Objectives:
Postpartum mothers with gestational diabetes may remain with either type 2 diabetes mellitus, impaired glucose tolerance or impaired fasting glucose. Our aim in this study was to identify maternal variables that could predict 1 or more of these conditions.
Methods:
In 193 singleton pregnancies with gestational diabetes, we applied bivariate logistic regression and receiver-operating characteristic curves to data from the index glucose-challenge test that allowed the diagnosis of gestational diabetes.
Results:
Receiver-operating characteristic curves of fasting glucose from the index glucose-challenge test predicted impaired fasting glucose and type 2 diabetes mellitus combined, with a sensitivity of 100%, false-positive rate of 40.5%, area under the curve of 0.849, p=0.004 and positive predictive value 45%, and with a cutoff point of 4.7 mmol/L.
Conclusions:
At the time of diagnosis of gestational diabetes during pregnancy, a basal glucose level of ≥4.7 mmol/L on index glucose-challenge test indicates a 45% probability of either type 2 diabetes mellitus or impending diabetes early postpartum.

01:20Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
