Objective: To evaluate whether the success rate of oral mifepristone was not inferior to that of Foley balloon catheter for outpatient cervical ripening of term pregnancies, and whether there were differences in side effects for mothers and newborns.

Design: Open-label, non-inferiority randomised controlled trial.

Setting: A tertiary care European university hospital in an urban setting.

Article Synopsis
  • The study aimed to determine if a simulation-based training course for external cephalic version (ECV) could increase its adoption in hospitals and improve success rates where it's already practiced.
  • Ten Portuguese public maternity hospitals participated, with specialists receiving training. The outcomes measured were the frequency and success rates of ECV performed over two years before and after the training.
  • Results showed that four additional hospitals began performing ECV after training, but no significant improvement in success rates was found in hospitals already doing it, highlighting the need for better access and centralized services for ECV.

Article Synopsis
  • The study aimed to compare complications in monochorionic (MC) twins from spontaneously conceived (SC) and assisted reproductive technologies (ART) pregnancies over a span of 10 years in a university hospital setting.
  • A total of 393 MC pregnancies were analyzed, revealing that hypothyroidism was significantly more common in ART pregnancies, along with a higher occurrence of congenital anomalies, particularly heart defects.
  • Overall, while there were no major differences in chorionicity complications or neonatal outcomes, ART pregnancies showed non-significant trends toward earlier delivery and lower birth weights compared to SC pregnancies.

Dapsone (DDS) therapy can frequently lead to hematological side effects, such as methemoglobinemia and DNA damage. In this study, we aim to evaluate the protective effect of racemic alpha lipoic acid (ALA) and its enantiomers on methemoglobin induction. The pre- and post-treatment of erythrocytes with ALA, ALA isomers, or MB (methylene blue), and treatment with DDS-NOH (apsone hydroxylamine) was performed to assess the protective and inhibiting effect on methemoglobin (MetHb) formation.

Introduction: The aim of this study was to evaluate the accuracy of 35-37 weeks' ultrasound for fetal growth restriction (FGR) detection and the impact of 30th-33rd weeks versus 30th-33rd and 35th-37th weeks' ultrasound on perinatal outcomes.

Methods: This was a randomized controlled trial that enrolled 1,061 low-risk pregnant women: 513 in the control group (routine ultrasound performed at 30th-33rd weeks) and 548 in the study group (with an additional ultrasound at 35th-37th weeks). FGR was defined as a fetus with an estimated fetal weight (EFW) below the 10th percentile.

Placenta accreta spectrum (PAS) disorders are an increasing health problem in many parts of the world. They are an important risk factor for adverse maternal outcomes related to delivery, with a reported 18-fold increase in maternal morbidity. Profuse haemorrhage after attempting to remove the placenta is the most frequent complication and can lead to major maternal morbidity and ultimately to maternal death.

Objective: To evaluate the incidence of abnormal third trimester oral glucose tolerance tests (OGTT) results in non-diabetic women and to compare the obstetric and neonatal outcomes with those of women with normal OGTT results.

Methods: Women with third trimester singleton pregnancies with negative gestational diabetes test results earlier in their pregnancy were enrolled into an observational prospective study at a tertiary care hospital between June 1, 2014 and September 30, 2017. All underwent an additional 75 g OGTT between 32 and 36 weeks and were classified as having normal or abnormal results.

Objective: To evaluate the effect of maternal weight on the intra- and inter-observer reproducibility of third-trimester ultrasonography fetal measurements.

Methods: The present prospective study, performed at a tertiary hospital, enrolled patients at between 35  weeks and 36  weeks of singleton pregnancies between January 1, 2015, and July 1, 2016. Fetal ultrasonography measurements were evaluated twice by a first observer and a third time by a second observer.

Introduction: The best route of delivery for the term breech fetus is still controversial. We aim to compare maternal and neonatal outcomes between vaginal and cesarean term breech deliveries.

Material And Methods: Multicentric retrospective cohort study of singleton term breech fetuses delivered vaginally or by elective cesarean section from January 2012 - October 2014.

Objective: To compare the effectiveness of anterior pelvic organ prolapse (POP) repair using Prolift (Ethicon, Somerville, NJ, USA) or Elevate (American Medical Systems, Minnetonka, MN, USA) vaginal mesh at 12 months of follow-up.

Methods: A retrospective study was undertaken using the records for the first 50 Prolift procedures in 2007-2009 and the first 50 Elevate procedures in 2013-2015 performed at a tertiary urogynecology unit in Lisbon, Portugal. Postoperative follow-up occurred at 3, 6, and 12 months.

Objectives: To compare delivery route and admission rate to neonatal intensive care unit between small- and appropriate-for-gestational-age babies among low-risk term pregnancies.

Methods: A retrospective study was conducted using the database of deliveries in 2014 at a tertiary hospital. Babies delivered at ≥37 weeks with birthweight <10th centile were considered small-for-gestational-age (SGA) and >90th centile were considered large-for-gestational-age.
