Inductively coupled plasma mass spectrometric detection for multielement flow injection analysis and elemental speciation by reversed-phase liquid chromatography

The feasibility of using an inductively coupled plasma mass spectrometer as a muitieiement detector for flow injection analysis (FIA) and ion-pair reversed-phase liquid chromatography was investigated. Sample introduction was by uitrasonk nebulization with aerosol desolvation. Absolute detecton limits for FIA ranged from 0.01 to 0.1 ng for most elements using 10-pL injections. Over 30 elements were surveyed for their response to both anionic and cationic ion pairing reagents. The separation and selective detection of various As and Se species were demonstrated, yielding detection limits near 0.1 ng (as element) for ail six species present. Determination of 15 elements in a single injection with multiple ion monitoring produced shniiar detection limits. Isotope ratios were measured with sufficient precision (better than 2%) and accuracy (about 1 %) on eluting peaks of Cd and Pb to demonstrate that liquid chromatographyhductively coupled plasma mass spectrometry should make speciation studies with stable tracer isotopes feasible

Primary care patients' recognition of their own risk for cardiovascular disease: implications for risk communication in practice.

Item does not contain fulltextPURPOSE OF REVIEW: Guidelines on primary prevention of cardiovascular disease emphasize identifying high-risk patients for intensive risk-reducing management. These guidelines recommend the identification of individuals with high risk using risk score sheets or risk tables. Patients' misperceptions of risk seem to hamper implementation of the high-risk approach. How appropriate are the risk perceptions of patients? What is known about effective ways of risk communication? RECENT FINDINGS: Cardiovascular risk is often perceived inappropriately in primary care populations; by nearly four in five high-risk patients (incorrect optimism), and by one in five low-risk patients (incorrect pessimism). Communicating cardiovascular risk by means of natural frequencies seems effective to correct inappropriate risk perception, though effects are small. SUMMARY: In communicating cardiovascular disease risk, primary care physicians must be aware that they mostly encounter low-risk patients and that the perceived risk does not necessarily correspond with the actual risk. Professionals should be skilled in the use of effective formats for risk communication that are ideally integrated within patient decision aids for cardiovascular risk management
