This prospective cohort study designed to assess the effect of folic acid supplementation in pregnancy on the risk of preeclampsia (PE) took place in Ottawa, ON and Kingston, ON, Canada, from September 1, 2002 to August 31, 2008. Pregnant women, less than 20 weeks gestational age were recruited and delivered in the Ottawa region and the Kingston General Hospital. Demographic characteristics of ...

INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "Biosignal Interpretation: Advanced Methods for Studying Cardiovascular and Respiratory Systems". BACKGROUND Hypertensive pregnancy disorders affect 6 - 8 percent of all pregnancies and can result in severe complications for both the mother and the fetus. OBJECTIVES The aim of this study was to imp...

AIM To examine the potential value of previously identified biomarkers using proteomics in early screening for preeclampsia (PE). METHODS 24 blood samples from women who subsequently developed PE and 48 from uncomplicated pregnancies were obtained at 11-13 weeks and analysed after delivery. Cystatin-C, sVCAM-1, and Pappalysin-1 were quantified by ELISA. Maternal characteristics and medical hi...

OBJECTIVE To examine an individualized approach to patients with primary hyperparathyroidism (PHPT) in an effort to identify factors that would differentiate patients who can be treated with radioguided parathyroidectomy (RP) from those that require more extensive parathyroid exploration (PE) using intraoperative parathyroid hormone (IOPTH) measurement and to compare rates of recurrent and pers...

BACKGROUND Patient awareness of venous thromboembolism (VTE) and thromboprophylaxis is essential for their safety. In this study, we evaluated patients' awareness of VTE and their perceptions of thromboprophylaxis. METHODS We administered a cross-sectional survey to patients hospitalized at the King Abdulaziz Medical City, Riyadh, Saudi Arabia. RESULTS Of 190 patients approached, 174 comple...

Yellow nail syndrome (YNS) can be associated with a pleural effusion (PE) but the characteristics of these patients are not well defined. We performed a systematic review across four electronic databases for studies reporting clinical findings, PE characteristics, and most effective treatment of YNS. Case descriptions and retrospective studies were included, unrestricted by year of publication....

1 Motivations In machine learning, the standard measure of accuracy for models is the prediction error (PE), i.e. the expected loss on future examples. We consider here the i.i.d. regression or classification setups, where future examples are assumed to be independently sampled from the distribution that generated the training set. When the data distribution is unknown, PE cannot be computed. T...

A method was established to quickly determine the content of antioxidants in polyethylene by Fourier transform infrared spectroscopy. By analyzing FTIR spectra antioxidant Irganox 1076 and PE, characteristic peak PE determined be absorption at 1738cm-1. According standard curve antioxidant, had a good linear relationship with intensity its peak, regression coefficient equation 0.97363. The rela...

BACKGROUND The Wisconsin Card Sorting Test (WCST) is a widely used neuropsychological test for assessing executive functions. However, the lack of culture-specific norms has often limited clinical interpretation of performance on the WCST. The aims of this study were to establish adult norms for the WCST in Taiwan, and to understand the development of performance on the WCST among age groups. ...
