Ovarian hyperstimulation syndrome and adverse pregnancy outcome
No full textINTRODUCTION: The aim of this study was to investigate the association between ovarian hyperstimulation syndrome (OHSS) and adverse pregnancy outcome.EVIDENCE ACQUISITION: Medline, Embase and Cochrane databases were searched. The primary outcome was a composite score of adverse maternal outcome including either preterm birth (PTB), gestational diabetes mellitus (GDM), pre-eclampsia (PE) or pregnancy induced hypertension. intrahepatic cholestasis of pregnancy, thromboembolic events or need for caesarean section (CS). Secondary outcomes were a composite score of adverse fetal outcome including either miscarriage, low birthweight, fetal anomalies or intrauterine fetal death (IUD) and the individual components of both primary and secondary outcomes.EVIDENCE SYNTHESIS: Thirteen studies (3303 ART pregnancies with and 89,720 without OHSS) were included. The risk of composite adverse maternal outcome (RR: 8.8, 95% CI: 8.1-9.5) was higher in women with compared to those without OHSS. The association between OHSS and adverse pregnancy outcome was mainly due to the higher risk of PTB (RR: 11.4. 95% CI: 10.5-12.4), while there was no difference in the risk of others primary outcome. Likewise, the risk of composite fetal outcome was higher in pregnancies with a prior OHSS (RR: 1.5, 95% CI: 1.1-2.0). The strength of association between OHSS and composite adverse maternal outcome persisted when considering singleton pregnancies or those with severe disease.CONCLUSIONS: Pregnancies complicated by OHSS are at high risk of adverse pregnancy outcome, especially PTB

Maternal outcomes of cesarean delivery performed at early gestational ages: a systematic review and meta-analysis
No full textOBJECTIVE: This study aimed to report maternal outcomes of preterm (<34 weeks of gestation) cesarean delivery. DATA SOURCES: Medline, Embase, and ClinicalTrials.gov databases were searched electronically on September 1, 2020, utilizing combinations of the relevant medical subject heading terms, key words, and word variants for "cesarean delivery" and "outcome." STUDY ELIGIBILITY CRITERIA: We included only studies reporting maternal outcomes of cesarean delivery performed at <34 weeks of gestation. STUDY APPRAISAL AND SYNTHESIS METHODS: The primary outcome was a composite score of maternal surgical morbidity including maternal death, severe intrasurgical or postpartum hemorrhage, hysterectomy, need for blood transfusion, and damage to adjacent organs. Secondary outcomes were individual components of the primary outcome, need for reoperation, postsurgical infection, thromboembolism, and hysterectomy. We also performed 2 subgroup analyses considering cesarean delivery performed at <28 and <26 weeks of gestation. Meta-analyses of proportions using random effects model were used to combine data. RESULTS: A total of 15 studies involving 8378 women undergoing cesarean delivery at <34 weeks of gestation were included in the systematic review. Composite adverse maternal outcome was reported in 16.2% of women (95% confidence interval, 15.4-17.0) undergoing a cesarean delivery before 34 weeks of gestation. Hemorrhage, either intra- or postoperative, was observed in 6.9% of cases (95% confidence interval, 6.4-7.5), whereas 6.3% (95% confidence interval, 4.2-8.7) required blood transfusion. Damage to adjacent organs complicated the primary surgery in 2.0% of women (95% confidence interval, 0.1-6.4), whereas 1.2% (95% confidence interval, 0.3-3.4) required a reoperation after cesarean delivery. Maternal death occurred in 0.1% (95% confidence interval, 0.0-1.4). In women undergoing cesarean delivery at <28 weeks of gestation, composite adverse maternal outcome complicated 22.9% of cases (95% confidence interval, 16.7-33.8) and 14.0% (95% confidence interval, 5.8-24.9) experienced hemorrhage whereas 7.7% (95% confidence interval, 4.4-11.8) required blood transfusion. Finally, when considering women undergoing cesarean delivery at <26 weeks of gestation, composite adverse maternal outcome was reported in 24.8% (95% confidence interval, 10.1-43.4), whereas the corresponding figures for hemorrhage and need for blood transfusion were 9.2% (95% confidence interval, 1.7-21.6) and 6.1% (95% confidence interval, 0.3-10.0), respectively. CONCLUSION: Early cesarean delivery is affected by a high rate of maternal intra- and postoperative complications. The findings from systematic review can help clinicians in counseling parents when cesarean delivery is required in an early gestational age. Copyright © 2021 Elsevier Inc. All rights reserved
Extracellular Vesicles in pregnancy: Their potential role as a liquid biopsy
No full textExtracellular Vesicles (EVs) are cell-derived particles released during different pathophysiological processes, circulating in many body fluids and mediating the inter-cellular crosstalk. We have analyzed, for the first time, different EV phenotypes and concentrations in the peripheral blood of uncomplicated pregnant women

No full textCorticosteroid prophylaxis for fetal immaturity in a pregnant patient with atrial myxoma
No full textWe report a case of a woman at 32nd gestational week, admitted for resting dyspnea, showing left atrial (LA) myxoma. Cardiac myxomas are the most common primary benign tumors of the heart. The incidence of cardiac myxomas diagnosed in pregnancy is extremely low.In the present case, cesarean delivery and concomitant surgical resection of LA myxoma were both delayed after corticosteroid prophylaxis in order to reduce neonatal cerebral, intestinal, and pulmonary complications.<. Learning objective: The rarity of these cases makes the management more related to anecdotal experiences. In our case, the gestational age was lower than 34th week, but the fetus was sufficiently large to be delivered before heart surgery with low risk of prematurity complications after an adequate corticosteroid prophylaxis. A waiting approach with several days of corticosteroid prophylaxis was successfully adopted. When the pregnant hemodynamics are stable with low risk of complications, heart surgery should be delayed after corticosteroid prophylaxis
Induction of labor in late-FGR
No full textLate-onset FGR is a peculiar condition characterized by the inability for the fetus to reach its growth potential diagnosed from 32 weeks of gestation. Placental insufficiency is among the leading causes of late FGR and is commonly due to a primary maternal cardiovascular non-adaptation potentially leading to fetal decompensation during labor especially once exposed to uterine hyperstimulation. Abnormalities that usually characterize late FGR include reduced fetal growth, decreased amniotic fluid index, and loss of fetal heart rate variability at CTG. Fetal hemodynamics study by Doppler ultrasound significantly improved management of pregnancies affected by fetal growth restriction. A major issue when dealing with pregnancies complicated by late FGR is how to induce these women. Induction of labor (IOL) can be essentially accomplished by pharmacological and non-pharmacological agents. Recent studies suggested that the pregnancies complicated by late FGR should undergo a tailored approach for IOL in view of the higher risk of fetal decompensation following uterine hyperstimulation. The present review aims to provide an up to date on the different types of IOL which can guide clinical management
Comparison between trans-vaginal and trans-abdominal ultrasound examination of the cervix in the second trimester of pregnancy: a prospective study
No full textobjectives: to compare transvaginal (TV) and trans-abdominal (TA) ultrasound assessment of cervical length (CL) at the time of the second-trimester scan for fetal anomalies. methods: this was a prospective study including consecutive pregnant women attending the low-risk ultrasound clinic of two fetal medicine centres in Italy. the inclusion criteria were women between 19 + 0 and 22 + 0 weeks of gestation, attending the prenatal ultrasound clinic for the routine second trimester screening for fetal anomalies. the primary outcome was to compare the CL measurement obtained at TV compared to TA ultrasound; the secondary outcome was to report the inter and intra-observer variability of CL measured with the two different approaches. all women underwent TV and TA assessment of the cervix performed by two experienced certified operators, blinded to each other. intra-class correlation coefficients (ICC) and bland-altman analyses were used to analyse the data. results: two hundred and fifty women were included in the analysis. all women had anteverted uterus. the mean gestational age at ultrasound was 20.7 ± 0.7 weeks; 1.2 % (3/250) scans were performed at 19 weeks, 49.2 % (123/250) at 20 weeks, 44.8 % (112/250) at 21 weeks and 4.8 % (12/250) at 22 weeks of gestations. Identification of the major landmarks of CL at TA ultrasound was achieved in all the included cases. there was good reliability between CL measured at TA (ICC 0.95, 95 % CI 0.93-0.97 for observer 1 and 0.92 %, 95 % CI 0.89-0.94 for observer 2) and TV ultrasound 0.97, 95 % CI 0.96-0.98 for observer 1 and 0.96, 95 % CI 0.95-0.97 for observer 2). there was also good reliability between the two observers for both the TA and TV assessment of the CL. mean TA CL was 41.4 ± 5.5 for observer 1 and 40.5 ± 4.8 for observer 2 with no significant differences between the two measurements (mean difference 0.92 mm, 95 % CI -9.7 to 11.2). likewise, there was no difference between the CL measured at TV ultrasound between the two observers (mean difference -0.83 mm, 95 % CI -5.97 to 4.30). finally, there was no difference in the mean CL measured at TA compared to TV, either considering the overall population of women (mean difference: -0.43, 955 CI -8.65 to 7.79), or when stratifying the analysis according to the parity status and the operator. conclusions: among experienced operators, there was no difference between TV and TA ultrasound assessment of the CL at the time of the routine anomaly scan for fetal anomaly
