Official Title ^ICMJE	Maternal Glucose Measurement in Pregnancy Using a Continuous Ambulatory Subcutaneous Monitor
Brief Summary	This proposal is a pilot study to describe the variations of blood sugar in pregnant women with various degrees of glucose intolerance, and how they relate to standardized meals. Blood sugar control during pregnancy is important to prevent complications for the newborn. The variation and timing of the blood sugar measurements in gestational diabetics and how this relates to the baby's outcome is controversial. We will use an FDA approved device called Minimed Glucose Continuous Monitor, which is used in clinical practice for certain diabetics. It is very small, similar to a beeper, and is connected to the patient through a small plastic catheter subcutaneously. This measures blood sugar every five minutes for a total of 288 readings a day with minimum discomfort. The hypothesis of this study is that use of the Minimed glucose monitor will provide information about variations of blood sugar in gestational diabetics that is missed by capillary glucose monitors. Our conclusions will allow us to compare blood glucose trends among the groups. After the data is analyzed in this pilot study, we plan to design a bigger study involving more subjects to study the impact of the blood sugar variations in the outcome of the newborn, and to obtain generalizable results for the population in general.
Detailed Description	We will coordinate the study through the CRC. The women will have to come in only twice, to have the monitor placed and then taken off three days later. A blood sample will be collected at each visit. Meals and snacks will be provided for each day of the study, specially packaged, to supply an equivalent amount of calories for each subject. These will meet the nutritional requirements for both the mother and the fetus. Women will do separate fingerstick blood sugar measurements using a capillary glucometer four times a day, to ensure the accuracy of the sensor's readings.
