  • Closed-loop insulin systems are effective for daytime and overnight use.

 Why this matters

  • Continuous glucose monitoring (CGM) devices combined with insulin pumps provide real time monitoring and correction of blood glucose levels around the clock. 

Study design

  • The performance of closed-loop continuous glucose monitoring CGM) / insulin pump systems and their ability to prevent hypoglycemia was highlighted in two studies.
  • The first investigated the safety and feasibility of a new hybrid system in 12 children (average age nine).
  • This trial consisted of a 36-h, inpatient, closed-loop assessment with meals ranging from 30 to 90 grams of carbohydrates and limited physical activity.
  • The second study analyzed if exercise-related hypoglycemia can be reduced through a system that responds automatical...
