Sepsis-associated encephalopathy (SAE) is common in septic patients, characterized by acute and long-term cognitive impairment, and is associated with higher mortality. This study aimed to identify SAE-related biomarkers and evaluate their diagnostic potential. We analyzed three SAE-related sequencing datasets, using two as training sets and one as a validation set. Weighted Gene Co-expression Network Analysis and four machine learning methods-Elastic Net regression, LASSO, random forest, and XGBoost-were employed, dentifying 18 biomarkers with significant expression changes. External validation and in vitro experiments confirmed the differential expression of these biomarkers. These findings provide insights into SAE pathogenesis and suggest potential therapeutic targets.

Background: Although surviving sepsis campaign (SSC) guidelines are the standard for sepsis and septic shock management, outcomes are still unfavourable. Given that perfusion pressure in sepsis is heterogeneous among patients and within the same patient; we evaluated the impact of individualized hemodynamic management via the transcranial Doppler (TCD) pulsatility index (PI) on mortality and outcomes among sepsis-induced encephalopathy (SIE) patients.
Methods: In this prospective, single-center randomized controlled study, 112 patients with SIE were randomly assigned.

Background: Sepsis-associated encephalopathy (SAE) represents a severe complication of sepsis, substantially elevating both mortality and healthcare costs for patients. Gastrodin (GAS), a principal bioactive constituent of Gastrodia elata Blume, is neuroprotective in various neurological disorders, including ischemic stroke, epilepsy, Alzheimer's disease, and neuropathic pain. In this study, we sought to investigate whether GAS could serve as a protective agent against SAE.

Sepsis is characterised by dysregulated immune responses to infection, leading to multi-organ dysfunction and high rates of mortality. With increasing survival rates in recent years long-term neurological and psychiatric consequences have become more apparent in survivors. Many patients develop sepsis associated encephalopathy (SAE) which encompasses the profound but usually transient neuropsychiatric syndrome delirium but also new brain injury that emerges in the months and years post-sepsis.

Aims: This study investigated the protective role of Annexin A1 (ANXA1) in sepsis-associated encephalopathy (SAE) by examining its effects on brain vascular endothelium and blood-brain barrier (BBB) integrity.
Methods: Mice were divided into four groups: wild type (WT), cecal ligation and puncture (CLP), ANXA1 knockout (ANXA1[-/-]), and ANXA1(-/-) with CLP. Neurobehavioral changes were assessed using the Y-maze test, while BBB integrity was evaluated through Evans blue dye (EBD) staining and permeability tests with fluorescein isothiocyanate (FITC)-dextran.
