Background: The recent introduction of near-infrared spectroscopy has enabled the monitoring of cerebral blood flow in real-time. Previous studies have shown that blood flow velocity is a predictor of cardiovascular disease. We hypothesized that cerebral oxygenation with a change in posture is a predictor for cerebral infarction. We designed a cross-sectional study to investigate the relationship between postural-related changes in cerebral oxygenation and a history of chronic cerebral infarction.
Methods: A total of 100 consecutive participants were enrolled in this study. We evaluated changes in cerebral oxygenation with a change in posture from the supine to the upright position in the bilateral forehead. The association between a decline in cerebral oxygenation and chronic cerebral infarction was analyzed with multiple logistic regression adjusted for covariates.
Results: Cerebral blood oxygenation increased in 52 participants and decreased in 48 participants with a postural change. The prevalence of decreased cerebral oxygenation was 76.3% in participants with chronic cerebral infarction. Multiple logistic regression analysis showed that a decline in cerebral oxygenation upon a postural change was strongly associated with chronic cerebral infarction (adjusted odds ratio: 3.42, = 0.025).
Conclusions: Cerebral blood oxygenation upon a postural change could be a useful predictor for cerebral infarction.

Background: The effect of targeted temperature management (TTM) combined with decompressive craniectomy (DC) on poor-grade aneurysmal subarachnoid hemorrhage (aSAH) has not been previously addressed in the literature. This study aims to investigate the therapeutic outcomes of the combination of TTM and DC in patients with poor-grade aSAH.
Methods: This study represents a secondary analysis of the Multicenter Clinical Research on Targeted Temperature Management of Poor-grade Aneurysmal Subarachnoid Hemorrhage (High-Quality TTM for PaSAH), a multicenter prospective study conducted in China.
Acute Isolated Corpus Callosum Infarction: A Case Report.

Neurology, Sheikh Shakhbout Medical City (SSMC) and Mayo Clinic, Abu Dhabi, ARE.
The corpus callosum is a large subcortical white matter region in the brain that contains fiber connecting both cerebral hemispheres together; it has a rich blood supply; hence, infarction in this region is rare. There are a few reported cases of corpus callosal infarction, and here we present our patient who had a clinical presentation that was not suggestive of corpus callosal infarction. However, an MRI brain confirmed the location, and the patient was managed following the standard stroke treatment, and vascular risk factors were addressed and managed.

Background: Acute ischemic stroke, especially hemorrhage cerebral infarction (HCI), resulted in the leading causes of mortality and long-term disability across populations. However, fewer researches have focused on the risk factors of first admission and recurrence of HCI.
Methods: The study included 1857 patients who underwent cerebral infarction with or without hemorrhagic transformation.

Background: Post-traumatic cerebral infarction (PTCI) is a severe complication resulting from traumatic brain injury (TBI), which can lead to permanent neurological damage or death. The investigation of the factors associated with PTCI and the establishment of predictive models are crucial for clinical practice.
Methods: We made a retrospective analysis of clinical data from 1484 TBI patients admitted to the Neurosurgery Department of a provincial hospital from January 2018 to December 2023.
Electroacupuncture Pretreatment Reduces Ischemic Brain Injury by Inhibiting the Lactate Production and Its Derived Protein Lactylation Formation.

Acupuncture and Tuina School, Chengdu University of Traditional Chinese Medicine, Chengdu, China.
Aim: Given that electroacupuncture (EA) pretreatment inhibits lactate production and lactate-derived lysine lactation (Kla) aggravates ischemic brain injury, we aimed to investigate whether the formation of Kla protein is involved in EA pretreatment to alleviate ischemic brain injury.
Methods: EA was performed on the Baihui acupoint (GV20) of male C57BL/6J mice before receiving the permanent middle cerebral artery occlusion (pMCAO) surgery. Western blot and immunofluorescent staining were used to observe neuronal survival, astrocyte activation, and protein Kla levels, and the lactate levels in ischemic brains were assayed with a commercial kit.
