Background: ChatGPT and language learning models have gained attention recently for their ability to answer questions on various examinations across various disciplines. The question of whether ChatGPT could be used to aid in medical education is yet to be answered, particularly in the field of ophthalmology. Objective: The aim of this study is to assess the ability of ChatGPT-3.5 (GPT-3.5) and ChatGPT-4.0 (GPT-4.0) to answer ophthalmology-related questions across different levels of ophthalmology training. Methods: Questions from the United States Medical Licensing Examination (USMLE) steps 1 (n=44), 2 (n=60), and 3 (n=28) were extracted from AMBOSS, and 248 questions (64 easy, 122 medium, and 62 difficult questions) were extracted from the book, Ophthalmology Board Review Q&A, for the Ophthalmic Knowledge Assessment Program and the Board of Ophthalmology (OB) Written Qualifying Examination (WQE). Questions were prompted identically and inputted to GPT-3.5 and GPT-4.0. Results: GPT-3.5 achieved a total of 55% (n=210) of correct answers, while GPT-4.0 achieved a total of 70% (n=270) of correct answers. GPT-3.5 answered 75% (n=33) of questions correctly in USMLE step 1, 73.33% (n=44) in USMLE step 2, 60.71% (n=17) in USMLE step 3, and 46.77% (n=116) in the OB-WQE. GPT-4.0 answered 70.45% (n=31) of questions correctly in USMLE step 1, 90.32% (n=56) in USMLE step 2, 96.43% (n=27) in USMLE step 3, and 62.90% (n=156) in the OB-WQE. GPT-3.5 performed poorer as examination levels advanced (P<.001), while GPT-4.0 performed better on USMLE steps 2 and 3 and worse on USMLE step 1 and the OB-WQE (P<.001). The coefficient of correlation (r) between ChatGPT answering correctly and human users answering correctly was 0.21 (P=.01) for GPT-3.5 as compared to –0.31 (P<.001) for GPT-4.0. GPT-3.5 performed similarly across difficulty levels, while GPT-4.0 performed more poorly with an increase in the difficulty level. Both GPT models performed significantly better on certain topics than on others. Conclusions: ChatGPT is far from being considered a part of mainstream medical education. Future models with higher accuracy are needed for the platform to be effective in medical education.

Introduction. Social media has increasingly become a prominent source of health information. Platforms like TikTok that allow for videos to reach millions of viewers have become among the most common platforms to share and receive health information. Laser in situ keratomileusis (LASIK) videos and patients’ experiences are commonly discussed on social media. The quality of these videos remains to be assessed. The aim of this study is to evaluate the content, quality, and reach of the top 100 videos related to LASIK eye surgery on TikTok. Methods. Video quality was assessed using the DISCERN, JAMA, and GQS instruments which have all been proven to be both reliable and valid. Results. 100 videos were included in the study. Results showed that the videos have an immense reach with a total view count of 245 million views and 21.9 million likes. Two thirds of the videos were posted by personal accounts as compared ophthalmologists that only constituted 26% of the content. Healthcare professionals produced higher quality videos compared to nonhealthcare professionals (p<0.0001) although there was no significant difference in video duration (p=0.18). Increased duration, view count, comments, shares, saves, and views/day were all associated with increased DISCERN score and quality of the videos. Educational videos were of higher quality compared to entertainment videos, and videos outlining the procedure details had the highest quality score. Conclusions. LASIK videos on TikTok have established a wide reach, whereby viewers are highly interacting and viewing these videos. It appeared that viewers interacted more with the higher quality videos. Ophthalmologists approximately only contributed to a quarter of the videos analyzed in this study. This highlights the need for ophthalmologists to establish a presence on TikTok and produce high quality videos.

Background: Social media platforms like TikTok are a very popular source of information, especially for skin diseases. Topical steroid withdrawal (TSW) is a condition that is yet to be fully defined and understood. This did not stop the hashtag #topicalsteroidwithdrawal from amassing more than 600 million views on TikTok. It is of utmost importance to assess the quality and content of TikTok videos on TSW to prevent the spread of misinformation. Objective: This study aims to assess the quality and content of the top 100 videos dedicated to the topic of TSW on TikTok. Methods: This observational study assesses the content and quality of the top 100 videos about TSW on TikTok. A total of 3 independent scoring systems: DISCERN, Journal of the American Medical Association, and Global Quality Scale were used to assess the video quality. The content of the videos was coded by 2 reviewers and analyzed for recurrent themes and topics. Results: This study found that only 10.0% (n=10) of the videos clearly defined what TSW is. Videos were predominantly posted by White, middle-aged, and female creators. Neither cause nor mechanism of the disease were described in the videos. The symptoms suggested itching, peeling, and dryness which resembled the symptoms of atopic dermatitis. The videos fail to mention important information regarding the use of steroids such as the reason it was initially prescribed, the name of the drug, concentration, mechanism of usage, and method of discontinuation. Management techniques varied from hydration methods approved for treatment of atopic dermatitis to treatment options without scientific evidence. Overall, the videos had immense reach with over 200 million views, 45 million likes, 90,000 comments, and 100,000 shares. Video quality was poor with an average DISCERN score of 1.63 (SD 0.56)/5. Video length, total view count, and views/day were all associated with increased quality, indicating that patients were interacting more with higher quality videos. However, videos were created exclusively by personal accounts, highlighting the absence of dermatologists on the platform to discuss this topic. Conclusions: The videos posted on TikTok are of low quality and lack pertinent information. The content is varied and not consistent. Health care professionals, including dermatologists and residents in the field, need to be more active on the topic, to spread proper information and prevent an increase in steroid phobia. Health care professionals are encouraged to ride the wave and produce high-quality videos discussing what is known about TSW to avoid the spread of misinformation.

Background: Low- and middle-income countries (LMICs) have been consistently under-represented in the pool of contributors to academic journals on health. For the past two decades, prominent voices within the psychiatric profession have called for better representation of LMICs in the interest of advancing the understanding of mental health globally and benefiting health systems in these countries. Objective: To investigate the absolute and relative representation of authors affiliated to institutes from LMICs in the most influential journals on mental health in 2019. Method: Thirty top-ranking journals on mental health based on Scimago Journal Rank were selected, and all papers other than correspondence and letters to the editor published in those journals in 2019 were examined to extract the country of affiliation of each of their authors and their position (corresponding author, first author, second author). Results: Of the 4022 articles examined, 3720 articles (92.5%) were written exclusively by authors from high-income countries (HICs); 302 (7.5%) featured one or more authors from a LMIC along with those from HICs; 91 (2.2%) featured authors only from one LMIC; and only 3 (0.07%) featured authors from more than one LMICs but without any co-author from a HIC. The ratio of articles by contributors from LMICs to all the articles published in 2019 in a given journal ranged from 0% to 19%. Of 1855 individual contributors from 45 LMICs, 1050 (56%) were from China. Conclusion: Despite the growth of the global health movement and frequent calls for academic inclusivity, LMICs were significantly under-represented among the authors of papers published in top-ranking journals on mental health in 2019.

Introduction: Diet is thought to play an important role in the clinical course and quality of life (QOL) of patients with inflammatory bowel disease (IBD). However, dietary habits of patients with IBD are still unknown. This case–control study aims to compare the dietary habits of patients with IBD to healthy controls and evaluate differences in disease severity and QOL. Materials and methods: Food frequency, severity scores using the Harvey–Bradshaw and Ulcerative colitis activity index, and QOL were assessed using online questionnaires. Dietary habits were compared for patients with active disease and remission and for those with low QOL (LQOL) and high QOL (HQOL). Results: We recruited 61 patients with IBD and 101 controls. Significance was set at p = 0.05. Controls consumed significantly more daily calories (2546 vs. 1641, p = 0.001). However, patients with IBD consumed a higher percentage of carbohydrates (50% vs. 45%, p = 0.001), more red meat (p = 0.024), and less fiber, sucrose, and lactose (p = 0.001, 0.001, and 0.036). Patients with active disease had higher lipid intake, lower protein intake, and lower QOL (47 vs. 58, p = 0.001). Dietary differences between LQOL and HQOL mirrored those between active disease and remission. Conclusion: This study is the first to provide valuable insights into the nutritional profile of Lebanese patients with IBD.

Background: Despite extensive research on sun protection, there remains a gap in certain populations like Lebanon. It is essential to assess how Lebanese adults handle sun exposure and its risks.Objectives: To examine the knowledge and habits of sun protection use among adults in Lebanon and explore the possible association between a history of skin cancer or photo‐related disorder and sun protection behaviours.Methods: We conducted a single‐centre cross‐sectional study on 1001 patients presenting to the American University of Beirut Medical Center dermatology clinics from August 2020 till April 2023. Participants were between 18 and 80 years of age and recruited by convenience sampling. Those younger than 18 years old or not proficient in English or Arabic were excluded.Results: Among 1001 adults (mean age, 36.06 years [SD, 14.72]; 708 [71.08%] female), 512 (52.78%) use sunscreen, 449 (46.29%) do not and 9 (0.93%) do not know. Respondents with a history of a photo‐related condition (melasma, lentigos/freckles and rosacea) were significantly more likely to be sunscreen users (p < 0.001), but a history of skin cancer did not significantly increase the odds of using sunscreen (odds ratio, 1.42; 95% confidence interval, 0.79–2.56). Participants who reported obtaining their sun protection information from dermatologists and/or social media were associated with increased sunscreen use.Conclusions: The results of this cross‐sectional survey suggest that half of the patients presenting to dermatology clinics at a tertiary care centre in Beirut tend to use sunscreen. Future investigations are needed to better understand the photoprotective awareness and practices of the Lebanese population. The lack of patients' behaviours towards skin protection should gear a nation‐wide campaign to improve these practices. Our outcomes indicate that dermatologists should be at the forefront of such campaigns tackling sun‐protective measures and skin cancer prevention, especially using social media platforms.
