Neurologic symptom severity after a recent noncardioembolic stroke and recurrent vascular risk

Prior intracerebral hemorrhage and white matter hyperintensity burden on recurrent stroke risk

Prior intracerebral hemorrhage (ICH) is associated with increased risk of ischemic stroke. Since white matter hyperintensity (WMH) is associated with ischemic stroke and ICH, this study aimed to evaluate the relationship between ICH and the risk of recurrent stroke by WMH severity. From a prospective multicenter database comprising 1454 noncardioembolic stroke patients with cerebral small-vessel disease, patients were categorized by presence or absence of prior ICH and WMH severity: mild-moderate WMH (reference); advanced WMH; ICH with mild-moderate WMH; and ICH with advanced WMH. Among patients with ICH, the association with stroke outcomes by WMH burden was further assessed. The primary endpoint was ischemic stroke and hemorrhagic stroke. The secondary endpoint was major adverse cardiovascular events (MACE): stroke/coronary heart disease/vascular death. During the mean 1.9-year follow-up period, the ischemic stroke incidence rate per 100 person-years was 2.7, 4.0, 2.5, and 8.1 in increasing severity, and the rate of hemorrhagic stroke was 0.7, 1.3, 0.6, and 2.1, respectively. The risk of ischemic stroke was higher in ICH with advanced WMH (adjusted HR 2.62; 95% CI 1.22−5.60) than the reference group, while the risk of hemorrhagic stroke trended higher (3.75, 0.85–16.53). The risk of MACE showed a similar pattern in ICH with advanced WMH. Among ICH patients, compared with mild WMH, the risk of ischemic stroke trended to be higher in advanced WMH (HR 3.37; 95% CI 0.90‒12.61). Advanced WMH was independently associated with an increased risk of hemorrhagic stroke (HR 33.96; 95% CI 1.52−760.95). Given the fewer rate of hemorrhagic stroke, the risk of hemorrhagic stroke might not outweigh the benefits of antiplatelet therapy for secondary prevention.

Systematic Review and Meta-Analysis of Home-Based Rehabilitation on Improving Physical Function Among Home-Dwelling Patients With a Stroke

OBJECTIVE

To evaluate the effects of home-based rehabilitation on improving physical function in home-dwelling patients after a stroke.

DATA SOURCES

Various electronic databases, including PubMed, Cumulative Index to Nursing and Allied Health, Embase, the Cochrane Central Register of Controlled Trials, and 2 Chinese data sets (ie, Chinese Electronic Periodical Services and China Knowledge Resource Integrated) were searched for studies published before March 20, 2019.

STUDY SELECTION

Randomized controlled trials conducted to examine the effect of home-based rehabilitation on improving physical function in home-dwelling patients with a stroke and published in English or Chinese were included. In total, 49 articles in English (n=23) and Chinese (n=26) met the inclusion criteria.

DATA EXTRACTION

Data related to patient characteristics, study characteristics, intervention details, and outcomes were extracted by 2 independent reviewers.

DATA SYNTHESIS

A random-effects model with a sensitivity analysis showed that home-based rehabilitation exerted moderate improvements on physical function in home-dwelling patients with a stroke (g=0.58; 95% CI, 0.45∼0.70). Moderator analyses revealed that those patients with stroke of a younger age, of male sex, with a first-ever stroke episode, in the acute stage, and receiving rehabilitation training from their caregiver showed greater improvements in physical function.

CONCLUSIONS

Home rehabilitation can improve functional outcome in survivors of stroke and should be considered appropriate during discharge planning if continuation care is required.
