Which is the threshold glycose value for further investigation in pregnancy?
The aim of this study was to investigate the lower threshold glycose value in a 50 gr-1 hour screening test for further testing in diagnosing gestational diabetes mellitus (GDM). Our study consisted of 602 pregnant women between 24-28 weeks of gestation, who received a 50 gr glycose load followed by glycose determination one hour later. After screening 273 out of 602 women showed test serum glycose values > 125 mg/dl. All 273 women received a 100 gr 3-hour glycose tolerance test (GTT). Thirty out of 273 women were found to have carbohydrate intolerance. The overall incidence of GDM was 4.98%. When the threshold glycose value was > or = 130 mg/dl the incidence of GDM was 17.8%, but lowering the threshold to 126 mg/dl a further 1.3% of the women showed carbohydrate intolerance. In the above threshold value the sensitivity was 100% but the specificity was only 54%. However, we recommend 126 mg/dl threshold for GTT since this threshold allows for the diagnosis of all women with carbohydrate intolerance during pregnancy.

Smoking and preterm labor.
The aim of the present study was to investigate the role of maternal smoking during pregnancy in the occurrence of the premature rupture of the membranes (PROM) and premature labor . Our study consisted of 1,133 women of which 283 (group A) had premature labor (gestation < or = 37 weeks), while 850 (group B) had term labor (gestation > 37 weeks). The two groups did not differ in their socioeconomic status and did not include women with serious complications during pregnancy. There were no apparent effects of smoking on the length of gestation. However, our results showed that smoking had a marked effect on preterm labor of less than 32 weeks; we also found a statistically significant correlation between PROM in premature deliveries and smoking during pregnancy, but no gradient was observed between the number of cigarettes smoked per day and the risk for PROM, in cases of premature labor. We conclude that smoking during pregnancy raises the risk of delivery before the 32nd week, as well as the PROM in premature deliveries, independently of the number of cigarettes smoked per day.
