Purpose: This study aims to evaluate video quality, reliability, actionability, and understandability differences based on length, popularity, and source credentials (physician versus non-physician). The hypothesis suggests that current videos are of low quality and limited usefulness to patients, highlighting significant disparities based on the credentials of the video source.
Methods: The phrase "acromioclavicular joint separation" was searched on YouTube. The first 100 videos that populated were selected. Of those 100, 45 were excluded based on pre-existing criteria. Two reviewers watched and graded the included videos using four established, additive algorithmic grading scales. Grades for all included videos were analyzed using R software version 4.2.3.
Results: The mean Journal of the American Medical Association (JAMA) score was 2.32 (standard deviation (SD) = 0.74), with patient-made videos having a significantly lower reliability score (p = 0.008). The mean Patient Education Materials Assessment Tool (PEMAT) understandability and actionability scores were 59.78% (SD = 15.28%) and 67.55% (SD = 15.28%) respectively. PEMAT actionability scores were positively correlated to views (p = 0.002). The average DISCERN score was 2.51 (SD = 0.70); longer videos were correlated with higher DISCERN scores (p = 0.047).
Conclusion: Analysis indicated that there were significant differences in reliability and understandability between video source types. Additionally, there was no correlation between quality and/or reliability and views, indicating that the YouTube algorithm is not an effective indicator of the quality of videos.

Background: Social media is a significant source of information on health-related topics and neurodevelopmental disorders such as autism spectrum disorder (ASD). The public perception of ASD, as reflected on social media, can raise awareness but also increase stigma. This study examined ASD portrayal on TikTok, focusing on neurodiversity, content themes, creator identities, and the depiction of autistic individuals.

Compact Monocular Video-Ophthalmoscope to Measure Retinal Reflectance Changes to Flicker Light Stimuli.

This paper describes a compact video-ophthalmoscope (VO) designed for capturing retinal video sequences of the optic nerve head (ONH) under flicker light stimulation. The device uses an OLED display and a fiber optic-coupled LED light source, enabling high-frame-rate video at low illumination intensity (12 μW/cm). Retinal responses were recorded in 10 healthy subjects during flicker light exposure with a pupil irradiance of 2 μW/cm.

The CrumpCAT is a prototype small-animal X-ray computed tomography (CT) scanner developed at our research institution. The CMOS detector with a maximum frame rate of 29 Hz and similar Tungsten X-ray sources with energies ranging from 50 kVp to 80 kVp are widely used across commercially available preclinical X-ray CT instruments. This makes the described work highly relevant to other institutions, despite the generally perceived wisdom that these detectors are not suitable for gating the high heart rates of mice (~600 beats/min).

Sequential sugar consumption, from a preferred sugar source to a less preferred one, represents a critical metabolic adaptation in yeast, which is particularly relevant for survival in fluctuating environments such as those found in beer fermentation. However, sugar transitions are an environmental variable that is challenging to predict and detect, impacting the outcome of beer fermentations. This protocol describes an in vivo system to monitor transcriptional activation associated with the glucose-to-maltose metabolic shift in Saccharomyces eubayanus that applies to different wild Saccharomyces yeast strains.
