In Pregnancy

The role of cystatin C (Cys-C) as a marker of glomerular filtration rate (GFR) in pregnancy is undetermined. Measurements of Cys-C and creatinine (Cr) were taken at 14–17+6, 18–23+6, 27–31+6 weeks' gestation, at delivery and 2–6 weeks postpartum in a prospective observational study of 27 women. There was no difference between Cys-C levels in early and late second trimester, but they were significantly higher in early third trimester ( P < 0.001) than second trimester, despite no concurrent increase in Cr. Cys-C was also significantly higher at delivery than at all other times in pregnancy ( P < 0.001) and fell to postpartum values higher than second trimester measurements ( P < 0.01), but lower than delivery ( P<0.001). In conclusion, changes in Cys-C may be influenced by pregnancy-related changes in glomerular filtration and therefore we would advise against their use as a marker of GFR in pregnancy.

ObjectivesTo assess the influence of second child intent on the delivery preferences and final delivery modes of nulliparous women, particularly caesarean delivery on maternal request (CDMR), after implementation of China’s two child policy.DesignCross sectional and prospective observational study.SettingA tertiary teaching hospital in Chongqing, China.Participants1000 low risk nulliparous women were initially involved, and were divided into two groups based on their intent on having a second child. 814 women who completed all interviews were analysed.Main outcome measuresPreferred mode of delivery in second trimester and at admission; final delivery mode, CDMR.Results814 women who completed all interviews were analysed, in whom 51.2% intended to have a second child. The preference for caesarean delivery (CD) at the second trimester between the intent and no intent group was 6.2% versus 17.9% (adjusted RR 0.35, 95% CI 0.20 to 0.63) and increased to 24.2% versus 37.3% (adjusted RR 0.65, 95% CI 0.45 to 0.94) at admission, respectively. The overall CD rates between the two groups were 41.0% versus 50.4% (adjusted RR 0.84, 95% CI 0.60 to 1.18), and the CDMR rates were 16.7% versus 29.0% (adjusted RR 0.56, 95% CI 0.37 to 0.86), respectively.ConclusionsWomen who intend to have a second child are less likely to request a CD, and high rates of CD and CDMR in nulliparous women may have decreased after implementation of China’s two child policy.
