    The diagnostic value of hepatic arterial velocity in venoocclusive disease after pediatric hematopoietic stem cell transplantation
    (Lippincott Williams & Wilkins, 2017) Kaya, Nusabe; Erbey, Fatih; Atay, Didem; Akçay, Arzu; Bozkurt, Ceyhun; ÖztÜrk, GÜlyÜz
    The aim of this study was to determine usefulness of measurements of maximal systolic velocity of the hepatic artery with Doppler ultrasonography in the diagnosis of venoocclusive disease (VOD) after hematopoietic stem cell transplantation. We prospectively obtained 5 sonograms per patient: pretransplantation, day + 1, + 7, + 14, and + 28 on 36 nonconsecutive children who underwent hematopoietic stem cell transplantation. We examined the hepatic artery, the portal, hepatic and splenic veins, the thickness of the gallbladder wall, the presence of ascites, and the liver and spleen size. The diagnosis of VOD was based on clinical and laboratory data. Patients were divided into 2 groups: those with VOD (n=18) and those without VOD (n=18). The variance of 2 groups was analyzed. V-max of the hepatic artery had a strong correlation with clinical VOD diagnosis (P<0.001). There was no statistically significant difference in the other Doppler parameters. The results of our study showed that the measurement of V-max of the hepatic artery can provide important support in the diagnosis of VOD and can be useful in the follow-up of treatment response.

    The quality and content analysis of YouTube videos about chemotherapy for children
    (2024) Semerci, Remziye; Simsek, Enes; Savas, Eysan; Orhan, Eda; Erbey, Fatih
    Purpose: This study undertook a systematic examination of YouTube videos about chemotherapy for pediatric patients, with a primary focus on assessing the videos' quality, content, and reliability.Method: The research was conducted by searching YouTube using the keywords "chemotherapy for children" and "chemotherapy for pediatric," employing filters for "worldwide" and "all categories." The top 100 videos, based on popularity, were selected for evaluation according to the power analysis calculation. Two independent experts in pediatric oncology reviewed these videos. Video characteristics were recorded: length, view count, likes, dislikes, view ratio, and video-like ratio. The Video Power Index was calculated to measure video popularity. The modified DISCERN and Global Quality Scale (GQS) assessed the videos for quality and reliability.Results: The 100 videos were analyzed. Official health institutions uploaded 54%, while independent users contributed 46%. Independent user uploads garnered significantly more views than official health institutions (p = .006). The number of likes, view ratio, and Video Power Index of independent users' videos were significantly higher than official health institutions' videos (respectively, p = .007, .007, and .008). On the other hand, the modified DISCERN score and GQS were significantly higher in YouTube videos of official health institutions than in independent users (p < .001). A strong correlation was observed between the modified DISCERN score and GQS (r = .879, p < .001).Conclusion: This study provides valuable insights into the YouTube videos on pediatric chemotherapy, emphasizing the need to improve the quality and reliability of online health information for this vulnerable population.
