Fifty newborn infants of less than 33 weeks' gestation were followed prospectively from birth with serial coagulation and real-time ultrasound studies. A significant association of hypocoagulability in the first four hours of life with subsequent onset or progression of intraventricular or other clinical hemorrhages was documented. Abnormalities included lower values for fibrinogen, platelet count, antithrombin III, and factor VIII with higher values for fibrin monomer and longer Laidlaw whole blood clotting times. These abnormalities tended to correct spontaneously in surviving infants. An association between gestational complications and incidence of hypocoagulability and intracranial hemorrhage (ICH) was noted. Babies of preeclamptic mothers had fewer abnormalities and babies born to mothers with premature rupture of membranes and suspected amnionitis manifested more hypocoagulability and more severe intracranial hemorrhages.

Ultra-Low-Field Portable Brain Magnetic Resonance Imaging in Patients With Cardiac Devices: Current Evidence and Future Directions.
ASAIO J
January 2025
From the Division of Cardiac Surgery, Department of Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland.
The use of cardiac devices, including mechanical circulatory support (MCS), cardiac implantable electronic devices (CIEDs), and pacing wires, has increased and significantly improved survival in patients with severe cardiac failure. However, these devices are frequently associated with acute brain injuries (ABIs) including ischemic strokes, intracranial hemorrhages, seizures, and hypoxic-ischemic brain injury which contribute substantially to morbidity and mortality. Computed tomography (CT) and magnetic resonance imaging (MRI), the standard imaging modalities for ABI diagnosis, can pose significant challenges in this patient population due to the risks associated with patient transportation and the incompatibility of ferromagnetic components of certain cardiac devices with high magnetic field of the MRI.

Chronic subdural haematoma (cSDH) is a common subtype of traumatic brain injury, typically affecting older people living with frailty and multimorbidity. Until now, no published guideline has existed internationally to guide management, perhaps explaining why the care of the older cSDH patient varies between neurosurgical centres. The Improving Care in Elderly Neurosurgery Initiative guideline is the first guideline dedicated to the care of patients with cSDH across the entire patient pathway, from initial presentation through to rehabilitation and discharge after surgery.

Department of Geriatrics and Neurology, Diakonie Hospital Jung Stilling, Siegen, Germany.
Background: Surgical clipping and endovascular coiling are both effective in preventing aneurysmal subarachnoid hemorrhage, but the choice between these interventions remains controversial, leading to treatment disparities across medical centers.
Methods: A systematic review and meta-analysis were conducted, including relevant two-arm clinical trials up to September 2023, sourced from Scopus, PubMed, Web of Science, and the Cochrane Library. Our primary outcomes were complete occlusion rates during mid-term and long-term follow-ups.
Dental Pulp Stem Cells Attenuate Early Brain Injury After Subarachnoid Hemorrhage via miR-26a-5p/PTEN/AKT Pathway.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke with high morbidity, mortality and disability, and early brain injury (EBI) after SAH is crucial for prognosis. Recently, stem cell therapy has garnered significant attention in the treatment of neurological diseases. Compared to other stem cells, dental pulp stem cells (DPSCs) possess several advantages, including abundant sources, absence of ethical concerns, non-invasive procurement, non-tumorigenic history and neuroprotective potential.

This study aims to demonstrate the effect of gamma knife radiosurgery (GKRS) on symptoms, hemorrhage rates, and histopathological changes in patients with cavernous malformations (CMs), regardless of whether the symptomatic lesions are hemorrhagic. This single-center retrospective study evaluated symptomatic patients with single CMs treated with GKRS between 2016 and 2023. The patients' demographic data, presenting symptoms, GKRS radiation dose, complications developed during follow-up (hemorrhage, radiotoxicity), the rate of symptom improvement, and histopathological changes of surgically removed CMs were recorded.
