Item First Trimester Maternal Lipid Levels and Serum Markers of Small-And Large-For-Gestational Age Infants(2014) Parlakgumus, Huriye Ayse; Aytac, Pinar Caglar; Kalayc, Hakan; Tarim, Ebru; 23617575; AAC-9940-2020Objective: To investigate if first trimester lipids, sonographic parameters and serum markers are related to small-and large-for-gestational age (SGA, LGA) infants. Methods: This study was conducted at Baskent University Adana Research Center between December 2009 and July 2011 and enrolled 433 women. Blood samples were drawn to measure fasting blood glucose, serum triglycerides, cholesterol, very low-density lipoprotein, low-density lipoprotein, high-density lipoprotein, f beta-hCG and pregnancy associated protein-A (PAPP-A) at the first trimester. Crown rump length and nuchal translucency were measured as suggested by the fetal medicine foundation. Results: LGA group was significantly taller (p = 0.016) and SGA group had significantly greater BMI (0.025). SGA fetuses were born at a significantly earlier gestational age (p = 0.001). Univariate analysis revealed that LGA group had significantly lower cholesterol (p = 0.038) and LDL levels (p = 0.041). PAPP-A was significantly lower in SGA Group compared with LGA Group (0.027). After controlling for age, parity, height, pre-pregnant BMI, weight gain during pregnancy and fasting blood sugar, none of the lipids, serum markers or sonographic parameters was related to LGA. PAPP-A was the only parameter significantly associated with SGA after multivariate analysis (p = 0.008). Conclusion: PAPP-A was significantly associated with SGA after controlling for confounders.Item Analysis of the effectiveness of ultrasound and clinical examination methods in fetal weight estimation for term pregnancies(2015) Zahran, Mehmet; Tohma, Yusuf Aytac; Erkaya, Salim; Evliyaoglu, Ozlem; Colak, Eser; Coskun, Bora; 28913073Objective: To compare the accuracy of clinical and ultrasonographic (USG) estimation of fetal weight in non-complicated, term pregnancies. Materials and Methods: Two hundred term pregnant women were included in the study. We used three formulae for the estimation of fetal weight at term; the Hadlock formula for the USG method, and two different formulas for clinical methods, maternal symphysis-fundal height and abdominal circumference at the level of umbilicus. Accuracy was determined by mean percentage error, mean absolute percentage error and proportion of estimates within 10% of actual birth weight (birth weight +/- 10%). Patients were divided into two groups according to actual birth weight, the normal birth weight group (2500-3999 g) and high birth weight group (>= 4000 g). Results: All three methods statistically overestimated birth weight for the high and normal birth weight groups (p<0.001, p=1.000, p=0.233) (p=0.037, p<0.001, and p<0.001). For both groups, the mean absolute percentage errors of USG were smaller than for the other two clinical methods and the number of estimates were within 10% of actual birth weight for USG was greater than for the clinical methods; the differences were statistically significant (p<0.001). No statistically significant difference of accuracy was observed for all three methods for the high birth weight group (p=0.365, p=0.768, and p=0.540). However, USG systematically underestimated birth weight in this group. Conclusion: For estimation of fetal birth weight in term pregnancies, ultrasonography is better than clinical methods. In the suspicion of macrosomia, it must be remembered that no method is better than any other. In addition, if ultrasonography is used, careful management is recommended because ultrasonography overestimates in this group.
