OBJECTIVES To examine the cost-effectiveness of a quantitative D-dimer assay for the evaluation of patients with suspected pulmonary embolism (PE) in an urban emergency department (ED). METHODS The authors analyzed different diagnostic strategies over pretest risk categories on the basis of Wells criteria by using the performance profile of the ELISA D-dimer assay (over five cutoff values) an...

Of all groundwater pollution sources, septic systems are the second largest source of groundwater nitrate contamination in USA. This study investigated shallow groundwater (SGW) nutrient dynamics in septic areas at the northern part of the Lower St. Johns River Basin, Florida, USA. Thirty-five SGW-monitoring wells, located at nine different urban areas served by septic systems, were used to col...

(February 1, 2008) Recent advances in nanotechnology permit fabrication of complex nanostructures with special electronic and optical properties reflecting dimensional confinement on a nanometer scale, e.g. multiple quantum wells and core-shell structures.4–7 The essential building blocks of such structures are alternating layers of different semiconducting materials, acting as “wells” and “bar...

An integrated domestic well sampling and "susceptibility assessment" programme was undertaken in the Republic of Ireland from April 2008 to November 2010. Overall, 211 domestic wells were sampled, assessed and collated with local climate data. Based upon groundwater physicochemical profile, three clusters have been identified and characterised by source type (borehole or hand-dug well) and loca...

AIM To describe the contribution of forensic anthropology to the recovery, analysis, and identification of victims from the 1991-1995 war in Croatia recovered in wells. METHODS From 1996 to the present, human remains of a total of 61 individuals have been recovered from 13 wells. Six wells contained the remains of a single individual, one well contained the remains of 2 individuals, and 6 wel...

BACKGROUND Clinical assessment of suspected deep venous thrombosis (DVT) should be based on systematically evaluated evidence. PURPOSE To determine whether clinical findings, risk scores, and physicians' empirical judgments affect the likelihood of detecting DVT on definitive testing. DATA SOURCES MEDLINE, EMBASE, CINAHL, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Con...

The present work provides hydrochemical and stable isotope data and their interpretations for 54 springs and 20 wells, monitored from 2002 to 2006, in the Southern Latium region of Central Italy to identify flow paths, recharge areas and hydrochemical processes governing the evolution of groundwater in this region. The hydrogeological conceptual model of the carbonate aquifers of southern Latiu...

We perform a detailed study of the static and dynamical properties of molecular oxygen adsorption on Ag(110) based on semi-local density functional theory (DFT) calculations and compare the results to experimental studies. For the classical dynamics calculations we use two complementary approaches, ab initio molecular dynamics and dynamics on a precalculated potential energy surface. In contras...

Pulmonary embolism (PE) is a clinical entity with high mortality rate and therefore rapid diagnosis is necessary. For this purpose many diagnostic strategies have been developed for avoiding or necessitating further investigations. The hallmark of these strategies is assessing the pretest clinic probability of PE. In this study, the effectiveness of Wells, Geneva and Kline methods were investig...
