Aneurysmal Subarachnoid Hemorrhage Onset Alters Pyruvate Metabolism in Poor-Grade Patients and Clinical Outcome Depends on More: A Cerebrospinal Fluid Metabolomic Study.

ACS Chem Neurosci 2018 Dec 6. Epub 2018 Dec 6.

Cerebral metabolism alterations influence cerebrospinal fluid (CSF) composition, and is sensitive to brain injury. In subarachnoid hemorrhage (SAH) patients, Fisher scale, Hunt-Hess scale and World Federation of Neurological Societies (WFNS) grading scales evaluating SAH severity are inadequate to predict long-term outcome; therefore, in an effort to determine metabolite pattern disparity and discover corresponding biomarkers, we designed an untargeted CSF metabolomic research covering a board range of metabolites of SAH patients with different severity and outcome. The present study demonstrated SAH altered cerebrospinal fluid metabolome involving carbohydrate, lipid and amino acids metabolism. Read More

Muse Cells and Aortic Aneurysm.

Adv Exp Med Biol 2018 ;1103:273-291

Division of Cardiovascular Surgery, Tohoku University Graduate School of Medicine, Sendai, Japan.

The aorta is a well-organized, multilayered structure comprising several cell types, namely, endothelial cells (ECs), vascular smooth muscle cells (VSMCs), and fibroblasts, as well as an extracellular matrix (ECM), which includes elastic and collagen fibers. Aortic aneurysms (AAs) are defined as progressive enlargements of the aorta that carries an incremental risk of rupture as the diameter increases over time. The destruction of the aortic wall tissue is triggered by atherosclerosis, inflammation, and oxidative stress, leading to the activation of matrix metalloproteinases (MMPs), and inflammatory cytokines and chemokines, resulting in the loss of the structural back bone of VSMCs, ECM, and ECs.

Abdominal aortic aneurysms (AAA) are characterized by extensive extracellular matrix (ECM) fragmentation and inflammation. However, the mechanisms by which these events are coupled thereby fueling focal vascular damage are undefined. Here we report through single-cell RNA-sequencing of diseased aorta that the neuronal guidance cue netrin-1 can act at the interface of macrophage-driven injury and ECM degradation. Read More

A Large Database Analysis of Rates of Aneurysm Screening, Elective Treatment, and Subarachnoid Hemorrhage in Patients With Polycystic Kidney Disease.

Neurosurgery 2018 Nov 26. Epub 2018 Nov 26.

Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan.

Background: Professional societies provide conflicting guidelines on aneurysm screening in patients with polycystic kidney disease (PKD), and the rate of subarachnoid hemorrhage (SAH) is poorly understood.

Objective: To evaluate screening, elective treatment, and the rate of SAH in patients with known PKD.

Methods: We examined longitudinally linked claims data from a large private insurer, identifying screening, elective treatment, aneurysmal subarachnoid hemorrhage (aSAH) and secured aneurysmal SAH (saSAH) in 2004 to 2014 amongst patients with known PKD. Read More

The Prognostic Significance of a Cast Fourth Ventricle in Ruptured Aneurysm Patients With Intraventricular Hemorrhage in the Barrow Ruptured Aneurysm Trial (BRAT).

Neurosurgery 2018 Nov 23. Epub 2018 Nov 23.

Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona.

Background: Ruptured aneurysms causing intraventricular hemorrhage (IVH) are associated with high morbidity. The presence of blood that completely fills the fourth ventricle (cast fourth ventricle, CFV) is thought to be particularly ominous, but studies documenting the outcome of such cases are lacking.

Objective: To investigate the outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH) and CFV. Read More

Is there a role for lumbar puncture in early detection of subarachnoid hemorrhage after negative head CT?

Intern Emerg Med 2018 Nov 24. Epub 2018 Nov 24.

Emergency Department, Turku University Hospital, Turku, Finland.

To investigate the role of lumbar puncture (LP) after a negative head computed tomography (CT) when ruling out subarachnoid hemorrhage (SAH) within 24 h of symptom onset. In a single-center, retrospective cohort study, we studied a consecutive series of patients from 2011 to 2015. All patients underwent CT or CT following LP to rule out SAH. Read More
