Efficacy of continuous glucose monitoring in improving glycemic control and reducing hypoglycemia: a systematic review and meta-analysis of randomized trials.

Objective: We conducted a systematic review and meta-analysis to assess the efficacy of continuous glucose monitoring (CGM) in improving glycemic control and reducing hypoglycemia compared to self-monitored blood glucose (SMBG).

Methods: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and Scopus for randomized trials of adults and children with type 1 or type 2 diabetes mellitus (T1DM or T2DM). Pairs of reviewers independently selected studies, assessed methodological quality, and extracted data.

Glycemic control in the medical intensive care unit.

Hyperglycemia in the critically ill is a well-known phenomenon, even in those without known diabetes. The stress response is due to a complex interplay between counter-regulatory hormones, cytokines, and changes in insulin sensitivity. Illness/infection, overfeeding, medications (e.

Incretins in the ICU: is insulin on its way out?

Incretins such as glucagon-like peptide-1 (GLP-1) are gut-derived hormones that stimulate insulin secretion and suppress glucagon secretion, thus playing a key role in glucose homeostasis. While incretin mimetics and enhancers are approved for treatment of outpatients with diabetes, evidence is only starting to accumulate regarding the therapeutic potential of incretins in hospitalized patients. Small exploratory studies suggest that GLP-1 safely reduces hyperglycemia without causing hypoglycemia, a key advantage over insulin if efficacy is established in larger studies.
