Background YouTube (TM) is a platform that many people, including patients, use to access health information. Recent studies have revealed that videos on YouTube (TM) are misleading or that medical videos may not contain appropriate information. This study aimed to assess the quality and reliability of videos on nutrition after bariatric surgery. Materials and Methods The keywords "after bariatric surgery diet" and "weight loss surgery postop diet" were used, and the first 100 videos for each keyword on YouTube (TM) were analyzed by considering the source, duration, content, and the number of likes of the video. The popularity of the video was calculated using the video power index (VPI) and view rate. The educational quality of the videos was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) score, the Global Quality Score (GQS), the usefulness score, and a novel postoperation nutrition score (PONS). Results One hundred fourteen patients were included in the study. The mean duration and number of views were 12.51 min and 87,558.46, respectively. The DISCERN score, JAMA score, GQS, and usefulness score of the physicians or dietician-based videos were significantly higher than those of the patient-based videos (p < 0.001). Positive correlations were found between the VPI and view ratio, as well as between the duration and number of likes. Additionally, the DISCERN score was significant correlated with the duration and number of likes. Significantly positive correlations were found between the usefulness score and duration, usefulness score and number of likes, and PONS and duration (p < 0.01). Conclusions Informational videos on nutrition after bariatric surgery on YouTube (TM) are of low quality. Although the videos uploaded by physicians and dieticians have higher quality, only a few are available. Additionally, patients prefer to watch low-quality videos.

Relationship Between Weight Loss and Dietary Inflammatory Index and Serum C-Reactive Protein Level Before and After Bariatric Surgery
(Mary Ann Liebert, inc, 2023) Sevdin, Sezen; Ozturk, Elif Sila; Sevdin, Sezen; Yildiz, Nida; Beslenme ve Diyetetik Bölümü
Background: This study aims to evaluate the relationship between weight loss, dietary inflammatory index (DII), and serum C-reactive protein (CRP) levels in patients who underwent sleeve gastrectomy (SG).Materials and Methods: This research is a retrospective cross-sectional study. We enrolled patients who had obesity surgery in a private clinic in Istanbul, Turkey, between February 1, 2014, and February 1, 2018. Pre-operative (pre-op) and 12th, 18th, and 24th month post-operative (post-op) weight, nutritional consumption, and CRP levels of the participants were evaluated. The DII scores of the individuals were calculated from the obtained dietary data.Results: In this study, a total of 140 SG patients, 100 women and 40 men, were evaluated. It was found that there was a positive and significant correlation between the decreasing body mass index (BMI) value and CRP value of the individuals. It was concluded that for all measurements of BMI, excessive weight loss, DII, and CRP, at least one measurement significantly differentiated from the other measurements. Post-op 18th month DII was significantly higher than the post-op 24th month DII value.Conclusions: Long-term follow-up of patients by a multidisciplinary team in the pre-op and post-op periods is required to ensure success in bariatric surgery results. Dieticians play an important role in changing and sustaining eating habits.
