Common lipidomic signatures across distinct acute brain injuries in patient outcome prediction.

Lipidomic alterations have been associated with various neurological diseases. Examining temporal changes in serum lipidomic profiles, irrespective of injury type, reveals promising prognostic indicators. In this longitudinal prospective observational study, serum samples were collected early (46 ± 24 h) and late (142 ± 52 h) post-injury from 70 patients with ischemic stroke, aneurysmal subarachnoid hemorrhage, and traumatic brain injury that had outcomes dichotomized as favorable (modified Rankin Scores (mRS) 0-3) and unfavorable (mRS 4-6) three months post-injury.

Soluble Urokinase-Type Plasminogen Activator Receptor and Inflammatory Biomarker Response with Prognostic Significance after Acute Neuronal Injury - a Prospective Cohort Study.

Aneurysmal subarachnoid hemorrhage (aSAH), ischemic stroke (IS), and traumatic brain injury (TBI) are severe conditions impacting individuals and society. Identifying reliable prognostic biomarkers for predicting survival or recovery remains a challenge. Soluble urokinase type plasminogen activator receptor (suPAR) has gained attention as a potential prognostic biomarker in acute sepsis.

Localization and Network Connectivity of Lesions Causing Limb Ataxia in Patients With Stroke.

Background And Objectives: Ataxia is primarily considered to originate from the cerebellum. However, it can manifest without obvious cerebellar damage, such as in anterior circulation stroke, leaving the mechanisms of ataxia unclear. The aim of this study was to investigate whether stroke lesions causing limb ataxia localize to a common brain network.

Brain plasticity and neuroinflammatory protein biomarkers with circulating MicroRNAs as predictors of acute brain injury outcome - A prospective cohort study.

Background: Brain recovery mechanisms after injuries like aneurysmal subarachnoid hemorrhage (aSAH), ischemic stroke (IS), and traumatic brain injury (TBI) involve brain plasticity, synaptic regeneration, and neuroinflammation. We hypothesized that serum levels of the p75 neurotrophic receptor (p75NTR) and associated signaling proteins, as well as differentially expressed (DE) microRNAs, could predict recovery outcomes irrespective of injury type.

Methods: A prospective patient cohort with ischemic stroke (IS, n = 30), aneurysmal subarachnoid hemorrhage (aSAH, n = 31), and traumatic brain injury (TBI, n = 13) were evaluated (total n = 74).

Brain Plasticity Modulator p75 Neurotrophin Receptor in Human Urine after Different Acute Brain Injuries-A Prospective Cohort Study.

Acute brain injuries (ABIs) pose a substantial global burden, demanding effective prognostic indicators for outcomes. This study explores the potential of urinary p75 neurotrophin receptor (p75NTR) concentration as a prognostic biomarker, particularly in relation to unfavorable outcomes. The study involved 46 ABI patients, comprising sub-cohorts of aneurysmal subarachnoid hemorrhage, ischemic stroke, and traumatic brain injury.

A comprehensive p75 neurotrophin receptor gene network and pathway analyses identifying new target genes.

P75 neurotrophic receptor (p75NTR) is an important receptor for the role of neurotrophins in modulating brain plasticity and apoptosis. The current understanding of the role of p75NTR in cellular adaptation following pathological insults remains blurred, which makes p75NTR's related signaling networks an interesting and challenging initial point of investigation. We identified p75NTR and related genes through extensive data mining of a PubMed literature search including published works related to p75NTR from the past 20 years.

Rapid improvement of a complex migrainous episode with sodium valproate in a patient with CADASIL.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited disease of small arteries caused by mutations in the Notch3 gene. Complex migrainous episodes, such as acute confusional migraine, status migrainosus with persisting aura, and "CADASIL coma" have been described in patients with CADASIL. However, there are few descriptions of effective treatment of such episodes.

Three cases of superficial siderosis of the central nervous system and review of the literature.

Superficial siderosis of the central nervous system results from chronic or intermittent hemorrhage into the subarachnoid space that causes hemosiderin deposition in subpial layers of the brain and the spinal cord leading to neuronal damage. Patients present with progressive and debilitating symptoms that typically include adult-onset slowly progressive cerebellar gait ataxia and sensorineural hearing impairment. Regardless of extensive investigations, the origin of the hemorrhage is often not clear.

Effectiveness of primary and comprehensive stroke centers: PERFECT stroke: a nationwide observational study from Finland.

Background And Purpose: Previous studies show better outcomes for patients with stroke receiving care in stroke units, but many different stroke unit criteria have been published. In this study, we explored whether stroke centers fulfilling standardized Brain Attack Coalition criteria produce better patient outcomes than hospitals without stroke centers.

Methods: We did an observational register-linkage study of all patients with ischemic stroke treated in Finland between 1999 and 2006.

Ophthalmologic findings in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy: a cross-sectional study.

Objective: To determine the ophthalmologic findings, especially the nature of retinal vascular changes, and their clinical significance in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a disease that causes migraine, recurrent strokes, and finally subcortical vascular dementia.

Design: Cross-sectional study.

Participants: Thirty-eight CADASIL patients (19 to 61 years old; 20 in a prestroke group, 15 in a stroke group, and 3 in a dementia group), all with the R133C NOTCH3 mutation and including one homozygous patient, underwent a detailed ophthalmologic examination.

Arterioles of the lenticular nucleus in CADASIL.

Background And Purpose: In cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) the arteriopathy leads to recurrent infarcts in cerebral white matter (WM) and deep gray matter (GM), whereas cortex is spared. To assess the pathogenesis of deep GM infarcts, we analyzed structural changes in arterioles of the lenticular nucleus (LN) in 6 CADASIL patients.

Methods: Five elderly and one 32-year-old deceased CADASIL patients were studied.
