ABSTRACT
OBJECTIVE: To compare two portable lactate devices, Lactate Scout and StatStrip Xpress, to a laboratory reference device by assessing the concordance of cord blood lactate values at birth. METHODS: We conducted a single-center prospective validation study in a level 3 maternity hospital. For all cord samples taken at birth, we analyzed lactates on the reference device (GEM4000®) and on two portable devices Lactate Scout and StatStrip Xpress. We compared the lactate values from each of the two handheld devices to the reference device. RESULTS: A total of 101 samples were collected. Each was analyzed by all three machines. The average lactate value obtained by the different machines was 3.7mmol/L. The mean difference between the Lactate Scout and GEM4000® apparatus was 0.0mmol/L±0.8mmol/L. Between these two devices at lactate threshold of 4.8mmol/L, the negative predictive value was 96,2% (76/79) and the area under the curve was 0.98 (95% CI 0.96-1]. The mean difference between StatStrip Xpress and GEM4000® was 0.1mmol/L±0.7mmol/L. Between these two devices at the lactate threshold of 4.8mmol/L, the negative predictive value was 97,4% (76/78) and the area under the curve was 0.95 (95% CI 0.86-1). CONCLUSION: There is a good correlation between the lactates obtained by the reference device and the two portable devices Lactate Scout and StatStrip Xpress.

This article discusses evaluating and improving the health and quality of work life (QOWL) of nurses. Nurses are reported to have higher illness, disability, and absenteeism rates than all other health care workers. Research suggests that QOWL impacts nurses' health and the provision of quality health care, particularly patient safety. Occupational health nurses have a pivotal role in evaluating and improving nurses' QOWL and health. This will ensure quality health outcomes for nurses and patients and reduce costs for the health care system.

Phase separation and gelation induced by addition of monovalent and divalent cations in iota and kappa carrageenan solutions were investigated as a function of the polymer and cation concentrations. Rheological measurements have also been carried out at a given polymer concentration. The storage modulus (G') determined at a cation/polymer ratio was always higher for kappa- than for iota-carrageenan. For iota carrageenan, G' increased slowly with the monovalent salt concentration and more quickly with the divalent salt concentration. At the opposite, for kappa carrageenan, G' increased more rapidly in the presence of KCl than with calcium or copper. Nevertheless for large salt concentrations, G' became independent of the type and concentration of cations in the kappa carrageenan solution.
