Sepsis represents a major contributor to mortality among critically ill patients, imposing a substantial economic strain on health-care systems. The uncontrolled inflammatory response during sepsis development, often leading to multiorgan failure and death, remains a challenge despite advances in antibiotics and supportive care. Factors such as antibiotic resistance, noninfectious causes, and delays in treatment initiation contribute to the complexity of managing sepsis. This review explores alternative treatment strategies focusing on the ameliorative efects of widely consumed phytochemicals and their cellular and molecular mechanisms in various in vitro and in vivo sepsis models. Preemptive administration of phytochemicals before sepsis onset appears efective, emphasizing their potential as adjunct or complementary therapeutic agents for critically ill sepsis patients. As a consequence, phytochemicals can be included in treatment regimens to enhance overall efectiveness and expedite the healing process.

Background: Sepsis-induced acute lung injury (ALI) is a severe clinical condition accompanied with high mortality. Tangeretin, which is widely found in citrus fruits, has been reported to exert antioxidant and anti-inflammatory properties. However, whether tangeretin protects against sepsis-induced ALI and the potential mechanisms remain unclear.

Background: To assess the value of combined Monocyte Distribution Width (MDW) and Procalcitonin (PCT) detection in diagnosing and predicting neonatal sepsis outcomes.
Methods: This retrospective study, conducted from January 2022 to December 2023.A retrospective analysis of 39 neonatal sepsis and 30 non-infectious systemic inflammatory response syndrome (SIRS) cases was conducted.

Sepsis is a leading cause of death worldwide, with most patient mortality stemming from lingering immunosuppression in sepsis survivors. This is due in part to immune dysfunction resulting from monocyte exhaustion, a phenotype of reduced antigen presentation, altered CD14/CD16 inflammatory subtypes, and disrupted cytokine production. Whereas previous research demonstrated improved sepsis survival in Ticam2 mice, the contribution of TICAM2 to long-term exhaustion memory remained unknown.

Sepsis-induced acute lung injury (ALI) is a complex and life-threatening condition characterized by excessive inflammatory responses, ferroptosis, and oxidative stress. A comprehensive investigation and effective therapeutic strategies are crucial for managing this condition. In this study, we established in vivo sepsis models using lipopolysaccharide (LPS) in wild-type (WT) mice and triggering receptor expressed on myeloid cells 2 (TREM2) knockout (TREM2-KO) mice to assess lung morphology, oxidative stress, and ferroptosis.

The angiopoietin (Ang)-Tie axis, critical for endothelial cell function and vascular development, is a promising therapeutic target for treating vascular disorders and inflammatory conditions like sepsis. This study aimed to enhance the binding affinity of recombinant Ang1 variants to the Tie2 and explore their therapeutic potential. Structural insights from the Ang1-Tie2 complex enabled the identification of key residues within the Ang1 receptor binding domain (RBD) critical for Tie2 interaction.
