ReviewMechanism and Therapy of Brain Edema after Intracerebral Hemorrhage.
Intracerebral hemorrhage (ICH) is a subtype of stroke with a severe high mortality and disability rate and accounts for about 10-15% of all strokes. The oppression and destruction by hematoma to brain tissue cause the primary brain injury. The inflammation and coagulation response after ICH would accelerate the formation of brain edema around hematoma, resulting in a more severe and durable injury. Currently, treatments for ICH are focusing on the primary injury including reducing intracranial hypertension, blood pressure control, and rehabilitation. There is a short-of-effective medical treatment for secondary inflammation and reducing brain edema in ICH patients. So, it is very important to study on the relationship between brain edema and ICH. ⋯ This review mainly discusses the pathology and mechanism of brain edema, the effects of brain edema on ICH, and the methods of treating brain edema after ICH.

Comparative StudyThe Effect of Age on Characteristics and Mortality of Intracerebral Hemorrhage in the Oldest-Old.
Incidence of acute intracerebral hemorrhage (ICH) increases with age, but there is a lack of information about ICH characteristics in the oldest-old (age ≥85 years). In particular, there is a need for information about hematoma volume, which is included in most clinical scales for prediction of mortality in ICH patients. Many of these scales also assume that, independent of ICH characteristics, the oldest-old have a higher mortality than younger elderly patients (age 65-74 years). However, supporting evidence from cohort studies is limited. We investigated ICH characteristics of oldest-old subjects compared to young (<65 years), young-old (65-74 years) and old-old (75-84 years) subjects. We also investigated whether age is an independent mortality predictor in elderly (age ≥65 years) subjects with acute ICH. ⋯ Oldest-old subjects with acute supratentorial ICH have higher admission hematoma volume than young and young-old subjects but do not differ for other ICH characteristics. When taking into account confounding from ICH characteristics, risk of in-SU and 1-year mortality in elderly subjects with acute supratentorial ICH does not differ across age categories. Our findings question use of age as an independent criterion for stratification of mortality risk in elderly subjects with acute ICH.

Multicenter Study Comparative Study Observational StudyEndovascular Treatment in Patients with Persistent Internal Carotid Artery Occlusion after Intravenous Tissue Plasminogen Activator: A Clinical Effectiveness Study.
There has been no large-scale trial comparing endovascular treatment (add-on EVT) after intravenous tissue plasminogen activator (IV tPA) and IV tPA alone in acute ischemic stroke (AIS) caused by internal carotid artery occlusion (ICAO). We aimed at investigating the effectiveness and safety of add-on EVT after IV tPA in AIS patients with ICAO. ⋯ Compared to an IV tPA alone, add-on EVT can improve clinical outcomes in patients with symptomatic ICAO within 4.5 h of onset without a significant increase of symptomatic hemorrhage.

Multicenter StudyDysphagia in Patients with Acute Ischemic Stroke: Early Dysphagia Screening May Reduce Stroke-Related Pneumonia and Improve Stroke Outcomes.
Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. ⋯ Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability.

Cortical Superficial Siderosis in Memory Clinic Patients: Further Evidence for Underlying Cerebral Amyloid Angiopathy.
Cerebral amyloid angiopathy (CAA) is associated with many cases of spontaneous symptomatic lobar intracerebral haemorrhage in older individuals and is emerging as an important contributor to cognitive impairment. Cortical superficial siderosis (cSS) is an increasingly recognized haemorrhagic neuroimaging manifestation of CAA. We sought to investigate its prevalence and its association with underlying CAA among memory clinic patients. ⋯ Our data provide further evidence supporting the hypothesis that cSS is a manifestation of advanced CAA in memory clinic populations. Future longitudinal studies should explore any direct effect of cSS on cognition or haemorrhage risk and disease progression.
