AI Article Synopsis
- Research focuses on maternal-fetal surgery to repair fetal abnormalities, with a review of conditions like twin-twin transfusion syndrome and congenital diaphragmatic hernia.
- Data from 1980 to 2010 were analyzed, revealing 258 relevant studies, predominantly observational, with limited randomized controlled trials and well-defined inclusion criteria.
- While the field is advancing, overall study quality and evidence strength are still insufficient for optimal clinical guidance in maternal-fetal care.
Article Abstract
Objective: To summarize the state of research in maternal-fetal surgery regarding the surgical repair of abnormalities in fetuses in the womb.
Data Sources: We searched MEDLINE from 1980 to 2010 for studies of maternal-fetal surgery for the following conditions: twin-twin transfusion syndrome, obstructive uropathy, congenital diaphragmatic hernia, myelomeningocele, thoracic lesions, cardiac malformations, and sacrococcygeal teratoma.
Methods Of Study Selection: We used pilot-tested data collection forms to screen publications for inclusion and to extract data. We compiled information about how fetal diagnoses were defined, maternal inclusion criteria, type of surgery, study design, country, setting, comparators used, length of follow-up, outcomes measured, and adverse events.
Tabulation, Integration, And Results: Two reviewers independently extracted data and discordance was resolved by a third party. Of 1,341 articles located, we retained 258 (comprising 166 unique study populations). Three studies were randomized controlled trials; the majority of the evidence was observational (116 case series [70%], 36 retrospective [22%], and 11 prospective [7%] cohorts). Twin-twin transfusion is the most studied condition, with 84 studies including 2,532 pregnancies. Fewer than 500 pregnancies are represented in the literature for each of the other conditions except congenital diaphragmatic hernia (n=503). Inclusion criteria were poorly specified. Outcomes typically measured were survival to birth, preterm birth, and neonatal death. Longer-term outcomes were sparse but included pulmonary, renal, and neurologic status and developmental milestones. Maternal outcome data were rare.
Conclusion: Although developing rapidly, maternal-fetal surgery research has yet to achieve the typical quality of studies and aggregate strength of evidence needed to optimally inform care.

Preeclampsia is a life-threatening complication that develops in 2-8% of pregnancies. It is characterized by elevated blood pressure after 20 weeks of gestation and may progress to multiorgan dysfunction, leading to severe maternal and fetal morbidity and mortality. The only definitive treatment is delivery, and efforts are focused on early risk prediction, surveillance, and severity mitigation.

Background: The postpartum period provides an opportunity for birthing people with opioid use disorder (OUD) to consider their future reproductive health goals. However, the relationship between the use of medication for opioid use disorder (MOUD) and contraception utilization is not well understood. We used multistate administrative claims data to compare contraception utilization rates among postpartum people with OUD initiating buprenorphine (BUP) versus no medication (psychosocial services receipt without MOUD (PSY)) in the United States (US).

Abortion can be a very stressful experience for women, and many social and psychological factors can influence this stress. The present study aims to investigate the impact of perceived social support on the marital satisfaction of women who have undergone an abortion. The study also explored whether resilience played a mediating role in this relationship.

Article Synopsis
- Prenatal exome sequencing (ES) successfully identified both fetal and maternal genetic diagnoses, revealing a shared pathogenic gamma globin variant in a fetus with unexplained anemia and a mother with sickle cell disease (SCD).
- The identified variant, HbF Mission Bay HBG2, is linked to various blood-related conditions, including cyanosis and hemolytic anemia, which generally emerge in infancy but can persist into adulthood.
- In this case, the mother's own symptoms from the variant, such as recurrent hypoxia and methemoglobinemia during pregnancy, occurred alongside the fetus's need for multiple blood transfusions and post-birth methemoglobinemia.
Resolution of selective fetal growth restriction after laser surgery for twin-to-twin transfusion syndrome can be predicted by predisease growth discordance.

Johns Hopkins Center for Fetal Therapy, Department of Gynecology and Obstetrics, Johns Hopkins University School of Medicine, Baltimore, MD, USA.
Objective: To determine if the resolution of fetal growth discordance after laser surgery in pregnancies with twin-to-twin transfusion syndrome (TTTS) and coexisting selective fetal growth restriction (sFGR) can be predicted by estimated fetal weight (EFW) discordance recorded prior to the development of TTTS (pre-TTTS).
Methods: This was a single-center, retrospective analysis of prospectively collected data on monochorionic twins with concurrent TTTS and sFGR that underwent laser surgery and had available growth ultrasound records from a pre-TTTS ultrasound evaluation. Maternal demographics, pregnancy characteristics and birth outcomes were compared between three outcome groups: double twin survival with resolved sFGR determined by birth weight discordance (BWD) < 20%; double twin survival with ongoing sFGR determined by BWD ≥ 20%; and single or double fetal demise after laser surgery.
