Objective To compare the endocrine cord blood characteristics of offspring from obese mothers with those of offspring from healthy controls. Methods Cross-sectional case control study., Setting: University medical centers., Patient(s): Offspring from obese mothers (n = 41) and healthy controls (n = 31)., Intervention(s): Cord blood withdrawal from neonates., Main Outcome Measure(s): Cord blood total cholesterol (TC), triglycerides (TGs), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), blood glucose (GL) and insulin (Ins). Result(s) Fetal GL and TGs were reduced in the offspring of obese women when compared to those in the offspring of the controls. The mean cord blood GL level was 47.8 mg/dL standard deviation (SD 33.1) in the offspring of the obese group vs. 57.9 mg/dL (SD 12.5) in the offspring of the control group, and the mean cord blood TG level was 26.5 (SD 33.6) in the offspring of the obese group vs. 34.6 (SD 12.3) in the offspring of the control group. Maternal obesity was also associated with reduced levels of TC and HDL-C in the pregnant women. Conclusion The observed results suggest that GL and TGs in the cord blood of the offspring of obese mothers were significantly lower than those in the offspring of the control group.

Objective: The aim of this study was to assess fetal urinary production rates (FUPR) in twin gestations using 3D ultrasonography with VOCAL® (virtual organ computer-aided analysis) and to develop a curve of normal values for the target population., Methods: A cross-sectional study was performed in 30 normal twin pregnancies with gestational ages ranging from 20 to 34 weeks. FUPR was measured using a three-dimensional ultrasound (3D US) virtual organ computer-aided analysis (VOCAL) system. FUPR (ml/hour) was calculated during the filling phase using the equation UPR = (VFB(2) - VFB(1))/time. The values for UPR were plotted as a function of fetal biometry (biparietal diameter) to generate a nomogram., Results: A total of 41 normal twin fetuses with gestational ages between 20 and 34 weeks were investigated. Eleven were excluded because of inadequate bladder contour image quality and/or the observation of micturition in one or both fetuses. Linear regression analysis of FUPR as a function of biparietal diameter (BPD) shows the normal range for UPR by fetal biometry and is expressed by the following equation: Ln(UPR) = -5.0121 + 0.0548 BPD (R(2) 0.3386, p value <.001). There was no statistically significant difference when the UPR was stratified by chorionicity., Conclusions: The use of biometric parameters to predict fetal FUPR seems to be useful. In twin pregnancies, BPD is the variable that is most closely related to FUPR. For each 1 mm increase in BPD, there is a 5% increase in FUPR. Chorionicity did not affect FUPR.
