Prediabetes is an incremental risk factor for adverse cardiac events: A nationwide analysis.

Background And Aims: Prediabetes is defined as a state of impaired glucose metabolism with hemoglobin A1c (HbA1c) levels that precede those of a diabetic state. There is increasing evidence that suggests that hyperglycemic derangement in prediabetes leads to microvascular and macrovascular complications even before progression to overt diabetes mellitus. We aim to identify the association of prediabetes with acute cardiovascular events.

Maintenance of long-term adequate levels of vitamin d lowers HbA1c in African American patients with type 2 diabetes.

Objectives: We examined the long-term effects of enhanced Vitamin D (VitD) supplementation on parameters of type 2 diabetes mellitus (T2DM): serum hemoglobin A1c, low density lipoprotein, high density lipoprotein, and triglyceride for the purpose of determining beneficial VitD levels in T2DM African Americans (AA).

Design And Methods: Following inclusion criteria, retrospective charts of patients aged > or = 30 years were reviewed. VitD supplementation was given to patients as part of drug regimen over a three year continuum.
