BACKGROUND: Previous studies have shown that total cholesterol (TC) levels are associated with stroke outcomes, but sex differences in the association between TC levels, especially a low TC level, and ischemic stroke outcomes are unknown. We aimed to assess the sex differences in stroke outcomes among patients with atherothrombotic infarctions and low TC levels in China. METHODS: This study recruited patients with atherothrombotic infarctions from Tianjin, China, between May 2005 and September 2014...

OBJECTIVE There is a paucity of literature regarding the learning curve associated with performing endoscopic endonasal cranial base surgery. The purpose of this study was to determine to what extent a learning curve might exist for endoscopic endonasal resection in cases of craniopharyngiomas. METHODS A retrospective review was performed for all endoscopic endonasal craniopharyngioma resections performed at Thomas Jefferson University from 2005 to 2015. To assess for a learning curve effect, patients were divided into an early cohort (2005-2009, n = 20) and a late cohort (2010-2015, n = 23)...

BACKGROUND: Agent Orange (AO) is the code name for one of the herbicides and defoliants used in the Vietnam War. Studies conducted thus far show a significant correlation between AO and the occurrence of cardiovascular diseases. But there is little data on the association between AO and stroke, and limited studies have targeted patient groups exposed to AO. METHOD: Bohun medical center Institutional Review Board (IRB) approved the study. (ID: 341) We studied patients with acute ischemic stroke within 7 days of onset in VHS medical center and 4 other general hospitals...

Intracranial hemorrhage (ICH) is a common subtype of stroke with high morbidity and mortality. However, few clinical therapies that can reduce ICH-induced brain injury and promote the recovery outcome in ICH patients are available to improve the recovery from ICH. Given that aquaporin 9 (AQP9) plays a critical role in brain edema after ischemic stroke and traumatic brain injury and is involved in the regulation of angiogenesis, we examined the role of AQP9 in preventing neuronal loss and in neovascularization in the dorsal hippocampus (DH) after ICH...

BACKGROUND: Whether light-to-moderate alcohol consumption is protective against stroke, and whether any association differs by stroke type, is controversial. We conducted a meta-analysis to summarize the evidence from prospective studies on alcohol drinking and stroke types. METHODS: Studies were identified by searching PubMed to September 1, 2016, and reference lists of retrieved articles. Additional data from 73,587 Swedish adults in two prospective studies were included...

BACKGROUND: Herpes zoster (HZ) is caused by reactivation of the latent varicella-zoster virus (VZV). A severe complication of HZ is VZV vasculopathy which can result in ischemic or hemorrhagic stroke. The aims of our study were to assess the risk of stroke after the onset of HZ and to investigate the roles of stroke subtype, HZ location and the time interval between HZ onset and stroke. METHODS: A self-controlled case-series study was performed on a cohort of patients with incident stroke recorded in the German Pharmacoepidemiological Research Database (GePaRD), which covers about 20 million persons throughout Germany...

BACKGROUND AND PURPOSE: Native Hawaiians and other Pacific Islanders (NHOPI) with ischemic stroke have younger age of stroke onset compared with whites. However, ethnic differences in stroke subtypes in this population have been inadequately studied. METHODS: Consecutive young adult patients (aged ≤55 years) who were hospitalized for ischemic stroke between 2006 and 2012 at a tertiary center in Honolulu were studied. Clinical characteristics and stroke subtypes based on pathophysiological TOAST classification (Trial of Org 10172) of NHOPI and Asians were compared with whites...

*Anatol Manaenko and Peng Yang contributed equally to this work.Intracerebral hemorrhage (ICH) represents the deadliest subtype of all strokes. The development of brain edema, a consequence of blood-brain barrier (BBB) disruption, is the most life-threatening event after ICH. Pathophysiological conditions activate the endothelium, one of the components of BBB, inducing rearrangement of the actin cytoskeleton. Upon activation, globular actin assembles into a filamentous actin resulting in the formation of contractile actin bundles, stress fibers...

Indices for the diagnosis of hyperacute cerebral infarction (HACI) and the prediction of prognosis are essential for timely and appropriate management. MicroRNAs (miRNAs) that regulate gene expression following stroke have potential use as prognostic markers of HACI. Here, we explored whether concentrations of circulating miRNAs correlate with clinical outcomes and thus form a system of stroke stratification. Plasma samples from patients with HACI (n = 7) and age-matched healthy volunteers (HVT, n = 4) were screened by microarray to find differentially expressed miRNAs, some of which were further verified by quantitative reverse transcription polymerase chain reaction (qRT-PCR) (HACI:HVT = 33:23)...

Bullous pemphigoid (BP) is an autoimmune blistering skin disease with increasing incidence. BP is associated with neurological disorders, but it has not been established, what subtypes of dementia and stroke are associated with BP, and what is the temporal relation between these diseases. Also, the association between BP and psychiatric disorders is controversial. We conducted a retrospective nationwide study, using the Finnish Care Register for Health Care diagnoses between 1987 and 2013. The study population of 4524 BP patients were compared with 66138 patients with basocellular carcinoma (BCC), neurological and psychiatric comorbid disorders were evaluated for both groups, and associations were estimated by Cox regression and logistic regression analyses...

Subarachnoid hemorrhage (SAH) is a devastating subtype of stroke. Microglial macrophage-inducible C-type lectin (Mincle) receptor launches microglial innate immunity after SAH, and thereby achieves a key step of early cerebral injury in SAH. We previously revealed albumin could improve long-term neurological outcomes after SAH. In this study, we examined the role of microglia-mediated innate immunity in the salutary effects of albumin. SAH was induced by endovascular perforation in rats. We found that albumin can significantly mitigate early neurovascular dysfunction of SAH rats...

BACKGROUND AND PURPOSE: Major cognitive disorder (MND) following vascular events is known as second causes of dementia after Alzheimer's disease (AD). Acute onset MND due to isolated hippocampal infarction has not been recognized as a specific subtype of vascular dementia, and there is no validated criteria for the identification of such cases, either clinically or radiologically. RESULTS: Among 7200 patients with first-ever ischemic stroke, 22 patients (0.3%) showed acute isolated ischemic lesions in the hippocampus...

BACKGROUND: The coexistence of patent foramen ovale (PFO) and sleep apnea syndrome (SAS) might be related to the pathogenesis of cryptogenic stroke (CS). We aimed to determine the prevalence of SAS in patients with cryptogenic stroke and PFO. METHODS: This is a prospective case-control study in which we included ischemic stroke patients consecutively admitted to our hospital's Acute Stroke Unit. Contrast transcranial Doppler (c-TCD) and sleep polygraphy within the first 72 h after stroke onset were performed to detect PFO and SAS...

BACKGROUND AND PURPOSE: There is conflicting evidence for whether or not the incidence of stroke is influenced by the daily temperature. The association between daily temperature and incidence of stroke is largely unknown in Korea. This study attempted to evaluate whether the maximum or minimum daily temperature is associated with increased numbers of strokes and stroke subtypes among Seoul residents. METHODS: We obtained the maximum and minimum daily temperatures in Seoul from the Korean Meteorological Administration between January 2005 and December 2014...

BACKGROUND AND PURPOSE: Little is known about the factors associated with in-hospital mortality following total anterior circulation stroke (TACS). We examined the characteristics and comorbidity data for TACS patients in relation to in-hospital mortality with the aim of developing a simple clinical rule for predicting the acute mortality outcome in TACS. METHODS: A routine data registry of one regional hospital in the UK was analyzed. The subjects were 2,971 stroke patients with TACS (82% ischemic; median age=81 years, interquartile age range=74-86 years) admitted between 1996 and 2012...

Intracranial hemorrhage (ICH) is a common subtype of stroke with high morbidity and mortality. However, few studies have examined the effects of diabetes on the recovery from ICH-induced brain injury. Therefore, we examined the effects of diabetes on protein levels of aquaporins, neuronal loss, angiogenesis, blood brain barrier (BBB) integrity, and neurological deficits following intra-DH collagenase-induced ICH in the hippocampus. We found that diabetic rats exhibited enhanced AQP9 expression in the hippocampus relative to non-diabetic rats, which was associated with increased behavioral deficits...
