Induction of anaesthesia in intracranial surgery, especially for vascular diseases, must minimize haemodynamic changes: blood pressure and cerebral blood flow must not be increased to a high degree. Our work compares increases in blood pressure and in the speed of cerebral blood flow during endotracheal intubation in two groups of patients, who received propofol or thiopentone for the induction of anaesthesia. We studied 30 patients, without intracranial diseases, who underwent lumbar slipped disk surgery. Half of the patients received thiopentone and curare before intubation and the other half propofol and curare. Increase in blood pressure after intubation was lower with propofol than with thiopentone in a statistically significant way. Also the increase in the speed of cerebral blood flow, measured with doppler technique, was lower when induction with propofol was used, though not statistically relevant.

Objectives: Cardiac biomarkers are useful for the diagnostic and prognostic assessment of myocardial injury (MI) and heart failure. By measuring specific proteins released into the bloodstream during heart stress or damage, these biomarkers help clinicians detect the presence and extent of heart injury and tailor appropriate treatment plans. This study aims to provide robust biological variation (BV) data for cardiac biomarkers in athletes, specifically focusing on those applied to detect or exclude MI, such as myoglobin, creatine kinase-myocardial band (CK-MB) and cardiac troponins (cTn), and those related to heart failure and cardiac dysfunction, brain natriuretic peptide (BNP) and N-terminal brain natriuretic pro-peptide (NT-proBNP).

Introduction: Immune checkpoint inhibitors (ICI) have improved the therapeutic arsenal in outpatient oncology care; however, data on necessity of hospitalizations associated with immune-related adverse events (irAEs) are scarce. Here, we characterized hospitalizations of patients undergoing ICI, from the prospective cohort study of the immune cooperative oncology group (ICOG) Hannover.
Methods: Between 12/2019 and 06/2022, 237 patients were included.

Background: Stress hyperglycemia ratio (SHR) has been linked to prognosis of cerebrovascular diseases. Nevertheless, the association between SHR and severe disturbance of consciousness (DC) and mortality among patients with cerebral infarction remains explored. This study seeks to assess the predictive potential of SHR for severe DC and mortality among patients with cerebral infarction.

A total of 7 patients with type 1 infratentorial superficial siderosis(iSS-1)in Memory Clinic at Huashan Hospital, Fudan University from March 2019 to March 2023 were respectively collected to analyze the clinical characteristics and treatment, and followed up for 12 months. There were 7 patients, 2 males and 5 females, aged 56 (49-60) years. The 4 patients who underwent cognitive assessment had varying degree of cognitive impairment, with 2 patients exhibiting severe executive function impairment.

Aim: Branch atheromatous disease (BAD), characterized by the occlusion of perforating branches near the orifice of a parent artery, often develops early neurological deterioration because the mechanisms underlying BAD remain unclear. Abnormal wall shear stress (WSS) is strongly associated with endothelial dysfunction and plaque growth or rupture. Therefore, we hypothesized that computational fluid dynamics (CFD) modeling could detect differences in WSS between BAD and small-vessel occlusion (SVO), both of which result from perforating artery occlusion/stenosis.
