Relationship between diffusion tensor fractional anisotropy and motor outcome in patients with hemiparesis after corona radiata infarct.
This study examined the relationship between fractional anisotropy (FA) values of magnetic resonance-diffusion tensor imaging (DTI) and motor outcome (1 month after onset) in 15 patients with hemiparesis after ischemic stroke of corona radiata lesions. DTI data were obtained on days 14-18. FA values within the cerebral peduncle were analyzed using a computer-automated method. ⋯ Analysis revealed statistically significant relationships between rFA and upper extremity functions (correlation coefficient=.679 for shoulder/elbow/forearm and .706 for wrist/hand). Although slightly less evident, the relationship between rFA and lower extremity function was also statistically significant (correlation coefficient=.641). FA values within the cerebral peduncle are moderately associated with the outcome of both upper and lower extremity functions, suggesting that DTI may be applicable for outcome prediction in stroke patients with corona radiata infarct.

Dysphagia screening and hospital-acquired pneumonia in patients with acute ischemic stroke: findings from Get with the Guidelines--Stroke.
National guidelines recommend dysphagia screening (DS) before oral intake in stroke patients to reduce hospital-acquired pneumonia (HAP). We examined the relationship between DS and HAP after ischemic stroke. ⋯ HAP occurs in 1 of 17 hospitalized stroke patients and is associated with a greater than 5-fold increase in mortality. DS did not occur in 31.1% of eligible patients, with increased screening among those with more severe strokes and those who developed HAP. The attenuation of the relationship between DS and HAP risk when controlling for NIHSS score suggests the association between screening and pneumonia is confounded by severity. Controlled trials are needed to determine DS effectiveness.

Body mass index and stroke: overweight and obesity less often associated with stroke recurrence.
Although obesity is associated with excess mortality and morbidity, mortality is lower in obese than in normal weight stroke patients (the obesity paradox). Studies now indicate that obesity is not associated with increased risk of recurrent stroke in the years after first stroke. We studied the association between body mass index (BMI) and stroke patient's risk of having a history of previous stroke (recurrent stroke). ⋯ The obesity paradox in stroke can be extended to include also stroke recurrence. Obese and overweight stroke patients had experienced less previous strokes than normal weight stroke patients.

Does small aneurysm size predict intraoperative rupture during coiling in ruptured and unruptured aneurysms?
Aneurysm size is a possible risk factor for intraoperative rupture (IOR) during coiling procedures. We aim to determine if aneurysm size 4 mm or smaller predicts IOR. ⋯ Aneurysm size 4 mm or smaller is a risk factor for IOR in ruptured but not unruptured aneurysms. This additional risk factor should be considered when planning the management of small, ruptured aneurysms.
