BACKGROUND Vertebral artery (VA) dissection (VAD) has been described following neck injury and can be associated with stroke, but the causal association with cervical spine manipulation therapy (cSMT) is controversial. The standard treatment for VAD is antithrombotic medical therapy. To highlight the considerations of an endovascular approach to VAD, we present a critical case of bilateral VAD ...

BACKGROUND AND PURPOSE Considerable clinical and radiological overlap between vascular dementia (VaD) and Alzheimer disease (AD) often makes the diagnosis difficult. Diffusion-tensor imaging studies showed that fractional anisotropy (FA) could be a useful marker for white matter changes. This study aimed to identify regional FA changes to identify a biomarker that could be used to differentiate...

Real time magnetic resonance imaging (rtMRI) enables direct video capture of the moving vocal tract concurrent with audio signal providing valuable data for speech research. We consider a multimodal approach to voice activity detection (VAD) in the rtMRI recording that uses audio signal as well as MRI image sequence. The degraded quality of the audio recorded in the scanner motivates this multi...

The aim of the study was to systematically evaluate effect of CentriMag heart pump (Thoratec Corporation) as temporary ventricular assist device (VAD) and part of extracorporeal membrane oxygenation (ECMO) system on outcomes in patients with cardiac or cardiac-respiratory failure. A systematic search was conducted in five databases for the period 2003 to 2012. Fifty-three publications with data...

BACKGROUND AND PURPOSE Recent studies have shown that cognitive deficits are present during the years preceding a diagnosis of vascular dementia (VaD). The aims of this study were to (1) extend previous research by examining whether cognitive deficits are already present 6 years before diagnosis, and (2) examine the strength of the association between cognitive performance and a future VaD diag...

We studied the plasma chain-breaking antioxidants alpha carotene, beta carotene, lycopene, Vitamin A, Vitamin C, Vitamin E and a measure of total antioxidant capacity, TAC, in 79 patients with Alzheimer's disease (AD), 37 patients with vascular dementia (VaD), 18 patients with Parkinson's disease and dementia (PDem), and 58 matching controls, together with 41 patients with Parkinson's disease (...

Unexplained bleeding episodes are associated with ventricular assist devices (VAD) and can occur in part due to acquired von Willebrand syndrome (AVWS). AVWS is characterised by loss of high molecular weight (HMW) multimers of von Willebrand factor (VWF) and decreased ratios of collagen binding capacity and ristocetin cofactor activity to VWF antigen. Loss of multimers can occur as VWF is subje...

Cardiac tamponade is an uncommon disorder in pediatric patients. We report a case of cardiac tamponade secondary to accumulation of cerebrospinal fluid due to ventriculo-atrial derivation (VAD) disfunction. An 11-month-old girl was assisted because of respiratory distress and tachycardia, without fever. She had a ventriculoatrial derivation, because of hydro-cephalus since two month earlier. Th...

Voice activity detection (VAD) plays an important role on the performance of speech processing systems. Recently, more and more works focused on the statistical model-based VAD algorithms have been presented in literature, which make a decision of speech and nonspeech based on the likelihood ratio (LR). However, all the statistical models used in those algorithms are unable to exactly describe ...

Vascular dementia (VaD) is the second most common subtype of dementia in Western countries (Desmond, 1996) and, overall, may be the most common subtype of dementia in the world (Henderson, 1994). Furthermore, the recognition of some major risk factors of cerebrovascular disease makes VaD a form of ‘preventable senility ’ (Hachinski, 1992). The last decade has seen a major re-evaluation of the c...
