Background: High levels of catecholamines are cardiotoxic and associated with stress-induced cardiomyopathies. Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

Intestinal perforations lead to a high risk of sepsis-associated morbidity and multi-organ dysfunctions. A perforation allows intestinal contents (IC) to enter the peritoneal cavity, causing abdominal infections. Right- and left-sided perforations have different prognoses in humans, but the mechanisms associated with different cecum and colon perforations remain unclear.

Chimeric antigen receptor T (CAR-T) cell therapy, an emerging personalized immunotherapy for various haematologic malignancies, autoimmune diseases and other conditions, involves the modification of patients' T cells to express a chimeric antigen receptor that recognizes tumour or autoimmune cell antigens, allowing CAR-T cells to destroy cancerous and other target cells selectively. Despite remarkable clinical improvements in patients, multiple adverse effects have been associated with CAR-T cell therapy. Among the most recognized adverse effects are cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome and tumour lysis syndrome.

Aquaporins (AQPs) are membrane proteins facilitating water and other small solutes to be transported across cell membranes. They are crucial in maintaining cellular homeostasis by regulating water permeability in various tissues. Moreover, they regulate cell migration, signaling pathways, inflammation, tumor growth, and metastasis.

Background: Plasma oxidized lipids are intimately linked to immune regulation as bioactive mediators. However, it is not clear whether they are related to the progression of sepsis-associated acute kidney injury (SA-AKI) and the effect of continuous renal replacement therapy (CRRT). This study intends to explore the changes in certain oxidized lipid during CRRT treatment and their correlation with the immune microenvironment and prognosis by analyzing plasma oxidative lipidomics.
