Transitions in intensive care: Investigating critical slowing down post extubation.
PLoS One
January 2025
Department of Computer Science, University College London, London, United Kingdom.
Complex biological systems undergo sudden transitions in their state, which are often preceded by a critical slowing down of dynamics. This results in longer recovery times as systems approach transitions, quantified as an increase in measures such as the autocorrelation and variance. In this study, we analysed paediatric patients in intensive care for whom mechanical ventilation was discontinued through removal of the endotracheal tube (extubation).

VDAC1 Cleavage Promotes Autophagy in Renal Tubular Epithelial Cells With Hypoxia/Reoxygenation Injury.
Nephrology (Carlton)
February 2025
Department of Quality Management, Tianjin Blood Center, Tianjin, China.
Aim: To study the effect and elucidate the underlying mechanisms of VDAC1-ΔC on autophagy in renal tubular epithelial cells injured by hypoxia/reoxygenation.
Methods: C57/BL6 mice were randomly divided into groups: sham operation group, IRI 1d group and IRI 2d group. The inner canthal blood of mice was collected to detect the levels of serum creatinine and urea nitrogen and kidney tissues were sampled, and sections were stained with Periodic acid-Schiff for morphological evaluation.
Effects of osteosynthesis of the bony thorax in the context of polytrauma compared to conservative treatment: a systematic review.

Department of Intensive Care Medicine and Intermediate Care Medical Faculty, RWTH Aachen University, Pauwelsstr. 30, D-52074, Aachen, Germany.
Purpose: Osteosynthesis seems to have effects regarding clinical outcomes in trauma patients. However, current knowledge on chest wall osteosynthesis in polytrauma patients is insufficient, leaving its potential unanswered. Therefore, the objective of this systematic review is to assess the safety and effects of chest wall osteosynthesis compared to conservative treatment on clinical outcomes in adult polytrauma patients.

Breath-hold T2-weighted half-Fourier acquisition single-shot turbo spin echo (HASTE) magnetic resonance imaging (MRI) of the upper abdomen with a slice thickness below 5 mm suffers from high image noise and blurring. The purpose of this prospective study was to improve image quality and accelerate imaging acquisition by using single-breath-hold T2-weighted HASTE with deep learning (DL) reconstruction (DL-HASTE) with a 3 mm slice thickness. MRI of the upper abdomen with DL-HASTE was performed in 35 participants (5 healthy volunteers and 30 patients) at 3 Tesla.
