Reduced speech intelligibility has been observed in Parkinson’s disease (PD), ataxic dysarthria, multiple sclerosis (MS) and in individuals who have suffered a cerebral vascular accident (CVA). Data support the effectiveness of the Lee Silverman Voice Treatment (LSVT) on the improvement of vocal function and speech intelligibility in PD. Today, only a small percentage of patients with chronic n...

A hemiparetic and aphasic patient, 3 days after acute traumatic transection of the left internal carotid artery requiring life-saving total embolic occlusion, revealed ipsilateral increased peripheral hemispheric 99mTc-HMPAO activity. Ten days postocclusion, HMPAO peripheral cortical flow normalized as hemiparesis and aphasia significantly cleared. The initial lateralized HMPAO hyperactivity pa...

A Markov model is constructed for studying the counterparty risk in a CDS contract. The ‘wrong-way risk’ in this model is accounted for by the possibility of the common default of the reference name and of the counterparty. A dynamic copula property as well as affine model specifications make pricing and calibration very efficient. We also consider the issue of dynamically hedging the CVA with ...

Tail-biting trellises are defined on a circular time axis and can have a smaller number of states than equivalent conventional trellises. Existing circular Viterbi algorithms (CVAs) on the tail-biting trellis are non-convergent and sub-optimal. In this study, we show that the net path metric of each tail-biting path is lower-bounded during the decoding process of the CVA. This property can be a...

Materials and methods Practice registry lists at ten public health centres were screened for patients with cerebrovascular accident (CVA) between July and December 2012. Patients aged ≥18 years with recorded diagnosis of CVA either radiographically or by referring physician were recruited. Patients with transient ischaemic attack, traumatic brain injury or isolated nerve palsies were excluded. ...

abstract arterial ischemic stroke defines as a new focal neurologic deficit that lasted 24 hours or longer. stroke is relatively rare in children and incidence of cerebrovascular disease is 1 per 4000 in neonates and 1 per 7000 to 1 per 70000 in older children (1 month to 18 years). protein s deficiency is one of the causes of the stroke in children. major manifestations of protein s deficiency...

BACKGROUND High LDL-cholesterol (LDL-C) and glucose levels are risk factors for ischemic heart disease (IHD) in middle-aged diabetic individuals; however, the risk among the elderly, especially the very elderly, is not well known. The aim of this study was to identify factors that predict IHD and cerebrovascular attack (CVA) in the elderly and to investigate their differences by age. METHODS ...

Several studies have reported on gender differences in the risk of periprocedural complications after percutaneous coronary intervention (PCI) chronic total occlusions (CTOs). The purpose this meta-analysis is to evaluate CTO-PCI based gender. A literature search was conducted for reporting CTO PCI Clinical endpoints included embolic cerebral vascular accident (CVA), tamponade requiring pericar...

We study counterparty risk on CDS in a Markov chain model of two reference credits, the firm underlying the CDS and the CDS protection seller. More specifically, we consider a Markov chain copula model in which wrong way risk is represented by the possibility of joint defaults between the counterpart and the firm. In this set-up we derive semi-explicit formulas for most quantities of interest w...

A canonical variance analysis (CVA) biplot can visually portray a oneway MANOVA. Both techniques are subject to the assumption of equal class covariance matrices. In the application considered, very small sample sizes resulted in some singular class covariance matrix estimates and furthermore it seemed unlikely that the assumption of homogeneity of covariance matrices would hold. Analysis of di...
