Characterisation of the diagnostic window of serum glial fibrillary acidic protein for the differentiation of intracerebral haemorrhage and ischaemic stroke.
The rapid differentiation between intracerebral haemorrhage (ICH) and ischaemic stroke (IS) using biomarker testing would allow the prehospital, cause-specific management of stroke patients. Based on single measurements made during the acute phase of stroke, the value of serum glial fibrillary acidic protein (GFAP) was reported to be higher in ICH patients than in IS patients. The aim of the present study was to characterise the diagnostic window of serum GFAP for differentiating between ICH and IS. ⋯ The time window between 2 and 6 h after stroke onset is best for using GFAP to differentiate between ICH and IS. In the very early phase (i.e. <2 h), sensitivity for detecting ICH is low, thus hampering the application of GFAP as a near-patient test in the prehospital phase.

Randomized Controlled Trial Multicenter StudyVery early mobilisation and complications in the first 3 months after stroke: further results from phase II of A Very Early Rehabilitation Trial (AVERT).
Interventions that may reduce the number and severity of potentially harmful post-stroke complications are desirable. This study explored whether very early and frequent mobilisation (VEM) affected complication type (immobility/stroke related), number and severity. ⋯ Interventions that promote recovery and reduce complications may consequently reduce length of stay. The larger phase III trial currently underway may shed light on whether increasing mobilisation reduces complications after stroke.

Multicenter Study Comparative StudyRisk of symptomatic intracerebral hemorrhage in patients treated with intra-arterial thrombolysis.
In intra-arterial (IA) thrombolysis trials, higher rates of symptomatic intracerebral haemorrhage (sICH) were found than in trials with intravenous (IV) recombinant tissue plasminogen activator (tPA); this observation could have been due to the inclusion of more severely affected patients in IA thrombolysis trials. In the present study, we investigated the rate of sICH in IA and combined IV + IA thrombolysis versus IV thrombolysis after adjusting for differences in clinical and MRI parameters. ⋯ In this series, IA and IV + IA thrombolysis is associated with an increased sICH risk as compared to IV thrombolysis, and this risk is independent of differences in baseline parameters such as age, initial NIHSS score or pretreatment lesion size.

Meta AnalysisAssociation analysis of genes involved in the maintenance of the integrity of the extracellular matrix with intracranial aneurysms in a Japanese cohort.
An association between versican (CSPG2), perlecan (HSPG2), fibrillin 2 (FBN2) and collagen 4A1 (COL4A1) gene variants and intracranial aneurysms (IA) has been reported in 2 studies analyzing Dutch IA patients. The aim of this study was to verify these associations in a Japanese IA population. In addition, a meta-analysis on the association of these genes and IA for the combined Dutch and Japanese populations was performed. ⋯ By analyzing HSPG2, CSPG2, FBN2 and COL4A1, we were able to replicate the association of CSPG2 and show that there is a trend for HSPG2 towards association in the Japanese IA population by means of a meta-analysis combining the Dutch and Japanese results. The association of FBN2 and COL4A1 could not be replicated in the Japanese IA population.
