Summary
Tandem Diabetes Care
Area of Science:
- Endocrinology
- Diabetes Technology
Background:
- The t:slim X2 insulin pump uses Control-IQ technology.
- This system is compatible with both Dexcom G6 and G7 continuous glucose monitors (CGMs).
Purpose of the Study:
- To compare CGM-derived metrics in individuals transitioning from Dexcom G6 to G7 sensors while using the Control-IQ system.
- To assess the impact of the sensor transition on glycemic control outcomes.
Main Methods:
- Retrospective analysis of CGM data from t:slim X2 pump users.
- Comparison of glucose metrics during the final 30 days of G6 sensor use and the initial 30 days of G7 sensor use.
- Evaluation of time in range (TIR), time below range (TBR), and time in closed-loop.
Main Results:
- Median TIR and TBR remained stable, with changes less than 1% after transitioning from G6 to G7 sensors.
- Glycemic control metrics, including time in closed loop and median glucose levels, showed clinically insignificant differences.
- Users maintained excellent glycemic control with both G6 and G7 sensors.
Conclusions:
- The transition from Dexcom G6 to G7 sensors does not negatively impact glycemic control for t:slim X2 insulin pump users with Control-IQ technology.
- Control-IQ system users achieve similar and excellent glycemic outcomes regardless of using G6 or G7 sensors.
- The interoperability of the t:slim X2 pump with newer CGM technology ensures consistent diabetes management.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
