BACKGROUND: The presence of white matter hyperintensity (WMH) is related to poor long-term outcomes in stroke patients. However, the long-term outcome is unknown in patients with both large artery atherosclerosis (LAA) and WMH. METHODS: We investigated the impact of WMH on long-term outcome in patients with LAA. Consecutive patients in a prospective stroke registry were included. Patients were followed for a median of 7.7 years (interquartile range, 5.6-9.7). The degree of WMH was assessed by Fazekas grade on fluid-attenuated inversion recovery images...

: We compared the short-term, middle-term and long-term primary outcomes between thrombolysis and nonthrombolysis therapy in acute ischemic stroke (AIS) patients. Medical records were collected from patients suffered from AIS between 2010 and 2013 and allocated into either the intravenous recombinant tissue plasminogen activator (as rt-PA group) treatment, or non-rt-PA treatment group (as control group). The primary outcomes included a proportion of patients with favorable outcome [as defined with a modified Rankin Scale (mRS) of 0-1], functional independence (mRS of 0-2) or with bad outcome (mRS of 5-6) at 3, 6 and 12 months and the overall mortality...

Cerebral ischemic stroke is usually caused by a temporary or permanent decrease in blood supply to the brain. Despite general progress in diagnosis and treatment, the prognosis of stroke is still unsatisfactory, and more detailed potential mechanisms are needed to investigate underlying the pathological process. Here, we showed that serum angiotensin-converting enzyme (ACE) concentration was positively correlated with infarct volume after acute ischemic stroke (AIS). Moreover, using a permanent middle cerebral artery occlusion rat model, we indicated for the first time that increased ACE expression in response to AIS was regulated by the ERK/NF-κB pathway in peri-infarct regions...

BACKGROUND Our previous study found that lower lymphocyte-to-monocyte ratio (LMR) is an independent risk factor of clinical outcome of acute ischemic stroke (AIS). However, whether lower LMR is independently associated with adverse prognosis of AIS treated with thrombolysis has not been determined. In this study, we explored the relationship between LMR and prognosis of AIS treated with thrombolysis. MATERIAL AND METHODS We retrospectively enrolled 108 patients treated with thrombolysis. LMR was calculated according to lymphocyte count and monocyte count on admission...

BACKGROUND AND PURPOSE: Recent studies suggest that patients with large-vessel ischemic strokes (large-vessel occlusion [LVO]) with favorable imaging may benefit from mechanical thrombolysis even when treated outside the standard 6-hour window. However, many patients in these studies presented with unknown times of onset. We compare outcomes in thrombectomy patients treated at less than versus greater than 6 hours from last known well (LKN), and evaluate whether "unknown time of onset" alters prognosis...

BACKGROUND: Stroke is rarely seen in children, but it is a major cause of morbidity and mortality. Therefore, there is a need for inexpensive and noninvasive diagnostic methods for estimating the prognosis. Although the prognostic importance of hematological parameters in acute ischemic stroke were reported in adult studies, there is a lack in pediatric ages. The aim of the study is to investigate the relationship between hematological parameters and prognosis of acute ischemic stroke in children...

Cell death is indispensable in the physiology, pathology, growth, development, senility and death of an organism. In recent years, the identification of a highly regulated form of necrosis, known as necroptosis, has challenged the traditional concept of necrosis and apoptosis, which are two major modes of cell death. This novel manner of cell death is similar in form to necrosis in terms of morphological features, and it can also be regulated in a caspase‑independent manner. Therefore, necroptosis can be understood initially as a combination of necrosis and apoptosis...

Thrombolysis with tissue plasminogen activator is the mainstay in the treatment of acute stroke. Reducing the delay of thrombolysis treatment improves patient prognosis and reduces the incidence of complications. Variable telestroke regimens have improved the availability of stroke thrombolysis, especially in rural settings, where neurologists are not readily available. In the drip-and-ship strategy, stroke thrombolysis is initiated in a peripheral hospital and the patient is then transferred to a tertiary care unit...
