Current and future commitment to hematology research.

This article provides an overview of the National Heart Lung and Blood Institute's (NHLBI) current and future commitment to hematology research. The paper comprises nine sections: (1) a brief history of how NHLBI incorporated blood research in its mission; (2) a summary of the traditional areas of research interest for blood diseases and resources; (3) a description of how NHLBI has assured and continues to assure a safe blood supply; (4) the current and future plans for transfusion medicine and cellular therapy research; (5) research support for hemoglobinopathies and red cell disorders; (6) research support for thrombosis and hemostatic disorders; (7) current and future research of hematopoietic stem cell biology, and aplastic and preneoplastic conditions; (8) future training for hematologists, and (9) a concluding summary.

Effect of hemoglobin concentration variation on the accuracy and precision of glucose analysis using tissue modulated, noninvasive, in vivo Raman spectroscopy of human blood: a small clinical study.

Tissue modulated Raman spectroscopy was used noninvasively to measure blood glucose concentration in people with type I and type II diabetes with HemoCue fingerstick measurements being used as reference. Including all of the 49 measurements, a Clarke error grid analysis of the noninvasive measurements showed that 72% were A range, i.e., clinically accurate, 20% were B range, i.e., clinically benign, with the remaining 8% of measurements being essentially erroneous, i.e., C, D, or E range. Rejection of 11 outliers gave a correlation coefficient of 0.80, a standard deviation of 22 mg/dL with p<0.0001 for N=38 and places all but one of the measurements in the A and B ranges. The distribution of deviations of the noninvasive glucose measurements from the fingerstick glucose measurements is consistent with the suggestion that there are at least two systematic components in addition to the random noise associated with shot noise, charge coupled device spiking, and human factors. One component is consistent with the known variation of fingerstick glucose concentration measurements from laboratory reference measurements made using plasma or whole blood. A weak but significant correlation between the deviations of noninvasive measurements from fingerstick glucose measurements and the test subject's hemoglobin concentration was also observed.
