Aims/IntroductionTo measure longitudinal changes in resting energy expenditure and body composition of Japanese pregnant women with or without diabetes.Materials and MethodsThe study population consisted of women who had delivered a live singleton neonate after 22 weeks’ gestation at Okayama University Hospital from July 2013 to June 2017. Resting energy expenditure and body composition were measured in the first trimester, second trimester, third trimester and postpartum.ResultsA total of 144 women participated in this study: 103 with normal glucose tolerance and 41 with diabetes. The resting energy expenditure (kcal/day) of pregnant women with normal glucose tolerance was significantly higher in the third trimester (1,644 ± 234) than in the first (1,461 ± 215) and second trimesters (1,491 ± 219), and postpartum (1,419 ± 254), whereas that of pregnant women with diabetes did not significantly change during all periods (1,568 ± 404, 1,710 ± 332, 1,716 ± 251, 1,567 ± 249). The resting energy expenditure of women with good glycemic control was lower than that of women with poor control. Fat‐free mass was closely correlated with resting energy expenditure.ConclusionsThe resting energy expenditure of Japanese pregnant women with normal glucose tolerance was significantly increased in the third trimester. The resting energy expenditure of women with good glycemic control was lower than that of women with poor control. Resting energy expenditure and fat‐free mass are potential indexes for medical nutrition therapy in pregnant women with diabetes.

Cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy. Because CSP carries a high risk of uterine rupture and life-threatening bleeding, the pregnancy should be terminated upon confirmation of diagnosis. There have been few reports of CSP with successful delivery. We present a case of CSP under expectant management, with delivery via planned cesarean section at 35 weeks of gestation. This report suggests that successful pregnancy outcome can be achieved in some women with uterine cesarean scar, but further analysis and additional studies are required in order to describe the optimal protocol of expectant management in CSP.
