(author)Altered respiratory rate is one of the first symptoms of medical conditions that require timely intervention, e.g., sepsis or opioid-induced respiratory depression. To facilitate continuous respiratory rate monitoring on general hospital wards a contactless, non-invasive, prototype monitor was developed using frequency modulated continuous wave...article 2016

Haas, F.J.L.M. (author), Schutgens, R.E.G. (author), Kluft, C. (author), Biesma, D.H. (author)Introduction. The exclusion of deep venous thrombosis (DVT) by pre-test probability (PTP) and D-dimer in the elderly is safe, but has a low specificity. There is increasing interest in the diagnostic role of thrombin generation in patients with thrombosis. We evaluated the value of thrombin generation in the exclusion of DVT, especially in...article 2011

(author), TNO Kwaliteit van leven (author)Alzheimer's disease (AD) is the most prevalent form of dementia and the number of cases is expected to increase exponentially worldwide. Three highly penetrant genes (AβPP, PSEN1, and PSEN2) explain only a small number of AD cases with a Mendelian transmission pattern. Many genes have been analyzed for association with non-Mendelian AD, but the...article 2010

(author)Background: Yersinia pestis (Y. pestis) is a zoonotic bacterium mainly circulating among rodents and their fleas. Transmission to humans can cause bubonic, pneumonic or septicemic plague with a high case-fatality rate. Therefore, rapid and reliable diagnostic tools are crucial. The objective of this study was to assess the inter-laboratory...article 2008

van Buuren, S. (author), TNO Kwaliteit van Leven (author)The standard deviation score (SDS) is a powerful tool for screening for growth-related problems. However, referral rules of the type 'if SDS(Y)<d, then refer' (for some constant d) are not optimal for answering the question: 'Does this child with measurement Y belong to the reference or to the diseased population?'. If the growth standard for...article 2008

Jacobusse, G. (author), van Buuren, S. (author), TNO Kwaliteit van Leven (author)Developmental indicators that are used for routine measurement in The Netherlands are usually chosen to optimally identify delayed children. Measurements on the majority of children without problems are therefore quite imprecise. This study explores the use of computerized adaptive testing (CAT) to monitor the development of young children. CAT...article 2007
