Rapid and generic identification of influenza A and other respiratory viruses with mass spectrometryMajchrzykiewicz-Koehorst, J.A. (author), Heikens, E. (author), Trip, H. (author), Hulst, A.G. (author), de Jong, A.L. (author), Viveen, M.C. (author), Sedee, N.J.A. (author), van der Plas, J. (author), Coenjaerts, F.E.J. (author), Paauw, A. (author)The rapid identification of existing and emerging respiratory viruses is crucial in combating outbreaks and epidemics. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a rapid and reliable identification method in bacterial diagnostics, but has not been used in virological diagnostics. Mass...article 2015

Coenen, P. (author), Kingma, I. (author), Boot, C.R.L. (author), Bongers, P.M. (author), van Dieën, J.H. (author)The trade-off between feasibility and accuracy of measurements of physical exposure at the workplace has often been discussed, but is unsufficiently understood. We therefore explored the effect of two low-back loading measurement tools with different accuracies on exposure estimates and their associations with low-back pain (LBP). Low-back...article 2015

(author), Bruijnzeel-Koomen, C.A. (author), Pasmans, S.G.M.A. (author)Background: About 10 to 20% of children in West European countries have atopic dermatitis (AD), often as part of the atopic syndrome. The full atopic syndrome also consists of allergic asthma, allergic rhinitis and food allergy. Treatment approaches for atopic dermatitis and asthma include intermittent anti-inflammatory therapy with...article 2014

Perez, J. (author), de Looze, M.P. (author), Bosch, T. (author), Neumann, W.P. (author)This methodological paper presents a novel approach to predict operator's mechanical exposure and fatigue accumulation in discrete event simulations. A biomechanical model of work-cycle loading is combined with a discrete event simulation model which provides work cycle patterns over the shift resulting in a load-time trace for the entire shift....article 2014

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

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?'.
