Subarachnoid hemorrhage due to rupture of intracranial aneurysms has a poor outcome, making this disease being the social problem. Inflammation evoked by the increase in intracranial pressure and the clot in the subarachnoid space after the onset of SAH exacerbates neuronal death and vasospasm, resulting in the poor outcome and severe aftereffects. Here, FROUNT mediates CCR2 and CCR5 signaling as an intracellular molecule binding to these chemoattractant receptors which facilitate the migration of inflammatory cells, such as macrophages, in situ to trigger inflammation there. ⋯ In this condition, disulfiram ameliorated the death of animals after the onset of subarachnoid hemorrhage in rats. In addition, disulfiram suppressed both the two major events after subarachnoid hemorrhage, the neuronal death in hippocampus and vasospasm. The pharmacological inhibition of CCR2 and CCR5 signaling by disulfiram could thus be the therapeutic strategy to improve the outcome of subarachnoid hemorrhage.

Despite effective treatment for aneurysmal subarachnoid hemorrhage (aSAH), delayed cerebral ischemia (DCI) is a common complication that has a significant impact on the recovery of neurologic function. In this study, we aimed to investigate the efficacy of hyperbaric oxygen therapy (HBOT) in the rehabilitation treatment of aSAH. ⋯ In summary, early HBOT reduced the DCI rate in aSAH patients and consequently promoted improvement of the executive control function of ANT.

Treatment outcomes of octogenarians with aneurysmal subarachnoid hemorrhage (aSAH) are often considered poor. With ongoing advancements and experience in endovascular technology, we sought to evaluate the outcomes of octogenarians treated for aSAH in the second post-International Subarachnoid Aneurysm Trial (ISAT)/Barrow Ruptured Aneurysm Trial (BRAT) decade. ⋯ Neurologic outcomes of octogenarian patients with aSAH are improving in the second post-trial decade, particularly given the preponderance of endovascular treatment. Baseline functional status and comorbidities of octogenarians should be considered in addition to the Hunt-Hess grade in prognostication.

Accurate volumetric assessment of spontaneous aneurysmal subarachnoid hemorrhage (aSAH) is a labor-intensive task performed with current manual and semiautomatic methods that might be relevant for its clinical and prognostic implications. In the present research, we sought to develop and validate an artificial intelligence-driven, fully automated blood segmentation tool for subarachnoid hemorrhage (SAH) patients via noncontrast computed tomography (NCCT) scans employing a transformer-based Swin-UNETR architecture. ⋯ Our Swin UNETR-based model offers significant advances in the automated segmentation of blood in SAH patients on NCCT images. Despite the computational demands, the model operates effectively on standard hardware with a user-friendly interface, facilitating broader clinical adoption. Further validation across diverse datasets is warranted to confirm its clinical reliability.
