Haemorrhagic shock remains a leading cause of death in trauma patients. The concept of haematologic damage control is gradually taking place in the management of traumatic haemorrhagic shock. It is based primarily on the early implementation of a quality blood transfusion involving erythrocytes, plasmas and platelets transfusion. Red blood cell transfusion is mainly supported by the oxygen carrier properties of erythrocytes. However, it appears that erythrocytes ability to modulate the bioavailability of nitric oxide (NO) plays a major role in capillary opening and perfusion. Erythrocytes are also actively involved in the processes of hemostasis and coagulation. In this context, it seems difficult to define a threshold of hemoglobin concentration to determine the implementation of a blood transfusion in traumatic haemorrhagic shock.

Secondary brain damageafter traumatic brain injury (TBI) involves oxidative stress, neuroinflammation, apoptosis, and necroptosis and can be reversed by understanding these molecular pathways. The objective of this study was to examine the impact of tasimelteon (Tasi) administration on brain injury through the nuclear factor erythroid 2-related factor 2 (NRF-2)/heme oxygenase-1 (HO-1) and receptor-interacting protein kinase 1 (RIPK1)/receptor-interacting protein kinase 3 (RIPK3)/mixed lineage kinase domain-like (MLKL) pathways in rats with TBI. Thirty-two male Wistar albino rats weighing 300-350 g were randomly divided into four groups: the control group, trauma group, Tasi-1 group (trauma + 1 mg/kg Tasi intraperitoneally), and Tasi-10 group (trauma + 10 mg/kg Tasi intraperitoneally).

Objectives: Balancing oxygen requirements, neurologic outcomes, and systemic complications from transfusions in traumatic brain injury (TBI) patients is challenging. This review compares liberal and restrictive transfusion strategies in TBI patients.
Data Sources: Electronic databases were searched from inception to October 2024.

Blunt abdominal trauma frequently results in visceral injury to either solid or hollow organs; however, injury to the gallbladder is rare. This is most likely due to the anatomical position of the gallbladder, which is well-insulated posterior to the liver and rib cage. Gallbladder injuries can be in the form of avulsion, contusion, or laceration.

Background: In severely injured trauma patients, hypofibrinoginaemia is associated with increased mortality. There is no evidence-based consensus for what constitutes optimal fibrinogen therapy, treatment dose or timing of administration. The aim of this systematic review was to evaluate the effects of early fibrinogen replacement, either cryoprecipitate or fibrinogen concentrate (FgC) on mortality, transfusion requirements and deep venous thrombosis (DVT).

Objectives: Recent research indicates that the plasma lipidome composition may undergo alterations following hemorrhagic stroke. Nevertheless, the causal inference between plasma lipidome and hemorrhagic stroke remains elusive.
Materials And Methods: Exposure data were achieved from a recent Genome-wide Association Study (GWAS) study of 179 lipid species involving 7,174 individuals, while the outcome data were obtained from the FinnGen consortium (R10), including intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and non-traumatic intracranial hemorrhage (nITH).
