BACKGROUND Abnormal placental cord insertion (PCI) includes marginal cord insertion (MCI) and velamentous cord insertion (VCI). VCI has been shown to be associated with adverse pregnancy outcomes. This systematic review and meta-analysis aims to determine the association of abnormal PCI and adverse pregnancy outcomes. METHODS Embase, Medline, CINAHL, Scopus, Web of Science, ClinicalTrials.gov...
Using Alzgene-like approaches to investigate susceptibility genes for vascular cognitive impairment.
Vascular cognitive impairment (VCI), including vascular dementia, is the second most common dementia after Alzheimer's disease. Despite its prevalence, the genetic etiology of sporadic VCI is largely unknown. We conducted a systematic review of all published genetic association studies of forms of sporadic VCI prior to 6 July 2012. An initial pool of 229 gene association studies yielded 104 pap...
a r t i c l e i n f o Keywords: Virtual product development Virtual customer integration Co-creation Consumer motives Theory of planned behavior Virtual customer integration (VCI) involves customers throughout all stages of the new product development process. Firms across industries have started to experiment with virtual user integration and expect to utilize their knowledge, creativity, and ...
BACKGROUND Cortical atrophy is a key neuroimaging feature of dementia. However, the role of subcortical gray matter reduction in cognitive impairment has not been explored extensively. OBJECTIVES We examined the risk factors of subcortical structures on neuroimaging and their association with cognitive impairment and dementia. METHODS Data from two studies were used: a subsample from the Ep...
Ensemble methods often produce effective classifiers by learning a set of base classifiers from a diverse collection of the training sets. In this paper, we present a system, voting on classifications from imputed learning sets (VCI), that produces those diverse training sets by randomly removing a small percentage of attribute values from the original training set, and then using an imputation...
PURPOSE To compare patient controlled inhalational induction (PCI) with the most commonly used sevoflurane induction technique, vital capacity inhalational induction (VCI). METHODS Following approval of the Research Ethics Board, 124 outpatients undergoing knee arthroscopy were randomly assigned to receive either PCI or VCI sevoflurane followed by laryngeal mask airway (LMA) insertion and sev...
Background. Transcranial magnetic stimulation (TMS) highlighted functional changes in dementia, whereas there are few data in patients with vascular cognitive impairment-no dementia (VCI-ND). Similarly, little is known about the neurophysiological impact of vascular depression (VD) on deterioration of cognitive functions. We test whether depression might affect not only cognition but also speci...
BACKGROUND Vascular cognitive impairment (VCI) is a heterogeneous entity with multiple aetiologies, all linked to underlying vascular disease. Among these, VCI related to subcortical small vessel disease (SSVD) is emerging as a major homogeneous subtype. Its progressive course raises the need for biomarker identification and/or development for adequate therapeutic interventions to be tested. In...
OBJECTIVES This study sought to assess the ability of a novel virtual coronary intervention (VCI) tool based on invasive angiography to predict the patient's physiological response to stenting. BACKGROUND Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) is associated with improved clinical and economic outcomes compared with angiographic guidance alone. Virtual (v...
BACKGROUND AND PURPOSE Subcortical ischemic vascular disease (SIVD) is a major form of vascular cognitive impairment (VCI) due to small vessel disease. Matrix metalloproteinases (MMPs) are neutral proteases that disrupt the blood-brain barrier and degrade myelin basic protein under conditions of neuroinflammation. Brain tissues and cerebrospinal fluid (CSF) of patients with VCI have increased l...
