AbstractTo investigate the relation between first-trimester fetal growth discrepancy, as assessed by crown-rump length (CRL) at 11+0 to 13+6 weeks of gestation, and subsequent development of preeclampsia (PE) in dichorionic diamniotic (DCDA) twin pregnancies. The association between inter-twin CRL and birth weight (BW) discrepancy was also investigated.This was a retrospective, case-control study of DCDA twin pregnancies. Inter-twin CRL discrepancy was calculated as 100×(larger CRL–smaller CRL)/larger CRL. BW discordance was calculated as 100×(larger BW–smaller BW)/larger BW.The study included 299 DCDA pregnancies that remained normotensive and 35 that subsequently developed PE. There was no significant difference in the inter-twin CRL discrepancy between pregnancies complicated by PE and those that were not [3.2%, interquartile range (IQR): 0.5–4.5% vs. 3.3%, IQR: 1.4–5.5%; P=0.17]. There was a positive correlation between inter-twin CRL and BW discrepancy but only in pregnancies that remained normotensive (P<0.001). In women that subsequently developed PE, there was no association between inter-twin CRL and BW discordance (P=0.54).In unselected DCDA twins, first-trimester CRL discrepancy is not different between pregnancies that subsequently develop PE and those that remain normotensive. Furthermore, in pregnancies that are complicated by PE, the association between inter-twin CRL and BW discrepancy appears to be lost.

The aims of this study were to compare perineal distensibility between women with twin and singleton pregnancies and to correlate these women’s perineal distensibility with anthropometric data. This prospective cross-sectional case-control study was conducted among nulliparous women, of whom 20 were pregnant with twins and 23 with a single fetus. Perineal distensibility was evaluated in the third trimester by means of Epi-no, which was introduced into the vagina and inflated up to the maximum tolerable limit. It was then withdrawn while inflated and its circumference was measured. The unpaired Student’s t-test was used to compare perineal distensibility in the two groups and Pearson’s correlation coefficient (r) was used to correlate the pregnant women’s perineal distensibility with their anthropometric data. There was no difference in perineal distensibility between the twin group (16.51 ± 2.05 cm) and singleton group (16.13 ± 1.67 cm) (P=0.50). There was a positive correlation between perineal distensibility and abdominal circumference (r=0.36; P=0.01). The greater the abdominal circumference was, the greater the perineal distensibility was, regardless of whether the pregnancy was twin or singleton.

Background: This study aims to investigate whether maternal SARS-CoV-2 status affect placental pathology. Methods: A retrospective case-control study was conducted by reviewing charts and slides of placentas between April 1 to July 24, 2020. Clinical history of COVID-19 were searched in Pathology Database (CoPath). Controls were matched with SARS-CoV-2-negative women with singleton deliveries in the 3rd-trimester. Individual and group, pathological features were extracted from placental pathology reports. Results: Twenty-one 3rd-trimester, placentas from SARS-CoV-2-positive women were identified and compared to 20 placentas from SARS-CoV-2-negative women. There were no significant differences in individual or group gross or microscopic pathological features between the groups. Within the SARS-CoV-2+ group, there are no differences between symptomatic and asymptomatic women. Conclusion: Placentas from SARS-CoV-2-positive women do not demonstrate a specific pathological pattern. Pregnancy complicated with COVID-19 during the 3rd trimester does not have a demonstrable effect on placental structure and pathology.
