Reviewing your preferred digest of abstracts, you notice a study comparing emergency physicians' interpretation of chest radiographs with radiologists' interpretations. 1 The article catches your eye because you have frequently found that your own reading of a radiograph differs ...

OBJECTIVE To investigate the agreement between two international criteria for classification of children and adolescents nutritional status. METHODS The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index. Nutritional status was classified according to the cut-off points defined by the World Health O...

This paper presents a methodology to incorporate both hyperspectral properties and spatial coordinates of pixels in maximum likelihood classification. Indicator kriging of ground data is used to estimate, for each pixel, the prior probabilities of occurrence of classes which are then combined with spectral-based probabilities within a Bayesian framework. In the case study (mapping of in-stream ...

Although the third heart sound (S3) is well recognized as an important sign in the evaluation of patients with congestive heart failure, the interobserver variability with its observation needs to be known before general applicability can be determined. Therefore, we determined the agreement among four trained observers on the presence of S3 in 81 hospitalized patients. Agreement between pairs ...

We compared manual and computer-assisted bloodstream infection surveillance for adult inpatients at two hospitals. We identified hospital-acquired, primary, central-venous catheter (CVC)-associated bloodstream infections by using five methods: retrospective, manual record review by investigators; prospective, manual review by infection control professionals; positive blood culture plus manual C...

BACKGROUND Health administrative data is increasingly being used for chronic disease surveillance. This study explored agreement between administrative and survey data for ascertainment of seven key chronic diseases, using individually linked data from a large population of individuals in Ontario, Canada. METHODS All adults who completed any one of three cycles of the Canadian Community Healt...

The purpose of this paper is to extend the single-subject Eve atlas from Johns Hopkins University, which currently contains diffusion tensor and T1-weighted anatomical maps, by including contrast based on quantitative susceptibility mapping. The new atlas combines a "deep gray matter parcellation map" (DGMPM) derived from a single-subject quantitative susceptibility map with the previously esta...

BACKGROUND The performance of the WHO recommendations for pediatric antiretroviral treatment (ART) in resource poor settings is insufficiently documented in routine care. METHODS We compared clinical and immunological criteria in 366 children aged 0 to 12 years in Kinshasa and evaluated a simple computation to estimate CD4 percent, based on CD4 count, total white blood cell count and percenta...

The research was conducted to empirically validate the proposed maturity model of e-Government implementation, composed of four dimensions, further specified by 54 success factors as attributes. To do so, there are two steps were performed. First, expert’s judgment was conducted to test its content validity. The second, reliability study was performed to evaluate inter-rater agreement by using ...

To assess the reliability of responses to questionnaires regarding previous illness, family history of cancer, and smoking and drinking habits, we repeated questionnaire surveys four times at intervals of 2 weeks and 1 year (short-term), and 4.5 years (long-term) among 440 subjects aged 40-69. The reliability was assessed using kappa statistic. Kappa was calculated both for complete data and da...
