Inhibition of α5 GABAA receptors has preventive but not therapeutic effects on isoflurane-induced memory impairment in aged rats.

Neural Regen Res 2019 Jun;14(6):1029-1036

Institute of Pharmacology and Toxicology, Academy of Military Medical Sciences, Beijing, China.

The α5 subunit-containing gamma-amino butyric acid type A receptors (α5 GABAARs) are a distinct subpopulation that are specifically distributed in the mammalian hippocampus and also mediate tonic inhibitory currents in hippocampal neurons. These tonic currents can be enhanced by low-dose isoflurane, which is associated with learning and memory impairment. Inverse agonists of α5 GABAARs, such as L-655,708, are able to reverse the short-term memory deficit caused by low-dose isoflurane in young animals. Read More

Department of Emergency Medicine, Maricopa Medical Center, Phoenix, Arizona.

The acute headache in the emergency department (ED) poses a diagnostic dilemma that may overwhelm providers attempting to weigh the cost of advanced workups against the risk of missing serious pathology. While the majority of headache concerns are benign primary headache disorders, identifying life-threatening secondary causes of headache-which may be broadly categorized into structural, infectious, and vascular causes-is the primary focus of evaluation in the ED. Secondary headaches are associated with a high morbidity and mortality, and require strict scrutiny of the history and physical examination to adequately risk-stratify patients. Read More

Thirty-day readmissions in aneurysmal subarachnoid hemorrhage: A good metric for hospital quality?

Authors:
Isaac Ng Rose Du

J Neurosci Res 2019 Feb 11. Epub 2019 Feb 11.

Department of Neurological Surgery, Brigham and Women's Hospital, Boston, Massachusetts.

Thirty-day readmission rates has been increasingly used by clinicians, hospital administrators, and policy makers as a metric for the quality of care. However, the 30-day readmission rates may be affected by other factors intrinsic to the patient and may not be a good measure of the quality of care provided by the hospital. In this review, we examined the quality of the 30-day readmissions rate as a quality metric for the quality of care provided to patients with aneurysmal subarachnoid hemorrhage (SAH). Read More

RP001 hydrochloride improves neurological outcome after subarachnoid hemorrhage.

J Neurol Sci 2019 Feb 5;399:6-14. Epub 2019 Feb 5.

Neurology, Henry Ford Hospital, Detroit MI-48202, USA. Electronic address:

Subarachnoid hemorrhage (SAH) results in neurological damage, acute cardiac damage and has a high mortality rate. Immunoresponse in the acute phase after SAH plays a key role in mediating vasospasm, edema, inflammation and neuronal damage. The S1P/S1PR pathway impacts multiple cellular functions, exerts anti-inflammatory and anti-apoptotic effects, promotes remyelination, and improves outcome in several central nervous system (CNS) diseases.

Two Diverse Hemodynamic Forces, a Mechanical Stretch and a High Wall Shear Stress, Determine Intracranial Aneurysm Formation.

Transl Stroke Res 2019 Feb 8. Epub 2019 Feb 8.

Department of Molecular Pharmacology, Research Institute, National Cerebral and Cardiovascular Center, 5-7-1 Fujishiro-dai, Suita, Osaka, 565-8565, Japan.

Intracranial aneurysm (IA) usually induced at a bifurcation site of intracranial arteries causes a lethal subarachnoid hemorrhage. Currently, IA is considered as a macrophage-mediated inflammatory disease triggered by a high wall shear stress (WSS) on endothelial cells. However, considered the fact that a high WSS can be observed at every bifurcation site, some other factors are required to develop IAs. Read More

High-Grade Aneurysmal Subarachnoid Hemorrhage: Predictors of Functional Outcome.

World Neurosurg 2019 Feb 5. Epub 2019 Feb 5.

Department of Neurosurgery, University of Louisville, Louisville, Kentucky. Electronic address:

Background: Since the prognosis of high-grade aneurysmal subarachnoid hemorrhage (aSAH), classified as World Federation of Neurological Societies (WFNS) grade IV-V, is generally poor, the functional outcomes of survivors have not been thoroughly explored. The aim of this retrospective cohort study is to determine predictors of functional independence in patients who survive a high-grade aSAH.

Methods: We retrospectively evaluated consecutive aSAH patients admitted to a single institution from January 2000 to April 2015. Read More

Home-Time as a Surrogate Marker for Functional Outcome After Aneurysmal Subarachnoid Hemorrhage.

Stroke 2018 Dec;49(12):3081-3084

From the Department of Neurosurgery, University Hospital Zurich and Clinical Neuroscience Center, University of Zurich, Switzerland (M.N.S., E.K., O.B., L.R.)

Background and Purpose—Commonly used tools to determine functional outcome after aneurysmal subarachnoid hemorrhage (aSAH) have limitations. Time spent at the patient’s home has previously been proposed as a robust outcome measure after ischemic stroke. Here, we set out to validate home-time as an outcome measure after aSAH. Read More

Early dysglycemia and mortality in traumatic brain injury and subarachnoid hemorrhage.

Minerva Anestesiol 2019 Feb 7. Epub 2019 Feb 7.

Australian and New Zealand Intensive Care Research Centre (ANZIC RC), School of Public Health and Preventive Medicine, Monash University, Melbourne, Australia -

Background: Traumatic Brain Injury (TBI) and Sub-Arachnoid Hemorrhage (SAH) are the most common causes of severe acute brain injury in younger Intensive Care Unit (ICU) patients. Dysglycemia (abnormal peak glycemia, glycemic variability, mean glycemia, nadir glycemia) is common in these patients but its comparative outcome associations are unclear.

Methods: In a retrospective, cross-sectional, study of adults admitted to Australian and New Zealand ICUs with TBI and SAH (TBI&SAH) from 2005 to 2015, we studied the relationship between multiple aspects of early (first 24 hours) dysglycemia and mortality and compared TBI and SAH patients with the general ICU population and with each other.

Acute Blood Pressure Management in Neurocritically Ill Patients.

Pharmacotherapy 2019 Feb 7. Epub 2019 Feb 7.

University Hospitals Cleveland Medical Center, Cleveland, OH.

Optimal blood pressure management is controversial in neurocritically ill patients due to conflicting concerns of worsening ischemia with decreased blood pressure versus cerebral edema and increased intracranial pressure with elevated blood pressure. In addition, there is a lack of high-quality evidence regarding optimal blood pressure goals in patients with most of these conditions. This review summarizes guideline recommendations and examines the literature for blood pressure management in patients with ischemic stroke, intracerebral hemorrhage, aneurysmal subarachnoid hemorrhage, traumatic brain injury, and spinal cord injury.

Short-term tranexamic acid treatment reduces in-hospital mortality in aneurysmal sub-arachnoid hemorrhage: A multicenter comparison study.

PLoS One 2019 7;14(2):e0211868. Epub 2019 Feb 7.

Neurosurgical Center Amsterdam, Amsterdam UMC, Univ(ersity) of Amsterdam, Amsterdam, the Netherlands.

Background: Recurrent bleeding is one of the major causes of morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). Antifibrinolytic therapy is known to reduce recurrent bleeding, however, its beneficial effect on outcome remains unclear. The effect of treatment with tranexamic acid (TXA) until aneurysm treatment on clinical outcome is evaluated. Read More

Incidence of Arterial Hypotension in Patients Receiving Peroral or Continuous Intra-arterial Nimodipine After Aneurysmal or Perimesencephalic Subarachnoid Hemorrhage.

Neurocrit Care 2019 Feb 6. Epub 2019 Feb 6.

Department of Anesthesiology, University Hospital Regensburg, Franz-Josef-Strauß-Allee 11, 93053, Regensburg, Germany.

Background: Oral nimodipine is used for prophylaxis and treatment of delayed cerebral ischemia in patients with aneurysmal or perimesencephalic subarachnoid hemorrhage (SAH). In cases of serious refractory cerebral vasospasm, a continuous intra-arterial (IA) infusion of nimodipine (CIAN) may be required to avoid cerebral ischemia. Nimodipine can cause arterial hypotension requiring either a dosage reduction or its discontinuation. Read More
