Van Leeuwen et al reported a model for predicting gestational diabetes mellitus in a pregnant woman. This can help to identify a woman who should be monitored more closely and managed more aggressively. The authors are from Academic Medical Centre Amsterdam, Bronovo Hospital, University Medical Center Utrecht, Bethesda Hospital, and Isala Clinics in The Netherlands.
