New Generation of AbbottMonitor Sports Extra Features

On June 5, 2004, Abbott Laboratoriesintroduced the new and improved PrecisionXtra Advanced Diabetes ManagementSystem.

The monitor offers advanced diabetesmanagement capabilities, including:

  • Two-step testing
  • Three-button design for easier testing andprogramming
  • Backlight for testing in low light
  • 450-test memory with seven-, 14- and 30-day averaging results
  • TrueMeasure technology test strips foralternate-site testing.

In addition, the Precision Xtra can measureblood ketones using separate ketone teststrips, making it the first home monitor tohave such a feature.

CGMS Shows Extended LifeBeyond Current 72 Hours

The new version of Medtronic MiniMedContinuous Glucose Monitoring System(CGMS) provides “accurate glucose valuesand trend information without requiringthat the user calibrate the device while it isworn,” say Stanford University researchers. Inaddition, the CGMS allows for daily activitiessuch as showering.

In a study to determine if the CGMS withwireless transceiver can safely extendbeyond the current labeling of 72 hoursfor “active pediatric patients,” 10 childrenwith type 1 wore two CGMS devicessimultaneously for seven days. In addition,patients self-monitored blood glucoseduring the study with the BD Paradigm Link.

According to the researchers, 18 sensorscontributed data by the end of the study,resulting in 94 and a half days of experience.CGMS life was 126 hours or approximatelyfive days.

There were 10 and a half hours of gaps incontinuous glucose monitoring that did notcontribute to data; these were attributedto system events, such as calibration error,sensor out of range and sensor disconnect.

The FreeStyle NavigatorWarns of Lows

The FreeStyle Navigator is TheraSense’scontinuous glucose monitor, which in arecent study correctly identified 92.4 percentof all low blood glucose events.

The FreeStyle Navigator wirelesstransmitting system has a tinyelectrochemical glucose sensor that isinserted beneath the skin into the interstitialfluid for three days.

Don’t Count on BG‘Guesstimates’

Kids and Parents offthe Mark

School-aged kids with type1 and their parents exhibitpoor overall ability todetect high and low bloodglucose (BG) fluctuations.Using handheld computers,27 children ages 6 to 11and their parents rated thechild’s current symptoms,recent food intake andexercise and then estimatedthe current BG level priorto measuring it three tofour times a day over aone-month period. Acrossall BG ranges, parents andchildren made clinicallyaccurate estimates 29and 23 percent of thetime, respectively. Failureto detect low BGs wasthe most common error.The Virginia and Bostonresearchers suggest thatblood glucose awarenesstraining (BGAT) may beuseful for this population.
