Does maternal diabetes delay fetal pulmonary maturity?

Article Abstract:

Poor control of blood sugar among pregnant women with diabetes appears to slow development of fetal lungs. Of 829 pregnant women who underwent amniocentesis, 289 had diabetes and the 540 who did not have diabetes served as controls. Of the women with diabetes, 140 had good glucose control and 149 had poor glucose control. There were no significant differences in immaturity of fetal lungs between pregnant women with well-controlled diabetes and the controls. However, fetal lung immaturity occurred at a significantly higher rate among pregnant women with poor blood sugar control than among the controls. These findings suggest that not only is blood sugar control associated with fetal lung maturity but also that diabetic women with good blood sugar control need not have amniocentesis any more frequently than pregnant women without diabetes.

Are labor abnormalities more common in shoulder dystocia?

Article Abstract:

Problems with labor may not indicate whether delivery of an infant will be difficult because of large shoulders. Researchers reviewed 276 cases of shoulder dystocia, or difficult delivery of the shoulders, and compared these cases to those of normal vaginal deliveries. Both groups had similar rates of problems with labor. More patients with shoulder dystocia underwent induction of labor than did those without dystocia. The rate of vaginal delivery assisted by forceps or vacuum extraction was significantly higher for the shoulder dystocia group. Among women who had never had children before, prolonged pushing was associated with shoulder dystocia. Very large infants were more likely to cause shoulder dystocia.

Diurnal glycemic profile in obese and normal weight nondiabetic pregnant women

Article Abstract:

Using a novel approach that provides continuous measurement of blood glucose, the study sought to evaluate the ambulatory daily glycemic profile in the second half of pregnancy in nondiabetic women. It is suggested that stringent glycemic control and mimicking normal glycemic profile in pregnancy, that is complicated with diabetes mellitus, is associated with enhanced perinatal outcome.
