Companies provide employees with occupational health and safety (OHS) training through videos on YouTube. In this study, the reliability of 118 YouTube videos related to OHS was evaluated by two experts using (JAMA) and global quality score (GQS) scales. Six video variables - video duration, number of subscribers, likes, views, publication time and comments - were evaluated based on video source (five groups) and type (seven groups). The correlation analysis found a positive significant relationship between all variables except publication time-number of comments. Scores according to video source and type were 1.9 out of 4 on the JAMA scale and 2.3 out of 5 on the GQS scale. These scores show that the videos are inadequate and of poor quality. There was a statistically significant difference between video durations according to video type. Moreover, video sources differ depending on the number of subscribers and comments.

Background: The prevalence of depressive symptoms, apathy, and cognitive decline increases with age. Understanding the temporal dynamics of these symptoms could provide valuable insights into the early stages of cognitive decline, allowing for more timely and effective treatment and management.
Methods: Participants from the Prevention of Dementia by Intensive Vascular Care (preDIVA) trial cohort with baseline and ≥3 follow-up measurements were included, with a median of 7.
Improving breaking bad news communication skills through stress arousal reappraisal and worked examples.

Institute for Medical Education, University of Bern, Bern, Switzerland.
Introduction: Breaking bad news (BBN) is a distressing yet essential task in medicine, imposing emotional strain on both physicians and patients. Crucially, effective BBN relies on both verbal and nonverbal communication, which can be impaired by elevated stress associated with the task. Efficient teaching of communication skills continues to present a challenge, and the role of stress management in BBN encounters remains largely overlooked.

Northwell Health Division of Medical Toxicology, North Shore University Hospital, Manhasset, NY.
Inhalation of elemental mercury is a rare cause of ARDS, with limited published case reports to provide guidance regarding disease progression and management. Although extracorporeal membrane oxygenation (ECMO) has been used to treat toxin-induced lung injury, its application to initial treatment and long-term recovery for inhalation of mercury remains undescribed. We present a case of a 56-year-old man who works at a thermometer factory presenting with severe ARDS secondary to inhaled elemental mercury with confirmatory blood and urine mercury levels.

Using a historical or "development from" approach to study the development of hand-use preferences in infants and children, we show how various sensorimotor experiential events shape the cascade from initial to subsequent hand-use preferences. That cascade represents, creates, and shapes the lateralized asymmetry of neural circuits in the cerebral hemispheres. The control of the preferred hand requires neural circuits in the contralateral hemisphere that are capable of processing the organization of finely timed, sequentially organized movements and detecting haptic information derived from high-frequency transitions in the stimulus.
