A comparison of the results of arterial embolization for bleeding and non-bleeding gastroduodenal ulcers.

Background: Although some authors have advocated the practice of arterial embolization for angiographically negative acute hemorrhage from gastroduodenal ulcers, this technique remains controversial.

Purpose: To compare the results of arterial embolization for bleeding (BU) and non-bleeding (NBU) gastroduodenal ulcers.

Material And Methods: Transcatheter embolization was performed in 57 patients (39 men, 18 women, mean age 69.

Head positioning and risk of pneumocephalus, air embolism, and hemorrhage during subthalamic deep brain stimulation surgery.

Purpose: The objective of the present study was to evaluate the risk of pneumocephalus, venous air embolism (VAE), and intracranial hemorrhage in subthalamic nucleus (STN) deep brain stimulation (DBS) patients operated in the strict supine (head and body flat) position.

Methods: This was a retrospective review of clinical records and brain imaging of patients who underwent STN DBS between January 2007 and June 2009 at the University of Kansas Medical Center.

Results: A total of 61 patients underwent 114 lead implantations (53 staged bilateral and 8 unilateral).

Diagnostic utility of cerebral white matter integrity in early Alzheimer's disease.

We compared white matter integrity with brain atrophy in healthy controls and participants with very mild dementia (Clinical Dementia Rating 0 vs. 0.5) from the Brain Aging Project, a longitudinal study of aging and memory at the University of Kansas Medical Center.

Cardiorespiratory fitness and preserved medial temporal lobe volume in Alzheimer disease.

Exercise and cardiorespiratory (CR) fitness may moderate age-related regional brain changes in nondemented (ND) older adults. The relationship of fitness to Alzheimer disease (AD)-related brain change is understudied, particularly in the hippocampus, which is disproportionately affected in early AD. The role of apolipoprotein E4 (apoE4) genotype in modulating this relationship is also unknown.

Impact of APOE on the healthy aging brain: a voxel-based MRI and DTI study.

Neuroimaging studies of apolipoprotein E (ApoE4) have implicated its association with brain atrophy in Alzheimer's disease. To date, few studies have used automated morphological analysis techniques to assess ApoE4-related brain structure change in both gray and white matter in nondemented older adults. Nondemented (CDR = 0, n = 53) subjects over 60 had MRI, diffusion tensor imaging, and neurocognitive assessments.
