OBJECTIVES To assess the diagnostic accuracy of placental growth factor (PlGF) and ultrasound parameters to predict delivery of a small-for-gestational-age (SGA) infant in women presenting with reduced symphysis-fundus height (SFH). METHODS This was a multicenter prospective observational study recruiting 601 women with a singleton pregnancy and reduced SFH between 24 and 37 weeks' gestation ...
Invasive ventilation is associated with both pulmonary and non-pulmonary complications. There has been a renewed interest in the use of negative pressure ventilation (NPV) for various medical conditions to minimise the complications associated with positive pressure ventilation. The routine use of NPV in an ICU setting still requires further studies and research. In this article, the authors re...
The NPV technique measures the present value of the future cash flows that a project will produce. A positive NPV means that the investment should increase the value of the firm and lead to maximizing shareholder wealth. A positive NPV project provides a return that is more than enough to compensate for the required return on the investment. Thus, using NPV as a guideline for capital investment...
Background: The prognosis and management of patients with chronic hepatitis B depend on the amount and progression of the liver fibrosis. Liver biopsy is currently the gold standard for staging of fibrosis and histological activity, but it is poor tolerated. Noninvasive methods are now used increasingly to reduce the need for liver biopsy. Our aim is to validate simpler model, consisting of rou...
Although consumer financial decision making has attracted renewed attention from marketing researchers, issues of consumer decumulation of retirement wealth have remained relatively unexplored. Research on decumulation presents an interesting problem for both behavioral and quantitative marketing researchers; it is a choice problem with large stakes, multiple sources of uncertainty, and difficu...
The rationale for using NPV for project evaluation appears weaker than ever. Authoritative texts in attempting to extend NPV by the inclusion of options, strategy and games far from enriching the model present evermore loosely argued rationales that are becoming contradictory. A brief review helps to understand how this state of affairs has arisen and how future analysis might develop. As an ad...
This paper focuses on inconsistencies arising from the use of NPV and CAPM for capital budgeting. It shows that (i) CAPM capital budgeting decision-making based on disequilibrium NPV is deductively inferred by the Capital Asset Pricing Model, (ii) the use of the disequilibrium NPV is widespread in finance both as a decision rule and as a valuation tool, (iii) the disequilibrium NPV does not gua...
INTRODUCTION The aim of this study was to externally validate the Cham score for the prediction of bacteraemia in emergency department (ED) patients with non-hospital acquired pneumonia. MATERIALS AND METHODS This is a secondary analysis of a dataset collected to identify independent predictors of bacteraemia in adult ED patients with non-hospital acquired pneumonia. The primary outcome of in...
The receiver operating characteristic (ROC) curve, the positive predictive value (PPV) curve and the negative predictive value (NPV) curve are three measures of performance for a continuous diagnostic biomarker. The ROC, PPV and NPV curves are often estimated empirically to avoid assumptions about the distributional form of the biomarkers. Recently, there has been a push to incorporate group se...
