CONTEXT The impact of clinical decision support systems (CDSS) on antimicrobial prescribing in ambulatory settings has not previously been evaluated. OBJECTIVE To measure the added value of CDSS when coupled with a community intervention to reduce inappropriate prescribing of antimicrobial drugs for acute respiratory tract infections. DESIGN,(More)
Stool carriage of drug-resistant Escherichia coli in home-living residents of a rural community was examined. Carriage of nalidixic acid-resistant E. coli was associated with recent use of antimicrobial agents in the household. Household clustering of drug-resistant E. coli was observed. Most carriers of drug-resistant E. coli lacked conventional risk(More)
We assesseda manual nephelometerincorporating a laser as light source and an optical system that detects forward scatter for use in estimating apolipoprotein B (apoB) by immunonephelometry. Comparisons were made with a less-sensitive, automated immunoprecipitation system and with a radioimmunoassay. ApoB, cholesterol, and triglycerides were estimated on(More)
Two forms of vitamin C are recognized, ascorbic acid and dehydro-ascorbic acid. Although most of the vitamin exists as ascorbic acid, both forms appear to be utilized similarly by the human (Sabry et al., 1958). Many species of animals are able to synthesize ascorbic acid and do not require it in the diet. When deprived of a dietary source of vitamin C for(More)
The limitation of plasma sodium concentration as an indicator of extracellular hydration status in cases of acute diabetes is well recognized and could lead to individually inappropriate fluid therapy. However, in view of the small analytical and biological variations exhibited by plasma concentrations of protein, water, and sodium in health, we have(More)
The productivity of social groups depends critically on effective regulation of work effort among group members. In social insect colonies, regulation of work may be decentralised or alternatively may be controlled by one or a few individuals (‘pacemakers’) within the colony. Social parasites, which usurp host colonies and replace the dominant as the(More)
