  ABSTRACT: Low total weight gain during pregnancy has been widely accepted as a valid risk factor for small-for-gestational-age infants and pre-term births. However, it is not obvious in which trimester the weight gain rate most affects birth weight and length of gestation. Using logistic regression analysis and Pearson's correlation coefficient test, data from 472 women who had vaginally delivered an infant at term without any complications were analyzed retrospectively. Pre-pregnancy underweight and low total maternal weight gain were significant independent predictors of small-for-gestational-age infants and shortened gestations. Pre-pregnancy weight was significantly related to the birth weight and length of gestation (r = 0.18, p < 0.0001; r = 0.10, p = 0.04, respectively), and total weight gain was also significantly related to those (r = 0.17, p = 0.0003; r = 0.11, p = 0.03, respectively). Significant correlations between maternal weight gain rate in the second trimester and the birth weight and length of gestation were found (r = 0.32, p = 0.005; r = 0.40, p = 0.0003, respectively), while such correlations were not found in the first or third trimester. The most sensitive period of maternal weight gain for the birth weight and length of gestation was the second trimester.

  ABSTRACT: A woman with lactate dehydrogenase M-subunit deficiency underwent two cesarean sections because of the risk of dystocia due to decreased adenosine triphosphate production in anaerobic glycolysis including uterine muscles. Frequent pains with increased serum pyruvate levels were observed during the third trimester of her pregnancies.
