Purpose: Currently available randomized trial evidence has shown no reductions in type 2 diabetes (T2D) complications important to patients with tight glycemic control. Yet, economic analyses consistently find tight glycemic control to be cost-effective. To understand this apparent paradox, we systematically identified and appraised economic analyses of tight glycemic control for T2D.

Article Synopsis
  • The diagnosis and procedures for ankyloglossia (tongue-tie) in the U.S. have surged, particularly for newborns, leading to debates about the need for frenotomy and its benefits.
  • A case study highlights a 6-week-old infant who developed a sublingual mucocele post-laser frenotomy, prompting a systematic review for major complications linked to the procedure.
  • The review revealed 47 major complications across 34 pediatric cases, such as poor feeding and airway issues, indicating a significant lack of reporting on the risks involved with frenotomy in neonates.
