Tracheostomy-related emergencies (TREs) contribute significantly to preventable mortality. The retention of caregiver knowledge and skills acquired through simulation-based training (SBT) is unknown. This study aimed to assess the management of TREs by caregivers who did and did not receive SBT.
View Article and Find Full Text PDFPlants display a range of temporal patterns of inter-annual reproduction, from relatively constant seed production to "mast seeding," the synchronized and highly variable interannual seed production of plants within a population. Previous efforts have compiled global records of seed production in long-lived plants to gain insight into seed production, forest and animal population dynamics, and the effects of global change on masting. Existing datasets focus on seed production dynamics at the population scale but are limited in their ability to examine community-level mast seeding dynamics across different plant species at the continental scale.

- * This study creates a computer model to explore how reduced inactivation of calcium channels leads to fluctuating EADs, which can sync up in heart tissue due to the connections between cells, resulting in predictable patterns.
- * The results show that EADs occur after a sudden synchronization (alternans) of heart cells, driven by small changes in pacing rate, which significantly increases the risk of arrhythmias and suggests that abnormal heartbeats can occur without other triggering factors.
Article Synopsis
- A study was conducted on children with new tic disorders (less than 9 months) to explore the relationship between subcortical brain structure and tic symptoms over time.
- The research involved 187 children, grouping them into those with new tic disorders (NT), tic-free healthy controls (HC), and those with chronic tic disorders/Tourette syndrome (TS), assessing brain scans and tic severity scores.
- Findings revealed distinct structural differences, such as a larger right hippocampus in NT children and specific patterns of brain deformation, which could serve as early indicators of tic disorder outcomes regarding symptom improvement.
