Summary

This summary is machine-generated.

Short videos about the gut-liver axis often lack quality, despite high engagement. Content from healthcare professionals is more educational but less prioritized by algorithms. Promoting expert content is key for better digital health communication.

Area Of Science

  • Hepatology
  • Metabolic Diseases
  • Digital Health Communication

Background

  • The gut-liver axis is crucial in hepatology and metabolic disease research.
  • Public-facing health information quality, especially in short videos, is understudied.

Purpose Of The Study

  • To assess the quality and engagement of short-form videos discussing the gut-liver axis.
  • To compare video quality across different platforms and content creators.

Main Methods

  • Systematic screening and analysis of 210 short videos on the gut-liver axis (Jan 2021-Oct 2025).
  • Assessment of video quality using modified DISCERN, JAMA Benchmark Criteria, and Global Quality Score (GQS).
  • Exploration of correlations between video metrics and quality scores using Pearson correlation.

Main Results

  • Bilibili videos had the highest educational quality (mean GQS: 3.79), while TikTok videos showed greater engagement (median likes: 74.00).
  • Videos from healthcare professionals significantly outperformed others in quality measures (SUM score: 9.03 vs 3.87, p < 0.001).
  • No significant correlation was found between engagement metrics and content quality.

Conclusions

  • A gap exists between user engagement and informational quality in gut-liver short videos.
  • Expert-led content offers superior educational value but is algorithmically under-prioritized.
  • Enhancing digital health communication requires promoting expert content, verifying sources, and using quality-weighted algorithms.

Social Foundations of Self IV: Self in Digital Communication 01:30

154

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Assessment of the Mouth 01:26

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
