dianna Cowern. Using Physics Girl as an example, this talk will examine what it takes to start a short-form educational video series, including logistics and resources. One benefit of video is that every failure is documented on camera and can, and will, be used in this talk as a learning tool. We will look at the channels demographical reach, discuss best practices for effective physics outreach, and survey how online media and technology can facilitate good and bad learning. The aim of this talk is to show how videos are a unique way to share science and enrich the learning experience, in and out of a classroom.

This paper proposes a low-complexity multiple-window video embedding transcoder (MW-VET) based on H.264/AVC standard for various applications that require video embedding services including picture-in-picture (PIP), multichannel mosaic, screen-split, pay-per-view, channel browsing, commercials and logo insertion, and other visual information embedding services. The MW-VET embeds multiple foreground pictures at macroblock-aligned positions. It improves the transcoding speed with three block level adaptive techniques including slice group based transcoding (SGT), reduced frame memory transcoder (RFMT), and syntax level bypassing (SLB). The SGT utilizes prediction from the slice-aligned data partitions in the original bitstreams such that the transcoder simply merges the bitstreams by parsing. When the prediction comes from the newly covered area without slice-group data partitions, the pixels at the affected macroblocks are transcoded with the RFMT based on the concept of partial reencoding to minimize the number of refined blocks. The RFMT employs motion vector remapping (MVR) and intra mode switching (IMS) to handle intercoded blocks and intracoded blocks, respectively. The pixels outside the macroblocks that are affected by newly covered reference frame are transcoded by the SLB. Experimental results show that, as compared to the cascaded pixel domain transcoder (CPDT) with the highest complexity, our MW-VET can significantly reduce the processing complexity by 25 times and retain the rate-distortion performance close to the CPDT. At certain bit rates, the MW-VET can achieve up to 1.5 dB quality improvement in peak signal-to-noise-ratio (PSNR).

Although social media ubiquitously supplementstraditional information sources such as newspapers,magazines, radio, and television, investigation of onlinehealth information related to sun protection and skincancer prevention has been scarce and largely limitedto English language sources. Using the search terms"sun protection," "sunscreen," "skin cancer prevention,"tanning bed" and "vitamin D," we investigated 281YouTube videos presented in 6 languages: English,German, French, Spanish, Swedish, and Danish. Foreach video, we used a four-sectioned checklist toassess general information, popularity, expert drivenmeasures, and heuristic driven measures. Differencesbetween languages were detected: English languagevideos were most frequently viewed (median numberof views: 5488 compared to 248 -1591 in otherlanguages). Approximately 60% of videos revealednegative effects of solar ultraviolet (UV)-exposure.The majority of videos (75%) targeted adults. Videoson tanning beds and sunscreen contained false ormisleading information 40% and 20% of the time,respectively. We confirm observations made withrespect to other medical disciplines that the generalquality of YouTube contributions is often inferiorand does not deliver sustainable information. Othersources of information should be included whensearching for health information online.

The Internet has become the largest, most up-to-date source for medical information. Besides enhancing patients' knowledge, the freely accessible audio-visual files have an impact on medical education. However little is known about their characteristics. In this manuscript the quality of lumbar puncture (LP) and spinal anaesthesia (SA) videos available on YouTube is assessed. This retrospective analysis was based on a search for LP and SA on YouTube. Videos were evaluated using essential key points (5 in SA, 4 in LP) and 3 safety indicators. Furthermore, violation of sterile working techniques and a rating whether the video must be regarded as dangerously misleading was performed. From 2321 hits matching the keywords, 38 videos were eligible for evaluation. In LP videos, 14% contained information on all, 4.5% on 3 and 4.5% on 2 key points, 59% on 1 and 18% on no key point. Regarding SA, no video contained information on all 5 key points, 56% on 2-4 and 25% on 1 key point, 19% did not contain any essential information. A sterility violation occurred in 11%, and 13% were classified as dangerously misleading. Even though high quality videos are available, the quality of video clips is generally low. The fraction of videos that were not performed in an aseptic manner is low, but these pose a substantial risk to patients. Consequently, more high-quality, institutional medical learning videos must be made available in the light of the increased utilization on the Internet. Copyright © 2012 Elsevier B.V.

To analyse extent, nature and potential impact of marketing by food and beverage brands popular in New Zealand on Facebook and YouTube. Popular food and beverage brands in New Zealand were selected from Socialbakers. Posts on Facebook pages of 45 packaged food, beverage and fast food companies over two months and YouTube channels of 15 companies over two years were analysed for nutritional quality and use of activities, promotional strategies (eg, cartoons) and premium offers (eg, competitions). The 45 brands selected made 762 Facebook posts during October-November 2016. About 28% of posts were videos and 2/3 (63%) contained at least one occasional (ie, unhealthy) food. Promotional strategies were used in 41% of posts, with a famous sportsperson/team being the most frequently used. Premium offers were used in 34% of posts, with competitions being the most frequently used. It was estimated some posts could potentially reach 10% of New Zealand adolescents. The 15 food brands selected posted about 300 videos on their YouTube channels during 2015-2016. About 84% of videos contained food marketing and 77% of products marketed were occasional. Promotional strategies and premium offers were used in 61% and 24% of videos respectively, and the most common marketing techniques were the same as on Facebook. Social media is an important medium for food marketers in New Zealand and promotional strategies and premium offers are frequently used. Methodology needs to be developed to monitor actual exposure to such advertisements.

Dental Fear and Anxiety in Children and Adolescents: Qualitative Study Using YouTube

PubMed Central

Hamzah, SH; Yiu, Cynthia Kar Yung; McGrath, Colman; King, Nigel M

2013-01-01

Background Dental fear and anxiety (DFA) refers to the fear of and anxiety towards going to the dentist. It exists in a considerable proportion of children and adolescents and is a major dilemma in pediatric dental practice. As an Internet social medium with increasing popularity, the video-sharing website YouTube offers a useful data source for understanding health behaviors and perceptions of the public. Objective Using YouTube as a platform, this qualitative study aimed to examine the manifestations, impacts, and origins of DFA in children and adolescents from the public’s perspective. Methods To retrieve relevant information, we searched YouTube using the keywords “dental fear”, “dental anxiety”, and “dental phobia”. Videos in English expressing a layperson’s views or experience on children’s or adolescent’s DFA were selected for this study. A video was excluded if it had poor audiovisual quality, was irrelevant, was pure advertisement or entertainment, or contained only the views of professionals. After the screen, we transcribed 27 videos involving 32 children and adolescents, which were reviewed by a panel of 3 investigators, including a layperson with no formal dental training. Inductive thematic analysis was applied for coding and interpreting the data. Results The videos revealed multiple manifestations and impacts of DFA, including immediate physical reactions (eg, crying, screaming, and shivering), psychological responses (eg, worry, upset, panic, helplessness, insecurity, resentment, and hatred), and uncooperativeness in dental treatment. Testimonials from children, adolescents, and their parents suggested diverse origins of DFA, namely personal experience (eg, irregular dental visits and influence of parents or peers), dentists and dental auxiliaries (eg, bad manner, lack of clinical skills, and improper work ethic), dental settings (eg, dental chair and sounds), and dental procedures (eg, injections, pain, discomfort, and

Between butch/femme: On the performance of race, gender, and sexuality in a YouTube web series.

Drawing on a legacy of Black television and film production, Black web series remediate earlier media forms in order to usher in a twenty-first-century revival of indie Black cultural production. Specifically, video sharing and social media platforms operate as a sphere in which content creators and users are afforded unique opportunities to engage with video content and each other on a variety of levels. Focusing on the YouTube media sphere, one can also observe the myriad ways in which the performance of race, gender, and sexuality influences the types of discourse that circulate within these sites. In watching and analyzing Black queer web series on YouTube, I examine how the performance of gender and sexuality by Black queer women within and outside of web series are policed and protected by both community insiders and outsiders. Utilizing an ethnographic framework, which includes a critical discourse analysis of the YouTube comments for the series Between Women, as well as a textual analysis of series content, this project draws conclusions about the role that the politics of pleasure, performance, and the public sphere play in the recognition and/or refusal of queer sexuality within Black communities.

With a monthly total of more than one billion unique visitors, YouTube TM is one of the Internet's most visited websites and contributes to the growing amount of health-related information on the Internet. The purpose of this study was to analyze coverage of mammography screening in popular YouTube TM videos. A total of 173 videos were included in the analysis. Compared with professionally created videos, consumer-created videos had a significantly greater number of comments (>9 comments 38.0% for consumer vs. 11.8% for professional videos, p=<0.001). Videos created by professionals more often portrayed general mammography information (97.1 vs. 88.7%) compared to those created by consumers. The vast majority of videos presented general information (93.6%) related to mammography, and almost two thirds addressed preparing for the test. Less than 20% dealt with other types of examinations. Approximately 30% discussed pain associated with the examination (35.3%) and addressed issues of anxiety (32.4%) and fear (29.5%). Nearly half of the videos presented information about the test results (46.2%). Over 25% covered medical or family history. The majority did not pertain to a specific age group. Future research should focus on analyzing the accuracy of the information in the videos.

The cell phone expansion provides an additional direction for digital video content distribution: music clips, news, sport events are more and more transmitted toward mobile users. Consequently, from the watermarking point of view, a new challenge should be taken: very low bitrate contents (e.g. as low as 64 kbit/s) are now to be protected. Within this framework, the paper approaches for the first time the mathematical models for two random processes, namely the original video to be protected and a very harmful attack any watermarking method should face the StirMark attack. By applying an advanced statistical investigation (combining the Chi square, Ro, Fisher and Student tests) in the discrete wavelet domain, it is established that the popular Gaussian assumption can be very restrictively used when describing the former process and has nothing to do with the latter. As these results can a priori determine the performances of several watermarking methods, both of spread spectrum and informed embedding types, they should be considered in the design stage.

Cosmopolitan communication online: YouTube responses to the anti-Islam film Fitna.

Mihelj, Sabina; van Zoonen, Liesbet; Vis, Farida

2011-12-01

In 2008, a Dutch member of parliament released a short anti-Islamic film entitled Fitna, which stirred a huge public controversy and provoked public condemnations around the world. In response to the film, hundreds of videos were uploaded on YouTube, mostly with the aim to provide a more positive representation of Islam, express support for the author and his views, or defend his freedom of speech. Drawing on interviews with YouTube users who posted the videos, this paper reflects on the capacity of the Internet to sustain cosmopolitan communication and examines how cosmopolitan attitudes and practices on-line differ depending on the participants' cultural and social background, especially their religious affiliations. Particular attention is paid to how the opportunities for cosmopolitan communication are shaped by the unequal distribution of cosmopolitan attitudes and practices among groups, and by global inequalities of power. In addressing these issues, the paper also engages with broader debates about cosmopolitanism, and argues for an understanding of cosmopolitanism as a quest for universalism, which remains anchored in the particular, but involves communication across difference, and requires openness to the possibility that the other is right. © London School of Economics and Political Science 2011.

Know your data: understanding implicit usage versus explicit action in video content classification

NASA Astrophysics Data System (ADS)

Yew, Jude; Shamma, David A.

2011-02-01

In this paper, we present a method for video category classification using only social metadata from websites like YouTube. In place of content analysis, we utilize communicative and social contexts surrounding videos as a means to determine a categorical genre, e.g. Comedy, Music. We hypothesize that video clips belonging to different genre categories would have distinct signatures and patterns that are reflected in their collected metadata. In particular, we define and describe social metadata as usage or action to aid in classification. We trained a Naive Bayes classifier to predict categories from a sample of 1,740 YouTube videos representing the top five genre categories. Using just a small number of the available metadata features, we compare the classifications produced by our Naive Bayes classifier with those provided by the uploader of that particular video. Compared to random predictions with the YouTube data (21% accurate), our classifier attained a mediocre 33% accuracy in predicting video genres. However, we found that the accuracy of our classifier significantly improves by nominal factoring of the explicit data features. By factoring the ratings of the videos in the dataset, the classifier was able to accurately predict the genres of 75% of the videos. We argue that the patterns of social activity found in the metadata are not just meaningful in their own right, but are indicative of the meaning of the shared video content. The results presented by this project represents a first step in investigating the potential meaning and significance of social metadata and its relation to the media experience.

To investigate the content, quality and popularity of information about type 2 diabetes available on YouTube. We searched YouTube with the terms Diabetes, Diabetes type 2, Diabetes South Asians, Diabetes Punjabi and Diabetes Hindi to identify videos concerning type 2 diabetes. A team of health-care providers independently classified the first 20 videos from each search as useful, misleading, or personal experience, rated them on a 5-point global quality scale (GQS) and categorized their content on a 26-point scale in duplicate. Useful videos were rated for reliability by using a 5-point modified DISCERN scale. Higher scores represent better quality, reliability and comprehensiveness. Of 100 videos, 71 met the inclusion criteria; 45 (63.4%) were rated as useful (median GQS, 3; interquartile range [IQR], 2 to 4); and 23 (32.4%) were deemed misleading (median GQS, 1; IQR, 1 to 2). Median reliability and content scores for useful videos were 3 (IQR, 2 to 3) and 5 (IQR, 3 to 10), respectively, and 6 videos met ≥ 4 of 5 reliability criteria. Overall, misleading videos were more popular than useful videos (median, 233 views/day; IQR, 26 to 523; vs. 8.3 views/day; IQR, 0.4 to 134.6; p<0.01). Culturally tailored videos were just as likely to be misleading and had similar GQS scores in comparison to nonculturally tailored videos (32.1% vs. 32.6% and 3 vs. 3, respectively). The quality of identified videos concerning type 2 diabetes was variable, and misleading videos were popular. Further creation and curation of high-quality video resources is required.

2017-03-01

We investigated whether exposure to same humorous antitobacco videos via different types of social media platforms and contexts (health vs. humor) influences individual's health risk perceptions, attitudes, and behavioral intents. An experiment with a 2 (social media types: YouTube and Facebook) × 2 (message contexts: health-focused and humor-focused contexts) factorial design was conducted. It was found that those who watched the humorous antitobacco videos on Facebook in the health-context exhibited a higher level of risk perception of smoking, less positive attitude toward smokers, and a higher level of intention to avoid smoking in the future than the participants who viewed the same videos on YouTube in the health-context or on Facebook in the humor-context. These findings provide useful practical guidelines in using social media for health communication/promotion. Humorous health promotion messages are best circulated on social networking sites such as Facebook accompanied by others' support for the given health topic (i.e., in health-contexts). Practical/theoretical implications and limitations of the study were further discussed in this article.

To measure the usage rate of social media (SoMe) resources in the prostate cancer community, we performed a comprehensive quantitative and qualitative assessment of SoMe activity on the topic of PCa on the four most frequented platforms. We scanned the SoMe platforms Facebook, Twitter, YouTube, and Instagram for "prostate cancer" as a cross-sectional analysis or during a defined time period. Sources were included if their communication centered on PCa by title and content. We assessed activity measurements for each SoMe source and classified the sources into six functional categories. We identified 99 PCa-related Facebook groups that amassed 31,262 members and 90 Facebook pages with 283,996 "likes". On YouTube, we found 536 PCa videos accounting for 43,966,634 views, 52,655 likes, 8597 dislikes, and 12,393 comments. During a 1-year time period, 32,537 users generated 110,971 tweets on #ProstateCancer on Twitter, providing over 544 million impressions. During a 1-month time period, 638 contributors posted 1081 posts on Instagram, generating over 22,000 likes and 4,748,159 impressions. Among six functional categories, general information/support dominated the SoMe landscape on all SoMe platforms. SoMe activity on the topic of PCa on the four most frequented platforms is high. Facebook groups, YouTube videos, and Twitter tweets are mainly used for giving general information on PCa and education. High SoMe utilization in the PCa community underlines its future role for communication of PCa.

Physicians should be aware of both websites and videos available online regarding the otoplasty procedure to provide quality care. This study systematically analyzes the authorships, reliability, quality, and readability of the websites, as well as the authorships and primary objectives of the videos regarding otoplasty. Validated instruments were used to analyze the reliability, quality, and readability of websites, and videos were systematically categorized and analyzed. A Google search was conducted, and the first five pages of results were included in this study. After excluding unrelated websites, the remaining 44 websites were categorized by authorship (physician, patient, academic, or unaffiliated) and were analyzed using the validated DISCERN instrument for reliability and quality, as well as various other validated instruments to measure readability. A YouTube search was also conducted, and the first 50 relevant videos were included in the study. These videos were categorized by authorship and their primary objective. Website authorships were physician-dominated. Reliability, quality, and overall DISCERN score differ between the four authorship groups by a statistically significant margin (Kruskall-Wallis test, p  < 0.05). Unaffiliated websites were the most reliable, and physician websites were the least reliable. Academic websites were of the highest quality, and patient websites were of the lowest quality. Readability did not differ significantly between the groups, though the readability measurements made showed a general lack of material easily readable by the general public. YouTube was likewise dominated by physician-authored videos. While the physician-authored videos sought mainly to inform and to advertise, patient-authored videos sought mainly to provide the patient's perspective. Academic organizations showed very little representation on YouTube, and the YouTube views on otoplasty videos were dominated by the top 20 videos, which

Students are exposed to a variety of unrealistic physical experiences seen in movies, video games, and short online videos. A popular classroom activity has students examine footage to identify what aspects of physics are correctly and incorrectly represented.1-7 Some of the physical phenomena pictured might be tricks or illusions made easier to perform with the use of video, while others are removed from their historical context, leaving the audience to form misguided conclusions about what they saw with only the information in the video. One such video in which the late Eric Laithwaite, a successful British engineer and inventor, claims that a spinning wheel "becomes light as a feather" provides an opportunity for students to investigate Laithwaite's claim.8 The use of video footage can engage students in learning physics9 but also provide an opportunity for authentic research experiences.

Tiny videos: a large data set for nonparametric video retrieval and frame classification.

PubMed

Karpenko, Alexandre; Aarabi, Parham

2011-03-01

In this paper, we present a large database of over 50,000 user-labeled videos collected from YouTube. We develop a compact representation called "tiny videos" that achieves high video compression rates while retaining the overall visual appearance of the video as it varies over time. We show that frame sampling using affinity propagation-an exemplar-based clustering algorithm-achieves the best trade-off between compression and video recall. We use this large collection of user-labeled videos in conjunction with simple data mining techniques to perform related video retrieval, as well as classification of images and video frames. The classification results achieved by tiny videos are compared with the tiny images framework [24] for a variety of recognition tasks. The tiny images data set consists of 80 million images collected from the Internet. These are the largest labeled research data sets of videos and images available to date. We show that tiny videos are better suited for classifying scenery and sports activities, while tiny images perform better at recognizing objects. Furthermore, we demonstrate that combining the tiny images and tiny videos data sets improves classification precision in a wider range of categories.
