Allostatic self-efficacy (ASE) represents a computational theory of fatigue and depression. In brief, it postulates that (i) fatigue is a feeling state triggered by a metacognitive diagnosis of loss of control over bodily states (persistently elevated interoceptive surprise); and that (ii) generalization of low self-efficacy beliefs beyond bodily control induces depression. Here, we converted ASE theory into a structural causal model (SCM).

The study objectives were to estimate longitudinal differences between birth seasons and production systems for lamb postweaning growth and indicators of GIN infection. Data were collected on Katahdin lambs within a single flock from 2006 to 2022.

- Sudden unexpected infant death (SUID), primarily from sudden infant death syndrome (SIDS), is a major cause of infant mortality, but there has been no focused study on SIDS content on YouTube despite its prevalence on platforms like Instagram and Twitter.
- This observational study, conducted between December 2023 and January 2024, analyzed the top 100 SIDS-related videos on YouTube, identifying that most were produced by organizations, with a strong emphasis on risk factors and prevention measures.
- The findings suggest the need for enhanced clinical and public health strategies to better utilize digital content to address SIDS risk factors and promote awareness, especially outside the United States, to ultimately reduce infant mortality rates worldwide.
The thromboelastogram is confounded by hematocrit in clinical samples tested on both mechanical and acoustic platforms.

Article Synopsis
- Red blood cells play a crucial role in hemostasis, but recent experiments reveal an unexpected inverse correlation between hematocrit levels and the maximum amplitude measured by thromboelastogram (TEG).
- A comprehensive review at a single institution analyzed 7,176 TEG samples taken shortly after hematocrit measurements, using both mechanical and acoustic TEG systems.
- Findings show that higher hematocrit is linked to lower maximum amplitude readings, indicating that TEG may not accurately reflect the role of red blood cells in normal blood clotting.
