Maintaining cfDNA concentrations is vital for immune homeostasis and preventing inflammatory responses. Understanding cfDNA release and clearance is essential for using cfDNA as a biomarker in clinical diagnostics.

Dyneins are classified into three major subfamilies, namely cytoplasmic, intraflagellar-transport (IFT), and ciliary dyneins, based on their intracellular localization and functions. Recently, several near-atomic resolution structures have been reported for cytoplasmic/IFT dyneins.

- The study analyzed outcomes for pediatric patients with blunt liver and spleen injuries (BLSI) treated at hospitals with and without pediatric intensive care units (PICUs) between 2008 and 2019.
- Among the 1401 patients, 30-day mortality rates were lower in hospitals with PICUs (0.7%) compared to those without (1.3%), and also compared to adult ICUs.
- Overall, while adverse events were infrequent, the findings suggested that treatment in hospitals with PICUs may lead to better outcomes for pediatric patients with BLSI.
Background: Multidose iodinated contrast media (ICM) injectors have shown promise in reducing ICM waste. This study aims to evaluate the impact of patient volume on ICM waste reduction in multidose injectors.
Methods: CT studies performed over one-year period with a multidose injector at our emergency CT unit.
