AI Article Synopsis

  • The study evaluates the quality and reliability of brain tumor-related short videos on TikTok and Bilibili, revealing that TikTok videos generally score higher on key quality indicators.
  • Professional uploaders produce videos with better quality and reliability compared to non-professionals, particularly those focusing on disease knowledge.
  • Despite finding low overall quality and reliability, the number of followers is identified as a critical factor influencing how widely these videos are shared.

Article Abstract

Background: As the Internet becomes an increasingly vital source of medical information, the quality and reliability of brain tumor-related short videos on platforms such as TikTok and Bilibili have not been adequately evaluated. Therefore, this study aims to assess these aspects and explore the factors influencing the dissemination of such videos.

Methods: A cross-sectional analysis was conducted on the top 100 brain tumor-related short videos from TikTok and Bilibili. The videos were evaluated using the Global Quality Score and the DISCERN reliability instrument. An eXtreme Gradient Boosting algorithm was utilized to predict dissemination outcomes. The videos were also categorized by content type and uploader.

Results: TikTok videos scored relatively higher on both the Global Quality Score (median 2, interquartile range [2, 3] on TikTok vs. median 2, interquartile range [1, 2] on Bilibili,  = 1.51E-04) and the DISCERN reliability instrument (median 15, interquartile range [13, 18.25] on TikTok vs. 13.5, interquartile range [11, 16] on Bilibili,  = 1.66E-04). Subgroup analysis revealed that videos uploaded by professional individuals and institutions had higher quality and reliability compared to those uploaded by non-professional entities. Videos focusing on disease knowledge exhibited the highest quality and reliability compared to other content types. The number of followers emerged as the most important variable in our dissemination prediction model.

Conclusion: The overall quality and reliability of brain tumor-related short videos on TikTok and Bilibili were unsatisfactory and did not significantly influence video dissemination. Future research should expand the scope to better understand the factors driving the dissemination of medical-themed videos.

For over a century African swine fever (ASF) has been causing outbreaks leading to devastating losses for the swine industry. The current pandemic of ASF has shown no signs of stopping and continues to spread causing outbreaks in additional countries. Currently control relies mostly on culling infected farms, and strict biosecurity procedures.

Antimicrobial susceptibility testing (AST) in the veterinary sector by broth microdilution is mainly based on commercially available microtitre plates with specific panels. A critical review of commercially available microtitre panels identified AST panels that fulfil the requirements for obtaining reliable AST results by covering the necessary antimicrobial concentrations for both clinical breakpoints as well as quality control (QC) ranges for approved QC strains. However, there are AST panels in which these prerequisites are only in part fulfilled, and some AST panels that do not fulfil the aforementioned criteria at all.

This study introduces a novel method for achieving highly ordered-crystalline InGaO [0 ≤ x ≤ 0.6] thin films on Si substrates at 250 °C using plasma-enhanced atomic-layer-deposition (PEALD) with dual seed crystal layers (SCLs) of γ-AlO and ZnO. Field-effect transistors (FETs) with random polycrystalline InGaO channels (grown without SCLs) show a mobility (µFE) of 85.

Introduction/aims: A previous randomized controlled trial showed that guided self-help acceptance and commitment therapy plus standard medical care (ACT+SMC) was superior to standard medical care alone (SMC) for improving quality of life (QoL) and mood at 9-weeks post randomization in a sample of people with muscle disorders (MD). This follow-up study evaluated whether these effects were maintained in the longer term alongside individual patterns of response.

Methods: The original study was a two-arm parallel group randomized controlled trial, which compared ACT+SMC to SMC.

Objectives: The aim of this study was to adapt and apply the Portuguese version of the Transgender Man Voice Questionnaire in a sample of Brazilian transgender men and to investigate the relationship between voice satisfaction and hormone therapy duration. In addition, we suggest reducing and reformulating the questionnaire for screening.

Methods: We conducted a cross-sectional study of 31 transgender men aged 18-50 years undergoing hormone therapy who answered a questionnaire adapted from the Transgender Woman Voice Questionnaire, validated in Portuguese.
