BACKGROUND Framingham risk equations are widely used to predict cardiovascular disease based on health information from a single time point. Little is known regarding use of information from repeat risk assessments and temporal change in estimated cardiovascular risk for prediction of future cardiovascular events. This study was aimed to compare the discrimination and risk reclassification of a...

OBJECTIVE Although clinical training programs aspire to develop competency in violence risk assessment, little research has examined whether level of training is associated with the accuracy of clinicians' evaluations of violence potential. This is the first study to compare the accuracy of risk assessments by experienced psychiatrists with those performed by psychiatric residents. It also exam...

Although ecological risk assessments (ERAs) and natural resource damage assessments (NRDAs) are performed under different statutory and regulatory authorities, primarily the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), as currently practiced, the activities typically overlap. ERAs performed as part of the response process (typically by the US Environmental Prot...

This study aimed to qualify photosafety screening on the basis of photochemical and pharmacokinetic (PK) data on dermally applied chemicals. Six benzophenone derivatives (BZPs) were selected as model compounds, and in vitro photochemical/phototoxic characterization and dermal cassette-dosing PK study were carried out. For comparison, an in vivo phototoxicity test was also conducted. All of the ...

Since the 1980 U.S. Supreme Court decision on the Occupational Safety and Health Administration's (OSHA) proposal to lower the occupational benzene standard from 10 ppm to 1 ppm, numerous quantitative assessments of the leukemia risk of benzene exposure have been prepared. The primary difference between these risk assessments has been in the way in which benzene exposure has been estimated and ...

First, we described an illustrative notional planning magnitude for each threat based on a stylized threat and risk assessment, while noting that a more comprehensive threat and risk assessments could reveal that these illustrative magnitudes were either too high or too low. Our illustrative threat assessments relied on historical data revealing observed frequencies and consequences of each thr...

concentrations of cu, pb, cr, cd, mn, ni, fe and zn were determined in the muscle samplesof sarotherodon melanotheron from the fosu lagoon in cape coast using atomic absorption spectrophotometer. the results showed that, metal concentration in the fish muscle was in the order mn > zn > fe > pb > ni > cd > cu > cr. mean concentrations of pb and cd in the fish exceeded the maximum tolerable limit...

What is included in the integrated framework? In this document, we define the term integrated risk assessment as, a science-based approach that combines the processes of risk estimation for humans, biota, and natural resources in one assessment. Such an integrated approach can be applied to a wide variety of types of assessments including 1) assessments that predict the effects of proposed acti...

Eighty patients and thirty controls were interviewed using one interview that promoted personal disclosure and another about everyday topics. Speech was scored using the Thought, Language and Communication scale (TLC). All participants completed the Self-Concept Clarity Scale (SCCS) and the Varieties of Inner Speech Questionnaire (VISQ). Patients scored lower than comparisons on the SCCS. Low s...
