Background: The national waste rate for hospital-issued blood products ranges from 0% to 6%, with operating room-responsible waste representing up to 70% of total hospital waste. A common reason for blood product waste is inadequate intraoperative storage.

Study Design And Methods: Our transfusion service database was used to quantify and categorize red blood cell (RBC) and fresh-frozen plasma (FFP) units issued for intraoperative transfusion that were wasted over a 27-month period.

Aircraft-mounted sensors were used to measure the exchange of carbon dioxide above a cornfield, a forest, and a lake under midday conditions. Mean absorption values of 3400, 1200, and 100 milligrams of carbon dioxide per square meter per hour, respectively, are consistent with reported ground-based observations of carbon dioxide flux. Such information, gathered by aircraft, could be used to provide a quantitative evaluation of source and sink distributions of carbon dioxide in the biosphere, to establish a correlation between satellite data and near-surface measurements, and to monitor crop performance.

To evaluate the effect of diabetic control on sterol balance, five subjects (one with fasting chylomicronemia) were studied when they had little control of blood glucose (period I) and, continuously, when increased insulin dosage improved diabetic control (period II). The four subjects with no chylomicronemia showed a diminished fecal bile acid (FBA) excretion. Although fecal neutral steroid excretion increased variably, the total steroid balance was unchanged.
