Cerebellar edema can block aqueducts and the fourth ventricle and cause hydrocephalus and, in severe cases, herniation of cerebellar tonsils in the 1 2 3 4 2 2 2 2 5 6 2 foramen magnum, causing sudden death [3]. Numerous studies have reported that advanced age, low Glasgow Coma Scale (GCS) scores, and the development of hydrocephalus are substantial risk factors for adverse outcomes [3][4][5][6]. Both ischemic and hemorrhagic infarctions can result in cerebellar stroke, which is highly correlated with long-term hypertension and the use of anticoagulants or antiplatelets. ...

In the present study, muscle loss was assessed using ultrasound as a decrease in the RFCSA of ≥ 10% to define muscle wasting, and muscle wasting was predictive of prolonged hospital stay in critically ill patients with acute brain injury. Comparison of study results is difficult because there is no consensus on the optimal measurement protocol for muscle ultrasound, and image quality can be affected by factors related to the practitioner and the patient [56]. To more precisely characterize skeletal muscle wasting, integration of different parameters may be necessary. ...
... Consequently, NRF2 accumulates in the nucleus and activates the expression of cytoprotective genes via the ARE complex [81]. Furthermore, kinase proteins, including PI3K-AKT, protein kinase C (PKC), AMP-activated protein kinase (AMPK), and mitogen-activated protein kinases (MAPKs), which are activated in the brain by both acute and chronic exercise [93][94][95], promote NRF2 phosphorylation and increase its stability and subsequent transcriptional activity [83][84][85], seeking to maintain brain redox balance [96]. ...

... Both CRP and fibrinogen are critical factors that occur during the acute phase response to inflammation and serve as key acute-phase proteins (46, 47). Activation of the coagulation system is widely acknowledged to be initiated by inflammation, resulting in an increase in prothrombin and antifibrinolytic factor levels (48,49). In contrast, elements within the coagulation system, including fibrinogen or fibrin, can independently trigger the onset of the inflammatory process and contribute to the development of subsequent tissue damage downstream (50). ...
