Serum soluble lectin ‐like oxidized low‐density lipoprotein receptor‐1 as a biomarker of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage

There is a substantial elevation in serum sLOX ‐1 levels after aSAH. There is an intimate correlation of serum sLOX‐1 levels with hemorrhagic severity. There is an independent association of serum sLOX‐1 levels with delayed cerebral ischemia. AbstractObjectiveDelayed cerebral ischemia (DCI) greatly contributes to the high morbidity and mortality of aneurysmal subarachnoid hemorrhage (aSAH) patients. Expression of lectin ‐like oxidized low‐density lipoprotein receptor‐1 (LOX‐1) was substantially raised in the basilar arterial wall of SAH rabbits. We attempted to ascertain the relationship between serum soluble LOX‐1 (sLOX‐1) levels and the occurrence of DCI after aSAH.Materials and methodsWe enrolled 125 aSAH patients and 125 healthy controls. Serum sLOX ‐1 levels were quantified using commercial enzyme‐linked immunosorbent assay kit. The relationship between sLOX‐1 levels and DCI was analyzed utilizing the multivariate logistic regression analysis.ResultsSerum sLOX ‐1 levels were significantly higher in stroke patients than in controls (median: 1,450.2 vs. 445.7 pg/ml,p   1,450.2 pg/ml, WFNS scores and modified Fisher scores were the independent predictors of DCI. Under receiver operating characteristic curve, serum sLOX‐1 levels exhibited a significant discriminatory capability (area under curve 0.825, 95% confidence interval 0.747–0.887). The predictive powe r of serum sLOX‐1 levels was similar to those of WFNS scores ...

Background: In the treatment of aneurysmal subarachnoid hemorrhage (aSAH), microsurgical clipping, and endovascular therapy (EVT) with coiling are modalities for securing the ruptured aneurysm. Little data is available regarding associated readmission rates. We sought to determine whether readmission rates differed according to treatment modality for ruptured intracranial aneurysms. Methods: The Nationwide Readmissions Database (NRD) was used to identify adults who experienced aSAH and underwent clipping or EVT.

AbstractTranslational genomics represents a broad field of study that combines genome and transcriptome-wide studies in humans and model systems to refine our understanding of human biology and ultimately identify new ways to treat and prevent disease. The approaches to translational genomics can be broadly grouped into two methodologies, forward and reverse genomic translation. Traditional (forward) genomic translation begins with model systems and aims at using unbiased genetic associations in these models to derive insight into biological mechanisms that may also be relevant in human disease. Reverse genomic translation...

Semin Neurol DOI: 10.1055/s-0040-1702942Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical–radiologic diagnosis that affects children and adolescents, but it is much more frequently reported in adults. Clinically, patients present with severe and commonly recurrent thunderclap headaches. Typical precipitating triggers include vasoactive substances, serotonergic agents, and the postpartum period. There may be associated neurologic complications at presentation or in the weeks following, such as convexity subarachnoid hemorrhage, stroke, cerebral edema, cervical artery dissection (CeAD), and seizures. A...

The primary aim of this prospective pilot study was to assess feasibility of implementing goal-oriented attentional self-regulation (GOALS) training in Slovenia with patients with multiple cognitive deficits after acquired brain injury in acute phase of recovery. Seven patients with acquired brain injury (i.e. stroke, traumatic brain injury, and subarachnoid hemorrhage) with a mean postinjury time of 4.3 months (SD = 1.25) and mean age of 34.5 years (SD = 18.6) were recruited for the study. The group program consisted of 10 sessions twice a week and included cognitive strategy training, social skills training, and psychoed...

Time-critical acute ischemic conditions such as ST-elevation myocardial infarction and acute ischemic stroke are staples in Emergency Medicine practice. While timely reperfusion therapy is a priority, the resultant acute ischemia/reperfusion injury contributes to significant mortality and morbidity. Among therapeutics targeting ischemia/reperfusion injury (IRI), remote ischemic conditioning (RIC) has emerged as the most promising. RIC, which consists of repetitive inflation and deflation of a pneumatic cuff on a limb, was first demonstrated to have protective effect on IRI through various neural and humoral mechanisms. It...

ConclusionsThe SPICE multicenter study will investigate 1-year outcomes, ethical issues, as well as care pathways of acute stroke patients requiring invasive ventilation in the ICU. Gathered data will delineate human resources and facilities needs for adequate management. The identification of prognostic factors at the acute phase will help to identify patients who may benefit from prolonged intensive care and rehabilitation.Trial registration: NCT03335995.

AbstractBackgroundAneurysmal subarachnoid hemorrhage (SAH) as a serious type of stroke is frequently accompanied by a so-called initial thunderclap headache. However, the occurrence of burdensome long-term headache following SAH has never been studied in detail so far. The aim of this study was to determine the prevalence and characteristics of long-term burdensome headache in good-grade SAH patients as well as its relation to health-related quality of life (HR-QOL).MethodsAll SAH cases treated between January 2014 and December 2016 with preserved consciousness at hospital discharge were prospectively interviewed regarding...

Authors: Wali Y, Kini V, Yassin MA Abstract Background/Objective: Stroke is a potentially fatal complication of sickle cell disease (SCD). Transcranial Doppler (TCD) is useful at identifying increased risk of stroke in children with SCD and vasospasm after subarachnoid hemorrhage. The main aim of this study was to determine the proportion of patients with SCD in the Gulf region who are at a high risk of stroke, as determined by TCD.Methods: This multicenter (Oman, Qatar, and UAE), descriptive, cross-sectional study in patients (aged 2-16 years) with SCD included a baseline visit, 1 follow-up visit for patients with...
