Recently, the usefulness of near-infrared spectroscopy-based cerebral oximetry in extremely preterm infants to prevent death or severe brain injury was evaluated in a study called SafeBoosC-III (N = 1601). In this study, the incidence of both outcomes was similar between the cerebral oximetry and the control group. In a previous smaller study called SafeBoosC-II (N = 166), there was a borderline significant advantage for cerebral oximetry. There is therefore a highly significant (p = 0.010) difference between the two outcomes. What could be the reason for the difference? One major difference was that many centres were not familiar with cerebral oximeters in the new study compared with the old study. This could be a reason for the discrepancy. We conclude that cerebral oximetry should not be disregarded as a method of neuromonitoring in neonatology.

Aim: The aim was to define reference ranges for cerebral oxygen saturation (crSO-ROOT) during immediate transition after birth in stable neonates.
Methods: In a prospective observational study, the crSO-ROOT was continuously measured in neonates during the first 15 min after birth. The neonatal sensor was placed on the head and fixed with a bandage.

Background: Cerebral autoregulation is a robust regulatory mechanism that stabilizes cerebral blood flow in response to reduced blood pressure, thereby preventing cerebral ischaemia. Scientists have long believed that cerebral autoregulation also stabilizes cerebral blood flow against increases in intracranial pressure, which is another component that determines cerebral perfusion pressure. However, this idea was inconsistent with the complex pathogenesis of normal pressure hydrocephalus, which includes components of chronic cerebral ischaemia due to mild increases in intracranial pressure.

Objective: The clinical importance of individualized blood pressure management in optimizing cerebral perfusion during cardiac surgery has been well established. However, consensus on blood pressure goals is lacking. The authors studied the associations between cerebral autoregulation metrics, hemodynamic parameters, and postoperative outcomes, and hypothesized that increased time of mean arterial pressure (MAP) below the lower limit of autoregulation (LLA) is associated with major morbidity and mortality (MMOM) incidence.

Introduction: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disease and screening to detect pulmonary arteriovenous malformations (PAVMs) is important to prevent complications. In adults, transthoracic contrast echocardiogram (TTCE) is used to screen PAVMs. In children, a conservative screening method seems to be sufficient to rule out major PAVMs and prevent them from PAVM-related complications.

Objective: To identify clinicopathologic and genomic features associated with brain metastasis after resection of lung adenocarcinoma (LUAD) and to evaluate survival after brain metastasis.
Methods: Patients who underwent complete resection of stage I-IIIA LUAD between 2011 and 2020 were included. A subset of patients had broad-based panel next-generation sequencing performed on their tumors.
